Cal Water Announces Results for the 2nd Quarter of 2009

SAN JOSE, CA, Jul 29, 2009 (MARKETWIRE via COMTEX) -- California Water Service Group (NYSE: CWT) today announced net income of $12.1 million, up 20% from $10.1 million in the second quarter of 2008, and earnings per common share (EPS) of $0.58, an increase of 21% over EPS of $0.48 in the same period last year.

Revenues increased by $11.1 million, or 11%, to $116.7 million, with rate increases adding $19.2 million and water usage by new customers adding $3.4 million. These increases were offset by a decrease in water usage by existing customers and other charges totaling $11.1 million. The combined net effect of the water revenue adjustment mechanism (WRAM) and modified cost balancing account (MCBA) was a $0.4 million decrease in revenue. The WRAM is a ratemaking mechanism that decouples water sales from revenues and the MCBA is an account that allows Cal Water to track and recover or refund changes in water production costs.

Total operating expenses for the second quarter of 2009 increased by $9.6 million to $100.7 million. Water production costs increased by $1.4 million due to higher power costs and wholesale water rates. Administrative costs increased $5.6 million, due primarily to increases in pension, health, and legal expenses. Other operations expenses increased $1.6 million to $14.3 million, as a result of increases in costs of pumping and distributing water.

Fewer water system repairs resulted in a $0.6 million decrease in maintenance expense, which was $4.3 million for the quarter. Depreciation expense increased $1.0 million to $10.3 million as a result of increases in capital expenditures. Taxes other than income increased $0.4 million to $3.9 million.

Other income, net of income taxes, increased $1.1 million to $1.5 million. Interest expense increased $0.6 million to $5.3 million due to a new debt offering in April 2009.

For the twelve months ended June 30, 2009, net income was $44.0 million and dilutive earnings per share were $2.11, compared to net income of $32.2 million and dilutive earnings per share of $1.55 for the same period in the prior year. Revenues for the trailing twelve months were $435.1 million, compared to $378.2 million for the same period last year.

"The most important factor in our financial performance continues to be our ability to recover prudently incurred costs in rates, and our second quarter results were positively affected by our approved rates in the 2007 General Rate Case filing," said President and Chief Executive Officer Peter C. Nelson.

"We also believe that the WRAM and MCBA are working effectively to facilitate water conservation and efficiency programs," Nelson said.

Rate-Related Matters

On July 2, 2009, Cal Water filed a General Rate Case with the California Public Utility Commission for all California operations, beginning an 18-month review process. The filing requests an additional $70.6 million in 2011, followed by increases of $24.8 million in 2012 and 2013. The increased revenues are to cover expense increases and capital projects for 2011 through 2013. The Company cannot predict at this time the rate change the Commission will order in 2011.

Interim rate increases, which are typically allowed in the second and third years following a General Rate Case, became effective on July 23, 2009 for 11 California Districts, which will add $9 million to annual revenues.

Acquisitions and New Business

In the second quarter of 2009, Cal Water received final approval from the California Public Utilities Commission on its acquisition of the Skyline County Water District, a 465-connection system adjacent to Cal Water's Bear Gulch District.
