Fair Value Disclosures

The fair value amounts recorded on the Statements of Condition and presented in the related note disclosures have been determined by the FHLBank using available market information and the FHLBank's best judgment of appropriate valuation methods. The fair values reflect the FHLBank's judgment of how a market participant would estimate the fair values.

Fair Value Hierarchy. The FHLBank records trading securities, available-for-sale securities, derivative assets, derivative liabilities and certain Consolidated Obligation Bonds at fair value on a recurring basis. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The inputs are evaluated and an overall level for the measurement is determined. This overall level is an indication of how market observable the fair value measurement is. An entity must disclose the level within the fair value hierarchy in which the measurements are classified.

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; (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.

The FHLBank reviews the fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation inputs may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in/out at fair value as of the beginning of the quarter in which the changes occur. The FHLBank did not have any transfers of assets or liabilities recorded at fair value on a recurring basis during the three months ended March 31, 2013 or 2012.

Table 18.1 presents the carrying value, fair value, and fair value hierarchy of financial assets and liabilities of the FHLBank. These values do not represent an estimate of the overall market value of the FHLBank as a going concern, which would take into account future business opportunities and the net profitability of assets versus liabilities.

Summary of Valuation Methodologies and Primary Inputs.

Cash and due from banks: The fair value equals the carrying value.

Interest-bearing deposits: The fair value is determined based on each security's quoted prices, excluding accrued interest, as of the last business day of the period.

Securities purchased under agreements to resell: The fair value approximates the carrying value. Based on the fair value of the related collateral held, the securities purchased under agreements to resell were fully collateralized for the periods presented.

Federal funds sold: The fair value of overnight Federal funds sold approximates the carrying value. The fair value of term Federal funds sold is determined by calculating the present value of the expected future cash flows. The discount rates used in these calculations are the rates for Federal funds with similar terms, as approximated by adding an estimated current spread to the LIBOR Swap Curve for Federal funds with similar terms. The fair value excludes accrued interest.

Trading securities: The FHLBank's trading portfolio generally consists of mortgage-backed securities issued by Ginnie Mae. Quoted market prices in active markets are not available for these securities.

To value mortgage-backed security holdings, the FHLBank obtains prices from four designated third-party pricing vendors when available. The pricing vendors use various proprietary models to price mortgage-backed securities. 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. Because many mortgage-backed securities 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. Each pricing vendor has an established challenge process in place for all mortgage-backed security valuations, which facilitates resolution of potentially erroneous prices identified by the FHLBank.

The FHLBank has conducted reviews of the pricing methods employed by the third-party vendors, to confirm and further augment its understanding of the vendors' pricing processes, methodologies and control procedures for specific instruments.

The FHLBank's valuation technique first requires the establishment of a “median” price for each security. If four prices are received, the average of the middle two prices is the median price; if three prices are received, the middle price is the median price; if two prices are received, the average of the two prices is the median price; and if one price is received, it is the median price (and also the final price) subject to validation. 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.

All 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, non-binding dealer estimates, and/or use of an internal model that is deemed most appropriate) 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. Alternatively, if the analysis confirms that an outlier is 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.

Four vendor prices were received for most of the FHLBank's mortgage-backed security holdings and the final prices for those securities were computed by averaging the prices received. Based on the FHLBank's review of the pricing methods and controls employed by the third-party pricing vendors and the relative lack of dispersion among the vendor prices, the FHLBank believes its final prices result in reasonable estimates of fair value and further that the fair value measurements are classified appropriately in the fair value hierarchy.

Available-for-sale securities: The FHLBank's available-for-sale portfolio generally consists of certificates of deposit. Quoted market prices in active markets are not available for these securities. Therefore, the fair value is determined based on each security's indicative fair value obtained from a third-party vendor. The FHLBank performs several validation steps in order to verify the accuracy and reasonableness of these fair values. These steps may include, but are not limited to, a detailed review of instruments with significant periodic price changes and a derived fair value from an option-adjusted discounted cash flow methodology using market-observed inputs for the interest rate environment and similar instruments.

Held-to-maturity securities: The FHLBank's held-to-maturity portfolio generally consists of discount notes issued by Freddie Mac and/or Fannie Mae (non-mortgage-backed securities), and mortgage-backed securities. Quoted market prices are not available for these securities. The fair value for each individual mortgage-backed security is determined by using the third-party vendor approach described above. In general, in order to determine the fair value of its non-mortgage backed securities, the FHLBank can use either (a) an income approach based on a market-observable interest rate curve that may be adjusted for a spread, or (b) prices received from third-party pricing vendors. The income approach uses indicative fair values derived from a discounted cash flow methodology. The FHLBank believes that both methodologies result in fair values that are reasonable and similar in all material respects based on the nature of the financial instruments being measured.

For its discount notes issued by Freddie Mac, and/or Fannie Mae, the FHLBank determines the fair value using the income approach. The market-observable interest rate curve used by the FHLBank includes the U.S. Government Agency Fair Value Curve.
 
Advances: The FHLBank determines the fair values of Advances by calculating the present value of expected future cash flows from the Advances excluding accrued interest. The discount rates used in these calculations are the replacement rates for Advances with similar terms, as approximated either by adding an estimated current spread to the LIBOR Swap Curve or by using current indicative market yields, as indicated by the FHLBank's pricing methodologies for Advances with similar current terms. Advance pricing is determined based on the FHLBank's rates on Consolidated Obligations. In accordance with Finance Agency Regulations, Advances with a maturity and repricing period greater than six months require a prepayment fee sufficient to make the FHLBank financially indifferent to the borrower's decision to prepay the Advances. Therefore, the fair value of Advances does not assume prepayment risk.

For swapped option-based Advances, the fair value is determined (independently of the related derivative) by the discounted cash flow methodology based on the LIBOR Swap Curve and forward rates at period end adjusted for the estimated current spread on new swapped Advances to the swap curve. For swapped Advances with a conversion option, the conversion option is valued by taking into account the LIBOR Swap Curve and forward rates at period end and the market's expectations of future interest rate volatility implied from current market prices of similar options.

Mortgage loans held for portfolio, net: The fair values of performing mortgage loans are determined based on quoted market prices offered to approved members as indicated by the FHLBank's MPP pricing methodologies for mortgage loans with similar current terms excluding accrued interest. The quoted prices offered to members are based on Fannie Mae price indications on to-be-announced mortgage-backed securities and FHA price indications on government-guaranteed loans. The FHLBank then adjusts these indicative prices to account for particular features of the FHLBank's MPP that differ from the Fannie Mae and FHA securities. These features include, but may not be limited to the MPP's credit enhancements, and marketing adjustments that reflect the FHLBank's cooperative business model and preferences for particular kinds of loans and mortgage note rates. These quoted prices, however, can change rapidly based upon market conditions and are highly dependent upon the underlying prepayment assumptions. In order to determine the fair values, the loan amounts are also reduced for the FHLBank's estimate of expected net credit losses. The fair value of non-performing conventional mortgage loans are based on the estimated values of the underlying collateral or the present value of future cash flows and as such are classified as Level 3 in the fair value hierarchy.

Accrued interest receivable and payable: The fair value approximates the carrying value.

Derivative assets/liabilities: The FHLBank's derivative assets/liabilities generally consist of interest rate swaps, to-be-announced mortgage-backed securities (forward rate agreements), and mortgage delivery commitments. The FHLBank's interest rate swaps are not listed on an exchange. Therefore, the FHLBank determines the fair value of each individual interest rate swap using market value models that use readily observable market inputs as their basis (inputs that are actively quoted and can be validated to external sources). The FHLBank uses a mid-market pricing convention as a practical expedient for fair value measurements within a bid-ask spread. These models reflect the contractual terms of the interest rate swaps, including the period to maturity, as well as the significant inputs noted below. The fair value determination uses the standard valuation technique of discounted cash flow analysis.

The FHLBank performs several validation steps to verify the reasonableness of the fair value output generated by the primary market value model. In addition to an annual model validation, the FHLBank prepares a monthly reconciliation of the model's fair values to estimates of fair values provided by the derivative counterparties. The FHLBank believes these processes provide a reasonable basis for it to place continued reliance on the derivative fair values generated by the model.

The fair value of TBA mortgage-backed securities is based on independent indicative and/or quoted prices generated by market transactions involving comparable instruments. The FHLBank determines the fair value of mortgage delivery commitments using market prices from the TBA/mortgage-backed security market or TBA/Ginnie Mae market and adjustments noted below.

The FHLBank's discounted cash flow analysis uses market-observable inputs. Inputs, by class of derivative, are as follows:

Interest-rate swaps:
▪
Forward interest rate assumption. LIBOR Swap Curve;
▪
Discount rate assumption. Overnight Index Swap Curve; and
▪
Volatility assumption. Market-based expectations of future interest rate volatility implied from current market prices for similar options.

To-be-announced mortgage-backed securities:
▪
Market-based prices by coupon class and expected term until settlement.

Mortgage delivery commitments:
▪
TBA price. Market-based prices of TBAs by coupon class and expected term until settlement, adjusted to reflect the contractual terms of the mortgage delivery commitments, similar to the mortgage loans held for portfolio process. The adjustments to the market prices are market observable, or can be corroborated with observable market data.

The FHLBank is subject to credit risk in derivatives transactions due to potential nonperformance by its derivatives counterparties, all of which are highly-rated institutions. To mitigate this risk, the FHLBank has entered into master netting agreements with all of its derivative counterparties. In addition, to limit the FHLBank's net unsecured credit exposure to these counterparties, the FHLBank has entered into bilateral security agreements with all active derivatives dealer counterparties that provide for delivery of collateral at specified levels. The FHLBank has evaluated the potential for the fair value of the instruments to be impacted by counterparty credit risk and has determined that no adjustments were significant or necessary to the overall fair value measurements at March 31, 2013 or December 31, 2012.

The fair values of the FHLBank's derivatives include accrued interest receivable/payable and cash collateral remitted to/received from counterparties. The estimated fair values of the accrued interest receivable/payable and cash collateral approximate their carrying values due to their short-term nature. The fair values of derivatives are netted by counterparty pursuant to the provisions of the FHLBank's master netting agreements. If these netted amounts are positive, they are classified as an asset and if negative, they are classified as a liability.

Deposits: The FHLBank determines the fair values of FHLBank deposits with fixed rates by calculating the present value of expected future cash flows from the deposits and reducing this amount for accrued interest payable. The discount rates used in these calculations are the cost of deposits with similar terms.

Consolidated Obligations: The FHLBank determines the fair values of Discount Notes by calculating the present value of expected future cash flows from the Discount Notes excluding accrued interest. The discount rates used in these calculations are current replacement rates for Discount Notes with similar current terms, as approximated by adding an estimated current spread to the LIBOR Swap Curve. Each month's cash flow is discounted at that month's replacement rate.

The FHLBank determines the fair values of non-callable Consolidated Obligation Bonds (both unswapped and swapped) by calculating the present value of scheduled future cash flows from the bonds excluding accrued interest. Inputs used to determine fair value of these Consolidated Obligation Bonds are as follows:

▪
The discount rates used, which are estimated current market yields, as indicated by the Office of Finance, for bonds with similar current terms. 

The FHLBank determines the fair values of callable Consolidated Obligation Bonds (both unswapped and swapped) by calculating the present value of expected future cash flows from the bonds excluding accrued interest. The fair values are determined by the discounted cash flow methodology based on the following inputs for these Consolidated Obligations:

▪
LIBOR Swap Curve;
▪
Volatility assumption. Market-based expectations of future interest rate volatility implied from current market prices for similar options; and
▪
Spread adjustment. Represents an adjustment to the curve.
 
Adjustments may be necessary to reflect the 12 FHLBanks' credit quality when valuing Consolidated Obligation Bonds measured at fair value. Due to the joint and several liability for Consolidated Obligations, the FHLBank monitors its own creditworthiness and the creditworthiness of the other FHLBanks to determine whether any credit adjustments are necessary in its fair value measurement of Consolidated Obligation Bonds. No adjustments were considered necessary at March 31, 2013 or December 31, 2012.

Mandatorily redeemable capital stock: The fair value of capital stock subject to mandatory redemption is par value for the dates presented, as indicated by member contemporaneous purchases and sales at par value. FHLBank stock can only be acquired by members at par value and redeemed at par value. FHLBank stock is not traded and no market mechanism exists for the exchange of stock outside the cooperative structure. 

Commitments: The fair values of standby bond purchase agreements are based on the present value of the estimated fees taking into account the remaining terms of the agreements.

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

Fair Value Option. The fair value option provides an irrevocable option to elect fair value as an alternative measurement for selected financial assets, financial liabilities, unrecognized firm commitments, and written loan commitments not previously carried at fair value. It requires a company to display the fair value of those assets and liabilities for which it has chosen to use fair value on the face of the Statements of Condition. Fair value is used for both the initial and subsequent measurement of the designated assets, liabilities and commitments, with the changes in fair value recognized in net income. If elected, interest income and interest expense on Advances and Consolidated Bonds carried at fair value are recognized based solely on the contractual amount of interest due or unpaid and any transaction fees or costs are immediately recognized into other non-interest income or other non-interest expense. Additionally, concessions paid on Consolidated Obligations designated under the fair value option are expensed as incurred in other non-interest expense.

The FHLBank has elected the fair value option for certain Consolidated Obligation Bond transactions. The FHLBank elected the fair value option for these transactions so as to mitigate the income statement volatility that can arise when only the corresponding derivatives are marked at fair value in transactions that do not, or may not, meet hedge effectiveness requirements or otherwise qualify for hedge accounting (i.e., economic hedging transactions).

For instruments recorded under the fair value option, the related contractual interest income and contractual interest expense are recorded as part of net interest income on the Statement of Income. The remaining changes in fair value for instruments in which the fair value option has been elected are recorded as “Net gains (losses) on Consolidated Obligation Bonds held under fair value option” in the Statements of Income. The FHLBank has determined that no adjustments to the fair values of its instruments recorded under the fair value option for instrument-specific credit risk were necessary as of March 31, 2013 or December 31, 2012.

The following table reflects the difference between the aggregate unpaid principal balance outstanding and the aggregate fair value for Consolidated Bonds for which the fair value option has been elected.
