Fair Value of Financial Instruments
NOTE E – Fair Value of Financial Instruments

The fair values of our cash and cash equivalents, restricted 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 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 deferred compensation plans totaled approximately $7.1 million at September 30, 2019 and $6.0 million at December 31, 2018 and are included in other assets. The related liabilities of the same amounts are included in other liabilities.
