Notes to Consolidated Financial Statements

(Unaudited)

Note 1. Basis of Presentation

TCF Financial Corporation (together with its direct and indirect subsidiaries, "we," "us," "our," "TCF" or the "Company"), a Delaware corporation, is a national bank holding company based in Wayzata, Minnesota. References herein to "TCF Financial" or the "Holding Company" refer to TCF Financial Corporation on an unconsolidated basis. TCF's principal subsidiary, TCF National Bank ("TCF Bank"), is headquartered in Sioux Falls, South Dakota.

The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore do not include all of the information and notes necessary for complete financial statements in conformity with U.S. generally accepted accounting principles ("GAAP"). The information in this Quarterly Report on Form 10-Q is written with the presumption that the users of the interim financial statements have read or have access to the Company's most recent Annual Report on Form 10-K, which contains the latest audited financial statements and notes thereto, together with Management's Discussion and Analysis of Financial Condition and Results of Operations at December 31, 2016, and for the year then ended. All significant intercompany accounts and transactions have been eliminated in consolidation. Accounting policies in effect at December 31, 2016 remain significantly unchanged and have been followed similarly as in previous periods.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. These estimates are based on information available to management at the time the estimates are made. Actual results could differ from those estimates. In the opinion of management, the accompanying unaudited consolidated financial statements contain all the significant adjustments, consisting of normal recurring items, considered necessary for fair presentation. The results of operations for interim periods are not necessarily indicative of the results to be expected for the entire year.

During the second quarter of 2017, the Company adopted Accounting Standards Update ("ASU") No. 2017-08: Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities, which clarifies the premium amortization period on purchased callable debt securities should be to the earliest call date, rather than the contractual maturity date. The adoption of this ASU was on a modified retrospective basis and required any adjustments as a result of the adoption during an interim period to be reflected as of January 1, 2017. The adoption of this ASU did not impact results of operations, retained earnings or cash flows.

Effective January 1, 2017, the Company adopted ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which simplified several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. As a result of the adoption, the Company recorded a cumulative effect reduction to the opening balance of retained earnings of $1.3 million and a corresponding increase to additional paid-in capital. This cumulative effect adjustment to retained earnings was related to a policy election to account for forfeitures as they occur, thereby eliminating the need for an estimated forfeiture reserve against future cancellations. The adoption of this ASU on a prospective basis requires that tax benefits related to stock compensation be recorded to income tax expense, instead of to additional paid-in capital. The Company elected the prospective basis regarding the presentation of stock compensation tax (expense) benefit in the Consolidated Statement of Cash Flows as an operating activity, and as a result prior periods were not adjusted.

Note 2.  Cash and Due from Banks

At September 30, 2017 and December 31, 2016, TCF Bank was required by Federal Reserve regulations to maintain reserves of $108.2 million and $103.7 million, respectively, in cash on hand or at the Federal Reserve Bank.

TCF maintains cash balances that are restricted as to their use in accordance with certain contractual agreements primarily related to the servicing of auto finance loans. Cash payments received on loans serviced for third parties are generally held in separate accounts until remitted. TCF may also retain cash balances for collateral on certain borrowings, forward foreign exchange contracts, interest rate contracts and other contracts. TCF maintained restricted cash totaling $38.8 million and $51.3 million at September 30, 2017 and December 31, 2016, respectively.

TCF had cash held in interest-bearing accounts of $429.0 million and $326.5 million at September 30, 2017 and December 31, 2016, respectively.

At September 30, 2017 and December 31, 2016, mortgage-backed securities with a carrying value of $1.1 million and $7.5 million, respectively, were pledged as collateral to secure certain deposits and borrowings. We have assessed each security with unrealized losses included in the table above for credit impairment. As part of that assessment we evaluated and concluded that we do not intend to sell any of the securities and that it is more likely than not that we will not be required to sell prior to recovery of the amortized cost. Unrealized losses on securities available for sale and securities held to maturity were due to changes in interest rates.

Gains (losses) on securities, net was $0.2 million for the third quarter and first nine months of 2017, compared with $(0.6) million and $(0.7) million for the same periods in 2016. There were no sales or impairment charges for securities available for sale during the third quarter and first nine months of 2017 and 2016. TCF received $0.2 millionin recoveries on previously impaired securities held to maturity for the third quarter and first nine months of 2017compared to impairment charges of $0.6 million and $0.7 million for the same periods in 2016.

Loan Sales The following tables summarize the net sales proceeds for consumer real estate and auto finance loans sold, the securitization receivable recorded, the interest-only strips received, the recorded investment in loans sold, including accrued interest, and the net gains, as applicable. TCF generally retains servicing on loans sold. Included in consumer real estate loans sold in the third quarter and first nine months of 2017 were $21.8 million and $71.2 million, respectively, of non-accrual loans, which were sold servicing released. The auto finance securitizations included in the third quarter and first nine months of 2016 qualify for sale accounting and are executed by transferring the recorded investment to trusts. These trusts are considered variable interest entities due to their limited capitalization and special purpose nature. TCF has concluded it is not the primary beneficiary of the trusts and therefore, they are not consolidated. No servicing assets or liabilities related to consumer real estate or auto finance loans were recorded within TCF's Consolidated Statements of Financial Condition, as the contractual servicing fees are adequate to compensate TCF for its servicing responsibilities based on the amount demanded by the marketplace.

TCF recorded no impairment charges on the consumer real estate interest-only strips in the third quarter and $0.9 million of impairment charges for the first nine months of 2017, respectively, compared with $0.2 million and $0.8 million for the same periods in 2016. TCF recorded $0.2 million and $0.4 million of impairment charges on the auto finance interest-only strips for the third quarter and first nine months of 2017, respectively, compared with $2.3 million for each of the same periods in 2016.

TCF's agreements to sell auto and consumer real estate loans typically contain certain representations, warranties and covenants regarding the loans sold or securitized. These representations, warranties and covenants generally relate to, among other things, the ownership of the loan, the validity, priority and perfection of the lien securing the loan, accuracy of information supplied to the buyer or investor, the loan's compliance with the criteria set forth in the agreement, the manner in which the loans will be serviced, payment delinquency and compliance with applicable laws and regulations. These agreements generally require the repurchase of loans or indemnification in the event TCF breaches these representations, warranties or covenants and such breaches are not cured. In addition, some agreements contain a requirement to repurchase loans as a result of early payoffs by the borrower, early payment default of the borrower, or the failure to obtain valid title. During the first nine months of 2017 and 2016, losses related to repurchases pursuant to such representations, warranties and covenants were immaterial. The majority of such repurchases were of auto finance loans where TCF typically has contractual agreements with the automobile dealerships that originated the loans requiring the dealers to repurchase such contracts from TCF.

Acquired Loans and Leases TCF acquires loans and leases through business combinations and purchases of loan and lease portfolios. These loans and leases are recorded at fair value at acquisition and the fair value discount or premium is recognized as an adjustment to yield over the remaining life of each loan or lease. Loans are considered purchased credit impaired ("PCI") loans if it is probable at acquisition that all contractually required payments will not be collected. Upon acquisition, the acquired PCI loans are recorded at fair value without a corresponding allowance for loan losses as the non-accretable discount is adequate to absorb expected remaining credit losses. The excess of expected cash flows to be collected over the initial fair value of the acquired portfolios is referred to as the accretable yield and is accreted into interest income over the estimated life of the acquired portfolios using the effective yield method. The accretable yield is affected by changes in interest rate indices for variable-rate acquired portfolios, changes in prepayment assumptions and changes in the expected principal and interest payments over the estimated life of the loan. These acquired loans are classified as accruing and interest income continues to be recognized unless expected credit losses exceed the non-accretable discount.

TCF purchased loans and leases at fair value of $624.6 million and $631.5 million during the third quarter and first nine months of 2017, respectively, compared with $17.5 million for each of the same periods in 2016. Included in loans and leases acquired during the third quarter of 2017 were $14.0 million of leasing and equipment finance PCI loans that TCF acquired on September 29, 2017. On the acquisition date, the leasing and equipment finance PCI loans had contractually required payments receivable of $24.0 million, expected cash flows of $16.6 million and a fair value (initial carrying amount) of $14.0 million. The $7.4 million difference between the contractually required payments receivable and the expected cash flows represents the non-accretable difference. The $2.6 million difference between the expected cash flows and fair value represented the initial accretable yield.

Accruing and Non-accrual Loans and Leases  TCF's key credit quality indicator is the receivable's payment performance status, defined as accruing or non-accruing. Non-accrual loans and leases are those which management believes have a higher risk of loss. Delinquent balances are determined based on the contractual terms of the loan or lease. TCF's accruing and non-accrual loans and leases were as follows:

Loan Modifications for Borrowers with Financial Difficulties  Included within loans and leases in the previous accruing and non-accrual loans and leases table are certain loans that have been modified in order to maximize collection of loan balances. If, for economic or legal reasons related to the customer's financial difficulties, TCF grants a concession, the modified loan is classified as a troubled debt restructuring ("TDR") loan. All loans classified as TDR loans are considered to be impaired. For purposes of this disclosure, PCI loans have been excluded.

TDR loans were as follows:

Total	$	103,940	$	45,588	$	149,528	$	126,041	$	81,342	$	207,383

Unfunded commitments to consumer real estate and commercial loans classified as TDRs were $0.4 million at both September 30, 2017 and December 31, 2016. At September 30, 2017 and December 31, 2016, no additional funds were committed to leasing and equipment finance, inventory finance or auto finance loans classified as TDRs.

Unrecognized interest represents the difference between interest income recognized on accruing TDR loans and the contractual interest that would have been recorded under the original contractual terms. For the third quarter of 2017, unrecognized interest income for consumer real estate first mortgage lien accruing TDR loans and consumer real estate junior lien accruing TDR loans was $0.4 million and $0.1 million, respectively. The average yield for the same period on consumer real estate accruing TDR loans was 4.3%, which compares to the original contractual average rate of 6.8%. For the third quarter of 2016, unrecognized interest income for the consumer real estate first mortgage lien accruing TDR loans and consumer real estate junior lien accruing TDR loans was $0.5 million and $0.2 million, respectively. The average yield for the same period on consumer real estate accruing TDR loans was 4.3%, which compares to the original contractual average rate of 6.7%. The unrecognized interest income for the remaining classes of finance receivables was not material for the third quarters of 2017 and 2016.

For the first nine months of 2017, unrecognized interest income for consumer real estate first mortgage lien accruing TDR loans and consumer real estate junior lien accruing TDR loans was $1.4 million and $0.5 million, respectively. For the first nine months of 2016, unrecognized interest income for consumer real estate first mortgage lien accruing TDR loans and consumer real estate junior lien accruing TDR loans was $1.5 million and $0.5 million, respectively. The average yield for both the first nine months of 2017 and 2016 on consumer real estate accruing TDR loans was 4.2%, which compares to the original contractual average rate of 6.7%. The unrecognized interest income for the remaining classes of finance receivables was not material for the first nine months of 2017 and 2016.

TCF considers a loan to have defaulted when under the modified terms it becomes 90 or more days delinquent, has been transferred to non-accrual status, has been charged down or has been transferred to other real estate owned or repossessed and returned assets. The following table summarizes the TDR loans that defaulted during the third quarter and first nine months of 2017 and 2016, which were modified during the respective reporting period or within one year of the beginning of the respective reporting period. Included in commercial loans that defaulted during the nine months ended September 30, 2017 was one commercial loan that was transferred to non-accrual status during the first quarter of 2017.

(1) The loan balances presented are not materially different than the pre-modification loan balances as TCF's loan modifications generally do not forgive principal amounts.

Consumer real estate TDR loans are evaluated separately in TCF's allowance methodology. Impairment is generally based upon the present value of the expected future cash flows discounted at the loan's initial effective interest rate, unless the loans are collateral dependent, in which case loan impairment is based upon the fair value of the collateral less selling expenses. The allowance on accruing consumer real estate TDR loans was $17.6 million, or 19.4% of the outstanding balance, at September 30, 2017, and $19.3 million, or 19.6% of the outstanding balance, at December 31, 2016. In determining impairment for consumer real estate accruing TDR loans, TCF utilized remaining re-default rates ranging from 9% to 33% at September 30, 2017 and 10% to 33% at December 31, 2016, depending on lien position and actual experience. At September 30, 2017, 1.3% of accruing consumer real estate TDR loans were more than 60 days delinquent, compared with 1.5% at December 31, 2016.

Consumer real estate TDR loans generally remain on accruing status following modification if they are less than 90 days past due and payment in full under the modified terms of the loan is expected based on a current credit evaluation and historical payment performance. Of the non-accrual TDR balance at September 30, 2017, $22.0 million, or 65.1%, were loans discharged in Chapter 7 bankruptcy that were not reaffirmed by the borrower, of which 70.4% were current. Of the non-accrual TDR balance at December 31, 2016, $47.4 million, or 65.9%, were loans discharged in Chapter 7 bankruptcy that were not reaffirmed, of which 82.2% were current. All eligible loans are re-aged to current delinquency status upon modification.

Commercial TDR loans are individually evaluated for impairment based upon the present value of the expected future cash flows discounted at the loan's initial effective interest rate, unless the loans are collateral dependent, in which case impairment is based upon the fair value of collateral less estimated selling costs; however if payment or satisfaction of the loan is dependent on the operation, rather than the sale of the collateral, the impairment does not include selling costs. The allowance on accruing commercial TDR loans was less than $0.1 million, or less than 0.1% of the outstanding balance, at September 30, 2017, and $1.1 million, or 5.6% of the outstanding balance, at December 31, 2016. No accruing commercial TDR loans were 60 days or more delinquent at September 30, 2017 and December 31, 2016.

Impaired Loans  TCF considers impaired loans to include non-accrual commercial loans, non-accrual equipment finance loans and non-accrual inventory finance loans, as well as all TDR loans. For purposes of this disclosure, PCI loans have been excluded. Non-accrual impaired loans, including non-accrual TDR loans, are included in non-accrual loans and leases within the previous tables. Accruing TDR loans have been disclosed by delinquency status within the previous tables of accruing and non-accrual loans and leases. In the following table, the loan balance of impaired loans represents the amount recorded within loans and leases on the Consolidated Statements of Financial Condition, whereas the unpaid contractual balance represents the balances legally owed by the borrowers.

On June 16, 2017, TCF Bank acquired 100% of the outstanding shares of Equipment Financing & Leasing Corporation ("EFLC"). EFLC provides operating leases and direct financing leases of material handling equipment primarily to Fortune 500 customers. TCF Bank paid $9.0 million in cash upon closing, recorded a liability of $5.9 million to be paid within three years and assumed $64.2 million of EFLC's debt that was subsequently paid off. Assets acquired consisted of $46.4 million of operating lease equipment, $5.9 millionof direct financing leases, $21.3 million of amortizable intangible assets, $2.2 million related to goodwill and approximately $3.3 million of cash, other assets and other liabilities, net. All of the goodwill relates to the wholesale banking segment. The weighted-average amortization periods of the acquired program agreement, non-compete agreement and customer base intangibles were 15 years, five years and three years, respectively. The amortizable intangible assets are amortized on an expected benefit basis over their estimated useful lives.

Amortization expense for intangible assets was $0.8 million and $1.2 million for the third quarter and first nine months of 2017, respectively, compared with $0.4 million and $1.1 million for the same periods in 2016. There was no impairment of goodwill or the intangible assets during the third quarter and first nine months of 2017 and 2016. Amortization expense for intangible assets is estimated to be $0.8 million for the remainder of 2017, $2.7 million for 2018, $2.3 million for 2019, $2.0 million for 2020 and $2.0 million for 2021.

Depositary Shares Representing 7.50% Series A Non-Cumulative Perpetual Preferred Stock At September 30, 2017 and December 31, 2016, TCF had 6,900,000 depositary shares outstanding each representing a 1/1000^th ownership interest in a share of the 7.50% Series A non-cumulative perpetual preferred stock, par value $0.01 per share, with a liquidation preference of $25,000 per share (equivalent to $25 per depositary share) (the "Series A Preferred Stock"). On September 15, 2017, TCF provided notice of its intent to redeem all outstanding shares of its Series A Preferred Stock and the related depositary shares during the fourth quarter of 2017. As a result, TCF reclassified the outstanding liquidation preference amount of the Series A Preferred Stock totaling $172.5 million from preferred stock to accrued expenses and other liabilities on the Consolidated Statement of Financial Condition because upon the notification date, the Series A Preferred Stock became mandatorily redeemable. The liquidation preference amount equals the redemption price for all outstanding shares of the Series A Preferred Stock. Deferred stock issuance costs of $5.8 million originally recorded as a reduction to preferred stock upon the issuance of the Series A Preferred Stock were reclassified to retained earnings and resulted in a non-cash, one-time reduction to net income available to common stockholders utilized in the computation of earnings per common share and diluted earnings per common share for the third quarter and first nine months of 2017. Effective October 16, 2017, TCF redeemed all outstanding shares of its Series A Preferred Stock and the related depositary shares using the net proceeds from the offering of its Series C depositary shares and additional cash on hand. Dividends were payable on the Series A Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year at a per annum rate of 7.50%. TCF paid cash dividends to holders of the Series A Preferred Stock of $3.2 million and $9.7 million, respectively, for the third quarter and first nine months of 2017 and 2016. Dividends of $1.6 million on the Series A Preferred Stock were accrued for the period from September 1, 2017 through October 15, 2017.

6.45% Series B Non-Cumulative Perpetual Preferred Stock At September 30, 2017 and December 31, 2016, TCF had 4,000,000 shares outstanding of the 6.45% Series B non-cumulative perpetual preferred stock, par value $0.01 per share, with a liquidation preference of $25 per share (the "Series B Preferred Stock"). Dividends are payable on the Series B Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year at a per annum rate of 6.45%. TCF paid cash dividends to holders of the Series B Preferred Stock of $1.6 million and $4.8 million, respectively, for the third quarter and first nine months of 2017 and 2016. The Series B Preferred Stock may be redeemed at TCF's option in whole or in part on or after December 19, 2017.

Depositary Shares Representing 5.70% Series C Non-Cumulative Perpetual Preferred Stock On September 14, 2017, TCF completed the public offering of 7,000,000 depositary shares, each representing a 1/1000^th ownership interest in a share of the 5.70% Series C non-cumulative perpetual preferred stock, par value $0.01 per share, with a liquidation preference of $25,000 per share (equivalent to $25 per depositary share) (the "Series C Preferred Stock") for an aggregate public offering price of $175.0 million. Net proceeds of the offering to TCF, after deducting deferred stock issuance costs of $5.6 million, were $169.4 million. Dividends are payable on the Series C Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year, commencing on December 1, 2017, at a per annum rate of 5.70%. The Series C Preferred Stock may be redeemed at TCF's option in whole or in part on December 1, 2022 or on any dividend payment date thereafter.

Note 10.  Regulatory Capital Requirements

TCF and TCF Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possible additional discretionary, actions by the federal banking agencies that could have a material adverse effect on TCF. In general, TCF Bank may not declare or pay a dividend to TCF Financial in excess of 100% of its net retained earnings for the current year combined with its net retained earnings for the preceding two calendar years, which was $462.7 million at September 30, 2017, without prior approval of the Office of the Comptroller of the Currency ("OCC"). The OCC also has the authority to prohibit the payment of dividends by a national bank when it determines such payments would constitute an unsafe and unsound banking practice. TCF Bank's ability to make capital distributions in the future may require regulatory approval and may be restricted by its regulatory authorities. TCF Bank's ability to make any such distributions will also depend on its earnings and ability to meet minimum regulatory capital requirements in effect during future periods. In the future, these capital adequacy standards may be higher than existing minimum regulatory capital requirements.

Regulatory capital information for TCF and TCF Bank was as follows:

N.A. Not Applicable.

At September 30, 2017, there were 350,000 shares of performance-based restricted stock awards outstanding that will vest only if certain performance goals and service conditions are achieved. Failure to achieve the performance goals and service conditions will result in all or a portion of the shares being forfeited.

Unrecognized stock compensation expense for restricted stock awards was $22.6 million with a weighted-average remaining amortization period of 1.8 years at September 30, 2017.

22

At September 30, 2017, there were 360,988 performance-based restricted stock units granted under the Omnibus Incentive Plan that will vest only if certain performance goals are achieved. The number of restricted stock units granted was at target and the actual restricted stock units granted will depend on actual performance with a maximum total payout of 150% of target. Failure to achieve the performance goals will result in all or a portion of the restricted stock units being forfeited. None of the performance-based restricted stock units have vested. The remaining weighted-average performance period of the restricted stock units was 2.0 years at September 30, 2017.

Compensation expense for restricted stock awards and restricted stock units was $2.4 million and $6.5 million for the third quarter and first nine months of 2017, respectively, compared with $2.0 million and $6.8 million for the same periods in 2016.

The valuation assumptions for stock options granted in 2008 under the Incentive Stock Program have not changed significantly from December 31, 2016 andno stock options have subsequently been granted under the Incentive Stock Program. TCF also has the ability to grant stock options under the Omnibus Incentive Plan. As of September 30, 2017, no stock options had been granted under the Omnibus Incentive Plan.

Note 12.  Employee Benefit Plans

TCF executes all of its forward foreign exchange contracts in the over-the-counter market with large financial institutions pursuant to International Swaps and Derivatives Association, Inc. agreements. These agreements include credit risk-related features that enhance the creditworthiness of these instruments as compared with other obligations of the respective counterparty with whom TCF has transacted by requiring that additional collateral be posted under certain circumstances. The amount of collateral required depends on the contract and is determined daily based on market and currency exchange rate conditions.

At September 30, 2017, credit risk-related contingent features existed on forward foreign exchange contracts with a notional value of $56.1 million. In the event TCF is rated less than BB- by Standard and Poor's, the contracts could be terminated or TCF may be required to provide approximately $1.1 million in additional collateral. There were no forward foreign exchange contracts containing credit risk-related features in a net liability position at September 30, 2017.

At September 30, 2017, TCF had posted $7.5 million and $1.4 million of cash collateral related to its interest rate contracts and other contracts, respectively, and received $7.0 million of cash collateral related to its forward foreign exchange contracts.

Note 14.  Fair Value Disclosures

TCF uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The Company's fair values are based on the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Securities available for sale, certain loans held for sale, interest-only strips, forward foreign exchange contracts, interest rate contracts, interest rate lock commitments, forward loan sales commitments, assets and liabilities held in trust for deferred compensation plans and other contracts are recorded at fair value on a recurring basis. From time to time we may be required to record at fair value other assets on a non-recurring basis, such as certain securities held to maturity, loans, other real estate owned, repossessed and returned assets and the securitization receivable. These non-recurring fair value adjustments typically involve application of lower of cost or fair value accounting or write-downs of individual assets.

25

TCF groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the degree and reliability of estimates and assumptions used to determine fair value as follows: Level 1, which includes valuations that are based on prices obtained from independent pricing sources for the same instruments traded in active markets; Level 2, which includes valuations that are based on prices obtained from independent pricing sources that are based on observable transactions of similar instruments, but not quoted markets; and Level 3, for which valuations are generated from Company model-based techniques that use significant unobservable inputs. Such unobservable inputs reflect estimates of assumptions that market participants would use in pricing the asset or liability.

The following is a discussion of the valuation methodologies used to record assets and liabilities at fair value on a recurring or non-recurring basis and for estimating fair value of financial instruments not recorded at fair value.

Investments The carrying value of investments in FHLB stock and Federal Reserve Bank stock, categorized as Level 2, approximates fair value based on redemption at par value.

Securities Held to Maturity Securities held to maturity consist primarily of securities of U.S. Government sponsored enterprises and federal agencies. The fair value of securities of U.S. Government sponsored enterprises and federal agencies, categorized as Level 2, is estimated using prices obtained from independent asset pricing services that are based on observable transactions, but not quoted markets. Management reviews the prices obtained from independent asset pricing services for unusual fluctuations and comparisons to current market trading activity. The fair value of other securities, categorized as Level 3, is estimated using probability of loss based on risk rating definitions. There is no observable secondary market for these securities.

Securities Available for Sale Securities available for sale consist primarily of securities of U.S. Government sponsored enterprises and federal agencies, and obligations of states and political subdivisions. The fair value of these securities, categorized as Level 2, is recorded using prices obtained from independent asset pricing services that are based on observable transactions, but not quoted markets. Management reviews the prices obtained from independent asset pricing services for unusual fluctuations and comparisons to current market trading activity.

Loans Held for Sale Loans held for sale are generally carried at the lower of cost or fair value. Estimated fair values are based on recent loan sale transactions and any available price quotes on loans with similar coupons, maturities and credit quality. Certain other loans held for sale are recorded at fair value under the elected fair value option. TCF relies on internal valuation models which utilize quoted investor prices to estimate the fair value of these loans. Loans held for sale are categorized as Level 3.

Loans The fair value of loans, categorized as Level 3, is estimated based on discounted expected cash flows and recent sales of similar loans. The discounted cash flows include assumptions for prepayment estimates over each loan's remaining life, consideration of the current interest rate environment compared with the weighted-average rate of each portfolio, a credit risk component based on the historical and expected performance of each portfolio and a liquidity adjustment related to the current market environment. TCF also uses pricing data from recent sales of loans with similar risk characteristics as data points to validate the assumptions used in estimating the fair value of certain loans.

Loans for which repayment is expected to be provided solely by the value of the underlying collateral, categorized as Level 3 and recorded at fair value on a non-recurring basis, are valued based on the fair value of that collateral less estimated selling costs. Such loans include non-accrual impaired loans as well as certain delinquent non-accrual consumer real estate and auto finance loans. The fair value of the collateral is determined based on internal estimates and assessments provided by third-party appraisers.

Interest-only Strips The fair value of interest-only strips, categorized as Level 3, represents the present value of future cash flows expected to be received by TCF on certain assets. TCF uses available market data, along with its own empirical data and discounted cash flow models, to arrive at the estimated fair value of its interest-only strips. The present value of the estimated expected future cash flows to be received is determined by using discount, loss and prepayment rates that TCF believes are commensurate with the risks associated with the cash flows and what a market participant would use. These assumptions are inherently subject to volatility and uncertainty and, as a result, the estimated fair value of the interest-only strips may fluctuate significantly from period to period.

26

Forward Foreign Exchange Contracts TCF's forward foreign exchange contracts are currency contracts executed in over-the-counter markets and are recorded at fair value using a cash flow model that includes key inputs such as foreign exchange rates and an assessment of the risk of counterparty non-performance. The risk of counterparty non-performance is based on external assessments of credit risk. The fair value of these contracts, categorized as Level 2, is based on observable transactions, but not quoted markets.

Interest Rate Contracts TCF executes interest rate swap agreements with commercial banking customers to facilitate the customer's risk management strategy. These interest rate swaps are simultaneously hedged by offsetting interest rate swaps TCF executes with a third party, minimizing TCF's net interest rate risk exposure resulting from such transactions. TCF also has an interest rate swap agreement to convert its $150.0 million of fixed-rate subordinated notes to floating rate debt. These derivative instruments are recorded at fair value. The fair value of these swap agreements, categorized as Level 2, is determined using a cash flow model which considers the forward curve, the discount curve and credit valuation adjustments related to counterparty and/or borrower non-performance risk.

Interest Rate Lock Commitments and Forward Loan Sales Commitments TCF's interest rate lock commitments are derivative instruments that are carried at fair value. The related forward loan sales commitments to sell the resulting loans held for sale are also recorded at fair value under the elected fair value option. TCF relies on internal valuation models to estimate the fair value of these instruments. The valuation models utilize estimated rates of successful loan closings and quoted investor prices. While these models use both Level 2 and 3 inputs, TCF has determined that the inputs significant in the valuation of these commitments fall within Level 3 and therefore they are categorized as Level 3.

Other Real Estate Owned and Repossessed and Returned Assets The fair value of other real estate owned, categorized as Level 3, is based on independent appraisals, real estate brokers' price opinions or automated valuation methods, less estimated selling costs. Certain properties require assumptions that are not observable in an active market in the determination of fair value. The fair value of repossessed and returned assets is based on available pricing guides, auction results or price opinions, less estimated selling costs. Assets acquired through foreclosure, repossession or returned to TCF are initially recorded at the lower of the loan or lease carrying amount or fair value less estimated selling costs at the time of transfer to other real estate owned or repossessed and returned assets. Other real estate owned at September 30, 2017 and December 31, 2016 was $26.4 million and $46.8 million, respectively. Repossessed and returned assets at September 30, 2017 and December 31, 2016 was $11.4 million and $10.0 million, respectively. Other real estate owned and repossessed and returned assets were written down $1.6 million and $5.0 million, which was included in foreclosed real estate and repossessed assets, net expense for the third quarter and first nine months of 2017, respectively, compared with $2.0 million and $7.0 million for the same periods in 2016.

Securitization Receivable TCF executed an auto finance loan securitization during the second quarter of 2016 with a related receivable representing a cash reserve account posted at the inception of the securitization. The fair value of the securitization receivable, categorized as Level 3, is estimated based on discounted cash flows using interest rates for borrowings of similar remaining maturities plus a spread based on management's judgment.

Assets and Liabilities Held in Trust for Deferred Compensation Plans Assets held in trust for deferred compensation plans include investments in publicly traded securities, excluding TCF common stock reported in treasury and other equity, and U.S. Treasury notes. The fair value of these assets, categorized as Level 1, is based on prices obtained from independent asset pricing services based on active markets. The fair value of the liabilities equals the fair value of the assets.

Other Contracts TCF has a swap agreement related to the sale of TCF's Visa Class B stock, categorized as Level 3. The fair value of the swap agreement is based on TCF's estimated exposure related to the Visa covered litigation through a probability analysis of the funding and estimated settlement amounts.

Deposits The fair value of checking, savings and money market deposits, categorized as Level 1, is deemed equal to the amount payable on demand. The fair value of certificates of deposit, categorized as Level 2, is estimated based on discounted cash flows using currently offered market rates. The intangible value of long-term relationships with depositors is not taken into account in the fair values disclosed.

27

Long-term Borrowings The fair value of TCF's long-term borrowings, categorized as Level 2, is estimated based on observable market prices and discounted cash flows using interest rates for borrowings of similar remaining maturities and characteristics. The fair value of other long-term borrowings, categorized as Level 3, is based on unobservable inputs determined at the time of origination.

Financial Instruments with Off-Balance Sheet Risk The fair value of TCF's commitments to extend credit and standby letters of credit, categorized as Level 2, is estimated using fees currently charged to enter into similar agreements. Substantially all commitments to extend credit and standby letters of credit have floating interest rates and do not expose TCF to interest rate risk; therefore fair value is approximately equal to carrying value.

For purposes of this table, the derivative assets and derivative liabilities are presented gross of this netting adjustment.

Management assesses the appropriate classification of financial assets and liabilities within the fair value hierarchy by monitoring the level of available observable market information. Changes in markets or economic conditions, as well as changes to Company valuation models, may require the transfer of financial instruments from one fair value level to another. Such transfers, if any, are recorded at the fair values as of the beginning of the quarter in which the transfer occurred. TCF had no transfers in the nine months ended September 30, 2017 and 2016.

Fair Value Option

TCF Bank originates first mortgage lien loans in its primary banking markets and sells the loans through a correspondent relationship. TCF elected the fair value option for these loans. This election facilitates the offsetting of changes in fair values of the loans held for sale and the derivative financial instruments used to economically hedge them. The difference between the aggregate fair value and aggregate unpaid principal balance of these loans held for sale was as follows:

(In thousands)	At September 30, 2017		At December 31, 2016
Fair value carrying amount	$	4,193	$	6,498
Aggregate unpaid principal amount	4,082		6,563
Fair value carrying amount less aggregate unpaid principal	$	111	$	(65	)

Differences between the fair value carrying amount and the aggregate unpaid principal balance include changes in fair value recorded at and subsequent to funding and gains and losses on the related loan commitment prior to funding. No loans recorded under the fair value option were delinquent or on non-accrual status at September 30, 2017 or December 31, 2016. The net gain from initial measurement of the correspondent lending loans held for sale, any subsequent changes in fair value while the loans are outstanding and any actual adjustment to the gains realized upon sales of the loans totaled $1.3 million and $3.5 million for the third quarter and first nine months of 2017, respectively, compared with $2.1 million and $5.9 million for the same periods in 2016, and are included in gains on sales of consumer real estate loans, net. This amount excludes the impact from the interest rate lock commitments and forward loan sales commitments which are also included in gains on sales of consumer real estate loans, net.

Disclosures About Fair Value of Financial Instruments

Management discloses the estimated fair value of financial instruments, both assets and liabilities on and off the balance sheet, for which it is practicable to estimate fair value. These fair value estimates were made at September 30, 2017 and December 31, 2016, based on relevant market information and information about the financial instruments. Fair value estimates are intended to represent the price at which an asset could be sold or a liability could be settled. However, given there is no active market or observable market transactions for many of the Company's financial instruments, the estimates of fair values are subjective in nature, involve uncertainties and include matters of significant judgment. Changes in assumptions could significantly affect the estimated values.

31

The carrying amounts and estimated fair values of the Company's financial instruments, excluding short-term financial assets and liabilities as their carrying amounts approximate fair value, and excluding financial instruments recorded at fair value on a recurring basis, were as follows. This information represents only a portion of TCF's balance sheet and not the estimated value of the Company as a whole. Non-financial instruments such as the intangible value of TCF's branches and core deposits, leasing operations, goodwill, premises and equipment and the future revenues from TCF's customers are not reflected in this disclosure. Therefore, this information is of limited use in assessing the value of TCF.

Note 17. Business Segments

The Company's reportable segments are Consumer Banking, Wholesale Banking and Enterprise Services. Consumer Banking is comprised of all of the Company's consumer-facing businesses and includes retail banking, consumer real estate and auto finance. Wholesale Banking is comprised of commercial real estate and business lending, leasing and equipment finance and inventory finance. Enterprise Services is comprised of (i) corporate treasury, which includes TCF's investment and borrowing portfolios and management of capital, debt and market risks; (ii) corporate functions, such as information technology, risk and credit management, bank operations, finance, investor relations, corporate development, legal and human resources, that provide services to the operating segments; (iii) the Holding Company; and (iv) eliminations.

TCF evaluates performance and allocates resources based on each reportable segment's net income or loss. The reportable business segments follow GAAP as described in Note 1, Basis of Presentation, in Item 8 of TCF's 2016 Annual Report on Form 10-K, except for the accounting for intercompany interest income and interest expense, which are eliminated in consolidation, and presenting net interest income on a fully tax-equivalent basis. TCF generally accounts for inter-segment sales and transfers at cost.

Certain information for each of TCF's reportable segments, including reconciliations of TCF's consolidated totals, was as follows:

Note 18.  Litigation Contingencies

From time to time TCF is a party to legal proceedings arising out of its lending, leasing and deposit operations, including foreclosure proceedings and other collection actions as part of its lending and leasing collections activities. TCF may also be subject to regulatory examinations and enforcement actions brought by federal regulators, including the Securities and Exchange Commission, the Federal Reserve, the OCC and the Consumer Financial Protection Bureau ("CFPB") and TCF's regulatory authorities may impose sanctions on TCF for failures related to regulatory compliance. From time to time borrowers and other customers, and employees and former employees have also brought actions against TCF, in some cases claiming substantial damages. TCF and other financial services companies are subject to the risk of class action litigation. Litigation is often unpredictable and the actual results of litigation cannot be determined and therefore the ultimate resolution of a matter and the possible range of loss associated with certain potential outcomes cannot be established. Except as discussed below, based on our current understanding of TCF's pending legal proceedings, management does not believe that judgments or settlements arising from pending or threatened legal matters, individually or in the aggregate, would have a material adverse effect on the consolidated financial position, operating results or cash flows of TCF.

36

On January 19, 2017, the CFPB filed a civil lawsuit against TCF Bank in the United States District Court for the District of Minnesota (the "Court"), captioned Consumer Financial Protection Bureau v. TCF National Bank, alleging violations of the Consumer Financial Protection Act ("CFPA") and Regulation E, §1005.17 in connection with TCF Bank's practices administering checking account overdraft program "opt-in" requirements from 2010 to early 2014. In its complaint, the CFPB seeks, among other relief, redress for consumers, injunctive relief and unspecified penalties. On September 8, 2017, the Court issued a ruling on the motion made by TCF Bank to dismiss the complaint of the CFPB. In its ruling, the Court granted TCF Bank's motion to dismiss the CFPB's Regulation E claims and also dismissed the CFPB's unfair, deceptive and abusive conduct claims under the CFPA for periods prior to July 21, 2011. The Court did not grant TCF Bank's motion to dismiss CFPA claims for periods on or after July 21, 2011. TCF Bank rejects the claims made by the CFPB in its complaint and intends to vigorously defend against the CFPB's allegations. TCF has not accrued any amounts with respect to this matter because (i) TCF does not believe a loss is probable, (ii) TCF believes the Company has meritorious defenses to the claims made and (iii) the damages sought are unspecified and uncertain. Therefore, TCF is currently unable to reasonably estimate a range of potential loss, if any, relating to this matter. There is no assurance that the ultimate resolution of this lawsuit will not have a material adverse effect on the consolidated financial position, operating results or cash flows of TCF.

(1)  Foreign investments are deemed to be permanent in nature and therefore TCF does not provide for taxes on foreign currency translation adjustments.

Reclassifications of net (gains) losses to net income for securities available for sale and interest-only strips were recorded in the Consolidated Statements of Income in interest income for those securities that were previously transferred to held to maturity and in other non-interest expense for interest-only strips. During 2014, TCF transferred $191.7 million of available for sale mortgage-backed securities to held to maturity. At September 30, 2017 and December 31, 2016, the unrealized holding loss on the transferred securities retained in accumulated other comprehensive income (loss) totaled $12.3 million and $13.0 million, respectively. These amounts are amortized over the remaining lives of the transferred securities. See Note 12, Employee Benefit Plans, for additional information regarding TCF's recognized postretirement prior service cost. The tax effect of these reclassifications was recorded in income tax expense in the Consolidated Statements of Income.

TCF FINANCIAL CORPORATION AND SUBSIDIARIES

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

Overview

TCF Financial Corporation (together with its direct and indirect subsidiaries, "we," "us," "our," "TCF" or the "Company"), a Delaware corporation, is a national bank holding company based in Wayzata, Minnesota. References herein to "TCF Financial" or the "Holding Company" refer to TCF Financial Corporation on an unconsolidated basis. Its principal subsidiary, TCF National Bank ("TCF Bank"), is headquartered in Sioux Falls, South Dakota. At September 30, 2017, TCF had 321 bank branches in Illinois, Minnesota, Michigan, Colorado, Wisconsin, Arizona and South Dakota (TCF's primary banking markets).

TCF's common stock trades on the New York Stock Exchange under the symbol "TCF".

TCF provides convenient financial services through multiple channels in its primary banking markets. TCF has developed products and services designed to meet the specific needs of the largest consumer segments in the market. The Company focuses on attracting and retaining customers through service and convenience, including select locations open seven days a week with extended hours and on most holidays, full-service supermarket branches, access to automated teller machine ("ATM") networks and digital banking channels. TCF's philosophy is to generate interest income, fees and other revenue growth through business lines that emphasize higher yielding assets and low interest cost deposits. TCF's growth strategies include organic growth in existing businesses, development of new products and services, new customer acquisition and acquisitions of portfolios or businesses. New products and services are designed to build on existing businesses and expand into complementary products and services through strategic initiatives. Funded generally through retail deposit generation, TCF continues to focus on profitable asset growth.

Net interest income, the difference between interest income earned on loans and leases, securities, investments and other interest-earning assets (interest income) and interest paid on deposits and borrowings (interest expense), represented 68.2% and 67.6% of TCF's total revenue for the third quarter and first nine months of 2017, respectively, compared with 63.9% and 64.5% for the same periods in 2016. Net interest income can change significantly from period to period based on interest rates, customer prepayment patterns, the volume and mix of interest-earning assets and the volume and mix of interest-bearing and non-interest bearing deposits and interest-bearing borrowings. TCF manages the risk of changes in interest rates on its net interest income through a management Asset & Liability Committee and through related interest rate risk monitoring and management policies. See "Part I, Item 3. Quantitative and Qualitative Disclosures about Market Risk" for further discussion.

Non-interest income is a significant source of revenue for TCF and an important component of TCF's results of operations. Providing a wide range of retail banking services is an integral component of TCF's business philosophy. Primary drivers of bank fees and service charges include the number of customers we attract, the customers' level of engagement and the frequency with which the customer uses our solutions. In addition, the leasing and equipment finance lending business generates non-interest income primarily from operating leases and sales-type leases.

As an effort to diversify TCF's non-interest income sources and manage credit concentration risk, TCF sells loans, primarily in consumer real estate, which result in gains on sales, as well as servicing fee income. Primary drivers of gains on sales include TCF's ability to originate loans held for sale, identify loan buyers and execute loan sales. TCF implemented changes to its auto finance business strategy in 2017, transitioning from a reliance on gains on sales of loans to an originate-to-hold model. Over time, this shift may decrease liquidity, capital and operational risk, increase credit risk and will impact net interest income, provision for credit losses, gains on sales of auto loans and servicing fee income, as auto finance loans with a higher risk-adjusted yield are retained on the balance sheet.

The following portions of this Management's Discussion and Analysis of Financial Condition and Results of Operations ("Management's Discussion and Analysis") focus in more detail on the results of operations for the third quarter and first nine months of 2017 and 2016, and on information about TCF's balance sheet, loan and lease portfolio, liquidity, funding resources, capital and other matters.

Results of Operations

Performance Summary TCF reported diluted earnings per common share of 29 cents and 86 cents for the third quarter and first nine months of 2017, respectively, compared with 31 cents and 88 cents for the same periods in 2016. The amount of deferred stock issuance costs originally recorded in preferred stock upon the issuance of the 7.50% Series A non-cumulative perpetual preferred stock (the "Series A Preferred Stock") was reclassified to retained earnings on September 15, 2017, the date the Company announced its intent to redeem the outstanding Series A Preferred Stock which resulted in a non-cash, one-time reduction to net income available to common stockholders of $5.8 million utilized in the computation of earnings per common share and diluted earnings per common share. In addition, dividends of $1.6 million on the Series A Preferred Stock were accrued through October 15, 2017. These two items lowered earnings per common share and diluted earnings per common share by 4 cents per share for the third quarter and first nine months of 2017. TCF reported net income of $60.5 million and $167.2 million for the third quarter and first nine months of 2017, respectively, compared with $56.3 million and $162.0 million for the same periods in 2016. Net income increased $4.2 million, or 7.5%, and $5.2 million, or 3.2%, from the third quarter and first nine months of 2016, respectively.

Return on average assets on a fully tax-equivalent basis was 1.15% and 1.07% for the third quarter and first nine months of 2017, respectively, compared with 1.12% and 1.07% for the same periods in 2016. Total average assets were $21.9 billion and $21.8 billion for the third quarter and first nine months of 2017, respectively, increases of $0.9 billion, or 4.3%, and $0.7 billion, or 3.5%, from the same periods in 2016. Return on average common equity was 8.44% and 8.69% for the third quarter and first nine months of 2017, respectively, compared with 9.59% and 9.39% for the same periods in 2016. The decreases in the return on average common equity ratios were primarily due to decreases in net income available to common stockholders. TCF reported net income available to common stockholders of $48.3 million and $145.3 million for the third quarter and first nine months of 2017, respectively, compared with $51.4 million and $147.5 million for the same periods in 2016. Net income available to common stockholders decreased $3.2 million, or 6.1%, and $2.2 million, or 1.5%, from the third quarter and first nine months of 2016, respectively, primarily due to the impact of our notice to redeem the Series A Preferred Stock. Total average common equity was $2.3 billion and $2.2 billion for the third quarter and first nine months of 2017, respectively, increases of $0.1 billion, or 6.7%, and $0.1 billion, or 6.4%, from the same periods in 2016.

Consolidated Income Statement Analysis

Net Interest Income  Net interest income represented 68.2% and 67.6% of TCF's total revenue for the third quarter and first nine months of 2017, respectively, compared with 63.9% and 64.5% for the same periods in 2016. Net interest income was $234.1 million and $683.4 million for the third quarter and first nine months of 2017, respectively, compared with $212.0 million and $636.7 million for the same periods in 2016. Net interest income increased $22.1 million, or 10.4%, and $46.7 million, or 7.3%, from the third quarter and first nine months of 2016, respectively. The average yield on interest-earning assets on a fully tax-equivalent basis was 5.07% and 4.96% for the third quarter and first nine months of 2017, respectively, compared with 4.76% and 4.78% for the same periods in 2016. Average interest-earning assets increased $782.3 million, or 4.0%, and $695.8 million, or 3.5%, from the third quarter and first nine months of 2016, respectively. The average rate on interest-bearing liabilities on a fully tax-equivalent basis was 0.62% and 0.57% for the third quarter and first nine months of 2017, respectively, compared with 0.56% for the same periods in 2016. Average interest-bearing liabilities increased $481.3 million, or 3.3%, and $357.5 million, or 2.4%, from the third quarter and first nine months of 2016, respectively.

The increase in net interest income from the third quarter of 2016was primarily due to an increase in interest income on loans and leases, partially offset by a decrease in interest income on loans held for sale and an increase in total interest expense. Total interest income was $257.6 million for the third quarter of 2017, compared with $232.7 million for the same period in 2016. Total interest income increased $24.9 million, or 10.7%, from the third quarter of 2016 primarily due to increased average yields and higher average balances of the variable- and adjustable-rate commercial loans and variable-rate inventory finance loans, as well as increased average yields on the variable- and adjustable-rate consumer real estate loans and fixed-rate auto finance loans. These increases were partially offset by a lower average balance in the fixed-rate consumer real estate portfolio. Total interest expense was $23.5 million for the third quarter of 2017, compared with $20.7 million for the same period in 2016. Total interest expense increased $2.8 million, or 13.5%, from the third quarter of 2016, primarily due to increased average rates and higher average balances of certificates of deposit, as well as higher average balances of long-term borrowings, partially offset by decreased average rates and lower average balances of money market accounts.

40

The increase in net interest income from the first nine months of 2016 was primarily due to an increase in interest income on loans and leases and an increase in interest income on securities available for sale, partially offset by a decrease in interest income on loans held for sale and an increase in interest expense on borrowings. Total interest income was $748.4 million for the first nine months of 2017, compared with $699.1 million for the same period in 2016. Total interest income increased $49.4 million, or 7.1%, from the first nine months of 2016 primarily due to higher average balances and increased average yields on the variable-rate inventory finance loans and increased average yields and higher average balances of the variable- and adjustable-rate commercial loans, as well as increased average yields on the fixed-rate auto finance loans and the variable- and adjustable-rate consumer real estate loans. The increase in interest income on securities available for sale was primarily due to a higher average balance. These increases were partially offset by a lower average balance in the fixed-rate consumer real estate portfolio. Interest expense on borrowings was $19.9 million for the first nine months of 2017, compared with $15.7 million for the same period in 2016. Interest expense on borrowings increased of $4.2 million, or 26.8%, from the first nine months of 2016, primarily due to higher average balances of Federal Home Loan Bank ("FHLB") advances.

Net interest income on a fully tax-equivalent basis divided by average interest-earning assets is referred to as the net interest margin, expressed as a percentage. Net interest income and net interest margin are affected by (i) changes in prevailing short- and long-term interest rates, (ii) loan and deposit pricing strategies and competitive conditions, (iii) the volume and mix of interest-earning assets, non-interest bearing deposits and interest-bearing liabilities, (iv) the level of non-accrual loans and leases and other real estate owned and (v) the impact of modified loans and leases.

Net interest margin was 4.61% and 4.53% for the third quarter and first nine months of 2017, respectively, compared with 4.34% and 4.35% for the same periods in 2016. Net interest margin increased27 basis points and 18 basis points from the third quarter and first nine months of 2016, respectively. The increases in net interest margin from both periods were primarily due to higher average yields on the variable- and adjustable-rate loans due to interest rate increases. The increase from the third quarter of 2016 was partially offset by higher average rates on certificates of deposit.

TCF's average balances, interest, and yields and rates on major categories of TCF's interest-earning assets and interest-bearing liabilities on a fully tax-equivalent basis were as follows:

Provision for Credit Losses  The provision for credit losses is calculated as part of the determination of the allowance for loan and lease losses, which is a critical accounting estimate. TCF's evaluation of incurred losses is based upon historical loss rates multiplied by the respective portfolio's loss emergence period. Factors utilized in the determination and allocation of the allowance for loan and lease losses and the related provision for credit losses include historical trends in loss rates, a portfolio's overall risk characteristics, changes in its character or size, risk rating migration, delinquencies, collateral values, economic outlook and prevailing economic conditions.

The composition of TCF's provision for credit losses was as follows:

TCF's provision for credit losses was $14.5 million and $46.2 million for the third quarter and first nine months of 2017, respectively, compared with $13.9 million and $46.0 million for the same periods in 2016. The provision for credit losses increased $0.7 million, or 4.7%, from the third quarter of 2016 and $0.2 million, or 0.4%, from the first nine months of 2016. The increase from the third quarter of 2016 was primarily due to increased reserve requirements related to recent hurricanes of $5.2 million based on an initial analysis of current exposure and historical portfolio performance following similar natural disasters, primarily related to the auto finance portfolio. The increase was also due to increased net charge-offs in the auto finance portfolio and increased reserve requirements unrelated to the recent hurricanes in the commercial portfolio. These increases were partially offset by the recovery of $4.6 million on previous charge-offs related to the non-accrual loans that were sold and lower reserve requirements in the consumer real estate portfolio. The increase from the first nine months of 2016 was primarily due to growth, increased net charge-offs and increased reserve requirements related to recent hurricanes in the auto finance portfolio and increased net charge-offs and growth in the commercial portfolio. These increases were partially offset by the recovery of $13.3 million on previous charge-offs related to the non-accrual loans that were sold and lower reserve requirements in the consumer real estate portfolio, as well as lower reserve requirements in the inventory finance portfolio.

Net loan and lease charge-offs for the third quarter and first nine months of 2017 were $8.2 million, or 0.18% (annualized), and $26.2 million, or 0.19% (annualized), of average loans and leases, respectively, compared with $11.5 million, or 0.26% (annualized), and $33.5 million, or 0.25% (annualized), for the same periods in 2016. Net loan and lease charge-offs decreased $3.3 million and $7.3 million from the third quarter and first nine months of 2016, respectively. The decrease in net loan and lease charge-offs from the third quarter of 2016 was primarily due to the recovery of $4.6 million on previous charge-offs related to the consumer real estate non-accrual loans that were sold, partially offset by increased net charge-offs in the auto finance portfolio. The decrease from the first nine months of 2016 was primarily due to the recovery of $13.3 million on previous charge-offs related to the consumer real estate non-accrual loans that were sold in the first and third quarters of 2017, partially offset by increased net charge-offs in the auto finance and commercial portfolios.

Non-interest Income  Non-interest income is a significant source of revenue for TCF, representing 31.8% and 32.4% of total revenue for the third quarter and first nine months of 2017, respectively, compared with 36.1% and 35.5% for the same periods in 2016, and is an important factor in TCF's results of operations. Non-interest income was $109.2 million and $327.4 million for the third quarter and first nine months of 2017, respectively, compared with $119.7 million and $350.2 million for the same periods in 2016. Non-interest income decreased $10.4 million, or 8.7%, and $22.8 million, or 6.5%, from the third quarter and first nine months of 2016, respectively, primarily due to decreases in gains on sales of auto loans, net and gains on sales of consumer real estate loans, net, partially offset by increases in leasing and equipment finance non-interest income. The decrease from the first nine months of 2016 was also due to a decrease in fees and service charges, partially offset by an increase in servicing fee income.

The components of non-interest income were as follows:

Fees and Service Charges  Fees and service charges totaled $34.6 million and $98.6 million for the third quarter and first nine months of 2017, respectively, compared with $35.1 million and $102.5 million for the same periods in 2016. Fees and service charges decreased $0.5 million, or 1.4%, and $3.9 million, or 3.8%, from the third quarter and first nine months of 2016, respectively, primarily due to lower overdraft fees due to ongoing consumer behavior changes, as well as higher average checking account balances per customer.

45

Gains on Sales of Auto Loans, Net  Net gains on sales of auto loans totaled $0.0 million and $3.2 million for the third quarter and first nine months of 2017, respectively, compared with $11.6 million and $33.7 million for the same periods in 2016. Gains on sales of auto loans, net decreased $11.6 million, or 100.0%, and $30.4 million, or 90.4%, from the third quarter and first nine months of 2016, respectively, primarily due to the strategic shift in auto finance. TCF did not sell any auto loans in the third quarter of 2017 and sold $298.6 million of auto loans during the first nine months of 2017, compared with $614.9 million and $1.6 billion for the same periods in 2016.

Gains on Sales of Consumer Real Estate Loans, Net  Net gains on sales of consumer real estate loans totaled $8.0 million and $25.9 million for the third quarter and first nine months of 2017, respectively, compared with $13.5 million and $33.8 million for the same periods in 2016. Gains on sales of consumer real estate loans, net decreased $5.5 million, or 40.5%, and $7.8 million, or 23.2%, from the third quarter and first nine months of 2016, respectively, primarily due to decreased volume of loans sold. TCF sold $291.0 million and $943.8 million of consumer real estate loans during the third quarter and first nine months of 2017, respectively, compared with $437.1 million and $1.1 billion for the same periods in 2016. Included in consumer real estate loans sold in the third quarter and first nine months of 2017 were $21.8 million and $71.2 million, respectively, of non-accrual loans.

Servicing Fee Income  Servicing fee income totaled $10.0 million and $32.3 million for the third quarter and first nine months of 2017, respectively, compared with $10.4 million and $28.8 million for the same periods in 2016. Average loans and leases serviced for others were $5.0 billion and $5.3 billion for the third quarter and first nine months of 2017, respectively, compared with $5.1 billion and $4.7 billion for the same periods in 2016. Servicing fee income decreased $0.4 million, or 4.1%, and increased $3.6 million, or 12.4%, from the third quarter and first nine months of 2016, respectively. The decrease in servicing fee income from the third quarter of 2016 was primarily due to run-off in the auto finance serviced for others portfolio, partially offset by the cumulative effect of the increase in the portfolio of consumer real estate loans sold with servicing retained by TCF. The increase in servicing fee income from the first nine months of 2016 was primarily due to the cumulative effect of the increases in the portfolios of auto finance and consumer real estate loans sold with servicing retained by TCF.

Leasing and Equipment Finance Leasing and equipment finance non-interest income totaled $34.1 million and $102.2 million for the third quarter and first nine months of 2017, respectively, compared with $28.3 million and $87.9 million for the same periods in 2016. Leasing and equipment finance non-interest income increased $5.8 million, or 20.5%, and $14.4 million, or 16.3%, from the third quarter and first nine months of 2016, respectively. The increase from the third quarter of 2016 was primarily due to an increase in operating lease revenue mainly driven by the acquisition of Equipment Financing & Leasing Corporation ("EFLC") in the second quarter of 2017, partially offset by a decrease in sales-type lease revenue due to customer-driven events. The increase from the first nine months of 2016 was primarily due to an increase in operating lease revenue mainly driven by the acquisition of EFLC and an increase in sales-type lease revenue due to customer-driven events.

Compensation and Employee Benefits Expense Compensation and employee benefits expense totaled $115.1 million and $355.5 million for the third quarter and first nine months of 2017, respectively, compared with $117.2 million and $359.7 million for the same periods in 2016. Compensation and employee benefits expense decreased $2.0 million, or 1.7%, and$4.2 million, or1.2%, from the third quarter and first nine months of 2016, respectively, primarily due to reduced headcount in auto finance, partially offset by higher enterprise services contract labor utilization.

Other Non-interest Expense Other non-interest expense totaled $61.4 million and $186.5 million for the third quarter and first nine months of 2017, respectively, compared with $59.4 million and $172.2 million for the same periods in 2016. Other non-interest expense increased $2.0 million, or 3.3%, and $14.3 million, or 8.3%, from the third quarter and first nine months of 2016, respectively. The increase in other non-interest expense from the third quarter of 2016 was primarily due to increased professional fees of $5.9 million related primarily to strategic investments in technology capabilities, partially offset by a $2.2 million decrease in impairment charges on interest-only strips and a $1.7 million decrease in loan and lease processing expense. The increase from the first nine months of 2016 was primarily due to increased professional fees of $13.1 million related primarily to strategic investments in technology capabilities, higher severance expense of $5.7 million related primarily to the auto finance business and a $3.5 million increase in outside processing costs, partially offset by $3.5 million of branch realignment expense incurred in the first nine months of 2016, a $2.3 million decrease in loan and lease processing expense and a $1.8 million decrease in impairment charges on interest-only strips. See Note 16, Other Non-interest Expense of Notes to Consolidated Financial Statements for additional information.

Operating Lease Depreciation Operating lease depreciation totaled $15.7 million and $39.4 million for the third quarter and first nine months of 2017, respectively, compared with $10.0 million and $29.5 million for the same periods in 2016. Operating lease depreciation increased $5.7 million, or 56.4%, and $10.0 million, or 33.8%, from the third quarter and first nine months of 2016, respectively, primarily due to increases in leasing and equipment finance operating lease revenue related to the acquisition of EFLC.

Foreclosed Real Estate and Repossessed Assets, Net Foreclosed real estate and repossessed assets expense, net totaled $3.8 million and $13.0 million for the third quarter and first nine months of 2017, respectively, compared with $4.2 million and $11.3 million for the same periods in 2016. Foreclosed real estate and repossessed assets expense, net remained consistent with the third quarter of 2016 and increased$1.7 million, or 15.2%, from the first nine months of 2016, respectively. The increase from the first nine months of 2016 was primarily due to higher repossessed assets expense primarily attributable to auto finance, partially offset by lower operating costs associated with maintaining fewer consumer properties.

Income Taxes  Income tax expense was 32.7% and 30.6% of income before income tax expense for the third quarter and first nine months of 2017, respectively, compared with 34.0% and 33.8% for the same periods in 2016. The lower effective income tax rate from the first nine months of 2016 was primarily due to a $3.4 million favorable state tax settlement in the second quarter of 2017 and $2.8 million of tax benefits related to stock compensation recorded in income tax expense that were previously recorded in additional paid-in capital. See Note 1, Basis of Presentation of Notes to Consolidated Financial Statements for additional information.

Reportable Segment Results

The Company's reportable segments are Consumer Banking, Wholesale Banking and Enterprise Services. See Note 17, Business Segments of Notes to Consolidated Financial Statements for information regarding net income (loss), assets and revenues for each of TCF's reportable segments.

Consumer Banking

Consumer Banking is comprised of all of the Company's consumer-facing businesses and includes retail banking, consumer real estate and auto finance. TCF's consumer banking strategy is primarily to generate deposits to use for funding high credit quality secured loans and leases. Loans are originated for investment and for sale. Deposits are generated from consumers and small businesses to provide a source of low cost funds, with a focus on building and maintaining quality customer relationships. The Consumer Banking reportable segment generates a significant portion of the Company's net interest income and non-interest income from fees and service charges, card revenue, ATM revenue, gains on sales of loans and servicing fee income and incurs a significant portion of the Company's non-interest expense.

Consumer Banking generated net income available to common stockholders of $26.7 million and $75.1 million for the third quarter and first nine months of 2017, respectively, compared with $34.5 million and $94.3 million for the same periods in 2016. Consumer Banking net income available to common stockholders decreased $7.8 million, or 22.5%, and $19.1 million, or 20.3%, from the third quarter and first nine months of 2016, respectively.

Consumer Banking net interest income totaled $145.4 million and $428.8 million for the third quarter and first nine months of 2017, respectively, compared with $140.9 million and $420.9 million for the same periods in 2016. Net interest income increased $4.5 million, or 3.2%, and $7.9 million, or 1.9%, from the third quarter and first nine months of 2016, respectively.

The increase in net interest income from the third quarter of 2016 was primarily due to an increase in interest income on loans and an increase in funds transfer pricing credits, partially offset by a decrease in interest income on loans held for sale and an increase in total interest expense. Total interest income was $209.3 million for the third quarter of 2017, compared with $200.0 million for the same period in 2016. Total interest income increased $9.3 million, or 4.6%, from the third quarter of 2016 primarily due to increased average yields on the variable- and adjustable-rate consumer real estate loans and fixed-rate auto finance loans and an increase in funds transfer pricing credits, partially offset by a lower average balance in the fixed-rate consumer real estate portfolio. Total interest expense was $64.0 million for the third quarter of 2017, compared with $59.2 million for the same period in 2016. Total interest expense increased $4.8 million, or 8.2%, from the third quarter of 2016 primarily due to higher funds transfer pricing charges and an increase in interest expense on borrowings.

48

The increase in net interest income from the first nine months of 2016 was also primarily due to an increase in interest income on loans and an increase in funds transfer pricing credits, partially offset by a decrease in interest income on loans held for sale and an increase in total interest expense. Total interest income was $609.3 million for the first nine months of 2017, compared with $598.7 million for the same period in 2016. Total interest income increased $10.6 million, or 1.8%, from the first nine months of 2016 primarily due to increased average yields on the fixed-rate auto finance loans, an increase in funds transfer pricing credits and increased average yields on the variable- and adjustable-rate consumer real estate loans, partially offset by a lower average balance in the fixed-rate consumer real estate portfolio. Total interest expense was $180.5 million for the first nine months of 2017, compared with $177.8 million for the same period in 2016.Total interest expense increased $2.7 million, or 1.5%, from the first nine months of 2016 primarily due to an increase in interest expense on borrowings and higher funds transfer pricing charges, partially offset by lower interest expense on deposits.

Consumer Banking provision for credit losses totaled $11.1 million and $33.2 million for the third quarter and first nine months of 2017, respectively, compared with $10.7 million and $36.3 million for the same periods in 2016. The provision for credit losses increased $0.4 million, or 3.8%, and decreased $3.1 million, or 8.5%, from the third quarter and first nine months of 2016, respectively. The increase in the provision for credit losses from the third quarter of 2016 was primarily due to increased reserve requirements related to recent hurricanes and increased net charge-offs in the auto finance portfolio, partially offset by the recovery of $4.6 million on previous charge-offs related to the non-accrual loans that were sold and lower reserve requirements in the consumer real estate portfolio. The decrease in the provision for credit losses from the first nine months of 2016 was primarily due to the recovery of $13.3 million on previous charge-offs related to the non-accrual loans that were sold and lower reserve requirements in the consumer real estate portfolio, partially offset by growth, increased net charge-offs and increased reserve requirements related to recent hurricanes in the auto finance portfolio.

Consumer Banking non-interest income totaled $70.9 million and $215.2 million for the third quarter and first nine months of 2017, respectively, compared with $89.4 million and $254.1 million for the same periods in 2016. Non-interest income decreased $18.4 million, or 20.6%, and $39.0 million, or 15.3%, from the third quarter and first nine months of 2016, respectively, primarily due to decreases in net gains on sales of auto loans, net gains on sales of consumer real estate loans, and fees and service charges. The decrease from the first nine months of 2016 was partially offset by an increase in servicing fee income.

Net gains on sales of auto loans totaled $0.0 million and $3.2 million for the third quarter and first nine months of 2017, respectively, compared with $11.6 million and $33.7 million for the same periods in 2016. Net gains on sales of auto loans decreased $11.6 million, or 100.0%, and $30.4 million, or 90.4%, from the third quarter and first nine months of 2016, respectively, due to the strategic shift in auto finance.

Net gains on sales of consumer real estate loans totaled $8.0 million and $25.9 million for the third quarter and first nine months of 2017, respectively, compared with $13.5 million and $33.8 million for the same periods in 2016. Net gains on sales of consumer real estate loans decreased $5.5 million, or 40.4%, and $7.8 million, or 23.2%, from the third quarter and first nine months of 2016, respectively, primarily due to decreased volume of loans sold.

Fees and service charges totaled $31.1 million and $90.8 million for the third quarter and first nine months of 2017, respectively, compared with $33.3 million and $97.3 million for the same periods in 2016. Fees and service charges decreased $2.1 million, or 6.4%, and $6.5 million, or 6.7%, from the third quarter and first nine months of 2016, respectively, primarily due to lower overdraft fees due to ongoing consumer behavior changes, as well as higher average checking account balances per customer.

Servicing fee income totaled $9.6 million and $31.4 million for the third quarter and first nine months of 2017, respectively, compared with $10.1 million and $27.5 million for the same periods in 2016. Average consumer real estate and auto finance loans serviced for others were $4.7 billion and $5.0 billion for the third quarter and first nine months of 2017, respectively, compared with $4.8 billion and $4.5 billion for the same periods in 2016. Servicing fee income decreased $0.4 million, or 4.4%, and increased $3.9 million, or 14.2%, from the third quarter and first nine months of 2017, respectively. The decrease in servicing fee income from the third quarter of 2016 was primarily due to run-off in the auto finance serviced for others portfolio, partially offset by the cumulative effect of the increase in the portfolio of consumer real estate loans sold with servicing retained by TCF. The increase in servicing fee income from the first nine months of 2016 was primarily due to the cumulative effect of the increases in the portfolios of auto finance loans and consumer real estate loans sold with servicing retained by TCF.

49

Consumer Banking non-interest expense totaled $164.1 million and $494.4 million for the third quarter and first nine months of 2017, respectively, compared with $165.7 million and $491.6 million for the same periods in 2016. Non-interest expense decreased $1.6 million, or 1.0%, and increased$2.8 million, or 0.6%, from the third quarter and first nine months of 2016, respectively. The decrease in non-interest expense from the third quarter of 2016 was primarily due to a decrease in compensation and employee benefits expense attributable to reduced headcount in auto finance and a decrease in other non-interest expense attributable to a decrease in impairment charges on interest-only strips and lower loan and lease processing expense, partially offset by higher occupancy and equipment expense and higher professional fees related to strategic investments in technology capabilities. The increase from the first nine months of 2016 was primarily due to increases in occupancy and equipment expense, allocation expense from Enterprise Services, severance expense, advertising and marketing expense, professional fees and foreclosed real estate and repossessed assets expense. These increases were partially offset by decreases in compensation and employee benefits expense attributable to reduced headcount in auto finance, $3.5 million of branch realignment expense incurred in the first nine months of 2016, lower loan and lease processing expense and a decrease in impairment charges on interest-only strips.

Wholesale Banking

Wholesale Banking is comprised of commercial real estate and business lending, leasing and equipment finance and inventory finance. TCF's wholesale banking strategy is primarily to originate high credit quality secured loans and leases for investment.

Wholesale Banking generated net income available to common stockholders of $33.9 million and $100.4 million for the third quarter and first nine months of 2017, respectively, compared with $31.8 million and $98.3 million for the same periods in 2016.

The increase in net interest income from the third quarter of 2016 was primarily due to an increase in interest income on loans and leases, partially offset by an increase in total interest expense. Total interest income was $139.3 million for the third quarter of 2017, compared with $119.6 million for the same period in 2016. Total interest income increased $19.7 million, or 16.5%, from the third quarter of 2016 primarily due to increased average yields and higher average balances of the variable- and adjustable-rate commercial loans and variable-rate inventory finance loans. Total interest expense was $50.3 million for the third quarter of 2017, compared with $33.9 million for the same period in 2016. Total interest expense increased $16.5 million, or 48.7%, from the third quarter of 2016 primarily due to higher funds transfer pricing charges and an increase in interest expense on borrowings.

The provision for credit losses increased $0.2 million, or 7.6%, and $3.3 million, or 33.6%, from the third quarter and first nine months of 2016, respectively. The increase from the third quarter of 2016 was primarily due to increased reserve requirements in the commercial portfolio. The increase from the first nine months of 2016 was primarily due to increased net charge-offs and growth in the commercial portfolio, partially offset by lower reserve requirements in the inventory finance portfolio.

50

Wholesale Banking non-interest income totaled $38.3 million and $111.9 million for the third quarter and first nine months of 2017, respectively, compared with $30.4 million and $94.8 million for the same periods in 2016. Non-interest income increased $7.9 million, or 25.9%, and $17.1 million, or 18.1%, from the third quarter and first nine months of 2016, respectively, primarily due to an increase in leasing and equipment finance non-interest income attributable to operating lease revenue mainly driven by the acquisition of EFLC in the second quarter of 2017.

Wholesale Banking non-interest expense totaled $70.2 million and $202.7 million for the third quarter and first nine months of 2017, respectively, compared with $61.4 million and $184.2 million for the same periods in 2016. Non-interest expense increased $8.8 million, or 14.3%, and $18.5 million, or 10.0%, from the third quarter and first nine months of 2016, respectively, primarily due to increases in operating lease depreciation and occupancy and equipment expense.

The Company's investment portfolio accounts for the earning assets within this segment. Borrowings may be used to offset reductions in deposits or to support lending activities. This segment also includes residual revenues and expenses representing the difference between actual amounts incurred by Enterprise Services and amounts allocated to the operating segments, including interest rate risk residuals such as funds transfer pricing mismatches.

Enterprise Services generated a net loss available to common stockholders of $12.4 million and $30.2 million for the third quarter and first nine months of 2017, respectively, compared with $14.9 million and $45.1 million for the same periods in 2016.

Net interest expense decreased $14.4 million, or 98.6%, and $32.0 million, or 75.9%, from the third quarter and first nine months of 2016, respectively, primarily driven by a decrease in funds transfer pricing mismatches and an increase in interest income attributable to higher average balances of securities available for sale, partially offset by higher interest expense on borrowings.

Enterprise Services non-interest expense totaled $0.8 million and $15.0 million for the third quarter and first nine months of 2017, respectively, compared with $1.8 million and $8.7 million for the same periods in 2016. Non-interest expense decreased $1.0 million, or 56.8%, and increased $6.3 million, or 72.7%, from the third quarter and first nine months of 2016, respectively. The decrease from the third quarter of 2016 was primarily due to a decrease in occupancy and equipment expense, partially offset by higher professional fees related to strategic investments in technology capabilities and higher compensation and employee benefits expense due to higher contract labor utilization.

Consumer Real Estate The consumer real estate portfolio is secured by mortgages on residential real estate and consisted of $2.0 billion of first mortgage lien loans and $3.0 billion of junior lien loans at September 30, 2017, with a decrease of $339.4 million, or 14.8%, in the first mortgage lien portfolio, and an increase of $185.9 million, or 6.7%, in the junior lien portfolio, from $2.3 billion and $2.8 billion, at December 31, 2016, respectively. The decrease in the consumer real estate first mortgage lien portfolio was due primarily to run-off and the non-accrual loan sales in the first and third quarters of 2017 totaling $71.2 million. Loans are originated for investment and for sale. TCF sold $291.0 million and $943.8 million of consumer real estate loans in the third quarter and first nine months of 2017, respectively, compared with $437.1 million and $1.1 billion for the same periods in 2016. Consumer real estate originations were $0.6 billion and $1.7 billion for the third quarter and first nine months of 2017, respectively, compared with $0.7 billion and $1.9 billion for the same periods in 2016. Consumer real estate originations decreased $119.7 million, or 16.5%, and $161.1 million, or 8.5%, from the third quarter and first nine months of 2016, respectively. At September 30, 2017 and December 31, 2016, 61.3% and 68.1%, respectively, of the consumer real estate portfolio were in TCF's primary banking markets. At September 30, 2017 and December 31, 2016, 63.2% and 58.0%, respectively, of the consumer real estate portfolio carried a variable- or adjustable-rate generally tied to the prime rate. At September 30, 2017 and December 31, 2016, 41.3% and 47.3%, respectively, of TCF's consumer real estate loans consisted of closed-end loans. TCF's closed-end consumer real estate loans require payments of principal and interest over a fixed term.

The average Fair Isaac Corporation ("FICO^®") credit score at loan origination for the consumer real estate portfolio was 739 and 735 at September 30, 2017 and December 31, 2016, respectively. As part of TCF's credit risk monitoring, TCF obtains updated FICO score information quarterly. The average updated FICO score for the consumer real estate portfolio was 737 and 733 at September 30, 2017 and December 31, 2016, respectively.

TCF's consumer real estate underwriting standards are intended to produce adequately secured loans to customers with good credit scores at the origination date. Beginning in 2008, TCF generally has not made new loans in excess of 90% loan-to-value at origination. TCF also has not originated consumer real estate loans with multiple payment options or loans with "teaser" interest rates. At September 30, 2017, 67.5% of the consumer real estate portfolio had been originated since January 1, 2009 with annualized net recoveries of 0.01%.

The consumer real estate junior lien portfolio was comprised of $2.8 billion of home equity lines of credit ("HELOCs") and $218.1 million of amortizing consumer real estate junior lien mortgage loans at September 30, 2017, compared with $2.5 billion and $272.9 million at December 31, 2016, respectively. At September 30, 2017 and December 31, 2016, $2.3 billion and $2.0 billion, respectively, of the consumer real estate junior lien HELOCs had a 10-year interest-only draw period and a 20-year amortization repayment period and all were within the 10-year interest-only draw period and will not convert to amortizing loans until 2021 or later. At September 30, 2017 and December 31, 2016, $423.9 million and $525.4 million, respectively, of the consumer real estate junior lien HELOCs were interest-only revolving draw loans with no defined amortization period and original draw periods of 5 to 40 years. As of September 30, 2017, 16.7% of these loans mature prior to 2021. Outstanding balances on consumer real estate lines of credit were 67.9% of total lines of credit at September 30, 2017, compared to 67.1% at December 31, 2016.

Commercial Real Estate and Business Lending The commercial portfolio consisted of $2.7 billion of commercial real estate loans and $778.0 million of commercial business loans at September 30, 2017, with increases of $77.5 million, or 2.9%, and $125.7 million, or 19.3%, respectively, from $2.6 billion and $652.3 million, respectively, at December 31, 2016. The increases in the commercial portfolio were primarily due to originations outpacing lower prepayments and pay-offs during the third quarter and first nine months of 2017. Total commercial originations were $530.3 million and $1.4 billion in the third quarter and first nine months of 2017, respectively, compared with $501.6 million and $1.4 billion for the same periods in 2016. Total commercial originations increased $28.7 million, or 5.7%, and $43.8 million, or 3.2%, from the third quarter and first nine months of 2016, respectively. At September 30, 2017 and December 31, 2016, 74.0% and 77.8%, respectively, of TCF's commercial real estate loans outstanding were secured by properties located in TCF's primary banking markets. With an emphasis on secured lending, essentially all of TCF's commercial loans were secured either by properties or other business assets at September 30, 2017 and December 31, 2016. At September 30, 2017 and December 31, 2016, variable- and adjustable-rate loans represented 71.7% and 69.0%, respectively, of total commercial loans outstanding.

Leasing and Equipment Finance The leasing and equipment finance portfolio consisted of $2.5 billion of leases and $2.3 billion of loans at September 30, 2017, with increases of $147.6 million, or 6.4%, and $247.0 million, or 12.2%, respectively, from $2.3 billion of leases and $2.0 billion of loans at December 31, 2016. The increase in the leasing and equipment finance portfolio was primarily due to a loan and lease portfolio purchase of $445.5 million on September 29, 2017. Leasing and equipment finance originations (excluding loan and lease purchases) were $437.5 million and $1.4 billion in the third quarter and first nine months of 2017, respectively, compared with $562.4 million and $1.5 billion for the same periods in 2016. Leasing and equipment finance originations include operating lease originations. Leasing and equipment finance originations decreased $124.9 million, or 22.2%, and $163.6 million, or 10.6%, from the third quarter and first nine months of 2016, respectively. The uninstalled backlog of approved transactions was $517.5 million and $453.6 million at September 30, 2017 and December 31, 2016, respectively.

Inventory Finance The inventory finance portfolio totaled $2.6 billion at September 30, 2017, an increase of $105.9 million, or 4.3%, from $2.5 billion at December 31, 2016. The increase was primarily due to increases in the power sports and lawn and garden segments. TCF's inventory finance customers included more than 10,800 active dealers at both September 30, 2017 and December 31, 2016. Inventory finance originations were $1.9 billion and $5.6 billion in the third quarter and first nine months of 2017, respectively, compared with $1.6 billion and $5.0 billion for the same periods in 2016. Inventory finance originations increased $293.8 million, or 18.8%, and $541.0 million, or 10.8%, from the third quarter and first nine months of 2016, respectively. Origination levels are impacted by the velocity of fundings and repayments with dealers.

Auto Finance The auto finance portfolio totaled $3.2 billion at September 30, 2017, an increase of $592.7 million, or 22.4%, from $2.6 billion at December 31, 2016. The increase was primarily due to the strategic shift from an originate-to-sell model to an originate-to-hold model resulting in the reclassification of approximately $345 million of loans from held for sale to held for investment during the second quarter of 2017. As a result of the shift, loans are primarily originated for investment. TCF did not sell any auto loans in the third quarter of 2017 and sold $298.6 million for the first nine months in 2017, compared with $614.9 million and $1.6 billion for the same periods in 2016. Auto finance originations were $488.5 million and $1.9 billion in the third quarter and first nine months of 2017, respectively, compared with $880.7 million and $2.7 billion for the same periods in 2016. Auto finance originations decreased $392.2 million, or 44.5%, and $823.6 million, or 30.5%, from the third quarter and first nine months of 2016, respectively, primarily due to the strategic shift in auto finance. The auto finance network included more than 6,600 and 11,400 active dealers at September 30, 2017 and December 31, 2016, respectively. The decrease in the number of active dealers was primarily due to the strategic shift in auto finance. The auto finance portfolio consisted of 20.4% new auto loans and 79.6% used auto loans at September 30, 2017, compared with 23.3% and 76.7%, respectively, at December 31, 2016. The average original FICO score for the auto finance held for investment portfolio was 716 and 733 at September 30, 2017 and December 31, 2016, respectively. The decrease in average original FICO score was primarily due to the implementation of the shift.

Credit Quality The following summarizes TCF's loan and lease portfolio based on the credit quality factors that TCF believes are the most important and should be considered to understand the overall condition of the portfolio.

Past Due Loans and Leases Over 60-day delinquent loans and leases by type, excluding non-accrual loans and leases, were as follows. Delinquent balances are determined based on the contractual terms of the loan or lease. See Note 5, Allowance for Loan and Lease Losses and Credit Quality Information of Notes to Consolidated Financial Statements for additional information.

Total TDR loans were $149.5 million at September 30, 2017, a decrease of $57.9 million, or 27.9%, from $207.4 million at December 31, 2016. Accruing TDR loans were $103.9 million at September 30, 2017, a decrease of $22.1 million, or 17.5%, from $126.0 million at December 31, 2016. The decrease in accruing TDRs was primarily due to a $15.6 milliondecrease in commercial accruing TDR loans primarily due to payoffs and the transfer of loans to non-accrual status during the first quarter of 2017. Non-accrual TDR loans were $45.6 million at September 30, 2017, a decrease of $35.8 million, or 44.0%, from $81.3 million at December 31, 2016. The decrease was primarily due to a $38.1 million decrease in consumer real estate non-accrual TDR loans driven by the non-accrual loan sales in the first and third quarters of 2017.

TCF modifies loans through reductions in interest rates, extension of payment dates, term extensions or term extensions with a reduction of contractual payments, but generally not through reductions of principal.

Loan modifications to borrowers who have not been granted concessions are not included in the table above. Loan modifications to troubled borrowers are not reported as TDR loans in the calendar years after modification if the loans were modified to an interest rate equal to or greater than the yields of new loan originations with comparable risk at the time of restructuring and if the loan is performing based on the restructured terms; however, these loans are still considered impaired and follow TCF's impaired loan reserve policies.

TCF typically reduces a consumer real estate customer's contractual payments by reducing the interest rate by an amount appropriate for the borrower's financial condition. Loans discharged in Chapter 7 bankruptcy where the borrower did not reaffirm the debt are reported as non-accrual TDR loans upon discharge as a result of the removal of the borrower's personal liability on the loan. These loans may return to accrual status when TCF expects full repayment of the remaining pre-discharged contractual principal and interest. At September 30, 2017, 72.8% of total consumer real estate TDR loans were accruing and TCF recognized more than 63% and 62% of the original contractual interest due on accruing consumer real estate TDR loans for the third quarter and first nine months of 2017, respectively, yielding 4.3% and 4.2%, respectively, by modifying the loans to qualified customers instead of foreclosing on the property. At September 30, 2017, collection of principal and interest under the modified terms was reasonably assured on all accruing consumer real estate TDR loans.

Commercial loans modified when on non-accrual status continue to be reported as non-accrual loans until there is sustained repayment performance for a reasonable period of at least six consecutive months. At September 30, 2017, 57.3% of total commercial TDR loans were accruing and TCF recognized more than 98% and 97% of the original contractual interest due on accruing commercial TDR loans in the third quarter and first nine months of 2017, respectively, yielding 5.1% and 5.3%, respectively. At September 30, 2017, collection of principal and interest under the modified terms was reasonably assured on all accruing commercial TDR loans.

See Note 5, Allowance for Loan and Lease Losses and Credit Quality Information of Notes to Consolidated Financial Statements for additional information regarding TCF's loan modifications.

Non-accrual loans and leases and other real estate owned as a percentage of total loans and leases and other real estate owned	0.77			1.28
Allowance for loan and lease losses as a percentage of non-accrual loans and leases	140.65			88.33

Non-accrual loans and leases were $119.6 million at September 30, 2017, a decrease of $61.8 million, or 34.1%, from $181.4 million at December 31, 2016. The decrease was primarily due to the consumer real estate non-accrual loan sales of $71.2 million in the first and third quarters of 2017, partially offset by an increase in leasing and equipment finance and commercial non-accrual loans and leases. Other real estate owned was $26.4 million at September 30, 2017, a decrease of $20.4 million, or 43.6%, from $46.8 million at December 31, 2016. The decrease was primarily due to the sales of consumer real estate properties outpacing additions. Consumer real estate loans in process of foreclosure were $22.4 million and $32.1 million at September 30, 2017 and December 31, 2016, respectively.

Loans and leases are generally placed on non-accrual status when the collection of interest or principal is 90 days or more past due unless, in the case of commercial loans, they are well secured and in process of collection. Delinquent consumer real estate junior lien loans are also placed on non-accrual status when there is evidence that the related third-party first lien mortgage may be 90 days or more past due, or foreclosure, charge-off or collection action has been initiated. TDR loans are placed on non-accrual status prior to the past due thresholds outlined above if repayment under the modified terms is not likely after performing a well-documented credit analysis. Loans on non-accrual status are generally reported as non-accrual loans until there is sustained repayment performance for six consecutive months, with the exception of loans not reaffirmed upon discharge under Chapter 7 bankruptcy, which remain on non-accrual status until a well-documented credit analysis indicates full repayment of the remaining pre-discharged contractual principal and interest is likely. For purposes of this disclosure, purchased credit impaired loans have been excluded. Most of TCF's non-accrual loans and past due loans are secured by real estate. Given the nature of these assets and the related mortgage foreclosure, property sale and, if applicable, mortgage insurance claims processes, it can take 18 months or longer for a loan to migrate from initial delinquency to final disposition. This resolution process generally takes much longer for loans secured by real estate than for unsecured loans or loans secured by other property primarily due to state real estate foreclosure laws.

Loan and Lease Credit Classifications TCF assesses the risk of its loan and lease portfolio utilizing numerous risk characteristics as outlined in the previous sections. Loan and lease credit classifications are an additional characteristic monitored in the overall credit risk process. Loan and lease credit classifications are derived from standard regulatory rating definitions, which include: non-classified (pass and special mention) and classified (substandard and doubtful). Classified loans and leases have well-defined weaknesses, but may never result in a loss.

Loans and leases by portfolio and regulatory classification were as follows:

	At September 30, 2017
	Non-classified				Classified				Total
(In thousands)	Pass		Special Mention		Substandard		Doubtful
Consumer real estate	$	4,816,833	$	24,276	$	89,703	$	—	$	4,930,812

Total loans and leases	$	17,166,966	$	265,094	$	411,767	$	—	$	17,843,827

Total classified loans and leases were $300.9 million and $411.8 million at September 30, 2017 and December 31, 2016, respectively. The decrease of $110.8 million, or 26.9%, from December 31, 2016 was primarily due to decreases in classified inventory finance and consumer real estate loans, partially offset by increases in classified commercial loans and classified leasing and equipment finance loans and leases. The decrease in classified inventory finance loans was due to enhancements made to the model used to determine the classifications of loans in the first quarter of 2017 that better align with the inherent risk in this portfolio. The decrease in classified consumer real estate loans was a result of the non-accrual loan sales in the first and third quarters of 2017.

Allowance for Loan and Lease Losses The determination of the allowance for loan and lease losses is a critical accounting estimate. TCF's evaluation of incurred losses is based upon historical loss rates multiplied by the respective portfolio's loss emergence period. Factors utilized in the determination of the amount of the allowance include historical trends in loss rates, a portfolio's overall risk characteristics, changes in its character or size, risk rating migration, delinquencies, collateral values, economic outlook and prevailing economic conditions. The various factors used in the methodologies are reviewed on a periodic basis.

The Company considers the allowance for loan and lease losses of $168.2 millionappropriate to cover losses incurred in the loan and lease portfolios at September 30, 2017. However, no assurance can be given that TCF will not, in any particular period, sustain loan and lease losses that are sizable in relation to the amount reserved or will not require significant changes in the balance of the allowance for loan and lease losses due to subsequent evaluations of the loan and lease portfolios, in light of factors then prevailing, including economic conditions, information obtained during TCF's ongoing credit review process or regulatory requirements. Among other factors, an economic slowdown, increasing levels of unemployment, a decline in collateral values and/or rising interest rates may have an adverse impact on the current adequacy of the allowance for loan and lease losses by increasing credit risk and the risk of potential loss.

59

The total allowance for loan and lease losses is generally available to absorb losses from any segment of the portfolio. The allocation of TCF's allowance for loan and lease losses disclosed in the following table is subject to change based on changes in the criteria used to evaluate the allowance and is not necessarily indicative of the trend of future losses in any particular portfolio.

In conjunction with Note 5, Allowance for Loan and Lease Losses and Credit Quality Information of Notes to Consolidated Financial Statements, detailed information regarding TCF's allowance for loan and lease losses was as follows:

Liquidity Management TCF manages its liquidity to ensure that the funding needs of depositors and borrowers are met both promptly and in a cost-effective manner. Asset liquidity arises from liquid assets that can be sold or pledged as collateral, amortization, prepayment or maturity of assets and from the ability of TCF to sell loans. Liability liquidity results from the ability of TCF to maintain a diverse set of funding sources to promptly meet funding requirements.

TCF Bank had $192.8 million and $256.6 million of net liquidity qualifying interest-bearing deposits at the Federal Reserve Bank at September 30, 2017 and December 31, 2016, respectively. Interest-bearing deposits held at the Federal Reserve Bank and unencumbered U.S. Government sponsored enterprises and federal agencies mortgage-backed securities were $1.1 billion and $1.2 billion at September 30, 2017 and December 31, 2016, respectively. In addition, TCF held unencumbered obligations of states and political subdivisions totaling $767.5 million and $612.5 million at September 30, 2017 and December 31, 2016, respectively.

Deposits are the primary source of TCF's funds for use in lending and for other general business purposes. In addition to deposits, TCF receives funds from loan and lease repayments, loan sales and borrowings. Lending activities, such as loan originations and purchases and equipment purchases for lease financing, are the primary uses of TCF's funds.

The primary source of funding for TCF Commercial Finance Canada, Inc. ("TCFCFC") is a line of credit with TCF Bank. TCFCFC also maintains a $20.0 million Canadian dollar-denominated line of credit facility with a counterparty, which is guaranteed by TCF Bank. TCFCFC had no borrowings outstanding at September 30, 2017 and $2.2 million (USD) outstanding under the line of credit with the counterparty at December 31, 2016.

Deposits  Deposits totaled $18.1 billion at September 30, 2017, an increase of $0.9 billion, or 5.0%, from $17.2 billion at December 31, 2016. The increase was due to growth in certificates of deposit, savings and checking balances, partially offset by a decrease in money market balances.

Non-interest bearing checking accounts represented 20.1% and 20.0% of total deposits at September 30, 2017 and December 31, 2016, respectively. TCF's weighted-average interest rate for deposits, including non-interest bearing deposits, was 0.35% and 0.36% at September 30, 2017 and December 31, 2016, respectively. The decrease was primarily due to decreased average interest rates on money market balances, partially offset by increased average interest rates on certificates of deposit.

Checking, savings and certain money market deposits are an important source of low cost or no cost funds for TCF. The average balance of these types of deposits was $10.8 billion for both the third quarter and first nine months of 2017, compared with $10.6 billion for each of the same periods in 2016. These deposits comprised approximately 61% and 62% of total average deposits for the third quarter and first nine months of 2017, respectively, compared withapproximately 62% of total average deposits for each of the same periods in 2016.

Certificates of deposit totaled $5.0 billion and $4.1 billion at September 30, 2017 and December 31, 2016, respectively. The maturities of certificates of deposit with denominations equal to or greater than $100,000 were as follows:

(In thousands)	Denominations $100 Thousand or Greater at September 30, 2017
Maturity:
Three months or less	$	575,239
Over three through six months	207,269
Over six through 12 months	732,145
Over 12 months	897,530
Total	$	2,412,183

Borrowings Borrowings totaled $1.4 billion and $1.1 billion at September 30, 2017 and December 31, 2016, respectively. Historically, TCF has borrowed primarily from the FHLB of Des Moines, institutional sources under repurchase agreements and other sources. TCF had $1.5 billion of additional borrowing capacity at the FHLB of Des Moines at September 30, 2017, as well as access to overnight federal funds purchased lines and the Federal Reserve Discount Window.

See Note 8, Long-term Borrowings of Notes to Consolidated Financial Statements for additional information regarding TCF's long-term borrowings.

Capital Management TCF is committed to managing capital to maintain protection for stockholders, depositors and creditors. TCF employs a variety of capital management tools to achieve its capital goals, including, but not limited to, dividends, public offerings of preferred and common stock, common stock repurchases, redemption of preferred stock and the issuance or redemption of subordinated debt and other capital instruments. TCF maintains a Capital Planning and Dividend Policy which applies to TCF Financial and incorporates TCF Bank's Capital Planning and Dividend Policy. These policies ensure that capital strategy actions, including the addition of new capital, if needed, common stock repurchases, redemption of preferred stock or the declaration of preferred stock, common stock and bank dividends are prudent, efficient and provide value to TCF's stockholders, while ensuring that past and prospective earnings retention is consistent with TCF's capital needs, asset quality and overall financial condition. TCF and TCF Bank manage their capital levels to exceed all regulatory capital requirements, which were achieved at September 30, 2017 and December 31, 2016. See Note 10, Regulatory Capital Requirements of Notes to Consolidated Financial Statements.

Equity  Total equity at September 30, 2017 was $2.6 billion, or 11.3% of total assets, compared with $2.4 billion, or 11.4% of total assets, at December 31, 2016.

Preferred Stock  At September 30, 2017, there were 6,900,000 depositary shares outstanding, each representing a 1/1,000^th ownership interest in a share of the 7.50% Series A non-cumulative perpetual preferred stock, par value $0.01 per share, with a liquidation preference of $25,000 per share (equivalent to $25 per depositary share) (the "Series A Preferred Stock"). On September 15, 2017, TCF provided notice of its intent to redeem all outstanding shares of the Series A Preferred Stock and the related depositary shares during the fourth quarter of 2017. As a result, TCF reclassified the outstanding liquidation preference amount of the Series A Preferred Stock totaling $172.5 million from preferred stock to accrued expenses and other liabilities on the Consolidated Statement of Financial Condition because upon the notification date, the Series A Preferred Stock became mandatorily redeemable. The liquidation preference amount equals the redemption price for all outstanding shares of the Series A Preferred Stock. Effective October 16, 2017, TCF redeemed all outstanding shares of the Series A Preferred Stock and the related depositary shares using the net proceeds from the offering of its Series C depositary shares and additional cash on hand. Dividends were payable on the Series A Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year at a per annum rate of 7.50%. In addition, dividends of $1.6 million were accrued for the period from September 1, 2017 through October 15, 2017.

At September 30, 2017, there were 4,000,000 shares outstanding of the 6.45% Series B non-cumulative perpetual preferred stock, par value $0.01 per share, with a liquidation preference of $25 per share (the "Series B Preferred Stock"). Dividends are payable on the Series B Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year at a per annum rate of 6.45%. The Series B Preferred Stock may be redeemed at TCF's option in whole or in part on or after December 19, 2017.

On September 14, 2017, TCF completed the public offering of 7,000,000 depositary shares, each representing a 1/1000^th ownership interest in a share of the 5.70% Series C non-cumulative perpetual preferred stock, par value $0.01 per share, with a liquidation preference of $25,000 per share (equivalent to $25 per depositary share) (the "Series C Preferred Stock") for an aggregate public offering price of $175.0 million. Net proceeds of the offering to TCF, after deducting deferred stock issuance costs of $5.6 million, were $169.4 million. Dividends are payable on the Series C Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year, commencing on December 1, 2017, at a per annum rate of 5.70%. The Series C Preferred Stock may be redeemed at TCF's option in whole or in part on December 1, 2022 or on any dividend payment date thereafter.

Common Stock At September 30, 2017, TCF had 5.4 million shares remaining in its stock repurchase program authorized by its Board of Directors, which has no expiration. Prior consultation with the Federal Reserve is required before TCF could repurchase any shares of its common stock.

Dividends to common stockholders on a per share basis totaled 7.5 cents for the third quarters of 2017 and 2016. TCF's common dividend payout ratio was 25.9% and 24.2% for the third quarters of 2017 and 2016, respectively. TCF Financial's primary funding sources for dividends are earnings and dividends received from TCF Bank.

Total common stockholders' equity at September 30, 2017 was $2.3 billion, or 10.04% of total assets, compared with $2.2 billion, or 10.09% of total assets, at December 31, 2016. Tangible common equity at September 30, 2017 was $2.1 billion, or 9.06% of total tangible assets, compared with $1.9 billion, or 9.13% of total tangible assets, at December 31, 2016. Tangible common equity and tangible assets are not financial measures recognized under generally accepted accounting principles in the United States ("GAAP") (i.e., non-GAAP). Tangible common equity represents total equity less non-controlling interest in subsidiaries, preferred stock, goodwill and other intangibles. Tangible assets represent total assets less goodwill and other intangibles. When evaluating capital adequacy and utilization, management considers financial measures such as tangible common equity to tangible assets. This non-GAAP financial measure is viewed by management as a useful indicator of capital levels available to withstand unexpected market or economic conditions and also provide investors, regulators and other users with information to be viewed in relation to other banking institutions.

62

Reconciliations of the non-GAAP financial measures of tangible common equity and tangible assets to the GAAP measures of total equity and total assets were as follows:

Recent Accounting Developments

In August 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-12: Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which expands hedge accounting for nonfinancial and financial risk components and amends measurement methodologies to more closely align hedge accounting with a company’s risk management activities. The ASU decreases the complexity of preparing and understanding hedge results through measurement and reporting of hedge ineffectiveness. In addition, disclosures have been enhanced and the presentation of hedged results changed to align the effects of the hedging instrument and the hedged item. The adoption of this ASU will be required on a modified retrospective basis beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2019. Early adoption is allowed, however if adopted in an interim period any adjustments should be reflected at the beginning of the first year that includes the interim period. The adoption of this guidance will not have a material impact on our consolidated financial statements.

In May 2017, the FASB issued ASU No. 2017-09: Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting, which provides guidance about which changes to the terms and conditions of a share-based payment award requires an entity to apply modification accounting in Topic 718. The adoption of this ASU will be required on a prospective basis to an award modified beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Early adoption is allowed. The adoption of this guidance will not have a material impact on our consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07: Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which will change how employers that sponsor defined benefit pension and/or other postretirement benefit plans present the net periodic benefit cost in the income statement. Under the new guidance, employers will present the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. Only the service cost component will be eligible for capitalization in assets. The other components of net periodic benefit cost will be presented separately from the line item that includes service cost and outside of any subtotal of operating income. In addition, disclosure of the line items used to present the other components of net periodic benefit cost is required if the components are not presented separately in the income statement. The adoption of this ASU will be required on either a full or modified retrospective basis beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Early adoption is allowed. The adoption of this guidance will not have a material impact on our consolidated financial statements.

63

In February 2017, the FASB issued ASU No. 2017-05: Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20), which provides guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with non-customers. The ASU also clarifies that Accounting Standards Codification ("ASC") 610-20 applies to the derecognition of nonfinancial assets and in substance nonfinancial assets unless other specific guidance applies or the sale is to a customer. The new guidance does not apply to the derecognition of businesses, nonprofit activities, financial assets, including equity method investments, or to revenue contracts with customers. The adoption of this ASU will be required on either a full or modified retrospective basis beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Early adoption is allowed. The adoption of this guidance will not have a material impact on our consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies the definition of a business with the objective of adding guidance to assist companies with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The ASU provides a more robust framework to use in determining when a set of assets and activities is a business. The adoption of this ASU will be required on a prospective basis beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Upon adoption, TCF will evaluate future transactions to determine if they should be accounted for as acquisitions (or disposals) of assets or businesses.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires entities to show changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. The adoption of this ASU will be required on a retrospective basis beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. The adoption of this guidance will not have a material impact on our consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain types of cash receipts and cash payments are presented in the statement of cash flows. The adoption of this ASU will be required on a retrospective basis beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Early adoption is allowed. The adoption of this guidance will not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial assets, including trade and other receivables, held to maturity debt securities, loans and purchased financial assets with credit deterioration. The adoption of this ASU will be required on a modified retrospective basis with a cumulative-effect adjustment required beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2020. Early adoption is allowed. Management is currently evaluating the potential impact of this guidance on our consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-04, Liabilities - Extinguishment of Liabilities (Subtopic 405-20): Recognition of Breakage for Certain Prepaid Stored-Value Products, which requires issuers of prepaid stored-value products redeemable for goods, services or cash at third-party merchants to derecognize liabilities related to those products for breakage. The adoption of this ASU will be required on a retrospective or modified retrospective basis beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Early adoption is allowed. The adoption of this guidance will not have a material impact on our consolidated financial statements.

64

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which, along with other amendments, requires lessees to recognize most leases on their balance sheet. Lessor accounting is largely unchanged. The ASU requires both quantitative and qualitative disclosure regarding key information about leasing arrangements from both lessees and lessors. In September 2017, the FASB issued ASU No. 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842): Amendments to SEC Paragraphs, which rescinds certain SEC Observer comments and staff announcements from the lease guidance and incorporates SEC staff announcements on the effect of a change in tax law on leverage leases from ASC 840 into ASC 842. The adoption of these ASUs will be required on a modified retrospective basis beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2019. Early adoption is allowed. Management has started to implement this ASU which has included an initial evaluation of TCF's leasing contracts and activities. Management is currently evaluating the impact of electing the practical expedients, which would allow for existing leases to be accounted for consistent with current guidance, with the exception of the balance sheet recognition for lessees. Management will continue to evaluate the impact of this guidance on our consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which requires revenue recognition 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 August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delays the effective date of the new revenue recognition requirements in ASU No. 2014-09 by one year. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies how an entity should identify the unit of accounting for the principal versus agent evaluation, and how it should apply the control principle to certain types of arrangements by explaining what a principal controls before the specified good or service is transferred to the customer. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which amends the guidance for identifying performance obligations and accounting for a license which grants the right to use intellectual property. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides narrow-scope improvements to transition, collectability, noncash consideration and the presentation of sales and other similar taxes. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which provides guidance that affects narrow aspects of the guidance issued in ASU No. 2014-09. In September 2017, the FASB issued ASU 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842): Amendments to SEC Paragraphs, which rescinds certain SEC Observer comments on accounting for management fees based on a formula that is codified in ASC 605. The adoption of these ASUs will be required using one of two retrospective application methods beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. TCF plans to apply the modified retrospective method with a cumulative-effect adjustment to opening retained earnings. Management is currently evaluating the potential impact of this guidance on our consolidated financial statements. In evaluating this standard, management has determined that the majority of revenue earned by the Company is from revenue streams not included in the scope of this standard and therefore management does not expect the new revenue recognition guidance to have a material impact on our consolidated financial statements. Management is also evaluating existing disclosures and the need to provide additional information as a result of adoption of these ASUs.

Legislative and Regulatory Developments

Federal and state legislation impose numerous legal and regulatory requirements on financial institutions. Future legislative or regulatory change, or changes in enforcement practices or court rulings, may have a dramatic and potentially adverse impact on TCF.

67

Item 3. Quantitative and Qualitative Disclosures About Market Risk

TCF's results of operations depend, to a large degree, on its net interest income and its ability to manage interest rate risk. Although TCF manages other risks in the normal course of business, such as credit risk, liquidity risk, foreign currency risk and operational risk, the Company considers interest rate risk to be one of its more significant market risks.

Interest Rate Risk

TCF's Asset & Liability Committee ("ALCO") and the Finance Committee of TCF Financial's Board of Directors have adopted interest rate risk policy limits which are incorporated into the Company's investment policy. Interest rate risk is defined as the exposure of net interest income and fair value of financial instruments (interest-earning assets, deposits and borrowings) to movements in interest rates. Since TCF does not hold a trading portfolio, the Company is not exposed to market risk from trading activities. As such, the major sources of the Company's interest rate risk are timing differences in the maturity and repricing characteristics of assets and liabilities, changes in the shape of the yield curve, changes in consumer behavior and changes in relationships between rate indices (basis risk). Management measures these risks and their impact in various ways, including through the use of simulation and valuation analyses. The interest rate scenarios may include gradual or rapid changes in interest rates, spread narrowing and widening, yield curve twists and changes in assumptions about consumer behavior in various interest rate scenarios. A mismatch between maturities, interest rate sensitivities and prepayment characteristics of assets and liabilities results in interest rate risk. TCF, like most financial institutions, has material interest rate risk exposure to changes in both short- and long-term interest rates, as well as variable interest rate indices (e.g., the prime rate or the London InterBank Offered Rate).

TCF's ALCO is responsible for reviewing the Company's interest rate sensitivity position and establishing policies to monitor and limit exposure to interest rate risk. ALCO manages TCF's interest rate risk based on interest rate expectations and other factors. The principal objective of TCF in managing its assets and liabilities is to provide maximum levels of net interest income and facilitate the funding needs of the Company, while maintaining acceptable levels of interest rate risk and liquidity risk.

ALCO primarily uses two interest rate risk tools with policy limits to evaluate TCF's interest rate risk: net interest income simulation and economic value of equity ("EVE") analysis. In addition, the interest rate gap is reviewed periodically to monitor asset and liability repricing over various time periods.

Management utilizes net interest income simulation models to estimate the near-term effects of changing interest rates on its net interest income. Net interest income simulation involves forecasting net interest income under a variety of scenarios, including the level of interest rates, the shape of the yield curve and the spreads between market interest rates. Management exercises its best judgment in making assumptions regarding events that management can influence, such as non-contractual deposit repricings and events outside management's control, including consumer behavior on loan and deposit activity and the effect that competition has on both loan and deposit pricing. These assumptions are subjective and, as a result, net interest income simulation results will differ from actual results due to the timing, magnitude and frequency of interest rate changes and changes in market conditions, consumer behavior and management strategies, among other factors. TCF performs various sensitivity analyses on assumptions of new loan spreads, prepayment rates, basis risk, deposit attrition and deposit repricing.

The following table presents changes in TCF's net interest income over a twelve month period if short- and long-term interest rates were to sustain an immediate increase of 100 basis points and 200 basis points. The impact of planned growth and new business activities is factored into the simulation model.

	Impact on Net Interest Income
(Dollars in millions)	September 30, 2017				December 31, 2016
Immediate Change in Interest Rates:
+200 basis points	$	88.8	9.1	%	$	97.2	10.9	%
+100 basis points	48.5		5.0		52.1		5.9

As of September 30, 2017, approximately 60% of TCF's loan and lease balances were expected to reprice, amortize or prepay in the next 12 months and approximately 61% of TCF's deposit balances were low cost or no cost deposits. TCF believes that the mix of assets repricing compared with low cost or no cost deposits positions TCF well for rising interest rates.

Management also uses EVE and interest rate gap analyses to measure risk in the balance sheet that might not be taken into account in the net interest income simulation analysis. Net interest income simulation highlights exposure over a relatively short time period, while EVE analysis incorporates all cash flows over the estimated remaining life of all balance sheet positions. The valuation of the balance sheet, at a point in time, is defined as the discounted present value of asset cash flows minus the discounted present value of liability cash flows. EVE analysis addresses only the current balance sheet and does not incorporate the growth assumptions that are used in the net interest income simulation model. As with the net interest income simulation model, EVE analysis is based on key assumptions about the timing and variability of balance sheet cash flows and does not take into account any potential responses by management to anticipated changes in interest rates.

Interest rate gap is primarily the difference between interest-earning assets and interest-bearing liabilities repricing within a given period and represents the net asset or liability sensitivity at a point in time. An interest rate gap measure could be significantly affected by external factors such as loan prepayments, early withdrawals of deposits, changes in the correlation of various interest-bearing instruments, competition, or a rise or decline in interest rates.

Item 4. Controls and Procedures

Disclosure Controls and Procedures The Company carried out an evaluation, under the supervision and with the participation of the Company's management, including the Company's Chief Executive Officer (Principal Executive Officer), Chief Financial Officer (Principal Financial Officer) and Chief Accounting Officer (Principal Accounting Officer), of the effectiveness of the design and operation of the Company's disclosure controls and procedures pursuant to Rules 13a-15 and 15d-15 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Based upon that evaluation, management concluded that the Company's disclosure controls and procedures were effective as of September 30, 2017.

Disclosure controls and procedures are designed to ensure that information required to be disclosed by TCF in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls are also designed with the objective of ensuring that such information is accumulated and communicated to the Company's management, including the Chief Executive Officer (Principal Executive Officer), Chief Financial Officer (Principal Financial Officer) and Chief Accounting Officer (Principal Accounting Officer), as appropriate, to allow for timely decisions regarding required disclosure. TCF's disclosure controls also include internal controls that are designed to provide reasonable assurance that transactions are properly authorized, assets are safeguarded against unauthorized or improper use and that transactions are properly recorded and reported.

Changes in Internal Control Over Financial Reporting  There were no changes to TCF's internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the quarter ended September 30, 2017, that materially affected, or are reasonably likely to materially affect, TCF's internal control over financial reporting.

Part II - Other Information

Item 1. Legal Proceedings

From time to time, TCF is a party to legal proceedings arising out of its lending, leasing and deposit operations, including foreclosure proceedings and other collection actions as part of its lending and leasing collections activities. TCF may also be subject to regulatory examinations and enforcement actions brought by federal regulators, including the Securities and Exchange Commission, the Federal Reserve, the Office of the Comptroller of the Currency ("OCC") and the Consumer Financial Protection Bureau ("CFPB") and TCF's regulatory authorities may impose sanctions on TCF for failures related to regulatory compliance. From time to time, borrowers and other customers, and employees and former employees, have also brought actions against TCF, in some cases claiming substantial damages. TCF and other financial services companies are subject to the risk of class action litigation. Litigation is often unpredictable and the actual results of litigation cannot be determined, and therefore the ultimate resolution of a matter and the possible range of loss associated with certain potential outcomes cannot be established. Except as discussed below, based on our current understanding of TCF's pending legal proceedings, management does not believe that judgments or settlements arising from pending or threatened legal matters, individually or in the aggregate, would have a material adverse effect on the consolidated financial position, operating results or cash flows of TCF.

On January 19, 2017, the CFPB filed a civil lawsuit against TCF Bank in the United States District Court for the District of Minnesota (the "Court"), captioned Consumer Financial Protection Bureau v. TCF National Bank, alleging violations of the Consumer Financial Protection Act ("CFPA") and Regulation E, §1005.17 in connection with TCF Bank's practices administering checking account overdraft program "opt-in" requirements from 2010 to early 2014. In its complaint, the CFPB seeks, among other relief, redress for consumers, injunctive relief and unspecified penalties. On September 8, 2017, the Court issued a ruling on the motion made by TCF Bank to dismiss the complaint of the CFPB. In its ruling, the Court granted TCF Bank's motion to dismiss the CFPB's Regulation E claims and also dismissed the CFPB's unfair, deceptive and abusive conduct claims under the CFPA for periods prior to July 21, 2011. The Court did not grant TCF Bank's motion to dismiss CFPA claims for periods on or after July 21, 2011. TCF Bank rejects the claims made by the CFPB in its complaint and intends to vigorously defend against the CFPB's allegations. However, the ultimate resolution of this lawsuit and any other proceeding, action or matter arising from the same or similar facts or practices is uncertain, and this lawsuit and any other such proceedings, actions or matters may result in costs, losses, fines, penalties, restitution, injunctive relief, changes to our business practices and regulatory scrutiny, enforcement or restrictions which, individually or in the aggregate, could have a material adverse effect on our reputation, results of operations, cash flows, financial position, ability to offer certain products and business and prospects generally.
