Item 1.01. Entry into a Material Definitive Agreement.
On October 27, 2009 (the "Effective Date"), California Water Service Group, a Delaware corporation (the "Registrant"), and California Water Service Company, a California corporation and a wholly-owned subsidiary of the Registrant ("Cal Water"), entered into the Syndicated Credit Agreements (as defined below), which provide for unsecured revolving credit facilities in an aggregate amount of $300 million. The Syndicated Credit Facilities expand and replace the Registrant and its subsidiaries' Existing Credit Facilities (as defined below). Holdco Credit Agreement
On the Effective Date, the Registrant, and certain of its subsidiaries which may be designated borrowers from time to time, entered into a credit agreement (the "Holdco Credit Agreement") provided by a syndicate of banks and other financial institutions led by Bank of America, N.A., as administrative agent, swing ling lender and letter of credit issuer, Banc of America Securities LLC, as sole lead arranger and sole book manager, CoBank, ACB and Bank of China, Los Angeles Branch, as co-syndication agents, and Compass Bank and U.S. Bank, National Association as co-documentation agents.
Also on the Effective Date, the Registrant terminated its existing facility with Bank of America, N.A. that was due to expire on April 16, 2010 (the "Holdco Existing Facility"). There were no borrowings outstanding under the Holdco Existing Facility.
The Holdco Credit Agreement provides for a $50 million unsecured revolving credit facility, which will be used for working capital purposes, including the short-term financing of capital projects, or general corporate purposes. The Holdco Credit Agreement expires, and all obligations thereunder shall be due and payable, on October 27, 2012, unless earlier accelerated upon the occurrence of an event of default. At the Registrant's option, borrowings under the Holdco Credit Agreement will bear interest annually at a rate equal to (i) the Eurodollar rate or (ii) a base rate, in each case plus an applicable margin dependent on the Registrant and its subsidiaries' consolidated total capitalization ratio.
The Holdco Credit Agreement contains affirmative and negative covenants and events of default customary for credit facilities of this type, including, among other things, limitations and prohibitions relating to additional indebtedness, liens, mergers, and asset sales by the Registrant and its subsidiaries. The Holdco Credit Agreement also contains financial covenants governing the Registrant and its subsidiaries' consolidated total capitalization ratio and interest coverage ratio.
There were no initial borrowings under the Holdco Credit Agreement. Opco Credit Agreement

There were outstanding borrowings under the Opco Existing Facility in the amount of $12 million, which Cal Water repaid in full on the Effective Date.
The Opco Credit Agreement provides for a $250 million unsecured revolving credit facility, which will be used for working capital purposes, including the short-term financing of capital projects.

At Cal Water's option, borrowings under the Opco Credit Agreement will bear interest annually at a rate equal to (i) the Eurodollar rate or (ii) a base rate, in each case plus an applicable margin dependent on the Registrant and its subsidiaries' consolidated total capitalization ratio.
The Opco Credit Agreement contains affirmative and negative covenants and events of default customary for credit facilities of this type, including, among other things, limitations and prohibitions relating to additional indebtedness, liens, mergers, and asset sales. The Opco Credit Agreement also contains financial covenants governing the Registrant and its subsidiaries' consolidated total capitalization ratio and interest coverage ratio.
