NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation – The accompanying unaudited condensed consolidated interim financial statements ("consolidated financial statements") of First Midwest Bancorp, Inc. (the "Company"), a Delaware corporation, were prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") for quarterly reports on Form 10-Q and reflect all adjustments that management deems necessary for the fair presentation of the financial position and results of operations for the periods presented. The results of operations for the quarter ended March 31, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016.

The accounting and reporting policies of the Company and its subsidiaries conform to U.S. generally accepted accounting principles ("GAAP") and general practices within the banking industry. The accompanying consolidated financial statements do not include certain information and note disclosures required by GAAP for complete annual financial statements. Therefore, these financial statements should be read in conjunction with the Company's 2015 Annual Report on Form 10-K ("2015 10-K"). The Company uses the accrual basis of accounting for financial reporting purposes. Certain reclassifications were made to prior year amounts to conform to the current year presentation.

Use of Estimates – The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Although these estimates and assumptions are based on the best available information, actual results could differ from those estimates.

Principles of Consolidation – The accompanying consolidated financial statements include the financial position and results of operations of the Company and its subsidiaries after elimination of all significant intercompany accounts and transactions. Assets held in a fiduciary or agency capacity are not assets of the Company or its subsidiaries and are not included in the consolidated financial statements.

The accounting policies related to business combinations, loans, the allowance for credit losses, and derivative financial instruments are presented below. For a summary of all other significant accounting policies, see Note 1, "Summary of Significant Accounting Policies," in the Company's 2015 10-K.

Business Combinations – Business combinations are accounted for under the acquisition method of accounting. Assets acquired and liabilities assumed are recorded at their estimated fair values as of the date of acquisition, with any excess of the purchase price of the acquisition over the fair value of the identifiable net tangible and intangible assets acquired recorded as goodwill. Alternatively, a gain is recorded if the fair value of assets purchased exceeds the fair value of liabilities assumed and consideration paid. The results of operations of the acquired business are included in the Condensed Consolidated Statements of Income from the effective date of the acquisition.

Loans – Loans held-for-investment are loans that the Company intends to hold until they are paid in full and are carried at the principal amount outstanding, including certain net deferred loan origination fees. Loan origination fees, commitment fees, and certain direct loan origination costs are deferred, and the net amount is amortized as a yield adjustment over the contractual life of the related loans or commitments and included in interest income. Fees related to standby letters of credit are amortized into fee income over the contractual life of the commitment. Other credit-related fees are recognized as fee income when earned. The Company's net investment in direct financing leases is included in loans and consists of future minimum lease payments and estimated residual values, net of unearned income. Interest income on loans is accrued based on principal amounts outstanding. Loans held-for-sale are carried at the lower of aggregate cost or fair value and included in other assets in the Consolidated Statements of Financial Condition.

Acquired and Covered Loans – Covered loans consists of loans acquired by the Company in Federal Deposit Insurance Corporation ("FDIC")-assisted transactions, which are covered by loss share agreements with the FDIC (the "FDIC Agreements"), under which the FDIC reimburses the Company for the majority of the losses and eligible expenses related to these assets during the coverage period. Acquired loans consist of all other loans that were acquired in business combinations that are not covered by FDIC Agreements. Covered loans and acquired loans are included within loans held-for-investment.

Acquired and covered loans are separated into (i) non-purchased credit impaired ("Non-PCI") and (ii) purchased credit impaired ("PCI") loans. Non-PCI loans include loans that did not have evidence of credit deterioration since origination at the acquisition date. PCI loans include loans that had evidence of credit deterioration since origination and for which it was probable at acquisition that the Company would not collect all contractually required principal and interest payments. Evidence of credit deterioration

8

was evaluated using various indicators, such as past due and non-accrual status. Leases and revolving loans do not qualify to be accounted for as PCI loans and are accounted for as Non-PCI loans.

The acquisition adjustment related to Non-PCI loans is amortized into interest income over the contractual life of the related loans. If an acquired non-PCI loan is renewed subsequent to the acquisition date, any remaining acquisition adjustment is accreted into interest income and the loan is considered a new loan that is no longer classified as an acquired loan.

PCI loans are accounted for based on estimates of expected future cash flows. To estimate the fair value, the Company generally aggregates purchased consumer loans and certain smaller balance commercial loans into pools of loans with common risk characteristics, such as delinquency status, credit score, and internal risk ratings. The fair values of larger balance commercial loans are estimated on an individual basis. Expected future cash flows in excess of the fair value of loans at the purchase date ("accretable yield") are recorded as interest income over the life of the loans if the timing and amount of the expected future cash flows can be reasonably estimated. The non-accretable yield represents the difference between contractually required payments and the expected future cash flows determined at acquisition. Subsequent increases in expected future cash flows are offset against the allowance for credit losses to the extent an allowance has been established or otherwise recognized as interest income prospectively. The present value of any decreases in expected future cash flows is recognized by recording a charge-off through the allowance for loan losses or providing an allowance for loan losses.

90-Days Past Due Loans –The Company's accrual of interest on loans is discontinued at the time the loan is 90 days past due unless the credit is sufficiently collateralized and in the process of renewal or collection.

Non-accrual Loans– Generally, corporate loans are placed on non-accrual status (i) when either principal or interest payments become 90 days or more past due unless the credit is sufficiently collateralized and in the process of renewal or collection, or (ii) when an individual analysis of a borrower's creditworthiness warrants a downgrade to non-accrual regardless of past due status. When a loan is placed on non-accrual status, unpaid interest credited to income in the current year is reversed, and unpaid interest accrued in prior years is charged against the allowance for loan losses. After the loan is placed on non-accrual, all debt service payments are applied to the principal on the loan. Future interest income may only be recorded on a cash basis after recovery of principal is reasonably assured. Non-accrual loans are returned to accrual status when the financial position of the borrower and other relevant factors indicate that the Company will collect all principal and interest.

Commercial loans and loans secured by real estate are charged-off when deemed uncollectible. A loss is recorded if the net realizable value of the underlying collateral is less than the outstanding principal and interest. Consumer loans that are not secured by real estate are subject to mandatory charge-off at a specified delinquency date and are usually not classified as non-accrual prior to being charged-off. Closed-end consumer loans, which include installment, automobile, and single payment loans, are usually charged-off no later than the end of the month in which the loan becomes 120 days past due.

PCI loans are generally considered accruing loans unless reasonable estimates of the timing and amount of expected future cash flows cannot be determined. Loans without reasonable future cash flow estimates are classified as non-accrual loans, and interest income is not recognized on those loans until the timing and amount of the expected future cash flows can be reasonably determined.

Troubled Debt Restructurings ("TDRs") – A restructuring is considered a TDR when (i) the borrower is experiencing financial difficulties, and (ii) the creditor grants a concession, such as forgiveness of principal, reduction of the interest rate, changes in payments, or extension of the maturity date. Loans are not classified as TDRs when the modification is short-term or results in an insignificant delay in payments. The Company's TDRs are determined on a case-by-case basis.

The Company does not accrue interest on a TDR unless it believes collection of all principal and interest under the modified terms is reasonably assured. For a TDR to begin accruing interest, the borrower must demonstrate some level of past performance and the future capacity to perform under the modified terms. Generally, six months of consecutive payment performance under the restructured terms is required before a TDR is returned to accrual status. However, the period could vary depending on the individual facts and circumstances of the loan. An evaluation of the borrower's current creditworthiness is used to assess the borrower's capacity to repay the loan under the modified terms. This evaluation includes an estimate of expected future cash flows, evidence of strong financial position, and estimates of the value of collateral, if applicable. For TDRs to be removed from TDR status in the calendar year after the restructuring, the loans must (i) have an interest rate and terms that reflect market conditions at the time of restructuring, and (ii) be in compliance with the modified terms. If the loan was restructured at below market rates and terms, it continues to be separately reported as restructured until it is paid in full or charged-off.

Impaired Loans – Impaired loans consist of corporate non-accrual loans and TDRs. A loan is considered impaired when it is probable that the Company will not collect all contractual principal and interest. With the exception of accruing TDRs, impaired loans are classified as non-accrual and are exclusive of smaller homogeneous loans, such as home equity, 1-4 family mortgages, and installment loans. Impaired loans with balances under a specified threshold are not individually evaluated for impairment. For all other impaired loans, impairment is measured by comparing the estimated value of the loan to the recorded book value.

9

The value of collateral-dependent loans is based on the fair value of the underlying collateral, less costs to sell. The value of other loans is measured using the present value of expected future cash flows discounted at the loan's initial effective interest rate.

Allowance for Credit Losses – The allowance for credit losses is comprised of the allowance for loan losses and the reserve for unfunded commitments, and is maintained by management at a level believed adequate to absorb estimated losses inherent in the existing loan portfolio. Determination of the allowance for credit losses is subjective since it requires significant estimates and management judgment, including the amounts and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans, consideration of current economic trends, and other factors.

Loans deemed to be uncollectible are charged-off against the allowance for loan losses, while recoveries of amounts previously charged-off are credited to the allowance for loan losses. Additions to the allowance for loan losses are charged to expense through the provision for loan losses. The amount of provision depends on a number of factors, including net charge-off levels, loan growth, changes in the composition of the loan portfolio, and the Company's assessment of the allowance for loan losses based on the methodology discussed below.

Allowance for Loan Losses– The allowance for loan losses consists of (i) specific reserves for individual loans where the recorded investment exceeds the value, (ii) an allowance based on a loss migration analysis that uses historical credit loss experience for each loan category, and (iii) an allowance based on other internal and external qualitative factors.

The specific reserves component of the allowance for loan losses is based on a periodic analysis of impaired loans exceeding a fixed dollar amount. If the value of an impaired loan is less than the recorded book value, the Company either establishes a valuation allowance (i.e., a specific reserve) equal to the excess of the book value over the value of the loan as a component of the allowance for loan losses or charges off the amount if it is a confirmed loss.

The general reserve component is based on a loss migration analysis, which examines actual loss experience by loan category for a rolling 8-quarter period and the related internal risk rating for corporate loans. The loss migration analysis is updated quarterly primarily using actual loss experience. This component is then adjusted based on management's consideration of many internal and external qualitative factors, including:

• Changes in the composition of the loan portfolio, trends in the volume of loans, and trends in delinquent and non-accrual loans that could indicate that historical trends do not reflect current conditions.

• Changes in credit policies and procedures, such as underwriting standards and collection, charge-off, and recovery practices.

• Changes in the experience, ability, and depth of credit management and other relevant staff.

• Changes in the quality of the Company's loan review system and Board of Directors oversight.

• The effect of any concentration of credit and changes in the level of concentrations, such as loan type or risk rating.

• Changes in the value of the underlying collateral for collateral-dependent loans.

• Changes in the national and local economy that affect the collectability of various segments of the portfolio.

• The effect of other external factors, such as competition and legal and regulatory requirements, on the Company's loan portfolio.

The allowance for loan losses also consists of an allowance on acquired and covered Non-PCI and PCI loans. No allowance for loan losses is recorded on acquired loans at the acquisition date. Subsequent to the acquisition date, an allowance for credit losses is established as necessary to reflect credit deterioration. The acquired Non-PCI allowance is based on management's evaluation of the acquired Non-PCI loan portfolio giving consideration to the current portfolio balance including the remaining acquisition adjustments, maturity dates, and overall credit quality. The allowance for covered Non-PCI loans is calculated in the same manner as the general reserve component based on a loss migration analysis as discussed above. The acquired and covered PCI allowance reflects the difference between the carrying value and the discounted expected future cash flows of the acquired and covered PCI loans. On a periodic basis, the adequacy of this allowance is determined through a re-estimation of expected future cash flows on all the outstanding acquired and covered PCI loans using either a probability of default/loss given default ("PD/LGD") methodology or a specific review methodology. The PD/LGD model is a loss model that estimates expected future cash flows using a probability of default curve and loss given default estimates. Acquired Non-PCI loans that have renewed subsequent to the respective acquisition dates are no longer classified as acquired loans. Instead, they are included with our general loan population and allocated an allowance based on a loss migration analysis.

Reserve for Unfunded Commitments– The Company also maintains a reserve for unfunded commitments, including letters of credit, for the risk of loss inherent in these arrangements. The reserve for unfunded commitments is estimated using the loss migration analysis from the allowance for loan losses, adjusted for probabilities of future funding requirements. The reserve for unfunded commitments is included in other liabilities in the Consolidated Statements of Financial Condition.

The establishment of the allowance for credit losses involves a high degree of judgment given the difficulty of assessing the factors impacting loan repayment and estimating the timing and amount of losses. While management utilizes its best judgment and

information available, the adequacy of the allowance for credit losses depends on a variety of factors beyond the Company's control, including the performance of its loan portfolio, the economy, changes in interest rates and property values, and the interpretation of loan risk classifications by regulatory authorities.

Derivative Financial Instruments – To provide derivative products to customers and in the ordinary course of business, the Company enters into derivative transactions as part of its overall interest rate risk management strategy to minimize significant unplanned fluctuations in earnings and expected future cash flows caused by interest rate volatility. All derivative instruments are recorded at fair value as either other assets or other liabilities in the Consolidated Statements of Financial Condition. Subsequent changes in a derivative's fair value are recognized in earnings unless specific hedge accounting criteria are met.

On the date the Company enters into a derivative contract, the derivative is designated as a fair value hedge, a cash flow hedge, or a non-hedge derivative instrument. Fair value hedges are designed to mitigate exposure to changes in the fair value of an asset or liability attributable to a particular risk, such as interest rate risk. Cash flow hedges are designed to mitigate exposure to variability in expected future cash flows to be received or paid related to an asset, liability, or other type of forecasted transaction. The Company formally documents all relationships between hedging instruments and hedged items, including its risk management objective and strategy at inception.

At the hedge's inception and quarterly thereafter, a formal assessment is performed to determine the effectiveness of the derivative in offsetting changes in the fair values or expected future cash flows of the hedged items in the current period and prospectively. If a derivative instrument designated as a hedge is terminated or ceases to be highly effective, hedge accounting is discontinued prospectively, and the gain or loss is amortized into earnings. For fair value hedges, the gain or loss is amortized over the remaining life of the hedged asset or liability. For cash flow hedges, the gain or loss is amortized over the same period that the forecasted hedged transactions impact earnings. If the hedged item is disposed of, any fair value adjustments are included in the gain or loss from the disposition of the hedged item. If the forecasted transaction is no longer probable, the gain or loss is included in earnings immediately.

For fair value hedges, changes in the fair value of the derivative instruments, as well as changes in the fair value of the hedged item, are recognized in earnings. For cash flow hedges, the effective portion of the change in fair value of the derivative instrument is reported as a component of accumulated other comprehensive loss and is reclassified to earnings when the hedged transaction is reflected in earnings.

Ineffectiveness is calculated based on the change in fair value of the hedged item compared with the change in fair value of the hedging instrument. For all types of hedges, any ineffectiveness in the hedging relationship is recognized in earnings during the period the ineffectiveness occurs.

2. RECENT ACCOUNTING PRONOUNCEMENTS

Adopted Accounting Pronouncements

Amendments to Consolidation Analysis: In February 2015, the Financial Accounting Standards Board ("FASB") issued guidance that updates current accounting for the consolidation of certain legal entities. This guidance modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs") or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, affects the consolidation analysis of reporting entities that are involved with VIEs, and provides certain exceptions from consolidation guidance for certain reporting entities. This guidance is effective for annual and interim periods beginning after December 15, 2015. The adoption of this guidance on January 1, 2016 did not materially impact the Company's financial condition, results of operations, or liquidity.

Simplifying the Presentation of Debt Issuance Costs: In April of 2015, the FASB issued guidance to clarify the presentation of debt issuance costs within the balance sheet. Additionally, the guidance requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this amendment. The guidance is effective for annual and interim periods beginning after December 15, 2015. The adoption of this guidance on January 1, 2016 did not materially impact the Company's financial condition, results of operations, or liquidity.

Accounting Pronouncements Pending Adoption

Revenue from Contracts with Customers: In May of 2014, the FASB issued guidance that requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In March of 2016, the FASB issued an amendment to this guidance to clarify the implementation of guidance on principal versus agent consideration. An additional amendment to clarify the implementation guidance on the identification of performance obligations and licensing was issued in April of 2016.

The guidance was initially effective for annual and interim reporting periods beginning on or after December 15, 2016. In August of 2015, the FASB issued guidance that defers the effective date by one year. The deferral causes the guidance to be effective for annual and interim reporting periods beginning on or after December 15, 2017, and must be applied either retrospectively or using the modified retrospective approach. Early adoption is permitted, but not before the original effective date. Management is evaluating the new guidance, but does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern: In August of 2014, the FASB issued guidance that requires management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued. The guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Amendments to Guidance on Classifying and Measuring Financial Instruments: In January of 2016, the FASB issued guidance that will require entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value. Any changes in fair value will be recognized in net income unless the investments qualify for a new practicability exception. This guidance also requires entities to recognize changes in instrument-specific credit risk related to financial liabilities measured under the fair value option in other comprehensive income. No changes were made to the guidance for classifying and measuring investments in debt securities and loans. This guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Leases: In February of 2016, the FASB issued guidance to increase transparency and comparability across entities for leasing arrangements. This guidance requires lessees to recognized assets and liabilities for most leases. For lessors, this guidance modifies the lease classification criteria and the accounting for sales-type and direct financing leases. In addition, this guidance clarifies criteria for the determination of whether a contract is or contains a lease. This guidance is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted. Management is evaluating the new guidance and the impact to the Company's financial condition, results of operations, and liquidity.

Contingent Put and Call Options in Debt Instruments: In March of 2016, the FASB issued final guidance clarifying the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. Entities are required to apply the guidance to existing debt instruments (or hybrid financial instruments that are determined to have a debt host) using a modified retrospective transition method as of the period of adoption. This guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted.

12

Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Equity Method Accounting: In March of 2016, the FASB issued final guidance to simplify the equity method of accounting. The guidance eliminates the requirement to retrospectively apply equity method accounting in previous periods when an investor initially obtains significant influence over an investee. This guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Accounting for Employee Share-based Payments: In March of 2016, the FASB issued guidance to simplify the accounting for employee share-based payment transactions. The guidance requires entities to recognize the income tax effects of awards in the income statement when the awards vest or are settled. In addition, the guidance allows entities to repurchase more of an employee's shares than it can under current guidance for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. This guidance is effective for annual and interim reporting periods beginning on or after December 15, 2016. Early adoption is permitted. Management is evaluating the new guidance, but does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

3. ACQUISITIONS

The National Bank & Trust Company of Sycamore

On March 8, 2016, the Company completed the acquisition of NI Bancshares Corporation ("NI Bancshares"), the holding company for The National Bank & Trust Company of Sycamore.

4. SECURITIES

Securities are classified as held-to-maturity, trading, or available-for-sale at the time of purchase. Securities classified as held-to-maturity are securities for which management has the intent and ability to hold to maturity and are stated at cost.

The Company's trading securities consist of diversified investment securities reported at fair value that are held in a grantor trust under deferred compensation arrangements in which plan participants may direct amounts earned to be invested in securities other than Company stock.

All other securities are classified as available-for-sale and are carried at fair value with unrealized gains and losses, net of related deferred income taxes, recorded in stockholders' equity as a separate component of accumulated other comprehensive loss.

A summary of the Company's securities portfolio by category and maturity is presented in the following tables.

Purchases and sales of securities are recognized on a trade date basis. Realized securities gains or losses are reported in net securities gains in the Condensed Consolidated Statements of Income. The cost of securities sold is based on the specific identification method. During the quarters ended March 31, 2016 and 2015 there were no material gross trading gains (losses). The following table presents net realized gains on available-for-sale securities for the quarters ended March 31, 2016 and 2015.

Securities Available-for-Sale Gains

Net realized gains	$	887		$	512

Accounting guidance requires that the credit portion of an OTTI charge be recognized through income. If a decline in fair value below carrying value is not attributable to credit deterioration and the Company does not intend to sell the security or believe it would not be more likely than not required to sell the security prior to recovery, the Company records the non-credit related portion of the decline in fair value in other comprehensive income.

The following table presents a rollforward of life-to-date OTTI recognized in earnings related to all securities available-for-sale held by the Company for the quarters ended March 31, 2016 and 2015. The majority of the beginning and ending balance of OTTI relates to CDOs currently held by the Company.

Substantially all of the Company's CMOs and other MBSs are either backed by U.S. government-owned agencies or issued by U.S. government-sponsored enterprises. Municipal securities are issued by municipal authorities, and the majority are supported by third party insurance or some other form of credit enhancement. Management does not believe any of these securities with unrealized losses as of March 31, 2016 represent OTTI related to credit deterioration. These unrealized losses are attributed to changes in interest rates and temporary market movements. The Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell them before recovery of their amortized cost basis, which may be at maturity.

The unrealized losses on CDOs as of March 31, 2016 reflect changes in market activity for these securities. Management does not believe these unrealized losses represent OTTI related to credit deterioration. In addition, the Company does not intend to sell the CDOs with unrealized losses within a short period of time, and the Company does not believe it is more likely than not that it will be required to sell them before recovery of their amortized cost basis, which may be at maturity. Significant judgment is required to calculate the fair value of the CDOs, all of which are pooled. For a detailed discussion of the CDO valuation methodology, see Note 14, "Fair Value."

Total loans	$	2,702	$	2,268	$	4,970	$	2,743	$	2,324	$	5,067

⁽¹⁾  These TDRs are included in non-accrual loans in the preceding tables.

TDRs are included in the calculation of the allowance for credit losses in the same manner as impaired loans. There were $729,000 in specific reserves related to TDRs as of March 31, 2016 and there were $758,000 in specific reserves related to TDRs as of December 31, 2015.

No loans were restructured during the quarters ended March 31, 2016 and 2015.

Accruing TDRs that do not perform in accordance with their modified terms are transferred to non-accrual. There were no material TDRs that defaulted within twelve months of the restructure date during the quarters ended March 31, 2016 and 2015.

26

A rollforward of the carrying value of TDRs for the quarters ended March 31, 2016 and 2015 is presented in the following table.

TDR Rollforward

Total TDRs	$	4,970		$	5,577

For TDRs to be removed from TDR status in the calendar year after the restructuring, the loans must (i) have an interest rate and terms that reflect market conditions at the time of restructuring, and (ii) be in compliance with the modified terms. Loans that were not restructured at market rates and terms, that are not in compliance with the modified terms, or for which there is a concern about the future ability of the borrower to meet its obligations under the modified terms, continue to be separately reported as restructured until paid in full or charged-off.

There were no material commitments to lend additional funds to borrowers with TDRs as of March 31, 2016 and December 31, 2015.

8.  BORROWED FUNDS

The following table summarizes the Company's borrowed funds by funding source.

Summary of Borrowed Funds

(Dollar amounts in thousands)

	As of
	March 31, 2016		December 31, 2015
Securities sold under agreements to repurchase	$	122,511	$	155,196
FHLB advances	262,500		9,900
Other borrowings	2,400		—
Total borrowed funds	$	387,411	$	165,096

Securities sold under agreements to repurchase are treated as financings and the obligations to repurchase securities sold are included as a liability in the Consolidated Statements of Financial Condition. Repurchase agreements are secured by U.S. treasury and agency securities. The securities underlying the agreements remain in the respective asset accounts.

The Bank is a member of the FHLB and has access to term financing from the FHLB. These advances are secured by designated assets that may include qualifying commercial real estate, residential and multi-family mortgages, home equity loans, and municipal and mortgage-backed securities. As of March 31, 2016, the Company held various 3-month FHLB advances with fixed interest rates of 0.5% and maturity dates that range from May 2, 2016 to June 1, 2016.

The Company hedges interest rates on borrowed funds using interest rate swaps through which the Company receives variable amounts and pays fixed amounts. See Note 12 "Derivative Instruments and Hedging Activities" for a detailed discussion of interest rate swaps.

				As of
	Issuance Date	Maturity Date	Interest Rate	March 31, 2016		December 31,  2015
Senior notes	November 2011	November 2016	5.875%	$	114,922	$	114,891
Subordinated notes	March 2006	April 2016	5.850%	38,500		38,499
Junior subordinated debentures:
First Midwest Capital Trust I ("FMCT")	November 2003	December 2033	6.950%	37,799		37,799
Great Lakes Statutory Trust II ("GLST II") (1)	December 2005	December 2035	L+1.400% (2)	4,320		4,296
Great Lakes Statutory Trust III ("GLST III") (1)	June 2007	September 2037	L+1.700% (2)	5,752		5,723
Total junior subordinated debentures				47,871		47,818
Total senior and subordinated debt				$	201,293	$	201,208

⁽¹⁾  The junior subordinated debentures related to GLST II and GLST III were assumed by the Company during 2014 through the acquisition of Great Lakes Financial Resources, Inc., the holding company for Great Lakes Bank. As of March 31, 2016 and December 31, 2015, these amounts include acquisition adjustments which resulted in a discount of $1.9 million to GLST II and $2.5 million to GLST III.

⁽²⁾  The interest rates are a variable rate based on the three-month LIBOR plus 1.400% and 1.700% for GLST II and GLST III, respectively.

On April 1, 2016 the $38.5 million in subordinated notes matured and were repaid by the Company. In November of 2016 $114.9 million of senior notes will mature.

Junior Subordinated Debentures

FMCT, GLST II and GLST III are Delaware statutory business trusts. These trusts were established for the purpose of issuing trust-preferred securities and lending the proceeds to the Company in return for junior subordinated debentures of the Company. The junior subordinated debentures are the sole assets of each trust. Therefore, each trust's ability to pay amounts due on the trust-preferred securities is solely dependent on the Company making payments on the related junior subordinated debentures. The trust-preferred securities are subject to mandatory redemption, in whole or in part, on repayment of the junior subordinated debentures at the stated maturity date or on redemption. The Company guarantees payments of distributions and redemptions on the trust-preferred securities on a limited basis.

Trust-preferred securities are included in Tier 1 capital of the Company for regulatory capital purposes. The statutory trusts qualify as VIEs for which the Company is not the primary beneficiary. Consequently, the accounts of those entities are not consolidated in the Company's financial statements.

Anti-dilutive shares not included in the computation of diluted EPS (1)	608			948

⁽¹⁾  This amount represents outstanding stock options for which the exercise price is greater than the average market price of the Company's common stock.

11. INCOME TAXES

The following table presents income tax expense and the effective income tax rate for the quarters ended March 31, 2016 and 2015.

Income Tax Expense

(Dollar amounts in thousands)

	Quarters Ended   March 31,
	2016			2015
Income before income tax expense	$	26,458		$	28,674
Income tax expense:
Federal income tax expense	$	7,101		$	7,076
State income tax expense	1,395			1,716
Total income tax expense	$	8,496		$	8,792
Effective income tax rate	32.1		%	30.7		%

Federal income tax expense and the related effective income tax rate are influenced by the amount of tax-exempt income derived from investment securities and BOLI in relation to pre-tax income and state income taxes. State income tax expense and the related effective tax rate are driven by the amount of state tax-exempt income in relation to pre-tax income and state tax rules related to consolidated/combined reporting and sourcing of income and expense.

The Company's accounting policies for the recognition of income taxes in the Consolidated Statements of Financial Condition and Income are included in Note 1, "Summary of Significant Accounting Policies" and Note 15, "Income Taxes" to the Consolidated Financial Statements in the Company's 2015 10-K.

12. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

In the ordinary course of business, the Company enters into derivative transactions as part of its overall interest rate risk management strategy. The significant accounting policies related to derivative instruments and hedging activities are presented in Note 1, "Summary of Significant Accounting Policies."

Fair Value Hedges

The Company hedges the fair value of fixed rate commercial real estate loans using interest rate swaps through which the Company pays fixed amounts and receives variable amounts. These derivative contracts are designated as fair value hedges.

Fair Value Hedges

(Dollar amounts in thousands)

	As of
	March 31, 2016			December 31, 2015
Gross notional amount outstanding	$	11,320		$	11,620
Derivative liability fair value	(612		)	(643		)
Weighted-average interest rate received	2.35		%	2.25		%
Weighted-average interest rate paid	6.35		%	6.36		%
Weighted-average maturity (in years)	1.73			1.97
Fair value of assets needed to settle derivative transactions (1)	$	633		$	665

⁽¹⁾  This amount represents the fair value if credit risk related contingent features were triggered.

Hedge ineffectiveness is recognized in other noninterest income in the Condensed Consolidated Statements of Income. For the quarters ended March 31, 2016 and 2015, gains or losses related to fair value hedge ineffectiveness were not material.

Cash Flow Hedges

As of March 31, 2016, the Company hedged $710.0 million of certain corporate variable rate loans using interest rate swaps through which the Company receives fixed amounts and pays variable amounts. The Company also hedged $510.0 million of borrowed funds using forward starting interest rate swaps through which the Company receives variable amounts and pays fixed amounts. These transactions allow the Company to add stability to net interest income and manage its exposure to interest rate movements. Forward starting interest rate swaps of $62.5 million and $200.0 million began during the second and third quarters of 2015, respectively, and mature during the same periods in 2019. The remaining forward starting interest rate swaps begin at various dates between June 2016 and March 2018 and mature between June 2019 and May 2020. These derivative contracts are designated as cash flow hedges.

Cash Flow Hedges

(Dollar amounts in thousands)

	As of
	March 31, 2016			December 31, 2015
Gross notional amount outstanding	$	1,220,000		$	1,220,000
Derivative asset fair value	17,121			4,787
Derivative liability fair value	(17,009		)	(8,950		)
Weighted-average interest rate received	1.31		%	1.24		%
Weighted-average interest rate paid	0.90		%	0.75		%
Weighted-average maturity (in years)	3.56			3.91

The effective portion of gains or losses on cash flow hedges is recorded in accumulated other comprehensive loss on an after-tax basis and is subsequently reclassified to interest income or expense in the period that the forecasted hedge impacts earnings. Hedge effectiveness is determined using a regressionanalysis at the inception of the hedge relationship and on an ongoing basis. For the quarters ended March 31, 2016 and 2015, there were no material gains or losses related to cash flow hedge ineffectiveness. As of March 31, 2016, the Company estimates that $3.9 million will be reclassified from accumulated other comprehensive loss as an increase to interest income over the next twelve months.

30

Other Derivative Instruments

The Company also enters into derivative transactions with its commercial customers and simultaneously enters into an offsetting interest rate derivative transaction with a third party. This transaction allows the Company's customers to effectively convert a variable rate loan into a fixed rate loan. Due to the offsetting nature of these transactions, the Company does not apply hedge accounting treatment. The Company's credit exposure on these derivative transactions results primarily from counterparty credit risk. The credit valuation adjustment ("CVA") is a fair value adjustment to the derivative to account for this risk. As of March 31, 2016 and December 31, 2015, the CVA was not material. Transaction fees related to commercial customer derivative instruments of $3.2 million and $662,000 were recorded in noninterest income for the quarters ended March 31, 2016 and 2015, respectively.

Other Derivative Instruments

(Dollar amounts in thousands)

	As of
	March 31, 2016			December 31, 2015
Gross notional amount outstanding	$	1,023,359		$	853,385
Derivative asset fair value	23,212			11,446
Derivative liability fair value	(23,212		)	(11,446		)
Fair value of assets needed to settle derivative transactions (1)	23,743			11,939

⁽¹⁾  This amount represents the fair value if credit risk related contingent features were triggered.

The Company occasionally enters into risk participation agreements with counterparty banks to transfer or assume a portion of the credit risk related to customer transactions. The amounts of these instruments were not material for any periods presented. The Company had no other derivative instruments as of March 31, 2016 and December 31, 2015. The Company does not enter into derivative transactions for purely speculative purposes.

Credit Risk

Derivative instruments are inherently subject to credit risk, which represents the Company's risk of loss when the counterparty to a derivative contract fails to perform according to the terms of the agreement. Credit risk is managed by limiting and collateralizing the aggregate amount of net unrealized losses by transaction, monitoring the size and the maturity structure of the derivatives, and applying uniform credit standards. Company policy establishes limits on credit exposure to any single counterparty. In addition, the Company established bilateral collateral agreements with derivative counterparties that provide for exchanges of marketable securities or cash to collateralize either party's net losses above a stated minimum threshold. As of March 31, 2016 and December 31, 2015, these collateral agreements covered 100% of the fair value of the Company's outstanding fair value hedges. Derivative assets and liabilities are presented gross, rather than net, of pledged collateral amounts.

31

Certain derivative instruments are subject to master netting agreements with counterparties. The Company records these transactions at their gross fair values and does not offset derivative assets and liabilities in the Consolidated Statements of Financial Condition. The following table presents the fair value of the Company's derivatives and offsetting positions as of March 31, 2016 and December 31, 2015.

Fair Value of Offsetting Derivatives

	As of March 31, 2016						As of December 31, 2015
	Assets			Liabilities			Assets			Liabilities

⁽¹⁾  Included in other assets or other liabilities in the Consolidated Statements of Financial Condition.

As of March 31, 2016 and December 31, 2015, the Company's derivative instruments generally contained provisions that require the Company's debt to remain above a certain credit rating by each of the major credit rating agencies or that the Company maintain certain capital levels. If the Company's debt were to fall below that credit rating or the Company's capital were to fall below the required levels, it would be in violation of those provisions, and the counterparties to the derivative instruments could terminate the swap transaction and demand cash settlement of the derivative instrument in an amount equal to the derivative liability fair value. As of March 31, 2016 and December 31, 2015 the Company was not in violation of these provisions.

32

13. COMMITMENTS, GUARANTEES, AND CONTINGENT LIABILITIES

Credit Commitments and Guarantees

In the normal course of business, the Company enters into a variety of financial instruments with off-balance sheet risk to meet the financing needs of its customers and to conduct lending activities, including commitments to extend credit and standby and commercial letters of credit. These instruments involve elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Statements of Financial Condition.

Contractual or Notional Amounts of Financial Instruments

(Dollar amounts in thousands)

	As of
	March 31, 2016		December 31, 2015
Commitments to extend credit:
Commercial, industrial, and agricultural	$	1,396,016	$	1,303,056
Commercial real estate	378,063		366,250
Home equity	368,671		352,114
Other commitments (1)	215,253		203,121
Total commitments to extend credit	$	2,358,003	$	2,224,541
Standby letters of credit	$	93,695	$	100,610
Recourse on assets sold:
Unpaid principal balance of loans sold	$	193,704	$	196,389
Carrying value of recourse obligation (2)	92		87

⁽¹⁾  Other commitments includes installment and overdraft protection program commitments.

⁽²⁾  Included in other liabilities in the Consolidated Statements of Financial Condition.

Commitments to extend credit are agreements to lend funds to a customer, subject to contractual terms and covenants. Commitments generally have fixed expiration dates or other termination clauses, variable interest rates, and fee requirements, when applicable. Since many of the commitments are expected to expire without being drawn, the total commitment amounts do not necessarily represent future cash flow requirements.

In the event of a customer's non-performance, the Company's credit loss exposure is equal to the contractual amount of the commitments. The credit risk is essentially the same as extending loans to customers. The Company uses the same credit policies for credit commitments as its loans and minimizes exposure to credit loss through various collateral requirements.

Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby letters of credit generally are contingent on the failure of the customer to perform according to the terms of the contract with the third party and are often issued in favor of a municipality where construction is taking place to ensure the borrower adequately completes the construction.

The maximum potential future payments guaranteed by the Company under standby letters of credit arrangements are equal to the contractual amount of the commitment. If a commitment is funded, the Company may seek recourse through the liquidation of the underlying collateral, including real estate, production plants and property, marketable securities, or receipt of cash.

As a result of the sale of certain 1-4 family mortgage loans, the Company is contractually obligated to repurchase any non-performing loans or loans that do not meet underwriting requirements at recorded value. In accordance with the sales agreements, there is no limitation to the maximum potential future payments or expiration of the Company's recourse obligation. There were no material loan repurchases during the quarters ended March 31, 2016 and 2015.

Legal Proceedings

In the ordinary course of business, there were certain legal proceedings pending against the Company and its subsidiaries at March 31, 2016. While the outcome of any legal proceeding is inherently uncertain, based on information currently available, the Company's management does not expect that any liabilities arising from pending legal matters will have a material adverse effect on the Company's financial position, results of operations, or liquidity.

33

14. FAIR VALUE

Fair value represents the amount expected to be received to sell an asset or paid to transfer a liability in its principal or most advantageous market in an orderly transaction between market participants at the measurement date. In accordance with fair value accounting guidance, the Company measures, records, and reports various types of assets and liabilities at fair value on either a recurring or non-recurring basis in the Consolidated Statements of Financial Condition. Those assets and liabilities are presented below in the sections titled "Assets and Liabilities Required to be Measured at Fair Value on a Recurring Basis" and "Assets and Liabilities Required to be Measured at Fair Value on a Non-Recurring Basis."

Other assets and liabilities are not required to be measured at fair value in the Consolidated Statements of Financial Condition, but must be disclosed at fair value. See the "Fair Value Measurements of Other Financial Instruments" section of this note. Any aggregation of the estimated fair values presented in this note does not represent the value of the Company.

Depending on the nature of the asset or liability, the Company uses various valuation methodologies and assumptions to estimate fair value. GAAP provides a three-tiered fair value hierarchy based on the inputs used to measure fair value. The hierarchy is defined as follows:

• Level 1 - Quoted prices in active markets for identical assets or liabilities.

• Level 2 - Observable inputs other than level 1 prices, such as quoted prices for similar instruments, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

• Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These inputs require significant management judgment or estimation, some of which use model-based techniques and may be internally developed.

Assets and liabilities are assigned to a level within the fair value hierarchy based on the lowest level of significant input used to measure fair value. Assets and liabilities may change levels within the fair value hierarchy due to market conditions or other circumstances. Those transfers are recognized on the date of the event that prompted the transfer. There were no transfers of assets or liabilities between levels of the fair value hierarchy during the periods presented.

34

Assets and Liabilities Required to be Measured at Fair Value on a Recurring Basis

The following table provides the fair value for assets and liabilities required to be measured at fair value on a recurring basis in the Consolidated Statements of Financial Condition by level in the fair value hierarchy.

The following sections describe the specific valuation techniques and inputs used to measure financial assets and liabilities at fair value.

Trading Securities

The Company's trading securities consist of diversified investment securities held in a grantor trust and are invested in money market and mutual funds. The fair value of these money market and mutual funds is based on quoted market prices in active exchange markets and is classified in level 1 of the fair value hierarchy.

Securities Available-for-Sale

The Company's securities available-for-sale are primarily fixed income instruments that are not quoted on an exchange, but may be traded in active markets. The fair values for these securities are based on quoted prices in active markets or market prices for similar securities obtained from external pricing services or dealer market participants and are classified in level 2 of the fair value hierarchy. The fair value of U.S. treasury securities is based on quoted market prices in active exchange markets and is classified in level 1 of the fair value hierarchy. Quarterly, the Company evaluates the methodologies used by its external pricing services to estimate the fair value of these securities to determine whether the valuations represent an exit price in the Company's principal markets.

CDOs are classified in level 3 of the fair value hierarchy. The Company estimates the fair values for each CDO using discounted cash flow analyses with the assistance of a structured credit valuation firm. This methodology is based on credit analysis and historical financial data for each of the issuers underlying the CDOs (the "Issuers"). These estimates are highly subjective and sensitive to several significant, unobservable inputs. The cash flows for each Issuer are then discounted to present values using LIBOR plus an adjustment to reflect the impact of market factors. Finally, the discounted cash flows for each Issuer are aggregated to derive the estimated fair value for the specific CDO.

35

The following table presents the ranges of significant, unobservable inputs calculated using the weighted average of the Issuers used by the Company as of March 31, 2016 and December 31, 2015.

Significant Unobservable Inputs Used in the Valuation of CDOs

	As of
	March 31, 2016				December 31, 2015
Probability of prepayment	1.8	%	-	15.1%	1.8	%	-	15.1%
Probability of default	18.6	%	-	49.7%	19.1	%	-	32.6%
Loss given default	92.8	%	-	98.4%	93.8	%	-	97.1%
Probability of deferral cure	15.2	%	-	63.5%	15.2	%	-	63.1%

Most Issuers have the right to prepay the securities on the fifth anniversary of issuance and under other limited circumstances. To estimate prepayments, a credit analysis of each Issuer is performed to estimate its ability and likelihood to fund a prepayment. If a prepayment occurs, the Company receives cash equal to the par value for the portion of the CDO associated with that Issuer.

The likelihood that an Issuer who is currently deferring payment on the securities will pay all deferred amounts and remain current thereafter is based on an analysis of the Issuer's asset quality, leverage ratios, and other measures of financial viability.

The impact of changes in these key inputs could result in a significantly higher or lower fair value measurement for each CDO. The timing of the default, the magnitude of the default, and the timing and magnitude of the cure probability are directly interrelated. Defaults that occur sooner and/or are greater than anticipated have a negative impact on the valuation. In addition, a high cure probability assumption has a positive effect on the fair value, and, if a cure event takes place sooner than anticipated, the impact on the valuation is also favorable.

Management monitors the valuation results of each CDO on a semi-annual basis, which includes an analysis of historical pricing trends for these types of securities, overall economic conditions (such as tracking LIBOR curves), and the performance of the Issuers' industries. Annually, management validates significant assumptions by reviewing detailed back-testing performed by the structured credit valuation firm.

A rollforward of the carrying value of CDOs for the quarters ended March 31, 2016 and 2015 is presented in the following table.

Carrying Value of CDOs

MSRs

The Company services loans for others totaling $600.8 million as of March 31, 2016 and $242.9 million as of December 31, 2015. These loans are owned by third parties and are not included in the Consolidated Statements of Financial Condition. As of March 31, 2016, loans serviced for others includes approximately $350.0 million of loans, the servicing of which transitioned from NI Bancshares to the Company as a result of the NI Bancshares acquisition, and resulted in an additional $3.1 million of MSRs. Additional information regarding the NI Bancshares transaction is presented in Note 3, "Acquisitions."

The Company determines the fair value of MSRs by estimating the present value of expected future cash flows associated with the mortgage loans being serviced and classifies them in level 3 of the fair value hierarchy. The following table presents the ranges of significant, unobservable inputs used by the Company to determine the fair value of MSRs as of March 31, 2016.

Significant Unobservable Inputs Used in the Valuation of MSRs

	As of
	March 31, 2016				December 31, 2015
Prepayment speed	10.9	%	-	23.0%	10.1	%	-	20.9%
Maturity (months)	4		-	79	6		-	86
Discount rate	9.5	%	-	13.0%	9.5	%	-	13.0%

The impact of changes in these key inputs could result in a significantly higher or lower fair value measurement for MSRs. Significant increases in expected prepayment speeds and discount rates have negative impacts on the valuation. Higher maturity assumptions have a favorable effect on the estimated fair value.

A rollforward of the carrying value of MSRs for the quarters ended March 31, 2016 and 2015 is presented in the following table.

⁽²⁾  Primarily represents changes in expected future cash flows due to payoffs and paydowns.

Derivative Assets and Derivative Liabilities

The Company enters into interest rate swaps and derivative transactions with commercial customers. These derivative transactions are executed in the dealer market, and pricing is based on market quotes obtained from the counterparties. The market quotes were developed using market observable inputs, which primarily include LIBOR. Therefore, derivatives are classified in level 2 of the fair value hierarchy. For its derivative assets and liabilities, the Company also considers non-performance risk, including the likelihood of default by itself and its counterparties, when evaluating whether the market quotes from the counterparty are representative of an exit price.

⁽¹⁾  Includes impaired loans with charge-offs and impaired loans with a specific reserve during the periods presented.

⁽²⁾  Includes OREO with fair value adjustments subsequent to initial transfer that occurred during the periods presented.

⁽³⁾  Included in other assets in the Consolidated Statements of Financial Condition.

⁽⁴⁾  Included in premises, furniture, and equipment in the Consolidated Statements of Financial Condition.

Collateral-Dependent Impaired Loans

Certain collateral-dependent impaired loans are subject to fair value adjustments to reflect the difference between the carrying value of the loan and the value of the underlying collateral. The fair values of collateral-dependent impaired loans are primarily determined by current appraised values of the underlying collateral. Based on the age and/or type, appraisals may be adjusted in the range of 0% to 15%. In certain cases, an internal valuation may be used when the underlying collateral is located in areas where comparable sales data is limited or unavailable. Accordingly, collateral-dependent impaired loans are classified in level 3 of the fair value hierarchy.

Collateral-dependent impaired loans for which the fair value is greater than the recorded investment are not measured at fair value in the Consolidated Statements of Financial Condition and are not included in this disclosure.

OREO

The fair value of OREO is measured using the current appraised value of the properties. In certain circumstances, a current appraisal may not be available or may not represent an accurate measurement of the property's fair value due to outdated market information or other factors. In these cases, the fair value is determined based on the lower of the (i) most recent appraised value, (ii) broker price opinion, (iii) current listing price, or (iv) signed sales contract. Given these valuation methods, OREO is classified in level 3 of the fair value hierarchy.

Loans Held-for-Sale

As of March 31, 2016, loans held-for-sale consists of 1-4 family mortgage loans, which were originated with the intent to sell. These loans were recorded in the held-for-sale category at the contract price and, accordingly, are classified in level 3 of the fair value hierarchy. As of December 31, 2015, loans held-for-sale consists of 1-4 family mortgage loans, which were originated with the intent to sell, and a commercial real estate loan.

Assets Held-for-Sale

Assets held-for-sale as of March 31, 2016 and December 31, 2015 consists of twelve former branches that are no longer in operation and seven parcels of land previously purchased for expansion. These properties are being actively marketed and were transferred into the held-for-sale category at the lower of their fair value, as determined by a current appraisal. Based on these valuation methods, they are classified in level 3 of the fair value hierarchy.

38

Financial Instruments Not Required to be Measured at Fair Value

For certain financial instruments that are not required to be measured at fair value in the Consolidated Statements of Financial Condition, the Company must disclose the estimated fair values and the level within the fair value hierarchy as shown in the following table.

Accrued interest payable	2	5,446		5,446		2,175		2,175

Management uses various methodologies and assumptions to determine the estimated fair values of the financial instruments in the table above. The fair value estimates are made at a discrete point in time based on relevant market information and consider management's judgments regarding future expected economic conditions, loss experience, and specific risk characteristics of the financial instruments.

Short-Term Financial Assets and Liabilities - For financial instruments with a shorter-term or with no stated maturity, prevailing market rates, and limited credit risk, the carrying amounts approximate fair value. Those financial instruments include cash and due from banks, interest-bearing deposits in other banks, accrued interest receivable, and accrued interest payable.

Securities Held-to-Maturity - The fair value of securities held-to-maturity is estimated using the present value of expected future cash flows of the remaining maturities of the securities.

FHLB and FRB Stock - The carrying amounts approximate fair value as the stock is non-marketable.

Loans - Loans includes the FDIC indemnification asset and net loans, which consists of loans held-for-investment, acquired loans, covered loans, and the allowance for loan losses. The fair value of loans is estimated using the present value of the expected future cash flows of the remaining maturities of the loans. Prepayment assumptions that consider the Company's historical experience and current economic and lending conditions were included. The discount rate was based on the LIBOR yield curve with adjustments for liquidity and credit risk inherent in the loans.

The fair value of the covered loan portfolio is determined by discounting the expected future cash flows at a market interest rate, which is derived from LIBOR swap rates over the life of those loans. The expected future cash flows are derived from the contractual terms of the covered loans, net of any projected credit losses. For valuation purposes, these loans are placed into groups with similar characteristics and risk factors, where appropriate. The timing and amount of credit losses for each group are estimated using historical default and loss experience, current collateral valuations, borrower credit scores, and internal risk ratings. For individually significant loans or credit relationships, the estimated fair value is determined by a specific loan level review utilizing appraised values for collateral and projections of the timing and amount of expected future cash flows.

39

Investment in BOLI - The fair value of BOLI approximates the carrying amount as both are based on each policy's respective cash surrender value ("CSV"), which is the amount the Company would receive from liquidation of these investments. The CSV is derived from monthly reports provided by the managing brokers and is determined using the Company's initial insurance premium and earnings of the underlying assets, offset by management fees.

Other Interest-Earning Assets - The fair value of other interest-earning assets is estimated using the present value of the expected future cash flows of the remaining maturities of the assets.

Deposits - The fair values disclosed for demand deposits, savings deposits, NOW accounts, and money market deposits are equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The fair value for fixed-rate time deposits was estimated using the expected future cash flows discounted based on the LIBOR yield curve, plus or minus the spread associated with current pricing.

Borrowed Funds- The fair value of FHLB advances is estimated by discounting the agreements based on maturities using the rates currently offered for FHLB advances of similar remaining maturities adjusted for prepayment penalties that would be incurred if the borrowings were paid off on the measurement date. The carrying amounts of securities sold under agreements to repurchase approximate their fair value due to their short-term nature.

Senior and Subordinated Debt - The fair value of senior and subordinated debt is determined using quoted market prices.

Commitments to Extend Credit and Letters of Credit - The Company estimated the fair value of lending commitments outstanding to be immaterial based on (i) the limited interest rate exposure of the commitments outstanding due to their variable nature, (ii) the short-term nature of the commitment periods, (iii) termination clauses provided in the agreements, and (iv) the market rate of fees charged.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

INTRODUCTION

First Midwest Bancorp, Inc. is a bank holding company headquartered in the Chicago suburb of Itasca, Illinois with operations throughout the Chicago metropolitan area as well as northwest Indiana, central and western Illinois, and eastern Iowa through over 110 banking locations. Our principal subsidiary is First Midwest Bank (the "Bank"), which provides a broad range of banking, treasury, and wealth management products and services to commercial and industrial, commercial real estate, municipal, and consumer customers. We are committed to meeting the financial needs of the people and businesses in the communities where we live and work by providing customized banking solutions, quality products, and innovative services that fulfill those financial needs.

The following discussion and analysis is intended to address the significant factors affecting our Condensed Consolidated Statements of Income for the quarters ended March 31, 2016 and 2015 and Consolidated Statements of Financial Condition as of March 31, 2016 and December 31, 2015. When we use the terms "First Midwest," the "Company," "we," "us," and "our," we mean First Midwest Bancorp, Inc. and its consolidated subsidiaries. When we use the term "Bank," we are referring to our wholly owned banking subsidiary, First Midwest Bank. Management's discussion and analysis should be read in conjunction with the consolidated financial statements, accompanying notes thereto, and other information presented in Item 1 of this Form 10-Q, as well as in our 2015 Annual Report on Form 10-K ("2015 10-K"). The results of operations for the quarter ended March 31, 2016 are not necessarily indicative of future results.

Our results of operations are affected by various factors, many of which are beyond our control, including interest rates, local and national economic conditions, business spending, consumer confidence, legislative and regulatory changes, certain seasonal factors, and changes in real estate and securities markets. Our management evaluates performance using a variety of qualitative and quantitative metrics. The primary quantitative metrics used by management include:

• Net Interest Income - Net interest income, our primary source of revenue, equals the difference between interest income and fees earned on interest-earning assets and interest expense incurred on interest-bearing liabilities.

• Net Interest Margin - Net interest margin equals tax-equivalent net interest income divided by total average interest-earning assets.

• Noninterest Income - Noninterest income is the income we earn from fee-based revenues, investment in bank-owned life insurance ("BOLI"), other income, and non-operating revenues.

• Noninterest Expense - Noninterest expense is the expense we incur to operate the Company, which includes salaries and employee benefits, net occupancy and equipment, professional services, and other costs.

• Asset Quality - Asset quality represents an estimation of the quality of our loan portfolio, including an assessment of the credit risk related to existing and potential loss exposure, and can be evaluated using a number of quantitative measures, such as non-performing loans to total loans.

• Regulatory Capital - Our regulatory capital is classified in one of the following tiers: (i) Common Equity Tier 1 capital ("CET1"), which consists of common equity and retained earnings, less goodwill and other intangible assets and a portion of disallowed deferred tax assets, (ii) Tier 1 capital, which consists of CET1 and qualifying trust-preferred securities and the remaining portion of disallowed deferred tax assets, and (iii) Tier 2 capital, which includes qualifying subordinated debt and the allowance for credit losses, subject to limitations.

Unless otherwise stated, all earnings per common share data included in this section and throughout the remainder of this discussion are presented on a diluted basis.

As of March 31, 2016, the Company and the Bank each had total assets of approximately $10.7 billion. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") and its implementing regulations impose various additional requirements on bank holding companies and banks with $10.0 billion or more in total consolidated assets. As a general matter, the Company and the Bank are not immediately subject to these additional requirements when they exceed $10 billion in assets; instead, the Company and the Bank will be subject to these various requirements over various dates. For a discussion of the impact that the Dodd-Frank Act and its implementing regulations will have on the Company and the Bank now that they have each exceeded $10.0 billion in total consolidated assets, see the "Supervision and Regulation" section in Item 1, "Business" and Item 1A, "Risk Factors" in the Company's 2015 10-K.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q may contain certain "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. In some cases, forward-looking statements can be identified by the use of words such as "may," "might," "will," "would," "should," "could," "expect," "plan," "intend," "anticipate," "believe," "estimate," "predict," "probable," "potential," "possible," "target," "continue," "look forward," "assume," and words of similar import. Forward-looking statements

41

are not historical facts but instead express only management's beliefs regarding future results or events, many of which, by their nature, are inherently uncertain and outside of management's control. It is possible that actual results and events may differ, possibly materially, from the anticipated results or events indicated in these forward-looking statements. Forward-looking statements are not guarantees of future performance, and we caution you not to place undue reliance on these statements. Forward-looking statements are made only as of the date of this report, and we undertake no obligation to update any forward-looking statements contained in this report to reflect new information or events or conditions after the date hereof.

Forward-looking statements may be deemed to include, among other things, statements relating to our future financial performance, the performance of our loan or securities portfolio, the expected amount of future credit reserves or charge-offs, corporate strategies or objectives, anticipated trends in our business, regulatory developments, acquisition transactions, including estimated synergies, cost savings and financial benefits of pending or consummated transactions, and growth strategies, including possible future acquisitions. These statements are subject to certain risks, uncertainties and assumptions. For a discussion of these risks, uncertainties, and assumptions, you should refer to the sections entitled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in this report and in our 2015 10-K, as well as our subsequent filings made with the Securities and Exchange Commission ("SEC"). However, these risks and uncertainties are not exhaustive. Other sections of this report describe additional factors that could adversely impact our business and financial performance.

NON-GAAP FINANCIAL INFORMATION

The Company's accounting and reporting policies conform to U.S. generally accepted accounting principles ("GAAP") and general practice within the banking industry. As a supplement to GAAP, the Company provides non-GAAP performance results, which the Company believes are useful because they assist investors in assessing the Company's operating performance. These include, but are not limited to, earnings per share, excluding acquisition and integration related expenses, total non-interest expense, excluding acquisition and integration related expenses, tax-equivalent net interest income (including its individual components), tax-equivalent net interest margin, the efficiency ratio, tangible common equity to tangible assets, tangible common equity, excluding accumulated other comprehensive loss, to tangible assets, tangible common equity to risk-weighted assets, and return on average tangible common equity. Although intended to enhance investors' understanding of the Company's business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP.

CRITICAL ACCOUNTING ESTIMATES

Our accounting and reporting policies conform to GAAP and general practices within the banking industry. Application of GAAP requires management to make estimates, assumptions, and judgments based on information available as of the date of the financial statements that affect the amounts reported in the financial statements and accompanying notes. Critical accounting estimates are those estimates that management believes are the most important to our financial position and results of operations. Future changes in information may impact these estimates, assumptions, and judgments, which may have a material effect on the amounts reported in the financial statements.

For additional information regarding critical accounting estimates, see the "Summary of Significant Accounting Policies," presented in Note 1 to the Consolidated Financial Statements and the section titled "Critical Accounting Estimates" in Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Company's 2015 10-K. There have been no significant changes in the Company's application of critical accounting estimates related to the allowance for credit losses, valuation of securities, income taxes, and goodwill and other intangible assets since December 31, 2015.

⁽¹⁾  These amounts and ratios exclude loans and OREO acquired through the Company's Federal Deposit Insurance Corporation ("FDIC")-assisted transactions subject to loss sharing agreements ("covered loans" and "covered OREO"). For a discussion of covered loans, see Note 1 and Note 6 of "Notes to the Condensed Consolidated Financial Statements" in Part I, Item 1 of this Form 10-Q. Asset quality, including covered loans and covered OREO, is included in the section of this Item 2 titled "Loan Portfolio and Credit Quality."

⁽²⁾  This ratio includes acquired loans that are recorded at fair value through an acquisition adjustment, which incorporates credit risk as of the acquisition date with no allowance for credit losses being established at that time. As the acquisition adjustment is accreted into income over future periods, an allowance for credit losses is established as necessary to reflect credit deterioration. A discussion of the allowance for acquired loan losses and the related acquisition adjustment is presented in the section titled "Loan Portfolio and Credit Quality."

Net income for the first quarter of 2016 was $18.0 million, or $0.23 per share, compared to $19.9 million, or $0.26 per share, for the first quarter of 2015. Performance for the first quarter of 2016 was impacted by acquisition and integration related pre-tax expenses of $5.0 million. Excluding these expenses, net income for the first quarter of 2016 was $21.0 million, or $0.27 per share compared to $0.26 per share for the first quarter of 2015. The increase in net income and earnings per share reflects the benefit of acquisitions completed in the fourth quarter of 2015 and first quarter of 2016, loan growth, and growth in fee-based revenues. A discussion of net interest income, noninterest income, and noninterest expense is presented in the following section titled "Earnings Performance."

Total loans of $7.8 billion grew $660.8 million, or 9.2%, from December 31, 2015. This growth was driven by the acquisition of NI Bancshares, which represents $395.8 million of loans at March 31, 2016, and strong sales production from the corporate and consumer lending teams.

44

Total non-performing assets, excluding covered loans and covered OREO, increased by $7.0 million, or 11.2%, from December 31, 2015, and decreased by $12.5 million, or 15.3%, from March 31, 2015. See the "Loan Portfolio and Credit Quality" section below for further discussion of our loan portfolio, non-accrual loans, 90 days or more past due loans, TDRs, and OREO.

EARNINGS PERFORMANCE

Net Interest Income

Net interest income is our primary source of revenue and is impacted by interest rates and the volume and mix of interest-earning assets and interest-bearing liabilities. The accounting policies for the recognition of interest income on loans, securities, and other interest-earning assets are presented in Note 1 to the Consolidated Financial Statements of our 2015 10-K.

Our accounting and reporting policies conform to GAAP and general practices within the banking industry. For purposes of this discussion, both net interest income and net interest margin have been adjusted to a fully tax-equivalent basis to more appropriately compare the returns on certain tax-exempt loans and securities to those on taxable interest-earning assets. Although we believe that these non-GAAP financial measures enhance investors' understanding of our business and performance, they should not be considered an alternative to GAAP. The effect of this adjustment is at the bottom of Table 2.

Table 2 summarizes our average interest-earning assets and interest-bearing liabilities for the quarters ended March 31, 2016and 2015, the related interest income and interest expense for each earning asset category and funding source, and the average interest rates earned and paid. Table 2 also details differences in interest income and expense from the prior quarter and the extent to which any changes are attributable to volume and rate fluctuations.

⁽¹⁾  Interest income and yields are presented on a tax-equivalent basis, assuming a federal income tax rate of 35%.

⁽²⁾  Non-accrual loans, including covered loans, which totaled $31.9 million as of March 31, 2016 and $52.6 million as of March 31, 2015, are included in loans for purposes of this analysis. Additional detail regarding non-accrual loans is presented in the following section of this Item 2 titled "Non-performing Assets and Performing Potential Problem Loans."

⁽³⁾  This item includes covered loans and the related FDIC indemnification asset. For additional discussion, see Note 1 and Note 6 of "Notes to the Condensed Consolidated Financial Statements" in Part I, Item 1 of this Form 10-Q.

For the first quarter of 2016, total average interest-earning assets rose by $604.3 million from the first quarter of 2015, driven by organic loan growth, purchased securities, and assets acquired in the NI Bancshares transaction during first quarter of 2016.

Total average funding sources increased by $537.4 million from the first quarter of 2015. The increase resulted primarily from deposits acquired from the NI Bancshares transaction late in the first quarter of 2016 and the Peoples Bancorp, Inc. ("Peoples") transaction late in the fourth quarter of 2015, and the addition of $262.5 million of FHLB advances during the first quarter of 2016.

46

Tax-equivalent net interest margin for the current quarter was 3.66%, decreasing 13 basis points from the first quarter of 2015, due primarily to lower accretion on acquired loans, lower covered loan income, and the continued shift to floating rate loans, which more than offset the redeployment of other interest-earning assets into higher yielding loans and securities.

Net interest income increased by 5.1% from the first quarter of 2015, reflecting the increase in average loans of 9.0% from the same period.

Acquired loan accretion contributed $1.4 million and $2.3 million to net interest income for the first quarter of 2016 and the first quarter of 2015, respectively.

Noninterest Income

A summary of noninterest income for the quarters ended March 31, 2016 and 2015 are presented in the following table.

Total noninterest income	$	35,926	$	31,101	15.5

⁽¹⁾  Card-based fees consist of debit and credit card interchange fees for processing transactions as well as various fees on both customer and non-customer automated teller machine ("ATM") and point-of-sale transactions processed through the ATM and point-of-sale networks.

⁽²⁾  Merchant servicing fees are included in other service charges, commissions, and fees in the Condensed Consolidated Statements of Income. The related merchant card expense is included in noninterest expense for each period presented.

⁽³⁾  Other income consists of various items, including BOLI income, safe deposit box rentals, miscellaneous recoveries, and gains on the sales of various assets.

⁽⁴⁾  For a discussion of this item, see the section of this Item 2 titled "Investment Portfolio Management."

Total noninterest income of $35.9 million increased by 15.5% from the first quarter of 2015. Total fee-based revenues of $33.6 million grew 17.3% compared to the first quarter of 2015, reflecting growth across all categories.

Continued sales of fiduciary and investment advisory services to new and existing customers drove the rise in wealth management fees compared to the first quarter of 2015. In addition, the NI Bancshares transaction, which added over $700.0 million in trust assets under management, contributed approximately $260,000 to wealth management fees in the first quarter of 2016. As of March 31, 2016 trust assets under management totaled $8.1 billion.

Mortgage banking income resulted from sales of $38.7 million of 1-4 family mortgage loans in the secondary market during the first quarter of 2016 compared to $34.5 million in the first quarter of 2015.

The increase in other service charges, commissions, and fees compared to the first quarter of 2015 was due primarily to the sales of capital market products to commercial clients and gains realized on the sale of equipment financing contracts originated by First Midwest Equipment Finance.

⁽¹⁾  These line items are included in other expense in the Condensed Consolidated Statements of Income.

⁽²⁾  The related merchant servicing fees are included in noninterest income for each period presented.

⁽³⁾  The efficiency ratio expresses noninterest expense, excluding OREO expense, as a percentage of tax-equivalent net interest income plus total fee-based revenues, other income, and tax-equivalent adjusted BOLI income. BOLI income totaled $866,000 and $883,000 for the quarters ended March 31, 2016 and 2016, respectively. In addition, acquisition and integration related expenses of $5.0 million are excluded from the efficiency ratio for the first quarter of 2016.

Total noninterest expense increased by 6.8% compared to the first quarter of 2015, excluding acquisition and integration related expenses. This increase was driven primarily by salaries and employee benefits and professional services costs associated with merit increases and organizational growth needs, as well as the acquisitions of Peoples and NI Bancshares.

Compared to the first quarter of 2015, total noninterest expense was impacted by operating costs of the 10 banking locations acquired in the NI Bancshares transaction late in the first quarter of 2016, and the impact of the 2 banking locations acquired in the Peoples transaction in the fourth quarter of 2015. These costs primarily occurred within salaries and employee benefits expense and other expenses.

Net occupancy and equipment expense decreased compared to the first quarter of 2015 due to lower weather-related expenses and maintenance costs.

The rise in advertising and promotions expense from the first quarter of 2015 reflects the timing of certain advertising costs.

Compared to the first quarter of 2015, net OREO expense decreased due to reduced valuation adjustments and lower operating expenses. These reductions were partially offset by net losses on sales of OREO properties realized during the first quarter of 2016, compared to net gains on sales of OREO properties realized during the first quarter of 2015.

Income Taxes

Our provision for income taxes includes both federal and state income tax expense. An analysis of the provision for income taxes is detailed in the following table.

Table 5

Income Tax Expense Analysis

(Dollar amounts in thousands)

	Quarters Ended   March 31,
	2016			2015
Income before income tax expense	$	26,458		$	28,674
Income tax expense:
Federal income tax expense	$	7,101		$	7,076
State income tax expense	1,395			1,716
Total income tax expense	$	8,496		$	8,792
Effective income tax rate	32.1		%	30.7		%

Federal income tax expense and the related effective income tax rate are influenced by the amount of tax-exempt income derived from investment securities and BOLI in relation to pre-tax income and state income taxes. State income tax expense and the related effective tax rate are driven by the amount of state tax-exempt income in relation to pre-tax income and state tax rules related to consolidated/combined reporting and sourcing of income and expense.

The decrease in total income tax expense for the quarter ended March 31, 2016 compared to the same period in 2015 resulted primarily from lower levels of income subject to tax at statutory rates. The increase in effective tax rate was due primarily to lower levels of tax-exempt income.

Our accounting policies for the recognition of income taxes in the Consolidated Statements of Financial Condition and Income are included in Notes 1 and 15 to the Consolidated Financial Statements of our 2015 10-K.

FINANCIAL CONDITION

Investment Portfolio Management

Securities that we have the intent and ability to hold until maturity are classified as securities held-to-maturity and are accounted for using historical cost, adjusted for amortization of premiums and accretion of discounts. Trading securities are carried at fair value and consist of securities held in a grantor trust for our nonqualified deferred compensation plan and are not considered part of the traditional investment portfolio. All other securities are classified as securities available-for-sale and are carried at fair value with unrealized gains and losses, net of related deferred income taxes, recorded in stockholders' equity as a separate component of accumulated other comprehensive loss.

We manage our investment portfolio to maximize the return on invested funds within acceptable risk guidelines, to meet pledging and liquidity requirements, and to adjust balance sheet interest rate sensitivity to mitigate the impact of changes in interest rates on net interest income.

49

From time to time, we adjust the size and composition of our securities portfolio based on a number of factors, including expected loan growth, anticipated changes in collateralized public funds on account, the interest rate environment, and the related value of various segments of the securities markets. The following table provides a valuation summary of our investment portfolio.

Portfolio Composition

As of March 31, 2016, our securities available-for-sale portfolio totaled $1.6 billion, rising $318.9 million, or 24.4%, from December 31, 2015. The increase from December 31, 2015 reflects securities purchases of $276.3 million, consisting primarily of CMOs and MBSs, and $125.8 million in securities acquired in the NI Bancshares transaction, which were partially offset by sales of $30.6 million and maturities, calls, and prepayments of $68.2 million. For additional detail regarding sales of securities see the "Securities Gains and Losses" section below.

Approximately 98% of our securities available-for-sale portfolio is comprised of U.S. treasury securities, U.S. agency securities, CMOs, MBSs, and municipal securities. The remainder consists of eleven CDOs with a fair value of $30.8 million and miscellaneous other securities with a fair value of $3.2 million.

Investments in municipal securities comprised $328.0 million, or 20.2%, of the total securities available-for-sale portfolio at March 31, 2016. The majority consists of general obligations of local municipalities in various states. Our municipal securities portfolio has historically experienced very low default rates and provides a predictable cash flow.

⁽¹⁾  The effective duration represents the estimated percentage change in the fair value of the securities portfolio given a 100 basis point increase or decrease in interest rates. This measure is used to evaluate the portfolio's price volatility at a single point in time and is not intended to be a precise predictor of future fair values since those values will be influenced by a number of factors.

⁽²⁾  Average life is presented in years and represents the weighted-average time to receive half of all future cash flows using the dollar amount of principal paydowns, including estimated principal prepayments, as the weighting factor.

⁽³⁾  Yields on municipal securities are reflected on a tax-equivalent basis, assuming a federal income tax rate of 35%.

Effective Duration

The average life and effective duration of our securities available-for-sale portfolio of 3.66 years and 3.03%, respectively, as of March 31, 2016 were both lower than December 31, 2015. These decreases were due to the addition of shorter-duration CMOs and MBSs, which was partially offset by the replacement of matured municipal securities with longer-duration municipal securities.

Realized Gains and Losses

Net securities gains for the first quarter 2016 and 2015 were $887,000 and $512,000, respectively, on securities with carrying values of $30.6 million and $35.7 million for the same periods. No impairment charges were recognized during the first quarter of 2016 or 2015.

Unrealized Gains and Losses

Unrealized gains and losses on securities available-for-sale represent the difference between the aggregate cost and fair value of the portfolio. These amounts are presented in the Consolidated Statements of Comprehensive Income and reported as a separate component of stockholders' equity in accumulated other comprehensive loss on an after-tax basis. This balance sheet component will fluctuate as current market interest rates and conditions change and affect the aggregate fair value of the portfolio. As of March 31, 2016, net unrealized gains totaled $476,000 compared to net unrealized losses of $17.5 million as of December 31, 2015.

Net unrealized gains in the CMO portfolio totaled $6.1 million at March 31, 2016 compared to net unrealized losses of $8.0 million as of December 31, 2015. Net unrealized gains on CMOs at March 31, 2016 included unrealized losses of $2.0 million. The MBS portfolio had net unrealized gains of $3.4 million as of March 31, 2016, compared to $1.0 million as of December 31, 2015, which included unrealized losses of $114,000 and $871,000 for the same periods, respectively. CMOs and MBSs are either backed by U.S. government-owned agencies or issued by U.S. government-sponsored enterprises. We do not believe any individual unrealized loss on these securities as of March 31, 2016 represents an other-than-temporary securities impairment ("OTTI") related to credit deterioration. In addition, we do not intend to sell the CMOs and MBSs with unrealized losses within a short period of time, and we do not believe it is more likely than not that we will be required to sell them before recovery of their amortized cost basis, which may be at maturity.

51

As of March 31, 2016, net unrealized gains in the municipal securities portfolio totaled $6.5 million compared to $6.1 million as of December 31, 2015. Net unrealized gains on municipal securities include unrealized losses of $159,000 and $310,000 as of March 31, 2016 and December 31, 2015, respectively. Substantially all of these securities carry investment grade ratings, with the majority supported by the general revenues of the issuing governmental entity, and are supported by third party bond insurance or other types of credit enhancement. We do not believe the unrealized loss on any of these securities represents OTTI.

Our investments in CDOs are supported by the credit of the underlying banks and insurance companies. The net unrealized losses on these securities were $17.5 million as of March 31, 2016 and $16.8 million as of December 31, 2015. We do not believe the unrealized losses on the CDOs as of March 31, 2016 represent OTTI related to credit deterioration. In addition, we do not intend to sell the CDOs with unrealized losses within a short period of time, and we do not believe it is more likely than not that we will be required to sell them before recovery of their amortized cost basis, which may be at maturity. Our estimation of fair values for the CDOs is described in Note 14 of "Notes to the Condensed Consolidated Financial Statements," in Part I, Item 1 of this Form 10-Q.

LOAN PORTFOLIO AND CREDIT QUALITY

Portfolio Composition

Our loan portfolio is comprised of both corporate and consumer loans with corporate loans representing 83.2% of total loans at March 31, 2016. Consistent with our emphasis on relationship banking, the majority of our corporate loans are made to our core, multi-relationship customers. The customers usually maintain deposit relationships and utilize our other banking services, such as treasury or wealth management services.

To maximize loan income within an acceptable level of risk, we have certain lending policies and procedures that management reviews on a regular basis. In addition, management receives periodic reporting related to loan production, loan quality, credit concentrations, loan delinquencies, and non-performing and performing potential problem loans to monitor and mitigate potential and current risks in the portfolio.

⁽¹⁾  Amounts represent loans acquired in the NI Bancshares transaction, which was completed late in the first quarter of 2016.

Total loans increased by 9.2% from December 31, 2015. Excluding loans acquired in the NI Bancshares transaction of $395.8 million, total loans grew 3.7% from December 31, 2015, driven primarily by strong sales production of the corporate and consumer lending teams. Overall, the mix of loans remained consistent with the prior period.

Growth in corporate loans reflects the strong sales performance across diversified commercial real estate categories, as well as continued expansion into select sector-based lending areas such as healthcare, structured finance, and equipment financing. The rise in consumer loans reflects the continued expansion of online installment lending channels, as well as the addition of shorter-duration, floating rate home equity loans and 1-4 family mortgages.

Commercial, Industrial, and Agricultural Loans

Commercial, industrial, and agricultural loans represent 39.1% of total loans and totaled $3.1 billion at March 31, 2016, an increase of 5.0% from December 31, 2015. Loans acquired in the NI Bancshares transaction during the first quarter of 2016 contributed $78.7 million, or 2.7%. Our commercial and industrial loans are a diverse group of loans generally located in the Chicago metropolitan area with purposes that range from supporting seasonal working capital needs to term financing of equipment. Our commercial and industrial portfolio does not have significant direct exposure to the oil and gas industry. Most commercial and industrial loans are secured by the assets being financed or other business assets, such as accounts receivable or inventory. The underlying collateral securing commercial and industrial loans may fluctuate in value due to the success of the business or economic conditions. For loans secured by accounts receivable, the availability of funds for repayment and economic conditions may impact the cash flow of the borrower. Accordingly, the underwriting for these loans is based primarily on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower and may incorporate a personal guarantee.

Agricultural loans are generally provided to meet seasonal production, equipment, and farm real estate borrowing needs of individual and corporate crop and livestock producers. Seasonal crop production loans are repaid by the liquidation of the financed crop that is typically covered by crop insurance. Equipment and real estate term loans are repaid through cash flows of the farming operation. Risks uniquely inherent in agricultural loans relate to weather conditions, agricultural product pricing, and loss of crops or livestock due to disease or other factors. Therefore, as part of the underwriting process, the Company examines projected future cash flows, financial statement stability, and the value of the underlying collateral.

Commercial Real Estate Loans

Commercial real estate loans are subject to underwriting standards and processes similar to commercial and industrial loans. The repayment of commercial real estate loans depends on the successful operation of the property securing the loan or the business conducted on the property securing the loan. This category of loans may be more adversely affected by conditions in the real estate market. In addition, many commercial real estate loans do not fully amortize over the term of the loan, but have balloon payments due at maturity. The borrower's ability to make a balloon payment may depend on the availability of long-term financing or their ability to complete a timely sale of the underlying property. Management monitors and evaluates commercial real estate loans based on cash flow, collateral, geography, and risk rating criteria. The mix of properties securing the loans in our commercial real estate portfolio is balanced between owner-occupied and investor categories and are diverse in terms of type and geographic location, generally within the Company's markets.

Construction loans are generally based on estimates of costs and values associated with the completed projects and are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analyses of absorption and lease rates, and financial analyses of the developers and property owners. Sources of repayment may be permanent financing from long-term lenders, sales of developed property, or an interim loan commitment until permanent financing is obtained. Generally, construction loans have a higher risk profile than other real estate loans since repayment is impacted by real estate values, interest rate changes, governmental regulation of real property, demand and supply of alternative real estate, the availability of long-term financing, and changes in general economic conditions.

Commercial real estate loans represent 44.1% of total loans and totaled $3.4 billion at March 31, 2016, increasing by $377.7 million, or 12.3%, from December 31, 2015. Loans acquired in the NI Bancshares transaction during the first quarter of 2016 contributed $235.7 million, or 7.7%. Owner-occupied commercial real estate loans represent approximately 40% of total commercial real estate loans, excluding multi-family and construction loans, at March 31, 2016 and December 31, 2015.

Consumer Loans

Consumer loans represent 16.4% of total loans, and totaled $1.3 billion at March 31, 2016, an increase of 12.3% from December 31, 2015. Loans acquired in the NI Bancshares transaction during the first quarter of 2016 contributed $81.5 million, or 7.1%. Consumer loans are centrally underwritten using a credit scoring model developed by the Fair Isaac Corporation ("FICO"), which employs a risk-based system to determine the probability a borrower may default. Underwriting standards for home equity loans are heavily influenced by statutory requirements, which include loan-to-value and affordability ratios, risk-based pricing strategies, and documentation requirements. The home equity category consists mainly of revolving lines of credit secured by junior liens on owner-occupied real estate. Loan-to-value ratios on home equity loans and 1-4 family mortgages are based on the current appraised value of the collateral. Repayment for these loans is dependent on the borrower's continued financial stability, and is more likely to be impacted by adverse personal circumstances.

⁽¹⁾  Due to the impact of protection provided by the loss share agreements with the FDIC that substantially mitigate the risk of loss, covered loans and covered OREO are separated in this table. Past due covered loans in the table above are determined by borrower performance compared to contractual terms, but are considered accruing loans since they continue to perform in accordance with our expectations of cash flows. For a discussion of covered loans, see Note 1 and Note 6 of "Notes to the Condensed Consolidated Financial Statements" in Part I, Item 1 of this Form 10-Q.

Excluding covered loans and OREO, total non-performing assets represented 0.88% of total loans and OREO at March 31, 2016, consistent with 0.86% at December 31, 2015 and down from 1.20% at March 31, 2015.

Loans 30-89 days past due to total loans, excluding covered loans, was 0.38% at March 31, 2016 compared to 0.23% at December 31, 2015 and 0.28% at March 31, 2015, respectively. The increase in loans 30-89 days past due compared to the fourth quarter of 2015 was driven primarily by normal fluctuations and loans acquired in the NI Bancshares transaction that are currently in the process of renewal.

56

TDRs

Loan modifications may be performed at the request of an individual borrower and may include reductions in interest rates, changes in payments, and extensions of maturity dates. We occasionally restructure loans at other than market rates or terms to enable the borrower to work through financial difficulties for a period of time, and these restructures remain classified as TDRs for the remaining term of the loans.

TDRs totaled $5.0 million at March 31, 2016, consistent with December 31, 2015. Accruing TDRs were $2.7 million at March 31, 2016 and December 31, 2015. TDRs are reported as non-accrual if they are not performing in accordance with their modified terms or they have not yet exhibited sufficient performance under their modified terms.

57

Performing Potential Problem Loans

Performing potential problem loans consist of special mention loans and substandard loans, excluding TDRs. These loans are performing in accordance with their contractual terms, but we have concerns about the ability of the borrower to continue to comply with loan terms due to the borrower's operating or financial difficulties.

Performing potential problem loans to corporate loans	3.37		%	1.77		%	5.14		%	2.38		%	2.03		%	4.41		%

⁽¹⁾  Loans categorized as special mention exhibit potential weaknesses that require the close attention of management since these potential weaknesses may result in the deterioration of repayment prospects in the future.

⁽²⁾  Loans categorized as substandard exhibit well-defined weaknesses that may jeopardize the liquidation of the debt. These loans continue to accrue interest because they are well-secured and collection of principal and interest is expected within a reasonable time.

⁽³⁾  Total performing potential problem loans excludes accruing TDRs of $854,000 as of March 31, 2016 and $862,000 as of December 31, 2015.

Performing potential problem loans were 5.1% of corporate loans at March 31, 2016 compared to 4.4% at December 31, 2015. Compared to December 31, 2015, these levels reflect the reclassification of certain commercial and industrial and agricultural loans to special mention. The reclassification of these commercial and industrial loans resulted primarily from two highly leveraged companies that have exit strategies for which we anticipate no losses. Weakening grain commodity pricing drove the reclassification of certain agricultural loans for which management has specific monitoring plans.

OREO

OREO consists of properties acquired as the result of borrower defaults on loans. OREO was $29.6 million at March 31, 2016, increasing $1.9 million, or 6.7%, from December 31, 2015.

Allowance for Credit Losses

Methodology for the Allowance for Credit Losses

The allowance for credit losses is comprised of the allowance for loan losses and the reserve for unfunded commitments and is maintained by management at a level believed adequate to absorb estimated losses inherent in the existing loan portfolio. Determination of the allowance for credit losses is inherently subjective since it requires significant estimates and management judgment, including the amounts and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans, and consideration of current economic trends.

Acquired loans are recorded at fair value, which incorporates credit risk, at the date of acquisition. No allowance for credit losses is recorded on the acquisition date. As the acquisition adjustment is accreted into income over future periods, an allowance for credit losses is established as necessary to reflect credit deterioration. In addition, certain acquired loans that have renewed subsequent to their respective acquisition dates are no longer classified as acquired loans. Instead, they are included with our loan population that is allocated an allowance in accordance with our allowance for loan losses methodology.

While management utilizes its best judgment and information available, the ultimate adequacy of the allowance for credit losses depends on a variety of factors beyond the Company's control, including the performance of its loan portfolio, the economy, changes in interest rates and property values, and the interpretation of loan risk ratings by regulatory authorities. Management believes that the allowance for credit losses is an appropriate estimate of credit losses inherent in the loan portfolio as of March 31, 2016.

The accounting policy for the allowance for credit losses is discussed in Note 1 of "Notes to the Condensed Consolidated Financial Statements" in Part I, Item 1 of this Form 10-Q.

59

An allowance for credit losses is established on loans originated by the Bank, acquired loans, and covered loans. Additional discussion regarding acquired and covered loans can be found in Note 6 of "Notes to the Condensed Consolidated Financial Statements" in Part I, Item 1 of this Form 10-Q. The following table provides additional details related to acquired loans, the allowance for credit losses as related to acquired loans and the remaining acquisition adjustment associated with acquired loans as of March 31, 2016 and December 31, 2015.

⁽¹⁾  These amounts and ratios relate to the loans acquired in completed acquisitions.

⁽²⁾  The remaining acquisition adjustment consists of $13.4 million and $18.2 million relating to purchased credit impaired ("PCI") and non-purchased credit impaired ("Non-PCI") loans, respectively, as of March 31, 2016, and $8.5 million and $9.2 million relating to PCI and Non-PCI loans, respectively, as of December 31, 2015.

Excluding acquired loans, the allowance for credit losses to total loans was 1.11% as of March 31, 2016. The acquisition adjustment increased by $13.9 million during the first quarter of 2016, driven primarily by the NI Bancshares transaction. This was partially offset by acquired loan accretion which is included in interest income, resulting in a remaining acquisition adjustment as a percent of acquired loans of 3.48%. Acquired loans that are renewed at market terms are no longer classified as acquired loans. These loans totaled $63.7 million as of March 31, 2016 and are included in loans, excluding acquired loans, in the table above and allocated an allowance in accordance with our allowance for loan losses methodology. In addition, there is an allowance for credit losses of $1.7 million on loans acquired.

Activity in the Allowance for Credit Losses

The allowance for credit losses was $78.4 million as of March 31, 2016, an increase of $3.5 million from December 31, 2015, and represents 1.00% of total loans compared to 1.05% at December 31, 2015.

The provision for loan losses was $7.6 million for the quarter ended March 31, 2016, compared to $4.5 million and $6.6 million for the quarters ended December 31, 2015 and March 31, 2015, respectively. The increase compared to both prior periods resulted primarily from growth in the loan portfolio during the first quarter of 2016.

Total net loan charge-offs to average loans for the first quarter of 2016 was 22 basis points, or $4.1 million, consistent with 19 basis points for the fourth quarter of 2015 and decreasing from 50 basis points for the first quarter of 2015.

FUNDING AND LIQUIDITY MANAGEMENT

The following table provides a comparison of average funding sources. We believe that average balances, rather than period-end balances, are more meaningful in analyzing funding sources because of the normal fluctuations that may occur on a daily or monthly basis within funding categories.

Total average funding sources for the first quarter of 2016 increased by 2.4% compared to the fourth quarter of 2015 and 6.5% compared to the first quarter of 2015. The addition of $262.5 million of FHLB advances during the first quarter of 2016 contributed to the increase in average borrowed funds compared to both prior periods presented. The rise in average core deposits compared to the fourth quarter of 2015 resulted primarily from $443.1 million in core deposits assumed in the NI Bancshares transaction, which contributed $110.0 million to average core deposits as the transaction was completed late in the first quarter of 2016. This increase more than offset the normal seasonal decline in commercial deposits. Compared to the first quarter of 2015, the rise in average core deposits was driven by growth, the NI Bancshares transaction, and the full quarter impact of deposits assumed in the December of 2015 Peoples acquisition.

On April 1, 2016, $38.5 million in subordinated notes matured and were repaid by the Company. In November of 2016 $114.9 million of senior notes will mature.

Average borrowed funds totaled $303.2 million for the first quarter of 2016 increasing by $175.7 million compared to the same period in 2015. This increase was due primarily to the addition of $262.5 million of FHLB advances during the first quarter of 2016. The weighted-average rate on FHLB advances for the first quarter of 2016 was impacted by the hedging of borrowed funds using interest rate swaps through which the Company receives variable amounts and pays fixed amounts. These interest rate swaps have a weighted-average interest rate of 2.13% as of March 31, 2016. For a detailed discussion of interest rate swaps, see Note 12 of "Notes to the Condensed Consolidated Financial Statements" in Part I, Item 1 of this Form 10-Q.

Securities sold under agreements to repurchase generally mature within 1 to 90 days from the transaction date.

MANAGEMENT OF CAPITAL

Capital Measurements

A strong capital structure is required under applicable banking regulations and is crucial in maintaining investor confidence, accessing capital markets, and enabling us to take advantage of future growth opportunities. Our capital policy requires that the Company and the Bank maintain capital ratios in excess of the minimum regulatory guidelines. It serves as an internal discipline in analyzing business risks and internal growth opportunities and sets targeted levels of return on equity. Under regulatory capital adequacy guidelines, the Company and the Bank are subject to various capital requirements set and administered by the federal banking agencies. On January 1, 2015, the Company and the Bank became subject to the Basel III Capital rules, a new comprehensive capital framework for U.S. banking organizations published by the Federal Reserve. These rules are discussed in the "Supervision and Regulation" section in Item 1, "Business" in the Company's 2015 10-K.

The following table presents our consolidated measures of capital as of the dates presented and the capital guidelines established by the Federal Reserve for the Bank to be categorized as "well-capitalized." We manage our capital ratios for both the Company and the Bank to consistently maintain these measurements in excess of the Federal Reserve's minimum levels to be considered "well-capitalized," which is the highest capital category established. All regulatory mandated ratios for characterization as "well-capitalized" were exceeded as of March 31, 2016 and December 31, 2015.

The tangible common equity ratios presented in the table below are capital adequacy metrics used and relied on by investors and industry analysts; however, they are non-GAAP financial measures. These non-GAAP measures are valuable indicators of a financial institution's capital strength since they eliminate intangible assets from stockholders' equity and retain the effect of accumulated other comprehensive loss in stockholders' equity. Reconciliations of the components of those ratios to GAAP are also presented in the table below.

⁽¹⁾  Ratios are not subject to formal Federal Reserve regulatory guidance.

⁽²⁾  In management's view, Tier 1 common capital and TCE measures are meaningful to the Company, as well as analysts and investors, in assessing the Company's use of equity and in facilitating comparisons with competitors.

The Company's regulatory capital ratios related to end-of-period risk-weighted assets decreased due to organic loan growth and the NI Bancshares acquisition completed late in the first quarter of 2016.

The Board of Directors reviews the Company's capital plan each quarter, considering the current and expected operating environment as well as an evaluation of various capital alternatives.

Dividends

The Board of Directors approved a quarterly cash dividend of $0.09 per common share during the first quarter of 2016. The dividend increased from $0.08 to $0.09 per common share during the first quarter of 2015.

ITEM 3. QUANTITATIVE AND QUALITATIVE

DISCLOSURES ABOUT MARKET RISK

Market risk is the risk of loss arising from adverse changes in the fair value of financial instruments due to changes in interest rates, exchange rates, and equity prices. Interest rate risk is our primary market risk and is the result of repricing, basis, and option risk. A description and analysis of our interest rate risk management policies is included in Part II, Item 7A, "Quantitative and Qualitative Disclosures about Market Risk," in our 2015 10-K.

We seek to achieve consistent growth in net interest income and net income while managing volatility that arises from shifts in interest rates. The Bank's Asset Liability Committee ("ALCO") oversees financial risk management by developing programs to measure and manage interest rate risks within authorized limits set by the Bank's Board of Directors. ALCO also approves the Bank's asset and liability management policies, oversees the formulation and implementation of strategies to improve balance sheet positioning and earnings, and reviews the Bank's interest rate sensitivity position. Management uses net interest income simulation modeling to analyze and capture exposure of earnings to changes in interest rates.

Net Interest Income Sensitivity

The analysis of net interest income sensitivity assesses the magnitude of changes in net interest income over a twelve-month measurement period resulting from immediate changes in interest rates using multiple rate scenarios. These scenarios include, but are not limited to, a flat or unchanged rate environment, immediate increases of 100, 200, and 300 basis points, and an immediate decrease of 100 basis points. Due to the low interest rate environment as of March 31, 2016 and December 31, 2015, management determined that an immediate decrease in interest rates greater than 100 basis points was not meaningful for this analysis.

This simulation analysis is based on expected future cash flows and repricing characteristics for balance sheet and off-balance sheet instruments and incorporates market-based assumptions regarding the effect of changing interest rates on the prepayment rates of certain assets and liabilities. In addition, this sensitivity analysis examines assets and liabilities at the beginning of the measurement period and does not assume any changes from growth or business plans over the next twelve months. Interest-earning assets and interest-bearing liabilities are assumed to re-price based on contractual terms over the twelve-month measurement period assuming an instantaneous parallel shift in interest rates in effect at the beginning of the measurement period. The simulation analysis also incorporates assumptions based on the historical behavior of deposit rates in relation to interest rates. Because these assumptions are inherently uncertain, the simulation analysis cannot definitively measure net interest income or predict the impact of the fluctuation in interest rates on net interest income, but does provide an indication of the Company's sensitivity to changes in interest rates. Actual results may differ from simulated results due to timing, magnitude, and frequency of interest rate changes as well as changes in market conditions and management strategies.

Our balance sheet is asset sensitive based on repricing and maturity characteristics and simulation analysis assumptions. The Bank's current simulation analysis indicates we would benefit from rising interest rates. Interest-earning assets consist of short and long-term products. Excluding non-accrual loans, 44% of the loan portfolio consisted of fixed rate loans and 56% were floating rate loans as of March 31, 2016, compared to 54% and 46%, respectively, as of December 31, 2015.

As of March 31, 2016, investments, consisting of securities and interest-bearing deposits in other banks, are more heavily weighted toward fixed rate securities at 91% of the total compared to 9% for floating rate interest-bearing deposits in other banks. This compares to investments comprising 84% of fixed rate securities and 16% of floating rate interest-bearing deposits in other banks as of December 31, 2015. Fixed rate loans are most sensitive to the 3-5 year portion of the yield curve and the Bank limits its loans with maturities that extend beyond 5 years. The majority of floating rate loans are indexed to the short-term Prime or LIBOR rates. The amount of floating rate loans with active interest rate floors was $416.2 million, or 10%, of the floating rate loan portfolio as of March 31, 2016, compared to $374.5 million, or 10%, of the floating rate loan portfolio as of December 31, 2015. On the liability side of the balance sheet, 85% and 86% of deposits as of March 31, 2016 and December 31, 2015, respectively, are demand deposits or interest-bearing core deposits, which either do not pay interest or the interest rates are expected to rise at a slower pace than short-term interest rates.

Percent change	14.8		%	8.9		%	6.2		%	(5.9		)%

The sensitivity of estimated net interest income to an instantaneous parallel shift in interest rates is reflected as both dollar and percentage changes. This table illustrates that an instantaneous 200 basis point rise in interest rates as of March 31, 2016 would increase net interest income by $28.9 million, or 8.4%, over the next twelve months compared to no change in interest rates. This same measure was $28.0 million, or 8.9%, as of December 31, 2015.

Overall, interest rate risk volatility as of March 31, 2016 decreased slightly compared to December 31, 2015, driven primarily by the NI Bancshares acquisition which added term securities and fixed rate loans. This decline was partly offset by organic growth in floating rate loans and term securities, funded by short-term FHLB advances and organic growth in core deposits, which are less rate sensitive. While net interest income is projected to decline in a decreasing interest rate environment, we believe the risk of a significant and sustained decrease in interest rates is minimal.

ITEM 4. CONTROLS AND PROCEDURES

At the end of the period covered by this report, (the "Evaluation Date"), the Company carried out an evaluation, under the supervision and with the participation of the Company's management, including the Company's President and Chief Executive Officer and its Executive Vice President and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Based on that evaluation, the President and Chief Executive Officer and Executive Vice President and Chief Financial Officer concluded that as of the Evaluation Date, the Company's disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission rules and forms. There were no changes in the Company's internal control over financial reporting during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In the ordinary course of business, there were certain legal proceedings pending against the Company and its subsidiaries at March 31, 2016. While the outcome of any legal proceeding is inherently uncertain, based on information currently available, the Company's management does not expect any liabilities arising from pending legal matters to have a material adverse effect on the Company's financial condition, results of operations, or cash flows.

ITEM 1A. RISK FACTORS

The Company provided a discussion of certain risks and uncertainties faced by the Company in its Annual Report on Form 10-K for 2015. However, these factors may not be the only risks or uncertainties the Company faces.

Exhibit 10.1

[Date]

[Name]

[Address]

RE: Award Letter Agreement dated [Date]; Restricted Stock Award [Number];

Grant of Restricted Stock (the “Award Agreement”)

Dear [Name]:

On behalf of First Midwest Bancorp, Inc. (the “Company”), I am pleased to advise you that on [Date] (the “Date of Grant”), and pursuant to the First Midwest Bancorp, Inc. Omnibus Stock and Incentive Plan, as amended (the “Omnibus Plan”), the Compensation Committee (the “Compensation Committee”) of the Board of Directors of the Company approved a grant to you of a restricted stock award (the “Award”) as set forth in this Award Agreement. The Award is also subject to the terms and conditions of the Omnibus Plan, as currently in effect or as may be amended hereafter, which are incorporated herein by reference.

(1) Award

(a) The Company hereby grants to you an Award of an opportunity to earn [Number of Shares] shares of the Company’s common stock, $0.01 par value per share (“Common Stock”), subject to the restrictions and other conditions set forth herein and in the Omnibus Plan. Such shares are referred to in this Award Agreement as the “Restricted Shares.” Restricted Shares may not be sold, transferred, pledged, gifted, assigned or otherwise alienated or hypothecated, subject to paragraphs (2), (3), (4) and (5). Within a reasonable time after the date of this Award, the Company shall instruct its stock transfer agent to establish a book entry account representing the Restricted Shares in your name effective as of the Date of Grant, provided that the Company shall retain control of such account until the Restricted Shares have become vested in accordance with the Award.

(b) As promptly as practical after the date on which a portion or all of the Restricted Shares vest under this Award Agreement, and after receipt of any required tax withholding under paragraph 8, the Company shall instruct the stock transfer agent to transfer the number of vested Restricted Shares (less any shares withheld in satisfaction of tax withholding obligations under paragraph 8, if any) to an unrestricted account over which only you (or, in the case of your death, your designated beneficiary or authorized representative) have control.

(2) Restrictions; Vesting

Except as otherwise provided in paragraphs (3) and (4), the Restricted Shares shall vest and become transferable only if you continue in the employment of the Company or any of its subsidiaries through the applicable vesting dates. The Restricted Shares will vest and become transferable as follows: (a) 50% will vest on [Vest Date 1]; and (b) the remaining 50% of the Award will vest on [Vest Date 2].

(3) Termination of Employment

This Letter Agreement constitutes part of a prospectus covering securities that have been registered under the Securities Act of 1933, as amended.

If your employment with the Company or any of its subsidiaries terminates due to your Retirement at or after your Normal Retirement Date, a Qualifying Termination (as defined below), a Disability or your death prior to the full vesting of the Restricted Shares, (i) the Period of Restriction will automatically terminate and all restrictions on any unvested Restricted Shares will lapse, (ii) all unvested Restricted Shares will become immediately vested and freely transferable in full, subject to withholding for taxes under paragraph (8)) and the provisions of paragraph 1(b) shall apply, and (iii) all dividends credited to you pursuant to paragraph (7) will become payable to you. If your employment with the Company or any of its subsidiaries terminates for any other reason prior to the full vesting of the Restricted Shares, all unvested Restricted Shares and all dividends credited to you pursuant to paragraph (7) shall be immediately forfeited, and all of your rights hereunder and to an Award shall terminate.

For purposes of this Award Agreement, a “Qualifying Termination” shall mean your employment is terminated without Cause (as defined below) or you resign your employment for Good Reason (as defined below) upon a Change of Control or within 24 months after a Change of Control.

If you are a party to an employment agreement with the Company or any subsidiary or affiliate of the Company (the “Employment Agreement”), “Cause” and “Good Reason” shall have the meanings ascribed to such terms in your Employment Agreement. If you do not have an employment agreement with the Company or any subsidiary or affiliate of the Company:

(a)“Cause” shall have the meaning ascribed to it in the Omnibus Plan.

(b) “Good Reason” shall mean the occurrence of any event, other than in connection with termination of your employment by the Company, which results in (A) a material diminution of your principal duties or responsibilities from those in effect immediately prior to the Change in Control, including, without limitation, a significant change in the nature or scope of your principal duties or responsibilities, such that your duties or responsibilities are inconsistent with those immediately prior to the Change in Control, and commonly (in the banking industry) considered to be of lesser responsibility, or (B) a material diminution of your compensation from that immediately prior to the Change in Control, or (C) you being required to be based at an office or location which is more than 35 miles from your office or location immediately prior to the Change in Control. Notwithstanding the foregoing, in order for your resignation for Good Reason to occur, (x) you must provide written notice of the Good Reason event to the Company or its subsidiary within 90 days after the initial existence of such event; (y) the Company or its subsidiary must not have cured such condition within 30 days of receipt of your written notice or the Company or its subsidiary must have stated unequivocally in writing that it does not intend to attempt to cure such condition; and (z) you must resign from employment at the end of the period within which the Company or a subsidiary was entitled to remedy the condition constituting Good Reason but failed to do so.

For purposes of this Award Agreement, the determination of whether a termination of your employment is for a “Disability”, for “Cause” or for “Good Reason” shall be determined in accordance with the Omnibus Plan and this Award Agreement, unless you are a party to an Employment Agreement, in which case such determination under your Employment Agreement will control.

(4) Effect of Change in Control

A Change in Control shall not, by itself, result in acceleration of vesting of the Restricted Shares, except as provided in this paragraph (4).

Upon a Change in Control prior to the full vesting of the Restricted Shares, unless another award meeting the requirements of this paragraph (4) (a “Substitute Award”) is provided to you to replace this Award (the “Original Award”), the Period of Restriction will automatically terminate and all restrictions on any unvested Restricted Shares will lapse, all unvested Restricted Shares will become immediately vested and freely transferable in full (subject to withholding for taxes under paragraph (8)) and the provisions of paragraph 1(b) shall apply, and all dividends credited to you pursuant to paragraph (7) will become payable to you.

An award shall meet the requirements of this paragraph (4), and thereby qualify as a Substitute Award, if the following conditions are met:

(a) The award has a value at least equal to the value of the Original Award;

(b) The award relates to publicly-traded equity securities of the Company or its successor following the Change in Control or another entity that is affiliated with the Company or its successor following the Change in Control; and

(c) The other terms and conditions of the award are not less favorable to you than the terms and conditions of the Original Award, including the provisions of paragraph (3) relating to vesting in the event of a Qualifying Termination (except that in the event of a subsequent Change in Control of the Company or its successor, the Substitute Award shall be fully vested and freely transferable upon such subsequent Change in Control).

Without limiting the generality of the foregoing, a Substitute Award may take the form of a continuation of the Original Award if the requirements of the preceding sentence are satisfied. The determination of whether the conditions of this paragraph (4) are satisfied shall be made by the Committee, as constituted immediately before the Change in Control, in its sole discretion.

(5) Non-Transferability

Subject to the terms of this Award Agreement, this Award is personal to you and, until vested and transferable hereunder, may not be sold, transferred, pledged, gifted, assigned or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution.

(6) Securities Law Restrictions

You understand and acknowledge that applicable securities laws, rules and regulations govern and may restrict your right to offer, sell or otherwise dispose of any vested Common Stock received under the Award.

Executive Officers of the Company subject to the two (2) day reporting rules of Section 16(a) and short-swing profit recovery rules of Section 16(b) of the Securities Exchange Act of 1934 should consult the Company’s Corporate Secretary prior to selling any such vested Common Stock.

Additional information regarding these laws, rules and regulations can be found in the Omnibus Plan’s “Summary Description” and the document entitled “General Information Regarding Restricted Share Grants”.

(7)Stockholder Rights

Upon the effective date of the book entry of your Restricted Shares pursuant to paragraph (1), you shall have the right to vote the Restricted Shares represented by the Award.

In the event the Company declares the payment of a cash dividend, a stock dividend (as defined in Section 305 of the Internal Revenue Code of 1986, as amended (the “IRC”)) or a stock split on the Common Stock with a record date occurring during the Award’s Period of Restriction, you shall be credited with either a dollar amount equal to the amount of the cash dividends paid or the number of shares equal to the stock dividend or stock split with respect to the Restricted Shares held by you as of the close of business on the record date for such dividend or stock split, as the case may be. The Company will hold all such cash dividends until the Period of Restriction terminates, and such dividends shall become payable to you on each vesting date of the Award with respect to only the Restricted Shares that vest on such date. All shares issued to you in connection with a stock dividend or stock split shall be subject to the same restrictions on transferability as the Restricted Shares, and the Period of Restriction shall terminate with respect to such shares at the same time and in the same proportion that the Restricted Shares vest. Subject to the provisions of paragraphs (3) and (4), in the event your employment with the Company terminates prior to full vesting of the Award, cash dividends and shares issued in connection with a stock dividend or stock split held by the Company and credited to you that have not been paid or vested will be forfeited.

(8)Withholding

You shall pay all applicable federal, state and local income and employment taxes (including taxes of any foreign jurisdiction) that the Company is required to withhold at any time with respect to the Restricted Shares, which will generally occur (a) as the Restricted Shares (including shares issued in connection with a stock dividend or stock split) vest, (b) when cash dividends are actually paid to you at the time any Restricted Shares vest, or (c) as of the Date of Grant if you file an election under Section 83(b) of the IRC. Withholding with respect to cash dividends will be paid through withholding from your next normal payroll check. Payment of withholding upon vesting of any Restricted Shares will be accomplished through withholding by the Company of Restricted Shares then vesting under this Award with a value equal to the minimum statutory withholding amount, or such greater amount as the Compensation Committee may authorize, provided the withholding of such greater amount does not result in adverse accounting consequences for the Company. Shares withheld as payment of required withholding shall be valued at Fair Market Value on the date such withholding obligation arises. Payment of withholding as a result of a Section 83(b) election must be made by you to the Company in cash or by delivering fully-vested then-owned shares of Common Stock with a Fair Market Value equal to the required withholding amount.

(9) Tax Consequences

Information regarding federal tax consequences of the Award can be found in the Omnibus Plan's “Summary Description”, and the document entitled “General Information Regarding Restricted

Share Grants”. You are strongly encouraged to contact your tax advisor regarding such tax consequences as they relate to you.

(10) Employment; Successors

Nothing herein confers any right or obligation on you to continue in the employment of the Company or any subsidiary or shall affect in any way your right or the right of the Company or any subsidiary, as the case may be, to terminate your employment at any time, subject to the terms of any employment agreement to which the Company and you may be parties. Nothing herein shall create any right for you to receive, or any obligation on the part of the Company to grant to you, any future Awards under the Omnibus Plan. This Award Agreement shall be binding upon, and inure to the benefit of, any successor or assignee of the Company.

(11) Conformity with the Omnibus Plan

(a) The Award is intended to conform in all respects with the Omnibus Plan. Inconsistencies between the Omnibus Plan and this Award Agreement shall be resolved in accordance with the provisions of this Award Agreement. By executing and returning the enclosed Confirmation of Acceptance of this Award Agreement, you agree to be bound by all the terms hereof and of the Omnibus Plan. All capitalized terms used but not otherwise defined in this Award Agreement shall have the same definitions stated in the Omnibus Plan.

(b) Any action taken or decision made by the Compensation Committee arising out of or in connection with the construction, administration, interpretation or effect of this Award Agreement or the Omnibus Plan shall lie within the Compensation Committee’s sole and absolute discretion, and shall be final, conclusive and binding on you and all persons claiming under or through you. This Award Agreement shall be binding upon your heirs, executors, administrators and successors.

(c) Except as otherwise provided in this Award Agreement, this Award Agreement shall be construed and interpreted in accordance with the laws of the State of Delaware without reference to any choice of law rules thereof (whether of the State of Delaware or any other jurisdiction) that would cause the application of any laws of any jurisdiction other than the State of Delaware.

(12)Confidentiality and Restrictive Covenants

You acknowledge and agree that the Award has been conditioned upon your compliance with (and no Restricted Shares shall vest or become transferable by you hereunder unless you have complied and continue to comply with) the provisions of this paragraph (12). In consideration of your eligibility to receive the Award contemplated by this Award Agreement and any cash award under the Company’s Short Term Incentive Compensation (“STIC”) Plan and by executing (in writing or by electronic means) the Confirmation of Acceptance endorsement of this Award Agreement, you further acknowledge and agree as follows:

(i) In the event that you breach any of the covenants or agreements set forth in this paragraph (12) and/or any Employment Agreement and/or CRCA, you shall immediately forfeit all rights to the Award and the Restricted Shares and all unearned, unvested or unexercised awards under the Omnibus Plan and the STIC Plan; and

(j) The validity, interpretation, construction and performance of this paragraph (12) shall be governed by the laws of the State of Illinois without giving effect to the conflict of law principles thereof. The exclusive venue for any litigation between you and the Company or any of its subsidiaries or affiliates for any dispute arising out of or relating to this Agreement shall be the state court located in Cook County, Illinois, or the federal district court located in Chicago, Illinois, and you hereby irrevocably consent to any such court’s exercise of personal jurisdiction over you for such purpose; and

(k) The restrictions set forth in this paragraph (12) are reasonable and necessary for the protection of each member of the Affiliated Group’s legitimate business interests, and do not impose any undue economic hardship on you or otherwise preclude you from gainful employment.

(13)Regulatory Requirements

You also acknowledge and agree anything in this Award to the contrary notwithstanding, it is intended that, to the extent required, this Award and your receipt of Restricted Shares or any other amounts hereunder comply with the requirements of any legislative or regulatory limitations or requirements which are or may become applicable to the Company and this Award or payments made hereunder, including the Sarbanes-Oxley Act of 2002 and the Dodd-Frank Wall Street Reform and Consumer Protection Act, and any rules or regulations issued thereunder (collectively, the “Regulatory Requirements”), which limitations or requirements may include, but are not limited to, provisions limiting, delaying or deferring the issuance of the Restricted Shares or payments hereunder (including, but not limited to, under Section 409A of the IRC), requiring that the Company may recover (claw-back) incentive compensation in certain circumstances and precluding incentive arrangements, such as this Award, that encourage unnecessary or excessive risks that threaten the value of the Company, in each case within the meaning of the Regulatory Requirements, and only to the extent applicable to the Company and this Award. The application of this paragraph is intended to, and shall be interpreted, administered and construed to, cause this Award to comply with the Regulatory Requirements and, to the maximum extent consistent with this paragraph and the Regulatory Requirements, to permit the operation of this Award in accordance with the terms and conditions hereof before giving effect to the provisions of this paragraph or the Regulatory Requirements.

RE: Award Letter Agreement dated [Date]; Restricted Stock Unit Award [Number];

Grant of Restricted Stock Units (the “Award Agreement”)

Dear [Name]:

On behalf of First Midwest Bancorp, Inc. (the “Company”), I am pleased to advise you that on [Date] (the “Date of Grant”), and pursuant to the First Midwest Bancorp, Inc. Omnibus Stock and Incentive Plan, as amended (the “Omnibus Plan”), the Compensation Committee (the “Compensation Committee”) of the Board of Directors of the Company approved a grant to you of an award of restricted stock units (the “Award”) as set forth in this Award Agreement. The Award is also subject to the terms and conditions of the Omnibus Plan, as currently in effect or as may be amended hereafter, which are incorporated herein by reference. The Award provides you with the opportunity to earn shares of the Company's common stock, $0.01 par value per share ("Common Stock") upon vesting of the restricted stock units.

(1) Award

The Company hereby grants to you an Award of [Number of Shares] restricted stock units, each of which represents an opportunity to earn one share of Common Stock on the vesting date (less any shares withheld in satisfaction of tax withholding obligations under paragraph 8, if any), subject to the vesting provisions of paragraph 2 and the other provisions of this Award Agreement and the Omnibus Plan. Such restricted stock units contemplated by the Award are referred to in this Award Agreement as the “Restricted Units.” Restricted Units may not be sold, transferred, pledged, gifted, assigned or otherwise alienated or hypothecated, subject to paragraphs (2), (3), (4) and (5). Within a reasonable time after the date of this Award, the Company shall establish an internal book entry account representing the Restricted Units effective as of the Date of Grant, provided that the Company shall retain control of such account until the Restricted Units have become vested in accordance with the Award.

(2) Restrictions; Vesting

Except as otherwise provided in paragraphs (3) and (4) below, the Restricted Units shall vest and become payable in shares of Common Stock in accordance with paragraph (7) only if you continue in the employment of the Company or any of its subsidiaries through the applicable vesting dates. The Restricted Units will vest and become payable in shares of Common Stock as follows: (a) 50% will vest on [Vest Date 1]; and (b) the remaining 50% of the Award will vest on [Vest Date 2].

This Letter Agreement constitutes part of a prospectus covering securities that have been registered under the Securities Act of 1933, as amended.

(3) Termination of Employment

If your employment with the Company or any of its subsidiaries terminates prior to the full vesting of the Restricted Units due to your Retirement at or after your Normal Retirement Date, a Qualifying Termination (as defined below), a Disability or your death, (a) the Period of Restriction will automatically terminate and all restrictions on any unvested Restricted Units will lapse, (b) all unvested Restricted Units will become immediately vested and payable in full in shares of Common Stock in accordance with paragraph (7), subject to withholding for taxes under paragraph (8), and (c) all dividends and stock splits credited to you pursuant to paragraph (7) will become payable. If your employment with the Company or any of its subsidiaries terminates for any other reason prior to the full vesting of the Restricted Units, all unvested Restricted Units and all dividends credited to you pursuant to paragraph (7) shall be immediately forfeited, and all of your rights hereunder and to an Award shall terminate.

For purposes of this Award Agreement, a “Qualifying Termination” shall mean your employment is terminated without Cause (as defined below) or you resign your employment for Good Reason (as defined below) upon a Change of Control or within 24 months after a Change of Control.

If you are a party to an employment agreement with the Company or any subsidiary or affiliate of the Company (the “Employment Agreement”), “Cause” and “Good Reason” shall have the meanings ascribed to such terms in your Employment Agreement. If you do not have an employment agreement with the Company or any subsidiary or affiliate of the Company:

(a)“Cause” shall have the meaning ascribed to it in the Omnibus Plan.

(b) “Good Reason” shall mean the occurrence of any event, other than in connection with termination of your employment by the Company, which results in (A) a material diminution of your principal duties or responsibilities from those in effect immediately prior to the Change in Control, including, without limitation, a significant change in the nature or scope of your principal duties or responsibilities, such that your duties or responsibilities are inconsistent with those immediately prior to the Change in Control, and commonly (in the banking industry) considered to be of lesser responsibility, or (B) a material diminution of your compensation from that immediately prior to the Change in Control, or (C) you being required to be based at an office or location which is more than 35 miles from your office or location immediately prior to the Change in Control. Notwithstanding the foregoing, in order for your resignation for Good Reason to occur, (x) you must provide written notice of the Good Reason event to the Company or its subsidiary within 90 days after the initial existence of such event; (y) the Company or its subsidiary must not have cured such condition within 30 days of receipt of your written notice or the Company or its subsidiary must have stated unequivocally in writing that it does not intend to attempt to cure such condition; and (z) you must resign from employment at the end of the period within which the Company or a subsidiary was entitled to remedy the condition constituting Good Reason but failed to do so.

For purposes of this Award Agreement, the determination of whether a termination of your employment is for a “Disability”, for “Cause” or for “Good Reason” shall be determined in accordance with the Omnibus Plan and this Award Agreement, unless you are party to an Employment Agreement, in which case such determination under your Employment Agreement will control.

(4) Effect of Change in Control

A Change in Control shall not, by itself, result in acceleration of vesting of the Restricted Units, except as provided in this paragraph (4).

Upon a Change in Control prior to the full vesting of the Restricted Units, unless another award meeting the requirements of this paragraph (4) (a “Substitute Award”) is provided to you to replace this Award (the “Original Award”), all restrictions on any unvested Restricted Units will lapse and such Restricted Units shall become immediately vested and payable in full in shares of Common Stock in accordance with paragraph (7), subject to withholding under paragraph (8), and all dividends, distributions and stock splits credited to you pursuant to paragraph (7) will become payable to you.

An award shall meet the requirements of this paragraph (4), and thereby qualify as a Substitute Award, if the following conditions are met:

(a) The award has a value at least equal to the value of the Original Award;

(b) The award relates to publicly-traded equity securities of the Company or its successor following the Change in Control or another entity that is affiliated with the Company or its successor following the Change in Control; and

(c) The other terms and conditions of the award are not less favorable to you than the terms and conditions of the Original Award, including the provisions of paragraph (3) above relating to vesting in the event of a Qualifying Termination (except that in the event of a subsequent Change in Control of the Company or its successor, the Substitute Award shall be fully vested and immediately payable upon such subsequent Change in Control).

Without limiting the generality of the foregoing, a Substitute Award may take the form of a continuation of the Original Award if the requirements of the preceding sentence are satisfied. The determination of whether the conditions of this paragraph (4) are satisfied shall be made by the Committee, as constituted immediately before the Change in Control, in its sole discretion.

(5) Non-Transferability

Subject to the terms of this Award Agreement, this Award is personal to you and, until vested and transferable hereunder, may not be sold, transferred, pledged, gifted, assigned or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution.

(6) Securities Law Restrictions

You understand and acknowledge that applicable securities laws, rules and regulations govern and may restrict your right to offer, sell or otherwise dispose of any vested Common Stock received under the Award.

Executive Officers of the Company subject to the two (2) day reporting rules of Section 16(a) and short-swing profit recovery rules of Section 16(b) of the Securities Exchange Act of 1934 should consult the Company’s Corporate Secretary prior to selling any such vested Common Stock.

Additional information regarding these laws, rules and regulations can be found in the Omnibus Plan’s “Summary Description” and the document entitled “General Information Regarding Restricted Share Grants”.

(7)Stockholder Rights; Payment of Common Stock

Because this is an Award of Restricted Units and not actual shares of Common Stock, you will not have any rights of a stockholder with respect to the Restricted Units. Upon the vesting of the Restricted Units in accordance with paragraph (2), (3) or (4), as applicable, the Restricted Units will be paid to you in shares of freely transferable Common Stock, subject to applicable law.

As promptly as practical after the date on which a portion or all of the Restricted Units shall vest under this Award Agreement, and after receipt of any required tax withholding under paragraph (8), the Company shall instruct its stock transfer agent to transfer the number of vested Restricted Units, paid in the form of shares of Common Stock (less any shares withheld in satisfaction of tax withholding obligations under paragraph (8), if any), to an unrestricted account over which only you (or, in the case of your death, your designated beneficiary or authorized representative) have control. Such shares of Common Stock shall be immediately freely transferable by you.

Notwithstanding the foregoing, payment of shares of Common Stock with respect to Restricted Units that become vested upon Retirement, Qualifying Termination or Disability under paragraph (3) above may be subject to the six-month delay described in Section 18.3 of the Omnibus Plan if you are a “specified employee” at the time of your Retirement, Qualifying Termination or Disability.

In the event the Company declares the payment of a cash dividend, a stock dividend (as defined in Section 305 of the Internal Revenue Code of 1986, as amended (the “IRC”)) or a stock split on the Common Stock with a record date occurring during the Award’s Period of Restriction, you shall be credited with either a dollar amount equal to the amount of the cash dividends paid or a number of Restricted Units equal to the stock dividend or stock split as if each Restricted Unit was a share of Common Stock held by you as of the close of business on the record date for such dividend or stock split, as the case may be. The Company will hold all such cash dividends until the Period of Restriction terminates, and such dividends shall become payable to you on each vesting date of the Award with respect to only the Restricted Units that vest and become payable in Common Stock on such date. All Restricted Units credited to you in connection with a stock dividend or stock split shall be subject to the same restrictions on transferability as the Restricted Units hereunder, and the Period of Restriction shall terminate with respect to such additional Restricted Units at the same time and in the same proportion that the underlying Restricted Units vest. Subject to the provisions of paragraphs (3) and (4), in the event your employment with the Company terminates prior to full vesting of the Award, cash dividends and Restricted Units relating to a stock dividend or stock split held by the Company and credited to you that have not been paid or vested will be forfeited.

The Restricted Units are not subject to or eligible for inclusion in the First Midwest Bancorp, Inc. Dividend Reinvestment and Stock Purchase Plan. Any change in the Common Stock during the Period of Restriction shall result in an adjustment to the Award in accordance with Section 5.4 of the Omnibus Plan to prevent dilution or enlargement of rights under the Award.

(8)Withholding

You shall pay all applicable federal, state and local income and employment taxes (including taxes of any foreign jurisdiction) that the Company is required to withhold at any time with respect to the Restricted Units, which will generally occur (a) when the Restricted Units (including Restricted Units credited to you in connection with a stock split or stock dividend) vest and are paid in shares of Common Stock, and (b) when accumulated credited cash dividends are actually paid to you upon the vesting of any Restricted Units. Payment of taxes upon vesting of any Restricted Units shall be

made by withholding from any payment of Common Stock shares having a Fair Market Value on the date such withholding obligation arises equal to the minimum statutory withholding amount, or such greater amount as the Compensation Committee may authorize, provided the withholding of such greater amount does not result in adverse accounting consequences for the Company. Withholding with respect to cash dividends will be paid through withholding from your next normal payroll check.

(9) Tax Consequences

Information regarding federal tax consequences of the Award can be found in the Omnibus Plan’s “Summary Description”. You are strongly encouraged to contact your tax advisor regarding such tax consequences as they relate to you.

(10) Employment; Successors

Nothing herein confers any right or obligation on you to continue in the employment of the Company or any subsidiary or shall affect in any way your right or the right of the Company or any subsidiary, as the case may be, to terminate your employment at any time, subject to the terms of any employment agreement to which the Company and you may be parties. Nothing herein shall create any right for you to receive, or any obligation on the part of the Company to grant to you, any future Awards under the Omnibus Plan. This Award Agreement shall be binding upon, and inure to the benefit of, any successor or assignee of the Company.

Exhibit 10.3

[Date]

[Name]

[Address]

RE: Award Agreement dated [Date]; Performance Shares Award [Date]; Grant of Performance Shares

Dear [Name]:

On behalf of First Midwest Bancorp, Inc. (the “Company”), I am pleased to advise you that on [Date] (the “Date of Grant”), in recognition of your position as a key employee of the Company and your being or becoming a party to an employment agreement and/or a Confidentiality and Restrictive Covenants Agreement (“CRCA”) with the Company, the Compensation Committee (the “Compensation Committee”) and the Board of Directors of the Company approved an award of performance shares (the “Award” or the “Performance Shares”) pursuant to the First Midwest Bancorp, Inc. Omnibus Stock and Incentive Plan, as amended (the “OmnibusPlan”). The Award provides you with the opportunity to earn [Number of Shares] shares of the Company’s common stock, $0.01 par value per share (“Common Stock”).

The Award is subject to the terms and conditions of the Omnibus Plan, including any amendments thereto, which are incorporated herein by reference, and to the following provisions:

(1)Award. The Company hereby grants to you an Award of [Number of Shares] Performance Shares (the “Target Number of Performance Shares”), subject to the terms and conditions set forth herein and in Exhibits A and B hereto (this letter agreement and such Exhibits are referred to herein as the “Award Agreement”), with 50% of the Target Number of Performance Shares being subject to the relative total shareholder return performance goal set forth in Exhibit A hereto (“RTSR”) and 50% of the Target Number of Performance Shares being subject to the average annual core return on average tangible common equity performance goal set forth in Exhibit B hereto (“CRATCE”). Prior to vesting, no amount attributable to the Award may be sold, transferred, pledged, assigned or otherwise alienated or hypothecated. This Award is intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code and, accordingly, is a Performance Shares award under Section 10 of the Omnibus Plan. You may earn Performance Shares only if one or both of the performance goals are achieved at a “Threshold” level of performance or greater.

Within a reasonable time after the date of this Award, the Company shall establish in its internal records a book entry account representing the Target Number of Performance Shares

effective as of the Date of Grant, provided that the Company shall retain control of such account until the Performance Shares have become earned and vested in accordance with this Award Agreement.

(2)Earning Performance Shares; Vesting. Except as otherwise provided in Paragraph (3) below relating to termination of employment in certain circumstances and Paragraph (4) below relating to the effect of a Change in Control:

(a)Earned Performance Shares; Maximum Number of Performance Shares. The actual number of Performance Shares, if any, which are earned under this Award (the “Earned Performance Shares”) shall be determined by the Compensation Committee in accordance with this Award Agreement, including Exhibits A and B hereto. For purposes of this Award, the “Maximum Number of Performance Shares” shall be equal to two times the Target Number of Performance Shares set forth in Paragraph (1) above. In no event, however, will the number of Earned Performance Shares as determined by the Compensation Committee exceed the Maximum Number of Performance Shares.

(b)Performance Period. The performance period applicable to the Award shall be the three-year period commencing [Start Date] and ending [End Date] (the “Performance Period”).

(c)Certification of Achievement of Performance Goals. Following the end of the Performance Period, the Compensation Committee will certify whether either or both of the performance goals described in Exhibits A and B have been achieved and, if so, the number of Earned Performance Shares. The Compensation Committee’s certification and determination of achievement of such performance goals and the number of Earned Performance Shares shall be made in accordance with this Award Agreement, including Exhibits A and B hereto.

(d)Vesting of Earned Performance Shares. Upon the vesting of the Earned Performance Shares in accordance with this Award Agreement, the Earned Performance Shares will be paid to you in shares of Common Stock. Each Earned Performance Share will represent the right to receive one share of Common Stock on the applicable vesting date (less any shares withheld in satisfaction of tax withholding obligations under paragraph (8), if any). Except to the extent provided in paragraphs (3) and (4) below, Earned Performance Shares will vest and become payable in shares of Common Stock (which shall be freely transferable) in equal annual installments on the 15th day of [Vest Date 1], [Vest Date 2] and [Vest Date 3], if you are continuously employed by the Company or any of its subsidiaries through such dates.

Within a reasonable amount of time after the date that the Earned Performance Shares shall vest under this Award Agreement, the Company shall instruct its stock transfer agent to establish a book entry account for your benefit representing the shares of Common Stock issuable upon vesting of the Earned Performance Shares. Such shares of Common Stock shall be immediately transferable by you.

(e)Certain Events. Except to the extent provided in paragraph (3) in the event of a Qualifying Termination or due to your termination without Cause or for Good Reason, in the

event your employment terminates at any time for any reason, any unearned, or any earned but unvested, Performance Shares shall be immediately forfeited, all of your rights with respect thereto shall terminate, and no vesting shall occur after such date. For purposes of this Award Agreement, a “Qualifying Termination” means a termination of your employment due to your death, a Disability or your Retirement at or after your Normal Retirement Date.

(3)Termination of Employment.

(a)During the Performance Period. If your employment with the Company or any of its subsidiaries terminates on or prior to the last day of the Performance Period due to a Qualifying Termination, then a portion of your Target Number of Performance Shares shall remain outstanding and may become earned at the end of the Performance Period, and the remainder of your Target Number of Performance Shares shall be forfeited and will not become earned or vested after such termination of your employment. In such case, the portion of your Target Number of Performance Shares which will remain outstanding and eligible to become earned and vested will be equal to the product of (i) the Target Number of Performance Shares set forth in Paragraph 1 above, multiplied by (ii) a fraction, the numerator of which is the number of whole months which have elapsed from [Start Date] to the date of termination of employment and the denominator of which is 36. Such product shall become your Target Number of Performance Shares for purposes of determining the RTSR-Based Performance Shares and CRATCE-Based Performance Shares under Exhibits A and B, respectively, and the determination of the number of your Earned Performance Shares, if any, following the end the of the Performance Period.

If your employment with the Company or any of its subsidiaries terminates for any other reason on or prior to the last day of the Performance Period, all unearned Performance Shares shall be immediately forfeited and all of your rights hereunder shall terminate.

(b)After the Performance Period. If your employment with the Company or any of its subsidiaries terminates after the completion of the Performance Period (but prior to the time that all of the Earned Performance Shares have become vested) due to a Qualifying Termination, then any unvested Earned Performance Shares shall vest in full on the date of termination and become immediately payable in shares of Common Stock (which shall be freely transferable). If your employment with the Company or any of its subsidiaries terminates without Cause or for Good Reason after the completion of the Performance Period (but prior to the time that all of the Earned Performance Shares have become vested), then a portion of the unvested Earned Performance Shares shall vest in full on the date of termination and become immediately payable in shares of Common Stock (which shall be freely transferable) based on the product of (i) the Earned Performance Shares multiplied by (ii) a fraction, the numerator of which is the number of whole months which have elapsed from [Start Date] to the date of termination of employment and the denominator of which is 60. If your employment with the Company or any of its subsidiaries terminates for any other reason (including for Cause or without Good Reason) after the completion of the Performance Period (but prior to the time that all of the Earned Performance Shares have become vested), then the unvested Earned Performance Shares shall be immediately forfeited and all of your rights hereunder shall terminate.

(c)Upon or After Change in Control. If your employment with the Company or any of its subsidiaries terminates due to a Qualifying Termination, without Cause or for Good Reason upon a Change in Control or within the 24 months after a Change in Control (but prior to the time that all of the Earned Performance Shares have become vested), then any unvested Earned Performance Shares shall vest in full on the date of termination and become immediately payable in shares of Common Stock (which shall be freely transferable). If your employment with the Company or any of its subsidiaries terminates for any other reason (including for Cause or without Good Reason) upon or within the 24 months after a Change in Control (but prior to the time that all of the Earned Performance Shares have become vested), then the unvested Earned Performance Shares shall be immediately forfeited and all of your rights hereunder shall terminate.

(d)Definitions and Determination of Disability, Cause and Good Reason. If you are a party to an employment agreement with the Company or any subsidiary or affiliate of the Company (such agreement the “Employment Agreement”), “Cause” and “Good Reason” shall have the meanings ascribed to such terms in your Employment Agreement. If you do not have an employment agreement with the Company or any subsidiary or affiliate of the Company:

(i)“Cause” shall have the meaning ascribed to it in the Omnibus Plan.

(ii)“Good Reason” shall mean the occurrence of any event, other than in connection with termination of your employment by the Company, which results in (A) a material diminution of your principal duties or responsibilities from those in effect immediately prior to the Change in Control, including, without limitation, a significant change in the nature or scope of your principal duties or responsibilities, such that your duties or responsibilities are inconsistent with those immediately prior to the Change in Control, and commonly (in the banking industry) considered to be of lesser responsibility, or (B) a material diminution of your compensation from that immediately prior to the Change in Control, or (C) you being required to be based at an office or location which is more than 35 miles from your office or location immediately prior to the Change in Control. Notwithstanding the foregoing, in order for your resignation for Good Reason to occur, (x) you must provide written notice of the Good Reason event to the Company or its subsidiary within 90 days after the initial existence of such event, (y) the Company or its subsidiary must not have cured such condition within 30 days of receipt of your written notice or the Company or its subsidiary must have stated unequivocally in writing that it does not intend to attempt to cure such condition; and (z) you must resign from employment at the end of the period within which the Company or a subsidiary was entitled to remedy the condition constituting Good Reason but failed to do so.

For purposes of this Award Agreement, the determination of whether a termination of your employment is for a “Disability”, for “Cause” or for “Good Reason” shall be determined in accordance with the Omnibus Plan and this Award Agreement, unless you are party to an Employment Agreement, in which case such determination under your Employment Agreement will control.

(4)Effect of a Change in Control.

(a)In the event and concurrently with the effectiveness of a Change in Control during the Performance Period, the Performance Period shall end and the number of Earned Performance Shares shall be determined and certified by the Compensation Committee for both performance goals either (i) in accordance with Exhibits A and B or (ii) at the target award level for each performance goal specified in Exhibits A and B, whichever is greater. Such Earned Performance Shares will vest and become payable in shares of Common Stock (which shall be freely transferable) in equal annual installments on the first regular payroll day following the Change in Control and the first and second anniversaries of the Change in Control, if you are continuously employed by the Company or any of its subsidiaries through such dates, subject to earlier vesting in accordance with paragraph (4)(c) below or in the event of your termination as provided in paragraph (3)(c) above.

(b)In the event of a Change in Control after the completion of the Performance Period (but prior to the time that all of the Earned Performance Shares have become vested), the Earned Performance Shares will continue to vest as provided in paragraph (2)(d), subject to earlier vesting in accordance with paragraph (4)(c) below or in the event of your termination as provided in paragraph (3)(c) above.

(c)A Change in Control shall not, by itself, result in acceleration of vesting of the Earned Performance Shares, except as provided in this paragraph (4)(c).

(i)Upon a Change in Control, the Earned Performance Shares (as determined in accordance with paragraph (4)(a) above) will vest in full and become Common Stock (which shall be freely transferable) unless another award meeting the requirements of this paragraph (4)(c) (a “Substitute Award”) is provided to you to replace this Award (the “Original Award”), in which case such Substitute Award shall vest and become payable in accordance with paragraphs (4)(a) and (4)(b) above. Each Earned Performance Share will represent the right to receive one share of Common Stock (less any shares withheld in satisfaction of tax withholding obligations under paragraph (8), if any).

(ii)An award shall meet the requirements of this paragraph (4)(c), and thereby qualify as a Substitute Award, if the following conditions are met:

(1)The award has a value at least equal to the value of the Original Award;

(2)The award relates to publicly-traded equity securities of the Company or its successor following the Change in Control or another entity that is affiliated with the Company or its successor following the Change in Control; and

(3)The other terms and conditions of the award are not less favorable to you than the terms and conditions of the Original Award, including the vesting provisions of paragraph (3)(c) above (except that in the event of a subsequent

Change in Control of the Company or its successor, the Substitute Award shall be fully vested and freely transferable upon such subsequent Change in Control).

Without limiting the generality of the foregoing, a Substitute Award may take the form of a continuation of the Original Award if the requirements of the preceding sentence are satisfied. The determination of whether the conditions of this paragraph 4 are satisfied shall be made by the Committee, as constituted immediately before the Change in Control, in its sole discretion.

(5)Non-Transferability. This Award is personal to you and, until vested and transferable hereunder, may not be sold, transferred, pledged, assigned or otherwise alienated, otherwise than by will or by the laws of descent and distribution.

(6)Securities Law Restrictions. You understand and acknowledge that applicable securities laws govern and may restrict your right to offer, sell or otherwise dispose of any Common Stock received under the Award.

Executive Officers of the Company subject to the two (2) day reporting rules of Section 16(a) and short-swing profit recovery rules of Section 16(b) of the Securities Exchange Act of 1934 should consult the Company’s Corporate Secretary prior to selling any such shares.

(7)Stockholder Rights. Because this is an Award of Performance Shares and not actual shares of Common Stock, you will not have any rights of a stockholder with respect to the Performance Shares. Upon the vesting of the Earned Performance Shares in accordance with this Award Agreement, the Earned Performance Shares will be paid to you in shares of Common Stock (which shall be freely transferable). All cash dividends and cash distributions paid or made available with respect to the Common Stock during the period that the Performance Shares are unearned or unvested will also be paid or made available as if each Performance Share was a share of Common Stock, but such dividends and distributions shall be held by the Company and paid to you on the applicable vesting date for the Performance Shares. In addition, the number of Performance Shares and other provisions of this Award are subject to adjustment pursuant to Section 5.4 of the Omnibus Plan in the event of a stock dividend, stock split or other corporate change described therein.

The Performance Shares are not subject to or eligible for inclusion in the First Midwest Bancorp, Inc. Dividend Reinvestment and Stock Purchase Plan.

(8)Withholding. You shall pay all applicable federal, state and local income and employment taxes (including taxes of any foreign jurisdiction) which the Company is required to withhold at any time with respect to the Earned Performance Shares, which will generally occur as the Earned Performance Shares vest. Payment of withholding obligations upon vesting of the Shares will be accomplished through withholding by the Company of Earned Performance Shares then vesting under this Award with a value equal to such minimum statutory withholding amount, or such greater amount as the Compensation Committee may authorize, provided the withholding of such greater amount does not result in adverse accounting consequences for the Company. Shares withheld as payment of required withholding shall be valued at Fair Market Value on the date such withholding obligation arises.

(9)Tax Consequences. Information regarding federal tax consequences of the Award can be found in the Omnibus Plan’s “Summary Description”. You are strongly encouraged to contact your tax advisor regarding such tax consequences as they relate to you.

(10)Employment; Future Awards; Successors. Nothing herein confers any right or obligation on you to continue in the employment of the Company or any subsidiary or shall affect in any way your right or the right of the Company or any subsidiary, as the case may be, to terminate your employment at any time, subject to the terms of any employment agreement to which the Company and you may be parties. Nothing herein shall create any right for you to receive, or obligation on the part of the Company to grant to you, any future Awards under the Omnibus Plan. This Agreement shall be binding upon, and inure to the benefit of, any successor or successors of the Company.

Exhibit A to Performance Shares Award Agreement

(Relative TSR-Based Performance Measure)

References herein to “Award Agreement” shall mean the Performance Shares Award Award Agreement to which this Exhibit is attached and references to “Grantee” shall mean you.

(1)Relative TSR-Based Performance Goals.

(a)Target and Maximum Number of Performance Shares. The number of Performance Shares equal to 50% of the Target Number of Performance Shares set forth in Paragraph (1) of the Award Agreement (or, the applicable portion thereof as determined under Paragraph 3(a) of the Award Agreement in the event of termination of employment for reasons described in such Paragraph 3(a)) shall be subject to the provisions of this Exhibit A. Such number of Performance Shares are referred to in the Award Agreement and this Exhibit A as the “RTSR-Based Performance Shares”. The maximum number of Performance Shares which may be determined to be Earned Performance Shares under the provisions of this Exhibit A shall be two times the number of RTSR-Based Performance Shares.

(b)Performance Goal. The performance goal applicable to the RTSR-Based Performance Shares is relative Total Shareholder Return, or “RTSR”, for the Performance Period.

(c)Certification of Achievement Relative to Performance Goal. Following the end of the Performance Period, the Compensation Committee will certify the level of the RTSR performance goal achieved by the Company. Performance at or above the threshold level set forth below will result in RTSR-Based Performance Shares becoming earned (“Earned Performance Shares”). The certification of the level of the RTSR performance goal achieved and the number of Earned Performance Shares shall occur no later than sixty days after the end of the Performance Period. Such certification and determination shall be made as described in Section 3 below. Earned Performance Shares will vest as set forth in the Award Agreement. Performance Shares will be forfeited and cancelled in full if the Company’s performance during the Performance Period does not meet or exceed the threshold percentile rank of the RTSR performance goal. To the extent the Earned Performance Shares are less than the number of RTSR-Based Performance Shares, such excess RTSR-Based Performance Shares shall be forfeited and cancelled.

(2)Definitions. For purposes of this Exhibit A, the following terms will have the meanings set forth below:

(a)“Comparison Group” means the companies listed on Appendix 1 to this Exhibit A, as may be adjusted as described below.

(b)“Performance Period” means the three-year period commencing [Start Date] and ending [End Date].

(c)“Total Shareholder Return” or “TSR” means total shareholder return as applied to the Company or any company in the Comparison Group, meaning common stock price appreciation

from the beginning to the end of the Performance Period, plus dividends and distributions made or declared (assuming such dividends or distributions are reinvested in the common stock of the Company or any company in the Comparison Group) during the Performance Period, expressed as a percentage return. If a company: (i) files for bankruptcy, reorganization or liquidation under any chapter of the U.S. Bankruptcy Code; (ii) is the subject of an involuntary bankruptcy proceeding that is not dismissed within 30 days; (iii) is the subject of a stockholder approved plan of liquidation or dissolution; or (iv) ceases to conduct substantial business operations other than by virtue of a merger, consolidation, share exchange or similar transaction, then the TSR for that company will be negative one hundred percent (-100%).

(d)Other Capitalized Terms. All capitalized terms used but not otherwise defined in this Exhibit A shall have the same definitions stated in the Award Agreement or the Omnibus Plan, as applicable.

(3)Calculation. For purposes of this Exhibit A, the number of RTSR-Based Performance Shares which shall become Earned Performance Shares will be calculated as follows:

FIRST: For the Company and for each other company in the Comparison Group, determine the TSR for the Performance Period.

SECOND: Rank the TSR values determined in the first step from low to high (with the company having the lowest TSR being ranked number 1, the company with the second lowest TSR ranked number 2, and so on) and determine the Company’s percentile rank based upon its position in the list by dividing the Company’s position by the total number of companies (including the Company) in the Comparison Group and rounding the quotient to the nearest hundredth. For example, if the Company were ranked [__] on the list out of [__] companies (including the Company), its percentile rank would be [__]%.

THIRD: Plot the percentile rank for the Company determined in the second step into the appropriate band in the left-hand column of the table below and determine the number of RTSR-Based Performance Shares earned as a percent of the number of RTSR-Based Performance Shares, which is the figure in the right-hand column of the table below corresponding to that percentile rank. Use linear interpolation between points in the table below to determine the percentile rank and the corresponding share funding if the Company’s percentile rank is greater than [__]% and less than [__]% but not exactly one of the percentile ranks listed in the left-hand column. For example, if the Company’s percentile rank is [__]%, then the number of Earned Performance Shares would be equal to [__]% of the RTSR-Based Performance Shares.

PERCENTILE RANK	% RTSR-BASED PERFORMANCE SHARES EARNED
	(Threshold)
	(Target)
	200%

(4)Rules. The following rules apply to the computation of the number of RTSR-Based Performance Shares earned:

(a)No Guaranteed Payout. The minimum number of RTSR-Based Performance Shares which may be earned is zero and the maximum number of RTSR-Based Performance Shares which may be earned is two times the number of RTSR-Based Performance Shares.

(b)Averaging Period. For purposes of computing Total Shareholder Return for the Company and each other company in the Comparison Group, the common stock price at the beginning and end of the Performance Period will, subject to Section 5 below, be determined as the 20-day average of the closing price of the common stock on each of the 20 consecutive trading days ending on and including the first day or last day of the Performance Period, as the case may be.

(c)Effect of Specified Corporate Change on Comparison Group. Companies shall be removed from the Comparison Group if they undergo a Specified Corporate Change. A company that is removed from the Comparison Group before the end of a Performance Period will not be included at all in the calculation of Total Shareholder Return and the computation of the number of Performance Shares earned for that Performance Period. A company in the Comparison Group will be deemed to have undergone a “Specified Corporate Change” if it:

(i) ceases to be a domestically domiciled publicly traded company on a national stock exchange or market system, unless such cessation of such listing is due to a low stock price or low trading volume; or

(ii) has gone private; or

(iii) has reincorporated in a foreign (e.g., non-U.S.) jurisdiction, regardless of whether it is a reporting company in that or another jurisdiction; or

(iv) has been acquired by or merged into another company (whether by another company in the Comparison Group or otherwise, but not including internal reorganizations), or has sold all or substantially all of its assets.

The Company shall rely on press releases, public filings, website postings and other reasonably reliable information available regarding a Comparison Company in making a determination that a Specified Corporate Change has occurred.

(5)Effect of Certain Events. The following provisions will apply in the event of the termination of employment of the Grantee or the occurrence of a Change in Control:

(a)Termination of Employment Prior to a Change in Control. The effect of termination of employment prior to a Change in Control shall be governed by paragraph (3) of the attached Award Agreement.

(b)Effect of Change in Control. In the event of a Change in Control, the number of RTSR-Based Performance Shares that shall be earned, vested and payable in Common Stock shall be calculated and determined by the Compensation Committee in accordance with paragraph (4) of the Award Agreement and this Section as follows:

FIRST: If the Performance Period has not been completed, there shall be determined the number of RTSR-Based Performance Shares that would be earned if the Performance Period was the period which began on [Start Date] and ended on the date which is five trading days prior to the effective date of the Change in Control. The Company TSR for purposes of this calculation shall be determined using the per share value of the common stock as of the effective date of the Change in Control instead of a 20-trading day average ending on the last day of the Performance Period. The Compensation Committee shall determine the number of Earned Performance Shares in accordance with Sections 1(c) and 3 above.

Notwithstanding the foregoing, if the number of earned RTSR-Based Performance Shares determined using the calculation in the preceding paragraph is less than 50% of the Target Number of Performance Shares, then the number of Earned Performance Shares based on the RTSR performance goal shall be equal to 50% of the Target Number of Performance Shares.

SECOND: If the Performance Period has been completed, then the Earned Performance Shares shall be equal to the number determined in accordance with Sections 1(c) and 3 above.

The Earned Performance Shares shall vest in accordance with paragraphs (3) and (4) of the Award Agreement.

Exhibit B to Performance Shares Award Agreement

(CRATCE-Based Performance Measure)

References herein to “Award Agreement” shall mean the Performance Shares Award Agreement to which this Exhibit is attached and references to “Grantee” shall mean you.

(1)CRATCE-Based Performance Goal.

(a)Target and Maximum Number of Performance Shares. The number of Performance Shares equal to 50% of the Target Number of Performance Shares set forth in Paragraph (1) of the Award Agreement (or, the applicable portion thereof as determined under Paragraph 3(a) of the Award Agreement in the event of termination of employment for reasons described in such Paragraph 3(a)) shall be subject to the provisions of this Exhibit B. Such number of Performance Shares are referred to in the Award Agreement and this Exhibit B as the “CRATCE-Based Performance Shares”. The maximum number of Performance Shares which may be determined to be Earned Performance Shares under the provisions of this Exhibit B shall be two times the number of CRATCE-Based Performance Shares.

(b)Performance Goal. The performance goal applicable to the CRATCE-Based Performance Shares is the average level of Calendar Year CRATCE achievement against Calendar Year CRATCE Targets established by the Compensation Committee with respect to each Calendar Year during the Performance Period.

(c)Certification of Achievement Relative to Performance Criteria. Following the end of the Performance Period, the Compensation Committee will certify the level of the CRATCE performance goal achieved by the Company. Performance at or above the threshold level set forth as described below will result in CRATCE-Based Performance Shares becoming earned (“Earned Performance Shares”). The certification of the level of the CRATCE performance goal achieved and the number of Earned Performance Shares shall occur no later than sixty days after the end of the Performance Period. Such certification and determination shall be made as described in Section 3 below. Earned Performance Shares will vest as set forth in the Award Agreement. The CRATCE-Based Performance Shares will be forfeited and cancelled in full if the Company’s performance during the Performance Period does not meet or exceed the threshold. To the extent the Earned Performance Shares are less than the number of CRATCE-Based Performance Shares, such unearned CRATCE-Based Performance Shares shall be forfeited and cancelled.

(2)Definitions. For purposes of this Exhibit B, the following terms will have the meanings set forth below:

(a)“Performance Period” means the three-year period commencing [Start Date] and ending [End Date].

The Compensation Committee shall establish the Calendar Year CRATCE Grid for each Calendar Year no later than the 90th day of such Calendar Year. The [Year 1] Calendar Year CRATCE Grid is set forth in Section (3) below.

(e)“Calendar Year CRATCE Payout %” means, with respect to a Calendar Year, the Calendar Year CRATCE Payout % for that year as certified by the Compensation Committee based upon the Calendar Year CRATCE and Calendar Year CRATCE Grid for such Calendar Year.

(f)“Core Return on Average Tangible Common Equity”, or “CRATCE”, means with respect to any specified period, the Company’s Core Net Income for such period divided by the Company’s Average Tangible Common Equity during such period.

(g)“Core Net Income” for any period means the Company’s net income for such period as reported by the Company, but excluding the following:

(i)[__]

(h)“Average Tangible Common Equity” for any period means the average tangible common equity for such period as reported by the Company, with adjustments similar to those adjustments made for purposes of determining Core Net Income also being made to Average Tangible Common Equity to the extent applicable.

(i)“Average Calendar Year CRATCE Payout %” for a period means the average of the Calendar Year CRATCE Payout % for each of the Calendar Years in the Performance Period, provided that in the event of a Change in Control during the Performance Period, the Average Calendar Year CRATCE Payout % shall be determined for the number of full Calendar Years in the Performance Period which have elapsed as of the calendar quarter end immediately preceding the Change in Control (the “Measurement Quarter End”); provided, however, that for this purpose the Calendar Year including the Measurement Quarter End shall be treated as a full Calendar Year and the Calendar Year CRATCE for such year shall be determined by annualizing the Core Net Income through the Measurement Quarter End and dividing that amount by the Average Tangible Common Equity during such Calendar Year through the Measurement Quarter End.

(j)Other Capitalized Terms. All capitalized terms used but not otherwise defined in this Exhibit B shall have the same definitions stated in the Award Agreement or the Omnibus Plan, as applicable.

(3)Calculation. For purposes of this Exhibit B, the number of CRATCE-Based Performance Shares which shall become Earned Performance Shares will be calculated as follows:

FIRST: The Company’s Calendar Year CRATCE for each Calendar Year in the Performance Period shall be determined.

SECOND: Plot the Calendar Year CRATCE determined for each Calendar Year in the first step into the appropriate band in the left-hand column of the Calendar Year CRATCE Grid for such Calendar Year and determine the Calendar Year CRATCE Payout %, which is the figure in the right-hand column of the Calendar Year CRATCE Grid corresponding to that level of Calendar Year CRATCE. Use linear interpolation between points in the table below to determine the corresponding Calendar Year CRATCE Payout % if the Company’s Calendar Year CRATCE is greater than threshold and less than maximum, but not exactly one of the percentages listed in the left-hand column. For example, if the company’s Calendar Year CRATCE in [Year 1] is [__]%, then the Calendar Year CRATCE Payout % would be [__]%.

CALENDAR YEAR CRATCE GRID
2016 CALENDAR YEAR CRATCE	CALENDAR YEAR CRATCE PAYOUT %
	(Threshold)
	(Target)
	(Maximum)

The minimum Calendar Year CRATCE Payout % which may be earned is zero and the maximum is 200%.

THIRD: Determine the number of Earned Performance Shares by multiplying the Average Calendar Year CRATCE Payout % (as determined based upon the Calendar Year CRATCE Payout % amounts determined in the second step) by the number of CRATCE-Based Performance Shares.

(4)Effect of Certain Events. The following provisions will apply in the event of the termination of employment of the Grantee or the occurrence of a Change in Control:

(a)Termination of Employment Prior to a Change in Control. The effect of termination of employment prior to a Change in Control shall be governed by paragraph (3) of the attached Award Agreement.

(b)Effect of Change in Control. In the event of a Change in Control, the number of CRATCE-Based Performance Shares that shall be earned, vested and payable in Common Stock shall be calculated and determined by the Compensation Committee in accordance with paragraph (4) of the Award Agreement and this Section as follows:

FIRST: If the Performance Period has not been completed, there shall be determined the number of CRATCE-Based Performance Shares that would be earned if the Performance Period was the period which began on [Start Date] and ended on the effective date of the Change in Control.

The Compensation Committee shall determine the number of Earned Performance Shares in accordance with Sections 1(c) and 3 above.

Notwithstanding the foregoing, if the number of earned CRATCE-Based Performance Shares determined using the calculation in the preceding paragraph is less than 50% of the Target Number of Performance Shares, then the number of Earned Performance Shares based on the CRATCE performance goal shall be equal to 50% of the Target Number of Performance Shares.

SECOND: If the Performance Period has been completed, then the Earned Performance Shares shall be equal to the number determined in accordance with Sections 1(c) and 3 above.

The Earned Performance Shares shall vest in accordance with paragraphs (3) and (4) of the Award Agreement.

Review Report of Independent Registered Public Accounting Firm

The Board of Directors

First Midwest Bancorp, Inc.

We have reviewed the consolidated statement of financial condition of First Midwest Bancorp, Inc. (the “Company”) as of March 31, 2016, and the related condensed consolidated statements of income and consolidated statements of comprehensive income and changes in stockholders’ equity, and condensed consolidated cash flows for the three-month periods ended March 31, 2016 and 2015. These financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statement of financial condition of the Company as of December 31, 2015, and the related consolidated statements of income, comprehensive income, shareholders’ equity and cash flows for the year then ended (not presented herein) and we expressed an unqualified opinion on those consolidated financial statements in our report dated February 23, 2016.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation – The accompanying unaudited condensed consolidated interim financial statements ("consolidated financial statements") of First Midwest Bancorp, Inc. (the "Company"), a Delaware corporation, were prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") for quarterly reports on Form 10-Q and reflect all adjustments that management deems necessary for the fair presentation of the financial position and results of operations for the periods presented. The results of operations for the quarter ended March 31, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016.

The accounting and reporting policies of the Company and its subsidiaries conform to U.S. generally accepted accounting principles ("GAAP") and general practices within the banking industry. The accompanying consolidated financial statements do not include certain information and note disclosures required by GAAP for complete annual financial statements. Therefore, these financial statements should be read in conjunction with the Company's 2015 Annual Report on Form 10-K ("2015 10-K"). The Company uses the accrual basis of accounting for financial reporting purposes. Certain reclassifications were made to prior year amounts to conform to the current year presentation.

Use of Estimates – The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Although these estimates and assumptions are based on the best available information, actual results could differ from those estimates.

Principles of Consolidation – The accompanying consolidated financial statements include the financial position and results of operations of the Company and its subsidiaries after elimination of all significant intercompany accounts and transactions. Assets held in a fiduciary or agency capacity are not assets of the Company or its subsidiaries and are not included in the consolidated financial statements.

The accounting policies related to business combinations, loans, the allowance for credit losses, and derivative financial instruments are presented below. For a summary of all other significant accounting policies, see Note 1, "Summary of Significant Accounting Policies," in the Company's 2015 10-K.

Business Combinations – Business combinations are accounted for under the acquisition method of accounting. Assets acquired and liabilities assumed are recorded at their estimated fair values as of the date of acquisition, with any excess of the purchase price of the acquisition over the fair value of the identifiable net tangible and intangible assets acquired recorded as goodwill. Alternatively, a gain is recorded if the fair value of assets purchased exceeds the fair value of liabilities assumed and consideration paid. The results of operations of the acquired business are included in the Condensed Consolidated Statements of Income from the effective date of the acquisition.

Loans – Loans held-for-investment are loans that the Company intends to hold until they are paid in full and are carried at the principal amount outstanding, including certain net deferred loan origination fees. Loan origination fees, commitment fees, and certain direct loan origination costs are deferred, and the net amount is amortized as a yield adjustment over the contractual life of the related loans or commitments and included in interest income. Fees related to standby letters of credit are amortized into fee income over the contractual life of the commitment. Other credit-related fees are recognized as fee income when earned. The Company's net investment in direct financing leases is included in loans and consists of future minimum lease payments and estimated residual values, net of unearned income. Interest income on loans is accrued based on principal amounts outstanding. Loans held-for-sale are carried at the lower of aggregate cost or fair value and included in other assets in the Consolidated Statements of Financial Condition.

Acquired and Covered Loans – Covered loans consists of loans acquired by the Company in Federal Deposit Insurance Corporation ("FDIC")-assisted transactions, which are covered by loss share agreements with the FDIC (the "FDIC Agreements"), under which the FDIC reimburses the Company for the majority of the losses and eligible expenses related to these assets during the coverage period. Acquired loans consist of all other loans that were acquired in business combinations that are not covered by FDIC Agreements. Covered loans and acquired loans are included within loans held-for-investment.

Acquired and covered loans are separated into (i) non-purchased credit impaired ("Non-PCI") and (ii) purchased credit impaired ("PCI") loans. Non-PCI loans include loans that did not have evidence of credit deterioration since origination at the acquisition date. PCI loans include loans that had evidence of credit deterioration since origination and for which it was probable at acquisition that the Company would not collect all contractually required principal and interest payments. Evidence of credit deterioration was evaluated using various indicators, such as past due and non-accrual status. Leases and revolving loans do not qualify to be accounted for as PCI loans and are accounted for as Non-PCI loans.

The acquisition adjustment related to Non-PCI loans is amortized into interest income over the contractual life of the related loans. If an acquired non-PCI loan is renewed subsequent to the acquisition date, any remaining acquisition adjustment is accreted into interest income and the loan is considered a new loan that is no longer classified as an acquired loan.

PCI loans are accounted for based on estimates of expected future cash flows. To estimate the fair value, the Company generally aggregates purchased consumer loans and certain smaller balance commercial loans into pools of loans with common risk characteristics, such as delinquency status, credit score, and internal risk ratings. The fair values of larger balance commercial loans are estimated on an individual basis. Expected future cash flows in excess of the fair value of loans at the purchase date ("accretable yield") are recorded as interest income over the life of the loans if the timing and amount of the expected future cash flows can be reasonably estimated. The non-accretable yield represents the difference between contractually required payments and the expected future cash flows determined at acquisition. Subsequent increases in expected future cash flows are offset against the allowance for credit losses to the extent an allowance has been established or otherwise recognized as interest income prospectively. The present value of any decreases in expected future cash flows is recognized by recording a charge-off through the allowance for loan losses or providing an allowance for loan losses.

90-Days Past Due Loans –The Company's accrual of interest on loans is discontinued at the time the loan is 90 days past due unless the credit is sufficiently collateralized and in the process of renewal or collection.

Non-accrual Loans– Generally, corporate loans are placed on non-accrual status (i) when either principal or interest payments become 90 days or more past due unless the credit is sufficiently collateralized and in the process of renewal or collection, or (ii) when an individual analysis of a borrower's creditworthiness warrants a downgrade to non-accrual regardless of past due status. When a loan is placed on non-accrual status, unpaid interest credited to income in the current year is reversed, and unpaid interest accrued in prior years is charged against the allowance for loan losses. After the loan is placed on non-accrual, all debt service payments are applied to the principal on the loan. Future interest income may only be recorded on a cash basis after recovery of principal is reasonably assured. Non-accrual loans are returned to accrual status when the financial position of the borrower and other relevant factors indicate that the Company will collect all principal and interest.

Commercial loans and loans secured by real estate are charged-off when deemed uncollectible. A loss is recorded if the net realizable value of the underlying collateral is less than the outstanding principal and interest. Consumer loans that are not secured by real estate are subject to mandatory charge-off at a specified delinquency date and are usually not classified as non-accrual prior to being charged-off. Closed-end consumer loans, which include installment, automobile, and single payment loans, are usually charged-off no later than the end of the month in which the loan becomes 120 days past due.

PCI loans are generally considered accruing loans unless reasonable estimates of the timing and amount of expected future cash flows cannot be determined. Loans without reasonable future cash flow estimates are classified as non-accrual loans, and interest income is not recognized on those loans until the timing and amount of the expected future cash flows can be reasonably determined.

Troubled Debt Restructurings ("TDRs") – A restructuring is considered a TDR when (i) the borrower is experiencing financial difficulties, and (ii) the creditor grants a concession, such as forgiveness of principal, reduction of the interest rate, changes in payments, or extension of the maturity date. Loans are not classified as TDRs when the modification is short-term or results in an insignificant delay in payments. The Company's TDRs are determined on a case-by-case basis.

The Company does not accrue interest on a TDR unless it believes collection of all principal and interest under the modified terms is reasonably assured. For a TDR to begin accruing interest, the borrower must demonstrate some level of past performance and the future capacity to perform under the modified terms. Generally, six months of consecutive payment performance under the restructured terms is required before a TDR is returned to accrual status. However, the period could vary depending on the individual facts and circumstances of the loan. An evaluation of the borrower's current creditworthiness is used to assess the borrower's capacity to repay the loan under the modified terms. This evaluation includes an estimate of expected future cash flows, evidence of strong financial position, and estimates of the value of collateral, if applicable. For TDRs to be removed from TDR status in the calendar year after the restructuring, the loans must (i) have an interest rate and terms that reflect market conditions at the time of restructuring, and (ii) be in compliance with the modified terms. If the loan was restructured at below market rates and terms, it continues to be separately reported as restructured until it is paid in full or charged-off.

Impaired Loans – Impaired loans consist of corporate non-accrual loans and TDRs. A loan is considered impaired when it is probable that the Company will not collect all contractual principal and interest. With the exception of accruing TDRs, impaired loans are classified as non-accrual and are exclusive of smaller homogeneous loans, such as home equity, 1-4 family mortgages, and installment loans. Impaired loans with balances under a specified threshold are not individually evaluated for impairment. For all other impaired loans, impairment is measured by comparing the estimated value of the loan to the recorded book value. The value of collateral-dependent loans is based on the fair value of the underlying collateral, less costs to sell. The value of other loans is measured using the present value of expected future cash flows discounted at the loan's initial effective interest rate.

Allowance for Credit Losses – The allowance for credit losses is comprised of the allowance for loan losses and the reserve for unfunded commitments, and is maintained by management at a level believed adequate to absorb estimated losses inherent in the existing loan portfolio. Determination of the allowance for credit losses is subjective since it requires significant estimates and management judgment, including the amounts and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans, consideration of current economic trends, and other factors.

Loans deemed to be uncollectible are charged-off against the allowance for loan losses, while recoveries of amounts previously charged-off are credited to the allowance for loan losses. Additions to the allowance for loan losses are charged to expense through the provision for loan losses. The amount of provision depends on a number of factors, including net charge-off levels, loan growth, changes in the composition of the loan portfolio, and the Company's assessment of the allowance for loan losses based on the methodology discussed below.

Allowance for Loan Losses– The allowance for loan losses consists of (i) specific reserves for individual loans where the recorded investment exceeds the value, (ii) an allowance based on a loss migration analysis that uses historical credit loss experience for each loan category, and (iii) an allowance based on other internal and external qualitative factors.

The specific reserves component of the allowance for loan losses is based on a periodic analysis of impaired loans exceeding a fixed dollar amount. If the value of an impaired loan is less than the recorded book value, the Company either establishes a valuation allowance (i.e., a specific reserve) equal to the excess of the book value over the value of the loan as a component of the allowance for loan losses or charges off the amount if it is a confirmed loss.

The general reserve component is based on a loss migration analysis, which examines actual loss experience by loan category for a rolling 8-quarter period and the related internal risk rating for corporate loans. The loss migration analysis is updated quarterly primarily using actual loss experience. This component is then adjusted based on management's consideration of many internal and external qualitative factors, including:

• Changes in the composition of the loan portfolio, trends in the volume of loans, and trends in delinquent and non-accrual loans that could indicate that historical trends do not reflect current conditions.

• Changes in credit policies and procedures, such as underwriting standards and collection, charge-off, and recovery practices.

• Changes in the experience, ability, and depth of credit management and other relevant staff.

• Changes in the quality of the Company's loan review system and Board of Directors oversight.

• The effect of any concentration of credit and changes in the level of concentrations, such as loan type or risk rating.

• Changes in the value of the underlying collateral for collateral-dependent loans.

• Changes in the national and local economy that affect the collectability of various segments of the portfolio.

• The effect of other external factors, such as competition and legal and regulatory requirements, on the Company's loan portfolio.

The allowance for loan losses also consists of an allowance on acquired and covered Non-PCI and PCI loans. No allowance for loan losses is recorded on acquired loans at the acquisition date. Subsequent to the acquisition date, an allowance for credit losses is established as necessary to reflect credit deterioration. The acquired Non-PCI allowance is based on management's evaluation of the acquired Non-PCI loan portfolio giving consideration to the current portfolio balance including the remaining acquisition adjustments, maturity dates, and overall credit quality. The allowance for covered Non-PCI loans is calculated in the same manner as the general reserve component based on a loss migration analysis as discussed above. The acquired and covered PCI allowance reflects the difference between the carrying value and the discounted expected future cash flows of the acquired and covered PCI loans. On a periodic basis, the adequacy of this allowance is determined through a re-estimation of expected future cash flows on all the outstanding acquired and covered PCI loans using either a probability of default/loss given default ("PD/LGD") methodology or a specific review methodology. The PD/LGD model is a loss model that estimates expected future cash flows using a probability of default curve and loss given default estimates. Acquired Non-PCI loans that have renewed subsequent to the respective acquisition dates are no longer classified as acquired loans. Instead, they are included with our general loan population and allocated an allowance based on a loss migration analysis.

Reserve for Unfunded Commitments– The Company also maintains a reserve for unfunded commitments, including letters of credit, for the risk of loss inherent in these arrangements. The reserve for unfunded commitments is estimated using the loss migration analysis from the allowance for loan losses, adjusted for probabilities of future funding requirements. The reserve for unfunded commitments is included in other liabilities in the Consolidated Statements of Financial Condition.

The establishment of the allowance for credit losses involves a high degree of judgment given the difficulty of assessing the factors impacting loan repayment and estimating the timing and amount of losses. While management utilizes its best judgment and information available, the adequacy of the allowance for credit losses depends on a variety of factors beyond the Company's control, including the performance of its loan portfolio, the economy, changes in interest rates and property values, and the interpretation of loan risk classifications by regulatory authorities.

Derivative Financial Instruments – To provide derivative products to customers and in the ordinary course of business, the Company enters into derivative transactions as part of its overall interest rate risk management strategy to minimize significant unplanned fluctuations in earnings and expected future cash flows caused by interest rate volatility. All derivative instruments are recorded at fair value as either other assets or other liabilities in the Consolidated Statements of Financial Condition. Subsequent changes in a derivative's fair value are recognized in earnings unless specific hedge accounting criteria are met.

On the date the Company enters into a derivative contract, the derivative is designated as a fair value hedge, a cash flow hedge, or a non-hedge derivative instrument. Fair value hedges are designed to mitigate exposure to changes in the fair value of an asset or liability attributable to a particular risk, such as interest rate risk. Cash flow hedges are designed to mitigate exposure to variability in expected future cash flows to be received or paid related to an asset, liability, or other type of forecasted transaction. The Company formally documents all relationships between hedging instruments and hedged items, including its risk management objective and strategy at inception.

At the hedge's inception and quarterly thereafter, a formal assessment is performed to determine the effectiveness of the derivative in offsetting changes in the fair values or expected future cash flows of the hedged items in the current period and prospectively. If a derivative instrument designated as a hedge is terminated or ceases to be highly effective, hedge accounting is discontinued prospectively, and the gain or loss is amortized into earnings. For fair value hedges, the gain or loss is amortized over the remaining life of the hedged asset or liability. For cash flow hedges, the gain or loss is amortized over the same period that the forecasted hedged transactions impact earnings. If the hedged item is disposed of, any fair value adjustments are included in the gain or loss from the disposition of the hedged item. If the forecasted transaction is no longer probable, the gain or loss is included in earnings immediately.

For fair value hedges, changes in the fair value of the derivative instruments, as well as changes in the fair value of the hedged item, are recognized in earnings. For cash flow hedges, the effective portion of the change in fair value of the derivative instrument is reported as a component of accumulated other comprehensive loss and is reclassified to earnings when the hedged transaction is reflected in earnings.

Ineffectiveness is calculated based on the change in fair value of the hedged item compared with the change in fair value of the hedging instrument. For all types of hedges, any ineffectiveness in the hedging relationship is recognized in earnings during the period the ineffectiveness occurs.

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Pronouncements

RECENT ACCOUNTING PRONOUNCEMENTS

Adopted Accounting Pronouncements

Amendments to Consolidation Analysis: In February 2015, the Financial Accounting Standards Board ("FASB") issued guidance that updates current accounting for the consolidation of certain legal entities. This guidance modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs") or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, affects the consolidation analysis of reporting entities that are involved with VIEs, and provides certain exceptions from consolidation guidance for certain reporting entities. This guidance is effective for annual and interim periods beginning after December 15, 2015. The adoption of this guidance on January 1, 2016 did not materially impact the Company's financial condition, results of operations, or liquidity.

Simplifying the Presentation of Debt Issuance Costs: In April of 2015, the FASB issued guidance to clarify the presentation of debt issuance costs within the balance sheet. Additionally, the guidance requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this amendment. The guidance is effective for annual and interim periods beginning after December 15, 2015. The adoption of this guidance on January 1, 2016 did not materially impact the Company's financial condition, results of operations, or liquidity.

Accounting Pronouncements Pending Adoption

Revenue from Contracts with Customers: In May of 2014, the FASB issued guidance that requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In March of 2016, the FASB issued an amendment to this guidance to clarify the implementation of guidance on principal versus agent consideration. An additional amendment to clarify the implementation guidance on the identification of performance obligations and licensing was issued in April of 2016.

The guidance was initially effective for annual and interim reporting periods beginning on or after December 15, 2016. In August of 2015, the FASB issued guidance that defers the effective date by one year. The deferral causes the guidance to be effective for annual and interim reporting periods beginning on or after December 15, 2017, and must be applied either retrospectively or using the modified retrospective approach. Early adoption is permitted, but not before the original effective date. Management is evaluating the new guidance, but does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern: In August of 2014, the FASB issued guidance that requires management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued. The guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Amendments to Guidance on Classifying and Measuring Financial Instruments: In January of 2016, the FASB issued guidance that will require entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value. Any changes in fair value will be recognized in net income unless the investments qualify for a new practicability exception. This guidance also requires entities to recognize changes in instrument-specific credit risk related to financial liabilities measured under the fair value option in other comprehensive income. No changes were made to the guidance for classifying and measuring investments in debt securities and loans. This guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Leases: In February of 2016, the FASB issued guidance to increase transparency and comparability across entities for leasing arrangements. This guidance requires lessees to recognized assets and liabilities for most leases. For lessors, this guidance modifies the lease classification criteria and the accounting for sales-type and direct financing leases. In addition, this guidance clarifies criteria for the determination of whether a contract is or contains a lease. This guidance is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted. Management is evaluating the new guidance and the impact to the Company's financial condition, results of operations, and liquidity.

Contingent Put and Call Options in Debt Instruments: In March of 2016, the FASB issued final guidance clarifying the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. Entities are required to apply the guidance to existing debt instruments (or hybrid financial instruments that are determined to have a debt host) using a modified retrospective transition method as of the period of adoption. This guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Equity Method Accounting: In March of 2016, the FASB issued final guidance to simplify the equity method of accounting. The guidance eliminates the requirement to retrospectively apply equity method accounting in previous periods when an investor initially obtains significant influence over an investee. This guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Accounting for Employee Share-based Payments: In March of 2016, the FASB issued guidance to simplify the accounting for employee share-based payment transactions. The guidance requires entities to recognize the income tax effects of awards in the income statement when the awards vest or are settled. In addition, the guidance allows entities to repurchase more of an employee's shares than it can under current guidance for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. This guidance is effective for annual and interim reporting periods beginning on or after December 15, 2016. Early adoption is permitted. Management is evaluating the new guidance, but does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Investments, Debt and Equity Securities [Abstract]

Securities

SECURITIES

Securities are classified as held-to-maturity, trading, or available-for-sale at the time of purchase. Securities classified as held-to-maturity are securities for which management has the intent and ability to hold to maturity and are stated at cost.

The Company's trading securities consist of diversified investment securities reported at fair value that are held in a grantor trust under deferred compensation arrangements in which plan participants may direct amounts earned to be invested in securities other than Company stock.

All other securities are classified as available-for-sale and are carried at fair value with unrealized gains and losses, net of related deferred income taxes, recorded in stockholders' equity as a separate component of accumulated other comprehensive loss.

A summary of the Company's securities portfolio by category and maturity is presented in the following tables.

Purchases and sales of securities are recognized on a trade date basis. Realized securities gains or losses are reported in net securities gains in the Condensed Consolidated Statements of Income. The cost of securities sold is based on the specific identification method. During the quarters ended March 31, 2016 and 2015 there were no material gross trading gains (losses). The following table presents net realized gains on available-for-sale securities for the quarters ended March 31, 2016 and 2015.

Securities Available-for-Sale Gains

(Dollar amounts in thousands)

	Quarters Ended   March 31,
	2016			2015
Gains on sales of securities:
Gross realized gains	$	930		$	650
Gross realized losses	(43		)	(138		)
Net realized gains on sales of securities	887			512
Non-cash impairment charges:
Other-than-temporary securities impairment ("OTTI")	—			—
Net realized gains	$	887		$	512

Accounting guidance requires that the credit portion of an OTTI charge be recognized through income. If a decline in fair value below carrying value is not attributable to credit deterioration and the Company does not intend to sell the security or believe it would not be more likely than not required to sell the security prior to recovery, the Company records the non-credit related portion of the decline in fair value in other comprehensive income.

The following table presents a rollforward of life-to-date OTTI recognized in earnings related to all securities available-for-sale held by the Company for the quarters ended March 31, 2016 and 2015. The majority of the beginning and ending balance of OTTI relates to CDOs currently held by the Company.

Substantially all of the Company's CMOs and other MBSs are either backed by U.S. government-owned agencies or issued by U.S. government-sponsored enterprises. Municipal securities are issued by municipal authorities, and the majority are supported by third party insurance or some other form of credit enhancement. Management does not believe any of these securities with unrealized losses as of March 31, 2016 represent OTTI related to credit deterioration. These unrealized losses are attributed to changes in interest rates and temporary market movements. The Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell them before recovery of their amortized cost basis, which may be at maturity.

The unrealized losses on CDOs as of March 31, 2016 reflect changes in market activity for these securities. Management does not believe these unrealized losses represent OTTI related to credit deterioration. In addition, the Company does not intend to sell the CDOs with unrealized losses within a short period of time, and the Company does not believe it is more likely than not that it will be required to sell them before recovery of their amortized cost basis, which may be at maturity. Significant judgment is required to calculate the fair value of the CDOs, all of which are pooled. For a detailed discussion of the CDO valuation methodology, see Note 14, "Fair Value."

For TDRs to be removed from TDR status in the calendar year after the restructuring, the loans must (i) have an interest rate and terms that reflect market conditions at the time of restructuring, and (ii) be in compliance with the modified terms. Loans that were not restructured at market rates and terms, that are not in compliance with the modified terms, or for which there is a concern about the future ability of the borrower to meet its obligations under the modified terms, continue to be separately reported as restructured until paid in full or charged-off.

There were no material commitments to lend additional funds to borrowers with TDRs as of March 31, 2016 and December 31, 2015.

⁽¹⁾  The junior subordinated debentures related to GLST II and GLST III were assumed by the Company during 2014 through the acquisition of Great Lakes Financial Resources, Inc., the holding company for Great Lakes Bank. As of March 31, 2016 and December 31, 2015, these amounts include acquisition adjustments which resulted in a discount of $1.9 million to GLST II and $2.5 million to GLST III.

⁽²⁾  The interest rates are a variable rate based on the three-month LIBOR plus 1.400% and 1.700% for GLST II and GLST III, respectively.

On April 1, 2016 the $38.5 million in subordinated notes matured and were repaid by the Company. In November of 2016 $114.9 million of senior notes will mature.

Junior Subordinated Debentures

FMCT, GLST II and GLST III are Delaware statutory business trusts. These trusts were established for the purpose of issuing trust-preferred securities and lending the proceeds to the Company in return for junior subordinated debentures of the Company. The junior subordinated debentures are the sole assets of each trust. Therefore, each trust's ability to pay amounts due on the trust-preferred securities is solely dependent on the Company making payments on the related junior subordinated debentures. The trust-preferred securities are subject to mandatory redemption, in whole or in part, on repayment of the junior subordinated debentures at the stated maturity date or on redemption. The Company guarantees payments of distributions and redemptions on the trust-preferred securities on a limited basis.

Trust-preferred securities are included in Tier 1 capital of the Company for regulatory capital purposes. The statutory trusts qualify as VIEs for which the Company is not the primary beneficiary. Consequently, the accounts of those entities are not consolidated in the Company's financial statements.

Derivative Instruments and Hedging Activities

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

In the ordinary course of business, the Company enters into derivative transactions as part of its overall interest rate risk management strategy. The significant accounting policies related to derivative instruments and hedging activities are presented in Note 1, "Summary of Significant Accounting Policies."

Fair Value Hedges

The Company hedges the fair value of fixed rate commercial real estate loans using interest rate swaps through which the Company pays fixed amounts and receives variable amounts. These derivative contracts are designated as fair value hedges.

Fair Value Hedges

(Dollar amounts in thousands)

	As of
	March 31, 2016			December 31, 2015
Gross notional amount outstanding	$	11,320		$	11,620
Derivative liability fair value	(612		)	(643		)
Weighted-average interest rate received	2.35		%	2.25		%
Weighted-average interest rate paid	6.35		%	6.36		%
Weighted-average maturity (in years)	1.73			1.97
Fair value of assets needed to settle derivative transactions (1)	$	633		$	665

⁽¹⁾  This amount represents the fair value if credit risk related contingent features were triggered.

Hedge ineffectiveness is recognized in other noninterest income in the Condensed Consolidated Statements of Income. For the quarters ended March 31, 2016 and 2015, gains or losses related to fair value hedge ineffectiveness were not material.

Cash Flow Hedges

As of March 31, 2016, the Company hedged $710.0 million of certain corporate variable rate loans using interest rate swaps through which the Company receives fixed amounts and pays variable amounts. The Company also hedged $510.0 million of borrowed funds using forward starting interest rate swaps through which the Company receives variable amounts and pays fixed amounts. These transactions allow the Company to add stability to net interest income and manage its exposure to interest rate movements. Forward starting interest rate swaps of $62.5 million and $200.0 million began during the second and third quarters of 2015, respectively, and mature during the same periods in 2019. The remaining forward starting interest rate swaps begin at various dates between June 2016 and March 2018 and mature between June 2019 and May 2020. These derivative contracts are designated as cash flow hedges.

Cash Flow Hedges

(Dollar amounts in thousands)

	As of
	March 31, 2016			December 31, 2015
Gross notional amount outstanding	$	1,220,000		$	1,220,000
Derivative asset fair value	17,121			4,787
Derivative liability fair value	(17,009		)	(8,950		)
Weighted-average interest rate received	1.31		%	1.24		%
Weighted-average interest rate paid	0.90		%	0.75		%
Weighted-average maturity (in years)	3.56			3.91

The effective portion of gains or losses on cash flow hedges is recorded in accumulated other comprehensive loss on an after-tax basis and is subsequently reclassified to interest income or expense in the period that the forecasted hedge impacts earnings. Hedge effectiveness is determined using a regressionanalysis at the inception of the hedge relationship and on an ongoing basis. For the quarters ended March 31, 2016 and 2015, there were no material gains or losses related to cash flow hedge ineffectiveness. As of March 31, 2016, the Company estimates that $3.9 million will be reclassified from accumulated other comprehensive loss as an increase to interest income over the next twelve months.

Other Derivative Instruments

The Company also enters into derivative transactions with its commercial customers and simultaneously enters into an offsetting interest rate derivative transaction with a third party. This transaction allows the Company's customers to effectively convert a variable rate loan into a fixed rate loan. Due to the offsetting nature of these transactions, the Company does not apply hedge accounting treatment. The Company's credit exposure on these derivative transactions results primarily from counterparty credit risk. The credit valuation adjustment ("CVA") is a fair value adjustment to the derivative to account for this risk. As of March 31, 2016 and December 31, 2015, the CVA was not material. Transaction fees related to commercial customer derivative instruments of $3.2 million and $662,000 were recorded in noninterest income for the quarters ended March 31, 2016 and 2015, respectively.

Other Derivative Instruments

(Dollar amounts in thousands)

	As of
	March 31, 2016			December 31, 2015
Gross notional amount outstanding	$	1,023,359		$	853,385
Derivative asset fair value	23,212			11,446
Derivative liability fair value	(23,212		)	(11,446		)
Fair value of assets needed to settle derivative transactions (1)	23,743			11,939

⁽¹⁾  This amount represents the fair value if credit risk related contingent features were triggered.

The Company occasionally enters into risk participation agreements with counterparty banks to transfer or assume a portion of the credit risk related to customer transactions. The amounts of these instruments were not material for any periods presented. The Company had no other derivative instruments as of March 31, 2016 and December 31, 2015. The Company does not enter into derivative transactions for purely speculative purposes.

Credit Risk

Derivative instruments are inherently subject to credit risk, which represents the Company's risk of loss when the counterparty to a derivative contract fails to perform according to the terms of the agreement. Credit risk is managed by limiting and collateralizing the aggregate amount of net unrealized losses by transaction, monitoring the size and the maturity structure of the derivatives, and applying uniform credit standards. Company policy establishes limits on credit exposure to any single counterparty. In addition, the Company established bilateral collateral agreements with derivative counterparties that provide for exchanges of marketable securities or cash to collateralize either party's net losses above a stated minimum threshold. As of March 31, 2016 and December 31, 2015, these collateral agreements covered 100% of the fair value of the Company's outstanding fair value hedges. Derivative assets and liabilities are presented gross, rather than net, of pledged collateral amounts.

Certain derivative instruments are subject to master netting agreements with counterparties. The Company records these transactions at their gross fair values and does not offset derivative assets and liabilities in the Consolidated Statements of Financial Condition. The following table presents the fair value of the Company's derivatives and offsetting positions as of March 31, 2016 and December 31, 2015.

As of March 31, 2016 and December 31, 2015, the Company's derivative instruments generally contained provisions that require the Company's debt to remain above a certain credit rating by each of the major credit rating agencies or that the Company maintain certain capital levels. If the Company's debt were to fall below that credit rating or the Company's capital were to fall below the required levels, it would be in violation of those provisions, and the counterparties to the derivative instruments could terminate the swap transaction and demand cash settlement of the derivative instrument in an amount equal to the derivative liability fair value. As of March 31, 2016 and December 31, 2015 the Company was not in violation of these provisions.

Commitments, Guarantees, and Contingent Liabilities

COMMITMENTS, GUARANTEES, AND CONTINGENT LIABILITIES

Credit Commitments and Guarantees

In the normal course of business, the Company enters into a variety of financial instruments with off-balance sheet risk to meet the financing needs of its customers and to conduct lending activities, including commitments to extend credit and standby and commercial letters of credit. These instruments involve elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Statements of Financial Condition.

⁽¹⁾  Other commitments includes installment and overdraft protection program commitments.

⁽²⁾  Included in other liabilities in the Consolidated Statements of Financial Condition.

Commitments to extend credit are agreements to lend funds to a customer, subject to contractual terms and covenants. Commitments generally have fixed expiration dates or other termination clauses, variable interest rates, and fee requirements, when applicable. Since many of the commitments are expected to expire without being drawn, the total commitment amounts do not necessarily represent future cash flow requirements.

In the event of a customer's non-performance, the Company's credit loss exposure is equal to the contractual amount of the commitments. The credit risk is essentially the same as extending loans to customers. The Company uses the same credit policies for credit commitments as its loans and minimizes exposure to credit loss through various collateral requirements.

Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby letters of credit generally are contingent on the failure of the customer to perform according to the terms of the contract with the third party and are often issued in favor of a municipality where construction is taking place to ensure the borrower adequately completes the construction.

The maximum potential future payments guaranteed by the Company under standby letters of credit arrangements are equal to the contractual amount of the commitment. If a commitment is funded, the Company may seek recourse through the liquidation of the underlying collateral, including real estate, production plants and property, marketable securities, or receipt of cash.

As a result of the sale of certain 1-4 family mortgage loans, the Company is contractually obligated to repurchase any non-performing loans or loans that do not meet underwriting requirements at recorded value. In accordance with the sales agreements, there is no limitation to the maximum potential future payments or expiration of the Company's recourse obligation. There were no material loan repurchases during the quarters ended March 31, 2016 and 2015.

Legal Proceedings

In the ordinary course of business, there were certain legal proceedings pending against the Company and its subsidiaries at March 31, 2016. While the outcome of any legal proceeding is inherently uncertain, based on information currently available, the Company's management does not expect that any liabilities arising from pending legal matters will have a material adverse effect on the Company's financial position, results of operations, or liquidity.

Fair Value Disclosures [Abstract]

Fair Value

FAIR VALUE

Fair value represents the amount expected to be received to sell an asset or paid to transfer a liability in its principal or most advantageous market in an orderly transaction between market participants at the measurement date. In accordance with fair value accounting guidance, the Company measures, records, and reports various types of assets and liabilities at fair value on either a recurring or non-recurring basis in the Consolidated Statements of Financial Condition. Those assets and liabilities are presented below in the sections titled "Assets and Liabilities Required to be Measured at Fair Value on a Recurring Basis" and "Assets and Liabilities Required to be Measured at Fair Value on a Non-Recurring Basis."

Other assets and liabilities are not required to be measured at fair value in the Consolidated Statements of Financial Condition, but must be disclosed at fair value. See the "Fair Value Measurements of Other Financial Instruments" section of this note. Any aggregation of the estimated fair values presented in this note does not represent the value of the Company.

Depending on the nature of the asset or liability, the Company uses various valuation methodologies and assumptions to estimate fair value. GAAP provides a three-tiered fair value hierarchy based on the inputs used to measure fair value. The hierarchy is defined as follows:

• Level 1 - Quoted prices in active markets for identical assets or liabilities.

• Level 2 - Observable inputs other than level 1 prices, such as quoted prices for similar instruments, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

• Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These inputs require significant management judgment or estimation, some of which use model-based techniques and may be internally developed.

Assets and liabilities are assigned to a level within the fair value hierarchy based on the lowest level of significant input used to measure fair value. Assets and liabilities may change levels within the fair value hierarchy due to market conditions or other circumstances. Those transfers are recognized on the date of the event that prompted the transfer. There were no transfers of assets or liabilities between levels of the fair value hierarchy during the periods presented.

Assets and Liabilities Required to be Measured at Fair Value on a Recurring Basis

The following table provides the fair value for assets and liabilities required to be measured at fair value on a recurring basis in the Consolidated Statements of Financial Condition by level in the fair value hierarchy.

The following sections describe the specific valuation techniques and inputs used to measure financial assets and liabilities at fair value.

Trading Securities

The Company's trading securities consist of diversified investment securities held in a grantor trust and are invested in money market and mutual funds. The fair value of these money market and mutual funds is based on quoted market prices in active exchange markets and is classified in level 1 of the fair value hierarchy.

Securities Available-for-Sale

The Company's securities available-for-sale are primarily fixed income instruments that are not quoted on an exchange, but may be traded in active markets. The fair values for these securities are based on quoted prices in active markets or market prices for similar securities obtained from external pricing services or dealer market participants and are classified in level 2 of the fair value hierarchy. The fair value of U.S. treasury securities is based on quoted market prices in active exchange markets and is classified in level 1 of the fair value hierarchy. Quarterly, the Company evaluates the methodologies used by its external pricing services to estimate the fair value of these securities to determine whether the valuations represent an exit price in the Company's principal markets.

CDOs are classified in level 3 of the fair value hierarchy. The Company estimates the fair values for each CDO using discounted cash flow analyses with the assistance of a structured credit valuation firm. This methodology is based on credit analysis and historical financial data for each of the issuers underlying the CDOs (the "Issuers"). These estimates are highly subjective and sensitive to several significant, unobservable inputs. The cash flows for each Issuer are then discounted to present values using LIBOR plus an adjustment to reflect the impact of market factors. Finally, the discounted cash flows for each Issuer are aggregated to derive the estimated fair value for the specific CDO.

The following table presents the ranges of significant, unobservable inputs calculated using the weighted average of the Issuers used by the Company as of March 31, 2016 and December 31, 2015.

Significant Unobservable Inputs Used in the Valuation of CDOs

	As of
	March 31, 2016				December 31, 2015
Probability of prepayment	1.8	%	-	15.1%	1.8	%	-	15.1%
Probability of default	18.6	%	-	49.7%	19.1	%	-	32.6%
Loss given default	92.8	%	-	98.4%	93.8	%	-	97.1%
Probability of deferral cure	15.2	%	-	63.5%	15.2	%	-	63.1%

Most Issuers have the right to prepay the securities on the fifth anniversary of issuance and under other limited circumstances. To estimate prepayments, a credit analysis of each Issuer is performed to estimate its ability and likelihood to fund a prepayment. If a prepayment occurs, the Company receives cash equal to the par value for the portion of the CDO associated with that Issuer.

The likelihood that an Issuer who is currently deferring payment on the securities will pay all deferred amounts and remain current thereafter is based on an analysis of the Issuer's asset quality, leverage ratios, and other measures of financial viability.

The impact of changes in these key inputs could result in a significantly higher or lower fair value measurement for each CDO. The timing of the default, the magnitude of the default, and the timing and magnitude of the cure probability are directly interrelated. Defaults that occur sooner and/or are greater than anticipated have a negative impact on the valuation. In addition, a high cure probability assumption has a positive effect on the fair value, and, if a cure event takes place sooner than anticipated, the impact on the valuation is also favorable.

Management monitors the valuation results of each CDO on a semi-annual basis, which includes an analysis of historical pricing trends for these types of securities, overall economic conditions (such as tracking LIBOR curves), and the performance of the Issuers' industries. Annually, management validates significant assumptions by reviewing detailed back-testing performed by the structured credit valuation firm.

A rollforward of the carrying value of CDOs for the quarters ended March 31, 2016 and 2015 is presented in the following table.

Carrying Value of CDOs

Paydowns	14			(146		)
Ending balance	$	30,757		$	33,928

⁽¹⁾  Included in unrealized holding gains in the Consolidated Statements of Comprehensive Income.

MSRs

The Company services loans for others totaling $600.8 million as of March 31, 2016 and $242.9 million as of December 31, 2015. These loans are owned by third parties and are not included in the Consolidated Statements of Financial Condition. As of March 31, 2016, loans serviced for others includes approximately $350.0 million of loans, the servicing of which transitioned from NI Bancshares to the Company as a result of the NI Bancshares acquisition, and resulted in an additional $3.1 million of MSRs. Additional information regarding the NI Bancshares transaction is presented in Note 3, "Acquisitions."

The Company determines the fair value of MSRs by estimating the present value of expected future cash flows associated with the mortgage loans being serviced and classifies them in level 3 of the fair value hierarchy. The following table presents the ranges of significant, unobservable inputs used by the Company to determine the fair value of MSRs as of March 31, 2016.

Significant Unobservable Inputs Used in the Valuation of MSRs

	As of
	March 31, 2016				December 31, 2015
Prepayment speed	10.9	%	-	23.0%	10.1	%	-	20.9%
Maturity (months)	4		-	79	6		-	86
Discount rate	9.5	%	-	13.0%	9.5	%	-	13.0%

The impact of changes in these key inputs could result in a significantly higher or lower fair value measurement for MSRs. Significant increases in expected prepayment speeds and discount rates have negative impacts on the valuation. Higher maturity assumptions have a favorable effect on the estimated fair value.

A rollforward of the carrying value of MSRs for the quarters ended March 31, 2016 and 2015 is presented in the following table.

Carrying Value of MSRs

⁽²⁾  Primarily represents changes in expected future cash flows due to payoffs and paydowns.

Derivative Assets and Derivative Liabilities

The Company enters into interest rate swaps and derivative transactions with commercial customers. These derivative transactions are executed in the dealer market, and pricing is based on market quotes obtained from the counterparties. The market quotes were developed using market observable inputs, which primarily include LIBOR. Therefore, derivatives are classified in level 2 of the fair value hierarchy. For its derivative assets and liabilities, the Company also considers non-performance risk, including the likelihood of default by itself and its counterparties, when evaluating whether the market quotes from the counterparty are representative of an exit price.

Assets and Liabilities Required to be Measured at Fair Value on a Non-Recurring Basis

The following table provides the fair value for each class of assets and liabilities required to be measured at fair value on a non-recurring basis in the Consolidated Statements of Financial Condition by level in the fair value hierarchy.

Non-Recurring Fair Value Measurements

⁽³⁾  Included in other assets in the Consolidated Statements of Financial Condition.

⁽⁴⁾  Included in premises, furniture, and equipment in the Consolidated Statements of Financial Condition.

Collateral-Dependent Impaired Loans

Certain collateral-dependent impaired loans are subject to fair value adjustments to reflect the difference between the carrying value of the loan and the value of the underlying collateral. The fair values of collateral-dependent impaired loans are primarily determined by current appraised values of the underlying collateral. Based on the age and/or type, appraisals may be adjusted in the range of 0% to 15%. In certain cases, an internal valuation may be used when the underlying collateral is located in areas where comparable sales data is limited or unavailable. Accordingly, collateral-dependent impaired loans are classified in level 3 of the fair value hierarchy.

Collateral-dependent impaired loans for which the fair value is greater than the recorded investment are not measured at fair value in the Consolidated Statements of Financial Condition and are not included in this disclosure.

OREO

The fair value of OREO is measured using the current appraised value of the properties. In certain circumstances, a current appraisal may not be available or may not represent an accurate measurement of the property's fair value due to outdated market information or other factors. In these cases, the fair value is determined based on the lower of the (i) most recent appraised value, (ii) broker price opinion, (iii) current listing price, or (iv) signed sales contract. Given these valuation methods, OREO is classified in level 3 of the fair value hierarchy.

Loans Held-for-Sale

As of March 31, 2016, loans held-for-sale consists of 1-4 family mortgage loans, which were originated with the intent to sell. These loans were recorded in the held-for-sale category at the contract price and, accordingly, are classified in level 3 of the fair value hierarchy. As of December 31, 2015, loans held-for-sale consists of 1-4 family mortgage loans, which were originated with the intent to sell, and a commercial real estate loan.

Assets Held-for-Sale

Assets held-for-sale as of March 31, 2016 and December 31, 2015 consists of twelve former branches that are no longer in operation and seven parcels of land previously purchased for expansion. These properties are being actively marketed and were transferred into the held-for-sale category at the lower of their fair value, as determined by a current appraisal. Based on these valuation methods, they are classified in level 3 of the fair value hierarchy.

Financial Instruments Not Required to be Measured at Fair Value

For certain financial instruments that are not required to be measured at fair value in the Consolidated Statements of Financial Condition, the Company must disclose the estimated fair values and the level within the fair value hierarchy as shown in the following table.

Accrued interest payable	2	5,446		5,446		2,175		2,175

Management uses various methodologies and assumptions to determine the estimated fair values of the financial instruments in the table above. The fair value estimates are made at a discrete point in time based on relevant market information and consider management's judgments regarding future expected economic conditions, loss experience, and specific risk characteristics of the financial instruments.

Short-Term Financial Assets and Liabilities - For financial instruments with a shorter-term or with no stated maturity, prevailing market rates, and limited credit risk, the carrying amounts approximate fair value. Those financial instruments include cash and due from banks, interest-bearing deposits in other banks, accrued interest receivable, and accrued interest payable.

Securities Held-to-Maturity - The fair value of securities held-to-maturity is estimated using the present value of expected future cash flows of the remaining maturities of the securities.

FHLB and FRB Stock - The carrying amounts approximate fair value as the stock is non-marketable.

Loans - Loans includes the FDIC indemnification asset and net loans, which consists of loans held-for-investment, acquired loans, covered loans, and the allowance for loan losses. The fair value of loans is estimated using the present value of the expected future cash flows of the remaining maturities of the loans. Prepayment assumptions that consider the Company's historical experience and current economic and lending conditions were included. The discount rate was based on the LIBOR yield curve with adjustments for liquidity and credit risk inherent in the loans.

The fair value of the covered loan portfolio is determined by discounting the expected future cash flows at a market interest rate, which is derived from LIBOR swap rates over the life of those loans. The expected future cash flows are derived from the contractual terms of the covered loans, net of any projected credit losses. For valuation purposes, these loans are placed into groups with similar characteristics and risk factors, where appropriate. The timing and amount of credit losses for each group are estimated using historical default and loss experience, current collateral valuations, borrower credit scores, and internal risk ratings. For individually significant loans or credit relationships, the estimated fair value is determined by a specific loan level review utilizing appraised values for collateral and projections of the timing and amount of expected future cash flows.

Investment in BOLI - The fair value of BOLI approximates the carrying amount as both are based on each policy's respective cash surrender value ("CSV"), which is the amount the Company would receive from liquidation of these investments. The CSV is derived from monthly reports provided by the managing brokers and is determined using the Company's initial insurance premium and earnings of the underlying assets, offset by management fees.

Other Interest-Earning Assets - The fair value of other interest-earning assets is estimated using the present value of the expected future cash flows of the remaining maturities of the assets.

Deposits - The fair values disclosed for demand deposits, savings deposits, NOW accounts, and money market deposits are equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The fair value for fixed-rate time deposits was estimated using the expected future cash flows discounted based on the LIBOR yield curve, plus or minus the spread associated with current pricing.

Borrowed Funds- The fair value of FHLB advances is estimated by discounting the agreements based on maturities using the rates currently offered for FHLB advances of similar remaining maturities adjusted for prepayment penalties that would be incurred if the borrowings were paid off on the measurement date. The carrying amounts of securities sold under agreements to repurchase approximate their fair value due to their short-term nature.

Senior and Subordinated Debt - The fair value of senior and subordinated debt is determined using quoted market prices.

Commitments to Extend Credit and Letters of Credit - The Company estimated the fair value of lending commitments outstanding to be immaterial based on (i) the limited interest rate exposure of the commitments outstanding due to their variable nature, (ii) the short-term nature of the commitment periods, (iii) termination clauses provided in the agreements, and (iv) the market rate of fees charged.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2016

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation – The accompanying unaudited condensed consolidated interim financial statements ("consolidated financial statements") of First Midwest Bancorp, Inc. (the "Company"), a Delaware corporation, were prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") for quarterly reports on Form 10-Q and reflect all adjustments that management deems necessary for the fair presentation of the financial position and results of operations for the periods presented. The results of operations for the quarter ended March 31, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016.

The accounting and reporting policies of the Company and its subsidiaries conform to U.S. generally accepted accounting principles ("GAAP") and general practices within the banking industry. The accompanying consolidated financial statements do not include certain information and note disclosures required by GAAP for complete annual financial statements. Therefore, these financial statements should be read in conjunction with the Company's 2015 Annual Report on Form 10-K ("2015 10-K"). The Company uses the accrual basis of accounting for financial reporting purposes.

Reclassification

Certain reclassifications were made to prior year amounts to conform to the current year presentation.

Use of Estimates

Use of Estimates – The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Although these estimates and assumptions are based on the best available information, actual results could differ from those estimates.

Principles of Consolidation

Principles of Consolidation – The accompanying consolidated financial statements include the financial position and results of operations of the Company and its subsidiaries after elimination of all significant intercompany accounts and transactions. Assets held in a fiduciary or agency capacity are not assets of the Company or its subsidiaries and are not included in the consolidated financial statements.

Business Combinations

Business Combinations – Business combinations are accounted for under the acquisition method of accounting. Assets acquired and liabilities assumed are recorded at their estimated fair values as of the date of acquisition, with any excess of the purchase price of the acquisition over the fair value of the identifiable net tangible and intangible assets acquired recorded as goodwill. Alternatively, a gain is recorded if the fair value of assets purchased exceeds the fair value of liabilities assumed and consideration paid. The results of operations of the acquired business are included in the Condensed Consolidated Statements of Income from the effective date of the acquisition.

Loans

Loans – Loans held-for-investment are loans that the Company intends to hold until they are paid in full and are carried at the principal amount outstanding, including certain net deferred loan origination fees. Loan origination fees, commitment fees, and certain direct loan origination costs are deferred, and the net amount is amortized as a yield adjustment over the contractual life of the related loans or commitments and included in interest income. Fees related to standby letters of credit are amortized into fee income over the contractual life of the commitment. Other credit-related fees are recognized as fee income when earned. The Company's net investment in direct financing leases is included in loans and consists of future minimum lease payments and estimated residual values, net of unearned income. Interest income on loans is accrued based on principal amounts outstanding. Loans held-for-sale are carried at the lower of aggregate cost or fair value and included in other assets in the Consolidated Statements of Financial Condition.

Acquired and Covered Loans

Acquired and Covered Loans – Covered loans consists of loans acquired by the Company in Federal Deposit Insurance Corporation ("FDIC")-assisted transactions, which are covered by loss share agreements with the FDIC (the "FDIC Agreements"), under which the FDIC reimburses the Company for the majority of the losses and eligible expenses related to these assets during the coverage period. Acquired loans consist of all other loans that were acquired in business combinations that are not covered by FDIC Agreements. Covered loans and acquired loans are included within loans held-for-investment.

Acquired and covered loans are separated into (i) non-purchased credit impaired ("Non-PCI") and (ii) purchased credit impaired ("PCI") loans. Non-PCI loans include loans that did not have evidence of credit deterioration since origination at the acquisition date. PCI loans include loans that had evidence of credit deterioration since origination and for which it was probable at acquisition that the Company would not collect all contractually required principal and interest payments. Evidence of credit deterioration was evaluated using various indicators, such as past due and non-accrual status. Leases and revolving loans do not qualify to be accounted for as PCI loans and are accounted for as Non-PCI loans.

The acquisition adjustment related to Non-PCI loans is amortized into interest income over the contractual life of the related loans. If an acquired non-PCI loan is renewed subsequent to the acquisition date, any remaining acquisition adjustment is accreted into interest income and the loan is considered a new loan that is no longer classified as an acquired loan.

PCI loans are accounted for based on estimates of expected future cash flows. To estimate the fair value, the Company generally aggregates purchased consumer loans and certain smaller balance commercial loans into pools of loans with common risk characteristics, such as delinquency status, credit score, and internal risk ratings. The fair values of larger balance commercial loans are estimated on an individual basis. Expected future cash flows in excess of the fair value of loans at the purchase date ("accretable yield") are recorded as interest income over the life of the loans if the timing and amount of the expected future cash flows can be reasonably estimated. The non-accretable yield represents the difference between contractually required payments and the expected future cash flows determined at acquisition. Subsequent increases in expected future cash flows are offset against the allowance for credit losses to the extent an allowance has been established or otherwise recognized as interest income prospectively. The present value of any decreases in expected future cash flows is recognized by recording a charge-off through the allowance for loan losses or providing an allowance for loan losses.

90-Days Past Due Loans

90-Days Past Due Loans –The Company's accrual of interest on loans is discontinued at the time the loan is 90 days past due unless the credit is sufficiently collateralized and in the process of renewal or collection.

Non-accrual Loans

Non-accrual Loans– Generally, corporate loans are placed on non-accrual status (i) when either principal or interest payments become 90 days or more past due unless the credit is sufficiently collateralized and in the process of renewal or collection, or (ii) when an individual analysis of a borrower's creditworthiness warrants a downgrade to non-accrual regardless of past due status. When a loan is placed on non-accrual status, unpaid interest credited to income in the current year is reversed, and unpaid interest accrued in prior years is charged against the allowance for loan losses. After the loan is placed on non-accrual, all debt service payments are applied to the principal on the loan. Future interest income may only be recorded on a cash basis after recovery of principal is reasonably assured. Non-accrual loans are returned to accrual status when the financial position of the borrower and other relevant factors indicate that the Company will collect all principal and interest.

Commercial loans and loans secured by real estate are charged-off when deemed uncollectible. A loss is recorded if the net realizable value of the underlying collateral is less than the outstanding principal and interest. Consumer loans that are not secured by real estate are subject to mandatory charge-off at a specified delinquency date and are usually not classified as non-accrual prior to being charged-off. Closed-end consumer loans, which include installment, automobile, and single payment loans, are usually charged-off no later than the end of the month in which the loan becomes 120 days past due.

PCI loans are generally considered accruing loans unless reasonable estimates of the timing and amount of expected future cash flows cannot be determined. Loans without reasonable future cash flow estimates are classified as non-accrual loans, and interest income is not recognized on those loans until the timing and amount of the expected future cash flows can be reasonably determined.

Troubled Debt Restructurings (“TDRs”)

Troubled Debt Restructurings ("TDRs") – A restructuring is considered a TDR when (i) the borrower is experiencing financial difficulties, and (ii) the creditor grants a concession, such as forgiveness of principal, reduction of the interest rate, changes in payments, or extension of the maturity date. Loans are not classified as TDRs when the modification is short-term or results in an insignificant delay in payments. The Company's TDRs are determined on a case-by-case basis.

The Company does not accrue interest on a TDR unless it believes collection of all principal and interest under the modified terms is reasonably assured. For a TDR to begin accruing interest, the borrower must demonstrate some level of past performance and the future capacity to perform under the modified terms. Generally, six months of consecutive payment performance under the restructured terms is required before a TDR is returned to accrual status. However, the period could vary depending on the individual facts and circumstances of the loan. An evaluation of the borrower's current creditworthiness is used to assess the borrower's capacity to repay the loan under the modified terms. This evaluation includes an estimate of expected future cash flows, evidence of strong financial position, and estimates of the value of collateral, if applicable. For TDRs to be removed from TDR status in the calendar year after the restructuring, the loans must (i) have an interest rate and terms that reflect market conditions at the time of restructuring, and (ii) be in compliance with the modified terms. If the loan was restructured at below market rates and terms, it continues to be separately reported as restructured until it is paid in full or charged-off.

Impaired Loans

Impaired Loans – Impaired loans consist of corporate non-accrual loans and TDRs. A loan is considered impaired when it is probable that the Company will not collect all contractual principal and interest. With the exception of accruing TDRs, impaired loans are classified as non-accrual and are exclusive of smaller homogeneous loans, such as home equity, 1-4 family mortgages, and installment loans. Impaired loans with balances under a specified threshold are not individually evaluated for impairment. For all other impaired loans, impairment is measured by comparing the estimated value of the loan to the recorded book value. The value of collateral-dependent loans is based on the fair value of the underlying collateral, less costs to sell. The value of other loans is measured using the present value of expected future cash flows discounted at the loan's initial effective interest rate.

Allowance for Credit Losses

Allowance for Credit Losses – The allowance for credit losses is comprised of the allowance for loan losses and the reserve for unfunded commitments, and is maintained by management at a level believed adequate to absorb estimated losses inherent in the existing loan portfolio. Determination of the allowance for credit losses is subjective since it requires significant estimates and management judgment, including the amounts and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans, consideration of current economic trends, and other factors.

Loans deemed to be uncollectible are charged-off against the allowance for loan losses, while recoveries of amounts previously charged-off are credited to the allowance for loan losses. Additions to the allowance for loan losses are charged to expense through the provision for loan losses. The amount of provision depends on a number of factors, including net charge-off levels, loan growth, changes in the composition of the loan portfolio, and the Company's assessment of the allowance for loan losses based on the methodology discussed below.

Allowance for Loan Losses– The allowance for loan losses consists of (i) specific reserves for individual loans where the recorded investment exceeds the value, (ii) an allowance based on a loss migration analysis that uses historical credit loss experience for each loan category, and (iii) an allowance based on other internal and external qualitative factors.

The specific reserves component of the allowance for loan losses is based on a periodic analysis of impaired loans exceeding a fixed dollar amount. If the value of an impaired loan is less than the recorded book value, the Company either establishes a valuation allowance (i.e., a specific reserve) equal to the excess of the book value over the value of the loan as a component of the allowance for loan losses or charges off the amount if it is a confirmed loss.

The general reserve component is based on a loss migration analysis, which examines actual loss experience by loan category for a rolling 8-quarter period and the related internal risk rating for corporate loans. The loss migration analysis is updated quarterly primarily using actual loss experience. This component is then adjusted based on management's consideration of many internal and external qualitative factors, including:

• Changes in the composition of the loan portfolio, trends in the volume of loans, and trends in delinquent and non-accrual loans that could indicate that historical trends do not reflect current conditions.

• Changes in credit policies and procedures, such as underwriting standards and collection, charge-off, and recovery practices.

• Changes in the experience, ability, and depth of credit management and other relevant staff.

• Changes in the quality of the Company's loan review system and Board of Directors oversight.

• The effect of any concentration of credit and changes in the level of concentrations, such as loan type or risk rating.

• Changes in the value of the underlying collateral for collateral-dependent loans.

• Changes in the national and local economy that affect the collectability of various segments of the portfolio.

• The effect of other external factors, such as competition and legal and regulatory requirements, on the Company's loan portfolio.

The allowance for loan losses also consists of an allowance on acquired and covered Non-PCI and PCI loans. No allowance for loan losses is recorded on acquired loans at the acquisition date. Subsequent to the acquisition date, an allowance for credit losses is established as necessary to reflect credit deterioration. The acquired Non-PCI allowance is based on management's evaluation of the acquired Non-PCI loan portfolio giving consideration to the current portfolio balance including the remaining acquisition adjustments, maturity dates, and overall credit quality. The allowance for covered Non-PCI loans is calculated in the same manner as the general reserve component based on a loss migration analysis as discussed above. The acquired and covered PCI allowance reflects the difference between the carrying value and the discounted expected future cash flows of the acquired and covered PCI loans. On a periodic basis, the adequacy of this allowance is determined through a re-estimation of expected future cash flows on all the outstanding acquired and covered PCI loans using either a probability of default/loss given default ("PD/LGD") methodology or a specific review methodology. The PD/LGD model is a loss model that estimates expected future cash flows using a probability of default curve and loss given default estimates. Acquired Non-PCI loans that have renewed subsequent to the respective acquisition dates are no longer classified as acquired loans. Instead, they are included with our general loan population and allocated an allowance based on a loss migration analysis.

Reserve for Unfunded Commitments– The Company also maintains a reserve for unfunded commitments, including letters of credit, for the risk of loss inherent in these arrangements. The reserve for unfunded commitments is estimated using the loss migration analysis from the allowance for loan losses, adjusted for probabilities of future funding requirements. The reserve for unfunded commitments is included in other liabilities in the Consolidated Statements of Financial Condition.

The establishment of the allowance for credit losses involves a high degree of judgment given the difficulty of assessing the factors impacting loan repayment and estimating the timing and amount of losses. While management utilizes its best judgment and information available, the adequacy of the allowance for credit losses depends on a variety of factors beyond the Company's control, including the performance of its loan portfolio, the economy, changes in interest rates and property values, and the interpretation of loan risk classifications by regulatory authorities.

Derivative Financial Instruments

Derivative Financial Instruments – To provide derivative products to customers and in the ordinary course of business, the Company enters into derivative transactions as part of its overall interest rate risk management strategy to minimize significant unplanned fluctuations in earnings and expected future cash flows caused by interest rate volatility. All derivative instruments are recorded at fair value as either other assets or other liabilities in the Consolidated Statements of Financial Condition. Subsequent changes in a derivative's fair value are recognized in earnings unless specific hedge accounting criteria are met.

On the date the Company enters into a derivative contract, the derivative is designated as a fair value hedge, a cash flow hedge, or a non-hedge derivative instrument. Fair value hedges are designed to mitigate exposure to changes in the fair value of an asset or liability attributable to a particular risk, such as interest rate risk. Cash flow hedges are designed to mitigate exposure to variability in expected future cash flows to be received or paid related to an asset, liability, or other type of forecasted transaction. The Company formally documents all relationships between hedging instruments and hedged items, including its risk management objective and strategy at inception.

At the hedge's inception and quarterly thereafter, a formal assessment is performed to determine the effectiveness of the derivative in offsetting changes in the fair values or expected future cash flows of the hedged items in the current period and prospectively. If a derivative instrument designated as a hedge is terminated or ceases to be highly effective, hedge accounting is discontinued prospectively, and the gain or loss is amortized into earnings. For fair value hedges, the gain or loss is amortized over the remaining life of the hedged asset or liability. For cash flow hedges, the gain or loss is amortized over the same period that the forecasted hedged transactions impact earnings. If the hedged item is disposed of, any fair value adjustments are included in the gain or loss from the disposition of the hedged item. If the forecasted transaction is no longer probable, the gain or loss is included in earnings immediately.

For fair value hedges, changes in the fair value of the derivative instruments, as well as changes in the fair value of the hedged item, are recognized in earnings. For cash flow hedges, the effective portion of the change in fair value of the derivative instrument is reported as a component of accumulated other comprehensive loss and is reclassified to earnings when the hedged transaction is reflected in earnings.

Ineffectiveness is calculated based on the change in fair value of the hedged item compared with the change in fair value of the hedging instrument. For all types of hedges, any ineffectiveness in the hedging relationship is recognized in earnings during the period the ineffectiveness occurs.

Recent Accounting Pronouncements

RECENT ACCOUNTING PRONOUNCEMENTS

Adopted Accounting Pronouncements

Amendments to Consolidation Analysis: In February 2015, the Financial Accounting Standards Board ("FASB") issued guidance that updates current accounting for the consolidation of certain legal entities. This guidance modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs") or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, affects the consolidation analysis of reporting entities that are involved with VIEs, and provides certain exceptions from consolidation guidance for certain reporting entities. This guidance is effective for annual and interim periods beginning after December 15, 2015. The adoption of this guidance on January 1, 2016 did not materially impact the Company's financial condition, results of operations, or liquidity.

Simplifying the Presentation of Debt Issuance Costs: In April of 2015, the FASB issued guidance to clarify the presentation of debt issuance costs within the balance sheet. Additionally, the guidance requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this amendment. The guidance is effective for annual and interim periods beginning after December 15, 2015. The adoption of this guidance on January 1, 2016 did not materially impact the Company's financial condition, results of operations, or liquidity.

Accounting Pronouncements Pending Adoption

Revenue from Contracts with Customers: In May of 2014, the FASB issued guidance that requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In March of 2016, the FASB issued an amendment to this guidance to clarify the implementation of guidance on principal versus agent consideration. An additional amendment to clarify the implementation guidance on the identification of performance obligations and licensing was issued in April of 2016.

The guidance was initially effective for annual and interim reporting periods beginning on or after December 15, 2016. In August of 2015, the FASB issued guidance that defers the effective date by one year. The deferral causes the guidance to be effective for annual and interim reporting periods beginning on or after December 15, 2017, and must be applied either retrospectively or using the modified retrospective approach. Early adoption is permitted, but not before the original effective date. Management is evaluating the new guidance, but does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern: In August of 2014, the FASB issued guidance that requires management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued. The guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Amendments to Guidance on Classifying and Measuring Financial Instruments: In January of 2016, the FASB issued guidance that will require entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value. Any changes in fair value will be recognized in net income unless the investments qualify for a new practicability exception. This guidance also requires entities to recognize changes in instrument-specific credit risk related to financial liabilities measured under the fair value option in other comprehensive income. No changes were made to the guidance for classifying and measuring investments in debt securities and loans. This guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Leases: In February of 2016, the FASB issued guidance to increase transparency and comparability across entities for leasing arrangements. This guidance requires lessees to recognized assets and liabilities for most leases. For lessors, this guidance modifies the lease classification criteria and the accounting for sales-type and direct financing leases. In addition, this guidance clarifies criteria for the determination of whether a contract is or contains a lease. This guidance is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted. Management is evaluating the new guidance and the impact to the Company's financial condition, results of operations, and liquidity.

Contingent Put and Call Options in Debt Instruments: In March of 2016, the FASB issued final guidance clarifying the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. Entities are required to apply the guidance to existing debt instruments (or hybrid financial instruments that are determined to have a debt host) using a modified retrospective transition method as of the period of adoption. This guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Equity Method Accounting: In March of 2016, the FASB issued final guidance to simplify the equity method of accounting. The guidance eliminates the requirement to retrospectively apply equity method accounting in previous periods when an investor initially obtains significant influence over an investee. This guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Accounting for Employee Share-based Payments: In March of 2016, the FASB issued guidance to simplify the accounting for employee share-based payment transactions. The guidance requires entities to recognize the income tax effects of awards in the income statement when the awards vest or are settled. In addition, the guidance allows entities to repurchase more of an employee's shares than it can under current guidance for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. This guidance is effective for annual and interim reporting periods beginning on or after December 15, 2016. Early adoption is permitted. Management is evaluating the new guidance, but does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

⁽²⁾  Loans categorized as substandard exhibit well-defined weaknesses that may jeopardize the liquidation of the debt. These loans continue to accrue interest because they are well secured and collection of principal and interest is expected within a reasonable time.

⁽³⁾  Loans categorized as non-accrual exhibit well-defined weaknesses that may jeopardize the liquidation of the debt or result in a loss if the deficiencies are not corrected.

⁽⁴⁾  Total special mention and substandard loans includes accruing TDRs of $854,000 as of March 31, 2016 and $862,000 as of December 31, 2015.
