California Water Service Group Announces First Quarter 2011 Results

SAN JOSE, CA -- (MARKET WIRE) -- 05/04/11 -- California Water Service Group (NYSE: CWT) today announced net income of $2.7 million and earnings per share of $0.13 for the first quarter of 2011, which includes a favorable, one-time tax adjustment of $1.6 million, or $0.08 per share, compared to net income of $2.0 million and earnings per share of $0.10 for the first quarter of 2010.

Revenue for the first quarter increased $7.9 million, or 9%, to $98.1 million compared to the first quarter of 2010. In the first quarter of 2011, the combined effect of the water revenue adjustment mechanism (WRAM) and modified cost balancing account (MCBA) added $6.1 million to revenue. The WRAM is a ratemaking mechanism that decouples water sales from revenues and the MCBA is an account that allows the utility to track and recover or refund changes in water production costs.

Total operating expenses for the first quarter of 2011 increased $5.7 million, or 7%, to $88.2 million. Water production costs increased $1.5 million, or 5%, due primarily to increases in wholesaler water prices and higher pump taxes. Administrative costs increased $3.1 million, or 18%, to $20.5 million, due primarily to increases in employee wages and benefits costs. Other operations expenses increased $1.1 million, or 8%, to $14.6 million, as a result of increases in expenses for conservation, water treatment, and water quality.

Maintenance expense increased 5%, or $0.2 million, to $5.2 million, compared to $5.0 million in the same period last year. Depreciation expense increased $1.8 million, or 17%, to $12.6 million, due to increases in utility plant and updated depreciation rates from the 2009 General Rate Case that became effective on January 1, 2011. Income taxes for the first quarter of 2011 reflected a non-reoccurring, favorable adjustment of $1.6 million as a result of an accounting change in the tax depreciation method used in California which was approved during the quarter by the California Franchise Tax Board. The remaining difference in income taxes of $1.0 million was due to a decline in pre-tax income compared with the prior year.

Other income, net of income taxes, increased by $0.6 million due to a decline in non-regulated expenses associated with potential acquisitions recorded during the first quarter of 2010 compared to the first quarter of 2011. Net Interest expense increased $2.1 million, or 37%, to $7.8 million, due to increased long-term debt interest from the November 2010 debt offering.

According to President and Chief Executive Officer Peter C. Nelson, "We started 2011 with new rates in effect as of January 1st as a result of the 2009 General Rate Case. As anticipated, water revenues are significantly lower in the first quarter; and we expect that greater amounts of rate relief will be concentrated during the summer and fall months."

"In addition, we started 2011 funding an aggressive conservation program," added Nelson. "Helping our customers save money and conserve water is a key goal for us, as outlined in the Commission's updated Water Action Plan. The plan's objectives are to maintain high water quality standards, strengthen water conservation, promote water infrastructure investment, streamline the Commission decision-making, provide for low-income ratepayers, and set rates that balance investment, conservation, and affordability," he said.

All stockholders and interested investors are invited to listen to the 2011 first quarter conference call on May 5, 2011, at 11:00 a.m. (EDT), by dialing 1-866-814-1914 and keying in ID# 1519942.

Nelson, will also be webcast under the investor relations tab at www.calwatergroup.com.
