The Company’s accounting and reporting policies conform to accounting principles generally accepted in the United States of America (“GAAP”) and practices in the financial services industry. To prepare the financial statements in conformity with GAAP, management must make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, and income and expenses during the reporting period. Circumstances and events that differ significantly from those underlying our estimates and assumptions could cause actual financial results to differ from our estimates. The most significant estimates included in the financial statements relate to the allowance for loan and lease losses, business combinations, purchased credit impaired loans, Federal Deposit Insurance Corporation (“FDIC”) loss sharing asset and goodwill impairment.
The Company has applied its accounting policies and estimation methods consistently in all periods presented in these financial statements (to the periods in which they applied), except for the adoption of Accounting Standards Update (“ASU”) 2012-06 Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution on January 1, 2013. As a result of adoption of the ASU, the Company adjusted the indemnification asset amortization period to be the term of the FDIC loss-sharing agreement if it was shorter than the term of the acquired loans.
Correction of Immaterial Error Related to Prior Periods
During the year ended December 31, 2014, the Company made a $2.6 million adjustment which increased interest income on taxable securities as a result of identifying that the premium amortization related to the Company’s mortgage-backed securities, as calculated by a third-party provider, was not being amortized utilizing an acceptable method under accounting principles generally accepted in the United States. The adjustment reflects the one-time correction necessary to change the accounting for premium amortization to be in conformity with the interest method. Based upon an evaluation of all relevant factors, management believes the correcting adjustment did not have a material impact on the Company’s current or previously reported results.
Consolidation
The consolidated financial statements of the Company include the accounts of the Corporation and its subsidiaries, including the Bank and West Coast Trust. Intercompany balances and transactions have been eliminated in consolidation.
Cash and cash equivalents
Cash and cash equivalents include cash and due from banks, and interest bearing balances due from correspondent banks and the Federal Reserve Bank. Cash and cash equivalents have a maturity of 90 days or less at the time of purchase.
Securities
Securities are classified based on management’s intention on the date of purchase. All securities are classified as available for sale and are presented at fair value. Unrealized gains or losses on securities available for sale are excluded from net income but are included as separate components of other comprehensive income, net of taxes. Purchase premiums or discounts on securities available for sale are amortized or accreted into income using the interest method over the terms of the individual securities. The Company performs a quarterly assessment to determine whether a decline in fair value below amortized cost is other-than-temporary. Amortized cost includes adjustments made to the cost of an investment for accretion, amortization, collection of cash and previous other-than temporary impairment recognized in earnings. Other-than-temporary impairment exists when it is probable that the Company will be unable to recover the entire amortized cost basis of the security.
In performing the quarterly assessment for debt securities, management considers whether or not the Company expects to recover the entire amortized cost basis of the security. In addition, management also considers whether it is more likely than not that it will not have to sell the security before recovery of its cost basis. If the Company intends to sell a security or it is more likely than not it will be required to sell a security prior to recovery of its cost basis, the entire amount of impairment is recognized in earnings. If the Company does not intend to sell the security or it is not more likely than not it will be required to sell the security prior to recovery of its cost basis, the credit loss component of impairment is recognized in earnings and impairment associated with non-credit factors, such as market liquidity, is recognized in other comprehensive income net of tax. A credit loss is the difference between the cost basis of the security and the present value of cash flows expected to be collected, discounted at the security’s effective interest rate at the date of acquisition. The cost basis of an other-than-temporarily impaired security is written down by the amount of impairment recognized in earnings. The new cost basis is not adjusted for subsequent recoveries in fair value. However, the difference between the new amortized cost basis and the cash flows expected to be collected is accreted as interest income. The total other-than-temporary impairment, if any, is presented in the consolidated statements of income with a reduction for the amount of other-than-temporary impairment that is recognized in other comprehensive income, if any.
Realized gains or losses on sales of securities available for sale are recorded using the specific identification method.
Federal Home Loan Bank Stock
The Company’s investment in Federal Home Loan Bank (“FHLB”) stock is carried at par value because the shares can only be redeemed with the FHLB at par. The Company is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages and FHLB advances. Stock redemptions are at the discretion of the FHLB or of the Company, upon five years’ prior notice for FHLB Class B stock or six months notice for FHLB Class A stock to the FHLB. FHLB stock is subject to recoverability testing per the Financial Services—Depository and Lending topic of the FASB Accounting Standards Codification (“ASC”).
Loans
Loans, excluding purchased credit impaired loans are generally carried at the unpaid principal balance, net of premiums, unearned discounts and net deferred loan fees. Net deferred loan fees include deferred unamortized fees less direct incremental loan origination costs. Net deferred loan fees, premiums and unearned discounts are amortized into interest income using either the interest method or straight-line method over the terms of the loans, adjusted for actual prepayments. The amortization is calculated using the interest method for all loans except revolving loans, for which the straight-line method is used. Interest income is accrued as earned. Fees related to lending activities other than the origination or purchase of loans are recognized as noninterest income during the period the related services are performed.
Nonaccrual loans—Loans are placed on nonaccrual status when a loan becomes contractually past due 90 days with respect to interest or principal unless the loan is both well secured and in the process of collection, or if full collection of interest or principal becomes uncertain. When a loan is placed on nonaccrual status, any accrued and unpaid interest receivable is reversed and the recognition of net deferred loan fees, premiums and unearned discounts ceases. Thereafter, interest collected on the loan is accounted for on the cash collection or cost recovery method until qualifying for return to accrual status. Generally, a loan may be returned to accrual status when the delinquent principal and interest are brought current in accordance with the terms of the loan agreement for a minimum period of six months and future payments are reasonably assured.
Impaired loans—Loans are considered impaired when based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement or when a loan has been modified in a troubled debt restructuring. The assessment for impairment occurs when and while such loans are designated as classified per the Company’s internal risk rating system or when and while such loans are on nonaccrual. All nonaccrual loans greater than $500,000 and all troubled debt restructured loans are considered impaired and analyzed individually on a quarterly basis. Classified loans with an outstanding balance greater than $500,000 are evaluated for potential impairment on a quarterly basis.
When a loan with unique risk characteristics has been identified as being impaired, the amount of impairment will be measured by the Company using discounted cash flows, except when it is determined that the remaining source of repayment for the loan is the operation or liquidation of the underlying collateral. In these cases, the current fair value of the collateral, reduced by costs to sell, will be used in place of discounted cash flows. As a final alternative, the observable market price of the debt may be used to assess impairment. Predominantly, the Company uses the fair value of collateral approach based upon a reliable valuation.
When the measurement of the impaired loan is less than the recorded amount of the loan, an impairment is recognized by recording a charge-off to the allowance for loan and lease losses or by designating a specific reserve. The Company’s policy is to record cash receipts received on impaired loans first as reductions to principal and then to interest income.
Restructured Loans—A loan is classified as a troubled debt restructuring when a borrower is experiencing financial difficulties that lead to a restructuring of the loan, and the Company grants concessions to the borrower in the restructuring that it would not otherwise consider. These concessions may include interest rate reductions, principal forgiveness, extension of maturity date and other actions intended to minimize potential losses. Generally, a nonaccrual loan that is restructured remains on nonaccrual status for a period of six months to demonstrate that the borrower can meet the restructured terms. If the borrower’s performance under the new terms is not reasonably assured, the loan remains classified as a nonaccrual loan.
Purchased Credit Impaired Loans (“PCI Loans”)—Loans acquired with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are accounted for under ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, formerly SOP 03-3 Accounting for Certain Loans or Debt Securities Acquired in a Transfer. In addition, because of the significant discounts associated with certain of the acquired loan portfolios, the Company elected to account for those certain acquired loans under ASC 310-30.
In situations where such loans have similar risk characteristics, loans are aggregated into pools to estimate cash flows. A pool is accounted for as a single asset with a single interest rate, cumulative loss rate and cash flow expectation. Expected cash flows at the acquisition date in excess of the fair value of loans are considered to be accretable yield, which is recognized as interest income over the life of the loan pool using a level yield method if the timing and amount of the future cash flows of the pool is reasonably estimable. Subsequent to the acquisition date, any increases in cash flow over those expected at purchase date in excess of fair value are recorded as interest income prospectively. Any subsequent decreases in cash flow over those expected at purchase date due to credit deterioration are recognized by recording an allowance for losses on purchased credit impaired loans. Any disposals of loans, including sales of loans, payments in full or foreclosures result in the removal of the loan from the loan pool at the carrying amount.
Unfunded loan commitments—Unfunded commitments are generally related to providing credit facilities to clients of the Bank and are not actively traded financial instruments. These unfunded commitments are disclosed as financial instruments with off-balance sheet risk in Note 17 in the Notes to Consolidated Financial Statements.
Allowance for Loan and Lease Losses
The Company accounts for the credit risk associated with lending activities through its allowance for loan and lease losses and provision for loan and lease losses. The provision is the expense recognized in the consolidated statements of income to adjust the allowance to the levels deemed appropriate by management, as determined through application of the Company’s allowance methodology procedures. The provision for loan and lease losses reflects management’s judgment of the adequacy of the allowance for loan and lease losses. Loan and lease losses are charged against the allowance when management believes the collectability of a loan balance is unlikely. Subsequent recoveries, if any, are credited to the allowance.
The allowance for loan and lease losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, and estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.
The allowance consists of general, specific, and unallocated components. The general component covers loans not specifically measured for impairment and is based on historical loss experience adjusted for qualitative factors. The specific component relates to loans that are impaired. For impaired loans an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The unallocated allowance provides for other credit losses inherent in the Company’s 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 periodically based on trends in credit losses, the results of credit reviews and overall economic trends.
Allowance for Loan Losses on Purchased Credit Impaired Loans
The Company updates its cash flow projections for purchased credit impaired loans accounted for under ASC 310-30 on a quarterly basis. Assumptions utilized in this process include projections related to probability of default, loss severity, prepayment and recovery lag. Projections related to probability of default and prepayment are calculated utilizing a loan migration analysis. The loan migration analysis is a matrix of probability that is used to estimate the probability of a loan pool transitioning into a particular delinquency state 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.
Any decreases in expected cash flows after the acquisition date and subsequent measurement periods are recognized by recording a provision for loan losses. See Purchased Credit Impaired Loans for further discussion.
Allowance for Unfunded Commitments and Letters of Credit
The allowance for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to these unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. The allowance for unfunded commitments is included in other liabilities on the consolidated balance sheets, with changes to the balance charged against noninterest expense.
Premises and Equipment
Land, buildings, leasehold improvements and equipment are stated at cost less accumulated depreciation and amortization. Gains or losses on dispositions are reflected in current operations. Expenditures for improvements and major renewals are capitalized, and ordinary maintenance, repairs and small purchases are charged to operating expenses. Depreciation and amortization are computed based on the straight-line method over the estimated useful lives of the various classes of assets. The ranges of useful lives for the principal classes of assets are as follows:
Buildings and building improvements
5 to 39 years
Leasehold improvements
Term of lease or useful life, whichever is shorter
Furniture, fixtures and equipment
3 to 7 years
Vehicles
5 years
Computer software
3 to 5 years

Software
Capitalized software is stated at cost, less accumulated amortization. Amortization is computed on a straight-line basis and charged to expense over the estimated useful life of the software which is generally three years. Capitalized software is included in Premises and equipment, net in the consolidated balance sheets.
Other Real Estate Owned
OREO is composed of real estate acquired in satisfaction of loans. Properties acquired by foreclosure or deed in lieu of foreclosure are transferred to OREO and are recorded at fair value less estimated costs to sell, at the date of transfer of the property. If the carrying value exceeds the fair value at the time of the transfer, the difference is charged to the allowance for loan and lease losses. The fair value of the OREO property is based upon current appraisal. Losses that result from the ongoing periodic valuation of these properties are charged to the net cost of operation of OREO in the period in which they are identified. Improvements to the OREO are capitalized and holding costs are charged to the net cost of operation of OREO as incurred.
FDIC Loss-sharing Asset
The acquisition date fair value of the reimbursement the Company expected to receive from the FDIC under loss-sharing agreements was recorded in the FDIC loss-sharing asset on the consolidated balance sheet. Subsequent to initial recognition, the FDIC loss-sharing 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 assets. Any decrease in expected cash flows for the covered assets due to an increase in expected credit losses will increase the FDIC loss-sharing asset and any increase in expected future cash flows for the covered assets due to a decrease in expected credit losses will decrease the FDIC loss-sharing 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.
Goodwill and Intangibles
Net assets of companies acquired in purchase transactions are recorded at fair value at the date of acquisition. Identified intangibles are amortized on an accelerated basis over the period benefited. Goodwill is not amortized but is reviewed for potential impairment during the third quarter on an annual basis or, more frequently, if events or circumstances indicate a potential impairment, at the reporting unit level. A reporting unit is an operating segment or one level below an operating segment for which discrete financial information is available and regularly reviewed by management. The Company consists of a single reporting unit. If the fair value of the reporting unit, including goodwill, is determined to be less than the carrying amount of the reporting unit, a further test is required to measure the amount of impairment. If an impairment loss exists, the carrying amount of goodwill is adjusted to a new cost basis. Subsequent reversal of a previously recognized goodwill impairment loss is prohibited.
Intangible assets are evaluated for impairment if events and circumstances indicate a possible impairment. Such evaluation of other intangible assets is based on undiscounted cash flow projections. At December 31, 2014, intangible assets included on the consolidated balance sheets principally consists of a core deposit intangible amortized using an accelerated method with an original estimated life 10 years.
Income Taxes
The provision for income taxes includes current and deferred income tax expense on net income adjusted for permanent and temporary differences such as interest income on state and municipal securities and affordable housing credits. Deferred tax assets and liabilities are recognized for the expected future tax consequences of existing temporary differences between the financial reporting and tax reporting basis of assets and liabilities using enacted tax laws and rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. On a quarterly basis, management evaluates deferred tax assets to determine if these tax benefits are expected to be realized in future periods. This determination is based on facts and circumstances, including the Company’s current and future tax outlook. To the extent a deferred tax asset is no longer considered “more likely than not” to be realized, a valuation allowance is established.
We recognize the tax benefit from uncertain tax positions only if it is more likely than not that the tax positions will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize interest and penalties related to unrecognized tax benefits in “Provision for income taxes” in the consolidated statements of income.
Advertising
Advertising costs are generally expensed as incurred.
Earnings per Common Share
The Company’s capital structure includes convertible preferred shares, common shares, restricted common shares, common share options, and during portions of 2014 and 2013, warrants to purchase common shares. Restricted common shares participate in dividends declared on common shares at the same rate as common shares. Preferred shares participate in dividends declared on common shares on an “as if converted” basis. Accordingly, the Company calculates earnings per common share (“EPS”) using the two-class method under the Earnings per Share topic of the FASB ASC. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common shareholders but does not require the presentation of basic and diluted EPS for securities other than common shares.
Under the two-class method, basic EPS is computed by dividing earnings allocated to common shareholders by the weighted average number of common shares outstanding for the period. Earnings allocated to common shareholders represents net income reduced by earnings allocated to participating securities. Participating securities include nonvested restricted stock awards and preferred stock. Diluted EPS is computed in the same manner as basic earnings per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if certain shares issuable upon exercise of options and warrants were included unless those additional shares would have been anti-dilutive. For the diluted EPS computation, the treasury stock method is applied and compared to the two-class method and whichever method results in a more dilutive impact is utilized to calculate diluted EPS.
Share-Based Payment
The Company accounts for stock options and stock awards in accordance with the Compensation—Stock Compensation topic of the FASB ASC. Authoritative guidance requires the Company to measure the cost of employee services received in exchange for an award of equity instruments, such as stock options or stock awards, based on the fair value of the award on the grant date. This cost must be recognized in the consolidated statements of income over the vesting period of the award.
The Company issues restricted stock awards which generally vest over a four- or five-year period during which time the holder receives dividends and has full voting rights. Restricted stock is valued at the closing price of the Company’s stock on the date of an award.
Derivatives and Hedging Activities
In accordance with the Derivatives and Hedging topic of the FASB ASC, the Company recognizes derivatives as assets or liabilities on the consolidated balance sheets at their fair value. The Company periodically enters into interest rate contracts with customers and offsetting contracts with third parties. As these interest rate contracts are not designated as hedges under the Derivatives and Hedging topic of the FASB ASC, the changes in fair value of these instruments are recognized immediately in earnings.
Accounting Pronouncements
During the year ended December 31, 2014, the following Accounting Standards Updates were issued or became effective:
In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The Update provides U.S. GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of ASU No. 2014-15 is not expected to have a material impact on the Company’s consolidated financial statements.
In June 2014, the FASB issued 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 December 31, 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 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, but does not expect the guidance to have a material impact on the Company’s 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. Those not electing the proportional amortization method would account for such investments using the equity method or cost method. 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 adopted this ASU prospectively on December 31, 2014 as the retrospective adjustments were not material. The net investment balance at December 31, 2014 was $7.3 million. The amount of affordable housing tax credits recognized during 2014 was $1.5 million. Using the proportional amortization method, the amount recognized as a component of income tax expense for 2014 was $2.0 million, inclusive of the adjustment made to remove the previously recorded deferred tax asset. Prior to adopting this guidance, the Company accounted for such investments using the equity method. Under the equity method, the Company would have recognized $1.1 million as a component of other noninterest expense. Adoption of this ASU did not have a material impact on the Company's consolidated financial statements.
Business Combinations

Business Combinations
Intermountain Community Bancorp
On November 1, 2014, the Company completed its acquisition of Intermountain Community Bancorp and its wholly-owned banking subsidiary Panhandle State Bank ("Intermountain"). The Company acquired 100% of the voting 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 (formerly the purchase method). The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the November 1, 2014 acquisition date. Initial accounting for deferred taxes was incomplete as of December 31, 2014. The amount currently recognized in the financial statements has been determined provisionally as the final Intermountain Community Bancorp tax return has not yet been completed. The application of the acquisition method of accounting resulted in the recognition of goodwill of $38.6 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 estimated fair value of the net assets acquired. 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 November 1, 2014 to December 31, 2014. 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.
The following table presents certain unaudited pro forma information for illustrative purposes only, for the years ended December 31, 2014 and 2013 as if Intermountain had been acquired on January 1, 2013. This unaudited estimated pro forma financial 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 periods. The pro forma information is not indicative of what would have occurred had the acquisition occurred on January 1, 2013. In particular, no adjustments have been made to eliminate the impact of other-than-temporary impairment losses and losses recognized on the sale of securities that may not have been necessary had the investment securities been recorded at fair value as of January 1, 2013. 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.

West Coast Bancorp
On April 1, 2013, the Company completed its acquisition of West Coast Bancorp (“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 December 31, 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 illustrative purposes only, for the years ended December 31, 2013 and 2012 as if West Coast had been acquired on January 1, 2012. 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 on January 1, 2012. 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 on January 1, 2012. 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.

At December 31, 2014, there were 125 U.S. government agency and government-sponsored enterprise mortgage-backed securities and collateralized mortgage obligations securities in an unrealized loss position, of which 43 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 December 31, 2014.
At December 31, 2014, there were 95 state and municipal government securities in an unrealized loss position, of which 44 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 December 31, 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 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 December 31, 2014.
At December 31, 2014, there were 34 U.S. government agency and government-sponsored enterprise securities in an unrealized loss position, of which 17 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 December 31, 2014.
At December 31, 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 December 31, 2014.
At December 31, 2014, there were two other securities in an unrealized loss position, of which one security, a mortgage-backed securities fund 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 December 31, 2014 as it has the intent and ability to hold the investment for sufficient time to allow for recovery in the market value.
Securities Deemed to be Other-Than-Temporarily Impaired
During the fourth quarter of 2012, the Company received full payment on a municipal bond that was determined to be other-than-temporarily impaired during 2011 for which the Company recorded impairment of $3.0 million in 2011. The 2012 gain related to this security is recorded in the line item Investment securities gains(losses), net in the Consolidated Statements of Income.

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 Company had no commitments to lend additional funds on loans classified as TDR as of December 31, 2014 and 2013. 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. 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 did not have any loans modified as TDR that defaulted within 12 months of being modified as TDR during the years ended December 31,
2014, 2013, and 2012.
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 acquired 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 Commitments and Letters of Credit
Allowance for Loan and Lease Losses and Unfunded Loan Commitments and Letters of Credit
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 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. 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 2014, 2013 and 2012. 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 allowance for loan losses 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 allowance for loan losses, 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 allowance for loan losses is estimated in a similar manner as the loan portfolio, 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, 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.

FDIC Loss-sharing Asset and Covered Assets
Covered Assets and FDIC Loss sharing Asset
FDIC Loss-sharing Asset and Covered Assets
We are a party to four loss sharing agreements with the FDIC. Such agreements cover a substantial portion of losses incurred on acquired covered loans and other real estate owned. 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 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 December 31, 2014 and 2013, the net present value of the Bank’s estimated clawback liability is $4.2 million and $3.9 million, respectively, which is included in other liabilities on the consolidated balance sheet.
At December 31, 2014 and 2013, the FDIC loss-sharing asset is comprised of an FDIC indemnification asset of $13.1 million and $37.9 million, respectively, and an FDIC receivable of $2.1 million and $2.0 million, respectively. 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 purchased credit impaired 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 years ending December 31, 2014 and 2013:

Goodwill and Intangible Assets
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 and between annual tests in certain circumstances such as upon 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, 2014 and concluded that there was no impairment. As of December 31, 2014 we determined there were no events or circumstances which would more likely than not reduce the fair value of our reporting unit below its carrying amount.
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.

Securities Sold Under Agreements to Repurchase
Securities sold under agreements to repurchase
Securities Sold Under Agreements to Repurchase - Term
The Company has entered into wholesale repurchase agreements with certain brokers. At December 31, 2014 and 2013, the Company held $25.0 million in wholesale repurchase agreements with an interest rate of 1.88%. Securities available for sale with a carrying amount of $28.4 million at December 31, 2014 were pledged as collateral for the repurchase agreement borrowings. The broker holds the securities while the Company continues to receive the principal and interest payments from the securities. Upon maturity of the agreement in 2018, the pledged securities will be returned to the Company.
Securities Sold Under Agreements to Repurchase - Sweep
These sweep repurchase agreements are generally short-term agreements. These agreements are treated as financing transactions and the obligations to repurchase securities sold are reflected as a liability in the consolidated financial statements. The dollar amount of securities underlying the agreements remains in the applicable asset account of the consolidated financial statements. These agreements had a balance of $80.1 million and a weighted average interest rate of 0.12% at December 31, 2014. All of these repurchase agreements in existence at December 31, 2014 mature on a daily basis. Securities available for sale with a carrying amount of $103.0 million at December 31, 2014 were pledged as collateral for the repurchase agreement borrowings related to the acquisition of Intermountain.
Other Borrowings

Other Borrowings
On November 1, 2014, with its acquisition of Intermountain, the Company assumed $16.5 million of trust preferred obligations. The Company redeemed $8.3 million of these obligations on December 26, 2014. At December 31, 2014, the remaining $8.2 million of obligations bore interest at a rate of 3.03%, paid quarterly. Subsequent to year-end, on January 7, 2015, the Company redeemed the remaining trust preferred obligations.
Derivatives and Balance Sheet Offsetting
Derivatives and Balance Sheet Offsetting
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 December 31, 2014 and 2013 was $215.6 million and $179.5 million, respectively. During 2014 a mark-to-market loss of $51 thousand was recorded to other noninterest expense. There was no earnings impact for the years ending December 31, 2013 and 2012.

The Company is party to interest rate swap agreements 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.

Employee Benefit Plans
Employee Benefit Plans
Employee Benefit Plans
401(k) Plan
The Company maintains defined contribution and profit sharing plans in conformity with the provisions of section 401(k) of the Internal Revenue Code. The Columbia Bank 401(k) and Profit Sharing Plan (the “401(k) Plan”), permits eligible Columbia Bank employees, those who are at least 18 years of age and have completed six months of service, to contribute up to 75% of their eligible compensation to the 401(k) Plan. On a per pay period basis the Company is required to match 50% of employee contributions up to 3% of each employee’s eligible compensation. The Company contributed $2.0 million during 2014, $1.9 million during 2013, and $1.4 million during 2012, in matching funds to the 401(k) Plan. Additionally, as determined annually by the board of directors of the Company, the 401(k) Plan provides for a non-matching discretionary profit sharing contribution. The Company’s discretionary profit sharing contributions were $4.4 million during 2014, $4.0 million during 2013 and $2.9 million during 2012.
Employee Stock Purchase Plan
The Company maintains an “Employee Stock Purchase Plan” (the “ESP Plan”) in which substantially all employees of the Company are eligible to participate. The ESP Plan provides participants the opportunity to purchase common stock of the Company at a discounted price. Under the ESP Plan, participants can purchase common stock of the Company for 90% of the lowest price on either the first or last day in each of two six month look-back periods. The look-back periods are January 1st through June 30th and July 1st through December 31st of each calendar year. The 10% discount is recognized by the Company as compensation expense and does not have a material impact on net income or earnings per common share. Participants of the ESP Plan purchased 34,168 shares for $904 thousand in 2014, 32,598 shares for $686 thousand in 2013 and 39,393 shares for $725 thousand in 2012. At December 31, 2014 there were 541,744 shares available for purchase under the ESP plan.
Supplemental Compensation Plan
The Company maintains supplemental compensation arrangements (“Unit Plans”) to provide benefits for certain employees. The Unit Plans generally vest over a 4-10 year period and provide a fixed annual benefit over a 5-10 year period. At December 31, 2014 and 2013 the liability associated with these plans was $4.8 million and $4.7 million, respectively. Expense associated with these plans for the years ended December 31, 2014, 2013 and 2012 was $588 thousand, $458 thousand and $677 thousand, respectively.
Supplemental Executive Retirement Plan
The Company maintains a supplemental executive retirement plan (the “SERP”), a nonqualified deferred compensation plan that provides retirement benefits to certain highly compensated executives. The SERP is unsecured and unfunded and there are no program assets. The SERP projected benefit obligation, which represents the vested net present value of future payments to individuals under the plan is accrued over the estimated remaining term of employment of the participants and has been determined by actuarial valuation using the “RP-2000 Annuity Mortality Table” for the mortality assumptions and discount rate of 5.10% for both 2014 and 2013. Additional assumptions and features of the plan are a normal retirement age of 65 and a 2% annual cost of living benefit adjustment. The projected benefit obligation is included in other liabilities on the Consolidated Balance Sheets.
The following table reconciles the accumulated liability for the projected benefit obligation:

Total rental expense on buildings and equipment, net of rental income of $756 thousand, $673 thousand and $639 thousand, was $8.3 million, $8.5 million and $4.5 million, for the years ended December 31, 2014, 2013 and 2012, respectively.
Financial Instruments with Off-Balance Sheet Risk: In the normal course of business, the Company makes loan commitments (typically unfunded loans and unused lines of credit) and issues standby letters of credit to accommodate the financial needs of its customers.
Standby letters of credit commit the Company to make payments on behalf of customers under specified conditions. Historically, no significant losses have been incurred by the Company under standby letters of credit. Both arrangements have credit risk essentially the same as that involved in extending loans to customers and are subject to the Company’s normal credit policies, including collateral requirements, where appropriate. At December 31, 2014 and 2013, the Company’s loan commitments amounted to $1.58 billion and $1.37 billion, respectively. Standby letters of credit were $36.7 million at both December 31, 2014 and 2013. In addition, commitments under commercial letters of credit used to facilitate customers’ trade transactions and other off-balance sheet liabilities amounted to $4.4 million and $2.7 million at December 31, 2014 and 2013, respectively.
Legal Proceedings: The Company and its subsidiaries are from time to time defendants in and are threatened with various legal proceedings arising from their regular business activities. Management, after consulting with legal counsel, is of the opinion that the ultimate liability, if any, resulting from these pending or threatened actions and proceedings will not have a material effect on the financial statements of the Company.

Shareholders' Equity
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 the Class C Warrants previously issued by West Coast. The Warrants were immediately exercisable and will expire on October 23, 2016. At December 31, 2014, there were no remaining warrants outstanding. During the year ended December 31, 2014, 1,722,497 common shares were issued from the exercise of warrants.
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 as of the close of business on February 5, 2014.
On April 23, 2014 the Company declared a quarterly cash dividend of $0.12 per common share and common share equivalent for holders of preferred stock, and a special 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.
On July 23, 2014 the Company declared a quarterly cash dividend of $0.14 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 August 20, 2014 to shareholders of record at the close of business August 6, 2014.
On October 23, 2014 the Company declared a quarterly cash dividend of $0.16 per 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 November 19, 2014 to shareholders of record at the close of business October 31, 2014.
Subsequent to year end, on January 29, 2015 the Company declared a quarterly cash dividend of $0.16 per share and common share equivalent for holders of preferred stock, and a special cash dividend of $0.14, both payable on February 25, 2015, to shareholders of record at the close of business on February 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.
Stock Repurchase Program
In 2011, the board of directors authorized the repurchase of 2 million shares of Columbia common stock. The Company may purchase the shares from time to time in the open market or in private transactions, under conditions which allow such repurchases to be accretive to earnings per share while maintaining capital ratios that exceed the guidelines for a well-capitalized financial institution. No shares were repurchased under the stock repurchase program during 2014, 2013 or 2012.
Fair Value Accounting and Measurement
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 December 31, 2014 and 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 years ended December 31, 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 —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 recorded at the lower of the 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 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 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 table sets forth the Company’s assets that were measured using fair value estimates on a nonrecurring basis during the years ended December 31, 2014 and 2013:

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 December 31, 2014 or 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 purchased credit impaired loans, fair value is estimated by discounting the expected future cash flows using a lending rate that would have been offered on December 31, 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 contracts 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. Subsequent to year-end, on January 7, 2015, the Company redeemed these trust preferred obligations (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.

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 periods indicated:

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.
Share-Based Payments
Share-Based Payments
Share-Based Payments
At December 31, 2014, the Company had one equity compensation plan (the “Plan”), which is shareholder approved, that provides for the granting of share options and shares to eligible employees and directors up to 1,800,000 shares.
Share Awards: Restricted share awards provide for the immediate issuance of shares of Company common stock to the recipient, with such shares held in escrow until certain service conditions are met, generally four years of continual service. Recipients of restricted shares do not pay any cash consideration to the Company for the shares, have the right to vote all shares subject to such grant, and receive all dividends with respect to such shares, whether or not the shares have vested. The fair value of share awards is equal to the fair market value of the Company’s common stock on the date of grant.
A summary of changes in the Company’s nonvested shares and related information for the years ended December 31, 2014, 2013 and 2012 is presented below:

As of December 31, 2014, there was $7.0 million of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the Plan. That cost is expected to be recognized over a weighted average period of 2.4 years. The total fair value, as measured on the date of vesting, of shares vested during the years ended December 31, 2014, 2013, and 2012 was $2.3 million, $2.5 million, and $2.5 million, respectively.
Share Options: Option awards are generally granted with an exercise price equal to the market price of the Company’s stock at the date of grant; those option awards generally vest based on three years of continual service and are exercisable for a five-year period after vesting. Option awards granted have a 10-year maximum term.
The fair value of each option award is estimated on the date of grant using the Black-Scholes option valuation model. The fair value of all options is amortized on a straight-line basis over the requisite service periods, which are generally the vesting periods. The expected life of options granted represents the period of time that they are expected to be outstanding. The expected life is determined based on historical experience with similar awards, giving consideration to the contractual terms and vesting schedules. Expected volatilities of our common stock are estimated at the date of grant based on the historical volatility of the stock. The volatility factor is based on historical stock prices over the most recent period commensurate with the estimated expected life of the award. The risk-free interest rate is based on the U.S. Treasury curve in effect at the time of the award. The expected dividend yield is based on dividend trends and the market value of the Company’s stock price at the time of the award.

(1) Reclassified to conform to current period presentation. The reclassification was limited to including previously reported amounts for tax credits in the row for other, net.
As of December 31, 2014 and 2013, we had no unrecognized tax benefits. There were no amounts related to interest and penalties recognized for the years ended December 31, 2014 and 2013. The tax years subject to examination by federal and state taxing authorities are the years ending December 31, 2014, 2013, 2012 and 2011. As a result of recent acquisitions, the Company has net operating loss carryforwards in the federal, Idaho and Oregon jurisdictions of of $30.7 million, $38.1 million and $13.5 million , respectively, which begin to expire in 2024 and federal and Oregon credit carryforwards of $561 thousand and $1.6 million, respectively. Federal credit carryforwards related to alternative minimum taxes, and have no expiration, while the Oregon credit carryforwards begin to expire in 2015. The amount of carryforwards that may be utilized annually is limited under Sections 382 and 383 as a result of changes in control. Management believes that these carryforwards will be used in the normal course of business, and as such, has not recorded a valuation allowance.
Regulatory Capital Requirements
Regulatory Capital Requirements
Regulatory Capital Requirements
The Company (on a consolidated basis) and its banking subsidiary are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company and its banking subsidiary’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and its banking subsidiary must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies.
Quantitative measures established by regulation to ensure capital adequacy require the Company and its banking subsidiary to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital to risk-weighted assets (as defined in the regulations) and of Tier 1 capital to average assets (as defined in the regulations). Management believes, as of December 31, 2014 and 2013, that the Company and Columbia Bank met all capital adequacy requirements to which they are subject.
As of December 31, 2014, the most recent notification from the Federal Deposit Insurance Corporation categorized Columbia Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following tables. There are no conditions or events since the notification that management believes have changed Columbia Bank’s category. The Company and its banking subsidiary’s actual capital amounts and ratios as of December 31, 2014 and 2013, are also presented in the following table.

Branch Sales
On August 23, 2014, Columbia completed a branch sale transaction to Sound Community Bank. In the transaction, Columbia sold three branches and related assets and deposit liabilities to Sound Community Bank. 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.

Summary of Significant Accounting Policies (Policies)
Cash and cash equivalents 
Cash and cash equivalents
Cash and cash equivalents include cash and due from banks, and interest bearing balances due from correspondent banks and the Federal Reserve Bank. Cash and cash equivalents have a maturity of 90 days or less at the time of purchase.
Securities 
Securities
Securities are classified based on management’s intention on the date of purchase. All securities are classified as available for sale and are presented at fair value. Unrealized gains or losses on securities available for sale are excluded from net income but are included as separate components of other comprehensive income, net of taxes. Purchase premiums or discounts on securities available for sale are amortized or accreted into income using the interest method over the terms of the individual securities. The Company performs a quarterly assessment to determine whether a decline in fair value below amortized cost is other-than-temporary. Amortized cost includes adjustments made to the cost of an investment for accretion, amortization, collection of cash and previous other-than temporary impairment recognized in earnings. Other-than-temporary impairment exists when it is probable that the Company will be unable to recover the entire amortized cost basis of the security.
In performing the quarterly assessment for debt securities, management considers whether or not the Company expects to recover the entire amortized cost basis of the security. In addition, management also considers whether it is more likely than not that it will not have to sell the security before recovery of its cost basis. If the Company intends to sell a security or it is more likely than not it will be required to sell a security prior to recovery of its cost basis, the entire amount of impairment is recognized in earnings. If the Company does not intend to sell the security or it is not more likely than not it will be required to sell the security prior to recovery of its cost basis, the credit loss component of impairment is recognized in earnings and impairment associated with non-credit factors, such as market liquidity, is recognized in other comprehensive income net of tax. A credit loss is the difference between the cost basis of the security and the present value of cash flows expected to be collected, discounted at the security’s effective interest rate at the date of acquisition. The cost basis of an other-than-temporarily impaired security is written down by the amount of impairment recognized in earnings. The new cost basis is not adjusted for subsequent recoveries in fair value. However, the difference between the new amortized cost basis and the cash flows expected to be collected is accreted as interest income. The total other-than-temporary impairment, if any, is presented in the consolidated statements of income with a reduction for the amount of other-than-temporary impairment that is recognized in other comprehensive income, if any.
Realized gains or losses on sales of securities available for sale are recorded using the specific identification method.
Federal Home Loan Bank Stock 
Federal Home Loan Bank Stock
The Company’s investment in Federal Home Loan Bank (“FHLB”) stock is carried at par value because the shares can only be redeemed with the FHLB at par. The Company is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages and FHLB advances. Stock redemptions are at the discretion of the FHLB or of the Company, upon five years’ prior notice for FHLB Class B stock or six months notice for FHLB Class A stock to the FHLB. FHLB stock is subject to recoverability testing per the Financial Services—Depository and Lending topic of the FASB Accounting Standards Codification (“ASC”).
Loans 
Loans, excluding purchased credit impaired loans are generally carried at the unpaid principal balance, net of premiums, unearned discounts and net deferred loan fees. Net deferred loan fees include deferred unamortized fees less direct incremental loan origination costs. Net deferred loan fees, premiums and unearned discounts are amortized into interest income using either the interest method or straight-line method over the terms of the loans, adjusted for actual prepayments. The amortization is calculated using the interest method for all loans except revolving loans, for which the straight-line method is used. Interest income is accrued as earned. Fees related to lending activities other than the origination or purchase of loans are recognized as noninterest income during the period the related services are performed.
Nonaccrual loans—Loans are placed on nonaccrual status when a loan becomes contractually past due 90 days with respect to interest or principal unless the loan is both well secured and in the process of collection, or if full collection of interest or principal becomes uncertain. When a loan is placed on nonaccrual status, any accrued and unpaid interest receivable is reversed and the recognition of net deferred loan fees, premiums and unearned discounts ceases. Thereafter, interest collected on the loan is accounted for on the cash collection or cost recovery method until qualifying for return to accrual status. Generally, a loan may be returned to accrual status when the delinquent principal and interest are brought current in accordance with the terms of the loan agreement for a minimum period of six months and future payments are reasonably assured.
Impaired loans—Loans are considered impaired when based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement or when a loan has been modified in a troubled debt restructuring. The assessment for impairment occurs when and while such loans are designated as classified per the Company’s internal risk rating system or when and while such loans are on nonaccrual. All nonaccrual loans greater than $500,000 and all troubled debt restructured loans are considered impaired and analyzed individually on a quarterly basis. Classified loans with an outstanding balance greater than $500,000 are evaluated for potential impairment on a quarterly basis.
When a loan with unique risk characteristics has been identified as being impaired, the amount of impairment will be measured by the Company using discounted cash flows, except when it is determined that the remaining source of repayment for the loan is the operation or liquidation of the underlying collateral. In these cases, the current fair value of the collateral, reduced by costs to sell, will be used in place of discounted cash flows. As a final alternative, the observable market price of the debt may be used to assess impairment. Predominantly, the Company uses the fair value of collateral approach based upon a reliable valuation.
When the measurement of the impaired loan is less than the recorded amount of the loan, an impairment is recognized by recording a charge-off to the allowance for loan and lease losses or by designating a specific reserve. The Company’s policy is to record cash receipts received on impaired loans first as reductions to principal and then to interest income.
Restructured Loans—A loan is classified as a troubled debt restructuring when a borrower is experiencing financial difficulties that lead to a restructuring of the loan, and the Company grants concessions to the borrower in the restructuring that it would not otherwise consider. These concessions may include interest rate reductions, principal forgiveness, extension of maturity date and other actions intended to minimize potential losses. Generally, a nonaccrual loan that is restructured remains on nonaccrual status for a period of six months to demonstrate that the borrower can meet the restructured terms. If the borrower’s performance under the new terms is not reasonably assured, the loan remains classified as a nonaccrual loan.
Purchased Credit Impaired Loans (“PCI Loans”)—Loans acquired with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are accounted for under ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, formerly SOP 03-3 Accounting for Certain Loans or Debt Securities Acquired in a Transfer. In addition, because of the significant discounts associated with certain of the acquired loan portfolios, the Company elected to account for those certain acquired loans under ASC 310-30.
In situations where such loans have similar risk characteristics, loans are aggregated into pools to estimate cash flows. A pool is accounted for as a single asset with a single interest rate, cumulative loss rate and cash flow expectation. Expected cash flows at the acquisition date in excess of the fair value of loans are considered to be accretable yield, which is recognized as interest income over the life of the loan pool using a level yield method if the timing and amount of the future cash flows of the pool is reasonably estimable. Subsequent to the acquisition date, any increases in cash flow over those expected at purchase date in excess of fair value are recorded as interest income prospectively. Any subsequent decreases in cash flow over those expected at purchase date due to credit deterioration are recognized by recording an allowance for losses on purchased credit impaired loans. Any disposals of loans, including sales of loans, payments in full or foreclosures result in the removal of the loan from the loan pool at the carrying amount.
Unfunded loan commitments—Unfunded commitments are generally related to providing credit facilities to clients of the Bank and are not actively traded financial instruments. These unfunded commitments are disclosed as financial instruments with off-balance sheet risk in Note 17 in the Notes to Consolidated Financial Statements.
Allowance for Loan and Lease Losses 
Allowance for Loan and Lease Losses
The Company accounts for the credit risk associated with lending activities through its allowance for loan and lease losses and provision for loan and lease losses. The provision is the expense recognized in the consolidated statements of income to adjust the allowance to the levels deemed appropriate by management, as determined through application of the Company’s allowance methodology procedures. The provision for loan and lease losses reflects management’s judgment of the adequacy of the allowance for loan and lease losses. Loan and lease losses are charged against the allowance when management believes the collectability of a loan balance is unlikely. Subsequent recoveries, if any, are credited to the allowance.
The allowance for loan and lease losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, and estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.
The allowance consists of general, specific, and unallocated components. The general component covers loans not specifically measured for impairment and is based on historical loss experience adjusted for qualitative factors. The specific component relates to loans that are impaired. For impaired loans an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The unallocated allowance provides for other credit losses inherent in the Company’s 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 periodically based on trends in credit losses, the results of credit reviews and overall economic trends.
Allowance for Unfunded Commitments and Letters of Credit 
Allowance for Unfunded Commitments and Letters of Credit
The allowance for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to these unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. The allowance for unfunded commitments is included in other liabilities on the consolidated balance sheets, with changes to the balance charged against noninterest expense.
Premises and Equipment 
Premises and Equipment
Land, buildings, leasehold improvements and equipment are stated at cost less accumulated depreciation and amortization. Gains or losses on dispositions are reflected in current operations. Expenditures for improvements and major renewals are capitalized, and ordinary maintenance, repairs and small purchases are charged to operating expenses. Depreciation and amortization are computed based on the straight-line method over the estimated useful lives of the various classes of assets. The ranges of useful lives for the principal classes of assets are as follows:
Buildings and building improvements
5 to 39 years
Leasehold improvements
Term of lease or useful life, whichever is shorter
Furniture, fixtures and equipment
3 to 7 years
Vehicles
5 years
Computer software
3 to 5 years
Software 
Software
Capitalized software is stated at cost, less accumulated amortization. Amortization is computed on a straight-line basis and charged to expense over the estimated useful life of the software which is generally three years. Capitalized software is included in Premises and equipment, net in the consolidated balance sheets.
Other Real Estate Owned—Noncovered 
Other Real Estate Owned
OREO is composed of real estate acquired in satisfaction of loans. Properties acquired by foreclosure or deed in lieu of foreclosure are transferred to OREO and are recorded at fair value less estimated costs to sell, at the date of transfer of the property. If the carrying value exceeds the fair value at the time of the transfer, the difference is charged to the allowance for loan and lease losses. The fair value of the OREO property is based upon current appraisal. Losses that result from the ongoing periodic valuation of these properties are charged to the net cost of operation of OREO in the period in which they are identified. Improvements to the OREO are capitalized and holding costs are charged to the net cost of operation of OREO as incurred.
Covered Assets and Related FDIC Loss Sharing Asset 
FDIC Loss-sharing Asset
The acquisition date fair value of the reimbursement the Company expected to receive from the FDIC under loss-sharing agreements was recorded in the FDIC loss-sharing asset on the consolidated balance sheet. Subsequent to initial recognition, the FDIC loss-sharing 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 assets. Any decrease in expected cash flows for the covered assets due to an increase in expected credit losses will increase the FDIC loss-sharing asset and any increase in expected future cash flows for the covered assets due to a decrease in expected credit losses will decrease the FDIC loss-sharing 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.
Goodwill and Intangibles 
Goodwill and Intangibles
Net assets of companies acquired in purchase transactions are recorded at fair value at the date of acquisition. Identified intangibles are amortized on an accelerated basis over the period benefited. Goodwill is not amortized but is reviewed for potential impairment during the third quarter on an annual basis or, more frequently, if events or circumstances indicate a potential impairment, at the reporting unit level. A reporting unit is an operating segment or one level below an operating segment for which discrete financial information is available and regularly reviewed by management. The Company consists of a single reporting unit. If the fair value of the reporting unit, including goodwill, is determined to be less than the carrying amount of the reporting unit, a further test is required to measure the amount of impairment. If an impairment loss exists, the carrying amount of goodwill is adjusted to a new cost basis. Subsequent reversal of a previously recognized goodwill impairment loss is prohibited.
Intangible assets are evaluated for impairment if events and circumstances indicate a possible impairment. Such evaluation of other intangible assets is based on undiscounted cash flow projections. At December 31, 2014, intangible assets included on the consolidated balance sheets principally consists of a core deposit intangible amortized using an accelerated method with an original estimated life 10 years.
Income Taxes 
Income Taxes
The provision for income taxes includes current and deferred income tax expense on net income adjusted for permanent and temporary differences such as interest income on state and municipal securities and affordable housing credits. Deferred tax assets and liabilities are recognized for the expected future tax consequences of existing temporary differences between the financial reporting and tax reporting basis of assets and liabilities using enacted tax laws and rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. On a quarterly basis, management evaluates deferred tax assets to determine if these tax benefits are expected to be realized in future periods. This determination is based on facts and circumstances, including the Company’s current and future tax outlook. To the extent a deferred tax asset is no longer considered “more likely than not” to be realized, a valuation allowance is established.
Earnings per Common Share 
Earnings per Common Share
The Company’s capital structure includes convertible preferred shares, common shares, restricted common shares, common share options, and during portions of 2014 and 2013, warrants to purchase common shares. Restricted common shares participate in dividends declared on common shares at the same rate as common shares. Preferred shares participate in dividends declared on common shares on an “as if converted” basis. Accordingly, the Company calculates earnings per common share (“EPS”) using the two-class method under the Earnings per Share topic of the FASB ASC. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common shareholders but does not require the presentation of basic and diluted EPS for securities other than common shares.
Under the two-class method, basic EPS is computed by dividing earnings allocated to common shareholders by the weighted average number of common shares outstanding for the period. Earnings allocated to common shareholders represents net income reduced by earnings allocated to participating securities. Participating securities include nonvested restricted stock awards and preferred stock. Diluted EPS is computed in the same manner as basic earnings per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if certain shares issuable upon exercise of options and warrants were included unless those additional shares would have been anti-dilutive. For the diluted EPS computation, the treasury stock method is applied and compared to the two-class method and whichever method results in a more dilutive impact is utilized to calculate diluted EPS.

The Company accounts for stock options and stock awards in accordance with the Compensation—Stock Compensation topic of the FASB ASC. Authoritative guidance requires the Company to measure the cost of employee services received in exchange for an award of equity instruments, such as stock options or stock awards, based on the fair value of the award on the grant date. This cost must be recognized in the consolidated statements of income over the vesting period of the award.
The Company issues restricted stock awards which generally vest over a four- or five-year period during which time the holder receives dividends and has full voting rights. Restricted stock is valued at the closing price of the Company’s stock on the date of an award.
Derivatives and Hedging Activities 
Derivatives and Hedging Activities
In accordance with the Derivatives and Hedging topic of the FASB ASC, the Company recognizes derivatives as assets or liabilities on the consolidated balance sheets at their fair value. The Company periodically enters into interest rate contracts with customers and offsetting contracts with third parties. As these interest rate contracts are not designated as hedges under the Derivatives and Hedging topic of the FASB ASC, the changes in fair value of these instruments are recognized immediately in earnings.
Allowance for Loan and Lease Losses 
Allowance for Loan Losses on Purchased Credit Impaired Loans
The Company updates its cash flow projections for purchased credit impaired loans accounted for under ASC 310-30 on a quarterly basis. Assumptions utilized in this process include projections related to probability of default, loss severity, prepayment and recovery lag. Projections related to probability of default and prepayment are calculated utilizing a loan migration analysis. The loan migration analysis is a matrix of probability that is used to estimate the probability of a loan pool transitioning into a particular delinquency state 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.
Any decreases in expected cash flows after the acquisition date and subsequent measurement periods are recognized by recording a provision for loan losses. See Purchased Credit Impaired Loans for further discussion.

Business Acquisition, Pro Forma Information [Table Text Block] 
The following table presents certain unaudited pro forma information for illustrative purposes only, for the years ended December 31, 2014 and 2013 as if Intermountain had been acquired on January 1, 2013. This unaudited estimated pro forma financial 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 periods. The pro forma information is not indicative of what would have occurred had the acquisition occurred on January 1, 2013. In particular, no adjustments have been made to eliminate the impact of other-than-temporary impairment losses and losses recognized on the sale of securities that may not have been necessary had the investment securities been recorded at fair value as of January 1, 2013. 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.
