Fair Value of Financial Instruments
NOTE G – Fair Value of Financial Instruments

The fair values of our cash and cash equivalents, accounts receivable, accounts payable and customer deposits approximate their carrying values due to their short-term nature. The assets related to our restricted cash and self-directed, non-qualified deferred compensation plans for certain executives and employees are valued using quoted market prices multiplied by the number of shares held, a Level 1 valuation technique. The assets related to our restricted cash totaled approximately $6.8 million at September 30, 2011. The assets related to our deferred compensation plans totaled approximately $1.3 million at September 30, 2011 and $1.7 million at December 31, 2010 and are included in other assets.  The related liability of the same amount is included in other liabilities.
