Cash and Cash Equivalents as of December 31, 2008 includes approximately $44.8 million of cash posted to Merrill Lynch & Co. as collateral related to certain total return structure interest rate swap arrangements. No collateral was posted as of December 31, 2009 or December 31, 2010. Assets Whose Use is Limited or Restricted includes the following funds for fiscal years 2008, 2009 and 2010, respectively: $27.2, $34.6 and $43.3 million of restricted funds held in the Aurora Foundation; $56.0, $75.0 and $94.0 million of self insured and other funds held by trustees; and $5.7, $21.3 and $36.6 million of debt service reserve funds. Cash Expenses per Day represent total operating expenses of the Aurora System, less the following non-cash expenses: depreciation and amortization, provision for bad debts, pension expense and the gross up of internally funded health and dental expenses. Days cash on hand were uncharacteristically low as of December 31, 2008 due to the fact that the Aurora System was not able to successfully execute, prior to fiscal year end 2008, several planned sale and leaseback transactions of properties acquired with cash in 2008 in connection with the Advanced Healthcare acquisition. Although Aurora had executed signed purchase and sale agreements, given the state of the credit markets at that time, the purchasers were ultimately not able to obtain the necessary financing to close the transaction. As such, liquidity as of December 31, 2008 was suppressed by approximately 10 days. The planned sale and leaseback transactions were fully executed in fiscal year 2009.
