3. Marketable Securities
The Company held no marketable securities as of December 31, 2019. Marketable securities at December 31, 2020 consisted of the following:
Corporate debt includes obligations issued by investment-grade corporations, and may include issues that have been guaranteed by governments and government agencies. At December 31, 2020, the Company held only investments that have maturities of less than one year
At December 31, 2020, the Company held 15 debt securities that individually and in total were in an immaterial unrealized loss position for less than one year. The aggregate fair value of debt securities in an unrealized loss position at December 31, 2020 was $18,115,831. The Company evaluated its securities for other-than-temporary impairment and considered the decline in market value for the securities to be primarily attributable to current economic and market conditions. It was not more likely than not that the Company would have been required to sell the securities prior to the recovery of the amortized cost basis. Based on this analysis, these marketable securities were not considered to be other-than-temporarily impaired as of December 31, 2020.
No definition available.
