California Water Service Group Announces Results for the 3rd Quarter of 2012

SAN JOSE, CA -- (Marketwire) -- 11/06/12 -- California Water Service Group (NYSE: CWT) today announced net income of $29.8 million and earnings per share of $0.71 for the third quarter of 2012, compared to net income of $20.9 million and earnings per share of $0.50 in the third quarter of 2011. Included in earnings per share was a $0.15 nonrecurring income tax benefit related to 2011 and prior years due to required tax regulation changes.

Operating revenue for the third quarter increased $8.9 million, or 5.2%, to $178.1 million compared to the third quarter of 2011. Sales to new customers added $0.3 million, general rate increases added $4.3 million, offset rate increases to recover increases in purchased water costs added $4.1 million, and increased usage by existing customers and other activities added $0.2 million.

Total operating expenses for the third quarter of 2012 increased $2.6 million, or 1.9%, to $141.8 million. Water production costs increased $4.9 million, or 7.9%, to $66.5 million, primarily due to wholesale water rate increases. Administrative costs increased $2.3 million, or 10.5%, to $23.9 million, due primarily to labor and benefit expenses. Changes in pension costs for regulated California operations do not affect earnings because the Company is allowed by the California Public Utilities Commission (CPUC) to track pension cost changes in a balancing account for future recovery which creates a corresponding change to operating revenues. Other operations expenses increased $0.2 million, or 0.9%, to $17.7 million, due primarily to increases in conservation, water treatment and water quality expenses. Conservation program expenses in California do not affect earnings because they are tracked in a balancing account for future recovery which creates a corresponding change to operating revenues.

Maintenance expense decreased $0.3 million, or 5.9%, to $4.4 million. Depreciation expense increased $1.0 million, or 7.8% to $13.7 million, due to increases in utility plant. Income taxes charged to operating expenses and other income and expenses decreased $3.8 million due to a nonrecurring income tax benefit related to 2011 and prior years for repairs costs previously capitalized for book and income tax purposes. Effective January 1, 2012, the corporate federal income tax repairs and maintenance deduction for qualified tangible property became mandatory for property placed into service during 2012 and prior years. The new tax regulations require the Company to deduct a significant amount of costs previously capitalized for book and tax purposes. The amount of the Company's 2011 and prior years repairs and maintenance deduction was finalized and recorded during the third quarter of 2012.

Other income, net of income taxes, increased $2.4 million to $0.6 million, due primarily to an unrealized mark-to-market gain associated with the change in value of long-term assets held by the Company's non-qualified retirement plans. Interest expense decreased $0.1 million, or 1.5% to $7.2 million due to lower interest rates on short-term borrowings.

"Our third quarter earnings are in line with our expectations, given the impact of the new tax rule and positive mark-to-market adjustment. More important for the long term is our continued success in operating within our budget and obtaining timely recovery of prudently incurred costs in water rates. Our team continues to focus on these key areas," said Peter C. Nelson, Chairman of the Board and CEO.
