Investment in Debt Securities-Available for Sale | Note 6. Investment in Debt Securities-Available for Sale Investments in debt securities available for sale with a fair value of $20,775,440 and $21,254,485 as of March 31, 2023 and December 31, 2022, respectively, which consisted of U.S. Treasury securities and corporate debt securities. These investments are valued at estimated fair value, with unrealized gains and losses reported as a separate component of stockholders’ equity in accumulated other comprehensive loss. Investments in debt securities available for sale are evaluated periodically to determine whether a decline in their value is other than temporary. The term “other than temporary” is not intended to indicate a permanent decline in value. Rather, it means that the prospects for near term recovery of value are not necessarily favorable, or that there is a lack of evidence to support fair values equal to, or greater than, the carrying value of the security. Management reviews criteria such as the magnitude and duration of the decline, as well as the reasons for the decline, to predict whether the loss in value is other than temporary. Once a decline in value is determined to be other than temporary, the value of the security is reduced and a corresponding charge to earnings is recognized. A summary of the cost, fair value and maturities of the Company’s short-term investments is as follows: Schedule of Cost, Fair Value and Maturities of Short Term Investments
