RESTRICTED CASH AND INVESTMENTS

Restricted cash and investments consist principally of collateral that has been provided or pledged to insurance carriers for workers' compensation 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 and highly rated investment grade securities, primarily in municipal debt securities, corporate debt securities, asset-backed securities, and U.S. agency debentures. The majority of our collateral obligations are held in a trust at the Bank of New York Mellon ("Trust"). Our investments have not resulted in any other-than-temporary impairments.
