PART I—FINANCIAL INFORMATION

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

We have been under conservatorship, with the Federal Housing Finance Agency (“FHFA”)acting as conservator, since September 6, 2008. As conservator, FHFA succeeded toall rights, titles, powers and privileges of the company, and of any shareholder,officer or director of the company with respect to the company and its assets. Theconservator has since delegated specified authorities to our Board of Directors andhas delegated to management the authority to conduct our day-to-dayoperations. Our directors do not have any fiduciary duties to any person or entity except to the conservator and, accordingly, are not obligated to consider the interests of the company, the holders of our equity or debt securities or the holders of Fannie Mae MBS unless specifically directed to do so by the conservator. We describe the rights and powers of the conservator, key provisions ofour agreements with the U.S. Department of the Treasury (“Treasury”), and theirimpact on shareholders in our Annual Report on Form 10-K for the year ended December 31, 2015 (“2015 Form 10-K”) in “Business—Conservatorship and Treasury Agreements.”

You should read this Management’s Discussion and Analysis of FinancialCondition and Results of Operations (“MD&A”) in conjunction with our unaudited condensed consolidated financial statements and related notes in this report and the more detailed information in our 2015 Form 10-K.

This report contains forward-looking statements that are based on management’s current expectations and are subject to significant uncertainties and changes in circumstances. Please review “Forward-Looking Statements” for more information on theforward-looking statements in this report.Our actual results may differ materially from those reflected in our forward-looking statements due to a variety of factors including, but not limited to, those discussed in “Risk Factors” and elsewhere in this report and in our 2015 Form 10-K.

You can find a “Glossary of Terms Used in ThisReport” in the “MD&A” of our 2015 Form 10-K.

INTRODUCTION

Fannie Mae is a government-sponsored enterprise (“GSE”) that was chartered by Congress in 1938. We serve an essential role in the functioning of the U.S. housing market and are investing in improvements to the U.S. housing finance system. Our public mission is to support liquidity and stability in the secondary mortgage market, where existing mortgage-related assets are purchased and sold, and to increase the supply of affordable housing. Our charter does not permit us to originate loans or lend money directly to consumers in the primary mortgage market.

Fannie Mae provides reliable, large-scale access to affordable mortgage credit and indirectly enables families to buy, refinance or rent homes. We securitize mortgage loans originated by lenders into Fannie Mae mortgage-backed securities that we guarantee, which we refer to as Fannie Mae MBS. One of our key functions is to evaluate, price and manage the credit risk on the loans and securities that we guarantee. We also purchase mortgage loans and mortgage-related securities, primarily for securitization and sale at a later date. We use the term “acquire” in this report to refer to both our securitizations and our purchases of mortgage-related assets. We obtain funds to support our business activities by issuing a variety of debt securities in the domestic and international capital markets, which attracts global capital to the United States housing market.

We remain in conservatorship and our conservatorship has no specified termination date. We do not know when or how the conservatorship will terminate, what further changes to our business will be made during or following conservatorship, what form we will have and what ownership interest, if any, our current common and preferred stockholders will hold in us after the conservatorship is terminated or whether we will continue to exist following conservatorship. In addition, as a result of our agreements with Treasury and dividend directives from our conservator, we are not permitted to retain our net worth (other than a limited amount that will decrease to zero by 2018), rebuild our capital position or pay dividends or other distributions to stockholders other than Treasury. Our senior preferred stock purchase agreement with Treasury also includes covenants that significantly restrict our business activities. Congress and the Obama Administration continue to consider options for reform of the housing finance system, including the GSEs. We cannot predict the prospects for the enactment, timing or final content of housing finance reform legislation or actions the Administration or FHFA may take with respect to housing finance reform. The conservatorship, the uncertainty of our future, limitations on executive and employee compensation, and negative publicity concerning the GSEs have had and are likely to continue to have an adverse effect on our ability to retain and recruit well-qualified executives and other employees. We provide additional information on the conservatorship, the provisions of our agreements with Treasury, and their impact on our business in our 2015 Form 10-K in “Business—Conservatorship and Treasury Agreements” and “Risk Factors.” We discuss the uncertainty of our future in

1

“Executive Summary—Outlook” and “Risk Factors” in this report. We discuss proposals for housing finance reform that could materially affect our business in our 2015 Form 10-K in “Business—Housing Finance Reform.”

Although Treasury owns our senior preferred stock and a warrant to purchase 79.9% of our common stock, and has made a commitment under a senior preferred stock purchase agreement to provide us with funds to maintain a positive net worth under specified conditions, the U.S. government does not guarantee our securities or other obligations.

Our common stock is traded in the over-the-counter market and quoted on the OTC Bulletin Board under the symbol “FNMA.” Our debt securities are actively traded in the over-the-counter market.

EXECUTIVE SUMMARY

Overview

We reported net income of $3.2 billion for the third quarter of 2016, compared with net income of $2.0 billion for the third quarter of 2015. See “Summary of Our Financial Performance” below for an overview of our financial performance for the third quarter and first nine months of 2016, compared with the third quarter and first nine months of 2015. We expect to remain profitable on an annual basis for the foreseeable future; however, certain factors, such as changes in interest rates or home prices, could result in significant volatility in our financial results from quarter to quarter or year to year. For more information regarding our expectations for our future financial performance, see “Outlook” below.

With our expected December 2016 dividend payment to Treasury, we will have paid a total of $154.4 billion in dividends to Treasury on our senior preferred stock. The aggregate amount of draws we have received from Treasury to date under the senior preferred stock purchase agreement is $116.1 billion. Under the terms of the senior preferred stock purchase agreement, dividend payments do not offset prior Treasury draws. For more information regarding our dividend payments to Treasury, see “Treasury Senior Preferred Stock Purchase Agreement” below.

Our Strategy and Business Objectives

Our vision is to be America’s most valued housing partner and to provide liquidity, access to credit and affordability in all U.S. housing markets at all times, while effectively managing and reducing risk to our business, taxpayers and the housing finance system. In support of this vision, we are focused on:

• advancing a sustainable and reliable business model that reduces risk to the housing finance system and taxpayers;

• providing reliable, large-scale access to affordable mortgage credit for qualified borrowers and helping struggling homeowners; and

• serving customer needs and improving our business efficiency.

Advancing a sustainable and reliable business model that reduces risk to the housing finance system and taxpayers

We have significantly changed our business model since we entered conservatorship in 2008 and our business continues to evolve. We have strengthened our underwriting and eligibility standards, we are moving from a portfolio-focused business to a guaranty-focused business and we are transferring an increasing portion of the credit risk on our guaranty book of business. These changes are transforming our business model and reducing certain risks of our business as compared with our business prior to entering conservatorship.

Stronger underwriting and eligibility standards. Beginning in 2008, we made changes to strengthen our underwriting and eligibility standards that have improved the credit quality of our single-family guaranty book of business and contributed to improvement in our credit performance. See “Single-Family Guaranty Book of Business” below for information on the credit performance of the mortgage loans in our single-family guaranty book of business and on our recent single-family acquisitions.

Moving from a portfolio-focused business to a guaranty-focused business. In recent years, an increasing portion of our net interest income has been derived from the guaranty fees we receive for managing the credit risk on loans underlying our Fannie Mae MBS, rather than from interest income on our retained mortgage portfolio assets. This shift has been driven by both the impact of guaranty fee increases implemented in 2012 and the reduction of our retained mortgage portfolio in accordance with the requirements of our senior preferred stock purchase agreement with Treasury and direction from FHFA. Our retained mortgage portfolio refers to the mortgage-related assets we own (which excludes the portion of assets held by consolidated MBS trusts that back mortgage-related securities owned by third parties). In the first nine months of 2016, more

2

than two-thirds of our net interest income was derived from our guaranty business. As described in more detail in “Outlook—Revenues” below, we expect that guaranty fees will continue to account for an increasing portion of our net interest income.

Transferring a portion of the mortgage credit risk on our single-family book of business. In late 2013, we began entering into credit risk transfer transactions with the goal of transferring, to the extent economically sensible, a portion of the mortgage credit risk on some of the recently-acquired loans in our single-family book of business in order to reduce the economic risk to us and to taxpayers of future borrower defaults.As of September 30, 2016, $594 billion in outstanding unpaid principal balance of our single-family loans, or approximately 21% of the loans in our single-family conventional guaranty book of business measured by unpaid principal balance, were included in a reference pool for a Connecticut Avenue Securities^TM (“CAS”) or a Credit Insurance Risk Transfer^TM (“CIRT^TM”) transaction. We intend to continue to engage in credit risk transfer transactions on an ongoing basis, subject to market conditions. Over time, we expect that a larger portion of our single-family conventional guaranty book of business will be covered by credit risk transfer transactions. For further discussion of our credit risk transfer transactions, see “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management—Transfer of Mortgage Credit Risk—Credit Risk-Sharing Transactions.”

Our business also continues to evolve as a result of our many other efforts to build a safer and sustainable housing finance system and to pursue the strategic goals identified by our conservator, and we continue to invest significant resources towards these goals. See “Business—Executive Summary—Helping to Build a Sustainable Housing Finance System” in our 2015 Form 10-K for a discussion of these efforts and FHFA’s strategic goals for our conservatorship, including a description of some of the actions we are taking pursuant to the mandates of FHFA’s conservatorship scorecards in order to build the policies and infrastructure for a sustainable housing finance system. For more information on FHFA’s 2016 conservatorship scorecard objectives, see our Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on December 17, 2015.

Providing reliable, large-scale access to affordable mortgage credit for qualified borrowers and helping struggling homeowners

We continued to provide reliable, large-scale access to affordable mortgage credit to the U.S. housing market in the third quarter of 2016 and remained a leading source of liquidity in the single-family and multifamily markets. We also continued to help struggling homeowners. In the third quarter of 2016, we provided approximately 26,500 loan workouts to help homeowners stay in their homes or otherwise avoid foreclosure. We discuss our activities to support the housing and mortgage markets in “Contributions to the Housing and Mortgage Markets” below.

Serving customer needs and improving our business efficiency

We are continuing our initiatives to better serve our customers’ needs and improve our business efficiency in 2016. These initiatives include continuing to revise and clarify lenders’ representation and warranty obligations, implementing innovative new and enhanced tools that deliver greater value and certainty to lenders, simplifying our business processes, and updating our infrastructure. We discuss these initiatives in “Serving Customer Needs and Improving Our Business Efficiency” below and in our 2015 Form 10-K in “Business—Executive Summary.”

Summary of Our Financial Performance

Comprehensive Income

Quarterly Results

We recognized comprehensive income of $3.0 billion in the third quarter of 2016, consisting of net income of $3.2 billion and other comprehensive loss of $207 million. In comparison, we recognized comprehensive income of $2.2 billion in the third quarter of 2015, consisting of net income of $2.0 billion and other comprehensive income of $253 million. The increase in our net income in the third quarter of 2016 compared with the third quarter of 2015 was primarily driven by a decrease in fair value losses, partially offset by a decrease in credit-related income and lower net revenues.

We recognized fair value losses of $491 million in the third quarter of 2016 compared with fair value losses of $2.6 billion in the third quarter of 2015. Fair value losses in the third quarter of 2016 were primarily due to losses on CAS debt carried at fair value primarily due to tightening spreads between CAS debt yields and LIBOR during the period. Fair value losses in the third quarter of 2015 were primarily driven by losses on our risk management derivatives resulting from declines in longer-term swap rates during the period.

We recognized credit-related income of $563 million in the third quarter of 2016 compared with credit-related income of $1.1 billion in the third quarter of 2015. Credit-related income in the third quarter of 2016 was driven by a $673 million benefit for credit losses during the quarter, which was primarily attributable to an increase in home prices, including distressed property

3

valuations. Higher home prices decrease the likelihood that loans will default and reduce the amount of credit loss on loans that do default, which impacts our estimate of losses and ultimately reduces our total loss reserves and provision for credit losses. Credit-related income in the third quarter of 2015 was driven by a benefit for credit losses that was primarily attributable to an increase in home prices as well as a decrease in interest rates during the period. As interest rates decline, we expect an increase in future prepayments on single-family individually impaired loans, including modified loans. Higher expected prepayments shorten the expected lives of modified loans, which decreases the impairment relating to concessions provided on these loans and results in a decrease in our provision for credit losses.

Net revenues, which consist of net interest income and fee and other income, were $5.6 billion in the third quarter of 2016 and $5.8 billion in the third quarter of 2015. We recognized net interest income of $5.4 billion in the third quarter of 2016 and $5.6 billion in the third quarter of 2015. The decline in net interest income was primarily due to a decline in the average balance of our retained mortgage portfolio, partially offset by an increase in guaranty fee revenue.

Year-to-Date Results

We recognized comprehensive income of $6.8 billion in the first nine months of 2016, consisting of net income of $7.3 billion and other comprehensive loss of $484 million. In comparison, we recognized comprehensive income of $8.4 billion in the first nine months of 2015, consisting of net income of $8.5 billion and other comprehensive loss of $120 million. The decrease in our net income was primarily driven by an increase in fair value losses and a decrease in net revenues, partially offset by a shift to credit-related income from credit-related expense.

Fair value losses of $5.0 billion in the first nine months of 2016 and $1.9 billion in the first nine months of 2015 were primarily driven by losses on our risk management derivatives resulting from declines in longer-term swap rates during the periods.

Net revenues were $16.0 billion in the first nine months of 2016 and $17.5 billion in the first nine months of 2015. We recognized net interest income of $15.5 billion in the first nine months of 2016 and $16.3 billion in the first nine months of 2015. The decline in net interest income was primarily a result of the same factors that affected our results for the third quarter of 2016, as described above.

We recognized credit-related income of $3.0 billion in the first nine months of 2016. In comparison, we recognized credit-related expense of $102 million in the first nine months of 2015. Credit-related income in the first nine months of 2016 was primarily attributable to a $3.5 billion benefit for credit losses during the period, which was primarily driven by an increase in home prices, including distressed property valuations, and a decrease in interest rates. Credit-related expense in the first nine months of 2015 was comprised of foreclosed property expense, partially offset by a benefit for credit losses. Foreclosed property expense in the first nine months of 2015 was primarily driven by property preservation costs, which include property tax and insurance expenses relating to our single-family foreclosed properties. The benefit for credit losses in the first nine months of 2015 was primarily driven by higher home prices. This was partially offset by the impact from the redesignation of certain nonperforming single-family loans from held for investment (“HFI”) to held for sale (“HFS”). These loans were adjusted to the lower of cost or fair value, which reduced our benefit for credit losses. Additionally, interest rates increased during the first nine months of 2015, which also partially offset our benefit for credit losses.

We expect volatility from period to period in our financial results from a number of factors, particularly changes in market conditions that result in fluctuations in the estimated fair value of the financial instruments that we mark to market through our earnings. These instruments include derivatives and certain securities. The estimated fair value of our derivatives and securities may fluctuate substantially from period to period because of changes in interest rates, the yield curve, mortgage and credit spreads, and implied volatility, as well as activity related to these financial instruments. We use derivatives to manage the interest rate risk exposure of our net portfolio, which consists of our retained mortgage portfolio, cash and other investments portfolio, and outstanding debt of Fannie Mae. Some of these financial instruments in our net portfolio are not recorded at fair value in our condensed consolidated financial statements, and as a result we may experience accounting gains or losses due to changes in interest rates or other market conditions that may not be indicative of the economic interest rate risk exposure of our net portfolio. See “Risk Management—Market Risk Management, Including Interest Rate Risk Management” for more information. In addition, our credit-related income or expense can vary substantially from period to period based on factors such as changes in actual and expected home prices, borrower payment behavior, the types and volume of our loss mitigation activities, the volumes of foreclosures completed, redesignations of loans from HFI to HFS, and fluctuations in interest rates.

See “Consolidated Results of Operations” for more information on our results.

Net Worth

Our net worth increased to $4.2 billion as of September 30, 2016 from $4.1 billion as of December 31, 2015, primarily due to our comprehensive income of $6.8 billion, offset by our payments to Treasury of $6.7 billion in senior preferred stock dividends during the first nine months of 2016. Our expected dividend payment of $3.0 billion for the fourth quarter of 2016 is calculated based on our net worth of $4.2 billion as of September 30, 2016 less the applicable capital reserve amount of $1.2 billion.

Single-Family Guaranty Book of Business

Credit Performance

We continued to acquire loans with strong credit profiles and to execute on our strategies for reducing credit losses in the third quarter of 2016, such as helping eligible Fannie Mae borrowers with high loan-to-value (“LTV”) ratio loans refinance into more sustainable loans through the Administration’s Home Affordable Refinance Program^® (“HARP^®”), offering borrowers loan modifications that can significantly reduce their monthly payments, pursuing foreclosure alternatives and managing our real estate owned (“REO”) inventory to appropriately manage costs and maximize sales proceeds. As we work to reduce credit losses, we also seek to assist struggling homeowners, help stabilize communities and support the housing market.

Table 1 presents information about the credit performance of mortgage loans in our single-family guaranty book of business and our workouts. The term “workouts” refers to both home retention solutions (loan modifications and other solutions that enable a borrower to stay in his or her home) and foreclosure alternatives (short sales and deeds-in-lieu of foreclosure). The workout information in Table 1 does not reflect repayment plans and forbearances that have been initiated but not completed, nor does it reflect trial modifications that have not become permanent.

⁽⁶⁾  Calculated as the amount of sale proceeds received on disposition of REO properties during the respective period, excluding those subject to repurchase requests made to our sellers or servicers, divided by the aggregate unpaid principal balance of the related loans at the time of foreclosure. Net sales price represents the contract sales price less selling costs for the property and other charges paid by the seller at closing.

⁽⁷⁾  Calculated as the amount of sale proceeds received on properties sold in short sale transactions during the respective periods divided by the aggregate unpaid principal balance of the related loans. Net sales price represents the contract sales price less the selling costs for the property and other charges paid by the seller at the closing, including borrower relocation incentive payments and subordinate lien(s) negotiated payoffs.

⁽⁸⁾  Consists of (a) modifications, which do not include trial modifications, loans to certain borrowers who have received bankruptcy relief that are classified as troubled debt restructurings (“TDRs”), or repayment plans or forbearances that have been initiated but not completed and (b) repayment plans and forbearances completed. See “Table 30: Statistics on Single-Family Loan Workouts” in “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management—Problem Loan Management—Loan Workout Metrics” for additional information on our various types of loan workouts.

⁽⁹⁾  Calculated based on annualized problem loan workouts during the period as a percentage of the average balance of delinquent loans in our single-family guaranty book of business.

Beginning in 2008, we took actions to significantly strengthen our underwriting and eligibility standards to promote sustainable homeownership and stability in the housing market. These actions have improved the credit quality of our book of business and contributed to improvement in our credit performance. For information on the credit risk profile of our single-family guaranty book of business, see “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management,” including “Table 27: Risk Characteristics of Single-Family Conventional Business Volume and Guaranty Book of Business.”

Our single-family serious delinquency rate has decreased each quarter since the first quarter of 2010, and was 1.24% as of September 30, 2016, compared with 1.55% as of December 31, 2015. We continue to experience disproportionately higher serious delinquency rates and credit losses from single-family loans originated in 2005 through 2008 than from loans originated in other years. Single-family loans originated in 2005 through 2008 constituted 9% of our single-family book of business as of September 30, 2016, but constituted 53% of our seriously delinquent single-family loans as of September 30, 2016 and drove 60% of our single-family credit losses in the third quarter of 2016. For information on the credit performance of our single-family book of business based on loan vintage, see “Table 11: Credit Loss Concentration Analysis” in “Consolidated Results of Operations—Credit-Related Income (Expense)—Credit Loss Performance Metrics” and “Table 29: Single-Family Conventional Seriously Delinquent Loan Concentration Analysis” in “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management.” For information on certain credit characteristics of our single-family book of business based on the period in which we acquired the loans, see “Table 24: Selected Credit Characteristics of Single-Family Conventional Guaranty Book of Business, by Acquisition Period” in “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management.”

We provide additional information on our credit-related income or expense and our credit losses in “Consolidated Results of Operations—Credit-Related Income (Expense).” We provide more information on the credit performance of mortgage loans in our single-family book of business and our efforts to reduce our credit losses in “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management.” See also “Risk Factors” in our 2015 Form 10-K, where we describe factors that may increase our credit-related expense and credit losses, as well as factors that may adversely affect the success of our efforts to reduce our credit losses.

⁽¹⁾  Excludes the impact of a 10 basis point guaranty fee increase implemented in 2012 pursuant to the Temporary Payroll Tax Cut Continuation Act of 2011 (the “TCCA”). This TCCA-related fee is unrelated to our pricing strategy, as the incremental revenue from this fee is remitted to Treasury and not retained by us. Average charged guaranty fee is calculated based on the average contractual fee rate, net of TCCA fee, for our single-family guaranty arrangements entered into during the period plus the recognition of any upfront cash payments ratably over an estimated average life, expressed in basis points.

⁽²⁾  Calculated based on unpaid principal balance of single-family loans for each category at time of acquisition.

⁽³⁾  The original LTV ratio generally is based on the original unpaid principal balance of the loan divided by the appraised property value reported to us at the time of acquisition of the loan. Excludes loans for which this information is not readily available.

⁽⁴⁾  We purchase loans with original LTV ratios above 80% as part of our mission to serve the primary mortgage market and provide liquidity to the housing finance system. Except as permitted under HARP, our charter generally requires primary mortgage insurance or other credit enhancement for loans that we acquire that have an LTV ratio over 80%.

The average charged guaranty fee on our newly-acquired single family loans declined in the first nine months of 2016 compared with the first nine months of 2015, due to both: (1) changes in the contractual guaranty fee rates we charged for some loan types in response to market conditions; and (2) a decrease in the loan level price adjustments we charged on our acquisitions driven by improved credit risk metrics on these acquisitions as compared with our acquisitions in the first nine

7

months of 2015. Loan level price adjustments are one-time cash fees that we charge at the time we acquire a loan based on the loan’s features.

In July 2016, FHFA advised us that it had established minimum base guaranty fees that generally apply to our acquisitions of 30-year and 15-year fixed-rate loans in lender swap transactions. These new minimum base guaranty fees were implemented in November 2016 and may affect our average charged guaranty fee on newly-acquired single family loans in future periods. For further discussion of FHFA’s establishment of minimum base guaranty fees, see “MD&A—Legislative and Regulatory Developments—FHFA Developments—Establishment of Minimum Base Guaranty Fees” in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2016 (“Second Quarter 2016 Form 10-Q”).

The single-family loans we acquired in the third quarter of 2016 continued to have a strong credit profile, with a weighted average original LTV ratio of 74% and a weighted average FICO credit score of 752. For more information on the credit risk profile of our single-family conventional loan acquisitions in the third quarter and first nine months of 2016, see “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management,” including “Table 27: Risk Characteristics of Single-Family Conventional Business Volume and Guaranty Book of Business” in that section.

Whether the loans we acquire in the future will exhibit an overall credit profile and performance similar to our more recent acquisitions will depend on a number of factors, including: our future guaranty fee pricing and any impact of that pricing on the volume and mix of loans we acquire; our future eligibility standards and those of mortgage insurers, the Federal Housing Administration (“FHA”) and the Department of Veterans Affairs (“VA”); the percentage of loan originations representing refinancings; changes in interest rates; our future objectives and activities in support of those objectives, including actions we may take to reach additional underserved creditworthy borrowers; government policy; market and competitive conditions; and the volume and characteristics of HARP and high LTV refinance loans we acquire in the future. In addition, if our lender customers retain more of the higher-quality loans they originate, it could negatively affect the credit risk profile of our new single-family acquisitions.

Providing Access to Credit Opportunities for Creditworthy Borrowers

We are continuing our efforts to increase access to mortgage credit for creditworthy borrowers, consistent with the full extent of our applicable credit requirements and risk management practices. As part of these efforts, in 2014 we changed our eligibility requirements to increase our maximum LTV ratio from 95% to 97% for loans meeting certain criteria, and in 2015 we announced an improved affordable lending product, HomeReady^®, which is designed for creditworthy borrowers with lower and moderate incomes and provides expanded eligibility for financing homes in designated low-income communities. We began acquiring loans under our revised eligibility criteria in December 2014 and under HomeReady in December 2015. See “Business—Executive Summary—Single-Family Guaranty Book of Business—Providing Access to Credit Opportunities for Creditworthy Borrowers” in our 2015 Form 10-K for more information regarding these loans, including a discussion of their eligibility requirements, the number of these loans acquired in 2015 and our expectations regarding our future acquisitions of these loans.

We continue to seek new ways to responsibly expand access to mortgage credit. FHFA’s 2016 conservatorship scorecard specifies that in 2016 we should continue to assess impediments to credit access and develop recommendations to address these barriers. To the extent we are able to encourage lenders to increase access to mortgage credit, we may acquire a greater number of single-family loans with higher risk characteristics than we acquired in recent periods; however, we expect our single-family acquisitions will continue to have a strong overall credit risk profile given our current underwriting and eligibility standards and product design. We actively monitor the credit risk profile and credit performance of our single-family loan acquisitions, in conjunction with housing market and economic conditions, to determine if our pricing, eligibility and underwriting criteria accurately reflect the risks associated with loans we acquire or guarantee.

Contributions to the Housing and Mortgage Markets

Liquidity and Support Activities

As a leading provider of residential mortgage credit in the United States, we indirectly enable families to buy, refinance or rent homes. During the third quarter of 2016, we continued to provide critical liquidity and support to the U.S. mortgage market in a number of important ways:

8

• We serve as a stable source of liquidity for purchases of homes and financing of multifamily rental housing, as well as for refinancing existing mortgages. We provided approximately $184 billion in liquidity to the mortgage market in the third quarter of 2016 through our purchases of loans and guarantees of loans and securities. This liquidity enabled borrowers to complete approximately 375,000 mortgage refinancings and approximately 338,000 home purchases, and provided financing for approximately 240,000 units of multifamily housing.

• Our role in the market enables qualified borrowers to have reliable access to affordable mortgage credit, including a variety of conforming mortgage products such as the prepayable 30-year fixed-rate mortgage that protects homeowners from fluctuations in interest rates.

• We provided approximately 26,500 loan workouts in the third quarter of 2016 to help homeowners stay in their homes or otherwise avoid foreclosure. Our loan workout efforts have helped to stabilize neighborhoods, home prices and the housing market.

• We helped borrowers refinance loans, including through our Refi Plus™ initiative, which offers additional refinancing flexibility to eligible borrowers who are current on their loans, whose loans are owned or guaranteed by us and who meet certain additional criteria. We acquired approximately 35,000 Refi Plus loans in the third quarter of 2016. Refinancings delivered to us through Refi Plus in the third quarter of 2016 reduced borrowers’ monthly mortgage payments by an average of $219.

• We support affordability in the multifamily rental market. Approximately 90% of the multifamily units we financed in the third quarter of 2016 were affordable to families earning at or below 120% of the median income in their area, providing support for both workforce housing and affordable housing.

• In addition to purchasing and guaranteeing loans, we provide funds to the mortgage market through short-term financing and other activities. These activities are described in our 2015 Form 10-K in “Business—Business Segments—Capital Markets.”

2016 Market Share

We were one of the largest issuers of mortgage-related securities in the secondary market during the third quarter of 2016. Our estimated market share of new single-family mortgage-related securities issuances was 38% in both the third quarter and second quarter of 2016, compared with 36% in the third quarter of 2015.

Historically, Fannie Mae MBS has had a trading advantage over comparable Freddie Mac Participation Certificates (“Freddie Mac PCs”); however, recently, there has no longer been a significant price difference between Fannie Mae MBS and comparable Freddie Mac PCs. We believe a significant driver of the recent convergence in price between Fannie Mae MBS and comparable Freddie Mac PCs is the market’s expectation of a single GSE mortgage-backed security in the future. Despite this price convergence, our market share of new single-family mortgage-related securities issuances remained unchanged in the third quarter of 2016 as compared with the prior quarter. If our market share declines in the future due to this trend or other factors, it could adversely affect our financial results.

We remained a continuous source of liquidity in the multifamily market in the third quarter and first nine months of 2016. We owned or guaranteed approximately 19% of the outstanding debt on multifamily properties as of June 30, 2016 (the latest date for which information is available).

Serving Customer Needs and Improving Our Business Efficiency

We are engaged in various initiatives to better serve our customers’ needs and improve our business efficiency. We are committed to providing our lender partners with the products, services and tools they need to serve the market more effectively and efficiently. To further this commitment, we are focused on continuing to revise and clarify lenders’ representation and warranty obligations, implementing innovative new and enhanced tools that deliver greater value and certainty to lenders, and making our customers’ interactions with us simpler and more efficient.

Continuing to revise and clarify lenders’ representation and warranty obligations. We have taken several actions in recent years to improve our representation and warranty framework and revise and clarify lenders’ representation and warranty obligations to us. These actions have significantly reduced uncertainty surrounding lenders’ repurchase risk relating to loans they deliver to us, and our intention is that these actions will encourage lenders to safely expand their lending to a wider range of qualified borrowers. As of September 30, 2016, over 2.8 million loans in our book of business had obtained relief from repurchases for breaches of certain representations and warranties. We continue to work on new ways to reduce or clarify lenders’ repurchase risk. For example, we are leveraging the verification tools we offer through our Desktop Underwriter^® automated underwriting system to expand the representation and warranty relief we provide to lenders. In October 2016, we announced that we will provide lenders with representation and warranty relief with respect to borrower

9

data that has been validated by Desktop Underwriter and with respect to property value where the appraisal has received a qualifying risk score in our Collateral Underwriter^® appraisal review tool. See “Business—Executive Summary—Serving Customer Needs and Improving Our Business Efficiency” in our 2015 Form 10-K and “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management” in both our 2015 Form 10-K and this report for further discussion of changes to our representation and warranty framework and actions we have taken to reduce and clarify lenders’ repurchase risk.

Implementing innovative new and enhanced tools that deliver greater value and certainty to lenders. As described in “Business—Executive Summary—Serving Customer Needs and Improving Our Business Efficiency” in our 2015 Form 10-K, in 2015 we implemented a number of changes designed to help our customers originate mortgages with increased certainty, efficiency and lower costs. We continue to focus on improving our business to provide value to customers. For example:

• In September 2016, we incorporated trended credit data into Desktop Underwriter. Trended credit data refers to additional historical information on a borrower’s use of revolving credit accounts, including the balance, scheduled payments and actual payments made on these accounts. Incorporating trended credit data is expected to improve the accuracy of Desktop Underwriter’s credit risk assessment and benefit borrowers who regularly pay down their revolving debt. The September 2016 update to Desktop Underwriter also added the ability to underwrite loans where the borrower does not have a credit score, automating what was previously a manual process for lenders.

• In October 2016, we began offering third-party validation of borrower income data through Desktop Underwriter. We plan to expand this third-party validation service to borrower asset and employment data in December 2016.

We expect these enhancements to Desktop Underwriter will help our lender customers originate mortgages with increased certainty, efficiency and lower costs, and also help increase access to credit for creditworthy borrowers.

Making our customers’ interactions with us simpler and more efficient. We are also engaged in a multi-year effort to improve our business efficiency and agility through simplification of our business processes and enhancements to our infrastructure. Many of these improvements are also designed to enhance our customers’ experience when doing business with us, including making our customers’ interactions with us simpler and more efficient. These efforts include replacing some of our systems with simpler, more automated infrastructure that will enable us to more efficiently process transactions and manage our book of business, as well as to better adapt to industry and regulatory changes in the future. We are also implementing infrastructure improvements to support the integration of our business with the common securitization platform and our ability to issue a single security. For information about the common securitization platform and single security, see “Business—Housing Finance Reform—Conservator Developments” in our 2015 Form 10-K and “MD&A—Legislative and Regulatory Developments—FHFA Developments—Common Securitization Platform and Single Security” in our Second Quarter 2016 Form 10-Q.

Treasury Senior Preferred Stock Purchase Agreement

From 2009 through the first quarter of 2012, we received a total of $116.1 billion from Treasury under the senior preferred stock purchase agreement. This funding provided us with the capital and liquidity needed to fulfill our mission of providing liquidity and support to the nation’s housing finance markets and to avoid triggering mandatory receivership under the Federal Housing Enterprises Financial Safety and Soundness Act of 1992, as amended by the Federal Housing Finance Regulatory Reform Act of 2008 (together, the “GSE Act”). In addition, a portion of the $116.1 billion we received from Treasury was drawn to pay dividends to Treasury because, prior to 2013, our dividend payments on the senior preferred stock accrued at an annual rate of 10%, and we were directed by our conservator to pay these dividends to Treasury each quarter even when we did not have sufficient income to pay the dividend. We have not received funds from Treasury under the agreement since the first quarter of 2012.

From 2008 through the third quarter of 2016, we paid a total of $151.4 billion in dividends to Treasury on the senior preferred stock. Under the terms of the senior preferred stock purchase agreement, dividend payments do not offset prior Treasury draws, and we are not permitted to pay down draws we have made under the agreement except in limited circumstances. Accordingly, the current aggregate liquidation preference of the senior preferred stock is $117.1 billion, due to the initial $1.0 billion liquidation preference of the senior preferred stock (for which we did not receive cash proceeds) and the $116.1 billion we have drawn from Treasury.

The Director of FHFA has directed us to make dividend payments on the senior preferred stock on a quarterly basis. We expect to pay Treasury a senior preferred stock dividend of $3.0 billion by December 31, 2016 for the fourth quarter of 2016.

We expect to retain only a limited amount of any future net worth because we are required by the dividend provisions of the senior preferred stock and quarterly directives from our conservator to pay Treasury each quarter any dividends declared

10

consisting of the amount, if any, by which our net worth as of the end of the immediately preceding fiscal quarter exceeds an applicable capital reserve amount. This capital reserve amount is $1.2 billion for each quarter of 2016, will decrease to $600 million in 2017 and will decrease to zero in 2018. Those dividend payment provisions are referred to as “net worth sweep” dividend provisions.

Although we expect to remain profitable on an annual basis for the foreseeable future, due to our expectation of continued declining capital and the potential for significant volatility in our financial results, we could experience a net worth deficit in a future quarter, particularly as our capital reserve amount approaches or reaches zero. If that were to occur, we would be required to draw additional funds from Treasury under the senior preferred stock purchase agreement in order to avoid being placed into receivership. As of the date of this filing, the maximum amount of remaining funding under the agreement is $117.6 billion. If we were to draw additional funds from Treasury under the agreement in a future period, the amount of remaining funding under the agreement would be reduced by the amount of our draw. Dividend payments we make to Treasury do not restore or increase the amount of funding available to us under the agreement. See “Risk Factors” in our 2015 Form 10-K for a discussion of the risks associated with our limited and declining capital.

As described in “Legal Proceedings” and “Note 16, Commitments and Contingencies,” several lawsuits have been filed by preferred and common stockholders of Fannie Mae and Freddie Mac against one or more of the United States, Treasury and FHFA challenging actions taken by the defendants relating to the senior preferred stock purchase agreements and the conservatorships of Fannie Mae and Freddie Mac, including challenges to the net worth sweep dividend provisions of the senior preferred stock. We are also a party to some of those lawsuits. We cannot predict the course or the outcome of these lawsuits, or the actions the U.S. government (including Treasury or FHFA) may take in response to any ruling or finding in any of these lawsuits.

Housing and Mortgage Market and Economic Conditions

According to the U.S. Bureau of Economic Analysis advance estimate, the inflation-adjusted U.S. gross domestic product, or GDP, rose by 2.9% on an annualized basis in the third quarter of 2016, compared with an increase of 1.4% in the second quarter of 2016. The overall economy gained an estimated 575,000 non-farm jobs in the third quarter of 2016. According to the U.S. Bureau of Labor Statistics, over the 12 months ending in September 2016, the economy created an estimated 2.4 million non-farm jobs. The unemployment rate was 5.0% in September 2016, compared with 4.9% in June 2016.

According to the Federal Reserve, total U.S. residential mortgage debt outstanding, which includes $10.1 trillion of single-family debt outstanding, was estimated to be approximately $11.2 trillion as of June 30, 2016 (the latest date for which information is available) and $11.1 trillion as of March 31, 2016.

Housing sales were mixed in the third quarter of 2016 as compared with the second quarter of 2016. Total existing home sales averaged 5.4 million units annualized in the third quarter of 2016, a 2.2% decrease from the second quarter of 2016, according to data from the National Association of REALTORS^®. Sales of foreclosed homes and preforeclosure, or “short,” sales (together, “distressed sales”) accounted for 4% of existing home sales in September 2016, compared with 6% in June 2016 and 7% in September 2015. According to the U.S. Census Bureau, new single-family home sales increased during the third quarter of 2016, averaging an annualized rate of 599,000 units, a 6.1% gain from the second quarter of 2016.

The number of months’ supply, or the inventory/sales ratio, of available existing homes remained unchanged in the third quarter of 2016, while the supply of available new homes decreased during the quarter. According to the National Association of REALTORS, the months’ supply of existing unsold homes was 4.5 months as of September 30, 2016 and June 30, 2016. According to the U.S. Census Bureau, the months’ supply of new single-family unsold homes was 4.8 months as of September 30, 2016, compared with 5.2 months as of June 30, 2016.

The overall mortgage market serious delinquency rate fell to 3.1% as of June 30, 2016 (the latest date for which information is available), according to the Mortgage Bankers Association’s National Delinquency Survey, its lowest level since the third quarter of 2007, compared with 3.3% as of March 31, 2016. We provide information about Fannie Mae’s serious delinquency rate, which decreased in the third quarter of 2016, in “Single-Family Guaranty Book of Business—Credit Performance.”

Based on our home price index, we estimate that home prices on a national basis increased by 1.5% in the third quarter of 2016 and by 5.7% in the first nine months of 2016, following increases of 4.7% in 2015, 4.3% in 2014 and 7.8% in 2013. Despite the recent increases in home prices, we estimate that, through September 30, 2016, home prices on a national basis remained 1.1% below their peak in the third quarter of 2006. Our home price estimates are based on preliminary data and are subject to change as additional data become available.

Thirty-year fixed-rate mortgage rates ended the quarter at 3.42% for the week of September 29, 2016, down from 3.48% for the week of June 30, 2016, according to Freddie Mac’s Primary Mortgage Market Survey^®.

11

Recently, the prices of Fannie Mae MBS and comparable Freddie Mac PCs in the “To-Be-Announced” (“TBA”) market have converged. For example, Fannie Mae fixed-rate 30-year MBS with a coupon of 3.0% traded 13 basis points higher than the comparable Freddie Mac Gold fixed-rate PC security as of June 30, 2016, compared with only 3 basis points higher as of September 30, 2016.

During the third quarter of 2016, the multifamily sector exhibited stable fundamentals, according to preliminary third-party data, with the estimated national vacancy level remaining at the same level as in the second quarter of 2016, coupled with increasing rent growth. The estimated national multifamily vacancy rate for institutional investment-type apartment properties was 5.0% as of September 30, 2016, the same as of June 30, 2016, but up from 4.8% as of September 30, 2015. National asking rents increased by an estimated 1.0% during the third quarter of 2016, the same percentage as during the second quarter of 2016, but down from the estimated 1.3% increase during the third quarter of 2015. Because estimated multifamily rent growth has outpaced wage growth over the past few years, multifamily rental housing affordability has declined in recent years.

Continued demand for multifamily rental units was reflected in the estimated positive net absorption (that is, the net change in the number of occupied rental units during the time period) of approximately 38,000 units during the third quarter of 2016, according to preliminary data from Reis, Inc. While that is an increase from the approximately 36,000 units absorbed during the second quarter of 2016, the pace of absorption slowed compared with the approximately 41,000 units absorbed during the third quarter of 2015. As a result of the continued demand for multifamily rental units over the past few years, there has been an increase in the amount of new multifamily construction development nationally. Nearly 364,000 new multifamily units are expected to be completed this year. Although the bulk of this new supply is concentrated in a limited number of metropolitan areas, we believe this increase in supply will result in an increase in the national multifamily vacancy rate and a slowdown in rent growth next year.

Outlook

Uncertainty Regarding our Future Status. We expect continued significant uncertainty regarding the future of our company and the housing finance system, including how long the company will continue to exist in its current form, the extent of our role in the market, how long we will be in conservatorship, what form we will have and what ownership interest, if any, our current common and preferred stockholders will hold in us after the conservatorship is terminated, and whether we will continue to exist following conservatorship.

We cannot predict the prospects for the enactment, timing or final content of housing finance reform legislation. See “Business—Housing Finance Reform” in our 2015 Form 10-K for a discussion of proposals for reform of the housing finance system, including the GSEs, that could materially affect our business, including proposals to wind down Fannie Mae and Freddie Mac. See “Risk Factors” in both this report and our 2015 Form 10-K for a discussion of the risks to our business relating to the uncertain future of our company.

Financial Results. We continued to be profitable in the third quarter of 2016, with net income of $3.2 billion. We expect to remain profitable on an annual basis for the foreseeable future; however, certain factors, such as changes in interest rates or home prices, could result in significant volatility in our financial results from quarter to quarter or year to year. Our future financial results also will be affected by a number of other factors, including: our guaranty fee rates; the volume of single-family mortgage originations in the future; the size, composition and quality of our retained mortgage portfolio and guaranty book of business; and economic and housing market conditions. Although we expect to remain profitable on an annual basis for the foreseeable future, due to our expectation of continued declining capital and the potential for significant volatility in our financial results, we could experience a net worth deficit in a future quarter, particularly as our capital reserve amount approaches or reaches zero. See “Treasury Senior Preferred Stock Purchase Agreement” above and “Risk Factors” in our 2015 Form 10-K for more information on, and the risks associated with, our limited and declining capital. In addition, our expectations for our future financial results do not take into account the impact on our business of potential future legislative or regulatory changes, which could have a material impact on our financial results, particularly the enactment of housing finance reform legislation as noted in “Uncertainty Regarding our Future Status” above.

Revenues. We currently have two primary sources of revenues: (1) the guaranty fees we receive for managing the credit risk on loans underlying Fannie Mae MBS held by third parties; and (2) the difference between interest income earned on the assets in our retained mortgage portfolio and the interest expense associated with the debt that funds those assets. In recent years, an increasing portion of our net interest income has been derived from guaranty fees rather than from our retained mortgage portfolio assets, due to the impact of guaranty fee increases implemented in 2012 and the reduction of our retained mortgage portfolio. More than two-thirds of our net interest income for the first nine months of 2016 was derived from the loans underlying our Fannie Mae MBS in consolidated trusts, which primarily generate income through guaranty fees. We expect that guaranty fees will continue to account for an increasing portion of our net interest income.

We expect continued decreases in the size of our retained mortgage portfolio, which will continue to negatively impact our net interest income and net revenues; however, we also expect increases in our guaranty fee revenues will partially offset the negative impact of the decline in our retained mortgage portfolio. We expect our guaranty fee revenues to increase over the next several years, as loans with lower guaranty fees liquidate from our book of business and are replaced with new loans with higher guaranty fees. The extent to which the positive impact of increased guaranty fee revenues will offset the negative impact of the decline in the size of our retained mortgage portfolio will depend on many factors, including: changes to guaranty fee pricing we may make in the future and their impact on our competitive environment and guaranty fee revenues; the size, composition and quality of our guaranty book of business; the life of the loans in our guaranty book of business; the size, composition and quality of our retained mortgage portfolio; economic and housing market conditions, including changes in interest rates; our market share; and legislative and regulatory changes.

Overall Market Conditions. While we expect the single-family serious delinquency rate for the overall mortgage market will continue to decline, we believe the rate of decline will be gradual. We expect the national single-family serious delinquency rate will remain high compared with pre-housing crisis levels because it will take some time for the remaining delinquent loans originated prior to 2009 to work their way through the foreclosure process.

We forecast that total originations in the U.S. single-family mortgage market in 2016 will increase from 2015 levels by approximately 6% from an estimated $1.73 trillion in 2015 to $1.83 trillion in 2016, and that the amount of originations in the U.S. single-family mortgage market that are refinancings will increase from an estimated $808 billion in 2015 to $820 billion in 2016.

Home Prices. Based on our home price index, we estimate that home prices on a national basis increased by 1.5% in the third quarter of 2016 and by 5.7% in the first nine months of 2016. We expect the rate of home price appreciation in 2016 to be slightly higher than the rate in 2015. Future home price changes may be very different from our expectations as a result ofsignificant inherent uncertainty in the current market environment, including uncertainty about the effect of recent and future changes in mortgage rates; actions the federal government has taken and may take with respect to fiscal policies, mortgage finance programs and policies, and housing finance reform; the Federal Reserve’s purchases and sales of mortgage-backed securities; the impact of those actions on and changes generally in unemployment and the general economic and interest rate environment; and the impact on the U.S. economy of global economic and political conditions. We also expect significant regional variation in the timing and rate of home price growth.

Credit Losses. Our credit losses, which include our charge-offs, net of recoveries, reflect our realization of losses on our loans. Our credit losses were $3.0 billion for the first nine months of 2016, down from $8.7 billion for the first nine months of 2015. We expect our credit losses to be lower in 2016 than our 2015 credit losses. See “Consolidated Results of Operations—Credit-Related Income (Expense)—Credit Loss Performance Metrics” for a discussion of our credit losses for the third quarter and first nine months of 2016 and 2015, including the impact on our credit losses for the first nine months of 2015 of our adoption of FHFA’s Advisory Bulletin AB 2012-02, “Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention” (the “Advisory Bulletin”) and a change in our accounting policy for nonaccrual loans, which collectively resulted in $3.6 billion in charge-offs in the first nine months of 2015.

Loss Reserves. Our combined loss reserves were $23.0 billion as of September 30, 2016, down from $28.6 billion as of December 31, 2015. Our loss reserves have declined substantially from their peak and are expected to decline further. For a discussion of the factors that contributed to the decline in our loss reserves in the third quarter and first nine months of 2016, see “Consolidated Results of Operations—Credit-Related Income (Expense)” and “Consolidated Balance Sheet Analysis—Mortgage Loans.”

Factors that Could Cause Actual Results to be Materially Different from Our Estimates and Expectations. We present a number of estimates and expectations in this executive summary regarding our future performance, including estimates and expectations regarding our future financial results and profitability, the level and sources of our future revenues and net interest income, our future dividend payments to Treasury, the credit characteristics of, and the credit risk posed by, our future acquisitions, our future credit risk transfer transactions, our future credit losses and our future loss reserves. We also present a number of estimates and expectations in this executive summary regarding future housing market conditions, including expectations regarding future single-family loan delinquency rates, future mortgage originations, future refinancings, future home prices and future conditions in the multifamily market. These estimates and expectations are forward-looking statements based on our current assumptions regarding numerous factors. Our future estimates of our performance and housing market conditions, as well as the actual results, may differ materially from our current estimates and expectations as a result of: the timing and level of, as well as regional variation in, home price changes; changes in interest rates, including negative interest rates; changes in unemployment rates and other macroeconomic and housing market variables; our future guaranty fee pricing and the impact of that pricing on our guaranty fee revenues and competitive environment; our future serious delinquency rates; our future objectives and activities in support of those objectives, including actions we may take to

13

reach additional underserved creditworthy borrowers; future legislative or regulatory requirements or changes that have a significant impact on our business, such as the enactment of housing finance reform legislation; actions we may be required to take by FHFA, in its role as our conservator or as our regulator, such as changes in the type of business we do or implementation of a single security for Fannie Mae and Freddie Mac; limitations on our business imposed by FHFA, in its role as our conservator or as our regulator; future updates to our models relating to our loss reserves, including the assumptions used by these models; future changes to our accounting policies; significant changes in modification and foreclosure activity; the volume and pace of future nonperforming loan sales and their impact on our results and serious delinquency rates; changes in borrower behavior, such as an increasing number of underwater borrowers who strategically default on their mortgage loans; the effectiveness of our loss mitigation strategies, management of our REO inventory and pursuit of contractual remedies; whether our counterparties meet their obligations in full; resolution or settlement agreements we may enter into with our counterparties; changes in the fiscal and monetary policies of the Federal Reserve, including any change in the Federal Reserve’s policy towards the reinvestment of principal payments of mortgage-backed securities or any future sales of such securities; changes in the fair value of our assets and liabilities; changes in generally accepted accounting principles (“GAAP”); credit availability; global political risks; natural disasters, environmental disasters, terrorist attacks, pandemics or other major disruptive events; information security breaches; and other factors, including those discussed in “Forward-Looking Statements,” “Risk Factors” and elsewhere in this report and in our 2015 Form 10-K. Due to the large size of our guaranty book of business, even small changes in these factors could have a significant impact on our financial results for a particular period.

LEGISLATIVE AND REGULATORY DEVELOPMENTS

The information in this section updates and supplements information regarding legislative and regulatory developments set forth in “Business—Housing Finance Reform” and “Business—Our Charter and Regulation of Our Activities” in our 2015 Form 10-K and in “MD&A—Legislative and Regulatory Developments” in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2016 (“First Quarter 2016 Form 10-Q”) and in our Second Quarter 2016 Form 10-Q. Also see “Risk Factors” in this report and in our 2015 Form 10-K for a discussion of risks relating to legislative and regulatory matters.

Housing Finance Reform

Congress continues to consider housing finance reform that could result in significant changes in our structure and role in the future. As described in “Business—Housing Finance Reform—Legislative Developments” in our 2015 Form 10-K, in the first session of the 114th Congress, which convened in January 2015, several bills were introduced and considered in the Senate and the House of Representatives relating to Fannie Mae, Freddie Mac and the housing finance system, two of which were enacted into law.

We expect Congress to continue to consider legislation relating to the GSEs and housing finance reform, including conducting hearings and considering legislation that would alter the housing finance system or the activities or operations of the GSEs. See “Risk Factors” in this report and our 2015 Form 10-K for a discussion of the risks to our business relating to the uncertain future of our company.

Dodd-Frank Act—FHFA Rule Regarding Stress Testing

Pursuant to an FHFA rule implementing a provision of the Dodd-Frank Wall Street Reform and Consumer Protection Act, we are required to conduct an annual stress test, based on our data as of December 31, using three different scenarios of financial conditions provided by FHFA: baseline, adverse and severely adverse. As required by the rule, we published our most recent stress test results for the severely adverse scenario on our website on August 8, 2016.

2015 Housing Goals Performance

We are subject to housing goals, which establish specified requirements for our mortgage acquisitions relating to affordability or location. Our single-family performance is measured against the lower of benchmarks established by FHFA or goals-qualifying originations in the primary mortgage market. Multifamily goals are established as a number of units to be financed.

In October 2016, after the release of data reported under the Home Mortgage Disclosure Act, FHFA notified us that it had preliminarily determined that we met three of our five single-family housing goals and all of our multifamily housing goals for 2015. For the single-family low-income families home purchase goal, FHFA preliminarily determined that our performance was 23.5% of our 2015 acquisitions of single-family owner-occupied purchase money mortgage loans, which failed to meet the FHFA-established benchmark of 24% or the overall market level of 23.6% for 2015. For the single-family

14

very low-income families home purchase goal, FHFA preliminarily determined that our performance was 5.6% of our 2015 acquisitions of single-family owner-occupied purchase money mortgage loans, which failed to meet the FHFA-established benchmark of 6% or the overall market level of 5.8% for 2015.

If FHFA’s final determination is that we did not meet these housing goals, it will determine whether the goals were feasible. If FHFA finds that these goals were feasible, we may become subject to a housing plan that could require us to take additional steps that could have an adverse effect on our results of operations and financial condition. The housing plan must describe the actions we would take to meet the goal in the next calendar year and be approved by FHFA. The potential penalties for failure to comply with housing plan requirements include a cease-and-desist order and civil money penalties.

See “Business—Our Charter and Regulation of Our Activities—The GSE Act—Housing Goals and Duty to Serve Underserved Markets—Housing Goals for 2015 to 2017” in our 2015 Form 10-K for a more detailed discussion of our housing goals.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of financial statements in accordance with GAAP requires management to make a number of judgments, estimates and assumptions that affect the reported amount of assets, liabilities, income and expenses in the condensed consolidated financial statements. Understanding our accounting policies and the extent to which we use management judgment and estimates in applying these policies is integral to understanding our financial statements. We describe our most significant accounting policies in “Note 1, Summary of Significant Accounting Policies” in this report and in our 2015 Form 10-K.

We evaluate our critical accounting estimates and judgments required by our policies on an ongoing basis and update them as necessary based on changing conditions. Management has discussed any significant changes in judgments and assumptions in applying our critical accounting policies with the Audit Committee of our Board of Directors. See “Risk Factors” in our 2015 Form 10-K for a discussion of the risks associated with the need for management to make judgments and estimates in applying our accounting policies and methods. We have identified two of our accounting policies as critical because they involve significant judgments and assumptions about highly complex and inherently uncertain matters, and the use of reasonably different estimates and assumptions could have a material impact on our reported results of operations or financial condition: fair value measurement and combined loss reserves.

See “MD&A—Critical Accounting Policies and Estimates” in our 2015 Form 10-K for a discussion of these critical accounting policies and estimates.

Net Interest Income

We currently have two primary sources of net interest income: (1) the guaranty fees we receive for managing the credit risk on loans underlying Fannie Mae MBS held by third parties; and (2) the difference between interest income earned on the assets in our retained mortgage portfolio and the interest expense associated with the debt that funds those assets. We recognize almost all of our guaranty fee revenue in net interest income due to the consolidation of the substantial majority of loans underlying our Fannie Mae MBS in consolidated trusts on our balance sheet. Those guaranty fees are the primary component of the difference between the interest income on loans in consolidated trusts and the interest expense on the debt of consolidated trusts.

16

Table 4 displays an analysis of our net interest income, average balances, and related yields earned on assets and incurred on liabilities. For most components of the average balances, we use a daily weighted average of amortized cost. When daily average balance information is not available, such as for mortgage loans, we use monthly averages. Table 5 displays the change in our net interest income between periods and the extent to which that variance is attributable to: (1) changes in the volume of our interest-earning assets and interest-bearing liabilities or (2) changes in the interest rates of these assets and liabilities.

⁽²⁾  Includes cash equivalents.

Net interest income decreased in the third quarter and first nine months of 2016 compared with the third quarter and first nine months of 2015, primarily due to a decline in the average balance of our retained mortgage portfolio as we continued to reduce this portfolio pursuant to the requirements of our senior preferred stock purchase agreement with Treasury and FHFA’s additional portfolio cap. The average balance of our retained mortgage portfolio was 19% lower in the third quarter and first nine months of 2016 compared with the third quarter and first nine months of 2015. The decrease in net interest income was partially offset by increased guaranty fee revenue, as loans with higher guaranty fees became a larger part of our guaranty book of business in the third quarter and first nine months of 2016. Net interest yield decreased in the third quarter and first nine months of 2016 compared with the third quarter and first nine months of 2015, due to the decline in the percentage of net interest income from our retained mortgage portfolio, which has a higher net interest yield than the net interest yield from guaranty fees. See “Business Segment Results—The Capital Markets Group’s Mortgage Portfolio” for more information about our retained mortgage portfolio.

Fee and Other Income

Fee and other income includes transaction fees, multifamily fees, technology fees and other miscellaneous income. Fee and other income decreased in the third quarter of 2016 compared with the third quarter of 2015 primarily due to lower multifamily fees driven by a decrease in yield maintenance income resulting from lower prepayment volumes. Fee and other income decreased in the first nine months of 2016 compared with the first nine months of 2015 primarily due to a gain of $227 million in the second quarter of 2015 from the sale of our remaining unsecured bankruptcy claims against Lehman Brothers and its subsidiaries. In addition, we recognized lower multifamily fees in the first nine months of 2016 driven by a decrease in yield maintenance income resulting from lower prepayment volumes. We recognized lower technology fees in the first nine months of 2016 as a result of eliminating fees charged to our customers for using our Desktop Underwriter and Desktop Originator^® systems beginning in June 2015.

Investment Gains, Net

Investment gains, net primarily includes gains and losses recognized from the sale of available-for-sale (“AFS”) securities and loans, gains and losses recognized on the consolidation and deconsolidation of securities, net other-than-temporary impairments recognized on our investments, and lower of cost or fair value adjustments on HFS loans. Investment gains increased in the third quarter of 2016 compared with the third quarter of 2015 primarily due to higher gains on sales of AFS securities in the third quarter of 2016 compared with the third quarter of 2015 as a result of an increase in sales volume and higher prices in the third quarter of 2016. Investment gains decreased in the first nine months of 2016 compared with the first nine months of 2015 primarily due to gains on sales of multifamily loans in 2015 that did not occur in 2016 and greater losses on HFS loans due to lower of cost or fair value adjustments in the first nine months of 2016 compared with the first nine months of 2015.

Risk Management Derivatives Fair Value Gains (Losses), Net

Risk management derivative instruments are an integral part of our interest rate risk management strategy. We supplement our issuance of debt securities with derivative instruments to further reduce interest rate risk. We recognized risk management derivative fair value gains in the third quarter of 2016 primarily as a result of increases in the fair value of our pay-fixed derivatives due to increases in longer-term swap rates during the period. We recognized risk management derivative fair value losses in the third quarter of 2015 and first nine months of 2015 and 2016 primarily as a result of decreases in the fair value of our pay-fixed derivatives due to declines in longer-term swap rates during the periods.

We present, by derivative instrument type, the fair value gains and losses, net on our derivatives in “Note 9, Derivative Instruments.”

Mortgage Commitment Derivatives Fair Value Losses, Net

We recognized fair value losses on our mortgage commitments in the third quarter and first nine months of 2016 and 2015 primarily due to losses on commitments to sell mortgage-related securities driven by an increase in prices as interest rates decreased during the commitment periods.

20

CAS Debt Fair Value Gains (Losses), Net

We enter into various credit risk transfer transactions, including the issuance of CAS debt, in order to reduce the economic risk to us and to taxpayers of future borrower defaults. CAS debt we issued prior to 2016 is reported at fair value as “Debt of Fannie Mae” in our condensed consolidated balance sheets. We recognized fair value losses on CAS debt reported at fair value in the third quarter and first nine months of 2016 primarily due to tightening spreads between CAS yields and LIBOR during the periods. We recognized fair value gains on CAS debt reported at fair value in the third quarter and first nine months of 2015 primarily due to widening spreads between CAS yields and LIBOR during the periods. For further discussion of our credit risk transfer transactions, see “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management—Transfer of Mortgage Credit Risk—Credit Risk-Sharing Transactions.”

Administrative Expenses

Administrative expenses decreased in the third quarter and first nine months of 2016 compared with the third quarter and first nine months of 2015 primarily due to the recognition of expenses related to the settlement of our defined benefit pension plan obligations in the third quarter of 2015. The actuarial losses of $305 million, previously recorded in “Accumulated other comprehensive income,” were recognized in “Administrative expenses” and the associated tax amounts were recognized in “Provision for federal income taxes” in our condensed consolidated statements of operations and comprehensive income for the three and nine months ended September 30, 2015.

Credit-Related Income (Expense)

We refer to our provision (benefit) for loan losses and provision (benefit) for guaranty losses collectively as our “provision (benefit) for credit losses.” Credit-related income (expense) consists of our provision (benefit) for credit losses and foreclosed property expense (income).

Benefit for Credit Losses

Our total loss reserves provide for an estimate of credit losses incurred in our guaranty book of business, including concessions we granted borrowers upon modification of their loans. We establish our loss reserves through our provision for credit losses for losses that we believe have been incurred and will eventually be realized over time in our financial statements. When we reduce our loss reserves, we recognize a benefit for credit losses. When we determine that a loan is uncollectible, typically upon foreclosure or other liquidation event (such as a deed-in-lieu of foreclosure or a short sale), we recognize a charge-off against our loss reserves. For a subset of delinquent single-family loans, we charge off the portion of the loans that is deemed uncollectible prior to foreclosure when the loans have been delinquent for a specified length of time and meet specified mark-to-market LTV ratios. We also recognize charge-offs upon the redesignation of nonperforming loans from HFI to HFS. We record recoveries of previously charged-off amounts as a reduction to charge-offs.

Table 7 displays the components of our total loss reserves and our total fair value losses previously recognized on loans purchased out of unconsolidated MBS trusts reflected in our condensed consolidated balance sheets. Because these fair value losses lowered our recorded loan balances, we have fewer inherent losses in our guaranty book of business and consequently require lower total loss reserves. For these reasons, we consider these fair value losses as an “effective reserve,” apart from our total loss reserves, to the extent that we expect to realize these amounts as credit losses on the acquired loans in the future. The fair value losses shown in Table 7 represent credit losses we expect to realize in the future or amounts that will eventually be recovered, either through net interest income for loans that cure or through foreclosed property income for loans where the sale of the collateral exceeds our recorded investment in the loan. We exclude these fair value losses from our credit loss calculation as described in “Credit Loss Performance Metrics.”

⁽¹⁾  Represents the fair value losses on loans purchased out of unconsolidated MBS trusts reflected in our condensed consolidated balance sheets.

The reserve for guaranty losses decreased from December 31, 2015 to September 30, 2016 primarily due to increased collateral underlying certain trusts, as well as lower interest rates and higher home prices.

_________

⁽¹⁾  Our charge-offs for 2015 include the initial charge-offs associated with our approach to adopting the charge-off provisions of the Advisory Bulletin, as well as charge-offs relating to a change in accounting policy for nonaccrual loans.

⁽²⁾  Amounts represent changes in other loss reserves which are reflected in benefit for credit losses, charge-offs and recoveries.

The amount of our provision or benefit for credit losses may vary from period to period based on factors such as changes in actual and expected home prices, borrower payment behavior, the types and volumes of our loss mitigation activities, the volumes of foreclosures completed, redesignations of loans from HFI to HFS, and fluctuations in interest rates. In addition, our provision or benefit for credit losses and our loss reserves can be impacted by updates to the models, assumptions and data used in determining our allowance for loan losses.

Our benefit for credit losses decreased in the third quarter of 2016 compared to the third quarter of 2015 primarily due to a small increase in interest rates in the third quarter of 2016 compared to a decline in interest rates in the third quarter of 2015, as well as a smaller benefit from forecasted and actual home price increases as housing market conditions continued to improve and we had fewer nonperforming loans held for investment in our book of business in the third quarter of 2016 compared with the third quarter of 2015.

Our benefit for credit losses increased in the first nine months of 2016 compared to the first nine months of 2015 primarily due to declining interest rates in the first nine months of 2016 compared with increasing interest rates in the first nine months of 2015. Also contributing to the increase in our benefit for credit losses in the first nine months of 2016 was a smaller negative impact resulting from the redesignation of loans from HFI to HFS compared with the first nine months of 2015.

The following factors contributed to our benefit for credit losses in each of the periods presented:

We recognized a benefit for credit losses in the third quarter of 2016 primarily due to an increase in home prices, including distressed property valuations. Higher home prices decrease the likelihood that loans will default and reduce the amount of credit loss on loans that do default, which impacts our estimate of losses and ultimately reduces our total loss reserves and provision for credit losses.

We recognized a benefit for credit losses in the first nine months of 2016 due to higher home prices, including distressed property valuations, and a decline in interest rates. As interest rates decline, we expect an increase in future prepayments on single-family individually impaired loans, including modified loans. Higher expected prepayments shorten the expected lives of modified loans, which decreases the impairment relating to concessions provided on these loans and results in a decrease in the provision for credit losses.

We recognized a benefit for credit losses in the third quarter of 2015 primarily due to an increase in home prices and a decrease in interest rates.

We recognized a benefit for credit losses in the first nine months of 2015 primarily due to an increase in home prices. Additionally, our benefit for credit losses in the first nine months of 2015 was impacted by the redesignation of certain nonperforming single-family loans with an aggregate unpaid principal balance of $5.3 billion from HFI to HFS. These loans were adjusted to the lower of cost or fair value, which partially offset our benefit for credit losses. Interest rates increased during the first nine months of 2015, which also partially offset our benefit for credit losses in the first nine months of 2015. As interest rates increase, we expect a decline in future prepayments on individually impaired loans, including modified loans. Lower expected prepayments lengthen the expected lives of modified loans, which increases the impairment related to concessions provided on these loans and results in an increase in the provision for credit losses.

Our approach to the adoption of the charge-off provisions of the Advisory Bulletin on January 1, 2015 had no impact on the amount of benefit for credit losses that we recognized in the third quarter or first nine months of 2015.

We discuss our expectations regarding our future loss reserves in “Executive Summary—Outlook—Loss Reserves.”

Troubled Debt Restructurings and Nonaccrual Loans

Table 9 displays the composition of loans restructured in a troubled debt restructuring (“TDR”) that are on accrual status and loans on nonaccrual status. The table includes our recorded investment in HFI and HFS mortgage loans. For information on the impact of TDRs and other individually impaired loans on our allowance for loan losses, see “Note 3, Mortgage Loans.”

__________

⁽¹⁾  Includes loans that, as of the end of each period, are 90 days or more past due and continuing to accrue interest. The majority of these amounts consists of loans insured or guaranteed by the U.S. government and loans for which we have recourse against the seller in the event of a default.

⁽²⁾  Represents the amount of interest income we did not recognize, but would have recognized during the period for nonaccrual loans and TDRs on accrual status as of the end of each period had the loans performed according to their original contractual terms.

⁽³⁾  Represents interest income recognized during the period, including the amortization of any deferred cost basis adjustments, for loans classified as either nonaccrual loans or TDRs on accrual status as of the end of each period. Includes primarily amounts accrued while the loans were performing and cash payments received on nonaccrual loans.

Foreclosed Property Expense

Foreclosed property expense decreased in the third quarter and first nine months of 2016 compared with the third quarter and first nine months of 2015 primarily due to a decline in the number of foreclosed properties and lower operating expenses relating to property tax and insurance costs on our single-family foreclosed properties.

Credit Loss Performance Metrics

Our credit-related income (expense) should be considered in conjunction with our credit loss performance metrics. Our credit loss performance metrics, however, are not defined terms within GAAP and may not be calculated in the same manner as similarly titled measures reported by other companies. Because management does not view changes in the fair value of our mortgage loans as credit losses, we adjust our credit loss performance metrics for the impact associated with our acquisition of credit-impaired loans from unconsolidated MBS trusts. We also exclude interest forgone on nonaccrual loans and TDRs, other-than-temporary impairment losses resulting from deterioration in the credit quality of our mortgage-related securities and accretion of interest income on acquired credit-impaired loans from credit losses. We believe that credit loss performance metrics may be useful to investors as the losses are presented as a percentage of our book of business and have historically been used by analysts, investors and other companies within the financial services industry. Moreover, by presenting credit losses with and without the effect of fair value losses associated with the acquisition of credit-impaired loans, investors are

24

able to evaluate our credit performance on a more consistent basis among periods. Table 10 displays the components of our credit loss performance metrics as well as our single-family and multifamily initial charge-off severity rates.

Multifamily rate is net of risk-sharing agreements.

Credit losses and our credit loss ratio decreased in the third quarter of 2016 compared with the third quarter of 2015 primarily due to lower foreclosed property expense and lower charge-offs.

Credit losses and our credit loss ratio decreased in the first nine months of 2016 compared with the first nine months of 2015 primarily due to our approach to adopting the charge-off provisions of the Advisory Bulletin and a change in our accounting policy for nonaccrual loans in the first quarter of 2015. Additionally, lower charge-offs in the first nine months of 2016 compared with the first nine months of 2015 contributed to the decrease in our credit losses and credit loss ratio in the first nine months of 2016.

We discuss our expectations regarding our future credit losses in “Executive Summary—Outlook—Credit Losses.”

⁽¹⁾  Calculated based on the unpaid principal balance of loans, where we have detailed loan-level information, for each category divided by the unpaid principal balance of our single-family conventional guaranty book of business as of the end of each period.

⁽²⁾  Excludes the impact of recoveries resulting from resolution agreements related to representation and warranty matters and compensatory fee income related to servicing matters that have not been allocated to specific loans.

⁽³⁾  Includes Alt-A loans, subprime loans, interest-only loans, loans with original LTV ratios greater than 90% and loans with FICO credit scores less than 620.

⁽⁴⁾  Credit losses on mortgage loans typically do not peak until the third through sixth years following origination; however, this range can vary based on many factors, including changes in macroeconomic conditions and foreclosure timelines.

As shown in Table 11, the majority of our credit losses for the third quarter and first nine months of 2016 continued to be driven by loans originated in 2005 through 2008. Our credit losses in Florida, as well as credit losses on loans originated in 2005 through 2008, were higher in the third quarter and first nine months of 2015 compared with the third quarter and first nine months of 2016 primarily because, pursuant to the revised charge-off policy we implemented in 2015, we charged off a portion of excessively delinquent loans in these states that related to these vintages and that remained in the foreclosure process. We provide more detailed single-family credit performance information, including serious delinquency rates share and foreclosure activity, in “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management.”

Temporary Payroll Tax Cut Continuation Act of 2011 (“TCCA”) Fees

Pursuant to the TCCA, which was enacted by Congress in December 2011, FHFA directed us to increase our single-family guaranty fees by 10 basis points and remit this increase to Treasury. This TCCA-related revenue is included in “Net interest income” and the expense is recognized as “TCCA fees.” TCCA fees increased in the third quarter and first nine months of 2016 compared with the third quarter and first nine months of 2015 as our book of business subject to the TCCA continued to grow. We expect the guaranty fees collected and expenses incurred under the TCCA to continue to increase in the future.

BUSINESS SEGMENT RESULTS

Results of our three business segments are intended to reflect each segment as if it were a stand-alone business. Under our segment reporting structure, the sum of the results for our three business segments does not equal our condensed consolidated results of operations as we separate the activity related to our consolidated trusts from the results generated by our three segments. In addition, because we apply accounting methods that differ from our condensed consolidated results for segment reporting purposes, we reconcile the activity related to our consolidated trusts and other differences to our condensed consolidated results of operations. We describe the management reporting and allocation process used to generate our segment results in “Note 12, Segment Reporting” in our 2015 Form 10-K.

In this section, we provide a comparative discussion of our segment results for the third quarter and first nine months of 2016 and 2015. This section should be read together with our comparative discussion in “Consolidated Results of Operations.” See “Note 11, Segment Reporting” for a reconciliation of our segment results to our condensed consolidated results.

Single-Family Business Results

Table 12 displays the financial results of our Single-Family business. For a discussion of single-family credit risk management, including information on serious delinquency rates and loan workouts, see “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management.” The primary source of revenue for our Single-Family business is guaranty fee income. Expenses and other items that impact income or loss primarily include credit-related income (expense), TCCA fees and administrative expenses.

⁽⁹⁾  Information labeled as of September 30, 2016 is as of June 30, 2016 and is based on the Federal Reserve’s September 2016 mortgage debt outstanding release, the latest date for which the Federal Reserve has estimated mortgage debt outstanding for single-family residences. Prior period amounts have been changed to reflect revised historical data from the Federal Reserve.

⁽¹⁰⁾  Based on Freddie Mac’s Primary Mortgage Market Surveyrate for the last week in the period, which represents the national average mortgage commitment rate to a qualified borrower exclusive of any fees and points required by the lender.

Pre-tax income decreased in the third quarter of 2016 compared with the third quarter of 2015 primarily as a result of a decrease in credit-related income, partially offset by an increase in guaranty fee income. Pre-tax income increased in the first nine months of 2016 compared with the first nine months of 2015 primarily due to a shift to credit-related income from credit-related expense and higher guaranty fee income.

We recognized single-family credit-related income in the third quarter of 2016 and 2015. Credit-related income in the third quarter of 2016 was driven by a benefit for credit losses during the quarter, which was primarily attributable to an increase in home prices, including distressed property valuations. Higher home prices decrease the likelihood that loans will default and reduce the amount of credit loss on loans that do default, which impacts our estimate of losses and ultimately reduces our total loss reserves and provision for credit losses. Credit-related income in the third quarter of 2015 was driven by a benefit for credit losses that was primarily attributable to an increase in home prices as well as a decrease in interest rates during the period. As interest rates decline, we expect an increase in future prepayments on single-family individually impaired loans, including modified loans. Higher expected prepayments shorten the expected lives of modified loans, which decreases the impairment relating to concessions provided on these loans and results in a decrease in our provision for credit losses.

We recognized single family credit-related income in the first nine months of 2016. In comparison, we recognized credit-related expense in the first nine months of 2015. Credit-related income in the first nine months of 2016 was primarily attributable to a benefit for credit losses during the period, driven by an increase in home prices, including distressed property valuations, and a decrease in interest rates. Credit-related expense in the first nine months of 2015 was comprised of foreclosed property expense, partially offset by a benefit for credit losses. Foreclosed property expense in the first nine months of 2015 was primarily driven by property preservation costs, which include property tax and insurance expenses relating to our single-family foreclosed properties. The benefit for credit losses in the first nine months of 2015 was primarily driven by higher home prices. This was partially offset by the impact from the redesignation of certain nonperforming single-family loans from HFI to HFS. These loans were adjusted to the lower of cost or fair value, which reduced our benefit for credit losses. Additionally, interest rates increased during the first nine months of 2015, which also partially offset our benefit for credit losses. See “Consolidated Results of Operations—Credit-Related Income (Expense)” for more information on the drivers of our credit-related income or expense.

Guaranty fee income and our effective guaranty fee rate increased in the third quarter and first nine months of 2016 compared with the third quarter and first nine months of 2015 as loans with higher guaranty fees have become a larger part of our single-family guaranty book of business primarily due to the cumulative impact of guaranty fee price increases implemented in 2012.

Our single-family acquisition volume and single-family Fannie Mae MBS issuances increased in the third quarter of 2016 compared with the third quarter of 2015, driven primarily by an increase in refinances. Our single-family acquisition volume and single-family MBS issuances increased in the first nine months of 2016 compared with the first nine months of 2015, driven primarily by an increase in acquisitions of home purchase mortgage loans. The increase in acquisition volumes in the first nine months of 2016 compared with the first nine months of 2015 was partially offset by an increase in liquidations of loans from our single-family guaranty book of business. Accordingly, the size of our single-family guaranty book of business remained relatively flat.

Multifamily Business Results

Multifamily business results primarily reflect our multifamily guaranty business. Our Multifamily business results also include activity relating to our low-income housing tax credit (“LIHTC”) investments and equity investments. Although we are not currently making new LIHTC or equity investments, we continue to make contractually required contributions for our legacy investments. Activity from multifamily products is also reflected in the Capital Markets group results, which include net interest income related to multifamily loans and securities held in our retained mortgage portfolio, gains and losses from the sale of multifamily Fannie Mae MBS, mortgage loans and re-securitizations, and other miscellaneous income.

Table 13 displays the financial results of our Multifamily business. The primary sources of revenue for our Multifamily business are guaranty fee income and fee and other income, which includes yield maintenance income. Other items that affect income or loss primarily include credit-related income (expense), gains on partnership investments, and administrative expenses.

⁽³⁾  Consists of net interest income (loss), investment gains (losses), net, administrative expenses and other expenses.

⁽⁴⁾  Reflects unpaid principal balance of multifamily Fannie Mae MBS issued (excluding portfolio securitizations), multifamily loans purchased, and credit enhancements provided during the period.

⁽⁵⁾  Reflects unpaid principal balance of multifamily Fannie Mae MBS issued during the period. Includes (a) issuances of new MBS as a result of lender swap transactions; (b) Fannie Mae portfolio securitization transactions of which we had none for the three and nine months ended September 30, 2016, and $189 million and $1.6 billion for the three and nine months ended September 30, 2015; and (c) conversions of adjustable-rate loans to fixed-rate loans of $118 million and $4 million for the nine months ended September 30, 2016 and 2015, respectively; and no conversions for the three months ended September 30, 2016 and 2015; and (d) MBS reissuances of $19 millionfor the three and nine months ended September 30, 2016, $56 million for the nine months ended September 30, 2015 and no reissuances for the three months ended September 30, 2015.

⁽⁶⁾  Includes $8.4 billion and $13.8 billion of Fannie Mae multifamily MBS held in our retained mortgage portfolio, the vast majority of which have been consolidated to loans in our condensed consolidated balance sheets, as of September 30, 2016 and 2015, respectively.

⁽⁷⁾  Our multifamily guaranty book of business consists of (a) multifamily mortgage loans of Fannie Mae, (b) multifamily mortgage loans underlying Fannie Mae MBS, and (c) other credit enhancements that we provide on multifamily mortgage assets. It excludes non-Fannie Mae mortgage-related securities held in our retained mortgage portfolio for which we do not provide a guaranty.

⁽⁸⁾  Calculated based on annualized Multifamily segment guaranty fee income divided by the average multifamily guaranty book of business.

⁽⁹⁾  Calculated based on annualized Multifamily segment credit losses divided by the average multifamily guaranty book of business. Negative credit losses are the result of recoveries on previously charged-off amounts.

⁽¹⁰⁾  Includes mortgage loans and Fannie Mae MBS guaranteed by the Multifamily segment. Information labeled as of September 30, 2016 is as of June 30, 2016 and is based on the Federal Reserve’s September 2016 mortgage debt outstanding release, the latest date for which the Federal Reserve has estimated mortgage debt outstanding for multifamily residences. Prior period amounts may have been changed to reflect revised historical data from the Federal Reserve.

⁽¹¹⁾  Based on unpaid principal balance.

⁽¹²⁾  Interest expense estimate is based on allocated duration-matched funding costs. Net interest income was reduced by guaranty fees allocated to Multifamily from the Capital Markets group on multifamily loans in our retained mortgage portfolio. Yield maintenance income represents the investor portion of fees earned as a result of prepayments of multifamily loans and MBS in our retained mortgage portfolio. A portion of yield maintenance income is reported in Multifamily business results to the extent attributable to our multifamily guaranty business.

Pre-tax income increased in the third quarter of 2016 compared with the third quarter of 2015 primarily as a result of an increase in guaranty fee income. Pre-tax income decreased in the first nine months of 2016 compared with the first nine months of 2015 primarily as a result of decreases in gains from partnership investments, credit-related income and fee and other income, partially offset by an increase in guaranty fee income.

Guaranty fee income increased in the third quarter and first nine months of 2016 compared with the third quarter and first nine months of 2015 as loans with higher guaranty fees have become a larger part of our multifamily guaranty book of business, while loans with lower guaranty fees continued to liquidate.

Fee and other income decreased in the first nine months of 2016 compared with the first nine months of 2015 primarily due to a decrease in yield maintenance income as a result of lower prepayment volumes in the first nine months of 2016.

Gains from partnership investments decreased in the first nine months of 2016 compared with the first nine months of 2015 as the number of our multifamily partnership investments continued to decline.

Credit-related income decreased in the first nine months of 2016 compared with the first nine months of 2015 primarily driven by a lower benefit from the reduction in the allowance for loan losses.

FHFA’s 2016 conservatorship scorecard includes an objective to maintain the dollar volume of new multifamily business at or below $36.5 billion, excluding certain targeted business segments. On August 18, 2016, FHFA announced an increase in the 2016 multifamily lending caps for Fannie Mae and Freddie Mac from $35 billion to $36.5 billion. Approximately 66% of Fannie Mae’s multifamily new business volume of $40.7 billion for the first nine months of 2016 counted towards FHFA’s 2016 multifamily volume cap.

Derivative Instruments” in this report and our 2015 Form 10-K. The primary source of revenue for our Capital Markets group is net interest income. Other items that impact income or loss primarily include fair value gains and losses, investment gains and losses, as well as allocated guaranty fee expense and administrative expenses.

__________

⁽¹⁾  Includes contractual interest income, excluding recoveries, on nonaccrual loans received from the Single-Family segment of $421 million and $480 million for the three months ended September 30, 2016 and 2015, respectively, and $1.4 billion and $1.6 billion for the nine months ended September 30, 2016 and 2015, respectively. The Capital Markets group’s net interest income is reported based on the mortgage-related assets held in the segment’s retained mortgage portfolio and excludes interest income on mortgage-related assets held by consolidated MBS trusts that are owned by third parties and the interest expense on the corresponding debt of such trusts.

⁽²⁾  We include the securities that we own regardless of whether the trust has been consolidated in reporting of gains and losses on securitizations and sales of available-for-sale securities.

⁽³⁾  Includes fair value losses on derivatives and fair value gains on trading securities that we own regardless of whether the trust has been consolidated.

⁽⁴⁾  Includes allocated guaranty fee expense, administrative expenses, and other expenses.

Pre-tax income increased in the third quarter of 2016 compared with the third quarter of 2015 primarily due to a decrease in fair value losses and an increase in investment gains, partially offset by a decrease in net interest income. Pre-tax income decreased in the first nine months of 2016 compared with the first nine months of 2015 primarily due to an increase in fair value losses and a decrease in net interest income, partially offset by an increase in investment gains.

Fair value losses in the third quarter of 2016 were primarily driven by losses on CAS debt carried at fair value primarily due to tightening spreads between CAS debt yields and LIBOR during the period. Fair value losses in the first nine months of 2016 were primarily due to fair value losses on our risk management derivatives. The fair value losses that are reported for the Capital Markets group are consistent with the amounts reported in our condensed consolidated statements of operations and comprehensive income, which we discuss in “Consolidated Results of Operations—Fair Value Losses, Net.”

The decrease in net interest income in the third quarter and first nine months of 2016 compared with the third quarter and first nine months of 2015 was primarily due to a decline in the average balance of our retained mortgage portfolio as we continued to reduce this portfolio pursuant to the requirements of our senior preferred stock purchase agreement with Treasury and FHFA’s additional portfolio cap.

Investment gains increased in the third quarter and first nine months of 2016 compared with the third quarter and first nine months of 2015 primarily due to higher gains recognized on the sale of AFS securities as a result of an increase in sales volume and higher prices in the third quarter and first nine months of 2016.

We supplement our issuance of debt securities with derivative instruments to further reduce interest rate risk. The effect of these derivatives, in particular the periodic net interest expense accruals on interest rate swaps, is not reflected in the Capital Markets group’s net interest income but is included in our results as a component of “Fair value losses, net” and is displayed in “Table 6: Fair Value Losses, Net.”

The Capital Markets Group’s Mortgage Portfolio

The Capital Markets group’s mortgage portfolio, which we also refer to as our retained mortgage portfolio, consists of mortgage loans and mortgage-related securities that we own. Mortgage-related securities held by the Capital Markets group include Fannie Mae MBS and non-Fannie Mae mortgage-related securities. The Fannie Mae MBS that we own are maintained as securities on the Capital Markets group’s balance sheets. The portion of assets held by consolidated MBS trusts that back mortgage-related securities owned by third parties are not included in the Capital Markets group’s mortgage portfolio.

The amount of mortgage assets that we may own is restricted by our senior preferred stock purchase agreement with Treasury. By December 31 of each year, we are required to reduce our mortgage assets to 85% of the maximum allowable amount that we were permitted to own as of December 31 of the immediately preceding calendar year, until the amount of our mortgage assets reaches $250 billion in 2018. Under the agreement, the maximum allowable amount of mortgage assets we are permitted to own as of December 31, 2016 is $339.3 billion.

In 2014, FHFA requested that we submit a revised portfolio plan outlining how we will reduce the portfolio each year to 90% of the annual limit under our senior preferred stock purchase agreement with Treasury. FHFA’s request noted that we may seek FHFA permission to increase this cap up to 95% of the annual limit under our senior preferred stock purchase agreement with Treasury upon written request and with a documented basis for exception, such as changed market conditions. Accordingly, under our revised portfolio plan, we plan to reduce our retained mortgage portfolio to no more than $305.4 billion as of December 31, 2016, in compliance with both our senior preferred stock purchase agreement with Treasury and FHFA’s request.

In the third quarter of 2016, we began to securitize reperforming loans held in our retained mortgage portfolio into Fannie Mae MBS, and also began to sell Fannie Mae MBS backed by reperforming loans. Reperforming loans are mortgage loans on which the borrower had previously been delinquent but subsequently became current, either with or without a modification. Our securitization and sale of Fannie Mae MBS backed by reperforming loans provides us with more flexibility to manage our risk and reduce the size of our portfolio. In addition, in October 2016, we announced our first offer to sell reperforming whole loans as part of our ongoing effort to reduce the size of our retained mortgage portfolio.

As we continue to reduce the size of our retained mortgage portfolio, our revenues generated by our retained mortgage portfolio will continue to decrease. As of September 30, 2016, we owned $306.5 billion in mortgage assets, compared with $345.1 billion as of December 31, 2015. For additional information on the terms of the senior preferred stock purchase agreement with Treasury, see “Business—Conservatorship and Treasury Agreements—Treasury Agreements” in our 2015 Form 10-K.

Table 16 displays the composition of the unpaid principal balance of our Capital Markets group’s mortgage portfolio and our assessment of the liquidity of these assets. Our assessment is based on the liquidity within the markets in which the assets are traded, the issuers of the assets and the nature of the collateral underlying the assets. Our unsecuritized mortgage loans, private-label mortgage-related securities (“PLS”) and other non-agency securities are considered less liquid. Fannie Mae securities that are collateralized by non-agency mortgage-related securities are also considered to be less liquid.

⁽¹⁾  The fair value of these mortgage-related securities was $76.2 billion and $96.0 billion as of September 30, 2016 and December 31, 2015, respectively.

Our Capital Markets group’s mortgage portfolio decreased as of September 30, 2016 compared with December 31, 2015, as we continued to reduce the size of our retained mortgage portfolio. The overall portfolio decrease was driven by sales and liquidations outpacing purchases.

The loans we purchased in the first nine months of 2016 included $8.5 billion in delinquent loans we purchased from our single-family MBS trusts. We expect to continue purchasing loans from MBS trusts as they become four or more consecutive monthly payments delinquent subject to market conditions, economic benefit, servicer capacity and other factors, including the limit on the amount of mortgage assets that we may own pursuant to the senior preferred stock purchase agreement and FHFA’s portfolio plan requirements. Table 17 displays the composition of loans restructured in a TDR that were on accrual status, loans on nonaccrual status and all other mortgage-related assets in our Capital Markets group’s mortgage portfolio.

⁽¹⁾  Includes $31.3 billion as of September 30, 2016 and $29.5 billion as of December 31, 2015 of U.S. Treasury securities that are included in our other investments portfolio, which we present in “Table 22: Cash and Other Investments Portfolio.”

36

Cash and Other Investments Portfolio

Our cash and other investments portfolio consists of cash and cash equivalents, securities purchased under agreements to resell or similar arrangements, and investments in U.S. Treasury securities. See “Liquidity and Capital Management—Liquidity Management—Cash and Other Investments Portfolio” for additional information on our cash and other investments portfolio.

Restricted Cash

Restricted cash primarily includes unscheduled borrower payments received by servicers of loans backing consolidated trusts due to be remitted to the MBS certificateholders in the subsequent month. Our restricted cash increased as of September 30, 2016 compared with the balance as of December 31, 2015 primarily as a result of an increase in prepayments received on mortgage loans in September 2016 compared with prepayments received in December 2015.

Investments in Mortgage-Related Securities

Our investments in mortgage-related securities are classified in our condensed consolidated balance sheets as either trading or available-for-sale and are measured at fair value. Table 19 displays the fair value of our investments in mortgage-related securities, including trading and available-for-sale securities. We classify private-label securities as Alt-A, subprime or commercial mortgage-backed securities (“CMBS”) if the securities were labeled as such when issued. We have also invested in subprime private-label securities that we have resecuritized to include our guaranty.

Table 19: Summary of Mortgage-Related Securities at Fair Value

	As of
	September 30, 2016			December 31, 2015
	(Dollars in millions)
Mortgage-related securities:
Fannie Mae		$	7,643		$	9,034
Freddie Mac		1,390			5,613
Ginnie Mae		1,454			817
Alt-A private-label securities		1,730			3,114
Subprime private-label securities		2,272			3,925

Mortgage revenue bonds		1,916			3,150
Other mortgage-related securities		471			1,404
Total		$	19,135		$	30,653

The decrease in mortgage-related securities at fair value from December 31, 2015 to September 30, 2016 was primarily driven by sales and liquidations.

Mortgage Loans

The increase in mortgage loans from December 31, 2015 to September 30, 2016 was primarily due to acquisitions outpacing liquidations. For additional information on our mortgage loans, see “Note 3, Mortgage Loans.” For additional information on our mortgage loan purchase and sale activities, see “Business Segment Results—Capital Markets Group Results.”

The decrease in our allowance for loan losses from December 31, 2015 to September 30, 2016 was primarily driven by increases in home prices, declines in actual and projected interest rates, liquidations of mortgage loans and charge-offs which relieved the allowance on these loans. See “Consolidated Results of Operations—Credit-Related Income (Expense)” for more information.

Debt

Debt of Fannie Mae is the primary means of funding our mortgage investments. The decrease in debt of Fannie Mae from December 31, 2015 to September 30, 2016 was primarily driven by lower funding needs, as our retained mortgage portfolio decreased. We provide a summary of the activity of the debt of Fannie Mae and a comparison of the mix between our outstanding short-term and long-term debt in “Liquidity and Capital Management—Liquidity Management—Debt Funding.” Also see “Note 8, Short-Term Borrowings and Long-Term Debt” for additional information on our outstanding debt.

37

Debt of consolidated trusts represents the amount of Fannie Mae MBS issued from consolidated trusts and held by third-party certificateholders. The increase in debt of consolidated trusts from December 31, 2015 to September 30, 2016 was primarily driven by sales of Fannie Mae MBS, which are accounted for as reissuances of debt of consolidated trusts in our condensed consolidated balance sheets, since the MBS certificate ownership is transferred from us to a third party.

Stockholders’ Equity

Our equity increased as of September 30, 2016 compared with December 31, 2015 due to our comprehensive income recognized during the first nine months of 2016, offset by our payments of senior preferred stock dividends to Treasury during the first nine months of 2016.

LIQUIDITY AND CAPITAL MANAGEMENT

Liquidity Management

Our business activities require that we maintain adequate liquidity to fund our operations. Our liquidity risk management framework is designed to address our liquidity risk. Liquidity risk is the risk that we will not be able to meet our funding obligations in a timely manner. Liquidity risk management involves forecasting funding requirements, maintaining sufficient capacity to meet our needs based on our ongoing assessment of financial market liquidity and adhering to our regulatory requirements.

Our treasury group is responsible for implementing our liquidity and contingency planning strategies. We hold a portfolio of highly liquid investments and maintain access to alternative sources of liquidity which are designed to provide near term availability of cash in the event that our access to the debt markets becomes limited. While our liquidity contingency planning attempts to address stressed market conditions, we believe that our liquidity contingency plan may be difficult or impossible to execute for a company of our size and in our circumstances.

Our liquidity position could be adversely affected by many factors, both internal and external to our business, including: actions taken by FHFA, the Federal Reserve, Treasury or other government agencies; legislation relating to us or our business; a U.S. government payment default on its debt obligations; a downgrade in the credit ratings of our senior unsecured debt or the U.S. government’s debt from the major ratings organizations; a systemic event leading to the withdrawal of liquidity from the market; an extreme market-wide widening of credit spreads; public statements by key policy makers; a significant decline in our net worth; potential investor concerns about the adequacy of funding available to us under the senior preferred stock purchase agreement; loss of demand for our debt, or certain types of our debt, from a major group of investors; a significant credit event involving one of our major institutional counterparties; a sudden catastrophic operational failure in the financial sector; or elimination of our GSE status.

This section supplements and updates information regarding liquidity risk management contained in our 2015 Form 10-K. See “MD&A—Liquidity and Capital Management—Liquidity Management” and “Risk Factors” in our 2015 Form 10-K for additional information, including discussions of our primary sources and uses of funds, our liquidity risk management practices and liquidity contingency planning, factors that influence our debt funding activity, factors that may impact our access to or the cost of our debt funding, and factors that could adversely affect our liquidity.

Debt Funding

We fund our business primarily through the issuance of short-term and long-term debt securities in the domestic and international capital markets. Because debt issuance is our primary funding source, we are subject to “roll over,” or refinancing, risk on our outstanding debt.

Our debt funding needs and debt funding activity may vary from quarter to quarter depending on market conditions and are influenced by anticipated liquidity needs, the size of our retained mortgage portfolio and our dividend payment obligations to Treasury. See “Business Segment Results—Capital Markets Group Results—The Capital Markets Group’s Mortgage Portfolio” for information about our retained mortgage portfolio, our requirement to reduce the size of our retained mortgage portfolio and our portfolio reduction plan.

38

Fannie Mae Debt Funding Activity

Table 20 displays the activity in debt of Fannie Mae. This activity excludes the debt of consolidated trusts and intraday loans. Activity for short-term debt of Fannie Mae relates to borrowings with an original contractual maturity of one year or less while activity for long-term debt of Fannie Mae relates to borrowings with an original contractual maturity of greater than one year. The reported amounts of debt issued and paid off during the period represent the face amount of the debt at issuance and redemption. The increase in our issuances and payoffs of short-term debt during the first nine months of 2016 compared with the first nine months of 2015 was driven by our utilization of short-term notes with overnight maturities in the first nine months of 2016. The increase in our issuances of long-term debt during the third quarter and first nine months of 2016 compared with the third quarter and first nine months of 2015 was primarily driven by the issuance of debt to fund higher redemptions of callable debt due to lower interest rates.

⁽¹⁾  Includes credit risk-sharing securities issued under our CAS series. For additional information on our credit risk-sharing transactions, see “Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management—Transfer of Mortgage Credit Risk—Credit Risk-Sharing Transactions.”

⁽²⁾  Consists of all payments on debt, including regularly scheduled principal payments, payments at maturity, payments resulting from calls and payments for any other repurchases. Repurchases of debt and early retirements of zero-coupon debt are reported at original face value, which does not equal the amount of actual cash payment.

Outstanding Debt

Total outstanding debt of Fannie Mae includes short-term and long-term debt, excluding debt of consolidated trusts. Short-term debt of Fannie Mae consists of borrowings with an original contractual maturity of one year or less and, therefore, does not include the current portion of long-term debt. Long-term debt of Fannie Mae consists of borrowings with an original contractual maturity of greater than one year.

39

Our outstanding short-term debt, based on its original contractual maturity, as a percentage of our total outstanding debt, was 15% as of September 30, 2016, compared with 18% as of December 31, 2015. The weighted-average interest rate on our long-term debt, based on its original contractual maturity, decreased to 2.28% as of September 30, 2016 from 2.41% as of December 31, 2015.

Our outstanding debt maturing within one year, including the current portion of our long-term debt and amounts we have announced for early redemption, as a percentage of our total outstanding debt, excluding debt of consolidated trusts, was 33% as of September 30, 2016 and 32% as of December 31, 2015. The weighted-average maturity of our outstanding debt that is maturing within one year was 143 days as of September 30, 2016, compared with 125 days as of December 31, 2015. The weighted-average maturity of our outstanding debt maturing in more than one year was approximately 54 months as of September 30, 2016, compared with approximately 57 months as of December 31, 2015.

We intend to repay our short-term and long-term debt obligations as they become due primarily through proceeds from the issuance of additional debt securities. We also may use proceeds from our mortgage assets to pay our debt obligations.

Pursuant to the terms of the senior preferred stock purchase agreement, we are prohibited from issuing debt without the prior consent of Treasury if it would result in our aggregate indebtedness exceeding our outstanding debt limit, which is 120% of the amount of mortgage assets we were allowed to own under the senior preferred stock purchase agreement on December 31 of the immediately preceding calendar year. Our debt limit under the senior preferred stock purchase agreement was reduced to $479.0 billion in 2016. As of September 30, 2016, our aggregate indebtedness totaled $353.6 billion, which was $125.4 billion below our debt limit. The calculation of our indebtedness for purposes of complying with our debt limit reflects the unpaid principal balance and excludes debt basis adjustments and debt of consolidated trusts. Because of our debt limit, we may be restricted in the amount of debt we issue to fund our operations.

Credit Ratings

As of September 30, 2016, our credit ratings have not changed since we filed our 2015 Form 10-K. For additional information on our credit ratings, see “MD&A—Liquidity and Capital Management—Credit Ratings” in our 2015 Form 10-K.

Cash Flows

Nine Months EndedSeptember 30, 2016. Cash and cash equivalents increased by $11.9 billion from $14.7 billion as of December 31, 2015 to $26.6 billion as of September 30, 2016. The increase was primarily driven by cash inflows from (1) the sale of Fannie Mae MBS to third parties, (2) proceeds from repayments and sales of loans of Fannie Mae and (3) proceeds from the sale and liquidation of mortgage-related securities.

Partially offsetting these cash inflows were cash outflows from (1) the redemption of funding debt, which outpaced issuances due to lower funding needs, (2) the acquisition of delinquent loans out of MBS trusts and (3) the payment of dividends to Treasury under our senior preferred stock purchase agreement.

Nine Months Ended September 30, 2015. Cash and cash equivalents decreased by $2.1 billion from $22.0 billion as of December 31, 2014 to $19.9 billion as of September 30, 2015. The decrease was primarily driven by cash outflows from (1) the redemption of funding debt, which outpaced issuances due to lower funding needs, (2) the acquisition of delinquent loans out of MBS trusts and (3) the payment of dividends to Treasury under our senior preferred stock purchase agreement.

Partially offsetting these cash outflows were cash inflows from (1) proceeds from repayments and sales of loans of Fannie Mae, (2) the sale of Fannie Mae MBS to third parties, (3) the sale of our acquired property and (4) proceeds from the sale and liquidation of mortgage-related securities.

Capital Management

Regulatory Capital

FHFA stated that, during conservatorship, our existing statutory and FHFA-directed regulatory capital requirements will not be binding and FHFA will not issue quarterly capital classifications. The deficit of our core capital over statutory minimum capital was $138.9 billion as of September 30, 2016 and $139.7 billion as of December 31, 2015. For more information on our minimum capital requirements, see “Note 14, Regulatory Capital Requirements” in our 2015 Form 10-K.

Capital Activity

The Director of FHFA has directed us to make dividend payments on the senior preferred stock on a quarterly basis. Our third quarter 2016 dividend of $2.9 billion was declared by FHFA and subsequently paid by us on September 30, 2016. Based on the terms of the senior preferred stock, we expect to pay Treasury a dividend for the fourth quarter of 2016 of $3.0 billion by December 31, 2016.

42

The terms of our senior preferred stock provide for dividends to accrue at a rate equal to our net worth less a capital reserve amount, which continues to decrease annually. The capital reserve amount is $1.2 billion for dividend periods in 2016, and will continue to be reduced by $600 million each year until it reaches zero on January 1, 2018.

We are effectively unable to raise equity capital from private sources at this time and, therefore, are reliant on the funding available under our senior preferred stock purchase agreement with Treasury to address any net worth deficit. Under the senior preferred stock purchase agreement, Treasury made a commitment to provide funding, under certain conditions, to eliminate deficiencies in our net worth. We have received a total of $116.1 billion from Treasury pursuant to the senior preferred stock purchase agreement as of September 30, 2016. The current aggregate liquidation preference of the senior preferred stock, including the initial aggregate liquidation preference of $1.0 billion, remains at $117.1 billion.

While we had a positive net worth as of September 30, 2016 and have not received funds from Treasury under the agreement since the first quarter of 2012, we will be required to obtain additional funding from Treasury pursuant to the senior preferred stock purchase agreement if we have a net worth deficit in future periods. As of the date of this filing, the amount of remaining available funding under the senior preferred stock purchase agreement is $117.6 billion. If we were to draw additional funds from Treasury under the agreement in a future period, the amount of remaining funding under the agreement would be reduced by the amount of our draw. Dividend payments we make to Treasury do not restore or increase the amount of funding available to us under the agreement.

See “Business—Conservatorship and Treasury Agreements—Treasury Agreements” in our 2015 Form 10-K for more information on the terms of the senior preferred stock and our senior preferred stock purchase agreement with Treasury. See “Risk Factors” in our 2015 Form 10-K for a discussion of the risks relating to our dividend obligations to Treasury on the senior preferred stock. See “Risk Factors” in this report for a discussion of how changes in accounting standards could have a material adverse effect on our financial results or net worth.

OFF-BALANCE SHEET ARRANGEMENTS

Our maximum potential exposure to credit losses relating to our outstanding and unconsolidated Fannie Mae MBS and other financial guarantees is primarily represented by the unpaid principal balance of the mortgage loans underlying outstanding and unconsolidated Fannie Mae MBS and other financial guarantees of $25.1 billion as of September 30, 2016 and $27.5 billion as of December 31, 2015.

For a description of our off-balance sheet arrangements, see “MD&A—Off-Balance Sheet Arrangements” in our 2015 Form 10-K.

RISK MANAGEMENT

Our business activities expose us to the following three major categories of risk: credit risk, market risk (including interest rate and liquidity risk) and operational risk. We seek to actively monitor and manage these risks by using an established risk management framework. In addition to our exposure to credit, market and operational risks, there is significant uncertainty regarding the future of our company, including how long we will continue to be in existence, which we discuss in more detail in “Risk Factors” in this report and in “Business—Housing Finance Reform” in our 2015 Form 10-K. This uncertainty, along with limitations on our employee compensation arising from our conservatorship, could adversely affect our ability to retain and hire qualified employees.

We are also subject to a number of other risks that could adversely impact our business, financial condition and earnings including human capital, model, legal, regulatory and compliance, reputational, technological and cybersecurity, strategic and execution risks. These risks may arise due to a failure to comply with laws, regulations or ethical standards and codes of conduct applicable to our business activities and functions.

In this section we provide an update on our management of our major risk categories. For a more complete discussion of the primary risks we face and how we manage credit risk, market risk and operational risk, see “MD&A—Risk Management” in our 2015 Form 10-K and “Risk Factors” in this report and our 2015 Form 10-K.

Credit Risk Management

We are generally subject to two types of credit risk: mortgage credit risk and institutional counterparty credit risk. Mortgage credit risk is the risk that a borrower will fail to make required mortgage payments. Institutional counterparty credit risk is the risk that our institutional counterparties may fail to fulfill their contractual obligations to us.

43

Mortgage Credit Risk Management

We are exposed to credit risk on our mortgage credit book of business because we either hold mortgage assets, have issued a guaranty in connection with the creation of Fannie Mae MBS backed by mortgage assets or provided other credit enhancements on mortgage assets. While our mortgage credit book of business includes all of our mortgage-related assets, both on- and off-balance sheet, our guaranty book of business excludes non-Fannie Mae mortgage-related securities held in our retained mortgage portfolio for which we do not provide a guaranty. We provide information on the performance of non-Fannie Mae mortgage-related securities held in our retained mortgage portfolio, including the impairment that we have recognized on these securities, in “Note 5, Investments in Securities.”

Mortgage Credit Book of Business

Table 23 displays the composition of our mortgage credit book of business based on unpaid principal balance. Our single-family mortgage credit book of business accounted for 92% of our mortgage credit book of business as of September 30, 2016 and 93% of our mortgage credit book of business as of December 31, 2015.

The GSE Act requires us to set aside each year an amount equal to 4.2 basis points for each dollar of the unpaid principal balance of our total new business purchases and to pay this amount to specified U.S. Department of Housing and Urban Development and Treasury funds. New business purchases consist of single-family and multifamily whole mortgage loans purchased during the period and single-family and multifamily mortgage loans underlying Fannie Mae MBS issued during the period pursuant to lender swaps. In February 2016, we paid $217 million to the funds based on our new business purchases in 2015. Our new business purchases were $444.5 billion in the first nine months of 2016. Accordingly, we recognized an expense of $187 million related to this obligation for the first nine months of 2016. We expect to pay this amount, plus additional amounts to be accrued based on our new business purchases in the last three months of 2016, to the funds in February 2017. See “Business—Our Charter and Regulation of Our Activities—The GSE Act—Affordable Housing Allocations” in our 2015 Form 10-K for more information regarding this obligation.

In the following sections, we discuss the mortgage credit risk of the single-family and multifamily loans in our guaranty book of business. The credit statistics reported below, unless otherwise noted, pertain generally to the portion of our guaranty book of business for which we have access to detailed loan-level information, which constituted approximately 99% of each of our single-family conventional guaranty book of business and our multifamily guaranty book of business, excluding defeased loans, as of September 30, 2016 and December 31, 2015. We typically obtain this data from the sellers or servicers of the mortgage loans in our guaranty book of business and receive representations and warranties from them as to the accuracy of the information. While we perform various quality assurance checks by sampling loans to assess compliance with our underwriting and eligibility criteria, we do not independently verify all reported information and we rely on lender representations regarding the accuracy of the characteristics of loans in our guaranty book of business. See “Risk Factors” in our 2015 Form 10-K for a discussion of the risk that we could experience mortgage fraud as a result of this reliance on lender representations.

Single-Family Mortgage Credit Risk Management

Our strategy in managing single-family mortgage credit risk consists of five primary components: (1) our acquisition and servicing policies along with our underwriting and servicing standards; (2) the transfer of credit risk through risk-sharing transactions and the use of credit enhancements; (3) portfolio diversification and monitoring; (4) management of problem loans; and (5) REO management. We provide information on our credit-related income and credit losses in “Consolidated Results of Operations—Credit-Related Income (Expense).” For information on how we evaluate and factors that affect our single-family mortgage credit risk, see “MD&A—Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management” in our 2015 Form 10-K.

The single-family credit statistics we focus on and report in the sections below generally relate to our single-family conventional guaranty book of business, which represents the substantial majority of our total single-family guaranty book of business. We provide information on non-Fannie Mae mortgage-related securities held in our portfolio in “Note 5, Investments in Securities.”

Single-Family Acquisition and Servicing Policies and Underwriting and Servicing Standards

Our Single-Family business, with the oversight of our Enterprise Risk Management division, is responsible for pricing and managing credit risk relating to the portion of our single-family mortgage credit book of business consisting of single-family mortgage loans and Fannie Mae MBS backed by single-family mortgage loans (whether held in our portfolio or held by third parties). Desktop Underwriter, our proprietary automated underwriting system which measures credit risk by assessing the primary risk factors of a mortgage, is used to evaluate the majority of the loans we purchase or securitize. We periodically update Desktop Underwriter to reflect changes to both our underwriting and eligibility guidelines and our Selling Guide, which sets forth our policies and procedures related to selling single-family mortgages to us.

We initiated underwriting and eligibility changes that became effective for deliveries in late 2008 and 2009 and that focused on strengthening our underwriting and eligibility standards to promote sustainable homeownership. The result of many of these changes is reflected in the substantially improved risk profile of our single-family loan acquisitions since 2009.

In 2016, we continued to implement a number of changes to Desktop Underwriter designed to help originate mortgages with increased certainty, efficiency and lower costs, including making new verification tools available to lenders. As part of our most recent update in September 2016, we incorporated trended credit data into Desktop Underwriter. Trended credit data refers to additional historical information on a borrower’s use of revolving credit accounts, including the balance, scheduled payments and actual payments made on these accounts. Incorporating trended credit data is expected to improve the accuracy of Desktop Underwriter’s credit risk assessment and benefit borrowers who regularly pay down their revolving debt. The September 2016 update to Desktop Underwriter also added the ability to underwrite loans where the borrower does not have a credit score, automating what was previously a manual process for lenders.

We also began offering third-party validation of borrower income data through Desktop Underwriter in October 2016, and plan to expand this validation service to borrower asset and employment data in December 2016. We also plan to update Desktop Underwriter and our Selling Guide in December 2016 to offer a property inspection waiver for certain refinance transactions that meet specified eligibility criteria, including a requirement that a prior appraisal for the subject property associated with one of the borrowers for the refinance must already be in Fannie Mae’s Uniform Collateral Data Portal^®. The majority of our loan acquisitions will continue to require an appraisal to establish market value.

⁽²⁾  The aggregate estimated mark-to-market LTV ratio is based on the unpaid principal balance of the loans as of the end of the period divided by the estimated current value of the properties, which we calculate using an internal valuation model that estimates periodic changes in home value.

⁽⁴⁾  The serious delinquency rates for loans acquired in more recent years will be higher after the loans have aged, but we do not expect them to approach the levels of the September 30, 2016 serious delinquency rates of loans acquired in 2005 through 2008.

⁽⁵⁾  HARP loans, which we began to acquire in 2009, have LTV ratios at origination in excess of 80%.

⁽⁶⁾  Other Refi Plus loans, which we began to acquire in 2009, includes all other Refi Plus loans that are not HARP loans.

Beginning with loans delivered in 2013, and in conjunction with our representation and warranty framework described below, we have made changes in our quality control process that move the primary focus of our quality control review from the time a loan defaults to shortly after the loan is delivered to us. We have implemented new tools to help identify loans delivered to us that may not have met our underwriting or eligibility guidelines and use these tools to help select discretionary samples of performing loans for quality control review shortly after delivery. We also select random samples of performing loans for quality control review shortly after delivery. Our quality control includes reviewing and recording underwriting defects noted in the file and determining if the loan met our underwriting and eligibility guidelines. We also use these reviews to provide lenders with earlier feedback on underwriting defects.

We derive an eligibility defect rate from our random reviews, which represents the proportion of loans in the sample population with underwriting defects that would make them potentially ineligible for delivery to us. The eligibility defect rate does not necessarily indicate how well the loans will ultimately perform. Instead, we use the eligibility defect rate to estimate the percentage of loans we acquired that potentially had a significant error in the underwriting process. As of September 30, 2016, the eligibility defect rate for our single-family non-Refi Plus loan acquisitions made during the twelve months ended January 2016 was 0.61%. We continue to work with lenders to reduce the number of defects.

If we determine that a mortgage loan did not meet our underwriting or eligibility requirements, loan representations or warranties were violated or a mortgage insurer rescinded coverage, then our mortgage sellers and/or servicers are obligated to either repurchase the loan or foreclosed property, reimburse us for our losses or provide other remedies, unless the loan is eligible for representation and warranty relief under our representation and warranty framework described below. We collectively refer to our demands that mortgage sellers and servicers meet these obligations as repurchase requests. The unpaid principal balance of single-family loans that are subject to a repurchase request has declined significantly since we

46

strengthened our underwriting standards in late 2008 and 2009, implemented changes to our quality control process in 2013 and implemented our representation and warranty framework described below. As of September 30, 2016, we had issued repurchase requests on approximately 0.18% of the $464 billion of unpaid principal balance of single-family loans delivered to us during the twelve months ended February 2016.

Our total outstanding repurchase requests as of September 30, 2016 were $257 million, compared with $696 million as of December 31, 2015. The dollar amounts of our outstanding repurchase requests are based on the unpaid principal balance of the loans underlying the repurchase request, not the actual amount we have requested from the lenders. In some cases, we allow lenders to remit payment equal to our loss, including imputed interest, on the loan after we have disposed of the related REO, which may be substantially less than the unpaid principal balance of the loan. As a result, we expect our actual cash receipts relating to these outstanding repurchase requests to be significantly lower than the unpaid principal balance of the loans. Amounts relating to repurchase requests originating from missing documentation or loan files where a full file review could not be completed are excluded from the total requests outstanding until we receive the missing documentation or loan files and a full underwriting review is completed. If we are unable to resolve our repurchase requests, either through collection or additional remedies, we will not recover the losses we have recognized on the associated loans.

Representation and Warranty Framework

Our representation and warranty framework for single-family mortgage loans delivered on or after January 1, 2013 seeks to provide lenders a higher degree of certainty and clarity regarding their repurchase exposure and liability on future deliveries, as well as consistency around repurchase timelines and remedies. Under the framework, lenders are relieved of underwriting-related repurchase liability for loans that meet specific requirements. For example, a lender would not be required to repurchase a mortgage loan in breach of certain underwriting and eligibility representations and warranties if the borrower has made timely payments for 36 months following the delivery date (or, for Refi Plus loans, including HARP loans, for 12 months following the delivery date), and the loan meets other specified eligibility requirements. For single-family loans delivered on or after July 1, 2014, the 36-month timely payment history requirement was relaxed to permit two instances of 30-day delinquency and to add an alternative path to relief if there is a satisfactory conclusion of a full-file quality control review. Certain representations and warranties are “life of loan” representations and warranties, meaning that no relief from their enforcement is available to lenders regardless of the number of payments made by a borrower or the successful completion of a full-file quality control review. Examples of life of loan representations and warranties include, but are not limited to, a lender’s representation and warranty that it has originated the loan in compliance with applicable laws and that the loan conforms to our charter requirements.

We have continued to revise and clarify lenders’ representation and warranty obligations to us. For example, in October 2016, we announced the following expansion of the representation and warranty relief we offer to lenders:

• Borrower data: When lenders use our data validation service available through Desktop Underwriter, we will provide relief from repurchase obligations relating to borrower data that has been validated by Desktop Underwriter.

• Appraised property value: We will offer lenders relief from repurchase obligations with respect to appraised property value for one-unit single-family loans we acquire through Desktop Underwriter if the appraisal provided in connection with the loan received a qualifying Collateral Underwriter risk score. Collateral Underwriter is an appraisal review tool we made available to lenders at no cost beginning in January 2015.

• Property inspection waiver: For lenders that exercise the property inspection waiver option available on certain eligible refinance transactions and pay the related fee, we will waive representations and warranties with respect to property value, condition and marketability.

We implemented representation and warranty relief for borrower income data in October 2016. We plan to implement representation and warranty relief with respect to borrower asset and employment data and appraised property value, as well as property inspection waivers, in December 2016.

We believe the changes we have made to lenders’ representation and warranty obligations, as well as to our quality control process as described above, have significantly reduced uncertainty surrounding lenders’ repurchase risk relating to loans they deliver to us. We continue to work with FHFA to identify opportunities to provide lenders with more certainty and transparency regarding selling representation and warranty obligations.

As of September 30, 2016, approximately 45% of the outstanding loans in our single-family conventional guaranty book of business were acquired under the representation and warranty framework we implemented in 2013, compared with 38% as of December 31, 2015. Table 25 below displays information regarding the relief status of single-family conventional loans, based on payment history or the satisfactory conclusion of a quality control review, delivered to us under the representation and warranty framework we implemented in 2013.

As of September 30, 2016, approximately 37% of loans acquired under the representation and warranty framework had obtained relief, compared with 19% as of December 31, 2015. The increase in the percentage of loans that have obtained repurchase relief in the first nine months of 2016 was driven by the large number of non-Refi Plus single-family loans purchased in the first nine months of 2013 that have now received representation and warranty relief by meeting the 36-month timely payment history requirement. Providing lenders with relief from repurchasing loans for breaches of certain representations and warranties on loans acquired beginning in 2013 that meet specified eligibility requirements shifts some of the risk of non-compliance with our requirements back to us. However, we believe that we have taken appropriate steps to mitigate this risk, including moving the primary focus of our quality control reviews to shortly after the time the loans are delivered to us. We also retain the right to review any defaulted loans that were not previously reviewed and have not obtained relief, in addition to retaining the right to review all loans for any violations of life of loan representations and warranties.

Transfer of Mortgage Credit Risk

Credit Risk-Sharing Transactions

Our Single-Family business has developed risk-sharing capabilities to transfer portions of our single-family mortgage credit risk to the private market. The goal of these transactions is, to the extent economically sensible, to transfer a portion of the existing mortgage credit risk on a portion of recently acquired loans in our single-family guaranty book of business in order to reduce the economic risk to us and to taxpayers of future borrower defaults. In exchange for taking on a portion of the mortgage credit risk on these loans, we pay investors a premium that effectively reduces the guaranty fee income we earn on the loans. Our primary method of achieving this objective has been through CAS and CIRT transactions. As of September 30, 2016, $594.0 billion in outstanding unpaid principal balance of our single-family loans, or approximately21% of the loans in our single-family conventional guaranty book of business measured by unpaid principal balance were included in a reference pool for a CAS or CIRT transaction. We have also executed other types of risk-sharing transactions in addition to our CAS and CIRT transactions. During the first nine months of 2016, we transferred a significant portion of the mortgage credit risk on single-family mortgages with an unpaid principal balance of over $250 billion at the time of the transactions.

We generally include approximately half of our recent single-family acquisitions in credit risk transfer transactions, as we only target certain types of loan categories for credit risk transfer transactions. Loan categories we have targeted for credit risk transfer transactions generally consist of fixed-rate 30-year single-family conventional loans that meet certain credit performance characteristics, are non-Refi Plus and have LTV ratios between 60% and 97%. These targeted loan categories constituted over half of our loan acquisitions for the twelve months ended October 2015, and over 95% of the loans in these categories that we acquired in the twelve months ended October 2015 were included in a subsequent credit risk transfer transaction. Loans are included in reference pools for credit risk transfer transactions on a lagged basis; typically, about six months to one year after we initially acquire the loans. The portion of our single-family loan acquisitions we include in credit risk transfer transactions can vary from period to period based on market conditions and other factors.

In a CAS transaction, we transfer to investors a portion of the mortgage credit risk associated with losses on a reference pool of mortgage loans. We create a reference pool consisting of recently acquired single-family mortgage loans included in our guaranty book of business. We then create a hypothetical securitization structure with notional credit risk positions, or tranches (that is, first loss, mezzanine and senior) and issue CAS debt related to the first loss and mezzanine risk positions. CAS debt is generally issued with a stated final maturity date of either 10 or 12.5 years from issuance, after which the CAS

48

debt provides no further credit protection with respect to the remaining loans in the reference pool underlying that CAS transaction.

Credit losses on the loans in the reference pool for a CAS transaction are first applied to reduce the outstanding principal balance of the first loss tranche. If credit losses on these loans exceed the outstanding principal balance of the first loss tranche, losses would then be applied to reduce the outstanding principal balance of the mezzanine loss tranche. Because we retain the senior loss tranche in CAS transactions, we would absorb any losses that exceed the outstanding principal balance of both the first loss and mezzanine loss tranches. The credit protection that is provided by the first loss and mezzanine loss tranches is expected to absorb all of the losses we estimate would be incurred on these loans in a stressed credit environment, such as a severe or prolonged economic downturn. Our initial CAS transactions sold only a portion of the mezzanine loss tranche to investors. We began to sell a portion of the first loss tranche to investors in 2016. Table 26 below identifies the loss positions we have transferred to investors in CAS and CIRT transactions.

Beginning in 2016, we recognize CAS debt we issue to investors at amortized cost as “Debt of Fannie Mae” in our condensed consolidated balance sheets. CAS debt we issued prior to 2016 is recognized at fair value as “Debt of Fannie Mae” in our condensed consolidated balance sheets. The principal balance of CAS debt decreases as a result of credit losses on loans in the related reference pool. These write downs of the principal balance reduce the total amount of payments we are obligated to make to investors on the CAS debt. We have recognized minimal credit losses on the loans in reference pools underlying CAS issuances to date primarily because the loans were acquired in recent years, after we implemented improvements in our credit underwriting practices, and because recent macroeconomic factors such as unemployment rates and home prices have been favorable.

CIRT deals are insurance transactions whereby we obtain actual loss coverage on pools of loans either directly from an insurance provider that retains the risk, or from an insurance provider that simultaneously cedes all of its risk to one or more reinsurers. CIRT deals are structured so that we retain an aggregate amount of initial losses on the loans in the pool, typically 0.5% of the pool unpaid principal balance at the effective date of the coverage, before the insurance layer, typically 2.5% of the pool unpaid principal balance at the effective date of the coverage, attaches. We currently retain the risk of any remaining losses above the insurance layer. The insurance layer typically provides coverage for losses on the pool that are likely to occur only in a stressed economic environment. Insurance benefits are received after the underlying property has been liquidated and all applicable proceeds, including private mortgage insurance benefits, have been applied to the loss. CIRT transactions completed to date have been written for ten-year terms. A portion of the insurers’ or reinsurers’ obligations is collateralized with highly-rated liquid assets held in a trust account. The required amount of collateral is initially determined according to the ratings of such insurer or reinsurer. There are contractual provisions that require additional collateral to be posted in the event of adverse developments with the counterparty, such as a ratings downgrade. We make premium payments on CIRT deals that we recognize in “Other expenses, net” in our condensed consolidated statements of operations and comprehensive income.

__________

⁽¹⁾  Includes $18.0 billion outstanding for the loss tranches transferred to third parties as of September 30, 2016.

⁽²⁾  For CIRT transactions, “reference pool” reflects a pool of covered loans.

In October 2016, we announced a new pilot front-end CIRT transaction. In contrast to our previous CIRT transactions, in which we obtained credit risk transfer insurance coverage on single-family loans we had previously acquired, in this front-end CIRT structure, the insurance coverage is committed prior to our acquisition of the covered loans and therefore is effective as soon as the loans are acquired. This pilot transaction will shift a portion of the credit risk on pools of single-family loans to a group of affiliates of our mortgage insurer counterparties. We plan to continue to offer our traditional CIRT transactions that cover existing single-family loans in our portfolio.

We intend to continue to engage in regular CAS and CIRT transactions on an ongoing basis, subject to market conditions. FHFA’s 2016 conservatorship scorecard noted that, because Fannie Mae and Freddie Mac’s single-family credit risk transfers have evolved into a core business practice, it is FHFA’s current expectation that single-family credit risk transfers will continue to be an ongoing conservatorship requirement. Accordingly, FHFA’s 2016 conservatorship scorecard includes several objectives relating to our single-family credit risk transfer transactions.

Although we have designed our CAS and CIRT transactions to mitigate some of our potential future credit losses, they are not designed to shield us from all losses because, as shown in Table 26 above, we retain a portion of the risk of future credit losses on loans covered by CAS and CIRT transactions, including all or at least half of the first loss positions and all of the senior loss positions. We have structured the transactions this way because we believe the cost of transferring most of the first loss and the senior loss positions generally exceeds the benefit we would receive from such transfers. In addition, the credit risk transfer market is relatively new, and it is uncertain if there will be adequate demand for these products over the long term to meet our goals for these transactions.

Single-Family Portfolio Diversification and Monitoring

Diversification within our single-family mortgage credit book of business by product type, loan characteristics and geography is an important factor that influences credit quality and performance and may reduce our credit risk. We monitor various loan attributes, in conjunction with housing market and economic conditions, to determine if our pricing, eligibility and

50

underwriting criteria accurately reflect the risk associated with loans we acquire or guarantee. In some cases, we may decide to significantly reduce our participation in riskier loan product categories. We also review the payment performance of loans in order to help identify potential problem loans early in the delinquency cycle and to guide the development of our loss mitigation strategies. For additional information on key loan attributes, see “MD&A—Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management—Single-Family Portfolio Diversification and Monitoring” in our 2015 Form 10-K.

Credit Profile Summary

Overview

Our acquisitions in the first nine months of 2016 continued to have a strong credit profile with a weighted average original LTV ratio of 74% and a weighted average FICO credit score at origination of 749. The credit profile of our future acquisitions will depend on many factors, including: our future guaranty fee pricing and any impact of that pricing on the volume and mix of loans we acquire; our future eligibility standards and those of mortgage insurers, FHA and VA; the percentage of loan originations representing refinancings; changes in interest rates; our future objectives and activities in support of those objectives, including actions we may take to reach additional underserved creditworthy borrowers; government policy; market and competitive conditions; and the volume and characteristics of HARP and high LTV refinance loans we acquire in the future. We expect the ultimate performance of all our loans will be affected by borrower behavior, public policy and macroeconomic trends, including unemployment, the economy and home prices. In addition, if lender customers retain more of the higher-quality loans they originate, it could negatively affect the credit profile of our new single-family acquisitions. We discuss our efforts to increase access to mortgage credit for creditworthy borrowers in “Executive Summary—Single-Family Guaranty Book of Business—Providing Access to Credit Opportunities for Creditworthy Borrowers.”

HARP and Refi Plus Loans

Since 2009, we have offered HARP under our Refi Plus initiative, which was designed to expand refinancing opportunities for borrowers who may otherwise be unable to refinance their mortgage loans due to a decline in home values. HARP offers refinancing flexibility to eligible borrowers who are current on their loans and whose loans are owned or guaranteed by us and meet certain additional criteria. Under HARP, we allow our borrowers who have mortgage loans that have note dates prior to June 2009 with current LTV ratios greater than 80% to refinance their mortgages without obtaining new mortgage insurance in excess of what is already in place. Accordingly, HARP loans have LTV ratios at origination in excess of 80%. HARP loans cannot (1) be an adjustable-rate mortgage loan, if the initial fixed period is less than five years; (2) have an interest only feature, which permits the payment of interest without a payment of principal; (3) be a balloon mortgage loan; or (4) have the potential for negative amortization.

The loans we acquire under HARP have higher LTV ratios than we would otherwise permit, greater than 100% in some cases. Since 2012, we have acquired HARP loans with LTV ratios greater than 125% for fixed-rate loans of eligible borrowers. In addition to the high LTV ratios that characterize HARP loans, some borrowers for HARP and Refi Plus loans may also have lower FICO credit scores and may provide less documentation than we would otherwise require. As of September 30, 2016, HARP loans, which constituted 9% of our single-family book of business, had a weighted average FICO credit score at origination of 727 compared with 745 for loans in our single-family book of business overall.

54

Loans we acquire under Refi Plus and HARP represent refinancings of loans that are already in our guaranty book of business. The credit risk associated with the newly acquired loans essentially replaces the credit risk on the loans that we already held prior to the refinancing. These loans have higher risk profiles and higher serious delinquency rates than the other loans we have acquired since the beginning of 2009. However, we expect these loans will perform better than the loans they replace because HARP and Refi Plus loans should either reduce the borrowers’ monthly payments or provide more stable terms than the borrowers’ old loans (for example, by refinancing into a mortgage with a fixed interest rate instead of an adjustable rate). HARP loans constituted approximately 1% of our total single-family acquisitions in the first nine months of 2016, compared with approximately 2% of total single-family acquisitions in the first nine months of 2015. We expect the volume of refinancings under HARP to continue to remain a small percentage of our acquisitions between now and the program’s expiration, due to the small population of borrowers with loans that have high LTV ratios who are willing to refinance and would benefit from refinancing.

For information on the serious delinquency rates and current mark-to-market LTV ratios as of September 30, 2016 of single-family loans we acquired under HARP and Refi Plus, compared with other single-family loans we have acquired, see “Table 24: Selected Credit Characteristics of Single-Family Conventional Guaranty Book of Business, by Acquisition Period.”

In August 2016, FHFA directed us and Freddie Mac to implement a new high LTV refinance offering aimed at borrowers who are making their mortgage payments on time but whose LTV ratio exceeds the maximum allowed for our standard refinance products. Unlike HARP, the new high LTV refinance offering will not be limited to mortgage loans made prior to June 2009; however, existing Refi Plus (including HARP) mortgage loans will not be eligible for the offering. As with HARP, borrowers eligible for the offering generally will not be subject to a minimum credit score and there generally will be no maximum debt-to-income ratio or maximum LTV ratio. Borrower eligibility requirements will include being current on their mortgage payments and not having any 30-day delinquencies within the past six months and no more than one 30-day delinquency in the past twelve months. This new high LTV refinance offering is scheduled to be available beginning in October 2017. To ensure that high LTV borrowers who are eligible for HARP will not be without a refinance option while the new refinance offering is being implemented, FHFA also directed us and Freddie Mac to extend the HARP sunset date from December 31, 2016 to September 30, 2017. We have also extended the end date of our Refi Plus initiative to September 30, 2017.

Alt-A Loans

We classify certain loans as Alt-A so that we can discuss our exposure to Alt-A loans in this Form 10-Q and elsewhere. However, there is no universally accepted definition of Alt-A loans. Our single-family conventional guaranty book of business includes loans with some features that are similar to Alt-A loans that we have not classified as Alt-A because they do not meet our classification criteria.

We do not rely solely on our classifications of loans as Alt-A to evaluate the credit risk exposure relating to these loans in our single-family conventional guaranty book of business. For more information about the credit risk characteristics of loans in our single-family guaranty book of business, see “Table 27: Risk Characteristics of Single-Family Conventional Business Volume and Guaranty Book of Business,” “Note 3, Mortgage Loans” and “Note 13, Concentrations of Credit Risk.”

Our exposure to Alt-A loans included in our single-family conventional guaranty book of business, based on the classification criteria described in this section, does not include (1) our investments in private-label mortgage-related securities backed by Alt-A loans or (2) resecuritizations, or wraps, of private-label mortgage-related securities backed by Alt-A mortgage loans that we have guaranteed. See “Note 5, Investments in Securities” for more information on our exposure to private label mortgage-related securities backed by Alt-A loans.

We have classified a mortgage loan as Alt-A if and only if the lender that delivered the loan to us classified the loan as Alt-A, based on documentation or other features. The unpaid principal balance of Alt-A loans included in our single-family conventional guaranty book of business of $90.8 billion as of September 30, 2016, represented approximately 3% of our single-family conventional guaranty book of business. Because we discontinued the purchase of newly originated Alt-A loans in 2009, except for those that represent the refinancing of a loan we acquired prior to 2009, we expect our acquisitions of Alt-A mortgage loans to continue to be minimal in future periods and the percentage of the book of business attributable to Alt-A to continue to decrease over time.

See “MD&A—Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management—Single-Family Portfolio Diversification and Monitoring” in our 2015 Form 10-K for a discussion of other types of loans, including jumbo conforming loans, high balance loans, reverse mortgages and mortgages with rate resets.

Problem Loan Management

Our problem loan management strategies are primarily focused on reducing defaults to avoid losses that would otherwise occur and pursuing foreclosure alternatives to attempt to minimize the severity of the losses we incur. If a borrower does not

55

make required payments, or is in jeopardy of not making payments, we work with the servicers of our loans to offer workout solutions to minimize the likelihood of foreclosure as well as the severity of loss. Our loan workouts reflect our various types of home retention solutions, including loan modifications, repayment plans and forbearances, and foreclosure alternatives, including short sales and deeds-in-lieu of foreclosure. When appropriate, we seek to move to foreclosure expeditiously. See “MD&A—Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management—Problem Loan Management” in our 2015 Form 10-K for a discussion of our work with mortgage servicers to implement our foreclosure prevention initiatives.

FHFA’s 2016 conservatorship scorecard includes objectives relating to reducing the number of our severely aged delinquent loans, including through nonperforming loan sales. During the first nine months of 2016, we sold approximately 20,300 nonperforming loans with an aggregate unpaid principal balance of $3.8 billion. As of September 30, 2016, we had sold a total of approximately 30,700 nonperforming loans with an aggregate unpaid principal balance of $5.9 billion. We plan to complete additional nonperforming loan sales in the future.

In the following section, we present statistics on our problem loans, describe efforts undertaken to manage these loans and prevent foreclosures, and provide metrics regarding the performance of our loan workout activities. Unless otherwise noted, single-family delinquency data is calculated based on number of loans. We include single-family conventional loans that we own and those that back Fannie Mae MBS in the calculation of the single-family delinquency rate. Seriously delinquent loans are loans that are 90 days or more past due or in the foreclosure process. Percentage of book outstanding calculations are based on the unpaid principal balance of loans for each category divided by the unpaid principal balance of our total single-family guaranty book of business for which we have detailed loan-level information.

Our single-family serious delinquency rate has decreased each quarter since the first quarter of 2010 and is expected to continue to decrease. The decrease in our serious delinquency rate is primarily the result of home retention solutions, foreclosure alternatives and completed foreclosures, improved loan payment performance and our acquisition of loans with

56

stronger credit profiles since the beginning of 2009. Loans we acquired since 2009 comprised 87% of our single-family guaranty book of business and had a serious delinquency rate of 0.33% as of September 30, 2016. In recent periods, nonperforming loan sales have also contributed to the decrease in our serious delinquency rate.

Our single-family serious delinquency rate and the period of time that loans remain seriously delinquent continue to be negatively impacted by the length of time required to complete a foreclosure in some states. Longer foreclosure timelines result in these loans remaining in our book of business for a longer time, which has caused our serious delinquency rate to decrease more slowly in the last few years than it would have if the pace of foreclosures had been faster. The slow pace of foreclosures in certain areas of the country has negatively affected our single-family serious delinquency rates, foreclosure timelines and financial results, and may continue to do so. Other factors such as the pace of loan modifications, the timing and volume of future nonperforming loan sales we make, servicer performance, changes in home prices, unemployment levels and other macroeconomic conditions also influence serious delinquency rates.

Certain higher-risk loan categories, such as Alt-A loans and loans with higher mark-to-market LTV ratios, and our 2005 through 2008 loan vintages continue to exhibit higher than average delinquency rates and/or account for a higher share of our credit losses. Our 2005 to 2008 loan vintages represented approximately 45% of the loans added to our seriously delinquent loan population during the first nine months of 2016, and 53% of total seriously delinquent loans as of September 30, 2016. In addition, loans in certain states such as Florida, New Jersey and New York have exhibited higher than average delinquency rates and/or account for a higher share of our credit losses.

57

We also include information for our loans in California, as this state accounts for a large share of our single-family conventional guaranty book of business. The reported categories are not mutually exclusive.

__________

⁽¹⁾  Repayment plans reflect only those plans associated with loans that were 60 days or more delinquent. Forbearances reflect loans that were 90 days or more delinquent.

The volume of home retention solutions completed in the first nine months of 2016 decreased compared with the first nine months of 2015, primarily due to a decline in the number of delinquent loans in the first nine months of 2016, compared with the first nine months of 2015.

We continue to work with our servicers to implement our home retention and foreclosure prevention initiatives. Our approach to workouts continues to focus on the large number of borrowers facing financial hardships. Accordingly, the vast majority of loan modifications we have completed since 2009 have been concentrated on deferring or lowering the borrowers’ monthly mortgage payments to allow borrowers to work through their hardships.

Our loan modifications can include a reduction in the borrower’s interest rate that is fixed for an initial period and may be followed by one or more annual interest rate increases. The majority of these rate reset modifications are performing loans that were modified under HAMP^® and have fixed interest rates for an initial five-year period followed by annual interest rate increases, of up to one percent per year, until the mortgage rate reaches the prevailing market rate at the time of modification. The outstanding unpaid principal balance of rate reset modifications in our guaranty book of business was $67.8 billion as of September 30, 2016. During the first nine months of 2016, approximately 55% of these modified loans experienced an interest rate reset to a weighted average interest rate of 3.73%. In anticipation of potential financial hardship related to interest rate increases, we have directed servicers to evaluate rate reset modifications for a re-modification if the loan is at imminent risk of default and the borrower requests a loan modification or if the loan becomes 60 days delinquent within the first 12 months after an interest rate adjustment. Additionally, for borrowers with HAMP modifications we extended “pay for performance” incentives, in the form of principal curtailment, to encourage borrowers to stay current on their mortgages after the initial interest rate reset and to reduce their monthly payments in cases where the borrower chooses to re-amortize their unpaid principal balance following receipt of the incentive. In May 2015, FHFA announced the extension of the ending date for HAMP to December 31, 2016. See “MD&A—Risk Management—Credit Risk Management—Single-Family Mortgage Credit Risk Management—Credit Profile Summary—Mortgage Products with Rate Resets” in our 2015 Form 10-K for additional information on the timing of these initial interest rate resets.

59

As directed by FHFA, in April 2016, we announced a new principal reduction modification program. This program is a targeted effort to assist seriously delinquent borrowers with negative equity in their homes avoid foreclosure and help improve the stability of communities that have not yet recovered from the housing crisis. The program offers principal reduction to borrowers who, as of March 1, 2016, met the specific requirements set forth in the program, including the following: the borrower was at least 90 days delinquent, had a loan with an unpaid principal balance of $250,000 or less, and was an owner-occupant. In addition, at the time of evaluation, the loan must have a post-modification mark-to-market LTV ratio of more than 115%. The amount of principal reduction we will provide to a borrower who meets the requirements of the program is the lesser of: (1) the amount that would create a post-modification mark-to-market LTV ratio of 115%; or (2) 30% of the gross post-modified unpaid principal balance of the loan. We estimate that approximately 22,000 loans in our single-family guaranty book of business as of March 31, 2016 were eligible for the principal reduction modification program. We expect trial modifications under this program to continue through the first quarter of 2017, converting to permanent modifications between now and the second quarter of 2017.

REO Management

Foreclosure and REO activity affect the amount of credit losses we realize in a given period. Table 31 displays our foreclosure activity by region. Regional REO acquisition and charge-off trends generally follow a pattern that is similar to, but lags, that of regional delinquency trends.

⁽³⁾  Estimated based on the annualized total number of properties acquired through foreclosure or deeds-in-lieu of foreclosure as a percentage of the total number of loans in our single-family guaranty book of business as of the end of each respective period.

The continued decrease in the number of our seriously delinquent single-family loans resulted in a reduction in the number of REO acquisitions in the first nine months of 2016 compared with the first nine months of 2015.

In some cases, we engage in third party sales at foreclosure, which allow us to avoid maintenance and other REO expenses we would have incurred had we acquired the property.

We continue to manage our REO inventory to appropriately control costs and maximize sales proceeds. However, we are unable to market and sell a large portion of our inventory, primarily due to occupancy and state or local redemption or confirmation periods, which extends the amount of time it takes to bring our properties to a marketable state and eventually dispose of them. This results in higher foreclosed property expenses, which include costs related to maintaining the property and ensuring that the property is vacant. As of September 30, 2016, approximately 38% of our REO properties were unable to

60

be marketed, 26% of our REO properties were available for sale, 18% of our REO properties were pending sale settlement and 18% of our REO properties were pending appraisals and being prepared to be listed for sale.

Multifamily Mortgage Credit Risk Management

The credit risk profile of our multifamily mortgage credit book of business is influenced by the structure of the financing, the type and location of the property, the condition and value of the property, the financial strength of the borrower, market and sub-market trends and growth, and the current and anticipated cash flows from the property. These and other factors affect both the amount of expected credit loss on a given loan and the sensitivity of that loss to changes in the economic environment. We provide information on our multifamily credit-related income and credit losses in “Business Segment Results—Multifamily Business Results.”

Multifamily Acquisition Policy and Underwriting Standards

Our Multifamily business is responsible for pricing and managing the credit risk on multifamily mortgage loans we purchase and on Fannie Mae MBS backed by multifamily loans (whether held in our retained mortgage portfolio or held by third parties), with oversight from our Enterprise Risk Management division. Our primary multifamily delivery channel is the Delegated Underwriting and Servicing, or DUS^®, program, which consists of large financial institutions and independent mortgage lenders. Multifamily loans that we purchase or that back Fannie Mae MBS are underwritten by a Fannie Mae-approved lender and may be subject to our underwriting review prior to closing, depending on the product type, loan size, market and/or other factors. Loans delivered to us by DUS lenders and their affiliates represented 97% of our multifamily guaranty book of business as of September 30, 2016 and December 31, 2015.

We use credit enhancement arrangements, primarily lender risk-sharing, for our multifamily loans. Lenders in the DUS program typically share in loan-level credit losses in one of two ways: (1) they bear losses up to the first 5% of the unpaid principal balance of the loan and share in remaining losses up to a prescribed limit; or (2) they share up to one-third of the losses on a pro rata basis with us. Non-DUS lenders typically share or absorb losses based on a negotiated percentage of the loan or the pool balance.

As of September 30, 2016, 93% of the unpaid principal balance of loans in our multifamily guaranty book of business had lender risk-sharing. Our maximum potential loss recovery from lenders under current risk-sharing agreements represented over 20% of the unpaid principal balance of our multifamily guaranty book of business as of September 30, 2016. These risk-sharing agreements not only transfer credit risk, but also better align our interests with those of the lenders.

At the time of our purchase or guarantee of multifamily mortgage loans, we and our lenders rely on sound underwriting standards, which generally include third-party appraisals and cash flow analysis. Our standards for multifamily loans specify maximum original LTV ratio and minimum original debt service coverage ratio (“DSCR”) values that vary based on loan characteristics. Our experience has been that original LTV ratio and DSCR values have been reliable indicators of future credit performance. At underwriting, we evaluate the DSCR based on both actual and underwritten debt service payments. The original DSCR is calculated using the underwritten debt service payments for the loan, rather than the actual debt service payments, which, depending on the interest rate of the loan and loan structure, may result in a more conservative estimate of the debt service payments.

Table 32 displays original LTV ratio and DSCR metrics for our multifamily guaranty book of business.

Table 32: Multifamily Guaranty Book of Business Key Risk Characteristics

	As of
	September 30, 2016			December 31, 2015			September 30, 2015
Weighted average original LTV ratio		67	%		66	%		66	%
Original LTV ratio greater than 80%		2			3			3
Original DSCR less than or equal to 1.10		13			11			10

The percentage of our book of business with an original DSCR less than or equal to 1.10 has increased to 13% as of September 30, 2016, driven by an increase in business volume funded with adjustable-rate mortgages and with fixed-rate mortgages with different loan structures, which are underwritten at higher interest rates than the actual rates on those loans.

Multifamily Portfolio Diversification and Monitoring

Diversification within our multifamily mortgage credit book of business by geographic concentration, term to maturity, interest rate structure, borrower concentration and loan size, as well as credit enhancement coverage, are important factors that influence credit performance and help reduce our credit risk.

We and our lenders monitor the performance and risk characteristics of our multifamily loans and the underlying properties on an ongoing basis throughout the loan term at the asset and portfolio level. We closely monitor loans with an estimated current DSCR below 1.0, as that is an indicator of heightened default risk. The percentage of loans in our multifamily guaranty book of business, calculated based on unpaid principal balance, with a current DSCR less than 1.0 was approximately 2% as of September 30, 2016 and December 31, 2015. Our estimates of current DSCRs are based on the latest available income information for these properties. Although we use the most recently available results from our multifamily borrowers, there is a lag in reporting, which typically can range from 3 to 6 months but in some cases may be longer.

Multifamily Problem Loan Management and Foreclosure Prevention

We periodically refine our underwriting standards in response to market conditions and implement proactive portfolio management and monitoring which are each designed to keep credit losses and delinquencies to a low level relative to our multifamily guaranty book of business. The multifamily serious delinquency rate was 0.07% as of September 30, 2016 and December 31, 2015. We classify multifamily loans as seriously delinquent when payment is 60 days or more past due.

REO Management

The number of multifamily foreclosed properties held for sale increased from 12 properties with a carrying value of $91 million as of December 31, 2015 to 24 properties with a carrying value of $134 million as of September 30, 2016. Despite the increase in the number of properties, we expect the level of foreclosure activity to remain low as the national multifamily sector continues to exhibit stability.

Institutional Counterparty Credit Risk Management

Institutional counterparty credit risk is the risk that our institutional counterparties may fail to fulfill their contractual obligations to us. Defaults by a counterparty with significant obligations to us could result in significant financial losses to us.

See “MD&A—Risk Management—Credit Risk Management—Institutional Counterparty Credit Risk Management” and “Risk Factors” in our 2015 Form 10-K for additional information about institutional counterparty risk, including counterparty risk we face from mortgage originators, investors and dealers, from debt security dealers, from document custodians and from mortgage fraud.

Mortgage Sellers and Servicers

One of our primary exposures to institutional counterparty risk is with mortgage servicers that service the loans we hold in our retained mortgage portfolio or that back our Fannie Mae MBS, as well as mortgage sellers and servicers that are obligated to repurchase loans from us or reimburse us for losses in certain circumstances. We rely on mortgage servicers to meet our servicing standards and fulfill their servicing obligations. We also rely on mortgage sellers and servicers to fulfill their repurchase obligations.

Our five largest single-family mortgage servicers, including their affiliates, serviced approximately 40% of our single-family guaranty book of business as of September 30, 2016, compared with approximately 44% as of December 31, 2015. Our largest mortgage servicer is Wells Fargo Bank, N.A., which, together with its affiliates, serviced approximately 17% of our single-family guaranty book of business as of September 30, 2016 and December 31, 2015.

Our five largest multifamily mortgage servicers, including their affiliates, serviced approximately 46% of our multifamily guaranty book of business as of September 30, 2016, compared with approximately 45% as of December 31, 2015. Wells Fargo Bank, N.A. and Walker & Dunlop, LLC each serviced over 10% of our multifamily guaranty book of business as of September 30, 2016 and December 31, 2015.

A large portion of our single-family guaranty book is serviced by non-depository servicers. As of September 30, 2016, 18% of our total single-family guaranty book of business, including 57% of our delinquent single-family loans, was serviced by our five largest non-depository servicers, compared with 19% of our total single-family guaranty book of business, including 60% of our delinquent single-family loans, as of December 31, 2015. Compared with depository financial institutions, non-depository servicers pose additional risks to us because non-depository servicers may have a greater reliance on third-party sources of liquidity and may, in the event of significant increases in delinquent loan volumes, have less financial capacity to advance funds on our behalf or satisfy repurchase requests or compensatory fee obligations. In addition, regulatory bodies

62

have been reviewing the activities of some of our largest non-depository servicers. See “Risk Factors” in our 2015 Form 10-K for a discussion of the risks of our reliance on servicers.

Our five largest single-family mortgage sellers, including their affiliates, accounted for approximately 28% of our single-family business acquisition volume in the first nine months of 2016, compared with approximately 29% in the first nine months of 2015. Our largest mortgage seller is Wells Fargo Bank, N.A., which, together with its affiliates, accounted for approximately 13% of our single-family business acquisition volume in the first nine months of 2016 and 2015. We acquire a portion of our business volume directly from non-depository and smaller depository financial institutions that may not have the same financial strength or operational capacity as our largest mortgage seller counterparties. We could be required to absorb losses on defaulted loans that a failed mortgage seller is obligated to repurchase from us if we determine there was an underwriting eligibility breach.

Repurchase Requests

Mortgage sellers and servicers may not meet the terms of their repurchase obligations, and we may be unable to recover on all outstanding loan repurchase obligations resulting from their breaches of contractual obligations, which may have an adverse effect on our results of operations and financial condition. See “Single-Family Mortgage Credit Risk Management—Single-Family Acquisition and Servicing Policies and Underwriting and Servicing Standards” for additional information regarding repurchase requests and the balance of our outstanding repurchase requests as of September 30, 2016.

Credit Guarantors

We use various types of credit guarantors to manage our mortgage credit risk, including mortgage insurers, financial guarantors, reinsurers and multifamily lenders with risk sharing.

Mortgage Insurers

We are generally required, pursuant to our charter, to obtain credit enhancements on single-family conventional mortgage loans that we purchase or securitize with LTV ratios over 80% at the time of purchase. We use several types of credit enhancements to manage our single-family mortgage credit risk, including primary and pool mortgage insurance coverage. Table 33 displays our risk in force for mortgage insurance coverage on single-family loans in our guaranty book of business and our insurance in force for our mortgage insurer counterparties, excluding insurance coverage provided by federal government entities and credit insurance obtained through CIRT deals. The table includes our top ten mortgage insurer counterparties, which provided over 99% of our total mortgage insurance coverage on single-family loans in our guaranty book of business as of September 30, 2016 and December 31, 2015. In addition, for our mortgage insurer counterparties not approved to write new business, we have provided the percentage of their claims payments the counterparties are currently deferring based on the direction of their state regulators, referred to as their deferred payment obligation. As of September 30, 2016 and December 31, 2015, approximately 1% of our total risk in force mortgage insurance coverage was pool insurance. In addition, approximately 1% and 2% of our total insurance in force mortgage insurance coverage was pool insurance as of September 30, 2016 and December 31, 2015.

__________

⁽¹⁾  Risk in force is generally the maximum potential loss recovery under the applicable mortgage insurance policies in force and is based on the loan level insurance coverage percentage and, if applicable, any aggregate pool loss limit, as specified in the policy. 

⁽²⁾  Insurance in force represents the unpaid principal balance of single-family loans in our guaranty book of business covered under the applicable mortgage insurance policies.

⁽³⁾  Deferred payment obligation represents the percentage of cash payments on policyholder claims being deferred as directed by the insurer’s respective regulator in the state of domicile as of September 30, 2016.

⁽⁴⁾  Insurance coverage amounts provided for each counterparty may include coverage provided by consolidated affiliates and subsidiaries of the counterparty.

⁽⁵⁾  “Approved” mortgage insurers are counterparties approved to write new insurance with us. “Not approved” mortgage insurers are counterparties that are no longer approved to write new insurance with us.

⁽⁶⁾  These mortgage insurers are under various forms of supervised control by their state regulators and are in run-off.

⁽⁷⁾  Effective June 10, 2016, PMI increased its cash payments on policyholder claims from 70% to 71.5%, and subsequently paid sufficient amounts of its outstanding deferred payment obligations to bring payment on those claims to 71.5%. It is uncertain whether PMI will be permitted in the future to pay any remaining deferred policyholder claims or increase or decrease the amount of cash it pays on claims.

We manage our exposure to mortgage insurers by maintaining eligibility requirements that an insurer must meet to be a qualified mortgage insurer. We require a certification and supporting documentation annually from each mortgage insurer and perform periodic reviews of mortgage insurers to confirm compliance with eligibility requirements and to evaluate their management, control and underwriting practices. Our monitoring of the mortgage insurers includes in-depth financial reviews and analyses of the insurers’ portfolios and capital adequacy under hypothetical stress scenarios.

64

Although the financial condition of our primary mortgage insurer counterparties currently approved to write new business has improved in recent years, there is still a risk that these counterparties may fail to fulfill their obligations to pay our claims under insurance policies. In addition, as shown in “Table 33: Mortgage Insurance Coverage,” three of our top mortgage insurer counterparties—PMI Mortgage Insurance Co., Republic Mortgage Insurance Company and Triad Guaranty Insurance Corporation—are currently under various forms of supervised control by their state regulators and are in run-off, which increases the risk that these counterparties will pay claims only in part or fail to pay claims at all under existing insurance policies. See “Risk Factors” in our 2015 Form 10-K for a discussion of the risks to our business of claims under our mortgage insurance policies not being paid in full or at all, including the risks associated with our three mortgage insurance counterparties that are in run off.

In August 2016, Arch Capital Group Ltd., the ultimate parent company of Arch Mortgage Insurance Co., announced that it had entered into an agreement to acquire United Guaranty Corporation and AIG United Guaranty Insurance (Asia) Limited from their current owner, American International Group, Inc. United Guaranty Corporation is the ultimate parent company of United Guaranty Residential Insurance Co. The acquisition is subject to regulatory approvals and other closing conditions. In addition, the continued approval of United Guaranty Residential Insurance Co. and its subsidiary United Guaranty Mortgage Indemnity Company as our mortgage insurer counterparties following the acquisition is subject to our review.

When we estimate the credit losses that are inherent in our mortgage loans and under the terms of our guaranty obligations we also consider the recoveries that we will receive on primary mortgage insurance, as mortgage insurance recoveries would reduce the severity of the loss associated with defaulted loans. We evaluate the financial condition of our mortgage insurer counterparties and adjust the contractually due recovery amounts to ensure that only probable losses as of the balance sheet date are included in our loss reserve estimate. As a result, if our assessment of one or more of our mortgage insurer counterparties’ ability to fulfill their respective obligations to us worsens, it could result in an increase in our loss reserves. The amount by which our estimated benefit from mortgage insurance reduced our total loss reserves was $1.5 billion as of September 30, 2016 and $2.3 billion as of December 31, 2015.

When an insured loan held in our retained mortgage portfolio subsequently goes into foreclosure, we charge off the loan, eliminating any previously-recorded loss reserves, and record REO and a mortgage insurance receivable for the claim proceeds deemed probable of recovery, as appropriate. However, if a mortgage insurer rescinds, cancels or denies insurance coverage, the initial receivable becomes due from the mortgage seller or servicer. We had outstanding receivables of $1.0 billion recorded in “Other assets” in our condensed consolidated balance sheets as of September 30, 2016 and $1.2 billion as of December 31, 2015 related to amounts claimed on insured, defaulted loans excluding government insured loans. Of this amount, $135 million as of September 30, 2016 and $241 million as of December 31, 2015 was due from our mortgage sellers or servicers. We assessed the total outstanding receivables for collectibility, and they are recorded net of a valuation allowance of $658 million as of September 30, 2016 and $770 million as of December 31, 2015. The valuation allowance reduces our claim receivable to the amount considered probable of collection as of September 30, 2016 and December 31, 2015.

Financial Guarantors

We are the beneficiary of non-governmental financial guarantees on non-agency securities held in our retained mortgage portfolio and on non-agency securities that have been resecuritized to include a Fannie Mae guaranty and sold to third parties. The total unpaid principal balance of guaranteed non-agency securities in our retained mortgage portfolio was $2.0 billion as of September 30, 2016 and $3.2 billion as of December 31, 2015. See “Note 15, Concentrations of Credit Risk” in our 2015 Form 10-K for a further discussion of our exposure to financial guarantors.

We are also the beneficiary of financial guarantees included in securities issued by Freddie Mac, the federal government and its agencies that totaled $12.0 billion as of September 30, 2016 and $16.7 billion as of December 31, 2015.

Credit Insurance Risk Transfer Counterparties

In a credit insurance risk transfer transaction, we shift a portion of the credit risk on a reference pool of mortgage loans to a panel of credit insurers or reinsurers. A portion of the credit insurers’ or reinsurers’ obligations are collateralized with highly-rated liquid assets held in a trust account. Our credit insurance risk transfer transactions are described in “Single-Family Mortgage Credit Risk Management—Transfer of Mortgage Credit Risk—Credit Risk-Sharing Transactions.”

Multifamily Lenders with Risk Sharing

We enter into risk sharing agreements with lenders pursuant to which the lenders agree to bear all or some portion of the credit losses on the covered loans. Our maximum potential loss recovery from lenders under risk sharing agreements on DUS and non-DUS multifamily loans was $52.2 billion as of September 30, 2016, compared with $46.2 billion as of December 31,

65

2015. As of September 30, 2016, 42% of our maximum potential loss recovery on multifamily loans was from four DUS lenders, compared with 40% as of December 31, 2015.

As noted above in “Multifamily Mortgage Credit Risk Management—Multifamily Acquisition Policy and Underwriting Standards,” our primary multifamily delivery channel is our DUS program, which is comprised of lenders that range from large depositories to independent non-bank financial institutions. As of September 30, 2016 and December 31, 2015, 35% of the unpaid principal balance of loans in our multifamily guaranty book of business serviced by our DUS lenders was from institutions with an external investment grade credit rating or a guaranty from an affiliate with an external investment grade credit rating. Given the recourse nature of the DUS program, the lenders are bound by eligibility standards that dictate, among other items, minimum capital and liquidity levels, and the posting of collateral at a highly rated custodian to secure a portion of the lenders’ future obligations. We actively monitor the financial condition of these lenders to help ensure the level of risk remains within our standards and to ensure required capital levels are maintained and are in alignment with actual and modeled loss projections.

Custodial Depository Institutions

We evaluate our custodial depository institutions to determine whether they are eligible to hold deposits on our behalf based on requirements specified in our Servicing Guide. If a custodial depository institution were to fail while holding remittances of borrower payments of principal and interest due to us in our custodial account, we would be an unsecured creditor of the depository for balances in excess of the deposit insurance protection and might not be able to recover all of the principal and interest payments being held by the depository on our behalf, or there might be a substantial delay in receiving these amounts. If this were to occur, we would be required to replace these amounts with our own funds to make payments that are due to Fannie Mae MBS certificateholders. Accordingly, the insolvency of one of our principal custodial depository counterparties could result in significant financial losses to us. During the month of September 2016, approximately $4.8 billion, or 10%, of our total deposits for single-family payments and approximately $1.0 billion, or 39%, of our total deposits for multifamily payments received and held by these institutions was in excess of the deposit insurance protection limit. These amounts can vary as they are calculated based on individual payments of mortgage borrowers, which requires us to estimate which borrowers are paying their regular principal and interest payments and other types of payments, such as prepayments from refinancing or sales.

A total of $48.2 billion in deposits for single-family payments were received and held by 256 institutions during the month of September 2016 and a total of $31.5 billion in deposits for single-family payments were received and held by 263 institutions during the month of December 2015. Of these total deposits, 90% as of September 30, 2016, were held by institutions rated as investment grade by S&P Global Ratings (“S&P”), “Aaa” by Moody’s Investors Services (“Moody’s”) and “AAA” by Fitch Ratings Limited (“Fitch”), compared with 92% as of December 31, 2015. Our transactions with custodial depository institutions are concentrated. Our six largest custodial depository institutions held 79% of these deposits as of September 30, 2016, compared with 83% as of December 31, 2015.

During the month of September 2016, a total of $2.6 billion in deposits for multifamily payments were received and held by 28 institutions and $3.4 billion in deposits for multifamily payments were received and held by 28 institutions during the month of December 2015. Of these total deposits, 97% as of September 30, 2016, were held by institutions rated as investment grade by S&P, Moody’s and Fitch, compared with 98% as of December 31, 2015. Our transactions with custodial depository institutions are concentrated. Our six largest custodial depository institutions held 88% of these deposits as of September 30, 2016, compared with 95% as of December 31, 2015.

Counterparty Credit Exposure of Investments Held in our Cash and Other Investments Portfolio

Our cash and other investments portfolio consists of cash and cash equivalents, securities purchased under agreements to resell or similar arrangements and U.S. Treasury securities. Our cash and other investment counterparties are primarily financial institutions, including clearing organizations, and the Federal Reserve Bank. As of September 30, 2016 and December 31, 2015, we held $2.0 billion in short-term unsecured deposits with two financial institutions that had a short-term credit rating of A-1 from S&P (or its equivalent), based on the lowest credit rating issued by S&P, Moody’s and Fitch, and no other unsecured positions other than U.S. Treasury securities. See “Liquidity and Capital Management—Liquidity Management—Cash and Other Investments Portfolio” for more detailed information on our cash and other investments portfolio.

Derivative Counterparty Credit Exposure

Our derivative counterparty credit exposure relates principally to interest rate derivative contracts. We are exposed to the risk that a counterparty in a derivative transaction will default on payments due to us, which may require us to seek a replacement derivative from a different counterparty. This replacement may be at a higher cost, or we may be unable to find a suitable

66

replacement. Historically, our risk management derivative transactions have been made pursuant to bilateral contracts with a specific counterparty governed by the terms of an International Swaps and Derivatives Association Inc. master agreement. Pursuant to regulations implementing the Dodd-Frank Act, we are required to submit certain categories of new interest rate swaps to a derivatives clearing organization. We refer to our derivative transactions made pursuant to bilateral contracts as our over-the-counter (“OTC”) derivative transactions and our derivative transactions accepted for clearing by a derivatives clearing organization as our cleared derivative transactions.

We manage our derivative counterparty credit exposure relating to our OTC derivative transactions through enforceable master netting arrangements. These arrangements allow us to net derivative assets and liabilities with the same counterparty. We also manage our derivative counterparty exposure relating to our OTC derivative transactions by requiring counterparties to post collateral, which includes cash, U.S. Treasury securities, agency debt and agency mortgage-related securities.

Our cleared derivative transactions are submitted to a derivatives clearing organization on our behalf through a clearing member of the organization. A contract accepted by a derivatives clearing organization is governed by the terms of the clearing organization’s rules and arrangements between us and the clearing member of the clearing organization. As a result, we are exposed to the institutional credit risk of both the derivatives clearing organization and the member who is acting on our behalf. We manage our credit exposure relating to our cleared derivative transactions through enforceable master netting arrangements. These arrangements allow us to net our exposure to cleared derivatives by clearing organization and by clearing member.

Our institutional credit risk exposure to derivatives clearing organizations and certain of their members may continue to increase in the future if cleared derivative contracts comprise a larger percentage of our derivative instruments. We estimate our exposure to credit loss on derivative instruments by calculating the replacement cost, on a present value basis, to settle at current market prices all outstanding derivative contracts in a net gain position at the counterparty level where the right of legal offset exists.

The fair value of derivatives in a gain position is included in our condensed consolidated balance sheets in “Other assets.” Total exposure represents our exposure to credit loss on derivative instruments less the cash and non-cash collateral posted by our counterparties to us. This does not include collateral held in excess of exposure. Our total exposure was $27 million as of September 30, 2016 and $31 million as of December 31, 2015. The majority of our total exposure as of each date consisted of mortgage insurance contracts accounted for as derivatives.

As of September 30, 2016 and December 31, 2015, we had sixteen counterparties with which we may transact OTC derivative transactions, all of which were subject to enforceable master netting arrangements. We had outstanding notional amounts with all of these counterparties, and the highest concentration by our total outstanding notional amount was approximately 9% as of September 30, 2016 and 7% as of December 31, 2015.

See “Note 9, Derivative Instruments” and “Note 14, Netting Arrangements” for additional information on our derivative contracts as of September 30, 2016 and December 31, 2015.

Market Risk Management, Including Interest Rate Risk Management

We are subject to market risk, which includes interest rate risk, spread risk and liquidity risk. These risks arise from our mortgage asset investments. Interest rate risk is the risk of loss in value or expected future earnings that may result from changes to interest rates. Spread risk or basis risk is the resulting impact of changes in the spread between our mortgage assets and our debt and derivatives we use to hedge our position. Liquidity risk is the risk that we will not be able to meet our funding obligations in a timely manner. We describe our sources of interest rate risk exposure, business risks posed by changes in interest rates, and our strategy for managing interest rate risk and spread risk in “MD&A—Risk Management—Market Risk Management, Including Interest Rate Risk Management” and in “Risk Factors” in both our 2015 Form 10-K and this report.

Measurement of Interest Rate Risk

Below we present two quantitative metrics that provide estimates of our interest rate risk exposure: (1) fair value sensitivity of our net portfolio to changes in interest rate levels and slope of yield curve; and (2) duration gap. Our net portfolio consists of our retained mortgage portfolio assets; cash and other investments portfolio assets; our outstanding debt of Fannie Mae that is used to fund our retained mortgage portfolio assets and cash and other investments portfolio assets; mortgage commitments; and risk management derivatives. Risk management derivatives along with our debt instruments are used to manage interest rate risk.

The metrics presented are calculated using internal models that require standard assumptions regarding interest rates and future prepayments of principal over the remaining life of our securities. These assumptions are derived based on the

67

characteristics of the underlying structure of the securities and historical prepayment rates experienced at specified interest rate levels, taking into account current market conditions, the current mortgage rates of our existing outstanding loans, loan age and other factors. On a continuous basis, management makes judgments about the appropriateness of the risk assessments and will make adjustments as necessary to properly assess our interest rate exposure and manage our interest rate risk. The methodologies used to calculate risk estimates are periodically changed on a prospective basis to reflect improvements in the underlying estimation process.

Interest Rate Sensitivity to Changes in Interest Rate Level and Slope of Yield Curve

Pursuant to a disclosure commitment with FHFA, we disclose on a monthly basis the estimated adverse impact on the fair value of our net portfolio that would result from the following hypothetical situations:

• A 50 basis point shift in interest rates.

• A 25 basis point change in the slope of the yield curve.

In measuring the estimated impact of changes in the level of interest rates, we assume a parallel shift in all maturities of the U.S. LIBOR interest rate swap curve.

In measuring the estimated impact of changes in the slope of the yield curve, we assume a constant 7-year rate and a shift of 16.7 basis points for the 1-year rate and 8.3 basis points for the 30-year rate. We believe the aforementioned interest rate shocks for our monthly disclosures represent moderate movements in interest rates over a one-month period.

Duration Gap

Duration gap measures the price sensitivity of our assets and liabilities in our net portfolio to changes in interest rates by quantifying the difference between the estimated durations of our assets and liabilities. Our duration gap analysis reflects the extent to which the estimated maturity and repricing cash flows for our assets are matched, on average, over time and across interest rate scenarios to those of our liabilities. A positive duration gap indicates that the duration of our assets exceeds the duration of our liabilities. We disclose duration gap on a monthly basis under the caption “Interest Rate Risk Disclosures” in our Monthly Summary, which is available on our website and announced in a press release.

While our goal is to reduce the price sensitivity of our net portfolio to movements in interest rates, various factors can contribute to a duration gap that is either positive or negative. For example, changes in the market environment can increase or decrease the price sensitivity of our mortgage assets relative to the price sensitivity of our liabilities because of prepayment uncertainty associated with our assets. In a declining interest rate environment, prepayment rates tend to accelerate, thereby shortening the duration and average life of the fixed rate mortgage assets we hold in our net portfolio. Conversely, when interest rates increase, prepayment rates generally slow, which extends the duration and average life of our mortgage assets. Our debt and derivative instrument positions are used to manage the interest rate sensitivity of our retained mortgage portfolio and our investments in non-mortgage securities. As a result, the degree to which the interest rate sensitivity of our retained mortgage portfolio and our investments in non-mortgage securities is offset will be dependent upon, among other factors, the mix of funding and other risk management derivative instruments we use at any given point in time.

The market value sensitivities of our net portfolio are a function of both the duration and the convexity of our net portfolio. Duration provides a measure of the price sensitivity of a financial instrument to changes in interest rates while convexity reflects the degree to which the duration of the assets and liabilities in our net portfolio changes in response to a given change in interest rates. We use convexity measures to provide us with information about how quickly and by how much our net portfolio’s duration may change in different interest rate environments. The market value sensitivity of our net portfolio will depend on a number of factors, including the interest rate environment, modeling assumptions and the composition of assets and liabilities in our net portfolio, which vary over time.

Results of Interest Rate Sensitivity Measures

The interest rate risk measures discussed below exclude the impact of changes in the fair value of our guaranty assets and liabilities resulting from changes in interest rates. We exclude our guaranty business from these sensitivity measures based on our current assumption that the guaranty fee income generated from future business activity will largely replace guaranty fee income lost due to mortgage prepayments.

Table 34 displays the pre-tax market value sensitivity of our net portfolio to changes in the level of interest rates and the slope of the yield curve as measured on the last day of each period presented. Table 34 also provides the daily average, minimum, maximum and standard deviation values for duration gap and for the most adverse market value impact on the net portfolio to changes in the level of interest rates and the slope of the yield curve for the three months ended September 30, 2016 and 2015.

68

The sensitivity measures displayed in Table 34, which we disclose on a quarterly basis pursuant to a disclosure commitment with FHFA, are an extension of our monthly sensitivity measures. There are three primary differences between our monthly sensitivity disclosure and the quarterly sensitivity disclosure presented below: (1) the quarterly disclosure is expanded to include the sensitivity results for larger rate level shocks of positive or negative 100 basis points; (2) the monthly disclosure reflects the estimated pre-tax impact on the market value of our net portfolio calculated based on a daily average, while the quarterly disclosure reflects the estimated pre-tax impact calculated based on the estimated financial position of our net portfolio and the market environment as of the last business day of the quarter; and (3) the monthly disclosure shows the most adverse pre-tax impact on the market value of our net portfolio from the hypothetical interest rate shocks, while the quarterly disclosure includes the estimated pre-tax impact of both up and down interest rate shocks.

The market value sensitivity of our net portfolio varies across a range of interest rate shocks depending upon the duration and convexity profile of our net portfolio. Because the effective duration gap of our net portfolio was close to zero months in the periods presented, the convexity exposure was the primary driver of the market value sensitivity as of September 30, 2016. In addition, the convexity exposure may result in similar market value sensitivities for positive and negative interest rate shocks of the same magnitude.

69

A majority of the interest rate risk associated with our mortgage-related securities and loans is hedged with our debt issuances, which include callable debt. We use derivatives to help manage the residual interest rate risk exposure between our assets and liabilities. Derivatives have enabled us to keep our interest rate risk exposure at consistently low levels in a wide range of interest-rate environments. Table 35 displays an example of how derivatives impacted the net market value exposure for a 50 basis point parallel interest rate shock.

IMPACT OF FUTURE ADOPTION OF NEW ACCOUNTING GUIDANCE

We identify and discuss the expected impact on our condensed consolidated financial statements of recently issued accounting guidance in “Note 1, Summary of Significant Accounting Policies.”

FORWARD-LOOKING STATEMENTS

This report includes statements that constitute forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”). In addition, our senior management may from time to time make forward-looking statements orally to analysts, investors, the news media and others. Forward-looking statements often include words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “seek,” “estimate,” “forecast,” “project,” “would,” “should,” “could,” “likely,” “may,” “will” or similar words.

Among the forward-looking statements in this report are statements relating to:

• Our expectation that we will remain profitable on an annual basis for the foreseeable future; however, certain factors, such as changes in interest rates or home prices, could result in significant volatility in our financial results from quarter to quarter or year to year;

• Our expectation that our future financial results also will be affected by a number of other factors, including: our guaranty fee rates; the volume of single-family mortgage originations in the future; the size, composition and quality of our retained mortgage portfolio and guaranty book of business; and economic and housing market conditions;

• Our expectation of volatility from period to period in our financial results from a number of factors, particularly changes in market conditions that result in fluctuations in the estimated fair value of the financial instruments that we mark to market through our earnings;

• Our expectation that we will pay Treasury a senior preferred stock dividend of $3.0 billion for the fourth quarter of 2016 by December 31, 2016;

70

• Our expectation that we will retain only a limited amount of any future net worth because we are required by the dividend provisions of the senior preferred stock and quarterly directives from our conservator to pay Treasury each quarter any dividends declared consisting of the amount, if any, by which our net worth as of the end of the immediately preceding fiscal quarter exceeds an applicable capital reserve amount;

• Our intention to continue to engage in credit risk transfer transactions on an ongoing basis, subject to market conditions;

• Our expectation that, over time, a larger portion of our single-family conventional guaranty book of business will be covered by credit risk transfer transactions;

• Our expectation that our single-family acquisitions will continue to have a strong overall credit risk profile given our current underwriting and eligibility standards and product design;

• Our expectation that incorporating trended credit data into Desktop Underwriter will improve the accuracy of Desktop Underwriter’s credit risk assessment and benefit borrowers who regularly pay down their revolving debt;

• Our plan to expand our third-party validation service to borrower asset and employment data in December 2016;

• Our plan to update Desktop Underwriter and our Selling Guide in December 2016 to offer a property inspection waiver for certain refinance transactions that meet specified eligibility criteria;

• Our expectation that a majority of our loan acquisitions will continue to require an appraisal to establish market value;

• Our plan to implement representation and warranty relief with respect to borrower asset and employment data and appraised property value, as well as property inspection waivers, in December 2016;

• Our expectation that recent and future planned enhancements to Desktop Underwriter will help our lender customers originate mortgages with increased certainty, efficiency and lower costs, and also help increase access to credit for creditworthy borrowers;

• The expectation that nearly 364,000 new multifamily units will be completed this year;

• Our belief that the increase in the supply of new multifamily units will result in an increase in the national multifamily vacancy rate and a slowdown in rent growth next year;

• Our expectation that significant uncertainty regarding the future of our company and the housing finance system will continue;

• Our expectation that the guaranty fees we receive for managing the credit risk on loans underlying Fannie Mae MBS held by third parties will continue to account for an increasing portion of our net interest income;

• Our expectation that our guaranty fee revenues will increase over the next several years, as loans with lower guaranty fees liquidate from our book of business and are replaced with new loans with higher guaranty fees;

• Our expectation that continued decreases in the size of our retained mortgage portfolio will continue to negatively impact our net interest income and net revenues;

• Our expectation that increases in our guaranty fee revenues will partially offset the negative impact of the decline in our retained mortgage portfolio, and our expectation that the extent to which the positive impact of increased guaranty fee revenues will offset the negative impact of the decline in the size of our retained mortgage portfolio will depend on many factors, including: changes to guaranty fee pricing we may make in the future and their impact on our competitive environment and guaranty fee revenues; the size, composition and quality of our guaranty book of business; the life of the loans in our guaranty book of business; the size, composition and quality of our retained mortgage portfolio; economic and housing market conditions, including changes in interest rates; our market share; and legislative and regulatory changes;

• Our expectation that the single-family serious delinquency rate for the overall mortgage market will continue to decline, and our belief that the rate of this decline will be gradual;

• Our expectation that the national single-family serious delinquency rate will remain high compared with pre-housing crisis levels because it will take some time for the remaining delinquent loans originated prior to 2009 to work their way through the foreclosure process;

• Our forecast that total originations in the U.S. single-family mortgage market in 2016 will increase from 2015 levels by approximately 6% from an estimated $1.73 trillion in 2015 to $1.83 trillion in 2016;

71

• Our forecast that the amount of originations in the U.S. single family mortgage market that are refinancings will increase from an estimated $808 billion in 2015 to $820 billion in 2016;

• Our expectation that the rate of home price appreciation in 2016 will be slightly higher than the rate in 2015;

• Our expectation of significant regional variation in the timing and rate of home price growth;

• Our expectation that our credit losses will be lower in 2016 than our 2015 credit losses;

• Our expectation that our loss reserves will decline further;

• Our expectation that we will pay $187 million that we accrued in the first nine months of 2016, plus additional amounts to be accrued based on our new business purchases in the last three months of 2016, to specified HUD and Treasury funds in February 2017;

• Our expectation that the guaranty fees we collect and the expenses we incur under the TCCA will continue to increase in the future;

• Our plan to reduce our retained mortgage portfolio to no more than $305.4 billion as of December 31, 2016, in compliance with both our senior preferred stock purchase agreement with Treasury and FHFA’s request;

• Our expectation that we will continue purchasing loans from MBS trusts as they become four or more consecutive monthly payments delinquent subject to market conditions, economic benefit, servicer capacity and other factors, including the limit on the amount of mortgage assets that we may own pursuant to the senior preferred stock purchase agreement with Treasury and FHFA’s portfolio plan requirements;

• Our belief that our liquidity contingency plan may be difficult or impossible to execute for a company of our size and in our circumstances;

• Our intention to repay our short-term and long-term debt obligations as they become due primarily through proceeds from the issuance of additional debt securities;

• Our expectation that we may also use proceeds from our mortgage assets to pay our debt obligations;

• Our expectation that we will not eliminate our deficit of core capital over statutory minimum capital;

• Our expectation that, as a result of allowing lenders to remit payment equal to our losses on loans after we have disposed of the related REO, our actual cash receipts relating to our outstanding repurchase requests will be significantly lower than the unpaid principal balance of the loans;

• Our belief that we have taken appropriate steps to mitigate the risk associated with providing lenders with relief from repurchasing certain loans for breaches of certain representations and warranties;

• Our expectation that the credit protection provided by the first loss and mezzanine loss tranches in CAS transactions would absorb all of the losses that would be incurred on these loans in a stressed credit environment, such as a severe or prolonged economic downturn;

• Our expectation that the typical insurance layer in a CIRT transaction provides coverage for losses on the pool that are likely to occur only in a stressed economic environment;

• Our plan to continue to offer our traditional CIRT transactions that cover existing single-family loans in our portfolio;

• FHFA’s expectation that single-family credit risk transfers will continue to be an ongoing conservatorship requirement;

• Our expectation that our acquisition of Alt-A mortgage loans will continue to be minimal in future periods and the percentage of the book of business attributable to Alt-A will continue to decrease over time;

• Our expectation that the serious delinquency rates for single-family loans acquired in more recent years will be higher after the loans have aged, but will not approach the levels of the September 30, 2016 serious delinquency rates of loans acquired in 2005 through 2008;

• Our expectation that the ultimate performance of all our loans will be affected by borrower behavior, public policy and macroeconomic trends, including unemployment, the economy and home prices;

• Our expectation that loans we acquire under Refi Plus and HARP will perform better than the loans they replace because they should either reduce the borrowers’ monthly payments or provide more stable terms than the borrowers’ old loans (for example, by refinancing into a mortgage with a fixed interest rate instead of an adjustable rate);

72

• Our expectation that the volume of refinancings under HARP will continue to remain a small percentage of our acquisitions between now and the program’s expiration, due to the small population of borrowers with loans that have high LTV ratios who are willing to refinance and would benefit from refinancing;

• Our expectation that our institutional credit risk exposure to derivatives clearing organizations and certain of their members may continue to increase in the future if cleared derivative contracts comprise a larger percentage of our derivative instruments;

• Our assumption that the guaranty fee income generated from future business activity will largely replace guaranty fee income lost due to mortgage prepayments;

• Our expectation that, as a result of our various loss mitigation and foreclosure prevention efforts, a portion of the loans in the process of formal foreclosure proceedings will not ultimately foreclose;

• Our plan to complete additional nonperforming loan sales in the future;

• Our expectation that our single-family serious delinquency rate will continue to decrease;

• Our expectation that trial modifications under the new principal reduction modification program will continue through the first quarter of 2017, converting to permanent modifications between now and the second quarter of 2017;

• Our expectation that the level of our multifamily foreclosure activity will remain low as the national multifamily sector continues to exhibit stability;

• Our expectation that we will not remediate the material weakness relating to our disclosure controls and procedures while we are under conservatorship;

• Our expectation that Congress will continue to hold hearings and consider legislation on the future status of Fannie Mae and Freddie Mac, including proposals that would result in Fannie Mae’s liquidation or dissolution;

• Our belief that continued federal government support of our business, as well as our status as a GSE, are essential to maintaining our access to debt funding and that changes or perceived changes in federal government support of our business or our status as a GSE could materially and adversely affect our liquidity, financial condition and results of operations; and

• Our expectation that we will recognize the impact of the new impairment guidance issued in June 2016 that is described in “Note 1, Summary of Significant Accounting Policies—New Accounting Guidance” through a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption.

1. Summary of Significant Accounting Policies

Organization

We are a stockholder-owned corporation organized and existing under the Federal National Mortgage Association Charter Act (the “Charter Act” or our “charter”). We are a government-sponsored enterprise (“GSE”) and we are subject to government oversight and regulation. Our regulators include the Federal Housing Finance Agency (“FHFA”), the U.S. Department of Housing and Urban Development (“HUD”), the U.S. Securities and Exchange Commission (“SEC”), and the U.S. Department of the Treasury (“Treasury”). The U.S. government does not guarantee our securities or other obligations.

Conservatorship

On September 7, 2008, the Secretary of the Treasury and the Director of FHFA announced several actions taken by Treasury and FHFA regarding Fannie Mae, which included: (1) placing us in conservatorship, and (2) the execution of a senior preferred stock purchase agreement by our conservator, on our behalf, and Treasury, pursuant to which we issued to Treasury both senior preferred stock and a warrant to purchase common stock.

Under the Federal Housing Enterprises Financial Safety and Soundness Act of 1992, as amended by the Federal Housing Finance Regulatory Reform Act of 2008 (together, the “GSE Act”), the conservator immediately succeeded to (1) all rights, titles, powers and privileges of Fannie Mae, and of any stockholder, officer or director of Fannie Mae with respect to Fannie Mae and its assets, and (2) title to the books, records and assets of any other legal custodian of Fannie Mae. The conservator has since delegated specified authorities to our Board of Directors and has delegated to management the authority to conduct our day-to-day operations. The conservator retains the authority to withdraw its delegations at any time.

The conservatorship has no specified termination date and there continues to be significant uncertainty regarding our future, including how long we will continue to exist in our current form, the extent of our role in the market, how long we will be in conservatorship, what form we will have and what ownership interest, if any, our current common and preferred stockholders will hold in us after the conservatorship is terminated and whether we will continue to exist following conservatorship. Under the GSE Act, FHFA must place us into receivership if the Director of FHFA makes a written determination that our assets are less than our obligations or if we have not been paying our debts, in either case, for a period of 60 days. In addition, the Director of FHFA may place us into receivership at his discretion at any time for other reasons set forth in the GSE Act, including if we are critically undercapitalized or if we are undercapitalized and have no reasonable prospect of becoming adequately capitalized. Should we be placed into receivership, different assumptions would be required to determine the carrying value of our assets, which could lead to substantially different financial results. We are not aware of any plans of FHFA to fundamentally change our business model or capital structure in the near term.

Impact of U.S. Government Support

We continue to rely on support from Treasury to eliminate any net worth deficits we may experience in the future, which would otherwise trigger our being placed into receivership. Based on consideration of all the relevant conditions and events affecting our operations, including our reliance on the U.S. government, we continue to operate as a going concern and in accordance with our delegation of authority from FHFA.

We believe that continued federal government support of our business, as well as our status as a GSE, are essential to maintaining our access to debt funding. Changes or perceived changes in federal government support of our business or our status as a GSE could materially and adversely affect our liquidity, financial condition and results of operations.

Pursuant to the senior preferred stock purchase agreement, Treasury has committed to provide us with funding to help us maintain a positive net worth thereby avoiding the mandatory receivership trigger described above. We have received a total of $116.1 billion from Treasury pursuant to the senior preferred stock purchase agreement as of September 30, 2016. The aggregate liquidation preference of the senior preferred stock, including the initial aggregate liquidation preference of $1.0 billion, was $117.1 billion as of September 30, 2016. As of September 30, 2016, the amount of remaining funding available to us under the senior preferred stock purchase agreement was $117.6 billion.

Based on the terms of the senior preferred stock, we paid Treasury a dividend of $2.9 billion on September 30, 2016 based on our net worth of $4.1 billion as of June 30,2016 less the applicable capital reserve amount of $1.2 billion. We expect to pay Treasury an additional dividend of $3.0 billion by December 31, 2016 based on our net worth of $4.2 billion as of September 30, 2016 less the applicable capital reserve amount of $1.2 billion. The capital reserve amount was $1.8 billion for

78

FANNIE MAE

(In conservatorship)

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(UNAUDITED)

dividend periods in 2015. The capital reserve amount will continue to be reduced by $600 million each year until it reaches zero on January 1, 2018.

Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the SEC’s instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and note disclosures required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments of a normal recurring nature considered necessary for a fair presentation have been included. The accompanying condensed consolidated financial statements include our accounts as well as the accounts of other entities in which we have a controlling financial interest. All intercompany accounts and transactions have been eliminated. To conform to our current period presentation, we have reclassified certain amounts reported in our prior periods’ condensed consolidated financial statements. Results for the nine months ended September 30, 2016 may not necessarily be indicative of the results for the year ending December 31, 2016. The unaudited interim condensed consolidated financial statements as of and for the nine months ended September 30, 2016 should be read in conjunction with our audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2015 (“2015 Form 10-K”), filed with the SEC on February 19, 2016.

Regulatory Capital

FHFA stated that, during conservatorship, our existing statutory and FHFA-directed regulatory capital requirements will not be binding and FHFA will not issue quarterly capital classifications. We submit capital reports to FHFA and FHFA monitors our capital levels. The deficit of core capital over statutory minimum capital was $138.9 billion as of September 30, 2016 and $139.7 billion as of December 31, 2015.

Under the terms of the senior preferred stock, we are required to pay Treasury a dividend each quarter, when, as and if declared, equal to the excess of our net worth as of the end of the preceding quarter over an applicable capital reserve amount. The Director of FHFA has directed us to make dividend payments on the senior preferred stock on a quarterly basis. Therefore, we do not expect to eliminate our deficit of core capital over statutory minimum capital.

Related Parties

As a result of our issuance to Treasury of the warrant to purchase shares of Fannie Mae common stock equal to 79.9% of the total number of shares of Fannie Mae common stock, we and Treasury are deemed related parties. As of September 30, 2016, Treasury held an investment in our senior preferred stock with an aggregate liquidation preference of $117.1 billion. FHFA’s control of both us and Freddie Mac has caused us, FHFA and Freddie Mac to be deemed related parties. In 2013, Fannie Mae and Freddie Mac established Common Securitization Solutions, LLC (“CSS”), a jointly owned limited liability company to operate a common securitization platform; therefore, CSS is deemed a related party.

Transactions with Treasury

Our administrative expenses were reduced by $14 million and $18 million for the three months ended September 30, 2016 and 2015, respectively, and $45 million and $50 million for the nine months ended September 30, 2016 and 2015, respectively, due to reimbursements from Treasury and Freddie Mac for expenses incurred as program administrator for Treasury’s Home Affordable Modification Program (“HAMP”) and other initiatives under Treasury’s Making Home Affordable Program.

During the three and nine months ended September 30, 2016, we made tax payments of $531 million and $1.1 billion, respectively, to the Internal Revenue Service (“IRS”), a bureau of Treasury. We made tax payments of $100 million and $470 million during the three and nine months ended September 30, 2015. We received no refund from the IRS during the nine months ended September 30, 2016. We received a refund of $277 million from the IRS during the nine months ended September 30, 2015 for income tax adjustments related to tax years 2004 through 2010.

In 2009, we entered into a memorandum of understanding with Treasury, FHFA and Freddie Mac pursuant to which we agreed to provide assistance to state and local housing finance agencies (“HFAs”) through different programs, including a new issue bond (“NIB”) program. As of September 30, 2016, under the NIB program, Fannie Mae and Freddie Mac had $6.5 billion outstanding of pass-through securities backed by single-family and multifamily housing bonds issued by HFAs, which

79

FANNIE MAE

(In conservatorship)

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(UNAUDITED)

is less than 35% of the total original principal under the program, the amount of losses that Treasury would bear. Accordingly, we do not have a potential risk of loss under the NIB program.

The fee revenue and expense related to the Temporary Payroll Tax Cut Continuation Act of 2011 (“TCCA”) are recorded in “Mortgage loans interest income” and “TCCA fees,” respectively, in our condensed consolidated statements of operations and comprehensive income. We recognized $465 million and $413 million in TCCA fees during the three months ended September 30, 2016 and 2015, respectively, and $1.4 billion and $1.2 billion for the nine months ended September 30, 2016 and 2015, respectively, of which $465 million had not been remitted to Treasury as of September 30, 2016.

We incurred expenses in connection with certain funding obligations under the GSE Act, a portion of which is attributable to Treasury’s Capital Magnet and HOPE Funds. These expenses, recognized in “Other expenses, net” in our condensed consolidated statements of operations and comprehensive income, were measured as the product of 4.2 basis points and the unpaid principal balance of our total new business purchases for the respective period. We recognized $40 million and $56 million in other expenses in connection with Treasury’s Capital Magnet and HOPE Funds for the three months ended September 30, 2016 and 2015, respectively, and $96 million and $168 million for the nine months ended September 30, 2016 and 2015, respectively, of which $96 million resulting from 2016 purchases had not been remitted as of September 30, 2016.

In addition to the transactions with Treasury mentioned above, we also purchase and sell Treasury securities in the normal course of business. As of September 30, 2016 and December 31, 2015, we held Treasury securities with a fair value of $31.3 billion and $29.5 billion, respectively, and accrued interest receivable of $28 million and $15 million, respectively. We recognized interest income on these securities held by us of $40 million and $8 million for the three months ended September 30, 2016 and 2015, respectively, and $105 million and $17 million for the nine months ended September 30, 2016 and 2015, respectively.

Transactions with Freddie Mac

As of September 30, 2016 and December 31, 2015, we held Freddie Mac mortgage-related securities with a fair value of $1.4 billion and $5.6 billion, respectively, and accrued interest receivable of $5 million and $22 million, respectively. We recognized interest income on these securities held by us of $19 million and $55 million for the three months ended September 30, 2016 and 2015, respectively, and $100 million and $174 million for the nine months ended September 30, 2016 and 2015, respectively. In addition, Freddie Mac may be an investor in variable interest entities (“VIEs”) that we have consolidated, and we may be an investor in VIEs that Freddie Mac has consolidated.

Transactions with FHFA

The GSE Act authorizes FHFA to establish an annual assessment for regulated entities, including Fannie Mae, which is payable on a semi-annual basis (April and October), for FHFA’s costs and expenses, as well as to maintain FHFA’s working capital. We recognized FHFA assessment fees, which are recorded in “Administrative expenses” in our condensed consolidated statements of operations and comprehensive income, of $28 million for the three months ended September 30, 2016 and 2015, and $84 million for the nine months ended September 30, 2016 and 2015.

Transactions with CSS

In connection with our jointly owned company with Freddie Mac, we contributed $23 million and $17 million for the three months ended September 30, 2016 and 2015, respectively, and $88 million and $47 million for the nine months ended September 30, 2016 and 2015, respectively, of capital into CSS. No other transactions outside of normal business activities have occurred between us and CSS during the nine months ended September 30, 2016 and 2015.

Use of Estimates

Preparing condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect our reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities as of the dates of our condensed consolidated financial statements, as well as our reported amounts of revenues and expenses during the reporting periods. Management has made significant estimates in a variety of areas including, but not limited to, valuation of certain financial instruments and other assets and liabilities and allowance for loan losses. Actual results could be different from these estimates.

On January 1, 2015, we adopted regulatory guidance issued by FHFA which prescribes, among other things, guidance on when a loan should be charged off. This change in estimate resulted in the recognition on January 1, 2015 of (1) $1.8 billion in charge-offs of held for investment loans, (2) $724 million in charge-offs of preforeclosure property taxes and insurance

80

FANNIE MAE

(In conservatorship)

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(UNAUDITED)

receivable and (3) a reduction to our allowance for loan losses and our allowance for preforeclosure property taxes and insurance receivable in amounts equal to charge-offs recognized in connection with held for investment loans and preforeclosure property taxes and insurance receivable.

For the majority of our delinquent single-family loans, we charge off the loan at the date of foreclosure or other liquidation event (such as a deed-in-lieu of foreclosure or a short sale). For a subset of delinquent single-family loans, we charge off the portion of the loans that is deemed uncollectible prior to foreclosure when the loans have been delinquent for a specified length of time and meet specified mark-to-market loan-to-value (“LTV”) ratios. We continue to enhance our data collection and analysis efforts to further refine our loss estimates as we obtain incremental information on the performance of our loans.

Debt

We issue debt in the form of credit risk transfer notes under the Connecticut Avenue Securities (“CAS”) program where repayment of the debt is linked to a reference portfolio of mortgage loans. We account for CAS debt issued in 2016 at amortized cost. As credit events occur and the principal balance of the CAS debt is legally reduced, we recognize an extinguishment gain. We elected the fair value option on CAS debt that was issued prior to 2016.

New Accounting Guidance

Effective January 1, 2016, we adopted guidance regarding consolidation of legal entities such as limited partnerships, limited liability corporations and securitization structures. The impact of the adoption was not material to our condensed consolidated financial statements.

In February 2016, the Financial Accounting Standards Board (“FASB”) issued guidance on leases. The guidance clarified the definition of a lease and requires lessees to recognize on the balance sheet a right-of-use asset, representing its right to use the underlying asset for the lease term, and a corresponding lease liability for all leases with terms greater than 12 months. This guidance supersedes the existing lease guidance; however, we must continue to classify leases to determine how to recognize lease-related expense in our condensed consolidated statements of operations and comprehensive income. The new guidance is effective for us on January 1, 2019. We have evaluated this guidance and determined it will not have a material impact on our condensed consolidated financial statements.

In June 2016, FASB issued guidance that changes the impairment model for most financial assets and certain other instruments. For loans, held-to-maturity debt securities and other financial assets recorded at amortized cost, entities will be required to use a new forward-looking “expected loss” model that will replace today’s “incurred loss” model and generally will result in the earlier recognition of allowances for losses. The guidance is effective on January 1, 2020 with early adoption permitted on January 1, 2019. We will recognize the impact of the new guidance through a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements and the timing of our adoption.

In August 2016, FASB issued guidance regarding classification of certain items within the statement of cash flows in order to reduce diversity in practice with respect to cash flow classifications. The guidance is effective for us on January 1, 2018 and will be applied retrospectively for each period presented. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements.

2. Consolidations and Transfers of Financial Assets

We have interests in various entities that are considered to be VIEs. The primary types of entities are securitization trusts guaranteed by us via lender swap and portfolio securitization transactions and mortgage-backed trusts that were not created by us, as well as housing partnerships that are established to finance the acquisition, construction, development or rehabilitation of affordable multifamily and single-family housing. These interests include investments in securities issued by VIEs, such as Fannie Mae MBS created pursuant to our securitization transactions and our guaranty to the entity. We consolidate the substantial majority of our single-class securitization trusts because our role as guarantor and master servicer provides us with the power to direct matters (primarily the servicing of mortgage loans) that impact the credit risk to which we are exposed. In contrast, we do not consolidate single-class securitization trusts when other organizations have the power to direct these activities.

We continually assess whether we are the primary beneficiary of the VIEs with which we are involved and therefore may consolidate or deconsolidate a VIE through the duration of our involvement. Examples of certain events that may change whether or not we consolidate the VIE include a change in the design of the entity or a change in our ownership in the entity such that we no longer hold substantially all of the certificates issued by a multi-class securitization trust. As of

81

FANNIE MAE

(In conservatorship)

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(UNAUDITED)

September 30, 2016, we consolidated certain VIEs that were not consolidated as of December 31, 2015. As a result of consolidating these entities, which had combined total assets of $154 million in unpaid principal balance as of September 30, 2016, we derecognized our investment in these entities and recognized the assets and liabilities of the consolidated entities at fair value. As of September 30, 2016, we also deconsolidated certain VIEs that were consolidated as of December 31, 2015. As a result of deconsolidating these entities, which had combined total assets of $5.3 billion in unpaid principal balance as of December 31, 2015, we derecognized the assets and liabilities of the entities and recognized at fair value our retained interests as securities in our condensed consolidated balance sheets.

Unconsolidated VIEs

We do not consolidate VIEs when we are not deemed to be the primary beneficiary. Our unconsolidated VIEs include securitization trusts and limited partnerships. The following table displays the carrying amount and classification of our assets and liabilities that relate to our involvement with unconsolidated mortgage-backed trusts.

	As of
	September 30, 2016				December 31, 2015
	(Dollars in millions)
Assets and liabilities recorded in our condensed consolidated balance sheets related to mortgage-backed trusts:
Assets:
Trading securities:
Fannie Mae		$	4,793			$	4,704
Non-Fannie Mae		4,336				5,596
Total trading securities		9,129				10,300
Available-for-sale securities:
Fannie Mae		2,601				3,936
Non-Fannie Mae		6,106				14,644
Total available-for-sale securities		8,707				18,580
Other assets		67				100
Other liabilities		(450		)		(827		)
Net carrying amount		$	17,453			$	28,153

Our maximum exposure to loss generally represents the greater of our recorded investment in the entity or the unpaid principal balance of the assets covered by our guaranty. However, our securities issued by Fannie Mae multi-class resecuritization trusts that are not consolidated do not give rise to any additional exposure to loss as we already consolidate the underlying collateral. The maximum exposure to loss related to unconsolidated mortgage-backed trusts was approximately $24 billion and $34 billion as of September 30, 2016 and December 31, 2015, respectively. The total assets of our unconsolidated mortgage-backed trusts were approximately $170 billion and $220 billion as of September 30, 2016 and December 31, 2015, respectively.

The maximum exposure to loss for our unconsolidated limited partnerships and similar legal entities, which consist of low-income housing tax credit investments, community investments and other entities, was $123 million and the related carrying value was $92 million as of September 30, 2016. As of December 31, 2015, the maximum exposure to loss was $12 million and the related carrying value was a deficit of $24 million. The total assets of these limited partnership investments were $4.0 billion and $4.9 billion as of September 30, 2016 and December 31, 2015, respectively.

The unpaid principal balance of our multifamily loan portfolio was $221.9 billion as of September 30, 2016. As our lending relationship does not provide us with a controlling financial interest in the borrower entity, we do not consolidate these borrowers regardless of their status as either a VIE or a voting interest entity. We have excluded these entities from our VIE disclosures. However, the disclosures we have provided in “Note 3, Mortgage Loans,” “Note 4, Allowance for Loan Losses” and “Note 6, Financial Guarantees” with respect to this population are consistent with the FASB’s stated objectives for the disclosures related to unconsolidated VIEs.

Transfers of Financial Assets

We issue Fannie Mae MBS through portfolio securitization transactions by transferring pools of mortgage loans or mortgage-related securities to one or more trusts or special purpose entities. We are considered to be the transferor when we transfer assets from our own retained mortgage portfolio in a portfolio securitization transaction. For the three months ended September 30, 2016 and 2015, the unpaid principal balance of portfolio securitizations was $76.1 billion and $55.4 billion, respectively. For the nine months ended September 30, 2016 and 2015, the unpaid principal balance of portfolio securitizations was $188.7 billion and $166.3 billion, respectively.

We retain interests from the transfer and sale of mortgage-related securities to unconsolidated single-class and multi-class portfolio securitization trusts. As of September 30, 2016, the unpaid principal balance of retained interests was $4.5 billion and its related fair value was $6.0 billion. The unpaid principal balance of retained interests was $5.5 billion and its related fair value was $6.8 billion as of December 31, 2015. For the three months ended September 30, 2016 and 2015, the principal and interest received on retained interests was $284 million and $273 million, respectively. For the nine months ended September 30, 2016 and 2015, the principal and interest received on retained interests was $907 million and $919 million, respectively.

Managed Loans

Managed loans are on-balance sheet mortgage loans, as well as mortgage loans that we have securitized in unconsolidated portfolio securitization trusts. The unpaid principal balance of securitized loans in unconsolidated portfolio securitization trusts, which are primarily loans that are guaranteed or insured, in whole or in part, by the U.S. government, was $1.4 billion and $1.6 billion as of September 30, 2016 and December 31, 2015, respectively. For information on our on-balance sheet mortgage loans, see “Note 3, Mortgage Loans.”

3.  Mortgage Loans

We own single-family mortgage loans, which are secured by four or fewer residential dwelling units, and multifamily mortgage loans, which are secured by five or more residential dwelling units. We classify these loans as either held for investment (“HFI”) or held for sale (“HFS”). We report the carrying value of HFI loans at the unpaid principal balance, net of unamortized premiums and discounts, other cost basis adjustments, and an allowance for loan losses. We report the carrying value of HFS loans at the lower of cost or fair value and record valuation changes in “Investment gains, net” in our condensed consolidated statements of operations and comprehensive income. We define the recorded investment of HFI loans as unpaid principal balance, net of unamortized premiums and discounts, other cost basis adjustments, and accrued interest receivable.

For purposes of the single-family mortgage loan disclosures below, we define “primary” class as mortgage loans that are not included in other loan classes; “government” class as mortgage loans guaranteed or insured, in whole or in part, by the U.S. government or one of its agencies, that are not Alt-A; and “other” class as loans with higher-risk characteristics, such as interest-only loans and negative-amortizing loans, that are neither government nor Alt-A.

During the three and nine months ended September 30, 2016, we redesignated loans with a carrying value of $652 million and $2.3 billion, respectively, from HFI to HFS. During the three and nine months ended September 30, 2015, we redesignated loans with a carrying value of $1.3 billion and $5.9 billion, respectively, from HFI to HFS. We sold loans with an unpaid principal balance of $1.6 billion and $4.2 billion during the three and nine months ended September 30, 2016, respectively. We sold loans with an unpaid principal balance of $1.9 billion and $2.5 billion during the three and nine months ended September 30, 2015, respectively.

The recorded investment of single-family mortgage loans for which formal foreclosure proceedings are in process was $19.5 billion and $25.6 billion as of September 30, 2016 and December 31, 2015, respectively. As a result of our various loss mitigation and foreclosure prevention efforts, we expect that a portion of the loans in the process of formal foreclosure proceedings will not ultimately foreclose.

Nonaccrual Loans

We discontinue accruing interest on loans when we believe collectibility of principal or interest is not reasonably assured, which for a single-family loan we have determined, based on our historical experience, to be when the loan becomes two months or more past due according to its contractual terms. Interest previously accrued but not collected is reversed through interest income at the date a loan is placed on nonaccrual status. We return a non-modified single-family loan to accrual status at the point that the borrower brings the loan current. We return a modified single-family loan to accrual status at the point that the borrower successfully makes all required payments during the trial period (generally three to four months) and the modification is made permanent. We place a multifamily loan on nonaccrual status when the loan becomes three months or more past due according to its contractual terms or is deemed to be individually impaired, unless the loan is well secured such that collectibility of principal and accrued interest is reasonably assured. We return a multifamily loan to accrual status when the borrower cures the delinquency of the loan or we otherwise determine that the loan is well secured such that collectibility is reasonably assured.

Troubled Debt Restructurings

A modification to the contractual terms of a loan that results in granting a concession to a borrower experiencing financial difficulties is considered a TDR. In addition to formal loan modifications, we also engage in other loss mitigation activities with troubled borrowers, which include repayment plans and forbearance arrangements, both of which represent informal agreements with the borrower that do not result in the legal modification of the loan’s contractual terms. We account for these informal restructurings as a TDR if we defer more than three missed payments. We also classify loans to certain borrowers who have received bankruptcy relief as TDRs.

The substantial majority of the loan modifications we complete result in term extensions, interest rate reductions or a combination of both. During the three months ended September 30, 2016 and 2015, the average term extension of a single-family modified loan was 153 months and 159 months, respectively, and the average interest rate reduction was 0.82 and 0.69

4. Allowance for Loan Losses

We maintain an allowance for loan losses for HFI loans held by Fannie Mae and loans backing Fannie Mae MBS issued from consolidated trusts. When calculating our allowance for loan losses, we consider our net recorded investment in the loan at the balance sheet date, which includes unpaid principal balance, net of amortized premiums and discounts, and other cost basis adjustments. We record charge-offs as a reduction to the allowance for loan losses when losses are confirmed through the receipt of assets in full satisfaction of a loan, such as the underlying collateral upon foreclosure or cash upon completion of a short sale. Additionally, we record charge-offs as a reduction to our allowance for loan losses when a loan is determined to be uncollectible or upon the redesignation of nonperforming loans from HFI to HFS.

We aggregate single-family HFI loans that are not individually impaired based on similar risk characteristics for purposes of estimating incurred credit losses and establishing a collective single-family loss reserve using an econometric model that derives an overall loss reserve estimate. We base our allowance methodology on historical events and trends, such as loss severity (in event of default), default rates, and recoveries from mortgage insurance contracts and other credit enhancements. In addition, management performs a review of the observable data used in its estimate to ensure it is representative of prevailing economic conditions and other events existing as of the balance sheet date.

Individually impaired single-family loans currently include those restructured in a TDR and acquired credit-impaired loans. When a loan has been restructured, we measure impairment using a cash flow analysis discounted at the loan’s original effective interest rate. However, if we expect to recover our recorded investment in an individually impaired loan through probable foreclosure of the underlying collateral, we measure impairment based on the fair value of the collateral, reduced by estimated disposal costs and adjusted for estimated proceeds from mortgage, flood, or hazard insurance and other credit enhancements.

We identify multifamily loans for evaluation for impairment through a credit risk assessment process. If we determine that a multifamily loan is individually impaired, we generally measure impairment on that loan based on the fair value of the

underlying collateral less estimated costs to sell the property. We establish a collective loss reserve for all loans in our multifamily guaranty book of business that are not individually impaired using an internal model that applies loss factors to loans in similar risk categories. Our loss factors are developed based on our historical default and loss severity experience.

6.  Financial Guarantees

We recognize a guaranty obligation for our obligation to stand ready to perform on our guarantees to unconsolidated trusts and other guaranty arrangements. These guarantees expose us to credit losses on the mortgage loans or, in the case of mortgage-related securities, the underlying mortgage loans of the related securities. The remaining contractual terms of our guarantees range from 1 day to 36 years; however, the actual term of each guaranty may be significantly less than the contractual term based on the prepayment characteristics of the related mortgage loans.

The following table displays our maximum exposure, guaranty obligation recognized in our condensed consolidated balance sheets and the maximum potential recovery from third parties through available credit enhancements and recourse related to our financial guarantees.

⁽²⁾  Recoverability of such credit enhancements and recourse is subject to, among other factors, our mortgage insurers’ and financial guarantors’ ability to meet their obligations to us. For information on our mortgage insurers, see “Note 13, Concentrations of Credit Risk.”

⁽³⁾  Primarily consists of credit enhancements and long-term standby commitments.

The fair value of our guaranty obligations associated with the Fannie Mae MBS included in “Investments in securities” in our condensed consolidated balance sheets was $433 million and $488 million as of September 30, 2016 and December 31, 2015, respectively. These Fannie Mae MBS consist primarily of private-label wraps where our guaranty arrangement is with an unconsolidated MBS trust.

Intraday Line of Credit

We use a secured intraday funding line of credit provided by a large financial institution. We post collateral which, in some circumstances, the secured party has the right to repledge to third parties. As this line of credit is an uncommitted intraday loan facility, we may be unable to draw on it if and when needed. The line of credit under this facility was $15.0 billion as of September 30, 2016 and December 31, 2015. We had no borrowings outstanding under this line of credit as of September 30, 2016.

9.  Derivative Instruments

Derivative instruments are an integral part of our strategy in managing interest rate risk. Derivative instruments may be privately-negotiated, bilateral contracts, or they may be listed and traded on an exchange. We refer to our derivative transactions made pursuant to bilateral contracts as our over-the-counter (“OTC”) derivative transactions and our derivative transactions accepted for clearing by a derivatives clearing organization as our cleared derivative transactions. We typically do not settle the notional amount of our risk management derivatives; rather, notional amounts provide the basis for calculating actual payments or settlement amounts. The derivatives we use for interest rate risk management purposes consist primarily of interest rate swaps and interest rate options.

We enter into various forms of credit risk sharing agreements, including credit risk transfer transactions, swap credit enhancements and mortgage insurance contracts, that we account for as derivatives. The majority of our credit-related derivatives are credit risk transfer transactions, whereby a portion of the credit risk associated with losses on a reference pool of mortgage loans is transferred to a third party.

We enter into forward purchase and sale commitments that lock in the future delivery of mortgage loans and mortgage-related securities at a fixed price or yield. Certain commitments to purchase mortgage loans and purchase or sell mortgage-related securities meet the criteria of a derivative. We typically settle the notional amount of our mortgage commitments that are accounted for as derivatives.

We recognize all derivatives as either assets or liabilities in our condensed consolidated balance sheets at their fair value on a trade date basis. Fair value amounts, which are netted to the extent a legal right of offset exists and is enforceable by law at the counterparty level and are inclusive of the right or obligation associated with the cash collateral posted or received, are recorded in “Other assets” or “Other liabilities” in our condensed consolidated balance sheets. See “Note 15, Fair Value” for additional information on derivatives recorded at fair value. We present cash flows from derivatives as operating activities in our condensed consolidated statements of cash flows.

The following table displays the notional amount and estimated fair value of our asset and liability derivative instruments.

⁽²⁾  The netting adjustment represents the effect of the legal right to offset under legally enforceable master netting arrangements to settle with the same counterparty on a net basis, including cash collateral posted and received. Cash collateral posted was $6.7 billion and $4.9 billion as of September 30, 2016 and December 31, 2015, respectively. Cash collateral received was $419 million and $314 million as of September 30, 2016 and December 31, 2015, respectively.

A majority of our OTC derivative contracts contain provisions that require our senior unsecured debt to maintain a minimum credit rating from S&P and Moody’s. If our senior unsecured debt credit ratings were downgraded to established thresholds in these derivative contracts, which range from A+ to BBB+, we could be required to provide additional collateral to or terminate transactions with certain counterparties. The aggregate fair value of all OTC derivatives with credit-risk-related contingent features that were in a net liability position was $3.3 billion and $2.4 billion as of September 30, 2016 and December 31, 2015, respectively, for which we posted collateral of $3.3 billion and $2.2 billion in the normal course of business as of September 30, 2016 and December 31, 2015, respectively. Had all of the credit-risk-related contingency features underlying these agreements been triggered, an additional $85 million and $257 million would have been required to be posted as collateral or to immediately settle our positions based on the individual agreements and our fair value position as of September 30, 2016 and December 31, 2015, respectively. A reduction in our credit ratings may also cause derivatives clearing organizations or their members to demand that we post additional collateral for our cleared derivatives contracts.

We record all derivative gains and losses, including accrued interest, in “Fair value losses, net” in our condensed consolidated statements of operations and comprehensive income. The following table displays, by type of derivative instrument, the fair value gains and losses, net on our derivatives.

Derivative Counterparty Credit Exposure

Our derivative counterparty credit exposure relates principally to interest rate derivative contracts. We are exposed to the risk that a counterparty in a derivative transaction will default on payments due to us, which may require us to seek a replacement derivative from a different counterparty. This replacement may be at a higher cost, or we may be unable to find a suitable replacement. We manage our derivative counterparty credit exposure relating to our risk management derivative transactions mainly through enforceable master netting arrangements, which allow us to net derivative assets and liabilities with the same counterparty or clearing organization and clearing member. For our OTC derivative transactions, we require counterparties to post collateral, which may include cash, U.S. Treasury securities, agency debt and agency mortgage-related securities.

See “Note 14, Netting Arrangements” for information on our rights to offset assets and liabilities.

10. Earnings (Loss) Per Share

The calculation of income available to common stockholders and earnings per share is based on the underlying premise that all income after payment of dividends on preferred shares is available to and will be distributed to common stockholders. However, as a result of our conservatorship status and the terms of the senior preferred stock, no amounts are available to distribute as dividends to common or preferred stockholders (other than to Treasury as holder of the senior preferred stock).

The following table displays the computation of basic and diluted earnings (loss) per share of common stock.

⁽¹⁾  Dividends distributed or available for distribution were calculated based on our net worth as of the end of the fiscal quarters, less the applicable capital reserve amount. See “Note 1, Summary of Significant Accounting Policies” in our 2015 Form 10-K for additional information on our senior preferred stock agreement and our payment of dividends to Treasury.

⁽²⁾  Includes 4.6 billion of weighted average shares of common stock that would be issued upon the full exercise of the warrant issued to Treasury from the date the warrant was issued through September 30, 2016 and 2015.

11. Segment Reporting

Our three reportable segments are: Single-Family, Multifamily and Capital Markets. We use these three segments to generate revenue and manage business risk, and each segment is based on the type of business activities it performs. Under our segment reporting, the sum of the results for our three business segments does not equal our condensed consolidated statements of operations and comprehensive income as we separate the activity related to our consolidated trusts from the results generated by our three segments. Our business segment financial results include directly attributable revenues and expenses. We apply accounting methods for segment reporting purposes that differ from our condensed consolidated results. Additionally, we allocate to each of our segments: (1) capital using FHFA minimum capital requirements adjusted for over- or under-capitalization; (2) indirect administrative costs; and (3) a provision for federal income taxes. In addition, we allocate intracompany guaranty fee income as a charge from the Single-Family and Multifamily segments to Capital Markets for managing the credit risk on mortgage loans held by the Capital Markets group. Therefore, we reconcile the sum of the results for our three business segments to our condensed consolidated results of operations.

13. Concentrations of Credit Risk

Risk Characteristics of our Guaranty Book of Business

We gauge our performance risk under our guaranty based on the delinquency status of the mortgage loans we hold in our retained mortgage portfolio, or in the case of mortgage-backed securities, the mortgage loans underlying the related securities.

For single-family loans, management monitors the serious delinquency rate, which is the percentage of single-family loans 90 days or more past due or in the foreclosure process, and loans that have higher risk characteristics, such as high mark-to-market LTV ratios.

For multifamily loans, management monitors the serious delinquency rate, which is the percentage of loans, based on unpaid principal balance, that are 60 days or more past due, and other loans that have higher risk characteristics, to determine our overall credit quality indicator. Higher risk characteristics include, but are not limited to, current debt service coverage ratio (“DSCR”) below 1.0 and high original LTV ratios. We stratify multifamily loans into different internal risk categories based on the credit risk inherent in each individual loan.

For single-family and multifamily loans, we use this information, in conjunction with housing market and economic conditions, to structure our pricing and our eligibility and underwriting criteria to reflect the current risk of loans with these higher-risk characteristics, and in some cases we decide to significantly reduce our participation in riskier loan product categories. Management also uses this data together with other credit risk measures to identify key trends that guide the development of our loss mitigation strategies.

The following tables display the delinquency status and serious delinquency rates for specified loan categories of our single-family conventional and total multifamily guaranty book of business.

Although we use the most recently available results of our multifamily borrowers, there is a lag in reporting, which typically can range from 3 to 6 months but in some cases may be longer.

Other Concentrations

Mortgage Sellers and Servicers.  Mortgage servicers collect mortgage and escrow payments from borrowers, pay taxes and insurance costs from escrow accounts, monitor and report delinquencies, and perform other required activities on our behalf. Our mortgage sellers and servicers may also be obligated to repurchase loans or foreclosed properties, reimburse us for losses or provide other remedies under certain circumstances, such as if it is determined that the mortgage loan did not meet our underwriting or eligibility requirements, if certain loan representations and warranties are violated or if mortgage insurers rescind coverage. However, under our revised representation and warranty framework, we no longer require repurchase for loans that have breaches of certain selling representations and warranties if they have met specified criteria for relief. Our business with mortgage servicers is concentrated. Our five largest single-family mortgage servicers, including their affiliates, serviced approximately 40% of our single-family guaranty book of business as of September 30, 2016, compared with approximately 44% as of December 31, 2015. Our five largest multifamily mortgage servicers, including their affiliates, serviced approximately 46% of our multifamily guaranty book of business as of September 30, 2016, compared with approximately 45% as of December 31, 2015.

If a significant mortgage seller or servicer counterparty, or a number of mortgage sellers or servicers, fails to meet their obligations to us, it could result in an increase in our credit losses and credit-related expense, and have a material adverse effect on our results of operations, liquidity, financial condition and net worth.

Mortgage Insurers.  Mortgage insurance “risk in force” generally represents our maximum potential loss recovery under the applicable mortgage insurance policies. We had total mortgage insurance coverage risk in force of $124.2 billion and $117.9 billion on the single-family mortgage loans in our guaranty book of business as of September 30, 2016 and December 31, 2015, respectively, which represented 4% of our single-family guaranty book of business as of September 30, 2016 and December 31, 2015. Our primary mortgage insurance coverage risk in force was $123.6 billion and $117.2 billion as of September 30, 2016 and December 31, 2015, respectively. Our pool mortgage insurance coverage risk in force was $646 million and $736 million as of September 30, 2016 and December 31, 2015, respectively. Our top four mortgage insurance companies provided 77% and 79% of our mortgage insurance coverage risk in force as of September 30, 2016 and December 31, 2015, respectively.

Of our largest primary mortgage insurers, PMI Mortgage Insurance Co., Triad Guaranty Insurance Corporation and Republic Mortgage Insurance Company are under various forms of supervised control by their state regulators and are in run-off. Entering run-off may close off a source of profits and liquidity that may have otherwise assisted a mortgage insurer in paying claims under insurance policies, and could also cause the quality and speed of its claims processing to deteriorate. These three mortgage insurers provided a combined $8.5 billion, or 7%, of our risk in force mortgage insurance coverage of our single-family guaranty book of business as of September 30, 2016.

Although the financial condition of our mortgage insurer counterparties currently approved to write new business has improved in recent years, there is still risk that these counterparties may fail to fulfill their obligations to pay our claims under insurance policies. If we determine that it is probable that we will not collect all of our claims from one or more of our mortgage insurer counterparties, it could result in an increase in our loss reserves, which could adversely affect our results of operations, liquidity, financial condition and net worth.

When we estimate the credit losses that are inherent in our mortgage loans and under the terms of our guaranty obligations we also consider the recoveries that we will receive on primary mortgage insurance, as mortgage insurance recoveries would reduce the severity of the loss associated with defaulted loans. We evaluate the financial condition of our mortgage insurer counterparties and adjust the contractually due recovery amounts to ensure that only probable losses as of the balance sheet date are included in our loss reserve estimate. As a result, if our assessment of one or more of our mortgage insurer counterparties’ ability to fulfill their respective obligations to us worsens, it could result in an increase in our loss reserves. As

(UNAUDITED)

of September 30, 2016 and December 31, 2015, the amount by which our estimated benefit from mortgage insurance reduced our total loss reserves was $1.5 billion and $2.3 billion, respectively.

We had outstanding receivables of $1.0 billion recorded in “Other assets” in our condensed consolidated balance sheets as of September 30, 2016 and $1.2 billion as of December 31, 2015 related to amounts claimed on insured, defaulted loans excluding government insured loans. Of this amount, $135 million as of September 30, 2016 and $241 million as of December 31, 2015 was due from our mortgage sellers or servicers. We assessed the total outstanding receivables for collectibility, and they are recorded net of a valuation allowance of $658 million as of September 30, 2016 and $770 million as of December 31, 2015. The valuation allowance reduces our claim receivable to the amount which is considered probable of collection as of September 30, 2016 and December 31, 2015.

For information on credit risk associated with our derivative transactions and repurchase agreements refer to “Note 9, Derivative Instruments” and “Note 14, Netting Arrangements.”

14. Netting Arrangements

We use master netting arrangements, which allow us to offset certain financial instruments and collateral with the same counterparty, to minimize counterparty credit exposure. The tables below display information related to derivatives, securities purchased under agreements to resell or similar arrangements, and securities sold under agreements to repurchase or similar arrangements, which are subject to an enforceable master netting arrangement or similar agreement that are either offset or not offset in our condensed consolidated balance sheets.

The fair value of non-cash collateral we pledged was $1.2 billion and $197 million as of September 30, 2016 and December 31, 2015, respectively, which the counterparty was permitted to sell or repledge. The fair value of non-cash collateral received was $40.7 billion and $38.0 billion, of which $37.4 billion and $36.2 billion could be sold or repledged as of September 30, 2016 and December 31, 2015, respectively. None of the underlying collateral was sold or repledged as of September 30, 2016 and December 31, 2015.

Derivative instruments are recorded at fair value and securities purchased under agreements to resell or similar arrangements are recorded at amortized cost in our condensed consolidated balance sheets.

We determine our rights to offset the assets and liabilities presented above with the same counterparty, including collateral posted or received, based on the contractual arrangements entered into with our individual counterparties and various rules and regulations that would govern the insolvency of a derivative counterparty. The following is a description, under various agreements, of the nature of those rights and their effect or potential effect on our financial position.

The terms of the majority of our contracts for OTC risk management derivatives are governed under master agreements of the International Swaps and Derivatives Association Inc. (“ISDA”). These agreements provide that all transactions entered into under the agreement with the counterparty constitute a single contractual relationship. An event of default by the counterparty

FANNIE MAE

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(UNAUDITED)

allows the early termination of all outstanding transactions under the same ISDA agreement and we may offset all outstanding amounts related to the terminated transactions including collateral posted or received.

The terms of our contracts for cleared derivatives are governed under the rules of the clearing organization and the agreement between us and the clearing member of that clearing organization. In the event of a clearing organization default, all open positions at the clearing organization are closed and a net position (on a clearing member by clearing member basis) is calculated. Unless otherwise transferred, in the event of a clearing member default, all open positions cleared through that clearing member are closed and a net position is calculated.

The terms of our contracts for mortgage commitment derivatives are primarily governed by the Fannie Mae Single-Family Selling Guide (“Guide”), for Fannie Mae-approved lenders, or Master Securities Forward Transaction Agreements (“MSFTA”), for counterparties that are not Fannie Mae-approved lenders. In the event of default by the counterparty, both the Guide and the MSFTA allow us to terminate all outstanding transactions under the applicable agreement and offset all outstanding amounts related to the terminated transactions including collateral posted or received. Under the Guide, upon a lender event of default, we generally may offset any amounts owed to a lender against any amounts a lender may owe us under any other existing agreement, regardless of whether or not such other agreements are in default or payments are immediately due.

The terms of our contracts for securities purchased under agreements to resell and securities sold under agreements to repurchase are governed by Master Repurchase Agreements, which are based on the guidelines prescribed by the Securities Industry and Financial Markets Association. Master Repurchase Agreements provide that all transactions under the agreement constitute a single contractual relationship. An event of default by the counterparty allows the early termination of all outstanding transactions under the same agreement and we may offset all outstanding amounts related to the terminated transactions including collateral posted or received.

We also have securities purchased under agreements to resell which we transact through the Fixed Income Clearing Corporation (“FICC”). Under the rules of the FICC, all agreements for securities purchased under agreements to resell that are submitted to the FICC for clearing become transactions with the FICC that are subject to FICC clearing rules. In the event of a FICC default, all open positions at the FICC are closed and a net position is calculated.

15.  Fair Value

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.

⁽¹⁾  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⁾  Default rate as disclosed represents the estimated beginning annualized rate of default and is used as a basis to forecast the future default rates that serve as an input for valuation.

In our condensed consolidated balance sheets certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when we evaluate loans for impairment). We did not have any Level 1 assets or liabilities held as of September 30, 2016 or December 31, 2015 that were measured at fair value on a nonrecurring basis. We held $475 million and $17 million in Level 2 assets, comprised of mortgage loans held for sale, and no Level 2 liabilities that were measured at fair value on a nonrecurring basis as of September 30, 2016 and December 31, 2015, respectively.

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 in more specific situations.

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.

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 in active markets 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.

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.

Dealer Mark: This valuation technique utilizes one dealer 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.

127

FANNIE MAE

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(UNAUDITED)

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.

For 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: We derive the fair value of mortgage loans primarily using a build-up valuation technique. In the build-up valuation technique we start with the base value for our Fannie Mae MBS and then add or subtract the fair value of the associated guaranty asset, guaranty obligation (“GO”) and master servicing arrangement. We use observable market values of Fannie Mae MBS with similar characteristics, either on a pool or loan level, 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. 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 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 also estimate the fair value of the GO using our current guaranty pricing and adjust that pricing, as appropriate, for the seasoning of the collateral when such transactions reflect credit characteristics of loans held in our portfolio. As a result, the fair value of our mortgage loans will change when the pricing for our credit guaranty changes in the GSE securitization market.

Our performing 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 and certain reperforming loans represents an estimate of the prices we would receive if we were to sell these loans in the whole-loan market. Key factors that influence the price of these loans include collateral value, estimated loan cash flows and mortgage insurance. Collateral value is derived from the current estimated mark-to-market LTV ratio of the individual loan and, where appropriate, a state-level distressed property sales discount. Cash flow characteristics include attributes such as the weighted average coupon rate and loan payment history. 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. Fair value is estimated from the extrapolation of indicative sample bids obtained from multiple active market participants plus the estimated value of any applicable mortgage insurance. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

We estimate the fair value for a portion of our senior-subordinated trust structures using the average of two or more vendor prices at the security level as a proxy for estimating loan fair value. 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 our reverse mortgages using the single vendor valuation technique. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

Internal Model: For loans whose value it has been determined should be based on collateral value, we use an internal proprietary distressed home price model. The internal model used in this process takes one of two approaches when valuing the collateral.

The first approach relies on comparable foreclosed property sales to estimate the value of the target collateral. The comparable foreclosed property sales approach uses various factors such as geographic distance, transaction time and the value difference. The second approach referred to as the median Metropolitan Statistical Area (“MSA”) is based on the median of all the foreclosure sales of REOs in a specific MSA. Using this sales price, MSA level discount is computed and applied to the estimated non distressed value to derive an estimated fair value. If there are not enough REO sales in a specific MSA, a median state level foreclosure discount is used to estimate the fair value.

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 median MSA is based on historical accuracy. 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. 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 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 DSCR. 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 next highest priority valuation methodology available, 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 changes in market conditions. 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 third-party valuations (both current and walk forward). Based on the number of properties measured as of September 30, 2016, these methodologies comprised approximately 74% of our valuations, while accepted offers comprised approximately 20% of our valuations. Based on the number of properties measured as of December 31, 2015, these methodologies comprised approximately 77% of our valuations, while accepted offers comprised approximately 18% 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 significant 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.

We review the appraisals and broker price opinions received to determine if they have been performed in accordance with applicable standards and if the results are consistent with our observed transactions on similar properties. We make necessary adjustments as required.

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.

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 Fannie Mae debt instruments and debt of consolidated trusts with embedded derivatives, which are recorded in our condensed consolidated balance sheets at fair value on a recurring basis.

We classify debt instruments that have quoted market prices in active markets for similar liabilities when traded as assets as Level 2 of the valuation hierarchy. For all valuation techniques used for debts instruments where there is limited activity or less transparency around these inputs to the valuation, these debt instruments are classified as Level 3 of the valuation hierarchy.

A description of our debt valuation techniques is as follows:

Consensus: We estimate the fair value of debt of Fannie Mae and our debt of consolidated trusts using an average of two or more vendor prices or dealer marks that represents estimated fair value for similar liabilities when traded as assets. 

Single Vendor: We estimate the fair value of debt of Fannie Mae and our debt of consolidated trusts using a single vendor price that represents estimated fair value for these liabilities when traded as assets.

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 the debt of Fannie Mae and our debt of consolidated trusts using a discounted cash flow technique that uses spreads based on market assumptions where available.

The valuation methodology and inputs used in estimating the fair value of MBS assets are described under “Trading Securities and Available-for-Sale Securities.” 

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 and Valuation Group, along with the Credit Valuation team, are responsible for the estimation and verification of the fair value for the majority of our financial assets and financial liabilities. These groups also provide updates to the Finance Committee on relevant market information, pricing trends, significant valuation challenges and the resolution of those challenges. The Pricing and Valuation Group, along with the Credit Valuation team, reside within our Finance Division and are independent of any trading or market related activities. Fair value measurements for acquired property and collateral dependent loans are determined by other valuation groups in the Finance Division.

Our Finance Committee includes senior representation from our Capital Markets segment, our Enterprise Risk Management and our Finance Division, and is responsible for reviewing and approving the methods used in valuing financial instruments for the purpose of financial reporting. The composition of the Finance Committee is set forth in its charter, which was approved by the Chief Executive Officer. Based on its review of valuation methodologies and fair value results for various financial instruments used for financial reporting, the Finance Committee has the ultimate responsibility over all valuation processes and results.

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 and Valuation Group performs various review and validation procedures prior to utilizing these prices in our fair value estimation process. We validate 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 vendors 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 levels of liquidity in the marketplace. If we determine that a price provided to us is outside established parameters or in certain other circumstances, 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 Real Estate Property Valuation Group utilizes third-party appraisals and broker price opinions along with internal models and market data to compare the values received on a property and determine the valuation risk based on several factors including the deviation between the various values. The property valuation team reviews the valuations with higher valuation risk for reasonableness. The internal models utilized in the process are subject to oversight from the Model Risk Management Group, which is responsible for establishing risk management controls and for reviewing models used in the determination of fair value measurements for financial reporting. In addition, our Quality Control Group reviews the 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.

For fair value reporting purposes, we mark each property in inventory each month, incorporating the values assigned by the property valuation team along with other information including accepted offers and predictions from our proprietary distressed home price model.

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 Finance Committee.

Our Real Estate Property Valuation Group reviews appraisals and broker price opinions to determine the most appropriate value by comparing data within these products with current comparable properties and market data. We conduct regular performance reviews of the counterparties that provide products and services for this process. In addition, valuation results and trend analyses are reviewed regularly by management responsible for valuing and disposing of real estate.

Fair Value of Financial Instruments

The following table displays the carrying value and estimated fair value of our financial instruments. The fair value of financial instruments we disclose includes commitments to purchase multifamily and single-family mortgage loans 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 all non-financial instruments; therefore, 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.

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 collateral that is easily traded. If we were 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.” These loans are classified

134

FANNIE MAE

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(UNAUDITED)

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.

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 similar 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.

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. If we were 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 inputs.

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 as Level 3. 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 also classified as Level 3.

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. Therefore, we take a further discount of the present value for these liquidity considerations. This discount is based on market quotes from third-party pricing services.

The fair value of the guaranty assets includes the fair value of any associated buy-ups.

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 as Level 3. The valuation methodology and inputs used in estimating the fair value of the guaranty obligations are described under “Fair Value Measurement—Mortgage Loans Held for Investment—Build-up.”

Fair Value Option

We elected the fair value option for our credit risk sharing debt securities issued under our CAS series issued prior to January 1, 2016 and certain loans that 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 such instruments.

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 “Interest income—Mortgage loans” and interest expense for the debt instruments is recorded in “Interest expense—Long-term debt” 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.

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 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 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 credit risk.

16.  Commitments and Contingencies

We are party to various types of legal actions and proceedings, including actions brought on behalf of various classes of claimants. We also are subject to regulatory examinations, inquiries and investigations, and other information gathering requests. In some of the matters, indeterminate amounts are sought. Modern pleading practice in the U.S. permits considerable variation in the assertion of monetary damages or other relief. Jurisdictions may permit claimants not to specify the monetary damages sought or may permit claimants to state only that the amount sought is sufficient to invoke the jurisdiction of the trial court. This variability in pleadings, together with our and our counsel’s actual experience in litigating or settling claims, leads us to conclude that the monetary relief that may be sought by plaintiffs bears little relevance to the merits or disposition value of claims.

On a quarterly basis, we review relevant information about all pending legal actions and proceedings for the purpose of evaluating and revising our contingencies, accruals and disclosures.

We have substantial and valid defenses to the claims in the proceedings described below and intend to defend these matters vigorously. However, legal actions and proceedings of all types are subject to many uncertain factors that generally cannot be predicted with assurance. Accordingly, the outcome of any given matter and the amount or range of potential loss at particular points in time is frequently difficult to ascertain. Uncertainties can include how fact finders will evaluate documentary evidence and the credibility and effectiveness of witness testimony, and how courts will apply the law. Disposition valuations are also subject to the uncertainty of how opposing parties and their counsel may view the evidence and applicable law.

We establish an accrual for matters when a loss is probable and we can reasonably estimate the amount of such loss. For legal actions or proceedings where there is only a reasonable possibility that a loss may be incurred, or where we are not currently able to estimate the reasonably possible loss or range of loss, we do not establish an accrual. We are often unable to estimate the possible losses or ranges of losses, particularly for proceedings that are in their early stages of development, where plaintiffs seek indeterminate or unspecified damages, where there may be novel or unsettled legal questions relevant to the proceedings, or where settlement negotiations have not occurred or progressed.

Given the uncertainties involved in any action or proceeding, regardless of whether we have established an accrual, the ultimate resolution of certain of these matters may be material to our operating results for a particular period, depending on, among other factors, the size of the loss or liability imposed and the level of our net income or loss for that period.

In addition to the matters specifically described below, we are involved in a number of legal and regulatory proceedings that arise in the ordinary course of business that we do not expect will have a material impact on our business or financial condition. We have also advanced fees and expenses of certain current and former officers and directors in connection with various legal proceedings pursuant to our bylaws and indemnification agreements.

Senior Preferred Stock Purchase Agreements Litigation

A number of putative class action lawsuits were filed in the U.S. District Court for the District of Columbia against us, FHFA as our conservator, Treasury and Freddie Mac from July through September 2013 by shareholders of Fannie Mae and/or Freddie Mac challenging the August 2012 amendment to each company’s senior preferred stock purchase agreement with Treasury. These lawsuits were consolidated and, on December 3, 2013, plaintiffs (preferred and common shareholders of Fannie Mae and/or Freddie Mac) filed a consolidated class action complaint in the U.S. District Court for the District of Columbia against us, FHFA as our conservator, Treasury and Freddie Mac (“In re Fannie Mae/Freddie Mac Senior Preferred Stock Purchase Agreement Class Action Litigations”). The preferred shareholder plaintiffs allege that the net worth sweep dividend provisions of the senior preferred stock that were implemented pursuant to the August 2012 amendments to the senior preferred stock purchase agreements nullified certain of the shareholders’ rights, particularly the right to receive dividends. The common shareholder plaintiffs allege that the August 2012 amendments constituted a taking of their property

137

FANNIE MAE

(UNAUDITED)

by requiring that all future profits of Fannie Mae and Freddie Mac be paid to Treasury. Plaintiffs allege claims for breach of contract and breach of the implied covenant of good faith and fair dealing against us, FHFA and Freddie Mac, a takings claim against FHFA and Treasury, and a breach of fiduciary duty claim derivatively on our and Freddie Mac’s behalf against FHFA and Treasury. Plaintiffs seek to represent several classes of preferred and/or common shareholders of Fannie Mae and/or Freddie Mac who held stock as of the public announcement of the August 2012 amendments. Plaintiffs seek unspecified damages, equitable and injunctive relief, and costs and expenses, including attorneys’ fees.

A non-class action suit, Arrowood Indemnity Company v. Fannie Mae, was filed in the U.S. District Court for the District of Columbia on September 20, 2013 by preferred shareholders against us, FHFA as our conservator, the Director of FHFA (in his official capacity), Treasury, the Secretary of the Treasury (in his official capacity) and Freddie Mac. Plaintiffs bring claims for breach of contract and breach of the implied covenant of good faith and fair dealing against us, FHFA and Freddie Mac, and claims for violation of the Administrative Procedure Act against the FHFA and Treasury defendants, alleging that the net worth sweep dividend provisions nullified certain rights of the preferred shareholders, particularly the right to receive dividends. Plaintiffs seek damages, equitable and injunctive relief, and costs and expenses, including attorneys’ fees.

On September 30, 2014, the court dismissed both lawsuits and plaintiffs in both suits filed timely notices of appeal. On October 27, 2014, the U.S. Court of Appeals for the D.C. Circuit consolidated these appeals with appeals in two other cases involving the same subject matter, but to which we are not a party. The D.C. Circuit heard oral argument on these appeals onApril 15, 2016.

On June 26, 2016, shareholder David J. Voacolo filed a lawsuit, Voacolo v. Fannie Mae, in the U.S. District Court for the District of Columbia against Fannie Mae, FHFA and Treasury alleging a violation of the Administrative Procedure Act. Plaintiff seeks damages and a holding that the August 2012 amendment to the senior preferred stock purchase agreement was arbitrary, capricious or not otherwise in accordance with the law. The defendants filed motions to dismiss on September 20, 2016.

Given the stage of these lawsuits, the substantial and novel legal questions that remain, and our substantial defenses, we are currently unable to estimate the reasonably possible loss or range of loss arising from this litigation.

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

Information about market risk is set forth in “MD&A—Risk Management—Market Risk Management, Including Interest Rate Risk Management.”

Item 4.  Controls and Procedures

Overview

We are required under applicable laws and regulations to maintain controls and procedures, which include disclosure controls and procedures as well as internal control over financial reporting, as further described below.

Evaluation of Disclosure Controls and Procedures

Disclosure Controls and Procedures

Disclosure controls and procedures refer to controls and other procedures designed to provide reasonable assurance that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Disclosure controls and procedures include, without limitation, controls and procedures designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding our required disclosure. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management was required to apply its judgment in evaluating and implementing possible controls and procedures.

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15 under the Exchange Act, management has evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures as in effect as of September 30, 2016, the end of the period covered by this report. As a result of management’s evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective at a reasonable assurance level as of September 30, 2016 or as of the date of filing this report.

Our disclosure controls and procedures were not effective as of September 30, 2016 or as of the date of filing this report because they did not adequately ensure the accumulation and communication to management of information known to FHFA that is needed to meet our disclosure obligations under the federal securities laws. As a result, we were not able to rely upon the disclosure controls and procedures that were in place as of September 30, 2016 or as of the date of this filing, and we continue to have a material weakness in our internal control over financial reporting. This material weakness is described in more detail below under “Description of Material Weakness.” Based on discussions with FHFA and the structural nature of this material weakness, we do not expect to remediate this material weakness while we are under conservatorship.

Description of Material Weakness

The Public Company Accounting Oversight Board’s Auditing Standard No. 5 defines a material weakness as a deficiency or a combination of deficiencies in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis.

Management has determined that we continued to have the following material weakness as of September 30, 2016 and as of the date of filing this report:

• Disclosure Controls and Procedures. We have been under the conservatorship of FHFA since September 6, 2008. Under the GSE Act, FHFA is an independent agency that currently functions as both our conservator and our regulator with respect to our safety, soundness and mission. Because of the nature of the conservatorship under the GSE Act, which places us under the “control” of FHFA (as that term is defined by securities laws), some of the information that we may need to meet our disclosure obligations may be solely within the knowledge of FHFA. As our conservator, FHFA has the power to take actions without our knowledge that could be material to our shareholders and other stakeholders, and could significantly affect our financial performance or our continued existence as an ongoing business. Although we and FHFA attempted to design and implement disclosure policies and procedures that would account for the conservatorship and accomplish the same objectives as a disclosure controls and procedures policy of a typical reporting company, there are inherent structural limitations on our ability to design, implement, test or

139

operate effective disclosure controls and procedures. As both our regulator and our conservator under the GSE Act, FHFA is limited in its ability to design and implement a complete set of disclosure controls and procedures relating to Fannie Mae, particularly with respect to current reporting pursuant to Form 8-K. Similarly, as a regulated entity, we are limited in our ability to design, implement, operate and test the controls and procedures for which FHFA is responsible.

Due to these circumstances, we have not been able to update our disclosure controls and procedures in a manner that adequately ensures the accumulation and communication to management of information known to FHFA that is needed to meet our disclosure obligations under the federal securities laws, including disclosures affecting our condensed consolidated financial statements. As a result, we did not maintain effective controls and procedures designed to ensure complete and accurate disclosure as required by GAAP as of September 30, 2016 or as of the date of filing this report. Based on discussions with FHFA and the structural nature of this weakness, we do not expect to remediate this material weakness while we are under conservatorship.

Mitigating Actions Relating to Material Weakness

As described above under “Description of Material Weakness,” we continue to have a material weakness in our internal control over financial reporting relating to our disclosure controls and procedures. However, we and FHFA have engaged in the following practices intended to permit accumulation and communication to management of information needed to meet our disclosure obligations under the federal securities laws:

• FHFA has established the Division of Conservatorship, which is intended to facilitate operation of the company with the oversight of the conservator.

• We have provided drafts of our SEC filings to FHFA personnel for their review and comment prior to filing. We also have provided drafts of external press releases, statements and speeches to FHFA personnel for their review and comment prior to release.

• FHFA personnel, including senior officials, have reviewed our SEC filings prior to filing, including this Quarterly Report on Form 10-Q for the quarter ended September 30, 2016 (“Third Quarter 2016 Form 10-Q”), and engaged in discussions regarding issues associated with the information contained in those filings. Prior to filing our Third Quarter 2016 Form 10-Q, FHFA provided Fannie Mae management with a written acknowledgment that it had reviewed the Third Quarter 2016 Form 10-Q, and it was not aware of any material misstatements or omissions in the Third Quarter 2016 Form 10-Q and had no objection to our filing the Third Quarter 2016 Form 10-Q.

• The Director of FHFA and our Chief Executive Officer have been in frequent communication, typically meeting on at least a bi-weekly basis.

• FHFA representatives attend meetings frequently with various groups within the company to enhance the flow of information and to provide oversight on a variety of matters, including accounting, credit and market risk management, external communications and legal matters.

• Senior officials within FHFA’s Office of the Chief Accountant have met frequently with our senior finance executives regarding our accounting policies, practices and procedures.

Changes in Internal Control over Financial Reporting

Management has evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, whether any changes in our internal control over financial reporting that occurred during our last fiscal quarter have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. There have been no changes in our internal control over financial reporting since June 30, 2016 that management believes have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1.  Legal Proceedings

The information in this item supplements and updates information regarding certain legal proceedings set forth in “Legal Proceedings” in our 2015 Form 10-K, our First Quarter 2016 Form 10-Q and our Second Quarter 2016 Form 10-Q. We also provide information regarding material legal proceedings in “Note 16, Commitments and Contingencies,” which is incorporated herein by reference. In addition to the matters specifically described or incorporated by reference in this item, we are involved in a number of legal and regulatory proceedings that arise in the ordinary course of business that do not have a material impact on our business. Litigation claims and proceedings of all types are subject to many factors that generally cannot be predicted accurately.

We record accruals for legal claims when losses associated with those claims become probable and the amounts can be reasonably estimated. The actual costs of resolving legal claims may be substantially higher or lower than the amounts accrued for those claims. For matters where the likelihood or extent of a loss is not probable or cannot be reasonably estimated, we do not recognize in our condensed consolidated financial statements the potential liability that may result from these matters. We presently cannot determine the ultimate resolution of the matters described below or incorporated by reference into this item or in our 2015 Form 10-K, our First Quarter 2016 Form 10-Q or our Second Quarter 2016 Form 10-Q. If certain of these matters are determined against us, FHFA or Treasury, it could have a material adverse effect on our results of operations, liquidity and financial condition, including our net worth.

Senior Preferred Stock Purchase Agreements Litigation

Between June 2013 and October 2016, several lawsuits were filed by preferred and common stockholders of Fannie Mae and Freddie Mac in the U.S. Court of Federal Claims, the U.S. District Court for the District of Columbia, the U.S. District Court for the Southern District of Iowa, the U.S. District Court for the Northern District of Iowa, the U.S. District Court for the District of Delaware, the U.S. District Court for the Eastern District of Kentucky, the U.S. District Court for the Northern District of Illinois and the U.S. District Court for the Southern District of Texas against one or more of the United States, Treasury and FHFA, challenging actions taken by the defendants relating to the senior preferred stock purchase agreements and the conservatorships of Fannie Mae and Freddie Mac. Some of these lawsuits also contain claims against Fannie Mae and Freddie Mac. The legal claims being advanced by one or more of these lawsuits include challenges to the net worth sweep dividend provisions of the senior preferred stock that were implemented pursuant to the August 2012 amendments to the agreements, the payment of dividends to Treasury under the net worth sweep dividend provisions, and FHFA’s decision to require Fannie Mae and Freddie Mac to draw funds from Treasury in order to pay dividends to Treasury prior to the August 2012 amendments. The plaintiffs seek various forms of equitable and injunctive relief, including rescission of the August 2012 amendments, as well as damages.

On September 30, 2014, the U.S. District Court for the District of Columbia dismissed all but one of the cases pending before that court. The plaintiffs in each of the dismissed cases filed a notice of appeal and on October 27, 2014, the U.S. Court of Appeals for the D.C. Circuit consolidated these appeals.The plaintiffs in the case that was not dismissed by the court voluntarily dismissed their lawsuit on October 31, 2014. On February 3, 2015, the U.S. District Court for the Southern District of Iowa dismissed the case pending before it. On April 15, 2016, the U.S. Court of Appeals for the D.C. Circuit heard oral argument on the consolidated appeals. On September 9, 2016, the U.S. District Court for the Eastern District of Kentucky dismissed the case pending before it. The matters where Fannie Mae is a named defendant are described below or in “Note 16, Commitments and Contingencies.”

Fannie Mae is a nominal defendant in two actions filed against the United States in the U.S. Court of Federal Claims: Fisher v. United States of America, filed on December 2, 2013, and Rafter v. United States of America, filed on August 14, 2014. Plaintiffs in these cases allege that the net worth sweep dividend provisions of the senior preferred stock that were implemented pursuant to the August 2012 amendment to the senior preferred stock purchase agreement constitute a taking of Fannie Mae’s property without just compensation in violation of the U.S. Constitution. The Fisher plaintiffs are pursuing this claim derivatively on behalf of Fannie Mae, while the Rafter plaintiffs are pursing the claim directly against the United States. Plaintiffs in Rafter also allege a derivative claim that the government breached an implied contract with Fannie Mae’s Board of Directors by implementing the net worth sweep dividend provisions. Plaintiffs in Fisher request just compensation to Fannie Mae in an unspecified amount. Plaintiffs in Rafter seek just compensation for themselves on their constitutional claim and payment of damages to Fannie Mae on their derivative claim for breach of an implied contract. The United States filed a motion to dismiss the Fisher case on January 23, 2014; however, the court has stayed proceedings in this case until discovery in a related case, Fairholme Funds v. United States, is complete and the court sets a date for the Fairholme Funds plaintiffs to respond to the government’s motion to dismiss filed in that case. In the Rafter case, the court has ordered the government to file a response to the complaint within sixty days after discovery is complete in the Fairholme Funds case.

141

Fannie Mae is also a nominal defendant in a case filed against FHFA and Treasury in the U.S. District Court for the District of Delaware: Jacobs v. FHFA, filed on August 17, 2015. The plaintiffs allege that the net worth sweep dividend provisions of the senior preferred stock that were implemented pursuant to the August 2012 amendments to the agreements violate Delaware law. The plaintiffs are pursuing this claim derivatively on behalf of Fannie Mae and directly against the government. The plaintiffs have also alleged direct breach of contract claims and breach of fiduciary duty claims against the government. The government filed motions to dismiss the case on November 13, 2015.

On March 14, 2016, Timothy Pagliara filed a lawsuit against Fannie Mae in the Delaware Court of Chancery: Pagliara v. Federal National Mortgage Association. The plaintiff owns Fannie Mae preferred stock and seeks access to Fannie Mae’s books and records under a provision of Delaware state law. The plaintiff alleges that he is entitled to inspect Fannie Mae’s books and records in order to investigate potential breaches of duties to stockholders related to the net worth sweep dividend provisions of the senior preferred stock that were implemented pursuant to the August 2012 amendment to the senior preferred stock purchase agreement, as well as Fannie Mae’s involvement in the common securitization platform, Common Securitization Solutions, LLC, and the single security. On March 25, 2016, Fannie Mae and FHFA removed the case to the U.S. District Court for the District of Delaware. On July 18, 2016, FHFA filed a motion to substitute itself for the plaintiff.

Item 1A.  Risk Factors

In addition to the information in this report, you should carefully consider the risks relating to our business that we identify in “Risk Factors” in our 2015 Form 10-K. This section supplements and updates that discussion. For a complete understanding of the subject, you should read both together. Please also refer to “MD&A—Risk Management” in this report and in our 2015 Form 10-K for more detailed descriptions of the primary risks to our business and how we seek to manage those risks.

The risks we face could materially adversely affect our business, results of operations, financial condition, liquidity and net worth, and could cause our actual results to differ materially from our past results or the results contemplated by forward-looking statements contained in this report. However, these are not the only risks we face. In addition to the risks we discuss below and in our 2015 Form 10-K, we face risks and uncertainties not currently known to us or that we currently believe are immaterial.

The future of our company is uncertain.

There continues to be significant uncertainty regarding the future of our company, including how long the company will continue to exist in its current form, the extent of our role in the market, how long we will be in conservatorship, what form we will have and what ownership interest, if any, our current common and preferred stockholders will hold in us after the conservatorship is terminated, and whether we will continue to exist following conservatorship. The conservatorship is indefinite in duration and the timing, conditions and likelihood of our emerging from conservatorship are uncertain. Termination of the conservatorship, other than in connection with a receivership, requires Treasury’s consent under the senior preferred stock purchase agreement.

In 2011, the Administration released a report to Congress on ending the conservatorships of the GSEs and reforming America’s housing finance market. The report provides that the Administration will work with FHFA to determine the best way to responsibly reduce Fannie Mae and Freddie Mac’s role in the market and ultimately wind down both institutions. The report emphasizes the importance of proceeding with a careful transition plan and providing the necessary financial support to Fannie Mae and Freddie Mac during the transition period. In 2013, the White House released a paper confirming that a core principle of the Administration’s housing policy priorities is to wind down Fannie Mae and Freddie Mac through a responsible transition. In 2015, the White House reaffirmed the Administration’s view that housing finance reform should include ending Fannie Mae and Freddie Mac’s business model.

Last year, Congress continued to consider legislation that could materially affect our business if enacted. We expect that Congress will continue to hold hearings and consider legislation on the future status of Fannie Mae and Freddie Mac, including proposals that would result in Fannie Mae’s liquidation or dissolution. Congress or FHFA may also consider legislation or regulation aimed at increasing the competition we face, reducing our market share, expanding our obligations to provide funds to Treasury or constraining our business operations. We cannot predict the prospects for the enactment, timing or final content of housing finance reform legislation or other legislation related to our activities. See “Business—Housing Finance Reform” in our 2015 Form 10-K for more information about the Administration’s statements and Congressional proposals regarding housing finance reform.

142

Changes in accounting standards and policies can be difficult to predict and can materially impact how we record and report our financial results.

Our accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. From time to time, the FASB or the SEC changes the financial accounting and reporting standards or the policies that govern the preparation of our financial statements. In addition, FHFA provides guidance that affects our adoption or implementation of financial accounting or reporting standards. These changes can be difficult to predict and expensive to implement, and can materially impact how we record and report our financial condition and results of operations. We could be required to apply new or revised guidance retrospectively, which may result in the revision of prior period financial statements by material amounts. The implementation of new or revised accounting guidance, such as the new impairment guidance issued in June 2016 that is described in “Note 1, Summary of Significant Accounting Policies—New Accounting Guidance,” could have a material adverse effect on our financial results or net worth and result in or contribute to the need for additional draws from Treasury under the senior preferred stock purchase agreement.

Changes in interest rates or our loss of the ability to manage interest rate risk successfully could adversely affect our financial results and condition, and increase interest rate risk.

We fund our operations primarily through the issuance of debt and invest our funds primarily in mortgage-related assets that permit mortgage borrowers to prepay their mortgages at any time. These business activities expose us to market risk, which is the risk of adverse changes in the fair value of financial instruments resulting from changes in market conditions. Our most significant market risks are interest rate risk and prepayment risk. We describe these risks in more detail in “MD&A—Risk Management—Market Risk Management, Including Interest Rate Risk Management” in our 2015 Form 10-K and in this report. Changes in interest rates affect both the value of our mortgage assets and prepayment rates on our mortgage loans.

Changes in interest rates could have a material adverse effect on our business, results of operations, financial condition, liquidity and net worth. Our ability to manage interest rate risk depends on our ability to issue debt instruments with a range of maturities and other features, including call provisions, at attractive rates and to engage in derivatives transactions. We must exercise judgment in selecting the amount, type and mix of debt and derivatives instruments that will most effectively manage our interest rate risk. The amount, type and mix of financial instruments that are available to us may not offset possible future changes in the spread between our borrowing costs and the interest we earn on our mortgage assets.

We mark to market changes in the estimated fair value of our derivatives through our earnings on a quarterly basis, but we do not similarly mark to market changes in some of the financial instruments that generate our interest rate risk exposures. As a result, changes in interest rates, particularly significant changes, can have a significant adverse effect on our earnings and net worth for the quarter in which the changes occur, depending on the nature of the changes and the derivatives we hold at that time. We have experienced significant fair value losses in some periods due to changes in interest rates, and we expect to continue to experience volatility from period to period in our financial results as a result of fair value losses or gains on our derivatives.

Changes in interest rates also can affect our credit losses. When interest rates increase, our credit losses from loans with adjustable payment terms may increase as borrower payments increase at their reset dates, which increases the borrower’s risk of default, particularly for adjustable-rate loans with interest-only features. Rising interest rates may also reduce the opportunity for these borrowers to refinance into a fixed-rate loan. Similarly, many borrowers may have additional debt obligations, such as home equity lines of credit and second liens, that also have adjustable payment terms. If a borrower’s payment on his or her other debt obligations increases due to rising interest rates or a change in amortization, it increases the risk that the borrower may default on a loan we own or guarantee.

While we have not experienced negative interest rates in the United States, some central banks in Europe and Asia have cut interest rates below zero. If U.S. interest rates fell below zero, it could result in significant fair value losses on the derivatives we use to manage interest rate risk, reduce our net interest income and increase our operational risk.

Item 2.  Unregistered Sales of Equity Securities and Use of Proceeds

Recent Sales of Unregistered Securities

Under the terms of our senior preferred stock purchase agreement with Treasury, we are prohibited from selling or issuing our equity interests, other than as required by (and pursuant to) the terms of a binding agreement in effect on September 7, 2008, without the prior written consent of Treasury. During the quarter ended September 30, 2016, we did not sell any equity securities.

143

Information about Certain Securities Issuances by Fannie Mae

Pursuant to SEC regulations, public companies are required to disclose certain information when they incur a material direct financial obligation or become directly or contingently liable for a material obligation under an off-balance sheet arrangement. The disclosure must be made in a current report on Form 8-K under Item 2.03 or, if the obligation is incurred in connection with certain types of securities offerings, in prospectuses for that offering that are filed with the SEC.

Because the securities we issue are exempted securities under the Securities Act of 1933, we do not file registration statements or prospectuses with the SEC with respect to our securities offerings. To comply with the disclosure requirements of Form 8-K relating to the incurrence of material financial obligations, we report our incurrence of these types of obligations either in offering circulars or prospectuses (or supplements thereto) that we post on our website or in a current report on Form 8-K that we file with the SEC, in accordance with a “no-action” letter we received from the SEC staff in 2004. In cases where the information is disclosed in a prospectus or offering circular posted on our website, the document will be posted on our website within the same time period that a prospectus for a non-exempt securities offering would be required to be filed with the SEC.

The website address for disclosure about our debt securities is www.fanniemae.com/debtsearch. From this address, investors can access the offering circular and related supplements for debt securities offerings under Fannie Mae’s universal debt facility, including pricing supplements for individual issuances of debt securities.

Disclosure about our obligations pursuant to some of the MBS we issue, some of which may be off-balance sheet obligations, can be found at www.fanniemae.com/mbsdisclosure. From this address, investors can access information and documents about our MBS, including prospectuses and related prospectus supplements.

We are providing our website address solely for your information. Information appearing on our website is not incorporated into this report.

Our Purchases of Equity Securities

We did not repurchase any of our equity securities during the third quarter of 2016.

Dividend Restrictions

Our payment of dividends is subject to the following restrictions:

Restrictions Relating to Conservatorship. Our conservator announced on September 7, 2008 that we would not pay any dividends on the common stock or on any series of preferred stock, other than the senior preferred stock. In addition, FHFA’s regulations relating to conservatorship and receivership operations prohibit us from paying any dividends while in conservatorship unless authorized by the Director of FHFA. The Director of FHFA has directed us to make dividend payments on the senior preferred stock on a quarterly basis.

Restrictions Under Senior Preferred Stock Purchase Agreement. The senior preferred stock purchase agreement prohibits us from declaring or paying any dividends on Fannie Mae equity securities (other than the senior preferred stock) without the prior written consent of Treasury. In addition, in 2012 the terms of the senior preferred stock purchase agreement and the senior preferred stock were amended to require that we pay Treasury each quarter any dividends declared consisting of the amount, if any, by which our net worth as of the end of the immediately preceding fiscal quarter exceeds an applicable capital reserve amount, which will decrease to zero in 2018. As a result, our net income is not available to common stockholders. For more information on the terms of the senior preferred stock purchase agreement and senior preferred stock, see “Business—Conservatorship and Treasury Agreements—Treasury Agreements—Senior Preferred Stock Purchase Agreement and Related Issuance of Senior Preferred Stock and Common Stock Warrant” in our 2015 Form 10-K.

Additional Restrictions Relating to Preferred Stock. Payment of dividends on our common stock is also subject to the prior payment of dividends on our preferred stock and our senior preferred stock. Payment of dividends on all outstanding preferred stock, other than the senior preferred stock, is also subject to the prior payment of dividends on the senior preferred stock.

Statutory Restrictions. Under GSE Act, FHFA has authority to prohibit capital distributions, including payment of dividends, if we fail to meet our capital requirements. If FHFA classifies us as significantly undercapitalized, approval of the Director of FHFA is required for any dividend payment. Under the GSE Act, we are not permitted to make a capital distribution if, after making the distribution, we would be undercapitalized, except the Director of FHFA may permit us to repurchase shares if the repurchase is made in connection with the issuance of additional shares or obligations in at least an equivalent amount and will reduce our financial obligations or otherwise improve our financial condition.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Organization

We are a stockholder-owned corporation organized and existing under the Federal National Mortgage Association Charter Act (the “Charter Act” or our “charter”). We are a government-sponsored enterprise (“GSE”) and we are subject to government oversight and regulation. Our regulators include the Federal Housing Finance Agency (“FHFA”), the U.S. Department of Housing and Urban Development (“HUD”), the U.S. Securities and Exchange Commission (“SEC”), and the U.S. Department of the Treasury (“Treasury”). The U.S. government does not guarantee our securities or other obligations.

Conservatorship

On September 7, 2008, the Secretary of the Treasury and the Director of FHFA announced several actions taken by Treasury and FHFA regarding Fannie Mae, which included: (1) placing us in conservatorship, and (2) the execution of a senior preferred stock purchase agreement by our conservator, on our behalf, and Treasury, pursuant to which we issued to Treasury both senior preferred stock and a warrant to purchase common stock.

Under the Federal Housing Enterprises Financial Safety and Soundness Act of 1992, as amended by the Federal Housing Finance Regulatory Reform Act of 2008 (together, the “GSE Act”), the conservator immediately succeeded to (1) all rights, titles, powers and privileges of Fannie Mae, and of any stockholder, officer or director of Fannie Mae with respect to Fannie Mae and its assets, and (2) title to the books, records and assets of any other legal custodian of Fannie Mae. The conservator has since delegated specified authorities to our Board of Directors and has delegated to management the authority to conduct our day-to-day operations. The conservator retains the authority to withdraw its delegations at any time.

The conservatorship has no specified termination date and there continues to be significant uncertainty regarding our future, including how long we will continue to exist in our current form, the extent of our role in the market, how long we will be in conservatorship, what form we will have and what ownership interest, if any, our current common and preferred stockholders will hold in us after the conservatorship is terminated and whether we will continue to exist following conservatorship. Under the GSE Act, FHFA must place us into receivership if the Director of FHFA makes a written determination that our assets are less than our obligations or if we have not been paying our debts, in either case, for a period of 60 days. In addition, the Director of FHFA may place us into receivership at his discretion at any time for other reasons set forth in the GSE Act, including if we are critically undercapitalized or if we are undercapitalized and have no reasonable prospect of becoming adequately capitalized. Should we be placed into receivership, different assumptions would be required to determine the carrying value of our assets, which could lead to substantially different financial results. We are not aware of any plans of FHFA to fundamentally change our business model or capital structure in the near term.

Impact of U.S. Government Support

We continue to rely on support from Treasury to eliminate any net worth deficits we may experience in the future, which would otherwise trigger our being placed into receivership. Based on consideration of all the relevant conditions and events affecting our operations, including our reliance on the U.S. government, we continue to operate as a going concern and in accordance with our delegation of authority from FHFA.

We believe that continued federal government support of our business, as well as our status as a GSE, are essential to maintaining our access to debt funding. Changes or perceived changes in federal government support of our business or our status as a GSE could materially and adversely affect our liquidity, financial condition and results of operations.

Pursuant to the senior preferred stock purchase agreement, Treasury has committed to provide us with funding to help us maintain a positive net worth thereby avoiding the mandatory receivership trigger described above. We have received a total of $116.1 billion from Treasury pursuant to the senior preferred stock purchase agreement as of September 30, 2016. The aggregate liquidation preference of the senior preferred stock, including the initial aggregate liquidation preference of $1.0 billion, was $117.1 billion as of September 30, 2016. As of September 30, 2016, the amount of remaining funding available to us under the senior preferred stock purchase agreement was $117.6 billion.

Based on the terms of the senior preferred stock, we paid Treasury a dividend of $2.9 billion on September 30, 2016 based on our net worth of $4.1 billion as of June 30,2016 less the applicable capital reserve amount of $1.2 billion. We expect to pay Treasury an additional dividend of $3.0 billion by December 31, 2016 based on our net worth of $4.2 billion as of September 30, 2016 less the applicable capital reserve amount of $1.2 billion. The capital reserve amount was $1.8 billion for dividend periods in 2015. The capital reserve amount will continue to be reduced by $600 million each year until it reaches zero on January 1, 2018.

Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the SEC’s instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and note disclosures required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments of a normal recurring nature considered necessary for a fair presentation have been included. The accompanying condensed consolidated financial statements include our accounts as well as the accounts of other entities in which we have a controlling financial interest. All intercompany accounts and transactions have been eliminated. To conform to our current period presentation, we have reclassified certain amounts reported in our prior periods’ condensed consolidated financial statements. Results for the nine months ended September 30, 2016 may not necessarily be indicative of the results for the year ending December 31, 2016. The unaudited interim condensed consolidated financial statements as of and for the nine months ended September 30, 2016 should be read in conjunction with our audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2015 (“2015 Form 10-K”), filed with the SEC on February 19, 2016.

Regulatory Capital

FHFA stated that, during conservatorship, our existing statutory and FHFA-directed regulatory capital requirements will not be binding and FHFA will not issue quarterly capital classifications. We submit capital reports to FHFA and FHFA monitors our capital levels. The deficit of core capital over statutory minimum capital was $138.9 billion as of September 30, 2016 and $139.7 billion as of December 31, 2015.

Under the terms of the senior preferred stock, we are required to pay Treasury a dividend each quarter, when, as and if declared, equal to the excess of our net worth as of the end of the preceding quarter over an applicable capital reserve amount. The Director of FHFA has directed us to make dividend payments on the senior preferred stock on a quarterly basis. Therefore, we do not expect to eliminate our deficit of core capital over statutory minimum capital.

Related Parties

As a result of our issuance to Treasury of the warrant to purchase shares of Fannie Mae common stock equal to 79.9% of the total number of shares of Fannie Mae common stock, we and Treasury are deemed related parties. As of September 30, 2016, Treasury held an investment in our senior preferred stock with an aggregate liquidation preference of $117.1 billion. FHFA’s control of both us and Freddie Mac has caused us, FHFA and Freddie Mac to be deemed related parties. In 2013, Fannie Mae and Freddie Mac established Common Securitization Solutions, LLC (“CSS”), a jointly owned limited liability company to operate a common securitization platform; therefore, CSS is deemed a related party.

Transactions with Treasury

Our administrative expenses were reduced by $14 million and $18 million for the three months ended September 30, 2016 and 2015, respectively, and $45 million and $50 million for the nine months ended September 30, 2016 and 2015, respectively, due to reimbursements from Treasury and Freddie Mac for expenses incurred as program administrator for Treasury’s Home Affordable Modification Program (“HAMP”) and other initiatives under Treasury’s Making Home Affordable Program.

During the three and nine months ended September 30, 2016, we made tax payments of $531 million and $1.1 billion, respectively, to the Internal Revenue Service (“IRS”), a bureau of Treasury. We made tax payments of $100 million and $470 million during the three and nine months ended September 30, 2015. We received no refund from the IRS during the nine months ended September 30, 2016. We received a refund of $277 million from the IRS during the nine months ended September 30, 2015 for income tax adjustments related to tax years 2004 through 2010.

In 2009, we entered into a memorandum of understanding with Treasury, FHFA and Freddie Mac pursuant to which we agreed to provide assistance to state and local housing finance agencies (“HFAs”) through different programs, including a new issue bond (“NIB”) program. As of September 30, 2016, under the NIB program, Fannie Mae and Freddie Mac had $6.5 billion outstanding of pass-through securities backed by single-family and multifamily housing bonds issued by HFAs, which is less than 35% of the total original principal under the program, the amount of losses that Treasury would bear. Accordingly, we do not have a potential risk of loss under the NIB program.

The fee revenue and expense related to the Temporary Payroll Tax Cut Continuation Act of 2011 (“TCCA”) are recorded in “Mortgage loans interest income” and “TCCA fees,” respectively, in our condensed consolidated statements of operations and comprehensive income. We recognized $465 million and $413 million in TCCA fees during the three months ended September 30, 2016 and 2015, respectively, and $1.4 billion and $1.2 billion for the nine months ended September 30, 2016 and 2015, respectively, of which $465 million had not been remitted to Treasury as of September 30, 2016.

We incurred expenses in connection with certain funding obligations under the GSE Act, a portion of which is attributable to Treasury’s Capital Magnet and HOPE Funds. These expenses, recognized in “Other expenses, net” in our condensed consolidated statements of operations and comprehensive income, were measured as the product of 4.2 basis points and the unpaid principal balance of our total new business purchases for the respective period. We recognized $40 million and $56 million in other expenses in connection with Treasury’s Capital Magnet and HOPE Funds for the three months ended September 30, 2016 and 2015, respectively, and $96 million and $168 million for the nine months ended September 30, 2016 and 2015, respectively, of which $96 million resulting from 2016 purchases had not been remitted as of September 30, 2016.

In addition to the transactions with Treasury mentioned above, we also purchase and sell Treasury securities in the normal course of business. As of September 30, 2016 and December 31, 2015, we held Treasury securities with a fair value of $31.3 billion and $29.5 billion, respectively, and accrued interest receivable of $28 million and $15 million, respectively. We recognized interest income on these securities held by us of $40 million and $8 million for the three months ended September 30, 2016 and 2015, respectively, and $105 million and $17 million for the nine months ended September 30, 2016 and 2015, respectively.

Transactions with Freddie Mac

As of September 30, 2016 and December 31, 2015, we held Freddie Mac mortgage-related securities with a fair value of $1.4 billion and $5.6 billion, respectively, and accrued interest receivable of $5 million and $22 million, respectively. We recognized interest income on these securities held by us of $19 million and $55 million for the three months ended September 30, 2016 and 2015, respectively, and $100 million and $174 million for the nine months ended September 30, 2016 and 2015, respectively. In addition, Freddie Mac may be an investor in variable interest entities (“VIEs”) that we have consolidated, and we may be an investor in VIEs that Freddie Mac has consolidated.

Transactions with FHFA

The GSE Act authorizes FHFA to establish an annual assessment for regulated entities, including Fannie Mae, which is payable on a semi-annual basis (April and October), for FHFA’s costs and expenses, as well as to maintain FHFA’s working capital. We recognized FHFA assessment fees, which are recorded in “Administrative expenses” in our condensed consolidated statements of operations and comprehensive income, of $28 million for the three months ended September 30, 2016 and 2015, and $84 million for the nine months ended September 30, 2016 and 2015.

Transactions with CSS

In connection with our jointly owned company with Freddie Mac, we contributed $23 million and $17 million for the three months ended September 30, 2016 and 2015, respectively, and $88 million and $47 million for the nine months ended September 30, 2016 and 2015, respectively, of capital into CSS. No other transactions outside of normal business activities have occurred between us and CSS during the nine months ended September 30, 2016 and 2015.

Use of Estimates

Preparing condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect our reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities as of the dates of our condensed consolidated financial statements, as well as our reported amounts of revenues and expenses during the reporting periods. Management has made significant estimates in a variety of areas including, but not limited to, valuation of certain financial instruments and other assets and liabilities and allowance for loan losses. Actual results could be different from these estimates.

On January 1, 2015, we adopted regulatory guidance issued by FHFA which prescribes, among other things, guidance on when a loan should be charged off. This change in estimate resulted in the recognition on January 1, 2015 of (1) $1.8 billion in charge-offs of held for investment loans, (2) $724 million in charge-offs of preforeclosure property taxes and insurance receivable and (3) a reduction to our allowance for loan losses and our allowance for preforeclosure property taxes and insurance receivable in amounts equal to charge-offs recognized in connection with held for investment loans and preforeclosure property taxes and insurance receivable.

For the majority of our delinquent single-family loans, we charge off the loan at the date of foreclosure or other liquidation event (such as a deed-in-lieu of foreclosure or a short sale). For a subset of delinquent single-family loans, we charge off the portion of the loans that is deemed uncollectible prior to foreclosure when the loans have been delinquent for a specified length of time and meet specified mark-to-market loan-to-value (“LTV”) ratios. We continue to enhance our data collection and analysis efforts to further refine our loss estimates as we obtain incremental information on the performance of our loans.

Debt

We issue debt in the form of credit risk transfer notes under the Connecticut Avenue Securities (“CAS”) program where repayment of the debt is linked to a reference portfolio of mortgage loans. We account for CAS debt issued in 2016 at amortized cost. As credit events occur and the principal balance of the CAS debt is legally reduced, we recognize an extinguishment gain. We elected the fair value option on CAS debt that was issued prior to 2016.

New Accounting Guidance

Effective January 1, 2016, we adopted guidance regarding consolidation of legal entities such as limited partnerships, limited liability corporations and securitization structures. The impact of the adoption was not material to our condensed consolidated financial statements.

In February 2016, the Financial Accounting Standards Board (“FASB”) issued guidance on leases. The guidance clarified the definition of a lease and requires lessees to recognize on the balance sheet a right-of-use asset, representing its right to use the underlying asset for the lease term, and a corresponding lease liability for all leases with terms greater than 12 months. This guidance supersedes the existing lease guidance; however, we must continue to classify leases to determine how to recognize lease-related expense in our condensed consolidated statements of operations and comprehensive income. The new guidance is effective for us on January 1, 2019. We have evaluated this guidance and determined it will not have a material impact on our condensed consolidated financial statements.

In June 2016, FASB issued guidance that changes the impairment model for most financial assets and certain other instruments. For loans, held-to-maturity debt securities and other financial assets recorded at amortized cost, entities will be required to use a new forward-looking “expected loss” model that will replace today’s “incurred loss” model and generally will result in the earlier recognition of allowances for losses. The guidance is effective on January 1, 2020 with early adoption permitted on January 1, 2019. We will recognize the impact of the new guidance through a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements and the timing of our adoption.

In August 2016, FASB issued guidance regarding classification of certain items within the statement of cash flows in order to reduce diversity in practice with respect to cash flow classifications. The guidance is effective for us on January 1, 2018 and will be applied retrospectively for each period presented. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements.

Consolidations and Transfers of Financial Assets [Abstract]

Consolidations and Transfers of Financial Assets

Consolidations and Transfers of Financial Assets

We have interests in various entities that are considered to be VIEs. The primary types of entities are securitization trusts guaranteed by us via lender swap and portfolio securitization transactions and mortgage-backed trusts that were not created by us, as well as housing partnerships that are established to finance the acquisition, construction, development or rehabilitation of affordable multifamily and single-family housing. These interests include investments in securities issued by VIEs, such as Fannie Mae MBS created pursuant to our securitization transactions and our guaranty to the entity. We consolidate the substantial majority of our single-class securitization trusts because our role as guarantor and master servicer provides us with the power to direct matters (primarily the servicing of mortgage loans) that impact the credit risk to which we are exposed. In contrast, we do not consolidate single-class securitization trusts when other organizations have the power to direct these activities.

We continually assess whether we are the primary beneficiary of the VIEs with which we are involved and therefore may consolidate or deconsolidate a VIE through the duration of our involvement. Examples of certain events that may change whether or not we consolidate the VIE include a change in the design of the entity or a change in our ownership in the entity such that we no longer hold substantially all of the certificates issued by a multi-class securitization trust. As of September 30, 2016, we consolidated certain VIEs that were not consolidated as of December 31, 2015. As a result of consolidating these entities, which had combined total assets of $154 million in unpaid principal balance as of September 30, 2016, we derecognized our investment in these entities and recognized the assets and liabilities of the consolidated entities at fair value. As of September 30, 2016, we also deconsolidated certain VIEs that were consolidated as of December 31, 2015. As a result of deconsolidating these entities, which had combined total assets of $5.3 billion in unpaid principal balance as of December 31, 2015, we derecognized the assets and liabilities of the entities and recognized at fair value our retained interests as securities in our condensed consolidated balance sheets.

Unconsolidated VIEs

We do not consolidate VIEs when we are not deemed to be the primary beneficiary. Our unconsolidated VIEs include securitization trusts and limited partnerships. The following table displays the carrying amount and classification of our assets and liabilities that relate to our involvement with unconsolidated mortgage-backed trusts.

	As of
	September 30, 2016				December 31, 2015
	(Dollars in millions)
Assets and liabilities recorded in our condensed consolidated balance sheets related to mortgage-backed trusts:
Assets:
Trading securities:
Fannie Mae		$	4,793			$	4,704
Non-Fannie Mae		4,336				5,596
Total trading securities		9,129				10,300
Available-for-sale securities:
Fannie Mae		2,601				3,936
Non-Fannie Mae		6,106				14,644
Total available-for-sale securities		8,707				18,580
Other assets		67				100
Other liabilities		(450		)		(827		)
Net carrying amount		$	17,453			$	28,153

Our maximum exposure to loss generally represents the greater of our recorded investment in the entity or the unpaid principal balance of the assets covered by our guaranty. However, our securities issued by Fannie Mae multi-class resecuritization trusts that are not consolidated do not give rise to any additional exposure to loss as we already consolidate the underlying collateral. The maximum exposure to loss related to unconsolidated mortgage-backed trusts was approximately $24 billion and $34 billion as of September 30, 2016 and December 31, 2015, respectively. The total assets of our unconsolidated mortgage-backed trusts were approximately $170 billion and $220 billion as of September 30, 2016 and December 31, 2015, respectively.

The maximum exposure to loss for our unconsolidated limited partnerships and similar legal entities, which consist of low-income housing tax credit investments, community investments and other entities, was $123 million and the related carrying value was $92 million as of September 30, 2016. As of December 31, 2015, the maximum exposure to loss was $12 million and the related carrying value was a deficit of $24 million. The total assets of these limited partnership investments were $4.0 billion and $4.9 billion as of September 30, 2016 and December 31, 2015, respectively.

The unpaid principal balance of our multifamily loan portfolio was $221.9 billion as of September 30, 2016. As our lending relationship does not provide us with a controlling financial interest in the borrower entity, we do not consolidate these borrowers regardless of their status as either a VIE or a voting interest entity. We have excluded these entities from our VIE disclosures. However, the disclosures we have provided in “Note 3, Mortgage Loans,” “Note 4, Allowance for Loan Losses” and “Note 6, Financial Guarantees” with respect to this population are consistent with the FASB’s stated objectives for the disclosures related to unconsolidated VIEs.

Transfers of Financial Assets

We issue Fannie Mae MBS through portfolio securitization transactions by transferring pools of mortgage loans or mortgage-related securities to one or more trusts or special purpose entities. We are considered to be the transferor when we transfer assets from our own retained mortgage portfolio in a portfolio securitization transaction. For the three months ended September 30, 2016 and 2015, the unpaid principal balance of portfolio securitizations was $76.1 billion and $55.4 billion, respectively. For the nine months ended September 30, 2016 and 2015, the unpaid principal balance of portfolio securitizations was $188.7 billion and $166.3 billion, respectively.

We retain interests from the transfer and sale of mortgage-related securities to unconsolidated single-class and multi-class portfolio securitization trusts. As of September 30, 2016, the unpaid principal balance of retained interests was $4.5 billion and its related fair value was $6.0 billion. The unpaid principal balance of retained interests was $5.5 billion and its related fair value was $6.8 billion as of December 31, 2015. For the three months ended September 30, 2016 and 2015, the principal and interest received on retained interests was $284 million and $273 million, respectively. For the nine months ended September 30, 2016 and 2015, the principal and interest received on retained interests was $907 million and $919 million, respectively.

Managed Loans

Managed loans are on-balance sheet mortgage loans, as well as mortgage loans that we have securitized in unconsolidated portfolio securitization trusts. The unpaid principal balance of securitized loans in unconsolidated portfolio securitization trusts, which are primarily loans that are guaranteed or insured, in whole or in part, by the U.S. government, was $1.4 billion and $1.6 billion as of September 30, 2016 and December 31, 2015, respectively. For information on our on-balance sheet mortgage loans, see “Note 3, Mortgage Loans.”

Mortgage Loans on Real Estate [Abstract]

Mortgage Loans

Mortgage Loans

We own single-family mortgage loans, which are secured by four or fewer residential dwelling units, and multifamily mortgage loans, which are secured by five or more residential dwelling units. We classify these loans as either held for investment (“HFI”) or held for sale (“HFS”). We report the carrying value of HFI loans at the unpaid principal balance, net of unamortized premiums and discounts, other cost basis adjustments, and an allowance for loan losses. We report the carrying value of HFS loans at the lower of cost or fair value and record valuation changes in “Investment gains, net” in our condensed consolidated statements of operations and comprehensive income. We define the recorded investment of HFI loans as unpaid principal balance, net of unamortized premiums and discounts, other cost basis adjustments, and accrued interest receivable.

For purposes of the single-family mortgage loan disclosures below, we define “primary” class as mortgage loans that are not included in other loan classes; “government” class as mortgage loans guaranteed or insured, in whole or in part, by the U.S. government or one of its agencies, that are not Alt-A; and “other” class as loans with higher-risk characteristics, such as interest-only loans and negative-amortizing loans, that are neither government nor Alt-A.

The following table displays the carrying value of our mortgage loans.

	As of
	September 30, 2016												December 31, 2015
	Of Fannie Mae				Of Consolidated Trusts				Total				Of Fannie Mae				Of Consolidated Trusts				Total

During the three and nine months ended September 30, 2016, we redesignated loans with a carrying value of $652 million and $2.3 billion, respectively, from HFI to HFS. During the three and nine months ended September 30, 2015, we redesignated loans with a carrying value of $1.3 billion and $5.9 billion, respectively, from HFI to HFS. We sold loans with an unpaid principal balance of $1.6 billion and $4.2 billion during the three and nine months ended September 30, 2016, respectively. We sold loans with an unpaid principal balance of $1.9 billion and $2.5 billion during the three and nine months ended September 30, 2015, respectively.

The recorded investment of single-family mortgage loans for which formal foreclosure proceedings are in process was $19.5 billion and $25.6 billion as of September 30, 2016 and December 31, 2015, respectively. As a result of our various loss mitigation and foreclosure prevention efforts, we expect that a portion of the loans in the process of formal foreclosure proceedings will not ultimately foreclose.

Nonaccrual Loans

We discontinue accruing interest on loans when we believe collectibility of principal or interest is not reasonably assured, which for a single-family loan we have determined, based on our historical experience, to be when the loan becomes two months or more past due according to its contractual terms. Interest previously accrued but not collected is reversed through interest income at the date a loan is placed on nonaccrual status. We return a non-modified single-family loan to accrual status at the point that the borrower brings the loan current. We return a modified single-family loan to accrual status at the point that the borrower successfully makes all required payments during the trial period (generally three to four months) and the modification is made permanent. We place a multifamily loan on nonaccrual status when the loan becomes three months or more past due according to its contractual terms or is deemed to be individually impaired, unless the loan is well secured such that collectibility of principal and accrued interest is reasonably assured. We return a multifamily loan to accrual status when the borrower cures the delinquency of the loan or we otherwise determine that the loan is well secured such that collectibility is reasonably assured.

Individually Impaired Loans

Individually impaired loans include troubled debt restructurings (“TDRs”), acquired credit-impaired loans and multifamily loans that we have assessed as probable that we will not collect all contractual amounts due, regardless of whether we are currently accruing interest; excluding loans classified as HFS. The following tables display the total unpaid principal balance, recorded investment, related allowance, average recorded investment and interest income recognized for individually impaired loans.

Troubled Debt Restructurings

A modification to the contractual terms of a loan that results in granting a concession to a borrower experiencing financial difficulties is considered a TDR. In addition to formal loan modifications, we also engage in other loss mitigation activities with troubled borrowers, which include repayment plans and forbearance arrangements, both of which represent informal agreements with the borrower that do not result in the legal modification of the loan’s contractual terms. We account for these informal restructurings as a TDR if we defer more than three missed payments. We also classify loans to certain borrowers who have received bankruptcy relief as TDRs.

The substantial majority of the loan modifications we complete result in term extensions, interest rate reductions or a combination of both. During the three months ended September 30, 2016 and 2015, the average term extension of a single-family modified loan was 153 months and 159 months, respectively, and the average interest rate reduction was 0.82 and 0.69 percentage points, respectively. During the nine months ended September 30, 2016 and 2015, the average term extension of a single-family modified loan was 157 months and 161 months, respectively, and the average interest rate reduction was 0.76 and 0.75 percentage points, respectively.

Allowance for Loan Losses

Receivables [Abstract]

Allowance for Loan Losses

Allowance for Loan Losses

We maintain an allowance for loan losses for HFI loans held by Fannie Mae and loans backing Fannie Mae MBS issued from consolidated trusts. When calculating our allowance for loan losses, we consider our net recorded investment in the loan at the balance sheet date, which includes unpaid principal balance, net of amortized premiums and discounts, and other cost basis adjustments. We record charge-offs as a reduction to the allowance for loan losses when losses are confirmed through the receipt of assets in full satisfaction of a loan, such as the underlying collateral upon foreclosure or cash upon completion of a short sale. Additionally, we record charge-offs as a reduction to our allowance for loan losses when a loan is determined to be uncollectible or upon the redesignation of nonperforming loans from HFI to HFS.

We aggregate single-family HFI loans that are not individually impaired based on similar risk characteristics for purposes of estimating incurred credit losses and establishing a collective single-family loss reserve using an econometric model that derives an overall loss reserve estimate. We base our allowance methodology on historical events and trends, such as loss severity (in event of default), default rates, and recoveries from mortgage insurance contracts and other credit enhancements. In addition, management performs a review of the observable data used in its estimate to ensure it is representative of prevailing economic conditions and other events existing as of the balance sheet date.

Individually impaired single-family loans currently include those restructured in a TDR and acquired credit-impaired loans. When a loan has been restructured, we measure impairment using a cash flow analysis discounted at the loan’s original effective interest rate. However, if we expect to recover our recorded investment in an individually impaired loan through probable foreclosure of the underlying collateral, we measure impairment based on the fair value of the collateral, reduced by estimated disposal costs and adjusted for estimated proceeds from mortgage, flood, or hazard insurance and other credit enhancements.

We identify multifamily loans for evaluation for impairment through a credit risk assessment process. If we determine that a multifamily loan is individually impaired, we generally measure impairment on that loan based on the fair value of the underlying collateral less estimated costs to sell the property. We establish a collective loss reserve for all loans in our multifamily guaranty book of business that are not individually impaired using an internal model that applies loss factors to loans in similar risk categories. Our loss factors are developed based on our historical default and loss severity experience.

The following tables display changes in single-family, multifamily and total allowance for loan losses.

⁽¹⁾  Provision (benefit) for loan losses is included in “Benefit for credit losses” in our condensed consolidated statements of operations and comprehensive income.

⁽²⁾  While we purchase the substantial majority of loans that are four or more months delinquent from our MBS trusts, we do not exercise this option to purchase loans during a forbearance period. Charge-offs of consolidated trusts generally represent loans that remained in our consolidated trusts at the time of default.

⁽³⁾  Our charge-offs for 2015 include the initial charge-offs associated with our approach to adopting the charge-off provisions of Advisory Bulletin AB 2012-02, “Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention,” as well as charge-offs relating to a change in accounting policy for nonaccrual loans.

⁽⁴⁾  Includes transfers from trusts for delinquent loan purchases.

⁽⁵⁾  Amounts represent changes in other loss reserves which are reflected in provision (benefit) for loan losses, charge-offs, and recoveries.

We recognized $3 million and $5 million of OTTI for the three months ended September 30, 2016 and 2015, respectively, and $34 million and $187 million of OTTI for the nine months ended September 30, 2016 and 2015, respectively, which are included in “Investment gains, net” in our condensed consolidated statements of operations and comprehensive income.

The following table displays the modeled attributes, including default rates and severities, which were used to determine as of September 30, 2016 whether our senior interests in certain non-agency mortgage-related securities (including those we intend to sell) will experience a cash shortfall. An estimate of voluntary prepayment rates is also an input to the present value of expected losses.

Guarantees [Abstract]

Financial Guarantees

Financial Guarantees

We recognize a guaranty obligation for our obligation to stand ready to perform on our guarantees to unconsolidated trusts and other guaranty arrangements. These guarantees expose us to credit losses on the mortgage loans or, in the case of mortgage-related securities, the underlying mortgage loans of the related securities. The remaining contractual terms of our guarantees range from 1 day to 36 years; however, the actual term of each guaranty may be significantly less than the contractual term based on the prepayment characteristics of the related mortgage loans.

The following table displays our maximum exposure, guaranty obligation recognized in our condensed consolidated balance sheets and the maximum potential recovery from third parties through available credit enhancements and recourse related to our financial guarantees.

⁽¹⁾  Primarily consists of the unpaid principal balance of the underlying mortgage loans.

⁽²⁾  Recoverability of such credit enhancements and recourse is subject to, among other factors, our mortgage insurers’ and financial guarantors’ ability to meet their obligations to us. For information on our mortgage insurers, see “Note 13, Concentrations of Credit Risk.”

⁽³⁾  Primarily consists of credit enhancements and long-term standby commitments.

The fair value of our guaranty obligations associated with the Fannie Mae MBS included in “Investments in securities” in our condensed consolidated balance sheets was $433 million and $488 million as of September 30, 2016 and December 31, 2015, respectively. These Fannie Mae MBS consist primarily of private-label wraps where our guaranty arrangement is with an unconsolidated MBS trust.

We use a secured intraday funding line of credit provided by a large financial institution. We post collateral which, in some circumstances, the secured party has the right to repledge to third parties. As this line of credit is an uncommitted intraday loan facility, we may be unable to draw on it if and when needed.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

Derivative Instruments

Derivative instruments are an integral part of our strategy in managing interest rate risk. Derivative instruments may be privately-negotiated, bilateral contracts, or they may be listed and traded on an exchange. We refer to our derivative transactions made pursuant to bilateral contracts as our over-the-counter (“OTC”) derivative transactions and our derivative transactions accepted for clearing by a derivatives clearing organization as our cleared derivative transactions. We typically do not settle the notional amount of our risk management derivatives; rather, notional amounts provide the basis for calculating actual payments or settlement amounts. The derivatives we use for interest rate risk management purposes consist primarily of interest rate swaps and interest rate options.

We enter into various forms of credit risk sharing agreements, including credit risk transfer transactions, swap credit enhancements and mortgage insurance contracts, that we account for as derivatives. The majority of our credit-related derivatives are credit risk transfer transactions, whereby a portion of the credit risk associated with losses on a reference pool of mortgage loans is transferred to a third party.

We enter into forward purchase and sale commitments that lock in the future delivery of mortgage loans and mortgage-related securities at a fixed price or yield. Certain commitments to purchase mortgage loans and purchase or sell mortgage-related securities meet the criteria of a derivative. We typically settle the notional amount of our mortgage commitments that are accounted for as derivatives.

We recognize all derivatives as either assets or liabilities in our condensed consolidated balance sheets at their fair value on a trade date basis. Fair value amounts, which are netted to the extent a legal right of offset exists and is enforceable by law at the counterparty level and are inclusive of the right or obligation associated with the cash collateral posted or received, are recorded in “Other assets” or “Other liabilities” in our condensed consolidated balance sheets. See “Note 15, Fair Value” for additional information on derivatives recorded at fair value. We present cash flows from derivatives as operating activities in our condensed consolidated statements of cash flows.

Notional and Fair Value Position of our Derivatives

The following table displays the notional amount and estimated fair value of our asset and liability derivative instruments.

⁽²⁾  The netting adjustment represents the effect of the legal right to offset under legally enforceable master netting arrangements to settle with the same counterparty on a net basis, including cash collateral posted and received. Cash collateral posted was $6.7 billion and $4.9 billion as of September 30, 2016 and December 31, 2015, respectively. Cash collateral received was $419 million and $314 million as of September 30, 2016 and December 31, 2015, respectively.

A majority of our OTC derivative contracts contain provisions that require our senior unsecured debt to maintain a minimum credit rating from S&P and Moody’s. If our senior unsecured debt credit ratings were downgraded to established thresholds in these derivative contracts, which range from A+ to BBB+, we could be required to provide additional collateral to or terminate transactions with certain counterparties. The aggregate fair value of all OTC derivatives with credit-risk-related contingent features that were in a net liability position was $3.3 billion and $2.4 billion as of September 30, 2016 and December 31, 2015, respectively, for which we posted collateral of $3.3 billion and $2.2 billion in the normal course of business as of September 30, 2016 and December 31, 2015, respectively. Had all of the credit-risk-related contingency features underlying these agreements been triggered, an additional $85 million and $257 million would have been required to be posted as collateral or to immediately settle our positions based on the individual agreements and our fair value position as of September 30, 2016 and December 31, 2015, respectively. A reduction in our credit ratings may also cause derivatives clearing organizations or their members to demand that we post additional collateral for our cleared derivatives contracts.

We record all derivative gains and losses, including accrued interest, in “Fair value losses, net” in our condensed consolidated statements of operations and comprehensive income. The following table displays, by type of derivative instrument, the fair value gains and losses, net on our derivatives.

Derivative Counterparty Credit Exposure

Our derivative counterparty credit exposure relates principally to interest rate derivative contracts. We are exposed to the risk that a counterparty in a derivative transaction will default on payments due to us, which may require us to seek a replacement derivative from a different counterparty. This replacement may be at a higher cost, or we may be unable to find a suitable replacement. We manage our derivative counterparty credit exposure relating to our risk management derivative transactions mainly through enforceable master netting arrangements, which allow us to net derivative assets and liabilities with the same counterparty or clearing organization and clearing member. For our OTC derivative transactions, we require counterparties to post collateral, which may include cash, U.S. Treasury securities, agency debt and agency mortgage-related securities.

See “Note 14, Netting Arrangements” for information on our rights to offset assets and liabilities.

Earnings (Loss) Per Share

The calculation of income available to common stockholders and earnings per share is based on the underlying premise that all income after payment of dividends on preferred shares is available to and will be distributed to common stockholders. However, as a result of our conservatorship status and the terms of the senior preferred stock, no amounts are available to distribute as dividends to common or preferred stockholders (other than to Treasury as holder of the senior preferred stock).

The following table displays the computation of basic and diluted earnings (loss) per share of common stock.

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

Our three reportable segments are: Single-Family, Multifamily and Capital Markets. We use these three segments to generate revenue and manage business risk, and each segment is based on the type of business activities it performs. Under our segment reporting, the sum of the results for our three business segments does not equal our condensed consolidated statements of operations and comprehensive income as we separate the activity related to our consolidated trusts from the results generated by our three segments. Our business segment financial results include directly attributable revenues and expenses. We apply accounting methods for segment reporting purposes that differ from our condensed consolidated results. Additionally, we allocate to each of our segments: (1) capital using FHFA minimum capital requirements adjusted for over- or under-capitalization; (2) indirect administrative costs; and (3) a provision for federal income taxes. In addition, we allocate intracompany guaranty fee income as a charge from the Single-Family and Multifamily segments to Capital Markets for managing the credit risk on mortgage loans held by the Capital Markets group. Therefore, we reconcile the sum of the results for our three business segments to our condensed consolidated results of operations.

Risks and Uncertainties [Abstract]

Concentrations of Credit Risk

Concentrations of Credit Risk

Risk Characteristics of our Guaranty Book of Business

We gauge our performance risk under our guaranty based on the delinquency status of the mortgage loans we hold in our retained mortgage portfolio, or in the case of mortgage-backed securities, the mortgage loans underlying the related securities.

For single-family loans, management monitors the serious delinquency rate, which is the percentage of single-family loans 90 days or more past due or in the foreclosure process, and loans that have higher risk characteristics, such as high mark-to-market LTV ratios.

For multifamily loans, management monitors the serious delinquency rate, which is the percentage of loans, based on unpaid principal balance, that are 60 days or more past due, and other loans that have higher risk characteristics, to determine our overall credit quality indicator. Higher risk characteristics include, but are not limited to, current debt service coverage ratio (“DSCR”) below 1.0 and high original LTV ratios. We stratify multifamily loans into different internal risk categories based on the credit risk inherent in each individual loan.

For single-family and multifamily loans, we use this information, in conjunction with housing market and economic conditions, to structure our pricing and our eligibility and underwriting criteria to reflect the current risk of loans with these higher-risk characteristics, and in some cases we decide to significantly reduce our participation in riskier loan product categories. Management also uses this data together with other credit risk measures to identify key trends that guide the development of our loss mitigation strategies.

The following tables display the delinquency status and serious delinquency rates for specified loan categories of our single-family conventional and total multifamily guaranty book of business.

Although we use the most recently available results of our multifamily borrowers, there is a lag in reporting, which typically can range from 3 to 6 months but in some cases may be longer.

Other Concentrations

Mortgage Sellers and Servicers.  Mortgage servicers collect mortgage and escrow payments from borrowers, pay taxes and insurance costs from escrow accounts, monitor and report delinquencies, and perform other required activities on our behalf. Our mortgage sellers and servicers may also be obligated to repurchase loans or foreclosed properties, reimburse us for losses or provide other remedies under certain circumstances, such as if it is determined that the mortgage loan did not meet our underwriting or eligibility requirements, if certain loan representations and warranties are violated or if mortgage insurers rescind coverage. However, under our revised representation and warranty framework, we no longer require repurchase for loans that have breaches of certain selling representations and warranties if they have met specified criteria for relief. Our business with mortgage servicers is concentrated. Our five largest single-family mortgage servicers, including their affiliates, serviced approximately 40% of our single-family guaranty book of business as of September 30, 2016, compared with approximately 44% as of December 31, 2015. Our five largest multifamily mortgage servicers, including their affiliates, serviced approximately 46% of our multifamily guaranty book of business as of September 30, 2016, compared with approximately 45% as of December 31, 2015.

If a significant mortgage seller or servicer counterparty, or a number of mortgage sellers or servicers, fails to meet their obligations to us, it could result in an increase in our credit losses and credit-related expense, and have a material adverse effect on our results of operations, liquidity, financial condition and net worth.

Mortgage Insurers.  Mortgage insurance “risk in force” generally represents our maximum potential loss recovery under the applicable mortgage insurance policies. We had total mortgage insurance coverage risk in force of $124.2 billion and $117.9 billion on the single-family mortgage loans in our guaranty book of business as of September 30, 2016 and December 31, 2015, respectively, which represented 4% of our single-family guaranty book of business as of September 30, 2016 and December 31, 2015. Our primary mortgage insurance coverage risk in force was $123.6 billion and $117.2 billion as of September 30, 2016 and December 31, 2015, respectively. Our pool mortgage insurance coverage risk in force was $646 million and $736 million as of September 30, 2016 and December 31, 2015, respectively. Our top four mortgage insurance companies provided 77% and 79% of our mortgage insurance coverage risk in force as of September 30, 2016 and December 31, 2015, respectively.

Of our largest primary mortgage insurers, PMI Mortgage Insurance Co., Triad Guaranty Insurance Corporation and Republic Mortgage Insurance Company are under various forms of supervised control by their state regulators and are in run-off. Entering run-off may close off a source of profits and liquidity that may have otherwise assisted a mortgage insurer in paying claims under insurance policies, and could also cause the quality and speed of its claims processing to deteriorate. These three mortgage insurers provided a combined $8.5 billion, or 7%, of our risk in force mortgage insurance coverage of our single-family guaranty book of business as of September 30, 2016.

Although the financial condition of our mortgage insurer counterparties currently approved to write new business has improved in recent years, there is still risk that these counterparties may fail to fulfill their obligations to pay our claims under insurance policies. If we determine that it is probable that we will not collect all of our claims from one or more of our mortgage insurer counterparties, it could result in an increase in our loss reserves, which could adversely affect our results of operations, liquidity, financial condition and net worth.

When we estimate the credit losses that are inherent in our mortgage loans and under the terms of our guaranty obligations we also consider the recoveries that we will receive on primary mortgage insurance, as mortgage insurance recoveries would reduce the severity of the loss associated with defaulted loans. We evaluate the financial condition of our mortgage insurer counterparties and adjust the contractually due recovery amounts to ensure that only probable losses as of the balance sheet date are included in our loss reserve estimate. As a result, if our assessment of one or more of our mortgage insurer counterparties’ ability to fulfill their respective obligations to us worsens, it could result in an increase in our loss reserves. As of September 30, 2016 and December 31, 2015, the amount by which our estimated benefit from mortgage insurance reduced our total loss reserves was $1.5 billion and $2.3 billion, respectively.

We had outstanding receivables of $1.0 billion recorded in “Other assets” in our condensed consolidated balance sheets as of September 30, 2016 and $1.2 billion as of December 31, 2015 related to amounts claimed on insured, defaulted loans excluding government insured loans. Of this amount, $135 million as of September 30, 2016 and $241 million as of December 31, 2015 was due from our mortgage sellers or servicers. We assessed the total outstanding receivables for collectibility, and they are recorded net of a valuation allowance of $658 million as of September 30, 2016 and $770 million as of December 31, 2015. The valuation allowance reduces our claim receivable to the amount which is considered probable of collection as of September 30, 2016 and December 31, 2015.

__________

⁽¹⁾  Represents the effect of the right to offset under legally enforceable master netting arrangements to settle with the same counterparty on a net basis, including cash collateral posted and received and accrued interest.

⁽²⁾  Mortgage commitment derivative amounts reflect where we have recognized both an asset and a liability with the same counterparty under an enforceable master netting arrangement but we have not elected to offset the related amounts in our condensed consolidated balance sheets.

⁽³⁾  Represents non-cash collateral received that has not been recognized and not offset in our condensed consolidated balance sheets as well as non-cash collateral posted which has been recognized but not offset in our condensed consolidated balance sheets. Does not include collateral held or posted in excess of our exposure. The fair value of non-cash collateral we pledged was $1.2 billion and $197 million as of September 30, 2016 and December 31, 2015, respectively, which the counterparty was permitted to sell or repledge. The fair value of non-cash collateral received was $40.7 billion and $38.0 billion, of which $37.4 billion and $36.2 billion could be sold or repledged as of September 30, 2016 and December 31, 2015, respectively. None of the underlying collateral was sold or repledged as of September 30, 2016 and December 31, 2015.

⁽⁴⁾  Excludes derivative assets of $23 million and $28 million as of September 30, 2016 and December 31, 2015, and derivative liabilities of $1 million and $2 million recognized in our condensed consolidated balance sheets as of September 30, 2016 and December 31, 2015, respectively, that are not subject to enforceable master netting arrangements.

⁽⁵⁾  Includes $22.3 billion and $10.6 billion of securities purchased under agreements to resell classified as “Cash and cash equivalents” in our condensed consolidated balance sheets as of September 30, 2016 and December 31, 2015, respectively.

Derivative instruments are recorded at fair value and securities purchased under agreements to resell or similar arrangements are recorded at amortized cost in our condensed consolidated balance sheets.

We determine our rights to offset the assets and liabilities presented above with the same counterparty, including collateral posted or received, based on the contractual arrangements entered into with our individual counterparties and various rules and regulations that would govern the insolvency of a derivative counterparty. The following is a description, under various agreements, of the nature of those rights and their effect or potential effect on our financial position.

The terms of the majority of our contracts for OTC risk management derivatives are governed under master agreements of the International Swaps and Derivatives Association Inc. (“ISDA”). These agreements provide that all transactions entered into under the agreement with the counterparty constitute a single contractual relationship. An event of default by the counterparty allows the early termination of all outstanding transactions under the same ISDA agreement and we may offset all outstanding amounts related to the terminated transactions including collateral posted or received.

The terms of our contracts for cleared derivatives are governed under the rules of the clearing organization and the agreement between us and the clearing member of that clearing organization. In the event of a clearing organization default, all open positions at the clearing organization are closed and a net position (on a clearing member by clearing member basis) is calculated. Unless otherwise transferred, in the event of a clearing member default, all open positions cleared through that clearing member are closed and a net position is calculated.

The terms of our contracts for mortgage commitment derivatives are primarily governed by the Fannie Mae Single-Family Selling Guide (“Guide”), for Fannie Mae-approved lenders, or Master Securities Forward Transaction Agreements (“MSFTA”), for counterparties that are not Fannie Mae-approved lenders. In the event of default by the counterparty, both the Guide and the MSFTA allow us to terminate all outstanding transactions under the applicable agreement and offset all outstanding amounts related to the terminated transactions including collateral posted or received. Under the Guide, upon a lender event of default, we generally may offset any amounts owed to a lender against any amounts a lender may owe us under any other existing agreement, regardless of whether or not such other agreements are in default or payments are immediately due.

The terms of our contracts for securities purchased under agreements to resell and securities sold under agreements to repurchase are governed by Master Repurchase Agreements, which are based on the guidelines prescribed by the Securities Industry and Financial Markets Association. Master Repurchase Agreements provide that all transactions under the agreement constitute a single contractual relationship. An event of default by the counterparty allows the early termination of all outstanding transactions under the same agreement and we may offset all outstanding amounts related to the terminated transactions including collateral posted or received.

We also have securities purchased under agreements to resell which we transact through the Fixed Income Clearing Corporation (“FICC”). Under the rules of the FICC, all agreements for securities purchased under agreements to resell that are submitted to the FICC for clearing become transactions with the FICC that are subject to FICC clearing rules. In the event of a FICC default, all open positions at the FICC are closed and a net position is calculated.

Fair Value Disclosures [Abstract]

Fair Value

Fair Value

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.

⁽¹⁾  Derivative contracts are reported on a gross basis by level. The netting adjustment represents the effect of the legal right to offset under legally enforceable master netting arrangements to settle with the same counterparty on a net basis, including cash collateral posted and received.

The following tables display a reconciliation of all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3). The tables also display gains and losses due to changes in fair value, including both realized and unrealized gains and losses, recognized in our condensed consolidated statements of operations and comprehensive income for Level 3 assets and liabilities. When assets and liabilities are transferred between levels, we recognize the transfer as of the end of the period.

⁽¹⁾  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⁾  Default rate as disclosed represents the estimated beginning annualized rate of default and is used as a basis to forecast the future default rates that serve as an input for valuation.

⁽³⁾  Includes Fannie Mae and Freddie Mac securities.

⁽⁴⁾  Includes instruments for which the prepayment speed as disclosed represents the estimated annualized rate of prepayment after all prepayment penalty provisions have expired and also instruments for which prepayment speed as disclosed represents the estimated rate of prepayment over the remaining life of the instrument.

In our condensed consolidated balance sheets certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when we evaluate loans for impairment). We did not have any Level 1 assets or liabilities held as of September 30, 2016 or December 31, 2015 that were measured at fair value on a nonrecurring basis. We held $475 million and $17 million in Level 2 assets, comprised of mortgage loans held for sale, and no Level 2 liabilities that were measured at fair value on a nonrecurring basis as of September 30, 2016 and December 31, 2015, respectively.

The following table displays valuation techniques for our Level 3 assets measured at fair value on a nonrecurring basis. 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 in more specific situations.

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.

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 in active markets 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.

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.

Dealer Mark: This valuation technique utilizes one dealer 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.

For 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: We derive the fair value of mortgage loans primarily using a build-up valuation technique. In the build-up valuation technique we start with the base value for our Fannie Mae MBS and then add or subtract the fair value of the associated guaranty asset, guaranty obligation (“GO”) and master servicing arrangement. We use observable market values of Fannie Mae MBS with similar characteristics, either on a pool or loan level, 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. 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 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 also estimate the fair value of the GO using our current guaranty pricing and adjust that pricing, as appropriate, for the seasoning of the collateral when such transactions reflect credit characteristics of loans held in our portfolio. As a result, the fair value of our mortgage loans will change when the pricing for our credit guaranty changes in the GSE securitization market.

Our performing 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 and certain reperforming loans represents an estimate of the prices we would receive if we were to sell these loans in the whole-loan market. Key factors that influence the price of these loans include collateral value, estimated loan cash flows and mortgage insurance. Collateral value is derived from the current estimated mark-to-market LTV ratio of the individual loan and, where appropriate, a state-level distressed property sales discount. Cash flow characteristics include attributes such as the weighted average coupon rate and loan payment history. 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. Fair value is estimated from the extrapolation of indicative sample bids obtained from multiple active market participants plus the estimated value of any applicable mortgage insurance. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

We estimate the fair value for a portion of our senior-subordinated trust structures using the average of two or more vendor prices at the security level as a proxy for estimating loan fair value. 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 our reverse mortgages using the single vendor valuation technique. These loans are classified as Level 3 of the valuation hierarchy because significant inputs are unobservable.

Internal Model: For loans whose value it has been determined should be based on collateral value, we use an internal proprietary distressed home price model. The internal model used in this process takes one of two approaches when valuing the collateral.

The first approach relies on comparable foreclosed property sales to estimate the value of the target collateral. The comparable foreclosed property sales approach uses various factors such as geographic distance, transaction time and the value difference. The second approach referred to as the median Metropolitan Statistical Area (“MSA”) is based on the median of all the foreclosure sales of REOs in a specific MSA. Using this sales price, MSA level discount is computed and applied to the estimated non distressed value to derive an estimated fair value. If there are not enough REO sales in a specific MSA, a median state level foreclosure discount is used to estimate the fair value.

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 median MSA is based on historical accuracy. 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. 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 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 DSCR. 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 next highest priority valuation methodology available, 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 changes in market conditions. 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 third-party valuations (both current and walk forward). Based on the number of properties measured as of September 30, 2016, these methodologies comprised approximately 74% of our valuations, while accepted offers comprised approximately 20% of our valuations. Based on the number of properties measured as of December 31, 2015, these methodologies comprised approximately 77% of our valuations, while accepted offers comprised approximately 18% 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 significant 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.

We review the appraisals and broker price opinions received to determine if they have been performed in accordance with applicable standards and if the results are consistent with our observed transactions on similar properties. We make necessary adjustments as required.

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 Fannie Mae debt instruments and debt of consolidated trusts with embedded derivatives, which are recorded in our condensed consolidated balance sheets at fair value on a recurring basis.

We classify debt instruments that have quoted market prices in active markets for similar liabilities when traded as assets as Level 2 of the valuation hierarchy. For all valuation techniques used for debts instruments where there is limited activity or less transparency around these inputs to the valuation, these debt instruments are classified as Level 3 of the valuation hierarchy.

A description of our debt valuation techniques is as follows:

Consensus: We estimate the fair value of debt of Fannie Mae and our debt of consolidated trusts using an average of two or more vendor prices or dealer marks that represents estimated fair value for similar liabilities when traded as assets. 

Single Vendor: We estimate the fair value of debt of Fannie Mae and our debt of consolidated trusts using a single vendor price that represents estimated fair value for these liabilities when traded as assets.

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 the debt of Fannie Mae and our debt of consolidated trusts using a discounted cash flow technique that uses spreads based on market assumptions where available.

The valuation methodology and inputs used in estimating the fair value of MBS assets are described under “Trading Securities and Available-for-Sale Securities.” 

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 and Valuation Group, along with the Credit Valuation team, are responsible for the estimation and verification of the fair value for the majority of our financial assets and financial liabilities. These groups also provide updates to the Finance Committee on relevant market information, pricing trends, significant valuation challenges and the resolution of those challenges. The Pricing and Valuation Group, along with the Credit Valuation team, reside within our Finance Division and are independent of any trading or market related activities. Fair value measurements for acquired property and collateral dependent loans are determined by other valuation groups in the Finance Division.

Our Finance Committee includes senior representation from our Capital Markets segment, our Enterprise Risk Management and our Finance Division, and is responsible for reviewing and approving the methods used in valuing financial instruments for the purpose of financial reporting. The composition of the Finance Committee is set forth in its charter, which was approved by the Chief Executive Officer. Based on its review of valuation methodologies and fair value results for various financial instruments used for financial reporting, the Finance Committee has the ultimate responsibility over all valuation processes and results.

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 and Valuation Group performs various review and validation procedures prior to utilizing these prices in our fair value estimation process. We validate 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 vendors 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 levels of liquidity in the marketplace. If we determine that a price provided to us is outside established parameters or in certain other circumstances, 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 Real Estate Property Valuation Group utilizes third-party appraisals and broker price opinions along with internal models and market data to compare the values received on a property and determine the valuation risk based on several factors including the deviation between the various values. The property valuation team reviews the valuations with higher valuation risk for reasonableness. The internal models utilized in the process are subject to oversight from the Model Risk Management Group, which is responsible for establishing risk management controls and for reviewing models used in the determination of fair value measurements for financial reporting. In addition, our Quality Control Group reviews the 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.

For fair value reporting purposes, we mark each property in inventory each month, incorporating the values assigned by the property valuation team along with other information including accepted offers and predictions from our proprietary distressed home price model.

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 Finance Committee.

Our Real Estate Property Valuation Group reviews appraisals and broker price opinions to determine the most appropriate value by comparing data within these products with current comparable properties and market data. We conduct regular performance reviews of the counterparties that provide products and services for this process. In addition, valuation results and trend analyses are reviewed regularly by management responsible for valuing and disposing of real estate.

Fair Value of Financial Instruments

The following table displays the carrying value and estimated fair value of our financial instruments. The fair value of financial instruments we disclose includes commitments to purchase multifamily and single-family mortgage loans 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 all non-financial instruments; therefore, 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.

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 collateral that is easily traded. If we were 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.” 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.

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 similar 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.

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. If we were 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 inputs.

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 as Level 3. 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 also classified as Level 3.

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. Therefore, we take a further discount of the present value for these liquidity considerations. This discount is based on market quotes from third-party pricing services.

The fair value of the guaranty assets includes the fair value of any associated buy-ups.

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 as Level 3. The valuation methodology and inputs used in estimating the fair value of the guaranty obligations are described under “Fair Value Measurement—Mortgage Loans Held for Investment—Build-up.”

Fair Value Option

We elected the fair value option for our credit risk sharing debt securities issued under our CAS series issued prior to January 1, 2016 and certain loans that 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 such instruments.

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 “Interest income—Mortgage loans” and interest expense for the debt instruments is recorded in “Interest expense—Long-term debt” 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
		September 30, 2016									December 31, 2015

Unpaid principal balance		12,173			9,924			31,633			13,661			11,263			21,604

__________

⁽¹⁾  Includes nonaccrual loans with a fair value of $159 million and $238 million as of September 30, 2016 and December 31, 2015, respectively. The difference between unpaid principal balance and the fair value of these nonaccrual loans as of September 30, 2016 and December 31, 2015 was $32 million and $59 million, respectively. Includes loans that are 90 days or more past due with a fair value of $156 million and $256 million as of September 30, 2016 and December 31, 2015, respectively. The difference between unpaid principal balance and the fair value of these 90 or more days past due loans as of September 30, 2016 and December 31, 2015 was $26 million and $52 million, 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.

Fair value gains (losses), net	$	438		$	(1,121	)		$	(683	)	$	45			$	3			$	48

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 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 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 credit risk.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

We are party to various types of legal actions and proceedings, including actions brought on behalf of various classes of claimants. We also are subject to regulatory examinations, inquiries and investigations, and other information gathering requests. In some of the matters, indeterminate amounts are sought. Modern pleading practice in the U.S. permits considerable variation in the assertion of monetary damages or other relief. Jurisdictions may permit claimants not to specify the monetary damages sought or may permit claimants to state only that the amount sought is sufficient to invoke the jurisdiction of the trial court. This variability in pleadings, together with our and our counsel’s actual experience in litigating or settling claims, leads us to conclude that the monetary relief that may be sought by plaintiffs bears little relevance to the merits or disposition value of claims.

On a quarterly basis, we review relevant information about all pending legal actions and proceedings for the purpose of evaluating and revising our contingencies, accruals and disclosures.

We have substantial and valid defenses to the claims in the proceedings described below and intend to defend these matters vigorously. However, legal actions and proceedings of all types are subject to many uncertain factors that generally cannot be predicted with assurance. Accordingly, the outcome of any given matter and the amount or range of potential loss at particular points in time is frequently difficult to ascertain. Uncertainties can include how fact finders will evaluate documentary evidence and the credibility and effectiveness of witness testimony, and how courts will apply the law. Disposition valuations are also subject to the uncertainty of how opposing parties and their counsel may view the evidence and applicable law.

We establish an accrual for matters when a loss is probable and we can reasonably estimate the amount of such loss. For legal actions or proceedings where there is only a reasonable possibility that a loss may be incurred, or where we are not currently able to estimate the reasonably possible loss or range of loss, we do not establish an accrual. We are often unable to estimate the possible losses or ranges of losses, particularly for proceedings that are in their early stages of development, where plaintiffs seek indeterminate or unspecified damages, where there may be novel or unsettled legal questions relevant to the proceedings, or where settlement negotiations have not occurred or progressed.

Given the uncertainties involved in any action or proceeding, regardless of whether we have established an accrual, the ultimate resolution of certain of these matters may be material to our operating results for a particular period, depending on, among other factors, the size of the loss or liability imposed and the level of our net income or loss for that period.

In addition to the matters specifically described below, we are involved in a number of legal and regulatory proceedings that arise in the ordinary course of business that we do not expect will have a material impact on our business or financial condition. We have also advanced fees and expenses of certain current and former officers and directors in connection with various legal proceedings pursuant to our bylaws and indemnification agreements.

A number of putative class action lawsuits were filed in the U.S. District Court for the District of Columbia against us, FHFA as our conservator, Treasury and Freddie Mac from July through September 2013 by shareholders of Fannie Mae and/or Freddie Mac challenging the August 2012 amendment to each company’s senior preferred stock purchase agreement with Treasury. These lawsuits were consolidated and, on December 3, 2013, plaintiffs (preferred and common shareholders of Fannie Mae and/or Freddie Mac) filed a consolidated class action complaint in the U.S. District Court for the District of Columbia against us, FHFA as our conservator, Treasury and Freddie Mac (“In re Fannie Mae/Freddie Mac Senior Preferred Stock Purchase Agreement Class Action Litigations”). The preferred shareholder plaintiffs allege that the net worth sweep dividend provisions of the senior preferred stock that were implemented pursuant to the August 2012 amendments to the senior preferred stock purchase agreements nullified certain of the shareholders’ rights, particularly the right to receive dividends. The common shareholder plaintiffs allege that the August 2012 amendments constituted a taking of their property by requiring that all future profits of Fannie Mae and Freddie Mac be paid to Treasury. Plaintiffs allege claims for breach of contract and breach of the implied covenant of good faith and fair dealing against us, FHFA and Freddie Mac, a takings claim against FHFA and Treasury, and a breach of fiduciary duty claim derivatively on our and Freddie Mac’s behalf against FHFA and Treasury. Plaintiffs seek to represent several classes of preferred and/or common shareholders of Fannie Mae and/or Freddie Mac who held stock as of the public announcement of the August 2012 amendments. Plaintiffs seek unspecified damages, equitable and injunctive relief, and costs and expenses, including attorneys’ fees.

A non-class action suit, Arrowood Indemnity Company v. Fannie Mae, was filed in the U.S. District Court for the District of Columbia on September 20, 2013 by preferred shareholders against us, FHFA as our conservator, the Director of FHFA (in his official capacity), Treasury, the Secretary of the Treasury (in his official capacity) and Freddie Mac. Plaintiffs bring claims for breach of contract and breach of the implied covenant of good faith and fair dealing against us, FHFA and Freddie Mac, and claims for violation of the Administrative Procedure Act against the FHFA and Treasury defendants, alleging that the net worth sweep dividend provisions nullified certain rights of the preferred shareholders, particularly the right to receive dividends. Plaintiffs seek damages, equitable and injunctive relief, and costs and expenses, including attorneys’ fees.

On September 30, 2014, the court dismissed both lawsuits and plaintiffs in both suits filed timely notices of appeal. On October 27, 2014, the U.S. Court of Appeals for the D.C. Circuit consolidated these appeals with appeals in two other cases involving the same subject matter, but to which we are not a party. The D.C. Circuit heard oral argument on these appeals onApril 15, 2016.

On June 26, 2016, shareholder David J. Voacolo filed a lawsuit, Voacolo v. Fannie Mae, in the U.S. District Court for the District of Columbia against Fannie Mae, FHFA and Treasury alleging a violation of the Administrative Procedure Act. Plaintiff seeks damages and a holding that the August 2012 amendment to the senior preferred stock purchase agreement was arbitrary, capricious or not otherwise in accordance with the law. The defendants filed motions to dismiss on September 20, 2016.

Given the stage of these lawsuits, the substantial and novel legal questions that remain, and our substantial defenses, we are currently unable to estimate the reasonably possible loss or range of loss arising from this litigation.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2016

Accounting Policies [Abstract]

Basis of Presentation [Policy Text Block]

Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the SEC’s instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and note disclosures required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments of a normal recurring nature considered necessary for a fair presentation have been included. The accompanying condensed consolidated financial statements include our accounts as well as the accounts of other entities in which we have a controlling financial interest. All intercompany accounts and transactions have been eliminated. To conform to our current period presentation, we have reclassified certain amounts reported in our prior periods’ condensed consolidated financial statements. Results for the nine months ended September 30, 2016 may not necessarily be indicative of the results for the year ending December 31, 2016. The unaudited interim condensed consolidated financial statements as of and for the nine months ended September 30, 2016 should be read in conjunction with our audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2015 (“2015 Form 10-K”), filed with the SEC on February 19, 2016.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

Preparing condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect our reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities as of the dates of our condensed consolidated financial statements, as well as our reported amounts of revenues and expenses during the reporting periods. Management has made significant estimates in a variety of areas including, but not limited to, valuation of certain financial instruments and other assets and liabilities and allowance for loan losses. Actual results could be different from these estimates.

On January 1, 2015, we adopted regulatory guidance issued by FHFA which prescribes, among other things, guidance on when a loan should be charged off. This change in estimate resulted in the recognition on January 1, 2015 of (1) $1.8 billion in charge-offs of held for investment loans, (2) $724 million in charge-offs of preforeclosure property taxes and insurance receivable and (3) a reduction to our allowance for loan losses and our allowance for preforeclosure property taxes and insurance receivable in amounts equal to charge-offs recognized in connection with held for investment loans and preforeclosure property taxes and insurance receivable.

For the majority of our delinquent single-family loans, we charge off the loan at the date of foreclosure or other liquidation event (such as a deed-in-lieu of foreclosure or a short sale). For a subset of delinquent single-family loans, we charge off the portion of the loans that is deemed uncollectible prior to foreclosure when the loans have been delinquent for a specified length of time and meet specified mark-to-market loan-to-value (“LTV”) ratios. We continue to enhance our data collection and analysis efforts to further refine our loss estimates as we obtain incremental information on the performance of our loans.

New Accounting Pronouncements, Policy [Policy Text Block]

New Accounting Guidance

Effective January 1, 2016, we adopted guidance regarding consolidation of legal entities such as limited partnerships, limited liability corporations and securitization structures. The impact of the adoption was not material to our condensed consolidated financial statements.

In February 2016, the Financial Accounting Standards Board (“FASB”) issued guidance on leases. The guidance clarified the definition of a lease and requires lessees to recognize on the balance sheet a right-of-use asset, representing its right to use the underlying asset for the lease term, and a corresponding lease liability for all leases with terms greater than 12 months. This guidance supersedes the existing lease guidance; however, we must continue to classify leases to determine how to recognize lease-related expense in our condensed consolidated statements of operations and comprehensive income. The new guidance is effective for us on January 1, 2019. We have evaluated this guidance and determined it will not have a material impact on our condensed consolidated financial statements.

In June 2016, FASB issued guidance that changes the impairment model for most financial assets and certain other instruments. For loans, held-to-maturity debt securities and other financial assets recorded at amortized cost, entities will be required to use a new forward-looking “expected loss” model that will replace today’s “incurred loss” model and generally will result in the earlier recognition of allowances for losses. The guidance is effective on January 1, 2020 with early adoption permitted on January 1, 2019. We will recognize the impact of the new guidance through a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements and the timing of our adoption.

In August 2016, FASB issued guidance regarding classification of certain items within the statement of cash flows in order to reduce diversity in practice with respect to cash flow classifications. The guidance is effective for us on January 1, 2018 and will be applied retrospectively for each period presented. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements.

Consolidations and Transfers of Financial Assets (Policies)

9 Months Ended

Sep. 30, 2016

Consolidations and Transfers of Financial Assets [Abstract]

Consolidations, Policy [Policy Text Block]

We have interests in various entities that are considered to be VIEs. The primary types of entities are securitization trusts guaranteed by us via lender swap and portfolio securitization transactions and mortgage-backed trusts that were not created by us, as well as housing partnerships that are established to finance the acquisition, construction, development or rehabilitation of affordable multifamily and single-family housing. These interests include investments in securities issued by VIEs, such as Fannie Mae MBS created pursuant to our securitization transactions and our guaranty to the entity. We consolidate the substantial majority of our single-class securitization trusts because our role as guarantor and master servicer provides us with the power to direct matters (primarily the servicing of mortgage loans) that impact the credit risk to which we are exposed. In contrast, we do not consolidate single-class securitization trusts when other organizations have the power to direct these activities.

Unconsolidated VIEs

We do not consolidate VIEs when we are not deemed to be the primary beneficiary. Our unconsolidated VIEs include securitization trusts and limited partnerships.

Transfers and Servicing of Financial Assets, Policy [Policy Text Block]

Transfers of Financial Assets

We issue Fannie Mae MBS through portfolio securitization transactions by transferring pools of mortgage loans or mortgage-related securities to one or more trusts or special purpose entities. We are considered to be the transferor when we transfer assets from our own retained mortgage portfolio in a portfolio securitization transaction.

Mortgage Loans (Policies)

9 Months Ended

Sep. 30, 2016

Mortgage Loans on Real Estate [Abstract]

Finance, Loan and Lease Receivables, Held-for-investment, Policy [Policy Text Block]

We define the recorded investment of HFI loans as unpaid principal balance, net of unamortized premiums and discounts, other cost basis adjustments, and accrued interest receivable.

We report the carrying value of HFI loans at the unpaid principal balance, net of unamortized premiums and discounts, other cost basis adjustments, and an allowance for loan losses.

Finance, Loan and Lease Receivables, Held-for-sale, Policy [Policy Text Block]

We report the carrying value of HFS loans at the lower of cost or fair value and record valuation changes in “Investment gains, net” in our condensed consolidated statements of operations and comprehensive income.

Nonaccrual Loans [Policy Text Block]

Nonaccrual Loans

We discontinue accruing interest on loans when we believe collectibility of principal or interest is not reasonably assured, which for a single-family loan we have determined, based on our historical experience, to be when the loan becomes two months or more past due according to its contractual terms. Interest previously accrued but not collected is reversed through interest income at the date a loan is placed on nonaccrual status. We return a non-modified single-family loan to accrual status at the point that the borrower brings the loan current. We return a modified single-family loan to accrual status at the point that the borrower successfully makes all required payments during the trial period (generally three to four months) and the modification is made permanent. We place a multifamily loan on nonaccrual status when the loan becomes three months or more past due according to its contractual terms or is deemed to be individually impaired, unless the loan is well secured such that collectibility of principal and accrued interest is reasonably assured. We return a multifamily loan to accrual status when the borrower cures the delinquency of the loan or we otherwise determine that the loan is well secured such that collectibility is reasonably assured.

Troubled Debt Restructurings [Policy Text Block]

Troubled Debt Restructurings

A modification to the contractual terms of a loan that results in granting a concession to a borrower experiencing financial difficulties is considered a TDR. In addition to formal loan modifications, we also engage in other loss mitigation activities with troubled borrowers, which include repayment plans and forbearance arrangements, both of which represent informal agreements with the borrower that do not result in the legal modification of the loan’s contractual terms. We account for these informal restructurings as a TDR if we defer more than three missed payments. We also classify loans to certain borrowers who have received bankruptcy relief as TDRs.

Allowance for Loan Losses (Policies)

9 Months Ended

Sep. 30, 2016

Receivables [Abstract]

Allowance for Loan Losses [Policy Text Block]

We maintain an allowance for loan losses for HFI loans held by Fannie Mae and loans backing Fannie Mae MBS issued from consolidated trusts. When calculating our allowance for loan losses, we consider our net recorded investment in the loan at the balance sheet date, which includes unpaid principal balance, net of amortized premiums and discounts, and other cost basis adjustments. We record charge-offs as a reduction to the allowance for loan losses when losses are confirmed through the receipt of assets in full satisfaction of a loan, such as the underlying collateral upon foreclosure or cash upon completion of a short sale. Additionally, we record charge-offs as a reduction to our allowance for loan losses when a loan is determined to be uncollectible or upon the redesignation of nonperforming loans from HFI to HFS.

We aggregate single-family HFI loans that are not individually impaired based on similar risk characteristics for purposes of estimating incurred credit losses and establishing a collective single-family loss reserve using an econometric model that derives an overall loss reserve estimate. We base our allowance methodology on historical events and trends, such as loss severity (in event of default), default rates, and recoveries from mortgage insurance contracts and other credit enhancements. In addition, management performs a review of the observable data used in its estimate to ensure it is representative of prevailing economic conditions and other events existing as of the balance sheet date.

Individually impaired single-family loans currently include those restructured in a TDR and acquired credit-impaired loans. When a loan has been restructured, we measure impairment using a cash flow analysis discounted at the loan’s original effective interest rate. However, if we expect to recover our recorded investment in an individually impaired loan through probable foreclosure of the underlying collateral, we measure impairment based on the fair value of the collateral, reduced by estimated disposal costs and adjusted for estimated proceeds from mortgage, flood, or hazard insurance and other credit enhancements.

We identify multifamily loans for evaluation for impairment through a credit risk assessment process. If we determine that a multifamily loan is individually impaired, we generally measure impairment on that loan based on the fair value of the underlying collateral less estimated costs to sell the property. We establish a collective loss reserve for all loans in our multifamily guaranty book of business that are not individually impaired using an internal model that applies loss factors to loans in similar risk categories. Our loss factors are developed based on our historical default and loss severity experience.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives, Policy [Policy Text Block]

We recognize all derivatives as either assets or liabilities in our condensed consolidated balance sheets at their fair value on a trade date basis. Fair value amounts, which are netted to the extent a legal right of offset exists and is enforceable by law at the counterparty level and are inclusive of the right or obligation associated with the cash collateral posted or received, are recorded in “Other assets” or “Other liabilities” in our condensed consolidated balance sheets. See “Note 15, Fair Value” for additional information on derivatives recorded at fair value. We present cash flows from derivatives as operating activities in our condensed consolidated statements of cash flows.

We record all derivative gains and losses, including accrued interest, in “Fair value losses, net” in our condensed consolidated statements of operations and comprehensive income.

Segment Reporting [Abstract]

Segment Reporting, Policy [Policy Text Block]

Our three reportable segments are: Single-Family, Multifamily and Capital Markets. We use these three segments to generate revenue and manage business risk, and each segment is based on the type of business activities it performs. Under our segment reporting, the sum of the results for our three business segments does not equal our condensed consolidated statements of operations and comprehensive income as we separate the activity related to our consolidated trusts from the results generated by our three segments. Our business segment financial results include directly attributable revenues and expenses. We apply accounting methods for segment reporting purposes that differ from our condensed consolidated results. Additionally, we allocate to each of our segments: (1) capital using FHFA minimum capital requirements adjusted for over- or under-capitalization; (2) indirect administrative costs; and (3) a provision for federal income taxes. In addition, we allocate intracompany guaranty fee income as a charge from the Single-Family and Multifamily segments to Capital Markets for managing the credit risk on mortgage loans held by the Capital Markets group.

Offsetting [Abstract]

Derivatives, Offsetting Policy [Policy Text Block]

Derivative instruments are recorded at fair value and securities purchased under agreements to resell or similar arrangements are recorded at amortized cost in our condensed consolidated balance sheets.

We determine our rights to offset the assets and liabilities presented above with the same counterparty, including collateral posted or received, based on the contractual arrangements entered into with our individual counterparties and various rules and regulations that would govern the insolvency of a derivative counterparty.

Fair Value (Policies)

Sep. 30, 2016

Fair Value Disclosures [Abstract]

Fair Value Measurement, Policy [Policy Text Block]

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.

Fair Value Option

We elected the fair value option for our credit risk sharing debt securities issued under our CAS series issued prior to January 1, 2016 and certain loans that 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 such instruments.

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

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies, Policy [Policy Text Block]

We establish an accrual for matters when a loss is probable and we can reasonably estimate the amount of such loss. For legal actions or proceedings where there is only a reasonable possibility that a loss may be incurred, or where we are not currently able to estimate the reasonably possible loss or range of loss, we do not establish an accrual.

On a quarterly basis, we review relevant information about all pending legal actions and proceedings for the purpose of evaluating and revising our contingencies, accruals and disclosures.

⁽¹⁾  Provision (benefit) for loan losses is included in “Benefit for credit losses” in our condensed consolidated statements of operations and comprehensive income.

⁽²⁾  While we purchase the substantial majority of loans that are four or more months delinquent from our MBS trusts, we do not exercise this option to purchase loans during a forbearance period. Charge-offs of consolidated trusts generally represent loans that remained in our consolidated trusts at the time of default.

⁽³⁾  Our charge-offs for 2015 include the initial charge-offs associated with our approach to adopting the charge-off provisions of Advisory Bulletin AB 2012-02, “Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention,” as well as charge-offs relating to a change in accounting policy for nonaccrual loans.

⁽⁴⁾  Includes transfers from trusts for delinquent loan purchases.

⁽⁵⁾  Amounts represent changes in other loss reserves which are reflected in provision (benefit) for loan losses, charge-offs, and recoveries.

Fair Value Measurements Using Significant Unobservable Inputs (Level 3) [Table Text Block]

The following tables display a reconciliation of all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3). The tables also display gains and losses due to changes in fair value, including both realized and unrealized gains and losses, recognized in our condensed consolidated statements of operations and comprehensive income for Level 3 assets and liabilities. When assets and liabilities are transferred between levels, we recognize the transfer as of the end of the period.

⁽¹⁾  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⁾  Default rate as disclosed represents the estimated beginning annualized rate of default and is used as a basis to forecast the future default rates that serve as an input for valuation.

⁽³⁾  Includes Fannie Mae and Freddie Mac securities.

⁽⁴⁾  Includes instruments for which the prepayment speed as disclosed represents the estimated annualized rate of prepayment after all prepayment penalty provisions have expired and also instruments for which prepayment speed as disclosed represents the estimated rate of prepayment over the remaining life of the instrument.

Level 3 Assets Measured on Nonrecurring Basis [Table Text Block]

The following table displays valuation techniques for our Level 3 assets measured at fair value on a nonrecurring basis. 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.

Fair Value of Financial Instruments [Table Text Block]

The following table displays the carrying value and estimated fair value of our financial instruments. The fair value of financial instruments we disclose includes commitments to purchase multifamily and single-family mortgage loans 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 all non-financial instruments; therefore, the fair value of our financial assets and liabilities does not represent the underlying fair value of our total consolidated assets and liabilities.
