Federal funds purchased represent unsecured borrowings from other banks, generally on an overnight basis.

Securities sold under agreements to repurchase ("repurchase agreements") are funds borrowed on a secured basis by selling securities under agreements to repurchase, mainly in connection with treasury-management services offered to deposit customers. The customer repurchase agreements mature daily and are secured by agency securities. As the Company maintains effective control over assets sold under agreements to repurchase, the securities continue to be presented in the Consolidated Balance Sheets. Because the Company acts as a borrower transferring assets to the counterparty, and the agreements mature daily, the Company's risk is limited.

The $900 million of Federal Home Loan Bank ("FHLB") borrowings at September 30, 2023 consisted of two fixed rate advances with a maturity date of October 2, 2023. The $1.4 billion of FHLB borrowings at December 31, 2022 consisted of one fixed rate note entered into on December 30, 2022, that matured on January 3, 2023. The Company continues to hold FHLB short-term borrowings at levels that will vary based on liquidity needs.
