Note 4 – Cash, Cash Equivalents and Marketable Securities

The Company has classified its investments in marketable securities as available-for-sale and as a current asset. Our 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 year ended December 31, 2019, the Company reported an unrealized loss of $0.1 thousand. The Company had an accumulated unrealized loss of $0.1 thousand for the year ended December 31, 2019. The Company had no marketable securities for the year ended December 31, 2018.

We have determined that the unrealized losses are deemed to be temporary as of December 31, 2019. We believe that the unrealized 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. We have the ability and intent to hold these investments until a recovery of fair value, which may be maturity. We do not consider the investment in corporate bonds to be other-than-temporarily impaired at December 31, 2019.
