Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation - The Company has prepared the consolidated unaudited interim financial statements included in this report. All intercompany transactions and accounts have been eliminated in consolidation. The preparation of financial statements, in conformity with accounting principles generally accepted in the United States of America (“GAAP”), requires management to make estimates and assumptions that affect amounts reported in the financial statements. Actual results could differ from these estimates. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation are reflected in the interim financial statements. The information included in this Form 10-Q should be read in conjunction with the financial statements and related notes in the Company's 2022 Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on November 18, 2022 ("2022 Annual Financial Statements"). Interim results are not necessarily indicative of results for a full year.
Equity Securities | Equity Securities - The Company records equity securities within Other assets in its Consolidated Statements of Financial Condition. These equity investments are accounted for under different methods. •Low-income housing tax credit investments are accounted for under the proportional amortization method in accordance with Accounting Standards Update (“ASU”) 2014-01, Equity Method and Joint Ventures (Topic 323). •For other equity investments where the Company has significant influence, the Company applies the equity method of accounting, which adjusts the carrying value of the investment to recognize a proportionate share of the financial results of the investment entity, regardless of whether any distribution is made. Any adjustments to the fair value of these investments are recorded in Other income in the Consolidated Statements of Operations. •For other equity investments where neither ASU 2014-01 nor the equity method of accounting is applicable, the Company applies the fair value adjustment method of ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10). Any adjustments to the fair value of these investments are recorded in Other income in the Consolidated Statements of Operations. Fair value is determined by reference to readily determinable market values if applicable. Equity investments that do not have readily determinable fair values (non-marketable) are generally accounted for at cost minus impairment, if any, plus or minus changes resulting from observable transactions involving the same or similar investments from the same issuer, also referred to as the measurement alternative. Under the NAV expedient for fair value measurement, equity investments in qualified real estate funds can use the net asset value (“NAV”) determined by the fund as fair value for the investment. At June 30, 2023, equity investments held by the Company and recorded at NAV had a carrying amount of $35,088,000 and a remaining unfunded commitment of $8,273,000. These NAV based investments cannot be transferred without consent and we do not have redemption rights. Equity investments measured at NAV are not classified in the fair value hierarchy.
Allowance for Credit Losses (Loans Receivable, Held-to-Maturity and Available-for-Sale Debt Securities) | Allowance for Credit Losses (Loans Receivable) - The Company maintains an allowance for credit losses (“ACL”) for the expected credit losses of the loan portfolio as well as unfunded loan commitments. The amount of ACL is based on ongoing, quarterly assessments by management. The current expected credit losses ("CECL") methodology requires an estimate of the credit losses expected over the life of an exposure (or pool of exposures). The ACL consists of the allowance for loan losses and the reserve for unfunded commitments. The estimate of expected credit losses under the CECL methodology is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is generally the starting point for estimating expected credit losses. We then consider whether the historical loss experience should be adjusted for asset-specific risk characteristics or current conditions at the reporting date that did not exist over the period that historical experience was based for each loan type. Finally, we consider forecasts about future economic conditions or changes in collateral values that are reasonable and supportable. Portfolio segment is defined as the level at which an entity develops and documents a systematic methodology to determine its ACL. The Company has designated two loan portfolio segments: commercial loans and consumer loans. These loan portfolio segments are further disaggregated into classes, which represent loans of similar type, risk characteristics, and methods for monitoring and assessing credit risk. The commercial loan portfolio segment is disaggregated into five classes: multi-family, commercial real estate, commercial and industrial, construction, and land acquisition and development. The risk of loss for the commercial loan portfolio segment is generally most indicated by the credit risk rating assigned to each borrower. Commercial loan risk ratings are determined by experienced senior credit officers based on specific facts and circumstances and are subject to periodic review by an independent internal team of credit specialists. The consumer loan portfolio segment is disaggregated into five classes: single-family-residential mortgage, custom construction, consumer lot loans, home equity lines of credit, and other consumer. The risk of loss for the consumer loan portfolio segment is generally most indicated by delinquency status and general economic factors. Each commercial and consumer loan portfolio class may also be further segmented based on risk characteristics. For most of our loan portfolio classes, the historical loss experience is determined using a cohort methodology. This method pools loans into groups (“cohorts”) sharing similar risk characteristics and tracks each cohort’s net charge-offs over the lives of the loans to calculate a historical loss rate. The historical loss rates for each cohort are then averaged to calculate an overall historical loss rate which is applied to the current loan balance to arrive at the quantitative baseline portion of the allowance for credit losses for the respective loan portfolio class. For certain loan portfolio classes, the Company determined there was not sufficient historical loss information to calculate a meaningful historical loss rate using the cohort methodology. For any such loan portfolio class, the weighted-average remaining maturity (“WARM”) methodology is being utilized until sufficient historical loss data is obtained. The WARM method multiplies an average annual loss rate by the expected remaining life of the loan pool to arrive at the quantitative baseline portion of the allowance for credit losses for the respective loan portfolio class. The Company also considers qualitative adjustments to the historical loss rate for each loan portfolio class. The qualitative adjustments for each loan class consider the conditions over the period from which historical loss experience was based and are split into two components: 1) asset or class specific risk characteristics or current conditions at the reporting date related to portfolio credit quality, remaining payments, volume and nature, credit culture and management, business environment or other management factors and 2) a reasonable and supportable forecast of future economic conditions and collateral values. The Company performs a quarterly asset quality review which includes a review of forecasted gross charge-offs and recoveries, nonperforming assets, criticized loans, risk rating migration, delinquencies, etc. The asset quality review is performed by management and the results are used to consider a qualitative overlay to the quantitative baseline. The second qualitative adjustment noted above, economic conditions and collateral values, encompasses a one-year reasonable and supportable forecast period. The overlay adjustment for the reasonable and supportable forecast assumes an immediate reversion after the one-year forecast period to historical loss rates for the remaining life of the respective loan pool. When management deems it to be appropriate, the Company establishes a specific reserve for individually evaluated loans that do not share similar risk characteristics with the loans included in each respective loan pool. These individually evaluated loans are removed from their respective pools and typically represent collateral dependent loans but may also include other non-performing loans or troubled debt restructurings (“TDRs”). In addition, the Company individually evaluates “reasonably expected” TDRs, which are identified by the Company as a loan expected to be classified as a TDR within the next six months. Management judgment is utilized to make this determination. Allowance for Credit Losses (Held-to-Maturity Debt Securities) - For held-to-maturity (“HTM”) debt securities, the Company is required to utilize a CECL methodology to estimate expected credit losses. Substantially all of the Company’s HTM debt securities are issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government and have a long history of zero credit loss. See Note F "Fair Value Measurements" for more information about HTM debt securities. Allowance for Credit Losses (Available-for-Sale Debt Securities) - The impairment model for available-for-sale (“AFS”) debt securities differs from the CECL methodology applied for HTM debt securities because AFS debt securities are measured at fair value rather than amortized cost. For AFS debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis. If either criteria is met, the security’s amortized cost basis is written down to fair value through income. For AFS debt securities where neither of the criteria are met, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the credit rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited to the amount that the fair value is less than the amortized cost basis. Any remaining discount that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Changes in the allowance for credit losses are recorded as a provision for (or release of) credit losses. Losses are charged against the allowance when management believes the uncollectibility of an AFS security is confirmed or when either of the criteria regarding intent or requirement to sell is met.
Accrued Interest Receivable | Accrued Interest Receivable - The Company made the following elections regarding accrued interest receivable (“AIR”): •Presenting accrued interest receivable balances separately from their underlying instruments within the consolidated statements of financial condition. •Excluding accrued interest receivable that is included in the amortized cost of financing receivables from related disclosure requirements. •Continuing our policy to write off accrued interest receivable by reversing interest income in cases where the Company does not reasonably expect to receive payment. •Not measuring an allowance for credit losses for accrued interest receivable due to the Company’s policy of writing off uncollectible accrued interest receivable balances in a timely manner, as described above.
Non-Accrual and Collateral-Dependent Loans | Non-Accrual Loans - Loans are placed on non-accrual status when, in the judgment of management, the probability of collection of interest is deemed to be insufficient to warrant further accrual. When a loan is placed on non-accrual status, previously accrued but unpaid interest is deducted from interest income. The Bank does not accrue interest on loans 90 days or more past due, except for situations where principal and interest is considered collectible such as a loan with a guarantee. If payment is made on a loan so that the loan becomes less than 90 days past due, and the Bank expects full collection of principal and interest, the loan is returned to full accrual status. Any interest ultimately collected is credited to income in the period of recovery. A loan is charged-off when the loss is estimable and it is confirmed that the borrower is not expected to be able to meet contractual obligations. If a consumer loan is on non-accrual status before becoming a TDR it will stay on non-accrual status following restructuring until it has been performing for at least six months, at which point it may be moved to accrual status. If a loan is on accrual status before it becomes a TDR, and management concludes that full repayment is probable based on internal evaluation, it will remain on accrual status following restructuring. If the restructured consumer loan does not perform, it is placed on non-accrual status when it is 90 days delinquent. For commercial loans, six consecutive payments on newly restructured loan terms are required prior to returning the loan to accrual status. In some instances, after the required six consecutive payments are made, management will conclude that collection of the entire principal and interest due is still in doubt. In those instances, the loan will remain on non-accrual status. Collateral-Dependent Loans - A financial asset is considered collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. For all classes of loans and leases deemed collateral-dependent, the Company elected the practical expedient to estimate expected credit losses based on the collateral’s fair value less cost to sell. In most cases, the Company records a partial charge-off to reduce the loan’s carrying value to the collateral’s fair value less cost to sell. Substantially all of the collateral consists of various types of real estate including residential properties; commercial properties such as retail centers, office buildings, and lodging; agriculture land; and vacant land.
Off-balance-sheet credit exposures | Off-balance-sheet credit exposures - The only material off-balance-sheet credit exposures are unfunded loan commitments, which had a combined balance of $4,088,046,000 and $4,947,570,000 at June 30, 2023 and September 30, 2022, respectively. The reserve for unfunded commitments is recognized as a liability (included as other liabilities in "Accrued expenses and other liabilities" in the consolidated statements of financial condition), with adjustments to the reserve recognized through provision for credit losses in the consolidated statements of income. The reserve for unfunded commitments represents the expected lifetime credit losses on off-balance sheet obligations such as commitments to extend credit and standby letters of credit. However, a liability is not recognized for commitments that are unconditionally cancellable by the Company. The reserve for unfunded commitments is determined by estimating future draws, including the effects of risk mitigation actions, and applying the expected loss rates on those draws. Loss rates are estimated by utilizing the same loss rates calculated for the allowance for credit losses related to the respective loan portfolio class, adjusted for probability of potential funding. See Note I "Commitments and Contingencies" for more information.
New Accounting Pronouncements | In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-04, Reference Rate Reform (Topic 848). The amendments in this ASU provide temporary, optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. The ASU primarily includes relief related to contract modifications and hedging relationships, as well as providing a one-time election for the sale or transfer of debt securities classified as held-to-maturity that reference a rate affected by the new guidance. This guidance is effective immediately and the amendments were originally to be applied prospectively through December 31, 2022. However, the FASB issued ASU 2022-06, deferring the sunset date to December 31, 2024. The Company has evaluated the regulatory requirements to cease the use of LIBOR and has put in place systems and capabilities for this purpose. The transition to the Secured Overnight Financing Rate ("SOFR") has been implemented by the Company, but some LIBOR benchmarked transactions have not yet moved to SOFR due to reset dates after July 1, 2023. All activities associated with reference rate reform will be concluded by the end of the fiscal year and within the specified sunset date for the ASU. The adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements. In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815). The amendments in this ASU clarify the guidance on ASC 815 on fair value hedge accounting of interest rate risk for portfolios and financial assets. Among other things, the amended guidance establishes the "last-of-layer" method for making the fair value hedge accounting for these portfolios more accessible and renames that method the "portfolio layer" method. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. We do not expect the amendments to have a material effect on our consolidated financial statements. In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326). The amendments in this ASU eliminate the guidance on troubled debt restructurings while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors made to borrowers experiencing financial difficulties. The ASU also requires that entities disclose current-period gross charge-offs by year of origination for loans and leases. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. We do not expect the amendments to have a material effect on our consolidated financial statements. In December of 2022, the SEC adopted amendments to Rule 10b5-1 and implemented new disclosure requirements in Item 408(a) of Regulation S-K. The requirements include quarterly disclosures on Form 10-Q and annual disclosures on Form 10-K about the adoption, termination and material terms of a Rule 10b5-1 trading plan or other preplanned trading arrangement by an issuer's directors or officers. The new requirements became effective for the first full fiscal period that began on or after April 1, 2023. The Company has currently has no Rule 10b5-1 plans in place but is evaluating the impact of these amendments and will apply as applicable. In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323). The amendments in this ASU expand the population of tax credit investments for which an investor may elect to apply the proportional amortization method ("PAM") and require certain disclosures for tax credit investments. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, with early adoption permitted. The Company has utilized PAM for low income housing tax credit investments. We do not expect this ASU to have a material effect on our consolidated financial statements. In May of 2023, the SEC adopted amendments to modernize the disclosure requirement relating to repurchases of an issuer's equity securities, including requiring issuers to provide daily repurchase activity on a quarterly or semi-annual basis, depending on type of issuer. The amendments will require issuers to disclose daily repurchase activity quarterly or semiannually, indicate if certain directors or officers traded in the relevant securities within four business days before or after the public announcement of an issuer's repurchase plan or program, provide narrative disclosure about the issuer's repurchase programs and practices in its periodic reports, and provide quarterly disclosure in an issuer's periodic reports on Forms 10-K and 10-Q related to an issuer's adoption and termination of 10b5-1 trading arrangements. Issuers are required to comply with these amendments on their Forms 10-Q and 10-K beginning with the first filing that covers the first full fiscal quarter that begins on or after October 1, 2023. The Company is currently evaluating the impact of these amendments and will apply as applicable.
Fair Value Measurements | FASB ASC 820, Fair Value Measurement ("ASC 820") defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active exchange markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active and other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Company has established and documented the process for determining the fair values of its assets and liabilities, where applicable. Fair value is based on quoted market prices, when available, for identical or similar assets or liabilities. In the absence of quoted market prices, fair value is determined using valuation models or third-party appraisals. The following is a description of the valuation methodologies used to measure and report the fair value of financial assets and liabilities on a recurring or nonrecurring basis. Measured on a Recurring Basis Available-for-Sale Securities and Derivative Contracts Securities available for sale are recorded at fair value on a recurring basis. The fair value of debt securities are priced using model pricing based on the securities' relationship to other benchmark quoted prices as provided by an independent third party, and under GAAP are considered a Level 2 input method. Securities that are traded on active exchanges are measured using the closing price in an active market and are considered a Level 1 input method. The Company offers interest rate swaps to its variable rate borrowers who want to manage their interest rate risk. At the same time, the Company enters into the opposite trade with a counterparty to offset its interest rate risk. The Company has also entered into commercial loan hedges, mortgage pool hedges and borrowings hedges using interest rate swaps. The fair value of these interest rate swaps are estimated by a third-party pricing service using a discounted cash flow technique. These are considered a Level 2 input method.
