NOTE 9.     FAIR VALUE

 

At September 30, 2020 and December 31, 2019, our financial instruments included cash, cash equivalents, restricted cash, receivables, marketable equity securities, certain investments, accounts payable, and long-term debt. The carrying value of cash, cash equivalents, restricted cash, receivables, and accounts payable approximates fair value due to the short-term nature of the instruments. The fair value of long-term debt is estimated using quoted prices for similar debt (level 2 in the fair value hierarchy). At September 30, 2020 , the estimated fair value of our long-term debt was $24,246,402 which exceeds the carrying amount of $23,353,002.

 

Marketable equity securities, corporate bonds, and U.S. Treasury securities available for sale are reported at fair value. Substantially all of the fair value is determined using observed prices of publicly traded securities, level 1 in the fair value hierarchy. Fair values for equity investments in private companies are not readily available, but are estimated to approximate fair value.
