Thanks, Mariner, and welcome, everyone. First, I will review our company’s financials and then provide a more detailed summary of our 4 business segments. Beginning with the balance sheet, average earning assets increased 8.9% to $12.1 billion. The average balance in our investment portfolio was $6.6 billion, 1.1% higher than the last quarter and 14.5% higher than third quarter year ago.
The average yield on securities was 2.13%, a decline of 9 basis points from last quarter and a decline of 24 basis points from the third quarter of 2011. Activity during the third quarter included the roll-out of $355 million in core portfolio securities at an average yield of 2.35%. In turn we purchased $362 million of securities at an average yield of 1.41%. The average life is now 42.57 months up from 35.45 months last quarter.
The average life in the third quarter of 2011 was 33.84 months. Changes in the portfolio along with some modifications to our security modeling, inputs and tools lengthened the duration to 38.7 months from 28.29 months in the second quarter. Over the next 3 months, $385 million in core investments with an average yield of 2.24% will cash flow and over the next 12 months $1.4 billion of core investments with an average yield of 2.04% will cash flow. Additionally, 72% of our loan portfolio is expected to reprice or mature in the next 12 months. As we have reported, the securities mix in our portfolio has shifted and approximately 50% of the total was invested in mortgage backed securities at the end of the quarter. We continually monitor our amortization risk and have seen only a slight increase in 2012.
Our current average book price on this portion of our portfolio is $101.51 as compared to $101.63 at year end 2011. Allowance for loan losses is $71.4 million and allowances as a percent of total loans is now 1.32% compared to 1.53% a year ago. Although our allowance as a percent of loans has decreased, we believe this level is appropriate given the high quality of our loan portfolio and the history of charge-offs.
Our coverage ratio is more than 2.6x the amount of non-performing loans while the median industry allowance recorded for the second quarter would coverage just over half of non-performing loans. We remain well capitalized with Tier I, leverage and total risk based capital ratios of 11.69%, 7.15% and 12.62% respectively. Looking at the liability side of the balance sheet, our average deposits increased by 9.7% to $10.4 billion.
Average non-interest bearing deposits comprise more than 40% of our total deposits which puts us in the top 3% of the industry according to SNL Financial. Our high percentage of free funds is a competitive advantage and is reflected in our low cost of funds.
Our overall cost of funds was 24 basis points for the third quarter versus 36 basis points a year ago. If you factor in free funds this brings the number down to just 15 basis points. Shareholder equity was $1.3 billion, a 10.6% increase from a year ago. Since the beginning of 2008, equity has increased by 45.3%. We have experienced consistent organic growth and equity and have been able to deploy it effectively to make acquisitions. Additionally, total shareholder return from October 2007 to October 2012 was 17%.
For the same period returns from the S&P 500 and SNL U.S. Bank Index were 3% and negative 47.7% respectively. Reviewing other financial highlights, return on average assets was 0.79% for the quarter compared to 0.85% in third quarter 2011. Return on average equity for the quarter was 8.12% compared to 8.81% a year ago.
Turning to the income statement for the third quarter 2012. Net interest income was $80.4 million, up 1.6% from a year ago and virtually unchanged from second quarter 2012. As I mentioned, average earning asset balances increased by 8.9%. However, the changing mix resulted in a lower overall yield of 2.94% down 27 basis points from 3.21% for the third quarter of 2011. Average net interest margin for the quarter decreased 18 basis points from a year ago to 2.8%.
On a linked quarter basis we saw a 2 basis point decline in net interest margin. As Mariner mentioned, non-interest income increased 5.3% from the third quarter of 2011 to $106.3 million. The primary driver of this growth was trust and securities processing revenue which increased 8.4%. This increase was partially offset by lower gains on the sale of securities during the quarter. As a reminder we had security gains of $2.4 million in the third quarter of 2011 compared to gains of only $259,000 in the third quarter of 2011.
As you may recall, in the first quarter of this year we made an $8.2 million adjustment in contingent liabilities due to new accounting rules related to the earn-out agreements on some of our acquisitions. We review these liabilities quarterly and determined that there was not a need for a material adjustment in the third quarter. We will continue to monitor these liabilities and you should expect us to have some future adjustments either up or down throughout the earn out period.
For the third quarter non-interest expense increased by 4.6% to a $145.9 million. This $6.5 million increase was driven primarily by higher salary and benefits expense of $3.9 million and the recognition of increased marketing and business development of $2.5 million due to the timing of those expenses.
As Mariner discussed, part of our ongoing effort to drive growth includes investments in resources such as systems, advertising and business development and people. We believe investments such as these and progress made on our other growth strategies will positively impact our results over the long run. For the third quarter our efficiency ratio was 74.29% virtually unchanged from 74.22% in the third quarter 2011.
For the 9 months ended September 30, our efficiency ratio was 72.17% compared to 74% in the same period a year ago. Now let me review the results of our 4 business segments.
Looking first at institutional investment management. Net income before tax was $7.6 million, an increase of 58.3% when compared to $4.8 million in the third quarter of 2011. Total non-interest income in this segment increased by 14.8% to $24.8 million and non-interest expense increased by 2.3% to $17.2 million compared to the third quarter a year ago.
The pretax profit margin for institutional investment management was 30.7% for the third quarter, improving from 22.2% in the third quarter of 2011. Net income before tax and asset servicing increased by $931,000 or 120.8% to $1.7 million for the quarter. Peter will provide more details on the driver of this segment later in the call. Total non-interest income for the segment increased about 7.8% to $18.3 million and non-interest expense increased by 2.1% to $17 million compared to the third quarter of 2011.
The pretax profit margin for asset servicing was 9.1% for the third quarter improving from 4.4% a year ago. In payment solutions, non-interest income increased by 9.8% to $15.4 million and non-interest expense increased by 34% to $17.7 million compared to the third quarter of 2011. The resulting pretax net income was $6.2 million, a reduction of 31.2% from year ago. Expenses and payment solutions include payment processing fees which fluctuate based on transaction volumes. As the total number of credit and debit card accounts grow, the transactions and spending related to these accounts will drive additional processing fees. Also impacting non-interest expense for the segment this quarter were additional salary and benefit expense for newly added sales and operational positions, consulting and legal fees related to new products and services and a timing difference of cash payments and accruals related to advertising initiatives.
The pretax profit margin for payment solutions was 23.6% for the third quarter. Finally our fourth segment, the bank, posted net income before tax of $20.8 million for the quarter compared to $21.5 million a year ago, a decrease of 3.4%. Total non-interest income for the segment decreased by 1.1% to $47.9 million. The primary driver of this decrease was the reduced gains on the sale of securities.
Net interest income for the segment was up by 2% to $69.1 million. Non-interest expense for the bank increased by 1.3% to $94 million compared to a year ago. The pretax profit margin for the bank was 17.8% for the quarter. With that I will turn the call over to Peter to discuss the drivers behind our business results.
