Notes to Financial Statements

(Unaudited, $ amounts in thousands unless otherwise indicated)

Note 1 - Summary of Significant Accounting Policies

We use acronyms and terms throughout these notes to financial statements that are defined herein or in the Glossary of Terms. Unless the context otherwise requires, the terms "Bank," "we," "us," and "our" refer to the Federal Home Loan Bank of Indianapolis or its management.

Basis of Presentation. The accompanying interim financial statements have been prepared in accordance with GAAP and SEC requirements for interim financial information. Accordingly, they do not include all of the information and disclosures required by GAAP for complete financial statements. Certain disclosures that would have substantially duplicated the disclosures in the financial statements, and notes thereto, included in our 2017 Form 10-K have been omitted unless the information contained in those disclosures materially changed. Therefore, these interim financial statements should be read in conjunction with our audited financial statements, and notes thereto, included in our 2017 Form 10-K.

The financial statements contain all adjustments that are, in the opinion of management, necessary for a fair statement of our financial position, results of operations and cash flows for the interim periods presented. All such adjustments were of a normal recurring nature. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full calendar year or any other interim period.

Our significant accounting policies and certain other disclosures are set forthin our 2017 Form 10-K in Note 1 - Summary of Significant Accounting Policies. There have been no significant changes to these policies through September 30, 2018. However, see Note 2 - Recently Adopted and Issued Accounting Guidance.

Use of Estimates.When preparing financial statements in accordance with GAAP, we are required to make subjective assumptions and estimates that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expense. The most significant estimates pertain to derivatives and hedging activities, fair value, the provision for credit losses, and OTTI. Although the reported amounts and disclosures reflect our best estimates, actual results could differ significantly from these estimates.

Reclassifications. We have reclassified certain amounts from the prior period to conform to the current period presentation. These reclassifications had no effect on total assets, total liabilities, total capital, net income, total comprehensive income, or net cash flows.

Note 2 - Recently Adopted and Issued Accounting Guidance

Recently Adopted Accounting Guidance.

Revenue from Contracts with Customers (ASU 2014-09). On May 28, 2014, the FASB issued guidance on revenue from contracts with customers. This guidance outlines a comprehensive model for recognizing revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry specific guidance. In addition, this guidance amends the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are not in a contract with a customer. This guidance applies to all contracts with customers except those that are within the scope of certain other standards, such as financial instruments, certain guarantees, insurance contracts, or lease contracts.

The guidance, which included subsequent amendments, was effective for our interim and annual periods beginning on January 1, 2018. The adoption of this guidance had no effect on our financial condition, results of operations, or cash flows.

Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01). On January 5, 2016, the FASB issued amended guidance on certain aspects of recognition, measurement, presentation, and disclosure of financial instruments.

The guidance was effective for our interim and annual periods beginning on January 1, 2018. The adoption of this guidance had no effect on our financial condition, results of operations, or cash flows.

(Unaudited, $ amounts in thousands unless otherwise indicated)

Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15). On August 26, 2016, the FASB issued amendments intended to reduce diversity in practice in how cash receipts and cash payments are presented and classified on the statement of cash flows for certain transactions.

These amendments were adopted on a retrospective basis effective beginning on January 1, 2018. As a result, the amount of interest payments as reported in the supplemental disclosures increased for the nine months ended September 30, 2017 by $101,253. The adoption of these amendments had no effect on our financial condition, results of operations or cash flows.

Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (ASU 2017-07). On March 10, 2017, the FASB issued amendments to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The amendments require that an employer disaggregate the service cost component from the other components of net pension and benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement.

These amendments were effective for our interim and annual periods beginning on January 1, 2018. The adoption of these amendments had no effect on our financial condition, results of operations, or cash flows. However, the amendments were applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost on the income statement, which resulted in a reclassification from compensation and benefits to other expenses for the non-service components for the three and nine months ended September 30, 2017 of $526 and $1,500, respectively.

Recently Issued Accounting Guidance.

Leases (ASU 2016-02). On February 25, 2016, the FASB issued guidance which requires recognition of lease assets and lease liabilities on the statement of condition and disclosure of key information about leasing arrangements. In particular, this guidance requires a lessee, in an operating or finance lease, to recognize on the statement of condition a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. However, for a lease with a term of 12 months or less, a lessee is permitted to make an accounting policy election not to recognize a lease asset and lease liability. Under previous guidance, a lessee was not required to recognize a lease asset and lease liability arising from an operating lease on the statement of condition. While this guidance does not fundamentally change lessor accounting, some changes have been made to align that guidance with the lessee guidance and other areas within GAAP.

This guidance is effective for the interim and annual periods beginning on January 1, 2019. As amended, the guidance allows lessors and lessees to recognize and measure leases at the adoption date by recognizing a cumulative-effect adjustment directly to retained earnings. Upon adoption, we will report higher assets and liabilities as a result of including right-of-use assets and lease liabilities on the statement of condition, but its effect on our financial condition, results of operations, and cash flows would not currently be material.

Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12). On August 28, 2017, the FASB issued amended guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. This guidance requires that, for fair value hedges, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness be presented in the same income statement line that is used to present the earnings effect of the hedged item. For cash flow hedges, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness must be recorded in OCI. In addition, the amendments include certain targeted improvements to the assessment of hedge effectiveness and permit, among other things, the following:

• Measurement of the change in fair value of the hedged item on the basis of the benchmark rate component of the contractual coupon cash flows determined at hedge inception.

• Measurement of the hedged item in a partial-term fair value hedge of interest-rate risk by assuming the hedged item has a term that reflects only the designated cash flows being hedged.

• Consideration only of how changes in the benchmark interest rate affect a decision to settle a prepayable instrument before its scheduled maturity in calculating the change in the fair value of the hedged item attributable to interest-rate risk.

Notes to Financial Statements, continued

(Unaudited, $ amounts in thousands unless otherwise indicated)

This guidance is effective for the interim and annual periods beginning on January 1, 2019. Its adoption would currently have no effect on our financial condition, results of operations, or cash flows. However, the amended presentation and disclosure guidance will result in a prospective reclassification on the income statement of the change in fair value of hedging instruments and related hedged items in fair value hedging relationships from other income to interest income.

Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). On August 28, 2018, the FASB issued guidance to update the disclosure requirements for fair value measurement. These amendments were issued as part of the FASB's disclosure framework project and are intended to improve disclosure effectiveness.

The guidance is effective for the interim and annual periods beginning on January 1, 2020, and early adoption is permitted; however, we currently plan to adopt this guidance on the effective date. The adoption may have an effect on our disclosures, but will not have any effect on our financial condition, results of operations, or cash flows.

Changes to the Disclosure Requirements for Defined Benefit Plans (ASU 2018-14). On August 28, 2018, the FASB issued guidance to modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. These amendments were issued as part of the FASB's disclosure framework project and are intended to improve disclosure effectiveness.

The guidance is effective for the annual period ended December 31, 2020, and early adoption is permitted; however, we currently plan to adopt this guidance on the effective date. The adoption may have an effect on our disclosures, but will not have any effect on our financial condition, results of operations, or cash flows.

Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (ASU 2018-15). On August 29, 2018, the FASB issued guidance on implementation costs incurred in a hosting arrangement as a service contract. The amendments align the requirements for capitalizing such costs with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software and hosting arrangements that include an internal-use software license.

This guidance is effective for the interim and annual periods beginning on January 1, 2020, and early adoption is permitted; however, we currently plan to adopt this guidance on the effective date. We are in the process of evaluating this guidance, but we currently do not expect its effect on our financial condition, results of operations, or cash flows to be material.

Inclusion of the Secured Overnight Financing Rate (SOFR) OIS Rate as a Benchmark Interest Rate for Hedge Accounting Purposes (ASU 2018-16). On October 25, 2018, to facilitate the LIBOR to SOFR transition, the FASB issued guidance permitting the OIS rate based on SOFR as an eligible U.S. benchmark interest rate for hedge accounting purposes.

This guidance is effective for the interim and annual periods beginning on January 1, 2019, concurrent with the adoption of ASU 2017-12. We are in the process of evaluating the impact that this guidance may have on our hedging strategies, but we currently do not expect its effect on our financial condition, results of operations, or cash flows to be material.

Contractual Maturity.The amortized cost and estimated fair value of non-MBS AFS securities are presented below by contractual maturity. MBS are not presented by contractual maturity because their actual maturities will likely differ from their contractual maturities as borrowers have the right to prepay their obligations with or without prepayment fees.

Realized Gains and Losses. During the nine months ended September 30, 2018, for strategic, economic and operational reasons, we sold all of our AFS and HTM investments in private-label RMBS and ABS. Of the OTTI AFS securities sold in 2018, none were in an unrealized loss position. Proceeds from the AFS sales totaled $203,841, resulting in realized gains of $32,407 determined by the specific identification method. There were no sales during the three or nine months ended September 30, 2017.

As of September 30, 2018, we had no intention of selling any AFS securities in an unrealized loss position nor did we consider it more likely than not that we will be required to sell these securities before our anticipated recovery of each security's remaining amortized cost basis.

⁽¹⁾  For private-label ABS, at December 31, 2017, the total of unrealized losses does not agree to total gross unrecognized holding losses of $405. Total unrealized losses include non-credit-related OTTI losses recorded in AOCI of $51 and gross unrecognized holding gains on previously OTTI securities of $40.

Realized Gains and Losses. During the nine months ended September 30, 2018, for strategic, economic and operational reasons, we sold all of our AFS and HTM investments in private-label RMBS and ABS. The amortized cost of the HTM securities sold totaled $41,271. Proceeds from the HTM sales totaled $41,226, resulting in realized losses of $45 determined by the specific identification method. For each of these HTM securities, we had previously collected at least 85% of the principal outstanding at the time of acquisition due to prepayments or scheduled payments over the term. As such, the sales were considered maturities for purposes of security classification. There were no sales of HTM securities during the three or nine months ended September 30, 2017.

As of September 30, 2018, we had no intention of selling any HTM securities in an unrealized loss position nor did we consider it more likely than not that we will be required to sell these securities before our anticipated recovery of each security's remaining amortized cost basis.

OTTI Evaluation Process and Results - Private-label RMBS and ABS.

Results of OTTI Evaluation Process - Private-label RMBS and ABS. As part of our evaluation for the three months ended March 31, 2018, we did not have any change in intent to sell, nor were we required to sell, any OTTI security. Therefore, we performed a cash flow analysis at that time to determine whether we expected to recover the entire amortized cost of each security. As a result of that cash flow analysis, no OTTI credit losses were recognized. At that time, we determined that the unrealized losses on the remaining private-label RMBS and ABS were temporary as we expected to recover the entire amortized cost.

During the nine months ended September 30, 2018, for strategic, economic and operational reasons, we sold all of our investments in private-label RMBS and ABS. The following table presents a rollforward of the amounts related to credit losses recognized in earnings.

Other U.S. and GSE Obligations and TVA Debentures. For other U.S. obligations, GSE obligations, and TVA debentures, we determined that, based on current expectations, the strength of the issuers' guarantees through direct obligations of or support from the United States government is sufficient to protect us from any losses. As a result, all of the gross unrealized losses as of September 30, 2018 are considered temporary.

⁽¹⁾  The recorded investment in a loan is the UPB of the loan, adjusted for accrued interest, net of any deferred loan fees or costs, unamortized premiums or discounts (which may include the basis adjustment related to any gain or loss on a delivery commitment prior to being funded) and direct charge-offs. The recorded investment is not net of any valuation allowance.

⁽²⁾  Includes loans for which the decision of foreclosure or similar alternative, such as pursuit of deed-in-lieu of foreclosure, has been reported. Loans in process of foreclosure are included in past due categories depending on their delinquency status, but are not necessarily considered to be on non-accrual status.

⁽³⁾  Represents loans 90 days or more past due (including loans in process of foreclosure) expressed as a percentage of the total recorded investment in mortgage loans. The percentage excludes principal and interest amounts previously paid in full by the servicers on conventional loans that are pending resolution of potential loss claims. Our servicers repurchase seriously delinquent government loans, including FHA loans, when certain criteria are met.

⁽⁴⁾  Although our past due scheduled/scheduled MPP loans are classified as loans past due 90 days or more based on the loan's delinquency status, we do not consider these loans to be on non-accrual status.

Note 9 - Derivatives and Hedging Activities

Managing Credit Risk on Derivatives. We are subject to credit risk due to the risk of nonperformance by the counterparties to our derivative transactions.

Uncleared Derivatives. For certain of our uncleared derivatives, we have credit support agreements that contain provisions requiring us to post additional collateral with our counterparties if there is deterioration in our credit rating. If our credit rating is lowered by an NRSRO, we could be required to deliver additional collateral on uncleared derivative instruments in net liability positions. The aggregate estimated fair value of all uncleared derivative instruments with credit-risk-related contingent features that were in a net liability position (before cash collateral and related accrued interest on cash collateral) at September 30, 2018 was $599, for which we were not required to post collateral. If our credit rating had been lowered by an NRSRO (from an S&P equivalent of AA+ to AA), we would not have been required to deliver additional collateral to our uncleared derivative counterparties at September 30, 2018.

Cleared Derivatives. The clearinghouse determines margin requirements, which are generally not based on credit ratings. However, clearing agents may require additional margin to be posted by us based on credit considerations, including but not limited to any credit rating downgrades. At September 30, 2018, we were not required by our clearing agents to post any additional margin.

Through September 30, 2018, certain members had requested redemptions of their Class B stock, but the related stock outstanding at September 30, 2018 and December 31, 2017 totaling $5,426 and $5,144, respectively, was not considered mandatorily redeemable and reclassified to MRCS because the requesting members may revoke their requests, without substantial penalty, throughout the five-year waiting period. Therefore, these requests are not considered sufficiently substantive in nature. However, we consider redemption requests related to mergers, acquisitions or charter terminations, as well as involuntary terminations from membership, to be sufficiently substantive when made and, therefore, the related stock is considered mandatorily redeemable and reclassified to MRCS.

Mandatorily Redeemable Capital Stock.The following table presents the activity in our MRCS.

In accordance with the Final Membership Rule, captive insurance companies that were admitted as FHLBank members on or after September 12, 2014 had their memberships terminated by February 19, 2017. All of their outstanding Class B stock, totaling $3,021 at December 31, 2016, was repurchased on or before February 19, 2017.

The following table presents MRCS by contractual year of redemption. The year of redemption is the later of (i) the final year of the five-year redemption period, or (ii) the first year in which a non-member no longer has an activity-based stock requirement.

Pledged Collateral.At September 30, 2018 and December 31, 2017, we had pledged cash collateral, at par, of $124,987 and $16,437, respectively, to counterparties and clearing agents. At September 30, 2018 and December 31, 2017, we had not pledged any securities as collateral.

Legal Proceedings. We are subject to legal proceedings arising in the normal course of business. We record an accrual for a loss contingency when it is probable that a loss for which we could be liable has been incurred and the amount can be reasonably estimated. After consultation with legal counsel, management does not anticipate that the ultimate liability, if any, arising out of these proceedings could have a material effect on our financial condition, results of operations or cash flows.

In 2010, we filed a complaint asserting claims against several entities for negligent misrepresentation and violations of state and federal securities law occurring in connection with the sale of private-label RMBS to us. In 2013, 2014 and 2015, we executed confidential settlement agreements with certain defendants in this litigation, pursuant to which we have dismissed all pending claims against, and provided legal releases to, certain entities with respect to all applicable securities at issue in the litigation, in consideration of our receipt of cash payments from or on behalf of those defendants. We had previously dismissed the complaint as to the other named defendants. As a result, all proceedings in the RMBS litigation we filed have been concluded. Cash settlement payments, net of legal fees and litigation expenses, totaled $317 for the three and nine months ended September 30, 2018, respectively, compared to $134 and $312 for the three and nine months ended September 30, 2017, respectively, and were recorded in other income.

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Presentation 

This discussion and analysis by management of the Bank's financial condition and results of operations should be read in conjunction with our 2017 Form 10-K and the Financial Statements and related Notes to Financial Statements contained in Item 1. Financial Statements.

Unless otherwise stated, amounts disclosed in this Item are rounded to the nearest million; therefore, dollar amounts of less than one million may not be reflected and, due to rounding, may not appear to agree to the amounts presented in thousands in the Financial Statements and related Notes to Financial Statements. Amounts used to calculate dollar and percentage changes are based on numbers in the thousands. Accordingly, calculations based upon the disclosed amounts (millions) may not produce the same results.

Executive Summary

Overview. We are a regional wholesale bank that serves as a financial intermediary between the capital markets and our members. We primarily make secured loans in the form of advances to our members and purchase whole mortgage loans from our members. Additionally, we purchase other investments and provide other financial services to our members. As an FHLBank, we are generally designed to expand and contract in asset size as the needs of our members and their communities change over time.

Our principal source of funding is the proceeds from the sale to the public of FHLBank debt instruments, called consolidated obligations, which are the joint and several obligation of all FHLBanks. We obtain additional funds from deposits, other borrowings, and the sale of capital stock to our members.

Our primary source of revenue is interest earned on advances, mortgage loans, and long- and short-term investments.

Our net interest income is primarily determined by the spread between the interest rate earned on our assets and the interest rate paid on our share of consolidated obligations. We use funding and hedging strategies to manage the related interest-rate risk.

Due to our cooperative structure and wholesale nature, we typically earn a narrow interest spread. Accordingly, our net income is relatively low compared to our total assets and capital.

We group our products and services within two operating segments: traditional and mortgage loans.

Economic Environment. The Bank’s financial performance is influenced by a number of regional and national economic and market factors, including the level and volatility of market interest rates, inflation or deflation, monetary policies, and the strength of housing markets.

The U.S. economy continued to grow through the third quarter of 2018. The current economic expansion has run 111 months through the third quarter, compared to the average post-war economic expansion length of 47 months. In the third quarter of 2018, real U.S. Gross Domestic Product posted an annualized increase of 3.5 percent. Strong business, government, and consumer spending boosted such growth. While quite solid, it is a small decline from the 4.2 percent annualized increase in the second quarter 2018.

38

Other indications of robust economic growth in the third quarter of 2018 included capital market returns, labor market conditions, and corporate activity. Through the end of the quarter, equity markets remained solid, though markets in the U.S. fared far better than other global markets. Bond market returns, on the other hand, primarily posted negative total returns in the U.S. since the beginning of the year, as a result of a rising interest-rate environment. However, certain floating rate bonds, high yield bonds, and convertible securities sectors posted large cash inflows and positive returns, more in line with equity markets, as investors searched for returns outside of traditional stock and bond markets. In addition to rising interest rates, global central banks, including the Federal Reserve, began in concert to shrink their balance sheet holdings of bonds. Central bank bond purchases as part of a quantitative easing operation helped boost demand and liquidity while reducing borrowing costs for bond issuers since the financial crisis. Global central bank holdings peaked in early 2017 and are expected to steadily decline over the next five years, in accordance with published plans of global central banks. Continued balance sheet shrinkage will, all else equal, put additional pressure on rising interest rates. If economic conditions significantly deteriorate during this timeframe, this unwinding of quantitative easing can certainly be adjusted accordingly.

Labor markets remained very strong, with unemployment rates near record lows. The long-time lack of wage growth accompanying low unemployment levels appears to be dissipating, as wage inflation begins to take root. Regardless of the causes, low unemployment and wage growth characteristically lead to higher consumer confidence and spending, helping to perpetuate economic growth. In September 2018, the national unemployment rate declined to 3.7 percent, down from 4.0 percent in June 2018 and 4.2 percent in September 2017. According to the Bureau of Labor Statistics, the total number of unemployed persons at the end of September 2018 was 6.0 million, while the total number of involuntary part-time employees (those who would prefer full-time employment but can only get part-time jobs) increased to 4.6 million.

Both Indiana and Michigan have continued to show improvement in labor markets over the past five years, in line with national trends. As of September 30, 2018, the unemployment rate in Michigan remained slightly above the national average at 4.0 percent, an improvement from 4.7 percent and 4.4 percent as of the end of the first and second quarters of 2018, respectively. The unemployment rate in Michigan has improved in each of the past five months. Indiana’s employment picture was mixed. Though the unemployment rate ticked up from 3.3 percent at the end of June 2018 to 3.5 percent at the end of September, the total number of jobs increased over the period. The Indiana labor force over the third quarter and over the prior 12 months increased at a rate greater than the rate of job growth. Despite the uptick, the unemployment rate remained below the national average.

Tempering the strong economic reports of prior months is the potential of a continued and expanded global trade war, tight labor markets and other supply costs and constraints, higher interest rates, and the repricing of assets and debt. The higher debt service costs associated with higher interest rates and higher risk premiums have the potential for significant credit events as lower-quality borrowers default or have difficulty obtaining new funding. Government and corporate borrowers, as well as the domestic economy, have been beneficiaries of low interest rates and aggressive monetary stimulus. The Federal Reserve has continued to indicate that the economy is strong enough for it to continue to unwind quantitative easing activity and to continue to increase the overnight federal funds rate. Though this is not universally popular, most market participants realize the necessity of unwinding the relatively loose monetary policy and still near-zero real interest rates, particularly when combined with the massive fiscal stimulus enacted with the personal and corporate tax cuts that went into effect this year. Since the beginning of the year, the Federal Reserve has raised the overnight federal funds rate by 75 basis points (0.75 percent) with the upper target rate now at 2.25 percent. Since the beginning of the tightening cycle in December of 2015, the Federal Reserve has raised the target rate eight times in 25 basis point increments. The ten-year Treasury rate has increased along with short-term rates, and has been at or near the 3% level. Though higher interest rates have the ability to take a toll on markets, businesses, and consumers, the yield curve has remained upward sloping instead of inverted. An inverted yield curve, or one where longer-term rates are below shorter-term rates, is often a leading indicator of a decline in economic growth.

39

The housing market remains positive, but has begun to lose momentum despite the strength in the overall economy. A shortage of existing home inventory, increased builder costs, and higher mortgage rates are beginning to impact the availability and affordability of the housing market. According to the Mortgage Bankers Association, mortgage originations continued to climb modestly in each of the first three quarters of 2018 after a slow start to the year, driven primarily by first-lien 1-4 family purchase mortgages. Total single family mortgage originations were $457 billion in the third quarter of 2018, resulting in production for the first nine months of 2018 to $1,251 billion, down from $1,309 billion for the same period in 2017. Mortgages for refinancing as a share of total originations dropped as mortgage rates have risen along with overall interest rates. New housing starts posted a seasonally adjusted annual rate of 1.21 million units in September 2018, down 5.3 percent from August 2018. After climbing in each of the first three months of 2018, the volume of existing home sales has declined in each of the past six months, ending in September 2018 at a level of 5.3 million units.

In July 2017, the United Kingdom's Financial Conduct Authority ("FCA"), which has regulated LIBOR since April 2013, announced it would exit from LIBOR after 2021. In response, the FRB convened the Alternative Reference Rates Committee ("ARRC") to identify a set of alternative reference interest rates for possible use as market benchmarks. The ARRC has identified the Secured Overnight Financing Rate ("SOFR") as an alternative rate and the Federal Reserve Bank of New York began publishing SOFR rates in the second quarter of 2018. SOFR is based on a broad segment of the overnight U.S. Treasury securities repurchase agreement market and is intended to be a measure of the cost of borrowing cash overnight, collateralized by Treasury securities. During the third quarter of 2018, certain market participants began moving towards the utilization of SOFR as a possible LIBOR replacement through the issuance of debt securities indexed to SOFR. On October 25, 2018, the FASB issued guidance permitting the OIS rate based on SOFR as an eligible U.S. benchmark interest rate for hedge accounting purposes.

Impact on Operating Results. Market interest rates and trends affect yields and margins on earning assets, including advances, purchased mortgage loans, and our investment portfolio, all of which contribute to our overall profitability. Additionally, market interest rates drive mortgage origination and prepayment activity, which can lead to both favorable and unfavorable net interest margin volatility in our MPP and MBS portfolios. A flat or inverted yield curve, in which the difference between short-term interest rates and long-term interest rates is low or negative, respectively, can have an unfavorable impact on our net interest margins.

Lending and investing activity by our member institutions is a key driver for our balance sheet and income growth. Such activity is a function of both prevailing interest rates and economic activity, including local economic factors, particularly relating to the housing and mortgage markets. Positive economic trends could drive interest rates higher, which could impair growth of the mortgage market. A less active mortgage market could affect demand for advances and activity levels in our MPP Advantage. However, borrowing patterns between our insurance company and depository members tend to differ during various economic and market conditions, thereby easing the potential magnitude of core business fluctuations during business cycles. Member demand for liquidity during stressed market conditions can lead to advances growth.

The decrease in net income for the three months ended September 30, 2018 compared to the corresponding period in the prior year was primarily due to higher net losses on derivatives and hedging activities and, to a lesser extent, higher operating expenses, partially offset by higher net interest income.

The increase in net income for the nine months ended September 30, 2018 compared to the corresponding period in the prior year was primarily due to a net realized gain on the sale of all of the Bank's private-label RMBS and ABS, higher net interest income and lower net losses on derivatives and hedging activities, partially offset by higher operating expenses.

The increase in total assets at September 30, 2018 compared to December 31, 2017 was primarily driven by an increase in short-term investments outstanding to enhance the Bank's liquidity position in light of the issuance of new regulatory guidance from the Finance Agency. See Recent Accounting and Regulatory Developments - Legislative and Regulatory Developments for additional information. The increase in total liabilities at September 30, 2018 compared to December 31, 2017 was attributable to a net increase in consolidated obligations to support the increase in the Bank's assets.

The increase in total capital at September 30, 2018 compared to December 31, 2017 was primarily a result of the growth of retained earnings and additional capital stock issued to members. These increases were partially offset by the reduction in AOCI as a result of the recognition of the gain on the sale of our private-label RMBS and ABS.

⁽¹⁾  Annualized. 

⁽²⁾  Consists of AFS and HTM securities. The average balances of investment securities are based on amortized cost; therefore, the resulting yields do not reflect changes in the estimated fair value of AFS securities that are a component of OCI, nor do they reflect OTTI-related non-credit losses. Interest income/expense includes the effects of associated derivative transactions.

⁽³⁾  Interest income/expense and average yield include all other components of interest, including the impact of net interest payments or receipts on derivatives in qualifying hedge relationships, amortization of hedge accounting adjustments, and prepayment fees on advances.

⁽⁴⁾  Consists of interest-bearing deposits and loans to other FHLBanks (if applicable). Includes the rights or obligations to cash collateral, except for variation margin payments characterized as daily settled contracts. The 2017 amounts also include grantor trust assets that are included in other assets in 2018.

⁽⁵⁾  Includes changes in the estimated fair value of AFS securities and the effect of OTTI-related non-credit losses on AFS and HTM securities.

⁽⁶⁾ Annualized net interest income expressed as a percentage of the average balance of interest-earning assets.

The increase in net interest income for the three and nine months ended September 30, 2018 compared to the corresponding period in 2017 was primarily due to asset growth.

Yields. The average yield on total interest-earning assets for the three months ended September 30, 2018 was 2.54%, an increase of 75 bps compared to the corresponding period in 2017, resulting primarily from increases in market interest rates that led to higher yields on advances and investment securities. The average cost of total interest-bearing liabilities was 2.21%, an increase of 80 bps due to higher funding costs on consolidated obligations. The net effect was a decrease in the net interest spread to 0.33% for the three months ended September 30, 2018 from 0.38% for the corresponding period in 2017.

The average yield on total interest-earning assets for the nine months ended September 30, 2018 was 2.36%, an increase of 69 bps compared to the corresponding period in 2017, resulting primarily from increases in market interest rates that led to higher yields on advances and investment securities. The average cost of total interest-bearing liabilities was 2.01%, an increase of 72 bps due to higher funding costs on consolidated obligations. The net effect was a decrease in the net interest spread to 0.35% for the nine months ended September 30, 2018 from 0.38% for the corresponding period in 2017.

Average Balances. The average balances of all interest-earning assets for the three and nine months ended September 30, 2018 increased compared to the corresponding periods in 2017. The average balance of short-term investments outstanding for the three and nine months ended September 30, 2018 increased by 39% and 14%, respectively, in light of the issuance of new regulatory guidance from the Finance Agency. The average balance of advances outstanding for the three and nine months ended September 30, 2018 increased by 2% and 8%, respectively, generally driven by member funding needs. The average balance outstanding of mortgage loans held for portfolio for the three and nine months ended September 30, 2018 increased by 11% and 10%, respectively, due to strong demand by our members for MPP Advantage. The increase in average interest-bearing liabilities was due to an increase in consolidated obligations to fund the increases in the average balances of all interest-earning assets.

Provision for Credit Losses. The changes in the provision for credit losses for the three and nine months ended September 30, 2018 compared to the corresponding periods in 2017 were insignificant.

Other Income (Loss).The following table presents a comparison of the components of other income ($ amounts in millions).

The increase in total other loss for the three months ended September 30, 2018 compared to the corresponding period in 2017 was primarily due to higher net losses on derivatives and hedging activities. The increase in total other income for the nine months ended September 30, 2018 compared to the corresponding period in 2017 was primarily due to the gain on the sale of all of our private-label RMBS and ABS. See Notes to Financial Statements - Note 4 - Available-for-Sale Securitiesand Note 5 - Held-to-Maturity Securitiesfor additional information.

Net Gains (Losses) on Derivatives and Hedging Activities. For the hedging relationships that qualified for hedge accounting, the differences between the change in the estimated fair value of the hedged items and the change in the estimated fair value of the associated interest-rate swaps, i.e., hedge ineffectiveness, resulted in a net loss of $6 million and a net gain$1 million for the three and nine months ended September 30, 2018, respectively, compared to a net loss of $3 million and $11 million for the corresponding periods in 2017. Nearly all of these gains and losses will generally reverse over the remaining contractual terms of the hedged items. See Notes to Financial Statements - Note 11 - Derivatives and Hedging Activities in our 2017 Form 10-K.

45

To the extent those hedges did not qualify for hedge accounting, or ceased to qualify because they were determined to be ineffective, only the change in the fair value of the derivative was recorded in earnings with no offsetting change in the fair value of the hedged item. For the derivatives not qualifying for hedge accounting (economic hedges), the net interest settlements and the changes in the estimated fair value of the derivatives were recorded in net gains (losses) on derivatives and hedging activities. For economic hedges, the Bank recorded a net loss of less than $1 million and $2 million for the three and nine months ended September 30, 2018, respectively, compared to a net loss of $1 million and $2 million for the corresponding periods in 2017.

The tables below present the net effect of derivatives on net interest income and other income (loss), within the net gains (losses) on derivatives and hedging activities, by type of hedge and hedged item ($ amounts in millions).

Other Expenses. The following table presents a comparison of the components of other expenses ($ amounts in millions).

	Three Months Ended September 30,				Nine Months Ended September 30,
Components	2018		2017		2018		2017
Compensation and benefits	$	12	$	11	$	38	$	33
Other operating expenses	8		7		21		19
Finance Agency and Office of Finance expenses	2		1		6		5
Other	1		1		4		2
Total other expenses	$	23	$	20	$	69	$	59

The increase in total other expenses for the three and nine months ended September 30, 2018 compared to the corresponding periods in 2017 was primarily due to increases in compensation, primarily driven by salary increases and higher head count. The increase for the nine months ended September 30, 2018 was also due to an increase in benefits expense.

Total Other Comprehensive Income (Loss). Total OCI for the three months ended September 30, 2018 and the three and nine months ended September 30, 2017 consisted substantially of unrealized gains on non-OTTI AFS securities. Total OCI for the nine months ended September 30, 2018 consisted substantially of the reduction in AOCI as a result of the recognition of the gain on the sale of our private-label RMBS and ABS.

Operating Segments

Our products and services are grouped within two operating segments:traditional and mortgage loans.

Traditional. The traditional segment consists of (i) credit products (including advances, letters of credit, and lines of credit), (ii) investments (including federal funds sold, securities purchased under agreements to resell, AFS securities and HTM securities), and (iii) correspondent services and deposits. The following table presents the financial performance of our traditional segment ($ amounts in millions). 

	Three Months Ended September 30,						Nine Months Ended September 30,
Traditional	2018			2017			2018		2017
Net interest income	$	57		$	52		$	163	$	140
Provision for credit losses	—			—			—		—
Other income (loss)	(6		)	(2		)	31		(9		)
Other expenses	20			17			59		50
Income before assessments	31			33			135		81
AHP assessments	3			4			14		9
Net income	$	28		$	29		$	121	$	72

The decrease in net income for the traditional segment for the three months ended September 30, 2018 compared to the corresponding period in 2017 was primarily due to higher net losses on derivatives and hedging activities and, to a lesser extent, higher operating expenses, partially offset by higher net interest income.

The increase in net income for the traditional segment for the nine months ended September 30, 2018 compared to the corresponding period in 2017 was primarily due to the net realized gain on the sale of all of the Bank's private-label RMBS and ABS, higher net interest income, primarily due to an increase in the average balances of advances outstanding, and lower net losses on derivatives and hedging activities, partially offset by higher operating expenses.

48

Mortgage Loans. The mortgage loans segment includes (i) mortgage loans purchased from our members through our MPP and (ii) participating interests purchased in 2012 - 2014 from the FHLBank of Topeka in mortgage loans originated by certain of its PFIs under the MPF Program. The following table presents the financial performance of our mortgage loans segment ($ amounts in millions). 

	Three Months Ended September 30,						Nine Months Ended September 30,
Mortgage Loans	2018			2017			2018			2017
Net interest income	$	16		$	17		$	50		$	52
Provision for (reversal of) credit losses	—			—			—			—

Income before assessments	12			13			39			42
AHP assessments	1			1			4			4
Net income	$	11		$	12		$	35		$	38

The decrease in net income for the mortgage loans segment for the three and nine months ended September 30, 2018 compared to the corresponding periods in 2017 was due to lower net interest income, due primarily to lower interest spreads.

Total assets	$	66,472	100	%	$	62,349	100	%

⁽¹⁾  Includes accrued interest receivable, premises, software and equipment, derivative assets and other miscellaneous assets.

Total assets were $66.5 billion as of September 30, 2018, a net increase of $4.1 billion or 7% compared to December 31, 2017, driven primarily by a significant increase in short-term investments to enhance the Bank's liquidity position in light of the issuance of new regulatory guidance from the Finance Agency. Such increase resulted in a change to the mix of our total assets.

Advances. Advances at carrying value totaled $33.6 billion at September 30, 2018, a net decrease of $488 million or 1% compared to December 31, 2017. This decrease was primarily due to a decline in short-term advances outstanding.

Advances to depository members - comprising commercial banks, savings institutions and credit unions - decreased by 5%. Advances to insurance company members increased by 3%. As a result, advances to depository institutions, as a percent of total advances outstanding, decreased from 55% at December 31, 2017 to 53% at September 30, 2018, while advances to insurance companies increased from 45% to 47% at those dates.

The table below presents advances outstanding by interest-rate payment terms ($ amounts in millions).

	September 30, 2018				December 31, 2017
Interest-Rate Payment Terms	Par Value		% of Total		Par Value		% of Total
Fixed-rate	$	24,976	74	%	$	25,133	73	%
Variable-rate	8,861		26	%	9,036		27	%
Total advances	$	33,837	100	%	$	34,169	100	%

Our advance portfolio includes callable or prepayable and putable advances. For prepayable advances, the advance can be prepaid on specified dates without incurring repayment or termination fees. All other advances may only be prepaid by the borrower paying a fee that is sufficient to make us financially indifferent to the prepayment of the advance. Ignoring lockout dates, callable or prepayable advances totaled $8.8 billion, or 26%, and $8.9 billion, or 26%, of advances outstanding, at par, at September 30, 2018 and December 31, 2017, respectively.

Advances due in one year or less decreased from 50% of the total outstanding, at par, at December 31, 2017 to 48% of the total outstanding, at par, at September 30, 2018, reflecting members' decreased demand for short-term funding. See Note 6 - Advances for additional information.

Mortgage Loans Held for Portfolio.A breakdown of mortgage loans held for portfolio by primary product type is presented below ($ amounts in millions).

	September 30, 2018				December 31, 2017
Product Type	UPB		% of Total		UPB		% of Total
MPP:
Conventional Advantage	$	9,731	88	%	$	8,608	85	%
Conventional Original	720		6	%	850		8	%
FHA	323		3	%	361		4	%
Total MPP	10,774		97	%	9,819		97	%
MPF Program:
Conventional	215		2	%	243		2	%
Government	56		1	%	62		1	%
Total MPF Program	271		3	%	305		3	%
Total mortgage loans held for portfolio	$	11,045	100	%	$	10,124	100	%

The increase in the UPB of mortgage loans held for portfolio was due to purchases under MPP Advantage exceeding repayments of outstanding MPP and MPF Program loans. Over time, the outstanding balance of mortgage loans purchased under our original MPP and the MPF Program will continue to decrease as all purchases are now under MPP Advantage.

We have established and maintain an allowance for loan losses based on our best estimate of probable losses over the loss emergence period, which we have estimated to be 24 months. Our estimate of MPP losses remaining after borrower's equity, but before credit enhancements, was $4 million at September 30, 2018 and $5 million at December 31, 2017. After consideration of the portion recoverable under the associated credit enhancements, the resulting allowance for MPP loan losses was less than $1 million at September 30, 2018 and December 31, 2017, respectively. For more information, see Notes to Financial Statements - Note 9 - Allowance for Credit Lossesin our 2017 Form 10-K.

During the third quarters of 2017 and 2018, major hurricanes caused substantial damage to property in several states on the southeastern coasts of the United States. We analyzed the potential impact of the hurricanes on the Bank’s mortgage loans held for portfolio, including the allowance for loan losses. Because all or a portion of any incurred losses would be covered by the credit enhancements in place and because there is no concentration of the Bank's loans in the affected states, we did not record any additional allowance for loan losses as of September 30, 2018, and we do not expect that any net losses resulting from the hurricanes will have a material effect on the Bank’s financial condition or results of operations.

Total cash and investments, carrying value	$	21,296	$	17,628	$	3,668

Cash and Short-Term Investments.Cash andshort-term investments totaled $8.1 billion at September 30, 2018, an increase of 75% compared to December 31, 2017, due to the Bank's enhancement of its liquidity position in light of the issuance of new regulatory guidance from the Finance Agency. Cash and short-term investments as a percent of total assets were 12% at September 30, 2018 compared to 7% at December 31, 2017.

Investment Securities.During the nine months ended September 30, 2018, for strategic, economic and operational reasons, we sold all of our private-label RMBS and ABS.

AFS securities totaled $7.4 billion at September 30, 2018, a net increase of 4% compared to $7.1 billion at December 31, 2017. The increase resulted from purchases of GSE MBS to maintain a ratio of MBS and ABS to total regulatory capital of up to 300%.

Net unrealized gains on AFS securities totaled $112 million at September 30, 2018, a decrease of $10 million compared to December 31, 2017, primarily due to changes in interest rates, credit spreads and volatility.

HTM securities totaled $5.8 billion at September 30, 2018, relatively unchanged from a total of $5.9 billion at December 31, 2017. At September 30, 2018, the estimated fair value of our HTM securities totaled $5.8 billion, of which $2.1 billion was in an unrealized loss position, a decrease of 26% from $2.8 billion at December 31, 2017, primarily due to changes in interest rates, credit spreads and volatility. The associated unrealized losses increased from $12 million at December 31, 2017 to $23 million at September 30, 2018.

Total HTM securities	$	5,811	100	%	$	5,898	100	%

The mix of fixed- vs. variable-rate securities at September 30, 2018 was slightly different compared to December 31, 2017, primarily due to the sale of our private-label RMBS. In addition, substantially all of the fixed-rate AFS securities are swapped to effectively create variable-rate securities, consistent with our balance sheet strategies to manage interest-rate risk.

Total Liabilities. Total liabilities were $63.4 billion at September 30, 2018, a net increase of 7% compared to December 31, 2017, substantially due to an increase in consolidated obligations.

Deposits (Liabilities). Total deposits were $484 million at September 30, 2018, a net decrease of 14% compared to December 31, 2017. These deposits represent a relatively small portion of our funding. The balances of these accounts can fluctuate from period to period and vary depending upon such factors as the attractiveness of our deposit pricing relative to the rates available on alternative money market instruments, members' preferences with respect to the maturity of their investments, and members' liquidity.

Consolidated Obligations.The carrying value of consolidated obligations outstanding at September 30, 2018 totaled $62.2 billion, a net increase of $4.0 billion or 7% from December 31, 2017. This increase supported the increase in the Bank's assets.

The following table presents a breakdown by term of our consolidated obligations outstanding ($ amounts in millions).

Total consolidated obligations	$	62,456	100	%	$	58,377	100	%

We maintain a liquidity and funding balance between our financial assets and financial liabilities. Additionally, the FHLBanks work collectively to manage FHLB System-wide liquidity and funding and jointly monitor System-wide refinancing risk. In managing and monitoring the amounts of assets that require refunding, the FHLBanks may consider contractual maturities of the financial assets, as well as certain assumptions regarding expected cash flows (i.e., estimated prepayments and scheduled amortizations). See Notes to Financial Statements - Note 3 - Available-for-Sale Securities, Note 6 - Advances, and Note 10 - Consolidated Obligations for more detailed information regarding contractual maturities of certain of our financial assets and liabilities.

Derivatives.The volume of derivative hedges is often expressed in terms of notional amounts, which is the amount upon which interest payments are calculated. The following table presents the notional amounts by type of hedged item whether or not it is in a qualifying hedge relationship ($ amounts in millions).

Hedged Item	September 30, 2018		December 31, 2017
Advances	$	13,613	$	11,296
Investments	8,429		7,238
Mortgage loans	798		144
CO bonds	14,984		13,524
Discount notes	—		298
Total notional	$	37,824	$	32,500

Total Capital. Total capital at September 30, 2018 was $3.1 billion, a net increase of $111 million or 4% compared to December 31, 2017. This increase was primarily a result of the growth of retained earnings and additional capital stock issued to members. These increases were partially offset by the reduction in AOCI as a result of the recognition of the gain on the sale of our private-label RMBS and ABS.

The following table presents a percentage breakdown of the components of GAAP capital.

Components	September 30, 2018		December 31, 2017
Capital stock	62	%	63	%
Retained earnings	35	%	33	%
AOCI	3	%	4	%
Total GAAP capital	100	%	100	%

The components of GAAP capital were relatively unchanged at September 30, 2018 compared to December 31, 2017.

The following table presents a reconciliation of GAAP capital to regulatory capital ($ amounts in millions).

Reconciliation	September 30, 2018			December 31, 2017
Total GAAP capital	$	3,057		$	2,946
Exclude: AOCI	(95		)	(112		)
Add: MRCS	164			164
Total regulatory capital	$	3,126		$	2,998

Liquidity and Capital Resources

Liquidity.Our primary sources of liquidity are holdings of cash and short-term investments and the issuance of consolidated obligations. Our cash and short-term investments portfolio totaled $8.1 billion at September 30, 2018. During the nine months ended September 30, 2018, we maintained sufficient access to funding; our net proceeds from the issuance of consolidated obligations totaled $267.3 billion.

The recent issuance of new regulatory guidance by the Finance Agency could continue to significantly increase the amount and change the characteristics of liquidity that we are required to maintain. We have not identified any other trends, demands, commitments, or events that are likely to materially increase or decrease our liquidity.

Changes in Cash Flow. Net cash provided by operating activities was $427 million for the nine months ended September 30, 2018, compared to $202 million for the nine months ended September 30, 2017. The increase was primarily due to the impact of the change in the legal characterization of variation margin payments to be daily settled contracts.

54

Capital Resources.

Total Regulatory Capital. A breakdown of our outstanding capital stock, categorized by type of member institution, and MRCS is provided in the following table ($ amounts in millions).

	September 30, 2018				December 31, 2017
By Type of Member Institution	Amount		% of Total		Amount		% of Total

Total MRCS	164		8	%	164		8	%
Total regulatory capital stock	$	2,065	100	%	$	2,022	100	%

⁽¹⁾  Memberships must terminate no later than February 19, 2021.

⁽²⁾  Balances at September 30, 2018 and December 31, 2017 include $1 million and $3 million, respectively, of MRCS that had reached the end of the five-year redemption period but will not be redeemed until the associated credit products and other obligations are no longer outstanding.

Excess Capital Stock.The following table presents the composition of our excess capital stock ($ amounts in millions).

Components	September 30, 2018			December 31, 2017
Member capital stock not subject to outstanding redemption requests	$	371		$	302
Member capital stock subject to outstanding redemption requests	5			4
MRCS	27			31
Total excess capital stock	$	403		$	337
Excess stock as a percentage of regulatory capital stock	20		%	17		%

The increase in excess stock during the nine months ended September 30, 2018 resulted primarily from the fluctuations in advances outstanding.

Finance Agency rules limit the ability of an FHLBank to issue excess stock under certain circumstances, including when its total excess stock exceeds 1% of total assets or if the issuance of excess stock would cause total excess stock to exceed 1% of total assets. Our excess stock at September 30, 2018 was 0.6% of our total assets. Therefore, subject to these regulatory limitations, we are currently permitted to issue new excess stock to members and distribute stock dividends, should we choose to do so.

Capital Distributions.On October 25, 2018, our board of directors declared a cash dividend of 4.50% (annualized) on our Class B-1 capital stock and 3.60% (annualized) on our Class B-2 capital stock.

55

Adequacy of Capital.We must maintain sufficient permanent capital to meet the combined credit risk, market risk and operations risk components of the risk-based capital requirement. As presented in the following table, we were in compliance with the risk-based capital requirement at September 30, 2018 and December 31, 2017 ($ amounts in millions).

Risk-Based Capital Components	September 30, 2018		December 31, 2017
Credit risk	$	314	$	360
Market risk	330		336
Operations risk	193		208
Total risk-based capital requirement	$	837	$	904
Permanent capital	$	3,126	$	2,998

The decrease in the total risk-based capital requirement was primarily caused by a decrease in the credit risk component as a result of the sale of our private-label RMBS portfolio. Our permanent capital at September 30, 2018 remained well in excess of our total risk-based capital requirement.

Off-Balance Sheet Arrangements

At September 30, 2018, principal previously paid in full by our MPP servicers totaling $2 million remains subject to potential claims by those servicers for any losses resulting from past or future liquidations of the underlying properties. An estimate of the losses is included in the MPP allowance for loan losses. For more information, see Notes to Financial Statements - Note 9 - Allowance for Credit Losses in our 2017 Form 10-K. For information on additional commitments and contingencies, seeNotes to Financial Statements - Note 16 - Commitments and Contingencies.

Critical Accounting Policies and Estimates

We determined that four of our accounting policies and estimates are critical because they require management to make particularly difficult, subjective, and/or complex judgments about matters that are inherently uncertain and because of the likelihood that materially different amounts could be reported under different conditions or using different assumptions. These accounting policies pertain to:

• Derivatives and hedging activities (see Notes to Financial Statements - Note 9 - Derivatives and Hedging Activitiesfor more detail);

• Fair value estimates (see Notes to Financial Statements - Note 15 - Estimated Fair Valuesfor more detail);

• Provision for credit losses (see Notes to Financial Statements - Note 8 - Allowance for Credit Lossesfor more detail); and

• OTTI (see Notes to Financial Statements - Note 5 - Other-Than-Temporary Impairmentfor more detail).

A full discussion of our critical accounting policies and estimates is included in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Estimates in our 2017 Form 10-K. See below for additional information regarding certain of these policies.

Provision for Credit Losses.

Mortgage Loans Acquired under the MPP. Our allowance for loan losses incorporates our analysis of delinquent conventional MPP loans, using the estimated fair value of the underlying collateral, further reduced by estimated liquidation costs.

As part of our loan loss analysis at December 31, 2017, we considered an adverse scenario whereby we used a haircut on our underlying collateral values of 20% for delinquent conventional loans, including individually evaluated loans. We consider such a haircut to represent the most distressed scenario that is reasonably possible to occur over the loss emergence period of 24 months. In this distressed scenario, while holding all other assumptions constant, our estimated incurred losses remaining after borrowers' equity, but before credit enhancements, would increase by approximately $3.1 million. However, such increase would be substantially offset by credit enhancements. Based upon subsequent changes in underlying collateral values, we would not expect this amount to have significantly changed at September 30, 2018. Therefore, the allowance for loan losses continues to be based upon our best estimate of the probable losses over the loss emergence period that would not be recovered from the credit enhancements.

56

Other-Than-Temporary Impairment.

During the nine months ended September 30, 2018, we sold all of our investments in private-label RMBS and ABS. Therefore, we did not have any OTTI-related credit losses recognized in earnings and did not run a more stressful scenario at September 30, 2018.

Recent Accounting and Regulatory Developments

Accounting Developments. See Notes to Financial Statements - Note 2 - Recently Adopted and Issued Accounting Guidance for a description of how recent accounting developments may impact our financial condition, results of operations or cash flows.

Legislative and Regulatory Developments.

Finance Agency Proposed Rule on Housing Goals Amendments. On November 2, 2018, the Finance Agency published proposed amendments to the FHLBank Housing Goals regulation. The proposed amendments would substantially revise the current regulation in several respects. Among other things, the proposed amendments would:

• Remove the current process by which the Finance Agency establishes each FHLBank’s housing goals retrospectively based on Home Mortgage Disclosure Act ("HMDA") data;

◦ Instead, the amendments would, within the regulation itself, prospectively establish annual housing goals for all FHLBanks.

• Eliminate the current regulation’s $2.5 billion annual AMA purchase volume threshold that triggers application of housing goals for each FHLBank;

• Eliminate the current regulation’s separate housing goals for home-purchase mortgages for low-income families, low-income areas, very-low income families and refinancing mortgages for low-income families;

◦ These four goals would be replaced by a single, overall measurement of performance. The new housing goal would include each of the four categories, but would not include a separate target level for each category. However, the proposed amendments would place a cap on the amount of purchased loans made to high-income borrowers in low-income areas by requiring that at least 75% of the mortgage loans counted toward the housing goal be made to low-income or very low-income families.

• Establish the prospective mortgage purchase housing goal target level at 20% of an FHLBank’s annual AMA mortgage purchases;

• Permit the FHLBanks to request Finance Agency approval of an alternative goal level;

• Establish a separate annual housing goal target level for AMA program participation (generally 50% of all PFIs) by smaller members (those with average asset sizes below the community financial institution cap established annually by the Finance Agency);

• Enable the Finance Agency to require any FHLBank that fails to meet any housing goal to perform a feasibility analysis on the FHLBank’s ability to meet that goal and, if the Finance Agency determines the goal was feasible, require the FHLBank to submit a housing plan detailing how it intends to achieve the goal during the next calendar year; and

• Establish a three-year phase-in for enforcement of the new housing goals.

We are studying the proposed amendments, but at this time we have not fully determined how the amendments, if adopted as proposed, will affect our Advantage MPP or impact our PFIs’ use of the program. Comments on the proposed amendments are due by January 31, 2019.

57

Liquidity Guidance Advisory Bulletin. On August 23, 2018, the Finance Agency issued Advisory Bulletin 2018-07 on FHLBank liquidity ("Liquidity Guidance AB"). The Liquidity Guidance AB communicates the Finance Agency’s expectations with respect to the maintenance of sufficient liquidity to enable the FHLBanks to provide advances and letters of credit for members for a specified time without access to the capital markets or other unsecured funding sources. Contemporaneously with the issuance of the Liquidity Guidance AB, the Finance Agency issued a supervisory letter that identifies initial thresholds for liquidity measures.The Liquidity Guidance AB rescinds the liquidity guidance issued by the Finance Agency in 2009.

The Liquidity Guidance AB provides guidance on the level of on-balance sheet liquid assets related to base case liquidity. As part of the base case liquidity measure, the guidance also includes a separate provision covering off-balance sheet commitments from standby letters of credit ("SLOCs"). In addition, the guidance addresses asset/liability maturity funding gap limits.

With respect to base case liquidity, the Finance Agency revised previous guidance that required the FHLBanks to assume a 5-day period without access to capital markets due to a change in certain assumptions underlying that guidance. Under the Liquidity Guidance AB, FHLBanks will be required to hold positive cash flow assuming no access to capital markets for an increased period of between ten and thirty calendar days, with a specific measurement period set forth in the supervisory letter. The guidance also sets forth the initial cash flow assumptions and formula to calculate base case liquidity. With respect to SLOCs, the guidance indicates that FHLBanks should maintain a liquidity reserve of between 1% and 20% of its outstanding SLOC commitments, as specified in the supervisory letter.

With respect to funding gaps and possible asset and liability mismatches, the Liquidity Guidance AB provides guidance on maintaining appropriate funding gaps for three-month (-10 to -20%) and one-year (-25 to -35%) maturity horizons. The guidance indicates that, depending on financial market conditions, maintaining gap limits within these ranges should provide reasonable assurance that an FHLBank will have adequate liquidity to address the risks associated with possible asset and liability maturity mismatches, including an undue reliance on short-term debt funding, which may increase debt rollover risk.

The Liquidity Guidance AB also addresses liquidity stress testing, contingency funding plans and an adjustment to each FHLBank’s core mission achievement calculation. Portions of the guidance will be implemented beginning on December 31, 2018, with further implementation on March 31, 2019, and full implementation on December 31, 2019. The Liquidity Guidance AB may require us to hold an additional amount of liquid assets, which may increase the cost of funding required to achieve the appropriate funding gap with longer-term funding. Moreover, this could reduce our ability to invest in higher-yielding assets. We do not believe these changes would materially impact our financial condition or results of operations.

Finance Agency Proposed Amendment to Rule Regarding Golden Parachute and Indemnification Payments. On August 28, 2018, the Finance Agency published proposed amendments to its rule on golden parachute payments ("Golden Parachute Rule") to better align the rule with areas of the Finance Agency’s supervisory concern and to reduce administrative and compliance burdens. The Golden Parachute Rule sets forth the standards that the Finance Agency would take into consideration when limiting or prohibiting golden parachute and indemnification payments by an FHLBank or the Office of Finance to an affiliated party (which includes any director, officer or employee) when such FHLBank or the Office of Finance is in troubled condition, in conservatorship or receivership, or insolvent. The proposed amendments would:

• Focus these standards on payments and agreements with executive officers, broad-based plans covering large numbers of employees and payments made to non-executive-officer employees who may have engaged in certain types of wrongdoings;

• Revise and clarify definitions, exemptions and procedures to implement the Finance Agency’s supervisory approach; and

• Align procedures and outcomes of review with requirements of the Finance Agency’s rule on executive compensation.

Comments on the proposed rule were due by October 12, 2018. Ten of the FHLBanks and the Office of Finance submitted a joint comment letter. We continue to assess the effect of the proposed amendments, but we do not anticipate that, if adopted, they would materially impact our financial condition or results of operations.

58

Final Rule on Indemnification Payments. On October 4, 2018, the Finance Agency published a final rule establishing standards for identifying when an indemnification payment by an FHLBank or the Office of Finance to an officer, director, employee, or other affiliated party in connection with an administrative proceeding or civil action instituted by the Finance Agency is prohibited or permissible. The rule generally prohibits these payments except in the following circumstances:

• Premiums for commercial insurance coverage or fidelity bonds for directors and officers, to the extent that the insurance or fidelity bond covers expenses and restitution, but not in connection with a judgment in favor of the Finance Agency or a civil money penalty imposed by the Finance Agency on the affiliated party;

• Expenses of defending an action, subject to (i) the board of directors conducting a due investigation and making a written determination that: (a) the affiliated party acted in good faith and in a manner that he or she reasonably believed to be in the best interest of the FHLBank or the Office of Finance (as the case may be) and (b) such payments will not materially adversely affect the safety and soundness of the FHLBank or the Office of Finance; and (ii) an agreement to repay those expenses in certain instances; and

• Amounts payable under an indemnification agreement entered into on or prior to September 20, 2016 (the date the rule was proposed).

The rule also outlines the process the board of directors must undertake prior to making a permitted payment. The rule became effective November 5, 2018. We do not expect the rule will materially impact our financial condition or results of operations or ability to recruit or retain directors.

Risk Management

We have exposure to a number of risks in pursuing our business objectives. These risks may be broadly classified as market, credit, liquidity, operational, and business. Market risk is discussed in Item 3. Quantitative and Qualitative Disclosures about Market Risk. See Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Risk Management in our 2017 Form 10-K for more information.

Credit Risk Management. We face credit risk on advances and other credit products, investments, mortgage loans, derivative financial instruments, and AHP grants.

Advances and Other Credit Products.As of September 30, 2018 and December 31, 2017, advances to our insurance company members represented 47% and 45%, respectively, of our total advances, at par. The initial borrowing limit for our insurance company members (excluding captive insurance companies) is 25% of their total general account assets less money borrowed. As of September 30, 2018, no insurance company member had total credit products outstanding in excess of this threshold.

Effective February 19, 2016, new or renewed credit extensions to captive insurance companies that became members prior to September 12, 2014 are subject to certain regulatory restrictions relating to maturity dates and cannot exceed 40% of the member's total assets. As of September 30, 2018, one such captive insurance company member's total credit products previously outstanding exceeded the percentage limit. Therefore, no new or renewed credit extensions have been made to this member. We may impose additional restrictions on extensions of credit to our members, including captive insurance companies, at our discretion.

Concentration. Our credit risk is magnified due to the concentration of advances in a few borrowers. As of September 30, 2018, our top borrower held 13% of total advances outstanding, at par, and our top five borrowers held 43% of total advances outstanding, at par. As a result of this concentration, we perform frequent credit and collateral reviews on our largest borrowers. In addition, we analyze the implications to our financial management and profitability if we were to lose the business of one or more of these borrowers.

59

Investments. We are also exposed to credit risk through our investment portfolios. Our policies restrict the acquisition of investments to high-quality, short-term money market instruments and high-quality long-term securities.

The following table presents the unsecured investment credit exposure to private counterparties, categorized by the domicile of the counterparty's ultimate parent, based on the lowest of the counterparty's NRSRO long-term credit ratings, stated in terms of the S&P equivalent.

A Finance Agency regulation provides that the total amount of our investments in MBS and ABS, calculated using amortized historical cost, must not exceed 300% of our total regulatory capital, as of the day we purchase the securities, based on the capital amount most recently reported to the Finance Agency. These investments totaled 293% of total regulatory capital at September 30, 2018. Generally, our goal is to maintain these investments near the 300% limit in order to enhance earnings and capital for our members and diversify our revenue stream.

The following table presents the carrying values of our investments, excluding accrued interest, grouped by credit rating and investment category. Applicable rating levels are determined using the lowest relevant long-term rating from S&P, Moody's and Fitch Ratings, Inc., each stated in terms of the S&P equivalent. Rating modifiers are ignored when determining the applicable rating level for a given counterparty or investment.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Measuring Market Risks

To evaluate market risk, we utilize multiple risk measurements, including duration of equity, duration gap, convexity, VaR, earnings at risk, and changes in MVE. Periodically, we conduct stress tests to measure and analyze the effects that extreme movements in the level of interest rates and the shape of the yield curve would have on our risk position.

Market Risk-Based Capital Requirement. When calculating the risk-based capital requirement, the VaR comprising the first factor of the market risk component is defined as the potential dollar loss from adverse market movements, for a holding period of 120 business days, with a 99% confidence interval, based on those historical prices and market rates. The table below presents the VaR ($ amounts in millions).

Date	VaR
September 30, 2018	$	330
December 31, 2017	336

Certain Market and Interest-Rate Risk Metrics under Potential Interest-Rate Scenarios. We also monitor the sensitivities of MVE and duration of equity to potential interest-rate scenarios. We measure potential changes in the market value to book value of equity based on the current month-end level of rates versus large parallel rate shifts. The following table presents certain market and interest-rate metrics under different interest-rate scenarios ($ amounts in millions).

September 30, 2018	Down 200 (1)			Down 100 (1)			Base			Up 100			Up 200

⁽¹⁾  Given the low interest rates in the short-to-medium term points of the yield curves, downward rate shocks are constrained to prevent rates from becoming negative.

⁽²⁾  The change in the base MVE/book value of equity from December 31, 2017 resulted primarily from the change in market value of the assets and liabilities in response to changes in the market environment and changes in portfolio composition.

⁽³⁾  We use interest-rate shocks in 50 bps increments to determine duration of equity.

Duration Gap. The base case duration gap was 0.08% and 0.10% at September 30, 2018 and December 31, 2017, respectively.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We are responsible for establishing and maintaining disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in our reports filed under the Securities Exchange Act of 1934, as amended ("Exchange Act") is: (a) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms; and (b) accumulated and communicated to our management, including our principal executive officer, principal financial officer, and principal accounting officer, to allow timely decisions regarding required disclosures. As of September 30, 2018, we conducted an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer (the principal executive officer), Chief Financial Officer (the principal financial officer), and Chief Accounting Officer (the principal accounting officer), of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15 of the Exchange Act. Based on that evaluation, our Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer concluded that our disclosure controls and procedures were effective as of September 30, 2018.

Internal Control Over Financial Reporting

Changes in Internal Control Over Financial Reporting.There were no changes in our internal control over financial reporting, as defined in rules 13a-15(f) and 15(d)-15(f) of the Exchange Act, that occurred during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls.We do not expect that our disclosure controls and procedures and other internal controls will prevent all error and fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty and breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can only be reasonable assurance that any design will succeed in achieving its stated goals under all potential future conditions. Additionally, over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Part II. OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

In the ordinary course of business, we may from time to time become a party to lawsuits involving various business matters. We are unaware of any lawsuits presently pending which, individually or in the aggregate, could have a material effect on our financial condition or results of operations.

Item 1A. RISK FACTORS

There have been no material changes in the risk factors described in Item 1A. Risk Factors of our 2017 Form 10-K.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 1 - Summary of Significant Accounting Policies

We use acronyms and terms throughout these notes to financial statements that are defined herein or in the Glossary of Terms. Unless the context otherwise requires, the terms "Bank," "we," "us," and "our" refer to the Federal Home Loan Bank of Indianapolis or its management.

Basis of Presentation. The accompanying interim financial statements have been prepared in accordance with GAAP and SEC requirements for interim financial information. Accordingly, they do not include all of the information and disclosures required by GAAP for complete financial statements. Certain disclosures that would have substantially duplicated the disclosures in the financial statements, and notes thereto, included in our 2017 Form 10-K have been omitted unless the information contained in those disclosures materially changed. Therefore, these interim financial statements should be read in conjunction with our audited financial statements, and notes thereto, included in our 2017 Form 10-K.

The financial statements contain all adjustments that are, in the opinion of management, necessary for a fair statement of our financial position, results of operations and cash flows for the interim periods presented. All such adjustments were of a normal recurring nature. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full calendar year or any other interim period.

Our significant accounting policies and certain other disclosures are set forthin our 2017 Form 10-K in Note 1 - Summary of Significant Accounting Policies. There have been no significant changes to these policies through September 30, 2018. However, see Note 2 - Recently Adopted and Issued Accounting Guidance.

Use of Estimates.When preparing financial statements in accordance with GAAP, we are required to make subjective assumptions and estimates that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expense. The most significant estimates pertain to derivatives and hedging activities, fair value, the provision for credit losses, and OTTI. Although the reported amounts and disclosures reflect our best estimates, actual results could differ significantly from these estimates.

Reclassifications. We have reclassified certain amounts from the prior period to conform to the current period presentation. These reclassifications had no effect on total assets, total liabilities, total capital, net income, total comprehensive income, or net cash flows.

Recently Adopted and Issued Accounting Guidance

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recently Adopted and Issued Accounting Guidance

Note 2 - Recently Adopted and Issued Accounting Guidance

Recently Adopted Accounting Guidance.

Revenue from Contracts with Customers (ASU 2014-09). On May 28, 2014, the FASB issued guidance on revenue from contracts with customers. This guidance outlines a comprehensive model for recognizing revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry specific guidance. In addition, this guidance amends the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are not in a contract with a customer. This guidance applies to all contracts with customers except those that are within the scope of certain other standards, such as financial instruments, certain guarantees, insurance contracts, or lease contracts.

The guidance, which included subsequent amendments, was effective for our interim and annual periods beginning on January 1, 2018. The adoption of this guidance had no effect on our financial condition, results of operations, or cash flows.

Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01). On January 5, 2016, the FASB issued amended guidance on certain aspects of recognition, measurement, presentation, and disclosure of financial instruments.

The guidance was effective for our interim and annual periods beginning on January 1, 2018. The adoption of this guidance had no effect on our financial condition, results of operations, or cash flows.

Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15). On August 26, 2016, the FASB issued amendments intended to reduce diversity in practice in how cash receipts and cash payments are presented and classified on the statement of cash flows for certain transactions.

These amendments were adopted on a retrospective basis effective beginning on January 1, 2018. As a result, the amount of interest payments as reported in the supplemental disclosures increased for the nine months ended September 30, 2017 by $101,253. The adoption of these amendments had no effect on our financial condition, results of operations or cash flows.

Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (ASU 2017-07). On March 10, 2017, the FASB issued amendments to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The amendments require that an employer disaggregate the service cost component from the other components of net pension and benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement.

These amendments were effective for our interim and annual periods beginning on January 1, 2018. The adoption of these amendments had no effect on our financial condition, results of operations, or cash flows. However, the amendments were applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost on the income statement, which resulted in a reclassification from compensation and benefits to other expenses for the non-service components for the three and nine months ended September 30, 2017 of $526 and $1,500, respectively.

Recently Issued Accounting Guidance.

Leases (ASU 2016-02). On February 25, 2016, the FASB issued guidance which requires recognition of lease assets and lease liabilities on the statement of condition and disclosure of key information about leasing arrangements. In particular, this guidance requires a lessee, in an operating or finance lease, to recognize on the statement of condition a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. However, for a lease with a term of 12 months or less, a lessee is permitted to make an accounting policy election not to recognize a lease asset and lease liability. Under previous guidance, a lessee was not required to recognize a lease asset and lease liability arising from an operating lease on the statement of condition. While this guidance does not fundamentally change lessor accounting, some changes have been made to align that guidance with the lessee guidance and other areas within GAAP.

This guidance is effective for the interim and annual periods beginning on January 1, 2019. As amended, the guidance allows lessors and lessees to recognize and measure leases at the adoption date by recognizing a cumulative-effect adjustment directly to retained earnings. Upon adoption, we will report higher assets and liabilities as a result of including right-of-use assets and lease liabilities on the statement of condition, but its effect on our financial condition, results of operations, and cash flows would not currently be material.

Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12). On August 28, 2017, the FASB issued amended guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. This guidance requires that, for fair value hedges, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness be presented in the same income statement line that is used to present the earnings effect of the hedged item. For cash flow hedges, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness must be recorded in OCI. In addition, the amendments include certain targeted improvements to the assessment of hedge effectiveness and permit, among other things, the following:

• Measurement of the change in fair value of the hedged item on the basis of the benchmark rate component of the contractual coupon cash flows determined at hedge inception.

• Measurement of the hedged item in a partial-term fair value hedge of interest-rate risk by assuming the hedged item has a term that reflects only the designated cash flows being hedged.

• Consideration only of how changes in the benchmark interest rate affect a decision to settle a prepayable instrument before its scheduled maturity in calculating the change in the fair value of the hedged item attributable to interest-rate risk.

This guidance is effective beginning January 1, 2019. Its adoption would currently have no effect on our financial condition, results of operations, or cash flows. However, the amended presentation and disclosure guidance will result in a prospective reclassification on the income statement of the change in fair value of hedging instruments and related hedged items in fair value hedging relationships from other income to interest income.

Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). On August 28, 2018, the FASB issued guidance to update the disclosure requirements for fair value measurement. These amendments were issued as part of the FASB's disclosure framework project and are intended to improve disclosure effectiveness.

The guidance is effective for annual periods beginning on January 1, 2020, and early adoption is permitted; however, we currently plan to adopt this guidance on the effective date. The adoption may have an effect on our disclosures, but will not have any effect on our financial condition, results of operations, or cash flows.

Changes to the Disclosure Requirements for Defined Benefit Plans (ASU 2018-14). On August 28, 2018, the FASB issued guidance to modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. These amendments were issued as part of the FASB's disclosure framework project and are intended to improve disclosure effectiveness.

The guidance is effective for the annual period ended December 31, 2020, and early adoption is permitted; however, we currently plan to adopt this guidance on the effective date. The adoption may have an effect on our disclosures, but will not have any effect on our financial condition, results of operations, or cash flows.

Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (ASU 2018-15). On August 29, 2018, the FASB issued guidance on implementation costs incurred in a hosting arrangement as a service contract. The amendments align the requirements for capitalizing such costs with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software and hosting arrangements that include an internal-use software license.

This guidance becomes effective for interim and annual periods beginning on January 1, 2020, and early adoption is permitted; however, we currently plan to adopt this guidance on the effective date. We are in the process of evaluating this guidance, but we currently do not expect its effect on our financial condition, results of operations, or cash flows to be material.

Inclusion of the Secured Overnight Financing Rate (SOFR) OIS Rate as a Benchmark Interest Rate for Hedge Accounting Purposes (ASU 2018-16). On October 25, 2018, to facilitate the LIBOR to SOFR transition, the FASB issued guidance permitting the OIS rate based on SOFR as an eligible U.S. benchmark interest rate for hedge accounting purposes.

This guidance becomes effective for interim and annual periods beginning on January 1, 2019, concurrent with the adoption of ASU 2017-12. We are in the process of evaluating the impact that this guidance may have on our hedging strategies, but we currently do not expect its effect on our financial condition, results of operations, or cash flows to be material.

Contractual Maturity.The amortized cost and estimated fair value of non-MBS AFS securities are presented below by contractual maturity. MBS are not presented by contractual maturity because their actual maturities will likely differ from their contractual maturities as borrowers have the right to prepay their obligations with or without prepayment fees.

Total AFS securities	$	7,318,493	$	7,430,027	$	7,006,917	$	7,128,758

Realized Gains and Losses. During the nine months ended September 30, 2018, for strategic, economic and operational reasons, we sold all of our AFS and HTM investments in private-label RMBS and ABS. Of the OTTI AFS securities sold in 2018, none were in an unrealized loss position. Proceeds from the AFS sales totaled $203,841, resulting in realized gains of $32,407 determined by the specific identification method. There were no sales during the three or nine months ended September 30, 2017.

As of September 30, 2018, we had no intention of selling any AFS securities in an unrealized loss position nor did we consider it more likely than not that we will be required to sell these securities before our anticipated recovery of each security's remaining amortized cost basis.

⁽¹⁾  For private-label ABS, at December 31, 2017, the total of unrealized losses does not agree to total gross unrecognized holding losses of $405. Total unrealized losses include non-credit-related OTTI losses recorded in AOCI of $51 and gross unrecognized holding gains on previously OTTI securities of $40.

Realized Gains and Losses. During the nine months ended September 30, 2018, for strategic, economic and operational reasons, we sold all of our AFS and HTM investments in private-label RMBS and ABS. The amortized cost of the HTM securities sold totaled $41,271. Proceeds from the HTM sales totaled $41,226, resulting in realized losses of $45 determined by the specific identification method. For each of these HTM securities, we had previously collected at least 85% of the principal outstanding at the time of acquisition due to prepayments or scheduled payments over the term. As such, the sales were considered maturities for purposes of security classification. There were no sales of HTM securities during the three or nine months ended September 30, 2017.

As of September 30, 2018, we had no intention of selling any HTM securities in an unrealized loss position nor did we consider it more likely than not that we will be required to sell these securities before our anticipated recovery of each security's remaining amortized cost basis.

OTTI Evaluation Process and Results - Private-label RMBS and ABS.

Results of OTTI Evaluation Process - Private-label RMBS and ABS. As part of our evaluation for the three months ended March 31, 2018, we did not have any change in intent to sell, nor were we required to sell, any OTTI security. Therefore, we performed a cash flow analysis at that time to determine whether we expected to recover the entire amortized cost of each security. As a result of that cash flow analysis, no OTTI credit losses were recognized. At that time, we determined that the unrealized losses on the remaining private-label RMBS and ABS were temporary as we expected to recover the entire amortized cost.

During the nine months ended September 30, 2018, for strategic, economic and operational reasons, we sold all of our investments in private-label RMBS and ABS. The following table presents a rollforward of the amounts related to credit losses recognized in earnings.

For other U.S. obligations, GSE obligations, and TVA debentures, we determined that, based on current expectations, the strength of the issuers' guarantees through direct obligations of or support from the United States government is sufficient to protect us from any losses. As a result, all of the gross unrealized losses as of September 30, 2018 are considered temporary.

Credit Risk Exposure and Security Terms. At September 30, 2018 and December 31, 2017, our top five borrowers held 43% and 45%, respectively, of total advances outstanding, at par. As security for the advances to these and our other borrowers, we held, or had access to, collateral with an estimated fair value at September 30, 2018 and December 31, 2017 that was well in excess of the advances outstanding on those dates, respectively.

⁽¹⁾  The recorded investment in a loan is the UPB of the loan, adjusted for accrued interest, net of any deferred loan fees or costs, unamortized premiums or discounts (which may include the basis adjustment related to any gain or loss on a delivery commitment prior to being funded) and direct charge-offs. The recorded investment is not net of any valuation allowance.

⁽²⁾  Includes loans for which the decision of foreclosure or similar alternative, such as pursuit of deed-in-lieu of foreclosure, has been reported. Loans in process of foreclosure are included in past due categories depending on their delinquency status, but are not necessarily considered to be on non-accrual status.

⁽³⁾  Represents loans 90 days or more past due (including loans in process of foreclosure) expressed as a percentage of the total recorded investment in mortgage loans. The percentage excludes principal and interest amounts previously paid in full by the servicers on conventional loans that are pending resolution of potential loss claims. Our servicers repurchase seriously delinquent government loans, including FHA loans, when certain criteria are met.

⁽⁴⁾  Although our past due scheduled/scheduled MPP loans are classified as loans past due 90 days or more based on the loan's delinquency status, we do not consider these loans to be on non-accrual status.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities

Note 9 - Derivatives and Hedging Activities

Managing Credit Risk on Derivatives. We are subject to credit risk due to the risk of nonperformance by the counterparties to our derivative transactions.

Uncleared Derivatives. For certain of our uncleared derivatives, we have credit support agreements that contain provisions requiring us to post additional collateral with our counterparties if there is deterioration in our credit rating. If our credit rating is lowered by an NRSRO, we could be required to deliver additional collateral on uncleared derivative instruments in net liability positions. The aggregate estimated fair value of all uncleared derivative instruments with credit-risk-related contingent features that were in a net liability position (before cash collateral and related accrued interest on cash collateral) at September 30, 2018 was $599, for which we were not required to post collateral. If our credit rating had been lowered by an NRSRO (from an S&P equivalent of AA+ to AA), we would not have been required to deliver additional collateral to our uncleared derivative counterparties at September 30, 2018.

Cleared Derivatives. The clearinghouse determines margin requirements, which are generally not based on credit ratings. However, clearing agents may require additional margin to be posted by us based on credit considerations, including but not limited to any credit rating downgrades. At September 30, 2018, we were not required by our clearing agents to post any additional margin.

Financial Statement Effect and Additional Financial Information.

Derivative Notional Amounts. We record derivative instruments, related cash collateral received or pledged/posted and associated accrued interest on a net basis, by clearing agent and/or by counterparty when the netting requirements have been met. The following table presents the notional amount and estimated fair value of derivative assets and liabilities.

Note 12 - Capital

Stock Redemption and Repurchase. Through September 30, 2018, certain members had requested redemptions of their Class B stock, but the related stock outstanding at September 30, 2018 and December 31, 2017 totaling $5,426 and $5,144, respectively, was not considered mandatorily redeemable and reclassified to MRCS because the requesting members may revoke their requests, without substantial penalty, throughout the five-year waiting period. Therefore, these requests are not considered sufficiently substantive in nature. However, we consider redemption requests related to mergers, acquisitions or charter terminations, as well as involuntary terminations from membership, to be sufficiently substantive when made and, therefore, the related stock is considered mandatorily redeemable and reclassified to MRCS.

Mandatorily Redeemable Capital Stock.The following table presents the activity in our MRCS.

In accordance with the Final Membership Rule, captive insurance companies that were admitted as FHLBank members on or after September 12, 2014 had their memberships terminated by February 19, 2017. All of their outstanding Class B stock, totaling $3,021 at December 31, 2016, was repurchased on or before February 19, 2017.

The following table presents MRCS by contractual year of redemption. The year of redemption is the later of (i) the final year of the five-year redemption period, or (ii) the first year in which a non-member no longer has an activity-based stock requirement.

⁽¹⁾  Maximum line of credit amount per member is $50,000.

⁽²⁾  Generally for periods up to six months.

⁽³⁾  Generally for periods up to 91 days.

Pledged Collateral.At September 30, 2018 and December 31, 2017, we had pledged cash collateral, at par, of $124,987 and $16,437, respectively, to counterparties and clearing agents. At September 30, 2018 and December 31, 2017, we had not pledged any securities as collateral.

Legal Proceedings. We are subject to legal proceedings arising in the normal course of business. We record an accrual for a loss contingency when it is probable that a loss for which we could be liable has been incurred and the amount can be reasonably estimated. After consultation with legal counsel, management does not anticipate that the ultimate liability, if any, arising out of these proceedings could have a material effect on our financial condition, results of operations or cash flows.

In 2010, we filed a complaint asserting claims against several entities for negligent misrepresentation and violations of state and federal securities law occurring in connection with the sale of private-label RMBS to us. In 2013, 2014 and 2015, we executed confidential settlement agreements with certain defendants in this litigation, pursuant to which we have dismissed all pending claims against, and provided legal releases to, certain entities with respect to all applicable securities at issue in the litigation, in consideration of our receipt of cash payments from or on behalf of those defendants. We had previously dismissed the complaint as to the other named defendants. As a result, all proceedings in the RMBS litigation we filed have been concluded. Cash settlement payments, net of legal fees and litigation expenses, totaled $317 for the three and nine months ended September 30, 2018, respectively, compared to $134 and $312 for the three and nine months ended September 30, 2017, respectively, and were recorded in other income.

Additional discussion of other commitments and contingencies is provided inNote 6 - Advances; Note 7 - Mortgage Loans Held for Portfolio; Note 9 - Derivatives and Hedging Activities; Note 10 - Consolidated Obligations; Note 12 - Capital; and Note 15 - Estimated Fair Values.

⁽¹⁾  The recorded investment in a loan is the UPB of the loan, adjusted for accrued interest, net of any deferred loan fees or costs, unamortized premiums or discounts (which may include the basis adjustment related to any gain or loss on a delivery commitment prior to being funded) and direct charge-offs. The recorded investment is not net of any valuation allowance.

⁽²⁾  Includes loans for which the decision of foreclosure or similar alternative, such as pursuit of deed-in-lieu of foreclosure, has been reported. Loans in process of foreclosure are included in past due categories depending on their delinquency status, but are not necessarily considered to be on non-accrual status.

⁽³⁾  Represents loans 90 days or more past due (including loans in process of foreclosure) expressed as a percentage of the total recorded investment in mortgage loans. The percentage excludes principal and interest amounts previously paid in full by the servicers on conventional loans that are pending resolution of potential loss claims. Our servicers repurchase seriously delinquent government loans, including FHA loans, when certain criteria are met.

⁽⁴⁾  Although our past due scheduled/scheduled MPP loans are classified as loans past due 90 days or more based on the loan's delinquency status, we do not consider these loans to be on non-accrual status.

Impact of MPP Risk Sharing Structure on Allowance for Credit Losses

The following table presents the components of the allowance for loan losses, including the credit enhancement waterfall for MPP.

Components of Allowance	September 30, 2018			December 31, 2017

SMI	(1,309		)	(2,383		)
Total portion recoverable from credit enhancements	(3,223		)	(4,640		)
Allowance for unrecoverable PMI/SMI	30			30
Allowance for MPP loan losses	500			750
Allowance for MPF Program loan losses	100			100
Allowance for loan losses	$	600		$	850

⁽¹⁾  Based on a loss emergence period of 24 months.

⁽²⁾  Amounts recoverable are limited to (i) the estimated losses remaining after borrower's equity and PMI and (ii) the remaining balance in each pool's portion of the LRA. The remainder of the total LRA balance is available to cover any losses not yet incurred and to distribute any excess funds to the PFIs.

[1] The recorded investment in a loan is the UPB of the loan, adjusted for accrued interest, net of any deferred loan fees or costs, unamortized premiums or discounts (which may include the basis adjustment related to any gain or loss on a delivery commitment prior to being funded) and direct charge-offs. The recorded investment is not net of any valuation allowance.

[2] Includes loans for which the decision of foreclosure or similar alternative, such as pursuit of deed-in-lieu of foreclosure, has been reported. Loans in process of foreclosure are included in past due categories depending on their delinquency status, but are not necessarily considered to be on non-accrual status.

[3] Represents loans 90 days or more past due (including loans in process of foreclosure) expressed as a percentage of the total recorded investment in mortgage loans. The percentage excludes principal and interest amounts previously paid in full by the servicers on conventional loans that are pending resolution of potential loss claims. Our servicers repurchase seriously delinquent government loans, including FHA loans, when certain criteria are met.

[4] Although our past due scheduled/scheduled MPP loans are classified as loans past due 90 days or more based on the loan's delinquency status, we do not consider these loans to be on non-accrual status.
