WINTRUST FINANCIAL CORPORATION REPORTS
RECORD EARNINGS FOR THE THIRD QUARTER;
THIRD QUARTER NET EARNINGS UP 36%

          LAKE FOREST, ILLINOIS — Wintrust Financial Corporation (“Wintrust” or “the Company”) (Nasdaq: WTFC) announced record quarterly net income of $17.8 million for the quarter ended September 30, 2005, an increase of $4.7 million, or 36%, over the $13.1 million recorded in the third quarter of 2004. On a per share basis, net income for the third quarter of 2005 totaled $0.72 per diluted common share, a $0.12 per share, or 20%, increase as compared to the 2004 third quarter total of $0.60 per diluted common share. For the first nine months of 2005, net income totaled $50.0 million, or $2.07 per diluted common share, an increase of $12.8 million, or 35%, when compared to $37.2 million, or $1.71 per diluted common share, for the same period in 2004.

     Total assets rose to $7.89 billion at September 30, 2005, an increase of $2.07 billion, or 36%, compared to $5.82 billion a year ago. Total deposits as of September 30, 2005 were $6.49 billion, an increase of $1.74 billion, or 37%, as compared to $4.75 billion at September 30, 2004. Total loans grew to $5.15 billion as of September 30, 2005, a $1.15 billion, or 29%, increase over the $4.00 billion balance as of a year ago. Shareholders’ equity increased to $613.8 million, or a book value of $25.95 per share, at September 30, 2005, compared to $430.2 million, or a book value of $20.42, per share at September 30, 2004.

     “We are pleased to report another quarter of record earnings. Annualized double-digit deposit growth continued in the third quarter. This, coupled with strong but slower loan growth, resulted in a continued higher reliance on lower yielding liquidity management assets this quarter,” commented Edward J. Wehmer, President and Chief Executive Officer. “The lower level of loans coupled with the flattening yield curve has restrained the anticipated improvement in our net interest margin which has remained relatively flat for the past five quarters.”

Mr. Wehmer added, “We continue to be focused on our performance measurement goals, with a commitment to improving our returns on assets and equity over the coming year. Through the efforts of each of our employees, we are comfortable with the existing range of the analysts’ earnings estimates for 2005 of $2.70 to $2.83 per share.”

     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, balance sheet growth rates are most often expressed in terms of an annual rate like 20%. As such, a 5% growth rate for a quarter would represent an annualized 20% growth rate.

Acquisitions

     On May 19, 2004, Wintrust announced the completion (effective date of May 1, 2004) of its acquisition of SGB Corporation d/b/a WestAmerica Mortgage Company (“WAMC”) and Guardian Real Estate Services, Inc. (“Guardian”), in stock and cash merger transactions (a total of 180,438 shares of common stock were issued). WAMC engages primarily in the origination and purchase of residential mortgages for sale into the secondary market. WAMC’s operations are conducted out of its offices located in Oakbrook Terrace, Illinois, with accounting, administrative and secondary marketing operations located in Greenwood Village, Colorado. Guardian provides document preparation and other loan closing services to WAMC and its network of mortgage brokers. Guardian is headquartered in Oakbrook Terrace, Illinois.

     On September 30, 2004, Wintrust announced the completion of its acquisition of Northview Financial Corporation (“Northview”) in a stock and cash merger transaction (475,148 shares of common stock were issued). Northview was the parent company of Northview Bank and Trust (“Northview Bank”) with locations in Northfield, Mundelein and Wheaton, Illinois, and Northview Mortgage, LLC. Northview Bank began operations as ade novobank in 1993. On December 13, 2004, Northview Bank’s locations in Northfield became part of Northbrook Bank & Trust Company, Northview Bank’s Mundelein location became part of Libertyville Bank & Trust Company and Northview Bank’s Wheaton location was renamed Wheaton Bank & Trust Company.

     On October 15, 2004, Wintrust announced the completion (effective date of October 1, 2004) of its acquisition of Town Bankshares, Ltd. (“Town”) in a stock and cash merger transaction (372,535 shares of common stock were issued). Town was the parent company of Town Bank with locations in Delafield and Madison, Wisconsin. Town Bank began operations as ade novobank in 1998.

     On January 18, 2005, Wintrust announced the completion (effective date of January 1, 2005) of its cash acquisition of Antioch Holding Company (“Antioch”). Antioch was the parent company of State Bank of The Lakes that has locations in Antioch, Lindenhurst, Grayslake, Spring Grove and McHenry.

Bank began operations as ade novobank in 1995. On May 23, 2005, FNBI’s locations became part of Village Bank & Trust.

     The results of operations of WAMC, Guardian, Northview, Town, Antioch and FNBI are included in Wintrust’s consolidated financial results only since their respective effective dates of acquisition.

Stock Offering/Regulatory Capital

     On March 30, 2005, Wintrust consummated the partial settlement of the forward sale agreement the Company entered into on December 14, 2004 with Royal Bank of Canada, an affiliate of RBC Capital Markets Corporation, relating to the forward sale by Wintrust of 1.2 million shares of Wintrust’s common stock. Pursuant to and in partial settlement of the forward sale agreement, Wintrust issued 1.0 million shares of its common stock, and received net proceeds of $55.9 million from Royal Bank of Canada.

     On August 16, 2005, Wintrust redeemed all 2,000,000 shares of the 10.50% Cumulative Trust Preferred Securities issued by Wintrust Capital Trust II at a redemption price equal to the $10.00 liquidation amount, plus accrued and unpaid distributions to the Redemption Date, for each Trust Preferred Security. The redemption of the Trust Preferred Securities was the result of the concurrent redemption by Wintrust of its 10.50% Junior Subordinated Debentures due 2030, all of which were held by the Wintrust Capital Trust II. The redemption was funded by the issuance of $40.0 million of trust preferred securities in a private placement to an institutional investor on August 2, 2005, by Wintrust’s newly formed wholly-owned special purpose finance subsidiary, Wintrust Capital Trust VIII, a Delaware statutory trust. This effectively replaced 10.50% fixed rate funding with funding equal to the three-month LIBOR rate plus 1.45% (initially priced at 5.15%). Subsequent to the issuance of this instrument, the Company entered into an interest rate swap that effectively fixed the rate at 5.27%.

De Novo Locations

     Over the past 12 months, Wintrust had the followingde novobanking location activity:

— Lake Bluff, Illinois (drive-through location of Lake Forest Bank & Trust Company) — opened third quarter of 2005

— The Sauganash neighborhood of Chicago (North Shore Community Bank & Trust — Sauganash, a branch of North Shore Community Bank & Trust) — opened fourth quarter 2004

Financial Performance Overview

     For the third quarter of 2005, net interest income totaled $56.1 million, increasing $17.0 million, or 43%, compared to the third quarter of 2004 and $2.2 million, or 16% on an annualized basis, over the second quarter of 2005. For the first nine months of 2005, net interest income totaled $159.9 million, increasing $47.6 million, or 42%, compared to the first nine months of 2004. Average earning assets grew $2.12 billion over the third quarter of 2004, a 43% increase. Loans accounted for $1.48 billion and liquidity management assets accounted for $668 million of the total average earning asset growth compared to the third quarter of 2004.

     The provision for loan losses totaled $3.1 million for the third quarter of 2005 compared to $1.3 million for the third quarter of 2004. On a year-to-date basis, the provision for loan losses totaled $5.6 million for the first nine months of 2005 compared to $5.0 million for the first nine months of 2004. The increase in provision for loan losses, in the third quarter of 2005, is in line with the increase in net-charge offs.

     The net interest margin for the third quarter of 2005 was 3.18%, compared to 3.17% in the third quarter of 2004 and 3.19% in the second quarter of 2005. The net interest margin improved one basis point in the third quarter of 2005 compared to the third quarter of 2004 as the yield on earning assets increased by 73 basis points, the rate paid on interest-bearing liabilities increased by 75 basis points and the contribution from net free funds increased by three basis points. The earning asset yield improvement in the third quarter of 2005 compared to the third quarter of 2004 was primarily attributable to a 101 basis point increase in the yield on loans. The higher loan yield is reflective of the interest rate increases effected by the Federal Reserve Bank offset somewhat by continued competitive loan pricing pressures, including the pricing related to the premium finance receivables portfolio. The interest-bearing liability rate increase of 75 basis points was due to higher costs of retail deposits as rates have generally risen in the past 12 months, continued competitive pricing pressures on fixed-maturity

time deposits in most markets and the promotional pricing activities associated with opening additionalde novobranches and branches acquired through acquisition. Combined, these factors caused a slight decline in the third quarter 2005 net interest margin compared to the second quarter of 2005. Expansion of the net interest margin in the past two quarters has been hampered by the loan to deposit ratio falling to 83%, below the Company’s targeted range of 85% to 90%. The heavier reliance in both the third and second quarters of 2005 on lower yielding liquidity management assets has contributed to compressed net interest margin levels. Overall, the Company believes it is well positioned for expected future rate increases.

     Non-interest income totaled $25.4 million in the third quarter of 2005, increasing $3.9 million, or 18%, compared to the third quarter of 2004. The increase was primarily attributable to higher levels of mortgage banking revenue and higher levels of premium income from covered call options. On a year-to-date basis, non-interest income increased $10.3 million, or 17%, fueled primarily by a $7.3 million increase in mortgage banking revenues.

     Non-interest expense totaled $50.3 million in the third quarter of 2005, increasing $11.9 million, or 31%, over the third quarter of 2004. The net overhead ratio for the third quarter of 2005 was 1.27% compared to 1.25% for the third quarter of 2004. On a year-to-date basis, non-interest expense increased by $37.5 million, or 34%, over 2004. The net overhead ratio for 2005 on a year-to-date basis was 1.36% compared to 1.25% for 2004.

     Non-performing assets totaled $26.6 million, or 0.34% of total assets, at September 30, 2005, compared to $19.5 million, or 0.33% of total assets, at September 30, 2004 and $21.9 million, or 0.28% of total assets, at June 30, 2005. Net charge-offs as a percentage of average loans for the third quarter of 2005 were 16 basis points compared to five basis points in the third quarter of 2004. On a year-to-date basis, net loan charge-offs as a percentage of average loans were 11 basis points in 2005 and six basis points in 2004. Non-performing assets at September 30, 2005, remain at levels that the Company believes make monitoring and collection of the non-performing assets manageable.

SUPPLEMENTAL FINANCIAL MEASURES/RATIOS

The accounting and reporting polices 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), core net interest margin and the efficiency ratio. 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 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 also evaluates the net interest margin excluding the net interest expense associated with the Company’s Long-term debt – trust preferred securities (“Core Net Interest Margin”). Because these instruments are utilized by the Company primarily as capital instruments, management finds it useful to view the net interest margin excluding this expense and deems it to be a more meaningful view of the operational net interest margin of the Company.

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 is shown below:

Net interest income, which is the difference between interest income and fees on earning assets and interest expense on deposits and borrowings, is the major source of earnings for Wintrust. Tax-equivalent net interest income for the quarter ended September 30, 2005 totaled $56.4 million, an increase of $17.1 million, or 44%, as compared to the $39.3 million recorded in the same quarter of 2004. Average loans in the third quarter of 2005 increased $1.48 billion, or 39%, over the third quarter of 2004.

13

Net interest margin represents tax-equivalent net interest income as a percentage of the average earning assets during the period. For the third quarter of 2005 the net interest margin was 3.18%, an increase of one basis point when compared to the net interest margin of 3.17% in the prior year third quarter, and a one basis point decrease when compared to the net interest margin of 3.19% in the second quarter of 2005. The core net interest margin, which excludes the net interest expense related to Wintrust’s Long-term Debt – Trust Preferred Securities, was 3.39% for the third quarter of 2005, 3.32% for the third quarter of 2004 and 3.40% for the second quarter of 2005.

The net interest margin increase of one basis point in the third quarter of 2005 compared to the third quarter of 2004 resulted as the yield on earning assets increased by 73 basis points, the rate paid on interest-bearing liabilities increased by 75 basis points and the contribution from net free funds increased by three basis points. The earning asset yield increase was primarily attributable to a 101 basis point increase in the yield on loans. The higher loan yield is reflective of the interest rate increases effected by the Federal Reserve Bank offset somewhat by continued competitive loan pricing pressures, including the pricing related to the premium finance receivables portfolio. The interest-bearing liability rate increase of 75 basis points was due to higher costs of retail deposits as rates have generally risen in the past 12 months, continued competitive pricing pressures on fixed-maturity time deposits in most markets and the promotional pricing activities associated with opening additional de novo branches and branches acquired through acquisition. Combined, these factors caused a slight decline in the third quarter 2005 net interest margin compared to the second quarter of 2005. Overall, the Company believes it is well positioned for expected future rate increases.

The yield on total earning assets for the third quarter of 2005 was 6.01% as compared to 5.28% in the third quarter of 2004. The increase of 73 basis points from the third quarter of 2004 resulted primarily from the rising interest rate environment in the last 15 months offset by the effects of a flattening yield curve. The third quarter 2005 yield on loans was 6.70%, a 101 basis point increase when compared to the prior year third quarter yield of 5.69%. Compared to the second quarter of 2005, the yield on earning assets increased 19 basis points primarily as a result of a 29 basis point increase in the yield on total loans, offset by a 14 basis point decline in the yield on liquidity management assets. The liquidity management asset yield decline was attributable to higher levels of lower yielding short-term investments.

The average loan to average deposit ratio was 83.3% in the third quarter of 2005, 87.0% in the third quarter of 2004 and 82.8% in the second quarter of 2005. Expansion of the net interest margin in the past two quarters has been hampered by the loan to deposit ratio falling below the Company’s targeted range of 85% to 90% as deposit growth at recently openedde novobranches was very strong and loan originations were slightly slower than expected as the Company chooses not to compromise on underwriting standards when competing for loan balances. Management believes loan growth will continue to be strong however, this growth will occur in a safe and sound manner. The heavier reliance in both the third and second quarters of 2005 on lower yielding liquidity management assets has contributed to the slightly lower net interest margin levels. Additionally, during the third quarter of 2005, the brokerage customer receivables component of other earning assets ceased being an asset of the Company’s broker dealer subsidiary as a result of the conversion to an out-sourced securities clearing platform. This asset typically had a higher yield than total liquidity management assets. This restricted net interest margin improvement in the third quarter of 2005 as well.

The rate paid on interest-bearing deposits increased to 2.90% in the third quarter of 2005 as compared to 2.12% in the third quarter of 2004. The rate paid on wholesale funding, consisting of Federal Home Loan Bank of Chicago advances, notes payable, subordinated notes, other borrowings and trust preferred securities, increased to 4.50% in the third quarter of 2005 compared to 3.89% in the third quarter of 2004 as a result of higher overnight funding costs, the additional trust preferred borrowings added in 2004 and the acceleration of the unamortized issuance costs related to the Company’s redeemed 10.50% Cumulative Trust Preferred Securities. The Company utilizes certain borrowing sources to fund the additional capital requirements of the subsidiary banks, manage its capital, manage its interest rate risk position and for general corporate purposes.

(1)	Liquidity management assets include available-for-sale securities, interest earning deposits with banks, federal funds sold and securities purchased under resale agreements.
(2)	Interest income on tax-advantaged loans, trading account securities and securities reflects a tax-equivalent adjustment based on a marginal federal corporate tax rate of 35%. The total adjustments for the nine months ended September 30, 2005 was $997,000 and for the nine months ended September 30, 2004 was $542,000.
(3)	Other earning assets include brokerage customer receivables and trading account securities.
(4)	Loans, net of unearned income, include mortgages held-for-sale and non-accrual loans.
(5)	Interest rate spread is the difference between the yield earned on earning assets and the rate paid on interest-bearing liabilities.
(6)	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.
(7)	The core net interest margin excludes the effect of the net interest expense associated with Wintrust’s Long-term Debt – Trust Preferred Securities.
(8)	See “Supplemental Financial Measures/Ratios” for additional information on this performance measure/ratio.

Tax-equivalent net interest income for the nine-months ended September 30, 2005 totaled $160.9 million, an increase of $48.0 million, or 43%, as compared to the $112.9 million recorded in the same period of 2004. The year-to-date net interest margin was 3.19%, an increase of three basis points when compared to the net interest margin of 3.16% in the prior year. The net interest margin increase of three basis points in the first nine months of 2005 compared to the first nine months of 2004 resulted as the yield on earning assets increased by 64 basis points, the rate paid on interest-bearing liabilities increased by 62 basis points and the contribution from net free funds increased by one basis point.

NON-INTEREST INCOME

For the third quarter of 2005, non-interest income totaled $25.4 million and increased $3.9 million compared to the prior year third quarter. The increase in non-interest income is primarily a result of higher mortgage banking revenue, higher levels of fees on covered call transactions and the impact of the recent acquisitions offset by lower wealth management fees, lower gain on sales of premium finance receivables and lower net available-for-sale securities gains. Non-interest income as a percentage of net revenue was 31% in the third quarter of 2005 and 35% in the third quarter of 2004. The Company uses this as a measuring stick as it works towards balancing the mix of net interest income and non-interest income. The impact of the four community bank acquisitions in the last 12 months has reduced this ratio as their revenue mix is more heavily weighted towards net interest income.

The following table presents non-interest income by category for the three months ended September 30, 2005 and 2004:

	Three Months Ended

Wealth management fees are comprised of the trust and asset management revenue of Wayne Hummer Trust Company and the asset management fees, brokerage commissions, trading commissions and insurance product commissions at Wayne Hummer Investments, Wayne Hummer Asset Management Company and Focused Investments. Wealth management fees totaled $7.0 million in the third quarter of 2005, a $213,000 decrease from the $7.2 million recorded in the third quarter of 2004 and an $867,000 decrease from the $7.8 million recorded in the second quarter of 2005. Revenue from retail brokerage trading in the debt and equity markets declined $530,000 when compared to the third quarter of 2004. The conversion to an out-sourced securities clearing platform in the third quarter of 2005 temporarily impacted the operations of Wayne Hummer Investments. The impact was felt before, during and after the conversion period through lower trading volumes, restricted levels of new customer acquisitions and restricted efforts to recruit new brokers. The Company anticipates recognizing the revenue enhancement capabilities and cost saving opportunities of this new platform in future periods.

Mortgage banking revenue includes revenue from activities related to originating and selling residential real estate loans into the secondary market. With the addition of WestAmerica and Guardian in May of 2004, this revenue line now includes gains on the sale of mortgage loans to the secondary market, origination fees, rate lock commitment fees, document preparation fees, the impact of capitalizing servicing rights on loans sold and serviced by certain Wintrust subsidiary banks, the impact of amortizing and valuing the capitalized servicing right asset and the impact of valuing mortgage banking derivatives as required by FAS133. For the quarter ended September 30, 2005, this revenue source totaled $7.8 million, an increase of $2.5 million compared to the third quarter of 2004. Mortgage banking revenue will continue to be dependent upon the relative level of long-term interest rates.

16

Service charges on deposit accounts totaled $1.5 million for the third quarter of 2005, an increase of $520,000, or 52%, when compared to the same quarter of 2004. This increase was primarily due to the impact of the bank acquisitions in 2004 and 2005. The majority of deposit service charges relates to customary fees on overdrawn accounts and returned items. The level of service charges received is substantially below peer group levels, as management believes in the philosophy of providing high quality service without encumbering that service with numerous activity charges.

Wintrust sold premium finance receivables to an unrelated third party financial institution in the third quarter of 2005 and recognized gains of $1.6 million related to this activity, compared with $1.8 million of recognized gains in the third quarter of 2004. It is probable that similar sales of premium finance receivables will occur in the future.

The administrative services revenue contributed by Tricom added $1.2 million to total non-interest income in the third quarter of 2005, an increase of $129,000 from the third quarter of 2004. This revenue comprises income from administrative services, such as data processing of payrolls, billing and cash management services, to temporary staffing service clients located throughout the United States. Tricom also earns interest and fee income from providing short-term accounts receivable financing to this same client base, which is included in the net interest income category.

Other non-interest income for the third quarter of 2005 totaled $6.3 million compared to $4.2 million in the third quarter of 2004. Premium income from certain covered call transactions totaled $4.0 million in the third quarter of 2005 compared to $2.7 million in the same period of 2004. Management is able to effectively use the proceeds from selling covered call options to offset net interest margin compression and administers such sales in a coordinated process with the Company’s overall asset/liability management.

The following table presents non-interest income by category for the nine months ended September 30, 2005 and 2004:

	Nine Months Ended
	September 30,				$			%

Total non-interest income	$	71,960	$	61,628		10,332			16.8

On a year-to-date basis, non-interest income totaled $72.0 million and increased $10.3 million compared to the prior year. The increase in non-interest income is primarily a result of increased revenue from mortgage banking activities, premium income from certain covered call transactions and the additional non-interest income added by the recent acquisitions. Revenue recognized from mortgage banking activities increased $7.3 million on a year-to-date basis primarily due to the impact of acquisitions of WAMC and Guardian. Service charges on deposit accounts increased $1.5 million primarily due to the acquisitions of Northview, Town, Antioch and FNBI. These increases helped offset a decline in wealth management fees of $948,000.

17

NON-INTEREST EXPENSE

Non-interest expense for the third quarter of 2005 totaled $50.3 million and increased $11.8 million, or 31%, from the third quarter 2004 total of $38.5 million. All categories of non-interest expense increased as a result of the acquisitions completed in 2004 and 2005.

Salaries and employee benefits totaled $29.5 million for the third quarter of 2005, an increase of $5.7 million, or 24%, as compared to the prior year’s third quarter total of $23.8 million. Occupancy expense increased as a result of opening four new banking locations during the past twelve months as part of the Company’sde novobanking strategy and adding 13 new locations as a result of the four bank acquisitions.

The provision for loan losses totaled $3.1 million for the third quarter of 2005 compared to $1.3 million for the third quarter of 2004. On a year-to-date basis, the provision for loan losses totaled $5.6 million for the first nine months of 2005 compared to $5.0 million for the first nine months of 2004. For the quarter ended September 30, 2005, net charge-offs totaled $2.2 million, up from the $475,000 of net charge-offs recorded in the same period of 2004. On a year-to-date basis, net charge-offs totaled $4.0 million, up from the $1.7 million of net charge-offs recorded in the same period of 2004. On a ratio basis, annualized net charge-offs as a percentage of average loans increased to 0.16% in the third quarter of 2005 from 0.05% in the same period in 2004. On a year-to-date basis, net loan charge-offs as a percentage of average loans were 0.11% in 2005 and 0.06% in 2004.

Management believes the allowance for loan losses is adequate 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 loan losses will be dependent upon management’s assessment of the adequacy 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.

Non-performing Residential Real Estate and Home Equity

The non-performing residential real estate and home equity loans totaled $1.8 million at September 30, 2005. The balance increased $770,000 from September 30, 2004 and $670,000 from June 30, 2005. Each non-performing credit is well secured and in the process of collection. Management believes that the current reserves against these credits are appropriate to cover any potential losses.

Non-performing Commercial, Consumer and Other

The commercial, consumer and other non-performing loan category totaled $13.5 million as of September 30, 2005. The balance in this category increased $7.4 million from September 30, 2004 and $2.5 million from June 30, 2005. Management believes that the current reserves against these credits are appropriate to cover any potential losses on any of the relatively small number of credits in this category.

Non-performing Premium Finance Receivables

The table below presents the level of non-performing premium finance receivables as of September 30, 2005, June 30, 2005 and September 30, 2004, and the amount of net charge-offs for the quarters then ended.

	September 30,			June 30,			September 30,
(Dollars in thousands)	2005			2005			2004
Non-performing premium finance receivables	$	9,009		$	9,370		$	10,252
- as a percent of premium finance receivables outstanding		1.13	%		1.18	%		1.34	%
Net charge-offs of premium finance receivables for the quarter	$	568		$	244		$	280
- annualized as a percent of average premium finance receivables		0.26	%		0.12	%		0.13	%

The level of non-performing premium finance receivables as a percent of total premium finance receivables improved from the levels reported at September 30, 2004 and June 30, 2005. As noted below, fluctuations in this category may occur due to the timing and nature of account collections from insurance carriers. Management is comfortable with administering the collections at this level of non-performing premium finance receivables and expects that such ratios will remain at relatively low levels.

The ratio of non-performing premium finance receivables fluctuates throughout the year due to the nature and timing of canceled account collections from insurance carriers. Due to the nature of collateral for premium finance receivables, it customarily takes 60-150 days to convert the collateral into cash collections. Accordingly, the level of non-performing 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.

21

Non-performing Indirect Consumer Loans

Total non-performing indirect consumer loans were $682,000 at September 30, 2005, compared to $457,000 at September 30, 2004 and $403,000 at June 30, 2005. The ratio of these non-performing loans to total indirect consumer loans was 0.34% at September 30, 2005 compared to 0.26% at September 30, 2004 and 0.21% at June 30, 2005. As noted in the Allowance for Loan Losses table, net charge-offs as a percent of total indirect consumer loans were 0.19% for the quarter ended September 30, 2005 compared to 0.13% in the same period in 2004. The level of non-performing and net charge-offs of indirect consumer loans continue to be below standard industry ratios for this type of lending.
