The interest rate environment and optimizing our earning asset mix drove a 10.1 percent year-over-year increase in net interest income which, when combined with steady fee-based income, resulted in a 37.1 percent increase in income from continuing operations compared to the first quarter of 2017.”

Following the enactment of the Tax Cuts and Jobs Act, beginning in the first quarter of 2018, net interest margin is computed using net interest income adjusted to a fully taxable equivalent (“FTE”) basis assuming a statutory federal income tax rate of 21 percent and, where applicable, state income taxes; prior period net interest margins are computed using the then-statutory federal income tax rate of 35 percent and, where applicable, state income taxes.

Net interest income

• On a linked quarter basis, net interest income increased 1.1 percent while net interest margin declined two basis points. The calculation of the first quarter 2018 net interest margin was adversely impacted by lower tax equivalent income primarily on the company’s tax favored municipal bond investments, from the recently enacted tax legislation. The resulting impact to net interest margin from tax reform is approximately eleven basis points.

• Earning asset yields improved five basis points from the linked quarter driven by improved loan yields of 13 basis points to 4.53 percent, in part driven by favorable re-pricing driven by recent increase in short-term interest rates and volume changes within the loan portfolio. These asset yields were also affected by the impact of tax reform to tax equivalent income. The cost of interest-bearing liabilities increased ten basis points to 0.65 percent due to an increase of $136.8 million in federal fund borrowings, and an increase in interest rates paid on select interest-bearing deposit balances.

• On a year-over-year basis, the increase in net interest income was driven by a 6.9 percent or $726.4 million increase in average loans as well as higher average loan yields, which increased 44 basis points from one year ago, primarily driven by higher interest rates and mix changes, offset by the impacts of tax reform on tax equivalent income.

• For the first quarter 2018, average earning assets stood at $19.4 billion, which is an increase of 3.0 percent over the first quarter 2017.

Noninterest income

• First quarter 2018 noninterest income decreased $0.5 million, or 0.5 percent, on a linked quarter basis largely due to:

• a decrease of $0.9 million in trading and investment banking primarily due to lower trading volume and unfavorable fair value adjustments;

• a decrease of $0.6 million in other noninterest income primarily due to a decrease in company-owned life insurance income and a decrease in foreign exchange currency valuation;

• which were partially offset by an increase of $0.5 million in service charges on deposit accounts driven by the company’s healthcare services business; and

• an increase of $0.5 million in bankcard fee income primarily due to an increase in interchange income.

• Noninterest income in the first quarter of 2018 improved $2.6 million, or 2.5 percent, compared to the same quarter in 2017 primarily driven by:

• a $4.1 million increase in other noninterest income primarily due to increases in equity earnings on alternative investments and derivative income;

• a $0.4 million increase in wealth management revenue, a $0.3 million increase in fund servicing revenue, and a $0.7 million increase in corporate trust revenue all recorded in trust and securities processing;

• which were partially offset by a $3.4 million decrease in trading and investment banking due to a decrease of $1.8 million in bond trading fees, and a decline of $1.6 million in market adjustments from the company’s seed investments in certain Scout funds following the liquidation of such investments at the end of the second quarter of 2017.

Total noninterest expense	$	175,876	$	182,559	$	173,810	$	(6,683	)	$	2,066

• GAAP noninterest expense for the first quarter of 2018 was $175.9 million, which was a decrease of $6.7 million, or 3.7 percent from the linked quarter and an increase of $2.1 million, or 1.2 percent from the first quarter of 2017.

• On a non-GAAP basis, operating noninterest expense (as reconciled later in this release) was $173.9 million for the first quarter 2018, a decrease of $8.4 million, or 4.6 percent, compared to the linked quarter, and an increase of $0.6 million, or 0.3 percent, compared to the first quarter 2017.

• The linked quarter decrease in noninterest expense was driven by:

• a $2.2 million decrease in legal and consulting expense partially due to the delay in timing of future projects;

• a $1.9 million decrease in other noninterest expense driven by a $1.0 million contribution made to the UMB Financial Corporation Charitable Foundation in the fourth quarter 2017 and lower derivative expense and operational losses; and

• decreased marketing and business development expense related to timing of multiple projects and reduced regulatory fees due to lower regulatory assessments.

• The year-over-year increase in noninterest expense was driven by:

• a $4.3 million increase in salaries and employee benefits, largely due to a $2.2 million increase in salary and wage expense, a $1.5 million increase in severance and a $0.7 million increase in employee benefits driven by higher payroll taxes and 401(k) expense in 2018;

• $2.0 million increase in processing expenses related to investments for regulatory requirements, cyber security, and the ongoing modernization of the company’s core systems;

• which were partially offset by a $3.2 million decrease in other noninterest expense due to lower operational losses and losses on sales of other real estate owned in the current year; and decreased consulting expenses.

Income Taxes

• The company’s effective tax rate was 14.9 percent for the quarter ended March 31, 2018 compared to 22.9 percent for the same period in 2017. The decrease is primarily a result of the Tax Cuts and Jobs Act, which lowered the federal corporate income tax rate to 21 percent from 35 percent, effective on January 1, 2018.

Balance Sheet

• Average total assets for the first quarter 2018 were $20.7 billion, an increase of $23.3 million from the linked quarter, and up from $20.2 billion for the same period in 2017.

• Average securities available for sale decreased 4.2 percent as compared to the first quarter of 2017 driven by the ongoing reinvestment of cash flows from such securities to fund growth in the private placement bond and loan portfolios.

Non-GAAP Financial Information

In this release, we provide information about net operating income, operating earnings per share - diluted (operating EPS), operating return on average equity (operating ROE), operating return on average assets (operating ROA), operating noninterest expense, and operating efficiency ratio, all of which are non-GAAP financial measures. This information supplements the results that are reported according to generally accepted accounting principles in the United States (GAAP) and should not be viewed in isolation from, or as a substitute for, GAAP results. The differences between the non-GAAP financial measures—net operating income, operating EPS, operating ROE, operating ROA, operating noninterest expense, and operating efficiency ratio—and the nearest comparable GAAP financial measures are reconciled later in this release. The company believes that these non-GAAP financial measures and the reconciliations may be useful to investors because they adjust for acquisition- and severance-related items and divestiture costs that management does not believe reflect the company’s fundamental operating performance.

Net operating income for the relevant period is defined as GAAP net income, adjusted to reflect the impact of excluding expenses related to acquisitions and divestitures, severance expense, and the cumulative tax impact of these adjustments. The company believes that the financial impact of excluding severance expense will be immaterial in the near future. It is excluded from certain GAAP financial measures as it has an unusually large impact on the company’s financial statements.

Operating EPS (diluted) is calculated as earnings per share as reported, adjusted to reflect, on a per share basis, the impact of excluding the non-GAAP adjustments described above for the relevant period. Operating ROE is calculated as net operating income, divided by the company’s average total shareholders’ equity for the relevant period. Operating ROA is calculated as net operating income, divided by the company’s average assets for the relevant period. Operating noninterest expense for the relevant period is defined as GAAP noninterest expense, adjusted to reflect the pre-tax impact of non-GAAP adjustments described above. Operating efficiency ratio is calculated as the company’s operating noninterest expense, net of amortization of other intangibles, divided by the company’s total non-GAAP revenue (calculated as net interest income plus noninterest income, less gains on sales of securities available for sale, net).

The company has strategically aligned its operations into the following four reportable segments: Commercial Banking, Institutional Banking, Personal Banking, and Healthcare Services.

Previously, the company had the following two business segments: Bank and Asset Servicing. The company’s reportable segments include certain corporate overhead, technology and service costs that are allocated based on methodologies that are applied consistently between periods. For comparability purposes, amounts in all periods are based on methodologies in effect at March 31, 2018.
