FEDERAL HOME LOAN BANK OF DALLAS
NOTES TO INTERIM UNAUDITED FINANCIAL STATEMENTS

Note 1—Basis of Presentation
The accompanying interim financial statements of the Federal Home Loan Bank of Dallas (the “Bank”) are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions provided by Article 10, Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and disclosures required by generally accepted accounting principles for complete financial statements. The financial statements contain all adjustments that are, in the opinion of management, necessary for a fair statement of the Bank’s financial position, results of operations and cash flows for the interim periods presented. All such adjustments were of a normal recurring nature. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full fiscal year or any other interim period.
The Bank’s significant accounting policies and certain other disclosures are set forth in the notes to the audited financial statements for the year ended December 31, 2017. The interim financial statements presented herein should be read in conjunction with the Bank’s audited financial statements and notes thereto, which are included in the Bank’s Annual Report on Form 10-K for the year ended December 31, 2017 filed with the SEC on March 22, 2018 (the “2017 10-K”). The notes to the interim financial statements update and/or highlight significant changes to the notes included in the 2017 10-K.
The Bank is one of 11 district Federal Home Loan Banks, each individually a “FHLBank” and collectively the “FHLBanks,” and, together with the Office of Finance, a joint office of the FHLBanks, the “FHLBank System.” The Office of Finance manages the sale and servicing of the FHLBanks’ consolidated obligations. The Federal Housing Finance Agency (“Finance Agency”), an independent agency in the executive branch of the U.S. government, supervises and regulates the housing government-sponsored enterprises ("GSEs"), including the FHLBanks and the Office of Finance.
     Use of Estimates and Assumptions. The preparation of financial statements in conformity with U.S. GAAP requires management to make assumptions and estimates. These assumptions and estimates may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expenses. Significant estimates include the valuations of the Bank’s investment securities, as well as its derivative instruments and any associated hedged items. Actual results could differ from these estimates.

Note 2—Recently Issued Accounting Guidance
Revenue from Contracts with Customers. On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09 "Revenue from Contracts with Customers" ("ASU 2014-09"), which outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. In addition, ASU 2014-09 amends the existing requirements for the recognition of a gain or loss on the transfer of non-financial assets that are not in a contract with a customer. ASU 2014-09 applies to all contracts with customers except those that are within the scope of certain other standards, such as financial instruments, certain guarantees, insurance contracts, and lease contracts. The guidance in ASU 2014-09 was effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 (January 1, 2017 for the Bank). Early application was not permitted. On August 12, 2015, the FASB issued ASU 2015-14 "Deferral of Effective Date," which deferred the effective date of ASU 2014-09 by one year. Earlier application was permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Bank adopted ASU 2014-09 effective January 1, 2018. The adoption of this guidance did not have a material impact on the Bank's results of operations or financial condition.
Recognition and Measurement of Financial Assets and Financial Liabilities. On January 5, 2016, the FASB issued ASU 2016-01 "Recognition and Measurement of Financial Assets and Financial Liabilities" ("ASU 2016-01"), which makes targeted improvements to existing U.S. GAAP by: (i) requiring certain equity investments to be measured at fair value with changes in fair value recognized in earnings, (ii) simplifying the impairment assessment of equity investments without readily determinable fair values, (iii) requiring public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (iv) requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the statement of condition or in the accompanying notes to the financial statements, (v) eliminating the requirement to disclose the fair value of financial instruments measured at amortized cost for organizations that are not public business entities, (vi) eliminating the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the statement of condition, (vii) requiring a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk (also referred to as “own credit”) when the organization has

7


elected to measure the liability at fair value in accordance with the fair value option for financial instruments, and (viii) clarifying that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity's other deferred tax assets. For public business entities, the guidance in ASU 2016-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption was permitted for certain provisions. The Bank adopted ASU 2016-01 effective January 1, 2018. In conjunction with the adoption of ASU 2016-01, the Bank reclassified $12,082,000 of marketable equity securities (which consist solely of mutual fund investments associated with the Bank's non-qualified deferred compensation plans) from trading securities to other assets on January 1, 2018. Other than this reclassification, the adoption of ASU 2016-01 did not have any impact on the Bank's results of operations or financial condition.
Classification of Certain Cash Receipts and Cash Payments. On August 26, 2016, the FASB issued ASU 2016-15, "Classification of Certain Cash Receipts and Cash Payments" ("ASU 2016-15"), which clarifies the guidance for classifying certain cash receipts and cash payments in the statement of cash flows. The guidance is intended to reduce existing diversity in practice regarding eight specific cash flow presentation issues. For public business entities, the guidance in ASU 2016-15 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption, including adoption in an interim period, is permitted. The guidance is to be applied using a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, the amendments for those issues would be applied as if the change was made prospectively as of the earliest date practicable. The Bank adopted ASU 2016-15 on January 1, 2018. The adoption of this guidance did not have any impact on the Bank's statement of cash flows, nor did it have any impact on the Bank's results of operations or financial condition.
Restricted Cash. On November 17, 2016, the FASB issued ASU 2016-18, "Restricted Cash" ("ASU 2016-18"), which clarifies the guidance for classifying and presenting certain cash transfers, cash receipts and cash payments in the statement of cash flows. The guidance is intended to reduce existing diversity in practice regarding restricted cash and restricted cash equivalents. For public business entities, the guidance in ASU 2016-18 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption, including adoption in an interim period, is permitted. The guidance is to be applied using a retrospective transition method to each period presented. The adoption of ASU 2016-18 on January 1, 2018 did not have any impact on the Bank's statement of cash flows, nor did it have any impact on the Bank's results of operations or financial condition.
Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. On March 10, 2017, the FASB issued ASU 2017-07 "Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" ("ASU 2017-07"). ASU 2017-07 requires an employer to disaggregate the service cost component from the other components of net periodic pension cost and net periodic postretirement benefit cost (net benefit cost). ASU 2017-07 requires an employer to report the service cost component in the same income statement line item as other compensation costs. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component. Further, ASU 2017-07 allows only the service cost component of net benefit cost to be eligible for capitalization. For public business entities, the guidance in ASU 2017-07 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The amendments in ASU 2017-07 are to be applied retrospectively for the presentation of the service cost component and the other components of net benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net benefit cost in assets. Subsequent to the adoption of ASU 2017-07 on January 1, 2018, the Bank continues to report the service cost component of its net periodic postretirement benefit cost in compensation and benefits expense. On and after January 1, 2018, the Bank reports the other components of net periodic postretirement benefit cost (which in aggregate were credits of $17,000 and $33,000 for the three and six months ended June 30, 2018, respectively) in "other, net" in the other income (loss) section of the statement of income. Because the components of the Bank's net periodic postretirement benefit cost other than the service cost component were insignificant for the six months ended June 30, 2017 (see Note 14), such amounts were not reclassified and are reported in compensation and benefits expense for that period. The adoption of ASU 2017-07 did not have any impact on the Bank's financial condition.

At June 30, 2018, the gross unrealized losses on the Bank’s available-for-sale securities were $12,497,000. All of the Bank's available-for-sale securities are either guaranteed by the U.S. government, issued by GSEs, or fully secured by collateral that is guaranteed by the U.S government. As of June 30, 2018, the U.S. government and the issuers of the Bank’s holdings of GSE debentures and GSE MBS were rated triple-A by Moody’s Investors Service (“Moody’s”) and Fitch Ratings, Ltd. (“Fitch”) and AA+ by S&P Global Ratings (“S&P”). The Bank's holdings of PEFCO debentures are rated triple-A by Moody's and Fitch, and are not rated by S&P. Based upon the Bank's assessment of the creditworthiness of the issuer of the GSE debentures that were in an unrealized loss position at June 30, 2018 and the credit ratings assigned by each of the nationally recognized statistical rating organizations (“NRSROs”), the Bank expects that these debentures would not be settled at an amount less than the Bank's amortized cost bases in the investments. In addition, based upon the Bank's assessment of the strength of the GSEs' guarantees of the Bank's holdings of GSE commercial MBS and the credit ratings assigned by each of the NRSROs, the Bank expects that its holdings of GSE commercial MBS that were in an unrealized loss position at June 30, 2018 would not be settled at an amount less than the Bank’s amortized cost bases in these investments. Because the current market value deficits associated with the Bank's available-for-sale securities are not attributable to credit quality, and because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their amortized cost bases, the Bank does not consider any of these investments to be other-than-temporarily impaired at June 30, 2018.
Redemption Terms. The amortized cost and estimated fair value of available-for-sale securities by contractual maturity at June 30, 2018 and December 31, 2017 are presented below (in thousands).

Proceeds from the sales totaled $81,005,000 and $250,262,000, respectively, resulting in realized gains of $1,167,000 and $1,837,000, respectively.

At June 30, 2018, the gross unrealized losses on the Bank’s held-to-maturity securities were $2,965,000, of which $1,127,000 were attributable to its holdings of non-agency (i.e., private-label) residential MBS, $750,000 were attributable to securities that are either guaranteed by the U.S. government or issued and guaranteed by GSEs and $1,088,000 were attributable to a security issued by a state housing agency.
As of June 30, 2018, the U.S. government and the issuers of the Bank’s holdings of GSE MBS were rated triple-A by Moody’s and Fitch and AA+ by S&P. Based upon the Bank's assessment of the strength of the government guaranty, the Bank expects that the U.S. government-guaranteed obligation that was in an unrealized loss position at June 30, 2018 would not be settled at an amount less than the Bank's amortized cost basis in this investment. In addition, based upon the credit ratings assigned by the NRSROs and the Bank's assessment of the strength of the GSEs’ guarantees of the Bank’s holdings of GSE MBS, the Bank expects that its holdings of GSE MBS that were in an unrealized loss position at June 30, 2018 would not be settled at an amount less than the Bank’s amortized cost bases in these investments. Finally, based upon the Bank's assessment of the creditworthiness of the state housing agency and the triple-A credit ratings assigned by the NRSROs, the Bank expects that the state housing agency debenture that was in an unrealized loss position at June 30, 2018 would not be settled at an amount less than the Bank’s amortized cost basis in this investment. Because the current market value deficits associated with these securities are not attributable to credit quality, and because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their amortized cost bases, the Bank does not consider any of these investments to be other-than-temporarily impaired at June 30, 2018.

The deterioration in the U.S. housing markets that occurred primarily during the period from 2007 through 2011, as reflected during that period by declines in the values of residential real estate and higher levels of delinquencies, defaults and losses on residential mortgages, including the mortgages underlying the Bank’s non-agency residential MBS (“RMBS”), generally increased the risk that the Bank may not ultimately recover the entire cost bases of some of its non-agency RMBS. However, based upon its analysis of the securities in this portfolio, the Bank believes that the unrealized losses as of June 30, 2018 were principally the result of liquidity risk related discounts in the non-agency RMBS market and do not accurately reflect the currently likely future credit performance of the securities.
Because the ultimate receipt of contractual payments on the Bank’s non-agency RMBS will depend upon the credit and prepayment performance of the underlying loans and the credit enhancements for the senior securities owned by the Bank, the Bank closely monitors these investments in an effort to determine whether the credit enhancement associated with each security is sufficient to protect against potential losses of principal and interest on the underlying mortgage loans. The credit enhancement for each of the Bank’s non-agency RMBS is provided by a senior/subordinate structure, and none of the securities owned by the Bank are insured by third-party bond insurers. More specifically, each of the Bank’s non-agency RMBS represents a single security class within a securitization that has multiple classes of securities. Each security class has a distinct claim on the cash flows from the underlying mortgage loans, with the subordinate securities having a junior claim relative to the more senior securities. The Bank’s non-agency RMBS have a senior claim on the cash flows from the underlying mortgage loans.
To assess whether the entire amortized cost bases of its 23 non-agency RMBS holdings are likely to be recovered, the Bank performed a cash flow analysis for each security as of June 30, 2018 using two third-party models. The first model considers borrower characteristics and the particular attributes of the loans underlying the Bank’s securities, in conjunction with assumptions about future changes in home prices and interest rates, to project prepayments, defaults and loss severities. A significant input to the first model is the forecast of future housing price changes for the relevant states and core based statistical areas (“CBSAs”), which are based upon an assessment of the individual housing markets. (The term “CBSA” refers collectively to metropolitan and micropolitan statistical areas as defined by the U.S. Office of Management and Budget; as currently defined, a CBSA must contain at least one urban area of 10,000 or more people.) The Bank’s housing price forecast as of June 30, 2018 assumed changes in home prices ranging from declines of 8 percent to increases of 13 percent over the 12-month period beginning April 1, 2018. For the vast majority of markets, the changes were projected to range from increases of 2 percent to 7 percent. Thereafter, home price changes for each market were projected to return (at varying rates and over varying transition periods based on historical housing price patterns) to their long-term historical equilibrium levels. Following these transition periods, the constant long-term annual rates of appreciation for the vast majority of markets were projected to range between 2 percent and 5 percent.
The month-by-month projections of future loan performance derived from the first model, which reflect projected prepayments, defaults and loss severities, are then input into a second model that allocates the projected loan level cash flows and losses to the various security classes in the securitization structure in accordance with its prescribed cash flow and loss allocation rules. In a securitization in which the credit enhancement for the senior securities is derived from the presence of subordinate securities, losses are generally allocated first to the subordinate securities until their principal balance is reduced to zero.
Based on the results of its cash flow analyses, the Bank determined it is likely that it will fully recover the remaining amortized cost bases of all of its non-agency RMBS. Because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their remaining amortized cost bases, none of the Bank's non-agency RMBS were deemed to be other-than-temporarily impaired at June 30, 2018.
During the year ended December 31, 2016, one of the Bank's non-agency RMBS was determined to be other-than-temporarily impaired. In addition, 14 of the Bank's non-agency RMBS were determined to be other-than-temporarily impaired in periods prior to 2013.
