Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation – The accompanying unaudited condensed consolidated interim financial statements of First Midwest Bancorp, Inc. (the “Company”), a Delaware corporation, were prepared in accordance with the rules and regulations of the 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 nine-month periods ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.
	The accounting and reporting policies of the Company and its subsidiaries conform to U.S. generally accepted accounting principles (“GAAP”) and general practices within the banking industry. The accompanying quarterly statements do not include certain information and footnote disclosures required by GAAP for complete annual financial statements. Therefore, these financial statements should be read in conjunction with the Company’s 2012 Annual Report on Form 10-K (“2012 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 Company owns interests in certain variable interest entities (“VIEs”) as described in Note 21, “Variable Interest Entities,” in the Company’s 2012 10-K. A VIE is a partnership, limited liability company, trust, or other legal entity that does not have sufficient equity to finance its activities without additional subordinated financial support from other parties, or whose investors lack the characteristics associated with owning a controlling financial interest. The VIEs are not consolidated in the Company’s financial statements since the Company is not the primary beneficiary of any of the VIEs.
	The accounting policies related to loans, the allowance for credit losses, the FDIC indemnification asset, and derivative financial instruments are presented below. For a summary of all other significant accounting policies, please refer to Note 1, “Summary of Significant Accounting Policies,” in the Company’s 2012 10-K.
	Loans – Loans held-for-investment are loans that the Company intends to hold until they are paid in full and are carried at the principal amount outstanding, including certain net deferred loan origination fees. Interest income on loans is accrued based on principal amounts outstanding. Loan origination fees, commitment fees, and certain direct loan origination costs are deferred, and the net amount is amortized as a yield adjustment over the contractual life of the related loans or commitments and included in interest income. Fees related to standby letters of credit are amortized into fee income over the contractual life of the commitment. Other credit-related fees are recognized as fee income when earned. Loans held-for-sale are carried at the lower of aggregate cost or fair value and included in other assets in the Consolidated Statements of Financial Condition.
	Purchased Impaired Loans – Purchased impaired loans are recorded at fair value on the acquisition date and are accounted for prospectively based on estimates of expected cash flows. No allowance for credit losses is recorded on these loans at the acquisition date. To estimate the fair value, the Company generally aggregates purchased consumer loans and certain smaller balance commercial loans into pools of loans with common risk characteristics, such as delinquency status, credit score, and internal risk rating. The fair values of larger balance commercial loans are estimated on an individual basis. Expected future cash flows in excess of the fair value of loans at the purchase date (“accretable yield”) are recorded as interest income over the life of the loans if the timing and amount of the future cash flows can be reasonably estimated. The non-accretable yield represents the difference between contractually required payments and the cash flows expected to be collected at acquisition.
	Subsequent increases in cash flows are recognized as interest income prospectively. The present value of any decreases in expected cash flows is recognized by recording a charge-off through the allowance for loan and covered loan losses or establishing an allowance for loan and covered loan losses.
	Non-accrual Loans – Generally, corporate loans are placed on non-accrual status (i) when either principal or interest payments become 90 days or more past due based on contractual terms unless the loan is sufficiently collateralized such that full repayment of both principal and interest is expected and is in the process of collection within a reasonable period or (ii) when an individual analysis of a borrower’s creditworthiness indicates a credit should be placed on non-accrual status whether or not the loan is 90 days or more past due. When a loan is placed on non-accrual status, unpaid interest credited to income in the current year is reversed, and unpaid interest accrued in prior years is charged against the allowance for loan losses. After the loan is placed on non-accrual, all debt service payments are applied to the principal on the loan. Future interest income may only be recorded on a cash basis after recovery of principal is reasonably assured. Non-accrual loans are returned to accrual status when the financial position of the borrower and other relevant factors indicate that the Company will collect all principal and interest.
	Commercial loans and loans secured by real estate are charged-off when deemed uncollectible. A loss is recorded if the net realizable value of the underlying collateral is less than the outstanding principal and interest. Consumer loans that are not secured by real estate are subject to mandatory charge-off at a specified delinquency date and are usually not classified as non-accrual prior to being charged-off. Closed-end consumer loans, which include installment, automobile, and single payment loans, are usually charged-off no later than the end of the month in which the loan becomes 120 days past due.
	Purchased impaired loans are generally considered accruing loans unless reasonable estimates of the timing and amount of future cash flows cannot be determined. Loans without reasonable cash flow estimates are classified as non-accrual loans, and interest income is not recognized on those loans until the timing and amount of the future cash flows can be reasonably determined.
	Troubled Debt Restructurings (“TDRs”) – A restructuring is considered a TDR when (i) the borrower is experiencing financial difficulties and (ii) the creditor grants a concession, such as forgiveness of principal, reduction of the interest rate, changes in payments, or extension of the maturity date. Loans are not classified as TDRs when the modification is short-term or results in an insignificant delay in payments. The Company’s TDRs are determined on a case-by-case basis.
	The Company does not accrue interest on a TDR unless it believes collection of all principal and interest under the modified terms is reasonably assured. For a TDR to begin accruing interest, the borrower must demonstrate both some level of past performance and the future capacity to perform under the modified terms. Generally, six months of consecutive payment performance under the restructured terms is required before a TDR is returned to accrual status. However, the period could vary depending on the individual facts and circumstances of the loan. An evaluation of the borrower’s current creditworthiness is used to assess the borrower’s capacity to repay the loan under the modified terms. This evaluation includes an estimate of expected cash flows, evidence of strong financial position, and estimates of the value of collateral, if applicable. However, these TDRs continue to be separately reported as restructured until after the calendar year in which the restructuring occurred. 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 based on current information and events. 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. After a loan is designated as impaired, all debt service payments are applied to the principal of the loan. Future interest income may only be recorded on a cash basis after recovery of principal is reasonably assured.
	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. All impaired loans are included in non-performing assets. Purchased impaired loans are not reported as impaired loans provided that estimates of the timing and amount of future cash flows can be reasonably determined.
	90-Days Past Due Loans –The Company’s accrual of interest on loans is discontinued at the time the loan is 90 days past due unless the credit is sufficiently collateralized and in the process of renewal or collection.
	Allowance for Credit Losses – The allowance for credit losses is comprised of the allowance for loan losses, the allowance for covered loan losses, and the reserve for unfunded commitments, and is maintained by management at a level believed adequate to absorb estimated losses inherent in the existing loan portfolio. Determination of the allowance for credit losses is subjective since it requires significant estimates and management judgment, including the amounts and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans, consideration of current economic trends, and other factors.
	Loans deemed to be uncollectible are charged-off against the allowance for loan and covered loan losses, while recoveries of amounts previously charged-off are credited to the allowance for loan and covered loan losses. Additions to the allowance for loan and covered loan losses are charged to expense through the provision for loan and covered loan losses. The amount of provision depends on a number of factors, including net charge-off levels, loan growth, changes in the composition of the loan portfolio, and the Company’s assessment of the allowance for loan and covered loan losses based on the methodology discussed below.
	Allowance for Loan Losses – The allowance for loan losses consists of (i) specific reserves established for probable losses on 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) the impact of other internal and external qualitative factors.
	The specific reserves component of the allowance for loan losses is based on a periodic analysis of impaired loans exceeding a fixed dollar amount. If the value of an impaired loan is less than the recorded book value, the Company either establishes a valuation allowance (i.e., a specific reserve) equal to the excess of the book value over the value of the loan as a component of the allowance for loan losses or charges off the amount if it is a confirmed loss.
	The general reserve component is based on a loss migration analysis, which examines actual loss experience for a rolling 8-quarter period by loan category and the related internal risk rating for corporate loans. The loss migration analysis is updated quarterly using actual loss experience. This component is then adjusted based on management’s consideration of many internal and external qualitative factors, including:
	•	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.
	Allowance for Covered Loan Losses – The Company’s allowance for covered loan losses reflects the difference between the carrying value and the discounted present value of the estimated cash flows of the covered purchased impaired loans. On a periodic basis, the adequacy of this allowance is determined through a re-estimation of cash flows on all of the outstanding covered purchased impaired loans using either a probability of default/loss given default (“PD/LGD”) methodology or a specific review methodology. The PD/LGD model is an expected loss model that estimates future cash flows using a probability of default curve and loss given default estimates.
	Reserve for Unfunded Commitments – The Company also maintains a reserve for unfunded commitments, including letters of credit, for the risk of loss inherent in these arrangements. The reserve for unfunded commitments is estimated using the loss migration analysis from the allowance for loan losses, adjusted for probabilities of future funding requirements. The reserve for unfunded commitments is included in other liabilities in the Consolidated Statements of Financial Condition.
	The establishment of the allowance for credit losses involves a high degree of judgment given the difficulty of assessing the factors impacting loan repayment and estimating the timing and amount of losses. While management utilizes its best judgment and information available, the adequacy of the allowance for credit losses depends on a variety of factors beyond the Company’s control, including the performance of its loan portfolio, the economy, changes in interest rates and property values, and the interpretation of loan risk classifications by regulatory authorities.
	FDIC Indemnification Asset – The majority of loans and OREO acquired through FDIC-assisted transactions are covered by loss share agreements with the FDIC (the “FDIC Agreements”), under which the FDIC reimburses the Company for the majority of the losses and eligible expenses related to these assets. The FDIC indemnification asset represents the present value of future expected reimbursements from the FDIC. Since the indemnified items are covered loans and covered OREO, which are initially measured at fair value, the FDIC indemnification asset is also initially measured at fair value by discounting the cash flows expected to be received from the FDIC. These cash flows are estimated by multiplying estimated losses on purchased impaired loans and OREO by the reimbursement rates in the FDIC Agreements.
	The balance of the FDIC indemnification asset is adjusted periodically to reflect changes in estimated cash flows. Decreases in expected cash flows on the indemnification asset are recorded prospectively through amortization and increases in estimated reimbursements from the FDIC are recognized by an increase in the carrying value of the indemnification asset. Payments from the FDIC for reimbursement of losses result in a reduction of the FDIC indemnification asset.
	Derivative Financial Instruments – In the ordinary course of business, the Company enters into derivative transactions as part of its overall interest rate risk management strategy to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. All derivative instruments are recorded at fair value as either other assets or other liabilities in the Consolidated Statements of Financial Condition. Subsequent changes in a derivative’s fair value are recognized in earnings unless specific hedge accounting criteria are met.
	On the date the Company enters into a derivative contract, the derivative is designated as a fair value hedge, a cash flow hedge, or a non-hedge derivative instrument. Fair value hedges are designed to mitigate exposure to changes in the fair value of an asset or liability attributable to a particular risk, such as interest rate risk. Cash flow hedges are designed to mitigate exposure to variability in expected future cash flows to be received or paid related to an asset, liability, or other type of forecasted transaction. The Company formally documents all relationships between hedging instruments and hedged items, including its risk management objective and strategy for undertaking each hedge transaction.
	At the hedge’s inception and quarterly thereafter, a formal assessment is performed to determine the effectiveness of the derivative in offsetting changes in the fair values or cash flows of the hedged items in the current period and prospectively. If a derivative instrument designated as a hedge is terminated or ceases to be highly effective, hedge accounting is discontinued prospectively, and the gain or loss is amortized into earnings. For fair value hedges, the gain or loss is amortized over the remaining life of the hedged asset or liability. For cash flow hedges, the gain or loss is amortized over the same period that the forecasted hedged transactions impact earnings. If the hedged item is disposed of, any fair value adjustments are included in the gain or loss from the disposition of the hedged item. If the forecasted transaction is no longer probable, the gain or loss is included in earnings immediately.
	For effective fair value hedges, changes in the fair value of the derivative instruments, as well as changes in the fair value of the hedged item, are recognized in earnings. For cash flow hedges, the effective portion of the change in fair value of the derivative instrument is reported as a component of accumulated other comprehensive loss. The unrealized gain or loss is reclassified into earnings in the same period the hedged transaction affects earnings.
	Ineffectiveness is calculated based on the change in fair value of the hedged item compared with the change in fair value of the hedging instrument. For all types of hedges, any ineffectiveness in the hedging relationship is recognized in earnings during the period the ineffectiveness occurs.

Recent Accounting Pronouncements	'
	RECENT ACCOUNTING PRONOUNCEMENTS
	Balance Sheet – Disclosures about Offsetting Assets and Liabilities: In December of 2011, the FASB issued guidance on the presentation of offsetting assets and liabilities on the balance sheet, which was further clarified in January 2013. This guidance requires an entity to disclose both the gross information and net information regarding instruments and transactions eligible for offset, such as derivatives, sale and repurchase agreements, and securities borrowing and lending arrangements. The statement was effective for annual and interim periods beginning on or after January 1, 2013. The Company’s derivative assets and liabilities are presented gross, rather than net, in the Consolidated Statements of Financial Condition. The adoption of this guidance on January 1, 2013 did not impact the Company’s financial condition, results of operations, or liquidity.
	Technical Corrections and Improvements: In October of 2012, the FASB issued guidance to update the Accounting Standards Codification (the “Codification”) on a variety of topics, which include source literature amendments, guidance clarification and reference corrections, and relocated guidance. In addition, the standard includes amendments to conform terminology and clarifies certain fair value guidance in the Codification. Amendments that do not have transition guidance were effective immediately, and amendments subject to transition guidance were effective for fiscal periods beginning after December 15, 2012. The adoption of this guidance on January 1, 2013 did not materially impact the Company’s financial condition, results of operations, or liquidity.
	Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income: In February of 2013, the FASB issued guidance to improve the reporting of reclassifications out of accumulated other comprehensive income. The amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component on either the face of the income statement or as a separate disclosure in the notes to the financial statements. This guidance was effective for fiscal periods beginning after December 15, 2012. The Company provides disclosures related to amounts reclassified out of accumulated other comprehensive income in Note 3, “Securities.” Since this guidance only impacted the placement of certain disclosures in the financial statements, the adoption of this guidance on January 1, 2013 did not impact the Company’s financial condition, results of operations, or liquidity.

	SECURITIES
	Securities are generally classified as held-to-maturity, trading, or available-for-sale at the time of purchase. Securities classified as held-to-maturity are securities for which management has the positive intent and ability to hold to maturity and are stated at cost.
	The Company’s trading securities consist of diversified investment securities reported at fair value that are held in a grantor trust under deferred compensation arrangements that allow plan participants to direct amounts into a variety of securities, including Company stock. Net trading gains represent changes in the fair value of the trading securities portfolio and are included in other noninterest income in the Condensed Consolidated Statements of Income.
	All other securities are classified as available-for-sale and are carried at fair value with unrealized gains and losses, net of related deferred income taxes, recorded in stockholders’ equity as a separate component of accumulated other comprehensive loss.

Net gains realized on securities for the third quarter and nine months ended September 30, 2013 were $34.2 million and $34.4 million, respectively. During the third quarter of 2013, the Company sold its investment in an equity security which resulted in a $34.2 million gain.
The non-cash impairment charges in the table above relate to OTTI charges on municipal securities and CDOs. 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. In deriving the credit component of the impairment on the CDOs, projected cash flows were discounted at the contractual rate and compared to the fair values computed by discounting future projected cash flows at the London Interbank Offered Rate (“LIBOR”) plus an adjustment to reflect the higher risk inherent in these securities given their complex structures and the impact of market factors.

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 remaining individual unrealized loss as of September 30, 2013 represents an OTTI attributable to credit quality. In addition, the Company does not intend to sell the securities with unrealized losses, 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 September 30, 2013 reflect the illiquidity of these structured investment vehicles. Management does not believe these unrealized losses represent OTTI related to credit deterioration. In addition, the Company does not intend to sell the CDOs with unrealized losses within a short period of time, and the Company does not believe it is more likely than not that it will be required to sell them before recovery of their amortized cost basis, which may be at maturity.
Significant judgment is required to calculate the fair value of the CDOs, all of which are pooled. The Company estimates the fair value of these securities using a discounted cash flow analysis with the assistance of a structured credit valuation firm. For additional discussion of the CDO valuation methodology, refer to Note 12, “Fair Value.”

	The Company primarily lends to small and mid-sized businesses, commercial real estate customers, and consumers in the Company’s markets. Within these areas, the Company diversifies its loan portfolio by loan type, industry, and borrower.
	It is the Company’s policy to review each prospective credit to determine the appropriateness and the adequacy of security or collateral prior to making a loan. In the event of borrower default, the Company seeks recovery in compliance with state lending laws, the Company’s lending standards, and credit monitoring and remediation procedures. A discussion of risk characteristics relevant to each portfolio segment is presented in Note 4, “Loans,” in the Company’s 2012 10-K.
	Mortgage Loan Sales
	During the quarter ended September 30, 2013, the Company sold $36.1 million of mortgage loans at a gain of $1.0 million, which is included in mortgage banking income in the Consolidated Statements of Income. For the nine months ended September 30, 2013, a gain of $4.0 million was recognized on $118.1 million of mortgage loans sold. The Company retained servicing responsibilities for the sold mortgages and collects servicing fees equal to a percentage of the outstanding principal balance.
	The Company also retained limited recourse for credit losses on the sold loans. A description of the recourse obligation is presented in Note 11, “Commitments, Guarantees, and Contingent Liabilities.”

Acquired Loans	'
	ACQUIRED LOANS
	Since 2009, the Company acquired the majority of the assets and assumed the deposits of four financial institutions in FDIC-assisted transactions. In three of those transactions, most loans and OREO acquired are covered by the FDIC Agreements. The significant accounting policies related to purchased impaired loans and the related FDIC indemnification asset are presented in Note 1, “Summary of Significant Accounting Policies.”

	(1)	At acquisition, the Company made an election to account for certain covered loans as purchased impaired loans. These loans totaled $25.5 million at September 30, 2013 and $28.1 million at December 31, 2012.
	(2)	These loans did not meet the criteria to be accounted for as purchased impaired loans at acquisition.
	Except for leases and revolving loans, management determined that a significant portion of the acquired loans had evidence of credit deterioration since origination (“purchased impaired loans”), and it was probable at the date of acquisition that the Company would not collect all contractually required principal and interest payments. Evidence of credit quality deterioration was evaluated using various indicators, such as past due and non-accrual status. Other key considerations and indicators included the past performance of the troubled institutions’ credit underwriting standards, completeness and accuracy of credit files, maintenance of risk ratings, and age of appraisals.
	In connection with the FDIC Agreements, the Company recorded an indemnification asset. To maintain eligibility for the loss share reimbursement, the Company is required to follow certain servicing procedures as specified in the FDIC Agreements. The Company is in compliance with those requirements as of September 30, 2013 and December 31, 2012.

For TDRs to be removed from TDR status, 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 loan terms. TDRs that were returned to performing status totaled $5.0 million and $16.6 million for the nine months ended September 30, 2013 and 2012, respectively. No TDRs were returned to performing status for the quarters ended September 30, 2013 and 2012. 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 commitments to lend additional funds to borrowers with TDRs as of September 30, 2013 or December 31, 2012.
Credit Quality Indicators
Corporate loans and commitments are assessed for credit risk and assigned ratings based on various characteristics, such as the borrower’s cash flow, leverage, and collateral. Ratings for commercial credits are reviewed periodically. On a quarterly basis, consumer loans are assessed for credit quality based on the accrual status of the loan.

	Effective income tax rate	46		%	43.3		%	39.5		%	50.6		%
	Federal income tax expense and the related effective income tax rate are influenced primarily by the amount of tax-exempt income derived from investment securities and bank-owned life insurance in relation to pre-tax income and state income taxes. State income tax expense and the related effective income 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.
	Income tax expense was $25.0 million and $39.2 million for the third quarter and nine months ended September 30, 2013, respectively, compared to an income tax benefit of $37.0 million and $35.1 million for the same periods in 2012. The rise in income tax expense in 2013 was driven primarily by higher levels of income during 2013, which are subject to tax at statutory rates, and to a non-deductible BOLI modification loss recorded during the third quarter of 2013. Excluding the BOLI modification loss, the effective tax rate would have been 36.9% and 34.8% for the third quarter and nine months ended September 30, 2013, respectively.

	EMPLOYEE BENEFIT PLANS
	The Company sponsors a defined contribution retirement savings plan (the “Profit Sharing Plan”) and a noncontributory defined benefit retirement plan (the “Pension Plan”) that cover eligible employees. Additional information regarding the Profit Sharing Plan and Pension Plan can be found in Note 15, “Employee Benefit Plans,” in the Company’s 2012 10-K.
	The Pension Plan covers employees who met certain eligibility requirements and were hired before April 1, 2007, the date it was amended to eliminate enrollment of new participants. During the second quarter of 2013, the Board of Directors approved an amendment to freeze benefit accruals under the Pension Plan effective on January 1, 2014. As a result of the Pension Plan amendment, the Company recorded an immaterial curtailment loss and remeasured the Pension Plan obligations and assets as of June 30, 2013. The remeasurement decreased the projected pension obligation by $11.0 million and increased other comprehensive income by $6.5 million, after tax. Depending on various factors, these actions could reduce 2013 pension expense by approximately $1.0 million.

Derivative Financial Instruments	'
	DERIVATIVE FINANCIAL INSTRUMENTS

	(1)	No other collateral was required to be pledged.
	(2)	This amount represents the fair value of assets needed to settle derivative transactions if credit risk related contingent factors were triggered.
	Hedge ineffectiveness is recognized in other noninterest income in the Consolidated Statements of Income. For the quarters and nine months ended September 30, 2013 and 2012, gains or losses relating to fair value hedge ineffectiveness were not material.
	The Company also enters into derivative transactions with its commercial customers and simultaneously enters into an offsetting interest rate derivative transaction with a third-party. This transaction allows the Company’s customers to effectively convert a variable rate loan into a fixed rate loan. Due to the offsetting nature of these transactions, the Company does not apply hedge accounting treatment. Transaction fees related to commercial customer derivative instruments of $1.4 million and $2.0 million were recorded in noninterest income for the quarter and nine months ended September 30, 2013, respectively. There were no transaction fees recorded for the quarter and nine months ended September 30, 2012.

	(1)	No other collateral was required to be pledged.
	(2)	This amount represents the fair value if credit risk related contingent factors were triggered.
	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. At September 30, 2013, 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.
	As of September 30, 2013 and December 31, 2012, 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 September 30, 2013 and December 31, 2012, the Company was not in violation of these provisions.
	The Company’s derivative portfolio also includes other derivative instruments that do not receive hedge accounting treatment consisting of commitments to originate 1-4 family mortgage loans and foreign exchange contracts. In addition, 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 period presented. The Company had no other derivative instruments as of September 30, 2013 or December 31, 2012. The Company does not enter into derivative transactions for purely speculative purposes.

	(1)	Federal regulations regarding electronic fund transfers require customers to affirmatively consent to the institution’s overdraft service for automated teller machine and one-time debit card transactions before overdraft fees may be assessed on the account. Customers are provided a specific line for the amount they may overdraw.
	(2)	Included in other liabilities in the Consolidated Statements of Financial Condition.
	(3)	The Company amortizes these amounts into income over the commitment period.
	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 and its loans and minimizes exposure to credit loss through various collateral requirements.
	Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby letters of credit generally are contingent on the failure of the customer to perform according to the terms of the contract with the third party and are often issued in favor of a municipality where construction is taking place to ensure the borrower adequately completes the construction.
	The maximum potential future payments guaranteed by the Company under standby letters of credit arrangements are equal to the contractual amount of the commitment. If a commitment is funded, the Company may seek recourse through the liquidation of the underlying collateral including real estate, production plants and property, marketable securities, or receipt of cash.
	As a result of the sale of certain 1-4 family mortgage loans, the Company is contractually obligated to repurchase any non-performing loans or loans that do not meet underwriting requirements at recorded value. In accordance with the sales agreements, there is no limitation on the maximum potential future payments or expiration of the Company’s recourse obligation. No loans were required to be repurchased during the quarters and nine months ended September 30, 2013 or 2012.
	During 2012, the Company entered into two forward commitments with the FHLB of Chicago to borrow $250 million for a five year period beginning in 2014 at a weighted average interest rate of 2.0%. The Company terminated these forward commitments during the third quarter of 2013, resulting in a gain of $7.8 million recorded in noninterest income in the Condensed Consolidated Statement of Income.
	Legal Proceedings
	In 2011, the Bank was named in a purported class action lawsuit filed in the Circuit Court of Cook County, Illinois on behalf of certain of the Bank’s customers who incurred overdraft fees. The lawsuit is based on the Bank’s practices relating to debit card transactions, and alleges that these practices resulted in customers being assessed excessive overdraft fees. The plaintiffs seek an unspecified amount of damages and other relief, including restitution. No class has been certified. The Bank filed a motion to dismiss the plaintiffs’ complaint and, on January 23, 2013, the Circuit Court entered an order granting the Bank’s motion and dismissed the complaint with prejudice. The plaintiffs have appealed the Circuit Court’s ruling, and the appeal is currently pending with the Appellate Court of Illinois. The Company continues to believe that the Bank has meritorious defenses to the claims made by the plaintiffs.
	There are certain other legal proceedings pending against the Company and its subsidiaries in the ordinary course of business. The Company does not believe that liabilities, individually or in the aggregate, arising from any legal proceedings, if any, would have a material adverse effect on the consolidated financial condition of the Company as of September 30, 2013.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	FAIR VALUE
	Fair value represents the amount 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. Refer to the “Fair Value Measurements of Other Financial Instruments” section of this footnote. Any aggregation of the estimated fair values presented in this footnote does not represent the value of the Company.
	Depending on the nature of the asset or liability, the Company uses various valuation methodologies and assumptions to estimate fair value. GAAP provides a three-tiered fair value hierarchy based on the inputs used to measure fair value. The hierarchy is defined as follows:
	•	Level 1 – Quoted prices in active markets for identical assets or liabilities.
	•	Level 2 – Observable inputs other than level 1 prices, such as quoted prices for similar instruments, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
	•	Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These inputs require significant management judgment or estimation, some of which use model-based techniques and may be internally developed.
	Assets and liabilities are assigned to a level within the fair value hierarchy based on the lowest level of significant input used to measure fair value. Assets and liabilities may change levels within the fair value hierarchy due to market conditions or other circumstances. Those transfers are recognized on the date of the event that prompted the transfer. There were no transfers of assets or liabilities between levels of the fair value hierarchy during the periods presented.
	Assets and Liabilities Required to be Measured at Fair Value on a Recurring Basis
	The following table provides the fair value for assets and liabilities required to be measured at fair value on a recurring basis in the Consolidated Statements of Financial Condition by level in the fair value hierarchy.

	The following sections describe the specific valuation techniques and inputs used to measure financial assets and liabilities at fair value.
	Trading Securities
	The Company’s trading securities consist of diversified investment securities held in a grantor trust and are invested in money market and mutual funds. The fair value of these money market and mutual funds is based on quoted market prices in active exchange markets and is classified in level 1 of the fair value hierarchy. Changes in the fair value of trading securities are included in other noninterest income in the Condensed Consolidated Statements of Income.
	Securities Available-for-Sale
	Where quoted prices are available in an active market, securities are classified in level 1 of the fair value hierarchy. The Company’s available-for-sale securities are primarily fixed income instruments that are not quoted on an exchange, but may be traded in active markets. The fair values 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. Quarterly, the Company evaluates the methodologies used by its external pricing services to develop the fair values to determine whether the results of the valuations are representative of an exit price in the Company’s principal markets and an appropriate representation of fair value.
	The Company’s hedge fund investment is classified in level 2 of the fair value hierarchy. The fair value is derived from monthly and annual financial statements provided by hedge fund management. The majority of the hedge fund’s investment portfolio is held in securities that are freely tradable and are listed on national securities exchanges.
	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 relies on credit analysis and review of historical financial data for each of the issuers of the securities underlying the individual CDO (the “Issuers”) to estimate the cash flows. These estimates are highly subjective and sensitive to several significant, unobservable inputs, including prepayment assumptions, default probabilities, loss given default assumptions, and deferral cure probabilities. The cash flows for each Issuer are then discounted to present values using LIBOR plus an adjustment to reflect the higher risk inherent in these securities given their complex structures and 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. Information for each CDO, as well as the significant unobservable assumptions, is presented in the following table.

(1)	Represents actual deferrals and defaults, net of recoveries, as a percent of the original collateral.
(2)	Represents expected future net deferrals and defaults, net of recoveries, as a percent of the remaining performing collateral. The probability of future defaults is derived for each Issuer based on a credit analysis. The associated assumed loss given default is based on historical default and recovery information provided by a nationally recognized credit rating agency and is assumed to be 90% for banks, 85% for insurance companies, and 100% for Issuers that have already defaulted.
(3)	Represents additional defaults that the CDO can absorb before the security experiences any credit impairment. The excess subordination percentage is calculated by dividing the amount of potential additional loss that can be absorbed (before the receipt of all expected future principal and interest payments is affected) by the total balance of performing collateral.
(4)	Cash flows are discounted at LIBOR plus this adjustment to reflect the higher risk inherent in these securities.
Most Issuers have the right to prepay its 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 its 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. Management also reviews market activity for the same or similar tranches of the CDOs, when available. 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 nine months ended September 30, 2013 and 2012 is presented in the following table.

(3)	There were no purchases, issuances, or settlements of CDOs during the periods presented. One CDO with a carrying value of zero was sold during the nine months ended September 30, 2013, resulting in a gain of $101,000.
Mortgage Servicing Rights
The Company services loans for others totaling $202.5 million as of September 30, 2013 and $109.7 million as of December 31, 2012. These loans are owned by third parties and are not included in the Consolidated Statements of Condition. The Company estimates the fair value of mortgage servicing rights by using a discounted cash flow analysis and classifies them in level 3 of the fair value hierarchy. Additional information regarding the Company’s mortgage servicing rights can be found in Note 22, “Fair Value,” in the Company’s 2012 10-K.
Derivative Assets and Derivative Liabilities
The Company enters into interest rate swaps that are executed in the dealer market, and pricing is based on market quotes obtained from the counterparty. 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. The Company also enters into derivative transactions with commercial customers and simultaneously enters into an offsetting interest rate derivative transaction with a third party, which are valued using market consensus prices.
Pension Plan Assets
Although pension plan assets are not consolidated in the Company’s Consolidated Statements of Financial Condition, the fair value of pension plan assets is required to be measured on an annual basis. Additionally, pension plan assets were remeasured as of June 30, 2013 as a result of the amendment to freeze the benefit accruals under the Pension Plan. Refer to Note 9, “Employee Benefit Plans” for additional discussion regarding this change. The fair value of pension plan assets is presented in the following table by level in the fair value hierarchy.

Mutual funds, certain U.S. government agency securities, and common stocks are based on quoted market prices in active exchange markets and classified in level 1 of the fair value hierarchy. Corporate bonds, certain U.S. government agency, and U.S. Treasury securities are valued at quoted prices from independent sources that are based on observable market trades or observable prices for similar bonds where a price for the identical bond is not observable and, therefore, are classified as level 2 of the fair value hierarchy. Common trust funds are valued at quoted redemption values on the last business day of the Plan’s year end and are classified as level 2 in the fair value hierarchy.
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.

(1)	Includes OREO and covered OREO with fair value adjustments subsequent to initial transfer.
(2)	Included in other assets in the Consolidated Statements of Financial Condition.
(3)	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 loans 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% -20%. 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. Any valuation adjustments for reductions in the fair value of OREO are recognized in the Company’s operating results in the period in which they occur.
Loans Held-for-Sale
As of September 30, 2013, loans held-for-sale consisted of 1-4 family mortgage loans. The Company had no loans held-for-sale as of December 31, 2012.
Assets Held-for-Sale
As of September 30, 2013, assets held-for-sale consisted of three former bank branches that are no longer in operation, which were transferred into the held-for-sale category at their recorded investment as an approximation of fair value. Therefore, 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, and other short-term investments, accrued interest receivable, and accrued interest payable.
Securities Held-to-Maturity - The fair value of securities held-to-maturity is based on quoted market prices or dealer quotes. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities.
FHLB and Federal Reserve Bank Stock - The carrying amounts approximate fair value.
Net Loans - Net loans includes loans, covered loans, and the allowance for loans and covered loan losses. The fair value of loans is estimated using the present value of the 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. The primary impact of credit risk on the fair value of the loan portfolio was accommodated through the use of the allowance for loan and covered loan losses, which is believed to represent the current fair value of estimated inherent losses for purposes of the fair value calculation.
The fair value of the covered loan portfolio is determined by discounting the estimated cash flows at a market interest rate, which is derived from LIBOR swap rates over the life of those loans. The estimated cash flows are determined using the contractual terms of the covered loans, net of any projected credit losses. For valuation purposes, these loans are placed into groups with similar characteristics and risk factors, where appropriate. The timing and amount of credit losses for each group are estimated using historical default and loss experience, current collateral valuations, borrower credit scores, and internal risk ratings. For individually significant loans or credit relationships, the estimated fair value is determined by a specific loan level review utilizing appraised values for collateral and projections of the timing and amount of cash flows.
FDIC Indemnification Asset - The fair value of the FDIC indemnification asset is calculated by discounting the cash flows expected to be received from the FDIC. The future cash flows are estimated by multiplying expected losses on covered loans and covered OREO by the reimbursement rates in the FDIC Agreements.
Investment in BOLI - The fair value of BOLI approximates the carrying amount as both are based on each policy’s respective CSV, which is the amount the Company would receive upon 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 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 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 repurchase agreements 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 federal funds purchased, repurchase agreements, federal term auction facilities, and other borrowed funds approximate their fair value due to their short-term nature.
Senior and Subordinated Debt - The fair value of senior and subordinated debt was determined using quoted market prices.
Standby Letters of Credit - The fair value of standby letters of credit represents deferred fees arising from the related off-balance sheet financial instruments. These deferred fees approximate the fair value of these instruments and are based on several factors, including the remaining terms of the agreements and the credit standing of the customers.
Commitments - The Company estimated the fair value of commitments outstanding to be immaterial based on the following factors: (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 of First Midwest Bancorp, Inc. (the “Company”), a Delaware corporation, were prepared in accordance with the rules and regulations of the 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 nine-month periods ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.
	The accounting and reporting policies of the Company and its subsidiaries conform to U.S. generally accepted accounting principles (“GAAP”) and general practices within the banking industry. The accompanying quarterly statements do not include certain information and footnote disclosures required by GAAP for complete annual financial statements. Therefore, these financial statements should be read in conjunction with the Company’s 2012 Annual Report on Form 10-K (“2012 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	'
	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.
	The Company owns interests in certain variable interest entities (“VIEs”) as described in Note 21, “Variable Interest Entities,” in the Company’s 2012 10-K. A VIE is a partnership, limited liability company, trust, or other legal entity that does not have sufficient equity to finance its activities without additional subordinated financial support from other parties, or whose investors lack the characteristics associated with owning a controlling financial interest. The VIEs are not consolidated in the Company’s financial statements since the Company is not the primary beneficiary of any of the VIEs.
	The accounting policies related to loans, the allowance for credit losses, the FDIC indemnification asset, and derivative financial instruments are presented below. For a summary of all other significant accounting policies, please refer to Note 1, “Summary of Significant Accounting Policies,” in the Company’s 2012 10-K.
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. Interest income on loans is accrued based on principal amounts outstanding. Loan origination fees, commitment fees, and certain direct loan origination costs are deferred, and the net amount is amortized as a yield adjustment over the contractual life of the related loans or commitments and included in interest income. Fees related to standby letters of credit are amortized into fee income over the contractual life of the commitment. Other credit-related fees are recognized as fee income when earned. Loans held-for-sale are carried at the lower of aggregate cost or fair value and included in other assets in the Consolidated Statements of Financial Condition.
Purchased Impaired Loans	'
	Purchased Impaired Loans – Purchased impaired loans are recorded at fair value on the acquisition date and are accounted for prospectively based on estimates of expected cash flows. No allowance for credit losses is recorded on these loans at the acquisition date. To estimate the fair value, the Company generally aggregates purchased consumer loans and certain smaller balance commercial loans into pools of loans with common risk characteristics, such as delinquency status, credit score, and internal risk rating. The fair values of larger balance commercial loans are estimated on an individual basis. Expected future cash flows in excess of the fair value of loans at the purchase date (“accretable yield”) are recorded as interest income over the life of the loans if the timing and amount of the future cash flows can be reasonably estimated. The non-accretable yield represents the difference between contractually required payments and the cash flows expected to be collected at acquisition.
	Subsequent increases in cash flows are recognized as interest income prospectively. The present value of any decreases in expected cash flows is recognized by recording a charge-off through the allowance for loan and covered loan losses or establishing an allowance for loan and covered loan losses.
Non-accrual Loans	'
	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 based on contractual terms unless the loan is sufficiently collateralized such that full repayment of both principal and interest is expected and is in the process of collection within a reasonable period or (ii) when an individual analysis of a borrower’s creditworthiness indicates a credit should be placed on non-accrual status whether or not the loan is 90 days or more past due. When a loan is placed on non-accrual status, unpaid interest credited to income in the current year is reversed, and unpaid interest accrued in prior years is charged against the allowance for loan losses. After the loan is placed on non-accrual, all debt service payments are applied to the principal on the loan. Future interest income may only be recorded on a cash basis after recovery of principal is reasonably assured. Non-accrual loans are returned to accrual status when the financial position of the borrower and other relevant factors indicate that the Company will collect all principal and interest.
	Commercial loans and loans secured by real estate are charged-off when deemed uncollectible. A loss is recorded if the net realizable value of the underlying collateral is less than the outstanding principal and interest. Consumer loans that are not secured by real estate are subject to mandatory charge-off at a specified delinquency date and are usually not classified as non-accrual prior to being charged-off. Closed-end consumer loans, which include installment, automobile, and single payment loans, are usually charged-off no later than the end of the month in which the loan becomes 120 days past due.
	Purchased impaired loans are generally considered accruing loans unless reasonable estimates of the timing and amount of future cash flows cannot be determined. Loans without reasonable cash flow estimates are classified as non-accrual loans, and interest income is not recognized on those loans until the timing and amount of the future cash flows can be reasonably determined.
Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]	'
	Troubled Debt Restructurings (“TDRs”) – A restructuring is considered a TDR when (i) the borrower is experiencing financial difficulties and (ii) the creditor grants a concession, such as forgiveness of principal, reduction of the interest rate, changes in payments, or extension of the maturity date. Loans are not classified as TDRs when the modification is short-term or results in an insignificant delay in payments. The Company’s TDRs are determined on a case-by-case basis.
	The Company does not accrue interest on a TDR unless it believes collection of all principal and interest under the modified terms is reasonably assured. For a TDR to begin accruing interest, the borrower must demonstrate both some level of past performance and the future capacity to perform under the modified terms. Generally, six months of consecutive payment performance under the restructured terms is required before a TDR is returned to accrual status. However, the period could vary depending on the individual facts and circumstances of the loan. An evaluation of the borrower’s current creditworthiness is used to assess the borrower’s capacity to repay the loan under the modified terms. This evaluation includes an estimate of expected cash flows, evidence of strong financial position, and estimates of the value of collateral, if applicable. However, these TDRs continue to be separately reported as restructured until after the calendar year in which the restructuring occurred. 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 based on current information and events. 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. After a loan is designated as impaired, all debt service payments are applied to the principal of the loan. Future interest income may only be recorded on a cash basis after recovery of principal is reasonably assured.
90-Days Past Due Loans	'
	90-Days Past Due Loans –The Company’s accrual of interest on loans is discontinued at the time the loan is 90 days past due unless the credit is sufficiently collateralized and in the process of renewal or collection.
Allowance for Credit Losses	'
	Allowance for Credit Losses – The allowance for credit losses is comprised of the allowance for loan losses, the allowance for covered loan losses, and the reserve for unfunded commitments, and is maintained by management at a level believed adequate to absorb estimated losses inherent in the existing loan portfolio. Determination of the allowance for credit losses is subjective since it requires significant estimates and management judgment, including the amounts and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans, consideration of current economic trends, and other factors.
	Loans deemed to be uncollectible are charged-off against the allowance for loan and covered loan losses, while recoveries of amounts previously charged-off are credited to the allowance for loan and covered loan losses. Additions to the allowance for loan and covered loan losses are charged to expense through the provision for loan and covered loan losses. The amount of provision depends on a number of factors, including net charge-off levels, loan growth, changes in the composition of the loan portfolio, and the Company’s assessment of the allowance for loan and covered loan losses based on the methodology discussed below.
	Allowance for Loan Losses – The allowance for loan losses consists of (i) specific reserves established for probable losses on 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) the impact of other internal and external qualitative factors.
	The specific reserves component of the allowance for loan losses is based on a periodic analysis of impaired loans exceeding a fixed dollar amount. If the value of an impaired loan is less than the recorded book value, the Company either establishes a valuation allowance (i.e., a specific reserve) equal to the excess of the book value over the value of the loan as a component of the allowance for loan losses or charges off the amount if it is a confirmed loss.
	The general reserve component is based on a loss migration analysis, which examines actual loss experience for a rolling 8-quarter period by loan category and the related internal risk rating for corporate loans. The loss migration analysis is updated quarterly using actual loss experience. This component is then adjusted based on management’s consideration of many internal and external qualitative factors, including:
	•	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.
	Allowance for Covered Loan Losses – The Company’s allowance for covered loan losses reflects the difference between the carrying value and the discounted present value of the estimated cash flows of the covered purchased impaired loans. On a periodic basis, the adequacy of this allowance is determined through a re-estimation of cash flows on all of the outstanding covered purchased impaired loans using either a probability of default/loss given default (“PD/LGD”) methodology or a specific review methodology. The PD/LGD model is an expected loss model that estimates future cash flows using a probability of default curve and loss given default estimates.
	Reserve for Unfunded Commitments – The Company also maintains a reserve for unfunded commitments, including letters of credit, for the risk of loss inherent in these arrangements. The reserve for unfunded commitments is estimated using the loss migration analysis from the allowance for loan losses, adjusted for probabilities of future funding requirements. The reserve for unfunded commitments is included in other liabilities in the Consolidated Statements of Financial Condition.
	The establishment of the allowance for credit losses involves a high degree of judgment given the difficulty of assessing the factors impacting loan repayment and estimating the timing and amount of losses. While management utilizes its best judgment and information available, the adequacy of the allowance for credit losses depends on a variety of factors beyond the Company’s control, including the performance of its loan portfolio, the economy, changes in interest rates and property values, and the interpretation of loan risk classifications by regulatory authorities.
FDIC Indemnification Asset	'
	FDIC Indemnification Asset – The majority of loans and OREO acquired through FDIC-assisted transactions are covered by loss share agreements with the FDIC (the “FDIC Agreements”), under which the FDIC reimburses the Company for the majority of the losses and eligible expenses related to these assets. The FDIC indemnification asset represents the present value of future expected reimbursements from the FDIC. Since the indemnified items are covered loans and covered OREO, which are initially measured at fair value, the FDIC indemnification asset is also initially measured at fair value by discounting the cash flows expected to be received from the FDIC. These cash flows are estimated by multiplying estimated losses on purchased impaired loans and OREO by the reimbursement rates in the FDIC Agreements.
	The balance of the FDIC indemnification asset is adjusted periodically to reflect changes in estimated cash flows. Decreases in expected cash flows on the indemnification asset are recorded prospectively through amortization and increases in estimated reimbursements from the FDIC are recognized by an increase in the carrying value of the indemnification asset. Payments from the FDIC for reimbursement of losses result in a reduction of the FDIC indemnification asset.
Derivative Financial Instruments	'
	Derivative Financial Instruments – In the ordinary course of business, the Company enters into derivative transactions as part of its overall interest rate risk management strategy to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. All derivative instruments are recorded at fair value as either other assets or other liabilities in the Consolidated Statements of Financial Condition. Subsequent changes in a derivative’s fair value are recognized in earnings unless specific hedge accounting criteria are met.
	On the date the Company enters into a derivative contract, the derivative is designated as a fair value hedge, a cash flow hedge, or a non-hedge derivative instrument. Fair value hedges are designed to mitigate exposure to changes in the fair value of an asset or liability attributable to a particular risk, such as interest rate risk. Cash flow hedges are designed to mitigate exposure to variability in expected future cash flows to be received or paid related to an asset, liability, or other type of forecasted transaction. The Company formally documents all relationships between hedging instruments and hedged items, including its risk management objective and strategy for undertaking each hedge transaction.
	At the hedge’s inception and quarterly thereafter, a formal assessment is performed to determine the effectiveness of the derivative in offsetting changes in the fair values or cash flows of the hedged items in the current period and prospectively. If a derivative instrument designated as a hedge is terminated or ceases to be highly effective, hedge accounting is discontinued prospectively, and the gain or loss is amortized into earnings. For fair value hedges, the gain or loss is amortized over the remaining life of the hedged asset or liability. For cash flow hedges, the gain or loss is amortized over the same period that the forecasted hedged transactions impact earnings. If the hedged item is disposed of, any fair value adjustments are included in the gain or loss from the disposition of the hedged item. If the forecasted transaction is no longer probable, the gain or loss is included in earnings immediately.
	For effective fair value hedges, changes in the fair value of the derivative instruments, as well as changes in the fair value of the hedged item, are recognized in earnings. For cash flow hedges, the effective portion of the change in fair value of the derivative instrument is reported as a component of accumulated other comprehensive loss. The unrealized gain or loss is reclassified into earnings in the same period the hedged transaction affects 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.

	(1)	Represents actual deferrals and defaults, net of recoveries, as a percent of the original collateral.
	(2)	Represents expected future net deferrals and defaults, net of recoveries, as a percent of the remaining performing collateral. The probability of future defaults is derived for each Issuer based on a credit analysis. The associated assumed loss given default is based on historical default and recovery information provided by a nationally recognized credit rating agency and is assumed to be 90% for banks, 85% for insurance companies, and 100% for Issuers that have already defaulted.
	(3)	Represents additional defaults that the CDO can absorb before the security experiences any credit impairment. The excess subordination percentage is calculated by dividing the amount of potential additional loss that can be absorbed (before the receipt of all expected future principal and interest payments is affected) by the total balance of performing collateral.
	(4)	Cash flows are discounted at LIBOR plus this adjustment to reflect the higher risk inherent in these securities.

There were no purchases, issuances, or settlements of CDOs during the periods presented. One CDO with a carrying value of zero was sold during the nine months ended September 30, 2013, resulting in a gain of $101,000.

[2]

Represents actual deferrals and defaults, net of recoveries, as a percent of the original collateral.

[3]

Represents expected future net deferrals and defaults, net of recoveries, as a percent of the remaining performing collateral. The probability of future defaults is derived for each Issuer based on a credit analysis. The associated assumed loss given default is based on historical default and recovery information provided by a nationally recognized credit rating agency and is assumed to be 90% for banks, 85% for insurance companies, and 100% for Issuers that have already defaulted.

[4]

Represents additional defaults that the CDO can absorb before the security experiences any credit impairment. The excess subordination percentage is calculated by dividing the amount of potential additional loss that can be absorbed (before the receipt of all expected future principal and interest payments is affected) by the total balance of performing collateral.

[5]

Cash flows are discounted at LIBOR plus this adjustment to reflect the higher risk inherent in these securities.
