Debt Instrument, Credit Rating

The Company monitors the credit quality of held-to-maturity debt securities through the use of credit ratings, which are reviewed and updated quarterly. The Company’s non-rated held-to-maturity debt securities are primarily United States government sponsored enterprise debentures carrying minimal to no credit risk. The non-rated corporate bonds primarily consist of Community Reinvestment Act related bonds secured by loan instruments from low to moderate income borrowers. The remaining non-rated held-to-maturity debt securities balance is comprised of local municipal debt from within the Company’s geographic footprint and is monitored through quarterly or annual financial review. This municipal debt is predominately essential service or unlimited general obligation backed debt. The following tables summarize the amortized cost of held-to-maturity debt securities by credit rating at September 30, 2025 and December 31, 2024 (in thousands):
