Thank you, Jim. Net total revenue preprovision and excluding the impacts of securities gains and noncore items showed modest growth from last quarter, overcoming typical season headwinds -- seasonal headwinds fourth quarter to first. Net interest income was up due to increases in loan yields across variable-rate loan portfolios. Fee income was a little softer on a core basis due to seasonal deposit trends, relatively slow loan-related fees and a more difficult mortgage banking environment.
The reported taxable equivalent margin was unchanged from last quarter, despite 17 basis points of headwinds on the comparison to last quarter. These changes were as follows: the change in the federal tax rate and its impact on effective yields from municipal securities had a negative impact of 10 basis points relative to the fourth quarter; approximately $450,000 of quarterly noninterest loan origination expense within the salaries and benefits caption in the fourth quarter last year instead negatively impacted the loan yield in the first quarter of 2018, 7 basis points of additional headwind. So obviously, it was a very strong quarter for margin and loan yields more specifically. Movements in LIBOR-based lending rates exceeded yields based on the federal fund rate movements during the quarter. This had a pronounced benefit for the first quarter of 2018 but will probably partially mitigate the impacts of future movements by the FOMC.
Pricing movement on the liability side of the balance sheet remains well controlled, with some pick up in time deposit competition during the quarter. We've seen a number of competitors, potentially looking to increase long-dated CDs in replacement of borrowings at this point, and some have gotten very aggressive.
We do have some maturities in the time deposit portfolio to deal with in the coming months, and it should result in modest increases in those funding costs.
We have new rates modestly higher in checking, money market and saving captions in response to recent rate hikes, with the goal of remaining within reasonable proximity to medium pricing in our markets.
We have yet to see anyone else move in these deposit captions, however. Overall, deposit betas have significantly outperformed our expectations over the last 12 months and over the last 3 months.
We continue to be very pleased with the level of deposit growth and the outlook for loan and margin trends going forward. The loan-to-deposit ratio, as Jim mentioned, improved to 81%. At this level, we have substantial flexibility both to continue to pursue the quality loan growth and to reengineer the balance sheet acquired from ABC to more closely align with our philosophy.
Looking forward, Jim mentioned the seasonal challenges on loan growth, though I believe the impact of the effect on growth should be moderated by stronger deposit trends and less of a need to remix earning assets.
Core margin trends continue to be biased higher. However, the degree of that expansion will be mitigated by the addition of the ABC balance sheet. It remains true that the bulk of deposit pricing pressure is isolated in larger balanced-deposit relationships. Our exposure in this caption is limited relative to competitors.
In the coming quarters, we will expect to bring back some larger deposit relationships that Old Second had previously moved off of our balance sheet due to excess liquidity recovering from the recession.
These are our customers that we have always and will continue to serve. The return of these balances are relatively more expensive than our existing all-in deposit cost of funds. However, they remain accretive to the margin overall relative to borrowing rates. They also provide substantially more funding to allow us to continue to pursue strategic loan growth opportunities in teams.
On the fee income side, wealth management and trust income continues to perform above-budgeted expectations. Mortgage banking experienced a decline in gain on sale margins during the quarter that was offset by an increase of interest-rate driven valuation adjustments on MSRs. Commercial swap fee income activity remained relatively low, commensurate with origination activity during the quarter.
Securities gains declined relative to last quarter, which is offset by a substantial increase in BOLI-related revenues, as Jim mentioned.
Expenses remain very well controlled. Not much really to talk about here, with typical first quarter increases in payroll-related tax increases. Our strong results afforded us the opportunity to increase the 401(k) match for our employees this quarter and offer salary increases at a rate above observed inflation for the first time in a long time.
Investments for future growth are largely baked into the run rate trends that you've been seeing from us. The effective tax rate for the current quarter, absent the impact of the BOLI benefit, was lower than we had previously expected.
Best guess going forward with the changes in statutory rates fully implemented and assuming the current makeup of the bond portfolio, which may change, we had considered a reduction of municipal securities, but we don't have a ton of duration on the balance sheet. And obviously, we have demonstrated a pretty significant amount of asset sensitivity at this point.
Probably, in the range of 24% to 25% effective for the remainder of 2018.
With that, I'll turn the call back over to Jim.
