U.S. government agency securities - government-sponsored enterprises represent securities issued by Federal National Mortgage Association (“FNMA”) and the SBA. Municipal securities include securities issued by various municipalities located primarily within Wisconsin and are primarily general obligation bonds that are tax-exempt in nature. Residential and commercial mortgage-backed securities - government issued represent securities guaranteed by the Government National Mortgage Association. Residential and commercial mortgage-backed securities - government-sponsored enterprises include securities guaranteed by the Federal Home Loan Mortgage Corporation, FNMA, and the FHLB. Other securities represent certificates of deposit of insured banks and savings institutions with an original maturity greater than three months. There were no sales of available-for-sale securities that occurred during the three months ended March 31, 2021 and one sale of available-for-sale securities that occurred during the three months ended March 31, 2020.

At March 31, 2021 and December 31, 2020, securities with a fair value of $29.7 million and $73.7 million, respectively, were pledged to secure various obligations, including interest rate swap contracts and municipal deposits.

The amortized cost and fair value of securities by contractual maturity at March 31, 2021 are shown below. Actual maturities may differ from contractual maturities because issuers have the right to call or prepay certain obligations with or without call or prepayment penalties.

The tables below show the Corporation’s gross unrealized losses and fair value of available-for-sale investments aggregated by investment category and length of time that individual investments were in a continuous loss position at March 31, 2021 and December 31, 2020. At March 31, 2021, the Corporation held 26 available-for-sale securities that were in an unrealized loss position. Such securities have not experienced credit rating downgrades; however, they have primarily declined in value due to the current interest rate environment. At March 31, 2021, the Corporation held four available-for-sale securities that had been in a continuous unrealized loss position for twelve months or greater.

The Corporation also has not specifically identified available-for-sale securities in a loss position that it intends to sell in the near term and does not believe that it will be required to sell any such securities. The Corporation reviews its securities on a quarterly basis to monitor its exposure to other-than-temporary impairment. Consideration is given to such factors as the length of time and extent to which the security has been in an unrealized loss position, changes in security ratings, and an evaluation of the present value of expected future cash flows, if necessary. Based on the Corporation’s evaluation, it is expected that the Corporation will recover the entire amortized cost basis of each security. Accordingly, no other-than-temporary impairment was recorded in the unaudited Consolidated Statements of Income for the three months ended March 31, 2021 and 2020.

A summary of unrealized loss information for securities available-for-sale, categorized by security type and length of time for which the security has been in a continuous unrealized loss position, follows:

The tables below show the Corporation’s gross unrealized losses and fair value of held-to-maturity investments, aggregated by investment category and length of time that individual investments were in a continuous loss position at March 31, 2021 and December 31, 2020.
