NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Columbia Banking System, Inc.


1.	Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The interim unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X. The consolidated financial statements include the accounts of the Company, and its wholly owned banking subsidiary Columbia Bank (the “Bank”), and West Coast Trust. All intercompany transactions and accounts have been eliminated in consolidation. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of the results for the interim periods presented have been included. The results of operations for the nine months ended September 30, 2013 are not necessarily indicative of results to be anticipated for the year ending December 31, 2013 . The accompanying interim unaudited consolidated financial statements should be read in conjunction with the financial statements and related notes contained in the Company’s 2012 Annual Report on Form 10-K.

Significant Accounting Policies

The significant accounting policies used in preparation of our consolidated financial statements are disclosed in our 2012 Annual Report on Form 10-K. There have not been any changes in our significant accounting policies compared to those contained in our 2012 Form 10-K disclosure for the year ended December 31, 2012 , except for the adoption of ASU 2012-06 as noted below.


2.	Accounting Pronouncements Recently Issued

In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The Update clarifies when it is appropriate for an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. ASU 2013-11 is effective for interim and annual periods beginning after December 15, 2013. Early adoption is permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date, however, retrospective application is also permitted. Adoption of the new guidance is not expected to have a significant impact on the Company's consolidated financial statements.

In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income . The Update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and to present either on the face of the statement where net income is presented, or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. The amendments are effective for annual and interim reporting periods beginning on or after December 15, 2012. The Company adopted the ASU 2013-02 reporting requirements during the interim reporting period beginning on January 1, 2013 with no impact to the Company's financial condition or results of operations. See Note 12 to the Consolidated Financial Statements of this report for new disclosures related to accumulated other comprehensive income.

In October 2012, the FASB issued 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. ASU 2012-06 clarifies that when a reporting entity recognizes an indemnification asset as a result of a government-assisted acquisition of a financial institution and there is a subsequent change in the amount of cash flows expected to be collected on the indemnified asset, the reporting entity should subsequently measure the indemnification asset on the same basis as the underlying loans by taking into account the contractual limitations of the Loss-Sharing Agreement ("LSA"). For amortization of changes in value, the reporting entity should use the term of the indemnification agreement if it is shorter than the term of the acquired loans. ASU 2012-06 is effective for interim and annual periods beginning after December 15, 2012. The Company adopted the ASU as of January 1, 2013. As a result of the adoption of the ASU, an additional $9.9 million of indemnification asset amortization was recorded during the nine months ending September 30, 2013 , resulting in a reduction of $6.4 million in net income and $0.13 in diluted earnings per share.

3.	Business Combinations

West Coast Bancorp

On April 1, 2013 , the Company completed its acquisition of West Coast Bancorp ("West Coast"). The Company acquired 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 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 April 1, 2013 acquisition date. The amounts for other assets, other liabilities and goodwill have been retrospectively adjusted during the current period to reflect the removal of a liability that was recorded by West Coast, as well as the associated impacts to the deferred tax asset (other assets) and goodwill. The adjustment recorded in the current period was a decrease to other liabilities of $1.8 million , a decrease to other assets of $622 thousand and a decrease to goodwill of $1.1 million and no impact to previously reported net income. Initial accounting for deferred taxes, the mortgage repurchase liability and payment system intangible remain incomplete as of September 30, 2013. The amounts currently recognized in the financial statements have been determined provisionally as the completion of a fair value analysis for these items is still in progress.

The application of the acquisition method of accounting resulted in the recognition of goodwill of $229.7 million and a core deposit intangible of $15.3 million , or 0.89% 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 table below summarizes the amounts recognized as of the acquisition date for each major class of assets acquired and liabilities assumed:



	April 1, 2013
	(in thousands)

Purchase price as of April 1, 2013	$	540,791
Recognized amounts of identifiable assets acquired and (liabilities assumed), at fair value:
Cash and cash equivalents	$	110,440
Investment securities	730,842
Federal Home Loan Bank stock	11,824
Acquired loans	1,407,798
Premises and equipment	35,884
Other real estate owned	14,708
Core deposit intangible	15,257
Other assets	76,088
Deposits	(1,883,407		)
Federal Home Loan Bank advances	(128,885		)
Junior subordinated debentures	(51,000		)
Other liabilities	(28,435		)
Total fair value of identifiable net assets	311,114
Goodwill	$	229,677

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

The operating results of the Company include the operating results produced by the acquired assets and assumed liabilities for the period April 1, 2013 to September 30, 2013 . 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.

Table of Contents

The following table presents certain unaudited pro forma information for illustrative purposes only, for the nine month periods ended September 30, 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 investments securities been recorded at fair value as of 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 will differ from the unaudited pro forma information presented.



	Unaudited Pro Forma

Table of Contents

At September 30, 2013 , there were 67 U.S. government agency and government-sponsored enterprise mortgage-backed securities & collateralized mortgage obligations securities in an unrealized loss position, of which six were in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where these investments fall within the yield curve and their individual characteristics. Because the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2013 .

At September 30, 2013 , there were 109 state and municipal government securities in an unrealized loss position, of which two were in a continuous loss position for 12 months or more. The unrealized losses on state and municipal securities were caused by interest rate changes or widening of market spreads subsequent to the purchase of the individual securities. Management monitors published credit ratings of these securities for adverse changes. As of September 30, 2013 , none of the rated obligations of state and local government entities held by the Company had a below investment grade credit rating. Because the credit quality of these securities are investment grade and the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2013 .

At September 30, 2013 , there were 29 U.S. government agency and government-sponsored enterprise securities in an unrealized loss position, none 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 maturity, the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2013 .

At September 30, 2013 , there were four U.S. government securities in an unrealized loss position, none 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 this security nor does the Company consider it more likely than not that it will be required to sell this security before the recovery of amortized cost basis, which may be maturity, the Company does not consider this investment to be other-than-temporarily impaired at September 30, 2013 .

At September 30, 2013 , 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 September 30, 2013 as it has the intent and ability to hold the investment for sufficient time to allow for recovery in the market value.

There were no Troubled Debt Restructurings ("TDR") during the three months ended September 30, 2013 or nine months ended September 30, 2012 . The following is an analysis of loans classified as TDR during the nine months ended September 30, 2013 :

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 commitments to lend $1.7 million and $236 thousand of additional funds on loans classified as TDR as of September 30, 2013 and December 31, 2012 , respectively. 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 within the past twelve months that have defaulted during the nine months ended September 30, 2013 .


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

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


1.	General valuation allowance consistent with the Contingencies topic of the FASB Accounting Standards Codification ("ASC").


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


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

The general valuation allowance is systematically calculated quarterly using quantitative and qualitative information about specific loan classes. The minimum required level 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.

The $4.3 million provision expense reflects a change in estimate for the allowance for loan losses for loans acquired in the West Coast Bank transaction. The change was the result of moving from the initial fair value accounting for those loans, which included a net loan discount of $88.8 million , to our standard allowance methodology. Our standard allowance methodology takes into account the $19.7 million in net loan discount accretion recorded in earnings subsequent to the acquisition. The provision resulted in a $2.8 million reduction to net income and reduced earnings per diluted common share by $0.05 and $0.06 for the current quarter and year-to-date period, respectively.

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

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

We have used the same methodology for ALLL calculations during the nine months ended September 30, 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 prudently adjust our ALLL as necessary in order to maintain adequate reserves. The Company carefully monitors the loan portfolio and continues to emphasize the importance of credit quality.

Risk Elements

The extension of credit in the form of loans to individuals and businesses is one of our principal commerce 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.

8. Covered Assets and FDIC Loss-sharing Asset

Covered Assets

Covered assets consist of loans and OREO acquired in certain FDIC-assisted acquisitions during 2010 and 2011, for which the Bank entered into loss-sharing agreements, whereby the FDIC will cover a substantial portion of future losses on loans (and related unfunded loan commitments), OREO and certain accrued interest on loans during the terms of the agreements. Under the terms of the loss-sharing agreements, the FDIC will absorb 80% of losses and share in 80% of loss recoveries up to specified amounts. With respect to loss-sharing agreements for two acquisitions completed in 2010, after those specified amounts, the FDIC will absorb 95% of losses and share in 95% of loss recoveries. The loss-sharing provisions of the agreements for commercial and single-family mortgage loans are in effect for five and ten years, respectively, from the acquisition dates and the loss recovery provisions are in effect for eight and ten years, respectively, from the acquisition dates.

Ten years and forty-five days after the acquisition dates, the Bank shall 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.

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

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

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

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

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

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

During the nine months ended September 30, 2013 , the Company recorded a provision recapture for losses on covered loans of $1.7 million . Of this amount, $929 thousand was impairment recapture calculated in accordance with ASC 310-30 and $750 thousand was a provision recapture to adjust the allowance for loss calculated under ASC 450-20 for draws on acquired loans. The impact to earnings of the $1.7 million of provision recapture for covered loans was partially offset through noninterest income by a $1.3 million unfavorable adjustment to the change FDIC loss-sharing asset line item.

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

FDIC Loss-sharing Asset

At September 30, 2013 , the FDIC loss-sharing asset is comprised of a $48.4 million FDIC indemnification asset and a $5.2 million FDIC receivable. The indemnification represents the cash flows the Company expects to collect from the FDIC under the loss-sharing agreements and the FDIC receivable represents the reimbursable amounts from the FDIC that have not yet been received.

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

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

The following table shows a detailed analysis of the FDIC loss-sharing asset for the three and nine months ended September 30, 2013 and 2012 :

9.	Goodwill and Other Intangible Assets

In accordance with the Intangibles – Goodwill and Other topic of the FASB ASC, goodwill is not amortized but is reviewed for potential impairment at the reporting unit level. Management analyzes its goodwill for impairment on an annual basis on July 31 and between annual tests in certain circumstances such as material adverse changes in legal, business, regulatory and economic factors. An impairment loss is recorded to the extent that the carrying amount of goodwill exceeds its implied fair value. During the current quarter, the Company performed an impairment assessment as of July 31, 2013, and concluded that there was no impairment.

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

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

10.	Derivatives and Hedging Activities

The Company periodically enters into certain commercial loan interest rate swap agreements in order to provide commercial loan customers the ability to convert from variable to fixed interest rates. Under these agreements, the Company enters into a variable-rate loan agreement with a customer in addition to a swap agreement. This swap agreement effectively converts the customer’s variable rate loan into a fixed rate. The Company then enters into a corresponding swap agreement with a third party in order to offset its exposure on the variable and fixed components of the customer agreement. As the interest rate swap agreements with the customers and third parties are not designated as hedges under the Derivatives and Hedging topic of the FASB ASC, the instruments are marked to market in earnings. The notional amount of open interest rate swap agreements at September 30, 2013 and December 31, 2012 was $164.5 million and $177.0 million , respectively. There was no impact to the statement of income for the three or nine month periods ending September 30, 2013 and 2012 .

13.	Fair Value Accounting and Measurement

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

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

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

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

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

Fair values are determined as follows:

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

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

Table of Contents

The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis at September 30, 2013 and December 31, 2012 by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement:

Nonrecurring Measurements

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

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

Other real estate owned and other personal property owned ("OPPO") —OREO and OPPO are real and personal property that the Bank has taken ownership of in partial or full satisfaction of a loan or loans. OREO and OPPO are generally measured based on the item's fair market value as indicated by an appraisal or a letter of intent to purchase. OREO and OPPO are recorded at the lower of carrying amount or fair value less estimated costs to sell. This amount becomes the property’s new basis. Any write-downs based on the property fair value less estimated costs to sell at the date of acquisition are charged to the allowance for loan and lease losses. Management periodically reviews OREO and OPPO in an effort to ensure the property is carried at the lower of its new basis or fair value, net of estimated costs to sell. Any write-downs subsequent to acquisition are charged to earnings. The initial and subsequent write-down evaluations are performed by officers in the Special Credits group, which reports to the Chief Credit Officer. The REASD obtains appraisals from third-parties for OREO and OPPO and performs internal evaluations. If an appraisal is obtained from a third-party, the REASD reviews the appraisal to evaluate the adequacy of the appraisal report, including its scope, methods, accuracy, and reasonableness.

The following tables set forth the Company's assets that were measured using fair value estimates on a nonrecurring basis at September 30, 2013 and 2012 .

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 September 30, 2013 or December 31, 2012 , for loans which mirror the attributes of the loans with similar rate structures and average maturities. The fair values resulting from these calculations are reduced by an amount representing the change in estimated fair value attributable to changes in borrowers’ credit quality since the loans were originated. For nonperforming loans, fair value is estimated by applying a valuation discount based upon loan sales data from the FDIC. For covered loans, fair value is estimated by discounting the expected future cash flows using a lending rate that would have been offered on September 30, 2013 (Level 3).

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

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

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

FHLB advances —The fair value of Federal Home Loan Bank of Seattle (the “FHLB”) advances is estimated based on discounting the future cash flows using the market rate currently offered (Level 2).

Repurchase Agreements —The fair value of securities sold under agreement to repurchase is estimated based on discounting the future cash flows using the market rate currently offered (Level 2).

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

14.	Earnings per Common Share

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

The following table sets forth the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2013 and 2012 :

In addition to the factors set forth in the sections “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this report, the following factors, among others, could cause actual results to differ materially from the anticipated results:


•	local and national economic conditions could be less favorable than expected or could have a more direct and pronounced effect on us than expected and adversely affect our ability to continue internal growth and maintain the quality of our earning assets;


•	the local housing/real estate markets where we operate and make loans could continue to face challenges;


•	the risks presented by a continued challenging economy, including the uncertainty regarding ongoing budget talks in congress, which could adversely affect credit quality, collateral values, including real estate collateral, investment values, liquidity and loan originations and loan portfolio delinquency rates;


•	the inability to smoothly integrate West Coast Bancorp with Columbia and retain customers and employees;


•	the efficiencies and enhanced financial and operating performance we expect to realize from investments in personnel, acquisitions and infrastructure may not be realized;


•	interest rate changes could significantly reduce net interest income and negatively affect funding sources;


•	projected business increases following strategic expansion or opening of new branches could be lower than expected;


•	our reliance on FHLB advances and FRB borrowings as additional sources of short and long-term funding;


•	changes in the scope and cost of FDIC insurance and other coverages;


•	the impact of FDIC-assisted loans on our earnings;


•	changes in accounting principles, policies, and guidelines applicable to bank holding companies and banking;


•	competition among financial institutions could increase significantly;


•	consolidation in the Pacific Northwest financial services industry resulting in the creation of larger financial institutions who may have greater resources could change the competitive landscape;


•	the goodwill we have recorded in connection with acquisitions could become impaired, which may have an adverse impact on our earnings and capital;


•	the reputation of the financial services industry could deteriorate, which could adversely affect our ability to access markets for funding and to acquire and retain customers;


•	our ability to effectively manage credit risk, interest rate risk, market risk, operational risk, legal risk, liquidity risk and regulatory and compliance risk; and


•	our profitability measures could be adversely affected if we are unable to effectively manage our capital.

CRITICAL ACCOUNTING POLICIES

Management has identified the accounting policies related to the allowance for loan and lease losses, business combinations, acquired impaired loans, FDIC loss sharing asset and the valuation and recoverability of goodwill as critical to an understanding of our financial statements. These policies and related estimates are discussed in “Item 7. Management Discussion and Analysis of Financial Condition and Results of Operation” under the headings “Allowance for Loan and Lease Losses”, “Business Combinations”, “Acquired Impaired Loans”, "FDIC Loss Sharing Asset” and “Valuation and Recoverability of Goodwill” in our 2012 Annual Report on Form 10-K. There have not been any material changes in our critical accounting policies as compared to those disclosed in our 2012 Annual Report on Form 10-K.

RESULTS OF OPERATIONS

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

On April 1, 2013, the Company completed its acquisition of West Coast. The Company acquired approximately $2.63 billion in assets, including $1.41 billion in loans measured at fair value, and approximately $1.88 billion in deposits. See Note 3 to the Consolidated Financial Statements in "Item 1. Financial Statements (unaudited)" of this report for further information regarding this acquisition.

Earnings Summary

The Company reported net income for the third quarter of $13.3 million or $0.25 per diluted common share, compared to $11.9 million or $0.30 per diluted common share for the third quarter of 2012 . For the first nine months of 2013 , the Company reported net income of $40.0 million , or $0.83 per diluted common share, compared to $32.7 million , or $0.82 per diluted common share for the first nine months of 2012 .

The increase in net income for the current quarter was attributable to higher net interest income and noninterest income as a result of the West Coast acquisition, partially offset by higher provision for loan losses and higher noninterest expense due to the West Coast acquisition. The increase in net income for the current year-to-date period from the prior year periods was attributable to higher net interest income as a result of the West Coast acquisition, coupled with lower provision for loan losses, partially offset by an increase in noninterest expense due to the West Coast acquisition.

Comparison of current quarter to prior year period

Revenue (net interest income plus noninterest income) for the three months ended September 30, 2013 was $88.0 million , 56% more than the same period in 2012 . The increase in revenue was a result of higher loan interest income and noninterest income due to the West Coast acquisition. For a more complete discussion of this topic, please refer to the net interest income section contained in the ensuing pages.

The provision for loan and lease losses for the third quarter of 2013 was $4.3 million for the noncovered loan portfolio and a provision recapture of $947 thousand for the covered loan portfolio compared to a provision of $2.9 million for the noncovered loan portfolio and a provision recapture of $4.0 million for the covered loan portfolio during the third quarter of 2012 . The provision for the noncovered portfolio was the result of moving from the initial fair value accounting for the acquired West Coast loans to our standard allowance methodology and the recapture of provision for the covered loan portfolio was due to an increase in expected future cash flows as remeasured during the current quarter when compared to the prior quarter's remeasurement.

Total noninterest expense for the quarter ended September 30, 2013 was $64.7 million , up from $40.9 million for the third quarter of 2012 . The increase from the prior-year period was primarily due to acquisition-related expenses as well as ongoing noninterest expense resulting from the West Coast transaction.

Table of Contents

The increase in net income was negatively impacted by a reduction to the pretax earnings impact of the FDIC acquired loan portfolio. The following table illustrates the impact to earnings associated with the Company's FDIC acquired loan portfolios for the periods indicated:



	Three Months Ended September 30,						Nine Months Ended September 30,
	2013			2012			2012			2012

Pre-tax earnings impact of FDIC acquired loan portfolios	$	(3,362	)	$	2,580		$	(8,760	)	$	11,038

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

Revenue (net interest income plus noninterest income) for the nine months ended September 30, 2013 was $230.0 million , compared to $204.5 million for the same period in 2012 . The increase in revenue was a result of higher loan interest income and noninterest income due to the West Coast acquisition. For a more complete discussion of this topic, please refer to the net interest income section contained in the ensuing pages.

The provision for loan and lease losses for the nine months ended September 30, 2013 was $5.3 million for the noncovered loan portfolio and a provision recapture of $1.7 million for the covered loan portfolio compared to provisions of $11.1 million for the noncovered loan portfolio and $23.4 million for the covered loan portfolio during the first nine months of 2012 . The $5.3 million provision for the noncovered loan portfolio was the result of moving from the initial fair value accounting for the acquired West Coast loans to our standard allowance methodology as well as net charge offs experienced during the period. The $1.7 million in provision recapture for losses on covered loans was primarily due to increased expected future cash flows as remeasured during the current period when compared to the prior period's remeasurement.

Total noninterest expense for the nine months ended September 30, 2013 was $167.3 million , a 34% increase from the first nine months of 2012 . The increase from the prior-year period was primarily due to acquisition-related expenses as well as ongoing noninterest expense resulting from the West Coast transaction.

Net Interest Income

Comparison of current quarter to prior year period

Net interest income for the third quarter of 2013 was $80.4 million , an increase of 40% from $57.3 million for the same quarter in 2012 . The increase in net interest income was primarily due to the loan interest income and loan discount accretion income related to the acquisition of West Coast.

Incremental accretion income from acquired impaired loans decreased $4.2 million from the prior year period. In addition, the discount accretion on other FDIC acquired loans decreased $347 thousand from the prior year period. These decreases were primarily due to the decreases in the FDIC acquired loan balances resulting from repayments. However, these decreases were more than offset during the current quarter by an increase in discount accretion related to the recently acquired West Coast loan portfolio, which had $10.0 million in discount accretion for the current quarter. For additional information on the Company's accounting policies related to recording interest income on loans, please refer to “Item 8. Financial Statements and Supplementary Data” in our 2012 Annual Report on Form 10-K.

The Company's net interest margin decreased to 5.37% in the third quarter of 2013 , from 5.52% for the same quarter last year, primarily due to the smaller impact of the acquired loan accretion income for the current period. Although the dollar amount of the accretion income was actually higher in the current period, the impact to the net interest margin was greater for the prior year period due to the lower average interest-earning assets balance for the prior year period. The Company's operating net interest margin was 4.41% for the current quarter, an increase of 1 basis point compared to the same period in the prior year.

Table of Contents

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

Net interest income for the nine months ended September 30, 2013 was $213.9 million , an increase of 16% from $184.0 million for the same period in 2012 . The Company's net interest margin and operating net interest margin decreased to 5.21% and 4.33% , respectively, for the first nine months of 2013 , from 5.99% and 4.43% , respectively, for the same prior year period. The increase in net interest income was primarily due to increased loan and securities portfolios resulting from the acquisition of West Coast, which closed on April 1, 2013. The decrease in margin was primarily due to accretion income on the acquired loan portfolios, which were lower in the current period. As shown in the table below, although the Company recorded $19.7 million in discount accretion related to the recently acquired West Coast loan portfolio, the overall incremental accretion income for the nine months ended September 30, 2013 was $4.4 million lower than what was recorded in the prior year period. The modest decrease of 10 basis points in the operating net interest margin was due to the combination of lower rates on loans as well as securities due to the overall decreasing trend in rates.

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

Provision for Loan and Lease Losses

Comparison of current quarter to prior year period

The provision for loan and lease losses for the third quarter of 2013 was $4.3 million for the noncovered loan portfolio and a provision recapture of $947 thousand for the covered loan portfolio compared with a provision of $2.9 million and provision recapture of $4.0 million , respectively, during the third quarter of 2012 . The $947 thousand in provision recapture for losses on covered loans in the current period was primarily due to the increase in expected future cash flows as remeasured during current quarter, compared to the expected future cash flows during the first quarter of 2013, net of the actual cash flows received during the quarter. The $947 thousand in provision recapture is substantially offset by a $758 thousand unfavorable adjustment to the change in FDIC loss-sharing asset.

The $4.3 million provision expense for noncovered loan losses recorded during the current quarter was primarily the result of moving from the initial fair value accounting for the loans acquired in the West Coast Bank acquisition to our standard allowance methodology. The initial fair value accounting resulted in a net loan discount of $88.8 million, $19.7 million of which was recognized as interest income on loans subsequent to the acquisition.

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

The provision for loan and lease losses for the nine months ended September 30, 2013 was $5.3 million for the noncovered loan portfolio and a provision recapture of $1.7 million for the covered loan portfolio compared with provisions of $11.1 million and $23.4 million , respectively, during the same period of 2012 . The $1.7 million in provision recapture for losses on covered loans in the current period was primarily due to the increase in expected future cash flows during the current period, compared to the expected future cash flows at the end of 2012 , net of the actual cash flows received during the current year. The $1.7 million in provision recapture is substantially offset by a $1.3 million unfavorable adjustment to the change in FDIC loss-sharing asset.

Table of Contents

The $5.3 million provision expense for noncovered loan losses was primarily the result of moving from the initial fair value accounting for the loans acquired in the West Coast Bank acquisition to our standard allowance methodology. Net noncovered loan charge-offs for the nine months ended September 30, 2013 were $1.7 million compared to $12.6 million for the same period of 2012 . The amount of provision was calculated in accordance with the Company’s methodology for determining the ALLL, discussed in Note 6 to the Consolidated Financial Statements in "Item 1. Financial Statements (unaudited)" of this report and was based upon improving credit metrics in the noncovered loan portfolio.

Comparison of current quarter to prior year period

Noninterest income was $7.6 million for the third quarter of 2013 , compared to a loss of $911 thousand for the same period in 2012 . The increase was primarily due to increases of $5.7 million in service charges and other fees and $1.5 million in other noninterest income due to the increased customer base from the West Coast acquisition.

The change in FDIC loss-sharing asset is a significant component of noninterest income. Changes in the asset are primarily driven by amortization of the asset and the provision recorded for reimbursable losses on covered loans. For the third quarter of 2013 , there was $9.9 million of amortization of the asset and a $758 thousand decrease in the asset related to the provision recapture recorded for reimbursable losses on covered loans. For the same period in 2012 , there was $9.7 million of amortization of the asset and a $3.2 million decrease in the asset related to the provision recapture recorded for reimbursable losses on covered loans. For additional information on the FDIC loss-sharing asset, please see the "FDIC Loss-sharing Asset" section of Management's Discussion and Analysis and Note 8 to the Consolidated Financial Statements in "Item 1. Financial Statements (unaudited)" of this report.

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

For the nine months ended September 30, 2013 , noninterest income was $16.1 million compared to $20.5 million for the same period in 2012 . The decrease was primarily due to the $35.4 million change in the FDIC loss-sharing asset recorded as a reduction in income during the current year, compared to a $14.8 million reduction in income during the same period of 2012 . The decrease was partially offset by increases of $12.3 million in service charges and other fees and $3.4 million in other noninterest income due to the increased customer base from the West Coast acquisition.

Comparison of current quarter to prior year period

Total noninterest expense for the third quarter of 2013 was $64.7 million , an increase of $23.8 million from a year earlier. The increase from the prior-year period was primarily due to acquisition-related expenses of $7.6 million during the current period as well as additional ongoing noninterest expense resulting from the West Coast acquisition.

In managing our business, we review the efficiency ratio, on a fully taxable-equivalent basis. Our efficiency ratio (noninterest expense, excluding net cost of operation of other real estate, FDIC clawback liability expense and acquisition-related expenses, divided by the sum of net interest income on a tax equivalent basis, excluding incremental accretion income on acquired loan portfolios, premium amortization on acquired securities portfolios, and prepayment charges on FHLB advances, and noninterest income, excluding any gain/loss on sale of investment securities, gain on bank acquisition, and the change in the FDIC indemnification asset) was 66.59% for the third quarter of 2013 compared to 70.36% for the third quarter 2012 . For the nine months ended September 30, 2013 and 2012 , our efficiency ratios were 66.65% and 70.11%, respectively.

Income Taxes

We recorded an income tax provision of $6.7 million for the third quarter of 2013 , compared to a provision of $4.7 million for the same period in 2012 . For the nine months ended September 30, 2013 and 2012 , we recorded an income tax provision of $19.1 million and $12.2 million , respectively, with an effective tax rate of 32% and 27% , respectively. Our effective tax rate increased during the current year primarily due to the acquisition of West Coast. The majority of West Coast’s operations were located in the State of Oregon which has a state income tax. As a result, a larger portion of our income was subject to state income taxes. In addition, certain acquisition-related costs were not tax deductible which also increased our effective tax rate. Our effective tax rate remained lower than the statutory tax rate due to our nontaxable income generated from tax-exempt loans and municipal bonds, investments in bank owned life insurance, and low income housing credits.

Total assets were $7.15 billion as of September 30, 2013 , an increase of $2.24 billion , or 46% from $4.91 billion at December 31, 2012 primarily due to the acquisition of West Coast, which closed on April 1, 2013.

Investment Securities

At September 30, 2013 , the Company held investment securities totaling $1.57 billion compared to $1.00 billion at December 31, 2012 . All of our securities are classified as available for sale and carried at fair value. The increase in the investment securities portfolio from year-end is due to $730.8 million in acquired securities related to the West Coast acquisition, as well as $292.7 million in purchases, partially offset by $407.8 million in maturities and sales, $12.6 million in premium amortization and $35.2 million reduction in fair value of securities in the portfolio. These securities are used by the Company as a component of its balance sheet management strategies. From time-to-time securities may be sold to reposition the portfolio in response to strategies developed by the Company’s asset liability committee. In accordance with our investment strategy, management monitors market conditions with a view to realize gains on its available for sale securities portfolio when prudent.

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

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

At September 30, 2013 , the market value of securities available for sale had a net unrealized loss of $2.9 million compared to a net unrealized gain of $32.3 million at December 31, 2012 . The change in valuation was the result of fluctuations in market interest rates subsequent to purchase. At September 30, 2013 , the Company had $866.8 million of investment securities with gross unrealized losses of $29.7 million ; however, we did not consider these investment securities to be other-than-temporarily impaired.

Credit Risk Management

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 limits to a single borrower. The monitoring process for our loan portfolio includes periodic reviews of individual loans with risk ratings assigned to each loan. We review these loans to assess the ability of the borrower to service all of its interest and principal obligations and, as a result, the risk rating may be adjusted accordingly. In the event that full collection of principal and interest is not reasonably assured, the loan is appropriately downgraded and, if warranted, placed on nonaccrual status even though the loan may be current as to principal and interest payments. Additionally, we review these types of loans for impairment in accordance with the Receivables topic of the FASB ASC. Impaired loans are considered for nonaccrual status and will typically remain as such until all principal and interest payments are brought current and the prospects for future payments in accordance with the loan agreement appear relatively certain.

Loan policies, credit quality criteria, loan portfolio guidelines and other credit approval processes are established under the guidance of our Chief Credit Officer and approved, as appropriate, by the Board of Directors. The Company’s Credit Administration department and loan committee have the responsibility for administering the credit approval process. As another part of its control process, we use an independent internal credit review and examination function to provide assurance that loans and commitments are made and maintained as prescribed by our credit policies. This includes a review of documentation when the loan is initially extended and subsequent monitoring to assess continued performance and proper risk assessment.

Total loans, net	$	4,440,048				$	2,864,803
Loans held for sale	$	840				$	2,563

Total noncovered loans increased $1.67 billion , or 66% , from year-end 2012 . The increase in loans was primarily due to the acquisition of West Coast Bank, which added $1.41 billion at the beginning of the second quarter. In addition to the increase from the acquisition, noncovered loans had organic growth of $241.1 million during the period. The organic growth was centered in commercial business and commercial and multifamily residential real estate loans. The noncovered loan portfolio continues to be diversified, with the intent to mitigate risk by minimizing concentration in any one segment. The $75.3 million in unearned income recorded at September 30, 2013 was comprised of $68.8 million in discount on acquired loans and $6.5 million in deferred loan fees. The $7.8 million in unearned income recorded at December 31, 2012 consisted of $2.2 million in discount on acquired loans and $5.6 million in deferred loan fees.

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

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

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

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

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

Covered Loans: Covered loans are comprised of loans and loan commitments acquired in connection with the 2011 FDIC-assisted acquisitions of First Heritage Bank and Summit Bank, as well as the 2010 FDIC-assisted acquisitions of Columbia River Bank and American Marine Bank. These loans are generically referred to as covered because they are generally subject to one of the loss-sharing agreements between the Company and the FDIC. The loss-sharing agreements relating to the 2010 FDIC-assisted transactions limit the Company’s losses to 20% of the contractual balance outstanding up to a stated threshold amount of $206.0 million for Columbia River Bank and $66.0 million for American Marine Bank. If losses exceed the stated threshold, the Company’s share of the remaining losses decreases to 5%. The loss-sharing agreements relating to the 2011 FDIC-assisted transactions limit the Company's losses to 20% of the contractual balance outstanding. The loss-sharing provisions of the 2011 agreements for commercial and single family residential mortgage loans are in effect for five years and ten years, respectively, from the acquisition dates and the loss recovery provisions for such loans are in effect for eight years and ten years, respectively, from the acquisition dates.

Nonperforming Assets

Nonperforming assets consist of: (i) nonaccrual loans; (ii) other real estate owned; and (iii) other personal property owned.

Nonaccrual noncovered loans : The consolidated financial statements are prepared according to the accrual basis of accounting. This includes the recognition of interest income on the loan portfolio, unless a loan is placed on a nonaccrual basis, which occurs when there are serious doubts about the collectability of principal or interest. Generally our policy is to discontinue the accrual of interest on all loans past due 90 days or more and place them on nonaccrual status. When a noncovered loan is placed on nonaccrual status, any accrued but unpaid interest on that date is removed from interest income.

Covered loans : We consider covered loans to be performing due to the application of the yield accretion method under ASC Topic 310-30. Topic 310-30 allows us to aggregate credit-impaired loans acquired in the same fiscal quarter into one or more pools, provided the loans have common risk characteristics. A pool is then accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. The covered loans acquired are and will continue to be subject to the Company’s internal and external credit review and monitoring. Any credit deterioration experienced subsequent to the initial acquisition will result in a provision for loan losses being charged to earnings. These provisions will be mostly offset by an increase to the FDIC loss-sharing asset and will be recognized in noninterest income.

At September 30, 2013 , nonperforming noncovered assets were $59.6 million , compared to $48.5 million at December 31, 2012 . The increase was due to the acquisition of West Coast Bank, which added $33.6 million of nonperforming assets. Exclusive of the West Coast acquisition, nonperforming noncovered assets decreased $22.5 million during the nine months ended September 30, 2013 as a result of $15.0 million in loan payments, $13.4 million in loans returning to accrual status, $9.8 million in OREO and OPPO sales, $5.6 million in loan and OREO write-downs, partially offset by $21.3 million in new nonaccrual loans. The percent of nonperforming, noncovered assets to period-end noncovered assets at September 30, 2013 was 0.87% compared to 1.08% for December 31, 2012 .

Other Real Estate Owned: During the nine months ended September 30, 2013 , noncovered OREO increased $12.7 million . The following table sets forth activity in noncovered OREO for the nine months ended September 30, 2013 and 2012 :

Allowance for Loan and Lease Losses


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 credit losses 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 periodically based on trends in credit losses, the results of credit reviews and overall economic trends.

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


•	Existing general economic and business conditions affecting our market place


•	Credit quality trends


•	Historical loss experience


•	Seasoning of the loan portfolio


•	Bank regulatory examination results


•	Findings of internal credit examiners


•	Duration of current business cycle


•	Specific loss estimates for problem loans

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

In addition to the ALLL, we maintain an allowance for unfunded commitments and letters of credit. We report this allowance as a liability on our Consolidated Balance Sheet. We determine this amount using estimates of the probability of the ultimate funding and losses related to those credit exposures. This methodology is similar to the methodology we use for determining the adequacy of our ALLL. For additional information on our allowance for unfunded commitments and letters of credit, see Note 5 to the Consolidated Financial Statements presented elsewhere in this report.

At September 30, 2013 , our allowance for loan and lease losses for noncovered loans was $55.8 million , or 1.33% of total noncovered loans (excluding loans held for sale) and 155% of nonperforming, noncovered loans. This compares with an allowance of $52.2 million , or 2.07% of total noncovered loans (excluding loans held for sale), and 140% of nonperforming, noncovered loans at December 31, 2012 . The decrease in the allowance percentage compared to December 31, 2012 resulted from including acquired loans in the ratio, for which only a small allowance was estimated at quarter-end given management's judgment that current net acquisition accounting adjustments still significantly address the estimated credit losses in acquired loans. Excluding acquired loans, the allowance at September 30, 2013 represented 1.73% of noncovered loans. This decrease compared to December 31, 2012 reflects improvements in core asset quality during current year.

FDIC Loss-sharing Asset

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

Subsequent to initial recognition, the FDIC indemnification asset is reviewed quarterly and adjusted for any changes in expected cash flows. These adjustments are measured on the same basis as the related covered loans. Any decrease in expected cash flows from the covered assets due to an increase in expected credit losses will increase the FDIC indemnification asset and any increase in expected future cash flows from the covered assets due to a decrease in expected credit losses will decrease the FDIC indemnification asset. Increases and decreases to the FDIC loss-sharing asset are recorded as adjustments to noninterest income.

At September 30, 2013 , the FDIC loss-sharing asset was $53.6 million which was comprised of a $48.4 million FDIC indemnification asset and a $5.2 million FDIC receivable. The FDIC receivable represents the amounts due from the FDIC for claims related to covered losses the Company has incurred net of amounts due to the FDIC relating to shared recoveries.

The following table summarizes the activity related to the FDIC loss-sharing asset for the three and nine months ended September 30, 2013 and 2012 :

Liquidity and Sources of Funds

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

Deposit Activities

Our deposit products include a wide variety of transaction accounts, savings accounts and time deposit accounts. Core deposits (demand deposit, savings, money market accounts and certificates of deposit less than $100,000) increased $1.86 billion since year-end 2012 due to the acquisition of West Coast.

Table of Contents

We have established a branch system to serve our consumer and business depositors. In addition, management’s strategy for funding asset growth is to make use of brokered and other wholesale deposits on an as-needed basis. The Company participates in the Certificate of Deposit Account Registry Service (CDARS ^® ) program. CDARS ^® is a network that allows participating banks to offer extended FDIC deposit insurance coverage on time deposits. The Company also participates in a similar program to offer extended FDIC deposit insurance coverage on money market accounts. These extended deposit insurance programs are generally available only to existing customers and are not used as a means of generating additional liquidity. At September 30, 2013 CDARS ^® deposits and brokered money market deposits were $76.5 million , or 1% of total deposits, compared to $26.7 million at year-end 2012 . The brokered deposits have varied maturities.

Borrowings

We rely on FHLB advances and FRB borrowings as another source of both short and long-term funding. FHLB advances and FRB borrowings are secured by bonds within our investment portfolio, residential, commercial and commercial real estate loans. At September 30, 2013 we had FHLB advances of $34.0 million, before acquisition date fair value adjustments compared to $6.0 million at December 31, 2012 . The increase in FHLB borrowings related to the acquisition of West Coast.

We also utilize wholesale repurchase agreements as a supplement to our funding sources. Our wholesale repurchase agreements are secured by mortgage-backed securities. At September 30, 2013 and December 31, 2012 we had repurchase agreements of $25.0 million, which mature in 2018. Management anticipates we will continue to rely on FHLB advances, FRB borrowings, and wholesale repurchase agreements in the future and we will use those funds primarily to make loans and purchase securities.

Contractual Obligations & Commitments

We are party to many contractual financial obligations, including repayment of borrowings, operating and equipment lease payments, commitments to extend credit and investments in affordable housing partnerships. At September 30, 2013 , we had commitments to extend credit of $1.42 billion compared to $908.5 million at December 31, 2012 .

Capital Resources

Shareholders’ equity at September 30, 2013 was $1.05 billion , an increase from $764.0 million at December 31, 2012 , primarily due to shares issued in conjunction with the acquisition of West Coast. Shareholders’ equity was 15% of total period-end assets at September 30, 2013 compared to 16% at December 31, 2012 .

Capital Ratios : Banking regulations require bank holding companies to maintain a minimum “leverage” ratio of core capital to adjusted quarterly average total assets of at least 3%. In addition, banking regulators have adopted risk-based capital guidelines, under which risk percentages are assigned to various categories of assets and off-balance sheet items to calculate a risk-adjusted capital ratio. Tier I capital generally consists of preferred stock, common shareholders’ equity, and trust preferred obligations, less goodwill and certain identifiable intangible assets, while Tier II capital includes the allowance for loan losses and subordinated debt, both subject to certain limitations. Regulatory minimum risk-based capital guidelines require Tier I capital of 4% of risk-adjusted assets and total capital (combined Tier I and Tier II) of 8% to be considered “adequately capitalized”.

Federal Deposit Insurance Corporation regulations set forth the qualifications necessary for a bank to be classified as “well capitalized”, primarily for assignment of FDIC insurance premium rates. To qualify as “well capitalized,” banks must have a Tier I risk-adjusted capital ratio of at least 6%, a total risk-adjusted capital ratio of at least 10%, and a leverage ratio of at least 5%. Failure to qualify as “well capitalized” can negatively impact a bank’s ability to expand and to engage in certain activities.

The decrease in the Company's capital ratios from December 31, 2012 was primarily due to our deployment of capital for the acquisition of West Coast. The Company and its banking subsidiary qualify as “well-capitalized” at September 30, 2013 and December 31, 2012 .

Stock Repurchase Program

In 2011, the Board of Directors approved a stock repurchase program authorizing the Company to repurchase up to 2 million shares of its outstanding shares of common stock. The Company intends to 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 the first nine months of 2013 .

Non-GAAP Financial Measures

The Company considers operating net interest margin to be an important measurement as it more closely reflects the ongoing operating performance of the Company. Despite the importance of the operating net interest margin to the Company, there is no standardized definition for it and, as a result, the Company's calculations may not be comparable with other organizations. Also, there may be limits in the usefulness of this measure to investors. As a result, the Company encourages readers to consider its consolidated financial statements in their entirety and not to rely on any single financial measure.

The following table reconciles the Company's calculation of the operating net interest margin to the net interest margin.

Item 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

A number of measures are used to monitor and manage interest rate risk, including income simulations and interest sensitivity (gap) analysis. An income simulation model is the primary tool used to assess the direction and magnitude of changes in net interest income resulting from changes in interest rates. Basic assumptions in the model include prepayment speeds on mortgage-related assets, cash flows and maturities of other investment securities, loan and deposit volumes and pricing. These assumptions are inherently subjective and, as a result, the model cannot precisely estimate net interest income or precisely predict the impact of higher or lower interest rates on net interest income. Actual results will differ from simulated results due to timing, magnitude and frequency of interest rate changes and changes in market conditions and management strategies, among other factors. At September 30, 2013 , based on the measures used to monitor and manage interest rate risk, there has not been a material change in the Company’s interest rate risk since December 31, 2012 . For additional information, refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s 2012 Annual Report on Form 10-K.


Item 4.	CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

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

Changes in Internal Controls Over Financial Reporting

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

PART II - OTHER INFORMATION


Item 1.	LEGAL PROCEEDINGS

On June 24, 2009, West Coast Trust, which as a result of our recent acquisition of West Coast Bancorp (“West Coast”) is now a subsidiary of the Company, was served with an Objection to Personal Representative's Petition and Petition for Surcharge of Personal Representative in Linn County Circuit Court. The petition was filed by the beneficiaries of the estate of Archie Q. Adams, for which West Coast Trust acts as the personal representative. The petitioners allege a breach of fiduciary duty with respect to West Coast Trust's prior sale of real property owned by the Adams estate and sought relief in the form of a surcharge to West Coast Trust of $215.6 million, the amount of the alleged loss to the estate. West Coast Trust filed a motion to dismiss on July 2, 2009, which was granted in a letter ruling dated September 15, 2009. Petitioners appealed and briefs have been filed. Appeals Court oral arguments were heard in November, 2012, and the Company has not yet received the Appeals Court decision. The Company believes the appeal and underlying petition are without merit.

On October 3, 2012, a class action complaint was filed in the Circuit Court of the State of Oregon for the County of Multnomah against West Coast, its directors, and the Company challenging the merger: Gary M. Klein v. West Coast Bancorp, et al., Case No. 1210-12431. The complaint names as defendants West Coast, all of the former members of West Coast's board of directors, and the Company. The complaint alleges that the West Coast directors breached their fiduciary duties to West Coast and West Coast shareholders by agreeing to the merger at an unfair price. The complaint also alleges that the merger was being driven by an unfair process, that the directors approved provisions in the merger agreement that constitute preclusive deal protection devices, that certain large shareholders of West Coast were using the merger as an opportunity to sell their illiquid holdings in West Coast, and that West Coast directors and officers would obtain personal benefits from the merger not shared equally by other West Coast shareholders. The complaint further alleges that West Coast and the Company aided and abetted the directors' alleged breaches of their fiduciary duties. Thereafter, a second lawsuit challenging the merger was filed in the Circuit Court of the State of Oregon for Clackamas County: Leoni v. West Coast Bancorp et al., Case No. CV12100728. The two lawsuits have been consolidated for all purposes in the Circuit Court of the State of Oregon for Multnomah County.

While the Company believes that the claims in both complaints were without merit, the Company agreed, in order to avoid the expense and burden of continued litigation and pursuant to the terms of the proposed settlement, to make certain supplemental disclosures in the joint proxy statement/prospectus related to the merger. Accordingly, prior to the closing of the merger on April 1, 2013, West Coast and the other defendants in the two actions entered into a memorandum of understanding to settle both actions. Pursuant to the memorandum of understanding, Plaintiffs’ counsel has conducted certain confirmatory discovery, and the Company has now approved the form of a stipulation of settlement, which is in the process of being finalized and submitted for court approval. The stipulation of settlement is subject to customary conditions, including court approval following notice to West Coast's stockholders. In the event that all of the parties enter into a stipulation of settlement, a hearing will be scheduled at which the Circuit Court of the State of Oregon for Multnomah County will consider the fairness, reasonableness, and adequacy of the settlement. If the settlement is finally approved by the court, it will resolve and release all claims in all actions that were or could have been brought challenging any aspect of the merger, the merger agreement, and any disclosure made in connection therewith, pursuant to terms that will be disclosed to stockholders before final approval of the settlement. There can be no assurance that all of the parties will ultimately enter into the stipulation of settlement or that the Circuit Court of the State of Oregon for Multnomah County will approve the settlement even if all of the parties were to enter into such stipulation. In such event, the proposed settlement as contemplated by the memorandum of understanding may be terminated.

Item 1A. RISK FACTORS

Refer to Item 1A of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of risk factors relating to the Company’s business. The Company believes that there has been no material change in its risk factors as previously disclosed in the Company’s Form 10-K, except for the following additional risk factor.

Significant legal actions could subject us to substantial uninsured liabilities and reputational harm and have a material adverse effect on our business and results of operations.

We are from time to time subject to claims and proceedings related to our operations, which now include certain legal proceedings we assumed in connection with our recent acquisition of West Coast. Such claims and legal actions could involve large monetary claims, including civil money penalties or fines imposed by government authorities, and significant defense costs. In that regard, we are currently involved in active assumed legal proceedings. If one or more of those legal proceedings is decided in a manner that is adverse to us it could have a material adverse effect on our business and/or results of operation.

To protect against financial exposure from such claims, we maintain insurance coverage in amounts and with deductibles that we believe are appropriate for our operations. However, our insurance coverage does not cover any civil money penalties or fines imposed by government authorities and may not cover all other claims that might be brought against us or continue to be available to us at a reasonable cost. As a result, we may be exposed to substantial uninsured liabilities, which could adversely affect our business, prospects, results of operations and financial condition. Substantial uninsured legal action against us could have material adverse financial effects or cause significant reputational harm to us, which in turn could harm our business prospects.
