TCF FINANCIAL CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

(Unaudited)

Note 1.  Basis of Presentation

TCF Financial Corporation, a Delaware corporation (“we,” “us,” “our,” “TCF,” or the “Company”), is a national bank holding company based in Wayzata, Minnesota. Unless otherwise indicated, references herein to “TCF” include its direct and indirect subsidiaries. Its principal subsidiary, TCF National Bank (“TCF Bank”), is headquartered in South Dakota. References herein to “TCF Financial” refer to TCF Financial Corporation on an unconsolidated basis.

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 generally accepted accounting principles in the United States (“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, 2014, and for the year then ended. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior period financial statements to conform to the current period presentation. Accounting policies in effect at December 31, 2014 remain significantly unchanged and will be 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 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.

Note 2.  Cash and Due from Banks

At March 31, 2015 and December 31, 2014, TCF Bank was required by Federal Reserve regulations to maintain reserves of $95.0 million and $98.7 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 sale and servicing of auto loans and consumer real estate loans. Cash payments received on loans serviced for third parties are generally held in separate accounts until remitted. TCF also retains cash balances for collateral on certain borrowings, forward foreign exchange contracts and interest rate contracts. TCF maintained restricted cash totaling $91.9 million and $67.8 million at March 31, 2015 and December 31, 2014, respectively.

TCF had cash held in interest-bearing accounts of $628.6 million and $842.1 million at March 31, 2015 and December 31, 2014, respectively.

There were no sales of securities available for sale during the three months ended March 31, 2015. Gross realized gains of $0.4 million were recognized on sales of securities available for sale during the three months ended March 31, 2014. At March 31, 2015 and December 31, 2014, mortgage-backed securities with a carrying value of $8.0 million and $8.2 million, respectively, were pledged as collateral to secure certain deposits and borrowings. There were no impairment charges recognized on securities available for sale during both the three months ended March 31, 2015 and 2014. Unrealized losses on securities available for sale are due to changes in interest rates. TCF has the ability and intent to hold these investments until a recovery of fair value occurs.

There were no transfers from available for sale mortgage-backed securities to held to maturity during the three months ended March 31, 2015. During the three months ended March 31, 2014, TCF transferred $191.7 million of available for sale mortgage-backed securities to held to maturity, reflecting TCF’s intent and ability to hold these securities to maturity. At March 31, 2015 and December 31, 2014, the unrealized holding loss on the transferred securities retained in accumulated other comprehensive loss totaled $15.7 million and $16.0 million, respectively. These amounts are amortized over the remaining lives of the transferred securities. Other held to maturity securities consist primarily of non-trading mortgage-backed securities and other bonds which qualify for investment credit under the Community Reinvestment Act. During the three months ended March 31, 2015, TCF recorded an impairment charge of $0.1 million on held to maturity securities, which had a carrying value of $4.8 million. There were no impairment charges recognized on held to maturity securities during the three months ended March 31, 2014.

(1)  Loans and leases are reported at historical cost including net direct fees and costs associated with originating and acquiring loans and leases, lease residuals, unearned income and unamortized purchase premiums and discounts. The aggregate amount of these loan and lease adjustments was $48.6 million and $43.4 million at March 31, 2015 and December 31, 2014, respectively.

The consumer real estate junior lien portfolio was comprised of $2.2 billion of home equity lines of credit (“HELOCs”) and $404.9 million of amortizing junior lien mortgage loans at March 31, 2015, compared with $2.1 billion and $424.4 million at December 31, 2014, respectively. At March 31, 2015 and December 31, 2014, $1.4 billion and $1.3 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 March 31, 2015 and December 31, 2014, $778.2 million and $816.0 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 March 31, 2015, 18.2% of these loans mature prior to 2021.

During the three months ended March 31, 2015 and 2014, TCF sold $203.5 million and $261.7 million, respectively, of consumer auto loans with servicing retained, received cash of $210.5 million and $267.2 million, respectively, and recognized net gains of $6.7 million and $8.8 million, respectively. Related to these sales, TCF retained interest-only strips of $0 and $4.5 million for the three months ended March 31, 2015 and 2014, respectively. Total interest-only strips related to sales of auto loans totaled $41.1 million and $48.6 million at March 31, 2015 and December 31, 2014, respectively. TCF recorded impairment charges on these interest-only strips of $0.5 million and $1.2 million during the three months ended March 31, 2015 and 2014, respectively, primarily as a result of higher prepayments than originally assumed. Contractual recourse liabilities related to sales of auto loans totaled $0.4 million and $0.7 million at March 31, 2015 and December 31, 2014, respectively. No servicing assets or liabilities related to consumer auto 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’s managed auto loan portfolio, which includes portfolio loans, loans held for sale and loans sold and serviced for others, totaled $4.2 billion and $3.8 billion at March 31, 2015 and December 31, 2014, respectively.

During the three months ended March 31, 2015 and 2014, TCF sold $264.3 million and $347.4 million, respectively, of consumer real estate loans, received cash of $271.0 million and $353.0 million, respectively, and recognized net gains of $8.2 million and $11.7 million, respectively. Related to these sales, TCF retained interest-only strips of $2.7 million and $8.2 million for the three months ended March 31, 2015 and 2014, respectively. Total interest-only strips related to sales of consumer real estate loans totaled $21.4 million and $21.2 million at March 31, 2015 and December 31, 2014, respectively. TCF had no impairment charges on these interest-only strips for the three months ended March 31, 2015 and 2014. Contractual recourse liabilities related to sales of consumer real estate loans totaled $0.6 million at both March 31, 2015 and December 31, 2014. No servicing assets or liabilities related to consumer real estate 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’s managed consumer real estate loan portfolio, which includes portfolio loans, loans held for sale and loans sold and serviced for others, totaled $7.1 billion at both March 31, 2015 and December 31, 2014.

TCF’s agreements to sell auto and consumer real estate loans typically contain certain representations and warranties regarding the loans sold. These representations and warranties 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, the loan’s compliance with the criteria set forth in the agreement, payment delinquency and compliance with applicable laws and regulations. TCF may be required to repurchase loans in the event of an unremedied breach of these representations or warranties. During the three months ended March 31, 2015 and 2014, losses related to repurchases pursuant to such representations and warranties were immaterial. The majority of such repurchases were of consumer auto loans where TCF typically has contractual agreements with the automobile dealerships that originated the loans requiring the dealers to repurchase such contracts from TCF.

Loan Modifications for Borrowers with Financial Difficulties  Included within loans and leases in the previous tables 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. TDR loans consist primarily of consumer real estate and commercial loans.

Total TDR loans at March 31, 2015 and December 31, 2014 were $273.7 million and $298.5 million, respectively, of which $167.8 million and $193.8 million were accruing at March 31, 2015 and December 31, 2014, respectively. TCF held consumer real estate TDR loans of $198.7 million and $199.6 million at March 31, 2015 and December 31, 2014, respectively, of which $111.7 million and $111.9 million were accruing at March 31, 2015 and December 31, 2014, respectively. TCF also held $67.3 million and $91.6 million of commercial TDR loans at March 31, 2015 and December 31, 2014, respectively, of which $55.1 million and $80.4 million were accruing at March 31, 2015 and December 31, 2014, respectively. TDR loans for the remaining classes of finance receivables were not material at March 31, 2015 or December 31, 2014.

The amount of unfunded commitments to commercial and consumer real estate loans classified as TDRs was $3.8 million and $3.9 million at March 31, 2015 and December 31, 2014, respectively. At March 31, 2015 and December 31, 2014, no additional funds were committed to leasing and equipment finance, inventory finance or auto finance loans classified as TDRs.

When a loan is modified as a TDR, principal balances are generally not forgiven. Loan modifications to troubled borrowers are not reported as TDR loans in the calendar year after modification if the loans were modified at an interest rate equal to the yields of new loan originations with comparable risk and the loans are performing based on the terms of the restructured agreements. All loans classified as TDR loans are considered to be impaired. During the three months ended March 31, 2015 and 2014, $9.0 million and $11.1 million, respectively, of commercial loans were removed from TDR status as they were restructured at market terms and are performing.

The financial effects of TDR loans represent the difference between interest income recognized on accruing TDR loans and the contractual interest that would have been recorded under the original contractual terms, or foregone interest income. For the three months ended March 31, 2015, foregone interest income for 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 3.9%, which compares to the original contractual average rate of 6.5%. For the three months ended March 31, 2014, foregone interest income for consumer real estate first mortgage lien accruing TDR loans and consumer real estate junior lien accruing TDR loans was $4.4 million and $0.3 million, respectively. The average yield for the same period on consumer real estate accruing TDR loans was 3.2%, which compares to the original contractual average rate of 6.7%. The foregone interest income for the remaining classes of finance receivables was not material for the three months ended March 31, 2015 and 2014.

The table below summarizes TDR loans that defaulted during the three months ended March 31, 2015 and 2014, which were modified during the respective reporting period or within one year of the beginning of the respective reporting period. TCF considers a loan to have defaulted when it becomes 90 or more days delinquent under the modified terms, has been transferred to non-accrual status subsequent to the modification or has been transferred to other real estate owned or repossessed and returned assets.

(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 or the fair value of the collateral less selling expenses for collateral dependent loans. The allowance on accruing consumer real estate TDR loans was $20.3 million, or 18.2% of the outstanding balance, at March 31, 2015, and $20.4 million, or 18.2% of the outstanding balance, at December 31, 2014. In determining impairment for consumer real estate accruing TDR loans, TCF utilized assumed remaining re-default rates ranging from 6% to 20% in 2015 and 4% to 22% in 2014, depending on modification type and actual experience. At March 31, 2015, 2.3% of accruing consumer real estate TDR loans were more than 60 days delinquent, compared with 2.4% at December 31, 2014.

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 March 31, 2015, $52.4 million, or 60.2%, were loans discharged in Chapter 7 bankruptcy that were not reaffirmed, of which 71.1% were current. Of the non-accrual TDR balance at December 31, 2014, $50.0 million, or 57.0%, were loans discharged in Chapter 7 bankruptcy that were not reaffirmed, of which 68.4% were current. All eligible loans are re-aged to current delinquency status upon modification.

15

Commercial TDR loans are individually evaluated for impairment based upon the present value of the expected future cash flows, or for collateral dependent loans, at the fair value of collateral less selling expense. The allowance on accruing commercial TDR loans was $1.1 million, or 2.1% of the outstanding balance, at March 31, 2015, and $1.4 million, or 1.7% of the outstanding balance, at December 31, 2014. No accruing commercial TDR loans were 60 days or more delinquent at March 31, 2015 and December 31, 2014.

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. 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 tables, 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.

The following table summarizes impaired loans.

(1)Related to subordinated bank notes with a stated maturity of 2025 at March 31, 2015.

At March 31, 2015, TCF Bank had pledged loans secured by residential real estate, commercial real estate and Federal Home Loan Bank (“FHLB”) stock with an aggregate carrying value of $4.9 billion as collateral for FHLB advances. At March 31, 2015, $350.0 million of FHLB advances outstanding were prepayable monthly at TCF’s option.

On February 27, 2015, TCF Bank issued $150.0 million of subordinated notes due February 27, 2025 with a fixed-rate coupon of 4.60% per annum (the “2025 Notes”), at a price to investors of 99.375%. In addition, TCF Bank incurred issuance costs of $1.4 million. Both the discount and issuance costs are amortized to interest expense over the respective term of the notes using the effective interest method. Interest is payable semi-annually, in arrears, on February 27 and August 27, commencing August 27, 2015. Simultaneously, TCF Bank entered into an interest rate swap with a total notional amount of $150.0 million designated as a fair value hedge. The effect of the interest rate swap is to effectively convert the fixed-rate on the 2025 Notes to a floating interest rate based on the three-month London InterBank Offered Rate (“LIBOR”) plus a fixed number of basis points on the $150.0 million notional amount. In exchange, TCF Bank will receive 4.60% fixed-rate interest based on the same notional amount from the swap counterparty. The gains and losses related to changes in the fair value of the interest rate swap are included in non-interest income in the Consolidated Statements of Income and substantially offset the change in the fair value of the hedged underlying debt that is attributable to the changes in market risk. The carrying value of the 2025 Notes was adjusted by an amount that is offset by the fair value of the interest rate swap. See Note 12 of Notes to Consolidated Financial Statements, Derivative Instruments, for additional information.

At March 31, 2015, all of the subordinated notes qualify as Tier 2 or supplementary capital for regulatory purposes, subject to certain regulatory limitations.

Note 9.  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 profits for the current year combined with its net retained profits for the preceding two calendar years, which was $349.4 million at March 31, 2015, without prior approval of the Office of the Comptroller of the Currency (“OCC”). 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. These capital adequacy standards may be higher in the future than existing minimum regulatory capital requirements.

The following table presents regulatory capital information for TCF and TCF Bank. Information presented for March 31, 2015 reflects the transition to the Basel III capital standard from previous regulatory capital adequacy guidelines under the Basel I framework. The Basel III capital standard phases in through 2019 and revises the definition of capital, increases minimum capital ratios, introduces regulatory capital buffers above those minimums, introduces a common equity Tier 1 capital ratio and revises the rules for calculating risk-weighted assets. Banks that are not advanced approaches institutions may make a one-time election to opt out of the requirement to include components of accumulated other comprehensive income (loss) in common equity Tier 1 capital. TCF has elected to opt-out of the accumulated other comprehensive income (loss) requirement. The adoption of the new capital standard had an immaterial impact to TCF’s capital levels and related ratios.

Unrecognized stock compensation expense for restricted stock awards and options was $22.0 million, excluding estimated forfeitures, with a weighted-average remaining amortization period of 2.4 years at March 31, 2015.

At March 31, 2015, there were 1,080,916 shares of performance-based restricted stock outstanding that will vest only if certain return on asset goals, loan volumes and credit quality metrics and service conditions are achieved. Failure to achieve the performance and service conditions will result in all or a portion of the shares being forfeited.

Note 12.  Derivative Instruments

All derivative instruments are recognized within other assets or other liabilities at fair value within the Consolidated Statements of Financial Condition. The value of derivative instruments will vary over their contractual terms as the related underlying rates fluctuate. The accounting for changes in the fair value of a derivative instrument depends on whether or not the contract has been designated and qualifies as a hedge. To qualify as a hedge, a contract must be highly effective at reducing the risk associated with the exposure being hedged. In addition, for a contract to be designated as a hedge, the risk management objective and strategy must be documented at inception. Hedge documentation must also identify the hedging instrument, the asset or liability and type of risk to be hedged and how the effectiveness of the contract is assessed prospectively and retrospectively. To assess effectiveness, TCF uses statistical methods such as regression analysis. A contract that has been, and is expected to continue to be, effective at offsetting changes in fair values or the net investment must be assessed and documented at least quarterly. If it is determined that a contract is not highly effective at hedging the designated exposure, hedge accounting is discontinued.

Upon origination of a derivative instrument, the contract is designated either as a hedge of the volatility of an investment in foreign operations driven by changes in foreign currency exchange rates (“net investment hedge”), a hedge of the exposure to changes in the fair value of an asset or liability due to changes in market risk (“fair value hedge”), or is not designated as a hedge. Changes in net investment hedges recorded within other comprehensive income (loss) are subsequently reclassified to non-interest expense during the period in which the foreign investment is substantially liquidated or when other elements of the currency translation adjustment are reclassified to income. If a hedged forecasted transaction is no longer probable, hedge accounting is discontinued and any gain or loss included in other comprehensive income (loss) is reported in earnings immediately.

Net Investment Hedges  Forward foreign exchange contracts, that generally settle within 30 days, are used to manage the foreign exchange risk associated with the Company’s net investment in TCF Commercial Finance Canada, Inc., a wholly-owned indirect Canadian subsidiary of TCF Bank.

Fair Value Hedges  During the first quarter of 2015, TCF Bank entered into an interest rate swap settled through a central clearing house.  The swap was designated as a fair value hedge and effectively converts the fixed interest rate to a floating rate based on three-month LIBOR plus a fixed number of basis points on the $150.0 million notional amount through February 27, 2025. In exchange, TCF Bank will receive 4.60% fixed-rate interest from the swap counterparty.

The interest rate swap substantially offsets the change in fair value of the hedged underlying debt that is attributable to the changes in market risk. The gains and losses related to changes in the fair value of the interest rate swap are reflected in non-interest income.

Derivatives Not Designated as Hedges  TCF executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged with offsetting interest rate swaps that TCF executes with a third party and settles through a central clearing house, such that TCF minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are reflected in non-interest income. These contracts have original fixed maturity dates ranging from three to ten years.

During the second quarter of 2012, TCF sold its Visa® Class B stock. In conjunction with the sale, TCF and the purchaser entered into a derivative transaction whereby TCF may receive or be required to make cash payments whenever the conversion ratio of the Visa Class B stock into Visa Class A stock is adjusted. The fair value of this derivative has been determined using estimated future cash flows using probability weighted scenarios for multiple estimates of Visa’s aggregate exposure to covered litigation matters, which include consideration of amounts funded by Visa into its escrow account for the covered litigation matters. Changes, if any, in the valuation of this swap agreement, which has no determinable maturity date, are reflected in non-interest income.

22

Certain of TCF’s forward foreign exchange contracts are not designated as hedges and are generally settled within 30 days. Changes in the fair value of these forward foreign exchange contracts are reflected in non-interest expense.

TCF enters into interest rate lock commitments in conjunction with certain consumer real estate loans. These interest rate lock commitments are agreements to extend credit under certain specified terms and conditions at fixed rates and have original lock expirations of up to 60 days. They are not designated as hedges and accordingly, changes in the valuation of these commitments are reflected in non-interest income.

The following tables summarize TCF’s outstanding derivative instruments as of March 31, 2015 and December 31, 2014. See Note 13, Fair Value Disclosures, for additional information.

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 March 31, 2015, credit risk-related contingent features existed on forward foreign exchange contracts with a notional value of $138.0 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 $2.8 million in additional collateral. There were no forward foreign exchange contracts containing credit risk-related features in a net liability position at March 31, 2015.

At March 31, 2015, TCF had posted $11.1 million, $1.4 million and $1.1 million of cash collateral related to its interest rate contracts, other contracts and its forward foreign exchange contracts, respectively.

Note 13.  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 and leases held for sale, forward foreign exchange contracts, interest rate contracts, other contracts, interest rate lock commitments, forward loan sales commitments and assets and liabilities held in trust for deferred compensation plans 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, interest-only strips, other real estate owned and repossessed and returned assets. These non-recurring fair value adjustments typically involve application of lower-of-cost-or-market accounting or write-downs of individual assets.

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

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.

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 certain other securities held to maturity, categorized as Level 3, is estimated based on discounted cash flows using current market rates and consideration of credit exposure or other internal pricing methods. 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. The fair value of securities of U.S. Government sponsored enterprises and federal agencies, 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 and Leases Held for Sale  Loans and leases held for sale are generally carried at the lower of cost or fair value. The cost of loans held for sale includes the unpaid principal balance, net of deferred loan fees and costs. Estimated fair values are based upon recent loan sale transactions and any available price quotes on loans with similar coupons, maturities and credit quality. Certain other loans and leases 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 and leases held for sale are categorized as Level 3.

25

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 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.

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, in accordance with GAAP, 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 swaps 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, such that TCF minimizes its net risk exposure resulting from such transactions. TCF also entered into an interest rate swap to convert its fixed-rate 2025 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.

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

Interest Rate Lock Commitments and Forward Loan Sales Commitments  TCF’s interest rate lock commitments are derivative instruments which 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 majority of the inputs significant in the valuation of these commitments fall within Level 3 and therefore they are categorized as Level 3.

Interest-Only Strips  The fair value of interest-only strips, categorized as Level 3, represents the present value of future cash flows retained 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

Other Real Estate Owned and Repossessed and Returned Assets  The fair value of other real estate owned 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 and repossessed and returned assets were written down $3.4 million and $3.3 million, which was included in foreclosed real estate and repossessed assets, net expense for the three months ended March 31, 2015 and 2014, respectively.

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.

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.

Assets and Liabilities Held in Trust for Deferred Compensation Plans  Assets held in trust for deferred compensation plans include investments in publicly traded stocks, 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 upon prices obtained from independent asset pricing services based on active markets. The fair value of the liabilities equals the fair value of the assets.

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, as commitments and standby letters of credit similar to TCF’s are not actively traded. 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 receivable and derivative payable balances 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 availability of 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 quarters ended March 31, 2015 and 2014.

Fair Value Option

In the third quarter of 2014, TCF initiated a correspondent lending program in which TCF Bank originates consumer mortgage loans and sells them to a wholesale partner. 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 following table presents the difference between the aggregate fair value and aggregate unpaid principal balance of these loans held for sale.

(In thousands)	At March 31, 2015		At December 31, 2014
Fair value carrying amount	$	6,248	$	3,308
Aggregate unpaid principal amount	6,057		3,205
Fair value carrying amount less aggregate unpaid principal	$	191	$	103

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 nonaccrual status at March 31, 2015 or December 31, 2014. The net gain from initial measurement of the above loans and subsequent changes in fair value for loans outstanding was $1.5 million for the three months ended March 31, 2015, and is included in gains on sales of consumer real estate loans, net. This amount excludes the impact from offsetting hedging arrangements 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 March 31, 2015 and December 31, 2014, 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.

30

The following tables present 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. 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 14.  Earnings Per Common Share

TCF’s restricted stock awards that pay non-forfeitable common stock dividends meet the criteria of a participating security. Accordingly, earnings per share is calculated using the two-class method, under which earnings are allocated to both common shares and participating securities.

	Three Months Ended March 31,
(Dollars in thousands, except per-share data)	2015			2014
Basic Earnings Per Common Share:

Weighted-average common shares outstanding for diluted earnings per common share	165,365,634			163,267,168
Diluted earnings per common share	$	0.21		$	0.24

All shares of restricted stock are deducted from weighted-average shares outstanding for the computation of basic earnings per common share. Shares of performance-based restricted stock are included in the calculation of diluted earnings per common share, using the treasury stock method, at the beginning of the quarter in which the performance goals have been achieved. All other shares of restricted stock, which vest over specified time periods, stock options and warrants are included in the calculation of diluted earnings per common share, using the treasury stock method.

For the three months ended March 31, 2015 and 2014, there were 4.4 million and 3.7 million, respectively, of outstanding shares related to non-participating restricted stock, stock options and warrants that were not included in the computation of diluted earnings per share because they were anti-dilutive.

Note 15.  Business Segments

Lending, Funding and Support Services have been identified as reportable segments. Lending includes consumer real estate, commercial real estate and business lending, leasing and equipment finance, inventory finance and auto finance. Funding includes branch banking and treasury services. Support Services includes Holding Company and corporate functions that provide data processing, bank operations and other professional services to the operating segments.

TCF evaluates performance and allocates resources based on each segment’s net income or loss. The business segments follow GAAP as described in Note 1, Summary of Significant Accounting Policies, in Item 8 of TCF’s most recent Annual Report on Form 10-K. TCF generally accounts for inter-segment sales and transfers at cost.

Note 16.  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 enforcement actions brought by federal regulators, including the Securities and Exchange Commission (“SEC”), the Federal Reserve, the OCC and the Consumer Financial Protection Bureau. 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. 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. TCF is also subject to regulatory examinations, and TCF’s regulatory authorities may impose sanctions on TCF for failures related to regulatory compliance.

TCF FINANCIAL CORPORATION AND SUBSIDIARIES

Item 2.  Management’s Discussion and Analysis of Financial

Condition and Results of Operations

Overview

TCF Financial Corporation, a Delaware corporation (“we,” “us,” “our,” “TCF,” or the “Company”), is a national bank holding company based in Wayzata, Minnesota. Unless otherwise indicated, references herein to “TCF” include its direct and indirect subsidiaries. Its principal subsidiary, TCF National Bank (“TCF Bank”), is headquartered in Sioux Falls, South Dakota. References herein to “TCF Financial” refer to TCF Financial Corporation on an unconsolidated basis. At March 31, 2015, TCF had 379 branches in Illinois, Minnesota, Michigan, Colorado, Wisconsin, Arizona, South Dakota and Indiana (TCF’s primary banking markets).

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 branches that are open seven days a week in all markets and on most holidays, extensive full-service supermarket branches, automated teller machine (“ATM”) networks and internet, mobile and telephone banking. 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 through electronic channels and acquisitions of portfolios or companies. New products and services are designed to build on existing businesses and expand into complementary products and services through strategic initiatives. Funded through deposit generation,TCF continues to focus on asset growth in its leasing and equipment finance, inventory finance and auto finance businesses, as well as expanding its junior lien lending business.

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 66.9% and 66.1% of TCF’s total revenue for the first quarter of 2015 and 2014, respectively. Net interest income can change significantly from period to period based on general levels of interest rates, customer prepayment patterns, the mix of interest-earning assets and the mix of interest-bearing and non-interest bearing deposits and 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” and “Part II, Item 1A. Risk Factors” for further discussion.

Non-interest income is a significant source of revenue for TCF and an important component of TCF’s results of operations. Increasing fee and service charge revenue has been challenging as a result of changing consumer behavior and the impact of changes in regulations. Providing a wide range of retail banking services is an integral component of TCF’s business philosophy and a major strategy for generating non-interest income. Key drivers of bank fees and service charges are the number of deposit accounts and related transaction activity. In addition, as an effort to diversify TCF’s non-interest income sources, the Company continues to sell loans, primarily in auto finance and consumer real estate, to generate gains on sales as well as increase servicing fee income through the growth of loans sold with servicing retained by TCF.

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 first quarter of 2015 and 2014, and on information about TCF’s balance sheet, loan and lease portfolio, liquidity, funding resources, capital and other matters.

36

Results of Operations

Performance Summary  TCF reported diluted earnings per common share of 21 cents for the first quarter of 2015, compared with diluted earnings per common share of 24 cents for the first quarter of 2014. TCF reported net income of $39.8 million for the first quarter of 2015, compared with net income of $44.8 million for the first quarter of 2014.

Return on average assets was 0.85% for the first quarter of 2015, compared with 1.00% for the first quarter of 2014. Return on average common equity was 7.47% for the first quarter of 2015, compared with 9.35% for the first quarter of 2014.

Reportable Segment Results

Lending  TCF’s lending strategy is primarily to originate high credit quality secured loans and leases for investment and for sale. The lending portfolio consists of consumer real estate, commercial real estate and business lending, leasing and equipment finance, inventory finance and auto finance. Lending’s disciplined portfolio growth generates earning assets and, along with its fee generating capabilities, produces a significant portion of the Company’s revenue and net income. Lending generated net income available to common stockholders of $47.5 million for the first quarter of 2015, compared with $46.7 million for the same period in 2014.

Lending net interest income totaled $153.4 million for the first quarter of 2015, an increase of 5.9% from $144.8 million for the same period in 2014. The increase was primarily driven by higher average loan and lease balances in the auto finance, leasing and equipment finance and inventory finance businesses. This increase was partially offset by downward pressure on yields across the lending businesses in this increasingly competitive low interest rate environment, lower average balances of higher yielding fixed-rate loans in the consumer real estate and commercial portfolios due to run-off exceeding originations, and the troubled debt restructuring (“TDR”) loan sale in December 2014.

Lending provision for credit losses totaled $12.6 million for the first quarter of 2015, a decrease of 11.3% from $14.2 million for the same period in 2014. The decrease was primarily due to reduced reserve requirements and net charge-offs in the consumer real estate portfolio as a result of improved credit quality.

Lending non-interest income totaled $48.6 million for the first quarter of 2015, a decrease of 5.3% from $51.3 million for the same period in 2014. The decrease was primarily due to a decrease in net gains on sales of consumer real estate  loans and auto loans, partially offset by an increase in servicing fee income due to an increase in the portfolio of loans serviced for others.

Lending non-interest expense totaled $112.5 million for the first quarter of 2015, an increase of 6.7% from $105.5 million for the same period in 2014. The increase was primarily due to increased staff levels to support the auto finance and consumer real estate businesses and the continued investment in risk management.

37

Funding  TCF’s funding is primarily derived from branch banking and wholesale borrowings, with a focus on building and maintaining quality customer relationships. Deposits are generated from consumers and small businesses providing a source of low cost funds and fee income. Borrowings may be used to offset reductions in deposits or to support lending activities. Funding reported net loss available to common stockholders of $7.0 million for the first quarter of 2015, compared with net loss available to common stockholders of $0.1 million for the same period in 2014.

Funding net interest income totaled $50.8 million for the first quarter of 2015, a decrease of 11.2% from $57.2 million for the same period in 2014. The decrease was primarily due to increased average rates on certificates of deposit accounts as a result of deposit campaigns to fund loan and lease growth at market rates.

Funding non-interest income totaled $50.2 million for the first quarter of 2015, a decrease of 2.8% from $51.7 million for the same period in 2014. The decrease was primarily due to a reduction in fees and service charges due to consumer behavior changes, as well as higher average checking account balances per customer.

Funding non-interest expense totaled $111.8 million for the first quarter of 2015, an increase of 2.8% from $108.7 million for the same period in 2014. The increase was primarily due to the continued investment in risk management.

Consolidated Income Statement Analysis

Net Interest Income  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 66.9% of TCF’s total revenue for the first quarter of 2015, compared with 66.1% for the first quarter of 2014. Net interest income 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 changes in prevailing short- and long-term interest rates, loan and deposit pricing strategies and competitive conditions, the volume and the mix of interest-earning assets and both non-interest bearing deposits and interest-bearing liabilities, the level of non-accrual loans and leases and other real estate owned and the impact of modified loans and leases.

Net interest income, including the impact of tax-equivalent adjustments of $0.8 million, was $204.2 million for the first quarter of 2015, an increase of 1.1% from $202.0 million for the same period of 2014. This increase was primarily driven by higher average loan and lease balances in the auto finance, leasing and equipment finance and inventory finance businesses. This increase was mostly offset by downward pressure on yields across the lending businesses in this increasingly competitive low interest rate environment, lower average balances of higher yielding fixed-rate loans in the consumer real estate and commercial portfolios due to run-off exceeding originations and the TDR loan sale in December 2014, the proceeds of which are expected to be reinvested in our core businesses over the next several quarters.

Net interest margin was 4.50% and 4.66% for the first quarter of 2015 and 2014, respectively. The decrease was primarily due to margin compression resulting from the competitive low interest rate environment.

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 methodologies for determining and allocating the allowance for loan and lease losses and the related provision for credit losses focus on historical trends in net charge-offs, delinquencies in the loan and lease portfolio, value of collateral, general economic conditions and management’s assessment of credit risk in the current loan and lease portfolio.

The following table summarizes the composition of TCF’s provision for credit losses for the first quarter of 2015 and 2014.

	Three Months Ended March 31,								Change
(Dollars in thousands)	2015				2014				$			%
Consumer real estate	$	2,819	22.0	%	$	7,079	48.8	%	$	(4,260	)	(60.2)%

Total	$	12,791	100.0	%	$	14,492	100.0	%	$	(1,701	)	(11.7)

TCF provided $12.8 million for credit losses for the first quarter of 2015, compared with $14.5 million for the first quarter of 2014. The decrease was primarily due to reduced reserve requirements and net charge-offs in the consumer real estate portfolio as a result of improved credit quality, partially offset by an increase in auto finance and inventory finance reserve requirements due to growth in the portfolios.

Net loan and lease charge-offs were $11.5 million for the first quarter of 2015, or 0.28% (annualized) of average loans and leases, compared with $17.4 million, or 0.43% (annualized) for the same period in 2014. The decrease was primarily due to improved credit quality in the consumer real estate and commercial portfolios.

Non-Interest Income  Non-interest income is a significant source of revenue for TCF, representing 33.1% of total revenues for the first quarter of 2015, compared with 33.9% for the same period in 2014, and is an important factor in TCF’s results of operations. Total fees and other revenue were $100.7 million for the first quarter of 2015, compared with $103.0 million for the same period in 2014.

Fees and Service Charges  Fees and service charges totaled $34.0 million for the first quarter of 2015, compared with $36.6 million for the same period in 2014. The decrease was primarily due to consumer behavior changes, as well as higher average checking account balances per customer.

Card Revenue  Card revenue, primarily interchange fees, totaled $12.9 million for the first quarter of 2015, compared with $12.3 million for the same period in 2014. The increase was primarily due to increased transaction volume.

TCF is the 17th largest issuer of Visa® consumer debit cards and the 13th largest issuer of Visa small business debit cards in the United States, based on payment volume for the three months ended December 31, 2014, as provided by Visa. TCF earns interchange revenue from customer card transactions paid primarily by merchants, not TCF’s customers. Card revenue represented 24.8% of banking fee revenue for the first quarter of 2015, compared with 22.6% for the same period in 2014.

Gains on Sales of Auto Loans, Net  TCF sold $203.5 million of auto loans and recognized net gains of $6.7 million for the first quarter of 2015, compared with sales of $261.7 million of auto loans with recognized net gains of $8.8 million for the same period in 2014. The decrease was due to more loans being held on the balance sheet.

Gains on Sales of Consumer Real Estate Loans, Net  TCF sold $264.3 million of consumer real estate loans and recognized net gains of $8.2 million for the first quarter of 2015, compared with sales of $347.4 million of consumer real estate loans with recognized net gains of $11.7 million for the same period in 2014. The decrease was due to more loans held on the balance sheet.

Servicing Fee Income  Servicing fee income totaled $7.3 million for the first quarter of 2015, compared with $4.3 million for the same period in 2014. The increase was primarily due to an increase in the portfolio of consumer real estate and auto loans sold with servicing retained by TCF. Total loans and leases serviced for others was $3.5 billion as of March 31, 2015, compared with $2.4 billion as of March 31, 2014.

Other  Other non-interest income totaled $4.1 million for the first quarter of 2015, compared with $2.4 million for the same period in 2014. The increase was primarily due to a gain of $1.7 million related to appreciation of a private bank investment related to the bank’s merger with a publicly held financial institution.

Non-Interest Expense  Total non-interest expense was $226.8 million for the first quarter of 2015, compared with $217.1 million for the same period in 2014.

FDIC Insurance  FDIC premium expense totaled $5.4 million for the first quarter of 2015, compared with $7.6 million for the same period in 2014. The decrease was due to a lower assessment rate primarily as a result of the TDR loan sale in December 2014 and improved credit metrics.

Other  Other non-interest expense totaled $48.1 million for the first quarter of 2015, compared with $41.3 million for the same period in 2014. The increase was primarily due to the donation of an investment with a carrying value of $2.8 million, to the TCF Foundation during the first quarter of 2015.

Income Taxes  Income tax expense was $22.8 million for the first quarter of 2015, or 35.4% of income before income tax expense, compared with $26.6 million, or 36.4% for the same period in 2014.

Consolidated Financial Condition Analysis

Loans and Leases  Total loans and leases were $17.1 billion at March 31, 2015, an increase of 4.0%, from $16.4 billion at December 31, 2014, primarily driven by growth in the inventory finance and auto finance portfolios.

Consumer Real Estate  The consumer real estate portfolio consisted of $3.0 billion and $2.6 billion of first mortgage lien loans and junior lien loans, respectively, at March 31, 2015, a decrease of 4.1% and an increase of 2.2%, respectively, from $3.1 billion and $2.5 billion, respectively, at December 31, 2014. At March 31, 2015, 49.2% of the consumer real estate portfolio carried a variable interest rate tied to the prime rate, compared with 47.7% at December 31, 2014. At March 31, 2015, 57.3% of TCF’s consumer real estate loans consisted of closed-end loans, compared with 59.1% at December 31, 2014. 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 lending portfolio was 731 and 734 as of March 31, 2015 and December 31, 2014, respectively. As part of TCF’s credit risk monitoring, TCF obtains updated FICO score information quarterly. The average updated FICO score for the retail lending portfolio was 730 at both March 31, 2015 and December 31, 2014. Outstanding balances on consumer real estate lines of credit were $2.4 billion and $2.3 billion at March 31, 2015 and December 31, 2014, respectively. At March 31, 2015, 52.5% of the consumer real estate loan balance had been originated since January 1, 2009 with annualized net charge-offs of less than 0.1%.

Commercial Real Estate and Business Lending  The commercial real estate and business lending portfolio consisted of $2.6 billion and $0.6 billion of commercial real estate loans and commercial business loans, respectively, at March 31, 2015, an increase of 0.5% and 6.7%, respectively, from $2.6 billion and $0.5 billion, respectively, at December 31, 2014. At March 31, 2015, 86.5% of TCF’s commercial real estate loans outstanding were secured by properties located in its primary banking markets, compared with 88.3% at December 31, 2014. With an emphasis on secured lending, 99.9% of TCF’s total commercial loans were secured either by properties or other business assets at both March 31, 2015 and December 31, 2014. Variable and adjustable-rate loans represented 61.2% of the total commercial loans outstanding at March 31, 2015, compared with 58.3% at December 31, 2014.

Leasing and Equipment Finance   The leasing and equipment finance portfolio consisted of $1.9 billion of leases and $1.8 billion of loans at both March 31, 2015 and  December 31, 2014. The uninstalled backlog of approved transactions was $463.5 million at March 31, 2015, compared with $418.0 million at December 31, 2014.

Inventory Finance  Inventory finance loans totaled $2.3 billion at March 31, 2015, an increase of 24.5% from $1.9 billion at December 31, 2014, primarily due to seasonal inventory increases within lawn and garden, combined with growth in the powersports and other segments.

Auto Finance  Auto finance loans totaled $2.2 billion at March 31, 2015, an increase of 12.6% from $1.9 billion at December 31, 2014. The increase was due to continued growth as TCF expands the number of active dealers in its network. The auto finance network included dealers in all 50 states with more than 10,800 active dealers at March 31, 2015, compared with more than 10,500 active dealers at December 31, 2014. The auto finance portfolio consisted of 25.7% new car loans and 74.3% used car loans at March 31, 2015, compared with 25.4% and 74.6%, respectively, at December 31, 2014. The average original FICO score for the auto finance portfolio was 724 at both March 31, 2015 and December 31, 2014.

Loan Modifications  The following table provides a summary of accruing TDR loans.

(Dollars in thousands)	At March 31, 2015			At December 31, 2014
Consumer real estate	$	111,714		$	111,933
Commercial	55,086			80,375

Other	21			89
Total	$	167,759		$	193,848
Over 60-day delinquency as a percentage of total accruing TDR loans	1.53		%	1.39		%

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.

43

Under consumer real estate programs, TCF typically reduces a customer’s contractual payments 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. Due to clarifying regulatory guidance adopted in the first quarter of 2014, these loans may now return to accrual status when TCF expects full repayment of the remaining pre-discharged contractual principal and interest. Although loans classified as TDR loans are considered impaired, TCF received more than 59% of the original contractual interest due on accruing consumer real estate TDR loans during the first quarter of 2015, yielding 3.9%, by modifying the loans to qualified customers instead of foreclosing on the property.

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 March 31, 2015, 81.8% of total commercial TDR loans were accruing and TCF recognized more than 91% of the original contractual interest due on accruing commercial TDR loans during the first quarter of 2015. At March 31, 2015, collection of principal and interest under the modified terms was reasonably assured on all accruing commercial TDR loans.

TCF utilizes a multiple note structure as a workout alternative for certain commercial loans, which restructures a troubled loan into two notes. When utilizing this multiple note structure, the first note is always classified as a TDR loan. Under TCF policy, the first note is established at an amount and with market terms that provide reasonable assurance of payment and performance. If the loan was modified at an interest rate equal to the yield of a new loan originated with comparable risk at the time of restructuring and the loan is performing based on the terms of the restructuring agreement, this note may be removed from TDR loan classification in the calendar year after modification. This note is reported on accrual status if the loan has been formally restructured so as to be reasonably assured of payment and performance according to its modified terms. This evaluation includes consideration of the customer’s payment performance for a reasonable period of at least six consecutive months, which may include time prior to the restructuring, before the loan is returned to accrual status. The second note is charged-off. This second note is a separate and distinct legal contract and is still outstanding. Should the borrower’s financial position improve, the loan may become recoverable. At March 31, 2015, one TDR loan restructured as multiple notes with a combined total contractual balance of $11.2 million and a remaining book balance of $10.7 million is included in the preceding table.

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

The following table summarizes TCF’s non-accrual TDR loans included in the table above.

(In thousands)	At March 31, 2015		At December 31, 2014
Consumer real estate	$	86,962	$	87,685

Inventory finance	686		37
Auto finance	4,483		3,676
Total	$	105,934	$	104,616

Consumer real estate loans are generally placed on non-accrual status once they become 90 days past due and are charged-off to the estimated fair value of underlying collateral, less estimated selling costs, no later than 150 days past due. Commercial loans are generally placed on non-accrual status once they become 90 days past due unless they are well secured and in the process of collection. Auto loans are generally charged-off to the fair value of the collateral, less estimated selling costs, upon entering non-accrual status no later than 120 days past due. Any necessary additional reserves are established for commercial loans, leasing and equipment finance loans and leases, and inventory finance loans when reported as non-accrual. 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.

Changes in the amount of non-accrual loans and leases for the three months ended March 31, 2015 are summarized in the following table.

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

The following tables summarize accruing loans and leases by portfolio and regulatory classification and non-accrual loans and leases by portfolio.

The combined balance of accruing classified loans and leases and non-accrual loans and leases was $483.5 million at March 31, 2015, an increase of $31.8 million from December 31, 2014, primarily due to an increase in inventory finance classified loans. Included in the table above in the non-accrual column are $52.4 million and $50.0 million of consumer loans discharged in Chapter 7 bankruptcy that were not reaffirmed at March 31, 2015 and December 31, 2014, respectively.

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, the portfolios’ overall risk characteristics, changes in its character or size, risk rating migration,  delinquencies, collateral values 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 $163.8 million appropriate to cover losses incurred in the loan and lease portfolios at March 31, 2015. 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 that subsequent evaluations of the loan and lease portfolios, in light of factors then prevailing, including economic conditions, TCF’s ongoing credit review process or regulatory requirements, will not require significant changes in the balance of the allowance for loan and lease losses. Among other factors, an economic slowdown, increasing levels of unemployment and/or a decline in commercial or residential real estate values in TCF’s markets 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.

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 of Notes to Consolidated Financial Statements, Allowance for Loan and Lease Losses and Credit Quality Information, the following table includes detailed information regarding TCF’s allowance for loan and lease losses.

At March 31, 2015, the allowance as a percent of total loans and leases decreased to 0.96%, compared with 1.00% at December 31, 2014. This decrease was driven by reduced reserves in the consumer real estate portfolio resulting from improved home values.

Other Real Estate Owned and Repossessed and Returned Assets  Other real estate owned and repossessed and returned assets are summarized in the following table.

(In thousands)	At March 31, 2015		At December 31, 2014
Other real estate owned:(1)

Total other real estate owned and repossessed and returned assets	$	66,806	$	69,175

(1)Includes properties owned and foreclosed properties subject to redemption.

Total consumer real estate properties reported in other real estate owned included 271 owned properties and 158 foreclosed properties subject to redemption at March 31, 2015, compared with 277 owned properties and 146 foreclosed properties subject to redemption at December 31, 2014. The decrease in owned properties from December 31, 2014 resulted from sales of 149 properties, partially offset by the addition of 143 properties. The average length of time of consumer real estate properties sold during the first quarter of 2015 was approximately 5.8 months from the date the properties were listed for sale. Consumer real estate loans in process of foreclosure were $42.1 million and $46.1 million at March 31, 2015 and December 31, 2014, respectively.

The changes in the amount of other real estate owned for the first quarter of 2015 are summarized in the following table.

Liquidity Management  Deposits are the primary source of TCF’s funds for use in lending and for other general business purposes. In addition to deposits, TCF derives 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.

TCF Bank had $565.0 million and $767.0 million of net liquidity qualifying interest-bearing deposits at the Federal Reserve Bank at March 31, 2015 and December 31, 2014, respectively. Interest-bearing deposits held at the Federal Reserve Bank and unencumbered securities were $1.3 billion and $1.4 billion at March 31, 2015 and December 31, 2014, respectively.

The primary source of funding for TCF Commercial Finance Canada, Inc. (“TCFCFC”) is a line of credit with TCF Bank. Primarily for contingency purposes, TCFCFC maintains a $20.0 million Canadian dollar-denominated line of credit facility with a counterparty, which is guaranteed by TCF Bank. At March 31, 2015, TCFCFC had $5.5 million (USD) outstanding under the line of credit with the counterparty.

Deposits  Deposits totaled $16.0 billion at March 31, 2015, an increase of $0.5 billion, or 3.3%, from December 31, 2014, primarily due to special campaigns for money market accounts and higher average checking account balances per customer.

48

Checking, savings and money market deposits are an important source of low interest cost funds for TCF. These deposits totaled $12.9 billion at March 31, 2015, an increase of $0.5 billion from December 31, 2014, and comprised 80.8% of total deposits at March 31, 2015, compared with 80.3% of total deposits at December 31, 2014. The average balance of these forms of deposits for the first quarter of 2015 was $12.6 billion, an increase of $0.6 billion from the $12.0 billion average balance for the first quarter of 2014.

Certificates of deposit totaled $3.1 billion at March 31, 2015, compared with $3.0 billion at December 31, 2014.

Non-interest bearing checking represented 19.2% of total deposits at March 31, 2015, compared with 18.3% at December 31, 2014. TCF’s weighted-average rate for deposits, including non-interest bearing deposits, was 0.29% at March 31, 2015, compared with 0.26% at December 31, 2014. The increase was primarily due to increased average rates on money market and certificates of deposit accounts as a result of deposit campaigns to fund loan and lease growth at market rates.

Borrowings  Borrowings totaled $1.2 billion at both March 31, 2015 and December 31, 2014. Historically, TCF has borrowed primarily from the Federal Home Loan Bank (“FHLB”) of Des Moines, institutional sources under repurchase agreements and other sources. At March 31, 2015, TCF had $2.5 billion of unused, secured borrowing capacity at the FHLB of Des Moines.

On February 27, 2015, TCF Bank issued $150.0 million of subordinated notes due February 27, 2025 with a fixed-rate coupon of 4.60% per annum. Simultaneously, TCF Bank entered into an interest rate swap agreement designated as a fair value hedge. The effect of the interest rate swap is to effectively convert the fixed-rate on the subordinated notes to a floating interest rate based on the three-month LIBOR plus a fixed number of basis points on the notional amount.

See Note 7 and Note 8 of Notes to Consolidated Financial Statements, Short-term Borrowings and Long-term Borrowings, respectively, for additional information regarding TCF’s borrowings.

Capital Management  TCF is committed to managing capital to maintain protection for 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 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, or the declaration of preferred stock, common stock or 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’s capital levels are managed in such a manner that all regulatory capital requirements for well-capitalized banks and bank holding companies are exceeded. At March 31, 2015 and December 31, 2014, regulatory capital for TCF and TCF Bank exceeded their respective regulatory capital requirements. See Note 9 of Notes to Consolidated Financial Statements, Regulatory Capital Requirements.

Preferred Stock  At March 31, 2015, there were 6,900,000 depositary shares outstanding, each representing a 1/1,000th interest in a share of the Series A Non-Cumulative Perpetual Preferred Stock of TCF Financial Corporation, par value $.01 per share, with a liquidation preference of $25,000 per share (equivalent to $25 per depositary share)(“Series A Preferred Stock”). Dividends are 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 7.5%. At March 31, 2015, there were 4,000,000 shares outstanding of 6.45% Series B Non-Cumulative Perpetual Preferred Stock of TCF Financial Corporation, par value $.01 per share, with a liquidation preference of $25 per share (“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%.

49

Equity  Total equity at March 31, 2015 was $2.2 billion, or 10.9% of total assets, compared with $2.1 billion, or 11.0% of total assets, at December 31, 2014. Dividends to common stockholders on a per share basis totaled 5 cents for the quarters ended March 31, 2015 and 2014. TCF’s common dividend payout ratio was 23.8% and 20.8% for the quarters ended March 31, 2015 and 2014, respectively. TCF Financial’s primary funding sources for dividends are earnings and dividends received from TCF Bank.

At March 31, 2015, 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.

Tangible common equity at March 31, 2015 was $1.7 billion, or 8.44% of total tangible assets, compared with $1.6 billion, or 8.50% of total tangible assets, at December 31, 2014. Tangible common equity is not a financial measure recognized under generally accepted accounting principles in the United States (“GAAP”) (i.e., non-GAAP). Tangible common equity represents total equity less preferred stock, goodwill, other intangible assets and non-controlling interest in subsidiaries. Tangible assets represent total assets less goodwill and other intangible assets. 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 provides investors, regulators and other users with information to be viewed in relation to other banking institutions.

The following table includes reconciliations of the non-GAAP financial measures of tangible common equity and tangible assets to the GAAP measures of total equity and total assets, respectively.

Recent Accounting Developments

In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”), No. 2015-05, Intangibles-Goodwill and Other- Internal-Use Software (Subtopic 350-40); Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, which updates guidance about whether a cloud computing arrangement includes a software license, and how to account for those software licenses. The adoption of this ASU will be required on either a retrospective or prospective basis beginning with TCF’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2016. Early adoption is allowed. Management is currently evaluating the potential impact of this guidance on our consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-04, Compensation-Retirement Benefits (Topic 715): Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets, which allows employers with fiscal year ends that do not coincide with a calendar month end to make an accounting policy election to measure defined benefit plan assets and obligations as of the end of the month closest to their fiscal year ends. 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, 2016. Early adoption is allowed. The adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from that debt liability, consistent with the presentation of a debt discount. 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, 2016. Early adoption is allowed. The adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 820): Amendments to the Consolidation Analysis, which changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. 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, 2016. The adoption of this ASU is not expected to have a material impact 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. The adoption of this ASU 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, 2017. Management is currently evaluating the potential impact of this guidance on our consolidated financial statements.

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.

53

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, such as credit risk, liquidity risk, operational and other risks in the normal course of its business, the Company considers interest rate risk to be one of its more significant market risks. 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-term and long-term interest rates, as well as variable interest rate indices (e.g., the prime rate or LIBOR).

TCF’s management Asset & Liability Committee (“ALCO”) manages TCF’s interest rate risk based on interest rate expectations and other factors. The principal objective of TCF’s management asset and liability activities 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.

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 re-pricings and events outside management’s control, such as customer 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, changes in market conditions, customer 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 re-pricing.

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)	March 31, 2015				December 31, 2014
Immediate Change in Interest Rates:
+200 basis points	$	81.5	9.7	%	$	73.6	8.9	%
+100 basis points	43.6		5.2		39.4		4.7

As of March 31, 2015, 52.9% of TCF’s loan and lease balances will reprice or are expected to pay down in the next 12 months and 63.8% of TCF’s deposit balances are low cost or no cost deposits. The mix of assets repricing compared with low cost or no cost deposits should enable TCF to increase net interest income when interest rates rise.

Management also uses economic value of equity (“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. Interest rate gap is the difference between interest-earning assets and interest-bearing liabilities re-pricing within a given period and represents the net asset or liability sensitivity at a point in time.

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 March 31, 2015.

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 SEC’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 March 31, 2015, 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 enforcement actions brought by federal regulators, including the Securities and Exchange Commission, the Federal Reserve, the OCC and the Consumer Financial Protection Bureau. 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. 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. TCF is also subject to regulatory examinations, and TCF’s regulatory authorities may impose sanctions on TCF for failures related to regulatory compliance.

Item 1A.  Risk Factors

There were no material changes in risk factors for TCF in the quarter covered by this report. You should carefully consider the risks and risk factors included under Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. TCF’s business, financial condition or results of operations could be materially adversely affected by any of these risks.

The authorization was for a repurchase of up to an additional 5% of TCF’s common stock outstanding at the time of the authorization, or 6.5 million shares. TCF has not repurchased shares since October 2007. Future repurchases will be based upon capital levels, growth expectations and market opportunities and may be subject to regulatory approval.

Cash and Due from Banks

Cash and Due from Banks

At March 31, 2015 and December 31, 2014, TCF Bank was required by Federal Reserve regulations to maintain reserves of $95.0 million and $98.7 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 sale and servicing of auto loans and consumer real estate loans. Cash payments received on loans serviced for third parties are generally held in separate accounts until remitted. TCF also retains cash balances for collateral on certain borrowings, forward foreign exchange contracts and interest rate contracts. TCF maintained restricted cash totaling $91.9 million and $67.8 million at March 31, 2015 and December 31, 2014, respectively.

TCF had cash held in interest-bearing accounts of $628.6 million and $842.1 million at March 31, 2015 and December 31, 2014, respectively.

Regulatory Capital Requirements [Abstract]

Schedule of regulatory capital information for TCF and TCF Bank

The following table presents regulatory capital information for TCF and TCF Bank. Information presented for March 31, 2015 reflects the transition to the Basel III capital standard from previous regulatory capital adequacy guidelines under the Basel I framework. The Basel III capital standard phases in through 2019 and revises the definition of capital, increases minimum capital ratios, introduces regulatory capital buffers above those minimums, introduces a common equity Tier 1 capital ratio and revises the rules for calculating risk-weighted assets. Banks that are not advanced approaches institutions may make a one-time election to opt out of the requirement to include components of accumulated other comprehensive income (loss) in common equity Tier 1 capital. TCF has elected to opt-out of the accumulated other comprehensive income (loss) requirement. The adoption of the new capital standard had an immaterial impact to TCF's capital levels and related ratios.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

TCF Financial Corporation, a Delaware corporation ("we," "us," "our," "TCF," or the "Company"), is a national bank holding company based in Wayzata, Minnesota. Unless otherwise indicated, references herein to "TCF" include its direct and indirect subsidiaries. Its principal subsidiary, TCF National Bank ("TCF Bank"), is headquartered in South Dakota. References herein to "TCF Financial" refer to TCF Financial Corporation on an unconsolidated basis.

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 generally accepted accounting principles in the United States ("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, 2014, and for the year then ended. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior period financial statements to conform to the current period presentation. Accounting policies in effect at December 31, 2014 remain significantly unchanged and will be 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 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.

Fair value of assets and liabilities, including hierarchy level

The following tables present 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. 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.

Segment Reporting [Abstract]

Business Segments

Business Segments

Lending, Funding and Support Services have been identified as reportable segments. Lending includes consumer real estate, commercial real estate and business lending, leasing and equipment finance, inventory finance and auto finance. Funding includes branch banking and treasury services. Support Services includes Holding Company and corporate functions that provide data processing, bank operations and other professional services to the operating segments.

TCF evaluates performance and allocates resources based on each segment's net income or loss. The business segments follow GAAP as described in Note 1, Summary of Significant Accounting Policies, in Item 8 of TCF's most recent Annual Report on Form 10-K. TCF generally accounts for inter-segment sales and transfers at cost.

The following table sets forth certain information for each of TCF's reportable segments, including a reconciliation of TCF's consolidated totals.

The tax effect of these reclassifications was recorded in income tax expense in the Consolidated Statements of Income. See Note 11, Employee Benefit Plans, for additional information regarding TCF's recognized postretirement prior service cost.

Unrecognized stock compensation expense for restricted stock awards and options was $22.0 million, excluding estimated forfeitures, with a weighted-average remaining amortization period of 2.4 years at March 31, 2015.

At March 31, 2015, there were 1,080,916 shares of performance-based restricted stock outstanding that will vest only if certain return on asset goals, loan volumes and credit quality metrics and service conditions are achieved. Failure to achieve the performance and service conditions will result in all or a portion of the shares being forfeited.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

Derivative Instruments

All derivative instruments are recognized within other assets or other liabilities at fair value within the Consolidated Statements of Financial Condition. The value of derivative instruments will vary over their contractual terms as the related underlying rates fluctuate. The accounting for changes in the fair value of a derivative instrument depends on whether or not the contract has been designated and qualifies as a hedge. To qualify as a hedge, a contract must be highly effective at reducing the risk associated with the exposure being hedged. In addition, for a contract to be designated as a hedge, the risk management objective and strategy must be documented at inception. Hedge documentation must also identify the hedging instrument, the asset or liability and type of risk to be hedged and how the effectiveness of the contract is assessed prospectively and retrospectively. To assess effectiveness, TCF uses statistical methods such as regression analysis. A contract that has been, and is expected to continue to be, effective at offsetting changes in fair values or the net investment must be assessed and documented at least quarterly. If it is determined that a contract is not highly effective at hedging the designated exposure, hedge accounting is discontinued.

Upon origination of a derivative instrument, the contract is designated either as a hedge of the volatility of an investment in foreign operations driven by changes in foreign currency exchange rates ("net investment hedge"), a hedge of the exposure to changes in the fair value of an asset or liability due to changes in market risk ("fair value hedge"), or is not designated as a hedge. Changes in net investment hedges recorded within other comprehensive income (loss) are subsequently reclassified to non-interest expense during the period in which the foreign investment is substantially liquidated or when other elements of the currency translation adjustment are reclassified to income. If a hedged forecasted transaction is no longer probable, hedge accounting is discontinued and any gain or loss included in other comprehensive income (loss) is reported in earnings immediately.

Net Investment Hedges  Forward foreign exchange contracts, that generally settle within 30 days, are used to manage the foreign exchange risk associated with the Company's net investment in TCF Commercial Finance Canada, Inc., a wholly-owned indirect Canadian subsidiary of TCF Bank.

Fair Value Hedges During the first quarter of 2015, TCF Bank entered into an interest rate swap settled through a central clearing house. The swap was designated as a fair value hedge and effectively converts the fixed interest rate to a floating rate based on three-month LIBOR plus a fixed number of basis points on the $150.0 million notional amount through February 27, 2025. In exchange, TCF Bank will receive 4.60% fixed-rate interest from the swap counterparty.

The interest rate swap substantially offsets the change in fair value of the hedged underlying debt that is attributable to the changes in market risk. The gains and losses related to changes in the fair value of the interest rate swap are reflected in non-interest income.

Derivatives Not Designated as Hedges  TCF executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged with offsetting interest rate swaps that TCF executes with a third party and settles through a central clearing house, such that TCF minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are reflected in non-interest income. These contracts have original fixed maturity dates ranging from three to ten years.

During the second quarter of 2012, TCF sold its Visa^® Class B stock. In conjunction with the sale, TCF and the purchaser entered into a derivative transaction whereby TCF may receive or be required to make cash payments whenever the conversion ratio of the Visa Class B stock into Visa Class A stock is adjusted. The fair value of this derivative has been determined using estimated future cash flows using probability weighted scenarios for multiple estimates of Visa's aggregate exposure to covered litigation matters, which include consideration of amounts funded by Visa into its escrow account for the covered litigation matters. Changes, if any, in the valuation of this swap agreement, which has no determinable maturity date, are reflected in non-interest income.

Certain of TCF's forward foreign exchange contracts are not designated as hedges and are generally settled within 30 days. Changes in the fair value of these forward foreign exchange contracts are reflected in non-interest expense.

TCF enters into interest rate lock commitments in conjunction with certain consumer real estate loans. These interest rate lock commitments are agreements to extend credit under certain specified terms and conditions at fixed rates and have original lock expirations of up to 60 days. They are not designated as hedges and accordingly, changes in the valuation of these commitments are reflected in non-interest income.

The following tables summarize TCF's outstanding derivative instruments as of March 31, 2015 and December 31, 2014. See Note 13, Fair Value Disclosures, for additional information.

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 March 31, 2015, credit risk-related contingent features existed on forward foreign exchange contracts with a notional value of $138.0 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 $2.8 million in additional collateral. There were no forward foreign exchange contracts containing credit risk-related features in a net liability position at March 31, 2015.

At March 31, 2015, TCF had posted $11.1 million, $1.4 million and $1.1 million of cash collateral related to its interest rate contracts, other contracts and its forward foreign exchange contracts, respectively.

Loan Modifications for Borrowers with Financial Difficulties  Included within loans and leases in the previous tables 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. TDR loans consist primarily of consumer real estate and commercial loans.

Total TDR loans at March 31, 2015 and December 31, 2014 were $273.7 million and $298.5 million, respectively, of which $167.8 million and $193.8 million were accruing at March 31, 2015 and December 31, 2014, respectively. TCF held consumer real estate TDR loans of $198.7 million and $199.6 million at March 31, 2015 and December 31, 2014, respectively, of which $111.7 million and $111.9 million were accruing at March 31, 2015 and December 31, 2014, respectively. TCF also held $67.3 million and $91.6 million of commercial TDR loans at March 31, 2015 and December 31, 2014, respectively, of which $55.1 million and $80.4 million were accruing at March 31, 2015 and December 31, 2014, respectively. TDR loans for the remaining classes of finance receivables were not material at March 31, 2015 or December 31, 2014.

The amount of unfunded commitments to commercial and consumer real estate loans classified as TDRs was $3.8 million and $3.9 million at March 31, 2015 and December 31, 2014, respectively. At March 31, 2015 and December 31, 2014, no additional funds were committed to leasing and equipment finance, inventory finance or auto finance loans classified as TDRs.

When a loan is modified as a TDR, principal balances are generally not forgiven. Loan modifications to troubled borrowers are not reported as TDR loans in the calendar year after modification if the loans were modified at an interest rate equal to the yields of new loan originations with comparable risk and the loans are performing based on the terms of the restructured agreements. All loans classified as TDR loans are considered to be impaired. During the three months ended March 31, 2015 and 2014, $9.0 million and $11.1 million, respectively, of commercial loans were removed from TDR status as they were restructured at market terms and are performing.

The financial effects of TDR loans represent the difference between interest income recognized on accruing TDR loans and the contractual interest that would have been recorded under the original contractual terms, or foregone interest income. For the three months ended March 31, 2015, foregone interest income for 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 3.9%, which compares to the original contractual average rate of 6.5%. For the three months ended March 31, 2014, foregone interest income for consumer real estate first mortgage lien accruing TDR loans and consumer real estate junior lien accruing TDR loans was $4.4 million and $0.3 million, respectively. The average yield for the same period on consumer real estate accruing TDR loans was 3.2%, which compares to the original contractual average rate of 6.7%. The foregone interest income for the remaining classes of finance receivables was not material for the three months ended March 31, 2015 and 2014.

The table below summarizes TDR loans that defaulted during the three months ended March 31, 2015 and 2014, which were modified during the respective reporting period or within one year of the beginning of the respective reporting period. TCF considers a loan to have defaulted when it becomes 90 or more days delinquent under the modified terms, has been transferred to non-accrual status subsequent to the modification or has been transferred to other real estate owned or repossessed and returned assets.

(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 or the fair value of the collateral less selling expenses for collateral dependent loans. The allowance on accruing consumer real estate TDR loans was $20.3 million, or 18.2% of the outstanding balance, at March 31, 2015, and $20.4 million, or 18.2% of the outstanding balance, at December 31, 2014. In determining impairment for consumer real estate accruing TDR loans, TCF utilized assumed remaining re-default rates ranging from 6% to 20% in 2015 and 4% to 22% in 2014, depending on modification type and actual experience. At March 31, 2015, 2.3% of accruing consumer real estate TDR loans were more than 60 days delinquent, compared with 2.4% at December 31, 2014.

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 March 31, 2015, $52.4 million, or 60.2%, were loans discharged in Chapter 7 bankruptcy that were not reaffirmed, of which 71.1% were current. Of the non-accrual TDR balance at December 31, 2014, $50.0 million, or 57.0%, were loans discharged in Chapter 7 bankruptcy that were not reaffirmed, of which 68.4% 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, or for collateral dependent loans, at the fair value of collateral less selling expense. The allowance on accruing commercial TDR loans was $1.1 million, or 2.1% of the outstanding balance, at March 31, 2015, and $1.4 million, or 1.7% of the outstanding balance, at December 31, 2014. No accruing commercial TDR loans were 60 days or more delinquent at March 31, 2015 and December 31, 2014.

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. 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 tables, 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.

The following table summarizes impaired loans.

(1) Loans and leases are reported at historical cost including net direct fees and costs associated with originating and acquiring loans and leases, lease residuals, unearned income and unamortized purchase premiums and discounts. The aggregate amount of these loan and lease adjustments was $48.6 million and $43.4 million at March 31, 2015 and December 31, 2014, respectively.

The consumer real estate junior lien portfolio was comprised of $2.2 billion of home equity lines of credit ("HELOCs") and $404.9 million of amortizing junior lien mortgage loans at March 31, 2015, compared with $2.1 billion and $424.4 million at December 31, 2014, respectively. At March 31, 2015 and December 31, 2014, $1.4 billion and $1.3 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 March 31, 2015 and December 31, 2014, $778.2 million and $816.0 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 March 31, 2015, 18.2% of these loans mature prior to 2021.

During the three months ended March 31, 2015 and 2014, TCF sold $203.5 million and $261.7 million, respectively, of consumer auto loans with servicing retained, received cash of $210.5 million and $267.2 million, respectively, and recognized net gains of $6.7 million and $8.8 million, respectively. Related to these sales, TCF retained interest-only strips of $0 and $4.5 million for the three months ended March 31, 2015 and 2014, respectively. Total interest-only strips related to sales of auto loans totaled $41.1 million and $48.6 million at March 31, 2015 and December 31, 2014, respectively. TCF recorded impairment charges on these interest-only strips of $0.5 million and $1.2 million during the three months ended March 31, 2015 and 2014, respectively, primarily as a result of higher prepayments than originally assumed. Contractual recourse liabilities related to sales of auto loans totaled $0.4 million and $0.7 million at March 31, 2015 and December 31, 2014, respectively. No servicing assets or liabilities related to consumer auto 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's managed auto loan portfolio, which includes portfolio loans, loans held for sale and loans sold and serviced for others, totaled $4.2 billion and $3.8 billion at March 31, 2015 and December 31, 2014, respectively.

During the three months ended March 31, 2015 and 2014, TCF sold $264.3 million and $347.4 million, respectively, of consumer real estate loans, received cash of $271.0 million and $353.0 million, respectively, and recognized net gains of $8.2 million and $11.7 million, respectively. Related to these sales, TCF retained interest-only strips of $2.7 million and $8.2 million for the three months ended March 31, 2015 and 2014, respectively. Total interest-only strips related to sales of consumer real estate loans totaled $21.4 million and $21.2 million at March 31, 2015 and December 31, 2014, respectively. TCF had no impairment charges on these interest-only strips for the three months ended March 31, 2015 and 2014. Contractual recourse liabilities related to sales of consumer real estate loans totaled $0.6 million at both March 31, 2015 and December 31, 2014. No servicing assets or liabilities related to consumer real estate 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's managed consumer real estate loan portfolio, which includes portfolio loans, loans held for sale and loans sold and serviced for others, totaled $7.1 billion at both March 31, 2015 and December 31, 2014.

TCF's agreements to sell auto and consumer real estate loans typically contain certain representations and warranties regarding the loans sold. These representations and warranties 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, the loan's compliance with the criteria set forth in the agreement, payment delinquency and compliance with applicable laws and regulations. TCF may be required to repurchase loans in the event of an unremedied breach of these representations or warranties. During the three months ended March 31, 2015 and 2014, losses related to repurchases pursuant to such representations and warranties were immaterial. The majority of such repurchases were of consumer auto loans where TCF typically has contractual agreements with the automobile dealerships that originated the loans requiring the dealers to repurchase such contracts from TCF.

Litigation Contingencies

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 enforcement actions brought by federal regulators, including the Securities and Exchange Commission ("SEC"), the Federal Reserve, the OCC and the Consumer Financial Protection Bureau. 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. 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. TCF is also subject to regulatory examinations, and TCF's regulatory authorities may impose sanctions on TCF for failures related to regulatory compliance.

(1) Related to subordinated bank notes with a stated maturity of 2025 at March 31, 2015.

At March 31, 2015, TCF Bank had pledged loans secured by residential real estate, commercial real estate and Federal Home Loan Bank ("FHLB") stock with an aggregate carrying value of $4.9 billion as collateral for FHLB advances. At March 31, 2015, $350.0 million of FHLB advances outstanding were prepayable monthly at TCF's option.

On February 27, 2015, TCF Bank issued $150.0 million of subordinated notes due February 27, 2025 with a fixed-rate coupon of 4.60% per annum (the "2025 Notes"), at a price to investors of 99.375%. In addition, TCF Bank incurred issuance costs of $1.4 million. Both the discount and issuance costs are amortized to interest expense over the respective term of the notes using the effective interest method. Interest is payable semi-annually, in arrears, on February 27 and August 27, commencing August 27, 2015. Simultaneously, TCF Bank entered into an interest rate swap with a total notional amount of $150.0 million designated as a fair value hedge. The effect of the interest rate swap is to effectively convert the fixed-rate on the 2025 Notes to a floating interest rate based on the three-month London InterBank Offered Rate ("LIBOR") plus a fixed number of basis points on the $150.0 million notional amount. In exchange, TCF Bank will receive 4.60% fixed-rate interest based on the same notional amount from the swap counterparty. The gains and losses related to changes in the fair value of the interest rate swap are included in non-interest income in the Consolidated Statements of Income and substantially offset the change in the fair value of the hedged underlying debt that is attributable to the changes in market risk. The carrying value of the 2025 Notes was adjusted by an amount that is offset by the fair value of the interest rate swap. See Note 12 of Notes to Consolidated Financial Statements, Derivative Instruments, for additional information.

At March 31, 2015, all of the subordinated notes qualify as Tier 2 or supplementary capital for regulatory purposes, subject to certain regulatory limitations.

Regulatory Capital Requirements

Regulatory Capital Requirements [Abstract]

Regulatory Capital Requirements

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 profits for the current year combined with its net retained profits for the preceding two calendar years, which was $349.4 million at March 31, 2015, without prior approval of the Office of the Comptroller of the Currency ("OCC"). 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. These capital adequacy standards may be higher in the future than existing minimum regulatory capital requirements.

The following table presents regulatory capital information for TCF and TCF Bank. Information presented for March 31, 2015 reflects the transition to the Basel III capital standard from previous regulatory capital adequacy guidelines under the Basel I framework. The Basel III capital standard phases in through 2019 and revises the definition of capital, increases minimum capital ratios, introduces regulatory capital buffers above those minimums, introduces a common equity Tier 1 capital ratio and revises the rules for calculating risk-weighted assets. Banks that are not advanced approaches institutions may make a one-time election to opt out of the requirement to include components of accumulated other comprehensive income (loss) in common equity Tier 1 capital. TCF has elected to opt-out of the accumulated other comprehensive income (loss) requirement. The adoption of the new capital standard had an immaterial impact to TCF's capital levels and related ratios.

Earnings Per Share [Abstract]

Earnings Per Common Share

Earnings Per Common Share

TCF's restricted stock awards that pay non-forfeitable common stock dividends meet the criteria of a participating security. Accordingly, earnings per share is calculated using the two-class method, under which earnings are allocated to both common shares and participating securities.

	Three Months Ended   March 31,
(Dollars in thousands, except per-share data)	2015			2014

Diluted earnings per common share	$	0.21		$	0.24

All shares of restricted stock are deducted from weighted-average shares outstanding for the computation of basic earnings per common share. Shares of performance-based restricted stock are included in the calculation of diluted earnings per common share, using the treasury stock method, at the beginning of the quarter in which the performance goals have been achieved. All other shares of restricted stock, which vest over specified time periods, stock options and warrants are included in the calculation of diluted earnings per common share, using the treasury stock method.

For the three months ended March 31, 2015 and 2014, there were 4.4 million and 3.7 million, respectively, of outstanding shares related to non-participating restricted stock, stock options and warrants that were not included in the computation of diluted earnings per share because they were anti-dilutive.

There were no sales of securities available for sale during the three months ended March 31, 2015. Gross realized gains of $0.4 million were recognized on sales of securities available for sale during the three months ended March 31, 2014. At March 31, 2015 and December 31, 2014, mortgage-backed securities with a carrying value of $8.0 million and $8.2 million, respectively, were pledged as collateral to secure certain deposits and borrowings. There were no impairment charges recognized on securities available for sale during both the three months ended March 31, 2015 and 2014. Unrealized losses on securities available for sale are due to changes in interest rates. TCF has the ability and intent to hold these investments until a recovery of fair value occurs.

There were no transfers from available for sale mortgage-backed securities to held to maturity during the three months ended March 31, 2015. During the three months ended March 31, 2014, TCF transferred $191.7 million of available for sale mortgage-backed securities to held to maturity, reflecting TCF's intent and ability to hold these securities to maturity. At March 31, 2015 and December 31, 2014, the unrealized holding loss on the transferred securities retained in accumulated other comprehensive loss totaled $15.7 million and $16.0 million, respectively. These amounts are amortized over the remaining lives of the transferred securities. Other held to maturity securities consist primarily of non-trading mortgage-backed securities and other bonds which qualify for investment credit under the Community Reinvestment Act. During the three months ended March 31, 2015, TCF recorded an impairment charge of $0.1 million on held to maturity securities, which had a carrying value of $4.8 million. There were noimpairment charges recognized on held to maturity securities during the three months ended March 31, 2014.

The following tables show the gross unrealized losses and fair value of securities available for sale and securities held to maturity at March 31, 2015 and December 31, 2014, aggregated by investment category and the length of time the securities were in a continuous loss position.

Fair Values Disclosures

3 Months Ended

Fair Value Disclosures [Abstract]

Fair Value Disclosures

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 and leases held for sale, forward foreign exchange contracts, interest rate contracts, other contracts, interest rate lock commitments, forward loan sales commitments and assets and liabilities held in trust for deferred compensation plans 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, interest-only strips, other real estate owned and repossessed and returned assets. These non-recurring fair value adjustments typically involve application of lower-of-cost-or-market accounting or write-downs of individual assets.

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

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.

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 certain other securities held to maturity, categorized as Level 3, is estimated based on discounted cash flows using current market rates and consideration of credit exposure or other internal pricing methods. 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. The fair value of securities of U.S. Government sponsored enterprises and federal agencies, 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 and Leases Held for Sale Loans and leases held for sale are generally carried at the lower of cost or fair value. The cost of loans held for sale includes the unpaid principal balance, net of deferred loan fees and costs. Estimated fair values are based upon recent loan sale transactions and any available price quotes on loans with similar coupons, maturities and credit quality. Certain other loans and leases 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 and leases 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 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.

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, in accordance with GAAP, 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 swaps 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, such that TCF minimizes its net risk exposure resulting from such transactions. TCF also entered into an interest rate swap to convert its fixed-rate 2025 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.

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

Interest Rate Lock Commitments and Forward Loan Sales Commitments TCF's interest rate lock commitments are derivative instruments which 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 majority of the inputs significant in the valuation of these commitments fall within Level 3 and therefore they are categorized as Level 3.

Interest-Only StripsThe fair value of interest-only strips, categorized as Level 3, represents the present value of future cash flows retained 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.

Other Real Estate Owned and Repossessed and Returned Assets The fair value of other real estate owned 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 and repossessed and returned assets were written down $3.4 million and $3.3 million, which was included in foreclosed real estate and repossessed assets, net expense for the three months ended March 31, 2015 and 2014, respectively.

DepositsThe 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.

Long-term BorrowingsThe 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.

Assets and Liabilities Held in Trust for Deferred Compensation PlansAssets held in trust for deferred compensation plans include investments in publicly traded stocks, 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 upon prices obtained from independent asset pricing services based on active markets. The fair value of the liabilities equals the fair value of the assets.

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, as commitments and standby letters of credit similar to TCF's are not actively traded. 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.

The following tables present the balances of assets and liabilities measured at fair value on a recurring and non-recurring basis.

For purposes of this table, the derivative receivable and derivative payable balances 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 availability of 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 quarters ended March 31, 2015 and 2014.

The following table presents changes in Level 3 assets and liabilities measured at fair value on a recurring basis.

Fair Value Option

In the third quarter of 2014, TCF initiated a correspondent lending program in which TCF Bank originates consumer mortgage loans and sells them to a wholesale partner. 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 following table presents the difference between the aggregate fair value and aggregate unpaid principal balance of these loans held for sale.

(In thousands)	At March 31, 2015		At December 31, 2014
Fair value carrying amount	$	6,248	$	3,308
Aggregate unpaid principal amount	6,057		3,205
Fair value carrying amount less aggregate unpaid principal	$	191	$	103

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 nonaccrual status at March 31, 2015 or December 31, 2014. The net gain from initial measurement of the above loans and subsequent changes in fair value for loans outstanding was $1.5 million for the three months ended March 31, 2015, and is included in gains on sales of consumer real estate loans, net. This amount excludes the impact from offsetting hedging arrangements 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 March 31, 2015 and December 31, 2014, 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.

The following tables present 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. 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.
