Commitments and Guarantees

For additional information regarding our commitments and guarantees, refer to note 10 on pages 159 to 160 of the 2014 Form 10-K.

Commitments:

We had unfunded off-balance sheet commitments to extend credit totaling $23.88 billion and $24.43 billion as of March 31, 2015 and December 31, 2014, respectively. The potential losses associated with these commitments equal the gross contractual amounts, and do not consider the value of any collateral. As of March 31, 2015, approximately 78% of our unfunded commitments to extend credit expire within one year. Since many of these commitments are expected to expire or renew without being drawn upon, the gross contractual amounts do not necessarily represent our future cash requirements.

Guarantees:

Off-balance sheet guarantees comprise indemnified securities financing, stable value protection, unfunded commitments to purchase assets, and standby letters of credit. The following table, which presents the aggregate gross contractual amounts of our off-balance sheet guarantees as of the dates indicated, does not consider the value of any collateral, which may mitigate any potential loss. Amounts presented do not reflect participations to independent third parties.



(In millions)	March 31, 2015		December 31, 2014
Indemnified securities financing	$	348,960	$	349,766
Stable value protection	23,425		23,409
Asset purchase agreements	4,212		4,107
Standby letters of credit	4,782		4,720

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.

The following table summarizes the aggregate fair values of indemnified securities financing and related collateral, as well as collateral invested in indemnified repurchase agreements, as of the dates indicated:



(In millions)	March 31, 2015		December 31, 2014
Fair value of indemnified securities financing	$	348,960	$	349,766
Fair value of cash and securities held by us, as agent, as collateral for indemnified securities financing	364,212		364,411
Fair value of collateral for indemnified securities financing invested in indemnified repurchase agreements	78,163		85,309
Fair value of cash and securities held by us or our agents as collateral for investments in indemnified repurchase agreements	83,256		90,819

In certain cases, we participate in securities finance transactions as a principal. As a principal, we borrow securities from the lending client and then lend such securities to the subsequent borrower, either a State Street client or a broker/dealer. Collateral provided and received in connection with such transactions is recorded in other assets and accrued expenses and other liabilities, respectively, in our consolidated statement of condition. As of March 31, 2015 and December 31, 2014, we had approximately $19.85 billion and $15.94 billion, respectively, of collateral provided and approximately $6.96 billion and $6.48 billion, respectively, of collateral received from clients in connection with our participation in principal securities finance transactions.

Stable Value Protection

In the normal course of our business, we offer products that provide book-value protection, primarily to plan participants in stable value funds managed by non-affiliated investment managers of post-retirement defined contribution benefit plans, particularly 401(k) plans. The book-value protection is provided on portfolios of intermediate investment grade fixed-income securities, and is intended to provide safety and stable growth of principal invested. The protection is intended to cover any shortfall in the event that a significant number of plan participants withdraw funds when book value exceeds market value and the liquidation of the assets is not sufficient to redeem the participants. The investment parameters of the underlying portfolios, combined with structural protections, are designed to provide cushion and guard against payments even under extreme stress scenarios.

These contingencies are individually accounted for as derivative financial instruments. The notional amounts of the stable value contracts are presented as “derivatives not designated as hedging instruments” in the table of aggregate notional amounts of derivative financial instruments provided in note 12. We have not made a payment under these contingencies that we consider material to our consolidated financial condition, and management believes that the probability of payment under these contingencies in the future, that we would consider material to our consolidated financial condition, is remote.
