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 $3.1 billion of Federal Home Loan Bank ("FHLB") borrowings at March 31, 2023 consisted of five fixed rate advances with maturity dates in April and May 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. Subsequent to quarter end, in early May 2023, the Company repaid $1.45 billion of FHLB borrowings at maturity using available excess liquidity, and continues to carry FHLB borrowings that will vary based on cash needs.
