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 six months ended June 30, 2014 are not necessarily indicative of results to be anticipated for the year ending December 31, 2014. The accompanying interim unaudited consolidated financial statements should be read in conjunction with the financial statements and related notes contained in the Company’s 2013 Annual Report on Form 10-K.

Due to the timing of the acquisition of West Coast Bancorp (“West Coast”), our results of operations for the six month period ended June 30, 2014 include the acquisition for the full six month period, however the prior year period only includes the acquisition for three months of the six month period. 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 2013 Annual Report on Form 10-K. There have not been any changes in our significant accounting policies compared to those contained in our 2013 Form 10-K disclosure for the year ended December 31, 2013.

Accounting Pronouncements Recently Issued

In June 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Services Period. The amendments in ASU 2014-12 provide guidance for determining compensation cost under specific circumstances when an employee is eligible to vest in an award regardless of whether the employee is rendering service on the date the performance target is achieved. ASU 2014-12 becomes effective for annual and interim periods beginning after December 15, 2015 with early adoption permitted. As of June 30, 2014, the Company did not have any share-based payment awards that include performance targets that could be achieved after the requisite service period. As such, the adoption of ASU No. 2014-12 is not expected to have a material impact on the Company’s consolidated financial statements.

In June 2014, the FASB issued ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The amendments in ASU 2014-11 change the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with accounting for other repurchase agreements. Additionally, the amendment requires new disclosures on transfers accounted for as sales in transactions that are economically similar to repurchase agreements and requires increased transparency on collateral pledged in secured borrowings. The amendments in this update will be effective for the first interim or annual period beginning after December 31, 2014, with the exception of the collateral disclosures which will be effective for interim periods beginning after March 15, 2015. Early application is not permitted. 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 May 2014, the FASB issued ASU 2014-04 No. 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 will be effective for interim and annual periods beginning after December 15, 2016. 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 April 2014, the the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. The Company is assessing the impact of the new guidance on its consolidated financial statements.

In January 2014, the FASB issued ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure. The Update clarifies when a creditor would be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that all or a portion of the loan would be derecognized and the real estate property recognized. Under the guidance, a consumer loan collateralized by residential real estate should be reclassified to other real estate owned when (1) the creditor obtains legal title to the residential property or (2) the borrower conveys all interest in the property to the creditor to satisfy the loan by completing a deed in lieu of foreclosure or similar agreement. In addition, an entity is required to disclose the amount of residential real estate meeting the conditions above, and the recorded investment in consumer mortgage loans secured by residential real estate that are in the process of foreclosure. ASU 2014-04 is effective for annual and interim reporting periods within those annual periods, beginning after December 15, 2014. Adoption of the new guidance is not expected to have a significant impact on the Company’s consolidated financial statements.

In January 2014, the FASB issued ASU No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. The Update provides guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit. The amendments in this Update permit the reporting entity to make an accounting policy election to account for its investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, the cost of the investment is amortized each reporting period in proportion to the tax credits received. Under the new guidance, classification of the amortization would change from noninterest expense to income tax expense. ASU 2014-01 is effective for annual and interim reporting periods within those annual periods, beginning after December 15, 2014. The guidance is to be applied retrospectively to all periods presented. The Company is assessing the impact of the new guidance on its consolidated financial statements.

Business Combinations

On April 1, 2013, the Company completed its acquisition of West Coast. The Company paid $540.8 million in total consideration to acquire 100% of the voting equity interests of West Coast. The primary reason for the acquisition was to expand the Company’s geographic footprint consistent with its ongoing growth strategy. The fair value of the net assets acquired totaled $312.4 million, including $1.88 billion of deposits, $1.41 billion of loans and $15.3 million of other intangible assets. Goodwill of $228.4 million was recorded as part of the acquisition. The goodwill is not deductible for income tax purposes.

The operating results of the Company include the operating results produced by the acquired assets and assumed liabilities for the period April 1, 2013 to June 30, 2014. Disclosure of the amount of West Coast’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.

The following table presents certain unaudited pro forma information for the six month period ended June 30, 2013, for illustrative purposes only. This unaudited pro forma information was calculated as if West Coast had been acquired as of the beginning of the year prior to the acquisition. The unaudited estimated pro forma information combines the historical results of West Coast with the Company’s consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods. 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 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 West Coast acquisition, Columbia recognized $672 thousand and $9.2 million of acquisition-related expenses for the three month periods ended June 30, 2014 and 2013, respectively, and $1.6 million and $10.0 million for the six month periods ended June 30, 2014 and 2013, respectively.

See Note 2, Business Combinations, in Item 8 of our 2013 Form 10-K for additional details related to the West Coast acquisition.

At June 30, 2014, there were 54 U.S. government agency and government-sponsored enterprise mortgage-backed securities and collateralized mortgage obligations securities in an unrealized loss position, of which 45 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 June 30, 2014.

At June 30, 2014, there were 88 state and municipal government securities in an unrealized loss position, of which 64 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 June 30, 2014, 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 June 30, 2014.

At June 30, 2014, there were 27 U.S. government agency and government-sponsored enterprise securities in an unrealized loss position, 22 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 June 30, 2014.

At June 30, 2014, there were two U.S. government securities in an unrealized loss position, both 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 June 30, 2014.

At June 30, 2014, there were two other securities in an unrealized loss position, both of which were 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 these investments to be other-than-temporarily impaired at June 30, 2014 as it has the intent and ability to hold the investments for sufficient time to allow for recovery in the market value.

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 six month periods ending June 30, 2014 and 2013 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 commitments to lend $269 thousand of additional funds on loans classified as TDR as of June 30, 2014, but had no commitments to lend additional funds on loans classified as TDR as of December 31, 2013. The Company did not have any loans modified as TDR that defaulted within twelve months of being modified as TDR during the six month periods ended June 30, 2014 and 2013.

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

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


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

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 Accounting Standards Codification (“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 systematically 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 allowance for loan and lease losses is by general categories of loans, such as commercial business, real estate, and consumer. However, the Company’s methodology in determining its allowance for loan and lease losses 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 six months ended June 30, 2014 and 2013. 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 prudently adjust our ALLL as necessary in order 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.

The following tables show a detailed analysis of the allowance for loan and lease losses for noncovered loans for the three and six months ended June 30, 2014 and 2013:

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, 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 allowance for loan and lease losses 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 noncovered loan portfolio as of June 30, 2014 and December 31, 2013:

Covered Assets and FDIC Loss-sharing Asset

Covered Assets and FDIC Loss sharing Asset

Covered Assets and FDIC Loss-sharing Asset

Covered Assets

Covered assets consist of loans and OREO acquired in certain FDIC-assisted acquisitions during 2010 and 2011, for which the Bank entered into loss-sharing agreements, whereby the FDIC will cover a substantial portion of future losses on loans (and related unfunded loan commitments), OREO and certain accrued interest on loans during the terms of the agreements. 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 commercial and single-family mortgage loans are in effect for five and ten years, respectively, from the acquisition dates and the loss recovery provisions are in effect for eight and ten years, respectively, from the acquisition dates.

Ten years and forty-five days after the 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 June 30, 2014, the net present value of the Bank’s estimated clawback liability is $4.0 million, which is included in other liabilities on the consolidated balance sheets.

The following is an analysis of our covered loans, net of related allowance for losses as of June 30, 2014 and December 31, 2013:

Acquired impaired 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. Acquired 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.

Acquired impaired loans are also subject to the Company’s internal and external credit review and are risk rated using the same criteria as loans originated by the Company. However, risk ratings are not a clear indicator of losses on acquired loans as the loans were acquired with a significant discount and a majority of the losses are recoverable from the FDIC under the loss-sharing agreements.

Losses attributable to draws on acquired loans, advanced subsequent to the loan acquisition date, are accounted for under ASC 450-20 and those amounts are also subject to the Company’s internal and external credit review. An allowance for loan losses is estimated in a similar manner as the originated loan portfolio, and a provision for loan losses is charged to earnings as necessary.

The excess of cash flows expected to be collected over the initial fair value of acquired 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.

The following table shows the changes in accretable yield for acquired loans for the three and six months ended June 30, 2014 and 2013:

During the three months ended June 30, 2014, the Company recorded a provision for losses on covered loans of $1.5 million. Of this amount, $1.7 million was impairment calculated in accordance with ASC 310-30 and $200 thousand was a provision recapture to adjust the allowance for loss calculated under ASC 450-20 for draws on acquired loans. The impact to earnings of the $1.5 million of provision for covered loans was partially offset through noninterest income by a $1.2 million favorable adjustment to the change FDIC loss-sharing asset line item.

The changes in the ALLL for covered loans for the three and six months ended June 30, 2014 and 2013 are summarized as follows:

Total covered OREO at end of period	$	13,051		$	12,854		$	13,051		$	12,854

The covered OREO is subject to loss-sharing agreements with the FDIC in which the FDIC will share in 80% of additional write-downs, as well as gains and losses on covered OREO sales, or 95%, if applicable, of additional write-downs, as wells as gains and losses on covered OREO sales if the minimum loss share thresholds are met.

FDIC Loss-sharing Asset

At June 30, 2014, the FDIC loss-sharing asset is comprised of a $25.0 million FDIC indemnification asset and a $2.9 million FDIC receivable. The indemnification represents the cash flows the Company expects to collect from the FDIC under the loss-sharing agreements and the FDIC receivable represents the reimbursable amounts from the FDIC that have not yet been received.

For covered 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, 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, 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 six months ended June 30, 2014 and 2013:

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 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:

(1) Goodwill established through acquisitions has been retrospectively adjusted for the prior year periods due to adjustments to provisional amounts made related to the West Coast acquisition. See Note 3, Business Combinations, for additional information regarding goodwill and intangible assets recorded related to the acquisition of West Coast on April 1, 2013.

The following table provides the estimated future amortization expense of core deposit intangibles for the remaining six months ending December 31, 2014 and the succeeding four years:

Shareholders' Equity

Shareholders’ Equity

Preferred Stock. In conjunction with the 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.

Warrants to Purchase Common Stock. In conjunction with the acquisition of West Coast, the Company issued Amended and Restated Warrants (the “Warrants”) to purchase shares of Company common stock at an exercise price of $8.58 per share. The Company’s Amended and Restated Warrants amended and restated Class C Warrants previously issued by West Coast. The Warrants were immediately exercisable and will expire on October 23, 2016. At June 30, 2014, the aggregate number of shares of Company common stock and value called for by warrants outstanding was 582,799 and $5.0 million, respectively. This reflects the exercise of 1,631,840 warrant shares during the six month period ended June 30, 2014. As the warrants contain a cashless exercise feature, the net shares issued by the Company as a result of this exercise activity was 1,139,698.

Dividends. On January 23, 2014 the Company declared a quarterly cash dividend of $0.12 per common share and common share equivalent for holders of preferred stock, payable on February 19, 2014 to shareholders of record at the close of business February 5, 2014. On April 23, 2014, the Company declared a regular quarterly cash dividend of $0.12 per common share, and common share equivalent for holders of preferred stock, and a special, one-time cash dividend of $0.12 per common share, and common share equivalent for holders of preferred stock, both payable on May 21, 2014 to shareholders of record at the close of business May 7, 2014. Subsequent to quarter end, on July 23, 2014, the Company declared a regular quarterly cash dividend of $0.14 per common share, and common share equivalent for holders of preferred stock and a special, one-time cash dividend of $0.14 per common share, and common share equivalent for holders of preferred stock, both payable on August 20, 2014 to shareholders of record at the close of business August 6, 2014. 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.

Derivatives and Balance Sheet Offsetting

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 June 30, 2014 and December 31, 2013 was $208.3 million and $179.5 million, respectively. There was no impact to the statement of income for the three month periods ending June 30, 2014 and 2013.

The following table presents the fair value of derivatives not designated as hedging instruments at June 30, 2014 and December 31, 2013:

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 June 30, 2014 and December 31, 2013 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:

There were no transfers between Level 1 and Level 2 of the valuation hierarchy during the six month periods ended June 30, 2014 and 2013. The Company recognizes transfers between levels of the valuation hierarchy based on the valuation level at the end of the reporting period.

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 and other personal property owned (“OPPO”)—OREO and OPPO are real and personal property that the Bank has taken ownership of in partial or full satisfaction of a loan or loans. OREO and OPPO are generally measured based on the item’s fair market value as indicated by an appraisal or a letter of intent to purchase. OREO and OPPO are recorded at the lower of carrying amount or fair value less estimated costs to sell. This amount becomes the property’s new basis. Any write-downs based on the property fair value less estimated costs to sell at the date of acquisition are charged to the allowance for loan and lease losses. Management periodically reviews OREO and OPPO in an effort to ensure the property is carried at the lower of its new basis or fair value, net of estimated costs to sell. Any write-downs subsequent to acquisition are charged to earnings. The initial and subsequent write-down 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 OPPO 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.

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 June 30, 2014		Valuation Technique	Unobservable Input	Range (Weighted Average) (1)
	(dollars in thousands)
Noncovered OREO	$	1,389	Fair Market Value of Collateral	Adjustment to Appraisal Value	N/A⁽²⁾
Covered OREO	1,837		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 noncovered OREO and covered OREO because there were no adjustments made to the appraisal value during the current period.



	Fair value at June 30, 2013		Valuation Technique	Unobservable Input	Range (Weighted Average) (1)

Noncovered OREO	1,965		Fair Market Value of Collateral	Adjustment to Appraisal Value	N/A⁽²⁾
Covered OREO	395		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 collateralized by real estate, noncovered OREO and covered OREO because there were no adjustments made to the appraisal value during the current period.
(3) Other collateral consists of accounts receivable and inventory.
(4) As there was only one impaired loan collateralized by other collateral, a range of discounts could not be provided.

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—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 June 30, 2014 or December 31, 2013, 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 covered loans, fair value is estimated by discounting the expected future cash flows using a lending rate that would have been offered on June 30, 2014 (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 Federal Home Loan Bank of Seattle (the “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 securities sold under agreement to repurchase is estimated based on discounting the future cash flows using the market rate currently offered (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 June 30, 2014 and December 31, 2013:

Earnings per Common Share

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 six months ended June 30, 2014 and 2013:



	Three Months Ended				Six Months Ended

Diluted earnings per common share	$	0.40	$	0.28	$	0.77	$	0.58
Potentially dilutive share options that were not included in the computation of diluted EPS because to do so would be anti-dilutive	63		143		73		76

__________


(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.

Subsequent Event

Subsequent Events [Text Block]

Subsequent Event

On July 23, 2014, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Intermountain Community Bancorp, an Idaho corporation (“Intermountain”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, Intermountain will merge with and into Columbia (the “Merger”), with Columbia continuing as the surviving corporation. Immediately after the Merger, Panhandle State Bank, an Idaho state-chartered bank and wholly-owned subsidiary of Intermountain, will merge with and into our wholly-owned subsidiary, Columbia Bank. The closing of the transaction is subject to the satisfaction of certain customary conditions, including, among other things, the receipt of required regulatory approvals and the approval of Intermountain’s shareholders. Under the terms of the merger agreement, Intermountain shareholders are entitled to receive in respect of each share of Intermountain common stock, consideration in the form of cash, Columbia common stock or a unit consisting of a mix of 0.6426 of a share of Columbia common stock and $2.2930 in cash. Based on Columbia’s closing stock price as of July 23, 2014, the merger consideration was valued at $121.5 million, or approximately $18.22 per Intermountain share. The value of the merger consideration will fluctuate based on the value of Columbia’s stock until closing.

Business Acquisition, Pro Forma Information [Table Text Block]

The following table presents certain unaudited pro forma information for the six month period ended June 30, 2013, for illustrative purposes only. This unaudited pro forma information was calculated as if West Coast had been acquired as of the beginning of the year prior to the acquisition. The unaudited estimated pro forma information combines the historical results of West Coast with the Company’s consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods. 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 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.

Fair Value Inputs, Assets, Quantitative Information

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:

	(dollars in thousands)
Noncovered OREO	$	1,389	Fair Market Value of Collateral	Adjustment to Appraisal Value	N/A⁽²⁾
Covered OREO	1,837		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 noncovered OREO and covered OREO because there were no adjustments made to the appraisal value during the current period.



	Fair value at June 30, 2013		Valuation Technique	Unobservable Input	Range (Weighted Average) (1)

Noncovered OREO	1,965		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 collateralized by real estate, noncovered OREO and covered OREO because there were no adjustments made to the appraisal value during the current period.
(3) Other collateral consists of accounts receivable and inventory.
(4) As there was only one impaired loan collateralized by other collateral, a range of discounts could not be provided.

__________


(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.
