TACOMA, Wash., Jan. 24, 2013 /PRNewswire/ -- Melanie Dressel, President and Chief Executive Officer of Columbia Banking System and Columbia Bank (NASDAQ: COLB) ("Columbia") said today upon the release of Columbia's fourth quarter 2012 earnings, "Our core performance measures continue their positive trend, the result of our ongoing strategic initiatives. These initiatives have resulted in solid loan growth, improved credit quality metrics, as well as increased levels of noninterest income, coupled with reduced expenses."

Ms. Dressel continued, "In general, our core performance measures for the fourth quarter 2012 and the full year 2012 are improved when compared to the results of the same periods in the prior year. Prior period comparisons are distorted by the favorable impact resulting from one of our FDIC-assisted acquisitions, which bolstered earnings during the fourth quarter of 2011 by $0.15 per share, or $6 million. With loan growth of 8%, our high level of core deposits and the pending merger with West Coast Bancorp, we feel we are well-positioned heading into 2013."

Columbia's net income was $13.5 million for the quarter ended December 31, 2012 compared to net income of $14.8 million for the same quarter of 2011. Earnings per diluted common share were $0.34 for the fourth quarter, compared with earnings of $0.37 per diluted common share a year earlier. The decline in earnings was due to the enhanced benefits realized in the fourth quarter of 2011 from Columbia's FDIC-assisted transactions.

Significant Influences on the Quarter Ended December 31, 2012

Net Interest Margin

Columbia's net interest margin decreased to 5.15% for the fourth quarter of 2012, down from 7.14% for the same period last year and down from 5.52% for the third quarter of 2012. Columbia's net interest margin is impacted significantly by the accounting for acquired loans. The net interest margin for the current quarter reflects a moderating trend in the incremental accretion income related to the acquired loans, which peaked during the last six months of 2011.

Columbia's net interest margin, excluding incremental accretion income, interest reversals on nonaccrual loans and prepayment charge on Federal Home Loan Bank advances, decreased to 4.14% for the fourth quarter of 2012, down from 4.68% for the same period last year and down from 4.40% for the third quarter of 2012. The net interest margin, excluding incremental accretion income, was negatively impacted during the fourth quarter of 2012 by the overall decreasing trend in rates, impacting both the loan and investment portfolios. The average yield on investments declined as portfolio cash flows were reinvested at lower prevailing rates. Also contributing to the lower net interest margin was the additional cash held in overnight funds in anticipation of payment of the cash portion of the West Coast Bancorp merger consideration.

Ms. Dressel commented, "Our operating net interest margin compressed during the current quarter at a similar rate as much of the industry experienced in the previous quarter. During the fourth quarter, we executed on several initiatives to supplement the net interest margin in 2013, the results of which were beginning to be realized in December."

The following table shows the impact to interest income and the related impact to the net interest margin resulting from accretion of income on acquired loan portfolios for the periods presented.

The incremental accretion income in the table above represents the amount of income recorded on acquired loans above the contractual rate stated in the individual loan notes and stems from the discount established at the time these loan portfolios were acquired. At December 31, 2012, the accretable yield on acquired impaired loans was $166.9 million and the net discount on other acquired loans was $2.4 million. The accretable yield and net discount represent income to be recorded by Columbia over the remaining life of the acquired loans. Accretable yield is subject to change based upon expected future loan cash flows, which are re-measured by Columbia on a quarterly basis.

The $2.5 million net provision for losses on covered loans in the current period is partially offset by an 80%, or $2.0 million, benefit to the change in the FDIC loss-sharing asset, resulting in a negative net pre-tax earnings impact of $502 thousand. The provision for losses on covered loans was primarily due to decreased expected future cash flows as re-measured during the current quarter when compared to the prior quarter's re-measurement.

The $9.7 million change in the FDIC loss-sharing asset in the current quarter negatively affected noninterest income and consists of $9.5 million of scheduled amortization expense and approximately $2.2 million of expense related to covered other real estate owned partially offset by the $2.0 million favorable adjustment described above.

Balance Sheet

Ms. Dressel commented, "Our focus on developing and enhancing customer relationships resulted in 8% growth in noncovered loans and a 12% increase in our business loans from the end of last year." Noncovered loans were $2.53 billion at December 31, 2012, up 2% from $2.48 billion at the prior quarter and up 8% from $2.35 billion at prior year end. Net noncovered loan growth was approximately $49 million from prior quarter and $177 million from prior year end. The growth in noncovered loans for the quarter was centered in commercial and multifamily residential real estate loans and commercial and multifamily residential real estate construction loans. At December 31, 2012, Columbia's total assets were $4.91 billion, a 3% increase from $4.79 billion in total assets at prior year end and virtually unchanged from the prior quarter. Securities, including FHLB stock, were $1.02 billion at December 31, 2012, up 6% from $965.6 million at the prior quarter and down 3% from $1.05 billion at prior year end.

Total deposits at December 31, 2012 were $4.04 billion, a 3% increase from $3.94 billion at September 30, 2012, and a 6% increase from $3.82 billion at December 31, 2011. Core deposits comprised 94% of total deposits, and were $3.80 billion at December 31, 2012, an increase of 3% from $3.69 billion at September 30, 2012, and an increase of 8% from $3.51 billion at December 31, 2011.

During the fourth quarter of 2012, the Company repaid $106.4 million of FHLB advances. Associated with this repayment, the Company incurred $603 thousand in prepayment expense.

Total shareholders' equity was $764.0 million at December 31, 2012, compared to $762.0 million and $759.3 million at September 30, 2012 and December 31, 2011, respectively. In accordance with the Columbia's recent capital and dividend strategies, total shareholders' equity has remained relatively unchanged over the past four quarters.

Asset Quality

At December 31, 2012, nonperforming noncovered assets were $48.5 million, a decrease of 9% from $53.3 million at September 30, 2012, and 43% from $85.4 million at December 31, 2011. Nonaccrual loans declined $4.2 million during the fourth quarter. The decrease in nonaccrual loans for the quarter was driven by payments of $4.4 million, charge-offs of $2.7 million, the return of $2.5 million of nonaccrual loans to accrual status, and $935 thousand of loans transferred to OREO, partially offset by $6.3 million of new nonaccrual loans. Noncovered other real estate owned (OREO) and other personal property owned (OPPO) were reduced by $641 thousand during the fourth quarter, as a result of $991 thousand in sales and $585 thousand in write-downs, partially offset by loan foreclosures of $935 thousand. Columbia's allowance for loan losses to nonperforming, noncovered loans ratio was 140% for the quarter, up from 124% for the third quarter 2012 and 99% for the same period last year.

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

For the fourth quarter of 2012, Columbia made a provision of $2.4 million for noncovered loan losses. For the comparable quarter last year the company made a provision of $4.8 million. The provision for noncovered loan losses during the current quarter was primarily driven by net charge-offs realized in the quarter and to a lesser extent by the $49 million in noncovered loan growth experienced during the quarter.

The allowance for noncovered loan losses to period end loans was 2.07% at December 31, 2012 compared to 2.08% at September 30, 2012 and 2.26% at December 31, 2011.

Fourth Quarter 2012 Operating Results

Quarter ended December 31, 2012

Net Interest Income

Net interest income for the fourth quarter of 2012 was $54.9 million, a decrease of 24% from $72.1 million for the same quarter in 2011, primarily due to the accretion income recorded during the fourth quarter of 2011 related to our acquired loan portfolios. During the fourth quarter of 2012, the Company recorded $11.9 million in incremental accretion income on acquired loans compared to $26.4 million for the fourth quarter of 2011.

Compared to the third quarter of 2012, net interest income decreased 4% from $57.3 million primarily due to lower yields on the loan and securities portfolios.

Noninterest Income (Loss)

Total noninterest income was $6.6 million for the fourth quarter of 2012, compared to a loss of $9.6 million for the fourth quarter of 2011. The increase from the prior-year period was due to a combination of the change in the FDIC loss-sharing asset, which accounted for $7.8 million of the increase, and an increase of $6.5 million in investment securities gains. The increase in securities gains was primarily due to the $3.0 million gain recorded in the current quarter on a municipal bond that was determined to be other than temporarily impaired in the fourth quarter of 2011. The Company received full payment on this security in the current quarter.

The following table reflects the components of the change in the FDIC loss-sharing asset for the three month periods indicated.

Noninterest Expense

Total noninterest expense for the fourth quarter of 2012 was $37.8 million, a decrease of 9% from $41.3 million for the same quarter in 2011. The decrease from the prior-year period was due to a decrease of $830 thousand in compensation and benefits, $642 thousand in occupancy and $992 thousand in other noninterest expense as well as an increase of $834 thousand in net benefit of operation of other real estate. These decreases were partially offset by a $1.1 million increase in legal and professional fees, which includes $649 thousand of costs recorded during the fourth quarter of 2012 related to the announced merger with West Coast Bancorp.

Compared to the third quarter of 2012, noninterest expense decreased $3.1 million, or 8%. The decrease was primarily attributable to a decrease of $1.0 million in advertising and promotion, $573 thousand in compensation and benefit expense, and a $489 thousand change in the FDIC clawback liability.

Organizational Update

Melanie Dressel commented, "As an important component of our ongoing effort to improve efficiencies without compromising customer service, we continually evaluate the profitability of our customer delivery channels. A total of three branches were closed during 2012; during the fourth quarter, we consolidated our Port Townsend and Belfair branches, both located in grocery stores in Washington, into nearby, full-service locations."

Ms. Dressel continued, "As we announced last quarter, we signed a definitive merger agreement with West Coast Bancorp ("West Coast") headquartered in Lake Oswego, Oregon. After the merger, Columbia will rank as the number one community bank in deposit market share in both Oregon and Washington, and we will have extensive coverage throughout both states with about 150 branches and over $7 billion in assets. We expect this transaction to be completed within the next three months, subject to the approval of the shareholders of each company and the necessary regulatory approvals."

Cash Dividend Announcement

The Board of Directors announced that a quarterly cash dividend of $0.10 per common share will be paid on February 20, 2013 to shareholders of record on February 6, 2013. This is an increase of 11% from $0.09 paid the prior quarter.

These forward looking statements describe Columbia's management's expectations regarding future events and developments such as future operating results, growth in loans and deposits, continued success of Columbia's style of banking and the strength of the local economy. The words "will," "believe," "expect," "intend," "should," and "anticipate" and words of similar construction are intended in part to help identify forward looking statements. Future events are difficult to predict, and the expectations described above are necessarily subject to risk and uncertainty that may cause actual results to differ materially and adversely. In addition to discussions about risks and uncertainties set forth from time to time in Columbia's filings with the Securities and Exchange Commission, available at the SEC's website at www.sec.gov and the Company's website at www.columbiabank.com, including the "Risk Factors," "Business" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" sections of our annual reports on Form 10-K and quarterly reports on Form 10-Q, factors that may cause actual results to differ materially from those contemplated by such forward-looking statements include, among others, the following: (1) local, national and international economic conditions may be less favorable than expected or have a more direct and pronounced effect on Columbia than expected and adversely affect Columbia's ability to continue its internal growth at historical rates and maintain the quality of its earning assets; (2) changes in interest rates may reduce interest margins more than expected and negatively affect funding sources; (3) projected business increases following strategic expansion or opening or acquiring new branches may be lower than expected; (4) the proposed merger with West Coast Bancorp may not close when expected or at all because required regulatory, shareholder or other approvals and other conditions to closing are not received or satisfied on a timely basis or at all, which may have an effect on the trading prices of Columbia's stock; (5) costs or difficulties related to the integration of acquisitions may be greater than expected; (6) competitive pressure among financial institutions may increase significantly; and (7) legislation or regulatory requirements or changes may adversely affect the businesses in which Columbia is engaged. We believe the expectations reflected in our forward-looking statements are reasonable, based on information available to us on the date hereof. However, given the described uncertainties and risks, we cannot guarantee our future performance or results of operations and you should not place undue reliance on these forward-looking statements.
