SUMMARY OF SIGNIFICANT ACCOUNTI

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: HomeStreet, Inc. and its wholly owned subsidiaries (the "Company") is a diversified financial services company serving customers primarily in the Western United States. The Company is principally engaged in commercial banking, mortgage banking and consumer/retail banking activities. The Company's consolidated financial statements include the accounts of HomeStreet, Inc. and its wholly owned subsidiaries, HomeStreet Capital Corporation, HomeStreet Statutory Trusts and HomeStreet Bank (the "Bank") and the Bank's subsidiaries, HomeStreet Reinsurance, Ltd., Continental Escrow Company, HomeStreet Foundation, HS Properties, Inc., HS Evergreen Corporate Center LLC, Union Street Holdings LLC and HS Cascadia Holdings LLC. HomeStreet Bank was formed in 1986 and is a state-chartered commercial bank. The Company's accounting and financial reporting policies conform with accounting principles generally accepted in the United States of America ("GAAP"). Inter-company balances and transactions have been eliminated in consolidation. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and revenues and expenses during the reporting periods and related disclosures. We have reclassified certain amounts in our consolidated financial statements for prior periods to conform with our current presentation. Immaterial Restatement: Subsequent to issuance of the June 30, 2020 financial statements, management concluded that purchases of and proceeds from the sale of Federal Home Loan Bank stock were incorrectly classified as financing activities, rather than investing activities, in the consolidated statements of cash flows. To correct this classification error, amounts previously reported for the purchases of and proceeds from the sale of Federal Home Loan Bank stock for the nine months ended September 30, 2019 as financing activities are reported as investing activities in the consolidated statement of cash flows. These unaudited interim financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results of the periods presented. These adjustments are of a normal recurring nature, unless otherwise disclosed in this Quarterly Report on Form 10-Q. The results of operations in the interim financial statements do not necessarily indicate the results that may be expected for the full year. The interim financial information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2019, filed with the Securities and Exchange Commission ("2019 Annual Report on Form 10-K"). Risks and Uncertainties The worldwide spread of coronavirus (“COVID-19”) has created significant uncertainty in the global, national, regional and local economies. There have been no comparable recent events that provide guidance to the effects of the spread of COVID-19 as a global pandemic may have, and, as a result, the near-term, short-term and ultimate impacts of COVID-19 and the extent to which COVID-19 impacts the Company’s business, results of operations and financial condition will depend on future developments, which are highly uncertain and difficult to predict. Share Repurchase Program At the beginning of 2020, the Company had in place a share repurchase program under which the Company could purchase up to $8.1 million of its common stock. During the first quarter of 2020 and again in the third quarter of 2020, the Board authorized two additional programs, each for the repurchase of an additional $25 million of the Company’s common stock. During the first nine months of 2020, the Company repurchased 1,995,845 shares of its common stock at an average price of $26.03 per share. Recent Accounting Developments In December 2019, the Financial Accounting Standards Board ("FASB") issued ASU No 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 removes certain exceptions to the general principles in Topic 740 in Generally Accepted Accounting Principles. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company does not expect ASU 2019-12 to have a material effect on the Company’s current financial position, results of operations or financial statement disclosures. On January 1, 2020, the Company adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which replaces the incurred loss methodology ("ALLL") with an expected loss methodology that is referred to as the current expected credit losses ("CECL") methodology. The measurement of the expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures such as loan commitments. In addition, ASC 326 made changes to the accounting for credit losses for AFS debt securities. The Company adopted CECL using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet ("OBS") credit exposure. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a decrease of $3.7 million to the beginning balance of retained earnings on January 1, 2020 for the cumulative effect of adopting this guidance. The Company adopted ASU 2016-13 using the prospective transition approach for debt securities for which other-than-temporary impairment had been recognized prior to January 1, 2020. As a result, the amortized cost basis remains the same before and after the effective date of this guidance. The following table illustrates the impact of the adoption of CECL on January 1, 2020. (in thousands) As reported under ASC 450-20 Impact of ASC 326 adoption As reported under ASC 326 Assets (1) LHFI Consumer loans Single family $ 6,450 $ 468 $ 6,918 Home equity and other 6,233 4,635 10,868 Total 12,683 5,103 17,786 Commercial real estate loans Non-owner occupied commercial real estate 7,245 (3,392) 3,853 Multifamily 7,015 (2,977) 4,038 Construction/land development Multifamily construction 2,848 693 3,541 Commercial real estate construction 624 (115) 509 Single family construction 3,800 4,280 8,080 Single family construction to permanent 1,003 200 1,203 Total 22,535 (1,311) 21,224 Commercial and industrial loans Owner occupied commercial real estate 3,639 (2,459) 1,180 Commercial business 2,915 510 3,425 Total 6,554 (1,949) 4,605 Total allowance for credit losses 41,772 1,843 43,615 Liabilities Allowance for credit losses on unfunded loan commitments 1,065 1,897 2,962 Total $ 42,837 $ 3,740 $ 46,577 (1) There was no impact from the adoption of this standard for either held to maturity ("HTM") or AFS investment securities. The following accounting policies have been updated to reflect the adoption of CECL. Allowance for Credit Losses for LHFI The allowance for credit losses ("ACL") for LHFI is a valuation account that is deducted from the loans amortized cost basis to present the net amount expected to be collected on the loans. Loan balances are charged off against the allowance when management believes the non-collectability of a loan balance is confirmed. Expected recoveries may not exceed the aggregate of amounts previously charged-off and expected to be charged-off. The ACL for LHFI, as reported in our consolidated balance sheets, is adjusted by a provision for credit losses and reduced by the charge-offs of loan amounts, net of recoveries. Management estimates the ACL balance using relevant available information from internal and external sources relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix or delinquency levels or other relevant factors. The credit loss estimation process involves procedures to appropriately consider the unique characteristics of its two loan portfolio segments, the consumer loan portfolio segment and the commercial loan portfolio segment. These two segments are further disaggregated into loan pools, the level at which credit risk is monitored. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Determining the appropriateness of the ACL is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall loan portfolio, based on the factors and forecasts then prevailing, may result in material changes in the ACL and provision for credit losses in those future periods. Credit Loss Measurement The allowance level is influenced by current conditions related to loan volumes, loan asset quality ratings ("AQR") migration or delinquency status, historic loss experience and other conditions influencing loss expectations, such as reasonable and supportable forecasts of economic conditions. The methodology for estimating the amount of expected credit losses has two basic components: first, a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics and second an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. Loans that Share Similar Risk Characteristics with Other Loans In estimating the component of the ACL, for loans that share similar risk characteristics with other loans, loans are segregated into loan pools based on similar risk characteristics, like product types or areas of risk concentration. The Company's ACL model methodology is to build a reserve rate using historical life of loan default rates combined with assessments of current loan portfolio information and forecasted economic environment and business cycle information. The model uses statistical analysis to determine the life of loan default rates for the quantitative component and analyzes qualitative factors (Q-Factors) that assess the current loan portfolio conditions and forecasted economic environment. Below is the general overview our ACL model. Historical Loss Rate The Company chose to analyze loan data from a full economic cycle, to the extent that data was available, to calculate life of loan loss rates. Based on the current economic environment and available loan level data, it was determined the Loss Horizon Period (LHP) should begin prior to the economic recession that began in 2007. The Company plans to monitor and review the LHP on an annual basis to determine appropriate time frames to be included based on economic indicators. Under CECL, the Company groups pools of loans by similar risk characteristics. Using these pools, sub-pools are established at a more granular level incorporating delinquency status and original FICO or original LTV (for consumer loans) and risk ratings (for commercial loans). Using the pool and sub-pool structure, cohorts are established historically on a quarterly basis containing the population in these sets as of that point in time. After the establishment of these cohorts, the loans within the cohorts are then tracked from that point forward to establish long-term Probability of Default ("PD") at the sub-pool level and Loss Given Default ("LGD") for the pool level. These historical cohorts and their PD/LGD outcomes are then averaged together to establish expected PDs and LGDs for each sub-pool. Once historical cohorts are established, the loans in the cohort are tracked moving forward for default events. The Company has defined default events as the first dollar of loss. If a loan in the cohort has experienced a default event over the LHP then the balance of the loan at the time of cohort establishment becomes part of the numerator of the PD calculation. The Loss Given Probability of Default ("LGPD") or Expected Loss ("EL") is the weighted average PD for each sub-pool cohort times the average LGD for each pool. The output from the model then is a series of EL rates for each loan sub-pool, which are applied to the related outstanding balances for each loan sub-pool to determine the ACL reserve based on historical loss rates. Q-Factors The Q-Factors adjust the expected historic loss rates for current and forecasted conditions that are not provided for in the historical loss information. The Company has established a methodology for adjusting historical expected loss rates based on these more recent or forecasted changes. The Q-Factor methodology is based on a blend of quantitative analysis and management judgment and reviewed on a quarterly basis. Each of the thirteen factors in the FASB standard were analyzed for common risk characteristics and grouped into seven consolidated Q-Factors as listed below. Qualitative Factor Financial Instruments - Credit Losses Portfolio Credit Quality The borrower's financial condition, credit rating, credit score, asset quality or business prospects The borrower's ability to make scheduled interest or principal payments The volume and severity of past due financial assets and the volume and severity of adversely classified or rated financial assets Remaining Payments The remaining payment terms of the financial assets The remaining time to maturity and the timing and extent of prepayments on the financial assets Volume & Nature The nature and volume of the entity's financial assets Collateral Values The value of underlying collateral on financial assets in which the collateral-dependent practical expedient has not been utilized Economic The environmental factors of a borrower and the areas in which the entity's credit is concentrated, such as: Changes and expected changes in national, regional and local economic and business conditions and developments in which the entity operates, including the condition and expected condition of various market segments Credit Culture The entity's lending policies and procedures, including changes in lending strategies, underwriting standards, collection, write-off and recovery practices, as well as knowledge of the borrower's operations or the borrower's standing in the community The quality of the entity's credit review system The experience, ability and depth of the entity's management, lending staff, and other relevant staff Business Environment The environmental factors of a borrower and the areas in which the entity's credit is concentrated, such as: Regulatory, legal, or technological environment to which the entity has exposure The environmental factors of a borrower and the areas in which the entity's credit is concentrated, such as: Changes and expected changes in the general market condition of either the geographical area or the industry to which the entity has exposure An eighth Q-Factor, Management Overlay, has been created to allow the Bank to adjust specific pools when conditions exist that were not contemplated in the model design that warrant an adjustment. The economic downturn caused by the COVID-19 pandemic and resulting accounting treatment of forbearances is an example of such a condition. The Company has chosen two years as the forecast period based on management judgment and has determined that reasonable and supportable forecasts should be made for two of the Q-Factors: Economic and Collateral values. Management has assigned weightings for each qualitative factor as well as individual metrics within each qualitative factor as to the relative importance of that factor or metric specific to each portfolio type. The Q-Factors above are evaluated using a seven-point scale ranging from significant improvement to significant deterioration. The CECL Q-Factor methodology bounds the Q-Factor adjustments by a minimum and maximum range, based on the Bank’s own historical expected loss rates for each respective pool. The rating of the Q-Factor on the seven-point scale, along with the allocated weight, determines the final expected loss adjustment. The model is constructed so that the total of the Q-Factor adjustments plus the current expected loss rate cannot exceed the maximum or minimum two-year loss rate for that pool, which is aligned with the Bank's chosen forecast period. Loss rates beyond two years are not adjusted in the Q-Factor process and the model reverts to the historical mean loss rates. Management Overlays are not bounded by the historical maximums. Quarterly, loan data is gathered to update the portfolio metrics analyzed in the Q-Factor model. The model is updated with current data and applicable forecasts, then the results are reviewed by management. After consensus is reached on all Q-Factor ratings, the results are input into the Q-Factor model and applied to the pooled loans which are reviewed to determine the adequacy of the reserve. Additional details describing the model by portfolio segment are below: Consumer Loan Portfolio The consumer loan portfolio segment is comprised of the single family and home equity loan classes, which are underwritten after evaluating a borrower's capacity, credit and collateral. Other consumer loans are grouped with home equity loans. Capacity refers to a borrower's ability to make payments on the loan. Several factors are considered when assessing a borrower's capacity, including the borrower's employment, income, current debt, assets and level of equity in the property. Credit refers to how well a borrower manages current and prior debts as documented by a credit report that provides credit scores and current and past information about the borrower's credit history. Collateral refers to the type and use of property, occupancy and market value. Property appraisals are obtained to assist in evaluating collateral. Loan-to-property value and debt-to-income ratios, loan amount and lien position are considered in assessing whether to originate a loan. These borrowers are particularly susceptible to downturns in economic trends such as conditions that negatively affect housing prices, demand for housing and levels of unemployment. Consumer Loan Portfolio Segment Estimated Loss Rate Model Under CECL, the Bank utilizes pools of loans that are grouped by similar risk characteristics: Single Family and Home Equity Loans which includes Consumer loans. Sub-Pools are established at a more granular level for the calculation of PDs, incorporating delinquency status, original FICO and original LTV. Consumer portfolio cohorts are established by grouping each ACL sub-pool at a point in time. Once historical cohorts are established, the loans in the cohort are tracked moving forward for default events. The Q-Factors adjust the expected historic loss rates for current and forecasted conditions that are not provided for in the historical loss information. For Single Family loans all Q-Factors noted above are evaluated. For the Home Equity and Consumer loans, collateral values are not evaluated as the Bank has determined the FICO score trends are a more relevant predictor of default than current collateral value for those types of loans. These factors are evaluated based on current conditions and forecasts (as applicable), using a seven-point scale ranging from significant improvement to significant deterioration. Commercial Loan Portfolio The commercial loan portfolio segment is comprised of the non-owner occupied commercial real estate, multifamily, construction and land development, owner occupied commercial real estate and commercial business loan classes, whose underwriting standards consider the factors described for single family and home equity loan classes as well as others when assessing the borrower's and associated guarantors or other related party’s financial position. These other factors include assessing liquidity, net worth, leverage, other outstanding indebtedness of the borrower, the quality and reliability of cash expected to flow through the borrower (including the outflow to other lenders) and prior known experiences with the borrower. This information is used to assess financial capacity, profitability and experience. Ultimate repayment of these loans is sensitive to interest rate changes, general economic conditions, liquidity and availability of long-term financing. Commercial Loan Portfolio Segment Loss Rate Model The Bank maintained loan classes above but has subdivided the construction and land development, which includes lot, land and acquisition and development loans, into the following ACL reporting pools to more accurately group risk characteristics: Multifamily, Commercial Real Estate, Single Family and Single Family construction to permanent. ACL sub-pools are established at a more granular level for the calculation of PDs, utilizing risk rating. As outlined in the Bank’s policies, commercial loans pools are non-homogenous and are regularly assessed for credit quality. For purposes of CECL, loans are sub-pooled according to the following AQR Ratings: • 1-6: These loans meet the definition of “Pass" assets. They are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less costs to acquire and sell in a timely manner, of any underlying collateral. The Bank further uses the available AQR ratings for components of the sub-pools. • 7: These loans meet the regulatory definition of “Special Mention.” They contain potential weaknesses, that if uncorrected may result in deterioration of the likelihood of repayment or in the Bank’s credit position. • 8: These loans meet the regulatory definition of “Substandard”. They are inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged, if any. They have well-defined weaknesses and have unsatisfactory characteristics causing unacceptable levels of risk. Commercial segment cohorts are established by grouping each ACL sub-pool at a point in time. Once historical cohorts are established, the loans in the cohort are tracked moving forward for default events. The Q-Factors adjust the expected historic loss rates for current and forecasted conditions that are not provided for in the historical loss information. All the Q-Factors noted above are evaluated for Commercial portfolio loans except for Commercial Business and Owner Occupied Commercial Real Estate ("CRE") loans which exclude the collateral values Q-Factor. The Company has determined that these loans are primarily underwritten by evaluating the cash flow of the business and not the underlying collateral. Factors above are evaluated based on current conditions and forecasts (as applicable), using a seven-point scale ranging from significant improvement to significant deterioration. Loans That Do Not Share Risk Characteristics with Other Loans For a loan that does not share risk characteristics with other loans, expected credit loss is measured on net realizable value that is the difference between the discounted value of the expected future cash flows, based on the original effective interest rate and the amortized cost basis of the loan. For these loans, we recognize expected credit loss equal to the amount by which the net realizable value of the loan is less than the amortized cost basis of the loan (which is net of previous charge-offs and deferred loan fees and costs), except when the loan is collateral dependent, which is when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In these cases, expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral. The fair value of the collateral is adjusted for the estimated costs to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. The starting point for determining the fair value of collateral is through obtaining external appraisals. Generally, collateral values for collateral dependent loans are updated every twelve months, either from external third parties or in-house certified appraisers. A third-party appraisal is required at least annually for substandard loans and OREO. Third party appraisals are obtained from a pre-approved list of independent, third party, local appraisal firms. Approval and addition to the list is based on experience, reputation, character, consistency and knowledge of the respective real estate market. Generally, appraisals are internally reviewed by the appraisal services group to ensure the quality of the appraisal and the expertise and independence of the appraiser. For performing consumer segment loans secured by real estate that are classified as collateral dependent, the Bank determines the fair value estimates quarterly using automated valuation services. Once the expected loss amount is determined, an allowance is recorded equal to the calculated expected credit loss and included in the ACL. If the calculated expected loss is determined to be permanent or not recoverable, the expected credit loss will be charged off. Factors considered by management in determining if the expected credit loss is permanent or not recoverable include whether management judges the loan to be uncollectible, repayment is deemed to be protracted beyond reasonable time frames, or the loss becomes evident owing to the borrower's lack of assets or, for single family loans, the loan is 180 days or more past due unless both well-secured and in the process of collection. Allowance for Credit Losses for Off-Balance Sheet Credit Exposures The Bank estimates expected credit losses over the contractual period in which the Bank is exposed to risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Bank. Reserves are required for OBS credit exposures that are not unconditionally cancellable. The allowance for credit losses on unfunded loan commitments is based on an estimate of unfunded commitment utilization over the life of the loan, applying the EL to the estimated utilization balance as of the reporting period. As these estimated credit loss calculations are similar to the funded LHFI they share similar risks plus the additional risk from estimating commitment utilization. Allowance for Credit Losses for Other Financial Instruments The Company evaluates AFS securities in an unrealized loss position, using a qualitative approach, at the end of each quarter to determine whether the decline in value is temporary or permanent. An unrealized loss exists when the fair value of an individual security is less than its amortized cost basis. When qualitative factors indicate that a credit loss may exist, the Company compares the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. The Company recognizes an ACL measured as the difference between the present value of expected cash flows and the amortized cost basis of the security, limited by the amount that the security’s fair value is less than its amortized cost basis. The Company does not believe any of these securities that were in an unrealized loss position at September 30, 2020 represent a credit loss impairment.

DISCONTINUED OPERATIONS

Discontinued Operations and Disposal Groups [Abstract]
DISCONTINUED OPERATIONS	DISCONTINUED OPERATIONS: On March 29, 2019, the Company successfully closed and settled two sales of the rights to service $14.3 billion in total unpaid principal balance of single family mortgage loans serviced for Federal National Mortgage Association ("Fannie Mae"), Federal Home Loan Mortgage Corporation ("Freddie Mac") and Government National Mortgage Association ("Ginnie Mae"), representing 71% of HomeStreet's total single family mortgage loans serviced for others portfolio as of December 31, 2018. The sales resulted in a $333 thousand pre-tax income and $941 thousand pre-tax loss from discontinued operations for the three and nine months ended September 30, 2019, respectively. The Company finalized the servicing transfer for these loans in 2019 and subserviced these loans through the transfer dates. These loans are excluded from the Company's mortgage servicing rights portfolio at September 30, 2019. On March 31, 2019, based on mortgage market conditions and the operating environment, the Board adopted a Resolution of Exit or Disposal of Home Loan Center ("HLC") Based Mortgage Banking Operations to sell or abandon the assets and related personnel associated with those operations. The assets that were sold or abandoned largely represented the Company's former Mortgage Banking segment, the activities of which related to originating, servicing, underwriting, funding and selling single family residential mortgage loans. The Company determined that the above actions constituted commitment to a plan of exit or disposal of certain long-lived assets (through sale or abandonment) and termination of employees. Further, the Company determined that the shift from a large-scale HLC based originator and servicer to a branch-focused product offering represented a strategic shift. As a result, the HLC-related mortgage banking operations are reported separately from the continuing operations as discontinued operations. In addition, the former Mortgage Banking operating segment and reporting unit were eliminated. This has resulted in a recast of the financial statements in 2019. On April 4, 2019 the Company entered into a definitive agreement related to the sale of the HLC based mortgage origination business assets and transfer of personnel to Homebridge Financial Services, Inc. ("Homebridge"). On June 24, 2019 the Company completed the sale with Homebridge. This sale included assets related to 47 stand-alone HLCs, sublease or lease assignments of the related offices and the transfer of certain related mortgage personnel. These HLCs, along with certain other mortgage banking related assets and liabilities that were to be sold or abandoned within one year, are classified as discontinued operations in 2019 in the accompanying consolidated financial statements. HLCs that were not subleased or assigned were closed during the second quarter of 2019 and none remain. Certain components of the Company's former Mortgage Banking segment, including mortgage servicing rights ("MSRs") on certain mortgage loans that were not part of the sales and right-of-use assets and lease liabilities where we did not obtain full landlord release were classified as continuing operations based on the Company's intent. At the end of the second quarter 2019, the Company also entered into a non-binding letter of interest to sell its ownership interest in WMS LLC at which time related operations also met the criteria to be classified as discontinued operations for the periods presented. The sales transaction was closed in November 2019, resulting in an immaterial loss on disposal. These discontinued operations activities, including the exit or disposal of the former Mortgage Banking Segment, were concluded by December 31, 2019. Consequently, we ceased discontinued operations accounting effective January 1, 2020. The following table summarizes the calculation of the net gain (loss) on disposal of discontinued operations.

The Company has evaluated investment securities AFS that are in an unrealized loss position and has determined that the decline in value is temporary and is related to the change in market interest rates since purchase. The decline in value is not related to the occurrence of any issuer-specific or industry-specific credit event. In addition, as of September 30, 2020 and December 31, 2019, the Company had not made a decision to sell any of its debt securities held, nor did the Company consider it more likely than not that it would be required to sell such securities before recovery of their amortized cost basis.

Receivables [Abstract]
LOANS AND CREDIT QUALITY	LOANS AND CREDIT QUALITY: As a result of the adoption of CECL on January 1, 2020, there is a lack of comparability in both the reserves and provisions for credit losses for the periods presented. Results for reporting periods beginning after January 1, 2020 are presented using the CECL methodology, while comparative period information continues to be reported in accordance with the incurred loss methodology in effect for prior periods. The Company's LHFI is divided into two portfolio segments, consumer loans and commercial loans. Within each portfolio segment, the Company monitors and assesses credit risk based on the risk characteristics of each of the following loan classes: single family and home equity and other loans within the consumer loan portfolio segment and non-owner occupied commercial real estate, multifamily, construction and land development, owner occupied commercial real estate and commercial business loans within the commercial loan portfolio segment. LHFI consist of the following.

(2) Net deferred loans fees and costs of $24.5 million are now included within the carrying amounts of the loan balances as of December 31, 2019, in order to conform to the current period presentation. Loans totaling $1.5 billion and $2.0 billion at September 30, 2020 and December 31, 2019, respectively, were pledged to secure borrowings from the Federal Home Loan Bank ("FHLB") and loans totaling $594 million and $491 million at September 30, 2020 and December 31, 2019, respectively, were pledged to secure borrowings from the Federal Reserve Bank. Credit Risk Concentrations Concentrations of credit risk arise when a number of customers are engaged in similar business activities or activities in the same geographic region, or when they have similar economic features that would cause their ability to meet contractual obligations to be similarly affected by changes in economic conditions. LHFI are primarily secured by real estate located in the Pacific Northwest, California and Hawaii. At September 30, 2020, the Company had one concentration representing 10% or more of the total portfolio by state and property type for the loan class of multifamily in the state of California, which represented 16.9% of the total portfolio. At December 31, 2019, we had concentrations representing 10% or more of the total portfolio by state and property type for the loan classes of single family in Washington and multifamily in California, which represented 10.7% and 12.2% of the total portfolio, respectively. Credit Quality Management considers the level of allowance of credit losses to be appropriate to cover credit losses expected over the life of the loans for the LHFI portfolio as of September 30, 2020. The cumulative loss rate used as the basis for the estimate of credit losses is comprised of the Bank’s historical loss experience and eight qualitative factors for current and forecasted periods. During the nine months ended September 30, 2020 the historical expected loss rates decreased from January 1, 2020 implementation due to minimal losses and our stable portfolio credit composition. During the nine months ended September 30, 2020, the Qualitative Factors increased significantly due to the forecasted impacts of the COVID-19 pandemic. As of September 30, 2020, the Bank expects that the markets in which it operates will have deterioration in collateral values and economic outlook over the two-year forecast period, with negative risk factors peaking in the first year and modestly improving in the second year. In addition to the ACL for LHFI, the Company maintains a separate allowance for credit losses on unfunded loan commitments which is included in accounts payable and other liabilities on our consolidated balance sheets. The allowance for credit losses on unfunded commitments was $1.8 million and $1.1 million at September 30, 2020 and December 31, 2019, respectively. The Bank has elected to exclude accrued interest receivable from the evaluation of the ACL. Accrued interest on LHFI was $21.1 million at September 30, 2020 and was reported in other assets in the consolidated balance sheets. Activity in the ACL was as follows.

The Company's risk rating methodology assigns risk ratings ranging from 1 to 10, where a higher rating represents higher risk. The risk rating of 9 is not used. Per the Company's policies, most commercial loans pools are non-homogenous and are regularly assessed for credit quality. The rating categories can be generally described by the following groupings for non-homogeneous loans: • 1-6: These loans meet the definition of “Pass" assets. They are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less costs to acquire and sell in a timely manner, of any underlying collateral. • 7: These loans meet the regulatory definition of “Special Mention.” They contain potential weaknesses, that if uncorrected may result in deterioration of the likelihood of repayment or in the Bank’s credit position. • 8: These loans meet the regulatory definition of “Substandard”. They are inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged, if any. They have well-defined weaknesses and have unsatisfactory characteristics causing unacceptable levels of risk. • 10: A loan, or the portion of a loan determined to meet the regulatory definition of “Loss.” The amounts classified as loss have been charged-off. The risk rating categories can be generally described by the following groupings for homogeneous loans: • 1-6: These loans meet the definition of “Pass" assets. A homogenous “Pass” loan is typically risk rated based on payment performance. • 7: These loans meet the regulatory definition of “Special Mention.” A homogeneous special mention loan, risk rated 7, is less than 90 days past due from the required payment date at month-end. • 8: These loans meet the regulatory definition of “Substandard”. A homogeneous substandard loan, risk rated 8, is 90 days or more past due from the required payment date at month-end. • 10: These loans meet the regulatory definition of “Loss”. A closed-end homogeneous loan not secured by real estate is risk rated 10 when past due 120 cumulative days or more from the contractual due date. Closed-end homogenous loans secured by real estate and all open-end homogenous loans are risk rated 10 when past due 180 cumulative days or more from the contractual due date. These loans, or the portion of these loans classified as loss, are generally charged-off in the month in which the applicable past due period elapses. Small balance commercial loans are generally considered homogenous unless 30 days or more past due or modified in a troubled debt restructuring that was an interest rate concession or payment modification with a significant balloon and the concession period has not been completed. The risk rating classification for such loans are based on the non-homogenous definitions noted above. Residential, home equity and consumer loans modified in a troubled debt restructuring are considered homogeneous unless the modification was an interest rate concession or payment modification with a significant balloon and the concession modification period has not been completed. The risk rating classification for such loans are based on the non-homogeneous definitions noted above.

In these cases, expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral. The fair value of the collateral is adjusted for the estimated costs to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. The following table presents the amortized cost basis of collateral-dependent loans by loan sub-class and collateral type. All collateral dependent loans are reviewed quarterly and loan amounts are charged down to fair value of the collateral, less costs to sell if the loss is confirmed and the expected repayment is from the sale of the collateral. If the expected repayment of the loan is from the operation of the collateral, then the cost of sale is not deducted from the fair value of the collateral.

A TDR loan is considered re-defaulted when it becomes doubtful that the objectives of the modifications will be met, generally when a consumer loan TDR becomes 60 days or more past due on principal or interest payments or when a commercial loan TDR becomes 90 days or more past due on principal or interest payments.

In addition, interagency guidance issued by federal banking regulators and endorsed by the FASB staff has indicated that borrowers who receive relief are not experiencing financial difficulty if they meet the following qualifying criteria: • The modification is in response to the National Emergency related to the COVID pandemic; • The borrower was current at the time the modification program was implemented; and • The modification is short-term We have elected to apply temporary relief under Section 4013 of the CARES Act to certain eligible short-term modifications and will not treat qualifying loan modifications as TDRs for accounting or disclosure purposes. Additionally, eligible short-term loan modifications subject to the practical expedient in the interagency guidance will not be treated as TDRs for accounting or disclosure purposes if they qualify. As of September 30, 2020, excluding any SBA guaranteed loans for which the government is making payments as provided for under the CARES Act, or single family loans that are guaranteed by FHA or VA, the Company has outstanding balances of $206 million on 375 loans that were approved for forbearance under this program. The Bank will exercise judgment in determining the risk rating for impacted borrowers and will not automatically adversely classify credits that are affected by COVID-19. The Bank also will not designate loans with deferrals granted due to COVID-19 as past due because of the deferral. Due to the short-term nature of the forbearance and other relief programs we are offering as a result of the COVID-19 pandemic, we expect that borrowers granted relief under these programs will generally not be reported as nonaccrual. This section reports results prior to the January 1, 2020 adoption of ASC 326 and is presented in accordance with previously applicable GAAP.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING ACTIVITIES	DERIVATIVES AND HEDGING ACTIVITIES: To reduce the risk of significant interest rate fluctuations on the value of certain assets and liabilities, such as certain mortgage LHFS or MSRs, the Company utilizes derivatives, such as forward sale commitments, futures, option contracts, interest rate swaps and interest rate swaptions as risk management instruments in its hedging strategy. Derivative transactions are measured in terms of notional amount, which is not recorded in the consolidated balance sheets. The notional amount is generally not exchanged and is used as the basis for interest and other contractual payments. Derivatives are reported at their respective fair values in the other assets or accounts payable and other liabilities line items on the consolidated balance sheets, with changes in fair value recognized in current period earnings. As permitted under U.S. GAAP, the Company nets derivative assets and liabilities when a legally enforceable master netting agreement exists between the Company and the derivative counterparty, which are documented under industry standard master agreements and credit support annexes. The Company's master netting agreements provide that following an uncured payment default or other event of default, the non-defaulting party may promptly terminate all transactions between the parties and determine a net amount due to be paid to, or by, the defaulting party. The collateral used under the Company's master netting agreements is typically cash, but securities may be used under agreements with certain counterparties. Receivables related to cash collateral that has been paid to counterparties is included in other assets. Payables related to cash collateral that has been received from counterparties is included in accounts payable and other liabilities. Interest is owed on amounts received from counterparties and we earn interest on cash paid to counterparties. Any securities pledged to counterparties as collateral remain on the consolidated balance sheets. The Company had liabilities of $6.9 million and $15.2 million in cash collateral received from counterparties and receivables of $16.7 million and $2.9 million in cash collateral paid to counterparties at September 30, 2020 and December 31, 2019, respectively. In addition, the Company periodically enters into certain commercial loan interest rate swap agreements in order to provide commercial loan customers the ability to convert from variable to fixed interest rates. Under these agreements, the Company enters into a variable-rate loan agreement with a customer in addition to a swap agreement. This swap agreement effectively converts the customer’s variable rate loan into a fixed rate. The Company then enters into a corresponding swap agreement with a third-party in order to offset its exposure on the variable and fixed components of the customer loan agreement. The interest rate swap agreements with the customers and third parties are marked to market in earnings. The notional amount of open interest rate swap agreements at September 30, 2020 and December 31, 2019 were $217 million and $144 million, respectively. For further information on the policies that govern derivative and hedging activities, see Note 1, Summary of Significant Accounting Policies, and Note 12, Derivatives and Hedging Activities, within our 2019 Annual Report on Form 10-K.

Advances of $3.1 million and $2.5 million were recorded in other assets as of September 30, 2020 and December 31, 2019, respectively. The Company has a unilateral right to repurchase certain delinquent or defaulted Ginnie Mae early buyout option ("GNMA EBO") pool loans it has previously sold, and, as required under GAAP, recognized a liability and an asset totaling $115 million and $9 million as of September 30, 2020 and December 31, 2019, respectively. Revenue from mortgage servicing, including the effects of derivative risk management instruments, consisted of the following.

(2) Principally reflects changes in market inputs, which include current market interest rates and prepayment model updates, both of which affect future prepayment speeds and cash flow projections. (3) Includes pre-tax income of $333 thousand and pre-tax loss of $941 thousand resulting from the sales of single family MSRs during the three and nine months ended September 30, 2019, respectively. All MSRs are initially measured and recorded at fair value at the time loans are sold. Single family MSRs are subsequently carried at fair value with changes in fair value reflected in earnings in the periods in which the changes occur, while multifamily and SBA MSRs are subsequently carried at the lower of amortized cost or fair value. The fair value of MSRs is determined based on the price that would be received to sell the MSRs in an orderly transaction between market participants at the measurement date. The Company determines fair value using a valuation model that calculates the net present value of estimated future cash flows. Estimates of future cash flows include contractual servicing fees, ancillary income and costs of servicing, the timing of which are impacted by assumptions, primarily expected prepayment speeds and discount rates, which relate to the underlying performance of the loans. The fair value measurement of MSRs is adjusted up or down depending on whether the underlying loan pool interest rate is at a premium, discount or par. Key economic assumptions used in measuring the fair value of capitalized single family MSRs were as follows. Three Months Ended September 30, Nine Months Ended September 30, (rates per annum) 2020 2019 2020 2019 Constant prepayment rate ("CPR") (1) 20.0% -30.0% 18.9 % 17.1%-30.0% 18.8 % Discount rate (2) 7.71 % 8.96 % 7.78 % 9.39 % (1) Represents an estimated lifetime average prepayment rate. (2) Discount rate is based on market observations. Key economic assumptions and the sensitivity of the current fair value for single family MSRs to immediate adverse changes in those assumptions were as follows. (dollars in thousands) At September 30, 2020 Fair value of single family MSR $ 47,018 Expected weighted-average life (in years) 4.01 Constant prepayment rate (1) 14.43 % Impact on fair value of 25 basis points adverse change in interest rates $ (2,638) Impact on fair value of 50 basis points adverse change in interest rates $ (5,141) Discount rate 8.11 % Impact on fair value of 100 basis points increase $ (1,063) Impact on fair value of 200 basis points increase $ (2,537) (1) Represents the expected lifetime average. These sensitivities are hypothetical and subject to key assumptions of the underlying valuation model. As the table above demonstrates, the Company's methodology for estimating the fair value of MSRs is highly sensitive to changes in key assumptions. For example, actual prepayment experience may differ and any difference may have a material effect on MSR fair value. Changes in fair value resulting from changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, in this table, the effect of a variation in a particular assumption on the fair value of the MSRs is calculated without changing any other assumption; in reality, changes in one factor may be associated with changes in another (for example, decreases in market interest rates may provide an incentive to refinance; however, this may also indicate a slowing economy and an increase in the unemployment rate, which reduces the number of borrowers who qualify for refinancing), which may magnify or counteract the sensitivities. Thus, any measurement of MSR fair value is limited by the conditions existing and assumptions made as of a particular point in time. Those assumptions may not be appropriate if they are applied to a different point in time. In March 2019, the Company successfully closed and settled two sales of the rights to service an aggregate of $14.3 billion in total unpaid principal balance of single family mortgage loans serviced for Fannie Mae, Ginnie Mae and Freddie Mac. These sales resulted in a $333 thousand pre-tax income and $941 thousand pre-tax loss from discontinued operations for the three and nine months ended September 30, 2019, respectively. The changes in single family MSRs measured at fair value are as follows. Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2020 2019 2020 2019 Beginning balance $ 47,804 $ 67,723 $ 68,109 $ 252,168 Additions and amortization: Originations 6,569 6,422 12,942 23,893 Sales — — — (176,944) Amortization (1) (4,401) (4,489) (12,246) (16,894) Net additions and amortization 2,168 1,933 696 (169,945) Changes in fair value assumptions (2) (2,954) (7,833) (21,787) (20,400) Ending balance $ 47,018 $ 61,823 $ 47,018 $ 61,823 (1) Represents changes due to collection/realization of expected cash flows and curtailments. (2) Principally reflects changes in model assumptions, including prepayment sped assumptions, which are primarily reflected by changes in mortgage interest rates. MSRs resulting from the sale of multifamily loans are recorded at fair value and subsequently carried at the lower of amortized cost or fair value. Multifamily MSRs are amortized in proportion to, and over, the estimated period the net servicing income will be collected. The changes in multifamily MSRs measured at the lower of amortized cost or fair value were as follows.

GUARANTEES	GUARANTEES: In the ordinary course of business, the Company sells and services loans through the Fannie Mae Multifamily DUS ® program and shares in the risk of loss with Fannie Mae under the terms of the DUS ® contracts (pari passu loss sharing agreement). Under such agreements, the Company and Fannie Mae share losses on a pro rata basis, where the Company is responsible for losses incurred up to one-third of the principal balance on each loan and with two-thirds of the loss covered by Fannie Mae. For loans that have been sold through this program, a liability is recorded for this loss sharing arrangement under the accounting guidance for guarantees. As of September 30, 2020 and December 31, 2019, the total unpaid principal balance of loans sold under this program was $1.6 billion and $1.5 billion, respectively. The Company's reserve liability related to this arrangement totaled $2.2 million and $2.8 million at September 30, 2020 and December 31, 2019, respectively. There were no actual losses incurred under this arrangement during the three and nine months ended September 30, 2020 and 2019. In the ordinary course of business, the Company sells residential mortgage loans to GSEs and other entities. In addition, the Company pools FHA-insured and VA-guaranteed mortgage loans into Ginnie Mae guaranteed mortgage-backed securities. The Company has made representations and warranties that the loans sold meet certain requirements. The Company may be required to repurchase mortgage loans or indemnify loan purchasers due to defects in the origination process of the loan, such as documentation errors, underwriting errors and judgments, early payment defaults and fraud. These obligations expose the Company to mark-to-market and credit losses on the repurchased mortgage loans after accounting for any mortgage insurance that we may receive. Generally, the maximum amount of future payments the Company would be required to make for breaches of these representations and warranties would be equal to the unpaid principal balance of such loans that are deemed to have defects that were sold to purchasers plus, in certain circumstances, accrued and unpaid interest on such loans and certain expenses. The Company does not typically receive repurchase requests from the FHA or VA. As an originator of FHA-insured or VA-guaranteed loans, the Company is responsible for obtaining the insurance with FHA or the guarantee with the VA. If loans are later found not to meet the requirements of FHA or VA, through required internal quality control reviews or through agency audits, the Company may be required to indemnify FHA or VA against losses. The Company's mortgage repurchase liability incorporates probable losses associated with such indemnification.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENT: Valuation Processes The Company has various processes and controls in place to ensure that fair value measurements are reasonably estimated. The Finance Committee of the Board provides oversight and approves the Company's Asset/Liability Management Policy ("ALMP"). The Company's ALMP governs, among other things, the application and control of the valuation models used to measure fair value. On a quarterly basis, the Company's Asset/Liability Management Committee ("ALCO") and the Finance Committee of the Board review significant modeling variables used to measure the fair value of the Company's financial instruments, including the significant inputs used in the valuation of single family MSRs. Additionally, ALCO periodically obtains an independent review of the MSR valuation process and procedures, including a review of the model architecture and the valuation assumptions. The Company obtains an MSR valuation from an independent valuation firm monthly to assist with the validation of the fair value estimate and the reasonableness of the assumptions used in measuring fair value. The Company's real estate valuations are overseen by the Company's appraisal department, which is independent of the Company's lending and credit administration functions. The appraisal department maintains the Company's appraisal policy and recommends changes to the policy subject to approval by the Company's Loan Committee and the Credit Committee of the Board. The Company's appraisals are prepared by independent third-party appraisers and the Company's internal appraisers. Single family appraisals are generally reviewed by the Company's single family loan underwriters. Single family appraisals with unusual, higher risk or complex characteristics, as well as commercial real estate appraisals, are reviewed by the Company's appraisal department. We obtain pricing from third party service providers for determining the fair value of a substantial portion of our investment securities AFS. We have processes in place to evaluate such third party pricing services to ensure information obtained and valuation techniques used are appropriate. For fair value measurements obtained from third party services, we monitor and review the results to ensure the values are reasonable and in line with market experience for similar classes of securities. While the inputs used by the pricing vendor in determining fair value are not provided and therefore unavailable for our review, we do perform certain procedures to validate the values received, including comparisons to other sources of valuation (if available), comparisons to other independent market data and a variance analysis of prices by Company personnel that are not responsible for the performance of the investment securities. Estimation of Fair Value Fair value is based on quoted market prices, when available. In cases where a quoted price for an asset or liability is not available, the Company uses valuation models to estimate fair value. These models incorporate inputs such as forward yield curves, loan prepayment assumptions, expected loss assumptions, market volatilities and pricing spreads utilizing market-based inputs where readily available. The Company believes its valuation methods are appropriate and consistent with those that would be used by other market participants. However, imprecision in estimating unobservable inputs and other factors may result in these fair value measurements not reflecting the amount realized in an actual sale or transfer of the asset or liability in a current market exchange. The following table summarizes the fair value measurement methodologies, including significant inputs and assumptions and classification of the Company's assets and liabilities. Asset/Liability class Valuation methodology, inputs and assumptions Classification Investment securities Investment securities AFS Observable market prices of identical or similar securities are used where available. Level 2 recurring fair value measurement. If market prices are not readily available, value is based on discounted cash flows using the following significant inputs: • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Level 3 recurring fair value measurement. LHFS Single family loans, excluding loans transferred from held for investment Fair value is based on observable market data, including: • Quoted market prices, where available • Dealer quotes for similar loans • Forward sale commitments Level 2 recurring fair value measurement. When not derived from observable market inputs, fair value is based on discounted cash flows, which considers the following inputs: • Benchmark yield curve • Estimated discount spread to the benchmark yield curve • Expected prepayment speeds Estimated fair value classified as Level 3.

There were no transfers between levels of the fair value hierarchy during the three and nine months ended September 30, 2020 and 2019. Level 3 Recurring Fair Value Measurements The Company's Level 3 recurring fair value measurements consist of investment securities AFS, single family MSRs, single family LHFI where fair value option was elected, certain single family LHFS and interest rate locks and purchase loan commitments, which are accounted for as derivatives. For information regarding fair value changes and activity for single family MSRs during the three and nine months ended September 30, 2020 and 2019, see Note 7, Mortgage Banking Operations of this Quarterly Report on Form 10-Q. The fair value of IRLCs considers several factors, including the fair value in the secondary market of the underlying loan resulting from the exercise of the commitment, the expected net future cash flows related to the associated servicing of the loan (referred to as the value of servicing) and the probability that the commitment will not be converted into a funded loan (referred to as a fall-out factor). The fair value of IRLCs on LHFS, while based on interest rates observable in the market, is highly dependent on the ultimate closing of the loans. The significance of the fall-out factor to the fair value measurement of an individual IRLC is generally highest at the time that the rate lock is initiated and declines as closing procedures are performed and the underlying loan gets closer to funding. The fall-out factor applied is based on historical experience. The value of servicing is impacted by a variety of factors, including prepayment assumptions, discount rates, delinquency rates, contractually specified servicing fees, servicing costs and underlying portfolio characteristics. Because these inputs are not observable in market trades, the fall-out factor and value of servicing are considered to be level 3 inputs. The fair value of IRLCs decreases in value upon an increase in the fall-out factor and increases in value upon an increase in the value of servicing. Changes in the fall-out factor and value of servicing do not increase or decrease based on movements in other significant unobservable inputs. The Company recognizes unrealized gains and losses from the time that an IRLC is initiated until the gain or loss is realized at the time the loan closes, which generally occurs within 30-90 days. For IRLCs that fall out, any unrealized gain or loss is reversed, which generally occurs at the end of the commitment period. The gains and losses recognized on IRLC derivatives generally correlates to volume of single family interest rate lock commitments made during the reporting period (after adjusting for estimated fallout) while the amount of unrealized gains and losses realized at settlement generally correlates to the volume of single family closed loans during the reporting period. The Company uses the discounted cash flow model to estimate the fair value of certain loans that have been transferred from held for sale to held for investment and single family LHFS when the fair value of the loans is not derived using observable market inputs. The key assumption in the valuation model is the implied spread to benchmark interest rate curve. The implied spread is not directly observable in the market and is derived from third party pricing which is based on market information from comparable loan pools. The fair value estimate of these certain single family loans that have been transferred from held for sale to held for investment and these certain single family LHFS are sensitive to changes in the benchmark interest rate which might result in a significantly higher or lower fair value measurement. The Company transferred certain loans from held for sale to held for investment. These loans were originated as held for sale loans where the Company had elected fair value option. The Company determined these loans to be level 3 recurring assets as the valuation technique included a significant unobservable input. The total amount of held for investment loans where fair value option election was made was $7.6 million and $3.5 million at September 30, 2020 and December 31, 2019, respectively.

These assets include certain LHFI and OREO that are carried at the lower of cost or fair value of the underlying collateral, less the estimated cost to sell. The estimated fair values of real estate collateral are generally based on internal evaluations and appraisals of such collateral, which use the market approach and income approach methodologies. The fair value of commercial properties are generally based on third-party appraisals that consider recent sales of comparable properties, including their income-generating characteristics, adjusted (generally based on unobservable inputs) to reflect the general assumptions that a market participant would make when analyzing the property for purchase. The Company uses a fair value of collateral technique to apply adjustments to the appraisal value of certain commercial LHFI that are collateralized by real estate. The Company uses a fair value of collateral technique to apply adjustments to the stated value of certain commercial LHFI that are not collateralized by real estate. During the three and nine months ended September 30, 2020 and 2019, the Company did not apply any adjustments to the appraisal value of OREO. Residential properties are generally based on unadjusted third-party appraisals. Factors considered in determining the fair value include geographic sales trends, the value of comparable surrounding properties as well as the condition of the property. These commercial and residential appraisal adjustments include management assumptions that are based on the type of collateral dependent loan and may increase or decrease an appraised value. Management adjustments vary significantly depending on the location, physical characteristics and income producing potential of each individual property. The quality and volume of market information available at the time of the appraisal can vary from period-to-period and cause significant changes to the nature and magnitude of the unobservable inputs used. Given these variations, changes in these unobservable inputs are generally not a reliable indicator for how fair value will increase or decrease from period to period. The following tables present assets that had changes in their recorded fair value during the three and nine months ended September 30, 2020 and 2019 and assets held at the end of the respective reporting period.

Restructuring and Related Activities [Abstract]
RESTRUCTURING	RESTRUCTURING: In 2019, we took steps to restructure our corporate operations in order to improve productivity and reduce total corporate expenses in light of a substantial reduction in the size and complexity of our Company and a lower growth plan going forward. Throughout 2019, we began executing this restructuring plan which included: • Simplifying the organizational structure by reducing management levels and management redundancy • Consolidating similar functions currently residing in multiple organizations • Renegotiating, where possible, our technology contracts • Identifying and eliminating redundant or unnecessary systems and services • Rationalizing staffing appropriate to recognize the significant changes in work volumes and company direction • Eliminating excess occupancy costs consistent with reduced personnel The costs incurred include severance, retention, facility related charges and consulting fees. These restructuring activities and related costs have continued into 2020. Also in 2019, in connection with the Board of Directors approved plan of exit or disposal of our stand-alone home loan-center based mortgage origination business and related mortgage servicing, the Company restructured certain aspects of its infrastructure and back office operations, which resulted in certain indirect severance and other employee related costs and impairment charges related to certain facilities and information systems. Restructuring charges primarily consist of facility-related costs and severance costs and are included in the occupancy and the compensation and benefits expense line items on our consolidated income statements in the applicable periods. The following tables summarize the restructuring charges recognized during the three and nine months ended September 30, 2020 and 2019 and the Company's net remaining liability balance at September 30, 2020.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (Policies)	9 Months Ended
	Sep. 30, 2020
Accounting Policies [Abstract]
Basis of Presentation	The Company's accounting and financial reporting policies conform with accounting principles generally accepted in the United States of America ("GAAP"). Inter-company balances and transactions have been eliminated in consolidation. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and revenues and expenses during the reporting periods and related disclosures.
Reclassifications	We have reclassified certain amounts in our consolidated financial statements for prior periods to conform with our current presentation.Immaterial Restatement: Subsequent to issuance of the June 30, 2020 financial statements, management concluded that purchases of and proceeds from the sale of Federal Home Loan Bank stock were incorrectly classified as financing activities, rather than investing activities, in the consolidated statements of cash flows. To correct this classification error, amounts previously reported for the purchases of and proceeds from the sale of Federal Home Loan Bank stock for the nine months ended September 30, 2019 as financing activities are reported as investing activities in the consolidated statement of cash flows.
Risks and Uncertainties	Risks and Uncertainties The worldwide spread of coronavirus (“COVID-19”) has created significant uncertainty in the global, national, regional and local economies. There have been no comparable recent events that provide guidance to the effects of the spread of COVID-19 as a global pandemic may have, and, as a result, the near-term, short-term and ultimate impacts of COVID-19 and the extent to which COVID-19 impacts the Company’s business, results of operations and financial condition will depend on future developments, which are highly uncertain and difficult to predict.
Share Repurchase Program	Share Repurchase ProgramAt the beginning of 2020, the Company had in place a share repurchase program under which the Company could purchase up to $8.1 million of its common stock. During the first quarter of 2020 and again in the third quarter of 2020, the Board authorized two additional programs, each for the repurchase of an additional $25 million of the Company’s common stock. During the first nine months of 2020, the Company repurchased 1,995,845 shares of its common stock at an average price of $26.03 per share.
Recent Accounting Developments	Recent Accounting Developments In December 2019, the Financial Accounting Standards Board ("FASB") issued ASU No 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 removes certain exceptions to the general principles in Topic 740 in Generally Accepted Accounting Principles. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company does not expect ASU 2019-12 to have a material effect on the Company’s current financial position, results of operations or financial statement disclosures. On January 1, 2020, the Company adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which replaces the incurred loss methodology ("ALLL") with an expected loss methodology that is referred to as the current expected credit losses ("CECL") methodology. The measurement of the expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures such as loan commitments. In addition, ASC 326 made changes to the accounting for credit losses for AFS debt securities. The Company adopted CECL using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet ("OBS") credit exposure. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a decrease of $3.7 million to the beginning balance of retained earnings on January 1, 2020 for the cumulative effect of adopting this guidance.
Allowance for Credit Losses	Allowance for Credit Losses for LHFI The allowance for credit losses ("ACL") for LHFI is a valuation account that is deducted from the loans amortized cost basis to present the net amount expected to be collected on the loans. Loan balances are charged off against the allowance when management believes the non-collectability of a loan balance is confirmed. Expected recoveries may not exceed the aggregate of amounts previously charged-off and expected to be charged-off. The ACL for LHFI, as reported in our consolidated balance sheets, is adjusted by a provision for credit losses and reduced by the charge-offs of loan amounts, net of recoveries. Management estimates the ACL balance using relevant available information from internal and external sources relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix or delinquency levels or other relevant factors. The credit loss estimation process involves procedures to appropriately consider the unique characteristics of its two loan portfolio segments, the consumer loan portfolio segment and the commercial loan portfolio segment. These two segments are further disaggregated into loan pools, the level at which credit risk is monitored. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Determining the appropriateness of the ACL is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall loan portfolio, based on the factors and forecasts then prevailing, may result in material changes in the ACL and provision for credit losses in those future periods. Credit Loss Measurement The allowance level is influenced by current conditions related to loan volumes, loan asset quality ratings ("AQR") migration or delinquency status, historic loss experience and other conditions influencing loss expectations, such as reasonable and supportable forecasts of economic conditions. The methodology for estimating the amount of expected credit losses has two basic components: first, a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics and second an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. Loans that Share Similar Risk Characteristics with Other Loans In estimating the component of the ACL, for loans that share similar risk characteristics with other loans, loans are segregated into loan pools based on similar risk characteristics, like product types or areas of risk concentration. The Company's ACL model methodology is to build a reserve rate using historical life of loan default rates combined with assessments of current loan portfolio information and forecasted economic environment and business cycle information. The model uses statistical analysis to determine the life of loan default rates for the quantitative component and analyzes qualitative factors (Q-Factors) that assess the current loan portfolio conditions and forecasted economic environment. Below is the general overview our ACL model. Historical Loss Rate The Company chose to analyze loan data from a full economic cycle, to the extent that data was available, to calculate life of loan loss rates. Based on the current economic environment and available loan level data, it was determined the Loss Horizon Period (LHP) should begin prior to the economic recession that began in 2007. The Company plans to monitor and review the LHP on an annual basis to determine appropriate time frames to be included based on economic indicators. Under CECL, the Company groups pools of loans by similar risk characteristics. Using these pools, sub-pools are established at a more granular level incorporating delinquency status and original FICO or original LTV (for consumer loans) and risk ratings (for commercial loans). Using the pool and sub-pool structure, cohorts are established historically on a quarterly basis containing the population in these sets as of that point in time. After the establishment of these cohorts, the loans within the cohorts are then tracked from that point forward to establish long-term Probability of Default ("PD") at the sub-pool level and Loss Given Default ("LGD") for the pool level. These historical cohorts and their PD/LGD outcomes are then averaged together to establish expected PDs and LGDs for each sub-pool. Once historical cohorts are established, the loans in the cohort are tracked moving forward for default events. The Company has defined default events as the first dollar of loss. If a loan in the cohort has experienced a default event over the LHP then the balance of the loan at the time of cohort establishment becomes part of the numerator of the PD calculation. The Loss Given Probability of Default ("LGPD") or Expected Loss ("EL") is the weighted average PD for each sub-pool cohort times the average LGD for each pool. The output from the model then is a series of EL rates for each loan sub-pool, which are applied to the related outstanding balances for each loan sub-pool to determine the ACL reserve based on historical loss rates. Q-Factors The Q-Factors adjust the expected historic loss rates for current and forecasted conditions that are not provided for in the historical loss information. The Company has established a methodology for adjusting historical expected loss rates based on these more recent or forecasted changes. The Q-Factor methodology is based on a blend of quantitative analysis and management judgment and reviewed on a quarterly basis. Each of the thirteen factors in the FASB standard were analyzed for common risk characteristics and grouped into seven consolidated Q-Factors as listed below. Qualitative Factor Financial Instruments - Credit Losses Portfolio Credit Quality The borrower's financial condition, credit rating, credit score, asset quality or business prospects The borrower's ability to make scheduled interest or principal payments The volume and severity of past due financial assets and the volume and severity of adversely classified or rated financial assets Remaining Payments The remaining payment terms of the financial assets The remaining time to maturity and the timing and extent of prepayments on the financial assets Volume & Nature The nature and volume of the entity's financial assets Collateral Values The value of underlying collateral on financial assets in which the collateral-dependent practical expedient has not been utilized Economic The environmental factors of a borrower and the areas in which the entity's credit is concentrated, such as: Changes and expected changes in national, regional and local economic and business conditions and developments in which the entity operates, including the condition and expected condition of various market segments Credit Culture The entity's lending policies and procedures, including changes in lending strategies, underwriting standards, collection, write-off and recovery practices, as well as knowledge of the borrower's operations or the borrower's standing in the community The quality of the entity's credit review system The experience, ability and depth of the entity's management, lending staff, and other relevant staff Business Environment The environmental factors of a borrower and the areas in which the entity's credit is concentrated, such as: Regulatory, legal, or technological environment to which the entity has exposure The environmental factors of a borrower and the areas in which the entity's credit is concentrated, such as: Changes and expected changes in the general market condition of either the geographical area or the industry to which the entity has exposure An eighth Q-Factor, Management Overlay, has been created to allow the Bank to adjust specific pools when conditions exist that were not contemplated in the model design that warrant an adjustment. The economic downturn caused by the COVID-19 pandemic and resulting accounting treatment of forbearances is an example of such a condition. The Company has chosen two years as the forecast period based on management judgment and has determined that reasonable and supportable forecasts should be made for two of the Q-Factors: Economic and Collateral values. Management has assigned weightings for each qualitative factor as well as individual metrics within each qualitative factor as to the relative importance of that factor or metric specific to each portfolio type. The Q-Factors above are evaluated using a seven-point scale ranging from significant improvement to significant deterioration. The CECL Q-Factor methodology bounds the Q-Factor adjustments by a minimum and maximum range, based on the Bank’s own historical expected loss rates for each respective pool. The rating of the Q-Factor on the seven-point scale, along with the allocated weight, determines the final expected loss adjustment. The model is constructed so that the total of the Q-Factor adjustments plus the current expected loss rate cannot exceed the maximum or minimum two-year loss rate for that pool, which is aligned with the Bank's chosen forecast period. Loss rates beyond two years are not adjusted in the Q-Factor process and the model reverts to the historical mean loss rates. Management Overlays are not bounded by the historical maximums. Quarterly, loan data is gathered to update the portfolio metrics analyzed in the Q-Factor model. The model is updated with current data and applicable forecasts, then the results are reviewed by management. After consensus is reached on all Q-Factor ratings, the results are input into the Q-Factor model and applied to the pooled loans which are reviewed to determine the adequacy of the reserve. Additional details describing the model by portfolio segment are below: Consumer Loan Portfolio The consumer loan portfolio segment is comprised of the single family and home equity loan classes, which are underwritten after evaluating a borrower's capacity, credit and collateral. Other consumer loans are grouped with home equity loans. Capacity refers to a borrower's ability to make payments on the loan. Several factors are considered when assessing a borrower's capacity, including the borrower's employment, income, current debt, assets and level of equity in the property. Credit refers to how well a borrower manages current and prior debts as documented by a credit report that provides credit scores and current and past information about the borrower's credit history. Collateral refers to the type and use of property, occupancy and market value. Property appraisals are obtained to assist in evaluating collateral. Loan-to-property value and debt-to-income ratios, loan amount and lien position are considered in assessing whether to originate a loan. These borrowers are particularly susceptible to downturns in economic trends such as conditions that negatively affect housing prices, demand for housing and levels of unemployment. Consumer Loan Portfolio Segment Estimated Loss Rate Model Under CECL, the Bank utilizes pools of loans that are grouped by similar risk characteristics: Single Family and Home Equity Loans which includes Consumer loans. Sub-Pools are established at a more granular level for the calculation of PDs, incorporating delinquency status, original FICO and original LTV. Consumer portfolio cohorts are established by grouping each ACL sub-pool at a point in time. Once historical cohorts are established, the loans in the cohort are tracked moving forward for default events. The Q-Factors adjust the expected historic loss rates for current and forecasted conditions that are not provided for in the historical loss information. For Single Family loans all Q-Factors noted above are evaluated. For the Home Equity and Consumer loans, collateral values are not evaluated as the Bank has determined the FICO score trends are a more relevant predictor of default than current collateral value for those types of loans. These factors are evaluated based on current conditions and forecasts (as applicable), using a seven-point scale ranging from significant improvement to significant deterioration. Commercial Loan Portfolio The commercial loan portfolio segment is comprised of the non-owner occupied commercial real estate, multifamily, construction and land development, owner occupied commercial real estate and commercial business loan classes, whose underwriting standards consider the factors described for single family and home equity loan classes as well as others when assessing the borrower's and associated guarantors or other related party’s financial position. These other factors include assessing liquidity, net worth, leverage, other outstanding indebtedness of the borrower, the quality and reliability of cash expected to flow through the borrower (including the outflow to other lenders) and prior known experiences with the borrower. This information is used to assess financial capacity, profitability and experience. Ultimate repayment of these loans is sensitive to interest rate changes, general economic conditions, liquidity and availability of long-term financing. Commercial Loan Portfolio Segment Loss Rate Model The Bank maintained loan classes above but has subdivided the construction and land development, which includes lot, land and acquisition and development loans, into the following ACL reporting pools to more accurately group risk characteristics: Multifamily, Commercial Real Estate, Single Family and Single Family construction to permanent. ACL sub-pools are established at a more granular level for the calculation of PDs, utilizing risk rating. As outlined in the Bank’s policies, commercial loans pools are non-homogenous and are regularly assessed for credit quality. For purposes of CECL, loans are sub-pooled according to the following AQR Ratings: • 1-6: These loans meet the definition of “Pass" assets. They are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less costs to acquire and sell in a timely manner, of any underlying collateral. The Bank further uses the available AQR ratings for components of the sub-pools. • 7: These loans meet the regulatory definition of “Special Mention.” They contain potential weaknesses, that if uncorrected may result in deterioration of the likelihood of repayment or in the Bank’s credit position. • 8: These loans meet the regulatory definition of “Substandard”. They are inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged, if any. They have well-defined weaknesses and have unsatisfactory characteristics causing unacceptable levels of risk. Commercial segment cohorts are established by grouping each ACL sub-pool at a point in time. Once historical cohorts are established, the loans in the cohort are tracked moving forward for default events. The Q-Factors adjust the expected historic loss rates for current and forecasted conditions that are not provided for in the historical loss information. All the Q-Factors noted above are evaluated for Commercial portfolio loans except for Commercial Business and Owner Occupied Commercial Real Estate ("CRE") loans which exclude the collateral values Q-Factor. The Company has determined that these loans are primarily underwritten by evaluating the cash flow of the business and not the underlying collateral. Factors above are evaluated based on current conditions and forecasts (as applicable), using a seven-point scale ranging from significant improvement to significant deterioration. Loans That Do Not Share Risk Characteristics with Other Loans For a loan that does not share risk characteristics with other loans, expected credit loss is measured on net realizable value that is the difference between the discounted value of the expected future cash flows, based on the original effective interest rate and the amortized cost basis of the loan. For these loans, we recognize expected credit loss equal to the amount by which the net realizable value of the loan is less than the amortized cost basis of the loan (which is net of previous charge-offs and deferred loan fees and costs), except when the loan is collateral dependent, which is when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In these cases, expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral. The fair value of the collateral is adjusted for the estimated costs to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. The starting point for determining the fair value of collateral is through obtaining external appraisals. Generally, collateral values for collateral dependent loans are updated every twelve months, either from external third parties or in-house certified appraisers. A third-party appraisal is required at least annually for substandard loans and OREO. Third party appraisals are obtained from a pre-approved list of independent, third party, local appraisal firms. Approval and addition to the list is based on experience, reputation, character, consistency and knowledge of the respective real estate market. Generally, appraisals are internally reviewed by the appraisal services group to ensure the quality of the appraisal and the expertise and independence of the appraiser. For performing consumer segment loans secured by real estate that are classified as collateral dependent, the Bank determines the fair value estimates quarterly using automated valuation services. Once the expected loss amount is determined, an allowance is recorded equal to the calculated expected credit loss and included in the ACL. If the calculated expected loss is determined to be permanent or not recoverable, the expected credit loss will be charged off. Factors considered by management in determining if the expected credit loss is permanent or not recoverable include whether management judges the loan to be uncollectible, repayment is deemed to be protracted beyond reasonable time frames, or the loss becomes evident owing to the borrower's lack of assets or, for single family loans, the loan is 180 days or more past due unless both well-secured and in the process of collection. Allowance for Credit Losses for Off-Balance Sheet Credit Exposures The Bank estimates expected credit losses over the contractual period in which the Bank is exposed to risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Bank. Reserves are required for OBS credit exposures that are not unconditionally cancellable. The allowance for credit losses on unfunded loan commitments is based on an estimate of unfunded commitment utilization over the life of the loan, applying the EL to the estimated utilization balance as of the reporting period. As these estimated credit loss calculations are similar to the funded LHFI they share similar risks plus the additional risk from estimating commitment utilization. Allowance for Credit Losses for Other Financial Instruments The Company evaluates AFS securities in an unrealized loss position, using a qualitative approach, at the end of each quarter to determine whether the decline in value is temporary or permanent. An unrealized loss exists when the fair value of an individual security is less than its amortized cost basis. When qualitative factors indicate that a credit loss may exist, the Company compares the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. The Company recognizes an ACL measured as the difference between the present value of expected cash flows and the amortized cost basis of the security, limited by the amount that the security’s fair value is less than its amortized cost basis. The Company does not believe any of these securities that were in an unrealized loss position at September 30, 2020 represent a credit loss impairment.
Derivatives and Hedging Activities	To reduce the risk of significant interest rate fluctuations on the value of certain assets and liabilities, such as certain mortgage LHFS or MSRs, the Company utilizes derivatives, such as forward sale commitments, futures, option contracts, interest rate swaps and interest rate swaptions as risk management instruments in its hedging strategy. Derivative transactions are measured in terms of notional amount, which is not recorded in the consolidated balance sheets. The notional amount is generally not exchanged and is used as the basis for interest and other contractual payments. Derivatives are reported at their respective fair values in the other assets or accounts payable and other liabilities line items on the consolidated balance sheets, with changes in fair value recognized in current period earnings. As permitted under U.S. GAAP, the Company nets derivative assets and liabilities when a legally enforceable master netting agreement exists between the Company and the derivative counterparty, which are documented under industry standard master agreements and credit support annexes. The Company's master netting agreements provide that following an uncured payment default or other event of default, the non-defaulting party may promptly terminate all transactions between the parties and determine a net amount due to be paid to, or by, the defaulting party.
Mortgage Banking Operations	All MSRs are initially measured and recorded at fair value at the time loans are sold. Single family MSRs are subsequently carried at fair value with changes in fair value reflected in earnings in the periods in which the changes occur, while multifamily and SBA MSRs are subsequently carried at the lower of amortized cost or fair value. The fair value of MSRs is determined based on the price that would be received to sell the MSRs in an orderly transaction between market participants at the measurement date. The Company determines fair value using a valuation model that calculates the net present value of estimated future cash flows. Estimates of future cash flows include contractual servicing fees, ancillary income and costs of servicing, the timing of which are impacted by assumptions, primarily expected prepayment speeds and discount rates, which relate to the underlying performance of the loans.
Fair Value Measurement	Valuation Processes The Company has various processes and controls in place to ensure that fair value measurements are reasonably estimated. The Finance Committee of the Board provides oversight and approves the Company's Asset/Liability Management Policy ("ALMP"). The Company's ALMP governs, among other things, the application and control of the valuation models used to measure fair value. On a quarterly basis, the Company's Asset/Liability Management Committee ("ALCO") and the Finance Committee of the Board review significant modeling variables used to measure the fair value of the Company's financial instruments, including the significant inputs used in the valuation of single family MSRs. Additionally, ALCO periodically obtains an independent review of the MSR valuation process and procedures, including a review of the model architecture and the valuation assumptions. The Company obtains an MSR valuation from an independent valuation firm monthly to assist with the validation of the fair value estimate and the reasonableness of the assumptions used in measuring fair value. The Company's real estate valuations are overseen by the Company's appraisal department, which is independent of the Company's lending and credit administration functions. The appraisal department maintains the Company's appraisal policy and recommends changes to the policy subject to approval by the Company's Loan Committee and the Credit Committee of the Board. The Company's appraisals are prepared by independent third-party appraisers and the Company's internal appraisers. Single family appraisals are generally reviewed by the Company's single family loan underwriters. Single family appraisals with unusual, higher risk or complex characteristics, as well as commercial real estate appraisals, are reviewed by the Company's appraisal department. We obtain pricing from third party service providers for determining the fair value of a substantial portion of our investment securities AFS. We have processes in place to evaluate such third party pricing services to ensure information obtained and valuation techniques used are appropriate. For fair value measurements obtained from third party services, we monitor and review the results to ensure the values are reasonable and in line with market experience for similar classes of securities. While the inputs used by the pricing vendor in determining fair value are not provided and therefore unavailable for our review, we do perform certain procedures to validate the values received, including comparisons to other sources of valuation (if available), comparisons to other independent market data and a variance analysis of prices by Company personnel that are not responsible for the performance of the investment securities. Estimation of Fair Value Fair value is based on quoted market prices, when available. In cases where a quoted price for an asset or liability is not available, the Company uses valuation models to estimate fair value. These models incorporate inputs such as forward yield curves, loan prepayment assumptions, expected loss assumptions, market volatilities and pricing spreads utilizing market-based inputs where readily available. The Company believes its valuation methods are appropriate and consistent with those that would be used by other market participants. However, imprecision in estimating unobservable inputs and other factors may result in these fair value measurements not reflecting the amount realized in an actual sale or transfer of the asset or liability in a current market exchange. The following table summarizes the fair value measurement methodologies, including significant inputs and assumptions and classification of the Company's assets and liabilities. Asset/Liability class Valuation methodology, inputs and assumptions Classification Investment securities Investment securities AFS Observable market prices of identical or similar securities are used where available. Level 2 recurring fair value measurement. If market prices are not readily available, value is based on discounted cash flows using the following significant inputs: • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Level 3 recurring fair value measurement. LHFS Single family loans, excluding loans transferred from held for investment Fair value is based on observable market data, including: • Quoted market prices, where available • Dealer quotes for similar loans • Forward sale commitments Level 2 recurring fair value measurement. When not derived from observable market inputs, fair value is based on discounted cash flows, which considers the following inputs: • Benchmark yield curve • Estimated discount spread to the benchmark yield curve • Expected prepayment speeds Estimated fair value classified as Level 3. Mortgage servicing rights Single family MSRs For information on how the Company measures the fair value of its single family MSRs, including key economic assumptions and the sensitivity of fair value to changes in those assumptions, see Note 7 , Mortgage Banking Operations . Level 3 recurring fair value measurement. Derivatives Eurodollar futures Fair value is based on closing exchange prices. Level 1 recurring fair value measurement. Interest rate swaps Fair value is based on quoted prices for identical or similar instruments, when available. Level 2 recurring fair value measurement. Interest rate lock commitments The fair value considers several factors including: • Fair value of the underlying loan based on quoted prices in the secondary market, when available. • Value of servicing • Fall-out factor Level 3 recurring fair value measurement.

Fair value measurement methodologies	The following table summarizes the fair value measurement methodologies, including significant inputs and assumptions and classification of the Company's assets and liabilities. Asset/Liability class Valuation methodology, inputs and assumptions Classification Investment securities Investment securities AFS Observable market prices of identical or similar securities are used where available. Level 2 recurring fair value measurement. If market prices are not readily available, value is based on discounted cash flows using the following significant inputs: • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Level 3 recurring fair value measurement. LHFS Single family loans, excluding loans transferred from held for investment Fair value is based on observable market data, including: • Quoted market prices, where available • Dealer quotes for similar loans • Forward sale commitments Level 2 recurring fair value measurement. When not derived from observable market inputs, fair value is based on discounted cash flows, which considers the following inputs: • Benchmark yield curve • Estimated discount spread to the benchmark yield curve • Expected prepayment speeds Estimated fair value classified as Level 3. Mortgage servicing rights Single family MSRs For information on how the Company measures the fair value of its single family MSRs, including key economic assumptions and the sensitivity of fair value to changes in those assumptions, see Note 7 , Mortgage Banking Operations . Level 3 recurring fair value measurement. Derivatives Eurodollar futures Fair value is based on closing exchange prices. Level 1 recurring fair value measurement. Interest rate swaps Fair value is based on quoted prices for identical or similar instruments, when available. Level 2 recurring fair value measurement. Interest rate lock commitments The fair value considers several factors including: • Fair value of the underlying loan based on quoted prices in the secondary market, when available. • Value of servicing • Fall-out factor Level 3 recurring fair value measurement.
