Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Accounting

The accompanying unaudited condensed consolidated financial statements include the accounts of Banner Corporation (the Company or Banner), a bank holding company incorporated in the State of Washington and its wholly-owned subsidiaries, Banner Bank and Islanders Bank (the Banks).

These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (SEC). In preparing these financial statements, the Company has evaluated events and transactions subsequent to September 30, 2020 for potential recognition or disclosure. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information and note disclosures have been condensed or omitted pursuant to the rules and regulations of the SEC and the accounting standards for interim financial statements. Certain reclassifications have been made to the 2019 Consolidated Financial Statements and/or schedules to conform to the 2020 presentation. These reclassifications may have affected certain ratios for the prior periods. The effect of these reclassifications is considered immaterial. All significant intercompany transactions and balances have been eliminated.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements. Various elements of the Company’s accounting policies, by their nature, are inherently subject to estimation techniques, valuation assumptions and other subjective assessments. In particular, management has identified several accounting policies that, due to the judgments, estimates and assumptions inherent in those policies, are significant to an understanding of Banner’s financial statements. These policies relate to (i) the methodology for the recognition of interest income, (ii) determination of the provision and allowance for credit losses, (iii) the valuation of financial assets and liabilities recorded at fair value (iv) the valuation of intangibles, such as goodwill, core deposit intangibles (CDI) and mortgage servicing rights, (v) the valuation of real estate held for sale, (vi) the valuation of assets acquired and liabilities assumed in business combinations and subsequent recognition of related income and expense, and (vii) the valuation or recognition of deferred tax assets and liabilities. These policies and judgments, estimates and assumptions are described in greater detail in subsequent notes to the Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations (Critical Accounting Policies) in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC (2019 Form 10-K).  There have been no significant changes in our application of these accounting policies during the first nine months of 2020, except for the change related to the adoption of Financial Instruments - Credit Losses (Topic 326) as described in below and Note 2.

The information included in this Form 10-Q should be read in conjunction with our 2019 Form 10-K.  Interim results are not necessarily indicative of results for a full year or any other interim period.

As a result of the adoption of Financial Instruments—Credit Losses (Topic 326) on January 1, 2020, the Company has updated the following significant accounting policies.

Securities: Debt securities are classified as held-to-maturity when the Company has the ability and positive intent to hold them to maturity.  Debt securities classified as available-for-sale are available for future liquidity requirements and may be sold prior to maturity.  Debt securities classified as trading are also available for future liquidity requirements and may be sold prior to maturity.  Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities.  Debt securities classified as held-to-maturity are carried at cost, net of the allowance for credit losses- securities, adjusted for amortization of premiums to the earliest callable date and accretion of discounts to maturity.  Debt securities classified as available-for-sale are measured at fair value.  Unrealized holding gains and losses on debt securities classified as available-for-sale are excluded from earnings and are reported net of tax as accumulated other comprehensive income (AOCI), a component of shareholders’ equity, until realized.  Debt securities classified as trading are also measured at fair value.  Unrealized holding gains and losses on securities classified as trading are included in earnings.  (See Note 9 for a more complete discussion of accounting for the fair value of financial instruments.)  Realized gains and losses on sale are computed on the specific identification method and are included in earnings on the trade date sold.

If debt securities were transferred from held-to-maturity to available-for-sale, unrealized gains or losses from the time of transfer would be accreted or amortized over the remaining life of the debt security based on the amount and timing of future estimated cash flows.  The accretion or amortization of the amount recorded in AOCI increases the carrying value of the investment and does not affect earnings.

Equity securities are measured at fair value with changes in the fair value recognized through net income.

Allowance for Credit Losses - Securities: Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. The Company’s held-to maturity portfolio contains mortgage-backed securities issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The Company’s held-to-maturity portfolio also contains municipal bonds that are typically rated by major rating agencies as Aa or better. The Company has never incurred a loss on a municipal bond, therefore the expectation of credit losses on these securities is insignificant. The Company uses industry historical credit loss information adjusted for current conditions to establish the allowance for credit losses on the municipal bond portfolio. Less than 2% of the Company’s held-to-maturity portfolio are community development bonds representing pools of one- to four-family loans. The expected credit losses on these bonds is similar to Banner’s one- to four-family residential loan portfolio.

For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before recovering its cost basis, the entire impairment loss would be recognized in earnings.  If the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized costs, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security.  Projected cash flows are discounted by the current effective interest rate.  If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. The remaining impairment related to all other factors, the difference between the present value of the cash flows expected to be collected and fair value, is recognized as a charge to AOCI.  

Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management believes the non-collectability of an available-for-sale security is confirmed or when either of the criteria regarding intent of requirement to sell is met.

Loans Receivable:  The Banks originate residential one- to four-family and multifamily mortgage loans for both portfolio investment and sale in the secondary market.  The Banks also originate construction and land development, commercial real estate, commercial business, agricultural and consumer loans for portfolio investment.  Loans receivable not designated as held for sale are recorded at amortized cost, net of the allowance for credit losses. Amortized cost is the principal amount outstanding, net of deferred fees, discounts and premiums.  Accrued interest on loans is reported in accrued interest receivable on the consolidated statements of financial condition. Premiums, discounts and deferred loan fees are amortized to maturity using the level-yield methodology.

Loans Held for Sale. Residential one- to four-family and multifamily mortgage loans originated with the intent to be sold in the secondary market are considered held for sale. Residential one- to four-family loans under best effort delivery commitments are carried at the lower of aggregate cost or estimated market value. Residential one- to four-family loans under mandatory delivery commitments are carried at fair value in order to match changes in the value of the loans with the value of the related economic hedges on the loans. Fair values for residential mortgage loans held for sale are determined by comparing actual loan rates to current secondary market prices for similar loans. The multifamily held-for-sale loans are carried at fair value in order to match changes in the value of the loans with the value of the related economic hedges on the loans. Fair values for multifamily loans held for sale are calculated based on discounted cash flows using a discount rate that is a combination of market spreads for similar loan types added to selected index rates. Net unrealized losses on loans held for sale that are carried at lower of cost or market are recognized through the valuation allowance by charges to income.  Non-refundable fees and direct loan origination costs related to loans held for sale are recognized as part of the cost basis of the loan. Gains and losses on sales of loans held for sale are determined using the aggregate method and are recorded in the mortgage banking operations component of non-interest income.

Loans Acquired in Business Combinations: Loans acquired in business combinations are recorded at their fair value at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either purchased credit-deteriorated or purchased non-credit-deteriorated. Purchased credit-deteriorated (PCD) loans have experienced more than insignificant credit deterioration since origination. For PCD loans, an allowance for credit losses is determined at the acquisition date using the same measurement methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The loan’s fair value grossed up for the allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through a provision for credit losses.

For purchased non-credit-deteriorated loans, the difference between the fair value and unpaid principal balance of the loan at the acquisition date is amortized or accreted to interest income over the life of the loans. While credit discounts are included in the determination of the fair value for non-credit-deteriorated loans, since these discounts are expected to be accreted over the life of the loans, they cannot be used to offset the allowance for credit losses that must be recorded at the acquisition date. As a result, an allowance for credit losses is determined at the acquisition date using the same methodology as other loans held for investment and is recognized as a provision for credit losses in the statement of operations. Any subsequent deterioration (improvement) in credit quality is recognized by recording (recapturing) a provision for credit losses.

Income Recognition on Nonaccrual Loans and Securities:  Interest on loans and securities is accrued as earned unless management doubts the collectability of the asset or the unpaid interest.  Interest accruals on loans are generally discontinued when loans become 90 days past due for payment of interest or principal and the loans are then placed on nonaccrual status.  Loans are reported as past due when installment payments, interest payments, or maturity payments are past due based on contractual terms. All previously accrued but uncollected interest is written off by reversing interest income upon transfer to nonaccrual status.  For any future payments collected, interest income is recognized only upon management’s assessment that there is a strong likelihood that the full amount of a loan will be repaid or recovered.  A loan may be put on nonaccrual status sooner than this policy would dictate if, in management’s judgment, the interest may be uncollectable.  While less common, similar interest reversal and nonaccrual treatment is applied to investment securities if their ultimate collectability becomes questionable. Loans modified due to the COVID-19 pandemic are considered current if they are less than 30 days past due on the contractual payments at the time the loan modification program was put in place and therefore continue to accrue interest unless the interest is being waived.

Provision and Allowance for Credit Losses - Loans:  The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. The Banks have elected to exclude accrued interest receivable from the amortized cost basis in their estimate of the allowance for credit losses. The provision for credit losses reflects the amount required to maintain the allowance for credit losses at an appropriate level based upon management’s evaluation of the adequacy of collective and individual loss reserves.  The Company has established systematic methodologies for the determination of the adequacy of the Company’s allowance for credit losses.  The methodologies are set forth in a formal policy and take into consideration the need for a valuation allowance for loans evaluated on a collective (pool) basis which have similar risk characteristics as well as allowances that are tied to individual loans that do not share risk characteristics.  The Company increases its allowance for credit losses by charging provisions for credit losses on its consolidated statement of operations. Losses related to specific assets are applied as a reduction of the carrying value of the assets and charged against the allowance for credit loss reserve when management believes the non-collectability of a loan balance is confirmed.  Recoveries on previously charged off loans are credited to the allowance for credit losses.  

Management estimates the allowance for credit losses using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The allowance for credit losses is maintained at a level sufficient to provide for expected credit losses over the life of the loan based on evaluating historical credit loss experience and making adjustments to historical loss information for differences in the specific risk characteristics in the current loan portfolio.  These factors include, among others, changes in the size and composition of the loan portfolio, differences in underwriting standards, delinquency rates, actual loss experience and current economic conditions.

The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. In estimating the component of the allowance for credit losses for loans that share common risk characteristics, loans are pooled based on loan type and areas of risk concentration. For loans evaluated collectively, the allowance for credit losses is calculated using life of loan historical losses adjusted for economic forecasts and current conditions.

For commercial real estate, multifamily real estate, construction and land, commercial business and agricultural loans with risk rating segmentation, historical credit loss assumptions are estimated using a model that categorizes loan pools based on loan type and risk rating. For one- to four- family residential loans, historical credit loss assumptions are estimated using a model that categorizes loan pools based on loan type and delinquency status. These models calculate an expected life-of-loan loss percentage for each loan category by calculating the probability of default, based on the migration of loans from performing to loss by risk rating or delinquency categories using historical life-of-loan analysis and the severity of loss, based on the aggregate net lifetime losses incurred for each loan pool. For commercial real estate, commercial business, and consumer loans without risk rating segmentation, historical credit loss assumptions are estimated using a model that calculates an expected life-of-loan loss percentage for each loan category by considering the historical cumulative losses based on the aggregate net lifetime losses incurred for each loan pool. The model captures historical loss data back to the first quarter of 2008. For loans evaluated collectively, management uses economic indicators to adjust the historical loss rates so that they better reflect management’s expectations of future conditions over the remaining lives of the loans in the portfolio based on reasonable and supportable forecasts. These economic indicators are selected based on correlation to the Company’s historical credit loss experience and are evaluated for each loan category. The economic indicators evaluated include unemployment, gross domestic product, real estate price indices and growth, yield curve spreads, treasury yields, the corporate yield, the market volatility index, the Dow Jones index, the consumer confidence index, and the prime rate. Management considers various economic scenarios and forecasts when evaluating the economic indicators and probability weights the various scenarios to arrive at the forecast that most reflects management’s expectations of future conditions. The allowance for credit losses is then adjusted for the period in which those forecasts are considered to be reasonable and supportable. To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made, the adjustments discontinue to be applied so that the model reverts back to the historical loss rates using a straight line reversion method. Management selected an initial reasonable and supportable forecast period of 12 months with a reversion period of 12 months. Both the reasonable and supportable forecast period and the reversion period are periodically reviewed by management.

Further, for loans evaluated collectively, management also considers qualitative and environmental factors for each loan category to adjust for differences between the historical periods used to calculate historical loss rates and expected conditions over the remaining lives of the loans in the portfolio. In determining the aggregate adjustment needed management considers the financial condition of the borrowers, the nature and volume of the loans, the remaining terms and the extent of prepayments on the loans, the volume and severity of past due and classified loans as well as the value of the underlying collateral on loans in which the collateral dependent practical expedient has not been used. Management also considers the Company’s lending policies, the quality of the Company’s credit review system, the quality of the Company’s

management and lending staff, and the regulatory and economic environments in the areas in which the Company’s lending activities are concentrated.

Loans that do not share risk characteristics with other loans in the portfolio that are individually evaluated for impairment are not included in the collective evaluation.  Factors involved in determining whether a loan should be individually evaluated include, but are not limited to, the financial condition of the borrower and the value of the underlying collateral.  Expected credit losses for loans evaluated individually are measured based on the present value of expected future cash flows discounted at the loan’s original effective interest rate or when the Banks determine that foreclosure is probable, the expected credit loss is measured based on the fair value of the collateral as of the reporting date, less estimated selling costs, as applicable. As a practical expedient, the Banks measure the expected credit loss for a loan using the fair value of the collateral, if repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the Banks' assessment as of the reporting date.

In both cases, if the fair value of the collateral is less than the amortized cost basis of the loan, the Banks will recognize an allowance as the difference between the fair value of the collateral, less costs to sell (if applicable), at the reporting date and the amortized cost basis of the loan. If the fair value of the collateral exceeds the amortized cost basis of the loan, any expected recovery added to the amortized cost basis will be limited to the amount previously charged-off. Subsequent changes in the expected credit losses for loans evaluated individually are included within the provision for credit losses in the same manner in which the expected credit loss initially was recognized or as a reduction in the provision that would otherwise be reported.

Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Banks.

Some of the Banks’ loans are reported as troubled debt restructures (TDRs).  Loans are reported as TDRs when the Banks grant a concession(s) to a borrower experiencing financial difficulties that it would not otherwise consider.  Examples of such concessions include forgiveness of principal or accrued interest, extending the maturity date(s) or providing a lower interest rate than would be normally available for a transaction of similar risk.  The allowance for credit losses on a TDR is determined using the same method as all other loans held for investment, except when the value of the concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method the allowance for credit losses is determined by discounting the expected future cash flows at the original interest rate of the loan.

The CARES Act provided guidance around the modification of loans as a result of the COVID-19 pandemic, which outlined, among other criteria, that short-term modifications made on a good faith basis to borrowers who were current as defined under the CARES Act prior to any relief, are not TDRs. This includes short-term (e.g. six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. To qualify as an eligible loan under the CARES Act, a loan modification must be (1) related to COVID-19; (2) executed on a loan that was not more than 30 days past due as of December 31, 2019; and (3) executed between March 1, 2020, and the earlier of (a) 60 days after the date of termination of the national emergency by the President or (b) December 31, 2020.

Loan Origination and Commitment Fees:  Loan origination fees, net of certain specifically defined direct loan origination costs, are deferred and recognized as an adjustment of the loans’ interest yield using the level-yield method over the contractual term of each loan adjusted for actual loan prepayment experience.  Net deferred fees or costs related to loans held for sale are recognized as part of the cost basis of the loan.  Loan commitment fees are deferred until the expiration of the commitment period unless management believes there is a remote likelihood that the underlying commitment will be exercised, in which case the fees are amortized to fee income using the straight-line method over the commitment period.  If a loan commitment is exercised, the deferred commitment fee is accounted for in the same manner as a loan origination fee.  Deferred commitment fees associated with expired commitments are recognized as fee income.

Allowance for Credit Losses - unfunded loan commitments: An allowance for credit losses - unfunded loan commitments is maintained at a level that, in the opinion of management, is adequate to absorb expected credit losses associated with the contractual life of the Banks’ commitments to lend funds under existing agreements such as letters or lines of credit. The Banks use a methodology for determining the allowance for credit losses - unfunded loan commitments that applies the same segmentation and loss rate to each pool as the funded exposure adjusted for probability of funding. Draws on unfunded loan commitments that are considered uncollectible at the time funds are advanced are charged to the allowance for credit losses on off-balance sheet exposures. Provisions for credit losses - unfunded loan commitments are recognized in non-interest expense and added to the allowance for credit losses - unfunded loan commitments, which is included in other liabilities in the consolidated statements of financial condition.
