These borrowing transactions can range from overnight to six months in maturity. The average maturity was one day at September 30, 2021. Securities sold under agreements to repurchase are used to facilitate the needs of our customers as well as to facilitate our short-term funding needs. Securities sold under repurchase agreements are carried at the amount of cash received in association with the agreement. We continuously monitor the collateral levels and may be required, from time to time, to provide additional collateral based on the fair value of the underlying securities. Securities pledged as collateral under repurchase agreements are maintained with our safekeeping agents. The following table presents detail regarding the securities pledged as collateral under repurchase agreements as of September 30, 2021 and December 31, 2020. All of the repurchase agreements are overnight agreements.
