Thanks, Johnny. What a great quarter and a great year. Congratulations to all our employees for a very successful 2012. As Johnny said, the fourth quarter of 2012 was the most profitable quarter in the history of our company. I look back at my notes and as I said in previous calls, we have been able to make that statement for all of the conference calls this year, improvement each and every quarter of the year. This quarter, the company increased its earnings above our previously recorded record earnings by $844,000 for 5.2%. We are very encouraged by this result and there will be more to say on the income numbers.
Now there was a lot of activity or noise, as Johnny said, however you want to say it, it all happened in the fourth quarter. First of all, we were able to acquire Heritage Bank with 3 branches in the Tampa area as an FDIC failed bank transaction on November 2. We are very pleased with this addition to our central Florida region. This was a whole bank walk away transaction in which the FDIC retained all non-performing loans in OREO.
After the dust settled, we retained $134 million in loans before any discount and $151 in deposits. And as you might recall, last quarter, we announced that we entered into an asset purchase agreement with Premier Bank Holding Company in Tallahassee, as part of a 363 bankruptcy proceeding. I am pleased to announce that as of December 1, 2012 the purchase was complete and the bank is now part of this Centennial family. In this transaction, we retained $167 million before any discount in loans and $237 million in deposits and added 6 branches. We are currently in the process of evaluating those branches and there will savings in the consolidation process.
Speaking of which, both of these banks have already started the conversion process to our systems and backroom that will be completed on March 8 for Heritage Bank and April 19 for Premier. As we have said before, we believe that conversion is essential to the process of improving net income growth for these acquisitions. So we immediately began that process. Both of these acquisitions are accretive and we look forward to seeing how well they perform for full quarter in 2013 as well as post conversion as we consolidate the backroom functions.
Due to these acquisitions and included in the fourth quarter numbers as Johnny has said was a $5.2 million gain from the Heritage acquisition, along with $5.2 million in merger expenses associated with both Heritage and the Premier mergers. So they kind of offset one another.
So a very busy fourth quarter for acquisitions. And I want to add that we are continuing to be active in the hunt for more. We are very busy right now, looking at banks as well as organic growth opportunities for the right strategic addition to our organization.
Now let’s get back to income and the key components of these record numbers. First of all, as I said, net income. The fourth quarter net income was $16.9 million or $0.60 diluted earnings per common share, compared to $14.2 million of net income or $0.50 diluted earnings per common share for the same quarter of 2011, an increase of $0.10 per share or 20%.
Diluted earnings per common share including intangible amortization for the fourth quarter of 2012 was $0.62 compared to $0.51 diluted earnings per common share, excluding intangible amortization for the same period in 2011. We are really encouraged with these numbers, but when you compare the last 2 years it really puts everything in perspective. Net income for the year 2012 was $63 million, compared to $54.7 million for the year ended 2011.
Diluted earnings per share for the year ended 2012 was $2.23 per share, compared to $1.85 per share for 2011, an increase of $0.38 per share or 20.5%. Return on assets or normalized earnings ended at 1.67%, compared to 1.56% at 12/31/11, and our ROA excluding intangible amortization ended at 1.75% as compared to 1.64% at 12/31/11. Core ROA that excludes intangibles provisions, merger expenses and taxes ended at a very strong 2.88%. Our return on average TCE, excluding intangible amortization was 16.4%, as compared to 12/31/11 at 14.57%.
As we’ve said throughout the year and emphasized by Johnny, our high performing Arkansas banks continue to produce record numbers and we’re really starting see marked improvement in Florida and the Alabama regions. With the strong Arkansas, it is good to see this happen with the trend of income growth. In fact just based upon internal numbers we are seeing ROAs in both Florida and Alabama in excess of 1% on a year-to-date basis.
At the Centennial Bank level and on internal analysis, 54% of all assets are in Arkansas, 6% of assets are in Alabama and 40% of assets are in Florida. Contributing to these great numbers was our ability to continue to control our expenses and improve that throughout the year. We ended the quarter with a 44.4% core efficiency ratio or an improvement of 436 basis points from the same period of the previous year.
We continue to be pleased with this. And to tell you a little more about it, I'm very pleased to turn it over to Donna Townsell, our Vice President for Corporate Efficiency and she's going to tell us a little bit about some new programs that we're starting on the revenue side.
