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, what form we will have, 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 in 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, 2015. 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, 2015. As of September 30, 2015, 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 $4.4 billion on September 30, 2015 based on our net worth of $6.2 billion as of June 30, 2015 less the applicable capital reserve of $1.8 billion. We expect to pay Treasury an additional dividend of $2.2 billion by December 31, 2015 based on our net worth of $4.0 billion as of September 30, 2015 less the applicable capital reserve amount of $1.8 billion. The capital reserve amount was $2.4 billion for dividend periods in 2014. 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, 2015 may not necessarily be indicative of the results for the year ending December 31, 2015. The unaudited interim condensed consolidated financial statements as of and for the nine months ended September 30, 2015 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, 2014 (“2014 Form 10-K”), filed with the SEC on February 20, 2015. Changes in Accounting Principle—Nonaccrual Loans Effective January 1, 2015, we changed our policy for the treatment of interest previously accrued but not collected at the date both single-family and multifamily loans are placed on nonaccrual status. Specifically, interest previously accrued but not collected will be reversed through interest income at the date a loan is placed on nonaccrual status. Previously, when a loan was placed on nonaccrual status, interest previously accrued but not collected became part of each loan’s recorded investment and was reviewed either individually or collectively for impairment. We also changed our policy for when a non-modified single-family loan is returned to accrual status. Effective January 1, 2015, a non-modified single-family loan will be returned to accrual status at the point that the borrower brings the loan current. Previously, a non-modified single-family loan was returned to accrual status at the point that the borrower had made sufficient payments to reduce the delinquency status below our nonaccrual threshold of 60 days past due. We have concluded that these changes in accounting principle are preferable as we align our nonaccrual policy with industry practice. This alignment increases comparability of our financial statements to these entities, resulting in improved financial reporting. As these changes to our nonaccrual policy were not material to our financial statements, we wrote off the accrued interest receivable balance on our nonaccrual loans, as well as the corresponding allowance that related to that interest, as an adjustment to the 2015 provision for loan losses and did not retrospectively adjust the condensed consolidated financial statements for this change. Change in Accounting Principle—Loans Held for Sale Effective January 1, 2015, we changed our policy for calculating the lower of cost or fair value adjustment on loans that have been designated as held for sale (“HFS”). Specifically, our lower of cost or fair value calculation will be performed at an individual loan level on the date of redesignation, if previously held for investment (“HFI”), and for all subsequent periods in which a loan is classified as HFS. Previously, the initial lower of cost or fair value adjustment on the date of re-designation was calculated at a loan level whereas the subsequent lower of cost or fair value adjustments were calculated at a pool level. We have concluded that this change in accounting policy is preferable as it will align the unit of account that is used for both the initial and subsequent lower of cost or market measurements on our HFS portfolio. Additionally, by performing the lower of cost or fair value calculation at the loan level, the adjustment will be calculated on a more disaggregated basis. As this change in accounting policy is not material to our financial statements, we recorded the impact of this change in accounting principle as an adjustment to 2015 fair value losses, net and did not retrospectively adjust the condensed consolidated financial statements for this change. Regulatory Capital FHFA has announced that, during the conservatorship, our existing statutory and FHFA-directed regulatory capital requirements will not be binding and that 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 $140.6 billion as of September 30, 2015 and $142.2 billion as of December 31, 2014. 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 directs 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, 2015, Treasury held an investment in our senior preferred stock with an aggregate liquidation preference of $117.1 billion. FHFA’s control of Fannie Mae and Freddie Mac has caused us, FHFA and Freddie Mac to be deemed related parties. Our administrative expenses were reduced by $18 million for the three months ended September 30, 2015 and 2014 and $50 million and $55 million for the nine months ended September 30, 2015 and 2014, 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, 2015, we made tax payments of $100 million and $470 million, respectively, to the Internal Revenue Service (“IRS”), a bureau of Treasury. We did not make any tax payments during the three months ended September 30, 2014. We made tax payments of $2.5 billion during the nine months ended September 30, 2014. 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. Under the temporary credit and liquidity facilities (“TCLF”) program, we had no outstanding standby credit and liquidity support as of September 30, 2015. We had $390 million outstanding, which includes principal and interest, of standby credit and liquidity support as of December 31, 2014. Under the new issue bond (“NIB”) program, we had $3.9 billion and $4.2 billion outstanding of pass-through securities backed by single-family and multifamily housing bonds issued by housing finance agencies (“HFAs”) as of September 30, 2015 and December 31, 2014, respectively. Treasury will bear the initial losses of principal under the TCLF program and the NIB program up to 35% of the total original principal on a combined program-wide basis, and thereafter we will bear the losses of principal that are attributable to the TCLF and the securities we have issued. Treasury will also bear any losses of unpaid interest under the two programs. As of September 30, 2015, there had been no losses of principal or interest under the TCLF program or 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 $413 million and $351 million in TCCA fees during the three months ended September 30, 2015 and 2014, respectively, and $1.2 billion and $1.0 billion for the nine months ended September 30, 2015 and 2014, respectively, of which $413 million had not been remitted to Treasury as of September 30, 2015. For the three and nine months ended September 30, 2015, we accrued, but have not yet paid, $56 million and $168 million, respectively, in expenses in connection with certain funding obligations under the GSE Act, a portion of which is attributable to Treasury’s Capital Magnet Fund. 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 total new business purchases for the three and nine months ended September 30, 2015. As of September 30, 2015 and December 31, 2014, we held Freddie Mac mortgage-related securities with a fair value of $6.1 billion and $6.9 billion, respectively. We recognized interest income on these securities held by us of $55 million and $68 million for the three months ended September 30, 2015 and 2014, respectively, and $174 million and $219 million for the nine months ended September 30, 2015 and 2014, respectively. In addition, Freddie Mac may be an investor in variable interest entities that we have consolidated, and we may be an investor in variable interest entities that Freddie Mac has consolidated. 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 and $26 million for the three months ended September 30, 2015 and 2014, respectively, and $84 million and $80 million for the nine months ended September 30, 2015 and 2014, respectively. Fannie Mae and Freddie Mac established Common Securitization Solutions, LLC (“CSS”), a jointly owned limited liability company, to operate a common securitization platform. During the three and nine months ended September 30, 2015, we contributed $17 million and $47 million, respectively, of capital into CSS, and we made no contributions for the three and nine months ended September 30, 2014. No other transactions outside of normal business activities have occurred between us and Freddie Mac during the nine months ended September 30, 2015 or 2014. 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, recoverability of our deferred tax assets and allowance for loan losses. Actual results could be different from these estimates. In April 2012, FHFA issued 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”), which prescribes, among other things, classification of loans by risk category and provides guidance on when a loan should be charged off. The provisions of the Advisory Bulletin led us to re-evaluate our estimate of when a loan is deemed uncollectible. For the vast majority of our delinquent single-family loans, we will continue to 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 relatively small subset of delinquent loans deemed to be uncollectible prior to foreclosure based upon our historical data, we charge off the portion of the loan (including preforeclosure property taxes and insurance receivable that pertain to such loans) deemed to be uncollectible prior to the date of foreclosure or other liquidation event, which given our current credit analytics and historical data, is when the loans are excessively delinquent and the outstanding loan balance exceeds the fair value of the underlying property. This change in estimate resulted in the recognition on January 1, 2015 of (1) $1.8 billion in charge-offs of HFI 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 HFI loans and preforeclosure property taxes and insurance receivable. 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. Fee and Other Income Fee and other income includes transaction fees, multifamily fees, technology fees and other miscellaneous income. During the three and nine months ended September 30, 2014, we recognized $538 million and $4.8 billion, respectively, in “Fee and other income” in our condensed consolidated statement of operations and comprehensive income resulting from settlement agreements resolving certain lawsuits relating to private-label mortgage-related securities (“PLS”) sold to us. There were no settlement agreements resolving PLS lawsuits during the three and nine months ended September 30, 2015. Employee Retirement Benefits In 2013, our defined benefit pension plans were amended to cease the accrual of benefits for all employees and the plans were subsequently terminated, effective December 31, 2013. The additional cost of the termination, including the estimated premium required to purchase annuity contracts, was recognized in “Other comprehensive income” in our condensed consolidated statement of operations and comprehensive income for the year ended December 31, 2013. During the three months ended September 30, 2015, we settled our defined pension benefit obligations. We transferred plan assets to an annuity provider and distributed lump sum payments to participants based on their elections. We made a cash contribution of $102 million to settle the plans. 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. New Accounting Guidance Effective January 1, 2015, we prospectively adopted guidance issued by the Financial Accounting Standards Board (“FASB”) clarifying when a creditor is considered to have received physical possession of residential real estate property collateralized by a consumer mortgage loan. The adoption of this guidance resulted in a clarification to our policy to align our definition of when we have taken physical possession of real estate with the new guidance; however it did not impact the timing of derecognition of loan receivable and recognition of real estate property in our financial statements. The new guidance also requires us to disclose the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. See “Note 3, Mortgage Loans” for additional information regarding the disclosure required upon adoption of this guidance. Effective January 1, 2015, we prospectively adopted guidance issued by the FASB related to the classification of government guaranteed mortgage loans upon foreclosure. The impact of the adoption was not material to the condensed consolidated balance sheets. In February 2015, the FASB issued guidance regarding consolidation of legal entities such as limited partnerships, limited liability corporations and securitization structures. The guidance removes the specialized consolidation model surrounding limited partnerships and similar entities and amends the requirements that such entities must meet to qualify as voting interest entities. In addition, the guidance eliminates certain of the conditions for evaluating whether fees paid to a decision maker or service provider represent a variable interest. The new guidance is effective for us on January 1, 2016 with early adoption permitted. We are currently evaluating the potential impact of the new guidance on our consolidated financial statements.

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, what form we will have, 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 in 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, 2015. 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, 2015. As of September 30, 2015, 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 $4.4 billion on September 30, 2015 based on our net worth of $6.2 billion as of June 30, 2015 less the applicable capital reserve of $1.8 billion. We expect to pay Treasury an additional dividend of $2.2 billion by December 31, 2015 based on our net worth of $4.0 billion as of September 30, 2015 less the applicable capital reserve amount of $1.8 billion. The capital reserve amount was $2.4 billion for dividend periods in 2014. 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, 2015 may not necessarily be indicative of the results for the year ending December 31, 2015. The unaudited interim condensed consolidated financial statements as of and for the nine months ended September 30, 2015 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, 2014 (“2014 Form 10-K”), filed with the SEC on February 20, 2015.

Changes in Accounting Principle—Nonaccrual Loans

Effective January 1, 2015, we changed our policy for the treatment of interest previously accrued but not collected at the date both single-family and multifamily loans are placed on nonaccrual status. Specifically, interest previously accrued but not collected will be reversed through interest income at the date a loan is placed on nonaccrual status. Previously, when a loan was placed on nonaccrual status, interest previously accrued but not collected became part of each loan’s recorded investment and was reviewed either individually or collectively for impairment.

We also changed our policy for when a non-modified single-family loan is returned to accrual status. Effective January 1, 2015, a non-modified single-family loan will be returned to accrual status at the point that the borrower brings the loan current. Previously, a non-modified single-family loan was returned to accrual status at the point that the borrower had made sufficient payments to reduce the delinquency status below our nonaccrual threshold of 60 days past due.

We have concluded that these changes in accounting principle are preferable as we align our nonaccrual policy with industry practice. This alignment increases comparability of our financial statements to these entities, resulting in improved financial reporting.

As these changes to our nonaccrual policy were not material to our financial statements, we wrote off the accrued interest receivable balance on our nonaccrual loans, as well as the corresponding allowance that related to that interest, as an adjustment to the 2015 provision for loan losses and did not retrospectively adjust the condensed consolidated financial statements for this change.

Change in Accounting Principle—Loans Held for Sale

Effective January 1, 2015, we changed our policy for calculating the lower of cost or fair value adjustment on loans that have been designated as held for sale (“HFS”). Specifically, our lower of cost or fair value calculation will be performed at an individual loan level on the date of redesignation, if previously held for investment (“HFI”), and for all subsequent periods in which a loan is classified as HFS. Previously, the initial lower of cost or fair value adjustment on the date of re-designation was calculated at a loan level whereas the subsequent lower of cost or fair value adjustments were calculated at a pool level.

We have concluded that this change in accounting policy is preferable as it will align the unit of account that is used for both the initial and subsequent lower of cost or market measurements on our HFS portfolio. Additionally, by performing the lower of cost or fair value calculation at the loan level, the adjustment will be calculated on a more disaggregated basis.

As this change in accounting policy is not material to our financial statements, we recorded the impact of this change in accounting principle as an adjustment to 2015 fair value losses, net and did not retrospectively adjust the condensed consolidated financial statements for this change.

Regulatory Capital

FHFA has announced that, during the conservatorship, our existing statutory and FHFA-directed regulatory capital requirements will not be binding and that 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 $140.6 billion as of September 30, 2015 and $142.2 billion as of December 31, 2014.

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 directs 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, 2015, Treasury held an investment in our senior preferred stock with an aggregate liquidation preference of $117.1 billion. FHFA’s control of Fannie Mae and Freddie Mac has caused us, FHFA and Freddie Mac to be deemed related parties.

Our administrative expenses were reduced by $18 million for the three months ended September 30, 2015 and 2014 and $50 million and $55 million for the nine months ended September 30, 2015 and 2014, 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, 2015, we made tax payments of $100 million and $470 million, respectively, to the Internal Revenue Service (“IRS”), a bureau of Treasury. We did not make any tax payments during the three months ended September 30, 2014. We made tax payments of $2.5 billion during the nine months ended September 30, 2014. 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.

Under the temporary credit and liquidity facilities (“TCLF”) program, we had no outstanding standby credit and liquidity support as of September 30, 2015. We had $390 million outstanding, which includes principal and interest, of standby credit and liquidity support as of December 31, 2014. Under the new issue bond (“NIB”) program, we had $3.9 billion and $4.2 billion outstanding of pass-through securities backed by single-family and multifamily housing bonds issued by housing finance agencies (“HFAs”) as of September 30, 2015 and December 31, 2014, respectively. Treasury will bear the initial losses of principal under the TCLF program and the NIB program up to 35% of the total original principal on a combined program-wide basis, and thereafter we will bear the losses of principal that are attributable to the TCLF and the securities we have issued. Treasury will also bear any losses of unpaid interest under the two programs. As of September 30, 2015, there had been no losses of principal or interest under the TCLF program or 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 $413 million and $351 million in TCCA fees during the three months ended September 30, 2015 and 2014, respectively, and $1.2 billion and $1.0 billion for the nine months ended September 30, 2015 and 2014, respectively, of which $413 million had not been remitted to Treasury as of September 30, 2015.

For the three and nine months ended September 30, 2015, we accrued, but have not yet paid, $56 million and $168 million, respectively, in expenses in connection with certain funding obligations under the GSE Act, a portion of which is attributable to Treasury’s Capital Magnet Fund. 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 total new business purchases for the three and nine months ended September 30, 2015.

As of September 30, 2015 and December 31, 2014, we held Freddie Mac mortgage-related securities with a fair value of $6.1 billion and $6.9 billion, respectively. We recognized interest income on these securities held by us of $55 million and $68 million for the three months ended September 30, 2015 and 2014, respectively, and $174 million and $219 million for the nine months ended September 30, 2015 and 2014, respectively. In addition, Freddie Mac may be an investor in variable interest entities that we have consolidated, and we may be an investor in variable interest entities that Freddie Mac has consolidated.

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 and $26 million for the three months ended September 30, 2015 and 2014, respectively, and $84 million and $80 million for the nine months ended September 30, 2015 and 2014, respectively.

Fannie Mae and Freddie Mac established Common Securitization Solutions, LLC (“CSS”), a jointly owned limited liability company, to operate a common securitization platform. During the three and nine months ended September 30, 2015, we contributed $17 million and $47 million, respectively, of capital into CSS, and we made no contributions for the three and nine months ended September 30, 2014. No other transactions outside of normal business activities have occurred between us and Freddie Mac during the nine months ended September 30, 2015 or 2014.

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, recoverability of our deferred tax assets and allowance for loan losses. Actual results could be different from these estimates.

In April 2012, FHFA issued 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”), which prescribes, among other things, classification of loans by risk category and provides guidance on when a loan should be charged off. The provisions of the Advisory Bulletin led us to re-evaluate our estimate of when a loan is deemed uncollectible. For the vast majority of our delinquent single-family loans, we will continue to 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 relatively small subset of delinquent loans deemed to be uncollectible prior to foreclosure based upon our historical data, we charge off the portion of the loan (including preforeclosure property taxes and insurance receivable that pertain to such loans) deemed to be uncollectible prior to the date of foreclosure or other liquidation event, which given our current credit analytics and historical data, is when the loans are excessively delinquent and the outstanding loan balance exceeds the fair value of the underlying property. This change in estimate resulted in the recognition on January 1, 2015 of (1) $1.8 billion in charge-offs of HFI 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 HFI loans and preforeclosure property taxes and insurance receivable. 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.

Fee and Other Income

Fee and other income includes transaction fees, multifamily fees, technology fees and other miscellaneous income. During the three and nine months ended September 30, 2014, we recognized $538 million and $4.8 billion, respectively, in “Fee and other income” in our condensed consolidated statement of operations and comprehensive income resulting from settlement agreements resolving certain lawsuits relating to private-label mortgage-related securities (“PLS”) sold to us. There were no settlement agreements resolving PLS lawsuits during the three and nine months ended September 30, 2015.

Employee Retirement Benefits

In 2013, our defined benefit pension plans were amended to cease the accrual of benefits for all employees and the plans were subsequently terminated, effective December 31, 2013. The additional cost of the termination, including the estimated premium required to purchase annuity contracts, was recognized in “Other comprehensive income” in our condensed consolidated statement of operations and comprehensive income for the year ended December 31, 2013.

During the three months ended September 30, 2015, we settled our defined pension benefit obligations. We transferred plan assets to an annuity provider and distributed lump sum payments to participants based on their elections. We made a cash contribution of $102 million to settle the plans. 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.

New Accounting Guidance

Effective January 1, 2015, we prospectively adopted guidance issued by the Financial Accounting Standards Board (“FASB”) clarifying when a creditor is considered to have received physical possession of residential real estate property collateralized by a consumer mortgage loan. The adoption of this guidance resulted in a clarification to our policy to align our definition of when we have taken physical possession of real estate with the new guidance; however it did not impact the timing of derecognition of loan receivable and recognition of real estate property in our financial statements. The new guidance also requires us to disclose the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. See “Note 3, Mortgage Loans” for additional information regarding the disclosure required upon adoption of this guidance.

Effective January 1, 2015, we prospectively adopted guidance issued by the FASB related to the classification of government guaranteed mortgage loans upon foreclosure. The impact of the adoption was not material to the condensed consolidated balance sheets.

In February 2015, the FASB issued guidance regarding consolidation of legal entities such as limited partnerships, limited liability corporations and securitization structures. The guidance removes the specialized consolidation model surrounding limited partnerships and similar entities and amends the requirements that such entities must meet to qualify as voting interest entities. In addition, the guidance eliminates certain of the conditions for evaluating whether fees paid to a decision maker or service provider represent a variable interest. The new guidance is effective for us on January 1, 2016 with early adoption permitted. We are currently evaluating the potential impact of the new guidance on our consolidated financial statements.
