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 nine months ended September 30, 20162017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016.2017.
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 20152016 Annual Report on Form 10-K ("20152016 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 20152016 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"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-PCInon-PCI loans.
The acquisition adjustment related to Non-PCInon-PCI loans is amortized into interest income over the contractual life of the related loans. If an acquired Non-PCInon-PCI loan is renewed subsequent to the acquisition date, any remaining acquisition adjustment is accreted into interest income and the loan is considered a new loan that is no longer classified as an acquired loan.
PCI loans are accounted for based on estimates of expected future cash flows. To estimate the fair value, the Company generally aggregates purchased consumer loans and certain smaller balance commercial loans into pools of loans with common risk characteristics, such as delinquency status, credit score, and internal risk ratings. The fair values of larger balance commercial loans are estimated on an individual basis. Expected future cash flows in excess of the fair value of loans at the purchase date ("accretable yield") are recorded as interest income over the life of the loans if the timing and amount of the expected future cash flows can be reasonably estimated. The non-accretable yield represents the difference between contractually required payments and the expected future cash flows determined at acquisition. Subsequent increases in expected future cash flows are offset against the allowance for credit losses to the extent an allowance has been established or otherwise recognized as interest income prospectively. The present value of any decreases in expected future cash flows is recognized by recording a charge-off through the allowance for loan losses or providing an allowance for loan losses.
90-Days Past Due Loans –The Company's accrual of interest on loans is 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.

Table of Contents



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-PCInon-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-PCInon-PCI allowance is based on management's evaluation of the acquired Non-PCInon-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-PCInon-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-PCInon-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

Table of Contents



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.

Equity Method Accounting: In March of 2016, the FASB issued final guidance to simplify the equity method of accounting. The guidance eliminates the presumption that a general partner should consolidate a limited partnership, affects the consolidation analysis of reporting entities that are involved with VIEs, and provides certain exceptions from consolidation guidance for certain reporting entities.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, 2015.2016. The adoption of this guidance on January 1, 20162017 did not materially impact the Company's financial condition, results of operations, or liquidity.
Simplifying the Presentation of Debt Issuance Costs:Accounting for Employee Share-based Payments: In AprilMarch of 2015,2016, the FASB issued guidance to clarifysimplify the presentationaccounting for employee share-based payment transactions.

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. In August of 2015, the FASB issued guidance that defers the effective date by one year.

Any changes in fair value will be recognized in net income unless the investments qualify for a new practicability exception.

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.

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."

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.

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 September 30, 20162017 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 September 30, 20162017 reflect changes in market activity for these securities.

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 14,16, "Fair Value."

These amounts include acquisition adjustments which resulted in a discount of $1.8 million to GLST II and $2.4 million to GLST III as of September 30, 2016 and $1.9 million to GLST II and $2.5 million to GLST III as of December 31, 2015.
(2)
The interest rates are a variable rate based on the three-month LIBOR plus 1.400% and 1.700% for GLST II and GLST III, respectively.
On April 1, 2016, $38.5 millionTable of 5.850% subordinated notes matured and were repaid by the Company. On November 22, 2016, $115.0 million of 5.875% senior notes will mature.
Issuance of Subordinated Notes
On September 29, 2016, the Company completed the issuance and sale of $150.0 million aggregate principal amount of its 5.875% subordinated notes due 2026. Interest on the notes is payable semi-annually on March 29 and September 29, beginning on March 29, 2017. The Company received proceeds of $146.5 million, net of underwriting discounts and commissions and issuance costs. The Company expects to use the net proceeds to repay at maturity the entire $115.0 million aggregate principal amount outstanding of its 5.875% senior notes due November 22, 2016, plus accrued interest, and for other general corporate purposes.
Junior Subordinated Debentures
FMCT, GLST II, and GLST III are Delaware statutory business trusts. These trusts were established for the purpose of issuing trust-preferred securities and lending the proceeds to the Company in return for junior subordinated debentures of the Company. The junior subordinated debentures are the sole assets of each trust. Therefore, each trust's ability to pay amounts due on the trust-preferred securities is solely dependent on the Company making payments on the related junior subordinated debentures. The trust-preferred securities are subject to mandatory redemption, in whole or in part, on repayment of the junior subordinated debentures at the stated maturity date or on redemption. The Company guarantees payments of distributions and redemptions on the trust-preferred securities on a limited basis.
Trust-preferred securities are included in Tier 1 capital of the Company for regulatory capital purposes. The statutory trusts qualify as VIEs for which the Company is not the primary beneficiary. Consequently, the accounts of those entities are not consolidated in the Company's financial statements.

12.14. 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.

Cash Flow Hedges
As of September 30, 2016,2017, the Company hedged $710.0$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 $710.0$980.0 million of borrowed funds using forward starting interest rate swaps through which the Company receives variable amounts and pays fixed

33




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 $325.0$415.0 million began on various dates between June of 2015 and JuneFebruary of 2016,2017, and mature between June of 2019 and AugustFebruary of 2019.2020. The remaining forward starting interest rate swaps totaling $565.0 million begin at various dates between February of 20172018 and MayFebruary of 20182020 and mature between February of 2020 and MayApril of 2020.2022. The weighted-average fixed interest rate to be paid on these interest rate swaps that have not yet begun was 1.96% as of September 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 regression analysis at the inception of the hedge relationship and on an ongoing basis. For the quarters and nine months ended September 30, 20162017 and 2015,2016, there were no material gains or losses related to cash flow hedge ineffectiveness. As of September 30, 2016,2017, the Company estimates that $3.7 million$581,000 will be reclassified from accumulated other comprehensive loss as an increasea 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 transactionstransaction with third parties.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 September 30, 20162017 and December 31, 2015,2016, the Company's credit exposure was fully secured by the underlying collateral on customer loans and mitigated through netting arrangements with third parties,third-parties, therefore, no CVA was recorded. Transaction feesCapital market products income related to commercial customer derivative instruments of $2.9$2.6 million and $8.2$6.2 million were recorded in noninterest income for the quarter and nine months ended September 30, 2016,2017, respectively. There were $1.2$2.9 million and $2.7$8.2 million of transaction feescapital market products income recorded for the quarter and nine months ended September 30, 2015,2016, respectively.

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 September 30, 20162017 and December 31, 2015.2016. 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

34




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 September 30, 20162017 and December 31, 2015,2016, 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 September 30, 20162017 and December 31, 2015.2016.

As of September 30, 20162017 and December 31, 2015,2016, 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 September 30, 20162017 and December 31, 20152016 the Company was in compliance with these provisions.

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.customers for the full contractual amount. 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 partythird-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-performingearly payment default 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 nine months ended September 30, 20162017 and 2015.2016.
Legal Proceedings
In the ordinary course of business, there were certain legal proceedings pending against the Company and its subsidiaries at September 30, 2016.2017. 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.

14.16. 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.

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 September 30, 20162017 and December 31, 2015.2016.
Significant Unobservable Inputs Used in the Valuation of CDOs
 As of As of
 September 30, 2016 December 31, 2015 September 30, 2017 December 31, 2016
Probability of prepayment 1.8% -15.0% 1.8% -15.1% 0.0% -11.4% 0.0% -10.9%
Probability of default 17.4% -49.0% 19.1% -32.6% 16.5% -44.8% 16.7% -46.8%
Loss given default 93.1% -98.5% 93.8% -97.1% 93.4% -99.2% 93.3% -98.9%
Probability of deferral cure 17.3% -100.0% 15.2% -63.1% 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 semi-annualquarterly 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 nine months ended September 30, 20162017 and 20152016 is presented in the following table.

MSRs
The Company services loans for others totaling $630.7$616.7 million as of September 30, 20162017 and $242.9$640.5 million as of December 31, 2015. As of September 30, 2016, loans serviced for others includes approximately $318.5 million of loans, the servicing of which transitioned from NI Bancshares to the Company as a result of the acquisition.2016. These loans are owned by third parties and are not included in the Consolidated Statements of Financial Condition. Additional information regarding the NI Bancshares transaction is presented in Note 3, "Acquisitions."
The Company determines the fair value of MSRs by estimating the present value of expected future cash flows associated with the mortgage loans being serviced and classifies them in level 3 of the fair value hierarchy. The following table presents the ranges of significant, unobservable inputs used by the Company to determine the fair value of MSRs as of September 30, 2017 and December 31, 2016.
Significant Unobservable Inputs Used in the Valuation of MSRs

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 nine months ended September 30, 20162017 and 20152016 is presented in the following table.

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.

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 September 30, 2016,2017, 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, 2015,2016, loans held-for-sale consists of 1-4 family mortgage loans, which were originated with the intent to sell, and a commercial real estatecorporate loan.
Assets Held-for-Sale
Assets held-for-sale as of September 30, 20162017 and December 31, 20152016 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, covered loans, and the allowance for loan losses. The fair value of loans is estimated using the present value of the expected future cash flows of the remaining maturities of the loans. Prepayment assumptions that consider the Company's historical experience and current economic and lending conditions were included. The discount rate was based on the LIBOR yield curve with adjustments for liquidity and credit risk inherent in the loans.
The fair value of the covered loan portfolio is determined by discounting the expected future cash flows at a market interest rate, which is derived from LIBOR swap rates over the life of those loans. The expected future cash flows are derived from the contractual terms of the covered loans, net of any projected credit losses. For valuation purposes, these loans are placed into groups with similar characteristics and risk factors, where appropriate. The timing and amount of credit losses for each group are estimated using historical default and loss experience, current collateral valuations, borrower credit scores, and internal risk ratings. For individually significant loans or credit relationships, the estimated fair value is determined by a specific loan level review utilizing appraised values for collateral and projections of the timing and amount of expected future cash flows.


42




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 valuevalues of senior and subordinated debt is determined usingnotes are estimated based on quoted market prices.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, as well as northwest Indiana, central and western Illinois, and eastern Iowa through 110 banking locations.Iowa. Our principal subsidiary is First Midwest Bank, which provides a broad range of banking,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 nine months ended September 30, 20162017 and 20152016 and Consolidated Statements of Financial Condition as of September 30, 20162017 and December 31, 2015.2016. 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 20152016 Annual Report on Form 10-K ("20152016 10-K"). The results of operations for the quarter and nine months ended September 30, 20162017 are not necessarily indicative of future results.
Our results of operations are affected by various factors, many of which are beyond our control, including interest rates, local and national economic conditions, business spending, consumer confidence, legislative and regulatory changes, certain seasonal factors, and changes in real estate and securities markets. Our management evaluates performance using a variety of qualitative and quantitative metrics. The primary quantitative metrics used by management include:
Net Interest Income - Net interest income, our primary source of revenue, equals the difference between interest income and fees earned on interest-earning assets and interest expense incurred on interest-bearing liabilities.
Net Interest Margin - Net interest margin equals tax-equivalent net interest income divided by total average interest-earning assets.
Noninterest Income - Noninterest income is the income we earn from fee-based revenues, investment in bank-owned life insurance ("BOLI"), other income, and non-operating revenues.
Noninterest Expense - Noninterest expense is the expense we incur to operate the Company, which includes salaries and employee benefits, net occupancy and equipment, professional services, and other costs.
Asset Quality - Asset quality represents an estimation of the quality of our loan portfolio, including an assessment of the credit risk related to existing and potential loss exposure, and can be evaluated using a number of quantitative measures, such as non-performing loans to total loans.
Regulatory Capital - Our regulatory capital is classified in one of the following tiers: (i) Common Equity Tier 1 capital ("CET1"), which consists of common equity and retained earnings, less goodwill and other intangible assets and a portion of disallowed deferred tax assets, (ii) Tier 1 capital, which consists of CET1 and qualifying trust-preferred securities and the remaining portion of disallowed deferred tax assets, and (iii) Tier 2 capital, which includes qualifying subordinated debt and the allowance for credit losses, subject to limitations.
In addition, someSome 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 following 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 March 31, 2016, both the Company and the Bank exceeded $10.0 billion in total assets. As of September 30, 2016,2017, the Company and the Bank each had total assets of approximately $11.6over $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 are not immediately subject to these additional requirements when they exceed $10 billion in assets; instead, the Company and the Bank will be subject to these various requirements over various dates. For a discussion of the impact that the Dodd-Frank Act and its implementing regulations will have on the Company and the Bank now that they have each exceeded $10.0 billion in total consolidated assets, see the "Supervision and Regulation" section in Item 1, "Business" and Item 1A, "Risk Factors" in the Company's 2015 10-K.2016 10-K, as well as our subsequent filings made with the Securities and Exchange Commission ("SEC").

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q may contain certain "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. In some cases, forward-looking statements can be identified by the use of words such as "may," "might," "will," "would," "should," "could," "expect," "plan," "intend," "anticipate," "believe," "estimate," "predict," "probable," "potential," "possible," "target," "continue," "look forward," 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, including First Midwest's proposed acquisition of Standard Bancshares, Inc., 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 20152016 10-K, as well as our subsequent filings made with the Securities and Exchange Commission ("SEC").SEC. However, these risks and uncertainties are not exhaustive. Other sections of this report describe additional factors that could adversely impact our business and financial performance.
NON-GAAP FINANCIAL INFORMATION AND RECONCILIATIONSCRITICAL ACCOUNTING ESTIMATES
The Company's accounting and reporting policies conform toOur consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and are consistent with 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") and the efficiency ratio, excluding certain significant transactions, tax-equivalent net interest income (including its individual components), tax-equivalent net interest margin, 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, and return on average tangible common equity, excluding certain significant transactions.
The Company presents earnings per share, excluding certain significant transactions, and the efficiency ratio, both of which exclude acquisition and integration related expenses and the net gain on the sale-leaseback transaction. Management believes excluding these significant transactions from earnings per share and the efficiency ratio 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.
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 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.
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.

CRITICAL ACCOUNTING ESTIMATES
Our accounting and reporting policies conform to GAAP and general practices within the banking industry. Application of GAAP requires management to make estimates, assumptions, and judgments based on information available as of the date of the financial statements that affect the amounts reported in the financial statements and accompanying notes. Critical accounting estimates are those estimates that management believes are the most important to our financial position and results of operations. Future changes in information may impact these estimates, assumptions, and judgments, which may have a material effect on the amounts reported in the financial statements.
For additional information regarding critical accounting estimates, see the "Summary of Significant Accounting Policies," presented in Note 1 to the Consolidated Financial Statements and the section titled "Critical Accounting Estimates" in Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Company's 20152016 10-K.

On September 27, 2016, the Bank completed a sale-leaseback transaction, whereby the Bank sold to Oak Street Real Estate Capital, LLC ("Oak Street") for an aggregate cash purchase price of $150.3 million, 55 properties owned and operated by the Bank as branches. Upon the sale of the branches to Oak Street, the Bank concurrently entered into triple net lease agreements with certain affiliates of Oak Street 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, of which $5.5 million was immediately recognized in earnings with the remaining $82.5 million to be accreted into income on a straight-line basis over the initial terms of the leases.

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."

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 ofincluded in our 20152016 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 September 30, 20162017 and 2015,2016, 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 nine months ended September 30, 20162017 and 2015.2016.

Non-accrual loans, including covered loans, which totaled $65.2 million as of September 30, 2017 and $44.3 million as of September 30, 2016, and $33.6 million as of September 30, 2015, are included in loans for purposes of this analysis. Additional detail regarding non-accrual loans is presented in the following section of this Item 2 titled "Non-performing Assets and Corporate Performing Potential Problem Loans."

Net interest income increased by 31.8% and 34.8% compared to the Condensed Consolidated Financial Statements" in Part I, Item 1 of this Form 10-Q.
Total average interest-earning assets for the third quarter and first nine months of 2016, increased by $1.4 billion and $1.1 billion, respectively, compared to the same periods in 2015. The increase compared to both prior periods presented was driven primarily by organic loan growth and security purchases, as well as $528.8 million of interest-earning assets acquired in the NI Bancshares transaction late in the first quarter of 2016, and $96.2 million of interest-earning assets acquired in the Peoples transaction late in the fourth quarter of 2015.
For the third quarter and first nine months of 2016, total average funding sources increased by $1.3 billion and $1.0 billion, respectively, compared to the same periods in 2015. Compared to both prior periods, the increase resulted primarily from deposits acquired in the NI Bancshares and Peoples transactions and the addition of $515.1 million of FHLB advances during the first nine months of 2016.

53




Tax-equivalent net interest margin for the third quarter and first nine months of 2016 was 3.60% and 3.66%, respectively, increasing 2 basis points from the third quarter of 2015 and decreasing 4 basis points from the first nine months of 2015. Compared to the third quarter of 2015, the increase in tax-equivalent net interest margin was driven by higher accretion on acquired loans and the maturity of $38.5 million of subordinated notes early in the second quarter of 2016, which were partially offset by the continued shift in the loan mix to floating rate loans. The decrease in net interest margin compared to the first nine months of 2015 was due primarily to the continued shift in the loan mix to floating rate loans and lower covered loan income, partially offset by the reinvestment of other interest-earning assets into higher yielding securities and loans.
Net interest income increased by 16.8% and 12.0% from the third quarter and first nine months of 2015, respectively. Compared to both prior periods, the increase in net interest income was driven primarily by organic loan growth and the acquisition of interest-earning assets and acquired loan accretion from the NI BancsharesStandard transaction early in the first quarter of 2017. Higher interest rates and Peoples transactions.loan growth also contributed to the increase in net interest income compared to both prior periods.

Acquired loan accretion contributed $3.8$7.6 million and $9.1$27.7 million to net interest income for the third quarter and first nine months of 2016,2017, respectively, and $1.8higher than $4.6 million and $7.7$11.9 million for the same periods in 2015.2016.
Tax-equivalent net interest margin for the third quarter and first nine months of 2017 was 3.86% and 3.88%, increasing by 26 and 22 basis points from the same periods in 2016. The rise in tax-equivalent net interest margin was impacted by a 6 and 14 basis point increase in acquired loan accretion compared to the third quarter and first nine months of 2016, respectively, combined with the positive impact of higher interest rates. In addition, compared to the first nine 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 $2.2 billion and $2.6 billion from the third quarter and first nine 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 nine months of 2016.
Compared to the third quarter and first nine months of 2016, total average funding sources increased by $2.1 billion and $2.4 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 nine months of 2016.

Card-based fees were negatively impacted by the reduction in interchange revenue as the Durbin Amendment of the Dodd-Frank Act ("Durbin") became effective in the third quarter of 2017. The decline in merchant servicing fees reflected lower customer volumes, virtually offset by the decline in merchant card expense included in noninterest expense for each period presented. The decline in capital market products income compared to both prior periods was consistent with loan production during the same periods.

Compared to both prior periods, the increase in total noninterest expense increased by 9.9% and 8.9%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 nine 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. 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 promotions expense compared to the first nine 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. In addition, other expenses increased compared to both prior periods due to a reduction in the reserve for unfunded commitments during the third quarter of 2016.
Acquisition and integration related expenses for the third quarter and first nine months of 2015, respectively. Operating costs associated with2017 resulted from the NI Bancsharesacquisitions of Standard and Peoples transactions accounted for slightly more than half of the increase from both periods. In addition, compensation costs associated with merit increases and investments in additional talent and systems to support organizational growth contributed to the rise compared to both prior periods.
Net OREO expense decreased compared to both prior periods due to reduced valuation adjustments and lower operating expenses. Compared toPremier during the first nine monthsquarter of 2015, these reductions were partially offset by net losses on sales of OREO properties realized during2017.

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 inCompared to both prior periods, total income tax expense and the effective tax rate were impacted by the net benefit of an increase in Illinois tax rates in the third quarter quarter of 2017, which included a $2.8 million deferred tax asset benefit, partly offset by an increase in state income tax expense. Excluding these items, the effective tax rate for the quarter and nine months ended September 30, 2016 compared2017 would have been consistent with prior periods.
There have been recent legislative proposals to reduce the same periods in 2015 resulted primarily from higher levels ofstatutory federal income subject to tax at statutory rates and an increaserate. While there can be no assurance that a reduction will ultimately occur, any such reduction in the state effectivestatutory federal income tax rate.rate would impact the carrying value of our net deferred tax assets with a corresponding charge to income tax expense.

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.

56




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.

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.

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 were 4.00was 4.27 years and 3.24%3.35%, respectively, as of September 30, 2016 compared to 3.762017, consistent with 4.27 years and 3.39%down from 3.72% as of December 31, 2015.2016. The increase in average lifedecrease resulted primarily from purchasesmaturities and sales of $824.9investment securities that were reinvested into lower-duration CMOs and MBSs.
Realized Gains and Losses
There were $3.2 million inand $3.5 million of net securities duringgains recognized for the third quarter and first nine months of 2016. The2017, on securities purchaseswith carrying values of $193.1 million and $223.8 million, respectively. Third quarter of 2017 gains were primarilythe result of the opportunistic repositioning of the securities portfolio in lower-duration CMOslight of current market conditions, including gains on the sale of three CDOs with carrying values totaling $1.9 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 MBS relative to their average lives, which droveresulted in no gains or losses as they were recorded at fair value upon acquisition. No impairment charges were recognized during the decrease in effective duration.
Realized Gains and Lossesthird quarter or first nine months of 2017.
Net securities gains for the third quarter and first nine months of 2016 were $187,000 and $1.1 million, respectively, on securities with carrying values of $2.6 million and $41.7 million for the same periods. No impairment charges were recognized during the third quarter andor first nine months of 2016.
Net securities gains for the third quarter and first nine months of 2015 were $524,000 and $1.6 million, respectively, on securities with carrying values of $9.4 million and $55.7 million for the same periods. No impairment charges were recognized during the third quarter and first nine months of 2015.
Unrealized Gains and Losses
Unrealized gains and losses on securities available-for-sale represent the difference between the aggregate cost and fair value of the portfolio. These amounts are presented in the Consolidated Statements of Comprehensive Income and reported as a separate component of stockholders' equity in accumulated other comprehensive loss on an after-tax basis. This balance sheet component will fluctuate as current market interest rates and conditions change and affect the aggregate fair value of the portfolio. Lower market rates resulted in a shift from a $17.5 millionAs of September 30, 2017, net unrealized loss positionlosses totaled $30.5 million compared to net unrealized losses of $38.1 million as of December 31, 2015 to a $3.1 million net unrealized gain position as of September 30, 2016.

Net unrealized losses in the CMO portfolio totaled $12.5 million as of September 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 September 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 $16.0$15.0 million as of September 30, 20162017 and $16.8$14.4 million as of December 31, 2015.2016. We do not believe the unrealized losses on the CDOs as of September 30, 20162017 represent other-than-temporary securities impairmentOTTI 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 1416 of "Notes to the Condensed Consolidated Financial Statements," in Part I, Item 1 of this Form 10-Q.
LOAN PORTFOLIO AND CREDIT QUALITY
Portfolio Composition
Our loan portfolio is comprised of both corporate and consumer loans with corporate loans representing 83.2%81.9% of total loans at September 30, 2016.2017. 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 currentpotential and potentialcurrent risks in the portfolio.

Commercial, Industrial, and Agricultural Loans
Commercial, industrial, and agricultural loans represent 39.9%37.5% of total loans, and totaled $3.3$3.9 billion at September 30, 2016,2017, an increase of $346.8$683.2 million, or 11.9%21.2%, from December 31, 2015. Loans acquired in the NI Bancshares transaction during the first quarter of 2016 contributed $61.3 million to the increase.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.

Consumer loans represent 16.5%18.1% of total loans, and totaled $1.4$1.9 billion at September 30, 2016,2017, an increase of $206.5$471.7 million, or 18.0%33.5%, from December 31, 2015. Loans acquired in the NI Bancshares transaction during the first quarter of 2016 contributed $64.1 million to the increase.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.

Due to the impact of protection provided by the loss share agreementsPCI loans with the FDIC that substantially mitigate the risk of loss, covered loans and covered OREO are separated in this table. Past due covered loans in the table above are determined by borrower performance compared to contractual terms, butan accretable yield are considered accruing loans since they continue to performcurrent and are not included in accordance with our expectations of cash flows. For a discussion of covered loans, see Note 1 and Note 6 of "Notes to the Condensed Consolidated Financial Statements" in Part I, Item 1 of this Form 10-Q.past due loan totals.

Non-accrual loans increased by $14.9 million from December 31, 2015, due primarily to the downgradeTable of four corporate loan relationships to non-accrual status during the first nine months of 2016, for which management is adequately collateralized. These downgrades were partially offset by charge-offs, payments, and transfers to OREO.Contents



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 restructuresrestructured loans remain classified as TDRs for the remaining term of thethese 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.

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.

Corporate performing potential problem loans were 5.1%3.6% of corporate loans at September 30, 2016, higher2017, lower than 4.4% at December 31, 2015, resulting from higher commercial and industrial and agricultural2016. The Standard acquisition added corporate performing potential problem loans classified as special mention and substandard. The rise in commercial and industrial loans classified as special mention and substandard was due primarily to operating pressures as a result of lower sales unique to certain unrelated borrowers within various industries. Within the agricultural portfolio, cash flows that were weakened due to lower grain commodity prices drove the increase in loans classifieddesignated as special mention and substandard. Management has specific monitoring and remediation plans associated with these loans.PCI.

Allowance for Credit Losses
Methodology for the Allowance for Credit Losses
The allowance for credit losses is comprised of the allowance for loan losses and the reserve for unfunded commitments and is maintained by management at a level believed adequate to absorb estimated losses inherent in the existing loan portfolio. Determination of the allowance for credit losses is inherently subjective since it requires significant estimates and management judgment, including the amounts and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans, and consideration of current economic trends.
Acquired loans are recorded at fair value, which incorporates credit risk, at the date of acquisition. No allowance for credit losses is recorded on the acquisition date. As the acquisition adjustment is accreted into income over future periods, an allowance for credit losses is established as necessary to reflect credit deterioration. In addition, certain acquired loans that have renewed subsequent to their respective acquisition dates are no longer classified as acquired loans. Instead, they are included with our loan population that is allocated an allowance in accordance with our allowance for loan losses methodology.

While management utilizes its best judgment and information available, the ultimate adequacy of the allowance for credit losses depends on a variety of factors beyond the Company's control, including the performance of its loan portfolio, the economy, changes in interest rates and property values, and the interpretation of loan risk ratings by regulatory authorities. Management believes that the allowance for credit losses is an appropriate estimate of credit losses inherent in the loan portfolio as of September 30, 2016.2017.
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 September 30, 20162017 and December 31, 2015.2016.

The remaining acquisition adjustment consists of $11.2$45.8 million and $13.4$32.5 million relating to purchased credit impaired ("PCI")PCI and non-purchased credit impaired ("Non-PCI") loans, respectively, as of September 30, 2016,2017, and $8.5$10.8 million and $9.2$11.8 million relating to PCI and Non-PCI loans, respectively, as of December 31, 2015.2016.
(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 1.13%1.09% as of September 30, 2016.2017. The acquisition adjustment increased by $7.0$55.7 million during the first nine months of 2016,2017, driven primarily by the NI BancsharesStandard transaction. This was partially offset by acquired loan accretion, which is included in interest income, resulting in a remaining acquisition adjustment as a percent of acquired loans of 3.48%4.31%. Acquired loans that are renewed at market terms are no longer classified as acquired loans. These loans totaled $101.5$304.0 million and $117.6 million as of September 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 $2.3$2.8 million on acquired loans.

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.

Total average funding sources for the third quarter of 20162017 increased by 15.9%$2.1 billion, or 21.5%, compared to the fourth quarter of 20152016 and 15.2%$2.1 billion, or 20.9%, compared to the third quarter of 2015.2016. The rise in average core deposits compared to the both prior periods resulted primarily from the full quarter impact of$1.7 billion in core deposits assumed in the Peoples and NI Bancshares transactions andStandard transaction, as well as organic growth. Compared to the fourth quarter of 2015, the increase in average core deposits was impacted by the seasonal increase in average municipal deposits. The addition in FHLB advances of $515.1 million during 2016 contributed to the increase in average borrowed funds compared to both prior periods presented.
On April 1, 2016, $38.5 million in 5.850% subordinated notes matured and were repaid by the Company. On September 29, 2016, the Company completed the issuance and sale of $150.0 million aggregate principal amount of its 5.875% subordinated notes due 2026. The Company received proceeds of $146.5 million, net of underwriting discounts and commissions and issuance costs. The Company expects to use the net proceeds to repay at maturity the entire $115.0 million aggregate principal amount outstanding of its 5.875% senior notes due November 22, 2016, plus accrued interest, and for other general corporate purposes.

Average borrowed funds totaled $457.1$644.8 million for the first nine months of 20162017, increasing by $311.5$187.7 million compared to the same period in 2015.2016. This increase was due primarily to the increase inhigher levels of FHLB advances of $515.1 million during the first nine months of 2016.2017. The weighted-average rate on FHLB advances for the third quarter of 2016both periods presented was impacted by the hedging of $415.0 million and $325.0 million ofin FHLB advances as of September 30, 2017 and 2016, respectively, using interest rate swaps through which the Company receives variable amounts and pays fixed amounts. TheseThe weighted-average interest rate paid on these interest rate swaps have a weighted-average interest rate ofwas 2.17% and 2.19% as of September 30, 2016. The remaining $200.0 million of FHLB advances have a fixed interest rate of 0.40%.2017 and 2016, respectively. For a detailed discussion of interest rate swaps, see Note 1214 of "Notes to the Condensed Consolidated Financial Statements" in Part I, Item 1 of this Form 10-Q.
On September 27, 2016, the Company entered into a loan agreement with U.S. Bank National Association providing for a $50.0 million short-term, unsecured revolving credit facility. On September 26, 2017, the Company entered into a first amendment to this credit facility, which extends the maturity to September 26, 2018. Advances will bear interest at a rate equal to one-month LIBOR plus 1.75%, adjusted on a monthly basis, and the Company must pay an unused facility fee equal to 0.35% per annum on a quarterly basis. As of September 30, 2016,2017, no amount was outstanding under the facility.
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 20152016 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

The Company's total capital and Tier 1 capital to risk-weighted assets was 12.25% as of September 30, 2016, increasingratios decreased compared to December 31, 2016 due primarily to the issuance of $150.0 million of subordinated notes during the third quarter of 2016. The decrease in the Company's other regulatory capital ratios from December 31, 2015 resulted from the addition of risk-weightedStandard and average assets, including goodwill and other intangible assets, related to the NI Bancshares acquisition. These declinesPremier acquisitions, which were partiallypartly offset by an increase in retained earnings andover the $54.9 millionfirst nine months of common stock issued as consideration for the NI Bancshares acquisition.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 related expenses (all periods presented) and a net gain related to a sale-leaseback transaction (third quarter of 2016). 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 20152016 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 September 30, 20162017 and December 31, 2015,2016, 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, 49%50% of the loan portfolio consisted of fixed rate loans and 51%50% were floating rate loans as of September 30, 2016,2017, compared to 54%48% and 46%52%, respectively, as of December 31, 2015.2016.
As of September 30, 2016,2017, investments, consisting of securities and interest-bearing deposits in other banks, are more heavily weighted toward fixed rate securities at 85%88% of the total compared to 15%12% for floating rate interest-bearing deposits in other banks. This compares to investments comprising 84%95% of fixed rate securities and 16%5% of floating rate interest-bearing deposits in other banks as of December 31, 2015.2016. 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 $376.9$96.0 million, or 8%2%, of the floating rate loan portfolio as of September 30, 2016,2017, compared to $374.5$271.5 million, or 10%5%, of the floating rate loan portfolio as of December 31, 2015.2016. On the liability side of the balance sheet, 86% of deposits as of both September 30, 20162017 and December 31, 20152016 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.

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 September 30, 20162017 would increase net interest income by $35.2$47.0 million, or 10.2%, over the next twelve months compared to no change in interest rates. This same measure was $28.0$25.4 million, or 8.9%7.1%, as of December 31, 2015.2016.
Overall, positive interest rate risk volatility as of September 30, 20162017 increased compared to December 31, 2015,2016. This increase was driven primarily by organica 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 issuance of fixed-rate subordinated notes. These increases were partially offset by the NI Bancshares acquisition which added term securities and fixed rate loans.
