We primarily use derivatives to manage exposure to market risk, including interest rate risk, credit risk and foreign currency risk, and to assist customers with their risk management objectives. We designate derivatives either as hedging instruments in a qualifying hedge accounting relationship (fair value or cash flow hedge) or as free-standing derivatives. Free-standing derivatives include economic hedges that do not qualify for hedge accounting and derivatives held for customer accommodation or other trading purposes.

       Our asset/liability management approach to interest rate, foreign currency and certain other risks includes the use of derivatives. Such derivatives are typically designated as fair value or cash flow hedges, or economic hedges. This helps minimize significant, unplanned fluctuations in earnings, fair values of assets and liabilities, and cash flows caused by interest rate, foreign currency and other market value volatility. This approach involves modifying the repricing characteristics of certain assets and liabilities so that changes in interest rates, foreign currency and other exposures do not have a significantly adverse effect on the net interest margin, cash flows and earnings. As a result of fluctuations in these exposures, hedged assets and liabilities will gain or lose market value. In a fair value or economic hedge, the effect of this unrealized gain or loss will generally be offset by the gain or loss on the derivatives linked to the hedged assets and liabilities. In a cash flow hedge, where we manage the variability of cash payments due to interest rate fluctuations by the effective use of derivatives linked to hedged assets and liabilities, the unrealized gain or loss on the derivatives or the hedged asset or liability is generally reflected in other comprehensive income and not in earnings.

       We also offer various derivatives, including interest rate, commodity, equity, credit and foreign exchange contracts, to our customers as part of our trading businesses but usually offset our exposure from such contracts by entering into other financial contracts. These derivative transactions are conducted in an effort to help customers manage their market price risks. The customer accommodations and any offsetting derivative contracts are treated as free-standing derivatives. To a much lesser extent, we take positions executed for our own account based on market expectations or to benefit from price differentials between financial instruments and markets. Additionally, free-standing derivatives include embedded derivatives that are required to be accounted for separately from their host contracts.

       The following table presents the total notional or contractual amounts and fair values for our derivatives. Derivative transactions can be measured in terms of the notional amount, but this amount is not recorded on the balance sheet and is not, when viewed in isolation, a meaningful measure of the risk profile of the instruments. The notional amount is generally not exchanged, but is used only as the basis on which interest and other payments are determined. Derivatives designated as qualifying hedge contracts and free-standing derivatives (economic hedges) are recorded on the balance sheet at fair value in other assets or other liabilities. Customer accommodation, trading and other free-standing derivatives are recorded on the balance sheet at fair value in trading assets, other assets or other liabilities.

• Notional amounts presented exclude $2.7 billion at March 31, 2013, and $4.7 billion at December 31, 2012, of basis swaps that are combined with receive fixed-rate/pay floating-rate swaps and designated as one hedging instrument.
• Includes free-standing derivatives (economic hedges) used to hedge the risk of changes in the fair value of residential MSRs, MHFS, loans and other interests held.
• Represents balance sheet netting of derivative asset and liability balances, and related cash collateral. See the next table in this Note for further information.

The following table provides information on the gross fair values of derivative assets and liabilities, the balance sheet netting adjustments and the resulting net fair value amount recorded on our balance sheet, as well as the non-cash collateral associated with such arrangements. We execute substantially all of our derivative transactions under master netting arrangements. We reflect all derivative balances and related cash collateral subject to enforceable master netting arrangements on a net basis within the balance sheet.

       We determine the balance sheet netting adjustments based on the terms specified within each master netting arrangement. We disclose the balance sheet netting amounts within the column titled “Gross amounts offset in consolidated balance sheet”. Balance sheet netting adjustments are determined at the counterparty level for which there may be multiple contract types. For disclosure purposes, we allocate these adjustments to the contract type for each counterparty proportionally based upon the “Gross amounts recognized” by counterparty. As a result, the net amounts disclosed by contract type may not represent the actual exposure upon settlement of the contracts.

       Balance sheet netting does not include non-cash collateral that we pledge. For disclosure purposes, we present these amounts in the column “Gross amounts not offset in consolidated balance sheet (Disclosure-only netting)” within the next table. We determine and allocate the Disclosure-only netting amounts in the same manner as balance sheet netting amounts.

       The “Net amounts” column within the following table represents the aggregate of our net exposure to each counterparty after considering the balance sheet and Disclosure-only netting adjustments. We manage derivative exposure by monitoring the credit risk associated with each counterparty using counterparty specific credit risk limits, the use of master netting arrangements and obtaining collateral. Derivative contracts executed in over the counter markets are typically bilateral contractual arrangements that are not cleared through a central clearing party and are subject to master netting arrangements. The percentage of derivatives executed in such markets, based on gross fair value, is provided within the next table. In addition to the netting amounts included in the table, we also have balance sheet netting related to resale and repurchase agreements that are disclosed within Note 10.

Fair Value Hedges

We use interest rate swaps to convert certain of our fixed-rate long-term debt and CDs to floating rates to hedge our exposure to interest rate risk. We also enter into cross-currency swaps, cross-currency interest rate swaps and forward contracts to hedge our exposure to foreign currency risk and interest rate risk associated with the issuance of non-U.S. dollar denominated long-term debt. In addition, we use interest rate swaps, cross-currency swaps, cross-currency interest rate swaps and forward contracts to hedge against changes in fair value of certain investments in available-for-sale debt securities due to changes in interest rates, foreign currency rates, or both. We also use interest rate swaps to hedge against changes in fair value for certain mortgages held for sale. The entire derivative gain or loss is included in the assessment of hedge effectiveness for all fair value hedge relationships, except for those involving foreign-currency denominated securities available for sale and long-term debt hedged with foreign currency forward derivatives for which the time value component of the derivative gain or loss related to the changes in the difference between the spot and forward price is excluded from the assessment of hedge effectiveness.

       We use statistical regression analysis to assess hedge effectiveness, both at inception of the hedging relationship and on an ongoing basis. The regression analysis involves regressing the periodic change in fair value of the hedging instrument against the periodic changes in fair value of the asset or liability being hedged due to changes in the hedged risk(s). The assessment includes an evaluation of the quantitative measures of the regression results used to validate the conclusion of high effectiveness.

       The following table shows the net gains (losses) recognized in the income statement related to derivatives in fair value hedging relationships.

• Includes $(3) million and $(1) million, respectively, for the quarters ended March 31, 2013 and 2012, of losses on forward derivatives hedging foreign currency securities available for sale and long-term debt, representing the portion of derivative gains (losses) excluded from the assessment of hedge effectiveness.

Cash Flow Hedges

We hedge floating-rate debt against future interest rate increases by using interest rate swaps, caps, floors and futures to limit variability of cash flows due to changes in the benchmark interest rate. We also use interest rate swaps and floors to hedge the variability in interest payments received on certain floating-rate commercial loans, due to changes in the benchmark interest rate. We use forward contracts to hedge our exposure to foreign currency risk associated with certain non-U.S. dollar denominated operating expenses. Gains and losses on derivatives that are reclassified from OCI to interest income, interest expense and noninterest expense in the current period are included in the line item in which the hedged item's effect on earnings is recorded. All parts of gain or loss on these derivatives are included in the assessment of hedge effectiveness. We assess hedge effectiveness using regression analysis, both at inception of the hedging relationship and on an ongoing basis. The regression analysis involves regressing the periodic changes in cash flows of the hedging instrument against the periodic changes in cash flows of the forecasted transaction being hedged due to changes in the hedged risk(s). The assessment includes an evaluation of the quantitative measures of the regression results used to validate the conclusion of high effectiveness.

       Based upon current interest rates, we estimate that $416 million (pre tax) of deferred net gains on derivatives in OCI at March 31, 2013, will be reclassified into interest income and interest expense during the next twelve months. Future changes to interest rates may significantly change actual amounts reclassified to earnings. We are hedging our exposure to the variability of future cash flows for all forecasted transactions for a maximum of 5 years for both hedges of floating-rate debt and floating-rate commercial loans.

       The following table shows the net gains recognized related to derivatives in cash flow hedging relationships. None of the change in value of the derivatives was excluded from the assessment of hedge effectiveness.

• Amounts were recorded in net interest income and noninterest expense.

Free-Standing Derivatives

We use free-standing derivatives (economic hedges) to hedge the risk of changes in the fair value of certain residential MHFS, certain loans held for investment, residential MSRs measured at fair value, derivative loan commitments and other interests held. The resulting gain or loss on these economic hedges is reflected in mortgage banking noninterest income and other noninterest income.

       The derivatives used to hedge MSRs measured at fair value, which include swaps, swaptions, constant maturity mortgages, forwards, Eurodollar and Treasury futures and options contracts, resulted in net derivative losses of $632 million in first quarter 2013 and net derivative gains of $100 million in first quarter 2012, which are included in mortgage banking noninterest income. The aggregate fair value of these derivatives was a net asset of $113 million and $87 million at March 31, 2013 and December 31, 2012, respectively. The change in fair value of these derivatives for each period end is due to changes in the underlying market indices and interest rates as well as the purchase and sale of derivative financial instruments throughout the period as part of our dynamic MSR risk management process.

       Interest rate lock commitments for residential mortgage loans that we intend to sell are considered free-standing derivatives. Our interest rate exposure on these derivative loan commitments, as well as substantially all residential MHFS, is hedged with free-standing derivatives (economic hedges) such as swaps, forwards and options, Eurodollar futures and options, and Treasury futures, forwards and options contracts. The commitments, free-standing derivatives and residential MHFS are carried at fair value with changes in fair value included in mortgage banking noninterest income. For the fair value measurement of interest rate lock commitments we include, at inception and during the life of the loan commitment, the expected net future cash flows related to the associated servicing of the loan. Fair value changes subsequent to inception are based on changes in fair value of the underlying loan resulting from the exercise of the commitment and changes in the probability that the loan will not fund within the terms of the commitment (referred to as a fall-out factor). The value of the underlying loan is affected primarily by changes in interest rates and the passage of time. However, changes in investor demand can also cause changes in the value of the underlying loan value that cannot be hedged. The aggregate fair value of derivative loan commitments in the balance sheet was a net asset of $415 million and $497 million at March 31, 2013 and December 31, 2012, respectively, and is included in the caption “Interest rate contracts” under “Customer accommodation, trading and other free-standing derivatives” in the first table in this Note.

       We also enter into various derivatives primarily to provide derivative products to customers. To a lesser extent, we take positions based on market expectations or to benefit from price differentials between financial instruments and markets. These derivatives are not linked to specific assets and liabilities in the balance sheet or to forecasted transactions in an accounting hedge relationship and, therefore, do not qualify for hedge accounting. We also enter into free-standing derivatives for risk management that do not otherwise qualify for hedge accounting. They are carried at fair value with changes in fair value recorded as other noninterest income.

       Free-standing derivatives also include embedded derivatives that are required to be accounted for separately from their host contract. We periodically issue hybrid long-term notes and CDs where the performance of the hybrid instrument notes is linked to an equity, commodity or currency index, or basket of such indices. These notes contain explicit terms that affect some or all of the cash flows or the value of the note in a manner similar to a derivative instrument and therefore are considered to contain an “embedded” derivative instrument. The indices on which the performance of the hybrid instrument is calculated are not clearly and closely related to the host debt instrument. The “embedded” derivative is separated from the host contract and accounted for as a free-standing derivative. Additionally, we may invest in hybrid instruments that contain embedded derivatives, such as credit derivatives, that are not clearly and closely related to the host contract. In such instances, we either elect fair value option for the hybrid instrument or separate the embedded derivative from the host contract and account for the host contract and derivative separately.

       The following table shows the net gains recognized in the income statement related to derivatives not designated as hedging instruments.

• Predominantly mortgage banking noninterest income including gains (losses) on the derivatives used as economic hedges of MSRs measured at fair value, interest rate lock commitments and mortgages held for sale.
• Predominantly included in other noninterest income.
• Predominantly included in net gains (losses) from equity investments.
• Predominantly mortgage banking noninterest income including gains (losses) on interest rate lock commitments.
• Predominantly included in net gains from trading activities in noninterest income.

Credit Derivatives

We use credit derivatives primarily to assist customers with their risk management objectives. We may also use credit derivatives in structured product transactions or liquidity agreements written to special purpose vehicles. The maximum exposure of sold credit derivatives is managed through posted collateral, purchased credit derivatives and similar products in order to achieve our desired credit risk profile. This credit risk management provides an ability to recover a significant portion of any amounts that would be paid under the sold credit derivatives. We would be required to perform under the noted credit derivatives in the event of default by the referenced obligors. Events of default include events such as bankruptcy, capital restructuring or lack of principal and/or interest payment. In certain cases, other triggers may exist, such as the credit downgrade of the referenced obligors or the inability of the special purpose vehicle for which we have provided liquidity to obtain funding.

The following table provides details of sold and purchased credit derivatives.

       Protection sold represents the estimated maximum exposure to loss that would be incurred under an assumed hypothetical circumstance, where the value of our interests and any associated collateral declines to zero, without any consideration of recovery or offset from any economic hedges. We believe this hypothetical circumstance to be an extremely remote possibility and accordingly, this required disclosure is not an indication of expected loss. The amounts under non-investment grade represent the notional amounts of those credit derivatives on which we have a higher risk of being required to perform under the terms of the credit derivative and are a function of the underlying assets.

We consider the risk of performance to be high if the underlying assets under the credit derivative have an external rating that is below investment grade or an internal credit default grade that is equivalent thereto. We believe the net protection sold, which is representative of the net notional amount of protection sold and purchased with identical underlyings, in combination with other protection purchased, is more representative of our exposure to loss than either non-investment grade or protection sold. Other protection purchased represents additional protection, which may offset the exposure to loss for protection sold, that was not purchased with an identical underlying of the protection sold.

Credit-Risk Contingent Features

Certain of our derivative contracts contain provisions whereby if the credit rating of our debt were to be downgraded by certain major credit rating agencies, the counterparty could demand additional collateral or require termination or replacement of derivative instruments in a net liability position. The aggregate fair value of all derivative instruments with such credit-risk-related contingent features that are in a net liability position was $15.1 billion at March 31, 2013, and $16.2 billion at December 31, 2012, respectively, for which we posted $12.8 billion and$14.3 billion, respectively, in collateral in the normal course of business. If the credit rating of our debt had been downgraded below investment grade, which is the credit-risk-related contingent feature that if triggered requires the maximum amount of collateral to be posted, on March 31, 2013, or December 31, 2012, we would have been required to post additional collateral of $2.2 billion or $1.9 billion, respectively, or potentially settle the contract in an amount equal to its fair value.

Counterparty Credit Risk

By using derivatives, we are exposed to counterparty credit risk if counterparties to the derivative contracts do not perform as expected. If a counterparty fails to perform, our counterparty credit risk is equal to the amount reported as a derivative asset on our balance sheet. The amounts reported as a derivative asset are derivative contracts in a gain position, and to the extent subject to legally enforceable master netting arrangements, net of derivatives in a loss position with the same counterparty and cash collateral received. We minimize counterparty credit risk through credit approvals, limits, monitoring procedures, executing master netting arrangements and obtaining collateral, where appropriate. To the extent the master netting arrangements and other criteria meet the applicable requirements, including determining the legal enforceability of the arrangement, it is our policy to present derivatives balances and related cash collateral amounts net in the balance sheet. Counterparty credit risk related to derivatives is considered in determining fair value and our assessment of hedge effectiveness. Credit valuation adjustments (“CVA”) are taken to reflect the counterparty credit risk of each counterparty in the valuation of derivatives. CVA adjustments are necessary when the market price (or parameter) is not indicative of the credit quality of the counterparty.
