The Company performs quarterly reviews of its fixed maturities in order to determine whether declines in fair value below the amortized cost basis were considered other-than-temporary in accordance with applicable guidance. At September 30, 2020, we determined that unrealized losses on fixed maturities were primarily due to changes in interest rates as well as the impact of foreign exchange rate changes on certain foreign currency denominated fixed maturities since their date of purchase. All fixed maturity securities continue to pay the expected coupon payments under the contractual terms of the securities. Any credit-related impairment related to fixed maturity securities that the Company does not plan to sell and for which the Company is not more likely than not to be required to sell is recognized in net earnings, with the non-credit related impairment recognized in comprehensive earnings.

Based on our analysis, our fixed maturity portfolio is of high credit quality and we believe the amortized cost basis of the securities will ultimately be recovered. The Company continually monitors the credit quality of the fixed maturity investments to assess if it is probable that it will receive contractual or estimated cash flows in the form of principal and interest. For the three and nine months ended September 30, 2020, $962 and $2,468 of OTTI charges were recognized in earnings on two and four fixed maturity securities, respectively. For the three and nine months ended September 30, 2019, the Company recognized $165 in OTTI charges in earnings on one fixed maturity security.
