the requisite regulatory approvals for the AmericanWest transaction might not be obtained; the credit risks of lending activities, including changes in the level and trend of loan delinquencies and write-offs and changes in our allowance for loan losses and provision for loan losses that may be impacted by deterioration in the housing and commercial real estate markets and may lead to increased losses and non-performing assets, and may result in our allowance for loan losses not being adequate to cover actual losses and require us to materially increase our reserves; changes in economic conditions in general and Washington, Idaho, Oregon, Utah and California in particular; changes in the levels of general interest rates and the relative differences between short and long-term interest rates, loan and deposit interest rates, our net interest margin and funding sources; fluctuations in the demand for loans, the number of unsold homes, land and other properties and fluctuations in real estate values in our market areas; secondary market conditions for loans and our ability to sell loans in the secondary market; results of examinations of us by the Board of Governors of the Federal Reserve System (the Federal Reserve Board) and of our bank subsidiaries by the Federal Deposit Insurance Corporation (the FDIC), the Washington State Department of Financial Institutions, Division of Banks (the Washington DFI) or other regulatory authorities, including the possibility that any such regulatory authority may, among other things, institute an informal or formal enforcement action against us or any of our bank subsidiaries which could require us to increase our reserve for loan losses, write-down assets, change our regulatory capital position or affect our ability to borrow funds, or maintain or increase deposits, or impose additional requirements and restrictions on us, any of which could adversely affect our liquidity and earnings; legislative or regulatory changes that adversely affect our business including changes in regulatory policies and principles, or the interpretation of regulatory capital or other rules, including changes related to Basel III; the impact of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the implementing regulations; our ability to attract and retain deposits; increases in premiums for deposit insurance; our ability to control operating costs and expenses; the use of estimates in determining fair value of certain of our assets and liabilities, which estimates may prove to be incorrect and result in significant changes in valuation; difficulties in reducing risk associated with the loans on our balance sheet; staffing fluctuations in response to product demand or the implementation of corporate strategies that affect our work force and potential associated charges; the failure or security breach of computer systems on which we depend; our ability to retain key members of our senior management team; costs and effects of litigation, including settlements and judgments; our ability to implement our business strategies; future goodwill impairment due to changes in our business, changes in market conditions, or other factors; our ability to manage loan delinquency rates; increased competitive pressures among financial services companies; changes in consumer spending, borrowing and savings habits; the availability of resources to address changes in laws, rules, or regulations or to respond to regulatory actions; our ability to pay dividends on our common stock and interest or principal payments on our junior subordinated debentures; adverse changes in the securities markets; inability of key third-party providers to perform their obligations to us; changes in accounting policies and practices, as may be adopted by the financial institution regulatory agencies or the Financial Accounting Standards Board including additional guidance and interpretation on accounting issues and details of the implementation of new accounting methods; the economic impact of war or any terrorist activities; other economic, competitive, governmental, regulatory, and technological factors affecting our operations, pricing, products and services; and other risks detailed from time to time in our filings with the Securities and Exchange Commission.  Any forward-looking statements are based upon management’s beliefs and assumptions at the time they are made.  We do not undertake and specifically disclaim any obligation to update any forward-looking statements included in this report or the reasons why actual results could differ from those contained in such statements whether as a result of new information, future events or otherwise.  These risks could cause our actual results to differ materially from those expressed in any forward-looking statements by, or on behalf of, us.  In light of these risks, uncertainties and assumptions, the forward-looking statements discussed in this report might not occur, and you should not put undue reliance on any forward-looking statements.

SELECTED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Note 1:  BASIS OF PRESENTATION AND CRITICAL ACCOUNTING POLICIES

The accompanying unaudited consolidated interim 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 consolidated interim 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 condensed consolidated financial statements, the Company has evaluated events and transactions subsequent to March 31, 2015 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 disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. Certain reclassifications have been made to the 2014 Consolidated Financial Statements and/or schedules to conform to the 2015 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 critical 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 loan and lease losses, (iii) the valuation of financial assets and liabilities recorded at fair value, including other-than-temporary impairment (OTTI) losses, (iv) the valuation of intangibles, such as goodwill, core deposit intangibles and mortgage servicing rights, (v) the valuation of or recognition of deferred tax assets and liabilities, and (vi) the application of acquisition accounting standards to business combinations including purchased credit-impaired loans. 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, 2014 filed with the SEC.  There have been no significant changes in our application of accounting policies during the first three months of 2015.

The information included in this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2014 as filed with the SEC (2014 Form 10-K).  Interim results are not necessarily indicative of results for a full year or any other interim period.

Note 2:  RECENT DEVELOPMENTS AND SIGNIFICANT EVENTS

Proposed Acquisition of AmericanWest Bank

On November 5, 2014, we announced the execution of a definitive agreement to purchase Starbuck Bancshares, Inc. (Starbuck) the bank holding company of AmericanWest Bank (AmericanWest), a Washington state chartered commercial bank headquartered in Spokane, Washington, with 94 branches serving markets in Washington, Oregon, Idaho, California and Utah. The merger agreement provides that Starbuck will merge with and into a wholly-owned subsidiary of the Company. Immediately following the merger, Starbuck's wholly owned bank subsidiary, AmericanWest will merge with Banner Bank. At March 31, 2015, Starbuck had $4.6 billion in assets, $3.0 billion in net loans, $3.7 billion in deposits and equity of $586 million, including AmericanWest's recent acquisition of Greater Sacramento Bancorp which was completed on February 6, 2015. The merged banks will operate under the Banner Bank brand. Under the terms of the agreement, the aggregate consideration to be received by Starbuck equity holders will consist of a fixed amount of 13.23 million shares of Banner common stock and $130.0 million in cash. Upon completion of the transaction, such shares will represent an approximately 38.8% pro forma ownership interest in Banner. The merger is expected to close early in the third quarter of 2015 and is subject to approval by regulatory agencies as well as other customary closing conditions. Upon completion of the AmericanWest merger, Banner Bank will have more than 190 locations in five western states, a significantly expanded customer base and meaningfully increased business opportunities.

Acquisition of Siuslaw Financial Group, Inc.

As of the close of business on March 6, 2015, the Company completed its acquisition of Siuslaw Financial Group (Siuslaw) and its subsidiary, Siuslaw Bank, an Oregon state chartered commercial bank with ten branches in Lane County, Oregon, including Eugene, Oregon. On that date Siuslaw was merged into Banner Corporation and Siuslaw Bank was merged into Banner Bank. The operating results produced by the ten branches acquired in the Siuslaw acquisition are included in Banner Bank's financial results beginning March 7, 2015 and the combined banks are operating under the Banner Bank name and brand. (See Note 4, Business Combinations, below in this Form 10-Q for additional information regarding the acquisition).

Note 3:  ACCOUNTING STANDARDS RECENTLY ISSUED OR ADOPTED

Investing in Qualified Affordable Housing Projects

10

In January 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. The objective of this ASU is to provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit. The amendments in this ASU modify the conditions that a reporting entity must meet to be eligible to use a method other than the equity or cost methods to account for qualified affordable housing project investments. If the modified conditions are met, the amendments permit an entity to amortize the initial cost of the investment in proportion to the amount of tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense (benefit). Additionally, the amendments introduce new recurring disclosures about all investments in qualified affordable housing projects irrespective of the method used to account for the investments. The amendments in this ASU have been applied retrospectively to all periods presented. ASU No. 2014-01 is effective beginning after December 15, 2014 and did not have a material impact on the Company's consolidated financial statements.

Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure

In January 2014, FASB issued ASU No. 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The amendments in this ASU clarify that an in-substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU No. 2014-04 is effective for fiscal years and interim periods beginning after December 15, 2014 and did not have a material impact on the Company's consolidated financial statements.

Revenue from Contracts with Customers

In May 2014, FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which creates Topic 606 and supersedes Topic 605, Revenue Recognition. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The standard is effective for public entities for interim and annual periods beginning after December 15, 2016 although FASB issued a proposed ASU on April 29, 2015 that would defer the effective date by one year (i.e. to reporting periods beginning after December 15, 2017); early adoption is not permitted. For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company is currently evaluating the provisions of ASU No. 2014-09 to determine the potential impact the standard will have on the Company’s consolidated financial statements.

Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure

In August 2014, FASB issued ASU No. 2014-14, Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure. The amendments in this ASU affect creditors that hold government-guaranteed mortgage loans, including those guaranteed by the FHA and the VA. The ASU provides specific guidance on how to classify or measure foreclosed mortgage loans that are government guaranteed. The amendments in this Update require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: 1) the loan has a government guarantee that is not separable from the loan before foreclosure, 2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and creditor has the ability to recover under the claim and, 3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. ASU No. 2014-14 is effective for fiscal years and interim periods beginning after December 15, 2014 and did not have a material impact on the Company's consolidated financial statements.

Income Statement - Extraordinary and Unusual Items (Subtopic 225-20)

In January 2015, FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20). The ASU eliminated from GAAP the concept of extraordinary items. Under subtopic 225-20, entities were required to separately classify, present, and disclose extraordinary events and transactions that were both unusual in nature and infrequent in occurrence. This amendment will save time and reduce costs for preparers, as well as alleviate uncertainty for auditors and regulators in evaluating potentially extraordinary items. The amendment is effective for fiscal years and interim reporting periods after December 15, 2015. It may be applied prospectively, and retrospectively to all reporting periods presented in the financial statements. The adoption of ASU No. 2015-01 did not have a material impact on the Company's consolidated financial statements.

Acquisition of Siuslaw Financial Group, Inc.

Effective as of the close of business on March 6, 2015, the Company completed the purchase of Siuslaw, the holding company of Siuslaw Bank. Siuslaw merged with and into the Company and, immediately following, Siuslaw Bank merged with and into Banner Bank. Siuslaw shareholders received 0.32231 shares of the Company's common stock and $1.41622 in cash in exchange for each share of Siuslaw common stock. The Company acquired 100% of Siuslaw's voting equity interests in the transaction. The acquisition provided $370 million in assets, $316 million in deposits and $247 million in loans.

The assets acquired and liabilities assumed in the purchase have been accounted for under the acquisition method of accounting and, accordingly, the assets and liabilities, both tangible and intangible, were recorded at their estimated fair value as of the acquisition date. The application of the acquisition method of accounting resulted in recognition of a core deposit intangible asset of $3.9 million and goodwill of $21.1 million. The acquired core deposit intangible has been determined to have a useful life of approximately eight years and will be amortized on an accelerated basis. Goodwill is not amortized but will be evaluated for impairment on an annual basis or more often if circumstances dictate to determine if the carrying value remains appropriate. Goodwill will not be deductible for income tax purposes as the acquisition is accounted for as a tax-free exchange for tax purposes.

The following table presents a summary of the consideration paid and the estimated fair values as of the acquisition date for each major class of assets acquired and liabilities assumed (in thousands):

	Siuslaw
	March 6, 2015
Consideration to Siuslaw shareholders:
Cash paid			$	5,806
Fair value of common shares issued			58,100
Total consideration			63,906
Fair value of assets acquired:
Cash and cash equivalents	$	84,405
Securities—available-for-sale	12,865
Loans receivable (contractual amount of $252.2 million)	247,098
Real estate owned, held for sale	2,525
Property and equipment	8,127
Core deposit intangible	3,895
Other assets	11,391
Total assets acquired	370,306
Fair value of liabilities assumed:
Deposits	316,406
Junior subordinated debentures	5,959
Other liabilities	5,183
Total liabilities assumed	327,548
Net assets acquired			42,758
Goodwill			$	21,148

Acquired goodwill represents the premium the Company paid over the fair value of the net tangible and intangible assets acquired. The Company paid this premium for a number of reasons, including growing the Company's customer base, acquiring assembled workforces, and expanding its presence in new markets. See Note 9, Goodwill and Other Intangible Assets for the accounting for goodwill and other intangible assets.

Amounts recorded are preliminary estimates of fair value. Additional adjustments to the purchase price allocation may be required and would most likely involve loans or property and equipment. The primary reason for the acquisition was to continue the Company's growth strategy, including expanding our geographic footprint in markets throughout the Northwest. As of March 6, 2015, the unpaid principal balance on purchased non-credit-impaired loans was $244.2 million. The fair value of the purchased non-credit-impaired loans was $241.4 million, resulting in a discount of $2.8 million recorded on these loans.

The following table presents the acquired purchased credit-impaired loans as of the acquisition date (in thousands):

	Siuslaw
	March 6, 2015
Acquired purchased credit-impaired loans:
Contractually required principal and interest payments	$	11,134
Nonaccretable difference	(3,238		)
Cash flows expected to be collected	7,896
Accretable yield	(2,239		)
Fair value of purchased credit-impaired loans	$	5,657

The following table presents certain unaudited pro forma information for illustrative purposes only, for the three months ended March 31, 2015 and 2014 as if Siuslaw had been acquired on January 1, 2014. This unaudited estimated pro forma financial information combines the historical results of Siuslaw with the Company’s consolidated historical results. The pro forma information is not indicative of what would have occurred had the acquisition occurred on January 1, 2014. In particular, no adjustments have been made to eliminate the impact of other-than-temporary impairment losses and losses recognized on the sale of securities that may not have been necessary had the investment securities been recorded at fair value as of January 1, 2014. The unaudited pro forma information does not consider any changes to the provision for credit losses resulting from recording loan assets at fair value. Additionally, Banner expects to achieve further operating cost savings and other business synergies, including revenue growth, as a result of the acquisition which are not reflected in the pro forma amounts that follow. As a result, actual amounts would have differed from the unaudited pro forma information presented. (in thousands except per share).

	Pro Forma
	Three Months Ended March 31,
	2015		2014
Total revenues (net interest income plus non-interest income	$	63,164	$	55,829
Net income	$	12,518	$	11,413
Earnings per share - basic	$	0.59	$	0.55
Earnings per share - diluted	$	0.59	$	0.55

The operating results of the Company include the operating results produced by the acquired assets and assumed liabilities of Siuslaw for the period March 7, 2015 to March 31, 2015. Disclosure of the amount of Siuslaw’s revenue and net income (excluding integration costs) included in the Company’s consolidated income statement is impracticable due to the integration of the operations and accounting for this acquisition.

Acquisition of Six Oregon Branches

Effective as of the close of business on June 20, 2014, Banner Bank completed the purchase of six branches from Umpqua Bank, successor to Sterling Savings Bank (the Branch Acquisition). Five of the six branches are located in Coos County, Oregon and the sixth branch is located in Douglas County, Oregon. The purchase provided $212 million in deposit accounts, $88 million in loans, and $3 million in branch properties. Banner Bank received $128 million in cash from the transaction.

The assets acquired and liabilities assumed in the purchase have been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the acquisition date. The application of the acquisition method of accounting resulted in recognition of a core deposit intangible asset of $2.4 million and an acquisition bargain purchase gain of $9.1 million. The bargain purchase gain represents the excess fair value of the net assets acquired over the purchase price, including fair value of liabilities assumed. The bargain purchase gain consisted primarily of a $7.0 million discount on the assets acquired in this required branch divestiture combined with a $2.4 million core deposit intangible, net of approximately $300,000 in other fair value adjustments. The acquired core deposit intangible was determined to have a useful life of approximately eight years and is being amortized on an accelerated basis.

13

The following table displays the fair value as of the acquisition date for each major class of assets acquired and liabilities assumed (in thousands):

	Branch Acquisition
	June 20, 2014
Total consideration			$	—
Fair value of assets acquired:
Cash and cash equivalents	$	127,557

Deposits	212,085
Other liabilities	42
Total liabilities assumed	212,127
Net assets acquired			$	9,079
Acquisition bargain purchase gain			$	(9,079	)

The primary reason for the acquisition was to continue the Company's growth strategy, including expanding its geographic footprint in markets throughout the Northwest. As of June 20, 2014, the transaction had no remaining contingencies. The operating results of the Company include the operating results produced by the Branch Acquisition from June 21, 2014 to March 31, 2015. Pro forma results of operations for the three months ended March 31, 2015 and 2014, as if the Branch Acquisition had occurred on January 1, 2014, have not been presented because historical financial information was not available. There were not any purchased credit-impaired loans acquired in connection with the Branch Acquisition.

There were six sales of securities—available-for-sale totaling $28.2 million with a resulting net gain of $34,000 during the three months ended March 31, 2014.  At March 31, 2015, there were 59 securities—available for sale with unrealized losses, compared to 94 securities at December 31, 2014.  Management does not believe that any individual unrealized loss as of March 31, 2015 represents OTTI.  The decline in fair market values of these securities was generally due to changes in interest rates and changes in market-desired spreads subsequent to their purchase. There were no securities—available-for-sale on nonaccrual status at March 31, 2015 or 2014.

Note 6:  FHLB STOCK

The Banks’ investments in Federal Home Loan Bank of Seattle stock are carried at cost, which is its par value ($100 per share) and which reasonably approximates its fair value.  As members of the FHLB system, the Banks are required to maintain a minimum level of investment in FHLB stock based on specific percentages of their outstanding FHLB advances.  At March 31, 2015 and December 31, 2014, respectively, the Company had recorded $25.5 million and $27.0 million in investments in FHLB stock.  This stock is generally viewed as a long-term investment and it does not have a readily determinable fair value.  Ownership of FHLB stock is restricted to the FHLB and member institutions and can only be purchased and redeemed at par. For the three months ended March 31, 2015 and 2014, the Banks received dividend income of $7,000 and $9,000, respectively, on FHLB stock.

Management periodically evaluates FHLB stock for impairment.  Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value.  The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB.

The FHLB repurchased $2.0 million of the Banks' stock during the quarter ending March 31, 2015. On September 25, 2014, the FHLB of Seattle entered into an Agreement and Plan of Merger with and into the FHLB of Des Moines. The merger was approved by the members of both the Seattle and Des Moines Federal Home Loan Banks on February 27, 2015 and the merger is expected to be completed by mid-year 2015. Based on the above, the Company has determined there was no impairment on its FHLB stock investment as of March 31, 2015.

Note 7: LOANS RECEIVABLE AND THE ALLOWANCE FOR LOAN LOSSES

The Banks originate residential mortgage loans for both portfolio investment and sale in the secondary market. At the time of origination, mortgage loans are designated as held for sale or held for investment. Loans held for sale are stated at the lower of cost or estimated market value determined on an aggregate basis. Net unrealized losses on loans held for sale are recognized through a valuation allowance by charges to income. The Banks also originate construction, land and land development, commercial and multifamily real estate, commercial business, agricultural business and consumer loans for portfolio investment. Loans receivable not designated as held for sale are recorded at the principal amount outstanding, net of deferred fees and origination costs, and discounts and premiums.  Loans acquired in business combinations are recorded at their fair value at the date of acquisition. Premiums, discounts and deferred loan fees and origination costs are amortized to maturity using the level-yield methodology.

Interest is accrued as earned unless management doubts the collectability of the loan or the unpaid interest. Interest accruals are generally discontinued when loans become 90 days past due for scheduled interest payments. All previously accrued but uncollected interest is deducted from interest income upon transfer to nonaccrual status. Future collection of interest is included in interest income based upon an assessment of the likelihood that the loans 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 loan may be uncollectable. Such interest is then recognized as income only if it is ultimately collected.

Total adjustable-rate loans	2,721,056		2,539,558
Total loans	$	4,114,818	$	3,833,820

The adjustable-rate loans have interest rate adjustment limitations and are generally indexed to various prime or London Inter-bank Offering Rate (LIBOR) rates, One to Five Year Constant Maturity Treasury Indices or FHLB advance rates.  Future market factors may affect the correlation of the interest rate adjustment with the rates the Banks pay on the short-term deposits that were primarily utilized to fund these loans.

Impaired Loans and the Allowance for Loan Losses.  A loan is considered impaired when, based on current information and circumstances, the Company determines it is probable that it will be unable to collect all amounts due according to the contractual terms of the loan agreement, including scheduled interest payments.  Impaired loans are comprised of loans on nonaccrual, troubled debt restructurings (TDRs) that are performing under their restructured terms, and loans that are 90 days or more past due, but are still on accrual.

Troubled Debt Restructures. Some of the Company’s loans are reported as TDRs.  Loans are reported as TDRs when the bank grants one or more concessions 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.  Our TDRs have generally not involved forgiveness of amounts due, but almost always include a modification of multiple factors; the most common combination includes interest rate, payment amount and maturity date. As a result of these concessions, restructured loans are impaired as the Company will not collect all amounts due, both principal and interest, in accordance with the terms of the original loan agreement.  Loans identified as TDRs are accounted for in accordance with the Company's impaired loan accounting policies.

23

Purchased loans, including loans acquired in business combinations, are recorded at their fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either purchased credit-impaired or purchased non-credit-impaired. Purchased credit-impaired loans reflect credit deterioration since origination such that it is probable at acquisition that the Company will be unable to collect all contractually required payments. The outstanding contractual unpaid principal balance of purchased credit-impaired loans, excluding acquisition accounting adjustments, was $9.1 million at March 31, 2015. The carrying balance of purchased credit-impaired loans was $5.7 million at March 31, 2015. There were no purchased credit-impaired loans at December 31, 2014 or March 31, 2014.

The following table presents the changes in the accretable yield for purchased credit-impaired loans for the three months ended March 31, 2015 and 2014 (in thousands):

⁽¹⁾  Loans without a specific allowance reserve have not been individually evaluated for impairment, but have been included in pools of homogeneous loans for evaluation of related allowance reserves.

⁽²⁾  Loans with a specific allowance reserve have been individually evaluated for impairment using either a discounted cash flow analysis or, for collateral dependent loans, current appraisals less costs to sell to establish realizable value.  These analyses may identify a specific impairment amount needed or may conclude that no reserve is needed.  Any specific impairment that is identified is included in the category’s Related Allowance column.

⁽¹⁾  Since these loans were already considered classified and/or on nonaccrual status prior to restructuring, the modifications did not have a material effect on the Company’s determination of the allowance for loan losses.

⁽²⁾  The majority of these modifications do not fit into one separate type, such as rate, term, amount, interest-only or payment, but instead are a combination of multiple types of modifications; therefore, they are disclosed in aggregate.

There were no TDRs which incurred a payment default within twelve months of the restructure date during the three-month periods ended March 31, 2015 and 2014.  A default on a TDR results in either a transfer to nonaccrual status or a partial charge-off.

Credit Quality Indicators:  To appropriately and effectively manage the ongoing credit quality of the Company’s loan portfolio, management has implemented a risk-rating or loan grading system for its loans.  The system is a tool to evaluate portfolio asset quality throughout each applicable loan’s life as an asset of the Company.  Generally, loans and leases are risk rated on an aggregate borrower/relationship basis with individual loans sharing similar ratings.  There are some instances when specific situations relating to individual loans will provide the basis for different risk ratings within the aggregate relationship.  Loans are graded on a scale of 1 to 9.  A description of the general characteristics of these categories is shown below:

Overall Risk Rating Definitions:  Risk-ratings contain both qualitative and quantitative measurements and take into account the financial strength of a borrower and the structure of the loan or lease.  Consequently, the definitions are to be applied in the context of each lending transaction and judgment must also be used to determine the appropriate risk rating, as it is not unusual for a loan or lease to exhibit characteristics of more than one risk-rating category.  Consideration for the final rating is centered in the borrower’s ability to repay, in a timely fashion, both principal and interest.  There were no material changes in the risk-rating or loan grading system in the three months ended March 31, 2015.

Risk Rating 1: Exceptional

A credit supported by exceptional financial strength, stability, and liquidity.  The risk rating of 1 is reserved for the Company’s top quality loans, generally reserved for investment grade credits underwritten to the standards of institutional credit providers.

Risk Rating 2: Excellent

A credit supported by excellent financial strength, stability and liquidity.  The risk rating of 2 is reserved for very strong and highly stable customers with ready access to alternative financing sources.

Risk Rating 3: Strong

A credit supported by good overall financial strength and stability.  Collateral margins are strong; cash flow is stable although susceptible to cyclical market changes.

Risk Rating 4: Acceptable

A credit supported by the borrower’s adequate financial strength and stability.  Assets and cash flow are reasonably sound and provide for orderly debt reduction.  Access to alternative financing sources will be more difficult to obtain.

Risk Rating 5: Watch

A credit with the characteristics of an acceptable credit which requires, however, more than the normal level of supervision and warrants formal quarterly management reporting.  Credits in this category are not yet criticized or classified, but due to adverse events or aspects of underwriting require closer than normal supervision. Generally, credits should be watch credits in most cases for six months or less as the impact of stress factors are analyzed.

Risk Rating 6: Special Mention

A credit with potential weaknesses that deserves management’s close attention is risk rated a 6.  If left uncorrected, these potential weaknesses will result in deterioration in the capacity to repay debt.  A key distinction between Special Mention and Substandard is that in a Special Mention credit, there are identified weaknesses that pose potential risk(s) to the repayment sources, versus well defined weaknesses that pose risk(s) to the repayment sources.  Assets in this category are expected to be in this category no more than 9-12 months as the potential weaknesses in the credit are resolved.

Risk Rating 7: Substandard

A credit with well defined weaknesses that jeopardize the ability to repay in full is risk rated a 7.  These credits are inadequately protected by either the sound net worth and payment capacity of the borrower or the value of pledged collateral.  These are credits with a distinct possibility of loss.  Loans headed for foreclosure and/or legal action due to deterioration are rated 7 or worse.

Risk Rating 8: Doubtful

A credit with an extremely high probability of loss is risk rated 8.  These credits have all the same critical weaknesses that are found in a substandard loan; however, the weaknesses are elevated to the point that based upon current information, collection or liquidation in full is improbable.  While some loss on doubtful credits is expected, pending events may strengthen a credit making the amount and timing of any loss indeterminable.  In these situations taking the loss is inappropriate until it is clear that the pending event has failed to strengthen the credit and improve the capacity to repay debt.

Risk Rating 9: Loss

A credit that is considered to be currently uncollectible or of such little value that it is no longer a viable Bank asset is risk rated 9.  Losses should be taken in the accounting period in which the credit is determined to be uncollectible.  Taking a loss does not mean that a credit has absolutely no recovery or salvage value but, rather, it is not practical or desirable to defer writing off the credit, even though partial recovery may occur in the future.

Note 9:  GOODWILL, OTHER INTANGIBLE ASSETS AND MORTGAGE SERVICING RIGHTS

Goodwill and Other Intangible Assets:  At March 31, 2015, intangible assets are comprised of goodwill and core deposit intangibles (CDI) acquired in business combinations. Goodwill represents the excess of the total purchase price paid over the fair value of the assets acquired, net of the fair values of liabilities assumed, and is not amortized but is reviewed annually for impairment. Additions to goodwill during 2015 relate to the Siuslaw acquisition. See Note 4, Business Combinations, for additional information on the acquisition and purchase price allocation.

The Company amortizes CDI over their estimated useful lives and reviews them at least annually for events or circumstances that could impair their value.  The CDI assets shown in the table below represent the value ascribed to the long-term deposit relationships acquired in three separate bank acquisitions during 2007, a single branch acquisition in 2013, the Branch Acquisition in 2014 and the acquisition of Siuslaw in 2015.  These intangible assets are being amortized using an accelerated method over estimated useful lives of three to eight years.  The CDI assets are not estimated to have a significant residual value.

The following table summarizes the changes in the Company’s goodwill and other intangibles for the three months ended March 31, 2015 and the year ended December 31, 2014 (in thousands):

	Goodwill		CDI			Total

Mortgage Servicing Rights:  Mortgage servicing rights are reported in other assets. Mortgage servicing rights are initially recorded at fair value and are amortized in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets.  Mortgage servicing rights are subsequently evaluated for impairment based upon the fair value of the rights compared to the amortized cost (remaining unamortized initial fair value).  If the fair value is less than the amortized cost, a valuation allowance is created through an impairment charge, which is recognized in servicing fee income on the consolidated statement of operations.   However, if the fair value is greater than the amortized cost, the amount above the amortized cost is not recognized in the carrying value.  Loans serviced for others totaled $2.096 billion and $1.391 billion at March 31, 2015 and December 31, 2014, respectively.  Custodial accounts maintained in connection with this servicing totaled $8.0 million and $6.7 million at March 31, 2015 and December 31, 2014, respectively.

An analysis of our mortgage servicing rights, net of valuation allowances, for the three months ended March 31, 2015 and 2014 is presented below (in thousands):

	Three Months Ended March 31
	2015			2014

Amortization (1)	(709		)	(462		)
Balance, end of the period (2)	$	11,709		$	8,199

⁽¹⁾  Amortization of mortgage servicing rights is recorded as a reduction of loan servicing income and any unamortized balance is fully written off if the loan repays in full.

⁽²⁾  There was no valuation allowance as of March 31, 2015 and 2014.

Note 11:  FAIR VALUE ACCOUNTING AND MEASUREMENT

The Company measures and discloses certain assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (that is, not a forced liquidation or distressed sale). GAAP (ASC 820, Fair Value Measurements) establishes a consistent framework for measuring fair value and disclosure requirements about fair value measurements. Among other things, the accounting standard requires the reporting entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s estimates for market assumptions. These two types of inputs create the following fair value hierarchy:

• Level 1 – Quoted prices in active markets for identical instruments. An active market is a market in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available.

• Level 2 – Observable inputs other than Level 1 including quoted prices in active markets for similar instruments, quoted prices in less active markets for identical or similar instruments, or other observable inputs that can be corroborated by observable market data.

• Level 3 – Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation; also includes observable inputs from non-binding single dealer quotes not corroborated by observable market data.

The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize at a future date. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for certain financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values. Transfers between levels of the fair value hierarchy are deemed to occur at the end of the reporting period.

Items Measured at Fair Value on a Recurring Basis:

Banner records trading account securities, securities available-for-sale, FHLB advances, junior subordinated debentures and certain derivative transactions at fair value on a recurring basis.

• Investment securities primarily consist of U.S. Government and agency obligations, municipal bonds, corporate bonds, single issue trust preferred securities (TPS), pooled trust preferred collateralized debt obligation securities (TRUP CDO), mortgage-backed securities, asset-backed securities, equity securities and certain other financial instruments.

From mid-2008 through the current quarter, the lack of active markets and market participants for certain securities resulted in an increase in Level 3 measurements. In particular, the market for our TRUP CDO securities has been generally inactive during this period. This was evidenced first by a significant widening of the bid-ask spread in the brokered markets in which TRUP CDOs trade and then by a significant decrease in the volume of trades relative to historical levels. The new issue market also has been inactive as almost no new TRUP CDOs have been issued since 2007. There are still very few market participants who are willing and/or able to transact for these securities. Thus, a low market price for a particular bond may only provide evidence of stress in the credit markets in general rather than being an indicator of credit problems with a particular issuer or of the fair value of the security. As of March 31, 2015, Banner owned $6 million in par value of these securities.

Given these conditions in the debt markets and the absence of observable transactions in the secondary and new issue markets, management determined that for the TRUP CDOs at March 31, 2015 and December 31, 2014:

• The few observable transactions and market quotations that were available were not reliable for purposes of determining fair value,

• An income valuation approach technique (present value technique) that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs was equally or more representative of fair value than the market approach valuation technique, and

• The Company’s TRUP CDOs should be classified exclusively within Level 3 of the fair value hierarchy because of the significant assumptions required to determine fair value at the measurement date.

39

The TRUP CDO valuations were derived using input from independent third parties who used proprietary cash flow models for analyzing collateralized debt obligations. Their approaches to determining fair value involve considering the credit quality of the collateral, assuming a level of defaults based on the probability of default of each underlying trust preferred security, creating expected cash flows for each TRUP CDO security and discounting that cash flow at an appropriate risk-adjusted rate plus a liquidity premium.

Where appropriate, management reviewed the valuation methodologies and assumptions used by the independent third party providers and determined that the fair value estimates were reasonable and utilized those estimates in the Company’s reported financial statements. One TRUP CDO security was sold in the first quarter 2015 at a price significantly less than par, but more than our carrying value. For that security we received $2.2 million against an unamortized cost of $2.9 million and a carrying value of $1.7 million. A book loss was recognized in the amount of $642,000 but an offsetting reversal of a fair value allowance was also recorded as a gain of $1.2 million, resulting in a net gain for this security of $555,000 in the current quarter. Another TRUP CDO security was partially redeemed in the amount of $109,000 against a carrying value of zero, resulting in a reversal of a valuation allowance of $109,000. The aggregate result of the fair value analysis of all the Level 3 TRUP CDO measurements was a fair value gain of $1.4 million in the quarter ended March 31, 2015.

At March 31, 2015, Banner also owned approximately $19 million in amortized cost of single issuer TPS securities for which no direct market data or independent valuation source is available. Similar to the TRUP CDOs above, there were too few, if any, issuances of new TPS securities or sales of existing TPS securities to provide Level 1 or even Level 2 fair value measurements for these securities. Management, therefore, utilized a discounted cash-flow model to calculate the present value of each security’s expected future cash flows to determine their respective fair values. Management took into consideration the limited market data that was available regarding similar securities and assessed the performance of the three individual issuers of TPS securities owned by the Company. In the current quarter, the Company again sought input from independent third parties to help it establish an appropriate set of parameters to identify a reasonable range of discount rates for use in its fair value model. Management concluded that market yields have been relatively stable in the quarter ended March 31, 2015 and that the indicated spreads and implied yields for non-investment grade securities as well as the yields associated with individual issuers in the third party analyst reports continue to support that a 500 basis point spread over the three-month LIBOR index, the same spread as used in the quarter ended December 31, 2014, was still a reasonable basis for determining an appropriate discount rate to estimate the fair value of these securities. These factors were then incorporated into the model at March 31, 2015, where a discount rate equal to three-month LIBOR plus 500 basis points was used to calculate the respective fair values of these securities. The result of this Level 3 fair value measurement was a fair value gain of $43,000 in the quarter ended March 31, 2015. The Company has and will continue to assess the appropriate fair value hierarchy for determination of fair values on TRUP CDO and TPS securities on a quarterly basis. For all other trading securities and securities available-for-sale we used matrix pricing models from investment reporting and valuation services. Management considers this to be a Level 2 input method.

• Fair valuations for FHLB advances are estimated using fair market values provided by the lender, the FHLB of Seattle. The FHLB of Seattle prices advances by discounting the future contractual cash flows for individual advances using its current cost of funds curve to provide the discount rate. Management considers this to be a Level 2 input method.

• The fair valuations of junior subordinated debentures (TPS-related debt that the Company has issued or acquired in the Siuslaw merger) were also valued using discounted cash flows. These debentures carry interest rates that reset quarterly, using the three-month LIBOR index plus spreads of 1.38% to 3.35%.  While the quarterly reset of the index on this debt would seemingly keep its fair value reasonably close to book value, the disparity in the fixed spreads above the index and the inability to determine realistic current market spreads, due to lack of new issuances and trades, resulted in having to rely more heavily on assumptions about what spread would be appropriate if market transactions were to take place. In periods prior to the third quarter of 2008, the discount rate used was based on recent issuances or quotes from brokers on the date of valuation for comparable bank holding companies and was considered to be a Level 2 input method. However, as noted above in the discussions of TPS and TRUP CDOs, due to the unprecedented disruption of certain financial markets, management concluded that there were insufficient transactions or other indicators to continue to reflect these measurements as Level 2 inputs.  Due to this reliance on assumptions and not on directly observable transactions, management believes fair value for these instruments should follow a Level 3 input methodology. Since the discount rate used in the fair value modeling is the most sensitive unobservable estimate in the calculation, the Company again utilized input from the same independent third party noted above to help it establish an appropriate set of parameters to identify a reasonable range of discount rates for use in its fair value model. In valuing the debentures at March 31, 2015, management evaluated the general market for credit spreads as noted above and for the discount rate used the period-ending three-month LIBOR plus 500 basis points. As noted above in the discussion about single-issuer TPS securities, since market spreads have been relatively stable in the recent period we used the same spread as used in the quarter ended December 31, 2014, resulting in a fair value loss on these instruments of $366,000 for the quarter ended March 31, 2015. The fair value adjustment in the current period was attributed to the passage of time on the years to maturity in the discounted present value calculation used to estimate the fair value.

• Derivative instruments include interest rate commitments related to one- to four-family loans and residential mortgage-backed securities and interest rate swaps.  The fair value of interest rate lock commitments and forward sales commitments are estimated using quoted or published market prices for similar instruments, adjusted for factors such as pull-through rate assumptions based on historical trends, where appropriate.  The fair value of interest rate swaps is determined by using current market quotes on similar instruments provided by active broker/dealers in the swap market.  Management considers these to be Level 2 input methods. The changes in the fair value of all of these derivative instruments are primarily attributable to changes in the level of market interest rates.  The Company has elected to record the fair value of these derivative instruments on a net basis.

The Company has elected to continue to recognize the interest income and dividends from the securities reclassified to fair value as a component of interest income as was done in prior years when they were classified as available-for-sale.  Interest expense related to the FHLB advances and junior subordinated debentures continues to be measured based on contractual interest rates and reported in interest expense.  The change in fair market value of these financial instruments has been recorded as a component of other operating income.

Items Measured at Fair Value on a Non-recurring Basis:

Impaired loans are periodically evaluated to determine if valuation adjustments, or partial write-downs, should be recorded. The need for valuation adjustments arises when observable market prices or current appraised values of collateral indicate a shortfall in collateral value or discounted cash flows indicate a shortfall compared to current carrying values of the related loan. If the Company determines that the value of the impaired loan is less than the carrying value of the loan, the Company either establishes an impairment reserve as a specific component of the allowance for loan and lease losses (ALLL) or charges off the impaired amount. These valuation adjustments are considered non-recurring fair value adjustments. The remaining impaired loans are evaluated for reserve needs in homogenous pools within the Company’s ALLL methodology. As of March 31, 2015, the Company reviewed all of its adversely classified loans totaling $80 million and identified $52 million which were considered impaired. Of those $52 million in impaired loans, $40 million were individually evaluated to determine if valuation adjustments, or partial write-downs, should be recorded, or if specific impairment reserves should be established. The $40 million had original carrying values of $43 million which have been reduced by partial write-downs totaling $3 million. In addition to these write-downs, in order to bring the impaired loan balances to fair value, Banner has also established $3 million in specific reserves on these impaired loans. Impaired loans that were collectively evaluated for reserve purposes within homogenous pools totaled $12 million and were found to require allowances totaling $229,000. The valuation inputs for impaired loans are considered to be Level 3 inputs.

The Company records REO (acquired through a lending relationship) at fair value on a non-recurring basis. All REO properties are recorded at the lower of the estimated fair value of the properties, less expected selling costs, or the carrying amount of the defaulted loans. From time to time, non-recurring fair value adjustments to REO are recorded to reflect partial write-downs based on an observable market price or current appraised value of property. Banner considers any valuation inputs related to REO to be Level 3 inputs. The individual carrying values of these assets are reviewed for impairment at least annually and any additional impairment charges are expensed to operations. For the three months

43

ended March 31, 2015, the Company recognized no impairment charges related to REO assets, compared to $37,000 for the same quarter one year earlier.

The following tables present financial assets measured at fair value on a non-recurring basis and the level within the fair value hierarchy of the fair value measurements for those assets as of March 31, 2015 and December 31, 2014 (in thousands):

	At or For the Three Months Ended March 31, 2015
	Level 1		Level 2		Level 3		Total		Net Gains/(Losses) Recognized During the Period
Impaired loans	$	—	$	—	$	13,970	$	13,970	$	(649	)

Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs (Level 3):

The following table provides a description of the valuation technique, unobservable inputs, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring and nonrecurring basis at March 31, 2015 and December 31, 2014:

			Weighted Average Rate
Financial Instruments	Valuation Techniques	Unobservable Inputs	March 31, 2015		December 31, 2014
TPS securities	Discounted cash flows	Discount rate	5.27	%	5.26	%
TRUP CDOs	Discounted cash flows	Discount rate	4.02		3.96
Junior subordinated debentures	Discounted cash flows	Discount rate	5.27		5.26
Impaired loans	Collateral Valuations	Market values	n/a		n/a
REO	Appraisals	Market values	n/a		n/a

TPS and TRUP CDOs: Management believes that the credit risk-adjusted spread used to develop the discount rate utilized in the fair value measurement of TPS and TRUP CDOs is indicative of the risk premium a willing market participant would require under current market conditions for instruments with similar contractual rates and terms and conditions and issuers with similar credit risk profiles and with similar expected probability of default. Management attributes the change in fair value of these instruments, compared to their par value, primarily to perceived general market adjustments to the risk premiums for these types of assets subsequent to their issuance.

Junior subordinated debentures: Similar to the TPS and TRUP CDOs discussed above, management believes that the credit risk-adjusted spread utilized in the fair value measurement of the junior subordinated debentures is indicative of the risk premium a willing market participant would require under current market conditions for an issuer with Banner's credit risk profile. Management attributes the change in fair value of the junior subordinated debentures, compared to their par value, primarily to perceived general market adjustments to the risk premiums for these types of liabilities subsequent to their issuance. Future contractions in the risk adjusted spread relative to the spread currently utilized to measure the Company's junior subordinated debentures at fair value as of March 31, 2015, or the passage of time, will result in negative fair value adjustments. At March 31, 2015, the discount rate utilized was based on a credit spread of 500 basis points and three-month LIBOR of 27 basis points.

Impaired loans: Loans are considered impaired when, based on current information and events, management determines that it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Factors involved in determining impairment include, but are not limited to, the financial condition of the borrower, the value of the underlying collateral and the current status of the economy. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of collateral if the loan is collateral dependent. If this

44

practical expedient is used, the impaired loans are considered to be held at fair value. Subsequent changes in the value of impaired loans are included within the provision for loan losses in the same manner in which impairment initially was recognized or as a reduction in the provision that would otherwise be reported.

REO: Fair value adjustments on REO are based on updated real estate appraisals which are based on current market conditions.

Fair Values of Financial Instruments:

The following table presents estimated fair values of the Company’s financial instruments as of March 31, 2015 and December 31, 2014, whether or not measured at fair value in the consolidated Statements of Financial Condition.  The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies.  However, considerable judgment is necessary to interpret market data in the development of the estimates of fair value.  Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange.  The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.  The carrying value and estimated fair value of financial instruments are as follows (in thousands):

	March 31, 2015				December 31, 2014
	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value

Fair value estimates, methods, assumptions and the level within the fair value hierarchy of the fair value measurements are set forth below for the Company’s financial and off-balance-sheet instruments:

Cash and Due from Banks:  The carrying amount of these items is a reasonable estimate of their fair value. These values are considered Level 1 measures.

Securities:  The estimated fair values of investment securities and mortgaged-backed securities are priced using current active market quotes, if available, which are considered Level 1 measurements.  For most of the portfolio, matrix pricing based on the securities’ relationship to other benchmark quoted prices is used to establish the fair value.  These measurements are considered Level 2.  Due to the continued credit concerns in the capital markets and inactivity in the trust preferred markets that have limited the observability of market spreads for some of the Company’s TPS and TRUP CDO securities (see earlier discussion above in determining the securities’ fair market value), management has classified these securities as a Level 3 fair value measure.

Loans Receivable:  Fair values are estimated first by stratifying the portfolios of loans with similar financial characteristics.  Loans are segregated by type such as multifamily real estate, residential mortgage, nonresidential mortgage, commercial/agricultural, consumer and other.  Each loan category is further segmented into fixed- and adjustable-rate interest terms and by performing and non-performing categories.  A preliminary estimate of fair value is then calculated based on discounted cash flows using as a discount rate the current rate offered on similar products, plus an adjustment for liquidity to reflect the non-homogeneous nature of the loans.  The preliminary estimate is then further reduced by the amount

45

of the allowance for loan losses to arrive at a final estimate of fair value.  Fair value for significant non-performing loans is also based on recent appraisals or estimated cash flows discounted using rates commensurate with risk associated with the estimated cash flows.  Assumptions regarding credit risk, cash flows and discount rates are judgmentally determined using available market information and specific borrower information.  Management considers this to be a Level 2 measure.

FHLB Stock:  The fair value is based upon the redemption value of the stock which equates to its carrying value.  This fair value is considered a Level 3 measure.

Mortgage Servicing Rights:  Fair values are estimated based on current pricing for sales of servicing for new loans adjusted up or down based on the serviced loan’s interest rate versus current new loan rates.  Management considers this to be a Level 3 measure.

Deposit Liabilities:The fair value of deposits with no stated maturity, such as savings and checking accounts, is estimated by applying decay rate assumptions to segregated portfolios of similar deposit types to generate cash flows which are then discounted using short-term market interest rates.  The market value of certificates of deposit is based upon the discounted value of contractual cash flows.  The discount rate is determined using the rates currently offered on comparable instruments. Fair value estimates for deposits are considered Level 3 measures.

FHLB Advances and Other Borrowings:  Fair valuations for Banner’s FHLB advances are estimated using fair market values provided by the lender, the FHLB of Seattle.  The FHLB of Seattle prices advances by discounting the future contractual cash flows for individual advances using its current cost of funds curve to provide the discount rate.  This is considered to be a Level 2 input method.  Other borrowings are priced using discounted cash flows to the date of maturity based on using current rates at which such borrowings can currently be obtained. This fair value is considered to be a Level 3 measure.

Junior Subordinated Debentures:  Due to continued credit concerns in the capital markets and inactivity in the trust preferred markets that have limited the observability of market spreads (see earlier discussion above in determining the junior subordinated debentures’ fair market value), junior subordinated debentures have been classified as a Level 3 fair value measure.  Management believes that the credit risk adjusted spread and resulting discount rate utilized is indicative of those that would be used by market participants.

Derivatives:  Derivatives include interest rate swap agreements, interest rate lock commitments to originate loans held for sale and forward sales contracts to sell loans and securities related to mortgage banking activities. Fair values for these instruments, which generally change as a result of changes in the level of market interest rates, are estimated based on dealer quotes and secondary market sources. Management considers these to be Level 2 inputs.

Off-Balance Sheet Items: Off-balance sheet financial instruments include unfunded commitments to extend credit, including standby letters of credit, and commitments to purchase investment securities. The fair value of these instruments is not considered to be material. Other commitments to fund loans totaled $1.328 billion and $1.197 billion at March 31, 2015 and December 31, 2014, respectively, and have no carrying value at both dates, representing the cost of such commitments. There were no commitments to purchase securities at March 31, 2015 or at December 31, 2014.

Limitations: The fair value estimates presented herein are based on pertinent information available to management as of March 31, 2015 and December 31, 2014.  Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date and, therefore, current estimates of fair value may differ significantly from the amounts presented herein.

Fair value estimates are based on existing on- and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business.  The fair value has not been estimated for assets and liabilities that are not considered financial instruments.  Significant assets and liabilities that are not financial instruments include the deferred tax assets/liabilities; land, buildings and equipment; costs in excess of net assets acquired; and real estate held for sale.

Note 12:  INCOME TAXES AND DEFERRED TAXES

The Company files a consolidated income tax return including all of its wholly-owned subsidiaries on a calendar year basis. Income taxes are accounted for using the asset and liability method. Under this method, a deferred tax asset or liability is determined based on the enacted tax rates which will be in effect when the differences between the financial statement carrying amounts and tax bases of existing assets and liabilities are expected to be reported in the Company’s income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period of change. A valuation allowance is recognized as a reduction to deferred tax assets when management determines it is more likely than not that deferred tax assets will not be available to offset future income tax liabilities.

Accounting standards for income taxes prescribe a recognition threshold and measurement process for financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in a tax return, and also provide guidance on the de-recognition of previously recorded benefits and their classification, as well as the proper recording of interest and penalties, accounting in interim periods, disclosures and transition. The Company periodically reviews its income tax positions based on tax laws and regulations and financial reporting considerations, and records adjustments as appropriate. This review takes into consideration the status of current taxing authorities’ examinations of the Company’s tax returns, recent positions taken by the taxing authorities on similar transactions, if any, and the overall tax environment.

46

As of March 31, 2015, the Company had an insignificant amount of unrecognized tax benefits for uncertain tax positions, none of which would materially affect the effective tax rate if recognized. The Company does not anticipate that the amount of unrecognized tax benefits will significantly increase or decrease in the next twelve months. The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in the income tax expense. The Company files consolidated income tax returns in U.S. federal jurisdiction and in the Oregon and Idaho state jurisdictions. The tax years which remain subject to examination by the taxing authorities are the years ended December 31, 2013, 2012, and 2011.

Tax credit investments: The Company invests in low income housing tax credit funds that are designed to generate a return primarily through the realization of federal tax credits. As discussed more thoroughly in Note 3, the Company accounts for this in accordance with ASU 2014-01 and has applied it to all periods presented. The cost of tax credit investments is amortized over the life of the investment using a proportional amortization method and tax credit investment amortization expense is a component of provision for income taxes.

The following table presents the balances of the Company’s tax credit investments and related unfunded commitments at March 31, 2015 and 2014 (in thousands):

	March 31,
	2015		2014
Tax credit investments	$	5,948	$	5,421
Unfunded commitments—tax credit investments	2,690		3,085

The following table presents other information related to the Company's tax credit investments for the three months ended March 31, 2015 and 2014 (in thousands):

	Three Months Ended March 31,
	2015		2014
Tax credits and other tax benefits recognized	$	319	$	205
Tax credit amortization expense included in provision for income taxes	244		174

Note 13:  CALCULATION OF WEIGHTED AVERAGE SHARES OUTSTANDING FOR EARNINGS PER SHARE (EPS)

The following table reconciles basic to diluted weighted shares outstanding used to calculate earnings per share data dollars and shares (in thousands, except per share data):

	Three Months Ended March 31
	2015		2014
Net income	$	12,134	$	10,549
Basic weighted average shares outstanding	19,761		19,346
Plus unvested restricted stock	84		64
Diluted weighted shares outstanding	19,845		19,410
Earnings per common share
Basic	$	0.61	$	0.55
Diluted	$	0.61	$	0.54

Options to purchase an additional 19,964 shares of common stock as of March 31, 2015 were not included in the computation of diluted earnings per share because their exercise price resulted in them being anti-dilutive. Also, as of March 31, 2015, the warrants originally issued to the U.S. Treasury in the fourth quarter of 2008 to purchase up to $18.6 million (243,998 shares, post reverse-split) of common stock were not included in the computation of diluted EPS for the quarters ended March 31, 2015 and 2014 because the exercise price of the warrants was greater than the average market price of common shares. In June 2013, the Treasury sold the warrants in a public auction. That sale did not change the Company's capital position and did not have any impact on the financial accounting and reporting for these securities.

Note 14:  STOCK-BASED COMPENSATION PLANS

The Company operates the following stock-based compensation plans as approved by the shareholders: the 1998 Stock Option Plan, and 2001 Stock Option Plan (collectively the SOPs), the 2012 Restricted Stock and Incentive Bonus Plan, and the 2014 Omnibus Incentive Plan. In addition, the Board approved in 2006 the Long Term Incentive Plan. The purpose of these plans is to promote the success and enhance the value of the Company by providing a means for attracting and retaining highly skilled employees, officers and directors of Banner Corporation and

47

its affiliates and linking their personal interests with those of the Company's shareholders. Under these plans the Company currently has outstanding restricted stock grants, stock options and stock appreciation rights.

Restricted Stock Grants: Under the 2012 Restricted Stock and Incentive Bonus Plan, which was initially approved on April 24, 2012, the Company is authorized to issue up to 300,000 shares of its common stock to provide a means for attracting and retaining highly skilled officers of Banner Corporation and its affiliates. Shares granted under the Plan have a minimum vesting period of three years. The Plan will continue in effect for a term of ten years, after which no further awards may be granted. The 2012 Restricted Stock Plan was amended on April 23, 2013 to provide for the ability to grant (1) cash-denominated incentive-based awards payable in cash or common stock, including those that are eligible to qualify as qualified performance-based compensation for the purposes of Section 162(m) of the Code and (2) restricted stock awards that qualify as qualified performance-based compensation for the purposes of Section 162(m) of the Code. Vesting requirements may include time-based conditions, performance-based conditions, or market-based conditions. As of March 31, 2015, the Company had granted 299,997 shares of restricted stock from the 2012 Restricted Stock and Incentive Bonus Plan, of which 101,541 shares had vested and 198,456 shares remain unvested.

Banner Corporation 2014 Omnibus Incentive Plan: The 2014 Plan was approved by shareholders on April 22, 2014. The 2014 Plan provides for the grant of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units, other stock-based awards and other cash awards, and provides for vesting requirements which may include time-based or performance-based conditions. The Company has reserved 900,000 shares of its common stock for issuance under the 2014 Plan in connection with exercise of awards. As of March 31, 2015, 66,430 shares had been granted under the 2014 Omnibus Plan of which none have vested.

The expense associated with all restricted stock grants was $671,000 and $473,000 for the three-month period ended March 31, 2015 and 2014, respectively. Unrecognized compensation expense for these awards as of March 31, 2015 was $6.9 million and will be amortized over the next 36 months.

Stock Options. Under the SOPs, Banner reserved 2,284,186 shares for issuance pursuant to the exercise of stock options to be granted to directors and employees. Authority to grant additional options under the 1998 Stock Option Plan terminated on July 24, 2008. Authority to grant additional options under the 2001 Stock Option Plan terminated on April 20, 2011. The exercise price of the stock options is set at 100% of the fair market value of the stock price on the date of grant. Options granted vest at a rate of 20% per year from the date of grant and any unexercised incentive stock options will expire ten years after date of grant or 90 days after employment or service ends.

During the three months ended March 31, 2015 and 2014, the Company did not grant any stock options. Additionally, there were no significant modifications made to any stock option grants during the period. The fair values of stock options granted are amortized as compensation expense on a straight-line basis over the vesting period of the grant.

There were no stock-based compensation costs related to the SOPs for the quarters ended March 31, 2015 or March 31, 2014. The SOPs’ stock option grant compensation costs are generally based on the fair value calculated from the Black-Scholes option pricing on the date of the grant award. The Black-Scholes model assumes an expected stock price volatility based on the historical volatility at the date of the grant and an expected term based on the remaining contractual life of the vesting period. The Company bases the estimate of risk-free interest rate on the U.S. Treasury Constant Maturities Indices in effect at the time of the grant. The dividend yield is based on the current quarterly dividend in effect at the time of the grant.

During the three months ended March 31, 2015 and 2014, there were no exercises of stock options. Cash was not used to settle any equity instruments previously granted. The Company issues shares from authorized but unissued shares upon the exercise of stock options. The Company does not currently expect to repurchase shares from any source to satisfy such obligations under the SOPs.

Banner Corporation Long-Term Incentive Plan: In June 2006, the Board of Directors adopted the Banner Corporation Long-Term Incentive Plan effective July 1, 2006. The Plan is an account-based type of benefit, the value of which is directly related to changes in the value of Company common stock, dividends declared on Company common stock and changes in Banner Bank’s average earnings rate, and is considered a stock appreciation right (SAR). Each SAR entitles the holder to receive cash upon vesting, equal to the excess of the fair market value of a share of the Company’s common stock on the date of maturity of the SAR over the fair market value of such share on the date granted. The primary objective of the Plan is to create a retention incentive by allowing officers who remain with the Company or the Banks for a sufficient period of time to share in the increases in the value of Company stock. The Company re-measures the fair value of SARs each reporting period until the award is settled and recognizes changes in fair value and vesting in compensation expense.

The Company recognized a net a net reversal of compensation expense of $105,000 for the three months ended March 31, 2015 due to variations in market value of the underlying stock, compared to compensation expense of $149,000 for the three months ended March 31, 2014. At March 31, 2015, the aggregate liability related to SARs was $44,000 and was included in deferred compensation.

Note 15:  COMMITMENTS AND CONTINGENCIES

Lease Commitments — The Company leases 66 sites under non-cancelable operating leases. The leases contain various provisions for increases in rental rates, based either on changes in the published Consumer Price Index or a predetermined escalation schedule. Substantially all of the leases provide the Company with the option to extend the lease term one or more times following expiration of the initial term.

48

Financial Instruments with Off-Balance-Sheet Risk — The Company has financial instruments with off-balance-sheet risk generated in the normal course of business to meet the financing needs of our customers.  These financial instruments include commitments to extend credit, commitments related to standby letters of credit, commitments to originate loans, commitments to sell loans, commitments to buy and sell securities.  These instruments involve, to varying degrees, elements of credit and interest rate risk similar to the risk involved in on-balance sheet items recognized in our Consolidated Statements of Financial Condition.

Our exposure to credit loss in the event of nonperformance by the other party to the financial instrument from commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments.  We use the same credit policies in making commitments and conditional obligations as for on-balance-sheet instruments.

Outstanding commitments for which no asset or liability for the notional amount has been recorded consisted of the following at the dates indicated (in thousands):

	Contract or Notional Amount
	March 31, 2015		December 31, 2014
Commitments to extend credit	$	1,275,871	$	1,166,165
Standby letters of credit and financial guarantees	10,584		9,934
Commitments to originate loans	41,880		20,988
Derivatives also included in Note 16:
Commitments to originate loans held for sale	62,093		29,851
Commitments to sell loans secured by one- to four-family residential properties	21,040		8,714
Commitments to sell securities related to mortgage banking activities	43,572		25,000

Commitments to extend credit are agreements to lend to a customer, as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Many of the commitments may expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case-by-case basis.  The amount of collateral obtained, if deemed necessary upon extension of credit, is based on management’s credit evaluation of the customer. The type of collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, and income producing commercial properties.

Standby letters of credit are conditional commitments issued to guarantee a customer’s performance or payment to a third party.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Interest rates on residential one- to four-family mortgage loan applications are typically rate locked (committed) to customers during the application stage for periods ranging from 30 to 60 days, the most typical period being 45 days. Traditionally these loan applications with rate lock commitments had the pricing for the sale of these loans locked with various qualified investors under a best-efforts delivery program at or near the time the interest rate is locked with the customer. The Company then attempts to deliver these loans before their rate locks expired. This arrangement generally required delivery of the loans prior to the expiration of the rate lock. Delays in funding the loans required a lock extension. The cost of a lock extension at times was borne by the customer and at times by the Bank. These lock extension costs have not had a material impact to our operations. In 2012, the Company also began entering into forward commitments at specific prices and settlement dates to deliver either: (1) residential mortgage loans for purchase by secondary market investors (i.e., Freddie Mac or Fannie Mae), or (2) mortgage-backed securities to broker/dealers. The purpose of these forward commitments is to offset the movement in interest rates between the execution of its residential mortgage rate lock commitments with borrowers and the sale of those loans to the secondary market investor. There were nocounterparty default losses on forward contracts in the three months ended March 31, 2015 or March 31, 2014. Market risk with respect to forward contracts arises principally from changes in the value of contractual positions due to changes in interest rates. We limit our exposure to market risk by monitoring differences between commitments to customers and forward contracts with market investors and securities broker/dealers. In the event we have forward delivery contract commitments in excess of available mortgage loans, the transaction is completed by either paying or receiving a fee to or from the investor or broker/dealer equal to the increase or decrease in the market value of the forward contract.

Legal Proceedings — In the normal course of business, the Company and/or its subsidiaries have various legal proceedings and other contingent matters outstanding. These proceedings and the associated legal claims are often contested and the outcome of individual matters is not always predictable. The claims and counter-claims typically arise during the course of collection efforts on problem loans or with respect to action to enforce liens on properties in which the Company holds a security interest. Based on information known to management at this time, the Company is not a party to any legal proceedings that management believes would have a material adverse effect on the Company's results of operations or consolidated financial position at March 31, 2015.

NOTE 16: DERIVATIVES AND HEDGING

The Company, through its Banner Bank subsidiary, is party to various derivative instruments that are used for asset and liability management and customer financing needs. Derivative instruments are contracts between two or more parties that have a notional amount and an underlying variable, require no net investment and allow for the net settlement of positions. The notional amount serves as the basis for the payment

49

provision of the contract and takes the form of units, such as shares or dollars. The underlying variable represents a specified interest rate, index, or other component. The interaction between the notional amount and the underlying variable determines the number of units to be exchanged between the parties and influences the market value of the derivative contract. The Company obtains dealer quotations to value its derivative contracts.

The Company's predominant derivative and hedging activities involve interest rate swaps related to certain term loans and forward sales contracts associated with mortgage banking activities. Generally, these instruments help the Company manage exposure to market risk and meet customer financing needs. Market risk represents the possibility that economic value or net interest income will be adversely affected by fluctuations in external factors such as market-driven interest rates and prices or other economic factors.

Derivatives Designated in Hedge Relationships

The Company's fixed rate loans result in exposure to losses in value or net interest income as interest rates change. The risk management objective for hedging fixed rate loans is to effectively convert the fixed rate received to a floating rate. The Company has hedged exposure to changes in the fair value of certain fixed rate loans through the use of interest rate swaps. For a qualifying fair value hedge, changes in the value of the derivatives are recognized in current period earnings along with the corresponding changes in the fair value of the designated hedged item attributable to the risk being hedged.

In a program brought to Banner Bank through its merger with F&M Bank in 2007, customers received fixed interest rate commercial loans and Banner Bank subsequently hedged that fixed rate loan by entering into an interest rate swap with a dealer counterparty. Banner Bank receives fixed rate payments from the customers on the loans and makes similar fixed rate payments to the dealer counterparty on the swaps in exchange for variable rate payments based on the one-month LIBOR index. Some of these interest rate swaps are designated as fair value hedges. Through application of the “short cut method of accounting,” there is an assumption that the hedges are effective. Banner Bank discontinued originating interest rate swaps under this program in 2008.

As of March 31, 2015 and December 31, 2014, the notional values or contractual amounts and fair values of the Company's derivatives designated in hedge relationships were as follows (in thousands):

Derivatives Not Designated in Hedge Relationships

Interest Rate Swaps. Banner Bank has been using an interest rate swap program for commercial loan customers, termed the Back-to-Back Program, since 2010. In the Back-to-Back Program, Banner Bank provides the client with a variable rate loan and enters into an interest rate swap in which the client receives a variable rate payment in exchange for a fixed rate payment. Banner Bank offsets its risk exposure by entering into an offsetting interest rate swap with a dealer counterparty for the same notional amount and length of term as the client interest rate swap providing the dealer counterparty with a fixed rate payment in exchange for a variable rate payment. There are also a few interest rate swaps from prior to 2009 that were not designated in hedge relationships that are included in these totals. These swaps do not qualify as designated hedges; therefore, each swap is accounted for as a free standing derivative.

Mortgage Banking. In the normal course of business, the Company sells originated mortgage loans into the secondary mortgage loan markets. During the period of loan origination and prior to the sale of the loans in the secondary market, the Company has exposure to movements in interest rates associated with written rate lock commitments with potential borrowers to originate loans that are intended to be sold and for closed loans that are awaiting sale and delivery into the secondary market.

Written loan commitments that relate to the origination of mortgage loans that will be held for resale are considered free-standing derivatives and do not qualify for hedge accounting. Written loan commitments generally have a term of up to 60 days before the closing of the loan. The loan commitment does not bind the potential borrower to enter into the loan, nor does it guarantee that the Company will approve the potential borrower for the loan. Therefore, when determining fair value, the Company makes estimates of expected “fallout” (loan commitments not expected to close), using models which consider cumulative historical fallout rates, current market interest rates and other factors.

Written loan commitments in which the borrower has locked in an interest rate results in market risk to the Company to the extent market interest rates change from the rate quoted to the borrower. The Company economically hedges the risk of changing interest rates associated with its interest rate lock commitments by entering into forward sales contracts.

50

Mortgage loans which are held for sale are subject to changes in fair value due to fluctuations in interest rates from the loan's closing date through the date of sale of the loans into the secondary market. Typically, the fair value of these loans declines when interest rates increase and rises when interest rates decrease. To mitigate this risk, the Company enters into forward sales contracts on a significant portion of these loans to provide an economic hedge against those changes in fair value. Mortgage loans held for sale and the forward sales contracts are recorded at fair value with changes in value recorded in current earnings within mortgage banking operations.

As of March 31, 2015 and December 31, 2014, the notional values or contractual amounts and fair values of the Company's derivatives not designated in hedge relationships were as follows (in thousands):

Gains (losses) recognized in income on non-designated hedging instruments for the three months ended March 31, 2015 and 2014 were as follows (in thousands):

		Three Months Ended March 31

Mortgage loan commitments	Mortgage banking operations	$	412		$	70
Forward sales contracts	Mortgage banking operations	(140		)	(66		)
		$	272		$	4

The Company is exposed to credit-related losses in the event of nonperformance by the counterparty to these agreements. Credit risk of the financial contract is controlled through the credit approval, limits, and monitoring procedures and management does not expect the counterparties to fail their obligations.

In connection with the interest rate swaps between Banner Bank and the dealer counterparties, the agreements contain a provision where if Banner Bank fails to maintain its status as a well/adequately capitalized institution, then the counterparty could terminate the derivative positions and Banner Bank would be required to settle its obligations. Similarly, Banner Bank could be required to settle its obligations under certain of its agreements if specific regulatory events occur, such as a publicly issued prompt corrective action directive, cease and desist order, or a capital maintenance agreement that required Banner Bank to maintain a specific capital level. If Banner Bank had breached any of these provisions at March 31, 2015 or December 31, 2014, it could have been required to settle its obligations under the agreements at the termination value. As of March 31, 2015 and December 31, 2014, the termination value of derivatives in a net liability position related to these agreements was $8.8 million and $6.3 million, respectively. The Company generally posts collateral against derivative liabilities in the form of government agency-issued bonds, mortgage-backed securities, or commercial mortgage-backed securities. Collateral posted against derivative liabilities was $13.4 million and $11.1 million as of March 31, 2015 and December 31, 2014, respectively.

Derivative assets and liabilities are recorded at fair value on the balance sheet and do not take into account the effects of master netting agreements. Master netting agreements allow the Company to settle all derivative contracts held with a single counterparty on a net basis and to offset net derivative positions with related collateral where applicable.

ITEM 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Executive Overview

We are a bank holding company incorporated in the State of Washington which owns two subsidiary banks, Banner Bank and Islanders Bank. Banner Bank is a Washington-chartered commercial bank that conducts business from its main office in Walla Walla, Washington and, as of March 31, 2015, its 100 branch offices and ten loan production offices located in Washington, Oregon and Idaho.  Islanders Bank is also a Washington-chartered commercial bank and conducts its business from three locations in San Juan County, Washington.  Banner Corporation is subject to regulation by the Board of Governors of the Federal Reserve System (the Federal Reserve Board).  Banner Bank and Islanders Bank (the Banks) are subject to regulation by the Washington State Department of Financial Institutions, Division of Banks and the Federal Deposit Insurance Corporation (the FDIC).  As of March 31, 2015, we had total consolidated assets of $5.2 billion, total loans of $4.1 billion, total deposits of $4.3 billion and total stockholders’ equity of $651 million.

Banner Bank is a regional bank which offers a wide variety of commercial banking services and financial products to individuals, businesses and public sector entities in its primary market areas.  Islanders Bank is a community bank which offers similar banking services to individuals, businesses and public entities located in the San Juan Islands.  The Banks’ primary business is that of traditional banking institutions, accepting deposits and originating loans in locations surrounding their offices in portions of Washington, Oregon and Idaho.  Banner Bank is also an active participant in the secondary market, engaging in mortgage banking operations largely through the origination and sale of one- to four-family residential loans.  Lending activities include commercial business and commercial real estate loans, agriculture business loans, construction and land development loans, one- to four-family residential loans and consumer loans.

Banner Corporation's successful execution of its strategic plan and operating initiatives continued in the first quarter of 2015, as evidenced by our solid operating results and profitability which resulted in an annualized return on average assets of 1.02%. Over the past five years we have significantly added to our client relationships and account base, as well as substantially improved our risk profile by aggressively managing and reducing our problem assets, which has resulted in stronger and sustainable revenues and lower credit costs, and we believe has positioned the Company well for continued success.

For the quarter ended March 31, 2015, our net income was $12.1 million, or $0.61 per diluted share, compared to net income of $10.6 million, or $0.54 per diluted share, for the quarter ended March 31, 2014. Highlights for the quarter included additional loan growth, significantly increased core deposits (transaction and savings accounts), additional client acquisition, solid asset quality, and strong revenues from core operations. Compared to the same period a year ago, we had a significant increase in net interest income as well as substantial increases in deposit fees and service charges and in revenue from mortgage banking. The current quarter was also highlighted by completion of the acquisition of Siuslaw Financial Group (Siuslaw) and its subsidiary, Siuslaw Bank, expanding our presence in Oregon and complementing our purchase in June 2014 of six branches in southwestern Oregon (the Branch Acquisition). As a result of the Siuslaw acquisition, on March 6, 2015, the Company acquired approximately $370 million in total assets, $316 million in deposits, $247 million in loans and more than 8,000 new customer relationships.

Our operating results depend primarily on our net interest income, which is the difference between interest income on interest-earning assets, consisting of loans and investment securities, and interest expense on interest-bearing liabilities, composed primarily of customer deposits and borrowings. Net interest income is primarily a function of our interest rate spread, which is the difference between the yield earned on interest-earning assets and the rate paid on interest-bearing liabilities, as well as a function of the average balances of interest-earning assets and interest-bearing liabilities. Our net interest income before provision for loan losses increased $4.2 million, or 10%, to $46.5 million for the quarter ended March 31, 2015, compared to $42.3 million for the same quarter one year earlier. This increase in net interest income reflects the significant growth in earning assets and the increase in interest rate spread and net interest margin which were enhanced by continuing reductions in deposit and other funding costs. Our interest rate spread increased to 4.07% in the current quarter from 4.04% in the quarter ended March 31, 2014 while our net interest margin increased to 4.09% in the current quarter compared to 4.07% in the same quarter a year earlier.

Our net income also is affected by the level of our other operating income, including deposit fees and service charges, loan origination and servicing fees, and gains and losses on the sale of loans and securities, as well as credit costs and our non-interest operating expenses and income tax provisions.  In addition, our net income is affected by the net change in the valuation of certain financial instruments carried at fair value and in certain periods by other-than-temporary impairment (OTTI) charges or recoveries and acquisition-related bargain purchase gains and costs.  (See Note 11 of the Selected Notes to the Consolidated Financial Statements.)

Our total other operating income, which includes gains and losses on the sale of securities and changes in the value of financial instruments carried at fair value, was $13.7 million for the quarter ended March 31, 2015, compared to $9.0 million for the quarter ended March 31, 2014. For the quarter ended March 31, 2015, we recorded a net fair value gain of $1.1 million in fair value adjustments and $510,000 in losses on the sale of securities. In comparison, for the quarter ended March 31, 2014, we recorded a net fair value loss of $255,000, partially offset by $35,000 in gains on the sale of securities. Other operating income excluding the gain on sale of securities and changes in the fair value of financial instruments, which we believe is more indicative of our core operations, increased 42% to $13.2 million for the quarter ended March 31, 2015, compared to $9.3 million for the same quarter a year earlier, as a result of meaningfully increased deposit fees and service charges fueled by growth in non-interest-bearing deposit accounts and substantially increased revenues from our mortgage banking operations.

Our total revenues (net interest income before the provision for loan losses plus total other operating income) for the first quarter of 2015 increased $8.9 million to $60.2 million, compared to $51.4 million for the same period a year earlier, as a result of increased net interest income and deposit fees and service charges, positive changes in fair value adjustments, as well as increased mortgage banking revenues.  Our total revenues,

53

excluding changes in the fair value of financial instruments and loss on sale of securities, which we believe are more indicative of our core operations, also were strong at $59.7 million for the quarter ended March 31, 2015, an $8.1 million, or 16% increase, compared to $51.6 million for the same period a year earlier.  

Our other operating expenses increased in the first quarter of 2015 compared to a year earlier largely as a result of acquisition-related expenses and the costs associated with 16 branches acquired in June 2014 and March 2015, as well as generally increased salary and employee benefits and advertising and marketing expenses, which were partially offset by an increase in the credit for capitalized loan origination costs.  Other operating expenses were $41.9 million for the quarter ended March 31, 2015, compared to $35.6 million for the same quarter a year earlier.

As a result of adequate reserves already in place representing 1.83% of total loans outstanding at March 31, 2015, we did not record a provision for loan losses in the three months ended March 31, 2015, which was the ninth consecutive quarter for which we had no provision for loan losses. Our reserves at December 31, 2014 and March 31, 2014 were 1.98% and 2.11%, respectively, of total loans outstanding. The allowance for loan losses at March 31, 2015 was $75.4 million, representing 305% of non-performing loans. Non-performing loans increased to $24.7 million at March 31, 2015, including $9.2 million from the Siuslaw acquisition, compared to $16.7 million at December 31, 2014, and increased 8% when compared to $22.9 million a year earlier. (See Note 7, Loans Receivable and the Allowance for Loan Losses, as well as “Asset Quality” below in this Form 10-Q.)

Non-GAAP financial measures: Other operating income, revenues and other earnings information excluding fair value adjustments, OTTI losses or recoveries, and gains or losses on the sale of securities and, in certain periods, acquisition-related bargain purchase gains and costs are non-GAAP financial measures.  Management has presented these and other non-GAAP financial measures in this discussion and analysis because it believes that they provide useful and comparative information to assess trends in our core operations and in understanding our capital position.  However, these non-GAAP financial measures are supplemental and are not a substitute for any analysis based on GAAP. Where applicable, we have also presented comparable earnings information using GAAP financial measures.  For a reconciliation of these non-GAAP financial measures, see the tables below.  Because not all companies use the same calculations, our presentation may not be comparable to other similarly titled measures as calculated by other companies. See “Comparison of Results of Operations for the Three Months Ended March 31, 2015 and 2014” for more detailed information about our financial performance.

The ratio of tangible common stockholders’ equity to tangible assets is also a non-GAAP financial measure. We calculate tangible common equity by excluding goodwill and other intangible assets from stockholders’ equity. We calculate tangible assets by excluding the balance of goodwill and other intangible assets from total assets. We believe that this is consistent with the treatment by our bank regulatory agencies, which exclude goodwill and other intangible assets from the calculation of risk-based capital ratios. Management believes that this non-GAAP financial measure provides information to investors that is useful in understanding the basis of our capital position (dollars in thousands).

	March 31, 2015			December 31, 2014			March 31, 2014
Stockholders’ equity (GAAP)	$	651,313		$	582,888		$	547,524

Tangible common stockholders’ equity to tangible assets (non-GAAP)	12.04		%	12.29		%	12.16		%

Loans and lending: Loans are our most significant and generally highest yielding earning assets. We attempt to maintain a portfolio of loans in a range of 90% to 95% of total deposits to enhance our revenues, while adhering to sound underwriting practices and appropriate diversification guidelines in order to maintain a moderate risk profile. We offer a wide range of loan products to meet the demands of our customers. Our lending activities are primarily directed toward the origination of real estate and commercial loans. We had meaningful loan growth in the current quarter, including $247 million of loans as a result of the Siuslaw acquisition, and at March 31, 2015 our net loan portfolio totaled $4.039 billion compared to $3.758 billion at December 31, 2014 and $3.449 billion at March 31, 2014.

Our commercial real estate loans for both owner-occupied and investment properties, including construction and development loans for these types of properties, totaled $1.612 billion, or approximately 39% of our loan portfolio at March 31, 2015. In addition, multifamily residential real estate loans, including construction and development loans for these types of properties, totaled $265 million and comprise approximately 6% of our loan portfolio. While our level of activity and investment in commercial and multifamily real estate loans has been relatively stable for many years, we have experienced an increase in new originations in recent periods resulting in growth in these loan balances. In addition, commercial real estate loans comprised a significant portion of the Siuslaw Bank loan portfolio. Commercial real estate loans increased by $180 million during the first three months of 2015 and multifamily loans increased by $37 million.

We also originate residential construction, land and land development loans and, although our portfolio balances are well below the peak levels before the financial crisis, beginning in 2011 and continuing since then we have experienced increased demand for one- to four-family construction loans. Outstanding residential construction, land and land development balances increased $5 million, or 1%, to $327 million at March 31, 2015 compared to $322 million at December 31, 2014 and increased $34 million, or 12%, compared to $293 million at March 31, 2014. Still, residential construction, land and land development loans represented only approximately 8% of our total loan portfolio at March 31, 2015.

Our commercial business lending is directed toward meeting the credit and related deposit needs of various small- to medium-sized business and agribusiness borrowers operating in our primary market areas. In recent years, our commercial business lending has also included participation in certain national syndicated loans, including shared national credits, which totaled $117 million at March 31, 2015. Commercial and agricultural business loans increased $23 million, or 2%, to $985 million at March 31, 2015, compared to $962 million at December 31, 2014, and have increased $60 million, or 6%, compared to $925 million at March 31, 2014. Commercial and agricultural business loans represented approximately 24% of our portfolio at March 31, 2015.

Our residential mortgage loan originations have been relatively strong in recent years, as exceptionally low interest rates have supported demand for loans to refinance existing debt as well as loans to finance home purchases. At March 31, 2015, our outstanding balances for residential mortgages increased $12 million to $552 million, compared to $540 million at December 31, 2014, and have increased $35 million compared to $518 million at March 31, 2014. One- to four-family residential real estate loans represented nearly 13% of our loan portfolio at March 31, 2015. Most of the one- to four-family loans that we originate are sold in the secondary markets with net gains on sales and loan servicing fees reflected in our revenues from mortgage banking.

Our consumer loan activity is primarily directed at meeting demand from our existing deposit customers. We have increased our emphasis on consumer lending in recent years, although demand for consumer loans has continued to be modest as we believe many consumers have been focused on reducing their personal debt. At March 31, 2015, consumer loans, including consumer loans secured by one- to four-family residences, increased $24 million to $373 million, compared to $349 million at December 31, 2014, and have increased $76 million compared to $297 million at March 31, 2014, with most of the increase arising from the branch and Siuslaw Bank acquisitions and from increased usage of home equity lines of credit.

Deposits: Deposits, customer retail repurchase agreements and loan repayments are the major sources of our funds for lending and other investment purposes.  We compete with other financial institutions and financial intermediaries in attracting deposits and we generally attract deposits within

56

our primary market areas. Much of the focus of our branch expansion over many years, including the Branch Acquisition and Siuslaw acquisition, and our current marketing efforts have been directed toward attracting additional deposit customer relationships and balances.  This effort has been particularly directed towards increasing transaction and savings accounts and for the past four years we have been very successful in increasing these core deposit balances. The long-term success of our deposit gathering activities is reflected not only in the growth of deposit balances, but also in increases in the level of deposit fees, service charges and other payment processing revenues compared to prior periods.

Total deposits were $4.319 billion at March 31, 2015, compared to $3.899 billion three months earlier and $3.683 billion a year ago. Non-interest-bearing account balances increased 16% to $1.505 billion at March 31, 2015, compared to $1.299 billion at December 31, 2014, and increased 37% compared to $1.096 billion a year ago largely as a result of our successful client acquisition strategies, the Branch Acquisition ($71 million) and the Siuslaw acquisition ($151 million). Interest-bearing transaction and savings accounts increased 11% to $2.037 billion at March 31, 2015, compared to $1.830 billion at December 31, 2014 and increased 21% compared to $1.682 billion a year ago, while certificates of deposit increased 1% to $778 million at March 31, 2015, compared to $771 million at December 31, 2014 and decreased 14% compared to $905 million a year earlier. Core deposits represented 82% of total deposits at March 31, 2015, compared to 75% of total deposits a year earlier.

Management’s Discussion and Analysis of Results of Operations is intended to assist in understanding our financial condition and results of operations.  The information contained in this section should be read in conjunction with the Consolidated Financial Statements and accompanying Selected Notes to the Consolidated Financial Statements contained in Item 1 of this Form 10-Q.

Summary of Critical Accounting Policies

Our significant accounting policies are described in Note 1 of the Notes to the Consolidated Financial Statements for the year ended December 31, 2014 included in the 2014 Form 10-K. Various elements of our 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 critical to an understanding of our financial statements. These policies relate to (i) the methodology for the recognition of interest income, (ii) determination of the provision and allowance for loan and lease losses, (iii) the valuation of financial assets and liabilities recorded at fair value, including OTTI losses, (iv) the valuation of intangibles, such as goodwill, core deposit intangibles and mortgage servicing rights, (v) the valuation of or recognition of deferred tax assets and liabilities, and (vi) the application of acquisition accounting standards to acquisition transactions. These policies and judgments, estimates and assumptions are described in greater detail below. Management believes that the judgments, estimates and assumptions used in the preparation of the financial statements are appropriate based on the factual circumstances at the time.  However, given the sensitivity of the financial statements to these critical accounting policies, the use of other judgments, estimates and assumptions could result in material differences in the Company’s results of operations or financial condition.  Further, subsequent changes in economic or market conditions could have a material impact on these estimates and the Company’s financial condition and operating results in future periods. There have been no significant changes in our application of accounting policies during the first three months of 2015.

Interest Income: (Note 1) 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 and the loans are then placed on nonaccrual status. All previously accrued but uncollected interest is deducted from 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 amounts owed, principal or interest, may be uncollectable. While less common, similar interest reversal and nonaccrual treatment is applied to investment securities if their ultimate collectability becomes questionable.

Provision and Allowance for Loan Losses: (Note 7) The provision for loan losses reflects the amount required to maintain the allowance for losses at an appropriate level based upon management’s evaluation of the adequacy of general and specific loss reserves. We maintain an allowance for loan losses consistent in all material respects with the GAAP guidelines outlined in ASC 450, Contingencies. We have established systematic methodologies for the determination of the adequacy of our allowance for loan losses. The methodologies are set forth in a formal policy and take into consideration the need for an overall general valuation allowance as well as specific allowances that are tied to individual problem loans. We increase our allowance for loan losses by charging provisions for probable loan losses against our income and value impaired loans consistent with the accounting guidelines outlined in ASC 310, Receivables.

The allowance for losses on loans is maintained at a level sufficient to provide for probable losses based on evaluating known and inherent risks in the loan portfolio and upon our continuing analysis of the factors underlying the quality of the loan portfolio. These factors include, among others, changes in the size and composition of the loan portfolio, delinquency rates, actual loan loss experience, current and anticipated economic conditions, detailed analysis of individual loans for which full collectability may not be assured, and determination of the existence and realizable value of the collateral and guarantees securing the loans. Realized losses related to specific assets are applied as a reduction of the carrying value of the assets and charged immediately against the allowance for loan loss reserve. Recoveries on previously charged off loans are credited to the allowance. The reserve is based upon factors and trends identified by us at the time financial statements are prepared. Although we use the best information available, future adjustments to the allowance may be necessary due to economic, operating, regulatory and other conditions beyond our control. The adequacy of general and specific reserves is based on our continuing evaluation of the pertinent factors underlying the quality of the loan portfolio as well as individual review of certain large balance loans. Loans are considered impaired when, based on current information and events, we determine that it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. Factors involved in determining impairment include, but are not limited to, the financial condition of the borrower, the value of the underlying collateral and the current status of the economy. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as a practical expedient, at the loan’s observable market price or the fair value

57

of collateral if the loan is collateral dependent. Subsequent changes in the value of impaired loans are included within the provision for loan losses in the same manner in which impairment initially was recognized or as a reduction in the provision that would otherwise be reported. Large groups of smaller-balance homogeneous loans are collectively evaluated for impairment. Loans that are collectively evaluated for impairment include residential real estate and consumer loans and, as appropriate, smaller balance non-homogeneous loans. Larger balance non-homogeneous residential construction and land, commercial real estate, commercial business loans and unsecured loans are individually evaluated for impairment.

Our methodology for assessing the appropriateness of the allowance consists of several key elements, which include specific allowances, an allocated formula allowance and an unallocated allowance. Losses on specific loans are provided for when the losses are probable and estimable. General loan loss reserves are established to provide for inherent loan portfolio risks not specifically provided for on an individual loan basis. The level of general loan loss reserves is based on analysis of potential exposures existing in our loan portfolio including evaluation of historical trends, current market conditions and other relevant factors identified by us at the time the financial statements are prepared. The formula allowance is calculated by applying loss factors to outstanding loans, excluding those loans that are subject to individual analysis for specific allowances. Loss factors are based on our historical loss experience adjusted for significant environmental considerations, including the experience of other banking organizations, which in our judgment affect the collectability of the portfolio as of the evaluation date. The unallocated allowance is based upon our evaluation of various factors that are not directly measured in the determination of the formula and specific allowances. This methodology may result in losses or recoveries differing significantly from those provided in the Consolidated Financial Statements.

While we believe the estimates and assumptions used in our determination of the adequacy of the allowance are reasonable, there can be no assurance that such estimates and assumptions will not be proven incorrect in the future, or that the actual amount of future provisions will not exceed the amount of past provisions or that any increased provisions that may be required will not adversely impact our financial condition and results of operations. In addition, the determination of the amount of the Banks’ allowance for loan losses is subject to review by bank regulators as part of the routine examination process, which may result in the adjustment of reserves based upon their judgment of information available to them at the time of their examination.

Fair Value Accounting and Measurement: (Note 11) We use fair value measurements to record fair value adjustments to certain financial assets and liabilities and to determine fair value disclosures. We include in the Notes to the Consolidated Financial Statements information about the extent to which fair value is used to measure financial assets and liabilities, the valuation methodologies used and the impact on our results of operations and financial condition. Additionally, for financial instruments not recorded at fair value we disclose, where appropriate, our estimate of their fair value. For more information regarding fair value accounting, please refer to Note 11 in the Selected Notes to the Consolidated Financial Statements in this report on Form 10-Q.

Goodwill and other Intangible Assets: (Note 9) Goodwill represents the excess of the total purchase price paid over the fair value of the assets acquired, net of the fair values of liabilities assumed, and is not amortized but is reviewed annually for impairment. Other intangible assets consists primarily of core deposit intangibles (CDI), which are amounts recorded in business combinations or deposit purchase transactions related to the value of transaction-related deposits and the value of the customer relationships associated with the deposits. Core deposit intangibles are being amortized on an accelerated basis over a weighted average estimated useful life of eight years. These assets are reviewed at least annually for events or circumstances that could impact their recoverability. These events could include loss of the underlying core deposits, increased competition or adverse changes in the economy. To the extent other identifiable intangible assets are deemed unrecoverable, impairment losses are recorded in other non-interest expense to reduce the carrying amount of the assets.

Mortgage Servicing Rights: (Note 9) Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of loans. Generally, purchased servicing rights are capitalized at the cost to acquire the rights. For sales of mortgage loans, the value of the servicing right is estimated and capitalized. Fair value is based on market prices for comparable mortgage servicing contracts. Capitalized servicing rights are reported in other assets and are amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets.

Income Taxes and Deferred Taxes:  (Note 12) The Company and its wholly-owned subsidiaries file consolidated U.S. federal income tax returns, as well as state income tax returns in Oregon and Idaho. Income taxes are accounted for using the asset and liability method. Under this method a deferred tax asset or liability is determined based on the enacted tax rates which are expected to be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company’s income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Under GAAP (ASC 740), a valuation allowance is required to be recognized if it is “more likely than not” that all or a portion of our deferred tax assets will not be realized.

Business Combinations: (Note 4) Business combinations are accounted for using the acquisition method of accounting. Under the acquisition method of accounting, assets acquired and liabilities assumed are recorded at estimated fair value at the date of acquisition. Any difference in purchase consideration over the fair value of assets acquired and liabilities assumed results in the recognition of goodwill should purchase consideration exceed net estimated fair values, or a bargain purchase gain, should estimated fair values exceed purchase consideration. Expenses incurred in connection with a business combination are expensed as incurred.

Acquired Loans:Purchased loans are recorded at their fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either purchased credit-impaired or purchased non-credit-impaired. Purchased credit-impaired loans reflect credit deterioration since origination such that it is probable at acquisition that the Company will be unable to collect all contractually required payments.

58

The cash flows expected to be received over the life of the loans were estimated by management. These cash flows were provided to third party analysts to calculate carrying values of the loans, book yields, effective interest income and impairment, if any, based on actual and projected events. Default rates, loss severity, and prepayment speed assumptions will be periodically reassessed to update our expectation of future cash flows. The excess of the cash flows expected to be collected over a loan's carrying value is considered to be the accretable yield and is recognized as interest income over the estimated life of the loan using the effective interest method. The accretable yield may change due to changes in the timing and amounts of expected cash flows. Changes in the accretable yield are disclosed quarterly.

The excess of the undiscounted contractual balances due over the cash flows expected to be collected is considered to be the non-accretable difference. The nonaccretable difference represents our estimate of the credit losses expected to occur and was considered in determining the fair value of the loans as of the acquisition date. Subsequent to the acquisition date, any increases in expected cash flows over those expected at purchase date are adjusted through a change to the accretable yield on a prospective basis. Any subsequent decreases in expected cash flows attributable to credit deterioration are recognized by recording a provision for loan losses. The purchased credit-impaired loans acquired are and will continue to be subject to the Company's internal and external credit review and monitoring.

For purchased non-impaired 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.

Comparison of Financial Condition at March 31, 2015 and December 31, 2014

General.  Total assets increased $488 million, or 10%, to $5.211 billion at March 31, 2015, from $4.723 billion at December 31, 2014.  Net loans receivable (gross loans less deferred fees and discounts, and allowance for loan losses) increased $282 million, or 7%, to $4.039 billion at March 31, 2015, from $3.758 billion at December 31, 2014. A portion of these increases resulted from the Siuslaw acquisition in which we acquired $247 million in loans and $316 million in deposits when the purchase transaction closed on March 6, 2015.

The increase in net loans included increases of $160 million in commercial real estate loans, including $126 million from the Siuslaw acquisition, $24 million in consumer loans, $41 million in multifamily loans, $53 million in commercial business loans, including $27 million from the Siuslaw acquisition, $8 million in one- to four-family construction loans, $13 million in commercial construction loans, $13 million in one- to four-family residential loans, and $3 million in land and land development loans, partially offset by decreases of $4 million in multifamily construction loans and $30 million in agricultural business loans. The increase in commercial real estate loans included $80 million for investment properties and $81 million for owner-occupied properties. The decrease in agricultural business loans represents a normal seasonal decrease for the first quarter.

The aggregate balance of interest-earning deposits and securities increased $145 million from December 31, 2014 to $782 million at March 31, 2015, largely as a result of the Siuslaw acquisition. Our total investment in securities decreased $15 million to $567 million at March 31, 2015, while interest-earning deposits increased $160 million during the three months ended March 31, 2015 to $215 million. Securities purchases during the three-month period have been modest and were primarily mortgage-backed securities and intermediate-term taxable and tax-exempt municipal securities. Securities sales have also been modest although we did sell substantially all of the securities acquired in the Siuslaw acquisition. The average effective duration of Banner's securities portfolio was approximately 2.8 years at March 31, 2015. Net fair value adjustments to the portfolio of securities held for trading, which are included in net income, were an increase of $1.4 million in the three months ended March 31, 2015. In addition, fair value adjustments for securities designated as available-for-sale reflected an increase of 2.3 million for the three months ended March 31, 2015, which was included net of the associated tax expense of $822,000 as a component of other comprehensive income and largely occurred as a result of modestly decreased market interest rates. (See Note 11 of the Selected Notes to the Consolidated Financial Statements in this Form 10-Q.)

REO increased $1.5 million, to $4.9 million at March 31, 2015, compared to $3.4 million at December 31, 2014, primarily as a result of properties acquired in the Siuslaw merger. During the three months ended March 31, 2015, we transferred $668,000 of loans into REO, acquired $2.5 million of loans in the Siuslaw acquisition, disposed of $1.7 million of REO properties recognizing $115,000 in gains related to those sales, and did not have any valuation adjustments. (See Note 8 of the Selected Notes to the Consolidated Financial Statements in this Form 10-Q and “Asset Quality” discussion below).

Deposits increased $420 million, or 11%, to $4.319 billion at March 31, 2015 from $3.899 billion at December 31, 2014, largely as a result of the Siuslaw acquisition, which accounted for $316 million of the increase for the quarter. Non-interest-bearing deposits increased by $206 million, or 16%, to $1.505 billion at March 31, 2015, compared to $1.299 billion at December 31, 2014, and have increased by 37% compared to a year earlier. Interest-bearing transaction and savings accounts increased by $207 million, or 11%, to $2.037 billion at March 31, 2015 from $1.830 billion at December 31, 2014 and have increased by 21% compared to a year earlier. Certificates of deposit increased $7 million, or 1%, to $778 million at March 31, 2015 from $771 million at December 31, 2014, and have decreased by 14% compared to a year earlier. Core deposits increased to 82% of total deposits at the end of the first quarter, compared to 75% of total deposits a year earlier. The Siuslaw acquisition resulted in a $316 million increase in deposits, including $151 million in non-interest bearing deposits, $140 million in interest-bearing transaction and savings accounts, and $25 million in certificates of deposit as of March 31, 2015.

FHLB advances decreased $32 million to $250,000 at March 31, 2015 from $32 million at December 31, 2014 as we used our excess liquidity to repay maturing FHLB advances. Other borrowings, consisting of retail repurchase agreements primarily related to customer cash management accounts, increased $20 million, or 26%, to $97 million at March 31, 2015, compared to $77 million at December 31, 2014. A junior subordinated debenture with a fair value of $6 million was acquired in the Siuslaw acquisition. No additional junior subordinated debentures were issued or matured during the quarter and in addition to the acquisition of the junior subordinated debenture the estimated fair value of these instruments increased $366,000 to $84 million at March 31, 2015 from $78 million at December 31, 2014. For more information, see Notes 10 and 11 of the Selected Notes to the Consolidated Financial Statements.

Total stockholders' equity increased $68 million, or 12%, to $651 million at March 31, 2015 compared to $583 million at December 31, 2014. The increase in equity primarily reflects the common shares issued in the Siuslaw acquisition and the year-to-date net income reduced by payment of dividends to common stockholders. In addition, there was an improvement of $1.4 million in accumulated other comprehensive income representing an unrealized gain, net of tax, on securities available-for-sale. Tangible common stockholders' equity, which excludes intangible assets, increased $44 million to $624 million, or 12.04% of tangible assets at March 31, 2015, compared to $580 million, or 12.29% of tangible assets at December 31, 2014. In the three months ended March 31, 2015, we did not have any repurchases of our common stock as part of the publicly announced repurchase plan, but 5,671 shares were surrendered by employees to satisfy tax withholding obligations upon the vesting of restricted stock grants.

Comparison of Results of Operations for the Three Months Ended March 31, 2015 and 2014

For the quarter ended March 31, 2015, net income was $12.1 million, or $0.61 per diluted share. This compares to net income of $10.5 million, or $0.54 per diluted share, for the quarter ended March 31, 2014. As expected, our current quarter operating results continued to be influenced by very low interest rates which produced downward pressure on asset yields. Nonetheless, significant growth in earning assets, as well as

60

changes in the asset mix and further reductions in funding costs combined to offset this yield pressure. In addition, credit costs remained low and deposit fees and other payment processing revenues increased compared to a year earlier reflecting further growth in client relationships. We also experienced substantial growth in mortgage banking revenues, which increased 23% to $8.1 million in the current quarter ended March 31, 2015 compared to the same period a year ago as low interest rates contributed to robust loan origination activity. As a result, net income for the current quarter ended March 31, 2015 was solid, representing further progress on our strategic priorities and initiatives, and produced an annualized return on average assets of 1.02%, an improvement from 0.97% in the comparable period a year ago.

Net Interest Income. Net interest income before provision for loan losses increased by $4.2 million, or 10%, to $46.5 million for the quarter ended March 31, 2015, compared to $42.3 million for the same quarter one year earlier, as a small increase in the net interest margin was enhanced by a $391.0 million increase in the average balance of interest-earning assets. The net interest margin of 4.09% for the quarter ended March 31, 2015 was two basis points higher than for the same quarter in the prior year. The increase in the net interest margin compared to a year earlier reflects changes in the mix of earning assets and modest reductions in deposit and funding costs, which were sufficient to offset the impact of persistently low market interest rates on earning asset yields. The accretion of discounts on the loans acquired in the Siuslaw merger added one basis point to the net interest margin in the quarter ended March 31, 2015, while nonaccrual loans reduced the net interest margin by two basis points. Nonaccrual loans also reduced the net interest margin by two basis points in the quarter ended March 31, 2014.

The net interest spread increased to 4.07% for the quarter ended March 31, 2015 compared to 4.04% for the quarter ended March 31, 2014. Reflecting generally lower market interest rates as well as changes in asset mix, the yield on interest-earning assets for the quarter ended March 31, 2015 was 4.31%, a decrease of two basis points compared to the same quarter a year earlier. While declining more than asset yields, funding costs were also only modestly lower, especially deposit costs which decreased just four basis points to 0.18% from 0.22% a year earlier, leading to a decrease of five basis points for all funding liabilities to 0.24% for the quarter ended March 31, 2015 compared to 0.29% for the quarter ended March 31, 2014.

Interest Income. Interest income for the quarter ended March 31, 2015 was $49.1 million, compared to $45.1 million for the same quarter in the prior year, an increase of $4.0 million, or 9%.  The increase in interest income occurred as a result of an increase in the average balances of interest-earning assets, which was partially offset by a decline in the yield. The average balance of interest-earning assets was $4.612 billion for the quarter ended March 31, 2015, an increase of $391 million, or 9%, compared to $4.221 billion one year earlier. The yield on average interest-earning assets decreased to 4.31% for the quarter ended March 31, 2015, compared to 4.33% for the same quarter one year earlier. The decrease in the yield on earning assets reflects the continuing erosion of yields as loans mature or prepay and are replaced by lower yielding assets in the current low interest rate environment. Average loans receivable for the quarter ended March 31, 2015 increased $445 million, or 13%, to $3.920 billion, compared to $3.475 billion for the same quarter in the prior year. Interest income on loans increased by $4.6 million, or 11%, to $46.4 million for the current quarter from $41.7 million for the quarter ended March 31, 2014, reflecting the impact of the $445 million increase in average loan balances, partially offset by a seven basis point decrease in the average yield on loans.  The average yield on loans was 4.80% for the quarter ended March 31, 2015, compared to 4.87% for the same quarter one year earlier.

The combined average balance of mortgage-backed securities, other investment securities, daily interest-bearing deposits and FHLB stock decreased to $692 million for the quarter ended March 31, 2015 (excluding the effect of fair value adjustments), compared to $746 million for the quarter ended March 31, 2014; and the interest and dividend income from those investments decreased by $659,000 compared to the same quarter in the prior year. The average yield on the combined portfolio decreased to 1.58% for the quarter ended March 31, 2015, from 1.83% for the same quarter one year earlier. The decrease in the yield on the combined portfolio was the result of a more significant portion of the portfolio being invested in daily interest-bearing deposits as well as the adverse impact of accelerated premium amortization on certain mortgage- backed securities caused by increased prepayments on the underlying loans. The yield on the combined portfolio benefited slightly from an $8 million reduction in the average balance of FHLB stock which had a very low 0.11% dividend yield. For the quarter ended March 31, 2015, the yield on mortgage-backed securities decreased 34 basis points to 1.35% compared to the quarter ended March 31, 2014, largely as a result of unanticipated prepayments on multifamily loans underlying certain securities that had significant unamortized purchase premiums. For the quarter ended March 31, 2015, the yield on other securities decreased one basis point to 2.47% compared to the quarter ended March 31, 2014.

Interest Expense. Interest expense for the quarter ended March 31, 2015 was $2.5 million, compared to $2.8 million for the same quarter in the prior year, a decrease of $234,000, or 8%. The decrease in interest expense occurred as a result of a five basis point decrease in the average cost of all funding liabilities to 0.24% for the quarter ended March 31, 2015, from 0.29% for the same quarter one year earlier, partially offset by a $348 million increase in average funding liabilities. The increase in average funding liabilities reflects increases in core deposits, including non-interest-bearing accounts, partially offset by a continued decline in the average balance of certificates of deposit as well as decreased average advances from FHLB and other borrowings compared to one year ago.

Deposit interest expense decreased $231,000, or 12%, to $1.7 million for the quarter ended March 31, 2015, compared to $2.0 million for the same quarter in the prior year, as a result of a four basis point decrease in the cost of deposits. Average deposit balances increased to $3.998 billion for the quarter ended March 31, 2015, from $3.619 billion for the quarter ended March 31, 2014, and the average rate paid on deposit balances decreased to 0.18% in the first quarter of 2015 from 0.22% for the quarter ended March 31, 2014. The cost of interest-bearing deposits decreased by five basis points to 0.26% for the quarter ended March 31, 2015 compared to 0.31% in the same quarter a year earlier. Significantly contributing to the decrease in total deposit costs was a $255 million increase in the average balances of non-interest-bearing accounts. Deposit costs are significantly affected by changes in the level of market interest rates; however, changes in the average rate paid for interest-bearing deposits frequently tend to lag changes in market interest rates as evidenced by the continuing decline in our deposit costs despite relatively stable short-term market interest rates over the past twelve months. Further, continuing changes in our deposit mix, especially growth in lower cost transaction and savings accounts, in particular non-interest-bearing deposits, have meaningfully contributed to the decrease in our funding costs compared to earlier periods.

61

Average FHLB advances (excluding the effect of fair value adjustments) were $18 million for the quarter ended March 31, 2015, compared to $50 million for the same quarter one year earlier, and the average rate paid on FHLB advances for the quarter ended March 31, 2015 decreased to 0.39% from 0.31% for the same quarter one year earlier. Interest expense on FHLB advances decreased to $17,000 for the quarter ended March 31, 2015 from $38,000 for the quarter ended March 31, 2014.

Other borrowings consist primarily of retail repurchase agreements with customers secured by certain investment securities. The average balance for other borrowings remained unchanged at $88 million for both the current quarter and the same quarter a year earlier, while the rate on other borrowings also remained unchanged at 0.20% for both periods. Likewise, interest expense for other borrowings was essentially unchanged at $43,000 for the quarter ended March 31, 2015, compared to $44,000 for the quarter ended March 31, 2014.

Junior subordinated debentures which were issued in connection with our issuance of trust preferred securities had an average balance of $126 million (excluding the effect of fair value adjustments) and an average cost of 2.38% for the quarter ended March 31, 2015. Both the average balance and average cost of these borrowings increased slightly compared to the same period a year earlier as a result of a $6 million junior subordinated debenture acquired in the Siuslaw acquisition. Junior subordinated debentures outstanding had an average balance of $124 million (excluding the effect of fair value adjustments) with lower average costs of 2.36% for the quarter ended March 31, 2014. The junior subordinated debentures are adjustable-rate instruments with repricing frequencies of three months based upon the three-month LIBOR index.

Provision and Allowance for Loan Losses. As a result of adequate reserves already in place representing 1.83% of total loans outstanding, as well as continuing strong loan performance and credit quality metrics, we did not record a provision for loan losses in the quarter ended March 31, 2015. Similarly, we did not record a provision in the quarter ended March 31, 2014. As discussed in the Summary of Critical Accounting Policies section above and in Note 1 of the Selected Notes to the Consolidated Financial Statements in this Form 10-Q, the provision and allowance for loan losses is one of the most critical accounting estimates included in our Consolidated Financial Statements.

The provision for loan losses reflects the amount required to maintain the allowance for losses at an appropriate level based upon management’s evaluation of the adequacy of general and specific loss reserves, trends in delinquencies and net charge-offs and current economic conditions. While our credit quality indicators remained solid, eliminating the need for a provision for loan losses for the first three months of 2015, reflecting lingering uncertainty in the economy, we continue to maintain a substantial allowance for loan losses at March 31, 2015.

We recorded net charge-offs of $542,000 for the quarter ended March 31, 2015, compared to net recoveries of $113,000 for the same quarter in the prior year. Non-performing loans were $25 million at March 31, 2015, including $9 million from the Siuslaw acquisition, compared to $17 million at December 31, 2014 and $23 million at March 31, 2014. A comparison of the allowance for loan losses at March 31, 2015 and 2014 reflects an increase of $1 million to $75 million at March 31, 2015, from $74 million at March 31, 2014.  Included in our allowance at March 31, 2015 was an unallocated portion of $2 million, which is based upon our evaluation of various factors that are not directly measured in the determination of the formula and specific allowances. The allowance for loan losses as a percentage of total loans (loans receivable including loans acquired in business combinations carried at fair value and excluding allowance for losses) decreased to 1.83% at March 31, 2015, from 2.11% at March 31, 2014. Further, with the increase in problem loans, the allowance as a percentage of non-performing loans (including non-performing loans acquired in business combinations) decreased to 305% at March 31, 2015, compared to 454% of non-performing loans at December 31, 2014 and 325% a year earlier.

As of March 31, 2015, we had identified $52 million of impaired loans. Impaired loans are comprised of loans on nonaccrual, TDRs that are performing under their restructured terms and loans that are 90 days or more past due, but are still on accrual. Impaired loans may be evaluated for reserve purposes using either a specific impairment analysis or collectively evaluated as part of homogeneous pools. For more information on these impaired loans, refer to Note 7 of the Selected Notes to the Consolidated Financial Statements, Loans Receivable and the Allowance for Loan Losses, and Note 11, Fair Value Accounting and Measurement, in this Form 10-Q.

We believe that the allowance for loan losses as of March 31, 2015 was adequate to absorb the known and inherent risks of loss in the loan portfolio at that date. While we believe the estimates and assumptions used in our determination of the adequacy of the allowance are reasonable, there can be no assurance that these estimates and assumptions will not be proven incorrect in the future, or that the actual amount of future provisions will not exceed the amount of past provisions or that any increased provisions that may be required will not adversely impact our financial condition and results of operations. In addition, the determination of the amount of the allowance for loan losses is subject to review by bank regulators as part of the routine examination process, which may result in the establishment of additional reserves based upon their judgment of information available to them at the time of their examination.

Other Operating Income. Other operating income, which includes changes in the valuation of financial instruments carried at fair value, OTTI charges and recoveries, and net gain or loss on sale of securities, as well as non-interest revenues from core operations, was $13.7 million for the quarter ended March 31, 2015, compared to $9.0 million for the same quarter in the prior year. Our other operating income for the three months ended March 31, 2015 included a $1.1 million net gain for fair value adjustments, which was partially offset by a $510,000 net loss on the sale of securities. The net fair value adjustment and loss on sale of securities principally related to the sale of one pooled trust preferred collateralized debt obligation security and the partial redemption of a second similar security (TRUP CDOs) which had been carried at fair value. During the quarter ended March 31, 2014, fair value adjustments resulted in a net loss of $255,000. For a more detailed discussion of our fair value adjustments, please refer to Note 11 in the Selected Notes to the Consolidated Financial Statements in this Form 10-Q.

Excluding the fair value and net gain or loss on sale of securities, other operating income from core operations increased by $3.9 million, or 42%, to $13.2 million for the quarter ended March 31, 2015, compared to $9.3 million for the quarter ended March 31, 2014, largely as a result of increased revenues from deposit fees and other service charges and increased mortgage banking income. Deposit fees and other service charges increased by $1.5 million compared to the first quarter a year ago reflecting growth in the number of deposit accounts, increased transaction activity and our decision to change our debit and credit card relationship to MasterCard^®. Mortgage banking revenues increased by $2.3 million reflecting increased mortgage refinancing activity, as well as a strong home purchase market and our increased market presence as a result of additions to our production staff.

Other Operating Expenses. Other operating expenses increased by $6.3 million, to $41.9 million for the quarter ended March 31, 2015, compared to $35.6 million for the quarter ended March 31, 2014, largely as a result of acquisition-related expenses and the costs associated with operating the 16 branches acquired in June 2014 and March 2015, as well as generally increased salary and employee benefits and advertising and marketing expenses, which were partially offset by an increase in the credit for capitalized loan origination costs. Acquisition-related costs were $1.6 million for the quarter ended March 31, 2015 compared to $45,000 in the same quarter one year ago.

Salary and employee benefits expense increased $3.1 million, or 15%, to $24.3 million for the quarter ended March 31, 2015, compared to $21.2 million for the quarter ended March 31, 2014, in part reflecting the incremental staffing associated with the Branch Acquisition in June 2014 as well as one month of expense related to the Siuslaw acquisition in March 2015. The increased expense also was the result of salary and wage adjustments and increased incentive compensation accruals, health insurance and other benefit costs and mortgage banking commissions related to the ongoing operations of the rest of the Company.

64

Partially offsetting the increase in compensation, the credit for capitalized loan origination costs increased by $643,000 compared to the same quarter a year earlier reflecting increased loan production. Advertising and marketing expenses increased $555,000, or 53%, to $1.6 million for the quarter ended March 31, 2015, compared to $1.1 million for the quarter ended March 31, 2014 as a result of increased direct mail advertising and expanded market areas, as well as certain front-loaded costs for new media campaigns. Payment and card processing expenses increased $501,000, or 20%, compared to the same period one year earlier, reflecting increased transactions as a result of the significant growth in core deposit accounts. Occupancy expense increased $310,000, or 5%, to $6.0 million for the quarter ended March 31, 2015, compared to $5.7 million for the quarter ended March 31, 2014, in part reflecting the additional branch locations from the Branch Acquisition and the Siuslaw acquisition, but also as a result of increased depreciation expense related to computer hardware and software upgrades and building repair and maintenance expenses. Information and computer data services increased $318,000, or 16%. The net charge from REO operations was $24,000 for the quarter ended March 31, 2015 compared to a net charge of $39,000 for the quarter ended March 31, 2014. Professional services expense was $192,000, 19% lower than in the prior year.

Income Taxes. In the quarter ended March 31, 2015, we recognized $6.2 million in income tax expense for an effective tax rate of 33.8%, which reflects our normal statutory tax rate increased by the effect of certain non-deductible merger expenses and reduced by the effect of tax-exempt income and certain tax credits. Our normal, expected statutory income tax rate is 36.4%, representing a blend of the statutory federal income tax rate of 35.0% and apportioned effects of the 7.6% Oregon and 7.4% Idaho income tax rates. For the quarter ended March 31, 2014, we recognized $5.2 million in income tax expense for an effective tax rate of 33.2%. For more discussion on our income taxes, please refer to Note 12 in the Selected Notes to the Consolidated Financial Statements in this report on Form 10-Q.

Asset Quality

Achieving and maintaining a moderate risk profile by employing appropriate underwriting standards, avoiding excessive asset concentrations and aggressively managing troubled assets has been and will continue to be a primary focus for us. As a result, our non-performing assets declined substantially in recent years, although our non-performing assets increased modestly during the most recent quarter as a result of $9.2 million of non-performing loans and $2.5 million of real estate owned acquired in the Siuslaw merger. While these assets acquired in the merger transaction have been recorded at fair values, including appropriate present value discounting of expected cash flows which can be interpreted as converting the loans to performing status, we have chosen to include them in our non-performing asset totals and related credit metrics to present a more complete representation of our asset quality. In addition to the discounts associated with the loans acquired in business combinations, our reserve levels are substantial and, as a result of our impairment analysis and charge-off actions, reflect current appraisals and valuation estimates. While our non-performing assets and credit costs have been materially reduced compared to past periods, we continue to be actively engaged with our borrowers in resolving remaining problem assets and with the effective management of real estate owned as a result of foreclosures.

Non-Performing Assets:  Non-performing assets increased to $30 million, or 0.57% of total assets, at March 31, 2015, from $20 million, or 0.43% of total assets, at December 31, 2014, and $26 million, or 0.59% of total assets, at March 31, 2014. Our allowance for loan losses was $75 million, or 1.83% of total loans and 305% of non-performing loans at March 31, 2015, compared to $76 million, or 1.98% of total loans and 454% of non-performing loans at December 31, 2014.  We believe our level of non-performing loans and assets, which increased modestly primarily as a result of the Siuslaw merger, is manageable and continue to believe that we have sufficient capital and human resources to manage the collection of our non-performing assets in an orderly fashion. The primary components of the $30 million in non-performing assets were $23 million in nonaccrual loans, $2 million in loans more than 90 days delinquent and still accruing interest, and $5 million in REO and other repossessed assets.

Loans are reported as restructured when we grant concessions to a borrower experiencing financial difficulties that we would not otherwise consider.  As a result of these concessions, restructured loans or TDRs are impaired as the Banks will not collect all amounts due, both principal and interest, in accordance with the terms of the original loan agreement.  If any restructured loan becomes delinquent or other matters call into question the borrower's ability to repay full interest and principal in accordance with the restructured terms, the restructured loan(s) would be reclassified as nonaccrual.  At March 31, 2015, we had $23 million of restructured loans currently performing under their restructured terms.

⁽¹⁾  Includes $2.4 million of nonaccrual restructured loans. For the three months ended March 31, 2015, $34,000 in interest income would have been recorded had nonaccrual loans been current.

(2) Real estate acquired by us as a result of foreclosure or by deed-in-lieu of foreclosure is classified as real estate held for sale until it is sold. When property is acquired, it is recorded at the lower of the estimated fair value of the property, less expected selling costs, or the carrying value of the defaulted loan. Subsequent to foreclosure, the property is carried at the lower of the foreclosed amount or net realizable value. Upon receipt of a new appraisal and market analysis, the carrying value is written down through the establishment of a specific reserve to the anticipated sales price, less selling and holding costs.

(3) These loans are performing under their restructured terms.

In addition to the non-performing loans as of March 31, 2015, we had other classified loans with an aggregate outstanding balance of $88 million that are not on nonaccrual status, with respect to which known information concerning possible credit problems with the borrowers or the cash flows of the properties securing the respective loans has caused management to be concerned about the ability of the borrowers to comply with present loan repayment terms.  This may result in the future inclusion of such loans in the nonaccrual loan category.

Within our non-performing loans, we have three non-accrual lending relationships with aggregate loan exposure in excess of $1.0 million that collectively comprise $6.7 million, or 27.2%, of our total non-performing loans as of March 31, 2015. At that date the single largest non-performing lending relationship consisted of one loan that totaled $3.6 million secured by four commercial lots in the Lane County, Oregon area. The second largest non-performing lending relationship consisted of one loan of $1.8 million secured by golf course property, business assets and fixtures in the Lane County, Oregon area. The third largest non-performing lending relationship consisted of one loan that totaled $1.3 million and is secured by a 17-acre parcel in the Lane County, Oregon area. The remaining balance of our non-performing loans consists of 133 lending relationships, each less than $1.0 million, with borrowers located throughout our market area.

We record REO (acquired through a lending relationship) at fair value on a non-recurring basis. All REO properties are recorded at the lower of the estimated fair value of the property, less estimate selling costs, or the carrying value of the loan. From time to time, non-recurring fair value adjustments to REO are recorded to reflect partial write-downs based on an observable market price or current appraised value of property. The individual carrying values of these assets are reviewed for impairment at least annually and any additional impairment charges are expensed to operations. For the quarter ended March 31, 2015, we had no impairment charges, compared to the quarter ended March 31, 2014 in which we recognized $37,000 of impairment charges related to these types of assets.

At March 31, 2015, we had $4.9 million of REO, the most significant components of which are a commercial office building with two parcels of land in the Lane County, Oregon area with a book value of $1.0 million; a single family residence also in the Lane County, Oregon area with a book value of $680,000; a subdivision in the greater Portland, Oregon area consisting of seven residential buildable lots and 33.2 acres of undeveloped land with a book value of $654,000; and one single family residence in the greater Spokane, Washington area with a book value of $535,000. All other REO holdings have individual book values of less than $500,000. The geographical distribution of REO include approximately $2.5 million in the Lane County, Oregon area, or 51% and $1.3 million in the greater Portland, Oregon area, or 27%. All other areas of Washington, Oregon and Idaho had a combined book value of $1.1 million, or 22%.

Liquidity and Capital Resources

Our primary sources of funds are deposits, borrowings, proceeds from loan principal and interest payments and sales of loans, and the maturity of and interest income on mortgage-backed and investment securities. While maturities and scheduled amortization of loans and mortgage-backed securities are a predictable source of funds, deposit flows and mortgage prepayments are greatly influenced by market interest rates, economic conditions, competition and our pricing strategies.

Our primary investing activity is the origination and purchase of loans and, in certain periods, the purchase of securities.  During the three months ended March 31, 2015 and 2014, our loan originations exceeded our loan repayments by $139 million and $121 million, respectively. During

67

those periods we purchased loans of $42 million and $54 million, respectively.  During the three months ended March 31, 2015 and 2014, we sold $148 million and $70 million, respectively, of loans.  Securities purchased during the three months ended March 31, 2015 and 2014 totaled $30 million and $39 million, respectively, and securities repayments, maturities and sales were $60 million and $43 million, respectively.  

Our primary financing activity is gathering deposits. Deposits increased by $420 million during the first three months of 2015, including an $8 million increase in certificates of deposits. The Siuslaw acquisition contributed $316 million to the increase in deposits, including $151 million in non-interest bearing deposits, $140 million in interest-bearing transaction and savings accounts, and $25 million in certificates of deposit as of March 31, 2015. Certificates of deposits are generally more vulnerable to competition and price sensitive than other retail deposits and our pricing of those deposits varies significantly based upon our liquidity management strategies at any point in time.  At March 31, 2015, certificates of deposit amounted to $778 million, or 18% of our total deposits, including $570 million which were scheduled to mature within one year.  While no assurance can be given as to future periods, historically, we have been able to retain a significant amount of our deposits as they mature.

FHLB advances (excluding fair value adjustments) decreased $32 million from December 31, 2014 to $250,000 at March 31, 2015, and decreased $48 million from March 31, 2014 as we used our excess liquidity to repay maturing FHLB advances and increased deposits were available to fund lending needs. As of March 31, 2015, FHLB advances consisted of one long-term borrowing tied to a specific loan customer's outstanding loan balance. Other borrowings increased $20 million to $97 million for the three months ended March 31, 2015 and increased $7 million from one year ago. The increase in other borrowings in the three months ended March 31, 2015 was due to an increase of retail repurchase agreements.

We must maintain an adequate level of liquidity to ensure the availability of sufficient funds to accommodate deposit withdrawals, to support loan growth, to satisfy financial commitments and to take advantage of investment opportunities. During the three months ended March 31, 2015 and 2014, we used our sources of funds primarily to fund loan commitments, purchase securities, and pay maturing savings certificates and deposit withdrawals. At March 31, 2015, we had outstanding loan commitments totaling $1.390 billion, including undisbursed loans in process and unused credit lines totaling $1.328 billion. While representing potential growth in the loan portfolio and lending activities, this level of commitments is proportionally consistent with our historical experience and does not represent a departure from normal operations.

We generally maintain sufficient cash and readily marketable securities to meet short-term liquidity needs; however, our primary liquidity management practice to supplement deposits is to increase or decrease short-term borrowings, including FHLB advances and Federal Reserve Bank of San Francisco (FRBSF) borrowings.  We maintain credit facilities with the FHLB-Seattle, which at March 31, 2015 provide for advances that in the aggregate may equal the lesser of 35% of Banner Bank’s assets or adjusted qualifying collateral (subject to a sufficient level of ownership of FHLB stock), up to a total possible credit line of $1.1 billion, and 25% of Islanders Bank’s assets or adjusted qualifying collateral, up to a total possible credit line of $25 million.  Advances under these credit facilities (excluding fair value adjustments) totaled $250,000 at March 31, 2015. In addition, Banner Bank has been approved for participation in the FRBSF’s Borrower-In-Custody (BIC) program.  Under this program Banner Bank had available lines of credit of approximately $657 million as of March 31, 2015, subject to certain collateral requirements, namely the collateral type and risk rating of eligible pledged loans.  We had no funds borrowed from the FRBSF at March 31, 2015 or December 31, 2014.  Management believes it has adequate resources and funding potential to meet our foreseeable liquidity requirements.

Banner Corporation is a separate legal entity from the Banks and, on a stand-alone level, must provide for its own liquidity and pay its own operating expenses and cash dividends. Banner's primary sources of funds consist of capital raised through dividends or capital distributions from the Banks, although there are regulatory restrictions on the ability of the Banks to pay dividends. At March 31, 2015, the Company (on an unconsolidated basis) had liquid assets of $44.0 million.

As noted below, Banner Corporation and its subsidiary banks continued to maintain capital levels significantly in excess of the requirements to be categorized as “Well-Capitalized” under applicable regulatory standards, including the newly implemented Basel III and Dodd Frank standards.  During the three months ended March 31, 2015, total stockholders' equity increased $68 million, or 12%, to $651 million.  Total equity at March 31, 2015 is entirely attributable to common stock.  At March 31, 2015, tangible common stockholders’ equity, which excludes other goodwill and other intangible assets, was $624 million, or 12.04% of tangible assets.  See the discussion and reconciliation of non-GAAP financial information in the Executive Overview section of Management’s Discussion and Analysis of Financial Condition and Results of Operation in this Form 10-Q for more detailed information with respect to tangible common stockholders’ equity.  Also, see the capital requirements discussion and table below with respect to our regulatory capital positions.

Capital Requirements

Banner Corporation is a bank holding company registered with the Federal Reserve.  Bank holding companies are subject to capital adequacy requirements of the Federal Reserve under the Bank Holding Company Act of 1956, as amended (BHCA), and the regulations of the Federal Reserve.  Banner Bank and Islanders Bank, as state-chartered, federally insured commercial banks, are subject to the capital requirements established by the FDIC.

The capital adequacy requirements are quantitative measures established by regulation that require Banner Corporation and the Banks to maintain minimum amounts and ratios of capital.  The Federal Reserve requires Banner Corporation to maintain capital adequacy that generally parallels the FDIC requirements.  The FDIC requires the Banks to maintain minimum ratios of Total Capital, Tier 1 Capital, and Common Equity Tier 1 Capital to risk-weighted assets as well as Tier 1 Leverage Capital to average assets.  At March 31, 2015, Banner Corporation and the Banks each exceeded all regulatory capital requirements. (See Item 1, “Business–Regulation,” and Note 18 of the Notes to the Consolidated Financial Statements included in the 2014 Form 10-K for additional information regarding regulatory capital requirements for Banner Corporation and the Banks.)

ITEM 3 – Quantitative and Qualitative Disclosures About Market Risk

Market Risk and Asset/Liability Management

Our financial condition and operations are influenced significantly by general economic conditions, including the absolute level of interest rates as well as changes in interest rates and the slope of the yield curve.  Our profitability is dependent to a large extent on our net interest income, which is the difference between the interest received from our interest-earning assets and the interest expense incurred on our interest-bearing liabilities.

Our activities, like all financial institutions, inherently involve the assumption of interest rate risk.  Interest rate risk is the risk that changes in market interest rates will have an adverse impact on the institution’s earnings and underlying economic value.  Interest rate risk is determined by the maturity and repricing characteristics of an institution’s assets, liabilities and off-balance-sheet contracts.  Interest rate risk is measured by the variability of financial performance and economic value resulting from changes in interest rates.  Interest rate risk is the primary market risk affecting our financial performance.

The greatest source of interest rate risk to us results from the mismatch of maturities or repricing intervals for rate sensitive assets, liabilities and off-balance-sheet contracts.  This mismatch or gap is generally characterized by a substantially shorter maturity structure for interest-bearing liabilities than interest-earning assets, although our floating-rate assets tend to be more immediately responsive to changes in market rates than most funding deposit liabilities.  Additional interest rate risk results from mismatched repricing indices and formula (basis risk and yield curve risk), and product caps and floors and early repayment or withdrawal provisions (option risk), which may be contractual or market driven, that are generally more favorable to customers than to us.  An exception to this generalization is the beneficial effect of interest rate floors on a substantial portion of our performing floating-rate loans, which help us maintain higher loan yields in periods when market interest rates decline significantly.  However, in a declining interest rate environment, as loans with floors are repaid they generally are replaced with new loans which have lower interest rate floors.  As of March 31, 2015, our loans with interest rate floors totaled approximately $1.8 billion and had a weighted average floor rate of 4.8%. An additional source of interest rate risk, which is currently of concern, is a prolonged period of exceptionally low market interest rates. Because interest-bearing deposit costs have been reduced to nominal levels, there is very little possibility that they will be significantly further reduced and our non-interest-bearing deposits are an increasingly significant percentage of total deposits. By contrast, if market rates remain very low, loan and securities yields will likely continue to decline as longer-term instruments mature or are repaid. As a result, a prolonged period of very low interest rates will likely result in further compression of our net interest margin. While this pressure on the margin may be mitigated by further changes in the mix of assets and deposits, particularly increases in non-interest-bearing deposits, a prolonged period of low interest rates will present a very difficult operating environment for most banks, including us.

The principal objectives of asset/liability management are: to evaluate the interest rate risk exposure; to determine the level of risk appropriate given our operating environment, business plan strategies, performance objectives, capital and liquidity constraints, and asset and liability allocation alternatives; and to manage our interest rate risk consistent with regulatory guidelines and policies approved by the Board of Directors.  Through such management, we seek to reduce the vulnerability of our earnings and capital position to changes in the level of interest rates.  Our actions in this regard are taken under the guidance of the Asset/Liability Management Committee, which is comprised of members of our senior management.  The Committee closely monitors our interest sensitivity exposure, asset and liability allocation decisions, liquidity and capital positions, and local and national economic conditions and attempts to structure the loan and investment portfolios and funding sources to maximize earnings within acceptable risk tolerances.

Sensitivity Analysis

Our primary monitoring tool for assessing interest rate risk is asset/liability simulation modeling, which is designed to capture the dynamics of balance sheet, interest rate and spread movements and to quantify variations in net interest income resulting from those movements under different rate environments.  The sensitivity of net interest income to changes in the modeled interest rate environments provides a measurement of interest rate risk.  We also utilize economic value analysis, which addresses changes in estimated net economic value of equity arising from changes in the level of interest rates.  The net economic value of equity is estimated by separately valuing our assets and liabilities under varying interest rate environments.  The extent to which assets gain or lose value in relation to the gains or losses of liability values under the various interest rate assumptions determines the sensitivity of net economic value to changes in interest rates and provides an additional measure of interest rate risk.

The interest rate sensitivity analysis performed by us incorporates beginning-of-the-period rate, balance and maturity data, using various levels of aggregation of that data, as well as certain assumptions concerning the maturity, repricing, amortization and prepayment characteristics of loans and other interest-earning assets and the repricing and withdrawal of deposits and other interest-bearing liabilities into an asset/liability computer simulation model.  We update and prepare simulation modeling at least quarterly for review by senior management and the directors. We believe the data and assumptions are realistic representations of our portfolio and possible outcomes under the various interest rate scenarios.  Nonetheless, the interest rate sensitivity of our net interest income and net economic value of equity could vary substantially if different assumptions were used or if actual experience differs from the assumptions used.

70

The following table sets forth, as of March 31, 2015, the estimated changes in our net interest income over one-year and two-year time horizons and the estimated changes in economic value of equity based on the indicated interest rate environments (dollars in thousands):

⁽¹⁾  Assumes an instantaneous and sustained uniform change in market interest rates at all maturities; however, no rates are allowed to go below zero.  The current federal funds rate is 0.25%.

Another (although less reliable) monitoring tool for assessing interest rate risk is gap analysis.  The matching of the repricing characteristics of assets and liabilities may be analyzed by examining the extent to which assets and liabilities are interest sensitive and by monitoring an institution’s interest sensitivity gap.  An asset or liability is said to be interest sensitive within a specific time period if it will mature or reprice within that time period.  The interest rate sensitivity gap is defined as the difference between the amount of interest-earning assets anticipated, based upon certain assumptions, to mature or reprice within a specific time period and the amount of interest-bearing liabilities anticipated to mature or reprice, based upon certain assumptions, within that same time period.  A gap is considered positive when the amount of interest-sensitive assets exceeds the amount of interest-sensitive liabilities.  A gap is considered negative when the amount of interest-sensitive liabilities exceeds the amount of interest-sensitive assets.  Generally, during a period of rising rates, a negative gap would tend to adversely affect net interest income while a positive gap would tend to result in an increase in net interest income.  During a period of falling interest rates, a negative gap would tend to result in an increase in net interest income while a positive gap would tend to adversely affect net interest income.

Certain shortcomings are inherent in gap analysis.  For example, although certain assets and liabilities may have similar maturities or periods of repricing, they may react in different degrees to changes in market rates.  Also, the interest rates on certain types of assets and liabilities may fluctuate in advance of changes in market rates, while interest rates on other types may lag behind changes in market rates.  Additionally, certain assets, such as ARM loans, have features that restrict changes in interest rates on a short-term basis and over the life of the asset.  Further, in the event of a change in interest rates, prepayment and early withdrawal levels would likely deviate significantly from those assumed in calculating the table.  Finally, the ability of some borrowers to service their debt may decrease in the event of a severe change in market rates.

71

The following table presents our interest sensitivity gap between interest-earning assets and interest-bearing liabilities at March 31, 2015 (dollars in thousands).  The table sets forth the amounts of interest-earning assets and interest-bearing liabilities which are anticipated by us, based upon certain assumptions, to reprice or mature in each of the future periods shown.  At March 31, 2015, total interest-earning assets maturing or repricing within one year exceeded total interest-bearing liabilities maturing or repricing in the same time period by $863 million, representing a one-year cumulative gap to total assets ratio of 16.56%.  Management is aware of the sources of interest rate risk and in its opinion actively monitors and manages it to the extent possible.  The interest rate risk indicators and interest sensitivity gaps as of March 31, 2015 are within our internal policy guidelines and management considers that our current level of interest rate risk is reasonable.

Footnotes for Table of Interest Sensitivity Gap

⁽¹⁾  Adjustable-rate assets are included in the period in which interest rates are next scheduled to adjust rather than in the period in which they are due to mature, and fixed-rate assets are included in the period in which they are scheduled to be repaid based upon scheduled amortization, in each case adjusted to take into account estimated prepayments.  Mortgage loans and other loans are not reduced for allowances for loan losses and non-performing loans.  Mortgage loans, mortgage-backed securities, other loans and investment securities are not adjusted for deferred fees, unamortized acquisition premiums and discounts.

⁽²⁾  Adjustable-rate liabilities are included in the period in which interest rates are next scheduled to adjust rather than in the period they are due to mature.  Although regular savings, demand, interest checking, and money market deposit accounts are subject to immediate withdrawal, based on historical experience management considers a substantial amount of such accounts to be core deposits having significantly longer maturities.  For the purpose of the gap analysis, these accounts have been assigned decay rates to reflect their longer effective maturities.  If all of these accounts had been assumed to be short-term, the one-year cumulative gap of interest-sensitive assets would have been $(255) million, or (4.90)% of total assets at March 31, 2015.  Interest-bearing liabilities for this table exclude certain non-interest-bearing deposits which are included in the average balance calculations in the table contained in Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Comparison of Results of Operations for the Three Months Ended March 31, 2015 and 2014” of this report on Form 10-Q.

ITEM 4 – Controls and Procedures

The management of Banner Corporation is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Securities Exchange Act of 1934 (Exchange Act).  A control procedure, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that its objectives are met.  Also, because of the inherent limitations in all control procedures, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected.  Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures.  The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.  As a result of these inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Further, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

(a) Evaluation of Disclosure Controls and Procedures:  An evaluation of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) was carried out under the supervision and with the participation of our Chief Executive Officer, Chief Financial Officer and several other members of our senior management as of the end of the period covered by this report.  Based on their evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2015, our disclosure controls and procedures were effective in ensuring that the information required to be disclosed by us in the reports it files or submits under the Exchange Act is (i) accumulated and communicated to our management (including the Chief Executive Officer and Chief Financial Officer) in a timely manner, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

(b) Changes in Internal Controls Over Financial Reporting:  In the quarter ended March 31, 2015, there was no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1 – Legal Proceedings

In the normal course of business, we have various legal proceedings and other contingent matters outstanding.  These proceedings and the associated legal claims are often contested and the outcome of individual matters is not always predictable.  These claims and counter claims typically arise during the course of collection efforts on problem loans or with respect to actions to enforce liens on properties in which we hold a security interest.  We are not a party to any pending legal proceedings that management believes would have a material adverse effect on our financial condition or operations.

ITEM 1A – Risk Factors

There have been no material changes in the risk factors previously disclosed in Part 1, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2014 (File No. 0-26584) or otherwise previously disclosed in our Form 10-Q reports filed subsequently.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Accounting

The accompanying unaudited consolidated interim 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 consolidated interim 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 condensed consolidated financial statements, the Company has evaluated events and transactions subsequent to March 31, 2015 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 disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. Certain reclassifications have been made to the 2014 Consolidated Financial Statements and/or schedules to conform to the 2015 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 critical 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 loan and lease losses, (iii) the valuation of financial assets and liabilities recorded at fair value, including other-than-temporary impairment (OTTI) losses, (iv) the valuation of intangibles, such as goodwill, core deposit intangibles and mortgage servicing rights, (v) the valuation of or recognition of deferred tax assets and liabilities, and (vi) the application of acquisition accounting standards to business combinations including purchased credit-impaired loans. 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, 2014 filed with the SEC.  There have been no significant changes in our application of accounting policies during the first three months of 2015.

The information included in this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2014 as filed with the SEC (2014 Form 10-K).  Interim results are not necessarily indicative of results for a full year or any other interim period.

[1] Loans without a specific allowance reserve have not been individually evaluated for impairment, but have been included in pools of homogeneous loans for evaluation of related allowance reserves.

[2] Loans with a specific allowance reserve have been individually evaluated for impairment using either a discounted cash flow analysis or, for collateral dependent loans, current appraisals less costs to sell to establish realizable value. These analyses may identify a specific impairment amount needed or may conclude that no reserve is needed. Any specific impairment that is identified is included in the category’s Related Allowance column.

BASIS OF PRESENTATION AND CRITICAL ACCOUNTING POLICIES

Organization, Consolidation and Presentation of Financial Statements [Abstract]

BASIS OF PRESENTATION AND CRITICAL ACCOUNTING POLICIES

 BASIS OF PRESENTATION AND CRITICAL ACCOUNTING POLICIES

The accompanying unaudited consolidated interim 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 consolidated interim 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 condensed consolidated financial statements, the Company has evaluated events and transactions subsequent to March 31, 2015 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 disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. Certain reclassifications have been made to the 2014 Consolidated Financial Statements and/or schedules to conform to the 2015 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 critical 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 loan and lease losses, (iii) the valuation of financial assets and liabilities recorded at fair value, including other-than-temporary impairment (OTTI) losses, (iv) the valuation of intangibles, such as goodwill, core deposit intangibles and mortgage servicing rights, (v) the valuation of or recognition of deferred tax assets and liabilities, and (vi) the application of acquisition accounting standards to business combinations including purchased credit-impaired loans. 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, 2014 filed with the SEC.  There have been no significant changes in our application of accounting policies during the first three months of 2015.

The information included in this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2014 as filed with the SEC (2014 Form 10-K).  Interim results are not necessarily indicative of results for a full year or any other interim period.

⁽¹⁾  Loans without a specific allowance reserve have not been individually evaluated for impairment, but have been included in pools of homogeneous loans for evaluation of related allowance reserves.

⁽²⁾  Loans with a specific allowance reserve have been individually evaluated for impairment using either a discounted cash flow analysis or, for collateral dependent loans, current appraisals less costs to sell to establish realizable value.  These analyses may identify a specific impairment amount needed or may conclude that no reserve is needed.  Any specific impairment that is identified is included in the category’s Related Allowance column.

⁽¹⁾  Since these loans were already considered classified and/or on nonaccrual status prior to restructuring, the modifications did not have a material effect on the Company’s determination of the allowance for loan losses.

⁽²⁾  The majority of these modifications do not fit into one separate type, such as rate, term, amount, interest-only or payment, but instead are a combination of multiple types of modifications; therefore, they are disclosed in aggregate.

Schedule of Troubled Debt Restructurings Which Incurred A Payment Default

TDRs which incurred a payment default within twelve months of the restructure date during the three-month periods ended March 31, 2015 and 2014.  A default on a TDR results in either a transfer to nonaccrual status or a partial charge-off.

STOCK-BASED COMPENSATION PLANS AND STOCK OPTIONS

 STOCK-BASED COMPENSATION PLANS

The Company operates the following stock-based compensation plans as approved by the shareholders: the 1998 Stock Option Plan, and 2001 Stock Option Plan (collectively the SOPs), the 2012 Restricted Stock and Incentive Bonus Plan, and the 2014 Omnibus Incentive Plan. In addition, the Board approved in 2006 the Long Term Incentive Plan. The purpose of these plans is to promote the success and enhance the value of the Company by providing a means for attracting and retaining highly skilled employees, officers and directors of Banner Corporation and its affiliates and linking their personal interests with those of the Company's shareholders. Under these plans the Company currently has outstanding restricted stock grants, stock options and stock appreciation rights.

Restricted Stock Grants: Under the 2012 Restricted Stock and Incentive Bonus Plan, which was initially approved on April 24, 2012, the Company is authorized to issue up to 300,000 shares of its common stock to provide a means for attracting and retaining highly skilled officers of Banner Corporation and its affiliates. Shares granted under the Plan have a minimum vesting period of three years. The Plan will continue in effect for a term of ten years, after which no further awards may be granted. The 2012 Restricted Stock Plan was amended on April 23, 2013 to provide for the ability to grant (1) cash-denominated incentive-based awards payable in cash or common stock, including those that are eligible to qualify as qualified performance-based compensation for the purposes of Section 162(m) of the Code and (2) restricted stock awards that qualify as qualified performance-based compensation for the purposes of Section 162(m) of the Code. Vesting requirements may include time-based conditions, performance-based conditions, or market-based conditions. As of March 31, 2015, the Company had granted 299,997 shares of restricted stock from the 2012 Restricted Stock and Incentive Bonus Plan, of which 101,541 shares had vested and 198,456 shares remain unvested.

Banner Corporation 2014 Omnibus Incentive Plan: The 2014 Plan was approved by shareholders on April 22, 2014. The 2014 Plan provides for the grant of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units, other stock-based awards and other cash awards, and provides for vesting requirements which may include time-based or performance-based conditions. The Company has reserved 900,000 shares of its common stock for issuance under the 2014 Plan in connection with exercise of awards. As of March 31, 2015, 66,430 shares had been granted under the 2014 Omnibus Plan of which none have vested.

The expense associated with all restricted stock grants was $671,000 and $473,000 for the three-month period ended March 31, 2015 and 2014, respectively. Unrecognized compensation expense for these awards as of March 31, 2015 was $6.9 million and will be amortized over the next 36 months.

Stock Options. Under the SOPs, Banner reserved 2,284,186 shares for issuance pursuant to the exercise of stock options to be granted to directors and employees. Authority to grant additional options under the 1998 Stock Option Plan terminated on July 24, 2008. Authority to grant additional options under the 2001 Stock Option Plan terminated on April 20, 2011. The exercise price of the stock options is set at 100% of the fair market value of the stock price on the date of grant. Options granted vest at a rate of 20% per year from the date of grant and any unexercised incentive stock options will expire ten years after date of grant or 90 days after employment or service ends.

During the three months ended March 31, 2015 and 2014, the Company did not grant any stock options. Additionally, there were no significant modifications made to any stock option grants during the period. The fair values of stock options granted are amortized as compensation expense on a straight-line basis over the vesting period of the grant.

There were no stock-based compensation costs related to the SOPs for the quarters ended March 31, 2015 or March 31, 2014. The SOPs’ stock option grant compensation costs are generally based on the fair value calculated from the Black-Scholes option pricing on the date of the grant award. The Black-Scholes model assumes an expected stock price volatility based on the historical volatility at the date of the grant and an expected term based on the remaining contractual life of the vesting period. The Company bases the estimate of risk-free interest rate on the U.S. Treasury Constant Maturities Indices in effect at the time of the grant. The dividend yield is based on the current quarterly dividend in effect at the time of the grant.

During the three months ended March 31, 2015 and 2014, there were no exercises of stock options. Cash was not used to settle any equity instruments previously granted. The Company issues shares from authorized but unissued shares upon the exercise of stock options. The Company does not currently expect to repurchase shares from any source to satisfy such obligations under the SOPs.

Banner Corporation Long-Term Incentive Plan: In June 2006, the Board of Directors adopted the Banner Corporation Long-Term Incentive Plan effective July 1, 2006. The Plan is an account-based type of benefit, the value of which is directly related to changes in the value of Company common stock, dividends declared on Company common stock and changes in Banner Bank’s average earnings rate, and is considered a stock appreciation right (SAR). Each SAR entitles the holder to receive cash upon vesting, equal to the excess of the fair market value of a share of the Company’s common stock on the date of maturity of the SAR over the fair market value of such share on the date granted. The primary objective of the Plan is to create a retention incentive by allowing officers who remain with the Company or the Banks for a sufficient period of time to share in the increases in the value of Company stock. The Company re-measures the fair value of SARs each reporting period until the award is settled and recognizes changes in fair value and vesting in compensation expense.

The Company recognized a net a net reversal of compensation expense of $105,000 for the three months ended March 31, 2015 due to variations in market value of the underlying stock, compared to compensation expense of $149,000 for the three months ended March 31, 2014. At March 31, 2015, the aggregate liability related to SARs was $44,000 and was included in deferred compensation.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVES AND HEDGING

DERIVATIVES AND HEDGING

The Company, through its Banner Bank subsidiary, is party to various derivative instruments that are used for asset and liability management and customer financing needs. Derivative instruments are contracts between two or more parties that have a notional amount and an underlying variable, require no net investment and allow for the net settlement of positions. The notional amount serves as the basis for the payment provision of the contract and takes the form of units, such as shares or dollars. The underlying variable represents a specified interest rate, index, or other component. The interaction between the notional amount and the underlying variable determines the number of units to be exchanged between the parties and influences the market value of the derivative contract. The Company obtains dealer quotations to value its derivative contracts.

The Company's predominant derivative and hedging activities involve interest rate swaps related to certain term loans and forward sales contracts associated with mortgage banking activities. Generally, these instruments help the Company manage exposure to market risk and meet customer financing needs. Market risk represents the possibility that economic value or net interest income will be adversely affected by fluctuations in external factors such as market-driven interest rates and prices or other economic factors.

Derivatives Designated in Hedge Relationships

The Company's fixed rate loans result in exposure to losses in value or net interest income as interest rates change. The risk management objective for hedging fixed rate loans is to effectively convert the fixed rate received to a floating rate. The Company has hedged exposure to changes in the fair value of certain fixed rate loans through the use of interest rate swaps. For a qualifying fair value hedge, changes in the value of the derivatives are recognized in current period earnings along with the corresponding changes in the fair value of the designated hedged item attributable to the risk being hedged.

In a program brought to Banner Bank through its merger with F&M Bank in 2007, customers received fixed interest rate commercial loans and Banner Bank subsequently hedged that fixed rate loan by entering into an interest rate swap with a dealer counterparty. Banner Bank receives fixed rate payments from the customers on the loans and makes similar fixed rate payments to the dealer counterparty on the swaps in exchange for variable rate payments based on the one-month LIBOR index. Some of these interest rate swaps are designated as fair value hedges. Through application of the “short cut method of accounting,” there is an assumption that the hedges are effective. Banner Bank discontinued originating interest rate swaps under this program in 2008.

As of March 31, 2015 and December 31, 2014, the notional values or contractual amounts and fair values of the Company's derivatives designated in hedge relationships were as follows (in thousands):

	Asset Derivatives								Liability Derivatives

Derivatives Not Designated in Hedge Relationships

Interest Rate Swaps. Banner Bank has been using an interest rate swap program for commercial loan customers, termed the Back-to-Back Program, since 2010. In the Back-to-Back Program, Banner Bank provides the client with a variable rate loan and enters into an interest rate swap in which the client receives a variable rate payment in exchange for a fixed rate payment. Banner Bank offsets its risk exposure by entering into an offsetting interest rate swap with a dealer counterparty for the same notional amount and length of term as the client interest rate swap providing the dealer counterparty with a fixed rate payment in exchange for a variable rate payment. There are also a few interest rate swaps from prior to 2009 that were not designated in hedge relationships that are included in these totals. These swaps do not qualify as designated hedges; therefore, each swap is accounted for as a free standing derivative.

Mortgage Banking. In the normal course of business, the Company sells originated mortgage loans into the secondary mortgage loan markets. During the period of loan origination and prior to the sale of the loans in the secondary market, the Company has exposure to movements in interest rates associated with written rate lock commitments with potential borrowers to originate loans that are intended to be sold and for closed loans that are awaiting sale and delivery into the secondary market.

Written loan commitments that relate to the origination of mortgage loans that will be held for resale are considered free-standing derivatives and do not qualify for hedge accounting. Written loan commitments generally have a term of up to 60 days before the closing of the loan. The loan commitment does not bind the potential borrower to enter into the loan, nor does it guarantee that the Company will approve the potential borrower for the loan. Therefore, when determining fair value, the Company makes estimates of expected “fallout” (loan commitments not expected to close), using models which consider cumulative historical fallout rates, current market interest rates and other factors.

Written loan commitments in which the borrower has locked in an interest rate results in market risk to the Company to the extent market interest rates change from the rate quoted to the borrower. The Company economically hedges the risk of changing interest rates associated with its interest rate lock commitments by entering into forward sales contracts.

Mortgage loans which are held for sale are subject to changes in fair value due to fluctuations in interest rates from the loan's closing date through the date of sale of the loans into the secondary market. Typically, the fair value of these loans declines when interest rates increase and rises when interest rates decrease. To mitigate this risk, the Company enters into forward sales contracts on a significant portion of these loans to provide an economic hedge against those changes in fair value. Mortgage loans held for sale and the forward sales contracts are recorded at fair value with changes in value recorded in current earnings within mortgage banking operations.

As of March 31, 2015 and December 31, 2014, the notional values or contractual amounts and fair values of the Company's derivatives not designated in hedge relationships were as follows (in thousands):

Gains (losses) recognized in income on non-designated hedging instruments for the three months ended March 31, 2015 and 2014 were as follows (in thousands):

The Company is exposed to credit-related losses in the event of nonperformance by the counterparty to these agreements. Credit risk of the financial contract is controlled through the credit approval, limits, and monitoring procedures and management does not expect the counterparties to fail their obligations.

In connection with the interest rate swaps between Banner Bank and the dealer counterparties, the agreements contain a provision where if Banner Bank fails to maintain its status as a well/adequately capitalized institution, then the counterparty could terminate the derivative positions and Banner Bank would be required to settle its obligations. Similarly, Banner Bank could be required to settle its obligations under certain of its agreements if specific regulatory events occur, such as a publicly issued prompt corrective action directive, cease and desist order, or a capital maintenance agreement that required Banner Bank to maintain a specific capital level. If Banner Bank had breached any of these provisions at March 31, 2015 or December 31, 2014, it could have been required to settle its obligations under the agreements at the termination value. As of March 31, 2015 and December 31, 2014, the termination value of derivatives in a net liability position related to these agreements was $8.8 million and $6.3 million, respectively. The Company generally posts collateral against derivative liabilities in the form of government agency-issued bonds, mortgage-backed securities, or commercial mortgage-backed securities. Collateral posted against derivative liabilities was $13.4 million and $11.1 million as of March 31, 2015 and December 31, 2014, respectively.

Derivative assets and liabilities are recorded at fair value on the balance sheet and do not take into account the effects of master netting agreements. Master netting agreements allow the Company to settle all derivative contracts held with a single counterparty on a net basis and to offset net derivative positions with related collateral where applicable.

INTANGIBLE ASSETS AND MORTGAGE SERVICING RIGHTS

INTANGIBLE ASSETS AND MORTGAGE SERVICING RIGHTS

Goodwill and Other Intangible Assets:  At March 31, 2015, intangible assets are comprised of goodwill and core deposit intangibles (CDI) acquired in business combinations. Goodwill represents the excess of the total purchase price paid over the fair value of the assets acquired, net of the fair values of liabilities assumed, and is not amortized but is reviewed annually for impairment. Additions to goodwill during 2015 relate to the Siuslaw acquisition. See Note 4, Business Combinations, for additional information on the acquisition and purchase price allocation.

The Company amortizes CDI over their estimated useful lives and reviews them at least annually for events or circumstances that could impair their value.  The CDI assets shown in the table below represent the value ascribed to the long-term deposit relationships acquired in three separate bank acquisitions during 2007, a single branch acquisition in 2013, the Branch Acquisition in 2014 and the acquisition of Siuslaw in 2015.  These intangible assets are being amortized using an accelerated method over estimated useful lives of three to eight years.  The CDI assets are not estimated to have a significant residual value.

The following table summarizes the changes in the Company’s goodwill and other intangibles for the three months ended March 31, 2015 and the year ended December 31, 2014 (in thousands):

	Goodwill		CDI			Total
Balance, December 31, 2013	$	—	$	2,449		$	2,449
Additions through acquisitions	—		2,372			2,372

Balance, December 31, 2014	—		2,831			2,831
Additions through acquisitions	21,148		3,895			25,043
Amortization	—		(616		)	(616		)
Balance, March 31, 2015	$	21,148	$	6,110		$	27,258

The following table presents the estimated amortization expense with respect to intangibles for the periods indicated (in thousands):

	CDI
Remainder of 2015	$	910
2016	944
2017	872
2018	809
2019	746
Thereafter	1,829
	$	6,110

Mortgage Servicing Rights:  Mortgage servicing rights are reported in other assets. Mortgage servicing rights are initially recorded at fair value and are amortized in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets.  Mortgage servicing rights are subsequently evaluated for impairment based upon the fair value of the rights compared to the amortized cost (remaining unamortized initial fair value).  If the fair value is less than the amortized cost, a valuation allowance is created through an impairment charge, which is recognized in servicing fee income on the consolidated statement of operations.   However, if the fair value is greater than the amortized cost, the amount above the amortized cost is not recognized in the carrying value.  Loans serviced for others totaled $2.096 billion and $1.391 billion at March 31, 2015 and December 31, 2014, respectively.  Custodial accounts maintained in connection with this servicing totaled $8.0 million and $6.7 million at March 31, 2015 and December 31, 2014, respectively.

An analysis of our mortgage servicing rights, net of valuation allowances, for the three months ended March 31, 2015 and 2014 is presented below (in thousands):

	Three Months Ended March 31
	2015			2014
Balance, beginning of the period	$	9,030		$	8,086
Additions-amounts capitalized	1,216			575
Additions-acquired through business combinations	2,172			—
Amortization (1)	(709		)	(462		)
Balance, end of the period (2)	$	11,709		$	8,199

⁽¹⁾  Amortization of mortgage servicing rights is recorded as a reduction of loan servicing income and any unamortized balance is fully written off if the loan repays in full.

⁽²⁾  There was no valuation allowance as of March 31, 2015 and 2014.

BUSINESS COMBINATIONS

Acquisition of Siuslaw Financial Group, Inc.

Effective as of the close of business on March 6, 2015, the Company completed the purchase of Siuslaw, the holding company of Siuslaw Bank. Siuslaw merged with and into the Company and, immediately following, Siuslaw Bank merged with and into Banner Bank. Siuslaw shareholders received 0.32231 shares of the Company's common stock and $1.41622 in cash in exchange for each share of Siuslaw common stock. The Company acquired 100% of Siuslaw's voting equity interests in the transaction. The acquisition provided $370 million in assets, $316 million in deposits and $247 million in loans.

The assets acquired and liabilities assumed in the purchase have been accounted for under the acquisition method of accounting and, accordingly, the assets and liabilities, both tangible and intangible, were recorded at their estimated fair value as of the acquisition date. The application of the acquisition method of accounting resulted in recognition of a core deposit intangible asset of $3.9 million and goodwill of $21.1 million. The acquired core deposit intangible has been determined to have a useful life of approximately eight years and will be amortized on an accelerated basis. Goodwill is not amortized but will be evaluated for impairment on an annual basis or more often if circumstances dictate to determine if the carrying value remains appropriate. Goodwill will not be deductible for income tax purposes as the acquisition is accounted for as a tax-free exchange for tax purposes.

The following table presents a summary of the consideration paid and the estimated fair values as of the acquisition date for each major class of assets acquired and liabilities assumed (in thousands):

	Siuslaw
	March 6, 2015
Consideration to Siuslaw shareholders:
Cash paid			$	5,806
Fair value of common shares issued			58,100
Total consideration			63,906
Fair value of assets acquired:
Cash and cash equivalents	$	84,405
Securities—available-for-sale	12,865
Loans receivable (contractual amount of $252.2 million)	247,098
Real estate owned, held for sale	2,525
Property and equipment	8,127
Core deposit intangible	3,895
Other assets	11,391
Total assets acquired	370,306
Fair value of liabilities assumed:
Deposits	316,406
Junior subordinated debentures	5,959
Other liabilities	5,183
Total liabilities assumed	327,548
Net assets acquired			42,758
Goodwill			$	21,148

Acquired goodwill represents the premium the Company paid over the fair value of the net tangible and intangible assets acquired. The Company paid this premium for a number of reasons, including growing the Company's customer base, acquiring assembled workforces, and expanding its presence in new markets. See Note 9, Goodwill and Other Intangible Assets for the accounting for goodwill and other intangible assets.

Amounts recorded are preliminary estimates of fair value. Additional adjustments to the purchase price allocation may be required and would most likely involve loans or property and equipment. The primary reason for the acquisition was to continue the Company's growth strategy, including expanding our geographic footprint in markets throughout the Northwest. As of March 6, 2015, the unpaid principal balance on purchased non-credit-impaired loans was $244.2 million. The fair value of the purchased non-credit-impaired loans was $241.4 million, resulting in a discount of $2.8 million recorded on these loans.

The following table presents the acquired purchased credit-impaired loans as of the acquisition date (in thousands):

	Siuslaw
	March 6, 2015
Acquired purchased credit-impaired loans:
Contractually required principal and interest payments	$	11,134
Nonaccretable difference	(3,238		)
Cash flows expected to be collected	7,896
Accretable yield	(2,239		)
Fair value of purchased credit-impaired loans	$	5,657

The following table presents certain unaudited pro forma information for illustrative purposes only, for the three months ended March 31, 2015 and 2014 as if Siuslaw had been acquired on January 1, 2014. This unaudited estimated pro forma financial information combines the historical results of Siuslaw with the Company’s consolidated historical results. The pro forma information is not indicative of what would have occurred had the acquisition occurred on January 1, 2014. In particular, no adjustments have been made to eliminate the impact of other-than-temporary impairment losses and losses recognized on the sale of securities that may not have been necessary had the investment securities been recorded at fair value as of January 1, 2014. The unaudited pro forma information does not consider any changes to the provision for credit losses resulting from recording loan assets at fair value. Additionally, Banner expects to achieve further operating cost savings and other business synergies, including revenue growth, as a result of the acquisition which are not reflected in the pro forma amounts that follow. As a result, actual amounts would have differed from the unaudited pro forma information presented. (in thousands except per share).

	Pro Forma
	Three Months Ended March 31,
	2015		2014
Total revenues (net interest income plus non-interest income	$	63,164	$	55,829
Net income	$	12,518	$	11,413
Earnings per share - basic	$	0.59	$	0.55
Earnings per share - diluted	$	0.59	$	0.55

The operating results of the Company include the operating results produced by the acquired assets and assumed liabilities of Siuslaw for the period March 7, 2015 to March 31, 2015. Disclosure of the amount of Siuslaw’s revenue and net income (excluding integration costs) included in the Company’s consolidated income statement is impracticable due to the integration of the operations and accounting for this acquisition.

Acquisition of Six Oregon Branches

Effective as of the close of business on June 20, 2014, Banner Bank completed the purchase of six branches from Umpqua Bank, successor to Sterling Savings Bank (the Branch Acquisition). Five of the six branches are located in Coos County, Oregon and the sixth branch is located in Douglas County, Oregon. The purchase provided $212 million in deposit accounts, $88 million in loans, and $3 million in branch properties. Banner Bank received $128 million in cash from the transaction.

The assets acquired and liabilities assumed in the purchase have been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the acquisition date. The application of the acquisition method of accounting resulted in recognition of a core deposit intangible asset of $2.4 million and an acquisition bargain purchase gain of $9.1 million. The bargain purchase gain represents the excess fair value of the net assets acquired over the purchase price, including fair value of liabilities assumed. The bargain purchase gain consisted primarily of a $7.0 million discount on the assets acquired in this required branch divestiture combined with a $2.4 million core deposit intangible, net of approximately $300,000 in other fair value adjustments. The acquired core deposit intangible was determined to have a useful life of approximately eight years and is being amortized on an accelerated basis.

The following table displays the fair value as of the acquisition date for each major class of assets acquired and liabilities assumed (in thousands):

	Branch Acquisition
	June 20, 2014
Total consideration			$	—
Fair value of assets acquired:

Deposits	212,085
Other liabilities	42
Total liabilities assumed	212,127
Net assets acquired			$	9,079

The primary reason for the acquisition was to continue the Company's growth strategy, including expanding its geographic footprint in markets throughout the Northwest. As of June 20, 2014, the transaction had no remaining contingencies. The operating results of the Company include the operating results produced by the Branch Acquisition from June 21, 2014 to March 31, 2015. Pro forma results of operations for the three months ended March 31, 2015 and 2014, as if the Branch Acquisition had occurred on January 1, 2014, have not been presented because historical financial information was not available. There were not any purchased credit-impaired loans acquired in connection with the Branch Acquisition.

Accounting Changes and Error Corrections [Abstract]

ACCOUNTING STANDARDS RECENTLY ISSUED OR ADOPTED

 ACCOUNTING STANDARDS RECENTLY ISSUED OR ADOPTED

Investing in Qualified Affordable Housing Projects

In January 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. The objective of this ASU is to provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit. The amendments in this ASU modify the conditions that a reporting entity must meet to be eligible to use a method other than the equity or cost methods to account for qualified affordable housing project investments. If the modified conditions are met, the amendments permit an entity to amortize the initial cost of the investment in proportion to the amount of tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense (benefit). Additionally, the amendments introduce new recurring disclosures about all investments in qualified affordable housing projects irrespective of the method used to account for the investments. The amendments in this ASU have been applied retrospectively to all periods presented. ASU No. 2014-01 is effective beginning after December 15, 2014 and did not have a material impact on the Company's consolidated financial statements.

Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure

In January 2014, FASB issued ASU No. 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The amendments in this ASU clarify that an in-substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU No. 2014-04 is effective for fiscal years and interim periods beginning after December 15, 2014 and did not have a material impact on the Company's consolidated financial statements.

Revenue from Contracts with Customers

In May 2014, FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which creates Topic 606 and supersedes Topic 605, Revenue Recognition. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The standard is effective for public entities for interim and annual periods beginning after December 15, 2016 although FASB issued a proposed ASU on April 29, 2015 that would defer the effective date by one year (i.e. to reporting periods beginning after December 15, 2017); early adoption is not permitted. For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company is currently evaluating the provisions of ASU No. 2014-09 to determine the potential impact the standard will have on the Company’s consolidated financial statements.

Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure

In August 2014, FASB issued ASU No. 2014-14, Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure. The amendments in this ASU affect creditors that hold government-guaranteed mortgage loans, including those guaranteed by the FHA and the VA. The ASU provides specific guidance on how to classify or measure foreclosed mortgage loans that are government guaranteed. The amendments in this Update require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: 1) the loan has a government guarantee that is not separable from the loan before foreclosure, 2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and creditor has the ability to recover under the claim and, 3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. ASU No. 2014-14 is effective for fiscal years and interim periods beginning after December 15, 2014 and did not have a material impact on the Company's consolidated financial statements.

Income Statement - Extraordinary and Unusual Items (Subtopic 225-20)

In January 2015, FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20). The ASU eliminated from GAAP the concept of extraordinary items. Under subtopic 225-20, entities were required to separately classify, present, and disclose extraordinary events and transactions that were both unusual in nature and infrequent in occurrence. This amendment will save time and reduce costs for preparers, as well as alleviate uncertainty for auditors and regulators in evaluating potentially extraordinary items. The amendment is effective for fiscal years and interim reporting periods after December 15, 2015. It may be applied prospectively, and retrospectively to all reporting periods presented in the financial statements. The adoption of ASU No. 2015-01 did not have a material impact on the Company's consolidated financial statements.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES

Lease Commitments — The Company leases 66 sites under non-cancelable operating leases. The leases contain various provisions for increases in rental rates, based either on changes in the published Consumer Price Index or a predetermined escalation schedule. Substantially all of the leases provide the Company with the option to extend the lease term one or more times following expiration of the initial term.

Financial Instruments with Off-Balance-Sheet Risk — The Company has financial instruments with off-balance-sheet risk generated in the normal course of business to meet the financing needs of our customers.  These financial instruments include commitments to extend credit, commitments related to standby letters of credit, commitments to originate loans, commitments to sell loans, commitments to buy and sell securities.  These instruments involve, to varying degrees, elements of credit and interest rate risk similar to the risk involved in on-balance sheet items recognized in our Consolidated Statements of Financial Condition.

Our exposure to credit loss in the event of nonperformance by the other party to the financial instrument from commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments.  We use the same credit policies in making commitments and conditional obligations as for on-balance-sheet instruments.

Outstanding commitments for which no asset or liability for the notional amount has been recorded consisted of the following at the dates indicated (in thousands):

	Contract or Notional Amount
	March 31, 2015		December 31, 2014
Commitments to extend credit	$	1,275,871	$	1,166,165
Standby letters of credit and financial guarantees	10,584		9,934
Commitments to originate loans	41,880		20,988
Derivatives also included in Note 16:
Commitments to originate loans held for sale	62,093		29,851
Commitments to sell loans secured by one- to four-family residential properties	21,040		8,714
Commitments to sell securities related to mortgage banking activities	43,572		25,000

Commitments to extend credit are agreements to lend to a customer, as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Many of the commitments may expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case-by-case basis.  The amount of collateral obtained, if deemed necessary upon extension of credit, is based on management’s credit evaluation of the customer. The type of collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, and income producing commercial properties.

Standby letters of credit are conditional commitments issued to guarantee a customer’s performance or payment to a third party.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Interest rates on residential one- to four-family mortgage loan applications are typically rate locked (committed) to customers during the application stage for periods ranging from 30 to 60 days, the most typical period being 45 days. Traditionally these loan applications with rate lock commitments had the pricing for the sale of these loans locked with various qualified investors under a best-efforts delivery program at or near the time the interest rate is locked with the customer. The Company then attempts to deliver these loans before their rate locks expired. This arrangement generally required delivery of the loans prior to the expiration of the rate lock. Delays in funding the loans required a lock extension. The cost of a lock extension at times was borne by the customer and at times by the Bank. These lock extension costs have not had a material impact to our operations. In 2012, the Company also began entering into forward commitments at specific prices and settlement dates to deliver either: (1) residential mortgage loans for purchase by secondary market investors (i.e., Freddie Mac or Fannie Mae), or (2) mortgage-backed securities to broker/dealers. The purpose of these forward commitments is to offset the movement in interest rates between the execution of its residential mortgage rate lock commitments with borrowers and the sale of those loans to the secondary market investor. There were nocounterparty default losses on forward contracts in the three months ended March 31, 2015 or March 31, 2014. Market risk with respect to forward contracts arises principally from changes in the value of contractual positions due to changes in interest rates. We limit our exposure to market risk by monitoring differences between commitments to customers and forward contracts with market investors and securities broker/dealers. In the event we have forward delivery contract commitments in excess of available mortgage loans, the transaction is completed by either paying or receiving a fee to or from the investor or broker/dealer equal to the increase or decrease in the market value of the forward contract.

Legal Proceedings — In the normal course of business, the Company and/or its subsidiaries have various legal proceedings and other contingent matters outstanding. These proceedings and the associated legal claims are often contested and the outcome of individual matters is not always predictable. The claims and counter-claims typically arise during the course of collection efforts on problem loans or with respect to action to enforce liens on properties in which the Company holds a security interest. Based on information known to management at this time, the Company is not a party to any legal proceedings that management believes would have a material adverse effect on the Company's results of operations or consolidated financial position at March 31, 2015.

FAIR VALUE ACCOUNTING AND MEASUREMENT

Fair Value Disclosures [Abstract]

FAIR VALUE ACCOUNTING AND MEASUREMENT

FAIR VALUE ACCOUNTING AND MEASUREMENT

The Company measures and discloses certain assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (that is, not a forced liquidation or distressed sale). GAAP (ASC 820, Fair Value Measurements) establishes a consistent framework for measuring fair value and disclosure requirements about fair value measurements. Among other things, the accounting standard requires the reporting entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s estimates for market assumptions. These two types of inputs create the following fair value hierarchy:

• Level 1 – Quoted prices in active markets for identical instruments. An active market is a market in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available.

• Level 2 – Observable inputs other than Level 1 including quoted prices in active markets for similar instruments, quoted prices in less active markets for identical or similar instruments, or other observable inputs that can be corroborated by observable market data.

• Level 3 – Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation; also includes observable inputs from non-binding single dealer quotes not corroborated by observable market data.

The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize at a future date. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for certain financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values. Transfers between levels of the fair value hierarchy are deemed to occur at the end of the reporting period.

Items Measured at Fair Value on a Recurring Basis:

Banner records trading account securities, securities available-for-sale, FHLB advances, junior subordinated debentures and certain derivative transactions at fair value on a recurring basis.

• Investment securities primarily consist of U.S. Government and agency obligations, municipal bonds, corporate bonds, single issue trust preferred securities (TPS), pooled trust preferred collateralized debt obligation securities (TRUP CDO), mortgage-backed securities, asset-backed securities, equity securities and certain other financial instruments.

From mid-2008 through the current quarter, the lack of active markets and market participants for certain securities resulted in an increase in Level 3 measurements. In particular, the market for our TRUP CDO securities has been generally inactive during this period. This was evidenced first by a significant widening of the bid-ask spread in the brokered markets in which TRUP CDOs trade and then by a significant decrease in the volume of trades relative to historical levels. The new issue market also has been inactive as almost no new TRUP CDOs have been issued since 2007. There are still very few market participants who are willing and/or able to transact for these securities. Thus, a low market price for a particular bond may only provide evidence of stress in the credit markets in general rather than being an indicator of credit problems with a particular issuer or of the fair value of the security. As of March 31, 2015, Banner owned $6 million in par value of these securities.

Given these conditions in the debt markets and the absence of observable transactions in the secondary and new issue markets, management determined that for the TRUP CDOs at March 31, 2015 and December 31, 2014:

• The few observable transactions and market quotations that were available were not reliable for purposes of determining fair value,

• An income valuation approach technique (present value technique) that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs was equally or more representative of fair value than the market approach valuation technique, and

• The Company’s TRUP CDOs should be classified exclusively within Level 3 of the fair value hierarchy because of the significant assumptions required to determine fair value at the measurement date.

The TRUP CDO valuations were derived using input from independent third parties who used proprietary cash flow models for analyzing collateralized debt obligations. Their approaches to determining fair value involve considering the credit quality of the collateral, assuming a level of defaults based on the probability of default of each underlying trust preferred security, creating expected cash flows for each TRUP CDO security and discounting that cash flow at an appropriate risk-adjusted rate plus a liquidity premium.

Where appropriate, management reviewed the valuation methodologies and assumptions used by the independent third party providers and determined that the fair value estimates were reasonable and utilized those estimates in the Company’s reported financial statements. One TRUP CDO security was sold in the first quarter 2015 at a price significantly less than par, but more than our carrying value. For that security we received $2.2 million against an unamortized cost of $2.9 million and a carrying value of $1.7 million. A book loss was recognized in the amount of $642,000 but an offsetting reversal of a fair value allowance was also recorded as a gain of $1.2 million, resulting in a net gain for this security of $555,000 in the current quarter. Another TRUP CDO security was partially redeemed in the amount of $109,000 against a carrying value of zero, resulting in a reversal of a valuation allowance of $109,000. The aggregate result of the fair value analysis of all the Level 3 TRUP CDO measurements was a fair value gain of $1.4 million in the quarter ended March 31, 2015.

At March 31, 2015, Banner also owned approximately $19 million in amortized cost of single issuer TPS securities for which no direct market data or independent valuation source is available. Similar to the TRUP CDOs above, there were too few, if any, issuances of new TPS securities or sales of existing TPS securities to provide Level 1 or even Level 2 fair value measurements for these securities. Management, therefore, utilized a discounted cash-flow model to calculate the present value of each security’s expected future cash flows to determine their respective fair values. Management took into consideration the limited market data that was available regarding similar securities and assessed the performance of the three individual issuers of TPS securities owned by the Company. In the current quarter, the Company again sought input from independent third parties to help it establish an appropriate set of parameters to identify a reasonable range of discount rates for use in its fair value model. Management concluded that market yields have been relatively stable in the quarter ended March 31, 2015 and that the indicated spreads and implied yields for non-investment grade securities as well as the yields associated with individual issuers in the third party analyst reports continue to support that a 500 basis point spread over the three-month LIBOR index, the same spread as used in the quarter ended December 31, 2014, was still a reasonable basis for determining an appropriate discount rate to estimate the fair value of these securities. These factors were then incorporated into the model at March 31, 2015, where a discount rate equal to three-month LIBOR plus 500 basis points was used to calculate the respective fair values of these securities. The result of this Level 3 fair value measurement was a fair value gain of $43,000 in the quarter ended March 31, 2015. The Company has and will continue to assess the appropriate fair value hierarchy for determination of fair values on TRUP CDO and TPS securities on a quarterly basis. For all other trading securities and securities available-for-sale we used matrix pricing models from investment reporting and valuation services. Management considers this to be a Level 2 input method.

• Fair valuations for FHLB advances are estimated using fair market values provided by the lender, the FHLB of Seattle. The FHLB of Seattle prices advances by discounting the future contractual cash flows for individual advances using its current cost of funds curve to provide the discount rate. Management considers this to be a Level 2 input method.

• The fair valuations of junior subordinated debentures (TPS-related debt that the Company has issued or acquired in the Siuslaw merger) were also valued using discounted cash flows. These debentures carry interest rates that reset quarterly, using the three-month LIBOR index plus spreads of 1.38% to 3.35%.  While the quarterly reset of the index on this debt would seemingly keep its fair value reasonably close to book value, the disparity in the fixed spreads above the index and the inability to determine realistic current market spreads, due to lack of new issuances and trades, resulted in having to rely more heavily on assumptions about what spread would be appropriate if market transactions were to take place. In periods prior to the third quarter of 2008, the discount rate used was based on recent issuances or quotes from brokers on the date of valuation for comparable bank holding companies and was considered to be a Level 2 input method. However, as noted above in the discussions of TPS and TRUP CDOs, due to the unprecedented disruption of certain financial markets, management concluded that there were insufficient transactions or other indicators to continue to reflect these measurements as Level 2 inputs.  Due to this reliance on assumptions and not on directly observable transactions, management believes fair value for these instruments should follow a Level 3 input methodology. Since the discount rate used in the fair value modeling is the most sensitive unobservable estimate in the calculation, the Company again utilized input from the same independent third party noted above to help it establish an appropriate set of parameters to identify a reasonable range of discount rates for use in its fair value model. In valuing the debentures at March 31, 2015, management evaluated the general market for credit spreads as noted above and for the discount rate used the period-ending three-month LIBOR plus 500 basis points. As noted above in the discussion about single-issuer TPS securities, since market spreads have been relatively stable in the recent period we used the same spread as used in the quarter ended December 31, 2014, resulting in a fair value loss on these instruments of $366,000 for the quarter ended March 31, 2015. The fair value adjustment in the current period was attributed to the passage of time on the years to maturity in the discounted present value calculation used to estimate the fair value.

• Derivative instruments include interest rate commitments related to one- to four-family loans and residential mortgage-backed securities and interest rate swaps.  The fair value of interest rate lock commitments and forward sales commitments are estimated using quoted or published market prices for similar instruments, adjusted for factors such as pull-through rate assumptions based on historical trends, where appropriate.  The fair value of interest rate swaps is determined by using current market quotes on similar instruments provided by active broker/dealers in the swap market.  Management considers these to be Level 2 input methods. The changes in the fair value of all of these derivative instruments are primarily attributable to changes in the level of market interest rates.  The Company has elected to record the fair value of these derivative instruments on a net basis.

The Company has elected to continue to recognize the interest income and dividends from the securities reclassified to fair value as a component of interest income as was done in prior years when they were classified as available-for-sale.  Interest expense related to the FHLB advances and junior subordinated debentures continues to be measured based on contractual interest rates and reported in interest expense.  The change in fair market value of these financial instruments has been recorded as a component of other operating income.

Items Measured at Fair Value on a Non-recurring Basis:

Impaired loans are periodically evaluated to determine if valuation adjustments, or partial write-downs, should be recorded. The need for valuation adjustments arises when observable market prices or current appraised values of collateral indicate a shortfall in collateral value or discounted cash flows indicate a shortfall compared to current carrying values of the related loan. If the Company determines that the value of the impaired loan is less than the carrying value of the loan, the Company either establishes an impairment reserve as a specific component of the allowance for loan and lease losses (ALLL) or charges off the impaired amount. These valuation adjustments are considered non-recurring fair value adjustments. The remaining impaired loans are evaluated for reserve needs in homogenous pools within the Company’s ALLL methodology. As of March 31, 2015, the Company reviewed all of its adversely classified loans totaling $80 million and identified $52 million which were considered impaired. Of those $52 million in impaired loans, $40 million were individually evaluated to determine if valuation adjustments, or partial write-downs, should be recorded, or if specific impairment reserves should be established. The $40 million had original carrying values of $43 million which have been reduced by partial write-downs totaling $3 million. In addition to these write-downs, in order to bring the impaired loan balances to fair value, Banner has also established $3 million in specific reserves on these impaired loans. Impaired loans that were collectively evaluated for reserve purposes within homogenous pools totaled $12 million and were found to require allowances totaling $229,000. The valuation inputs for impaired loans are considered to be Level 3 inputs.

The Company records REO (acquired through a lending relationship) at fair value on a non-recurring basis. All REO properties are recorded at the lower of the estimated fair value of the properties, less expected selling costs, or the carrying amount of the defaulted loans. From time to time, non-recurring fair value adjustments to REO are recorded to reflect partial write-downs based on an observable market price or current appraised value of property. Banner considers any valuation inputs related to REO to be Level 3 inputs. The individual carrying values of these assets are reviewed for impairment at least annually and any additional impairment charges are expensed to operations. For the three months ended March 31, 2015, the Company recognized no impairment charges related to REO assets, compared to $37,000 for the same quarter one year earlier.

The following tables present financial assets measured at fair value on a non-recurring basis and the level within the fair value hierarchy of the fair value measurements for those assets as of March 31, 2015 and December 31, 2014 (in thousands):

Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs (Level 3):

The following table provides a description of the valuation technique, unobservable inputs, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring and nonrecurring basis at March 31, 2015 and December 31, 2014:

			Weighted Average Rate
Financial Instruments	Valuation Techniques	Unobservable Inputs	March 31, 2015		December 31, 2014
TPS securities	Discounted cash flows	Discount rate	5.27	%	5.26	%
TRUP CDOs	Discounted cash flows	Discount rate	4.02		3.96
Junior subordinated debentures	Discounted cash flows	Discount rate	5.27		5.26
Impaired loans	Collateral Valuations	Market values	n/a		n/a
REO	Appraisals	Market values	n/a		n/a

TPS and TRUP CDOs: Management believes that the credit risk-adjusted spread used to develop the discount rate utilized in the fair value measurement of TPS and TRUP CDOs is indicative of the risk premium a willing market participant would require under current market conditions for instruments with similar contractual rates and terms and conditions and issuers with similar credit risk profiles and with similar expected probability of default. Management attributes the change in fair value of these instruments, compared to their par value, primarily to perceived general market adjustments to the risk premiums for these types of assets subsequent to their issuance.

Junior subordinated debentures: Similar to the TPS and TRUP CDOs discussed above, management believes that the credit risk-adjusted spread utilized in the fair value measurement of the junior subordinated debentures is indicative of the risk premium a willing market participant would require under current market conditions for an issuer with Banner's credit risk profile. Management attributes the change in fair value of the junior subordinated debentures, compared to their par value, primarily to perceived general market adjustments to the risk premiums for these types of liabilities subsequent to their issuance. Future contractions in the risk adjusted spread relative to the spread currently utilized to measure the Company's junior subordinated debentures at fair value as of March 31, 2015, or the passage of time, will result in negative fair value adjustments. At March 31, 2015, the discount rate utilized was based on a credit spread of 500 basis points and three-month LIBOR of 27 basis points.

Impaired loans: Loans are considered impaired when, based on current information and events, management determines that it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Factors involved in determining impairment include, but are not limited to, the financial condition of the borrower, the value of the underlying collateral and the current status of the economy. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of collateral if the loan is collateral dependent. If this practical expedient is used, the impaired loans are considered to be held at fair value. Subsequent changes in the value of impaired loans are included within the provision for loan losses in the same manner in which impairment initially was recognized or as a reduction in the provision that would otherwise be reported.

REO: Fair value adjustments on REO are based on updated real estate appraisals which are based on current market conditions.

Fair Values of Financial Instruments:

The following table presents estimated fair values of the Company’s financial instruments as of March 31, 2015 and December 31, 2014, whether or not measured at fair value in the consolidated Statements of Financial Condition.  The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies.  However, considerable judgment is necessary to interpret market data in the development of the estimates of fair value.  Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange.  The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.  The carrying value and estimated fair value of financial instruments are as follows (in thousands):

Fair value estimates, methods, assumptions and the level within the fair value hierarchy of the fair value measurements are set forth below for the Company’s financial and off-balance-sheet instruments:

Cash and Due from Banks:  The carrying amount of these items is a reasonable estimate of their fair value. These values are considered Level 1 measures.

Securities:  The estimated fair values of investment securities and mortgaged-backed securities are priced using current active market quotes, if available, which are considered Level 1 measurements.  For most of the portfolio, matrix pricing based on the securities’ relationship to other benchmark quoted prices is used to establish the fair value.  These measurements are considered Level 2.  Due to the continued credit concerns in the capital markets and inactivity in the trust preferred markets that have limited the observability of market spreads for some of the Company’s TPS and TRUP CDO securities (see earlier discussion above in determining the securities’ fair market value), management has classified these securities as a Level 3 fair value measure.

Loans Receivable:  Fair values are estimated first by stratifying the portfolios of loans with similar financial characteristics.  Loans are segregated by type such as multifamily real estate, residential mortgage, nonresidential mortgage, commercial/agricultural, consumer and other.  Each loan category is further segmented into fixed- and adjustable-rate interest terms and by performing and non-performing categories.  A preliminary estimate of fair value is then calculated based on discounted cash flows using as a discount rate the current rate offered on similar products, plus an adjustment for liquidity to reflect the non-homogeneous nature of the loans.  The preliminary estimate is then further reduced by the amount of the allowance for loan losses to arrive at a final estimate of fair value.  Fair value for significant non-performing loans is also based on recent appraisals or estimated cash flows discounted using rates commensurate with risk associated with the estimated cash flows.  Assumptions regarding credit risk, cash flows and discount rates are judgmentally determined using available market information and specific borrower information.  Management considers this to be a Level 2 measure.

FHLB Stock:  The fair value is based upon the redemption value of the stock which equates to its carrying value.  This fair value is considered a Level 3 measure.

Mortgage Servicing Rights:  Fair values are estimated based on current pricing for sales of servicing for new loans adjusted up or down based on the serviced loan’s interest rate versus current new loan rates.  Management considers this to be a Level 3 measure.

Deposit Liabilities:The fair value of deposits with no stated maturity, such as savings and checking accounts, is estimated by applying decay rate assumptions to segregated portfolios of similar deposit types to generate cash flows which are then discounted using short-term market interest rates.  The market value of certificates of deposit is based upon the discounted value of contractual cash flows.  The discount rate is determined using the rates currently offered on comparable instruments. Fair value estimates for deposits are considered Level 3 measures.

FHLB Advances and Other Borrowings:  Fair valuations for Banner’s FHLB advances are estimated using fair market values provided by the lender, the FHLB of Seattle.  The FHLB of Seattle prices advances by discounting the future contractual cash flows for individual advances using its current cost of funds curve to provide the discount rate.  This is considered to be a Level 2 input method.  Other borrowings are priced using discounted cash flows to the date of maturity based on using current rates at which such borrowings can currently be obtained. This fair value is considered to be a Level 3 measure.

Junior Subordinated Debentures:  Due to continued credit concerns in the capital markets and inactivity in the trust preferred markets that have limited the observability of market spreads (see earlier discussion above in determining the junior subordinated debentures’ fair market value), junior subordinated debentures have been classified as a Level 3 fair value measure.  Management believes that the credit risk adjusted spread and resulting discount rate utilized is indicative of those that would be used by market participants.

Derivatives:  Derivatives include interest rate swap agreements, interest rate lock commitments to originate loans held for sale and forward sales contracts to sell loans and securities related to mortgage banking activities. Fair values for these instruments, which generally change as a result of changes in the level of market interest rates, are estimated based on dealer quotes and secondary market sources. Management considers these to be Level 2 inputs.

Off-Balance Sheet Items: Off-balance sheet financial instruments include unfunded commitments to extend credit, including standby letters of credit, and commitments to purchase investment securities. The fair value of these instruments is not considered to be material. Other commitments to fund loans totaled $1.328 billion and $1.197 billion at March 31, 2015 and December 31, 2014, respectively, and have no carrying value at both dates, representing the cost of such commitments. There were no commitments to purchase securities at March 31, 2015 or at December 31, 2014.

Limitations: The fair value estimates presented herein are based on pertinent information available to management as of March 31, 2015 and December 31, 2014.  Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date and, therefore, current estimates of fair value may differ significantly from the amounts presented herein.

Fair value estimates are based on existing on- and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business.  The fair value has not been estimated for assets and liabilities that are not considered financial instruments.  Significant assets and liabilities that are not financial instruments include the deferred tax assets/liabilities; land, buildings and equipment; costs in excess of net assets acquired; and real estate held for sale.

LOANS RECEIVABLE AND THE ALLOWANCE FOR LOAN LOSSES

Receivables [Abstract]

LOANS RECEIVABLE AND THE ALLOWANCE FOR LOAN LOSSES

LOANS RECEIVABLE AND THE ALLOWANCE FOR LOAN LOSSES

The Banks originate residential mortgage loans for both portfolio investment and sale in the secondary market. At the time of origination, mortgage loans are designated as held for sale or held for investment. Loans held for sale are stated at the lower of cost or estimated market value determined on an aggregate basis. Net unrealized losses on loans held for sale are recognized through a valuation allowance by charges to income. The Banks also originate construction, land and land development, commercial and multifamily real estate, commercial business, agricultural business and consumer loans for portfolio investment. Loans receivable not designated as held for sale are recorded at the principal amount outstanding, net of deferred fees and origination costs, and discounts and premiums.  Loans acquired in business combinations are recorded at their fair value at the date of acquisition. Premiums, discounts and deferred loan fees and origination costs are amortized to maturity using the level-yield methodology.

Interest is accrued as earned unless management doubts the collectability of the loan or the unpaid interest. Interest accruals are generally discontinued when loans become 90 days past due for scheduled interest payments. All previously accrued but uncollected interest is deducted from interest income upon transfer to nonaccrual status. Future collection of interest is included in interest income based upon an assessment of the likelihood that the loans 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 loan may be uncollectable. Such interest is then recognized as income only if it is ultimately collected.

Loans receivable, including loans held for sale, at March 31, 2015 and December 31, 2014 are summarized as follows (dollars in thousands):

Total adjustable-rate loans	2,721,056		2,539,558
Total loans	$	4,114,818	$	3,833,820

The adjustable-rate loans have interest rate adjustment limitations and are generally indexed to various prime or London Inter-bank Offering Rate (LIBOR) rates, One to Five Year Constant Maturity Treasury Indices or FHLB advance rates.  Future market factors may affect the correlation of the interest rate adjustment with the rates the Banks pay on the short-term deposits that were primarily utilized to fund these loans.

Impaired Loans and the Allowance for Loan Losses.  A loan is considered impaired when, based on current information and circumstances, the Company determines it is probable that it will be unable to collect all amounts due according to the contractual terms of the loan agreement, including scheduled interest payments.  Impaired loans are comprised of loans on nonaccrual, troubled debt restructurings (TDRs) that are performing under their restructured terms, and loans that are 90 days or more past due, but are still on accrual.

Troubled Debt Restructures. Some of the Company’s loans are reported as TDRs.  Loans are reported as TDRs when the bank grants one or more concessions 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.  Our TDRs have generally not involved forgiveness of amounts due, but almost always include a modification of multiple factors; the most common combination includes interest rate, payment amount and maturity date. As a result of these concessions, restructured loans are impaired as the Company will not collect all amounts due, both principal and interest, in accordance with the terms of the original loan agreement.  Loans identified as TDRs are accounted for in accordance with the Company's impaired loan accounting policies.

Purchased loans, including loans acquired in business combinations, are recorded at their fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either purchased credit-impaired or purchased non-credit-impaired. Purchased credit-impaired loans reflect credit deterioration since origination such that it is probable at acquisition that the Company will be unable to collect all contractually required payments. The outstanding contractual unpaid principal balance of purchased credit-impaired loans, excluding acquisition accounting adjustments, was $9.1 million at March 31, 2015. The carrying balance of purchased credit-impaired loans was $5.7 million at March 31, 2015. There were no purchased credit-impaired loans at December 31, 2014 or March 31, 2014.

The following table presents the changes in the accretable yield for purchased credit-impaired loans for the three months ended March 31, 2015 and 2014 (in thousands):

⁽¹⁾  Loans without a specific allowance reserve have not been individually evaluated for impairment, but have been included in pools of homogeneous loans for evaluation of related allowance reserves.

⁽²⁾  Loans with a specific allowance reserve have been individually evaluated for impairment using either a discounted cash flow analysis or, for collateral dependent loans, current appraisals less costs to sell to establish realizable value.  These analyses may identify a specific impairment amount needed or may conclude that no reserve is needed.  Any specific impairment that is identified is included in the category’s Related Allowance column.

⁽¹⁾  Since these loans were already considered classified and/or on nonaccrual status prior to restructuring, the modifications did not have a material effect on the Company’s determination of the allowance for loan losses.

⁽²⁾  The majority of these modifications do not fit into one separate type, such as rate, term, amount, interest-only or payment, but instead are a combination of multiple types of modifications; therefore, they are disclosed in aggregate.

There were no TDRs which incurred a payment default within twelve months of the restructure date during the three-month periods ended March 31, 2015 and 2014.  A default on a TDR results in either a transfer to nonaccrual status or a partial charge-off.

Credit Quality Indicators:  To appropriately and effectively manage the ongoing credit quality of the Company’s loan portfolio, management has implemented a risk-rating or loan grading system for its loans.  The system is a tool to evaluate portfolio asset quality throughout each applicable loan’s life as an asset of the Company.  Generally, loans and leases are risk rated on an aggregate borrower/relationship basis with individual loans sharing similar ratings.  There are some instances when specific situations relating to individual loans will provide the basis for different risk ratings within the aggregate relationship.  Loans are graded on a scale of 1 to 9.  A description of the general characteristics of these categories is shown below:

Overall Risk Rating Definitions:  Risk-ratings contain both qualitative and quantitative measurements and take into account the financial strength of a borrower and the structure of the loan or lease.  Consequently, the definitions are to be applied in the context of each lending transaction and judgment must also be used to determine the appropriate risk rating, as it is not unusual for a loan or lease to exhibit characteristics of more than one risk-rating category.  Consideration for the final rating is centered in the borrower’s ability to repay, in a timely fashion, both principal and interest.  There were no material changes in the risk-rating or loan grading system in the three months ended March 31, 2015.

Risk Rating 1: Exceptional

A credit supported by exceptional financial strength, stability, and liquidity.  The risk rating of 1 is reserved for the Company’s top quality loans, generally reserved for investment grade credits underwritten to the standards of institutional credit providers.

Risk Rating 2: Excellent

A credit supported by excellent financial strength, stability and liquidity.  The risk rating of 2 is reserved for very strong and highly stable customers with ready access to alternative financing sources.

Risk Rating 3: Strong

A credit supported by good overall financial strength and stability.  Collateral margins are strong; cash flow is stable although susceptible to cyclical market changes.

Risk Rating 4: Acceptable

A credit supported by the borrower’s adequate financial strength and stability.  Assets and cash flow are reasonably sound and provide for orderly debt reduction.  Access to alternative financing sources will be more difficult to obtain.

Risk Rating 5: Watch

A credit with the characteristics of an acceptable credit which requires, however, more than the normal level of supervision and warrants formal quarterly management reporting.  Credits in this category are not yet criticized or classified, but due to adverse events or aspects of underwriting require closer than normal supervision. Generally, credits should be watch credits in most cases for six months or less as the impact of stress factors are analyzed.

Risk Rating 6: Special Mention

A credit with potential weaknesses that deserves management’s close attention is risk rated a 6.  If left uncorrected, these potential weaknesses will result in deterioration in the capacity to repay debt.  A key distinction between Special Mention and Substandard is that in a Special Mention credit, there are identified weaknesses that pose potential risk(s) to the repayment sources, versus well defined weaknesses that pose risk(s) to the repayment sources.  Assets in this category are expected to be in this category no more than 9-12 months as the potential weaknesses in the credit are resolved.

Risk Rating 7: Substandard

A credit with well defined weaknesses that jeopardize the ability to repay in full is risk rated a 7.  These credits are inadequately protected by either the sound net worth and payment capacity of the borrower or the value of pledged collateral.  These are credits with a distinct possibility of loss.  Loans headed for foreclosure and/or legal action due to deterioration are rated 7 or worse.

Risk Rating 8: Doubtful

A credit with an extremely high probability of loss is risk rated 8.  These credits have all the same critical weaknesses that are found in a substandard loan; however, the weaknesses are elevated to the point that based upon current information, collection or liquidation in full is improbable.  While some loss on doubtful credits is expected, pending events may strengthen a credit making the amount and timing of any loss indeterminable.  In these situations taking the loss is inappropriate until it is clear that the pending event has failed to strengthen the credit and improve the capacity to repay debt.

Risk Rating 9: Loss

A credit that is considered to be currently uncollectible or of such little value that it is no longer a viable Bank asset is risk rated 9.  Losses should be taken in the accounting period in which the credit is determined to be uncollectible.  Taking a loss does not mean that a credit has absolutely no recovery or salvage value but, rather, it is not practical or desirable to defer writing off the credit, even though partial recovery may occur in the future.

There were 42 sales of securities—available-for-sale totaling $22.3 million with a resulting net gain of $103,000 during the three months ended March 31, 2015. There were six sales of securities—available-for-sale totaling $28.2 million with a resulting net gain of $34,000 during the three months ended March 31, 2014.  At March 31, 2015, there were 59 securities—available for sale with unrealized losses, compared to 94 securities at December 31, 2014.  Management does not believe that any individual unrealized loss as of March 31, 2015 represents OTTI.  The decline in fair market values of these securities was generally due to changes in interest rates and changes in market-desired spreads subsequent to their purchase. There were no securities—available-for-sale on nonaccrual status at March 31, 2015 or 2014.

There were no sales of securities—held-to-maturity during the three months ended March 31, 2015 and 2014.  At March 31, 2015, there were ten securities—held-to-maturity with unrealized losses, compared to 25 securities at December 31, 2014.  Management does not believe that any individual unrealized loss as of March 31, 2015 represents OTTI.  The decline in fair market value of these securities was generally due to changes in interest rates and changes in market-desired spreads subsequent to their purchase. There were no securities—held-to-maturity on nonaccrual status at March 31, 2015 or 2014.

The amortized cost and estimated fair value of securities—held-to-maturity at March 31, 2015 and December 31, 2014, by contractual maturity, are shown below (in thousands).  Expected maturities will differ from contractual maturities because some securities may be called or prepaid with or without call or prepayment penalties.

FHLB STOCK

Banking and Thrift [Abstract]

FHLB STOCK

FHLB STOCK

The Banks’ investments in Federal Home Loan Bank of Seattle stock are carried at cost, which is its par value ($100 per share) and which reasonably approximates its fair value.  As members of the FHLB system, the Banks are required to maintain a minimum level of investment in FHLB stock based on specific percentages of their outstanding FHLB advances.  At March 31, 2015 and December 31, 2014, respectively, the Company had recorded $25.5 million and $27.0 million in investments in FHLB stock.  This stock is generally viewed as a long-term investment and it does not have a readily determinable fair value.  Ownership of FHLB stock is restricted to the FHLB and member institutions and can only be purchased and redeemed at par. For the three months ended March 31, 2015 and 2014, the Banks received dividend income of $7,000 and $9,000, respectively, on FHLB stock.

Management periodically evaluates FHLB stock for impairment.  Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value.  The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB.

The FHLB repurchased $2.0 million of the Banks' stock during the quarter ending March 31, 2015. On September 25, 2014, the FHLB of Seattle entered into an Agreement and Plan of Merger with and into the FHLB of Des Moines. The merger was approved by the members of both the Seattle and Des Moines Federal Home Loan Banks on February 27, 2015 and the merger is expected to be completed by mid-year 2015. Based on the above, the Company has determined there was no impairment on its FHLB stock investment as of March 31, 2015.

REO properties are recorded at the lower of the estimated fair value of the property, less expected selling costs, or the carrying value of the defaulted loan, establishing a new cost basis.  Subsequently, REO properties are carried at the lower of the new cost basis or updated fair market values, based on updated appraisals of the underlying properties, as received.  Valuation allowances on the carrying value of REO may be recognized based on updated appraisals or on management’s authorization to reduce the selling price of a property.

[1] The Pass category includes some performing loans that are part of homogenous pools which are not individually risk-rated. This includes all consumer loans, all one- to four-family residential loans and, as of March 31, 2015 and December 31, 2014, in the commercial business category, $120 million and $115 million, respectively, of credit-scored small business loans. As loans in these pools become non-performing, they are individually risk-rated.

[2] Non-performing loans include non-accrual loans and loans past due greater than 90 days and on accrual status.

[1] The majority of these modifications do not fit into one separate type, such as rate, term, amount, interest-only or payment, but instead are a combination of multiple types of modifications; therefore, they are disclosed in aggregate.

[2] Since these loans were already considered classified and/or on nonaccrual status prior to restructuring, the modifications did not have a material effect on the Company’s determination of the allowance for loan losses.

Options to purchase an additional 19,964 shares of common stock as of March 31, 2015 were not included in the computation of diluted earnings per share because their exercise price resulted in them being anti-dilutive. Also, as of March 31, 2015, the warrants originally issued to the U.S. Treasury in the fourth quarter of 2008 to purchase up to $18.6 million (243,998 shares, post reverse-split) of common stock were not included in the computation of diluted EPS for the quarters ended March 31, 2015 and 2014 because the exercise price of the warrants was greater than the average market price of common shares. In June 2013, the Treasury sold the warrants in a public auction. That sale did not change the Company's capital position and did not have any impact on the financial accounting and reporting for these securities.

Proposed Acquisition of AmericanWest Bank

On November 5, 2014, we announced the execution of a definitive agreement to purchase Starbuck Bancshares, Inc. (Starbuck) the bank holding company of AmericanWest Bank (AmericanWest), a Washington state chartered commercial bank headquartered in Spokane, Washington, with 94 branches serving markets in Washington, Oregon, Idaho, California and Utah. The merger agreement provides that Starbuck will merge with and into a wholly-owned subsidiary of the Company. Immediately following the merger, Starbuck's wholly owned bank subsidiary, AmericanWest will merge with Banner Bank. At March 31, 2015, Starbuck had $4.6 billion in assets, $3.0 billion in net loans, $3.7 billion in deposits and equity of $586 million, including AmericanWest's recent acquisition of Greater Sacramento Bancorp which was completed on February 6, 2015. The merged banks will operate under the Banner Bank brand. Under the terms of the agreement, the aggregate consideration to be received by Starbuck equity holders will consist of a fixed amount of 13.23 million shares of Banner common stock and $130.0 million in cash. Upon completion of the transaction, such shares will represent an approximately 38.8% pro forma ownership interest in Banner. The merger is expected to close early in the third quarter of 2015 and is subject to approval by regulatory agencies as well as other customary closing conditions. Upon completion of the AmericanWest merger, Banner Bank will have more than 190 locations in five western states, a significantly expanded customer base and meaningfully increased business opportunities.

Acquisition of Siuslaw Financial Group, Inc.

As of the close of business on March 6, 2015, the Company completed its acquisition of Siuslaw Financial Group (Siuslaw) and its subsidiary, Siuslaw Bank, an Oregon state chartered commercial bank with ten branches in Lane County, Oregon, including Eugene, Oregon. On that date Siuslaw was merged into Banner Corporation and Siuslaw Bank was merged into Banner Bank. The operating results produced by the ten branches acquired in the Siuslaw acquisition are included in Banner Bank's financial results beginning March 7, 2015 and the combined banks are operating under the Banner Bank name and brand. (See Note 4, Business Combinations, below in this Form 10-Q for additional information regarding the acquisition).

INCOME TAXES AND DEFERRED TAXES

Income Tax Disclosure [Abstract]

INCOME TAXES AND DEFERRED TAXES

INCOME TAXES AND DEFERRED TAXES

The Company files a consolidated income tax return including all of its wholly-owned subsidiaries on a calendar year basis. Income taxes are accounted for using the asset and liability method. Under this method, a deferred tax asset or liability is determined based on the enacted tax rates which will be in effect when the differences between the financial statement carrying amounts and tax bases of existing assets and liabilities are expected to be reported in the Company’s income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period of change. A valuation allowance is recognized as a reduction to deferred tax assets when management determines it is more likely than not that deferred tax assets will not be available to offset future income tax liabilities.

Accounting standards for income taxes prescribe a recognition threshold and measurement process for financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in a tax return, and also provide guidance on the de-recognition of previously recorded benefits and their classification, as well as the proper recording of interest and penalties, accounting in interim periods, disclosures and transition. The Company periodically reviews its income tax positions based on tax laws and regulations and financial reporting considerations, and records adjustments as appropriate. This review takes into consideration the status of current taxing authorities’ examinations of the Company’s tax returns, recent positions taken by the taxing authorities on similar transactions, if any, and the overall tax environment.

As of March 31, 2015, the Company had an insignificant amount of unrecognized tax benefits for uncertain tax positions, none of which would materially affect the effective tax rate if recognized. The Company does not anticipate that the amount of unrecognized tax benefits will significantly increase or decrease in the next twelve months. The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in the income tax expense. The Company files consolidated income tax returns in U.S. federal jurisdiction and in the Oregon and Idaho state jurisdictions. The tax years which remain subject to examination by the taxing authorities are the years ended December 31, 2013, 2012, and 2011.

Tax credit investments: The Company invests in low income housing tax credit funds that are designed to generate a return primarily through the realization of federal tax credits. As discussed more thoroughly in Note 3, the Company accounts for this in accordance with ASU 2014-01 and has applied it to all periods presented. The cost of tax credit investments is amortized over the life of the investment using a proportional amortization method and tax credit investment amortization expense is a component of provision for income taxes.

The following table presents the balances of the Company’s tax credit investments and related unfunded commitments at March 31, 2015 and 2014 (in thousands):
