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 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, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.

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 quarterly statements do not include certain information and footnote disclosures required by GAAP for complete annual financial statements. Therefore, these financial statements should be read in conjunction with the Company’s 2013 Annual Report on Form 10-K (“2013 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.

Principles of Consolidation – The accompanying condensed 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 condensed consolidated financial statements.

Use of Estimates – The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed 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.

The accounting policies related to loans, the allowance for credit losses, the FDIC indemnification asset, and derivative financial instruments are presented below. For a summary of all other significant accounting policies, please refer to Note 1, “Summary of Significant Accounting Policies,” in the Company’s 2013 10-K.

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. Interest income on loans is accrued based on principal amounts outstanding. 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. 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.

Purchased Impaired Loans – Purchased impaired loans include acquired loans that had evidence of credit deterioration since origination and 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. Other key considerations included past performance of the failed institutions' credit underwriting standards, completeness and accuracy of credit files, maintenance of risk ratings, and age of appraisals. Lease and revolving loans do not qualify to be accounted for as purchased impaired loans. Purchased impaired loans are recorded at fair value on the acquisition date, and are accounted for prospectively based on estimates of expected cash flows. No allowance for credit losses is recorded on these loans at the acquisition date. 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 rating. 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 future cash flows can be reasonably estimated. The non-accretable yield represents the difference between contractually required payments and the cash flows expected to be collected at acquisition.

Subsequent increases in cash flows are recognized as interest income prospectively. The present value of any decreases in expected cash flows is recognized by recording a charge-off through the allowance for loan and covered loan losses or establishing an allowance for loan and covered loan losses.

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 loan is sufficiently collateralized such that full repayment of both principal and interest is expected and is in the process of collection within a reasonable period 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.

Purchased impaired loans are generally considered accruing loans unless reasonable estimates of the timing and amount of future cash flows cannot be determined. Loans without reasonable 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 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 both 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 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. Purchased impaired loans are not reported as impaired loans provided that estimates of the timing and amount of future cash flows can be reasonably determined.

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.

Allowance for Credit Losses – The allowance for credit losses is comprised of the allowance for loan losses, the allowance for covered 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 and covered loan losses, while recoveries of amounts previously charged-off are credited to the allowance for loan and covered loan losses. Additions to the allowance for loan and covered loan losses are charged to expense through the provision for loan and covered 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 and covered 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) and 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 using actual loss experience. This component is then adjusted based on management’s consideration of many internal and external qualitative factors, including:

Allowance for Covered Loan Losses – The Company’s allowance for covered loan losses reflects the difference between the carrying value and the discounted present value of the estimated cash flows of the covered purchased impaired loans. On a periodic basis, the adequacy of this allowance is determined through a re-estimation of cash flows on all of the outstanding covered purchased impaired loans using either a probability of default/loss given default (“PD/LGD”) methodology or a specific review methodology. The PD/LGD model is an expected loss model that estimates future cash flows using a probability of default curve and loss given default estimates.

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.

FDIC Indemnification Asset – The majority of loans and OREO acquired through FDIC-assisted transactions 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. The FDIC indemnification asset represents the present value of future expected reimbursements from the FDIC. Since the indemnified items are covered loans and covered OREO, which are initially measured at fair value, the FDIC indemnification asset is also initially measured at fair value by discounting the cash flows expected to be received from the FDIC. These cash flows are estimated by multiplying estimated losses on purchased impaired loans and OREO by the reimbursement rates in the FDIC Agreements.

The balance of the FDIC indemnification asset is adjusted periodically to reflect changes in estimated cash flows. Decreases in estimated reimbursements from the FDIC are recorded prospectively through amortization and increases in estimated reimbursements from the FDIC are recognized by an increase in the carrying value of the indemnification asset. Payments from the FDIC for reimbursement of losses result in a reduction of the FDIC indemnification asset.

Derivative Financial Instruments – 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 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 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 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 effective 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

Income Taxes: In January of 2014, the FASB issued guidance that requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date or, if the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The guidance is effective for annual and interim reporting periods beginning on or after December 15, 2013, and must be applied prospectively. The adoption of this guidance on January 1, 2014 did not impact the Company's financial condition, results of operations, or liquidity.

Receivables - Troubled Debt Restructurings by Creditors: In January of 2014, the FASB issued guidance to clarify when an in substance repossession or foreclosure occurs and an entity is considered to have received physical possession of the residential real estate property such that a loan receivable should be derecognized and the real estate property recognized. Additionally, the guidance requires interim and annual disclosure of the amount of foreclosed residential real estate property held by the entity and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The guidance is effective for annual and interim periods beginning after December 15, 2014 and can be applied retrospectively or prospectively. Management does not expect the adoption of this guidance to materially impact the Company's financial condition, results of operations, or liquidity.

3.  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 positive 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 that allow plan participants to direct amounts into a variety of securities, including Company stock. Net trading gains represent changes in the fair value of the trading securities portfolio and are included in other noninterest income in the Condensed Consolidated Statements of Income.

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.

The carrying value of securities available-for-sale that were pledged to secure deposits or for other purposes as permitted or required by law totaled $675.5 million at March 31, 2014 and $755.3 million at December 31, 2013. No securities held-to-maturity were pledged as of March 31, 2014 or December 31, 2013.

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. The following table presents net realized gains on securities.

The non-cash impairment charges in the table above relate to OTTI charges on certain CMOs. 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 (loss).

The following table presents the cumulative amount of OTTI on CDOs related to credit deterioration recognized by year in earnings.

In deriving the credit component of the impairment on the CDOs, projected cash flows were discounted at the contractual rate and compared to the fair values computed by discounting future projected cash flows at the London Interbank Offered Rate (“LIBOR”) plus an adjustment to reflect the higher risk inherent in these securities given their complex structures and the impact of market factors.

The following table presents a rollforward of life-to-date OTTI recognized in earnings related to all available-for-sale securities held by the Company for the quarters ended March 31, 2014 and 2013.

The following table presents the aggregate amount of unrealized losses and the aggregate related fair values of securities with unrealized losses as of March 31, 2014 and December 31, 2013.
