California Water Service Group Announces Results for 3rd Quarter 2009

SAN JOSE, CA, Oct 28, 2009 (MARKETWIRE via COMTEX) -- California Water Service Group (NYSE: CWT) today announced net income of $19.6 million and earnings per share of $0.94 for the third quarter of 2009, compared to net income of $22.2 million and earnings per share of $1.06 in the third quarter of 2008.

Revenues increased by $7.5 million, or 6%, to $139.2 million, with rate increases adding $12.5 million and water usage by new customers adding $3.3 million. A decrease in water usage by existing customers and other charges reduced revenue by $8.3 million.

Total operating expenses for the third quarter of 2009 increased by $10.1 million, or 10%, to $115.1 million. Water production costs increased by $2.4 million, or 5%, due to higher power costs and wholesale water rates. Administrative costs increased $4.1 million, or 27%, due to increased pension & benefits costs, and increased legal costs. Other operations expenses increased by $1.7 million to $14.6 million as a result of higher costs for pumping and distributing water.

Maintenance expense increased by 15% to $4.4 million as a result of additional water main repairs. Depreciation expense increased by 11% to $10.3 million as a result of increases in capital expenditures. Taxes other than income increased $0.4 million to $4.4 million, primarily due to property tax increases.

Other income, net of income taxes, added $1.0 million of net income for the quarter, while interest expense increased by 33% to $5.5 million due to the new debt offering in April 2009.

For the twelve months ended September 30, 2009, net income was $41.4 million and diluted earnings per share were $1.99, compared to net income of $40.5 million and diluted earnings per share of $1.94 for the same period last year. Revenues for the trailing twelve months were $443 million, compared to $396 million for the same period in the prior year.

"During the quarter, the Company filed its 2009 General Rate Case for all 24 California districts and corporate costs," said President and Chief Executive Officer Peter C. Nelson. "This is significant because we are now filing for rate relief in California for all regulated districts and corporate costs at the same time, which will allow for more timely rate relief of prudently incurred costs," said Nelson.

"While we cannot predict the outcome of this filing, the rate case was filed on time and is currently proceeding on schedule," Nelson said.
