Repurchase Agreement Borrowings

Securities sold under agreements to repurchase ("repurchase agreements") with customers represent funds deposited by customers, generally on an overnight basis, that are collateralized by investment securities owned by Park. Repurchase agreements with customers are included in short-term borrowings on the consolidated condensed balance sheets. Park's repurchase agreements with a third-party financial institution are classified as long-term debt on the consolidated condensed balance sheets.

All repurchase agreements are subject to terms and conditions of repurchase/security agreements between Park and the client and are accounted for as secured borrowings. Park's repurchase agreements reflected in short-term borrowings consisted of customer accounts and securities which are pledged on an individual security basis.
