12. Securities Financing Activities

We enter into repurchase and reverse repurchase agreements and securities borrowed transactions (securities financing agreements) primarily to finance our inventory positions, acquire securities to cover short positions, accommodate customers’ financing needs, and to settle other securities obligations. We account for these securities financing agreements as collateralized financing transactions. Repurchase and reverse repurchase agreements are recorded on the balance sheet at the amounts at which the securities will be subsequently sold or repurchased. Securities borrowed transactions are recorded on the balance sheet at the amounts of cash collateral advanced. While the right of setoff exists for our securities financing agreements, the assets and liabilities are reported on a gross basis. Repurchase agreements and securities borrowed transactions are included in “Accrued income and other assets” and reverse repurchase agreements in “Federal funds purchased and securities sold under repurchase agreements” on the balance sheet.

The following table summarizes our securities financing agreements as of September 30, 2013, December 31, 2012, and September 30, 2012:

(a)	Netting adjustments take into account the impact of master netting agreements that allow us to settle with a single counterparty on a net basis.

(b)	These adjustments take into account the impact of bilateral collateral agreements that allow us to offset the net positions with the related collateral. The application of collateral cannot reduce the net position below zero. Therefore, any excess collateral is not reflected above.

Like other financing transactions, securities financing agreements contain an element of credit risk. To mitigate and manage credit risk exposure, we generally enter into master netting agreements and other collateral arrangements that give us the right, in the event of default, to liquidate collateral held and to offset receivables and payables with the same counterparty. Additionally, we establish and monitor limits on our counterparty credit risk exposure by product type. For the reverse repurchase agreements, we monitor the value of the underlying securities we have received from counterparties and either request additional collateral or return a portion of the collateral based on the value of those securities. We generally hold collateral in the form of highly rated securities issued by the U.S. Treasury and fixed income securities. In addition, we may need to provide collateral to counterparties under our repurchase agreements and securities borrowed transactions. In general, the collateral we pledge and receive can be sold or repledged by the secured parties.
