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. All our members are required to purchase our capital stock as a condition of membership. Our capital stock is not publicly traded, and is issued, repurchased or redeemed at par value, $100 per share, subject to certain statutory and regulatory limits. As a cooperative, we do business with our members, and former members (under limited circumstances). Specifically, we provide credit principally in the form of secured loans called advances. We also provide liquidity for home mortgage loans to members approved as Participating Financial Institutions (PFIs) through the Mortgage Partnership Finance^®(MPF^®) Program.

Our accounting and financial reporting policies conform to generally accepted accounting principles in the United States of America (GAAP). Amounts in prior periods may be reclassified to conform to the current presentation and, if material, are disclosed in the following notes.

In the opinion of management, all normal recurring adjustments have been included for a fair statement of this interim financial information. These unaudited financial statements and the following footnotes should be read in conjunction with the audited financial statements and footnotes for the year ended December 31, 2017, included in our Annual Report on Form 10-K (2017 Form 10-K) starting on page F-1, as filed with the Securities and Exchange Commission (SEC).

Unless otherwise specified, references to we, us, our, and the Bank are to the Federal Home Loan Bank of Chicago.

“Mortgage Partnership Finance”, “MPF”, “MPF Xtra”, and "Community First" are registered trademarks of the Federal Home Loan Bank of Chicago.

See the Glossary of Terms starting on page 58 for the definitions of certain terms used herein.

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.

Basis of Presentation

The basis of presentation pertaining to the consolidation of our variable interest entities has not changed since we filed our 2017 Form 10-K. The basis of presentation pertaining to our gross versus net presentation of financial instruments also has not changed since we filed our 2017 Form 10-K.

Refer to Note 1- Background and Basis of Presentation to the financial statements in our 2017 Form 10-K with respect to our basis of presentation for consolidation of variable interest entities and our gross versus net presentation of financial instruments for further details.

Note 2 – Summary of Significant Accounting Policies

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

Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01)

We are required to recognize 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 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 an effect on our financial condition, results of operations, and cash flows at the time of adoption.

Revenue from Contracts with Customers (ASU 2014-09)

The 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

Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12)

In August of 2017, the FASB issued targeted improvements to existing derivatives and hedging guidance to facilitate financial reporting that more closely reflects an entity’s risk management activities. We plan to adopt this guidance as of January 1, 2019. We are in the process of determining the expected effect of this 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.

Cash Flow Hedges:

•

For a cash flow hedge of interest rate risk of a variable-rate financial instrument, we would be able to designate the variability in cash flows 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 flows as the hedged risk in a cash flow hedge of a variable-rate instrument indexed to a non-benchmark interest rate.


•	The 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 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 for existing hedge relationships and for new 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 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 AOCI, will be recognized to the opening balance of 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 offsetting entry recognized as a cumulative effect adjustment.

•	Permits us to reclassify a debt security from held-to-maturity to available-for-sale if the debt security is eligible to be included in the hedged item involving the last-of-the layer method. Any unrealized gain or loss at the date of the transfer would be recorded in AOCI.


•	The presentation and disclosure guidance will be adopted on a prospective basis.

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. Specifically, the 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 (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 new guidance takes effect January 1, 2020. Upon adoption, any difference in the credit loss amount attributable to both our on balance sheet and off balance sheet financial instruments resulting from applying the expected credit loss methodology compared to our existing incurred loss methodology will be recognized as a cumulative-effect adjustment to our January 1, 2020 opening retained earnings balance. A prospective transition approach is required for debt securities. Accordingly, any OTTI write-downs on securities recognized prior to January 1, 2020 may not be reversed at the time of our adoption. Improvements in expected cash flows for these securities will continue to be accounted for as yield adjustments over their remaining life. 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 lease 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. Our existing practice is to recognize operating leases off-balance sheet. The expense related to our lease payments and the interest expense on our lease obligations will continue to be 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.

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 2017 Form 10-K.

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

The following table presents the changes in the cumulative amount of previously recorded OTTI credit losses on investment securities recognized into earnings for the reporting periods indicated.

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.



As of March 31, 2018	Amount		Weighted Average Contractual Interest Rate
Due in one year or less	$	22,954	1.74	%
One to two years	2,435		1.84	%
Two to three years	2,204		2.01	%
Three to four years	1,898		1.79	%
Four to five years	4,326		2.08	%
More than five years	17,049		1.83	%	^a
Par value	$	50,866	1.82	%


^a	The weighted average interest rate is relatively low when compared to other categories due to a majority of advances in this category consisting of variable rate advances which reset periodically at market prevailing interest rates.

We have no allowance for credit losses on our advances. See Note 8 - Allowance for Credit Losses to the financial statements for further information related to our credit risk on advances.

The following table reconciles the par value of our advances to the carrying amount on our statements of condition as of the dates indicated.

Note 8 – Allowance for Credit Losses

See Note 2 - Summary of Significant Accounting Policies to the financial statements in our 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-16 in our 2017 Form 10-K. There has been no material activity in our allowance for credit losses since December 31, 2017. The following table presents the recorded investment and the allowance for credit losses in conventional MPF Loans by impairment methodology.



As of	March 31, 2018		December 31, 2017
Recorded investment -
Individually evaluated for impairment	$	47	$	49
Collectively evaluated for impairment	4,357		4,167
Recorded investment	$	4,404	$	4,216

Allowance for credit losses -
Collectively evaluated for impairment	$	2	$	2

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. We do not recognize interest income on impaired conventional MPF Loans.

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 March 31, 2018, and December 31, 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

Refer to Note 2 - Summary of Significant Accounting Policies in our 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 Derivatives Clearing Organizations (DCOs) through 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 16 - Fair Value in our 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 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 Commodity 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 had been lowered from its current rating to the next lower rating by a major credit rating agency, such as Standard and Poor's or Moody’s, the amount of collateral we would have been required to 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 $64 million of investment securities that can be sold or repledged, as part of our initial margin related to cleared derivative transactions at 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 March 31, 2018.

Fair Value Hedges

The following table presents our fair value hedging results by the type of hedged item. We had no gain (loss) for hedges that no longer qualified as a fair value hedge. Additionally, the table indicates where fair value hedging results are classified in our statements of income. In this regard, the Amount Recorded in Net Interest Income column includes the following:


•	The amortization of closed fair value hedging adjustments, which are included in the interest income/expense line item of the respective hedged item type.


•	The effect of net interest settlements attributable to open derivative hedging instruments, which are recorded directly to the interest income/expense line item of the respective hedged item type.

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 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 not material as of March 31, 2018.

The following table presents our cash flow hedging results by type of hedged item. Additionally, the table indicates where cash flow hedging results are classified in our statements of income. In this regard, the Amount Recorded in Net Interest Income column includes the following:


•	The amortization of closed cash flow hedging adjustments, which are reclassified from AOCI into the interest income/expense line item of the respective hedged item type.


•	The effect of net interest settlements attributable to open derivative hedging instruments, which are recorded directly to the interest income/expense line item of the respective hedged item type.

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-44 of our 2017 Form 10-K. We complied with our minimum regulatory capital requirements as shown below.



	March 31, 2018						December 31, 2017
	Requirement			Actual			Requirement			Actual
Risk-based capital	$	1,131		$	5,248		$	1,075		$	5,051
Total regulatory capital	$	3,656		$	5,248		$	3,374		$	5,051
Total regulatory capital ratio	4.00		%	5.74		%	4.00		%	5.99		%
Leverage capital	$	4,570		$	7,873		$	4,218		$	7,577
Leverage capital ratio	5.00		%	8.61		%	5.00		%	8.98		%

Total regulatory capital and leverage capital includes mandatorily redeemable capital stock (MRCS) but does not include AOCI. Under the FHFA regulation on capital classifications and critical capital levels for the FHLBs, we are adequately capitalized.

The following members had regulatory capital stock exceeding 10% of our total regulatory capital stock outstanding (which includes MRCS):



As of March 31, 2018	Regulatory Capital Stock Outstanding			% of Total Outstanding		Amount of Which is Classified as a Liability (MRCS)
BMO Harris Bank, NA	$	269		14.2	%	$	—
One Mortgage Partners Corp.	245		^a	13.0	%	245
The Northern Trust Company	215			11.4	%	—


^a	One Mortgage Partners Corp. is a subsidiary of JPMorgan Chase Bank NA.

Repurchase of Excess Capital Stock

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.

Note 13 - Fair Value

The following table is a summary of the fair value estimates and related levels in the hierarchy. The carrying amounts are per the statements of condition. 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 or profitability of assets and liabilities. We had no transfers between levels for the periods shown. See Note 2 - Summary of Significant Accounting Policies in our 2017 Form 10-K for our fair value policies and Note 16 - Fair Value in our 2017 Form 10-K for our valuation techniques and significant inputs.

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 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 April 24, 2018, the 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 first quarter of 2018, the Board of Directors declared a dividend of 4.00% (annualized) for Class B1 activity capital stock (an increase of 50 basis points from the previous quarter) and a dividend of 1.60% (annualized) for Class B2 membership capital stock (an increase of 10 basis points from the previous quarter).

The Bank pays a higher dividend per share on Class B1 activity stock than on Class B2 membership stock to reward members who use the Bank’s advances and, thereby, support the financial health of the entire cooperative. The higher dividend members receive on Class B1 activity stock has the effect of lowering their cost of borrowing from the Bank.

Strong Member Activity Continues

During 2017, we reported strong growth in member activity and that activity continued in the first quarter of 2018. Advances outstanding with members were $50.8 billion and letters of credit were $20.1 billion at quarter-end. MPF Program activity continued to grow with $5.4 billion in MPF Loans outstanding on balance sheet at quarter-end.

Community Investment Programs in Full Swing

The first quarter of 2018 was a busy time for our Community Investment programs. The application period for Community First® Capacity-Building Grants was announced on March 6, Community First Disaster Relief Program funding for flood-hit communities in Wisconsin became available on March 12, the 2018 Downpayment Plus® (DPP®) Programs opened on March 12, and trainings for the 2018 competitive Affordable Housing Program have begun in anticipation of the round opening on May 7.

FHFA Issues Proposed Rule Amending the Affordable Housing Program Regulations

FHFA recently published proposed amendments to the AHP regulations. The amendments offer some benefits to the AHP program, but also pose some challenges that could impact the development and implementation of AHP funding. See Legislative and Regulatory Developments starting on page 52 for more details on the proposed amendments.

News from Our District

In April, Wisconsin Governor Scott Walker signed into law the 2017 Wisconsin Act 340, an omnibus banking act containing three provisions impacting the Bank. See Legislative and Regulatory Developments starting on page 52 for more details on this act.

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;


•	OTTI 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. Amortized cost basis is used to compute the average balances for most of our financial instruments, including MPF Loans held in portfolio that are on nonaccrual 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 the net interest income components, as discussed above, applicable to our interest earning assets and interest bearing liabilities.


•	Yield/Rate: Effective yields/rates are based on total interest and average balances as defined above. Yields/rates are calculated on an annualized basis.


•	Any changes due to the combined volume/rate variance have been allocated to volume.

The following is an analysis of the preceding table and unless otherwise indicated, comparisons apply to the three month periods ending March 31, 2018 compared to March 31, 2017.

•

Interest income from investment securities declined as MBS/ABS matured or paid down and we did not make new investments in MBS/ABS under FHFA regulatory limits as discussed in Investments on page 10 in our 2017 Form 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, which resulted primarily from rate hikes by the Federal Reserve 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 was essentially unchanged from 2017.


•	Interest income from Federal Funds sold and securities purchased under agreements to resell increased both due to 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 advances and 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 rates, and to a lesser extent, an increase in notes and bonds outstanding.

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.

The following is an analysis of the preceding table and unless otherwise indicated, comparisons apply to the three month periods ending March 31, 2018 and March 31, 2017.

We had 461 employees as of March 31, 2018, compared to 452 as of March 31, 2017. Compensation and benefit expenses declined slightly due to a decline in anticipated pension expense recorded during the first quarter. However, we can not predict future return trends at this time and this reduction may not be sustained.

Other consists primarily of our share of the funding for the FHFA, our regulator, and the Office of Finance, which manages the consolidated obligation debt issuances of the FHLBs. In addition, Other includes MPF related non-operating expenses/gains on the sale of real estate owned.

Assessments

We record the Affordable Housing Program (AHP) assessment expense at a rate of 10% of income before assessments, excluding interest expense on MRCS. See Note 11 - Affordable Housing Program in our 2017 Form 10-K for further details.

The following is an analysis of the above table and unless otherwise indicated, comparisons apply to the three month periods ending March 31, 2018 and March 31, 2017.

Net unrealized gain (loss) on available-for-sale securities

The net unrealized loss on our available for sale (AFS) portfolio for 2018 is attributable to the reversal of net unrealized gains from prior reporting periods. The net unrealized gains on our AFS securities reverse as these securities approach maturity. This is because we expect to receive par value at the maturity of these AFS securities. As of March 31, 2018, we had a net unrealized gain balance remaining in AOCI attributable to our AFS portfolio.

Noncredit OTTI on held-to-maturity securities

We recorded unrealized noncredit impairments on held-to-maturity securities during the last financial crisis. As the market has recovered and because we intend to hold these securities to maturity, we are recording accretion to the carrying amount of the

securities, reversing the remaining loss balance in AOCI. The annual accretion gains declined in 2018 and are expected to continue to decline as the securities near maturity.

Net unrealized gain (loss) on cash flow hedges

The net unrealized gain on cash flow hedges during the periods presented resulted from an increase in shorter term interest rates as a result of actions by the Federal Reserve Bank.

We did not recognize any instrument-specific credit risk in our statements of comprehensive income as of March 31, 2018 due to our credit standing.

The following is an analysis of the above table and comparisons apply to March 31, 2018 compared to December 31, 2017.

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

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 securities that matured or paid down and were not replaced, as noted in Results of Operations on page 40.

Advances

Advances increased to the highest outstanding quarter end balance in our history due to 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 may decrease.

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

We had a small net increase in our outstanding MPF Loans from prior year end, as our purchases of new loans 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 March 31, 2018, we 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 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 $3.2 billion of total assets. As of March 31, 2018, our overnight liquidity was $24.0 billion or 26% of total assets, giving us an excess overnight liquidity of $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 March 31, 2018, we had excess liquidity of $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 $16.9 billion as of 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 five 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 18 in the Risk Factors section of our 2017 Form 10-K. In July the FHFA proposed to rescind certain minimum regulatory liquidity requirements for the FHLBs as further discussed in Legislative and Regulatory Developments on page 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 flows of our assets, including prepayments made in advance of maturity.



	MPF Loans Held in Portfolio		Investment Securities
As of March 31, 2018	MPF Loans Held in Portfolio		Available-for Sale		Held-to-Maturity
Year of Expected Principal Cash Flows
One year or less	$	694	$	2,553	$	1,316
After one year through five years	2,051		7,475		1,943
After five years through ten years	1,351		1,371		435
After ten years	1,189		531		118
Total	$	5,285	$	11,930	$	3,812

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 22 of the Risk Factors section in our 2017 Form 10-K.

Funding

Conditions in Financial Markets

In March 2018, the Federal Open Market Committee (FOMC) raised the target range for the federal fund rate by 25 basis points to a range of 1.50 percent to 1.75 percent. This is the sixth rate hike since the FOMC began to raise rates in December 2015. The markets anticipate another 25 basis point increase in the target range for the federal fund rate in the second quarter of 2018.

We maintained ready access to funding during the first quarter of 2018.

Cash flows from operating activities



Three months ended March 31,	2018		2017
Net cash provided by (used in) operating activities	$	135	$	159

The decline in net cash provided by operating activities resulted primarily from a noncash adjustment related to derivatives and hedging activities.

Cash flows from investing activities with significant changes



Three months ended March 31,	2018			2017
Liquid assets (Federal Funds sold, securities purchased under agreements to resell, and interest bearing deposits)	$	(3,050	)	$	(2,492	)
Investment securities	(1,170		)	2,028
Advances	(2,847		)	2,726
Other	(165		)	32
Net cash provided by (used in) investing activities	$	(7,232	)	$	2,294

Our investing activities consist predominantly of liquid assets, securities held for investment, and advances. The decline in net cash provided by (used in) investing activities primarily resulted from the following:


•	The increase in liquid assets reflect our increased liquidity needs to meet the demands of our members.


•	Securities held for investment reflect the purchases made in our trading security portfolio in 2018. The rest of our investment security portfolio continued to paydown in 2018.


•	Advances reflect the increase in advances outstanding during 2018, as compared to the reduction in advances outstanding in 2017.

Cash flows from financing activities with significant changes



Three months ended March 31,	2018		2017
Consolidated obligation discount notes	$	292	$	(3,142	)
Consolidated obligation bonds	6,524		750
Capital stock	136		(426		)
Other	143		48
Net cash provided by (used in) financing activities	$	7,095	$	(2,770	)

Our financing activities primarily reflect cash flows related to issuing and repaying consolidated obligations. The proceeds from the net increases in our discount notes and bonds were primarily utilized to fund the net increases in our investing as noted above. The increase in net cash provided by (used in) financing activities primarily resulted from the following:


•	An increase in 2018 in the amount of our consolidated obligations used to fund the growth in our balance sheet, compared to 2017, when there was a net decrease in our consolidated obligations outstanding. In first quarter of 2018, we relied primarily on consolidated obligation bonds for our funding.


•	An increase in capital stock outstanding as members purchased capital stock to support their advance borrowings.

Capital Resources

Capital Rules

Under 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 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.

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 the Reduced Capitalization Advance Program (RCAP) as further discussed below. Each member’s activity stock requirement 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, 2017, and is thus the operative cap during the remainder of 2018 unless the Board sets a new cap.

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.

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.

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 of March 31, 2018, and December 31, 2017, RCAP advances outstanding total $24.7 billion to 157 members and $24.7 billion to 158 members, respectively.

Repurchase of Excess Capital Stock

Beginning in 2017, we began repurchasing all excess Class B2 membership stock on a weekly basis at par value, i.e., $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.

For details on the financial and capital thresholds relating to repurchases, see Repurchase of Excess Capital Stock on page 57 of our 2017 Form 10-K.

Capital Amounts

The following table reconciles our capital reported in our statements of condition to the amount of capital stock reported for regulatory purposes. MRCS is included in the calculation of the regulatory capital and leverage ratios but is recorded in other liabilities in our statements of condition.



	March 31, 2018		December 31, 2017		Change
Capital Stock	$	1,579	$	1,443	$	136
MRCS	311		311		—
Regulatory capital stock	1,890		1,754		136
Retained earnings	3,358		3,297		61
Regulatory capital	$	5,248	$	5,051	$	197

Capital stock	$	1,579	$	1,443	$	136
Retained earnings	3,358		3,297		61
Accumulated other comprehensive income (loss)	126		112		14
GAAP capital	$	5,063	$	4,852	$	211

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 2018, credit deterioration may negatively impact our remaining 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 the Risk Factors section on page 16 of our 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 April 24, 2018, our Board of Directors declared a 4.00% dividend (annualized) for Class B1 activity stock and a 1.60% dividend (annualized) for Class B2 membership stock based on our preliminary financial results for the first quarter of 2018. This dividend, including dividends on mandatorily redeemable capital stock, totaled $16 million and is scheduled for payment on May 15, 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 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 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-45 in our 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 61 in our 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, $50.9 billion were advances (par value) and $20.1 billion were letters of credit at March 31, 2018, compared to $48.0 billion and $19.6 billion at December 31, 2017.



	March 31, 2018					December 31, 2017
Rating	Borrowing Members	Credit Outstanding		Collateral Loan Value		Borrowing Members	Credit Outstanding		Collateral Loan Value
1-3	485	$	70,532	$	120,774	495	$	67,105	$	116,810

Total	502	$	71,126	$	121,568	513	$	67,723	$	117,621

The majority of members assigned a 4 rating in the above table were required to submit specific collateral listings and the majority of members assigned a 5 rating were required to deliver collateral to us or a third party custodian on our behalf.

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 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 on page 63 of our 2017 Form 10-K.

Mortgage Repurchase Risk

For details on our mortgage repurchase risk in connection with our sale of MPF Loans to third party investors and MPF Loans securitized into MBS when a loan eligibility requirement or other warranty is breached, see Mortgage Repurchase Risk on page 65 in our 2017 Form 10-K.

Investment Securities

We hold a variety of AA or better rated investment securities, mostly government backed or insured securities such as GSE debt and FFELP ABS, and we believe these investments are low risk. There were no material changes in the credit ratings of these securities since December 31, 2017. For further details see Investment Securities by Rating on page 67 in our 2017 Form 10-K. Except for private label MBS, we have never taken an impairment charge on our investment securities.

Our private label MBS are predominantly variable rate securities rated below investment grade (BBB). There were no material changes in overall credit quality since December 31, 2017, nor have we acquired any new private label MBS. We last had an other-than-temporary impairment (OTTI) loss on private label MBS in 2012. We currently have unrealized gains on these securities as their market values have improved from the impaired values and subsequent to 2012 we have begun recording accretion gains on these securities back into income. For further details see Note 5 - Investment Securities to the financial statements.

Unsecured Short-Term Investments

See Unsecured Short-Term Investments page 70 in our 2017 Form 10-K for further details on our unsecured short-term investments as well as policies and procedures to limit and monitor our unsecured credit risk exposure.

The following table presents the credit ratings of our unsecured investment credit exposures by the domicile of the counterparty or the domicile of the counterparty's parent for U.S. branches and agency offices of foreign commercial banks.

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 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 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 March 14, 2018, the FHFA published a proposed rule to amend the operating requirements of the 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 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 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 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 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 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 to the 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 Comptroller of the Currency ("OCC"), Federal Reserve Board ("FRB"), Federal Deposit Insurance Corporation ("FDIC"), Farm Credit Administration and FHFA Proposed Rule on 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 “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 QFC rules previously published by the OCC, FRB, and 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 the proposed rule were due by April 23, 2018. We continue to evaluate the proposed rule, but do not expect this rule, if adopted substantially as proposed, to materially affect our financial condition or results of operations.

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.



	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 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.

As of 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 $(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.
