Fair Values of Assets and Liabilities

Note 13

Fair Values of Assets and Liabilities

The Company uses fair value measurements for the initial recording of certain assets and liabilities, periodic remeasurement of certain assets and liabilities, and disclosures. Derivatives, trading and available-for-sale investment securities, certain MLHFS and MSRs are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as loans held for sale, loans held for investment and certain other assets. These nonrecurring fair value adjustments typically involve application of lower-of-cost-or-fair value accounting or impairment write-downs of individual assets.

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. A fair value measurement reflects all of the assumptions that market participants would use in pricing the asset or liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, and the risk of nonperformance.

The Company groups its assets and liabilities measured at fair value into a three-level hierarchy for valuation techniques used to measure financial assets and financial liabilities at fair value. This hierarchy is based on whether the valuation inputs are observable or unobservable. These levels are:

Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 1 includes U.S. Treasury and exchange-traded instruments.

Level 2 – Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 includes debt securities that are traded less frequently than exchange-traded instruments and which are typically valued using third party pricing services; derivative contracts and other assets and liabilities, including securities, whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data; and MLHFS whose values are determined using quoted prices for similar assets or pricing models with inputs that are observable in the market or can be corroborated by observable market data.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. This category includes MSRs, certain debt securities and certain derivative contracts.

When the Company changes its valuation inputs for measuring financial assets and financial liabilities at fair value, either due to changes in current market conditions or other factors, it may need to transfer those assets or liabilities to another level in the hierarchy based on the new inputs used. The Company recognizes these transfers at the end of the reporting period that the transfers occur. During the nine months ended September 30, 2013 and 2012, there were no transfers of financial assets or financial liabilities between the hierarchy levels.

The Company has processes and controls in place to increase the reliability of estimates it makes in determining fair value measurements. Items quoted on an exchange are verified to the quoted price. Items provided by a third party pricing service are subject to price verification procedures as discussed in more detail in the specific valuation discussions provided in the section that follows. For fair value measurements modeled internally, the Company’s valuation models are subject to the Company’s Model Risk Governance Policy and Program, as maintained by the Company’s credit administration department. The purpose of model validation is to assess the accuracy of the models’ input, processing, and reporting components. All models are required to be independently reviewed and approved prior to being placed in use, and are subject to formal change control procedures. Under the Company’s Model Risk Governance Policy, models are required to be reviewed at least annually to ensure they are operating as intended. Inputs into the models are market observable inputs whenever available. When market observable inputs are not available, the inputs are developed based upon analysis of historical experience and evaluation of other relevant market data. Significant unobservable model inputs are subject to review by senior management in corporate functions, who are independent from the modeling. Significant unobservable model inputs are also compared to actual results, typically on a quarterly basis. Significant Level 3 fair value measurements are also subject to corporate-level review and are benchmarked to market transactions or other market data, when available. Additional discussion of processes and controls are provided in the valuation methodologies section that follows.

The following section describes the valuation methodologies used by the Company to measure financial assets and liabilities at fair value and for estimating fair value for financial instruments not recorded at fair value as required under disclosure guidance related to the fair value of financial instruments. In addition, the following section includes an indication of the level of the fair value hierarchy in which the assets or liabilities are classified. Where appropriate, the description includes information about the valuation models and key inputs to those models. During the nine months ended September 30, 2013 and 2012, there were no significant changes to the valuation techniques used by the Company to measure fair value.

Cash and Due From Banks The carrying value of cash and due from banks approximate fair value and are classified within Level 1. Fair value is provided for disclosure purposes only.

Federal Funds Sold and Securities Purchased Under Resale Agreements The carrying value of federal funds sold and securities purchased under resale agreements approximate fair value because of the relatively short time between the origination of the instrument and its expected realization and are classified within Level 2. Fair value is provided for disclosure purposes only.

Investment Securities When quoted market prices for identical securities are available in an active market, these prices are used to determine fair value and these securities are classified within Level 1 of the fair value hierarchy. Level 1 investment securities are predominantly U.S. Treasury securities.

For other securities, quoted market prices may not be readily available for the specific securities. When possible, the Company determines fair value based on market observable information, including quoted market prices for similar securities, inactive transaction prices, and broker quotes. These securities are classified within Level 2 of the fair value hierarchy. Level 2 valuations are generally provided by a third party pricing service. The Company reviews the valuation methodologies utilized by the pricing service and, on a quarterly basis, reviews the security level prices provided by the pricing service against management’s expectation of fair value, based on changes in various benchmarks and market knowledge from recent trading activity. Additionally, each quarter, the Company validates the fair value provided by the pricing services by comparing them to recent observable market trades (where available), broker provided quotes, or other independent secondary pricing sources. Prices obtained from the pricing service are adjusted if they are found to be inconsistent with observable market data. Level 2 investment securities are predominantly agency mortgage-backed securities, certain other asset-backed securities, municipal securities, corporate debt securities, agency debt securities and perpetual preferred securities.

The fair value of securities for which there are no market trades, or where trading is inactive as compared to normal market activity, are classified within Level 3 of the fair value hierarchy. The Company determines the fair value of these securities using a discounted cash flow methodology and incorporating observable market information, where available. These valuations are modeled by a unit within the Company’s treasury department. The valuations use assumptions regarding housing prices, interest rates and borrower performance. Inputs are refined and updated at least quarterly to reflect market developments and actual performance. The primary valuation drivers of these securities are the prepayment rates, default rates and default severities associated with the underlying collateral, as well as the discount rate used to calculate the present value of the projected cash flows. Level 3 fair values, including the assumptions used, are subject to review by senior management in corporate functions, who are independent from the modeling. The fair value measurements are also compared to fair values provided by third party pricing services, where available. Securities classified within Level 3 include non-agency mortgage-backed securities, non-agency commercial mortgage-backed securities, certain asset-backed securities, certain collateralized debt obligations and collateralized loan obligations and certain corporate debt securities.

Mortgage Loans Held For Sale MLHFS measured at fair value, for which an active secondary market and readily available market prices exist, are initially valued at the transaction price and are subsequently valued by comparison to instruments with similar collateral and risk profiles. MLHFS are classified within Level 2. Included in mortgage banking revenue was a $5 million net loss and a $241 million net gain for the three months ended September 30, 2013 and 2012, respectively, and a $326 million net loss and a $501 million net gain for the nine months ended September 30, 2013 and 2012, respectively, from the changes to fair value of these MLHFS under fair value option accounting guidance. Changes in fair value due to instrument specific credit risk were immaterial. Interest income for MLHFS is measured based on contractual interest rates and reported as interest income on the Consolidated Statement of Income. Electing to measure MLHFS at fair value reduces certain timing differences and better matches changes in fair value of these assets with changes in the value of the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting.

Loans The loan portfolio includes adjustable and fixed-rate loans, the fair value of which was estimated using discounted cash flow analyses and other valuation techniques. The expected cash flows of loans considered historical prepayment experiences and estimated credit losses and were discounted using current rates offered to borrowers of similar credit characteristics. Generally, loan fair values reflect Level 3 information. Fair value is provided for disclosure purposes only, with the exception of impaired collateral-based loans that are measured at fair value on a non-recurring basis utilizing the underlying collateral fair value.

Mortgage Servicing Rights MSRs are valued using a discounted cash flow methodology. Accordingly, MSRs are classified within Level 3. The Company determines fair value by estimating the present value of the asset’s future cash flows using prepayment rates, discount rates, and other assumptions. The MSR valuations, as well as the assumptions used, are developed by the mortgage banking division and are subject to review by senior management in corporate functions, who are independent from the modeling. The MSR valuations and assumptions are validated through comparison to trade information, publicly available data and industry surveys when available, and are also compared to independent third party valuations each quarter. Risks inherent in MSR valuation include higher than expected prepayment rates and/or delayed receipt of cash flows. There is minimal observable market activity for MSRs on comparable portfolios, and, therefore the determination of fair value requires significant management judgment. Refer to Note 5 for further information on MSR valuation assumptions.

Derivatives The majority of derivatives held by the Company are executed over-the-counter and are valued using standard cash flow, Black-Derman-Toy and Monte Carlo valuation techniques. The models incorporate inputs, depending on the type of derivative, including interest rate curves, foreign exchange rates and volatility. In addition, all derivative values incorporate an assessment of the risk of counterparty nonperformance, measured based on the Company’s evaluation of credit risk as well as external assessments of credit risk, where available. The Company monitors and manages its nonperformance risk by considering its ability to net derivative positions under master netting arrangements, as well as collateral received or provided under collateral arrangements. Accordingly, the Company has elected to measure the fair value of derivatives, at a counterparty level, on a net basis. The majority of the derivatives are classified within Level 2 of the fair value hierarchy, as the significant inputs to the models, including nonperformance risk, are observable. However, certain derivative transactions are with counterparties where risk of nonperformance cannot be observed in the market, and therefore the credit valuation adjustments result in these derivatives being classified within Level 3 of the fair value hierarchy. The credit valuation adjustments for nonperformance risk are determined by the Company’s treasury department using credit assumptions provided by credit administration. The credit assumptions are compared to actual results quarterly and are recalibrated as appropriate.

The Company also has commitments to purchase and originate mortgage loans that meet the accounting requirements of a derivative. These mortgage loan commitments are valued by pricing models that include market observable and unobservable inputs, which result in the commitments being classified within Level 3 of the fair value hierarchy. The unobservable inputs include assumptions about the percentage of commitments that actually become a closed loan and the MSR value that is inherent in the underlying loan value, both of which are developed by the Company’s mortgage banking division. The closed loan percentages for the mortgage loan commitments are monitored on an on-going basis, as these percentages are also used for the Company’s economic hedging activities. The inherent MSR value for the commitments are generated by the same models used for the Company’s MSRs and thus are subject to the same processes and controls as described for the MSRs above.

Other Financial Instruments Other financial instruments include cost method equity investments and community development and tax-advantaged related assets and liabilities. The majority of the Company’s cost method equity investments are in Federal Home Loan Bank and Federal Reserve Bank stock, whose carrying amounts approximate their fair value and are classified within Level 2. Investments in private equity and other limited partnership funds are estimated using fund provided net asset values. These equity investments are classified within Level 3. Fair value is provided for disclosure purposes only.

Community development and tax-advantaged investments generate a return primarily through the realization of federal and state income tax credits, with a duration typically equal to the period that the tax credits are realized. Asset balances primarily represent the assets of the underlying community development and tax-advantaged entities the Company consolidated per applicable authoritative accounting guidance. Liabilities of the underlying consolidated entities were included in long-term debt. The carrying value of the asset balances are a reasonable estimate of fair value and are classified within Level 3. Refer to Note 4 for further information on community development and tax-advantaged related assets and liabilities. Fair value is provided for disclosure purposes only.

Deposit Liabilities The fair value of demand deposits, savings accounts and certain money market deposits is equal to the amount payable on demand. The fair value of fixed-rate certificates of deposit was estimated by discounting the contractual cash flow using current market rates. Deposit liabilities are classified within Level 2. Fair value is provided for disclosure purposes only.

Short-term Borrowings Federal funds purchased, securities sold under agreements to repurchase, commercial paper and other short-term funds borrowed have floating rates or short-term maturities. The fair value of short-term borrowings was determined by discounting contractual cash flows using current market rates. Short-term borrowings are classified within Level 2. Included in short-term borrowings is the Company’s obligation on securities sold short, which is required to be accounted for at fair value per applicable accounting guidance. Fair value for other short-term borrowings is provided for disclosure purposes only.

Long-term Debt The fair value for most long-term debt was determined by discounting contractual cash flows using current market rates. Junior subordinated debt instruments were valued using market quotes. Long-term debt is classified within Level 2. Fair value is provided for disclosure purposes only.

Loan Commitments, Letters of Credit and Guarantees The fair value of commitments, letters of credit and guarantees represents the estimated costs to terminate or otherwise settle the obligations with a third party. Other loan commitments, letters of credit and guarantees are not actively traded, and the Company estimates their fair value based on the related amount of unamortized deferred commitment fees adjusted for the probable losses for these arrangements. These arrangements are classified within Level 3. Fair value is provided for disclosure purposes only.

Significant Unobservable Inputs of Level 3 Assets and Liabilities

The following section provides information on the significant inputs used by the Company to determine the fair value measurements of Level 3 assets and liabilities recorded at fair value on the Consolidated Balance Sheet. In addition, the following section includes a discussion of the sensitivity of the fair value measurements to changes in the significant inputs and a description of any interrelationships between these inputs for Level 3 assets and liabilities recorded at fair value on a recurring basis. The discussion below excludes nonrecurring fair value measurements of collateral value used for impairment measures for loans and other real estate owned. These valuations utilize third party appraisal or broker price opinions, and are classified as Level 3 due to the significant judgment involved.

Available-For-Sale Investment Securities The significant unobservable inputs used in the fair value measurement of the Company’s modeled Level 3 available-for-sale investment securities are prepayment rates, probability of default and loss severities associated with the underlying collateral, as well as the discount margin used to calculate the present value of the projected cash flows. Increases in prepayment rates for Level 3 securities will typically result in higher fair values, as increased prepayment rates accelerate the receipt of expected cash flows and reduce exposure to credit losses. Increases in the probability of default and loss severities will result in lower fair values, as these increases reduce expected cash flows. Discount margin is the Company’s estimate of the current market spread above the respective benchmark rate. Higher discount margin will result in lower fair values, as it reduces the present value of the expected cash flows.

Prepayment rates generally move in the opposite direction of market interest rates. In the current environment, an increase in the probability of default will generally be accompanied with an increase in loss severity, as both are impacted by underlying collateral values. Discount margins are influenced by market expectations about the security’s collateral performance, and therefore may directionally move with probability and severity of default; however, discount margins are also impacted by broader market forces, such as competing investment yields, sector liquidity, economic news, and other macroeconomic factors.

The following table shows the significant valuation assumption ranges for Level 3 available-for-sale investment securities at September 30, 2013:

(a) Prime securities are those designated as such by the issuer at origination. When an issuer designation is unavailable, the Company determines at acquisition date the categorization based on asset pool characteristics (such as weighted-average credit score, loan-to-value, loan type, prevalence of low documentation loans) and deal performance (such as pool delinquencies and security market spreads).
(b) Includes all securities not meeting the conditions to be designated as prime.

Mortgage Servicing Rights The significant unobservable inputs used in the fair value measurement of the Company’s MSRs are expected prepayments and the discount rate used to calculate the present value of the projected cash flows. Significant increases in either of these inputs in isolation would result in a significantly lower fair value measurement. Significant decreases in either of these inputs in isolation would result in a significantly higher fair value measurement. There is no direct interrelationship between prepayments and discount rate. Prepayment rates generally move in the opposite direction of market interest rates. Discount rates are generally impacted by changes in market return requirements.

The following table shows the significant valuation assumption ranges for MSRs at September 30, 2013:

Minimum Maximum Average

Expected prepayment

10 % 22 % 12 %

Discount rate

10 13 10

Derivatives The Company has two distinct Level 3 derivative portfolios: (i) the Company’s commitments to sell, purchase and originate mortgage loans that meet the requirements of a derivative, and (ii) the Company’s asset/liability and customer-related derivatives that are Level 3 due to unobservable inputs related to measurement of risk of nonperformance by the counterparty.

The significant unobservable inputs used in the fair value measurement of the Company’s derivative commitments to sell, purchase and originate mortgage loans are the percentage of commitments that actually become a closed loan and the MSR value that is inherent in the underlying loan value. A significant increase in the rate of loans that close would result in a larger derivative asset or liability. A significant increase in the inherent MSR value would result in an increase in the derivative asset or a reduction in the derivative liability. Expected loan close rates and the inherent MSR values are directly impacted by changes in market rates and will generally move in the same direction as interest rates.

The following table shows the significant valuation assumption ranges for the Company’s derivative commitments to sell, purchase and originate mortgage loans at September 30, 2013:

Minimum Maximum Average

Expected loan close rate

32 % 100 % 76 %

Inherent MSR value (basis points per loan)

46 219 108

The significant unobservable input used in the fair value measurement of certain of the Company’s asset/liability and customer-related derivatives is the credit valuation adjustment related to the risk of counterparty nonperformance. A significant increase in the credit valuation adjustment would result in a lower fair value measurement. A significant decrease in the credit valuation adjustment would result in a higher fair value measurement. The credit valuation adjustment is impacted by changes in the Company’s assessment of the counterparty’s credit position. At September 30, 2013, the minimum, maximum and average credit valuation adjustment as a percentage of the derivative contract fair value prior to adjustment was 0 percent, 95 percent and 6 percent, respectively.
