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 and interest rate derivatives. ​ 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 and/or securities as collateral to secure borrowing capacity. For interest rate derivatives, 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 certain interest rate derivatives, 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 June 30, 2025 and December 31, 2024 were as follows: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
(dollars in thousands) |  | June 30, 2025 |  | December 31, 2024 |
Public deposits | ​ | $ | 1,745,433 | ​ | $ | 1,729,131 | ​
Federal Home Loan Bank | ​ | ​ | 4,858,872 | ​ | ​ | 4,959,298 | ​
Federal Reserve Bank | ​ | ​ | 4,032,254 | ​ | ​ | 3,605,233 | ​
Interest rate derivatives | ​ | ​ | — | ​ | ​ | 385 | ​
Total | ​ | $ | 10,636,559 | ​ | $ | 10,294,047 | ​
​ As the Company did not enter into reverse repurchase agreements or repurchase agreements, no collateral was accepted as of June 30, 2025 and December 31, 2024. In addition, no debt was extinguished by in-substance defeasance.
