Credit Agreements In the normal course of its operations, the Company enters into agreements with financial institutions to obtain unsecured and secured credit facilities. These facilities are used primarily for the issuance of letters of credit, although a portion of these facilities may also be used for liquidity purposes. On May 14, 2010, the Company entered into an agreement to modify an existing credit facility. Under the terms of the agreement, this credit facility was increased from a $100 million unsecured credit facility to a $250 million combined credit facility, with the initial $100 million being unsecured and any utilization above that being secured. This credit facility matures on May 14, 2011, and can be extended automatically to May 14, 2012.On July 16, 2010, the Company terminated its existing $660 million five-year syndicated unsecured credit facility, which had a maturity date of September 30, 2010, and entered into a new $750 million three-year syndicated unsecured credit facility. The new facility has the following terms: (i) a maturity date of July 16, 2013, (ii) a $250 million accordion feature, which enables the Company to potentially increase its available credit from $750 million to $1 billion, and (iii) a minimum consolidated tangible net worth requirement. The Company's ability to increase its available credit to $1 billion is subject to the agreement of the credit facility participants. The Company's breach of any of the covenants would result in an event of default, upon which the Company may be required to repay any outstanding borrowings and replace or cash collateralize letters of credit issued under this facility. The Company was in compliance with all of the covenants as of September 30, 2010. The new facility is predominantly used for the issuance of letters of credit, although the Company and its subsidiaries have access to a revolving line of credit of up to $375 million as part of this facility. At September 30, 2010, there were no borrowings under this revolving line of credit.See Note 21 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2009 for further information related to the credit facilities available to the Company. 10.
