ROSEMONT, Ill., Oct. 17, 2018 (GLOBE NEWSWIRE) -- Wintrust Financial Corporation (“Wintrust” or “the Company”) (Nasdaq: WTFC) announced net income of $91.9 million or $1.57 per diluted common share for the third quarter of 2018 compared to net income of $89.6 million or $1.53 per diluted common share for the second quarter of 2018 and $65.6 million or $1.12 per diluted common share for the third quarter of 2017. The Company recorded net income of $263.5 million or $4.50 per diluted common share for the first nine months of 2018 compared to net income of $188.9 million or $3.23 per diluted common share for the same period of 2017.

Highlights of the Third Quarter of 2018 *:

• Total loans increased by $513 million from the prior quarter, which included $151 million of loans acquired in relation to the previously-announced acquisition of Delaware Place Bank and its parent ("Delaware Place Bank") completed in early August.
• Total assets now exceed $30 billion, increasing $678 million from the prior quarter. Asset growth included $280 million of assets acquired in relation to the acquisition of Delaware Place Bank.
• Total deposits increased by $551 million from the prior quarter to $24.9 billion. This increase included $213 million from the acquisition of Delaware Place Bank.
• Net interest income increased by $9.4 million from the prior quarter as a result of earning assets growth and one additional day in the quarter, partially offset by a two basis point reduction in net interest margin. The net interest margin decreased during the quarter primarily as a result of higher deposit costs from retail certificate of deposit and money market accounts, partially offset by increased yields on our loan portfolio.
• Mortgage banking revenue increased to $42.0 million, up $2.2 million over the second quarter of 2018 primarily due to increased revenue from loans originated and sold during the third quarter, offset by lower production margins and a smaller positive fair market value adjustment to mortgage servicing rights.
• Professional fees were impacted by certain consulting agreements paid in relation to the acquisition of Delaware Place Bank totaling $2.1 million. Approximately $147,000 of additional payments will be made in the fourth quarter related to these agreements. Other Delaware Place Bank related expenses in the third quarter were $64,000 of severance and $130,000 of system conversion-related costs.
• Non-performing loans increased to $127.2 million. The increase from the prior quarter was primarily the result of four credit relationships totaling $46.6 million becoming non-performing during the third quarter.
• Provision for credit losses totaled $11.0 million in the third quarter, increasing $6.0 million from the prior quarter. This increase was driven by $7.5 million of specific reserves on the four non-performing credit relationships noted above.
• Opened three new branches, including two locations in Wisconsin and one location in Illinois. These locations along with the one location acquired from Delaware Place Bank in the Gold Coast/Streeterville neighborhood of Chicago, Illinois increase our total branches to 166 locations.

Edward J. Wehmer, President and Chief Executive Officer, commented, "Wintrust reported net income of $91.9 million for the third quarter of 2018, the eleventh consecutive quarter of record net income, and net income of $263.5 million for the first nine months of 2018. These results reflected the steady strength of our internal growth engine at Wintrust as we grew assets by $678 million compared to the prior quarter.  The third quarter of 2018 was also characterized by strong deposit growth, increased deposit costs, higher levels of liquidity and the acquisition of Delaware Place Bank."

Mr. Wehmer continued, "We grew our loan portfolio by $513 million during the third quarter, which included $151 million of loans acquired in relation to the acquisition of Delaware Place Bank. We experienced strong loan growth among our various loan categories during the period, including our commercial, commercial real estate and premium financing portfolios. We continue to take a measured approach in evaluating new loan opportunities. Our strategy to reduce our average loan to average deposit ratio below 90% continued in the third quarter. As part of this strategy, liquidity was accumulated and held to be invested at times that would yield appropriate spreads.  During most of the third quarter, yields were not in an acceptable range to allow immediate significant deployment of short-term liquidity into longer-term, higher yielding securities.  Thus, levels of liquidity were higher in the third quarter compared to the prior quarter.  Had the excess interest-bearing cash accumulated during the quarter been invested in the longer-term, higher yielding securities, the net interest margin would have been positively impacted by approximately 2 basis points, negating the reported net interest margin decline during the current quarter. Despite the reduction in net interest margin, net interest income increased by $9.4 million in the third quarter of 2018 primarily as a result of growth in outstanding loans and one additional day in the third quarter compared to the second quarter. Our loan pipelines remain consistently strong. Total deposits increased $551 million over the second quarter of 2018 to $24.9 billion as strong deposit growth continued in the third quarter of 2018. This increase in deposits included $213 million from the acquisition of Delaware Place Bank. Organic deposit growth was primarily related to money market accounts and certificate of deposit accounts as active marketing campaigns continued into the third quarter."

Commenting on credit quality, Mr. Wehmer noted, "The Company continued its practice of addressing and resolving non-performing credits in a timely fashion in the third quarter of 2018. Non-performing loans totaled $127.2 million, or 0.55% of total loans, an increase of $43.9 million compared to the most recent quarter. This increase during the third quarter of 2018 was primarily the result of four relationships totaling $46.6 million within the commercial loan portfolio becoming non-performing during the period. These four credit relationships are well reserved at the end of the quarter and are expected to be substantially resolved by the end of the first quarter of 2019. We believe these specific relationships are not characteristic of the entire portfolio and do not represent a trend within our overall loan portfolio. As a result of the increase in non-performing loans, the allowance for loan losses as a percentage of non-performing loans decreased to 118% at the end of the third quarter from 172% at the end of the second quarter. Net charge-offs totaled $4.7 million in the current quarter, increasing $3.6 million from the second quarter of 2018. Additionally, net charge-offs as a percentage of average total loans increased to eight basis points from two basis points in the second quarter. The increase in net charge-offs during the third quarter was primarily the result of higher recoveries within the commercial real estate and residential real estate portfolios during the second quarter. The specific reserves recognized on the four noted non-performing credit relationships, net charge-offs during the period and additional reserves established for loan growth during the period primarily drove the $11.0 million of provision for credit losses recognized in the third quarter of 2018. We believe that the Company's reserves remain appropriate."

Mr. Wehmer further commented, "Mortgage banking revenue in the third quarter of 2018 totaled $42.0 million, an increase of $2.2 million compared to the second quarter of 2018. Mortgage loan origination volumes in the third quarter of 2018 increased slightly to $1.2 billion from $1.1 billion in the second quarter of 2018. The increase in mortgage banking revenue was primarily due to increased revenue from loans originated and sold during the third quarter, tempered by smaller positive fair market value adjustment to mortgage servicing rights and reduction of production margin. We continue to focus on efficiencies in our delivery channels and operating costs in our mortgage banking area. Home purchase activity represented 76% of the volume for the third quarter of 2018 compared to 80% in the second quarter of 2018. We expect lower origination volumes in the fourth quarter due to normal seasonality and higher mortgage rates."

Turning to the future, Mr. Wehmer stated, "As our growth engine continues its momentum towards the end of 2018, we expect continued organic growth in all areas of our business. Loan growth at the end of the third quarter should add to momentum into the fourth quarter as period-end loan balances exceeded the third quarter average balances by approximately $301 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. We remain well-positioned for a rising interest rate environment in the future, which, coupled with this loan growth and investing our liquidity, 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, in addition to the location acquired through the Delaware Place Bank, the Company opened three new branches in the third quarter of 2018 and will continue to evaluate future locations in our market area. Our opportunities for both internal growth and external growth remain consistently strong."

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 third quarter of 2018, revenue within this unit was primarily driven by increased net interest income due to increased earning assets and one additional day in the third quarter. The net interest margin decreased in the third quarter of 2018 compared to the second quarter of 2018 primarily as a result of higher deposit costs, partially offset by higher yields within the loan portfolio. Mortgage banking revenue increased by $2.2 million from $39.8 million for the second quarter of 2018 to $42.0 million for the third quarter of 2018. The higher revenue was primarily due to increased revenue from loans originated and sold during the third quarter, offset by lower production margins and smaller positive fair market value adjustment to mortgage servicing rights. Originations during the current period increased slightly to $1.2 billion from $1.1 billion in the second quarter of 2018. Home purchases represented 76% of loan origination volume for the third 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 September 30, 2018, gross commercial and commercial real estate loan pipelines totaled $1.1 billion, or $693.5 million when adjusted for the probability of closing, compared to $1.3 billion, or $847.4 million when adjusted for the probability of closing, at June 30, 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 third 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 $1.9 billion during the third quarter of 2018 resulted in a $345.2 million increase in average balances. The increase in average balances along with higher yields on these loans resulted in an $8.7 million increase in interest income attributed to this portfolio. The Company's leasing business showed steady growth during the third quarter of 2018, with its portfolio of assets, including capital leases, loans and equipment on operating leases, totaling $1.1 billion at the end of the third quarter of 2018. Revenues from the Company's out-sourced administrative services business remained steady, totaling approximately $1.1 million in the third quarter of 2018 and $1.2 million in the second 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 remained flat in the third quarter of 2018 compared to the second quarter of 2018, totaling $22.6 million in the current period. At September 30, 2018, the Company’s wealth management subsidiaries had approximately $26.0 billion of assets under administration, which includes $3.2 billion of assets owned by the Company and its subsidiary banks, representing a $1.4 billion increase from the $24.6 billion of assets under administration at June 30, 2018. In August, our brokerage services subsidiary, Wayne Hummer Investments, LLC, was renamed to Wintrust Investments, LLC to better align with our Wintrust brand.

(1) Includes interest-bearing deposits from banks, federal funds sold and securities purchased under resale agreements.
(2) 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.
(3) 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 September 30, 2018, June 30, 2018 and September 30, 2017 were $1.5 million, $1.4 million and $2.0 million, respectively.
(4) Other earning assets include brokerage customer receivables and trading account securities.
(5) Loans, net of unearned income, include non-accrual loans.
(6) Interest rate spread is the difference between the yield earned on earning assets and the rate paid on interest-bearing liabilities.
(7) 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.
(8) See “Supplemental Financial Measures/Ratios” for additional information on this performance ratio.

For the third quarter of 2018, net interest income totaled $247.6 million, an increase of $9.4 million as compared to the second quarter of 2018 and an increase of $31.6 million as compared to the third quarter of 2017. Net interest margin was 3.59% (3.61% on a fully tax-equivalent basis) during the third quarter of 2018 compared to 3.61% (3.63% on a fully tax-equivalent basis) during the second quarter of 2018 and 3.43% (3.46% on a fully tax-equivalent basis) during the third quarter of 2017. The $9.4 million increase in net interest income in the third quarter of 2018 compared to the second quarter of 2018 was attributable to a $9.1 million increase from higher levels of earning assets and a $2.6 million increase due to one more day in the quarter, partially offset by a $2.3 million decrease due to a lower net interest margin during the period.

For the first nine months of 2018 net interest income totaled $710.8 million, an increase of $97.8 million as compared to the first nine months of 2017. Net interest margin was 3.58% (3.60% on a fully tax-equivalent basis) for the first nine months of 2018 compared to 3.40% (3.43% on a fully tax-equivalent basis) for the first nine months of 2017. The $97.8 million increase in net interest income in the first nine months of 2018 compared to the same period of 2017 was attributable to a $60.1 million increase from higher levels of earning assets and a $37.8 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 September 30, 2018, June 30, 2018 and September 30, 2017 is as follows:

Static Shock Scenario		+200 Basis  Points			+100  Basis  Points			-100 Basis  Points
September 30, 2018		18.1	%		9.1	%		(10.0	)%
June 30, 2018		19.3	%		9.7	%		(10.7	)%
September 30, 2017		19.5	%		9.8	%		(12.9	)%

Ramp Scenario	+200 Basis Points			+100 Basis Points			-100 Basis Points
September 30, 2018	8.5	%		4.3	%		(4.2	)%
June 30, 2018	8.7	%		4.5	%		(4.4	)%
September 30, 2017	9.0	%		4.6	%		(5.3	)%

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).

NM - Not meaningful

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

The increase in mortgage banking revenue in the current quarter as compared to the second quarter of 2018 resulted primarily from increased revenue from loans originated and sold, offset by lower production margins and smaller positive fair market value adjustment to mortgage servicing rights. Mortgage loans originated or purchased for sale totaled $1.2 billion in the third quarter of 2018 as compared to $1.1 billion in the second quarter of 2018 and $956.0 million in the third quarter of 2017. 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.

(1) 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. There were no outstanding call option contracts at September 30, 2018, June 30, 2018 or September 30, 2017.

The increase in miscellaneous non-interest income in the current quarter as compared to the second quarter of 2018 is primarily due to higher card-based fees and higher income from investments in partnerships.

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 second quarter of 2018 primarily as a result of higher salaries and benefits. The increase in salaries is primarily due to additional salaries as the Company grows as well as the acquisition of Delaware Place Bank. The increase in employee benefits expense was primarily the result of higher employee insurance costs.

The increase in professional fees during the third quarter of 2018 compared to the second quarter of 2018 related primarily to higher consulting fees. The increase in consulting fees was driven by certain consulting agreements paid in relation to the acquisition of Delaware Place Bank totaling $2.1 million. Approximately $147,000 of additional payments will be made in the fourth quarter related to these agreements. Professional fees include legal, audit and tax fees, external loan review costs, consulting and regulatory exam assessments.

INCOME TAXES

The Company recorded income tax expense of $30.9 million in the third quarter of 2018 compared to $32.0 million in the second quarter of 2018 and $38.6 million in the third quarter of 2017. The effective tax rates were 25.13% in the third quarter of 2018, 26.33% in the second quarter of 2018 and 37.05% in the third quarter of 2017. During the nine months ended September 30, 2018, the Company recorded income tax expense of $89.0 million (25.24% effective tax rate) compared to $105.3 million (35.79% 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 $370,000 of excess tax benefits in the third quarter of 2018 related to share-based compensation and $712,000 in the second quarter of 2018, compared to $1.1 million in the third 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.

(1) 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 third quarter of 2018 totaled eight basis points on an annualized basis compared to two basis points on an annualized basis in the second quarter of 2018 and eight basis points on an annualized basis in the third quarter of 2017.  Net charge-offs totaled $4.7 million in the third quarter of 2018, a $3.6 million increase from $1.1 million in the second quarter of 2018 and a slight increase from $4.5 million in the third quarter of 2017. The increase in net charge-offs in the third quarter of 2018 compared to second quarter of 2018 is primarily the result of higher recoveries within the commercial real estate and residential real estate portfolios in the second quarter of 2018. The provision for credit losses, excluding the provision for covered loan losses, totaled $11.0 million for the third quarter of 2018 compared to $5.0 million for the second quarter of 2018 and $7.9 million for the third quarter of 2017. The provision for credit losses in the third quarter was driven by $7.5 million of specific reserves related to four non-performing credit relationships.

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.

The following table presents the provision for credit losses and allowance for credit losses by component for the periods presented, including covered loans:

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 September 30, 2018 and June 30, 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 $149.8 million of allowance for loan losses, there is $3.7 million of non-accretable credit discount on purchased loans reported in accordance with ASC 310-30 that is available to absorb credit losses.

(1) As of the dates shown, no TDRs were past due greater than 90 days and still accruing interest.
(2) Non-accrual loans included TDRs totaling $34.7 million, $8.1 million and $6.2 million as of September 30, 2018, June 30, 2018 and September 30, 2017, respectively.

The ratio of non-performing assets to total assets was 0.52% as of September 30, 2018, compared to 0.40% at June 30, 2018, and 0.42% at September 30, 2017. Non-performing assets, excluding covered assets and non-covered PCI loans, totaled $155.8 million at September 30, 2018, compared to $118.9 million at June 30, 2018 and $115.7 million at September 30, 2017. Non-performing loans, excluding covered loans and non-covered PCI loans, totaled $127.2 million, or 0.55% of total loans, at September 30, 2018 compared to $83.3 million, or 0.37% of total loans, at June 30, 2018 and $78.0 million, or 0.37% of total loans, at September 30, 2017. The increase in the current quarter is primarily the result of four credit relationships within the commercial portfolio totaling $46.6 million becoming non-performing during the third quarter. OREO, excluding covered OREO, of $28.3 million at September 30, 2018 decreased $7.0 million compared to $35.3 million at June 30, 2018 and decreased $9.1 million compared to $37.4 million at September 30, 2017.

Management is pursuing the resolution of all credits in this category. At this time, management believes reserves are appropriate to absorb inherent losses that are expected upon the ultimate resolution of these credits.

Items Impacting Comparative Financial Results:

Acquisitions

On August 1, 2018, the Company completed its acquisition of Chicago Shore Corporation ("CSC"). CSC was the parent company of Delaware Place Bank. Through this transaction, the Company acquired Delaware Place Bank's one banking location in Chicago, Illinois, approximately $280 million in assets and approximately $213 million in deposits.

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.
