Our investments in marketable debt securities all have maturities of less than five years. Net pre-tax unrealized gains for marketable debt securities of $157,000 at March 31, 2021 and $229,000 at December 31, 2020 have been recorded as a component of accumulated other comprehensive loss in stockholders’ equity. We have determined that the net pre-tax unrealized losses for marketable debt securities at March 31, 2021 and December 31, 2020 were caused by fluctuations in interest rates and are temporary in nature. We review our marketable debt securities to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the cost basis, credit quality and our ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. No marketable securities were sold in the three months ended March 31, 2021 or the three months ended March 31, 2020. See Note 6 for additional information regarding the fair value of our investments in marketable securities.


Investments in marketable securities classified as cash equivalents of $5.3 million at March 31, 2021 and $1.3 million at December 31, 2020, consist of corporate debt securities and certificates of deposit. There were no unrealized gains or losses associated with any of these securities at March 31, 2021 or December 31, 2020.


Cash and marketable securities held by foreign subsidiaries totaled $1.0 million at March 31, 2021 and $672,000 at December 31, 2020.
