commitments , guarantees and contingencies commitments : we had unfunded off-balance sheet commitments to extend credit totaling $ 21.30 billion and $ 17.86 billion as of december 31 , 2013 and 2012 , respectively .
the potential losses associated with these commitments equal the gross contractual amounts , and do not consider the value of any collateral .

the potential losses associated with these guarantees equal the gross contractual amounts , and do not consider the value of any collateral .

indemnified securities financing on behalf of our clients , we lend their securities , as agent , to brokers and other institutions .
in most circumstances , we indemnify our clients for the fair market value of those securities against a failure of the borrower to return such securities .
we require the borrowers to maintain collateral in an amount equal to or in excess of 100% ( 100 % ) of the fair market value of the securities borrowed .
securities on loan and the collateral are revalued daily to determine if additional collateral is necessary or if excess collateral is required to be returned to the borrower .
collateral received in connection with our securities lending services is held by us as agent and is not recorded in our consolidated statement of condition .
the cash collateral held by us as agent is invested on behalf of our clients .
in certain cases , the cash collateral is invested in third-party repurchase agreements , for which we indemnify the client against loss of the principal invested .
we require the counterparty to the indemnified repurchase agreement to provide collateral in an amount equal to or in excess of 100% ( 100 % ) of the amount of the repurchase agreement .
in our role as agent , the indemnified repurchase agreements and the related collateral held by us are not recorded in our consolidated statement of condition. .
