NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Columbia Banking System, Inc.

1. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The interim unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X. The consolidated financial statements include the accounts of Columbia Banking System, Inc. (“we”, “our”, “Columbia” or the “Company”) and its subsidiaries, including its wholly owned banking subsidiary Columbia State Bank (“Columbia Bank” or the “Bank”) and West Coast Trust Company, Inc. (“West Coast Trust”). All intercompany transactions and accounts have been eliminated in consolidation. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of the results for the interim periods presented have been included. The results of operations for the nine months ended September 30, 2015 are not necessarily indicative of results to be anticipated for the year ending December 31, 2015. The accompanying interim unaudited consolidated financial statements should be read in conjunction with the financial statements and related notes contained in the Company’s 2014 Annual Report on Form 10-K.

Our results of operations for the three and nine month periods ended September 30, 2015 include the acquisition of Intermountain Community Bancorp (“Intermountain”) for the entire period. However, the results of operations for the prior year periods do not include the acquisition. See Note 3, Business Combinations, for further information regarding this acquisition.

Significant Accounting Policies

The significant accounting policies used in preparation of our consolidated financial statements are disclosed in our 2014 Annual Report on Form 10-K. There have not been any changes in our significant accounting policies compared to those contained in our 2014 Form 10-K disclosure for the year ended December 31, 2014.

2. Accounting Pronouncements Recently Issued

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the codification. For public companies, this update was to be effective for interim and annual periods beginning after December 15, 2016. However, in August 2015, the FASB issued ASU 2015-14, which delayed the effective date of ASU 2014-09 by one year and permits companies to voluntarily adopt the new standard as of the original effective date. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements, but does not expect the guidance to have a material impact on the Company’s consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments. the amendments in ASU 2015-16 require that the acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amount is determined. The acquirer is required to also record, in the same period’s financial statements, the effect on earnings as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. In addition, an entity is required to present separately on the face of the income statement or disclose in the notes to the financial statements the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The amendments in ASU 2015-16 are effective for years beginning after December 15, 2015. Early adoption is permitted for reporting periods for which financial statements have not been issued. The Company adopted the amendments in ASU 2015-16 during the current quarter.

3. Business Combinations

On November 1, 2014, the Company completed its acquisition of Intermountain. The Company paid $131.9 million in total consideration to acquire 100% of the equity interests of Intermountain. The primary reason for the acquisition was to expand the Company’s geographic footprint into the state of Idaho, consistent with its ongoing growth strategy.

The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their fair values as of the November 1, 2014 acquisition date. Initial accounting for deferred taxes was provisionally measured as of November 1, 2014. During the current quarter, the provisionally measured deferred taxes were finalized. The resulting adjustment was a decrease in other assets of $225 thousand

7

and a corresponding increase in goodwill of $225 thousand. There was no impact to earnings as a result of these adjustments. These adjustments were recorded as current period adjustments pursuant to the Company’s early adoption of ASU 2015-16. The application of the acquisition method of accounting resulted in recognition of goodwill of $38.8 million and a core deposit intangible of $10.9 million, or 1.75% of core deposits. The goodwill represents the excess purchase price over the fair value of the net assets acquired. The goodwill is not deductible for income tax purposes.

The table below summarizes the amounts recognized as of the acquisition date for each major class of assets acquired and liabilities assumed:

	November 1, 2014

The operating results of the Company reported herein include the operating results produced by the acquired assets and assumed liabilities for the period January 1, 2015 to September 30, 2015. Disclosure of the amount of Intermountain’s revenue and net income (excluding integration costs) included in Columbia’s consolidated income statement is impracticable due to the integration of the operations and accounting for this acquisition.

For illustrative purposes only, the following table presents certain unaudited pro forma information for the nine month period ended September 30, 2014. This unaudited pro forma information was calculated as if Intermountain had been acquired as of the beginning of the year prior to the date of acquisition. The unaudited pro forma information combines the historical results of Intermountain with the Company’s consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective period. The pro forma information is not indicative of what would have occurred had the acquisition occurred as of the beginning of the year prior to the acquisition. 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 the beginning of the year prior to the date of acquisition. 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, Columbia 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 connection with the Intermountain acquisition, Columbia recognized $428 thousand and $9.0 million in acquisition-related expenses for the three and nine month periods ended September 30, 2015, respectively, and recognized $459 thousand in acquisition-related expenses for the three and nine month periods ended September 30, 2014. In addition, related to the acquisition of West Coast Bancorp (“West Coast”) which was completed on April 1, 2013, Columbia recognized $72 thousand in acquisition-related expenses for the nine month period ended September 30, 2015, and $2.8 million and $4.4 million in acquisition-related expenses for the three and nine month periods ended September 30, 2014, respectively.

At September 30, 2015, there were 75 U.S. government agency and government-sponsored enterprise mortgage-backed securities and collateralized mortgage obligations securities in an unrealized loss position, of which 38 were in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where these investments fall within the yield curve and their individual characteristics. Because the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2015.

At September 30, 2015, there were 57 state and municipal government securities in an unrealized loss position, of which 28 were in a continuous loss position for 12 months or more. The unrealized losses on state and municipal securities were caused by interest rate changes or widening of market spreads subsequent to the purchase of the individual securities. Management monitors published credit ratings of these securities for adverse changes. As of September 30, 2015, none of the rated obligations of state and local government entities held by the Company had a below investment grade credit rating. Because the credit quality of these securities are investment grade and the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2015.

At September 30, 2015, there were six U.S. government agency and government-sponsored enterprise securities in an unrealized loss position, five of which were in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where these investments fall within the yield curve and their individual characteristics. Because the Company does not currently intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2015.

At September 30, 2015, there was one U.S. government security in an unrealized loss position which was in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where this investment falls within the yield curve and its individual characteristics. Because the Company does not currently intend to sell this security nor does the Company consider it more likely than not that it will be required to sell this security before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider this investment to be other-than-temporarily impaired at September 30, 2015.

At September 30, 2015, there was one other security in an unrealized loss position, which was in a continuous unrealized loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates and the additional risk premium investors are demanding for investment securities with these characteristics. The Company does not consider this investment to be other-than-temporarily impaired at September 30, 2015 as it has the intent and ability to hold the investment for sufficient time to allow for recovery in the market value.

5. Loans

The Company’s loan portfolio includes originated and purchased loans. Originated loans and purchased loans for which there was no evidence of credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments are referred to collectively as loans, excluding purchased credit impaired loans. Purchased loans for which there was, at acquisition date, evidence of credit deterioration since their origination and it was probable that we would be unable to collect all contractually required payments are referred to as purchased credit impaired loans, or “PCI loans.”

These loans are made on the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unrelated persons and do not involve more than the normal risk of collectability. The aggregate dollar amount of these loans was $10.1 million at September 30, 2015 and $13.2 million at December 31, 2014. During the first nine months of 2015, there were $6 thousand in advances and $3.1 million in repayments.

The Company’s loans classified as TDR are loans that have been modified or the borrower has been granted special concessions due to financial difficulties that, if not for the challenges of the borrower, the Company would not otherwise consider. The TDR modifications or concessions are made to increase the likelihood that these borrowers with financial difficulties will be able to satisfy their debt obligations as amended. The concessions granted in the restructurings completed in the three and nine month periods ending September 30, 2015 and 2014 largely consisted of maturity extensions, interest rate modifications or a combination of both. In limited circumstances, a reduction in the principal balance of the loan could also be made as a concession. Credit losses for loans classified as TDR are measured on the same basis as impaired loans. For impaired loans, an allowance is established when the collateral value less selling costs (or discounted cash flows or observable market price) of the impaired loan is lower than the recorded investment of that loan.

The Company had no commitments to lend additional funds on loans classified as TDR as of September 30, 2015 and December 31, 2014. The Company did not have any loans modified as TDR that defaulted within twelve months of being modified as TDR during the three and nine month periods ended September 30, 2015 and 2014.

Purchased Credit Impaired Loans (“PCI Loans”)

PCI loans are accounted for under ASC 310-30 and initially measured at fair value based on expected future cash flows over the life of the loans. Loans that have common risk characteristics are aggregated into pools. The Company remeasures contractual and expected cash flows, at the pool-level, on a quarterly basis.

Contractual cash flows are calculated based upon the loan pool terms after applying a prepayment factor. Calculation of the applied prepayment factor for contractual cash flows is the same as described below for expected cash flows.

Inputs to the determination of expected cash flows include cumulative default and prepayment data as well as loss severity and recovery lag information. Cumulative default and prepayment data are calculated via a transition matrix. The transition matrix is a matrix of probability values that specifies the probability of a loan pool transitioning into a particular delinquency state (e.g. 0-30 days past due, 31 to 60 days, etc.) given its delinquency state at the remeasurement date. Loss severity factors

18

are based upon either actual charge-off data within the loan pools or industry averages and recovery lags are based upon the collateral within the loan pools.

The excess of cash flows expected to be collected over the initial fair value of purchased credit impaired loans is referred to as the accretable yield and is accreted into interest income over the estimated life of the acquired loans using the effective yield method. Other adjustments to the accretable yield include changes in the estimated remaining life of the acquired loans, changes in expected cash flows and changes of indices for acquired loans with variable interest rates.

6. Allowance for Loan and Lease Losses and Unfunded Commitments and Letters of Credit

Loans, excluding PCI loans

We maintain an allowance for loan and lease losses (“ALLL”) to absorb losses inherent in the loan portfolio. The size of the ALLL is determined through quarterly assessments of the probable estimated losses in the loan portfolio. Our methodology for making such assessments and determining the adequacy of the ALLL includes the following key elements:

1. General valuation allowance consistent with the Contingencies topic of the FASB ASC.

2. Classified loss reserves on specific relationships. Specific allowances for identified problem loans are determined in accordance with the Receivables topic of the FASB ASC.

3. The unallocated allowance provides for other factors inherent in our loan portfolio that may not have been contemplated in the general and specific components of the allowance. This unallocated amount generally comprises less than 5% of the allowance. The unallocated amount is reviewed quarterly based on trends in credit losses, the results of credit reviews and overall economic trends.

19

The general valuation allowance is calculated quarterly using quantitative and qualitative information about specific loan classes. The minimum required level with respect to which an entity develops a methodology to determine its ALLL is by general categories of loans, such as commercial business, real estate, and consumer. However, the Company’s methodology in determining its ALLL is prepared in a more detailed manner at the loan class level, utilizing specific categories such as commercial business secured, commercial business unsecured, real estate commercial land, and real estate income property multifamily. The quantitative information uses historical losses from a specific loan class and incorporates the loan’s risk rating migration from origination to the point of loss based upon the consideration of an appropriate look back period.

A loan’s risk rating is primarily determined based upon the borrower’s ability to fulfill its debt obligation from a cash flow perspective. In the event there is financial deterioration of the borrower, the borrower’s other sources of income or repayment are also considered, including recent appraisal values for collateral dependent loans. The qualitative information takes into account general economic and business conditions affecting our marketplace, seasoning of the loan portfolio, duration of the business cycle, etc. to ensure our methodologies reflect the current economic environment and other factors as using historical loss information exclusively may not give an accurate estimate of inherent losses within the Company’s loan portfolio.

When a loan is deemed to be impaired, the Company has to determine if a specific valuation allowance is required for that loan. The specific valuation allowance is a reserve, calculated at the individual loan level, for each loan determined to be both impaired and containing a value less than its recorded investment. The Company measures the impairment based on the discounted expected future cash flows, observable market price, or the fair value of the collateral less selling costs if the loan is collateral dependent or if foreclosure is probable. The specific reserve for each loan is equal to the difference between the recorded investment in the loan and its determined impairment value.

The ALLL is increased by provisions for loan and lease losses (“provision”) charged to expense, and is reduced by loans charged off, net of recoveries or a recovery of previous provisions. While the Company’s management believes the best information available is used to determine the ALLL, changes in market conditions could result in adjustments to the ALLL, affecting net income, if circumstances differ from the assumptions used in determining the ALLL.

We have used the same methodology for ALLL calculations during the nine months ended September 30, 2015 and 2014. Adjustments to the percentages of the ALLL allocated to loan categories are made based on trends with respect to delinquencies and problem loans within each class of loans. The Company reviews the ALLL quantitative and qualitative methodology on a quarterly basis and makes adjustments when appropriate. The Company continues to strive towards maintaining a conservative approach to credit quality and will continue to make revisions to our ALLL as necessary to maintain adequate reserves. The Company carefully monitors the loan portfolio and continues to emphasize the importance of credit quality.

Once it is determined that all or a portion of a loan balance is uncollectable, and the amount can be reasonably estimated, the uncollectable portion of the loan is charged-off.

PCI Loans

Purchased credit impaired loans that have common risk characteristics are aggregated into loan pools. When required, we record impairment, at the pool-level, to adjust the pool’s carrying value to its net present value of expected future cash flows. Quarterly, we re-measure expected loan pool cash flows. If, due to credit deterioration, the present value of expected cash flows is less than carrying value, we reduce the loan pool’s carrying value by adjusting the ALLL with an impairment charge to earnings which is recorded as provision for loan losses. If credit quality improves and the present value of expected cash flows exceeds carrying value, we increase the loan pool’s carrying value by recapturing previously recorded ALLL, if any. See Note 5, Loans, for further discussion of the accounting for PCI loans.

Credit losses attributable to draws on purchased credit impaired loans, advanced subsequent to the loan purchase date, are accounted for under ASC 450-20 and those amounts are also subject to the Company’s internal and external credit review. An ALLL is estimated in a similar manner as loans, excluding PCI loans, and a provision for loan losses is charged to earnings as necessary.

Risk Elements

The extension of credit in the form of loans or other credit products to individuals and businesses is one of our principal business activities. Our policies and applicable laws and regulations require risk analysis as well as ongoing portfolio and credit management. We manage our credit risk through lending limit constraints, credit review, approval policies and extensive, ongoing internal monitoring. We also manage credit risk through diversification of the loan portfolio by type of loan, type of industry and type of borrower and by limiting the aggregation of debt to a single borrower.

Risk ratings are reviewed and updated whenever appropriate, with more periodic reviews as the risk and dollar value of loss on the loan increases. In the event full collection of principal and interest is not reasonably assured, the loan is appropriately downgraded and, if warranted, placed on nonaccrual status even though the loan may be current as to principal and interest payments. Additionally, we assess whether an impairment of a loan warrants specific reserves or a write-down of the loan.

Pass loans are generally considered to have sufficient sources of repayment in order to repay the loan in full in accordance with all terms and conditions. Special mention loans have potential weaknesses that, if left uncorrected, may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Loans with a risk rating of Substandard or worse are reported as classified loans in our ALLL analysis. We review these loans to assess the ability of our borrowers to service all interest and principal obligations and, as a result, the risk rating may be adjusted accordingly. Substandard loans reflect loans where a loss is possible if loan weaknesses are not corrected. Doubtful loans have a high probability of loss, however, the amount of loss has not yet been determined. Loss loans are considered uncollectable and when identified, are charged off.

8. FDIC Loss-sharing Asset and Covered Assets

We are a party to eight loss-sharing agreements with the FDIC relating to four FDIC-assisted acquisitions. Such agreements cover a substantial portion of losses incurred on acquired covered loans and OREO. The loss-sharing agreements relate to the acquisitions of (1) Columbia River Bank in January 2010, (2) American Marine Bank in January 2010, (3) Summit Bank in May 2011, and (4) First Heritage Bank in May 2011. Under the terms of the loss-sharing agreements, the FDIC will absorb 80% of losses and share in 80% of loss recoveries up to specified amounts. With respect to loss-sharing agreements for two acquisitions completed in 2010, after those specified amounts, the FDIC will absorb 95% of losses and share in 95% of loss recoveries. The loss-sharing provisions of the agreements for non-single family and single family mortgage loans are in effect for five and ten years, respectively and the loss recovery provisions are in effect for eight and ten years, respectively. The loss-sharing provisions for the Columbia River Bank and American Marine Bank non-single family covered assets were effective through March 31, 2015. Accordingly, further activity will be limited to recoveries through the first quarter of 2018 for assets covered by these loss-sharing agreements.

Ten years and forty-five days after the applicable acquisition dates, the Bank must pay to the FDIC a clawback in the event the losses from the acquisitions fail to reach stated levels. The amount of the clawback is determined by a formula specified in each individual loss-sharing agreement. As of September 30, 2015, the net present value of the Bank’s estimated clawback liability was $4.3 million, which was included in other liabilities on the consolidated balance sheets.

At September 30, 2015, the FDIC loss-sharing asset was comprised of a $6.7 million FDIC indemnification asset and a $1.4 million FDIC receivable. The indemnification asset represents the net present value of cash flows the Company expects to collect from the FDIC under the loss-sharing agreements and the FDIC receivable represents amounts from the FDIC for which the Company has requested reimbursement but has not yet received reimbursement.

For PCI loans, the Company remeasures contractual and expected cash flows on a quarterly basis. When the quarterly remeasurement process results in a decrease in expected cash flows due to an increase in expected credit losses, impairment is recorded. As a result of this impairment, for loans covered by loss-sharing agreements with respect to which the loss-sharing provisions are still effective, the indemnification asset is increased to reflect anticipated future cash to be received from the FDIC. Consistent with the loss-sharing agreements between the Company and the FDIC, the amount of the increase to the indemnification asset is measured as 80% of the resulting impairment.

Alternatively, when the quarterly remeasurement results in an increase in expected future cash flows due to a decrease in expected credit losses, the nonaccretable difference decreases and the effective yield of the related loan portfolio is increased. As a result of the improved expected cash flows, for loans covered by loss-sharing agreements with respect to which the loss-sharing provisions are still effective, the indemnification asset would be reduced first by the amount of any impairment previously recorded and, second, by increased amortization over the remaining life of the related loss-sharing agreement.

9. Goodwill and Other Intangible Assets

In accordance with the Intangibles – Goodwill and Other topic of the FASB ASC, goodwill is not amortized but is reviewed for potential impairment at the reporting unit level. Management analyzes its goodwill for impairment on an annual basis on July 31 and between annual tests in certain circumstances such as material adverse changes in legal, business, regulatory and economic factors. An impairment loss is recorded to the extent that the carrying amount of goodwill exceeds its implied fair value. The Company performed an impairment assessment as of July 31, 2015 and concluded that there was no impairment.

The core deposit intangible (“CDI”) is evaluated for impairment if events and circumstances indicate a possible impairment. The CDI is amortized on an accelerated basis over an estimated life of 10 years.

10. Derivatives and Balance Sheet Offsetting

The Company periodically enters into certain commercial loan interest rate swap agreements in order to provide commercial loan customers the ability to convert from variable to fixed interest rates. Under these agreements, the Company enters into a variable-rate loan agreement with a customer in addition to a swap agreement. This swap agreement effectively converts the customer’s variable rate loan into a fixed rate. The Company then enters into a corresponding swap agreement with a third-party in order to offset its exposure on the variable and fixed components of the customer agreement. As the interest rate swap agreements with the customers and third parties are not designated as hedges under the Derivatives and Hedging topic of the FASB ASC, the instruments are marked to market in earnings. The notional amount of open interest rate swap agreements at September 30, 2015 and December 31, 2014 was $226.8 million and $215.6 million, respectively. During the three and nine months ended September 30, 2015, a mark-to-market loss of $6 thousand and $2 thousand, respectively was recorded to other noninterest expense. There were no earnings impacts for the three or nine month periods ending September 30, 2014.

The following table presents the fair value of derivatives not designated as hedging instruments at September 30, 2015 and December 31, 2014:

The Company is party to interest rate contracts and repurchase agreements that are subject to enforceable master netting arrangements or similar agreements. Under these agreements, the Company may have the right to net settle multiple contracts with the same counterparty. The following tables show the gross interest rate swap agreements and repurchase agreements in the consolidated balance sheets and the respective collateral received or pledged in the form of other financial instruments, which are generally marketable securities. The collateral amounts in these tables are limited to the outstanding balances of the related asset or liability. Therefore, instances of overcollateralization are not shown.

The collateral utilized for the Company’s repurchase agreements is subject to market fluctuations as well as prepayments of principal. The Company monitors the risk of the fair value of its pledged collateral falling below acceptable amounts based on the type of the underlying repurchase agreement. The pledged collateral related to the Company’s term wholesale repurchase agreement, which matures in 2018, is monitored on a monthly basis and additional capital is pledged when necessary. The pledged collateral related to the Company’s sweep repurchase agreements, which mature on a daily basis, is monitored on a daily basis as the underlying sweep accounts can have daily transaction activity and the amount of pledged collateral is adjusted as necessary.

11. Shareholders’ Equity

Preferred Stock. In conjunction with the 2013 acquisition of West Coast, the Company issued 8,782 shares of mandatorily convertible cumulative participating preferred stock, Series B (“Series B Preferred Stock”). The Series B Preferred Stock is not subject to the operation of a sinking fund. The Series B Preferred Stock is not redeemable by the Company and is perpetual with no maturity. The holders of Series B Preferred Stock have no general voting rights. If the Company declares and pays a dividend to its common shareholders, it must declare and pay to its holders of Series B Preferred Stock, on the same date, a dividend in an amount per share of the Series B Preferred Stock that is intended to provide such holders dividends in the amount they would have received if shares of Series B Preferred Stock had been converted into common stock as of that date. The outstanding shares of Series B Preferred Stock are convertible into 102,363 shares of Company common stock.

Dividends. On January 29, 2015, the Company declared a quarterly cash dividend of $0.16 per common share and common share equivalent for holders of preferred stock, and a special cash dividend of $0.14 per common share and common share equivalent for holders of preferred stock, both payable on February 25, 2015 to shareholders of record at the close of business on February 11, 2015.

On April 22, 2015, the Company declared a regular quarterly cash dividend of $0.18 per common share and common share equivalent for holders of preferred stock, and a special cash dividend of $0.16 per common share and common share equivalent for holders of preferred stock, both payable on May 20, 2015 to shareholders of record at the close of business on May 6, 2015.

On July 23, 2015, the Company declared a regular quarterly cash dividend of $0.18 per common share and common share equivalent for holders of preferred stock, and a special cash dividend of $0.16 per common share and common share equivalent for holders of preferred stock, both payable on August 19, 2015 to shareholders of record at the close of business on August 5, 2015.

Subsequent to quarter end, on October 29, 2015, the Company declared a regular quarterly cash dividend of $0.18 per common share and common share equivalent for holders of preferred stock, and a special cash dividend of $0.18 per common share and common share equivalent for holders of preferred stock, both payable on November 25, 2015 to shareholders of record at the close of business on November 11, 2015.

The payment of cash dividends is subject to federal regulatory requirements for capital levels and other restrictions. In addition, the cash dividends paid by Columbia Bank to the Company are subject to both federal and state regulatory requirements.

13. Fair Value Accounting and Measurement

The Fair Value Measurements and Disclosures topic of the FASB ASC defines fair value, establishes a consistent framework for measuring fair value and expands disclosure requirements about fair value. We hold fixed and variable rate interest-bearing securities, investments in marketable equity securities and certain other financial instruments, which are carried at fair value. Fair value is determined based upon quoted prices when available or through the use of alternative approaches, such as matrix or model pricing, when market quotes are not readily accessible or available.

The valuation techniques are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our own market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1 – Quoted prices for identical instruments in active markets that are accessible at the measurement date.

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable.

Fair values are determined as follows:

Securities at fair value are priced using a combination of market activity, industry recognized information sources, yield curves, discounted cash flow models and other factors. These fair value calculations are considered a Level 2 input method under the provisions of the Fair Value Measurements and Disclosures topic of the FASB ASC for all securities other than U.S. Treasury notes, which are considered a Level 1 input method.

Interest rate contract positions are valued in models, which use as their basis, readily observable market parameters and are classified within Level 2 of the valuation hierarchy.

32

The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis at September 30, 2015 and December 31, 2014 by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement:

Nonrecurring Measurements

Certain assets and liabilities are measured at fair value on a nonrecurring basis after initial recognition such as loans measured for impairment and OREO. The following methods were used to estimate the fair value of each such class of financial instrument:

Impaired loans—A loan is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, a loan’s observable market price, or the fair market value of the collateral less estimated costs to sell if the loan is a collateral-dependent loan. Generally, the Company utilizes the fair market value of the collateral to measure impairment. The impairment evaluations are performed in conjunction with the ALLL process on a quarterly basis by officers in the Special Credits group, which reports to the Chief Credit Officer. The Real Estate Appraisal Services Department (“REASD”), which also reports to the Chief Credit Officer, is responsible for obtaining appraisals from third-parties or performing internal evaluations. If an appraisal is obtained from a third-party, the REASD reviews the appraisal to evaluate the adequacy of the appraisal report, including its scope, methods, accuracy, and reasonableness.

Other real estate owned—OREO is real property that the Bank has taken ownership of in partial or full satisfaction of a loan or loans. OREO is generally measured based on the property’s fair market value as indicated by an appraisal or a letter of intent to purchase. OREO is initially recorded at the fair value less estimated costs to sell. This amount becomes the property’s new basis. Any fair value adjustments based on the property’s fair value less estimated costs to sell at the date of acquisition are charged to the ALLL, or in the event of a write-up without previous losses charged to the ALLL, a credit to earnings is recorded. Management periodically reviews OREO in an effort to ensure the property is recorded at its fair value, net of estimated costs to sell. Any fair value adjustments subsequent to acquisition are charged or credited to earnings. The initial and subsequent evaluations are performed by officers in the Special Credits group, which reports to the Chief Credit Officer. The REASD obtains appraisals from third-parties for OREO and performs internal evaluations. If an appraisal is obtained from a third-party, the REASD reviews the appraisal to evaluate the adequacy of the appraisal report, including its scope, methods, accuracy, and reasonableness.

The following tables set forth information related to the Company’s assets that were measured using fair value estimates on a nonrecurring basis during the current and prior year quarterly periods:

Fair value of financial instruments

Because broadly traded markets do not exist for most of the Company’s financial instruments, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein do not represent, and should not be construed to represent, the underlying value of the Company.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Cash and due from banks and interest-earning deposits with banks—The fair value of financial instruments that are short-term or reprice frequently and that have little or no risk are considered to have a fair value that approximates carrying value (Level 1).

Securities available for sale—Securities at fair value, other than U.S. Treasury Notes, are priced using a combination of market activity, industry recognized information sources, yield curves, discounted cash flow models and other factors (Level 2). U.S. Treasury Notes are priced using quotes in active markets (Level 1).

Federal Home Loan Bank stock—The fair value is based upon the par value of the stock which equates to its carrying value (Level 2).

Loans held for sale—The carrying amount of loans held for sale approximates their fair values due to the short period of time between the origination and sale dates (Level 2).

Loans—Loans are not recorded at fair value on a recurring basis. Nonrecurring fair value adjustments are periodically recorded on impaired loans that are measured for impairment based on the fair value of collateral. For most performing loans, fair value is estimated using expected duration and lending rates that would have been offered on September 30, 2015 or December 31, 2014, for loans which mirror the attributes of the loans with similar rate structures and average maturities. The fair values resulting from these calculations are reduced by an amount representing the change in estimated fair value attributable to changes in borrowers’ credit quality since the loans were originated. For nonperforming loans, fair value is estimated by applying a valuation discount based upon loan sales data from the FDIC. For PCI loans, fair value is estimated by discounting the expected future cash flows using a lending rate that would have been offered on September 30, 2015 (Level 3).

FDIC loss-sharing asset —The fair value of the FDIC loss-sharing asset is estimated based on discounting the expected future cash flows using an estimated market rate (Level 3).

Interest rate contracts—Interest rate swap positions are valued in models, which use readily observable market parameters as their basis (Level 2).

Deposits—For deposits with no contractual maturity, the fair value is equal to the carrying value (Level 1). The fair value of fixed maturity deposits is based on discounted cash flows using the difference between the deposit rate and current market rates for deposits of similar remaining maturities (Level 2).

FHLB advances—The fair value of FHLB advances is estimated based on discounting the future cash flows using the market rate currently offered (Level 2).

Repurchase Agreements—The fair value of term repurchase agreements is estimated based on discounting the future cash flows using the market rate currently offered. The carrying amount of sweep repurchase agreements approximates their fair values due to the short period of time between repricing dates (Level 2).

Other Borrowings— Other borrowings are trust preferred obligations assumed by the Company in the Intermountain acquisition. The fair value is estimated as the carrying value as these obligations are redeemable and a market participant would expect redemption in the near-term (Level 2).

Other Financial Instruments—The majority of our commitments to extend credit and standby letters of credit carry current market interest rates if converted to loans, as such, carrying value is assumed to equal fair value.

36

The following tables summarize carrying amounts and estimated fair values of selected financial instruments as well as assumptions used by the Company in estimating fair value at September 30, 2015 and December 31, 2014:

14. Earnings per Common Share

The Company applies the two-class method of computing basic and diluted EPS. Under the two-class method, EPS is determined for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. The Company issues restricted shares under share-based compensation plans and preferred shares which qualify as participating securities.

37

The following table sets forth the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2015 and 2014:

__________

(1) Earnings allocated to common shareholders for basic and diluted EPS may differ under the two-class method as a result of adding common stock equivalents for options and warrants to dilutive shares outstanding, which alters the ratio used to allocate earnings to common shareholders and participating securities for the purposes of calculating diluted EPS.

15. Branch Sales

On August 23, 2014, Columbia completed a branch sale transaction to Sound Community Bancorp. In the transaction, Columbia sold three branches and related assets and deposit liabilities to Sound Community Bancorp. The transaction was completed with a transfer of $22.2 million in deposits to Sound Community Bancorp in exchange for a deposit premium of 2.35%. Also included in the branch sale were $1.1 million in loans and $3.8 million in premises and equipment. The Company recognized a gain of $565 thousand related to the deposit premium, which was recorded in the line item Other noninterest income in the Consolidated Statements of Income. In addition, the Company recorded a $50 thousand loss on the disposal of premises and equipment related to this transaction, which was recorded in the line item Other noninterest expense in the Consolidated Statements of Income.

CRITICAL ACCOUNTING POLICIES

Management has identified the accounting policies related to the ALLL, business combinations, PCI loans, FDIC loss-sharing asset and the valuation and recoverability of goodwill as critical to an understanding of our financial statements. These policies and related estimates are discussed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operation” under the headings “Allowance for Loan and Lease Losses”, “Business Combinations”, “Purchased Credit Impaired Loans”, “FDIC Loss-sharing Asset” and “Valuation and Recoverability of Goodwill” in our 2014 Annual Report on Form 10-K. There have not been any material changes in our critical accounting policies as compared to those disclosed in our 2014 Annual Report on Form 10-K.

RESULTS OF OPERATIONS

Our results of operations are dependent to a large degree on our net interest income. We also generate noninterest income through service charges and fees, merchant services fees, and bank owned life insurance. Our operating expenses consist primarily of compensation and employee benefits, occupancy, merchant card processing, data processing and legal and professional fees. Like most financial institutions, our interest income and cost of funds are affected significantly by general economic conditions, particularly changes in market interest rates, and by government policies and actions of regulatory authorities.

On November 1, 2014, the Company completed its acquisition of Intermountain. The Company acquired approximately $964.4 million in assets, including $502.6 million in loans measured at fair value, and approximately $736.8 million in deposits. Due to the timing of this acquisition, our results of operations for the nine month period ended September 30, 2015 include the acquisition for the entire period, however the prior year period does not include the acquisition. See Note 3 to the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report for further information regarding this acquisition.

Earnings Summary

The Company reported net income for the third quarter of $25.8 million or $0.45 per diluted common share, compared to $21.6 million or $0.41 per diluted common share for the third quarter of 2014. The increase in net income for the current quarter compared to the prior year period was due to a combination of higher net interest income and noninterest income, partially offset by higher noninterest expense. These fluctuations were primarily due to the timing of the acquisition of Intermountain, as noted above.

Comparison of current quarter to prior year period

Revenue (net interest income plus noninterest income) for the three months ended September 30, 2015 was $104.2 million, 13% higher than the same period in 2014. The increase in revenue was a result of higher net interest income arising not only from the loans and securities acquired in the Intermountain transaction but also organic loan growth. Also contributing to the increase in revenue was higher noninterest income due to both a decrease in the expense recorded for the change in the FDIC loss-sharing asset as well as an increase in service charges and other fees. For a more complete discussion of these topics, please refer to the net interest income and noninterest income sections contained in the ensuing pages.

The provision for loan and lease losses for the third quarter of 2015 was $2.8 million compared to a provision of $980 thousand during the third quarter of 2014. The provision recorded in the third quarter of 2015 was due to the recording of a $3.3 million provision on loans, excluding PCI loans, partially offset by provision recapture of $519 thousand related to PCI loans. For a more complete discussion of this topic, please refer to the provision for loan and lease losses section contained in the ensuing pages.

Total noninterest expense for the quarter ended September 30, 2015 was $64.1 million, up from $60.0 million for the third quarter of 2014. The increase from the prior-year period was primarily due to additional noninterest expense stemming from the growth resulting from the Intermountain acquisition, partially offset by lower acquisition-related expenses recorded during the third quarter of 2015. For a more complete discussion of this topic, please refer to the noninterest expense section contained in the ensuing pages.

40

Net income was positively affected by the pre-tax earnings impact of the FDIC acquired loan portfolios for the current quarter and year-to-date periods, but was negatively affected by the pre-tax earnings impact of the FDIC acquired loan portfolios during the prior year periods. The negative effect of the FDIC acquired loan portfolios in the prior year periods were primarily due to greater amortization of the FDIC loss-sharing asset recorded in the prior year periods. With the recent expiration of our two largest FDIC loss-sharing agreements, the amortization of the FDIC loss-sharing asset has declined. The following table illustrates the impact to earnings associated with the Company’s FDIC acquired loan portfolios for the periods indicated:

	Three Months Ended September 30,						Nine Months Ended September 30,

(1) For additional information on the FDIC loss-sharing asset, please see the “FDIC Loss-sharing Asset” section of this Management’s Discussion and Analysis and Note 8 to the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

Comparison of current year-to-date to prior year period

Revenue (net interest income plus noninterest income) for the nine months ended September 30, 2015 was $309.8 million, compared to $269.8 million for the same period in 2014. The increase in revenue was a result of higher net interest income arising not only from the loans and securities acquired in the Intermountain transaction but also from organic loan growth. Also contributing to the increase in revenue was higher noninterest income due to both a decrease in the expense recorded for the change in the FDIC loss-sharing asset as well as an increase in service charges and other fees. For a more complete discussion of this topic, please refer to the net interest income section and noninterest income sections contained in the ensuing pages.

The provision for loan and lease losses for the nine months ended September 30, 2015 was $6.2 million compared to a provision of $5.0 million for the first nine months of 2014. The $6.2 million provision was due to the recording of a $3.6 million provision on loans, excluding PCI loans and a $2.6 million provision on PCI loans. For a more complete discussion of this topic, please refer to the provision for loan and lease losses section contained in the ensuing pages.

Total noninterest expense for the nine months ended September 30, 2015 was $199.3 million, a 14% increase from the first nine months of 2014. The increase from the prior-year period was primarily due to additional noninterest expense stemming from the growth resulting from the Intermountain acquisition as well as higher acquisition-related expenses recorded during the nine months ended September 30, 2015. For a more complete discussion of this topic, please refer to the noninterest expense section contained in the ensuing pages.

Net Interest Income

Comparison of current quarter to prior year period

Net interest income for the third quarter of 2015 was $81.7 million, an increase of 7% from $76.2 million for the same quarter in 2014. The increase in net interest income was due to interest income earned from a larger volume of earning assets. Growth in earning assets was driven not only by loans and securities acquired in the Intermountain transaction but also by loans originated for investment. Net interest income was higher in the current period despite lower incremental accretion income from acquired loans and lower interest income on taxable securities. As shown in the table below, incremental accretion income continued to decline which was reflective of the decreasing balance of certain acquired loan portfolios. Interest income on taxable securities was lower in the current period due to the previously disclosed $2.6 million adjustment recorded in the prior year period. For additional information on the Company’s accounting policies related to recording interest income on loans and

the adjustment recorded during 2014, please refer to “Item 8. Financial Statements and Supplementary Data” in our 2014 Annual Report on Form 10-K.

The Company’s net interest margin (tax equivalent) decreased to 4.37% in the third quarter of 2015, from 4.85% for the same quarter last year. This decrease was due to lower incremental accretion income on acquired loan portfolios. The Company’s operating net interest margin (tax equivalent) ⁽¹⁾ decreased to 4.18% from 4.22% due to lower rates on loans and securities.

Comparison of current year-to-date to prior year period

Net interest income for the nine months ended September 30, 2015 was $243.1 million, an increase of 8% from $225.3 million for the same period in 2014. The increase in net interest income was due to higher average loan and securities balances during the current year as a result of the acquisition of Intermountain and organic growth in the loan portfolio. The Company’s net interest margin (tax equivalent) decreased to 4.39% for the first nine months of 2015, from 4.86% for the prior year period. The decrease in the Company’s net interest margin (tax equivalent) was primarily due to lower accretion income on the acquired loan portfolios. As shown in the table below, the Company recorded $21.2 million in total incremental accretion during the nine months ended September 30, 2015, a decrease of $11.9 million from the prior year period. The Company’s operating net interest margin (tax equivalent) (1) for the nine months ended September 30, 2015 decreased modestly to 4.18% from 4.23% due to lower rates on loans and securities.

The following table shows the impact to interest income of incremental accretion income as well as the net interest margin and operating net interest margin for the periods presented:

Provision for Loan and Lease Losses

Comparison of current quarter to prior year period

During the third quarter of 2015, the Company recorded a $2.8 million provision expense compared with a provision expense of $1.0 million during the third quarter of 2014. The $2.8 million net provision for loan and lease losses recorded during the current quarter was driven by loans, excluding PCI loans, for which Columbia recorded a provision of $3.3 million, partially offset by provision recapture of $519 thousand related to PCI loans. The $2.3 million provision related to loans, excluding PCI loans, was due to organic loan growth, charge-off activity during the current quarter and higher loss rates in the substandard category. The provision recapture recorded relating to PCI loans was due to the increase in the present value of expected future cash flows as remeasured during the current quarter, compared to the present value of expected future cash flows measured during the second quarter of 2015. The amount of provision was calculated in accordance with the Company’s methodology for determining the ALLL, discussed in Note 6 to the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

Comparison of current year-to-date to prior year period

The provision for loan and lease losses for the nine months ended September 30, 2015 was $6.2 million compared with provision expense of $5.0 million during the same period in 2014. The $6.2 million provision expense for loans recorded for the current year-to-date period included a provision of $3.6 million for loans, excluding PCI loans and a provision of $2.6 million related to PCI loans. The provision of $3.6 million related to loans, excluding PCI loans, was due to the combination of loan growth and net loan charge-offs experienced in the period. The $2.6 million in provision expense for PCI loans was primarily due to the decrease in the present value of expected future cash flows as remeasured during the current period, compared to the present value of expected future cash flows at the end of 2014, net of activity during the period. The amount of provision was calculated in accordance with the Company’s methodology for determining the ALLL, discussed in Note 6 to the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

Comparison of current quarter to prior year period

Noninterest income was $22.5 million for the third quarter of 2015, compared to $15.9 million for the same period in 2014. The increase was primarily due to lower expense recorded for the change in FDIC loss-sharing asset, which was $3.2 million less in the current quarter. Also contributing to the increase was an additional $1.6 million in revenue earned from service charges and other fees which reflected the larger customer base established in the Intermountain acquisition. Finally, other noninterest income was up $1.1 million from a combination of revenue from a larger customer base and $550 thousand in additional loan sale gains.

The change in FDIC loss-sharing asset has been a significant component of noninterest income. Changes in the asset are primarily driven by amortization of the asset, the provision recorded for reimbursable losses on covered loans and write-downs of covered other real estate owned (“OREO”). For the third quarter of 2015, the change in the asset was primarily driven by $1.4 million of amortization of the asset. The decline in amortization recorded in the current quarter was due to the recent expiration of our two most significant FDIC loss-sharing agreements. For the same period in 2014, there was $4.0 million of amortization of the asset, $416 thousand related to the provision recapture recorded on covered loans and sales of OREO of $383 thousand. For additional information on the FDIC loss-sharing asset, please see the “FDIC Loss-sharing Asset” section of this Management’s Discussion and Analysis and Note 8 to the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

Comparison of current year-to-date to prior year period

For the nine months ended September 30, 2015, noninterest income was $66.7 million compared to $44.6 million for the same period in 2014. The increase was primarily due to lower expense recorded for the change in FDIC loss-sharing asset, which was $11.7 million less in the current period compared to the prior year period. The increase was also driven by an increase of $5.7 million in service charges and other fees due to the increased customer base from the Intermountain acquisition and an increase of $2.8 million in other noninterest income due to both higher gains on sales of loans and increased loan prepayment fees in the current year.

Comparison of current quarter to prior year period

Total noninterest expense for the third quarter of 2015 was $64.1 million, an increase of $4.1 million, or 7% from a year earlier. The increase from the prior year period was due to additional noninterest expense stemming from the growth resulting from the Intermountain acquisition. Also contributing to the increase was an increase in net cost of other real estate owned. These increases were partially offset by lower acquisition-related expenses, which were $428 thousand during the current quarter compared to $3.2 million for the prior year period.

Comparison of current year-to-date to prior year period

For the nine months ended September 30, 2015, noninterest expense was $199.3 million, an increase of $24.1 million, or 14% from $175.1 million a year earlier. The increase from the prior-year period was due to additional ongoing noninterest expense stemming from the growth resulting from the Intermountain acquisition. Also contributing to the increase from the prior year period were acquisition-related expenses, which were $9.0 million during the nine months ended September 30, 2015 compared to $4.9 million for the prior year period.

Comparison of current quarter to prior year period

Other noninterest expense decreased $131 thousand due to lower acquisition-related expenses during the current quarter and lower expense related to investments in affordable housing projects, partially offset by general increases stemming from the acquisition of Intermountain. Acquisition-related expenses recorded to other noninterest expense during the third quarter of 2015 were $94 thousand compared to $1.9 million for the prior year period. This decrease was partially offset by higher fraud losses in the current quarter of $834 thousand compared to $266 thousand for the prior year period, included in miscellaneous other noninterest expense. The decrease in expense related to investments in affordable housing projects was due to the adoption of ASU 2014-01 Accounting for Investments in Qualified Affordable Housing Projects. The expense related to investments in affordable housing projects is now recorded to provision for income taxes in the consolidated statements of income. For additional information, see Note 1 to the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” in our 2014 Annual Report on Form 10-K.

Comparison of current year-to-date to prior year period

Other noninterest expense increased $2.2 million due to additional ongoing noninterest expense stemming from the growth resulting from the Intermountain acquisition, partially offset by lower acquisition-related expenses and expense related to investments in affordable housing projects related to the adoption of ASU 2014-01 discussed above. Acquisition-related expenses recorded to other noninterest expense during the nine months ended September 30, 2015 were $930 thousand compared to $2.0 million for the prior year period.

FDIC Acquired Loan Accounting

Net income was positively affected by the pre-tax earnings impact of the FDIC acquired loan portfolios for the current quarter and year-to-date periods, but was negatively affected by the pre-tax earnings impact of the FDIC acquired loan portfolios during the prior year periods. The negative effect of the FDIC acquired loan portfolios in the prior year period was primarily due to greater amortization of the FDIC loss-sharing asset recorded in the prior year period. With the recent expiration of our two largest FDIC loss-sharing agreements, the amortization of the FDIC loss-sharing asset has declined.

While the significance of the FDIC acquired loan accounting has diminished over time, the following table illustrates the impact to earnings associated with the Company’s FDIC acquired loan portfolios for the periods indicated:

Income Taxes

We recorded an income tax provision of $11.5 million for the third quarter of 2015, compared to a provision of $9.6 million for the same period in 2014. For the nine months ended September 30, 2015 and 2014, we recorded an income tax provision of $32.2 million and $27.0 million, respectively, with an effective tax rate of 31% and 30%, respectively. Our effective tax rate remains lower than the statutory tax rate due to the amount of tax-exempt municipal securities held in the investment portfolio and tax-exempt earnings on bank owned life insurance. For additional information, please refer to the Company’s annual report on Form 10-K for the year ended December 31, 2014.

FINANCIAL CONDITION

Total assets were $8.76 billion as of September 30, 2015, an increase of $177.1 million from $8.58 billion at December 31, 2014. The increase was due to increases in loans and securities available for sale. The increase in loans was due to significant originations during the year. Total liabilities were $7.50 billion as of September 30, 2015, an increase of $151.2 million from $7.35 billion at December 31, 2014. The increase was primarily due to an increase in deposits, partially offset by decreases in Federal Home Loan Bank advances and securities sold under agreements to repurchase.

Investment Securities

At September 30, 2015, the Company held investment securities totaling $2.03 billion compared to $2.10 billion at December 31, 2014. All of our securities are classified as available for sale and carried at fair value. The decrease in the investment securities portfolio from year-end is due to $285.8 million in principal payments, maturities and sales and $15.3 million in premium amortization, partially offset by $218.7 million in purchases and a $11.5 million increase in the net

50

unrealized gain of securities in the portfolio. The average duration of our investment portfolio was approximately 3 years and 9 months at September 30, 2015. This duration takes into account calls, where appropriate, and consensus prepayment speeds.

The investment securities are used by the Company as a component of its balance sheet management strategies. From time-to-time, securities may be sold to reposition the portfolio in response to strategies developed by the Company’s asset liability committee. In accordance with our investment strategy, management monitors market conditions with a view to realize gains on its available for sale securities portfolio when prudent.

The Company performs a quarterly assessment of the debt and equity securities in its investment portfolio that have an unrealized loss to determine whether the decline in the fair value of these securities below their amortized cost basis is other-than-temporary. Impairment is considered other-than-temporary when it becomes probable that the Company will be unable to recover the entire amortized cost basis of its investment. The Company’s impairment assessment takes into consideration factors such as the length of time and the extent to which the market value has been less than cost, defaults or deferrals of scheduled interest or principal, external credit ratings and recent downgrades, internal assessment of credit quality, and whether the Company intends to sell the security and whether it is more likely than not it will be required to sell the security prior to recovery of its amortized cost basis. If a decline in fair value is judged to be other-than-temporary, the cost basis of the individual security is written down to fair value which then becomes the new cost basis. The new cost basis is not adjusted for subsequent recoveries in fair value.

When there are credit losses associated with an impaired debt security and the Company does not have the intent to sell the security and it is more likely than not that it will not have to sell the security before recovery of its cost basis, the Company will separate the amount of the impairment into the amount that is credit-related and the amount related to non-credit factors. The credit-related impairment is recognized in earnings and the non-credit-related impairment is recognized in accumulated other comprehensive income.

At September 30, 2015, the market value of securities available for sale had a net unrealized gain of $22.7 million compared to a net unrealized gain of $11.2 million at December 31, 2014. The change in valuation was the result of fluctuations in market interest rates subsequent to purchase. At September 30, 2015, the Company had $464.1 million of investment securities with gross unrealized losses of $6.4 million; however, we did not consider these investment securities to be other-than-temporarily impaired.

The following table sets forth our securities portfolio by type for the dates indicated:

	September 30, 2015		December 31, 2014

Credit Risk Management

The extension of credit in the form of loans or other credit substitutes to individuals and businesses is one of our principal commerce activities. Our policies, applicable laws, and regulations require risk analysis as well as ongoing portfolio and credit management. We manage our credit risk through lending limit constraints, credit review, approval policies, and extensive, ongoing internal monitoring. We also manage credit risk through diversification of the loan portfolio by type of loan, type of industry and type of borrower and by limiting the aggregation of debt to a single borrower.

In analyzing our existing portfolio, we review our consumer and residential loan portfolios by their performance as a pool of loans, since no single loan is individually significant or judged by its risk rating, size or potential risk of loss. In contrast, the

51

monitoring process for the commercial business, real estate construction, and commercial real estate portfolios includes periodic reviews of individual loans with risk ratings assigned to each loan and performance judged on a loan-by-loan basis.

We review these loans to assess the ability of our borrowers to service all interest and principal obligations and, as a result, the risk rating may be adjusted accordingly. In the event that full collection of principal and interest is not reasonably assured, the loan is appropriately downgraded and, if warranted, placed on nonaccrual status even though the loan may be current as to principal and interest payments. Additionally, we assess whether an impairment of a loan warrants specific reserves or a write-down of the loan. For additional discussion on our methodology in managing credit risk within our loan portfolio, see the following: “Allowance for Loan and Lease Losses” section in this Management’s Discussion and Analysis and Note 1 to the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” of the Company’s 2014 Annual Report on Form 10-K.

Loan policies, credit quality criteria, portfolio guidelines and other controls are established under the guidance of our Chief Credit Officer and approved, as appropriate, by the board of directors. Credit Administration, together with the management loan committee, has the responsibility for administering the credit approval process. As another part of its control process, we use an internal credit review and examination function to provide reasonable assurance that loans and commitments are made and maintained as prescribed by our credit policies. This includes a review of documentation when the loan is initially extended and subsequent examination to ensure continued performance and proper risk assessment.

Loan Portfolio Analysis

Our wholly owned banking subsidiary Columbia State Bank (“Columbia Bank” or the “Bank”) is a full service commercial bank, which originates a wide variety of loans, and focuses its lending efforts on originating commercial business and commercial real estate loans.

The following table sets forth the Company’s loan portfolio by type of loan for the dates indicated:

	September 30, 2015			% of Total		December 31, 2014			% of Total

Loans held for sale	$	6,637				$	1,116

Total loans increased $301.1 million from year-end 2014 due to significant originations during the year. The loan portfolio continues to be diversified, with the intent to mitigate risk by minimizing concentration in any one segment. The $45.4 million in unearned income recorded at September 30, 2015 was comprised of $36.0 million in discount on acquired loans and $9.4 million in deferred loan fees. The $59.4 million in unearned income recorded at December 31, 2014 consisted of $50.8 million in discount on acquired loans and $8.6 million in deferred loan fees.

Commercial Loans: We are committed to providing competitive commercial lending in our primary market areas. Management expects a continued focus within its commercial lending products and to emphasize, in particular, relationship banking with businesses and business owners.

Real Estate Loans: One-to-four family residential loans are secured by properties located within our primary market areas and, typically, have loan-to-value ratios of 80% or lower at origination. Our underwriting standards for commercial and multifamily residential loans generally require that the loan-to-value ratio for these loans not exceed 75% of appraised value, cost, or discounted cash flow value, as appropriate, and that commercial properties maintain debt coverage ratios (net operating income divided by annual debt servicing) of 1.2 or better. However, underwriting standards can be influenced by competition and other factors. We endeavor to maintain the highest practical underwriting standards while balancing the need to remain competitive in our lending practices.

Real Estate Construction Loans: We originate a variety of real estate construction loans. Underwriting guidelines for these loans vary by loan type but include loan-to-value limits, term limits and loan advance limits, as applicable. Our underwriting guidelines for commercial and multifamily residential real estate construction loans generally require that the loan-to-value ratio not exceed 75% and stabilized debt coverage ratios (net operating income divided by annual debt servicing) of 1.2 or better. As noted above, underwriting standards can be influenced by competition and other factors. However, we endeavor to maintain the highest practical underwriting standards while balancing the need to remain competitive in our lending practices.

Consumer Loans: Consumer loans include automobile loans, boat and recreational vehicle financing, home equity and home improvement loans and miscellaneous personal loans.

Foreign Loans: The Company has no material foreign activities. Substantially all of the Company’s loans and unfunded commitments are geographically concentrated in its service areas within the states of Washington, Oregon and Idaho.

Purchased Credit Impaired Loans: PCI loans are comprised of loans and loan commitments acquired in connection with the 2011 FDIC-assisted acquisitions of First Heritage Bank and Summit Bank, as well as the 2010 FDIC-assisted acquisitions of Columbia River Bank and American Marine Bank. PCI loans are generally accounted for under ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310-30”).

For additional information on our loan portfolio, including amounts pledged as collateral on borrowings, see Note 5 to the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

Nonperforming Assets

Nonperforming assets consist of: (i) nonaccrual loans, which generally are loans placed on a nonaccrual basis when the loan becomes past due 90 days or when there are otherwise serious doubts about the collectability of principal or interest within the existing terms of the loan, (ii) OREO; and (iii) other personal property owned, if applicable.

Nonaccrual loans: The Consolidated Financial Statements are prepared according to the accrual basis of accounting. This includes the recognition of interest income on the loan portfolio, unless a loan is placed on nonaccrual status, which occurs when there are serious doubts about the collectability of principal or interest. Our policy is generally to discontinue the accrual of interest on all loans past due 90 days or more and place them on nonaccrual status. Loans accounted for under ASC 310-30 are generally considered accruing and performing as the loans accrete interest income over the estimated lives of the loans when cash flows are reasonably estimable. Accordingly, PCI loans accounted for under ASC 310-30 that are contractually past due are still considered to be accruing and performing loans.

53

Nonperforming assets decreased $15.0 million during the nine months ended September 30, 2015 as a result of a $12.3 decline in nonaccrual loans and a $2.7 million decline in OREO, primarily due to OREO sales.

Other Real Estate Owned: During the nine months ended September 30, 2015, OREO decreased $2.7 million. The following table sets forth activity in OREO for the periods indicated:

Allowance for Loan and Lease Losses

Loans, excluding Purchased Credit Impaired Loans

We maintain an ALLL to absorb losses inherent in the loan portfolio. The size of the ALLL is determined through quarterly assessments of the probable estimated losses in the loan portfolio. Our methodology for making such assessments and determining the adequacy of the ALLL includes the following key elements:

1. General valuation allowance consistent with the Contingencies topic of the FASB ASC.

2. Classified loss reserves on specific relationships. Specific allowances for identified problem loans are determined in accordance with the Receivables topic of the FASB ASC.

3. The unallocated allowance provides for other factors inherent in our loan portfolio that may not have been contemplated in the general and specific components of the allowance. This unallocated amount generally comprises less than 5% of the allowance. The unallocated amount is reviewed quarterly based on trends in credit losses, the results of credit reviews and overall economic trends.

On a quarterly basis, our Chief Credit Officer reviews with executive management and the board of directors the various additional factors that management considers when determining the adequacy of the ALLL, including economic and business condition reviews. Factors which influenced management’s judgment in determining the amount of the additions to the ALLL charged to operating expense include the following as of the applicable balance sheet dates:

• Existing general economic and business conditions affecting our market place

• Credit quality trends

• Historical loss experience

• Seasoning of the loan portfolio

• Bank regulatory examination results

• Findings of internal credit examiners

• Duration of current business cycle

• Specific loss estimates for problem loans

The ALLL is increased by provisions for loan and lease losses (“provision”) charged to expense, and is reduced by loans charged off, net of recoveries or recapture of previous provision. While we believe the best information available is used by us to determine the ALLL, changes in market conditions could result in adjustments to the ALLL, affecting net income, if circumstances differ from the assumptions used in determining the ALLL.

In addition to the ALLL, we maintain an allowance for unfunded commitments and letters of credit. We report this allowance as a liability on our Consolidated Balance Sheet. We determine this amount using estimates of the probability of the ultimate funding and losses related to those credit exposures. This methodology is similar to the methodology we use for determining the adequacy of our ALLL. For additional information on our allowance for unfunded commitments and letters of credit, see Note 6 to the Consolidated Financial Statements presented elsewhere in this report.

Purchased Credit Impaired Loans

PCI loans are accounted for under ASC 310-30 and initially measured at fair value based on expected future cash flows over the life of the loans. PCI loans that have common risk characteristics are aggregated into pools. The Company re-measures contractual and expected loan cash flows, at the pool-level, on a quarterly basis. If, due to credit deterioration, the present value of expected cash flows, as periodically re-measured, is less than the carrying value of the loan pool, the Company adjusts the carrying value of the loan pool to the lower amount by adjusting the ALLL with a charge to earnings through the provision for loan losses. If the present value of expected cash flows is greater than the carrying value of the loan pool, the Company adjusts the carrying value of the loan pool to a higher amount by recapturing previously recorded allowance for loan losses, if any.

At September 30, 2015, our ALLL was $69.0 million, or 1.20% of total loans (excluding loans held for sale). This compares with an ALLL of $69.6 million, or 1.28% of total loans (excluding loans held for sale) at December 31, 2014 and an ALLL of $67.9 million or 1.41% of total loans (excluding loans held for sale) at September 30, 2014.

FDIC Loss-sharing Asset

The Company has elected to account for amounts receivable under loss-sharing agreements with the FDIC as an indemnification asset in accordance with the Business Combinations topic of the FASB ASC. The FDIC indemnification asset is initially recorded at fair value, based on the discounted expected future cash flows under the loss-sharing agreements.

Subsequent to initial recognition, the FDIC indemnification asset is reviewed quarterly and adjusted for any changes in expected cash flows. These adjustments are measured on the same basis as the related covered loans. Any decrease in expected cash flows on the covered loans due to an increase in expected credit losses will increase the FDIC indemnification asset and any increase in expected future cash flows on the covered loans due to a decrease in expected credit losses will decrease the FDIC indemnification asset. Changes in the estimated cash flows on covered assets that are immediately recognized in income generally result in a similar immediate adjustment to the loss-sharing asset while changes in expected cash flows on covered assets that are accounted for as an adjustment to yield generally result in adjustments to the amortization or accretion rate for the loss-sharing asset. Increases and decreases to the FDIC loss-sharing asset are recorded as adjustments to noninterest income.

At September 30, 2015, the FDIC loss-sharing asset was $8.1 million, which was comprised of a $6.7 million FDIC indemnification asset and a $1.4 million FDIC receivable.

For additional information on the FDIC loss-sharing asset, please see Note 8 to the Consolidated Financial Statements presented elsewhere in this report.

Liquidity and Sources of Funds

Our primary sources of funds are customer deposits. Additionally, we utilize advances from the FHLB of Des Moines (“Des Moines Bank”), the Federal Reserve Bank of San Francisco, and wholesale and retail repurchase agreements to supplement our funding needs. These funds, together with loan repayments, loan sales, retained earnings, equity and other borrowed funds are used to make loans, to acquire securities and other assets, and to fund continuing operations.

In addition, we have a shelf registration statement on file with the Securities and Exchange Commission registering an unlimited amount of any combination of debt or equity securities, depositary shares, purchase contracts, units and warrants in one or more offerings. Specific information regarding the terms of and the securities being offered will be provided at the time of any offering. Proceeds from any future offerings are expected to be used for general corporate purposes, including, but not limited to, the repayment of debt, repurchasing or redeeming outstanding securities, working capital, funding future acquisitions or other purposes identified at the time of any offering.

During the second quarter of 2015, the FHLB of Seattle (“Seattle Bank”) merged with and into the Des Moines Bank. As a result of the merger, certain of Columbia’s shares of Seattle Bank capital stock were converted into shares of Des Moines Bank capital stock; excess Seattle Bank shares were redeemed for cash. The balance of Columbia’s FHLB stock decreased from

57

$33.4 million at December 31, 2014 to $10.2 million at September 30, 2015, reflecting, in part, the redemption of excess Seattle Bank shares. The balance of Columbia’s FHLB stock will continue to fluctuate based upon Columbia’s borrowing activity with the Des Moines Bank.

Deposit Activities

Our deposit products include a wide variety of transaction accounts, savings accounts and time deposit accounts. Core deposits (demand deposit, savings, money market accounts and certificates of deposit less than $100,000) increased $366.3 million since year-end 2014. During the current year, as part of a product migration to our new deposit account product line, a substantial portion of our interest-bearing deposits which were typically bearing a nominal interest rate were migrated to noninterest-bearing deposit products. This migration resulted in a decrease in interest-bearing demand deposit balances and an increase in noninterest-bearing deposit balances during the current year.

We have established a branch system to serve our consumer and business depositors. In addition, management’s strategy for funding asset growth is to make use of brokered and other wholesale deposits on an as-needed basis. The Company participates in the Certificate of Deposit Account Registry Service (CDARS^®) program. CDARS^® is a network that allows participating banks to offer extended FDIC deposit insurance coverage on time deposits. The Company also participates in a similar program to offer extended FDIC deposit insurance coverage on money market accounts. These extended deposit insurance programs are generally available only to existing customers and are not used as a means of generating additional liquidity. At September 30, 2015, CDARS^® deposits and brokered money market deposits were $144.2 million, or 2% of total deposits, compared to $101.8 million at year-end 2014. The brokered deposits have varied maturities.

The following table sets forth the Company’s deposit base by type of product for the dates indicated:

	September 30, 2015				December 31, 2014
	Balance		% of Total		Balance		% of Total
	(dollars in thousands)
Core deposits:

Premium resulting from acquisition date fair value adjustment	381				933
Total deposits	$	7,314,805			$	6,924,722

Borrowings

We rely on FHLB advances and FRB borrowings as another source of both short and long-term funding. FHLB advances and FRB borrowings are secured by bonds within our investment portfolio, and residential, commercial and commercial real estate loans. At September 30, 2015, we had FHLB advances of $6.5 million compared to $216.6 million at December 31, 2014.

We also utilize wholesale and retail repurchase agreements as a supplement to our funding sources. Our wholesale repurchase agreements are secured by mortgage-backed securities. At September 30, 2015 and December 31, 2014, we had term repurchase agreements of $25.0 million, which mature in 2018, and deposit customer sweep-related repurchase agreements of $48.2 million and $80.1 million, respectively, which mature on a daily basis. Management anticipates we will continue to rely on FHLB advances, FRB borrowings, and wholesale and retail repurchase agreements in the future and we will use those funds primarily to make loans and purchase securities.

58

Contractual Obligations, Commitments & Off-Balance Sheet Arrangements

We are party to many contractual financial obligations, including repayment of borrowings, operating and equipment lease payments, off-balance sheet commitments to extend credit and investments in affordable housing partnerships. At September 30, 2015, we had commitments to extend credit of $1.89 billion compared to $1.62 billion at December 31, 2014.

Capital Resources

Shareholders’ equity at September 30, 2015 was $1.25 billion, an increase from $1.23 billion at December 31, 2014. Shareholders’ equity was 14% of total period-end assets at September 30, 2015 and December 31, 2014.

Capital Ratios: Basel III capital requirements became effective on January 1, 2015. The new capital requirements, among other things, (i) introduce a new capital measure called “Common Equity Tier 1,” or CET1, (ii) specify that Tier 1 capital consists of CET1 and “Additional Tier 1 capital” instruments meeting specified requirements, (iii) define CET1 narrowly by requiring that most deductions/adjustments to regulatory capital measures be made to CET1 and not to the other components of capital and (iv) expand the scope of the deductions/adjustments to capital as compared to existing regulations. Under the requirements that are now effective, the minimum capital ratios are now (i) 4.5% CET1 to risk-weighted assets, (ii) 6% Tier 1 capital to risk-weighted assets, (iii) 8% total capital to risk-weighted assets and (iv) 4% Tier 1 leverage. The Company and the Bank have made the one-time election to opt-out of including accumulated other comprehensive income items in regulatory capital calculations.

FDIC regulations set forth the qualifications necessary for a bank to be classified as “well capitalized,” primarily for assignment of FDIC insurance premium rates. To qualify as “well capitalized,” banks must have a CET1 risk-adjusted capital ratio of 6.5%, a Tier I risk-adjusted capital ratio of at least 8%, a total risk-adjusted capital ratio of at least 10% and a leverage ratio of at least 5%. Failure to qualify as “well capitalized” can negatively impact a bank’s ability to expand and to engage in certain activities.

The Company and its banking subsidiary qualify as “well-capitalized” at September 30, 2015. The following table presents the regulatory standards for adequately capitalized and well-capitalized institutions and the capital ratios for the Company and its banking subsidiary at September 30, 2015:

	Company		Columbia Bank		Requirements
	September 30, 2015		September 30, 2015		Adequately capitalized		Well- Capitalized
Common equity tier 1 (CET1) risk-based capital ratio	12.18	%	11.99	%	4.50	%	6.50	%
Tier 1 risk-based capital ratio	12.18	%	11.99	%	6.00	%	8.00	%
Total risk-based capital ratio	13.22	%	13.02	%	8.00	%	10.00	%
Leverage ratio	10.21	%	10.06	%	4.00	%	5.00	%

For additional information concerning the new Basel III capital requirements, including information regarding those requirements when fully phased in, see “Business-Regulatory Capital Requirements” in our 2014 Form 10-K. See Note 24, Regulatory Capital Requirements, in Item 8 of our 2014 Form 10-K for additional details related to our capital ratios as of December 31, 2014 based on capital requirements then in effect.

Non-GAAP Financial Measures

The Company considers operating net interest margin (tax equivalent) to be an important measurement as it more closely reflects the ongoing operating performance of the Company. Additionally, presentation of the operating net interest margin allows readers to compare certain aspects of the Company’s net interest margin to other organizations. Despite the importance of the operating net interest margin (tax equivalent) to the Company, there is no standardized definition for it and, as a result, the Company’s calculations may not be comparable with other organizations. The Company encourages readers to consider its consolidated financial statements in their entirety and not to rely on any single financial measure.

The following table reconciles the Company’s calculation of the operating net interest margin (tax equivalent) to the net interest margin (tax equivalent) for the periods indicated:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2015			2014			2015			2014
Operating net interest margin non-GAAP reconciliation:	(dollars in thousands)
Net interest income (tax equivalent) (1)	$	84,254		$	78,232		$	250,218		$	231,089

Incremental accretion income on FDIC purchased credit impaired loans	(2,082		)	(4,205		)	(6,896		)	(16,428		)
Incremental accretion income on other FDIC acquired loans	(34		)	(175		)	(166		)	(474		)

__________

(1) Tax-exempt interest income has been adjusted to a tax equivalent basis. The amount of such adjustment was an addition to net interest income of $2.6 million and $2.0 million for the three months ended September 30, 2015 and 2014, respectively, and an addition to net interest income of $7.2 million and $5.8 million for the nine months ended September 30, 2015 and 2014, respectively.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

A number of measures are used to monitor and manage interest rate risk, including income simulations and interest sensitivity (gap) analysis. An income simulation model is the primary tool used to assess the direction and magnitude of changes in net interest income resulting from changes in interest rates. Basic assumptions in the model include prepayment speeds on mortgage-related assets, cash flows and maturities of other investment securities, loan and deposit volumes and pricing. These assumptions are inherently subjective and, as a result, the model cannot precisely estimate net interest income or precisely predict the impact of higher or lower interest rates on net interest income. Actual results will differ from simulated results due to timing, magnitude and frequency of interest rate changes and changes in market conditions and management strategies, among other factors. At September 30, 2015, based on the measures used to monitor and manage interest rate risk, there has not been a material change in the Company’s interest rate risk since December 31, 2014. For additional information, refer to Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s 2014 Annual Report on Form 10-K.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

An evaluation was carried out under the supervision and with the participation of the Company’s management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934). Based on that evaluation, the CEO and CFO have concluded that as of the end of the period covered by this report, our disclosure controls and procedures are effective in ensuring that the information required to be disclosed by us in the reports we file or submit under the Securities Exchange Act of 1934 is (i) accumulated and communicated to our management (including the CEO and CFO) to allow timely decisions regarding required disclosure, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in Internal Control Over Financial Reporting

There was no change in our internal controls over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

On October 30, 2015, Columbia State Bank (the “Bank”) entered into split dollar life insurance agreements (the “Agreements”) with Melanie J. Dressel, President and Chief Executive Officer of the Company and the Bank. The Agreements provide Ms. Dressel’s beneficiaries with benefits comparable to those provided to the beneficiaries of the Bank’s other senior officers in the event of death while employed by the Bank or, for Ms. Dressel, while serving on the Bank’s board of directors.

The Bank is the owner of the life insurance policies and is responsible for paying the premiums due under such policies. Under the Agreements, the amount of the death benefit payable to Ms. Dressel’s beneficiaries is equal to three times her then-current base salary and approximately ten times the projected benefit at normal retirement age of her Supplemental Executive Retirement Plan, or SERP, minus the value of other life insurance policies owned by Ms. Dressel and the Bank. Ms. Dressel may request an acceleration of these benefits in the event of terminal or chronic illness.

The foregoing description of the Agreements is not complete and is qualified in its entirety by reference to the full text of the Agreements that are filed as Exhibits 10.1 and 10.2 hereto and incorporated by reference herein.

Provided Insured’s right to receive benefits under this Agreement has not terminated pursuant to the provisions of Paragraph 9 herein, and provided the Policy(ies) provides for such option through an accelerated benefit or living benefit rider (i.e., generally requiring that the Insured is either terminally or chronically ill), Insured shall have the right to request, in writing, the full amount to which he is entitled under this Agreement, and subject to any further limitation on dollar amounts imposed by the Policy(ies). Any Accelerated Benefit paid to the Insured hereunder shall be deducted from any amounts to which Insured or his Beneficiary is (or may be) entitled pursuant to the provisions of Paragraph 6 above. Neither the Bank nor Corrigan & Company (PFIS) make any representations or warranties about the tax consequences of such a request for accelerated or living benefits. Should the Insured request and receive an Accelerated Benefit in an amount equal to the amount he is (or may be) entitled to receive pursuant to the terms of Paragraph 7 above, then this Agreement shall terminate as stated in Paragraph 9, and neither the Insured nor Insured’s Beneficiary shall be entitled to receive any further amounts under this Agreement.

In addition, and subject to the forgoing, at all times prior to the Insured’s death, the Bank shall be entitled to an amount equal to the Policy(ies)’s cash value, as that term is defined in the Policy(ies) contract, less any Policy loans, accelerated benefits and unpaid interest or cash withdrawals previously incurred by the Bank and any applicable surrender charges. Such cash value shall be determined as of the date of surrender or death as the case may be.

8. RIGHTS OF PARTIES WHERE POLICY(IES) ENDOWMENT OR ANNUITY ELECTION EXISTS.

In the event the Policy(ies) involves an endowment or annuity element, the Bank’s right and interest in any endowment proceeds or annuity benefits, on expiration of the deferment period, shall be determined under the provisions of this Agreement by regarding such endowment proceeds or the commuted value of such annuity benefits as the Policy’s cash value. Such endowment proceeds or annuity benefits shall be considered to be like death proceeds for the purposes of division under this Agreement.

9. TERMINATION OF AGREEMENT.

This Agreement shall terminate upon Insured’s Separation From Service, upon the mutual written agreement of the Bank and the Insured, or upon distribution of the death benefit proceeds in accordance with Paragraph 6 above. In addition, this Agreement shall also terminate in the event Insured requests and receives an

5

Accelerated Benefit in an amount equal to the amount he is (or may be) entitled to receive pursuant to the provisions of Paragraph 7 above.

10. INSURED’S OR ASSIGNEE’S ASSIGNMENT RIGHTS.

The Insured may not, without the written consent of the Bank, assign to any individual, trust or other organization, any right, title or interest in the subject Policy(ies) nor any rights, options, privileges or duties created under this Agreement.

11. AGREEMENT BINDING UPON THE PARTIES.

This Agreement shall bind the Insured and the Bank, their heirs, successors, personal representatives and assigns.

12. ADMINISTRATIVE AND CLAIMS PROVISIONS.

The following provisions are part of this Agreement and are intended to meet the requirements of ERISA (when required):

A.    Named Fiduciary and Plan Administrator.

The Named Fiduciary and Plan Administrator (hereinafter “Administrator) of this Endorsement Method Split Dollar Agreement shall be the Board of Directors of the Bank. The Administrator may designate a replacement Administrator at any time, or may delegate to others certain responsibilities, including the employment of advisors and the delegation of any ministerial duties to qualified individuals.

B. Dispute Over Benefits.

In the event a dispute arises over the benefits under this plan and benefits are not paid to the Insured (or to the Insured’s beneficiary[ies], if applicable) and such Claimants feel they are entitled to receive such benefits, then a written claim must be made to the Administrator named above in accordance with the following procedures:

(i) Written Claim. Claimant may file a written request for such benefit to the Administrator.

(ii) Claim Decision. Upon receipt of such claim, the Administrator shall respond to such Claimant within ninety (90) days after receiving the claim. If the Administrator determines that special circumstances require additional time for processing the claim, the Administrator can extend the response period by an additional ninety (90) days for reasonable cause by notifying Claimant in writing, prior to the end

6

of the initial ninety (90) day period, that an additional period is required. The notice of extension must set forth the special circumstances and the date by which the Administrator expects to render its decision.

If the claim is denied in whole or in part, the Administrator shall notify Claimant in writing of such denial. The Administrator shall write the notification in a manner calculated to be understood by Claimant. The notification shall set forth:

(a) The specific reasons for the denial;

(b) The specific reference to pertinent provisions of the Agreement on which the denial is based;

(c) A description of any additional information or material necessary for Claimant to perfect the claim and an explanation of why such material or information is necessary;

(d) Appropriate information as to the steps to be taken if Claimant wishes to submit the claim for review and the time limits applicable to such procedures; and

(e) A statement of Claimant’s right to bring a civil action under ERISA Section 502(a) following an adverse benefit determination on review.

(iii). Request for Review. Within sixty (60) days after receiving notice from the Administrator that a claim has been denied (in part or all of the claim), then Claimant (or their duly authorized representative) may file with the Administrator, a written request for a review of the denial of the claim.

Claimant (or his duly authorized representative) shall then have the opportunity to submit written comments, documents, records and other information relating to the claim. The Administrator shall also provide Claimant, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant (as defined in applicable ERISA regulations) to Claimant’s claim for benefits.

(iv). Decision on Review. The Administrator shall respond in writing to such Claimant within sixty (60) days after receiving the request for review. If the Administrator determines that special circumstances require an extension of time for processing the claim, written notice of the extension shall be furnished to Claimant prior to the termination of the initial sixty (60) day period. In no event shall such extension exceed a period of sixty (60) days from the end of the initial period. The notice of extension must set forth the special circumstances

7

requiring an extension of time and the date by which the Administrator expects to render its decision.

In considering the review, the Administrator shall take into account all materials and information Claimant submits relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination.

The Administrator shall notify Claimant in writing of its decision on review. The Administrator shall write the notification in a manner calculated to be understood by Claimant. The notification shall set forth:

(a) The specific reasons for the denial;

(b) A reference to the specific provisions of the Agreement on which the denial is based;

(c) A statement that Claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant (as defined in applicable ERISA regulations) to Claimant’s claim for benefits; and

(d) A statement of Claimant’s right to bring a civil action under ERISA Section 502(a).

(v) Special Timing and Rules for Disability Claims. In the event a claim above is a claim for disability benefits, then the applicable time periods for notifying Claimants regarding benefit determinations shall be reduced as required by 29 CFR 2560.503-1. Thus, the Administrator shall provide notice to Claimant, within a reasonable period of time, but not later than forty five (45) days after receipt of the claim. This period may be extended by up to thirty (30) days, provided that the Administrator both determines that such an extension is necessary due to matters beyond the control of the plan and notifies Claimant, prior to the expiration of the initial forty five (45) day period, of the circumstances requiring the extension of time and the date by which the plan expects to render a decision. If, prior to the end of the first thirty (30) day extension period, the Administrator determines that, due to matters beyond the control of the plan, a decision cannot be rendered within that extension period, the period for making the determination may be extended for up to an additional thirty (30) days, provided that the Administrator notifies Claimant, prior to the expiration of the first thirty (30) day extension period, of the circumstances requiring the extension and the date as of which the plan expects to render a decision. In the case of any extension under this paragraph, the notice of extension shall specifically explain the standards on which entitlement to a benefit

8

is based, the unresolved issues that prevent a decision on the claim, and the additional information needed to resolve those issues, and Claimant shall be afforded at least forty five (45) days within which to provide the specified information. In addition to complying with such timing rules, a claim under this paragraph shall comply with all procedural requirements under ERISA.

13.    GENDER.

Whenever in this Agreement words are used in the masculine, feminine or neuter gender, they shall be read and construed as in the masculine, feminine or neuter gender, whenever they should so apply.

14. INSURANCE COMPANY NOT A PARTY TO THIS AGREEMENT.

The Insurer shall not be deemed a party to this Agreement, but will respect the rights of the parties as herein developed upon receiving an executed copy of this Agreement. Payment or other performance in accordance with the Policy(ies) provisions shall fully discharge the Insurer from any and all liability.

15.    SEVERABILITY AND INTERPRETATION.

If a provision of this Agreement is held to be invalid or unenforceable, the remaining provisions shall nonetheless be enforceable according to their terms. Further, in the event that any provision is held to be overbroad as written such provision shall be deemed amended to narrow its application to the extent necessary to make the provision enforceable according to law and enforced as amended.

16.    APPLICABLE LAW.

The laws of the State of Washington shall govern the validity and interpretation of this Agreement.

17. EFFECT OF THE LIFE INSURANCE POLICY’S CONTESTABILITY CLAUSES.

The parties herein understand and agree that the payment of the benefits provided herein are subject to the Policy’s(ies’) suicide and contestability clauses and other such clauses, and if such clauses preclude the Insurer from paying the full death

9

proceeds, then, in such event, no death benefits of whatever nature shall be payable to Insured’s (or Insured’s Assignee’s) Beneficiary under this Endorsement Method Split Dollar Agreement.

This Agreement shall be effective as of the date first set forth above.

The collateral utilized for the Company’s repurchase agreements is subject to market fluctuations as well as prepayments of principal.

The pledged collateral related to the Company’s term wholesale repurchase agreement, which matures in 2018, is monitored on a monthly basis and additional capital is pledged when necessary. The pledged collateral related to the Company’s sweep repurchase agreements, which mature on a daily basis, is monitored on a daily basis as the underlying sweep accounts can have daily transaction activity and the amount of pledged collateral is adjusted as necessary.

Earnings per Common Share

Earnings Per Share [Abstract]

Earnings Per Common Share

Earnings per Common Share

The Company applies the two-class method of computing basic and diluted EPS. Under the two-class method, EPS is determined for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. The Company issues restricted shares under share-based compensation plans and preferred shares which qualify as participating securities.

The following table sets forth the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2015 and 2014:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,

Basic earnings per common share	$	0.45	$	0.41	$	1.25	$	1.20
Diluted EPS:
Earnings allocated to common shareholders (1)	$	25,439	$	21,325	$	71,188	$	61,940
Weighted average common shares outstanding	57,051		52,112		57,007		51,772
Dilutive effect of equity awards	13		404		14		707
Weighted average diluted common shares outstanding	57,064		52,516		57,021		52,479
Diluted earnings per common share	$	0.45	$	0.41	$	1.25	$	1.18
Potentially dilutive share options that were not included in the computation of diluted EPS because to do so would be anti-dilutive	29		58		40		67

__________

(1) Earnings allocated to common shareholders for basic and diluted EPS may differ under the two-class method as a result of adding common stock equivalents for options and warrants to dilutive shares outstanding, which alters the ratio used to allocate earnings to common shareholders and participating securities for the purposes of calculating diluted EPS.

Business Acquisition, Supplemental Pro Forma Information [Line Items]

Business Acquisition, Pro Forma Information [Table Text Block]

For illustrative purposes only, the following table presents certain unaudited pro forma information for the nine month period ended September 30, 2014. This unaudited pro forma information was calculated as if Intermountain had been acquired as of the beginning of the year prior to the date of acquisition. The unaudited pro forma information combines the historical results of Intermountain with the Company’s consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective period. The pro forma information is not indicative of what would have occurred had the acquisition occurred as of the beginning of the year prior to the acquisition. 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 the beginning of the year prior to the date of acquisition. 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, Columbia 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.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Intangible Assets

Goodwill and Other Intangible Assets

In accordance with the Intangibles – Goodwill and Other topic of the FASB ASC, goodwill is not amortized but is reviewed for potential impairment at the reporting unit level. Management analyzes its goodwill for impairment on an annual basis on July 31 and between annual tests in certain circumstances such as material adverse changes in legal, business, regulatory and economic factors. An impairment loss is recorded to the extent that the carrying amount of goodwill exceeds its implied fair value. The Company performed an impairment assessment as of July 31, 2015 and concluded that there was no impairment.

The core deposit intangible (“CDI”) is evaluated for impairment if events and circumstances indicate a possible impairment. The CDI is amortized on an accelerated basis over an estimated life of 10 years.

The following table sets forth activity for goodwill and other intangible assets for the periods indicated:

Derivatives and Balance Sheet Offsetting

9 Months Ended

General Discussion of Derivative Instruments and Hedging Activities [Abstract]

Derivatives and Hedging Activities

Derivatives and Balance Sheet Offsetting

The Company periodically enters into certain commercial loan interest rate swap agreements in order to provide commercial loan customers the ability to convert from variable to fixed interest rates. Under these agreements, the Company enters into a variable-rate loan agreement with a customer in addition to a swap agreement. This swap agreement effectively converts the customer’s variable rate loan into a fixed rate. The Company then enters into a corresponding swap agreement with a third-party in order to offset its exposure on the variable and fixed components of the customer agreement. As the interest rate swap agreements with the customers and third parties are not designated as hedges under the Derivatives and Hedging topic of the FASB ASC, the instruments are marked to market in earnings. The notional amount of open interest rate swap agreements at September 30, 2015 and December 31, 2014 was $226.8 million and $215.6 million, respectively. During the three and nine months ended September 30, 2015, a mark-to-market loss of $6 thousand and $2 thousand, respectively was recorded to other noninterest expense. There were no earnings impacts for the three or nine month periods ending September 30, 2014.

The following table presents the fair value of derivatives not designated as hedging instruments at September 30, 2015 and December 31, 2014:

The Company is party to interest rate contracts and repurchase agreements that are subject to enforceable master netting arrangements or similar agreements. Under these agreements, the Company may have the right to net settle multiple contracts with the same counterparty. The following tables show the gross interest rate swap agreements and repurchase agreements in the consolidated balance sheets and the respective collateral received or pledged in the form of other financial instruments, which are generally marketable securities. The collateral amounts in these tables are limited to the outstanding balances of the related asset or liability. Therefore, instances of overcollateralization are not shown.

Gross amount of recognized liabilities for repurchase agreements									73,182
Amounts related to agreements not included in offsetting disclosure									$	—

The collateral utilized for the Company’s repurchase agreements is subject to market fluctuations as well as prepayments of principal. The Company monitors the risk of the fair value of its pledged collateral falling below acceptable amounts based on the type of the underlying repurchase agreement. The pledged collateral related to the Company’s term wholesale repurchase agreement, which matures in 2018, is monitored on a monthly basis and additional capital is pledged when necessary. The pledged collateral related to the Company’s sweep repurchase agreements, which mature on a daily basis, is monitored on a daily basis as the underlying sweep accounts can have daily transaction activity and the amount of pledged collateral is adjusted as necessary.

At September 30, 2015, there were 75 U.S. government agency and government-sponsored enterprise mortgage-backed securities and collateralized mortgage obligations securities in an unrealized loss position, of which 38 were in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where these investments fall within the yield curve and their individual characteristics. Because the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2015.

At September 30, 2015, there were 57 state and municipal government securities in an unrealized loss position, of which 28 were in a continuous loss position for 12 months or more. The unrealized losses on state and municipal securities were caused by interest rate changes or widening of market spreads subsequent to the purchase of the individual securities. Management monitors published credit ratings of these securities for adverse changes. As of September 30, 2015, none of the rated obligations of state and local government entities held by the Company had a below investment grade credit rating. Because the credit quality of these securities are investment grade and the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2015.

At September 30, 2015, there were six U.S. government agency and government-sponsored enterprise securities in an unrealized loss position, five of which were in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where these investments fall within the yield curve and their individual characteristics. Because the Company does not currently intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2015.

At September 30, 2015, there was one U.S. government security in an unrealized loss position which was in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where this investment falls within the yield curve and its individual characteristics. Because the Company does not currently intend to sell this security nor does the Company consider it more likely than not that it will be required to sell this security before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider this investment to be other-than-temporarily impaired at September 30, 2015.

At September 30, 2015, there was one other security in an unrealized loss position, which was in a continuous unrealized loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates and the additional risk premium investors are demanding for investment securities with these characteristics. The Company does not consider this investment to be other-than-temporarily impaired at September 30, 2015 as it has the intent and ability to hold the investment for sufficient time to allow for recovery in the market value.

On November 1, 2014, the Company completed its acquisition of Intermountain. The Company paid $131.9 million in total consideration to acquire 100% of the equity interests of Intermountain. The primary reason for the acquisition was to expand the Company’s geographic footprint into the state of Idaho, consistent with its ongoing growth strategy.

The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their fair values as of the November 1, 2014 acquisition date. Initial accounting for deferred taxes was provisionally measured as of November 1, 2014. During the current quarter, the provisionally measured deferred taxes were finalized. The resulting adjustment was a decrease in other assets of $225 thousand and a corresponding increase in goodwill of $225 thousand. There was no impact to earnings as a result of these adjustments. These adjustments were recorded as current period adjustments pursuant to the Company’s early adoption of ASU 2015-16. The application of the acquisition method of accounting resulted in recognition of goodwill of $38.8 million and a core deposit intangible of $10.9 million, or 1.75% of core deposits. The goodwill represents the excess purchase price over the fair value of the net assets acquired. The goodwill is not deductible for income tax purposes.

The table below summarizes the amounts recognized as of the acquisition date for each major class of assets acquired and liabilities assumed:

	November 1, 2014
	(in thousands)
Purchase price as of November 1, 2014	$	131,935
Recognized amounts of identifiable assets acquired and (liabilities assumed), at fair value:
Cash and cash equivalents	$	47,283
Investment securities	299,458
Federal Home Loan Bank stock	2,124
Acquired loans	502,595
Interest receivable	4,656

Core deposit intangible	10,900
Other assets	35,128
Deposits	(736,795		)

Securities sold under agreements to repurchase	(59,043		)
Other liabilities	(13,725		)
Total fair value of identifiable net assets	93,125
Goodwill	$	38,810

See Note 9, Goodwill and Other Intangible Assets, for further discussion of the accounting for goodwill and other intangible assets.

The operating results of the Company reported herein include the operating results produced by the acquired assets and assumed liabilities for the period January 1, 2015 to September 30, 2015. Disclosure of the amount of Intermountain’s revenue and net income (excluding integration costs) included in Columbia’s consolidated income statement is impracticable due to the integration of the operations and accounting for this acquisition.

For illustrative purposes only, the following table presents certain unaudited pro forma information for the nine month period ended September 30, 2014. This unaudited pro forma information was calculated as if Intermountain had been acquired as of the beginning of the year prior to the date of acquisition. The unaudited pro forma information combines the historical results of Intermountain with the Company’s consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective period. The pro forma information is not indicative of what would have occurred had the acquisition occurred as of the beginning of the year prior to the acquisition. 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 the beginning of the year prior to the date of acquisition. 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, Columbia 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 connection with the Intermountain acquisition, Columbia recognized $428 thousand and $9.0 million in acquisition-related expenses for the three and nine month periods ended September 30, 2015, respectively, and recognized $459 thousand in acquisition-related expenses for the three and nine month periods ended September 30, 2014. In addition, related to the acquisition of West Coast Bancorp (“West Coast”) which was completed on April 1, 2013, Columbia recognized $72 thousand in acquisition-related expenses for the nine month period ended September 30, 2015, and $2.8 million and $4.4 million in acquisition-related expenses for the three and nine month periods ended September 30, 2014, respectively.

Loans

The Company’s loan portfolio includes originated and purchased loans. Originated loans and purchased loans for which there was no evidence of credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments are referred to collectively as loans, excluding purchased credit impaired loans. Purchased loans for which there was, at acquisition date, evidence of credit deterioration since their origination and it was probable that we would be unable to collect all contractually required payments are referred to as purchased credit impaired loans, or “PCI loans.”

The Company’s loans classified as TDR are loans that have been modified or the borrower has been granted special concessions due to financial difficulties that, if not for the challenges of the borrower, the Company would not otherwise consider. The TDR modifications or concessions are made to increase the likelihood that these borrowers with financial difficulties will be able to satisfy their debt obligations as amended. The concessions granted in the restructurings completed in the three and nine month periods ending September 30, 2015 and 2014 largely consisted of maturity extensions, interest rate modifications or a combination of both. In limited circumstances, a reduction in the principal balance of the loan could also be made as a concession. Credit losses for loans classified as TDR are measured on the same basis as impaired loans. For impaired loans, an allowance is established when the collateral value less selling costs (or discounted cash flows or observable market price) of the impaired loan is lower than the recorded investment of that loan.

The Company had no commitments to lend additional funds on loans classified as TDR as of September 30, 2015 and December 31, 2014. The Company did not have any loans modified as TDR that defaulted within twelve months of being modified as TDR during the three and nine month periods ended September 30, 2015 and 2014.

Purchased Credit Impaired Loans (“PCI Loans”)

PCI loans are accounted for under ASC 310-30 and initially measured at fair value based on expected future cash flows over the life of the loans. Loans that have common risk characteristics are aggregated into pools. The Company remeasures contractual and expected cash flows, at the pool-level, on a quarterly basis.

Contractual cash flows are calculated based upon the loan pool terms after applying a prepayment factor. Calculation of the applied prepayment factor for contractual cash flows is the same as described below for expected cash flows.

Inputs to the determination of expected cash flows include cumulative default and prepayment data as well as loss severity and recovery lag information. Cumulative default and prepayment data are calculated via a transition matrix. The transition matrix is a matrix of probability values that specifies the probability of a loan pool transitioning into a particular delinquency state (e.g. 0-30 days past due, 31 to 60 days, etc.) given its delinquency state at the remeasurement date. Loss severity factors are based upon either actual charge-off data within the loan pools or industry averages and recovery lags are based upon the collateral within the loan pools.

The excess of cash flows expected to be collected over the initial fair value of purchased credit impaired loans is referred to as the accretable yield and is accreted into interest income over the estimated life of the acquired loans using the effective yield method. Other adjustments to the accretable yield include changes in the estimated remaining life of the acquired loans, changes in expected cash flows and changes of indices for acquired loans with variable interest rates.

Allowance For Loan And Lease Losses And Unfunded Loan Commitments And Letters Of Credit

Allowance For Loan And Lease Losses And Unfunded Loan Commitments And Letters Of Credit Text Block

Allowance for Loan and Lease Losses and Unfunded Commitments and Letters of Credit

Loans, excluding PCI loans

We maintain an allowance for loan and lease losses (“ALLL”) to absorb losses inherent in the loan portfolio. The size of the ALLL is determined through quarterly assessments of the probable estimated losses in the loan portfolio. Our methodology for making such assessments and determining the adequacy of the ALLL includes the following key elements:

1. General valuation allowance consistent with the Contingencies topic of the FASB ASC.

2. Classified loss reserves on specific relationships. Specific allowances for identified problem loans are determined in accordance with the Receivables topic of the FASB ASC.

3. The unallocated allowance provides for other factors inherent in our loan portfolio that may not have been contemplated in the general and specific components of the allowance. This unallocated amount generally comprises less than 5% of the allowance. The unallocated amount is reviewed quarterly based on trends in credit losses, the results of credit reviews and overall economic trends.

The general valuation allowance is calculated quarterly using quantitative and qualitative information about specific loan classes. The minimum required level with respect to which an entity develops a methodology to determine its ALLL is by general categories of loans, such as commercial business, real estate, and consumer. However, the Company’s methodology in determining its ALLL is prepared in a more detailed manner at the loan class level, utilizing specific categories such as commercial business secured, commercial business unsecured, real estate commercial land, and real estate income property multifamily. The quantitative information uses historical losses from a specific loan class and incorporates the loan’s risk rating migration from origination to the point of loss based upon the consideration of an appropriate look back period.

A loan’s risk rating is primarily determined based upon the borrower’s ability to fulfill its debt obligation from a cash flow perspective. In the event there is financial deterioration of the borrower, the borrower’s other sources of income or repayment are also considered, including recent appraisal values for collateral dependent loans. The qualitative information takes into account general economic and business conditions affecting our marketplace, seasoning of the loan portfolio, duration of the business cycle, etc. to ensure our methodologies reflect the current economic environment and other factors as using historical loss information exclusively may not give an accurate estimate of inherent losses within the Company’s loan portfolio.

When a loan is deemed to be impaired, the Company has to determine if a specific valuation allowance is required for that loan. The specific valuation allowance is a reserve, calculated at the individual loan level, for each loan determined to be both impaired and containing a value less than its recorded investment. The Company measures the impairment based on the discounted expected future cash flows, observable market price, or the fair value of the collateral less selling costs if the loan is collateral dependent or if foreclosure is probable. The specific reserve for each loan is equal to the difference between the recorded investment in the loan and its determined impairment value.

The ALLL is increased by provisions for loan and lease losses (“provision”) charged to expense, and is reduced by loans charged off, net of recoveries or a recovery of previous provisions. While the Company’s management believes the best information available is used to determine the ALLL, changes in market conditions could result in adjustments to the ALLL, affecting net income, if circumstances differ from the assumptions used in determining the ALLL.

We have used the same methodology for ALLL calculations during the nine months ended September 30, 2015 and 2014. Adjustments to the percentages of the ALLL allocated to loan categories are made based on trends with respect to delinquencies and problem loans within each class of loans. The Company reviews the ALLL quantitative and qualitative methodology on a quarterly basis and makes adjustments when appropriate. The Company continues to strive towards maintaining a conservative approach to credit quality and will continue to make revisions to our ALLL as necessary to maintain adequate reserves. The Company carefully monitors the loan portfolio and continues to emphasize the importance of credit quality.

Once it is determined that all or a portion of a loan balance is uncollectable, and the amount can be reasonably estimated, the uncollectable portion of the loan is charged-off.

PCI Loans

Purchased credit impaired loans that have common risk characteristics are aggregated into loan pools. When required, we record impairment, at the pool-level, to adjust the pool’s carrying value to its net present value of expected future cash flows. Quarterly, we re-measure expected loan pool cash flows. If, due to credit deterioration, the present value of expected cash flows is less than carrying value, we reduce the loan pool’s carrying value by adjusting the ALLL with an impairment charge to earnings which is recorded as provision for loan losses. If credit quality improves and the present value of expected cash flows exceeds carrying value, we increase the loan pool’s carrying value by recapturing previously recorded ALLL, if any. See Note 5, Loans, for further discussion of the accounting for PCI loans.

Credit losses attributable to draws on purchased credit impaired loans, advanced subsequent to the loan purchase date, are accounted for under ASC 450-20 and those amounts are also subject to the Company’s internal and external credit review. An ALLL is estimated in a similar manner as loans, excluding PCI loans, and a provision for loan losses is charged to earnings as necessary.

Risk Elements

The extension of credit in the form of loans or other credit products to individuals and businesses is one of our principal business activities. Our policies and applicable laws and regulations require risk analysis as well as ongoing portfolio and credit management. We manage our credit risk through lending limit constraints, credit review, approval policies and extensive, ongoing internal monitoring. We also manage credit risk through diversification of the loan portfolio by type of loan, type of industry and type of borrower and by limiting the aggregation of debt to a single borrower.

Risk ratings are reviewed and updated whenever appropriate, with more periodic reviews as the risk and dollar value of loss on the loan increases. In the event full collection of principal and interest is not reasonably assured, the loan is appropriately downgraded and, if warranted, placed on nonaccrual status even though the loan may be current as to principal and interest payments. Additionally, we assess whether an impairment of a loan warrants specific reserves or a write-down of the loan.

Pass loans are generally considered to have sufficient sources of repayment in order to repay the loan in full in accordance with all terms and conditions. Special mention loans have potential weaknesses that, if left uncorrected, may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Loans with a risk rating of Substandard or worse are reported as classified loans in our ALLL analysis. We review these loans to assess the ability of our borrowers to service all interest and principal obligations and, as a result, the risk rating may be adjusted accordingly. Substandard loans reflect loans where a loss is possible if loan weaknesses are not corrected. Doubtful loans have a high probability of loss, however, the amount of loss has not yet been determined. Loss loans are considered uncollectable and when identified, are charged off.

The following is an analysis of the credit quality of our loan portfolio, excluding PCI loans, as of September 30, 2015 and December 31, 2014:

Covered Assets And FDIC Loss Sharing Asset

Covered Assets and FDIC Loss sharing Asset

FDIC Loss-sharing Asset and Covered Assets

We are a party to eight loss-sharing agreements with the FDIC relating to four FDIC-assisted acquisitions. Such agreements cover a substantial portion of losses incurred on acquired covered loans and OREO. The loss-sharing agreements relate to the acquisitions of (1) Columbia River Bank in January 2010, (2) American Marine Bank in January 2010, (3) Summit Bank in May 2011, and (4) First Heritage Bank in May 2011. Under the terms of the loss-sharing agreements, the FDIC will absorb 80% of losses and share in 80% of loss recoveries up to specified amounts. With respect to loss-sharing agreements for two acquisitions completed in 2010, after those specified amounts, the FDIC will absorb 95% of losses and share in 95% of loss recoveries. The loss-sharing provisions of the agreements for non-single family and single family mortgage loans are in effect for five and ten years, respectively and the loss recovery provisions are in effect for eight and ten years, respectively. The loss-sharing provisions for the Columbia River Bank and American Marine Bank non-single family covered assets were effective through March 31, 2015. Accordingly, further activity will be limited to recoveries through the first quarter of 2018 for assets covered by these loss-sharing agreements.

Ten years and forty-five days after the applicable acquisition dates, the Bank must pay to the FDIC a clawback in the event the losses from the acquisitions fail to reach stated levels. The amount of the clawback is determined by a formula specified in each individual loss-sharing agreement. As of September 30, 2015, the net present value of the Bank’s estimated clawback liability was $4.3 million, which was included in other liabilities on the consolidated balance sheets.

At September 30, 2015, the FDIC loss-sharing asset was comprised of a $6.7 million FDIC indemnification asset and a $1.4 million FDIC receivable. The indemnification asset represents the net present value of cash flows the Company expects to collect from the FDIC under the loss-sharing agreements and the FDIC receivable represents amounts from the FDIC for which the Company has requested reimbursement but has not yet received reimbursement.

For PCI loans, the Company remeasures contractual and expected cash flows on a quarterly basis. When the quarterly remeasurement process results in a decrease in expected cash flows due to an increase in expected credit losses, impairment is recorded. As a result of this impairment, for loans covered by loss-sharing agreements with respect to which the loss-sharing provisions are still effective, the indemnification asset is increased to reflect anticipated future cash to be received from the FDIC. Consistent with the loss-sharing agreements between the Company and the FDIC, the amount of the increase to the indemnification asset is measured as 80% of the resulting impairment.

Alternatively, when the quarterly remeasurement results in an increase in expected future cash flows due to a decrease in expected credit losses, the nonaccretable difference decreases and the effective yield of the related loan portfolio is increased. As a result of the improved expected cash flows, for loans covered by loss-sharing agreements with respect to which the loss-sharing provisions are still effective, the indemnification asset would be reduced first by the amount of any impairment previously recorded and, second, by increased amortization over the remaining life of the related loss-sharing agreement.

The following table shows a detailed analysis of the FDIC loss-sharing asset for the three and nine months ended September 30, 2015 and 2014:

Fair Value Disclosures [Abstract]

Fair Value Accounting and Measurement

Fair Value Accounting and Measurement

The Fair Value Measurements and Disclosures topic of the FASB ASC defines fair value, establishes a consistent framework for measuring fair value and expands disclosure requirements about fair value. We hold fixed and variable rate interest-bearing securities, investments in marketable equity securities and certain other financial instruments, which are carried at fair value. Fair value is determined based upon quoted prices when available or through the use of alternative approaches, such as matrix or model pricing, when market quotes are not readily accessible or available.

The valuation techniques are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our own market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1 – Quoted prices for identical instruments in active markets that are accessible at the measurement date.

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable.

Fair values are determined as follows:

Securities at fair value are priced using a combination of market activity, industry recognized information sources, yield curves, discounted cash flow models and other factors. These fair value calculations are considered a Level 2 input method under the provisions of the Fair Value Measurements and Disclosures topic of the FASB ASC for all securities other than U.S. Treasury notes, which are considered a Level 1 input method.

Interest rate contract positions are valued in models, which use as their basis, readily observable market parameters and are classified within Level 2 of the valuation hierarchy.

The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis at September 30, 2015 and December 31, 2014 by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement:

Nonrecurring Measurements

Certain assets and liabilities are measured at fair value on a nonrecurring basis after initial recognition such as loans measured for impairment and OREO. The following methods were used to estimate the fair value of each such class of financial instrument:

Impaired loans—A loan is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, a loan’s observable market price, or the fair market value of the collateral less estimated costs to sell if the loan is a collateral-dependent loan. Generally, the Company utilizes the fair market value of the collateral to measure impairment. The impairment evaluations are performed in conjunction with the ALLL process on a quarterly basis by officers in the Special Credits group, which reports to the Chief Credit Officer. The Real Estate Appraisal Services Department (“REASD”), which also reports to the Chief Credit Officer, is responsible for obtaining appraisals from third-parties or performing internal evaluations. If an appraisal is obtained from a third-party, the REASD reviews the appraisal to evaluate the adequacy of the appraisal report, including its scope, methods, accuracy, and reasonableness.

Other real estate owned—OREO is real property that the Bank has taken ownership of in partial or full satisfaction of a loan or loans. OREO is generally measured based on the property’s fair market value as indicated by an appraisal or a letter of intent to purchase. OREO is initially recorded at the fair value less estimated costs to sell. This amount becomes the property’s new basis. Any fair value adjustments based on the property’s fair value less estimated costs to sell at the date of acquisition are charged to the ALLL, or in the event of a write-up without previous losses charged to the ALLL, a credit to earnings is recorded. Management periodically reviews OREO in an effort to ensure the property is recorded at its fair value, net of estimated costs to sell. Any fair value adjustments subsequent to acquisition are charged or credited to earnings. The initial and subsequent evaluations are performed by officers in the Special Credits group, which reports to the Chief Credit Officer. The REASD obtains appraisals from third-parties for OREO and performs internal evaluations. If an appraisal is obtained from a third-party, the REASD reviews the appraisal to evaluate the adequacy of the appraisal report, including its scope, methods, accuracy, and reasonableness.

The following tables set forth information related to the Company’s assets that were measured using fair value estimates on a nonrecurring basis during the current and prior year quarterly periods:

The losses on impaired loans disclosed above represent the amount of the specific reserve and/or charge-offs during the period applicable to loans held at period end. The amount of the specific reserve is included in the allowance for loan and lease losses. The losses on OREO disclosed above represent the write-downs taken at foreclosure that were charged to the allowance for loan and lease losses, as well as subsequent changes in any valuation allowances from updated appraisals that were recorded to earnings.

Quantitative information about Level 3 fair value measurements

The range and weighted-average of the significant unobservable inputs used to fair value our Level 3 nonrecurring assets, along with the valuation techniques used, are shown in the following table:

	Fair value at September 30, 2015		Valuation Technique	Unobservable Input	Range (Weighted Average) (1)
	(dollars in thousands)
Impaired loans	$	350	Fair Market Value of Collateral	Adjustment to Appraisal Value	N/A (2)
OREO	3,286		Fair Market Value of Collateral	Adjustment to Appraisal Value	N/A (2)
(1) Discount applied to appraisal value, letter of intent to purchase, or stated value (in the case of accounts receivable, inventory and equipment).
(2) Quantitative disclosures are not provided for impaired loans and OREO because there were no adjustments made to the appraisal value during the current period.

(3) Other collateral consists of accounts receivable, inventory and equipment.

Fair value of financial instruments

Because broadly traded markets do not exist for most of the Company’s financial instruments, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein do not represent, and should not be construed to represent, the underlying value of the Company.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Cash and due from banks and interest-earning deposits with banks—The fair value of financial instruments that are short-term or reprice frequently and that have little or no risk are considered to have a fair value that approximates carrying value (Level 1).

Securities available for sale—Securities at fair value, other than U.S. Treasury Notes, are priced using a combination of market activity, industry recognized information sources, yield curves, discounted cash flow models and other factors (Level 2). U.S. Treasury Notes are priced using quotes in active markets (Level 1).

Federal Home Loan Bank stock—The fair value is based upon the par value of the stock which equates to its carrying value (Level 2).

Loans held for sale—The carrying amount of loans held for sale approximates their fair values due to the short period of time between the origination and sale dates (Level 2).

Loans—Loans are not recorded at fair value on a recurring basis. Nonrecurring fair value adjustments are periodically recorded on impaired loans that are measured for impairment based on the fair value of collateral. For most performing loans, fair value is estimated using expected duration and lending rates that would have been offered on September 30, 2015 or December 31, 2014, for loans which mirror the attributes of the loans with similar rate structures and average maturities. The fair values resulting from these calculations are reduced by an amount representing the change in estimated fair value attributable to changes in borrowers’ credit quality since the loans were originated. For nonperforming loans, fair value is estimated by applying a valuation discount based upon loan sales data from the FDIC. For PCI loans, fair value is estimated by discounting the expected future cash flows using a lending rate that would have been offered on September 30, 2015 (Level 3).

FDIC loss-sharing asset —The fair value of the FDIC loss-sharing asset is estimated based on discounting the expected future cash flows using an estimated market rate (Level 3).

Interest rate contracts—Interest rate swap positions are valued in models, which use readily observable market parameters as their basis (Level 2).

Deposits—For deposits with no contractual maturity, the fair value is equal to the carrying value (Level 1). The fair value of fixed maturity deposits is based on discounted cash flows using the difference between the deposit rate and current market rates for deposits of similar remaining maturities (Level 2).

FHLB advances—The fair value of FHLB advances is estimated based on discounting the future cash flows using the market rate currently offered (Level 2).

Repurchase Agreements—The fair value of term repurchase agreements is estimated based on discounting the future cash flows using the market rate currently offered. The carrying amount of sweep repurchase agreements approximates their fair values due to the short period of time between repricing dates (Level 2).

Other Borrowings— Other borrowings are trust preferred obligations assumed by the Company in the Intermountain acquisition. The fair value is estimated as the carrying value as these obligations are redeemable and a market participant would expect redemption in the near-term (Level 2).

Other Financial Instruments—The majority of our commitments to extend credit and standby letters of credit carry current market interest rates if converted to loans, as such, carrying value is assumed to equal fair value.

The following tables summarize carrying amounts and estimated fair values of selected financial instruments as well as assumptions used by the Company in estimating fair value at September 30, 2015 and December 31, 2014:

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Accounting Pronouncements Recently Issued

Accounting Pronouncements Recently Issued

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the codification. For public companies, this update was to be effective for interim and annual periods beginning after December 15, 2016. However, in August 2015, the FASB issued ASU 2015-14, which delayed the effective date of ASU 2014-09 by one year and permits companies to voluntarily adopt the new standard as of the original effective date. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements, but does not expect the guidance to have a material impact on the Company’s consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments. the amendments in ASU 2015-16 require that the acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amount is determined. The acquirer is required to also record, in the same period’s financial statements, the effect on earnings as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. In addition, an entity is required to present separately on the face of the income statement or disclose in the notes to the financial statements the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The amendments in ASU 2015-16 are effective for years beginning after December 15, 2015. Early adoption is permitted for reporting periods for which financial statements have not been issued. The Company adopted the amendments in ASU 2015-16 during the current quarter.
