Notes to Condensed Consolidated Financial Statements (Unaudited)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies used by Enterprise Financial Services Corp (the “Company” or “Enterprise”) in the preparation of the condensed consolidated financial statements are summarized below:

Business and Consolidation

Enterprise is a financial holding company that provides a full range of banking and wealth management services to individuals and corporate customers located in the St. Louis, Kansas City and Phoenix metropolitan markets through its banking subsidiary, Enterprise Bank & Trust (the “Bank”).

Operating results for the three months ended March 31, 2012 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2012. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

Basis of Financial Statement Presentation

The condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all information and footnotes required by U.S. GAAP for annual financial statements. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain 2011 amounts in the consolidated financial statements have been reclassified to conform to the 2012 presentation. These reclassifications have no effect on Net income or Shareholders' equity as previously reported.

NOTE 2 - EARNINGS PER SHARE

Basic earnings per common share data is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method for convertible securities related to the issuance of trust preferred securities.

6

The following table presents a summary of per common share data and amounts for the periods indicated.

	Three months ended March 31,
(in thousands, except per share data)	2012			2011
Net income as reported	$	6,185		$	4,112
Preferred stock dividend	(438		)	(438		)
Accretion of preferred stock discount	(203		)	(188		)
Net income available to common shareholders	$	5,544		$	3,486
Impact of assumed conversions
Interest on 9% convertible trust preferred securities, net of income tax	371			—
Net income available to common shareholders and assumed conversions	$	5,915		$	3,486
Weighted average common shares outstanding	17,790			14,920
Incremental shares from assumed conversions of convertible trust preferred securities	1,439			—
Additional dilutive common stock equivalents	14			16
Diluted common shares outstanding	19,243			14,936
Basic earnings per common share:	$	0.31		$	0.23
Diluted earnings per common share:	$	0.31		$	0.23

There were 1.0 million common stock equivalents (including 324,074 common stock warrants) for the three months ended March 31, 2012, and 2.4 million common stock equivalents (including 324,074 common stock warrants) for the three months ended March 31, 2011 which were excluded from the earnings per share calculations because their effect was anti-dilutive.

NOTE 3 - INVESTMENTS

The following table presents the amortized cost, gross unrealized gains and losses and fair value of securities available-for-sale:

	March 31, 2012
(in thousands)	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
Available for sale securities:
Obligations of U.S. Government sponsored enterprises	$	74,105	$	712	$	—		$	74,817
Obligations of states and political subdivisions	38,883		1,632		(395		)	40,120
Residential mortgage-backed securities	386,150		5,979		(261		)	391,868
	$	499,138	$	8,323	$	(656	)	$	506,805
	December 31, 2011
(in thousands)	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
Available for sale securities:
Obligations of U.S. Government sponsored enterprises	$	126,305	$	678	$	(66	)	$	126,917
Obligations of states and political subdivisions	38,489		1,729		(381		)	39,837
Residential mortgage-backed securities	422,761		5,269		(1,602		)	426,428
	$	587,555	$	7,676	$	(2,049	)	$	593,182

At March 31, 2012, and December 31, 2011, there were no holdings of securities of any one issuer in an amount greater than 10% of shareholders’ equity, other than the U.S. government agencies and sponsored enterprises. The residential mortgage-backed securities are all issued by U.S. government sponsored enterprises. Available for sale securities having a carrying value of $225.7 million and $287.8 million at March 31, 2012, and December 31, 2011, respectively, were pledged as collateral to secure deposits of public institutions and for other purposes as required by law or contract provisions.

The amortized cost and estimated fair value of debt securities classified as available for sale at March 31, 2012, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. The weighted average life of the mortgage-backed securities is approximately 4 years.

(in thousands)	Amortized Cost		Estimated Fair Value
Due in one year or less	$	1,329	$	1,348
Due after one year through five years	51,651		52,407
Due after five years through ten years	55,624		56,986
Due after ten years	4,384		4,196
Mortgage-backed securities	386,150		391,868
	$	499,138	$	506,805

The following table represents a summary of available-for-sale investment securities that had an unrealized loss:

	March 31, 2012
	Less than 12 months				12 months or more				Total
(in thousands)	Fair Value		Unrealized Losses		Fair Value		Unrealized Losses		Fair Value		Unrealized Losses
Obligations of the state and political subdivisions	$	1,498	$	19	$	3,024	$	376	$	4,522	$	395
Residential mortgage-backed securities	78,492		261		—		—		78,492		261
	$	79,990	$	280	$	3,024	$	376	$	83,014	$	656
	December 31, 2011
	Less than 12 months				12 months or more				Total
(in thousands)	Fair Value		Unrealized Losses		Fair Value		Unrealized Losses		Fair Value		Unrealized Losses
Obligations of U.S. government sponsored enterprises	$	23,389	$	66	$	—	$	—	$	23,389	$	66
Obligations of the state and political subdivisions	1,503		8		3,027		373		4,530		381
Residential mortgage-backed securities	86,954		1,598		4,203		4		91,157		1,602
	$	111,846	$	1,672	$	7,230	$	377	$	119,076	$	2,049

The unrealized losses at both March 31, 2012, and December 31, 2011, were attributable to changes in market interest rates since the securities were purchased. Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security and (5) the intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value. At March 31, 2012, management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired.

The gross gains and gross losses realized from sales of available-for-sale investment securities were as follows:

	Three months ended March 31,
(in thousands)	2012			2011
Gross gains realized	$	1,075		$	174
Gross losses realized	(53		)	—
Proceeds from sales	64,476			5,299

The Company grants commercial, residential, and consumer loans primarily in the St. Louis, Kansas City and Phoenix metropolitan areas. The Company has a diversified loan portfolio, with no particular concentration of credit in any one economic sector; however, a substantial portion of the portfolio is concentrated in and secured by real estate. The ability of the Company’s borrowers to honor their contractual obligations is partially dependent upon the local economy and its effect on the real estate market.

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, and current economic factors among other factors. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings:

• Grades 1, 2, and 3 - These grades include loans to borrowers with a continuous record of strong earnings, sound balance sheet condition and capitalization, ample liquidity with solid cash flow and whose management team has experience and depth within their industry.

• Grade 4 – This grade includes loans to borrowers with positive trends in profitability, satisfactory capitalization and balance sheet condition, and sufficient liquidity and cash flow.

• Grade 5 – This grade includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization, liquidity, and cash flow.

• Grade 6 – This grade includes loans to borrowers where an adverse change or perceived weakness has occurred, but may be correctable in the near future. Alternatively, this rating category may also include circumstances where the company is starting to reverse a negative trend or condition, or have recently been upgraded from a 7, 8, or 9 rating.

• Grade 7 – Watch credits are companies that have experienced financial setback of a nature that are not determined to be severe or influence ‘ongoing concern’ expectations. Borrowers within this category are expected to turnaround within a 12-month period of time. Although possible, no loss is anticipated, due to strong collateral and/or guarantor support.

15

• Grade 8 – Substandard credits will include those companies that are characterized by significant losses and sustained downward trends in balance sheet condition, liquidity, and cash flow. Repayment reliance may have shifted to secondary sources. Collateral exposure may exist and additional reserves may be warranted.

• Grade 9 – Doubtful credits include borrowers that may show deteriorating trends that are unlikely to be corrected. Collateral values may appear insufficient for full recovery, therefore requiring a partial charge-off, or debt renegotiation with the borrower. Borrower may have declared bankruptcy or bankruptcy is likely in the near term. All doubtful rated credits will be on non-accrual.

NOTE 6 - PORTFOLIO LOANS COVERED BY LOSS SHARE ("Covered loans")

Purchased loans acquired in a business combination, including loans purchased in our FDIC-assisted transactions, are recorded at estimated fair value on their purchase date without a carryover of the related allowance for loan losses. Purchased credit-impaired loans are loans that have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments. Evidence of credit quality deterioration as of the purchase date may include factors such as past due and non-accrual status. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable yield. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges or a reclassification of the difference from non-accretable to accretable with a positive impact on interest income, prospectively. Further, any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan when there is a reasonable expectation about the amount and timing of such cash flows. Acquired loans that have common risk characteristics are aggregated into pools. The Company remeasures contractual and expected cash flows, at the pool-level, on a quarterly basis.

16

Inputs to the determination of expected cash flows include contractual cash flows, cumulative default and prepayment data as well as loss severity and recovery lag information. Cumulative default and prepayment data are calculated via a transition matrix. The transition matrix is a matrix of probability values that specifies the probability of a loan pool transitioning into a loss given its delinquency state (e.g. 0-30 days past due, 31 to 60 days, etc.) at the remeasurement date. Loss severity factors are based upon industry data along with actual charge-off data within the loan pools and recovery lags are based upon industry data along with experience with the collateral within the loan pools.

Covered loans are also subject to the Company’s internal and external credit review and are risk rated using the same criteria as loans originated by the Company. However, risk ratings are not always a clear indicator of the Company's losses on acquired loans as a majority of the losses are recoverable from the FDIC under the loss-sharing agreements.

NOTE 7 - COMMITMENTS AND CONTINGENCIES

The Company issues financial instruments with off balance sheet risk in the normal course of the business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets.

The Company’s extent of involvement and maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments.

The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. At March 31, 2012, there were $1.1 million of unadvanced commitments on impaired loans. Other liabilities include approximately $212,000 for estimated losses attributable to the unadvanced commitments on impaired loans.

The contractual amounts of off-balance-sheet financial instruments as of March 31, 2012, and December 31, 2011, are as follows:

(in thousands)	March 31, 2012		December 31, 2011
Commitments to extend credit	$	603,935	$	547,657
Standby letters of credit	46,259		43,973

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments usually have fixed expiration dates or other termination clauses and may require payment of a fee. Of the total commitments to extend credit at March 31, 2012, and December 31, 2011, approximately $61.8 million and $75.7 million, respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These standby letters of credit are issued to support contractual obligations of the Company’s customers. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. The approximate remaining term of standby letters of credit range from 6 months to 5 years at March 31, 2012.

Contingencies

The Company and its subsidiaries are, from time to time, parties to various legal proceedings arising out of their businesses. Other than those described below, management believes that there are no such proceedings pending or threatened against the Company or its subsidiaries which, if determined adversely, would have a material adverse effect on the business, consolidated financial condition, results of operations or cash flows of the Company or any of its subsidiaries.

Distinctive Notes

The Bank, along with other co-defendants has been named as a defendant in two lawsuits filed by persons alleging to be clients of the Bank’s Trust division who invested in promissory notes (the "Distinctive Notes") issued by Distinctive Properties (UK) Limited (“Distinctive Properties”), a company involved in the purchase and development of real estate in the United Kingdom. The Company is unable to estimate a reasonably possible loss for the cases described below

19

because the proceedings are in early stages and there are significant factual issues to be determined and resolved in each case. The Company denies plaintiffs’ allegations and intends to vigorously defend the lawsuits.

Rosemann, et al. v. Martin Sigillito, et al. 

In one of the lawsuits, the plaintiffs allege that the investments in the Distinctive Notes were part of a multi-million dollar Ponzi scheme. Plaintiffs allege to hold such promissory notes in accounts with the Trust division and that, among other things, the Bank was negligent, breached its fiduciary duties and breached its contracts. Plaintiffs also allege that the Bank violated the Racketeer Influenced and Corrupt Organizations Act (“RICO”). Plaintiffs, in the aggregate, are seeking damages from defendants, including the Bank, in excess of $25.0 million as well as their costs and attorneys’ fees and trebled damages under RICO.

As previously reported, on July 1, 2011, the United States moved to intervene in the case for purposes of securing a stay of the case pending completion of it's criminal case against the individual defendants, and did not include the Company, the Bank or any affiliates thereof.

BJD, LLC and Barbara Dunning v. Enterprise Bank & Trust, et. al.

The Bank has also been named as a defendant in this case, relating to BJD’s investment in the Distinctive Notes. Plaintiffs allege that the Bank, and the other defendants breached their fiduciary duties and were negligent in allowing plaintiffs to invest in the Distinctive Notes because the loan program was allegedly never funded and the assets of the borrower did not exist or were overvalued. Plaintiffs are seeking approximately $800,000 in damages, 9% interest, punitive damages, attorneys’ fees and costs.

On July 11, 2011, the U.S. Attorney's Office moved to intervene in this case as well for purposes of seeking a stay of certain discovery pending completion of the above described criminal proceedings. As a result, certain discovery in the case was put on hold for the duration of such criminal proceedings.

The criminal proceedings against Sigillito began on March 19, 2012. After a four week trial, Sigillito was found guilty of 20 counts of wire fraud, mail fraud, conspiracy and money laundering. Following this verdict, the judge lifted the stay and has scheduled a Rule 16 conference in the Rosemann case for May 31, 2012. The court in the Dunning case has granted the Bank's motion to compel arbitration and stay proceedings and scheduled a case management conference for May 10, 2012.

William Mark Scott v. Enterprise Financial Services Corp, et. al.

On April 10, 2012, a putative class action was filed in the United States District Court for the Eastern District of Missouri captioned William Mark Scott v. Enterprise Financial Services Corp, Peter F. Benoist, and Frank H. Sanfilippo. The complaint asserts claims for violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on behalf of a putative class of purchasers of the Company's stock between April 20, 2010 and January 25, 2012, inclusive. The complaint alleges, among other things, that defendants made false and misleading statements and "failed to disclose that the Company was improperly recording income on loans covered under loss share agreements with the FDIC" and that, as a result, "the Company's financial statements were materially false and misleading at all relevant times." The action seeks unspecified damages and costs and expenses. The Company is unable to estimate a reasonably possible loss for the case because the proceeding is in an early stage and there are significant factual issues to be determined and resolved. The Company denies plaintiffs’ allegations and intends to vigorously defend the lawsuit.

NOTE 8 - DERIVATIVE FINANCIAL INSTRUMENTS

The Company is a party to various derivative financial instruments that are used in the normal course of business to meet the needs of its clients and as part of its risk management activities. These instruments include interest rate swaps and option contracts. The Company does not enter into derivative financial instruments for trading or speculative purposes.

20

Interest rate swap contracts involve the exchange of fixed and floating rate interest payment obligations without the exchange of the underlying principal amounts. The Company enters into interest rate swap contracts on behalf of its

clients and also utilizes such contracts to reduce or eliminate the exposure to changes in the cash flows or fair value of hedged assets or liabilities due to changes in interest rates. Interest rate option contracts consist of caps and provide for the transfer or reduction of interest rate risk in exchange for a fee.

All derivative financial instruments, whether designated as hedges or not, are recorded on the consolidated balance sheet at fair value within Other assets or Other liabilities. The accounting for changes in the fair value of a derivative in the consolidated statement of operations depends on whether the contract has been designated as a hedge and qualifies for hedge accounting. At March 31, 2012, and December 31, 2011, the Company did not have any derivatives designated as cash flow or fair value hedges.

Using derivative instruments means assuming counterparty credit risk. Counterparty credit risk relates to the loss the Company could incur if a counterparty were to default on a derivative contract. Notional amounts of derivative financial instruments do not represent credit risk, and are not recorded in the consolidated balance sheet. They are used merely to express the volume of this activity. The overall credit risk and exposure to individual counterparties is monitored. The Company does not anticipate nonperformance by any counterparties. The amount of counterparty credit exposure is the unrealized gains, if any, on such derivative contracts. At March 31, 2012, the Company had $1.4 million of unrealized gains. At March 31, 2012, the Company had pledged cash of $2.9 million and at December 31, 2011, the Company had pledged cash of $2.7 million, as collateral in connection with our interest rate swap agreements.

Risk Management Instruments. The Company enters into certain derivative contracts to economically hedge state tax credits and certain loans.

• Economic hedge of state tax credits. In November 2008, the Company paid $2.1 million to enter into a series of interest rate caps in order to economically hedge changes in fair value of the State tax credits held for sale. In February 2010, the Company paid $751,000 for an additional series of interest rate caps. See Note 10—Fair Value Measurements for further discussion of the fair value of the state tax credits.

• Economic hedge of prime based loans. Previously, the Company had two outstanding interest rate swap agreements whereby the Company paid a variable rate of interest equivalent to the prime rate and received a fixed rate of interest. The swaps were designed to hedge the cash flows associated with a portion of prime based loans and had been designated as cash flow hedges. However, in December 2008, due to a variable rate differential, the Company concluded the cash flow hedges would not be prospectively effective and the hedges were dedesignated. The swaps were terminated in February 2009. The unrealized gain prior to dedesignation was included in Accumulated other comprehensive income and is being amortized over the expected life of the related loans. For the three months ended March 31, 2011, $44,000 was reclassified into Miscellaneous income. At December 31, 2011, there were no additional amounts remaining in Accumulated other comprehensive income to be reclassified into operations.

The table below summarizes the notional amounts and fair values of the derivative instruments used to manage risk.

NOTE 9 - COMPENSATION PLANS

The Company maintains a number of share-based incentive programs, which are discussed in more detail in Note 16 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2011. There were no stock options, stock-settled stock appreciation rights, or restricted stock units granted in the first three months of 2012. The share-based compensation expense was $473,000 and $545,000 for the three months ended March 31, 2012 and 2011, respectively.

Stock Plan for Non-Management Directors

Shares are issued twice a year and compensation expense is recorded as the shares are earned, therefore, there is no unrecognized compensation expense related to this plan. The Company recognized $162,000 and $167,000 of share-based compensation expense for the directors for the three months ended March 31, 2012 and 2011, respectively. Pursuant to this plan, the Company issued 11,148 and 13,900 shares in the first three months of 2012 and 2011, respectively.

Employee Stock Issuance

Restricted stock was issued to certain key employees as part of their compensation. The restricted stock may be in a form of a one-time award or paid in pro rata installments. The stock is restricted for at least 2 years and upon issuance may be fully vested or vest over five years. The Company recognized $19,000 and $5,000 of share-based compensation expense related to these awards for the three months ended March 31, 2012 and 2011, respectively and issued 10,501 and 4,831 shares in the three months ended March 31, 2012 and 2011, respectively.

23

In conjunction with the Company’s short-term incentive plan, the Company issued 0 and 14,329 restricted shares to certain key employees in the three months ended March 31, 2012 and 2011, respectively. The compensation expense related to these shares was expensed in 2011. For further information on the short-term incentive plan, refer to the Compensation Discussion and Analysis in the Company’s Proxy Statement for the 2012 Annual Meeting of Stockholders.

Moneta Plan

• Securities available for sale. Securities classified as available for sale are reported at fair value utilizing Level 2 and Level 3 inputs. The Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions. At March 31, 2012, Level 3 securities available for sale include three Auction Rate Securities and a municipal bond issued by a school district.

• Portfolio Loans. Certain fixed rate portfolio loans are accounted for as trading instruments and reported at fair value. Fair value on these loans is determined using a third party valuation model with observable Level 2 market data inputs.

• State tax credits held for sale. At March 31, 2012, of the $48.2 million of state tax credits held for sale on the condensed consolidated balance sheet, approximately $24.7 million were carried at fair value. The remaining $23.5 million of state tax credits were accounted for at cost.

The fair value of the state tax credits carried at fair value decreased $283,000 for the quarter ended March 31, 2012 compared to $164,000 for the same period in 2011. These fair value changes are included in Gain on State tax credits, net in the condensed consolidated statements of operations.

The Company is not aware of an active market that exists for the 10-year streams of state tax credit financial instruments. However, the Company’s principal market for these tax credits consists of Missouri state residents who buy these credits and from local and regional accounting firms who broker them. As such, the Company employed a discounted cash flow analysis (income approach) to determine the fair value.

The fair value measurement is calculated using an internal valuation model with observable market data including discounted cash flows based upon the terms and conditions of the tax credits. Assuming that the underlying project remains in compliance with the various federal and state rules governing the tax credit program, each project will generate about 10 years of tax credits. The inputs to the fair value calculation include: the amount of tax credits generated each year, the anticipated sale price of the tax credit, the timing of the sale and a discount rate. The discount rate is defined as the LIBOR swap curve at a point equal to the remaining life in years of credits plus a 205 basis point spread. With the exception of the discount rate, the other inputs to the fair value calculation are observable and readily available. The discount rate is considered a Level 3 input because it is an “unobservable input” and is based on the Company’s assumptions. An increase in the discount rate utilized would generally result in a lower estimated fair value of the tax credits. Alternatively, a decrease in the discount rate utilized would generally result in a higher estimated fair value of the tax credits. Given the significance of this input to the fair value calculation, the state tax credit assets are reported as Level 3 assets.

• Derivatives. Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains counterparty quotations to value its interest rate swaps and caps. In addition, the Company validates the counterparty quotations with third party valuation sources. Derivatives with negative fair values are included in Other liabilities in the consolidated balance sheets. Derivatives with positive fair value are included in Other assets in the consolidated balance sheets.

Level 3 financial instruments

The following table presents the changes in Level 3 financial instruments measured at fair value on a recurring basis as of March 31, 2012.

• Purchases, sales, issuances and settlements, net. There were no Level 3 purchases during the quarter ended March 31, 2012.

• Transfers in and/or out of Level 3. The transfer out of Level 3 is related to a newly issued mortgage-backed security purchased in the fourth quarter of 2011 which was originally priced using Level 3 assumptions. In the first quarter of 2012, a third party pricing service became available.

From time to time, the Company measures certain assets at fair value on a nonrecurring basis. These include assets that are measured at the lower of cost or fair value that were recognized at fair value below cost at the end of the period. The following table presents financial instruments and non-financial assets measured at fair value on a non-recurring basis as of March 31, 2012.

(1) The amounts represent only balances measured at fair value during the period and still held as of the reporting date.

Impaired loans are reported at the fair value of the underlying collateral. Fair values for impaired loans are obtained from current appraisals by qualified licensed appraisers or independent valuation specialists. Other real estate owned is adjusted to fair value upon foreclosure of the underlying loan. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value less costs to sell. Fair value of other real estate is based upon the current appraised values of the properties as determined by qualified licensed appraisers and the Company’s judgment of other relevant market conditions. Certain state tax credits are reported at cost.

Following is a summary of the carrying amounts and fair values of the Company’s financial instruments on the consolidated balance sheets at March 31, 2012, and December 31, 2011.

The Company has two primary operating segments, Banking and Wealth Management, which are delineated by the products and services that each segment offers. The segments are evaluated separately on their individual performance, as well as their contribution to the Company as a whole.

The Banking operating segment consists of a full-service commercial bank, with locations in St. Louis, Kansas City, and Phoenix. The majority of the Company’s assets and income result from the Banking segment. All banking locations have the same product and service offerings, have similar types and classes of customers and utilize similar service delivery methods. Pricing guidelines and operating policies for products and services are the same across all regions.

The Wealth Management segment includes the Trust division of the Bank and the state tax credit brokerage activities. The Trust division provides estate planning, investment management, and retirement planning as well as consulting on management compensation, strategic planning and management succession issues. State tax credits are part of a fee initiative designed to augment the Company’s wealth management segment and banking lines of business.

The Corporate segment’s principal activities include the direct ownership of the Company’s banking subsidiary and the issuance of debt and equity. Its principal source of liquidity is dividends from its subsidiaries and stock option exercises.

The financial information for each business segment reflects that information which is specifically identifiable or which is allocated based on an internal allocation method. There were no material intersegment revenues among the

28

three segments. Management periodically makes changes to methods of assigning costs and income to its business segments to better reflect operating results. When appropriate, these changes are reflected in prior year information presented below.

Following are the financial results for the Company’s operating segments.

Introduction

The following discussion describes the significant changes to the financial condition of the Company that have occurred during the first three months of 2012 compared to the financial condition as of December 31, 2011. In addition, this discussion summarizes the significant factors affecting the results of operations, liquidity and cash flows of the Company for the three months ended March 31, 2012, compared to the same periods in 2011. This discussion should be read in conjunction with the accompanying consolidated financial statements included in this report and our Annual Report on Form 10-K for the year ended December 31, 2011.

Executive Summary

The Company reported net income of $6.2 million for the three months ended March 31, 2012, compared to net income of $4.1 million for the same period in 2011. After deducting dividends on preferred stock, the Company reported net income per fully diluted share of $0.31, compared to net income of $0.23 per fully diluted share for the prior year period.

Below are highlights of our Banking and Wealth Management segments. For more information on our segments, see Note 11 –Segment Reporting.

Banking Segment

• Loans - Portfolio loans totaled $2.2 billion at March 31, 2012, including $269.2 million of loans covered under FDIC shared loss agreements ("Covered loans"). Covered loans decreased $31.4 million, or 10%, in the first quarter of 2012, due to loans that paid off and principal paydowns.

Excluding Covered loans, portfolio loans increased $20.5 million, or 1%, from December 31, 2011. Commercial & Industrial loans increased $28.9 million, or 4%, during the quarter. Commercial and Residential Real Estate decreased $17.9 million while Construction Real Estate increased $8.3 million.

For fiscal year 2012, the Company expects 6-8% growth in portfolio loans not covered by FDIC shared loss agreements, similar to 2011 results.

See Note 5 – Portfolio Loans not covered by loss share and Note 6 – Portfolio Loans covered by loss share for more information.

• Deposits – Total deposits at March 31, 2012 were $2.7 billion, a decrease of $87.2 million, or 3%, from December 31, 2011. It is not unusual to see some deposit runoff in the first quarter given our customer base.

Core deposits, exclude brokered certificates of deposit and include reciprocal CDARS deposits, decreased $62.1 million, or 2%, in the first quarter of 2012. Non CDARS certificates of deposit decreased $65.4 million, or 10%, consistent with our desire to lower our cost of funds, while demand deposits increased $6.7 million. Core deposits represented 96% of total deposits at March 31, 2012 compared to 95% at December 31, 2011.

30

Reciprocal CDARS certificates were reduced to $7.6 million at March 31, 2012 compared to $14.5 million at December 31, 2011 and $74.8 million at March 31, 2011. Brokered certificates of deposit were reduced to $101.6 million at March 31, 2012 compared to $126.6 million at December 31, 2011 and $156.7 million at March 31, 2011.

• Asset quality – Nonperforming loans, including troubled debt restructurings of $13.2 million, were $47.2 million at March 31, 2012, compared to $41.6 million at December 31, 2011 and $43.5 million at March 31, 2011. Nonperforming loans represented 2.46% of total loans excluding Covered loans at March 31, 2012 versus 2.19% at December 31, 2011 and 2.47% at March 31, 2011. Excluding non-accrual loans and Covered loans, portfolio loans that were 30-89 days delinquent at March 31, 2012 remained at low levels, representing 0.62% of the portfolio compared to 0.36% at December 31, 2011 and 0.14% at March 31, 2011.

Provision for loan losses not covered under FDIC loss share was $1.7 million in the first quarter of 2012, compared to $3.6 million in the first quarter of 2011. The decrease in the provision for loan losses in the first quarter of 2012 was due to lower levels of loan risk rating downgrades and better loss migration statistics from a year ago. See Note 5 – Portfolio Loans not covered by loss share and Provision and Allowance for Loan Losses and Nonperforming Assets in this section for more information.

• Interest rate margin – The net interest rate margin was 4.33% for the first quarter of 2012, compared to 4.35% for the fourth quarter of 2011 and 3.58% in the first quarter of 2011. See Net Interest Income in this section for more information.

• Covered loans and other assets covered under FDIC shared loss agreements - The following table illustrates the net revenue contribution of covered assets in the first quarter of 2012 and applicable prior year periods.

Wealth Management Segment

Fee income from the Wealth Management segment includes Wealth Management revenue and income from state tax credit brokerage activities. Wealth Management revenue was $1.7 million in the first quarter of 2012, an increase of $41,000, or 2%, over the linked fourth quarter and an increase of $26,000, or 2%, compared to March 31, 2011. See Noninterest Income in this section for more information.

Net Interest Income

Three months ended March 31, 2012 and 2011

Net interest income (on a tax equivalent basis) was $31.0 million for the three months ended March 31, 2012 compared to $23.0 million for the same period of 2011, an increase of $8.0 million, or 35%. Total interest income increased $6.7 million and total interest expense decreased $1.2 million.

Average interest-earning assets increased $267.1 million, or 10%, to $2.9 billion for the quarter ended March 31, 2012 from $2.6 billion for the quarter ended March 31, 2011. Average loans increased $221.6 million, or 11%, to $2.2 billion for the quarter ended March 31, 2012 from $2.0 billion for the quarter ended March 31, 2011. Approximately $126.0 million of the increase is related to the increase in the Non-covered loans. Average securities and short-term investments increased $45.5 million, or 7%, to $699.8 million from the first quarter of 2011 as increased core deposits, including demand deposits, could not be deployed in loans. Interest income on earning assets increased $5.3 million due to higher volume and $1.4 million due to higher rates, for an increase of $6.7 million versus the first quarter of 2011.

For the quarter ended March 31, 2012, average interest-bearing liabilities increased $160.5 million, or 7%, to $2.4 billion compared to $2.3 billion for the quarter ended March 31, 2011. The increase in average interest-bearing liabilities resulted from a $157.3 million increase in average interest-bearing deposits, due to a $221.9 million increase in average money market accounts and savings accounts, an increase of $49.5 million in interest-bearing transaction accounts, offset by a decrease of $114.1 million in certificates of deposit. For the first quarter of 2012, interest expense on interest-bearing liabilities decreased $1.3 million due to declining rates partially offset by an increase of $70,000 due to the impact of higher volumes, for a net decrease of $1.2 million versus the first quarter of 2011.

The tax-equivalent net interest rate margin was 4.33% for the first quarter of 2012, compared to 4.35% for the fourth quarter of 2011 and 3.58% in the first quarter of 2011. In the first quarter of 2012, the Covered loans yielded 14.24% primarily due to cash flows on paid off loans that exceeded expectations. Absent the Covered loans, and the related nonearning assets, the net interest rate margin was 3.45% for the first quarter of 2012 compared to 3.36% for the fourth quarter of 2011. The increase in the net interest rate margin, excluding the effects of related nonearning assets under FDIC loss share loans, and the related funding costs, was primarily due to better earning asset mix and slightly lower funding costs.

We expect the net interest margin to continue at 4% or more for 2012 based on a better earning asset mix, the full year impact of the The First National Bank of Olathe ("FNB") acquisition and continued discipline on funding costs. We expect continued volatility in the yield on Covered loans due primarily to prepayments, and possibly the quarterly remeasurement of cash flows.

Provision and Allowance for Loan Losses

The provision for loan losses not covered under FDIC loss share was $1.7 million in the first quarter of 2012 compared to $3.6 million in the first quarter of 2011. The lower loan loss provision in the first quarter of 2012 compared to the the first quarter of 2011 was due to lower levels of loan risk rating downgrades and better loss migration statistics from a year ago. For the full year 2012, we expect the provision for loan losses not covered under FDIC loss share to be approximately $13 to $14 million, essentially flat with 2011 results.

34

For Covered loans, the Company remeasures contractual and expected cash flows on a quarterly basis. When the remeasurement process results in a decrease in expected cash flows due to an increase in expected credit losses, impairment is recorded. The provision for loan losses on Covered loans was $2.3 million in the first quarter of 2012 compared to $0 in the first quarter of 2011.

Excluding the Covered loans, the allowance for loan losses was 1.96% of total loans at March 31, 2012, representing 80% of nonperforming loans. The loan loss allowance was 2.00% at December 31, 2011 representing 91% of nonperforming loans and 2.43% at March 31, 2011 representing 98% of nonperforming loans. Management believes that the allowance for loan losses is adequate to absorb inherent losses in the loan portfolio.

Excluding the Covered loans, net charge-offs in the first quarter of 2012 were $2.1 million, representing an annualized rate of 0.45% of average loans, compared to net charge-offs of $4.9 million, an annualized rate of 1.04% of average loans, in the fourth quarter of 2011 and $3.5 million, an annualized rate of 0.81% of average loans, in the first quarter of 2011. Approximately 33% of the net charge-offs in the first quarter of 2012 were related to Construction, Land Acquisition and Development loans, 23% were related to Commercial & Industrial, 43% were related to Commercial Real Estate loans, and 1% were related to Residential Real Estate loans and Consumer and other loans.

Given the continued softness in real estate values in our markets, in 2012 the Company expects net charge-offs (excluding Covered loans) of $15 to $20 million, consistent with 2011 results.

Nonperforming loans, including troubled debt restructurings of $13.2 million, were $47.2 million at March 31, 2012, an increase from $41.6 million at December 31, 2011 and $43.5 million at March 31, 2011. The nonperforming loans are comprised of approximately 45 relationships with the largest being a $4.6 million commercial real estate loan. Five relationships comprise 43% of the nonperforming loans. Approximately 40% of the nonperforming loans were located in the Kansas City market, 59% were located in the St. Louis market, and 1% were located in the Arizona market. At March 31, 2012, there were no performing restructured loans that have been excluded from the nonperforming loan amounts.

Nonperforming loans represented 2.46% of Non-covered loans at March 31, 2012, versus 2.19% at December 31, 2011 and 2.47% at March 31, 2011.

Other real estate

Other real estate at March 31, 2012, was $45.4 million, compared to $53.7 million at December 31, 2011, and $51.3 million at March 31, 2011. Approximately 57% of total Other real estate, or $25.7 million, is covered by one of four FDIC shared-loss agreements.

The following table summarizes the changes in Other real estate for the past five quarters.

38

At March 31, 2012, Other real estate was comprised of 13% residential lots, 8% completed homes, and 79% commercial real estate. Of the total Other real estate, 39%, or 41 properties, are located in the Kansas City region, 29%, or 17

properties, are located in the St. Louis region and 32%, or 32 properties, are located in the Arizona region. All Arizona Other real estate properties and 24 properties, or $11.2 million, of the Kansas City Other real estate are covered under FDIC loss share.

The writedowns in fair value were recorded in Loan legal and other real estate expense based on current market activity shown in the appraisals. In addition, for the three months ended March 31, 2012, the Company realized a net gain of $1.2 million on the sale of other real estate and recorded these gains as part of Noninterest income.

Noninterest Income

Noninterest income decreased $980,000, or 20%, in the first quarter of 2012 compared to the first quarter of 2011. The decrease is primarily due to decreases in income related to changes in the FDIC Receivable partially offset by increases in gains on the sale of investment securities and gains on the sale of other real estate.

• Wealth Management revenue– For the quarter ended March 31, 2012, Wealth Management revenue from the Trust division increased $26,000, or 2%, compared to the same period in 2011. Assets under administration were $1.7 billion at March 31, 2012, a 4% increase from March 31, 2011 due to market value increases and additional accounts from new and existing clients, including acquired Legacy and FNB Trust assets.

• Sale of Other real estate – For the quarter ended March 31, 2012, we sold $13.4 million of Other real estate for a gain of $1.2 million compared to $4.0 million of Other real estate for a net gain of $423,000 during the same period in 2011.

• State tax credit brokerage activities– For the quarter ended March 31, 2012, the Company recorded a gain of $337,000 compared to a gain of $155,000 in the first quarter of 2011. Gains of $646,000 related to the sale of state tax credits to clients were partially offset by a negative fair value adjustment of $283,000 and a negative fair value adjustment of $26,000 on the interest rate caps used to economically hedge the tax credits . See Note 8 – Derivatives Instruments and Hedging Activities above for more information on the interest rate caps. For more information on the fair value treatment of the state tax credits, see Note 10 – Fair Value Measurements.

• Sale of investment securities – During the first three months of 2012, the Company purchased approximately $10.2 million in securities primarily in residential mortage-backed securities and municipal securities. The Company sold approximately $64.5 million of securities realizing a gain of $1.0 million on these sales.

• Change in FDIC loss share receivable – Income related to changes in the FDIC loss share receivable decreased $3.7 million during the first quarter of 2012 compared to the same period in 2011. The decrease in income related to the FDIC loss share receivable was primarily due to loan pay offs in which the losses on the loans were less than expected along with lower loss expectations on certain loan pools. To correlate with the new projected loss amounts, the FDIC loss share receivable must be reduced. In 2012, absent any changes based on the results of the quarterly remeasurement process, the Company anticipates continued negative accretion as the FDIC loss share receivable is adjusted down for lower anticipated losses.

• Miscellaneous income – Miscellaneous income increased $425,000, or 116%, compared to the same period in 2011 primarily due to increases in fee income related to the allocation of New Market Tax Credits to developers and projects and increases in gains on the sale of mortgages.

39

Noninterest Expense

Noninterest expenses were $21.4 million in the first quarter of 2012, an increase of $3.4 million, or 19%, from the same quarter of 2011. The increase over the prior year period was primarily comprised of an increase of $1.8 million in salaries and benefits, a $601,000 increase in legal and professional fees and a $355,000 increase in amortization of intangibles primarily due to our Kansas City acquisition activity.

The Company's efficiency ratio, which measures noninterest expense as a percentage of total revenue, was 62% for the quarter ended March 31, 2012 compared to 65% for the prior year period.

In 2012, the Company expects noninterest expenses to average $20 to $22 million per quarter as loan collection expenses on Covered assets remain elevated and the full year impact of compensation expense for the FNB acquisition and expenses for other new initiatives are realized.

Income Taxes

For the quarter ended March 31, 2012, the Company’s income tax expense, which includes both federal and state taxes, was $3.1 million compared to $2.0 million for the same period in 2011. The combined federal and state effective income tax rates were 33.1% and 32.7% for the quarters ended March 31, 2012, and 2011, respectively.

A valuation allowance is provided on deferred tax assets when it is more likely than not that some portion of the assets will not be realized. The Company did not have any valuation allowances for federal income taxes on its deferred tax asset of $16.5 million as of March 31, 2012 and $16.0 million as of December 31, 2011. Management believes it is more likely than not that the results of future operations will generate sufficient federal taxable income to realize the deferred federal tax assets. The Company had a state valuation allowance of $320,000 as of March 31, 2012, and as of December 31, 2011.

Liquidity and Capital Resources

Liquidity management

The objective of liquidity management is to ensure we have the ability to generate sufficient cash or cash equivalents in a timely and cost-effective manner to meet our commitments as they become due. Typical demands on liquidity are run-off from demand deposits, maturing time deposits which are not renewed, and fundings under credit commitments to customers. Funds are available from a number of sources, such as from the core deposit base and from loans and securities repayments and maturities.

Additionally, liquidity is provided from sales of the securities portfolio, fed fund lines with correspondent banks, the Federal Reserve and the FHLB, the ability to acquire large and brokered deposits, and the ability to sell loan participations to other banks. These alternatives are an important part of our liquidity plan and provide flexibility and efficient execution of the asset-liability management strategy.

Our Asset-Liability Management Committee oversees our liquidity position, the parameters of which are approved by the Bank's Board of Directors.Our liquidity position is monitored monthly by producing a liquidity report, which measures the amount of liquid versus non-liquid assets and liabilities. Ourliquidity management framework includes measurement of several key elements, such as the loan to deposit ratio, a liquidity ratio, and a dependency ratio. The Company's liquidity framework also incorporates contingency planning to assess the nature and volatility of funding sources and to determine alternatives to these sources. While core deposits and loan and investment repayments are principal sources of liquidity, funding diversification is another key element of liquidity management and is achieved by strategically varying depositor types, terms, funding markets, and instruments.

40

Parent Company liquidity

The parent company's liquidity is managed to provide the funds necessary to pay dividends to shareholders, service debt, invest in subsidiaries as necessary, and satisfy other operating requirements. The parent company's primary funding sources to meet its liquidity requirements are dividends and payments from the Bank and proceeds from the issuance of equity (i.e. stock option exercises, stock offerings). Another source of funding for the parent company includes the issuance of subordinated debentures. Management believes our current level of cash at the holding company of approximately $18.0 million will be sufficient to meet all projected cash needs for at least the next year.

As of March 31, 2012, the Company had $82.6 million of outstanding subordinated debentures as part of nine Trust Preferred Securities Pools. These securities are classified as debt but are included in regulatory capital and the related interest expense is tax-deductible, which makes them a very attractive source of funding.

Bank liquidity

During the first quarter of 2012, we maintained a strong liquidity position by targeting core funding while reducing certain volatile deposit sources. Noninterest-bearing demand deposits grew $6.7 million, interest-bearing checking and money market accounts increased $3.4 million.

The Bank has a variety of funding sources available to increase financial flexibility. In addition to amounts currently borrowed, at March 31, 2012, the Bank could borrow an additional $156.6 million from the FHLB of Des Moines under blanket loan pledges and has an additional $430.5 million available from the Federal Reserve Bank under a pledged loan agreement. The Bank has unsecured federal funds lines with three correspondent banks totaling $35.0 million.

Of the $506.8 million of the securities available for sale at March 31, 2012, $225.7 million was pledged as collateral for deposits of public institutions, treasury, loan notes, and other requirements. The remaining $281.2 million could be pledged or sold to enhance liquidity, if necessary.

The Bank belongs to the Certificate of Deposit Account Registry Service, or CDARS, which allows us to provide our customers with access to additional levels of FDIC insurance coverage on their deposits. The Company considers the reciprocal deposits placed through the CDARS program as core funding and does not report the balances as brokered sources in its internal or external financial reports. As of March 31, 2012, the Bank had $30.9 million of reciprocal CDARS money market sweep balances and $7.6 million of reciprocal certificates of deposits outstanding. In addition to the reciprocal deposits available through CDARS, the Company has access to the “one-way buy” program, which allows the Company to bid on the excess deposits of other CDARS member banks. The Company will report any outstanding “one-way buy” funds as brokered funds in its internal and external financial reports. At March 31, 2012, we had no outstanding “one-way buy” deposits.

In addition, the Bank has the ability to sell certificates of deposit through various national or regional brokerage firms, if needed. At March 31, 2012, brokered certificate of deposit balances were $101.6 million, and represented 3.8% of total deposits at March 31, 2012.

In the normal course of business, the Bank enters into certain forms of off-balance sheet transactions, including unfunded loan commitments and letters of credit. These transactions are managed through the Bank's various risk management processes. Management considers both on-balance sheet and off-balance sheet transactions in its evaluation of the Company's liquidity. The Bank has $650.2 million in unused commitments as of March 31, 2012. While this commitment level exceeds the Company's current liquidity resources, the nature of these commitments is such that the likelihood of funding them in the aggregate at any one time is low.

Capital Resources

The Company and the Bank are subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional

41

discretionary actions by regulators that, if undertaken, could have a direct material effect on the financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and its bank affiliate must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The banking affiliate’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets. To be categorized as “well capitalized”, banks must maintain minimum total risk-based (10%), Tier 1 risk-based (6%) and Tier 1 leverage ratios (5%). As of March 31, 2012, and December 31, 2011, the Company and the Bank met all capital adequacy requirements to which they are subject.

The Company continues to exceed regulatory standards and met the definition of “well-capitalized” (the highest category) at March 31, 2012, and December 31, 2011.

The following table summarizes the Company’s risk-based capital and leverage ratios at the dates indicated:

(Dollars in thousands)	March 31, 2012			December 31, 2011
Average common equity to average assets	6.48		%	5.84		%
Tier 1 capital to risk weighted assets	12.48		%	12.40		%
Total capital to risk weighted assets	13.85		%	13.78		%
Tier 1 common equity to risk weighted assets	7.46		%	7.32		%

While our regulatory capital ratios at the Bank are more than adequate, our capital plan targets a tangible common equity to tangible assets ratio of 7% or better by the end of 2014.  This capital plan contemplates 1) the redemption of all or part of the $35 million of preferred stock in the Company currently held by the U.S. Treasury through the Capital Purchase Program by the end of 2012 and 2) no significant acquisition activities.  The Company intends to seek regulatory approval with the Federal Reserve and the FDIC to redeem the preferred stock in conjunction with the completion of its annual safety & soundness exam in June, 2012.

Critical Accounting Policies

The impact and any associated risks related to the Company’s critical accounting policies on business operations are discussed throughout “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” where such policies affect our reported and expected financial results. For a detailed discussion on the application of these and other accounting policies, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

New Accounting Standards

FASB ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” On January 1, 2012, the Company adopted new authoritative guidance under this ASU which is the result of joint efforts by the FASB and IASB to develop a single, converged fair value framework on how (not when) to measure fair value and on what disclosures to provide about fair value measurements. The amended guidance changes several aspects of the fair value measurement guidance in FASB Accounting Standards Codification 820 “Fair Value Measurement” including the following provisions:

• Application of the concepts of highest and best use and valuation premise

• Introduction of a option to measure groups of offsetting assets and liabilities on a net basis

• Incorporation of certain premiums and discounts in fair value measurements

• Measurement of the fair value of certain instruments classified in shareholders' equity

In addition, the amended guidance includes several new fair value disclosure requirements, including information about valuation techniques and unobservable inputs used in Level 3 fair value measurements and a narrative description of Level 3 measurements' sensitivity to changes in unobservable inputs. The adoption of this guidance did not have a material impact on the the Company's consolidated financial statements.

FASB ASU 2011-05, “Presentation of Comprehensive Income" On January 1, 2012, the Company adopted new authoritative guidance which amends Topic 220, Comprehensive Income by eliminating the option to present components of other comprehensive income (OCI) in the statement of stockholders' equity. This new guidance requires entities to present all nonowner changes in stockholders' equity either as a single continuous statement of comprehensive income or as two separate but consecutive statements. This ASU also requires entities to present all reclassification adjustments from OCI to net income on the face of the statement of comprehensive income. The adoption of this guidance did not have a material impact on the the Company's consolidated financial statements.

FASB ASU 2011-08, "Testing Goodwill for Impairment" On January 1, 2012, the Company adopted new authoritative guidance which permits entities to first perform a qualitative assessment to determine whether it is more likely than not (a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount. If the entity determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, it would perform the first step of the goodwill impairment test; otherwise, no further impairment test would be required. The adoption of this guidance did not have a material impact on the the Company's consolidated financial statements.

FASB ASU 2011-11, "Disclosures about Offsetting Assets and Liabilities" In December 2011, the FASB issued ASU 2011-11 which requires entities with financial instruments and derivatives that are either offset on the balance sheet or subject to a master nettting or similar arrangement are required to disclose the following information separately for assets and liabilities in a tabular format:

• Gross amounts of recognized assets and liabilities

• Offsetting amounts that determine the net amount presented in the balance sheet

• Amounts subject to an enforceable master netting arrangement that were not already included in the disclosure required by (2) above, including

◦ Amounts related to recognized financial instruments and other derivative instruments if either (a) management makes an accounting election not to offset the amounts, or (b) the amounts do not meet

44

the right of setoff conditions in ASC 210-30-45, Balance Sheet: Offsetting, or in ASC 815-10-45, Derivatives and Hedging

◦ Amounts related to financial collateral

• Net amounts after deducting the amounts in (4) from the amounts in (3) above

In addition to the tabular disclosure described above, entities are required to provide a description of the setoff rights associated with assets and liabilities subject to an enforceable master netting arrangement. This ASU is effective for the years beginning on or after January 1, 2013, and interim periods within those annual periods. The guidance must be applied retrospectively for any period presented that begins before an entity's date of initial application. The Company believes this ASU will not have a material impact on the Company's consolidated financial statements.

FASB ASU 2011-12, "Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05" On January 1, 2012, the Company adopted new authoritative guidance which indefinitely defers the new provisions under ASU 2011-05 which required entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented for both interim and annual financial statements. The adoption of this guidance did not have a material impact on the the Company's consolidated financial statements.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The disclosures set forth in this item are qualified by the section captioned “Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995” included in Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations of this report and other cautionary statements set forth elsewhere in this report.

Market risk arises from exposure to changes in interest rates and other relevant market rate or price risk. The Company faces market risk in the form of interest rate risk through transactions other than trading activities. Market risk from these activities, in the form of interest rate risk, is measured and managed through a number of methods. The Company uses financial modeling techniques to measure interest rate risk. These techniques measure the sensitivity of future earnings due to changing interest rate environments. Guidelines established by the Bank’s Asset/Liability Management Committee and approved by the Bank’s Board of Directors are used to monitor exposure of earnings at risk. General interest rate movements are used to develop sensitivity as the Company feels it has no primary exposure to a specific point on the yield curve. These limits are based on the Company’s exposure to a 100 basis points and 200 basis points immediate and sustained parallel rate move, either upward or downward. In today’s low interest rate environment, the Company also monitors its exposure to immediate and sustained parallel rate increases of 300 basis points and 400 basis points.

Interest rate simulations for March 31, 2012, demonstrate that a rising rate environment will have a positive impact on net interest income.

ITEM 4: CONTROLS AND PROCEDURES

Under the supervision and with the participation of the Company’s Chief Executive Officer (CEO) and the Chief Financial Officer (CFO), management has evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Exchange Act Rule 13a-15, as of March 31, 2012. Disclosure controls and procedures include without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Based on that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures were not effective as of March 31, 2012, due to the fact that there was a material weakness in our internal control over financial reporting as discussed in more detail in our Annual Report on Form 10-K for fiscal year 2011 under Part II, Item 9A.

There were no changes during the period covered by this Quarterly Report on Form 10-Q in the Company’s internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, those controls.

46

Remediation Plan

Management has been actively engaged in developing remediation plans to address the above material weakness. The remediation efforts include, but are not limited to, the following:

• Implemented a commercially available system specifically designed to address the accounting requirements under ASC 310-30, "Loans & Debt Securities Acquired with Deteriorated Credit Quality";

• Implemented additional reconciliation and other procedures surrounding the calculation of the effective yield for acquired loans;

• Hired additional personnel in the Loss Share accounting department;

• Utilization of an accounting firm to consult in the analysis and preparation of accounting entries required under ASC 310-30; and

• Reversed contractual interest related to the acquired loans.

In addition, under the direction of the Audit Committee, management will continue to review and make necessary changes to the overall design of the company’s internal control environment, as well as to policies and procedures to improve the overall effectiveness of internal control over financial reporting.

Management believes the foregoing efforts when completed and verified will effectively remediate the material weakness. As the company continues to evaluate and work to improve its internal control over financial reporting, management may determine to take additional measures to address control deficiencies or determine to modify the remediation plan described above. If not remediated, these control deficiencies could result in further material misstatements to the Company’s financial statements.

PART II – OTHER INFORMATION

ITEM 1: LEGAL PROCEEDINGS

The following information supplements the discussion in Part I, Item 3 “Legal Proceedings” in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011, and as updated by the Company's Quarterly Report on Form 10-Q for the quarters ended March 31, 2012:

Distinctive Notes

The Bank, along with other co-defendants has been named as a defendant in two lawsuits filed by persons alleging to be clients of the Bank’s Trust division who invested in promissory notes (the "Distinctive Notes") issued by Distinctive Properties (UK) Limited (“Distinctive Properties”), a company involved in the purchase and development of real estate in the United Kingdom. The Company denies plaintiffs’ allegations and intends to vigorously defend the lawsuits.

Rosemann, et al. v. Martin Sigillito, et al. 

In one of the lawsuits, the plaintiffs allege that the investments in the Distinctive Notes were part of a multi-million dollar Ponzi scheme. Plaintiffs allege to hold such promissory notes in accounts with the Trust division and that, among other things, the Bank was negligent, breached its fiduciary duties and breached its contracts. Plaintiffs also allege that the Bank violated the Racketeer Influenced and Corrupt Organizations Act (“RICO”). Plaintiffs, in the aggregate, are seeking damages from defendants, including the Bank, in excess of $25.0 million as well as their costs and attorneys’ fees and trebled damages under RICO.

As previously reported, on July 1, 2011, the United States moved to intervene in the case for purposes of securing a stay of the case pending completion of it's criminal case against the individual defendants, and did not include the Company, the Bank or any affiliates thereof.

47

BJD, LLC and Barbara Dunning v. Enterprise Bank & Trust, et. al.

The Bank has also been named as a defendant in this case, relating to BJD’s investment in the Distinctive Notes.

Plaintiffs allege that the Bank, and the other defendants breached their fiduciary duties and were negligent in allowing plaintiffs to invest in the Distinctive Notes because the loan program was allegedly never funded and the assets of the borrower did not exist or were overvalued. Plaintiffs are seeking approximately $800,000 in damages, 9% interest, punitive damages, attorneys’ fees and costs.

On July 11, 2011, the U.S. Attorney's Office moved to intervene in this case as well for purposes of seeking a stay of certain discovery pending completion of the above described criminal proceedings. As a result, certain discovery in the case was put on hold for the duration of such criminal proceedings.

The criminal proceedings against Sigillito began on March 19, 2012. After a four week trial, Sigillito was found guilty of 20 counts of wire fraud, mail fraud, conspiracy and money laundering. Following this verdict, the judge lifted the stay and has scheduled a Rule 16 conference in the Rosemann case for May 31, 2012. The court in the Dunning case has granted the Bank's motion to compel arbitration and stay preceedings and scheduled a case management conference for May 10, 2012.

William Mark Scott v. Enterprise Financial Services Corp

On April 10, 2012, a putative class action was filed in the United States District Court for the Eastern District of

Missouri captioned William Mark Scott v. Enterprise Financial Services Corp, Peter F. Benoist, and Frank H. Sanfilippo. The complaint asserts claims for violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on behalf of a putative class of purchasers of the Company's stock between April 20, 2010 and January 25, 2012, inclusive. The complaint alleges, among other things, that defendants made false and misleading statements and "failed to disclose that the Company was improperly recording income on loans covered under loss share agreements with the FDIC" and that, as a result, "the Company's financial statements were materially false and misleading at all relevant times." The action seeks unspecified damages and costs and expenses. The Company denies plaintiffs’ allegations and intends to vigorously defend the lawsuit.

ITEM 1A: RISK FACTORS

Please see the cautionary language regarding forward-looking statements in the introduction to Item 2 of Part I of this Report on Form 10-Q, and Part I - Item 1A of our Report on Form 10-K for the fiscal year ended December 31, 2011, for information regarding risk factors.

Summary of Significant Accounting Policies

3 Months Ended

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]

Significant Accounting Policies [Text Block]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies used by Enterprise Financial Services Corp (the “Company” or “Enterprise”) in the preparation of the condensed consolidated financial statements are summarized below:

Business and Consolidation

Enterprise is a financial holding company that provides a full range of banking and wealth management services to individuals and corporate customers located in the St. Louis, Kansas City and Phoenix metropolitan markets through its banking subsidiary, Enterprise Bank & Trust (the “Bank”).

Operating results for the three months ended March 31, 2012 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2012. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

Basis of Financial Statement Presentation

The condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all information and footnotes required by U.S. GAAP for annual financial statements. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain 2011 amounts in the consolidated financial statements have been reclassified to conform to the 2012 presentation. These reclassifications have no effect on Net income or Shareholders' equity as previously reported.

FAIR VALUE MEASUREMENTS

Below is a description of certain assets and liabilities measured at fair value.

The following table summarizes financial instruments measured at fair value on a recurring basis as of March 31, 2012, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value.

• Securities available for sale. Securities classified as available for sale are reported at fair value utilizing Level 2 and Level 3 inputs. The Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions. At March 31, 2012, Level 3 securities available for sale include three Auction Rate Securities and a municipal bond issued by a school district.

• Portfolio Loans. Certain fixed rate portfolio loans are accounted for as trading instruments and reported at fair value. Fair value on these loans is determined using a third party valuation model with observable Level 2 market data inputs.

• State tax credits held for sale. At March 31, 2012, of the $48.2 million of state tax credits held for sale on the condensed consolidated balance sheet, approximately $24.7 million were carried at fair value. The remaining $23.5 million of state tax credits were accounted for at cost.

The fair value of the state tax credits carried at fair value decreased $283,000 for the quarter ended March 31, 2012 compared to $164,000 for the same period in 2011. These fair value changes are included in Gain on State tax credits, net in the condensed consolidated statements of operations.

The Company is not aware of an active market that exists for the 10-year streams of state tax credit financial instruments. However, the Company’s principal market for these tax credits consists of Missouri state residents who buy these credits and from local and regional accounting firms who broker them. As such, the Company employed a discounted cash flow analysis (income approach) to determine the fair value.

The fair value measurement is calculated using an internal valuation model with observable market data including discounted cash flows based upon the terms and conditions of the tax credits. Assuming that the underlying project remains in compliance with the various federal and state rules governing the tax credit program, each project will generate about 10 years of tax credits. The inputs to the fair value calculation include: the amount of tax credits generated each year, the anticipated sale price of the tax credit, the timing of the sale and a discount rate. The discount rate is defined as the LIBOR swap curve at a point equal to the remaining life in years of credits plus a 205 basis point spread. With the exception of the discount rate, the other inputs to the fair value calculation are observable and readily available. The discount rate is considered a Level 3 input because it is an “unobservable input” and is based on the Company’s assumptions. An increase in the discount rate utilized would generally result in a lower estimated fair value of the tax credits. Alternatively, a decrease in the discount rate utilized would generally result in a higher estimated fair value of the tax credits. Given the significance of this input to the fair value calculation, the state tax credit assets are reported as Level 3 assets.

• Derivatives. Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains counterparty quotations to value its interest rate swaps and caps. In addition, the Company validates the counterparty quotations with third party valuation sources. Derivatives with negative fair values are included in Other liabilities in the consolidated balance sheets. Derivatives with positive fair value are included in Other assets in the consolidated balance sheets.

Level 3 financial instruments

The following table presents the changes in Level 3 financial instruments measured at fair value on a recurring basis as of March 31, 2012.

• Purchases, sales, issuances and settlements, net. There were no Level 3 purchases during the quarter ended March 31, 2012.

• Transfers in and/or out of Level 3. The transfer out of Level 3 is related to a newly issued mortgage-backed security purchased in the fourth quarter of 2011 which was originally priced using Level 3 assumptions. In the first quarter of 2012, a third party pricing service became available.

From time to time, the Company measures certain assets at fair value on a nonrecurring basis. These include assets that are measured at the lower of cost or fair value that were recognized at fair value below cost at the end of the period. The following table presents financial instruments and non-financial assets measured at fair value on a non-recurring basis as of March 31, 2012.

(1) The amounts represent only balances measured at fair value during the period and still held as of the reporting date.

Impaired loans are reported at the fair value of the underlying collateral. Fair values for impaired loans are obtained from current appraisals by qualified licensed appraisers or independent valuation specialists. Other real estate owned is adjusted to fair value upon foreclosure of the underlying loan. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value less costs to sell. Fair value of other real estate is based upon the current appraised values of the properties as determined by qualified licensed appraisers and the Company’s judgment of other relevant market conditions. Certain state tax credits are reported at cost.

Following is a summary of the carrying amounts and fair values of the Company’s financial instruments on the consolidated balance sheets at March 31, 2012, and December 31, 2011.

At March 31, 2012, and December 31, 2011, there were no holdings of securities of any one issuer in an amount greater than 10% of shareholders’ equity, other than the U.S. government agencies and sponsored enterprises. The residential mortgage-backed securities are all issued by U.S. government sponsored enterprises. Available for sale securities having a carrying value of $225.7 million and $287.8 million at March 31, 2012, and December 31, 2011, respectively, were pledged as collateral to secure deposits of public institutions and for other purposes as required by law or contract provisions.

The amortized cost and estimated fair value of debt securities classified as available for sale at March 31, 2012, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. The weighted average life of the mortgage-backed securities is approximately 4 years.

The unrealized losses at both March 31, 2012, and December 31, 2011, were attributable to changes in market interest rates since the securities were purchased. Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security and (5) the intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value. At March 31, 2012, management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired.

The gross gains and gross losses realized from sales of available-for-sale investment securities were as follows:

Segment Reporting [Abstract]

Segment Reporting Disclosure [Text Block]

SEGMENT REPORTING

The Company has two primary operating segments, Banking and Wealth Management, which are delineated by the products and services that each segment offers. The segments are evaluated separately on their individual performance, as well as their contribution to the Company as a whole.

The Banking operating segment consists of a full-service commercial bank, with locations in St. Louis, Kansas City, and Phoenix. The majority of the Company’s assets and income result from the Banking segment. All banking locations have the same product and service offerings, have similar types and classes of customers and utilize similar service delivery methods. Pricing guidelines and operating policies for products and services are the same across all regions.

The Wealth Management segment includes the Trust division of the Bank and the state tax credit brokerage activities. The Trust division provides estate planning, investment management, and retirement planning as well as consulting on management compensation, strategic planning and management succession issues. State tax credits are part of a fee initiative designed to augment the Company’s wealth management segment and banking lines of business.

The Corporate segment’s principal activities include the direct ownership of the Company’s banking subsidiary and the issuance of debt and equity. Its principal source of liquidity is dividends from its subsidiaries and stock option exercises.

The financial information for each business segment reflects that information which is specifically identifiable or which is allocated based on an internal allocation method. There were no material intersegment revenues among the three segments. Management periodically makes changes to methods of assigning costs and income to its business segments to better reflect operating results. When appropriate, these changes are reflected in prior year information presented below.

Following are the financial results for the Company’s operating segments.

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES [Abstract]

Commitments and Contingencies Disclosure [Text Block]

COMMITMENTS AND CONTINGENCIES

The Company issues financial instruments with off balance sheet risk in the normal course of the business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets.

The Company’s extent of involvement and maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments.

The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. At March 31, 2012, there were $1.1 million of unadvanced commitments on impaired loans. Other liabilities include approximately $212,000 for estimated losses attributable to the unadvanced commitments on impaired loans.

The contractual amounts of off-balance-sheet financial instruments as of March 31, 2012, and December 31, 2011, are as follows:

(in thousands)	March 31, 2012		December 31, 2011
Commitments to extend credit	$	603,935	$	547,657
Standby letters of credit	46,259		43,973

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments usually have fixed expiration dates or other termination clauses and may require payment of a fee. Of the total commitments to extend credit at March 31, 2012, and December 31, 2011, approximately $61.8 million and $75.7 million, respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These standby letters of credit are issued to support contractual obligations of the Company’s customers. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. The approximate remaining term of standby letters of credit range from 6 months to 5 years at March 31, 2012.

Contingencies

The Company and its subsidiaries are, from time to time, parties to various legal proceedings arising out of their businesses. Other than those described below, management believes that there are no such proceedings pending or threatened against the Company or its subsidiaries which, if determined adversely, would have a material adverse effect on the business, consolidated financial condition, results of operations or cash flows of the Company or any of its subsidiaries.

Distinctive Notes

The Bank, along with other co-defendants has been named as a defendant in two lawsuits filed by persons alleging to be clients of the Bank’s Trust division who invested in promissory notes (the "Distinctive Notes") issued by Distinctive Properties (UK) Limited (“Distinctive Properties”), a company involved in the purchase and development of real estate in the United Kingdom. The Company is unable to estimate a reasonably possible loss for the cases described below because the proceedings are in early stages and there are significant factual issues to be determined and resolved in each case. The Company denies plaintiffs’ allegations and intends to vigorously defend the lawsuits.

Rosemann, et al. v. Martin Sigillito, et al. 

In one of the lawsuits, the plaintiffs allege that the investments in the Distinctive Notes were part of a multi-million dollar Ponzi scheme. Plaintiffs allege to hold such promissory notes in accounts with the Trust division and that, among other things, the Bank was negligent, breached its fiduciary duties and breached its contracts. Plaintiffs also allege that the Bank violated the Racketeer Influenced and Corrupt Organizations Act (“RICO”). Plaintiffs, in the aggregate, are seeking damages from defendants, including the Bank, in excess of $25.0 million as well as their costs and attorneys’ fees and trebled damages under RICO.

As previously reported, on July 1, 2011, the United States moved to intervene in the case for purposes of securing a stay of the case pending completion of it's criminal case against the individual defendants, and did not include the Company, the Bank or any affiliates thereof.

BJD, LLC and Barbara Dunning v. Enterprise Bank & Trust, et. al.

The Bank has also been named as a defendant in this case, relating to BJD’s investment in the Distinctive Notes. Plaintiffs allege that the Bank, and the other defendants breached their fiduciary duties and were negligent in allowing plaintiffs to invest in the Distinctive Notes because the loan program was allegedly never funded and the assets of the borrower did not exist or were overvalued. Plaintiffs are seeking approximately $800,000 in damages, 9% interest, punitive damages, attorneys’ fees and costs.

On July 11, 2011, the U.S. Attorney's Office moved to intervene in this case as well for purposes of seeking a stay of certain discovery pending completion of the above described criminal proceedings. As a result, certain discovery in the case was put on hold for the duration of such criminal proceedings.

The criminal proceedings against Sigillito began on March 19, 2012. After a four week trial, Sigillito was found guilty of 20 counts of wire fraud, mail fraud, conspiracy and money laundering. Following this verdict, the judge lifted the stay and has scheduled a Rule 16 conference in the Rosemann case for May 31, 2012. The court in the Dunning case has granted the Bank's motion to compel arbitration and stay proceedings and scheduled a case management conference for May 10, 2012.

William Mark Scott v. Enterprise Financial Services Corp, et. al.

On April 10, 2012, a putative class action was filed in the United States District Court for the Eastern District of Missouri captioned William Mark Scott v. Enterprise Financial Services Corp, Peter F. Benoist, and Frank H. Sanfilippo. The complaint asserts claims for violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on behalf of a putative class of purchasers of the Company's stock between April 20, 2010 and January 25, 2012, inclusive. The complaint alleges, among other things, that defendants made false and misleading statements and "failed to disclose that the Company was improperly recording income on loans covered under loss share agreements with the FDIC" and that, as a result, "the Company's financial statements were materially false and misleading at all relevant times." The action seeks unspecified damages and costs and expenses. The Company is unable to estimate a reasonably possible loss for the case because the proceeding is in an early stage and there are significant factual issues to be determined and resolved. The Company denies plaintiffs’ allegations and intends to vigorously defend the lawsuit.

The Company grants commercial, residential, and consumer loans primarily in the St. Louis, Kansas City and Phoenix metropolitan areas. The Company has a diversified loan portfolio, with no particular concentration of credit in any one economic sector; however, a substantial portion of the portfolio is concentrated in and secured by real estate. The ability of the Company’s borrowers to honor their contractual obligations is partially dependent upon the local economy and its effect on the real estate market.

A summary of the year-to-date activity in the allowance for loan losses and the recorded investment in Non-covered loans by portfolio class and category based on impairment method through March 31, 2012, and at December 31, 2011, is as follows:

The restructured Non-covered loans primarily resulted from interest rate concessions and changing the terms of the loans. As of March 31, 2012, the Company has allocated $2.5 million of specific reserves to the loans that have been restructured. At March 31, 2012, the Company has a commitment to lend an additional $1.1 million to a customer with an outstanding loan that has been classified as restructured and has allocated a $212,000 reserve to these loans.

The recorded investment by category for the Non-covered loans that have been restructured and subsequently defaulted for the three months ended March 31, 2012, is as follows:

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, and current economic factors among other factors. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings:

• Grades 1, 2, and 3 - These grades include loans to borrowers with a continuous record of strong earnings, sound balance sheet condition and capitalization, ample liquidity with solid cash flow and whose management team has experience and depth within their industry.

• Grade 4 – This grade includes loans to borrowers with positive trends in profitability, satisfactory capitalization and balance sheet condition, and sufficient liquidity and cash flow.

• Grade 5 – This grade includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization, liquidity, and cash flow.

• Grade 6 – This grade includes loans to borrowers where an adverse change or perceived weakness has occurred, but may be correctable in the near future. Alternatively, this rating category may also include circumstances where the company is starting to reverse a negative trend or condition, or have recently been upgraded from a 7, 8, or 9 rating.

• Grade 7 – Watch credits are companies that have experienced financial setback of a nature that are not determined to be severe or influence ‘ongoing concern’ expectations. Borrowers within this category are expected to turnaround within a 12-month period of time. Although possible, no loss is anticipated, due to strong collateral and/or guarantor support.

• Grade 8 – Substandard credits will include those companies that are characterized by significant losses and sustained downward trends in balance sheet condition, liquidity, and cash flow. Repayment reliance may have shifted to secondary sources. Collateral exposure may exist and additional reserves may be warranted.

• Grade 9 – Doubtful credits include borrowers that may show deteriorating trends that are unlikely to be corrected. Collateral values may appear insufficient for full recovery, therefore requiring a partial charge-off, or debt renegotiation with the borrower. Borrower may have declared bankruptcy or bankruptcy is likely in the near term. All doubtful rated credits will be on non-accrual.

Portfolio Loans Covered by Loss Share

PORTFOLIO LOANS COVERED by Loss Share [Abstract]

Portfolio loans covered by FDIC loss share [Text Block]

PORTFOLIO LOANS COVERED BY LOSS SHARE ("Covered loans")

Purchased loans acquired in a business combination, including loans purchased in our FDIC-assisted transactions, are recorded at estimated fair value on their purchase date without a carryover of the related allowance for loan losses. Purchased credit-impaired loans are loans that have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments. Evidence of credit quality deterioration as of the purchase date may include factors such as past due and non-accrual status. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable yield. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges or a reclassification of the difference from non-accretable to accretable with a positive impact on interest income, prospectively. Further, any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan when there is a reasonable expectation about the amount and timing of such cash flows. Acquired loans that have common risk characteristics are aggregated into pools. The Company remeasures contractual and expected cash flows, at the pool-level, on a quarterly basis.

Inputs to the determination of expected cash flows include contractual cash flows, cumulative default and prepayment data as well as loss severity and recovery lag information. Cumulative default and prepayment data are calculated via a transition matrix. The transition matrix is a matrix of probability values that specifies the probability of a loan pool transitioning into a loss given its delinquency state (e.g. 0-30 days past due, 31 to 60 days, etc.) at the remeasurement date. Loss severity factors are based upon industry data along with actual charge-off data within the loan pools and recovery lags are based upon industry data along with experience with the collateral within the loan pools.

Covered loans are also subject to the Company’s internal and external credit review and are risk rated using the same criteria as loans originated by the Company. However, risk ratings are not always a clear indicator of the Company's losses on acquired loans as a majority of the losses are recoverable from the FDIC under the loss-sharing agreements.

Derivative Financial Instruments

DERIVATIVE FINANCIAL INSTRUMENTS [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

DERIVATIVE FINANCIAL INSTRUMENTS

The Company is a party to various derivative financial instruments that are used in the normal course of business to meet the needs of its clients and as part of its risk management activities. These instruments include interest rate swaps and option contracts. The Company does not enter into derivative financial instruments for trading or speculative purposes.

Interest rate swap contracts involve the exchange of fixed and floating rate interest payment obligations without the exchange of the underlying principal amounts. The Company enters into interest rate swap contracts on behalf of its

clients and also utilizes such contracts to reduce or eliminate the exposure to changes in the cash flows or fair value of hedged assets or liabilities due to changes in interest rates. Interest rate option contracts consist of caps and provide for the transfer or reduction of interest rate risk in exchange for a fee.

All derivative financial instruments, whether designated as hedges or not, are recorded on the consolidated balance sheet at fair value within Other assets or Other liabilities. The accounting for changes in the fair value of a derivative in the consolidated statement of operations depends on whether the contract has been designated as a hedge and qualifies for hedge accounting. At March 31, 2012, and December 31, 2011, the Company did not have any derivatives designated as cash flow or fair value hedges.

Using derivative instruments means assuming counterparty credit risk. Counterparty credit risk relates to the loss the Company could incur if a counterparty were to default on a derivative contract. Notional amounts of derivative financial instruments do not represent credit risk, and are not recorded in the consolidated balance sheet. They are used merely to express the volume of this activity. The overall credit risk and exposure to individual counterparties is monitored. The Company does not anticipate nonperformance by any counterparties. The amount of counterparty credit exposure is the unrealized gains, if any, on such derivative contracts. At March 31, 2012, the Company had $1.4 million of unrealized gains. At March 31, 2012, the Company had pledged cash of $2.9 million and at December 31, 2011, the Company had pledged cash of $2.7 million, as collateral in connection with our interest rate swap agreements.

Risk Management Instruments. The Company enters into certain derivative contracts to economically hedge state tax credits and certain loans.

• Economic hedge of state tax credits. In November 2008, the Company paid $2.1 million to enter into a series of interest rate caps in order to economically hedge changes in fair value of the State tax credits held for sale. In February 2010, the Company paid $751,000 for an additional series of interest rate caps. See Note 10—Fair Value Measurements for further discussion of the fair value of the state tax credits.

• Economic hedge of prime based loans. Previously, the Company had two outstanding interest rate swap agreements whereby the Company paid a variable rate of interest equivalent to the prime rate and received a fixed rate of interest. The swaps were designed to hedge the cash flows associated with a portion of prime based loans and had been designated as cash flow hedges. However, in December 2008, due to a variable rate differential, the Company concluded the cash flow hedges would not be prospectively effective and the hedges were dedesignated. The swaps were terminated in February 2009. The unrealized gain prior to dedesignation was included in Accumulated other comprehensive income and is being amortized over the expected life of the related loans. For the three months ended March 31, 2011, $44,000 was reclassified into Miscellaneous income. At December 31, 2011, there were no additional amounts remaining in Accumulated other comprehensive income to be reclassified into operations.

The table below summarizes the notional amounts and fair values of the derivative instruments used to manage risk.

Earnings Per Share [Text Block]

EARNINGS PER SHARE

Basic earnings per common share data is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method for convertible securities related to the issuance of trust preferred securities.
