Fair Value of Financial Instruments
 
The carrying value of financial instruments including cash and cash equivalents, restricted cash, accounts receivable, accounts payable, and other accrued liabilities approximated their fair value as of September 30, 2011 and December 31, 2010 because of the relatively short maturity of these instruments.  The fair value of the Company’s investment in preferred stock is estimated to be $1,120,000 at September 30, 2011 and $1,390,000 at December 31, 2010.  The fair value of the Company’s various debt obligations, discounted at then currently available interest rates was approximately $30,004,000 and $29,178,000 at September 30, 2011 and December 31, 2010, respectively.
