Fair Value Measurements

NOTE 3 – Fair Value Measurements


Marketable debt securities, all of which were classified as available-for-sale, consist of the following:


   March 31, 2021 
   Amortized Cost   Unrealized Gains   Unrealized Losses   Estimated Fair Value 
Corporate Bonds - presented in marketable debt securities, current  $26,165   $           -   $        (21)  $26,144 
Corporate Bonds - presented in marketable debt securities, non-current   70,967    -    (143)   70,824 
Total  $97,132   $-   $(164)  $96,968 

The Company does not consider any portion of the unrealized losses at March 31, 2021 to be credit losses. The Company has recorded the securities at fair value in its unaudited condensed consolidated balance sheet and unrealized gains and losses are reported as a component of accumulated other comprehensive income (loss). The amount of realized gains and losses reclassified into earnings are based on the specific identification of the securities sold or securities that reached maturity date. There were no sales or maturities of securities in the periods presented.


The Company measures certain financial assets and liabilities at fair value. Fair value is determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as determined by either the principal market or the most advantageous market.


Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy, as follows:


Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

The following tables present the Company’s financial assets measured and recorded at fair value on a recurring basis using the above input categories as of March 31, 2021:
