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, 2012. 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, 2012 filed with the SEC on March 25, 2013 (the “2012 10-K”). The notes to the interim financial statements update and/or highlight significant changes to the notes included in the 2012 10-K.

The Bank is one of 12 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 FHLBanks and the Office of Finance.

Use of Estimates. 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 assumptions include those that are used by the Bank in its periodic evaluation of its holdings of non-agency residential mortgage-backed securities for other-than-temporary impairment (“OTTI”). 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

Presentation of Comprehensive Income. On February 5, 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02"Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income"("ASU 2013-02"), which requires an entity to report, either on the face of the statement where net income is presented or in the notes, the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. The guidance in ASU 2013-02 is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2012 (January 1, 2013 for the Bank). The adoption of this guidance did not have any impact on the Bank’s results of operations or financial condition. The required disclosures are presented in Note 17.

Disclosures about Offsetting Assets and Liabilities. On December 16, 2011, the FASB issued ASU 2011-11 "Disclosures about Offsetting Assets and Liabilities," which, as clarified, requires enhanced disclosures about derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in the statement of financial position or subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset. This information is intended to enable users of an entity's financial statements to evaluate the effect or potential effect of netting arrangements on an entity's financial position, including the effect or potential effect of rights of setoff associated with these types of financial instruments.

The eligibility criteria for offsetting are different in International Financial Reporting Standards ("IFRSs") and U.S. GAAP. For example, unlike IFRSs, U.S. GAAP allows entities the option to present net in their balance sheets derivatives that are subject to a legally enforceable netting arrangement with the same party where rights of setoff are only available in the event of default or bankruptcy. The new disclosure requirements allow investors to better compare financial statements prepared in accordance with IFRSs or U.S. GAAP and improve transparency in the reporting of how entities mitigate credit risk, including disclosure of related collateral pledged or received.

6

The guidance is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods (January 1, 2013 for the Bank), and is to be applied retrospectively to all periods presented. The adoption of this guidance did not have any impact on the Bank’s results of operations or financial condition. The required disclosures are presented in Note 9.

Asset Classification and Charge-offs. On April 9, 2012, the Finance Agency issued Advisory Bulletin 2012-02, "Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention" ("AB 2012-02"). The guidance establishes a standard and uniform methodology for classifying assets and prescribes the timing of asset charge-offs, excluding investment securities. The guidance in AB 2012-02 is generally consistent with the Uniform Retail Credit Classification and Account Management Policy issued by the federal banking regulators in June 2000. The adoption of the accounting guidance in AB 2012-02, which is effective January 1, 2015, is not expected to have a significant impact on the Bank's results of operations or financial condition.

Joint and Several Liability Arrangements. On February 28, 2013, the FASB issued ASU 2013-04 “Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date” (“ASU 2013-04”), which provides guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of the guidance is fixed at the reporting date. ASU 2013-04 requires an entity to measure these obligations as the sum of (1) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (2) any additional amount the reporting entity expects to pay on behalf of its co-obligors. ASU 2013-04 also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The guidance in ASU 2013-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 (January 1, 2014 for the Bank) and is to be applied retrospectively to all prior periods presented. The adoption of this guidance will not have any impact on the Bank's financial condition or results of operations.

At June 30, 2013, the gross unrealized losses on the Bank’s available-for-sale securities were $5,571,000. All of the Bank's available-for-sale securities are either guaranteed by the U.S. government, issued by government-sponsored enterprises (“GSEs”), or fully secured by collateral that is guaranteed by the U.S government. As of June 30, 2013, the U.S. government and the issuers of the Bank’s holdings of GSE debentures were rated triple-A by Moody’s Investors Service (“Moody’s”) and Fitch Ratings, Ltd. (“Fitch”) and AA+ by Standard and Poor’s (“S&P”). The Bank's holdings of other debentures were rated Aaa by Moody's and AA+ by S&P at that date; the other debentures are not rated by Fitch. Based upon the Bank's assessment of the strength of the government guaranty, the Bank expects that the U.S. government-guaranteed debenture that was in an unrealized loss position at June 30, 2013 would not be settled at an amount less than the Bank's amortized cost basis in the investment. In addition, based upon the Bank’s assessment of the creditworthiness of the issuers of the GSE debentures and the credit ratings assigned by each of the nationally recognized statistical rating organizations (“NRSROs”), the Bank expects that its holdings of GSE debentures that were in an unrealized loss position at June 30, 2013 would not be settled at an amount less than the Bank’s amortized cost bases in these investments. Further, based on the creditworthiness of the issuer of the Bank's holdings of other debentures, the U.S. government's guaranty of the payment of principal and interest on the collateral securing those debentures, and the guaranty of the payment of interest on the debentures by an agency of the U.S. government, the Bank expects that its holdings of other debentures that were in an unrealized loss position at June 30, 2013 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, 2013.

At June 30, 2013, the gross unrealized losses on the Bank’s held-to-maturity securities were $24,330,000, of which $23,116,000 was attributable to its holdings of non-agency (i.e., private-label) residential mortgage-backed securities and $1,214,000 was attributable to securities that are either guaranteed by the U.S. government or issued and guaranteed by GSEs. As of June 30, 2013, the U.S. government and the issuers of the Bank’s holdings of GSE mortgage-backed securities ("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 guarantees of the debentures held by the Bank, the credit ratings assigned by the NRSROs and the strength of the GSEs’ guarantees of the Bank’s holdings of agency MBS, the Bank expects that its holdings of U.S. government-guaranteed debentures and GSE MBS that were in an unrealized loss position at June 30, 2013 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 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, 2013.

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. Based on its analysis of the securities in this portfolio, however, the Bank believes that the unrealized losses as of June 30, 2013 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 30 non-agency RMBS holdings are likely to be recovered, the Bank performed a cash flow analysis for each security as of June 30, 2013 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, 2013 assumed changes in home prices ranging from declines of 5 percent to increases of 7 percent over the 12-month period beginning April 1, 2013. For the vast majority of markets, the changes were projected to range from declines of 3 percent to increases of 5 percent. Thereafter, home prices were projected to recover using one of five different recovery paths that vary by housing market. Under those recovery paths, home prices were projected to increase as set forth in the table below.

11

Months	Range of Annualized Rates
1 - 6	0.0	%	-	3.0%
7 - 12	1.0	%	-	4.0%
13 - 18	2.0	%	-	4.0%
19 - 30	2.0	%	-	5.0%
31 - 54	2.0	%	-	6.0%
Thereafter	2.3	%	-	5.6%

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 these securities were deemed to be other-than-temporarily impaired as of June 30, 2013.

Prior to July 1, 2012, 14 of the Bank's holdings of non-agency RMBS were determined to be other-than-temporarily impaired. The following table sets forth additional information for each of the securities that was deemed to be other-than-temporarily impaired in a prior period (in thousands). All of the Bank’s non-agency RMBS are rated by Moody’s, S&P and/or Fitch. The credit ratings presented in the table represent the lowest rating assigned to the security by any of these NRSROs as of June 30, 2013.

The balance of overdrawn demand deposit accounts was fully collateralized at December 31, 2012 and was repaid in early January 2013. Amortizing advances require repayment according to predetermined amortization schedules.

The Bank offers advances to members that may be prepaid on specified dates without the member incurring prepayment or termination fees (prepayable and callable advances). The prepayment of other advances requires the payment of a fee to the Bank (prepayment fee) if necessary to make the Bank financially indifferent to the prepayment of the advance. At June 30, 2013 and December 31, 2012, the Bank had aggregate prepayable and callable advances totaling $114,253,000 and $121,123,000, respectively.

The following table summarizes advances outstanding at June 30, 2013 and December 31, 2012, by the earliest of contractual maturity, next call date, or the first date on which prepayable advances can be repaid without a prepayment fee (in thousands):

Contractual Maturity or Next Call Date	June 30, 2013		December 31, 2012

The Bank also offers putable advances. With a putable advance, the Bank purchases a put option from the member that allows the Bank to terminate the fixed-rate advance on specified dates and offer, subject to certain conditions, replacement funding at prevailing market rates. At June 30, 2013 and December 31, 2012, the Bank had putable advances outstanding totaling $2,305,471,000 and $2,572,471,000, respectively.

The following table summarizes advances outstanding at June 30, 2013 and December 31, 2012, by the earlier of contractual maturity or next possible put date (in thousands):

Total par value	$	18,056,016	$	17,928,256

At June 30, 2013 and December 31, 2012, 35 percent and 42 percent, respectively, of the Bank’s fixed-rate advances were swapped to a variable rate.

Prepayment Fees. When a member/borrower prepays an advance, the Bank could suffer lower future income if the principal portion of the prepaid advance is reinvested in lower-yielding assets. To protect against this risk, the Bank generally charges a prepayment fee that makes it financially indifferent to a borrower’s decision to prepay an advance. The Bank records prepayment fees received from members/borrowers on prepaid advances net of any associated hedging adjustments on those advances. These fees are reflected as interest income in the statements of income either immediately (as prepayment fees on advances) or over time (as interest income on advances) as further described below. In cases in which the Bank funds a new advance concurrent with or within a short period of time before or after the prepayment of an existing advance and the advance meets the accounting criteria to qualify as a modification of the prepaid advance, the net prepayment fee on the prepaid advance is deferred, recorded in the basis of the modified advance, and amortized into interest income over the life of the modified advance using the level-yield method. During the three months ended June 30, 2013 and 2012, gross advance prepayment fees received from members/borrowers were $9,396,000 and $2,145,000, respectively, of which $95,000 and $128,000, respectively, were deferred. During the six months ended June 30, 2013 and 2012, gross advance prepayment fees received from members/borrowers were $10,004,000 and $5,783,000, respectively, of which $246,000 and $432,000, respectively, were deferred.

Note 6—Allowance for Credit Losses

An allowance for credit losses is separately established for each of the Bank’s identified portfolio segments, if necessary, to provide for probable losses inherent in its financing receivables portfolio and other off-balance sheet credit exposures as of the balance sheet date. To the extent necessary, an allowance for credit losses for off-balance sheet credit exposures is recorded as a liability.

A portfolio segment is defined as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses. The Bank has developed and documented a systematic methodology for determining an allowance for credit losses for the following portfolio segments: (1) advances and other extensions of credit to members, collectively referred to as “extensions of credit to members;” (2) government-guaranteed/insured mortgage loans held for portfolio; and (3) conventional mortgage loans held for portfolio.

Classes of financing receivables are generally a disaggregation of a portfolio segment and are determined on the basis of their initial measurement attribute, the risk characteristics of the financing receivable and an entity’s method for monitoring and assessing credit risk. Because the credit risk arising from the Bank’s financing receivables is assessed and measured at the portfolio segment level, the Bank does not have separate classes of financing receivables within each of its portfolio segments.

During the six months ended June 30, 2013 and 2012, there were no purchases or sales of financing receivables, nor were any financing receivables reclassified to held for sale.

Advances and Other Extensions of Credit to Members. In accordance with federal statutes, including the Federal Home Loan Bank Act of 1932, as amended (the “FHLB Act”), the Bank lends to financial institutions within its five-state district that are involved in housing finance. The FHLB Act requires the Bank to obtain and maintain sufficient collateral for advances and other extensions of credit to protect against losses. The Bank makes advances and otherwise extends credit only against eligible collateral, as defined by regulation. To ensure the value of collateral pledged to the Bank is sufficient to secure its advances and other extensions of credit, the Bank applies various haircuts, or discounts, to the collateral to determine the value against which borrowers may borrow. As additional security, the Bank has a statutory lien on each borrower’s capital stock in the Bank.

On at least a quarterly basis, the Bank evaluates all outstanding extensions of credit to members/borrowers for potential credit losses. These evaluations include a review of: (1) the amount, type and performance of collateral available to secure the outstanding obligations; (2) metrics that may be indicative of changes in the financial condition and general creditworthiness of the member/borrower; and (3) the payment status of the obligations. Any outstanding extensions of credit that exhibit a potential credit weakness that could jeopardize the full collection of the outstanding obligations would be classified as substandard, doubtful or loss. The Bank did not have any advances or other extensions of credit to members/borrowers that were classified as substandard, doubtful or loss at June 30, 2013 or December 31, 2012.

The Bank considers the amount, type and performance of collateral to be the primary indicator of credit quality with respect to its extensions of credit to members/borrowers. At June 30, 2013 and December 31, 2012, the Bank had rights to collateral on a borrower-by-borrower basis with an estimated value in excess of each borrower’s outstanding extensions of credit.

The Bank continues to evaluate and, as necessary, modify its credit extension and collateral policies based on market conditions. At June 30, 2013 and December 31, 2012, the Bank did not have any advances that were past due, on non-accrual status, or considered impaired. There have been no troubled debt restructurings related to advances.

The Bank has never experienced a credit loss on an advance or any other extension of credit to a member/borrower and, based on its credit extension and collateral policies, management currently does not anticipate any credit losses on its extensions of credit to members/borrowers. Accordingly, the Bank has not provided any allowance for credit losses on advances, nor has it recorded any liabilities to reflect an allowance for credit losses related to its off-balance sheet credit exposures.

Mortgage Loans — Government-guaranteed/Insured. The Bank’s government-guaranteed/insured fixed-rate mortgage loans are insured or guaranteed by the Federal Housing Administration or the Department of Veterans Affairs. Any losses from these loans are expected to be recovered from those entities. Any losses from these loans that are not recovered from those entities are absorbed by the servicers. Therefore, the Bank has not established an allowance for credit losses on government-guaranteed/insured mortgage loans. Government-guaranteed/insured loans are not placed on non-accrual status.

Mortgage Loans — Conventional Mortgage Loans. The Bank’s conventional mortgage loans were acquired through the Mortgage Partnership Finance^® (“MPF”^®) program, as more fully described in the Bank’s 2012 10-K. The allowance for losses on conventional mortgage loans is determined by an analysis that includes consideration of various data such as past performance, current performance, loan portfolio characteristics, collateral-related characteristics, industry data, and prevailing economic conditions. The allowance for losses on conventional mortgage loans also factors in the credit enhancement under the MPF program. Any incurred losses that are expected to be recovered from the credit enhancements are not reserved as part of the Bank’s allowance for loan losses.

16

The Bank places a conventional mortgage loan on non-accrual status when the collection of the contractual principal or interest is 90 days or more past due. When a mortgage loan is placed on non-accrual status, accrued but uncollected interest is reversed against interest income. The Bank records cash payments received on non-accrual loans first as interest income until it recovers all interest, and then as a reduction of principal. A loan on non-accrual status may be restored to accrual status when (1) none of its contractual principal and interest is due and unpaid, and the Bank expects repayment of the remaining contractual interest and principal, or (2) the loan otherwise becomes well secured and in the process of collection.

A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement. Collateral-dependent loans that are on non-accrual status are measured for impairment based on the fair value of the underlying property less estimated selling costs. Loans are considered collateral-dependent if repayment is expected to be provided solely by the sale of the underlying property; that is, there is no other available and reliable source of repayment. A collateral-dependent loan is impaired if the fair value of the underlying collateral is insufficient to recover the unpaid principal and interest on the loan. Interest income on impaired loans is recognized in the same manner as it is for non-accrual loans noted above.

The Bank evaluates whether to record a charge-off on a conventional mortgage loan upon the occurrence of a confirming event. Confirming events include, but are not limited to, the occurrence of foreclosure or notification of a claim against any of the credit enhancements. A charge-off is recorded if the recorded investment in the loan will not be recovered.

The Bank considers the key credit quality indicator for conventional mortgage loans to be the payment status of each loan. The table below summarizes the unpaid principal balance by payment status for mortgage loans at June 30, 2013 and December 31, 2012 (dollars in thousands). The unpaid principal balance approximates the recorded investment in the loans.

At June 30, 2013 and December 31, 2012, the Bank’s other assets included $204,000 and $25,000, respectively, of real estate owned.

Mortgage loans are considered impaired when, based upon current information and events, it is probable that the Bank will be unable to collect all principal and interest amounts due according to the contractual terms of the mortgage loan agreement. Each non-accrual mortgage loan and each troubled debt restructuring is specifically reviewed for impairment. At June 30, 2013 and December 31, 2012, the estimated value of the collateral securing each of these loans was in excess of the outstanding loan amount. Therefore, no specific reserve was established for any of these mortgage loans. The remaining conventional mortgage loans were evaluated for impairment on a pool basis. Based upon the current and past performance of these loans, the underwriting standards in place at the time the loans were acquired, and current economic conditions, the Bank determined that an allowance for loan losses of $175,000 was adequate to reserve for credit losses in its conventional mortgage loan portfolio at

Note 7—Consolidated Obligations

Consolidated obligations are the joint and several obligations of the FHLBanks and consist of consolidated obligation bonds and discount notes. Consolidated obligations are backed only by the financial resources of the 12 FHLBanks. Consolidated obligations are not obligations of, nor are they guaranteed by, the U.S. government. The FHLBanks issue consolidated obligations through the Office of Finance as their agent. In connection with each debt issuance, one or more of the FHLBanks specifies the amount of debt it wants issued on its behalf; the Bank receives the proceeds only of the debt issued on its behalf and is the primary obligor only for the portion of bonds and discount notes for which it has received the proceeds. The Bank records on its statements of condition only that portion of the consolidated obligations for which it is the primary obligor. Consolidated obligation bonds are issued primarily to raise intermediate- and long-term funds for the FHLBanks and are not subject to any statutory or regulatory limits on maturity. Consolidated obligation discount notes are issued to raise short-term funds and have maturities of one year or less. These notes are issued at a price that is less than their face amount and are redeemed at par value when they mature. For additional information regarding the FHLBanks’ joint and several liability on consolidated obligations, see Note 14.

The par amounts of the 12 FHLBanks’ outstanding consolidated obligations, including consolidated obligations held as investments by other FHLBanks, were approximately $705 billion and $688 billion at June 30, 2013 and December 31, 2012, respectively. The Bank was the primary obligor on $29.8 billion and $32.6 billion (at par value), respectively, of these consolidated obligations.

Interest Rate Payment Terms. The following table summarizes the Bank’s consolidated obligation bonds outstanding by interest rate payment terms at June 30, 2013 and December 31, 2012 (in thousands, at par value).

Note 9—Assets and Liabilities Subject to Offsetting

The Bank has derivatives and securities purchased under agreements to resell that are subject to enforceable master netting arrangements. For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting arrangement (including any cash collateral remitted to or received from the counterparty). The Bank did not have any liabilities that were eligible to offset its securities purchased under agreements to resell (i.e., securities sold under agreements to repurchase) as of June 30, 2013 or December 31, 2012.

The Bank has entered into master agreements with each of its bilateral derivative counterparties that provide for the netting of all transactions with each of these counterparties. Under its master agreements with its non-member bilateral derivative counterparties, collateral is delivered (or returned) daily when certain thresholds (ranging from $100,000 to $500,000) are met. When entering into derivative transactions with its members, the Bank requires the member to post eligible collateral in an amount equal to the sum of the net market value of the member’s derivative transactions with the Bank (if the value is positive to the Bank) plus a percentage of the notional amount of any interest rate swaps, with market values determined on at least a monthly basis. Eligible collateral for derivative transactions with members consists of collateral that is eligible to secure advances and other obligations under the member's Advances and Security Agreement with the Bank. The Bank is not required to pledge collateral to its members to secure derivative positions.

The following table presents derivative instruments and securities purchased under agreements to resell with the legal right of offset, including the related collateral received from or pledged to counterparties as of June 30, 2013 and December 31, 2012, based on the terms of the Bank's master netting arrangements (in thousands).

Note 10—Derivatives and Hedging Activities

Hedging Activities. As a financial intermediary, the Bank is exposed to interest rate risk. This risk arises from a variety of financial instruments that the Bank enters into on a regular basis in the normal course of its business. The Bank enters into interest rate swap, swaption, cap and forward rate agreements (collectively, interest rate exchange agreements) to manage its exposure to changes in interest rates. The Bank may use these instruments to adjust the effective maturity, repricing frequency, or option characteristics of financial instruments to achieve risk management objectives. The Bank has not entered into any credit default swaps or foreign exchange-related derivatives, nor is it currently a party to any swaptions or forward rate agreements.

The Bank uses interest rate exchange agreements in two ways: either by designating the agreement as a fair value hedge of a specific financial instrument or firm commitment or by designating the agreement as a hedge of some defined risk in the course of its balance sheet management (referred to as an “economic hedge”). For example, the Bank uses interest rate exchange agreements in its overall interest rate risk management activities to adjust the interest rate sensitivity of consolidated obligations to approximate more closely the interest rate sensitivity of its assets (both advances and investments), and/or to adjust the interest rate sensitivity of advances or investments to approximate more closely the interest rate sensitivity of its liabilities. In addition to using interest rate exchange agreements to manage mismatches between the coupon features of its assets and liabilities, the Bank also uses interest rate exchange agreements to manage embedded options in assets and liabilities, to preserve the market value of existing assets and liabilities, to hedge the duration risk of prepayable instruments, to offset interest rate exchange agreements entered into with members (the Bank serves as an intermediary in these transactions), and to reduce funding costs.

The Bank, consistent with Finance Agency regulations, enters into interest rate exchange agreements only to reduce potential market risk exposures inherent in otherwise unhedged assets and liabilities or to act as an intermediary between its members and the Bank’s derivative counterparties. The Bank is not a derivatives dealer and it does not trade derivatives for short-term profit.

At inception, the Bank formally documents the relationships between derivatives designated as hedging instruments and their hedged items, its risk management objectives and strategies for undertaking the hedge transactions, and its method for assessing the effectiveness of the hedging relationships. This process includes linking all derivatives that are designated as fair value hedges to: (1) specific assets and liabilities on the statements of condition or (2) firm commitments. The Bank also formally assesses (both at the inception of the hedging relationship and on a monthly basis thereafter) whether the derivatives that are used in hedging transactions have been effective in offsetting changes in the fair value of hedged items and whether those derivatives may be expected to remain effective in future periods. The Bank uses regression analyses to assess the effectiveness of its hedges.

Investments — The Bank has invested in agency and non-agency MBS, all of which are classified as held-to-maturity. The interest rate and prepayment risk associated with these investment securities is managed through consolidated obligations and/or derivatives. The Bank may manage prepayment and duration risk presented by some investment securities with either callable or non-callable consolidated obligations or interest rate exchange agreements, including caps and interest rate swaps.

A substantial portion of the Bank’s held-to-maturity securities are variable-rate MBS that include caps that would limit the variable-rate coupons if short-term interest rates rise dramatically. To hedge a portion of the potential cap risk embedded in these securities, the Bank has entered into interest rate cap agreements. These derivatives are treated as economic hedges.

The Bank has also invested in agency and other highly rated debentures. Substantially all of the Bank's available-for-sale securities are fixed-rate debentures. To hedge the interest rate risk associated with these fixed-rate investment securities, the Bank entered into fixed-for-floating interest rate exchange agreements, which are designated as fair value hedges.

Advances — The Bank issues both fixed-rate and variable-rate advances. When appropriate, the Bank uses interest rate exchange agreements to adjust the interest rate sensitivity of its fixed-rate advances to approximate more closely the interest rate sensitivity of its liabilities. With issuances of putable advances, the Bank purchases from the member a put option that enables the Bank to terminate a fixed-rate advance on specified future dates. This embedded option is clearly and closely related to the host advance contract. The Bank typically hedges a putable advance by entering into a cancelable interest rate exchange agreement where the Bank pays a fixed coupon and receives a variable coupon, and sells an option to cancel the swap to the swap counterparty. This type of hedge is treated as a fair value hedge. The swap counterparty can cancel the interest rate exchange agreement on the call date and the Bank can cancel the putable advance and offer, subject to certain conditions, replacement funding at prevailing market rates.

A small portion of the Bank’s variable-rate advances are subject to interest rate caps that would limit the variable-rate coupons if short-term interest rates rise above a predetermined level. To hedge the cap risk embedded in these advances, the Bank generally enters into interest rate cap agreements. This type of hedge is treated as a fair value hedge.

22

The Bank may hedge a firm commitment for a forward-starting advance through the use of an interest rate swap. In this case, the swap will function as the hedging instrument for both the firm commitment and the subsequent advance. The carrying value of the firm commitment will be included in the basis of the advance at the time the commitment is terminated and the advance is issued. The basis adjustment will then be amortized into interest income over the life of the advance.

The Bank enters into optional advance commitments with its members. In an optional advance commitment, the Bank sells an option to the member that provides the member with the right to enter into an advance at a specified fixed rate and term on a specified future date, provided the member has satisfied all of the customary requirements for such advance. Optional advance commitments involving Community Investment Program (“CIP”) and Economic Development Program (“EDP”) advances with a commitment period of three months or less are currently provided at no cost to members. The Bank may hedge an optional advance commitment through the use of an interest rate swaption. In this case, the swaption will function as the hedging instrument for both the commitment and, if the option is exercised by the member, the subsequent advance. These swaptions are treated as economic hedges.

Consolidated Obligations— While consolidated obligations are the joint and several obligations of the FHLBanks, each FHLBank is the primary obligor for the consolidated obligations it has issued or assumed from another FHLBank. The Bank generally enters into derivative contracts to hedge the interest rate risk associated with its specific debt issuances.

To manage the interest rate risk of certain of its consolidated obligations, the Bank will match the cash outflow on a consolidated obligation with the cash inflow of an interest rate exchange agreement. With issuances of fixed-rate consolidated obligation bonds, the Bank typically enters into a matching interest rate exchange agreement in which the counterparty pays fixed cash flows to the Bank that are designed to mirror in timing and amount the cash outflows the Bank pays on the consolidated obligation. In this transaction, the Bank pays a variable cash flow that closely matches the interest payments it receives on short-term or variable-rate assets, typically one-month or three-month LIBOR. These transactions are treated as fair value hedges. On occasion, the Bank may enter into fixed-for-floating interest rate exchange agreements to hedge the interest rate risk associated with certain of its consolidated obligation discount notes. The derivatives associated with the Bank’s discount note hedging are treated as economic hedges. The Bank may also use interest rate exchange agreements to convert variable-rate consolidated obligation bonds from one index rate (e.g., the daily effective federal funds rate) to another index rate (e.g., one-month or three-month LIBOR); these transactions are treated as economic hedges.

The Bank has not issued consolidated obligations denominated in currencies other than U.S. dollars.

Balance Sheet Management — From time to time, the Bank may enter into interest rate basis swaps to reduce its exposure to changing spreads between one-month and three-month LIBOR. In addition, to reduce its exposure to reset risk, the Bank may occasionally enter into forward rate agreements. These derivatives are treated as economic hedges.

Intermediation — The Bank offers interest rate swaps, caps and floors to its members to assist them in meeting their hedging needs. In these transactions, the Bank acts as an intermediary for its members by entering into an interest rate exchange agreement with a member and then entering into an offsetting interest rate exchange agreement with one of the Bank’s approved derivative counterparties. All interest rate exchange agreements related to the Bank’s intermediary activities with its members are accounted for as economic hedges.

Accounting for Derivatives and Hedging Activities. The Bank accounts for derivatives and hedging activities in accordance with the guidance in Topic 815 of the FASB’s Accounting Standards Codification (“ASC”) entitled “Derivatives and Hedging” (“ASC 815”). All derivatives are recognized on the statements of condition at their fair values, including accrued interest receivable and payable. For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting arrangement (including any cash collateral remitted to or received from the counterparty).

Changes in the fair value of a derivative that is effective as — and that is designated and qualifies as — a fair value hedge, along with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk (including changes that reflect gains or losses on firm commitments), are recorded in current period earnings. Any hedge ineffectiveness (which represents the amount by which the change in the fair value of the derivative differs from the change in the fair value of the hedged item attributable to the hedged risk) is recorded in other income (loss) as “net gains (losses) on derivatives and hedging activities.” Net interest income/expense associated with derivatives that qualify for fair value hedge accounting under ASC 815 is recorded as a component of net interest income. An economic hedge is defined as a derivative hedging specific or non-specific assets or liabilities that does not qualify or was not designated for hedge accounting under ASC 815, but is an acceptable hedging strategy under the Bank’s Risk Management Policy. These hedging strategies also comply with Finance Agency regulatory requirements prohibiting speculative derivative transactions. An economic hedge by definition introduces the potential for earnings variability as changes in the fair value of a derivative designated as an economic hedge are recorded in current period earnings with no offsetting fair value adjustment to an asset or liability. Both the net interest income/expense and the fair value adjustments associated with derivatives in economic hedging relationships are recorded in other income (loss) as “net gains (losses) on derivatives and hedging activities.” Cash flows associated with derivatives are reported as cash flows from

23

operating activities in the statements of cash flows, unless the derivatives contain an other-than-insignificant financing element, in which case the cash flows are reported as cash flows from financing activities.

If hedging relationships meet certain criteria specified in ASC 815, they are eligible for hedge accounting and the offsetting changes in fair value of the hedged items may be recorded in earnings. The application of hedge accounting generally requires the Bank to evaluate the effectiveness of the hedging relationships on an ongoing basis and to calculate the changes in fair value of the derivatives and related hedged items independently. This is commonly known as the “long-haul” method of hedge accounting. Transactions that meet more stringent criteria qualify for the “shortcut” method of hedge accounting in which an assumption can be made that the change in fair value of a hedged item exactly offsets the change in value of the related derivative. The Bank considers hedges of committed advances to be eligible for the shortcut method of accounting as long as the settlement of the committed advance occurs within the shortest period possible for that type of instrument based on market settlement conventions, the fair value of the swap is zero at the inception of the hedging relationship, and the transaction meets all of the other criteria for shortcut accounting specified in ASC 815. The Bank has defined the market settlement convention to be five business days or less for advances. The Bank records the changes in fair value of the derivative and the hedged item beginning on the trade date.

The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is “embedded” and the financial instrument that embodies the embedded derivative instrument is not remeasured at fair value with changes in fair value reported in earnings as they occur. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as either (1) a hedging instrument in a fair value hedge or (2) a stand-alone derivative instrument pursuant to an economic hedge. However, if the entire contract were to be measured at fair value, with changes in fair value reported in current earnings, or if the Bank could not reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract would be carried on the statement of condition at fair value and no portion of the contract would be separately accounted for as a derivative.

The Bank discontinues hedge accounting prospectively when: (1) management determines that the derivative is no longer effective in offsetting changes in the fair value of a hedged item; (2) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (3) a hedged firm commitment no longer meets the definition of a firm commitment; or (4) management determines that designating the derivative as a hedging instrument in accordance with ASC 815 is no longer appropriate.

When fair value hedge accounting for a specific derivative is discontinued due to the Bank’s determination that such derivative no longer qualifies for hedge accounting treatment, the Bank will continue to carry the derivative on the statement of condition at its fair value, cease to adjust the hedged asset or liability for changes in fair value, and amortize the cumulative basis adjustment on the formerly hedged item into earnings over its remaining term using the level-yield method. In all cases in which hedge accounting is discontinued and the derivative remains outstanding, the Bank will carry the derivative at its fair value on the statement of condition, recognizing changes in the fair value of the derivative in current period earnings.

When hedge accounting is discontinued because the hedged item no longer meets the definition of a firm commitment, the Bank continues to carry the derivative on the statement of condition at its fair value, removing from the statement of condition any asset or liability that was recorded to recognize the firm commitment and recording it as a gain or loss in current period earnings.

⁽¹⁾  Reported as net gains (losses) on derivatives and hedging activities in the statements of income.

⁽²⁾  The net interest income (expense) associated with derivatives in ASC 815 fair value hedging relationships is reported in the statements of income in the interest income/expense line item for the indicated hedged item.

Credit Risk Related to Derivatives. The Bank is subject to credit risk due to the risk of nonperformance by counterparties to its derivative agreements. The Bank manages derivative counterparty credit risk through the use of master netting agreements or other collateral exchange arrangements, credit analysis, and adherence to the requirements set forth in the Bank’s Risk Management Policy and Finance Agency regulations. The Bank has transacted substantially all of its interest rate exchange agreements bilaterally with large financial institutions under master netting agreements. Some of these institutions (or their affiliates) buy, sell, and distribute consolidated obligations.

The notional amount of interest rate exchange agreements does not reflect the Bank’s credit risk exposure, which is much less than the notional amount. The Bank's net credit risk exposure is based on the current estimated cost, on a present value basis, of replacing at current market rates all interest rate exchange agreements with individual counterparties, if those counterparties were to default, after taking into account the value of any cash and/or securities collateral held or remitted by the Bank. For counterparties with which the Bank is in a net gain position, the Bank has credit exposure when the collateral it is holding (if any) has a value less than the amount of the gain. For counterparties with which the Bank is in a net loss position, the Bank has credit exposure when it has delivered collateral with a value greater than the amount of the loss position. The net exposure on bilateral derivative agreements is presented in Note 9. Based on the netting provisions and collateral requirements of its master agreements and the creditworthiness of its derivative counterparties, Bank management does not currently anticipate any credit losses on its derivative agreements.

Shareholders are required to maintain an investment in Class B stock equal to the sum of a membership investment requirement and an activity-based investment requirement. The membership investment requirement is currently 0.04 percent of each member's total assets as of December 31, 2012, subject to a minimum of $1,000 and a maximum of $7,000,000. The activity-based investment requirement is currently 4.10 percent of outstanding advances.

The Bank generally repurchases surplus stock on the last business day of the month following the end of each calendar quarter. For the repurchases that occurred on January 31, 2013, April 30, 2013 and July 31, 2013, surplus stock was defined as the amount of stock held by a member in excess of 102.5 percent of the member’s minimum investment requirement. For the repurchases that occurred on January 31, 2013, April 30, 2013 and July 31, 2013, a member's surplus stock was not repurchased if the amount of that member's surplus stock was $100,000 or less or if, subject to certain exceptions, the member was on restricted collateral status. On January 31, 2013, April 30, 2013 and July 31, 2013, the Bank repurchased surplus stock totaling $198,427,400, $168,555,900 and $182,879,400, respectively, none of which was classified as mandatorily redeemable capital stock at those dates.

Note 13—Estimated Fair Values

Fair value is defined under U.S. GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. U.S. GAAP establishes a fair value hierarchy and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. U.S. GAAP also requires an entity to disclose the level within the fair value hierarchy in which each measurement is classified. The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels:

Level 1 Inputs — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

28

Level 2 Inputs — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include the following: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active or in which little information is released publicly; (3) inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals and implied volatilities); and (4) inputs that are derived principally from or corroborated by observable market data (e.g., implied spreads).

Level 3 Inputs — Unobservable inputs for the asset or liability that are supported by little or no market activity. None of the Bank’s assets or liabilities that are recorded at fair value on a recurring basis were measured using significant Level 3 inputs.

The following estimated fair value amounts have been determined by the Bank using available market information and the Bank’s best judgment of appropriate valuation methods. These estimates are based on pertinent information available to the Bank as of June 30, 2013 and December 31, 2012. Although the Bank uses its best judgment in estimating the fair value of these financial instruments, there are inherent limitations in any estimation technique or valuation methodology. For example, because an active secondary market does not exist for many of the Bank’s financial instruments (e.g., advances, non-agency RMBS and mortgage loans held for portfolio), in certain cases their fair values are not subject to precise quantification or verification. Therefore, the estimated fair values presented below in the Fair Value Summary Tables may not be indicative of the amounts that would have been realized in market transactions at the reporting dates. Further, the fair values do not represent an estimate of the overall market value of the Bank as a going concern, which would take into account future business opportunities.

The valuation techniques used to measure the fair values of the Bank’s financial instruments are described below.

Cash and due from banks. The estimated fair value equals the carrying value.

Interest-bearing deposit assets. Interest-bearing deposit assets earn interest at floating market rates; therefore, the estimated fair value of the deposits approximates their carrying value.

  Securities purchased under agreements to resell and federal funds sold. All federal funds sold and securities purchased under agreements to resell represent overnight balances. The estimated fair values approximate the carrying values.

Trading securities. The Bank obtains quoted prices for identical securities.

Available-for-sale and held-to-maturity securities. To value its available-for-sale securities and its held-to-maturity MBS holdings, the Bank obtains prices from four designated third-party pricing vendors when available. The pricing vendors use various proprietary models to price these securities. The inputs to those models are derived from various sources including, but not limited to: benchmark yields, reported trades, dealer estimates, issuer spreads, benchmark securities, bids, offers and other market-related data. Because many securities do not trade on a daily basis, the pricing vendors use available information as applicable such as benchmark curves, benchmarking of like securities, sector groupings and matrix pricing to determine the prices for individual securities. Each pricing vendor has an established challenge process in place for all security valuations, which facilitates resolution of potentially erroneous prices identified by the Bank.

A "median" price is first established for each security using a formula that is based upon the number of prices received. If four prices are received, the average of the middle two prices is the median price; if three prices are received, the middle price is the median price; if two prices are received, the average of the two prices is the median price; and if one price is received, it is the median price (and also the final price) subject to some type of validation similar to the evaluation of outliers described below. All prices that are within a specified tolerance threshold of the median price are included in the “cluster” of prices that are averaged to compute a “default” price. All prices that are outside the threshold (“outliers”) are subject to further analysis (including, but not limited to, comparison to prices provided by an additional third-party valuation service, prices for similar securities, and/or non-binding dealer estimates) to determine if an outlier is a better estimate of fair value. If an outlier (or some other price identified in the analysis) is determined to be a better estimate of fair value, then the outlier (or the other price, as appropriate) is used as the final price rather than the default price. If, on the other hand, the analysis confirms that an outlier (or outliers) is (are) in fact not representative of fair value and the default price is the best estimate, then the default price is used as the final price. In all cases, the final price is used to determine the fair value of the security.

If all prices received for a security are outside the tolerance threshold level of the median price, then there is no default price, and the final price is determined by an evaluation of all outlier prices as described above.

As an additional step, the Bank reviewed the final fair value estimates of its non-agency RMBS holdings as of June 30, 2013 for reasonableness using an implied yield test. The Bank calculated an implied yield for each of its non-agency RMBS using the estimated fair value derived from the process described above and the security's projected cash flows from the Bank's OTTI process and compared those yields to the yields for comparable securities according to dealers and other third-party

29

sources to the extent comparable market yield data was available. This analysis did not indicate that any adjustments to the final fair value estimates were necessary.

As of June 30, 2013, four vendor prices were received for substantially all of the Bank’s available-for-sale securities and held-to-maturity MBS holdings and the final prices for substantially all of those securities were computed by averaging the four prices. Based on the Bank's understanding of the pricing methods employed by the third-party pricing vendors and the relative lack of dispersion among the vendor prices (or, in those instances in which there were outliers or significant yield variances, the Bank's additional analyses), the Bank believes its final prices result in reasonable estimates of the fair values and that the fair value measurements are classified appropriately in the fair value hierarchy.

The Bank estimates the fair values of its held-to-maturity debentures using a pricing model and observable market data (i.e., the U.S. Government Agency Fair Value curve and, for debentures containing call features, swaption volatility).

Advances. The Bank determines the estimated fair values of advances by calculating the present value of expected future cash flows from the advances using the replacement advance rates for advances with similar terms and, for advances containing options, swaption volatility. This amount is then reduced for accrued interest receivable. Each FHLBank prices advances at a spread to its cost of funds. Each FHLBank's cost of funds approximates the "CO curve," which is derived by adding to the U.S. Treasury curve indicative spreads obtained from market-observable sources. The indicative spreads are generally derived from dealer pricing indications, recent trades, secondary market activity and historical pricing relationships.

Mortgage loans held for portfolio. The Bank estimates the fair values of mortgage loans held for portfolio based on observed market prices for agency MBS. Individual mortgage loans are pooled based on certain criteria such as loan type, weighted average coupon, and origination year and matched to reference securities with a similar collateral composition to derive benchmark pricing. The prices for agency MBS used as a benchmark are subject to certain market conditions including, but not limited to, the market’s expectations of future prepayments, the current and expected level of interest rates, and investor demand.

Accrued interest receivable and payable. The estimated fair value of accrued interest receivable and payable approximates the carrying value due to their short-term nature.

Derivative assets/liabilities. With the exception of its interest rate basis swaps, the fair values of the Bank’s interest rate swap and swaption agreements are estimated using a pricing model with inputs that are observable in the market (e.g., the relevant interest rate curves (that is, the relevant LIBOR swap curve and, for purposes of discounting, the overnight index swap ("OIS") curve) and, for agreements containing options, swaption volatility). Prior to December 31, 2012, the Bank used the LIBOR swap curve to discount cash flows when determining the fair values of its interest rate exchange agreements. The Bank determined that most market participants had as of December 31, 2012 begun using the OIS curve to value certain collateralized interest rate exchange agreements and, as a result, the Bank concluded that the OIS curve was a more appropriate curve to use to discount the cash flows on its interest rate exchange agreements beginning on that date.

As the provisions of the credit support annexes to the Bank’s master agreements with its derivative counterparties significantly reduce the risk from nonperformance (see Note 9), the Bank does not consider its own nonperformance risk or the nonperformance risk associated with each of its counterparties to be a significant factor in the valuation of its derivative assets and liabilities. The Bank compares the fair values obtained from its pricing model to non-binding dealer estimates and may also compare its fair values to those of similar instruments to ensure that the fair values are reasonable. For the Bank’s interest rate basis swaps, fair values are obtained from dealers (for each basis swap, one dealer estimate is received); the non-binding fair value estimates as of June 30, 2013 and December 31, 2012 were corroborated using a pricing model and observable market data (i.e., the relevant LIBOR swap curve and, for purposes of discounting, the OIS curve).

For the Bank’s interest rate caps, fair values are obtained from dealers (for each interest rate cap, one dealer estimate is received). The non-binding fair value estimates as of June 30, 2013 and December 31, 2012 were corroborated using a pricing model and observable market data (i.e., cap volatility, the relevant LIBOR swap curve and, for purposes of discounting, the OIS curve).

The fair values of the Bank’s derivative assets and liabilities include accrued interest receivable/payable and, in the case of derivatives executed under master netting arrangements, cash collateral remitted to/received from counterparties; the estimated fair values of the accrued interest receivable/payable and cash collateral approximate their carrying values due to their short-term nature. The fair values of the Bank's bilateral derivatives are netted by counterparty pursuant to the provisions of the credit support annexes to the Bank’s master agreements with its non-member bilateral derivative counterparties. If these netted amounts are positive, they are classified as an asset and, if negative, as a liability.

Deposit liabilities. The Bank determines the estimated fair values of its deposit liabilities with fixed rates and more than three months to maturity by calculating the present value of expected future cash flows from the deposits and reducing this amount for accrued interest payable. The discount rates used in these calculations are based on replacement funding rates for

30

liabilities with similar terms. The estimated fair value approximates the carrying value for deposits with variable rates and fixed rates with three months or less to their maturity or repricing date.

Consolidated obligations. The Bank estimates the fair values of consolidated obligations by calculating the present value of expected future cash flows using discount rates that are based on replacement funding rates for liabilities with similar terms and reducing this amount for accrued interest payable. The inputs to the valuation are the CO curve and, for consolidated obligations containing options, swaption volatility.

Mandatorily redeemable capital stock. The fair value of capital stock subject to mandatory redemption is generally equal to its par value ($100 per share), as adjusted for any estimated dividend earned but unpaid at the time of reclassification from equity to liabilities. The Bank’s capital stock cannot, by statute or implementing regulation, be purchased, redeemed, repurchased or transferred at any amount other than its par value.

Commitments. The Bank determined the estimated fair values of optional commitments to fund advances by calculating the present value of expected future cash flows from the instruments using replacement advance rates for advances with similar terms and swaption volatility. The estimated fair value of the Bank’s other commitments to extend credit, including advances and letters of credit, was not material at June 30, 2013 or December 31, 2012.

The following table presents the carrying values and estimated fair values of the Bank’s financial instruments at June 30, 2013 (in thousands), as well as the level within the fair value hierarchy in which the measurements are classified. Financial assets and liabilities are classified in their entirety based on the lowest level input that is significant to the fair value estimate.

As of December 31, 2012, the Bank had entered into optional advance commitments with par values totaling $50,000,000, excluding commitments to fund CIP and EDP advances. These commitments expired during the three months ended March 31, 2013. Under each of these commitments, the Bank sold an option to a member that provided the member with the right to enter into an advance at a specified fixed rate and term on a specified future date, provided the member had satisfied all of the customary requirements for that advance. The Bank hedged these commitments through the use of interest rate swaptions, which were treated as economic hedges. The Bank irrevocably elected to carry these optional advance commitments at fair value under the fair value option in an effort to mitigate the potential income statement volatility that can arise from economic hedging relationships. Gains and losses on optional advance commitments carried at fair value under the fair value option are reported in other income (loss) in the statements of income. The optional advance commitments were reported in other liabilities in the statement of condition as of December 31, 2012. At December 31, 2012, the fair value of these optional advance commitments totaled less than $1,000. At that same date, other liabilities included items with an aggregate carrying value of $25,085,000 that were not eligible for the fair value option.

Note 14—Commitments and Contingencies

Joint and several liability. The Bank is jointly and severally liable with the other 11 FHLBanks for the payment of principal and interest on all of the consolidated obligations issued by the 12 FHLBanks. At June 30, 2013, the par amount of the other 11 FHLBanks’ outstanding consolidated obligations was approximately $675 billion. The Finance Agency, in its discretion, may require any FHLBank to make principal or interest payments due on any consolidated obligation, regardless of whether there has been a default by a FHLBank having primary liability. To the extent that a FHLBank makes any consolidated obligation payment on behalf of another FHLBank, the paying FHLBank is entitled to reimbursement from the FHLBank with primary liability. However, if the Finance Agency determines that the primary obligor is unable to satisfy its obligations, then the Finance Agency may allocate the outstanding liability among the remaining FHLBanks on a pro rata basis in proportion to each FHLBank’s participation in all consolidated obligations outstanding, or on any other basis that the Finance Agency may determine. No FHLBank has ever failed to make any payment on a consolidated obligation for which it was the primary obligor; as a result, the regulatory provisions for directing other FHLBanks to make payments on behalf of another FHLBank or allocating the liability among other FHLBanks have never been invoked. If the Bank were to determine that a loss was probable under its joint and several liability and the amount of such loss could be reasonably estimated, the Bank would charge to income the amount of the expected loss. Based upon the creditworthiness of the other FHLBanks, the Bank currently believes that the likelihood of a loss arising from its joint and several liability is remote.

Other commitments and contingencies. At June 30, 2013 and December 31, 2012, the Bank had commitments to make additional advances totaling approximately $35,663,000 and $77,212,000, respectively. In addition, outstanding standby letters of credit totaled $2,999,341,000 and $2,947,267,000 at June 30, 2013 and December 31, 2012, respectively. Based on management’s credit analyses and collateral requirements, the Bank does not deem it necessary to have any provision for credit losses on these letters of credit (see Note 6).

At June 30, 2013, the Bank had a commitment to issue a $40,000,000 consolidated obligation bond, which was hedged with an interest rate swap. The Bank did not have any commitments to issue consolidated obligations at December 31, 2012.

The Bank has executed interest rate exchange agreements with large financial institutions with which it has bilateral collateral exchange agreements. As of June 30, 2013 and December 31, 2012, the Bank had pledged cash collateral of $972,207,000 and $1,228,375,000, respectively, to those financial institutions that had credit risk exposure to the Bank related to interest rate exchange agreements. The pledged cash collateral (i.e., interest-bearing deposit asset) is netted against derivative assets and liabilities in the statements of condition.

In the ordinary course of its business, the Bank is subject to the risk that litigation may arise. Currently, the Bank is not a party to any material pending legal proceedings.

Note 15— Transactions with Shareholders

Affiliates of two of the Bank’s derivative counterparties (Citigroup and Wells Fargo) acquired member institutions on March 31, 2005 and October 1, 2006, respectively. Since the acquisitions were completed, the Bank has continued to enter into interest rate exchange agreements with Citigroup and Wells Fargo in the normal course of business and under the same terms and conditions as before. Effective October 1, 2006, Citigroup terminated the Ninth District charter of the affiliate that acquired the member institution and, as a result, an affiliate of Citigroup became a non-member shareholder of the Bank.

Note 16 — Transactions with Other FHLBanks

Occasionally, the Bank loans (or borrows) short-term federal funds to (or from) other FHLBanks. During the six months ended June 30, 2013 and 2012, interest income from loans to other FHLBanks totaled $1,507 and $744, respectively. The following table summarizes the Bank’s loans to other FHLBanks during the six months ended June 30, 2013 and 2012 (in thousands).

The Bank has, from time to time, assumed the outstanding debt of another FHLBank rather than issue new debt. In connection with these transactions, the Bank becomes the primary obligor for the transferred debt. The Bank did not assume any debt from other FHLBanks during the six months ended June 30, 2013 or 2012.

Occasionally, the Bank transfers debt to other FHLBanks. In connection with these transactions, the assuming FHLBank becomes the primary obligor for the transferred debt. The Bank did not transfer any debt to other FHLBanks during the six months ended June 30, 2013 or 2012.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of financial condition and results of operations should be read in conjunction with the financial statements and notes thereto included in “Item 1. Financial Statements.”

Forward-Looking Information

This quarterly report contains forward-looking statements that reflect current beliefs and expectations of the Federal Home Loan Bank of Dallas (the “Bank”) about its future results, performance, liquidity, financial condition, prospects and opportunities. These statements are identified by the use of forward-looking terminology, such as “anticipates,” “plans,” “believes,” “could,” “estimates,” “may,” “should,” “would,” “will,” “might,” “expects,” “intends” or their negatives or other similar terms. The Bank cautions that forward-looking statements involve risks or uncertainties that could cause the Bank’s actual results to differ materially from those expressed or implied in these forward-looking statements, or could affect the extent to which a particular objective, projection, estimate, or prediction is realized. As a result, undue reliance should not be placed on these statements.

These risks and uncertainties include, without limitation, evolving economic and market conditions, political events, and the impact of competitive business forces. The risks and uncertainties related to evolving economic and market conditions include, but are not limited to, changes in interest rates, changes in the Bank’s access to the capital markets, changes in the cost of the Bank’s debt, changes in the ratings on the Bank’s debt, adverse consequences resulting from a significant regional, national or global economic downturn (including, but not limited to, reduced demand for the Bank's products and services), credit and prepayment risks, or changes in the financial health of the Bank’s members or non-member borrowers. Among other things, political events could possibly lead to changes in the Bank’s regulatory environment or its status as a government-sponsored enterprise (“GSE”), or to changes in the regulatory environment for the Bank’s members or non-member borrowers. Risks and uncertainties related to competitive business forces include, but are not limited to, the potential loss of a significant amount of member borrowings through acquisitions or other means or changes in the relative competitiveness of the Bank’s products and services for member institutions. For a more detailed discussion of the risk factors applicable to the Bank, see “Item 1A — Risk Factors” in the Bank’s Annual Report on Form 10-K for the year ended December 31, 2012, which was filed with the Securities and Exchange Commission (“SEC”) on March 25, 2013 (the “2012 10-K”). The Bank undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, changed circumstances, or any other reason.

Overview

Business

The Bank is one of 12 district Federal Home Loan Banks (each individually a “FHLBank” and collectively the “FHLBanks” and, together with the Federal Home Loan Banks Office of Finance ("Office of Finance"), a joint office of the FHLBanks, the “FHLBank System”) that were created by the Federal Home Loan Bank Act of 1932. The FHLBanks serve the public by enhancing the availability of credit for residential mortgages, community lending, and targeted community development. As independent, member-owned cooperatives, the FHLBanks seek to maintain a balance between their public purpose and their ability to provide adequate returns on the capital supplied by their members. The Federal Housing Finance Agency (“Finance Agency”), an independent agency in the executive branch of the U.S. government, is responsible for supervising and regulating the FHLBanks and the Office of Finance. The Finance Agency’s stated mission is to ensure that the housing GSEs, including the FHLBanks, operate in a safe and sound manner so that they serve as a reliable source of liquidity and funding for housing finance and community investment. Consistent with this mission, the Finance Agency establishes policies and regulations covering the operations of the FHLBanks.

The Bank serves eligible financial institutions in Arkansas, Louisiana, Mississippi, New Mexico and Texas (collectively, the Ninth District of the FHLBank System). The Bank’s primary business is lending relatively low cost funds (known as advances) to its member institutions, which include commercial banks, thrifts, insurance companies, credit unions, and Community Development Financial Institutions that are certified under the Community Development Banking and Financial Institutions Act of 1994. While not members of the Bank, housing associates, including state and local housing authorities, that meet certain statutory criteria may also borrow from the Bank. The Bank also maintains a portfolio of investments, the vast majority of which are highly rated, for liquidity purposes and to provide additional earnings. Additionally, the Bank holds interests in a small and declining portfolio of government-guaranteed/insured and conventional mortgage loans that were acquired during the period from 1998 to mid-2003 through the Mortgage Partnership Finance^® (“MPF”^®) Program offered by the FHLBank of Chicago. Shareholders’ return on their investment includes dividends (which are typically paid quarterly in the form of capital stock) and the value derived from access to the Bank’s products and services. Historically, the Bank has balanced the financial rewards to shareholders by seeking to pay a dividend that meets or exceeds the return on alternative short-term money market investments available to shareholders, while lending funds at the lowest rates expected to be compatible with that objective and its objective to build retained earnings over time.

37

The Bank’s capital stock is not publicly traded and can be held only by members of the Bank, by non-member institutions that acquire stock by virtue of acquiring member institutions, by a federal or state agency or insurer acting as a receiver of a closed institution, or by former members of the Bank that retain capital stock to support advances or other activity that remains outstanding or until any applicable stock redemption or withdrawal notice period expires. All members must hold stock in the Bank. The Bank’s capital stock has a par value of $100 per share and is purchased, redeemed, repurchased and transferred only at its par value. By regulation, the parties to a transaction involving the Bank's stock can include only the Bank and its member institutions (or non-member institutions or former members, as described above). While a member could transfer stock to another member of the Bank, that transfer could occur only upon approval of the Bank and then only at par value. Members may redeem excess stock, or withdraw from membership and redeem all outstanding capital stock, with five years’ written notice to the Bank.

The FHLBanks’ debt instruments (known as consolidated obligations) are their primary source of funds and are the joint and several obligations of all 12 FHLBanks. Consolidated obligations are issued through the Office of Finance acting as agent for the FHLBanks and generally are publicly traded in the over-the-counter market. The Bank records on its statements of condition only those consolidated obligations for which it is the primary obligor. Consolidated obligations are not obligations of the U.S. government and the U.S. government does not guarantee them. Consolidated obligations are currently rated Aaa/P-1 by Moody’s Investors Service (“Moody’s”) and AA+/A-1+ by Standard & Poor’s (“S&P”). Each of these nationally recognized statistical rating organizations (“NRSROs”) recently changed its outlook on its long-term rating on the consolidated obligations from negative to stable, consistent with the change in each of the NRSRO's outlook on the long-term rating of the U.S. government from negative to stable. These ratings indicate that Moody’s and S&P have concluded that the FHLBanks have a very strong capacity to meet their commitments to pay principal and interest on consolidated obligations. The ratings also reflect the FHLBank System’s status as a GSE. Historically, the FHLBanks’ GSE status and very high credit ratings on consolidated obligations have provided the FHLBanks with excellent capital markets access. Deposits, other borrowings and the proceeds from capital stock issued to members are also sources of funds for the Bank.

In addition to ratings on the FHLBanks’ consolidated obligations, each FHLBank is rated individually by both S&P and Moody’s. These individual FHLBank ratings apply to the individual obligations of the respective FHLBanks, such as interest rate derivatives, deposits, and letters of credit. As of June 30, 2013, Moody’s had assigned a deposit rating of Aaa/P-1 to each of the FHLBanks. At that same date, S&P had rated 11 of the FHLBanks AA+/A-1+ and the FHLBank of Seattle AA/A-1+. The outlook on each of the NRSRO’s long-term ratings of the individual FHLBanks was recently changed from negative to stable, consistent with the change in each of the NRSRO's outlook on the long-term rating of the U.S. government from negative to stable.

Shareholders, bondholders and prospective shareholders and bondholders should understand that these credit ratings are not a recommendation to buy, hold or sell securities and they may be subject to revision or withdrawal at any time by the NRSRO. The ratings from each of the NRSROs should be evaluated independently.

The Bank conducts its business and fulfills its public purpose primarily by acting as a financial intermediary between its members and the capital markets. The intermediation of the timing, structure, and amount of its members’ credit needs with the investment requirements of the Bank’s creditors is made possible by the extensive use of interest rate exchange agreements, including interest rate swaps and caps. The Bank’s interest rate exchange agreements are accounted for in accordance with the provisions of Topic 815 of the Financial Accounting Standards Board Accounting Standards Codification entitled “Derivatives and Hedging.”

The Bank defines “adjusted earnings” as net earnings exclusive of: (1) gains or losses on the sales of investment securities, if any; (2) gains or losses on the retirement or transfer of debt, if any; (3) prepayment fees on advances; (4) fair value adjustments (except for net interest settlements) associated with derivatives and hedging activities and assets and liabilities carried at fair value; and (5) realized gains and losses associated with early terminations of derivative transactions. The Bank’s adjusted earnings are generated primarily from net interest income and typically tend to rise and fall with the overall level of interest rates, particularly short-term money market rates. Because the Bank is a cooperatively owned wholesale institution, the spread component of its net interest income is much smaller than a typical commercial bank. The Bank endeavors to maintain a fairly neutral interest rate risk profile. As a result, the Bank’s capital is effectively invested in shorter-term assets or assets with short repricing intervals, and its adjusted earnings and returns on capital stock (based on adjusted earnings) generally tend to track short-term interest rates.

The Bank’s profitability objective is to achieve a rate of return on members’ capital stock investment sufficient to allow the Bank to meet its retained earnings growth objectives and pay dividends on capital stock at rates that equal or exceed the average federal funds rate. The Bank’s quarterly dividends are based upon its operating results, shareholders’ average capital stock holdings and, currently, the upper end of the targeted range for the federal funds rate for the immediately preceding quarter. While the Bank has had a long-standing practice of paying quarterly dividends, future dividend payments cannot be assured.

38

The Bank operates in only one reportable segment. All of the Bank’s revenues are derived from U.S. operations.

The following table summarizes the Bank’s membership, by type of institution, as of June 30, 2013 and December 31, 2012.

For 2012, CFIs were defined as FDIC-insured institutions with average total assets as of December 31, 2011, 2010 and 2009 of less than $1.076 billion.

Financial Market Conditions

Economic conditions in the United States continued to show signs of improvement during the first six months of 2013. The gross domestic product increased at an annual rate of 1.7 percent during the second quarter of 2013, as compared to annual rates of 1.1 percent during the first quarter of 2013 and 2.8 percent during 2012. The nationwide unemployment rate fell from 7.8 percent at the end of 2012 to 7.6 percent at both March 31, 2013 and June 30, 2013. Housing prices have improved in most major metropolitan areas; however, some housing markets remain relatively weak. Despite the continued economic improvement during the first six months of the year, the sustainability and extent of those improvements and the prospects for and potential timing of further improvements remain uncertain.

Credit market conditions remained relatively stable during the first six months of 2013. The markets were impacted by concerns regarding the U.S. government's debt limit and deficits. In January 2013, in order to avoid the possible financial market impacts of an ongoing debt ceiling debate, the U.S. Congress passed a suspension of the debt ceiling until May 2013, temporarily averting market concerns of a U.S. government default. Currently, due to the impact of sequestration, higher than projected tax revenues and earnings and related dividend payments to the U.S. Treasury by the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac"), the U.S government is projected to remain below the debt ceiling until October or November of 2013.

In July 2013, the Federal Reserve announced that it would continue to purchase additional agency mortgage-backed securities ("MBS") at a pace of $40 billion per month and longer-term U.S. Treasury securities at a pace of $45 billion per month. The Federal Reserve also announced that it would maintain its existing policy of reinvesting the principal payments from its holdings of agency debt and agency MBS in agency MBS and of rolling over maturing treasury securities at auction. However, in the second quarter of 2013, due to fears that the Federal Reserve could begin to remove this quantitative easing, investors began to sell long-term Treasury bonds, which resulted in an increase in long-term interest rates.

The Federal Open Market Committee ("FOMC") maintained its target for the federal funds rate at a range between 0 and 0.25 percent throughout the first six months of 2013. The Federal Reserve stated at its July 2013 FOMC meeting that it currently anticipates that this exceptionally low range for the federal funds rate will be appropriate at least as long as the unemployment rate remains above 6.5 percent, inflation between one and two years ahead is projected to be no more than a half percentage point above the FOMC’s 2 percent longer-run goal, and longer-term inflation expectations continue to be well anchored. From 2009 through the second quarter of 2013, the Federal Reserve has paid interest on required and excess reserves

39

held by depository institutions at a rate of 0.25 percent, equivalent to the upper boundary of the target range for federal funds. During this period, a significant and sustained increase in bank reserves combined with the rate of interest being paid on those reserves has contributed to a decline in the volume of transactions taking place in the overnight federal funds market and an effective federal funds rate that has generally been below the upper end of the targeted range.

One-month and three-month LIBOR rates decreased slightly during the first six months of 2013, with one-month and three-month LIBOR ending the second quarter at 0.19 percent and 0.27 percent, respectively, as compared to 0.21 percent and 0.31 percent, respectively, at the end of 2012. The following table presents information on various market interest rates at June 30, 2013 and December 31, 2012 and various average market interest rates for the three and six-month periods ended June 30, 2013 and 2012.

Year-to-Date 2013 Summary

• The Bank ended the second quarter of 2013 with total assets of $32.7 billion compared with $35.8 billion at the end of 2012. The $3.1 billion decrease in total assets during the six-month period was attributable primarily to a $2.5 billion decrease in the Bank's short-term liquidity holdings and a $0.5 billion decrease in the Bank's long-term investments.

• Total advances were $18.4 billion at both June 30, 2013 and December 31, 2012. The Bank's lending activities remained subdued during the six-month period due largely to high deposit levels and weak demand for loans at member institutions.

• The Bank’s net income for the three and six months ended June 30, 2013 was $22.1 million and $40.2 million, respectively, including net interest income of $36.5 million and $71.3 million, respectively, and $3.1 million and $4.9 million, respectively, in net gains on derivatives and hedging activities.

• The Bank held $4.2 billion (notional) of interest rate swaps recorded as economic hedge derivatives with a net positive fair value of $13.1 million (excluding accrued interest) at June 30, 2013. If these derivatives are held to maturity, their values will ultimately decline to zero and be recorded as losses in future periods. The timing of these losses will depend upon a number of factors, including the relative level and volatility of future interest rates.

• Unrealized losses on the Bank’s holdings of non-agency residential MBS ("RMBS"), all of which are classified as held-to-maturity, totaled $23.1 million (11 percent of amortized cost) at June 30, 2013, as compared to $35.2 million (15 percent of amortized cost) at December 31, 2012. Based on its quarter-end analysis of the 30 securities in this portfolio, the Bank believes that the unrealized losses 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. Accordingly, no credit-related other-than-temporary impairment charges were recorded during the three months ended June 30, 2013. For a discussion of the Bank’s analysis, see “Item 1. Financial Statements” (specifically, Note 4 beginning on page 9 of this report). If the actual and/or projected performance of the loans underlying the

40

Bank’s holdings of non-agency RMBS deteriorates beyond management's current expectations, the Bank could recognize further losses on the securities that it has already determined to be other-than-temporarily impaired in prior periods and/or losses on its other investments in non-agency RMBS.

• At all times during the first six months of 2013, the Bank was in compliance with all of its regulatory capital requirements. In addition, the Bank’s retained earnings increased to $609.9 million (or 1.9 percent of total assets) at June 30, 2013 from $571.9 million (or 1.6 percent of total assets) at December 31, 2012.

• During the first six months of 2013, the Bank paid dividends totaling $2.2 million; the Bank’s first and second quarter dividends were each paid at an annualized rate of 0.375 percent, which exceeded the upper end of the Federal Reserve’s target for the federal funds rate of 0.25 percent for each of the preceding quarters by 12.5 basis points.

• While the Bank cannot predict future economic conditions, it does not expect that its advances balances will increase significantly for some period of time. Therefore, its future adjusted earnings will likely be lower than they would have been otherwise. As advances are paid off, the Bank's general practice is to repurchase capital stock in proportion to the reduction in outstanding advances. The Bank expects that its ability to adjust its capital levels in response to changes in the amount of advances outstanding combined with the accumulation of retained earnings in recent years will help to mitigate the negative impact that the current subdued lending activity would otherwise be expected to have on the Bank’s shareholders. While there can be no assurances, based on its current expectations the Bank anticipates that its earnings will be sufficient both to continue paying quarterly dividends at a rate equal to or slightly above the upper end of the target range for the federal funds rate and to continue building retained earnings for the foreseeable future. In addition, the Bank currently expects to continue its quarterly repurchases of surplus stock.

⁽¹⁾  Investments consist of federal funds sold, interest-bearing deposits, securities purchased under agreements to resell and securities classified as held-to-maturity, available-for-sale, and trading.

⁽²⁾  The Bank is jointly and severally liable with the other FHLBanks for the payment of principal and interest on the consolidated obligations of all of the FHLBanks. At June 30, 2013, March 31, 2013, December 31, 2012, September 30, 2012, and June 30, 2012, the outstanding consolidated obligations (at par value) of all 12 FHLBanks totaled approximately $705 billion, $666 billion, $688 billion, $674 billion, and $685 billion, respectively. As of those dates, the Bank’s outstanding consolidated obligations (at par value) were $30 billion, $28 billion, $33 billion, $32 billion, and $31 billion, respectively.

⁽³⁾  Mandatorily redeemable capital stock represents capital stock that is classified as a liability under generally accepted accounting principles. Dividends on mandatorily redeemable capital stock are recorded as interest expense and excluded from dividends paid. Dividends paid on mandatorily redeemable capital stock totaled $4 thousand, $5 thousand, $4 thousand, $5 thousand, and $7 thousand for the quarters ended June 30, 2013, March 31, 2013, December 31, 2012, September 30, 2012, and June 30, 2012, respectively.

⁽⁴⁾  Net interest income excludes the net interest income/expense associated with interest rate exchange agreements that do not qualify for hedge accounting. The net interest income associated with such agreements totaled $0.9 million, $1.3 million, $2.1 million, $2.5 million, and $2.9 million for the quarters ended June 30, 2013, March 31, 2013, December 31, 2012, September 30, 2012, and June 30, 2012, respectively.

⁽⁵⁾  Net interest margin is net interest income as a percentage of average earning assets.

⁽⁶⁾  Return on average capital stock is derived by dividing net income by average capital stock balances excluding mandatorily redeemable capital stock.

⁽⁷⁾  The regulatory capital ratio is computed by dividing regulatory capital (the sum of capital stock — putable, mandatorily redeemable capital stock and retained earnings) by total assets at each quarter-end.

⁽⁸⁾  Dividend payout ratio is computed by dividing dividends paid by net income for each quarter.

On May 14, 2013, the Finance Agency published an interim final rule setting forth requirements and processes with respect to compensation provided to FHLBank executive officers. The Executive Compensation interim final rule addresses the authority of the Finance Agency Director to approve, disapprove, modify, prohibit, or withhold compensation of FHLBank executive officers. The interim final rule also addresses the Finance Agency Director's authority to approve, in advance, agreements or contracts with executive officers that provide compensation in connection with a termination of employment. The interim final rule prohibits a FHLBank from paying compensation to an executive officer that is not reasonable and comparable with compensation paid by similar businesses for similar duties and responsibilities. The interim final rule became effective on June 13, 2013, and comments were due by July 15, 2013.

Proposed Rule Regarding Golden Parachute and Indemnification Payments

On May 14, 2013, the Finance Agency re-proposed a rule that would set forth the standards it would take into consideration when limiting or prohibiting golden parachute and indemnification payments by a FHLBank. The primary impact of this proposed rule would be to better conform existing Finance Agency regulations on golden parachutes with FDIC golden parachute regulations and to further limit any such payments made by a FHLBank that is assigned a less than satisfactory composite Finance Agency examination rating. Comments on the proposed rule were due by July 15, 2013.

Housing Finance and Housing GSE Reform

Congress continues to consider reforms for the U.S. housing finance system and the housing GSEs, including the resolution of Fannie Mae and Freddie Mac (together, the “Enterprises”). Several new proposals have been offered that would wind down the Enterprises and replace them with a new finance system to support the secondary mortgage market. On June 25, 2013, a bill entitled the Housing Finance Reform and Taxpayer Protection Actof 2013 (the “Housing Finance Reform Act”) was introduced in the Senate with bipartisan support. On July 11, 2013, Republican leaders of the House Financial Services Committee submitted a proposal entitled the Protecting American Taxpayers and Homeowners Act of 2013 (the “PATH Act”), which was approved by the committee on July 24, 2013. Both proposals would have direct implications for the FHLBanks if enacted.

43

While both proposals reflect the efforts over the past year to lay the groundwork for a new U.S. housing finance structure by creating a single securitization platform and establishing national standards for mortgage securitization, they differ on the role that the federal government would play in a revamped housing finance structure. The Housing Finance Reform Act would establish the Federal Mortgage Insurance Corporation (the “FMIC”) as an independent agency in the federal government, replacing the Finance Agency as the primary federal regulator of the FHLBanks. The FMIC would facilitate the securitization of eligible mortgages by insuring covered securities in a catastrophic risk position. The FHLBanks, or a newly created subsidiary, would be allowed to apply to become an approved issuer of covered securities to facilitate access to the secondary market for smaller community mortgage lenders. Any covered MBS issued by the FHLBanks or a subsidiary would not be issued as a consolidated obligation and would not be treated as a joint and several obligation of any FHLBank that did not elect to participate in such issuance.

By contrast, the PATH Act would effectively eliminate any government guarantee of conventional, conforming mortgages except for FHA, VA and similar loans designed to serve first-time homebuyers and low- and moderate-income borrowers. The FHLBanks would be authorized to act as aggregators of mortgages for securitization through a newly established common market utility.

The PATH Act would also revamp the statutory provisions governing the board composition of FHLBanks. Among other things, the number of directors would be capped at 15, which could be an important factor in the event that two FHLBanks elected to merge. Special provisions would govern mergers, capping the number of member directors allocated to a state at 2 until each state has at least 1 member director. In addition, the Finance Agency would be given the authority, consistent with the authority of other banking regulators, to regulate and examine vendors of a FHLBank. Further, the PATH Act would remove the requirement that the Finance Agency adopt regulations establishing standards of community investment or service for FHLBank members.

Any fundamental changes to the U.S. housing finance system could have adverse consequences for the FHLBanks and their ability to provide readily accessible liquidity to their members. However, it is not possible at this time to determine whether or when legislation would be enacted on housing GSE or housing finance reform. The ultimate effects of these efforts on the Bank and the agency debt markets are unknown and will depend on the content of legislation or other changes, if any, that ultimately are enacted.

Other Developments

Recommendations Regarding Money Market Mutual Fund Reform

On November 19, 2012, the Financial Stability Oversight Council (the “Oversight Council”) published for comment proposed recommendations for structural reforms of money market mutual funds (“MMFs”). In making these proposed recommendations, the Oversight Council stated that such reforms are intended to address the structural vulnerabilities of MMFs. In addition, on June 19, 2013 the SEC proposed two alternatives for amending the rules that govern MMFs under the Investment Company Act of 1940. The first alternative would require non-government institutional MMFs to sell and redeem shares based on the current market-based value of the securities in their underlying portfolios. The second alternative would require non-government MMFs to generally impose a liquidity fee if a fund's liquidity levels fell below a specified threshold and would also permit the funds to suspend redemptions temporarily. The demand for FHLBank System consolidated obligations could be impacted by the structural reforms that are ultimately adopted.

Basel Committee on Banking Supervision - Capital Framework

On July 2, 2013, the Federal Reserve Board and the Office of the Comptroller of the Currency adopted a final rule and the FDIC adopted an interim final rule establishing new minimum capital standards for financial institutions to implement the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision. The new capital framework includes, among other things:

• a new minimum ratio of common equity tier 1 capital to risk-weighted assets, a higher minimum ratio of tier 1 capital to risk-weighted assets and a common equity tier 1 capital conservation buffer;

• revised methodologies for calculation of risk-weighted assets to enhance risk sensitivity; and

• a minimum supplementary leverage ratio for financial institutions subject to the “advanced approaches” risk-based capital rules.

The new framework could require some member banks to divest assets in order to comply with the more stringent capital and liquidity requirements, thereby tending to decrease their need for the Bank's advances. The requirements may also adversely impact investor demand for FHLBank consolidated obligations to the extent that impacted institutions divest or limit their investments

44

in consolidated obligations. Conversely, the new requirements could incentivize members to use term advances to create and maintain balance sheet liquidity. Most member banks must begin to comply with the final rule by January 1, 2015, although some larger member banks must begin to comply by January 1, 2014.

Financial Condition

The following table provides selected period-end balances as of June 30, 2013 and December 31, 2012, as well as selected average balances for the six-month period ended June 30, 2013 and the year ended December 31, 2012. As shown in the table, the Bank’s total assets decreased by 8.6 percent (or $3.1 billion) between December 31, 2012 and June 30, 2013, due to declines of $2.5 billion and $0.5 billion in the Bank's short-term liquidity holdings and long-term investments, respectively. As the Bank’s assets decreased, the funding for those assets also decreased. During the six months ended June 30, 2013, total consolidated obligations decreased by $2.9 billion as consolidated obligation bonds decreased by $3.5 billion and consolidated obligation discount notes increased by $0.6 billion.

The activity in each of the major balance sheet captions is discussed in the sections following the table.

Advances

The Bank's advances balances (at par value) increased $128 million during the first six months of 2013, despite the repayment of $1.0 billion of advances by Comerica Bank, the Bank's second largest borrower as of June 30, 2013. The Bank's lending activities remained subdued during the period due largely to high deposit levels and weak demand for loans at member institutions. The following table presents advances outstanding, by type of institution, as of June 30, 2013 and December 31, 2012.

The Bank is required by statute and regulation to obtain sufficient collateral from members/borrowers to fully secure all advances and other extensions of credit. The Bank’s collateral arrangements with its members/borrowers and the types of collateral it accepts to secure advances are described in the 2012 10-K. To ensure the value of collateral pledged to the Bank is sufficient to secure its advances, the Bank applies various haircuts, or discounts, to determine the value of the collateral against which borrowers may borrow. From time to time, the Bank reevaluates the adequacy of its collateral haircuts under a range of stress scenarios to ensure that its collateral haircuts are sufficient to protect the Bank from credit losses on advances.

In addition, as described in the 2012 10-K, the Bank reviews the financial condition of its depository institution borrowers on at least a quarterly basis to identify any borrowers whose financial condition indicates they might pose an increased credit risk and, as needed, takes appropriate action. The Bank has not experienced any credit losses on advances since it was founded in 1932 and, based on its credit extension and collateral policies, management currently does not anticipate any credit losses on advances. Accordingly, the Bank has not provided any allowance for losses on advances.

Short-Term Liquidity Holdings

At June 30, 2013, the Bank’s short-term liquidity holdings were comprised of $1.5 billion of overnight federal funds sold to domestic bank counterparties, $1.8 billion of non-interest bearing excess cash balances held at the Federal Reserve Bank of Dallas and a $250 million overnight reverse repurchase agreement. All of the Bank's federal funds sold during the six months ended June 30, 2013 were transacted with domestic bank counterparties on an overnight basis. At December 31, 2012, the Bank’s short-term liquidity holdings were comprised of $2.2 billion of overnight federal funds sold to domestic bank counterparties, $0.9 billion of non-interest bearing excess cash balances held at the Federal Reserve Bank of Dallas and $3.0 billion of overnight reverse repurchase agreements. As of June 30, 2013, the Bank’s overnight federal funds sold consisted of $1.1 billion sold to counterparties rated single-A and $0.4 billion sold to counterparties rated triple-B. The credit ratings presented in the preceding sentence represent the lowest long-term rating assigned to the counterparty by Moody’s, S&P or Fitch Ratings, Ltd. (“Fitch”). The amount of the Bank’s short-term liquidity holdings fluctuates in response to several factors, including the anticipated demand for advances, the timing and extent of advance prepayments, changes in the Bank’s deposit balances, the Bank’s pre-funding activities, changes in the returns provided by short-term investment alternatives relative to the Bank’s discount note funding costs, and the level of liquidity needed to satisfy Finance Agency requirements. (For a discussion of the Finance Agency’s liquidity requirements, see the section below entitled “Liquidity and Capital Resources.”)

As of June 30, 2013, 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 and Fitch and AA+ by S&P. The Bank's holdings of other debentures were rated Aaa by Moody's and AA+ by S&P; the other debentures were not rated by Fitch.

48

During the six months ended June 30, 2013, the Bank acquired $658 million of GSE MBS, all of which were classified as held-to-maturity. The Bank did not sell any long-term investments during the six months ended June 30, 2013. During this same six-month period, the proceeds from maturities and paydowns of held-to-maturity securities totaled approximately $969 million.

The Bank is precluded by regulation from purchasing additional MBS if such purchase would cause the aggregate amortized cost of its MBS holdings to exceed 300 percent of the Bank’s total regulatory capital (the sum of its capital stock — putable, mandatorily redeemable capital stock and retained earnings). At June 30, 2013, the Bank held $4.9 billion (amortized cost) of MBS, which represented 277 percent of its total regulatory capital as of that date. In July 2013, the Bank purchased an additional $217 million of GSE MBS. The Bank intends to continue to purchase additional GSE MBS to the extent it has the regulatory capacity to do so.

While the Bank is permitted under applicable policies and regulations to purchase certain other types of highly rated long-term investments, it does not currently anticipate purchasing such securities in the foreseeable future.

Gross unrealized losses on the Bank’s MBS investments decreased from $35.4 million at December 31, 2012 to $24.3 million at June 30, 2013. As of June 30, 2013, $23.1 million (or 95 percent) of the gross unrealized losses related to the Bank’s holdings of non-agency RMBS.

The Bank evaluates outstanding held-to-maturity and available-for-sale investment securities in an unrealized loss position as of the end of each quarter for other-than-temporary impairment (“OTTI”). An investment security is impaired if the fair value of the investment is less than its amortized cost. For a summary of the Bank’s OTTI evaluation, see “Item 1. Financial Statements” (specifically, Notes 3 and 4 beginning on pages 7 and 9, respectively, of this report).

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 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 on its analysis of the securities in this portfolio, the Bank believes that the unrealized losses as of June 30, 2013 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.

All of the Bank’s non-agency RMBS are rated by one or more of the following NRSROs: Moody’s, S&P and/or Fitch. The following table presents the credit ratings assigned to the Bank’s non-agency RMBS holdings as of June 30, 2013. The credit ratings presented in the table represent the lowest rating assigned to the security by Moody’s, S&P or Fitch.

At June 30, 2013, the Bank’s portfolio of non-agency RMBS was comprised of 11 securities with an aggregate unpaid principal balance of $60 million that are backed by first lien fixed-rate loans and 19 securities with an aggregate unpaid principal balance of $173 million that are backed by first lien option adjustable-rate mortgage (“option ARM”) loans. In comparison, as of December 31, 2012, the 11 securities backed by fixed-rate loans had an aggregate unpaid principal balance of $73 million and the 19 securities backed by option ARM loans had an aggregate unpaid principal balance of $183 million. The following table provides a summary of the Bank’s non-agency RMBS as of June 30, 2013 by classification by the originator at the time of issuance, collateral type and year of securitization; the Bank does not hold any RMBS that were labeled as subprime by the originator at the time of issuance.

_____________________________

⁽¹⁾  Weighted average percentages are computed based upon unpaid principal balances.

⁽²⁾  Collateral delinquency reflects the percentage of the underlying loan balances that are 60 or more days past due, including loans in foreclosure and real estate owned; as of June 30, 2013, actual cumulative loan losses in the pools of loans underlying the Bank’s non-agency RMBS portfolio ranged from 0 percent to 11.77 percent.

⁽³⁾  Current credit enhancement percentages reflect the ability of subordinated classes of securities to absorb principal losses and interest shortfalls before the senior classes held by the Bank are impacted (i.e., the losses, expressed as a percentage of the outstanding principal balances, that could be incurred in the underlying loan pools before the securities held by the Bank would be impacted, assuming that all of those losses occurred on the measurement date). Depending upon the timing and amount of losses in the underlying loan pools, it is possible that the senior classes held by the Bank could bear losses in scenarios where the cumulative loan losses do not exceed the current credit enhancement percentage.

⁽⁴⁾  Minimum credit enhancement reflects the security in each vintage year with the lowest current credit enhancement.

⁽⁵⁾  Reflects the label assigned to the securities by the originator at the time of issuance.

The geographic concentration by state of the loans underlying the Bank’s non-agency RMBS as of December 31, 2012 is provided in the Bank’s 2012 10-K. There were no material changes in these concentrations during the six months ended June 30, 2013.

To assess whether the entire amortized cost bases of its non-agency RMBS are likely to be recovered, the Bank performed a cash flow analysis for each of its non-agency RMBS holdings as of June 30, 2013 under a base case (or best estimate) scenario. The procedures used in this analysis, together with the results thereof, are summarized in “Item 1. Financial Statements” (specifically, Note 4 beginning on page 9 of this report). A summary of the significant inputs that were used in the Bank’s analysis of its entire non-agency RMBS portfolio as of June 30, 2013 is set forth in the table below.

_____________________________

⁽¹⁾  The Bank’s non-agency RMBS holdings are classified as prime or Alt-A in the table above based upon the assumptions that were used to analyze the securities.

⁽²⁾  Prepayment rates reflect the weighted average of projected future voluntary prepayments. Default rates reflect the total balance of loans projected to default as a percentage of the current unpaid principal balance of each of the underlying loan pools. Loss severities reflect the total projected loan losses as a percentage of the total balance of loans that are projected to default.

In addition to evaluating its non-agency RMBS under a best estimate scenario, the Bank also performed a cash flow analysis for each of these securities as of June 30, 2013 under a more stressful housing price scenario. This more stressful scenario was based on a housing price forecast that assumed home price changes for the 12-month period beginning April 1, 2013 were 5 percentage points lower than the base case scenario followed by recovery rates which are 33 percent lower than those used in the base case scenario. Under the more stressful scenario, home prices for the vast majority of housing markets were projected to decline by 0 percent to 8 percent during the 12-month period beginning April 1, 2013.

Under the more stressful housing price scenario, one of the Bank’s non-agency RMBS would have been deemed to be other-than-temporarily impaired as of June 30, 2013 (as compared to no securities in the Bank’s best estimate scenario as of that date). The credit loss that would have been recorded in earnings during the quarter ended June 30, 2013 if the more stressful housing price scenario had been used in the Bank's OTTI assessment would have been $25,000.

While substantially all of the Bank's MBS portfolio is comprised of collateralized mortgage obligations ("CMOs") with floating rate coupons ($5.0 billion par value at June 30, 2013) that do not expose it to interest rate risk if interest rates rise moderately, these securities include caps that would limit increases in the floating rate coupons if short-term interest rates rise above the caps. In addition, if interest rates rise, prepayments on the mortgage loans underlying the securities would likely decline, thus lengthening the time that the securities would remain outstanding with their coupon rates capped. As of June 30, 2013, one-month LIBOR was 0.19 percent and the effective interest rate caps on one-month LIBOR (the interest cap rate minus the stated spread on the coupon) embedded in the CMO floaters ranged from 6.0 percent to 15.3 percent. The largest concentration of embedded effective caps ($4.4 billion) was between 6.0 percent and 7.0 percent. As of June 30, 2013, one-month LIBOR rates were approximately 581 basis points below the lowest effective interest rate cap embedded in the CMO floaters. To hedge a portion of the potential cap risk embedded in these securities, the Bank held $3.9 billion of interest rate caps with remaining maturities ranging from 7 months to 36 months as of June 30, 2013, and strike rates ranging from 6.00 percent to 7.00 percent. If interest rates rise above the strike rates specified in these interest rate cap agreements, the Bank will be entitled to receive interest payments according to the terms and conditions of such agreements. These payments would be based upon the notional amounts of those agreements and the difference between the specified strike rate and either one-month or three-month LIBOR.

The following table provides a summary of the notional amounts, strike rates and expiration periods of the Bank’s portfolio of stand-alone CMO-related interest rate cap agreements as of June 30, 2013.

Consolidated Obligations and Deposits

During the six months ended June 30, 2013, the Bank’s outstanding consolidated obligation bonds (at par value) decreased by $3.4 billion while its outstanding consolidated obligation discount notes increased by $0.6 billion. The following table presents the composition of the Bank’s outstanding bonds at June 30, 2013 and December 31, 2012.

The Bank’s funding needs remained relatively low during the first six months of 2013, with only $3.3 billion of consolidated obligation bonds issued during this period. The proceeds of these issuances were generally used to replace maturing or called consolidated obligations.

The average LIBOR cost of consolidated obligation bonds issued during the second quarter of 2013 was approximately equal to the average LIBOR cost of consolidated obligation bonds issued during the fourth quarter of 2012 and the first quarter of 2013. The weighted average cost of swapped and variable-rate consolidated obligation bonds issued by the Bank was approximately LIBOR minus 16 basis points during the quarter ended December 31, 2012 and approximately LIBOR minus 17 basis points in both the first and second quarters of 2013.

Demand and term deposits were $1.1 billion and $1.2 billion at June 30, 2013 and December 31, 2012, respectively. The size of the Bank’s deposit base varies as market factors change, including the attractiveness of the Bank’s deposit pricing relative to the rates available to members on alternative money market investments, members’ investment preferences with respect to the maturity of their investments, and member liquidity.

Capital

The Bank’s outstanding capital stock (excluding mandatorily redeemable capital stock) was $1.16 billion and $1.22 billion at June 30, 2013 and December 31, 2012, respectively. The Bank’s average outstanding capital stock (excluding mandatorily redeemable capital stock) decreased from $1.21 billion for the year ended December 31, 2012 to $1.11 billion for the six months ended June 30, 2013.

Mandatorily redeemable capital stock outstanding at June 30, 2013 and December 31, 2012 was $4.2 million and $4.5 million, respectively. Although mandatorily redeemable capital stock is excluded from capital (equity) for financial reporting purposes, it is considered capital for regulatory purposes.

At June 30, 2013 and December 31, 2012, the Bank’s five largest shareholders collectively held $223 million and $290 million, respectively, of capital stock, which represented 19.3 percent and 23.8 percent, respectively, of the Bank’s total outstanding capital stock (including mandatorily redeemable capital stock) as of those dates. The following table presents the Bank’s five largest shareholders as of June 30, 2013.

As of June 30, 2013, all of the stock held by the five institutions shown in the table above was classified as capital in the statement of condition.

Members are required to maintain an investment in Class B stock equal to the sum of a membership investment requirement and an activity-based investment requirement. Currently, the membership investment requirement is 0.04 percent of each member’s total assets as of the previous calendar year-end, subject to a minimum of $1,000 and a maximum of $7,000,000, and the activity-based investment requirement is 4.10 percent of outstanding advances.

Periodically, the Bank repurchases a portion of members’ excess capital stock. Excess stock is defined as the amount of stock held by a member (or former member) in excess of that institution’s minimum investment requirement. The portion of members’ excess capital stock subject to repurchase is known as surplus stock. The Bank generally repurchases surplus stock on the last business day of the month following the end of each calendar quarter. For the quarterly repurchases that occurred on January 31, 2013, April 30, 2013 and July 31, 2013, surplus stock was defined as the amount of stock held by a member in excess of 102.5 percent of the member’s minimum investment requirement. For the repurchases that occurred on those dates, a member’s surplus stock was not repurchased if the amount of that member’s surplus stock was $100,000 or less or if, subject to certain exceptions, the member was on restricted collateral status. From time to time, the Bank may modify the definition of surplus stock or the timing and/or frequency of surplus stock repurchases.

The following table sets forth the repurchases of surplus stock that have occurred since December 31, 2012.

During the six months ended June 30, 2013, the Bank’s retained earnings increased by $38.0 million, from $571.9 million to $609.9 million. During this same period, the Bank paid dividends on capital stock totaling $2.2 million, which represented an annualized dividend rate of 0.375 percent. The Bank’s first and second quarter 2013 dividend rates exceeded the upper end of the Federal Reserve’s target for the federal funds rate for the quarters ended December 31, 2012 and March 31, 2013, respectively, by 12.5 basis points. The first quarter dividend, applied to average capital stock held during the period from October 1, 2012 through December 31, 2012, was paid on March 29, 2013. The second quarter dividend, applied to average capital stock held during the period from January 1, 2013 through March 31, 2013, was paid on June 28, 2013.

The Bank has had a long-standing practice of benchmarking the dividend rate that it pays on capital stock to the average federal funds rate. Consistent with that practice, the Bank manages its balance sheet so that its returns (attributable to adjusted earnings) generally track short-term interest rates.

While there can be no assurances, taking into consideration its current earnings expectations and anticipated market conditions, the Bank currently expects to pay dividends for the remainder of 2013 at or slightly above the upper end of the Federal Reserve’s target range for the federal funds rate for the applicable dividend period (i.e., for each calendar quarter during this period, the upper end of the Federal Reserve's target range for the federal funds rate for the preceding quarter). Consistent with its long-standing practice, the Bank expects to pay these dividends in the form of capital stock with any fractional shares paid in cash.

The Bank is required to maintain at all times permanent capital (defined under the Finance Agency’s rules as retained earnings and amounts paid in for Class B stock, regardless of its classification as equity or liabilities for financial reporting purposes) in an amount at least equal to its risk-based capital requirement, which is the sum of its credit risk capital requirement, its market risk capital requirement, and its operations risk capital requirement, as further described in the Bank’s 2012 10-K. At June 30, 2013, the Bank’s total risk-based capital requirement was $516 million, comprised of credit risk, market risk and operations risk capital requirements of $229 million, $168 million and $119 million, respectively, and its permanent capital was $1.8 billion.

In addition to the risk-based capital requirement, the Bank is subject to two other capital requirements. First, the Bank must, at all times, maintain a minimum total capital-to-assets ratio of 4.0 percent. For this purpose, total capital is defined by Finance Agency rules and regulations as the Bank’s permanent capital and the amount of any general allowance for losses (i.e., those reserves that are not held against specific assets). Second, the Bank is required to maintain at all times a minimum leverage capital-to-assets ratio in an amount at least equal to 5.0 percent of its total assets. In applying this requirement to the Bank, leverage capital includes the Bank’s permanent capital multiplied by a factor of 1.5 plus the amount of any general allowance for losses. The Bank did not have any general allowance for losses at June 30, 2013 or December 31, 2012. Under the regulatory definitions, total capital and permanent capital exclude accumulated other comprehensive income (loss). At all times during the six months ended June 30, 2013, the Bank was in compliance with all of its regulatory capital requirements. At June 30, 2013, the Bank's total capital-to-assets and leverage capital-to-assets ratios were 5.42% and 8.13%, respectively. For a

54

summary of the Bank’s compliance with the Finance Agency’s capital requirements as of June 30, 2013 and December 31, 2012, see “Item 1. Financial Statements” (specifically, Note 11 on page 28 of this report).

Derivatives and Hedging Activities

The Bank enters into interest rate swap, swaption, cap and forward rate agreements (collectively, interest rate exchange agreements) to manage its exposure to changes in interest rates and/or to adjust the effective maturity, repricing index and/or frequency or option characteristics of financial instruments. This use of derivatives is integral to the Bank’s financial management strategy, and the impact of these interest rate exchange agreements permeates the Bank’s financial statements. For additional discussion, see “Item 1. Financial Statements” (specifically, Note 10 beginning on page 21 of this report). The following table provides the notional balances of the Bank’s derivative instruments, by balance sheet category and accounting designation, as of June 30, 2013 and December 31, 2012.

The Bank has transacted substantially all of its interest rate exchange agreements bilaterally with large financial institutions (with which it has in place master agreements). In doing so, the Bank has generally exchanged a defined market risk for the risk that the counterparty will not be able to fulfill its obligations in the future. The Bank manages this credit risk by spreading its transactions among as many highly rated counterparties as is practicable, by entering into master agreements with each of its non-member bilateral counterparties that include maximum unsecured credit exposure thresholds ranging from $100,000 to $500,000, and by monitoring its exposure to each counterparty on a daily basis. In addition, all of the Bank’s master agreements with its bilateral counterparties include netting arrangements whereby the fair values of all interest rate derivatives (including accrued interest receivables and payables) with each counterparty are offset for purposes of measuring credit exposure. The master agreements with the Bank's non-member bilateral counterparties require the delivery of collateral consisting of cash or very liquid, highly rated securities (generally consisting of U.S. government-guaranteed or agency debt securities) if credit risk exposures rise above the thresholds.

The notional amount of interest rate exchange agreements does not reflect the Bank’s credit risk exposure, which is much less than the notional amount. The Bank's net credit risk exposure is based on the current estimated cost, on a present value basis, of replacing at current market rates all interest rate exchange agreements with individual counterparties, if those counterparties were to default, after taking into account the value of any cash and/or securities collateral held or remitted by the Bank. For counterparties with which the Bank is in a net gain position, the Bank has credit exposure when the collateral it is holding (if any) has a value less than the amount of the gain. For counterparties with which the Bank is in a net loss position, the Bank has credit exposure when it has delivered collateral with a value greater than the amount of the loss position. As discussed above, the Bank’s master agreements with its non-member bilateral counterparties contain unsecured credit exposure thresholds that must be met before collateral is required to be delivered by one party to the other party. Once the counterparties agree to the valuations of the interest rate exchange agreements, and if it is determined that the unsecured credit exposure exceeds the

57

threshold, then, upon a request made by the unsecured counterparty, the party that has the unsecured obligation to the counterparty bearing the risk of the unsecured credit exposure generally must deliver sufficient collateral (or return a sufficient amount of previously remitted collateral) to reduce the unsecured credit exposure to zero (or, in the case of pledged securities, to an amount equal to the discount applied to the securities under the terms of the master agreement). Collateral is delivered (or returned) daily when these thresholds are met.

As a result of new statutory and regulatory requirements emanating from the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"), certain derivative transactions that the Bank enters into on and after June 10, 2013 are required to be cleared through a third-party central clearinghouse. Cleared trades are subject to initial and variation margin requirements established by the clearinghouse and its clearing members. While clearing derivatives through a central clearinghouse may or may not reduce the counterparty credit risk typically associated with bilateral transactions, certain features associated with cleared trades have the potential to make derivative transactions more costly than they have been historically for the Bank. As of June 30, 2013, the Bank had cleared trades with notional amounts totaling $55 million. The fair values of these derivatives and the associated initial and variation margin (i.e., cash collateral) were not material to the Bank at that date.

The following table provides information regarding the Bank’s derivative counterparty credit exposure as of June 30, 2013.

The Bank offers interest rate swaps, caps and floors to its members to assist them in meeting their risk management objectives. In derivative transactions with its members, the Bank acts as an intermediary by entering into an interest rate exchange agreement with the member and then entering into an offsetting interest rate exchange agreement with one of the Bank’s non-member derivative counterparties discussed above. When entering into interest rate exchange agreements with its members, the Bank requires the member to post eligible collateral in an amount equal to the sum of the net market value of the member’s derivative transactions with the Bank (if the value is positive to the Bank) plus a percentage of the notional amount of any interest rate swaps, with market values determined on at least a monthly basis. Eligible collateral for derivative transactions consists of collateral that is eligible to secure advances and other obligations under the member’s Advances and Security Agreement with the Bank.

The Dodd-Frank Act will also change the regulatory framework for derivative transactions that are not subject to mandatory clearing requirements (uncleared trades). While the Bank expects to be able in certain instances to continue to enter into uncleared trades on a bilateral basis, those transactions will be subject to new (but not yet finalized) regulatory requirements, including minimum margin and capital requirements imposed by regulators on one or both counterparties to the transactions. Any changes to the margin or capital requirements associated with uncleared trades could adversely affect the pricing of certain uncleared derivative transactions entered into by the Bank, thereby increasing the costs of managing the Bank’s interest rate risk. Because the Dodd-Frank Act calls for a number of regulations, orders, determinations and reports to be issued, the impact of this legislation on the Bank’s hedging activities and the costs associated with those activities will become known only after all of the required regulations, orders, determinations, and reports are issued and implemented. For further information regarding the Dodd-Frank Act, see the Bank’s 2012 10-K (specifically, “Business — Legislative and Regulatory Developments” beginning on page 16 of that report).

Market Value of Equity

The ratio of the Bank’s estimated market value of equity to its book value of equity was approximately 109 percent at both June 30, 2013 and December 31, 2012. For additional discussion, see “Part I / Item 3 — Quantitative and Qualitative Disclosures About Market Risk — Interest Rate Risk.”

Results of Operations

Net Income

Net income for the three months ended June 30, 2013 and 2012 was $22.1 million and $22.5 million, respectively. The Bank’s net income for the three months ended June 30, 2013 represented an annualized return on average capital stock (“ROCS”) of 8.07 percent, which was 795 basis points above the average effective federal funds rate for the quarter. In comparison, the Bank’s ROCS was 7.66 percent for the three months ended June 30, 2012, which exceeded the average effective federal funds rate for that quarter by 751 basis points. Net income for the six months ended June 30, 2013 and 2012 was $40.2 million and $46.8 million, respectively. The Bank’s net income for the six months ended June 30, 2013 represented an annualized ROCS of 7.29 percent, which was 716 basis points above the average effective federal funds rate for the period. In comparison, the Bank’s ROCS was 7.81 percent percent for the six months ended June 30, 2012, which exceeded the average effective federal funds rate for that period by 768 basis points. To derive the Bank’s ROCS, net income is divided by average capital stock outstanding excluding stock that is classified as mandatorily redeemable capital stock. The factors contributing to the changes in ROCS compared to the average effective federal funds rate are discussed below.

Income Before Assessments

During the three months ended June 30, 2013 and 2012, the Bank’s income before assessments was $24.5 million and $25.0 million, respectively. As discussed in more detail below, the $0.5 million decrease in income before assessments from period to period was attributable to a $4.1 million decrease in net interest income, offset by a $2.2 million increase in other income and a $1.4 million decrease in other expense. The increase in other income was due primarily to a $3.1 million favorable change in net gains (losses) on derivatives and hedging activities and a $0.1 million decrease in credit charges on the Bank's non-agency RMBS holdings, offset by a $1.2 million decrease in gains on optional advance commitments carried at fair value.

During the six months ended June 30, 2013 and 2012, the Bank’s income before assessments was $44.7 million and $52.0 million, respectively. As discussed in more detail below, the $7.3 million decrease in income before assessments from period to period was attributable to a $9.9 million decrease in net interest income, offset by a $1.9 million decrease in other expense and a $0.7 million increase in other income. The increase in other income was due primarily to a $2.3 million increase in net gains on derivatives and hedging activities and a $0.4 million decrease in credit charges on the Bank's non-agency RMBS holdings, offset by a $2.4 million decrease in gains on optional advance commitments carried at fair value.

The components of income before assessments (net interest income, other income/loss and other expense) are discussed in more detail in the following sections.

59

Net Interest Income

For the three months ended June 30, 2013 and 2012, the Bank’s net interest income was $36.5 million and $40.6 million, respectively. The Bank’s net interest income was $71.3 million and $81.2 million for the six months ended June 30, 2013 and 2012, respectively. As described further below, the Bank’s net interest income does not include net interest settlements on economic hedge derivatives, which also contributed to the Bank’s overall income before assessments during the three and six months ended June 30, 2013 and 2012. If these net interest settlements had been included, net interest income would have decreased by $6.0 million and $13.5 million for the three and six months ended June 30, 2013, respectively, as compared to the corresponding periods in 2012. The decreases in net interest income were due in large part to decreases in the average balances of interest-earning assets in both the three and six months ended June 30, 2013, as compared to the corresponding periods in 2012, as well as a decrease in the net interest margin for the six-month period.

For the three months ended June 30, 2013 and 2012, the Bank’s net interest margin was 45 basis points and 46 basis points, respectively. The Bank’s net interest margin was 43 basis points and 47 basis points for the six months ended June 30, 2013 and 2012, respectively. Net interest margin, or net interest income as a percentage of average earning assets, is a function of net interest spread and the rates of return on assets funded by the investment of the Bank’s capital. Net interest spread is the difference between the yield on interest-earning assets and the cost of interest-bearing liabilities. The Bank’s net interest spread was 42 basis points for both the three months ended June 30, 2013 and 2012. The Bank’s net interest spread decreased from 42 basis points for the six months ended June 30, 2012 to 40 basis points for the six months ended June 30, 2013. The contribution of earnings from the Bank’s invested capital to the net interest margin (the impact of non-interest bearing funds) decreased from 4 basis points for the three months ended June 30, 2012 to 3 basis points for the three months ended June 30, 2013. The contribution of earnings from the Bank’s invested capital to the net interest margin decreased from 5 basis points for the six months ended June 30, 2012 to 3 basis points for the six months ended June 30, 2013, due to a decrease in short-term interest rates.

As noted above, the Bank’s net interest income excludes net interest settlements on economic hedge derivatives. During the six months ended June 30, 2013, the Bank used $4.5 billion (average notional balance) of interest rate basis swaps to hedge the risk of changes in spreads between one-month and three-month LIBOR and approximately $0.5 billion (average notional balance) of interest rate swaps to convert variable-rate consolidated obligations from the daily effective federal funds rate to three-month LIBOR (“federal funds floater swaps”). During the comparable period in 2012, the Bank used $4.7 billion (average notional balance) of interest rate basis swaps to hedge the risk of changes in spreads between one-month and three-month LIBOR, approximately $1.9 billion (average notional balance) of fixed-for-floating interest rate swaps to hedge some of its longer-term discount notes and approximately $0.7 billion (average notional balance) of federal funds floater swaps to convert variable-rate consolidated obligations from the daily effective federal funds rate to three-month LIBOR. These swaps are accounted for as economic hedges. Net interest income associated with economic hedge derivatives is recorded in other income (loss) in the statements of income and therefore excluded from net interest income, net interest margin and net interest spread. Net interest income on the Bank’s economic hedge derivatives totaled $0.9 million and $2.3 million for the three and six months ended June 30, 2013, respectively, compared to $2.9 million and $5.9 million, respectively, for the corresponding periods in 2012.

The following table presents average balance sheet amounts together with the total dollar amounts of interest income and expense and the weighted average interest rates of major earning asset categories and the funding sources for those earning assets for the three months ended June 30, 2013 and 2012.

Economic Hedge Derivatives

The Bank has issued a number of consolidated obligation bonds that are indexed to the daily effective federal funds rate. The Bank uses federal funds floater swaps to convert its interest payments with respect to these bonds from the daily effective federal funds rate to three-month LIBOR. As of June 30, 2013, the Bank’s federal funds floater swaps had an aggregate notional amount of $0.4 billion. As economic hedge derivatives, the changes in the fair values of the federal funds floater swaps are recorded in earnings with no offsetting changes in the fair values of the hedged items (i.e., the consolidated obligation federal funds floater bonds) and therefore can be a source of volatility in the Bank’s earnings. The fair values of federal funds floater swaps generally fluctuate based on the timing of the interest rate reset dates, the relationship between the effective federal funds rate and three-month LIBOR at the time of measurement, the projected relationship between the federal funds rate and three-month LIBOR for the remaining term of the interest rate swap, the projected OIS rates over the remaining term of the interest rate swap and the relationship between the current coupons for the interest rate swap and the prevailing market rates at the valuation date. At June 30, 2013, the carrying values of the Bank’s federal funds floater swaps totaled $0.2 million, excluding net accrued interest receivable.

From time to time, the Bank hedges some of its longer-term consolidated obligation discount notes using fixed-for-floating interest rate swaps. As stand-alone derivatives, the changes in the fair values of the Bank’s discount note swaps are recorded in earnings with no offsetting changes in the fair values of the hedged items (i.e., the consolidated obligation discount notes) and therefore can also be a source of volatility in the Bank’s earnings. The Bank did not have any discount note swaps outstanding as of June 30, 2013.

From time to time, the Bank also enters into interest rate basis swaps to reduce its exposure to changing spreads between one-month and three-month LIBOR. Under these agreements, the Bank generally receives three-month LIBOR and pays one-month LIBOR. As of June 30, 2013, the Bank was a party to 5 interest rate basis swaps with an aggregate notional amount of $3.7 billion. The Bank accounts for interest rate basis swaps as stand-alone derivatives and, as such, the fair value changes associated with these instruments can be a source of considerable volatility in the Bank’s earnings, particularly when one-month and/or three-month LIBOR, or the spreads between these two indices, are or are projected to be volatile. The fair values of one-month LIBOR to three-month LIBOR basis swaps generally fluctuate based on the timing of the interest rate reset dates, the relationship between one-month LIBOR and three-month LIBOR at the time of measurement, the projected relationship between one-month LIBOR and three-month LIBOR for the remaining term of the interest rate basis swap, the projected OIS rates over the remaining term of the interest rate basis swap and the relationship between the current coupons for the interest rate swap and the prevailing LIBOR rates at the valuation date. At June 30, 2013, the carrying values of the Bank’s stand-alone interest rate basis swaps totaled $12.9 million, excluding net accrued interest receivable. There were no sales of interest rate basis swaps during the six months ended June 30, 2013 or 2012. One interest rate basis swap with a notional amount of $1 billion matured during the three months ended June 30, 2013.

If the Bank holds its federal funds floater swaps and interest rate basis swaps to maturity, the cumulative life-to-date net unrealized gains associated with these instruments aggregating $13.1 million will ultimately reverse in future periods in the form of unrealized losses as the estimated fair values of these instruments decline to zero. The timing of this reversal will depend upon a number of factors including, but not limited to, the then-current and projected level and volatility of short-term interest rates over the lives of the derivatives. Occasionally, in response to changing balance sheet and market conditions, the Bank may terminate one or more interest rate basis swaps (or portions thereof) prior to their scheduled maturity. The Bank typically holds its federal funds floater swaps to maturity.

As discussed previously in the section entitled “Financial Condition — Long-Term Investments,” to hedge a portion of the risk associated with a significant increase in short-term interest rates, the Bank held (as of June 30, 2013) 16 interest rate cap agreements having a total notional amount of $3.9 billion. The premiums paid for these caps totaled $38.6 million. The fair values of interest rate cap agreements are dependent upon the level of interest rates, volatilities and remaining term to maturity. In general (assuming constant volatilities and no erosion in value attributable to the passage of time), interest rate caps will increase in value as market interest rates rise and will diminish in value as market interest rates decline. The value of interest rate caps will increase as volatilities increase and will decline as volatilities decrease. Absent changes in volatilities or interest rates, the value of interest rate caps will decline with the passage of time. As stand-alone derivatives, the changes in the fair values of the Bank’s interest rate cap agreements are recorded in earnings with no offsetting changes in the fair values of the hedged CMO LIBOR floaters with embedded caps and therefore can also be a source of considerable volatility in the Bank’s earnings.

At June 30, 2013, the carrying values of the Bank’s stand-alone interest rate cap agreements totaled $0.4 million. If the Bank holds these agreements to maturity, the values of the caps will ultimately decline to zero and be recorded as losses in net gains (losses) on derivatives and hedging activities in future periods.

Hedge Ineffectiveness

The Bank uses interest rate swaps to hedge the risk of changes in the fair value of some of its advances and consolidated obligation bonds and substantially all of its available-for-sale securities. These hedging relationships are designated as fair value hedges. To the extent these relationships qualify for hedge accounting, changes in the fair values of both the derivative (the interest rate swap) and the hedged item (limited to changes attributable to the hedged risk) are recorded in earnings. For those relationships that qualified for hedge accounting, the differences between the change in fair value of the hedged items and the change in fair value of the associated interest rate swaps (representing hedge ineffectiveness) were net gains (losses) of $1.5 million and $(1.7) million for the three months ended June 30, 2013 and 2012, respectively, and $2.2 million and $(2.4) million for the six months ended June 30, 2013 and 2012, respectively. To the extent these hedging relationships do not qualify for hedge accounting, or cease to qualify because they are determined to be ineffective, only the change in fair value of the derivative is recorded in earnings (in this case, there is no offsetting change in fair value of the hedged item). During the three months ended June 30, 2013 and 2012, the net gains relating to derivatives associated with specific advances that were not in qualifying hedging relationships were $46,000 and $14,000, respectively. The net gains relating to these derivatives totaled $51,000 and $48,000 for the six months ended June 30, 2013 and 2012, respectively.

Other

For a discussion of the other-than-temporary impairment losses on the Bank’s held-to-maturity securities, see “Item 1. Financial Statements” (specifically, Note 4 beginning on page 9 of this report).

As of December 31, 2012, the Bank had entered into optional advance commitments with a par value totaling $50 million, excluding commitments to fund Community Investment Program and Economic Development Program advances. Under each of these commitments, the Bank sold an option to a member that provided the member with the right to enter into an advance at a specified fixed rate and term on a specified future date, provided the member had satisfied all of the customary requirements for that advance. The Bank hedged these commitments through the use of interest rate swaptions, which were treated as economic hedges. The Bank irrevocably elected to carry these optional advance commitments at fair value under the fair value option. These optional advance commitments and the associated swaptions expired during the first quarter of 2013.

Other Expense

Total other expense, which includes the Bank’s compensation and benefits, other operating expenses and its proportionate share of the costs of operating the Finance Agency and the Office of Finance, totaled $16.8 million and $35.4 million for the three and six months ended June 30, 2013, compared to $18.2 million and $37.3 million for the corresponding periods in 2012.

Compensation and benefits were $9.1 million and $20.1 million for the three and six months ended June 30, 2013, compared to $9.9 million and $21.4 million for the corresponding periods in 2012. The decreases of $0.8 million and $1.3 million were due primarily to a decrease in the costs associated with the Bank’s participation in the Pentegra Defined Benefit Plan for Financial Institutions. The costs decreased as a result of the pension provisions contained in the Moving Ahead for Progress in the 21^st Century Act, which was signed into law by the President of the United States on July 6, 2012.

Other operating expenses for the three and six months ended June 30, 2013 were $6.7 million and $12.9 million, respectively, compared to $7.2 million and $13.5 million for the corresponding periods in 2012. The decreases of $0.5 million and $0.6 million, respectively, were attributable to fluctuations in several of the Bank’s other operating expenses, none of which were individually significant.

The Bank, together with the other FHLBanks, is assessed for the cost of operating the Finance Agency and the Office of Finance. The Bank’s share of these expenses totaled $1.0 million and $2.4 million for the three and six months ended June 30, 2013, respectively, compared to $1.1 million and $2.5 million for the corresponding periods in 2012.

AHP Assessments

While the Bank is exempt from all federal, state and local income taxes, it is obligated to set aside amounts for its Affordable Housing Program (“AHP”).

As required by statute, each year the Bank contributes 10 percent of its earnings (as adjusted for interest expense on mandatorily redeemable capital stock) to its AHP. The AHP provides grants that members can use to support affordable housing projects in their communities. Generally, the Bank’s AHP assessment is derived by adding interest expense on mandatorily redeemable capital stock to income before assessments; the result of this calculation is then multiplied by 10 percent. The Bank’s AHP assessments totaled $2.5 million for both the three months ended June 30, 2013 and 2012. The Bank's AHP assessments totaled $4.5 million and $5.2 million for the six months ended June 30, 2013 and 2012, respectively.

Critical Accounting Policies and Estimates

A discussion of the Bank’s critical accounting policies and the extent to which management uses judgment and estimates in applying those policies is provided in the Bank’s 2012 10-K. There were no substantial changes to the Bank’s critical accounting policies, or the extent to which management uses judgment and estimates in applying those policies, during the six months ended June 30, 2013.

The Bank evaluates its non-agency RMBS holdings for other-than-temporary impairment on a quarterly basis. The procedures used in this analysis, together with the results thereof as of June 30, 2013, are summarized in “Item 1. Financial Statements” (specifically, Note 4 beginning on page 9 of this report). In addition to evaluating its non-agency RMBS holdings under a base case (or best estimate) scenario, a cash flow analysis was also performed for each of these securities under a more stressful housing price scenario to determine the amount of credit losses that would have been recorded in earnings during the quarter ended June 30, 2013 if the more stressful housing price scenario had been used in the Bank's OTTI assessment as of June 30, 2013. The results of that more stressful analysis are presented on page 51 of this report.

Liquidity and Capital Resources

In order to meet members’ credit needs and the Bank’s financial obligations, the Bank maintains a portfolio of money market instruments typically consisting of overnight federal funds issued by highly rated domestic banks and overnight reverse repurchase agreements. From time to time, the Bank may also invest in short-term commercial paper and U.S. Treasury Bills. Beyond those amounts that are required to meet members’ credit needs and its own obligations, the Bank typically holds additional balances of short-term investments that fluctuate as the Bank invests the proceeds of debt issued to replace maturing and called liabilities, as the balance of deposits changes, as the returns provided by short-term investments vary relative to the costs of the Bank’s discount notes, and as the level of liquidity needed to satisfy Finance Agency requirements changes. At June 30, 2013, the Bank’s short-term liquidity portfolio was comprised of $1.5 billion of overnight federal funds sold to domestic bank counterparties, $1.8 billion of non-interest bearing excess cash balances held at the Federal Reserve Bank of Dallas and a $250.0 million overnight reverse repurchase agreement.

The Bank’s primary source of funds is the proceeds it receives from the issuance of consolidated obligation bonds and discount notes in the capital markets. Historically, the FHLBanks have issued debt throughout the business day in the form of discount notes and bonds with a wide variety of maturities and structures. Generally, the Bank has access to this market as needed during the business day to acquire funds to meet its needs.

In addition to the liquidity provided from the proceeds of the issuance of consolidated obligations, the Bank also maintains access to wholesale funding sources such as federal funds purchased and securities sold under agreements to repurchase (e.g., borrowings secured by its investments in MBS and/or agency debentures). Furthermore, the Bank has access to borrowings (typically short-term) from the other FHLBanks.

The 12 FHLBanks and the Office of Finance are parties to the Federal Home Loan Banks P&I Funding and Contingency Plan Agreement (the “Contingency Agreement”). The Contingency Agreement and related procedures are designed to facilitate the timely funding of principal and interest payments on FHLBank System consolidated obligations in the event that a FHLBank is not able to meet its funding obligations in a timely manner. The Contingency Agreement and related procedures provide for the issuance of overnight consolidated obligations ("Plan COs") directly to one or more FHLBanks that provide funds to avoid a shortfall in the timely payment of principal and interest on any consolidated obligations for which another FHLBank is the primary obligor. The direct placement by a FHLBank of consolidated obligations with another FHLBank is permitted only in those instances when direct placement of consolidated obligations is necessary to ensure that sufficient funds are available to timely pay all principal and interest on FHLBank System consolidated obligations due on a particular day. Through the date of this report, no Plan COs have ever been issued pursuant to the terms of the Contingency Agreement.

On occasion, and as an alternative to issuing new debt, the Bank may assume the outstanding consolidated obligations for which other FHLBanks are the original primary obligors. This occurs in cases where the original primary obligor may have participated in a large consolidated obligation issue to an extent that exceeded its immediate funding needs in order to facilitate better market execution for the issue. The original primary obligor might then warehouse the funds until they were needed, or make the funds available to other FHLBanks. Transfers may also occur when the original primary obligor’s funding needs change, and that FHLBank offers to transfer debt that is no longer needed to other FHLBanks. Transferred debt is typically fixed-rate, fixed-term, non-callable debt, and may be in the form of discount notes or bonds.

The Bank participates in such transfers of funding from other FHLBanks when the transfer represents favorable pricing relative to a new issue of consolidated obligations with similar features. The Bank did not assume any consolidated obligations from other FHLBanks during the six months ended June 30, 2013 or 2012.

68

The Bank manages its liquidity to ensure that, at a minimum, it has sufficient funds to meet operational and contingent liquidity requirements. When measuring its liquidity for these purposes, the Bank includes only contractual cash flows and the amount of funds it estimates would be available in the event the Bank were to use securities held in its long-term investment portfolio as collateral for repurchase agreements. While it believes purchased federal funds might be available as a source of funds, it does not include this potential source of funds in its calculations of available liquidity.

The Bank’s operational liquidity requirement stipulates that it have sufficient funds to meet its obligations due on any given day plus an amount equal to the statistically estimated (at the 99-percent confidence level) cash and credit needs of its members and associates for one business day without accessing the capital markets for the sale of consolidated obligations. As of June 30, 2013, the Bank’s estimated operational liquidity requirement was $1.5 billion. At that date, the Bank estimated that its operational liquidity exceeded this requirement by approximately $9.8 billion.

The Bank’s contingent liquidity requirement further requires that it maintain adequate balance sheet liquidity and access to other funding sources should it be unable to issue consolidated obligations for five business days. The combination of funds available from these sources must be sufficient for the Bank to meet its obligations as they come due and the cash and credit needs of its members, with the potential needs of members statistically estimated at the 99-percent confidence level. As of June 30, 2013, the Bank’s estimated contingent liquidity requirement was $3.1 billion. At that date, the Bank estimated that its contingent liquidity exceeded this requirement by approximately $8.2 billion.

In addition to the liquidity measures described above, the Bank is required, pursuant to guidance issued by the Finance Agency, to meet two daily liquidity standards, each of which assumes that the Bank is unable to access the market for consolidated obligations during a prescribed period. The first standard requires the Bank to maintain sufficient funds to meet its obligations for 15 days under a scenario in which it is assumed that members do not renew any maturing, prepaid or called advances. The second standard requires the Bank to maintain sufficient funds to meet its obligations for 5 days under a scenario in which it is assumed that members renew all maturing and called advances, with certain exceptions for very large, highly rated members. These requirements are more stringent than the 5-day contingent liquidity requirement discussed above. The Bank was in compliance with both of these liquidity requirements at all times during the six months ended June 30, 2013.

The Bank’s access to the capital markets has never been interrupted to an extent that the Bank’s ability to meet its obligations was compromised and the Bank does not currently believe that its ability to issue consolidated obligations will be impeded to that extent in the future. If, however, the Bank were unable to issue consolidated obligations for an extended period of time, the Bank would eventually exhaust the availability of purchased federal funds (including borrowings from other FHLBanks) and repurchase agreements as sources of funds. It is also possible that an event (such as a natural disaster) that might impede the Bank’s ability to raise funds by issuing consolidated obligations would also limit the Bank’s ability to access the markets for federal funds purchased and/or repurchase agreements.

Under those circumstances, to the extent that the balance of principal and interest that came due on the Bank’s debt obligations and the funds needed to pay its operating expenses exceeded the cash inflows from its interest-earning assets and proceeds from maturing assets, and if access to the market for consolidated obligations was not again available, the Bank would seek to access funding under the Contingency Agreement to repay any principal and interest due on its consolidated obligations. However, if the Bank were unable to raise funds by issuing consolidated obligations, it is likely that the other FHLBanks would have similar difficulties issuing debt. If funds were not available under the Contingency Agreement, the Bank’s ability to conduct its operations would be compromised even earlier than if this funding source was available.

A summary of the Bank’s contractual cash obligations and off-balance-sheet lending-related financial commitments by due date or remaining maturity as of December 31, 2012 is provided in the Bank’s 2012 10-K. There have been no material changes in the Bank’s contractual obligations outside the normal course of business during the six months ended June 30, 2013.

Recently Issued Accounting Guidance

For a discussion of recently issued accounting guidance, see “Item 1. Financial Statements” (specifically, Note 2 beginning on page 6 of this report).

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following quantitative and qualitative disclosures about market risk should be read in conjunction with the quantitative and qualitative disclosures about market risk that are included in the Bank’s 2012 10-K. The information provided herein is intended to update the disclosures made in the Bank’s 2012 10-K.

As a financial intermediary, the Bank is subject to interest rate risk. Changes in the level of interest rates, the slope of the interest rate yield curve, and/or the relationships (or spreads) between interest yields for different instruments have an impact on the Bank’s estimated market value of equity and its net earnings. This risk arises from a variety of instruments that the Bank enters into on a regular basis in the normal course of its business.

69

The terms of member advances, investment securities, and consolidated obligations may present interest rate risk and/or embedded option risk. As discussed in Management’s Discussion and Analysis of Financial Condition and Results of Operations, the Bank makes extensive use of interest rate derivative instruments, primarily interest rate swaps and caps, to manage the risk arising from these sources.

The Bank has investments in residential mortgage-related assets, primarily CMOs and, to a much smaller extent, MPF mortgage loans, both of which present prepayment risk. This risk arises from the mortgagors’ option to prepay their mortgages, making the effective maturities of these mortgage-based assets relatively more sensitive to changes in interest rates and other factors that affect the mortgagors’ decisions to repay their mortgages as compared to other long-term investment securities that do not have prepayment features. A decline in interest rates generally accelerates mortgage refinancing activity, thus increasing prepayments and thereby shortening the effective maturity of the mortgage-related assets. Conversely, rising rates generally slow prepayment activity and lengthen a mortgage-related asset’s effective maturity.

Historically, the Bank has managed the potential prepayment risk embedded in mortgage assets by purchasing almost exclusively floating rate securities, by purchasing highly structured tranches of mortgage securities that substantially limit the effects of prepayment risk, and/or by using interest rate derivative instruments to offset prepayment risk specific both to particular securities and to the overall mortgage portfolio. Because the Bank generally purchases MBS with the intent and expectation of holding them to maturity, the Bank’s risk management activities related to these securities are focused on those interest rate factors that pose a risk to the Bank’s future earnings. As the prices for some of the Bank's non-agency RMBS holdings indicate, these interest rate related factors may not necessarily be the same factors that are driving the market prices of the securities.

The Bank’s Risk Management Policy provides a risk management framework for the financial management of the Bank consistent with the strategic principles outlined in its Strategic Business Plan. The Bank develops its funding and hedging strategies to manage its interest rate risk within the risk limits established in its Risk Management Policy.

The Risk Management Policy articulates the Bank’s tolerance for the amount of overall interest rate risk the Bank will assume by limiting the maximum estimated loss in market value of equity that the Bank would incur under simulated 200 basis point changes in interest rates to 15 percent of the estimated base case market value. As reflected in the table below, the Bank was in compliance with this limit at each month end during the six months ended June 30, 2013.

As part of its ongoing risk management process, the Bank calculates an estimated market value of equity for a base case interest rate scenario and for interest rate scenarios that reflect parallel interest rate shocks. These calculations are made primarily for the purpose of analyzing and managing the Bank’s interest rate risk and, accordingly, have been designed for that purpose rather than for purposes of fair value disclosure under U.S. GAAP, which is determined as described in Note 13 beginning on page 28 of this report. The base case market value of equity is calculated by determining the estimated fair value of each instrument on the Bank’s balance sheet, and subtracting the estimated aggregate fair value of the Bank’s liabilities from the estimated aggregate fair value of the Bank’s assets. For purposes of these calculations, mandatorily redeemable capital stock is treated as equity rather than as a liability. The fair values of the Bank’s financial instruments (both assets and liabilities) are determined using vendor prices, dealer estimates or a pricing model. These calculations include values for MBS based on current estimated market prices, some of which reflect discounts that the Bank believes are largely related to credit concerns and a lack of market liquidity rather than the level of interest rates. For those instruments for which a pricing model is used, the calculations are based upon parameters derived from market conditions existing at the time of measurement, and are generally determined by discounting estimated future cash flows at the replacement (or similar) rate for new instruments of the same type with the same or very similar characteristics. The market value of equity calculations include non-financial assets and liabilities, such as premises and equipment, other assets, payables for AHP, and other liabilities at their recorded carrying amounts.

For purposes of compliance with the Bank’s Risk Management Policy limit on estimated losses in market value, market value of equity losses are defined as the estimated net sensitivity of the value of the Bank’s equity (the net value of its portfolio of assets, liabilities and interest rate derivatives) to 200 basis point parallel shifts in interest rates. The following table provides the Bank’s estimated base case market value of equity and its estimated market value of equity under up and down 200 basis point interest rate shock scenarios (and, for comparative purposes, its estimated market value of equity under up and down 100 basis point interest rate shock scenarios) for each month-end during the period from December 2012 through June2013. In addition, the table provides the percentage change in estimated market value of equity under each of these shock scenarios for the indicated periods.

⁽¹⁾  In the up 100 and up 200 basis point scenarios, the estimated market value of equity is calculated under assumed instantaneous +100 and +200 basis point parallel shifts in interest rates.

⁽²⁾  Pursuant to guidance issued by the Finance Agency, the estimated market value of equity is calculated under assumed instantaneous -100 and -200 basis point parallel shifts in interest rates, subject to a floor of 0.35 percent.

A related measure of interest rate risk is duration of equity. Duration is the weighted average maturity (typically measured in months or years) of an instrument’s cash flows, weighted by the present value of those cash flows. As such, duration provides an estimate of an instrument’s sensitivity to small changes in market interest rates. The duration of assets is generally expressed as a positive figure, while the duration of liabilities is generally expressed as a negative number. The change in value of a specific instrument for given changes in interest rates will generally vary in inverse proportion to the instrument’s duration. As market interest rates decline, instruments with a positive duration are expected to increase in value, while instruments with a negative duration are expected to decrease in value. Conversely, as interest rates rise, instruments with a positive duration are expected to decline in value, while instruments with a negative duration are expected to increase in value.

The values of instruments having relatively longer (or higher) durations are more sensitive to a given interest rate movement than instruments having shorter durations; that is, risk increases as the absolute value of duration lengthens. For instance, the value of an instrument with a duration of three years will theoretically change by three percent for every one percentage point (100 basis point) change in interest rates, while the value of an instrument with a duration of five years will theoretically change by five percent for every one percentage point change in interest rates.

The duration of individual instruments may be easily combined to determine the duration of a portfolio of assets or liabilities by calculating a weighted average duration of the instruments in the portfolio. These combinations provide a single straightforward metric that describes the portfolio’s sensitivity to interest rate movements. These additive properties can be applied to the assets and liabilities on the Bank’s statement of condition. The difference between the combined durations of the Bank’s assets and the combined durations of its liabilities is sometimes referred to as duration gap and provides a measure of the relative interest rate sensitivities of the Bank’s assets and liabilities.

Duration gap is a useful measure of interest rate sensitivity but does not account for the effect of leverage, or the effect of the absolute duration of the Bank’s assets and liabilities, on the sensitivity of its estimated market value of equity to changes in interest rates. The inclusion of these factors results in a measure of the sensitivity of the value of the Bank’s equity to changes in market interest rates referred to as the duration of equity. Duration of equity is the market value weighted duration of assets minus the market value weighted duration of liabilities divided by the market value of equity.

The significance of an entity’s duration of equity is that it can be used to describe the sensitivity of the entity’s market value of equity to movements in interest rates. A duration of equity equal to zero would mean, within a narrow range of interest rate movements, that the Bank had neutralized the impact of changes in interest rates on the market value of its equity.

A positive duration of equity would mean, within a narrow range of interest rate movements, that for each one year of duration the estimated market value of the Bank’s equity would be expected to decline by about 0.01 percent for every positive 0.01 percent change in the level of interest rates. A positive duration generally indicates that the value of the Bank’s assets is

71

more sensitive to changes in interest rates than the value of its liabilities (i.e., that the duration of its assets is greater than the duration of its liabilities).

Conversely, a negative duration of equity would mean, within a narrow range of interest rate movements, that for each one year of negative duration the estimated market value of the Bank’s equity would be expected to increase by about 0.01 percent for every positive 0.01 percent change in the level of interest rates. A negative duration generally indicates that the value of the Bank’s liabilities is more sensitive to changes in interest rates than the value of its assets (i.e., that the duration of its liabilities is greater than the duration of its assets).

The following table provides information regarding the Bank’s base case duration of equity as well as its duration of equity in up and down 100 and 200 basis point interest rate shock scenarios for each month-end during the period from December 2012 through June2013.

⁽¹⁾  In the up 100 and up 200 scenarios, the duration of equity is calculated under assumed instantaneous +100 and +200 basis point parallel shifts in interest rates.

⁽²⁾  Pursuant to guidance issued by the Finance Agency, the duration of equity was calculated under assumed instantaneous -100 and -200 basis point parallel shifts in interest rates, subject to a floor of 0.35 percent.

Duration of equity measures the impact of a parallel shift in interest rates on an entity’s market value of equity but may not be a good metric for measuring changes in value related to non-parallel rate shifts. An alternative measure for that purpose uses key rate durations, which measure portfolio sensitivity to changes in interest rates at particular points on a yield curve. Key rate duration is a specialized form of duration. It is calculated by estimating the change in value due to changing the market rate for one specific maturity point on the yield curve while holding all other variables constant. The sum of the key rate durations across an applicable yield curve is approximately equal to the overall portfolio duration.

The duration of equity measure represents the expected percentage change in the Bank’s market value of equity for a one percentage point (100 basis point) parallel change in interest rates. The key rate duration measure represents the expected percentage change in the Bank’s market value of equity for a one percentage point (100 basis point) parallel change in interest rates for a given maturity point on the yield curve, holding all other rates constant. The Bank has established a key rate duration limit of 7.5 years, measured as the difference between the maximum and minimum key rate durations calculated for nine defined individual maturity points on the yield curve. The Bank calculates these metrics monthly and was in compliance with these policy limits at each month-end during the first six months of 2013.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Bank’s management, under the supervision and with the participation of its Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of the Bank’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based upon that evaluation, the Bank’s Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, the Bank’s disclosure controls and procedures were effective in: (1) recording, processing, summarizing and reporting information required to be disclosed by the Bank in the reports that it files or submits under the Exchange Act within the time periods specified in the SEC’s rules and forms and (2) ensuring that information required to be disclosed by the Bank in the reports that it files or submits under the Exchange Act

72

is accumulated and communicated to the Bank’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures.

Changes in Internal Control Over Financial Reporting

There were no changes in the Bank’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter ended June 30, 2013 that have materially affected, or are reasonably likely to materially affect, the Bank’s internal control over financial reporting.

Assets and Liabilities Subject to Offsetting

Assets and Liabilities Subject to Offsetting [Abstract]

Assets and Liabilities Subject to Offsetting [Text Block]

Assets and Liabilities Subject to Offsetting

The Bank has derivatives and securities purchased under agreements to resell that are subject to enforceable master netting arrangements. For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting arrangement (including any cash collateral remitted to or received from the counterparty). The Bank did not have any liabilities that were eligible to offset its securities purchased under agreements to resell (i.e., securities sold under agreements to repurchase) as of June 30, 2013 or December 31, 2012.

The Bank has entered into master agreements with each of its bilateral derivative counterparties that provide for the netting of all transactions with each of these counterparties. Under its master agreements with its non-member bilateral derivative counterparties, collateral is delivered (or returned) daily when certain thresholds (ranging from $100,000 to $500,000) are met. When entering into derivative transactions with its members, the Bank requires the member to post eligible collateral in an amount equal to the sum of the net market value of the member’s derivative transactions with the Bank (if the value is positive to the Bank) plus a percentage of the notional amount of any interest rate swaps, with market values determined on at least a monthly basis. Eligible collateral for derivative transactions with members consists of collateral that is eligible to secure advances and other obligations under the member's Advances and Security Agreement with the Bank. The Bank is not required to pledge collateral to its members to secure derivative positions.

The following table presents derivative instruments and securities purchased under agreements to resell with the legal right of offset, including the related collateral received from or pledged to counterparties as of June 30, 2013 and December 31, 2012, based on the terms of the Bank's master netting arrangements (in thousands).

Recently Issued Accounting Guidance

6 Months Ended

Jun. 30, 2013

Recently Issued Accounting Guidance [Abstract]

Description of New Accounting Pronouncements Not yet Adopted [Text Block]

Recently Issued Accounting Guidance

Presentation of Comprehensive Income. On February 5, 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02"Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income"("ASU 2013-02"), which requires an entity to report, either on the face of the statement where net income is presented or in the notes, the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. The guidance in ASU 2013-02 is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2012 (January 1, 2013 for the Bank). The adoption of this guidance did not have any impact on the Bank’s results of operations or financial condition. The required disclosures are presented in Note 17.

Disclosures about Offsetting Assets and Liabilities. On December 16, 2011, the FASB issued ASU 2011-11 "Disclosures about Offsetting Assets and Liabilities," which, as clarified, requires enhanced disclosures about derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in the statement of financial position or subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset. This information is intended to enable users of an entity's financial statements to evaluate the effect or potential effect of netting arrangements on an entity's financial position, including the effect or potential effect of rights of setoff associated with these types of financial instruments.

The eligibility criteria for offsetting are different in International Financial Reporting Standards ("IFRSs") and U.S. GAAP. For example, unlike IFRSs, U.S. GAAP allows entities the option to present net in their balance sheets derivatives that are subject to a legally enforceable netting arrangement with the same party where rights of setoff are only available in the event of default or bankruptcy. The new disclosure requirements allow investors to better compare financial statements prepared in accordance with IFRSs or U.S. GAAP and improve transparency in the reporting of how entities mitigate credit risk, including disclosure of related collateral pledged or received.

The guidance is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods (January 1, 2013 for the Bank), and is to be applied retrospectively to all periods presented. The adoption of this guidance did not have any impact on the Bank’s results of operations or financial condition. The required disclosures are presented in Note 9.

Asset Classification and Charge-offs. On April 9, 2012, the Finance Agency issued Advisory Bulletin 2012-02, "Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention" ("AB 2012-02"). The guidance establishes a standard and uniform methodology for classifying assets and prescribes the timing of asset charge-offs, excluding investment securities. The guidance in AB 2012-02 is generally consistent with the Uniform Retail Credit Classification and Account Management Policy issued by the federal banking regulators in June 2000. The adoption of the accounting guidance in AB 2012-02, which is effective January 1, 2015, is not expected to have a significant impact on the Bank's results of operations or financial condition.

Joint and Several Liability Arrangements. On February 28, 2013, the FASB issued ASU 2013-04 “Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date” (“ASU 2013-04”), which provides guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of the guidance is fixed at the reporting date. ASU 2013-04 requires an entity to measure these obligations as the sum of (1) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (2) any additional amount the reporting entity expects to pay on behalf of its co-obligors. ASU 2013-04 also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The guidance in ASU 2013-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 (January 1, 2014 for the Bank) and is to be applied retrospectively to all prior periods presented. The adoption of this guidance will not have any impact on the Bank's financial condition or results of operations.

Transactions with Other FHLBanks

Occasionally, the Bank loans (or borrows) short-term federal funds to (or from) other FHLBanks. During the six months ended June 30, 2013 and 2012, interest income from loans to other FHLBanks totaled $1,507 and $744, respectively. The following table summarizes the Bank’s loans to other FHLBanks during the six months ended June 30, 2013 and 2012 (in thousands).

Derivatives and Hedging Activities

Hedging Activities. As a financial intermediary, the Bank is exposed to interest rate risk. This risk arises from a variety of financial instruments that the Bank enters into on a regular basis in the normal course of its business. The Bank enters into interest rate swap, swaption, cap and forward rate agreements (collectively, interest rate exchange agreements) to manage its exposure to changes in interest rates. The Bank may use these instruments to adjust the effective maturity, repricing frequency, or option characteristics of financial instruments to achieve risk management objectives. The Bank has not entered into any credit default swaps or foreign exchange-related derivatives, nor is it currently a party to any swaptions or forward rate agreements.

The Bank uses interest rate exchange agreements in two ways: either by designating the agreement as a fair value hedge of a specific financial instrument or firm commitment or by designating the agreement as a hedge of some defined risk in the course of its balance sheet management (referred to as an “economic hedge”). For example, the Bank uses interest rate exchange agreements in its overall interest rate risk management activities to adjust the interest rate sensitivity of consolidated obligations to approximate more closely the interest rate sensitivity of its assets (both advances and investments), and/or to adjust the interest rate sensitivity of advances or investments to approximate more closely the interest rate sensitivity of its liabilities. In addition to using interest rate exchange agreements to manage mismatches between the coupon features of its assets and liabilities, the Bank also uses interest rate exchange agreements to manage embedded options in assets and liabilities, to preserve the market value of existing assets and liabilities, to hedge the duration risk of prepayable instruments, to offset interest rate exchange agreements entered into with members (the Bank serves as an intermediary in these transactions), and to reduce funding costs.

The Bank, consistent with Finance Agency regulations, enters into interest rate exchange agreements only to reduce potential market risk exposures inherent in otherwise unhedged assets and liabilities or to act as an intermediary between its members and the Bank’s derivative counterparties. The Bank is not a derivatives dealer and it does not trade derivatives for short-term profit.

At inception, the Bank formally documents the relationships between derivatives designated as hedging instruments and their hedged items, its risk management objectives and strategies for undertaking the hedge transactions, and its method for assessing the effectiveness of the hedging relationships. This process includes linking all derivatives that are designated as fair value hedges to: (1) specific assets and liabilities on the statements of condition or (2) firm commitments. The Bank also formally assesses (both at the inception of the hedging relationship and on a monthly basis thereafter) whether the derivatives that are used in hedging transactions have been effective in offsetting changes in the fair value of hedged items and whether those derivatives may be expected to remain effective in future periods. The Bank uses regression analyses to assess the effectiveness of its hedges.

Investments — The Bank has invested in agency and non-agency MBS, all of which are classified as held-to-maturity. The interest rate and prepayment risk associated with these investment securities is managed through consolidated obligations and/or derivatives. The Bank may manage prepayment and duration risk presented by some investment securities with either callable or non-callable consolidated obligations or interest rate exchange agreements, including caps and interest rate swaps.

A substantial portion of the Bank’s held-to-maturity securities are variable-rate MBS that include caps that would limit the variable-rate coupons if short-term interest rates rise dramatically. To hedge a portion of the potential cap risk embedded in these securities, the Bank has entered into interest rate cap agreements. These derivatives are treated as economic hedges.

The Bank has also invested in agency and other highly rated debentures. Substantially all of the Bank's available-for-sale securities are fixed-rate debentures. To hedge the interest rate risk associated with these fixed-rate investment securities, the Bank entered into fixed-for-floating interest rate exchange agreements, which are designated as fair value hedges.

Advances — The Bank issues both fixed-rate and variable-rate advances. When appropriate, the Bank uses interest rate exchange agreements to adjust the interest rate sensitivity of its fixed-rate advances to approximate more closely the interest rate sensitivity of its liabilities. With issuances of putable advances, the Bank purchases from the member a put option that enables the Bank to terminate a fixed-rate advance on specified future dates. This embedded option is clearly and closely related to the host advance contract. The Bank typically hedges a putable advance by entering into a cancelable interest rate exchange agreement where the Bank pays a fixed coupon and receives a variable coupon, and sells an option to cancel the swap to the swap counterparty. This type of hedge is treated as a fair value hedge. The swap counterparty can cancel the interest rate exchange agreement on the call date and the Bank can cancel the putable advance and offer, subject to certain conditions, replacement funding at prevailing market rates.

A small portion of the Bank’s variable-rate advances are subject to interest rate caps that would limit the variable-rate coupons if short-term interest rates rise above a predetermined level. To hedge the cap risk embedded in these advances, the Bank generally enters into interest rate cap agreements. This type of hedge is treated as a fair value hedge.

The Bank may hedge a firm commitment for a forward-starting advance through the use of an interest rate swap. In this case, the swap will function as the hedging instrument for both the firm commitment and the subsequent advance. The carrying value of the firm commitment will be included in the basis of the advance at the time the commitment is terminated and the advance is issued. The basis adjustment will then be amortized into interest income over the life of the advance.

The Bank enters into optional advance commitments with its members. In an optional advance commitment, the Bank sells an option to the member that provides the member with the right to enter into an advance at a specified fixed rate and term on a specified future date, provided the member has satisfied all of the customary requirements for such advance. Optional advance commitments involving Community Investment Program (“CIP”) and Economic Development Program (“EDP”) advances with a commitment period of three months or less are currently provided at no cost to members. The Bank may hedge an optional advance commitment through the use of an interest rate swaption. In this case, the swaption will function as the hedging instrument for both the commitment and, if the option is exercised by the member, the subsequent advance. These swaptions are treated as economic hedges.

Consolidated Obligations— While consolidated obligations are the joint and several obligations of the FHLBanks, each FHLBank is the primary obligor for the consolidated obligations it has issued or assumed from another FHLBank. The Bank generally enters into derivative contracts to hedge the interest rate risk associated with its specific debt issuances.

To manage the interest rate risk of certain of its consolidated obligations, the Bank will match the cash outflow on a consolidated obligation with the cash inflow of an interest rate exchange agreement. With issuances of fixed-rate consolidated obligation bonds, the Bank typically enters into a matching interest rate exchange agreement in which the counterparty pays fixed cash flows to the Bank that are designed to mirror in timing and amount the cash outflows the Bank pays on the consolidated obligation. In this transaction, the Bank pays a variable cash flow that closely matches the interest payments it receives on short-term or variable-rate assets, typically one-month or three-month LIBOR. These transactions are treated as fair value hedges. On occasion, the Bank may enter into fixed-for-floating interest rate exchange agreements to hedge the interest rate risk associated with certain of its consolidated obligation discount notes. The derivatives associated with the Bank’s discount note hedging are treated as economic hedges. The Bank may also use interest rate exchange agreements to convert variable-rate consolidated obligation bonds from one index rate (e.g., the daily effective federal funds rate) to another index rate (e.g., one-month or three-month LIBOR); these transactions are treated as economic hedges.

The Bank has not issued consolidated obligations denominated in currencies other than U.S. dollars.

Balance Sheet Management — From time to time, the Bank may enter into interest rate basis swaps to reduce its exposure to changing spreads between one-month and three-month LIBOR. In addition, to reduce its exposure to reset risk, the Bank may occasionally enter into forward rate agreements. These derivatives are treated as economic hedges.

Intermediation — The Bank offers interest rate swaps, caps and floors to its members to assist them in meeting their hedging needs. In these transactions, the Bank acts as an intermediary for its members by entering into an interest rate exchange agreement with a member and then entering into an offsetting interest rate exchange agreement with one of the Bank’s approved derivative counterparties. All interest rate exchange agreements related to the Bank’s intermediary activities with its members are accounted for as economic hedges.

Accounting for Derivatives and Hedging Activities. The Bank accounts for derivatives and hedging activities in accordance with the guidance in Topic 815 of the FASB’s Accounting Standards Codification (“ASC”) entitled “Derivatives and Hedging” (“ASC 815”). All derivatives are recognized on the statements of condition at their fair values, including accrued interest receivable and payable. For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting arrangement (including any cash collateral remitted to or received from the counterparty).

Changes in the fair value of a derivative that is effective as — and that is designated and qualifies as — a fair value hedge, along with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk (including changes that reflect gains or losses on firm commitments), are recorded in current period earnings. Any hedge ineffectiveness (which represents the amount by which the change in the fair value of the derivative differs from the change in the fair value of the hedged item attributable to the hedged risk) is recorded in other income (loss) as “net gains (losses) on derivatives and hedging activities.” Net interest income/expense associated with derivatives that qualify for fair value hedge accounting under ASC 815 is recorded as a component of net interest income. An economic hedge is defined as a derivative hedging specific or non-specific assets or liabilities that does not qualify or was not designated for hedge accounting under ASC 815, but is an acceptable hedging strategy under the Bank’s Risk Management Policy. These hedging strategies also comply with Finance Agency regulatory requirements prohibiting speculative derivative transactions. An economic hedge by definition introduces the potential for earnings variability as changes in the fair value of a derivative designated as an economic hedge are recorded in current period earnings with no offsetting fair value adjustment to an asset or liability. Both the net interest income/expense and the fair value adjustments associated with derivatives in economic hedging relationships are recorded in other income (loss) as “net gains (losses) on derivatives and hedging activities.” Cash flows associated with derivatives are reported as cash flows from operating activities in the statements of cash flows, unless the derivatives contain an other-than-insignificant financing element, in which case the cash flows are reported as cash flows from financing activities.

If hedging relationships meet certain criteria specified in ASC 815, they are eligible for hedge accounting and the offsetting changes in fair value of the hedged items may be recorded in earnings. The application of hedge accounting generally requires the Bank to evaluate the effectiveness of the hedging relationships on an ongoing basis and to calculate the changes in fair value of the derivatives and related hedged items independently. This is commonly known as the “long-haul” method of hedge accounting. Transactions that meet more stringent criteria qualify for the “shortcut” method of hedge accounting in which an assumption can be made that the change in fair value of a hedged item exactly offsets the change in value of the related derivative. The Bank considers hedges of committed advances to be eligible for the shortcut method of accounting as long as the settlement of the committed advance occurs within the shortest period possible for that type of instrument based on market settlement conventions, the fair value of the swap is zero at the inception of the hedging relationship, and the transaction meets all of the other criteria for shortcut accounting specified in ASC 815. The Bank has defined the market settlement convention to be five business days or less for advances. The Bank records the changes in fair value of the derivative and the hedged item beginning on the trade date.

The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is “embedded” and the financial instrument that embodies the embedded derivative instrument is not remeasured at fair value with changes in fair value reported in earnings as they occur. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as either (1) a hedging instrument in a fair value hedge or (2) a stand-alone derivative instrument pursuant to an economic hedge. However, if the entire contract were to be measured at fair value, with changes in fair value reported in current earnings, or if the Bank could not reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract would be carried on the statement of condition at fair value and no portion of the contract would be separately accounted for as a derivative.

The Bank discontinues hedge accounting prospectively when: (1) management determines that the derivative is no longer effective in offsetting changes in the fair value of a hedged item; (2) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (3) a hedged firm commitment no longer meets the definition of a firm commitment; or (4) management determines that designating the derivative as a hedging instrument in accordance with ASC 815 is no longer appropriate.

When fair value hedge accounting for a specific derivative is discontinued due to the Bank’s determination that such derivative no longer qualifies for hedge accounting treatment, the Bank will continue to carry the derivative on the statement of condition at its fair value, cease to adjust the hedged asset or liability for changes in fair value, and amortize the cumulative basis adjustment on the formerly hedged item into earnings over its remaining term using the level-yield method. In all cases in which hedge accounting is discontinued and the derivative remains outstanding, the Bank will carry the derivative at its fair value on the statement of condition, recognizing changes in the fair value of the derivative in current period earnings.

When hedge accounting is discontinued because the hedged item no longer meets the definition of a firm commitment, the Bank continues to carry the derivative on the statement of condition at its fair value, removing from the statement of condition any asset or liability that was recorded to recognize the firm commitment and recording it as a gain or loss in current period earnings.

⁽¹⁾  Reported as net gains (losses) on derivatives and hedging activities in the statements of income.

⁽²⁾  The net interest income (expense) associated with derivatives in ASC 815 fair value hedging relationships is reported in the statements of income in the interest income/expense line item for the indicated hedged item.

Credit Risk Related to Derivatives. The Bank is subject to credit risk due to the risk of nonperformance by counterparties to its derivative agreements. The Bank manages derivative counterparty credit risk through the use of master netting agreements or other collateral exchange arrangements, credit analysis, and adherence to the requirements set forth in the Bank’s Risk Management Policy and Finance Agency regulations. The Bank has transacted substantially all of its interest rate exchange agreements bilaterally with large financial institutions under master netting agreements. Some of these institutions (or their affiliates) buy, sell, and distribute consolidated obligations.

The notional amount of interest rate exchange agreements does not reflect the Bank’s credit risk exposure, which is much less than the notional amount. The Bank's net credit risk exposure is based on the current estimated cost, on a present value basis, of replacing at current market rates all interest rate exchange agreements with individual counterparties, if those counterparties were to default, after taking into account the value of any cash and/or securities collateral held or remitted by the Bank. For counterparties with which the Bank is in a net gain position, the Bank has credit exposure when the collateral it is holding (if any) has a value less than the amount of the gain. For counterparties with which the Bank is in a net loss position, the Bank has credit exposure when it has delivered collateral with a value greater than the amount of the loss position. The net exposure on bilateral derivative agreements is presented in Note 9. Based on the netting provisions and collateral requirements of its master agreements and the creditworthiness of its derivative counterparties, Bank management does not currently anticipate any credit losses on its derivative agreements.

Basis of Presentation [Abstract]

Loans and Leases Receivable, Nonaccrual Loan and Lease Status, Policy [Policy Text Block]

The Bank places a conventional mortgage loan on non-accrual status when the collection of the contractual principal or interest is 90 days or more past due. When a mortgage loan is placed on non-accrual status, accrued but uncollected interest is reversed against interest income. The Bank records cash payments received on non-accrual loans first as interest income until it recovers all interest, and then as a reduction of principal. A loan on non-accrual status may be restored to accrual status when (1) none of its contractual principal and interest is due and unpaid, and the Bank expects repayment of the remaining contractual interest and principal, or (2) the loan otherwise becomes well secured and in the process of collection.

A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement. Collateral-dependent loans that are on non-accrual status are measured for impairment based on the fair value of the underlying property less estimated selling costs. Loans are considered collateral-dependent if repayment is expected to be provided solely by the sale of the underlying property; that is, there is no other available and reliable source of repayment. A collateral-dependent loan is impaired if the fair value of the underlying collateral is insufficient to recover the unpaid principal and interest on the loan. Interest income on impaired loans is recognized in the same manner as it is for non-accrual loans noted above.

The Bank evaluates whether to record a charge-off on a conventional mortgage loan upon the occurrence of a confirming event. Confirming events include, but are not limited to, the occurrence of foreclosure or notification of a claim against any of the credit enhancements. A charge-off is recorded if the recorded investment in the loan will not be recovered.

Derivatives, Offsetting Fair Value Amounts, Policy [Policy Text Block]

For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting arrangement (including any cash collateral remitted to or received from the counterparty).

Derivatives, Policy [Policy Text Block]

Accounting for Derivatives and Hedging Activities. The Bank accounts for derivatives and hedging activities in accordance with the guidance in Topic 815 of the FASB’s Accounting Standards Codification (“ASC”) entitled “Derivatives and Hedging” (“ASC 815”). All derivatives are recognized on the statements of condition at their fair values, including accrued interest receivable and payable. For purposes of reporting derivative assets and derivative liabilities, the Bank offsets the fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting arrangement (including any cash collateral remitted to or received from the counterparty).

Changes in the fair value of a derivative that is effective as — and that is designated and qualifies as — a fair value hedge, along with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk (including changes that reflect gains or losses on firm commitments), are recorded in current period earnings. Any hedge ineffectiveness (which represents the amount by which the change in the fair value of the derivative differs from the change in the fair value of the hedged item attributable to the hedged risk) is recorded in other income (loss) as “net gains (losses) on derivatives and hedging activities.” Net interest income/expense associated with derivatives that qualify for fair value hedge accounting under ASC 815 is recorded as a component of net interest income. An economic hedge is defined as a derivative hedging specific or non-specific assets or liabilities that does not qualify or was not designated for hedge accounting under ASC 815, but is an acceptable hedging strategy under the Bank’s Risk Management Policy. These hedging strategies also comply with Finance Agency regulatory requirements prohibiting speculative derivative transactions. An economic hedge by definition introduces the potential for earnings variability as changes in the fair value of a derivative designated as an economic hedge are recorded in current period earnings with no offsetting fair value adjustment to an asset or liability. Both the net interest income/expense and the fair value adjustments associated with derivatives in economic hedging relationships are recorded in other income (loss) as “net gains (losses) on derivatives and hedging activities.” Cash flows associated with derivatives are reported as cash flows from operating activities in the statements of cash flows, unless the derivatives contain an other-than-insignificant financing element, in which case the cash flows are reported as cash flows from financing activities.

If hedging relationships meet certain criteria specified in ASC 815, they are eligible for hedge accounting and the offsetting changes in fair value of the hedged items may be recorded in earnings. The application of hedge accounting generally requires the Bank to evaluate the effectiveness of the hedging relationships on an ongoing basis and to calculate the changes in fair value of the derivatives and related hedged items independently. This is commonly known as the “long-haul” method of hedge accounting. Transactions that meet more stringent criteria qualify for the “shortcut” method of hedge accounting in which an assumption can be made that the change in fair value of a hedged item exactly offsets the change in value of the related derivative. The Bank considers hedges of committed advances to be eligible for the shortcut method of accounting as long as the settlement of the committed advance occurs within the shortest period possible for that type of instrument based on market settlement conventions, the fair value of the swap is zero at the inception of the hedging relationship, and the transaction meets all of the other criteria for shortcut accounting specified in ASC 815. The Bank has defined the market settlement convention to be five business days or less for advances. The Bank records the changes in fair value of the derivative and the hedged item beginning on the trade date.

The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is “embedded” and the financial instrument that embodies the embedded derivative instrument is not remeasured at fair value with changes in fair value reported in earnings as they occur. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as either (1) a hedging instrument in a fair value hedge or (2) a stand-alone derivative instrument pursuant to an economic hedge. However, if the entire contract were to be measured at fair value, with changes in fair value reported in current earnings, or if the Bank could not reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract would be carried on the statement of condition at fair value and no portion of the contract would be separately accounted for as a derivative.

The Bank discontinues hedge accounting prospectively when: (1) management determines that the derivative is no longer effective in offsetting changes in the fair value of a hedged item; (2) the derivative and/or the hedged item expires or is sold, terminated, or exercised; (3) a hedged firm commitment no longer meets the definition of a firm commitment; or (4) management determines that designating the derivative as a hedging instrument in accordance with ASC 815 is no longer appropriate.

When fair value hedge accounting for a specific derivative is discontinued due to the Bank’s determination that such derivative no longer qualifies for hedge accounting treatment, the Bank will continue to carry the derivative on the statement of condition at its fair value, cease to adjust the hedged asset or liability for changes in fair value, and amortize the cumulative basis adjustment on the formerly hedged item into earnings over its remaining term using the level-yield method. In all cases in which hedge accounting is discontinued and the derivative remains outstanding, the Bank will carry the derivative at its fair value on the statement of condition, recognizing changes in the fair value of the derivative in current period earnings.

When hedge accounting is discontinued because the hedged item no longer meets the definition of a firm commitment, the Bank continues to carry the derivative on the statement of condition at its fair value, removing from the statement of condition any asset or liability that was recorded to recognize the firm commitment and recording it as a gain or loss in current period earnings.

Derivatives, Embedded Derivatives [Policy Text Block]

The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is “embedded” and the financial instrument that embodies the embedded derivative instrument is not remeasured at fair value with changes in fair value reported in earnings as they occur. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as either (1) a hedging instrument in a fair value hedge or (2) a stand-alone derivative instrument pursuant to an economic hedge. However, if the entire contract were to be measured at fair value, with changes in fair value reported in current earnings, or if the Bank could not reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract would be carried on the statement of condition at fair value and no portion of the contract would be separately accounted for as a derivative.

At June 30, 2013, the gross unrealized losses on the Bank’s available-for-sale securities were $5,571,000. All of the Bank's available-for-sale securities are either guaranteed by the U.S. government, issued by government-sponsored enterprises (“GSEs”), or fully secured by collateral that is guaranteed by the U.S government. As of June 30, 2013, the U.S. government and the issuers of the Bank’s holdings of GSE debentures were rated triple-A by Moody’s Investors Service (“Moody’s”) and Fitch Ratings, Ltd. (“Fitch”) and AA+ by Standard and Poor’s (“S&P”). The Bank's holdings of other debentures were rated Aaa by Moody's and AA+ by S&P at that date; the other debentures are not rated by Fitch. Based upon the Bank's assessment of the strength of the government guaranty, the Bank expects that the U.S. government-guaranteed debenture that was in an unrealized loss position at June 30, 2013 would not be settled at an amount less than the Bank's amortized cost basis in the investment. In addition, based upon the Bank’s assessment of the creditworthiness of the issuers of the GSE debentures and the credit ratings assigned by each of the nationally recognized statistical rating organizations (“NRSROs”), the Bank expects that its holdings of GSE debentures that were in an unrealized loss position at June 30, 2013 would not be settled at an amount less than the Bank’s amortized cost bases in these investments. Further, based on the creditworthiness of the issuer of the Bank's holdings of other debentures, the U.S. government's guaranty of the payment of principal and interest on the collateral securing those debentures, and the guaranty of the payment of interest on the debentures by an agency of the U.S. government, the Bank expects that its holdings of other debentures that were in an unrealized loss position at June 30, 2013 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, 2013.

Redemption Terms. The amortized cost and estimated fair value of available-for-sale securities by contractual maturity at June 30, 2013 and December 31, 2012 are presented below (in thousands).

	June 30, 2013				December 31, 2012

Basis of Accounting [Text Block]

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, 2012. 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, 2012 filed with the SEC on March 25, 2013 (the “2012 10-K”). The notes to the interim financial statements update and/or highlight significant changes to the notes included in the 2012 10-K.

The Bank is one of 12 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 FHLBanks and the Office of Finance.

Use of Estimates. 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 assumptions include those that are used by the Bank in its periodic evaluation of its holdings of non-agency residential mortgage-backed securities for other-than-temporary impairment (“OTTI”). 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.

Allowance for Credit Losses

Allowance for Credit Losses [Abstract]

Allowance for Credit Losses [Text Block]

Allowance for Credit Losses

An allowance for credit losses is separately established for each of the Bank’s identified portfolio segments, if necessary, to provide for probable losses inherent in its financing receivables portfolio and other off-balance sheet credit exposures as of the balance sheet date. To the extent necessary, an allowance for credit losses for off-balance sheet credit exposures is recorded as a liability.

A portfolio segment is defined as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses. The Bank has developed and documented a systematic methodology for determining an allowance for credit losses for the following portfolio segments: (1) advances and other extensions of credit to members, collectively referred to as “extensions of credit to members;” (2) government-guaranteed/insured mortgage loans held for portfolio; and (3) conventional mortgage loans held for portfolio.

Classes of financing receivables are generally a disaggregation of a portfolio segment and are determined on the basis of their initial measurement attribute, the risk characteristics of the financing receivable and an entity’s method for monitoring and assessing credit risk. Because the credit risk arising from the Bank’s financing receivables is assessed and measured at the portfolio segment level, the Bank does not have separate classes of financing receivables within each of its portfolio segments.

During the six months ended June 30, 2013 and 2012, there were no purchases or sales of financing receivables, nor were any financing receivables reclassified to held for sale.

Advances and Other Extensions of Credit to Members. In accordance with federal statutes, including the Federal Home Loan Bank Act of 1932, as amended (the “FHLB Act”), the Bank lends to financial institutions within its five-state district that are involved in housing finance. The FHLB Act requires the Bank to obtain and maintain sufficient collateral for advances and other extensions of credit to protect against losses. The Bank makes advances and otherwise extends credit only against eligible collateral, as defined by regulation. To ensure the value of collateral pledged to the Bank is sufficient to secure its advances and other extensions of credit, the Bank applies various haircuts, or discounts, to the collateral to determine the value against which borrowers may borrow. As additional security, the Bank has a statutory lien on each borrower’s capital stock in the Bank.

On at least a quarterly basis, the Bank evaluates all outstanding extensions of credit to members/borrowers for potential credit losses. These evaluations include a review of: (1) the amount, type and performance of collateral available to secure the outstanding obligations; (2) metrics that may be indicative of changes in the financial condition and general creditworthiness of the member/borrower; and (3) the payment status of the obligations. Any outstanding extensions of credit that exhibit a potential credit weakness that could jeopardize the full collection of the outstanding obligations would be classified as substandard, doubtful or loss. The Bank did not have any advances or other extensions of credit to members/borrowers that were classified as substandard, doubtful or loss at June 30, 2013 or December 31, 2012.

The Bank considers the amount, type and performance of collateral to be the primary indicator of credit quality with respect to its extensions of credit to members/borrowers. At June 30, 2013 and December 31, 2012, the Bank had rights to collateral on a borrower-by-borrower basis with an estimated value in excess of each borrower’s outstanding extensions of credit.

The Bank continues to evaluate and, as necessary, modify its credit extension and collateral policies based on market conditions. At June 30, 2013 and December 31, 2012, the Bank did not have any advances that were past due, on non-accrual status, or considered impaired. There have been no troubled debt restructurings related to advances.

The Bank has never experienced a credit loss on an advance or any other extension of credit to a member/borrower and, based on its credit extension and collateral policies, management currently does not anticipate any credit losses on its extensions of credit to members/borrowers. Accordingly, the Bank has not provided any allowance for credit losses on advances, nor has it recorded any liabilities to reflect an allowance for credit losses related to its off-balance sheet credit exposures.

Mortgage Loans — Government-guaranteed/Insured. The Bank’s government-guaranteed/insured fixed-rate mortgage loans are insured or guaranteed by the Federal Housing Administration or the Department of Veterans Affairs. Any losses from these loans are expected to be recovered from those entities. Any losses from these loans that are not recovered from those entities are absorbed by the servicers. Therefore, the Bank has not established an allowance for credit losses on government-guaranteed/insured mortgage loans. Government-guaranteed/insured loans are not placed on non-accrual status.

Mortgage Loans — Conventional Mortgage Loans. The Bank’s conventional mortgage loans were acquired through the Mortgage Partnership Finance^® (“MPF”^®) program, as more fully described in the Bank’s 2012 10-K. The allowance for losses on conventional mortgage loans is determined by an analysis that includes consideration of various data such as past performance, current performance, loan portfolio characteristics, collateral-related characteristics, industry data, and prevailing economic conditions. The allowance for losses on conventional mortgage loans also factors in the credit enhancement under the MPF program. Any incurred losses that are expected to be recovered from the credit enhancements are not reserved as part of the Bank’s allowance for loan losses.

The Bank places a conventional mortgage loan on non-accrual status when the collection of the contractual principal or interest is 90 days or more past due. When a mortgage loan is placed on non-accrual status, accrued but uncollected interest is reversed against interest income. The Bank records cash payments received on non-accrual loans first as interest income until it recovers all interest, and then as a reduction of principal. A loan on non-accrual status may be restored to accrual status when (1) none of its contractual principal and interest is due and unpaid, and the Bank expects repayment of the remaining contractual interest and principal, or (2) the loan otherwise becomes well secured and in the process of collection.

A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement. Collateral-dependent loans that are on non-accrual status are measured for impairment based on the fair value of the underlying property less estimated selling costs. Loans are considered collateral-dependent if repayment is expected to be provided solely by the sale of the underlying property; that is, there is no other available and reliable source of repayment. A collateral-dependent loan is impaired if the fair value of the underlying collateral is insufficient to recover the unpaid principal and interest on the loan. Interest income on impaired loans is recognized in the same manner as it is for non-accrual loans noted above.

The Bank evaluates whether to record a charge-off on a conventional mortgage loan upon the occurrence of a confirming event. Confirming events include, but are not limited to, the occurrence of foreclosure or notification of a claim against any of the credit enhancements. A charge-off is recorded if the recorded investment in the loan will not be recovered.

The Bank considers the key credit quality indicator for conventional mortgage loans to be the payment status of each loan. The table below summarizes the unpaid principal balance by payment status for mortgage loans at June 30, 2013 and December 31, 2012 (dollars in thousands). The unpaid principal balance approximates the recorded investment in the loans.

At June 30, 2013 and December 31, 2012, the Bank’s other assets included $204,000 and $25,000, respectively, of real estate owned.

Mortgage loans are considered impaired when, based upon current information and events, it is probable that the Bank will be unable to collect all principal and interest amounts due according to the contractual terms of the mortgage loan agreement. Each non-accrual mortgage loan and each troubled debt restructuring is specifically reviewed for impairment. At June 30, 2013 and December 31, 2012, the estimated value of the collateral securing each of these loans was in excess of the outstanding loan amount. Therefore, no specific reserve was established for any of these mortgage loans. The remaining conventional mortgage loans were evaluated for impairment on a pool basis. Based upon the current and past performance of these loans, the underwriting standards in place at the time the loans were acquired, and current economic conditions, the Bank determined that an allowance for loan losses of $175,000 was adequate to reserve for credit losses in its conventional mortgage loan portfolio at June 30, 2013. The following table presents the activity in the allowance for credit losses on conventional mortgage loans held for portfolio during the three and six months ended June 30, 2013 and 2012 (in thousands):

Transactions with Shareholders

Affiliates of two of the Bank’s derivative counterparties (Citigroup and Wells Fargo) acquired member institutions on March 31, 2005 and October 1, 2006, respectively. Since the acquisitions were completed, the Bank has continued to enter into interest rate exchange agreements with Citigroup and Wells Fargo in the normal course of business and under the same terms and conditions as before. Effective October 1, 2006, Citigroup terminated the Ninth District charter of the affiliate that acquired the member institution and, as a result, an affiliate of Citigroup became a non-member shareholder of the Bank.

The balance of overdrawn demand deposit accounts was fully collateralized at December 31, 2012 and was repaid in early January 2013. Amortizing advances require repayment according to predetermined amortization schedules.

The Bank offers advances to members that may be prepaid on specified dates without the member incurring prepayment or termination fees (prepayable and callable advances). The prepayment of other advances requires the payment of a fee to the Bank (prepayment fee) if necessary to make the Bank financially indifferent to the prepayment of the advance. At June 30, 2013 and December 31, 2012, the Bank had aggregate prepayable and callable advances totaling $114,253,000 and $121,123,000, respectively.

The following table summarizes advances outstanding at June 30, 2013 and December 31, 2012, by the earliest of contractual maturity, next call date, or the first date on which prepayable advances can be repaid without a prepayment fee (in thousands):

Contractual Maturity or Next Call Date	June 30, 2013		December 31, 2012
Overdrawn demand deposit accounts	$	—	$	7,682
Due in one year or less	9,929,175		8,955,062
Due after one year through two years	1,089,780		1,881,603
Due after two years through three years	930,033		942,691
Due after three years through four years	881,797		434,521
Due after four years through five years	1,780,335		1,865,480

Amortizing advances	2,130,083		2,319,538
Total par value	$	18,056,016	$	17,928,256

The Bank also offers putable advances. With a putable advance, the Bank purchases a put option from the member that allows the Bank to terminate the fixed-rate advance on specified dates and offer, subject to certain conditions, replacement funding at prevailing market rates. At June 30, 2013 and December 31, 2012, the Bank had putable advances outstanding totaling $2,305,471,000 and $2,572,471,000, respectively.

The following table summarizes advances outstanding at June 30, 2013 and December 31, 2012, by the earlier of contractual maturity or next possible put date (in thousands):

Contractual Maturity or Next Put Date	June 30, 2013		December 31, 2012
Overdrawn demand deposit accounts	$	—	$	7,682
Due in one year or less	12,147,646		11,193,533

Due after two years through three years	813,533		786,691
Due after three years through four years	631,797		392,021
Due after four years through five years	481,264		601,359

Total par value	$	18,056,016	$	17,928,256

Interest Rate Payment Terms. The following table provides interest rate payment terms for advances outstanding at June 30, 2013 and December 31, 2012 (in thousands):

	June 30, 2013		December 31, 2012
Fixed-rate
Due in one year or less	$	8,942,965	$	7,979,254
Due after one year	8,058,051		7,883,320
Total fixed-rate	17,001,016		15,862,574
Variable-rate
Due in one year or less	1,011,000		1,016,682
Due after one year	44,000		1,049,000
Total variable-rate	1,055,000		2,065,682
Total par value	$	18,056,016	$	17,928,256

At June 30, 2013 and December 31, 2012, 35 percent and 42 percent, respectively, of the Bank’s fixed-rate advances were swapped to a variable rate.

Prepayment Fees. When a member/borrower prepays an advance, the Bank could suffer lower future income if the principal portion of the prepaid advance is reinvested in lower-yielding assets. To protect against this risk, the Bank generally charges a prepayment fee that makes it financially indifferent to a borrower’s decision to prepay an advance. The Bank records prepayment fees received from members/borrowers on prepaid advances net of any associated hedging adjustments on those advances. These fees are reflected as interest income in the statements of income either immediately (as prepayment fees on advances) or over time (as interest income on advances) as further described below. In cases in which the Bank funds a new advance concurrent with or within a short period of time before or after the prepayment of an existing advance and the advance meets the accounting criteria to qualify as a modification of the prepaid advance, the net prepayment fee on the prepaid advance is deferred, recorded in the basis of the modified advance, and amortized into interest income over the life of the modified advance using the level-yield method. During the three months ended June 30, 2013 and 2012, gross advance prepayment fees received from members/borrowers were $9,396,000 and $2,145,000, respectively, of which $95,000 and $128,000, respectively, were deferred. During the six months ended June 30, 2013 and 2012, gross advance prepayment fees received from members/borrowers were $10,004,000 and $5,783,000, respectively, of which $246,000 and $432,000, respectively, were deferred.

At June 30, 2013, the gross unrealized losses on the Bank’s held-to-maturity securities were $24,330,000, of which $23,116,000 was attributable to its holdings of non-agency (i.e., private-label) residential mortgage-backed securities and $1,214,000 was attributable to securities that are either guaranteed by the U.S. government or issued and guaranteed by GSEs. As of June 30, 2013, the U.S. government and the issuers of the Bank’s holdings of GSE mortgage-backed securities ("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 guarantees of the debentures held by the Bank, the credit ratings assigned by the NRSROs and the strength of the GSEs’ guarantees of the Bank’s holdings of agency MBS, the Bank expects that its holdings of U.S. government-guaranteed debentures and GSE MBS that were in an unrealized loss position at June 30, 2013 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 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, 2013.

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. Based on its analysis of the securities in this portfolio, however, the Bank believes that the unrealized losses as of June 30, 2013 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 30 non-agency RMBS holdings are likely to be recovered, the Bank performed a cash flow analysis for each security as of June 30, 2013 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, 2013 assumed changes in home prices ranging from declines of 5 percent to increases of 7 percent over the 12-month period beginning April 1, 2013. For the vast majority of markets, the changes were projected to range from declines of 3 percent to increases of 5 percent. Thereafter, home prices were projected to recover using one of five different recovery paths that vary by housing market. Under those recovery paths, home prices were projected to increase as set forth in the table below.

Months	Range of Annualized Rates
1 - 6	0.0	%	-	3.0%
7 - 12	1.0	%	-	4.0%
13 - 18	2.0	%	-	4.0%
19 - 30	2.0	%	-	5.0%
31 - 54	2.0	%	-	6.0%
Thereafter	2.3	%	-	5.6%

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 these securities were deemed to be other-than-temporarily impaired as of June 30, 2013.

Prior to July 1, 2012, 14 of the Bank's holdings of non-agency RMBS were determined to be other-than-temporarily impaired. The following table sets forth additional information for each of the securities that was deemed to be other-than-temporarily impaired in a prior period (in thousands). All of the Bank’s non-agency RMBS are rated by Moody’s, S&P and/or Fitch. The credit ratings presented in the table represent the lowest rating assigned to the security by any of these NRSROs as of June 30, 2013.

Shareholders are required to maintain an investment in Class B stock equal to the sum of a membership investment requirement and an activity-based investment requirement. The membership investment requirement is currently 0.04 percent of each member's total assets as of December 31, 2012, subject to a minimum of $1,000 and a maximum of $7,000,000. The activity-based investment requirement is currently 4.10 percent of outstanding advances.

The Bank generally repurchases surplus stock on the last business day of the month following the end of each calendar quarter. For the repurchases that occurred on January 31, 2013, April 30, 2013 and July 31, 2013, surplus stock was defined as the amount of stock held by a member in excess of 102.5 percent of the member’s minimum investment requirement. For the repurchases that occurred on January 31, 2013, April 30, 2013 and July 31, 2013, a member's surplus stock was not repurchased if the amount of that member's surplus stock was $100,000 or less or if, subject to certain exceptions, the member was on restricted collateral status. On January 31, 2013, April 30, 2013 and July 31, 2013, the Bank repurchased surplus stock totaling $198,427,400, $168,555,900 and $182,879,400, respectively, none of which was classified as mandatorily redeemable capital stock at those dates.

Debt Disclosure [Abstract]

Debt and Capital Leases Disclosures [Text Block]

Consolidated Obligations

Consolidated obligations are the joint and several obligations of the FHLBanks and consist of consolidated obligation bonds and discount notes. Consolidated obligations are backed only by the financial resources of the 12 FHLBanks. Consolidated obligations are not obligations of, nor are they guaranteed by, the U.S. government. The FHLBanks issue consolidated obligations through the Office of Finance as their agent. In connection with each debt issuance, one or more of the FHLBanks specifies the amount of debt it wants issued on its behalf; the Bank receives the proceeds only of the debt issued on its behalf and is the primary obligor only for the portion of bonds and discount notes for which it has received the proceeds. The Bank records on its statements of condition only that portion of the consolidated obligations for which it is the primary obligor. Consolidated obligation bonds are issued primarily to raise intermediate- and long-term funds for the FHLBanks and are not subject to any statutory or regulatory limits on maturity. Consolidated obligation discount notes are issued to raise short-term funds and have maturities of one year or less. These notes are issued at a price that is less than their face amount and are redeemed at par value when they mature. For additional information regarding the FHLBanks’ joint and several liability on consolidated obligations, see Note 14.

The par amounts of the 12 FHLBanks’ outstanding consolidated obligations, including consolidated obligations held as investments by other FHLBanks, were approximately $705 billion and $688 billion at June 30, 2013 and December 31, 2012, respectively. The Bank was the primary obligor on $29.8 billion and $32.6 billion (at par value), respectively, of these consolidated obligations.

Interest Rate Payment Terms. The following table summarizes the Bank’s consolidated obligation bonds outstanding by interest rate payment terms at June 30, 2013 and December 31, 2012 (in thousands, at par value).

Commitments and Contingencies

Joint and several liability. The Bank is jointly and severally liable with the other 11 FHLBanks for the payment of principal and interest on all of the consolidated obligations issued by the 12 FHLBanks. At June 30, 2013, the par amount of the other 11 FHLBanks’ outstanding consolidated obligations was approximately $675 billion. The Finance Agency, in its discretion, may require any FHLBank to make principal or interest payments due on any consolidated obligation, regardless of whether there has been a default by a FHLBank having primary liability. To the extent that a FHLBank makes any consolidated obligation payment on behalf of another FHLBank, the paying FHLBank is entitled to reimbursement from the FHLBank with primary liability. However, if the Finance Agency determines that the primary obligor is unable to satisfy its obligations, then the Finance Agency may allocate the outstanding liability among the remaining FHLBanks on a pro rata basis in proportion to each FHLBank’s participation in all consolidated obligations outstanding, or on any other basis that the Finance Agency may determine. No FHLBank has ever failed to make any payment on a consolidated obligation for which it was the primary obligor; as a result, the regulatory provisions for directing other FHLBanks to make payments on behalf of another FHLBank or allocating the liability among other FHLBanks have never been invoked. If the Bank were to determine that a loss was probable under its joint and several liability and the amount of such loss could be reasonably estimated, the Bank would charge to income the amount of the expected loss. Based upon the creditworthiness of the other FHLBanks, the Bank currently believes that the likelihood of a loss arising from its joint and several liability is remote.

Other commitments and contingencies. At June 30, 2013 and December 31, 2012, the Bank had commitments to make additional advances totaling approximately $35,663,000 and $77,212,000, respectively. In addition, outstanding standby letters of credit totaled $2,999,341,000 and $2,947,267,000 at June 30, 2013 and December 31, 2012, respectively. Based on management’s credit analyses and collateral requirements, the Bank does not deem it necessary to have any provision for credit losses on these letters of credit (see Note 6).

At June 30, 2013, the Bank had a commitment to issue a $40,000,000 consolidated obligation bond, which was hedged with an interest rate swap. The Bank did not have any commitments to issue consolidated obligations at December 31, 2012.

The Bank has executed interest rate exchange agreements with large financial institutions with which it has bilateral collateral exchange agreements. As of June 30, 2013 and December 31, 2012, the Bank had pledged cash collateral of $972,207,000 and $1,228,375,000, respectively, to those financial institutions that had credit risk exposure to the Bank related to interest rate exchange agreements. The pledged cash collateral (i.e., interest-bearing deposit asset) is netted against derivative assets and liabilities in the statements of condition.

In the ordinary course of its business, the Bank is subject to the risk that litigation may arise. Currently, the Bank is not a party to any material pending legal proceedings.

Estimated Fair Values

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

Estimated Fair Values

Fair value is defined under U.S. GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. U.S. GAAP establishes a fair value hierarchy and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. U.S. GAAP also requires an entity to disclose the level within the fair value hierarchy in which each measurement is classified. The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels:

Level 1 Inputs — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

Level 2 Inputs — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include the following: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active or in which little information is released publicly; (3) inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals and implied volatilities); and (4) inputs that are derived principally from or corroborated by observable market data (e.g., implied spreads).

Level 3 Inputs — Unobservable inputs for the asset or liability that are supported by little or no market activity. None of the Bank’s assets or liabilities that are recorded at fair value on a recurring basis were measured using significant Level 3 inputs.

The following estimated fair value amounts have been determined by the Bank using available market information and the Bank’s best judgment of appropriate valuation methods. These estimates are based on pertinent information available to the Bank as of June 30, 2013 and December 31, 2012. Although the Bank uses its best judgment in estimating the fair value of these financial instruments, there are inherent limitations in any estimation technique or valuation methodology. For example, because an active secondary market does not exist for many of the Bank’s financial instruments (e.g., advances, non-agency RMBS and mortgage loans held for portfolio), in certain cases their fair values are not subject to precise quantification or verification. Therefore, the estimated fair values presented below in the Fair Value Summary Tables may not be indicative of the amounts that would have been realized in market transactions at the reporting dates. Further, the fair values do not represent an estimate of the overall market value of the Bank as a going concern, which would take into account future business opportunities.

The valuation techniques used to measure the fair values of the Bank’s financial instruments are described below.

Cash and due from banks. The estimated fair value equals the carrying value.

Interest-bearing deposit assets. Interest-bearing deposit assets earn interest at floating market rates; therefore, the estimated fair value of the deposits approximates their carrying value.

  Securities purchased under agreements to resell and federal funds sold. All federal funds sold and securities purchased under agreements to resell represent overnight balances. The estimated fair values approximate the carrying values.

Trading securities. The Bank obtains quoted prices for identical securities.

Available-for-sale and held-to-maturity securities. To value its available-for-sale securities and its held-to-maturity MBS holdings, the Bank obtains prices from four designated third-party pricing vendors when available. The pricing vendors use various proprietary models to price these securities. The inputs to those models are derived from various sources including, but not limited to: benchmark yields, reported trades, dealer estimates, issuer spreads, benchmark securities, bids, offers and other market-related data. Because many securities do not trade on a daily basis, the pricing vendors use available information as applicable such as benchmark curves, benchmarking of like securities, sector groupings and matrix pricing to determine the prices for individual securities. Each pricing vendor has an established challenge process in place for all security valuations, which facilitates resolution of potentially erroneous prices identified by the Bank.

A "median" price is first established for each security using a formula that is based upon the number of prices received. If four prices are received, the average of the middle two prices is the median price; if three prices are received, the middle price is the median price; if two prices are received, the average of the two prices is the median price; and if one price is received, it is the median price (and also the final price) subject to some type of validation similar to the evaluation of outliers described below. All prices that are within a specified tolerance threshold of the median price are included in the “cluster” of prices that are averaged to compute a “default” price. All prices that are outside the threshold (“outliers”) are subject to further analysis (including, but not limited to, comparison to prices provided by an additional third-party valuation service, prices for similar securities, and/or non-binding dealer estimates) to determine if an outlier is a better estimate of fair value. If an outlier (or some other price identified in the analysis) is determined to be a better estimate of fair value, then the outlier (or the other price, as appropriate) is used as the final price rather than the default price. If, on the other hand, the analysis confirms that an outlier (or outliers) is (are) in fact not representative of fair value and the default price is the best estimate, then the default price is used as the final price. In all cases, the final price is used to determine the fair value of the security.

If all prices received for a security are outside the tolerance threshold level of the median price, then there is no default price, and the final price is determined by an evaluation of all outlier prices as described above.

As an additional step, the Bank reviewed the final fair value estimates of its non-agency RMBS holdings as of June 30, 2013 for reasonableness using an implied yield test. The Bank calculated an implied yield for each of its non-agency RMBS using the estimated fair value derived from the process described above and the security's projected cash flows from the Bank's OTTI process and compared those yields to the yields for comparable securities according to dealers and other third-party sources to the extent comparable market yield data was available. This analysis did not indicate that any adjustments to the final fair value estimates were necessary.

As of June 30, 2013, four vendor prices were received for substantially all of the Bank’s available-for-sale securities and held-to-maturity MBS holdings and the final prices for substantially all of those securities were computed by averaging the four prices. Based on the Bank's understanding of the pricing methods employed by the third-party pricing vendors and the relative lack of dispersion among the vendor prices (or, in those instances in which there were outliers or significant yield variances, the Bank's additional analyses), the Bank believes its final prices result in reasonable estimates of the fair values and that the fair value measurements are classified appropriately in the fair value hierarchy.

The Bank estimates the fair values of its held-to-maturity debentures using a pricing model and observable market data (i.e., the U.S. Government Agency Fair Value curve and, for debentures containing call features, swaption volatility).

Advances. The Bank determines the estimated fair values of advances by calculating the present value of expected future cash flows from the advances using the replacement advance rates for advances with similar terms and, for advances containing options, swaption volatility. This amount is then reduced for accrued interest receivable. Each FHLBank prices advances at a spread to its cost of funds. Each FHLBank's cost of funds approximates the "CO curve," which is derived by adding to the U.S. Treasury curve indicative spreads obtained from market-observable sources. The indicative spreads are generally derived from dealer pricing indications, recent trades, secondary market activity and historical pricing relationships.

Mortgage loans held for portfolio. The Bank estimates the fair values of mortgage loans held for portfolio based on observed market prices for agency MBS. Individual mortgage loans are pooled based on certain criteria such as loan type, weighted average coupon, and origination year and matched to reference securities with a similar collateral composition to derive benchmark pricing. The prices for agency MBS used as a benchmark are subject to certain market conditions including, but not limited to, the market’s expectations of future prepayments, the current and expected level of interest rates, and investor demand.

Accrued interest receivable and payable. The estimated fair value of accrued interest receivable and payable approximates the carrying value due to their short-term nature.

Derivative assets/liabilities. With the exception of its interest rate basis swaps, the fair values of the Bank’s interest rate swap and swaption agreements are estimated using a pricing model with inputs that are observable in the market (e.g., the relevant interest rate curves (that is, the relevant LIBOR swap curve and, for purposes of discounting, the overnight index swap ("OIS") curve) and, for agreements containing options, swaption volatility). Prior to December 31, 2012, the Bank used the LIBOR swap curve to discount cash flows when determining the fair values of its interest rate exchange agreements. The Bank determined that most market participants had as of December 31, 2012 begun using the OIS curve to value certain collateralized interest rate exchange agreements and, as a result, the Bank concluded that the OIS curve was a more appropriate curve to use to discount the cash flows on its interest rate exchange agreements beginning on that date.

As the provisions of the credit support annexes to the Bank’s master agreements with its derivative counterparties significantly reduce the risk from nonperformance (see Note 9), the Bank does not consider its own nonperformance risk or the nonperformance risk associated with each of its counterparties to be a significant factor in the valuation of its derivative assets and liabilities. The Bank compares the fair values obtained from its pricing model to non-binding dealer estimates and may also compare its fair values to those of similar instruments to ensure that the fair values are reasonable. For the Bank’s interest rate basis swaps, fair values are obtained from dealers (for each basis swap, one dealer estimate is received); the non-binding fair value estimates as of June 30, 2013 and December 31, 2012 were corroborated using a pricing model and observable market data (i.e., the relevant LIBOR swap curve and, for purposes of discounting, the OIS curve).

For the Bank’s interest rate caps, fair values are obtained from dealers (for each interest rate cap, one dealer estimate is received). The non-binding fair value estimates as of June 30, 2013 and December 31, 2012 were corroborated using a pricing model and observable market data (i.e., cap volatility, the relevant LIBOR swap curve and, for purposes of discounting, the OIS curve).

The fair values of the Bank’s derivative assets and liabilities include accrued interest receivable/payable and, in the case of derivatives executed under master netting arrangements, cash collateral remitted to/received from counterparties; the estimated fair values of the accrued interest receivable/payable and cash collateral approximate their carrying values due to their short-term nature. The fair values of the Bank's bilateral derivatives are netted by counterparty pursuant to the provisions of the credit support annexes to the Bank’s master agreements with its non-member bilateral derivative counterparties. If these netted amounts are positive, they are classified as an asset and, if negative, as a liability.

Deposit liabilities. The Bank determines the estimated fair values of its deposit liabilities with fixed rates and more than three months to maturity by calculating the present value of expected future cash flows from the deposits and reducing this amount for accrued interest payable. The discount rates used in these calculations are based on replacement funding rates for liabilities with similar terms. The estimated fair value approximates the carrying value for deposits with variable rates and fixed rates with three months or less to their maturity or repricing date.

Consolidated obligations. The Bank estimates the fair values of consolidated obligations by calculating the present value of expected future cash flows using discount rates that are based on replacement funding rates for liabilities with similar terms and reducing this amount for accrued interest payable. The inputs to the valuation are the CO curve and, for consolidated obligations containing options, swaption volatility.

Mandatorily redeemable capital stock. The fair value of capital stock subject to mandatory redemption is generally equal to its par value ($100 per share), as adjusted for any estimated dividend earned but unpaid at the time of reclassification from equity to liabilities. The Bank’s capital stock cannot, by statute or implementing regulation, be purchased, redeemed, repurchased or transferred at any amount other than its par value.

Commitments. The Bank determined the estimated fair values of optional commitments to fund advances by calculating the present value of expected future cash flows from the instruments using replacement advance rates for advances with similar terms and swaption volatility. The estimated fair value of the Bank’s other commitments to extend credit, including advances and letters of credit, was not material at June 30, 2013 or December 31, 2012.

The following table presents the carrying values and estimated fair values of the Bank’s financial instruments at June 30, 2013 (in thousands), as well as the level within the fair value hierarchy in which the measurements are classified. Financial assets and liabilities are classified in their entirety based on the lowest level input that is significant to the fair value estimate.

As of December 31, 2012, the Bank had entered into optional advance commitments with par values totaling $50,000,000, excluding commitments to fund CIP and EDP advances. These commitments expired during the three months ended March 31, 2013. Under each of these commitments, the Bank sold an option to a member that provided the member with the right to enter into an advance at a specified fixed rate and term on a specified future date, provided the member had satisfied all of the customary requirements for that advance. The Bank hedged these commitments through the use of interest rate swaptions, which were treated as economic hedges. The Bank irrevocably elected to carry these optional advance commitments at fair value under the fair value option in an effort to mitigate the potential income statement volatility that can arise from economic hedging relationships. Gains and losses on optional advance commitments carried at fair value under the fair value option are reported in other income (loss) in the statements of income. The optional advance commitments were reported in other liabilities in the statement of condition as of December 31, 2012. At December 31, 2012, the fair value of these optional advance commitments totaled less than $1,000. At that same date, other liabilities included items with an aggregate carrying value of $25,085,000 that were not eligible for the fair value option.
