The Corporation excludes accrued interest from the amortized cost basis of debt securities and reports accrued interest in other assets in the Unaudited Consolidated Balance Sheets. Accrued interest receivable on available for sale debt securities totaled $2.6 million and $2.3 million, respectively, as of June 30, 2022 and December 31, 2021.

As of June 30, 2022 and December 31, 2021, securities with a fair value of $292.9 million and $332.0 million, respectively, were pledged as collateral for FHLB borrowings, potential borrowings with the FRBB, certain public deposits and for other purposes. See Note 7 for additional disclosure on FHLB borrowings.

The schedule of maturities of available for sale debt securities is presented below. Mortgage-backed securities are included based on weighted average maturities, adjusted for anticipated prepayments. All other debt securities are included based on contractual maturities. Actual maturities may differ from amounts presented because certain issuers have the right to call or prepay obligations with or without call or prepayment penalties.

Final maturities of the callable securities range from 2 years to 15 years, with call features ranging from 1 month to 1 year.

Assessment of Available for Sale Debt Securities for Impairment

Management assesses the decline in fair value of investment securities on a regular basis. Unrealized losses on debt securities may occur from current market conditions, increases in interest rates since the time of purchase, a structural change in an investment, volatility of earnings of a specific issuer, or deterioration in credit quality of the issuer. Management evaluates both qualitative and quantitative factors to assess whether an impairment exists.

A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a debt security placed on nonaccrual is reversed against interest income. There were no debt securities on nonaccrual status at June 30, 2022 and 2021 and, therefore there was no accrued interest related to debt securities reversed against interest income for the three and six months ended June 30, 2022 and 2021.

The following tables summarize available for sale debt securities in an unrealized loss position, for which an ACL on securities has not been recorded, segregated by length of time that the securities have been in a continuous unrealized loss position:

Deterioration in credit quality of the underlying issuers of the securities, deterioration in the condition of the financial services industry, worsening of the current economic environment, or declines in real estate values, among other things, may further affect the fair value of these securities and increase the potential that certain unrealized losses be designated as credit losses, and the Corporation may incur write-downs.

Obligations of U.S. Government Agency and U.S. Government-Sponsored Enterprise Securities, including Mortgage-Backed Securities

The gross unrealized losses on U.S. government agency and U.S. government-sponsored debt securities, including mortgage-

backed securities, were primarily attributable to relative changes in interest rates since the time of purchase. The contractual cash flows for these securities are guaranteed by U.S. government agencies and U.S. government-sponsored enterprises. The issuers of these securities continue to make timely principal and interest payments and none of these securities were past due at June 30, 2022. Management believes that the unrealized losses on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality. Management expects to recover the entire amortized cost basis of these securities. Furthermore, the Corporation does not intend to sell these securities and it is likely that the Corporation will not be required to sell these securities before recovery of their cost basis, which may be maturity. Therefore, no allowance for credits losses on securities was recorded at June 30, 2022.

Individual Name Issuer Trust Preferred Debt Securities

Included in debt securities in an unrealized loss position at June 30, 2022 were three trust preferred securities issued by three individual companies in the banking sector. Management reviewed the collectability of these securities taking into consideration such factors as the financial condition of the issuers, reported regulatory capital ratios of the issuers, credit ratings, including ratings in effect as of the reporting period date, as well as credit rating changes between the reporting period date and the filing date of this report, and other information. As of June 30, 2022, there was one individual name issuer trust preferred debt security with an amortized cost of $2.0 million and unrealized losses of $154 thousand that was rated below investment grade by S&P. We noted no downgrades to below investment grade between June 30, 2022 and the filing date of this report. Based on the information available through the filing date of this report, all individual name issuer trust preferred debt securities held in our portfolio continue to accrue interest and make payments as expected with no payment deferrals or defaults on the part of the issuers. Management believes the unrealized losses on these debt securities are primarily attributable to changes in the investment spreads and interest rates and not changes in the credit quality of the issuers of the debt securities. Management expects to recover the entire amortized cost basis of these securities. Furthermore, the Corporation does not intend to sell these securities and it is likely that the Corporation will not be required to sell these securities before recovery of their cost basis, which may be maturity. Therefore, no ACL on securities was recorded at June 30, 2022.

Corporate Bonds

Included in debt securities in an unrealized loss position at June 30, 2022 were four corporate bond holdings issued by three individual companies in the financial services industry. Management reviewed the collectability of these securities taking into consideration such factors as the financial condition of the issuers, reported regulatory capital ratios of the issuers, credit ratings, including ratings in effect as of the reporting period date, as well as credit rating changes between the reporting period date and the filing date of this report, and other information. As of June 30, 2022, there was one corporate bond debt security with an amortized cost of $2.0 million and unrealized losses of $136 thousand that was rated below investment grade by S&P. We noted no downgrades to below investment grade between June 30, 2022 and the filing date of this report. Based on the information available through the filing date of this report, all corporate bond debt securities held in our portfolio continue to accrue interest and make payments as expected with no payment deferrals or defaults on the part of the issuers. Management believes the unrealized losses on these debt securities are primarily attributable to changes in the investment spreads and interest rates and not changes in the credit quality of the issuers of the debt securities. Management expects to recover the entire amortized cost basis of these securities. Furthermore, the Corporation does not intend to sell these securities and it is likely that the Corporation will not be required to sell these securities before recovery of their cost basis, which may be maturity. Therefore, no ACL was recorded at June 30, 2022.
