Gross unrealized losses for investment in fixed maturities for twelve months or more was less than $0.1 million for both September 30, 2021 and December 31, 2020.

The gross unrealized investment losses as of September 30, 2021 and December 31, 2020, were deemed to be temporary, based on, among other things:

● the duration of time and the relative magnitude to which fair values of these investments have been below their amortized cost was not indicative of an other than temporary impairment loss;

● the absence of compelling evidence that would cause the Company to call into question the financial condition or near-term prospects of the issuer of the investment; and

● the Company’s ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery.

The Company may ultimately record a realized loss after having originally concluded that the decline in value was temporary. Risks and uncertainties are inherent in the methodology the Company uses to assess other-than-temporary declines in value. Risks and uncertainties could include, but are not limited to, incorrect assumptions about financial condition, liquidity or future prospects, inadequacy of any underlying collateral, and unfavorable changes in economic conditions or social trends, interest rates or credit ratings.

As of September 30, 2021, one of the investments in fixed maturities was held in unrealized loss position for 12 months or more, and none as of December 31, 2020.
