Secured Borrowing Arrangements

Secured Borrowings (Repurchase Agreements) — The Company participates in transactions involving securities sold under repurchase agreements, which are secured borrowings and generally mature one day from the transaction date or involve arrangements with no definite termination date. Securities sold under repurchase agreements are reflected at the amount of cash received in connection with the transactions. The Company may be required to provide additional collateral based on the fair value of the underlying securities, which is monitored on a daily basis.

Securities Lending Activities — The Company’s securities lending activities include lending securities for other broker-dealers, lending institutions and its own clearing and retail operations. These activities involve lending securities to other broker-dealers to cover short sales, to complete transactions in which there has been a failure to deliver securities by the required settlement date and as a conduit for financing activities.

When lending securities, the Company receives cash or similar collateral and generally pays interest (based on the amount of cash deposited) to the other party to the transaction. Securities lending transactions are executed pursuant to written agreements with counterparties that generally require securities loaned to be marked-to-market on a daily basis. The Company receives collateral in the form of cash in an amount generally in excess of the fair value of securities loaned. The Company monitors the fair value of securities loaned on a daily basis, with additional collateral obtained or refunded, as necessary. Collateral adjustments are made on a daily basis through the facilities of various clearinghouses. The Company is a principal in these securities lending transactions and is liable for losses in the event of a failure of any other party to honor its contractual obligation. Management sets credit limits with each counterparty and reviews these limits regularly to monitor the risk level with each counterparty. The Company is subject to credit risk through its securities lending activities if securities prices decline rapidly because the value of the Company’s collateral could fall below the amount of the indebtedness it secures. In rapidly appreciating markets, credit risk increases due to short positions. The Company’s securities lending business subjects the Company to credit risk if a counterparty fails to perform or if collateral securing its obligations is insufficient. In securities transactions, the Company is subject to credit risk during the period between the execution of a trade and the settlement by the customer.
