Note 4 – Cash, Cash Equivalents, Restricted Cash and Marketable Securities

The Company considers all highly liquid financial instruments with original maturities of three months or less when purchased to be cash and cash equivalents and all investments with maturities of greater than three months from date of purchase are classified as marketable securities. Cash and cash equivalents consisted of cash in bank checking and savings accounts, money market funds and short-term U.S. treasury bonds that mature within three months of settlement date.

Marketable Securities

The Company has classified its investments in marketable securities as available-for-sale and as a current asset. The Company’s investments in marketable securities are carried at fair value, with unrealized gains and losses included as a separate component of stockholders’ equity. Unrealized gains and losses are classified as other comprehensive income (loss) and costs are determined on a specific identification basis. Realized gains and losses from our marketable securities are recorded in other income, net. For the years ended December 31, 2020 and 2019, the Company recorded unrealized gains/(losses) of approximately $237.5 thousand and $0.9 thousand, respectively, and reclassed approximately $8.5 thousand to net loss from operations from the sale of certain securities during 2020.

The Company determined that the unrealized gains and (losses) are deemed to be temporary as of December 31, 2020. Unrealized gains and (losses) generally are the result of increases in the risk premiums required by market participants rather than an adverse change in cash flows for a fundamental weakness in the credit quality of the issuer or underlying assets. The Company has the ability and intent to hold these investments until maturity. The Company does not consider the investment in marketable securities to be other-than-temporarily impaired at December 31, 2020.
