Restricted cash and cash equivalents are restricted for the purchase of revenue earning vehicles and other specified uses under our Fleet Debt facilities, for our Like-Kind Exchange Program, or "LKE Program," and to satisfy certain of our self-insurance regulatory reserve requirements. As of March&nbsp;31, 2011 and December&nbsp;31, 2010, the portion of total restricted cash and cash equivalents that was associated with our Fleet Debt facilities was $110.2&nbsp;million and $115.6&nbsp;million, respectively. The decrease in restricted cash and cash equivalents associated with our fleet debt of $5.4&nbsp;million from December&nbsp;31, 2010 to March&nbsp;31, 2011 was primarily related to payments to reduce fleet debt and the timing of purchases and sales of revenue earning vehicles.</font></p></td></tr></table> Note&nbsp;3&#151;Cash and Cash Equivalents and Restricted Cash and Cash Equivalents We consider all highly liquid debt instruments purchased with an originalfalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringSeparate disclosure of the cash and cash items which are restricted as to withdrawal or usage.
