Wintrust Financial Corporation Reports Record Second Quarter 2018 Net Income, an Increase of 38% Over Prior Year, and Year-to-Date Net Income of $171.6 million, an Increase of 39% Over Prior Year

ROSEMONT, Ill., July 17, 2018 (GLOBE NEWSWIRE) -- Wintrust Financial Corporation (“Wintrust” or “the Company”) (Nasdaq:WTFC) announced net income of $89.6 million or $1.53 per diluted common share for the second quarter of 2018 compared to net income of $82.0 million or $1.40 per diluted common share for the first quarter of 2018 and $64.9 million or $1.11 per diluted common share for the second quarter of 2017. The Company recorded net income of $171.6 million or $2.93 per diluted common share for the first six months of 2018 compared to net income of $123.3 million or $2.11 per diluted common share for the same period of 2017.

Highlights of the Second Quarter of 2018 *:

Total assets increased by $1.0 billion from the prior quarter and now total $29.5 billion.
Total deposits increased $1.1 billion from the prior quarter to $24.4 billion with non-interest bearing deposit accounts comprising 27% of total deposits.
Total loans increased by $548 million from the prior quarter.
Non-performing loans as a percentage of total loans decreased to 0.37% from 0.41% at the end of the prior quarter.
Allowance for loan losses as a percentage of total non-performing loans remained strong, increasing to 172%.
Net charge-offs decreased to $1.1 million, or two basis points of average total loans for the period.
Provision for credit losses totaled $5.0 million in the second quarter compared to $8.3 million in the prior quarter.
Net interest margin increased seven basis points and net interest income increased $13.1 million over the prior quarter.
Return on average assets increased to 1.26% from 1.20% in the first quarter. Return on average common equity increased to 11.94% from 11.29% in the first quarter.
Mortgage banking revenue increased to $39.8 million, up $8.9 million over the first quarter of 2018 due to higher originations during the traditional spring purchase market and a full quarter's impact from the iFreedom Direct Corporation DBA Veterans First Mortgage ("Veterans First") acquisition, offset by lower production margins and smaller positive fair market value adjustment to mortgage servicing rights.
Salaries and employee benefits increased $9.2 million from the most recent quarter due to a full quarter impact from the Veterans First acquisition as well as higher incentive compensation on variable pay based arrangements, commissions on mortgage originations and salaries due to the Company's growth.
Opened five new branches, including three locations in Illinois and two locations in Wisconsin.

* See "Supplemental Financial Measures/Ratios" on pages 11-12 for more information on non-GAAP measures.

Edward J. Wehmer, President and Chief Executive Officer, commented, "Wintrust reported net income of $89.6 million for the second quarter of 2018, the tenth consecutive quarter of record net income, and net income of $171.6 million for the first six months of 2018. These results were driven by strong loan and deposit growth and an increased net interest margin as we continue to benefit from rising interest rates. The second quarter of 2018 was also characterized by good credit quality metrics and increased mortgage banking revenue."

Mr. Wehmer continued, "We experienced strong loan growth within the commercial portfolio and premium finance receivables portfolios during the period. The commercial real estate portfolio remained relatively flat during the second quarter as elevated payoffs and paydowns offset new loan growth within the portfolio. We continue to take a measured approach in evaluating new commercial real estate loan opportunities due to supply and demand issues in the market place, pricing competition and easing of underwriting standards by some competitors. Overall, we grew our loan portfolio by $548 million during the second quarter of 2018. Our loan pipelines improved to the highest levels since the second quarter of 2017. The increased loan volume, continued improvement in net interest margin from rising interest rates and an additional day in the second quarter compared to the first quarter helped net interest income increase by $13.1 million in the second quarter of 2018. Deposit growth was strong in the second quarter of 2018 as deposits increased $1.1 billion and exceeded $24 billion as of the end of the quarter. Our deposit growth was primarily the result of growth in money market accounts and retail certificate of deposit accounts as active marketing campaigns began to take effect. Five branches added during the second quarter of 2018 contributed $134 million of retail deposit balances to this growth."

Commenting on credit quality, Mr. Wehmer noted, "During the second quarter of 2018, the Company continued its practice of addressing and resolving non-performing credits in a timely fashion. Net charge-offs totaled $1.1 million in the current quarter, decreasing $5.6 million from the first quarter of 2018. Additionally, net charge-offs as a percentage of average total loans decreased to two basis points from 13 basis points in the first quarter. Total non-performing assets decreased $7.5 million during the second quarter of 2018 resulting in non-performing assets as a percentage of total assets dropping from 0.44% to 0.40% during the period. Total non-performing loans decreased $6.4 million in the second quarter of 2018 and now total $83.3 million, or 0.37% of total loans. As a percentage of non-performing loans, the allowance for loan losses increased to 172% at the end of the second quarter of 2018 from 156% at the end of the first quarter of 2018. We believe that the Company's reserves remain appropriate."

Mr. Wehmer further commented, "Mortgage banking revenue in the second quarter of 2018 totaled $39.8 million, an increase of $8.9 million compared to the first quarter of 2018. Mortgage loan origination volumes in the second quarter of 2018 increased to $1.1 billion from $779 million in the first quarter of 2018 as a result of higher purchase originations during the traditional spring purchase market and a full quarter's impact from the Veterans First acquisition. The increase in mortgage banking revenue from higher originations was tempered by lower production margins and smaller positive fair market value adjustment to mortgage servicing rights as interest rates increased less during the second quarter of 2018 when compared to the first quarter of 2018. Home purchases activity represented 80% of the volume for the second quarter of 2018 compared to 73% in the first quarter of 2018. Our mortgage pipeline remains relatively strong. With respect to production margin, we anticipate that it will decline slightly in the third quarter with stabilization in future periods. We continue to focus on efficiencies in our delivery channels and operating costs in our mortgage banking area."

Turning to the future, Mr. Wehmer stated, "Our growth engine continued its momentum into the second quarter of 2018 and we expect that to continue for the second half of the year. Loan growth at the end of the second quarter of 2018 should add to this momentum as period-end loan balances exceeded the second quarter average balance by $327 million. Wintrust continues to take a steady and measured approach to achieving our main objectives of growing franchise value, increasing profitability, leveraging our expense infrastructure and continuing to increase shareholder value. As our growth engine continues its momentum, we expect continued organic growth while still focusing on expense control. We remain well-positioned for a rising interest rate environment in the future, which, coupled with this loan growth, should continue to grow net interest income. Evaluating strategic acquisitions and organic branch growth will also be a part of our overall growth strategy with the goal of becoming Chicago’s bank and Wisconsin’s bank. To that end, the Company opened five new branches in the second quarter of 2018 and will continue to evaluate future locations in our market area including four expected branch openings in the third quarter of 2018. Our opportunities for both internal growth and external growth remain consistently strong."

Net revenue is net interest income plus non-interest income.
See "Supplemental Financial Measures/Ratios" for additional information on this performance measure/ratio.
The net overhead ratio is calculated by netting total non-interest expense and total non-interest income, annualizing this amount, and dividing by that period's average total assets. A lower ratio indicates a higher degree of efficiency.
Period-end balance sheet percentage changes are annualized.

Certain returns, yields, performance ratios, or quarterly growth rates are “annualized” in this presentation to represent an annual time period. This is done for analytical purposes to better discern for decision-making purposes underlying performance trends when compared to full-year or year-over-year amounts. For example, a 5% growth rate for a quarter would represent an annualized 20% growth rate.

Potentially dilutive common shares can result from stock options, restricted stock unit awards, stock warrants, the Company’s convertible preferred stock and shares to be issued under the Employee Stock Purchase Plan and the Directors Deferred Fee and Stock Plan, being treated as if they had been either exercised or issued, computed by application of the treasury stock method. While potentially dilutive common shares are typically included in the computation of diluted earnings per share, potentially dilutive common shares are excluded from this computation in periods in which the effect would reduce the loss per share or increase the income per share. For diluted earnings per share, net income applicable to common shares can be affected by the conversion of the Company’s convertible preferred stock. Where the effect of this conversion would reduce the loss per share or increase the income per share for a period, net income applicable to common shares is not adjusted by the associated preferred dividends. On April 25, 2017, 2,073 shares of the Series C Preferred Stock were converted at the option of the respective holder into 51,244 shares of the Company's common stock, pursuant to the terms of the Series C Preferred Stock. On April 27, 2017, the Company caused a mandatory conversion of its outstanding 124,184 shares of Series C Preferred Stock into 3,069,828 shares of the Company's common stock at a conversion rate of 24.72 shares of common stock per share of Series C Preferred Stock. Cash was paid in lieu of fractional shares for an amount considered insignificant.

SUPPLEMENTAL FINANCIAL MEASURES/RATIOS

The accounting and reporting policies of Wintrust conform to generally accepted accounting principles (“GAAP”) in the United States and prevailing practices in the banking industry. However, certain non-GAAP performance measures and ratios are used by management to evaluate and measure the Company’s performance. These include taxable-equivalent net interest income (including its individual components), taxable-equivalent net interest margin (including its individual components), the taxable-equivalent efficiency ratio, tangible common equity ratio, tangible common book value per share and return on average tangible common equity. Management believes that these measures and ratios provide users of the Company’s financial information a more meaningful view of the performance of the Company's interest-earning assets and interest-bearing liabilities and of the Company’s operating efficiency. Other financial holding companies may define or calculate these measures and ratios differently.

Management reviews yields on certain asset categories and the net interest margin of the Company and its banking subsidiaries on a fully taxable-equivalent (“FTE”) basis. In this non-GAAP presentation, net interest income is adjusted to reflect tax-exempt interest income on an equivalent before-tax basis using tax rates effective as of the end of the period. This measure ensures comparability of net interest income arising from both taxable and tax-exempt sources. Net interest income on a FTE basis is also used in the calculation of the Company’s efficiency ratio. The efficiency ratio, which is calculated by dividing non-interest expense by total taxable-equivalent net revenue (less securities gains or losses), measures how much it costs to produce one dollar of revenue. Securities gains or losses are excluded from this calculation to better match revenue from daily operations to operational expenses. Management considers the tangible common equity ratio and tangible book value per common share as useful measurements of the Company’s equity. The Company references the return on average tangible common equity as a measurement of profitability.

The following table presents a reconciliation of certain non-GAAP performance measures and ratios used by the Company to evaluate and measure the Company’s performance to the most directly comparable GAAP financial measures for the last five quarters.

BUSINESS UNIT SUMMARY

Community Banking

Through its community banking unit, the Company provides banking and financial services primarily to individuals, small to mid-sized businesses, local governmental units and institutional clients residing primarily in the local areas the Company services. In the second quarter of 2018, revenue within this unit was primarily driven by increased net interest income due to a higher net interest margin, increased earning assets and one additional day in the second quarter. The net interest margin increased in the second quarter of 2018 compared to the first quarter of 2018 primarily as a result of higher yields on the commercial and commercial real estate loan portfolios (excluding lease loans) and the liquidity management assets portfolio, partially offset by higher rates on interest-bearing liabilities. Mortgage banking revenue increased by $8.9 million from $31.0 million for the first quarter of 2018 to $39.8 million for the second quarter of 2018. The higher revenue was primarily due to originations during the current period increasing to $1.1 billion from $778.9 million in the first quarter of 2018 as a result of typical seasonality in our primary markets and one full quarter's impact of Veterans First. Home purchases represented 80% of loan origination volume for the second quarter of 2018. The increase in revenue from higher originations was tempered by lower production margins and smaller positive fair market value adjustment to mortgage servicing rights as interest rates increased less during the second quarter of 2018 when compared to the first quarter of 2018. The Company's gross commercial and commercial real estate loan pipelines remain strong. Before the impact of scheduled payments and prepayments, at June 30, 2018, gross commercial and commercial real estate loan pipelines totaled $1.3 billion, or $847.4 million when adjusted for the probability of closing, compared to $1.1 billion, or $688.4 million when adjusted for the probability of closing, at March 31, 2018.

Specialty Finance

Through its specialty finance unit, the Company offers financing of insurance premiums for businesses and individuals, equipment financing through structured loans and lease products to customers in a variety of industries and accounts receivable financing, value-added, out-sourced administrative services, and other services. In the second quarter of 2018, the specialty finance unit experienced higher revenue as a result of increased volumes and higher yields within its insurance premium financing receivables portfolio. Originations of $2.1 billion during the second quarter of 2018 resulted in a $232.2 million increase in average balances. The increase in average balances along with higher yields on these loans resulted in a $5.3 million increase in interest income attributed to this portfolio. The Company's leasing business remained steady during the second quarter of 2018, with its portfolio of assets, including capital leases, loans and equipment on operating leases, totaling $1.0 billion at the end of the second quarter of 2018. Revenues from the Company's out-sourced administrative services business remained steady, totaling approximately $1.2 million in the second quarter of 2018 and $1.1 million in the first quarter of 2018.

Wealth Management

Through three separate subsidiaries within its wealth management unit, the Company offers a full range of wealth management services, including trust and investment services, asset management, securities brokerage services and 401(k) and retirement plan services. Wealth management revenue slightly decreased in the second quarter of 2018 to $22.6 million from $23.0 million in the first quarter of 2018. The decrease in revenue was primarily due to a decrease in brokerage fees due to a reduction in trading activity during the period. At June 30, 2018, the Company’s wealth management subsidiaries had approximately $24.6 billion of assets under administration, which includes $2.9 billion of assets owned by the Company and its subsidiary banks, representing a $299.0 million increase from the $24.3 billion of assets under administration at March 31, 2018. This increase in assets under administration was primarily driven by new customers and market appreciation. Starting in August, our brokerage services subsidiary, Wayne Hummer Investments, LLC, will be renamed to Wintrust Investments, LLC to better align with our Wintrust brand.

Includes interest-bearing deposits from banks, federal funds sold and securities purchased under resale agreements.
Investment securities includes investment securities classified as available-for-sale and held-to-maturity, and equity securities with readily determinable fair values. Equity securities without readily determinable fair values are included within other assets.
Interest income on tax-advantaged loans, trading securities and investment securities reflects a tax-equivalent adjustment based on the marginal federal corporate tax rate in effect as of the applicable period. The total adjustments for the three months ended June 30, 2018, March 31, 2018 and June 30, 2017 were $1.4 million, $1.2 million and $1.7 million, respectively.
Other earning assets include brokerage customer receivables and trading account securities.
Loans, net of unearned income, include non-accrual loans.
Interest rate spread is the difference between the yield earned on earning assets and the rate paid on interest-bearing liabilities.
Net free funds are the difference between total average earning assets and total average interest-bearing liabilities. The estimated contribution to net interest margin from net free funds is calculated using the rate paid for total interest-bearing liabilities.
See “Supplemental Financial Measures/Ratios” for additional information on this performance ratio.

For the second quarter of 2018, net interest income totaled $238.2 million, an increase of $13.1 million as compared to the first quarter of 2018 and an increase of $33.8 million as compared to the second quarter of 2017. Net interest margin was 3.61% (3.63% on a fully tax-equivalent basis) during the second quarter of 2018 compared to 3.54% (3.56% on a fully tax-equivalent basis) during the first quarter of 2018 and 3.41% (3.43% on a fully tax-equivalent basis) during the second quarter of 2017. The $13.1 million increase in net interest income in the second quarter of 2018 compared to the first quarter of 2018 was attributable to a $6.2 million increase from higher levels of earning assets, a $4.4 million increase from rising rates and a $2.5 million increase due to one more day in the quarter.

See “Supplemental Financial Measures/Ratios” for additional information on this performance ratio.

For the first six months of 2018 net interest income totaled $463.3 million, an increase of $66.3 million as compared to the first six months of 2017. Net interest margin was 3.58% (3.60% on a fully tax-equivalent basis) for the first six months of 2018 compared to 3.38% (3.41% on a fully tax-equivalent basis) for the first six months of 2017. The $66.3 million increase in net interest income in the first six months of 2018 compared to the same period of 2017 was attributable to a $39.0 million increase from higher levels of earning assets and a $27.3 million increase from rising rates.

Interest Rate Sensitivity

As an ongoing part of its financial strategy, the Company attempts to manage the impact of fluctuations in market interest rates on net interest income. Management measures its exposure to changes in interest rates by modeling many different interest rate scenarios.

The following interest rate scenarios display the percentage change in net interest income over a one-year time horizon assuming increases of 100 and 200 basis points and a decrease of 100 basis points. The Static Shock Scenario results incorporate actual cash flows and repricing characteristics for balance sheet instruments following an instantaneous, parallel change in market rates based upon a static (i.e. no growth or constant) balance sheet. Conversely, the Ramp Scenario results incorporate management’s projections of future volume and pricing of each of the product lines following a gradual, parallel change in market rates over twelve months. Actual results may differ from these simulated results due to timing, magnitude, and frequency of interest rate changes as well as changes in market conditions and management strategies. The interest rate sensitivity for both the Static Shock and Ramp Scenario at June 30, 2018, March 31, 2018 and June 30, 2017 is as follows:


Static Shock Scenario	+200 Basis Points		+100 Basis Points		-100 Basis Points
June 30, 2018	19.3	%	9.7	%	(10.7	)%
March 31, 2018	18.8	%	9.7	%	(11.6	)%
June 30, 2017	19.3	%	10.4	%	(13.5	)%

Ramp Scenario	+200 Basis Points		+100 Basis Points		-100 Basis Points
June 30, 2018	8.7	%	4.5	%	(4.4	)%
March 31, 2018	9.0	%	4.6	%	(4.8	)%
June 30, 2017	7.8	%	4.0	%	(4.6	)%

These results indicate that the Company has positioned its balance sheet to benefit from a rise in interest rates. This analysis also indicates that the Company would benefit to a greater magnitude should a rise in interest rates be significant (i.e., 200 basis points) and immediate (Static Shock Scenario).

As noted in the table on the previous page, the majority of the Company’s portfolio is tied to LIBOR indices which, as shown in the table above, do not mirror the same increases as the Prime rate when the Federal Reserve raises interest rates. Specifically, the Company has $7.5 billion of variable rate loans tied to one-month LIBOR and $4.4 billion of variable rate loans tied to twelve-month LIBOR. The above chart shows:

Notable contributions to the change in non-interest income are as follows:

The increase in wealth management revenue during the current period as compared to the same period of 2017 is primarily attributable to growth in assets under management along with market appreciation related to managed money accounts with fees based on assets under management. Wealth management revenue is comprised of the trust and asset management revenue of The Chicago Trust Company and Great Lakes Advisors and the brokerage commissions, managed money fees and insurance product commissions at Wayne Hummer Investments.

The increase in mortgage banking revenue in the current quarter as compared to the first quarter of 2018 resulted primarily from higher origination volumes as a result of typical seasonality in our primary markets and one full quarter's impact of Veterans First. Mortgage loans originated or purchased for sale totaled $1.1 billion in the second quarter of 2018 as compared to $778.9 million in the first quarter of 2018 and $1.1 billion in the second quarter of 2017. The increase from higher originations was tempered by lower production margins and smaller positive fair market value adjustment to mortgage servicing rights as interest rates increased less during the second quarter of 2018 when compared to the first quarter of 2018. Mortgage banking revenue includes revenue from activities related to originating, selling and servicing residential real estate loans for the secondary market. Mortgage revenue is also impacted by changes in the fair value of mortgage servicing rights as the Company does not hedge this change in fair value. The Company typically originates mortgage loans held-for-sale with associated mortgage servicing rights ("MSRs") retained or released. Additionally, through the acquisition of Veterans First, the Company acquired approximately $13.8 million of MSRs in the first quarter of 2018. The Company records MSRs at fair value on a recurring basis. The table below presents additional selected information regarding mortgage banking revenue for the respective periods.

Production revenue represents revenue earned from the origination and subsequent sale of mortgages, including gains on loans sold and fees from originations, processing and other related activities, and excludes servicing fees, changes in the fair value of servicing rights and changes to the mortgage recourse obligation.

The Company has typically written call options with terms of less than three months against certain U.S. Treasury and agency securities held in its portfolio for liquidity and other purposes. Management has entered into these transactions with the goal of economically hedging security positions and enhancing its overall return on its investment portfolio by using fees generated from these options to compensate for net interest margin compression. These option transactions are designed to mitigate overall interest rate risk and do not qualify as hedges pursuant to accounting guidance. Fees from covered call options decreased in the current quarter primarily as a result of selling call options against a smaller value of underlying securities resulting in lower premiums received by Company. There were no outstanding call option contracts at June 30, 2018, March 31, 2018 or June 30, 2017.

The decrease in operating lease income in the current quarter compared to the first quarter of 2018 is primarily related to a $1.1 million gain realized in the prior quarter from the sale of certain equipment held on operating leases.

Notable contributions to the change in non-interest expense are as follows:

Salaries and employee benefits expense increased in the current quarter compared to the first quarter of 2018 primarily as a result of higher salaries and commissions and incentive compensation. The increase in salaries is primarily due to additional salaries from the Veterans First acquisition as well as increases from merit-based salary increases for current employees effective in February and an increase of the minimum wage for eligible hourly employees effective in March. The increase in commissions and incentive compensation is the result of higher commissions due to increased production in mortgage banking and an increase in bonus and long-term performance-based incentive compensation recognized in the second quarter of 2018 due to higher earnings.

The increase in advertising and marketing expenses during the current quarter compared to the first quarter of 2018 and the second quarter of 2017 is primarily related to higher corporate sponsorship costs, which are typically higher in the spring and summer due to our marketing efforts with the Chicago Cubs and Chicago White Sox, as well as increased spending related to deposit generation and brand awareness to grow our loan and deposit portfolios. Marketing costs are incurred to promote the Company's brand, commercial banking capabilities, the Company's various products, to attract loans and deposits and to announce new branch openings as well as the expansion of the Company's non-bank businesses. The level of marketing expenditures depends on the timing of sponsorship programs and type of marketing programs utilized which are determined based on the market area, targeted audience, competition and various other factors.

The decrease in OREO expense in the current quarter compared to the first quarter of 2018 was primarily the result of negative valuation adjustments and realized losses on the sale of certain OREO properties recognized in the previous quarter from our continuing efforts to address and resolve non-performing assets in a timely fashion. OREO expenses include all costs associated with obtaining, maintaining and selling other real estate owned properties as well as valuation adjustments.

INCOME TAXES

The Company recorded income tax expense of $32.0 million in the second quarter of 2018 compared to $26.1 million in the first quarter of 2018 and $37.0 million in the second quarter of 2017. The effective tax rates were 26.33% in the second quarter of 2018, 24.14% in the first quarter of 2018 and 36.34% in the second quarter of 2017. During the six months ended June 30, 2018, the Company recorded income tax expense of $58.1 million (25.30% effective tax rate) compared to $66.7 million (35.11% effective tax rate) for the same period of 2017. The lower effective tax rates for the 2018 quarterly and year-to-date periods as compared to 2017 were primarily due to the reduction of the federal corporate income tax rate effective in 2018 as a result of the enactment of the Tax Cuts and Jobs Act on December 22, 2017. The Company recorded $712,000 of excess tax benefits in the second quarter of 2018 related to share-based compensation and $2.6 million in the first quarter of 2018, compared to $456,000 in the second quarter of 2017 and $3.4 million in the first quarter of 2017. Excess tax benefits are expected to be higher in the first quarter when the majority of the Company's share-based awards vest, and will fluctuate throughout the year based on the Company's stock price and timing of employee stock option exercises and vesting of other share-based awards.

Includes $742,000 of allowance for covered loan losses reclassified as a result of the termination of all existing loss share agreements with the FDIC during the fourth quarter of 2017.

The allowance for credit losses, excluding the allowance for covered loan losses, is comprised of the allowance for loan losses and the allowance for unfunded lending-related commitments. The allowance for loan losses is a reserve against loan amounts that are actually funded and outstanding while the allowance for unfunded lending-related commitments (separate liability account) relates to certain amounts that Wintrust is committed to lend but for which funds have not yet been disbursed. The provision for credit losses, excluding the provision for covered loan losses, may contain both a component related to funded loans (provision for loan losses) and a component related to lending-related commitments (provision for unfunded loan commitments and letters of credit).

Net charge-offs as a percentage of loans, excluding covered loans, for the second quarter of 2018 totaled two basis points on an annualized basis compared to 13 basis points on an annualized basis in the first quarter of 2018 and 10 basis points on an annualized basis in the second quarter of 2017. Net charge-offs totaled $1.1 million in the second quarter of 2018, a $5.6 million decrease from $6.7 million in the first quarter of 2018 and a $4.2 million decrease from $5.3 million in the second quarter of 2017. The decrease in the second quarter of 2018 compared to first quarter of 2018 is primarily the result of decreased net charge-offs within the commercial real estate, residential real estate and commercial insurance premium finance receivables portfolios. The decrease in the second quarter of 2018 compared to second quarter of 2017 is primarily the result of decreased net charge-offs within the commercial real estate and residential real estate portfolios. The provision for credit losses, excluding the provision for covered loan losses, totaled $5.0 million for the second quarter of 2018 compared to $8.3 million for the first quarter of 2018 and $9.0 million for the second quarter of 2017.

Management believes the allowance for credit losses is appropriate to provide for inherent losses in the portfolio. There can be no assurances, however, that future losses will not exceed the amounts provided for, thereby affecting future results of operations. The amount of future additions to the allowance for credit losses will be dependent upon management’s assessment of the appropriateness of the allowance based on its evaluation of economic conditions, changes in real estate values, interest rates, the regulatory environment, the level of past-due and non-performing loans and other factors.

The Company also provided a provision for covered loan losses on covered loans when applicable.

As part of the regular quarterly review performed by management to determine if the Company’s allowance for loan losses is appropriate, an analysis is prepared on the loan portfolio based upon a breakout of core loans and consumer, niche and purchased loans. A summary of the allowance for loan losses calculated for the loan components in both the core loan portfolio and the consumer, niche and purchased loan portfolio was shown on the preceding tables as of June 30, 2018 and March 31, 2018.

Purchased loans acquired in a business combination are recorded at estimated fair value on their purchase date. In accordance with accounting guidance, credit deterioration on purchased loans is recorded as a credit discount at the time of purchase instead of as an increase to the allowance for loan losses.

In addition to the $143.4 million of allowance for loan losses, there is $2.9 million of non-accretable credit discount on purchased loans reported in accordance with ASC 310-30 that is available to absorb credit losses.

Items Impacting Comparative Financial Results:

Acquisitions

On January 4, 2018, the Company acquired certain assets and assumed certain liabilities of the mortgage banking business of Veterans First, in a business combination. The Company also acquired mortgage servicing rights assets from Veterans First on approximately 10,000 loans, totaling an estimated $1.6 billion in unpaid principal balance. Veterans First is a consumer direct lender with three offices, operating two in Salt Lake City and one in San Diego, and originated in excess of $800 million in loans in 2017.

On February 14, 2017, the Company acquired certain assets and assumed certain liabilities of the mortgage banking business of American Homestead Mortgage, LLC ("AHM"), in a business combination. AHM is located in Montana's Flathead Valley and originated approximately $55 million of residential mortgage loans in 2016.

Termination of Loss Share Agreements

On October 16, 2017, the Company entered in agreements with the FDIC that terminated all existing loss share agreements with the FDIC. The loss share agreements were related to the Company’s acquisition of assets and assumption of liabilities of eight failed banks through FDIC assisted transactions in 2010, 2011 and 2012.

Under terms of the agreements, the Company made a net payment of $15.2 million to the FDIC as consideration for the early termination of the loss share agreements. The Company recorded a pre-tax gain of approximately $0.4 million in the fourth quarter of 2017 to write off the remaining loss share asset, relieve the claw-back liability and recognize the payment to the FDIC.

Approximately $0.2 million of the remaining net indemnification liabilities that were scheduled to be amortized against future earnings did not occur for the remainder of the fourth quarter of 2017. Additionally, $0.8 million, $0.8 million and $0.7 million each year in 2018, 2019 and 2020, respectively, of previously scheduled amortization will not occur.

The termination of the FDIC loss share agreements has no effect on yields of the loans that were previously covered under these agreements. Subsequent to this transaction, the Company is solely responsible for all future charge-offs, recoveries, gains, losses and expenses related to the previously covered assets as the FDIC will no longer share in those amounts.

Similarly, these statements are not guarantees of future performance and involve certain risks and uncertainties that are difficult to predict, which may include, but are not limited to, those listed below and the Risk Factors discussed under Item 1A of the Company’s 2017 Annual Report on Form 10-K and in any of the Company’s subsequent SEC filings. The Company intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and is including this statement for purposes of invoking these safe harbor provisions. Such forward-looking statements may be deemed to include, among other things, statements relating to the Company’s future financial performance, the performance of its loan portfolio, the expected amount of future credit reserves and charge-offs, delinquency trends, growth plans, regulatory developments, securities that the Company may offer from time to time, and management’s long-term performance goals, as well as statements relating to the anticipated effects on financial condition and results of operations from expected developments or events, the Company’s business and growth strategies, including future acquisitions of banks, specialty finance or wealth management businesses, internal growth and plans to form additional de novo banks or branch offices. Actual results could differ materially from those addressed in the forward-looking statements as a result of numerous factors, including the following:

negative economic conditions that adversely affect the economy, housing prices, the job market and other factors that may affect the Company’s liquidity and the performance of its loan portfolios, particularly in the markets in which it operates;
the extent of defaults and losses on the Company’s loan portfolio, which may require further increases in its allowance for credit losses;

changes in the level and volatility of interest rates, the capital markets and other market indices that may affect, among other things, the Company’s liquidity and the value of its assets and liabilities;

failure to identify and complete favorable acquisitions in the future or unexpected difficulties or developments related to the integration of the Company’s recent or future acquisitions;
unexpected difficulties and losses related to FDIC-assisted acquisitions;

ability of the Company to raise additional capital on acceptable terms when needed;

ability of the Company to use technology to provide products and services that will satisfy customer demands and create efficiencies in operations and to manage risks associated therewith;
failure or breaches of our security systems or infrastructure, or those of third parties;
security breaches, including denial of service attacks, hacking, social engineering attacks, malware intrusion or data corruption attempts and identity theft;
adverse effects on our information technology systems resulting from failures, human error or cyberattacks;
adverse effects of failures by our vendors to provide agreed upon services in the manner and at the cost agreed, particularly our information technology vendors;
increased costs as a result of protecting our customers from the impact of stolen debit card information;
accuracy and completeness of information the Company receives about customers and counterparties to make credit decisions;
ability of the Company to attract and retain senior management experienced in the banking and financial services industries;
environmental liability risk associated with lending activities;
the impact of any claims or legal actions to which the Company is subject, including any effect on our reputation;
losses incurred in connection with repurchases and indemnification payments related to mortgages and increases in reserves associated therewith;
the loss of customers as a result of technological changes allowing consumers to complete their financial transactions without the use of a bank;
the soundness of other financial institutions;
the expenses and delayed returns inherent in opening new branches and de novo banks;
examinations and challenges by tax authorities, and any unanticipated impact of the Tax Act;
changes in accounting standards, rules and interpretations such as the new CECL standard, and the impact on the Company’s financial statements;
the ability of the Company to receive dividends from its subsidiaries;
uncertainty about the future of LIBOR;
a decrease in the Company’s capital ratios, including as a result of declines in the value of its loan portfolios, or otherwise;
legislative or regulatory changes, particularly changes in regulation of financial services companies and/or the products and services offered by financial services companies;
a lowering of our credit rating;
changes in U.S. monetary policy and changes to the Federal Reserve’s balance sheet as a result of the end of its program of quantitative easing or otherwise;
restrictions upon our ability to market our products to consumers and limitations on our ability to profitably operate our mortgage business resulting from the Dodd-Frank Act;
increased costs of compliance, heightened regulatory capital requirements and other risks associated with changes in regulation and the regulatory environment;
the impact of heightened capital requirements;
increases in the Company’s FDIC insurance premiums, or the collection of special assessments by the FDIC;
delinquencies or fraud with respect to the Company’s premium finance business;
credit downgrades among commercial and life insurance providers that could negatively affect the value of collateral securing the Company’s premium finance loans;

Net revenue includes net interest income and non-interest income.
See “Supplemental Financial Measures/Ratios” for additional information on this performance measure/ratio.
The net overhead ratio is calculated by netting total non-interest expense and total non-interest income, annualizing this amount, and dividing by that period’s total average assets. A lower ratio indicates a higher degree of efficiency.
Capital ratios for current quarter-end are estimated.
The allowance for credit losses includes both the allowance for loan losses and the allowance for unfunded lending-related commitments, but excluding the allowance for covered loan losses.
Asset quality ratios exclude covered loans.
