Item 1: Financial Statements Continued:

ASSOCIATED BANC-CORP

Notes to Consolidated Financial Statements

These interim consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission and, therefore, certain information and footnote disclosures normally presented in accordance with U.S. generally accepted accounting principles have been omitted or abbreviated. The information contained in the consolidated financial statements and footnotes in Associated Banc-Corp’s 2014 annual report on Form 10-K, should be referred to in connection with the reading of these unaudited interim financial statements.

NOTE 1: Basis of Presentation

In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the financial position, results of operations and comprehensive income, changes in stockholders’ equity, and cash flows of Associated Banc-Corp (individually referred to herein as the “Parent Company,” and together with all of its subsidiaries and affiliates, collectively referred to herein as the “Corporation”) for the periods presented, and all such adjustments are of a normal recurring nature. The consolidated financial statements include the accounts of all subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year.

In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ significantly from those estimates. Estimates that are particularly susceptible to significant change include the determination of the allowance for loan losses, goodwill impairment assessment, mortgage servicing rights valuation, and income taxes. Management has evaluated subsequent events for potential recognition or disclosure.

During the third quarter of 2015, the Corporation reclassified approximately $500 million of closed end first lien home equity loans to residential mortgage loans in order to better align with the Corporation's regulatory reporting of residential mortgage loan products. All prior periods have been restated to reflect this change. As a result, the restated home equity loan portfolio is $1.1 billion for December 31, 2014 , compared to the originally reported amount of $1.6 billion . Similarly, the restated residential mortgage loan portfolio is $5.1 billion for December 31, 2014 , compared to the originally reported amount of $4.5 billion .

During the fourth quarter of 2014, the Corporation changed the presentation of certain common stock repurchases included in the Consolidated Statements of Changes in Stockholders' Equity and the Consolidated Statements of Cash Flows. As a result, the common stock repurchases during the first nine months of 2014 have been reclassified to conform with this change in presentation.

NOTE 2: Acquisition

On February 17, 2015, the Corporation acquired Ahmann & Martin Co., a risk and employee benefits consulting firm based in Minnesota. The firm merged into Associated Financial Group, LLC the Corporation's insurance brokerage subsidiary. The Corporation's acquisition of Ahmann & Martin Co. enhances the Corporation's ability to offer clients unique, comprehensive solutions to meet their insurance and financial risk management needs. The transaction was valued at approximately $48 million with the opportunity to increase the consideration by $8 million should certain contingencies be met over a defined period.

The transaction was accounted for using the acquisition method of accounting and as such, assets acquired, liabilities assumed and consideration exchanged were recorded at their estimated fair value on the acquisition date. Goodwill from the acquisition represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired and is not deductible for tax purposes. As a result of the acquisition, the Corporation recorded goodwill of approximately $40 million and other intangible assets of approximately $12 million . Goodwill was assigned to the Corporation's Community, Consumer, and Business segment. See Note 8 for additional information on goodwill and other intangible assets.

NOTE 3 : New Accounting Pronouncements Adopted

In June 2015, the FASB issued a technical corrections and improvements accounting standards update which makes minor amendments to the FASB Accounting Standards Codification. The four general topics covered in the guidance include: (1) amendments related to differences between original guidance and the codification, (2) guidance clarification and reference corrections, (3) simplification, and (4) minor improvements. The amendments that require transition guidance are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The amendments that require transition guidance are not applicable to the Corporation. All other amendments were effective upon the issuance of this update in June 2015. The Corporation adopted the accounting standard during the second quarter of 2015, as required, with no material impact on its results of operations, financial position, or liquidity.

Table of Contents

In May 2015, the FASB issued an amendment to its current guidance regarding pushdown accounting for newly acquired businesses. The amendment eliminates the SEC guidance on pushdown accounting from the Accounting Standard Codification. The amendments align the FASB’s codification with the related material in the SEC's staff accounting bulletin (SAB) No. 115. SAB 115 rescinds portions of the interpretive guidance included in the SEC's Staff Accounting Bulletins series and brings existing guidance into conformity with ASU 2014-17, Pushdown Accounting, which provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. The Corporation adopted the accounting standard during the second quarter of 2015, as required, with no material impact on its results of operations, financial position, or liquidity.

In August 2014, the FASB issued an amendment to clarify how creditors are to classify certain government-guaranteed mortgage loans upon foreclosure. This amendment requires that a mortgage loan be derecognized and a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separate from the loan before foreclosure and (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under the claim and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. This amendment was effective for annual reporting periods, including interim periods within those annual periods, beginning after December 15, 2014. The Corporation adopted the accounting standard on a prospective basis during the first quarter of 2015, as required, with no material impact on its results of operations, financial position, or liquidity.

In June 2014, the FASB issued an amendment to clarify the current accounting and disclosures for certain repurchase agreements. The amendments in this update require two accounting changes: (1) change the accounting for repurchase-to-maturity transactions to secured borrowing accounting and (2) require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The amendments in this update also require additional disclosures for certain transactions on the transfer of financial assets, as well as new disclosures for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings. This amendment was effective for public business entities for the first interim or annual period beginning after December 15, 2014. The Corporation adopted the accounting standard during the first quarter of 2015, as required, with no material impact on its results of operations, financial position, or liquidity. See Note 9 for the new repurchase agreement disclosures.

In January 2014, the FASB issued an amendment to clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar agreement. In addition, the amendments require interim and annual disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure in accordance with local requirements of the applicable jurisdiction. This amendment was effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. The Corporation adopted the accounting standard using the prospective transition method during the first quarter of 2015, as required, with no material impact on its results of operations, financial position, or liquidity.

In January 2014, the FASB issued an amendment which permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). For those investments in qualified affordable housing projects not accounted for using the proportional method, the investment should be accounted for as an equity method investment or a cost method investment. The decision to apply the proportional amortization method of accounting is an accounting policy decision that should be applied consistently to all qualifying affordable housing project investments rather than a decision to be applied to individual investments. This amendment should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. This amendment was effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. The Corporation made an accounting policy election to use the proportional amortization method for investments in qualified affordable housing projects during the first quarter of 2015, which had no material impact on its results of operations, financial position, or liquidity.

NOTE 4: Earnings Per Common Share

Earnings per share are calculated utilizing the two-class method. Basic earnings per common share are calculated by dividing the sum of distributed earnings to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding. Diluted earnings per common share are calculated by dividing the sum of distributed earnings to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding adjusted for the dilutive effect of common stock instruments (outstanding stock options, unvested restricted stock, and outstanding stock warrants). Presented below are the calculations for basic and diluted earnings per common share.



	Three Months Ended September 30,						Nine Months Ended September 30,
	2015			2014			2015			2014

Diluted earnings per common share	$	0.31		$	0.31		$	0.92		$	0.85

Options to purchase approximately 1 million common shares were outstanding for both the three and nine months ended September 30, 2015 , respectively, but excluded from the calculation of diluted earnings per common share as the effect would have been anti-dilutive. Options to purchase approximately 2 million and 3 million common shares were outstanding for the three and nine months ended September 30, 2014, respectively, but excluded from the calculation of diluted earnings per common share as the effect would have been anti-dilutive.

NOTE 5: Stock-Based Compensation

At September 30, 2015 , the Corporation had one active stock-based compensation plan, the 2013 Incentive Compensation Plan. All stock options granted under this plan have an exercise price that is equal to the closing price of the Corporation’s stock on the grant date.

The Corporation also issues restricted common stock and restricted common stock units to certain key employees (collectively referred to as “restricted stock awards”) under this plan. The shares of restricted stock are restricted as to transfer, but are not restricted as to dividend payment or voting rights. Restricted stock units receive dividend equivalents but do not have voting rights. The transfer restrictions lapse over three or four years, depending upon whether the awards are service-based or performance-based. Service-based awards are contingent upon continued employment or meeting the requirements for retirement, and performance-based awards are based on earnings per share performance goals, relative total shareholder return, and continued employment or meeting the requirements for retirement. The plan provides that restricted stock awards and stock options will immediately become fully vested upon retirement from the Corporation of those colleagues whose retirement meets the early retirement or normal retirement definitions under the plan (“retirement eligible colleagues”).

Table of Contents

The fair value of stock options granted is estimated on the date of grant using a Black-Scholes option pricing model, while the fair value of restricted stock awards is their fair market value on the date of grant. The fair values of stock options and restricted stock awards are amortized as compensation expense on a straight-line basis over the vesting period of the grants. Beginning with the 2014 grants, expenses related to stock options and restricted stock awards are fully recognized on the date the colleague meets the definition of normal or early retirement. Compensation expense recognized is included in personnel expense in the consolidated statements of income.

Assumptions are used in estimating the fair value of stock options granted. The weighted average expected life of the stock option represents the period of time that stock options are expected to be outstanding and is estimated using historical data of stock option exercises and forfeitures. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility is based on the implied volatility of the Corporation’s stock. The following assumptions were used in estimating the fair value for options granted in the first nine months of 2015 and full year 2014 .



	2015		2014
Dividend yield	2.00	%	2.00	%
Risk-free interest rate	2.00	%	2.00	%
Weighted average expected volatility	20.00	%	20.00	%
Weighted average expected life	6 years		6 years
Weighted average per share fair value of options	$3.08		$3.00

The Corporation is required to estimate potential forfeitures of stock grants and adjust compensation expense recorded accordingly. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized in the period of change and will also impact the amount of stock compensation expense to be recognized in future periods.

A summary of the Corporation’s stock option activity for the year ended December 31, 2014 and for the nine months ended September 30, 2015 , is presented below.

The Corporation has the ability to issue shares from treasury or new shares upon the exercise of stock options or the granting of restricted stock awards. The Board of Directors has authorized management to repurchase shares of the Corporation’s common stock each quarter in the market, to be made available for issuance in connection with the Corporation’s employee incentive plans and for other corporate purposes. The repurchase of shares will be based on market and investment opportunities, capital levels, growth prospects, and regulatory constraints. Such repurchases may occur from time to time in open market purchases, block transactions, private transactions, accelerated share repurchase programs, or similar facilities.

During the second and third quarters of 2015, the Corporation restructured its investment portfolio and sold over $1 billion of FNMA and FHLMC mortgage-related securities and reinvested into GNMA mortgage-related securities, generating a $4 million net gain on sale. This restructuring lowered risk weighted assets and related capital requirements, while improving the liquidity of the investment portfolio. The $1.2 billion of proceeds from the sales of investment securities includes a $139 million receivable due to an unsettled trade from the sale of investment securities that occurred at the end of September.

The Corporation reviews the investment securities portfolio on a quarterly basis to monitor its exposure to other-than-temporary impairment. A determination as to whether a security’s decline in fair value is other-than-temporary takes into consideration numerous factors and the relative significance of any single factor can vary by security. Some factors the Corporation may consider in the other-than-temporary impairment analysis include, the length of time and extent to which the security has been in an unrealized loss position, changes in security ratings, financial condition and near-term prospects of the issuer, as well as security and industry specific economic conditions. The Corporation may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds, and the value of any underlying collateral for certain securities.

Based on the Corporation’s evaluation, management does not believe any unrealized loss at September 30, 2015 represents an other-than-temporary impairment as these unrealized losses are primarily attributable to changes in interest rates and the current market conditions, and not credit deterioration. The unrealized losses reported for municipal securities relate to various state and local political subdivisions and school districts. The Corporation currently does not intend to sell nor does it believe that it will

be required to sell the securities contained in the above unrealized losses table before recovery of their amortized cost basis. The improvement in the unrealized loss position of the investment securities portfolio was due to a reduction in the level of intermediate term interest rates from December 31, 2014 to September 30, 2015 . Since December 31, 2014 , the three-year and five-year U.S. Treasury note rates declined 18 basis points ("bp") and 28 bp, respectively.

Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank Stocks : The Corporation is required to maintain Federal Reserve stock and FHLB stock as a member of both the Federal Reserve System and the FHLB, and in amounts as required by these institutions. These equity securities are “restricted” in that they can only be sold back to the respective institutions or another member institution at par. Therefore, they are less liquid than other marketable equity securities and their fair value is equal to amortized cost. The Corporation had FHLB stock of $88 million and $118 million at September 30, 2015 and December 31, 2014 , respectively, and Federal Reserve Bank stock of $73 million and $71 million at September 30, 2015 and December 31, 2014 , respectively. During second quarter of 2015 , the Corporation purchased $14 million of additional FHLB stock to support the overall increase in FHLB advances and subsequently sold $43 million of excess FHLB stock.

The level of the allowance for loan losses represents management’s estimate of an amount appropriate to provide for probable credit losses in the loan portfolio at the balance sheet date. In general, the change in the allowance for loan losses is a function of a number of factors, including but not limited to changes in the loan portfolio, net charge offs, trends in past due and impaired loans, and the level of potential problem loans. Management considers the allowance for loan losses a critical accounting policy, as assessing these numerous factors involves significant judgment.

The allowance for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to unfunded credit facilities (including unfunded loan commitments and letters of credit) and is included in accrued expenses and other liabilities on the consolidated balance sheets. The determination of the appropriate level of the allowance for unfunded commitments is based upon an evaluation of the unfunded credit facilities, including an assessment of historical commitment utilization experience and credit risk grading of the loan. Net adjustments to the allowance for unfunded commitments are included in provision for credit losses in the consolidated statements of income. See Note 13 for additional information on the allowance for unfunded commitments.

The allocation methodology used by the Corporation includes allocations for specifically identified impaired loans and loss factor allocations (used for both criticized and non-criticized loan categories), with a component primarily based on historical loss rates and a component primarily based on other qualitative factors. Management allocates the allowance for loan losses by pools of risk within each loan portfolio. The allocation of the allowance for loan losses by loan portfolio is made for analytical purposes and is not necessarily indicative of the trend of future loan losses in any particular category. At September 30, 2015 , $29 million of the commercial and industrial allowance for loan losses was attributable to Oil and Gas related credits, compared to $17 million at December 31, 2014 . This allocated allowance for loan losses represented 3.83% and 2.26% of period end Oil and Gas related loans at September 30, 2015 and December 31, 2014 , respectively. The total allowance for loan losses is available to absorb losses from any segment of the loan portfolio.

Factors that are important to managing overall credit quality are sound loan underwriting and administration, systematic monitoring of existing loans and commitments, effective loan review on an ongoing basis, early identification of potential problems, and appropriate allowance for loan losses, allowance for unfunded commitments, nonaccrual and charge off policies.

For commercial loans, management has determined the pass credit quality indicator to include credits that exhibit acceptable financial statements, cash flow, and leverage. If any risk exists, it is mitigated by the loan structure, collateral, monitoring, or control. For consumer loans, performing loans include credits that are performing in accordance with the original contractual terms. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Special mention credits have potential weaknesses that deserve management’s attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the credit. Potential problem loans are considered inadequately protected by the current net worth and paying capacity of the obligor or the collateral pledged. These loans generally have a well-defined weakness, or weaknesses that may jeopardize liquidation of the debt and are characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. Lastly, management considers a loan to be impaired when it is probable that the Corporation will be unable to collect all amounts due according to the original contractual terms of the note agreement, including both principal and interest. Management has determined that commercial and consumer loan relationships that have nonaccrual status or have had their terms restructured in a troubled debt restructuring meet this impaired loan definition. Commercial loans classified as special mention, potential problem, and impaired are reviewed at a minimum on a quarterly basis, while pass rated credits are reviewed on an annual basis or more frequently if the loan renewal is less than one year or if otherwise warranted.

Table of Contents

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are generally placed on nonaccrual status when contractually past due 90 days or more as to interest or principal payments, unless the loan is well secured and in the process of collection. Additionally, whenever management becomes aware of facts or circumstances that may adversely impact the collectability of principal or interest on loans, it is management’s practice to place such loans on nonaccrual status immediately, rather than delaying such action until the loans become 90 days past due. When a loan is placed on nonaccrual status, previously accrued and uncollected interest is reversed, amortization of related deferred loan fees or costs is suspended, and income is recorded only to the extent that interest payments are subsequently received in cash and a determination has been made that the principal and interest of the loan is collectible. If collectability of the principal and interest is in doubt, payments received are applied to loan principal.

While a loan is in nonaccrual status, some or all of the cash interest payments received may be treated as interest income on a cash basis as long as the remaining recorded investment in the asset (i.e., after charge off of identified losses, if any) is deemed to be fully collectible. The determination as to the ultimate collectability of the asset’s remaining recorded investment must be supported by a current, well documented, credit evaluation of the borrower’s financial condition and prospects for repayment, including consideration of the borrower’s sustained historical repayment performance and other relevant factors. A nonaccrual loan is returned to accrual status when all delinquent principal and interest payments become current in accordance with the terms of the loan agreement, the borrower has demonstrated a period of sustained repayment performance, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. A sustained period of repayment performance generally would be a minimum of six months.

Troubled Debt Restructurings (“Restructured Loans”)

Loans are considered restructured loans if concessions have been granted to borrowers that are experiencing financial difficulty. The concessions granted generally involve the modification of terms of the loan, such as changes in payment schedule or interest rate, which generally would not otherwise be considered. Restructured loans can involve loans remaining on nonaccrual, moving to nonaccrual, or continuing on accrual status, depending on the individual facts and circumstances of the borrower. Nonaccrual restructured loans are included and treated with all other nonaccrual loans. In addition, all accruing restructured loans are reported as troubled debt restructurings, which are considered and accounted for as impaired loans. Generally, restructured loans remain on nonaccrual until the customer has attained a sustained period of repayment performance under the modified loan terms (generally a minimum of six months). However, performance prior to the restructuring, or significant events that coincide with the restructuring, are considered in assessing whether the borrower can meet the new terms and whether the loan should be returned to or maintained on accrual status. If the borrower’s ability to meet the revised payment schedule is not reasonably assured, the loan remains on nonaccrual status. The Corporation had an $18 million recorded investment in loans modified in troubled debt restructurings for the nine months ended September 30, 2015 , of which $2 million was in accrual status and $16 million was in nonaccrual pending a sustained period of repayment.

All restructured loans are disclosed as restructured loans in the calendar year of restructuring. In subsequent years, a restructured loan modified at a market rate that has performed according to the modified terms for at least six months will cease being disclosed as a restructured loan. A loan that has been modified at a below market rate will return to performing status if it satisfies the six month performance requirement; however, it will remain classified as a restructured loan. The following table presents nonaccrual and performing restructured loans by loan portfolio.

All loans modified in a troubled debt restructuring are evaluated for impairment. The nature and extent of the impairment of restructured loans, including those which have experienced a subsequent payment default, is considered in the determination of an appropriate level of the allowance for loan losses.

NOTE 8: Goodwill and Other Intangible Assets

Goodwill

Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The impairment testing process is conducted by assigning net assets and goodwill to each reporting unit. An initial qualitative evaluation is made to assess the likelihood of impairment and determine whether further quantitative testing to calculate the fair value is necessary. When the qualitative evaluation indicates that impairment is more likely than not, quantitative testing is required whereby the fair value of each reporting unit is calculated and compared to the recorded book value, “step one.” If the calculated fair value of the reporting unit exceeds its carrying value, goodwill is not considered impaired and “step two” is not considered necessary. If the carrying value of a reporting unit exceeds its calculated fair value, the impairment test continues (“step two”) by comparing the carrying value of the reporting unit’s goodwill to the implied fair value of goodwill. The implied fair value is computed by adjusting all assets and liabilities of the reporting unit to current fair value with the offset adjustment to goodwill. The adjusted goodwill balance is the implied fair value of the goodwill. An impairment charge is recognized if the carrying value of goodwill exceeds the implied fair value of goodwill.

The Corporation conducted its most recent annual impairment test in May 2015, utilizing a qualitative assessment. Factors that management considered in this assessment included macroeconomic conditions, industry and market considerations, overall financial performance of the Corporation and each reporting unit (both current and projected), changes in management strategy, and changes in the composition or carrying amount of net assets. In addition, management considered the increases in both the Corporation’s common stock price and in the overall bank common stock index (based on the NASDAQ Bank Index and the S&P 400 Regional Bank Sub-Industry Index), as well as the Corporation’s earnings per common share trend over the past year. Based

Table of Contents

on these assessments, management concluded that the 2015 annual qualitative impairment assessment indicated that it is more likely than not that the estimated fair value exceeded the carrying value (including goodwill) for each reporting unit. Therefore, a step one quantitative analysis was not required. There were no events since the date of the last impairment testing that have changed the Corporation's impairment assessment conclusion.

At September 30, 2015 , the Corporation had goodwill of $969 million , compared to $929 million at December 31, 2014. There was an addition to the carrying amount of goodwill of approximately $40 million for the Ahmann & Martin Co. acquisition that occurred during the quarter ended March 31, 2015. See Note 2 for additional information on the Ahmann & Martin Co. acquisition.

Other Intangible Assets

The Corporation has other intangible assets that are amortized, consisting of core deposit intangibles, other intangibles (primarily related to customer relationships acquired in connection with the Corporation’s insurance agency acquisitions), and mortgage servicing rights. There was an addition to the gross carrying amount of other intangibles of approximately $12 million for the customer relationships acquired with the Ahmann & Martin Co. acquisition that occurred during the quarter ended March 31, 2015. See Note 2 for additional information on the Ahmann & Martin Co. acquisition. For core deposit intangibles and other intangibles, changes in the gross carrying amount, accumulated amortization, and net book value were as follows.

The Corporation sells residential mortgage loans in the secondary market and typically retains the right to service the loans sold. Mortgage servicing rights are amortized in proportion to and over the period of estimated net servicing income, and assessed for impairment at each reporting date.

The Corporation periodically evaluates its mortgage servicing rights asset for impairment. Impairment is assessed based on fair value at each reporting date using estimated prepayment speeds of the underlying mortgage loans serviced and stratifications based on the risk characteristics of the underlying loans (predominantly loan type and note interest rate). As mortgage interest rates fall, prepayment speeds are usually faster and the value of the mortgage servicing rights asset generally decreases, requiring additional valuation reserve. Conversely, as mortgage interest rates rise, prepayment speeds are usually slower and the value of the mortgage servicing rights asset generally increases, requiring less valuation reserve. A valuation allowance is established, through a charge to earnings, to the extent the amortized cost of the mortgage servicing rights exceeds the estimated fair value by stratification. If it is later determined that all or a portion of the temporary impairment no longer exists for a stratification, the valuation is reduced through a recovery to earnings. An other-than-temporary impairment (i.e., recoverability is considered remote when considering interest rates and loan pay off activity) is recognized as a write-down of the mortgage servicing rights asset and the related valuation allowance (to the extent a valuation allowance is available) and then against earnings. A direct write-down permanently reduces the carrying value of the mortgage servicing rights asset and valuation allowance, precluding subsequent recoveries. See Note 13 for a discussion of the recourse provisions on sold residential mortgage loans. See Note 14 which further discusses fair value measurement relative to the mortgage servicing rights asset.

Securities sold under agreements to repurchase ("repurchase agreements")

The Corporation enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities. Under these arrangements, the Corporation may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Corporation to repurchase the assets. The obligation to repurchase the securities is reflected as a liability on the Corporation’s consolidated balance sheets, while the securities underlying the repurchase agreements remain in the respective investment securities asset accounts (i.e., there is no offsetting or netting of the investment securities assets with the repurchase agreement liabilities). See Note 12 for additional disclosures on balance sheet offsetting.

The Corporation utilizes securities sold under agreements to repurchase to facilitate the needs of its customers. As of September 30, 2015, the Corporation pledged GSE mortgage-related securities with a fair value of $648 million as collateral for the repurchase agreements. Securities pledged as collateral under repurchase agreements are maintained with the Corporation's safekeeping agents and are monitored on a daily basis due to the market risk of fair value changes in the underlying securities. The Corporation generally pledges excess securities to ensure there is sufficient collateral to satisfy short-term fluctuations in both the repurchase agreement balances and the fair value of the underlying securities.

The remaining contractual maturity of the securities sold under agreements to repurchase in the consolidated balance sheets as of September 30, 2015 is presented in the following table.

Long-term funding:

FHLB Advances: Long-term FHLB advances had a weighted-average interest rate of 0.13% at September 30, 2015 and 0.11% at December 31, 2014 . The FHLB advances are indexed to the FHLB discount note and reprice at varying intervals. The advances offer flexible, low cost, long-term funding that improves the Corporation’s liquidity profile.

2011 Senior Notes: In March 2011, the Corporation issued $300 million of senior notes due March 2016, and callable February 2016, with a 5.125% fixed coupon at a discount. In September 2011, the Corporation “re-opened” the offering and issued an additional $130 million of the same notes at a premium.

2014 Senior Notes: In November 2014, the Corporation issued $ 250 million of senior notes, due November 2019, and callable October 2019. The senior notes have a fixed coupon interest rate of 2.75% and were issued at a discount.

2014 Subordinated Notes: In November 2014, the Corporation issued $250 million of 10 -year subordinated notes, due January 2025, and callable October 2024. The subordinated notes have a fixed coupon interest rate of 4.25% and were issued at a discount.

NOTE 10: Income Taxes

The Corporation recognized income tax expense of $66 million for the nine months ended September 30, 2015 , compared to income tax expense of $67 million for the comparable period in 2014 . The effective tax rate was 31.14% for the first nine months of 2015 , compared to an effective tax rate of 32.02% for the first nine months of 2014 .

NOTE 11: Derivative and Hedging Activities

The Corporation facilitates customer borrowing activity by providing various interest rate risk management solutions through its capital markets area. To date, all of the notional amounts of customer transactions have been matched with a mirror swap with another counterparty. The Corporation has used, and may again use in the future, derivative instruments to hedge the variability in interest payments or protect the value of certain assets and liabilities recorded on its consolidated balance sheets from changes in interest rates. The predominant derivative and hedging activities include interest rate-related instruments (swaps and caps), foreign currency exchange forwards, written options, purchased options, and certain mortgage banking activities. The contract or notional amount of a derivative is used to determine, along with the other terms of the derivative, the amounts to be exchanged between the counterparties. The Corporation is exposed to credit risk in the event of nonperformance by counterparties to financial instruments. To mitigate the counterparty risk, interest rate-related instruments generally contain language outlining collateral pledging requirements for each counterparty. Collateral must be posted when the market value exceeds certain mutually agreed upon threshold limits. The Corporation was required to pledge $10 million of investment securities as collateral at September 30, 2015 , and pledged $11 million of investment securities as collateral at December 31, 2014 . Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, as of June 10, 2013, the Corporation must clear all LIBOR interest rate swaps through a clearing house if it can be cleared. As such, the Corporation is required to pledge cash collateral for the margin. At September 30, 2015 , the Corporation posted cash collateral for the margin of $33 million , compared to $15 million at December 31, 2014 .

The Corporation’s derivative and hedging instruments are recorded at fair value on the consolidated balance sheets. The fair value of the Corporation’s interest rate-related instruments is determined using discounted cash flow analysis on the expected cash flows of each derivative and also includes a nonperformance / credit risk component (credit valuation adjustment). See Note 14 for additional fair value information and disclosures.

Free standing derivatives

The Corporation enters into various derivative contracts which are designated as free standing derivative contracts. These derivative contracts are not designated against specific assets and liabilities on the balance sheet or forecasted transactions and, therefore, do not qualify for hedge accounting treatment. Such derivative contracts are carried at fair value on the consolidated balance sheets with changes in the fair value recorded as a component of Capital market fees, net, and typically include interest rate-related instruments (swaps and caps).

Table of Contents

Free standing derivative products are entered into primarily for the benefit of commercial customers seeking to manage their exposures to interest rate risk. The Corporation’s market risk from unfavorable movements in interest rates related to these derivative contracts is generally economically hedged by concurrently entering into offsetting derivative contracts. The offsetting derivative contracts have identical notional values, terms and indices. See Note 12 for additional information and disclosures on balance sheet offsetting.

Mortgage derivatives

Interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans are considered derivative instruments, and the fair value of these commitments is recorded on the consolidated balance sheets with the changes in fair value recorded as a component of mortgage banking, net.

Foreign currency exchange derivatives

The Corporation provides foreign currency exchange services to customers, primarily forward contracts. Our customers enter into a foreign currency exchange forward with the Corporation as a means for them to mitigate exchange rate risk. The Corporation mitigates its risk by then entering into an offsetting foreign currency exchange derivative contract. Such foreign currency exchange contracts are carried at fair value on the consolidated balance sheets with changes in fair value recorded as a component of Capital market fees, net.

Written and purchased option derivatives (time deposit)

Historically, the Corporation had entered into written and purchased option derivative instruments to facilitate an equity linked time deposit product (the “Power CD”), which the Corporation ceased offering in September 2013. The Power CD was a time deposit that provided the purchaser a guaranteed return of principal at maturity plus a potential equity return (a written option), while the Corporation received a known stream of funds based on the equity return (a purchased option). The written and purchased options are mirror derivative instruments which are carried at fair value on the consolidated balance sheets.

NOTE 12: Balance Sheet Offsetting

Interest Rate-Related Instruments (“Interest Agreements”)

The Corporation enters into interest rate-related instruments to facilitate the interest rate risk management strategies of commercial customers. The Corporation mitigates this risk by entering into equal and offsetting interest rate-related instruments with highly rated third party financial institutions. The interest agreements are free-standing derivatives and are recorded at fair value in the Corporation’s consolidated balance sheets. The Corporation is party to master netting arrangements with its financial institution counterparties; however, the Corporation does not offset assets and liabilities under these arrangements for financial statement presentation purposes. The master netting arrangements provide for a single net settlement of all interest agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral, usually in the form of investment securities and cash, is posted by the counterparty with net liability positions in accordance with contract thresholds. See Note 11 for additional information on the Corporation’s derivative and hedging activities.

Securities Sold Under Agreements to Repurchase (“Repurchase Agreements”)

The Corporation enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities. These repurchase agreements are accounted for as collateralized financing arrangements (i.e., secured borrowings) and not as a sale and subsequent repurchase of securities (i.e., there is no offsetting or netting of the investment securities assets with the repurchase agreement liabilities). The right of set-off for a repurchase agreement resembles a secured borrowing, whereby the collateral would be used to settle the fair value of the repurchase agreement should the Corporation be in default (e.g., fails to make an interest payment to the counterparty). In addition, the Corporation does not enter into reverse repurchase agreements; therefore, there is no such offsetting to be done with the repurchase agreements. See Note 9 for additional disclosures on repurchase agreements.

Table of Contents

The following table presents the assets and liabilities subject to an enforceable master netting arrangement as of September 30, 2015 and December 31, 2014 . The interest agreements we have with our commercial customers are not subject to an enforceable master netting arrangement, and therefore, are excluded from this table.

Lending-related Commitments

As a financial services provider, the Corporation routinely enters into commitments to extend credit. Such commitments are subject to the same credit policies and approval process accorded to loans made by the Corporation, with each customer’s creditworthiness evaluated on a case-by-case basis. The commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. The Corporation’s exposure to credit loss in the event of nonperformance by the other party to these financial instruments is represented by the contractual amount of those instruments. The amount of collateral obtained, if deemed necessary by the Corporation upon extension of credit, is based on management’s credit evaluation of the customer. Since a significant portion of commitments to extend credit are subject to specific restrictive loan covenants or may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements. An allowance for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to unfunded commitments (including unfunded loan commitments and letters of credit). The allowance for unfunded commitments totaled $24 million at September 30, 2015 down from $25 million at December 31, 2014 , and is included in accrued expenses and other liabilities on the consolidated balance sheets. See Note 7 for additional information on the allowance for unfunded commitments.

Lending-related commitments include commitments to extend credit, commitments to originate residential mortgage loans held for sale, commercial letters of credit, and standby letters of credit. Commitments to extend credit are legally binding agreements

to lend to customers at predetermined interest rates, as long as there is no violation of any condition established in the contracts. Interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans are considered derivative instruments, and the fair value of these commitments is recorded on the consolidated balance sheets. The Corporation’s derivative and hedging activity is further described in Note 11. Commercial and standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Commercial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and the third party, while standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party.

Other Commitments

The Corporation has principal investment commitments to provide capital-based financing to private and public companies through either direct investments in specific companies or through investment funds and partnerships. The timing of future cash requirements to fund such commitments is generally dependent on the investment cycle, whereby privately held companies are funded by private equity investors and ultimately sold, merged, or taken public through an initial offering, which can vary based on overall market conditions, as well as the nature and type of industry in which the companies operate. The Corporation also invests in low-income housing, small-business commercial real estate, new market tax credit projects, and historic tax credit projects to promote the revitalization of low-to-moderate-income neighborhoods throughout the local communities of its bank subsidiary. As a limited partner in these unconsolidated projects, the Corporation is allocated tax credits and deductions associated with the underlying projects. The aggregate carrying value of these investments at September 30, 2015 was $41 million , compared to $27 million at December 31, 2014 , included in other assets on the consolidated balance sheets. Related to these investments, the Corporation had remaining commitments to fund of $33 million at September 30, 2015 and $28 million at December 31, 2014 .

Contingent Liabilities

The Corporation is party to various pending and threatened claims and legal proceedings arising in the normal course of business activities, some of which involve claims for substantial amounts. Although there can be no assurance as to the ultimate outcomes, the Corporation believes it has meritorious defenses to the claims asserted against it in its current outstanding matters, including the matters described below, and with respect to such legal proceedings, intends to continue to defend itself vigorously. The Corporation will consider settlement of cases when, in management’s judgment, it is in the best interests of both the Corporation and its shareholders.

On at least a quarterly basis, the Corporation assesses its liabilities and contingencies in connection with all pending or threatened claims and litigation, utilizing the most recent information available. On a matter by matter basis, an accrual for loss is established for those matters which the Corporation believes it is probable that a loss may be incurred and that the amount of such loss can be reasonably estimated. Once established, each accrual is adjusted as appropriate to reflect any subsequent developments. Accordingly, management’s estimate will change from time to time, and actual losses may be more or less than the current estimate. For matters where a loss is not probable, or the amount of the loss cannot be estimated, no accrual is established.

Resolution of legal claims is inherently unpredictable, and in many legal proceedings various factors exacerbate this inherent unpredictability, including where the damages sought are unsubstantiated or indeterminate, it is unclear whether a case brought as a class action will be allowed to proceed on that basis, discovery is not complete, the proceeding is not yet in its final stages, the matters present legal uncertainties, there are significant facts in dispute, there are a large number of parties (including where it is uncertain how liability, if any, will be shared among multiple defendants), or there is a wide range of potential results.

A lawsuit, R.J. ZAYED v. Associated Bank, N.A. , was filed in the United States District Court for the District of Minnesota on January 29, 2013. The lawsuit relates to a Ponzi scheme perpetrated by Oxford Global Partners and related entities (“Oxford”) and individuals and was brought by the receiver for Oxford. Oxford was a depository customer of Associated Bank, N.A. (the "Bank"). The lawsuit claims that the Bank is liable for failing to uncover the Oxford Ponzi scheme, and specifically alleges the Bank aided and abetted (1) the fraudulent scheme; (2) a breach of fiduciary duty; (3) conversion; and (4) false representations and omissions. The lawsuit seeks unspecified consequential and punitive damages. The District Court granted the Bank’s motion to dismiss the complaint on September 30, 2013. On March 2, 2015, the U.S. Court of Appeals for the Eighth Circuit reversed the District Court and remanded the case back to the District Court for further proceedings. It is not possible for management to assess the probability of a material adverse outcome or reasonably estimate the amount of any potential loss at this time. A lawsuit by investors in the same Ponzi scheme, Herman Grad, et al v. Associated Bank, N.A. , brought in Brown County, Wisconsin in October 2009 was dismissed by the circuit court, and the dismissal was affirmed by the Wisconsin Court of Appeals in June 2011 in an unpublished opinion.

On May 22, 2015, the Bank entered into a Conciliation Agreement ("Conciliation Agreement") with the U.S. Department of Housing and Urban Development ("HUD") which resolved the previously disclosed HUD investigation into the Bank's lending practices during the years 2008-2010. The Bank's commitments under the Conciliation Agreement are spread over a three -year

period and include commitments to do the following in minority communities: make mortgage loans of approximately $196 million ; open one branch and four loan production offices; establish special financing programs; make affordable home repair grants; engage in affirmative marketing outreach; provide financial education programs; and make grants to support community reinvestment training and education. The cost of these commitments will be spread over four calendar years and is not expected to have a material impact on the Corporation's financial condition or results of operation.

Beginning in late 2013, the Corporation began reviewing a variety of legacy products provided by third parties, including debt protection and identity protection products. In connection with this review, the Corporation has made, and plans to make, remediation payments to affected customers and former customers, and has reserved accordingly.

A variety of consumer products, including the legacy debt protection and identity protection products referred to above, and mortgage and deposit products, and certain fees and charges related to such products, have come under increased regulatory scrutiny. It is possible that regulatory authorities could bring enforcement actions, including civil money penalties, or take other actions against the Corporation and the Bank in regard to these consumer products. The Bank could also determine of its own accord, or be required by regulators, to refund or otherwise make remediation payments to customers in connection with these products. It is not possible at this time for management to assess the probability of a material adverse outcome or reasonably estimate the amount of any potential loss related to such matters.

Mortgage Repurchase Reserve

The Corporation sells residential mortgage loans to investors in the normal course of business. Residential mortgage loans sold to others are predominantly conventional residential first lien mortgages originated under our usual underwriting procedures, and are most often sold on a nonrecourse basis, primarily to the GSEs. The Corporation’s agreements to sell residential mortgage loans in the normal course of business usually require certain representations and warranties on the underlying loans sold, related to credit information, loan documentation, collateral, and insurability. Subsequent to being sold, if a material underwriting deficiency or documentation defect is discovered, the Corporation may be obligated to repurchase the loan or reimburse the GSEs for losses incurred (collectively, “make whole requests”). The make whole requests and any related risk of loss under the representations and warranties are largely driven by borrower performance.

As a result of make whole requests, the Corporation has repurchased loans with principal balances of approximately $3 million and $5 million during the nine months ended September 30, 2015 and the year ended December 31, 2014 , respectively, and paid loss reimbursement or settlement claims of approximately $117,000 and $734,000 during the nine months ended September 30, 2015 and the year ended December 31, 2014 , respectively. Make whole requests during 2014 and the first nine months of 2015 generally arose from loans sold during the period January 1, 2006 to September 30, 2015 , which totaled $19.6 billion at the time of sale, and consisted primarily of loans sold to GSEs. As of September 30, 2015 , approximately $7.5 billion of these sold loans remain outstanding.

The balance in the mortgage repurchase reserve at the balance sheet date reflects the estimated amount of potential loss the Corporation could incur from repurchasing a loan, as well as loss reimbursements, indemnifications, and other settlement resolutions. The following summarizes the changes in the mortgage repurchase reserve.

The Corporation may also sell residential mortgage loans with limited recourse (limited in that the recourse period ends prior to the loan’s maturity, usually after certain time and / or loan paydown criteria have been met), whereby repurchase could be required if the loan had defined delinquency issues during the limited recourse periods. At September 30, 2015 and December 31, 2014 , there were approximately $69 million and $46 million , respectively, of residential mortgage loans sold with such recourse risk. There have been limited instances and immaterial historical losses on repurchases for recourse under the limited recourse criteria.

The Corporation has a subordinate position to the FHLB in the credit risk on residential mortgage loans it sold to the FHLB in exchange for a monthly credit enhancement fee. The Corporation has not sold loans to the FHLB with such credit risk retention

since February 2005. At September 30, 2015 and December 31, 2014 , there were $142 million and $178 million , respectively, of such residential mortgage loans with credit risk recourse, upon which there have been negligible historical losses to the Corporation.

NOTE 14: Fair Value Measurements

Fair value represents the estimated price at which an orderly transaction to sell an asset or to transfer a liability would take place between market participants at the measurement date under current market conditions (i.e., an exit price concept). Following is a description of the valuation methodologies used for the Corporation’s more significant instruments measured on a recurring basis at fair value, including the general classification of such instruments pursuant to the valuation hierarchy.

Investment securities available for sale

Where quoted prices are available in an active market, investment securities are classified in Level 1 of the fair value hierarchy. Level 1 investment securities primarily include U.S. Treasury and exchange-traded debt and equity securities. If quoted market prices are not available for the specific security, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows, with consideration given to the nature of the quote and the relationship of recently evidenced market activity to the fair value estimate, and are classified in Level 2 of the fair value hierarchy. Examples of these investment securities include obligations of state and political subdivisions ("municipal securities"), mortgage-related securities and other debt securities. Lastly, in certain cases where there is limited activity or less transparency around inputs to the estimated fair value, securities are classified within Level 3 of the fair value hierarchy. To validate the fair value estimates, assumptions, and controls, the Corporation looks to transactions for similar instruments and utilizes independent pricing provided by third party vendors or brokers and relevant market indices. While none of these sources are solely indicative of fair value, they serve as directional indicators for the appropriateness of the Corporation’s fair value estimates. The Corporation has determined that the fair value measures of its investment securities are classified predominantly within Level 1 or 2 of the fair value hierarchy. See Note 6 for additional disclosure regarding the Corporation’s investment securities.

Derivative financial instruments (interest rate-related instruments )

The Corporation has used, and may again use in the future, interest rate swaps to manage its interest rate risk. In addition, the Corporation offers customer interest rate-related instruments (swaps and caps) to service our customers’ needs, for which the Corporation simultaneously enters into offsetting derivative financial instruments (i.e., mirror interest rate-related instruments) with third parties to manage its interest rate risk associated with these financial instruments. The valuation of the Corporation’s derivative financial instruments is determined using discounted cash flow analysis on the expected cash flows of each derivative and, also includes a nonperformance / credit risk component (credit valuation adjustment). See Note 11 for additional disclosure regarding the Corporation’s derivative financial instruments.

The discounted cash flow analysis component in the fair value measurement reflects the contractual terms of the derivative financial instruments, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. More specifically, the fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments), with the variable cash payments (or receipts) based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. Likewise, the fair values of interest rate options (i.e., interest rate caps) are determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates fall below (or rise above) the strike rate of the floors (or caps), with the variable interest rates used in the calculation of projected receipts on the floor (or cap) based on an expectation of future interest rates derived from observable market interest rate curves and volatilities.

The Corporation also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative financial instruments for the effect of nonperformance risk, the Corporation has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. In conjunction with the FASB’s fair value measurement guidance, the Corporation made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.

While the Corporation has determined that the majority of the inputs used to value its derivative financial instruments fall within Level 2 of the fair value hierarchy, the credit valuation adjustments utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. The Corporation has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions as of September 30, 2015 , and December 31, 2014 , and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivative financial instruments. Therefore, the Corporation has determined that the fair value measures of its derivative financial instruments in their entirety are classified within Level 2 of the fair value hierarchy.

Derivative financial instruments (foreign currency exchange forwards )

The Corporation provides foreign currency exchange services to customers. In addition, the Corporation may enter into a foreign currency exchange forward to mitigate the exchange rate risk attached to the cash flows of a loan or as an offsetting contract to a forward entered into as a service to our customer. The valuation of the Corporation’s foreign currency exchange forwards is determined using quoted prices of foreign currency exchange forwards with similar characteristics, with consideration given to the nature of the quote and the relationship of recently evidenced market activity to the fair value estimate, and are classified in Level 2 of the fair value hierarchy. See Note 11 for additional disclosures regarding the Corporation’s foreign currency exchange forwards.

Derivative financial instruments (mortgage derivatives)

Mortgage derivatives include interest rate lock commitments to originate residential mortgage loans held for sale to individual customers and forward commitments to sell residential mortgage loans to various investors. The Corporation relies on an internal valuation model to estimate the fair value of its interest rate lock commitments to originate residential mortgage loans held for sale, which includes grouping the interest rate lock commitments by interest rate and terms, applying an estimated pull-through rate based on historical experience, and then multiplying by quoted investor prices determined to be reasonably applicable to the loan commitment groups based on interest rate, terms, and rate lock expiration dates of the loan commitment groups.

The Corporation also relies on an internal valuation model to estimate the fair value of its forward commitments to sell residential mortgage loans (i.e., an estimate of what the Corporation would receive or pay to terminate the forward delivery contract based on market prices for similar financial instruments), which includes matching specific terms and maturities of the forward commitments against applicable investor pricing available. While there are Level 2 and 3 inputs used in the valuation models, the Corporation has determined that the majority of the inputs significant in the valuation of both of the mortgage derivatives fall within Level 3 of the fair value hierarchy. See Note 11 for additional disclosure regarding the Corporation’s mortgage derivatives.

Following is a description of the valuation methodologies used for the Corporation’s more significant instruments measured on a nonrecurring basis at the lower of amortized cost or estimated fair value, including the general classification of such instruments pursuant to the valuation hierarchy.

Loans Held for Sale

Loans held for sale, which consist generally of current production of certain fixed-rate, first-lien residential mortgage loans, are carried at the lower of cost or estimated fair value. The estimated fair value was based on what secondary markets are currently offering for portfolios with similar characteristics, which the Corporation classifies as a Level 2 nonrecurring fair value measurement.

Impaired Loans

The Corporation considers a loan impaired when it is probable that the Corporation will be unable to collect all amounts due according to the original contractual terms of the note agreement, including both principal and interest. Management has determined that commercial and consumer loan relationships that have nonaccrual status or have had their terms restructured in a troubled debt restructuring meet this impaired loan definition. For individually evaluated impaired loans, the amount of impairment is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, the estimated fair value of the underlying collateral for collateral-dependent loans, or the estimated liquidity of the note. See Note 7 for additional information regarding the Corporation’s impaired loans.

Mortgage servicing rights

Mortgage servicing rights do not trade in an active, open market with readily observable prices. While sales of mortgage servicing rights do occur, the precise terms and conditions typically are not readily available to allow for a “quoted price for similar assets” comparison. Accordingly, the Corporation utilizes an independent valuation from a third party which uses a discounted cash flow model to estimate the fair value of its mortgage servicing rights. The valuation model incorporates prepayment assumptions to project mortgage servicing rights cash flows based on the current interest rate scenario, which is then discounted to estimate an expected fair value of the mortgage servicing rights. The valuation model considers portfolio characteristics of the underlying mortgages, contractually specified servicing fees, prepayment assumptions, discount rate assumptions, delinquency rates, late charges, other ancillary revenue, costs to service, and other economic factors. The Corporation periodically reviews and assesses the underlying inputs and assumptions used in the model. In addition, the Corporation compares its fair value estimates and assumptions to observable market data for mortgage servicing rights, where available, and to recent market activity and actual portfolio experience. Due to the nature of the valuation inputs, mortgage servicing rights are classified within Level 3 of the fair value hierarchy. The Corporation uses the amortization method (i.e., lower of amortized cost or estimated fair value measured on

Table of Contents

a nonrecurring basis), not fair value measurement accounting, for its mortgage servicing rights assets. See Note 8 for additional disclosure regarding the Corporation’s mortgage servicing rights.

For Level 3 assets and liabilities measured at fair value on a recurring or nonrecurring basis as of September 30, 2015 , the Corporation utilized the following valuation techniques and significant unobservable inputs.

Derivative financial instruments (mortgage derivative – interest rate lock commitments to originate residential mortgage loans held for sale)

The significant unobservable input used in the fair value measurement of the Corporation’s mortgage derivative interest rate lock commitments (“IRLC”) is the closing ratio, which represents the percentage of loans currently in a lock position which management estimates will ultimately close. The closing ratio calculation takes into consideration historical data and loan-level data, particularly the change in the current interest rates from the time of initial rate lock. The closing ratio is periodically reviewed for reasonableness and reported to the Mortgage Risk Management Committee. At September 30, 2015 , the closing ratio was 87% .

Impaired loans

For individually evaluated impaired loans, the amount of impairment is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, the estimated fair value of the underlying collateral for collateral-dependent loans, or the estimated liquidity of the note, resulting in average discounts of 10% to 20% .

Mortgage servicing rights

The discounted cash flow analyses that generate expected market prices utilize the observable characteristics of the mortgage servicing rights portfolio, as well as certain unobservable valuation parameters. The significant unobservable inputs used in the fair value measurement of the Corporation’s mortgage servicing rights are the weighted average constant prepayment rate and weighted average discount rate, which were 13.4% and 9.6% at September 30, 2015 , respectively. Significant increases (decreases) in any of those inputs in isolation could result in a significantly lower (higher) fair value measurement.

These parameter assumptions fall within a range that the Corporation, in consultation with an independent third party, believes purchasers of servicing would apply to such portfolios sold into the current secondary servicing market. Discussions are held with members from management to reconcile the fair value estimates and the key assumptions used by the respective parties in arriving at those estimates. The Mortgage Risk Management Committee is responsible for providing control over the valuation methodology and key assumptions. To assess the reasonableness of the fair value measurement, the Corporation also compares the fair value and constant prepayment rate to a value calculated by an independent third party on an annual basis.

Certain nonfinancial assets measured at fair value on a nonrecurring basis include other real estate owned (upon initial recognition or subsequent impairment), nonfinancial assets and nonfinancial liabilities measured at fair value in the second step of a goodwill impairment test, and intangible assets and other nonfinancial long-lived assets measured at fair value for impairment assessment.

During the first nine months of 2015 and the full year 2014 , certain other real estate owned, upon initial recognition, was re-measured and reported at fair value through a charge off to the allowance for loan losses based upon the estimated fair value of the other real estate owned, less estimated selling costs. The fair value of other real estate owned, upon initial recognition or subsequent impairment, was estimated using appraised values, which the Corporation classifies as a Level 2 nonrecurring fair value measurement. Other real estate owned measured at fair value upon initial recognition totaled approximately $6 million for the first nine months of 2015 and $21 million for the year ended December 31, 2014 . In addition to other real estate owned measured at fair value upon initial recognition, the Corporation also recorded write-downs to the balance of other real estate owned for subsequent impairment of less than $1 million and $2 million to asset losses, net for the nine months ended September 30, 2015 and the year ended December 31, 2014 , respectively.

(1)	The commitment on standby letters of credit was $317 million and $353 million at September 30, 2015 and December 31, 2014 , respectively. See Note 13 for additional information on the standby letters of credit and for information on the fair value of lending-related commitments.

Cash and due from banks, interest-bearing deposits in other financial institutions, federal funds sold and securities purchased under agreements to resell, and accrued interest receivable – For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Investment securities (held to maturity and available for sale) – The fair value of investment securities is based on quoted prices in active markets, or if quoted prices are not available for a specific security, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows.

FHLB and Federal Reserve Bank stocks – The carrying amount is a reasonable fair value estimate for the Federal Reserve Bank and Federal Home Loan Bank stocks given their “restricted” nature (i.e., the stock can only be sold back to the respective institutions (Federal Home Loan Bank or Federal Reserve Bank) or another member institution at par).

Loans held for sale – The fair value estimation process for the loans held for sale portfolio is segregated by loan type and is based on what secondary markets are currently offering for portfolios with similar characteristics.

Loans, net – The fair value estimation process for the loan portfolio uses an exit price concept and reflects discounts the Corporation believes are consistent with liquidity discounts in the market place. Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial and industrial, real estate construction, commercial real estate (owner occupied and investor), lease financing, residential mortgage, home equity, other installment, and credit cards. The fair value of loans is estimated by discounting the future cash flows using the current rates at which similar loans would be

Table of Contents

made to borrowers with similar credit ratings and for similar maturities. The fair value analysis also included other assumptions to estimate fair value, intended to approximate those a market participant would use in an orderly transaction, with adjustments for discount rates, interest rates, liquidity, and credit spreads, as appropriate.

Bank owned life insurance – The fair value of bank owned life insurance approximates the carrying amount, because upon liquidation of these investments, the Corporation would receive the cash surrender value which equals the carrying amount.

Deposits – The fair value of deposits with no stated maturity such as noninterest-bearing demand deposits, savings, interest-bearing demand deposits, and money market deposits, is equal to the amount payable on demand as of the balance sheet date. The fair value of Brokered CDs and other time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. However, if the estimated fair value of Brokered CDs and other time deposits is less than the carrying value, the carrying value is reported as the fair value.

Accrued interest payable and short-term funding – For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Long-term funding – Rates currently available to the Corporation for debt with similar terms and remaining maturities are used to estimate the fair value of existing long-term funding.

Interest rate-related instruments – The fair value of interest rate-related instruments is determined using discounted cash flow analysis on the expected cash flows of each derivative. The Corporation also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements.

Foreign currency exchange forwards – The fair value of the Corporation’s foreign currency exchange forwards is determined using quoted prices of foreign currency exchange forwards with similar characteristics, with consideration given to the nature of the quote and the relationship of recently evidenced market activity to the fair value estimate.

Standby letters of credit – The fair value of standby letters of credit represent deferred fees arising from the related off-balance sheet financial instruments. These deferred fees approximate the fair value of these instruments and are based on several factors, including the remaining terms of the agreement and the credit standing of the customer.

Interest rate lock commitments to originate residential mortgage loans held for sale – The Corporation relies on an internal valuation model to estimate the fair value of its interest rate lock commitments to originate residential mortgage loans held for sale, which includes grouping the interest rate lock commitments by interest rate and terms, applying an estimated pull-through rate based on historical experience, and then multiplying by quoted investor prices determined to be reasonably applicable to the loan commitment groups based on interest rate, terms, and rate lock expiration dates of the loan commitment groups.

Forward commitments to sell residential mortgage loans – The Corporation relies on an internal valuation model to estimate the fair value of its forward commitments to sell residential mortgage loans (i.e., an estimate of what the Corporation would receive or pay to terminate the forward delivery contract based on market prices for similar financial instruments), which includes matching specific terms and maturities of the forward commitments against applicable investor pricing available.

Purchased and written options – The fair value of the Corporation’s purchased and written options is determined using quoted prices of the underlying stocks.

Limitations – Fair value estimates are made at a specific point in time, based on relevant market information and other information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Corporation’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Corporation’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

NOTE 15: Retirement Plans

The Corporation has a noncontributory defined benefit retirement plan (the Retirement Account Plan (“RAP”)) covering substantially all full-time employees. The benefits are based primarily on years of service and the employee’s compensation paid. Employees of acquired entities generally participate in the RAP after consummation of the business combinations. Any retirement plans of acquired entities are typically merged into the RAP after completion of the mergers, and credit is usually given to employees for years of service at the acquired institution for vesting and eligibility purposes. In connection with the First Federal acquisition in October 2004, the Corporation assumed the First Federal pension plan (the “First Federal Plan”). The First Federal Plan was

Table of Contents

frozen on December 31, 2004 and qualified participants in the First Federal Plan became eligible to participate in the RAP as of January 1, 2005. Additional discussion and information on the RAP and the First Federal Plan are collectively referred to below as the “Pension Plan”.

The Corporation also provides healthcare access for eligible retired employees in its Postretirement Plan (the “Postretirement Plan”). Retirees who are at least 55 years of age with 5 years of service are eligible to participate in the Postretirement Plan. The Corporation has no plan assets attributable to the Postretirement Plan. The Corporation reserves the right to terminate or make changes to the Postretirement Plan at any time.

The components of net periodic benefit cost for the Pension and Postretirement Plans for the three and nine months ended September 30, 2015 and 2014 , respectively, and for the full year 2014 were as follows.

The Corporation’s funding policy is to pay at least the minimum amount required by the funding requirements of federal law and regulations, with consideration given to the maximum funding amounts allowed. The Corporation regularly reviews the funding of its Pension Plan.

NOTE 16: Segment Reporting

The Corporation utilizes a risk-based internal profitability measurement system to provide strategic business unit reporting. The profitability measurement system is based on internal management methodologies designed to produce consistent results and reflect the underlying economics of the units. Certain strategic business units have been combined for segment information reporting purposes where the nature of the products and services, the type of customer and the distribution of those products and services are similar. The three reportable segments are Corporate and Commercial Specialty; Community, Consumer, and Business; and Risk Management and Shared Services, with no segment representing more than half of the assets of the Corporation as a whole.

The financial information of the Corporation’s segments has been compiled utilizing the accounting policies described in the Corporation's 2014 annual report on Form 10-K with certain exceptions, as noted below. The Corporation allocates interest income or interest expense using a funds transfer pricing methodology that charges users of funds (assets) interest expense and credits providers of funds (liabilities, primarily deposits) with income based on the maturity, prepayment and / or repricing characteristics of the assets and liabilities. The net effect of this allocation is recorded in the Risk Management and Shared Services segment. A credit provision is allocated to segments based on the expected long-term annual net charge off rates attributable to the credit risk of loans managed by the segment during the period. In contrast, the level of the consolidated provision for credit losses is determined using the methodologies described in the Corporation's 2014 annual report on Form 10-K to assess the overall appropriateness of the allowance for credit losses. The net effect of the credit provision is recorded in Risk Management and Shared Services. Indirect expenses incurred by certain centralized support areas are allocated to segments based on actual usage (for example, volume measurements) and other criteria. Certain types of administrative expense and bank-wide expense accruals (including amortization of core deposit and other intangible assets associated with acquisitions) are generally not allocated to segments. Income taxes are allocated to segments based on the Corporation’s estimated effective tax rate, with certain segments adjusted for any tax-exempt income or non-deductible expenses. Equity is allocated to the segments based on regulatory capital requirements and in proportion to an assessment of the inherent risks associated with the business of the segment (including interest, credit and operating risk).

Table of Contents

The management accounting policies and processes utilized in compiling segment financial information are highly subjective and, unlike financial accounting, are not based on authoritative guidance similar to U.S. generally accepted accounting principles. As a result, reported segments and the financial information of the reported segments are not necessarily comparable with similar information reported by other financial institutions. Furthermore, changes in management structure or allocation methodologies and procedures may result in changes in previously reported segment financial data. During 2015, certain organizational and methodology changes were made and, accordingly, 2014 results have been restated and presented on a comparable basis.

A description of each business segment is presented below.

Corporate and Commercial Specialty — The Corporate and Commercial Specialty segment serves a wide range of customers including larger businesses, developers, non-profits, municipalities, and financial institutions.

Factors that might cause actual results to differ from the results discussed in forward-looking statements include, but are not limited to, the risk factors in Item 1A, Risk Factors, in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2014 , and as may be described from time to time in the Corporation’s subsequent SEC filings.

Overview

The following discussion and analysis is presented to assist in the understanding and evaluation of the Corporation’s financial condition and results of operations. It is intended to complement the unaudited consolidated financial statements, footnotes, and supplemental financial data appearing elsewhere in this Form 10-Q and should be read in conjunction therewith. Management continually evaluates strategic acquisition opportunities and other various strategic alternatives that could involve the sale or acquisition of branches or other assets, or the consolidation or creation of subsidiaries.

During the third quarter of 2015, the Corporation reclassified approximately $500 million of closed end first lien home equity loans to residential mortgage loans in order to better align with the Corporation's regulatory reporting of residential mortgage loan products. All prior periods have been restated to reflect this change. All prior periods have been restated to reflect this change. As a result, the restated home equity loan portfolio is $1.1 billion for December 31, 2014 , compared to the originally reported amount of $1.6 billion . Similarly, the restated residential mortgage loan portfolio is $5.1 billion for December 31, 2014 , compared to the originally reported amount of $4.5 billion .

Performance Summary


•	Average loans of $18.5 billion for the third quarter of 2015 grew $264 million, or 1% from the second quarter of 2015, primarily driven by a $247 million increase in the residential mortgage loan portfolio. Average deposits grew to a record $20.3 billion, up $667 million, or 3% from the second quarter of 2015, primarily driven by strong growth in demand deposits and money market accounts.


•	Credit quality continued to improve with decreases in nonaccrual loans (down 8%) and net charge offs (down 8%) compared to the second quarter of 2015, while potential problem loans increased $64 million driven by the migration of a small number of commercial credits.


•	Net interest income of $171 million for the third quarter of 2015 increased $4 million, or 2% from the second quarter of 2015, while the net interest margin declined 1 basis point to 2.82%.


•	Noninterest income of $80 million for the third quarter of 2015 decreased $7 million, or 8% from the second quarter of 2015, primarily driven by reduced mortgage banking income and seasonally lower insurance activity.


•	Noninterest expense of $171 million for the third quarter of 2015 decreased $5 million, or 3% from the second quarter of 2015, primarily due to lower personnel and technology costs.

(a)	The efficiency ratio as defined by the Federal Reserve guidance is noninterest expense (which includes the provision for unfunded commitments) divided by the sum of net interest income plus noninterest income, excluding investment securities gains / losses, net.

(b)

The fully tax-equivalent efficiency ratio is noninterest expense (which includes the provision for unfunded commitments), excluding other intangible amortization, divided by the sum of taxable equivalent net interest income plus noninterest income, excluding investment securities gains / losses. Management believes the fully tax-equivalent efficiency ratio, which adjusts net interest income for the tax-favored status of certain loans and investment securities, to be the preferred industry measurement as it enhances the comparability of net interest income arising from taxable and tax-exempt sources. This presentation differs from our prior reporting. All periods have been adjusted to conform.

Table of Contents

Notable contributions to the change in net interest income were:

•

Net interest income on a taxable equivalent basis for the nine months ended September 30, 2015 , was $520 million , a decrease of $1 million versus the first nine months of 2014. The decrease in taxable equivalent net interest income was attributable to an unfavorable rate variance (as the impact of changes in the interest rate environment and product pricing decreased taxable equivalent net interest income by $44 million), partially offset by a favorable volume variance (as balance sheet changes in both volume and mix increased taxable equivalent net interest income by $43 million).


•	The net interest margin for the first nine months of 2015 was 2.84% , 25 bp lower than 3.09% for the same period in 2014. This comparable period decrease was comprised of a 26 bp decrease in interest rate spread (the net of a 16 bp decrease in yield on earning assets and a 10 bp increase in the cost of interest-bearing liabilities) and a 1 bp higher contribution from net free funds.


•	The Federal Reserve left interest rates unchanged through the first nine months of 2015. There remains uncertainty as to the timing of a potential interest rate change. As of September 30, 2015, the market was pricing less than a 50% probability of an increase by year end 2015.

•

The yield on earning assets was 3.16% for the first nine months of 2015, 16 bp lower than the comparable period last year. Loan yields were down 17 bp, (to 3.40% ), and are related to competitive pricing pressures in a low interest rate environment. The yield on investment securities and other short-term investments decreased 18 bp (to 2.44% ), and was also impacted by the low interest rate environment and higher prepayment speeds of mortgage-related securities purchased at a premium.


•	The rate on interest-bearing liabilities of 0.40% for the first nine months of 2015 was 10 bp higher than the same period in 2014. The cost of short-term funding was relatively flat, while the cost of long-term funding increased 46 bp (to 1.31% ), mainly due to the issuance of long-term senior and subordinated notes in late 2014.

•

Average earning assets were $24.4 billion for the first nine months of 2015, an increase of $1.9 billion (8%) from the comparable period last year. Average loans increased $1.5 billion, including increases in commercial loans (up $870 million) and residential mortgage loans (up $648 million), while retail loans decreased (down $18 million). Average investment securities and other short-term investments increased $405 million, primarily in municipal securities, mortgage related securities and interest-bearing deposits in other banks.

•

Average interest-bearing liabilities of $19.3 billion for the first nine months of 2015 increased $1.7 billion (10%) from the comparable period last year. Average interest-bearing deposits increased $2.1 billion (primarily in money market deposits), while noninterest bearing deposits increased $238 million. On average, short and long-term funding decreased $346 million between the comparable nine month periods, including a $668 million decrease in short-term funding, partially offset by a $322 million increase in long-term funding (also mainly due to the issuance of long-term senior and subordinated notes in late 2014).

Provision for Credit Losses

The provision for credit losses (which includes the provision for loan losses and the provision for unfunded commitments) was $18 million and $11 million for the first nine months of 2015 and 2014 , respectively. The provision for credit losses was $16 million for the full year 2014 . Net charge offs were $22 million for the first nine months of 2015 , compared to $11 million for the first nine months of 2014 and $15 million for the full year of 2014 . Annualized net charge offs as a percent of average loans for the first nine months of 2015 were 0.16% , compared to 0.08% for the first nine months of 2014 and 0.09% for the full year 2014 . See Tables 9 and 10.

The provision for credit losses is predominantly a function of the Corporation’s reserving methodology and judgments as to other qualitative and quantitative factors used to determine the appropriate level of the allowance for loan losses and allowance for unfunded commitments, which focuses on changes in the size and character of the loan portfolio, changes in levels of impaired and other nonaccrual loans, historical losses and delinquencies in each portfolio category, the level of loans sold or transferred to held for sale, the risk inherent in specific loans, concentrations of loans to specific borrowers or industries, existing economic conditions, the fair value of underlying collateral, and other factors which could affect potential credit losses. See additional discussion under sections “Credit Risk,” “Allowance for Credit Losses,” and “Nonaccrual Loans, Potential Problem Loans, and Other Real Estate Owned.”

* Fee income ratio is fee income, per the above table, divided by total revenue (defined as taxable equivalent net interest income plus fee income).

Notable contributions to the change in noninterest income were:

•

Core fee-based revenue was $193 million , an increase of $22 million ( 13% ) versus the nine months ended September 30, 2014 . Insurance commissions were $57 million , up $24 million ( 70% ) from the nine months ended September 30, 2014 . The increase in insurance commissions was primarily due to the acquisition of Ahmann & Martin Co. See Note 2, "Acquisition," of the notes to consolidated financial statements for additional information on the Ahmann & Martin Co. acquisition.

•

Net mortgage banking income was $24 million for the nine months ended September 30, 2015 and $18 million for the nine months ended September 30, 2014 . Net mortgage banking consists of gross mortgage banking income less mortgage servicing rights expense. Gross mortgage banking income includes servicing fees, the gain or loss on sales of mortgage loans to the secondary market, changes to the mortgage loan repurchase reserve, and the fair value adjustments on the mortgage derivatives. Gross mortgage banking income increased $6 million ( 23% ) compared to the nine months ended September 30, 2014 , primarily due to a $4 million increase in gain on sale and a $2 million favorable change in the fair value of the mortgage derivatives.


•	Bank owned life insurance income was $8 million , down $3 million from the nine months ended September 30, 2014 primarily due to death benefits received during the nine months ended September 30, 2014 . All remaining noninterest income categories on a combined basis increased $2 million from the first nine months of 2014.

Notable contributions to the change in noninterest expense were:

•

Personnel expense (which includes salary-related expenses and fringe benefit expenses) was $304 million for the nine months ended September 30, 2015 , up $11 million ( 4% ) from the nine months ended September 30, 2014 . Salary-related expenses increased $10 million (4%). This increase was primarily attributable to the Ahmann & Martin Co. acquisition which added approximately 110 colleagues during the first nine months of 2015. Fringe benefit expenses were relatively flat from the comparable period in 2014.

•

Nonpersonnel noninterest expenses on a combined basis were $218 million , up $4 million ( 2% ) from the nine months ended September 30, 2014 . Occupancy was up $3 million ( 7% ), related to a lease termination charge in the first quarter of 2015, as the Corporation further consolidated office space in Chicago. Technology was up $6 million ( 14% ), as the Corporation continues to invest in solutions that will drive operational efficiency. Foreclosure/OREO expense decreased $2 million ( 42% ) compared to the nine months ended September 30, 2014 , as credit quality continues to improve and foreclosures trend down. All remaining noninterest expense categories on a combined basis were down $3 million (2%) compared to the first nine months of 2014.

Income Taxes

Income tax expense recorded in the consolidated statements of income involves the interpretation and application of certain accounting pronouncements and federal and state tax laws and regulations, and is, therefore, considered a critical accounting policy. The Corporation is subject to examination by various taxing authorities. Examination by taxing authorities may impact the amount of tax expense and / or reserve for uncertain tax positions if their interpretations differ from those of management, based on their judgments about information available to them at the time of their examinations. See Note 10, “Income Taxes,” of the notes to consolidated financial statements and section “Critical Accounting Policies," for additional information on income taxes.

Balance Sheet

At September 30, 2015 , total assets were $27.5 billion , up $645 million ( 2% ) from December 31, 2014 . Loans of $18.5 billion at September 30, 2015 were up $931 million ( 5% ) from December 31, 2014 . See section "Credit Risk" for additional information on loans. Investment securities were $6.0 billion at September 30, 2015 , up slightly ( 4% ) from year-end 2014 .

Table of Contents

At September 30, 2015 , total deposits of $20.6 billion were up $1.8 billion ( 10% ) from December 31, 2014 . See section "Deposits" for additional information on deposits. Given the increase in deposits, short and long-term funding decreased $1.3 billion ( 26% ) since year-end 2014, primarily in long-term FHLB advances.

Credit Risk

Total loans were $18.5 billion at September 30, 2015 , an increase of $931 million or 5% from December 31, 2014 . Commercial and business loans were $7.1 billion , up $130 million ( 2% ) from December 31, 2014 , to represent 38% of total loans at September 30, 2015 . Commercial real estate lending totaled $4.3 billion at September 30, 2015 and represented 23% of total loans, an increase of $242 million ( 6% ) from December 31, 2014 . Consumer loans were $7.1 billion , up $559 million ( 9% ) from December 31, 2014 , and represented 39% of total loans at September 30, 2015 .

An active credit risk management process is used for commercial loans to ensure that sound and consistent credit decisions are made. Credit risk is controlled by detailed underwriting procedures, comprehensive loan administration, and periodic review of borrowers’ outstanding loans and commitments. Borrower relationships are formally reviewed and graded on an ongoing basis for early identification of potential problems. Further analyses by customer, industry, and geographic location are performed to monitor trends, financial performance, and concentrations.

Table of Contents

The Corporation has long-term guidelines relative to the proportion of Commercial and Business, Commercial Real Estate, and Consumer loans within the overall loan portfolio, with each targeted to represent 30-40% of the overall loan portfolio. The targeted long-term guidelines were unchanged during 2014 and the first nine months of 2015 . Furthermore, certain sub-asset classes within the respective portfolios were further defined and dollar limitations were placed on these sub-portfolios. These guidelines and limits are reviewed quarterly and approved annually by the Enterprise Risk Committee of the Corporation’s Board of Directors. These guidelines and limits are designed to create balance and diversification within the loan portfolios.

Commercial and business lending

The commercial and business lending classification primarily includes commercial loans to large corporations, middle market companies and small businesses. At September 30, 2015 , the largest industry groups within the commercial and business lending category included the manufacturing sector which represented 8% of total loans and 21% of the total commercial and business lending portfolio. The next largest industry groups within the commercial and business lending category were the Finance and Insurance sector and Mining, which each represented 4% of total loans and 11% of the total commercial and business lending portfolio at September 30, 2015 . The remaining portfolio is spread over a diverse range of industries, none of which exceeds 4% of total loans. The credit risk related to commercial loans is largely influenced by general economic conditions and the resulting impact on a borrower’s operations or on the value of underlying collateral, if any.

Commercial real estate lending

Commercial real estate lending primarily includes commercial-based loans to investors that are secured by commercial income properties or multi-family projects. Commercial real estate loans are typically intermediate to long-term financings. Loans of this type are mainly secured by commercial income properties or multi-family projects. Credit risk is managed in a similar manner to commercial and business lending by employing sound underwriting guidelines, lending primarily to borrowers in local markets and businesses, periodically evaluating the underlying collateral, and formally reviewing the borrower’s financial soundness and relationship on an ongoing basis.

Real estate construction

Real estate construction loans are primarily short-term or interim loans that provide financing for the acquisition or development of commercial income properties, multi-family projects or residential development, both single family and condominium. Real estate construction loans are made to developers and project managers who are generally well known to the Corporation, and have prior successful project experience. The credit risk associated with real estate construction loans is generally confined to specific geographic areas but is also influenced by general economic conditions. The Corporation controls the credit risk on these types of loans by making loans in familiar markets to developers, reviewing the merits of individual projects, controlling loan structure, and monitoring project progress and construction advances.

The Corporation’s current lending standards for commercial real estate and real estate construction lending are determined by property type and specifically address many criteria, including: maximum loan amounts, maximum loan-to-value (“LTV”), requirements for pre-leasing and / or presales, minimum borrower equity, and maximum loan to cost. Currently, the maximum standard for LTV is 80%, with lower limits established for certain higher risk types, such as raw land which has a 50% LTV maximum. The Corporation’s LTV guidelines are in compliance with regulatory supervisory limits. In most cases, for real estate construction loans, the loan amounts include interest reserves, which are built into the loans and sized to fund loan payments through construction and lease up and / or sell out.

Residential mortgage

Residential mortgage loans are primarily first lien home mortgages with a maximum loan to collateral value without credit enhancement (e.g. private mortgage insurance) of 80%. As part of management’s historical practice of originating and servicing residential mortgage loans, generally the Corporation’s 30-year, fixed-rate, conforming residential real estate mortgage loans are sold in the secondary market with servicing rights retained. The majority of the on balance sheet residential mortgage portfolio consists of hybrid, adjustable rate mortgage loans with initial fixed rate terms of 3, 5, 7, or 10 years. The Corporation occasionally retains a portion of its originated 15-year and under, fixed-rate residential real estate mortgages in its loan portfolio. At September 30, 2015 , the residential mortgage portfolio was comprised of $1.8 billion of fixed-rate residential real estate mortgages and $3.9 billion of adjustable-rate residential real estate mortgages.

The Corporation’s underwriting and risk-based pricing guidelines for residential mortgage loans include minimum borrower FICO and maximum LTV of the property securing the loan. Residential mortgage products generally are underwritten using FHLMC and FNMA secondary marketing guidelines.

Table of Contents

Home equity

Our home equity lending portfolio consists of both home equity lines of credit and closed-end home equity loans. The Corporation’s credit risk monitoring guidelines for home equity lending is based on an ongoing review of loan delinquency status, as well as a quarterly review of FICO score deterioration and property devaluation. The Corporation does not routinely obtain appraisals on performing loans to update LTV ratios after origination; however, the Corporation monitors the local housing markets by reviewing the various home price indices and incorporates the impact of the changing market conditions in its ongoing credit monitoring process. For junior lien home equity loans, the Corporation is unable to track the performance of the first lien loan if it does not own or service the first lien loan. However, the Corporation obtains a refreshed FICO score on a quarterly basis and monitors this as part of its assessment of the home equity portfolio. Loans and lines in a junior position at September 30, 2015 included approximately 43% for which the Corporation also owned or serviced the related first lien loan and approximately 57% where the Corporation did not service the related first lien loan.

The Corporation’s underwriting and risk-based pricing guidelines for home equity lines and loans consist of a combination of both borrower FICO and the original LTV of the property securing the loan. Currently, for home equity products, the maximum acceptable LTV is 90% for customers with FICO scores exceeding 700. Home equity loans generally have a 20 year term and are fixed rate with principal and interest payments required, while home equity lines are generally variable rate, interest only lines of credit which do not require the payment of principal during the initial revolving period, after which principal payments are required. Based upon outstanding balances at September 30, 2015 , the following table presents the periods when home equity lines of credit revolving periods are scheduled to end.

Installment and credit cards

Installment and credit cards consist of student loans, short-term and other personal installment loans and credit cards. Credit risk for non-government guaranteed student, short-term and personal installment loans and credit cards is generally influenced by general economic conditions, the characteristics of individual borrowers, and the nature of the loan collateral. Risks of loss are generally on smaller average balances per loan spread over many borrowers. Once charged off, there is usually less opportunity for recovery on these smaller retail loans. Credit risk is primarily controlled by reviewing the creditworthiness of the borrowers, monitoring payment histories, and taking appropriate collateral and guarantee positions. The student loan portfolio is in run-off and no new student loans are being originated.

The loan portfolio is widely diversified by types of borrowers, industry groups, and market areas within our core footprint. Significant loan concentrations are considered to exist when there are amounts loaned to numerous borrowers engaged in similar activities that would cause them to be similarly impacted by economic or other conditions. At September 30, 2015 , no significant concentrations existed in the Corporation’s portfolio in excess of 10% of total loans.

Credit risks within the loan portfolio are inherently different for each loan type. Credit risk is controlled and monitored through the use of lending standards, a thorough review of potential borrowers, and ongoing review of loan payment performance. Active asset quality administration, including early problem loan identification and timely resolution of problems, aids in the management of credit risk and minimization of loan losses. Credit risk management for each loan type is discussed briefly in the section entitled “Credit Risk.”

Table of Contents

The allowance for credit losses is comprised of the allowance for loan losses and the allowance for unfunded commitments. The level of the allowance for loan losses represents management’s estimate of an amount appropriate to provide for probable credit losses in the loan portfolio at the balance sheet date. The allowance for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to unfunded credit facilities (including unfunded loan commitments and letters of credit) and is included in accrued expenses and other liabilities on the consolidated balance sheets.

In general, the change in the allowance for credit losses is a function of a number of factors, including but not limited to changes in the loan portfolio (see Table 5), net charge offs (see Table 9) and nonperforming assets (see Table 10). To assess the appropriateness of the allowance for loan losses, an allocation methodology is applied by the Corporation which focuses on an evaluation of facts and issues related to specific loans, management’s ongoing review and grading of the loan portfolio, consideration of historical loan loss and delinquency experience on each portfolio category, trends in past due and nonaccrual loans, the level of potential problem loans, the risk characteristics of the various classifications of loans, changes in the size and character of the loan portfolio, concentrations of loans to specific borrowers or industries, existing economic conditions, the fair value of underlying collateral, and other qualitative and quantitative factors which could affect potential credit losses. Assessing these factors involves significant judgment. While management uses currently available information to recognize losses on loans, future adjustments to the allowance for loan losses may be necessary based on newly received appraisals, updated commercial customer financial statements, rapidly deteriorating customer cash flow, and changes in economic conditions that affect our customers. Management considers the allowance for loan losses a critical accounting policy (see section “Critical Accounting Policies”), as assessing these numerous factors involves significant judgment.

The methodology used for the allowance for loan losses at September 30, 2015 and December 31, 2014 was generally comparable, whereby the Corporation segregated its loss factors (used for both criticized and non-criticized loan categories) into a component primarily based on historical loss rates and a component primarily based on other qualitative factors that are probable to affect loan collectability. The Corporation's allowance for loan losses methodology considers an estimate of the historical loss emergence period (which is the period of time between the event that triggers a loss and the confirmation and / or charge off of that loss). Management allocates the allowance for loan losses by pools of risk within each loan portfolio. The allocation methodology consists of the following components: First, a valuation allowance estimate is established for specifically identified commercial and consumer loans determined by the Corporation to be impaired, using discounted cash flows, estimated fair value of underlying collateral, and / or other data available. Second, management allocates the allowance for loan losses with loss factors, for criticized loan pools by loan type as well as for non-criticized loan pools by loan type, primarily based on historical loss rates after considering loan type, historical loss and delinquency experience, and industry statistics. Loans that have been criticized are considered to have a higher risk of default than non-criticized loans, as circumstances were present to support the lower loan grade, warranting higher loss factors. The loss factors applied in the methodology are periodically re-evaluated and adjusted to reflect changes in historical loss levels or other risks. Lastly, management allocates the allowance for loan losses to absorb unrecognized losses that may not be provided for by the other components due to other factors evaluated by management, such as limitations within the credit risk grading process, known current economic or business conditions that may not yet show in trends, industry or other concentrations with current issues that impose higher inherent risks than are reflected in the loss factors, and other relevant considerations. Because each of the criteria used is subject to change, the allocation of the allowance for loan losses is made for analytical purposes and is not necessarily indicative of the trend of future loan losses in any particular category. The total allowance for loan losses is available to absorb losses from any segment of the loan portfolio.

The methodology used for the allowance for unfunded commitments at September 30, 2015 and December 31, 2014 was also generally comparable. The determination of the appropriate level of the allowance for unfunded commitments is based on management's evaluation of the unfunded credit facilities, including an assessment of historical commitment utilization experience and credit risk grading of the loan.

At September 30, 2015 , the allowance for credit losses was $286 million compared to $291 million at both September 30, 2014 , and December 31, 2014 . At September 30, 2015 , the allowance for loan losses to total loans was 1.42% and covered 178% of nonaccrual loans, compared to 1.55% and 145% , respectively, at September 30, 2014 , and 1.51% and 150% , respectively, at December 31, 2014 . Tables 9 and 10 provide additional information regarding activity in the allowance for credit losses, impaired loans, and nonperforming assets. See Note 7, “Loans, Allowance for Credit Losses, and Credit Quality,” of the notes to consolidated financial statements for additional allowance for credit losses disclosures.

Management believes the level of allowance for loan losses and allowance for unfunded commitments to be appropriate at September 30, 2015 and December 31, 2014 .

Table of Contents

Management is committed to a proactive nonaccrual and problem loan identification philosophy. This philosophy is implemented through the ongoing monitoring and review of all pools of risk in the loan portfolio to ensure that problem loans are identified quickly and the risk of loss is minimized. Table 10 provides detailed information regarding nonperforming assets, which include nonaccrual loans and other real estate owned.

Nonaccrual Loans

Nonaccrual loans are considered one indicator of potential future loan losses. See also Note 7, "Loans, Allowance for Credit Losses, and Credit Quality," of the notes to consolidated financial statements for additional nonaccrual loan disclosures. The ratio of nonaccrual loans to total loans was 0.80% at September 30, 2015 , compared to 1.07% at September 30, 2014 and 1.01% at December 31, 2014 .

Accruing Loans Past Due 90 Days or More

Loans past due 90 days or more but still accruing interest are classified as such where the underlying loans are both well secured (the collateral value is sufficient to cover principal and accrued interest) and are in the process of collection. Accruing loans 90 days or more past due at September 30, 2015 , were relatively unchanged from both September 30, 2014 and December 31, 2014 .

Troubled Debt Restructurings (“Restructured Loans”)

Loans are considered restructured loans if concessions have been granted to borrowers that are experiencing financial difficulty. See also Note 7, "Loans, Allowance for Credit Losses, and Credit Quality," of the notes to consolidated financial statements for management's accounting policy for restructured loans and for additional disclosures on restructured loans.

Potential Problem Loans

The level of potential problem loans is another predominant factor in determining the relative level of risk in the loan portfolio and in determining the appropriate level of the allowance for loan losses. Potential problem loans are generally defined by management to include loans rated as substandard by management but that are not considered impaired (i.e., nonaccrual loans and accruing troubled debt restructurings); however, there are circumstances present to create doubt as to the ability of the borrower to comply with present repayment terms. The decision of management to include performing loans in potential problem loans does not necessarily mean that the Corporation expects losses to occur, but that management recognizes a higher degree of risk associated with these loans. The loans that have been reported as potential problem loans are predominantly commercial loans covering a diverse range of businesses and real estate property types.

Other Real Estate Owned

Other real estate owned was $14 million at September 30, 2015 , compared to $17 million at both September 30, 2014 and December 31, 2014 , respectively. Management actively seeks to ensure properties held are monitored to minimize the Corporation’s risk of loss.

Liquidity

The objective of liquidity management is to ensure that the Corporation has the ability to generate sufficient cash or cash equivalents in a timely and cost-effective manner to satisfy the cash flow requirements of depositors and borrowers and to meet its other commitments as they fall due, including the ability to pay dividends to shareholders, service debt, invest in subsidiaries or acquisitions, and satisfy other operating requirements. In addition to satisfying cash flow requirements in the ordinary course of business, the Corporation actively monitors and manages its liquidity position to ensure sufficient resources are available to meet cash flow requirements in adverse situations.

The Corporation’s internal liquidity management framework includes measurement of several key elements, such as deposit funding as a percent of total assets and liquid asset levels. Strong capital ratios, credit quality, and core earnings are essential to maintaining cost-effective access to wholesale funding markets. A downgrade or loss in credit ratings could have an impact on the Corporation’s ability to access wholesale funding at favorable interest rates. In addition to static liquidity measures, the Corporation performs dynamic scenario analysis in accordance with industry best practices. Measures have been established to ensure the Corporation has sufficient high quality short-term liquidity to meet cash flow requirements under stressed scenarios. At September 30, 2015 , the Corporation was in compliance with its internal liquidity objectives.

Credit ratings relate to the Corporation’s ability to issue debt securities and the cost to borrow money, and should not be viewed as an indication of future stock performance or a recommendation to buy, sell, or hold securities. Among other factors, the credit ratings are based on financial strength, credit quality and concentrations in the loan portfolio, the level and volatility of earnings, capital adequacy, the quality of management, the liquidity of the balance sheet, the availability of a significant base of core deposits,

Table of Contents

and the Corporation’s ability to access a broad array of wholesale funding sources. Adverse changes in these factors could result in a negative change in credit ratings and impact not only the ability to raise funds in the capital markets but also the cost of these funds. Ratings are subject to revision or withdrawal at any time and each rating should be evaluated independently. During May 2015, Moody's upgraded the credit ratings of the Parent Company and its subsidiary bank. These upgraded credit ratings are reflected below.

Bank short-term	P1	—
Bank long-term	A1	BBB+
Parent Company short-term	P2	—
Parent Company long-term	Baa1	BBB
Outlook	Stable	Stable

The Corporation also has multiple funding sources that could be used to increase liquidity and provide additional financial flexibility. The Parent Company has filed a shelf registration with the SEC under which the Parent Company may, from time to time, offer shares of the Corporation’s common stock in connection with acquisitions of businesses, assets or securities of other companies. The Parent Company has also filed a universal shelf registration statement, under which the Parent Company may offer securities, either separately or in units: debt securities, preferred stock, depositary shares, common stock, and warrants. The Parent Company also has a $200 million commercial paper program, of which, $60 million was outstanding at September 30, 2015 . Dividends and service fees from subsidiaries and proceeds from issuance of capital are also funding sources for the Parent Company.

The Bank has established federal funds lines with counterparty banks and has the ability to borrow from the Federal Home Loan Bank of Chicago ( $2.0 billion of Federal Home Loan Bank advances were outstanding at September 30, 2015 ). The Bank also has significant excess investment securities collateral and pledged loan capacity which could be utilized to secure additional deposits, repurchase agreements, or Federal Home Loan Bank advances as necessary. The Bank may also issue institutional certificates of deposit, network transaction deposits, and brokered certificates of deposit.

Investment securities are an important tool to the Corporation’s liquidity objective. As of September 30, 2015 , the majority of investment securities were classified as available for sale, with only a portion of municipal securities classified as held to maturity. Of the $6.0 billion investment securities portfolio at September 30, 2015 , a portion of these securities were pledged to secure collateralized deposits and repurchase agreements and for other purposes as required or permitted by law. The majority of the remaining investment securities of $2.2 billion could be pledged or sold to enhance liquidity, if necessary.

For the nine months ended September 30, 2015 , net cash provided by operating activities and financing activities was $239 million and $412 million , respectively, while net cash used in investing activities was $1.3 billion , for a net decrease in cash and cash equivalents of $622 million since year-end 2014 . During the first nine months of 2015, loans and investment securities increased $931 million and $207 million, respectively. On the funding side, deposits increased $1.8 billion, while long-term funding decreased $1.3 billion. The Corporation also repurchased $93 million of common stock and paid cash dividends to stockholders of $51 million during the first nine months of 2015.

For the nine months ended September 30, 2014 , net cash provided by operating activities and financing activities was $131 million and $1.3 billion, respectively, while net cash used in investing activities was $1.5 billion, for a net decrease in cash and cash equivalents of $128 million since year-end 2013 . During the first nine months of 2014 , loans increased $1.3 billion and investment securities increased $222 million. On the funding side, deposits increased $934 million and short-term funding increased $689 million, while long-term funding decreased $156 million. The Corporation also repurchased $163 million of common stock and paid cash dividends to stockholders of $47 million during the first nine months of 2014.

Quantitative and Qualitative Disclosures about Market Risk

Market risk and interest rate risk are managed centrally. Market risk is the potential for loss arising from adverse changes in the fair value of fixed income securities, equity securities, other earning assets and derivative financial instruments as a result of changes in interest rates or other factors. Interest rate risk is the potential for reduced net interest income resulting from adverse changes in the level of interest rates. As a financial institution that engages in transactions involving an array of financial products, the Corporation is exposed to both market risk and interest rate risk. In addition to market risk, interest rate risk is measured and managed through a number of methods. The Corporation uses financial modeling simulation techniques that measure the sensitivity of future earnings due to changing rate environments to measure interest rate risk.

Policies established by the Corporation’s Asset / Liability Committee (“ALCO”) and approved by the Board of Directors are intended to manage these risks. The Board has delegated day-to-day responsibility for managing market and interest rate risk to

ALCO. The primary objectives of market risk management is to minimize any adverse effect that changes in market risk factors may have on net interest income and to offset the risk of price changes for certain assets recorded at fair value.

Interest Rate Risk

The primary goal of interest rate risk management is to control exposure to interest rate risk, within policy limits approved by the Board of Directors. These limits and guidelines reflect our tolerance for interest rate risk over both short-term and long-term horizons. No limit breaches occurred during the first nine months of 2015.

The major sources of our non-trading interest rate risk are timing differences in the maturity and re-pricing characteristics of assets and liabilities, changes in the shape of the yield curve, and the potential exercise of explicit or embedded options. We measure these risks and their impact by identifying and quantifying exposures through the use of sophisticated simulation and valuation models, which, as described in additional detail below, are employed by management to understand net interest income (NII) at risk, interest rate sensitive earnings at risk (EAR), and market value of equity (MVE) at risk. These measures show that our interest rate risk profile was slightly asset sensitive at September 30, 2015 .

MVE and EAR are complementary interest rate risk metrics and should be viewed together. Net interest income and EAR sensitivity capture asset and liability re-pricing mismatches for the first year inclusive of forecast balance sheet changes and are considered shorter term measures, while MVE sensitivity captures mismatches within the period end balance sheets through the financial instruments’ respective maturities and is considered a longer term measure.

A positive NII and EAR sensitivity in a rising rate environment indicates that over the forecast horizon of one year, asset based income will increase more quickly than liability based expense due to the balance sheet composition. A negative MVE sensitivity in a rising rate environment indicates that the value of financial assets will decrease more than the value of financial liabilities.

One of the primary methods that we use to quantify and manage interest rate risk is simulation analysis, which we use to model net interest income from assets, liabilities, and derivative positions under various interest rate scenarios and balance sheet structures. As the future path of interest rates cannot be known, we use simulation analysis to project rate sensitive income under various scenarios including implied forward and deliberately extreme and perhaps unlikely scenarios. The analyses may include rapid and gradual ramping of interest rates, rate shocks, basis risk analysis, and yield curve twists. Specific strategies are also analyzed to determine their impact on net interest income levels and sensitivities.

Key assumptions in the simulation analysis (and in the valuation analysis discussed below) relate to the behavior of interest rates and spreads, the changes in product balances, and the behavior of loan and deposit clients in different rate environments. This analysis incorporates several assumptions, the most material of which relate to the re-pricing characteristics and balance fluctuations of deposits with indeterminate or non-contractual maturities.

The sensitivity analysis included below is measured as a percentage change in net interest income and EAR due to instantaneous moves in benchmark interest rates. Estimated changes set forth below are dependent upon material assumptions such as those previously discussed. We evaluate the sensitivity using: 1) a dynamic forecast incorporating expected growth in the balance sheet, and 2) a static forecast where the current balance sheet is held constant.

TABLE 11

Estimated % Change in Rate Sensitive Earnings at Risk (EAR) Over 12 Months



	Dynamic Forecast		Static Forecast		Dynamic Forecast		Static Forecast
Instantaneous Rate Change	September 30, 2015		September 30, 2015		December 31, 2014		December 31, 2014
100 bp increase in interest rates	1.2	%	1.2	%	1.6	%	2.8	%
200 bp increase in interest rates	2.6	%	3.0	%	3.4	%	5.3	%

We also perform valuation analysis, which we use for discerning levels of risk present in the balance sheet and derivative positions that might not be taken into account in the net interest income simulation analysis. Whereas NII and EAR simulation highlights exposures over a relatively short time horizon, valuation analysis incorporates all cash flows over the estimated remaining life of all balance sheet and derivative positions. The valuation of the balance sheet, at a point in time, is defined as the discounted present value of asset cash flows and derivative cash flows minus the discounted present value of liability cash flows, the net of which is referred to as MVE. The sensitivity of MVE to changes in the level of interest rates is a measure of the longer-term re-pricing risk and options risk embedded in the balance sheet. Similar to the net interest income simulation, MVE uses instantaneous changes in rates. However, MVE values only the current balance sheet and does not incorporate the growth assumptions that are used in the NII and EAR simulations. As with NII and EAR simulations, assumptions about the timing and variability of balance sheet

Table of Contents

cash flows are critical in the MVE analysis. Particularly important are the assumptions driving prepayments and the expected changes in balances and pricing of the indeterminate deposit portfolios. At September 30, 2015 , the MVE profile indicates a decline in net balance sheet value due to instantaneous upward changes in rates. MVE sensitivity is reported in both upward and downward rate shocks.

TABLE 12

Market Value of Equity Sensitivity



Instantaneous Rate Change	September 30, 2015		December 31, 2014
100 bp increase in interest rates	(2.0	)%	(1.0	)%
200 bp increase in interest rates	(4.4	)%	(2.5	)%

The increased MVE sensitivity from December 31, 2014 is primarily attributable to being closer to the redemption date of $430 million of senior notes. While an instantaneous and severe shift in interest rates was used in this analysis to provide an estimate of exposure under an extremely adverse scenario, we believe that a gradual shift in interest rates would have a much more modest impact. Since MVE measures the discounted present value of cash flows over the estimated lives of instruments, the change in MVE does not directly correlate to the degree that earnings would be impacted over a shorter time horizon (i.e., the current year). Further, MVE does not take into account factors such as future balance sheet growth, changes in product mix, changes in yield curve relationships, and changing product spreads that could mitigate the adverse impact of changes in interest rates. The net interest income simulation and valuation analyses do not include actions that management may undertake to manage this risk in response to anticipated changes in interest rates.

The Corporation utilizes a variety of financial instruments in the normal course of business to meet the financial needs of its customers and to manage its own exposure to fluctuations in interest rates. These financial instruments include lending-related commitments and derivative instruments. A discussion of the Corporation’s derivative instruments at September 30, 2015 , is included in Note 11, “Derivative and Hedging Activities,” of the notes to consolidated financial statements. A discussion of the Corporation’s lending-related commitments is included in Note 13, “Commitments, Off-Balance Sheet Arrangements, and Contingent Liabilities,” of the notes to consolidated financial statements. See also Note 9, “Short and Long-Term Funding,” of the notes to consolidated financial statements for additional information on the Corporation’s short-term and long-term funding.

Table 13 summarizes significant contractual obligations and other commitments at September 30, 2015 , at those amounts contractually due to the recipient, including any premiums or discounts, hedge basis adjustments, or other similar carrying value adjustments.

Capital

Stockholders’ equity at September 30, 2015 was $3.0 billion , up $154 million from December 31, 2014 . In June 2015, the Corporation received net proceeds of $63 million from the issuance of 2.6 million depositary shares, each representing a 1/40th interest in a share of 6.125% Non-Cumulative Perpetual Preferred Stock, Series C. Cash dividends of $0.30 per share were paid in the first nine months of 2015 and cash dividends of $0.27 per share were paid in the first nine months of 2014.

Management actively reviews capital strategies for the Corporation and each of its subsidiaries in light of perceived business risks, future growth opportunities, industry standards, and compliance with regulatory requirements. The assessment of overall capital adequacy depends on a variety of factors, including asset quality, liquidity, stability of earnings, changing competitive forces, economic condition in markets served, and strength of management. The capital ratios of the Corporation and its bank subsidiary were in excess of regulatory minimum requirements. The Corporation’s capital ratios are summarized in Table 14.

During the first nine months of 2015 , the Corporation repurchased $93 million , or approximately 5.0 million shares of common stock, at an average cost of $18.73 per share. The Corporation also repurchased $1.3 million , or approximately 50,000 depositary shares, each representing a 1/40th interest in a share of 8.00% Perpetual Preferred Stock, Series B, during the first nine months of 2015 . See Part II, Item 2, "Unregistered Sales of Equity Securities and Use of Proceeds," for additional information on the shares repurchased during the third quarter of 2015 . The repurchase of shares will be based on market and investment opportunities, capital levels, growth prospects, and regulatory constraints. Such repurchases may occur from time to time in open market purchases, block transactions, private transactions, accelerated share repurchase programs, or similar facilities.

In July 2013, the Federal Reserve Board ("FRB") and the Office of the Comptroller of the Currency ("OCC") issued final rules establishing a new comprehensive capital framework for U.S. banking organizations that would implement the Basel III capital framework. Under the final rules, minimum requirements will increase for both the quantity and quality of capital held by the Corporation. The rules include a new common equity Tier 1 capital to risk weighted assets minimum ratio of 4.5%, raise the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0% to 6.0%, require a minimum ratio of Total Capital to risk-weighted assets of 8.0%, and require a minimum Tier 1 leverage ratio of 4.0%. A new capital conservation buffer, comprised of common equity Tier 1 capital, was also established above the regulatory minimum capital requirements. This capital conservation buffer will be phased in beginning January 1, 2016. The final rules also revise the definition and calculation of Tier 1 capital, Total Capital, and risk-weighted assets.

The phase-in period for the final rules became effect for the Corporation on January 1, 2015, with full compliance with all of the final rules' requirements phased in over a multi-year schedule, to be fully phased-in by January 1, 2019. As of September 30, 2015 , the Corporation's capital levels remained characterized as "well-capitalized" under the new rules.

The ratios tangible common equity to tangible assets and tangible equity to tangible assets exclude goodwill and other intangible assets, which is a non-GAAP financial measure. These financial measures have been included as they are considered to be critical metrics with which to analyze and evaluate financial condition and capital strength. See Note 8 for additional information on goodwill, core deposit intangibles, and other intangibles.


(2)	Tangible common equity is defined as common stockholders’ equity excluding goodwill, core deposit intangibles, and other intangible assets. Tangible assets is defined as total assets excluding goodwill, core deposit intangibles, and other intangibles.

(3)

The FRB establishes capital adequacy requirements, including well-capitalized standards for the Corporation. The OCC establishes similar capital adequacy requirements and standards for the Bank. Regulatory capital primarily consists of Tier 1 risk-based capital and Tier 2 risk-based capital. The sum of Tier 1 risk-based capital and Tier 2 risk-based capital equals our total risk-based capital. Risk-based capital guidelines require a minimum level of capital as a percentage of risk-weighted assets. Risk-weighted assets consist of total assets plus certain off-balance sheet and market items, subject to adjustment for predefined credit risk factors. Prior to 2015, the regulatory capital requirements effective for the Corporation followed the Capital Accord of the Basel Committee on Banking Supervision ("Basel I"). Beginning January 1, 2015, the regulatory capital requirements effective for the Corporation follow Basel III, subject to certain transition provisions from Basel I over the next three years to full implementation by January 1, 2018.

(4)

Common equity Tier 1, a non-GAAP financial measure, is used by banking regulators, investors and analysts to assess and compare the quality and composition of our capital with the capital of other financial services companies. Management uses Common equity Tier 1, along with other capital measures, to assess and monitor our capital position. Common equity Tier 1 for 2015 follows Basel III and is defined as common stock and related surplus, net of treasury stock, plus retained earnings. Common equity Tier 1 for 2014 follows Basel I and is defined as Tier 1 capital excluding qualifying perpetual preferred stock and qualifying trust preferred securities.

Comparable Third Quarter Results

The Corporation recorded net income of $49 million for the third quarter of 2015 , compared to net income of $50 million for the third quarter of 2014 . Net income available to common equity was $47 million for the third quarter of 2015 , or net income of $0.31 for both basic and diluted earnings per common share. Comparatively, net income available to common equity for the third quarter of 2014 , was $49 million , or net income of $0.31 for both basic and diluted earnings per common share (see Table 1).

Taxable equivalent net interest income for the third quarter of 2015 was $176 million , $2 million lower than the third quarter of 2014 (see Table 2). Changes in the rate environment decreased net interest income by $15 million while changes in the balance sheet volume and mix increased taxable equivalent net interest income by $13 million. The Federal funds target rate was unchanged for both quarters. The net interest margin between the comparable quarters was down 24 bp, to 2.82% in the third quarter of 2015 . Average earning assets increased $1.7 billion to $24.8 billion in the third quarter of 2015 , with average loans up $1.3 billion (predominantly in commercial loans and residential mortgages). On the funding side, average interest-bearing deposits were up $2.1 billion (primarily money market deposits), while average short and long-term funding was down $696 million primarily due to decreases in short and long-term FHLB advances partially offset by increases due to the issuance of long-term senior and subordinated notes in late 2014.

Nonaccrual loans declined to $147 million ( 0.80% of total loans) at September 30, 2015 , compared to $184 million ( 1.07% of total loans) at September 30, 2014 (see Table 10). Compared to the third quarter of 2014 , potential problem loans were up 20% to $264 million . The provision for credit losses was $8 million for the third quarter of 2015 , up $7 million compared to the third quarter of 2014 (see Table 9). Annualized net charge offs represented 0.17% of average loans for the third quarter of 2015 compared to 0.06% for the third quarter of 2014 . The allowance for loan losses to loans at September 30, 2015 was 1.42% , compared to 1.55% at September 30, 2014 . See discussion under sections, “Provision for Credit Losses,” “Allowance for Credit Losses,” and “Nonaccrual Loans, Potential Problem Loans, and Other Real Estate Owned.”

Noninterest income for the third quarter of 2015 increased $5 million ( 7% ) to $80 million versus the third quarter of 2014 . Core fee-based revenue increased $9 million primarily in insurance commissions attributable to the acquisition of Ahmann & Martin Co. (See Note 2, "Acquisition" of the notes to consolidated financial statements for additional information on the Ahmann & Martin Co. acquisition.) Net investment securities gains increased $3 million , primarily due to the continued restructuring of the investment portfolio. (See Note 6, "Investment Securities" of the notes to consolidated financial statements for additional information on the investment securities portfolio restructuring.) Partially offsetting these favorable variances were decreases of $5 million in net asset gains due to two corporate real estate gains during the third quarter of 2014 , and a $1 million decrease in BOLI income due to death benefits received in the third quarter of 2014 .

On a comparable quarter basis, noninterest expense was relatively unchanged at $171 million . Personnel expense increased $3 million compared to the third quarter of 2014, primarily attributable to the acquisition of Ahmann & Martin Co. Technology increased $1 million as we continue to invest in solutions that will drive operational efficiency. Business development and advertising decreased $2 million due to the timing of brand advertising campaigns, while foreclosure / OREO expense was down $2 million versus the comparable quarter in 2014 as credit quality continues to improve and foreclosures trend down.

The Corporation recognized income tax expense of $22 million for the third quarter of 2015 , compared to income tax expense of $24 million for third quarter of 2014 . The effective tax rate was 30.36% and 32.77% for the third quarter of 2015 and 2014, respectively.

Sequential Quarter Results

The Corporation recorded net income of $49 million for both the third quarter of 2015 and the second quarter of 2015 . Net income available to common equity was $47 million for the third quarter of 2015 or net income of $0.31 for both basic and diluted earnings per common share. Comparatively, net income available to common equity for the second quarter of 2015 , was $48 million, or net income of $0.32 for basic earnings per common share and $0.31 for diluted earnings per common share (see Table 1).

Taxable equivalent net interest income for third quarter of 2015 was $176 million, $4 million higher than the second quarter of 2015 due to a $4 million increase in net interest income from changes in the balance sheet volume and mix, a $1 million increase in net interest income related to the day count difference between the quarters, and a $1 million decrease in net interest income from changes in the rate environment and product pricing. The Federal funds target rate was unchanged for both quarters. The net interest margin in the third quarter of 2015 was down 1 bp, to 2.82% . Average earning assets increased $568 million to $24.8 billion in the third quarter of 2015 , with average loans up $264 million and average investments and other short-term investments up $304 million (primarily in mortgage related and municipal securities). On the funding side, average interest-bearing deposits were up $384 million (primarily money market deposits) and noninterest bearing demand deposits were up $283 million, while average short and long-term funding was down $150 million (primarily FHLB advances).

Table of Contents

Nonaccrual loans were $147 million ( 0.80% of total loans) at September 30, 2015 , compared to $160 million ( 0.88% of total loans) at June 30, 2015 (see Table 10). Potential problem loans increased to $264 million , up $64 million from the second quarter of 2015 . The provision for credit losses for the third quarter of 2015 was $8 million , up $3 million from second quarter of 2015 (see Table 9). Annualized net charge offs represented 0.17% of average loans for the third quarter of 2015 compared to 0.19% for the of 2015. The allowance for loan losses to loans at September 30, 2015 was 1.42% , compared to 1.43% at June 30, 2015 (see Table 10). See discussion under sections, “Provision for Credit Losses,” “Allowance for Credit Losses,” and “Nonaccrual Loans, Potential Problem Loans, and Other Real Estate Owned.”

Noninterest income for the third quarter of 2015 decreased $7 million (8%) to $80 million versus the second quarter of 2015 . Core fee-based revenue decreased $2 million (4%) from the second quarter of 2015, primarily due to seasonally lower insurance commissions. Net mortgage banking income was $7 million, down $3 million from the second quarter of 2015 , primarily driven by a $5 million net change in the quarter end mark-to-market of the residential mortgage pipeline due to interest rate movements.

On a sequential quarter basis, noninterest expense decreased $5 million (3%) to $171 million. Personnel expense was $101 million for the third quarter of 2015 , down $2 million (2%) from the second quarter of 2015 primarily due to lower severance expense. Technology decreased $2 million from the second quarter related to the completion of several projects. All remaining noninterest expense categories on a combined basis were down $2 million (3%) compared to second quarter of 2015 .

For both the third and second quarter of 2015 , the Corporation recognized income tax expense of $22 million. The effective tax rate was 30.36% and 30.61% for the third quarter of 2015 and the second quarter of 2015 , respectively.

Segment Review

As discussed in Note 16, “Segment Reporting,” of the notes to consolidated financial statements, the Corporation’s reportable segments have been determined based upon its internal profitability measurement system, which is organized by strategic business unit. Certain strategic business units have been combined for segment information reporting purposes where the nature of the products and services, the type of customer, and the distribution of those products and services are similar. The reportable segments are Corporate and Commercial Specialty; Community, Consumer and Business; and Risk Management and Shared Services.

Year to Date Segment Review

The Corporate and Commercial Specialty segment consists of lending and deposit solutions to larger businesses, developers, non-profits, municipalities, and financial institutions, and the support to deliver, fund, and manage such banking solutions. The Corporate and Commercial Specialty segment had net income of $85 million for the first nine months of 2015 , up $11 million compared to $74 million for the first nine months of 2014 . Segment revenue increased $9 million to $266 million for the first nine months of 2015 compared to $257 million for the first nine months of 2014 primarily due to growth in average loan balances, partially offset by lower spreads on loan products. The credit provision decreased $7 million to $30 million during the first nine months of 2015 due to improvement in the loan credit quality. Average loan balances were $9.4 billion for the first nine months of 2015 , up $441 million from the first nine months of 2014 . Average deposit balances were $5.7 billion for the first nine months of 2015 , up $602 million from the first nine months of 2014 . Average allocated capital increased $200 million to $967 million for the first nine months of 2015 reflecting the increase in the segment’s loan balances.

The Community, Consumer, and Business segment consists of lending and deposit solutions to individuals and small to mid-sized businesses and also provides a variety of investment and fiduciary products and services. The Community, Consumer, and Business segment had net income of $49 million for the first nine months of 2015 , up $27 million compared to $22 million in the first nine months of 2014 . Segment revenue increased $66 million to $462 million for the first nine months of 2015, primarily due to higher insurance commissions from the Ahmann & Martin Co. acquisition, higher mortgage banking income as well as changes in the long-term funding rates utilized in the funds transfer pricing methodology for allocating interest credits. The credit provision for loans increased to $20 million for the first nine months of 2015 due to loan growth, partially offset by improving credit quality. Total noninterest expense increased $20 million to $366 million for the first nine months of 2015 , primarily due to the Ahmann & Martin Co. acquisition. Average loan balances were $8.7 billion for the first nine months of 2015, up $1.1 billion from the first nine months of 2014 . Average deposits were $10.8 billion for the first nine months of 2015 , up $914 million from the first nine months of 2014 . Average allocated capital increased to $640 million for the first nine months of 2015 reflecting the increase in the segment's loan balances.

The Risk Management and Shared Services segment had net income of $11 million in the first nine months of 2015 , down $35 million compared to $46 million for the first nine months of 2014. The decrease was due to a $45 million decrease in net interest income related to changes in the long-term funding rates utilized in the funds transfer pricing methodology for allocating interest credits to the Corporate and Commercial Specialty and Community, Consumer, and Business segments. Average earning asset balances were $6.3 billion for the first nine months of 2015 , up $393 million from an average balance of $5.9 billion for the first

Table of Contents

nine months of 2014 , primarily in investment securities. Average deposits were $3.1 billion for the first nine months of 2015 , up $799 million from the first nine months of 2014 . Average allocated capital decreased to $214 million for the first nine months of 2015 .

Comparable Quarter Segment Review

The Corporate and Commercial Specialty segment had net income of $27 million for the third quarter of 2015 , up $1 million compared to $26 million for the comparable quarter in 2014. Segment revenue increased $5 million compared to the third quarter of 2014 primarily due to growth in average loan balances, partially offset by lower spreads on loan products. Total noninterest expense increased $2 million to $37 million for the third quarter of 2015 , primarily due to an increase in personnel expense. Average loan balances were $9.5 billion for the third quarter of 2015 , up $717 million from an average balance of $8.8 billion for the third quarter of 2014 . Average deposit balances were $6.0 billion for the third quarter of 2015 , up $952 million from the comparable quarter of 2014. Average allocated capital increased to $988 million for the third quarter of 2015 reflecting the increase in the segment’s loan balances.

The Community, Consumer, and Business Banking segment had net income of $16 million for the third quarter of 2015 compared to $5 million in the comparable quarter of 2014. Segment revenue increased $16 million to $153 million for the third quarter of 2015 primarily due to higher insurance commissions from the Ahmann & Martin Co. acquisition as well as changes in the long-term funding rates utilized in the funds transfer pricing methodology for allocating interest credits. The credit provision for loans decreased to $6 million for the third quarter of 2015 , due to improvement in the loan credit quality. Average loan balances were $8.9 billion for the third quarter of 2015 , up $607 million from the comparable quarter of 2014. Average deposits were $11.0 billion for the third quarter of 2015 , up $632 million from average deposits of $10.3 billion for the comparable quarter of 2014. Average allocated capital increased to $633 million for the third quarter of 2015 reflecting the increase in the segment's loan balances.

The Risk Management and Shared Services segment had net income of $6 million for the third quarter of 2015 , down $14 million compared to $20 million for the comparable quarter in 2014. The decrease was primarily due to a $14 million decrease in net interest income related to changes in the long-term funding rates utilized in the funds transfer pricing methodology for allocating interest credits to the Corporate and Commercial Specialty and Community, Consumer and Business segments. Average earning asset balances were $6.4 billion for the third quarter of 2015, up $417 million compared to the third quarter of 2014 , primarily in investment securities. Average deposits were $3.3 billion for the third quarter of 2015 , up $837 million versus the comparable quarter of 2014. Average allocated capital decreased to $216 million in the third quarter of 2015 .

Critical Accounting Policies

The consolidated financial statements of the Corporation are prepared in conformity with U.S. generally accepted accounting principles and follow general practices within the industries in which it operates. This preparation requires management to make estimates, assumptions, and judgments that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, actual results could differ from the estimates, assumptions, and judgments reflected in the financial statements. Certain policies inherently have a greater reliance on the use of estimates, assumptions, and judgments and, as such, have a greater possibility of producing results that could be materially different than originally reported. Management believes the following policies are both important to the portrayal of the Corporation’s financial condition and results of operations and require subjective or complex judgments and, therefore, management considers the following to be critical accounting policies. The critical accounting policies are discussed directly with the Audit Committee of the Corporation’s Board of Directors.

Allowance for Loan Losses

Management’s evaluation process used to determine the appropriateness of the allowance for loan losses is subject to the use of estimates, assumptions, and judgments. The evaluation process combines many factors: management’s ongoing review and grading of the loan portfolio, consideration of historical loan loss and delinquency experience, trends in past due and nonaccrual loans, risk characteristics of the various classifications of loans, concentrations of loans to specific borrowers or industries, existing economic conditions, the fair value of underlying collateral, and other qualitative and quantitative factors which could affect probable credit losses. Because current economic conditions can change and future events are inherently difficult to predict, the anticipated amount of estimated loan losses, and therefore the appropriateness of the allowance for loan losses, could change significantly. As an integral part of their examination process, various regulatory agencies also review the allowance for loan

Table of Contents

losses. Such agencies may require additions to the allowance for loan losses or may require that certain loan balances be charged off or downgraded into criticized loan categories when their credit evaluations differ from those of management, based on their judgments about information available to them at the time of their examination. The Corporation believes the level of the allowance for loan losses is appropriate as recorded in the consolidated financial statements. See also Note 7, “Loans, Allowance for Credit Losses, and Credit Quality,” of the notes to consolidated financial statements and section “Allowance for Credit Losses.”

Goodwill Impairment Assessment

Mortgage Servicing Rights Valuation

The fair value of the Corporation’s mortgage servicing rights asset is important to the presentation of the consolidated financial statements since the mortgage servicing rights are carried on the consolidated balance sheet at the lower of amortized cost or estimated fair value. Mortgage servicing rights do not trade in an active open market with readily observable prices. As such, similar to other participants in the mortgage banking business, the Corporation relies on an independent valuation from a third party which uses a discounted cash flow model to estimate the fair value of its mortgage servicing rights. The use of a discounted cash flow model involves judgment, particularly of estimated prepayment speeds of underlying mortgages serviced and the overall level of interest rates. Loan type and note interest rate are the predominant risk characteristics of the underlying loans used to stratify capitalized mortgage servicing rights for purposes of measuring impairment. The Corporation periodically reviews the assumptions underlying the valuation of mortgage servicing rights. While the Corporation believes that the values produced by the discounted cash flow model are indicative of the fair value of its mortgage servicing rights portfolio, these values can change significantly depending upon key factors, such as the then current interest rate environment, estimated prepayment speeds of the underlying mortgages serviced, and other economic conditions. The proceeds that might be received should the Corporation actually consider a sale of some or all of the mortgage servicing rights portfolio could differ from the amounts reported at any point in time.

To better understand the sensitivity of the impact of prepayment speeds and refinance rates on the value of the mortgage servicing rights asset at September 30, 2015 (holding all other factors unchanged), if refinance interest rates were to decrease 50 basis points (bp), the estimated value of the mortgage servicing rights asset would have been approximately $10 million (or 15% ) lower. Conversely, if refinance interest rates were to increase 50 bp, the estimated fair value of the mortgage servicing rights asset would have been approximately $8 million (or 12% ) higher. However, the Corporation’s potential recovery recognition due to valuation improvement is limited to the balance of the mortgage servicing rights valuation reserve, which was approximately $1 million at September 30, 2015 . The potential recovery recognition is constrained as the Corporation has elected to use the amortization method of accounting (rather than fair value measurement accounting). Under the amortization method, mortgage servicing rights are carried at the lower of the initial capitalized amount, net of accumulated amortization, or estimated fair value. Therefore, the mortgage servicing rights asset may only be marked up to the extent of the previously recognized valuation reserve. The Corporation believes the mortgage servicing rights asset is properly recorded in the consolidated financial statements. See Note 8, “Goodwill and Other Intangible Assets,” of the notes to consolidated financial statements and section “Noninterest Income.”

Income Taxes

The assessment of tax assets and liabilities involves the use of estimates, assumptions, interpretations, and judgment concerning certain accounting pronouncements and federal and state tax codes and regulations. There can be no assurance that future events, such as court decisions or positions of federal and state taxing authorities, will not differ from management’s current assessment, the impact of which could be significant to the consolidated results of operations and reported earnings. Quarterly assessments are performed to determine if valuation allowances are necessary against any portion of the Corporation’s deferred tax assets. Assessing the need for, or sufficiency of, a valuation allowance requires management to evaluate all available evidence, both positive and negative, including the recent trend of quarterly earnings. Positive evidence necessary to overcome the negative evidence includes whether future taxable income in sufficient amounts and character within the carryback and carryforward periods is available under the tax law, including the use of tax planning strategies. When negative evidence (e.g., cumulative losses in recent years, history of operating loss or tax credit carryforwards expiring unused) exists, more positive evidence than negative evidence will be necessary. The Corporation has concluded that based on the level of positive evidence, it is more likely than not

Table of Contents

that the deferred tax asset will be realized. However, there is no guarantee that the tax benefits associated with the deferred tax assets will be fully realized. The Corporation believes the tax assets and liabilities are properly recorded in the consolidated financial statements. See also Note 10, “Income Taxes,” of the notes to consolidated financial statements and section “Income Taxes.”

Future Accounting Pronouncements

New accounting policies adopted by the Corporation are discussed in Note 3, “New Accounting Pronouncements Adopted,” of the notes to consolidated financial statements. The expected impact of accounting pronouncements recently issued or proposed but not yet required to be adopted are discussed below. To the extent the adoption of new accounting standards materially affects the Corporation’s financial condition, results of operations, or liquidity, the impacts are discussed in the applicable sections of this financial review and the notes to the consolidated financial statements.

In September 2015, the FASB issued an amendment to simplify the accounting for measurement adjustments to prior business combinations. The amendment requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The aquirer must record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendment also requires an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. This amendment is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The amendments should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this Update with earlier application permitted for financial statements that have not been issued. The Corporation intends to adopt the accounting standard during the first quarter of 2016, as required, and is currently evaluating the impact on its results of operations, financial position, and liquidity.

In April 2015, the FASB issued an amendment to provide guidance to customers about whether a cloud computing arrangement included a software license. If the cloud computing arrangement includes a software license, then the customer should account for the software license element consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. This amendment is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. Entities may apply the amendment prospectively or retrospectively to all prior periods presented in the financial statements. Early adoption is permitted. The Corporation intends to adopt the accounting standard during the first quarter of 2016, as required, and is currently evaluating the impact on its results of operations, financial position, and liquidity.

In April 2015, the FASB issued an amendment to simplify the presentation of debt issuance costs. The amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. In August 2015, the FASB expanded this amendment to include SEC staff views related to debt issuance costs associated with line-of-credit arrangements.The SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. This amendment is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Entities should apply the amendment retrospectively to all prior periods presented in the financial statements. Early adoption is permitted. The Corporation intends to adopt the accounting standard during the first quarter of 2016, as required, and is currently evaluating the impact on its results of operations, financial position, and liquidity.

In February 2015, the FASB issued an amendment to modify existing consolidation guidance for reporting companies that are required to evaluate whether they should consolidate legal entities. The new standard will place more emphasis on risk of loss when determining a controlling financial interest. Frequency in the application of related-party guidance for determining a controlling financial interest will be reduced. Also, consolidation conclusions for public and private companies among several industries that make use of limited partnerships or VIEs will be changed. This amendment is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Entities may apply the amendment using a modified retrospective approach or retrospectively to all prior periods presented in the financial statements. Early adoption is permitted, including adoption in an interim period. The Corporation intends to adopt the accounting standard during the first quarter of 2016, as required, and is currently evaluating the impact on its results of operations, financial position, and liquidity.

In January 2015, the FASB issued an amendment to eliminate from U.S. GAAP the concept of extraordinary items. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. If an event or transaction meets the criteria for extraordinary classification, an entity is required to segregate the extraordinary item from the results of ordinary operations and show the item separately in the income

statement, net of tax, after income from continuing operations. This amended guidance will prohibit separate disclosure of extraordinary items in the income statement. This amendment is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Entities may apply the amendment prospectively or retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Corporation intends to adopt the accounting standard during the first quarter of 2016, as required, with no material impact as no retrospective adjustments are anticipated.

In June 2014, the FASB issued an amendment to the stock compensation accounting guidance to clarify that a performance target that affects vesting of a share-based payment and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. This amendment is effective for annual reporting periods, including interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in this update either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The Corporation intends to adopt the accounting standard during the first quarter of 2016, as required, with no material impact on its results of operations, financial position, and liquidity.

In May 2014, the FASB issued an amendment to clarify the principles for recognizing revenue and to develop a common revenue standard. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” In applying the revenue model to contracts within its scope, an entity should apply the following steps: (1) Identify the contract(s) with a customer, (2) Identify the performance obligations in the contract, (3) Determine the transaction price, (4) Allocate the transaction price to the performance obligations in the contract, and (5) Recognize revenue when (or as) the entity satisfies a performance obligation. The standard applies to all contracts with customers except those that are within the scope of other topics in the FASB Codification. The standard also requires significantly expanded disclosures about revenue recognition. The amendment was originally effective for annual reporting periods beginning after December 15, 2016 (including interim reporting periods within those periods); however, in July 2015, the FASB approved a one year deferral of the effective date to December 15, 2017. Early application is not permitted. The Corporation intends to adopt the accounting standard during the first quarter of 2018, as required, and is currently evaluating the impact on its results of operations, financial position, and liquidity.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk

Information required by this item is set forth in Item 2 under the captions “Quantitative and Qualitative Disclosures about Market Risk” and “Interest Rate Risk.”

ITEM 4. Controls and Procedures

The Corporation maintains disclosure controls and procedures as required under Rule 13a-15 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Corporation’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

As of September 30, 2015 , the Corporation’s management carried out an evaluation, under the supervision and with the participation of the Corporation’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of its disclosure controls and procedures. Based on the foregoing, its Chief Executive Officer and Chief Financial Officer concluded that the Corporation’s disclosure controls and procedures were effective as of September 30, 2015 . No changes were made to the Corporation’s internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act of 1934) during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1. Legal Proceedings

A lawsuit, R.J. ZAYED v. Associated Bank, N.A., was filed in the United States District Court for the District of Minnesota on January 29, 2013. The lawsuit relates to a Ponzi scheme perpetrated by Oxford Global Partners and related entities (“Oxford”) and individuals and was brought by the receiver for Oxford. Oxford was a depository customer of the Bank. The lawsuit claims that the Bank is liable for failing to uncover the Oxford Ponzi scheme, and specifically alleges the Bank aided and abetted (1) the fraudulent scheme; (2) a breach of fiduciary duty; (3) conversion; and (4) false representations and omissions. The lawsuit seeks unspecified consequential and punitive damages. The District Court granted the Bank’s motion to dismiss the complaint on September 30, 2013. On March 2, 2015, the U.S. Court of Appeals for the Eighth Circuit reversed the District Court and remanded the case back to the District Court for further proceedings. It is not possible for management to assess the probability of a material adverse outcome or reasonably estimate the amount of any potential loss at this time. A lawsuit by investors in the same Ponzi scheme, Herman Grad, et al v. Associated Bank, N.A., brought in Brown County, Wisconsin in October 2009 was dismissed by the circuit court, and the dismissal was affirmed by the Wisconsin Court of Appeals in June 2011 in an unpublished opinion.
