Upon adoption of ASU 2016-13 on January 1, 2020, the Bancorp evaluates available-for-sale debt and other securities in an unrealized loss position to determine whether all or a portion of the unrealized loss on such securities is a credit loss. If credit losses are identified, they are generally recognized as an allowance for credit losses (a contra account to the amortized cost basis of the securities) with the periodic change in the allowance recognized in earnings. Prior to January 1, 2020, investment securities were evaluated for OTTI with any identified OTTI recognized as a charge to income and a direct reduction of the amortized cost basis of the securities.

At June 30, 2020, the Bancorp completed its evaluation of the available-for-sale debt and other securities in an unrealized loss position and did not recognize an allowance for credit losses. The Bancorp did not recognize provision expense for the three and six months ended June 30, 2020 related to available-for-sale debt and other securities in an unrealized loss position.

At June 30, 2020 and December 31, 2019, investment securities with a fair value of $10.8 billion and $8.1 billion, respectively, were pledged to secure borrowings, public deposits, trust funds, derivative contracts and for other purposes as required or permitted by law.
