Note 1 – Background and Basis of Presentation

The Federal Home Loan Bank of Chicago is a federally chartered corporation and one of 11 Federal Home Loan Banks (the FHLBs) that, with the Office of Finance, comprise the Federal Home Loan Bank System (the System). The FHLBs are government-sponsored enterprises (GSE) of the United States of America and were organized under the Federal Home Loan Bank Act of 1932, as amended (FHLB Act), in order to improve the availability of funds to support home ownership. We are supervised and regulated by the Federal Housing Finance Agency (FHFA), an independent federal agency in the executive branch of the United States (U.S.) government.

Each FHLB is a member-owned cooperative with members from a specifically defined geographic district. Our defined geographic district is Illinois and Wisconsin. All federally-insured depository institutions, insurance companies engaged in residential housing finance, credit unions and community development financial institutions located in our district are eligible to apply for membership with us.

Use of Estimates and Assumptions

We are required to make estimates and assumptions when preparing our financial statements in accordance with GAAP. The most significant of these estimates and assumptions applies to fair value measurements and allowance for credit losses. Our actual results may differ from the results reported in our financial statements due to such estimates and assumptions. This includes the reported amounts of assets and liabilities, the reported amounts of income and expense, and the disclosure of contingent assets and liabilities.

~~Consolidation~~Basis of ~~Variable Interest Entities~~Presentation

~~We are not~~The basis of presentation pertaining to the ~~primary beneficiary~~consolidation of any variable interest entity. Specifically, we do not have the power to direct the activities of any variable interest entity that would most significantly impact its economic performance and we do not have the obligation to absorb losses or the right to receive benefits from any variable interest entity that could potentially be significant to a variable interest entity. As a result, we do not consolidate any of our ~~investments in variable interest entities. Instead, we classify~~ variable interest entities ~~as investment securities~~has not changed since we filed our 2017 Form 10-K.

~~Gross versus Net Presentation of Financial Instruments~~

Our over-the-counter derivative transactions may be entered into through a bilateral agreement with an individual counterparty. We present these derivative transactions on a net basis in our statements of condition on the basis that our right to net amounts due to our counterparties is enforceable at law upon early termination. Derivatives are netted by contract (e.g., master netting agreement), to discharge all or a portion of the amounts that would be owed to our counterparty by applying them against the amounts that our counterparty owes to us. If these netted amounts are positive, they are classified as a derivative asset and if negative, they are classified as a derivative liability. The net exposure for these financial instruments can change on a daily basis; therefore, there may be a delay between the time this exposure change is identified and additional collateral is requested, and the time when this collateral is received or pledged. Likewise, there may be a delay for excess collateral to be returned. For derivative instruments that meet the netting requirements, any excess cash collateral received or pledged is recognized as a derivative liability or asset.

We also enter into cleared derivative transactions with clearinghouses classified as a Derivatives Clearing Organization (DCO) through a Futures Commission Merchant (FCM), a clearing member of the DCO. Prior to 2017, our accounting presented derivative assets and liabilities of our cleared derivative transactions on a net basis, inclusive of initial and variation margin, and accrued interest receivable/payable and cash collateral. Due to rule changes adopted by our DCOs that characterize the treatment of variation margin payments as settlement of a derivative’s mark-to-market exposure and not as collateral against the derivative’s mark-to-market exposure, we now account for our variation margin payments as settlements to our derivative assets and derivative liabilities. The amendments to the DCOs’ rules have no effect on how we present initial margin, which we include in the carrying amount of our derivative assets or derivative liabilities.

~~See~~ ~~Note 9 - Derivatives and Hedging Activities~~ ~~for further details.~~

~~Our policy is to report securities purchased under agreements to resell and securities sold under agreements to repurchase, if any, and securities borrowing transactions, if any, on a gross basis.~~

Note 2 – Summary of Significant Accounting Policies

Our Summary of Significant Accounting Policies through December 31, ~~2016,~~2017, can be found in Note 2 – Summary of Significant Accounting Policies to the financial statements in our ~~2016~~2017 Form 10-K. We adopted the following policies ~~year to date in 2017:~~effective January 1, 2018:

~~Accounting for Variation Margin Payments~~Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01)

~~Effective in January~~We are required to recognize the portion of ~~2017 we began accounting for variation margin payments made~~instrument-specific credit risk attributable to ~~or received by~~ the ~~DCOs through our FCMs as settlements to our cleared derivative assets and derivative liabilities. See~~ ~~Note 1 - Background and Basis for Presentation~~ ~~for further details. This~~total change in ~~accounting~~fair value of our consolidated obligations that are carried at fair value in our statements of comprehensive income. We measure such instrument-specific credit risk based on our nonperformance risk, which includes our nonperformance risk and the credit risk associated with the joint and several liability of other FHLBs. The new guidance did not have ~~any~~an effect on our financial condition, results of operations, and cash flows at the ~~accounting~~time of our existing hedge relationships. Specifically, the change in accounting would not require us to discontinue existing hedge relationships or preclude us from using the short-cut method of hedge accounting provided no additional changes are made by the DCOs that would preclude the use of the short-cut method of hedge accounting. The International Swaps and Derivatives Association (ISDA) issued a confirmation letter confirming the SEC staff’s non-objection to the conclusions reached by ISDA related to the accounting implications of the DCO rule changes regarding the characterization of the variation margin payments as daily settlements and the continued application of existing hedge accounting relationships, including the use of the short-cut method of hedge accounting.

~~Contingent Put and Call Options in Debt Instruments~~adoption.

In March of 2016, the FASB issued new guidance clarifying the requirements for assessing whether a contingent call (put) option embedded in a debt instrument is clearly and closely related to that debt instrument, which is referred to the "host contract" for purposes of this assessment. Specifically, we are no longer required to consider the event triggering the acceleration of an embedded contingent call (put) option when assessing whether it is clearly and closely related to the debt instrument or host contract. We adopted the new guidance effective January 1, 2017. Revenue from Contracts with Customers (ASU 2014-09)

The ~~new~~revenue recognition guidance did not have any effect on our financial condition, results of operations, or cash flows at the time of adoption. This is because the majority of our financial instruments and other contractual rights that generate revenue are covered by other GAAP, and therefore, were scoped out of this new guidance. Further, our prior method of recognizing service fee revenue was consistent with this new guidance. As a result, no cumulative effect adjustment to our opening balance of retained earnings in 2018 was required under the modified retrospective method.

Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (ASU 2017-07)

We are required to classify the service cost component of our net periodic pension and postretirement benefit costs as compensation costs. All other components of our net periodic pension and postretirement benefit costs are required to be classified as Noninterest expense - Other. Previously, our total net periodic pension and postretirement costs were classified as compensation costs. We made this classification change on a prospective rather than retrospective basis due to materiality. This classification guidance did not have a significant effect on our financial condition, results of operations, and cash flows.

Classification of Certain Cash Receipts and Cash Payments in the Statement of Cash Flows (ASU 2016-15)

We classify and disclose interest expense on zero coupon discount notes within operating activities, which is consistent with our prior and current classification practice. As a result, this guidance did have any effect on our financial condition, results of operations, and cash flows at the time of adoption.

Note 3 – Recently Issued but Not Yet Adopted Accounting Standards

~~Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost~~Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12)

In ~~March~~August of 2017, the FASB ~~amended~~issued targeted improvements to existing ~~GAAP~~derivatives and hedging guidance to ~~require the service cost component~~facilitate financial reporting that more closely reflects an entity’s risk management activities. We plan to adopt this guidance as of our net periodic pension and postretirement benefit costs to be classified as compensation costs. The other components of our net periodic pension and postretirement benefit costs are required to be classified as Noninterest expense - Other operating expenses on a retrospective basis effective January 1, ~~2018. Currently, our total net periodic pension and postretirement costs~~2019. We are ~~classified as compensation costs. We do not expect~~in the ~~classification guidance~~process of determining the expected effect of this ~~GAAP amendment will have a significant effect~~guidance on our financial condition, results of operations, and cash flows. Outlined below are the significant changes to existing GAAP guidance that are relevant to us.

~~Classification of Certain~~ Cash ~~Receipts and Cash Payments in the Statement of Cash Flows~~Flow Hedges:

~~In August~~For a cash flow hedge of ~~2016,~~interest rate risk of a variable-rate financial instrument, we would be able to designate the ~~FASB issued statement of~~variability in cash flows ~~classification guidance governing certain~~attributable to the contractually specified interest rate as the hedged risk. By eliminating the concept of benchmark interest rates for hedges of variable-rate instruments under current GAAP, the amendments remove the requirement to designate only the overall variability in cash ~~receipts and~~flows as the hedged risk in a cash ~~payments.~~ flow hedge of a variable-rate instrument indexed to a non-benchmark interest rate.

The ~~new guidance becomes effective January 1, 2018 and will be applied retrospectively for each period~~entire change in fair value of the hedging instrument is recorded in AOCI. Reclassification from AOCI into our statements of income, including hedge ineffectiveness, will depend on whether a recognition event has occurred, such as the discontinuation of the hedge relationship.

Fair Value Hedges:

Permits hedged risk to be the changes in fair value based on the contractual coupon’s benchmark rate component determined at hedge inception on the hedged item. Only the hedged risk of changes in fair value based on the full contractual coupon cash flows ~~are~~is permitted under existing GAAP.

Permits hedged risk to be partial-term of the hedged item, which only includes the designated cash flows being hedged.

Permits hedged risk to be a closed portfolio of prepayable financial assets or one or more beneficial interests secured by a portfolio of prepayable financial instruments in conjunction with a partial-term hedge election. The designated hedged item must have at least one asset or beneficial interest that will be outstanding at the end of the partial-term hedge election -that is, at least one asset or beneficial interest is not expected to be affected by prepayments, defaults, and other factors affecting the timing and amount of cash flows. This designation is referred to as the last-of-layer-method.

Cash Flow Hedges and Fair Value Hedges:

Requires both the effective and ineffective portion of a hedging relationship to be presented in either interest income or interest expense, whichever is appropriate. As a result, ineffectiveness related to hedging relationships would no longer be presented in derivatives and hedging activities.

Enables applying the long-haul method of assessing hedge effectiveness in cases where the shortcut method was initially applied but subsequently becomes no longer appropriate. This is provided only if we documented at hedge inception which long-haul methodology we would use in the event the shortcut method is discontinued.

Enables hedge effectiveness to be qualitatively assessed at the time of ~~adoption. The~~adoption for existing hedge relationships and for new ~~guidance~~hedge relationships entered into after adoption subsequent to their hedge inception in cases where initial quantitative testing is required. Such qualitative assessments would require us to quarterly verify and document that the facts and circumstances underlying the hedging relationship have not ~~expected~~changed since hedge inception.

Transition:

Upon adoption, the modified retrospective method will be applied. This means all cumulative-effect adjustments, which includes eliminating the separate measurement of ineffectiveness to ~~have any effect on our financial condition, results~~AOCI, will be recognized to the opening balance of ~~operations, and cash flows since our existing practice is consistent~~retained earnings as of the beginning of January 1, 2019.

Permits us to modify the risk being hedged without de-designation of the fair value hedging relationship. Such a modification will require us to recognize a cumulative-effect adjustment. We also may elect to de-designate a portion of the modified hedged item. In such cases, we reverse the portion of the cumulative basis adjustment related to the hedged item de-designated cumulative basis adjustment with the ~~provisions that are applicable to us. The provisions applicable to us are outlined below.~~offsetting entry recognized as a cumulative effect adjustment.

Measurement of Credit Losses on Financial Instruments (ASU 2016-13)

In June of 2016, the FASB amended existing GAAP guidance applicable to measuring credit losses on financial instruments. ~~The amendments are expected to result in recognizing credit losses in~~Specifically, the ~~financial statements on a timelier basis by utilizing forward looking information. Key provisions of the amendments relevant to us are outlined below.~~

~~Replaces~~amendment replaces the “incurred loss” impairment methodology applied under current GAAP with an “expected credit losses” methodology.

The expected credit losses methodology requires us to estimate all credit losses on financial instruments carried on an amortized cost basis and off-balance-sheet credit exposures over their contractual term. On balance sheet financial instruments include, but are not limited to, advances, MPF Loans held in portfolio, and ~~Held-to-maturity~~held-to-maturity (HTM) securities. Off-balance-sheet credit exposure refers to unfunded credit exposures, such as standby letters of credit.

The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the financial instrument’s reported amount. Accordingly, the amendment is expected to result in recognizing credit losses in the financial statements on a timelier basis by utilizing forward looking information.

In addition, the accounting for securities is amended as follows:

Aligns the income statement recognition of credit losses for securities with the reporting period in which changes in collectability occur by recording credit losses (and subsequent reversals) through an allowance rather than a write-down as currently required under GAAP.

Requires recognition of a credit loss on available-for-sale (AFS) securities into the income statement if the present value of cash flows expected to be collected on the security is less than its amortized cost basis. Additionally, the allowance on AFS debt securities will be limited to the amount by which fair value is less than the amortized cost basis.

Expands upon the current credit quality disclosures by requiring further disaggregation of financial instruments by their year of origination. This disclosure is expected to help financial statement users better understand credit quality trends of asset portfolios.

The ~~amendments become effective~~new guidance takes effect January 1, ~~2020, with early~~2020. Upon adoption, ~~permitted effective January 1, 2019. We plan~~any difference in the credit loss amount attributable to ~~implement~~both our on balance sheet and off balance sheet financial instruments resulting from applying the expected credit loss methodology ~~through~~compared to our existing incurred loss methodology will be recognized as a cumulative-effect adjustment to our ~~beginning~~January 1, 2020 opening retained earnings as of the first reporting period in which the new guidance becomes effective for us. The cumulative effect adjustment will equal the amount required to adjust our existing allowance for credit losses for our on balance-sheet financial instruments and other

~~liabilities for our off-balance sheet financial instruments to the amounts determined under the expected credit losses methodology.~~balance. A prospective transition approach is required for debt securities. Accordingly, any OTTI write-downs on securities ~~in which an other-than-temporary-impairment (OTTI) impairment had been recognized before our effective date. The accounting implications of such an approach are outlined below:~~

~~Write-downs~~ recognized prior to ~~our effective date on securities~~January 1, 2020 may not be reversed at the time of our adoption.

Improvements in expected cash flows ~~subsequent to adoption~~ for ~~such~~these securities will continue to be accounted for as yield adjustments over their remaining life.

~~Recoveries of amounts previously written off prior to the date of adoption~~ Additionally, recoveries for these securities will be recorded in earnings only when received.

We are in the process of reviewing the expected effect of this guidance on our financial condition, results of operations, and cash flows.

Leases (ASU 2016-02)

In February of 2016, the FASB issued new ~~guidance pertaining to~~ lease ~~accounting.~~accounting guidance. A modified retrospective transition approach will be utilized at the time of adoption, which is January 1, 2019. The new guidance requires us to recognize operating leases and right-to-use assets with terms exceeding 12 months, if any, in our statements of ~~condition if their term exceeds 12 months. Currently, we~~condition. Our existing practice is to recognize ~~our~~ operating leases off-balance sheet. The ~~new guidance becomes effective January 1, 2019. A modified retrospective transition approach is required~~expense related to our lease payments and the interest expense on our lease obligations will continue to be ~~applied to leases existing at, or entered into after, January 1, 2018.~~included in a single line item in our statements of income. We do not expect the new guidance to have a significant effect on our financial condition, results of operations, and cash flows since our existing off-balance sheet operating leases are not material.

~~Recognition and Measurement of Financial Assets and Financial Liabilities~~

In January of 2016, the FASB issued new guidance governing recognition and measurement of financial assets and financial liabilities. The new guidance becomes effective January 1, 2018. We do not expect the new guidance to have a significant effect on our financial condition, results of operations, and cash flows. The key provisions applicable to us are as follows:

~~The ability to elect the fair value option will continue to be permitted.~~

The portion of instrument-specific credit risk attributable to the total change in fair value of our consolidated obligations that are carried at fair value under the fair value option should be recognized in other comprehensive income. We will measure such instrument-specific credit risk based on our nonperformance risk. Specifically, our nonperformance risk includes our own credit risk and the credit risk associated with the joint and several liability of other FHLBs. We do not expect this requirement will have a material effect on our financial condition, results of operations, and cash flows.

The requirement to separately present financial assets and financial liabilities by measurement category, such as amortized cost, and form, such as securities or loans, on our statements of condition or the accompanying notes to the financial statements.

~~Revenue from Contracts with Customers~~

In May of 2014, the FASB issued new guidance governing revenue recognition from contracts with customers. Subsequently the FASB issued several other related pronouncements that provide additional revenue recognition guidance and clarifications to the original guidance issued in 2014. The new guidance becomes effective January 1, 2018. We do not expect the new revenue recognition guidance will have any effect on our financial condition, results of operations, or cash flows at the time of adoption. This is because the majority of our financial instruments and other contractual rights that generate revenue are covered by other GAAP, and therefore, are scoped out of this new guidance. Further, we believe that recognition of our service fee revenue, which is insignificant, is consistent with this new guidance.

Other-Than-Temporary Impairment Analysis

We recognized no OTTI charges on HTM or AFS securities for the periods presented. This is because we do not intend to sell these securities, we believe it is more likely than not that we will not be required to sell them prior to recovering their amortized cost basis, and we expect to recover the entire amortized cost basis. For further detail on our accounting policy regarding OTTI please see Note 2 - Summary of Significant Accounting Policies to the financial statements in our ~~2016~~2017 Form 10-K.

As of ~~June 30, 2017,~~March 31, 2018, we had a base case short-term housing price forecast for all markets with projected changes ranging from ~~-5.0%~~-7.0% to ~~+11.0%~~+12.0% over the twelve month period beginning ~~April~~January 1, ~~2017.~~2018. For the vast majority of markets, the short-term forecast has changes ranging from +1.0% to +6.0%.

Note 6 – Advances

We offer a wide range of fixed- and variable-rate advance products with different maturities, interest rates, payment characteristics and optionality.

The following table presents our advances by terms of contractual maturity. Actual maturities may differ from contractual maturities because some borrowers have the right to call or prepay advances with or without penalties.

Note 8 – Allowance for Credit Losses

See Note 2 - Summary of Significant Accounting Policies to the financial statements in our ~~2016~~2017 Form 10-K for further details regarding our allowance for credit losses methodology for each of the portfolio segments discussed below.

We have identified our portfolio segments as shown below:

Member credit products (advances, letters of credit and other extensions of credit to borrowers);

Conventional MPF Loans held in portfolio;

Government Loans held in portfolio; and

Federal Funds Sold and Securities Purchased Under Agreements to Resell.

Member Credit Products

We have not recorded any allowance for credit losses for our member credit products portfolio segment based upon our credit analysis and the repayment history on member credit products. We had no member credit products that were past due, on nonaccrual status, involved in a troubled debt restructuring or otherwise considered impaired. We have not recorded a separate liability to reflect credit losses on our member credit products with off-balance sheet credit exposure.

Conventional MPF Loans Held in Portfolio

For further detail of our MPF Risk Sharing Structure see page ~~F-15~~F-16 in our ~~2016~~2017 Form 10-K. There has been no material activity in our allowance for credit losses since December 31, ~~2016.~~2017.

Government Loans Held in Portfolio

Servicers are responsible for absorbing any losses incurred on Government Loans held in portfolio that are not recovered from the government insurer or guarantor. We did not establish an allowance for credit losses on our Government Loans held in portfolio for the reporting periods presented based on our assessment that our servicers have the ability to absorb such losses. Further, Government Loans were not placed on nonaccrual status or disclosed as troubled debt restructurings for the same reason.

Credit Quality Indicators - MPF Loans Held in Portfolio

The following table summarizes our recorded investment in MPF Loans by our key credit quality indicators, which include:

"Serious delinquency rate" consists of MPF Loans that are 90 days or more past due or in the process of foreclosure, as a percentage of the total recorded investment. MPF Loans that are both 90 days or more past due and in the process of foreclosure are only included once in our serious delinquency rate calculation.

"Past due 90 days or more still accruing interest" consists of MPF Loans that are either insured or guaranteed by the government or conventional mortgage loans that are well secured (by collateral that have a realizable value sufficient to discharge the debt or by the guarantee or insurance, such as primary mortgage insurance, of a financially responsible party) and in the process of collection.

Term Federal Funds Sold and Term Securities Purchased Under Agreements to Resell

We only held overnight Federal Funds sold and Securities Purchased Under Agreements to Resell as of ~~June 30, 2017,~~March 31, 2018, and December 31, ~~2016.~~2017. We did not have any longer term Federal Funds sold and Securities Purchased Under Agreements to Resell arrangements. We did not establish an allowance for credit losses for our overnight Federal Funds sold since all Federal Funds sold were repaid according to their contractual terms. We also did not establish an allowance for credit losses for overnight securities purchased under agreements to resell since all payments due under the contractual terms have been received and we hold sufficient underlying collateral.

Note 9 – Derivatives and Hedging Activities

~~See~~Refer to Note 2 - Summary of Significant Accounting Policies in our ~~2016~~2017 Form 10-K for our accounting policies for derivatives.

We transact most of our derivatives with large banks and major broker-dealers. Some of these banks and broker-dealers or their affiliates buy, sell, and distribute consolidated obligations. We are not a derivatives dealer and do not trade derivatives for speculative purposes. We enter into derivative transactions through either of the following:

A bilateral agreement with an individual counterparty for over-the-counter derivative transactions.

Clearinghouses classified as ~~DCOs~~Derivatives Clearing Organizations (DCOs) through ~~FCMs,~~Futures Commission Merchants (FCMs), which are clearing members of the DCOs, for cleared derivative transactions.

Managing Interest Rate Risk

We use fair value hedges to offset changes in the fair value or a benchmark interest rate (e.g., LIBOR) related to (1) a recognized asset or liability or (2) an unrecognized firm commitment. We use cash flow hedges to offset an exposure to variability in expected future cash flows associated with an existing recognized asset or liability or a forecasted transaction. We use economic hedges in cases where hedge accounting treatment is not permitted or achievable; for example, hedges of portfolio interest rate risk or financial instruments carried at fair value under the fair value option.

Managing Credit Risk on Derivative Agreements

Over-the-counter (bilateral) Derivative Transactions: We are subject to credit risk due to the risk of nonperformance by counterparties to our derivative agreements. For bilateral derivative agreements, the degree of counterparty risk depends on the extent to which master netting arrangements, collateral requirements and other credit enhancements are included in such contracts to mitigate the risk. We manage counterparty credit risk through credit analysis, collateral requirements and adherence to the requirements set forth in our policies and FHFA regulations. We require collateral agreements on all over-the-counter derivatives. Additionally, collateral related to over-the-counter derivatives with member institutions includes collateral assigned to us, as evidenced by a written security agreement, and which may be held by the member institution for our benefit. Based on credit analyses and collateral requirements, we do not anticipate any credit losses on our over-the-counter derivative agreements. See Note ~~13 - Fair Value~~ ~~to the financial statements in this Form 10-Q and~~ ~~Note~~ 16 - Fair Value in our ~~2016~~2017 Form 10-K for discussion regarding our fair value methodology for over-the-counter derivative assets and liabilities, including an evaluation of the potential for the fair value of these instruments to be affected by counterparty credit risk.

For ~~most~~nearly all of our bilateral derivative transactions executed prior to March 1, 2017, and for all transactions entered into after March 1, 2017, our bilateral derivative agreements are fully collateralized with a zero unsecured threshold in accordance with variation margin requirements issued by the U.S. federal bank regulatory agencies and the CFTC, as discussed in the Legislative and Regulatory Developments in the Bank’s Annual Report on Form 10-K for the year ended December 31, 2015. Certain of our bilateral derivative agreements may contain provisions that require us to post additional collateral with our counterparties forCommodity Futures Trading Commission (CFTC). For certain transactions executed prior to March 1, 2017, we may be required to post net additional collateral with our counterparties if there is deterioration in our credit rating. If our credit rating is lowered by a major credit rating agency, such as Standard and Poor's or Moody’s, we would be required to deliver additional collateral on derivatives in net liability positions. If our credit rating had been lowered from its current rating to the next lower rating ~~at June 30, 2017, no material~~by a major credit rating agency, such as Standard and Poor's or Moody’s, the amount of ~~additional~~ collateral we would have been required to ~~be delivered to our derivatives counterparties.~~deliver would not have been material at March 31, 2018.

Cleared Derivative Transactions: Cleared derivative transactions are subject to variation and initial margin requirements established by the DCO and its clearing members. As a result of rule changes adopted by our DCOs, variation margin payments are characterized as settlement of a derivative’s mark-to-market exposure and not as collateral against the derivative’s mark-to-market exposure. See Note 1 - Background and Basis of Presentation and Note 2 - Summary of Significant Accounting Policies for further discussion. We post our initial margin collateral payments and make variation margin settlement payments through our FCMs, on behalf of the DCO, which could expose us to institutional credit risk in the event that the FCMs or the DCO fail to meet their obligations. Clearing derivatives through a DCO mitigates counterparty credit risk exposure because the DCO is substituted for individual counterparties and variation margin settlement payments are made daily through the FCMs for changes in the value of cleared derivatives. The DCO determines initial margin requirements for cleared derivatives. In this regard, we pledged ~~$76~~$64 million of investment securities that can be sold or repledged, as part of our initial margin related to cleared derivative transactions at ~~June 30, 2017.~~March 31, 2018. Additionally, an FCM may require additional initial margin to be posted based on credit considerations, including but not limited to, if our credit rating downgrades. We had no requirement to post additional initial margin by our FCMs at ~~June 30, 2017.~~March 31, 2018.

Cash Flow Hedges

We are exposed to the variability in the total net proceeds received from forecasted zero-coupon discount note issuances, which is attributable to changes in the benchmark interest rate, London Interbank Offering Rate ("LIBOR"). As a result, we enter into cash flow hedge relationships utilizing derivative agreements to hedge the total net proceeds received from our "rolling" forecasted zero-coupon discount note issuances attributable to changes in LIBOR. The maximum length of time over which we are hedging this exposure is 3 years. We reclassify amounts in AOCI into our statements of income in the same periods during which the hedged forecasted transaction affects our earnings. We had no discontinued ~~hedges.~~hedges for the periods presented. The deferred net gains (losses) on derivative instruments in AOCI that are expected to be reclassified to earnings during the next twelve months were ~~$(4) million~~not material as of ~~June 30, 2017. The maximum length of time over which we are hedging our exposure to the variability in future cash flows for forecasted transactions is 3 years.~~March 31, 2018.

Note 10 – Consolidated Obligations

The FHLBs issue consolidated obligations through the Office of Finance as their agent. Consolidated obligations consist of discount notes and consolidated obligation bonds. Consolidated discount notes are issued to raise short-term funds, are issued at less than their face amount and redeemed at par value when they mature. The maturity of consolidated obligation bonds may range from less than one year to over 20 years, but they are not subject to any statutory or regulatory limits on maturity.

The following table presents our consolidated obligation discount notes for which we are the primary obligor. All are due in one year or less.

Note 11 – Capital and Mandatorily Redeemable Capital Stock (MRCS)

Under our Capital Plan our stock consists of two sub-classes of stock, Class B1 activity stock and Class B2 membership stock (together, Class B stock), both with a par value of $100 and redeemable on five years' written notice, subject to certain conditions. Under the Capital Plan, each member is required to own capital stock in an amount equal to the greater of a membership stock requirement or an activity stock requirement. Class B1 activity stock is available to support a member's activity stock requirement. Class B2 membership stock is available to support a member's membership stock requirement and any activity stock requirement.

Minimum Capital Requirements

For details on our minimum capital requirements, including how the ratios below were calculated, see Minimum Capital Requirements on page ~~F-43~~F-44 of our ~~2016~~2017 Form 10-K. We complied with our minimum regulatory capital requirements as shown below.

Repurchase of Excess Capital Stock

~~On January 26,~~Beginning in 2017, we began repurchasing all excess Class B2 membership stock on a weekly basis at par value, i.e., at $100 per share. Members may continue to request repurchase of excess stock on any business day in addition to the weekly repurchase. All repurchases of excess stock, including automatic weekly repurchases, will continue until otherwise announced, but remain subject to our regulatory requirements, certain financial and capital thresholds, and prudent business practices. ~~Repurchase of excess capital stock held by members is subject to compliance with financial and capital thresholds, as detailed on page 57 of our 2016 Form 10-K.~~

~~As of June 30, 2017, our regulatory capital stock outstanding was $1.8 billion, a net decrease of $183 million from year-end, due in part to these automatic weekly repurchases.~~

Note 13 - Fair Value

~~Fair value represents the exit price that we would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date.

The following ~~tables are~~table is a summary of the fair value estimates and related levels in the ~~fair value~~ hierarchy. The carrying amounts are ~~as recorded in~~per the statements of condition. ~~These tables~~Fair value estimates represent the exit prices that we would receive to sell assets or pay to transfer liabilities in an orderly transaction with market participants at the measurement date. They do not represent an estimate of our overall market value as a going concern, as they do not take into account future business opportunities ~~and future net~~or profitability of assets and liabilities.

Fair Value Option

We may elect the fair value option for financial instruments, such as advances, MPF Loans held for sale, and consolidated obligation discount notes and bonds, in cases where hedge accounting treatment may not be achieved due to the inability to meet the hedge effectiveness testing criterion. Financial instruments for which we elected the fair value option along with their related fair value are shown on our Statements of Condition. Refer to our Note 2 – Summary of Significant Accounting Policies to the financial statements in our ~~2016~~2017 Form 10-K for further details.

The following table presents the changes in fair values of financial assets and liabilities carried at fair value under the fair value option. These changes were recognized in noninterest income - instruments held under the fair value option in our statements of income.

Summary and Outlook

First Quarter 2018 Dividend

On ~~July 27, 2017,~~April 24, 2018, the ~~Bank's~~Bank’s Board of Directors increased the dividend declared per share on both sub-classes of capital stock. Based on the Bank’s preliminary financial results for the ~~second~~first quarter of ~~2017,~~2018, the Board of Directors declared a dividend of ~~3.30%~~4.00% (annualized) for Class B1 activity capital stock (an increase of 1550 basis ~~points)~~points from the previous quarter) and a dividend of ~~1.25%~~1.60% (annualized) for Class B2 membership capital stock (an increase of 2010 basis ~~points)~~points from the previous quarter).

The Bank pays a higher dividend per share on Class B1 activity stock than on Class B2 ~~capital~~membership stock to reward members who use the Bank’s advances and, thereby, support the financial health of the entire cooperative.

Results of Operations

Net Interest Income

Net interest income is the difference between the amount we recognize into interest income on our interest earning assets and the amount we recognize into interest expense on our interest bearing liabilities. These amounts were determined in accordance with GAAP and were based on the underlying contractual interest rate terms of our interest earning assets and interest bearing liabilities as well as the following items:

Net interest paid or received on interest rate swaps that are accounted for as fair value or cash flow hedges;

Amortization of premiums;

Accretion of ~~discounts and~~ discounts;

OTTI ~~reversals;~~security yield adjustments due to either subsequent increases or decreases in estimated cash flows;

Amortization of hedge adjustments;

Advance and investment prepayment fees; and

MPF credit enhancement fees.

The table on the following page presents the increase or decrease in interest income and expense due to volume or rate variances. The calculation of these components includes the following considerations:

•

Average Balance: Average balances are calculated using daily balances. ~~Historical~~Amortized cost ~~balances are~~basis is used to compute the average balances for most of our financial instruments, including ~~available for sale securities and~~ MPF Loans held in portfolio that are on nonaccrual ~~status.~~status and available for sale securities. The calculation of the yield on our available for sale securities does not give effect to changes in fair value that are reflected as a component of accumulated other comprehensive income (AOCI). Fair value is used to compute average balances for our trading securities and financial instruments carried at fair value under the fair value option.


•	Total Interest: Total interest includes ~~all components of~~the net interest income ~~if applicable,~~components, as discussed ~~above.~~above, applicable to our interest earning assets and interest bearing liabilities.


•	Yield/Rate: Effective yields/rates are based on total interest and average ~~daily~~ balances ~~and include all components of net interest income~~ as ~~discussed~~defined above. Yields/rates are calculated on an annualized basis.

Any changes due to the combined volume/rate variance have been allocated ~~ratably~~ to ~~volume and rate.~~volume.

Interest income from investment securities declined ~~during the first six months of 2017~~ as ~~we recognized fewer investment prepayment fees, and experienced the continued reduction in average investment balances as securities~~MBS/ABS matured or paid ~~down. We expect the decline~~down and we did not make new investments in ~~average balances and related interest income to continue in the near term due to~~MBS/ABS under FHFA regulatory limits ~~on the amount of investment securities that we may hold on our balance sheet~~ as discussed in Investments ~~starting~~ on page 1210 in our ~~2016~~2017 Form ~~10-K.~~10-K. One of the limits is that our investment in MBS/ABS cannot exceed three times our total regulatory capital. We expect to resume making MBS and ABS investments sometime in 2018, subject to regulatory limitations.

Interest income from advances increased primarily due to a rise in interest rates, ~~and, to a lesser extent, higher member demand for advances. Higher interest rates~~which resulted primarily from rate hikes by the Federal Reserve ~~Bank.~~Bank during 2017. Interest income also increased to a lesser extent as a result of higher member demand for advances.

Interest income from MPF Loans held in portfolio ~~declined slightly~~was essentially unchanged from 2017.

Interest income from Federal Funds sold and securities purchased under agreements to resell increased both due to ~~lower average~~higher volumes outstanding and increases in interest rates by the Federal Reserve Bank. We increased the amounts of these liquid assets as demand for our ~~more seasoned~~advances and ~~higher~~letters of credit increased.

Interest expense on both our shorter termed consolidated obligation discount notes and our longer termed consolidated obligation bonds increased primarily due to rising short and long term interest ~~rate MPF Loans mature~~rates, and ~~are replaced with lower interest rate MPF Loans.~~to a lesser extent, an increase in notes and bonds outstanding.

Interest income from Federal Funds sold and securities sold under agreements to repurchase increased primarily due to higher volume outstanding year over year. The increase in interest income also was due to rate hikes by the Federal Reserve Bank.

Interest expense on our consolidated obligation discount notes increased due to rising short term interest rates despite a significant decline in average balances outstanding as we shifted a portion of our funding to longer term bonds. Interest rates on our longer term bonds declined; a result of money market reforms which increased demand for FHLB debt in the market which improved our funding costs.

MPF fees (including from other FHLBs)

A majority of MPF fees are from other FHLBs that pay us a fixed membership fee to participate in the MPF Program and a volume based fee for us to provide services related to their on balance sheet MPF Loans. MPF fees also include income from off-balance sheet MPF Loan products and other related transaction fees. These fees offset a portion of the expenses we incur to administer the program. MPF fees have grown as off balance sheet MPF Loan volume increased during the periods presented.

Other, net

Other, net consists primarily of fee income we earn from member standby letters of credit products, as noted in Item 2. Selected Financial Data.

Cash and due from banks, interest bearing deposits, Federal Funds sold, and securities purchased under agreements to resell

Amounts held in these accounts will vary each day based on the following:

Interest rate spreads between Federal Funds sold and securities purchased under agreements to resell and our debt;

Liquidity requirements;

Counterparties available; and

Collateral availability on securities purchased under agreements to resell.

We increased the amounts of these liquid assets as demand for our advances and letters of credit increased.

Investment Securities

~~We are currently unable to make additional investments~~Investment securities increased as we purchased $2.6 billion in short term U.S. Government securities during the first quarter of 2018. This increase was partially offset by declines in MBS/ABS ~~under FHFA regulatory limits~~securities that matured or paid down and were not replaced, as ~~discussed~~noted in ~~Investments~~Results of Operations on page ~~12 in our 2016 Form 10-K.~~40.

Advances

Advances increased to the highest outstanding ~~quarter-end~~quarter end balance in our history ~~at June 30, 2017. See~~ ~~Note 6 - Advances~~due to ~~the financial statements.~~

strong market demand for funding in our district. While advance demand is strong, it is possible that member demand for our advances could decline in future periods should their funding needs change, or to the extent they elect alternative funding resources. In addition, as our advances with captive insurance companies mature, our total advance levels ~~could~~may decrease.

MPF Loans Held in Portfolio, Net of Allowance for Credit Losses

We had a small net ~~decrease~~increase in our outstanding MPF Loans from prior year end, as our purchases of new loans ~~during 2017 mostly~~ offset maturities and paydowns experienced in our MPF Loan portfolio.

In addition to our MPF Loans held in portfolio, we have MPF off-balance sheet products, where we buy and concurrently resell MPF Loans to Fannie Mae or other third party investors or pool and securitize them into Ginnie Mae MBS.

Liquidity, Funding, & Capital Resources

Liquidity

For the period ending ~~June 30, 2017,~~March 31, 2018, we ~~have~~ maintained a liquidity position in accordance with FHFA regulations and guidance, and policies established by our Board of Directors. Based upon our excess liquidity position described below, we anticipate remaining in compliance with our liquidity requirements. See Liquidity, Funding, & Capital Resources on page 48 in our ~~2016~~2017 Form 10-K for a detailed description of our liquidity requirements. We use different measures of liquidity as follows:

Overnight Liquidity – Our policy requires us to maintain overnight liquid assets at least equal to 3.5% or ~~$2.9~~$3.2 billion of total assets. As of ~~June 30, 2017,~~March 31, 2018, our overnight liquidity was ~~$16.0~~$24.0 billion or ~~20%~~26% of total assets, giving us an excess overnight liquidity of ~~$13.2~~$20.8 billion.

Deposit Coverage – To support our member deposits, FHFA regulations require us to have an amount equal to the current deposits invested in obligations of the U.S. Government, deposits in eligible banks or trust companies, or advances with maturities not exceeding five years. As of ~~June 30, 2017,~~March 31, 2018, we had excess liquidity of ~~$38.2~~$49.6 billion to support member deposits.

Contingency Liquidity – The cumulative five business day liquidity measurement assumes there is a localized credit crisis for all FHLBs where the FHLBs do not have the ability to issue new consolidated obligations or borrow unsecured funds from other sources (e.g., purchasing Federal Funds or customer deposits). Our net liquidity in excess of our total uses and reserves over a cumulative five-business-day period was ~~$16.3~~$16.9 billion as of ~~June 30, 2017.~~March 31, 2018.

In addition to the liquidity measures discussed above, FHFA guidance requires us to maintain daily liquidity through short-term investments in an amount at least equal to our anticipated cash outflows under two different scenarios. One scenario assumes that we cannot access the capital markets for 15 days and that during that time members do not renew any maturing, prepaid, and called advances. The second scenario assumes that we cannot access the capital markets for 5five days and that during that period we will automatically renew maturing and called advances for all members except for very large, highly rated members. These additional requirements are more stringent than the contingency liquidity requirement discussed above and are designed to enhance our protection against temporary disruptions in access to the FHLB debt markets in response to a rise in capital markets volatility. As a result of this guidance, we are maintaining increased balances in short-term investments. In addition, we fund certain overnight or shorter-term investments and advances with debt that has a maturity that extends beyond the maturities of the related investments or advances. For a discussion of how this may impact our earnings, see page 2118 in the Risk Factors section of our ~~2016~~2017 Form 10-K. OnIn July ~~3, 2017,~~ the FHFA proposed to rescind certain minimum regulatory liquidity requirements for the FHLBs as further discussed in Legislative and Regulatory Developments on page ~~55.~~14 in our 2017 Form 10-K.

We are sensitive to maintaining an appropriate liquidity and funding balance between our financial assets and liabilities, and we measure and monitor the risk of refunding such assets as liabilities mature (refunding risk). In measuring the level of assets requiring refunding, we take into account their contractual maturities, as further described in the notes to the financial statements. In addition, we make certain assumptions about their expected cash flows. These assumptions include: calls for assets with such features, projected prepayments and scheduled amortizations for our MPF Loans held in portfolio, MBS and ABS investments. The following table presents the unpaid principal balances of (1) MPF Loans held in portfolio, (2) AFS securities, and (3) HTM securities (including ABS and MBS investments), by expected principal cash flows. The table is illustrative of our assumptions about the expected rather than contractual cash ~~flow~~flows of our assets, including prepayments made in advance of maturity.

We consider our liabilities available to fund assets until their contractual maturity. For further discussion of the liquidity risks related to our access to funding, see page 2422 of the Risk Factors section in our ~~2016~~2017 Form 10-K.

Our operating assets and liabilities support our mission to provide our member shareholders competitively priced funding, a reasonable return on their investment in our capital stock, and support for community investment activities. Operating assets and liabilities can vary significantly in the normal course of business due to the amount and timing of cash flows, which are affected by member-driven activities and market conditions. We believe cash flows from operations, available cash balances and our ability to generate cash through short- and long-term borrowings are sufficient to fund our operating liquidity needs. The ~~change of $233 million~~decline in net cash provided by ~~(used in)~~ operating activities resulted primarily ~~resulted~~ from ~~the non-cash~~a noncash adjustment ~~attributable~~related to ~~the unrealized net changes in the fair value of our derivative instruments.~~derivatives and hedging activities.

Capital Resources

Capital Rules

Under ~~our~~the Second Amended and Restated Capital Plan of the Federal Home Loan Bank of Chicago, effective October 1, 2015 (Capital Plan), our stock consists of two sub-classes of stock, Class B1 activity stock and Class B2 membership stock (together, Class B stock), both with a par value of $100 and redeemable on five years' written notice, subject to certain conditions. Each member is required to own capital stock in an amount equal to the greater of a membership stock requirement or an activity stock requirement. Class B1 activity stock is available ~~for purchase only~~ to support a member's activity stock requirement. Class B2 membership stock is available ~~to be purchased~~ to support a member's membership stock requirement and any activity stock requirement.

Under our Capital Plan, our Board of Directors may set a threshold of between $10,000 and $75 million on the amount of Class B2 membership stock that would otherwise be held for membership if a member has advances outstanding that have an activity stock requirement in excess of the threshold amount. In that case, the amount of Class B2 membership stock that exceeds such threshold and is necessary to support advance activity is automatically converted into Class B1 activity stock. That threshold is currently set at $10,000, which means that we will convert to Class B1 activity capital stock any capital stock supporting advances that exceeds the lesser of the member's membership requirement or $10,000.

The Board of Directors may periodically adjust members' activity stock requirement for certain new advances within a range of 2% and 6% of a member's outstanding advances. Our Board implemented this provision through ~~RCAP~~the Reduced Capitalization Advance Program (RCAP) as further discussed below. Each member’s activity stock requirement ~~remained~~remains at 4.5% for non-RCAP advances.

Our Capital Plan allows for an activity stock requirement for MPF Loans acquired for our portfolio within a range of 0% and 6%, which our Board has set at 0%. Should the Board decide to introduce this capital requirement, we intend to notify members sufficiently in advance of the change and apply that change only to future acquisitions.

The Board may periodically adjust members’ membership stock requirement within a range of 0.20% to 2% of a member’s mortgage assets. Each member’s membership stock requirement is the greater of either $10,000 or 0.40% of a member's mortgage assets. A member’s investment in membership stock is subject to a cap equal to the lesser of (1) a dollar cap set by the Board within a range of $10,000 and $75 million, and (2) 9.9% of our total capital stock outstanding as of the prior December 31. The cap on each member’s membership stock requirement is now $5 million, which is less than 9.9% of the Bank’s total capital stock outstanding at December 31, ~~2016,~~2017, and is thus the operative cap during the remainder of ~~2017~~2018 unless the Board sets a new cap.

~~Table of Contents~~

~~(Dollars in tables in millions except per share amounts unless otherwise indicated)~~

Membership stock requirements will continue to be recalculated annually, whereas the activity stock requirement and any automatic conversion of Class B2 membership stock to Class B1 activity stock related to the threshold will apply on a daily basis.

~~For details on our capital stock requirement changes in 2016, see~~ ~~Capital Resource~~ ~~on page 54 of our 2016 Form 10-K.~~

We may only redeem or repurchase capital stock from a member if, following the redemption or repurchase, the member continues to meet its minimum investment requirement and we remain in compliance with our regulatory capital requirements as discussed in Note 11 - Capital and Mandatorily Redeemable Capital Stock (MRCS) to the financial statements in this Form 10-Q.

~~On July 3, 2017, the FHFA proposed to amend certain regulatory capital requirements for the FHLBs as further discussed in~~ ~~Legislative and Regulatory Developments~~ ~~on page 55.~~

Members that withdraw from membership must wait at least five years after their membership was terminated and all of their capital stock was redeemed or repurchased before being readmitted to membership in any FHLB.

For details on our capital stock requirements under our Capital Plan during 2017, see Capital Resource on page 53 of our 2017 Form 10-K. Under the terms of our Capital Plan, our Board of Directors is authorized to amend the Capital Plan, and the FHFA must approve all such amendments before they become effective.

For details on our minimum regulatory capital requirements see Note 11 - Capital and Mandatorily Redeemable Capital Stock (MRCS) to the financial statements in this Form 10-Q, and Minimum Capital Requirements on page F-44 of our 2017 Form 10-K.

Reduced Capitalization Advance Program

RCAP allows members to borrow one or more advances with an activity stock requirement of only 2% for the life of the advance instead of the 4.5% requirement under our Capital Plan’s general ~~provisions as further discussed in~~ ~~Capital Resources~~ ~~on page 54 of our 2016 Form 10-K.~~provisions. As of ~~June 30, 2017,~~March 31, 2018, and December 31, ~~2016,~~2017, RCAP advances outstanding total ~~$22.9~~$24.7 billion to ~~161~~157 members and ~~$22.7~~$24.7 billion to ~~147~~158 members, respectively.

Repurchase of Excess Capital Stock

~~On January 26,~~Beginning in 2017, we began repurchasing all excess Class B2 membership stock on a weekly basis at par value, i.e., $100 per ~~share~~share.. Members may continue to request repurchase of excess stock on any business day in addition to the weekly repurchase. All repurchases of excess stock, including automatic weekly repurchases, will continue until otherwise announced, but remain subject to our regulatory requirements, certain financial and capital thresholds, and prudent business ~~practices~~practices.

~~Repurchase of excess capital stock held by members is subject to compliance with~~For details on the financial and capital thresholds ~~as detailed~~ relating to repurchases, see Repurchase of Excess Capital Stock on page 57 of our ~~2016~~2017 Form 10-K.

Accumulated other comprehensive income (loss) in the above table consists of changes in market value of various balance sheet accounts where the change is not recorded in earnings but are instead recorded in equity capital as the income (loss) is not yet realized. For details on these changes please see Note 12 - Accumulated Other Comprehensive Income (Loss) to the financial statements.

Although we have had no OTTI year to date in ~~2017,~~2018, credit deterioration may negatively impact our remaining ~~private-label~~private label MBS portfolio. We cannot predict if or when impairments will occur, or the impact these impairments may have on our retained earnings and capital position. See ~~page 28 of~~ the Risk Factors section on page 16 of our ~~2016~~2017 Form 10-K.

We may not pay dividends if we fail to satisfy our minimum capital and liquidity requirements under the FHLB Act and FHFA regulations.

On ~~July 27, 2017,~~April 24, 2018, our Board of Directors ~~increased the dividend declared per share on both sub-classes of capital stock. The Board~~ declared a ~~3.30%~~4.00% dividend (annualized) for Class B1 activity stock ~~(an increase of 15 basis points)~~ and a ~~1.25%~~1.60% dividend (annualized) for Class B2 membership stock ~~(an increase of 20 basis points)~~ based on our preliminary financial results for the ~~second~~first quarter of ~~2017.~~2018. This dividend, including dividends on mandatorily redeemable capital stock, totaled ~~$11~~$16 million and ~~will be paid~~is scheduled for payment on ~~August~~May 15, ~~2017.~~2018. The Class B2 capital stock dividend is intended to enhance the value of membership; the Class B1 capital stock dividend reduces the effective cost of borrowing from the Bank and rewards our members who support the entire cooperative ~~through their advances.~~by using our advance products.

Although we continue to work to maintain our financial strength to support a reasonable dividend, any future dividend determination by our Board will be at our Board's sole discretion and will depend on future operating results, our Retained Earnings and Dividend Policy and any other factors the Board determines to be relevant. For further information see Retained Earnings & Dividends on page 57 in our ~~2016~~2017 Form 10-K.

We continue to allocate 20% of our net income each quarter to a restricted retained earnings account in accordance with the Joint Capital Enhancement Agreement that we entered into with the other FHLBs, as further discussed in Joint Capital Enhancement Agreement on page ~~F-44~~F-45 in our ~~2016~~2017 Form 10-K.

Risk Management - Credit Risk

Managing Our Credit Risk Exposure Related to Member Credit Products

Our credit risk rating system focuses primarily on our member's overall financial health and takes into account the member's asset quality, earnings, and capital position. For further information please see Member Credit Risk Ratings on page 6461 in our ~~2016~~2017 Form 10-K.

The following table presents the number of members and related credit outstanding to them by credit risk rating. Credit outstanding consists primarily of outstanding advances and letters of credit. MPF credit enhancement obligations, member derivative exposures, and other obligations make up the rest. Of the total credit outstanding, ~~$46.7~~$50.9 billion were advances (par value) and ~~$13.2~~$20.1 billion were letters of credit at ~~June 30, 2017,~~March 31, 2018, compared to ~~$45.0~~$48.0 billion and ~~$10.8~~$19.6 billion at December 31, ~~2016.~~2017.

MPF Loans and Related Exposures

For details on our allowance for credit losses on MPF Loans, please see Note 8 - Allowance for Credit Losses to the financial statements.

Credit Risk Exposure - Our credit risk exposure on conventional MPF Loans held in portfolio is the potential for ~~financial loss~~credit losses due to borrower default on contractual principal and interest, which would result from the depreciation in the value of the real estate collateral securing the MPF Loan, offset by our ability to recover losses from PMI, Recoverable CE Fees, and the CE Amount which may include SMI. The PFI is required to pledge collateral to secure any portion of its CE Amount that is a direct obligation of the PFI. For further details see

Loss Structure for Credit Risk Sharing Products on page 9 of our 2017 Form 10-K, and Credit Risk Exposure and Setting Credit Enhancement Levels - Credit losses in a Master Commitment are first absorbed by the Bank’s FLA but, if applicable to the MPF product, we will withhold a PFI’s scheduled performance credit enhancement fee in order to reimburse ourselves for any losses allocated to the FLA. If the FLA is exhausted, the credit losses are then absorbed by the PFI’s CE Amount that is calculated by utilizing a third party’s credit model. For further details on the FLA and PFI’s CE Amount, refer to ~~Item 1- PFI Responsibilities~~on page ~~9 and~~ ~~Note 2 - MPF Risk Sharing Structure~~ ~~on page F-15 of the 2016 10-K.~~

Pursuant to the revised AMA regulation, effective January 18, 2017, we adjusted our methodology to set the PFI’s CE Amount. The PFI’s CE Amount is determined by the Bank with respect to an asset or a pool, based on documented analysis, that the Bank has a high degree of confidence that it will not bear material losses beyond the losses absorbed by the FLA, even under reasonably likely adverse changes to expected economic conditions.

The CE Amounts and the FLA for certain conventional MPF products held in our portfolio may be periodically reset lower for each Master Commitment after a required period of seasoning because the amount of credit enhancement necessary to maintain our risk of credit losses within our risk tolerance is usually reduced over time.

~~Table of Contents~~

~~(Dollars in tables in millions except per share amounts unless otherwise indicated)~~

Under the MPF Plus product, the PFI is required to provide an SMI policy covering MPF Loans in the Master Commitment and having a deductible initially equal to the FLA. Certain SMI providers fell below the requirements in the MPF Guides and instead of replacing the SMI provider or indemnifying us for any losses, most PFIs elected to forfeit future performance CE Fees. Credit losses associated with Master Commitments where the SMI coverage has been discontinued are incorporated into the allowance for credit losses calculation. Such credit losses are immaterial.

~~The following table shows the status~~63 of our credit enhancement structure on conventional MPF Loans held in portfolio. Unpaid principal balances in this table include REO, as losses in REO impact, and are impacted by, the credit enhancement structure of a Master Commitment. As defined, the CE Amount includes SMI on the MPF Plus product. Government Loans are excluded from the table as they are not directly credit enhanced by the PFI.

Managing Our Credit Risk Exposure Related to Derivative Agreements

See Note 9 - Derivatives and Hedging Activities to the financial statements for a discussion of how we manage our credit risk exposure related to derivative agreements. We have credit exposure on net asset positions where we have not received adequate collateral from our counterparties. We also have credit exposure on net liability positions where we have pledged collateral in excess of our liability to a counterparty.

The following table presents our derivative positions where we have such credit exposures. The rating used was the lowest rating among the three largest ~~Nationally Recognized Statistical Rating Organizations.~~NRSROs. Non-cash collateral pledged consists of initial margin we posted through our FCMs, on behalf of the DCOs for cleared derivatives and is included in our derivative positions with credit exposure.

Legislative and Regulatory Developments

Significant regulatory actions and developments are summarized below.

2017 Wisconsin Act 340. On April 16, 2018, Wisconsin Governor Scott Walker signed into law the 2017 Wisconsin Act 340 which includes three provisions we believe will benefit the Bank and our Wisconsin members.

The first provision clarifies in the Wisconsin public deposit statute that FHLB ~~Capital Requirements~~letters of credit are acceptable collateral substitutes for public unit deposits. This clarification may help our Wisconsin bank and credit union members more easily obtain low-cost local funding.

The second provision provides protections for the Bank under state insurance insolvency law by limiting the stay authority applicable to the Bank and removing the Bank from the voidable preference provisions. These protections will allow our Wisconsin insurance company members to receive improved securities collateral values when borrowing from us.

The third provision allows the Wisconsin Department of Financial Institutions to share their confidential exam reports of state-chartered banks, thrifts, and credit unions with the Bank. Federal law has long required federal banking regulators to share their exam reports with the FHLBs. This provision will help our Wisconsin-chartered depository members receive similar collateral values as federally-chartered institutions when borrowing from us.

FHFA Proposed Amendments to Affording Housing Program ("AHP") Regulations. On ~~July 3, 2017,~~March 14, 2018, the FHFA published a proposed rule to ~~adopt, with amendments,~~amend the ~~regulations~~operating requirements of the ~~Federal Housing Finance Board (predecessor~~FHLBs’ AHP. The proposal is open for public comment through June 12, 2018. If adopted as proposed, among other updates, the AHP rule would:

require an FHLB to create its own scoring criteria that are designed to satisfy new regulatory outcome requirements, replacing the ~~FHFA) pertaining~~existing regulatory scoring guidelines;

permit an FHLB to voluntarily increase its AHP homeownership set-aside funding program to 40% of annual available funds (up from the ~~capital~~current rule’s 35% annual limit);

increase the per-household set-aside grant amount to $22,000 with an annual housing price inflation adjustment (up from the current fixed limit of $15,000);

remove the retention agreement requirement for owner-occupied units;

further align AHP monitoring with certain federal government funding programs;

increase threshold requirements for certain project types, such as projects dedicated to homeless or special needs populations; and

authorize an FHLB using market research empirical data to create special targeted grant programs that would be a sub-set of the ~~FHLBs.~~regular AHP competitive funding program.

The rule, as proposed, would represent a substantial overhaul of the existing regulation on the FHLBs’ AHP and fundamentally change the structure and methodology for awarding grants to affordable housing projects. The proposed rule would ~~carry over most~~also increase AHP’s complexity and administrative burden.

The rule, as proposed, would require changes in the areas of operations, communications, and information systems of the ~~existing regulations without~~FHLBs. It would also require increased Board and Affordable Housing Advisory Council action and increased communications and education with members and sponsors. We do not believe, the rule, if adopted substantially as proposed, would be material to our financial condition or results of operation, since, among other things, it would not increase the annual AHP funding requirement. However, we expect there will be increased costs related to implementing the rule requirements and making related adjustments to our systems. In addition, if the rule is adopted as proposed, the Bank expects a possible change ~~but would substantively revise~~to the ~~credit risk component~~types of projects that may be funded on a go-forward basis in the Bank’s district, with a commensurate impact on AHP sponsors and their respective communities.

Office of the ~~risk-based capital requirement, as well as~~Comptroller of the ~~limitations~~Currency ("OCC"), Federal Reserve Board ("FRB"), Federal Deposit Insurance Corporation ("FDIC"), Farm Credit Administration and FHFA Proposed Rule on ~~extensions~~Margin and Capital Requirements for Covered Swap Entities. On February 21, 2018, the OCC, FRB, FDIC, Farm Credit Administration, and the FHFA published a proposed amendment to each agency’s final rule on Margin and Capital Requirements for Covered Swap Entities (“Swap Margin Rules”) to conform the definition of ~~unsecured credit.~~“eligible master netting agreement” in such rules to the FRB’s, OCC’s and FDIC’s final qualified financial contract (“QFC”) rules. It also clarifies that a legacy swap would not be deemed to be a covered swap under the Swap Margin Rules if it is amended to conform to the QFC rules. The ~~main revisions would remove requirements that~~QFC rules previously published by the ~~FHLBs calculate credit risk capital charges~~OCC, FRB, and ~~unsecured credit limits based~~FDIC require their respective regulated entities to amend covered QFCs to limit a counterparty’s immediate termination or exercise of default rights in the event of bankruptcy or receivership of the regulated entity or its affiliate(s).

Comments on ~~ratings issued by a nationally recognized statistical rating organization, and instead require that the FHLBs establish and use their own internal rating methodology. With respect to derivatives,~~ the proposed rule would impose a new capital charge for cleared derivatives, which under the existing rule do not carry a capital charge, to align with the Dodd-Frank Act’s clearing mandate. The proposed rule also would revise the percentages used in the regulation’s tables to calculate credit risk capital charges for advances and for non-mortgage assets. The FHFA proposes to retain for now the percentages used in the tables to calculate capital charges for mortgage-related assets, and to address the methodology for residential mortgage assets at a later date. While a March 2009 regulatory directive pertaining to certain liquidity matters willwere due by April 23, 2018. We continue ~~to remain in place, the FHFA also proposes to rescind certain minimum regulatory liquidity requirements for the FHLBs and address these liquidity requirements in a separate rulemaking.~~

~~We are continuing~~ to evaluate the proposed rule, but do not expect this rule, if adopted ~~in final form, to materially affect our financial condition or results of operations. Comments on the~~substantially as proposed, ~~rule are due by September 1, 2017.~~

~~FHLB Membership for Non-Federally-Insured Credit Unions~~

On June 5, 2017, the FHFA issued a final rule effective July 5, 2017 governing FHLB membership that would implement statutory amendments to the Federal Home Loan Bank Act authorizing FHLBs to accept applications for membership from state-chartered credit unions without federal share insurance, provided that certain prerequisites have been met. The new rule generally treats these credit unions the same as other depository institutions with an additional requirement that they obtain: (1) an affirmative statement from their state regulator that they meet the requirements for federal insurance as of the date of their application for FHLB membership; (2) a written statement from the state regulator that it cannot or will not make any determination regarding eligibility for federal insurance; or (3) if the regulator fails or refuses to respond to the credit union’s request within six months, confirmation of the failure to receive a response.

~~We do not expect this rule~~ to materially affect our financial condition or results of operations.

~~Minority and Women Inclusion~~

On July 25, 2017, the FHFA published a final rule, effective August 24, 2017, amending its Minority and Women Inclusion regulations to clarify the scope of the FHLBs’ obligation to promote diversity and ensure inclusion. The final rule updates the existing FHFA regulations aimed at promoting diversity and the inclusion and use of minorities, women, and individuals with disabilities, and the businesses they own (MWDOB) in all FHLB business and activities, including management, employment, and contracting. The final rule will:

require the FHLBs to develop stand-alone diversity and inclusion strategic plans or incorporate diversity and inclusion into their existing strategic planning processes and adopt strategies for promoting diversity and ensuring inclusion;

~~encourage the FHLBs to expand contracting opportunities for minorities, women, and individuals with disabilities through subcontracting arrangements;~~

require the FHLBs to amend their policies on equal opportunity in employment and contracting by adding sexual orientation, gender identity, and status as a parent to the list of protected classifications;

~~require the FHLBs to develop policies that address reasonable accommodations for employees to observe their religious beliefs;~~

require the FHLBs to provide information in their annual reports to the FHFA about their efforts to advance diversity and inclusion through financial transactions, identification of ways in which FHLBs might be able to improve business with the FHLB by enhancing customer access by MWDOB businesses, including through the FHLB's affordable housing and community investment programs and strategies for promoting the diversity of supervisors and managers; and

~~require the FHLBs to classify and provide additional data in their annual reports about the number of, and amounts paid under, their contracts.~~

We do not expect this final rule to materially affect our financial condition or results of operations, but anticipate that it may result in increased compliance costs and substantially increase the amount of tracking, monitoring, and reporting that would be required of the Bank.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Our Asset/Liability Management Committee provides oversight of risk management practices and policies. This includes routine reporting to senior Bank management and the Board of Directors, as well as maintaining the Income and Market Value Risk Policy, which defines our interest rate risk limits. The table below reflects the change in market risk limits under the policy.


	June 30, 2017						December 31, 2016						March 31, 2018						December 31, 2017

Measurement of Market Risk Exposure

To measure our exposure, we discount the cash flows generated from modeling the terms and conditions of all interest rate-sensitive securities using current interest rates to determine their fair values or spreads to the swap curve for securities where third party prices are used. This includes considering explicit and embedded options using a lattice model or Monte Carlo simulation. We estimate yield curve, option, and basis risk exposures by calculating the fair value change in relation to various parallel changes in interest rates, implied volatility, prepayment speeds, spreads to the swap curve and mortgage rates.

The table below summarizes our sensitivity to various interest rate risk exposures in terms of changes in market value.

Option Risk Basis Risk
Yield Curve Risk Implied Volatility Prepayment Speeds Spread to Swap Curve Mortgage Spread
As of June 30, 2017 $ (1 ) $ (1 ) $ (3 ) (13 ) $ 1
As of December 31, 2016 (1 ) (1 ) (2 ) (14 ) 1



				Option Risk						Basis Risk
	Yield Curve Risk			Implied Volatility			Prepayment Speeds			Spread to Swap Curve		Mortgage Spread
As of March 31, 2018	$	(1	)	$	(2	)	$	(2	)	(12	)	$	1
As of December 31, 2017	(1		)	(2		)	(2		)	(13	)	1

Yield curve risk – Change in market value for a one basis point parallel increase in the swap curve.

Option risk (implied volatility) – Change in market value for a one percent parallel increase in the swaption volatility.

Option risk (prepayment speeds) – Change in market value for a one percent increase in prepayment speeds.

Basis risk (spread to swap curve) – Change in market value for a one basis point parallel increase in the spread to the swap curve.

Basis risk (mortgage spread) – Change in market value for a one basis point increase in mortgage rates.

~~Table of Contents~~

~~(Dollars in tables in millions except per share amounts unless otherwise indicated)~~

As of ~~June 30,~~March 31, 2018, our sensitivity to changes in implied volatility was $(2) million. At December 31, 2017, our sensitivity to changes in implied volatility was ~~$(1) million. At December 31, 2016, our sensitivity to changes in implied volatility was $(1)~~$(2) million. These sensitivities are limited in that they do not incorporate other risks, including but not limited to, non-parallel changes in yield curves, prepayment speeds, and basis risk related to differences between the swap and the other curves. Option positions embedded in our mortgage assets and callable debt impact our yield curve risk profile, such that swap curve changes significantly greater than one basis point cannot be linearly interpolated from the table above.

Duration of equity is another measure to express interest rate sensitivity. We report the results of our duration of equity calculations to the FHFA each quarter. We measure duration of equity in a base case using the actual yield curve as of a specified date and then shock it with an instantaneous shift of the entire curve. The following table presents the duration of equity reported by us to the FHFA in accordance with the FHFA's guidance, which prescribes that down and up interest-rate shocks equal 200 basis points. The results are shown in years of duration equity.


	June 30, 2017			December 31, 2016			Duration of equity
Scenario as of	Down 200 bps	Base	Up 200 bps	Down 200 bps	Base	Up 200 bps	Down 200 bps	Base	Up 200 bps
Duration of equity	2.4	1.0	1.7	2.3	1.3	1.8
March 31, 2018							2.1	1.2	1.8
December 31, 2017							2.9	1.2	2.2

As of ~~June 30, 2017,~~March 31, 2018, on a U.S. GAAP basis, our fair value surplus (relative to book value) was ~~$379~~$358 million, and our market value of equity to book value of equity ratio was ~~108%~~107%, compared to ~~$388~~$371 million and ~~108%~~107% at December 31, ~~2016.~~2017. Our market to book value of total capital for regulatory risk-based capital purposes differs from this GAAP calculation, as discussed in Note 11 - Capital and Mandatorily Redeemable Capital Stock (MRCS) to the financial statements.
