Thank you, Melanie. This morning, we announced fourth quarter earnings of $13.5 million, or $0.34 per share. This compares to $14.8 million for the same quarter of 2011, or $0.37 per share. Our reported earnings decreased moderately from the same quarter last year due to the substantial positive impact acquisition accounting entries had on the fourth quarter 2011 earnings.
During the fourth quarter of 2011, we had net-of-tax earnings of $0.15, or $6 million and accretion income on the discounted loan portfolio, compared to less than $0.02, or $664,000, in the current quarter. Another significant item impacting the comparability of the fourth quarters of 2012 and 2011 is the other-than-temporary impairment charge of $3 million recognized in the fourth quarter of 2011 and recaptured during the current quarter. The combination of these 2 items was an increase of $0.10 per share for the fourth quarter of 2011.
We've provided a table in our earnings release illustrating the impact of certain accounting entries associated with our acquired loan portfolios. The net effect of acquired loan accounting resulted in reduced pre-tax income of $166,000 for the current quarter. This is a reduction of $2.8 million when compared to additional pre-tax income from acquired loans of $2.6 million for the third quarter of 2012, and reduction of $12.7 million from the fourth quarter of 2011.
I point out the dramatic reduction in the benefit of our acquired loan accounting from the prior year because it underscores the $0.04, or 15%, improvement in our core performance over the past 12 months. As I've mentioned in previous quarters, the individual components of our acquired loan accounting entries can change significantly by millions of dollars, in some cases, but the net change in the impact to earnings can be relatively inconsequential because of the offsetting nature of many of these entries.
It is true that these acquired portfolios, by their nature, decline over time, resulting in lower amounts of accretion income. However, for portfolios covered by loss-sharing agreements, the amount of the indemnification asset amortization expense will also decline. This is especially relevant for Columbia because 4 of our 5 FDIC deals are covered by loss-sharing agreements.
To underscore this point, during the fourth quarter, we recorded through interest income, $10.9 million in incremental accretion income on our covered loan portfolios. But we also reduced noninterest income by $9.7 million as a result of the change in our FDIC loss-sharing asset. When contemplating all the entries on these portfolios for the quarter, the pre-tax impact to income was a reduction of $166,000. This is a good example of our looking at accretion income in isolation will lead to inconsistent conclusions.
Tables on Pages 3 and 9 of our earnings release illustrate the ripple effect acquisition accounting has to our income statement, and capture the various items which should be considered side by side with accretion income. Our current estimate is that total accretion income on the covered portfolios will be roughly $57 million in 2013 and $40 million in 2014. Please keep in mind, these are just estimates and subject to adjustments, as expected cash flows on the covered loan portfolios change. While the spread between our reported and operating net interest margin will narrow, a substantial portion of the impact of earnings is mitigated by the decline in the amortization of the indemnification assets.
Our reported net interest margin for the fourth quarter was 5.15%, down from 7.14% for the same quarter last year to 5.52% for the third quarter of 2012. The operating net interest margin, which excludes the additional accretion income, was 4.14% for the fourth quarter compared to 4.4% and 4.44%, respectively, for the third and second quarters of 2012, and down from 4.49% in the first quarter of the year.
We spent considerable time optimizing the operating net interest margin during the fourth quarter with a view toward 2013 and beyond. I previously mentioned the prepayment of our Federal Home Loan Bank advances and gains realized in the securities portfolio. In December, we scrubbed our investment portfolio, liquidating and replacing roughly $86 million, or 9%, of the portfolio. The majority of the bonds sold were fast-paying, mortgage-backed securities, which due to the prepayment speeds, had negative yields. If all other variables remain constant, the combination of these 2 items will boost the operating net interest margin 6 basis points in the coming quarter.
While both of these actions improve the NIM, deposit growth and the buildup of cash needed for the closing of the West Coast Bancorp merger continue to drag on the margin. Average deposit growth of $153 million during the fourth quarter resulted in 14 basis points of margin compression. The $265 million in cash required to close the West Coast merger, decreases the margin 25 basis points. However, the margin impacted deposit growth and the cash portion of the merger consideration are somewhat interrelated. I separated the impact of the deposit growth because it underscores the quandary our industry faces. We know that attracting and retaining customer relationships is critical to our long-term success and we are pleased to see the proficiency our bankers exhibit in growing relationships on both sides of the balance sheet.
With our low cost of deposits, our growth is adding to incremental earnings, but these earnings come at the expense of softening the margins. While we have always maintained a disciplined approach to deposit pricing, we fine-tuned our offering rates during the fourth quarter. Our average cost of interest-bearing deposits for the current quarter was 18 basis points, down from 20 basis points in the prior quarter. Our cost of total deposits for the quarter was just 12 basis points, down from 14 basis points in the third quarter. Our biggest opportunity on the funding side will come from $379 million in certificates of deposits that will mature during 2013.
On a linked quarter basis, average interest earning asset yields decreased 36 basis points to 5.36% during the current quarter, down from 5.72% in the third quarter. The decrease in yield is due to lower interest rates on loan originations and decreased investment yields. We originated roughly $200 million in loans during the fourth quarter and in excess of $610 million for the year. The average rate on our non-covered loan portfolio was 4.94%, and it's down from 5.07% for the third quarter. New loans were originated during the fourth quarter at rates that are about 46 basis points lower than the existing portfolio. The linked quarter decline in loan origination rates moderated from the fourth quarter, dropping 7 basis points to 4.48% as compared to a 13 basis point decline in the third quarter.
The yield on the investment portfolio declined 17 basis points to 3.07% during the fourth quarter, as compared to 3.24% in the third quarter of 2012. The duration of the portfolio at December 31 was 3.63, up from 2.77 at the end of the third quarter. PTR rates for our mortgage-backed securities have slowed from the mid-20s, and at year end, are averaging in the low 20s. Still, we expect there will be significant cash flows reinvested at lower market rates during the coming quarters, putting additional downward pressure on the yield in the investment portfolio.
Total noninterest income was $6.6 million for the fourth quarter, an increase of $7.5 million from the third quarter. The increase was due in part to a reduction of $3.3 million in the change in the FDIC loss-sharing asset and the $3.7 million gain on investment securities.
One of our core performance measures is to compare noninterest income before the change in the FDIC loss-sharing assets. On this basis, the fourth quarter experienced an increase of $4.2 million over the third quarter of this year. After removing the securities gains, the linked quarter increase is $500,000, a little more than 4%. More importantly, this is up $1.3 million, or 12%, in the first quarter's run rate, driven in part by higher service charges, which increased roughly 8%.
Total noninterest expense was $37.8 million for the current quarter, down from $40.9 million in the third quarter and $39.9 million in the second quarter of 2012. Our run rate for noninterest expense is another core performance measure we track, but it takes some math to arrive at a comparable number. The current quarter includes $649,000 of merger expense, $1.4 million in net benefit from OREO and $154,000 in claw back liability recapture. After taking these items into consideration, our noninterest expense run rate for the quarter is $40 million. On the same basis, the run rate for the third quarter of 2012 was $40.6 million.
Compensation and benefit expense and occupancy are the 2 drivers of the reduced run rate. If you look at the fourth quarter of 2012, in comparison to the fourth quarter of 2011, similar improvement in the expense run rate is noted. The run rate for the fourth quarter of 2011 was $41.6 million, $1.6 [ph] million or 3.8% higher than the current period.
The continued improvement in our noninterest income and noninterest expense run rate on a linked quarter and prior year basis is the result of the ongoing efforts of our line of business leaders. Through their actions during 2012, we optimized our fee schedules while increasing our realization of accessible fees, fine-tuned our retail staffing model and developed a framework for allocating resources across our various customer delivery channels. In conjunction with these initiatives, we reduced our FTE count by 50 during 2012, mostly through attrition, and consolidated 3 branches during the second half of 2012, which will result in additional expense efficiencies for 2013.
Lastly, at December 31, our total risk-based capital ratio exceeded 20%, our leverage ratio was approximately 12.8% and our tangible common equity to tangible assets ratio was 13.3%. Prudent management of capital is a priority for us and as 2013 progresses, we will consider all reasonable means of capital utilization.
Now, I will turn the call over to Andy McDonald.
