NOTE 3:	RESTRICTED CASH AND INVESTMENTS

Restricted cash and investments consist primarily of collateral that has been provided or pledged to insurance carriers and state workers' compensation programs. Our insurance carriers and certain state workers' compensation programs require us to collateralize a portion of our workers' compensation obligation. The collateral typically takes the form of cash and cash equivalents, highly rated investment grade debt securities, and cash-backed instruments.

Prior to March 11, 2011, Chartis held the majority of the restricted cash collateralizing our self-insured workers' compensation policies. As of March 11, 2011, we entered into an agreement between Chartis and the Bank of New York Mellon creating a trust at the Bank of New York Mellon which holds the majority of our collateral obligations. During the first quarter of 2011, we transferred $89.1 million to the Trust. The majority of funds in the Trust have been invested in highly rated investment grade U.S. Treasury Securities, U.S. Agency Debentures, U.S. Agency Mortgages, Corporate Securities, and Municipal Securities.
