California Water Service Group 3 CALIFORNIA WATER SERVICE GROUP 1720 North First Street San Jose, CA 95112-4598 (408) 367-8200 Notice of Annual Meeting of Stockholders TIME 9:30 a.m. on Wednesday, April 26, 2006 PLACE Executive Offices of California Water Service Group, 1720 North First Street, San Jose, California ITEMS OF BUSINESS (1) To elect directors (2) To ratify the appointment of independent registered public accounting firm (3) To consider such other business as may properly come before the meeting RECORD DATE You are entitled to vote if you were a stockholder at the close of business on Monday, February 27, 2006. VOTING BY PROXY Please submit a proxy as soon as possible so that your shares can be voted at the meeting in accordance with your instructions. You may submit your proxy (1) over the Internet, (2) by telephone, or (3) by mail. For specific instructions, please refer to the Questions and Answers beginning on page 5 of this proxy statement and the instructions on the proxy card. By Order of the Board of Directors DAN L. STOCKTON Corporate Secretary This notice of meeting and proxy statement and accompanying proxy card are being distributed beginning on or about March 27, 2006. 4 California Water Service Group QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND THE ANNUAL MEETING What am I voting on? o Election of nine directors to serve until the 2007 Annual Meeting. o Ratification of the Audit Committee's selection of KPMG LLP as the Group's independent registered public accounting firm for 2006. Those elected to serve as the Group's directors also will serve as the directors of California Water Service Company and CWS Utility Services, two of the Group's operating subsidiaries. Who may attend the Annual Meeting? All Group stockholders may attend. Who is entitled to vote? Stockholders of record at the close of business on February 27, 2006 (the "Record Date"), or those with a valid proxy from a brokerage firm or another similar organization which held shares on the Record Date. How many votes do I get? Each share of common stock is entitled to one vote. Each share of preferred stock is entitled to 16 votes. You may also use "cumulative voting" in the election of directors. What is "cumulative voting" and how does it work? Stockholders or persons holding a valid proxy may "cumulate" their votes for the election of directors. That is, they may give one candidate nine votes for each common share owned. Instead of casting one vote for each of the nine candidates they may cast all nine votes for a single candidate or, they may distribute their votes on the same principle among as many candidates as they desire. Because each preferred share is entitled to 16 votes, preferred stockholders may cumulate 144 votes (16 x 9) for each share owned. If you do not indicate otherwise, the proxies may use their discretion to cumulate votes. How are the directors elected? The nine nominees receiving the highest number of votes are elected to the Board. Common and preferred shares vote together on directors. Who are the Board's nominees? The nominees are Douglas M. Brown, Robert W. Foy, Edward D. Harris, Jr., M.D., Bonnie G. Hill, David N. Kennedy, Richard P. Magnuson, Linda R. Meier, Peter C. Nelson, and George A. Vera. All the nominees are current Board members. See pages 13-15 for biographical information, including the nominees' current directorships in other publicly held companies. What is the required vote for the second proposal to pass? In order for the Audit Committee's selection of KPMG LLP as independent registered public accounting firm to be ratified, the proposal must receive the affirmative vote of a majority of the shares present in person or represented by proxy and entitled to vote at the meeting. How do I vote? You may vote by mail. You do this by signing the proxy card and mailing it in the enclosed, prepaid and addressed envelope. If you mark your voting instructions on the proxy card, your shares will be voted as you instruct. You may vote by telephone. You do this by following the "Vote by Telephone" instructions on the proxy card. If you vote by telephone, you do not have to mail in your proxy card. You must have a touch-tone phone to vote by telephone. California Water Service Group 5 QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND THE ANNUAL MEETING You may vote on the Internet. You do this by following the "Vote by Internet" instructions on the proxy card. If you vote on the Internet, you do not have to mail in your proxy card. You may vote in person at the meeting. We will hand out written ballots to anyone who wants to vote at the meeting. If you hold your shares in street name, you must request a legal proxy from your stockbroker in order to vote at the meeting. If you return a signed card but do not provide voting instructions, your shares will be voted: o for the nine named director nominees o for the ratification of the selection of independent registered public accounting firm We have been advised by counsel that these telephone and Internet voting procedures comply with Delaware law. What if I change my mind after I return my proxy? You may revoke your proxy any time before the polls close at the meeting. You may do this by: o signing another proxy with a later date, o voting by telephone or on the Internet (your latest telephone or Internet proxy is counted), o voting again at the meeting, or o notifying the Corporate Secretary, in writing, that you wish to revoke your previous proxy. We must receive your notice prior to the vote at the Annual Meeting. Will my shares be voted if I do not return my proxy? If you are a stockholder of record (that is, you hold your shares in your own name), your shares will not be voted unless you attend the meeting and vote in person. Different rules apply if your stockbroker holds your shares for you. What happens if my shares are held by my stockbroker? Your stockbroker, under certain circumstances, may vote your shares. Stockbrokers must write to you asking how you want your shares voted. However, if you do not respond, stockbrokers have authority under exchange regulations to vote your unvoted shares on certain "routine" matters, including election of directors and ratification of the selection of the independent registered public accounting firm. If you wish to change voting instructions you give to your stockbroker, you must ask your stockbroker how to do so. If you do not give your stockbroker voting instructions, the stockbroker may either: o proceed to vote your shares on routine matters and refrain from voting on nonroutine matters, or o leave your shares entirely unvoted. Shares that your stockbroker does not vote ("stockbroker non-votes") will count towards the quorum only. We encourage you to provide your voting instructions to your stockbroker. This ensures that your shares will be voted at the meeting. You may have granted to your stockbroker discretionary voting authority over your account. If so, your stockbroker may be able to vote your shares even on nonroutine matters, depending on the terms of the agreement you have with your stockbroker. What happens if I abstain from voting on a proposal? If you abstain from voting on a proposal (either by proxy or in person at the Annual Meeting), your shares will be counted in determining whether we have a quorum, but the abstention will have the same effect as a vote against a proposal. Who will count the vote? Representatives of American Stock Transfer and Trust Co., our transfer agent, will serve as the inspector of elections and count the votes. 6 California Water Service Group QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND THE ANNUAL MEETING What does it mean if I get more than one proxy card? It means that you have multiple accounts at the transfer agent and/or with stockbrokers. Please sign and return all proxy cards to ensure that all your shares are voted. What constitutes a quorum? A majority of the outstanding shares--present at the Annual Meeting or represented by persons holding valid proxies--constitutes a quorum. If you submit a valid proxy card, your shares will be part of the quorum. Without a quorum, no business may be transacted at the Annual Meeting. However, whether or not a quorum exists, a majority of the voting power of those present at the Annual Meeting may adjourn the Annual Meeting to another date, time and place. At the Record Date, there were 3,024 stockholders of record. There were 18,405,138 shares of our common stock outstanding and entitled to vote at the Annual Meeting and 139,000 shares of our preferred stock outstanding and entitled to vote at the Annual Meeting. What percentage of stock do the directors and executive officers own? Together, they own less than one percent of our common and preferred stock. See page 16 for more details. Who are the largest common stockholders? As of January 1, 2006, the largest principal stockholder was SJW Corp., which held 1,099,952 shares of common stock, representing 6%. To the best of our knowledge, no other stockholders held over 5% of our common shares. See page 17 for more details. What is the deadline for submitting stockholder proposals for the Group's proxy materials for next year's Annual Meeting? Any proposals which stockholders intend to present at the 2007 Annual Meeting of stockholders must be received by the Corporate Secretary of the Group by November 27, 2006 in order to be considered for inclusion in the Group's 2007 proxy materials. A proposal and any supporting statement together may not exceed 500 words. Please submit the proposal to Dan L. Stockton, Corporate Secretary, California Water Service Group, 1720 North First Street, San Jose, California 95112-4598. How can a stockholder propose a nominee for the Board? Any stockholder of record who is entitled to vote at a stockholders' meeting may propose a nominee for the Board. The bylaws contain the requirements for doing so. Contact the Corporate Secretary to request a copy of the full bylaw requirements. Briefly, a stockholder must give timely prior notice to the Group. The notice must be received by the Corporate Secretary at the Group's principal place of business by the 150th day before the first anniversary of the prior year's Annual Meeting. If we move the date of the meeting by more than thirty days before or more than sixty days after the date of the previous meeting, notice is due by the 150th day before the Annual Meeting or the 10th day after we publicly announce the holding of the meeting. If the Board calls a special meeting to elect directors, stockholder notice is due by the 150th day prior to that meeting or the 10th day after we publicly announce the holding of the special meeting and identify the Board's director nominees. The bylaws do not affect the rights of preferred holders to nominate directors where they are otherwise entitled to do so. The bylaws specify what the notice must contain. The notice deadline for the 2007 Annual Meeting is November 27, 2006. California Water Service Group 7 QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND THE ANNUAL MEETING How can a stockholder propose business at a stockholders' meeting? Any stockholder of record who is entitled to vote at a stockholders' meeting may propose business for the meeting. Just as with nominations, the bylaws contain the requirements. Contact the Corporate Secretary and request a copy of the full bylaw requirements. The stockholder must give timely prior notice to the Group. The deadlines are the same as for stockholder nominations discussed above. If the Group's Secretary receives a proposal after that deadline it will be considered untimely, and the persons named in the proxy for the 2007 meeting may exercise their discretion in voting with respect to the proposal. The bylaws specify what the notice must contain. Stockholders must comply with all requirements of the securities laws regarding proposals. The bylaws do not affect any stockholder right to request inclusion of proposals in the Group's proxy statement under the rules of the Securities and Exchange Commission. Because of the 150-day notice requirement discussed above, stockholders who have not given prior notice may not raise a proposal (or a nomination) at this year's meeting. How can a stockholder or other interested party contact the independent directors, the director who chairs the Board's executive sessions or the full Board? Stockholders or other interested parties may address inquiries to any of the Group's directors, to the director who chairs of the Board's executive sessions, or to the full Board, by writing to Dan L. Stockton, Corporate Secretary, California Water Service Group, 1720 North First Street, San Jose, California 95112-4598. All such communications are sent directly to the intended recipient. Can I make comments and/or ask questions during the Annual Meeting? Yes, most certainly. Stockholders wishing to address the meeting are welcome to do so by adhering to the following guidelines: 1. Stockholders may address the meeting when recognized by the Chairman or President and Chief Executive Officer. 2. Each stockholder, when recognized, should stand and identify himself or herself. 3. Stockholder remarks must be limited to matters before the meeting and may not exceed 2 minutes in duration per speaker. No cameras, video or recording equipment will be permitted at the meeting. 8 California Water Service Group BOARD STRUCTURE This section briefly describes the structure of the board and the functions of the principal committees of the Board. The charters for the Audit, Compensation, Finance and Nominating/Corporate Governance committees are posted on the Group's website at http://www.calwatergroup.com. The Audit Committee charter is also attached as Appendix A to this proxy statement. The charters are also available in written form upon request to Dan L. Stockton, Corporate Secretary, California Water Service Group, 1720 North First Street, San Jose, California 95112-4598. The Group's policy is that all directors must be able to devote the required time to carry out director responsibilities and should attend all meetings of the Board and of Committees on which they sit. Committees: AUDIT: Reviews the Group's auditing, accounting, financial reporting and internal audit functions. Also, the Committee is directly responsible for the appointment, compensation and oversight of the independent registered public accounting firm, although stockholders are asked to ratify the Committee's selection. All members are nonemployee directors, are independent as defined in the listing standards of the New York Stock Exchange and meet the additional independence requirements for audit committee members imposed by the Sarbanes-Oxley Act and the rules of the SEC thereunder. The Group has not relied on any exemptions in the SEC's rules from the audit committee independence requirements. The Board has determined that George A. Vera, chair of the Audit Committee, is a financial expert and is independent as defined in the rules of the SEC and in the listing standards of the New York Stock Exchange. This means that the Board believes Mr. Vera has: (i) an understanding of generally accepted accounting principles and financial statements; (ii) the ability to assess the general application of such principles in connection with the accounting for estimates, accruals and reserves; (iii) experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the Group's financial statements, or experience actively supervising one or more persons engaged in such activities; (iv) an understanding of internal control over financial reporting; and (v) an understanding of Audit Committee functions. Designation of a person as an audit committee financial expert does not result in the person being deemed an expert for any purpose, including under Section 11 of the Securities Act of 1933. The designation does not impose on the person any duties, obligations or liability greater than those imposed on any other audit committee member or any other director and does not affect the duties, obligations or liability of any other member of the Audit Committee or Board of Directors. COMPENSATION: Reviews the Group's executive and Director compensation, employee benefit plans and programs, including their establishment, modification and administration. All members are nonemployee directors and independent as defined in the listing standards of the New York Stock Exchange. FINANCE: Assists the Board in reviewing the Group's financial policies, strategies and capital structure, and makes reports and recommendations to the Board as the Committee deems advisable. All members are nonemployee directors and independent as defined in the listing standards of the New York Stock Exchange. NOMINATING/CORPORATE GOVERNANCE: Assists the Board by (i) identifying candidates and nominating individuals qualified to become Board members and (ii) developing and recommending a set of corporate governance principles applicable to the Group. All members are nonemployee directors and are independent as defined in the listing standards of the New York Stock Exchange. EXECUTIVE: Has limited powers to act on behalf of the Board whenever it is not in session. This Committee meets only as needed. The Committee consists of two nonemployee directors and two employee directors. During 2005, there were 11 regular meetings of the Board, six meetings of the Audit Committee, two meetings of the Compensation Committee, two meetings of the Finance Committee, one meeting of the Nominating/Corporate Governance Committee and no meeting of the Executive Committee. Each of the California Water Service Group 9 director-nominees who served on the Board of California Water Service Group in 2005 attended at least 93% of all Board and applicable committee meetings. Collectively, they attended an average of 99% of all of the Board and applicable committee meetings. Independence of Directors The Board has adopted a standard of director independence. The standard determines that a director is independent if he or she has no material relationship, whether commercial, industrial, banking, consulting, accounting, legal, charitable or familial, with the Group, either directly or indirectly as a partner, stockholder or officer of an entity that has a material relationship with the Group. A director is not independent if he or she fails the standard for independence in Section 303A of the New York Stock Exchange Listed Company Manual or the Group's independence standards. The following relationships or transactions disqualify a person from being considered independent under the Exchange's standards o receipt during any twelve-month period within the past three years by the person, or by an immediate family member of the person, of more than $100,000 in direct compensation from the Group, other than director or committee fees and pension or other forms of deferred compensation for prior service; o the director or an immediate family member is a current partner of the Group's internal or external auditor; the director is a current employee of such a firm; the director's immediate family member is a current employee of such a firm who participates in the firm's audit, assurance or tax compliance practice or the director or an immediate family member was in the last three years a partner or employee of such a firm and personally worked on the Group's audit; o employment of the director or of an immediate family member within the last three years as an executive officer of a company whose compensation committee includes an executive officer of the Group; o being an employee or having an immediate family member who is an executive officer of a customer or vendor or other party which has made payments to or received payments from the Group of at least 2% or $1 million, whichever is greater, of the party's consolidated gross revenues, in any of the past three years. The Board has determined that none of the following relationships, in itself, is material for purposes of these standards: o being a residential customer of the Group; o being an executive officer or employee, or being otherwise affiliated with, a commercial customer from which Cal Water's consolidated gross revenues in any of the last three years are or were not more than the greater of (i) 1% of Cal Water's consolidated gross revenues for the year or (ii) $500,000; o being an executive officer or employee of a supplier or vendor that has or had consolidated gross revenues from the Group in any of the last three years of not more than the lesser of (i) 1% of Cal Water's consolidated gross revenues for the year or (ii) $500,000; o having a 5% or greater ownership interest or similar financial interest in a supplier or vendor that has or had consolidated gross revenues from the Group in any of the last three years of not more than the lesser of (i) 1% of Cal Water's consolidated gross revenues for such year or (ii) $500,000; o being a director of any of the Group's subsidiaries. If a director is eligible for treatment as an independent director under Section 303A but has a relationship with the Group other than one of the five relationships described above, the Board of Directors or the Nominating/Corporate Governance Committee will review the facts and circumstances of the relationship and make a good faith determination whether it considers the director independent in light of the purposes of the Sarbanes-Oxley Act of 2002 and the New York Stock Exchange Listing standards and, if it determines that the director is independent, will disclose the basis for its determination in the Group's proxy statement for its next Annual Meeting of stockholders as required by applicable laws and regulation. In making a determination regarding independence of a director, the Board of Directors will consider, among other things, the materiality of the relationship to the Group, to the director, and, if applicable, to the organization with which the director is affiliated. The Board has determined that a majority of the members of the Board meet the standard and also are "independent," as defined in the listing standards of the New York Stock Exchange. 10 California Water Service Group Director Qualifications The Group seeks directors with the following specific qualifications: o shows evidence of leadership in his/her particular field; o has broad experience and exercises sound business judgment; o has expertise in an area of importance to Group and its subsidiaries; o is able to work in a collegial Board environment; o has the highest personal and professional ethics and integrity; o is able to devote the required time to carry out director responsibilities; o has the ability and willingness to contribute special competencies to Board activities, to include appointment to Board committees; o is free from conflicts of interest which would interfere with serving and acting in the best interests of the Group and its stockholders; o is the highest caliber individual who has achieved a level of prominence in his or her career; for example, a CEO or highest level financial officer of a sizeable corporation, a director of a major corporation, a prominent civic or academic leader, etc. In addition, Section 2.8 of the Group's bylaws contains requirements which a person must meet to avoid conflicts of interest which would disqualify that person from serving as a director. Identification of Director Nominees The Group identifies new director candidates by director recommendations and by the use of search firms selected by the Nominating/Corporate Governance Committee. The Group considers nominees of stockholders in the same manner as all other nominees. The Group will consider director nominees recommended by stockholders who adhere to the procedure described under "Questions and Answers About the Proxy Materials and the Annual Meeting--How can a stockholder propose a nominee for the Board?" on page 7. Executive Sessions of the Board As required by the listing standards of the New York Stock Exchange, the Group schedules regular executive sessions of directors in which directors meet without management participation. Mr. Douglas M. Brown has been appointed to chair these sessions. Corporate Governance Guidelines The Board has adopted corporate governance guidelines as defined by the listing standards of the New York Stock Exchange. The guidelines are posted on the Group's website at http://www.calwatergroup.com. The guidelines are also available in written form upon request to Dan L. Stockton, Corporate Secretary, California Water Service Group, 1720 North First Street, San Jose, California 95112-4598. California Water Service Group 11 Director Compensation Arrangements The following table provides information on the Group's compensation and reimbursement practices during fiscal year 2005 for nonemployee directors, as well as the range of compensation paid to nonemployee directors who served during the 2005 fiscal year. Directors who are employed by the Group receive no compensation for their Board activities except a fee for attending each Board meeting. Directors receive no additional compensation for serving on the Boards of the Group's subsidiaries. Director Compensation Table For Fiscal Year 2005 Annual Director Retainer $22,000 Board and Committee Meeting Attendance Fee $1,400 Committee Meeting Attendance Fee for Committee Chairs $2,800 Range of Committee Meeting Attendance Fees Paid to Directors $4,200 - $18,200 Compensation. In 2005, each director received an annual retainer of $22,000. Effective January 1, 2006, nonemployee directors are paid an annual retainer of $23,500 and a meeting attendance fee of $1,500, and nonemployee committee chairs are paid a meeting attendance fee of $3,000. The Audit Committee Chair is paid an annual retainer of $8,500. Deferred Compensation Plan. The Group has established the California Water Service Group Deferred Compensation Plan, an unfunded deferred compensation program for nonemployee directors, executive officers and managers. Under the plan, nonemployee directors may defer up to 100% of their annual retainer with a minimum annual deferral of $5,000. The plan also allows nonemployee directors to defer 100% of their meeting and committee meeting fees. Directors who are also executive officers may defer 100% of their meeting fees and up to 50% of their annual salary with a minimum annual deferral of $5,000. Other executive officers and managers who elect to participate in the plan may defer up to 50% of their annual salary, with a minimum deferral of $5,000. Amounts deferred are fully vested and recorded by the Group as general liabilities and the value of deferrals fluctuate according to one of several investment indices selected by the participant. Funds are distributed from this plan when the participant ceases to be a director (unless the participant is an employee, in which case distribution occurs when employment terminates). Distributions also are available upon a showing of hardship. Amounts remaining undistributed at death are distributed to the participant's designated beneficiary or beneficiaries. The Group is under no obligation to make any investment or otherwise fund the plan. Participants are general, unsecured creditors of the Group. Retirement Age of Directors. The Group has established a mandatory retirement age for directors. A director must retire no later than the Annual Meeting that follows the date of the director's 75th birthday. An employee director must retire as an employee or a director no later than the Annual Meeting that follows the date of the director's 70th birthday. Director Retirement Plan. Any current nonemployee director who retires subsequent to February 22, 2006, after serving on the Board for a total of five or more years will receive a retirement benefit equivalent to $22,000 per year. This benefit will be paid for the number of years the director served on the Board, up to 10 years. Retirement benefit payments will be made monthly at the same time as retainer payments are made to active directors. In December 2005, the Director Retirement Plan was cancelled for future directors. Annual Meeting Attendance. All directors are expected to attend each Annual Meeting of the Group's stockholders, unless attendance is prevented by an emergency. Except for Linda R. Meier, all of the Group's directors who were in office at that time attended the Group's 2005 Annual Meeting of stockholders. 12 California Water Service Group PROPOSAL NO. 1--ELECTION OF DIRECTORS There are nine nominees for election to our Board this year.

These agreements provide officers with severance payments of approximately three times their annual salary if the Group merges with another company or effects another transaction by which another company acquires control and as a result, within 24 months, these officers lose their executive positions. This severance amount would be paid in three equal annual payments, beginning the month following termination. 18 California Water Service Group SEPARATION AGREEMENT Richard D. Nye, former Chief Financial Officer of the Company, submitted his resignation from the Company effective October 27, 2005. Mr. Nye's Separation Agreement and Release dated as of December 15, 2005, provides, among other terms, as follows: o payment to Mr. Nye, previously made on October 28, 2005, of final salary through October 27, 2005, plus six weeks unused vacation, and one week salary as termination wages; o payment in the amount of $137,500 minus applicable tax withholding, equivalent to six months' salary, payable upon Mr. Nye's request made by March 31, 2006; o continuing entitlement to any benefits accrued as of October 27, 2005, under the Company's pension plan, supplemental executive retirement plan, and deferred compensation plan. Mr. Nye was hired on March 1, 2003, and as such, has not vested in the pension or supplemental executive retirement plan under the vesting terms of the respective plans. Benefits accrued Mr. Nye under the deferred compensation plan were solely contributed to the plan by Mr. Nye; o payment of Mr. Nye's current medical insurance premiums for 12 months in the aggregate amount of $6,795, less tax withholding; o allowing Mr. Nye to purchase a Company-owned, 2003 Toyota Avalon automobile, at a price of $17,000, which was more than trade-in value; and o the agreement also contains a release of any liability of the Company to Mr. Nye.

California Water Service Group 19 EQUITY COMPENSATION PLAN INFORMATION The following table sets forth information about the number of options previously granted and outstanding and the number available for future grants. The number of securities issuable upon exercise reflects options outstanding under the former Long-Term Incentive Plan. That plan was replaced by the Group's Equity Incentive Plan, which was approved by the stockholders at their Annual Meeting held on April 27, 2005. The number of securities remaining available for future issuance reflects shares available for grant under the Equity Incentive Plan as of December 31, 2005, the end of the Group's last fiscal year.
(c) (a) (b) Number of securities remaining Number of securities to be Weighted-average available for future issuance issued upon exercise of exercise price of under equity compensation outstanding options, outstanding options, plans (excluding securitie Plan category warrants and rights warrants and rights reflected in column (a)) - ------------------------------------------------------------------------------------------------------------------------ Equity compensation plans 98,000 $ 24.95 1,000,000 approved by stockholders - ------------------------------------------------------------------------------------------------------------------------ Equity compensation plans not None None None approved by stockholders - ------------------------------------------------------------------------------------------------------------------------ Total 98,000 $ 24.95 1,000,000 (1) - ------------------------------------------------------------------------------------------------------------------------
(1) On January 4, 2006, the Group granted stock appreciation rights (37,500 shares) and restricted stock (9,142 shares) under the Equity Incentive Plan, which reduces the number of shares available for future grant to 953,358 shares. PENSION PLANS The table1 that follows shows the estimated annual benefits the Group must pay upon retirement to executive officers under the Group's Pension Plan and Supplemental Executive Retirement Plan ("SERP"). The SERP is designed to provide executive officers a pension benefit which when combined with the regular pension plan benefit would equal the pension benefit that would be provided if the regular Pension Plan's benefit were unaffected by the federal tax law restrictions on retirement plan benefits. The years of service required to earn maximum benefit under the SERP is 15 years.

The benefits are not subject to any deductions for Social Security or other offset amounts. (2) Compensation includes salary as set forth in the Summary Compensation Table. The number of years of credited service at January 1, 2006, for officers named in the Compensation Table is as follows: Mr. Nelson, 25; Mr. Foy, 25; Mr. Ferraro, 16; Mr. Nye, 2; and Mr. Guzzetta, 28. Because Mr. Nye had not vested in the Group's Pension Plan and SERP at the time he left the Group, he is not entitled to benefits under either of these two plans. 20 California Water Service Group REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION What is this report? The Securities and Exchange Commission requires that public companies disclose the policies that the Group uses to establish executive officer compensation. This report explains the criteria that the Group used to determine the compensation of all of its officers in 2005. What are the Compensation Committee's responsibilities? The Committee is responsible for establishing and implementing policies and programs to compensate Group executives and Directors. Each November, the Committee reviews and recommends compensation levels for all executive officers for the 12-month period beginning January 1. The Committee then submits its recommendations to the entire Board. In 2005, the Board adopted the Committee's recommendations without modification. During 2005, the Committee met twice. What is our compensation philosophy? The primary objectives of our executive compensation program are: 1) To attract, retain, and motivate talented and experienced executives; 2) To reward excellent job performance and contributions to the Group's future success; 3) To provide fair and reasonable compensation. The Compensation Committee believes that compensating executives by use of these criteria leads to excellent executive performance, which benefits stockholders and ratepayers alike. When making its recommendations, the Committee takes into account that the California Public Utilities Commission ("CPUC") reviews the compensation decisions of the Group's officers for reasonableness. Furthermore, as a regulated utility, the Group's financial performance is to a large extent dependent upon CPUC ratemaking decisions and other factors beyond management's control, such as weather. Therefore, the Committee's decisions are determined largely by its evaluation of factors that are within management's control. Who serves on the Compensation Committee? The Compensation Committee is composed of Dr. Harris (Committee Chair), Ms. Hill, Mr. Kennedy, Mr. Magnuson and Ms. Meier. All members of the Compensation Committee meet the independence standard adopted by the Board and the New York Stock Exchange standard for independence. How is executive compensation determined? When examining the annual compensation of individual executives, the Committee considers the officer's duties, performance and contribution to the Group's current and future success. The Committee also considers the officer's experience, tenure, value to the Group, prior salary adjustments and the inflation rate. In order to set salaries for the Group's officers at competitive and reasonable levels, the Committee annually reviews the compensation of officers of other major water companies. The Committee factors into its analysis the Group's comparatively low number of officers and its limited methods of compensation. Mr. Nelson's Compensation. In November 2004, the Committee reviewed the compensation for Peter C. Nelson, president and chief executive officer. The Committee set Mr. Nelson's 2005 compensation using the same factors that it used to set the compensation of the other Group executives. California Water Service Group 21 REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION Does the Group have a Long-Term Incentive Plan? Yes. Stockholders of the Group approved an Equity Incentive Plan at the April 27, 2005 Annual Meeting. This plan replaced the former Long-Term Incentive Plan which was approved by the stockholders at the April 19, 2000, meeting. The plan allows the Group to offer competitive compensation to assist in recruiting and retaining top-performing individuals. The plan also aligns the interests of stockholders and participants. Finally, the plan provides the potential to link benefits to the Group's achievement of stockholder, customer and other performance goals, giving participants an incentive to achieve these goals. Who determines the amount and type of award granted? The Equity Incentive Plan is administered by the Board of Directors of the Group. The Board has the power to construe and interpret the plan and, subject to the provisions of the plan, to determine the persons to whom and the dates on which awards will be granted, the number of shares to be subject to each award, the time or times during the term of each award within which all or a portion of the award may be exercised, the exercise price, the type of consideration, and other terms of the award. The Board of Directors is authorized to delegate administration of the Equity Incentive Plan to a committee composed of one or more of its members. The Board of Directors also is authorized to delegate to one or more officers of the Group the authority to designate employees of the Group or its affiliates to whom stock awards will be granted (other than themselves), and to determine the number of shares to be subject to that award. The Board of Directors has delegated administration of the Equity Incentive Plan to the Compensation Committee of the Board of Directors. As used in this proxy statement with respect to the Equity Incentive Plan, the "Board" refers to the Compensation Committee as well as to the Board of Directors itself. In addition, the Equity Incentive Plan provides that, in the Board's discretion, directors who grant options to employees covered under Section 162(m) of the Internal Revenue Code ("Section 162(m)") generally will be "outside directors" as defined in Section 162(m). See "How have we responded to the IRS limits on deductibility of compensation?" below for a discussion of the application of Section 162(m). The Equity Incentive Plan provides for the following types of awards: incentive stock options, nonqualified (or "nonstatutory") stock options, stock appreciation rights, restricted stock awards, restricted stock units, and other stock awards. Were awards made under the Equity Incentive Plan for 2005? No. Awards were not made for 2005. Does the Group have an Executive Severance Plan? Yes. Effective December 16, 1998, the Board of Directors adopted an Executive Severance Plan for the benefit of the officers of Group and its subsidiaries. The Board adopted the plan, in the event of a change in control, to provide effective leadership during a transition period. Prior to a change in control, the plan also would facilitate a transaction that is in the best interests of the Group and its stockholders, and provide some measure of security to management in the event their employment is terminated following a change in control. 22 California Water Service Group REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION How have we responded to the IRS limits on deductibility of compensation? The Committee has reviewed the Group's compensation structure in light of Section 162(m) of the Internal Revenue Code, which limits the amount of compensation that the Group may deduct in determining its taxable income for any year to $1,000,000 for any of its five most highly compensated executive officers. In 2005, no executive officer's compensation exceeded the limitation set by Section 162(m). Compensation Committee: Edward D. Harris, Jr., M.D., Committee Chair Bonnie G. Hill David N. Kennedy Richard P. Magnuson Linda R. Meier COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION No member of the Compensation Committee was an officer or employee of the Group or any of its subsidiaries during 2005. None of the executive officers of the Group has served on the Board of Directors or on the Compensation Committee of any other entity, any of whose officers served either on the Board of Directors or on the Compensation Committee of the Group. California Water Service Group 23 AUDIT COMMITTEE REPORT OF THE AUDIT COMMITTEE The Audit Committee oversees the Group's financial reporting process on behalf of the Board of Directors. The Committee's purpose and responsibilities are set forth in the Audit Committee Charter. The current charter is printed in Appendix A of this Proxy Statement. The Committee consists of four members, each of whom meets the New York Stock Exchange standards for independence and the Sarbanes-Oxley Act independence standards for audit committee membership, and has at least one member meeting the requirements of a financial expert. During 2005, the Committee met six times. The Group's management has primary responsibility for preparing the Group's financial statements and the overall reporting process, including the Group's system of internal controls. KPMG LLP, the Group's independent registered public accounting firm, audited the financial statements prepared by the Group and expressed their opinion that the financial statements present fairly the Group's financial position, results of operations and cash flows in conformity with generally accepted accounting principles. KPMG LLP also audited management's assessment that the Group maintained effective internal control over financial reporting as of December 31, 2005, and expressed their opinion that management's assessment is fairly stated, in all material respects, and that the Group maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005. In connection with the December 31, 2005, financial statements, the Audit Committee: (1) reviewed and discussed the audited financial statements with management and the independent registered public accounting firm; (2) discussed with the independent registered public accounting firm the matters required by Statement on Auditing Standards No. 61, "Communication with Audit Committees;" (3) received from KPMG LLP and discussed with the auditor written disclosures required by the Independence Standards Board Standard No. 1, "Independence Discussions with Audit Committees;" the Committee also discussed with KPMG LLP the firm's independence, and considered whether the firm's provision of non-audit services and the fees and costs billed for those services are compatible with KPMG LLP's independence; and (4) met privately with the Group's independent registered public accounting firm and internal auditors, each of whom has unrestricted access to the Audit Committee, without management present, and discussed their evaluations of the Group's internal controls and overall quality of the Group's financial reporting and accounting principles used in preparation of financial statements. The Committee also met privately with the Group's Chairman and the President and Chief Executive Officer, the Chief Financial Officer and the Controller to discuss the same issues. Based upon these reviews and discussions, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Annual Report on Form 10-K to be filed with the Securities and Exchange Commission. AUDIT COMMITTEE George A. Vera, Committee Chair Douglas M. Brown Richard P. Magnuson Linda R. Meier 24 California Water Service Group Relationship with the independent registered public accounting firm The Audit Committee has selected KPMG LLP to serve as the Group's independent registered public accounting firm for the year ending December 31, 2006. The Committee's selection of KPMG LLP as independent registered public accounting firm is submitted for ratification by vote of the stockholders at their Annual Meeting. - ---------------------------- ------------------------- ------------------------- Category of Services Fiscal Year 2004 Fiscal Year 2005 - ---------------------------- ------------------------- ------------------------- Audit Fees (1) $766,000 $645,500 - ---------------------------- ------------------------- ------------------------- Audit-Related Fees (2) 50,000 0 - ---------------------------- ------------------------- ------------------------- Tax Fees (3) 0 0 - ---------------------------- ------------------------- ------------------------- Subtotal $816,000 $645,500 - ---------------------------- ------------------------- ------------------------- All Other Fees (4) $0 $0 - ---------------------------- ------------------------- ------------------------- (1) The audit services included audits of California Water Service Group and California Water Service Company annual financial statements for the year ended December 31, 2004 and 2005, and quarterly reviews of the Group's interim financial statements.
