Securities Sold under Agreements to Repurchase [Abstract] |
Securities Sold under Agreements to Repurchase | 5. Securities Sold under Agreements to Repurchase Included in short-term borrowings are customer securities sold under agreements to repurchase (“repurchase agreements”) that mature daily and are secured by U.S. agency securities totaling $512.0 million and $358.1 million at September 30, 2017 and December 31, 2016, respectively. The Company borrows funds on a secured basis by selling securities under agreements to repurchase, mainly in connection with treasury management services offered to its deposit customers. As the Company maintains effective control over assets sold under agreements to repurchase, the securities continue to be carried on the consolidated statements of financial condition. Because the Company acts as borrower transferring assets to the counterparty, and the agreements mature daily, the Company’s risk is limited.
