Fair Value

3 Months Ended

Mar. 31, 2013

We use fair value measurements for the initial recording of certain assets and liabilities and periodic remeasurement of certain assets and liabilities on a recurring or nonrecurring basis.

Fair Value Measurement

Fair value measurement guidance defines fair value, establishes a framework for measuring fair value and sets forth disclosures around fair value measurements. This guidance applies whenever other accounting guidance requires or permits assets or liabilities to be measured at fair value. The guidance establishes a three-level fair value hierarchy that prioritizes the inputs into the valuation techniques used to measure fair value. The fair value hierarchy gives the highest priority, Level 1, to measurements based on unadjusted quoted prices in active markets for identical assets or liabilities. The next highest priority, Level 2, is given to measurements of assets and liabilities based on limited observable inputs or observable inputs for similar assets and liabilities. The lowest priority, Level 3, is given to measurements based on unobservable inputs.

Recurring Changes in Fair Value

The following tables display our assets and liabilities measured in our condensed consolidated balance sheets at fair value on a recurring basis subsequent to initial recognition, including instruments for which we have elected the fair value option as of March 31, 2013 and December 31, 2012.

Transfers out of Level 3 consisted primarily of Fannie Mae MBS and private-label mortgage-related securities backed by Alt-A loans. Prices for these securities were obtained from multiple third-party vendors supported by market observable inputs. Transfers into Level 3 consisted primarily of private-label mortgage-related securities backed by Alt-A loans. Prices for these securities are based on inputs from a single source or inputs that were not readily observable.

Valuation techniques for which no unobservable inputs are disclosed generally reflect the use of third-party pricing services or dealers, and the range of unobservable inputs applied by these sources is not readily available or cannot be reasonably estimated. Where we have disclosed unobservable inputs for consensus and single vendor techniques, those inputs are based on our validations performed at the security level using discounted cash flows.


⁽²⁾	Includes Fannie Mae, Freddie Mac and Ginnie Mae securities.

The following tables display valuation techniques for our Level 3 assets measured at fair value on a nonrecurring basis as of March 31, 2013 and December 31, 2012. The significant unobservable inputs related to these techniques primarily relate to collateral dependent valuations. The related ranges and weighted averages are not meaningful when aggregated as they vary significantly from property to property.

We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The following is a description of the valuation techniques we use for fair value measurement and disclosure as well as our basis for classifying these measurements as Level 1, Level 2 or Level 3 of the valuation hierarchy.

Cash Equivalents, Trading Securities and Available-for-Sale Securities

These securities are recorded in our condensed consolidated balance sheets at fair value on a recurring basis. Fair value is measured using quoted market prices in active markets for identical assets, when available.

A description of our securities valuation techniques is as follows:

Single Vendor: This valuation technique utilizes one vendor price to estimate fair value. We generally validate these observations of fair value through the use of a discounted cash flow technique whose unobservable inputs (for example, default rates) are disclosed in the table above.

Consensus: This technique utilizes an average of two or more vendor prices for similar securities. We generally validate these observations of fair value through the use of a discounted cash flow technique whose unobservable inputs (for example, default rates) are disclosed in the table above.

Discounted Cash Flow: In the absence of prices provided by third-party pricing services supported by observable market data, we estimate the fair value of a portion of our securities using a discounted cash flow technique that uses inputs such as default rates, prepayment speeds, loss severity and spreads based on market assumptions where available.

We classify securities whose values are based on quoted market prices in active markets for identical assets as Level 1 of the valuation hierarchy. We classify securities as Level 2 of the valuation hierarchy if quoted market prices in active markets for identical assets are not available. For all valuation techniques used for securities where there is limited activity or less transparency around these inputs to the valuation, these securities are classified as Level 3 of the valuation hierarchy.

For agency and private-label securities, an increase in unobservable prepayment speeds in isolation would generally result in an increase in fair value, and an increase in unobservable spreads, severity rates or default rates in isolation would generally result in a decrease in fair value. For mortgage revenue bonds classified as Level 3 of the valuation hierarchy, an increase in unobservable spreads would result in a decrease in fair value. Although the sensitivities of the fair value of our recurring Level 3 securities of the valuation hierarchy to various unobservable inputs are discussed above in isolation, interrelationships exist among these inputs such that a change in one unobservable input typically results in a change to one or more of the other inputs.

Mortgage Loans Held for Investment

The majority of HFI loans are reported in our condensed consolidated balance sheets at the principal amount outstanding, net of cost basis adjustments and an allowance for loan losses. We estimate the fair value of HFI loans using the build-up and consensus valuation techniques, as discussed below, for periodic disclosure of financial instruments as required by GAAP. For our remaining loans, which include those containing embedded derivatives that would otherwise require bifurcation and consolidated loans of senior-subordinated trust structures, we elected the fair value option and therefore, we record these loans at fair value in our condensed consolidated balance sheets. We measure these loans on a recurring basis using the build-up, consensus, discounted cash flow and single vendor price techniques. Certain impaired loans are measured at fair value on a nonrecurring basis by using the fair value of their underlying collateral. Specific techniques used include internal models, broker price opinions and appraisals.

A description of our loan valuation techniques is as follows:

Build-Up: The fair value of performing loans represents an estimate of the prices we would receive if we were to securitize those loans and is determined based on comparisons to Fannie Mae MBS with similar characteristics, either on a pool or loan level. We use the observable market values of our Fannie Mae MBS determined primarily from third-party pricing services, quoted market prices in active markets for similar securities, and other observable market data as a base value. In the build-up valuation technique we start with the base value for our Fannie Mae MBS then we add or subtract the fair value of the associated guaranty asset, guaranty obligation (“GO”) and master servicing arrangement. We set the GO equal to the estimated fair value we would receive if we were to issue our guaranty to an unrelated party in a stand-alone arm’s length transaction at the measurement date. We estimate the fair value of the GO using our internal GO valuation models, which calculate the present value of expected cash flows based on management’s best estimate of certain key assumptions such as current mark-to-market LTV ratios, future house prices, default rates, severity rates and required rate of return. We may further adjust the model values based on our current market pricing when such transactions reflect credit characteristics that are similar to our outstanding GO. These loans are generally classified as Level 2 of the valuation hierarchy to the extent that significant inputs are observable. To the extent that unobservable inputs are significant, the loans are classified as Level 3 of the valuation hierarchy.

Consensus: The fair value of single-family nonperforming loans represents an estimate of the prices we would receive if we were to sell these loans in the nonperforming whole-loan market. These nonperforming loans are either two or more months delinquent, in an open modification period, or in a closed modification state (both performing and nonperforming in accordance with the loan’s modified terms). We calculate the fair value of nonperforming loans based on assumptions about key factors, including collateral value and mortgage insurance repayment. Collateral value is derived from the current estimated mark-to-market LTV ratio of the individual loan along with a state-level distressed property sales discount. The fair value of mortgage insurance is estimated by taking the loan level coverage and adjusting it by the expected claims paying ability of the associated mortgage insurer. The expected claims paying abilities used for estimating the fair value of mortgage insurance are consistent with our credit loss forecast. Using these assumptions, along with indicative bids for a representative sample of nonperforming loans, we estimate the fair value. The bids on sample loans are obtained from multiple active market participants. Fair value is estimated from the extrapolation of these indicative sample bids plus an amount for the recovery of any associated mortgage insurance estimated through our GO valuation models as described above. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

Discounted Cash Flow: We estimate the fair value of a portion of our senior-subordinated trust structures using discounted cash flow at the security level as a proxy for estimating loan fair value. This valuation technique uses unobservable inputs such as prepayment speeds, default rates, spreads, and loss severities to estimate the fair value of our securities. These inputs are weighted in a model that calculates the expected cash flow of the security which is used as the basis of fair value. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

Single Vendor: We estimate the fair value of a portion of our senior-subordinated trust structures using the single vendor valuation technique at the security level as a proxy for estimating loan fair value. This valuation technique estimates fair value based upon prices received from one specific vendor. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

Internal Model: We estimate the fair value of a portion of our single-family nonperforming loans using the value of the underlying collateral. The inputs into this internal model include property level data such as prior sales prices, tax assessment values, property characteristics, and historical foreclosure sales data. This internal model takes one of two approaches when valuing foreclosed properties. The first approach relies on comparable foreclosed property sales, where the value of the target property is the weighted average price of comparable foreclosed property sales. The weights in the comparable sales approach are determined by various factors such as geographic distance, transaction time, and the value difference. The second approach relies on model calibrations that consider the target property’s attributes such as prior sales prices, tax assessment values, and property characteristics to derive the foreclosed property values. In the second approach, we build separate predictive models for each Metropolitan Statistical Area (“MSA”). Specifically, we use data on prior sales prices, tax assessment values, property characteristics, and historical foreclosure sales to calibrate the models in each MSA. We can use the available data about that property and our MSA-level model to estimate the fair value for a given property. The majority of the internal model valuations come from the comparable sales approach. The determination of whether the internal model valuations in a particular geographic area should use the comparable sales approach or model calibration is based on the quarterly evaluation of these two approaches for valuation accuracy. The unobservable inputs used in this technique include model weights based upon geographic distance, transaction time, and metropolitan statistics. When a physical address is not available, we estimate fair value using state-average foreclosed property values. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

Appraisals: For a portion of our multifamily loans, we use appraisals to estimate the fair value of the loan. There are three approaches used to estimate fair value of a specific property: (1) cost, (2) income capitalization and (3) sales comparison. This technique uses an average of the three estimates. The cost approach uses the insurable value as a basis. The unobservable inputs used in this model include the estimated cost to construct or replace multifamily properties in the closest localities available. The income capitalization approach estimates the fair value using the present value of the future cash flow expectations by applying an appropriate overall capitalization rate to the forecasted net operating income. The significant unobservable inputs used in this calculation include rental income, fees associated with rental income, expenses associated with the property including taxes, payroll, insurance and other items, and capitalization rates, which are determined through market extraction and the debt service coverage ratio. The sales comparison approach compares the prices paid for similar properties, the prices asked by owners and offers made. The unobservable inputs to this methodology include ratios of sales prices to annual gross income, price paid per unit and adjustments made based on financing, conditions of sale, and physical characteristics of the property. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

Broker Price Opinion (“BPO”): For a portion of our multifamily loans, we use BPO to estimate the fair value of the loan. This technique uses both current property value and the property value adjusted for stabilization and market conditions. These approaches compute net operating income based on current rents and expenses and use a range of market capitalization rates to estimate property value. The unobservable inputs used in this technique are property net operating income and market capitalization rates to estimate property value. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

Asset Manager Estimate (“AME”): For a portion of our multifamily loans, AME is used to estimate the fair value of the loan. This technique uses the net operating income and tax assessments of the specific property as well as MSA-specific market capitalization rates and average per unit sales values to estimate property fair value. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

An increase in prepayment speeds in isolation would generally result in an increase in the fair value of our mortgage loans classified as Level 3 of the valuation hierarchy, and an increase in severity rates, default rates, or spreads in isolation would generally result in a decrease in fair value. Although the sensitivities of the fair value of mortgage loans classified as Level 3 of the valuation hierarchy to various unobservable inputs are discussed above in isolation, interrelationships exist among these inputs such that a change in one unobservable input typically results in a change to one or more of the other inputs.

Acquired Property, Net and Other Assets

Acquired property, net represents foreclosed property received in full satisfaction of a loan net of a valuation allowance. Acquired property is initially recorded in our condensed consolidated balance sheets at its fair value less its estimated cost to sell. The initial fair value of foreclosed properties is determined using a hierarchy based on the reliability of available information. The hierarchy for single-family acquired property includes accepted offers, appraisals, broker price opinions and proprietary home price model values. The hierarchy for multifamily acquired property includes accepted offers, appraisals, and broker price opinions. We consider an accepted offer on a specific foreclosed property to be the best estimate of its fair value. If we have not accepted an offer on the property we use the highest available valuation methodology as described in our valuation hierarchy to determine fair value. While accepted offers represent an agreement in principle to transact, a significant portion of these agreements do not get executed for various reasons, and are therefore classified as Level 3 of the valuation hierarchy.

Third-party valuations can be obtained from either an appraisal or a broker price opinion. These valuations are kept current using a monthly walk forward process that updates them for any change in the value of the property. When accepted offers or third-party valuations are not available, we generally utilize the home price values determined using an internal model.

Subsequent to initial measurement, the foreclosed properties that we intend to sell are reported at the lower of the carrying amount or fair value less estimated costs to sell. Foreclosed properties classified as held for use, included in “Other Assets” in our condensed consolidated balance sheets, are depreciated and impaired when circumstances indicate that the carrying amount of the property is no longer recoverable. The fair values of our single-family foreclosed properties subsequent to initial measurement are determined using the same information hierarchy used for the initial fair value measurement.

The most commonly used techniques in our valuation of acquired property are proprietary home price model and appraisals (both current and walk forward). Based on the number of properties measured as of March 31, 2013, these methodologies comprised approximately 73% of our valuations, while accepted offers comprised approximately 25% of our valuations. Based on the number of properties measured as of December 31, 2012, these methodologies comprised approximately 78% of our valuations, while accepted offers comprised approximately 20% of our valuations.

Acquired property is classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

A description of our acquired property valuation techniques is as follows:

Single-family acquired property valuation techniques

Appraisal: An appraisal is an estimate of the value of a specific property by a certified or licensed appraiser, in accordance with the Uniform Standards of Professional Appraisal Practice. Data most commonly used is from the local Multiple Listing Service and includes properties currently listed for sale, properties under contract, and closed transactions. The appraiser performs an analysis that starts with these data points and then adjusts for differences between the comparable properties and the property being appraised, to arrive at an estimated value for the specific property. Adjustments are made for differences between comparable properties for unobservable inputs such as square footage, location, and condition of the property. The appraiser typically uses recent historical data for the estimate of value.

Broker Price Opinion: This technique provides an estimate of what the property is worth based upon a real estate broker’s knowledge. The broker uses research of pertinent data in the appropriate market, and a sales comparison approach that is similar to the appraisal process. The broker typically has insight into local market trends, such as the number of and terms of offers, lack of offers, increasing supply, shortage of inventory and overall interest in buying a home. This information, all of which is unobservable, is used along with recent and pending sales and current listings of similar properties to arrive at an estimate of value.

Appraisal and Broker Price Opinion Walk Forwards (“Walk Forwards”): We use these techniques to adjust appraisal and broker price opinion valuations for changing market conditions by applying a walk forward factor based on local price movements since the time the third-party value was obtained. The majority of third-party values are updated by comparing the difference in our internal home price model from the month of the original appraisal/broker price opinion to the current period and by applying the resulting percentage change to the original value. If a price is not determinable through our internal home price model, we use our zip code level home price index to update the valuations.

Internal Model: We use an internal model to estimate fair value for distressed properties. The valuation methodology and inputs used are described under “Mortgage Loans Held for Investment.”

Multifamily acquired property valuation techniques

Appraisals: We use this method to estimate property values for distressed properties. The valuation methodology and inputs used are described under “Mortgage Loans Held for Investment.”

Broker Price Opinions: We use this method to estimate property values for distressed properties. The valuation methodology and inputs used are described under “Mortgage Loans Held for Investment.”

Derivatives Assets and Liabilities (collectively “Derivatives”)

Derivatives are recorded in our condensed consolidated balance sheets at fair value on a recurring basis. The valuation process for the majority of our risk management derivatives uses observable market data provided by third-party sources, resulting in Level 2 classification of the valuation hierarchy.

A description of our derivatives valuation techniques is as follows:

Internal Model: We use internal models to value interest rate swaps which are valued by referencing yield curves derived from observable interest rates and spreads to project and discount swap cash flows to present value. Option-based derivatives use an internal model that projects the probability of various levels of interest rates by referencing swaption volatilities provided by market makers/dealers. The projected cash flows of the underlying swaps of these option-based derivatives are discounted to present value using yield curves derived from observable interest rates and spreads.

Dealer Mark: Certain highly complex structured swaps primarily use a single dealer mark due to lack of transparency in the market and may be modeled using observable interest rates and volatility levels as well as significant unobservable assumptions, resulting in Level 3 classification of the valuation hierarchy. Mortgage commitment derivatives that use observable market data, quotes and actual transaction price levels adjusted for market movement, are typically classified as Level 2 of the valuation hierarchy. To the extent mortgage commitment derivatives include adjustments for market movement that cannot be corroborated by observable market data, we classify them as Level 3 of the valuation hierarchy.

Debt

The majority of debt of Fannie Mae is recorded in our condensed consolidated balance sheets at the principal amount outstanding, net of cost basis adjustments. We elected the fair value option for certain structured debt instruments, which are recorded in our condensed consolidated balance sheets at fair value on a recurring basis.

We use third-party pricing services that reference observable market data such as interest rates and spreads to measure the fair value of debt, and thus classify that debt as Level 2 of the valuation hierarchy.

A description of our debt valuation techniques is as follows:

Discounted Cash Flow: For structured debt instruments that are not valued by third-party pricing services, cash flows are evaluated taking into consideration any structured derivatives through which we have swapped out of the structured features of the notes. The resulting cash flows are discounted to present value using a yield curve derived from market prices observed for Fannie Mae Benchmark Notes and adjusted to reflect fair values at the offer side of the market. Market swaption volatilities are also referenced for the valuation of callable structured debt instruments. Since the derivatives considered in the valuations of these structured debt instruments are classified as Level 3 of the valuation hierarchy, the valuations of the structured debt instruments result in a Level 3 classification.

Consensus: Certain consolidated MBS debt with embedded derivatives is recorded in our condensed consolidated balance sheets at fair value on a recurring basis. Consolidated MBS debt is traded in the market as MBS assets. Accordingly, we estimate the fair value of our consolidated MBS debt using quoted market prices in active markets for similar liabilities when traded as assets. For a portion of our senior-subordinated trust structures, we estimate the fair value using the average of two or more vendor valuation techniques at the security level as a proxy for estimating debt fair value. This valuation technique estimates fair value based upon prices received from more than one vendor. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

Single Vendor: Certain consolidated MBS debt with embedded derivatives is recorded in our condensed consolidated balance sheets at fair value on a recurring basis. Consolidated MBS debt is traded in the market as MBS assets. Accordingly, we estimate the fair value of our consolidated MBS debt using quoted market prices in active markets for similar liabilities when traded as assets. For a portion of our senior-subordinated trust structures, we estimate the fair value using the single vendor valuation technique at the security level as a proxy for estimating debt fair value. This valuation technique estimates fair value based upon prices received from one specific vendor. The valuation methodology and inputs used in estimating the fair value of MBS assets are described under “Cash Equivalents, Trading Securities and Available-for-Sale Securities.” These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

Valuation Control Processes

We have control processes that are designed to ensure that our fair value measurements are appropriate and reliable, that they are based on observable inputs wherever possible and that our valuation approaches are consistently applied and the assumptions used are reasonable. Our control processes consist of a framework that provides for a segregation of duties and oversight of our fair value methodologies and valuations, as well as validation procedures.

The Pricing Group within our Finance Division is responsible for estimating the fair value of the majority of our financial assets and financial liabilities. These fair values are verified by our Price Verification Group, which is a control group separate from the group responsible for obtaining prices. Our Enterprise Risk Analytics Group develops models that are used in estimating the fair value of assets and liabilities for financial reporting purposes. In addition, our Model Oversight Committee (“MOC”) facilitates the cross-functional coordination and effectiveness of our modeling efforts in terms of research, model use and risk governance. The MOC is comprised of senior representatives from Underwriting and Pricing, Capital Markets, Credit Portfolio Management, Enterprise Risk Management and Finance and is co-chaired by our Chief Risk Officer and our Head of Enterprise Business Analytics. Our Model Risk Oversight Group is responsible for establishing risk management controls and for reviewing, validating and approving models used in the determination of fair value measurements for financial reporting. Fair value measurements for acquired property and collateral dependent loans are determined by other valuation groups in the Finance division.

Our Valuation Oversight Committee (“VOC”) includes senior representation from our Capital Markets segment, our Enterprise Risk Office and our Finance division, and is responsible for providing overall governance for our valuation processes and results. The composition of the VOC is determined by the VOC chair, our Chief Financial Officer, with the objective of obtaining appropriate representation from Finance, Enterprise Risk Management and select business units within Fannie Mae. Based on its review of valuation methodologies and fair value results for various financial instruments used for financial reporting, the VOC is responsible for advising the VOC chair, who has the ultimate responsibility over all valuation processes and results. The VOC also reviews trend analysis for various financial assets and liabilities on a quarterly basis.

We use third-party vendor prices and dealer quotes to estimate fair value of some of our financial assets and liabilities. Third-party vendor prices are primarily used to estimate fair value for trading securities, available-for-sale securities, debt of Fannie Mae, and consolidated MBS debt. Our Pricing Group performs various review and validation procedures prior to utilizing these prices in our fair value estimation process. We verify selected prices, using a variety of methods, including corroborating the prices by reference to other independent market data, such as non-binding broker or dealer quotations, relevant benchmark indices, and prices of similar instruments. We also review prices for reasonableness based on variations from prices provided in previous periods, comparing prices to internally estimated prices, using primarily a discounted cash flow approach, and conducting relative value comparisons based on specific characteristics of securities.

We have discussions with the pricing services as part of our due diligence process in order to maintain a current understanding of the valuation processes and related assumptions and inputs that these vendors use in developing prices. The prices provided to us by third-party pricing services reflect the existence of market reliance upon credit enhancements, if any, and the current lack of liquidity in the marketplace. If we determine that a price provided to us is outside established parameters, we will further examine the price, including having follow-up discussions with the pricing service or dealer. If we conclude that a price is not valid, we will adjust the price for various factors, such as liquidity, bid-ask spreads and credit considerations. All of these procedures are executed before we use the prices in preparing our financial statements.

Our Price Verification Group is responsible for performing monthly independent price verification, primarily related to financial assets and financial liabilities that are priced by our Pricing Group. This is generally accomplished by comparing the value that the Price Verification Group obtains through its own sources and methods with values provided by the Pricing Group. Alternatively, the Price Verification Group may perform reviews of the assumptions used by the Pricing Group to estimate the fair value of products we hold that have material estimation risk because observable market-based inputs do not exist. This group provides an update to the VOC on results, relevant market information and pricing trends, and significant valuation challenges and resolution of those challenges with the Pricing Group on a quarterly basis.

We have an internal property valuation function that utilizes an internal model to compare the values received on a property and assign a risk rating based on several factors including the deviation between the various values. Property valuations with risk ratings above a specified threshold are reviewed for reasonableness by a team of property valuation experts. The internal model that is used to assign a risk rating and the threshold specified is subject to VOC oversight. In addition, our Quality Control Group reviews the overall work performed and inspects a portion of the properties in major markets, for which the third-party valuations are obtained, in order to assess the quality of the valuations.

We calibrate the performance of our proprietary distressed home price model using actual offers in recently observed transactions. The model’s performance is reviewed on a monthly basis by the REO valuation team and compared quarterly to specific model performance thresholds. The results of the validation are regularly reviewed with the VOC.

Our Appraisal Review Group reviews appraisals to determine whether they have been performed in accordance with appraisal standards and the results are consistent with our observed transactions on similar properties. We and/or third-party servicers review broker price opinions to determine whether the values provided are consistent with our observed transactions on similar properties. We conduct quarterly portfolio reviews, annual audits and periodic reviews of the counterparties that provide services to review broker price opinions. In addition, valuation results and trend analyses are reviewed at least monthly by REO management.

Fair Value of Financial Instruments

The following table displays the carrying value and estimated fair value of our financial instruments as of March 31, 2013 and December 31, 2012. The fair value of financial instruments we disclose includes commitments to purchase multifamily and single-family mortgage loans, which are off-balance sheet financial instruments that we do not record in our condensed consolidated balance sheets. The fair values of these commitments are included as “Mortgage loans held for investment, net of allowance for loan losses.” The disclosure excludes certain financial instruments, such as plan obligations for pension and postretirement health care benefits, employee stock option and stock purchase plans, and also excludes all non-financial instruments. As a result, the fair value of our financial assets and liabilities does not represent the underlying fair value of our total consolidated assets and liabilities.

Financial Instruments for which fair value approximates carrying value—We hold certain financial instruments that are not carried at fair value but for which the carrying value approximates fair value due to the short-term nature and negligible credit risk inherent in them. These financial instruments include cash and cash equivalents, the majority of advances to lenders and federal funds and securities sold/purchased under agreements to repurchase/resell (exclusive of dollar roll repurchase transactions).

Federal funds and securities sold/purchased under agreements to repurchase/resell—The carrying value for the majority of these specific instruments approximates the fair value due to the short-term nature and the negligible inherent credit risk, as they involve the exchange of liquid collateral. Were we to calculate the fair value of these instruments we would use observable inputs resulting in Level 2 classification.

Mortgage Loans Held for Sale—Loans are reported at the lower of cost or fair value in our condensed consolidated balance sheets. The valuation methodology and inputs used in estimating the fair value of HFS loans are the same as for our HFI loans and are described under “Fair Value Measurement—Mortgage Loans Held for Investment” and these loans are classified as Level 2 of the valuation hierarchy to the extent that significant inputs are observable. To the extent that significant inputs are unobservable, the loans are classified within Level 3 of the valuation hierarchy.

Advances to Lenders—The carrying value for the majority of our advances to lenders approximates fair value due to the short-term nature and the negligible inherent credit risk. Were we to calculate the fair value of these instruments we would use discounted cash flow models that use observable inputs such as spreads based on market assumptions, resulting in Level 2 classification.

Advances to lenders also include loans for which the carrying value does not approximate fair value. These loans do not qualify for Fannie Mae MBS securitization and are valued using market-based techniques including credit spreads, severities and prepayment speeds for similar loans, through third-party pricing services or through a model approach incorporating both interest rate and credit risk simulating a loan sale via a synthetic structure. We classify these valuations as Level 3 given that significant inputs are not observable or are determined by extrapolation of observable points.

Guaranty Assets and Buy-ups—Guaranty assets related to our portfolio securitizations are recorded in our condensed consolidated balance sheets at fair value on a recurring basis and are classified within Level 3 of the valuation hierarchy. Guaranty assets in lender swap transactions are recorded in our condensed consolidated balance sheets at the lower of cost or fair value. These assets, which are measured at fair value on a nonrecurring basis, are classified within Level 3 of the fair value hierarchy.

We estimate the fair value of guaranty assets based on the present value of expected future cash flows of the underlying mortgage assets using management’s best estimate of certain key assumptions, which include prepayment speeds, forward yield curves, and discount rates commensurate with the risks involved. These cash flows are projected using proprietary prepayment, interest rate and credit risk models. Because guaranty assets are like an interest-only income stream, the projected cash flows from our guaranty assets are discounted using one-month LIBOR plus an option-adjusted spread that is calibrated using a representative sample of interest-only swaps that reference Fannie Mae MBS. We believe the remitted fee income is less liquid than interest-only swaps and more like an excess servicing strip. We take a further discount of the present value for these liquidity considerations. This discount is based on market quotes from dealers.

The fair value of the guaranty assets includes the fair value of any associated buy-ups, which is estimated in the same manner as guaranty assets but is recorded separately as a component of “Other assets” in our condensed consolidated balance sheets.

Guaranty Obligations—The fair value of all guaranty obligations, measured subsequent to their initial recognition, is our estimate of a hypothetical transaction price we would receive if we were to issue our guaranty to an unrelated party in a standalone arm’s-length transaction at the measurement date. These obligations are classified within Level 3. The valuation methodology and inputs used in estimating the fair value of the guaranty obligation are described under “Fair Value Measurement—Mortgage Loans Held for Investment, Build-up.”

HARP Loans—We measure the fair value of loans that are delivered under the Home Affordable Refinance Program (“HARP”) using a modified build-up approach while the loan is performing. Under this modified approach, we set the credit component of the consolidated loans (that is, the guaranty obligation) equal to the compensation we would currently receive for a loan delivered to us under the program because the total compensation for these loans is equal to their current exit price in the GSE securitization market. For a description of the build-up valuation methodology, refer to “Fair Value Measurement—Mortgage Loans Held for Investment.” We will continue to use this pricing methodology as long as the HARP program is available to market participants. If, subsequent to delivery, the refinanced loan becomes past due or is modified as a part of a troubled debt restructuring, the fair value of the guaranty obligation is then measured consistent with other loans that have these characteristics.

The total compensation that we receive for the delivery of a HARP loan reflects the pricing that we are willing to offer because HARP is a part of a broader government program intended to provide assistance to homeowners and prevent foreclosures. If these benefits were not reflected in the pricing for these loans (that is, if the loans were valued using our standard build-up approach), the fair value disclosed in the table above would be lower by $9.2 billion as of March 31, 2013. The total fair value of the loans in our retained mortgage portfolio that have been refinanced under HARP as of March 31, 2013 as presented in the table above is $279.8 billion.

Fair Value Option

We elected the fair value option for loans which contain embedded derivatives that would otherwise require bifurcation. Under the fair value option, we elected to carry these instruments at fair value instead of bifurcating the embedded derivative from the respective loan.

We elected the fair value option for all long-term structured debt instruments that are issued in response to specific investor demand and have interest rates that are based on a calculated index or formula and are economically hedged with derivatives at the time of issuance. By electing the fair value option for these instruments, we are able to eliminate the volatility in our results of operations that would otherwise result from the accounting asymmetry created by recording these structured debt instruments at cost while recording the related derivatives at fair value.

We elected the fair value option for the financial assets and liabilities of the consolidated senior-subordinate trust structures. By electing the fair value option for these instruments, we are able to eliminate the volatility in our results of operations that would otherwise result from different accounting treatment between loans at cost and debt at cost.

Interest income for the mortgage loans is recorded in “Mortgage loans interest income” and interest expense for the debt instruments is recorded in “Long-term debt interest expense” in our condensed consolidated statements of operations and comprehensive income.

The following table displays the fair value and unpaid principal balance of the financial instruments for which we have made fair value elections as of March 31, 2013 and December 31, 2012.

Includes nonaccrual loans with a fair value of $323 million and $273 million as of March 31, 2013 and December 31, 2012, respectively. The difference between unpaid principal balance and the fair value of these nonaccrual loans as of March 31, 2013 and December 31, 2012 is $127 million and $189 million, respectively. Includes loans that are 90 days or more past due with a fair value of $434 million and $386 million as of March 31, 2013 and December 31, 2012, respectively. The difference between unpaid principal balance and the fair value of these 90 or more days past due loans as of March 31, 2013 and December 31, 2012 is $135 million and $201 million, respectively.


⁽²⁾	Includes interest-only debt instruments with no unpaid principal balance and a fair value of $93 million and $100 million as of March 31, 2013 and December 31, 2012, respectively.

Changes in Fair Value under the Fair Value Option Election

The following table displays fair value gains and losses, net, including changes attributable to instrument-specific credit risk, for loans and debt for which the fair value election was made. Amounts are recorded as a component of “Fair value gains, net” in our condensed consolidated statements of operations and comprehensive income for the three months ended March 31, 2013 and 2012.



	For the Three Months Ended March 31,
	2013											2012
	Loans			Long-Term Debt				Total Gains (Losses)				Loans			Long-Term Debt				Total Gains (Losses)
	(Dollars in millions)
Changes in instrument-specific credit risk	$	(65	)		$	(5	)		$	(70	)	$	66			$	(2	)		$	64
Other changes in fair value	(157		)		66				(91		)	(65		)		60				(5		)
Fair value (losses) gains, net	$	(222	)		$	61			$	(161	)	$	1			$	58			$	59

In determining the changes in the instrument-specific credit risk for loans, the changes in the associated credit-related components of these loans, primarily the guaranty obligation, were taken into consideration with the overall change in the fair value of the loans for which we elected the fair value option for financial instruments. In determining the changes in the instrument-specific credit risk for debt, the changes in Fannie Mae debt spreads to LIBOR that occurred during the period were taken into consideration with the overall change in the fair value of the debt for which we elected the fair value option for financial instruments. Specifically, cash flows are evaluated taking into consideration any derivatives through which Fannie Mae has swapped out of the structured features of the notes and thus created a floating-rate LIBOR-based debt instrument. The change in value of these LIBOR-based cash flows based on the Fannie Mae yield curve at the beginning and end of the period represents the instrument-specific risk.
