Impairment Assessment

We adopted ASU 2016-13 in the first quarter of 2020, which made certain amendments to the model used to assess available-for-sale debt securities for impairment. Such guidance provides that an available-for-sale debt security is impaired if the fair value of the security is less than its amortized cost basis. A determination is made whether the decline in fair value below the amortized cost basis has resulted from a credit loss or other factors, such as market liquidity or changes in interest rates. Impairment related to credit losses is recognized in net earnings, whereas impairment related to other factors is recognized as a component of accumulated other comprehensive loss, net. We did not recognize any impairment on our available-for-sale debt securities through net earnings in 2020.
