Wintrust Financial Corporation Reports Record Third Quarter 2013 Net Income of $35.6 Million, an Increase of 10% and Record Year-To-Date Net Income of $101.9 Million, an Increase of 26%

ROSEMONT, ILLINOIS – Wintrust Financial Corporation (“Wintrust” or “the Company”) (Nasdaq: WTFC) announced net income of $35.6 million or $0.71 per diluted common share for the third quarter of 2013 compared to net income of $34.3 million or $0.69 per diluted common share for the second quarter of 2013 and $32.3 million or $0.66 per diluted common share for the third quarter of 2012. On a year-to-date basis, the Company recorded record net income of $101.9 million or $2.05 per diluted common share for the first nine months of 2013 compared to net income of $81.1 million or $1.70 per diluted common share for the first nine months of 2012.

Highlights compared with the Second Quarter of 2013*:

• Net income increased by $1.3 million

• Net interest margin, on a fully taxable-equivalent basis, improved by seven basis points to 3.57% from 3.50%

• Total loans, excluding covered loans, mortgage loans held-for-sale and mortgage warehouse loans, increased by $167 million

• Total deposits increased by $282 million of which $172 million was attributed to non-interest bearing deposit accounts

• Provision for credit losses decreased by $4.3 million

• Net charge-offs declined by $7.1 million from $18.4 million to $11.3 million

• Decrease in trading gains of $4.9 million primarily related to the mark-to-market valuation of interest rate cap derivatives

• Conversion of Series A Preferred Stock effectively increasing income available to common shareholders by $1.0 million

• Announced the acquisition of Diamond Bancorp, Inc.

* See "Supplemental Financial Measures/Ratios" on page 14/15 for more information on non-GAAP measures.

Edward J. Wehmer, President and Chief Executive Officer, commented, “Wintrust reported record levels of net income for a quarterly and nine month period. The third quarter of 2013 was highlighted by an increased net interest margin, stable non-performing asset levels, continued loan growth and the announcement of the acquisition of Diamond Bancorp."

Mr. Wehmer continued, “Net interest margin, on a fully taxable-equivalent basis, improved to 3.57% as compared to 3.50% in both the second quarter of 2013 and third quarter of 2012. The current quarter's net interest margin, on a fully taxable-equivalent basis, is the highest the company has recorded since the second quarter of 2001. Net interest margin has continued to improve as a result of a more desirable deposit mix and repricing of customer deposit accounts combined with loan growth."

 Commenting on credit quality, Mr. Wehmer noted, “The Company's non-performing asset levels remained stable in the third quarter of 2013. In fact, the Company recorded its lowest level of quarterly net charge-offs since the first quarter of 2009. Additionally, the ratio of non-performing assets to total assets declined for the second consecutive quarter. Our credit workout teams continue to make good progress on addressing non-performing assets."

Mr. Wehmer further commented, “We recently announced the acquisition of certain assets and liabilities of Surety Financial Services. Surety originated approximately $1.0 billion in mortgage loans during the previous twelve months, an amount approximately equal to one quarter of the annual originations of our existing mortgage banking business. We believe that the

1

addition of Surety will allow us to take advantage of an improving home purchase market as the refinance market softens. As a result, we anticipate that a decline in originations from our existing mortgage banking business in the fourth quarter will be partially offset by origination activity added from the Surety acquisition. We will continue to evaluate organic and acquisition opportunities to expand our mortgage banking business."

Turning to the future, Mr. Wehmer stated, “We are excited about the addition of Diamond Bank and Surety Financial to the Wintrust family. Evaluating strategic acquisitions of this nature and organic branch growth will continue to be a part of our overall growth strategy. Our pipelines for both internal growth and external growth remain consistently strong. Growing franchise value, increasing profitability, leveraging our expense infrastructure and increasing shareholder value continue to be our main objectives."

(1) Net revenue is net interest income plus non-interest income.

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

(3) 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.

(4) The efficiency ratio is calculated by dividing total non-interest expense by tax-equivalent net revenue (less securities gains or losses). A lower ratio indicates more efficient revenue generation.

(5) 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.

Financial Performance Overview – Third Quarter 2013

For the third quarter of 2013, net interest income totaled $141.8 million, an increase of $6.0 million as compared to the second quarter of 2013 and an increase of $9.2 million as compared to the third quarter of 2012. The net interest margin, on a fully taxable equivalent basis, for the third quarter of 2013 was 3.57% compared to 3.50% in both the second quarter of 2013 and the third quarter of 2012. The changes in net interest income on both a sequential and linked quarter basis are the result of the following:

• Net interest income increased $6.0 million in the third quarter of 2013 compared to the second quarter of 2013, due to:

◦ An increase in total interest income of $4.5 million in the third quarter of 2013 compared to the second quarter of 2013 resulting from a one basis point increase in the yield on earning assets, one additional day in the current quarter, and a $215.2 million increase in average earning assets.              

◦ A $1.5 million reduction in interest expense in the third quarter of 2013 compared to the second quarter of 2013 created by a five basis point decline in the rate paid on total interest-bearing liabilities partially offset by an increase in average interest-bearing liabilities of $51.1 million and one additional day in the current quarter.

◦ Combined, the increase in interest income of $4.5 million and the reduction of interest expense by $1.5 million created the $6.0 million increase in net interest income in the third quarter of 2013 compared to the second quarter of 2013. 

• Net interest income increased $9.2 million in the third quarter of 2013 compared to the third quarter of 2012, due to:

◦ Average earning assets for the third quarter of 2013 increased by $723.1 million compared to the third quarter of 2012. This was comprised of average loan growth, excluding covered loans, of $1.2 billion partially offset by a decrease of $306.0 million in the average balance of liquidity management and other assets and a decrease of $161.6 million in the average balance of covered loans. The growth in average total loans, excluding covered loans, included an increase of $410.3 million in commercial loans, $470.1 million in commercial real-estate loans, $230.6 million in U.S.-originated commercial premium finance receivables, $28.2 million in Canadian-originated commercial premium finance receivables and $170.0 million in life premium finance receivables, partially offset by a decrease of $59.9 million in mortgage loans held-for-sale and $58.7 million in home equity and other loans.

◦ The average earning asset growth of $723.1 million in the third quarter of 2013 compared to the third quarter of 2012 was partially offset by a 13 basis point decline in the yield on earning assets, creating an increase in total interest income of $3.0 million in the third quarter of 2013 compared to the prior year quarter.

◦ Funding for the average earning asset growth of $723.1 million was provided by an increase in total average interest bearing liabilities of $217.3 million (an increase in interest-bearing deposits of $556.5 million partially offset by a decrease of $339.1 million of wholesale funding) and an increase of $505.8 million in the average balance of net free funds.

◦ A $6.2 million reduction in interest expense in the third quarter of 2013 compared to the third quarter of 2012 created by a 21 basis point decline in the rate paid on total interest-bearing liabilities partially offset by the increase in average balance.

◦ Combined, the increase in interest income of $3.0 million and the reduction of interest expense by $6.2 million created the $9.2 million increase in net interest income in the third quarter of 2013 compared to the third quarter of 2012.

Non-interest income totaled $54.7 million in the third quarter of 2013, decreasing $9.3 million or 15%, compared to the second quarter of 2013 and decreasing $8.3 million, or 13%, compared to the third quarter of 2012. The decrease in non-interest income in the third quarter of 2013 compared to the second quarter of 2013 is primarily attributable to a decrease in mortgage banking revenues and trading losses resulting primarily from a decrease in the valuation of interest rate cap derivatives, partially offset by an increase in FDIC indemnification asset accretion. The decrease in non-interest income in the third quarter of 2013 compared to the third quarter of 2012 was primarily attributable to bargain purchase gains recorded in the prior year quarter, lower mortgage banking revenues and a decrease in fees from covered call options, partially offset by higher wealth management revenues, increased FDIC indemnification asset accretion and foreign currency remeasurement gains. The increase in FDIC indemnification asset accretion in the current quarter compared to the second quarter of 2013 and third quarter of 2012 reflects a benefit arising from adjusting certain factors, primarily from an evaluation of our cumulative service costs, which in turn reduced our projected clawback liability. Mortgage banking revenue decreased $6.1 million when compared to the second quarter of 2013 and $5.4 million when compared to the third quarter of 2012. The decreases in mortgage banking revenue from the second quarter of 2013

7

and the third quarter of 2012 resulted primarily from decreased loan originations due to the impact of higher rates on refinancing activity as well as competitive pricing pressure. Loans originated and sold to the secondary market were $940.8 million in the third quarter of 2013 compared to $1.1 billion in both the second quarter of 2013 and the third quarter of 2012 (see “Non-Interest Income” section later in this release for further detail).

Non-interest expense totaled $127.2 million in the third quarter of 2013, decreasing $939,000 or 1%, compared to the second quarter of 2013 and increasing $2.7 million, or 2%, compared to the third quarter of 2012. The decrease in the current quarter compared to the second quarter of 2013 can be attributed to a $1.7 million decrease in commission and bonus expense primarily driven by lower revenues in the mortgage banking business and an $813,000 decrease in professional fees, mostly comprised of legal fees, partially offset by a $1.1 million increase in salary expense. The increase in the third quarter of 2013 compared to the third quarter of 2012 was primarily attributable to higher salary and employee benefit costs and increased occupancy, data processing and equipment expenses, partially offset by a decrease in OREO expenses and professional fees (see "Non-Interest Expense" section later in this release for further detail).

Financial Performance Overview – First Nine Months of 2013

The net interest margin, on a fully taxable equivalent basis, for the first nine months of 2013 was 3.49% compared to 3.52% in the first nine months of 2012. Net interest income increased $21.6 million in the first nine months of 2013 compared to the first nine months of 2012, due to:

◦ Average earning assets for the first nine months of 2013 increased by $960.2 million compared to the first nine months of 2012. This was comprised of average loan growth, excluding covered loans, of $1.3 billion partially offset by a decrease of $153.8 million in the average balance of covered loans and a decrease of $167.6 million in the average balance of liquidity management and other assets.

◦ The yield on earnings assets declined by 26 basis points in the first nine months of 2013 compared to the first nine months of 2012. The decrease in the yield on earning assets was partially offset by the increase in average earning assets, creating a decrease in total interest income of $251,000 in the first nine months of 2013 compared to the prior year period.

◦ Funding for the average earning asset growth of $960.2 million was provided by an increase in total average interest-bearing liabilities of $365.2 million (an increase in interest-bearing deposits of $959.5 million partially offset by a decrease of $594.3 million of wholesale funding) and an increase of $595.0 million in the average balance of net free funds.

◦ A $21.8 million reduction in interest expense in the first nine months of 2013 compared to the first nine months of 2012 created by a 26 basis point decline in the rate paid on total interest-bearing liabilities partially offset by the increase in average balance.

◦ Combined, the reduction of interest expense by $21.8 million and the decline in interest income of $251,000, created the $21.6 million increase in net interest income in the first nine months of 2013 compared to the first nine months of 2012.

Non-interest income totaled $176.0 million in the first nine months of 2013, increasing $15.1 million, or 9%, compared to the first nine months of 2012. The change is primarily attributable to higher mortgage banking revenues, wealth management revenues and trading gains, partially offset by lower bargain purchase gains, decreased fees from covered call options and fewer gains on available for sale securities. Mortgage banking revenue increased $12.3 million when compared to the first nine months of 2012. The increase in the first nine months of 2013 resulted primarily from an increase in gains on sales of loans, which was driven by higher origination volumes primarily due to increased home purchase activity resulting from improvements in the housing market. Loans originated and sold to the secondary market were $3.0 billion in the first nine months of 2013 compared to $2.7 billion in the first nine months of 2012.

Non-interest expense totaled $375.6 million in the first nine months of 2013, increasing $16.1 million compared to the first nine months of 2012. The increase compared to the first nine months of 2012 was primarily attributable to a $22.3 million increase in salaries and employee benefits, as well as increases of $2.8 million in occupancy expenses, $2.4 million in equipment expenses and $2.3 million in data processing expenses, partially offset by a $13.7 million decline in OREO expenses.

Financial Performance Overview – Credit Quality

The ratio of non-performing assets to total assets was 1.01% as of September 30, 2013, compared to 1.02% at June 30, 2013 and 1.09% at September 30, 2012. Non-performing assets, excluding covered assets, totaled $179.0 million at September 30, 2013, compared to $179.5 million at June 30, 2013 and $185.3 million at September 30, 2012.

Non-performing loans, excluding covered loans, totaled $123.3 million, or 0.98% of total loans, at September 30, 2013, compared to $121.5 million, or 0.97% of total loans, at June 30, 2013 and $117.9 million, or 1.03% of total loans, at September 30, 2012. OREO, excluding covered OREO, of $55.3 million at September 30, 2013 decreased $1.7 million compared to $57.0 million at June 30, 2013 and decreased $12.1 million compared to $67.4 million at September 30, 2012.

The provision for credit losses, excluding the provision for covered loan losses, totaled $11.6 million for the third quarter of 2013 compared to $15.1 million for the second quarter of 2013 and $18.2 million in the third quarter of 2012. Net charge-offs as a percentage of loans, excluding covered loans, for the third quarter of 2013 totaled 34 basis points on an annualized basis compared to 59 basis points on an annualized basis in the second quarter of 2013 and 60 basis points on an annualized basis in the third quarter of 2012. Net charge-offs decreased in the third quarter of 2013 compared to the second quarter of 2013 primarily as a result of a $7.7 million decrease in net charge-offs within the commercial real estate loan portfolio and a $946,000 decrease within the home equity portfolio, partially offset by a $1.7 million increase within the commercial loan portfolio.

Excluding the allowance for covered loan losses, the allowance for credit losses at September 30, 2013 totaled $108.5 million, or 0.86% of total loans, compared to $110.4 million, or 0.88% of total loans at June 30, 2013 and $124.9 million, or 1.09% of total loans at September 30, 2012. The decrease in the allowance for credit losses, excluding the allowance for covered loan losses, was primarily attributable to a decrease in the allowance for unfunded lending-related commitments during both periods. As of September 30, 2013, the allowance for unfunded lending-related commitments totaled $1.3 million compared to $3.6 million as of June 30, 2013 and $12.6 million as of September 30, 2012. The decrease when comparing both periods was primarily the result of the funding of two letters of credit in the second and third quarters of 2013.

Net income applicable to common shares—Basic	(A)	33,982		29,686		95,108		74,630
Add: Dividends on convertible preferred stock, if dilutive		1,581		2,581		6,744		6,374
Net income applicable to common shares—Diluted	(B)	35,563		32,267		101,852		81,004
Weighted average common shares outstanding	(C)	39,331		36,381		37,939		36,305
Effect of dilutive potential common shares:
Common stock equivalents		7,346		7,275		7,263		7,159
Convertible preferred stock, if dilutive		3,477		5,020		4,500		4,133
Weighted average common shares and effect of dilutive potential common shares	(D)	50,154		48,676		49,702		47,597
Net income per common share:
Basic	(A/C)	$	0.86	$	0.82	$	2.51	$	2.06
Diluted	(B/D)	$	0.71	$	0.66	$	2.05	$	1.70

Potentially dilutive common shares can result from stock options, restricted stock unit awards, stock warrants, the Company’s convertible preferred stock, tangible equity unit shares 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, net income applicable to common shares is not adjusted by the associated preferred dividends.

(4) The efficiency ratio is calculated by dividing total non-interest expense by tax-equivalent net revenue (less securities gains or losses). A lower ratio indicates more efficient revenue generation.

(5) Capital ratios for current quarter-end are estimated.

(6) The allowance for credit losses includes both the allowance for loan losses and the allowance for unfunded lending-related commitments, but excludes the allowance for covered loan losses.

(7) Total shareholders’ equity minus preferred stock and total intangible assets divided by total assets minus total intangible assets.

(8) Asset quality ratios exclude covered loans.

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), net interest margin (including its individual components), the efficiency ratio, tangible common equity ratio, tangible common book value per share, return on average tangible common equity and pre-tax adjusted earnings. Management believes that these measures and ratios provide users of the Company’s financial information a more meaningful view of the performance of the 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. 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. Pre-tax adjusted earnings is a significant metric in assessing the Company’s operating performance. Pre-tax adjusted earnings is calculated by adjusting income before taxes to exclude the provision for credit losses and certain significant items.

The net overhead ratio and the efficiency ratio are primarily reviewed by the Company based on pre-tax adjusted earnings. The Company believes that these measures provide a more meaningful view of the Company’s operating efficiency and expense management. The net overhead ratio, based on pre-tax adjusted earnings, is calculated by netting total adjusted non-interest expense and total adjusted non-interest income, annualizing this amount, and dividing it by total average assets. Adjusted non-interest expense is calculated by subtracting OREO expenses, covered loan collection expense, defeasance cost, seasonal payroll tax fluctuation and fees to terminate repurchase agreements. Adjusted non-interest income is calculated by adding back the recourse obligation on loans previously sold and subtracting gains or adding back losses on FDIC indemnification asset accretion, foreign currency remeasurement, investment partnerships, bargain purchase, trading and available-for-sale securities activity.

The efficiency ratio, based on pre-tax adjusted earnings, is calculated by dividing adjusted non-interest expense by adjusted taxable-equivalent net revenue. Adjusted taxable-equivalent net revenue is comprised of fully taxable equivalent net interest income and adjusted non-interest income.

NON-INTEREST INCOME

For the third quarter of 2013, non-interest income totaled $54.7 million, a decrease of $8.3 million, or 13%, compared to the third quarter of 2012. The decrease was primarily attributable to bargain purchase gains recorded in the prior year quarter, lower mortgage banking revenues and a decrease in fees from covered call options, partially offset by higher wealth management revenues and miscellaneous income.

The following table presents non-interest income by category for the periods presented:

Wealth management revenue totaled $16.1 million in the third quarter of 2013 compared to $13.3 million in the third quarter of 2012, an increase of 21%. The increase is mostly attributable to growth in assets from new customers and new financial advisors, as well as an increase in existing customer activity and market appreciation. 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, money managed fees and insurance product commissions at Wayne Hummer Investments.

For the quarter ended September 30, 2013, mortgage banking revenue totaled $25.7 million, a decrease of $5.4 million or 17%, when compared to the third quarter of 2012. The decrease in mortgage banking revenue in the third quarter of 2013 as compared to the third quarter of 2012 resulted primarily from lower origination volumes as refinance activity declined as well as competitive pricing pressure. Mortgage loan originations were $940.8 million in the third quarter of 2013 as compared to $1.1 billion in the prior year quarter. Mortgage banking revenue includes revenue from activities related to originating, selling and servicing residential real estate loans for the secondary market.

A summary of mortgage banking components is shown below:

Fair value of mortgage servicing rights (MSRs)	8,608			8,636			6,276
MSRs as a percentage of loans serviced	0.88		%	0.87		%	0.63		%

Service charges on deposit accounts totaled $5.3 million in the third quarter of 2013, an increase of $1.1 million compared to the prior year quarter. The increase in the current quarter is primarily a result of higher account analysis fees on deposit accounts which have increased as a result of the Company's commercial banking initiative as well as additional service charges on deposit accounts from acquired institutions.

Fees from covered call option transactions decreased by $1.8 million in the third quarter of 2013 as compared to the same period in the prior year. Fees from covered call options decreased primarily as a result of fewer option transactions entered in the third quarter of 2013 compared to the third quarter of 2012 resulting in lower premiums received by the Company. 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. Historically, the Company has effectively entered into these transactions with the goal of 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 increase the total return associated with holding certain investment securities that do not qualify as hedges pursuant to accounting guidance. An illustration of the past effectiveness of this strategy is shown in the Supplemental Financial Information section (see page titled “Net Interest Margin (Including Call Option Income)”).

Gain on bargain purchases for the current quarter decreased by $6.6 million compared to the third quarter of 2012. The Company recognized gains on bargain purchases in the prior year quarter related to the acquisition of First United Bank.

The Company recognized $1.7 million in trading losses in the third quarter of 2013 compared to trading losses of $998,000 in the third quarter of 2012. The increase in trading losses resulted primarily from fair value adjustments related to interest rate derivatives not designated as hedges, primarily interest rate cap instruments that the Company uses to manage interest rate risk, specifically in the event of future increases in short-term interest rates. The change in value of the cap derivatives reflects the present value of expected cash flows over the remaining life of the caps. These expected cash flows are derived from the expected path for and a measure of volatility for short-term interest rates.

Other non-interest income for the third quarter of 2013 totaled $8.9 million, an increase of $2.7 million compared to the third quarter of 2012. Miscellaneous income increased in the third quarter of 2013 compared to the prior year quarter primarily as a result of increased FDIC indemnification asset accretion and foreign currency remeasurement gains in the current quarter. The increase in FDIC indemnification asset accretion in the current quarter compared to the third quarter of 2012 reflects a benefit arising from adjusting certain factors, primarily from an evaluation of our cumulative service costs, which in turn reduced our projected clawback liability.

NON-INTEREST EXPENSE

Non-interest expense for the third quarter of 2013 totaled $127.2 million and increased approximately $2.7 million, or 2%, compared to the third quarter of 2012. The increase was primarily attributable to higher salary and employee benefit costs and increased occupancy, data processing and equipment expenses, partially offset by a decrease in OREO expenses and professional fees.

The significant changes in non-interest expense for the quarter ended September 30, 2013 compared to the quarter ended September 30, 2012 are discussed below.

Salaries and employee benefits expense increased $2.7 million, or 4%, in the third quarter of 2013 compared to the third quarter of 2012 primarily as a result of a $2.6 million increase in salaries caused by the addition of employees from the various acquisitions and larger staffing as the Company grows and a $743,000 increase in employee benefits partially offset by a $632,000 decrease in bonus and commissions primarily attributable to the decrease in variable pay based revenue and the Company's long-term incentive program.

Equipment expense totaled $6.6 million for the third quarter of 2013, an increase of $705,000 compared to the third quarter of 2012. The increase is primarily related to additional equipment depreciation as a result of acquisitions as well as increased software license fees. Equipment expense includes depreciation on equipment, maintenance and repairs, equipment rental and software license fees.

Occupancy expense for the third quarter of 2013 was $9.1 million, an increase of $1.1 million, or 13%, compared to the same period in 2012. The increase is primarily the result of depreciation and maintenance and repairs on owned locations including those obtained in the Company's acquisitions as well as increased property taxes, partially offset by increased rental income. Occupancy expense includes depreciation on premises, real estate taxes, utilities and maintenance of premises, as well as net rent expense for leased premises.

Data processing expenses increased $781,000 in the third quarter of 2013 totaling $4.9 million compared to $4.1 million recorded in the third quarter of 2012. The amount of data processing expenses incurred fluctuates based on the overall growth of loan and deposit accounts as well as additional expenses recorded related to bank acquisition transactions. Data processing expenses increased in the current quarter compared to the previous year quarter primarily as a result of conversion expenses at acquired banks.

Professional fees for the third quarter of 2013 were $3.4 million, a decrease of $1.3 million, or 27%, compared to the same period in 2012. This decrease is primarily a result of reduced legal costs in current quarter. Professional fees include legal, audit and tax fees, external loan review costs and normal regulatory exam assessments.

OREO expense totaled $2.5 million in the third quarter of 2013 compared to OREO expense of $3.8 million recorded in the third quarter of 2012. OREO expense was lower in the current quarter as compared to the third quarter of 2012 due to higher gains on sales of OREO properties in the current quarter. OREO costs include all costs related to obtaining, maintaining and selling other real estate owned properties.

Miscellaneous expenses in the third quarter of 2013 decreased $361,000, or 3%, compared to the same period in the prior year. Miscellaneous expense includes ATM expenses, correspondent bank charges, directors' fees, telephone, travel and entertainment, corporate insurance, dues and subscriptions, problem loan expenses and lending origination costs that are not deferred.

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).

The provision for credit losses, excluding the provision for covered loan losses, totaled $11.6 million for the third quarter of 2013, $15.1 million for the second quarter of 2013 and $18.2 million for the third quarter of 2012. For the quarter ended September 30, 2013, net charge-offs, excluding covered loans, totaled $11.3 million compared to $18.4 million in the second quarter of 2013 and $17.9 million recorded in the third quarter of 2012. Annualized net charge-offs as a percentage of average loans, excluding covered loans, were 0.34% in the third quarter of 2013, 0.59% in the second quarter of 2013 and 0.60% in the third quarter of 2012. Net charge-offs decreased in the third quarter of 2013 compared to the second quarter of 2013 primarily as a result of a $7.7 million decrease in net charge-offs within the commercial real estate loan portfolio and a $946,000 decrease within the home equity portfolio, partially offset by a $1.7 million decrease within the commercial loan portfolio.

The allowance for unfunded lending-related commitments totaled $1.3 million as of September 30, 2013 compared to $3.6 million as of June 30, 2013 and $12.6 million as of September 30, 2012. The decrease when comparing both periods was primarily attributable to the funding in the second and third quarter of 2013 of two letters of credit. The lower level of the allowance for credit losses in 2013, reflects the improvements in credit quality metrics compared to 2012.

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 provides a provision for covered loan losses on covered loans and maintains an allowance for covered loan losses on covered loans. Please see “Covered Assets” later in this document for more detail.

(3) The June 30, 2013 reported asset-based lending portfolio decreased approximately $245 million, and the reported commercial and industrial and mixed use and other portfolios increased approximately $244 million and $645,000, respectively. These adjustments are the result of a re-assessment of characteristics of certain loans within these portfolios. Reclassification of these prior period amounts have been made to conform with current period presentation.

29

As part of a 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 previous pages as of September 30, 2013 and June 30, 2013. The allowance for loan losses to core loans was 1.25% compared to 0.23% for consumer, niche and purchased loans and 0.85% for the entire loan portfolio as of September 30, 2013. As of June 30, 2013, the allowance for loan losses to core loans was 1.27% compared to 0.23% for consumer, niche and purchased loans and 0.85% for the entire loan portfolio.

The decrease in the allowance for loan losses to core loans in the third quarter of 2013 compared to the second quarter of 2013 was attributable to an increase in core loans requiring ASC 450 reserves (general reserves). The ASC 450 reserve as a percentage of core loans was 1.09% at September 30, 2013 and 1.14% at June 30, 2013. The decrease was attributable to lower ASC 450 reserve factors, which are influenced by declining historical charge-offs. This effect on the allowance for loan losses to core loans was partially offset by a $2.4 million increase in ASC 310 reserves (specific reserves) on the core portfolio.

Non-performing Commercial and Commercial Real Estate

Commercial non-performing loans totaled $17.8 million as of September 30, 2013 compared to $17.3 million as of June 30, 2013 and $17.7 million as of September 30, 2012. Commercial real estate non-performing loans totaled $56.1 million as of September 30, 2013 compared to $58.1 million as of June 30, 2013 and $58.5 million as of September 30, 2012.

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 to occur upon the ultimate resolution of these credits.

Non-performing Residential Real Estate and Home Equity

Non-performing home equity and residential real estate loans totaled $25.1 million as of September 30, 2013. The balance increased $2.5 million from June 30, 2013 and decreased $1.8 million from September 30, 2012. The September 30, 2013 non-performing balance is comprised of $14.1 million of residential real estate (69 individual credits) and $11.0 million of home equity loans (50 individual credits). On average, this is approximately 8 non-performing residential real estate loans and home equity loans per chartered bank within the Company. The Company believes control and collection of these loans is very manageable. At this time, management believes reserves are adequate to absorb inherent losses that may occur upon the ultimate resolution of these credits.

Non-performing Commercial Insurance Premium Finance Receivables

The table below presents the level of non-performing property and casualty premium finance receivables as of September 30, 2013 and 2012, and the amount of net charge-offs for the quarters then ended.

	September 30,			September 30,
(Dollars in thousands)	2013			2012
Non-performing premium finance receivables - commercial	$	21,883		$	13,021
- as a percent of premium finance receivables - commercial outstanding	1.02		%	0.66		%
Net charge-offs of premium finance receivables - commercial	$	980		$	695
- annualized as a percent of average premium finance receivables - commercial	0.17		%	0.14		%

Fluctuations in this category may occur due to timing and nature of account collections from insurance carriers. The Company’s underwriting standards, regardless of the condition of the economy, have remained consistent. We anticipate that net charge-offs and non-performing asset levels in the near term will continue to be at levels that are within acceptable operating ranges for this category of loans. Management is comfortable with administering the collections at this level of non-performing property and casualty premium finance receivables and believes reserves are adequate to absorb inherent losses that may occur upon the ultimate resolution of these credits.

Due to the nature of collateral for commercial premium finance receivables, it customarily takes 60-150 days to convert the collateral into cash. Accordingly, the level of non-performing commercial premium finance receivables is not necessarily indicative of the loss inherent in the portfolio. In the event of default, Wintrust has the power to cancel the insurance policy and collect the unearned portion of the premium from the insurance carrier. In the event of cancellation, the cash returned in payment of the unearned premium by the insurer should generally be sufficient to cover the receivable balance, the interest and other charges due. Due to notification requirements and processing time by most insurance carriers, many receivables will become delinquent beyond 90 days while the insurer is processing the return of the unearned premium. Management continues to accrue interest until maturity as the unearned premium is ordinarily sufficient to pay-off the outstanding balance and contractual interest due.

(1) Loan was previously classified as a troubled debt restructuring and subsequently performed in compliance with the loan’s modified terms for a period of six months (including over a calendar year-end) at a modified interest rate which represented a market rate at the time of restructuring. Per our TDR policy, the TDR classification is removed.

The Company’s approach to restructuring loans, excluding those acquired with evidence of credit quality deterioration since origination, is built on its credit risk rating system which requires credit management personnel to assign a credit risk rating to each loan at the time of each modification. In each case, the loan officer is responsible for recommending a credit risk rating for each loan and ensuring the credit risk ratings are appropriate. These credit risk ratings are then reviewed and approved by the bank’s chief credit officer and/or concurrence credit officer. Credit risk ratings are determined by evaluating a number of factors including a borrower’s financial strength, cash flow coverage, collateral protection and guarantees. The Company’s credit risk rating scale is one through ten with higher scores indicating higher risk. In the case of loans rated six or worse following modification, the Company’s Managed Assets Division evaluates the loan and the credit risk rating and determines that the loan has been restructured to be reasonably assured of repayment and of performance according to the modified terms and is supported by a current, well-documented credit assessment of the borrower’s financial condition and prospects for repayment under the revised terms.

A modification of a loan, excluding those acquired with evidence of credit quality deterioration since origination, with an existing credit risk rating of six or worse or a modification of any other credit, which will result in a restructured credit risk rating of six or worse must be reviewed for TDR classification. In that event, our Managed Assets Division conducts an overall credit and collateral review. A modification of a loan is considered to be a TDR if both (1) the borrower is experiencing financial difficulty and (2) for economic or legal reasons, the bank grants a concession to a borrower that it would not otherwise consider. The modification of a loan, excluding those acquired with evidence of credit quality deterioration since origination, where the credit risk rating is five or better both before and after such modification is not considered to be a TDR. Based on the Company’s credit risk rating system, it considers that borrowers whose credit risk rating is five or better are not experiencing financial difficulties and therefore, are not considered TDRs.

All credits determined to be a TDR will continue to be classified as a TDR in all subsequent periods, unless the borrower has been in compliance with the loan’s modified terms for a period of six months (including over a calendar year-end) and the modified interest rate represented a market rate at the time of a restructuring. The Managed Assets Division, in consultation with the respective loan officer, determines whether the modified interest rate represented a current market rate at the time of restructuring. Using knowledge of current market conditions and rates, competitive pricing on recent loan originations, and an assessment of various characteristics of the modified loan (including collateral position and payment history), an appropriate market rate for a new borrower with similar risk is determined. If the modified interest rate meets or exceeds this market rate for a new borrower with similar risk, the modified interest rate represents a market rate at the time of restructuring. Additionally, before removing a loan from TDR classification, a review of the current or previously measured impairment on the loan and any concerns related to future performance by the borrower is conducted. If concerns exist about the future ability of the borrower to meet its obligations under the loans based on a credit review by the Managed Assets Division, the TDR classification is not removed from the loan. Loans classified as TDRs that are re-modified subsequent to the initial determination will continue to be classified as TDRs following the re-modification, unless the requirements for removal from TDR classification discussed above are satisfied at the time of the re-modification.

TDRs are reviewed at the time of modification and on a quarterly basis to determine if a specific reserve is needed. The carrying amount of the loan is compared to the expected payments to be received, discounted at the loan’s original rate, or for collateral

39

dependent loans, to the fair value of the collateral. Any shortfall is recorded as a specific reserve. The Company, in accordance with ASC 310-10, continues to individually measure impairment of these loans after the TDR classification is removed.

Each TDR was reviewed for impairment at September 30, 2013 and approximately $4.4 million of impairment was present and appropriately reserved for through the Company’s normal reserving methodology in the Company’s allowance for loan losses. For TDRs in which impairment is calculated by the present value of future cash flows, the Company records interest income representing the decrease in impairment resulting from the passage of time during the respective period, which differs from interest income from contractually required interest on these specific loans. For the three months ended September 30, 2013 and 2012, the Company recorded $205,000 and $534,000, respectively, in interest income representing this decrease in impairment. For the nine months ended September 30, 2013 and 2012, the Company recorded $727,000 and $1.0 million, respectively, in interest income representing this decrease in impairment.

Covered Assets

In conjunction with FDIC-assisted transactions, the Company entered into loss share agreements with the FDIC. These agreements cover realized losses on loans, foreclosed real estate and certain other assets. These loss share assets are measured separately from the loan portfolios because they are not contractually embedded in the loans and are not transferable with the loans should the Company choose to dispose of them. Fair values at the acquisition dates were estimated based on projected cash flows available for loss-share based on the credit adjustments estimated for each loan pool and the loss share percentages. The loss share assets are also separately measured from the related loans and foreclosed real estate and recorded separately on the Consolidated Statements of Condition. Subsequent to the acquisition date, reimbursements received from the FDIC for actual incurred losses will reduce the loss share assets. Additional expected losses, to the extent such expected losses result in the recognition of an allowance for loan losses, will increase the loss share assets. The loss share agreements with the FDIC require the Company to reimburse the FDIC in the event that actual losses on covered assets are lower than the original loss estimates agreed upon with the FDIC with respect of such assets in the loss share agreements. The allowance for loan losses for loans acquired in FDIC-assisted transactions is determined without giving consideration to the amounts recoverable through loss share agreements (since the loss share agreements are separately accounted for and thus presented “gross” on the balance sheet). On the Consolidated Statements of Income, the provision for credit losses is reported net of changes in the amount recoverable under the loss share agreements. Reductions to expected losses, to the extent such reductions to expected losses are the result of an improvement to the actual or expected cash flows from the covered assets, will reduce the loss share assets. The increases in cash flows for the purchased loans are recognized as interest income prospectively.

Changes in Accretable Yield

The excess of cash flows expected to be collected over the carrying value of loans accounted for under ASC 310-30 is referred to as the accretable yield and is recognized in interest income using an effective yield method over the remaining life of the pool of loans. The accretable yield is affected by:

• Changes in interest rate indices for variable rate loans accounted for under ASC 310-30 – Expected future cash flows are based on the variable rates in effect at the time of the regular evaluations of cash flows expected to be collected;

• Changes in prepayment assumptions – Prepayments affect the estimated life of loans accounted for under ASC 310-30 which may change the amount of interest income, and possibly principal, expected to be collected; and

• Changes in the expected principal and interest payments over the estimated life – Updates to expected cash flows are driven by the credit outlook and actions taken with borrowers. Changes in expected future cash flows from loan modifications are included in the regular evaluations of cash flows expected to be collected.

The following table provides activity for the accretable yield of loans accounted for under ASC 310-30.

Loans comprise the majority of the assets acquired in the FDIC-assisted transactions and are subject to loss sharing agreements with the FDIC where the FDIC has agreed to reimburse the Company for 80% of losses incurred on the purchased loans. Additionally, the loss share agreements with the FDIC require the Company to reimburse the FDIC in the event that actual losses on covered assets are lower than the original loss estimates agreed upon with the FDIC with respect to such assets in the loss share agreements. We refer to the loans subject to these loss-sharing agreements as “covered loans.” We use the term “covered assets” to refer to the total of covered loans, covered OREO and certain other covered assets. The agreements with the FDIC require that the Company follow certain servicing procedures or risk losing FDIC reimbursement of losses related to covered assets.

Divestiture of Previous FDIC-Assisted Acquisition

On February 1, 2013, Hinsdale Bank completed its divestiture of the deposits and current banking operations of Second Federal, which were acquired in an FDIC-assisted transaction on July 20, 2012, to Self-Help Federal Credit Union.

• environmental liability risk associated with lending activities;

• the impact of any claims or legal actions, including any effect on our reputation;

• losses incurred in connection with repurchases and indemnification payments related to mortgages;

• 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 possibility that certain European Union member states will default on their debt obligations, which may affect the Company’s liquidity, financial conditions and results of operations;

• examinations and challenges by tax authorities;

• changes in accounting standards, rules and interpretations and the impact on the Company’s financial statements;

• the ability of the Company to receive dividends from its subsidiaries;

• a decrease in the Company’s regulatory capital ratios, including as a result of further 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, including those resulting from the Dodd-Frank Act;

• 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;

• changes in 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;

(1) Net revenue includes net interest income and non-interest income

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

(3) 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.

(4) The efficiency ratio is calculated by dividing total non-interest expense by tax-equivalent net revenue (less securities gains or losses). A lower ratio indicates more efficient revenue generation.

(5) Capital ratios for current quarter-end are estimated.

(6) 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.

(7) Total shareholders’ equity minus preferred stock and total intangible assets divided by total assets minus total intangible assets

(8) Asset quality ratios exclude covered loans.
