Unsecured Credit Facility
Unsecured Credit Facility	Note 10 - Unsecured Credit Facility: Effective October 1, 2010, we entered into a $75 million unsecured credit facility with JPMorgan Chase Bank, N.A., as Administrative Agent and U.S. Bank National Association as Syndication Agent. The credit facility has an accordion feature pursuant to which we can increase the amount available to be borrowed by up to an additional $25 million under certain circumstances. The credit facility expires on October 1, 2013. We had no borrowings under the credit facility as of June 30, 2011 or December 31, 2010. The interest rates payable under the credit facility will be based on defined published rates plus an applicable margin. We must pay a commitment fee based on the unused portion of the revolving credit facility. The credit facility agreement contains customary representations and warranties, as well as customary events of default, in certain cases subject to reasonable and customary periods to cure, including but not limited to: failure to make payments when due, breach of covenants, breach of representations and warranties, insolvency proceedings, certain judgments and attachments and any change of control. The credit facility agreement also contains various customary covenants that, in certain instances, restrict our ability to: (i) incur indebtedness; (ii) create liens on assets; (iii) engage in mergers or consolidations; (iv) engage in dispositions of assets; (v) make investments, loans, guarantees or advances; (vi) pay dividends and distributions or repurchase capital stock; (vii) enter into sale and leaseback transactions; (viii) engage in transactions with affiliates; and (ix) change the nature of our business. In addition, the credit facility agreement requires us to maintain the following financial covenants: (a) a maximum leverage ratio, and (b) a minimum fixed charge coverage ratio. All obligations under the credit facility are guaranteed by our material domestic subsidiaries. We incurred approximately $300 thousand in expenses associated with the credit facility during the six-month period ended June 30, 2011.
