Within the available for sale debt securities portfolio, the total number of security positions in an unrealized loss position was 720 and 730 at September 30, 2023 and December 31, 2022, respectively.
As of September 30, 2023, the fair value of available for sale debt securities that were pledged to secure public deposits, repurchase agreements, lines of credit, and for other purposes required by law was $803.0 million.
The contractual maturities of available for sale debt securities at September 30, 2023 are set forth in the following table. Maturities may differ from contractual maturities in residential mortgage-backed securities because the mortgages underlying the securities may be prepaid without any penalties. Therefore, residential mortgage-backed securities are not included in the maturity categories in the following summary.

Actual maturities of available for sale debt securities may differ from those presented above since certain obligations provide the issuer the right to call or prepay the obligation prior to scheduled maturity without penalty.
The weighted average remaining expected life for residential mortgage-backed securities available for sale was 7.84 years at September 30, 2023.
Impairment Analysis of Available For Sale Debt Securities
Valley's available for sale debt securities portfolio includes corporate bonds and revenue bonds, among other securities. These types of securities may pose a higher risk of future impairment charges by Valley as a result of the changes in market interest rates, unpredictable nature of the U.S. economy and their potential negative effect on the future performance of the security issuers.
Available for sale debt securities in unrealized loss positions are evaluated for impairment related to credit losses on a quarterly basis. Based on a comparison of the present value of expected cash flows to the amortized cost, Valley recognized a credit related impairment of one corporate bond issued by Signature Bank resulting in a provision for credit losses and full charge-off of the bond totaling $5.0 million during the three months ended March 31, 2023. Valley also evaluated available for sale debt securities that are in an unrealized loss position as of September 30, 2023 included in the table above and has determined that the declines in fair value are mainly attributable to interest rates, credit spreads, market volatility and liquidity conditions, not credit quality or other factors. There was no impairment recognized during the three months ended September 30, 2023 and 2022, and the nine months ended September 30, 2022.
The following table details the activity in the allowance for credit losses for the nine months ended September 30, 2023.

Valley does not intend to sell any of its available for sale debt securities in an unrealized loss position prior to recovery of their amortized cost basis, and it is more likely than not that Valley will not be required to sell any of its securities prior to recovery of their amortized cost basis. None of the available for sale debt securities were past due as of September 30, 2023 and there was no allowance for credit losses for available for sale debt securities at September 30, 2023, December 31, 2022 and September 30, 2022.

Obligations of states and political subdivisions include municipal bonds and revenue bonds issued by various municipal corporations. At September 30, 2023, most of the obligations of states and political subdivisions were rated investment grade and a large portion of the "non-rated" category included tax exempt mortgage securities (TEMS) secured by Ginnie Mae securities. Trust preferred securities consist of non-rated single-issuer securities, issued by bank holding companies. Corporate and other debt securities in the non-rated category mostly consist of high quality foreign issued bonds.
Allowance for Credit Losses for Held to Maturity Debt Securities
Valley has a zero-loss expectation for certain securities within the held to maturity portfolio, and therefore it is not required to estimate an allowance for credit losses related to these securities under the Current Expected Credit Losses (CECL) standard. After an evaluation of qualitative factors, Valley identified the following securities types which it believes qualify for this exclusion: U.S. Treasury securities, U.S. government agency securities, residential mortgage-backed securities issued by Ginnie Mae, Fannie Mae and Freddie Mac, and TEMS collateralized municipal bonds.
The following table details the activity in the allowance for credit losses for the three and nine months ended September 30, 2023 and 2022:
