Notes to Financial Statements

(Unaudited, $ amounts in thousands unless otherwise indicated)

Note 1 - Summary of Significant Accounting Policies

Basis of Presentation. The accompanying interim financial statements of the Federal Home Loan Bank of Indianapolis have been prepared in accordance with GAAP for interim financial information and with the instructions provided by the SEC. Accordingly, they do not include all of the information and disclosures required by GAAP for complete financial statements. The interim financial statements presented herein should be read in conjunction with our audited financial statements and notes thereto, which are included in our 2012 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 fiscal year or any other interim period.

Our significant accounting policies and certain other disclosures are set forth in Note 1 - Summary of Significant Accounting Policiesin our 2012 Form 10-K. There have been no material changes to these policies through June 30, 2013.

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

Reclassifications. We have reclassified certain amounts from the prior periods to conform to the current period presentation. These reclassifications had no effect on Net Income, Total Comprehensive Income, Total Assets, Total Capital, or Cash Flows.

Use of Estimates.The preparation of financial statements in accordance with GAAP requires us 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. Actual results could differ significantly from these estimates.

Financial Instruments with Legal Right of Offset.We present certain financial instruments, including derivative instruments and securities purchased under agreements to resell, on a net basis when they have a legal right of offset and all other requirements for netting are met (collectively referred to as the netting requirements). For these financial instruments, we have elected to offset our derivative asset and liability positions, as well as cash collateral received or pledged, when we have met the netting requirements. We did not have any offsetting liabilities related to securities purchased under agreements to resell at June 30, 2013 and December 31, 2012.

The net exposure for these financial instruments can change on a daily basis; therefore, there may be a delay between the time this exposure change is identified and additional collateral is requested, and the time when this collateral is received or pledged. Likewise, there may be a delay for excess collateral to be returned. For derivative instruments that meet the netting requirements, any excess cash collateral received or pledged is recognized as a derivative liability or derivative asset. Additional information regarding these agreements is provided in Note 9 - Derivatives and Hedging Activities. Based on the fair value of the related collateral held, the securities purchased under agreements to resell were fully collateralized for the periods presented.

Note 2 - Recently Adopted and Issued Accounting Guidance

Inclusion of the Fed Funds Effective Swap Rate (or OIS) as a Benchmark Interest Rate for Hedge Accounting Purposes. On July 17, 2013, the FASB amended existing guidance to include the Fed Funds Effective Swap Rate, also referred to as OIS, as a United States benchmark interest rate for hedge accounting purposes. Including OIS as an acceptable United States benchmark interest rate, in addition to United States Treasuries and LIBOR, will provide a more comprehensive spectrum of interest rate resets to use as the designated benchmark interest rate risk component under the hedge accounting guidance. The amendments also remove the restriction on using different benchmark interest rates for similar hedges. The amendments apply to all entities that elect to apply hedge accounting of the benchmark interest rate, and are effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. We are currently in the process of evaluating the potential effects of this guidance on our hedging strategies.

Joint and Several Liability Arrangements. On February 28, 2013, the FASB issued guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date. This guidance requires an entity to measure these obligations as the sum of (i) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (ii) any additional amount the reporting entity expects to pay on behalf of its co-obligors. In addition, this guidance requires an entity to disclose the nature and the amount of the obligation as well as other information about those obligations. This guidance is effective for interim and annual periods beginning on or after December 15, 2013 and should be applied retrospectively to obligations with joint and several liabilities existing at the beginning of an entity's fiscal year of adoption. This guidance will not have any effect on our financial condition, results of operations or cash flows.

Presentation of Comprehensive Income. On February 5, 2013, the FASB issued guidance to improve the transparency of reporting classifications out of AOCI. This guidance does not change the current requirements for reporting net income or comprehensive income in financial statements. However, it does require us to provide information about the amounts reclassified out of AOCI by component. In addition, we are required to present, either on the face of the financial statement where net income is presented or in the notes, significant amounts reclassified out of AOCI. These amounts must be presented based on the respective lines of net income if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, we are required to cross-reference to other required disclosures that provide additional detail about these other amounts. This guidance became effective for interim and annual periods beginning on January 1, 2013 and was applied prospectively. The adoption of this guidance resulted in additional financial statement disclosures, but did not have any effect on our financial condition, results of operations or cash flows. See Note 14 - Accumulated Other Comprehensive Income (Loss)for additional disclosures required by this guidance.

Disclosures about Offsetting Assets and Liabilities.On December 16, 2011, the FASB issued common disclosure requirements intended to help investors and other financial statement users better assess the effect or potential effect of offsetting arrangements on a company's financial position. This guidance was amended on January 31, 2013 to clarify that its scope includes only certain financial instruments that are either offset on the statement of condition or are subject to an enforceable master netting arrangement or similar agreement. This guidance requires us to disclose both gross and net information about derivative, repurchase and security lending instruments that meet this criteria. This guidance, as amended, became effective for interim and annual periods beginning on January 1, 2013, and was applied retrospectively for all comparative periods presented. The adoption of this guidance resulted in expanded interim and annual financial statement disclosures, but did not have any effect on our financial condition, results of operations or cash flows. See Note 9 - Derivatives and Hedging Activities for additional disclosures required by this guidance.

Advisory Bulletin 2012-02.On April 9, 2012, the Finance Agency issued Advisory Bulletin 2012-02, Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention ("AB-2012-02"). The guidance establishes a standard and uniform methodology for adversely classifying certain assets other than investment securities, and prescribes the timing of asset charge-offs based on these classifications. Such classification methodology and accounting treatment differ from our current methodology and accounting policy. AB-2012-02 states that it was effective upon issuance. However, the Finance Agency issued additional guidance that extended the effective date for classification purposes to January 1, 2014; and the effective date for financial reporting purposes to January 1, 2015. We are in the process of implementing this guidance. While we are evaluating the effect of this guidance on our financial condition, results of operations and cash flows, we do not expect it to be material.

Realized Gains and Losses. The following table presents the proceeds, previously recognized OTTI credit losses including accretion, and gross realized gains and losses related to the sale of six OTTI AFS securities, only one of which was in an unrealized loss position. In the first quarter of 2013, we recorded an OTTI credit charge for this security, representing the entire difference between our amortized cost basis and its estimated fair value, which resulted in no gross realized losses related to the sale. We compute gains and losses on sales of investment securities using the specific identification method.

Note 5 - Other-Than-Temporary Impairment Analysis

OTTI Evaluation Process and Results - Private-label RMBS and ABS. We evaluate our individual AFS and HTM securities that have been previously OTTI or are in an unrealized loss position for OTTI on a quarterly basis. As part of our evaluation, we consider whether we intend to sell each security and whether it is more likely than not that we will be required to sell the security before its anticipated recovery.

If either of these conditions is met, we recognize an OTTI loss in earnings equal to the entire difference between the debt security's amortized cost and its estimated fair value as of the Statement of Condition date. For the six months ended June 30, 2013, we recorded an OTTI credit charge of $1,924, representing the entire difference between our amortized cost basis and its estimated fair value, on one security for which we changed our previous intention to hold until recovery of its amortized cost. We did not have any such change in intent during the three months ended June 30,2013 or the three and six months ended June 30, 2012.

For those securities that meet neither of these conditions, we perform a cash flow analysis to determine whether we expect to recover the entire amortized cost of each security as described in Note 6 - Other-Than-Temporary Impairment Analysis of our 2012 Form 10-K. As a result of our analysis, we recognized additional OTTI credit losses of $0 and $292 for the three months ended June 30,2013 and 2012, respectively, and $0 and $3,580 during the six months ended June 30, 2013 and 2012, respectively. We determined that the unrealized losses on the remaining private-label RMBS and ABS were temporary as we expect to recover the entire amortized cost.

The following table presents a rollforward of the amounts related to credit losses recognized in earnings. The rollforward excludes accretion of credit losses for securities that have not experienced a significant increase in cash flows.

	Three Months Ended						Six Months Ended

The following table presents the June 30, 2013 classification and balances of OTTI securities impaired prior to June 30, 2013 (i.e., life to date) but not necessarily as of June 30, 2013. Securities are classified based on the originator's classification at the time of origination or based on the classification by the NRSROs upon issuance. Because there is no universally accepted definition of prime, Alt-A or subprime underwriting standards, such classifications are subjective.

OTTI Evaluation Process and Results - All Other AFS and HTM Securities.

Other U.S. and GSE Obligations and TVA Debentures. For other U.S. obligations, GSE obligations, and TVA debentures, we determined that 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 based on current expectations. As a result, we have determined that, as of June 30, 2013, all of the gross unrealized losses are temporary.

Note 6 - Advances

We had Advances outstanding, as presented below by year of contractual maturity, with interest rates ranging from 0% to 8.34%.

Unamortized swap termination fees associated with modified Advances	120,026				171,298
Total Advances	$	19,100,599			$	18,129,458

We offer our members certain Advances that provide them the right, at predetermined future dates, to prepay the Advance prior to maturity without incurring prepayment or termination fees. In exchange for receiving this right, a member typically pays a higher fixed rate for the Advance relative to a non-callable, fixed-rate Advance with an equivalent maturity or pays a higher spread on an adjustable rate Advance relative to a non-callable variable rate Advance with an equivalent maturity. If the call option is exercised, replacement funding may be available. Borrowers typically exercise their call options for fixed-rate Advances when interest rates decline or for adjustable-rate Advances when spreads change. At June 30, 2013 and December 31, 2012, we had such Advances outstanding of $3.5 billion and $3.7 billion, respectively. All other Advances may only be prepaid by paying a fee (prepayment fee) that is sufficient to make us financially indifferent to the prepayment of the Advance.

We offer putable and convertible Advances. Under the terms of a putable Advance, we retain the right to extinguish or put the fixed-rate Advance to the member on predetermined future dates, and offer, subject to certain conditions, replacement funding at prevailing market rates. At June 30, 2013 and December 31, 2012, we had putable Advances outstanding totaling $257,000 and $351,500, respectively. Under the terms of a convertible Advance, we may convert an Advance from one interest payment term structure to another. We had no convertible Advances outstanding at June 30, 2013 or December 31, 2012.

Prepayment Fees.When a borrower prepays an Advance, future income will be lower if the principal portion of the prepaid Advance is reinvested in lower-yielding assets that continue to be funded by higher-costing debt. To protect against this risk, we generally charge a prepayment fee. Advance prepayment fees, excluding any associated hedging basis adjustments, at the time of the prepayment were $25,193 and $30,841 for the three and six months ended June 30, 2013 compared to $6,778 and $7,670 for the three and six months ended June 30, 2012, respectively.

In cases in which we fund a new Advance concurrent with or within a short period of time before or after the prepayment of an existing Advance and the Advance meets the accounting criteria to qualify as a modification of the prepaid Advance, any prepayment fee, net of hedging basis adjustments, is deferred, recorded in the basis of the modified Advance, and amortized using a level-yield methodology over the life of the modified Advance, or as an adjustment to the interest coupon accrual of the modified Advance. For the three and six months ended June 30, 2013, we deferred $4,704 and $11,935, respectively, of these gross Advance prepayment fees, compared to $6,092 and $26,891, respectively, for the three and six months ended June 30, 2012.

Credit Risk Exposure and Security Terms. At June 30, 2013 and December 31, 2012, we had a total of $8.5 billion and $8.4 billion, respectively, of Advances outstanding, at par, to single borrowers with balances that were greater than or equal to $1.0 billion. These Advances, representing 46% and 48%, respectively, of total Advances at par outstanding on those dates, were made to four and five borrowers, respectively. At June 30, 2013 and December 31, 2012, we held $15.5 billion and $17.9 billion, respectively, of UPB of collateral to cover the Advances to these borrowers.

Note 8 - Allowance for Credit Losses

We have established an allowance methodology for each of our portfolio segments: credit products (Advances, letters of credit, and other extensions of credit to members); term securities purchased under agreements to resell; term federal funds sold; government-guaranteed or insured Mortgage Loans Held for Portfolio; and conventional Mortgage Loans Held for Portfolio. A description of the allowance methodologies related to our portfolio segments is disclosed in Note 9 - Allowance for Credit Losses in our 2012 Form 10-K.

Credit Products. Using a risk-based approach, we consider the amount and quality of the collateral pledged and the borrower's financial condition to be indicators of credit quality on the borrower's credit products. At June 30, 2013 and December 31, 2012, we had rights to collateral on a member-by-member basis with an estimated value in excess of our outstanding extensions of credit.

At June 30, 2013 and December 31, 2012, we did not have any credit products that were past due, on non-accrual status, or considered impaired.

Based upon the collateral held as security, our credit extension and collateral policies, our credit analysis and the repayment history on credit products, we have not recorded any allowance for credit losses on credit products. At June 30, 2013 and December 31, 2012, no liability to reflect an allowance for credit losses for off-balance sheet credit exposures was recorded. For additional information about off-balance sheet credit exposure, see Note 17 - Commitments and Contingencies.

MortgageLoans.

Credit Enhancements.

MPP Credit Enhancements. Our allowance for loan losses considers the credit enhancements associated with conventional mortgage loans under the MPP, which includes the original program and MPP Advantage. Any estimated losses that would be recovered from the credit enhancements are not reserved for as part of our allowance for loan losses. However, as part of the estimate of the recoverable credit enhancements, we evaluate the recovery and collectability related to our PMI/SMI policies. As a result of our evaluation, we reduced our estimates of recovery associated with the expected amount of our claims for all providers of these policies and established an allowance for unrecoverable PMI/SMI at June 30, 2013 and December 31, 2012 of $1,941 and $6,067, respectively, as a component of the allowance for MPP loan losses. This decrease in the allowance for unrecoverable PMI/SMI substantially comprised the reduction in our allowance for credit losses from December 31, 2012 to June 30, 2013.

The credit enhancements are applied to the estimated losses after any remaining borrower's equity in the following order: any applicable PMI up to coverage limits, any available funds remaining in the LRA up to each master commitment contract's allocated share, and any SMI coverage (not applicable to the MPP Advantage) up to the policy limits. Since we would bear any remaining loss, an estimate of the remaining loss is included in our allowance for loan losses.

The following table presents the impact of credit enhancements on the allowance:

MPP Credit Waterfall	June 30, 2013			December 31, 2012
Estimated losses remaining after borrower's equity, before credit enhancements	$	44,258		$	51,465
Portion of estimated losses recoverable from PMI	(5,543		)	(6,494		)
Portion of estimated losses recoverable from LRA	(6,846		)	(7,750		)

Distributions	(541		)	(523		)
Balance of LRA, end of period	$	40,091		$	26,335

MPF Credit Enhancements. Our gross and net CE Fees paid to PFIs under the MPF program were $71 and $0 for the three months ended June 30,2013 and 2012, respectively, and $117 and $0 for the six months ended June 30, 2013 and 2012, respectively. We have had no performance-based CE Fees withheld or recovered from PFIs in 2013 or 2012.

If losses occur in a master commitment, these losses will either be: (i) recovered through the withholding of future performance-based CE Fees from the PFI or (ii) absorbed by us in the FLA. As of June 30, 2013 and December 31, 2012, our exposure under the FLA was $2,784 and $1,157, respectively, with CE Obligations available to cover losses in excess of the FLA totaling $21,320 and $8,607, respectively. Any estimated losses that would be absorbed by the CE Obligation are not reserved for as part of our allowance for loan losses. Accordingly, the calculated allowance was reduced by $151 and $67 as of June 30, 2013 and December 31, 2012, respectively, for the amount in excess of the FLA to be covered by PFIs’ CE Obligations. The resulting allowance for MPF loan losses at June 30, 2013 and December 31, 2012 was $500 and $150, respectively.

Allowance for Loan Losses on Mortgage Loans. The tables below present a rollforward of our allowance for loan losses on mortgage loans, the allowance for loan losses by impairment methodology, and the recorded investment in mortgage loans by impairment methodology. The recorded investment in a loan is the UPB of the loan, adjusted for accrued interest, net of 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 write-downs. The recorded investment is not net of any valuation allowance.

⁽¹⁾  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.

⁽²⁾  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 amounts that were previously paid in full by the servicers on conventional loans that are pending resolution of potential loss claims. Many FHA loans are repurchased by the servicers when they reach 90 days or more delinquent status, similar to the rules for servicers of Ginnie Mae MBS, resulting in the lower serious delinquency rate for FHA loans.

⁽³⁾  Although our past due scheduled/scheduled MPP loans are classified as loans past due 90 days or more based on the mortgagor's payment status, we do not consider these loans to be non-accrual.

Troubled Debt Restructurings. There were no MPF troubled debt restructurings at June 30, 2013 or December 31, 2012.

The table below presents the recorded investment of the performing and non-performing MPP troubled debt restructurings.

During the three and six months ended June 30, 2013 and 2012, certain conventional MPP loans classified as troubled debt restructurings within the previous 12 months experienced a payment default. A borrower is considered to have defaulted on a troubled debt restructuring if the borrower's contractually due principal or interest is 60 days or more past due at any time during the period presented. The recorded investment of certain conventional MPP loans classified as troubled debt restructurings within the previous 12 months that experienced a payment default was $420 and $1,041 for the three and six months ended June 30, 2013, respectively, compared to $2,157 and $2,829 for the three and six months ended June 30, 2012, respectively. For purposes of this disclosure, only the initial default was included; however, a loan can experience another payment default in a subsequent period.

Managing Credit Risk on Derivatives. We are subject to credit risk due to the risk of nonperformance by counterparties to our derivative agreements. We manage counterparty credit risk through credit analysis, collateral requirements and adherence to the requirements set forth in our policies and Finance Agency regulations.

For bilateral derivatives, the degree of credit risk depends on the extent to which master netting arrangements are included in such contracts to mitigate the risk. We require collateral agreements with collateral delivery thresholds on the majority of our bilateral derivatives. Additionally, collateral related to derivatives with member institutions includes collateral assigned to us, as evidenced by a written security agreement and held by the member institution for our benefit.

For cleared derivatives, the Clearinghouse is our counterparty and, therefore, our credit risk exposure is with a central counterparty rather than individual counterparties. Collateral is required to be posted daily for changes in the value of cleared derivatives to mitigate each counterparty's credit risk. The additional requirement that we post initial and variation margin through the clearing member, for the benefit of the Clearinghouse, exposes us to institutional credit risk in the event that the clearing member or Clearinghouse fails to meet its obligations.

See Note 16 - Estimated Fair Values for discussion regarding our fair value methodology for derivative assets and liabilities, including an evaluation of the potential for the estimated fair value of these instruments to be affected by counterparty credit risk.

25

Notes to Financial Statements, continued

(Unaudited, $ amounts in thousands unless otherwise indicated)

We have credit support agreements for our bilateral derivatives 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 bilateral derivative instruments in net liability positions. The aggregate estimated fair value of all bilateral 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 June 30, 2013 was $605,962 for which we have posted collateral, including accrued interest, with an estimated fair value of $410,381 in the normal course of business. In addition, we held other derivative instruments in a net liability position of $2,261 that are not subject to credit support agreements containing credit-risk related contingent features. If our credit rating had been lowered by an NRSRO (from an S&P equivalent of AA+ to AA), we could have been required to deliver up to an additional $52,852 of collateral (at estimated fair value) to our derivative counterparties at June 30, 2013.

Note 11 - Consolidated Obligations

As provided by the Bank Act and applicable regulations, Consolidated Obligations are backed only by the financial resources of all 12 FHLBanks. Although we are primarily liable for our portion of Consolidated Obligations (i.e., those issued on our behalf), we are also jointly and severally liable with the other 11 FHLBanks for the payment of the principal and interest on all Consolidated Obligations of each of the FHLBanks. No FHLBank has ever been asked or required to repay the principal or interest on any Consolidated Obligation on behalf of another FHLBank, and we do not believe that it is probable that we will be asked to do so. The par values of the 12 FHLBanks' outstanding Consolidated Obligations, including Consolidated Obligations held by other FHLBanks, totaled $704.5 billion and $687.9 billion at June 30, 2013 and December 31, 2012, respectively.

Mandatorily Redeemable Capital Stock.At June 30, 2013 and December 31, 2012, we had $255,720 and $450,716, respectively, in capital stock subject to mandatory redemption, which is classified as a liability in the Statement of Condition.

The following table presents the activity in MRCS:

	Three Months Ended June 30,						Six Months Ended June 30,

There were 17 and 27 former members holding MRCS at June 30, 2013 and December 31, 2012, respectively, which include zero and eight institutions, respectively, that were members at the time of their acquisition by the FDIC in its capacity as receiver. During the three months ended June 30, 2013, we repurchased MRCS of $355 pursuant to our statutory and contractual lien on excess capital stock owned by a former member in order to enforce our contractual rights under our MPP and our Advances, Pledge and Security Agreement regarding mortgage loans sold to us. During the six months ended June 30, 2013, we repurchased $250,000 par value of excess stock held as of December 31, 2012 by shareholders that are former members (or their successors-in-interest). We redeemed an additional $40,574 of excess stock held by members or former members because the stock had reached the end of its five-year redemption period.

The following table presents the amount of MRCS by contractual year of redemption. The year of redemption in the table is the later of the end of the five-year redemption period, or the maturity date of the activity to which the stock is related, if the stock represents the activity-based stock purchase requirement of a non-member (a former member that withdrew from membership, merged into a non-member or was otherwise acquired by a non-member).

Excess Capital Stock. Excess capital stock is defined as the amount of stock held by a member or former member in excess of that institution's minimum stock requirement. Finance Agency rules limit the ability of an FHLBank to create member excess stock under certain circumstances, including if excess stock exceeds 1% of Total Assets or if the issuance of excess stock would cause excess stock to exceed 1% of Total Assets. Our excess stock totaled $691,578 at June 30, 2013, which equaled approximately 1.7% of our Total Assets. Therefore, we are currently not permitted to issue new excess stock to members or distribute stock dividends.

Note 16 - Estimated Fair Values

We review the fair value hierarchy classifications on a quarterly basis. Changes in the observability of the inputs may result in a reclassification of certain assets or liabilities. Such reclassifications are reported as transfers in/out at estimated fair value as of the beginning of the quarter in which the changes occur. As described below, we reclassified six AFS securities from Level 3 to Level 2 during the six months ended June 30, 2013. There were no such reclassifications during the three months ended June 30, 2013 and the three and six months ended June 30, 2012.

The following tables present the carrying value and estimated fair value of each of our financial assets and liabilities. The total of the estimated fair values does not represent an estimate of our overall market value as a going concern, which would take into account future business opportunities and the net profitability of assets and liabilities among other considerations.

Summary of Valuation Techniques and Significant Inputs. A description of the valuation techniques, significant inputs, and levels of fair value hierarchy is disclosed in Note 19 - Estimated Fair Valuesinour 2012 Form 10-K, and no changes have been made in the current year, except as disclosed below.

Derivative Assets/Liabilities. The estimated fair values of our derivatives are adjusted for counterparty nonperformance risk, particularly credit risk, as appropriate. Our nonperformance risk adjustment is computed using observable credit default swap spreads and estimated probability default rates applied to our exposure after taking into consideration collateral held or placed. The nonperformance risk adjustment is not material to our derivative valuations or financial statements.

Level 3 Disclosures for All Assets and Liabilities that are Measured at Fair Value on a Recurring Basis. The table below presents a rollforward of our AFS private-label RMBS measured at estimated fair value on a recurring basis using Level 3 significant inputs. The estimated fair values for the private-label RMBS were valued using a pricing source, such as a dealer quote or comparable security price, for which the significant unobservable inputs used to determine the price were not reasonably available.

We classified the six securities we sold on April 4, 2013 as Level 2 within the fair value hierarchy as of March 31, 2013 because the estimated fair values were derived from and corroborated by the sales prices in actual market transactions. The total fair value of these six securities that we transferred from Level 3 to Level 2 was $124,179 as of January 1, 2013, the beginning of the quarter in which the transfer occurred.

Note 18 - Transactions with Related Parties

For financial reporting purposes, we define related parties as those members, and former members and their affiliates, with capital stock outstanding in excess of 10% of our total outstanding Capital Stock and MRCS. Transactions with such related parties are entered into in the normal course of business and are subject to the same eligibility and credit criteria, as well as the same terms and conditions, as other similar transactions. In addition, under our Capital Plan, our members (including directors' financial institutions) have an activity-based Capital Stock requirement pursuant to which they purchase additional Capital Stock in specified amounts (generally expressed as a percentage of the transaction amount) when they obtain Advances from us or in certain cases sell mortgage loans to us.

Beginning in July 2012,we pay an MPF Provider fee to the FHLBank of Chicago for our participation in the MPF program. This fee is recorded in Other Expenses. For the three and six months ended June 30, 2013, we paid $54 and $92, respectively, in MPF Provider fees to the FHLBank of Chicago.

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

Presentation 

This Management's Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our 2012 Form 10-K and the financial statements and related footnotes contained in this Form 10-Q in Item 1. Financial Statements.

As used in this Form 10-Q, unless the context otherwise requires, the terms "we," "us," "our," and the "Bank" refer to the Federal Home Loan Bank of Indianapolis or its management. We use certain acronyms and terms throughout this Form 10-Q that are defined in the Glossary of Terms located in Item 1. Financial Statements.

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

Special Note Regarding Forward-Looking Statements

Statements in this Form 10-Q, including statements describing our objectives, projections, estimates or future predictions, may be "forward-looking statements." These statements may use forward-looking terminology, such as "anticipates," "believes," "could," "estimates," "may," "should," "expects," "will," or their negatives or other variations on these terms. We caution that, by their nature, forward-looking statements involve risk or uncertainty and that actual results either could differ materially from those expressed or implied in these forward-looking statements or could affect the extent to which a particular objective, projection, estimate, or prediction is realized. These forward-looking statements involve risks and uncertainties including, but not limited to, the following:

• economic and market conditions, including the timing and volume of market activity, inflation or deflation, changes in the value of global currencies, and changes in the financial condition of market participants;

• volatility of market prices, interest rates, and indices or other factors, resulting from the effects of, and changes in, various monetary or fiscal policies and regulations, including those determined by the Federal Reserve Board and the FDIC, or a decline in liquidity in the financial markets that could affect the value of investments (including OTTI of private-label RMBS) or collateral we hold as security for the obligations of our members and counterparties;

• demand for our Advances and purchases of mortgage loans under our MPP or participation interests in mortgage loans purchased from other FHLBanks under the MPF program resulting from:

◦ changes in our members' deposit flows and credit demands;

◦ membership changes, including, but not limited to, mergers, acquisitions and consolidations of charters;

◦ changes in the general level of housing activity in the United States, the level of refinancing activity and consumer product preferences; and

◦ competitive forces, including, without limitation, other sources of funding available to our members;

• changes in mortgage asset prepayment patterns, delinquency rates and housing values;

Executive Summary

Overview. We are a regional wholesale bank that makes Advances; purchases whole mortgages from our member financial institutions; purchases participation interests in mortgage loans from other FHLBanks; purchases other investments; and provides other financial services to our member financial institutions. Our member financial institutions may consist of federally-insured depository institutions (including commercial banks, thrifts, and credit unions), insurance companies and community development financial institutions. All member financial institutions are required to purchase shares of our Class B Capital Stock as a condition of membership. 

Our public policy mission is to facilitate and expand the availability of financing for housing and community development. We seek to achieve our mission by providing products and services to our members in a safe, sound, and profitable manner, and by generating a competitive return on their capital investment. See Item 1. Business - Background Information in our 2012 Form 10-K for more information.

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 12 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 interest-rate spread between the interest rate earned on our assets and the interest rate paid on our share of the Consolidated Obligations. We use funding and hedging strategies to manage the related interest-rate risk.

Economic Conditions. According to a report issued by S&P on June 27, 2013, despite signs that the recession is easing for the Eurozone as a whole, a meaningful recovery still appears some way off.Europe's financial markets and economy remain under significant stress, which is likely to continue to negatively affect the global economy.

There have been signs of improvement in the outlook for the United States economy. The temporary suspension of the United States debt ceiling limit agreed to in February 2013 by Congress expired on May 18, 2013. The United States Treasury began employing measures to allow the government to fulfill its obligations until after Labor Day. These measures, along with some sequestration of spending and higher tax revenues, have reduced the government's projected 2013 deficit.

On June 10, 2013, S&P affirmed the AA+ long-term senior debt rating of the FHLBank System and revised its outlook on our Consolidated Obligations from negative to stable. S&P also affirmed the A-1+ short-term debt ratings of the FHLBank System. The outlook on the FHLBank System was revised to stable, reflecting the stable outlook of the United States government. In the application of S&P's Government Related Entities criteria, the ratings of the FHLBank System are constrained by the long-term sovereign rating of the United States government. On July 18, 2013, Moody's affirmed the Aaa long-term senior debt rating of the FHLBank System and revised its outlook on our Consolidated Obligations from negative to stable. Moody's also affirmed the Prime-1 short-term debt ratings of the FHLBank System. The outlook on the FHLBank System was revised to stable as a result of the update of the outlook on the United States government to stable.

The Bureau of Labor Statistics reported that Michigan's preliminary unemployment rate equaled 8.7% for June 2013, while Indiana's preliminary rate was 8.4%, compared to the national rate of 7.6%. According to information provided by LPS Applied Analytics for May, Indiana had a non-current mortgage rate (loans past due 30 days or more) of 10.3%, and Michigan had a non-current mortgage rate of 7.6%, compared to the national rate of 9.1%.

In its May 2013 forecast, the Center for Econometric Research at Indiana University predicts a pullback in both employment and personal income growth for the Indiana economy over 2013 before improving in 2014. The May 2013 forecast published by the Research Seminar in Quantitative Economics at the University of Michigan predicts a moderately paced but sustained recovery in Michigan from now through 2014. University of Michigan economists expect continued job growth in Michigan over the next two years, with some pickup in 2013 compared to 2012. However, on July 18, 2013, the city of Detroit, one of the largest cities in our district, declared bankruptcy. See Item 1A. Risk Factors for more information.

The Capital Markets.Although the capital markets were fairly stable during the first quarter of 2013, volatility and interest rates increased significantly during the latter half of the second quarter of 2013 due to the continuing Eurozone recessions and uncertainty caused by conditions in the United States economy. During the second quarter of 2013, the FOMC reported that economic activity has been expanding at a moderate pace. Market participants focused on the possibility of a near-term reduction in Federal Reserve support in the form of United States Treasury security and MBS purchases as economic indicators pointed to an improving economy.

To support a stronger economic recovery and to help ensure that inflation, over time, is at the rate most consistent with its dual mandate, the FOMC agreed in June to continue purchasing additional agency MBS at a pace of $40 billion per month and longer-term United States Treasury securities at a pace of $45 billion per month.

Taxable money market funds purchase a significant portion of the Discount Notes and short maturity CO Bonds issued by the FHLBanks. Potential changes to money market funds, one of the FHLBank System's most important investor bases, could affect our debt. On June 19, 2013, the SEC proposed reforms to Rule 2A-7, which governs money funds. The proposal, which is open for public comment, contains two key provisions that impact prime institutional money funds: (i) floating net asset value, and (ii) the possibility of imposing fees and redemption gates, which would require a waiting period prior to the holder of funds being able to withdraw funds in total. These provisions could be adopted alone or in combination. As government money market funds are exempt from implementing these changes, these potential changes are not expected to have negative consequences for FHLBank debt demand. However, the potential exists for refinement of the proposed changes once the comment period ends.

The increase in Net Income for the second quarter of 2013 compared to the same period in 2012 was primarily due to unrealized gains on hedging activities and a net realized gain on the sale of private-label MBS.

The increase in Net Income for the six months ended June 30, 2013 compared to the same period in 2012 was primarily due to a net realized gain on the sale of private-label MBS and unrealized gains on hedging activities.

The decrease in Total Other Comprehensive Income (Loss) for the second quarter of 2013, compared to the same period in 2012, was primarily due to decreases in the fair value of AFS securities and a reclassification of net realized gains from sale of securities to Other Income.

The decrease in Total Other Comprehensive Income (Loss) for the six months ended June 30, 2013 compared to the same period in 2012 was primarily due to the reclassification of the net realized gains from the sale of securities to Other Income.

⁽¹⁾  Includes HTM Securities, AFS Securities, Interest-Bearing Deposits, Securities Purchased Under Agreements to Resell, and Federal Funds Sold.

⁽²⁾  Other Assets includes Cash and Due From Banks of $29.6 million and $105.5 million at June 30, 2013 and December 31, 2012, respectively.

⁽³⁾  Total Regulatory Capital is Total Capital plus MRCS less AOCI.

The decrease in Total Assets at June 30, 2013 compared to December 31, 2012 was primarily due to a decrease in Investments, partially offset by increases in Advances and Mortgage Loans Held for Portfolio. The net decrease in Investments was mainly due to a managed reduction in short-term investments, which were maintained at a higher level at December 31, 2012 due to the economic and political uncertainty at that time. The increase in Advances outstanding was attributable to higher Advances to our insurance company members, partially offset by lower Advances to our depository members. The increase in Mortgage Loans Held for Portfolio was attributable to purchases of mortgage loans under our MPP Advantage program and participation interests purchased from the FHLBank of Topeka under our MPF program. The net decrease in Consolidated Obligations was attributable to our lower funding needs.

The increase in Total Capital consisted of net increases in Capital Stock and Retained Earnings and a favorable change in AOCI, primarily due to an increase in the fair value of OTTI AFS securities.

The favorable changes in Other Income (Loss) for the three and six months ended June 30, 2013 compared to the same periods in 2012 were primarily due to net realized gains from the sale of AFS securities and Net Gains on Derivatives and Hedging Activities.

Results of OTTI Evaluation Process. The favorable change in OTTI credit losses for the six months ended June 30, 2013, compared to the same period in 2012, was due to a relative improvement in the projected performance of the underlying collateral. For additional detail, see Notes to Financial Statements - Note 5 - Other-Than-Temporary Impairment Analysis.

Net Realized Gains from Sale of Available-for-Sale Securities. On April 4, 2013 we sold six AFS securities due to improved market conditions and changes affecting our risk tolerances.

Net Gains (Losses) on Derivatives and Hedging Activities. The favorable change in Net Gains (Losses) on Derivatives and Hedging Activities for thethree and six months ended June 30, 2013 was primarily due to fair value hedge ineffectiveness in our qualifying hedging relationships. For additional detail, see Notes to Financial Statements - Note 9 - Derivatives and Hedging Activities.

In 2013, we discontinued hedge accounting for 19 derivatives with a total notional amount of $2.0 billion, substantially due to ineffectiveness resulting from the use of the OIS curve to determine the fair value of our derivatives as of December 31, 2012. As a result, interest expense for these derivatives for the three and six months ended June 30, 2013 of $1.0 million and $4.3 million, respectively, was recorded in Other Income (Loss) instead of Net Interest Income. In addition, when hedge accounting is discontinued, we cease adjusting the hedged item's basis for changes in fair value and begin amortizing/accreting the frozen basis adjustment using the level-yield method. This amortization/accretion is included in Net Interest Income. As a result, the related amortization of the frozen basis adjustments for the three and six months ended June 30, 2013 of $2.0 million and $5.3 million, respectively, was recorded as a reduction to Net Interest Income. The overall impact of the discontinuance of hedge accounting on Net Income for the three and six months ended June 30, 2013 was favorable, but not significant.

We continue to carry these derivatives at their estimated fair values and recognize the net interest settlements and changes in the fair value in Other Income (Loss) with no offsetting fair value adjustments for the hedged items. In addition, the OIS curve is also used to determine the estimated fair value of our derivatives in qualifying hedging relationships while the LIBOR curve is used to determine the estimated fair value of our hedged items. For these reasons, our reported earnings remain subject to variability. However, in general, we hold derivatives and associated hedged items to the maturity, call, or put date. Therefore, nearly all of the cumulative net gains and losses for these financial instruments will generally reverse over the remaining contractual terms of the hedged items.

There were no material changes in Other Expenses for the three or six months ended June 30, 2013 compared to the same periods in 2012.

On June 27, 2013, Milton Miller, our former President - CEO, informed our Board of Directors of his decision to retire effective July 1, 2013. Mr. Miller received a lump sum distribution from our Supplemental Executive Retirement Plans totaling $10.3 million on July 12, 2013. As a result of this distribution, we accelerated $5.1 million of amortization of previously unrecognized pension benefits from AOCI into Compensation and Benefits expense in the third quarter of 2013. If any one of the remaining participants in our Supplemental Executive Retirement Plans were to terminate service and elect a lump sum payment, the acceleration of amortization of previously unrecognized pension benefits for that participant would not have a material impact on the financial statements.

Business Segments

Our products and services are grouped within two business segments:Traditional and Mortgage Loans.

The Traditional business segment includes credit services (including Advances, letters of credit, and lines of credit), investments (including Federal Funds Sold, Securities Purchased Under Agreements to Resell, AFS securities, and HTM securities) and correspondent services and deposits.

The following table presents our financial performance for the Traditional business segment ($ amounts in millions):  

	Three Months Ended					Six Months Ended
	June 30,					June 30,
Traditional Business Segment	2013		2012			2013		2012
Net Interest Income	$	40	$	43		$	78	$	83

Income Before Assessments	59		27			78		53
Affordable Housing Program Assessments	6		3			8		6
Net Income	$	53	$	24		$	70	$	47

The increase in Net Income for the Traditional business segment for the three and six months ended June 30, 2013 compared to the same periods in 2012 was primarily due to a favorable change in Other Income (Loss), primarily due to unrealized gains on hedging activities and a net realized gain on the sale of private-label MBS, partially offset by a decrease in Net Interest Income.

The Mortgage Loans business segment includes (i) mortgage loans purchased from our members through our MPP and (ii) participation interests purchased from the FHLBank of Topeka in mortgage loans originated by its members under the MPF program.

51

The following table presents our financial performance for the Mortgage Loans business segment ($ amounts in millions): 

	Three Months Ended					Six Months Ended
	June 30,					June 30,
Mortgage Loans Business Segment	2013		2012			2013			2012

Net Income	$	17	$	10		$	39		$	28

The increase in Net Income for the Mortgage Loans business segment for the three and six months ended June 30, 2013 compared to the same period in 2012 was primarily due to higher spreads on and an increase in Mortgage Loans Held for Portfolio, and the decrease in the Provision for (Reversal of) Credit Losses.

Analysis of Financial Condition

Total Assets. The table below presents the carrying value of our major asset categories as a percentage of combined Total Assets ($ amounts in millions).

	June 30, 2013				December 31, 2012
Major Asset Categories	Carrying Value		% of Total		Carrying Value		% of Total
Advances	$	19,101	48	%	$	18,130	44	%
Mortgage Loans Held for Portfolio, net	6,167		15	%	6,001		15	%
Federal Funds Sold and Securities Purchased Under Agreements to Resell	3,507		9	%	5,360		13	%
Investment Securities (1)	10,960		27	%	11,485		27	%
Other Assets (2)	180		1	%	252		1	%
Total Assets	$	39,915	100	%	$	41,228	100	%

⁽¹⁾    Investment Securities includes AFS and HTM securities.

⁽²⁾  For purposes of this table, Other Assets includes Cash and Due From Banks, Interest-Bearing Deposits, Accrued Interest Receivable, Premises, Software and Equipment, net, Derivative Assets and Other Assets.

Total Assets were $39.9 billion as of June 30, 2013, a decrease of 3% compared to December 31, 2012. This decrease of $1.3 billion was primarily due to decreases in short-term investments totaling $1.9 billion and investment securities totaling $0.5 billion, partially offset by increases in Advances totaling $1.0 billion and in Mortgage Loans Held for Portfolio totaling $0.2 billion. As a result, the mix of our assets changed, with Advances increasing to 48% of our Total Assets and short-term investments decreasing to 9% of our Total Assets.

Advances.Advances totaled $19.1 billion at June 30, 2013, an increase of 5% compared to December 31, 2012. This increase was primarily due to a 21% increase in the par value of Advances to insurance company members, which totaled $10.4 billion at June 30, 2013, partially offset by a 6% reduction in the par value of Advances to all depository borrowers (including former members), resulting from repayments and their reduced need for funding in the current economic environment. In general, Advances fluctuate in accordance with our members' funding needs, which are driven by their deposit levels, mortgage pipelines, investment opportunities, available collateral, other balance sheet strategies, and the cost of alternative funding opportunities.

52

Mortgage Loans Held for Portfolio.We purchase mortgage loans from our members to support our housing mission, provide an additional source of liquidity to our members and diversify our investments. 

A breakdown of Mortgage Loans Held for Portfolio by primary product type is presented below ($ amounts in millions):

	June 30, 2013				December 31, 2012
Mortgage Loans Held for Portfolio	UPB		% of Total		UPB		% of Total
MPP Original	$	3,494	57	%	$	4,111	69	%
MPP Advantage	2,103		35	%	1,585		27	%
Total MPP	5,597		92	%	5,696		96	%
MPF	472		8	%	230		4	%
Total UPB	$	6,069	100	%	$	5,926	100	%

The increase in Mortgage Loans Held for Portfolio was attributable to purchases of mortgage loans under our MPP Advantage program and participation interests purchased from the FHLBank of Topeka under our MPF program. In general, the volume of mortgage loans purchased is affected by several factors, including interest rates, competition, the general level of housing activity in the United States, the level of refinancing activity and consumer product preferences.

We have established and maintain an allowance for loan losses based on our best estimate of probable losses over the loss emergence period. Our estimate of MPP losses remaining after borrower's equity was $44.3 million at June 30, 2013 and $51.5 million at December 31, 2012. The decrease from December 31, 2012 to June 30, 2013 was primarily the result of an improvement in the underlying weighted-average collateral recovery rate and a significant reduction in the number of mortgage loans that are seriously past due.

After consideration of the portion recoverable under the associated credit enhancements, the allowance for MPP loan losses was $5.0 million at June 30, 2013 and $9.9 million at December 31, 2012. The decrease in our allowance from December 31, 2012 to June 30, 2013 was primarily due to an increase in the estimated amounts recoverable from our PMI and SMI providers. See Notes to Financial Statements - Note 8 - Allowance for Credit Losses, Critical Accounting Policies and Estimates, and Risk Management - Credit Risk Management - Mortgage Loans Held for Portfolio - MPP Credit Enhancements for more information.

Cash and Investments.The following table presents the components of our cash and investments at carrying value ($ amounts in millions):

Components of Cash and Investments	June 30, 2013		December 31, 2012		Change
Cash and short-term investments:
Cash and Due from Banks	$	30	$	105	$	(75	)
Interest-Bearing Deposits	—		—		—
Securities Purchased Under Agreements to Resell	1,450		3,250		(1,800		)
Federal Funds Sold	2,057		2,110		(53		)
Total cash and short-term investments	3,537		5,465		(1,928		)
Investment securities:
AFS securities	3,716		3,980		(264		)
HTM securities	7,244		7,505		(261		)
Total investment securities	10,960		11,485		(525		)
Total Cash and Investments, carrying value	$	14,497	$	16,950	$	(2,453	)

Cash and Short-Term Investments.Cash andshort-term investments totaled $3.5 billion at June 30, 2013, a decrease of 35% compared to December 31, 2012.The decrease was primarily attributable to the higher level maintained at December 31, 2012 due to the economic and political uncertainty at that time. The total outstanding balance and composition of our short-term investment portfolio is influenced by our liquidity needs and the availability of short-term investments at attractive interest rates, relative to our cost of funds. See Liquidity and Capital Resources below for more information.

53

Total Liabilities. Total Liabilities were $37.6 billion at June 30, 2013, a decrease of 4% compared to December 31, 2012. This decrease of $1.4 billion was primarily due to a decrease of $0.8 billion in Consolidated Obligations.

Deposits (Liabilities).Total Deposits were $1.4 billion at June 30, 2013, a decrease of 23% compared to December 31, 2012. These deposits represent a relatively small portion of our funding and vary depending upon market factors, such as the attractiveness of our deposit pricing relative to the rates available on alternative money market instruments, members' investment preferences with respect to the maturity of their investments, and member liquidity. In addition, the balances of one member's principal and interest custodial accounts for GSE remittance payments through our Bank decreased by $0.5 billion at June 30, 2013 compared to December 31, 2012. The balances of these accounts fluctuate from period to period.

Consolidated Obligations.At June 30, 2013, the carrying values of our Discount Notes and CO Bonds totaled $8.9 billion and $26.6 billion, respectively, compared to $8.9 billion and $27.4 billion, respectively, at December 31, 2012. The overall balance of our Consolidated Obligations generally fluctuates in relation to our Total Assets. The carrying value of our Discount Notes was 25% of total Consolidated Obligations at both June 30, 2013 and December 31, 2012. Discount Notes are issued primarily to provide short-term funds while CO Bonds are typically issued to provide intermediate and long-term funding. The composition of our Consolidated Obligations can fluctuate significantly based on comparative changes in their cost levels, supply and demand conditions, demand for Advances, and our balance sheet management strategy. As of June 30, 2013, $11.8 billion or 44% of our outstanding CO Bonds, at par, have a remaining maturity of one year or less. Our funding strategy generally includes a significant portion of CO Bonds maturing in one year or less that are replaced at maturity. See Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources in our 2012 Form 10-Kfor more information about our liquidity and access to the capital markets.

Derivatives. Asof June 30, 2013 and December 31, 2012, we had Derivative Assets, net of collateral held or posted, including accrued interest, with fair values of $3.0 million and $0.8 million, respectively, and Derivative Liabilities, net of collateral held or posted, including accrued interest, with fair values of $197.8 million and $201.1 million, respectively. We classify interest-rate swaps as derivative assets or liabilities according to the positive or negative net fair value of the interest-rate swaps with each counterparty. Increases and decreases in the fair value of derivatives are primarily caused by market changes in the derivatives' underlying interest-rate index.

Total Capital. Total Capital was $2.3 billion at June 30, 2013, an increase of 6% compared to December 31, 2012. This increase was primarily due to a net increase in Capital Stock of $38.0 million, a net increase in Retained Earnings of $80.4 million, and a favorable change in AOCI of $14.0 million. The change in AOCI was primarily due to increases in the fair values of OTTI AFS securities, partially offset by the reclassification of the net realized gains from the sale of AFS securities.

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 $3.5 billion at June 30, 2013. Our short-term investments consist of high-quality, short- and intermediate-term financial instruments. We manage our short-term investment portfolio in response to economic conditions and market events and uncertainties. As a result, the overall level of our short-term investment portfolio may fluctuate accordingly.

We have not identified any known trends, demands, commitments, events or uncertainties that are likely to materially increase or decrease our liquidity.

Capital Resources.

Mandatorily Redeemable Capital Stock. At June 30, 2013, we had $255.7 million in non-member capital stock subject to mandatory redemption, compared to $450.7 million at December 31, 2012. Such amounts included excess stock of $237.8 million and $423.0 million, respectively. See Notes to Financial Statements - Note 13 - Capitalfor additional information.

Excess Stock.During the first quarter of 2013, we repurchased $250 million of excess stock, which was classified as MRCS, from former members (or their successors-in-interest) in accordance with our capital plan dated September 19, 2002 (as amended effective September 5, 2011). This repurchase was undertaken for general capital management purposes. See Notes to Financial Statements - Note 13 - Capitalfor additional information.

54

The following table presents the composition of our excess stock ($ amounts in millions):

Components of Excess Stock	June 30, 2013		December 31, 2012
Member capital stock not subject to outstanding redemption requests	$	356	$	423
Member capital stock subject to outstanding redemption requests	98		101
MRCS	238		423
Total excess capital stock	$	692	$	947

Capital Distributions.On July 29, 2013, our board of directors declared a cash dividend of 3.50% (annualized) on our Capital Stock Putable-Class B-1 and 2.80% (annualized) on our Capital Stock Putable-Class B-2.

Off-Balance Sheet Arrangements

See Notes to Financial Statements - Note 17 - Commitments and Contingenciesfor information on our off-balance sheet arrangements.

Critical Accounting Policies and Estimates

We have identified five accounting policies that we believe 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 relate to:

• OTTI analysis (see Notes to Financial Statements - Note 5 - Other-Than-Temporary Impairment Analysisfor more information);

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

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

• Fair value estimates (see Notes to Financial Statements - Note 16 - Estimated Fair Valuesfor more information); and

• Premiums and discounts and other costs associated with originating or acquiring mortgage loans (see Notes to Financial Statements - Note 7 - Mortgage Loans Held for Portfoliofor more information).

A full discussion of our critical accounting policies and estimates can be found in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Estimates in our 2012 Form 10-K. See below for additional information regarding certain of these policies.

Other-Than-Temporary Impairment Analysis. In addition to evaluating our private-label RMBS under a best estimate scenario, we performed a cash flow analysis for each of these securities under a more stressful housing price scenario. This more stressful scenario was based on a short-term housing price forecast that was decreased five percentage points followed by a recovery path that is 33% lower than the best estimate.

55

The following table presents the results of the best estimate scenario as reported and what the impact on OTTI would have been under the more adverse home price scenario ($ amounts in millions). The classification (prime or Alt-A) is based on the model used to estimate the cash flows for the security, which may not be the same as the classification at the time of origination. Because there is no universally accepted definition of prime, Alt-A or subprime underwriting standards, such classifications are subjective.

	Three Months Ended June 30, 2013
	As Reported					Using Adverse Housing Price Scenario
	Number of			Impairment		Number of			Impairment
	Securities			Related to		Securities			Related to
Classification	Impaired	UPB		Credit Loss (1)		Impaired	UPB		Credit Loss (2)
Prime	—	$	—	$	—	1	$	10	$	—
Alt-A	—	—		—		—	—		—
Subprime	—	—		—		—	—		—
Total	—	$	—	$	—	1	$	10	$	—

⁽¹⁾  There were no credit losses in the best estimate scenario.

⁽²⁾  The impairment related to credit losses using the adverse housing price scenario is less than $1 due to rounding.

The adverse scenario and associated results do not represent our current expectations and, therefore, should not be construed as a prediction of our future results, market conditions or the performance of these securities. Rather, the results from this hypothetical adverse scenario provide a measure of the credit losses that we might incur if home price declines (and subsequent recoveries) are more adverse than those projected in our OTTI evaluation.

Additional information regarding OTTI of our private-label RMBS and ABS is provided in Risk Management - Credit Risk Management - Investments herein.

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 weighted-average collateral recovery rate for the previous 12 months of approximately 54.3% of the original appraised value, further reduced by estimated liquidation costs.

We have also performed our loan loss analysis under an adverse scenario whereby we lowered the weighted-average collateral recovery rate to 45% for delinquent conventional loans and individually evaluated loans. While holding all other assumptions constant, such scenario would have increased our allowance by approximately $5.5 million at June 30, 2013. We consider a weighted-average collateral recovery rate of 45% to be the lowest rate that is reasonably possible to occur over the loss emergence period of 24 months. We continue to monitor the appropriateness of this adverse scenario based on the actual collateral recovery rate. We also evaluate the actual collateral recovery rate against other time periods including the most recent 3- and 6-month periods in order to consider potential trends in the market. Annually, we also consider other adverse scenarios that include loans in earlier stages of delinquency (90 days), higher counterparty losses on claims to our SMI providers, and higher costs to liquidate collateral.

We evaluated these adverse scenarios and determined that the likelihood of incurring losses resulting from these scenarios during the next 24 months was not probable. Therefore, the allowance for loan losses is based upon our best estimate of the probable losses over the next 24 months that would not be recovered from the credit enhancements.

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 results of operations or financial condition.

Legislative and Regulatory Developments.

Finance Agency Regulatory Actions.

Interim Final Rule Regarding Executive Compensation. On May 14, 2013, the Finance Agency published an interim final rule and request for comments, setting forth requirements and processes with respect to compensation provided to executive officers by FHLBanks and the Office of Finance. The interim final rule addresses the authority of the Finance Agency Director to approve, disapprove, modify, prohibit, or direct the withholding of compensation of executive officers of the regulated entities. The rule also addresses the Finance Agency Director's authority to approve, in advance, agreements or contracts of executive officers that provide compensation in connection with termination of employment. The interim final rule prohibits an FHLBank or the Office of Finance from paying compensation to an executive officer that is not reasonable and comparable with compensation paid by similar businesses for similar duties and responsibilities. Failure by an FHLBank or the Office of Finance to comply with the rule may result in supervisory action by the Finance Agency. The interim final rule became effective on June 15, 2013, and comments were due by July 15, 2013.

Proposed Rule Regarding Golden Parachute and Indemnification Payments. On May 14, 2013, the Finance Agency re-published a proposed rule setting forth the standards that the Finance Agency would take into consideration when limiting or prohibiting golden parachute and indemnification payments. The primary impact of this proposed rule would be to better conform existing Finance Agency regulations on golden parachute arrangements with FDIC golden parachute regulations and to further refine limitations on golden parachute payments made by a regulated entity that is assigned a less than satisfactory composite Finance Agency examination rating. Comments on the proposed rule were due by July 15, 2013.

Other Significant Developments.

Housing Finance and Housing GSE Reform.We expect Congress and the Senate to continue their consideration of reforms for United States housing finance and the regulated entities, including the resolution of Fannie Mae and Freddie Mac (together, the "Enterprises"). So far, several new proposals have been offered that would wind down the Enterprises and replace them with a new finance system to support the secondary mortgage market. On June 25, 2013, a bill entitled the "Housing Finance Reform and Taxpayer Protection Actof 2013" ("Housing Finance Reform Act") was introduced in the Senate with bipartisan support. On July 11, 2013, Republican leaders of the House Financial Services Committee submitted a proposal entitled the "Protecting American Taxpayers and Homeowners Act of 2013" ("PATH Act"). Both proposals, if enacted, would have direct implications for the FHLBanks.

While both proposals utilize industry and regulator efforts since the financial crisis to lay the groundwork for a new United States housing finance structure by creating a single securitization platform and establishing national standards for mortgage securitization, the proposals differ on the role of the Federal government in the revamped housing finance structure. The Housing Finance Reform Act would establish the Federal Mortgage Insurance Corporation ("FMIC") as an independent agency in the Federal government, replacing the Finance Agency as the primary regulator of the FHLBanks. The FMIC would facilitate the securitization of eligible mortgages by insuring covered securities, in a catastrophic risk position. The FHLBanks, or a new subsidiary, would be authorized to apply to become an approved issuer of covered securities to facilitate access to the secondary market for smaller community mortgage lenders. Any covered MBS issued by the FHLBanks or the new subsidiary would not be issued as a consolidated debt instrument and would not be treated as a joint and several obligation of any FHLBank that has not elected to participate in such issuance.

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

57

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

Any fundamental changes to the United States housing finance system could have consequences for the FHLBanks and our ability to provide readily accessible liquidity to our members. However, it is impossible to determine at this time whether or when legislation will be enacted for housing GSE or housing finance reform. The ultimate effects of these efforts on the FHLBanks are unknown and will depend on the legislation or other changes, if any, that ultimately are promulgated.

Final Rule and Guidance on the Supervision and Regulation of Certain Nonbank Financial Companies. The Financial Stability Oversight Council ("Oversight Council") issued a final rule and guidance effective May 11, 2012 on the standards and procedures the Oversight Council employs in determining whether to designate a nonbank financial company for supervision by the Federal Reserve and to make it subject to certain, prudential standards. The guidance issued with this final rule provides that the Oversight Council expects in making its determinations to use a process consisting of:

• A first stage that will identify those nonbank financial companies that have $50 billion or more of total consolidated assets (as of June 30, 2013, the Bank had $39.9 billion in total assets) and exceed any one of five threshold indicators of interconnectedness or susceptibility to material financial distress, including whether a company has $20 billion or more in total debt outstanding (as of June 30, 2013, the Bank had $35.5 billion in total outstanding Consolidated Obligations, the Bank's principal form of outstanding debt);

• A second stage involving a robust analysis of the potential threat that the subject nonbank financial company could pose to United States financial stability based on additional quantitative and qualitative factors that are both industry and company specific; and

• A third stage analyzing the subject nonbank financial company using information collected directly from it.

The final rule provides that, in making its determinations, the Oversight Council will consider as one factor whether the nonbank financial company is subject to oversight by a primary financial regulatory agency (for us, the Finance Agency). A nonbank financial company that the Oversight Council proposes to designate for additional supervision (for example, periodic stress testing) and prudential standards (such as heightened liquidity or capital requirements) under this rule has the opportunity to contest the designation. If we are designated by the Oversight Council for supervision by the Federal Reserve and subject to additional Federal Reserve prudential standards, our operations and business could be adversely impacted by any resulting additional costs, liquidity or capital requirements, or restrictions on business activities.

On April 5, 2013, the Federal Reserve published a final rule that establishes the requirements for determining when a company is "predominately engaged in financial activities." The final rule provides that a company is "predominantly engaged in financial activities" and thus a "nonbank financial company" if:

• as determined in accordance with applicable accounting standards, (i) the consolidated annual gross financial revenues of the company in either of its two most recently completed fiscal years represent 85% or more of the company's consolidated annual gross revenues in that fiscal year, or (ii) the company's consolidated total financial assets as of the end of either of its two most recently completed fiscal years represent 85% or more of the company's consolidated total assets as of the end that fiscal year; or

• based on all the facts and circumstances, it is determined by the Oversight Council, with respect to the definition of a "nonbank financial company," or the Federal Reserve, with respect to the definition of a "significant nonbank financial company," that (i) the consolidated annual gross financial revenues of the company represent 85% or more of the company's consolidated annual gross revenues, or (ii) the consolidated total financial assets of the company represent 85% or more of the company's consolidated total assets.

Under this recently published final rule, we may be deemed to be a "nonbank financial company."

58

The final rule also defines the terms "significant nonbank financial company" to mean (i) any nonbank financial company supervised by the Federal Reserve; and (ii) any other nonbank financial company that had $50 billion or more in total consolidated assets as of the end of its most recently completed fiscal year; and "significant bank holding company" to mean "any bank holding company or company that is, or is treated in the United States as, a bank holding company, that had $50 billion or more in total consolidated assets as of the end of the most recently completed calendar year."

If an FHLBank is designated for supervision by the Federal Reserve (and therefore a significant nonbank financial company), the designated FHLBank would be subject to increased supervision and oversight as described above. The final rule became effective on May 6, 2013. We have no way of determining when the Oversight Council may complete its designation process under the final rule or what those designations will be.

Money Market Mutual Fund ("MMF") Reform. The Oversight Council has issued certain proposed recommendations for structural reforms of MMFs, stating that such reforms are intended to address the structural vulnerabilities of MMFs. In addition, on June 19, 2013 the SEC proposed two alternatives for amending rules that govern MMFs under the Investment Company Act of 1940. The first alternative proposal would require non-government institutional MMFs to sell and redeem shares based on the current market-based value of the securities in their underlying portfolios. The second alternative proposal would require MMFs to generally impose a liquidity fee if a fund's liquidity levels fall below a specified threshold and would permit the funds to suspend redemptions temporarily. As government money market funds are exempt from implementing these changes, these potential changes are not expected to have negative consequences for FHLBank debt demand. However, the potential exists for refinement of the proposed changes once the comment period ends. MMFs historically have been important buyers of FHLBank System Consolidated Obligations, so the demand for FHLBank System Consolidated Obligations may be impacted by the structural reform ultimately adopted.

Consumer Financial Protection Bureau ("CFPB") Final Ability to Repay and Qualified Mortgage Rule Amendments. The CFPB issued a final rule with an effective date of January 14, 2014 establishing new standards for mortgage lenders to follow during the loan approval process to determine whether a borrower has the ability to repay the mortgage. Qualified Mortgages ("QMs") are a subset of home loans where the borrower is presumed to have the ability to repay the mortgage. QMs include mortgage loans that are eligible for Fannie Mae or Freddie Mac to purchase or otherwise satisfy certain underwriting standards. On May 6, 2013, the Finance Agency announced that it is directing Fannie Mae and Freddie Mac, beginning January 10, 2014, to limit their future mortgage acquisitions to loans that are QMs (including those that meet a special or temporary QM definition) or are exempt from the CFPB's ability-to-pay requirements. We are reviewing this announcement for its potential impacts on our business operations.

On May 29, 2013, and July 10, 2013, the CFPB issued additional final rules to amend the final Ability to Repay and QM rule. Among other things, the additional rules (i) allow certain small creditors (generally those with assets under $2 billion) in rural or underserved areas to treat first lien balloon mortgage loans as QMs and (ii) exempt mortgages made by certain Community Development Financial Institutions, Community Housing Development Organizations, Downpayment Assistance Providers of Secondary Financing; and nonprofit organizations designated under Section 501(c)(3) of the Internal Revenue Code from the Ability to Repay (and QM) requirements.

The QM safe harbor from liability could incentivize lenders, including our members, to limit their mortgage lending to safe harbor QMs or otherwise reduce their origination of mortgage loans that are not safe harbor QMs. This could reduce the overall level of members' mortgage lending and, in turn, reduce demand for FHLBank Advances. Additionally, the value and marketability of mortgage loans that are not safe harbor QMs, including those pledged as collateral to secure Advances, may be adversely affected.

Basel Committee on Banking Supervision - Capital Framework. In July 2013, the Federal Reserve and the Officer of the Comptroller of the Currency adopted a final rule and the FDIC adopted an interim final rule establishing new minimum capital standards for financial institutions to incorporate the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision. The new capital framework includes, among other things:

• a new common equity tier 1 minimum capital requirement, a higher minimum tier 1 capital requirement and an additional capital conservation buffer;

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

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

59

The new framework could require some FHLBank member banks to divest assets in order to comply with the more stringent capital and liquidity requirements, thereby tending to decrease their need for advances. The requirements may also adversely impact investor demand for Consolidated Obligations to the extent that impacted institutions divest or limit their investments in Consolidated Obligations. Conversely, the new requirements could incent FHLBank members to take term advances to create and maintain balance sheet liquidity. Most FHLBank member banks must be in compliance with the final rule by January 1, 2015, although some larger member banks must comply by January 1, 2014.

Risk Management

We are exposed to a number of risks in pursuing our business objectives. These risks may be broadly classified as market, credit, liquidity, operations, and business. Market risk is discussed in detail 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 2012 Form 10-K for more detailed information.

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

Advances.Our credit risk is magnified due to the concentration of Advances in a few borrowers. As of June 30, 2013, our top three borrowers held 39% of total Advances outstanding, at par. Because of this concentration in Advances, 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.

We maintain a credit products borrowing threshold of 50% of a depository member's adjusted assets, defined as total assets less borrowings from all sources. Effective June 3, 2013, the borrowing threshold for insurance company members is 15% of general account assets less borrowed money. Members whose total credit products exceed such thresholds are monitored more closely, are reported to senior management on a regular basis and require additional approval by our Bank as provided for in our credit policy. Credit underwriting will make a recommendation based upon a number of factors that may include the member's credit rating, collateral quality, and earnings stability. 

Advances to our insurance company members have increased from 49% of total Advances, at par as of December 31, 2012, to 55% of total Advances, at par as of June 30, 2013. As of June 30, 2013, four of our five largest Advance borrowers were insurance companies. In addition, as of December 31, 2012, approximately 80% of total assets owned by institutions eligible for membership in our district were owned by insurance companies. Therefore, we expect that Advances outstanding to our insurance company members and the relative percentage of their Advances to the total will continue to increase. Although insurance companies represent significant growth opportunities, they have different risk characteristics than our depository members. Some of the ways we mitigate this risk include requiring insurance companies to deliver collateral to us or our custodian, with the majority of that collateral being marketable securities, and using an insurance industry-specific credit scorecard as part of our ongoing evaluation of our insurance company members' financial strength.

60

Investments. We are also exposed to credit risk through our investment portfolios. The Risk Management Policy approved by our board of directors restricts the acquisition of investments to high-quality, short-term money market instruments and highly-rated long-term securities.

Short-Term Investments. At June 30, 2013, our unsecured credit exposure, including accrued interest related to short-term money-market instruments, was $2.1 billion to five counterparties and issuers, all of which was for Federal Funds Sold that mature overnight. 

As of June 30, 2013, our unsecured investment credit exposure to United States branches and agency offices of foreign commercial banks was limited to Federal Funds Sold. Unsecured transactions can be conducted only with counterparties that are domiciled in countries that maintain a long-term sovereign rating from S&P of AA or higher. None of our Federal Funds Sold were with our members at June 30, 2013.

The following table presents the unsecured investment credit exposures to private counterparties, categorized by the domicile of the counterparty's parent, based on the lowest of the NRSRO long-term credit ratings of the counterparty stated in terms of the S&P equivalent. The table does not reflect the foreign sovereign government's credit rating ($ amounts in millions):

Total unsecured credit exposure	$	1,305	$	752	$	2,057

⁽¹⁾  Includes United States subsidiaries of foreign commercial banks.

Long-Term Investments. Our long-term investments include RMBS guaranteed by the housing GSEs (Fannie Mae and Freddie Mac), other United States obligations - guaranteed RMBS (Ginnie Mae), and corporate debentures issued by the TVA and other GSEs.

A Finance Agency regulation provides that the total value of our investments in MBS and ABS, calculated using amortized historical cost, must not exceed 300% of our total regulatory capital, consisting of Retained Earnings, Class B Capital Stock, and MRCS, as of the day we purchase the securities, based on the capital amount most recently reported to the Finance Agency. If our outstanding investments in MBS and ABS exceed the limitation at any time, but were in compliance at the time we purchased the investments, we would not be considered out of compliance with the regulation, but we would not be permitted to purchase additional investments in MBS or ABS until these outstanding investments were within the capital limitation. These investments, as a percentage of total regulatory capital, were 287% at June 30, 2013, compared to 295% at December 31, 2012. Generally, our goal is to maintain these investments near the 300% limit.

61

The following table presents the carrying values of our investments by credit rating, grouped by investment category. Applicable rating levels are determined using the lowest relevant long-term rating from S&P, Moody's and Fitch 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 ($ amounts in millions):

Private-Label RMBS and ABS. RMBS and ABS are classified as prime, Alt-A or subprime based on the originator's classification at the time of origination or based on classification by an NRSRO upon issuance. Because there is no universally accepted definition of prime, Alt-A or subprime underwriting standards, such classifications are subjective. All RMBS and ABS were rated AAA at the date of purchase.  

Our private-label RMBS and ABS are backed by collateral located only in the United States and the District of Columbia. The top five states, by percentage of collateral located in those states as of June 30, 2013, were California (62%), New York (6%), Florida (5%), New Jersey (2%), and Connecticut (2%).

The table below presents the UPB of our private-label RMBS and ABS by credit rating, based on the lowest of Moody's, S&P, or Fitch ratings each stated in terms of the S&P equivalent, as well as amortized cost, estimated fair value, and OTTI losses by year of securitization as of June 30, 2013 ($ amounts in millions):

Total private-label RMBS and ABS, at UPB	$	182	$	587	$	769	$	293	$	721	$	1,014

⁽¹⁾  We classify our private-label RMBS and ABS as prime, Alt-A and subprime based on the originator's classification at the time of origination or based on classification by an NRSRO upon issuance. Because there is no universally accepted definition of prime, Alt-A or subprime underwriting standards, such classifications are subjective.

⁽²⁾  Variable-rate private-label RMBS and ABS include those with a contractual coupon rate that, prior to contractual maturity, is either scheduled to change or is subject to change.

⁽³⁾  All variable-rate prime loans are hybrid adjustable-rate mortgage securities.

OTTI Evaluation Process.A significant modeling assumption used to determine whether a security is OTTI is the forecast of future housing price changes for the relevant states and Core Based Statistical Areas, which are based upon an assessment of the individual housing markets.

Our housing price forecast includes a short-term housing price forecast using whole percentages, with projected changes ranging from (5.0)% to 7.0% over the twelve month period beginning April 1, 2013. For the vast majority of housing markets, the short-term forecast has changes from (3.0)% to 5.0%. Thereafter, home prices are projected to recover (or continue to recover) using one of five different recovery paths.

The following table presents projected home price recovery by months following the short-term housing price forecast:

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

64

The following tables present additional significant modeling assumptions used to determine whether a security was OTTI during the second quarter of 2013, as well as the related current credit enhancement as of June 30, 2013. Credit enhancement is defined as the percentage of subordinated tranches and over-collateralization, if any, in a security structure that will generally absorb losses before we will experience a loss on the security. A credit enhancement percentage of zero reflects securities that have no remaining credit support and are likely to have experienced an actual principal loss. The calculated averages represent the dollar-weighted averages of all of the private-label RMBS and ABS in each category shown. RMBS and ABS are classified as prime, Alt-A or subprime based on the model used to estimate the cash flows for the security, which may not be the same as the classification by the rating agency at the time of origination ($ amounts in millions).

Mortgage Loans Held for Portfolio.

MPP Credit Enhancements. Credit enhancements for conventional MPP loans include (in order of priority):

• PMI (when applicable for the purchase of mortgages with an initial loan-to-value ratio of over 80% at the time of purchase);

• LRA; and

• SMI (as applicable) purchased by the seller from a third-party provider naming us as the beneficiary.

Apart from these credit enhancements, we have other contractual and legal remedies available to us to manage some risks posed within our mortgage loans portfolio, such as the risk that a seller (or its successor-in-interest) may breach or be unwilling or unable to perform on its contractual obligations to us. During the second quarter of 2013, we exercised our statutory and contractual lien on excess capital stock in the amount of $0.4 million owned by a former member in order to enforce our contractual rights under our MPP and our Advances, Pledge and Security Agreement regarding mortgage loans sold to us.

Primary Mortgage Insurance.The following table presents the PMI providers and related PMI coverage amount on seriously delinquent loans held in our portfolio as of June 30, 2013, and the mortgage insurance company credit ratings as of July 31, 2013 ($ amounts in millions):

⁽²⁾  Seriously delinquent loans include loans that are 90 days or more past due or in the process of foreclosure.

⁽³⁾   On August 3, 2011, we announced that we would no longer accept Republic Mortgage Insurance Company as a provider of PMI, effective with mandatory delivery contracts committed on or after August 1, 2011. On January 20, 2012, the North Carolina Department of Insurance took possession and control of Republic Mortgage Insurance Company, a subsidiary of Old Republic International Corporation, and, beginning January 19, 2012, Republic Mortgage Insurance Company was authorized to pay only 50% of its claim amounts, with the remaining amount to be paid at a future date when funds become available. On December 3, 2012, Republic Mortgage Insurance Company announced regulatory approval of a plan to pay 60% of its claims amounts for claims settled subsequent to January 19, 2012.

⁽⁴⁾  On October 20, 2011, the Arizona Department of Insurance took possession and control of PMI Mortgage Insurance Co. Beginning October 24, 2011, PMI Mortgage Insurance Co. paid only 50% of its claim amountswith the remaining amount deferred until the company is liquidated. On April 5, 2013, PMI Mortgage Insurance Company announced regulatory approval of a plan to pay 55% of its claims amounts for claims settled subsequent to October 24, 2011.

Credit Risk Exposure to Supplemental Mortgage Insurance Providers. As of June 30, 2013, we were the beneficiary of SMI coverage under our original MPP on mortgage pools with a total UPB of $2.7 billion. Two mortgage insurance companies provide all of the SMI coverage. The following table presents the SMI exposure and the lowest credit rating and outlook of S&P, Moody's and Fitch each stated in terms of the S&P equivalent as of July 31, 2013 ($ amounts in millions):

MPP and MPF Loan Concentration. The mortgage loans purchased through the MPP and the participation interests purchased through the MPF program are currently dispersed across 50 states and the District of Columbia. No single zip code represented more than 1% of mortgage loans outstanding at June 30, 2013 or December 31, 2012. As of June 30, 2013, 31% and 25% of our conventional mortgage loans were concentrated in our district states of Indiana and Michigan, respectively. It is likely that the concentration of mortgage loans in Indiana and Michigan will increase in the future due to the loss of the three largest sellers in 2006 - 2007 that were our primary sources of nationwide mortgages. The median outstanding size of our mortgage loans was approximately $131 thousand at June 30, 2013 and approximately $130 thousand at December 31, 2012. 

MPP and MPF Credit Performance. The serious delinquency rate for the MPP FHA mortgages was 0.37% at June 30, 2013, compared to 0.38% at December 31, 2012. We rely on insurance provided by the FHA, which generally provides coverage for 100% of the principal balance of the underlying mortgage loan and defaulted interest at the debenture rate. However, we would receive defaulted interest at the contractual rate from the servicer.

The serious delinquency rate for MPP conventional mortgages was 1.91% at June 30, 2013, compared to 2.15% at December 31, 2012. Both rates were below the national serious delinquency rate. There was one seriously delinquent MPF loan at June 30, 2013. See Notes to Financial Statements - Note 8 - Allowance for Credit Losses for more information.

Derivatives.The Dodd-Frank Wall Street Reform and Consumer Protection Act, as amended, provides for new statutory and regulatory requirements for derivatives transactions, including those we use to hedge our interest rate and other risks. Since June 10, 2013, we have been required to clear certain interest rate swaps that fall within the scope of the first mandatory clearing determination.

We are subject to credit risk due to the potential of nonperformance by the counterparties to our derivative agreements. Our derivative transactions are either (i) bilateral derivatives, which are traded over-the-counter with a counterparty, or (ii) cleared derivatives, which are over-the-counter cleared through a Futures Commission Merchant with a Clearinghouse.

Bilateral Derivatives. We are subject to non-performance by the counterparties to our derivative agreements.We require collateral agreements with collateral delivery thresholds on a majority of bilateral derivatives. The amount of net unsecured credit exposure that is permissible with respect to each counterparty depends on the credit rating of that counterparty. A counterparty must deliver collateral to us if the total market value of our exposure to that counterparty rises above a specific trigger point.

67

Cleared Derivatives. We are subject to credit risk due to the potential nonperformance by the Clearinghouse because we are required to post initial and variation margin through the clearing member, on behalf of the Clearinghouse, which exposes us to institutional credit risk if either the clearing member or the Clearinghouse fails to meet its obligations. Collateral is required to be posted daily for changes in the value of cleared derivatives to mitigate each counterparty's credit risk. 

In addition, all derivative transactions are subject to new mandatory reporting and recordkeeping requirements. See Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Recent Accounting and Regulatory Developments in our 2012 Form 10-K for more information.

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Measuring Market Risks

We utilize multiple risk measurements, including duration of equity, duration gap, convexity, VaR, earnings at risk, and changes in market value of equity, to evaluate market risk. Periodically, stress tests are conducted 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.

Duration of Equity. The following table presents the effective duration of equity levels for our total position, which are subject to internal policy guidelines:

Date	-200 bps (1)	0 bps	+200 bps
June 30, 2013	2.0 years	(2.9) years	0.6 years
December 31, 2012	(4.2) years	0.3 years	0.4 years

⁽¹⁾  Our internal policy guidelines provide for the calculation of the duration of equity in a low-rate environment to be based on the Finance Agency Advisory Bulletin 03-09, as modified September 3, 2008. Under these guidelines, our duration of equity was (2.9) years at June 30, 2013 and 0.3 years at December 31, 2012.

We were in compliance with the duration of equity limits established at both dates. The decrease in the base case (0 bps) duration of equity level at June 30, 2013 compared to December 31, 2012 was primarily due to the CO curve shifting upward more than the LIBOR curve, which extended the duration of our debt more than the duration of our assets.

Duration Gap. The duration gap was (3.7) months at June 30, 2013, compared to (0.7) months at December 31, 2012.

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 these historical prices and market rates. The table below presents the VaR ($ amounts in millions):

Date	VaR
June 30, 2013	$	246
December 31, 2012	106

Changes in the Ratio of Market Value to Book Value of Equity between Base Rates and Shift Scenarios. We measure potential changes in the market value to book value of equity based on the current month-end level of rates versus the ratio of market value to book value of equity under large parallel rate shifts. This measurement provides information related to the sensitivity of our interest-rate position. The table below presents changes in the ratio of market value to book value of equity from the base rates: 

Date	-200 bps		+200 bps
June 30, 2013	(5.5	)%	1.9	%
December 31, 2012	(3.1	)%	1.3	%

See Item 7A. Quantitative and Qualitative Disclosures About Market Risk - Use of Derivative Hedges in our 2012 Form 10-K for more information about our use of derivative hedges.

69

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 June 30, 2013, 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 June 30, 2013.

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 the fact that there are 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 that 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 also is 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

We are unaware of any potential claims against us that could be material.

Private-Label Mortgage-Backed Securities Litigation

On October 15, 2010, we filed a complaint in the Superior Court of Marion County, Indiana, relating to private-label mortgage-backed securities we purchased in the aggregate original principal amount of approximately $2.9 billion. The complaint, which was amended in 2011, is an action for rescission and damages and asserted claims for negligent misrepresentation and violations of state and federal securities laws occurring in connection with the sale of these private-label mortgage-backed securities.

On January 11, 2013, following our motion for voluntary dismissal, the Court dismissed all claims concerning four bonds which had paid in full. The dismissal as to these four bonds did not result in the dismissal of any Defendants from the action.

70

Item 1A.  RISK FACTORS

Except for an update to the following risk factors, there have been no material changes in the risk factors described in Item 1A. Risk Factors of our 2012 Form 10-K.

Economic Conditions Could Have an Adverse Effect on Our Business, Liquidity, Financial Condition, and Results of Operations.

Our business, liquidity, financial condition, and results of operations are sensitive to general international and domestic business and economic conditions, such as changes in short-term and long-term interest rates and the money supply, inflation, volatility in both debt and equity capital markets, and the strength of the local economies in which we conduct business.

Our district is comprised of the states of Indiana and Michigan. Economic data for our district have generally been unfavorable compared to national data, with unemployment and foreclosure rates higher than national rates. On July 18, 2013, the city of Detroit filed for bankruptcy protection under Chapter 9 of the bankruptcy code. While there have been legal challenges to the filing, this case is proceeding and could continue for some time. Although we have no direct credit exposure to the city of Detroit, we do not know how this case could affect the state of Michigan and its economy or our members. If Michigan's economy or our members are adversely affected, our financial condition and results of operations could be negatively impacted. Conversely, if the bankruptcy effectively stabilizes the city of Detroit, our business could be favorably affected in the long term.

Our Credit Rating, the Credit Rating of One or More of the Other FHLBanks, or the Credit Rating of the Consolidated Obligations Could be Lowered, Which Could Adversely Impact Our Cost of Funds, Our Ability to Access the Capital Markets, and/or Our Ability to Enter Into Derivative Instrument Transactions on Acceptable Terms.

On June 10, 2013, S&P affirmed the AA+ long-term senior debt rating of the FHLBank System and revised its outlook on our Consolidated Obligations from negative to stable. S&P also affirmed the A-1+ short-term debt ratings of the FHLBank System. The outlook on the FHLBank System was revised to stable reflecting the stable outlook of the United States government. In the application of S&P's Government Related Entities criteria, the ratings of the FHLBank System are constrained by the long-term sovereign rating of the United States government. On July 18, 2013, Moody's affirmed the Aaa long-term senior debt rating of the FHLBank System and revised its outlook on our Consolidated Obligations from negative to stable. Moody's also affirmed the Prime-1 short-term debt ratings of the FHLBank System. The outlook on the FHLBank System was revised to stable as a result of the update of the outlook of the United States government to stable.

Although previous negative rating actions have not had an impact on our funding costs, uncertainty still remains regarding possible longer-term effects resulting from rating actions. Our cost of issuing debt could be adversely affected if our credit rating or the credit ratings of one or more other FHLBanks are lowered. Any future downgrades in our credit ratings and outlook, especially a downgrade to AA or equivalent, could result in higher funding costs or disruptions in our access to capital markets, including additional collateral posting requirements under certain derivative instrument agreements. Furthermore, member demand for certain of our products could possibly weaken. To the extent that we cannot access funding when needed on acceptable terms to effectively manage our cost of funds, our financial condition and results of operations and the value of membership in our Bank may be negatively affected.

Managing Credit Risk on Derivatives. We are subject to credit risk due to the risk of nonperformance by counterparties to our derivative agreements. We manage counterparty credit risk through credit analysis, collateral requirements and adherence to the requirements set forth in our policies and Finance Agency regulations.

For bilateral derivatives, the degree of credit risk depends on the extent to which master netting arrangements are included in such contracts to mitigate the risk. We require collateral agreements with collateral delivery thresholds on the majority of our bilateral derivatives. Additionally, collateral related to derivatives with member institutions includes collateral assigned to us, as evidenced by a written security agreement and held by the member institution for our benefit.

For cleared derivatives, the Clearinghouse is our counterparty and, therefore, our credit risk exposure is with a central counterparty rather than individual counterparties. Collateral is required to be posted daily for changes in the value of cleared derivatives to mitigate each counterparty's credit risk. The additional requirement that we post initial and variation margin through the clearing member, for the benefit of the Clearinghouse, exposes us to institutional credit risk in the event that the clearing member or Clearinghouse fails to meet its obligations.

See Note 16 - Estimated Fair Values for discussion regarding our fair value methodology for derivative assets and liabilities, including an evaluation of the potential for the estimated fair value of these instruments to be affected by counterparty credit risk.

We have credit support agreements for our bilateral derivatives 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 bilateral derivative instruments in net liability positions. The aggregate estimated fair value of all bilateral 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 June 30, 2013 was $605,962 for which we have posted collateral, including accrued interest, with an estimated fair value of $410,381 in the normal course of business. In addition, we held other derivative instruments in a net liability position of $2,261 that are not subject to credit support agreements containing credit-risk related contingent features. If our credit rating had been lowered by an NRSRO (from an S&P equivalent of AA+ to AA), we could have been required to deliver up to an additional $52,852 of collateral (at estimated fair value) to our derivative counterparties at June 30, 2013.

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

Inclusion of the Fed Funds Effective Swap Rate (or OIS) as a Benchmark Interest Rate for Hedge Accounting Purposes. On July 17, 2013, the FASB amended existing guidance to include the Fed Funds Effective Swap Rate, also referred to as OIS, as a United States benchmark interest rate for hedge accounting purposes. Including OIS as an acceptable United States benchmark interest rate, in addition to United States Treasuries and LIBOR, will provide a more comprehensive spectrum of interest rate resets to use as the designated benchmark interest rate risk component under the hedge accounting guidance. The amendments also remove the restriction on using different benchmark interest rates for similar hedges. The amendments apply to all entities that elect to apply hedge accounting of the benchmark interest rate, and are effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. We are currently in the process of evaluating the potential effects of this guidance on our hedging strategies.

Joint and Several Liability Arrangements. On February 28, 2013, the FASB issued guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date. This guidance requires an entity to measure these obligations as the sum of (i) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (ii) any additional amount the reporting entity expects to pay on behalf of its co-obligors. In addition, this guidance requires an entity to disclose the nature and the amount of the obligation as well as other information about those obligations. This guidance is effective for interim and annual periods beginning on or after December 15, 2013 and should be applied retrospectively to obligations with joint and several liabilities existing at the beginning of an entity's fiscal year of adoption. This guidance will not have any effect on our financial condition, results of operations or cash flows.

Presentation of Comprehensive Income. On February 5, 2013, the FASB issued guidance to improve the transparency of reporting classifications out of AOCI. This guidance does not change the current requirements for reporting net income or comprehensive income in financial statements. However, it does require us to provide information about the amounts reclassified out of AOCI by component. In addition, we are required to present, either on the face of the financial statement where net income is presented or in the notes, significant amounts reclassified out of AOCI. These amounts must be presented based on the respective lines of net income if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, we are required to cross-reference to other required disclosures that provide additional detail about these other amounts. This guidance became effective for interim and annual periods beginning on January 1, 2013 and was applied prospectively. The adoption of this guidance resulted in additional financial statement disclosures, but did not have any effect on our financial condition, results of operations or cash flows. See Note 14 - Accumulated Other Comprehensive Income (Loss)for additional disclosures required by this guidance.

Disclosures about Offsetting Assets and Liabilities.On December 16, 2011, the FASB issued common disclosure requirements intended to help investors and other financial statement users better assess the effect or potential effect of offsetting arrangements on a company's financial position. This guidance was amended on January 31, 2013 to clarify that its scope includes only certain financial instruments that are either offset on the statement of condition or are subject to an enforceable master netting arrangement or similar agreement. This guidance requires us to disclose both gross and net information about derivative, repurchase and security lending instruments that meet this criteria. This guidance, as amended, became effective for interim and annual periods beginning on January 1, 2013, and was applied retrospectively for all comparative periods presented. The adoption of this guidance resulted in expanded interim and annual financial statement disclosures, but did not have any effect on our financial condition, results of operations or cash flows. See Note 9 - Derivatives and Hedging Activities for additional disclosures required by this guidance.

Advisory Bulletin 2012-02.On April 9, 2012, the Finance Agency issued Advisory Bulletin 2012-02, Framework for Adversely Classifying Loans, Other Real Estate Owned, and Other Assets and Listing Assets for Special Mention ("AB-2012-02"). The guidance establishes a standard and uniform methodology for adversely classifying certain assets other than investment securities, and prescribes the timing of asset charge-offs based on these classifications. Such classification methodology and accounting treatment differ from our current methodology and accounting policy. AB-2012-02 states that it was effective upon issuance. However, the Finance Agency issued additional guidance that extended the effective date for classification purposes to January 1, 2014; and the effective date for financial reporting purposes to January 1, 2015. We are in the process of implementing this guidance. While we are evaluating the effect of this guidance on our financial condition, results of operations and cash flows, we do not expect it to be material.

Note 16 - Estimated Fair Values

We review the fair value hierarchy classifications on a quarterly basis. Changes in the observability of the inputs may result in a reclassification of certain assets or liabilities. Such reclassifications are reported as transfers in/out at estimated fair value as of the beginning of the quarter in which the changes occur. As described below, we reclassified six AFS securities from Level 3 to Level 2 during the six months ended June 30, 2013. There were no such reclassifications during the three months ended June 30, 2013 and the three and six months ended June 30, 2012.

The following tables present the carrying value and estimated fair value of each of our financial assets and liabilities. The total of the estimated fair values does not represent an estimate of our overall market value as a going concern, which would take into account future business opportunities and the net profitability of assets and liabilities among other considerations.

Summary of Valuation Techniques and Significant Inputs. A description of the valuation techniques, significant inputs, and levels of fair value hierarchy is disclosed in Note 19 - Estimated Fair Valuesinour 2012 Form 10-K, and no changes have been made in the current year, except as disclosed below.

Derivative Assets/Liabilities. The estimated fair values of our derivatives are adjusted for counterparty nonperformance risk, particularly credit risk, as appropriate. Our nonperformance risk adjustment is computed using observable credit default swap spreads and estimated probability default rates applied to our exposure after taking into consideration collateral held or placed. The nonperformance risk adjustment is not material to our derivative valuations or financial statements.

Estimated Fair Value Measurements. The following tables present by level within the fair value hierarchy the estimated fair value of our financial assets and liabilities that are recorded at estimated fair value on a recurring basis on our Statement of Condition. We did not have any financial assets or liabilities recorded at estimated fair value on a non-recurring basis on our Statement of Condition as of June 30, 2013 or December 31, 2012.

Level 3 Disclosures for All Assets and Liabilities that are Measured at Fair Value on a Recurring Basis. The table below presents a rollforward of our AFS private-label RMBS measured at estimated fair value on a recurring basis using Level 3 significant inputs. The estimated fair values for the private-label RMBS were valued using a pricing source, such as a dealer quote or comparable security price, for which the significant unobservable inputs used to determine the price were not reasonably available.

We classified the six securities we sold on April 4, 2013 as Level 2 within the fair value hierarchy as of March 31, 2013 because the estimated fair values were derived from and corroborated by the sales prices in actual market transactions. The total fair value of these six securities that we transferred from Level 3 to Level 2 was $124,179 as of January 1, 2013, the beginning of the quarter in which the transfer occurred.

Note 18 - Transactions with Related Parties

For financial reporting purposes, we define related parties as those members, and former members and their affiliates, with capital stock outstanding in excess of 10% of our total outstanding Capital Stock and MRCS. Transactions with such related parties are entered into in the normal course of business and are subject to the same eligibility and credit criteria, as well as the same terms and conditions, as other similar transactions. In addition, under our Capital Plan, our members (including directors' financial institutions) have an activity-based Capital Stock requirement pursuant to which they purchase additional Capital Stock in specified amounts (generally expressed as a percentage of the transaction amount) when they obtain Advances from us or in certain cases sell mortgage loans to us.

The following table presents the outstanding balances with respect to transactions with related parties and their balance as a percent of the total balance on our Statement of Condition.

Rollforward of Allowance for Credit Losses on Mortgage Loans [Table Text Block]

The tables below present a rollforward of our allowance for loan losses on mortgage loans, the allowance for loan losses by impairment methodology, and the recorded investment in mortgage loans by impairment methodology. The recorded investment in a loan is the UPB of the loan, adjusted for accrued interest, net of 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 write-downs. The recorded investment is not net of any valuation allowance.

⁽¹⁾  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.

⁽²⁾  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 amounts that were previously paid in full by the servicers on conventional loans that are pending resolution of potential loss claims. Many FHA loans are repurchased by the servicers when they reach 90 days or more delinquent status, similar to the rules for servicers of Ginnie Mae MBS, resulting in the lower serious delinquency rate for FHA loans.

⁽³⁾  Although our past due scheduled/scheduled MPP loans are classified as loans past due 90 days or more based on the mortgagor's payment status, we do not consider these loans to be non-accrual.

Total Securities Other-than-Temporarily Impaired during the Life of the Security [Table Text Block]

The following table presents the June 30, 2013 classification and balances of OTTI securities impaired prior to June 30, 2013 (i.e., life to date) but not necessarily as of June 30, 2013. Securities are classified based on the originator's classification at the time of origination or based on the classification by the NRSROs upon issuance. Because there is no universally accepted definition of prime, Alt-A or subprime underwriting standards, such classifications are subjective.

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

Realized Gains and Losses. The following table presents the proceeds, previously recognized OTTI credit losses including accretion, and gross realized gains and losses related to the sale of six OTTI AFS securities, only one of which was in an unrealized loss position. In the first quarter of 2013, we recorded an OTTI credit charge for this security, representing the entire difference between our amortized cost basis and its estimated fair value, which resulted in no gross realized losses related to the sale. We compute gains and losses on sales of investment securities using the specific identification method.

As of June 30, 2013, we had no intention of selling the remaining 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.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 1 - Summary of Significant Accounting Policies

Basis of Presentation. The accompanying interim financial statements of the Federal Home Loan Bank of Indianapolis have been prepared in accordance with GAAP for interim financial information and with the instructions provided by the SEC. Accordingly, they do not include all of the information and disclosures required by GAAP for complete financial statements. The interim financial statements presented herein should be read in conjunction with our audited financial statements and notes thereto, which are included in our 2012 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 fiscal year or any other interim period.

Our significant accounting policies and certain other disclosures are set forth in Note 1 - Summary of Significant Accounting Policiesin our 2012 Form 10-K. There have been no material changes to these policies through June 30, 2013.

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

Reclassifications. We have reclassified certain amounts from the prior periods to conform to the current period presentation. These reclassifications had no effect on Net Income, Total Comprehensive Income, Total Assets, Total Capital, or Cash Flows.

Use of Estimates.The preparation of financial statements in accordance with GAAP requires us 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. Actual results could differ significantly from these estimates.

Financial Instruments with Legal Right of Offset.We present certain financial instruments, including derivative instruments and securities purchased under agreements to resell, on a net basis when they have a legal right of offset and all other requirements for netting are met (collectively referred to as the netting requirements). For these financial instruments, we have elected to offset our derivative asset and liability positions, as well as cash collateral received or pledged, when we have met the netting requirements. We did not have any offsetting liabilities related to securities purchased under agreements to resell at June 30, 2013 and December 31, 2012.

The net exposure for these financial instruments can change on a daily basis; therefore, there may be a delay between the time this exposure change is identified and additional collateral is requested, and the time when this collateral is received or pledged. Likewise, there may be a delay for excess collateral to be returned. For derivative instruments that meet the netting requirements, any excess cash collateral received or pledged is recognized as a derivative liability or derivative asset. Additional information regarding these agreements is provided in Note 9 - Derivatives and Hedging Activities. Based on the fair value of the related collateral held, the securities purchased under agreements to resell were fully collateralized for the periods presented.

We offer our members certain Advances that provide them the right, at predetermined future dates, to prepay the Advance prior to maturity without incurring prepayment or termination fees. In exchange for receiving this right, a member typically pays a higher fixed rate for the Advance relative to a non-callable, fixed-rate Advance with an equivalent maturity or pays a higher spread on an adjustable rate Advance relative to a non-callable variable rate Advance with an equivalent maturity. If the call option is exercised, replacement funding may be available. Borrowers typically exercise their call options for fixed-rate Advances when interest rates decline or for adjustable-rate Advances when spreads change. At June 30, 2013 and December 31, 2012, we had such Advances outstanding of $3.5 billion and $3.7 billion, respectively. All other Advances may only be prepaid by paying a fee (prepayment fee) that is sufficient to make us financially indifferent to the prepayment of the Advance.

We offer putable and convertible Advances. Under the terms of a putable Advance, we retain the right to extinguish or put the fixed-rate Advance to the member on predetermined future dates, and offer, subject to certain conditions, replacement funding at prevailing market rates. At June 30, 2013 and December 31, 2012, we had putable Advances outstanding totaling $257,000 and $351,500, respectively. Under the terms of a convertible Advance, we may convert an Advance from one interest payment term structure to another. We had no convertible Advances outstanding at June 30, 2013 or December 31, 2012.

The following table presents Advances by the earlier of the year of contractual maturity or the next call date and next put date:

	Year of Contractual Maturity or Next Call Date				Year of Contractual Maturity or Next Put Date

Thereafter	1,629,500		2,204,790		3,512,865		3,985,200
Total Advances, par value	$	18,657,852	$	17,382,219	$	18,657,852	$	17,382,219

Prepayment Fees.When a borrower prepays an Advance, future income will be lower if the principal portion of the prepaid Advance is reinvested in lower-yielding assets that continue to be funded by higher-costing debt. To protect against this risk, we generally charge a prepayment fee. Advance prepayment fees, excluding any associated hedging basis adjustments, at the time of the prepayment were $25,193 and $30,841 for the three and six months ended June 30, 2013 compared to $6,778 and $7,670 for the three and six months ended June 30, 2012, respectively.

In cases in which we fund a new Advance concurrent with or within a short period of time before or after the prepayment of an existing Advance and the Advance meets the accounting criteria to qualify as a modification of the prepaid Advance, any prepayment fee, net of hedging basis adjustments, is deferred, recorded in the basis of the modified Advance, and amortized using a level-yield methodology over the life of the modified Advance, or as an adjustment to the interest coupon accrual of the modified Advance. For the three and six months ended June 30, 2013, we deferred $4,704 and $11,935, respectively, of these gross Advance prepayment fees, compared to $6,092 and $26,891, respectively, for the three and six months ended June 30, 2012.

Credit Risk Exposure and Security Terms. At June 30, 2013 and December 31, 2012, we had a total of $8.5 billion and $8.4 billion, respectively, of Advances outstanding, at par, to single borrowers with balances that were greater than or equal to $1.0 billion. These Advances, representing 46% and 48%, respectively, of total Advances at par outstanding on those dates, were made to four and five borrowers, respectively. At June 30, 2013 and December 31, 2012, we held $15.5 billion and $17.9 billion, respectively, of UPB of collateral to cover the Advances to these borrowers.

See Note 8 - Allowance for Credit Lossesfor information related to credit risk on Advances and allowance methodology for credit losses.

Schedule of Realized Gain (Loss) [Table Text Block]

The following table presents the proceeds, previously recognized OTTI credit losses including accretion, and gross realized gains and losses related to the sale of six OTTI AFS securities, only one of which was in an unrealized loss position. In the first quarter of 2013, we recorded an OTTI credit charge for this security, representing the entire difference between our amortized cost basis and its estimated fair value, which resulted in no gross realized losses related to the sale. We compute gains and losses on sales of investment securities using the specific identification method.

Other Than Temporary Impairments Analysis [Abstract]

Other-Than-Temporary-Impairment Analysis

Note 5 - Other-Than-Temporary Impairment Analysis

OTTI Evaluation Process and Results - Private-label RMBS and ABS. We evaluate our individual AFS and HTM securities that have been previously OTTI or are in an unrealized loss position for OTTI on a quarterly basis. As part of our evaluation, we consider whether we intend to sell each security and whether it is more likely than not that we will be required to sell the security before its anticipated recovery.

If either of these conditions is met, we recognize an OTTI loss in earnings equal to the entire difference between the debt security's amortized cost and its estimated fair value as of the Statement of Condition date. For the six months ended June 30, 2013, we recorded an OTTI credit charge of $1,924, representing the entire difference between our amortized cost basis and its estimated fair value, on one security for which we changed our previous intention to hold until recovery of its amortized cost. We did not have any such change in intent during the three months ended June 30,2013 or the three and six months ended June 30, 2012.

For those securities that meet neither of these conditions, we perform a cash flow analysis to determine whether we expect to recover the entire amortized cost of each security as described in Note 6 - Other-Than-Temporary Impairment Analysis of our 2012 Form 10-K. As a result of our analysis, we recognized additional OTTI credit losses of $0 and $292 for the three months ended June 30,2013 and 2012, respectively, and $0 and $3,580 during the six months ended June 30, 2013 and 2012, respectively. We determined that the unrealized losses on the remaining private-label RMBS and ABS were temporary as we expect to recover the entire amortized cost.

The following table presents a rollforward of the amounts related to credit losses recognized in earnings. The rollforward excludes accretion of credit losses for securities that have not experienced a significant increase in cash flows.

	Three Months Ended						Six Months Ended

The following table presents the June 30, 2013 classification and balances of OTTI securities impaired prior to June 30, 2013 (i.e., life to date) but not necessarily as of June 30, 2013. Securities are classified based on the originator's classification at the time of origination or based on the classification by the NRSROs upon issuance. Because there is no universally accepted definition of prime, Alt-A or subprime underwriting standards, such classifications are subjective.

OTTI Evaluation Process and Results - All Other AFS and HTM Securities.

Other U.S. and GSE Obligations and TVA Debentures. For other U.S. obligations, GSE obligations, and TVA debentures, we determined that 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 based on current expectations. As a result, we have determined that, as of June 30, 2013, all of the gross unrealized losses are temporary.

Allowance for Credit Losses

Allowance for Credit Losses [Abstract]

Allowance for Credit Losses

Note 8 - Allowance for Credit Losses

We have established an allowance methodology for each of our portfolio segments: credit products (Advances, letters of credit, and other extensions of credit to members); term securities purchased under agreements to resell; term federal funds sold; government-guaranteed or insured Mortgage Loans Held for Portfolio; and conventional Mortgage Loans Held for Portfolio. A description of the allowance methodologies related to our portfolio segments is disclosed in Note 9 - Allowance for Credit Losses in our 2012 Form 10-K.

Credit Products. Using a risk-based approach, we consider the amount and quality of the collateral pledged and the borrower's financial condition to be indicators of credit quality on the borrower's credit products. At June 30, 2013 and December 31, 2012, we had rights to collateral on a member-by-member basis with an estimated value in excess of our outstanding extensions of credit.

At June 30, 2013 and December 31, 2012, we did not have any credit products that were past due, on non-accrual status, or considered impaired.

Based upon the collateral held as security, our credit extension and collateral policies, our credit analysis and the repayment history on credit products, we have not recorded any allowance for credit losses on credit products. At June 30, 2013 and December 31, 2012, no liability to reflect an allowance for credit losses for off-balance sheet credit exposures was recorded. For additional information about off-balance sheet credit exposure, see Note 17 - Commitments and Contingencies.

MortgageLoans.

Credit Enhancements.

MPP Credit Enhancements. Our allowance for loan losses considers the credit enhancements associated with conventional mortgage loans under the MPP, which includes the original program and MPP Advantage. Any estimated losses that would be recovered from the credit enhancements are not reserved for as part of our allowance for loan losses. However, as part of the estimate of the recoverable credit enhancements, we evaluate the recovery and collectability related to our PMI/SMI policies. As a result of our evaluation, we reduced our estimates of recovery associated with the expected amount of our claims for all providers of these policies and established an allowance for unrecoverable PMI/SMI at June 30, 2013 and December 31, 2012 of $1,941 and $6,067, respectively, as a component of the allowance for MPP loan losses. This decrease in the allowance for unrecoverable PMI/SMI substantially comprised the reduction in our allowance for credit losses from December 31, 2012 to June 30, 2013.

The credit enhancements are applied to the estimated losses after any remaining borrower's equity in the following order: any applicable PMI up to coverage limits, any available funds remaining in the LRA up to each master commitment contract's allocated share, and any SMI coverage (not applicable to the MPP Advantage) up to the policy limits. Since we would bear any remaining loss, an estimate of the remaining loss is included in our allowance for loan losses.

The following table presents the impact of credit enhancements on the allowance:

MPP Credit Waterfall	June 30, 2013			December 31, 2012
Estimated losses remaining after borrower's equity, before credit enhancements	$	44,258		$	51,465
Portion of estimated losses recoverable from PMI	(5,543		)	(6,494		)
Portion of estimated losses recoverable from LRA	(6,846		)	(7,750		)
Portion of estimated losses recoverable from SMI	(28,810		)	(33,438		)
Allowance for unrecoverable PMI/SMI	1,941			6,067
Allowance for MPP loan losses	$	5,000		$	9,850

The following table presents the activity in the LRA:

Distributions	(541		)	(523		)
Balance of LRA, end of period	$	40,091		$	26,335

MPF Credit Enhancements. Our gross and net CE Fees paid to PFIs under the MPF program were $71 and $0 for the three months ended June 30,2013 and 2012, respectively, and $117 and $0 for the six months ended June 30, 2013 and 2012, respectively. We have had no performance-based CE Fees withheld or recovered from PFIs in 2013 or 2012.

If losses occur in a master commitment, these losses will either be: (i) recovered through the withholding of future performance-based CE Fees from the PFI or (ii) absorbed by us in the FLA. As of June 30, 2013 and December 31, 2012, our exposure under the FLA was $2,784 and $1,157, respectively, with CE Obligations available to cover losses in excess of the FLA totaling $21,320 and $8,607, respectively. Any estimated losses that would be absorbed by the CE Obligation are not reserved for as part of our allowance for loan losses. Accordingly, the calculated allowance was reduced by $151 and $67 as of June 30, 2013 and December 31, 2012, respectively, for the amount in excess of the FLA to be covered by PFIs’ CE Obligations. The resulting allowance for MPF loan losses at June 30, 2013 and December 31, 2012 was $500 and $150, respectively.

Allowance for Loan Losses on Mortgage Loans. The tables below present a rollforward of our allowance for loan losses on mortgage loans, the allowance for loan losses by impairment methodology, and the recorded investment in mortgage loans by impairment methodology. The recorded investment in a loan is the UPB of the loan, adjusted for accrued interest, net of 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 write-downs. The recorded investment is not net of any valuation allowance.

⁽¹⁾  The recorded investment in our MPP conventional loans individually evaluated for impairment excludes potential claims by servicers as of June 30, 2013 and December 31, 2012 for any losses resulting from past or future liquidations of the underlying properties on $15,340 and $15,665, respectively, of principal that was previously paid in full by the servicers. However, the MPP conventional loan allowance for loan losses includes $1,002 and $968 for these potential claims as of June 30, 2013 and December 31, 2012, respectively.

⁽¹⁾  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.

⁽²⁾  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 amounts that were previously paid in full by the servicers on conventional loans that are pending resolution of potential loss claims. Many FHA loans are repurchased by the servicers when they reach 90 days or more delinquent status, similar to the rules for servicers of Ginnie Mae MBS, resulting in the lower serious delinquency rate for FHA loans.

⁽³⁾  Although our past due scheduled/scheduled MPP loans are classified as loans past due 90 days or more based on the mortgagor's payment status, we do not consider these loans to be non-accrual.

Troubled Debt Restructurings. There were no MPF troubled debt restructurings at June 30, 2013 or December 31, 2012.

The table below presents the recorded investment of the performing and non-performing MPP troubled debt restructurings.

	June 30, 2013						December 31, 2012

During the three and six months ended June 30, 2013 and 2012, certain conventional MPP loans classified as troubled debt restructurings within the previous 12 months experienced a payment default. A borrower is considered to have defaulted on a troubled debt restructuring if the borrower's contractually due principal or interest is 60 days or more past due at any time during the period presented. The recorded investment of certain conventional MPP loans classified as troubled debt restructurings within the previous 12 months that experienced a payment default was $420 and $1,041 for the three and six months ended June 30, 2013, respectively, compared to $2,157 and $2,829 for the three and six months ended June 30, 2012, respectively. For purposes of this disclosure, only the initial default was included; however, a loan can experience another payment default in a subsequent period.

A loan considered to be a troubled debt restructuring is individually evaluated for impairment when determining its related allowance for loan loss. The tables below present the impaired conventional loans individually evaluated for impairment as of June 30, 2013 and December 31, 2012. The first table presents the recorded investment, UPB and related allowance associated with these loans while the next tables present the average recorded investment of individually impaired loans and related interest income recognized.

⁽¹⁾  Amortized cost includes adjustments made to the cost basis of an investment for accretion, amortization, collection of principal, and, if applicable, OTTI recognized in earnings (credit losses).

⁽²⁾  Carrying value of HTM securities represents amortized cost after adjustment for non-credit OTTI recognized in AOCI.

⁽³⁾  Gross unrecognized holding gains (losses) represents the difference between estimated fair value and carrying value.

Premiums and Discounts. At June 30, 2013 and December 31, 2012, the amortized cost of our MBS and ABS HTM securities included unamortized purchase premiums and discounts, OTTI credit losses, and OTTI-related accretion adjustments resulting in net premiums of $47,458 and $51,784, respectively.

Unrealized Loss Positions. The following table presents impaired HTM securities (i.e., in an unrealized loss position), aggregated by major security type and length of time that individual securities have been in a continuous unrealized loss position. None of our non-MBS were in an unrealized loss position at June 30, 2013 or December 31, 2012.

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

Debt Disclosure [Abstract]

Consolidated Obligations

Note 11 - Consolidated Obligations

As provided by the Bank Act and applicable regulations, Consolidated Obligations are backed only by the financial resources of all 12 FHLBanks. Although we are primarily liable for our portion of Consolidated Obligations (i.e., those issued on our behalf), we are also jointly and severally liable with the other 11 FHLBanks for the payment of the principal and interest on all Consolidated Obligations of each of the FHLBanks. No FHLBank has ever been asked or required to repay the principal or interest on any Consolidated Obligation on behalf of another FHLBank, and we do not believe that it is probable that we will be asked to do so. The par values of the 12 FHLBanks' outstanding Consolidated Obligations, including Consolidated Obligations held by other FHLBanks, totaled $704.5 billion and $687.9 billion at June 30, 2013 and December 31, 2012, respectively.

Capital [Abstract]

Capital

Note 13 - Capital

We are subject to capital requirements under our capital plan and the Finance Agency rules and regulations as disclosed in Note 15 - Capital in our 2012 Form 10-K. As presented in the following table, we were in compliance with the Finance Agency's capital requirements at June 30, 2013 and December 31, 2012. For regulatory purposes, AOCI is not considered capital; MRCS, however, is considered capital.

	June 30, 2013						December 31, 2012
Regulatory Capital Requirements	Required			Actual			Required			Actual
Risk-based capital	$	754,866		$	2,600,030		$	636,022		$	2,676,616
Regulatory permanent capital-to-asset ratio	4.00		%	6.51		%	4.00		%	6.49		%
Regulatory permanent capital	$	1,596,604		$	2,600,030		$	1,649,105		$	2,676,616
Leverage ratio	5.00		%	9.77		%	5.00		%	9.74		%
Leverage capital	$	1,995,755		$	3,900,045		$	2,061,382		$	4,014,924

Mandatorily Redeemable Capital Stock.At June 30, 2013 and December 31, 2012, we had $255,720 and $450,716, respectively, in capital stock subject to mandatory redemption, which is classified as a liability in the Statement of Condition.

The following table presents the activity in MRCS:

	Three Months Ended June 30,						Six Months Ended June 30,
MRCS Activity	2013			2012			2013			2012
Balance at beginning of period	$	160,499		$	457,425		$	450,716		$	453,885
Additions due to change in membership status	95,441			—			95,441			3,513

Balance at end of period	$	255,720		$	450,898		$	255,720		$	450,898

There were 17 and 27 former members holding MRCS at June 30, 2013 and December 31, 2012, respectively, which include zero and eight institutions, respectively, that were members at the time of their acquisition by the FDIC in its capacity as receiver. During the three months ended June 30, 2013, we repurchased MRCS of $355 pursuant to our statutory and contractual lien on excess capital stock owned by a former member in order to enforce our contractual rights under our MPP and our Advances, Pledge and Security Agreement regarding mortgage loans sold to us. During the six months ended June 30, 2013, we repurchased $250,000 par value of excess stock held as of December 31, 2012 by shareholders that are former members (or their successors-in-interest). We redeemed an additional $40,574 of excess stock held by members or former members because the stock had reached the end of its five-year redemption period.

The following table presents the amount of MRCS by contractual year of redemption. The year of redemption in the table is the later of the end of the five-year redemption period, or the maturity date of the activity to which the stock is related, if the stock represents the activity-based stock purchase requirement of a non-member (a former member that withdrew from membership, merged into a non-member or was otherwise acquired by a non-member).

Contractual Year of Redemption	June 30, 2013		December 31, 2012
Year 1	$	18,872	$	268,512
Year 2	128,659		144,644
Year 3	502		20,511
Year 4	12,246		13,536
Year 5	95,441		3,513
Total MRCS	$	255,720	$	450,716

The following table presents distributions on MRCS:

	Three Months Ended June 30,				Six Months Ended June 30,
MRCS Distributions	2013		2012		2013		2012
Recorded as Interest Expense	$	2,080	$	3,326	$	4,488	$	7,237
Recorded as distributions from Retained Earnings	137		—		137		27
Total	$	2,217	$	3,326	$	4,625	$	7,264

Excess Capital Stock. Excess capital stock is defined as the amount of stock held by a member or former member in excess of that institution's minimum stock requirement. Finance Agency rules limit the ability of an FHLBank to create member excess stock under certain circumstances, including if excess stock exceeds 1% of Total Assets or if the issuance of excess stock would cause excess stock to exceed 1% of Total Assets. Our excess stock totaled $691,578 at June 30, 2013, which equaled approximately 1.7% of our Total Assets. Therefore, we are currently not permitted to issue new excess stock to members or distribute stock dividends.

[1] 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.

[2] 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 amounts that were previously paid in full by the servicers on conventional loans that are pending resolution of potential loss claims. Many FHA loans are repurchased by the servicers when they reach 90 days or more delinquent status, similar to the rules for servicers of Ginnie Mae MBS, resulting in the lower serious delinquency rate for FHA loans.

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

[1] The recorded investment in our MPP conventional loans individually evaluated for impairment excludes potential claims by servicers as of June 30, 2013 and December 31, 2012 for any losses resulting from past or future liquidations of the underlying properties on $15,340 and $15,665, respectively, of principal that was previously paid in full by the servicers. However, the MPP conventional loan allowance for loan losses includes $1,002 and $968 for these potential claims as of June 30, 2013 and December 31, 2012, respectively.
