	(1) Basis of Presentation
	TCF Financial Corporation, a Delaware corporation (“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.
	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, 2012, and for the year then ended. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior financial statements to conform to the current period presentation. For Consolidated Statements of Cash Flow purposes, cash and cash equivalents include cash and due from banks. Any policies in effect at December 31, 2012, remain unchanged and will be followed similarly as in previous periods, with the exception of the Company’s non-accrual policy which was amended during the third quarter of 2013, as noted below.
	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 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.
	Significant Accounting Policy Update
	In the third quarter of 2013, TCF modified its consumer real estate portfolio non-accrual policy. Under the new policy, consumer real estate loans are generally placed on non-accrual status once they become 90 days past due (previously 150 days past due) and charged off to the estimated fair value of underlying collateral, less estimated selling costs, no later than 150 days past due. In addition, consumer real estate junior lien loans are now placed on non-accrual status and charged off to the estimated fair value when the junior lien loan is 30 days or more past due and when TCF has evidence the related third-party first mortgage lien is 90 days or more past due or foreclosure action has been initiated.

	At September 30, 2013 and December 31, 2012, TCF Bank was required by Federal Reserve regulations to maintain reserves of $83.1 million and $79.7 million, respectively, in cash on hand or at the Federal Reserve.
	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 held in separate accounts until remitted. TCF also retains cash balances for potential loss recourse on certain sold auto loans as well as cash for collateral on certain borrowings and foreign exchange contracts. TCF maintained restricted cash totaling $52 million and $28.8 million at September 30, 2013 and December 31, 2012, respectively.

	There were no sales of securities available for sale during the first nine months of 2013. Gross realized gains on sales of securities available for sale of $13.2 million and $90.2 million were recognized during the third quarter and first nine months of 2012, respectively. Impairment charges of $206 thousand were recognized during the third quarter and first nine months of 2012.
	Unrealized losses on securities available for sale are due to lower values for equity securities or changes in interest rates. TCF has the ability and intent to hold these investments until a recovery of fair value occurs.
	The following table shows the gross unrealized losses and fair value of securities available for sale that are in a loss position at September 30, 2013 and December 31, 2012, aggregated by investment category and length of time the securities were in a continuous loss position.

	From time to time, TCF sells leasing and equipment finance loans and minimum lease payments to third-party financial institutions at fixed rates. For those transactions which achieve sale treatment, the related loan and lease cash flow stream is derecognized. During the three months ended September 30, 2013 and 2012, TCF sold $9.5 million and $16.8 million, respectively, of loans and minimum lease payment receivables, received cash of $9.6 million and $18.6 million, respectively, and recognized a net loss of $90 thousand and a net gain of $1.6 million, respectively. Related to these sales, TCF had servicing liabilities of $195 thousand and $231 thousand for the three months ended September 30, 2013 and 2012, respectively. During the nine months ended September 30, 2013 and 2012, TCF sold $43.4 million and $73.5 million, respectively, of loans and minimum lease payment receivables, received cash of $44.4 million and $76.1 million, respectively, and recognized a net loss of $44 thousand and a net gain of $1.9 million, respectively. Related to these sales, TCF had servicing liabilities of $963 thousand and $688 thousand for the nine months ended September 30, 2013 and 2012, respectively.

Related to these sales, TCF retained interest-only strips of $13.7 million and $12.6 million for the three months ended September 30, 2013 and 2012, respectively. During the nine months ended September 30, 2013 and 2012, TCF sold $559.3 million and $377.1 million, respectively, of consumer auto loans and servicing retained with limited representations and indemnifications, received cash of $544.2 million and $368.9 million, respectively, and recognized net gains of $22.4 million and $15.2 million, respectively. Related to these sales, TCF retained interest-only strips of $42.2 million and $27.3 million for the nine months ended September 30, 2013 and 2012, respectively. At September 30, 2013, interest-only strips and contractual recourse liabilities related to sales of auto loans totaled $64.8 million and $1.6 million, respectively. At December 31, 2012, interest-only strips and contractual recourse liabilities related to sales of auto loans totaled $46.7 million and $3.6 million, respectively. TCF recorded impairment charges related to auto finance interest-only strips of $3.4 million and $5.2 million during the three and nine months ended September 30, 2013, respectively, and $286 thousand for both the three and nine months ended September 30, 2012. These impairments were related to higher prepayments than originally assumed. 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. TCF’s auto loan managed portfolio, which includes portfolio loans, loans held for sale, and loans sold and serviced for others, totaled $2.1 billion and $1.3 billion at September 30, 2013 and December 31, 2012, respectively.
	During the three months ended September 30, 2013 and 2012, TCF sold $142.4 million and $136 million, respectively, of consumer real estate loans, with limited representations and indemnifications, received cash of $142.4 million and $141.4 million, respectively, and recognized net gains of $4.2 million and $4.6 million, respectively. Related to these sales, TCF retained interest-only strips of $4.8 million and $0 for the three months ended September 30, 2013 and 2012, respectively. During the nine months ended September 30, 2013 and 2012, TCF sold $560.8 million and $136 million, respectively, of consumer real estate loans, with limited representations, indemnifications, and limited credit guarantees, received cash of $564.1 million and $141.4 million, respectively, and recognized net gains of $16.3 million and $4.6 million, respectively. Related to these sales, TCF retained interest-only strips of $16.4 million and $0 for the nine months ended September 30, 2013 and 2012, respectively. At September 30, 2013, interest-only strips and contractual recourse liabilities related to sales of consumer real estate loans totaled $15.3 million and $563 thousand, respectively. TCF recorded impairment charges related to consumer real estate interest-only strips of $0 and $466 thousand during the three and nine months ended September 30, 2013, respectively, and no impairment charge for the same periods in 2012. 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. TCF’s consumer real estate loan managed portfolio, which includes portfolio loans, loans held for sale, and loans sold and serviced for others, totaled $6.9 billion and $6.7 billion at September 30, 2013 and December 31, 2012, respectively.
	TCF’s agreements to sell consumer real estate and auto 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 nine months ended September 30, 2013 and 2012, losses related to repurchases pursuant to such representations and warranties were immaterial as the majority of such repurchases were of consumer auto loans where TCF typically has contractual agreements with the automobile dealership that originated the loan requiring the dealer to repurchase such contracts from TCF.

Accruing and Non-accrual Loans and Leases  The following tables set forth information regarding TCF’s accruing and non-accrual loans and leases. Non-accrual loans and leases are those which management believes have a higher risk of loss than accruing loans and leases. Delinquent balances are determined based on the contractual terms of the loan or lease. TCF’s key credit quality indicator is the receivable’s payment performance status as accruing or non-accruing. TCF modified its consumer real estate portfolio non-accrual policy in the third quarter of 2013. See Note 1 of Notes to the Consolidated Financial Statements, Basis of Presentation, for additional information.

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”).
The following tables provide a summary of accruing and non-accrual TDR loans by portfolio.

The amount of additional funds committed to consumer real estate and commercial borrowers in TDR status was $3.5 million and $8.6 million at September 30, 2013 and December 31, 2012, respectively. At September 30, 2013 and December 31, 2012, no additional funds were committed to leasing and equipment finance, inventory finance or auto finance borrowers in TDR status.
When a loan is modified as a TDR, principal balances are generally not forgiven. Loan modifications are not reported as TDR loans in calendar years 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 restructuring agreements. All loans classified as TDR loans are considered to be impaired. During the nine months ended September 30, 2013, $17.1 million of commercial loans were removed from TDR status as they were restructured at market terms and are performing.
The financial effects of TDR loans are presented in the following tables and 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.

The table below summarizes TDR loans that defaulted during the three and nine months ended September 30, 2013 and 2012, which were modified 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.

(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 $104.2 million, or 20.3% of the outstanding balance, at September 30, 2013, and $82.3 million, or 17.2% of the outstanding balance, at December 31, 2012. For consumer real estate TDR loans, TCF utilized average remaining re-default rates ranging from 11% to 25% in 2013, compared with 10% to 25% in 2012, depending on modification type, in determining impairment, which is consistent with actual experience. Generally consumer real estate loans remain on accruing status upon modification if they are less than 90 days past due and payment in full under the modified loan terms is expected. In addition, consumer real estate junior lien loans are placed on non-accrual status and charged off to the estimated fair value when the junior lien loan is 30 days or more past due and when TCF has evidence that the related third-party first mortgage lien is 90 days or more past due or foreclosure action has been initiated. Loans are placed on non-accrual status and reported as non-accrual until there is sustained repayment performance for six consecutive payments, except for loans discharged in Chapter 7 bankruptcy that are not reaffirmed, which remain on non-accrual status for the remainder of the term of the loan. 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 the fair value of the collateral less selling expenses for collateral-dependent loans. The allowance on accruing commercial TDR loans was $3 million, or 2.4% of the outstanding balance, at September 30, 2013, and $1.5 million, or 1% of the outstanding balance, at December 31, 2012.
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. Non-accrual commercial loans are charged off to the estimated fair value of underlying collateral, less estimated selling costs. 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 tables summarize impaired loans.

	At September 30, 2013, TCF Bank had pledged loans secured by residential real estate and commercial real estate loans with an aggregate carrying value of $5.2 billion as collateral for Federal Home Loan Bank (“FHLB”) advances. There were no callable advances included in FHLB borrowings at September 30, 2013 or December 31, 2012.
	On June 17, 2013, TCF Bank redeemed at par $71 million aggregate outstanding balance of its subordinated notes due 2014. There were no remaining discounts or deferred fees associated with the notes and, as a result, there was no gain or loss associated with the redemption. Effective June 15, 2013, the subordinated notes due 2014 no longer qualified for treatment as Tier 2 or supplementary capital.
	The $50 million of subordinated notes due 2015 re-price quarterly at the three-month LIBOR rate plus 1.56%. These subordinated notes may be redeemed by TCF Bank at par once per quarter at TCF Bank’s discretion. The $74.9 million of subordinated notes due 2016 have a fixed-rate coupon of 5.5% per annum until maturity. The $109.1 million of subordinated notes due 2022 have a fixed-rate coupon of 6.25% per annum until maturity. At September 30, 2013, all of the subordinated notes qualify as Tier 2 or supplementary capital for regulatory purposes, subject to certain regulatory limitations.
	On August 5, 2013, TCF Bank terminated $50 million long-term variable rate FHLB advances scheduled to mature on January 3, 2014, resulting in a loss on termination of $55 thousand.

	(8)  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 Corporation in excess of 100% of its net retained profits for the current year combined with its retained net profits for the preceding two calendar years, which was a negative $18.5 million at September 30, 2013, 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.

Derivative Instruments	'
Derivative Instruments	'
	(11)  Derivative Instruments
	All derivative instruments are recognized within other assets or other liabilities at fair value within the Consolidated Statements of Financial Condition. These contracts typically settle within 30 days, with the exception of a swap agreement, which has no determinable maturity date.
	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 cash flows 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 a forecasted transaction or the variability of cash flows to be paid related to a recognized asset or liability (“cash flow hedge”), a hedge of the volatility of an investment in foreign operations driven by changes in foreign currency exchange rates (“net investment hedge”), or is not designated as a hedge. To the extent that an instrument is designated as an effective hedge, changes in fair value are recorded within accumulated other comprehensive income (loss), with any ineffectiveness recorded in non-interest expense. Amounts recorded within other comprehensive income (loss) are subsequently reclassified to non-interest expense upon completion of the related transaction. 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 ceased and any gain or loss included in other comprehensive income (loss) is reported in earnings immediately.
	Cash Flow Hedges  TCF uses forward foreign exchange contracts to manage the foreign exchange risk associated with certain assets, liabilities and forecasted transactions. Forward foreign exchange contracts represent agreements to exchange a foreign currency for U.S. dollars at an agreed-upon price and settlement date.
	Net Investment Hedges  Foreign exchange contracts, which include forward contracts and currency options, 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, along with certain assets, liabilities and forecasted transactions of that subsidiary.
	Derivatives Not Designated as Hedges  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 will 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 in the valuation of this swap agreement are reflected in non-interest income.  Additionally, certain forward foreign exchange contracts used to manage foreign exchange risk are not designated as hedges.  Changes in the fair value of these foreign exchange contracts are reflected in non-interest expense.
	The following tables summarize TCF’s outstanding derivative instruments as of September 30, 2013 and December 31, 2012. See Note 12, Fair Value Measurement for additional information.

	TCF executes all of its foreign exchange contracts in the over-the-counter market with large, international financial institutions pursuant to International Swaps and Derivatives Association, Inc. master 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.
	In connection with certain over-the-counter forward foreign exchange contracts, TCF could be required to terminate transactions with certain counterparties in the event that, among other things, TCF Bank’s long-term debt is rated less than BBB- by Standard and Poor’s or Baa3 by Moody’s. At September 30, 2013, credit risk-related contingent features existed on forward foreign exchange contracts with a notional value of $145.5 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 $2.9 million in additional collateral.
	At September 30, 2013, TCF posted $4 million and $1.4 million of cash collateral related to its forward foreign exchange contracts and swap agreement, respectively.

Fair Value Measurement	'
Fair Value Measurement	'
	(12)  Fair Value Measurement
	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, derivatives (forward foreign exchange contracts and swaps), and assets held in trust for deferred compensation plans are recorded at fair value on a recurring basis.  Certain investments, commercial loans, real estate owned, repossessed and returned assets and certain interest-only strips are recorded at fair value on a non-recurring basis.
	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 instruments traded in active markets; Level 2, which includes valuations that are based on prices obtained from independent pricing sources that are based on observable transactions of similar instruments, but not quoted markets; and Level 3, for which valuations are generated from Company model-based techniques that use significant unobservable inputs. Such unobservable inputs reflect estimates of assumptions that market participants would use in pricing the asset or liability.
	The following tables present the balances of assets and liabilities measured at fair value on a recurring and non-recurring basis.

	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 and/or economic conditions, as well as to Company valuation models may require the transfer of financial instruments from one fair value level to another. Such transfers, if any, represent the fair values as of the beginning of the quarter in which the transfer occurred.  As a result of the adoption of Financial Accounting Standards Board (“FASB”) guidance in the first quarter of 2012, TCF transferred $1.1 million of securities from Level 3 to Level 1 in the nine months ended September 30, 2012.

The following is a description of valuation methodologies used for assets and liabilities recorded at fair value on a recurring basis.
Securities Available for Sale Securities available for sale consist primarily of U.S. Government sponsored enterprise and federal agency securities. The fair value of U.S. Government sponsored enterprise securities is recorded using prices obtained from independent asset pricing services that are based on observable transactions, but not quoted markets, and are categorized as Level 2 assets.  Management reviews the prices obtained from independent asset pricing services for unusual fluctuations and comparisons to current market trading activity. Other mortgage-backed securities, for which there is little or no market activity, are categorized as Level 3 assets and the fair value of these assets is determined by using internal pricing methods. Other securities are categorized as Level 1 assets and the fair value is determined using quoted prices from the New York Stock Exchange.
Forward Foreign Exchange Contracts TCF’s forward foreign exchange contracts are currency contracts executed in over-the-counter markets and are valued 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 majority of these contracts are based on observable transactions, but not quoted markets, and are categorized as Level 2 assets and liabilities. As permitted under GAAP, TCF has elected to net derivative receivables and derivative payables and the related cash collateral received and paid, when a legally enforceable master netting agreement exists. For purposes of the previous tables, the derivative receivable and payable balances are presented gross of this netting adjustment.
Swap Agreement TCF’s swap agreement relates to the sale of TCF’s Visa Class B stock, and is categorized as a Level 3 liability.  The value of the swap 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.  As permitted under GAAP, TCF has elected to net derivative receivables and derivative payables and the related cash collateral received and paid, when a legally enforceable master netting agreement exists. For purposes of the previous tables, the derivative receivable and payable balances are presented gross of this netting adjustment.
Assets Held in Trust for Deferred Compensation 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 is based upon prices obtained from independent asset pricing services based on active markets.
The following is a description of valuation methodologies used for assets measured on a non-recurring basis.
Loans Impaired loans for which repayment of the loan is expected to be provided solely by the value of the underlying collateral are considered collateral dependent and are valued based on the fair value of such collateral, less estimated recovery and selling costs.  Selling costs are generally 10% of the fair value of the underlying collateral.
Other Real Estate Owned and Repossessed and Returned Assets  The fair value of real estate owned is based on independent full appraisals, real estate broker’s price opinions, or automated valuation methods, less estimated selling costs.  Selling costs are generally 10% of the fair value of the underlying collateral.  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 real estate owned or repossessed and returned assets.  Other real estate owned and repossessed and returned assets were written down $2.2 million and $12 million, which was included in foreclosed real estate and repossessed assets, net expense for the three and nine months ended September 30, 2013, respectively.
Interest-Only Strips  The fair value of interest-only strips 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 the Company 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 strip may fluctuate significantly from period to period.
Investments The fair value of investments is estimated based on discounted cash flows using current market rates and consideration of credit exposure.  There is not an observable secondary market for these securities.

	(13)  Fair Value of Financial Instruments
	Management discloses the estimated fair value of financial instruments, both assets and liabilities on and off the balance sheet, for which it is practicable to estimate fair value. These fair value estimates were made at September 30, 2013 and December 31, 2012, 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 carrying amounts and estimated fair values of the Company’s financial instruments are set forth in the following table. 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.

	(1)  Contracts are carried at fair value, net of the related cash collateral received and paid when a legally enforceable master netting agreement exists.
	(2)  Carrying amounts are included in other assets.
	(3)  Expected credit losses are included in the estimated fair values.
	(4)  Positive amounts represent assets, negative amounts represent liabilities.
	(5)  Carrying amounts are included in accrued expenses and other liabilities.
	The carrying amounts of cash and due from banks and accrued interest payable and receivable approximate their fair values due to the short period of time until their expected realization.  Securities available for sale, forward foreign exchange contracts and assets held in trust for deferred compensation plans are carried at fair value (see Note 12, Fair Value Measurement).  Certain financial instruments, including lease financings and all non-financial instruments are excluded from fair value of financial instrument disclosure requirements.  The following methods and assumptions are used by TCF in estimating fair value for its remaining financial instruments, all of which are issued or held for purposes other than trading.
	Investments The carrying value of investments in FHLB stock and Federal Reserve stock approximates fair value.  The fair value of other investments is estimated based on discounted cash flows using current market rates and consideration of credit exposure.
	Loans and Leases Held for Sale  Loans and leases held for sale are carried at the lower of cost or fair value.  The cost of loans held for sale includes the unpaid principal balance, net of deferred loans 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.
	Loans The fair value of loans 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.
	Deposits The fair value of checking, savings and money market deposits is deemed equal to the amount payable on demand.  The fair value of certificates of deposit 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.
	Borrowings The carrying amounts of short-term borrowings approximate their fair values.  The fair values of TCF’s long-term borrowings are estimated based on observable market prices and discounted cash flows using interest rates for borrowings of similar remaining maturities and characteristics.
	Financial Instruments with Off-Balance Sheet Risk The fair values of TCF’s commitments to extend credit and standby letters of credit are 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.
	Interest-Only Strips The fair value of each pool of interest-only strips is estimated based on prepayment rates in accordance with historical experience and other assumptions, such as discount rates, weighted average remaining term and weighted average estimated cumulative loss rate.

	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 these 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 is currently subject to a Consent Order with the OCC relating to its Bank Secrecy Act of 1970 compliance.
