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”). 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 three months ended March 31, 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 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 current period with no impact to the Company's financial condition or results of operations. See Note 11 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 $2.5 million of indemnification asset amortization was recorded during the period, resulting in a reduction of $1.6 million in net income and $0.04 in earnings per share.

At March 31, 2013 , there were 18 U.S. government agency and government-sponsored enterprise mortgage-backed securities & collateralized mortgage obligations securities in an unrealized loss position, of which one was in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where 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 March 31, 2013 .

At March 31, 2013 , there were 15 state and municipal government securities in an unrealized loss position, of which one was 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 March 31, 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 March 31, 2013 .

At March 31, 2013 , there were 11 U.S. government agency and government-sponsored enterprise securities in an unrealized loss position, of which none 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 March 31, 2013 .

At March 31, 2013 , there were two U.S. government securities in an unrealized loss position, neither of which was in a continuous loss position for 12 months or more.

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 $1.8 million and $236 thousand of additional funds on loans classified as TDR as of March 31, 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 three months ended March 31, 2013 .

5.	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.

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 three months ended March 31, 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.

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

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.

The monitoring process for the loan portfolio includes periodic reviews of individual loans with risk ratings assigned to each loan. Based on the analysis, loans are given a risk rating of 1-10 based on the following criteria:


•	ratings of 1-3 indicate minimal to low credit risk,


•	ratings of 4-5 indicate an average credit risk with adequate repayment capacity when prolonged periods of adversity do not exist,


•	rating of 6 indicate higher than average risk requiring greater than routine attention by bank personnel due to conditions affecting the borrower, the borrower's industry or economic environment,


•	rating of 7 indicate 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,


•	rating of 8 indicates a loss is possible if loan weaknesses are not corrected,


•	rating of 9 indicates loss is highly probable; however, the amount of loss has not yet been determined,


•	and a rating of 10 indicates the loan is uncollectable, and when identified is charged-off.

Loans with a risk rating of 1-6 are considered Pass loans and loans with risk ratings of 7, 8, 9 and 10 are considered Special Mention, Substandard, Doubtful and Loss, respectively. 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. 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.

7. 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. As of March 31, 2013 , the net present value of the Bank’s estimated clawback liability is $3.8 million , which is included in other liabilities on the consolidated balance sheets.

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

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

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

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

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

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

The following table shows the changes in accretable yield for acquired loans for the three months ended March 31, 2013 and 2012 :

Balance at end of period	$	158,786		$	239,677

During the three months ended March 31, 2013 , the Company recorded a provision expense for losses on covered loans of $980 thousand . Of this amount, $1.3 million was impairment expense calculated in accordance with ASC 310-30 and $300 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 $980 thousand of provision expense for covered loans was partially offset through noninterest income by a $784 thousand increase in the FDIC loss-sharing asset.

The changes in the ALLL for covered loans for the three months ended March 31, 2013 and 2012 are summarized as follows:

Table of Contents

The following table sets forth activity in covered OREO at carrying value for the three months ended March 31, 2013 and 2012 :



	Three Months Ended March 31,
	2013			2012
	(in thousands)
Covered OREO:

Net gain on sale of OREO	2,598			3,366
Total covered OREO at end of period	$	13,811		$	24,430

The covered OREO is covered by 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 March 31, 2013 , the FDIC loss-sharing asset is comprised of a $75.5 million FDIC indemnification asset and a $7.6 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 months ended March 31, 2013 and 2012 :

8.	Goodwill and Intangible Assets

In accordance with the Intangibles – Goodwill and Other topic of the FASB ASC, goodwill is not amortized but is reviewed for potential impairment at the reporting unit level. Management analyzes its goodwill for impairment on an annual basis on July 31 and between annual tests in certain circumstances such as material adverse changes in legal, business, regulatory and economic factors. An impairment loss is recorded to the extent that the carrying amount of goodwill exceeds its implied fair value.

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

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

9.	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 March 31, 2013 and December 31, 2012 was $158.9 million and $177.0 million , respectively. There was no impact to the statement of operations for the three month periods ending March 31, 2013 and 2012 .

12.	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.

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 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 cost 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 March 31, 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 March 31, 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 March 31, 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.

13.	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.

The following table sets forth the computation of basic and diluted earnings per share for the three months ended March 31, 2013 and 2012 :

14. Subsequent Events

Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Nonrecognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date.

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 growth strategy. The operating results of the Company for the three months ended March 31, 2013 do not include the operating results produced by West Coast as the acquisition did not close until April 1, 2013. It is not practical to present financial information related to the acquisition at this time because the fair value measurement of assets acquired and liabilities assumed has not been finalized.

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.

Earnings Summary

The Company reported net income for the first quarter of $12.2 million or $0.31 per diluted common share, compared to $8.9 million or $0.22 per diluted common share for the first quarter of 2012 .

The increase in net income from the first quarter of 2012 was attributable to lower noninterest expense and provision for loan losses on noncovered loans, partially offset by a reduction in the pretax earnings impact of the acquired loan portfolio.

Revenue (net interest income plus noninterest income) for the three months ended March 31, 2013 was $55.1 million , 28% less than the same period in 2012 . The decrease in revenue was a result of lower incremental accretion income on acquired loans. 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 first quarter of 2013 was a recapture of $1.0 million for the noncovered loan portfolio and a provision of $980 thousand for the covered loan portfolio compared to provisions of $4.5 million for the noncovered loan portfolio and $15.7 million for the covered loan portfolio during the first quarter of 2012 . The $1.0 million provision recapture for the noncovered loan portfolio for the three months ended March 31, 2013 was due to improving credit metrics within the noncovered loan portfolio as well as a $2.0 million recovery experienced during the current quarter related to a single borrowing relationship. The Company believes that, at 1.95% of net noncovered loans, the allowance for loan and lease losses remains adequate at March 31, 2013 . The allowance to net noncovered loans was 2.07% at year-end 2012 . The $980 thousand in provision for losses on covered loans for the three months ended March 31, 2013 was primarily due to decreased expected future cash flows as remeasured during the current quarter when compared to the prior quarter's remeasurement. The $980 thousand in provision is partially off-set by a $784 thousand favorable adjustment to the change in FDIC loss-sharing asset.

Total noninterest expense for the quarter ended March 31, 2013 was $38.0 million , a 14% decrease from the first quarter of 2012 . The decrease from the prior-year period was primarily due to substantial write-downs of OREO and OPPO during the first quarter of the prior year.

Table of Contents

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



	Three Months Ended March 31,
	2013			2012
	( in thousands)
Incremental accretion income on acquired loans	$	9,445		$	22,421
Provision for losses on covered loans	(980		)	(15,685		)
Change in FDIC-loss sharing asset	(10,483		)	(1,668		)
FDIC clawback liability expense	(231		)	26
Pre-tax earnings impact of acquisition accounting	$	(2,249	)	$	5,094

Net Interest Income

Net interest income for the first quarter of 2013 was $53.5 million , a decrease of 20% from $67.1 million for the same quarter in 2012 . The Company's net interest margin decreased to 5.06% in the first quarter of 2013 , from 6.67% for the same quarter last year. The decreases in net interest income and margin were primarily due to accretion income on the acquired loan portfolios, which were significantly lower in the current period. In addition to the impact of accretion income, net interest income also decreased due to the combination of lower rates on loans as well as securities due to the overall decreasing trend in rates.

The incremental accretion income represents the amount of income recorded on the acquired loans above the contractual rate stated in the individual loan notes. The incremental accretion income had a positive impact of approximately 87 bps on the first quarter's net interest margin. For the same period last year, the incremental accretion income had a positive impact of approximately 218 bps on the net interest margin.

Incremental accretion income from acquired impaired loans decreased $10.9 million from the prior year period. In addition, the discount accretion on other acquired loans decreased $2.0 million from the prior year period. These decreases were primarily due to the moderating trend for incremental accretion income due to decreases in the acquired loan balances resulting from repayments. 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 following table shows the impact to interest income and the related impact to the net interest margin resulting from accretion of income on certain acquired loan portfolios for the periods presented:

Nonaccrual loans have been included in the tables as loans carrying a zero yield. Amortized net deferred loan fees were included in the interest income calculations. The amortization of net deferred loan fees was $661 thousand and $312 thousand for the three months ended March 31, 2013 and 2012 , respectively. The amortization of net unearned discounts on other acquired loans was $1.1 million and $3.1 million for the three months ended March 31, 2013 and 2012 , respectively.

(2)

Tax-exempt income is calculated on a tax equivalent basis, based on a marginal tax rate of 35%. The tax equivalent yield adjustment to interest earned on noncovered loans was $127 thousand and $193 thousand for the three months ended March 31, 2013 and 2012 , respectively. The tax equivalent yield adjustment to interest earned on tax exempt securities was $1.3 million and $1.4 million for the three months ended March 31, 2013 and 2012 , respectively.


(3)	Reclassified to conform to the current period's presentation.

Table of Contents

The following tables set forth the total dollar amount of change in interest income and interest expense. The changes have been segregated for each major category of interest-earning assets and interest-bearing liabilities into amounts attributable to changes in volume, changes in rates and changes in rates multiplied by volume. Changes attributable to the combined effect of volume and interest rates have been allocated proportionately to the changes due to volume and the changes due to interest rates:

Provision for Loan and Lease Losses

The provision for loan and lease losses for the first quarter of 2013 was a recapture of $1.0 million for the noncovered loan portfolio and a provision of $980 thousand for the covered loan portfolio compared with provisions of $4.5 million and $15.7 million , respectively, during the first quarter of 2012 . The $980 thousand in provision for losses on covered loans in the current period was primarily due to the decrease in expected future cash flows from covered loans as remeasured during current quarter, compared to the expected future cash flows as remeasured during the fourth quarter of 2012, net of the actual cash flows received during the quarter. The $980 thousand in provision expense is substantially offset by a $784 thousand favorable adjustment to the change in FDIC loss-sharing asset.

The $1.0 million provision recapture for noncovered loan losses was due to improving credit metrics within the noncovered loan portfolio as well as a $2.0 million recovery experienced during the current quarter related to a single borrowing relationship. Net noncovered loan charge-offs for the current quarter were $125 thousand compared to $5.3 million for the first quarter of 2012 . The amount of provision was calculated in accordance with the Company’s methodology for determining the ALLL, discussed in Note 5 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.

Total noninterest income	$	1,658		$	9,574		$	(7,916	)	(83	)%

Noninterest income was $1.7 million for the first quarter of 2013 , compared to $9.6 million for the same period in 2012 . The decrease was primarily due to the $10.5 million change in the FDIC loss-sharing asset recorded as a reduction in income during the current quarter, compared to a $1.7 million reduction in income during the same period in 2012 . This decrease was partially offset by an increase of $417 thousand in service charges and other fees as well as an increase in other noninterest income of $354 thousand, which was due to an increase in Small Business Administration premiums in the current quarter.

Changes in the FDIC loss-sharing asset are primarily driven by amortization of the FDIC loss-sharing asset and the provision recorded for reimbursable losses on FDIC covered loans. For the first quarter of 2013 , the $9.8 million of amortization of the FDIC loss-sharing asset was partially offset by a $784 thousand increase in the FDIC loss-sharing asset related to the provision recorded for reimbursable losses on FDIC covered loans. For the same period in 2012 , the $13.9 million of amortization of the FDIC loss-sharing asset was partially offset by a $12.5 million increase in the FDIC loss-sharing asset related to the provision expense recorded for reimbursable losses on FDIC 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 7 to the Consolidated Financial Statements in "Item 1. Financial Statements (unaudited)" of this report.

Total noninterest expense	$	38,049		$	44,352		$	(6,303	)	(14	)%

Total noninterest expense for the first quarter of 2013 was $38.0 million , a decrease of $6.3 million , or 14% from $44.4 million a year earlier. The decrease from the prior-year period was due to a decrease of $2.7 million in other noninterest expense as well as a decrease of $3.4 million in net cost (benefit) of operation of other real estate. The decrease in other noninterest expense was primarily due to the Company recording $2.2 million in OPPO write-downs during the prior year period. The decrease in net cost (benefit) of operation of OREO was due to substantial write-downs recorded in the prior year period. These decreases were partially offset by a $441 thousand increase in legal and professional expenses, which includes $508 thousand during the current quarter related to the acquisition of West Coast Bancorp. Total merger related expense for the current quarter was $723 thousand.

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 merger related expenses, divided by the sum of net interest income and noninterest income on a tax equivalent basis, excluding any gain/loss on sale of investment securities, gain on bank acquisition, incremental accretion income on the acquired loan portfolio and the change in the FDIC indemnification asset) was 68.68% for the first quarter of 2013 compared to 71.48% for the first quarter 2012 .

Income Taxes

We recorded an income tax provision of $4.9 million for the first quarter of 2013 , compared to a provision of $3.2 million for the same period in 2012 . The effective tax rate was 29% for the first quarter of 2013 compared to 26% for the first quarter of 2012 . Our effective tax rate remains 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. For additional information, please refer to the Company's annual report on Form 10-K for the year ended December 31, 2012 .

FINANCIAL CONDITION

Total assets were $4.91 billion as of March 31, 2013 , relatively unchanged from December 31, 2012 .

Investment Securities

At March 31, 2013 , the Company held investment securities totaling $1.01 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 $84.7 million in purchases, partially offset by $67.4 million in maturities and sales of securities in the portfolio. These securities are used by t he 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.

At March 31, 2013 , the market value of securities available for sale had an unrealized gain of $28.1 million compared to an unrealized gain of $32.3 million at December 31, 2012 . The decrease in the unrealized gain was the result of the fluctuations in interest rates. The Company does carry $352.0 million of investment securities with unrealized losses of $7.9 million ; however, we do not consider these investment securities to be other-than-temporarily impaired. In the future, if the impairment is judged to be other-than-temporary, to the extent that the loss is determined to be credit-related, the cost basis of the individual impaired securities will be written down to fair value; the amount of the write-down could be included in earnings as a realized loss. The remaining non-credit-related impairment would be recorded to other comprehensive income.

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.

Loan Portfolio Analysis

We are a full service commercial bank, which originates a wide variety of loans, and focuses its lending efforts on originating commercial business and commercial real estate loans.

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

Total loans, net	$	2,933,306				$	2,864,803
Loans held for sale	$	888				$	2,563

Total noncovered loans increased $95.5 million , or 4% , from year-end 2012 . Growth was centered in the commercial business loan segment which increased $49.6 million. Growth in this segment was led by the healthcare industry. There was also strong broad based growth in the commercial and multifamily residential real estate loans. The growth in business and commercial real estate loans was partially offset by small reduction in consumer loans. The noncovered loan portfolio continues to be diversified, with the intent to mitigate risk by minimizing concentration in any one segment.

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.

Table of Contents

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.

The following table set forth, at the dates indicated, information with respect to our noncovered nonaccrual loans and total noncovered nonperforming assets:

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

Table of Contents

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 March 31, 2013 , our allowance for loan and lease losses for noncovered loans was $51.1 million , or 1.95% 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 following table provides an analysis of the Company’s allowance for loan and lease losses for noncovered loans at the dates and the periods indicated:

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 March 31, 2013 , the FDIC loss-sharing asset was $83.1 million which was comprised of a $75.5 million FDIC indemnification asset and a $7.6 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 months ended March 31, 2013 and 2012 :



	Three Months Ended March 31,

For additional information on the FDIC loss-sharing asset, please see Note 7 to the Consolidated Financial Statements presented elsewhere in this report.

Liquidity and Sources of Funds

Our primary sources of funds are customer deposits. Additionally, we utilize advances from the FHLB of 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) were relatively unchanged since year-end 2012 while certificates of deposit greater than $100,000 decreased $8.4 million , or approximately 4% , to $204.5 million from year-end 2012 .

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 also 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 certificates of deposit. Unlike traditional brokered deposits, the Company generally makes CDARS ^® available only to existing customers who desire additional deposit insurance coverage rather than as a means of generating additional liquidity. At March 31, 2013 CDARS ^® deposits and other brokered deposits were $45.4 million , or 1% of total deposits, compared to $26.7 million at year-end 2012 . The brokered deposits have varied maturities.

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

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 March 31, 2013 and December 31, 2012 , we had FHLB advances of $6.0 million, bef ore acquisition date fair value adjustments.

We also utilize wholesale repurchase agreements as a supplement to our funding sources. Our wholesale repurchase agreements are secured by mortgage-backed securities. At March 31, 2013 and December 31, 2012 we had repurchase agreem ents of $25.0 million, wh ich 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 an d investments in affordable housing partnerships. At March 31, 2013 , we had commitments to extend credit of $924.4 million compared to $908.5 million at December 31, 2012 .

Capital Resources

Shareholders’ equity at March 31, 2013 was $769.7 million , a slig ht increase from $764.0 million at December 31, 2012 . Shareholders’ equity was 16% of total period-end assets at both March 31, 2013 and 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 Company and its subsidiary qualify as “well-capitalized” at March 31, 2013 and December 31, 2012 .



	Company				Columbia Bank				Requirements
	March 31, 2013		December 31, 2012		March 31, 2013		December 31, 2012		Adequately capitalized		Well- Capitalized
Total risk-based capital ratio	20.29	%	20.62	%	17.64	%	17.87	%	8.00	%	10.00	%
Tier 1 risk-based capital ratio	19.02	%	19.35	%	16.38	%	16.60	%	4.00	%	6.00	%
Leverage ratio	13.19	%	12.78	%	11.44	%	11.07	%	4.00	%	5.00	%

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 three months of 2013 .

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 March 31, 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 current 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 proposed merger at an unfair price. The complaint also alleges that the proposed merger is 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 are using the merger as an opportunity to sell their illiquid holdings in West Coast, and that West Coast directors and officers will 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 parties have previously stipulated to the consolidation of the two lawsuits for all purposes in the Circuit Court of the State of Oregon for Multnomah County, and the Company and West Coast have consented to the filing of an unopposed motion to consolidate both lawsuits and extending the time for defendants to file a responsive pleading until July 5, 2013.

While West Coast believes that the claims in both complaints are without merit, West Coast 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. Subject to completion of certain confirmatory discovery by plaintiffs' counsel, the memorandum of understanding contemplates that the parties will enter into a stipulation of settlement. The stipulation of settlement will be subject to customary conditions, including court approval following notice to West Coast's stoc kholders. In the event that 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 o f 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 the parties will ultimately enter into a stipulation of settlement or that the Circuit Court of the State of Oregon for Multnomah County will approve the settlement even if 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.
