RESTRICTED CASH
5. RESTRICTED CASH
At June 30, 2011 and December 31, 2010, we had $10.0 million and $2.5 million, respectively in a restricted cash account on deposit with our insurance carrier. The restricted cash serves as collateral, in place of an irrevocable stand-by letter of credit, to provide financial assurance that we will fulfill our obligations with respect to cash requirements associated with workers compensation self-insurance. This cash is to remain on deposit with the carrier until all claims have been paid or we provide a letter of credit in lieu of the cash deposit.
