NOTE 14 – Fair Value Measurements

Under applicable accounting guidance, fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Corporation determines the fair values of its financial instruments based on the fair value hierarchy established under applicable accounting guidance which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs used to measure fair value. The Corporation conducts a review of its fair value hierarchy classifications on a quarterly basis. Transfers into or out of fair value hierarchy classifications are made if the significant inputs used in the financial models measuring the fair values of the assets and liabilities became unobservable or observable, respectively, in the current marketplace. These transfers are considered to be effective as of the beginning of the quarter in which they occur. For more information regarding the fair value hierarchy and how the Corporation measures fair value, see Note 1 – Summary of Significant Accounting Principles and Note 20 – Fair Value Measurements to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K. The Corporation accounts for certain financial instruments under the fair value option. For additional information, see Note 15 – Fair Value Option.

Valuation Processes and Techniques

The Corporation has various processes and controls in place to ensure that fair value is reasonably estimated. A model validation policy governs the use and control of valuation models used to estimate fair value. This policy requires review and approval of models by personnel who are independent of the front office, and periodic reassessments of models to ensure that they are continuing to perform as designed. In addition, detailed reviews of trading gains and losses are conducted on a daily basis by personnel who are independent of the front office. A price verification group, which is also independent of the front office, utilizes available market information including executed trades, market prices and market-observable valuation model inputs to ensure that fair values are reasonably estimated. The Corporation performs due diligence procedures over third-party pricing service providers in order to support their use in the valuation process. Where market information is not available to support internal valuations, independent reviews of the valuations are performed and any material exposures are escalated through a management review process.

While the Corporation believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

During the nine months ended September 30, 2015, there were no changes to the valuation techniques that had, or are expected to have, a material impact on the Corporation's consolidated financial position or results of operations.

Level 1, 2 and 3 Valuation Techniques

Financial instruments are considered Level 1 when the valuation is based on quoted prices in active markets for identical assets or liabilities. Level 2 financial instruments are valued using quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or models using inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Financial instruments are considered Level 3 when their values are determined using pricing models, discounted cash flow methodologies or similar techniques, and at least one significant model assumption or input is unobservable and when determination of the fair value requires significant management judgment or estimation.
Recurring Fair Value

Assets and liabilities carried at fair value on a recurring basis at September 30, 2015 and December 31, 2014, including financial instruments which the Corporation accounts for under the fair value option, are summarized in the following tables.

During 2014, the Corporation reclassified certain assets and liabilities within its fair value hierarchy based on a review of its inputs used to measure fair value. Accordingly, approximately $4.1 billion of assets related to U.S. government and agency securities, non-U.S. government securities and equity derivatives, and $570 million of liabilities related to equity derivatives were transferred from Level 1 to Level 2.
The following tables present a reconciliation of all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the three and nine months ended September 30, 2015 and 2014, including net realized and unrealized gains (losses) included in earnings and accumulated OCI.

Includes unrealized gains (losses) on AFS debt securities and foreign currency translation adjustments.
(3) 
Net derivatives include derivative assets of $6.0 billion and derivative liabilities of $5.6 billion.
(4) 
Amounts represent instruments that are accounted for under the fair value option.
(5) 
Issuances represent loan originations and mortgage servicing rights retained following securitizations or whole-loan sales.
(6) 
Other assets is primarily comprised of certain long-term fixed-rate margin loans that are accounted for under the fair value option and certain private equity investments.

During the three months ended September 30, 2015, the transfers into Level 3 included $242 million of trading account assets and $264 million of long-term debt. Transfers into Level 3 for trading account assets were primarily the result of decreased availability of third-party prices for certain corporate debt securities. Transfers into Level 3 for long-term debt were primarily due to changes in the impact of unobservable inputs on the value of certain structured liabilities. Transfers occur on a regular basis for these long-term debt instruments due to changes in the impact of unobservable inputs on the value of the embedded derivative in relation to the instrument as a whole.

During the three months ended September 30, 2015, the transfers out of Level 3 included $249 million of trading account assets and $660 million of long-term debt. Transfers out of Level 3 for trading account assets were primarily the result of increased market liquidity and price observability for certain corporate debt securities. Transfers out of Level 3 for long-term debt were primarily due to changes in the impact of unobservable inputs on the value of certain structured liabilities.

In the tables above, instruments backed by residential real estate assets include RMBS, whole loans and mortgage CDOs. Commercial loans, debt securities and other include corporate CLOs and CDOs, commercial loans and bonds, and securities backed by non-real estate assets. Structured liabilities primarily include equity-linked notes that are accounted for under the fair value option.

In addition to the instruments in the tables above, the Corporation held instruments consisting primarily of certain direct private equity investments and private equity funds that were classified as Level 3 and reported within other assets. Valuations of direct private equity investments are based on the most recent company financial information. Inputs generally include market and acquisition comparables, entry level multiples, as well as other variables. The Corporation selects a valuation methodology (e.g., market comparables) for each investment and, in certain instances, multiple inputs are weighted to derive the most representative value. Discounts are applied as appropriate to consider the lack of liquidity and marketability versus publicly-traded companies. For private equity funds, fair value is determined using the net asset value as provided by the individual fund's general partner.

The Corporation uses multiple market approaches in valuing certain of its Level 3 financial instruments. For example, market comparables and discounted cash flows are used together. For a given product, such as corporate debt securities, market comparables may be used to estimate some of the unobservable inputs and then these inputs are incorporated into a discounted cash flow model. Therefore, the balances disclosed encompass both of these techniques.

The level of aggregation and diversity within the products disclosed in the tables result in certain ranges of inputs being wide and unevenly distributed across asset and liability categories. At September 30, 2015 and December 31, 2014, weighted averages are disclosed for all loans, securities, structured liabilities and net derivative assets.

For more information on the inputs and techniques used in the valuation of MSRs, see Note 17 – Mortgage Servicing Rights.

Sensitivity of Fair Value Measurements to Changes in Unobservable Inputs

Loans and Securities

For instruments backed by residential real estate assets and commercial loans, debt securities and other, a significant increase in market yields, default rates, loss severities or duration would result in a significantly lower fair value for long positions. Short positions would be impacted in a directionally opposite way. The impact of changes in prepayment speeds would have differing impacts depending on the seniority of the instrument and, in the case of CLOs, whether prepayments can be reinvested.

For auction rate securities, a significant increase in price would result in a significantly higher fair value.

Structured Liabilities and Derivatives

For credit derivatives, a significant increase in market yield, including spreads to indices, upfront points (i.e., a single upfront payment made by a protection buyer at inception), credit spreads, default rates or loss severities would result in a significantly lower fair value for protection sellers and higher fair value for protection buyers. The impact of changes in prepayment speeds would have differing impacts depending on the seniority of the instrument and, in the case of CLOs, whether prepayments can be reinvested.

Structured credit derivatives, which include tranched portfolio CDS and derivatives with derivative product company (DPC) and monoline counterparties, are impacted by credit correlation, including default and wrong-way correlation. Default correlation is a parameter that describes the degree of dependence among credit default rates within a credit portfolio that underlies a credit derivative instrument. The sensitivity of this input on the fair value varies depending on the level of subordination of the tranche. For senior tranches that are net purchases of protection, a significant increase in default correlation would result in a significantly higher fair value. Net short protection positions would be impacted in a directionally opposite way. Wrong-way correlation is a parameter that describes the probability that as exposure to a counterparty increases, the credit quality of the counterparty decreases. A significantly higher degree of wrong-way correlation between a DPC counterparty and underlying derivative exposure would result in a significantly lower fair value.

For equity derivatives, commodity derivatives, interest rate derivatives and structured liabilities, a significant change in long-dated rates, volatilities and correlation inputs (e.g., the degree of correlation between an equity security and an index, between two different commodities, between two different interest rates, or between interest rates and foreign exchange rates) would result in a significant impact to the fair value; however, the magnitude and direction of the impact depends on whether the Corporation is long or short the exposure.
Nonrecurring Fair Value

The Corporation holds certain assets that are measured at fair value, but only in certain situations (e.g., impairment) and these measurements are referred to herein as nonrecurring. The amounts below represent assets still held as of the reporting date for which a nonrecurring fair value adjustment was recorded during the three and nine months ended September 30, 2015 and 2014.

Includes $72 million and $146 million of losses on loans that were written down to a collateral value of zero during the three and nine months ended September 30, 2015 compared to losses of $71 million and $233 million for the same periods in 2014.
(2) 
Amounts are included in other assets on the Consolidated Balance Sheet and represent the carrying value of foreclosed properties that were written down subsequent to their initial classification as foreclosed properties. Losses on foreclosed properties include losses taken during the first 90 days after transfer of a loan to foreclosed properties.
(3) 
Excludes $1.3 billion and $1.1 billion of properties acquired upon foreclosure of certain government-guaranteed loans (principally FHA-insured loans) as of September 30, 2015 and 2014.

Instruments backed by residential real estate assets represent residential mortgages where the loan has been written down to the fair value of the underlying collateral. In addition to the instruments disclosed in the table above, the Corporation holds foreclosed residential properties where the fair value is based on unadjusted third-party appraisals or broker price opinions. Appraisals are generally conducted every 90 days. Factors considered in determining the fair value include geographic sales trends, the value of comparable surrounding properties as well as the condition of the property.
