MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

 

 

Columbia Banking System, Inc. which we refer to as “Columbia,” and West Coast Bancorp, which we refer to as “West Coast,” have entered into a definitive merger agreement that provides for the combination of the two companies. Under the merger agreement, a wholly owned subsidiary of Columbia will merge with and into West Coast, with West Coast remaining as the surviving entity and a wholly owned subsidiary of Columbia (which transaction we refer to as the “merger”). Such surviving entity will, as soon as reasonably practicable following the merger and as part of a single integrated transaction, merge with and into Columbia (we refer to the two mergers together as the “mergers”). Before we complete the merger, the shareholders of West Coast must approve the merger agreement pursuant to Oregon law. West Coast shareholders will vote to approve the merger agreement at a special meeting of shareholders to be held on March 18, 2013. Columbia shareholders must approve the issuance of the shares of Columbia common stock in connection with the merger pursuant to the requirements of the Nasdaq Stock Exchange. Columbia shareholders will vote to approve the issuance of the shares of Columbia common stock in connection with the merger at a special meeting of shareholders to be held on March 18, 2013.

Under the terms of the merger agreement, the aggregate merger consideration payable by Columbia will consist of 12,809,525 shares of Columbia common stock and $264,468,650 in cash (subject to increase under certain circumstances). West Coast shareholders may elect to receive either cash, stock, or a unit consisting of a mix of cash and stock, in an amount equal to such holder’s pro rata share (subject to certain adjustments) of the total merger consideration. However, because the total amount of cash and stock to be issued by Columbia is fixed, a West Coast shareholder may receive a combination of cash and stock that differs from such holder’s election if too many West Coast shareholders elect one form of consideration over the other. We expect the mergers, taken together, to be a tax-free transaction for West Coast shareholders, to the extent they receive Columbia common stock for their shares of West Coast common stock. Based on the 12,809,525 fixed shares issued by Columbia to West Coast shareholders, after completion of the merger, West Coast shareholders would own approximately 24% of Columbia’s common stock (including shares of Columbia common stock issuable upon conversion of Series B Preferred Stock and the exercise of Class C Warrants, and ignoring any shares of Columbia common stock they may already own).

The value of the consideration to be received by West Coast shareholders in the merger will vary with the trading price of Columbia common stock between now and the completion of the merger. The per share consideration is determined by the quotient obtained by dividing (1) the sum of: (A) the product of: (i) the Purchaser Average Closing Price (as defined in the Merger Agreement) and (ii) the total Columbia shares to be issued; and (B) the total cash Columbia will pay; and (C) $24 million plus proceeds from in-the-money option exercises; by (2) the sum of common share equivalents from common shares, preferred stock, warrants and in-the-money options. The table below shows the approximate hypothetical value of the merger consideration per share if it had been calculated based on the closing price for Columbia common stock on the Nasdaq Global Select Market on each of September 25, 2012, the trading day immediately prior to the announcement of the merger, and January 31, 2013, the last practicable trading day prior to the date of this document.

 

Date		Columbia closing price		Per share consideration
September 25, 2012		$18.85		$23.08
January 31, 2013		$20.20		$23.83

The market prices of both Columbia common stock and West Coast common stock will fluctuate before the merger. You should obtain current stock price quotations for Columbia common stock and West Coast common stock. Columbia common stock is traded on the Nasdaq Global Select Market under the symbol “COLB,” and West Coast common stock is traded on the Nasdaq Global Select Market under the symbol “WCBO.”

The West Coast board of directors has unanimously determined that the combination of West Coast and Columbia is in the best interests of West Coast shareholders based upon its analysis, investigation and deliberation, and the West Coast board of directors unanimously recommends that the West Coast shareholders vote “FOR” the approval of the merger agreement and “FOR” the approval of the other proposals described in this joint proxy statement/prospectus.

The Columbia board of directors has also unanimously determined that the combination of Columbia and West Coast is in the best interests of Columbia shareholders based upon its analysis, investigation and deliberation, and the Columbia board of directors unanimously recommends that the Columbia shareholders vote “FOR” the issuance of shares of Columbia common stock in connection with the merger and “FOR” the approval of the other proposals described in this joint proxy statement/prospectus.

You should read this entire joint proxy statement/prospectus, including the appendices and the documents incorporated by reference into the document, carefully because it contains important information about the merger and the related transactions. In particular, you should read carefully the information under the section entitled “Risk Factors” beginning on page 18.

The shares of Columbia common stock to be issued to West Coast shareholders in the merger are not deposits or savings accounts or other obligations of any bank or savings association, and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved the merger described in this joint proxy statement/prospectus or the Columbia common stock to be issued in the merger, or passed upon the adequacy or accuracy of this joint proxy statement/prospectus. Any representation to the contrary is a criminal offense.

This joint proxy statement/prospectus is dated February 1, 2013 and is first being mailed to the shareholders of West Coast and the shareholders of Columbia on or about February 7, 2013.

RISK FACTORS

In addition to the other information contained in or incorporated by reference into this document, including Columbia’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011 and West Coast’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011, and the matters addressed under the caption “Cautionary Note Regarding Forward-Looking Statements,” West Coast shareholders should consider the matters described below carefully in determining whether to vote to approve the merger agreement and the transactions contemplated by the merger agreement, and Columbia shareholders should consider the matters described below carefully in determining whether to vote to approve the issuance of shares of Columbia common stock in the merger.

Risk Factors Relating to the Merger

Because the market price of Columbia common stock may fluctuate, you cannot be sure of the value of the merger consideration that you will receive.

Upon completion of the merger, each share of West Coast common stock (other than certain shares owned by West Coast, Columbia or their wholly-owned subsidiaries) will be converted into the right to receive merger consideration consisting of shares of Columbia common stock or cash, or a unit consisting of a mix of Columbia common stock and cash, pursuant to the terms of the merger agreement. The value of the merger consideration to be received by West Coast shareholders will be based on the volume weighted average price of Columbia common stock during the twenty trading day period beginning on the twenty fifth day before the effective time of the merger. This average price may vary from the closing price of Columbia common stock on the date we announced the merger, on the date that this document was mailed to Columbia shareholders and West Coast shareholders, and on the date of the meetings of the Columbia and West Coast shareholders. Any change in the market price of Columbia common stock prior to completion of the merger will affect the value of the merger consideration that West Coast shareholders will receive upon completion of the merger. Accordingly, at the time of the West Coast special meeting and prior to the election deadline, West Coast shareholders will not know or be able to calculate the amount of the cash consideration they would receive or the exchange ratio used to determine the number of any shares of Columbia common stock they would receive upon completion of the merger. Stock price changes may result from a variety of factors, including general market and economic conditions, changes in our respective businesses, operations and prospects, and regulatory considerations, among other things. Many of these factors are beyond the control of Columbia and West Coast. West Coast shareholders should obtain current market quotations for shares of Columbia common stock before voting their shares at the West Coast special meeting.

West Coast shareholders may receive a form of consideration different from what they elect.

Although each West Coast shareholder may elect to receive all cash or all Columbia common stock in the merger, or a unit consisting of a mix of cash and stock, the pools of cash and Columbia common stock to be paid in the merger are fixed. As a result, if either the aggregate cash or stock elections exceed the maximum available, and you choose the consideration election that exceeds the maximum available, some or all of your consideration may be in a form that you did not choose.

We may fail to realize all of the anticipated benefits of the merger.

The success of the merger will depend, in part, on our ability to successfully combine the Columbia and West Coast organizations. If we are not able to achieve this objective, the anticipated benefits of the merger may not be realized fully or at all or may take longer than expected to be realized.

Columbia and West Coast have operated and, until the completion of the merger, will continue to operate, independently. It is possible that the integration process or other factors could result in the loss or departure of key employees, the disruption of the ongoing business of West Coast or inconsistencies in standards, controls,

Table of Contents

procedures and policies. It is also possible that clients, customers, depositors and counterparties of West Coast could choose to discontinue their relationships with the combined company post-merger because they prefer doing business with an independent company or for any other reason, which would adversely affect the future performance of the combined company. These transition matters could have an adverse effect on each of Columbia and West Coast during the pre-merger period and for an undetermined time after the completion of the merger.

The results of operations of Columbia after the merger may be affected by factors different from those currently affecting the results of operations of Columbia and West Coast.

The businesses of Columbia and West Coast differ in certain respects and, accordingly, the results of operations of the combined company and the market price of the combined company’s common stock may be affected by factors different from those currently affecting the independent results of operations of Columbia and West Coast. For a discussion of the business of Columbia and certain factors to be considered in connection with Columbia’s business, see “Information Concerning Columbia” and the documents incorporated by reference in this document and referred to under “Where You Can Find More Information”. For a discussion of the business of West Coast and certain factors to be considered in connection with West Coast’s business, see “Information Concerning West Coast” and the documents incorporated by reference in this document and referred to under “Where You Can Find More Information”.

The merger agreement limits West Coast’s ability to pursue an alternative transaction and requires West Coast to pay a termination fee of $20,000,000 under certain circumstances relating to alternative acquisition proposals.

The merger agreement prohibits West Coast from soliciting, initiating, encouraging or knowingly facilitating certain alternative acquisition proposals with any third party, subject to exceptions set forth in the merger agreement. See “The Merger Agreement—No Solicitation” included elsewhere in this joint proxy statement/prospectus. The merger agreement also provides for the payment by West Coast to Columbia of a termination fee of $20,000,000 in the event that the merger agreement is terminated in certain circumstances, involving, among others, certain changes in the recommendation of West Coast’s board of directors, a failure of West Coast’s shareholders to approve the merger agreement or the termination of the merger agreement in certain circumstances followed by an acquisition of West Coast by a third party. These provisions may discourage a potential competing acquiror that might have an interest in acquiring West Coast from considering or proposing such an acquisition. It should be noted, however, that the failure of West Coast shareholders to approve the merger agreement will not in and of itself trigger West Coast’s obligation to pay the termination fee, unless other factors, including a third-party acquisition proposal for West Coast made prior to the West Coast special meeting, also exist. See “The Merger Agreement—Termination; Termination Fee” included elsewhere in this joint proxy statement/prospectus.

The fairness opinions that Columbia and West Coast have obtained from KBW and Sandler O’Neill, respectively, have not been, and are not expected to be, updated to reflect any changes in circumstances that may have occurred since the signing of the merger agreement.

The fairness opinions issued to Columbia and West Coast by KBW and Sandler O’Neill, which are Columbia’s and West Coast’s respective financial advisors, regarding the fairness, from a financial point of view, of the consideration to be paid in connection with the merger, speak only as of September 25, 2012. Changes in the operations and prospects of Columbia or West Coast, general market and economic conditions and other factors which may be beyond the control of Columbia and West Coast, and on which the fairness opinions were based, may have altered the value of Columbia or West Coast or the market prices of shares of Columbia or West Coast as of the date of this document, or may alter such values and market prices by the time the merger is completed. KBW and Sandler O’Neill do not have any obligation to update, revise or reaffirm their respective opinions to reflect subsequent developments, and have not done so. Because West Coast and Columbia do not currently anticipate asking their respective financial advisors to update their opinions, the opinions will not

 

19

Table of Contents

address the fairness of the merger consideration from a financial point of view at the time the merger is completed. West Coast’s board of directors’ recommendation that West Coast shareholders vote “FOR” approval of the merger agreement and Columbia’s Board of Directors’ recommendation that Columbia shareholders vote “FOR” approval of the stock issuance, however, is made as of the date of this document. For a description of the opinions that Columbia and West Coast received from their respective financial advisors, see “Opinion of Columbia Financial Advisor” and “Opinion of West Coast’s Financial Advisor” included elsewhere in this joint proxy statement/prospectus.

The merger is subject to the receipt of consents and approvals from governmental entities that may impose conditions that could have an adverse effect on the combined company following the merger.

Before the merger may be completed, various approvals and consents must be obtained from the Federal Reserve Board, the Oregon Department of Consumer and Business Services and various other securities, antitrust, and other regulatory authorities. These governmental entities may impose conditions on the granting of such approvals and consents. Although Columbia and West Coast do not currently expect that any such material conditions or changes would be imposed, there can be no assurance that they will not be, and such conditions or changes could have the effect of delaying completion of the merger or imposing additional costs or limiting the revenues of the combined company following the merger, any of which might have an adverse effect on the combined company following the merger. In addition, each of Columbia and West Coast has agreed to use its reasonable best efforts to avoid or overcome impediments to completing the merger, including, among other things, making expenditures and incurring costs, raising capital, divesting or otherwise disposing of businesses or assets, and effecting the dissolution, internal merger or consolidation of subsidiaries or enhancing internal controls. Such actions may entail costs and may adversely affect Columbia, West Coast, or the combined company following the merger.

The merger is subject to certain closing conditions that, if not satisfied or waived, will result in the merger not being completed, which may cause the prices of Columbia common stock or West Coast common stock to decline.

The merger is subject to customary conditions to closing, including the receipt of required regulatory approvals and approvals of the Columbia and West Coast shareholders. If any condition to the merger is not satisfied or waived, to the extent permitted by law, the merger will not be completed. In addition, Columbia and West Coast may terminate the merger agreement under certain circumstances even if the merger agreement is approved by West Coast shareholders and the issuance of Columbia common stock in connection with the merger is approved by Columbia shareholders. If Columbia and West Coast do not complete the merger, the trading prices of Columbia common stock or West Coast common stock may decline to the extent that the current prices reflect a market assumption that the merger will be completed. In addition, neither company would realize any of the expected benefits of having completed the merger. If the merger is not completed and West Coast’s board of directors seeks another merger or business combination, West Coast shareholders cannot be certain that West Coast will be able to find a party willing to offer equivalent or more attractive consideration than the consideration Columbia has agreed to provide in the merger. If the merger is not completed, additional risks could materialize, which could materially and adversely affect the business, financial condition and results of Columbia or West Coast. For more information on closing conditions to the merger agreement, see “The Merger Agreement—Conditions to the Merger” included elsewhere in this joint proxy statement/prospectus.

The combined company expects to incur substantial expenses related to the merger.

The combined company expects to incur substantial expenses in connection with completing the merger and combining the business, operations, networks, systems, technologies, policies and procedures of the two companies. Although Columbia and West Coast have assumed that a certain level of transaction and combination expenses would be incurred, there are a number of factors beyond their control that could affect the total amount or the timing of their combination expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time. Due to these factors, the transaction and combination expenses

Table of Contents

associated with the merger could, particularly in the near term, exceed the savings that the combined company expects to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings related to the combination of the businesses following the completion of the merger. As a result of these expenses, both Columbia and West Coast expect to take charges against their earnings before and after the completion of the merger. The charges taken in connection with the merger are expected to be significant, although the aggregate amount and timing of such charges are uncertain at present.

The unaudited pro forma condensed combined financial information included in this document is preliminary and the actual financial condition and results of operations after the merger may differ materially.

The unaudited pro forma condensed combined financial information in this document is presented for illustrative purposes only and is not necessarily indicative of what Columbia’s actual financial condition or results of operations would have been had the merger been completed on the dates indicated. The unaudited pro forma condensed combined financial information reflects adjustments, which are based upon preliminary estimates, to record the West Coast identifiable assets acquired and liabilities assumed at fair value and the resulting goodwill recognized. The purchase price allocation reflected in this document is preliminary, and final allocation of the purchase price will be based upon the actual purchase price and the fair value of the assets and liabilities of West Coast as of the date of the completion of the merger. Accordingly, the final acquisition accounting adjustments may differ materially from the pro forma adjustments reflected in this document. For more information, see “Unaudited Pro Forma Condensed Combined Financial Information” beginning on page 30.

Shares of Columbia common stock to be received by West Coast shareholders as a result of the merger will have rights different from the shares of West Coast common stock.

Upon completion of the merger, the rights of former West Coast shareholders who receive Columbia common stock in the merger and thereby become Columbia shareholders will be governed by the certificate of incorporation and bylaws of Columbia. The rights associated with West Coast common stock are different from the rights associated with Columbia common stock. In addition, the rights of shareholders under Washington law, where Columbia is organized, may differ from the rights of shareholders under Oregon law, where West Coast is organized. See “Comparison of Rights of Holders of Columbia and West Coast Common Stock” beginning on page 116 for a discussion of the different rights associated with Columbia common stock.

Columbia has various provisions in its articles of incorporation that could impede a takeover of Columbia.

Columbia’s restated articles of incorporation contain provisions providing for, among other things, preferred stock, super majority approval of certain business transactions, and consideration of non-monetary factors in evaluating a takeover offer. Although these provisions were not adopted for the express purpose of preventing or impeding the takeover of Columbia without the approval of the Columbia board of directors, such provisions may have that effect. Such provisions may prevent former West Coast shareholders who receive shares of Columbia common stock in the merger from taking part in a transaction in which such shareholders could realize a premium over the current market price of Columbia common stock. See “Comparison of Rights of Holders of Columbia and West Coast Common Stock,” beginning on page 116.

Certain West Coast directors and officers may have interests in the merger different from the interests of West Coast shareholders.

In considering the recommendations of the board of directors of West Coast, West Coast shareholders should be aware that certain directors and executive officers of West Coast have interests in the merger that may differ from, or may be in addition to, the interests of West Coast shareholders generally. The board of directors of West Coast was aware of these interests and considered them, among other matters, when it adopted the merger agreement and in making its recommendations that the West Coast shareholders approve the Merger proposal. These interests include:

 

•

In accordance with the merger agreement, one of the directors of West Coast will be recommended to serve on Columbia’s board of directors and the board of directors of Columbia State Bank following the merger;

 

•

Certain of West Coast’s executive officers are party to change in control agreements that provide severance and other benefits following a change in control of West Coast in connection with a qualifying termination of employment and if such termination of employment occurred immediately following the merger, the executive officers with change in control agreements with West Coast would be entitled to receive severance payments and benefits equal to $3,752,966 for the five executive officers who are party to a change in control agreement and excise tax gross-ups for Mr. Sznewajs of $835,255, Mr. Giltvedt of $370,630 and for Mr. Bygland of $302,271.

 

•

Hadley Robbins and Xandra McKeown, both of whom are executive officers of West Coast, entered into employment agreements with Columbia (replacing existing change in control agreements with West Coast) that become effective upon the completion of the merger and pursuant to such employment agreements, if their employment is terminated (in a qualifying termination of employment) immediately following the effective time of the merger, they would be entitled to severance payments and benefits equal to $560,427 and $569,137 respectively, with Mr. Robbins also being entitled to a 280G excise tax gross-up that is equal to $438,998;

 

•

Accelerated vesting of restricted shares of West Coast common stock held by West Coast’s executive officers and non-employee directors with a total aggregate value (based on the average closing price of West Coast common stock over the first five business days following the public announcement of the merger) equal to approximately $955,000;

 

•

Accelerated vesting and, in most instances, payment of the supplemental executive retirement plans entered into with certain West Coast executive officers, with an aggregate acceleration value of $867,222 for all of the West Coast executive officers who participate in the supplemental executive retirement plan; and

 

•

West Coast directors and officers are entitled to continued indemnification and insurance coverage under the merger agreement.

For a more complete description of the interests of West Coast directors and executive officers in the merger, see “The Merger—Interests of West Coast’s Directors and Executive Officers in the Merger.”

RECENT DEVELOPMENTS

Results for Fourth Quarter of 2012 and Year Ended December 31, 2012

Columbia

On January 24, 2013, Columbia announced preliminary financial results for the quarter ended December 31, 2012 and the year ended December 31, 2012. Columbia reported net income of $46.1 million for the year ended December 31, 2012, compared to net income of $48.0 million for the year ended December 31, 2011. The net income for the quarter ended December 31, 2012 was $13.5 million, compared with net income of $14.8 million for the fourth quarter of 2011. The income for the year reflected a moderating trend in the accretion income related to the acquired loans in FDIC assisted transactions, which peaked during the last two quarters of 2011. At December 31, 2012, Columbia’s total assets were approximately $4.91 billion, an increase from total assets of approximately $4.79 billion at December 31, 2011. Loans excluding covered loans were $2.53 billion at December 31, 2012, an increase from loans, excluding covered loans of $2.35 billion at December 31, 2011. Covered loans were $420.5 million at December 31, 2012, a decrease from covered loans of $536.9 million at December 31, 2011. Total deposits were $4.04 billion at December 31, 2012, compared to total deposits of $3.82 billion at December 31, 2011. Total shareholders’ equity at December 31, 2012 was $764.0 million, an increase over total shareholders’ equity of approximately $759.3 million at December 31, 2011.

West Coast

On January 24, 2013, West Coast announced preliminary financial results for the fourth quarter and full year ended December 31, 2012. West Coast reported fourth quarter 2012 net income of $5.7 million or $0.26 per diluted share compared to net income of $17.8 million or $0.83 per diluted share in the fourth quarter of 2011. Fourth quarter 2011 net income reflected the impact from a reversal of a deferred tax asset valuation allowance. Net income for the full year 2012 was $23.5 million or $1.08 per diluted share compared to net income of $33.8 million or $1.58 per diluted share for the full year 2011. Fourth quarter 2012 total average loan balance of $1.48 billion declined $10 million or 1% from the preceding quarter, with declines primarily in commercial and real estate mortgage categories more than offsetting growth in commercial real estate balances. Total average loans also declined 1% year over year with a decline in commercial and real estate mortgage categories being offset by growth in commercial real estate and real estate construction categories. Net loan charge-offs in the final quarter of 2012 were $2.0 million or .53% of average loans on an annualized basis, representing a decline from $2.5 million or .67% in the same quarter of 2011. Total nonperforming assets at December 31, 2012, were $41.2 million or 1.66% of total assets, which represented a 42% reduction from $71.4 million or 2.94% of total assets a year ago. Average total deposits of $1.92 billion in the fourth quarter 2012 stayed essentially unchanged from the previous quarter, as the continued growth in non-interest bearing demand deposits offset declines in money market and time deposit balances. Year-over-year fourth quarter average total deposit balances declined $19 million or 1%, with average money market and time deposit balances declining $63 million and $47 million, respectively. Substantially offsetting these declines, non-interest bearing demand and savings deposits grew $81 million and $19 million, respectively, over the same period. Total assets as of December 31, 2012, were $2.49 billion compared to $2.43 billion as of December 31, 2011. Stockholders’ equity was $339 million as of December 31, 2012, compared to $314 million as of December 31, 2011. West Coast’s total risk-based capital ratio improved to 21.83% at December 31, 2012, up from 20.62% a year ago.

1.	The efficiency ratio has been computed as noninterest expense divided by the sum of net interest income on a tax equivalent basis and noninterest income excluding gains/losses on sales of securities.

2.	Interest earned on nontaxable securities has been computed on a 35% tax equivalent basis.

3.

Non-performing loan components are comprised of loans on non-accrual status (inclusive of non-accruing TDRs), plus any loans past due 90 days or more still on accrual. Accruing TDRs are not included in the non-performing loan calculation. West Coast’s rationale for this is that West Coast’s policy for moving non-performing TDRs to accrual status requires payment performance (typically six consecutive months), coupled with a reasonable assurance such performance will continue (as validated by current financial information).

 

As of 9/30/12:
Loans 90 days P/D on accrual			$     0
Nonaccrual TDRs		$	17.0mm
Other nonaccrual loans		$	15.4mm
Total nonperforming loans		$	32.4mm

SELECTED UNAUDITED PRO FORMA FINANCIAL DATA

The following table shows selected unaudited pro forma condensed combined financial information about the financial condition and results of operations of Columbia giving effect to the merger with West Coast. The selected unaudited pro forma condensed combined financial information assumes that the merger is accounted for under the acquisition method of accounting with Columbia treated as the acquirer. Under the acquisition method of accounting, the assets and liabilities of West Coast, as of the effective date of the merger, will be recorded by Columbia at their respective fair values and the excess of the merger consideration over the fair value of West Coast’s net assets will be allocated to goodwill.

The table sets forth the information as if the merger had become effective on September 30, 2012, with respect to financial condition data, and on January 1, 2011, with respect to the results of operations data. The selected unaudited pro forma condensed combined financial data has been derived from and should be read in conjunction with the unaudited pro forma condensed combined financial information, including the notes thereto, which is included in this joint proxy statement/prospectus under “Unaudited Pro Forma Condensed Combined Financial Information.”

The selected unaudited pro forma condensed combined financial information is presented for illustrative purposes only and does not necessarily indicate the financial results of the combined companies had the companies actually been combined at the beginning of the period presented. The selected unaudited pro forma condensed combined financial information also does not consider any potential impacts of current market conditions on revenues, potential revenue enhancements, anticipated cost savings and expense efficiencies, or asset dispositions, among other factors. Further, as explained in more detail in the notes accompanying the more detailed unaudited pro forma condensed combined financial information included under “Unaudited Pro Forma Condensed Combined Financial Information,” the pro forma allocation of purchase price reflected in the selected unaudited pro forma condensed combined financial information is subject to adjustment and may vary from the actual purchase price allocation that will be recorded at the time the merger is completed. Additionally, the adjustments made in the unaudited pro forma condensed financial information, which are described in those notes, are preliminary and may be revised.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial information and explanatory notes show the impact on the historical financial positions and results of operations of Columbia and West Coast and have been prepared to illustrate the effects of the merger involving Columbia and West Coast under the acquisition method of accounting with Columbia treated as the acquirer. Under the acquisition method of accounting, the assets and liabilities of West Coast, as of the effective date of the merger, will be recorded by Columbia at their respective fair values and the excess of the merger consideration over the fair value of West Coast’s net assets will be allocated to goodwill. The unaudited pro forma condensed combined balance sheet as of September 30, 2012 is presented as if the merger with West Coast had occurred on September 30, 2012. The unaudited pro forma condensed combined income statements for the year ended December 31, 2011 and the nine months ended September 30, 2012 are presented as if the merger had occurred on January 1, 2011. The historical consolidated financial information has been adjusted to reflect factually supportable items that are directly attributable to the merger and, with respect to the income statements only, expected to have a continuing impact on consolidated results of operations.

The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and does not necessarily indicate the financial results of the combined companies had the companies actually been combined at the beginning of the period presented. The adjustments included in these unaudited pro forma condensed combined financial statements are preliminary and may be revised. The unaudited pro forma condensed combined financial information also does not consider any potential impacts of potential revenue enhancements, anticipated cost savings and expense efficiencies, or asset dispositions, among other factors. For the historical income statements of West Coast, amounts related to other real estate owned, which were historically reported in noninterest income by West Coast, have been reclassified to noninterest expense to conform to the presentation in Columbia’s financial statements.

In addition, as explained in more detail in the accompanying notes to the unaudited pro forma condensed combined financial information, the pro forma allocation of purchase price reflected in the unaudited pro forma condensed combined financial information is subject to adjustment and may vary from the actual purchase price allocation that will be recorded at the time the merger is completed. Adjustments may include, but not be limited to, changes in (i) West Coast’s balance sheet through the effective time of the merger; (ii) the aggregate value of merger consideration paid if the price of Columbia’s stock varies from the assumed $18.85 per share; (iii) total merger related expenses if consummation and/or implementation costs vary from currently estimated amounts; and (iv) the underlying values of assets and liabilities if market conditions differ from current assumptions.

The unaudited pro forma condensed combined financial statements are provided for informational purposes only. The unaudited pro forma condensed combined financial statements are not necessarily, and should not be assumed to be, an indication of the results that would have been achieved had the transaction been completed as of the dates indicated or that may be achieved in the future. The preparation of the unaudited pro forma condensed combined financial statements and related adjustments required management to make certain assumptions and estimates. The unaudited pro forma condensed combined financial statements should be read together with:

 

•

the accompanying notes to the unaudited pro forma condensed combined financial statements;

 

•

Columbia’s separate audited historical consolidated financial statements and accompanying notes as of and for the year ended December 31, 2011, included in Columbia’s Annual Report on Form 10-K for the year ended December 31, 2011;

Notes to Unaudited Pro Forma Condensed Combined Financial Information

Note 1—Basis of Presentation

The unaudited pro forma condensed combined financial information has been prepared using the acquisition method of accounting giving effect to the merger involving Columbia and West Coast. The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and is not necessarily indicative of the financial position had the merger been consummated at September 30, 2012 or the results of operations had the merger been consummated at January 1, 2011, nor is it necessarily indicative of the results of operation in future periods or the future financial position of the combined entities. For the historical income statements of West Coast, amounts related to other real estate owned, which were historically reported in noninterest income by West Coast, have been reclassified to noninterest expense to conform to the presentation in Columbia’s financial statements. The merger, which is currently expected to be completed in the first quarter of 2013, provides for the issuance of 12,809,525 shares of Columbia common stock and $264.5 million in cash (subject to adjustment in certain circumstances). West Coast shareholders may elect to receive either cash, stock, or a unit consisting of a mix of cash and stock, in an amount equal to such holder’s pro rata share of the total merger consideration. The value of the per share merger consideration would be approximately $23.08 based upon a purchaser average closing price (as defined in the merger agreement) of $18.85.

Under the acquisition method of accounting, the assets and liabilities of West Coast will be recorded at the respective fair values on the merger date. The fair value on the merger date represents management’s best estimates based on available information and facts and circumstances in existence on the merger date. The pro forma allocation of purchase price reflected in the unaudited pro forma condensed combined financial information is subject to adjustment and may vary from the actual purchase price allocation that will be recorded at the time the merger is completed. Adjustments may include, but not be limited to, changes in (i) West Coast’s balance sheet through the effective time of the merger; (ii) the aggregate value of merger consideration paid if the price of Columbia’s stock varies from the assumed $18.85 per share; (iii) total merger related expenses if consummation and/or implementation costs vary from currently estimated amounts; and (iv) the underlying values of assets and liabilities if market conditions differ from current assumptions.

The accounting policies of both Columbia and West Coast are in the process of being reviewed in detail. Upon completion of such review, conforming adjustments or financial statement reclassification may be determined.

Note 2—Estimated Merger and Integration Costs

In connection with the merger, the plan to integrate Columbia’s and West Coast’s operations is still being developed. Over the next several months, the specific details of these plans will continue to be refined. Columbia and West Coast are currently in the process of assessing the two companies’ personnel, benefit plans, premises, equipment, computer systems, supply chain methodologies, and service contracts to determine where they may take advantage of redundancies or where it will be beneficial or necessary to convert to one system. Certain decisions arising from these assessments may involve involuntary termination of West Coast’s employees, vacating West Coast’s leased premises, changing information systems, canceling contracts between West Coast and certain service providers and selling or otherwise disposing of certain premises, furniture and equipment owned by West Coast. Additionally, as part of our formulation of the integration plan, certain actions regarding existing Columbia information systems, premises, equipment, benefit plans, supply chain methodologies, supplier contracts, and involuntary termination of personnel may be taken. Columbia expects to incur merger-related expenses including system conversion costs, employee retention and severance agreements, communications to customers, and others. To the extent there are costs associated with these actions, the costs will be recorded based on the nature and timing of these integration actions. Most acquisition and restructuring costs are recognized separately from a business combination and generally will be expensed as incurred. We estimated the merger related costs to be approximately $30 million and expect they will be incurred primarily in 2013.

Note 3—Estimated Annual Cost Savings

Columbia expects to realize $21 million in annual pre-tax cost savings following the merger, which management expects to be phased-in over a two-year period, but there is no assurance that the anticipated cost savings will be realized on the anticipated time schedule or at all. These cost savings are not reflected in the presented pro forma financial information.

Note 4—Pro Forma Adjustments

The following pro forma adjustments have been reflected in the unaudited pro forma condensed combined financial information. All taxable adjustments were calculated using a 35% tax rate to arrive at deferred tax asset or liability adjustments. All adjustments are based on current assumptions and valuations, which are subject to change.

 

Balance Sheet
(dollars in thousands)
A. Adjustments to cash and cash equivalents
To reflect cash used to purchase West Coast				$	(264,469	)
To reflect cash used to redeem West Coast junior subordinated debentures					(51,000	)
				$	(315,469	)
B. Adjustment to loans, excluding covered loans, net of unearned income
To reflect estimated fair value at merger date, calculated as 5% of the West Coast loan balance. The adjustment to loans is primarily related to credit deterioration in the acquired loan portfolio. During Columbia’s due diligence on West Coast, Columbia reviewed loan information across collateral types and geographic distributions. Columbia applied traditional examination methodologies to arrive at the fair value adjustment.				$	(74,538	)
C. Adjustment to allowance for loan and lease losses
To remove West Coast allowance at merger date as the credit risk is contemplated in the fair value adjustment in adjustment B above.				$	(31,457	)
D. Adjustment to premises and equipment
To reflect estimated fair value of West Coast properties at merger date, based on third-party estimates. The estimated useful life of these properties is 39 years.				$	15,000
E. Adjustment to goodwill
To reflect the goodwill associated with the West Coast merger.				$	182,409
F. Adjustment to core deposit intangible, net
To record the estimated fair value of acquired identifiable intangible assets, calculated as 1% of West Coast core deposits. Core deposits were identified as the demand, savings, money market accounts and certificates of deposit under $100,000. Although a core deposit study was not performed for the West Coast merger, the fair value adjustment of 1% was determined to be appropriate based on the valuation methodology utilized for Columbia’s prior acquisitions taken in conjunction with a review of West Coast’s historical deposit trends. A more detailed analysis will be completed upon closing of the merger. The acquired core deposit intangible will be amortized over 10 years using a sum-of-the-years-digits method. The estimated 10 year life was validated through review of the core deposit intangible lives utilized by our industry peers. The lives utilized by industry peers ranged from 5.5 to 15 years with an average of 9.25 years. Columbia felt the resiliency exhibited by West Coast’s deposit base over the past 5 years warranted a higher life than the average estimated useful life.				$	15,561

Note 5—Preliminary Purchase Accounting Allocation

The unaudited pro forma condensed combined financial information reflects the issuance of approximately 12,809,525 shares of Columbia common stock totaling approximately $241.5 million as well as cash consideration of approximately $264.5 million.

COMPARATIVE PER SHARE DATA OF COLUMBIA (UNAUDITED)

Presented below for Columbia and West Coast is historical, unaudited pro forma combined and pro forma equivalent per share financial data as of and for the year ended December 31, 2011 and as of and for the nine months ended September 30, 2012. The information presented below should be read together with the historical consolidated financial statements of Columbia and West Coast, including the related notes, filed by Columbia and West Coast, as applicable, with the SEC and incorporated by reference into this joint proxy statement/prospectus. See “Where You Can Find More Information.”

The unaudited pro forma and pro forma per equivalent share information gives effect to the merger as if the merger had been effective on December 31, 2011 or September 30, 2012 in the case of the book value data, and as if the merger had been effective as of January 1, 2011 in the case of the earnings per share and the cash dividends data. The unaudited pro forma data combines the historical results of West Coast into Columbia’s consolidated statement of income. While certain adjustments were made for the estimated impact of fair value adjustments and other acquisition-related activity, they are not indicative of what could have occurred had the acquisition taken place on January 1, 2011.

The unaudited pro forma adjustments are based upon available information and certain assumptions that Columbia management believes are reasonable. The unaudited pro forma data, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the impact of factors that may result as a consequence of the merger or consider any potential impacts of current market conditions or the merger on revenues, expense efficiencies, asset dispositions, among other factors, nor the impact of possible business model changes. As a result, unaudited pro forma data is presented for illustrative purposes only and does not represent an attempt to predict or suggest future results. Upon completion of the merger, the operating results of West Coast will be reflected in the consolidated financial statements of Columbia on a prospective basis.

Merger Consideration

In the merger, West Coast shareholders will have the right, with respect to each of their shares of West Coast common stock, to elect to receive, subject to proration and adjustment as described below, either cash, stock, or a unit consisting of a mix of cash and stock (with the percentage of cash comprising such unit equal to the percentage of the total consideration represented by cash), in an amount equal to your pro rata share (taking into account Class C Warrants and in-the-money stock options on an as-exercised basis and shares of common stock issuable upon conversion of Series B Preferred Stock (including shares of Series B Preferred Stock issuable upon exercise of Class C Warrants)) of the total consideration, which consists of $264,468,650 in cash (which may be increased in certain circumstances described below) plus the aggregate proceeds received by West Coast from the exercise of stock options between the execution of the merger agreement and the effective time of the merger (less any amounts paid to holders of West Coast stock options exercised during such period), plus the product of 12,809,525 shares of Columbia common stock multiplied by the volume weighted average price of Columbia common stock for the twenty trading day period beginning on the twenty fifth day before the effective time of the merger (the “Purchaser Average Closing Price”). The following table sets forth information concerning the approximate aggregate and per share consideration that would be payable in the merger based on different Purchaser Average Closing Prices. The table does not reflect the fact that cash will be paid instead of fractional shares, and does not account for any adjustments that may be made to the total cash amount in certain circumstances.

If the effective time of the merger does not occur on or prior to the later of (i) six months from the execution of the merger agreement (the “Six Months Date”) and (ii) April 1, 2013, and if West Coast’s consolidated total stockholders’ equity (subject to adjustment for certain unaccrued fees and expenses incurred in connection with the merger) exceeds $328,000,000, the aggregate merger consideration will be increased by an amount in cash equal to West Coast’s earnings during the period from the Six Months Date to the effective time of the merger less the amount of quarterly cash dividends paid by West Coast during such period. In addition, if the Purchaser Average Closing Price declined by more than 17.5% from the closing price of Columbia common stock on the day of the execution of the merger agreement, and Columbia’s common stock underperforms the Keefe

Bruyette & Wood (KBW) Regional Banking Index by more than 17.5% during such period, West Coast may terminate the merger agreement unless Columbia contributes sufficient additional cash consideration to offset any reduction in the value of the merger consideration attributable to such decline, as discussed in greater detail below. We sometimes refer to $264,468,650, plus the aggregate proceeds received by West Coast from the exercise of stock options between the execution of the merger agreement and the effective time of the merger (less any amounts paid to holders of West Coast stock options exercised during such period), plus any additional cash consideration paid by Columbia pursuant to the two preceding sentences, as the total cash amount. We sometimes refer to the product of 12,809,525 multiplied by the Purchaser Average Closing Price as the total stock consideration.

If you are a West Coast shareholder, whether you receive cash or Columbia common stock or a unit consisting of a mix of cash and stock as merger consideration, the value of the merger consideration that you will receive will fluctuate with the market price of Columbia common stock and will depend on the volume weighted average price of Columbia common stock for the twenty trading day period beginning on the twenty fifth day before the completion of the merger, and, if you receive Columbia common stock as merger consideration, on the market price of Columbia common stock when you receive the shares of Columbia common stock.

Cash Election

The merger agreement provides that each West Coast shareholder who makes a valid cash election will have the right to receive, in exchange for each share of West Coast common stock, subject to proration and adjustment as described below, an amount in cash equal its pro rata share (taking into account Class C Warrants and in-the-money stock options on an as-exercised basis and shares of common stock issuable upon conversion of Series B Preferred Stock (including shares of Series B Preferred Stock issuable upon exercise of Class C Warrants)) of the aggregate consideration, which consists of the total cash amount plus the total stock consideration (both as described above). This amount, which is referred to as the per share cash consideration, or the per share consideration, is calculated as the quotient obtained by dividing (a) the sum of (i) the aggregate consideration (which is equal to the total cash amount plus the total stock consideration) and (ii) the warrant and option proceeds (as defined below), by (b) the aggregate number of shares of West Coast common stock outstanding (including restricted shares, shares issuable upon conversion of Series B Preferred Stock (including shares of Series B Preferred Stock issuable upon exercise of West Coast’s Class C Warrants) and shares issuable upon exercise of West Coast stock options that have an exercise price below the per share consideration). For purposes of this calculation, the warrant and option proceeds are defined as the sum of (i) $24,000,000 and (ii) the aggregate proceeds that would be received by West Coast from the exercise of all West Coast stock options that have an exercise price below the per share consideration. For example, based on the volume weighted average price of Columbia common stock during the twenty trading day period ending January 31, 2013, the last practicable date before the printing of this document, and assuming no adjustments to the aggregate merger consideration are required pursuant to the discussion above concerning the delay in the completion of the merger or a greater than 17.5% decline in Columbia’s stock price, each West Coast common shareholder who receives cash for such shareholder’s shares would have the right to receive approximately $23.41 per share in cash. The aggregate amount of cash that Columbia has agreed to pay in the merger is fixed at the total cash amount and as a result, even if a West Coast shareholder makes a cash election, that holder may nevertheless receive a mix of cash and stock. If a West Coast shareholder makes a valid cash election, such holder’s shares are referred to as cash election shares.

Stock Election

The merger agreement provides that each West Coast shareholder who makes a valid stock election will have the right to receive, in exchange for each share of West Coast common stock, subject to proration and adjustment as described below, a number of shares of Columbia common stock equal to the exchange ratio (as defined below). We refer to this as the per share stock consideration. The exchange ratio is calculated as the quotient (rounded to the nearest ten-thousandth) obtained by dividing (a) the per share consideration by (b) the

Table of Contents

Purchaser Average Closing Price. No fractional shares of Columbia common stock will be issued in the merger, and a holder of West Coast common stock who would otherwise be entitled to a fractional share of Columbia common stock will receive cash in lieu thereof. Because the aggregate amount of cash that will be paid in the merger is fixed at the total cash amount, in the event that the total cash amount is undersubscribed, even if a West Coast shareholder makes a stock election, that holder may nevertheless receive a mix of cash and stock. If a West Coast shareholder makes a valid stock election, such holder’s shares are referred to as stock election shares.

Mixed Election

The merger agreement provides that each West Coast shareholder who makes a valid mixed election will have the right to receive the per share stock consideration in respect of the portion of such holder’s shares equal to the stock percentage (as defined below), rounded to the nearest whole share, and the per share cash consideration in respect of the portion of such holder’s shares equal to the cash percentage (as defined below), rounded to the nearest whole share. The cash percentage is equal to the total cash amount payable by Columbia as a percentage of the aggregate consideration (the value of the total cash amount and the total stock consideration payable by Columbia), which will fluctuate with the price of Columbia common stock during the during the twenty trading day period beginning on the twenty fifth day before the effective time of the merger, and the stock percentage is equal to one (1) minus the cash percentage. If a West Coast shareholder makes a valid mixed election, the shares with respect to which such holder has the right to receive the per share cash consideration are referred to as mixed cash shares and the shares with respect to which such holder has the right to receive the per share stock consideration are referred to as mixed stock shares.

Non-Election

West Coast shareholders who make no election to receive cash or shares of Columbia common stock in the merger, whose elections are not received by the exchange agent by the election deadline, or whose forms of election are improperly completed and/or are not signed will be deemed not to have made an election. West Coast shareholders not making an election may be paid in cash, Columbia common stock or a mix of cash and shares of Columbia common stock depending on, and after giving effect to, the adjustment procedures described below, the number of valid cash elections and stock elections that have been made by other West Coast shareholders, and the number of shares held by West Coast shareholders who provided notice of dissent to West Coast and do not vote in favor of the merger and who have not lost their right to dissenters’ rights (in the event that dissenters’ rights apply because shares of West Coast common stock cease to be registered on a national securities exchange, as discussed below) in accordance with the procedures and requirements of Oregon law (sometimes referred to as proposed dissenting shares). Shares of West Coast common stock with respect to which no election is deemed to have been made are referred to as no election shares.

Adjustment on a Prorated Basis

The cash and stock elections are subject to adjustment to ensure that the aggregate amount of cash that would be paid in the merger is equal to the total cash amount. As a result, even if a West Coast shareholder makes a cash election or stock election, such West Coast shareholder may nevertheless receive some stock consideration or some cash consideration, respectively.

Proration Adjustment if Cash Consideration is Oversubscribed

Shares of Columbia common stock may be issued to West Coast shareholders who make cash elections if the total cash amount is oversubscribed, meaning the aggregate cash amount that would be paid in the merger exceeds the total cash amount, in which case:

 

•

all mixed stock shares, stock election shares and no election shares will be converted into the right to receive the per share stock consideration;

 

•

all proposed dissenting shares (meaning all shares of West Coast common stock whose holders provide notice of dissent to West Coast prior to the West Coast special meeting and who do not vote in favor of

Table of Contents

the merger, in the event that dissenters’ rights apply to the merger (as discussed below)) will be deemed, for the purposes of proration, to be converted into the right to receive the per share cash consideration;

 

•

the exchange agent will select from among the cash election shares, by a pro rata selection process, a sufficient number of shares such that the aggregate cash amount that will be paid in the merger equals as closely as practicable the total cash amount, and all shares so selected will be converted into the right to receive the per share stock consideration (such shares are referred to as stock designated shares);

 

•

a West Coast shareholder making a cash election will receive:

 

•

the per share stock consideration for such holder’s shares that are stock designated shares; and

 

•

the per share cash consideration for such holder’s remaining shares; and

 

•

all mixed cash shares will be converted into the right to receive the per share cash consideration.

Example of Oversubscription of Total Cash Amount

As an example, assuming that the Purchaser Average Closing Price was equal to $19.44, and the total cash amount is $264,468,650, then the per share consideration would be equal to approximately $23.41 and the aggregate consideration would be equal to approximately $513.5 million, consisting of approximately $264.5 million in cash and 12,809,525 shares of Columbia stock valued at approximately $249.0 million. Under these assumptions, there would be a total of 11,810,061 shares of West Coast common stock exchangeable for cash consideration and 11,120,062 shares of West Coast common stock exchangeable for stock consideration in the merger (assuming all holders of Series B Preferred Stock elect to receive merger consideration, and treating all Class C Warrants and shares of Series B Preferred Stock on a common-equivalent basis).

Assuming that:

 

•

the number of cash election shares and mixed cash shares (and proposed dissenting shares, in the event that dissenters’ rights apply) combined is equal to 14,000,000, which would require the payment of approximately $327.8 million in cash (14,000,000*$23.41) (in other words, there is only approximately $264.5 million in total cash consideration, but based on the elections received approximately $327.8 million in cash would be paid in the merger),

then a West Coast shareholder that has made a valid cash election with respect to 1,000 shares of West Coast common stock would receive the per share stock consideration with respect to 156 shares (as rounded to the nearest whole share) of West Coast common stock and the per share cash consideration with respect to the remaining 844 shares (as rounded to the nearest whole share) of West Coast common stock. Therefore, that West Coast shareholder would receive 188 shares (as rounded to the nearest whole share) of Columbia common stock and approximately $19,749 in cash (as rounded to the nearest dollar). This example does not reflect any cash that may be paid in lieu of fractional shares of Columbia common stock.

Proration Adjustment if Cash Consideration is Undersubscribed

West Coast shareholders who make stock elections may receive cash in respect of some of their shares if the total cash amount is undersubscribed, meaning the aggregate cash amount that would be paid in the merger is less than the total cash amount, in which case:

 

•

all cash election shares and mixed cash shares will be converted into the right to receive the per share cash consideration;

 

•

all proposed dissenting shares will be deemed, for the purposes of proration, to be converted into the right to receive the per share cash consideration;

 

•

the exchange agent will select first from among the no election shares and then (if necessary) from among the stock election shares, by a pro rata selection process, a sufficient number of shares such that

Table of Contents

the aggregate cash amount that will be paid in the merger equals as closely as practicable the total cash amount (such shares are referred to as cash designated shares);

 

•

a West Coast shareholder making a stock election will receive:

 

•

the per share cash consideration for such holder’s shares that are cash designated shares; and

 

•

the per share stock consideration for such holder’s remaining shares;

 

•

all mixed stock shares and all no election shares that are not cash designated shares will be converted into the right to receive the per share stock consideration; and

 

•

all no election shares that are cash designated shares will be converted into the right to receive the per share cash consideration.

Examples of Undersubscription of Total Cash Amount

As an example, assuming that the Purchaser Average Closing Price was equal to $19.44, and the total cash amount is $264,468,650, then the per share consideration would be equal to approximately $23.41 and the aggregate consideration would be equal to approximately $513.5 million, consisting of approximately $264.5 million in cash and 12,809,525 shares of Columbia stock valued at approximately $249.0 million. Under these assumptions, there would be a total of 11,810,061 shares of West Coast common stock exchangeable for cash consideration and 11,120,062 shares of West Coast common stock exchangeable for stock consideration in the merger (assuming all holders of Series B Preferred Stock elect to receive merger consideration, and treating all Class C Warrants and shares of Series B Preferred Stock on a common-equivalent basis).

Scenario 1: Undersubscription of total cash amount and only no election shares are prorated into receiving cash consideration:

Assuming that:

 

•

the number of cash election shares and mixed cash shares (and proposed dissenting shares, in the event that dissenters’ rights apply) combined is equal to 10,000,000, which would require the payment of approximately $234.1 million in cash (10,000,000*$23.41) (in other words, there is approximately $264.5 million in total cash consideration, but based on the number of elections received only approximately $234.1 million in cash would be paid in the merger),

 

•

the number of stock election shares and mixed stock shares combined is equal to 8,000,000, which would require the payment of approximately $187.3 million in Columbia common stock (8,000,000*$23.41), and

 

•

there are 4,930,123 no election shares, which would require the payment of approximately $115.4 million (4,930,123*$23.41),

then a West Coast shareholder that has not made a valid election prior to the election deadline with respect to 1,000 shares of West Coast common stock would receive the per share stock consideration with respect to 633 shares (as rounded to the nearest whole share) of West Coast common stock and the per share cash consideration with respect to the remaining 367 shares (as rounded to the nearest whole share) of West Coast common stock. Therefore, that West Coast shareholder would receive 762 shares (as rounded to the nearest whole share) of Columbia common stock and approximately $8,595 in cash (as rounded to the nearest dollar). In this example, all stock election shares would receive the per share stock consideration.

Scenario 2: Undersubscription of total cash amount and both no election shares and stock election shares are prorated into receiving cash consideration

Assuming instead that

 

•

the number of cash election shares and mixed cash shares (and proposed dissenting shares, in the event that dissenters’ rights apply) combined is equal to 4,000,000, which would require the payment of

approximately $93.6 million in cash (4,000,000*$23.41) (in other words, there is approximately $264.5 million in total cash consideration, but based on the number of elections received only approximately $93.6 million in cash would be paid in the merger),

 

•

the number of mixed stock shares is equal to 6,000,000, which would require the payment of approximately $140.5 million in Columbia common stock (6,000,000*$23.41),

 

•

the number of stock election shares is equal to 6,000,000, which would require the payment of approximately $140.5 million in Columbia common stock (6,000,000*$23.41), and

 

•

there are 6,930,123 no election shares, which would require the payment of approximately $162.2 million (6,930,123*$23.41),

then a West Coast shareholder that has not made a valid election prior to the election deadline with respect to 1,000 shares of West Coast common stock would receive the per share cash consideration with respect to all 1,000 shares. Therefore, that West Coast shareholder would receive approximately $23,411 in cash (as rounded to the nearest dollar)
