Thanks, Steve. As noted on Slide 7, we saw healthy growth in net interest revenue and net interest margin in the first quarter. Net interest margin was 2.81% during the quarter, up 12 basis points sequentially as we saw a significant increase in loan yields with a modest increase in cost of interest-bearing liabilities. We're also seeing better yields from our portfolio of available-for-sale securities.
On Slide 8, fees and commissions were $164.4 million for the first quarter, up 1.4% on a sequential basis and relatively flat year-over-year. Brokerage and trading was up 18% sequentially, largely due to the nonrecurrence of the $5 million trading securities mark-to-market that impacted the fourth quarter, [indiscernible] back to the post-election interest rate spike. Excluding this, brokerage and trading revenue would've been flat sequentially as increases in retail brokerage and derivative fees and commissions were offset by lower investment banking revenue.
Transaction card, which, as you know, has seasonal elements to it, was down slightly year-over-year. However, sales activity has been robust recently in the ATM network business and we feel good about revenue growth prospects in the transaction card revenue line over the balance of 2017.
Fiduciary and asset management was up 11.9% sequentially and 20.5% year-over-year. All major lines of business contributed to growth in the first quarter as private banking, institutional Wealth Management, corporate trust and Cavanal Hill Funds all delivered healthy sequential and year-over-year growth. In addition, money market fee waivers were only $445,000 in the quarter, down from $2.1 million in the same quarter last year and $1.4 million in the fourth quarter 2016. To give you some perspective, money market fee waivers were $12.5 million in 2015, which was the peak and $6.8 million in 2016. For the month of March 2017, we were down $63,000, so we believe this revenue headwind is for all intents and purposes, behind us at this point.
As expected, mortgage banking revenue was down 11.3% sequentially due to lower production volume and lower gain on sale margins. Refinancing volume fell to 44% of production in the first quarter due to higher overall interest rates.
Deposit service charges and fees were down 1.4% sequentially, but were up 2.2% year-over-year. As you can see on the chart on Slide 8, all of our major fee-generating businesses met or exceeded our mid-single-digit revenue growth target for the trailing 12 months ended March 31, 2017. In the overall growth rate for our total fees and commissions on a trailing 12-month basis was a healthy 5.8%.
Turning to Slide 9. Total operating expenses were down $21 million sequentially to $245 million despite layering in a full quarter of expenses from the Mobank acquisition. Mobank operating expenses were $2.9 million in the quarter compared to $1.2 million in the fourth quarter of '16. In addition, onetime cost associated with the Mobank operational integration took place over Presidents' Day weekend for $2 million, which was substantially lower than we expected.
Personnel expense was down almost $5 million. However, this was largely due to the nonrecurrence of the onetime charges associated with our cost actions in the fourth quarter. Excluding this item, personnel expenses were flat compared to the fourth quarter as lower compensation expense was offset by a full quarter of Mobank personnel expense and merit increases as well as a higher seasonal payroll tax.
Within other operating expenses, professional fees were down $4.4 million due to lower Mobank and mortgage-related outsourcing expenses. Deposit insurance expenses were down $2.4 million due to the improvements in credit quality and other risk factors. Mortgage banking costs were down $4.3 million from the fourth quarter primarily due to lower level of mortgage servicing right amortization.
Turning to the balance sheet on Slide 10. The available-for-sale securities portfolio was down $240 million in the first quarter. It is down $449 million from the same period last year. Period-end deposits were $22.6 billion at quarter end, down only slightly from the end of December. BOK Financial continues to be extremely well-capitalized as evidenced by the capital ratios on this slide. All capital ratios resumed growth in the first quarter after a $100 million capital deployment for the Mobank acquisition in the fourth quarter.
Turning to Slide 11. Our guidance assumptions for the balance of 2017 are as follows: Mid-single-digit loan growth for the full year; continued gradual decline in the securities portfolio with an overall reduction of about $700 million for the full year; stable to increasing net interest margin; low single-digit net interest revenue growth. We're reducing our loan loss provision expectations for the full year and are now forecasting $15 million to $20 million in provisions for the full year. This reflects an improved credit environment and lack of any areas of material stress in the nonenergy portfolio at present. On a rolling 12-month basis, we continue to expect low single-digit revenue growth in fees and commissions. We expect expenses to be flat to slightly down for the full year compared to 2016. We expect continued capital deployment through organic growth, acquisitions, dividends and limited stock buybacks.
