Other borrowings may include federal funds purchased, repurchase agreements and borrowings from the FRDW. Southside Bank has three unsecured lines of credit for the purchase of overnight federal funds at prevailing rates with Frost Bank, TIB – The Independent Bankers Bank and Comerica Bank for $40.0 million, $15.0 million and $7.5 million, respectively. There were no federal funds purchased at June 30, 2022 or December 31, 2021.  To provide more liquidity in response to the economic impact of the COVID-19 pandemic, the Federal Reserve took steps to encourage broader use of the discount window. At June 30, 2022, the amount of additional funding the Bank could obtain from the FRDW, collateralized by securities, was approximately $391.1 million. There were $29.0 million in borrowings from the FRDW at June 30, 2022. There were no borrowings from the FRDW at December 31, 2021. Southside Bank has a $5.0 million line of credit with Frost Bank to be used to issue letters of credit, and at June 30, 2022, the line had one outstanding letter of credit for $155,000. Southside Bank currently has no outstanding letters of credit from FHLB held as collateral for its public fund deposits.
Southside Bank enters into sales of securities under repurchase agreements. These repurchase agreements totaled $29.5 million at June 30, 2022 and $23.2 million at December 31, 2021, and had maturities of less than one year.  Repurchase agreements are secured by investment and MBS securities and are stated at the amount of cash received in connection with the transaction.
FHLB borrowings represent borrowings with fixed interest rates ranging from 1.72% to 4.799% and with remaining maturities of 22 days to 6.0 years at June 30, 2022.  FHLB borrowings may be collateralized by FHLB stock, nonspecified loans and/or securities. At June 30, 2022, the amount of additional funding Southside Bank could obtain from FHLB, collateralized by securities, FHLB stock and nonspecified loans and securities, was approximately $1.73 billion, net of FHLB stock purchases required.
