Trustmark Corporation Announces 2017 Financial Results

JACKSON, Miss. – January 23, 2018 – Trustmark Corporation (NASDAQ:TRMK) reported net income  of $15.8 million in the fourth quarter of 2017, which represented diluted earnings per share of $0.23.   Included in the fourth quarter financial results were one-time charges resulting from the re-measurement of Trustmark’s net deferred tax assets due to the enactment of the Tax Cuts and Jobs Act of 2017 (Tax Reform Act) and the elimination of a deferred tax valuation allowance related to a prior merger, which collectively reduced net income by $17.0 million, or $0.25 per diluted share.  Adjusting for these items, net income in the fourth quarter totaled $32.7 million, representing diluted earnings per share of $0.48, an increase of 11.6% when compared to the same period in the prior year.

For the full year, Trustmark’s net income totaled $105.6 million, which represented diluted earnings per share of $1.56.  Excluding the one-time charges referenced above as well as the non-routine items related to the termination of Trustmark’s defined benefit pension plan ($10.9 million), the RB Bancorporation merger ($2.0 million) and the non-taxable proceeds related to life insurance ($4.9 million), diluted earnings per share were $1.92 in 2017.  Excluding non-routine items, diluted earnings per share were $1.70 in 2016.  

Trustmark’s Board of Directors declared a quarterly cash dividend of $0.23 per share payable March 15, 2018, to shareholders of record on March 1, 2018.  

2017 Highlights

• Loans held for investment increased $718.8 million, or 9.2%, during the year

• Credit quality remained solid as net charge-offs represented 11 basis points of average loans

• Deposits increased $521.5 million, or 5.2%

• Expanded presence in attractive Huntsville, Alabama MSA with the merger of RB Bancorporation

Our Mortgage Banking, Insurance Services and Wealth Management businesses posted another year of solid results.  We expanded our digital banking platform with the introduction of myTrustmark^® Business, which was well received by our customers.  We also made investments to enhance our customer contact center as well as to replace legacy-banking systems.  In addition, we continued to realign delivery channels in response to changing customer preferences and embraced opportunities to enhance efficiency and profitability.  Trustmark is well-positioned to meet the needs of our customers and create long-term value for our shareholders.”  

Balance Sheet Management

• Continued balance sheet optimization as maturing investment securities were replaced with organic loan growth

• Deposit costs remained well controlled

Loans held for investment totaled $8.6 billion at December 31, 2017, an increase of 1.9% from the prior quarter and 9.2% from the same period one year earlier.  Compared to the prior quarter, construction, land development and other land loans expanded $37.5 million, driven by growth in construction loans in Alabama. Other real estate secured loans increased by $35.8 million over the prior quarter, as growth in Mississippi and Alabama offset a minimal decrease in Tennessee.  Loans secured by 1-4 family residential properties grew $26.6 million quarter over quarter, principally due to growth in Mississippi and Alabama.  Other loans, which include loans to nonprofits and financial intermediaries, increased $25.4 million as growth in Mississippi, Texas and Tennessee more than offset declines in Alabama and Florida.              

Acquired loans totaled $261.5 million at December 31, 2017, down $22.2 million from the prior quarter.  Collectively, loans held for investment and acquired loans totaled $8.8 billion at December 31, 2017, up 1.6% from the prior quarter and 8.7% from the prior year.

Deposits totaled $10.6 billion at December 31, 2017, an increase of $345.8 million, or 3.4%, from the previous quarter and $521.5 million, or 5.2%, year-over-year.  Trustmark continues to maintain an attractive, low-cost deposit base with approximately 59% of deposits in checking accounts and a total cost of deposits of 0.28%.  The total cost of interest-bearing liabilities was 0.56% for the fourth quarter of 2017.  

Trustmark’s capital position remained solid, reflecting the consistent profitability of its diversified financial services businesses.  At December 31, 2017, Trustmark’s tangible equity to tangible assets ratio was 8.77%, while its total risk-based capital ratio was 13.10%.  Tangible book value per share was $17.35 at December 31, 2017, up 3.5% year-over-year.

Credit Quality

• Allowance for loan losses represented 320.8% of nonperforming loans, excluding specifically reviewed impaired loans

• Other real estate declined $5.1 million in the fourth quarter and $18.8 million year-over-year

Nonperforming loans totaled $67.6 million at December 31, 2017, down 2.5% from the prior quarter and up 37.3% year-over-year.  Other real estate totaled $43.2 million, reflecting a 10.6% linked-quarter decrease and a 30.3% year-over-year reduction.  Collectively, nonperforming assets totaled $110.8 million, reflecting a linked-quarter and year-over-year decrease of 5.8% and 0.4%, respectively.  

Allocation of Trustmark's $76.7 million allowance for loan losses represented 0.95% of commercial loans and 0.68% of consumer and home mortgage loans, resulting in an allowance to total loans held for investment of 0.90% at December 31, 2017.  This represents a level management considers commensurate with the inherent risk in the loan portfolio.  In aggregate, the allowance for both held for investment and acquired loan losses represented 0.92% of total loans held for investment and acquired loans.  

Net charge-offs totaled $9.3 million in the fourth quarter resulting from two impaired loans being written-down to collateral value.  One of the credits was impaired and reserved earlier in the year, while the other was an existing substandard credit that was impaired, provisioned and written-down during the fourth quarter.    

Unless noted otherwise, all of the above credit quality metrics exclude acquired loans.

Revenue Generation

• Net interest income (FTE) excluding acquired loans in 2017 totaled $402.9 million, up 7.2% from the prior year

• Noninterest income in 2017 totaled $184.7 million, up 6.2% from the prior year

Revenue in the fourth quarter totaled $148.0 million, down 0.3% from the prior quarter, reflecting in part a seasonal reduction in noninterest income.  Net interest income (FTE) in the fourth quarter totaled $109.1 million, resulting in a net interest margin of 3.48%.  Compared to the prior quarter, net interest income (FTE) increased $214 thousand primarily due to growth in interest income (FTE) from the held for sale and held for investment loan portfolios, which was offset in part by decreased yields on the securities portfolio.  During the fourth quarter of 2017, the yield on acquired loans totaled 9.27% and included $1.1 million in recoveries from the settlement of debt, which represented approximately 1.63% of the annualized total acquired loan yield. Excluding acquired loans, the net interest margin for the fourth quarter of 2017 remained stable compared to the third quarter of 2017, as increased yields on the loans held for investment and held for sale portfolio were offset by decreased yields on the securities portfolio and higher costs of interest-bearing deposits and other borrowings. Net interest income (FTE) in 2017 totaled $427.3 million, resulting in a net interest margin (FTE) of 3.48%; excluding acquired loans, the net interest margin (FTE) was 3.36%.        

Noninterest income totaled $44.0 million in the fourth quarter, down from the prior quarter primarily because of seasonally lower insurance commissions.  In the fourth quarter, bank card and other fees totaled $7.3 million, an increase of 1.6% from the prior quarter, while service charges on deposit accounts totaled $11.2 million, down 0.3% from the prior quarter.  Other income, net decreased $1.1 million linked quarter, primarily due to a decline in other miscellaneous income.  

Insurance revenue in the fourth quarter totaled $8.8 million, reflecting a seasonal decrease of 15.2% from the prior quarter and an increase of 4.2% compared to one year earlier.  Insurance revenue in 2017 totaled $38.2 million, up $1.4 million relative to the prior year.  The solid performance in 2017 reflects increased business development efforts and initiatives that supported enhanced productivity.  

Wealth management revenue totaled $7.7 million in the fourth quarter, an increase of 2.6% when compared to the prior quarter and 2.9% from levels one year earlier.  The year-over-year increase is primarily attributable to higher retail brokerage income.  Wealth management revenue in 2017 totaled $30.3 million, in-line with the prior year.  Trustmark remained focused on servicing clients and realigned processes to enhance productivity.    

Mortgage banking revenue in the fourth quarter totaled $6.3 million, up $1.9 million from the prior quarter.  The linked-quarter increase is primarily attributable to reduced net negative hedge ineffectiveness.  Mortgage loan production in the fourth quarter totaled $337.5 million, a seasonal decrease of 1.2% from the prior quarter and a 17.0% decrease year-over-year, primarily due to lower refinancing activity and rising interest rates.

In 2017, mortgage banking revenue totaled $29.9 million, up 6.0% from the prior year as a net positive mortgage servicing hedge ineffectiveness and increased mortgage servicing income were offset in part by lower secondary marketing gains.  Mortgage loan production totaled $1.4 billion in 2017, down 15.6% from the prior year primarily due to an extremely competitive third party origination environment.

Noninterest Expense and Taxes

• Core noninterest expense in 2017 totaled $399.5 million

• Continued realignment of retail delivery channel

• Trustmark estimates its annual effective income tax rate will decrease to approximately 12% to 14% beginning in 2018 primarily as a result of the Tax Cuts and Jobs Act of 2017

Core noninterest expense, which excludes other real estate expense ($666 thousand), intangible amortization ($1.5 million) and non-recurring items, totaled $100.8 million in the fourth quarter, an increase of $80 thousand on a comparable basis from the prior quarter and $3.6 million from the prior year.

Salaries and benefits totaled $59.8 million in the fourth quarter, up 1.6% linked quarter primarily due to increased expense related to incentive compensation programs.  Services and fees increased 1.9% from the prior quarter, reflecting higher spending on outside services and fees and advertising.  Other real estate expense totaled $666 thousand during the fourth quarter, representing a 22.9% decrease compared to the prior quarter.

Trustmark’s fourth quarter and year ended effective income tax rate equaled 61.4% and 31.6%, respectively.  Excluding the impact of the re-measurement of net deferred tax assets of $25.6 million related to the Tax Reform Act and the elimination of the deferred tax valuation allowance of $8.7 million during the fourth quarter, Trustmark’s fourth quarter and year ended effective tax rate would have been 19.9% and 20.6%, respectively.  Beginning in 2018, Trustmark estimates its annual effective income tax rate will be approximately 12% to 14% primarily as a result of the Tax Reform Act.  Trustmark’s effective income tax rate continues to be less than the statutory rate primarily due to various tax-exempt income items and its utilization of income tax credit programs.

Trustmark is committed to developing and maintaining relationships, supporting investments that promote profitable revenue growth and realigning retail delivery channels to support changing customer preferences. During 2017, Trustmark consolidated three branch offices and reallocated a portion of those resources to opening a new banking center.  Over the last five years, Trustmark has consolidated 38 branch offices with limited growth potential and established 10 banking centers in attractive growth markets.  In addition, Trustmark is piloting myTeller℠, an interactive video teller service provided through a centralized teller center which delivers most functions provided by traditional tellers.  The potential applications for this technology include deployment beyond the traditional branch network and expanded service hours, further enhancing customer convenience and improving operational efficiency. Trustmark also introduced myTrustmark^® Business, an enhanced and robust digital banking service for commercial customers to meet growing mobile and online demand. Trustmark remains committed to investments that promote profitable revenue growth as well as reengineering and efficiency opportunities that enhance long-term shareholder value.

Note 1 – Business Combinations

On April 7, 2017, Trustmark Corporation completed its merger with RB Bancorporation (Reliance), the holding company for Reliance Bank, which had seven offices serving the Huntsville, Alabama metropolitan service area (MSA).  Reliance Bank was merged into Trustmark National Bank simultaneously with the merger of Trustmark and RB Bancorporation. Under the terms of the Merger Agreement dated November 14, 2016, Trustmark paid $22.00 in cash for each share of Reliance common stock outstanding, which represented total consideration for Reliance common shareholders of approximately $23.7 million.

The merger with Reliance was consistent with Trustmark’s strategic plan to selectively expand the Trustmark franchise and enhance the Trustmark franchise in north Alabama.

This merger was accounted for in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 805, “Business Combinations.”  Accordingly, the assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the merger date.  The fair values of the assets acquired and liabilities assumed are subject to adjustment if additional information relative to the closing date fair values becomes available through the measurement period, which is not to exceed one year from the merger date of April 7, 2017.

The statement of assets purchased and liabilities assumed in the Reliance merger is presented below at their estimated fair values as of the merger date of April 7, 2017 ($ in thousands):

Assets:
Cash and due from banks	$	5,013
Federal funds sold and securities purchased under reverse repurchase agreements		6,900
Securities		54,843
Acquired loans		117,447
Premises and equipment, net		3,700
Identifiable intangible assets		1,850
Other real estate		475
Other assets		6,037
Total assets		196,265
Liabilities:
Deposits		166,158
Other borrowings		17,469
Other liabilities		1,322
Total liabilities		184,949
Net identifiable assets acquired at fair value		11,316
Goodwill		13,472
Net assets acquired at fair value	$	24,788

The excess of the consideration paid over the estimated fair value of the net assets acquired was $13.5 million, which was recorded as goodwill under FASB ASC Topic 805.  The identifiable intangible assets acquired represent the core deposit intangible at fair value at the merger date.  The core deposit intangible is being amortized on an accelerated basis over the estimated useful life, currently expected to be approximately ten years.

Loans acquired from Reliance were evaluated under a fair value process.  Loans with evidence of deterioration in credit quality and for which it was probable at acquisition that Trustmark would not be able to collect all contractually required payments are referred to as acquired impaired loans and accounted for in accordance with FASB ASC Topic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.”  

The operations of Reliance are included in Trustmark’s operating results from April 7, 2017 and did not have a material impact on Trustmark’s results of operations.  During the second quarter of 2017, Trustmark included non-routine merger transaction expenses in other noninterest expense totaling $3.2 million (change in control expense of $1.3 million; professional fees, contract termination and other expenses of $1.9 million).

At December 31, 2017, the net unamortized, unrealized loss included in accumulated other comprehensive loss in the accompanying balance sheet for securities held to maturity previously transferred from securities available for sale totaled approximately $19.5 million ($12.0 million, net of tax).

Management continues to focus on asset quality as one of the strategic goals of the securities portfolio, which is evidenced by the investment of approximately 96% of the portfolio in GSE-backed obligations and other Aaa rated securities as determined by Moody’s. None of the securities owned by Trustmark are collateralized by assets which are considered sub-prime. Furthermore, outside of stock ownership in the Federal Home Loan Bank of Dallas, Federal Home Loan Bank of Atlanta and Federal Reserve Bank, Trustmark does not hold any other equity investment in a GSE.

(1) Trustmark revised the presentation of acquired loans by eliminating the segmentation of acquired noncovered loans and acquired covered loans due to the significantly reduced size of the acquired covered loan portfolio.

During the first quarter of 2017, Trustmark transferred the remaining balance of the acquired loans not accounted for under FASB ASC Topic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality” to LHFI due to the discount on these loans being fully amortized.  The balance of these transferred loans totaled $36.7 million.

Reflected in the table above are yields on earning assets and liabilities, along with the net interest margin which equals reported net interest income-FTE, annualized, as a percent of average earning assets. In addition, the table includes net interest margin excluding acquired loans, which equals reported net interest income-FTE excluding interest income on acquired loans, annualized, as a percent of average earning assets excluding average acquired loans.  

During the fourth quarter of 2017, the yield on acquired loans totaled 9.27% and included $1.1 million in recoveries from the settlement of debt, which represented approximately 1.63% of the annualized total acquired loan yield.  Excluding acquired loans, the net interest margin for the fourth quarter of 2017 remained relatively flat compared to the third quarter of 2017, as increased yields on the loans held for investment and held for sale portfolio were offset by decreased yields on the securities portfolio and higher costs of interest-bearing deposits and other borrowings.    

Note 5 – Mortgage Banking

Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that offsets the changes in fair value of mortgage servicing rights (MSR) attributable to interest rates.  These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting under generally accepted accounting principles (GAAP).  Changes in the fair value of these exchange-traded derivative instruments, including administrative costs, are recorded in noninterest income in mortgage banking, net and are offset by the changes in the fair value of the MSR.  The MSR fair value represents the present value of future cash flows, which among other things includes decay and the effect of changes in interest rates.  Ineffectiveness of hedging the MSR fair value is measured by comparing the change in value of hedge instruments to the change in the fair value of the MSR asset attributable to changes in interest rates and other market driven changes in valuation inputs and assumptions.  

The following table illustrates the components of mortgage banking revenues included in noninterest income in the accompanying income statements:

Note 6 – Salaries and Employee Benefit Plans

Early Retirement Program

During the second quarter of 2016, Trustmark announced a voluntary early retirement program (ERP) for associates age 60 and above with five or more years of service.  The cost of this program is reflected in a one-time, pre-tax charge of approximately $9.3 million (salaries and employee benefits expense of $9.1 million and other miscellaneous expense of $230 thousand), or $0.085 per basic share net of tax, in Trustmark’s second quarter 2016 earnings.  As a result of the ERP, during the third and fourth quarters of 2016, Trustmark incurred additional expense of $236 thousand and $268 thousand, respectively, which primarily resulted from additional settlements from pension lump sum elections.

Defined Benefit Pension Plan

Trustmark maintained a noncontributory tax-qualified defined benefit pension plan (Trustmark Capital Accumulation Plan, the “Plan”), in which substantially all associates who began employment prior to 2007 participated.  The Plan provided for retirement benefits based on the length of credited service and final average compensation, as defined in the Plan, which vested upon three years of service.  Benefit accruals under the plan were frozen in 2009, with the exception of certain associates covered through plans obtained in acquisitions that were subsequently merged into the Plan.  As previously reported, on July 26, 2016, the Board of Directors of Trustmark authorized the termination of the Plan, effective as of December 31, 2016. To satisfy commitments made by Trustmark to associates (collectively, the “Continuing Associates”) covered through acquired plans that were merged into the Plan, the Board also approved the spin-off of the portion of the Plan associated with the accrued benefits of the Continuing Associates into a new plan titled the Trustmark Corporation Pension Plan for Certain Employees of Acquired Financial Institutions (the “Spin-Off Plan”), effective as of December 31, 2016, immediately prior to the termination of the Plan.  In order to terminate the Plan, in accordance with Internal Revenue Service and Pension Benefit Guaranty Corporation requirements, Trustmark was required to fully fund the Plan on a termination basis and contributed the additional assets necessary to do so. The final distributions were made from current plan assets and a one-time pension settlement expense of $17.6 million was recognized when paid by Trustmark during the second quarter of 2017.  After the distribution of Plan assets during the second quarter of 2017, Trustmark estimates that the annual pension expense will be reduced by $3.0 million to $4.0 million.

Trustmark invests in partnerships that provide income tax credits on a Federal and/or State basis (i.e., new market tax credits, low income housing tax credits and historical tax credits). The income tax credits related to these partnerships are utilized as specifically allowed by income tax law and are recorded as a reduction in income tax expense.

Trustmark received nontaxable proceeds of $1.7 million and $2.7 million related to bank-owned life insurance during the fourth and third quarters of 2017, respectively, and $4.9 million related to life insurance acquired as part of a previous acquisition during the second quarter of 2017, which were recorded in other miscellaneous income in the table above.

During 2013, a deferred tax valuation allowance was created as a result of Trustmark’s merger with BancTrust Financial Group, Inc. and was established to reduce deferred tax assets to the amount that was more likely than not to be realized in future years.  Trustmark has continually evaluated this allowance since inception and, based on the weight of the available evidence, has determined that the deferred tax assets will not be subject to the limitations on the deductibility of built-in losses (Internal Revenue Service Code, Section 382) in future years.  Therefore, during the fourth quarter of 2017, the valuation allowance was eliminated creating a decrease in deferred income tax expense of $8.7 million.

Following the recent enactment of the Tax Cuts and Jobs Act of 2017 (Tax Reform Act) which resulted in the reduction of the corporate federal income tax rate, Trustmark re-measured its net deferred tax assets and recorded an increase in deferred income tax expense of $25.6 million during the fourth quarter of 2017.  In addition, Trustmark estimates its effective income tax rate to decrease from approximately 21% (excluding the elimination of the deferred tax valuation allowance and the re-measurement of net deferred tax assets) in 2017 to approximately 12% to 14% beginning in 2018, primarily as a result of the Tax Reform Act.  Trustmark’s effective tax rate continues to be less than the statutory rate primarily due to various tax-exempt income items and its utilization of income tax credit programs.

Note 9 – Non-GAAP Financial Measures

In addition to capital ratios defined by U.S. generally accepted accounting principles (GAAP) and banking regulators, Trustmark utilizes various tangible common equity measures when evaluating capital utilization and adequacy.  Tangible common equity, as defined by Trustmark, represents common equity less goodwill and identifiable intangible assets.

Trustmark believes these measures are important because they reflect the level of capital available to withstand unexpected market conditions.  Additionally, presentation of these measures allows readers to compare certain aspects of Trustmark’s capitalization to other organizations.  These ratios differ from capital measures defined by banking regulators principally in that the numerator excludes shareholders’ equity associated with preferred securities, the nature and extent of which varies across organizations.  In Management’s experience, many stock analysts use tangible common equity measures in conjunction with more traditional bank capital ratios to compare capital adequacy of banking organizations with significant amounts of goodwill or other tangible assets, typically stemming from the use of the purchase accounting method in accounting for mergers and acquisitions.

These calculations are intended to complement the capital ratios defined by GAAP and banking regulators.  Because GAAP does not include these capital ratio measures, Trustmark believes there are no comparable GAAP financial measures to these tangible common equity ratios.  Despite the importance of these measures to Trustmark, there are no standardized definitions for them and, as a result, Trustmark’s calculations may not be comparable with other organizations.  Also there may be limits in the usefulness of these measures to investors.  As a result, Trustmark encourages readers to consider its consolidated financial statements in their entirety and not to rely on any single financial measure.  The following table reconciles Trustmark’s calculation of these measures to amounts reported under GAAP.

Note 9 – Non-GAAP Financial Measures (continued)

Trustmark discloses certain non-GAAP financial measures, including net income adjusted for significant non-routine transactions, because Management uses these measures for business planning purposes, including to manage Trustmark’s business against internal projected results of operations and to measure Trustmark’s performance.  Trustmark views net income adjusted for significant non-routine transactions as a measure of our core operating business, which excludes the impact of the items detailed below, as these items are generally not operational in nature.  This non-GAAP measure also provides another basis for comparing period-to-period results as presented in the accompanying selected financial data table and the audited consolidated financial statements by excluding potential differences caused by non-operational and unusual or non-recurring items.  Readers are cautioned that these adjustments are not permitted under GAAP.  Trustmark encourages readers to consider its consolidated financial statements and the notes related thereto in their entirety, and not to rely on any single financial measure.

The following table presents adjustments to net income and select financial ratios as reported in accordance with GAAP resulting from significant non-routine items occurring during the periods presented ($ in thousands, except per share data):
