Asset and Liability Management and Market Risk
The rates of interest the Bank earns on its assets and pays on its liabilities are generally established contractually for a period of time. Fluctuations in interest rates have a significant impact not only upon our net income, but also upon the cash flows and market values of our assets and liabilities. Our results of operations, like those of other financial institutions, are impacted by changes in interest rates and the interest rate sensitivity of our interest-earning assets and interest-bearing liabilities. Risk associated with changes in interest rates on the earnings of the Bank and the market value of its financial assets and liabilities is known as interest rate risk. Interest rate risk is our most significant market risk, and our ability to adapt to changes in interest rates is known as interest rate risk management.
The general objective of our interest rate risk management program is to determine and manage an appropriate level of interest rate risk while maximizing net interest income in a manner consistent with our policy to manage, to the extent practicable, the exposure of net interest income to changes in market interest rates. The Board of Directors and Asset and Liability Management Committee ("ALCO") regularly review the Bank's interest rate risk exposure by forecasting the impact of hypothetical, alternative interest rate environments on net interest income and the market value of portfolio equity ("MVPE") at various dates. The MVPE is defined as the net of the present value of cash flows from existing assets, liabilities, and off-balance sheet instruments. The present values are determined based upon market conditions as of the date of the analysis, as well as in alternative interest rate environments providing potential changes in the MVPE under those alternative interest rate environments. Net interest income is projected in the same alternative interest rate environments with both a static balance sheet and management strategies considered. The MVPE and net interest income analyses are also conducted to estimate our sensitivity to rates for future time horizons based upon market conditions as of the date of the analysis. In addition to the interest rate environments presented below, management also reviews the impact of non-parallel rate shock scenarios on a quarterly basis. These scenarios consist of flattening and steepening the yield curve by changing short-term and long-term interest rates independent of each other, and simulating cash flows and determining valuations as a result of these hypothetical changes in interest rates to identify rate environments that pose the greatest risk to the Bank. This analysis helps management quantify the Bank's exposure to changes in the shape of the yield curve.
General assumptions used by management to evaluate the sensitivity of our financial performance to changes in interest rates presented in the tables below are utilized in, and set forth under, the gap table and related notes. Although management finds these assumptions reasonable, the interest rate sensitivity of our assets and liabilities and the estimated effects of changes in interest rates on our net interest income and MVPE indicated in the below tables could vary substantially if different assumptions were used or actual experience differs from these assumptions. To illustrate this point, the projected cumulative excess (deficiency) of interest-earning assets over interest-bearing liabilities within the next 12 months as a percent of total assets ("one-year gap") is also provided for an up 200 basis point scenario, as of September 30, 2022.
Qualitative Disclosure about Market Risk
Gap Table. The following gap table summarizes the anticipated maturities or repricing periods of the Bank's interest-earning assets and interest-bearing liabilities based on the information and assumptions set forth in the notes below. Cash flow projections for mortgage-related assets are calculated based in part on prepayment assumptions at current and projected interest rates. Prepayment projections are subjective in nature, involve uncertainties and assumptions and, therefore, cannot be determined with a high degree of accuracy. Although certain assets and liabilities may have similar maturities or periods to repricing, they may react differently to changes in market interest rates. Assumptions may not reflect how actual yields and costs respond to market interest rate changes. The interest rates on certain types of assets and liabilities may fluctuate in advance of changes in market interest rates, while interest rates on other types of assets and liabilities may lag behind changes in market interest rates. Certain assets, such as adjustable-rate loans, have features that restrict changes in interest rates on a short-term basis and over the life of the asset. In the event of a change in interest rates, prepayment and early withdrawal levels would likely deviate significantly from those assumed in calculating the gap table below. A positive gap generally means more cash flows from assets are expected to reprice than cash flows from liabilities and suggests in a rising rate environment, that earnings should increase. A negative gap generally means more cash flows from liabilities are expected to reprice than cash flows from assets and suggests, in a rising rate environment, that earnings should decrease.

(1) Adjustable-rate loans are included in the period in which the rate is next scheduled to adjust or in the period in which repayments are expected to occur, or prepayments are expected to be received, prior to their next rate adjustment, rather than in the period in which the loans are due. Fixed-rate loans are included in the periods in which they are scheduled to be repaid, based on scheduled amortization and prepayment assumptions. Balances are net of undisbursed amounts and deferred fees and exclude loans 90 or more days delinquent or in foreclosure.
(2) MBS reflect projected prepayments at amortized cost. All other securities are presented based on contractual maturities, term to call dates or pre-refunding dates as of September 30, 2022, at amortized cost.
(3) Although the Bank's checking, savings, and money market accounts are subject to immediate withdrawal, management considers a substantial amount of these accounts to be core deposits having significantly longer effective maturities. The decay rates (the assumed rates at which the balances of existing accounts decline) used on these accounts is based on assumptions developed from our actual experiences with these accounts. If all of the Bank's checking, savings, and money market accounts had been assumed to be subject to repricing within one year, interest-bearing liabilities which were estimated to mature or reprice within one year would have exceeded interest-earning assets with comparable characteristics by $4.01 billion, for a cumulative one-year gap of (41.7)% of total assets.
(4) Borrowings exclude deferred prepayment penalty costs. Included in this line item are $365.0 million of FHLB adjustable-rate advances tied to interest rate swaps. The repricing for these liabilities is projected to occur at the maturity date of each interest rate swap.
At September 30, 2022, the Bank's gap between the amount of interest-earning assets and interest-bearing liabilities projected to reprice within one year was $(1.14) billion, or (11.89)% of total assets, compared to $(664.1) million, or (6.9)% of total assets, at September 30, 2021. The change in the one-year gap amount was due primarily to a decrease in the amount of assets projected to reprice as higher interest rates resulted in lower prepayment projections on the Bank's mortgage-related assets.
49
The majority of interest-earning assets anticipated to reprice in the coming year are repayments and prepayments on one- to four-family loans and MBS, both of which include the option to prepay without a fee being paid by the contract holder. The amount of interest-bearing liabilities expected to reprice in a given period is not typically impacted significantly by changes in interest rates, because the Bank's borrowings and certificate of deposit portfolios have contractual maturities and generally cannot be terminated early without a prepayment penalty. If interest rates were to increase 200 basis points, as of September 30, 2022, the Bank's one-year gap is projected to be $(1.17) billion, or (12.1)% of total assets. The change in the gap compared to when there is no change in rates is due to lower anticipated net cash flows primarily due to lower repayments on mortgage-related assets in the higher interest rate environment. This compares to a one-year gap of $(1.29) billion, or (13.4)% of total assets, if interest rates were to have increased 200 basis points as of September 30, 2021.
Change in Net Interest Income. The Bank's net interest income projections are a reflection of the response to interest rates of the assets and liabilities that are expected to mature or reprice over the next year. Repricing occurs as a result of cash flows that are received or paid on assets or due on liabilities which would be replaced at then current market interest rates or on adjustable-rate products that reset during the next year. The Bank's borrowings and certificate of deposit portfolios have stated maturities and the cash flows related to the Bank's liabilities do not generally fluctuate as a result of changes in interest rates. Cash flows from mortgage-related assets and callable agency debentures can vary significantly as a result of changes in interest rates. As interest rates decrease, borrowers have an economic incentive to lower their cost of debt by refinancing or endorsing their mortgage to a lower interest rate. Similarly, agency debt issuers are more likely to exercise embedded call options for agency securities and issue new securities at a lower interest rate.
For each date presented in the following table, the estimated change in the Bank's net interest income is based on the indicated instantaneous, parallel and permanent change in interest rates. The change in each interest rate environment represents the difference between estimated net interest income in the 0 basis point interest rate environment ("base case," assumes the forward market and product interest rates implied by the yield curve are realized) and the estimated net interest income in each alternative interest rate environment (assumes market and product interest rates have a parallel shift in rates across all maturities by the indicated change in rates). Projected cash flows for each scenario are based upon varying prepayment assumptions to model likely customer behavior changes as market rates change. At September 30, 2021, multiple yields along the yield curve were less than one percent, so the -100 basis points and -200 basis points scenarios were not applicable. Estimations of net interest income used in preparing the table below were based upon the assumptions that the total composition of interest-earning assets and interest-bearing liabilities does not change materially and that any repricing of assets or liabilities occurs at anticipated product and market rates for the alternative rate environments as of the dates presented. The estimation of net interest income does not include any projected gains or losses related to the sale of loans or securities, or income derived from non-interest income sources, but does include the use of different prepayment assumptions in the alternative interest rate environments. It is important to consider that estimated changes in net interest income are for a cumulative four-quarter period. These do not reflect the earnings expectations of management.

The net interest income projection was lower in the base case scenario at September 30, 2022 compared to September 30, 2021 due to higher interest expense projections on the Bank's liabilities than interest income projections on the Bank's assets as a result of higher interest rates at September 30, 2022. This was driven primarily by a faster increase in the cost of liabilities during fiscal year 2022 compared to the rate of increase in asset yields. In the rising interest rate scenarios, the cost of liabilities is projected to continue to increase at a faster pace than asset yields, resulting in a projected decrease in net
50
interest income in these interest rate scenarios. This was not the case at September 30, 2021, as interest rates were lower than at September 30, 2022, resulting in more mortgage-related cash flows projected to reprice as interest rates increased.
In the decreasing interest rate scenarios at September 30, 2022, the net interest income projection remained relatively flat as the projected increase in mortgage-related assets repricing to lower interest rates was largely offset by liability cash flows repricing to lower interest rates as well.
Change in MVPE. Changes in the estimated market values of our financial assets and liabilities drive changes in estimates of MVPE. The market value of an asset or liability reflects the present value of all the projected cash flows over its remaining life, discounted at market interest rates. As interest rates rise, generally the market value for both financial assets and liabilities decrease. The opposite is generally true as interest rates fall. The MVPE represents the theoretical market value of capital that is calculated by netting the market value of assets, liabilities, and off-balance sheet instruments. If the market values of financial assets increase at a faster pace than the market values of financial liabilities, or if the market values of financial liabilities decrease at a faster pace than the market values of financial assets, the MVPE will increase. The market value of shorter term-to-maturity financial instruments is less sensitive to changes in interest rates than are longer term-to-maturity financial instruments. Because of this, the market values of our certificates of deposit (which generally have relatively shorter average lives) tend to display less sensitivity to changes in interest rates than do our mortgage-related assets (which generally have relatively longer average lives). The average life expected on our mortgage-related assets varies under different interest rate environments because borrowers have the ability to prepay their mortgage loans. Therefore, as interest rates decrease, the WAL of mortgage-related assets decrease as well. As interest rates increase, the WAL would be expected to increase, as well as increasing the sensitivity of these assets in higher rate environments.
The following table sets forth the estimated change in the MVPE for each date presented based on the indicated instantaneous, parallel, and permanent change in interest rates. The change in each interest rate environment represents the difference between the MVPE in the base case (assumes the forward market interest rates implied by the yield curve are realized) and the MVPE in each alternative interest rate environment (assumes market interest rates have a parallel shift in rates). Projected cash flows for each scenario are based upon varying prepayment assumptions to model likely customer behavior as market rates change. At September 30, 2021, multiple yields along the yield curve were less than one percent, so the -100 basis points and -200 basis points scenarios were not applicable. The estimations of the MVPE used in preparing the table below were based upon the assumptions that the total composition of interest-earning assets and interest-bearing liabilities does not change, that any repricing of assets or liabilities occurs at current product or market rates for the alternative rate environments as of the dates presented, and that different prepayment rates were used in each alternative interest rate environment. The estimated MVPE results from the valuation of cash flows from financial assets and liabilities over the anticipated lives of each for each interest rate environment. The table below presents the effects of the changes in interest rates on our assets and liabilities as they mature, repay, or reprice, as shown by the change in the MVPE for alternative interest rates.

The percentage change in the Bank's MVPE at September 30, 2022 and September 30, 2021 was negative in all rising interest rate scenarios. The negative impact to the Bank's MVPE was greater at September 30, 2022 compared to September 30, 2021 due primarily to an increase in the duration of the Bank's mortgage-related assets at September 30, 2022 compared to September 30, 2021. This was a result of higher interest rates at September 30, 2022. As interest rates increase, borrowers
51
have less economic incentive to refinance their mortgages and agency debt issuers have less economic incentive or opportunity to exercise their call options in order to issue new debt at lower interest rates, resulting in lower projected cash flows on these assets. As interest rates increase in the rising interest rate scenarios, repayments on mortgage-related assets are more likely to decrease and only be realized through significant changes in borrowers' lives such as divorce, death, job-related relocations, or other events as there is less economic incentive for borrowers to prepay their debt, resulting in an increase in the average life of mortgage-related assets. Similarly, call projections for the Bank's callable agency debentures decrease as interest rates rise, which results in cash flows related to these assets moving closer to the contractual maturity dates. The higher expected average lives of these assets increases the sensitivity of their market value to changes in interest rates.
In the decreasing interest rate scenarios at September 30, 2022, the Bank's MVPE increased due to a larger increase in the market value of the Bank's assets than the Bank's liabilities. This is because the Bank's mortgage-related assets continue to have a higher duration in these interest rate scenarios which results in greater sensitivity in market value as interest rates change.
The following table presents the weighted average yields/rates and WALs (in years), after applying prepayment, call assumptions, and decay rates for our interest-earning assets and interest-bearing liabilities as of September 30, 2022. Yields presented for interest-earning assets include the amortization of fees, costs, premiums and discounts, which are considered adjustments to the yield. The interest rate presented for term borrowings is the effective rate, which includes the impact of interest rate swaps and the amortization of deferred prepayment penalties resulting from FHLB advances previously prepaid. The WAL presented for term borrowings includes the effect of interest rate swaps.
