Thanks, Mariner, and good morning, everyone. First, I'd like to provide an update on the integration of Marquette. In December 2014, we announced estimated transaction cost of $23 million in conjunction with our acquisition of Marquette. On Slide 11, you'll see that we have recognized acquisition cost of $14.8 million through March 31, 2016. As we expected, we completed the full conversion during the first quarter, so the largest portion of the expense has been recognized. Our latest projections indicate that we expect to come in better than anticipated with total transaction cost of approximately $20.2 million. Our teams have worked hard to make the integration a success and we truly applaud their efforts.
On the cost savings side, we anticipated acquisition-related synergies of approximately $14 million phased in over the 2-year period following the May 31, 2015 closing. Post conversion, our updated analysis shows that savings are estimated to be approximately $15.9 million, with $14.8 million realized to date. We expect the remaining $1.1 million in savings to be phased in throughout 2016 and into mid-2017.
Now turning to our first quarter results on Slide 12, you'll see our loan growth history. As Mariner mentioned, total loans at quarter end stood at $9.7 billion, an increase of 29.4% or $2.2 billion compared to a year ago. Acquired balances plus production through the legacy Marquette channels comprised $997.9 million of the increase in total loan balances. The remaining increase of $1.2 billion was generated through legacy UMB lenders for a year-over-year increase of 16%.
Credit quality remains sound, with 0.24% net charge-offs and 0.57% nonperforming loans, both as a percent of loans. Total securities available for sale in our investment portfolio stood at $6.9 billion at March 31, nearly flat compared to the end of the fourth quarter 2015 and an increase of $96.3 million or 1.4% from a year ago. The fact that we were able to hold our securities book to such a minor increase while we added $2.3 billion in deposits over the past year is a direct result of our ongoing strategy to rotate earning assets into loans. The details related to the composition of our investment portfolio in the past quarters' activities are shown on Slide 15.
Turning to the liability side, Slide 16 shows deposits for the first quarter of $15.4 billion, a $2.3 billion increase year-over-year, $744.1 million of which were attributed to the acquisition of Marquette and an increase of $325.6 million compared to the fourth quarter. The cost of interest-bearing liabilities for the first quarter was 22 basis points, and including noninterest-bearing deposits, it was 14 basis points.
Before we leave the balance sheet discussion, I'd like to touch on our asset sensitivity and market risk estimations. The boxes at the bottom of Slide 18 show the percentage of our loans with variable rates, which at March 31 stood at 48%, as well as the repricing details of our loan portfolio. The projected impact of hypothetical 12-month gradual changes in interest rates as well as the projected impact of immediate and sustained changes in rates is represented in the chart on that page.
Turning to the income statement. First quarter net interest income before provision rose 3% on a linked quarter basis and 30.5% year-over-year to $117.9 million. First quarter net interest margin of 2.79% is 33 basis points higher than in the first quarter 2015, driven once again by the growing loan portfolio, the addition of Marquette's higher-yielding loans and changes in our earning asset mix. Loans comprised 53% of average earning assets for the first quarter versus 47.4% for the same period last year. The linked quarter improvement in noninterest income was driven by $4.8 million in reduced losses and equity earnings on alternative investments. On a year-over-year basis, the 7.1% reduction in noninterest income was driven primarily by lower revenue from Scout. Year-over-year improvements in brokerage fees, driven by growing money market balances and increased 12b-1 fees and higher Bankcard fees due to record card purchase volume, slightly offset the reductions.
Slides 19 and 20 illustrate the components of the first quarter changes in noninterest income.
Looking at first quarter expenses on Slide 21, total noninterest expense increased $16.3 million or 9.9% year-over-year. The largest driver of the increase, salary and benefits expense, rose $8.6 million and included $8.3 million in Marquette salary and benefits that were not present in the first quarter 2015; $800,000 in Marquette-related severance; and $500,000 of non-Marquette-related severance. On a non-GAAP basis, operating noninterest expense, which excludes the impact of those severances and other items as described in the reconciliation, was $177.1 million, an increase of $2.2 million or 1.3% compared to the fourth quarter 2015, and $11.6 million or 7% compared to the first quarter of last year. Again, please see Slides 5 and 6 for additional detail regarding the non-GAAP reconciliations.
Now turning to the segments, I'll cover just a few highlights. The financials and drivers of performance for each segment are in the slides and press release. The Bank segment results begin on Slide 23 in the deck. Net interest income, both on a linked quarter basis and year-over-year basis benefited from increased loan balances, as well as from higher average earning asset yields, which came in at 2.93% for the first quarter compared to 2.88% for the fourth quarter 2015 and 2.56% for the first quarter of 2015. As a reminder, the largest portion of acquisition expense as well as ongoing Marquette salaries and benefit expense are recognized in the Bank segment.
Turning to Slide 24. We saw strong loan production in the first quarter, with lenders across all of UMB's lines of business adding $531.8 million in loans. Total payoffs and paydowns for the quarter were $283.5 million, which is slightly lower than the average of $318 million we saw over the prior 4 quarters.
Another metric we pay attention to is payoffs and paydowns as a percent of our loan portfolio, which has remained fairly steady. The composition of our loan book and a regional view are shown on Slides 25 and 26. We added $104.5 million in CRE loans and $80.9 million in construction loans during the quarter. By property type, office building and industrial projects were the largest-growing categories. Activity in Arizona was strong during the quarter, surpassing Missouri as the leader in new CRE commitments, thanks to strong production by our newly combined UMB and Meridian teams.
In addition, our agricultural lending group continues to have success, adding $136 million in loans over the last 12 months, an increase of 33.8%. Ag loans stood at $538.8 million at quarter end. Finally, we've added some additional detail on Slide 27 related to our outstanding oil and gas-related loans. At quarter end, these loans stood at $318.2 million and represented 3.3% of our total loan portfolio distributed by sector as shown on the slide. As of March 31, 2016, we had reserves of approximately 3.1% against our total outstanding oil and gas portfolio. Total company classified loans were $234.6 million at March 31. Of those, $61.9 million or 26.5% were oil and gas-related credits. Reserves against those classified oil and gas loans were approximately 11.4%. While overall oil and gas exposure remains relatively low and while we apply the same strong underwriting principles to these loans, we may have increased risk of loss on certain credits if oil prices do not normalize in the near term, and we are closely watching market conditions and our borrowers' financial positions.
Moving on from lending, I'll turn to Healthcare Services, which along with our credit and debit card products, is now part of the Bank segment. The number of HSA accounts grew to 826,000 at March 31 for a 36.7% year-over-year growth rate. And you'll see on Slide 32, at quarter end, Healthcare deposits stood at $1.4 billion and total HSA investment assets reached $140.4 million.
Following open enrollment periods in the fourth quarter of each year, we typically see balances build quickly in the first quarter as those accounts are funded. Total HSA deposits and assets grew 22% or $284.9 million from year-end 2015.
We remain very enthusiastic about our Healthcare business and its future prospects.
Lastly, looking at our total card purchase volumes on Slide 34, you'll see the components of the $2.7 billion first quarter card spend, the highest volume quarter-to-date for UMB. Interchange revenue generated in the first quarter was $20.7 million, an increase of 12.6% from the first quarter 2015.
Now I'll turn to the Institutional Investment Management segment, or Scout Investments business, with details beginning on Slide 35. Assets under management remained steady at $27.3 billion as of March 31, 2016. During the first quarter, Scout experienced net outflows of $701.1 million, a slowdown of 14.1% compared with the previous quarter. Robust fixed income markets provided a lift of $811 million. The components of equity and fixed income AUM changes are shown on Slide 37.
The revenue decline shown for the segment continue to be primarily driven by net outflows in the Scout Funds over the past several quarters, primarily in the International Fund and the resulting shift in AUM mix, which is currently 20% equity and 80% fixed income. We are focused on leveraging our Scout distribution channels in the institutional, intermediary and sub-advisory space and on continuing to improve performance, which is the best way to stem future outflows and ultimately return to net inflows. Several of our funds have experienced strong relative performance on a 1- and 3-year basis, as you can see on Slide 39. 5 of the 9 Scout Funds rated by Morningstar have overall ratings of 4 stars, and 1, our Scout Core Plus Bond Fund, has an overall rating of 5 stars.
On that slide and the following slide are some important disclosures related to those ratings.
Final segment I'll discuss today is our Asset Servicing segment, UMB Fund Services, which ended the first quarter with $180.7 billion in total assets under administration. The financials for the segment are shown on Slide 41. While revenue in the segment comes from a variety of sources including number of accounts and transaction fees, the largest driver is average AUA, which is greatly impacted by the health of the equity markets. Our Investment Management Series Trusts continued to gain ground with assets of $13.1 billion, 83 active funds and a strong pipeline. Slides 41 and 42 of the supporting materials show some additional metrics for our various products within Fund Services.
With that, I'll conclude our prepared remarks and turn it back over to the operator, who will open up the line for questions.
