Executive Summary

Overview. The Bank's financial condition and results of operations are influenced by global and national economies, local economies within its three-state district, and the conditions in the financial, housing and credit markets; all of which impact the interest rate environment.

The interest rate environment significantly impacts the Bank's profitability. Net interest income is affected by several external factors, including market interest rate levels and volatility, credit spreads and the general state of the economy. To manage interest rate risk, the Bank executes interest-rate exchange agreements in which 1-month or 3-month LIBOR is received (advances) or paid (debt). Short-term interest rates also directly affect the Bank's earnings on invested capital. Finally, the Bank's mortgage-related assets make it sensitive to changes in mortgage rates. The Bank earns relatively narrow spreads between yields on assets (particularly advances, its largest asset) and the rates paid on corresponding liabilities.

The Bank's earnings are affected not only by rising or falling interest rates but also by the particular path and volatility of changes in market interest rates and the prevailing shape of the yield curve. The flattening of the yield curve tends to compress the Bank's net interest margin, while steepening of the curve offers better opportunities to purchase assets with wider net interest spreads. The performance of the Bank's mortgage asset portfolios is particularly affected by shifts in the 10-year maturity range of the yield curve, which is the point that heavily influences mortgage rates and potential refinancings. Yield curve shape can also influence the pace at which borrowers refinance or prepay their existing loans, as borrowers may select shorter-duration mortgage products.

Results of Operations. The Bank's net income for the second quarter of 2018 was $91.6 million compared to $88.0 million for the second quarter of 2017. This $3.6 million increase was driven primarily by higher net interest income, partially offset by higher total other expense. Net interest income was $117.1 million for the second quarter of 2018, compared to $110.4

million in the second quarter of 2017. Interest income and expense were impacted by the rising interest rate environment. The net interest margin was 49 basis points and 47 basis points for the second quarter of 2018 and 2017, respectively.

For the six months ended June 30, 2018, net income was $170.5 million compared to $174.8 million for the same prior-year period, a decrease of $4.3 million. The decrease was primarily due to a decrease in total other noninterest income, partially offset by higher net interest income. Noninterest income was $9.3 million in the first six months of 2018, compared to $19.7 million in the same period of 2017. Net interest income was $226.7 million for the first six months of 2018, an increase of $8.0 million compared to $218.7 million in the same period in 2017 and reflected the rising interest rate environment during the first half of 2018. The net interest margin was 48 and 46 basis points for the first six months of 2018 and 2017, respectively.

Financial Condition. Advances. Advances totaled $76.3 billion at June 30, 2018, an increase of $2.0 billion compared to $74.3 billion at December 31, 2017. It is not uncommon for the Bank to experience variances in the overall advance portfolio driven primarily by changes in member needs. While the advance portfolio increased compared to December 31, 2017, the term of advances decreased slightly. At June 30, 2018, approximately 57% of the par value of advances in the portfolio had a remaining maturity of more than one year, compared to 58% at December 31, 2017.

The ability to grow and/or maintain the advance portfolio is affected by, among other things, the following: (1) the liquidity demands of the Bank's borrowers; (2) the composition of the Bank's membership; (3) members' regulatory requirements; (4) current and future credit market conditions; (5) housing market trends; (6) the shape of the yield curve and (7) advance pricing.

Liquidity. At June 30, 2018, the Bank held $8.8 billion of liquid assets compared to $10.2 billion at December 31, 2017. The Bank maintains its liquidity to meet member borrowing needs and is comprised of cash, interest-bearing deposits, Federal funds sold, securities purchased under agreements to resell, and U.S. Treasury and Agency securities classified as trading investments.

Available-for-Sale (AFS) and Held-to-Maturity (HTM) Investments. The Bank also maintains investments classified as AFS and HTM to enhance earnings. At June 30, 2018, the Bank held $12.1 billion in its investment portfolio compared to $10.9 billion at December 31, 2017. The change in these portfolios was primarily due to the Bank using cash to purchase certificates of deposit.

Consolidated Obligations. The Bank's consolidated obligations totaled $95.7 billion at June 30, 2018, an increase of $2.0 billion from December 31, 2017. At June 30, 2018, bonds represented 72% of the Bank's consolidated obligations, compared with 60% at December 31, 2017. Discount notes represented 28% of the Bank's consolidated obligations at June 30, 2018 compared with 40% at year-end 2017. The overall increase in consolidated obligations is largely consistent with the changes in advances and total assets.

Capital Position and Regulatory Requirements. Total capital at June 30, 2018 was $5.3 billion, compared to $4.9 billion at December 31, 2017. Total retained earnings at June 30, 2018 were $1,215.7 million, up $57.8 million from $1,157.9 million at year-end 2017, reflecting the Bank's net income for the first half of 2018, which was partially offset by dividends paid. Accumulated other comprehensive income (AOCI) was $100.7 million at June 30, 2018, a decrease of $10.2 million from December 31, 2017. This decrease was primarily due to changes in the fair values of securities within the AFS portfolio.

In February, April and July 2018, the Bank paid quarterly dividends of 6.75% annualized on activity stock and 3.5% annualized on membership stock. These dividends were based on stockholders' average balances for the fourth quarter of 2017 (February dividend), the first quarter of 2018 (April dividend), and the second quarter of 2018 (July dividend).

The Bank met all of its capital requirements as of June 30, 2018, and in the Federal Housing Finance Agency's (Finance Agency) most recent determination, as of March 31 2018, the Bank was deemed "adequately capitalized."

Earnings Performance

The following is Management's Discussion and Analysis of the Bank's earnings performance for the three and six months ended June 30, 2018 and 2017, which should be read in conjunction with the Bank's unaudited interim financial statements included in this Form 10-Q as well as the audited financial statements included in Item 8. Financial Statements and Supplementary Financial Data in the Bank's 2017 Form 10-K.

Summary of Financial Results

Net Income and Return on Average Equity. The Bank’s net income totaled $91.6 million for the second quarter of 2018, compared to $88.0 million for the second quarter of 2017. This $3.6 million increase was driven primarily by higher net interest income, partially offset by higher total other expense. Net interest income was $117.1 million for the second quarter of 2018, compared to $110.4 million in the second quarter of 2017. Interest income and expense were impacted by the rising interest rate environment. Total other expense increased $2.8 million in the second quarter of 2018, compared to the second quarter of 2017, primarily due to higher compensation and benefits. The Bank's return on average equity for the second quarter of 2018 was 7.41% compared to 7.49% for the second quarter of 2017.

For the six months ended June 30, 2018, net income was $170.5 million compared to $174.8 million for the same prior-year period, a decrease of $4.3 million. The decrease was primarily due to a decrease in total other noninterest income, partially offset by higher net interest income. Noninterest income was $9.3 million in the first six months of 2018, compared to $19.7 million in the same period of 2017. This $10.4 million decrease was primarily driven by net losses on trading securities of $11.4 million in the first six months of 2018, compared to net gains of $7.6 million in the same period in 2017, partially offset by an increase in net gains on derivatives and hedging activities of $8.1 million. Net interest income was $226.7 million for the first six months of 2018, an increase of $8.0 million compared to $218.7 million in the same period in 2017 and reflected the rising interest rate environment during the first half of 2018. The Bank's return on average equity for the first six months of 2018 was 7.02% compared to 7.50% for the same prior year period.

Net Interest Income

The following table summarizes the yields and rates paid on interest-earning assets and interest-bearing liabilities, respectively, the average balance for each of the primary balance sheet classifications, and the net interest margin for the three and six months ended June 30, 2018 and 2017.

Notes:

⁽¹⁾ The average balance of Federal funds sold and securities purchased under agreements to resell and the related interest income and average yield calculations may include loans to other FHLBanks.

⁽²⁾ Average balances of deposits (assets and liabilities) include cash collateral received from/paid to counterparties which is reflected in the Statements of Condition as derivative assets/liabilities.

⁽³⁾ Investment securities include trading, AFS and HTM securities. The average balances of AFS and HTM are reflected at amortized cost; therefore, the resulting yields do not give effect to changes in fair value or the noncredit component of recognized OTTI reflected in AOCI.

⁽⁴⁾ Average balances reflect noninterest-earning hedge accounting adjustments of $(253.3) million and $(17.6) million in 2018 and 2017, respectively.

⁽⁵⁾ Nonaccrual mortgage loans are included in average balances in determining the average rate.

⁽⁶⁾The allowance for credit losses and the noncredit portion of OTTI losses on investment securities is reflected in other assets for purposes of the average balance sheet presentation.

⁽⁷⁾ Average balances reflect noninterest-bearing hedge accounting adjustments of $(229.9) million and $(89.0) million in 2018 and 2017, respectively.

Net interest income for the second quarter of 2018 increased $6.7 million from the same prior year period due to an increase in interest income, partially offset by higher interest expense. Interest-earning assets increased 0.7% primarily due to increased purchases of mortgage loans held for portfolio and higher demand for advances, partially offset by decreased purchases of Federal funds sold and securities purchased under agreements to resell. The rate earned on interest-earning assets increased 84 basis points primarily due to a higher yield on advances. Interest income increased across all categories. Interest

income on advances increased due to an increase in yield. Interest income on Federal funds sold and securities purchased under agreements to resell increased due to an increase in yield. Interest income on mortgage loans held for portfolio increased due to increased volume, which more than offset the run-off of higher-yielding assets that have been replaced with lower-yielding assets. The rate paid on interest-bearing liabilities increased 87 basis points due to higher funding costs on consolidated obligation bonds and discount notes. The impact of noninterest-bearing funds increased 5 basis points due to higher interest rates.

Notes:

⁽⁴⁾ Average balances reflect noninterest-earning hedge accounting adjustments of $(216.7) million and $(22.4) million in 2018 and 2017, respectively.

⁽⁵⁾ Nonaccrual mortgage loans are included in average balances in determining the average rate.

⁽⁶⁾The allowance for credit losses and the noncredit portion of OTTI losses on investment securities is reflected in other assets for purposes of the average balance sheet presentation.

⁽⁷⁾ Average balances reflect noninterest-bearing hedge accounting adjustments of $(208.8) million and $(92.8) million in 2018 and 2017, respectively.

Net interest income for the first six months of 2018 increased $8.0 million from the same prior year period due to an increase in interest income, partially offset by higher interest expense. Interest-earning assets were relatively unchanged as increased purchases of Federal funds sold and securities purchased under agreements to resell and mortgage loans held for portfolio were offset by lower demand for advances and decreased purchases of investment securities. The rate earned on interest-bearing assets increased 74 basis points primarily due to a higher yield on advances. Interest income increased across all categories. The increase was primarily driven by increase in interest rates. The rate paid on interest-bearing liabilities

increased 77 basis points due to higher funding costs on consolidated obligation bonds and discount notes. The impact of noninterest-bearing funds increased 5 basis points due to higher interest rates.

Rate/Volume Analysis. Changes in both volume and interest rates influence changes in net interest income and net interest margin. The following table summarizes changes in interest income and interest expense between the three and six months ended June 30, 2018 and 2017.

Interest income and interest expense increased in both the quarter-over-quarter and year-over-year comparisons. Higher rates drove the increases in both interest income and expense while volumes were steady. The rate increase was primarily due to an increase in market interest rates as the Federal funds target rate increased five times between January 2017 and June 2018.

Interest expense on the average consolidated obligations portfolio increased in both comparisons. Rates paid on both discount notes and bonds rose due to the rise in market interest rates. In both comparisons, a decrease in average discount note balances was partially offset by an increase in average bond balances. A portion of the bond portfolio is currently swapped to 3-month LIBOR; therefore, as the LIBOR rate (decreases) increases, interest expense on swapped bonds, including the impact of swaps, (decreases) increases. See details regarding the impact of swaps on the rates paid in the “Interest Income Derivatives Effects” discussion below.

The following table presents the average par balances of the Bank's advance portfolio for the three and six months ended June 30, 2018 and 2017. These balances do not reflect any hedge accounting adjustments.

Note:

⁽¹⁾Impact of Derivatives includes net interest settlements, amortization of basis adjustments resulting from previously terminated hedging relationships and the amortization of the market value of mortgage purchase commitments classified as derivatives at the time the commitment settled.

The use of derivatives reduced net interest income and net interest spread for the three and six months ended June 30, 2018 and 2017. The variances in the advances and consolidated obligation derivative impacts from period to period are driven by the change in the average LIBOR-based variable rate, the timing of interest rate resets and the average hedged portfolio balances outstanding during any given period.

The Bank uses derivatives to hedge the fair market value changes attributable to the change in the LIBOR benchmark interest rate. The Bank generally uses interest rate swaps to hedge a portion of advances and consolidated obligations, which convert the interest rates on those instruments from a fixed rate to a LIBOR-based variable rate. The purpose of this strategy is

to protect the interest rate spread. Using derivatives to convert interest rates from fixed to variable can increase or decrease net interest income.

The Bank uses many different funding and hedging strategies. These strategies involve closely match-funding bullet advances with bullet debt. This is designed in part to avoid the use of derivatives where prudent and reduce the Bank's reliance on short-term funding.

Provision (Benefit) for Credit Losses. The provision (benefit) for credit losses on mortgage loans held for portfolio and Banking on Business (BOB) loans was $0.4 million for the second quarter of 2018 and was $(0.1) million for the same period in 2017. For the six months ended June 30, 2018 and 2017, the provision (benefit) for credit losses on mortgage loans held for portfolio and BOB loans was $2.8 million and $(0.1) million, respectively. The six month increase was primarily due to a non-recurring adjustment to the MPF Plus product.

The change in the Bank's total other noninterest income for the second quarter of 2018 compared to the same prior year period was due primarily to net gains on derivatives and hedging activities partially offset by net losses on trading securities. The change in the Bank's total other noninterest income for the first half of 2018 compared to the same prior year period was due primarily to net losses on trading securities partially offset by an increase in net gains on derivatives and hedging activities. The net losses on trading securities reflects the impact of fair market value changes in Agency and U.S. Treasury investments held in the Bank's trading portfolio. The activity related to derivatives and hedging is discussed in more detail below.

Derivatives and Hedging Activities. The Bank enters into interest rate swaps, caps, floors and swaption agreements, referred to collectively as interest rate exchange agreements and more broadly as derivatives transactions. The Bank enters into derivatives transactions to offset all or portions of the financial risk exposures inherent in its member lending, investment and funding activities. All derivatives are recorded on the balance sheet at fair value. Changes in derivatives' fair values are recorded in the Statements of Income.

The Bank's hedging strategies consist of fair value accounting hedges and economic hedges. Fair value hedges are discussed in more detail below. Economic hedges address specific risks inherent in the Bank's balance sheet, but either they do not qualify for hedge accounting or the Bank does not elect to apply hedge accounting. As a result, income recognition on the derivatives in economic hedges may vary considerably compared to the timing of income recognition on the underlying asset or liability. The Bank does not enter into derivatives for speculative purposes nor does it have any cash flow hedges.

Regardless of the hedge strategy employed, the Bank's predominant hedging instrument is an interest rate swap. At the time of inception, the fair market value of an interest rate swap generally equals or is close to zero. Notwithstanding the exchange of interest payments made during the life of the swap, which are recorded as either interest income/expense or as a gain (loss) on derivatives, depending upon the accounting classification of the hedging instrument, the fair value of an interest rate swap returns to zero at the end of its contractual term. Therefore, although the fair value of an interest rate swap is likely to change over the course of its full term, upon maturity any unrealized gains and losses generally net to zero.

The following tables detail the net effect of derivatives and hedging activities for the three and six months ended June 30, 2018 and 2017.

Fair value hedges. The Bank uses interest rate swaps to hedge a large portion of its fixed-rate advances and consolidated obligations and a small portion of its fixed rate investment securities. The interest rate swaps convert these fixed-rate instruments to a variable-rate (i.e., LIBOR). Most of these hedge relationships are subject to fair value hedge accounting treatment. Fair value hedge ineffectiveness represents the difference between the change in the fair value of the derivative and the change in the fair value of the underlying asset/liability hedged. Fair value hedge ineffectiveness is generated by movement in the benchmark interest rate being hedged and by other structural characteristics of the transaction involved. For example, the presence of an upfront fee associated with a structured debt hedge will introduce valuation differences between the hedge and hedged item that will fluctuate over time. During the second quarter of 2018, the Bank recorded net losses of $(1.7) million compared to net losses of $(0.4) million for the second quarter of 2017. For the six months ended June 30, 2018 and 2017, the Bank recorded net losses of $(0.5) million and net gains of $0.2 million, respectively. The total notional amount increased to $35.9 billion at June 30, 2018, up from $30.0 billion at December 31, 2017.

Derivatives not receiving hedge accounting. For derivatives not receiving hedge accounting, also referred to as economic hedges, the Bank includes the net interest settlements and the fair value changes in the "Net gains (losses) on derivatives and hedging activities" financial statement line item. For economic hedges, the Bank recorded net gains of $6.6 million in second quarter of 2018 compared to net losses of $(4.1) million for the second quarter of 2017. For the six months ended June 30, 2018, the Bank recorded net gains of $9.9 million compared to net losses of $(0.4) million for the period ended June 30, 2017. The net gains for 2018 were driven by rising LIBOR rates and their impact on derivatives hedging the Bank's assets. The total notional amount of economic hedges, which includes mortgage delivery commitments, was $17.0 billion at June 30, 2018 and $14.8 billion at December 31, 2017. The increase in economic hedge notional from December 31, 2017 to June 30, 2018 was primarily due to new basis swaps executed in the first quarter of 2018 to hedge basis risk between 1-month and 3-month LIBOR.

Other Expense

The Bank's total other expenses increased $2.8 million to $22.5 million for the second quarter of 2018, compared to the same prior year period. For the first half of 2018 compared to the same prior year period, the Bank's total other expense decreased $0.5 million, to $43.7 million. The change in total other expenses was primarily driven by the Bank's voluntary contributions to its pension plan. The Bank made a $2.0 million contribution in the second quarter of 2018 and $3.0 million for the first half of 2018, compared to none during the second quarter of 2017 and $4.0 million in the first half of 2017.

Financial Condition

The following should be read in conjunction with the Bank's unaudited interim financial statements in this Form 10-Q and the audited financial statements in the Bank's 2017 Form 10-K.

Assets

Total assets were $101.8 billion at June 30, 2018, compared with $99.7 billion at December 31, 2017, a increase of $2.1 billion. The increase was primarily due to an increase in advances. Advances totaled $76.3 billion at June 30, 2018, a increase of $2.0 billion compared to $74.3 billion at December 31, 2017.

The Bank's core mission activities include the issuance of advances and acquiring member assets through the Mortgage Partnership Finance^® (MPF^®) program. The core mission asset ratio, defined as the ratio of par amount of advances and MPF loans relative to consolidated obligations using full year average balances, was 84.4% and 83.5% as of June 30, 2018 and December 31, 2017, respectively.

Advances. Advances (par) totaled $76.6 billion at June 30, 2018 compared to $74.4 billion at December 31, 2017. At June 30, 2018, the Bank had advances to 179 borrowing members, compared to 185 borrowing members at December 31, 2017. A significant amount of the advances continued to be generated from the Bank’s five largest borrowers, reflecting the asset concentration mix of the Bank’s membership base. Total advances outstanding to the Bank’s five largest borrowers decreased to 75.5% of total advances as of June 30, 2018, compared to 77.3% at December 31, 2017.

The following table provides information on advances at par by contractual maturity at June 30, 2018 and December 31, 2017.

As of June 30, 2018, total advances increased 3.0% compared with balances at December 31, 2017. It is not uncommon for the Bank to experience variances in the overall advance portfolio driven primarily by changes in member needs.

See the “Credit and Counterparty Risk - TCE and Collateral” discussion in the Risk Management section of this Item 2 for further information on collateral policies and practices and details regarding eligible collateral, including amounts and percentages of eligible collateral securing member advances as of June 30, 2018.

Mortgage Loans Held for Portfolio. Mortgage loans held for portfolio, net of allowance for credit losses, totaled $4.2 billion and $3.9 billion at June 30, 2018 and December 31, 2017 respectively.

The Bank places conventional mortgage loans that are 90 days or more delinquent on nonaccrual status. In addition, the Bank records cash payments received as a reduction of principal until the remaining principal amount due is expected to be collected and then as a recovery of any charge-off, if applicable, followed by the recording of interest income. However, government mortgage loans that are 90 days or more delinquent remain in accrual status due to government guarantees or insurance. The Bank has a loan modification program for participating financial institutions (PFIs) under the MPF program. The Bank considers loan modifications or Chapter 7 bankruptcies where the obligation is discharged under the MPF program to be troubled debt restructurings (TDRs), since some form of concession has been made by the Bank. Balances regarding the Bank’s loan products are summarized below.



(in millions)	June 30, 2018		December 31, 2017
Advances ⁽¹⁾	$	76,340.0	$	74,279.8
Mortgage loans held for portfolio, net ⁽²⁾	4,171.5		3,923.1
Nonaccrual mortgage loans ⁽³⁾	16.9		22.8
Mortgage loans 90 days or more delinquent and still accruing interest ⁽⁴⁾	3.4		4.8
BOB loans, net	16.2		14.1

Notes:

⁽¹⁾ There are no advances which are past due or on nonaccrual status.

⁽²⁾ All mortgage loans are fixed-rate. Balances are reflected net of the allowance for credit losses.

⁽³⁾ Nonaccrual mortgage loans are reported net of interest applied to principal and do not include performing TDRs.

⁽⁴⁾ Only government-insured or -guaranteed loans continue to accrue interest after becoming 90 days or more delinquent.

The performance of the mortgage loans in the Bank’s MPF Program has been relatively stable, and the MPF Original portfolio continues to outperform the market based on national delinquency statistics. As of June 30, 2018, the Bank’s seriously delinquent mortgage loans (90 days or more delinquent or in the process of foreclosure) represented 0.4% of the MPF Original portfolio and 2.3% of the MPF Plus portfolio compared with 0.6% and 2.6%, respectively, at December 31, 2017. The MPF 35 portfolio delinquency remains minimal at 0.01%, for both June 30, 2018 and December 31, 2017, as it is still relatively new.

Allowance for Credit Losses (ACL). The Bank has not incurred any losses on advances since its inception in 1932. Due to the collateral held as security and the repayment history for advances, management believes that an ACL for advances is not appropriate under GAAP. This assessment also includes letters of credit, which have the same collateral requirements as advances. For additional information, see discussion regarding collateral policies and standards on the advances portfolio in the Advance Products discussion in Item 1. Business in the Bank's 2017 Form 10-K.

The ACL on mortgage loans is based on the losses inherent in the Bank's mortgage loan portfolio after taking into consideration the credit enhancement (CE) structure of the MPF Program. The losses inherent in the portfolio are based on either an individual or collective assessment of the mortgage loans. The Bank purchases government-guaranteed and/or -insured and conventional fixed-rate residential mortgage loans. Because the credit risk on the government-guaranteed/insured loans is predominantly assumed by other entities, only conventional mortgage loans are evaluated for an ACL.

The Bank’s conventional mortgage loan portfolio is comprised of large groups of smaller-balance homogeneous loans made to borrowers of PFIs that are secured by residential real estate. A mortgage loan is considered impaired when it is probable that all contractual principal and interest payments will not be collected as scheduled based on current information and events. The Bank evaluates certain conventional mortgage loans for impairment individually and the related credit loss is charged-off against the reserve. However, if the estimated loss can be recovered through CE, a receivable is established, resulting in a net charge-off. The CE receivable is evaluated for collectibility, and a reserve, included as part of the allowance for credit losses, is established, if required.

The remainder of the portfolio's incurred loss is estimated using a collective assessment, which is based on probability of default and loss given default. Probability of default and loss given default are based on the prior 12-month historical performance of the Bank's mortgage loans. Probability of default is based on a migration analysis, and loss given default is based on realized losses incurred on the sale of mortgage loan collateral, including a factor that reduces estimated proceeds from primary mortgage insurance (PMI) given the credit deterioration experienced by those companies.

Mortgage loans are assessed by a third party's credit model at acquisition and a CE is calculated based on loan attributes and the Bank’s risk tolerance on its entire MPF portfolio. Credit losses on a mortgage loan may only be absorbed by the CE amount in the master commitment related to the loan. In addition, the CE structure of the MPF Program is designed such that initial losses on mortgage loans are incurred by the Bank up to an agreed upon amount, referred to as the first loss account (FLA). Additional eligible credit losses are covered by CEs provided by PFIs (available CE) until exhausted. Certain losses incurred by the Bank on MPF 35 and MPF Plus can be recaptured by withholding fees paid to the PFI for its retention of credit risk. All additional losses are incurred by the Bank.

The following table presents the impact of the CE structure on the ACL and the balance of the FLA and available CE at June 30, 2018 and December 31, 2017.



	MPF CE structure June 30, 2018				ACL June 30, 2018
(in millions)	FLA		Available CE		Estimate of Credit Loss		Charge - offs			Reduction to the ACL due to CE			ACL
MPF Original	$	5.3	$	76.4	$	5.8	$	(1.3	)	$	(3.9	)	$	0.6

	MPF CE structure December 31, 2017				ACL December 31, 2017
(in millions)	FLA		Available CE		Estimate of Credit Loss		Charge - offs			Reduction to the ACL due to CE			ACL
MPF Original	$	4.9	$	78.7	$	6.0	$	(1.1	)	$	(4.4	)	$	0.5
MPF 35	4.2		38.0		0.2		—			(0.2		)	—
MPF Plus	16.9		10.0		9.5		—			(4.0		)	5.5
Total	$	26.0	$	126.7	$	15.7	$	(1.1	)	$	(8.6	)	$	6.0

The ACL on mortgage loans increased $2.0 million during the first six months of 2018. The increase is primarily due to a non-recurring adjustment to the MPF Plus product. The ACL associated with MPF Original remained consistent, and the ACL associated with the MPF 35 program remained zero due to the nature of its credit structure and performance.

Investments. At June 30, 2018, the sum of the Bank's interest-bearing deposits, Federal funds sold and securities purchased under agreements to resell was $8.1 billion, an increase of approximately $1.7 billion from December 31, 2017. The Bank's strategy is to maintain its short-term liquidity position in part to be able to meet members' loan demand and regulatory liquidity requirements. Investment securities, including trading, AFS, and HTM securities, totaled $12.7 billion at June 30, 2018, compared to $11.3 billion at December 31, 2017. Details of the investment securities portfolio follow.

Liabilities and Capital

Deposits. The Bank offers demand, overnight and term deposits for members and qualifying nonmembers. Total deposits at June 30, 2018 increased to $551.1 million from $538.1 million at December 31, 2017.

Consolidated Obligations. Consolidated obligations consist of bonds and discount notes. The Bank's consolidated obligations totaled $95.7 billion at June 30, 2018, an increase of $2.0 billion from December 31, 2017. The increase in total consolidated obligations was mainly due to the advance balance increase in 2018.

At June 30, 2018, the Bank’s bonds outstanding increased to $68.7 billion compared to $57.5 billion at December 31, 2017. Conversely, discount notes outstanding at June 30, 2018 decreased to $27.0 billion from $36.2 billion at December 31, 2017. The shorter-term discount notes were issued near year-end 2017 to make additional liquidity available to members, if needed, and caused the shift in bonds compared to discount notes outstanding for the first half of 2018.

The Bank primarily uses noncallable bonds as a source of funding but also utilizes structured notes such as callable bonds. Unswapped callable bonds primarily fund the Bank’s mortgage portfolio while swapped callable bonds fund other floating rate assets. For additional information on the Bank's consolidated obligations, refer to Note 14 to the audited financial statements in Item 8. Financial Statements and Supplementary Financial Data of the Bank's 2017 Form 10-K.

Commitments and Off-Balance Sheet Items. As of June 30, 2018, the Bank was obligated to fund approximately $15.7 million in additional advances and BOB loans, $35.8 million of mortgage loans and $18.6 billion in outstanding standby letters of credit, and to issue $1.9 billion in consolidated obligations. The Bank does not consolidate any off-balance sheet special purpose entities or other off-balance sheet conduits.

Capital and Retained Earnings. The Finance Agency has issued regulatory guidance to the FHLBanks relating to capital management and retained earnings. The guidance directs each FHLBank to assess, at least annually, the adequacy of its retained earnings with consideration given to future possible financial and economic scenarios. The guidance also outlines the considerations that each FHLBank should undertake in assessing the adequacy of its retained earnings.

Management monitors capital adequacy, including the level of retained earnings, through the evaluation of market value of equity to par value of capital stock (MV/CS) as well as other risk metrics. Details regarding these metrics are discussed in the Risk Management portion of this Item 2.

Management has developed and adopted a framework for evaluating retained earnings adequacy, consistent with regulatory guidance and requirements. Retained earnings are intended to cover unexpected losses and protect members' par value of capital stock. The framework includes four risk elements that comprise the Bank's total retained earnings target: (1) market risk; (2) credit risk; (3) operational risk; and (4) accounting risk. The retained earnings target generated from this framework is sensitive to changes in the Bank's risk profile, whether favorable or unfavorable. The framework assists management in its overall analysis of the level of future dividends. The framework generated a retained earnings target of $564 million as of June 30, 2018. The Bank's retained earnings were $1,215.7 million at June 30, 2018.

Retained earnings increased $57.8 million to $1,215.7 million at June 30, 2018, compared to $1,157.9 million at December 31, 2017. The increase in retained earnings during the first six months of 2018 reflected net income that was

partially offset by $112.7 million of dividends paid. Total retained earnings at June 30, 2018 included unrestricted retained earnings of $899.1 million and restricted retained earnings (RRE) of $316.6 million.

Capital Resources

The following should be read in conjunction with the unaudited interim financial statements included in this Form 10-Q, the audited financial statements in Item 8. Financial Statements and Supplementary Financial Data and the Capital Resources section of Item 1. Business in the Bank's 2017 Form 10-K.

Risk-Based Capital (RBC)

The Finance Agency’s RBC regulatory framework requires the Bank to maintain sufficient permanent capital, defined as retained earnings plus capital stock, to meet its combined credit risk, market risk and operations risk. Each of these components is computed as specified in regulations and directives issued by the Finance Agency.



(in millions)	June 30, 2018		December 31, 2017
Permanent capital:
Capital stock⁽¹⁾	$	3,955.0	$	3,663.8
Retained earnings	1,215.7		1,157.9
Total permanent capital	$	5,170.7	$	4,821.7
RBC requirement:
Credit risk capital	$	384.4	$	390.4
Market risk capital	654.4		418.9
Operations risk capital	311.6		242.8
Total RBC requirement	$	1,350.4	$	1,052.1
Excess permanent capital over RBC requirement	$	3,820.3	$	3,769.6

Note:

⁽¹⁾Capital stock includes mandatorily redeemable capital stock.

The increase in the total RBC requirement as of June 30, 2018 is mainly related to the change in the market risk capital component. The change was driven by an increase in floating rate debt outstanding and an increase in the severity of the scenarios modeled as a result of higher short-term interest rates. The Finance Agency has issued an Advisory Bulletin effective for RBC reporting beginning with the fourth quarter of 2018, which revises the market risk scenario methodology and significantly lessens the influence of the current level of rates on the scenarios under the current requirements. The Bank expects this to continue under future regulatory requirements. The Bank continues to maintain significant excess permanent capital over the RBC requirement.

On June 7, 2018, the Bank received final notification from the Finance Agency that it was considered "adequately capitalized" for the quarter ended March 31, 2018. As of the date of this filing, the Bank has not received final notice from the Finance Agency regarding its capital classification for the quarter ended June 30, 2018.

Regulatory Capital and Leverage Ratios

In addition to the RBC requirements, the Finance Agency has mandated maintenance of total regulatory capital and leverage ratios of at least 4.0% and 5.0% of total assets, respectively. Management has an ongoing program to measure and monitor compliance with the ratio requirements. The Bank exceeded all regulatory capital requirements at June 30, 2018.



(dollars in millions)	June 30, 2018			December 31, 2017
Regulatory Capital Ratio
Minimum capital (4.0% of total assets)	$	4,072.6		$	3,986.5
Regulatory capital	5,170.7			4,821.7
Total assets	101,814.3			99,663.0
Regulatory capital ratio (regulatory capital as a percentage of total assets)	5.1		%	4.8		%

Leverage Ratio
Minimum leverage capital (5.0% of total assets)	$	5,090.7		$	4,983.2
Leverage capital (permanent capital multiplied by a 1.5 weighting factor)	7,756.0			7,232.5
Leverage ratio (leverage capital as a percentage of total assets)	7.6		%	7.3		%

The Bank's capital stock is owned by its members. The concentration of the Bank's capital stock by institution type is presented below.

The Bank lost five members in the first six months of 2018 and added two new members. One member merged with another institution outside of the Bank's district, and four members merged with another institution within the Bank's district.

Critical Accounting Policies and Estimates

The Bank's financial statements are prepared by applying certain accounting policies. Note 1 - Summary of Significant Accounting Policies in Item 8. Financial Statements and Supplementary Financial Data in the Bank's 2017 Form 10-K describes the most significant accounting policies used by the Bank. In addition, the Bank's critical accounting policies and estimates are presented in Item 7. Management's Discussion and Analysis in the Bank's 2017 Form 10-K. Certain of these policies require management to make estimates or economic assumptions that may prove inaccurate or be subject to variations that may significantly affect the Bank's reported results and financial position for the period or in future periods. Management views these policies as critical accounting policies.

The Bank made no changes to its critical accounting policies during the six months ended June 30, 2018.

In addition to evaluating the Bank's private label MBS portfolio under a base case (or best estimate) scenario, a cash flow analysis was also performed for each of the Bank's private label MBS under a more stressed housing price scenario. This additional scenario was used to determine the amount of credit losses, if any, that would have been recorded in earnings during the quarter ended June 30, 2018, if the more stressed housing price scenario had been used in the Bank's OTTI assessment as of June 30, 2018. The more stressed scenario results were immaterial. A more detailed discussion of this analysis is in the OTTI section of Credit and Counterparty Risk - Investments of this Item 2.

See Note 1 - Changes in Accounting Principle and Recently Issued Accounting Standards and Interpretations to the unaudited financial statements in this Form 10-Q for information on new accounting pronouncements impacting the financial statements or becoming effective for the Bank in future periods.

Legislative and Regulatory Developments

Adoption of Single-Counterparty Credit Limits for Bank Holding Companies and Foreign Banking Organizations by Board of Governors of the Federal Reserve System. On June 14, 2018, the Board of Governors of the Federal Reserve System voted to pass a final rule establishing single-counterparty credit limits applicable to bank holding companies and foreign banking organizations with total consolidated assets of $250 billion or more, including global systemically important bank holding companies (GSIBs) in the United States. These entities are considered to be “covered companies” under the rule. The FHLBanks are exempt from the limits and reporting requirements contained in this rule. However, credit exposure to individual FHLBanks must be monitored and reported on, as required, by any entity that is a covered company under this rule.

Under the final rule, a covered company and its subsidiaries may not have aggregate net credit exposure to an FHLBank and (in certain cases) economically interdependent entities in excess of 25% of the company’s tier 1 capital. Such credit exposure does not include advances from an FHLBank, but generally includes collateral pledged to an FHLBank in excess of a covered company’s outstanding advances. Also included towards a covered company’s net credit exposure is its investment in FHLBank capital stock and debt instruments; deposits with an FHLBank; FHLBank-issued letters of credit where a covered company is the named beneficiary; and other obligations to an FHLBank, including repurchase or reverse repurchase transactions net of collateral that create a credit exposure to an FHLBank. Intra-day exposures are exempt from the final rule.

With respect to the FHLBanks’ consolidated obligations held by a covered company, the company must monitor, and report on as required, its credit exposure for such obligations. It is not clear if the Federal Reserve will require consolidated obligations to be aggregated with other exposures to an FHLBank or the FHLBank System.

The final rule gives major covered companies (i.e., the GSIBs) until January 1, 2020 to comply; all other covered companies will have until July 1, 2020 to comply. The Bank is continuing to study the overall impact of the rule, but does not believe it will materially affect its financial condition or results of operations.

Risk Management

The Bank employs a corporate governance and internal control framework designed to support the effective management of the Bank’s business activities and the related inherent risks. As part of this framework, the Board has approved a Risk Governance Policy and a Member Products Policy, both of which are reviewed regularly and re-approved at least annually. The Risk Governance Policy establishes risk guidelines, limits (if applicable), and standards for credit risk, market risk, liquidity risk, operational risk, and business risk in accordance with Finance Agency regulations and consistent with the Bank’s risk appetite. The Member Products Policy establishes the eligibility and authorization requirements, policy limits and restrictions, and the terms applicable to each type of Bank product or service, as well as collateral requirements. The risk appetite is established by the Board, as are other applicable guidelines in connection with the Bank’s Capital Plan and overall risk management.

Risk Governance

The Bank’s lending, investment and funding activities and use of derivative instruments expose the Bank to a number of risks that include, among others:

•market and interest rate risk;

•credit and counterparty risk;

•liquidity and funding risk; and

•operational and business risk.

In addition, the Bank’s risks are affected by current and projected financial and residential mortgage market trends, including those described in Item 1A. Risk Factors in the Bank's 2017 Form 10-K. Details regarding the Bank's risk governance framework and processes are included in the "Risk Governance" discussion in Risk Management in Item 7. Management's Discussion and Analysis in the Bank's 2017 Form 10-K.

Capital Adequacy Measures. MV/CS provides a current assessment of the liquidation value of the balance sheet and measures the Bank's current ability to honor the par put redemption feature of its capital stock. This is one of the risk metrics used to evaluate the adequacy of retained earnings, which is used to develop dividend payment recommendations and support the repurchase of excess capital stock.

The current Board-approved floor for MV/CS is 90.0%. MV/CS is measured against the floor monthly. When MV/CS is below the established floor, excess capital stock repurchases and dividend payouts are restricted. See the “Capital and Retained Earnings” discussion in Financial Condition in this Item 2 for details regarding the Bank’s retained earnings policy. The MV/CS ratio was 136.1% at June 30, 2018 and 136.3% at December 31, 2017.

Qualitative and Quantitative Disclosures Regarding Market Risk

Managing Market Risk. The Bank's market risk management objective is to protect member/shareholder and bondholder value consistent with the Bank's housing mission and safe and sound operations across a wide range of interest rate environments. Management believes that a disciplined approach to market risk management is essential to maintaining a strong capital base and uninterrupted access to the capital markets.

The Bank's Market Risk Model. Significant resources are devoted to ensuring that the level of market risk in the balance sheet is accurately measured, thus allowing management to monitor the risk against policy and regulatory limits. The Bank uses externally developed models to evaluate its financial position and market risk. One of the most critical market-based models relates to the prepayment of principal on mortgage-related instruments. Management regularly reviews the major assumptions and methodologies used in its models, as well as the performance of the models relative to empirical results, so that appropriate changes to the models can be made.

The Bank regularly validates the models used to measure market risk. Such model validations are performed by third-party specialists or the Bank's model risk management department, which are separate from the model owner. The model validations are supplemented by additional validation processes performed by the Bank, most notably benchmarking model-derived fair values to those provided by third-party services or alternative internal valuation models. This analysis is performed by a group that is separate from the model owner. Results of the validation process, as well as any changes in valuation methodologies and the benchmarking analysis, are reported to the Bank's Asset and Liability Committee (ALCO), which is responsible for reviewing and approving the approaches used in the valuation of such risks to ensure that they are well controlled and effective and result in reasonable fair values.

Duration of Equity. One key risk metric used by the Bank is duration. Duration is a measure of the sensitivity of a financial instrument's value, or the value of a portfolio of instruments, to a 100 basis point parallel shift in interest rates. Duration (typically expressed in years) is commonly used by investors throughout the fixed income securities market as a measure of financial instrument price sensitivity.

The Bank's asset/liability management policy approved by the Board calls for actual duration of equity to be maintained within a + 4.5 year range in the base case. In addition, the duration of equity exposure limit in an instantaneous parallel interest rate shock of + 200 basis points is + 7 years. Management analyzes the duration of equity exposure against this policy limit on a daily basis and regularly evaluates its market risk management strategies.

The following table presents the Bank's duration of equity exposure at June 30, 2018 and December 31, 2017. Given the low level of interest rates, an instantaneous parallel interest rate shock of "down 200 basis points" could not be meaningfully measured for these periods and therefore is not presented. The "down 100 basis point" scenario results became meaningful during the first quarter of 2018 due to an increase in short term interest rates and therefore is only presented for June 30, 2018.



(in years)	Down 100 basis points	Base Case	Up 100 basis points	Up 200 basis points
Actual Duration of Equity:
June 30, 2018	(0.4)	0.0	0.3	0.6
December 31, 2017	n/a	0.0	0.2	0.6

Duration of equity changes in the first six months of 2018 were minimal. The Bank continues to monitor the mortgage and related fixed-income markets, including the impact that changes in the market or anticipated modeling changes may have on duration of equity and other market risk measures and may take actions to reduce market risk exposures as needed. Management believes that the Bank's current market risk profile is reasonable given these market conditions.

Return on Equity (ROE) Spread Volatility. Interest rate risk is also measured based on the volatility in the Bank’s projected return on capital in excess of the return of an established benchmark market index. ROE spread is defined as the Bank's return on average equity, including capital stock and retained earnings, in excess of the average of 3-month LIBOR. ROE spread volatility is a measure of the variability of the Bank’s projected ROE spread in response to shifts in interest rates and represents the change in ROE spread compared to an ROE spread that is generated by the Bank in its base forecasting scenario. ROE spread volatility is measured over a rolling forward 12 month period for selected interest rate scenarios and excludes the income sensitivity resulting from mark-to-market changes, which are separately described below.

The ROE spread volatility presented in the table below reflects spreads relative to 3-month LIBOR. Management uses both parallel and non-parallel rate scenarios to assess interest rate risk. The steeper and flatter yield curve shift scenarios are represented by appropriate increases and decreases in short-term and long-term interest rates using the three-year point on the yield curve as the pivot point. Given the low rate environment, management replaced a "down 200 basis points parallel rate" scenario with a "down 100 basis point longer term rate" shock as an additional non-parallel rate scenario that reflects a decline in longer-term rates. Due to increases in short-term interest rates, the Bank had re-introduced a "down 50 basis point parallel rate" scenario during the first quarter of 2017. As a result of further increases in short term interest rates, the Bank replaced this "down 50 basis point parallel rate" scenario with a "down 100 basis point parallel rate" scenario during the first quarter of 2018.



ROE Spread Volatility Increase/(Decline)
(in basis points)	Down 100 bps Longer Term Rate Shock	Down 100 bps Parallel Shock	100 bps Steeper	100 bps Flatter	Up 200 bps Parallel Shock
June 30, 2018	(5)	(24)	(24)	7	(3)
December 31, 2017	(13)	n/a	(8)	2	(10)

Changes in ROE spread volatility in the first six months of 2018 were minimal. For each scenario, the Board's limit on the decline in ROE spread is set at no greater than 100 basis points. The Bank was in compliance with the ROE spread volatility limit across all selected interest rate shock scenarios at June 30, 2018 and December 31, 2017.

Mark-to-Market Risk. The Bank measures earnings risk associated with certain mark-to-market positions, including economic hedges. This framework measures forward-looking, scenario-based exposure based on interest rate and volatility shocks that are applied to any existing transaction that is marked to market through the income statement without an offsetting mark arising from a qualifying hedge relationship. In addition, the Bank's Capital Markets and Corporate Risk Management departments monitor the actual profit/loss change on a daily, monthly cumulative, and quarterly cumulative basis. The Bank's ALCO monitors mark-to-market risk through a daily exposure guideline and quarterly profit/loss reporting trigger.

Credit and Counterparty Risk - Total Credit Exposure (TCE) and Collateral

TCE. The Bank manages the credit risk of each member on the basis of the member’s total credit exposure (TCE) to the Bank, which includes advances and related accrued interest, fees, basis adjustments and estimated prepayment fees; letters of credit; forward-dated advance commitments; and MPF credit enhancement and related obligations. This credit risk is managed by monitoring the financial condition of borrowers and by requiring all borrowers (and, where applicable in connection with member affiliate pledge arrangements approved by the Bank, their affiliates) to pledge sufficient eligible collateral for all borrower obligations to the Bank to ensure that all potential forms of credit-related exposures are covered by sufficient eligible collateral. At June 30, 2018, aggregate TCE was $96.7 billion, comprised of approximately $76.6 billion in advance principal outstanding, $19.7 billion in letters of credit (including forward commitments), $13.5 million in advance commitments, and $339.3 million in accrued interest, prepayment fees, MPF credit enhancement obligations and other fees.

The Bank establishes a maximum borrowing capacity (MBC) for each member based on collateral weightings applied to eligible collateral as described in the Bank’s Member Products Policy. Details regarding this policy are available in the Advance Products discussion in Item 1. Business in the Bank's 2017 Form 10-K. According to the Policy, eligible collateral is weighted to help ensure that the collateral value will exceed the amount that may be owed to the Bank in the event of a default. The Bank also has the ability to call for additional or substitute collateral while any indebtedness is outstanding to protect the Bank’s fully secured position. At June 30, 2018 and December 31, 2017, on a borrower-by-borrower basis, the Bank had a perfected security interest in eligible collateral with an estimated collateral value (after collateral weightings) in excess of the book value of all members’ and nonmember housing associates’ obligations to the Bank.

The financial condition of all members and eligible non-member housing associates is closely monitored for compliance with financial criteria as set forth in the Bank’s credit policies. The Bank has developed an internal credit rating (ICR) system that calculates financial scores and rates member institutions on a quarterly basis using a numerical rating scale from one to ten, with one being the best rating. Generally, scores are objectively calculated based on financial ratios computed from publicly available data. The scoring system gives the highest weighting to the member’s asset quality and capitalization. Other key factors include earnings and balance sheet composition. Operating results which include net income, capital levels, reserve coverage and other factors for the previous four quarters are used. The most recent quarter’s results are given a higher weighting. Additionally, a member’s credit score can be adjusted for various qualitative factors, such as the financial condition of the member’s holding company. A rating in one of the higher number (i.e., worse) categories indicates that a member exhibits well defined financial weaknesses as described in the policy. Members in these categories are reviewed for potential collateral delivery status. Other uses of the ICR include the scheduling of on-site collateral reviews. Insurance company members are rated on the same credit scale as depository institutions, but the analysis includes both quantitative and qualitative factors. While depository institution member analysis is based on standardized regulatory Call Report data and risk modeling, insurance company credit risk analysis is based on various forms of financial data, including, but not limited to, statutory reporting filed by insurance companies with state insurance regulators, which requires specialized methodologies and dedicated underwriting resources.

Management believes that it has adequate policies and procedures in place to effectively manage credit risk exposure related to member TCE. These credit and collateral policies balance the Bank’s dual goals of meeting members’ needs as a reliable source of liquidity and limiting credit loss by adjusting the credit and collateral terms in response to deterioration in creditworthiness. The Bank has never experienced a loss on its member advance exposure.

The following table presents the Bank’s top five members with respect to their TCE at June 30, 2018.

The average year-to-date June 30, 2018 balances for the five largest borrowers totaled $55.3 billion, or 76.4% of total average advances outstanding. The advances made by the Bank to each of these borrowers are secured by collateral with an estimated value, after collateral weightings, in excess of the book value of the advances. The Bank has never incurred any losses on these advances. The Bank has implemented specific credit and collateral review monitoring for these members.

Letters of Credit. The following table presents the Bank’s total outstanding letters of credit as of June 30, 2018 and December 31, 2017. The letter of credit product is collateralized under the same policies, procedures and guidelines that apply to advances.

At June 30, 2018, the Bank had a concentration of letters of credit with two members (TD Bank and PNC Bank) totaling $12.0 billion or 64.1% of the total amount. At December 31, 2017, $12.2 billion or 64.2% of the letters of credit were concentrated with these same two members.

Collateral Policies and Practices. All members are required to maintain eligible collateral to secure their TCE. Refer to the Risk Management section of the Bank's 2017 Form 10-K for additional information related to the Bank’s Collateral Policy.

Collateral Agreements and Valuation. The Bank provides members with two types of collateral agreements: a blanket lien collateral pledge agreement and a specific collateral pledge agreement. Under a blanket lien agreement, the Bank obtains a lien against all of the member’s unencumbered eligible collateral assets and most ineligible assets to secure the member’s obligations with the Bank. Under a specific collateral pledge agreement, the Bank obtains a lien against specific eligible collateral assets of the member or its affiliate (if applicable) to secure the member’s obligations with the Bank. The member provides a detailed listing, as an addendum to the specific collateral agreement, identifying those assets pledged as collateral or delivered to the Bank or its third party custodian. Details regarding average lending values provided under both blanket liens and specific liens and delivery arrangements are available in the "Credit and Counterparty Risk - TCE and Collateral" discussion in Risk Management in Item 7. Management's Discussion and Analysis in the Bank's 2017 Form 10-K.

High quality investment securities are defined as U.S. Treasury and U.S. Agency securities, REFCORP bonds, GSE MBS, commercial and residential private label MBS with a minimum credit rating of single A, which the Bank considers as part of its evaluation of the collateral. In addition, municipal securities (or portions thereof) with a real estate nexus (e.g. proceeds primarily used for real estate development) with a minimum credit rating of single A are included. Members have the option to deliver such high quality investment securities to the Bank to increase their maximum borrowing capacity. Upon delivery, these securities are valued daily and all non-government or agency securities are subject to weekly ratings reviews. Reported amount also includes pledged FHLBank cash deposits.

For all of the Bank's members, the following table summarizes total eligible collateral values, after collateral weighting, by type under both blanket lien and specific collateral pledge agreements as of June 30, 2018 and December 31, 2017. The amount of excess collateral by individual borrowers varies significantly.

Credit and Counterparty Risk - Investments

The Bank is also subject to credit risk on investments consisting of money market investments and investment securities. The Bank considers a variety of credit quality factors when analyzing potential investments, including collateral performance, marketability, asset class or sector considerations, local and regional economic conditions, credit ratings based on NRSROs, and/or the financial health of the underlying issuer. As of June 30, 2018 and December 31, 2017, the Bank’s carrying value of investment securities issued by entities other than the U.S. government, Federal agencies or GSEs was $3.4 billion and $1.6 billion, respectively.

Investment Quality and External Credit Ratings. The following tables present the Bank’s investment carrying values as of June 30, 2018 and December 31, 2017, based on the lowest credit rating from the NRSROs (Moody’s, S&P and Fitch).

The Bank also manages credit risk based on an internal credit rating system. For purposes of determining the internal credit rating, the Bank measures credit exposure through a process which includes internal credit review and various external factors, including placement of the counterparty on negative watch by one or more NRSROs. For internal reporting purposes, the incorporation of negative credit watch into the credit rating analysis of an investment may translate into a downgrade of one credit rating level from the external rating. The Bank does not rely solely on any NRSRO rating in deriving its final internal credit rating.

Short-term Investments. Within the portfolio of short-term investments, the Bank faces credit risk from unsecured exposures. The Bank's unsecured credit investments have maturities generally ranging between overnight and six months and may include the following types:


•	Interest-bearing deposits. Primarily consists of unsecured deposits that earn interest;


•	Federal funds sold. Unsecured loans of reserve balances at the Federal Reserve Banks between financial institutions that are made on an overnight and term basis; and


•	Certificates of deposit. Unsecured negotiable promissory notes issued by banks and payable to the bearer at maturity or on demand.

Under the Bank’s Risk Governance Policy, the Bank can place money market investments, which include those investment types listed above, on an unsecured basis with large financial institutions with long-term credit ratings no lower than BBB. Management actively monitors the credit quality of these counterparties.

As of June 30, 2018, the Bank had unsecured exposure to 17 counterparties totaling $8.3 billion, with three counterparties each exceeding 10% of the total exposure. The following table presents the Bank's unsecured credit exposure with non-governmental counterparties by investment type at June 30, 2018 and December 31, 2017. The unsecured investment credit exposure presented may not reflect the average or maximum exposure during the period.

As of June 30, 2018, 76% of the Bank’s unsecured investment credit exposures were to U.S. branches and agency offices of foreign commercial banks. The Bank actively monitors its credit exposures and the credit quality of its counterparties, including an assessment of each counterparty’s financial performance, capital adequacy, sovereign support, and the current market perceptions of the counterparties. General macro-economic, political and market conditions may also be considered when deciding on unsecured exposure. As a result, the Bank may limit or suspend existing exposures.

Finance Agency regulations include limits on the amount of unsecured credit the Bank may extend to a counterparty or to a group of affiliated counterparties. This limit is based on a percentage of eligible regulatory capital and the counterparty's overall credit rating. Under these regulations, the level of eligible regulatory capital is determined as the lesser of the Bank's total regulatory capital or the eligible amount of regulatory capital of the counterparty. The eligible amount of regulatory capital is then multiplied by a stated percentage. This percentage is 1% to 15% and is based on the counterparty's credit rating. The calculation of term extensions of unsecured credit includes on-balance sheet transactions, off-balance sheet commitments, and derivative transactions.

Finance Agency regulation also permits the Bank to extend additional unsecured credit for overnight transactions and for sales of Federal funds subject to continuing contracts that renew automatically. For overnight exposures only, the Bank's total unsecured exposure to a counterparty may not exceed twice the applicable regulatory limit, or a total of 2% to 30% of the eligible amount of regulatory capital, based on the counterparty's credit rating. As of June 30, 2018, the Bank was in compliance with the regulatory limits established for unsecured credit.

The Bank's unsecured credit exposures to U.S. branches and agency offices of foreign commercial banks include the risk that, as a result of political or economic conditions in a country, the counterparty may be unable to meet their contractual repayment obligations. The Bank's unsecured credit exposures to domestic counterparties and U.S. subsidiaries of foreign commercial banks include the risk that these counterparties have extended credit to foreign counterparties.

The following table presents the long-term credit ratings of the unsecured investment credit exposures by the domicile of the counterparty or the domicile of the counterparty's immediate parent for U.S. subsidiaries or branches and agency offices of foreign commercial banks based on the NRSROs used. This table does not reflect the foreign sovereign government's credit rating.

U.S. Treasury Bills, Agency Securities, GSE Securities and State and Local Agency Obligations. In addition to U.S. Treasury bills and securities issued or guaranteed by U.S. Agencies or U.S. government corporations, the Bank invests in and is subject to credit risk related to GSE securities and state and local agency obligations. Further, the Bank maintains a portfolio of state and local agency obligations to enhance net interest income. These portfolios totaled $3.3 billion and $3.6 billion at June 30, 2018 and December 31, 2017, respectively.

Agency and GSE MBS. The Bank invests in and is subject to credit risk related to MBS issued or guaranteed by Federal agencies and GSEs that are directly supported by underlying mortgage loans. The Bank’s total agency and GSE MBS portfolio was $6.9 billion at June 30, 2018 and $6.7 billion at December 31, 2017.

Private Label MBS. The Bank also holds investments in private label MBS, which are supported by underlying mortgage loans. The Bank made investments in private label MBS that were rated AAA at the time of purchase with the exception of one, which was rated AA at the time of purchase. However, since the time of purchase, there have been significant downgrades. Current ratings are in the table below. In late 2007, the Bank discontinued the purchase of private label MBS.

The carrying value of the Bank’s private label MBS portfolio at June 30, 2018 was $714.4 million, which was a decrease of $88.8 million from December 31, 2017. This decline was primarily due to repayments.

Unrealized gains of OTTI securities in AOCI at June 30, 2018 were $76.4 million compared to $72.9 million at December 31, 2017. The weighted average prices on OTTI securities were 90.4 and 89.5 at June 30, 2018 and December 31, 2017, respectively. These fair values are determined using unobservable inputs (i.e., Level 3) derived from multiple third-party pricing services. There continues to be unobservable inputs and a lack of significant market activity for private label MBS; therefore, as of June 30, 2018, the Bank classified private label MBS as Level 3. The Bank uses the unadjusted prices received from the third-party pricing services in its process relating to fair value calculations and methodologies as described further in the Critical Accounting Policies and Estimates section in Item 7. Management’s Discussion and Analysis in the Bank's 2017 Form 10-K.

Participants in the mortgage market have often characterized single family loans based upon their overall credit quality at the time of origination, generally considering them to be Prime, Alt-A or subprime. There has been no universally accepted definition of these segments or classifications. The subprime segment of the mortgage market primarily served borrowers with poorer credit payment histories, and such loans typically had a mix of credit characteristics that indicate a higher likelihood of default and higher loss severities than Prime loans. Further, many mortgage participants classified single family loans with credit characteristics that range between Prime and subprime categories as Alt-A because these loans had a combination of characteristics of each category or may have been underwritten with low or no documentation compared to a full documentation mortgage loan. Industry participants often used this classification principally to describe loans for which the underwriting process was less rigorous and the documentation requirements of the borrower were reduced.

Private Label MBS Collateral Statistics. The following tables provide collateral performance and credit enhancement information for the Bank’s private label MBS portfolio by par and by collateral type as of June 30, 2018.

Notes:

⁽¹⁾Represents total gross unrealized losses including non-credit-related other-than-temporary impairment recognized in AOCI. The unpaid principal balance and amortized cost of private label MBS in a gross unrealized loss position were both $20.5 million at June 30, 2018.

⁽²⁾For the six months ended June 30, 2018.

⁽³⁾Delinquency information is presented at the cross-collateralization level.

OTTI. The Bank recognized $0.1 million of credit-related OTTI charges in earnings during the three months ended June 30, 2018 and none during the three months ended June 30, 2017, and $0.4 million and $0.7 million during the six months ended June 30, 2018 and 2017, respectively. Because the Bank does not intend to sell and it is not more likely than not that the Bank will be required to sell any OTTI securities before anticipated recovery of their amortized cost basis, the Bank does not have an additional OTTI charge for the difference between amortized cost and fair value. The Bank has not recorded OTTI on any other type of security (i.e., U.S. Agency MBS or non-MBS securities).

The Bank’s estimate of cash flows has a significant impact on the determination of credit losses. Cash flows expected to be collected are based on the performance and type of private label MBS and the Bank’s expectations of the economic environment. To ensure consistency in determination of the OTTI for private label MBS among all FHLBanks, each quarter the Bank works with the OTTI Governance Committee to update its OTTI analysis based on actual loan performance and current housing market assumptions in the collateral loss projection models, which generate the estimated cash flows from the Bank’s private label MBS. This process is described in Note 5 - OTTI to the unaudited financial statements included in this Form 10-Q.

The Bank’s quarterly OTTI analysis is based on current and forecasted economic trends. Significant assumptions used on the Bank’s private label MBS as part of its second quarter of 2018 analysis are presented below.



	Significant Inputs for Private Label Residential MBS
Category at origination	Prepayment Rates	Default Rates	Loss Severities	Current Credit Enhancement
	Weighted Avg %	Weighted Avg %	Weighted Avg %	Weighted Avg %
Prime	13.7	10.1	24.7	7.4
Alt-A	14.0	19.3	38.2	3.7
Subprime	4.4	26.2	54.9	48.5
Total Private Label Residential MBS	13.8	14.6	31.4	5.8

The Bank’s life-to-date credit losses are concentrated in its 2006 and 2007 vintage bonds. These vintages represent 92% of life-to-date credit losses, of which 48% relates to Prime and 44% relates to Alt-A, with the remainder in subprime and HELOC. The Bank has recognized life to date OTTI as follows:



(dollars in millions)	June 30, 2018			June 30, 2017
Number of private label MBS with an OTTI charge:
Life-to-date	60			60
Still outstanding	38			39
Total OTTI credit loss recorded life-to-date	$	457.4		$	456.8
Principal write-downs on private label MBS	(154.6		)	(149.8		)
Credit losses on private label MBS no longer owned:
Private label MBS sold	(116.5		)	(116.5		)
Private label MBS matured (less principal write-downs realized)	(7.1		)	(5.5		)
Remaining amount of previously recognized OTTI credit losses	$	179.2		$	185.0

The table above excludes recoveries of OTTI through interest income, which occur if there is a significant increase in estimated cash flows whereby the Bank increases the yield on the Bank’s investment and recognizes recovery as interest income over the life of the investment. OTTI recovered through interest income on these securities was $4.9 million and $6.9 million for the second quarter of 2018 and 2017, respectively; $10.1 million and $13.6 million for the first six months of 2018 and 2017, respectively; and $148.9 million life-to-date. The OTTI recovered through interest income was recognized on 34 and 35 private label MBS securities for the first six months of 2018 and 2017, respectively. The same private label MBS can have multiple increases in cash flows that are deemed to be significant.

The Bank transfers private label MBS from HTM to AFS when an OTTI credit loss is recorded on a security. The Bank believes that a credit loss constitutes evidence of deterioration in the credit quality of the security. The Bank believes that the transfer increases its flexibility to potentially sell other-than-temporarily-impaired securities if it makes economic sense. There were no transfers during the first six months of 2018 and 2017.

Management will continue to evaluate all impaired securities, including those on which OTTI has been recorded. Material credit losses have occurred on private label MBS and may occur in the future. The specific amount of credit losses will depend on the actual performance of the underlying loan collateral, payments received on the securities themselves, as well as the Bank’s future modeling assumptions. Those securities for which the Bank is recognizing recovery of OTTI may be more likely to incur a credit loss due to the nature of the accounting. The Bank cannot estimate the future amount of any additional credit losses. The FASB issued guidance which will amend the accounting for credit losses beginning January 1, 2020. See Note 1 to the Financial Statements for additional discussion.

As discussed above, the projection of cash flows expected to be collected on private label MBS involves significant judgment with respect to key modeling assumptions. Therefore, on all private label MBS, the Bank performed a cash flow analysis under one additional scenario which was agreed to by the OTTI Governance Committee that represented meaningful, plausible and more adverse external assumptions. This more adverse scenario decreases the short-term housing price forecast by five percentage points and slows housing price recovery rates by 33%. The adverse scenario estimated cash flows were generated using the same model (Prime, Alt-A or subprime) as the base scenario. Using a model with more severe assumptions could increase the estimated credit loss recorded by the Bank. The securities included in this stress scenario were only those

that were in an unrealized loss position at June 30, 2018. Additionally, the maximum credit loss under the adverse case was limited to the amount of the security's unrealized loss. The adverse case housing price forecast is not management’s current best estimate of cash flows and is therefore not used as a basis for determining OTTI. The results of the analysis were immaterial.

Credit and Counterparty Risk - Mortgage Loans, BOB Loans and Derivatives

Mortgage Loans. The Finance Agency has authorized the Bank to hold mortgage loans under the MPF Program whereby the Bank acquires mortgage loans from participating members in a shared credit risk structure. These assets carry CEs, although the CE is not rated. The CE was originally established to be sufficient such that a Master Commitment (MC) has a AA credit rating. The Bank has revised this requirement to a BBB credit rating for all new MCs and legacy MCs for specific products. The Bank had net mortgage loans held for portfolio of $4.2 billion and $3.9 billion after an allowance for credit losses of $8.0 million at June 30, 2018 and $6.0 million at December 31, 2017, respectively.

Mortgage Insurers. The Bank’s MPF Program currently has credit exposure to nine mortgage insurance companies which provide PMI and/or Supplemental Mortgage Insurance (SMI) for the Bank’s various products. The Bank monitors the financial condition of these mortgage insurers. PMI for MPF Program loans must be issued by a mortgage insurance company on the approved mortgage insurance company list whenever PMI coverage is required.

None of the Bank’s mortgage insurers currently maintain a rating by at least one NRSRO of A+ or better. Given the credit deterioration of PMI providers, the estimate of the allowance for credit losses includes projected reduced claim payments. As required by the MPF Program, for originations with PMI, the ratings model currently requires additional CE from the PFI to compensate for the mortgage insurer rating when it is below A+.

The MPF Plus product required SMI under the MPF Program when each pool was established. At June 30, 2018, six of the 14 MPF Plus pools still have SMI policies in place. The Bank does not currently offer the MPF Plus product and has not purchased loans under MPF Plus Commitments since July 2006. Per MPF Program guidelines, the existing MPF Plus product exposure is required to be secured by the PFI once the SMI company is rated below AA-. The Finance Agency guidelines require mortgage insurers that underwrite SMI to be rated AA- or better. This requirement has been temporarily waived by the Finance Agency provided that the Bank otherwise mitigates the risk by requiring the PFI to secure the exposure. As of June 30, 2018, all of the SMI exposure is fully collateralized.

The unpaid principal balance and maximum coverage outstanding for seriously delinquent loans with PMI as of June 30, 2018 was $5.8 million and $2.3 million, respectively. The corresponding amounts at December 31, 2017 were $6.4 million and $2.6 million.

BOB Loans. See Note 1 - Summary of Significant Accounting Policies in Item 8 in the Bank's 2017 Form 10-K for a description of the BOB program. At June 30, 2018, the allowance for credit losses on BOB loans was $2.4 million, an increase of $0.5 million from December 31, 2017.

Derivative Counterparties. To manage interest rate risk, the Bank enters into derivative contracts. Derivative transactions may be either executed with a counterparty (referred to as uncleared derivatives) or cleared through a Futures Commission Merchant (i.e., clearing agent) or a Swap Execution Facility with a Derivatives Clearing Organization (referred to as cleared derivatives). For uncleared derivatives, the Bank transacts most of its derivatives with large banks and major broker-dealers. Some of these banks and broker-dealers or their affiliates buy, sell, and distribute consolidated obligations. The Bank is not a derivatives dealer and does not trade derivatives for short-term profit.

The Bank uses CME Clearing as the Clearing House for all cleared derivative transactions. Variation margin payments are characterized as daily settlement payments, rather than collateral. Initial margin is considered cash collateral. The Bank is subject to credit risk due to the risk of non-performance by counterparties to its derivative transactions. The amount of credit risk on derivatives depends on the extent to which netting procedures, collateral requirements, daily settlement and other credit enhancements are used and are effective in mitigating the risk. The Bank manages credit risk through credit analysis, collateral management, and other credit enhancements.

Uncleared Derivatives. The Bank is subject to non-performance by counterparties to its uncleared derivative transactions. The Bank requires collateral on uncleared derivative transactions. 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 the Bank if the total market value of the Bank's exposure to that counterparty rises above a specific trigger point.

As a result of these risk mitigation initiatives, the Bank does not anticipate any credit losses on its uncleared derivative transactions with counterparties as of June 30, 2018.

Cleared Derivatives. The Bank is subject to credit risk exposure to the Clearing Houses and clearing agent. The requirement that the Bank post initial margin and exchange variation margin settlement payments, through the clearing agent, to the Clearing Houses, exposes the Bank to institutional credit risk in the event that the clearing agent or the Clearing Houses fail to meet their obligations. Initial margin is the amount calculated based on anticipated exposure to future changes in the value of a swap and protects the Clearing Houses from market risk in the event of default by one of its clearing agents. Variation margin is the amount accumulated through daily settlement of the current exposure arising from changes in the market value of the position since the trade was executed. The Bank's use of cleared derivatives is intended to mitigate credit risk exposure because a central counterparty is substituted for individual counterparties and collateral postings and variation margin settlement payments are made daily for changes in the value of cleared derivatives through a clearing agent. The Bank does not anticipate any credit losses on its cleared derivatives as of June 30, 2018.

The contractual or notional amount of derivative transactions reflects the involvement of the Bank in the various classes of financial instruments. The maximum credit risk of the Bank with respect to derivative transactions is the estimated cost of replacing the derivative transactions if there is a default, minus the value of any related collateral, including initial margin and variation margin settlements on cleared derivatives. In determining maximum credit risk, the Bank considers accrued interest receivables and payables as well as the netting requirements to net assets and liabilities. The following table presents the derivative positions with non-member counterparties and member institutions to which the Bank has credit exposure at June 30, 2018 and December 31, 2017.

To appropriately assess potential credit risk to its European holdings, the Bank annually underwrites each counterparty and country and regularly monitors NRSRO rating actions and other publications for changes to credit quality. The Bank also actively monitors its counterparties' approximate indirect exposure to European sovereign debt and considers this exposure as a component of its credit risk review process.

Liquidity and Funding Risk

As a wholesale bank, the Bank employs financial strategies which enable it to expand and contract its assets, liabilities and capital in response to changes in member credit demand, membership composition and other market factors. In addition, the Bank is required to maintain a level of liquidity in accordance with the FHLBank Act, FHFA regulations and policies established by its management and board of directors. The Bank's liquidity resources are designed to support these strategies and requirements and are described further in the Bank's 2017 Form 10-K.

Asset/Liability Maturity Profile. The Bank is focused on maintaining adequate liquidity and funding balances with its financial assets and financial liabilities, and the FHLBanks work collectively to manage system-wide liquidity and funding needs. The FHLBanks jointly monitor the combined risks, primarily by tracking the maturities of financial assets and financial liabilities. The Bank also monitors the funding balance between financial assets and financial liabilities and is committed to prudent risk management practices. External factors including member borrowing needs, supply and demand in the debt markets, and other factors may affect liquidity balances and the funding balances between financial assets and financial liabilities.

Sources of Liquidity. The Bank's primary sources of liquidity are proceeds from the issuance of consolidated obligations and a liquidity investment portfolio, along with maturing advances and proceeds from the issuance of capital stock.

Consolidated Obligations. The Bank’s ability to operate its business, meet its obligations and generate net interest income depends primarily on the ability to issue large amounts of various debt structures at attractive rates. Investor demand for FHLBank debt remains strong as money market reform continues to provide strong demand for discount and floating rate notes. Consolidated obligation bonds and discount notes are rated Aaa with stable outlook/P-1 by Moody’s and AA+ with stable outlook/A-1+ by S & P, as of June 30, 2018. These ratings measure the likelihood of timely payment of principal and interest. Note 10 - Consolidated Obligations to the unaudited financial statements in this Form 10-Q provides additional information regarding the Bank’s consolidated obligations.

Liquidity Investment Portfolio. The Bank’s operating liquidity is comprised of cash, interest-bearing deposits, Federal funds sold and securities purchased under agreements to resell. In addition, U.S. Treasury and GSE obligations that are classified as trading securities are also included in operating liquidity.

Contingency Liquidity. The Bank’s access to the capital markets has never been interrupted to the extent that the Bank’s ability to meet its obligations was compromised, and the Bank currently has no reason to believe that its ability to issue consolidated obligations will be impeded to that extent. The Bank maintains a contingency liquidity portfolio in the event it is unable to access the capital markets. In addition to its liquidity investment portfolio above, the Bank's sources of contingency liquidity include advances maturing within five days, certificates of deposit, unencumbered repurchase-eligible assets within its AFS and HTM securities portfolios and MBS repayments expected within five days. Uses of contingency liquidity include net settlements of consolidated obligations, member loan commitments, mortgage loan purchase commitments, deposit outflows and maturing other borrowed funds. Excess contingency liquidity is calculated as the difference between sources and uses of contingency liquidity. At June 30, 2018 and December 31, 2017, excess contingency liquidity was approximately $24.3 billion and $25.6 billion, respectively.

Funding and Debt Issuance. Changes or disruptions in the capital markets could limit the Bank’s ability to issue consolidated obligations. During the first half of 2018, the Bank maintained continual access to funding. Access to short-term debt markets has been reliable because investors, driven by increased liquidity preferences and risk aversion, including the effects of money market fund reform, have sought the FHLBank’s short-term debt as an asset of choice. This has led to advantageous funding opportunities and increased utilization of debt maturing in one year or less. The FHLBanks have comparatively stable access to funding through a diverse investor base at relatively favorable spreads to U.S. Treasury rates.

Refinancing Risk. There are inherent risks in utilizing short-term funding to support longer-dated assets and the Bank may be exposed to refinancing and investor concentration risks (collectively, refinancing risk). Refinancing risk includes the risk the Bank could have difficulty in rolling over short-term obligations when market conditions change. In managing and monitoring the amounts of financial assets that require refinancing, the Bank considers their contractual maturities, as well as certain assumptions regarding expected cash flows (i.e., estimated prepayments, embedded call optionality, and scheduled amortizations). The Bank and the OF jointly monitor the combined refinancing risk of the FHLBank system. In managing and monitoring the amounts of assets that require refunding, the Bank may consider contractual maturities of the financial assets, as well as certain assumptions regarding expected cash flows (i.e., estimated prepayments and scheduled amortizations).

Interest Rate Risk. The Bank may use a portion of the short-term consolidated obligations issued to fund both short- and long-term LIBOR-indexed assets. However, funding longer-term LIBOR-indexed assets with shorter-term liabilities generally does not expose the Bank to interest rate risk because the rates on the LIBOR-indexed assets reset similar to the liabilities. The Bank measures and monitors interest rate-risk with commonly used methods and metrics, which include the calculations of market value of equity, duration of equity, and duration gap.

Regulatory Liquidity Requirements. The Bank is required to maintain a level of liquidity in accordance with certain Finance Agency guidance. Under these policies and guidelines, the Bank is required to maintain sufficient liquidity in an amount at least equal to its anticipated net cash outflows under two different scenarios. One scenario assumes that the Bank cannot access the capital markets for a period of 15 days and that, during that time, members do not renew any maturing, prepaid and called advances. The second scenario assumes that the Bank cannot access the capital markets for five days and during that period, an FHLBank will automatically renew maturing and called advances for all members except very large members, provided that the member is well-rated by its primary Federal regulator or its state regulator equivalent for insurance companies and is well-rated by the Bank's internal credit rating system. The Bank was in compliance with these requirements at June 30, 2018. Refer to the Liquidity and Funding Risk section in Item 7. of the Bank's 2017 Form 10-K for additional information.

Joint and Several Liability. Although the Bank is primarily liable for its portion of consolidated obligations (i.e., those issued on its behalf), the Bank is also jointly and severally liable with the other 10 FHLBanks for the payment of principal and interest on consolidated obligations of all the FHLBanks. The Finance Agency, in its discretion and notwithstanding any other provisions, may at any time order any FHLBank to make principal or interest payments due on any consolidated obligation, even in the absence of default by the primary obligor. To the extent that an FHLBank makes any payment on a consolidated obligation on behalf of another FHLBank, the paying FHLBank shall be entitled to reimbursement from the non-paying FHLBank, which has a corresponding obligation to reimburse the FHLBank to the extent of such assistance and other associated costs. However, if the Finance Agency determines that the non-paying FHLBank is unable to satisfy its obligations, then the Finance Agency may allocate the outstanding liability among the remaining FHLBanks on a pro rata basis in proportion to each FHLBank’s participation in all consolidated obligations outstanding, or on any other basis the Finance Agency may determine. Finance Agency regulations govern the issuance of debt on behalf of the FHLBanks and authorize the FHLBanks to issue consolidated obligations, through the OF as its agent. The Bank is not permitted to issue individual debt without Finance Agency approval. See Note 14 - Consolidated Obligations of the audited financial statements in Item 8. Financial Statements and Supplementary Financial Data in the Bank's 2017 Form 10-K for additional information.

Operational and Business Risks

Operational Risk. Operational Risk is defined as the risk of loss resulting from inadequate or failed internal processes, people, and systems, or from external events and encompasses risks related to housing mission-related activities, including activities associated with affordable housing programs or goals. The Bank considers various sources of risk of unexpected loss, including human error, fraud, unenforceability of legal contracts, deficiencies in internal controls and/or information systems, or damage from fire, theft, natural disaster or acts of terrorism. Generally, the category of operational risk includes loss exposures of a physical or procedural nature. Specifically, operational risk includes compliance, fraud, information/transaction, legal, cyber, vendor and people risk. The Bank has established operational risk policies and procedures to manage each of the specific operational risks.

Business Risk. Business risk is the risk of an adverse impact on the Bank’s profitability or financial or business strategies resulting from external factors that may occur in the short-term and/or long-term. This risk includes the potential for strategic business constraints to be imposed through regulatory, legislative or political changes. The Bank’s Risk Management Committee monitors economic indicators and the external environment in which the Bank operates and attempts to mitigate this risk through long-term strategic planning.

For additional information, on operating and business risks, see the "Operating and Business Risks" discussion in the Risk Management section of Item 7. in the Bank's 2017 Form 10-K.

Federal Home Loan Bank of Pittsburgh

Notes to Unaudited Financial Statements

Background Information

The Bank, a federally chartered corporation, is one of 11 district Federal Home Loan Banks (FHLBanks). The FHLBanks are government-sponsored enterprises (GSEs) that serve the public by increasing the availability of credit for residential mortgages and community development. The Bank provides a readily available, low-cost source of funds to its member institutions. The Bank is a cooperative, which means that current members own nearly all of the outstanding capital stock of the Bank. All holders of the Bank’s capital stock may, to the extent declared by the Board, receive dividends on their capital stock. Regulated financial depositories and insurance companies engaged in residential housing finance that maintain their principal place of business (as defined by Finance Agency regulation) in Delaware, Pennsylvania or West Virginia may apply for membership. Community Development Financial Institutions (CDFIs) which meet membership regulation standards are also eligible to become Bank members. State and local housing associates that meet certain statutory and regulatory criteria may also borrow from the Bank. While eligible to borrow, state and local housing associates are not members of the Bank and, as such, do not hold capital stock.

All members must purchase stock in the Bank. The amount of capital stock a member owns is based on membership requirements (membership asset value) and activity requirements (i.e., outstanding advances, letters of credit, and the principal balance of certain residential mortgage loans sold to the Bank). The Bank considers those members with capital stock outstanding in excess of 10% of total capital stock outstanding to be related parties. See Note 12 - Transactions with Related Parties for additional information.

The Federal Housing Finance Agency (Finance Agency) is the independent regulator of the FHLBanks. The mission of the Finance Agency is to ensure the FHLBanks operate in a safe and sound manner so they serve as a reliable source for liquidity and funding for housing finance and community investment. Each FHLBank operates as a separate entity with its own management, employees and board of directors. The Bank does not consolidate any off-balance sheet special-purpose entities or other conduits.

As provided by the Federal Home Loan Bank Act (FHLBank Act) or Finance Agency regulation, the Bank’s debt instruments, referred to as consolidated obligations, are joint and several obligations of all the FHLBanks and are the primary source of funds for the FHLBanks. These funds are primarily used to provide advances, purchase mortgages from members through the MPF Program and purchase certain investments. See Note 10 - Consolidated Obligations for additional information. The Office of Finance (OF) is a joint office of the FHLBanks established to facilitate the issuance and servicing of the consolidated obligations of the FHLBanks and to prepare the combined quarterly and annual financial reports of all the FHLBanks. Deposits, other borrowings, and capital stock issued to members provide other funds. The Bank primarily invests these funds in short-term investments to provide liquidity. The Bank also provides member institutions with correspondent services, such as wire transfer, safekeeping and settlement with the Federal Reserve.

The accounting and financial reporting policies of the Bank conform to U.S. Generally Accepted Accounting Principles (GAAP). Preparation of the unaudited financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses. Actual results could differ from those estimates. In addition, from time to time certain amounts in the prior period may be reclassified to conform to the current presentation. To the extent that any reclassifications were made, the reclassifications did not have a material impact on the Bank's financial statements. In the opinion of management, all normal recurring adjustments have been included for a fair statement of this interim financial information. These unaudited financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2017 included in the Bank's 2017 Form 10-K.

Note 1 – Changes in Accounting Principle and Recently Issued Accounting Standards and Interpretations

The Bank adopted the following new accounting standards during the six months ended June 30, 2018.



Standard	Description	Adoption Date and Transition	Effect on the Financial Statements or Other Significant Matters
Accounting Standards Update (ASU) 2017-07: Improving the presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost	This ASU requires entities to disaggregate the service cost component of net benefit cost from other components and present the other components outside of income from operations. It also requires that only the service cost component be eligible for capitalization.	The Bank adopted this ASU on January 1, 2018. The presentation of service costs separately was adopted on a retrospective basis. The limiting of capitalization to service costs was adopted on a prospective basis.	The adoption of this ASU did not materially impact the Bank’s results of operations. It resulted in an immaterial reclassification of other pension costs from "Compensation and benefits" to "Other operating" in the Statement of Income for all periods presented.
ASU 2016-15: Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments	This ASU is focused on reducing diversity in practice in the Statement of Cash Flows by providing clarification on eight classification issues.	The Bank adopted this ASU on January 1, 2018 on a modified retrospective basis.	The adoption of this ASU resulted in the Bank including interest paid on consolidated obligation discount notes in its "Interest paid" supplemental disclosure in the Statement of Cash Flows for all periods presented.
ASU 2016-01: Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities	This ASU amends certain requirements for accounting for the recognition and measurement of financial instruments. Most notably, this guidance revises the accounting for equity securities, financial instruments measured under the fair value option, and certain disclosure requirements for fair value of financial instruments.	The Bank adopted this ASU on January 1, 2018 on a modified retrospective basis.	The adoption of this ASU did not materially impact the Bank’s financial condition or results of operations. The Bank reclassified immaterial investments from "Trading securities" and "AFS securities" to "Other assets" in the Statement of Condition on January 1, 2018. The Bank also reflected the reduced disclosure requirements for financial instruments not recognized at fair value in the financial statements.
ASU 2014-09: Revenue from Contracts with Customers in conjunction with ASU 2017-05: Gains and Losses from the Derecognition of Nonfinancial Assets	ASU 2014-09 was issued to increase comparability across industries by providing a single, comprehensive revenue recognition model for all contracts with customers. It will require recognition of revenue to reflect the economics of the transaction and will require expanded disclosures regarding revenue recognition. ASU 2017-05 clarifies that the guidance in ASU 2014-09 should also be applied to the accounting for derecognition of nonfinancial assets, including sales of real estate assets such as REO.	This Bank adopted this ASU on January 1, 2018 on a modified retrospective basis.	The adoption of these ASUs did not impact the Bank’s financial condition or results of operations, as the majority of the Bank’s revenue is derived from financial instruments, which are excluded from the scope of this guidance.

Notes to Unaudited Financial Statements (continued)

The following table provides a brief description of recently issued accounting standards which may have an impact on the Bank.



Standard	Description	Effective Date and Transition	Effect on the Financial Statements or Other Significant Matters
ASU 2018-11: Targeted Improvements to Accounting for Leases	This ASU provides an additional transition method for the new leases standard, ASU 2016-02.	This ASU is effective for the Bank beginning January 1, 2019 and will be adopted on a modified retrospective basis as of the effective date.	The Bank will utilize the additional transition method to apply the new leases standard as of its effective date. Upon adoption, the Bank will not be required to restate comparative reporting periods.
ASU 2018-08: Contributions Received and Contributions Made	This ASU clarifies the distinction between exchange transactions and contributions, including whether a contribution is conditional.	This ASU is effective for the Bank beginning January 1, 2019 and will be adopted on a modified prospective basis.	The Bank is continuing to evaluate the impact of this ASU on its financial statements.
ASU 2017-12: Targeted Improvements to Accounting for Hedging Activities	This ASU makes amendments to the accounting for derivatives and hedging activities intended to better portray the economics of the transactions.	This ASU is effective for the Bank beginning January 1, 2019 and allows for early adoption. The guidance will be applied to existing hedging relationships as of the beginning of the year of adoption.	The Bank is continuing to evaluate the impact of this ASU on its financial statements. The Bank's hedging strategies, documentation, effectiveness testing, and presentation and disclosure may be impacted by this ASU.
ASU 2017-08: Premium Amortization on Purchased Callable Debt Securities	This ASU requires that the amortization period for premiums on certain purchased callable debt securities be shortened to the earliest call date, rather than contractual maturity.	This ASU is effective for the Bank beginning January 1, 2019 and will be adopted on a modified retrospective basis.	The Bank is continuing to evaluate the impact of this ASU on its financial statements. The Bank does not believe that the impact will be material to its financial condition or results of operations as it does not typically purchase callable debt securities at premiums.
ASU 2016-13: Financial Instruments - Credit Losses	This ASU makes substantial changes to the accounting for credit losses on certain financial instruments. It replaces the current incurred loss model with a new model based on lifetime expected credit losses, which the FASB believes will result in more timely recognition of credit losses.	This ASU is effective for the Bank no later than January 1, 2020 and will generally be adopted on a modified retrospective basis, with the exception of previously-OTTI AFS debt securities, for which the guidance will be applied prospectively.	The Bank is continuing to evaluate the impact of this ASU on its financial statements and will continue to monitor interpretations made by standard-setters and regulators. The Bank expects its allowance for credit losses on MPF loans to increase; however, the Bank does not currently have an estimate of the amount of the expected increase. The Bank has not yet determined the impact this standard will have on its private label MBS securities. The Bank will continue to evaluate the appropriateness of an allowance for credit losses on other specific elements of its financial statements.

Notes to Unaudited Financial Statements (continued)



Standard	Description	Effective Date and Transition	Effect on the Financial Statements or Other Significant Matters
ASU 2016-02: Leases	This ASU amends the accounting for leases. It will require lessees to recognize a right-of-use asset and lease liability for virtually all leases.	This ASU is effective for the Bank no later than January 1, 2019 and will be adopted on a modified retrospective basis as of the effective date.	The Bank is continuing to evaluate the impact of this ASU on its financial statements. Upon adoption, the Bank will increase its assets and liabilities for capitalized leases. The Bank’s most significant lease is its headquarters. Future minimum lease payments under current accounting standards are disclosed in Note 20 - Commitments and Contingencies in its 2017 Form 10-K. Substantially all of these payments represent the building lease.

Note 5 – Other-Than-Temporary Impairment (OTTI)

The Bank evaluates its individual AFS and HTM securities in an unrealized loss position for OTTI on a quarterly basis. The Bank assesses whether there is OTTI by performing an analysis to determine if any securities will incur a credit loss, the amount of which could be up to the difference between the security's amortized cost basis and its fair value, and records any difference in its Statement of Income. For information on the Bank’s accounting for OTTI, see Note 1 - Summary of Significant Accounting Policies to the audited financial statements in the Bank's 2017 Form 10-K. For information about how the Bank projects cash flows expected to be collected, see Note 7 - OTTI to the audited financial statements in the Bank’s 2017 Form 10-K.

The Bank performed a cash flow analysis using two third-party models to assess whether the amortized cost basis of its private label residential MBS will be recovered. During the second quarter of 2018, the OTTI Governance Committee developed a short-term housing price forecast using whole percentages with changes ranging from (8.0)% to 13.0% over the 12 month period beginning April 1, 2018. For the vast majority of markets the short-term forecast has changes from 2.0% to 7.0%. Thereafter, a unique path is projected for each geographic area based on an internally developed framework derived from historical data.

All of the Bank's other-than-temporarily impaired securities were classified as AFS as of June 30, 2018. The "Total OTTI securities" balances below summarize the Bank’s securities as of June 30, 2018 for which an OTTI has been recognized during the life of the security. The "Private label MBS with no OTTI" balances below represent AFS securities on which an OTTI was not taken. The sum of these two amounts reflects the total AFS private label MBS balance.

Notes:

⁽¹⁾ For the three months ended June 30, 2018 and 2017, additional OTTI credit losses for which an OTTI charge was previously recognized relate to all securities that were previously impaired prior to April 1 of the applicable year. For the six months ended June 30, 2018 and 2017, additional OTTI credit losses for which an OTTI charge was previously recognized relate to all securities that were previously impaired prior to January 1 of the applicable year.

All Other AFS and HTM Investments. At June 30, 2018, the Bank held certain securities in an unrealized loss position. These unrealized losses were considered to be temporary as the Bank expects to recover the entire amortized cost basis on the remaining securities in unrealized loss positions based on the creditworthiness of the underlying creditor, guarantor, or implicit government support, and the Bank neither intends to sell these securities nor considers it more likely than not that the Bank would be required to sell any such security before its anticipated recovery. As a result, the Bank did not consider any of these other investments to be other-than-temporarily impaired at June 30, 2018.

Note 6 – Advances

General Terms. The Bank offers fixed- and variable-rate advance products with different maturities, interest rates, payment characteristics and optionality. Fixed-rate advances generally have maturities ranging from one day to 30 years. Variable-rate advances generally have maturities ranging from less than 30 days to ten years, and the interest rates reset periodically at a fixed spread to LIBOR or other specified indices.

At June 30, 2018 and December 31, 2017, the Bank had advances outstanding, including AHP advances, with interest rates ranging from 0.83% to 7.40%. AHP subsidized advances have an interest rate of 5.50%.

The following table details the Bank’s advances portfolio by year of contractual maturity as of June 30, 2018 and December 31, 2017.

The Bank also offers convertible advances. Convertible advances allow the Bank to convert an advance from one interest rate structure to another. When issuing convertible advances, the Bank may purchase put options from a member that allow the Bank to convert the fixed-rate advance to a variable-rate advance at the current market rate or another structure after an agreed-upon lockout period. A convertible advance carries a lower interest rate than a comparable-maturity, fixed-rate advance without the conversion feature. In addition, the Bank offers certain advances to members that provide a member the right, based upon predetermined exercise dates, to prepay the advance prior to maturity without incurring prepayment or termination fees (returnable advances).

At June 30, 2018 and December 31, 2017, the Bank did not have any advances with embedded features that met the requirements to separate the embedded feature from the host contract and designate the embedded feature as a stand-alone derivative.

See Note 8 - Allowance for Credit Losses for information related to the Bank's credit risk on mortgage loans and allowance for credit losses.

Note 8 – Allowance for Credit Losses

The Bank has established an allowance methodology for each of the Bank’s portfolio segments: credit products, government-guaranteed or insured MPF loans held for portfolio, conventional MPF loans held for portfolio, and BOB loans.

Credit Products. The Bank manages its total credit exposure (TCE), which includes advances, letters of credit, advance commitments, and other credit product exposure, through an integrated approach. This approach generally requires a credit limit to be established for each borrower. This approach includes an ongoing review of each borrower’s financial condition in conjunction with the Bank's collateral and lending policies to limit risk of loss while balancing each borrower's need for a reliable source of funding. In addition, the Bank lends to its members in accordance with the FHLBank Act and Finance Agency regulations. Specifically, the FHLBank Act requires the Bank to obtain collateral to fully secure credit products. The estimated value of the collateral required to secure each member’s credit products is calculated by applying collateral weightings, or haircuts, to the value of the collateral. The Bank accepts cash, certain investment securities, residential mortgage loans, deposits, and other real estate related assets as collateral. In addition, Community Financial Institutions (CFIs) are eligible to utilize expanded statutory collateral provisions for small business, agriculture, and community development loans. The Bank’s capital stock owned by the borrowing member is pledged as secondary collateral. Collateral arrangements may vary depending upon borrower credit quality, financial condition and performance, borrowing capacity, and overall credit exposure to the borrower. The Bank can require additional or substitute collateral to help ensure that credit products continue to be secured by adequate collateral. Management of the Bank believes that these policies effectively manage the Bank’s credit risk from credit products.

Based upon the financial condition of the member, the Bank either allows a member to retain physical possession of the collateral assigned to the Bank or requires the member to specifically deliver physical possession or control of the collateral to the Bank or its custodians. However, regardless of the member's financial condition, the Bank always takes possession or control of securities used as collateral. The Bank perfects its security interest in all pledged collateral. The FHLBank Act affords any security interest granted to the Bank by a member (or an affiliate of a member) priority over the claims or rights of

Notes to Unaudited Financial Statements (continued)

any other party, except for claims or rights of a third party that would be otherwise entitled to priority under applicable law and that are held by a bona fide purchaser for value or by a secured party holding a prior perfected security interest.

Using a risk-based approach, the Bank considers the payment status, collateral types and concentration levels, and borrower’s financial condition to be indicators of credit quality on its credit products. At June 30, 2018 and December 31, 2017, the Bank had rights to collateral on a member-by-member basis with a value in excess of its outstanding extensions of credit.

The Bank continues to evaluate and, as necessary, make changes to its collateral guidelines based on current market conditions. At June 30, 2018 and December 31, 2017, the Bank did not have any credit products that were past due, on nonaccrual status, or considered impaired. In addition, the Bank did not have any credit products considered to be troubled debt restructurings (TDRs).

Based upon the collateral held as security, its credit extension policies, collateral policies, management’s credit analysis and the repayment history on credit products, the Bank has not incurred any credit losses on credit products since inception. Accordingly, the Bank has not recorded any allowance for credit losses for these products.

BOB Loans. Both the probability of default and loss given default are determined and used to estimate the allowance for credit losses on BOB loans. Loss given default is considered to be 100% due to the fact that the BOB program has no collateral or credit enhancements. The probability of default is based on the actual performance of the BOB program. The Bank considers BOB loans that are delinquent to be nonperforming assets. The allowance for credit losses on BOB loans was immaterial as of June 30, 2018 and December 31, 2017 and is not included in any of the tables that follow.

TDRs - BOB Loans. The Bank offers a BOB loan deferral, which the Bank considers a TDR. A deferred BOB loan is not required to pay principal or accrue interest for a period up to one year. The credit loss is measured by factoring expected shortfalls incurred as of the reporting date. BOB loan TDRs are not material to the Bank’s financial condition, results of operations, or cash flows.

Mortgage Loans - Government-Guaranteed or Insured. The Bank invests in government-guaranteed or insured fixed-rate mortgage loans secured by one-to-four family residential properties. Government-guaranteed mortgage loans are those insured or guaranteed by the Federal Housing Administration (FHA), Department of Veterans Affairs (VA), the Rural Housing Service (RHS) of the Department of Agriculture and/or by Housing and Urban Development (HUD). Any losses from such loans are expected to be recovered from those entities. If not, losses from such loans must be contractually absorbed by the servicers. Therefore, there is no allowance for credit losses on government-guaranteed or insured mortgage loans.

Mortgage Loans - Conventional MPF. The allowances for conventional loans are determined by analyses that include consideration of various data observations such as past performance, current performance, loan portfolio characteristics, collateral-related characteristics, industry data, and prevailing economic conditions. The measurement of the allowance for credit losses includes: (1) reviewing all residential mortgage loans at the individual master commitment level; (2) reviewing specifically identified collateral-dependent loans for impairment; and/or (3) reviewing homogeneous pools of residential mortgage loans.

The Bank’s allowance for credit losses takes into consideration the credit enhancement (CE) associated with conventional mortgage loans under the MPF Program. Specifically, the determination of the allowance generally considers expected Primary Mortgage Insurance (PMI), Supplemental Mortgage Insurance (SMI), and other CE amounts. Any incurred losses that are expected to be recovered from the CE reduce the Bank’s allowance for credit losses.

For conventional MPF loans, credit losses that are not fully covered by PMI are allocated to the Bank up to an agreed-upon amount, referred to as the first loss account (FLA). The FLA functions as a tracking mechanism for determining the point after which the participating financial institution (PFI) is required to cover losses. The Bank pays the PFI a fee, a portion of which may be based on the credit performance of the mortgage loans, in exchange for absorbing the second layer of losses up to an agreed-upon CE amount. The CE amount may be a direct obligation of the PFI and/or an SMI policy paid for by the PFI, and may include performance-based fees which can be withheld to cover losses allocated to the Bank (referred to as recaptured CE fees). The PFI is required to pledge collateral to secure any portion of its CE amount that is a direct obligation. A receivable which is assessed for collectability is generally established for losses expected to be recovered by withholding CE fees. Estimated losses exceeding the CE, if any, are incurred by the Bank. At June 30, 2018 and December 31, 2017, the MPF exposure under the FLA was $27.7 million and $26.3 million, respectively. The Bank records CE fees paid to PFIs as a reduction to mortgage loan interest income. The Bank incurred CE fees of $1.1 million and $0.9 million for the second quarter 2018 and 2017, and $2.2 million and $1.8 million for the six months ended June 30, 2018 and 2017, respectively.

Notes to Unaudited Financial Statements (continued)

Individually Evaluated Mortgage Loans. The Bank evaluates certain conventional mortgage loans for impairment individually. This includes impaired loans considered collateral-dependent loans where repayment is expected to be provided by the sale of the underlying property, which primarily consists of MPF loans that are 180 days or more delinquent, TDRs and other loans where the borrower has filed for bankruptcy.

The estimated credit losses on impaired collateral-dependent loans are separately determined because sufficient information exists to make a reasonable estimate of the inherent loss for such loans on an individual basis. The incurred loss on each loan is equal to the difference between the carrying value of the loan and the estimated fair value of the collateral less estimated selling costs and recovery through PMI. The estimated fair value is determined based on a value provided by a third party's retail-based Automated Valuation Model (AVM). The Bank adjusts the AVM based on the amount it has historically received on liquidations. The resulting loss is reduced by available CE. The estimated credit loss on individually evaluated MPF loans is charged-off against the reserve. However, if the estimated loss can be recovered through CE, a receivable is established, resulting in a net charge-off. The CE receivable is evaluated for collectibility, and a reserve, included as part of the allowance for credit losses, is established if required.

Collectively Evaluated Mortgage Loans. For the remainder of the portfolio, the Bank evaluates the homogeneous mortgage loan portfolio collectively for impairment. The allowance for credit loss methodology for mortgage loans considers loan pool specific attribute data, applies loss severities and incorporates the CEs of the MPF Program and PMI. The probability of default and loss given default are based on the actual 12-month historical performance of the Bank’s mortgage loans. Actual probability of default was determined by applying migration analysis to categories of mortgage loans (current, 30 days past due, 60 days past due, and 90 days past due). Actual loss given default was determined based on realized losses incurred on the sale of mortgage loan collateral over the previous 12 months. The resulting estimated losses are reduced by the CEs the Bank expects to be eligible to receive. The CEs are contractually set and calculated by a master commitment agreement between the Bank and the PFI. Losses in excess of the CEs are incurred by the Bank.

TDRs - Mortgage Loans - Conventional MPF. TDRs are considered to have occurred when a concession is granted to the debtor that would not have been considered had it not been for economic or legal reasons related to the debtor's financial difficulties. The Bank offers a loan modification program for its MPF Program. The loans modified under this program are considered TDRs. The Bank also considers a TDR to have occurred when a borrower files for Chapter 7 bankruptcy, the bankruptcy court discharges the borrower’s obligation, and the borrower does not reaffirm the debt. The recorded investment in mortgage loans classified as TDRs was $10.6 million and $11.1 million as of June 30, 2018 and December 31, 2017, respectively. The financial amounts related to TDRs are not material to the Bank’s financial condition, results of operations, or cash flows.

Real Estate Owned (REO). The Bank had $3.3 million and $3.9 million of REO reported in Other assets on the Statement of Condition at June 30, 2018 and December 31, 2017, respectively.

Purchases, Sales and Reclassifications. During the six months ended June 30, 2018 and 2017, there were no significant purchases or sales of financing receivables. Furthermore, none of the financing receivables were reclassified to held-for-sale.

Note 9 – Derivatives and Hedging Activities

Nature of Business Activity. The Bank is exposed to interest rate risk primarily from the effect of interest rate changes on its interest-earning assets and interest-bearing liabilities that finance these assets. The goal of the Bank's interest rate risk management strategy is not to eliminate interest rate risk but to manage it within appropriate limits. To mitigate the risk of loss, the Bank has established policies and procedures that include guidelines on the amount of exposure to interest rate changes it is willing to accept. In addition, the Bank monitors the risk to its interest income, net interest margin and average maturity of interest-earning assets and interest-bearing liabilities. For additional information on the Bank's derivative transactions, see Note 11 - Derivatives and Hedging Activities to the audited financial statements in the Bank's 2017 Form 10-K.

Derivative transactions may be executed either with a counterparty (referred to as uncleared derivatives) or cleared through a Futures Commission Merchant (i.e., clearing agent) with a Derivatives Clearing Organization (referred to as cleared derivatives). Once a derivative transaction has been accepted for clearing by a Derivative Clearing Organization (Clearing House), the executing counterparty is replaced with the Clearing House. The Bank is not a derivatives dealer and does not trade derivatives for short-term profit. The Bank transacts uncleared derivatives with large banks and major broker-dealers. Some of these banks and broker-dealers or their affiliates buy, sell, and distribute consolidated obligations.

Financial Statement Effect and Additional Financial Information. The following tables summarize the notional amount and fair value of derivative instruments and total derivatives assets and liabilities.

Note:

These amounts do not include $(1.1) million and $(0.9) million for the second quarter of 2018 and 2017, respectively, and $(1.7) million and $(1.6) million for the six months ended June 30, 2018 and 2017, respectively, of amortization/accretion of the basis adjustment related to discontinued fair value hedging relationships.

The Bank had no active cash flow hedging relationships during the first six months of 2018 or 2017.

Managing Credit Risk on Derivatives. The Bank is subject to credit risk due to the risk of nonperformance by counterparties to its derivative transactions. The Bank manages counterparty credit risk through credit analysis, collateral requirements, and adherence to the requirements set forth in its policies, U.S. Commodity Futures Trading Commission regulations, and Finance Agency regulations.

Uncleared Derivatives. For uncleared derivatives, the degree of credit risk depends on the extent to which netting arrangements are included in such contracts to mitigate the risk. The Bank requires collateral agreements with collateral delivery thresholds on all uncleared derivatives.

Notes to Unaudited Financial Statements (continued)

Generally, the Bank is subject to certain ISDA agreements for uncleared derivatives that require the Bank to post additional collateral with its counterparties if there is deterioration in the Bank's credit rating and the net liability position exceeds the relevant threshold. If the Bank’s credit rating were to be lowered by a major credit rating agency, the Bank would be required to deliver additional collateral on uncleared derivative instruments in net liability positions, unless the collateral delivery threshold is set to zero. The aggregate fair value of all uncleared derivative instruments with credit-risk related contingent features that that require the Bank to deliver additional collateral due to a credit downgrade and were in a net liability position (before cash collateral and related accrued interest) at June 30, 2018 was $11.0 million for which the Bank has posted cash collateral of $2.7 million. If the Bank’s credit rating had been lowered one notch (i.e., from its current rating to the next lower rating), the Bank would have been required to deliver up to an additional $6.7 million of collateral to its derivative counterparties at June 30, 2018.

Cleared Derivatives. For cleared derivatives, Derivative Clearing Organizations (Clearing Houses) are the Bank's counterparties. The Clearing House notifies the clearing agent of the required initial and variation margin. The requirement that the Bank post initial margin and exchange variation margin settlement payments through the clearing agent, which notifies the Bank on behalf of the Clearing Houses, exposes the Bank to institutional credit risk in the event that the clearing agent or the Clearing Houses fail to meet their respective obligations. The use of cleared derivatives is intended to mitigate credit risk exposure through the use of a central counterparty instead of individual counterparties. Collateral postings and variation margin settlement payments are made daily, through a clearing agent, for changes in the value of cleared derivatives. Initial margin is the amount calculated based on anticipated exposure to future changes in the value of a swap and protects the Clearing Houses from market risk in the event of default by one of their respective clearing agents. Variation margin is paid daily to settle the exposure arising from changes in the market value of the position. The Bank uses CME Clearing as the Clearing House for all cleared derivative transactions. Variation margin payments are characterized as daily settlement payments, rather than collateral. Initial margin is considered cash collateral.

Based on credit analyses and collateral requirements, the Bank does not anticipate credit losses related to its derivative agreements. See Note 13 - Estimated Fair Values for discussion regarding the Bank's fair value methodology for derivative assets and liabilities, including an evaluation of the potential for the fair value of these instruments to be affected by counterparty credit risk.

For cleared derivatives, the Clearing House determines initial margin requirements and generally credit ratings are not factored into the initial margin. However, clearing agents may require additional initial margin to be posted based on credit considerations, including but not limited to credit rating downgrades. The Bank was not required by its clearing agents to post additional initial margin at June 30, 2018.

Offsetting of Derivative Assets and Derivative Liabilities. When it has met the netting requirements, the Bank presents derivative instruments, related cash collateral received or pledged, and associated accrued interest on a net basis by clearing agent and/or by counterparty. The Bank has analyzed the enforceability of offsetting rights incorporated in its cleared derivative transactions and determined that the exercise of those offsetting rights by a non-defaulting party under these transactions should be upheld under applicable law upon an event of default including a bankruptcy, insolvency or similar proceeding involving the Clearing Houses or the Bank’s clearing agent, or both. Based on this analysis, the Bank nets derivative fair values on all of its transactions through a particular clearing agent with a particular Clearing House (including settled variation margin) into one net asset or net liability exposure. Initial margin posted to the clearing house is presented as a derivative asset.

Notes to Unaudited Financial Statements (continued)

Gross recognized amounts do not include the related collateral received from or pledged to counterparties.

Note 10 – Consolidated Obligations

Consolidated obligations consist of consolidated bonds and consolidated discount notes. The FHLBanks issue consolidated obligations through the OF as their agent. In connection with each debt issuance, each FHLBank specifies the amount of debt it wants to have issued on its behalf. The Bank records as a liability its specific portion of consolidated obligations for which it is the primary obligor.

Although the Bank is primarily liable for its portion of consolidated obligations, the Bank is also jointly and severally liable with the other ten FHLBanks for the payment of principal and interest on all consolidated obligations of each of the FHLBanks. The Finance Agency, at its discretion, may require any FHLBank to make principal or interest payments due on any consolidated obligations whether or not the consolidated obligation represents a primary liability of such FHLBank.

Although an FHLBank has never paid the principal or interest payments due on a consolidated obligation on behalf of another FHLBank, if one FHLBank is required to make such payments, Finance Agency regulations provide that the paying FHLBank is entitled to reimbursement from the non-complying FHLBank for any payments made on its behalf and other associated costs including interest to be determined by the Finance Agency. If the Finance Agency determines that the non-complying FHLBank is unable to satisfy its repayment obligations, then the Finance Agency may allocate the outstanding liabilities of the non-complying FHLBank among the remaining FHLBanks on a pro rata basis in proportion to each FHLBank’s participation in all consolidated obligations outstanding. However, the Finance Agency reserves the right to allocate the outstanding liabilities for the consolidated obligations among the FHLBanks in any other manner it may determine to ensure that the FHLBanks operate in a safe and sound manner. The par amounts of the FHLBanks’ outstanding consolidated obligations were $1,059.9 billion and $1,034.3 billion at June 30, 2018 and December 31, 2017, respectively.

Additional detailed information regarding consolidated obligations including general terms and interest rate payment terms can be found in Note 14 to the audited financial statements in the Bank's 2017 Form 10-K.

Note 11 – Capital

The Bank is subject to three capital requirements under its current Capital Plan Structure and the Finance Agency rules and regulations: (1) risk-based capital; (2) total regulatory capital; and (3) leverage capital. Regulatory capital does not include AOCI, but does include mandatorily redeemable capital stock. See details regarding these requirements and the Bank’s Capital Plan in Note 16 to the audited financial statements in the Bank’s 2017 Form 10-K. At June 30, 2018, the Bank was in compliance with all regulatory capital requirements.

The Bank has two subclasses of capital stock: B1 membership stock and B2 activity stock. The Bank had $0.4 billion and $3.6 billion in B1 membership stock and B2 activity stock, respectively, at June 30, 2018. The Bank had $0.4 billion and $3.3 billion in B1 membership stock and B2 activity stock, respectively, at December 31, 2017.

The following table demonstrates the Bank’s compliance with the regulatory capital requirements at June 30, 2018 and December 31, 2017.

When the Finance Agency implemented the prompt corrective action provisions of the Housing and Economic Recovery Act of 2008 (Housing Act), it established four capital classifications for the FHLBanks: adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. On June 7, 2018, the Bank received final notification from the Finance Agency that it was considered "adequately capitalized" for the quarter ended March 31, 2018. As of the date of this filing, the Bank has not received final notice from the Finance Agency regarding its capital classification for the quarter ended June 30, 2018.

Capital Concentrations. The following tables present member holdings of 10% or more of the Bank’s total capital stock, including mandatorily redeemable capital stock, outstanding as of June 30, 2018 and December 31, 2017.

Mandatorily Redeemable Capital Stock. The Bank is a cooperative whose member financial institutions and former members own all of the relevant Bank's issued and outstanding capital stock. Shares cannot be purchased or sold except between the Bank and its members at the shares' par value of $100, as mandated by the Bank's capital plan.

At June 30, 2018 and December 31, 2017, the Bank had $4.5 million and $5.1 million, respectively, in capital stock subject to mandatory redemption with payment subject to a five-year waiting period and the Bank meeting its minimum regulatory

capital requirements. Estimated dividends on mandatorily redeemable capital stock recorded as interest expense were immaterial during the three and six months ended June 30, 2018 and 2017.

The following table provides the related dollar amounts for activities recorded in mandatorily redeemable capital stock during the six months ended June 30, 2018 and 2017.

As of June 30, 2018, the total mandatorily redeemable capital stock reflected the balance for five institutions. Four institutions were merged out of district and are considered to be non-members. One other institution has notified the Bank of its intention to voluntarily redeem its capital stock and withdraw from membership. This institution will continue to be a member of the Bank until the withdrawal period is completed.

The following table shows the amount of mandatorily redeemable capital stock by contractual year of redemption at June 30, 2018 and December 31, 2017.

Under the terms of the Bank’s Capital Plan, membership capital stock is redeemable five years from the date of membership termination or withdrawal notice from the member. If the membership is terminated due to a merger or consolidation, the membership capital stock is deemed to be excess stock and is repurchased. The activity capital stock (i.e., supporting advances, letters of credit and MPF) relating to termination, withdrawal, mergers or consolidation is recalculated based on the underlying activity. Any excess activity capital stock is repurchased on an ongoing basis as part of the Bank’s excess stock repurchase program that is in effect at the time. Therefore, the redemption period could be less than five years if the stock becomes excess stock. However, the redemption period could extend beyond five years if the underlying activity is still outstanding.

Dividends and Retained Earnings. Each FHLBank is required to contribute 20% of its net income each quarter to a restricted retained earnings (RRE) account until the balance of that account equals at least 1% of that FHLBank's average balance of outstanding consolidated obligations for the previous quarter. These RRE will not be available to pay dividends. At June 30, 2018, retained earnings were $1,215.7 million, including $899.1 million of unrestricted retained earnings and $316.6 million of RRE.

The Finance Agency has issued regulatory guidance to the FHLBanks relating to capital management and retained earnings. The guidance directs each FHLBank to assess, at least annually, the adequacy of its retained earnings with consideration given to future possible financial and economic scenarios. The guidance also outlines the considerations that each FHLBank should undertake in assessing the adequacy of the Bank’s retained earnings. The Bank’s retained earnings policy and capital adequacy metric utilize this guidance.

Notes to Unaudited Financial Statements (continued)

Dividends paid by the Bank are subject to Board approval and may be paid in either capital stock or cash; historically, the Bank has paid cash dividends only. Dividends are based on stockholders' average balances for the previous quarter. Dividends paid through the first and second quarters of 2018 and 2017 are presented in the table below.

From time to time, the Bank may borrow from or lend to other FHLBanks on a short-term uncollateralized basis. During the six months ended June 30, 2018, there was no borrowing or lending activity between the Bank and other FHLBanks. During the six months ended June 30, 2017, the total amount borrowed from and repaid to other FHLBanks was $400.0 million.

Subject to mutually agreed upon terms, on occasion, an FHLBank may transfer at fair value its primary debt obligations to another FHLBank, which becomes the primary obligor on the transferred debt upon completion of the transfer. During the six months ended June 30, 2018 and 2017, there were no transfers of debt between the Bank and another FHLBank.

Notes to Unaudited Financial Statements (continued)

From time to time, a member of one FHLBank may be acquired by a member of another FHLBank. When such an acquisition occurs, the two FHLBanks may agree to transfer at fair value the loans of the acquired member to the FHLBank of the surviving member. The FHLBanks may also agree to the purchase and sale of any related hedging instrument. The Bank had no such activity during the six months ended June 30, 2018 and 2017.

Additional discussions regarding related party transactions can be found in Note 18 to the audited financial statements in the Bank's 2017 Form 10-K.

Note 13 – Estimated Fair Values

Fair value amounts have been determined by the Bank using available market information and appropriate valuation methods. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., an exit price). These estimates are based on recent market data and other pertinent information available to the Bank at June 30, 2018 and December 31, 2017. Although the management of the Bank believes that the valuation methods are appropriate and provide a reasonable determination of the fair value of these financial instruments, there are inherent limitations in any valuation technique. Therefore, these fair values are not necessarily equal to the amounts that would be realized in current market transactions, although they do reflect the Bank’s judgment of how a market participant would estimate the fair values.

The carrying value and estimated fair value of the Bank’s financial instruments at June 30, 2018 and December 31, 2017 are presented in the table below.

⁽²⁾Based on the fair value of the related collateral held, the securities purchased under agreements to resell were fully collateralized for the periods presented. There were no offsetting liabilities related to these securities at June 30, 2018 and December 31, 2017. These instruments’ maturity term is overnight.

⁽³⁾ The estimated fair value amount for the mandatorily redeemable capital stock line item includes accrued dividend interest; this amount is excluded from the estimated fair value for the accrued interest payable line item.

⁽⁴⁾ To conform with current presentation, $11.2 million in variation margin received on cleared derivatives has been allocated to the individual derivative instruments as of December 31, 2017. Previously, this amount was included with Netting Adjustments and Cash Collateral.

Fair Value Hierarchy. The fair value hierarchy is used to prioritize the inputs used to measure fair value by maximizing the use of observable inputs. The inputs are evaluated and an overall level for the fair value measurement is determined. This overall level is an indication of the market observability of the fair value measurement for the asset or liability.

The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels:

Level 1 Inputs - Quoted prices (unadjusted) for identical assets or liabilities in an active market that the reporting entity can access on the measurement date.

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

Level 3 Inputs - Unobservable inputs for the asset or liability.

Notes to Unaudited Financial Statements (continued)

The Bank reviews its fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation inputs may result in a reclassification of certain assets or liabilities. These reclassifications are reported as transfers in/out as of the beginning of the quarter in which the changes occur. There were no such transfers during the six months ended June 30, 2018 and 2017.

Summary of Valuation Methodologies and Primary Inputs

The valuation methodologies and primary inputs used to develop the measurement of fair value for assets and liabilities that are measured at fair value on a recurring or nonrecurring basis in the Statement of Condition are listed below.

Investment Securities – non-MBS. The Bank uses either the income or market approach to determine the estimated fair value of non-MBS investment securities.

For instruments that use the income approach, the significant inputs include a market-observable interest rate curve and a discount spread, if applicable. The market-observable interest rate curves and the related instrument types are as follows:

•Treasury curve: U.S. Treasury obligations

•LIBOR Swap curve: certificates of deposit

•CO curve: GSE and other U.S. obligations

The Bank uses a market approach for its state and local agency bonds. The Bank obtains prices from multiple designated third-party vendors when available, and the default price is the average of the prices obtained. Otherwise, the approach is generally consistent with the approach outlined below for Investment Securities - MBS.

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

During the year, the Bank conducts reviews of its pricing vendors to enhance its understanding of the vendors' pricing processes, methodologies and control procedures. To the extent available, the Bank also reviews the vendors' independent auditors' reports regarding the internal controls over their valuation processes.

The Bank's valuation technique first requires the establishment of a median price for each security. All prices that are within a specified tolerance threshold of the median price are included in the cluster of prices that are averaged to compute a default price. Prices that are outside the threshold (outliers) are subject to further analysis (including, but not limited to, comparison to prices provided by an additional third-party valuation service, prices for similar securities, and/or non-binding dealer estimates) to determine if an outlier is a better estimate of fair value. If an outlier (or some other price identified in the analysis) is determined to be a better estimate of fair value, then the outlier (or the other price as appropriate) is used as the final price rather than the default price. If, on the other hand, the analysis confirms that an outlier (or outliers) is (are) in fact not representative of fair value and the default price is the best estimate, then the default price is used as the final price. In all cases, the final price is used to determine the fair value of the security. If all prices received for a security are outside the tolerance threshold level of the median price, then there is no default price, and the final price is determined by an evaluation of all outlier prices as described above.

As of June 30, 2018, for substantially all of its MBS, the Bank received a price from all of its vendors and for all but one security, the default price was the final price. For this security, an analysis was conducted and the Bank concluded that the outlier price was the best estimate of fair value. In addition, there were minimal outliers to evaluate. Based on the Bank's reviews of the pricing methods including inputs and controls employed by the third-party pricing vendors and the relative lack of dispersion among the vendor prices (or, in those instances in which there were outliers or significant yield variances, the Bank's additional analyses), the Bank believes the final prices are representative of the prices that would have been received if the assets had been sold at the measurement date (i.e., exit prices) and further that the fair value measurements are classified appropriately in the fair value hierarchy. There continues to be unobservable inputs and a lack of significant market activity for private label MBS; therefore, as of June 30, 2018, the Bank classified private label MBS as Level 3.

Derivative Assets/Liabilities. The Bank bases the fair values of derivatives with similar terms on market prices, when available. However, market prices do not exist for many types of derivative instruments. Consequently, fair values for these instruments are estimated using standard valuation techniques such as discounted cash flow analysis and comparisons to similar instruments. Estimates developed using these methods are highly subjective and require judgment regarding significant matters such as the amount and timing of future cash flows, volatility of interest rates and the selection of discount rates that appropriately reflect market and credit risks. In addition, the fair value estimates for these instruments include accrued interest receivable/payable which approximate their carrying values due to their short-term nature.

The discounted cash flow analysis used to determine the net present value of derivative instruments utilizes market-observable inputs (inputs that are actively quoted and can be validated to external sources). Inputs by class of derivative are as follows:

Interest-rate related:


•	Discount rate assumption. Overnight Index Swap (OIS) curve through contractual term.


•	Forward interest rate assumption. LIBOR Swap curve or OIS curve through contractual term.


•	Volatility assumption. Market-based expectations of future interest rate volatility implied from current market prices for similar options.

Mortgage delivery commitments:


•	To Be Announced (TBA) securities prices. Market-based prices of TBAs are determined by coupon class and expected term until settlement and a pricing adjustment reflective of the secondary mortgage market.

The Bank is subject to credit risk on uncleared derivatives transactions due to the potential nonperformance by the derivatives counterparties. To mitigate this risk, the Bank has entered into netting arrangements and security agreements that provide for delivery of collateral at specified levels. As a result, uncleared derivatives are recognized as collateralized-to-market and the fair value of uncleared derivatives excludes netting adjustments and collateral. The Bank has evaluated the potential for fair value adjustment due to uncleared counterparty credit risk and has concluded that no adjustments are necessary.

The Bank's credit risk exposure on cleared derivatives is mitigated by the substitution of a central counterparty for individual counterparties. In addition, the CME Clearing rulebook requires delivery of initial margin to offset future changes in value and daily delivery of variation margin to offset changes in market value. Variation margin payments are daily settlement payments rather than collateral. Initial margin continues to be treated as collateral and accounted for separately.

The fair values of derivatives are netted by clearing agent and/or by counterparty pursuant to the provisions of each of the Bank’s netting agreements. If these netted amounts are positive, they are classified as an asset and, if negative, as a liability.

Impaired Mortgage Loans Held for Portfolio and Real Estate Owned. The estimated fair values of impaired mortgage loans held for portfolio and real estate owned are determined based on values provided by a third party's retail-based AVM. The Bank adjusts the AVM value based on the amount it has historically received on liquidation.

Subjectivity of Estimates. Estimates of the fair value of financial assets and liabilities using the methods described above are highly subjective and require judgments regarding significant matters such as the amount and timing of future cash flows, prepayment speed assumptions, expected interest rate volatility, possible distributions of future interest rates used to value options, and the selection of discount rates that appropriately reflect market and credit risks. The use of different assumptions could have a material effect on the fair value estimates. These estimates are susceptible to material near term changes because they are made as of a specific point in time.

Fair Value Measurements. The following tables present, for each hierarchy level, the Bank’s assets and liabilities that are measured at fair value on a recurring or non-recurring basis on its Statement of Condition at June 30, 2018 and December 31, 2017. The Bank measures certain mortgage loans held for portfolio at fair value when a charge-off is recognized and subsequently when the fair value less costs to sell is lower than the carrying amount. Real estate owned is measured using fair value when the assets' fair value less costs to sell is lower than the carrying amount.

Level 3 Disclosures for all Assets and Liabilities That Are Measured at Fair Value on a Recurring Basis. The following table presents a reconciliation of all assets and liabilities that are measured at fair value on the Statement of Condition using significant unobservable inputs (Level 3) for the three and six months ended June 30, 2018 and 2017. For instruments carried at fair value, the Bank reviews the fair value hierarchy classifications each quarter. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in/out at fair value in the quarter in which the changes occur. Transfers are reported as of the beginning of the period. There were no Level 3 transfers during the first six months of 2018 or 2017.

Notes:

⁽¹⁾ Excludes approved requests to issue future standby letters of credit of $165.9 million and $44.1 million at June 30, 2018 and December 31, 2017, respectively.

⁽²⁾ Letters of credit in the amount of $2.9 billion and $2.2 billion at June 30, 2018 and December 31, 2017, respectively, have annual renewal language that, as long as both parties agree, permit the letter of credit to be renewed for an additional year with a maximum renewal period of approximately 5 years.

Commitments to Extend Credit on Standby Letters of Credit, Additional Advances and BOB Loans. Standby letters of credit are issued on behalf of members for a fee. A standby letter of credit is a financing arrangement between the Bank and its member. If the Bank is required to make payment for a beneficiary’s draw, these amounts are withdrawn from the member’s Demand Deposit Account (DDA). Any remaining amounts not covered by the withdrawal from the member’s DDA are converted into a collateralized overnight advance.

Unearned fees related to standby letters of credit are recorded in other liabilities and had a balance of $4.0 million and $3.9 million as of June 30, 2018 and December 31, 2017, respectively. The Bank monitors the creditworthiness of its standby letters of credit based on an evaluation of the member. The Bank has established parameters for the review, assessment, monitoring and measurement of credit risk related to these standby letters of credit.

Based on management’s credit analyses, collateral requirements, and adherence to the requirements set forth in Bank policy and Finance Agency regulations, the Bank has not recorded any additional liability on these commitments and standby letters of credit. Refer to Note 8 - Allowance for Credit Losses in this Form 10-Q. Excluding BOB, commitments and standby letters of credit are collateralized at the time of issuance. The Bank records a liability with respect to BOB commitments, which is reflected in Other liabilities on the Statement of Condition.

The Bank does not have any legally binding or unconditional unused lines of credit for advances at June 30, 2018 and December 31, 2017. However, within the Bank's Open RepoPlus advance product, there were conditional lines of credit outstanding of $9.2 billion and $8.0 billion at June 30, 2018 and December 31, 2017, respectively.

Commitments to Fund or Purchase Mortgage Loans. The Bank may enter into commitments that unconditionally obligate the Bank to purchase mortgage loans under the MPF Program. These delivery commitments are generally for periods not to exceed 60 days. Such commitments are recorded as derivatives.

Pledged Collateral. The Bank may pledge cash and securities, as collateral, related to derivatives. Refer to Note 9 - Derivatives and Hedging Activities in this Form 10-Q for additional information about the Bank's pledged collateral and other credit-risk-related contingent features.

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

Notes 6, 9, 10, 11, and 12 also discuss other commitments and contingencies.

Item 3: Quantitative and Qualitative Disclosures about Market Risk

See the Risk Management section in Part I, Item 2. Management’s Discussion and Analysis in this Form 10-Q.

Item 4: Controls and Procedures
