There were no realized gains or losses on investments for the three and nine months ended September 30, 2021 or 2020. There were two investments and one investment in an unrealized loss position as of September 30, 2021 and December 31, 2020, respectively. None of these investments had been in an unrealized loss position for more than 12 months. The fair value of these securities as of September 30, 2021 and December 31, 2020 was $9.8 million and $6.0 million, respectively, and the aggregate unrealized loss was immaterial. The Company considered the decline in the market value for these securities to be primarily attributable to current economic conditions. As it was not more likely than not that the Company would be required to sell these securities before the recovery of their amortized cost basis, which may be at maturity, the Company did not consider these investments to be other-than-temporarily impaired as of September 30, 2021 and December 31, 2020, respectively.
