NATURE OF OPERATIONS

Accounting Policies [Abstract]
NATURE OF OPERATIONS	NATURE OF OPERATIONS Organization Luther Burbank Corporation (the ‘‘Company’’), a California corporation headquartered in Santa Rosa, is the bank holding company for its wholly-owned subsidiary, Luther Burbank Savings (the "Bank"), and the Bank's wholly-owned subsidiary, Burbank Investor Services. The Company also owns Burbank Financial Inc., a real estate investment company that provides limited loan administrative support to the Bank, and all the common interests in Luther Burbank Statutory Trusts I and II, entities created to issue trust preferred securities. The Bank conducts its business from its executive offices in Santa Rosa and Gardena, California, and an administrative office in Irvine, California. It has ten full service branches in California located in Sonoma, Marin, Santa Clara, and Los Angeles Counties and one full service branch in Washington located in King County. Additionally, there are several loan production offices located throughout California. On November 13, 2022, the Company entered into an Agreement and Plan of Reorganization (the “Merger Agreement”) with Washington Federal, Inc. (“WAFD”), pursuant to which the Company will merge with and into WAFD (the “Corporate Merger”), with WAFD surviving the Corporate Merger. Promptly following the Corporate Merger, the Company’s wholly-owned bank subsidiary, Luther Burbank Savings, will be merged with and into Washington Federal Bank, dba WaFd Bank, the wholly-owned bank subsidiary of WAFD (“WAFD Bank”), with WAFD Bank as the surviving institution. Closing of the transaction, which is expected to occur in 2023, is contingent upon the receipt of all necessary regulatory approvals, along with the satisfaction of other customary closing conditions. On May 4, 2023, the shareholders of the Company and WAFD approved the Corporate Merger at their respective special meetings. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all footnotes as would be necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in stockholders’ equity and cash flows in conformity with accounting principles generally accepted in the United States of America (“GAAP”). However, these interim unaudited consolidated financial statements reflect all adjustments (consisting solely of normal recurring adjustments and accruals) which, in the opinion of management, are necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in stockholders’ equity and cash flows for the interim periods presented. These unaudited consolidated financial statements have been prepared on a basis consistent with, and should be read in conjunction with, the audited consolidated financial statements as of and for the year ended December 31, 2022, and the notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (the “SEC”), under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”). The unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated. The results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results of operations that may be expected for any other interim period or for the year ending December 31, 2023. The Company’s accounting and reporting policies conform to GAAP and to general practices within the banking industry. Use of Estimates Management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions affect the amounts reported in the unaudited consolidated financial statements and the disclosures provided, and actual results could differ. Earnings Per Share ("EPS") Basic earnings per common share represents the amount of earnings for the period available to each share of common stock outstanding during the reporting period. Basic EPS is computed based upon net income divided by the weighted average number of common shares outstanding during the period. In determining the weighted average number of shares outstanding, vested restricted stock units are included. Diluted EPS represents the amount of earnings for the period available to each share of common stock outstanding including common stock that would have been outstanding assuming the issuance of common shares for all dilutive potential common shares outstanding during each reporting period. Diluted EPS is computed based upon net income divided by the weighted average number of common shares outstanding during each period, adjusted for the effect of dilutive potential common shares, such as restricted stock awards and units, calculated using the treasury stock method.

The Company held 90 residential MBS and CMOs of which 86 were in a loss position and 14 had been in a loss position for twelve months or more. The Company held six agency bonds of which one was in a loss position for less than twelve months. The Company held three other ABS of which three were in a loss position and two had been in a loss position for twelve months or more. The unrealized losses on the Company’s investments were caused by interest rate changes. In addition, the contractual cash flows of these investments are guaranteed by the U.S. government or agencies sponsored by the U.S. government. Accordingly, it is expected that the securities will not be settled at a price less than amortized cost. Because the decline in market value is attributable to changes in interest rates but not credit quality, and because the Company has the ability and intent to hold those investments until a recovery of fair value, which may be maturity, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2023 or December 31, 2022. Additionally, the Company had no ACL recorded for available for sale investment securities at June 30, 2023. As of June 30, 2023 and December 31, 2022, there were no holdings of securities of any one issuer in an amount greater than 10% of stockholders' equity, other than the U.S. government and its agencies.

The unrecognized losses on the Company’s held to maturity investments at June 30, 2023 were caused by interest rate changes. In addition, the contractual cash flows of these investments are guaranteed by agencies sponsored by the U.S. government. Accordingly, it is expected that the securities will not be settled at a price less than amortized cost.

As such, mortgage backed securities, collateralized mortgage obligations and other asset backed securities are not included in the maturity categories above and instead are shown separately. As of June 30, 2023, securities with an amortized cost totaling $592.0 million were pledged to the FHLB and Federal Reserve Bank of San Francisco ("FRB") to secure borrowing arrangements. See Note 9 for additional information. No securities were pledged as of December 31, 2022. Equity Securities Equity securities consist of investments in a qualified community reinvestment fund. At both June 30, 2023 and December 31, 2022, the fair value of equity securities totaled $10.3 million. Changes in fair value are recognized in other noninterest income and totaled $(166) thousand and none during the three and six months ended June 30, 2023, respectively, compared to $(344) thousand and $(921) thousand during the

Prior to the Company’s adoption of CECL on January 1, 2023, the Company maintained an allowance for loan losses ("ALLL") in accordance with the probable incurred loss model. The probable incurred loss model was reflective of estimates for loan losses incurred and inherent in the loan portfolio as of the balance sheet date, and did not reflect current estimates of future expected credit losses over the lives of the Company’s loans, as now required by CECL.

During these internal reviews, management monitors and analyzes the financial condition of borrowers and guarantors, as well as the financial performance and/or other characteristics of loan collateral. These credit quality indicators are used to assign a risk rating to each individual loan. The risk ratings can be grouped into six major categories, defined as follows: Pass assets are those which are performing according to contract and have no existing or known weaknesses deserving of management’s close attention. The basic underwriting criteria used to approve the loans are still valid, and all payments have essentially been made as planned. Watch assets are expected to have an event occurring in the near future that will lead to a change in risk rating with the change being either favorable or unfavorable. These assets require heightened monitoring of the event by management. Special Mention assets have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Special mention assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification. Substandard assets are inadequately protected by the current net worth and/or paying capacity of the obligor or by the collateral pledged. These assets have well-defined weaknesses: the primary source of repayment is gone or severely impaired (i.e., bankruptcy or loss of employment) and/or there has been a deterioration in collateral value. In addition, there is the distinct possibility that the Company will sustain some loss, either directly or indirectly (i.e., the cost of monitoring), if the deficiencies are not corrected. A deterioration in collateral value alone does not mandate that an asset be adversely classified if such factor does not indicate that the primary source of repayment is in jeopardy. Doubtful assets have the weaknesses of those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable based on current facts, conditions and values. Loss assets are considered uncollectible and of such little value that their continuance as assets, without establishment of a specific valuation allowance or charge-off, is not warranted. This classification does not necessarily mean that an asset has absolutely no recovery or salvage value; but rather, it is not practical or desirable to defer writing off a basically worthless asset (or portion thereof) even though partial recovery may be affected in the future.

Loans that have been classified as collateral dependent are loans where substantially all repayment of the loan is expected to come from the operation of or eventual liquidation of the collateral. Collateral dependent loans are evaluated individually for purposes of measuring the ACL, which is determined based on the estimated fair value of the collateral. Estimates for costs to sell are included in the determination of the ACL when liquidation of the collateral is anticipated. In cases where the loan is well secured and the estimated value of the collateral exceeds the amortized cost of the loan, no ACL is recorded.

The Company does not have commitments to lend additional funds to borrowers with loans whose terms have been modified in TDRs. During the six months ended June 30, 2022, the Company modified the terms of one loan that qualified as a TDR. The following table provides details of this modification: (Dollars in thousands) Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Troubled debt restructurings: Single family residential 1 $ 405 $ 412 Terms of the modification above included suspension of loan payments for six months and a similar extension of the loan term. The TDR above resulted in no increase to the allowance for loan losses and no charge-offs primarily due to collateral support provided by the secondary source of repayment. The Company had no TDRs with a subsequent payment default within the twelve months following their modification during the three or six months ended June 30, 2022. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms.

The allowance for collateral dependent loans is determined based on the estimated fair value of the underlying collateral. Interest income on non-accrual loans is subsequently recognized on a cash basis as long as the remaining unpaid principal amount of the loans are deemed to be fully collectible. If there is doubt regarding the collectability of the loan, then any interest payments received are applied to principal. Interest income was recognized on a cash basis on non-accrual loans during the three and six months ended June 30, 2023 totaling $18 thousand and $46 thousand, respectively, compared to $27 thousand and $54 thousand during the three and six months ended June 30, 2022, respectively. Contractual interest not recorded on nonperforming loans during the three and six months ended June 30, 2023 totaled $124 thousand and $241 thousand, respectively, compared to $17 thousand and $24 thousand during the three and six months ended June 30, 2022, respectively.

MORTGAGE SERVICING RIGHTS	MORTGAGE SERVICING RIGHTS Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts, disbursing payments to investors, and conducting foreclosure proceedings. Loan servicing income is recorded on the accrual basis and includes servicing fees from investors and certain charges collected from borrowers. Mortgage loans serviced for others are not reported as assets. The principal balances of these loans are as follows: (Dollars in thousands) June 30, December 31, Mortgage loans serviced for: Federal Home Loan Mortgage Corporation ("Freddie Mac") $ 76,294 $ 80,478 Other financial institutions 36,044 37,503 Total mortgage loans serviced for others $ 112,338 $ 117,981 Custodial account balances maintained in connection with serviced loans totaled $2.5 million and $234 thousand at June 30, 2023 and December 31, 2022, respectively. The Company measures servicing rights at fair value at each reporting date and reports changes in the fair value of servicing assets in earnings in the period in which the changes occur. Fair value is based on a valuation model that calculates the present value of estimated future net servicing income. Activities for mortgage servicing rights are as follows: Three Months Ended June 30, Six Months Ended June 30, (Dollars in thousands) 2023 2022 2023 2022 Beginning balance $ 669 $ 811 $ 688 $ 915 Additions — — — — Disposals — — — — Changes in fair value due to changes in assumptions — — — — Other changes in fair value (30) (32) (49) (136) Ending balance $ 639 $ 779 $ 639 $ 779

LEASES

LEASES	6 Months Ended

Leases [Abstract]
LEASES	LEASES The Company leases various office premises under long-term operating lease agreements. These leases expire between 2024 and 2033, with certain leases containing five-year renewal options. The Company includes lease extension options in the lease term, if it is reasonably certain the Company will exercise the option, when considering the economic incentive to do so. Leases are classified as operating or finance leases at the lease commencement date. Lease expense for operating leases and short-term leases is recognized on a straight-line basis over the lease term. All of the Company’s leases are classified as operating leases. The Company records operating lease right-of-use assets and operating lease liabilities on the Company's consolidated statements of financial condition. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The Company uses its incremental borrowing rate at lease commencement to discount lease payments when the rate implicit in the lease is not readily determinable. The Company selected a FHLB advance rate at lease inception based on the lease term and other factors, as a reasonable incremental borrowing rate.

Debt Disclosure [Abstract]
JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURES	JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURES The Company formed two wholly-owned trust companies (the ‘‘Trusts’’) which issued guaranteed preferred beneficial interests (the "Trust Securities") in the Company’s junior subordinated deferrable interest debentures (the "Notes"). The Company is not considered the primary beneficiary of the Trusts and therefore, the Trusts are not consolidated in the Company’s financial statements, but rather the junior subordinated debentures are shown as a liability. The Company’s investment in the common securities of the Trusts, totaling $1.9 million, is included in other assets in the consolidated statements of financial condition. The sole asset of the Trusts are the Notes that they hold. The Trusts have invested the proceeds of such Trust Securities in the Notes. Each of the Notes has an interest rate equal to the corresponding Trust Securities distribution rate. The Company has the right to defer payment of interest on the Notes at any time or from time to time for a period not exceeding five years provided that no extension period may extend beyond the stated maturity of the relevant Notes. During any such extension period, distributions on the Trust Securities will also be deferred, and the Company’s ability to pay dividends on its common stock will be restricted. The Company has entered into contractual arrangements which, taken collectively, fully and unconditionally guarantee payment of: (i) accrued and unpaid distributions required to be paid on the Trust Securities; (ii) the redemption price with respect to any Trust Securities called for redemption by the Trusts; and (iii) payments due upon a voluntary or involuntary dissolution, winding up or liquidation of the Trusts. The Trust Securities are mandatorily redeemable upon maturity of the Notes, or upon earlier redemption as provided in the indenture. The Company has the right to redeem the Notes purchased by the Trusts, in whole or in part, on or after the redemption date. As specified in the indenture, if the Notes are redeemed prior to maturity, the redemption price will be the principal amount and any accrued but unpaid interest.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING ACTIVITIES	DERIVATIVES AND HEDGING ACTIVITIES From time to time, the Company utilizes interest rate swaps and other derivative financial instruments as part of its asset liability management strategy to manage interest rate risk positions. Fair Value Hedges of Interest Rate Risk As of June 30, 2023, the Company held 10 interest rate swaps with a total notional amount of $1.5 billion. The swaps provide a hedge against the interest rate risk associated with both fixed rate loans and hybrid adjustable loans in their fixed rate period. All outstanding swaps are designated as fair value hedges and involve the payment of a fixed rate amount to a counterparty in exchange for the Company receiving a variable rate payment over the life of the swaps without the exchange of the underlying notional amount. Any gain or loss on the derivatives, as well as any offsetting loss or gain on the hedged items attributable to the hedged risk are recognized in interest income on loans. The following table presents the effect of the Company’s interest rate swaps on the unaudited consolidated statements of income for the three and six months ended June 30, 2023 and 2022: For the Three Months Ended June 30, For the Six Months Ended June 30, (Dollars in thousands) 2023 2022 2023 2022 Derivative - interest rate swaps: Interest income $ 8,136 $ 498 $ 16,300 $ 433 Hedged items - loans: Interest income (loss) 91 (35) (29) (48) Net increase in interest income $ 8,227 $ 463 $ 16,271 $ 385 The following table presents the fair value of the Company’s interest rate swaps, as well as their classification in the consolidated statements of financial condition as of June 30, 2023 and December 31, 2022: Fair Values of Derivative Instruments Asset Derivatives Liability Derivatives (Dollars in thousands) Notional Amount Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives designated as hedging instruments: As of June 30, 2023: Interest Rate Swaps $ 1,500,000 Prepaid Expenses and Other Assets $ 19,827 Other Liabilities and Accrued Expenses $ — As of December 31, 2022: Interest Rate Swaps $ 1,850,000 Prepaid Expenses and Other Assets $ 21,323 Other Liabilities and Accrued Expenses $ 2,136 As of June 30, 2023 and December 31, 2022, the following amounts were recorded in the consolidated statements of financial condition related to cumulative basis adjustments for its fair value hedges: Line Item in the Consolidated Statements of Financial Condition in Which the Hedged Items are Included (1) Carrying Amount of the Hedged Assets Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets (Dollars in thousands) As of June 30, 2023: Loans receivable, net $ 1,479,971 $ (20,029) As of December 31, 2022: Loans receivable, net $ 1,430,641 $ (19,359)

Share-Based Payment Arrangement [Abstract]
STOCK BASED COMPENSATION	STOCK BASED COMPENSATION The Company’s stock based compensation consists of restricted stock awards ("RSAs") and restricted stock units ("RSUs") granted under the Luther Burbank Corporation Omnibus Equity and Incentive Compensation Plan ("Omnibus Plan"). In connection with its initial public offering ("IPO") in December 2017, the Company granted RSUs in exchange for unvested phantom stock awards related to a then discontinued employee benefit plan that awarded phantom stock to certain key executives and nonemployee directors. The RSUs were granted on a per share basis, with the same vesting schedule and deferral elections that existed for the original phantom stock awards. Post IPO, the Company typically grants RSAs to nonemployee directors and certain employees on an annual basis. RSA grants vest after one year for nonemployee directors and ratably over three All RSAs and RSUs are granted at the fair value of the common stock at the time of the award. RSAs and RSUs are considered fixed awards as the number of shares and fair value are known at the date of grant and the fair value at the grant date is amortized over the vesting and/or service period. Non-cash stock compensation expense recognized for RSAs for the three and six months ended June 30, 2023 totaled $471 thousand and $944 thousand, respectively, compared to $616 thousand and $1.3 million for the three and six months ended June 30, 2022. The fair value of RSAs that vested during the six months ended June 30, 2023 and 2022 totaled $2.7 million and $2.6 million, respectively. No RSAs or RSUs vested during the three months ended June 30, 3023 or 2022. As of June 30, 2023 and December 31, 2022, there was $1.9 million and $2.4 million, respectively, of unrecognized compensation expense related to 229,460 and 414,004 unvested RSAs, respectively, which amounts were expected to be expensed over a weighted average period of 1.30 years and 1.74 years, respectively. As of June 30, 2023 and December 31, 2022, 65,799 and 81,225 shares, respectively, of RSUs were vested and remain unsettled per the original deferral elections. There were no unvested RSUs at June 30, 2023 or December 31, 2022.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended
	Jun. 30, 2023
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Fair Value Hierarchy The Company groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Valuations within these levels are based upon: Level 1 - Quoted market prices for identical instruments traded in active exchange markets. Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable or can be corroborated by observable market data. Level 3 - Model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use on pricing the asset or liability. Valuation techniques include management judgment and estimation which may be significant. Because broadly traded markets do not exist for most of the Company’s financial instruments, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein do not represent, and should not be construed to represent, the underlying value of the Company. Management monitors the availability of observable market data to assess the appropriate classification of assets and liabilities within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. Management evaluates the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total assets, total liabilities, or total earnings. The following methods and assumptions were used to estimate the fair value of financial instruments: For cash and cash equivalents, accrued interest receivable and payable, demand deposits and short-term borrowings, the carrying amount was estimated to be fair value. The fair value of accrued interest receivable/payable balances were determined using inputs and fair value measurements commensurate with the asset or liability from which the accrued interest is generated. Fair values for available for sale and held to maturity debt securities, which include primarily debt securities issued by U.S. government sponsored agencies, were based on quoted market prices for similar securities. Fair values for equity securities, which consist of investments in a qualified community reinvestment fund, were based on quoted market prices. Loans were valued using the exit price notion. The fair value was estimated using market quotes for similar assets or the present value of future cash flows, discounted using a market rate for similar products and giving consideration to estimated prepayment risk and credit risk. The fair value of loans was determined utilizing estimates resulting in a Level 3 classification. The fair value of collateral dependent loans were measured based on the fair value of the collateral at the reporting date, adjusted for selling costs. The fair value of collateral dependent loans was determined utilizing estimates resulting in a Level 3 classification. It was not practicable to determine the fair value of FHLB stock due to restrictions placed on its transferability. The fair value of servicing rights was determined using a valuation model that utilizes interest rate, prepayment speed, and default rate assumptions that market participants would use in estimating future net servicing income and that can be validated against available market data. The fair values of derivatives were based on valuation models using observable market data as of the measurement date. Fair values for fixed-rate time deposits were estimated using discounted cash flow analyses using interest rates offered at each reporting date by the Company for time deposits with similar remaining maturities. For deposits with no contractual maturity, the fair value was assumed to equal the carrying value. The fair value of FHLB advances was estimated based on discounting the future cash flows using the market rate currently offered for similar terms. The fair value of subordinated debentures was based on an indication of value provided by a third-party broker. For senior debt, the fair value was based on an indication of value provided by a third-party broker.

VARIABLE INTEREST ENTITIES (VIE

VARIABLE INTEREST ENTITIES (VIE)	6 Months Ended
	Jun. 30, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
VARIABLE INTEREST ENTITIES (VIE)	VARIABLE INTEREST ENTITIES ("VIE")The Company is involved with VIEs through its loan securitization activities. The Company evaluated its association with VIEs for consolidation purposes. Specifically, a VIE is to be consolidated by its primary beneficiary, the entity that has both the power to direct the activities that most significantly impact the VIE, and a variable interest that could potentially be significant to the VIE. A variable interest is a contractual, ownership or other interest whose value fluctuates with the changes in the value of the VIE's assets and liabilities. The assessment includes an evaluation of the Company's continuing involvement with the VIE and the nature and significance of its variable interests. Multifamily loan securitization With respect to the securitization transaction with Freddie Mac which settled September 27, 2017, the Company's variable interests reside with a reimbursement agreement entered into with Freddie Mac that obligates the Company to reimburse Freddie Mac for defaulted contractual principal and interest payments identified after the ultimate resolution of any defaulted loans. Such reimbursement obligations are not to exceed 10% of the original principal amount of the loans comprising the securitization pool. As part of the securitization transaction, the Company released all servicing obligations and rights to Freddie Mac who was designated as the Master Servicer. As Master Servicer, Freddie Mac appointed the Company with sub-servicing obligations, which include obligations to collect and remit payments of principal and interest, manage payments of taxes and insurance, and otherwise administer the underlying loans. The servicing of defaulted loans and foreclosed loans was assigned to a separate third party entity, independent of the Company and Freddie Mac. Freddie Mac, in its capacity as Master Servicer, can terminate the Company in its role as sub-servicer and direct such responsibilities accordingly. In evaluating the variable interests and continuing involvement in the VIE, the Company determined that it does not have the power to make significant decisions or direct the activities that most significantly impact the economic performance of the VIE's assets and liabilities. As sub-servicer of the loans, the Company does not have the authority to make significant decisions that influence the value of the VIE's net assets and therefore, is not the primary beneficiary of the VIE. Hence, the Company determined that the VIE associated with the multifamily securitization should not be included in the consolidated financial statements of the Company.

Transfers and Servicing [Abstract]
LOAN SALE AND SECURITIZATION ACTIVITIES	LOAN SALE AND SECURITIZATION ACTIVITIES The Company periodically sells loans as part of its business operations and overall management of liquidity, assets and liabilities, and financial performance. The transfer of loans is executed in securitization or sale transactions. With respect to sale transactions, the Company's continuing involvement may or may not include ongoing servicing responsibilities and general representations and warranties. With respect to securitization sales, the Company executed its first and only transaction to date on September 27, 2017 with Freddie Mac. The transaction involved the sale of $626.0 million in originated multifamily loans through a Freddie Mac sponsored transaction. The Company's continuing involvement includes sub-servicing responsibilities, general representations and warranties, and a limited reimbursement obligation. As sub-servicer for Freddie Mac, the Bank is required to maintain a minimum net worth in accordance with GAAP of not less than $2.0 million. If the Bank's capital were to fall below this threshold, Freddie Mac would have the authority to terminate and assume the Bank’s sub-servicing duties. At June 30, 2023, the Bank’s net worth was $839.9 million which equates to its Tier 1 capital of $874.0 million plus goodwill of $3.3 million less accumulated other comprehensive loss related to net unrealized losses on available for sale securities of $37.5 million. General representations and warranties associated with loan sales and the securitization transaction require the Company to uphold various assertions that pertain to the underlying loans at the time of the transaction, including, but not limited to, compliance with relevant laws and regulations, absence of fraud, enforcement of liens, no environmental damages, and maintenance of relevant environmental insurance. Such representations and warranties are limited to those that do not meet the quality represented at the transaction date and do not pertain to a decline in value or future payment defaults. In circumstances where the Company breaches its representations and warranties, the Company would generally be required to cure such instances through a repurchase or substitution of the subject loan(s). With respect to the securitization transaction, the Company also has continuing involvement through a reimbursement agreement executed with Freddie Mac. To the extent the ultimate resolution of defaulted loans results in contractual principal and interest payments that are deficient, the Company is obligated to reimburse Freddie Mac for such amounts, not to exceed 10% of the original principal amount of the loans comprising the securitization pool at the closing date of September 27, 2017.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Financial Instruments with Off-Balance Sheet Risk The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments represent commitments to originate fixed and variable rate loans and loans in process, and involve, to varying degrees, credit risk and interest rate risk in excess of the amount recognized in the Company’s consolidated statements of financial condition. The Company’s exposure to credit loss in the event of nonperformance by the other party for commitments to extend credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments to originate loans and lines of credit as it does for on-balance sheet instruments. As it relates to interest rate risk, the Company's exposure is generally limited to increases in interest rates that may result during the short period of time between the commitment and funding of fixed rate credit facilities and adjustable rate credit facilities with initial fixed rate periods. The limited timing risk associated with these credit facilities are considered within the Company's asset liability management process. Commitments to fund loans and lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have expiration dates or other termination clauses. In addition, external market forces may impact the probability of commitments being exercised; therefore, total commitments outstanding do not necessarily represent future cash requirements. At June 30, 2023 and December 31, 2022, the Company had outstanding commitments of approximately $27.0 million and $37.7 million, respectively, for loans. Unfunded commitment reserves totaled $303 thousand and $125 thousand at June 30, 2023 and December 31, 2022, respectively. The Company adopted the CECL accounting standard on January 1, 2023. Upon adoption, the Company increased the allowance for unfunded loan commitments by $330 thousand, which represented the difference between the allowance calculated under the CECL methodology as of January 1, 2023 and the incurred loss methodology as of December 31, 2022. The $330 thousand increase in the allowance for unfunded loan commitments was primarily due to higher lifetime expected losses on unfunded commitments on construction loans under the CECL methodology. Contingencies At present, there are no pending or threatened proceedings against the Company which, if determined adversely, would have a material effect on the Company’s business, financial position, results of operations or cash flows. In the ordinary course of operations, as well as in connection with the pending merger with WAFD, the Company may be party to various legal proceedings. Correspondent Banking Agreements

Accounting Policies [Abstract]
Basis of Accounting	The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all footnotes as would be necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in stockholders’ equity and cash flows in conformity with accounting principles generally accepted in the United States of America (“GAAP”). However, these interim unaudited consolidated financial statements reflect all adjustments (consisting solely of normal recurring adjustments and accruals) which, in the opinion of management, are necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in stockholders’ equity and cash flows for the interim periods presented. These unaudited consolidated financial statements have been prepared on a basis consistent with, and should be read in conjunction with, the audited consolidated financial statements as of and for the year ended December 31, 2022, and the notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (the “SEC”), under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”). The unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated.
Use of Estimates	Management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions affect the amounts reported in the unaudited consolidated financial statements and the disclosures provided, and actual results could differ.
Earnings Per Share	Basic earnings per common share represents the amount of earnings for the period available to each share of common stock outstanding during the reporting period. Basic EPS is computed based upon net income divided by the weighted average number of common shares outstanding during the period. In determining the weighted average number of shares outstanding, vested restricted stock units are included. Diluted EPS represents the amount of earnings for the period available to each share of common stock outstanding including common stock that would have been outstanding assuming the issuance of common shares for all dilutive potential common shares outstanding during each reporting period. Diluted EPS is computed based upon net income divided by the weighted average number of common shares outstanding during each period, adjusted for the effect of dilutive potential common shares, such as restricted stock awards and units, calculated using the treasury stock method.
New Financial Accounting Standards	The Company adopted CECL using the modified retrospective method for all financial assets measured at cost, including loans, HTM debt securities and off-balance sheet credit exposures. Results for reporting periods beginning January 1, 2023 are reported under ASU 2016-13, while prior period results continue to be reported under the incurred loss model which was the previously applicable GAAP. The Company recorded an increase to its ACL of $119 thousand as a cumulative effect adjustment of adopting ASU 2016-13, with a corresponding decrease in retained earnings, net of $35 thousand in taxes, of $84 thousand. The transition adjustment reflects the results of our model in estimating lifetime expected credit losses on loans, unfunded commitments and other off-balance sheet credit exposures.
Derivatives	Any gain or loss on the derivatives, as well as any offsetting loss or gain on the hedged items attributable to the hedged risk are recognized in interest income on loans.
Fair Value Measurements	The Company groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Valuations within these levels are based upon: Level 1 - Quoted market prices for identical instruments traded in active exchange markets. Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable or can be corroborated by observable market data. Level 3 - Model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use on pricing the asset or liability. Valuation techniques include management judgment and estimation which may be significant. Because broadly traded markets do not exist for most of the Company’s financial instruments, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein do not represent, and should not be construed to represent, the underlying value of the Company. Management monitors the availability of observable market data to assess the appropriate classification of assets and liabilities within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. Management evaluates the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total assets, total liabilities, or total earnings. The following methods and assumptions were used to estimate the fair value of financial instruments: For cash and cash equivalents, accrued interest receivable and payable, demand deposits and short-term borrowings, the carrying amount was estimated to be fair value. The fair value of accrued interest receivable/payable balances were determined using inputs and fair value measurements commensurate with the asset or liability from which the accrued interest is generated. Fair values for available for sale and held to maturity debt securities, which include primarily debt securities issued by U.S. government sponsored agencies, were based on quoted market prices for similar securities. Fair values for equity securities, which consist of investments in a qualified community reinvestment fund, were based on quoted market prices. Loans were valued using the exit price notion. The fair value was estimated using market quotes for similar assets or the present value of future cash flows, discounted using a market rate for similar products and giving consideration to estimated prepayment risk and credit risk. The fair value of loans was determined utilizing estimates resulting in a Level 3 classification. The fair value of collateral dependent loans were measured based on the fair value of the collateral at the reporting date, adjusted for selling costs. The fair value of collateral dependent loans was determined utilizing estimates resulting in a Level 3 classification. It was not practicable to determine the fair value of FHLB stock due to restrictions placed on its transferability. The fair value of servicing rights was determined using a valuation model that utilizes interest rate, prepayment speed, and default rate assumptions that market participants would use in estimating future net servicing income and that can be validated against available market data. The fair values of derivatives were based on valuation models using observable market data as of the measurement date. Fair values for fixed-rate time deposits were estimated using discounted cash flow analyses using interest rates offered at each reporting date by the Company for time deposits with similar remaining maturities. For deposits with no contractual maturity, the fair value was assumed to equal the carrying value. The fair value of FHLB advances was estimated based on discounting the future cash flows using the market rate currently offered for similar terms. The fair value of subordinated debentures was based on an indication of value provided by a third-party broker. For senior debt, the fair value was based on an indication of value provided by a third-party broker.
Leases	The Company includes lease extension options in the lease term, if it is reasonably certain the Company will exercise the option, when considering the economic incentive to do so. Leases are classified as operating or finance leases at the lease commencement date. Lease expense for operating leases and short-term leases is recognized on a straight-line basis over the lease term. All of the Company’s leases are classified as operating leases. The Company records operating lease right-of-use assets and operating lease liabilities on the Company's consolidated statements of financial condition. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The Company uses its incremental borrowing rate at lease commencement to discount lease payments
