Transfers of Financial Assets |
Transfers of Financial Assets | 6. Transfers of Financial Assets ​ The Company’s transfers of financial assets with continuing interest may include pledges of collateral to secure public deposits and repurchase agreements, FHLB and FRB borrowing capacity, automated clearing house (“ACH”) transactions and interest rate swaps. ​ For public deposits and repurchase agreements, the Company enters into bilateral agreements with the entity to pledge investment securities as collateral in the event of default. The right of setoff for a repurchase agreement resembles a secured borrowing, whereby the collateral pledged by the Company would be used to settle the fair value of the repurchase agreement should the Company be in default. The counterparty has the right to sell or repledge the investment securities. The Company is required by the counterparty to maintain adequate collateral levels. In the event the collateral fair value falls below stipulated levels, the Company will pledge additional investment securities. For transfers of assets with the FHLB and the FRB, the Company enters into bilateral agreements to pledge loans as collateral to secure borrowing capacity. For ACH transactions, the Company enters into bilateral agreements to collateralize possible daylight overdrafts. For interest rate swaps, the Company enters into bilateral agreements to pledge collateral when either party is in a negative fair value position to mitigate counterparty credit risk. Counterparties to ACH transactions, certain interest rate swaps, the FHLB and the FRB do not have the right to sell or repledge the collateral. ​ The carrying amounts of the assets pledged as collateral to secure public deposits, borrowing arrangements and other transactions as of September 30, 2022 and December 31, 2021 were as follows: ​
​ | ​ | ​ | ​ | ​ | ​ | ​

​ As of September 30, 2022 and December 31, 2021, the borrowing capacity with the FHLB was $1.5 billion and $1.8 billion, respectively. The FHLB fixed-rate advances and remaining borrowing capacity were secured by residential real estate loan collateral as of September 30, 2022 and December 31, 2021. As of September 30, 2022 and December 31, 2021, the Company had an undrawn line of credit of $1.2 billion and $1.1 billion, respectively, from the FRB. The borrowing capacity with the FRB was secured by consumer, commercial and industrial, commercial real estate and residential real estate loans as of September 30, 2022 and December 31, 2021. ​ As the Company did not enter into reverse repurchase agreements or repurchase agreements, no collateral was accepted or pledged as of September 30, 2022 and December 31, 2021. In addition, no debt was extinguished by in-substance defeasance.
