Pledged assets At March 31, 2013, assets were pledged to collateralize repurchase and other securities financing agreements, maintain potential borrowing capacity with central banks and for other purposes, including to secure borrowings and public deposits. Certain of these pledged assets may be sold or repledged by the secured parties and are identified as financial instruments owned (pledged to various parties) on the Consolidated Balance Sheets. In addition, at March 31, 2013, and December 31, 2012, the Firm had pledged $299.0 billion and $291.7 billion, respectively, of financial instruments it owns that may not be sold or repledged by the secured parties. Total assets pledged do not include assets of consolidated VIEs; these assets are used to settle the liabilities of those entities. See Note 15 on pages 151–158 of this Form 10-Q, and Note 16 on pages 280–291 of JPMorgan Chase’s 2012 Annual Report, for additional information on assets and liabilities of consolidated VIEs. Collateral At March 31, 2013, and December 31, 2012, the Firm had accepted assets as collateral that it could sell or repledge, deliver or otherwise use with a fair value of approximately $695.9 billion and $757.1 billion, respectively. This collateral was generally obtained under resale agreements, securities borrowing agreements, customer margin loans and derivative agreements. Of the collateral received, approximately $552.8 billion and $545.0 billion, respectively, were sold or repledged, generally as collateral under repurchase agreements, securities lending agreements or to cover short sales and to collateralize deposits and derivative agreements. The total amount of collateral received and collateral sold or repledged at December 31, 2012, has been revised. This revision had no impact on the Firm’s Consolidated Balance Sheets or its results of operations.
