(a) The accrued interest associated with our available for sale portfolio totaled $244 million and $238 million at March 31, 2021 and December 31, 2020, respectively. These amounts are included in Other assets on the Consolidated Balance Sheet. (b) Amortized cost is presented net of allowance of $105 million and $79 million for securities available for sale at March 31, 2021 and December 31, 2020, respectively. (c) Credit ratings represent a primary credit quality indicator used to monitor and manage credit risk. 85% of our securities held to maturity were rated AAA/AA as of both March 31, 2021 and December 31, 2020. The fair value of investment securities is impacted by interest rates, credit spreads, market volatility and liquidity conditions. Securities available for sale are carried at fair value with net unrealized gains and losses included in Shareholders’ equity as AOCI, unless credit related. Net unrealized gains and losses are determined by taking the difference between the fair value of a security and its amortized cost, net of any allowance. Securities held to maturity are carried at amortized cost less any allowance. Investment securities at March 31, 2021 included $1.8 billion of net unsettled purchases which represent non-cash investing activity, and accordingly, are not reflected on the Consolidated Statement of Cash Flows. The comparable amount for March 31, 2020 was $0.4 billion. We maintain the allowance for investment securities at levels that we believe to be appropriate as of the balance sheet date based on estimation of expected credit losses on our portfolio. As of March 31, 2021, the allowance for investment securities was $108 million and primarily related to non-agency commercial mortgage-backed securities in the available for sale portfolio. The provision for credit losses on investment securities totaled $26 million for the three months ended March 31, 2021. Table 36 presents the gross unrealized losses and fair value of securities available for sale that do not have an associated allowance for investment securities as of March 31, 2021. These securities are segregated between investments that had been in a continuous unrealized loss position for less than twelve months and twelve months or more, based on the point in time that the fair value declined below the amortized cost basis. All securities included in the table have been evaluated to determine if a credit loss exists. As part of that assessment, as of March 31, 2021, we concluded that we do not intend to sell and believe we will not be required to sell these securities prior to recovery of the amortized cost basis.
