California Water Service Group Announces First Quarter 2010 Results

SAN JOSE, CA, Apr 28, 2010 (MARKETWIRE via COMTEX) --California Water Service Group (NYSE: CWT) today announced net income of $2.0 million and earnings per share of $0.10 for the first quarter of 2010, compared to net income of $2.4 million and earnings per share of $0.12 for the first quarter of 2009.

Revenue for the first quarter increased $3.7 million, or 4%, to $90.3 million. Rate increases added $4.3 million and sales to new customers added $0.6 million, while decreased usage by existing customers and other charges reduced revenue by $1.2 million.

Total operating expenses for the first quarter of 2010 increased $2.2 million, or 3%, to $82.5 million. Water production costs increased $1.6 million, or 6%, due primarily to increases in wholesaler water prices and higher power costs. Administrative costs decreased $1.4 million, or 8%, to $17.4 million due to lower legal expense and other administrative costs compared with the prior year. Other operations expenses increased $1.1 million, or 9%, to $13.6 million, as a result of increases in expenses for water treatment, water quality, and costs associated with water distribution systems.

Maintenance expense increased 7%, or $0.3 million, to $4.9 million, compared to $4.6 million in the same period last year. Depreciation expense increased $0.6 million, or 6%, to $10.8 million, due to increases in utility plant. Taxes other than income decreased $ 0.2 million, or 5%, to $3.9 million.

Other income, net of income taxes, decreased $0.6 million to a net loss of $0.1 million. The largest single component of the change was due to business development expenses in the regulated utility business. Interest expense increased $1.3 million, or 30%, to $5.7 million, due to the debt issuance in April 2009.

According to President and Chief Executive Officer Peter C. Nelson, 1st quarter 2010 results were in line with management's expectations.

"We are in the third year of a three-year rate case cycle in California, which as planned, resulted in lower rate relief for the first quarter of 2010. We will continue to work diligently to control costs while providing excellent service, both of which will benefit stockholders and rate payers in 2010 and beyond," Nelson said.
