Income from these investments totaled
$61
and
$68
during the
three
months ended
March 31, 2021
and
2020,
respectively, and was included as a portion of interest and investment income on the Company's consolidated statements of operations.
 
Based on the Company's review of its debt securities in an unrealized loss position at
March 31, 2021,
it determined that the losses were primarily the result current economic factors, impacting all global debt and equity markets, that are the result of the global COVID-
19
pandemic. The impact to the Company's investment portfolio is considered to be temporary, rather than a deterioration of overall credit quality. As of
March 31, 2021,
all investments are current on their schedule interest and dividend payments. The Company does
not
intend to sell, and it is
not
more likely than
not
that the Company will be required to sell, these securities prior to recovering their amortized cost. As such, the Company does
not
consider these securities to be other-than-temporarily impaired at
March 31, 2021.
