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 and six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

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 2016 Annual Report on Form 10-K ("2016 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 2016 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 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 the FDIC Agreements. Certain loans that were previously classified as covered loans are no longer covered under the FDIC Agreements, and are included in acquired loans. 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 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 generally 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 status, 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 collateral 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 of 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 in the 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

10

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

Contingent Put and Call Options in Debt Instruments: In March of 2016, the Financial Accounting Standards Board ("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. The adoption of this guidance on January 1, 2017 did not 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. The adoption of this guidance on January 1, 2017 did not 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. The adoption of this guidance on January 1, 2017 resulted in a $638,000 tax benefit to the provision for income tax expense for the six months ended June 30, 2017, recorded in the Company's results of operations. The Company elected to estimate forfeitures, which is consistent with the Company's practice before the adoption of this guidance.

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. Additional amendments to clarify the implementation guidance on the identification of performance obligations and licensing were issued in April of 2016 and narrow-scope improvements and practical expedients were issued in May of 2016.

The guidance was initially effective for annual and interim reporting periods beginning on or after December 15, 2016 but was deferred to 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. The Company's revenue is comprised of net interest income on financial assets and liabilities, which are excluded from the scope of this guidance, and noninterest income. The Company expects that this guidance will change how revenue from certain revenue streams is recognized within wealth management fees but does not expect these changes to have a significant impact on the Company's financial condition, results of operations, or liquidity. The Company continues to evaluate the impact of this guidance on other components of noninterest income. The Company will adopt this guidance on January 1, 2018, using the modified retrospective approach with a cumulative effect adjustment to opening retained earnings, if an adjustment is deemed to be significant.

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 recognize 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.

During 2016, the Company entered into a sale-leaseback transaction that resulted in a deferred gain of $82.5 million, with $78.1 million remaining as of June 30, 2017. Upon adoption of this guidance, the remaining deferred gain will be recognized immediately

12

as a cumulative-effect adjustment to equity. For additional discussion of the sale-leaseback transaction, see Note 8 "Premises, Furniture, and Equipment." Management is evaluating the new guidance and the additional impact to the Company's financial condition, results of operations, or liquidity.

Measurement of Credit Losses on Financial Instruments: In June of 2016, the FASB issued guidance that will require entities to present financial assets measured at amortized cost at the net amount expected to be collected, considering an entity's current estimate of all expected credit losses. In addition, credit losses relating to available-for-sale debt securities will be required to be recorded through an allowance for credit losses, with changes in credit loss estimates recognized through current earnings. This guidance is effective for annual and interim periods beginning after December 15, 2019. Early adoption is permitted, but not for periods beginning before December 15, 2018. Management is evaluating the new guidance and the impact to the Company's financial condition, results of operations, and liquidity.

Classification of Certain Cash Receipts and Cash Payments: In August of 2016, the FASB issued guidance clarifying certain cash flow presentation and classification issues to reduce diversity in practice. This guidance is effective for annual and interim reporting periods beginning on or after December 15, 2017. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's Consolidated Statement of Cash Flows.

Income Taxes: In October of 2016, the FASB issued guidance that requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. 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.

Clarifying the Definition of a Business: In January of 2017, the FASB issued guidance that clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. This guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted. Management will apply this guidance to future transactions upon adoption.

Accounting for Goodwill Impairment: In January of 2017, the FASB issued guidance that simplifies the accounting for goodwill impairment for all entities. The new guidance eliminates the requirement to calculate the implied fair value of goodwill using the second step of the quantitative two-step goodwill impairment model prescribed under current accounting guidance. Under the new guidance, if a reporting unit's carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. This guidance is effective for annual and interim goodwill impairment testing dates beginning after December 15, 2019. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Presentation of Defined Benefit Retirement Plan Costs: In March of 2017, the FASB issued guidance that changes how employers that sponsor defined pension and or other postretirement benefit plans present the net periodic benefit cost in the income statement. Employers will present the service cost component of net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. Other components of net periodic benefit cost will be presented separately from the line item(s) that includes the service cost. 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.

Premium Amortization on Purchased Callable Debt Securities: In March of 2017, the FASB issued guidance that shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date. This guidance is effective for annual and interim periods beginning after December 15, 2018. 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.

Share-based Payment Award Modifications: In May of 2017, the FASB issued guidance to reduce diversity in practice by clarifying when changes to the terms or conditions of a share-based payment award must be accounted for as a modification. 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.

3. ACQUISITIONS

Completed Acquisitions

Standard Bancshares, Inc.

On January 6, 2017, the Company completed the acquisition of Standard Bancshares, Inc. ("Standard"), the holding company for Standard Bank and Trust Company. Pursuant to the terms of the merger agreement, on January 6, 2017, each outstanding share of Standard common stock was canceled and converted into the right to receive 0.4350 of a share of Company common stock. Based on the closing trading price of shares of Company common stock on the NASDAQ on that date of $25.34, the value of the merger consideration per share of Standard common stock was $11.02. Each outstanding Standard stock settled right was redeemed for cash, and each outstanding Standard stock option and each share of Standard phantom stock was canceled and terminated in exchange for the right to receive cash, in each case, pursuant to the terms of the merger agreement. This resulted in an overall transaction value of approximately $580.7 million, which consisted of 21,057,085 shares of Company common stock and $47.1 million in cash. Goodwill of $339.3 million associated with the acquisition was recorded by the Company. All operating systems were converted during the first quarter of 2017.

During the second quarter of 2017, the Company updated the fair value adjustments associated with the Standard transaction. The adjustments were recognized in the current period in accordance with accounting guidance applicable to business combinations. The fair value adjustments, including goodwill, remain preliminary and may change as the Company continues to finalize the fair value of the assets and liabilities acquired.

Premier Asset Management LLC

On February 28, 2017, the Company completed the acquisition of Premier Asset Management LLC ("Premier"), a registered investment advisor based in Chicago, Illinois. At the close of the acquisition, the Company acquired approximately $550.0 million of trust assets under management. The fair value adjustments, including goodwill, remain preliminary and may change as the Company continues to finalize the fair value of the assets and liabilities acquired.

NI Bancshares Corporation

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. As part of the acquisition, the Company acquired all assets and assumed all liabilities of NI Bancshares, which included ten banking offices in northern Illinois and over $700.0 million in trust assets under management. The merger consideration was a combination of Company common stock and cash, at a purchase price of $70.1 million. Goodwill of $22.2 million associated with the acquisition was recorded by the Company. The fair value adjustments associated with this transaction were finalized during the first quarter of 2017.

The unaudited pro forma combined results of operations for the quarters and six months ended June 30, 2017 and 2016 are presented as if the Standard acquisition had occurred on January 1, 2016, the first day of the Company's 2016 fiscal year. The unaudited pro forma combined results of operations are presented for illustrative purposes only and do not necessarily indicate the financial results of the combined companies had the companies actually been combined at the beginning of the period presented. Fair value adjustments included in the following table are preliminary and may be revised. The unaudited pro forma results of operations also does not consider any potential impacts of potential revenue enhancements, anticipated cost savings and expense efficiencies, or asset dispositions, among other factors. Acquisition and integration related expenses directly attributable to the Standard acquisition have been excluded from the following table and are estimated to total $27.0 million, of which $1.2 million and $18.7 million was expensed during the quarter and six months ended June 30, 2017, respectively.

⁽¹⁾  Includes net interest income and total noninterest income.

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. Acquired loans are separated into (i) non-PCI and (ii) 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. PCI loans are accounted for based on estimates of expected future cash flows. 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. For additional discussion regarding significant accounting policies on acquired loans see Note 1, "Summary of Significant Accounting Policies."

Securities acquired in the Standard transaction in the first quarter of 2017 were sold shortly after the acquisition date for $210.2 million, resulting in no gains or losses as the securities were recorded at fair value upon acquisition.

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 outstanding balance of OTTI previously recognized on securities available-for-sale was $23.3 million for both June 30, 2017 and December 31, 2016. During the quarters and six months ended June 30, 2017 and 2016 there were no additions or reductions to the balance of OTTI related to securities available-for-sale.

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 June 30, 2017 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 June 30, 2017 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 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. For a detailed discussion of the CDO valuation methodology, see Note 15, "Fair Value."

⁽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⁾  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 $669,000 as of June 30, 2017 and $834,000 as of December 31, 2016.

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 June 30, 2017 and December 31, 2016.

During 2016, First Midwest Bank (the "Bank") completed a sale-leaseback transaction, whereby the Bank sold to a third party for an aggregate cash purchase price of $150.3 million, 55 properties with book values totaling $58.8 million, owned and operated by the Bank as branches. The Bank concurrently entered into triple net lease agreements with certain affiliates of the third party for each of the branches sold. Subject to the right of the Bank to terminate certain of the lease agreements at the end of the eleventh year, the lease agreements have initial terms of 14 years. Each lease agreement provides the Bank with five consecutive renewal options of five years each. The sale-leaseback transaction resulted in a pre-tax gain of $88.0 million, net of transaction related expenses, with $78.1 million of deferred pre-tax gains remaining as of June 30, 2017.

As of June 30, 2017 and December 31, 2016 assets held-for-sale consisted of former branches that are no longer in operation and parcels of land previously purchased for expansion.

Depreciation on premises, furniture, and equipment totaled $3.5 million and $7.0 million for the quarter and six months ended June 30, 2017, respectively. Depreciation on premises, furniture, and equipment totaled $3.4 million and $6.6 million for the same periods in 2016.

Operating Leases

As of June 30, 2017, the Company was obligated to utilize certain premises and equipment under certain non-cancelable operating leases, which expire at various dates through the year ending December 31, 2033. Many of these leases contain renewal options and certain leases provide options to purchase the leased property during or at the expiration of the lease period at specific prices. Some leases contain escalation clauses calling for rentals to be adjusted for increased real estate taxes and other operating expenses or proportionately adjusted for increases in consumer or other price indices. The following summary reflects the future minimum payments by year required under operating leases that have initial or remaining non-cancelable lease terms in excess of one year as of June 30, 2017.

The Company assumed certain operating leases related to various branches in previous acquisitions. An intangible liability is recorded when the cash flows of a lease exceeds its fair market value. This intangible liability will be accreted into income as a reduction to net occupancy and equipment expense using the straight-line method over the initial term of each lease, which expire between 2018 and 2030. The intangible liability is included in accrued interest and other liabilities in the Consolidated Statements of Financial Condition.

The following table presents the remaining scheduled accretion of the intangible liability by year.

9.  GOODWILL AND OTHER INTANGIBLE ASSETS

The Company's annual goodwill impairment test was performed as of October 1, 2016. It was determined that no impairment existed as of that date or as of June 30, 2017. For a discussion of the accounting policies for goodwill and other intangible assets, see Note 1, "Summary of Significant Accounting Policies" to the Consolidated Financial Statements in the Company's 2016 10-K.

The following table presents changes in the carrying amount of goodwill for the quarters and six months ended June 30, 2017 and 2016.

Changes in the Carrying Amount of Goodwill

(Dollar amounts in thousands)

	Quarters Ended   June 30,					Six Months Ended   June 30,

Ending balance	$	691,527		$	341,513	$	691,527	$	341,513

The decrease in goodwill for the quarter ended June 30, 2017 resulted from measurement period adjustments associated with the Standard transaction. The increase for the six months ended June 30, 2017 resulted from the Standard and Premier acquisitions and measurement period adjustments related to finalizing the fair values of the assets acquired and liabilities assumed in the NI Bancshares acquisition. During the quarter and six months ended June 30, 2016, the increase in goodwill resulted from the NI Bancshares acquisition.

The Company's other intangible assets are core deposit intangibles and trust department customer relationship intangibles, which are being amortized over their estimated useful lives. Other intangible assets are subject to impairment testing when events or circumstances indicate that its carrying amount may not be recoverable. The increase in other intangible assets for the six months ended June 30, 2017 resulted from the Standard and Premier acquisitions. The increase in other intangible assets for the six months ended June 30, 2016 resulted from the NI Bancshares acquisition. During the quarters ended June 30, 2017 and June 30, 2016 there were no events or circumstances to indicate impairment.

11. MATERIAL TRANSACTIONS AFFECTING STOCKHOLDERS' EQUITY

On May 17, 2017, the Company's stockholders approved and adopted an amendment to the Company's Restated Certificate of Incorporation. The amendment increased the Company's authorized common stock by 100,000,000 shares. Following this amendment, the Company is now authorized to issue a total of 251,000,000 shares, including 1,000,000 shares of Preferred Stock, without a par value, and 250,000,000 shares of Common Stock, $0.01 par value per share.

13. 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
	June 30, 2017			December 31, 2016
Gross notional amount outstanding	$	5,708		$	5,958
Derivative liability fair value	(186		)	(282		)
Weighted-average interest rate received	3.08		%	2.63		%
Weighted-average interest rate paid	5.96		%	5.96		%
Weighted-average maturity (in years)	1.35			1.84
Fair value of derivative (1)	$	197		$	296

⁽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 and six months ended June 30, 2017 and 2016, gains or losses related to fair value hedge ineffectiveness were not material.

Cash Flow Hedges

As of June 30, 2017, the Company hedged $980.0 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 $980.0 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 totaling $415.0 million began on various dates between June of 2015 and February of 2017, and mature between June of 2019 and February of 2020. The remaining forward starting interest rate swaps totaling $565.0 million begin at various dates between February of 2018 and February of 2020 and mature between February of 2020 and April of 2022. The weighted-average fixed interest rate to be paid on these interest rate swaps that have not yet begun was 1.96% as of June 30, 2017. These derivative contracts are designated as cash flow hedges.

Cash Flow Hedges

(Dollar amounts in thousands)

	As of
	June 30, 2017			December 31, 2016
Gross notional amount outstanding	$	1,960,000		$	1,470,000
Derivative asset fair value	3,528			5,402
Derivative liability fair value	(7,627		)	(7,390		)
Weighted-average interest rate received	1.51		%	1.37		%
Weighted-average interest rate paid	1.40		%	1.11		%
Weighted-average maturity (in years)	2.75			2.83

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 hedged item impacts earnings. Hedge effectiveness is determined using a regressionanalysis at the inception of the hedge relationship and on an ongoing basis. For the quarters and six months ended June 30, 2017 and 2016, there were no material gains or losses related to cash flow hedge ineffectiveness. As of June 30, 2017, the Company estimates that $303,000 will be reclassified from accumulated other comprehensive loss as a decrease to interest income over the next twelve months.

35

Other Derivative Instruments

The Company also enters into derivative transactions through capital market products with its commercial customers and simultaneously enters into an offsetting interest rate derivative transaction with third-parties. 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 June 30, 2017 and December 31, 2016, the Company's credit exposure was fully secured by the underlying collateral on customer loans and mitigated through netting arrangements with third-parties, therefore, no CVA was recorded. Capital market products income related to commercial customer derivative instruments of $2.2 million and $3.6 million were recorded in noninterest income for the quarters and six months ended June 30, 2017, respectively. There were $2.1 million and $5.3 million of capital market products income recorded for quarters and six months ended June 30, 2016, respectively.

Other Derivative Instruments

(Dollar amounts in thousands)

	As of
	June 30, 2017			December 31, 2016
Gross notional amount outstanding	$	2,252,704		$	1,656,612
Derivative asset fair value	17,370			13,478
Derivative liability fair value	(15,347		)	(13,478		)
Fair value of derivative (1)	15,605			13,753

⁽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 June 30, 2017 and December 31, 2016. 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 June 30, 2017 and December 31, 2016, 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.

36

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 June 30, 2017 and December 31, 2016.

Fair Value of Offsetting Derivatives

	As of June 30, 2017						As of December 31, 2016
	Assets			Liabilities			Assets			Liabilities

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

As of June 30, 2017 and December 31, 2016, 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 June 30, 2017 and December 31, 2016 the Company was in compliance with these provisions.

37

14. 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
	June 30, 2017		December 31, 2016
Commitments to extend credit:
Commercial, industrial, and agricultural	$	1,750,477	$	1,522,152
Commercial real estate	347,330		397,423
Home equity	508,295		426,384
Other commitments (1)	248,320		214,943
Total commitments to extend credit	$	2,854,422	$	2,560,902
Letters of credit	$	137,913	$	100,430
Recourse on assets sold:
Unpaid principal balance of loans sold	$	185,182	$	187,158
Carrying value of recourse obligation (2)	153		142

⁽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. 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. Commercial letters of credit are issued to facilitate transactions between a customer and a third party based on agreed upon terms.

The maximum potential future payments guaranteed by the Company under 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 and six months ended June 30, 2017 and 2016.

Legal Proceedings

In the ordinary course of business, there were certain legal proceedings pending against the Company and its subsidiaries at June 30, 2017. 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 cash flows.

38

15. 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 required to be measured at fair value on a recurring basis between levels of the fair value hierarchy during the periods presented.

39

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.

40

The following table presents the ranges of significant, unobservable inputs calculated using the weighted-average of the Issuers used by the Company as of June 30, 2017 and December 31, 2016.

Significant Unobservable Inputs Used in the Valuation of CDOs

	As of
	June 30, 2017				December 31, 2016
Probability of prepayment	0.0	%	-	10.9%	0.0	%	-	10.9%
Probability of default	15.6	%	-	44.1%	16.7	%	-	46.8%
Loss given default	93.3	%	-	99.2%	93.3	%	-	98.9%
Probability of deferral cure	0.0	%	-	100.0%	7.6	%	-	100.0%

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 quarterly 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 and six months ended June 30, 2017 and 2016 is presented in the following table.

Carrying Value of CDOs

MSRs

The Company services loans for others totaling $626.5 million as of June 30, 2017 and $640.5 million as of December 31, 2016. These loans are owned by third parties and are not included in the Consolidated Statements of Financial Condition. 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 June 30, 2017 and December 31, 2016.

Significant Unobservable Inputs Used in the Valuation of MSRs

	As of
	June 30, 2017				December 31, 2016
Prepayment speed	8.8	%	-	25.3%	7.7	%	-	22.8%
Maturity (months)	8		-	92	12		-	103
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 and six months ended June 30, 2017 and 2016 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.

⁽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 June 30, 2017, 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, 2016, loans held-for-sale consists of 1-4 family mortgage loans, which were originated with the intent to sell, and a corporate loan.

Assets Held-for-Sale

Assets held-for-sale as of June 30, 2017 and December 31, 2016 consists of former branches that are no longer in operation and parcels of land previously purchased for expansion. These properties are being actively marketed and were transferred into the held-for-sale category at their fair value as determined by current appraisals. Based on these valuation methods, they are classified in level 3 of the fair value hierarchy.

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, 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.

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 the 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

44

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 values of senior and subordinated notes are estimated based on quoted market prices of similar instruments. The fair values of junior subordinated debentures are estimated based on quoted market prices of comparable securities when available, or by discounting the expected future cash flows at market interest rates.

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 through over 130 locations throughout the Chicago metropolitan area, northwest Indiana, central and western Illinois, and eastern Iowa. Our principal subsidiary is First Midwest Bank, which provides a broad range of commercial, retail, 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 and six months ended June 30, 2017 and 2016 and Consolidated Statements of Financial Condition as of June 30, 2017 and December 31, 2016. 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 Quarterly Report on Form 10-Q ("Form 10-Q"), as well as in our 2016 Annual Report on Form 10-K ("2016 10-K"). The results of operations for the quarter and six months ended June 30, 2017 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, 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.

Some of these metrics may be presented on a non-U.S. generally accepted accounting principles ("non-GAAP") basis. For detail on our non-GAAP metrics, see the discussion in the section titled "Non-GAAP Financial Information and Reconciliations." Unless otherwise stated, all earnings per common share data included in this section and throughout the remainder of this discussion are presented on a fully diluted basis.

As of June 30, 2017, the Company and the Bank each had total assets of approximately $14.0 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, these requirements are phased in and become applicable to the Company and the Bank 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 2016 10-K, as well as our subsequent filings made with the Securities and Exchange Commission ("SEC").

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This 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," or "assume," and words of similar import. Forward-looking statements 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 2016 10-K, as well as our subsequent filings made with the 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.

CRITICAL ACCOUNTING ESTIMATES

Our consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and are consistent with general practice 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 2016 10-K. There have been no material 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, 2016.

⁽¹⁾  Purchased credit impaired ("PCI") loans with an accretable yield are considered current and are not included in past due loan totals.

⁽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 second quarter and first six months of 2017 was $35.0 million, or $0.34 per share, and $57.8 million, or $0.57 per share, respectively. Performance for all periods presented was impacted by certain significant transactions, which include acquisition and integration related pre-tax expenses of $1.2 million and $19.7 million for the second quarter and first six months of 2017, respectively, and $618,000 and $5.6 million for the same periods in 2016. Excluding these transactions, earnings per share was $0.35 for the second quarter of 2017 compared to $0.32 for the second quarter of 2016 and $0.68 for the first six months of 2017 compared to $0.58 for the same period in 2016. The increase in net income and earnings per share compared to the second quarter and first six months of 2016, excluding certain significant transactions, reflects the benefit of the Standard and Premier acquisitions completed in the first quarter of 2017, loan growth, and increases in fee-based revenues, which were partially offset by higher noninterest expense. In addition, the benefit of the NI Bancshares Corporation ("NI Bancshares") acquisition completed late in the first quarter of 2016 and lower provision for loan losses also contributed to the increase in net income and earnings per share compared to the first six months of 2016. A discussion of net interest income, noninterest income, and noninterest expense is presented in the following section titled "Earnings Performance."

Total loans of $10.2 billion grew by $2.0 billion, or 24.0%, from December 31, 2016. The growth was driven primarily by the acquisition of Standard.

Non-performing assets to loans plus OREO was 1.07% at June 30, 2017, down from 1.12% at December 31, 2016, and up from 0.94% at June 30, 2016. See the following "Loan Portfolio and Credit Quality" section 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 included in our 2016 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. The effect of this adjustment is shown at the bottom of Tables 2 and 3. 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. For a discussion of non-GAAP financial measures, see the section of this Item 2 titled "Non-GAAP Financial Information and Reconciliations."

Table 2 summarizes our average interest-earning assets and interest-bearing liabilities for the quarters ended June 30, 2017and 2016, 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. Table 3 presents this same information for the six months ended June 30, 2017 and 2016.

⁽¹⁾  Interest income and yields on tax-exempt securities and loans are presented on a tax-equivalent basis, assuming a federal income tax rate of 35%. The corresponding income tax impact related to tax-exempt items is recorded in income tax expense. These adjustments have no impact on net income. For further details on the calculation of tax-equivalent net interest income/margin, net interest income and margin (GAAP), and tax-equivalent net interest income/margin, excluding the impact of acquired loan accretion, see the section of this Item 2 titled "Non-GAAP Financial Information and Reconciliations."

⁽²⁾  Non-accrual loans, which totaled $79.2 million as of June 30, 2017 and $37.3 million as of June 30, 2016, 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 Corporate Performing Potential Problem Loans."

Net interest income increased by 30.7% and 36.4% compared to the second quarter and first six months of 2016, respectively. Compared to both prior periods, the increase in net interest income was driven primarily by the acquisition of interest-earning assets and acquired loan accretion from the Standard transaction early in the first quarter of 2017. Higher interest rates and loan growth also contributed to the increase in net interest income compared to both prior periods.

52

Acquired loan accretion contributed $8.8 million and $20.1 million to net interest income for the second quarter and first six months of 2017, respectively, higher than $4.9 million and $7.4 million for the same periods in 2016.

Tax-equivalent net interest margin for both the second quarter and first six months of 2017 was 3.88%, increasing by 16 and 19 basis points from the same periods in 2016. The rise in tax-equivalent net interest margin was impacted by an 8 and 18 basis point increase in acquired loan accretion compared to the second quarter and first six months of 2016, respectively, and higher interest rates. In addition, compared to the first six months of 2016, the impact of adding a greater mix of higher-yielding fixed-rate loans acquired from Standard contributed to the increase, which was more than offset by growth in the securities portfolio and the continued shift of loan originations and mix to lower-yielding floating rate loans.

Total average interest-earning assets rose by $2.4 billion and $2.8 billion from the second quarter and first six months of 2016, respectively. Compared to both prior periods, the increase resulted from interest-earning assets acquired in the Standard transaction, loan growth, and security purchases. In addition, interest-earning assets acquired in the NI Bancshares transaction contributed to the increase compared to the first six months of 2016.

Compared to the second quarter and first six months of 2016, total average funding sources increased by $2.2 billion and $2.6 billion, respectively. The increase compared to both prior periods resulted primarily from deposits acquired in the Standard transaction and the addition of FHLB advances. Deposits acquired in the NI Bancshares transaction also contributed to the increase compared to the first six months of 2016.

Noninterest Income

A summary of noninterest income for the quarters and six months ended June 30, 2017 and 2016 is presented in the following table.

N/M - Not meaningful.

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

⁽⁴⁾  Other income consists of various items, including bank-owned life insurance ("BOLI") income, safe deposit box rentals, miscellaneous recoveries, and gains on the sales of various assets.

Total fee-based revenues grew by 14.7% and 13.7% compared to the second quarter and first six months of 2016, respectively. Compared to both prior periods, the increase in fee-based revenues resulted primarily from services provided to customers acquired in the Standard and Premier transactions completed in the first quarter of 2017, organic growth in treasury management services, and a rise in card-based fees resulting from higher transaction volumes. In addition, the full quarter impact of customers acquired

53

in the NI Bancshares transaction late in the first quarter of 2016 contributed to the increase in fee-based revenues compared to the first six months of 2016.

Growth in capital market products income compared to the second quarter of 2016 was driven by increased sales to commercial clients. The decline in capital market products income from the first six months of 2016 was consistent with loan production during the first six months of 2017.

Mortgage banking income resulted primarily from sales of $59.5 million and $114.1 million of 1-4 family mortgage loans in the secondary market during the second quarter and first six months of 2017, respectively, up from sales of $52.1 million and $90.8 million for the same periods in 2016. In addition, mortgage banking income for the second quarter of 2017 was impacted by a decrease in the fair value of mortgage servicing rights, which fluctuates from quarter to quarter.

Total noninterest income increased by 18.8% and 15.1% from the second quarter and first six months of 2016, respectively. Other income was elevated in the second quarter and first six months of 2017 due to net gains from the disposition of branch properties and other miscellaneous items.

Noninterest Expense

A summary of noninterest expense for the quarters and six months ended June 30, 2017 and 2016 is presented in the following table.

Total noninterest expense	$	99,751	$	81,354	22.6		$	216,393	$	163,943	32.0

⁽¹⁾  The related merchant servicing fees are included in noninterest income for each period presented.

Total noninterest expense increased by 22.6% and 32.0% compared to the second quarter and first six months of 2016, respectively, and was impacted by certain significant transactions including acquisition and integration related expenses associated with completed and pending acquisitions. Excluding these certain significant transactions, total noninterest expense increased by 22.1% and 24.2% from the second quarter and first six months of 2016, respectively.

Compared to both prior periods, the increase in total noninterest expense, excluding certain significant transactions, resulted largely from operating costs associated with the Standard transaction, which impacted most categories. The full quarter impact of the NI Bancshares transaction also contributed to the increase compared to the first six months of 2016.

Excluding operating costs associated with completed acquisitions, the rise in salaries and employee benefits compared to both prior periods was also impacted by merit increases and investments in additional talent to support growth, partially offset by higher deferred salaries due to loan growth. Higher loan remediation expenses and certain costs associated with organizational growth contributed to the increase in professional services compared to both prior periods presented. The decrease in advertising and

54

promotions expense compared to the second quarter and first six months of 2016 resulted from the timing of certain advertising costs. Net OREO expense increased from both prior periods due primarily to higher valuation adjustments.

Acquisition and integration related expenses for the second quarter and first six months of 2017 resulted from the acquisitions of Standard and Premier during the first quarter of 2017. For the second quarter and first six months of 2016, acquisition and integration related expenses resulted from the acquisition of NI Bancshares during the first quarter of 2016. These expenses fluctuate based on the size and timing of each transaction.

Income Taxes

Our provision for income taxes includes both federal and state income tax expense. An analysis of the provision for income taxes for the quarters and six months ended June 30, 2017 and 2016 is detailed in the following table.

Table 6

Income Tax Expense Analysis

(Dollar amounts in thousands)

	Quarters Ended   June 30,						Six Months Ended   June 30,
	2017			2016			2017			2016
Income before income tax expense	$	54,538		$	38,364		$	88,126		$	64,822
Income tax expense:
Federal income tax expense	$	16,159		$	10,732		$	25,053		$	17,833
State income tax expense	3,429			2,365			5,268			3,760
Total income tax expense	$	19,588		$	13,097		$	30,321		$	21,593
Effective income tax rate	35.9		%	34.1		%	34.4		%	33.3		%

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 increase in total income tax expense and the effective tax rate for the quarter and six months ended June 30, 2017 compared to the same periods in 2016 resulted primarily from higher levels of income subject to tax at statutory rates and a decrease in tax-exempt income. For the six months ended June 30, 2017, this increase was partly offset by tax benefits of $638,000 related to the implementation of Financial Accounting Standards Board ("FASB") guidance on employee share-based payments recognized in the first quarter of 2017.

On July 6, 2017, Illinois enacted legislation increasing the overall corporate income and replacement tax rate from 7.75% to 9.50%. The rate increase, effective on July 1, 2017, will increase the Company's effective tax rate and expense in future quarters, which is not expected to be material, and will also result in a non-cash tax benefit related to the write-up of deferred tax assets in the third quarter of 2017.

Our accounting policies regarding the recognition of income taxes in the Consolidated Statements of Financial Condition and Income are described in Notes 1 and 15 to the Consolidated Financial Statements of our 2016 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.

55

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 June 30, 2017, our securities available-for-sale portfolio totaled $1.9 billion, consistent with December 31, 2016.

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 $33.5 million and miscellaneous other securities with a fair value of $7.0 million.

Investments in municipal securities comprised $264.4 million, or 13.9%, of the total securities available-for-sale portfolio at June 30, 2017. 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 was 4.05 years and 3.43%, respectively, as of June 30, 2017, down from 4.27 years and 3.72% as of December 31, 2016. The decrease resulted primarily from maturities and sales of investment securities that were reinvested into lower-duration CMOs and MBSs.

Realized Gains and Losses

There were $284,000 of net securities gains recognized during both the second quarter and first six months of 2017, on securities with carrying values of $30.7 million. In addition, $214.1 million of securities were acquired in the Standard transaction during the first quarter of 2017, of which $210.2 million were sold shortly after the acquisition date and resulted in no gains or losses as they were recorded at fair value upon acquisition. No impairment charges were recognized during the second quarter or first six months of 2017.

Net securities gains for the second quarter and first six months of 2016 were $23,000 and $910,000, respectively, on securities with carrying values of $8.0 million and $38.6 million for the same periods. No impairment charges were recognized during the second quarter or first six months of 2016.

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 June 30, 2017, net unrealized losses totaled $27.8 million compared to net unrealized losses of $38.1 million as of December 31, 2016.

57

Net unrealized losses in the CMO portfolio totaled $11.7 million as of June 30, 2017 compared to $16.7 million as of December 31, 2016. CMOs 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 June 30, 2017 represents other-than-temporary securities impairment ("OTTI") related to credit deterioration. In addition, we do not intend to sell the CMOs with unrealized losses 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 investments in CDOs are supported by the credit of the underlying banks and insurance companies. The net unrealized losses on these securities were $14.3 million as of June 30, 2017 and $14.4 million as of December 31, 2016. We do not believe the unrealized losses on the CDOs as of June 30, 2017 represent OTTI related to credit deterioration. In addition, we do not intend to sell the CDOs with unrealized losses 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 15 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 82.4% of total loans at June 30, 2017. 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 corporate performing potential problem loans to monitor and mitigate potential and current risks in the portfolio.

Total loans of $10.2 billion grew by 24.0% from December 31, 2016. Excluding loans acquired in the Standard transaction, total loans grew by 4.5% from December 31, 2016. The addition of 1-4 family mortgages, installment loans, and shorter-duration, floating rate home equity loans contributed to the increase in total loans. In addition, growth in commercial and industrial loans, primarily within our sector-based lending business units, and multi-family loans contributed to the increase in total loans.

Commercial, Industrial, and Agricultural Loans

Commercial, industrial, and agricultural loans represent 37.5% of total loans, and totaled $3.8 billion at June 30, 2017, an increase of $627.0 million, or 19.5%, from December 31, 2016. 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.

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 44.9% of total loans, and totaled $4.6 billion at June 30, 2017, increasing by $965.6 million, or 26.6%, from December 31, 2016.

The mix of properties securing the loans in our commercial real estate portfolio is balanced between owner-occupied and investor categories and is diverse in terms of type and geographic location, generally within the Company's markets. Approximately 44% of the commercial real estate portfolio, excluding multi-family and construction loans, is owner-occupied as of June 30, 2017. Using outstanding loan balances, non-owner occupied commercial real estate loans to total capital was 217% and construction loans to total capital was 31% as of June 30, 2017. Non-owner-occupied (investor) commercial real estate is calculated in accordance with federal banking agency guidelines and includes construction, multi-family, non-farm non-residential property, and commercial real estate not secured by real estate loans.

Consumer Loans

Consumer loans represent 17.6% of total loans, and totaled $1.8 billion at June 30, 2017, an increase of $385.4 million, or 27.3%, from December 31, 2016. 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⁾  PCI loans with an accretable yield are considered current and are not included in past due loan totals.

Total non-performing assets represented 1.07% of total loans and OREO at June 30, 2017, down from 1.12% at December 31, 2016 and up from 0.94% at June 30, 2016. Included in non-performing assets as of June 30, 2017 was $6.9 million of OREO acquired in the Standard transaction.

Non-accrual loans increased by $19.9 million from December 31, 2016, due primarily to the transfer of two corporate loan relationships to non-accrual status, which was driven by operating pressures unique to these borrowers. The Company has established specific reserves and implemented remediation plans associated with these borrowers.

62

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 restructured loans remain classified as TDRs for the remaining term of these loans.

Corporate Performing Potential Problem Loans

Corporate performing potential problem loans consist of special mention loans and substandard loans, excluding accruing 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.

⁽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 corporate performing potential problem loans excludes accruing TDRs of $669,000 as of June 30, 2017 and $834,000 as of December 31, 2016.

⁽⁴⁾  Includes corporate PCI performing potential problem loans.

Corporate performing potential problem loans were 3.9% of corporate loans at June 30, 2017, lower than 4.4% at December 31, 2016. The Standard acquisition added corporate performing potential problem loans that were designated as PCI.

OREO

OREO consists of properties acquired as the result of borrower defaults on loans. OREO was $26.5 million at June 30, 2017, consistent with December 31, 2016 and down from $30.0 million at June 30, 2016. As of June 30, 2017, total OREO includes $6.9 million that was acquired in the Standard transaction.

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.

65

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 June 30, 2017.

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.

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 June 30, 2017 and December 31, 2016.

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

⁽²⁾  The remaining acquisition adjustment consists of $52.8 million and $37.5 million relating to PCI and non-purchased credit impaired ("Non-PCI") loans, respectively, as of June 30, 2017, and $10.8 million and $11.8 million relating to PCI and Non-PCI loans, respectively, as of December 31, 2016.

⁽³⁾  The allowance for credit losses to total loans, excluding acquired loans is a non-GAAP financial measure. For a discussion of non-GAAP financial measures, see the section of this Item 2 titled "Non-GAAP Financial Information and Reconciliations."

Excluding acquired loans, the allowance for credit losses to total loans was 1.10% as of June 30, 2017. The acquisition adjustment increased by $67.7 million during the first six months of 2017, driven primarily by the Standard transaction. This was partially offset by acquired loan accretion, resulting in a remaining acquisition adjustment as a percent of acquired loans of 4.51%. Acquired loans that are renewed are no longer classified as acquired loans. These loans totaled $233.6 million and $117.6 million as of June 30, 2017 and December 31, 2016, respectively, 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 $2.9 million on acquired loans.

Activity in the Allowance for Credit Losses

The allowance for credit losses was $93.4 million as of June 30, 2017, an increase of $6.3 million from December 31, 2016, and represents 0.91% of total loans compared to 1.06% at December 31, 2016.

The provision for loan losses was $8.2 million for the quarter ended June 30, 2017, increasing from $5.3 million and consistent with $8.1 million for the quarters ended December 31, 2016 and June 30, 2016, respectively. The increase compared to the quarter ended December 31, 2016 resulted primarily from loan growth.

Total net loan charge-offs to average loans for the second quarter of 2017 was 16 basis points, or $4.0 million, decreasing from 22 and 26 basis points for both the fourth and second quarters of 2016, respectively.

The rise in average core deposits compared to both prior periods resulted primarily from $1.7 billion in core deposits assumed in the Standard transaction, which contributed $1.6 billion to average core deposits in the second quarter of 2017, as well as organic growth. The addition of FHLB advances also contributed to the rise in average funding sources compared to the second quarter of 2016.

Average borrowed funds totaled $643.1 million for the first six months of 2017, increasing by $260.8 million compared to the same period in 2016. This increase was due primarily to higher levels of FHLB advances during the first six months of 2017. The weighted-average rate on FHLB advances for both periods presented was impacted by the hedging of $415.0 million and $325.0 million in FHLB advances as of June 30, 2017 and 2016, respectively, using interest rate swaps through which the Company receives variable amounts and pays fixed amounts. The weighted-average interest rate paid on these interest rate swaps was 2.17% and 2.19% as of June 30, 2017 and 2016, respectively. For a detailed discussion of interest rate swaps, see Note 13 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 2016 10-K. In addition, financial institutions, such as the Company and the Bank, with average total consolidated assets greater than $10 billion are required by the Dodd-Frank Act to conduct an annual company-run stress test of capital. The Company submitted its first required stress test report for the July 31, 2017 reporting date and the Bank will become subject to these stress test requirements starting with the July 31, 2018 reporting date.

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 levels 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 June 30, 2017 and December 31, 2016.

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. For a discussion of non-GAAP financial measures, see the section of this Item 2 titled "Non-GAAP Financial Information and Reconciliations."

Overall, the Company's regulatory capital ratios decreased compared to December 31, 2016 due to the Standard and Premier acquisitions, which was partly offset by an increase in retained earnings over the first six months of 2017.

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 $0.10 per common share during the second quarter of 2017, an increase from $0.09 during the first quarter of 2017.

NON-GAAP FINANCIAL INFORMATION AND RECONCILIATIONS

The Company's accounting and reporting policies conform to GAAP and general practices 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 non-GAAP financial measures include earnings per share ("EPS"), excluding certain significant transactions, the efficiency ratio, return on average assets, excluding certain significant transactions, tax-equivalent net interest income (including its individual components), tax-equivalent net interest margin, tax-equivalent net interest margin, excluding the impact of acquired loan accretion, tangible common equity to tangible assets, tangible common equity, excluding accumulated other comprehensive loss, to tangible assets, tangible common equity to risk-weighted assets, return on average tangible common equity, return on average tangible common equity, excluding certain significant transactions, and allowance for credit losses to loans, excluding acquired loans.

The Company presents EPS, the efficiency ratio, return on average assets, and return on average tangible common equity, all excluding certain significant transactions. Certain significant transactions include acquisition and integration expenses for all periods presented. Management believes excluding these transactions from EPS, the efficiency ratio, return on average assets, and return on average tangible common equity are useful in assessing the Company's underlying operational performance since these transactions do not pertain to its core business operations and their exclusion facilitates better comparability between periods. Management believes that excluding acquisition and integration related expenses from these metrics is useful to the Company, as well as analysts and investors, since these expenses can vary significantly based on the size, type, and structure of each acquisition. Additionally, management believes excluding these transactions from these metrics enhances comparability for peer comparison purposes.

The tax-equivalent adjustment to net interest income and net interest margin recognizes the income tax savings when comparing taxable and tax-exempt assets and assumes a 35% tax rate. Management believes that it is standard practice in the banking industry to present net interest income and net interest margin on a fully tax-equivalent basis and that it enhances comparability for peer comparison purposes. In addition, management believes that the tax-equivalent net interest margin, excluding the impact of acquired loan accretion, enhances comparability for peer comparison purposes and is useful to the Company, as well as analysts and investors, since acquired loan accretion income may fluctuate based on the size of each acquisition, as well as from period to period.

In management's view, tangible common equity measures are capital adequacy metrics meaningful to the Company, as well as analysts and investors, in assessing the Company's use of equity and in facilitating comparisons with peers. 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.

The Company presents the allowance for credit losses to total loans, excluding acquired loans. Management believes excluding acquired loans is useful as it facilitates better comparability between periods as these 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. Additionally, management believes excluding these transactions from these metrics enhances comparability for peer comparison purposes. See Table 17 in the section of this Item 2 titled "Loan Portfolio and Credit Quality" for details on the calculation of this measure.

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. See the following reconciliations for details on the calculation of these measures to the extent presented herein.

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 2016 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 June 30, 2017 and December 31, 2016, 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, and including the impact of hedging certain corporate variable rate loans using interest rate swaps through which the Company receives fixed amounts and pays variable amounts, 50% of the loan portfolio consisted of fixed rate loans and 50% were floating rate loans as of June 30, 2017, compared to 48% and 52%, respectively, as of December 31, 2016.

As of June 30, 2017, investments, consisting of securities and interest-bearing deposits in other banks, are more heavily weighted toward fixed rate securities at 95% of the total compared to 5% for floating rate interest-bearing deposits in other banks. This compares to investments comprising 95% of fixed rate securities and 5% of floating rate interest-bearing deposits in other banks as of December 31, 2016. 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 $122.0 million, or 2%, of the floating rate loan portfolio as of June 30, 2017, compared to $271.5 million, or 5%, of the floating rate loan portfolio as of December 31, 2016. On the liability side of the balance sheet, 86% of deposits as of both June 30, 2017 and December 31, 2016 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.

Analysis of Net Interest Income Sensitivity

(Dollar amounts in thousands)

	Immediate Change in Rates
	+300			+200			+100			-100
As of June 30, 2017
Dollar change	$	63,732		$	38,413		$	20,364		$	(43,532	)
Percent change	14.1		%	8.5		%	4.5		%	(9.6		)%
As of December 31, 2016
Dollar change	$	44,092		$	25,412		$	12,763		$	(26,013	)
Percent change	12.3		%	7.1		%	3.6		%	(7.2		)%

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 June 30, 2017 would increase net interest income by $38.4 million, or 8.5%, over the next twelve months compared to no change in interest rates. This same measure was $25.4 million, or 7.1%, as of December 31, 2016.

Overall, positive interest rate risk volatility as of June 30, 2017 increased compared to December 31, 2016. This increase was driven primarily by a reduction in short-term FHLB advances, resulting from the sale of securities acquired in the Standard transaction. In addition, continued growth in floating rate loans funded with both core and time deposits contributed to the increase.

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 June 30, 2017. 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 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 2016 Form 10-K. However, these factors may not be the only risks or uncertainties the Company faces.

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 June 30, 2017, and the related condensed consolidated statements of income and consolidated statements of comprehensive income for the three- and six-month periods ended June 30, 2017 and 2016, and the consolidated statements of changes in stockholders’ equity and the condensed consolidated statements of cash flows for the six-month periods ended June 30, 2017 and 2016. 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, 2016, and the related consolidated statements of income, comprehensive income, stockholders’ 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 28, 2017.

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 and six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

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 2016 Annual Report on Form 10-K ("2016 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 2016 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 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 the FDIC Agreements. Certain loans that were previously classified as covered loans are no longer covered under the FDIC Agreements, and are included in acquired loans. 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 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 generally 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 status, 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 collateral 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 of 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 in the 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.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent Accounting Pronouncements

RECENT ACCOUNTING PRONOUNCEMENTS

Adopted Accounting Pronouncements

Contingent Put and Call Options in Debt Instruments: In March of 2016, the Financial Accounting Standards Board ("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. The adoption of this guidance on January 1, 2017 did not 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. The adoption of this guidance on January 1, 2017 did not 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. The adoption of this guidance on January 1, 2017 resulted in a $638,000 tax benefit to the provision for income tax expense for the six months ended June 30, 2017, recorded in the Company's results of operations. The Company elected to estimate forfeitures, which is consistent with the Company's practice before the adoption of this guidance.

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. Additional amendments to clarify the implementation guidance on the identification of performance obligations and licensing were issued in April of 2016 and narrow-scope improvements and practical expedients were issued in May of 2016.

The guidance was initially effective for annual and interim reporting periods beginning on or after December 15, 2016 but was deferred to 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. The Company's revenue is comprised of net interest income on financial assets and liabilities, which are excluded from the scope of this guidance, and noninterest income. The Company expects that this guidance will change how revenue from certain revenue streams is recognized within wealth management fees but does not expect these changes to have a significant impact on the Company's financial condition, results of operations, or liquidity. The Company continues to evaluate the impact of this guidance on other components of noninterest income. The Company will adopt this guidance on January 1, 2018, using the modified retrospective approach with a cumulative effect adjustment to opening retained earnings, if an adjustment is deemed to be significant.

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 recognize 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.

During 2016, the Company entered into a sale-leaseback transaction that resulted in a deferred gain of $82.5 million, with $78.1 million remaining as of June 30, 2017. Upon adoption of this guidance, the remaining deferred gain will be recognized immediately as a cumulative-effect adjustment to equity. For additional discussion of the sale-leaseback transaction, see Note 8 "Premises, Furniture, and Equipment." Management is evaluating the new guidance and the additional impact to the Company's financial condition, results of operations, or liquidity.

Measurement of Credit Losses on Financial Instruments: In June of 2016, the FASB issued guidance that will require entities to present financial assets measured at amortized cost at the net amount expected to be collected, considering an entity's current estimate of all expected credit losses. In addition, credit losses relating to available-for-sale debt securities will be required to be recorded through an allowance for credit losses, with changes in credit loss estimates recognized through current earnings. This guidance is effective for annual and interim periods beginning after December 15, 2019. Early adoption is permitted, but not for periods beginning before December 15, 2018. Management is evaluating the new guidance and the impact to the Company's financial condition, results of operations, and liquidity.

Classification of Certain Cash Receipts and Cash Payments: In August of 2016, the FASB issued guidance clarifying certain cash flow presentation and classification issues to reduce diversity in practice. This guidance is effective for annual and interim reporting periods beginning on or after December 15, 2017. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's Consolidated Statement of Cash Flows.

Income Taxes: In October of 2016, the FASB issued guidance that requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. 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.

Clarifying the Definition of a Business: In January of 2017, the FASB issued guidance that clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. This guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted. Management will apply this guidance to future transactions upon adoption.

Accounting for Goodwill Impairment: In January of 2017, the FASB issued guidance that simplifies the accounting for goodwill impairment for all entities. The new guidance eliminates the requirement to calculate the implied fair value of goodwill using the second step of the quantitative two-step goodwill impairment model prescribed under current accounting guidance. Under the new guidance, if a reporting unit's carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. This guidance is effective for annual and interim goodwill impairment testing dates beginning after December 15, 2019. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Presentation of Defined Benefit Retirement Plan Costs: In March of 2017, the FASB issued guidance that changes how employers that sponsor defined pension and or other postretirement benefit plans present the net periodic benefit cost in the income statement. Employers will present the service cost component of net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. Other components of net periodic benefit cost will be presented separately from the line item(s) that includes the service cost. 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.

Premium Amortization on Purchased Callable Debt Securities: In March of 2017, the FASB issued guidance that shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date. This guidance is effective for annual and interim periods beginning after December 15, 2018. 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.

Share-based Payment Award Modifications: In May of 2017, the FASB issued guidance to reduce diversity in practice by clarifying when changes to the terms or conditions of a share-based payment award must be accounted for as a modification. 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.

Acquisitions

ACQUISITIONS

Completed Acquisitions

Standard Bancshares, Inc.

On January 6, 2017, the Company completed the acquisition of Standard Bancshares, Inc. ("Standard"), the holding company for Standard Bank and Trust Company. Pursuant to the terms of the merger agreement, on January 6, 2017, each outstanding share of Standard common stock was canceled and converted into the right to receive 0.4350 of a share of Company common stock. Based on the closing trading price of shares of Company common stock on the NASDAQ on that date of $25.34, the value of the merger consideration per share of Standard common stock was $11.02. Each outstanding Standard stock settled right was redeemed for cash, and each outstanding Standard stock option and each share of Standard phantom stock was canceled and terminated in exchange for the right to receive cash, in each case, pursuant to the terms of the merger agreement. This resulted in an overall transaction value of approximately $580.7 million, which consisted of 21,057,085 shares of Company common stock and $47.1 million in cash. Goodwill of $339.3 million associated with the acquisition was recorded by the Company. All operating systems were converted during the first quarter of 2017.

During the second quarter of 2017, the Company updated the fair value adjustments associated with the Standard transaction. The adjustments were recognized in the current period in accordance with accounting guidance applicable to business combinations. The fair value adjustments, including goodwill, remain preliminary and may change as the Company continues to finalize the fair value of the assets and liabilities acquired.

Premier Asset Management LLC

On February 28, 2017, the Company completed the acquisition of Premier Asset Management LLC ("Premier"), a registered investment advisor based in Chicago, Illinois. At the close of the acquisition, the Company acquired approximately $550.0 million of trust assets under management. The fair value adjustments, including goodwill, remain preliminary and may change as the Company continues to finalize the fair value of the assets and liabilities acquired.

NI Bancshares Corporation

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. As part of the acquisition, the Company acquired all assets and assumed all liabilities of NI Bancshares, which included ten banking offices in northern Illinois and over $700.0 million in trust assets under management. The merger consideration was a combination of Company common stock and cash, at a purchase price of $70.1 million. Goodwill of $22.2 million associated with the acquisition was recorded by the Company. The fair value adjustments associated with this transaction were finalized during the first quarter of 2017.

The following table presents the assets acquired and liabilities assumed, net of the fair value adjustments, in the Standard and NI Bancshares transactions as of the acquisition date. The assets acquired and liabilities assumed, both intangible and tangible, were recorded at their estimated fair values as of the acquisition date and have been accounted for under the acquisition method of accounting.

Expenses related to the acquisition and integration of the transactions above totaled $1.2 million and $19.7 million during the quarter and six months ended June 30, 2017, respectively, and are reported as a separate component within noninterest expense in the Condensed Consolidated Statements of Income. Expenses related to the acquisition and integration of the transactions above totaled $618,000 and $5.6 million during the quarter and six months ended June 30, 2016, respectively. The acquisition of Standard was considered material to the Company's financial statements; therefore, pro forma financial data and related disclosures are included in the following tables.

The unaudited pro forma combined results of operations for the quarters and six months ended June 30, 2017 and 2016 are presented as if the Standard acquisition had occurred on January 1, 2016, the first day of the Company's 2016 fiscal year. The unaudited pro forma combined results of operations are presented for illustrative purposes only and do not necessarily indicate the financial results of the combined companies had the companies actually been combined at the beginning of the period presented. Fair value adjustments included in the following table are preliminary and may be revised. The unaudited pro forma results of operations also does not consider any potential impacts of potential revenue enhancements, anticipated cost savings and expense efficiencies, or asset dispositions, among other factors. Acquisition and integration related expenses directly attributable to the Standard acquisition have been excluded from the following table and are estimated to total $27.0 million, of which $1.2 million and $18.7 million was expensed during the quarter and six months ended June 30, 2017, respectively.

Net income	35,652		29,304		68,386		52,465

⁽¹⁾  Includes net interest income and total noninterest income.

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. Acquired loans are separated into (i) non-PCI and (ii) 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. PCI loans are accounted for based on estimates of expected future cash flows. 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. For additional discussion regarding significant accounting policies on acquired loans see Note 1, "Summary of Significant Accounting Policies."

The following table presents additional detail for loans acquired in the Standard transaction at the acquisition date.

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 $1.1 billion for both June 30, 2017 and December 31, 2016. No securities held-to-maturity were pledged as of June 30, 2017 or December 31, 2016.

During the quarters and six months ended June 30, 2017 and 2016 there were no material gross trading gains (losses). The following table presents net realized gains on securities available-for-sale for the quarters and six months ended June 30, 2017 and 2016.

Securities acquired in the Standard transaction in the first quarter of 2017 were sold shortly after the acquisition date for $210.2 million, resulting in no gains or losses as the securities were recorded at fair value upon acquisition.

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 outstanding balance of OTTI previously recognized on securities available-for-sale was $23.3 million for both June 30, 2017 and December 31, 2016. During the quarters and six months ended June 30, 2017 and 2016 there were no additions or reductions to the balance of OTTI related to securities available-for-sale.

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 June 30, 2017 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 June 30, 2017 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 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. For a detailed discussion of the CDO valuation methodology, see Note 15, "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 June 30, 2017 and December 31, 2016.

During 2016, First Midwest Bank (the "Bank") completed a sale-leaseback transaction, whereby the Bank sold to a third party for an aggregate cash purchase price of $150.3 million, 55 properties with book values totaling $58.8 million, owned and operated by the Bank as branches. The Bank concurrently entered into triple net lease agreements with certain affiliates of the third party for each of the branches sold. Subject to the right of the Bank to terminate certain of the lease agreements at the end of the eleventh year, the lease agreements have initial terms of 14 years. Each lease agreement provides the Bank with five consecutive renewal options of five years each. The sale-leaseback transaction resulted in a pre-tax gain of $88.0 million, net of transaction related expenses, with $78.1 million of deferred pre-tax gains remaining as of June 30, 2017.

As of June 30, 2017 and December 31, 2016 assets held-for-sale consisted of former branches that are no longer in operation and parcels of land previously purchased for expansion.

Depreciation on premises, furniture, and equipment totaled $3.5 million and $7.0 million for the quarter and six months ended June 30, 2017, respectively. Depreciation on premises, furniture, and equipment totaled $3.4 million and $6.6 million for the same periods in 2016.

Operating Leases

As of June 30, 2017, the Company was obligated to utilize certain premises and equipment under certain non-cancelable operating leases, which expire at various dates through the year ending December 31, 2033. Many of these leases contain renewal options and certain leases provide options to purchase the leased property during or at the expiration of the lease period at specific prices. Some leases contain escalation clauses calling for rentals to be adjusted for increased real estate taxes and other operating expenses or proportionately adjusted for increases in consumer or other price indices. The following summary reflects the future minimum payments by year required under operating leases that have initial or remaining non-cancelable lease terms in excess of one year as of June 30, 2017.

As of June 30, 2017, deferred pre-tax gains of $78.1 million related to the sale-lease back transaction will be accreted as a reduction to lease expense in other expenses on the Condensed Consolidated Statements of Income on a straight-line basis over the initial terms of the leases.

The Company assumed certain operating leases related to various branches in previous acquisitions. An intangible liability is recorded when the cash flows of a lease exceeds its fair market value. This intangible liability will be accreted into income as a reduction to net occupancy and equipment expense using the straight-line method over the initial term of each lease, which expire between 2018 and 2030. The intangible liability is included in accrued interest and other liabilities in the Consolidated Statements of Financial Condition.

GOODWILL AND OTHER INTANGIBLE ASSETS

The Company's annual goodwill impairment test was performed as of October 1, 2016. It was determined that no impairment existed as of that date or as of June 30, 2017. For a discussion of the accounting policies for goodwill and other intangible assets, see Note 1, "Summary of Significant Accounting Policies" to the Consolidated Financial Statements in the Company's 2016 10-K.

The following table presents changes in the carrying amount of goodwill for the quarters and six months ended June 30, 2017 and 2016.

Ending balance	$	691,527		$	341,513	$	691,527	$	341,513

The decrease in goodwill for the quarter ended June 30, 2017 resulted from measurement period adjustments associated with the Standard transaction. The increase for the six months ended June 30, 2017 resulted from the Standard and Premier acquisitions and measurement period adjustments related to finalizing the fair values of the assets acquired and liabilities assumed in the NI Bancshares acquisition. During the quarter and six months ended June 30, 2016, the increase in goodwill resulted from the NI Bancshares acquisition.

The Company's other intangible assets are core deposit intangibles and trust department customer relationship intangibles, which are being amortized over their estimated useful lives. Other intangible assets are subject to impairment testing when events or circumstances indicate that its carrying amount may not be recoverable. The increase in other intangible assets for the six months ended June 30, 2017 resulted from the Standard and Premier acquisitions. The increase in other intangible assets for the six months ended June 30, 2016 resulted from the NI Bancshares acquisition. During the quarters ended June 30, 2017 and June 30, 2016 there were no events or circumstances to indicate impairment.

Hedge ineffectiveness is recognized in other noninterest income in the Condensed Consolidated Statements of Income. For the quarters and six months ended June 30, 2017 and 2016, gains or losses related to fair value hedge ineffectiveness were not material.

Cash Flow Hedges

As of June 30, 2017, the Company hedged $980.0 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 $980.0 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 totaling $415.0 million began on various dates between June of 2015 and February of 2017, and mature between June of 2019 and February of 2020. The remaining forward starting interest rate swaps totaling $565.0 million begin at various dates between February of 2018 and February of 2020 and mature between February of 2020 and April of 2022. The weighted-average fixed interest rate to be paid on these interest rate swaps that have not yet begun was 1.96% as of June 30, 2017. These derivative contracts are designated as cash flow hedges.

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 hedged item impacts earnings. Hedge effectiveness is determined using a regressionanalysis at the inception of the hedge relationship and on an ongoing basis. For the quarters and six months ended June 30, 2017 and 2016, there were no material gains or losses related to cash flow hedge ineffectiveness. As of June 30, 2017, the Company estimates that $303,000 will be reclassified from accumulated other comprehensive loss as a decrease to interest income over the next twelve months.

Other Derivative Instruments

The Company also enters into derivative transactions through capital market products with its commercial customers and simultaneously enters into an offsetting interest rate derivative transaction with third-parties. 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 June 30, 2017 and December 31, 2016, the Company's credit exposure was fully secured by the underlying collateral on customer loans and mitigated through netting arrangements with third-parties, therefore, no CVA was recorded. Capital market products income related to commercial customer derivative instruments of $2.2 million and $3.6 million were recorded in noninterest income for the quarters and six months ended June 30, 2017, respectively. There were $2.1 million and $5.3 million of capital market products income recorded for quarters and six months ended June 30, 2016, respectively.

⁽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 June 30, 2017 and December 31, 2016. 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 June 30, 2017 and December 31, 2016, 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 June 30, 2017 and December 31, 2016.

As of June 30, 2017 and December 31, 2016, 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 June 30, 2017 and December 31, 2016 the Company was in compliance with these provisions.

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.

Carrying value of recourse obligation (2)	153		142

⁽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. 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. Commercial letters of credit are issued to facilitate transactions between a customer and a third party based on agreed upon terms.

The maximum potential future payments guaranteed by the Company under 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 and six months ended June 30, 2017 and 2016.

Legal Proceedings

In the ordinary course of business, there were certain legal proceedings pending against the Company and its subsidiaries at June 30, 2017. 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 cash flows.

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 required to be measured at fair value on a recurring basis 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 June 30, 2017 and December 31, 2016.

Significant Unobservable Inputs Used in the Valuation of CDOs

	As of
	June 30, 2017				December 31, 2016
Probability of prepayment	0.0	%	-	10.9%	0.0	%	-	10.9%
Probability of default	15.6	%	-	44.1%	16.7	%	-	46.8%
Loss given default	93.3	%	-	99.2%	93.3	%	-	98.9%
Probability of deferral cure	0.0	%	-	100.0%	7.6	%	-	100.0%

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 quarterly 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 and six months ended June 30, 2017 and 2016 is presented in the following table.

MSRs

The Company services loans for others totaling $626.5 million as of June 30, 2017 and $640.5 million as of December 31, 2016. These loans are owned by third parties and are not included in the Consolidated Statements of Financial Condition. 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 June 30, 2017 and December 31, 2016.

Significant Unobservable Inputs Used in the Valuation of MSRs

	As of
	June 30, 2017				December 31, 2016
Prepayment speed	8.8	%	-	25.3%	7.7	%	-	22.8%
Maturity (months)	8		-	92	12		-	103
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 and six months ended June 30, 2017 and 2016 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.

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.

⁽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 June 30, 2017, 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, 2016, loans held-for-sale consists of 1-4 family mortgage loans, which were originated with the intent to sell, and a corporate loan.

Assets Held-for-Sale

Assets held-for-sale as of June 30, 2017 and December 31, 2016 consists of former branches that are no longer in operation and parcels of land previously purchased for expansion. These properties are being actively marketed and were transferred into the held-for-sale category at their fair value as determined by current appraisals. 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	4,470		4,470		3,416		3,416

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, 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.

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 the 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 values of senior and subordinated notes are estimated based on quoted market prices of similar instruments. The fair values of junior subordinated debentures are estimated based on quoted market prices of comparable securities when available, or by discounting the expected future cash flows at market interest rates.

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.

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 and six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

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 2016 Annual Report on Form 10-K ("2016 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 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 the FDIC Agreements. Certain loans that were previously classified as covered loans are no longer covered under the FDIC Agreements, and are included in acquired loans. 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 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 generally 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 status, 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/Loan Losses and Reserve for Unfunded Commitments

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 collateral 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 of 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 in the 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

Adopted Accounting Pronouncements

Contingent Put and Call Options in Debt Instruments: In March of 2016, the Financial Accounting Standards Board ("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. The adoption of this guidance on January 1, 2017 did not 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. The adoption of this guidance on January 1, 2017 did not 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. The adoption of this guidance on January 1, 2017 resulted in a $638,000 tax benefit to the provision for income tax expense for the six months ended June 30, 2017, recorded in the Company's results of operations. The Company elected to estimate forfeitures, which is consistent with the Company's practice before the adoption of this guidance.

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. Additional amendments to clarify the implementation guidance on the identification of performance obligations and licensing were issued in April of 2016 and narrow-scope improvements and practical expedients were issued in May of 2016.

The guidance was initially effective for annual and interim reporting periods beginning on or after December 15, 2016 but was deferred to 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. The Company's revenue is comprised of net interest income on financial assets and liabilities, which are excluded from the scope of this guidance, and noninterest income. The Company expects that this guidance will change how revenue from certain revenue streams is recognized within wealth management fees but does not expect these changes to have a significant impact on the Company's financial condition, results of operations, or liquidity. The Company continues to evaluate the impact of this guidance on other components of noninterest income. The Company will adopt this guidance on January 1, 2018, using the modified retrospective approach with a cumulative effect adjustment to opening retained earnings, if an adjustment is deemed to be significant.

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 recognize 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.

During 2016, the Company entered into a sale-leaseback transaction that resulted in a deferred gain of $82.5 million, with $78.1 million remaining as of June 30, 2017. Upon adoption of this guidance, the remaining deferred gain will be recognized immediately as a cumulative-effect adjustment to equity. For additional discussion of the sale-leaseback transaction, see Note 8 "Premises, Furniture, and Equipment." Management is evaluating the new guidance and the additional impact to the Company's financial condition, results of operations, or liquidity.

Measurement of Credit Losses on Financial Instruments: In June of 2016, the FASB issued guidance that will require entities to present financial assets measured at amortized cost at the net amount expected to be collected, considering an entity's current estimate of all expected credit losses. In addition, credit losses relating to available-for-sale debt securities will be required to be recorded through an allowance for credit losses, with changes in credit loss estimates recognized through current earnings. This guidance is effective for annual and interim periods beginning after December 15, 2019. Early adoption is permitted, but not for periods beginning before December 15, 2018. Management is evaluating the new guidance and the impact to the Company's financial condition, results of operations, and liquidity.

Classification of Certain Cash Receipts and Cash Payments: In August of 2016, the FASB issued guidance clarifying certain cash flow presentation and classification issues to reduce diversity in practice. This guidance is effective for annual and interim reporting periods beginning on or after December 15, 2017. Early adoption is permitted. Management does not expect the adoption of this guidance will materially impact the Company's Consolidated Statement of Cash Flows.

Income Taxes: In October of 2016, the FASB issued guidance that requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. 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.

Clarifying the Definition of a Business: In January of 2017, the FASB issued guidance that clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. This guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted. Management will apply this guidance to future transactions upon adoption.

Accounting for Goodwill Impairment: In January of 2017, the FASB issued guidance that simplifies the accounting for goodwill impairment for all entities. The new guidance eliminates the requirement to calculate the implied fair value of goodwill using the second step of the quantitative two-step goodwill impairment model prescribed under current accounting guidance. Under the new guidance, if a reporting unit's carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. This guidance is effective for annual and interim goodwill impairment testing dates beginning after December 15, 2019. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. Management does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity.

Presentation of Defined Benefit Retirement Plan Costs: In March of 2017, the FASB issued guidance that changes how employers that sponsor defined pension and or other postretirement benefit plans present the net periodic benefit cost in the income statement. Employers will present the service cost component of net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. Other components of net periodic benefit cost will be presented separately from the line item(s) that includes the service cost. 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.

Premium Amortization on Purchased Callable Debt Securities: In March of 2017, the FASB issued guidance that shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date. This guidance is effective for annual and interim periods beginning after December 15, 2018. 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.

Share-based Payment Award Modifications: In May of 2017, the FASB issued guidance to reduce diversity in practice by clarifying when changes to the terms or conditions of a share-based payment award must be accounted for as a modification. 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.

⁽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⁾  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 $669,000 as of June 30, 2017 and $834,000 as of December 31, 2016.
