Overview

California Water Service Group is a holding company with seven operating subsidiaries: California Water Service Company (Cal Water), New Mexico Water Service Company (New Mexico Water), Washington Water Service Company (Washington Water), Hawaii Water Service Company, Inc. (Hawaii Water), TWSC, Inc. (Texas Water), and CWS Utility Services and HWS Utility Services LLC (CWS Utility Services and HWS Utility Services LLC being referred to collectively in this annual report as Utility Services). Cal Water, New Mexico Water, Washington Water, and Hawaii Water are regulated public utilities. Texas Water holds regulated and contracted wastewater utilities.

The regulated utility entities also provide some non-regulated services. Utility Services holds non-utility property and provides non-regulated services to private companies and municipalities outside of California (see Non-Regulated Activities below for more details). Cal Water was the original operating company and began operations in 1926.

Our business is conducted through our operating subsidiaries and we provide utility services to approximately two million people. The bulk of the business consists of the production, purchase, storage, treatment, testing, distribution and sale of water for domestic, industrial, public and irrigation uses, and the provision of domestic and municipal fire protection services. In some areas, we provide wastewater collection and treatment services, including treatment which allows water recycling. We also provide non-regulated water-related services under agreements with municipalities and other private companies. The non-regulated services include full water system operation, billing and meter reading services. Non-regulated operations also include the lease of communication antenna sites, lab services and promotion of other non-regulated services.

During the year ended December 31, 2021, there were no significant changes in the kind of products produced or services rendered by our operating subsidiaries, or in the markets or methods of distribution.

Regulated Business

California water operations are conducted by Cal Water, which provides service to approximately 494,500 customer connections in approximately 100 California communities through 21 separate districts, which are subject to regulation by the California Public Utilities Commission (CPUC). California water operations accounted for approximately 90.3% of our total customer connections and 91.9% of our total consolidated operating revenue.

We operate the City of Hawthorne and the City of Commerce water systems under lease agreements. In accordance with the lease agreements, we receive all revenues from operating the systems and are responsible for paying the operating costs. The City of Hawthorne and the City of Commerce lease revenues are governed through their respective city councils and are considered non-regulated because they are outside of the CPUC's jurisdiction. We report revenue and expenses for the City of

Table of Contents

Hawthorne and City of Commerce leases in operating revenue and operating expenses because we are entitled to retain all customer billings and are responsible for all operating expenses. These leases are considered "nontariffed products and services" (NTPS) by the CPUC and require a 10% revenue sharing with regulated customers.

In October of 2011, an agreement was negotiated with the City of Hawthorne to lease and operate its water system. The system, which is located near the Hermosa Redondo district, serves about half of Hawthorne's population. The capital lease agreement required an up-front $8.1 million lease deposit to the city that is being amortized over the lease term. Additionally, annual lease payments will be adjusted based on changes in rates charged to customers. Under the lease, we are responsible for all aspects of system operation and capital improvements, although title to the system and system improvements reside with the city. Capital improvements are recorded as depreciable plant and equipment and depreciated per the asset lives set forth in the agreement. In exchange, we receive all revenue from the water system, which was $11.4 million, $10.5 million, and $9.5 million in 2021, 2020, and 2019, respectively. At the end of the lease, the city is required to reimburse us for the unamortized value of capital improvements made during the term of the lease. The City of Hawthorne capital lease is a 15-year lease and expires in 2026.

In April of 2018, a renewal agreement was negotiated with the City of Commerce for us to continue to lease and to operate its water system for 15 years. Under the agreement, the operating lease requires us to pay $0.8 million per year in monthly installments. We have operated the City of Commerce water system since 1985 and are responsible for all operations, maintenance, water quality assurance, customer service programs, and financing capital improvements to provide a reliable supply of water that meets federal and state standards to customers served by the City of Commerce system. The City of Commerce retains title to the system and system improvements and remains responsible for setting its customers’ water rates. We bear the risks of operation and collection of amounts billed to customers. In exchange, we receive all revenue from the water system, which was $3.4 million, $2.9 million, and $2.9 million in 2021, 2020, and 2019, respectively. The agreement allows us to request a rate change annually in order to recover costs.

Hawaii Water provides service to approximately 6,200 water and wastewater customer connections on the islands of Maui, Oahu, and Hawaii, including several large resorts and condominium complexes. Hawaii Water's regulated customer connections are subject to the jurisdiction of the Hawaii Public Utilities Commission (HPUC). Hawaii Water accounts for 1.1% of our total customer connections and approximately 4.5% of our total consolidated operating revenue.

Washington Water provides domestic water service to approximately 36,400 customer connections in the Tacoma, Olympia, Graham, Spanaway, Puyallup, and Gig Harbor areas. Washington Water's utility operations are regulated by the Washington Utilities and Transportation Commission. Washington Water accounts for approximately 6.6% of our total customer connections and approximately 2.7% of our total consolidated operating revenue.

New Mexico Water provides service to approximately 8,600 water and wastewater customer connections in the Belen, Los Lunas, Indian Hills, and Elephant Butte areas in New Mexico. New Mexico's regulated operations are subject to the jurisdiction of the New Mexico Public Regulation Commission. New Mexico Water accounts for approximately 1.6% of our total customer connections and 0.6% of our total consolidated operating revenue.

In May of 2021, Texas Water became the majority owner of BVRT, a Texas-based utility development company owning and operating four wastewater utilities serving growing communities outside of Austin and San Antonio. Texas Water initially invested funds to enable BVRT to continue to build wastewater infrastructure and converted its investment to equity. BVRT’s five wastewater utilities currently serve or are under contract to serve over 1,900 customer connections, with an estimated potential total build-out of more than 61,000 connections. Texas Water accounts for approximately 0.4% of our total customer connections and 0.3% of our total consolidated operating revenue.

The state regulatory bodies governing our regulated operations are referred to as the Commissions in this annual report. Rates and operations for regulated customers are subject to the jurisdiction of the respective state's regulatory Commission. The Commissions require that water and wastewater rates for each regulated district are independently determined based on the cost of service. The Commissions are expected to authorize rates sufficient to recover normal operating expenses and allow the utility to earn a fair and reasonable return on invested capital.

We distribute and treat water and treat wastewater in accordance with accepted water utility methods. Where applicable, we hold franchises and permits in the cities and communities where we operate. The franchises and permits allow us to operate and maintain facilities in public streets and right-of-ways as necessary.

Non-Regulated Activities

Non-regulated revenue and expenses consist primarily of the operation of water systems that are owned by other entities under lease agreements, leasing of communication antenna sites on our properties, billing of optional third-party insurance programs to our residential customers, and unrealized gains or losses on benefit plan investments.

Table of Contents

Fees for non-regulated activities are based on contracts negotiated between the parties. Under our non-regulated contract arrangements, we operate municipally owned water systems and privately owned water and recycled water distribution systems, but are not responsible for all operating costs. Non-regulated revenue received from non-leased water system operations is generally determined on a fee-per-customer basis.

In California, nearly all non-regulated activities are now considered NTPS. The prescribed accounting for these NTPS is incremental cost allocation plus revenue sharing with regulated customers. Non-regulated services determined to be "active activities" require a 10% revenue sharing, and "passive activities" require a 30% revenue sharing. The amount of non-regulated revenues subject to revenue sharing is the total billed revenues less any authorized pass-through costs. Some examples of CPUC authorized pass-through costs are purchased water, purchased power, and pump taxes. All of our non-regulated services, except for leasing communication antenna sites on our properties, are "active activities" subject to a 10% revenue sharing. Leasing communication antenna sites on our properties are "passive activities" subject to a 30% revenue sharing. Cal Water's annual revenue sharing with regulated customers was $3.1 million, $2.5 million, and $2.7 million in 2021, 2020, and 2019, respectively.

Operating Segment

We operate in one reportable segment, the supply and distribution of water and providing water-related utility services. For information about revenue from external customers, net income attributable to California Water Service Group and total assets, see "Item 8. Financial Statements and Supplementary Data."

Growth

We intend to continue exploring opportunities to expand our regulated and non-regulated water and wastewater activities, particularly in the western United States. The opportunities could include system acquisitions, lease arrangements similar to the City of Hawthorne and City of Commerce contracts, utility development investments similar to the BVRT investment, full service system operation and maintenance agreements, meter reading, billing contracts and other utility-related services.

Rates and Regulation

The Commissions have plenary powers setting both rates and operating standards. As such, the Commissions' decisions significantly impact the Company's revenues, earnings, and cash flows. The amounts discussed herein are generally annual amounts, unless otherwise stated, and the financial impact to recorded revenue is expected to occur over a 12-month period from the effective date of the decision. In California, water utilities are required to make several different types of filings. Certain filings, such as General Rate Case (GRC) filings, escalation rate increase filings, and offset filings, may result in rate changes that generally remain in place until the next GRC. As explained below, surcharges and surcredits to recover balancing and memorandum accounts as well as GRC interim rate relief are temporary rate changes, having specific time frames for recovery.

The CPUC follows a rate case plan which requires Cal Water to file a GRC for each of its regulated operating districts (except Grand Oaks) every three years. In a GRC proceeding the CPUC not only considers the utility's rate setting requests, but may also consider other issues that affect the utility's rates and operations. The CPUC is generally required to issue its GRC decision prior to the first day of the test year or authorize interim rates. In accordance with the rate case plan, Cal Water filed its most recent GRC application in July of 2021 requesting rate changes effective January 1, 2023.

Between GRC filings, Cal Water may file escalation rate increases, which allow Cal Water to recover cost increases, primarily from inflation and incremental investments, during the second and third years of the rate case cycle. However, escalation rate increases are district specific and subject to an earnings test. The CPUC may reduce a district’s escalation rate increase if, in the most recent 13-month period, the earnings test reflects earnings in excess of what was authorized for that district.

In addition, California water utilities are entitled to make offset requests via advice letter. Offsets may be requested to adjust revenues for construction projects authorized in GRCs when those capital projects go into service (these filings are referred to as "rate base offsets"), or for rate changes charged to Cal Water for purchased water, purchased power, and pump taxes (which are referred to as "expense offsets"). Rate changes approved in offset requests remain in effect until the next GRC is approved.

In pursuit of the State of California's water conservation goals, the CPUC decoupled Cal Water's revenue requirement from customer consumption levels in 2008 by authorizing a Water Revenue Adjustment Mechanism (WRAM) and Modified Cost Balancing Account (MCBA) for each district. The WRAM and MCBA ensure that Cal Water recovers revenues authorized by the CPUC regardless of customer consumption. This has removed the historical disincentive against promoting

lower water usage among customers. Through an annual advice letter filing, Cal Water recovers any under-collected metered revenue amounts authorized, or refunds over-collected metered revenues, via surcharges and surcredits. The advice letters are generally filed in April of each year and address the net WRAM and MCBA balances recorded for the previous calendar year. The majority of WRAM and MCBA balances are collected or refunded through surcharges/surcredits over 12 and 18 months. The WRAM and MCBA amounts are cumulative, so if they are not amortized in a given calendar year, the balance is carried forward and included with the following year balance. Cal Water also has a Sales Reconciliation Mechanism (SRM) in place for 2021 and 2022 (the second and third years of its 2018 GRC), that allows the company to adjust its adopted sales forecast if actual sales vary from adopted sales by more than 5.0% in the prior year in a district. The SRM moderates the growth of the net WRAM and MCBA balances until the next GRC.

The CPUC issued a decision effective August 27, 2020 requiring that Class A companies submitting GRC filings after the effective date be (i) precluded from proposing the use of a full decoupling WRAM and (ii) allowed the use of Monterey-Style Water Revenue Adjustment Mechanisms (MWRAM) and Incremental Cost Balancing Accounts (ICBA). The MWRAM tracks the difference between the revenue received for actual metered sales through the tiered volumetric rate and the revenue that would have been received with the same actual metered sales if a uniform rate had been in effect. The ICBA tracks differences in the authorized prices of water production costs and actual prices of water production costs. Cal Water has complied with this decision in its recent 2021 GRC filing.

Regulatory Activity - California

2021 GRC Filing

On July 2, 2021, Cal Water filed its 2021 GRC requesting water infrastructure investments of $1.0 billion in accordance with the rate case plan for all of its regulated operating districts for the years 2022, 2023, and 2024. The CPUC will evaluate the water infrastructure improvement investments along with operating budgets to establish water rates that reflect the actual cost of service. The CPUC will also evaluate Cal Water's proposed rate design changes that would improve revenue stability and provide a discounted unit rate to the first six units of water per month for residential customers. In the proposal, this block of usage would be charged at 25% of the second tier rate. The CPUC has recognized this six-unit block as essential for basic needs. As part of the rate design changes, Cal Water has also proposed the use of a MWRAM and ICBA. The required filing was the start of an approximately 18-month review process, with any changes in customer rates expected to become effective in 2023. Cal Water has proposed to the CPUC to increase revenues by $80.5 million, or 11.1%, in 2023; $43.6 million, or 5.4%, in 2024; and $43.2 million, or 5.1%, in 2025 to support these investments. If approved as filed, we expect that the average residential customer bill would increase less than $5 per month across all of Cal Water’s service areas. Cal Water is in the process of reviewing parties’ recommendations, evaluating the validity of underlying data, and composing rebuttal testimony. Settlement negotiations with the California Public Advocates Office and intervenors will begin in the second quarter of 2022, and evidentiary hearings are scheduled for the second quarter of 2022. Any rate change because of this filing is expected to be effective on January 1, 2023.

Escalation Increase Requests

As a part of the decision on the 2018 GRC, Cal Water was authorized to request annual escalation rate increases for 2021 and 2022 for those districts that passed the earnings test. In December of 2020, Cal Water requested escalation rate increases for 2021 in 13 of its regulated districts. The increase in annual adopted gross revenue associated with the December 2020 filing was $8.2 million. The new rates were implemented on February 1, 2021.

In November of 2021, Cal Water requested escalation rate increases for 2022 in 19 of its regulated districts. The increase in annual adopted gross revenue associated with the November 2021 filing was $21.7 million. The new rates were implemented on January 1, 2022.

Expense Offset Requests

Expense offsets are dollar-for-dollar increases in revenue to match increased expenses, and therefore do not affect net operating income. In November of 2020, Cal Water submitted an advice letter to request offsets for increases in purchased water costs and pump taxes in seven of its regulated districts totaling $5.5 million. The new rates were implemented on February 1, 2021.

In September of 2021, Cal Water submitted an advice letter to request offsets for increases in purchased water costs and pump taxes in one of its regulated districts totaling $1.8 million. The new rates were implemented on October 1, 2021.

In December of 2021, Cal Water submitted an advice letter to request offsets for increases in purchased water costs and pump taxes in seven of its regulated districts totaling $5.2 million. The new rates were implemented on January 1, 2022.

Table of Contents

Rate Base Offset Requests

For construction projects authorized in GRCs as advice letter projects, Cal Water is allowed to request rate base offsets to increase revenues after the project goes into service. In July of 2020, Cal Water submitted an advice letter to recover $9.0 million of annual revenue increase for a rate base offset in one of its regulated districts. The new rates were implemented on February 1, 2021.

In November of 2021, Cal Water submitted an advice letter to recover $0.2 million of annual revenue increase for a rate base offset in one of its regulated districts. The new rates were implemented on January 1, 2022.

WRAM/MCBA Filings

In April of 2021, Cal Water submitted an advice letter to true up the revenue under-collections for the 2020 annual WRAMs/MCBAs of its regulated districts. A net under-collection of $39.6 million is being recovered/refunded from/to customers in the form of 12, 18, and greater-than-18-month surcharges and 6 and 12-month surcredits. The new rates incorporate net WRAM/MCBA balances that were previously approved for recovery, and were implemented on April 15, 2021.

Interim Rates Memorandum Account

The 2018 GRC was approved in December of 2020. Final rates for the 2018 GRC were implemented as of February 1, 2021. As a result, Cal Water calculated and recorded a regulatory asset of $55.7 million and a corresponding increase to revenue for the difference between final rates and interim rates for the 13-month period January 1, 2020 to January 31, 2021. Cal Water also recorded a regulatory liability of $1.6 million and a corresponding decrease to regulatory assets for LIRA and RSF program credits that would have been given to customers had the rate case been approved on time.

In the second quarter of 2021, Cal Water submitted advice letters to request amortization of the IRMA. The new rates were implemented on June 15, 2021. The net under collection of IRMA is being recovered/refunded in the form of 13, 18, 24, and 36-month surcharges and 13-month surcredits.

2015 GRC PCBA and HCBA Filings

During the first six months of 2021, Cal Water submitted advice letters to amortize the PCBA and HCBA from the 2015 GRC that tracked the difference between adopted and actual costs for the period of 2017-2019. For the PCBA, $21.3 million is being recovered from customers in the form of 12 and 24-month surcharges as actual pension costs during 2017-2019 were higher than the adopted pension costs. For the HCBA, $4.3 million is being refunded to customers in the form of 12 month surcredits as actual health care costs during 2017-2019 were lower than the adopted health care costs. The new rates were implemented on June 15, 2021.

Cost of Capital Application

By order of the CPUC in its rate case plan for water utilities, Cal Water and three other large water companies (scheduled companies) were required to request a review of their cost of capital for 2021 through 2023 by May 1, 2020. On January 22, 2020, Cal Water and the scheduled companies requested the CPUC to allow a one-year extension to file their Cost of Capital applications by May 1, 2021, rather than May 1, 2020. As part of the request, the companies proposed that there be no changes to their respective costs of capital during the one-year extension. This condition mirrored the condition included in the CPUC’s previous approvals of the water companies’ requests for cost of capital extensions. The companies indicated that postponing the filing one year would alleviate administrative processing costs and provide relief for both CPUC and company resources already strained by numerous CPUC proceedings. On March 11, 2020, the CPUC granted Cal Water and the scheduled companies an extension to May 1, 2021 to file their cost of capital application. As the filing due date fell on a weekend, the filing was due on the following business day of May 3, 2021.

On May 3, 2021, Cal Water filed its required application with the CPUC to review its cost of capital for 2022 through 2024. Cal Water requested a return on equity of 10.35%, a cost of debt of 4.23%, and a 53.4% equity capital structure. The CPUC will evaluate the proposal along with proposals of other parties, and in accordance with its standard process, is currently expected to issue a decision in the third quarter of 2022. In past rate proceedings, the Commission has made rates retroactive to the first day of the original test period, which in this case is January 1, 2022.

California Drought Memorandum Account (DRMA)

In June of 2021, Cal Water submitted advice letters to request a DRMA to track the incremental operational and administrative costs incurred to further implement updated Rule 14.1 for voluntary conservation measures and Schedule 14.1 for mandatory rationing measures, including activities related to enhanced conservation efforts, staffing, and capital expenditures to ensure a safe, reliable supply of water. The DRMA would also track monies paid by customers for fines,

penalties, or other compliance measures associated with water use violations; and penalties paid by Cal Water to its water wholesalers. The advice letters were approved by the CPUC with an effective date of June 14, 2021.

Palos Verdes Peninsula Water Reliability Project (Project)

In 2002, Cal Water commissioned a Water System Master Plan (Master Plan) for the Palos Verdes water system. The Master Plan identified the high-priority need to augment the existing potable water system with new transmission mains and a new pump station to improve the capacity and reliability of the water system. This resulted in the development of a capital project known as the Project. Before the Project, a single pipeline that is over 60 years old delivered potable water to approximately 90 percent of the Peninsula, and a second pipeline of the same age delivered water to the remaining 10 percent. Both of these pipelines were approaching the end of their useful lives.

The CPUC authorized Cal Water to recover revenue associated with costs up to a cap of $96.1 million after the Project is in service, subject to the CPUC’s reasonableness review. In 2020, the Project was completed and an Advice Letter 2387 asking for authority to increase rates reflecting the Project costs up to the cap, with an effective date of August 27, 2020 was filed. The advice letter was approved on January 29, 2021. New rates were implemented on February 1, 2021, with the revenue requirement being effective as of August 27, 2020.

Due to the complexity of the project, Cal Water estimates total project costs exceeded the advice letter cap of $96.1 million. Amongst other things, the 2021 GRC filing requests authority to open a memorandum account allowing Cal Water to track incremental capital-related costs associated with this project.

Regulatory Activity - Other States

2021 Washington Water GRC (Washington Water)

On July 15, 2021, Washington Water filed a GRC application with the Washington Utilities and Transportation Commission (WUTC) requesting a phased-in consolidation of its East Pierce Water System with its legacy Washington Water system. The requested annual revenue increase is $3.1 million and is proposed to be implemented over 3 years. After working with the WUTC and Public Counsel, the Company updated its application on February 2, 2022 with a revised annual revenue increase of $1.0 million and eliminated the 3-year rate increase proposal. The WUTC approved the GRC application on February 10, 2022 with an effective date of February 15, 2022.

Kona Water Service Company GRC (Hawaii Water)

In May of 2021, Hawaii Water submitted a private letter ruling (PLR) to the IRS requesting a ruling on the treatment of deferred taxes because of the TCJA. A favorable decision on the PLR was received on November 18, 2021. Hawaii Water is awaiting direction from the HPUC.

Kapalua Water Company and Kapalua Waste Treatment Company (Hawaii Water)

In the first quarter of 2021, Hawaii Water Service received approval from the Hawaii Public Utilities Commission (HPUC) to acquire the assets of Kapalua Water Company and Kapalua Waste Treatment Company from Maui Land and Pineapple Company. Hawaii Water took control of the water and wastewater systems on May 1, 2021.

HOH Utilities Company (Hawaii Water)

In June of 2021, Hawaii Water signed an agreement to acquire the assets of HOH Utilities Company, a wastewater utility located in the growing Poipu/Koloa area of Kauai County on the island of Kauai. The acquisition is subject to satisfaction of customary closing conditions, including approval by the HPUC.

Hawaii Water is expected to own and manage the wastewater utility, which currently serves almost 1,800 residential, commercial, and resort customers in Poipu and Koloa, including three hotels, condominiums, multi-family housing, a golf course, and single-family homes.

An application for approval of the transaction was submitted to the HPUC in September of 2021. A commission decision is expected in the third quarter of 2022.

Keauhou Community Services, Inc. (Hawaii Water)

In December 2020, Hawaii Water entered into an asset purchase agreement with Keauhou Community Services, Inc. (KCSI). KCSI is a utility that provides wastewater service in the Keauhou area of North Kona. The acquisition is subject to satisfaction of customary closing conditions, including approval by the HPUC.

Table of Contents

Hawaii Water has operated the system under an operations and maintenance agreement since 2018. Upon close, Hawaii Water will own and operate the utility, which consists of residential, commercial, and resort customers.

An application for approval of the transaction was submitted to the HPUC in October of 2021. A commission decision is expected in the fourth quarter of 2022.

Kalaeloa Water Company GRC (Hawaii Water)

In August of 2021, a GRC application requesting an increase of revenues for Kalaeloa was submitted with the HPUC. If approved, the combined increase for water and sewer service revenue is $0.3 million. A commission decision is expected in the third quarter of 2022.

BVRT Utility Holding Company (BVRT) (Texas Water)

In May of 2021, Texas Water became the majority owner of BVRT, a Texas-based utility development company owning and operating four wastewater utilities serving growing communities outside of Austin and San Antonio. Texas Water initially invested funds to enable BVRT to continue to build wastewater infrastructure and converted its investment to equity. BVRT’s five wastewater utilities currently serve or are under contract to serve over 3,800 connections, with an estimated potential total build-out of more than 61,000 connections.

Water Supply

Our source of supply varies among our operating districts. Certain districts obtain all of their supply from wells; some districts purchase all of their supply from wholesale suppliers; and other districts obtain supply from a combination of wells and wholesale suppliers. A small portion of supply comes from surface sources and is processed through Company-owned water treatment plants. To the best of management's knowledge, we are meeting water quality, environmental, and other regulatory standards for all Company-owned systems.

Historically, approximately half of our annual water supply is pumped from wells. State groundwater management agencies operate differently in each state. Some of our wells extract ground water from water basins under state ordinances. These are adjudicated groundwater basins, in which a court has settled the dispute between landowners, or other parties over how much annual groundwater can be extracted by each party. All of our adjudicated groundwater basins are located in the State of California. Our annual groundwater extraction from adjudicated groundwater basins approximates 5.4 billion gallons or 10.3% of our total annual water supply pumped from wells. Historically, we have extracted less than 100% of our annual adjudicated groundwater rights and have the right to carry forward up to 20% of the unused amount to the next annual period. All of our remaining wells extract ground water from managed or unmanaged water basins. There are no set limits for the ground water extracted from these water basins. Our annual groundwater extraction from managed groundwater basins approximates 32.1 billion gallons or 61.1% of our total annual water supply pumped from wells. Our annual groundwater extraction from unmanaged groundwater basins approximates 15.0 billion gallons or 28.6% of our total annual water supply pumped from wells. Most of the managed groundwater basins we extract water from have groundwater recharge facilities. We are required to financially support these groundwater recharge facilities by paying well pump taxes. Our well pump taxes for 2021, 2020, and 2019 were $15.3 million, $12.6 million, and $11.5 million, respectively. In 2014, the State of California enacted the Sustainable Groundwater Management Act of 2014. The law and its implementing regulations require most basins to select a sustainability agency by 2017, develop a sustainability plan by the end of 2022, and show progress toward sustainability by 2027. We expect that after the act's provisions are fully implemented, substantially all the Company's California groundwater will be produced from sustainably managed and adjudicated basins.

California's normal weather pattern yields little precipitation between mid-spring and mid-fall. The Washington Water service areas receive precipitation in all seasons, with the heaviest amounts during the winter. New Mexico Water's rainfall is heaviest in the summer monsoon season. Hawaii Water receives precipitation throughout the year, with the largest amounts in the winter months. Water usage in all service areas is highest during the warm and dry summers and declines in the cool winter months. Rain and snow during the winter months in California replenish underground water aquifers and fill reservoirs, providing the water supply for subsequent delivery to customers. As of December 31, 2021, the State of California snowpack water content during the 2021-2022 water year is 51% of long-term averages (per the California Department of Water Resources, Northern Sierra Precipitation Accumulation report). The northern Sierra region is the most important for the state’s urban water supplies. The central and southern portions of the Sierras have recorded 58% and 55%, respectively, of long-term averages. Management believes that, notwithstanding higher-than-average snowpack water content, supply pumped from underground aquifers and purchased from wholesale suppliers will be adequate to meet customer demand during 2022 and thereafter. Long-term water supply plans are developed for each of our districts to help assure an adequate water supply under various operating and supply conditions. Some districts have unique challenges in meeting water quality standards, but management believes that supplies will meet current standards using currently available treatment processes.

Table of Contents

On May 31, 2018, California's Governor signed two bills (Assembly Bill 1668 and Senate Bill 606) into law that will establish long-term standards for water use efficiency. The bills revise and expand the existing urban water management plan requirements to include five-year drought risk assessments, water shortage contingency plans, and annual water supply/demand assessments. By June 30, 2022, the California State Water Resources Control Board, in conjunction with the California Department of Water Resources, is expected to establish long-term water use standards for indoor residential use, outdoor residential use, water losses, and other uses. Cal Water will also be required to calculate and report on urban water use target by November 1, 2023 and each November 1 thereafter, that compares actual urban water use to the target. Management believes that Cal Water is well positioned to comply with all such regulations.

The following table shows the estimated quantity of water purchased and the percentage of purchased water to total water production in each California operating district that purchased water in 2021. Other than noted below, all other districts receive 100% of their water supply from wells.

The Bear Gulch district obtains a portion of its water supply from surface runoff from the local watershed. The Oroville district in the Sacramento Valley, the Bakersfield district in the San Joaquin Valley, and the Kern River Valley district in the Los Angeles Area purchase water from a surface supply. Surface sources are processed through our water treatment plants before being delivered to the distribution system. The Bakersfield district also purchases treated water as a component of its water supply.

Table of Contents

The Chico, Marysville, Dixon, and Willows districts in the Sacramento Valley, the Salinas Valley Region district in the Salinas Valley, the Selma and Visalia districts in the San Joaquin Valley, and the TAFB in Solano County obtain their entire supply from wells.

Purchases for the Los Altos, Livermore, Oroville, Redwood Valley, Stockton, and Bakersfield districts are pursuant to long-term contracts expiring on various dates after 2021. The water supplies purchased for the Dominguez, East Los Angeles, Hermosa Redondo, Palos Verdes, and Westlake districts as well as the Hawthorne and Commerce systems are provided by public agencies pursuant to a statutory obligation of continued non-preferential service to purveyors within the agencies' boundaries. Purchases for the Bayshore and Bear Gulch districts are in accordance with long-term contracts with the San Francisco Public Utilities Commission (SFPUC) until June 30, 2034.

Management anticipates water supply contracts will be renewed as they expire though the price of wholesale water purchases is anticipated to increase in the future.

Shown below are wholesaler price rates and increases that became effective in 2021, and estimated wholesaler price rates and percent changes for 2022. In 2021, several districts experienced purchased water rate increases, resulting in the filing of several purchased water offsets.

Seasonal Fluctuations

In California, our customers' consumption pattern of water varies with the weather, in terms of rainfall and temperature. In the WRAM and MCBA design, the CPUC considers the historical pattern in determining the adopted sales and production costs. With a majority of our sales being subject to the WRAM and production costs being covered by the MCBA, fluctuations in financial results have been minimized. However, cash flows from operations and short-term borrowings on our credit facilities can be significantly impacted by seasonal fluctuations including recovery of the WRAM and MCBA.

Our water business is seasonal in nature. Weather conditions can have a material effect on customer usage. Customer demand for water generally is lower during the cooler and rainy winter months. Demand increases in the spring when warmer weather returns and the rains end, and customers use more water for outdoor purposes such as landscape irrigation. Warm temperatures during the generally dry summer months result in increased demand. Water usage declines during the late fall as temperatures decrease and the rainy season begins. During years in which precipitation is especially heavy or extends beyond the spring into the early summer, customer demand can decrease from historic normal levels, generally due to reduced outdoor water usage. Likewise, an early start to the rainy season during the fall can cause a decline in customer usage. As a result, seasonality of water usage has a significant impact on our cash flows from operations and borrowing on our short-term facilities.

Utility Plant Construction

We have continually extended, enlarged, and replaced our facilities as required to meet increasing demands and to maintain the water systems. We obtain construction financing using funds from operations, long-term financing, advances for construction and contributions in aid of construction that are funded by developers. Advances for construction are cash deposits from developers for construction of water facilities or water facilities deeded from developers. These advances are generally refundable without interest over a period of 40 years in equal annual payment amounts and developer-installed facilities are exempt from corporate income taxes. Contributions in aid of construction consist of nonrefundable cash deposits or facilities transferred from developers, primarily for fire protection and relocation projects. We cannot control the amounts received from developers. This amount fluctuates from year-to-year as the level of construction activity carried on by developers varies. This activity is impacted by the demand for housing, commercial development, and general business conditions, including interest rates.

See Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" for additional information.

Energy Reliability

We continue to use power efficiently to minimize the power expenses passed on to our customers, and maintain backup power systems to continue water service to our customers if the power companies' supplies are interrupted. If future legislation limits emissions from the power generation process, our cost of power may increase. Any increase in the cost of power will be passed along to our California customers through the MCBA or included in our cost of service paid by our customers as requested in our GRC filings. Many of our well sites are equipped with emergency electric generators designed to produce electricity to keep the wells operating during power outages. Storage tanks also provide customers with water during blackout periods.

During 2021 and 2020, we leased additional emergency generators to respond to potential PSPSs, an electric utility operating paradigm approved by the CPUC.

Security at Company Facilities

Due to terrorism and other risks, we have heightened security at our facilities and have taken added precautions to protect our employees and the water delivered to customers. In 2002, federal legislation was enacted that resulted in new regulations concerning security of water facilities, including submitting vulnerability assessment studies to the federal government. We have complied with regulations issued by the U.S. Environmental Protection Agency (EPA) pursuant to federal legislation concerning vulnerability assessments and have made filings to the EPA as required. In addition, communication plans have been developed as a component of our procedures. While we do not make public comments on our security programs, we have been in contact with federal, state, and local law enforcement agencies to coordinate and improve our water delivery systems' security.

In accordance with the 2018 America’s Water Infrastructure Act (AWIA), we are required to conduct additional risk and resilience assessments and develop emergency response plans for each of our water systems. These assessments and plans include natural hazards as well as malevolent acts. The first such assessments were filed in 2020. They will be reviewed and resubmitted every five years.

Table of Contents

While we do not make public comments on our security programs, we have been in contact with federal, state, and local law enforcement agencies to coordinate and improve our water delivery systems' security

Competition and Condemnation

Our principal operations are regulated by the Commission of each state. Under state laws, no privately owned public utility may compete within any service territory that we already serve without first obtaining a certificate of public convenience and necessity from the applicable Commission. Issuance of such a certificate would only be made upon finding that our service is deficient. To management's knowledge, no application to provide service to an area served by us has been made.

State law in California provides that whenever a public agency constructs facilities to extend a utility system into the service area of a privately owned public utility, such an act constitutes the taking of property and requires reimbursement to the utility for its loss. State law in Washington and other states recognize chartered service areas but do not have specific statutes. State statutes allow municipalities, water districts and other public agencies to own and operate water systems. These agencies are empowered to condemn properties already operated by privately owned public utilities. The agencies are also authorized to issue bonds, including revenue bonds, for the purpose of acquiring or constructing water systems. However, if a public agency were to acquire utility property by eminent domain action, the utility would be entitled to just compensation for its loss. In Washington, annexation was approved in February 2008 for property served by us on Orcas Island; however, we continue to serve the customers in the annexed area and do not expect the annexation to affect our operations. To management's knowledge, other than the Orcas Island property, no municipality, water district, or other public agency is contemplating or has any action pending to acquire or condemn any of our systems.

Government Regulations

Our water and wastewater services are governed by various federal and state environmental protection, health and safety laws, and regulations. These provisions establish criteria for drinking water and for discharges of water, wastewater, and airborne substances. The EPA, state water quality regulators, and other state regulatory authorities promulgate numerous nationally and locally applicable standards, including maximum contaminant levels (MCLs) for drinking water. We believe we are currently in compliance with all of the MCLs promulgated to date.

Environmental Matters

Our operations are subject to environmental regulation by various governmental authorities. Environmental health and safety programs have been designed to provide compliance with water discharge regulations, underground and above-ground fuel storage tank regulations, hazardous materials management plans, hazardous waste regulations, air quality permitting requirements, wastewater discharge limitations, and employee safety issues related to hazardous materials. In addition, we actively investigate alternative technologies for meeting environmental regulations and continue the traditional practices of meeting environmental regulations.

For a description of the material effects that compliance with environmental regulations may have on us, see Item 1A. "Risk Factors—Risks Related to Our Regulatory Environment." We expect environmental regulation to increase, resulting in higher operating costs in the future, and there can be no assurance that the Commissions would approve rate increases to enable us to recover these additional compliance costs.

Quality of Water Supply

Our operating practices are designed to produce potable water in accordance with accepted water utility practices. Water entering the distribution systems from surface sources is treated in compliance with federal and state Safe Drinking Water Act (SDWA) standards. Most well supplies are chlorinated or chloraminated for disinfection. Water samples from each water system are analyzed on a regular, scheduled basis in compliance with regulatory requirements. We operate a state-certified water quality laboratory at the San Jose Customer Support Services Office that provides testing for most of our California operations. Certain tests in California are contracted with independent certified labs qualified under the Environmental Laboratory Accreditation Program. Local independent state certified labs provide water sample testing for the Washington, New Mexico and Hawaii operations.

In recent years, federal and state water quality regulations have resulted in increased water sampling requirements. The SDWA continues to be used to monitor and regulate additional potential contaminants to address public health concerns. The State of California has continued to adopt new water quality regulations, which may be in addition to those adopted by the EPA. We monitor water quality standard changes and upgrade our treatment capabilities to maintain compliance with the various regulations.

Table of Contents

Impact of Climate Change Legislation and Regulation

Our operations depend on power provided by other public utilities and, in emergencies, power generated by our portable and fixed generators. If future legislation limits emissions from the power generation process, our cost of power may increase. Any increase in the cost of power will be passed along to our California customers through the MCBA or included in our cost of service paid by our customers as requested in our GRC filings.

We maintain a fleet of vehicles to provide service to our customers, including a number of heavy-duty diesel vehicles that were retrofitted to meet California emission standards. If future legislation further affects the cost to operate the fleet or the fleet acquisition cost in order to meet certain emission standards, it will increase our cost of service and our rate base. Any increase in fleet operating costs associated with meeting emission standards will be included in our cost of service paid by our customers as requested in our GRC filings. While recovery of these costs is not guaranteed, we would expect recovery in the regulatory process.

Under the California Environmental Quality Act (CEQA), all capital projects of a certain type (primarily wells, tanks, major pipelines, and treatment facilities) require mitigation of greenhouse gas emissions. The cost to prepare the CEQA documentation and permit will be included in our capital cost and added to our rate base, which will be requested to be paid for by our customers. Any increase in the operating cost of the facilities will also be included in our cost of service paid by our customers as requested in our GRC filings. While recovery of these costs is not guaranteed, we would expect recovery in the regulatory process.

Cap and trade regulations were implemented in 2012 with the goal of reducing emissions to 1990 levels by the year 2020. These regulations have not affected water utilities at this time. In the future, if we are required to comply with these regulations, any increase in operating costs associated with meeting these standards will be included in our cost of service paid by our customers as requested in our GRC filings. While recovery of these costs is not guaranteed, we would expect recovery in the regulatory process.

Human Capital Resources

We believe our employees are our most important resources and are critical to our continued success. We focus significant attention on attracting and retaining talented and experienced individuals to manage and support our operations. We offer our employees a broad range of company-paid benefits, and we believe our compensation package and benefits are competitive with others in our industry. Additional information about our employee benefit plans is included in Note 12.

We are committed to hiring, developing and supporting a diverse and inclusive workplace. Our employees are expected to exhibit and promote honest, ethical, and respectful conduct in the workplace. All of our employees must adhere to a code of conduct that sets standards for appropriate behavior and includes required internal training on preventing, identifying, reporting and stopping any type of discrimination.

Employee health and safety in the workplace is one of the Company’s core values. Safety efforts are led by the Corporate Safety Committee and supported by safety committees that operate at the local level. Hazards in the workplace are actively identified and management tracks incidents so remedial actions can be taken to improve workplace safety. The COVID-19 pandemic has underscored for us the importance of keeping our employees safe and healthy. In response to the pandemic, the Company has taken actions aligned with the World Health Organization and the Centers for Disease Control and Prevention to protect its workforce so they can more safely and effectively perform their work.

Our management team supports a culture of developing future leaders from our existing workforce, enabling us to promote from within for many leadership positions. We believe this provides long-term focus and continuity to our operations while also providing opportunities for the growth and advancement of our employees. Our focus on retention is evident in the length of service of our management team. The average tenure of our management team is over 16 years.

Employee levels are managed to align with the pace of business and management believes it has sufficient human capital to operate its business successfully. Management believes that the Company's employee relations are favorable. At December 31, 2021, we had 1,182 employees, including 1,047 at Cal Water, 74 at Washington Water, 47 at Hawaii Water, 14 at New Mexico Water, and no employees at Texas Water. In California, the Utility Workers Union of America (UWUA), AFL-CIO represents our non-exempt field, customer service, and non-confidential clerical employees. The International Federation of Professional and Technical Engineers (IFPTE), AFL-CIO represents our professional and technical engineering and water quality laboratory employees.

Table of Contents

As of December 31, 2021, we had 642 employees represented by the UWUA and 85 employees represented by the IFPTE. In 2021, we reached a six-year agreement with both unions on a new contract that runs from May 14, 2021 (UWUA) and October 4, 2021 (IFPTE) through February 28, 2027. The agreement continues to provide our employees with a market competitive pay and benefits package.

Employees at Hawaii Water, Washington Water, and New Mexico Water are not represented by a labor union.

Item 1A. Risk Factors.

In evaluating our business, you should carefully consider the following discussion of material risks, events and uncertainties that make an investment in us speculative or risky in addition to the other information in this Annual Report on Form 10-K. A manifestation of any of the following risks and uncertainties could, in circumstances we may or may not be able to accurately predict, materially and adversely affect our business, growth, reputation, prospects, operating and financial results, financial condition, cash flows, liquidity, and stock price. We note these factors for investors as permitted by the Private Securities Litigation Reform Act of 1995. It is not possible to predict or identify all such factors; our operations could also be affected by factors, events or uncertainties that are not presently known to us or that we currently do not consider to present significant risks to our operations. Therefore, you should not consider the following risks to be a complete statement of all the potential risks or uncertainties that we face.

Risks Related to Our Regulatory Environment

Our business is heavily regulated by state and federal regulatory agencies and our financial viability depends upon our ability to recover costs from our customers through rates that must be approved by state public utility commissions.

California Water Service Company, New Mexico Water Service Company, Washington Water Service Company, and Hawaii Water Service Company, Inc. are regulated public utilities, which provide water and water-related service to our customers. Additionally, Hawaii Water Service Company, Inc. and TWSC, Inc. own in whole or in part other companies, which are regulated public utilities. The rates that we charge our water customers are subject to the jurisdiction of the regulatory commissions in the states in which we operate. These Commissions may set water and water-related rates for each operating district independently because the systems are not interconnected. The Commissions authorize us to charge rates that they consider sufficient to recover normal operating expenses, to provide funds for adding new or replacing water infrastructure, and to allow us to earn what the Commissions consider to be a fair and reasonable return on invested capital.

Table of Contents

Our revenues and consequently our ability to meet our financial objectives are dependent upon the rates we are authorized to charge our customers by the Commissions and our ability to recover our costs in these rates. Our management uses forecasts, models and estimates in order to set rates that will provide a fair and reasonable return on our invested capital. While our rates must be approved by the Commissions, no assurance can be given that our forecasts, models and estimates will be correct or that the Commissions will agree with our forecasts, models and estimates. If our rates are set too low, our revenues may be insufficient to cover our operating expenses, capital expenditure requirements and desired dividend levels.

We periodically file rate increase applications with the Commissions. The ensuing administrative and hearing process may be lengthy and costly. The decisions of the Commissions are beyond our control and we can provide no assurances that our rate increase requests will be granted by the Commissions. Even if approved, there is no guarantee that approval will be given in a timely manner or at a sufficient level to cover our expenses and provide a reasonable return on our investment. If the rate increase decisions are delayed, our earnings may be adversely affected. For example, the CPUC did not issue its decision on our 2018 GRC until December 2020, approximately one year later than expected, which caused some financial and operating uncertainty for the Company until that time.

Our evaluation of the probability of recovery of regulatory assets is subject to adjustment by regulatory agencies and any such adjustment could adversely affect our results of operations and financial condition.

Regulatory decisions may also affect prospective revenues and earnings, affect the timing of the recognition of revenues and expenses and may overturn past decisions used in determining our revenues and expenses. Our management continually evaluates the anticipated recovery of regulatory assets and revenues subject to refund and provides for allowances and/or reserves as deemed necessary. Current accounting procedures allow us to defer certain costs if we believe it is probable that we will be allowed to recover those costs through future rate increases. If the Commissions determined that a portion of our assets were not recoverable in customer rates, we may suffer an asset impairment, which would require a write down in such asset's valuation that would be recorded through operations.

If our assessment as to the probability of recovery through the ratemaking process were incorrect, the associated regulatory asset would be adjusted to reflect the change in our assessment or any regulatory disallowances. A change in our evaluation of the probability of recovery of regulatory assets or a regulatory disallowance of all or a portion of our cost could have a material adverse effect on our financial results.

Regulatory agencies may disagree with our valuation and characterization of certain of our assets.

If we determine that assets are no longer used or useful for utility operations, we may remove them from our rate base and subsequently sell those assets with any gain on sales accruing to the stockholders, subject to certain conditions. If the Commissions disagree with our characterization, there is a risk that the Commissions could determine that realized appreciation in property value should be awarded to customers rather than our stockholders.

Changes in laws, rules, and policies of our regulators or operating jurisdictions can significantly affect our business.

Regulatory agencies may change their rules and policies for various reasons, including changes in the local political environment. Regulators are elected by popular vote or are appointed by elected officials, and the results of elections may change the long-established rules and policies of an agency dramatically. For example, in 2020 regulation regarding full decoupling WRAMs changed in California. Since 2008, the CPUC allowed full decoupling WRAMs. However, in 2020, the CPUC precluded companies from proposing full decoupling WRAMs in their next GRC filings. The decision by the CPUC to change its policy will affect our business beginning in 2023.

We rely on policies and regulations promulgated by the various state commissions in order to recover capital expenditures, maintain favorable treatment on gains from the sale of real property, offset certain production and operating costs, recover the cost of debt, maintain an optimal equity structure without over-leveraging, and have financial and operational flexibility to engage in non-regulated operations. If any of the Commissions with jurisdiction over us implements policies and regulations that do not allow us to accomplish some or all of the items listed above, our future operating results may be adversely affected.

In addition, legislatures may repeal, relax or tighten existing laws, or enact new laws that affect the regulatory agencies with jurisdiction over our business or affect our business directly. If changes in existing laws or the implementation of new laws limit our ability to accomplish some of our business objectives, our future operating results may be adversely affected.

Table of Contents

Finally, local jurisdictions may impose new ordinances, laws, fees, and regulations that could increase costs or limit our operations in ways, which affect future operating results. Cities may impose or amend franchise requirements, impose conditions on underground construction or land use, impose various taxes and fees, or restrict our hours for construction, among other things. In the last decade, more cities have imposed excavation moratoria or paving rules, which has required more costly construction than anticipated.

We expect environmental health and safety regulation to increase, resulting in higher operating costs in the future and the potential that the company fails to meet these regulatory standards.

Our water and wastewater services are governed by various federal and state environmental protection, health and safety laws, and regulations. Although we have a rigorous water quality assurance program in place, we cannot guarantee that we will continue to comply with all standards. If we violate any federal or state regulations or laws governing health and safety, we could be subject to substantial fines or otherwise sanctioned, subject to potential civil liability for damages, and our customers' trust in our operations ability could be eroded.

Environmental health and safety laws are complex and change frequently. They tend to become more stringent over time. As new or stricter standards are introduced, they could increase our operating costs. Although we would likely seek permission to recover these costs through rate increases, we can give no assurance that the Commissions would approve rate increases to enable us to recover these additional compliance costs.

We are required to test our water quality for certain chemicals and potential contaminants on a regular basis. If the test results indicate that our water exceeds allowable limits, we may be required either to commence treatment to remove the contaminant or to develop an alternate water source. Either of these results may be costly. Although we would likely seek permission to recover these through rate increases, there can be no assurance that the Commissions would approve rate increases to enable us to recover these additional compliance costs.

Past events in the utility sector, including those in Flint, Michigan and related to Pacific Gas and Electric Company in California, show that failure to meet one or more water quality, environmental, or safety standards can have severe effects on customer trust, reputation, regulatory treatment, or civil and criminal liability.

New and/or more stringent water quality regulations could increase our operating costs.

We are subject to water quality standards set by federal, state, and local authorities that have the power to issue new regulations. Compliance with new regulations that are more stringent than current regulations could increase our operating costs.

In August of 2009, the Office of Environmental Health Hazard Assessment within the California Environmental Protection Agency changed the water quality standard for TCP in our water supply. The new standard requires us to have 0.0007 parts per billion or less of TCP in our California water supply. We have incurred costs associated with the compliance of the new TCP standard and expect to continue to incur costs in the future. In 2018, we received proceeds from a TCP settlement (see note 15 in the Notes to the Consolidated Financial Statements) that has been used to offset some of the compliance costs that we have incurred. Although we would likely seek permission to these additional costs through the GRC process, we can give no assurance that the CPUC would approve the recovery of these additional compliance costs.

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are two water contaminants of emerging concern. Although a water quality standard has yet to be set by federal or state regulators, preliminary testing, and guidance from the California Environmental Protection Agency has affected our operations of some wells in California. We expect that a water quality standard will be set in the future and that we will incur costs to comply with the water quality standard. Cal Water has requested and been approved to use a memorandum account to track the incremental compliance costs in the future and we would likely seek permission to recover additional costs of compliance through rate increases; however, we can give no assurance that the CPUC would approve rate increases to enable us to recover these additional compliance costs.

Legislation and regulation designed to mitigate or adapt to climate change may affect our operations.

Future legislation or regulation regarding climate change may restrict our operations or impose new costs on our business. Our operations depend on power provided by other public utilities and, in emergencies, power generated by our portable and fixed generators. If future legislation or regulation limits emissions from the power generation process, our cost of power may increase. Any increase in the cost of power will be passed along to our California customers through the MCBA or included in our cost of service paid by our customers as requested in our GRC filings in California.

Table of Contents

We have been and may in the future be party to environmental and product-related lawsuits, which could result in us paying damages not covered by insurance.

We have been and may be in the future, party to water contamination lawsuits, which may not be fully covered by insurance.

The number of environmental and product-related lawsuits against other water utilities has increased in frequency in recent years. If we are subject to additional environmental or product-related lawsuits, we might incur significant legal costs and it is uncertain whether we would be able to recover the legal costs from customers or other third parties. In addition, if current California law regarding CPUC's preemptive jurisdiction over regulated public utilities for claims about compliance with California Department of Health Services and United States EPA water quality standards changes, our legal exposure may be significantly increased.

Risks Related to Our Business Operations

The Ongoing COVID-19 Pandemic May Adversely Affect Our Operations

Although the COVID-19 pandemic did not have a significant impact on our business in 2021, we are unable to accurately predict the full impact that the ongoing COVID-19 pandemic will have on our business, results of operations, financial condition or liquidity due to numerous uncertainties, including the duration and severity of the outbreak, potential resurgence and /or mutations of the virus, and the development, distribution and public acceptance of treatments and vaccines. As an “essential business” during times of emergencies pursuant to the U.S. Critical Infrastructures Protection Act of 2001, we are working to continue to provide high quality water and wastewater services to our two million customers. During the course of 2021, shelter-in-place and social distancing ordinances of varying durations and scope were in effect in all of the states in which we operate. Such governmental orders resulted in temporary closures of non-essential businesses and self-quarantining on non-essential workers. If we close any of our facilities due to a COVID-19 outbreak or if a critical number of our employees become too ill to work, our business operations could be materially adversely affected in a rapid manner. In addition, the COVID-19 pandemic has resulted in significant disruption to economic activity and the states in which the Company operates have experienced significant increases in unemployment claims and business closures. The Company has also ceased all shutoffs for nonpayment during the pandemic. If a significant number of customers are unable to pay utility bills for an extended period of time our business, results of operations, financial condition or liquidity may be materially adversely affected.

We may be at risk for litigation under the principle of inverse condemnation for activities in the normal course of business, which have a damaging effect on private property.

The California constitution may allow compensation to property owners for a public utility taking or damaging private property, even when damage occurs through no fault of the utility and regardless of whether the damage could be foreseen by the utility. As a result, this doctrine, which is known as inverse condemnation and is routinely invoked in California, imposes strict liability for damages, including legal fees, because of the design, construction, and maintenance of utility facilities. In addition to claims that our water or wastewater systems damaged property, Cal Water could be sued under inverse condemnation if its facilities or operations damage private property, or if it is unable to timely deliver sufficient quantities of water for firefighting because of system capacity limitations or water supply disruptions, including as a result of action taken by an electric utility pursuant to a PSPS program or other loss of power. Although the imposition of liability is premised on the assumption that utilities have the ability to recover these costs from their customers, there is no assurance that the CPUC would allow Cal Water to recover any such damage awards from customers. For example, in December 2017, the CPUC denied recovery of costs that San Diego Gas & Electric Company incurred because of inverse condemnation, holding that the inverse condemnation principles of strict liability are not relevant to the CPUC’s prudent manager standard.

The effects of natural disasters, attacks by third parties, pandemics, or poor water quality or contamination to our water supply may result in disruption in our services and litigation, which could adversely affect our business, operating results and financial condition.

We operate in areas that are prone to earthquakes, fires, mudslides and other natural disasters. A significant seismic event or other natural disaster in California where our operations are concentrated could adversely affect our ability to deliver water and adversely affect our costs of operations. A major disaster could damage or destroy substantial capital assets. The CPUC has historically allowed utilities to establish a catastrophic event memorandum account as another possible mechanism to recover costs. However, we can give no assurance that the CPUC or any other commission would allow any such cost recovery mechanism in the future.

Table of Contents

Our water supplies are subject to contamination, including contamination from the development of naturally-occurring compounds, chemicals in groundwater systems, pollution resulting from fabricated sources, such as TCP, seawater incursion and possible third-party attacks, including physical attacks, terrorist attacks, and cyber-attacks. If our water supply is contaminated, we may have to interrupt the use of that water supply until we are able to substitute the flow of water from an uncontaminated water source. In addition, we may incur significant costs in order to treat the contaminated source through expansion of our current treatment facilities, or development of new treatment methods. If we are unable to substitute water supply from an uncontaminated water source, or if we are unable to adequately treat the contaminated water source in a cost-effective manner, there may be an adverse effect on our revenues, operating results and financial condition. The costs we incur to decontaminate a water source or an underground water system could be significant and may not be recoverable in rates. We could also be held liable for consequences arising out of human exposure to hazardous substances in our water supplies or other environmental damage. For example, private plaintiffs have the right to bring personal injury or other toxic tort claims arising from the presence of hazardous substances in our drinking water supplies. Our insurance policies may not be sufficient to cover the costs of these claims.

We have taken steps to increase security measures at our facilities and heighten employee awareness of threats to our water supply, to protect against third-party attacks, including physical attacks, terrorist attacks, and cyber-attacks. We have also tightened our security measures regarding the delivery and handling of certain chemicals used in our business. We have and will continue to bear increased costs for security precautions to protect our facilities, operations, and supplies. These costs may be significant. Despite these tightened security measures, we may not be in a position to control the outcome of third-party attacks should they occur.

We depend upon our skilled and trained workforce to ensure water delivery. Were a pandemic to occur, we can give no assurance that we would be able to maintain sufficient human resources to ensure uninterrupted service in all of the districts that we serve.

If any of these catastrophic events were to occur, we can give no assurance that our emergency preparedness plans would be adequate and that we would respond effectively, which could result in public or employee harm.

Failure of critical elements of our infrastructure could result in interruption of service, damage to others, or injuries, and could adversely affect our business, operating results and financial condition.

We own physical infrastructure, which was installed over a long period of time, both underground and above-ground. This infrastructure is subject to potential failure due to age, operating conditions, or other unknown factors. Failure of any of our facilities could cause flooding, loss of service to our customers, contamination from chemicals we use in operations, or other damages.

We operate a dam. If the dam were to fail for any reason, we would lose a water supply and flooding likely would occur. Whether or not we were responsible for the dam's failure, we could be sued. We can give no assurance that we would be able to defend such a suit successfully.

We operate several water and wastewater treatment plants. If a major failure of these facilities were to occur, we would have an interruption in service, potential flooding, and could release potentially harmful material into the environment.

We operate over 7,000 miles of underground pipeline. Some failures of underground pipelines could release chemicals into the environment, which have a negative impact on sensitive habitats.

We rely on our information technology ("IT") and a number of complex business systems to assist with the management of our business and customer and supplier relationships, and a disruption of these systems could adversely affect our business.

Our IT systems are an integral part of our business, and a serious disruption of our IT systems could significantly limit our ability to manage and operate our business efficiently, which, in turn, could cause our business and competitive position to suffer and adversely affect our results of operations. We depend on our IT systems to bill customers, process orders, provide customer service, manage construction projects, manage our financial records, track assets, remotely monitor certain of our plants and facilities and manage human resources, inventory and accounts receivable collections. Our IT systems also enable us to purchase products from our suppliers and bill customers on a timely basis, maintain cost-effective operations, and provide service to our customers. Some of our mission and business critical IT systems are older, such as our Supervisory Control and Data Acquisition system. The steps we have taken to protect our IT systems may be insufficient to protect them from damage or interruption from:

•power loss, computer systems failures, and internet, telecommunications or data network failures;

•operator negligence or improper operation by, or supervision of, employees;

Table of Contents

•physical and electronic loss of customer data due to security breaches, cyber-attacks, misappropriation and similar events;

•computer viruses;

•intentional security breaches, hacking, denial of services actions, misappropriation of data, and similar events, including intentional cyber security breaches aimed at disrupting and interfering with water treatment processes; and

•earthquakes, floods, fires, mudslides and other natural disasters or physical attacks.

These events may result in physical and/or electronic loss of customer or financial data, security breaches, misappropriation and other adverse consequences, including liability or regulatory penalties under data privacy laws and regulations. In addition, the lack of redundancy for certain of our IT systems, including billing systems, could exacerbate the impact of any of these events on us.

In addition, we may not be successful in developing or acquiring technology that is competitive and responsive to the needs of our business, and we might lack sufficient resources to make the necessary upgrades or replacements of our outdated existing technology to allow us to continue to operate at our current level of efficiency.

The adequacy of our water supplies depends upon a variety of factors beyond our control. Interruption in the water supply may adversely affect our reputation and earnings.

We depend on an adequate water supply to meet the present and future needs of our customers. Whether we have an adequate supply varies depending upon a variety of factors, many of which are partially or completely beyond our control, including:

•the amount of rainfall;

•the amount of water stored in reservoirs;

•underground water supply from which well water is pumped;

•availability from water wholesalers;

•changes in the amount of water used by our customers;

•water quality and availability of appropriate treatment technology;

•legal limitations on water use such as rationing restrictions during a drought;

•changes in prevailing weather patterns and climate; and

•population growth.

We purchase our water supply from various governmental agencies and others. Water supply availability may be affected by weather conditions, funding and other political and environmental considerations. In addition, our ability to use surface water is subject to regulations regarding water quality and volume limitations. If new regulations are imposed or existing regulations are changed or given new interpretations, the availability of surface water may be materially reduced. A reduction in surface water could result in the need to procure more costly water from other sources, thereby increasing our water production costs and adversely affecting our operating results if not recovered in rates on a timely basis.

We have entered into long-term water supply agreements, which commit us to making certain minimum payments whether or not we purchase any water. Therefore, if demand were insufficient to use our required purchases we would have to pay for water we did not receive.

From time to time, we enter into water supply agreements with third parties and our business is dependent upon such agreements in order to meet regional demand. For example, we have entered into a water supply contract with the SFPUC that expires on June 30, 2034. We can give no assurance that the SFPUC, or any of the other parties from whom we purchase water, will renew our contracts upon expiration, or that we will not be subject to significant price increases under any such renewed contracts.

The parties from whom we purchase water maintain significant infrastructure and systems to deliver water to us. Maintenance of these facilities is beyond our control. If these facilities are not adequately maintained or if these parties otherwise default on their obligations to supply water to us, we may not have adequate water supplies to meet our customers' needs.

Table of Contents

If we are unable to access adequate water supplies, we may be unable to satisfy all customer demand, which could result in rationing. Rationing may have an adverse effect on cash flow from operations. We can make no guarantee that we will always have access to an adequate supply of water that will meet all required quality standards. Water shortages may affect us in a variety of ways. For example, shortages could:

•adversely affect our supply mix by causing us to rely on more expensive purchased water;

•adversely affect operating costs;

•increase the risk of contamination to our systems due to our inability to maintain sufficient pressure; and

•increase capital expenditures for building pipelines to connect to alternative sources of supply, new wells to replace those that are no longer in service or are otherwise inadequate to meet the needs of our customers and reservoirs and other facilities to conserve or reclaim water.

We may or may not be able to recover increased operating and construction costs on a timely basis, or at all, for our regulated systems through the ratemaking process. Although we can give no assurance, we may be able to recover certain of these costs from third parties that may be responsible, or potentially responsible, for groundwater contamination.

Our water supplies and other aspects of our operations may be affected by climate change.

There is strong scientific consensus that human activity including carbon and methane emissions is impacting many planetary systems such as the heat-trapping capacity of the atmosphere; ocean temperature, circulation, acidity, and volume; weather patterns including the severity and frequency of severe weather events; ambient temperatures; and planetary ice cover. Because scientific investigations have been focused globally, there is tremendous uncertainty over the timing, extent, and types of impacts global climate change may have on our service areas and in our water supplies. Moreover, studies of tree ring data show long periods of drought conditions have occurred prior to significant human impacts in California and prior to our operation. Finally, in the last fifty years, California has experienced at least three severe multi-year droughts. Thus, we plan for water reliability and water shortages including projected and potential climate change risks in our water supply planning activities. Immediate physical risks could affect our operations and intensify over time as climate change worsens. More frequent flooding, wildfires, sea level rise, rising groundwater, and uneven ground level sinking could damage our assets, including pressurized mains, wells, treatment facilities, and other infrastructure. Wildfires and changes in rainfall may also affect water quality, and both higher temperatures and wildfires can pose risks to employee safety. Farther into the mid-century and late-century horizon, temperature increases may cause declines in snowpack storage, and droughts could decrease surface water supply availability and groundwater recharge while causing increased outdoor demands.

Additional climate-related risks may influence our approach as we support the transition to a low-carbon economy. Transition risks include changes in the market and consumer demands, such as differences in generational behaviors, shifts in population locations due to the pandemic and different weather patterns, and variations in water needs and customer groups. Regulatory risks, such as emission trading systems and carbon taxes, may also financially affect our business. Additionally, federal and state regulations present requirements for managing water supplies and limiting impacts on local wildlife, while regional plans and legislation may directly affect how we address water issues.

We also periodically review the climate change plans of our wholesalers to determine whether alternative supplies may be necessary in the future. However, we can give no assurance that replacement water supplies will be available at a reasonable cost or a cost acceptable to our customers and Commissions.

Natural disasters, climate change, and other factors may change the population in our service areas.

In the event that some outside factor such as a wildfire, flood, changed climate pattern, actual or threatened public health emergency, or change in the local economy reduces or eliminates our customer base in a service area, we could face unrecoverable costs. In those circumstances, the remaining customers might not be able to pay for the operating costs or capital costs of the water system. The company may not be able to recover capital costs of property that is no longer used and useful in utility service. Although we would likely seek permission to recover these costs through rate increases on remaining customers or in statewide rates, we can give no assurance that the Commissions would approve rate increases to enable us to recover these costs.

Wastewater operations entail significant risks.

Wastewater collection and treatment involve many risks associated with damage to the environment, and we anticipate that wastewater collection and treatment will become an increasing significant part of our business. If collection or treatment systems fail or do not operate properly, untreated or partially treated wastewater could discharge onto property or into nearby streams and rivers, causing property damage or injury to aquatic life, or even human life. Our results of operations and financial condition could be materially and adversely affected by liabilities resulting from such damage.

Demand for our water is subject to various factors and is affected by seasonal fluctuations.

Demand for our water during the warmer, dry months is generally greater than during cooler or rainy months due primarily to additional requirements for water in connection with irrigation systems, swimming pools, cooling systems and other outside water use. Throughout the year, and particularly during typically warmer months, demand will vary with temperature and rainfall levels. If temperatures during the typically warmer months are cooler than normal, or if there is more rainfall than normal, the demand for our water may decrease. Under the WRAM mechanism, lower water usage in our California operations affects our cash flows in the year of usage, but results in higher cash flows in the following years.

In addition, governmental restrictions on water usage during drought conditions may result in a decreased demand for our water, even if our water reserves are sufficient to serve our customers during these drought conditions. The Commissions may not allow surcharges to collect lost revenues caused by customers' conservation during a drought. Regardless of whether we may surcharge our customers during a conservation period, they may use less water even after a drought has passed because of conservation patterns developed during the drought. Furthermore, our customers may wish to use recycled water as a substitute for potable water. If rights are granted to others to serve our customers recycled water, there will likely be a decrease in demand for our water.

Finally, changes in prevailing weather patterns due to climate change may affect customer demand. If increased ambient temperatures affect our service areas, water used for irrigation and cooling may increase. If rainfall patterns change, our customers may change their patterns of water use including the amount of outdoor irrigation and the type of landscape they install. Government agencies may also mandate changes to customer irrigation or landscape patterns in response to changes in weather and climate.

Changes in water supply costs affect our operations.

The cost to obtain water for delivery to our customers varies depending on the sources of supply, wholesale suppliers' prices, the quality of water required to be treated and the quantity of water produced to fulfill customer water demand. Our source of supply varies among our operating districts. Certain districts obtain all of their supply from wells; some districts purchase all of the supply from wholesale suppliers; and other districts obtain the supply from a combination of wells and wholesale suppliers. A small portion of supply comes from surface sources and is processed through Company-owned water treatment plants. On average, slightly more than half of the water we deliver to our customers is pumped from wells or received from a surface supply with the remainder purchased from wholesale suppliers. Water purchased from suppliers usually costs us more than surface supplied or well pumped water. The cost of purchased water for delivery to customers represented 33.9% and 35.0% of our total operating costs in 2021 and 2020, respectively. Water purchased from suppliers will require renewal of our contracts upon expiration and may result in significant price increases under any such renewed contracts.

Wholesale water suppliers may increase their prices for water delivered to us based on factors that affect their operating costs. Purchased water rate increases are beyond our control. In California, effective July 1, 2008, our ability to recover increases in the cost of purchased water changed with the adoption of the MCBA. With this change, actual purchased water costs are compared to authorized purchased water costs, with variances netted against the variances in purchased power, pump tax, and metered revenue, being recorded to revenue. The balance in the MCBA will be collected in the future by billing the net WRAM and MCBA accounts receivable balances over 12, 18, and 18+ month periods, which may have a short-term negative impact on cash flow.

Dependency upon adequate supply of electricity, certain chemicals, and third-party suppliers of parts and skilled labor could adversely affect our results of operations.

Purchased electrical power is required to operate the wells and pumps needed to supply water to our customers. Although there are back-up power generators to operate a number of wells and pumps in emergencies, an extended interruption in power could affect the ability to supply water. In the past, California has been subject to rolling power blackouts due to insufficient power supplies. There is no assurance we will not be subject to power blackouts in the future. Additionally, we require sufficient amounts of certain chemicals in order to treat the water we supply. There are multiple sources for these chemicals but an extended interruption of supply could adversely affect our ability to adequately treat our water.

Table of Contents

Purchased power is a significant operating expense. During 2021 and 2020, purchased power expense represented 5.6% and 5.2%, respectively, of our total operating costs. These costs are beyond our control and can change unpredictably and substantially as occurred in California during 2001 when rates paid for electricity increased 48%. As with purchased water, purchased power costs are included in the MCBA. Cash flows between rate filings may be adversely affected until the Commission authorizes a rate change, but earnings will be minimally impacted. Cost of chemicals used in the delivery of water is not an element of the MCBA, and therefore, variances in quantity or cost could affect the results of operations.

We rely on outside contractors to supply us with materials and parts critical to the operation of our systems. Should parts and material become unavailable, or should the cost of necessary supplies rise substantially, it could adversely affect our ability to operate or have financial affects that are not recoverable through a regulatory process.

We also rely on outside contractors to complete large construction projects and provide emergency maintenance services. In the event these contractors are unavailable or cannot meet the demands imposed on them, we may face significantly lengthy interruptions of service or delays in constructing capital projects. We may face additional costs to acquire more resources to complete these activities.

Our business requires significant capital expenditures to replace or improve aging infrastructure that are dependent on our ability to secure appropriate funding. If we are unable to obtain sufficient capital or if the rates at which we borrow increase, there would be a negative impact on our results of operations.

The water utility business is capital-intensive. We invest significant funds to replace or improve aging infrastructure such as property, plant, and equipment. In addition, water shortages may adversely affect us by causing us to rely on more purchased water. This could cause increases in capital expenditures needed to build pipelines to secure alternative water sources. In addition, we require capital to grow our business through acquisitions. We fund our short-term capital requirements from cash received from operations and funds received from developers. We also borrow funds from banks under short-term bank lending arrangements. We seek to meet our long-term capital needs by raising equity through common or preferred stock issues or issuing debt obligations. We cannot give any assurance that these sources will continue to be adequate or that the cost of funds will remain at levels permitting us to earn a reasonable rate of return. In the event we are unable to obtain sufficient capital, our expansion efforts could be curtailed, which may affect our growth and may affect our future results of operations.

Our ability to access the capital markets is affected by the ratings of certain of our debt securities. Standard & Poor's Rating Agency issues a rating on California Water Service Company's ability to repay certain debt obligations. The credit rating agency could downgrade our credit rating based on reviews of our financial performance and projections or upon the occurrence of other events that could affect our business outlook. Lower ratings by the agency could restrict our ability to access equity and debt capital. We can give no assurance that the rating agency will maintain ratings that allow us to borrow under advantageous conditions and at reasonable interest rates. A future downgrade by the agency could also increase our cost of capital by causing potential investors to require a higher interest rate due to a perceived risk related to our ability to repay outstanding debt obligations.

While the majority of our debt is long term at fixed rates, we do have interest rate exposure in our short-term borrowings, which have variable interest rates. We are also subject to interest rate risks on new financings. However, if interest rates were to increase on a long-term basis, our management believes that customer rates would increase accordingly, subject to approval by the appropriate commission. We can give no assurance that the Commission would approve such an increase in customer rates.

We are obligated to comply with specified debt covenants under certain of our loan and debt agreements. Failure to maintain compliance with these covenants could limit future borrowing, and we could face increased borrowing costs, litigation, acceleration of maturity schedules, and cross default issues. Such actions by our creditors could have a material adverse effect on our financial condition and results of operations.

Our inability to access the capital or financial markets could affect our ability to meet our liquidity needs at reasonable cost and our ability to meet long-term commitments. Changes in economic conditions in our markets could affect our customers' ability to pay for water services. Any of these could adversely affect our results of operations, cash flows, and financial condition.

We rely on our current credit facilities to fund short-term liquidity needs if internal funds are not available from operations. Specifically, given the seasonal fluctuations in demand for our water we commonly draw on our credit facilities to meet our cash requirements at times in the year when demand is relatively low. We also may occasionally use letters of credit issued under our revolving credit facilities. Disruptions in the capital and credit markets could adversely affect our ability to draw on our credit facilities. Our access to funds under our credit facilities is dependent on the ability of our banks to meet their funding commitments.

Table of Contents

Many of our customers and suppliers also have exposure to risks that could affect their ability to meet payment and supply commitments. We operate in geographic areas that may be particularly susceptible to declines in the price of real property, which could result in significant declines in demand for our products and services. In the event that any of our significant customers or suppliers, or a significant number of smaller customers and suppliers, are adversely affected by these risks, we may face disruptions in supply, significant reductions in demand for our products and services, inability of customers to pay invoices when due, and other adverse effects that could negatively affect our financial condition, results of operations and/or cash flows.

Our operations and certain contracts for water distribution and treatment depend on the financial capability of state and local governments, and other municipal entities such as water districts. Major disruptions in the financial strength or operations of such entities, such as liquidity limitations, bankruptcy or insolvency, could have an adverse effect on our ability to conduct our business and/or enforce our rights under contracts to which such entities are a party.

We are a holding company that depends on cash flow from our subsidiaries to meet our obligations and to pay dividends on our common stock.

As a holding company, we conduct substantially all of our operations through our subsidiaries and our only significant assets are investments in those subsidiaries. 91.9% of our revenues are derived from the operations of California Water Service Company. As a result, we are dependent on cash flow from our subsidiaries, and California Water Service Company in particular, to meet our obligations and to pay dividends on our common stock.

Our subsidiaries are separate and distinct legal entities and generally have no obligation to pay any amounts due on California Water Service Group's debt or to provide California Water Service Group with funds for dividends. Although there are no contractual or regulatory restrictions on the ability of our subsidiaries to transfer funds to us, the reasonableness of our capital structure is one of the factors considered by state and local regulatory agencies in their ratemaking determinations. Therefore, transfer of funds from our subsidiaries to us for the payment of our obligations or dividends may have an adverse effect on ratemaking determinations. Furthermore, our right to receive cash or other assets upon the liquidation or reorganization of a subsidiary is generally subject to the prior claims of creditors of that subsidiary. If we are unable to obtain funds from our subsidiaries in a timely manner, we may be unable to meet our obligations or pay dividends.

We can make dividend payments only from our surplus (the excess, if any, of our net assets over total paid-in capital) or if there is no surplus, the net profits for the current fiscal year or the fiscal year before which the dividend is declared. In addition, we can pay cash dividends only if after paying those dividends we would be able to pay our liabilities as they become due. Owners of our capital stock cannot force us to pay dividends and dividends will only be paid if and when declared by our board of directors. Our board of directors can elect at any time, and for an indefinite duration, not to declare dividends on our capital stock.

An important element of our growth strategy is the acquisition of water and wastewater systems. Risks associated with potential acquisitions, divestitures or restructurings may adversely affect us.

We may seek to acquire or invest in other companies, technologies, services, or products that complement our business. The execution of our growth strategy may expose us to different risks than those associated with our utility operations. We can give no assurance that we will succeed in finding attractive acquisition candidates or investments, or that we would be able to reach mutually agreeable terms with such parties. In addition, as consolidation becomes more prevalent in the water and wastewater industries, the prices for suitable acquisition candidates may increase to unacceptable levels and limit our ability to grow through acquisitions. If we are unable to find acquisition candidates or investments, our ability to grow may be limited.

Acquisition and investment transactions may result in the issuance of our equity securities that could be dilutive if the acquisition or business opportunity does not develop in accordance with our business plan. They may also result in significant write-offs and an increase in our debt. The occurrence of any of these events could have a material adverse effect on our business, financial condition, and results of operations.

Any of these transactions could involve numerous additional risks, including one or more of the following:

•problems integrating the acquired operations, personnel, technologies, physical and cyber security processes, or products with our existing businesses and products;

•liabilities inherited from the acquired companies' prior business operations;

•diversion of management time and attention from our core business to the acquired business;

•failure to retain key technical, management, sales and other personnel of the acquired business;

•difficulty in retaining relationships with suppliers and customers of the acquired business; and

Table of Contents

•difficulty in obtaining required regulatory approvals.

In addition, the businesses and other assets we acquire may not achieve the sales and profitability expected. The occurrence of one or more of these events may have a material adverse effect on our business. There can be no assurance that we will be successful in overcoming these or any other significant risks encountered.

We may not be able to increase or sustain our recent growth rate, and we may not be able to manage our future growth effectively.

We may be unable to continue to expand our business or manage future growth. To successfully manage our growth and handle the responsibilities of being a public company, we must effectively:

•hire, train, integrate and manage additional qualified engineers for engineering design and construction activities, new business personnel, and financial and information technology personnel;

•retain key management, augment our management team, and retain qualified and certified water and wastewater system operators;

•implement and improve additional and existing administrative, financial and operations systems, procedures and controls;

•expand our technological capabilities; and

•manage multiple relationships with our customers, regulators, suppliers and other third parties.

If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities, satisfy customer requirements, execute our business plan, or respond to competitive pressures.

We have a number of large-volume commercial and industrial customers and a significant decrease in consumption by one or more of these customers could have an adverse effect on our operating results and cash flows.

Our billed revenues and cash flows from operations will decrease if a significant business or industrial customer terminates or materially reduces its use of our water. Approximately $171.1 million, or 22.3%, of our 2021 water utility revenues was derived from business and industrial customers. However, if any of our large business or industrial customers in California reduce or cease its consumption of our water, the affect to net operating income would be minimal to our operations due to the WRAM and MCBA, but could impact our cash flows. In Hawaii, we serve a number of large resorts, which if their water usage was reduced or ceased could have a material impact to our Hawaii operation. The delay between such date and the effective date of the rate relief may be significant and could adversely affect our operating results and cash flows.

Our operating cost and costs of providing services may rise faster than our revenues.

Our ability to increase rates over time is dependent upon approval of such rate increases by the Commissions, or in the case of the City of Hawthorne and the City of Commerce, the City Council, which may be inclined, for political or other reasons, to limit rate increases. However, our costs, which are subject to market conditions and other factors, may increase significantly. The second largest component of our operating costs after water production is made up of salaries and wages. These costs are affected by the local supply and demand for qualified labor. Other large components of our costs are general insurance, workers compensation insurance, employee benefits and health insurance costs. These costs may increase disproportionately to rate increases authorized by the Commissions and may have a material adverse effect on our future results of operations.

Demand for our stock may fluctuate due to circumstances beyond our control.

We believe that stockholders invest in public utility stocks, in part, because they seek reliable dividend payments. If there is an over-supply of stock of public utilities in the market relative to demand by such investors, the trading price of our securities could decrease. Additionally, if interest rates rise above the dividend yield offered by our equity securities, demand for our stock, and consequently its market price, may decrease. A decline in demand for our stock may have a negative impact on our ability to finance capital projects.

Table of Contents

Adverse investment returns and other factors may increase our pension liability and pension funding requirements.

A substantial number of our employees are covered by a defined benefit pension plan. At present, the pension plan is underfunded because our projected pension benefit obligation exceeds the aggregate fair value of plan assets. Under applicable law, we are required to make cash contributions to the extent necessary to comply with minimum funding levels imposed by regulatory requirements. The amount of such required cash contribution is based on an actuarial valuation of the plan. The funded status of the plan can be affected by investment returns on plan assets, discount rates, mortality rates of plan participants, pension reform legislation and a number of other factors. There can be no assurance that the value of our pension plan assets will be sufficient to cover future liabilities. Although we contributed to our pension plan in recent years, it is possible that we could incur a pension liability adjustment, or could be required to make additional cash contributions to our pension plan, which would reduce the cash available for business and other needs.

Labor relations matters could adversely affect our operating results.

At December 31, 2021, 727 of our 1,182 total employees were union employees. Most of our unionized employees are represented by the Utility Workers Union of America, AFL-CIO, except certain engineering and laboratory employees who are represented by the International Federation of Professional and Technical Engineers, AFL-CIO.

We believe our labor relations are good, but in light of rising costs for health care and pensions, our current contract negotiations and those in the future may be difficult. Furthermore, changes in applicable law or regulations could have an adverse effect on management's negotiating position with respect to our currently unionized employees and/or employees that decide to unionize in the future. We are subject to a risk of work stoppages and other labor relations matters as we negotiate with the unions to address these issues, which could affect our results of operations and financial condition. We can give no assurance that issues with our labor forces will be resolved favorably to us in the future or that we will not experience work stoppages.

Our operations are geographically concentrated in California and this lack of diversification may negatively affect our operations.

Although we own facilities in a number of states, over 91.9% of our operations are located in California. As a result, we are largely subject to weather, political, water supply, labor, energy cost, regulatory, and economic risks affecting California.

We are also affected by the real property market in California. In order to grow our business, we may need to acquire additional real estate or rights to use real property owned by third parties, the cost of which tends to be higher and more volatile in California than in other states. The value of our assets in California may decline if there is a decline in the California real estate market that results in a significant decrease in real property values.

Municipalities, water districts and other public agencies may condemn our property by eminent domain action.

State statutes allow municipalities, water districts and other public agencies to own and operate water systems. These agencies are empowered to condemn water systems or real property owned by privately owned public utilities in certain circumstances and in compliance with California and federal law. Additionally, whenever a public agency constructs facilities to extend its utility system into the service area of a privately owned public utility, such an act may constitute the taking of property and require reimbursement to the public utility for its loss. If a public agency were to file an eminent domain lawsuit against us, we would incur substantial attorney’s fees, consultant and expert fees, and other costs in considering a challenge to the right to take our utility property and/or its valuation for just compensation, as well as such fees and costs in any subsequent litigation if necessary. If the public agency prevailed and acquired our utility property, we would be entitled to just compensation for our loss, but we would no longer have access to the condemned property or water system. Neither would we be entitled to any portion of revenue generated from the use of such asset going forward.

General Risk Factors

We depend significantly on the services of the members of our management team, and the departure of any of those persons could cause our operating results to suffer.

Our success depends significantly on the continued individual and collective contributions of our management team. The loss of the services of any member of our management team could have an adverse effect on our business as our management team has knowledge of our industry and customers and would be difficult to replace.

Table of Contents

We retain certain risks not covered by our insurance policies.

We evaluate our risks and insurance coverage annually or more frequently if circumstances dictate. Our evaluation considers the costs, risks, and benefits of retaining versus insuring various risks as well as the availability of certain types of insurance coverage. Furthermore, we are also affected by increases in prices for insurance coverage; in particular, we have been, and will continue to be, affected by rising health insurance costs. Retained risks are associated with deductible limits, partial self-insurance programs, and insurance policy coverage ceilings. If we suffer an uninsured loss, we may be unable to pass all or any portion of the loss on to customers, because our rates are regulated by regulatory commissions. Consequently, uninsured losses may negatively affect our financial condition, liquidity, and results of operations. There can be no assurance that we will not face uninsured losses pertaining to the risks we have retained.

Our enterprise risk management processes may not be effective in identifying and mitigating the risks to which we are subject, or in reducing the potential for losses in connection with such risks.

Our enterprise risk management processes are designed to minimize or mitigate the risks to which we are subject, as well as any losses stemming from such risks. Although we seek to identify, measure, monitor, report, and control our exposure to such risks, and employ a broad and diversified set of risk monitoring and mitigation techniques in the process, those techniques are inherently limited in their ability to anticipate the existence or development of risks that are currently unknown and unanticipated. The ineffectiveness of our enterprise risk management processes in mitigating the impact of known risks or the emergence of previously unknown or unanticipated risks may result in our incurring losses in the future that could adversely affect our financial condition and results of operations.

The accuracy of our judgments and estimates about financial and accounting matters will affect our operating results and financial condition.

We make certain estimates and judgments in preparing our financial statements regarding, among others:

•the useful life of intangible rights;

•the number of years to depreciate certain assets;

•amounts to set aside for uncollectible accounts receivable, inventory obsolescence and uninsured losses;

•our legal exposure and the appropriate accrual for claims, including medical claims and workers' compensation claims;

•future costs and assumptions for pensions and other postretirement benefits;

•regulatory recovery of regulatory assets;

•possible tax uncertainties; and

•projected collections of WRAM and MCBA receivables.

The quality and accuracy of those estimates and judgments will have an impact on our operating results and financial condition.

In addition, we must estimate unbilled revenues and costs as of the end of each accounting period. If our estimates are not accurate, we will be required to make an adjustment in a future period. Accounting rules permit us to use expense balancing accounts and memorandum accounts that include cost changes to us that are different from amounts incorporated into the rates approved by the Commissions. These accounts result in expenses and revenues being recognized in periods other than in which they occurred.

Overview

Net Income Attributable to California Water Service Group

In 2021 and 2020, net income attributable to California Water Service Group was $101.1 million and $96.8 million, respectively. Earnings per diluted common share decreased $0.01 to $1.96 or 0.5% from 2020 to 2021. The $4.3 million increase in net income attributable to California Water Service Group was driven by general rate increases of $14.0 million, a reduction in operating income tax expense of $8.6 million, and a decrease in credit losses of $4.6 million. These positive factors were partially offset by increases in depreciation and amortization expenses of $10.2 million, employee wages of $3.2 million, uninsured loss expense of $1.9 million, property and other taxes of $2.4 million, and financing costs of $1.4 million.

Additionally, certain factors outside the Company's immediate control decreased net income attributable to California Water Service Group, including a $0.5 million reduction in accrued unbilled revenue and $0.5 million decrease in unrealized gain on certain benefit plan investments as compared to the prior year. Seasonal weather patterns and the number of unbilled days are the primary influences of accrued unbilled revenue.

We continue to seek rate relief to recover our operating cost increases and receive reasonable returns on invested capital. We expect to fund our long-term capital needs through a combination of debt, common stock offerings, and cash flow from operations.

During the course of 2021, because of the COVID-19 pandemic, shelter-in-place and social distancing ordinances of varying durations and scope were in effect in all of the states in which we operate. Such governmental public health orders continued to result in temporary closures of non-essential businesses and self-quarantining on non-essential workers. As an “essential business” during times of emergencies pursuant to the U.S. Critical Infrastructures Protection Act of 2001, we are working to continue to provide high quality water and wastewater services to our two million customers. During 2021 and through February 24, 2022, the COVID-19 pandemic has not had a significant impact on our business or operations. We have ceased all shutoffs for non-payment during the pandemic and anticipate this situation will continue until further notice. We are expecting segments of our customer base to continue to experience employment layoffs and businesses to run at less than full capacity, which negatively impact their ability to pay utility bills. We have also incurred costs to promote the health and safety of our employees and facilities.

If we need to close any of our facilities due to outbreaks of COVID-19 or if a critical number of our employees become too ill to work, our business operations could be materially adversely affected in a rapid manner. The impact of the COVID-19 pandemic is fluid and continues to evolve, and therefore, we cannot predict the extent to which our business, results of operations, financial condition, or liquidity will ultimately be impacted.

California Water and Wastewater Arrearages Payment Program

The California Water and Wastewater Arrearages Program was created by the California Legislature to be administered by the State Water Resources Control Board (Water Board) in order to provide relief to community water and wastewater systems for unpaid bills (arrearages) related to the COVID-19 pandemic. The Legislature allocated $985 million in American Rescue Plan Act of 2021 funds to pay down residential and commercial arrearages accrued between March 4, 2020 and June 14, 2021. In response to the Water Board’s survey, Cal Water reported $20.8 million in eligible customer arrearages and program administrative costs. Cal Water received 100% of the requested amount from the program in January 2022. Cal Water will apply these funds to identified past due customer balances during the first quarter of 2022.

Critical Accounting Policies and Estimates

We maintain our accounting records in accordance with accounting principles generally accepted in the United States of America and as directed by the Commissions to which our operations are subject. The process of preparing financial statements requires the use of estimates on the part of management. The estimates used by management are based on historic experience and an understanding of current facts and circumstances. A summary of our significant accounting policies is listed in Note 2 of the Notes to Consolidated Financial Statements. The following sections describe those policies where the level of subjectivity, judgment, and variability of estimates could have a material impact on the financial condition, operating performance, and cash flows of the business.

Revenue Recognition

Revenue from contracts with customers

The Company principally generates operating revenue from contracts with customers by providing regulated water and wastewater services at tariff-rates authorized by the Commissions in the states in which they operate and non-regulated water and wastewater services at rates authorized by contracts with government agencies. Revenue from contracts with customers reflects amounts billed for the volume of consumption at authorized per unit rates, for a service charge, and for other authorized charges.

The Company satisfies its performance obligation to provide water and wastewater services over time as services are rendered. The Company applies the invoice practical expedient and recognizes revenue from contracts with customers in the amount for which the Company has a right to invoice. The Company has a right to invoice for the volume of consumption, for the service charge, and for other authorized charges. The measurement of sales to customers is generally based on the reading of their meters, which occurs on a systematic basis throughout the month.

Contract terms are generally short-term and at will by customers and, as a result, no separate financing component is recognized for the Company's collections from customers, which generally require payment within 30 days of billing. The Company applies judgment, based principally on historical payment experience, in estimating its customers’ ability to pay.

Certain customers are not billed for volumetric consumption, but are instead billed a flat rate at the beginning of each monthly service period. The amount billed is initially deferred and subsequently recognized over the monthly service period, as the performance obligation is satisfied. The deferred revenue balance or contract liability, which is included in "other accrued liabilities" on the consolidated balance sheets, is inconsequential.

Regulatory balancing account revenue

The Company’s ability to recover revenue requirements authorized by the CPUC in its triennial GRC is decoupled from the volume of the sales. Regulatory balancing account revenue is revenue related to rate mechanisms authorized in California by the CPUC, which allow the Company to recover the authorized revenue and are not considered contracts with customers. These mechanisms include the following:

The Water Revenue Adjustment Mechanism (WRAM) allows the Company to recognize the adopted level of volumetric revenues. The variance between adopted volumetric revenues and actual billed volumetric revenues for metered accounts is recorded as regulatory balancing account revenue.

Cost-recovery rates, such as the Modified Cost Balancing Account (MCBA), Conservation Balancing Account (CEBA), Pension Cost Balancing Account (PCBA), and Health Cost Balancing Account (HCBA), provide for recovery of the adopted levels of expenses for purchased water, purchased power, pump taxes, water conservation program costs, pension, and health care. Variances between adopted and actual costs are recorded as regulatory balancing account revenue.

Due to the delay in the resolution of the 2018 GRC, the CPUC authorized Cal Water to track the effect of the delay on customer billings in an interim rates memorandum account (IRMA) effective January 1, 2020. Variances between actual customer billings and those that would have been billed assuming the GRC had been effective January 1, 2020 are recorded as regulatory balancing account revenue. Rates for the 2018 GRC were implemented on February 1, 2021; as a result, Cal Water recorded an IRMA regulatory asset for all of 2020 and for January of 2021.

Each district's WRAM and MCBA regulatory assets and liabilities are allowed to be netted against one another. The Company recognizes regulatory balancing account revenues that have been authorized for rate recovery, are objectively determinable and probable of recovery, and are expected to be collected within 24 months. To the extent that regulatory balancing account revenue is estimated to be collectible beyond 24 months, recognition is deferred.

Regulated Utility Accounting

Because we operate almost exclusively in a regulated business, we are subject to the accounting standards for regulated utilities. The Commissions in the states in which we operate establish rates that are designed to permit the recovery of the cost of service and a return on investment. We capitalize and record regulatory assets for costs that would otherwise be charged to expense if it is probable that the incurred costs will be recovered in future rates. Regulatory assets are amortized over the future periods that the costs are expected to be recovered. If costs expected to be incurred in the future are currently being recovered through rates, we record those expected future costs as regulatory liabilities. In addition, we record regulatory liabilities when the Commissions require a refund to be made to our customers over future periods.

Determining probability requires significant judgment by management and includes, but is not limited to, consideration of testimony presented in regulatory hearings, proposed regulatory decisions, final regulatory orders, and the strength or status of applications for rehearing or state court appeals.

If we determine that a portion of our assets used in utility operations is not recoverable in customer rates, we would be required to recognize the loss of the assets disallowed.

Income Taxes

We account for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. We measure deferred tax assets and liabilities at enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We recognize the effect on the deferred tax assets and liabilities of a change in tax rate in the period that includes the enactment date. We also assess the likelihood that deferred tax assets will be recovered in future taxable income and, to the extent recovery is not probable, a valuation allowance would be recorded. In management's view, a valuation allowance was not required as of December 31, 2021 and December 31, 2020.

We anticipate that future rate actions by the regulatory commissions will reflect revenue requirements for the tax effects of temporary differences recognized, which have previously been passed through to customers. The regulatory commissions have granted the Company permission to reflect the normalization of the tax benefits of the federal accelerated methods and available Investment Tax Credits (ITCs) for all assets placed in service after 1980. ITCs are deferred and amortized over the lives of the related properties for book purposes. The CPUC requires flow through accounting for state deferred taxes.

On December 22, 2017, the U.S. government enacted expansive tax legislation commonly referred to as the TCJA. Among other provisions, the TCJA reduces the federal income tax rate from 35 percent to 21 percent beginning on January 1, 2018 and eliminated bonus depreciation for utilities. The TCJA required the Company to re-measure all existing deferred income tax assets and liabilities to reflect the reduction in the federal tax rate.

During 2021, the Company analyzed its deferred tax balances, tax regulatory asset and tax regulatory liability based on 2018 GRC approved rates. As of December 31, 2021, the unamortized TCJA refund was $91.5 million. The Company continued working with other state regulators to finalize the refund to ensure compliance with federal normalization rules.

Pension and Postretirement Benefits Other Than Pensions (PBOP)

We incur costs associated with our pension and PBOP plans. To measure the expense of these benefits, our management must estimate compensation increases, mortality rates, future health cost increases and discount rates used to value related liabilities and to determine appropriate funding. Different estimates used by our management could result in significant variances in the cost recognized for pension and PBOP plans. The estimates used are based on historical experience, current facts, future expectations, and recommendations from independent advisors and actuaries. We use an investment advisor to provide advice in managing the plan's investments. We anticipate any increases in funding for the pension benefits plans will be recovered in future rate filings, thereby mitigating the financial impact. We believe it is probable that future costs will be recovered in future rates and therefore have recorded a regulatory asset in accordance with generally accepted accounting principles. Changes to the pension benefits actuarial assumptions can significantly affect pension costs, regulatory assets, and liabilities.

In 2020, we changed both the yield curve used to develop the discount rate and the method used to estimate the service and interest cost components of net periodic pension and benefit costs for 2021. The new yield curve used a higher-yielding subset of bonds that we believe will better approximate the rate at which the obligations could be effectively settled, currently. The change in the yield curve led to a decrease of $12.2 million and $1.2 million in net periodic pension cost and net periodic benefit cost, respectively, for 2021. The new method uses the spot rate approach to estimate the service and interest costs by applying the specific spot rates along the yield curve used to determine the benefit obligation to the relevant projected cash outflows. The change in method led to a decrease of $6.2 million and $1.1 million in net periodic pension cost and net periodic benefit cost, respectively, for 2021. This change does not affect the measurement of the projected benefit obligation. We made this change to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows to the corresponding spot rates. We have accounted for this change as a change in accounting estimate and accordingly has accounted for it prospectively. In California, where the majority of our net periodic pension and benefit costs are recorded, a corresponding decrease to balancing account revenue was recorded in 2021 for the changes in yield curve and method as Cal Water has regulatory mechanisms that mitigate changes in net periodic pension and benefits costs. For 2020, the service and interest cost components of net periodic pension and benefit costs were determined using a single-weighted average discount rate.

The following table reflects the sensitivity of pension amounts reported for the year ended December 31, 2021, to changes in actuarial assumptions:


	Increase/(Decrease) in Pension Benefits Actuarial Assumption		Increase/(Decrease) in 2021 Net Periodic Benefit Cost		Increase/(Decrease) in Projected Benefit Obligation as of December 31, 2021

Results of Operations

Operating Revenue

Operating revenue in 2021 was $790.9 million, a decrease of $3.4 million, or 0.4%, over 2020. Operating revenue in 2020 was $794.3 million, an increase of $79.7 million, or 11.2%, over 2019. The sources of changes in operating revenue were:


	2021		2020
	Dollars in millions
Net change due to WRAM, service charges, usage, and other (1)	$	29.7	$	29.2
MCBA revenue (2)	(7.9)		46.8
Other balancing account revenue (3)	(13.5)		(1.0)
Deferral of revenue (4)	(11.7)		4.7
Net change	$	(3.4)	$	79.7

_______________________________________________________________________________

(1)In 2021, the net change due to WRAM, service charges, usage, and other in the above table was mainly driven by rate increases (the components of which are set forth in the table in Rates and Regulation section below), and partially offset by a $0.5 million decrease in accrued unbilled revenue.

(2)MCBA revenue is the variance between adopted water production costs and actual water production costs. In 2021, we recognized $3.8 million of MCBA revenue as compared to $11.7 million in MCBA revenue in 2020, for a decrease of $7.9 million in 2021. The MCBA revenue decrease in 2021 as compared to 2020 resulted from a decrease in actual water production costs relative to adopted water production costs. The actual water production costs decreased relative to adopted water production costs in 2021 as compared to 2020, due to a shift in water production mix from purchased water to well water in certain of our service territories. As required by the MCBA mechanism, the decrease in actual water production costs relative to adopted water production costs in California also decreased operating revenue for the same amount.

(3)The other balancing account revenue consists of the pension, conservation, and health care balancing account revenues. Pension and conservation balancing account revenues are the differences between actual expenses and adopted rate recovery. Health care balancing account revenue is 85% of the difference between actual health care expenses and adopted rate recovery. In 2021, we recognized a reduction to revenue of $6.1 million for these balancing accounts as compared to a net $7.4 million of revenue in 2020. The decrease in revenue was mainly due to a decrease in actual pension and health care expenses relative to adopted in 2021 as compared to 2020, which was partially offset by an increase in actual conservation expenses relative to adopted in 2021 as compared to 2020.

(4)The deferral of revenue consists of amounts that are expected to be collected from customers beyond 24 months following the end of the accounting period in which these revenues were recorded. The deferral decreased in 2021 as compared to 2020 due to an increase in the balancing account revenue expected to be collected beyond 24 months.

Water Production Expenses

Water production expenses, which consist of purchased water, purchased power, and pump taxes, comprise the largest segment of total operating expenses. Water production costs accounted for 41.8% and 42.1%, of total operating costs in 2021 and 2020, respectively. The rates charged for wholesale water supplies, electricity, and pump taxes are established by various public agencies. As such, these rates are beyond our control.

The table below provides the change in water production expenses during the past 2 years:


	2021						2020
	Amount		Change		% Change		Amount		Change		% Change
	Dollars in millions
Purchased water	$	225.0	$	(5.1)	(2.2)	%	$	230.1	$	17.6	8.3	%
Purchased power	37.1		3.1		9.1	%	34.0		2.6		8.3	%
Pump taxes	15.3		2.7		21.4	%	12.6		1.1		9.6	%
Total water production expenses	$	277.4	$	0.7	0.3	%	$	276.7	$	21.3	4.5	%

The principal factors affecting water production expenses are the quantity, price, and source of the water. Generally, water pumped from wells costs less than water purchased from wholesale suppliers.

Table of Contents

The table below provides the amounts, percentage change, and source mix for the respective years:


	2021					2020
	MG	% of Total		% change from prior year		MG	% of Total		% change from prior year
	Millions of gallons (MG)
Source:
Wells	52,520	47.5	%	6.9	%	49,116	44.4	%	7.8	%
Purchased	53,620	48.5	%	(4.2)	%	55,948	50.5	%	4.1	%
Surface	4,379	4.0	%	(22.9)	%	5,678	5.1	%	4.8	%
Total	110,519	100.0	%	(0.2)	%	110,742	100.0	%	5.7	%

Purchased water expenses are affected by changes in quantities purchased, supplier prices, and cost differences between wholesale suppliers. The MCBA mechanism is designed to recover all incurred purchased water expenses.

For 2021, the $5.1 million decrease in purchased water expenses is due to a 4.2% decrease in purchased quantities offset by an overall blended water wholesaler rate increase of 4.6%.

Purchased power expenses are affected by the quantity of water pumped from wells and moved through the distribution system, rates charged by electric utility companies, and rate structures applied to usage during peak and non-peak times of the day or season. In 2021, purchased power expenses increased $3.1 million mainly due to a 6.9% increase in well production.

Changes in climate change regulations could increase the cost of power that in turn would result in an increase in the rates our power suppliers charge us. Any change in pricing of our purchased power expenses in California would be recovered from our customers through the MCBA mechanism. Any change in power costs in other states would be requested to be recovered by the customers in those states. The impact of such regulations is dependent upon the enacted date, the factors that affect our suppliers' cost structure, and their ability to pass the costs to us in their approved tariffs. These items are not known at this time.

Administrative and General Expenses

Administrative and general expenses include payroll related to administrative and general functions, all employee benefits charged to expense accounts, insurance expenses, legal fees, expenses associated with being a public company, and general corporate expenses.

During 2021, administrative and general expense increased $9.6 million, or 8.2%, as compared to 2020. The increase was mainly due to increases in employee wages of $6.2 million, uninsured loss costs of $1.9 million, outside consulting service costs of $1.2 million, and employee healthcare costs of $1.2 million. These cost increases were partially offset by a $1.5 million decrease in employee pension and retiree healthcare benefit costs. Changes in employee pension benefits and employee and retiree medical costs for regulated California operations generally do not affect net income attributable to California Water Service Group, as the Company has been allowed by the California Public Utilities Commission (“CPUC”) to record these costs in balancing accounts for future recovery, creating a corresponding change to revenue.

Other Operations Expenses

The components of other operations expenses include payroll, material and supplies, and contract service costs of operating the regulated water systems, including the costs associated with water transmission and distribution, pumping, water quality, meter reading, billing, operations of district offices, and water conservation programs.

During 2021, other operations expense decreased $9.5 million, or 9.9%, compared to 2020. The decrease was primarily due to reductions of $9.5 million in expenses associated with the deferral of operating revenue, $4.6 million reduction in credit losses, and $2.1 million in employee wages. These were partially offset by increases in wastewater treatment expenses of $1.9 million from recently acquired subsidiaries, customer account expenses of $1.1 million, chemical and carbon filter costs of $0.9 million, and conservation program costs of $0.8 million. Changes in conservation program costs for regulated California operations generally do not affect net income attributable to California Water Service Group, as the Company has been allowed by the California Public Utilities Commission (“CPUC”) to record these costs in balancing accounts for future recovery, creating a corresponding change to revenue.

Table of Contents

Maintenance

Maintenance expenses increased $1.6 million, or 5.7%, in 2021, compared to 2020 due to increased costs for repairs of transmission and distribution mains, reservoirs and tanks, and amortization of reservoir coating projects in accordance with CPUC orders.

Depreciation and Amortization

Depreciation and amortization increased $10.2 million, or 10.4%, in 2021 primarily due to utility plant placed in service in 2020.

Income Taxes

For 2021, income taxes decreased $8.6 million, or 75.5%, to $2.8 million as compared to 2020. The decrease was mainly due to a $9.9 million increase in customer refunds of excess deferred federal income taxes in 2021 as compared to 2020, and was partially offset by a reduction in the tax benefit from the flow-through method of accounting for “repairs” deductions on state corporate income tax filings. The Company’s effective combined income tax rate for 2021 was 3.89% as compared to 11.04% for 2020.

Property and Other Taxes

For 2021, property and other taxes increased $2.4 million, or 8.0%, as compared to 2020. The increase was due to an increase in our assessed property values for utility plant placed in service during the year.

Other Income and Expenses

In 2021, net other income increased $15.4 million from net other income of $2.0 million in 2020. The increase was due primarily to a $5.8 million increase in non-regulated revenue and $14.9 million decrease in other components of net periodic benefit costs. These increases were partially offset by a $2.4 million increase in non-regulated expenses, $1.8 million decrease in allowance for funds used during construction, and $0.5 million decrease in the unrealized gain from certain benefit plan investments due to market conditions. Changes in other components of net periodic benefit costs for regulated California operations generally do not affect net income attributable to California Water Service Group, as the CPUC has allowed the Company to record these costs in balancing accounts for future recovery, creating a corresponding change to revenue.

Net Interest Expense

In 2021, net interest expense increased $1.4 million as compared to 2020. The increase was due primarily to an increase in financing to support the capital investment program from the 2018 GRC.

Water Supply

California's normal weather pattern yields little precipitation between mid-spring and mid-fall. The Washington Water service areas receive precipitation in all seasons, with the heaviest amounts during the winter. New Mexico Water's rainfall is heaviest in the summer monsoon season. Hawaii Water receives precipitation throughout the year, with the largest amounts in the winter months. Water usage in all service areas is highest during the warm and dry summers and declines in the cool winter months. Rain and snow during the winter months replenish underground water aquifers and fill reservoirs, providing the water supply for subsequent delivery to customers. Management believes that supply pumped from underground aquifers and purchased from wholesale suppliers will be adequate to meet customer demand during 2022 and thereafter. However, water rationing may be required in future periods, if declared by the state or local jurisdictions. Long-term water supply plans are developed for each of our districts to help assure an adequate water supply under various operating and supply conditions. Some districts have unique challenges in meeting water quality standards, but management believes that supplies will meet current standards using current treatment processes.

Liquidity and Capital Resources

Cash flow from Operations

During 2021, we generated cash flow from operations of $231.7 million, compared to $117.9 million during 2020. The increase in 2021 was primarily due to the billing of the IRMA receivable in 2021 for which a receivable was recorded in 2020 and a decrease in the funding for pension and other post-retirement benefits in 2021.

The water business is seasonal. Billed revenue is lower in the cool, wet winter months when less water is used compared to the warm, dry summer months when water use is highest. This seasonality results in the possible need for short-term borrowings under the bank lines of credit in the event cash is not sufficient to cover operating costs during the winter period. The increase in cash flow during the summer allows for a pay down of short-term borrowings. Customer water usage can be lower than normal in years when more than normal precipitation falls in our service areas or temperatures are lower than normal, especially in the summer months. The reduction in water usage reduces cash flow from operations and increases the need for short-term bank borrowings.

Investing Activities

During 2021 and 2020 we used $293.2 million and $298.7 million, respectively, of cash for capital expenditures, both Company-funded and developer-funded. Capital expenditures in 2021 were slightly below the high end of budgeted capital expenditures of $300.0 million. Cash used in investing activities fluctuates each year largely due to the availability of construction resources and our ability to obtain construction permits in a timely manner.

We also paid $6.5 million and $40.5 million for the acquisition of Kapalua Water and BVRT Utility Holding Company, LLC in 2021 and for the acquisitions of Rainier View Water Company and Kalealoa Water Company in 2020, respectively.

Financing Activities

During 2021, we borrowed $200.0 million, and paid down $535.0 million on our unsecured revolving credit facilities to fund capital expenditures and for general corporate purposes. We also received $28.2 million of advances and contributions in aid of construction, which was reduced by refunds to developers of $10.6 million. We issued $280.0 million of First Mortgage Bonds to pay down our unsecured revolving credit facilities, to fund capital expenditures and for general corporate purposes, and we repaid $5.4 million of First Mortgage Bonds that matured in 2021 and other long-term debt obligations. In addition, we issued $197.7 million of Company common stock through our at-the-market equity plan and our employee stock purchase plan.

On March 29, 2019, the Company and Cal Water entered into certain syndicated credit agreements, which provide for unsecured revolving credit facilities of up to an initial aggregate amount of $550.0 million for a term of five years. The revolving credit facilities amend, expand, and replace the Company’s and its subsidiaries’ prior credit facilities originally entered into on May 10, 2015. The new credit facilities extended the terms until March 29, 2024, and increased Cal Water’s unsecured revolving line of credit. The Company and subsidiaries that it designates may borrow up to $150.0 million under the Company’s revolving credit facility. Cal Water may borrow up to $400.0 million under its revolving credit facility. All borrowings must be repaid within 24 months unless a different period is required or authorized by the CPUC. Additionally, the credit facilities may be increased by up to an incremental $150.0 million under the Cal Water facility and $50.0 million under the Company facility, subject in each case to certain conditions. The proceeds from the revolving credit facilities may be used for working capital purposes. Borrowings under the credit facilities typically have maturities varying between one and nine months and will bear interest annually at a rate equal to (i) the base rate or (ii) the Eurodollar rate, plus an applicable margin of 0.650% to 0.875%, depending on the Company and its subsidiaries’ consolidated total capitalization ratio.

The under-collected net WRAM and MCBA receivable balances were $72.8 million and $67.8 million as of December 31, 2021 and 2020, respectively. The increase of $5.0 million from December 31, 2020 to December 31, 2021 was primarily due lower than adopted customer usage. The under-collected net WRAM and MCBA receivable balances were primarily financed by Cal Water with short-term and long-term financing arrangements to meet operational cash requirements. Interest on the under-collected net WRAM and MCBA receivable balances, the interest recoverable from customers, is limited to the current 90-day commercial paper rate, which is significantly lower than Cal Water's short and long-term financing rates.

At the January 2022 meeting, the Board of Directors declared the quarterly dividend, increasing it for the 55th consecutive year. The quarterly dividend was raised from $0.23 to $0.25 per common share. This represents an indicated annual rate of $1.00 per common share. Dividends have been paid for 76 consecutive years. The annual dividends paid per common share in 2021, 2020, and 2019 were $0.92, $0.85, and $0.79, respectively. Earnings not paid as dividends are reinvested in the business for the benefit of stockholders. The dividend payout ratio was 46.9% in 2021, 43.1% in 2020, and 60.3% in 2019 for an average of 48.7% over the 3-year period. Our long-term targeted dividend payout ratio is 60%.

Short-Term Financing

Short-term liquidity is provided by the bank lines of credit described above and by internally generated funds. As of December 31, 2021, there were borrowings of $35.0 million outstanding on our unsecured revolving lines of credit, compared to $370.0 million outstanding on our unsecured revolving lines of credit as of December 31, 2020.

Given our ability to access our lines of credit on a daily basis, cash balances are managed to levels required for daily cash needs and excess cash is invested in short-term or cash equivalent instruments. Minimal operating levels of cash are maintained for Washington Water, New Mexico Water, Hawaii Water, and Texas Water.

The Company and certain designated subsidiaries may borrow up to $150.0 million under its credit facility. Cal Water may borrow up to $400.0 million under its credit facility; however, all borrowings currently need to be repaid within 24 months unless otherwise authorized by the CPUC.

Both credit agreements contain affirmative and negative covenants and events of default customary for credit facilities of this type including, among other things, limitations, and prohibitions relating to additional indebtedness, liens, mergers, and asset sales. In addition, these unsecured credit agreements contain financial covenants governing the Company and its subsidiaries' "consolidated total capitalization ratio" not to exceed 66.7% and "interest coverage ratio" of three or more (each as defined in the respective credit agreements). As of December 31, 2021, our consolidated total capitalization ratio was 49.5% and the interest coverage ratio was greater than five. In summary, as of such date, we met all of the covenant requirements and were eligible to use the full amounts of these credit agreements.

Long-Term Financing

Long-term financing is accomplished using both debt and equity. Cal Water was authorized to issue $700.0 million of debt and common stock to finance capital projects and operations by a CPUC decision dated November 5, 2020. In addition, the decision retained approximately $94.0 million of prior financing authority and determined that refinancing long-term debt did not count against the authorization. The CPUC requires that any loans from Cal Water to the Company be at arm’s length. This restriction did not materially affect the Company's ability to meet its cash obligations in 2021. Management does not expect this restriction to have a material impact on the Company's ability to meet its cash obligations in 2022 and beyond.

On May 11, 2021, Cal Water issued $280.0 million of First Mortgage Bonds (see Note 9) in a private placement. Cal Water used the net proceeds from the sale of the Bonds to refinance existing indebtedness and for general corporate purposes. Long-term financing, which includes First Mortgage Bonds, senior notes, other debt securities, and common stock, has typically been used to replace short-term borrowings and fund capital expenditures. Internally generated funds, after making dividend payments, provide positive cash flow, but have not been at a level to meet the needs of our capital expenditure requirements. Management expects this trend to continue given our capital expenditures plan for the next four years. Some capital expenditures are funded by payments received from developers for contributions in aid of construction or advances for construction. Funds received for contributions in aid of construction are non-refundable, whereas funds classified as advances in construction are refundable. Management believes long-term financing is available to meet our cash flow needs through issuances in both debt and equity instruments.

Additional information regarding the bank borrowings and long-term debt is presented in Notes 8 and 9 in the Notes to Consolidated Financial Statements.

Equity Issuance

Summarized Financial Information for Guarantors and the Issuer of Guaranteed Securities.

On April 17, 2009, Cal Water (Issuer) issued $100.0 million aggregate principal amount of 5.500% First Mortgage Bonds due 2040, all of which are fully and unconditionally guaranteed by the Company (Guarantor). Certain subsidiaries of the Company do not guarantee the security and are referred to as Non-guarantors. The Guarantor fully, absolutely, irrevocably and unconditionally guarantees the due and punctual payment when due, whether at stated maturity, by acceleration, by notice of prepayment or otherwise, of the principal of, premium, if any, and interest on the bonds. The bonds rank equally among Cal Water's other first mortgage bonds.

The following tables present summarized financial information of the Issuer subsidiary and the Guarantor. All intercompany balances and transactions between Issuer and Guarantor have been eliminated. The information presented below excludes eliminations necessary to arrive at the information on a consolidated basis. In presenting the summarized financial statements, the equity method of accounting has been applied to the Guarantor interests in the Issuer. The summarized information excludes financial information of the Non-issuers, including earnings from and investments in these entities.

Off-Balance Sheet Arrangements

We do not have commitments or obligations, including contingent obligations, arising from arrangements with unconsolidated entities or persons that have, or are reasonably likely to have, a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, cash requirements, or capital resources even when the arrangement results in no obligation being reported in our consolidated balance sheets.

Contractual Obligations

The contractual obligations presented in the table below represent our estimates of future payments under fixed contractual obligations and commitments. Changes in our business needs, cancellation provisions and changes in interest rates, as well as action by third parties and other factors, may cause these estimates to change. Therefore, our actual payments in future periods may vary from those presented in the table below.

The following table summarizes our contractual obligations as of December 31, 2021.

a.Long-term debt payments include annual sinking fund payments on First Mortgage Bonds, maturities of long-term debt, and annual payments on other long-term obligations, exclusive of unamortized debt issuance costs of $5.3 million.

b.Pension and postretirement benefits include $2.1 million of short-term pension obligations.

c.Finance lease obligations represent total cash payments to be made in the future and includes interest expense of $0.9 million.

d.Estimated annual contractual obligations are based on the same payment levels as 2021.

For pension and postretirement benefits other than pensions obligations, see Note 12 of the Notes to the Consolidated Financial Statements.

Table of Contents

Advances for construction represent annual contract refunds to developers for the cost of water systems paid for by the developers. The contracts are non-interest bearing, and refunds are generally on a straight-line basis over a 40-year period. System and facility leases include obligations associated with leasing water systems and rents for office space.

For finance and operating lease obligations, see Note 15 of the Notes to the Consolidated Financial Statements.

Cal Water has water supply contracts with wholesale suppliers in 13 of its operating districts and for the two leased systems in Hawthorne and Commerce. For each contract, the cost of water is established by the wholesale supplier and is generally beyond our control. The amount paid annually to the wholesale suppliers is charged to purchased water expense on our statement of income. Most contracts do not require minimum annual payments and vary with the volume of water purchased. For more details related to water supply contracts, see Note 15 of the Notes to the Consolidated Financial Statements.

Capital Requirements

Capital requirements consist primarily of new construction expenditures for expanding and replacing utility plant facilities and the acquisition of water systems. They also include refunds of advances for construction.

Company-funded and developer-funded utility plant expenditures were $293.2 million and $298.7 million in 2021 and 2020, respectively. A majority of capital expenditures was associated with mains and water treatment equipment.

For 2022, the Company's capital program will be dependent in part on the timing and nature of regulatory approvals in connection with Cal Water's 2021 GRC filing. The Company proposed to the CPUC spending $1.0 billion on water infrastructure investments in 2022-2024. Capital expenditures in California are evaluated in the context of the pending GRC and may change as the case moves forward. We expect our annual capital expenditure to increase during the next five years due to increasing needs to replace and maintain infrastructure.

Management expects developer-funded expenditures in 2022. These expenditures will be financed by developers through refundable advances for construction and non-refundable contributions in aid of construction. Developers are required to deposit the cost of a water construction project with us prior to our commencing construction work, or the developers may construct the facilities themselves and deed the completed facilities to us. Funds are generally received in advance of incurring costs for these projects. Advances are normally refunded over a 40-year period without interest. Future payments for advances received are listed under contractual obligations above. Because non-Company-funded construction activity is solely at the discretion of developers, we cannot predict the level of future activity. The cash flow impact is expected to be minor due to the structure of the arrangements.

Capital Structure

Total equity was $1,183.0 million at December 31, 2021, compared to $921.3 million at December 31, 2020. The Company sold 3,286,865 and 1,710,779 shares of its common stock in 2021 and 2020, respectively through its at-the-market equity program.

Total capitalization, including the current portion of long-term debt, was $2,244.0 million at December 31, 2021 and $1,707.6 million at December 31, 2020. Cal Water repaid $5.4 million of other long-term debt obligations in 2021 and $22.1 million for matured First Mortgage Bonds and other long-term debt obligations in 2020. In future periods, the Company intends to issue common stock and long-term debt to finance our operations. The capitalization ratios will vary depending upon the method we choose to finance our operations.

At December 31, capitalization ratios were:


	2021		2020
Equity	52.7	%	54.0	%
Long-term debt	47.3	%	46.0	%

The return (from both regulated and non-regulated operations) on average equity was 9.6% in 2021 compared to 11.4% in 2020. Cal Water does not include construction work in progress in its regulated rate base; instead, Cal Water was authorized to record AFUDC on construction work in progress, effective January 1, 2017. Construction work in progress for Cal Water was $200.7 million at December 31, 2021 and $156.6 million at December 31, 2020.

Acquisitions

Refer to "Note 16 - Acquisitions" for 2021 and 2020 acquisition activity.

Real Estate Program

We own real estate. From time to time, certain parcels are deemed no longer used or useful for water utility operations. Most surplus properties have a low cost basis. We developed a program to realize the value of certain surplus properties through sale or lease of those properties. The program will be ongoing for a period of several years. There were no significant sales in 2021 and 2020. As sales are dependent on real estate market conditions, future sales, if any, may or may not be at prior year levels.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk.

We do not participate in hedge arrangements, such as forward contracts, swap agreements, options, or other contractual agreements to mitigate the impact of market fluctuations on our assets, liabilities, production, or contractual commitments. We operate only in the United States and, therefore, are not subject to foreign currency exchange rate risks.

Interest Rate Risk

We are subject to interest rate risk, although this risk is lessened because we operate in a regulated industry. If interest rates were to increase, management believes customer rates would increase accordingly, subject to Commission approval in future GRC filings. The majority of our debt is long-term at a fixed rate. Interest rate risk does exist on short-term borrowings within our credit facilities, as these interest rates are variable. We also have interest rate risk on new financing, as higher interest cost may occur on new debt if interest rates increase.

Over the next 12 months, approximately $5.2 million of the $1,061.0 million of existing long-term debt instruments will mature or require sinking fund payments. Applying a hypothetical 10 percent increase in the rate of interest charged on those borrowings would not have a material effect on our earnings.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of California Water Service Group and subsidiaries (the "Company") as of December 31, 2021 and 2020, the related consolidated statements of income, common stockholders' equity, and cash flows, for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the "financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

Basis for Opinions

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on these financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

Table of Contents

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Impact of Rate Regulation on the Financial Statements — Refer to Note 2 to the financial statements

Critical Audit Matter Description

The Company is subject to rate regulation by the California Public Utilities Commission (“the Commission”), which has jurisdiction with respect to the rates of water and wastewater service companies in California. Management has determined it meets the requirements under accounting principles generally accepted in the United States of America to prepare its financial statements applying the specialized rules to account for the effects of cost-based rate regulation. Accounting for the economics of rate regulation impacts multiple financial statement line items and disclosures, such as utility plant; regulatory assets and liabilities; operating revenue; operating expenses; and depreciation expense.

The Commission establishes rates that are designed to permit the recovery of the cost of service and a return on investment. The Company’s rates are subject to regulatory rate-setting processes including a General Rate Case proceeding. The Company capitalizes and records regulatory assets for costs that would otherwise be charged to expense if it is probable that the incurred costs will be recovered in future rates. If costs expected to be incurred in the future are currently being recovered through rates, the Company records those expected future costs as regulatory liabilities. Determining probability requires significant judgment by management and includes, but is not limited to, consideration of testimony presented in regulatory hearings, proposed regulatory decisions, final regulatory orders, and the strength or status of applications for rehearing or state court appeals. If the Company determines that a portion of the assets used in utility operations are not recoverable in customer rates, the Company would be required to recognize the loss of the assets disallowed.

Table of Contents

We identified the impact of rate regulation as a critical audit matter due to the significant judgments that underlie the Company’s regulatory account balances and disclosures and the high degree of subjectivity involved in assessing the impact of regulatory decisions on the financial statements. Management judgments include interpreting the intent of the Commission’s decisions when appropriately measuring related regulatory assets or liabilities and assessing the probability of (1) recovery in future rates of incurred costs and (2) the requirement to refund to customers amounts collected prior to costs being incurred. Given that management’s accounting judgements are based on assumptions about the outcome of future regulatory decisions and interpretation of new or revised regulatory decisions, auditing these judgments required specialized knowledge of accounting for rate regulation and the rate setting process due its inherent complexities and pervasive impact on the financial statements.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the interpretation of new or revised regulatory decisions, and the uncertainty of future regulatory hearings, proposed regulatory decisions, final regulatory orders, and the strength or status of applications for rehearing or state court appeals included the following, among others:

•We tested the effectiveness of management’s controls over the determination of regulatory assets or liabilities and the evaluation of the likelihood of (1) the recovery in future rates of costs incurred as property, plant, and equipment and deferred as regulatory assets, and (2) a refund or a future reduction in rates that should be reported as regulatory liabilities. We also tested the effectiveness of management’s controls over the initial recognition of amounts as utility plant; regulatory assets or liabilities; and the monitoring and evaluation of regulatory developments that may affect the likelihood of recovering costs in future rates or of a future reduction in rates.

•We read regulatory orders issued by the Commission for the Company, regulatory statutes, interpretations, procedural memorandums, filings made by interveners, and other publicly available information to evaluate management’s interpretation of the accounting impacts of any new or revised regulatory decisions and their impact on measuring related regulatory assets and liabilities. We evaluated the external information and compared it to management’s recorded regulatory asset and liability balances for completeness.

•We obtained supporting documentation (such as letters or memorandums) from management, as appropriate, regarding probability of recovery for regulatory assets or refund or future reduction in rates for regulatory liabilities not yet addressed in a regulatory order to assess management’s assertion that amounts are probable of recovery or a future reduction in rates.

•We obtained supporting documentation from management regarding their interpretation of the intent of Commission decisions and evaluated management’s assumptions and methodologies used in measuring regulatory assets and liabilities for compliance with the related orders. We reconciled the underlying data or inputs used in the measurement to rate decisions approved by the Commission and tested the mathematical accuracy of the calculations.

•We evaluated the Company’s disclosures related to the impacts of rate regulation, including the balances recorded and regulatory developments.

1 ORGANIZATION AND OPERATIONS

California Water Service Group (Company) is a holding company that provides water utility and other related services in California, Washington, New Mexico, Hawaii and Texas through its wholly-owned and non-wholly owned subsidiaries. California Water Service Company (Cal Water), Washington Water Service Company (Washington Water), New Mexico Water Service Company (New Mexico Water), and Hawaii Water Service Company, Inc. (Hawaii Water) provide regulated utility services under the rules and regulations of their respective state's regulatory commissions (jointly referred to as the Commissions). CWS Utility Services and HWS Utility Services LLC provide non-regulated water utility and utility-related services. TWSC, Inc. (Texas Water) holds regulated and contracted wastewater utilities.

The Company operates in one reportable segment, providing water and related utility services.

Basis of Presentation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and include the Company's accounts and those of its wholly and non-wholly owned subsidiaries. The non-wholly owned subsidiary was consolidated using the voting interest model as the Company owns a majority of the voting interests in the non-wholly owned subsidiary. All intercompany transactions and balances have been eliminated from the consolidated financial statements. In the opinion of management, the consolidated financial statements reflect all adjustments that are necessary to provide a fair presentation of the results for the periods covered.

The preparation of the Company's consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the consolidated balance sheet dates and the reported amounts of revenues and expenses for the periods presented. These include, but are not limited to, estimates and assumptions used in determining the Company's regulatory asset and liability balances based upon probability assessments of regulatory recovery, utility plant useful lives, revenues earned but not yet billed, asset retirement obligations, allowance for credit losses, pension and other employee benefit plan liabilities, and income tax-related assets and liabilities. Actual results could differ from these estimates.

Noncontrolling Interests

Noncontrolling interests in the Company’s consolidated financial statements represents the 24.8% interest not owned by Texas Water in a consolidated subsidiary. Texas Water obtained control over the subsidiary on May 1, 2021. Since the Company controls this subsidiary, its financial statements are consolidated with those of the Company, and the noncontrolling owner’s 24.8% share of the subsidiary’s net assets and results of operations is deducted and reported as noncontrolling interests on the consolidated balance sheet and as net loss attributable to noncontrolling interests in the consolidated statement of operations. The Company reports noncontrolling interests in consolidated entities as a component of equity separate from the Company’s equity. The Company’s net income attributable to California Water Service Group excludes a net loss attributable to the noncontrolling interests.

2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Operating Revenue

The following table disaggregates the Company’s operating revenue by source for the years ended December 31, 2021, 2020 and 2019:


	2021		2020		2019
Revenue from contracts with customers	$	765,704	$	697,577	$	664,358
Regulatory balancing account revenue	25,205		96,730		50,199
Total operating revenue	$	790,909	$	794,307	$	714,557

Revenue from contracts with customers

The measurement of sales to customers is generally based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each month, the Company estimates consumption since the date of the last meter reading and a corresponding unbilled revenue is recognized. The estimate is based upon the number of unbilled days that month and the average daily customer billing rate from the previous month (which fluctuates based upon customer usage).

In the following table, revenue from contracts with customers is disaggregated by class of customers for the years ended December 31, 2021, 2020 and 2019:

2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Regulatory balancing account revenue

The Company’s ability to recover revenue requirements authorized by the California Public Utilities Commission (CPUC) in its triennial general rate case (GRC) is decoupled from the volume of the sales. Regulatory balancing account revenue is revenue related to rate mechanisms authorized in California by the CPUC, which allow the Company to recover the authorized revenue and are not considered contracts with customers. These mechanisms include the following:

Cost-recovery rates, such as the Modified Cost Balancing Account (MCBA), Conservation Expense Balancing Account (CEBA), Pension Cost Balancing Account (PCBA), and Health Cost Balancing Account (HCBA), generally provide for recovery of the adopted levels of expenses for purchased water, purchased power, pump taxes, water conservation program costs, pension, and health care. Variances between adopted and actual costs are recorded as regulatory balancing account revenue.

The CPUC issued a decision effective August 27, 2020 requiring that Class A companies submitting GRC filings after the effective date to be (i) precluded from proposing the use of a full decoupling WRAM and (ii) allowed the use of Monterey-Style Water Revenue Adjustment Mechanisms (MWRAM) and Incremental Cost Balancing Accounts (ICBA). The MWRAM tracks the difference between the revenue received for actual metered sales through the tiered volumetric rate and the revenue that would have been received with the same actual metered sales if a uniform rate would have been in effect. The ICBA tracks differences in the authorized prices of water production costs and actual prices of water production costs. Cal Water has complied with this decision in its recent 2021 GRC filing.

Non-Regulated Revenue

The following tables disaggregate the Company’s non-regulated revenue by source for the years ended December 31, 2021, 2020, and 2019:


	2021		2020		2019
Operating and maintenance revenue	$	16,276	$	11,481	$	12,655
Other non-regulated revenue	3,741		3,043		4,271
Non-regulated revenue from contracts with customers	20,017		14,524		16,926
Lease revenue	2,744		2,398		2,279
Total non-regulated revenue	$	22,761	$	16,922	$	19,205

Operating and maintenance services are provided for non-regulated water and wastewater systems owned by private companies and municipalities. The Company negotiates formal agreements with the customers under which they provide operating, maintenance and customer billing services related to the customers’ water system. The formal agreements outline the fee schedule for the services provided. The agreements typically call for a fee-per-service or a flat-rate amount per month. The Company satisfies its performance obligation of providing operating and maintenance services over time as services are rendered; as a result, the Company employs the invoice practical expedient and recognizes revenue in the amount that it has the

right to invoice. Contract terms are generally short-term and, as a result, no separate financing component is recognized for its collections from customers, which generally require payment within 30 days of billing.

Other non-regulated revenue primarily relates to services for the design and installation of water mains and other water infrastructure for customers outside the regulated service areas and insurance program administration.

Lease revenue is not considered revenue from contracts with customers and is recognized following operating lease standards. The Company is the lessor in operating lease agreements with telecommunications companies under which cellular phone antennas are placed on the Company's property. The Company provides the lessee the right to ingress and egress across lessor property to access the antennas. The minimum rents are recognized on a straight-line basis over the terms of the leases, which may span multiple years. The excess rents are recognized over amounts contractually due pursuant to the underlying leases and is included in a deferred receivable account in the accompanying balance sheet. The leases generally have terms of 5 to 10 years, with lessee options to extend the lease for up to 15 years. The exercise of lease renewal options is at the lessee’s sole discretion. Most of the Company’s lease agreements contain mutual termination options that require prior written notice by either lessee or lessor. A subset of the Company’s leases contains variable lease payments that depend on changes in the consumer price index (CPI).

The Company determines if an arrangement is a lease at inception. Generally, a lease agreement exists if the Company determines that the arrangement gives the lessee control over the use of an identified asset and obtains substantially all of the benefits from the identified asset.

Maturities of lease payments to be received are as follows:


Year Ending December 31,	Operating Leases
2022	$	2,274
2023	1,807
2024	1,532
2025	1,080
2026	631
Thereafter	88

Allowance for Credit Losses

The Company measures expected credit losses for Customer Receivables, Other Receivables, and Unbilled Revenue on an aggregated level. These receivables are generally trade receivables due in one year or less or expected to be billed and collected in one year or less. The expected credit losses for Other Receivables and Unbilled Revenue are inconsequential. Customer receivables include receivables for water and wastewater services provided to residential customers, business, industrial, public authorities, and other customers. The expected credit losses for business, industrial, public authorities, and other customers are inconsequential. The overall risks related to the Company’s receivables are low as water and wastewater services are seen as essential services. The estimate for the allowance for credit losses is based on a historical loss ratio, in conjunction with a qualitative assessment of elements that impact the collectability of receivables to determine if the allowance for credit losses should be further adjusted in accordance with the accounting guidance for credit losses. Management contemplates available current information such as changes in economic factors, regulatory matters, industry trends, payment options and programs available to customers, and the methods that the Company is able to utilize to ensure payment.

In 2021, the Company reviewed its allowance for credit losses utilizing a quantitative assessment, which included trend analysis of customer billing and collection, aging by customer class, and unemployment rates since the outbreak of COVID-19 in the first quarter of 2020. The Company also utilized a qualitative assessment, which considered the future collectability on customer outstanding balances, management's estimate of the cash recovery, and a general assessment of the economic conditions of the locations the Company serves due to the outbreak of COVID-19. The Company is complying with the CPUC requirements to suspend customer disconnections for non-payment and ceased agency collection activities, and anticipates this situation will continue until further notice. The Company has also contemplated funds that the Company expected to receive from the California Water and Water Arrearages Payment Program (Program) (see note 17 for more details). The Program was created by the California Legislature, is administered by the State Water Resources Control Board and will provide relief to

community water and wastewater systems for unpaid bills – arrearages – related to the COVID-19 pandemic. Based on the above assessments, the Company adjusted its allowance for credit losses accordingly.

The following table presents the activity in the allowance for credit losses for the periods ended December 31, 2021, 2020, and 2019.

Other Receivables

As of December 31, 2021 and 2020, other receivables were:


	2021		2020
Accounts receivables from developers	$	6,909	$	9,077
Income tax receivables	5,579		5,561
Other	5,964		5,693
Total other receivables	$	18,452	$	20,331

Utility Plant

Utility plant is carried at original cost when first constructed or purchased, or at fair value when acquired through acquisition. When depreciable plant is retired, the cost is eliminated from utility plant accounts and such costs are charged against accumulated depreciation. Maintenance of utility plant is charged to operating expenses as incurred. Maintenance projects are not accrued for in advance.

Intangible assets acquired as part of water systems purchased are recorded at fair value. All other intangibles have been recorded at cost and are amortized over their useful life.

The following table represents depreciable plant and equipment as of December 31:


	2021		2020
Equipment	$	833,313	$	785,578
Office buildings and other structures	319,528		305,791
Transmission and distribution plant	2,746,788		2,554,401
Total	$	3,899,629	$	3,645,770

Depreciation of utility plant is computed on a straight-line basis over the assets' estimated useful lives including cost of removal of certain assets as follows:


			Useful Lives
Equipment			5 to 50 years
Transmission and distribution plant			40 to 65 years
Office Buildings and other structures			50 years

The provision for depreciation expressed as a percentage of the aggregate depreciable asset balances was 2.96% in 2021, 2.94% in 2020, and 2.96% in 2019.

2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Allowance for funds used during construction (AFUDC)

The AFUDC represents the capitalized cost of funds used to finance the construction of the utility plant. In general, AFUDC is applied to Cal Water construction projects requiring more than one month to complete. No AFUDC is applied to projects funded by customer advances for construction, contributions in aid of construction, or applicable state-revolving fund loans. AFUDC includes the net cost of borrowed funds and a rate of return on other funds when used, and is recovered through water rates as the utility plant is depreciated.

The amount of AFUDC related to equity funds and to borrowed funds for 2021, 2020, and 2019 are shown in the table below:


	2021		2020		2019
Allowance for equity funds used during construction	$	3,186	$	4,976	$	6,685
Allowance for borrowed funds used during construction	1,766		3,185		3,670
Total	$	4,952	$	8,161	$	10,355

Asset Retirement Obligation

The Company has a legal obligation to retire wells in accordance with State Water Resources Control Board regulations. In addition, upon decommission of a wastewater plant or lift station certain wastewater infrastructure would need to be retired in accordance with State Water Resources Control Board regulations. An asset retirement cost and corresponding retirement obligation is recorded when a well or waste water infrastructure is placed into service. As of December 31, 2021 and 2020, the retirement obligation is estimated to be $29.5 million and $27.8 million, respectively. The retirement obligation is recorded as part of "Other long-term liabilities" within the Consolidated Balance Sheet. The change only impacted the consolidated balance sheets as the Company recognizes a regulatory asset or liability for the timing differences between the recognition of expenses and costs recovered through the ratemaking process.

The following is a reconciliation of the beginning and ending aggregate carrying amount of asset retirement obligations, which are included in “Other long-term liabilities” on the consolidated balance sheets as of December 31, 2021 and 2020:


	2021		2020
Obligation at beginning of the year	$	27,849	$	25,646
Additional liabilities incurred	119		640
Liabilities settled	(201)		(12)
Accretion	1,692		1,575
Obligation at the end of the year	$	29,459	$	27,849

Cash, Cash Equivalents, and Restricted Cash

Cash and cash equivalents include highly liquid investments with remaining maturities of three months or less at the time of acquisition. In 2021 and 2020, restricted cash includes $0.5 million and $0.6 million, respectively, of proceeds collected through a surcharge on certain customers' bills plus interest earned on the proceeds and is used to service California Safe Drinking Water Bond obligations.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash within the Consolidated Balance Sheets that total to the amounts shown on the Consolidated Statements of Cash Flows as of December 31:

2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Regulatory Assets and Liabilities

Because the Company operates almost exclusively in a regulated business, the Company is subject to the accounting standards for regulated utilities. The Commissions in the states in which the Company operates establish rates that are designed to permit the recovery of the cost of service and a return on investment. The Company capitalizes and records regulatory assets for costs that would otherwise be charged to expense if it is probable that the incurred costs will be recovered in future rates. Regulatory assets are amortized over the future periods that the costs are expected to be recovered. If costs expected to be incurred in the future are currently being recovered through rates, the Company records those expected future costs as regulatory liabilities. In general, the Company does not earn a return on regulatory assets if the related costs do not accrue interest. Accordingly, the Company earns a return only on its regulatory assets for net WRAM and MCBA, PCBA, HCBA, and IRMA receivables. In addition, the Company records regulatory liabilities when the Commissions require a refund to be made to the Company's customers over future periods.

If the Company determines that a portion of the Company's assets used in utility operations is not recoverable in customer rates, the Company would be required to recognize the loss of the assets disallowed.

See Note 4 - Regulatory Assets and Liabilities for details of the Company's regulatory assets and liabilities.

Impairment of Long-Lived Assets, Intangibles and Goodwill

The Company's long-lived assets include transmission and distribution plant, equipment, land, buildings, and intangible assets. Long-lived assets, other than land, are depreciated or amortized over their estimated useful lives, and are reviewed for impairment whenever changes in circumstances indicate the carrying value of the assets may not be recoverable. Such circumstances would include items such as a significant decrease in the market value of a long-lived asset, a significant adverse change in the manner in which the asset is being used or planned to be used or in its physical condition, or a history of operating or cash flow losses associated with the uses of the asset. In addition, changes in the expected useful life of these long-lived assets may also be an impairment indicator. When such events or changes occur, the Company estimates the fair value of the asset from future cash flows expected to result from the use and, if applicable, the eventual disposition of the assets, and compare that to the carrying value of the asset. If the carrying value is greater than the fair value, then an impairment loss is recognized equal to the amount by which the asset's carrying value exceeds its fair value. The key variables that must be estimated include assumptions regarding sales volume, rates, operating costs, labor and other benefit costs, capital additions, assumed discount rates and other economic factors. These variables require significant management judgment and include inherent uncertainties since they are forecasting future events. A variation in the assumptions used could lead to a different conclusion regarding the realizability of an asset and, thus could have a significant effect on the consolidated financial statements.

Goodwill is measured as the excess of the cost of an acquisition over the sum of the amounts assigned to identifiable assets acquired less liabilities assumed. Goodwill is not amortized but instead is reviewed annually in the fourth quarter for impairment or more frequently if impairment indicators arise. The impairment test is performed at the reporting unit level using fair-value based approach in which the fair value of the reporting unit is compared to the reporting unit's carrying value. If the fair value of the reporting unit is less than its carrying amount, then an impairment loss is recognized equal to the difference.

Long-Term Debt Premium, Discount and Expense

The premiums, discounts, and issuance expenses on long-term debt are amortized over the original lives of the related debt on a straight-line basis which approximates the effective interest method. Premiums paid on the early redemption of certain debt and the unamortized original issuance discount and expense are amortized over the life of new debt issued in conjunction with the early redemption. Amortization expense included in interest expense for 2021, 2020, and 2019 was $0.4 million, $0.4 million, and $0.7 million, respectively.

Advances for Construction

Advances for construction consist of payments received from developers for installation of water production and distribution facilities to serve new developments. Advances are excluded from rate base for rate setting purposes. Annual refunds are made to developers without interest. Advances of $198.1 million and $195.6 million, at December 31, 2021 and 2020 respectively, will be refunded primarily over a 40-year period in equal annual amounts.

Estimated refunds of advances are shown in the table below.

Contributions in Aid of Construction

Contributions in aid of construction represent payments received from developers, primarily for fire protection purposes, which are not subject to refunds. Facilities funded by contributions are included in utility plant, but excluded from rate base. Depreciation related to assets acquired from contributions is charged to the Contributions in Aid of Construction account.

Income Taxes

The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Measurement of the deferred tax assets and liabilities is at enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. The Company evaluates the need for a valuation allowance on deferred tax assets based on historical taxable income and projected taxable income for future tax years.

Historically the Commissions reduced revenue requirements for the tax effects of certain originating temporary differences and allowed recovery of these tax costs as the related temporary differences reverse. The Commissions have granted the Company rate increases to reflect the normalization of the tax benefits of the federal accelerated methods and available Investment Tax Credits (ITC) for all assets placed in service after 1980. ITCs are deferred and amortized over the lives of the related properties for book purposes. The CPUC sets rates utilizing the flow through method of accounting for state income taxes.

With the enactment of the TCJA, Contributions in Aid of Construction (CIAC) received from developers after December 22, 2017 became fully taxable for federal income tax purposes. On November 15, 2021, the Infrastructure Investment and Jobs Act was signed into law, which reverses the TCJA treatment of CIAC. Effective January 1, 2021, only the service portion of CIAC is taxable for federal income tax purpose.

The accounting standards for accounting for uncertainty in income taxes allows the inclusion of interest and penalties related to uncertain tax positions as a component of income taxes (see Note 11 - Income Taxes).

Workers' Compensation

For workers' compensation, the Company estimates the liability associated with claims submitted and claims not yet submitted based on historical data. Expenses for workers compensation insurance are included in rates on a pay-as-you-go basis. Therefore, a corresponding regulatory asset has been recorded.

2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Earnings per Share

The computations of basic and diluted earnings per share are noted below. Basic earnings per share are computed by dividing net income attributable to California Water Service Group by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts were exercised or converted into common stock. Restricted Stock Awards (RSAs) are included in the common shares outstanding because the shares have all the same voting and dividend rights as issued and unrestricted common stock. Restricted Stock Unit Awards (RSUs) are not included in diluted shares for financial reporting until authorized by the Organization & Compensation Committee of the Board of Directors.

Stock-based Compensation

Stock-based compensation cost is measured at the grant date based on the fair value of the award. The Company recognizes compensation expense on a straight-line basis over the requisite service period, which is the vesting period.

Comprehensive Income or Loss

Comprehensive income for all periods presented was the same as net income attributable to California Water Service Group.

Accumulated Other Comprehensive Income

The Company did not have any accumulated other comprehensive income or loss transactions as of December 31, 2021 and 2020.

Adoption of New Accounting Standards in 2021

In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions for performing intraperiod tax allocations, recognizing deferred taxes for investments, and calculating income taxes in interim periods. The guidance also simplifies the accounting for franchise taxes, transactions that result in a step-up in the tax basis of goodwill, and the effect of enacted changes in tax laws or rates in interim periods. The Company adopted ASU 2019-12 in the first quarter of 2021 and the adoption did not have a material impact to the Company’s Consolidated Financial Statements.

Accounting Standards Issued But Not Yet Adopted

In October of 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. In a business combination, an acquirer generally recognizes assets acquired and liabilities assumed, including contract assets and contract liabilities, at their respective fair value on the acquisition date. ASU 2021-08 requires that in a business combination, an acquirer should recognize and measure contract assets acquired and contract liabilities assumed in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. The guidance provides certain practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts with customers in a business combination. The guidance is effective for

annual reporting periods beginning after December 15, 2022, including interim periods within those fiscal years. ASU 2021-08 should be applied prospectively for acquisitions occurring on or after the effective date of the amendments, and early adoption is permitted. The Company is evaluating the requirements of the guidance to determine the impact on the Company's financial statements and footnote disclosures upon adoption.

The Company's pension and retiree group health regulatory asset represents the unfunded obligation of the Company’s pension and postretirement benefit plans which the Company expects to recover from customers in the future for these plans. The retiree group health regulatory liability represents the over funded obligation of the Company’s postretirement benefit plans which the Company expects to refund to customers in the future. These plans are discussed in further detail in Note 12.

The PCBA regulatory asset and the HCBA regulatory liability represent incurred pension and healthcare costs that exceeded/was below the cost recovery in rates and is recoverable/refundable from/to customers. The other components of net periodic benefit cost regulatory asset are authorized by the Commissions and are probable for rate recovery through the capital program.

The property-related temporary differences are primarily due to: (i) the difference between book and federal income tax depreciation on utility plant that was placed in service before the regulatory Commissions adopted normalization for rate making purposes; and (ii) certain (state) deferred taxes for which flow through accounting continues to be applied to originating deferred taxes. The regulatory asset will be recovered in rates in future periods as the tax effects of the temporary differences previously flowed-through to customers reverse.

4 REGULATORY ASSETS AND LIABILITIES (Continued)

Other accrued benefits are accrued benefits for vacation, self-insured workers' compensation, and directors' retirement benefits. The net WRAM and MCBA long-term accounts receivable is the under-collected portion of recorded revenues that are not expected to be collected from customers within 12 months. The IRMA long-term accounts receivables is the additional amount the Company would have billed customers in 2020 and 2021 had the 2018 GRC been approved on time.

The asset retirement obligation regulatory asset represents the difference between costs associated with asset retirement obligations and amounts collected in rates. Tank coating represents the maintenance costs for tank coating projects that are recoverable from customers.

The CAP (formerly known as Low-income Rate Assistance) and RSF are two programs offered by Cal Water that assist qualifying customers with their monthly water bill. The programs are funded by the customers who do not qualify for the assistance. The CAP and RSF regulatory assets represent the amounts due from customers to fund the CAP and RSF credits that were provided to assist qualifying customers.

The future tax benefits due to customers primarily resulted from federal tax law changes enacted by the federal Tax Cuts and Jobs Act (TCJA) on December 22, 2017. The TCJA reduced the federal corporate income tax rate from 35 percent to 21 percent beginning on January 1, 2018, and GAAP requires the Company to re-measure all existing deferred income tax assets and liabilities to reflect the reduction in the federal tax rate on the enactment date.

The conservation program regulatory liability is for incurred conservation costs that were below the cost recovery in rates and is refundable to customers.

Short-term regulatory assets and liabilities are excluded from the above table. The short-term regulatory assets as of December 31, 2021 and 2020 were $78.6 million and $96.2 million, respectively. The short-term regulatory assets, as of December 31, 2021, and 2020 primarily consisted of net WRAM and MCBA, IRMA, and PCBA receivables.

On October 31, 2019, the Company entered into an equity distribution agreement to sell shares of its common stock having an aggregate gross sales price of up to $300.0 million from time to time depending on market conditions through an at-the-market equity program. The equity distribution agreement concluded in the fourth quarter of 2021. The Company used the net proceeds from these sales, after deducting commissions on such sales and offering expenses, for general corporate purposes, which may include working capital, construction and acquisition expenditures, investments and repurchases, and redemptions of securities. In 2021, the Company sold 3,286,865 shares of common stock through the at-the-market equity program and raised proceeds of $195.9 million net of $2.0 million in commissions paid under the equity distribution agreement.

Dividend Reinvestment and Stock Repurchase Plan

The Company has a Dividend Reinvestment and Stock Purchase Plan (DRIP Plan). Under the DRIP Plan, stockholders may reinvest dividends to purchase additional Company common stock without commission fees. The DRIP Plan also allows existing stockholders and other interested investors to purchase Company common stock through the transfer agent up to certain limits. The Company's transfer agent operates the DRIP Plan and purchases shares on the open market to provide shares for the DRIP Plan.

8 SHORT-TERM BORROWINGS

On March 29, 2019, the Company and Cal Water entered into certain syndicated credit agreements, which provide for unsecured revolving credit facilities of up to an initial aggregate amount of $550.0 million for a term of five years. The revolving credit facilities amend, expand, and replace the Company’s and its subsidiaries’ prior credit facilities originally entered into on May 10, 2015. The new credit facilities extended the terms until March 29, 2024, and increased Cal Water’s unsecured revolving line of credit. The Company and subsidiaries that it designates may borrow up to $150.0 million under the Company’s revolving credit facility. Cal Water may borrow up to $400.0 million under its revolving credit facility. All borrowings must be repaid within 24 months unless a different period is required or authorized by the CPUC. Additionally, the credit facilities may be increased by up to an incremental $150.0 million under the Cal Water facility and $50.0 million under the Company facility, subject in each case to certain conditions. The proceeds from the revolving credit facilities may be used for working capital purposes. Borrowings under the credit facilities typically have maturities varying between one month and six months and will bear interest annually at a rate equal to (i) the base rate or (ii) the Eurodollar rate, plus an applicable margin of 0.650% to 0.875%, depending on the Company and its subsidiaries’ consolidated total capitalization ratio.

The revolving credit facilities contain affirmative and negative covenants and events of default customary for credit facilities of this type including, among other things, limitations and prohibitions relating to additional indebtedness, liens, mergers, and asset sales. Also, these unsecured credit agreements contain financial covenants governing the Company and its subsidiaries' consolidated total capitalization ratio and interest coverage ratio.

As of December 31, 2021 and 2020, the outstanding borrowings on the Company lines of credit were $35.0 million and $100.0 million, respectively. There were no outstanding borrowings on the Cal Water lines of credit as of December 31, 2021 and $270.0 million in borrowings as of December 31, 2020.

On May 11, 2021, Cal Water completed the sale and issuance of $280.0 million in aggregate principal amount of First Mortgage Bonds (the Bonds) in a private placement. The Bonds consist of $130.0 million of 2.87% bonds, series ZZZ, maturing May 11, 2051, and $150.0 million of 3.02% bonds, series 1, maturing May 11, 2061.

11 INCOME TAXES (Continued)

During 2021, the Company analyzed its deferred tax balances, tax regulatory asset and tax regulatory liability based on 2018 GRC approved rates. As of December 31, 2021, the TCJA refund liability was $91.5 million. The Company continued working with other state regulators to finalize the refund to ensure compliance with federal normalization rules.

The deferred tax assets and deferred tax liabilities as of December 31, 2021 and 2020, are presented in the following table:


	2021		2020
Deferred tax assets:
Developer deposits for contributions in aid of construction	$	31,777	$	29,491
Net operating loss carryforward and tax credits	24,908		37,326
Pension liability	13,570		12,031
Income tax regulatory liability	26,565		41,151
Operating leases liabilities	4,310		4,372
Other	2,439		2,812
Total deferred tax assets	103,569		127,183
Deferred tax liabilities:
Property related basis and depreciation differences	362,139		350,923
WRAM/MCBA and interim rates balancing accounts	22,124		39,107
Operating lease-right to use asset	4,286		4,362
Other	13,965		8,823
Total deferred tax liabilities	402,514		403,215
Net deferred tax liabilities	$	298,945	$	276,032

A valuation allowance was not required at December 31, 2021 and 2020. Based on historical taxable income and future taxable income projections over the period in which the deferred assets are deductible, management believes it is more likely than not that the Company will realize the benefits of the deductible differences.

The following table reconciles the changes in unrecognized tax benefits for the periods ended December 31 2021, 2020, and 2019:


	2021		2020		2019
Balance at beginning of year	$	13,960	$	11,008	$	9,716
Additions for tax positions taken during current year	1,890		2,952		1,292
Balance at end of year	$	15,850	$	13,960	$	11,008

The Company does not expect a material change in its unrecognized tax benefits within the next 12 months. The component of unrecognized tax benefits that, if recognized, would affect the effective tax rate as of December 31, 2021, was $4.1 million, with the remaining balance representing the potential deferral of taxes to later years.

The Company's federal income tax years subject to an examination are from 2012 to 2021 and the state income tax years subject to an examination are from 2012 to 2021.

12 EMPLOYEE BENEFIT PLANS

Savings Plan

The Company sponsors a 401(k) qualified defined contribution savings plan that allows participants to contribute up to 20% of pre-tax compensation. Effective January 1, 2010, the Company matches 75 cents for each dollar contributed by the employee up to a maximum Company match of 6.0% of base salary. Company contributions were $7.4 million, $6.5 million, and $6.5 million for the years 2021, 2020 and 2019, respectively.

Pension Plans

The Company provides a qualified, defined-benefit, non-contributory pension plan for substantially all employees. The accumulated benefit obligations of the pension plan are $650.2 million and $622.0 million as of December 31, 2021 and 2020, respectively. The fair value of pension plan assets was $810.5 million and $716.8 million as of December 31, 2021 and 2020, respectively.

Prior to 2010, pension payment obligations were generally funded by the purchase of an annuity from a life insurance company. Beginning in 2010, the pension plan trust pays monthly benefits to retirees, rather than the purchase of an annuity.

The Company also maintains an unfunded, non-qualified, supplemental executive retirement plan (SERP). The unfunded SERP accumulated benefit obligations were $80.5 million and $78.0 million as of December 31, 2021 and 2020, respectively. Benefit payments under the supplemental executive retirement plan are paid currently. As a non-qualified plan, the SERP has no plan assets, however, the Company has a Rabbi trust designated to provide funding for SERP obligations. The Rabbi trust holds investments in marketable securities and corporate-owned life insurance. The recorded value of these investments was approximately $63.9 million and $57.3 million at December 31, 2021 and 2020, respectively, and is part of "Other" noncurrent assets on the Consolidated Balance Sheets.

Expected payments to be made for the pension and SERP plans are shown in the table below:


Year Ending December 31,	Pension		SERP		Total
2022	$	16,493	$	2,104	$	18,597
2023	18,215		2,301		20,516
2024	19,934		2,524		22,458
2025	21,714		2,756		24,470
2026	23,565		3,030		26,595
2027-2031	145,503		19,316		164,819
Total payments	$	245,424	$	32,031	$	277,455

The expected benefit payments are based upon the same assumptions used to measure the Company's benefit obligation at December 31, 2021, and include estimated future employee service.

The costs of the pension and retirement plans are charged to expense and utility plant. The Company makes annual contributions to fund the amounts accrued for pension cost.

Other Postretirement Plan

The Company provides substantially all active, permanent employees with medical, dental, and vision benefits through a self-insured plan. Employees retiring at or after age 58, along with their spouses and dependents, continue participation in the plan by payment of a premium. Plan assets are invested in mutual funds, short-term money market instruments and commercial paper based upon a similar asset mix to the pension plan. Retired employees are also provided with a $10,000 dollar life insurance benefit.

The Company records the costs of postretirement benefits other than pensions (PBOP) during the employees' years of active service. Postretirement benefit expense recorded in 2021, 2020, and 2019, was $0.2 million, $5.2 million, and $7.9 million, respectively. The remaining net periodic benefit cost was $0.8 million at December 31, 2021, and is being recovered through future customer rates and is recorded as a regulatory asset.

The expected benefit payments, net of retiree premiums and Medicare Part D subsidies, are shown in the table below.

Benefit Plan Assets

The Company actively manages pension and PBOP trust (Plan) assets. The Company's investment objectives are:

•Maximize the return on the assets, commensurate with the risk that the Company deems appropriate to meet the obligations of the Plans, minimize the volatility of the pension expense, and account for contingencies;

•Generate a rate of return for the total portfolio that equals or exceeds the actuarial investment rate assumption;

Additionally, the rate of return of the total fund is measured periodically against an index comprised of 35% of the Standard & Poor's Index, 15% of the Russell 2000 Index, 10% of the MSCI EAFE Index, and 40% of the Bloomberg Barclays U.S. Aggregate Bond Index. The index is consistent with the Company's rate of return objective and indicates the Company's long-term asset allocation objective.

The Company applies a risk management framework for managing the risks associated with employee benefit plan trust assets. The guiding principles of this risk management framework are the clear articulation of roles and responsibilities, appropriate delegation of authority, and proper accountability and documentation. Trust investment policies and investment manager guidelines include provisions to ensure prudent diversification, manage risk through appropriate use of physical direct asset holdings and derivative securities, and identify permitted and prohibited investments.

The Company's target asset allocation percentages for major categories of the pension plan are reflected in the table below:


	Minimum Exposure		Target		Maximum Exposure
Fixed Income	25	%	40	%	55	%
Total Domestic Equity:	30	%	50	%	70	%
Small/Mid Cap Stocks	5	%	15	%	25	%
Large Cap Stocks	25	%	35	%	45	%
Non-U.S. Equities	5	%	10	%	15	%

The fixed income category includes money market funds, short-term bond funds, and cash. The majority of fixed income investments range in maturities from less than 1 to 5 years.

The Company's target allocation percentages for the PBOP trust is similar to the pension plan.

The Company uses the following criteria to select investment funds:

•Fund past performance;

•Fund meets criteria of Employee Retirements Income Security Act (ERISA);

•Timeliness and completeness of fund communications and reporting to investors;

•Stability of fund management company;

•Fund management fees; and

•Administrative costs incurred by the Plan.

Plan Fair Value Measurements

The fair value measurements standard establishes a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under the standard are described below:

Level 1—Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

Level 2—Inputs to the valuation methodology include:

•Quoted market prices for similar assets or liabilities in active markets;

•Quoted prices for identical or similar assets or liabilities in inactive markets;

•Inputs other than quoted prices that are observable for the asset or liability; and

•Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.

Level 3—Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The following tables present the fair value of plan assets by major asset category at December 31, 2021 and 2020:

_______________________________________________________________________________

1.The actuarial loss for pension and other benefits in 2021 was mainly due to an increase in the cost of living adjustment, the use of updated census data (pension benefits only), a higher rate of compensation increases (Pension benefits only), and an increase in the anticipated health care trend (Other benefits only) partially offset by actuarial gains due to a higher discount rate used in the calculation.

2.The short-term portion of the pension benefits was $2.1 million as of December 31, 2021 and December 31, 2020 and was recorded as part of other accrued liabilities on the Company's 2021 and 2020 Consolidated Balance Sheets.

Valuation Assumptions

Below are the actuarial assumptions used in determining the benefit obligation for the benefit plans:


	Pension Benefits				Other Benefits
	2021		2020		2021		2020
Weighted average assumptions as of December 31:
Discount rate - employee pension plan	3.28	%	3.08	%	—		—
Discount rate - SERP	3.18	%	2.97	%	—		—
Discount rate - other benefits	—		—		3.27	%	3.03	%
Long-term rate of return on plan assets	6.34	%	6.50	%	5.88	%	6.00	%
Rate of compensation increases - employee pension plan	4.25	%	4.00	%	—		—
Rate of compensation increases - SERP	5.00	%	5.00	%	—		—
Cost of living adjustment	2.20	%	2.10	%	—		—

For December 31, 2021 measurement purposes, the Company assumed a 5.4% annual rate of increase for 2021 in the per capita cost of covered benefits with rate decreasing to 5.2% by 2023, then gradually grading down to 3.9% over the next 38 years.

In 2020, the Company changed both the yield curve used to develop the discount rate and the method used to estimate the service and interest cost components of net periodic pension and benefit costs for 2021. The new yield curve used a higher-yielding subset of bonds that the Company believes will better approximate the rate at which the obligations could be effectively settled, currently. The change in the yield curve led to a decrease of $12.2 million and $1.2 million in net periodic pension cost and net periodic benefit cost for 2021. The new method uses the spot rate approach to estimate the service and interest costs by applying the specific spot rates along the yield curve used to determine the benefit obligation to the relevant projected cash outflows. The change in method led to a decrease of $6.2 million and $1.1 million in net periodic pension cost and net periodic benefit cost for 2021. This change does not affect the measurement of the projected benefit obligation. The Company made this change to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows to the corresponding spot rates. The Company has accounted for this change as a change in accounting estimate and accordingly has accounted for it prospectively. In California, where the majority of the Company's

net periodic pension and benefit costs are recorded, a corresponding decrease to balancing account revenue was recorded in 2021 for the changes in yield curve and method as Cal Water has regulatory mechanism which mitigate changes in net periodic pension and benefits costs. For 2020, the service and interest cost components of net periodic pension and benefit costs were determined using a single-weighted average discount rate.

The long-term rate of return assumption is the expected rate of return on a balanced portfolio invested roughly 60% in equities and 40% in fixed income securities. Returns on equity investments were estimated based on estimates of dividend yield and real earnings added to a 2.20% long-term inflation rate. For the pension plans, the assumed returns were 7.89% for domestic equities and 8.73% for foreign equities. For the other benefits plan, the assumed returns was 7.65% for domestic equities. Returns on fixed-income investments were projected based on investment maturities and credit spreads added to a 2.20% long-term inflation rate. For the pension and other benefit plans, the assumed returns were 3.34% for fixed income investments and 2.35% for short-term cash investments. The Company is using a long-term rate of return of 6.34% for the pension plan and 5.88% for the other benefit plan.

In 2021, the Company used the Society of Actuaries' Pri-2012 Total Dataset Mortality Tables for private-sector retirement plans in the United States and Mortality Improvement Scale (MP-2021) with adjustments to long-term improvements for measuring retirement plan obligations.

Components of Net Periodic Benefit Cost

Net periodic benefit costs for the pension and other postretirement plans for the years ended December 31, 2021 and 2020, included the following components:


	Pension Plan						Other Benefits
	2021		2020		2019		2021		2020		2019
Service cost	$	35,055	$	36,002	$	26,718	$	6,072	$	7,945	$	7,475
Interest cost	21,667		25,741		26,966		3,217		4,305		5,441
Expected return on plan assets	(39,472)		(33,086)		(30,285)		(8,769)		(7,236)		(5,794)

Net periodic benefit cost	$	27,253	$	45,684	$	34,374	$	227	$	5,211	$	7,880

Service cost portion of the pension plan and other postretirement benefits is recognized in administrative and general within the Consolidated Statements of Income. Other components of net periodic benefit costs include interest costs, expected return on plan assets, amortization of prior service costs, and recognized net actuarial loss and are reported together as other components of net periodic benefit cost within the Consolidated Statements of Income.

Below are the actuarial assumptions used in determining the net periodic benefit costs for the benefit plans, which uses the end of the prior year as the measurement date:

The health care cost trend rate assumption has a significant effect on the amounts reported. For 2021 measurement purposes, the Company assumed a 5.4% annual rate of increase in the per capita cost of covered benefits with the rate decreasing to 5.0% by 2023, then gradually grading down to 3.8% by 2060.

The Company intends to make annual contributions that meet the funding requirements of ERISA. The Company estimates in 2022 that the annual contribution to the pension plans will be $16.1 million and the annual contribution to the other postretirement plan will be $0.7 million.

13 STOCK-BASED COMPENSATION PLANS

The Company's equity incentive plan was approved and amended by stockholders on April 27, 2005 and May 20, 2014. The Company is authorized to issue awards up to 2,000,000 shares of common stock.

During 2021, the Company granted RSAs of common stock to Officers and to the Board of Directors. An RSA share represents the right to receive a share of the Company's common stock and is valued based on the fair market value of the Company's common stock at the date of grant. RSAs granted to Officers vest over 36 months with the first year cliff vesting. In general, RSAs granted to Board of Directors vest at the end of 12 months. The RSAs are recognized as expense evenly over 36 months for the shares granted to Officers and 12 months for the shares granted to Board of Directors. As of December 31, 2021, there was approximately $1.6 million of total unrecognized compensation cost related to RSAs. The cost is expected to be recognized over a weighted average period of 1.59 years.

A summary of the status of the outstanding RSAs as of December 31, 2021 is presented below:


	Number of RSA Shares	Weighted-Average Grant-Date Fair Value
RSAs at January 1, 2021	51,561	$	50.92
Granted	50,981	$	53.92
Vested	(39,851)	$	50.72
RSAs at December 31, 2021	62,691	$	53.49

During 2021, the Company granted performance-based RSUs of common stock to Officers. Each award reflects a target number shares of common stock that may be issued to the award recipient. The 2021 awards may be earned upon the completion of a 3-year performance period. Whether RSUs are earned at the end of the performance period will be determined based on the achievement of certain performance objectives set by the Board of Directors Compensation Committee in connection with the issuance of the RSUs. The performance objectives are based on the Company's business plan covering the performance period. The performance objectives include achieving the budgeted return on equity, budgeted investment in utility plant, customer service standards, employee safety standards and water quality standards. Depending on the results achieved during the 3-year performance period, the actual number of shares that a grant recipient receives at the end of the performance period may range from 0% to 200% of the target shares granted, provided that the grantee is continuously employed by the Company through the vesting date. If prior to the vesting date employment is terminated by reason of death, disability or normal retirement, then a pro rata portion of this award will vest. RSUs are not included in diluted shares until earned. The RSUs are recognized as expense ratably over the 3-year performance period using a fair market value of the Company's common share at the date of grant and an estimated number of RSUs earned during the performance period. As of December 31, 2021, there was approximately $2.0 million of total unrecognized compensation cost related to RSUs. The cost is expected to be recognized over a weighted average period of 1.22 years.

14 FAIR VALUE OF FINANCIAL INSTRUMENTS

The accounting guidance for fair value measurements and disclosures provides a single definition of fair value and requires certain disclosures about assets and liabilities measured at fair value. A hierarchical framework for disclosing the observability of the inputs utilized in measuring assets and liabilities at fair value is established by this guidance. The three levels in the hierarchy are described in Note 12 - Employee Benefit Plans.

Specific valuation methods include the following:

Cash, Accounts receivable, short-term borrowings, and accounts payable carrying amounts approximated the fair value because of the short-term maturity of the instruments.

Long-term debt fair values were estimated using the published quoted market price, if available, or the discounted cash flow analysis, based on the current rates available using a risk-free rate (a U.S. Treasury securities yield curve) plus a risk premium of 0.6%.

Commitments

Water Supply Contracts

The Company has long-term commitments to purchase water from water wholesalers. The commitments are noted in the table below.


	Water Supply Contracts*
2022	$	33,858
2023	33,858
2024	33,856
2025	33,856
2026	33,860
Thereafter	499,336

_______________________________________________________________________________

* Estimated annual contractual obligations are based on the same payment levels as 2021.

Water Supply Contracts

The Company has a long-term contract with the Santa Clara Valley Water District that requires the Company to purchase minimum annual water quantities. Purchases are priced at the districts then-current wholesale water rate. The Company operates to purchase sufficient water to equal or exceed the minimum quantities under the contract. The total paid to Santa Clara Valley Water District was $11.9 million in 2021, $15.2 million in 2020, and $13.6 million in 2019.

The Company also has a water supply contract with Stockton East Water District (SEWD) that requires a fixed monthly payment. Each year, the fixed monthly payment is adjusted for changes to SEWD's costs. The total paid under the contract was $12.9 million in 2021, $14.3 million in 2020, and $13.3 million in 2019.

On September 21, 2005, the Company entered into an agreement with Kern County Water Agency (Agency) to obtain treated water for the Company's operations. The term of the agreement is to January 1, 2035, or until the repayment of the Agency's bonds (described hereafter) occurs. Under the terms of the agreement, the Company is obligated to purchase approximately 20,500 acre feet of treated water per year. The Company is obligated to pay the Capital Facilities Charge and the Treated Water Charge regardless of whether it can use the water in its operation, and is obligated for these charges even if the Agency cannot produce an adequate amount to supply the 20,500 acre feet in the year. This agreement supersedes a prior agreement with Kern County Water Agency for the supply of 11,500 acre feet of water per year.

Three other parties, including the City of Bakersfield, are also obligated to purchase a total of 32,500 acre feet per year under separate agreements with the Agency. Further, the Agency has the right to proportionally reduce the water supply provided to all of the participants if it cannot produce adequate supplies. If any of the other parties does not use its allocation, that party is obligated to pay its contracted amount.

If any of the parties were to default on making payments of the Capital Facilities Charge, then the other parties are obligated to pay for the defaulting party's share on a pro-rata basis. If there is a payment default by a party and the remaining parties have to make payments, they are also entitled to a pro-rata share of the defaulting party's water allocation.

The Company expects to use all its entitled water in its operations every year. In addition, if the Company were to pay for and receive additional amounts of water due to a default of another participating party; the Company believes it could use this additional water in its operations without incurring substantial incremental cost increases. If additional treated water is available, all parties have an option to purchase this additional treated water, subject to the Agency's right to allocate the water among the parties.

15 COMMITMENTS AND CONTINGENCIES (Continued)

The total obligation of all parties, excluding the Company, is approximately $82.4 million to the Agency. Based on the credit worthiness of the other participants, which are government entities, it is believed to be highly unlikely that the Company would be required to assume any other parties' obligations under the contract due to their default.

The Company pays a capital facilities charge and charges related to treated water that together total $10.6 million annually, which equates to $517.91 dollars per acre foot. Total treated water charge for 2021 was $4.0 million. As treated water is being delivered, the Company will also be obligated for the Company's portion of the operating costs; that portion is currently estimated to be $85.65 dollars per acre foot. The actual amount will vary due to variations from estimates, inflation, and other changes in the cost structure. Our overall estimated cost of $517.91 dollars per acre foot is less than the estimated cost of procuring untreated water (assuming water rights could be obtained) and then providing treatment.

Leases

The Company has operating and finance leases for water systems, offices, land easements, licenses, equipment, and other facilities. The leases generally have remaining lease terms of 1 year to 50 years, some of which include options to extend the lease for up to 25 years. The exercise of lease renewal options is at the Company’s sole discretion. Most of the Company’s lease agreements contain mutual termination options that require prior written notice by either lessee or lessor. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. Certain leases include options to purchase the leased property. The depreciable life of the assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option that is reasonably certain of exercise. Leases with an initial term of 12 months or less are not recorded on the balance sheet as the Company applied the short-term lease exception allowed by the FASB guidance. Lease expense for these leases is recognized on a straight-line basis over the lease term. A subset of the Company’s leases contains variable lease payments that depend on changes in the CPI.

The Company determines if an arrangement is a lease at contract inception. Generally, a lease agreement exists if the Company determines that the arrangement gives the Company control over the use of an identified asset and obtains substantially all of the benefits from the identified asset.

The right-of-use (ROU) assets that are recorded represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company’s operating leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The ROU asset and lease liability may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Variable lease payments that are based on changes in CPI are included in the measurement of ROU asset and lease liability on the basis of the rate at lease commencement. Subsequent changes to the payments as a result of changes to the CPI rate are recognized in the period in which the obligation of these payments is incurred.

Contingencies

Groundwater Contamination

The Company has undertaken litigation against third parties to recover past and future costs related to ground water contamination in our service areas. The cost of litigation is expensed as incurred and any settlement is first offset against such costs. The CPUC's general policy requires all proceeds from contamination litigation to be used first to pay transactional expenses, then to make customers whole for water treatment costs to comply with the CPUC's water quality standards.

CPUC allows for a risk-based consideration of contamination proceeds which exceed the costs of the remediation described above and may result in some sharing of proceeds with the shareholder, determined on a case by case basis. The CPUC has authorized various memorandum accounts that allow the Company to track significant litigation costs to request recovery of these costs in future filings and uses of proceeds to comply with CPUC's general policy.

As previously reported, Cal Water has filed with the City of Bakersfield, in the Superior Court of California, a lawsuit that names potentially PRPs, who manufactured and distributed products containing TCP in California. TCP has been detected in the ground water. The lawsuit seeks to recover treatment costs necessary to remove TCP. On December 20, 2017, Cal Water entered into an $85.0 million settlement agreement and release of claims with the PRPs, in California Water Service Company and City of Bakersfield v. The Dow Chemical Company, et al., Civil Case No. CIV-470999 (TCP Action). The TCP Action sought damages and other relief related to the PRPs’ alleged contamination of drinking water supply and water wells with the chemical TCP. The proceeds from the settlement, after payment of the legal fees, was $56.0 million and was used to reimburse a portion of the capital costs associated with Cal Water’s remediation efforts related to such alleged TCP contamination. As of December 31, 2021, Cal Water has used all of the proceeds on remediation efforts related to the alleged TCP contamination. Under the terms of the Agreement, the PRPs are released from all claims regarding 47 of the 57 total claimed wells, and Cal Water agreed to file a dismissal with prejudice of the TCP Action. The PRPs are also released from future claims regarding TCP contamination of any other wells, unless and until Cal Water has installed granular activated carbon filtration systems or other then-approved Sate treatment technology for TCP on, or replaced, 36 wells due to TCP contamination.

Other Legal Matters

From time to time, the Company is involved in various disputes and litigation matters that arise in the ordinary course of business. The status of each significant matter is reviewed and assessed for potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount of the range of loss can be estimated, a liability is accrued for the estimated loss in accordance with the accounting standards for contingencies. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on the best information available at the time. While the outcome of these disputes and litigation matters cannot be predicted with any certainty, management does not believe when taking into account existing reserves the ultimate resolution of these matters will materially affect the Company's financial position, results of operations, or cash flows. The Company has recognized a liability of $3.5 million for all known legal matters as of December 31, 2021 primarily due to potable water main leaks and other work related legal matters. The cost of litigation is expensed as incurred and any settlement is first offset against such costs. Any settlement in excess of the cost to litigate is accounted for on a case by case basis, dependent on the nature of the settlement.
