Our Strategies in Motion TCF Financial Corporation 2017 annual report OUR STRATEGIES IN MOTION Introduced in 2015, TCF’s four strategic pillars represent the basis for its business model and strategic decision making processes. The pillars are built on a strong enterprise risk management and credit culture. Execution against these four pillars is critical to ensure the creation of superior and sustainable financial performance moving forward.

Dahl, Chairman and Chief Executive Officer Throughout 2017, TCF continued to build on its “One TCF” culture that encourages collaboration and efficiencies across the organization. With the execution of several key initiatives in 2017 and strategies in motion for the future, TCF is building momentum as One TCF. Dear Shareholders: Throughout my first two years as CEO, I have spoken extensively about focusing on our “One TCF” culture to improve the returns to our shareholders. During these two years, our team has worked very hard to deliver on this goal. As a result, TCF continued to generate positive momentum throughout 2017 that positions us to be successful in 2018. I believe we will look back at 2017 as an inflection point for our organization that will result in the superior and sustainable long-term results we are focused on achieving. In 2017, we continued to execute on our four strategic pillars: 1) diversification, 2) profitable growth, 3) operating leverage and 4) core funding. I remain committed to these pillars as they are the foundation for all that we do. The business philosophies we have in place, coupled with several key actions throughout the year, resulted in improved core earnings trends. We have also continued to invest in talent and technology, both of which are playing a key role in moving the organization forward. I sense a more positive sentiment around the organization, both internally and externally, which has me excited about what lies ahead. Building momentum in 2017 TCF had a transformational year in 2017, with the most significant action being the discontinuation of our auto finance loan originations effective December 1, 2017. While it had been a contributor to loan and lease growth over the past several years, we determined that the financial outlook of the auto finance business was less favorable compared to alternative uses of capital. We believe we can earn a higher return by investing in other initiatives such as organic loan and lease growth, dividend increases, stock repurchases, corporate development and investments in our business. We recognized the auto finance business was a key headwind for the stock and believe the additional capital flexibility will be a benefit for our shareholders moving forward. We also received an estimated net tax benefit of $130.7 million from the Tax Cuts and Jobs Act (“Tax Reform”) enacted in late 2017, resulting from the re-measurement of our estimated net deferred tax liability, primarily generated from accelerated tax depreciation on our leasing portfolio. In addition, we expect Tax Reform to result in a significantly lower effective tax rate of approximately 1 23 percent to 25 percent beginning in 2018. As a result of these benefits, we were pleased to provide approximately $4.6 million in one-time bonuses to eligible team members. In addition, we donated $5.0 million to the TCF Foundation that will increase the grants we provide to nonprofit organizations in the communities we serve. Optimizing our capital remains a key opportunity for us to deliver value to our shareholders. We began doing this through several actions in 2017. First, we completed various portfolio purchases and acquired two businesses that have supported our focus on profitable growth. Second, we proactively refinanced our 7.50% Series A non- cumulative perpetual preferred stock with 5.70% Series C non-cumulative perpetual preferred stock, resulting in annual savings of approximately $3.0 million beginning in 2018. Finally, as part of our discontinuation of auto finance loan originations, we launched a new share repurchase program of $150.0 million and began repurchasing common stock in the fourth quarter. We also took steps in 2017 to further reduce the risk profile of our balance sheet as non-accrual loans and leases decreased by 34.6 percent and other real estate owned decreased by 61.1 percent from December 31, 2016. The run-off of our auto finance portfolio will also have a positive impact on our overall risk profile over time. A key win for TCF in 2017 was the successful launch of our new digital banking platform. We invested heavily in this initiative to ensure our customers have the tools and resources that meet their evolving financial needs. The new digital platform includes mobile deposit, fingerprint identification, enhanced planning tools and much more. In addition, the new platform will allow us to more efficiently add on new features in the future. Our ability to offer a competitive digital product to our customers is critical for the future of the organization. As we executed on these initiatives, as well as our core business strategies, we did so under the lens of our four strategic pillars. This means we understand the significance of a well-diversified balance sheet funded by a low-cost, core deposit base. It also means we understand the importance of growing the balance sheet in a way that can optimize the profitability of the organization as a whole. Finally, it means improving efficiencies within the organization is a guiding factor in the decisions we make. Diversification Maintaining a well-diversified loan and lease portfolio is one of our core business philosophies. Not only do we have multiple asset classes within our loan and lease portfolio, each asset class is further diversified by geography, rate, average loan and lease size, estimated weighted average life and collateral type. Importantly, we are able to compete as experts within each segment in which we participate. Our strong diversification provides the flexibility to be selective in where and how we grow based on changing appetites or market factors. For example, we discontinued auto finance loan originations as we felt there were better places to invest our capital to improve our overall returns. We were able to do this because of our diversified portfolio and our opportunities for growth in other areas, including our investment portfolio. From an earnings asset growth standpoint, we can be thoughtful when considering how to redeploy the run-off of the auto finance portfolio to optimize our return on capital. The value of our loan and lease diversification has also been demonstrated through our stable credit quality in 2017 compared to 2016, with steady delinquencies and net charge-offs and lower non-performing assets. While we saw an increase in auto finance net charge-offs in 2017, this was more than offset by an improvement in consumer real estate. Profitable growth TCF grew loans and leases by 7.1 percent in 2017 driven by strong growth in our wholesale businesses. While we were pleased with this level of growth, our focus remains on optimizing the level of profitability. We are not interested in growth just for the sake of growth. In addition, we took steps in 2017 to improve our earnings predictability by reducing our reliance on gains on sales of loans and increasing our net interest income. A key factor in our profitability was our net interest income which increased 9.1 percent in 2017. We continue to have one of the highest net interest margins in the industry, which has further benefited from the recent interest rate hikes. Loan and lease yields in 2017 increased 33 basis points primarily due to increases in short-term rates, our strategy of competing as experts in niche segments and our pricing discipline, while deposit costs remained well-managed with an increase of just two basis points. 2 2017 WILLIAM A. COOPER INNOVATION AWARD A team of business and IT leaders was recognized with the 2017 William A. Cooper Innovation Award for their work in creating and successfully launching a new digital banking platform. This award recognizes significant advancement of products, processes, services, technologies, or ideas that enable TCF to enhance its ability to serve its customers. In 2017, we completed a strategic leasing company acquisition, a $445.5 million leasing and equipment finance portfolio purchase and an acquisition of a residential mortgage lending business, all of which support our pillar of profitable growth. The leasing company acquisition resulted in increased leasing and equipment finance non- interest income while the portfolio purchase resulted in loan and lease growth with strong yields. The mortgage lending business acquisition provides a first mortgage loan origination platform that will create incremental gains on sales revenue and the potential for future loan growth if we choose to hold the loans on our balance sheet. Going forward, we expect to focus on organic growth opportunities, but we will continue to pursue acquisition opportunities that fit our risk-reward profile. Our decision to discontinue auto finance originations further demonstrates our commitment to profitable growth. By making this decision, we chose profitability over growth. Even with the potential for reduced loan and lease growth, we expect to be more profitable in 2018 by putting funds from the auto finance run-off to work in other capacities. We are committed to generating profitable growth that leads to higher returns on our capital. Operating leverage I have made it a priority during my first two years as CEO to focus on improving the efficiency of our organization by increasing revenues more than expenses. We recognize a bank’s efficiency ratio has a high correlation to valuation. In 2017, our efficiency ratio was significantly impacted by the strategic changes made to our auto finance business. In addition, we continued making key investments in technology across the organization. As a result of our actions in 2017, I believe we are now in a position where we can show meaningful improvement in our efficiency ratio. At TCF, we have a business model that generates revenue well in excess of our similarly sized peers. Our challenge is to do this more efficiently. We expect to execute on this in 2018 as a result of various efficiency initiatives, including the discontinuation of auto finance loan originations. I believe improving the efficiency with which we operate is a significant opportunity for us to improve the returns to our shareholders. We have instilled a culture in our organization that the decisions we make should be made with an eye toward the long-term impact they will have on our operating leverage. While balancing this culture with continued investments in our businesses, we feel we are in a good position to take meaningful steps toward becoming a more efficient organization in 2018. Core funding The primary funding source of our loans and leases is our low-cost deposit base, which totaled $18.3 billion at December 31, 2017, a 6.3 percent increase from December 31, 2016. This granular deposit base is a very valuable part of our franchise. As short-term rates have increased, the relative value of the deposit base has been evident in our well-managed deposit costs. Deposit costs in 2017 were 0.38 percent, an increase of just two basis points compared to 2016, despite the steady increase in interest rates and growth in the deposit base. Our ability to continue to grow core checking balances is directly tied to the convenience we provide to our retail customers. The definition of “convenience” has evolved and now places more emphasis on 24/7 banking through digital channels as opposed to the number of branches and branch hours. Since the launch of our new digital banking platform in 2017, we have been pleased with the significant increases in usage by our customers. This tells us the solutions we are providing are meeting their needs. 3 Although we continue to be subject to the Consumer Financial Protection Bureau’s (CFPB) lawsuit regarding our overdraft opt-in practices, we received a favorable ruling from the court in September 2017 related to our motion to dismiss. We remain confident that the way we provided our overdraft program to our customers complied with all applicable laws and regulations and we treated our customers fairly. We believe the facts and the law will support our legal position. Another key driver of our success moving forward will be our people. Our people are our most important resource. We are investing heavily in the development and retention of our team members. We are also focused on attracting team members who demonstrate leadership and expertise in areas that are important to our future success. The hard work of all our team members, including our board of directors and executive management team, has been vital to our success over the past year. I thank them all for their efforts. I am very excited about the positive momentum we have generated in 2017 and what it can mean for our organization in 2018 and beyond. This momentum gives us the opportunity to focus on making investments in our future and improving returns for shareholders through various channels. This is important to our shareholders and it is important to the board of directors and executive management team at TCF. We have strategies in motion to generate the returns our shareholders expect. By working together as “One TCF”, we can continue to build momentum and deliver the results needed to achieve our goals. We made many tough decisions in 2017 that have set the stage for what is to come. The work is not done, but I believe we have an organization that is built for the future and a focus that aligns with the goals of our shareholders. Craig R. Dahl Chairman and Chief Executive Officer We believe the new platform will help retain existing customers and attract new customers to TCF. Looking ahead, we expect to continue to generate core deposit growth while retaining our access to wholesale funding sources, which can be used as needed based on anticipated loan and lease growth. We also believe our deposit composition will allow us to effectively manage deposit costs moving forward, especially given the additional funding generated by the run-off of our auto finance portfolio. I view our deposit base as the strength of our franchise. Positioned for success in 2018 As you can see, we demonstrated real momentum in 2017 that we believe has positioned us to be successful in 2018. We have an auto finance run-off headwind we expect to not only eliminate, but turn into a tailwind as we improve our risk profile and redeploy the capital into higher return initiatives. We are continuing to see opportunities for growth in our wholesale loan and lease portfolios. As a bank with an asset sensitive balance sheet, we expect to continue to benefit from anticipated additional interest rate hikes in 2018, both from disciplined loan and lease pricing and a preferred deposit composition. In addition, there are opportunities for us to start making meaningful progress in lowering our efficiency ratio. Perhaps what I am most encouraged by is our opportunity to be more proactive in deploying excess capital that has been generated by earnings accumulation and tax reform. In fact, this has already begun. In early 2018 we announced a quarterly common stock dividend of 15 cents per share, an increase of 100 percent compared to our previous quarterly cash dividend. In addition, we announced we will be redeeming the Series B non- cumulative perpetual preferred stock on March 1, 2018. We expect this to result in an annual after-tax expense savings of $6.5 million beginning in the second quarter of 2018. For the past two years, I have indicated that we have been reviewing four potential uses of capital including organic loan and lease growth, dividend increases, stock repurchases, and corporate development. As of early 2018, we have now deployed capital into all of these areas. Going forward, we will continue to evaluate these channels, as well as investments in our business, for additional deployment of excess capital. We understand that deploying capital is important to our shareholders and I believe we have positioned ourselves to do so effectively. 4 FORM 10-K For the fiscal year ended December 31, 2017 3 UNITED STATES SECURITIES AND EXCHANGE COMMISSION WASHINGTON, D.C. 20549 FORM 10-K þ ANNUAL REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 For the fiscal year ended December 31, 2017  or ¨ Transition Report Pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 For the transition period from to  Commission File No. 001-10253 TCF Financial Corporation (Exact name of registrant as specified in its charter) (State or other jurisdiction of incorporation or organization) (I.R.S.

Business General TCF Financial Corporation (together with its direct and indirect subsidiaries, "we," "us," "our," "TCF" or the "Company"), a Delaware corporation incorporated on April 28, 1987, is a national bank holding company based in Wayzata, Minnesota. References herein to "TCF Financial" or the "Holding Company" refer to TCF Financial Corporation on an unconsolidated basis. TCF's principal subsidiary, TCF National Bank ("TCF Bank"), is headquartered in Sioux Falls, South Dakota. TCF Bank operates bank branches in Illinois, Minnesota, Michigan, Colorado, Wisconsin, Arizona and South Dakota (TCF's primary banking markets). TCF delivers consumer banking services in 46 states and commercial banking services in 34 states. TCF also conducts commercial leasing and equipment finance business in all 50 states and, to a limited extent, in foreign countries and commercial inventory finance business in all 50 states and Canada and, to a limited extent, in other foreign countries. Effective April 1, 2017, the Company executed its strategic shift from an originate-to-sell and originate-to-hold model to an entirely originate-to-hold model for its auto finance business and effective December 1, 2017, the Company discontinued auto finance loan originations. The determination was based on management's review of strategic alternatives and the financial outlook of the auto finance loan origination business compared with alternative uses of capital. TCF's subsidiary, Gateway One Lending & Finance, LLC ("Gateway One"), will continue to service existing auto loans on its balance sheet and those serviced for others. The decision to discontinue auto finance loan originations resulted in a goodwill impairment charge of $73.0 million, an other intangible assets impairment charge of $0.4 million and approximately $14.8 million of expenses related to severance, other asset impairments and lease termination expenses in 2017. TCF generated total revenue, defined as net interest income plus total non-interest income, of $1.4 billion, $1.3 billion and $1.2 billion in the United States in 2017, 2016 and 2015, respectively. International revenue, primarily from Canada, was $22.6 million, $25.6 million and $27.3 million in 2017, 2016 and 2015, respectively. TCF had total assets of $23.0 billion as of December 31, 2017 and was the 46th largest publicly traded bank holding company in the United States based on total assets at September 30, 2017. TCF provides convenient financial services through multiple channels in its primary banking markets. TCF has developed products and services designed to meet the specific needs of the largest consumer segments in the market. The Company focuses on attracting and retaining customers through service and convenience, including select locations open seven days a week with extended hours and on most holidays, full-service supermarket branches, access to automated teller machine ("ATM") networks and digital banking channels. TCF's philosophy is to generate interest income, fees and other revenue growth through business lines that emphasize higher yielding assets and low interest cost deposits. TCF's growth strategies include organic growth in existing businesses, development of new products and services, new customer acquisition and acquisitions of portfolios or businesses. New products and services are designed to build on existing businesses and expand into complementary products and services through strategic initiatives. Funded generally through retail deposit generation, TCF continues to focus on profitable asset growth. The Company's reportable segments are Consumer Banking, Wholesale Banking and Enterprise Services. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations ("Management's Discussion and Analysis") - Results of Operations - Reportable Segment Results" and Note 24. Business Segments of Notes to Consolidated Financial Statements for information regarding net income (loss), assets and revenues for each of TCF's reportable segments. 1 Consumer Banking Consumer Banking is comprised of all of the Company's consumer-facing businesses and includes retail banking, consumer real estate and auto finance. TCF's consumer banking strategy is primarily to originate high credit quality secured consumer real estate loans for investment and for sale and to generate deposits. Effective April 1, 2017, the Company executed its strategic shift from an originate-to-sell and originate-to-hold model to an entirely originate-to- hold model for its auto finance business and effective December 1, 2017, the Company discontinued auto finance loan originations. Deposits are generated from consumers and small businesses to provide a source of low cost funds, with a focus on building and maintaining quality customer relationships. The Consumer Banking reportable segment generates a significant portion of the Company's net interest income and non-interest income from fees and service charges, card revenue, ATM revenue, gains on sales of loans and servicing fee income, and incurs a significant portion of the Company's provision for credit losses and non-interest expense. Retail Banking TCF offers an array of solutions for consumers and small businesses through its physical and digital distribution channels. TCF offers a broad selection of deposit and lending services including (i) checking and savings accounts, (ii) credit, debit and prepaid cards, (iii) check cashing and remittance services and (iv) residential, consumer and small business lending. Deposits are a primary source of TCF's funds for use in lending and for other general business purposes. Deposit inflows and outflows are significantly influenced by general interest rates, market and competitive conditions and other economic factors. Deposits are acquired from within TCF's primary banking markets through (i) checking, savings and money market accounts, (ii) certificates of deposit and (iii) individual retirement accounts. Such deposit accounts provide fee income, including banking fees and service charges. Checking, savings and certain money market accounts are a source of low cost or no cost funds. At December 31, 2017, TCF had 320 branches, consisting of 189 traditional branches, 128 supermarket branches and three campus branches. TCF operates 123 branches in Illinois, 88 in Minnesota, 50 in Michigan, 33 in Colorado, 17 in Wisconsin, seven in Arizona and two in South Dakota. TCF currently plans to close five supermarket branches in early 2018, of which three are in Illinois and two are in Minnesota. TCF also offers 836 ATMs across TCF's primary banking markets. See "Item 1A. Risk Factors" for further information regarding the risks related to TCF's supermarket branch relationships. Non-interest income is a significant source of revenue for TCF and an important component of TCF's results of operations. Providing a wide range of retail banking services is an integral component of TCF's business philosophy. Primary drivers of bank fees and service charges include the number of customers we attract, the customers' level of engagement and the frequency with which the customer uses our solutions. TCF's business philosophy is to offer our customers an "easy-to-bank-with" experience, with multiple solutions that benefit the customer and are consistent with TCF's business philosophy. Customers have convenient access to their funds through their credit, debit and prepaid cards, as well as by utilizing TCF's enhanced digital channels. TCF's card programs are supported by interchange fees paid by retailers. Consumer Real Estate TCF originates consumer loans for personal, family or household purposes, such as home purchases, debt consolidation and financing of home improvements. TCF's retail lending origination activity primarily consists of consumer real estate secured lending. It also includes originating loans secured by personal property and, to a very limited extent, unsecured personal loans. Consumer loans are originated for investment and for sale, either on a fixed-term basis or as a revolving line of credit. TCF has two consumer real estate loan sale programs: one that sells nationally originated consumer real estate junior lien loans and the other that originates first mortgage lien loans in its primary banking markets and sells the loans through correspondent relationships. TCF does not have any consumer real estate subprime lending programs. TCF continues to expand its junior lien lending business through a national lending platform focused on junior lien loans to high credit quality customers. Auto Finance Gateway One, headquartered in Anaheim, California, services loans on new and used autos. Effective April 1, 2017, the Company executed its strategic shift for auto finance from an originate-to-sell and originate-to-hold model to an entirely originate-to-hold model and effective December 1, 2017, the Company discontinued auto finance loan originations. Prior to April 1, 2017, loans were originated for investment and for sale. Gateway One will continue to service existing auto loans on its balance sheet and those serviced for others. 2 Wholesale Banking Wholesale Banking is comprised of commercial lending, leasing and equipment finance and inventory finance. TCF's wholesale banking strategy is primarily to originate high credit quality secured loans and leases for investment. Commercial With an emphasis on secured lending, essentially all of TCF's commercial loans were secured either by properties or other business assets at December 31, 2017 and 2016. Commercial real estate loans originated by TCF are secured by commercial real estate, including multi-family housing, office buildings, warehouse and industrial buildings, health care facilities, self-storage buildings, retail services buildings and hotel and motel buildings. The commercial real estate portfolio represented 77.3% and 80.2% of TCF's total commercial portfolio at December 31, 2017 and 2016, respectively. Commercial business loans originated by TCF are secured by various types of business assets including inventory, receivables, equipment or financial instruments. Commercial business loans are used for a variety of purposes, including working capital and financing the purchase of equipment. Leasing and Equipment Finance TCF provides a broad range of comprehensive lease and equipment finance products addressing the diverse financing needs of small to large companies in a growing number of select market segments including specialty vehicles, construction equipment, manufacturing equipment, golf cart and turf equipment, trucks and trailers, medical equipment, furniture and fixtures, technology and data processing equipment, and agricultural equipment. TCF's leasing and equipment finance businesses, TCF Equipment Finance, a division of TCF Bank, and Winthrop Resources Corporation ("Winthrop"), finance equipment in all 50 states and, to a limited extent, in foreign countries. TCF Equipment Finance delivers equipment finance solutions primarily to small and mid-size companies in various industries with significant diversity in the types of underlying equipment. Winthrop focuses on providing customized lease financing to meet the special needs of mid-size and large companies and health care facilities that procure high-tech essential business equipment such as computers, servers, telecommunication equipment, medical equipment and other technology equipment. Inventory Finance TCF Inventory Finance, Inc. ("TCF Inventory Finance") originates commercial, primarily variable- rate loans which are secured by the underlying floorplan equipment and supported by repurchase agreements from original equipment manufacturers. The operation focuses on establishing relationships with distributors, dealer buying groups and manufacturers, giving TCF access to thousands of independent retailers primarily in the areas of powersports and lawn and garden. TCF Inventory Finance operates in all 50 states and Canada and, to a limited extent, in other foreign countries. TCF Inventory Finance's portfolio balances are impacted by seasonal shipments and sales activities as dealers receive inventory shipments in anticipation of the upcoming selling season while carrying current season product. In 2009, TCF Inventory Finance formed a joint venture with The Toro Company ("Toro") called Red Iron Acceptance, LLC ("Red Iron"). Red Iron provides U.S. distributors and dealers and select Canadian distributors of the Toro® and Exmark® brands with reliable, cost-effective sources of financing. TCF maintains a 55% ownership interest in Red Iron, with Toro owning the other 45%. Enterprise Services Enterprise Services is comprised of (i) corporate treasury, which includes the Company's investment and borrowing portfolios and management of capital, debt and market risks, (ii) corporate functions, such as information technology, risk and credit management, bank operations, finance, investor relations, corporate development, legal and human capital management, that provide services to the operating segments, (iii) the Holding Company and (iv) eliminations. The Company's investment portfolio accounts for the earning assets within this segment. Borrowings may be used to offset reductions in deposits or to support lending activities. This segment also includes residual revenues and expenses representing the difference between actual amounts incurred by Enterprise Services and amounts allocated to the operating segments, including interest rate risk residuals such as funds transfer pricing mismatches. 3 Corporate Treasury Corporate Treasury's primary responsibility is management of liquidity, capital, interest rate risk, and investment and borrowing portfolios. Corporate Treasury has authority to invest in various types of liquid assets including, but not limited to, U.S. Department of the Treasury obligations and securities of various federal agencies and U.S. Government sponsored enterprises, obligations of states and political subdivisions, deposits of insured banks, bankers' acceptances and federal funds. Corporate Treasury also has the authority to enter into wholesale borrowing transactions which may be used to compensate for reductions in deposit inflows or net deposit outflows, or to support lending, leasing and other expansion activities. These borrowings may include Federal Home Loan Bank ("FHLB") advances, brokered deposits, repurchase agreements, federal funds and other permitted borrowings from creditworthy counterparties. Information concerning TCF's FHLB advances, repurchase agreements, federal funds and other borrowings is set forth in "Item 7. Management's Discussion and Analysis - Consolidated Financial Condition Analysis - Borrowings" and in Note 12. Short-term Borrowings and Note 13. Long-term Borrowings of Notes to Consolidated Financial Statements. Other Information Activities of Subsidiaries of TCF TCF's business operations include those conducted by direct and indirect subsidiaries of TCF Financial, all of which are consolidated for purposes of preparing TCF's consolidated financial statements. TCF Bank's subsidiaries principally engage in leasing, inventory finance and auto finance activities. See "Consumer Banking" and "Wholesale Banking" above for further information. Competition TCF competes with a number of depository institutions and financial service providers primarily based on price and service and faces significant competition in attracting and retaining deposits and in lending activities. Direct competition for deposits comes primarily from banks, savings institutions, credit unions and investment banks. Additional significant competition for deposits comes from institutions selling money market mutual funds and corporate and government securities. TCF competes for the origination of loans with banks, mortgage bankers, mortgage brokers, consumer and commercial finance companies, credit unions, insurance companies and savings institutions. TCF also competes nationwide with other companies and banks in the financing of equipment, inventory and automobiles (through December 1, 2017), leasing of equipment and origination of consumer real estate junior lien loans. The expanded use of the internet and the growth of financial technology companies partnering with financial services providers has increased competition for loan, lease and deposit products. Employees As of December 31, 2017, TCF had 6,116 employees, including 778 part-time employees. TCF provides its employees with comprehensive benefits, some of which are provided on a contributory basis, including medical and dental plans, a 401(k) savings plan with a company matching contribution, life insurance and short- and long-term disability coverage. Regulation TCF Financial, as a publicly held bank holding company, and TCF Bank, which has deposits insured by the Federal Deposit Insurance Corporation ("FDIC"), are subject to extensive regulation. Among other things, TCF Financial and TCF Bank are subject to minimum capital requirements, lending and deposit restrictions and numerous other requirements. TCF Financial's primary regulator is the Federal Reserve and TCF Bank's primary regulator is the Office of the Comptroller of the Currency ("OCC"). TCF's consumer products are also regulated by the Consumer Financial Protection Bureau ("CFPB"). 4   Regulatory Capital Requirements TCF Financial and TCF Bank are subject to various minimum regulatory capital requirements administered by the Federal Reserve and the OCC. These requirements include quantitative measures that assign risk weightings to assets and off-balance sheet items, as well as define and set minimum regulatory capital requirements. Failure to meet minimum capital requirements can initiate certain mandatory, and possible additional discretionary, actions by the federal banking regulators that, if undertaken, could have a material adverse effect on TCF's financial condition and results of operations. These federal banking regulators are required by law to take prompt action when institutions are viewed as engaging in unsafe or unsound practices or do not meet certain minimum capital requirements. In addition to other potential actions, failure to meet these requirements would result in limitations on capital distributions as well as executive bonuses. The Basel III capital standard phases in through 2019. Institutions not subject to the advanced approaches requirements were allowed to opt out of including components of accumulated other comprehensive income (loss) in common equity Tier 1 capital. TCF and TCF Bank made the one-time permanent election to not include accumulated other comprehensive income (loss) in regulatory capital. TCF and TCF Bank are subject to a capital conservation buffer. When fully phased-in on January 1, 2019, the Basel III capital standard will require TCF and TCF Bank to maintain a 2.5% capital conservation buffer, designed to absorb losses during periods of economic stress, composed entirely of common equity Tier 1 capital, on top of the minimum risk-weighted asset ratios, effectively resulting in minimum ratios for TCF Bank of (i) a common equity Tier 1 capital ratio of at least 7.0%, (ii) a Tier 1 risk-based capital ratio of at least 8.5% and (iii) a total risk-based capital ratio of at least 10.5%. TCF and TCF Bank exceeded the fully phased-in Basel III capital standard as of December 31, 2017. See Note 16.  Regulatory Capital Requirements of Notes to Consolidated Financial Statements for further information. Restrictions on Distributions  TCF Financial's ability to pay dividends is subject to limitations imposed by the Federal Reserve. In general, Federal Reserve regulatory guidelines require the board of directors of a bank holding company to consider a number of factors in determining the payment of dividends, including the quality and level of current and future earnings. Restricted retained earnings represents earnings legally appropriated to thrift bad debt reserves and deducted for federal income tax purposes in prior years and is generally not available for payment of cash dividends or other distributions to stockholders. See Note 15. Equity of Notes to Consolidated Financial Statements for further information on restricted retained earnings. Dividends or other capital distributions from TCF Bank to TCF Financial are an important source of funds to enable TCF Financial to pay dividends on its preferred and common stock, to pay TCF Financial's obligations or to meet other cash needs. The ability of TCF Financial and TCF Bank to pay dividends depends on regulatory policies and regulatory capital requirements and may be subject to regulatory approval. In general, TCF Bank may not declare or pay a dividend to TCF Financial in excess of 100% of its net retained earnings for the current year combined with its net retained earnings for the preceding two calendar years without prior approval of the OCC. The OCC also has the authority to prohibit the payment of dividends by a national bank when it determines such payments would constitute an unsafe and unsound banking practice. TCF Bank's ability to make capital distributions in the future may require regulatory approval and may be restricted by its federal banking regulators. TCF Bank's ability to make any such distributions will also depend on its earnings and ability to meet minimum regulatory capital requirements in effect during future periods. In the future, these capital adequacy standards may be higher than existing minimum regulatory capital requirements. See Note 16.  Regulatory Capital Requirements of Notes to Consolidated Financial Statements for further information.   In addition, income tax considerations may limit the ability of TCF Bank to make dividend payments in excess of its current and accumulated tax earnings. Annual dividend distributions in excess of earnings could result in a tax liability based on the amount of excess earnings distributed and current tax rates. Regulation of TCF and Affiliates and Insider Transactions  TCF Financial is subject to Federal Reserve regulations, examinations and reporting requirements applicable to bank holding companies. Subsidiaries of bank holding companies, like TCF Bank, are subject to certain restrictions in their dealings with holding company affiliates. A holding company must serve as a source of strength for its subsidiary banks and the Federal Reserve may require a holding company to contribute additional capital to an undercapitalized subsidiary bank. In addition, the OCC may assess TCF Financial if it believes the capital of TCF Bank has become impaired. If TCF Financial were to fail to pay such an assessment within three months, the Board of Directors would be required to cause the sale of TCF Bank's stock to cover a deficiency in the capital. In the event of a bank holding company's bankruptcy, any commitment by the bank holding company to a federal banking regulator to maintain the capital of a subsidiary bank would be assumed by the bankruptcy trustee and may be entitled to priority over other creditors. 5         Under the Bank Holding Company Act of 1956 ("BHCA"), Federal Reserve approval is required before acquiring more than 5% control, or substantially all of the assets, of another bank, or bank holding company, or merging or consolidating with such a bank or bank holding company. The BHCA also generally prohibits a bank holding company, with certain exceptions, from acquiring direct or indirect ownership or control of more than 5% of the voting shares of any company which is not a bank or bank holding company, or from engaging directly or indirectly in activities other than those of banking, managing or controlling banks, providing services for its subsidiaries, or conducting activities permitted by the Federal Reserve as being closely related to the business of banking. Further restrictions or limitations on acquisitions or establishing financial subsidiaries may also be imposed by TCF's regulators or examiners. Restrictions on Acquisitions and Changes in Control  Under federal and state law, merger and branch acquisition transactions may be subject to certain restrictions, including certain nationwide and statewide insured deposit maximum concentration levels or other limitations. In addition, federal and state laws and regulations contain a number of provisions which impose restrictions on changes in control of financial institutions such as TCF Bank and which require regulatory approval prior to any such changes in control. Insurance of Accounts  TCF Bank is a member of the FDIC, which maintains the Deposit Insurance Fund ("DIF"). The FDIC insures deposits up to prescribed limits for each depositor through the DIF, which is funded through assessments on member institutions. To maintain the DIF, member institutions are assessed an insurance premium based on an assessment base and an assessment rate. The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act") gave the FDIC much greater discretion to manage the DIF and also changed the assessment base from domestic deposits to average total assets less tangible equity. Additionally, the Dodd-Frank Act raised the minimum designated reserve ratio ("DRR") to 1.35% of estimated insured deposits from 1.15% and required this new minimum be reached by September 30, 2020. On July 1, 2016 an additional surcharge of 4.5 cents for each $100 of an institution's assessment base in excess of $10.0 billion went into effect to ensure the DRR reaches this new minimum by the required date. The DIF ratio calculated by the FDIC using estimated insured deposits as of September 30, 2017 was 1.28%. In 2017, insurance premiums on bank deposits insured by the FDIC for banks with at least $10.0 billion in total assets ranged from 1.5 cents to 40 cents per $100 of the institution's assessment base. TCF's FDIC insurance expense was $16.0 million, $15.9 million and $20.3 million in 2017, 2016 and 2015, respectively. In addition to deposit insurance premium assessments from the FDIC, additional assessments may be imposed by the Financing Corporation, a separate U.S. government agency affiliated with the FDIC, to pay for the interest cost of Financing Corporation bonds. As of December 31, 2017, the Financing Corporation assessment rate was 46 cents for each $10,000 of the institution's assessment base. Examinations and Regulatory Sanctions  TCF is subject to periodic examination by the Federal Reserve, the OCC, the CFPB and the FDIC. Federal banking regulators may impose a number of restrictions or new requirements on institutions, including, but not limited to, growth limitations, dividend restrictions, increased regulatory capital requirements, increased loan and lease loss reserve requirements, increased supervisory assessments, activity limitations or other restrictions that could have an adverse effect on such institutions, their holding companies or holders of their debt and equity securities. Various enforcement remedies, including civil money penalties, may be assessed against an institution or an institution's directors, officers, employees, agents or independent contractors. Certain enforcement actions may not be publicly disclosed by TCF or its federal banking regulators. Subsidiaries of TCF Bank are also subject to state and/or self-regulatory organization licensing, regulation and examination requirements in connection with certain activities. See "Item 1A. Risk Factors." National Bank Investment Limitations  Permissible investments by national banks are limited by the National Bank Act of 1864, as amended, and by rules of the OCC. Non-traditional bank activities permitted by the Gramm-Leach- Bliley Act of 1999 will subject a bank to additional regulatory limitations or requirements, including a required regulatory capital deduction and application of transactions with affiliates limitations in connection with such activities. 6 Taxation  Federal Taxation  TCF's federal income tax returns are open and subject to examination for 2014 and later tax return years. The Tax Cuts and Jobs Act ("Tax Reform") was enacted on December 22, 2017, which resulted in the re- measurement of deferred tax assets and deferred tax liabilities to account for the future impact of lower corporate tax rates on these deferred amounts. As a result of Tax Reform, TCF recorded a reasonable estimate of a net tax benefit of $130.7 million in 2017, primarily resulting from the re-measurement of the Company's estimated net deferred tax liability. State Taxation  TCF and/or its subsidiaries currently file tax returns in all state and local taxing jurisdictions which impose corporate income, franchise or other taxes. TCF's various state income tax returns are generally open for 2013 and later tax return years based on individual state statutes of limitation. The methods of filing and the methods for calculating taxable and apportionable income vary depending on the laws of each taxing jurisdiction. Foreign Taxation TCF and/or its subsidiaries currently file tax returns in Canada and certain Canadian provinces which impose corporate income taxes. TCF's various foreign income tax returns are open and subject to examination for 2013 and later tax return years. The methods of filing and the methods for calculating taxable and apportionable income vary depending on the laws of each taxing jurisdiction. See "Item 7. Management's Discussion and Analysis - Consolidated Income Statement Analysis - Income Taxes", Note 2. Summary of Significant Accounting Policies and Note 14. Income Taxes of Notes to Consolidated Financial Statements for further information regarding TCF's income taxes.

Risk Factors An investment in securities issued by TCF, including an investment in TCF's common and preferred stock, involves certain risks that should be considered carefully. The most significant risks that management believes affect TCF are described below. Any of the risks described below may have a material impact on TCF's financial condition, results of operations or reputation. To the extent that any of the information contained in this Annual Report on Form 10-K is forward-looking, the risk factors set forth below also are cautionary statements identifying important factors that could cause TCF's actual results to differ materially from those expressed in any forward-looking statements. TCF's financial results are significantly affected by general economic and political conditions. TCF's operations and profitability are impacted by both business and economic conditions generally, as well as those in the local markets in which TCF operates. Economic conditions have a significant impact on the demand for TCF's products and services, as well as the ability of its customers to repay loans and leases, the value of the collateral securing loans and leases, the ability of TCF to sell loans, the stability of its deposit funding sources and sales revenue at the end of contractual lease terms. A significant decline in general economic conditions caused by inflation, recession, unemployment, changes in securities markets, changes in housing market prices or other factors could impact economic conditions and, in turn, could have a material adverse effect on TCF's financial condition and results of operations. Additionally, adverse economic conditions may result in a decline in demand for equipment that TCF leases or finances, which could result in a decline in the amount of new equipment being placed in service, as well as declines in the values of collateral already in service. Adverse economic conditions may also hinder TCF from expanding the inventory finance business by limiting its ability to attract and retain manufacturers and dealers as expected. Any such difficulties in TCF's leasing and equipment and inventory finance businesses could have a material adverse effect on its financial condition and results of operations. TCF's financial results are subject to interest rate risk. TCF's earnings and cash flows largely depend upon its net interest income. Interest rates are highly sensitive to many factors that are beyond TCF's control, including general economic conditions and policies of various governmental and regulatory agencies, including the Federal Reserve. Changes in monetary policy, including changes in interest rates, could influence not only the interest TCF receives on loans, leases and other investments and the amount of interest TCF pays on deposits and other borrowings, but such changes could also affect: (i) TCF's ability to originate loans and leases and attract or retain deposits; (ii) the fair value of TCF's financial assets and liabilities and (iii) the average duration of TCF's interest-earning assets. If the interest rates paid on deposits and other borrowings increase at a faster rate than the interest rates received on loans, leases and other investments, then TCF's net interest income and earnings could be adversely affected. Earnings could also be adversely affected if the interest rates received on loans, leases and other investments fall more quickly than the interest rates paid on deposits and other borrowings. Although management believes it has implemented effective asset and liability management strategies, any substantial, unexpected or prolonged change in market interest rates could have a material adverse effect on its financial condition and results of operations. An inability to obtain needed liquidity could have a material adverse effect on TCF's financial condition and results of operations. TCF's liquidity could be limited by an inability to access the capital markets or unforeseen outflows of cash, which could arise due to circumstances outside of its control, such as a general market disruption or an operational problem that affects TCF or third parties. TCF's credit rating is important to its liquidity. A reduction or anticipated reduction in TCF's credit ratings could adversely affect the ability of TCF Bank and its subsidiaries to lend and adversely affect its liquidity and competitive position, increase its borrowing costs, limit its access to the capital markets or trigger unfavorable contractual obligations. An inability to meet its funding needs on a timely basis could have a material adverse effect on TCF's financial condition and results of operations. 8   TCF Financial relies on dividends from TCF Bank for most of its liquidity. TCF Financial is a separate and distinct legal entity from TCF Bank. TCF Financial's liquidity comes principally from dividends from TCF Bank. These dividends, which are limited by various federal and state regulations, are the principal source of funds TCF Financial uses to pay dividends on its preferred and common stock and to meet its other cash needs. In the event TCF Bank is unable to pay dividends to TCF Financial, it may not be able to pay dividends or other obligations, which could have a material adverse effect on TCF's financial condition and results of operations. Competition for growth in deposits and evolving payment system developments could increase TCF's funding costs. TCF relies on bank deposits to be a low cost and stable source of funding. TCF competes with banks and other financial institutions for deposits and it is expected that competition for deposits will continue to increase. If TCF's competitors raise the rates they pay on deposits, TCF may experience either a loss of deposits or an increase in rates paid by TCF to avoid losing deposits. Industry developments involving payment system changes could also impose additional costs. Losses of deposits may require TCF to address its liquidity needs in ways that increase its funding costs. Increased funding costs could reduce TCF's net interest margin and net interest income, which could have a material adverse effect on TCF's financial condition and results of operations. The soundness of other financial institutions could adversely affect TCF's financial results. TCF's ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. TCF routinely executes transactions with counterparties in the financial industry, including brokers and dealers, commercial banks and other institutional clients. As a result, defaults by, or even speculation regarding the soundness of, any financial institution, or the financial services industry generally, could lead to losses by, or other adverse consequences to, TCF or a counterparty. Many of these transactions expose TCF to credit risk in the event of default of the counterparty or client. In addition, TCF's credit risk may be exacerbated if the collateral held by TCF cannot be realized or is liquidated at prices not sufficient to recover the full amount of the financial exposure. Any such losses could have a material adverse effect on TCF's financial condition and results of operations. TCF relies on its systems and counterparties, including reliance on other companies for the provision of key components of its business infrastructure, and any failures could have a material adverse effect on its financial condition and results of operations. TCF, through systems and counterparties, settles funds on behalf of financial institutions, other businesses and consumers and receives funds from payment networks, consumers and other paying agents. TCF's businesses depend on their ability to process, record and monitor a large number of complex transactions and process large amounts of information, including employee and financial information. Any disruptions to these systems may result in significant costs and other adverse developments. Although we have plans, policies and procedures designed to prevent or limit the negative effect of these disruptions, there can be no assurance that these will be successful. Our failure to effectively mitigate or promptly remediate any disruptions could result in an inability to perform necessary business functions, damage our reputation, result in a loss of customer business or confidence, subject us to regulatory scrutiny or expose us to litigation or other financial liability, any of which could materially affect us, including our results of operations. Third party vendors provide key components of TCF's business infrastructure, such as internet connections, network access and transaction and other processing services. While TCF has selected these third party vendors carefully, it does not control their actions. Any problems experienced or caused by these third parties, including inadequate or interrupted service, could adversely affect TCF's ability to process, record or monitor transactions, or to deliver products and services to its customers and to conduct its business. Replacing these third party vendors could also entail significant delay and expense. TCF also may be subject to disruptions of its operating systems arising from events that are wholly or partially beyond its control, which may include, for example, computer viruses, electrical or telecommunications outages, natural disasters, terrorist acts or other damage to property or physical assets. Such disruptions may give rise to loss of services to customers and loss or liability to TCF. Any system failure could have a material adverse effect on TCF's financial condition and results of operations. If any of TCF's financial, accounting or other data processing systems fail or if personal information of TCF's customers or clients were mishandled or misused (whether by employees or counterparties), TCF could suffer regulatory consequences, reputational damage and financial losses, any of which could have a material adverse effect on its financial condition and results of operations. 9 TCF faces cyber-security and other external risks, including "denial of service," "hacking," "ransomware" and "identity theft," that could adversely affect TCF's reputation and could have a material adverse effect on TCF's financial condition and results of operations. TCF's computer systems and network infrastructure present security risks and could be susceptible to cyber-attacks, such as denial of service attacks, hacking, terrorist activities or identity theft. Hacking and identity theft risks, in particular, could cause serious financial and reputational harm. Cyber threats are rapidly evolving and TCF may not be able to anticipate or prevent all such attacks. While TCF does not believe it has experienced a material cyber-security breach, TCF experiences periodic threats to its data and systems, including malware and computer virus attacks, attempted unauthorized access of accounts and attempts to disrupt its systems. TCF may incur increasing costs in an effort to minimize these risks, could be held liable for and could suffer reputational damage as a result of any security breach or loss. In addition, there have been increasingly sophisticated and large-scale efforts on the part of third parties to breach data security with respect to financial transactions, including by intercepting account information at locations where customers make purchases or withdraw money, as well as through the use of social engineering schemes such as "phishing." For example, many retailers have reported data breaches resulting in the loss of customer information and many financial institutions have experienced losses as account information has been stolen through the use of skimmers placed on ATMs and point of sale terminals. In the event that third parties are able to misappropriate financial information of TCF's customers, even if such breaches take place due to weaknesses in other parties' security protections, TCF could suffer reputational damage or financial losses which could have a material adverse effect on its financial condition and results of operations. The success of TCF's supermarket branches depends on the continued long-term success and viability of TCF's supermarket partners, TCF's ability to maintain licenses or lease agreements for its supermarket locations and customer preferences. A significant financial decline or change in ownership involving one of TCF's supermarket partners, including Jewel- Osco or SUPERVALU Inc., could result in the loss of supermarket branches or could increase costs to operate the supermarket branches. At December 31, 2017, TCF had 128 supermarket branches. Supermarket banking continues to play an important role in TCF's deposit account strategy. TCF is subject to the risk, among others, that its license or lease for a location or locations will terminate upon the sale or closure of that location or locations by the supermarket partner or that we may not be able to renew branch leases with our supermarket partners on favorable terms, or at all. Also, difficult economic conditions, financial or labor difficulties in the supermarket industry, or a decrease in customer utilization of traditional bank branches may reduce activity in TCF's supermarket branches. Although utilization of these branches may decrease, the nature of these leases with our supermarket partners generally do not allow us to terminate significant numbers of individual branches. Because these leases are generally all renewed together, in the event of a decrease in customer utilization there may be limited opportunities to terminate unprofitable branch leases. Any of the above risks could have a material adverse effect on TCF's financial condition and results of operations. New lines of business or new products and services may subject TCF to additional risk. From time to time, TCF may implement new lines of business or offer new products and services within existing lines of business. There are substantial risks and uncertainties associated with these efforts, particularly in instances where the markets are not fully developed. In developing and marketing new lines of business and new products or services, TCF may invest significant time and resources. Initial timetables for the introduction and development of new lines of business and new products or services may not be achieved and price and profitability targets may not prove feasible. External factors, such as compliance with regulations, competitive alternatives and shifting market preferences may also impact the successful implementation of a new line of business or a new product or service. Furthermore, any new line of business or new product or service could have a significant impact on the effectiveness of TCF's system of internal controls. Failure to successfully manage these risks in the development and implementation of new lines of business and new products or services could have a material adverse effect on TCF's financial condition and results of operations. 10 Increased competition in the already highly competitive financial services industry could have a material adverse effect on TCF's financial condition and results of operations. The financial services industry is highly competitive and could become even more competitive as a result of legislative, regulatory and technological changes, as well as continued industry consolidation, which may increase in connection with current economic and market conditions. TCF competes with other commercial banks, savings and loan associations, mutual savings banks, finance companies, mortgage banking companies, credit unions and investment companies. In addition, technology has lowered barriers to entry and made it possible for non-banks to offer products and services traditionally only provided by banks, such as providing loans through peer-to-peer lending. Some of TCF's competitors have fewer regulatory constraints or lower cost structures. Also, the potential need to adapt to industry changes in information technology systems, on which TCF and the financial services industry generally highly depend, could present operational issues and require considerable capital spending. Further, decreased underwriting standards of competitors may result in lower interest rates on loans originated by TCF or lower loan volumes originated by TCF. As a result, any increased competition in the already highly competitive financial services industry could have a material adverse effect on TCF's financial condition and results of operations. The allowance for loan and lease losses maintained by TCF may not be sufficient to cover actual losses experienced by TCF and losses in excess of TCF's allowance could have a material adverse effect on TCF's financial condition and results of operations. TCF maintains an allowance for loan and lease losses, which is a reserve established through a provision for loan and lease losses charged to expense, which represents management's best estimate of probable credit losses incurred within the existing portfolio of loans and leases. The level of the allowance for loan and lease losses reflects management's continuing evaluation of industry concentrations, specific credit risks, loan and lease loss experience, current loan and lease portfolio quality, present economic, political and regulatory conditions and unidentified losses in the current loan and lease portfolio. The determination of the appropriate level of the allowance for loan and lease losses involves a high degree of subjectivity and requires management to make significant estimates of current credit risks using qualitative and quantitative factors, each of which is subject to significant change. Changes in economic conditions affecting customers, new information regarding existing loans and leases, identification of additional problem loans and leases, lower than expected recoveries in the case of default and other factors may require an increase in the allowance for loan and lease losses. In addition, federal banking regulators periodically review TCF's allowance for loan and lease losses and may require an increase in the provision for loan and lease losses or the recognition of additional loan and lease charge-offs, based on judgments different than those of management. An increase in the allowance for loan and lease losses would result in a decrease in net income, and possibly risk-based capital, and could have a material adverse effect on TCF's financial condition and results of operations. TCF is subject to extensive government regulation and supervision, and changes in applicable laws and regulations, or their enforcement, could have a material adverse effect on TCF's financial results. TCF Financial, its subsidiary TCF Bank and certain indirect subsidiaries are subject to extensive federal and state regulation and supervision. Banking regulations are primarily intended to protect bank customers, depositors' funds, federal deposit insurance funds and the banking system as a whole, not stockholders. These regulations affect TCF's revenues, lending practices, capital structure, investment practices, dividend policy and growth, among other things. Congress and federal regulators continually review banking laws, regulations and policies for possible changes. Many new banking rules are issued with limited interpretive guidance. 11 Future changes in regulations, regulatory policies, interpretation and enforcement of statutes, regulations or policies could result in reduced revenues, increased compliance burdens, additional costs, limits on the types of financial services and products we may offer or increased competition from non-banks offering competing financial services and products, among other things. Future legislative and regulatory initiatives cannot be fully or accurately predicted. Such proposals may impose more stringent standards than currently applicable or anticipated with respect to capital and liquidity requirements for depository institutions. For example, the CFPB has examination and enforcement authority over TCF Bank and its subsidiaries, and broad rulemaking authority to administer and carry out the purposes and objectives of the federal consumer financial laws with respect to all financial institutions that offer financial products and services to consumers. The CFPB is authorized to make rules identifying and prohibiting acts or practices that are unfair, deceptive or abusive in connection with any transaction with a consumer for a consumer financial product or service, or the offering of a consumer financial product or service. Uncertainties remain concerning how the term "abusive" will be enforced. In recent years there has been an increase in the frequency of enforcement actions brought by federal banking regulators, such as the CFPB, dealing with matters such as indirect auto lending, fair lending, account fees, loan servicing and other products and services provided to customers. For example, on January 19, 2017, the CFPB filed a civil lawsuit against TCF Bank in the United States District Court for the District of Minnesota (the "Court"), captioned Consumer Financial Protection Bureau v. TCF National Bank, alleging violations of the Consumer Financial Protection Act ("CFPA") and Regulation E §1005.17, in connection with TCF Bank's practices administering checking account overdraft program "opt-in" requirements from 2010 to early 2014. In its complaint, the CFPB seeks, among other relief, redress for consumers, injunctive relief and unspecified penalties. On September 8, 2017, the Court issued a ruling on the motion made by TCF Bank to dismiss the complaint of the CFPB. In its ruling, the Court granted TCF Bank's motion to dismiss the CFPB's Regulation E claims and also dismissed the CFPB's unfair, deceptive and abusive conduct claims under the CFPA for periods prior to July 21, 2011. The Court did not grant TCF Bank's motion to dismiss CFPA claims for periods on or after July 21, 2011. TCF Bank rejects the claims made by the CFPB in its complaint and intends to continue to vigorously defend against the CFPB's allegations. However, the ultimate resolution of this lawsuit and any other proceeding, action or matter arising from the same or similar facts or practices is uncertain, and this lawsuit and any other such proceedings, actions or matters may result in costs, losses, fines, penalties, restitution, injunctive relief, changes to our business practices and regulatory scrutiny, enforcement or restrictions which, individually or in the aggregate, could have a material adverse effect on our reputation, results of operations, cash flows, financial position, ability to offer certain products and business and prospects generally. While TCF has policies and procedures designed to prevent violations of laws, regulations and regulatory policies, and to ensure compliance with new or changed laws, regulations and regulatory policies, there can be no assurance that violations will not occur and failure to comply could result in reputational damage, remediation, disgorgement, penalties, other monetary relief, injunctive relief or changes to TCF's business practices or operations, any of which could have a material adverse effect on its financial condition and results of operations. TCF's earnings are significantly affected by the fiscal and monetary policies of the federal government and its agencies, as well as other legal changes affecting businesses and consumers. The policies of the Federal Reserve impact TCF significantly. The Federal Reserve regulates the supply of money and credit in the U.S. Its policies directly and indirectly influence the rate of interest earned on loans and leases and paid on borrowings and interest-bearing deposits, and also affect the value of financial instruments that TCF holds. Those policies determine, to a significant extent, the cost of funds for lending and investing. Changes in those policies are beyond TCF's control and are difficult to predict. Federal Reserve policies can also affect TCF's borrowers, potentially increasing the risk that they may fail to repay their loans or leases. For example, a tightening of the money supply by the Federal Reserve could increase unemployment or reduce the demand for a borrower's products and services. This could adversely affect the borrower's earnings and ability to repay its loan or lease. As a result, changes to the fiscal and monetary policies by the Federal Reserve could have a material adverse effect on TCF's financial condition and results of operations. In addition, legal changes affecting consumers and businesses, including the deductibility or other tax attributes associated with certain products, may significantly decrease the demand for certain products that we offer. For example, Tax Reform limits the tax deductibility of interest paid on home equity loans to those loans used to purchase or substantially improve qualified residences, which may decrease consumer demand for such loan products. 12 TCF's framework for managing risks may not be effective in mitigating risk and any resulting loss. TCF's risk management framework seeks to mitigate risk and any resulting loss. TCF has established processes intended to identify, measure, monitor, report and analyze the types of risk to which TCF is subject, including legal and compliance, operational, reputational, strategic and market risk such as interest rate, credit, liquidity and foreign currency risk. However, as with any risk management framework, there are inherent limitations to TCF's risk management strategies. There may exist, or develop in the future, risks that TCF has not appropriately anticipated or identified. Any future breakdowns in TCF's risk management framework could have a material adverse effect on its financial condition and results of operations. Damage to TCF's reputation could have a material adverse effect on TCF’s financial results. Reputational risk, or the risk to earnings and capital from negative public opinion, is inherent in TCF's business. Negative public opinion could adversely affect TCF's ability to keep and attract employees and customers and expose it to adverse legal and regulatory consequences. Negative public opinion could result from TCF's actual or alleged conduct in any number of activities, including lending practices, corporate governance, regulatory compliance, mergers and acquisitions, disclosure, sharing or inadequate protection of customer information or from actions taken by government regulators and community organizations in response to such conduct, and could be exacerbated by negative publicity. Because TCF conducts most of its businesses under the "TCF" brand, negative public opinion about one business could affect all of TCF's businesses. Failure to keep pace with technological change could adversely affect TCF's business. The financial services industry is continually undergoing rapid technological change with frequent introductions of new technology-driven products and services. TCF's future success depends, in part, upon its ability to address the needs of its customers by using technology to provide products and services that will satisfy customer demands, as well as to create additional efficiencies in its operations. Many of TCF's competitors have substantially greater resources to invest in technological improvements. TCF may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to its customers. Failure to successfully keep pace with technological change affecting the financial services industry could have a material adverse effect on TCF's financial condition and results of operations. The Company is subject to certain risks related to originating and selling loans that could have a material adverse effect on TCF's financial condition and results of operations. TCF relies on the sale of loans to generate earnings and manage its liquidity and capital levels, as well as geographical and product diversity in its loan portfolio. Disruptions in the financial markets, decrease in demand for loans which we sell, changes to laws or regulations that reduce the attractiveness of such loans to purchasers of the loans or a decrease in the willingness of purchasers to purchase loans from TCF, or in general, could require TCF to decrease its lending activities or retain a greater portion of the loans it originates. Selling fewer loans would result in a decrease in the gains recognized on the sale of loans, would decrease TCF's capital ratios as a result of the increase of risk weighted assets, could result in decreased liquidity and could result in increased credit risk as TCF's loan portfolio increased in size, any of which could have a material adverse effect on TCF's financial condition and results of operations. The structure of certain loan sales may result in the retention of credit risk. TCF may receive interest-only strips in connection with certain of its loan sales. The interest-only strip is recorded at fair value, which represents the present value of future cash flows expected to be received by TCF. The value of these interest-only strips may be affected by factors such as changes in the behavior patterns of customers (including defaults and prepayments), changes in the strength of the economy and developments in the interest rate markets; therefore, actual performance may differ from TCF's expectations. The impact of such factors could have a material adverse effect on the value of these interest- only strips and on TCF's financial condition and results of operations. 13 When loans are sold or securitized, it is customary to make representations, warranties and covenants to the purchaser or investors about the loans, including the manner in which they were originated and will be serviced. These agreements generally require the repurchase of loans or indemnification in the event TCF breaches these representations, warranties or covenants and such breaches are not cured. In addition, some agreements contain a requirement to repurchase loans as a result of early payoffs by the borrower, early payment default of the borrower or the failure to obtain valid title. TCF has not made significant repurchases of sold loans. A material increase in the amount of loans repurchased could have a material adverse effect on TCF's financial condition and results of operations. Financial institutions depend on the accuracy and completeness of information about customers and counterparties. In deciding whether to extend credit or enter into other transactions, TCF may rely on information furnished by or on behalf of customers and counterparties, including financial statements, credit reports and other financial information. TCF may also rely on representations of those customers, counterparties or other third parties, such as independent auditors, as to the accuracy and completeness of that information. Reliance on inaccurate or misleading financial statements, credit reports or other financial information could cause TCF to enter into unfavorable transactions which could have a material adverse effect on TCF's financial condition and results of operations. The failure to attract and retain key personnel could have a material adverse effect on TCF's financial condition and results of operations. TCF's success depends to a large extent upon its key personnel, including its ability to attract and retain such personnel. The loss of key personnel could have a material adverse impact on TCF's business because of their skills, market knowledge, industry experience and the difficulty of promptly finding qualified replacements. Additionally, portions of TCF's business are relationship driven and many of TCF's key personnel have extensive customer relationships. Loss of key personnel to a competitor could result in the loss of some of TCF's customers. As a result, a failure to attract and retain key personnel could have a material adverse effect on TCF's financial condition and results of operations. Acquisitions may disrupt TCF's business and dilute stockholder value. TCF regularly evaluates merger and acquisition opportunities and conducts due diligence activities related to possible transactions with banks or other financial institutions. As a result, negotiations may take place and future mergers or acquisitions involving cash, debt or equity securities may occur at any time. Acquiring other banks, businesses or branches involves various risks, such as: difficulty in estimating the value of the target company; payment of a premium over book and market values that may dilute TCF's tangible book value and earnings per share in the short- and long- term; potential exposure to unknown or contingent liabilities of the target company; exposure to potential asset quality issues of the target company; volatility in reported income as goodwill impairment losses could occur irregularly and in varying amounts; difficulty and expense of integrating the operations and personnel of the target company; inability to realize the expected revenue increases, cost savings, increases in geographic or product presence or other projected benefits; potential disruption to TCF's business; potential diversion of TCF management's time and attention; potential loss of key employees and customers of TCF or the target company; and potential changes in banking or tax laws or regulations that may affect the target company, any of which could have a material adverse effect on TCF's financial condition and results of operations. Consumers may decide not to use banks to complete their financial transactions. Technology and other changes are allowing consumers to complete financial transactions through alternative methods that historically have involved banks. For example, consumers can now maintain funds that would have previously been held as traditional bank deposits in brokerage accounts, online bank accounts, mutual funds or general-purpose reloadable prepaid cards. Consumers can also complete transactions such as paying bills, transferring funds and obtaining loans directly without the assistance of banks. The process of eliminating banks as intermediaries could result in the loss of fee income, as well as the loss of customer deposits and the related income generated from those deposits. The loss of these revenue streams and the loss of lower-cost deposits as a source of funds could have a material adverse effect on TCF's financial condition and results of operations. 14 Changes in accounting policies or in accounting standards could materially affect how TCF reports its financial condition and results of operations. TCF's accounting policies are fundamental to the understanding of its financial condition and results of operations. Some of these policies require the use of estimates and assumptions that may affect the value of TCF's assets or liabilities and results of operations. Some of TCF's accounting policies are critical because they require management to make difficult, subjective and complex judgments about matters that are inherently uncertain and because materially different amounts would be reported if different estimates or assumptions were used. If such estimates or assumptions underlying the financial statements are incorrect, TCF could experience material losses. From time to time the Financial Accounting Standards Board and the SEC change the financial accounting and reporting standards or the interpretation of those standards that govern the preparation of TCF's financial statements. These changes are beyond TCF's control, can be difficult to predict and could materially impact how TCF reports its financial condition and results of operations. Additionally, TCF could be required to apply a new or revised standard retrospectively, resulting in it restating prior period financial statements in material amounts. TCF is subject to examinations and challenges by tax authorities that could adversely affect TCF's results of operations and financial condition. TCF is subject to federal, state and foreign income tax regulations, which often require interpretation due to their complexity. Changes in income tax regulations, including those resulting from the enactment of Tax Reform, or in how the regulations are interpreted could have a material adverse effect on TCF's results of operations. In the normal course of business, TCF is routinely subject to examinations and challenges from taxing authorities regarding its tax positions. Taxing authorities have been aggressive in challenging tax positions taken by financial institutions. These tax positions may relate to tax compliance, sales and use, franchise, gross receipts, payroll, property and income tax issues, including tax base, apportionment and tax credit planning. These challenges may result in adjustments to the timing or amount of taxable income or deductions, or the allocation of income among tax jurisdictions. If any such challenges are made and are not resolved in TCF's favor, they could have a material adverse effect on TCF's financial condition and results of operations. Significant legal actions could subject TCF to substantial uninsured liabilities. TCF can be subject to claims and legal actions related to its operations. These claims and legal actions, including supervisory or enforcement actions by TCF's regulators and other government authorities or private litigation, could result in large monetary awards or penalties, as well as significant defense costs. While TCF maintains insurance coverage in amounts and with deductibles that it believes are appropriate for its operations, such insurance does not cover all types of liability, including regulatory fines or penalties, and may not continue to be available to TCF at a reasonable cost, or at all. As a result, TCF may be exposed to substantial uninsured liabilities, which could have a material adverse effect on TCF's financial condition and results of operations. In addition, customers may make claims and take legal action pertaining to TCF's deposit products and sale or servicing of its loan and lease products. Whether or not such claims and legal action have merit, they may result in significant financial liability and could adversely affect the market perception of TCF and its products and services, as well as impact customer demand for those products and services. Any financial liability or reputational damage could have a material adverse effect on TCF's financial condition and results of operations. In particular, the financial services industry has increasingly been targeted by lawsuits alleging infringement of patent rights, often from patent holding companies seeking to monetize patents they have purchased or otherwise obtained. Regardless of the scope or validity of such patents or other intellectual property rights, or the merits of any claims by potential or actual litigants, the Company may have to engage in protracted and costly litigation which may be time consuming and disruptive to TCF's operations and management. If the Company is found to infringe on one or more patents or other intellectual property rights, it may be required to pay substantial damages or royalties to a third-party, or it may be subject to a temporary or permanent injunction prohibiting the Company from utilizing certain technologies. 15 TCF's internal controls may be ineffective. Management regularly reviews and updates TCF's internal controls, disclosure controls and procedures and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of TCF's controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on its financial condition and results of operations. TCF is subject to environmental liability and risks related to natural disasters that are associated with lending activities. A significant portion of TCF's loan portfolio is secured by real property. In the ordinary course of business, TCF may foreclose on and take title to properties securing certain loans. In doing so, there is a risk that hazardous or toxic substances could be found on these properties. If hazardous or toxic substances are found, TCF may be liable for remediation costs, as well as for personal injury and property damage. Environmental laws may require TCF to incur substantial expenses and may materially reduce the affected property's value or limit TCF's ability to use or sell the affected property. In addition, future laws or more stringent interpretations or enforcement policies with respect to existing laws may increase TCF's exposure to environmental liability. The remediation costs and any other financial liabilities associated with an environmental hazard could have a material adverse effect on TCF's financial condition and results of operations. In addition, severe weather, earthquakes, other natural disasters, pandemics, acts of war or terrorism and other adverse external events could have a significant impact on our lending business. Such events could impair the ability of borrowers to repay outstanding loans, impair the value of collateral securing loans, cause significant property damage and/or cause us to incur additional expenses. Because our lending businesses are geographically diverse, those businesses are likely to be impacted more often by natural disasters, including hurricanes, flooding, fires and earthquakes, which have caused extensive damage in various parts of the United States in which they conduct business. The occurrence of any such events could have a material adverse effect on our financial condition and results of operations. Item 1B. Unresolved Staff Comments None. Item 2. Properties Offices TCF owns its headquarters office in Wayzata, Minnesota. Other operations facilities, located in Minnesota, Illinois, California and South Dakota, are either owned or leased. These facilities are predominantly utilized by the Consumer Banking and Wholesale Banking reportable segments. Several facilities in Minnesota are also utilized by the Enterprise Services reportable segment. At December 31, 2017, TCF owned the buildings and land for 144 of its bank branch offices, owned the buildings and leased the land for 26 of its bank branch offices and leased or licensed the remaining 150 bank branch offices, all of which are functional and appropriately maintained and are utilized by both the Consumer Banking and Wholesale Banking reportable segments. These branch offices are located in Illinois, Minnesota, Michigan, Colorado, Wisconsin, Arizona and South Dakota. For further information on premises and equipment, see Note 8. Premises and Equipment, Net of Notes to Consolidated Financial Statements. 16 Item 3. Legal Proceedings From time to time, TCF is a party to legal proceedings arising out of its lending, leasing and deposit operations, including foreclosure proceedings and other collection actions as part of its lending and leasing collections activities. TCF may also be subject to regulatory examinations and enforcement actions brought by federal regulators, including the SEC, the Federal Reserve, the OCC and the CFPB, and TCF's federal regulators may impose sanctions on TCF for failures related to regulatory compliance. From time to time, borrowers and other customers, and employees and former employees, have also brought actions against TCF, in some cases claiming substantial damages. TCF and other financial services companies are subject to the risk of class action litigation. Litigation is often unpredictable and the actual results of litigation cannot be determined, and therefore the ultimate resolution of a matter and the possible range of loss associated with certain potential outcomes cannot be established. Except as discussed below, based on our current understanding of TCF's pending legal proceedings, management does not believe that judgments or settlements arising from pending or threatened legal matters, individually or in the aggregate, would have a material adverse effect on the consolidated financial position, operating results or cash flows of TCF. On January 19, 2017, the CFPB filed a civil lawsuit against TCF Bank in the United States District Court for the District of Minnesota (the "Court"), captioned Consumer Financial Protection Bureau v. TCF National Bank, alleging violations of the Consumer Financial Protection Act ("CFPA") and Regulation E, §1005.17 in connection with TCF Bank's practices administering checking account overdraft program "opt-in" requirements from 2010 to early 2014. In its complaint, the CFPB seeks, among other relief, redress for consumers, injunctive relief and unspecified penalties. On September 8, 2017, the Court issued a ruling on the motion made by TCF Bank to dismiss the complaint of the CFPB. In its ruling, the Court granted TCF Bank's motion to dismiss the CFPB's Regulation E claims and also dismissed the CFPB's unfair, deceptive and abusive conduct claims under the CFPA for periods prior to July 21, 2011. The Court did not grant TCF Bank's motion to dismiss CFPA claims for periods on or after July 21, 2011. TCF Bank rejects the claims made by the CFPB in its complaint and intends to continue to vigorously defend against the CFPB's allegations. However, the ultimate resolution of this lawsuit and any other proceeding, action or matter arising from the same or similar facts or practices is uncertain, and this lawsuit and any other such proceedings, actions or matters may result in costs, losses, fines, penalties, restitution, injunctive relief, changes to our business practices and regulatory scrutiny, enforcement or restrictions which, individually or in the aggregate, could have a material adverse effect on our reputation, results of operations, cash flows, financial position, ability to offer certain products and business and prospects generally.

Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities TCF's common stock trades on the New York Stock Exchange under the symbol "TCF." As of February 20, 2018, there were 5,438 holders of record of TCF's common stock. The high and low prices and the dividends declared for TCF's common stock were as follows: 2017: Fourth Quarter Third Quarter Second Quarter First Quarter 2016: Fourth Quarter Third Quarter Second Quarter First Quarter High Low Dividends Declared $ $ 21.29 $ 16.71 $ 17.20 17.47 20.03 14.58 14.89 15.33 19.97 $ 13.73 $ 14.78 14.48 13.97 11.72 11.62 10.37 0.075 0.075 0.075 0.075 0.075 0.075 0.075 0.075 The Board of Directors of TCF Financial and TCF Bank have each adopted a Capital Adequacy and Dividend Policy. The policies define how enterprise risk related to capital will be managed, how the adequacy of capital will be measured and the process by which capital strategy, capital management and preferred and common stock dividend recommendations will be presented to TCF's Board of Directors. TCF management is charged with ensuring that capital strategy actions, including the declaration of preferred and common stock 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, risk profile and overall financial condition. The Board of Directors intends to continue its practice of paying quarterly cash dividends on TCF's common stock as justified by the financial condition of TCF. The declaration and amount of future dividends will depend on circumstances existing at the time, including TCF's earnings, level of internally generated common capital excluding earnings, financial condition and capital requirements, the cash available to pay such dividends (derived mainly from dividends and distributions from TCF Bank), as well as regulatory and contractual limitations and such other factors as the Board of Directors may deem relevant. Dividends for the current dividend period on all outstanding shares of preferred stock must be declared and paid or declared and a sum sufficient for the payment thereof must be set aside before any dividend may be declared or paid on TCF's common stock. In general, TCF Bank may not declare or pay a dividend to TCF Financial in excess of 100% of its net retained earnings for the current year combined with its net retained earnings for the preceding two calendar years without prior approval of the OCC. Restrictions on the ability of TCF Bank to pay cash dividends or possible diminished earnings of TCF may limit the ability of TCF Financial to pay dividends in the future to holders of its preferred and common stock. In addition, the ability of TCF Financial and TCF Bank to pay dividends depends on regulatory policies and capital requirements and may be subject to regulatory approval. See "Item 1. Business - Regulation - Regulatory Capital Requirements", "Item 1. Business - Regulation - Restrictions on Distributions", Note 16. Regulatory Capital Requirements and Note 25.

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. This plan has been replaced by the current share repurchase authorization approved and announced on November 27, 2017. (2) Represents restricted stock withheld pursuant to the terms of awards granted under either the TCF Financial Incentive Stock Program or the TCF Financial 2015 Omnibus Incentive Plan to offset tax withholding obligations that occur upon vesting and release of restricted stock. Both plans provide that the value of shares withheld shall be the average of the high and low prices of common stock of TCF Financial Corporation on the date the relevant transaction occurs. The current share repurchase authorization was approved by the Board of Directors and announced in a press release on November 27, 2017. The authorization was for a repurchase of up to $150.0 million in aggregate value of shares of TCF's common stock. Future repurchases will be based on market conditions, the trading price of TCF shares and other factors. The ability to repurchase shares in the future may be adversely affected by new legislation or regulations or by changes in regulatory policies. This authorization may be commenced or suspended at any time or from time to time. (3) 20 Item 6.

Risk Factors," "Item 6. Selected Financial Data" and "Item 8. Consolidated Financial Statements." Overview TCF Financial Corporation (together with its direct and indirect subsidiaries, "we," "us," "our," "TCF" or the "Company"), a Delaware corporation, is a national bank holding company based in Wayzata, Minnesota. References herein to "TCF Financial" or the "Holding Company" refer to TCF Financial Corporation on an unconsolidated basis. Its principal subsidiary, TCF National Bank ("TCF Bank"), is headquartered in Sioux Falls, South Dakota. At December 31, 2017, TCF had 320 bank branches in Illinois, Minnesota, Michigan, Colorado, Wisconsin, Arizona and South Dakota (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 select locations open seven days a week with extended hours and on most holidays, full-service supermarket branches, access to automated teller machine ("ATM") networks and digital banking channels. TCF's philosophy is to generate interest income, fees and other revenue growth through business lines that emphasize higher yielding assets and low interest cost deposits. TCF's growth strategies include organic growth in existing businesses, development of new products and services, new customer acquisition and acquisitions of portfolios or businesses. New products and services are designed to build on existing businesses and expand into complementary products and services through strategic initiatives. Funded generally through retail deposit generation, TCF continues to focus on profitable asset growth. Net interest income, the difference between interest income earned on loans and leases, securities, investments and other interest-earning assets (interest income) and interest paid on deposits and borrowings (interest expense), represented 67.4% of TCF's total revenue for 2017, compared with 64.5% and 65.0% for 2016 and 2015, respectively. Net interest income can change significantly from period to period based on interest rates, customer prepayment patterns, the volume and mix of interest-earning assets and the volume and mix of interest-bearing and non-interest bearing deposits and interest-bearing borrowings. TCF manages the risk of changes in interest rates on its net interest income through a management Asset & Liability Committee and through related interest rate risk monitoring and management policies. See "Part I, Item 1A. Risk Factors" and "Part II, Item 7A. Quantitative and Qualitative Disclosures about Market Risk" for further discussion. Non-interest income is a significant source of revenue for TCF and an important component of TCF's results of operations. The significant components of non-interest income are from leasing and equipment finance and fees and service charges. The leasing and equipment finance business generates non-interest income primarily from operating leases and sales-type leases. Providing a wide range of consumer banking services is an integral component of TCF's business philosophy. Primary drivers of bank fees and service charges include the number of customers we attract, the customers' level of engagement and the frequency with which the customer uses our solutions. As an effort to diversify TCF's non-interest income sources and manage credit concentration risk, TCF sells loans, primarily in consumer real estate, which result in gains on sales, as well as servicing fee income. Primary drivers of gains on sales include TCF's ability to originate loans held for sale, identify loan buyers and execute loan sales. TCF implemented changes to its auto finance business strategy in 2017, transitioning from a partial reliance on gains on sales of loans to an entirely originate-to-hold model effective April 1, 2017 and discontinued auto finance loan originations effective December 1, 2017. Over time, this shift may decrease capital and operational risk and will impact net interest income, provision for credit losses, gains on sales of auto loans and servicing fee income. 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 2017, 2016 and 2015 and on information about TCF's financial condition, loan and lease portfolio, liquidity, funding resources, capital and other matters. 23 Results of Operations Performance Summary TCF reported diluted earnings per common share of $1.44 for 2017, compared with $1.15 and $1.07 for 2016 and 2015, respectively. TCF reported net income of $268.6 million for 2017, compared with $212.1 million and $197.1 million for 2016 and 2015, respectively. Net income increased $56.5 million, or 26.6%, in 2017 and increased $15.0 million, or 7.6%, in 2016. The increase in net income in 2017 was primarily due to the enactment of the Tax Cuts and Jobs Act ("Tax Reform") on December 22, 2017, partially offset by charges related to the changes implemented to auto finance's business strategy in 2017. As a result of the enactment of Tax Reform, an estimated net tax benefit of $130.7 million, or 77 cents per common share, was recorded for 2017 resulting primarily from the re-measurement of the Company's estimated net deferred tax liability. Effective April 1, 2017, the Company executed its strategic shift from an originate-to-sell and originate-to-hold model to an entirely originate-to-hold model for its auto finance business and effective December 1, 2017, the Company discontinued auto finance loan originations. The determination was based on management's review of strategic alternatives and the financial outlook of the auto finance loan origination business compared with alternative uses of capital. TCF's subsidiary, Gateway One Lending & Finance, LLC, will continue to service existing auto loans on its balance sheet and those serviced for others. The decision to discontinue auto finance loan originations resulted in a goodwill impairment charge of $73.0 million, an other intangible assets impairment charge of $0.4 million and approximately $14.8 million of expenses related to severance, other asset impairments and lease termination expenses in 2017. These auto finance items reduced diluted earnings per common share by 49 cents for 2017. The increase in net income in 2016 was primarily due to revenue growth outpacing expenses. Return on average assets on a fully tax-equivalent basis was 1.26% for 2017, compared with 1.05% and 1.03% for 2016 and 2015, respectively. The return on average assets on a fully tax-equivalent basis increased in 2017 and 2016 primarily due to increases in net income. Total average assets were $22.1 billion for 2017, compared with $21.1 billion and $19.9 billion for 2016 and 2015, respectively. Total average assets increased $976.6 million, or 4.6%, in 2017 and increased $1.2 billion, or 6.0%, in 2016. Return on average common equity was 10.80% for 2017, compared with 9.13% and 9.19% for 2016 and 2015, respectively. The return on average common equity ratio increased in 2017 primarily due to an increase in net income available to common stockholders. The return on average common equity ratio decreased in 2016 primarily due to higher average total common equity. Total average common equity was $2.2 billion for 2017, compared with $2.1 billion and $1.9 billion for 2016 and 2015, respectively. Total average common equity increased $139.0 million, or 6.6%, in 2017 and increased $175.5 million, or 9.1%, in 2016. 24 Consolidated Income Statement Analysis Net Interest Income  Net interest income represented 67.4% of TCF's total revenue for 2017, compared with 64.5% and 65.0% for 2016 and 2015, respectively. Net interest income was $925.2 million for 2017, compared with $848.1 million and $820.4 million for 2016 and 2015, respectively. Net interest income increased $77.1 million, or 9.1%, in 2017 and $27.7 million, or 3.4%, in 2016. The average yield on interest-earning assets on a fully tax-equivalent basis was 5.00%, 4.76% and 4.80% for 2017, 2016 and 2015, respectively. Average interest-earning assets increased $898.2 million, or 4.5%, in 2017 and $1.1 billion, or 6.0%, in 2016. The average rate on interest-bearing liabilities was 0.61%, 0.56% and 0.51% for 2017, 2016 and 2015, respectively. Average interest-bearing liabilities increased $564.2 million, or 3.8%, in 2017 and $667.7 million, or 4.7%, in 2016. The increase in net interest income in 2017 was primarily due to an increase in interest income on loans and leases, partially offset by a decrease in interest income on loans held for sale and an increase in total interest expense. Total interest income was $1.0 billion for 2017, compared with $930.7 million for 2016. Total interest income increased $88.3 million, or 9.5%, in 2017 primarily due to higher average balances and increased average yields on commercial loans, increased average yields on auto finance loans, higher average balances and increased average yields on inventory finance loans and higher average balances of leasing and equipment finance loans and leases. These increases were partially offset by lower average balances of consumer real estate loans. Total interest expense was $93.8 million for 2017, compared with $82.6 million for 2016. Total interest expense increased $11.2 million, or 13.5%, in 2017 primarily due to higher average balances of long-term borrowings and increased average rates and higher average balances of certificates of deposit, partially offset by lower average rates on money market accounts. The increase in net interest income in 2016 was primarily due to an increase in interest income on loans and leases, securities available for sale and loans held for sale, partially offset by an increase in interest expense on deposits. Total interest income was $930.7 million for 2016, compared with $891.9 million for 2015. Total interest income increased $38.8 million, or 4.4%, in 2016 primarily due to higher average balances of loans and leases and securities available for sale, partially offset by a lower average yield on interest-earning assets. Total interest expense was $82.6 million for 2016, compared with $71.5 million for 2015. Total interest expense increased $11.1 million, or 15.5%, in 2016 primarily due to higher interest expense on certificates of deposit due to growth and higher rates paid as a result of special campaigns to fund interest-earning asset growth. Net interest income on a fully tax-equivalent basis divided by average interest-earning assets is referred to as the net interest margin, expressed as a percentage. Net interest income and net interest margin are affected by (i) changes in prevailing short- and long-term interest rates, (ii) loan and deposit pricing strategies and competitive conditions, (iii) the volume and mix of interest-earning assets, non-interest bearing deposits and interest-bearing liabilities, (iv) the level of non-accrual loans and leases and other real estate owned and (v) the impact of modified loans and leases. Net interest margin was 4.54% for 2017, compared with 4.34% and 4.42% for 2016 and 2015, respectively. Net interest margin increased 20 basis points in 2017 and decreased 8 basis points in 2016. The increase in 2017 was primarily due to overall margin expansion on loans and leases, primarily impacted by interest rate increases, partially offset by higher average rates on higher average balances of certificates of deposit. The decrease in 2016 was primarily due to margin compression resulting from the competitive, low interest rate environment and higher rates on certificates of deposit. 25   TCF's average balances, interest, and yields and rates on major categories of TCF's interest-earning assets and interest-bearing liabilities on a fully tax-equivalent basis were as follows: Year Ended December 31, 2017 2016 Change Average Balance Interest(1) Yields and Rates(1) Average Balance Interest(1) Yields and Rates(1) Average Balance Interest Yields and Rates (bps) (Dollars in thousands) Assets: Investments and other $ 282,507 $ 10,491 3.71% $ 319,582 $ 170,006 4,436 2.61 190,863 Securities held to maturity Securities available for sale:(2) Taxable Tax-exempt(3) Loans and leases held for sale Loans and leases:(4) Consumer real estate: Fixed-rate Variable- and adjustable-rate Total consumer real estate Commercial: Fixed-rate Variable- and adjustable-rate Total commercial Leasing and equipment finance Inventory finance Auto finance Other 823,526 712,530 208,678 18,382 22,916 16,606 1,934,395 2,961,449 4,895,844 977,698 2,455,578 3,433,276 4,399,138 2,646,500 3,105,326 11,149 109,185 171,671 280,856 47,587 111,886 159,473 202,508 164,386 152,974 571 Total loans and leases 18,491,233 960,768 Total interest-earning assets 20,688,480 1,033,599 Other assets(5) Total assets Liabilities and Equity: Non-interest bearing deposits: Retail Small business Commercial and custodial 1,363,487 $ 22,051,967 $ 1,931,856 925,890 634,487 Total non-interest bearing deposits 3,492,233 Interest-bearing deposits: Checking Savings Money market Certificates of deposit Total interest-bearing deposits Total deposits Borrowings: Short-term borrowings Long-term borrowings Total borrowings 2,541,407 4,888,280 2,140,553 4,495,062 14,065,302 17,557,535 5,267 1,239,433 1,244,700 Total interest-bearing liabilities 15,310,002 Total deposits and borrowings 18,802,235 Accrued expenses and other liabilities 713,794 Total liabilities 19,516,029 Total TCF Financial Corp. stockholders' equity Non-controlling interest in subsidiaries Total equity 2,513,424 22,514 2,535,938 Total liabilities and equity $ 22,051,967 379 4,255 10,139 51,239 66,012 66,012 58 27,749 27,807 93,819 93,819 2.23 3.22 7.96 5.64 5.80 5.74 4.87 4.56 4.64 4.60 6.21 4.93 5.11 5.20 5.00 0.01 0.09 0.47 1.14 0.47 0.38 1.10 2.24 2.23 0.61 0.50 719,743 495,708 479,401 2,285,647 2,948,482 5,234,129 972,107 2,154,774 3,126,881 4,106,718 2,414,684 2,693,041 9,538 17,584,991 19,790,288 1,285,127 $ 21,075,415 $ 1,778,707 884,192 585,611 3,248,510 2,452,206 4,677,517 2,488,977 4,229,247 13,847,947 17,096,457 7,051 890,846 897,897 14,745,844 17,994,354 686,360 18,680,714 2,373,176 21,525 2,394,701 $ 21,075,415 80 17 (3) 1 (31) (8) 48 24 (1) 57 37 14 39 82 (63) 33 24 — 6 (14) 8 2 2 37 (9) (9) 5 4 9,314 4,649 16,238 15,900 39,648 130,753 156,919 287,672 47,445 85,996 133,441 183,029 140,453 110,651 548 855,794 941,543 346 1,510 15,114 44,818 61,788 61,788 51 20,785 20,836 82,624 82,624 2.91% $ (37,075) $ 1,177 2.44 (20,857) (213) 2.26 3.21 8.27 5.72 5.32 5.50 4.88 3.99 4.27 4.46 5.82 4.11 5.74 4.87 4.76 0.01 0.03 0.61 1.06 0.45 0.36 0.73 2.33 2.32 0.56 0.46 103,783 216,822 2,144 7,016 (270,723) (23,042) (351,252) (21,568) 12,967 (338,285) 14,752 (6,816) 142 25,890 26,032 19,479 23,933 42,323 23 104,974 92,056 33 2,745 (4,975) 6,421 4,224 4,224 7 6,964 6,971 11,195 11,195 5,591 300,804 306,395 292,420 231,816 412,285 1,611 906,242 898,192 78,360 $ 976,552 $ 153,149 41,698 48,876 243,723 89,201 210,763 (348,424) 265,815 217,355 461,078 (1,784) 348,587 346,803 564,158 807,881 27,434 835,315 140,248 989 141,237 $ 976,552 Net interest income and margin $ 939,780 4.54 $ 858,919 4.34 $ 80,861 20 (1) (2) (3) (4) (5) Interest and yields are presented on a fully tax-equivalent basis.

Includes leased equipment and related initial direct costs under operating leases of $140.3 million and $104.1 million for 2016 and 2015, respectively. 27 The components of the changes in net interest income on a fully tax-equivalent basis by volume and rate were as follows: Year Ended December 31, 2017 December 31, 2016 Versus December 31, 2016 Versus December 31, 2015 (In thousands) Interest income: Investments and other Securities held to maturity Securities available for sale: Taxable Tax-exempt Loans and leases held for sale Loans and leases: Consumer real estate: Fixed-rate Variable- and adjustable-rate Total consumer real estate Commercial: Fixed-rate Variable- and adjustable-rate Total commercial Leasing and equipment finance Inventory finance Auto finance Other Total loans and leases Total interest income Interest expense: Deposits: Checking Savings Money market Certificates of deposit Total deposits Borrowings: Short-term borrowings Long-term borrowings Total borrowings Total interest expense Net interest income Increase (Decrease) Due to Rate(1) Volume(1) Total Increase (Decrease) Due to Rate(1) Volume(1) Total $ (1,166) $ 2,343 $ 1,177 $ (5,442) $ 2,462 $ (2,980) (530) 317 (213) (415) (422) (837) 2,318 6,974 (174) 42 2,144 7,016 (21,553) (1,489) (23,042) 3,588 13,306 16,026 (1,280) (49) (2,144) 2,308 13,257 13,882 (19,589) (1,979) (21,568) (24,650) (2,025) (26,675) 715 (18,630) 14,037 11,814 14,752 1,795 (6,816) (22,030) 5,354 2,504 7,149 (19,526) 360 13,001 13,913 13,326 14,284 18,588 88 46,284 44,754 (218) 142 (9,963) (1,629) (11,592) 12,889 12,119 6,153 9,649 23,735 (65) 58,690 47,302 25,890 26,032 19,479 23,933 42,323 23 104,974 92,056 7,496 (378) 13,635 14,769 16,747 (50) 26,962 52,032 1,823 (1,895) (6,171) 2,885 (559) (114) (7,619) (7,059) 9,319 (2,273) 7,464 17,654 16,188 (164) 19,343 44,973 14 72 19 2,673 33 2,745 12 (213) (201) (152) (1,343) (1,495) (1,924) (3,051) (4,975) 2,979 1,768 (15) 7,862 7,801 3,310 3,442 2,456 22 (898) (830) 6,421 4,224 7 6,964 6,971 7,885 11,195 1,342 8,843 3,620 (48) (5,116) (5,327) 3,447 (465) 5,538 9,942 46 2,638 2,847 7,635 877 14,381 13,562 (2) (2,478) (2,480) 11,082 $ 40,815 $ 40,046 $ 80,861 $ 47,783 $ (13,892) $ 33,891 (1) Changes attributable to the combined impact of volume and rate have been allocated proportionately to the change due to volume and the change due to rate. Changes due to volume and rate are calculated independently for each line item presented. 28 Provision for Credit Losses  The provision for credit losses is calculated as part of the determination of the allowance for loan and lease losses, which is a critical accounting estimate. TCF's evaluation of incurred losses is based upon historical loss rates multiplied by the respective portfolio's loss emergence period. Factors utilized in the determination and allocation of the allowance for loan and lease losses and the related provision for credit losses include historical trends in loss rates, a portfolio's overall risk characteristics, changes in its character or size, risk rating migration, delinquencies, collateral values, economic outlook and prevailing economic conditions. The composition of TCF's provision for credit losses was as follows: (Dollars in thousands) 2017 2016 2015 2017 / 2016 2016 / 2015 Consumer real estate $(12,318) (18.0)% $ 9,304 14.1% $ 12,697 24.0% $(21,622) N.M. $ (3,393) (26.7)% Commercial 9,098 13.3 2,890 4.4 298 0.6 6,208 N.M. 2,592 N.M.

The provision for credit losses increased $2.6 million, or 3.9%, in 2017 and $12.9 million, or 24.4%, in 2016. The increase in the provision for credit losses in 2017 was primarily due to increased provision for credit losses related to the auto finance, commercial and leasing and equipment finance portfolios, partially offset by a decrease in provision for credit losses related to the consumer real estate portfolio. The increase in the provision for credit losses related to the auto finance portfolio was primarily due to increased net charge-offs and growth as a result of the reclassification of loans from held for sale to held for investment. The increase in the provision for credit losses related to the commercial and leasing and equipment finance portfolios was primarily due to increased net charge- offs. The decrease in the provision for credit losses related to the consumer real estate portfolio was primarily due to the recovery of $13.3 million on previous charge-offs related to the non-accrual loans that were sold in the first and third quarters of 2017 and improving credit quality. The increase in the provision for credit losses in 2016 was primarily due to the benefit from reduced reserves in 2015 (the allowance as a percent of total loans and leases was 0.90% and 1.00% at December 31, 2015 and 2014, respectively) and growth in the overall loan and lease portfolio, partially offset by decreased net charge-offs. For further information, see "Consolidated Financial Condition Analysis — Credit Quality" in this Management's Discussion and Analysis and Note 7. Allowance for Loan and Lease Losses and Credit Quality Information of Notes to Consolidated Financial Statements. 29 Non-interest Income  Non-interest income is a significant source of revenue for TCF, representing 32.6% of total revenue for 2017, compared with 35.5% and 35.0% for 2016 and 2015, respectively, and is an important factor in TCF's results of operations. Non-interest income was $448.3 million for 2017, compared with $465.9 million and $442.0 million for 2016 and 2015, respectively. Non-interest income decreased $17.6 million, or 3.8%, in 2017 and increased $23.9 million, or 5.4%, in 2016. The decrease in 2017 was primarily due to decreases in net gains on sales of auto loans, net gains on sales of consumer real estate loans and fees and service charges, partially offset by an increase in leasing and equipment finance non-interest income. The increase in 2016 was primarily due to increases in leasing and equipment finance non-interest income, net gains on sales of consumer real estate loans, servicing fee income and net gains on sales of auto loans, partially offset by a decrease in fees and service charges. The components of non-interest income were as follows: (Dollars in thousands) Fees and service charges Card revenue ATM revenue Subtotal Gains on sales of auto loans, net Gains on sales of consumer real estate loans, net Servicing fee income Subtotal Leasing and equipment finance Other Fees and other revenue Gains (losses) on securities, net Total non-interest income Year Ended December 31, Change 2017 2016 2015 2017 / 2016 2016 / 2015 $ 131,887 $ 137,664 $ 144,999 (4.2)% (5.1)% 55,732 19,624 207,243 5,460 37,327 41,347 84,134 145,039 11,646 448,062 237 54,882 20,445 212,991 34,832 50,427 40,182 125,441 119,166 8,883 466,481 54,387 21,544 220,930 30,580 40,964 31,229 102,773 108,129 10,463 442,295 (581) (297) $ 448,299 $ 465,900 $ 441,998 1.5 (4.0) (2.7) (84.3) (26.0) 2.9 (32.9) 21.7 31.1 (3.9) N.M.

Fees and Service Charges  Fees and service charges totaled $131.9 million for 2017, compared with $137.7 million and $145.0 million for 2016 and 2015, respectively. Fees and service charges decreased $5.8 million, or 4.2%, in 2017 and $7.3 million, or 5.1%, in 2016 primarily due to ongoing consumer behavior changes, as well as higher average checking account balances per customer. Gains on Sales of Auto Loans, Net  Net gains on sales of auto loans totaled $5.5 million for 2017, compared with $34.8 million and $30.6 million for 2016 and 2015, respectively. Net gains on sales of auto loans decreased $29.4 million, or 84.3%, in 2017 and increased $4.3 million, or 13.9%, in 2016. The decrease in 2017 was primarily due to the strategic shift in auto finance. The increase in 2016 was primarily due to increased volume of loans sold, partially offset by a strong competitive environment and challenging market conditions. TCF sold $424.7 million, $2.1 billion and $1.3 billion of auto loans in 2017, 2016 and 2015, respectively. See Note 6. Loans and Leases of Notes to Consolidated Financial Statements for further information. Gains on Sales of Consumer Real Estate Loans, Net  Net gains on sales of consumer real estate loans totaled $37.3 million for 2017, compared with $50.4 million and $41.0 million for 2016 and 2015, respectively. Net gains on sales of consumer real estate loans decreased $13.1 million, or 26.0%, in 2017 and increased $9.5 million, or 23.1%, in 2016. The decrease in 2017 was primarily due to decreased volume of loans sold. The increase in 2016 was primarily due to increased volume of loans sold. TCF sold $1.3 billion, $1.6 billion and $1.3 billion of consumer real estate loans in 2017, 2016 and 2015, respectively. See Note 6. Loans and Leases of Notes to Consolidated Financial Statements for further information. 30 Servicing Fee Income  Servicing fee income totaled $41.3 million for 2017, compared with $40.2 million and $31.2 million for 2016 and 2015, respectively. Of this amount, $33.6 million relates to auto finance loans serviced for others for 2017, compared with $33.1 million and $24.1 million for 2016 and 2015, respectively, and $6.4 million relates to consumer real estate loans serviced for others for 2017, compared with $5.4 million and $5.0 million for 2016 and 2015, respectively. Servicing fee income increased $9.0 million, or 28.7%, in 2016 primarily due to the cumulative effect of the increases in the portfolios of auto finance and consumer real estate loans sold with servicing retained by TCF. Average auto finance loans serviced for others were $2.5 billion for 2017, compared with $2.6 billion and $2.0 billion for 2016 and 2015, respectively. Average consumer real estate loans serviced for others were $2.4 billion for 2017, compared with $2.0 billion and $1.6 billion for 2016 and 2015, respectively. Leasing and Equipment Finance Leasing and equipment finance non-interest income totaled $145.0 million for 2017, compared with $119.2 million and $108.1 million for 2016 and 2015, respectively. Leasing and equipment finance non- interest income increased $25.9 million, or 21.7%, in 2017 and $11.0 million, or 10.2%, in 2016. The increase in 2017 was primarily due to an increase in operating lease revenue, mainly driven by the acquisition of Equipment Financing & Leasing Corporation ("EFLC") in the second quarter of 2017 and portfolio growth. The increase in 2016 was primarily due to higher operating lease and sales-type lease revenue. Non-interest Expense  Non-interest expense totaled $1.1 billion for 2017, compared with $909.9 million and $894.7 million for 2016 and 2015, respectively. Non-interest expense increased $150.0 million, or 16.5%, in 2017 and $15.1 million, or 1.7%, in 2016. The increase in 2017 was primarily due to increases in other non-interest expense, operating lease depreciation, compensation and employee benefits expense, occupancy and equipment expense and net foreclosed real estate and repossessed assets expense. The increase in 2016 was primarily due to increases in compensation and employee benefits expense, occupancy and equipment expense and other non-interest expense, partially offset by a decrease in net foreclosed real estate and repossessed assets expense. The components of non-interest expense were as follows: (Dollars in thousands) 2017 2016 2015 2017 / 2016 2016 / 2015 Compensation and employee benefits $ 483,235 $ 474,722 $ 457,743 1.8% 3.7% Year Ended December 31, Change Occupancy and equipment Other Subtotal Operating lease depreciation Foreclosed real estate and repossessed assets, net Other credit costs, net Total non-interest expense N.M.

Compensation and employee benefits expense increased $8.5 million, or 1.8%, in 2017 and $17.0 million, or 3.7%, in 2016. The increase in 2017 was primarily due to higher enterprise services contract labor utilization, higher incentive compensation and one-time employee bonuses, partially offset by reduced headcount in auto finance resulting in lower salaries and commissions. The increase in 2016 was primarily due to higher commissions and incentives, partially offset by the annual pension plan valuation adjustment. Occupancy and Equipment Occupancy and equipment expense totaled $156.9 million for 2017, compared with $150.0 million and $145.0 million for 2016 and 2015, respectively. Occupancy and equipment expense increased $6.9 million, or 4.6%, in 2017 and $5.0 million, or 3.5%, in 2016. The increase in 2017 was primarily due to increased software maintenance expense and ATM expenses, partially offset by lower repairs and maintenance. The increase in 2016 was primarily due to increased depreciation and amortization expense and higher software maintenance expense. Depreciation and amortization expense related to premises and equipment was $45.9 million, $44.9 million and $40.8 million in 2017, 2016 and 2015, respectively. 31 Other Non-interest Expense Other non-interest expense totaled $345.5 million for 2017, compared with $231.4 million and $229.3 million for 2016 and 2015, respectively. Other non-interest expense increased $114.0 million, or 49.3%, in 2017 and $2.2 million, or 0.9%, in 2016. The increase in 2017 was primarily due to charges related to the discontinuation of auto finance loan originations, including goodwill and other intangible assets impairment charges of $73.4 million and severance, asset impairment and lease termination expenses of $14.8 million, increased professional fees of $13.7 million driven by strategic investments in technology capabilities, a $6.3 million increase in charitable contributions related to the additional donation to TCF Foundation of $5.0 million, a $5.2 million increase in outside processing expense, a $4.7 million increase in advertising and marketing expense and a $2.5 million increase in card processing expense, partially offset by a $4.0 million decrease in loan and lease processing expense and a $3.0 million decrease in branch realignment expense. The increase in 2016 was primarily due to $3.9 million of branch realignment expense related to the closure of two traditional branches and 50 supermarket branches, a $1.6 million increase in loan and lease processing expense due to increases in loan and lease originations and a $1.0 million increase in outside processing expense, partially offset by a $4.4 million decrease in Federal Deposit Insurance Corporation ("FDIC") insurance expense due to a lower assessment rate. See Note 23. Other Non-interest Expense of Notes to Consolidated Financial Statements for further information. Operating Lease Depreciation Operating lease depreciation totaled $55.9 million for 2017, compared with $40.4 million and $39.4 million for 2016 and 2015, respectively. Operating lease depreciation increased $15.5 million, or 38.5%, in 2017 primarily due to more transactions resulting in part from the acquisition of EFLC. Foreclosed Real Estate and Repossessed Assets, Net  Net foreclosed real estate and repossessed assets expense totaled $17.8 million for 2017, compared with $13.2 million and $23.2 million for 2016 and 2015, respectively. Net foreclosed real estate and repossessed assets expense increased $4.6 million, or 34.6%, in 2017 and decreased $10.0 million, or 43.1%, in 2016. The increase in 2017 was due to higher repossessed assets expense primarily attributable to auto finance and lower gains on sales of commercial properties, partially offset by lower operating costs associated with maintaining fewer consumer properties. The decrease in 2016 was primarily due to lower operating costs associated with maintaining fewer properties, lower write-downs on existing foreclosed commercial and consumer properties and higher gains on sales of commercial and consumer properties, partially offset by higher repossessed assets expense. Income Taxes  Income tax benefit was $33.6 million for 2017, compared with income tax expense of $116.5 million and $108.9 million for 2016 and 2015, respectively. The income tax benefit for 2017 was impacted by an estimated net tax benefit of $130.7 million primarily resulting from the re-measurement of the Company's estimated net deferred tax liability as a result of the enactment of Tax Reform. See Note 2. Summary of Significant Accounting Policies and Note 14. Income Taxes of Notes to Consolidated Financial Statements for further information. 32 Reportable Segment Results The Company's reportable segments are Consumer Banking, Wholesale Banking and Enterprise Services. See Note 24. Business Segments of Notes to Consolidated Financial Statements for further information regarding net income (loss), assets and revenues for each of TCF's reportable segments. Consumer Banking Consumer Banking is comprised of all of the Company's consumer-facing businesses and includes retail banking, consumer real estate and auto finance. TCF's consumer banking strategy is primarily to originate high credit quality secured consumer real estate loans for investment and for sale and to generate deposits. Effective April 1, 2017, the Company executed its strategic shift from an originate-to-sell and originate-to-hold model to an entirely originate-to- hold model for its auto finance business and effective December 1, 2017, the Company discontinued auto finance loan originations. TCF will continue to service existing auto loans on its balance sheet and those serviced for others. Deposits are generated from consumers and small businesses to provide a source of low cost funds, with a focus on building and maintaining quality customer relationships. The Consumer Banking reportable segment generates a significant portion of the Company's net interest income and non-interest income from fees and service charges, card revenue, ATM revenue, gains on sales of loans and servicing fee income, and incurs a significant portion of the Company's provision for credit losses and non-interest expense. Consumer Banking generated net income available to common stockholders of $23.1 million for 2017, compared with $124.0 million and $105.5 million for 2016 and 2015, respectively. Consumer Banking net income available to common stockholders decreased $100.9 million, or 81.3%, in 2017 and increased $18.6 million, or 17.6%, in 2016. Consumer Banking net interest income totaled $574.6 million for 2017, compared with $559.9 million and $536.7 million for 2016 and 2015, respectively. Net interest income increased $14.8 million, or 2.6%, in 2017 and $23.1 million, or 4.3%, in 2016. The increase in 2017 was primarily due to an increase in interest income on loans and an increase in funds transfer pricing credits, partially offset by a decrease in interest income on loans held for sale and an increase in total interest expense. The increase in 2016 was primarily due to an increase in interest income related to funds transfer pricing credits and an increase in interest income on loans held for sale, partially offset by an increase in total interest expense. Total interest income attributable to the Consumer Banking segment was $823.5 million for 2017, compared with $796.1 million and $755.3 million for 2016 and 2015, respectively. Total interest income increased $27.4 million, or 3.4%, in 2017 and $40.7 million, or 5.4%, in 2016. The increase in total interest income in 2017 was primarily due to higher average yields on auto finance loans and an increase in funds transfer pricing credits driven by deposits, partially offset by lower average balances of consumer real estate loans. The increase in total interest income in 2016 was primarily due to an increase in funds transfer pricing credits driven by an increase in deposits and higher average balances of auto finance loans, partially offset by a decrease in interest income from consumer real estate first mortgage lien loan balances due to run-off. Total interest expense attributable to the Consumer Banking segment was $248.9 million for 2017, compared with $236.2 million and $218.6 million for 2016 and 2015, respectively. Total interest expense increased $12.7 million, or 5.4%, in 2017 and $17.6 million, or 8.1%, in 2016. The increase in total interest expense in 2017 was primarily due to an increase in interest expense on inter-company borrowings and an increase in funds transfer pricing charges.The increase in total interest expense in 2016 was primarily due to higher interest expense on certificates of deposits due to growth and higher rates paid as a result of special campaigns to fund loan growth. Consumer Banking provision for credit losses totaled $48.2 million for 2017, compared with $50.8 million and $44.3 million for 2016 and 2015, respectively. The provision for credit losses decreased $2.6 million, or 5.1%, in 2017 and increased $6.5 million, or 14.6%, in 2016. The decrease in the provision for credit losses in 2017 was primarily due to a decreased provision for credit losses related to the consumer real estate portfolio, partially offset by an increased provision for credit losses related to the auto finance portfolio. The decrease in the provision for credit losses related to the consumer real estate portfolio was primarily due to the recovery of $13.3 million on previous charge-offs related to the non-accrual loans that were sold in the first and third quarters of 2017 and improving credit quality. The increase in the provision for credit losses related to the auto finance portfolio was primarily due to increased net charge- offs and growth as a result of the reclassification of loans from held for sale to held for investment. The increase in the provision for credit losses in 2016 was primarily due to the benefit from reduced reserve requirements in 2015 for the consumer real estate portfolio (the allowance for credit losses as a percent of consumer banking loans was 1.19% and 1.18% at December 31, 2016 and 2015, respectively), partially offset by decreased net charge-offs. 33 Consumer Banking non-interest income totaled $290.0 million for 2017, compared with $337.0 million and $320.4 million for 2016 and 2015, respectively. Non-interest income decreased $47.0 million, or 13.9%, in 2017 and increased $16.6 million, or 5.2%, in 2016. The decrease in 2017 was primarily due to decreases in net gains on sales of auto loans, net gains on sales of consumer real estate loans and fees and service charges. The increase in 2016 was primarily due to increases in net gains on sales of consumer real estate loans, net gains on sales of auto loans and servicing fee income, partially offset by a decrease in fees and service charges. Fees and service charges attributable to the Consumer Banking segment totaled $121.7 million for 2017, compared with $130.5 million and $138.7 million for 2016 and 2015, respectively. Fees and service charges decreased $8.8 million, or 6.8%, in 2017 and $8.1 million, or 5.9%, in 2016, primarily due to ongoing consumer behavior changes, as well as higher average checking account balances per customer. Net gains on sales of auto loans totaled $5.5 million for 2017, compared with $34.8 million and $30.6 million for 2016 and 2015, respectively. Net gains on sales of auto loans decreased $29.4 million, or 84.3%, in 2017 and increased $4.3 million, or 13.9%, in 2016. The decrease in 2017 was due to the strategic shift in auto finance. The increase in 2016 was primarily due to increased volume of loans sold, partially offset by a strong competitive environment and challenging market conditions. Net gains on sales of consumer real estate loans totaled $37.3 million for 2017, compared with $50.4 million and $41.0 million for 2016 and 2015, respectively. Net gains on sales of consumer real estate loans decreased $13.0 million, or 25.9%, in 2017 and increased $9.4 million, or 23.0%, in 2016. The decrease in 2017 was primarily due to decreased volume of loans sold. The increase in 2016 was primarily due to increased volume of loans sold. Servicing fee income attributable to the Consumer Banking segment totaled $40.0 million for 2017, compared with $38.6 million and $29.0 million for 2016 and 2015, respectively. Of this amount, $33.6 million relates to auto finance loans serviced for others for 2017, compared with $33.1 million and $24.1 million for 2016 and 2015, respectively, and $6.4 million relates to consumer real estate loans serviced for others for 2017, compared with $5.4 million and $5.0 million for 2016 and 2015, respectively. Servicing fee income increased $9.5 million, or 32.9%, in 2016 due to the cumulative effect of the increases in the portfolios of auto finance and consumer real estate loans sold with servicing retained by TCF. Average auto finance loans serviced for others were $2.5 billion for 2017, compared with $2.6 billion and $2.0 billion for 2016 and 2015, respectively. Average consumer real estate loans serviced for others were $2.4 billion for 2017, compared with $2.0 billion and $1.6 billion for 2016 and 2015, respectively. Consumer Banking non-interest expense totaled $743.7 million for 2017, compared with $652.5 million and $645.9 million for 2016 and 2015, respectively. Non-interest expense increased $91.3 million, or 14.0%, in 2017 and $6.5 million, or 1.0%, in 2016. The increase in 2017 was primarily due to charges related to the discontinuation of auto finance loan originations, including goodwill and other intangible asset impairment charges and severance, asset impairment and lease termination expenses, as well as increases in occupancy and equipment expense, allocation expense from Enterprise Services, advertising and marketing expense, net foreclosed real estate and repossessed assets expense and card processing expense. These increases were partially offset by a decrease in compensation and employee benefits expense attributable to reduced headcount in auto finance resulting in lower salaries and commissions, a decrease in branch realignment expense and a decrease in loan processing expense. The increase in 2016 was primarily due to higher occupancy and equipment expense and branch realignment expense of $3.9 million related to the closure of two traditional branches and 50 supermarket branches. These increases were partially offset by a decrease in net foreclosed real estate and repossessed assets expense due to lower operating costs associated with maintaining fewer consumer properties, higher gains on sales of consumer properties and lower write-downs on existing foreclosed consumer properties, as well as a decrease in FDIC insurance expense due to a lower assessment rate. 34 Wholesale Banking Wholesale Banking is comprised of commercial lending, leasing and equipment finance and inventory finance. TCF's wholesale banking strategy is primarily to originate high credit quality secured loans and leases for investment. Wholesale Banking generated net income available to common stockholders of $278.4 million for 2017, compared with $130.0 million and $127.3 million for 2016 and 2015, respectively. Wholesale Banking net income available to common stockholders increased $148.4 million, or 114.2%, in 2017 and $2.6 million, or 2.1%, in 2016. Wholesale Banking net interest income totaled $359.3 million for 2017, compared with $343.7 million and $339.9 million for 2016 and 2015, respectively. Net interest income increased $15.6 million, or 4.5%, in 2017 and $3.7 million, or 1.1%, in 2016. The increases in both periods were primarily due to increases in interest income on loans and leases, partially offset by increases in total interest expense. Total interest income attributable to the Wholesale Banking segment was $552.8 million for 2017, compared with $479.6 million and $452.8 million for 2016 and 2015, respectively. Total interest income increased $73.2 million, or 15.3%, in 2017 and $26.8 million, or 5.9%, in 2016. The increase in total interest income in 2017 was primarily due to higher average balances and increased average yields on commercial and inventory finance loans and higher average balances of leasing and equipment finance loans and leases. The increase in total interest income in 2016 was primarily due to higher average loan and lease balances in the leasing and equipment finance and inventory finance portfolios. Total interest expense attributable to the Wholesale Banking segment was $193.5 million for 2017, compared with $135.9 million and $112.9 million for 2016 and 2015, respectively. Total interest expense increased $57.6 million, or 42.4%, in 2017 and $23.1 million, or 20.4%, in 2016. The increase in total interest expense in 2017 was primarily due to higher funds transfer pricing charges driven by an increase in loans and leases and an increase in interest expense on inter-company borrowings. The increase in total interest expense in 2016 was primarily due to higher funds transfer pricing charges driven by a combination of higher average loan and lease balances and an increase in funds transfer pricing rates. Wholesale Banking provision for credit losses totaled $20.2 million for 2017, compared with $15.1 million and $8.6 million for 2016 and 2015, respectively. The provision for credit losses increased $5.2 million, or 34.3%, in 2017 and $6.4 million, or 74.7%, in 2016. The increase in 2017 was primarily due to increased net charge-offs in the commercial and leasing and equipment finance portfolios, partially offset by lower reserve requirements in the inventory finance portfolio. The increase in 2016 was primarily due to increased reserve requirements related to overall growth in the Wholesale Banking loan and lease portfolio. Wholesale Banking non-interest income totaled $158.0 million for 2017, compared with $128.9 million and $119.8 million for 2016 and 2015, respectively. Non-interest income increased $29.1 million, or 22.6%, in 2017 and $9.1 million, or 7.6%, in 2016. The increase in 2017 was primarily due to an increase in leasing and equipment finance non-interest income due to an increase in operating lease revenue, mainly driven by the acquisition of EFLC in the second quarter of 2017 and portfolio growth. The increase in 2016 was primarily due to an increase in leasing and equipment finance non-interest income due to higher operating lease and sales-type lease revenue. Wholesale Banking non-interest expense totaled $277.4 million for 2017, compared with $247.1 million and $244.9 million for 2016 and 2015, respectively. Non-interest expense increased $30.3 million, or 12.3%, in 2017 and $2.2 million, or 0.9%, in 2016. The increase in 2017 was primarily due to an increase in operating lease depreciation primarily attributable to more transactions resulting in part from the acquisition of EFLC and an increase in occupancy and equipment expense. The increase in 2016 was primarily due to an increase in allocated costs due to the further build-out of risk management and credit, partially offset by a decrease in compensation and benefits expense, a decrease in net foreclosed real estate and repossessed assets expense due to lower write-downs on existing foreclosed commercial properties and lower operating costs associated with maintaining fewer commercial properties and a decrease in occupancy and equipment expense. 35 Enterprise Services Enterprise Services is comprised of (i) corporate treasury, which includes the Company's investment and borrowing portfolios and management of capital, debt and market risks, (ii) corporate functions, such as information technology, risk and credit management, bank operations, finance, investor relations, corporate development, legal and human capital management, that provide services to the operating segments, (iii) the Holding Company and (iv) eliminations. The Company's investment portfolio accounts for the earning assets within this segment. Borrowings may be used to offset reductions in deposits or to support lending activities. This segment also includes residual revenues and expenses representing the difference between actual amounts incurred by Enterprise Services and amounts allocated to the operating segments, including interest rate risk residuals such as funds transfer pricing mismatches. Enterprise Services generated a net loss available to common stockholders of $58.5 million for 2017, compared with $61.3 million and $55.1 million for 2016 and 2015, respectively. Enterprise Services net loss available to common stockholders decreased $2.7 million, or 4.5%, in 2017 and increased $6.2 million, or 11.2%, in 2016. Enterprise Services net interest expense totaled $8.7 million for 2017, compared with $55.4 million and $56.3 million for 2016 and 2015, respectively. Net interest expense decreased $46.7 million, or 84.4%, in 2017 and $0.9 million, or 1.5%, in 2016. The decrease in 2017 was primarily driven by a decrease in funds transfer pricing mismatches as a result of rising interest rates and an increase in interest income attributable to higher average balances of securities available for sale, partially offset by an increase in interest expense primarily due to higher average balances of long- term borrowings and higher interest expense on deposits. The decrease in 2016 was primarily driven by an increase in interest income attributable to higher average balances of securities available for sale and a decrease in borrowing expense, partially offset by an increase in funds transfer pricing mismatches. Enterprise Services non-interest income totaled $0.3 million for 2017, compared with $28.0 thousand and $1.8 million for 2016 and 2015, respectively. Non-interest income decreased $1.8 million, or 98.5%, in 2016 primarily due to a gain of $1.7 million related to appreciation of an investment that was donated to TCF Foundation in the first quarter of 2015. Enterprise Services non-interest expense totaled $38.8 million for 2017, compared with $10.3 million and $3.9 million for 2016 and 2015, respectively. Non-interest expense increased $28.5 million, or 276.0%, in 2017 and $6.4 million, or 165.3%, in 2016. The increase in 2017 was primarily due to higher compensation and employee benefits expense due to higher contract labor utilization, higher incentive compensation and one-time employee bonuses, as well as higher professional fees related to strategic investments in technology capabilities and higher contribution expense related to the additional donation to TCF Foundation of $5.0 million. These increases were partially offset by a decrease in occupancy and equipment expense. The increase in 2016 was primarily due to an increase in compensation and benefits expense, partially offset by an increase in recoveries of allocated expenses, a decrease in occupancy and equipment expense and the annual pension plan valuation adjustment. Consolidated Financial Condition Analysis Securities Available for Sale and Securities Held to Maturity Total securities available for sale were $1.7 billion at December 31, 2017, an increase of $285.6 million, or 20.1%, from $1.4 billion at December 31, 2016. TCF's securities available for sale portfolio consists primarily of fixed-rate mortgage-backed securities issued by the Federal National Mortgage Association ("Fannie Mae") and obligations of states and political subdivisions. The increase in securities available for sale was primarily due to purchases of obligations of states and political subdivisions and fixed-rate mortgage-backed securities, partially offset by proceeds from maturities and principal collected on fixed-rate mortgage- backed securities. TCF may, from time to time, sell securities available for sale and utilize the proceeds to reduce borrowings, fund growth in loans and leases or for other corporate purposes. There were no sales of securities available for sale during 2017 or 2016. In 2015, TCF sold $0.2 million of securities available for sale. Total securities held to maturity were $161.6 million at December 31, 2017, a decrease of $19.7 million, or 10.9%, from $181.3 million at December 31, 2016. TCF's securities held to maturity portfolio consists primarily of fixed-rate mortgage-backed securities issued by Fannie Mae. The decrease in securities held to maturity was primarily due to proceeds from maturities and principal collected on fixed-rate mortgage-backed securities. 36 The amortized cost, fair value and fully tax-equivalent yield of securities available for sale and securities held to maturity by final contractual maturity were as follows. The remaining contractual principal maturities do not consider possible prepayments. Remaining expected maturities will differ from contractual maturities because borrowers may have the right to prepay. 2017 At December 31, 2016 2015 Amortized Cost Fair Value Tax- equivalent Yield Amortized Cost Fair Value Tax- equivalent Yield Amortized Cost Fair Value Tax- equivalent Yield (Dollars in thousands) Securities available for sale: Mortgage-backed securities: Due in one year or less $ Due in 1-5 years $ 6 — 6 — Due in 5-10 years 82,842 82,046 Due after 10 years Obligations of states and political subdivisions: 825,347 812,639 Due in 1-5 years 15,178 15,312 Due in 5-10 years 431,494 435,821 363,487 363,194 — 2.04 2.32 2.97 3.14 3.29 1.98% $ 1 $ 8.02% $ 1 $ 18 1 18 38 1 38 54,202 54,429 70,338 70,350 2.28 1.93 773,519 756,461 2.25 557,178 551,575 — — 277,228 274,576 351,744 337,950 — 3.13 3.20 — — 198,300 202,161 63,889 64,760 9.00% 2.65 1.93 2.46 — 3.19 3.40 Due after 10 years Total securities available for sale Securities held to maturity: Mortgage-backed securities: Due after 10 years Other securities: Due in one year or less Due in 1-5 years Due in 5-10 years Total securities held to maturity $1,718,354 $1,709,018 2.72 $1,456,712 $1,423,435 2.63 $ 889,744 $ 888,885 2.65 $ 158,776 $ 162,826 2.55% $ 178,514 $ 181,146 2.54% $ 198,520 $ 203,553 2.64% 1,000 1,400 400 1,000 1,400 400 3.00 3.21 3.00 — 1,400 1,400 — 1,400 1,400 — 2.86 3.36 100 1,900 1,400 100 1,900 1,400 2.00 2.63 3.36 $ 161,576 $ 165,626 2.56 $ 181,314 $ 183,946 2.55 $ 201,920 $ 206,953 2.64 See Note 5.

Company experience indicates that loans and leases remain outstanding for significantly shorter periods than their contractual terms. Consumer Real Estate TCF's consumer real estate portfolio represented 25.2% and 28.5% of TCF's total loan and lease portfolio at December 31, 2017 and 2016, respectively. The consumer real estate portfolio is secured by mortgages on residential real estate and consisted of $2.0 billion of first mortgage lien loans and $2.9 billion of junior lien loans, with a decrease of $333.2 million, or 14.5%, in the first mortgage lien portfolio and an increase of $68.6 million, or 2.5%, in the junior lien portfolio, from $2.3 billion and $2.8 billion at December 31, 2016, respectively. The decrease in the consumer real estate first mortgage lien portfolio was primarily due to run-off and the non-accrual loan sales of $71.2 million during the first and third quarters of 2017. The increase in the junior lien portfolio was primarily due to the purchase of a loan portfolio of $175.4 million on September 27, 2017. The average loan size was $99 thousand for first mortgage lien loans and $48 thousand for junior lien loans at December 31, 2017, compared with $100 thousand and $47 thousand at December 31, 2016, respectively. Loans are originated for investment and for sale. Total consumer real estate originations were $2.3 billion in 2017, a decrease of $299.0 million, or 11.6%, from $2.6 billion in 2016. TCF sold $1.3 billion and $1.6 billion of consumer real estate loans in 2017 and 2016, respectively. At December 31, 2017 and 2016, 61.5% and 68.1%, respectively, of the consumer real estate portfolio were in TCF's primary banking markets. At December 31, 2017 and 2016, 62.2% and 58.0%, respectively, of the consumer real estate portfolio carried a variable or adjustable rate generally tied to the prime rate. At December 31, 2017 and 2016, 42.2% and 47.3%, respectively, of TCF's consumer real estate loans consisted of closed-end loans. TCF's closed-end consumer real estate loans require payments of principal and interest over a fixed term. The average Fair Isaac Corporation ("FICO®") credit score at loan origination for the consumer real estate portfolio was 738 and 735 at December 31, 2017 and 2016, respectively. As part of TCF's credit risk monitoring, TCF obtains updated FICO score information quarterly. The average updated FICO score for the consumer real estate portfolio was 736 and 733 at December 31, 2017 and 2016, respectively. TCF's consumer real estate underwriting standards are intended to produce adequately secured loans to customers with good credit scores at the origination date. Beginning in 2008, TCF generally has not made new loans in excess of 90% loan-to-value at origination. TCF also has not originated consumer real estate loans with multiple payment options or loans with "teaser" interest rates. At December 31, 2017, 68.3% of the consumer real estate portfolio had been originated since January 1, 2009 with net recoveries of 0.01% in 2017. TCF's consumer real estate portfolio is subject to the risk of falling home values and to the general economic environment, particularly unemployment. The consumer real estate junior lien portfolio was comprised of $2.7 billion of home equity lines of credit ("HELOCs") and $206.2 million of amortizing consumer real estate junior lien mortgage loans at December 31, 2017, compared with $2.5 billion and $272.9 million at December 31, 2016, respectively. At December 31, 2017 and 2016, $2.3 billion and $2.0 billion, respectively, of the consumer real estate junior lien HELOCs had a 10-year interest-only draw period and a 20-year amortization repayment period and all were within the 10-year interest-only draw period and will not convert to amortizing loans until 2021 or later. At December 31, 2017 and 2016, $400.4 million and $525.4 million, respectively, of the consumer real estate junior lien HELOCs were interest-only revolving draw loans with no defined amortization period and original draw periods of five to 40 years. As of December 31, 2017, 16.2% of these loans mature prior to 2021. Outstanding balances on consumer real estate lines of credit were 66.9% of total lines of credit at December 31, 2017, compared with 67.1% at December 31, 2016. 39 Commercial TCF's commercial portfolio represented 18.6% and 18.4% of TCF's total loan and lease portfolio at December 31, 2017 and 2016, respectively. The commercial portfolio consisted of $2.8 billion of commercial real estate loans and $809.9 million of commercial business loans at December 31, 2017, with increases of $117.1 million, or from $2.6 billion and $652.3 million, respectively, at 4.4%, and $157.6 million, or 24.2%, respectively, December 31, 2016. The increase in the commercial portfolio was primarily due to originations outpacing lower prepayments and pay-offs. Total commercial originations were $2.1 billion in 2017, an increase of $183.2 million, or 9.7%, from $1.9 billion in 2016. At December 31, 2017 and 2016, 74.7% and 77.8%, respectively, of TCF's commercial real estate loans outstanding were secured by properties located in TCF's primary banking markets. While commercial real estate collateral is generally located in TCF's primary banking markets, commercial real estate lending follows its strong, proven sponsors into other markets. With an emphasis on secured lending, essentially all of TCF's commercial loans were secured either by properties or other business assets at December 31, 2017 and 2016. At December 31, 2017 and 2016, variable- and adjustable-rate loans represented 73.5% and 69.0%, respectively, of total commercial loans outstanding. TCF's commercial real estate loan portfolio by property and loan type was as follows: (In thousands) Multi-family housing Office buildings Warehouse/industrial buildings Health care facilities Self-storage Retail services(1) Hotels and motels Other Total At December 31, 2017 Construction and Development Permanent Total Permanent 2016 Construction and Development Total $ 791,201 $ 178,517 $ 969,718 $ 718,562 $ 152,693 $ 871,255 305,853 309,804 262,889 246,369 251,903 199,336 18,397 56,177 4,795 34,632 44,676 5,052 41,176 508 362,030 314,599 297,521 291,045 256,955 240,512 18,905 321,970 362,092 326,536 184,543 292,036 117,312 33,236 22,058 3,156 37,372 29,771 3,662 25,739 3,453 344,028 365,248 363,908 214,314 295,698 143,051 36,689 $ 2,385,752 $ 365,533 $ 2,751,285 $ 2,356,287 $ 277,904 $ 2,634,191 (1) Primarily retail strip shopping centers and malls, convenience stores, supermarkets, restaurants and automobile related businesses. Leasing and Equipment Finance TCF's leasing and equipment finance portfolio represented 24.9% and 24.3% of TCF's total loan and lease portfolio at December 31, 2017 and 2016, respectively. The leasing and equipment finance portfolio consisted of $2.5 billion of leases and $2.3 billion of loans at December 31, 2017, with increases of $141.6 million, or 6.1%, and $283.8 million, or 14.1%, respectively, from $2.3 billion of leases and $2.0 billion of loans at December 31, 2016. The increase in the leasing and equipment finance portfolio was primarily due to a loan and lease portfolio purchase of $445.5 million on September 29, 2017. Leasing and equipment finance originations (excluding loan and lease purchases) were $2.0 billion in 2017, a decrease of $177.8 million, or 8.3%, from $2.1 billion in 2016. Leasing and equipment finance originations include operating lease originations. The uninstalled backlog of approved transactions was $506.4 million and $453.6 million at December 31, 2017 and 2016, respectively. The average loan and lease size was $77 thousand at both December 31, 2017 and 2016. See Note 2. Summary of Significant Accounting Policies of Notes to Consolidated Financial Statements for further information on lease accounting. At December 31, 2017 and 2016, $119.5 million and $140.1 million, respectively, of TCF's lease portfolio was discounted with third-party financial institutions on a non-recourse basis, which is recorded in long-term borrowings. The leasing and equipment finance portfolio table below includes lease residuals, including those related to non- recourse debt. Lease residuals represent the estimated fair value of the leased equipment at the expiration of the initial term of the transaction and are reviewed on an ongoing basis. Any downward revisions in estimated fair value are recorded to expense in the periods in which they become known. At December 31, 2017, lease residuals totaled $139.9 million, or 9.7% of original equipment value, including $6.2 million related to non-recourse sales, compared with $123.4 million, or 10.0% of original equipment value, including $7.5 million related to non-recourse sales at December 31, 2016. 40 TCF's leasing and equipment finance portfolio by equipment type was as follows: (Dollars in thousands) Specialty vehicles Construction equipment Manufacturing equipment Golf cart and turf equipment Trucks and trailers Medical equipment Furniture and fixtures Technology and data processing equipment Agricultural equipment Other Total At December 31, 2017 2016 Balance Percent of Total Balance Percent of Total $ 1,403,142 29.5% $ 1,252,951 548,575 472,902 431,888 367,206 335,636 334,732 290,999 148,269 428,312 11.5 9.9 9.1 7.7 7.1 7.0 6.1 3.1 9.0 483,231 300,368 429,382 271,870 336,566 384,975 321,562 149,192 406,213 28.9% 11.1 6.9 9.9 6.3 7.8 8.9 7.4 3.4 9.4 $ 4,761,661 100.0% $ 4,336,310 100.0% Inventory Finance TCF's inventory finance portfolio represented 14.3% and 13.8% of TCF's total loan and lease portfolio at December 31, 2017 and 2016, respectively. The inventory finance portfolio totaled $2.7 billion at December 31, 2017, an increase of $269.6 million, or 10.9%, from $2.5 billion at December 31, 2016. The increase was primarily due to strong originations and the expansion in the number of active dealers. Inventory finance originations were $7.4 billion in 2017, an increase of $721.2 million, or 10.8%, from $6.7 billion in 2016. Origination levels are impacted by the velocity of fundings and repayments with dealers. TCF's inventory finance customers included more than 10,900 and 10,800 active dealers at December 31, 2017 and 2016, respectively. TCF's inventory finance portfolio by marketing segment was as follows: (Dollars in thousands) Powersports Lawn and garden Other Total At December 31, 2017 2016 Balance Percent of Total Balance Percent of Total $ 1,187,049 43.3% $ 1,143,226 606,173 946,532 22.1 34.6 567,452 759,497 46.3% 23.0 30.7 $ 2,739,754 100.0% $ 2,470,175 100.0% Auto Finance TCF's auto finance portfolio represented 16.7% and 14.8% of TCF's total loan and lease portfolio at December 31, 2017 and 2016, respectively. The auto finance portfolio totaled $3.2 billion at December 31, 2017, an increase of $551.9 million, or 20.8%, from $2.6 billion at December 31, 2016. The increase was primarily due to the strategic shift from an originate-to-sell and originate-to-hold model to an entirely originate-to-hold model effective April 1, 2017 resulting in the reclassification of approximately $345 million of loans from held for sale to held for investment during the second quarter of 2017. Prior to April 1, 2017, loans were originated for investment and for sale. Total auto finance originations were $2.2 billion in 2017, a decrease of $1.4 billion, or 38.3%, from $3.6 billion in 2016 primarily due to the strategic shift in auto finance and the discontinuation of auto finance loan originations effective December 1, 2017. TCF sold $424.7 million and $2.1 billion of auto finance loans in 2017 and 2016, respectively. The auto finance portfolio consisted of 19.9% new auto loans and 80.1% used auto loans at December 31, 2017, compared with 23.3% and 76.7%, respectively, at December 31, 2016. The average original FICO score for the auto finance held for investment portfolio was 715 and 733 at December 31, 2017 and 2016, respectively. The decrease in the average original FICO score was primarily due to the implementation of the strategic shift. 41 Credit Quality  The following summarizes TCF's loan and lease portfolio based on the credit quality factors that TCF believes are the most important and should be considered to understand the overall condition of the portfolio. The following items should be considered throughout this section: • • • Loans and leases that are over 60-days delinquent have a higher potential to become non-accrual and generally are a leading indicator for future charge-off trends. Troubled debt restructuring ("TDR") loans are loans to financially troubled borrowers that have been modified such that TCF has granted a concession in terms to improve the likelihood of collection of all principal and modified interest owed. Non-accrual loans and leases have been charged down to the estimated fair value of the collateral less estimated selling costs, or reserved for expected loss upon workout. • Within the performing loans and leases, TCF classifies customers within regulatory classification guidelines. Loans and leases that are "classified" are loans or leases that management has concerns regarding the ability of the borrowers to meet existing loan or lease terms and conditions, but may never become non-accrual or result in a loss. Included in Note 2. Summary of Significant Accounting Policies and in Note 7. Allowance for Loan and Lease Losses and Credit Quality Information of Notes to Consolidated Financial Statements are disclosures of loans considered to be "impaired" for accounting purposes. Impairment is generally based on the present value of the expected future cash flows discounted at the loan's initial effective interest rate or for collateral dependent loans at the fair value of collateral less estimated selling costs; however, if payment or satisfaction of the loan is dependent on the operation, rather than the sale of the collateral, the impairment does not include estimated selling costs. Impaired loans include non-accrual commercial, equipment finance and inventory finance loans, as well as all TDR loans. Impaired loan accounting policies prescribe specific methodologies for determining a portion of the allowance for loan and lease losses. Past Due Loans and Leases  Over 60-day delinquent loans and leases by type, excluding non-accrual loans and leases, were as follows. Delinquent balances are determined based on the contractual terms of the loan or lease. See Note 7. Allowance for Loan and Lease Losses and Credit Quality Information of Notes to Consolidated Financial Statements for further information.

Accruing TDR loans were $114.1 million at December 31, 2017, a decrease of $12.0 million, or 9.5%, from $126.0 million at December 31, 2016. The decrease in accruing TDR loans was primarily due to a $10.5 million decrease in consumer real estate accruing TDR loans driven by payoffs and the transfer of loans to non- accrual status and an $8.1 million decrease in commercial accruing TDR loans driven by the transfer of loans to non- accrual status and payoffs. These decreases were partially offset by a $5.5 million increase in leasing and equipment finance accruing TDR loans. Non-accrual TDR loans were $41.6 million at December 31, 2017, a decrease of $39.7 million, or 48.9%, from $81.3 million at December 31, 2016. The decrease was primarily due to a $37.7 million decrease in consumer real estate non-accrual TDR loans driven by the non-accrual loan sales in the first and third quarters of 2017. TCF modifies loans through reductions in interest rates, extension of payment dates, term extensions or term extensions with a reduction of contractual payments, but generally not through reductions of principal. Loan modifications to borrowers who have not been granted concessions are not included in the table above. Loan modifications to troubled borrowers are not reported as TDR loans in the calendar years after modification if the loans were modified to an interest rate equal to or greater than the yields of new loan originations with comparable risk at the time of restructuring and if the loan is performing based on the restructured terms; however, these loans are still considered impaired and follow TCF's impaired loan reserve policies. 43     TCF typically reduces a consumer real estate customer's contractual payments by reducing the interest rate by an amount appropriate for the borrower's financial condition. Loans discharged in Chapter 7 bankruptcy where the borrower did not reaffirm the debt are reported as non-accrual TDR loans upon discharge as a result of the removal of the borrower's personal liability on the loan. These loans may return to accrual status when TCF expects full repayment of the remaining pre-discharged contractual principal and interest. At December 31, 2017, 72.0% of total consumer real estate TDR loans were accruing and TCF recognized more than 62% of the original contractual interest due on accruing consumer real estate TDR loans in 2017, yielding 4.2%, by modifying the loans to qualified customers instead of foreclosing on the property. At December 31, 2017, collection of principal and interest under the modified terms was reasonably assured on all accruing consumer real estate TDR loans. TDR loans for the remaining classes of financing receivables were not material at December 31, 2017. See Note 7. Allowance for Loan and Lease Losses and Credit Quality Information of Notes to Consolidated Financial Statements for further information regarding TCF's loan modifications.

The decrease was primarily due to the consumer real estate non-accrual loan sales of $71.2 million in the first and third quarters of 2017, partially offset by an increase in leasing and equipment finance non-accrual loans and leases. Other real estate owned was $18.2 million at December 31, 2017, a decrease of $28.6 million, or 61.1%, from $46.8 million at December 31, 2016. The decrease was primarily due to the sales of consumer real estate properties outpacing additions and sales of commercial real estate properties. See Note 2. Summary of Significant Accounting Policies and Note 7. Allowance for Loan and Lease Losses and Credit Quality Information of Notes to Consolidated Financial Statements for further information. 44 Loans and leases are generally placed on non-accrual status when the collection of interest or principal is 90 days or more past due unless, in the case of commercial loans, they are well secured and in process of collection. Delinquent consumer real estate junior lien loans are also placed on non-accrual status when there is evidence that the related third-party first lien mortgage may be 90 days or more past due, or foreclosure, charge-off or collection action has been initiated. TDR loans are placed on non-accrual status prior to the past due thresholds outlined above if repayment under the modified terms is not likely after performing a well-documented credit analysis. Loans on non-accrual status are generally reported as non-accrual loans until there is sustained repayment performance for six consecutive months, with the exception of loans not reaffirmed upon discharge under Chapter 7 bankruptcy, which remain on non-accrual status until a well-documented credit analysis indicates full repayment of the remaining pre-discharged contractual principal and interest is likely. For purposes of this disclosure, purchased credit impaired loans have been excluded. Most of TCF's non-accrual loans and past due loans are secured by real estate. Given the nature of these assets and the related mortgage foreclosure, property sale and, if applicable, mortgage insurance claims processes, it can take 18 months or longer for a loan to migrate from initial delinquency to final disposition. This resolution process generally takes much longer for loans secured by real estate than for unsecured loans or loans secured by other property primarily due to state real estate foreclosure laws.

Loan and lease credit classifications are an additional characteristic monitored in the overall credit risk process. Loan and lease credit classifications are derived from standard regulatory rating definitions, which include: non-classified (pass and special mention) and classified (substandard and doubtful). Classified loans and leases have well-defined weaknesses, but may never result in a loss. 45 Loans and leases by portfolio and regulatory classification were as follows: (In thousands) Consumer real estate Commercial Leasing and equipment finance Inventory finance Auto finance Other Non-classified Classified At December 31, 2017 Pass Special Mention Substandard Doubtful Total $ 4,706,493 $ 22,075 $ 91,128 $ — $ 4,819,696 3,452,837 4,681,488 2,553,028 3,180,807 22,507 42,729 40,252 116,312 551 — 65,627 39,921 70,414 18,281 10 — — — — — 3,561,193 4,761,661 2,739,754 3,199,639 22,517 Total loans and leases $ 18,597,160 $ 221,919 $ 285,381 $ — $ 19,104,460 (In thousands) Consumer real estate Commercial Leasing and equipment finance Inventory finance Auto finance Other Non-classified Classified At December 31, 2016 Pass Special Mention Substandard Doubtful Total $ 4,877,740 $ 40,253 $ 166,359 $ — $ 5,084,352 3,190,241 4,285,065 2,163,764 2,631,406 18,750 61,771 23,441 139,385 244 — 34,466 27,804 167,026 16,091 21 — — — — — 3,286,478 4,336,310 2,470,175 2,647,741 18,771 Total loans and leases $ 17,166,966 $ 265,094 $ 411,767 $ — $ 17,843,827 Total classified loans and leases were $285.4 million and $411.8 million at December 31, 2017 and 2016, respectively. The decrease of $126.4 million, or 30.7%, from December 31, 2016 was primarily due to decreases in classified inventory finance and consumer real estate loans, partially offset by increases in classified commercial loans and classified leasing and equipment finance loans and leases. The decrease in classified inventory finance loans was due to enhancements made to the model used to determine the classifications of loans in the first quarter of 2017 that better align with the inherent risk in this portfolio. The decrease in classified consumer real estate loans was a result of the non-accrual loan sales in the first and third quarters of 2017. Allowance for Loan and Lease Losses  The determination of the allowance for loan and lease losses is a critical accounting estimate. TCF's evaluation of incurred losses is based on historical loss rates multiplied by the respective portfolio's loss emergence period. Factors utilized in the determination of the amount of the allowance include historical trends in loss rates, a portfolio's overall risk characteristics, changes in its character or size, risk rating migration, delinquencies, collateral values, economic outlook and prevailing economic conditions. The various factors used in the methodologies are reviewed on a periodic basis. The Company considers the allowance for loan and lease losses of $171.0 million appropriate to cover losses incurred in the loan and lease portfolios at December 31, 2017. However, no assurance can be given that TCF will not, in any particular period, sustain loan and lease losses that are sizable in relation to the amount reserved or will not require significant changes in the balance of the allowance for loan and lease losses due to subsequent evaluations of the loan and lease portfolios, in light of factors then prevailing, including economic conditions, information obtained during TCF's ongoing credit review process or regulatory requirements. Among other factors, an economic slowdown, increasing levels of unemployment, a decline in collateral values and/or rising interest rates may have an adverse impact on the current adequacy of the allowance for loan and lease losses by increasing credit risk and the risk of potential loss. 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. 46   In conjunction with Note 7.

Net charge-offs for 2017 were $44.4 million, or 0.24% of average loans and leases, compared with $45.2 million, or 0.26% of average loans and leases for 2016 and $51.5 million, or 0.30% of average loans and leases for 2015. Net charge-offs decreased $0.8 million in 2017 primarily due to the recovery of $13.3 million on previous charge-offs related to the consumer real estate non-accrual loans that were sold in the first and third quarters of 2017, partially offset by increased net charge-offs in the auto finance, commercial and leasing and equipment finance portfolios. The increase in auto finance charge-offs was primarily due to the strategic shift from an originate-to-sell and originate-to-hold model to an entirely originate-to-hold model, maturation of the portfolio and lower recoveries. The increase in commercial charge-offs was primarily due to the charge-off of two loans during 2017. The increase in leasing and equipment finance charge-offs was primarily due to the charge-off of one loan in the fourth quarter of 2017. Net charge-offs decreased $6.3 million in 2016 primarily due to a decrease in consumer real estate net charge-offs, partially offset by an increase in auto finance net charge-offs. The decrease in net charge-offs in the consumer real estate portfolio was primarily due to improved credit quality and increased home values. The increase in net charge-offs in the auto finance portfolio was primarily due to the maturation of the portfolio and an industry decline in used auto values. 48 Liquidity Management TCF manages its liquidity to ensure that its funding needs are met both promptly and in a cost-effective manner. Asset liquidity arises from liquid assets that can be sold or pledged as collateral, amortization, prepayment or maturity of assets and from the ability of TCF to sell loans. Liability liquidity results from the ability of TCF to maintain a diverse set of funding sources to promptly meet funding requirements. TCF's Asset & Liability Committee ("ALCO") and the Finance Committee of TCF Financial's Board of Directors have adopted a Liquidity Management Policy for TCF Bank to direct management of the Company's liquidity risk. See "Item 7A. Quantitative and Qualitative Disclosures about Market Risk" for further information. TCF Bank had $242.6 million and $256.6 million of net liquidity qualifying interest-bearing deposits at the Federal Reserve Bank at December 31, 2017 and 2016, respectively. Interest-bearing deposits held at the Federal Reserve Bank and unencumbered U.S. Government sponsored enterprises and federal agencies mortgage-backed securities were $1.2 billion at both December 31, 2017 and 2016. In addition, TCF held unencumbered obligations of states and political subdivisions totaling $814.3 million and $612.5 million at December 31, 2017 and 2016, respectively. ALCO and the Finance Committee of TCF Financial's Board of Directors have adopted a Holding Company Investment and Liquidity Management Policy, which establishes a minimum target amount of cash or liquid investments TCF Financial will hold. See "Item 7A. Quantitative and Qualitative Disclosures about Market Risk" for further information. TCF Financial had cash and due from banks of $80.5 million and $69.7 million at December 31, 2017 and 2016, respectively. Deposits are the primary source of TCF's funds for use in lending and for other general business purposes. In addition to deposits, TCF receives funds from loan and lease repayments, loan sales and borrowings. Lending activities, such as loan originations and purchases and equipment purchases for lease financing, are the primary uses of TCF's funds. Deposit inflows and outflows are significantly influenced by general interest rates, money market conditions, competition for funds, customer service and other factors. TCF's deposit inflows and outflows have been and will continue to be affected by these factors. Borrowings may be used to compensate for reductions in normal sources of funds, such as deposit inflows at less than projected levels, net deposit outflows or to fund balance sheet growth. Historically, TCF has borrowed primarily from the Federal Home Loan Bank ("FHLB") of Des Moines, institutional sources under repurchase agreements and other sources. TCF had $1.6 billion of additional borrowing capacity at the FHLB of Des Moines at December 31, 2017, as well as access to the Federal Reserve Discount Window. In addition, TCF maintains a diversified set of unsecured and uncommitted funding sources, including access to overnight federal funds purchased lines, brokered deposits and capital markets. The primary source of funding for TCF Commercial Finance Canada, Inc. ("TCFCFC") is a line of credit with TCF Bank. TCFCFC also maintains a $20.0 million Canadian dollar-denominated line of credit facility with a counterparty, which is guaranteed by TCF Bank. TCFCFC had no outstanding borrowings at December 31, 2017 and $2.2 million (USD) outstanding under the line of credit with the counterparty at December 31, 2016. Deposits  Deposits totaled $18.3 billion at December 31, 2017, an increase of $1.1 billion, or 6.3%, from $17.2 billion at December 31, 2016. The increase was primarily due to growth in certificates of deposit, savings and checking balances, partially offset by a decrease in money market balances. Non-interest bearing checking accounts represented 20.0% of total deposits at both December 31, 2017 and 2016. TCF's weighted-average interest rate for deposits, including non-interest bearing deposits, was 0.38% and 0.36% at December 31, 2017 and 2016, respectively. The increase was primarily due to increased average interest rates resulting from promotions for certificates of deposit and savings accounts, partially offset by decreased average interest rates on money market balances. Checking, savings and certain money market deposits are an important source of low cost or no cost funds for TCF. The average balance of these types of deposits was $10.8 billion and $10.6 billion for 2017 and 2016, respectively. These deposits comprised approximately 61% and 62% of total average deposits for 2017 and 2016, respectively. 49 Certificates of deposit totaled $5.0 billion and $4.1 billion at December 31, 2017 and 2016, respectively. The maturities of certificates of deposit with denominations equal to or greater than $100,000 were as follows: (In thousands) Maturity: Three months or less Over three through six months Over six through 12 months Over 12 months  Total Denominations $100 Thousand or Greater at December 31, 2017 $ $ 216,861 320,214 957,052 949,329 2,443,456 Borrowings  Borrowings totaled $1.2 billion and $1.1 billion at December 31, 2017 and 2016, respectively. Historically, TCF has borrowed primarily from the FHLB of Des Moines, institutional sources under repurchase agreements and other sources. See Note 12. Short-term Borrowings and Note 13. Long-term Borrowings of Notes to Consolidated Financial Statements for further information regarding TCF's borrowings. Contractual Obligations and Commitments As discussed further in Note 8.

TCF's campus marketing agreement consists of fixed and minimum obligations for exclusive marketing rights and naming rights with one university. TCF is obligated to make annual payments for the exclusive marketing rights through 2023, with a renewal option to extend the terms through 2029. TCF is obligated to make annual payments for the exclusive naming rights through 2030 and TCF has the option to extend the terms through 2040 upon making a renewal option payment. Liabilities related to acquisition and portfolio purchase consist of a liability of $5.9 million to be paid within three years related to TCF's acquisition of EFLC, as well as liabilities related to the leasing and equipment finance loan and lease portfolio purchase. See Note 9. Goodwill and Other Intangible Assets for further information. Commitments to extend credit are agreements to lend to a customer provided there is no violation of any condition in the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since certain of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Collateral to secure any funding of these commitments predominantly consists of residential and commercial real estate. Standby letters of credit and guarantees on industrial revenue bonds are conditional commitments issued by TCF guaranteeing the performance of a customer to a third party. These conditional commitments expire in various years through 2021. Collateral held consists primarily of commercial real estate mortgages. Since the conditions under which TCF is required to fund these commitments may not materialize, the cash requirements are expected to be less than the total outstanding commitments. Capital Management  TCF is committed to managing capital to maintain protection for stockholders, depositors and creditors. TCF employs a variety of capital management tools to achieve its capital goals, including, but not limited to, dividends, public offerings of preferred and common stock, common stock repurchases, redemption of preferred stock and the issuance or redemption of subordinated debt and other capital instruments. TCF maintains a Capital Planning and Dividend Policy which applies to TCF Financial and incorporates TCF Bank's Capital Planning and Dividend Policy. These policies ensure that capital strategy actions, including the addition of new capital, if needed, common stock repurchases, redemption of preferred stock or the declaration of preferred stock, common stock and bank dividends are prudent, efficient and provide value to TCF's stockholders, while ensuring that past and prospective earnings retention is consistent with TCF's capital needs, asset quality and overall financial condition. TCF and TCF Bank manage their capital levels to exceed all regulatory capital requirements, which were achieved at December 31, 2017 and 2016. See Note 16. Regulatory Capital Requirements of Notes to Consolidated Financial Statements for further information. Equity  Total equity at December 31, 2017 was $2.7 billion, or 11.7% of total assets, compared with $2.4 billion, or 11.4% of total assets, at December 31, 2016. Preferred Stock Preferred stock was $265.8 million at December 31, 2017, an increase of $2.6 million, or 1.0%, from $263.2 million at December 31, 2016. The increase was primarily due to the issuance of the Series C non-cumulative perpetual preferred stock, partially offset by the redemption of the Series A non-cumulative perpetual preferred stock. At December 31, 2017 and 2016, there were 4,000,000 shares outstanding of the 6.45% Series B non-cumulative perpetual preferred stock of TCF Financial Corporation, par value $0.01 per share, with a liquidation preference of $25 per share (the "Series B Preferred Stock"). Dividends are payable on the Series B Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year at a per annum rate of 6.45%. The Series B Preferred Stock may be redeemed at TCF's option in whole or in part at any time. On January 30, 2018, TCF's Board of Directors approved the redemption of all outstanding shares of the Series B Preferred Stock on March 1, 2018. 51   At December 31, 2017, there were 7,000,000 depositary shares outstanding, each representing a 1/1000th ownership interest in a share of the 5.70% Series C non-cumulative perpetual preferred stock of TCF Financial Corporation, par value $0.01 per share, with a liquidation preference of $25,000 per share (equivalent to $25 per depositary share) (the "Series C Preferred Stock"). Dividends are payable on the Series C Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year at a per annum rate of 5.70%. The Series C Preferred Stock may be redeemed at TCF's option in whole or in part on December 1, 2022 or on any dividend payment date thereafter. The Series C Preferred Stock was issued on September 14, 2017 for an aggregate public offering price of $175.0 million. Net proceeds of the offering to TCF, after deducting deferred stock issuance costs of $5.7 million, were $169.3 million. On October 16, 2017, TCF redeemed the 6,900,000 depositary shares, each representing a 1/1000th ownership interest in a share of the 7.50% Series A non-cumulative perpetual preferred stock of TCF Financial Corporation, par value $0.01 per share, with a liquidation preference of $25,000 per share (equivalent to $25 per depositary share) (the "Series A Preferred Stock") for $172.5 million using the net proceeds from the offering of its Series C depositary shares and additional cash on hand. Dividends were payable on the Series A Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year at a per annum rate of 7.50%. Common Stock TCF repurchased 446,464 shares of its common stock during the fourth quarter of 2017 at an average cost of $20.51 per share under its share repurchase program. At December 31, 2017, TCF had the ability to purchase up to $140.8 million in aggregate value of shares of TCF's common stock in its stock repurchase program authorized by its Board of Directors on November 27, 2017. Future repurchases will be based on market conditions, the trading price of TCF shares and other factors. The ability to repurchase shares in the future may be adversely affected by new legislation or regulations or by changes in regulatory policies. This authorization may be commenced or suspended at any time or from time to time. Dividends to common stockholders on a per share basis totaled 7.5 cents for each quarter of the years ended December 31, 2017 and 2016, respectively. TCF's common dividend payout ratio for the quarters ended December 31, 2017 and 2016 was 13.2% and 27.8%, respectively. On January 30, 2018, TCF's Board of Directors declared a regular quarterly cash dividend of 15.0 cents per common share, an increase of 100.0 percent, payable on March 1, 2018 to stockholders of record at the close of business on February 15, 2018. TCF Financial's primary funding sources for dividends are earnings and dividends received from TCF Bank. Total common stockholders' equity at December 31, 2017 was $2.4 billion, or 10.42% of total assets, compared with $2.2 billion, or 10.09% of total assets, at December 31, 2016. Tangible common equity at December 31, 2017 was $2.2 billion, or 9.72% of total tangible assets, compared with $1.9 billion, or 9.13% of total tangible assets, at December 31, 2016. Tangible common equity and tangible assets are not financial measures recognized under generally accepted accounting principles in the United States ("GAAP") (i.e., non-GAAP). Tangible common equity represents total equity less non-controlling interest in subsidiaries, preferred stock, goodwill and other intangible assets. 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 provide investors, regulators and other users with information to be viewed in relation to other banking institutions. 52 Reconciliations of the non-GAAP financial measures of tangible common equity and tangible assets to the GAAP measures of total equity and total assets were as follows: (Dollars in thousands) 2017 2016 2015 2014 2013 At December 31, Computation of tangible common equity to tangible assets: Total equity $ 2,680,584 $ 2,444,645 $ 2,306,917 $ 2,135,364 $ 1,964,759 Less: Non-controlling interest in subsidiaries 17,827 17,162 16,001 13,715 11,791 Total TCF Financial Corporation stockholders' equity Less: Preferred stock 2,662,757 2,427,483 2,290,916 2,121,649 1,952,968 265,821 263,240 2,164,243 263,240 263,240 263,240 2,027,676 1,858,409 1,689,728 Total common stockholders' equity (a) 2,396,936 Less: Goodwill, net Other intangibles, net(1) Tangible common equity Total assets Less: Goodwill, net Other intangibles, net(1) Tangible assets Common equity to assets Tangible common equity to tangible assets (1) Includes non-mortgage servicing assets.

Summary of Significant Accounting Policies of Notes to Consolidated Financial Statements for further discussion of critical accounting estimates. 53 Recent Accounting Developments In August 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-12: Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which expands hedge accounting for nonfinancial and financial risk components and amends measurement methodologies to more closely align hedge accounting with a company's risk management activities. The ASU decreases the complexity of preparing and understanding hedge results through measurement and reporting of hedge ineffectiveness. In addition, disclosures will be enhanced and the presentation of hedged results changed to align the effects of the hedging instrument and the hedged item. The adoption of this ASU will be required on a modified retrospective basis beginning with TCF's Quarterly Report on Form 10-Q for the quarter ending March 31, 2019; however early adoption is allowed. TCF adopted this ASU effective January 1, 2018. The adoption of this guidance will not have a material impact on our consolidated financial statements. In May 2017, the FASB issued ASU No. 2017-09: Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting, which provides guidance about which changes to the terms and conditions of a share-based payment award requires an entity to apply modification accounting in Topic 718. The adoption of this ASU will be required on a prospective basis to an award modified beginning with TCF's Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Early adoption is allowed. The adoption of this guidance will not have a material impact on our consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07: Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which will change how employers that sponsor defined benefit pension and/or other postretirement benefit plans present the net periodic benefit cost in the income statement. Under the new guidance, employers will present the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. Only the service cost component will be eligible for capitalization in assets. The other components of net periodic benefit cost will be presented separately from the line item that includes service cost and outside of any subtotal of operating income. In addition, disclosure of the line items used to present the other components of net periodic benefit cost is required if the components are not presented separately in the income statement. The adoption of this ASU will be required on either a full or modified retrospective basis beginning with TCF's Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Early adoption is allowed. The adoption of this guidance will not have a material impact on our consolidated financial statements. In February 2017, the FASB issued ASU No. 2017-05: Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20), which provides guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with non-customers. The ASU also clarifies that Accounting Standards Codification ("ASC") 610-20 applies to the derecognition of nonfinancial assets and in substance nonfinancial assets unless other specific guidance applies or the sale is to a customer. The new guidance does not apply to the derecognition of businesses, nonprofit activities, financial assets, including equity method investments, or to revenue contracts with customers. The adoption of this ASU will be required on either a full or modified retrospective basis beginning with TCF's Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Early adoption is allowed. The adoption of this guidance will not have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies the definition of a business with the objective of adding guidance to assist companies with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The ASU provides a more robust framework to use in determining when a set of assets and activities is a business. The adoption of this ASU will be required on a prospective basis beginning with TCF's Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Upon adoption, TCF will evaluate future transactions to determine if they should be accounted for as acquisitions (or disposals) of assets or businesses. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires entities to show changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. The adoption of this ASU will be required on a retrospective basis beginning with TCF's Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. The adoption of this guidance will not have a material impact on our consolidated financial statements. 54 In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain types of cash receipts and cash payments are presented in the statement of cash flows. The adoption of this ASU will be required on a retrospective basis beginning with TCF's Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Early adoption is allowed. The adoption of this guidance will not have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial assets, including trade and other receivables, held to maturity debt securities, loans and purchased financial assets with credit deterioration. The ASU requires the use of a current expected credit loss ("CECL") approach to determine the allowance for credit losses for loans and held to maturity securities. CECL requires loss estimates for the remaining estimated life of the asset using historical loss data as well as reasonable and supportable forecasts based on current economic conditions. The adoption of this ASU will be required on a modified retrospective basis with a cumulative-effect adjustment required beginning with TCF's Quarterly Report on Form 10-Q for the quarter ending March 31, 2020. Early adoption is allowed. Management is currently evaluating the potential impact of this guidance on our consolidated financial statements. CECL represents a significant change in GAAP and may result in a material impact on our consolidated financial statements. The impact of the ASU will depend on the composition of TCF's portfolios and general economic conditions at the date of adoption. Additionally, there are several implementation questions which could affect the adoption impact once resolved. TCF has established a governance structure to implement the ASU and is in the process of assessing its current processes and determining future methodologies to be used upon adoption. In March 2016, the FASB issued ASU No. 2016-04, Liabilities - Extinguishment of Liabilities (Subtopic 405-20): Recognition of Breakage for Certain Prepaid Stored-Value Products, which requires issuers of prepaid stored-value products redeemable for goods, services or cash at third-party merchants to derecognize liabilities related to those products for breakage. The adoption of this ASU will be required on a retrospective or modified retrospective basis beginning with TCF's Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Early adoption is allowed. The adoption of this guidance will not have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which, along with other amendments, requires lessees to recognize most leases on their balance sheet. Lessor accounting is largely unchanged. The ASU requires both quantitative and qualitative disclosure regarding key information about leasing arrangements from both lessees and lessors. In September 2017, the FASB issued ASU No. 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840) and Leases (Topic 842): Amendments to SEC Paragraphs, which rescinds certain SEC Observer comments and staff announcements from the lease guidance and incorporates SEC staff announcements on the effect of a change in tax law on leverage leases from ASC 840 into ASC 842. The adoption of these ASUs will be required on a modified retrospective basis beginning with TCF's Quarterly Report on Form 10-Q for the quarter ending March 31, 2019. Early adoption is allowed. Management has started to implement this ASU which has included an initial evaluation of TCF's leasing contracts and activities. Management has evaluated and plans to elect the practical expedients, which would allow for existing leases to be accounted for consistent with current guidance, with the exception of the balance sheet recognition for lessees. The adoption of this guidance is not expected to result in a material change to lessee expense recognition. While there are limited changes to lessor accounting, there are certain implementation questions whose resolution may result in changes in recognition and measurement from current practice. Management will continue to evaluate the impact of this guidance on our consolidated financial statements. 55 In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which requires revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delays the effective date of the new revenue recognition requirements in ASU No. 2014-09 by one year. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies how an entity should identify the unit of accounting for the principal versus agent evaluation and how it should apply the control principle to certain types of arrangements by explaining what a principal controls before the specified good or service is transferred to the customer. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which amends the guidance for identifying performance obligations and accounting for a license which grants the right to use intellectual property. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides narrow-scope improvements to transition, collectability, noncash consideration and the presentation of sales and other similar taxes. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which provides guidance that affects narrow aspects of the guidance issued in ASU No. 2014-09. In September 2017, the FASB issued ASU 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840) and Leases (Topic 842): Amendments to SEC Paragraphs, which rescinds certain SEC Observer comments on accounting for management fees based on a formula that is codified in ASC 605. In November 2017, the FASB issued ASU 2017-14, Income Statement - Reporting Comprehensive Income (Topic 220), Revenue Recognition (Topic 605) and Revenue from Contracts with Customers (Topic 606), which amends certain paragraphs in ASC 605 by superseding the paragraphs with a link to ASC 606.The adoption of these ASUs will be required using one of two retrospective application methods beginning with TCF's Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. TCF plans to apply the modified retrospective method with a cumulative-effect adjustment to opening retained earnings. TCF derives a majority of its revenue from loans and leases, as well as any related servicing fee revenue, which are not within the scope of these ASUs. These ASUs are applicable to most of the fees and service charges, card and ATM revenue earned by TCF, as well as the gains on sales of certain non-financial assets. However, the recognition of these revenue streams does not change in a significant manner as a result of the adoption of these ASUs. The majority of this revenue is both charged to the customer and earned either at a point in time or on a transactional basis. As a result, the revenue expected to be recognized in any future year related to remaining performance obligations, contracts where revenue is recognized when invoiced and contracts with variable consideration related to undelivered performance obligations are not material. In addition, receivables related to fees and service charges and the related bad debt expense are not material. There are no material contract assets, contract liabilities or deferred contract costs recorded in the Company's Consolidated Statements of Financial Condition. As a significant majority of the Company's revenue streams are not included in the scope of these ASUs and the recognition of revenue for the revenue streams within the scope of these ASUs are not significantly changed, the adoption of this guidance will not have a material impact on the Company's consolidated financial statements. 56 Forward-looking Information Any statements contained in this Annual Report on Form 10-K regarding the outlook for the Company's businesses and their respective markets, such as projections of future performance, targets, guidance, statements of the Company's plans and objectives, forecasts of market trends and other matters, are forward-looking statements based on the Company's assumptions and beliefs.

Quantitative and Qualitative Disclosures About Market Risk TCF's results of operations depend, to a large degree, on its net interest income and its ability to manage interest rate risk. Although TCF manages other risks in the normal course of business, such as credit risk, liquidity risk and foreign currency risk, the Company considers interest rate risk to be one of its more significant market risks. Interest Rate Risk TCF's ALCO and the Finance Committee of TCF Financial's Board of Directors have adopted interest rate risk policy limits which are incorporated into the Company's investment policy. Interest rate risk is defined as the exposure of net interest income and fair value of financial instruments (interest-earning assets, deposits and borrowings) to movements in interest rates. Since TCF does not hold a trading portfolio, the Company is not exposed to market risk from trading activities. As such, the major sources of the Company's interest rate risk are timing differences in the maturity and repricing characteristics of assets and liabilities, changes in the shape of the yield curve, changes in consumer behavior and changes in relationships between rate indices (basis risk). Management measures these risks and their impact in various ways, including through the use of simulation and valuation analyses. The interest rate scenarios may include gradual or rapid changes in interest rates, spread narrowing and widening, yield curve twists and changes in assumptions about consumer behavior in various interest rate scenarios. A mismatch between maturities, interest rate sensitivities and prepayment characteristics of assets and liabilities results in interest rate risk. TCF, like most financial institutions, has material interest rate risk exposure to changes in both short- and long-term interest rates, as well as variable interest rate indices (e.g., the prime rate or the London InterBank Offered Rate). TCF's ALCO is responsible for reviewing the Company's interest rate sensitivity position and establishing policies to monitor and limit exposure to interest rate risk. ALCO manages TCF's interest rate risk based on interest rate expectations and other factors. The principal objective of TCF in managing its assets and liabilities is to provide maximum levels of net interest income and facilitate the funding needs of the Company, while maintaining acceptable levels of interest rate risk and liquidity risk. ALCO primarily uses two interest rate risk tools with policy limits to evaluate TCF's interest rate risk: net interest income simulation and economic value of equity ("EVE") analysis. In addition, the interest rate gap is reviewed periodically to monitor asset and liability repricing over various time periods. Management utilizes net interest income simulation models to estimate the near-term effects of changing interest rates on its net interest income. Net interest income simulation involves forecasting net interest income under a variety of scenarios, including the level of interest rates, the shape of the yield curve and the spreads between market interest rates. Management exercises its best judgment in making assumptions regarding events that management can influence, such as non-contractual deposit repricings and events outside management's control, including consumer behavior on loan and deposit activity and the effect that competition has on both loan and deposit pricing. These assumptions are subjective and, as a result, net interest income simulation results will differ from actual results due to the timing, magnitude and frequency of interest rate changes and changes in market conditions, consumer behavior and management strategies, among other factors. TCF performs various sensitivity analyses on assumptions of new loan spreads, prepayment rates, basis risk, deposit attrition and deposit repricing. The following table presents changes in TCF's net interest income over a twelve month period if short- and long-term interest rates were to sustain an immediate increase of 100 basis points and 200 basis points. The impact of planned changes to interest-earning assets and new business activities is factored into the simulation model. (Dollars in millions) Immediate Change in Interest Rates: +200 basis points +100 basis points $ 2017 97.5 53.1 10.1% $ 5.5 2016 97.2 52.1 10.9% 5.9 Impact on Net Interest Income December 31, 59     As of December 31, 2017, approximately 61% of TCF's loan and lease balances were expected to reprice, amortize or prepay in the next 12 months and approximately 61% of TCF's deposit balances were low cost or no cost deposits. TCF believes that the mix of assets repricing compared with low cost or no cost deposits positions TCF well for rising interest rates. Management also uses EVE and interest rate gap analyses to measure risk in the balance sheet that might not be taken into account in the net interest income simulation analysis. Net interest income simulation highlights exposure over a relatively short time period, while EVE analysis incorporates all cash flows over the estimated remaining life of all balance sheet positions. The valuation of the balance sheet, at a point in time, is defined as the discounted present value of asset cash flows minus the discounted present value of liability cash flows. EVE analysis addresses only the current balance sheet and does not incorporate the planned changes to interest-earning assets that are used in the net interest income simulation model. As with the net interest income simulation model, EVE analysis is based on key assumptions about the timing and variability of balance sheet cash flows and does not take into account any potential responses by management to anticipated changes in interest rates. Interest rate gap is primarily the difference between interest-earning assets and interest-bearing liabilities repricing within a given period and represents the net asset or liability sensitivity at a point in time. An interest rate gap measure could be significantly affected by external factors such as loan prepayments, early withdrawals of deposits, changes in the correlation of various interest-bearing instruments, competition, or a rise or decline in interest rates. Credit Risk Credit risk is defined as the risk to earnings or capital if an obligor fails to meet the terms of any contract with the Company or otherwise fails to perform as agreed, such as the failure of customers and counterparties to meet their contractual obligations, as well as contingent exposures from unfunded loan commitments and letters of credit. TCF's Enterprise Risk Management Committee meets at least quarterly and is responsible for monitoring the loan and lease portfolio composition and risk tolerance within the various segments of the portfolio. The Enterprise Risk Management Committee and the Board of Directors have adopted a Risk Appetite Statement to manage the Company's credit risk by setting (i) a desired balance between asset classes, (ii) concentration limits based on loan type, business line and geographic region and (iii) maximum tolerances for credit performance. To manage credit risk arising from lending and leasing activities, management has adopted and maintains underwriting policies and procedures and periodically reviews the appropriateness of these policies and procedures. Customers and guarantors or recourse providers are evaluated as part of initial underwriting processes and through periodic reviews. For consumer loans, credit scoring models are used to help determine eligibility for credit and terms of credit. These models are periodically reviewed to verify that they are predictive of borrower performance. Limits are established on the exposure to a single customer (including affiliates) and on concentrations for certain categories of customers. Loan and lease credit approval levels are established so that larger credit exposures receive managerial review at the appropriate level through the credit committees. Management continuously monitors asset quality in order to manage the Company's credit risk and to determine the appropriateness of valuation allowances, including, in the case of commercial loans, inventory finance loans and equipment finance loans and leases, a risk rating methodology under which a rating of one through nine is assigned to each loan or lease. The rating reflects management's assessment of the potential impact on repayment of the customer's financial and operational condition. Asset quality is monitored separately based on the type or category of loan or lease. The rating process allows management to better define the Company's loan and lease portfolio risk profile. Management also uses various risk models to estimate probable impact on payment performance under various scenarios, both expected and unexpected. The Company also has credit risk in its securities portfolio related to obligations of states and political subdivisions. The Company maintains a restrictive set of underwriting criteria and regularly monitors credit performance under the direction and supervision of the TCF Bank Credit Committee to manage this risk. Credit risk in the remainder of the securities portfolio is minimal. The remainder of the securities available for sale and securities held to maturity portfolios as of December 31, 2017 consist primarily of fixed-rate mortgage-backed securities issued and guaranteed by Fannie Mae. All investment related counterparties and transaction limits are reviewed and approved annually by both ALCO and the TCF Bank Credit Committee. 60 Liquidity Risk Liquidity risk is defined as the risk to earnings or capital arising from the Company's inability to meet its obligations when they come due without incurring unacceptable losses. ALCO and the Finance Committee of TCF Financial's Board of Directors have adopted a Holding Company Investment and Liquidity Management Policy, which establishes a minimum target amount of cash or liquid investments TCF Financial will hold. TCF Financial's primary source of cash flow is capital distributions from TCF Bank. TCF Bank may be required to receive regulatory approval prior to making any such distributions in the future and such distributions may be restricted by its federal banking regulators. 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. See "Item 1. Business - Regulation - Restrictions on Distributions", Note 16. Regulatory Capital Requirements and Note 25. Parent Company Financial Information of Notes to Consolidated Financial Statements for further information. ALCO and the Finance Committee of TCF Financial's Board of Directors have adopted a Liquidity Management Policy for TCF Bank to direct management of the Company's liquidity risk. The objective of the Liquidity Management Policy is to ensure that TCF meets its cash and collateral obligations promptly, in a cost-effective manner and with the highest degree of reliability. The maintenance of adequate levels of asset and liability liquidity will provide TCF with the ability to meet both expected and unexpected cash flows and collateral needs. Key liquidity ratios, asset liquidity levels and the amount available from funding sources are reported to ALCO on a monthly basis. TCF's Liquidity Management Policy defines liquidity stress scenarios and establishes asset liquidity target ranges based on those stress scenarios that are deemed appropriate for its risk profile. TCF's asset liquidity may be held in the form of on-balance sheet cash invested with the Federal Reserve Bank or other highly liquid marketable securities that are not pledged and can be sold or pledged to various counterparties under established agreements. Interest-bearing deposits held at the Federal Reserve Bank and unencumbered U.S. Government sponsored enterprises and federal agencies mortgage-backed securities were $1.2 billion at December 31, 2017. In addition, TCF held unencumbered obligations of states and political subdivisions totaling $814.3 million at December 31, 2017. Deposits are TCF's primary source of funding. TCF also maintains secured sources of funding, which primarily include $1.6 billion of additional borrowing capacity at the FHLB of Des Moines at December 31, 2017, as well as access to the Federal Reserve Discount Window. Collateral pledged by TCF to the FHLB and the Federal Reserve Bank may consist of consumer and commercial real estate loans and mortgage-backed securities. The FHLB relies on its own internal credit analysis of TCF when determining TCF's secured borrowing capacity. In addition to the above, TCF maintains a diversified set of unsecured and uncommitted funding sources, including access to overnight federal funds purchased lines, brokered deposits and capital markets. TCF has developed and maintains a contingency funding plan should certain liquidity needs arise. Foreign Currency Risk The Company is also exposed to foreign currency risk as changes in the exchange rate of the Canadian dollar may impact the Company's investment in TCFCFC. TCF enters into forward foreign exchange contracts in order to minimize the risk of changes in foreign exchange rates on its investment in and loans to TCFCFC. The values of forward foreign exchange contracts vary over their contractual lives as the related currency exchange rates fluctuate. TCF may also experience realized and unrealized gains or losses on forward foreign exchange contracts as a result of changes in foreign exchange rates. See Note 2.

Financial Statements and Supplementary Data Report of Independent Registered Public Accounting Firm To the Stockholders and Board of Directors TCF Financial Corporation: Opinion on the Consolidated Financial Statements We have audited the accompanying consolidated statements of financial condition of TCF Financial Corporation and subsidiaries (the "Company") as of December 31, 2017 and 2016, and the related consolidated statements of income, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2017, and the related notes (collectively, the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three- year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 23, 2018 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. We have served as the Company's auditor since 1991.

Basis of Presentation TCF Financial Corporation (together with its direct and indirect subsidiaries, "we," "us," "our," "TCF" or the "Company"), a Delaware corporation, is a national bank holding company based in Wayzata, Minnesota. References herein to "TCF Financial" or the "Holding Company" refer to TCF Financial Corporation on an unconsolidated basis. TCF's principal subsidiary, TCF National Bank ("TCF Bank"), is headquartered in Sioux Falls, South Dakota. TCF Bank operates bank branches in Illinois, Minnesota, Michigan, Colorado, Wisconsin, Arizona and South Dakota (TCF's primary banking markets), providing convenient financial services, including select locations open seven days a week with extended hours and on most holidays, full-service supermarket branches, access to automated teller machine ("ATM") networks and digital banking channels. Through its direct subsidiaries, TCF Bank also provides a full range of consumer facing and commercial services, including providing consumer banking services in 46 states, commercial banking services in 34 states, commercial leasing and equipment financing in all 50 states and, to a limited extent, in foreign countries and commercial inventory financing in all 50 states and Canada and, to a limited extent, in other foreign countries. The accompanying consolidated financial statements are prepared in conformity with U.S. generally accepted accounting principles ("GAAP"). 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. 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. Effective April 1, 2017, the Company executed its strategic shift from an originate-to-sell and originate-to-hold model to an entirely originate-to-hold model for its auto finance business and effective December 1, 2017, the Company discontinued auto finance loan originations. The determination was based on management's review of strategic alternatives and the financial outlook of the auto finance loan origination business compared with alternative uses of capital. TCF's subsidiary, Gateway One Lending & Finance, LLC ("Gateway One"), will continue to service existing auto loans on its balance sheet and those serviced for others. The decision to discontinue auto finance loan originations resulted in a goodwill impairment charge of $73.0 million, an other intangible assets impairment charge of $0.4 million and approximately $14.8 million of expenses related to severance, other asset impairments and lease termination expenses in 2017. Note 2. Summary of Significant Accounting Policies Critical Accounting Estimates Critical accounting estimates occur in certain accounting policies and procedures and are particularly susceptible to significant change. Policies that contain critical accounting estimates include the determination of the allowance for loan and lease losses and the determination of current and deferred income taxes. Allowance for Loan and Lease Losses The allowance for loan and lease losses is maintained at a level believed to be appropriate to provide for probable loan and lease losses incurred in the portfolio as of the balance sheet date, including known or anticipated problem loans and leases, as well as for loans and leases which are not currently known to require specific allowances. Loans classified as troubled debt restructuring ("TDR") loans are considered impaired loans, along with non-accrual commercial, equipment finance and inventory finance loans. TCF individually evaluates impairment on all impaired loans and all non-accrual leases and other consumer real estate, commercial and auto finance loans specifically identified for evaluation. All other loans and leases are evaluated collectively for impairment. Loan impairment on consumer real estate TDR loans is a key component of the allowance for loan and lease losses. Impairment is generally based on the present value of the expected future cash flows discounted at the loan's initial effective interest rate, unless the loans are collateral dependent, in which case loan impairment is based on the fair value of the collateral less estimated selling costs. 68   Impairment on commercial loans, inventory finance loans and leasing and equipment finance loans and leases is generally based on the present value of the expected future cash flows discounted at the initial effective interest rate of the loan or lease, unless the loan or lease is collateral dependent, in which case impairment is based on the fair value of collateral less estimated selling costs; however, if payment or satisfaction of the loan or lease is dependent on the operation, rather than the sale of the collateral, the impairment does not include estimated selling costs. Impairment on auto finance loans is generally based on the fair value of collateral less estimated selling costs. The impairment for all other loans and leases is evaluated collectively by various characteristics. The collective evaluation of incurred losses in these portfolios is based on their historical loss rates multiplied by the respective loss emergence period. Factors utilized in the determination of the amount of the allowance include historical trends in loss rates, a portfolio's overall risk characteristics, changes in its character or size, risk rating migration, delinquencies, collateral values, economic outlook and prevailing economic conditions. The various factors used in the methodologies are reviewed on a periodic basis. Loans and leases are charged off to the extent they are deemed to be uncollectible. Charge-offs related to losses are utilized in the historical data in calculating the allowance for loan and lease losses. Consumer real estate loans are charged off to the estimated fair value of the underlying collateral, less estimated selling costs, no later than 150 days past due. Additional review of the fair value, less estimated costs to sell, compared with the recorded value occurs upon foreclosure and additional charge-offs are recorded if necessary. Commercial loans, leasing and equipment finance loans and leases and inventory finance loans that are considered collateral dependent are charged off to estimated fair value, less estimated selling costs when it becomes probable, based on current information and events, that all principal and interest amounts will not be collectible in accordance with their contractual terms. Auto finance loans will be charged off in full no later than 120 days past due, unless repossession is reasonably assured and in process, in which case the loan would be charged off to the fair value of the collateral, less estimated selling costs. Consumer real estate and auto finance loans in bankruptcy status may be charged down to the fair value of the collateral, less estimated selling costs, within 60 days past due based on specific criteria. Deposit account overdrafts are reported in other loans. Net losses on uncollectible overdrafts are reported as net charge-offs in the allowance for loan and lease losses within 60 days from the date of overdraft. Loans that are not collateral dependent are charged off when deemed uncollectible based on specific facts and circumstances. The amount of the allowance for loan and lease losses significantly depends on management's estimates of variables affecting valuation, appraisals of collateral, evaluations of performance and status and the amounts and timing of future cash flows expected to be received. Such estimates, appraisals, evaluations and cash flows may be subject to frequent adjustments due to changing economic prospects of borrowers, lessees or properties. These estimates are reviewed periodically and adjustments, if necessary, are recorded in the provision for credit losses in the periods in which they become known. See Note 7. Allowance for Loan and Lease Losses and Credit Quality Information for further information on the allowance for loan and lease losses. Income Taxes Income taxes are accounted for using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis carrying amounts. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recorded in income tax expense in the Consolidated Statements of Income in the period in which the enactment date occurs. If current period income tax rates change, the impact on the annual effective income tax rate is applied year to date in the period of enactment. The determination of current and deferred income taxes is a critical accounting estimate that is based on complex analyses of many factors, including interpretation of income tax laws, the evaluation of uncertain tax positions, differences between the tax and financial reporting bases of assets and liabilities (temporary differences), estimates of amounts due or owed, the timing of reversals of temporary differences and current financial accounting standards. Additionally, there can be no assurance that estimates and interpretations used in determining income tax assets or liabilities will not be challenged by taxing authorities. Actual results could differ significantly from the estimates and tax law interpretations used in determining the current and deferred income tax assets and liabilities. 69 In the preparation of income tax returns, tax positions are taken based on interpretation of income tax laws for which the outcome is uncertain. Management periodically reviews and evaluates the status of uncertain tax positions and makes estimates of amounts ultimately due or owed. The benefits of tax positions are recorded in income tax expense in the Consolidated Statements of Income net of the estimates of ultimate amounts due or owed, including any applicable interest and penalties. Changes in the estimated amounts due or owed may result from closing of the statute of limitations on tax returns, new legislation, clarification of existing legislation through government pronouncements, judicial action and through the examination process. TCF's policy is to report interest and penalties, if any, related to unrecognized tax benefits in income tax expense in the Consolidated Statements of Income. See Note 14. Income Taxes for further information on income taxes. Other Significant Accounting Policies Securities Held to Maturity Securities held to maturity are carried at cost and adjusted for amortization of premiums or accretion of discounts using a level yield method; however, transfers of securities available for sale to securities held to maturity are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of each transfer is retained in accumulated other comprehensive income (loss) and in the carrying value of the held to maturity investment security. Such amounts are then amortized over the remaining life of the transferred security as an adjustment of the yield on those securities. TCF periodically evaluates securities held to maturity for other than temporary impairment. Declines in value considered other than temporary, if any, would be recorded in non-interest income within gains (losses) on securities, net. See Note 5. Securities Available for Sale and Securities Held to Maturity for further information on securities held to maturity. Securities Available for Sale Securities available for sale are carried at fair value with the unrealized gains or losses net of related deferred income taxes reported within accumulated other comprehensive income (loss). The cost of securities sold is determined on a specific identification basis and gains or losses on sales of securities available for sale are recognized on trade dates. Discounts and premiums on securities available for sale are amortized using a level yield method over the expected life of the security, or to the earliest call date for premiums on securities with call features. TCF evaluates securities available for sale for other than temporary impairment on a quarterly basis. Declines in the value of securities available for sale that are considered other than temporary are recorded in non-interest income within gains (losses) on securities, net. See Note 5. Securities Available for Sale and Securities Held to Maturity for further information on securities available for sale. Loans and Leases Held for Sale Loans and leases designated as held for sale are generally carried at the lower of cost or fair value. Any amount by which cost exceeds fair value is initially recorded as a valuation allowance and subsequently reflected in the gain or loss on sale when sold. Certain other loans held for sale are recorded at fair value under the elected fair value option. From time to time, management identifies and designates, primarily consumer real estate, loans held in the loan portfolios for sale. These loans are transferred to loans and leases held for sale at the lower of cost or fair value at the time of transfer net of any associated allowance for loan and lease losses. Loans and Leases Loans and leases are reported at historical cost including net direct fees and costs associated with originating and acquiring loans and leases. The net direct fees and costs for sales-type leases are offset against revenues recorded at the commencement of sales-type leases. Discounts and premiums on acquired loans, net direct fees and costs, unearned discounts and finance charges, and unearned lease income are amortized to interest income using methods that approximate a level yield over the estimated remaining lives of the loans and leases. Net direct fees and costs on all lines of credit are amortized on a straight line basis over the contractual life of the line of credit and adjusted for payoffs. Net deferred fees and costs on consumer real estate lines of credit are amortized to fees and service charges. See Note 6. Loans and Leases for further information on loans and leases. 70   TCF acquires loans and leases through business combinations and purchases of loan and lease portfolios. These loans and leases are recorded at fair value at acquisition and the fair value discount or premium is recognized as an adjustment to yield over the remaining life of each loan or lease. Loans are considered purchased credit impaired ("PCI") loans if it is probable at acquisition that all contractually required payments will not be collected. Upon acquisition, the acquired PCI loans are recorded at fair value without a corresponding allowance for loan losses as the non- accretable discount is adequate to absorb expected remaining credit losses. The excess of expected cash flows to be collected over the initial fair value of the acquired portfolios is referred to as the accretable yield and is accreted into interest income over the estimated life of the acquired portfolios using the effective yield method. The accretable yield is affected by changes in interest rate indices for variable-rate acquired portfolios, changes in prepayment assumptions and changes in the expected principal and interest payments over the estimated life of the loan. These acquired loans are classified as accruing and interest income continues to be recognized unless expected credit losses exceed the non-accretable discount. Non-accrual Loans and Leases Loans and leases are generally placed on non-accrual status when the collection of interest or principal is 90 days or more past due, unless, in the case of commercial loans, they are well secured and in the process of collection. Delinquent consumer real estate junior lien loans are placed on non-accrual status when there is evidence that the related third-party first lien mortgage may be 90 days or more past due, or foreclosure, charge-off or collection action has been initiated. TDR loans are placed on non-accrual status prior to the past due thresholds outlined above if repayment under the modified terms is not likely after performing a well-documented credit analysis. Loans on non-accrual status are generally reported as non-accrual loans until there is sustained repayment performance for six consecutive months, with the exception of loans not reaffirmed upon discharge under Chapter 7 bankruptcy, which remain on non-accrual status until a well-documented credit analysis indicates full repayment of the remaining pre-discharged contractual principal and interest is likely. Income on these loans is recognized on a cash basis when there is sustained repayment performance for nine or 12 consecutive months based on the credit evaluation and the loan is not more than 60 days delinquent. Generally, when a loan or lease is placed on non-accrual status, uncollected interest accrued in prior years is charged off against the allowance for loan and lease losses and interest accrued in the current year is reversed against interest income. For non-accrual leases that have been discounted with third-party financial institutions on a non-recourse basis, the related liability is also placed on non-accrual status. Interest payments received on loans and leases in non-accrual status are generally applied to principal unless the remaining principal balance has been determined to be fully collectible, in which case interest income is recognized on a cash basis. See Note 7. Allowance for Loan and Lease Losses and Credit Quality Information for further information on non-accrual loans and leases. Lease Financing TCF provides various types of commercial lease financing that are classified for accounting purposes as direct financing, sales-type or operating leases. Leases that transfer substantially all of the benefits and risks of ownership to the lessee are classified as direct financing or sales-type leases and are included in loans and leases. Direct financing and sales-type leases are carried at the combined present value of future minimum lease payments and lease residual values. The determination of lease classification requires various judgments and estimates by management including the fair value of the equipment at lease inception, useful life of the equipment under lease, estimate of the lease residual value and collectability of minimum lease payments. Sales-type leases generate dealer profit, which is recognized at lease inception by recording lease revenue net of lease cost. Lease revenue consists of the present value of the future minimum lease payments. Lease cost consists of the leased equipment's book value, less the present value of its residual. Interest income on direct financing and sales-type leases is recognized using methods that approximate a level yield over the fixed, non-cancelable term of the lease. TCF receives pro rata rent payments for the interim period until the lease contract commences and the fixed, non-cancelable lease term begins. TCF recognizes these interim payments in the month they are earned and records the income in interest income. Management has policies and procedures in place for the determination of lease classification and review of the related judgments and estimates for all lease financings. 71 Some lease financings include a residual value component, which represents the estimated fair value of the leased equipment at the expiration of the initial term of the transaction. The estimation of residual values involves judgment regarding product and technology changes, customer behavior, shifts in supply and demand and other economic assumptions. TCF reviews residual assumptions in the portfolio at least annually and records impairment, if necessary, which is charged to non-interest expense in the periods in which it becomes known. TCF may sell minimum lease payments primarily as a credit risk reduction tool to third-party financial institutions at fixed rates on a non-recourse basis with its underlying equipment as collateral. For those transactions that achieve sale treatment, the related lease cash flow stream and the non-recourse financing are derecognized. For those transactions that do not achieve sale treatment, the underlying lease remains on TCF's Consolidated Statements of Financial Condition and non-recourse debt is recorded in the amount of the proceeds received. TCF retains servicing of these leases and bills, collects and remits funds to the third-party financial institution. Upon default by the lessee, the third-party financial institutions may take control of the underlying collateral which TCF would otherwise retain as residual value. Leases that do not transfer substantially all benefits and risks of ownership to the lessee are classified as operating leases. Such leased equipment and related initial direct costs are included in other assets on the Consolidated Statements of Financial Condition and depreciated on a straight-line basis over the term of the lease to its estimated salvage value. Depreciation expense is recorded as operating lease expense and included in non-interest expense. Operating lease rental income is recognized when it is due and is reflected as a component of non-interest income. An allowance for lease losses is not provided on operating leases. Premises and Equipment Premises and equipment, including leasehold improvements, are carried at cost and are depreciated or amortized on a straight-line basis over estimated useful lives of owned assets and for leasehold improvements over the estimated useful life of the related asset or the lease term, whichever is shorter. Maintenance and repairs are charged to expense as incurred. Rent expense for leased land with facilities is recognized in occupancy and equipment expense. Rent expense for leases with free rent periods or scheduled rent increases is recognized on a straight-line basis over the lease term. See Note 8. Premises and Equipment, Net for further information on premises and equipment. Other Real Estate Owned and Repossessed and Returned Assets 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 of the collateral less estimated selling costs at the time of transfer to real estate owned or 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. The fair value of repossessed and returned assets is based on available pricing guides, auction results or price opinions, less estimated selling costs. Any carrying amount in excess of the fair value less estimated selling costs is charged off to the allowance for loan and lease losses upon transfer. Subsequently, if the fair value of an asset, less the estimated costs to sell, declines to less than the carrying amount of the asset, the shortfall is recognized in the period in which it becomes known and is included in foreclosed real estate and repossessed assets, net expense. Operating expenses of properties and recoveries on sales of other real estate owned are also recorded in non-interest expense within foreclosed real estate and repossessed assets, net expense. Operating revenue from foreclosed property is included in other non-interest income. See Note 7. Allowance for Loan and Lease Losses and Credit Quality Information for further information on other real estate owned and repossessed and returned assets. Investments in Affordable Housing Limited Liability Entities TCF has investments in affordable housing limited liability entities that either operate qualified affordable housing projects or invest in other limited liability entities formed to operate affordable housing projects, which TCF generally accounts for under the proportional amortization method. However, depending on circumstances, the effective yield, equity or cost methods may be utilized. The amount of the investments, along with any unfunded equity contributions that are unconditional and legally binding, are recorded in other assets. A liability for the unfunded equity contributions is recorded in accrued expenses and other liabilities. The tax credits and amortization of the investments are reflected in the Consolidated Statements of Income as a component of income tax expense. See Note 10. Investments in Affordable Housing Limited Liability Entities for further information on investments in affordable housing limited liability entities. 72 Interest-only Strips TCF sells fixed- or variable-rate consumer real estate and auto finance loans with or without interest-only strips to third party financial institutions. For those transactions that achieve sale treatment, the underlying loans are removed from TCF's Consolidated Statements of Financial Condition. The Company may receive as part of the sale consideration an interest in the future cash flows of borrower loan payments, known as an interest-only strip. The interest-only strip is recorded at fair value in other assets with the unrealized gains or losses net of deferred income taxes reported within accumulated other comprehensive income (loss). The fair value of the interest-only strip represents the present value of future cash flows expected to be received by TCF. After initial recording of the interest- only strip, the accretable yield is measured as the difference between the initial investment, or fair value, and the cash flows expected to be collected. The accretable yield is amortized into interest income over the life of the interest-only strip using the effective yield method. The expected cash flows are evaluated quarterly to determine if they have changed from previous projections. Declines in the value of interest-only strips that are considered other than temporary are recorded in other non-interest expense. See Note 6. Loans and Leases for further information on interest-only strips. Goodwill and Other Intangible Assets All assets and liabilities acquired in purchase acquisitions, including other intangibles, are initially recorded at fair value. Goodwill is recorded when the purchase price of an acquisition is greater than the fair value of net assets, including identifiable intangible assets. Goodwill is not amortized, but assessed for impairment on at least an annual basis at the reporting unit level. Interim impairment analysis may be required if events occur or circumstances change that would more likely than not reduce a reporting unit's fair value below its carrying amount. Other intangible assets are amortized on a straight-line basis or accelerated method over their estimated useful lives and are subject to impairment if events or circumstances indicate a possible inability to realize their carrying amounts. When testing for goodwill impairment, TCF has the option to perform a qualitative assessment of goodwill. TCF may also elect to perform a quantitative test without first performing a qualitative analysis. If the qualitative assessment is performed and TCF concludes it is more likely than not that a reporting unit's fair value is less than its carrying amount, a quantitative analysis is performed. Quantitative valuation methodologies primarily include a discounted cash flow analysis in determining the fair value of reporting units. If the fair value is less than the carrying amount, additional analysis is required to measure the amount of impairment. Impairment losses, if any, are recorded as a charge to non-interest expense and an adjustment to the carrying value of goodwill. Other intangible assets are reviewed for impairment whenever events or changes in circumstances indicate their carrying amount may not be recoverable. Impairment is indicated if the sum of the undiscounted estimated future net cash flows is less than the carrying value of the intangible asset. Impairment losses, if any, permanently reduce the carrying value of the other intangible assets. See Note 9. Goodwill and Other Intangible Assets for further information on intangible assets. Derivative Instruments All derivative instruments are recognized at fair value within other assets or accrued expenses and other liabilities on the Consolidated Statements of Financial Condition. The Company's derivative instruments may be subject to master netting arrangements and collateral arrangements and qualify for offset in the Consolidated Statements of Financial Condition. A master netting arrangement with a counterparty creates a right of offset for amounts due to and from that same counterparty that is enforceable in the event of a default or bankruptcy. The Company's policy is to recognize amounts subject to master netting arrangements and collateral arrangements on a net basis in 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 exposure to changes in the fair value of an asset or liability due to changes in market risk ("fair value 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. 73 Fair Value Hedges TCF Bank entered into an interest rate swap agreement related to its contemporaneously issued subordinated debt, which settles 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 the three-month London InterBank Offered Rate plus a fixed number of basis points on the $150.0 million notional amount through February 27, 2025, the maturity date of the subordinated debt. In exchange, TCF Bank will receive 4.60% fixed-rate interest on the $150.0 million notional amount 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, as well as the offsetting changes in fair value of the hedged debt, are reflected in other non-interest income. Net Investment Hedges  Forward foreign exchange contracts, which generally settle within 35 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. 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. Derivatives Not Designated as Hedges  Certain of TCF's forward foreign exchange contracts are not designated as hedges and are generally settled within 35 days. Changes in the fair value of these forward foreign exchange contracts are reflected in other non-interest expense. TCF executes interest rate contracts with commercial banking customers to facilitate their respective risk management strategies. Those interest rate contracts are simultaneously hedged with offsetting interest rate contracts that TCF executes with a third party and generally settles through a central clearing house, minimizing TCF's net risk exposure. As the interest rate contracts do not meet hedge accounting requirements, changes in the fair value of both the customer contracts and the offsetting contracts are reflected in other non-interest income. These contracts have original fixed maturity dates ranging from three to 10 years. TCF enters into interest rate lock commitments in conjunction with the sale of 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 gains on sales of consumer real estate loans, net. 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 other non-interest expense. See Note 20. Derivative Instruments for further information on derivative instruments. Stock-based Compensation The fair value of restricted stock, stock options and restricted stock units is determined on the date of grant and amortized to compensation expense, with a corresponding increase to additional paid-in capital, over the longer of the service period or performance period, but in no event beyond an employee's retirement date or date of employment termination. For performance-based restricted stock or stock units, TCF estimates the degree to which performance conditions will be met to determine the number of shares or units that will vest and the related compensation expense. Compensation expense is adjusted in the period such estimates change. Non- forfeitable dividends, if any, paid on shares of restricted stock are recorded to retained earnings for shares that are expected to vest and to compensation expense for shares that are not expected to vest. Income tax benefits (detriments) related to stock compensation, where the fair value on vesting or exercise of the award is greater than (less than) the grant date value less any proceeds on exercise, are recognized in income tax expense. See Note 17. Stock Compensation for further information on stock-based compensation. 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. 74 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 and restricted stock units 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. See Note 22. Earnings Per Common Share for further information on earnings per share. New Accounting Pronouncements Adopted During the fourth quarter of 2017, the Company adopted Accounting Standards Update ("ASU") No. 2018-02: Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows reclassification of certain stranded income tax effects in accumulated other comprehensive income to retained earnings resulting from the Tax Cuts and Jobs Act of 2017 ("Tax Reform"). As a result of the adoption, the Company recorded a reclassification from accumulated other comprehensive income (loss) to retained earnings of $3.4 million. During the second quarter of 2017, the Company adopted ASU No. 2017-08: Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities, which clarifies the premium amortization period on purchased callable debt securities should be to the earliest call date, rather than the contractual maturity date. The adoption of this ASU was on a modified retrospective basis and required any adjustments as a result of the adoption during an interim period to be reflected as of January 1, 2017. The adoption of this ASU did not have an impact on our consolidated financial statements. Effective January 1, 2017, the Company adopted ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which simplified several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. As a result of the adoption, the Company recorded a cumulative effect reduction to the opening balance of retained earnings of $1.3 million and a corresponding increase to additional paid-in capital. This cumulative effect adjustment to retained earnings was related to a policy election to account for forfeitures as they occur, thereby eliminating the need for an estimated forfeiture reserve against future cancellations. The adoption of this ASU on a prospective basis requires that tax benefits related to stock compensation be recorded to income tax expense, instead of to additional paid-in capital. The Company elected the prospective basis regarding the presentation of stock compensation tax (expense) benefit in the Consolidated Statement of Cash Flows as an operating activity and as a result prior periods were not adjusted. Effective January 1, 2017, the Company adopted ASU Nos. 2016-05, Derivatives and Hedging (Topic 815): Effects of Derivative Contract Novations on Existing Hedge Accounting Relationships, 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments and 2016-07, Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting. The adoption of these ASUs did not have an impact on our consolidated financial statements. Note 3.  Cash and Due from Banks At December 31, 2017 and 2016, TCF Bank was required by Federal Reserve regulations to maintain reserves of $107.0 million and $103.7 million, respectively, in cash on hand or at the Federal Reserve Bank. TCF maintains cash balances that are restricted as to their use in accordance with certain contractual agreements primarily related to the servicing of auto finance loans. Cash payments received on loans serviced for third parties are generally held in separate accounts until remitted. TCF may also retain cash balances for collateral on certain borrowings, forward foreign exchange contracts, interest rate contracts and other contracts. TCF maintained restricted cash totaling $36.5 million and $51.3 million at December 31, 2017 and 2016, respectively. TCF had cash held in interest-bearing accounts of $324.2 million and $326.5 million at December 31, 2017 and 2016, respectively. 75     Note 4. Investments Investments were as follows: (In thousands) Federal Home Loan Bank stock, at cost Federal Reserve Bank stock, at cost Total investments At December 31, 2017 2016 $ $ 45,021 $ 37,623 82,644 $ 37,022 37,692 74,714 The investments in Federal Home Loan Bank ("FHLB") stock are required investments related to TCF's membership in and current borrowings from the FHLB of Des Moines. TCF's investments in the FHLB of Des Moines could be adversely impacted by the financial operations of the Federal Home Loan Banks and actions of their regulator, the Federal Housing Finance Agency. The amount of Federal Reserve Bank stock that TCF Bank is required to hold is based on TCF Bank's capital structure. TCF periodically evaluates investments for other than temporary impairment. There was no impairment of these investments in 2017, 2016 or 2015. The yield on these investments, which have no stated contractual maturity, was 2.96% and 2.59% at December 31, 2017 and 2016, respectively. Note 5.  Securities Available for Sale and Securities Held to Maturity Securities were as follows: 2017 2016 At December 31, Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value $ 908,189 $ 308 $ 13,812 $ 894,685 $ 827,722 $ 423 $ 17,254 $ 810,891 (In thousands) Securities available for sale: Mortgage-backed securities: U.S. Government sponsored enterprises and federal agencies Other 6 — — 6 18 — — 18 Obligations of states and political subdivisions Total securities available for sale Securities held to maturity: Mortgage-backed securities: U.S. Government sponsored enterprises and federal agencies 810,159 7,967 3,799 814,327 628,972 394 16,840 612,526 $1,718,354 $ 8,275 $ 17,611 $ 1,709,018 $1,456,712 $ 817 $ 34,094 $1,423,435 $ 158,776 $ 4,462 $ 412 $ 162,826 $ 178,514 $ 3,072 $ 440 $ 181,146 Other securities 2,800 — — 2,800 2,800 — — 2,800 Total securities held to maturity $ 161,576 $ 4,462 $ 412 $ 165,626 $ 181,314 $ 3,072 $ 440 $ 183,946 At December 31, 2017 and 2016, mortgage-backed securities with a carrying value of $0.9 million and $7.5 million, respectively, were pledged as collateral to secure certain deposits and borrowings. We have assessed each security with unrealized losses included in the table above for credit impairment. As part of that assessment, we evaluated and concluded that we do not intend to sell any of the securities and that it is more likely than not that we will not be required to sell prior to recovery of the amortized cost. Unrealized losses on securities available for sale and securities held to maturity were primarily due to changes in interest rates. 76     Gains (losses) on securities, net was $0.2 million for 2017, compared with $(0.6) million and $(0.3) million for 2016 and 2015, respectively.

The aggregate amount of these loan and lease adjustments was $33.3 million and $54.1 million at December 31, 2017 and 2016, respectively. 78 Loan Sales The following tables summarize the net sales proceeds for consumer real estate and auto finance loans sold, the securitization receivable recorded, the interest-only strips received, the recorded investment in loans sold, including accrued interest, and the net gains, as applicable. TCF generally retains servicing on loans sold. Included in consumer real estate loans sold in 2017 were $71.2 million of non-accrual loans, which were sold servicing released. The auto finance securitizations included in 2016 and 2015 qualify for sale accounting and are executed by transferring the recorded investment to trusts. These trusts are considered variable interest entities due to their limited capitalization and special purpose nature. TCF has concluded it is not the primary beneficiary of the trusts and therefore, they are not consolidated. No servicing assets or liabilities related to consumer real estate or auto finance loans were recorded within TCF's Consolidated Statements of Financial Condition, as the contractual servicing fees are adequate to compensate TCF for its servicing responsibilities based on the amount demanded by the marketplace.

TCF recorded impairment charges on the auto finance interest-only strips of $0.5 million, $2.4 million and $0.9 million in 2017, 2016 and 2015, respectively. 79 TCF's agreements to sell auto and consumer real estate loans typically contain certain representations, warranties and covenants regarding the loans sold or securitized. These representations, warranties and covenants generally relate to, among other things, the ownership of the loan, the validity, priority and perfection of the lien securing the loan, accuracy of information supplied to the buyer or investor, the loan's compliance with the criteria set forth in the agreement, the manner in which the loans will be serviced, payment delinquency and compliance with applicable laws and regulations. These agreements generally require the repurchase of loans or indemnification in the event TCF breaches these representations, warranties or covenants and such breaches are not cured. In addition, some agreements contain a requirement to repurchase loans as a result of early payoffs by the borrower, early payment default of the borrower, or the failure to obtain valid title. During 2017, 2016 and 2015, losses related to repurchases pursuant to such representations, warranties and covenants were immaterial. The majority of such repurchases were of auto finance loans where TCF typically has contractual agreements with the automobile dealerships that originated the loans requiring the dealers to reimburse TCF for the cost of such repurchases. Leasing and Equipment Finance Portfolio The leasing and equipment finance portfolio consisted of $2.5 billion of leases and $2.3 billion of loans at December 31, 2017, compared with $2.3 billion of leases and $2.0 billion of loans at December 31, 2016. Future minimum lease payments receivable for direct financing, sales-type and operating leases as of December 31, 2017 were as follows: (In thousands) 2018 2019 2020 2021 2022 Thereafter Total $ 951,164 721,392 509,644 308,679 139,613 54,039 $ 2,684,531 Acquired Loans and Leases TCF acquires loans and leases through business combinations and purchases of loan and lease portfolios. TCF purchased loans and leases at fair value of $771.3 million and $193.6 million during 2017 and 2016, respectively. Included in loans and leases acquired during 2017 were $14.0 million of leasing and equipment finance PCI loans that TCF acquired on September 29, 2017. On the acquisition date, the leasing and equipment finance PCI loans had contractually required payments receivable of $24.0 million, expected cash flows of $16.6 million and a fair value (initial carrying amount) of $14.0 million. The $7.4 million difference between the contractually required payments receivable and the expected cash flows represents the non-accretable difference. The $2.6 million difference between the expected cash flows and fair value represented the initial accretable yield. At December 31, 2017, the outstanding balance of these PCI loans was $16.4 million.

Non-accrual loans and leases are those which management believes have a higher risk of loss. Delinquent balances are determined based on the contractual terms of the loan or lease. Loans and leases that are over 60 days delinquent have a higher potential to become non-accrual and generally are a leading indicator for future charge-off trends. TCF's accruing and non-accrual loans and leases were as follows: Current-59 Days Delinquent and Accruing 60-89 Days Delinquent and Accruing 90 Days or More Delinquent and Accruing Total Accruing Non-accrual Total At December 31, 2017 (In thousands) Consumer real estate: First mortgage lien $ 1,892,771 $ 4,073 $ 593 $ 1,897,437 $ 61,950 $ 1,959,387 Junior lien Total consumer real estate Commercial: Commercial real estate Commercial business Total commercial Leasing and equipment finance Inventory finance Auto finance Other Subtotal Portfolios acquired with deteriorated credit quality 2,837,767 4,730,538 2,744,500 809,907 3,554,407 4,726,339 2,735,430 3,183,196 22,506 18,952,416 10,283 1,268 5,341 — 1 1 4,272 191 6,078 3 15,886 361 — 593 — — — 2,117 17 2,999 6 5,732 1,200 2,839,035 4,736,472 2,744,500 809,908 3,554,408 4,732,728 2,735,638 3,192,273 22,515 21,274 83,224 6,785 — 6,785 17,089 4,116 7,366 2 2,860,309 4,819,696 2,751,285 809,908 3,561,193 4,749,817 2,739,754 3,199,639 22,517 18,974,034 118,582 19,092,616 11,844 — 11,844 Total $ 18,962,699 $ 16,247 $ 6,932 $ 18,985,878 $ 118,582 $ 19,104,460 Current-59 Days Delinquent and Accruing 60-89 Days Delinquent and Accruing 90 Days or More Delinquent and Accruing Total Accruing Non-accrual Total At December 31, 2016 (In thousands) Consumer real estate: First mortgage lien $ 2,177,746 $ 6,581 $ 2,144 $ 2,186,471 $ 106,125 $ 2,292,596 Junior lien Total consumer real estate Commercial: Commercial real estate Commercial business Total commercial Leasing and equipment finance Inventory finance Auto finance Other Subtotal Portfolios acquired with deteriorated credit quality 2,744,006 4,921,752 2,628,627 651,932 3,280,559 4,320,795 2,464,986 2,634,600 18,748 17,641,440 113 1,404 7,985 — — — 3,478 16 3,785 14 15,278 — — 2,144 — — — 1,045 39 2,317 6 5,551 — 2,745,410 4,931,881 2,628,627 651,932 3,280,559 4,325,318 2,465,041 2,640,702 18,768 46,346 152,471 2,791,756 5,084,352 5,564 355 5,919 10,880 5,134 7,038 3 2,634,191 652,287 3,286,478 4,336,198 2,470,175 2,647,740 18,771 17,662,269 181,445 17,843,714 113 — 113 Total $ 17,641,553 $ 15,278 $ 5,551 $ 17,662,382 $ 181,445 $ 17,843,827 Interest income recognized on loans and leases in non-accrual status and contractual interest that would have been recorded had the loans and leases performed in accordance with their original contractual terms were as follows: (In thousands) Contractual interest due on non-accrual loans and leases Interest income recognized on non-accrual loans and leases Unrecognized interest income Year Ended December 31, 2017 2016 2015 $ $ 15,009 $ 20,604 $ 2,982 4,152 12,027 $ 16,452 $ 21,459 4,305 17,154 83   Consumer real estate loans to customers currently involved in ongoing Chapter 7 or Chapter 13 bankruptcy proceedings which have not yet been discharged, dismissed or completed were as follows:  (In thousands) Consumer real estate loans to customers in bankruptcy: 0-59 days delinquent and accruing Non-accrual Total consumer real estate loans to customers in bankruptcy At December 31, 2017 2016 $ $ 7,324 $ 10,552 17,876 $ 13,675 21,372 35,047 Loan Modifications for Borrowers with Financial Difficulties  Included within loans and leases in the previous accruing and non-accrual loans and leases tables are certain loans that have been modified in order to maximize collection of loan balances.

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 December 31, 2017, $22.3 million, or 65.0%, were loans discharged in Chapter 7 bankruptcy that were not reaffirmed by the borrower, of which 70.0% were current. Of the non-accrual TDR balance at December 31, 2016, $47.4 million, or 65.9%, were loans discharged in Chapter 7 bankruptcy that were not reaffirmed, of which 82.2% were current. All eligible loans are re-aged to current delinquency status upon modification. The allowance on accruing commercial TDR loans was $0.6 million, or 4.6% of the outstanding balance, at December 31, 2017 and $1.1 million, or 5.6% of the outstanding balance, at December 31, 2016. No accruing commercial TDR loans were 60 days or more delinquent at December 31, 2017 or 2016. The allowance on accruing TDRs for the remaining classes of finance receivables was not material at December 31, 2017 and 2016. No accruing TDR loans for the remaining classes of finance receivables were 60 days or more delinquent at December 31, 2017 or 2016. Unfunded commitments to consumer real estate and commercial loans classified as TDRs were $0.9 million and $0.4 million at December 31, 2017 and 2016, respectively. At December 31, 2017 and 2016, no additional funds were committed to leasing and equipment finance, inventory finance or auto finance loans classified as TDRs. 84     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 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. Interest income on TDR loans is recognized based on the restructured terms. Unrecognized interest represents the difference between interest income recognized on accruing TDR loans and the contractual interest that would have been recorded under the original contractual terms. In 2017, unrecognized interest income for consumer real estate first mortgage lien accruing TDR loans and consumer real estate junior lien accruing TDR loans was $1.8 million and $0.6 million, respectively. In 2016, unrecognized interest income for consumer real estate first mortgage lien accruing TDR loans and consumer real estate junior lien accruing TDR loans was $2.0 million and $0.7 million, respectively. The average yield on consumer real estate accruing TDR loans for 2017 and 2016 was 4.2%, which compares to the original contractual average rate for the same periods of 6.7%. In 2015, unrecognized interest income for consumer real estate first mortgage lien accruing TDR loans and consumer real estate junior lien accruing TDR loans was $2.2 million and $0.8 million, respectively. The average yield for the same period on consumer real estate accruing TDR loans was 4.1%, which compares to the original contractual average rate of 6.7%.The unrecognized interest income for the remaining classes of finance receivables was not material for 2017, 2016 and 2015. TCF considers a loan to have defaulted when under the modified terms it becomes 90 or more days delinquent, has been transferred to non-accrual status, has been charged down or has been transferred to other real estate owned or repossessed and returned assets. The following table summarizes the TDR loans that defaulted during 2017, 2016 and 2015, that were modified during the respective reporting period or within one year of the beginning of the respective reporting period.

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

The decision to discontinue auto finance loan originations resulted in a goodwill impairment charge of $73.0 million related to the acquisition of Gateway One and an impairment charge of $0.4 million related to the customer base intangible asset attributable to Gateway One. The Gateway One goodwill and customer base intangible asset were fully impaired at December 31, 2017. There was no impairment of goodwill or the other intangible assets in 2016 or 2015. 88 On June 16, 2017, TCF Bank acquired 100% of the outstanding shares of Equipment Financing & Leasing Corporation ("EFLC"). EFLC provides operating leases and direct financing leases of material handling equipment primarily to Fortune 500 customers. TCF Bank paid $9.0 million in cash upon closing, recorded a liability of $5.9 million to be paid within three years and assumed $64.2 million of EFLC's debt that was subsequently paid off. Assets acquired consisted of $46.4 million of operating lease equipment, $5.9 million of direct financing leases, $21.3 million of amortizable intangible assets, $2.2 million related to goodwill and approximately $3.3 million of cash, other assets and other liabilities, net. The weighted-average amortization periods of the acquired program agreement, non-compete agreement and customer base intangibles were 15 years, five years and three years, respectively. The amortizable intangible assets are amortized on an accelerated method over their estimated useful lives. On December 15, 2017, TCF Bank acquired the assets of Rubicon Mortgage Advisors, LLC. TCF recorded an amortizable intangible asset of $3.0 million related to a non-compete agreement as part of the acquisition. The weighted- average amortization period of the acquired non-compete agreement was four years and is amortized on a straight- line basis over its estimated useful life.

Investments in Affordable Housing Limited Liability Entities Investments in affordable housing limited liability entities and unfunded commitments were as follows: (In thousands) Investments in affordable housing limited liability entities $ Accrued expenses and other liabilities - unfunded commitments At December 31, 2017 2016 82,399 $ 48,973 30,279 12,082 During 2017, 2016 and 2015, TCF recognized amortization expense with respect to its investments in affordable housing limited liability entities of $9.6 million, $4.8 million and $3.3 million, respectively, offset by tax credits and other benefits of $12.5 million, $7.1 million and $3.9 million, respectively. At December 31, 2017, the expected payments for unfunded affordable housing commitments will be payable in 2018 through 2021. At December 31, 2017 and 2016, six and four, respectively, of these investments in affordable housing limited liability entities were considered variable interest entities ("VIE"). These limited liability entities are not consolidated with TCF. At December 31, 2017 and 2016, the carrying amount of the VIE investments was $81.9 million and $29.8 million, respectively. The maximum exposure to loss on the VIE investments was $81.9 million and $29.8 million at December 31, 2017 and 2016, respectively, however the limited liability entity provides various guarantees to TCF including guaranteed minimum returns. These guarantees are backed by an investment grade credit-rated company, which further reduces the risk of loss. In addition to the guarantees, the investments are supported by the performance of the underlying real estate properties which also mitigates the risk of loss. 89 Note 11.  Deposits Deposits were as follows: (Dollars in thousands) Checking: Non-interest bearing Interest bearing Total checking Savings Money market Certificates of deposit  Total deposits Weighted- average Rate 2017 Amount At December 31, % of Total Weighted- average Rate 2016 Amount % of Total —% $ 3,671,915 20.0% —% $ 3,454,962 20.0% 0.01 0.01 0.09 0.47 1.14 0.38 2,628,212 6,300,127 5,287,606 1,764,998 4,982,271 14.4 34.4 28.8 9.6 27.2 $ 18,335,002 100.0% 0.01 0.01 0.03 0.61 1.06 0.36 2,554,189 6,009,151 4,719,481 2,421,467 4,092,423 14.9 34.9 27.4 14.0 23.7 $ 17,242,522 100.0% Annual maturities for certificates of deposit at December 31, 2017 were as follows: (In thousands) 2018 2019 2020 2021 2022 Thereafter Total $ 3,251,222 1,498,121 201,936 10,811 6,414 13,767 $ 4,982,271 The aggregate amount of certificates of deposit with balances equal to or greater than the Federal Deposit Insurance Corporation insurance limit of $250,000 was $735.7 million and $561.0 million at December 31, 2017 and 2016, respectively. 90 Note 12.  Short-term Borrowings Selected information for short-term borrowings (borrowings with an original maturity of less than one year) was as follows: (Dollars in thousands) Period end balance: 2017 At December 31, 2016 2015 Amount Rate Amount Rate Amount Rate Securities sold under repurchase agreements Line of Credit - TCF Commercial Finance Canada, Inc.

At December 31, 2017, $875.0 million of the FHLB advances outstanding were prepayable at TCF's option. 91       Note 14. Income Taxes Tax Reform was enacted on December 22, 2017, resulting in changes in U.S. corporate tax rates, business-related exclusions, deductions and credits. Enactment of Tax Reform requires TCF to reflect the changes associated with the law's provisions in its consolidated financial statements as of and for the year ended December 31, 2017. The law is complex and has extensive implications for TCF's federal, state and foreign current and deferred income taxes. As a result of Tax Reform, TCF has recorded a reasonable estimate of a net tax benefit of $130.7 million in its consolidated financial statements for the year ended December 31, 2017, primarily resulting from the re-measurement of the Company's estimated net deferred tax liability. Certain of these amounts are provisional in nature, as all the information necessary to record more precise amounts is not yet available, prepared or analyzed. Examples include information associated with TCF’s deemed repatriation tax; like-kind-exchange program; the timing of payments associated with certain liabilities; reports, tax forms and forecasts from various partnership investments; grantor letters and tax forms from various trusts; and the results of detailed analyses of information associated with several deferred tax items. TCF will obtain, prepare and analyze this information during the measurement period, up to and including the period in which it files its 2017 consolidated federal income tax return. TCF may adjust these provisional amounts during the measurement period as it obtains, prepares or analyzes this additional information. Applicable income taxes in the Consolidated Statements of Income were as follows: (In thousands) Year ended December 31, 2017: Federal State Foreign Total Year ended December 31, 2016: Federal State Foreign Total Year ended December 31, 2015: Federal State Foreign Total Current Deferred Total $ $ $ $ $ $ 14,384 $ (62,913) $ (48,529) 237 5,484 9,340 (156) 9,577 5,328 20,105 $ (53,729) $ (33,624) 66,810 $ 28,629 $ 11,402 5,350 4,425 (88) 95,439 15,827 5,262 83,562 $ 32,966 $ 116,528 73,579 $ 16,141 $ 9,255 5,252 4,637 8 89,720 13,892 5,260 88,086 $ 20,786 $ 108,872 Reconciliations to TCF's effective income tax rate from the statutory federal income tax rate of 35.00% were as follows: Federal income tax rate Increase (decrease) resulting from: Tax Reform effects, net Nondeductible goodwill impairment effect State income tax, net of federal tax Tax-exempt income Non-controlling interest tax effect State tax settlements, net of federal tax Stock compensation Investments in affordable housing limited liability entities Foreign tax effects Other, net Effective income tax rate 92 Year Ended December 31, 2017 2016 2015 35.00 % 35.00% 35.00% (53.29) — 10.43 3.92 (3.86) (1.45) (1.38) (1.15) (0.89) (0.67) (0.38) — — 3.04 (2.07) (0.99) 0.19 — (0.24) (0.50) 0.02 — — 2.87 (0.93) (0.97) (0.12) — (0.18) (0.53) (0.54) (13.72)% 34.45% 34.60% TCF considers its undistributed foreign earnings to be reinvested indefinitely. This position is based on management's determination that cash held in TCF's foreign jurisdictions is not needed to fund its U.S. operations and that it either has reinvested or has intentions to reinvest these earnings. While management currently intends to indefinitely reinvest all of TCF's foreign earnings, should circumstances or tax laws change, TCF may need to record additional income tax expense in the period in which such determination or tax law change occurs. As a result of Tax Reform, TCF recognized a $2.0 million charge related to U.S. federal income tax on the deemed repatriation of undistributed foreign earnings as of December 31, 2017. Due to the shift to a worldwide territorial tax regime as part of Tax Reform, future repatriations of foreign earnings will no longer be subject to U.S. federal income tax. However, these foreign earnings may be subject to foreign withholding taxes should they be distributed in the form of dividends. As of December 31, 2017, the estimated withholding taxes that could be due on these earnings was $3.6 million. Reconciliations of the changes in unrecognized tax benefits were as follows: (In thousands) Balance, beginning of period Increases for tax positions related to the current year Increases for tax positions related to prior years Decreases for tax positions related to prior years Settlements with taxing authorities Decreases related to lapses of applicable statutes of limitation At or For the Year Ended December 31, 2017 2016 2015 $ 4,690 $ 4,249 $ 4,649 200 86 (331) — — 546 627 (84) (525) (123) 323 — (157) (425) (141) Balance, end of period $ 4,645 $ 4,690 $ 4,249 The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $2.2 million and $1.6 million at December 31, 2017 and 2016, respectively. TCF recognizes increases and decreases for interest and penalties related to unrecognized tax benefits, where applicable, in income tax expense. TCF recognized approximately $0.6 million of tax benefit, $0.9 million of tax expense and $0.2 million of tax benefit in 2017, 2016 and 2015, respectively, related to interest and penalties. Interest and penalties of approximately $0.6 million and $1.2 million were accrued at December 31, 2017 and 2016, respectively. TCF's federal income tax returns are open and subject to examination for 2014 and later tax return years. TCF's various state income tax returns are generally open for 2013 and later tax return years based on individual state statutes of limitation. TCF's various foreign income tax returns are open and subject to examination for 2013 and later tax return years. Changes in the amount of unrecognized tax benefits within the next 12 months from normal expirations of statutes of limitation are not expected to be material. 93 TCF's deferred tax assets and deferred tax liabilities were as follows: (In thousands) Deferred tax assets: Allowance for loan and lease losses Stock compensation and deferred compensation plans Net operating losses Securities available for sale Accrued expense Other Deferred tax assets Valuation allowance Total deferred tax assets, net of valuation allowance Deferred tax liabilities: Lease financing Premises and equipment Loan fees and discounts Prepaid expenses Goodwill and other intangibles Other Total deferred tax liabilities Net deferred tax liabilities At December 31, 2017 2016 $ 41,339 $ 21,150 16,452 5,345 2,507 3,603 90,396 (14,267) 76,129 246,221 30,109 12,489 8,047 2,475 4,715 304,056 $ 227,927 $ 75,976 41,105 11,924 17,606 3,730 5,548 155,889 (10,377) 145,512 348,933 32,430 17,017 11,245 3,870 7,375 420,870 275,358 The net operating losses at December 31, 2017 consisted of state net operating losses that expire in 2018 through 2037. The valuation allowance at December 31, 2017 and 2016 principally applies to net operating losses that, in the opinion of management, are more likely than not to expire unutilized. However, to the extent that tax benefits related to these carryforwards are realized in the future, the reduction in the valuation allowance will reduce income tax expense. Note 15. Equity Preferred Stock Preferred stock was as follows: (In thousands) 7.50% Series A non-cumulative perpetual preferred stock 6.45% Series B non-cumulative perpetual preferred stock 5.70% Series C non-cumulative perpetual preferred stock Total preferred stock At December 31, 2017 2016 $ $ — $ 96,519 169,302 265,821 $ 166,721 96,519 — 263,240 At December 31, 2017 and 2016, there were 4,000,000 shares outstanding of the 6.45% Series B non-cumulative perpetual preferred stock of TCF Financial Corporation, par value $0.01 per share, with a liquidation preference of $25 per share (the "Series B Preferred Stock"). Dividends are payable on the Series B Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year at a per annum rate of 6.45%. TCF paid cash dividends to holders of the Series B Preferred Stock of $6.5 million in 2017, 2016 and 2015. The Series B Preferred Stock may be redeemed at TCF's option in whole or in part at any time. On January 30, 2018, TCF's Board of Directors approved the redemption of all outstanding shares of the Series B Preferred Stock on March 1, 2018. 94 At December 31, 2017, there were 7,000,000 depositary shares outstanding, each representing a 1/1000th ownership interest in a share of the 5.70% Series C non-cumulative perpetual preferred stock of TCF Financial Corporation, par value $0.01 per share, with a liquidation preference of $25,000 per share (equivalent to $25 per depositary share) (the "Series C Preferred Stock"). Dividends are payable on the Series C Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year, which commenced on December 1, 2017, at a per annum rate of 5.70%. TCF paid cash dividends to holders of the Series C Preferred Stock of $2.1 million in 2017. The Series C Preferred Stock may be redeemed at TCF's option in whole or in part on December 1, 2022 or on any dividend payment date thereafter. The Series C Preferred Stock was issued on September 14, 2017 for an aggregate public offering price of $175.0 million. Net proceeds of the offering to TCF, after deducting deferred stock issuance costs of $5.7 million, were $169.3 million. On October 16, 2017, TCF redeemed the 6,900,000 depositary shares, each representing a 1/1000th ownership interest in a share of the 7.50% Series A non-cumulative perpetual preferred stock of TCF Financial Corporation, par value $0.01 per share, with a liquidation preference of $25,000 per share (equivalent to $25 per depositary share) (the "Series A Preferred Stock") for $172.5 million using the net proceeds from the offering of its Series C depositary shares and additional cash on hand. Deferred stock issuance costs of $5.8 million originally recorded as a reduction to preferred stock upon the issuance of the Series A Preferred Stock were reclassified to retained earnings and resulted in a non- cash, one-time reduction to net income available to common stockholders utilized in the computation of earnings per common share and diluted earnings per common share for 2017. Dividends were payable on the Series A Preferred Stock if, as and when declared by TCF's Board of Directors on a non-cumulative basis on March 1, June 1, September 1 and December 1 of each year at a per annum rate of 7.50%. TCF paid cash dividends to holders of the Series A Preferred Stock of $11.3 million in 2017 and $12.9 million in both 2016 and 2015. Restricted Retained Earnings Retained earnings at TCF Bank at December 31, 2017 included approximately $134.4 million for which no provision for federal income taxes has been made. This amount represents earnings legally appropriated to thrift bad debt reserves and deducted for federal income tax purposes in prior years and is generally not available for payment of cash dividends or other distributions to stockholders. Future payments or distributions of these appropriated earnings could create a tax liability for TCF based on the amount of the distributions and the tax rates in effect at that time. Treasury Stock and Other Treasury stock and other were as follows: (In thousands) Treasury stock, at cost Shares held in trust for deferred compensation plans, at cost Total At December 31, 2017 2016 $ $ 10,265 $ 30,532 40,797 $ 1,102 48,317 49,419 TCF repurchased 446,464 shares of its common stock in 2017 at an average cost of $20.51 per share under its share repurchase program. These shares are recorded as treasury stock. No repurchases of common stock were made in 2016 or 2015. At December 31, 2017, TCF had approximately $140.8 million in aggregate value of shares remaining in its stock repurchase program authorized by TCF's Board of Directors. The cost of TCF common stock held in trust for TCF's deferred compensation plans, including the Executive, Senior Officer, Winthrop and Directors Deferred Compensation Plans, TCF Employees Deferred Stock Compensation Plan and the TCF 401K Supplemental Plan, is reported in a manner similar to treasury stock (that is, changes in fair value are not recognized) with a corresponding deferred compensation obligation reflected in additional paid-in capital. Upon resignation, death, disability or termination of a deferred compensation plan participant or based on other contractual requirements, the shares held in trust are distributed to the respective plan's participant or beneficiary, as applicable. See Note 17. Stock Compensation and Note 18. Employee Benefit Plans for further information on deferred compensation plans. 95 Non-controlling Interest in Subsidiaries TCF has a joint venture with The Toro Company ("Toro") called Red Iron Acceptance, LLC ("Red Iron"). Red Iron provides U.S. distributors and dealers and select Canadian distributors of the Toro® and Exmark® branded products with sources of financing. TCF and Toro maintain a 55% and 45% ownership interest, respectively, in Red Iron. As TCF has a controlling financial interest in Red Iron, its financial results are consolidated in TCF's financial statements. Toro's interest is reported as a non-controlling interest within equity. Warrants At December 31, 2017, TCF had 3,199,988 warrants outstanding with an exercise price of $16.93 per share, which expire on November 14, 2018. Upon the completion of the U.S. Department of the Treasury ("U.S. Treasury")'s secondary public offering of the warrants issued under the Capital Purchase Program ("CPP") in December 2009, the warrants became publicly traded on the New York Stock Exchange and now trade under the symbol "TCFWS". As a result, TCF has no further obligation to the federal government in connection with the CPP. Note 16.  Regulatory Capital Requirements TCF and TCF Bank are subject to minimum capital requirements administered by the federal banking regulators. Failure to meet minimum capital requirements can initiate certain mandatory, and possible additional discretionary, actions by the federal banking regulators that could have a material adverse effect on TCF. In general, TCF Bank may not declare or pay a dividend to TCF Financial in excess of 100% of its net retained earnings for the current year combined with its net retained earnings for the preceding two calendar years, which was $529.8 million at December 31, 2017, without prior approval of the Office of the Comptroller of the Currency ("OCC"). The OCC also has the authority to prohibit the payment of dividends by a national bank when it determines such payments would constitute an unsafe and unsound banking practice. TCF Bank's ability to make capital distributions in the future may require regulatory approval and may be restricted by its federal banking regulators. TCF Bank's ability to make any such distributions will also depend on its earnings and ability to meet minimum regulatory capital requirements in effect during future periods. In the future, these capital adequacy standards may be higher than existing minimum regulatory capital requirements. The Basel III capital standard phases in through 2019. Institutions not subject to the advanced approaches requirements were allowed to opt out of including components of accumulated other comprehensive income (loss) in common equity Tier 1 capital. TCF and TCF Bank made the one-time permanent election to not include accumulated other comprehensive income (loss) in regulatory capital. TCF and TCF Bank are subject to a capital conservation buffer. When fully phased-in on January 1, 2019, the Basel III capital standard will require TCF and TCF Bank to maintain a 2.5% capital conservation buffer, designed to absorb losses during periods of economic stress, composed entirely of common equity Tier 1 capital, on top of the minimum risk-weighted asset ratios, effectively resulting in minimum ratios for TCF Bank of (i) a common equity Tier 1 capital ratio of at least 7.0%, (ii) a Tier 1 risk-based capital ratio of at least 8.5% and (iii) a total risk-based capital ratio of at least 10.5%. Regulatory capital information for TCF and TCF Bank was as follows: TCF TCF Bank At December 31, At December 31, 2017 2016 2017 2016 Well-capitalized Standard Minimum Capital Requirement(1) (Dollars in thousands) Regulatory Capital: Common equity Tier 1 capital $ 2,242,410 $ 1,970,323 $ 2,409,027 $ 2,144,966 Tier 1 capital Total capital 2,522,178 2,889,323 2,248,221 2,635,925 2,426,854 2,837,374 2,162,128 2,583,512 Regulatory Capital Ratios: Common equity Tier 1 capital ratio 10.79% 10.24% 11.59% 11.14% 6.50% 4.50% Tier 1 risk-based capital ratio Total risk-based capital ratio Tier 1 leverage ratio 12.14 13.90 11.12 11.68 13.69 10.73 11.68 13.65 10.70 11.23 13.42 10.32 8.00 10.00 5.00 6.00 8.00 4.00 (1) Excludes capital conservation buffer of 1.25% and 0.625% as of December 31, 2017 and 2016. 96 Note 17.  Stock Compensation TCF maintains four stock compensation plans: (i) The TCF Financial 2015 Omnibus Incentive Plan ("Omnibus Incentive Plan"), (ii) the TCF Financial Incentive Stock Program ("Incentive Stock Program"), (iii) the Executive, Senior Officer, Winthrop and Directors Deferred Compensation Plans and (iv) the TCF Employees Deferred Stock Compensation Plan. Omnibus Incentive Plan and Incentive Stock Program The Omnibus Incentive Plan and the Incentive Stock Program were adopted to enable TCF to attract and retain key personnel. In April 2015, TCF stockholders approved the Omnibus Incentive Plan, which replaced the Incentive Stock Program. At December 31, 2017, there were 1,446,047 and 366,000 shares reserved for issuance under the Omnibus Incentive Plan and Incentive Stock Program, respectively. At December 31, 2017, there were 350,000 shares of performance-based restricted stock awards outstanding that will vest only if certain performance goals and service conditions are achieved. Failure to achieve the performance goals and service conditions will result in all or a portion of the shares being forfeited. Service-based restricted stock awards under either the Omnibus Incentive Plan or the Incentive Stock Program vest over periods from one to five years. Information about restricted stock awards was as follows: (Dollars in thousands) Unrecognized stock compensation expense Weighted-average amortization (years) At or For the Year Ended December 31, 2017 2016 2015 $ 17,944 $ 24,925 $ 25,919 1.6 1.6 2.1 At December 31, 2017, there were 360,988 performance-based restricted stock units granted under the Omnibus Incentive Plan that will vest only if certain performance goals are achieved. The performance-based restricted stock units are subject to TCF’s relative total stockholder return for a three-year measurement period, based on award date, as measured against TCF's peer group, which includes publicly-traded banks and thrift institutions with assets between $10 billion and $50 billion as selected by TCF's Compensation Committee. The number of restricted stock units granted was at target and the actual restricted stock units granted will depend on actual performance with a maximum total payout of 150% of target. Failure to achieve the performance goals will result in all or a portion of the restricted stock units being forfeited. None of the performance-based restricted stock units had vested as of December 31, 2017. The remaining weighted-average performance period of the restricted stock units was 1.7 years at December 31, 2017. Compensation expense for restricted stock awards and restricted stock units was as follows: (In thousands) Compensation expense Tax benefit recognized for stock compensation expense Year Ended December 31, 2017 2016 2015 $ 12,687 $ 8,715 $ 5,661 3,103 5,931 2,127 In 2008, TCF granted stock options under the Incentive Stock Program. These options generally become exercisable over a period of one to 10 years from the date of the grant and expire after 10 years. All outstanding options have a fixed exercise price equal to the market price of TCF common stock on the date of grant. No stock options have subsequently been granted under the Incentive Stock Program. TCF also has the ability to grant stock options under the Omnibus Incentive Plan. As of December 31, 2017, no stock options had been granted under the Omnibus Incentive Plan. The valuation assumptions for stock options granted in 2008 under the Incentive Stock Program were as follows: Expected volatility Weighted-average volatility Expected dividend yield Expected term (years) Risk-free interest rate 28.5 % 28.5 % 3.5 % 6.25 - 6.75 2.58 % - 2.91 % 97 TCF's restricted stock award and stock option transactions since December 31, 2014 under the Omnibus Incentive Plan and the Incentive Stock Program were as follows: Outstanding at December 31, 2014 2,858,494 $ 6.16 Restricted Stock Awards Shares Grant Date Fair Value Range Weighted- average Grant Date Fair Value 786,933 12.86 — — - (156,332) (216,009) 899,000 (230,486) (405,425) — — - 583,388 13.96 — — - (577,020) (902,880) - - - - - - 6.80 9.65 6.16 9.48 - - - - 6.16 9.65 7.73 7.73 9.36 7.73 - - - $ 16.02 $ 16.28 — 15.96 15.96 16.28 13.24 — 15.96 15.96 16.28 19.42 — 15.87 16.02 19.42 12.73 14.45 — 13.20 13.16 13.09 12.13 — 13.59 13.10 12.81 16.47 — 11.38 13.65 13.65 N.A.

Executive, Senior Officer, Winthrop and Directors Deferred Compensation Plans TCF maintains the aforementioned deferred compensation plans, which previously allowed both eligible employees and non-employee directors to defer a portion of certain payments, and, in some cases, grants of restricted stock. In October 2008, TCF terminated the employee plans and only the Directors plan remains active, which allows non-employee directors to defer up to 100% of their director fees and restricted stock awards. The amounts deferred under these plans are invested in TCF common stock or other publicly traded stocks, bonds or mutual funds. At December 31, 2017, the fair value of the assets in these plans totaled $15.7 million and included $12.0 million invested in TCF common stock, compared with a total fair value of $14.0 million, including $10.5 million invested in TCF common stock at December 31, 2016. The plans' assets invested in TCF common stock are held in trust and are included in treasury stock and other. See Note 15. Equity for further information on treasury stock and other. TCF Employees Deferred Stock Compensation Plan The TCF Employees Deferred Stock Compensation Plan is comprised of restricted stock awards issued to certain executives. The assets of this plan are solely held in TCF common stock with a fair value of $9.6 million and $35.6 million at December 31, 2017 and 2016, respectively. The plan's assets invested in TCF common stock are held in trust and are included in treasury stock and other. See Note 15. Equity for further information on treasury stock and other. Upon resignation, death, disability or termination of a deferred compensation plan participant or based on other contractual requirements, the plan participant's assets are distributed. 98   Note 18.  Employee Benefit Plans TCF maintains four employee benefit plans: (i) the TCF 401K Plan (the "401K"), (ii) the TCF 401K Supplemental Plan (the "SERP"), (iii) the TCF Cash Balance Pension Plan (the "Pension Plan") and (iv) the Postretirement Plan. TCF 401K Plan The 401K, a qualified 401(k) and employee stock ownership plan, allows participants to make contributions of up to 50% of their covered compensation on a tax-deferred basis, subject to the annual covered compensation limitation imposed by the Internal Revenue Service ("IRS"). Effective January 1, 2018, participants could make contributions of up to 50% of their covered compensation on a tax-deferred and/or after-tax basis, subject to the annual covered compensation limitation imposed by the IRS. TCF matches the contributions of all participants with TCF common stock at the rate of $1 per dollar for employees with one or more years of service up to a maximum company contribution of 5.0% of the employee's covered compensation subject to the annual covered compensation limitation imposed by the IRS. Employee contributions and matching contributions vest immediately. Prior to January 1, 2016 TCF matched the contributions of all participants with TCF common stock at the rate of 50 cents per dollar for employees with one through four years of service up to a maximum company contribution of 3.0% of the employee's covered compensation, 75 cents per dollar for employees with five through nine years of service up to a maximum company contribution of 4.5% of the employee's covered compensation and $1 per dollar for employees with 10 or more years of service up to a maximum company contribution of 6.0% of the employee's covered compensation, subject to the annual covered compensation limitation imposed by the IRS. Employee contributions vested immediately while the Company's matching contributions made prior to January 1, 2016 are subject to a graduated vesting schedule based on an employee's years of service with full vesting after five years. Employees have the opportunity to diversify and invest their account balance, including matching contributions, in various mutual funds or TCF common stock. At December 31, 2017, the fair value of the assets in the 401K totaled $346.8 million and included $164.9 million invested in TCF common stock. Dividends on TCF common shares held in the 401K reduce retained earnings and the shares are considered outstanding for computing earnings per share. The Company's matching contributions are expensed when earned. TCF's contributions to the 401K were $12.3 million, $12.6 million and $10.6 million in 2017, 2016 and 2015, respectively. TCF 401K Supplemental Plan The SERP, a non-qualified plan, allows certain employees to contribute up to 50% of their salary and bonus. TCF matching contributions to this plan totaled $1.2 million, $1.7 million and $1.0 million in 2017, 2016 and 2015, respectively. The Company made no other contributions to this plan, other than payment of administrative expenses. The amounts deferred under this plan are invested in TCF common stock or mutual funds. At December 31, 2017, the fair value of the assets in the plan totaled $52.7 million and included $26.0 million invested in TCF common stock, compared with a total fair value of $48.2 million, including $27.9 million invested in TCF common stock at December 31, 2016. The plan's assets invested in TCF common stock are held in trust and included in treasury stock and other. See Note 15. Equity for further information on treasury stock and other. TCF Cash Balance Pension Plan The Pension Plan is a qualified defined benefit plan covering eligible employees who are at least 21 years old and have completed a year of eligible service with TCF. Employees hired after June 30, 2004 are not eligible to participate in the Pension Plan. Effective March 31, 2006, TCF amended the Pension Plan to discontinue compensation credits for all participants. Interest credits will continue to be paid until participants' accounts are distributed from the Pension Plan. Each month TCF credits participants' accounts with interest on their account balance based on the five-year U.S. Treasury rate plus 25 basis points rounded to the nearest quarter point determined at the beginning of each year. All participant accounts are vested. The measurement of the projected benefit obligation, prepaid pension asset, pension liability and annual pension expense involves complex actuarial valuation methods and the use of actuarial and economic assumptions. Due to the long-term nature of the Pension Plan obligation, actual results may differ significantly from the actuarial-based estimates. Differences between estimates and actual experience are recorded in the year they arise. TCF closely monitors all assumptions and updates them annually. The Company does not consolidate the assets and liabilities associated with the Pension Plan. 99 Postretirement Plan TCF provides health care benefits for eligible retired employees. Effective January 1, 2000, TCF modified the Postretirement Plan for employees not yet eligible for benefits under the Postretirement Plan by eliminating the Company subsidy. The Postretirement Plan provisions for full-time and retired employees then eligible for these benefits were not changed. Employees retiring after December 31, 2009 are no longer eligible to participate in the Postretirement Plan. The Postretirement Plan is not funded. The information set forth in the following tables is based on current actuarial reports using the measurement date of December 31 for TCF's Pension Plan and Postretirement Plan. The funded statuses of the Pension Plan and the Postretirement Plan were as follows: (In thousands) Change in projected benefit obligation: Benefit obligation, beginning of period Interest cost on projected benefit obligation Actuarial (gain) loss Benefits paid Projected benefit obligation, end of period Change in fair value of plan assets: Fair value of plan assets, beginning of period Actual gain (loss) on plan assets Benefits paid TCF contributions Fair value of plan assets, end of period Funded status of plans, end of period Amounts recognized in the Consolidated Statements of Financial Condition: Prepaid (accrued) benefit cost, end of period Prior service cost included in accumulated other comprehensive income (loss) Total recognized asset (liability) Pension Plan Postretirement Plan Year Ended December 31, 2017 2016 2017 2016 $ 33,174 $ 35,953 $ 4,164 $ 4,570 1,138 765 (3,688) 31,389 39,377 1,174 (3,688) — 1,281 (625) (3,435) 33,174 40,914 1,898 (3,435) — 36,863 39,377 133 (248) (332) 3,717 — — (332) 332 — 151 (211) (346) 4,164 — — (346) 346 — $ $ $ 5,474 $ 6,203 $ (3,717) $ (4,164) 5,474 $ 6,203 $ (3,717) $ (4,164) — — (193) (239) 5,474 $ 6,203 $ (3,910) $ (4,403) The accumulated benefit obligation for the Pension Plan was $31.4 million and $33.2 million at December 31, 2017 and 2016, respectively. TCF's Pension Plan investment policy permits investments in cash, money market mutual funds, direct fixed income securities to include U.S. Treasury securities, U.S. Government-sponsored enterprises and indirect fixed income investment securities made in fund form (mutual fund or institutional fund) where the fund invests in fixed income securities in investment grade corporate credits, non-investment grade floating-rate bank loans and non-investment grade bonds. The fair value of Level 1 assets are based on prices obtained from independent pricing sources for the same assets traded in active markets. The fair value of the mortgage-backed securities categorized as Level 2 assets are based on prices obtained from independent pricing sources that are based on observable transactions of similar instruments, but not quoted markets. There were no assets that are valued on a recurring basis as Level 3 assets. 100 The balances of TCF's Pension Plan investments measured at fair value on a recurring basis were as follows: (In thousands) Level 1: Fixed income mutual funds Money market mutual funds Cash Level 2: Mortgage-backed securities Pension plan investments not classified in fair value hierarchy: Collective investment fund Total Pension Plan assets held in trust Pension Plan Year Ended December 31, 2017 2016 $ 26,473 $ 705 63 26,121 2,430 65 4,613 5,766 4,995 $ 36,849 $ 4,989 39,371 The changes recognized in accumulated other comprehensive income (loss) attributable to the Postretirement Plan were as follows: (In thousands) Accumulated other comprehensive income (loss) before tax, beginning of period Amortization of prior service credit (recognized in net periodic benefit cost) Accumulated other comprehensive income (loss) before tax, end of period Postretirement Plan Year Ended December 31, 2017 2016 2015 $ $ (239) $ (285) $ 46 46 (193) $ (239) $ (331) 46 (285) The Pension Plan does not have any accumulated other comprehensive income (loss).

N.A. N.A. N.A. Not Applicable. Prior service credits of TCF's Postretirement Plan of $46 thousand were included within accumulated other comprehensive income (loss) at December 31, 2017 and are expected to be recognized as components of net periodic benefit cost during 2018. The actuarial assumptions used in the Pension Plan valuation are reviewed annually. The expected long-term rate of return on plan assets is determined by reference to historical market returns and future expectations. The 10-year expected average return of the index consistent with the Pension Plan's current investment strategy was 2.0%, net of administrative expenses. A 1.0% difference in the expected return on plan assets would result in a $0.4 million change in net periodic pension expense. The assumptions used to determine the estimated benefit plan obligation for the Pension Plan and Postretirement Plan were as follows: Discount rate Health care cost trend rate assumed for next year Final health care cost trend rate Year that final health care trend rate is reached N.A. Not Applicable. Pension Plan Postretirement Plan Year Ended December 31, Year Ended December 31, 2017 2016 2017 2016 3.30% 3.60% N.A. N.A. N.A. N.A. N.A. N.A. 3.15% 5.7 4.5 2038 3.40% 5.8 4.5 2038 The discount rates used to determine the estimated benefit plan obligation were determined by matching estimated benefit cash flows to a yield curve derived from corporate bonds rated AA by either Moody's or Standard and Poor's. Bonds containing call or put provisions were excluded. The average estimated duration of benefit cash flows for TCF's Pension Plan and Postretirement Plan varied between 6.5 and 6.9 years. Assumed health care cost trend rates have an effect on the amounts reported for the Postretirement Plan. A 1.0% change in assumed health care cost trend rates would have the following effect: (In thousands) Effect on total service and interest cost components Effect on postretirement benefit obligations 1-Percentage-Point Increase Decrease $ 5 $ 119 (5) (161) For 2017, TCF is eligible to contribute up to $11.0 million to the Pension Plan until the 2017 federal income tax return extended due date under various IRS funding methods. During 2017, 2016 and 2015, TCF made no cash contributions to the Pension Plan. TCF does not expect to be required to contribute to the Pension Plan in 2018. TCF contributed $0.3 million, $0.3 million and $0.4 million to the Postretirement Plan in 2017, 2016 and 2015, respectively. TCF expects to contribute $0.5 million to the Postretirement Plan in 2018. TCF currently has no plans to pre-fund the Postretirement Plan in 2018. 102 The expected future benefit payments used to determine projected benefit obligations were as follows: (In thousands) 2018 2019 2020 2021 2022 2023 - 2027 Pension Plan Postretirement Plan $ 3,200 $ 3,342 2,842 2,405 2,377 9,844 454 428 402 376 351 1,387 Note 19. Financial Instruments with Off-Balance Sheet Risk TCF is a party to financial instruments with off-balance sheet risk, primarily to meet the financing needs of its customers. These financial instruments, which are issued or held for purposes other than trading, involve elements of credit and interest-rate risk in excess of the amounts recognized in the Consolidated Statements of Financial Condition. TCF's exposure to credit loss, in the event of non-performance by the counterparty to the financial instrument, for commitments to extend credit and standby letters of credit is represented by the contractual amount of the commitments. TCF uses the same credit policies in making these commitments as it does for making direct loans. TCF evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained is based on a credit evaluation of the customer. Financial instruments with off-balance sheet risk were as follows: (In thousands) Commitments to extend credit: Consumer real estate and other Commercial Leasing and equipment finance Total commitments to extend credit Standby letters of credit and guarantees on industrial revenue bonds Total At December 31, 2017 2016 $ $ 1,484,065 $ 1,425,585 1,033,973 126,249 2,644,287 12,992 898,809 125,648 2,450,042 8,782 2,657,279 $ 2,458,824 Commitments to Extend Credit Commitments to extend credit are agreements to lend provided there is no violation of any condition in the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a certain amount of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Collateral to secure any funding of these commitments predominantly consists of residential and commercial real estate mortgages. Standby Letters of Credit and Guarantees on Industrial Revenue Bonds Standby letters of credit and guarantees on industrial revenue bonds are conditional commitments issued by TCF guaranteeing the performance of a customer to a third party. These conditional commitments expire in various years through 2021. Collateral held consists primarily of commercial real estate mortgages. Since the conditions under which TCF is required to fund these commitments may not materialize, the cash requirements are expected to be less than the total outstanding commitments. 103 Note 20.  Derivative Instruments Derivative instruments were as follows: (In thousands) Derivative Assets: Derivatives designated as hedges: Interest rate contracts Derivatives not designated as hedges: Interest rate contracts Interest rate lock commitments Total derivative assets Derivative Liabilities: Derivatives designated as hedges: Forward foreign exchange contracts Derivatives not designated as hedges: Forward foreign exchange contracts Interest rate contracts Other contracts Interest rate lock commitments Total derivative liabilities (In thousands) Derivative Assets: Derivatives designated as hedges: Forward foreign exchange contracts Derivatives not designated as hedges: Forward foreign exchange contracts Interest rate contracts Interest rate lock commitments Total derivative assets Derivative Liabilities: Derivatives designated as hedges: Interest rate contracts Derivatives not designated as hedges: Forward foreign exchange contracts Interest rate contracts Other contracts Interest rate lock commitments Total derivative liabilities At December 31, 2017 Notional Amount Gross Amounts Recognized Gross Amounts Offset Net Amount Presented $ 150,000 $ 405 $ (405) $ — 169,377 17,974 1,392 223 (52) — $ 2,020 $ (457) $ 1,340 223 1,563 $ 77,879 $ 1,744 $ (1,744) $ — 330,928 423,006 13,804 41 4,619 1,688 615 — (4,282) (457) (615) — 337 1,231 — — $ 8,666 $ (7,098) $ 1,568 At December 31, 2016 Notional Amount Gross Amounts Recognized Gross Amounts Offset Net Amount Presented $ 61,760 $ 1,082 $ — $ 1,082 250,018 149,499 27,954 2,995 1,925 318 (1,439) (633) — $ 6,320 $ (2,072) $ $ 150,000 $ 1,320 $ (1,320) $ 115,336 149,499 13,804 2,947 469 1,936 619 21 (445) (1,332) (619) — $ 4,365 $ (3,716) $ 1,556 1,292 318 4,248 — 24 604 — 21 649 104     The pre-tax impact of derivative activity within the Consolidated Statements of Income and the Consolidated Statements of Comprehensive Income was as follows: (In thousands) Consolidated Statements of Income Fair value hedges: Interest rate contracts Non-derivative hedged items Not designated as hedges: Income Statement Location 2017 2016 2015 Year Ended December 31, Other non-interest income $ (609) $ (1,178) $ Other non-interest income 808 1,140 (142) 209 Forward foreign exchange contracts Other non-interest expense (15,748) (13,689) 74,292 Interest rate lock commitments Interest rate contracts Other contracts Net gain (loss) recognized Gains on sales of consumer real estate loans, net Other non-interest income Other non-interest expense Consolidated Statements of Comprehensive Income Net investment hedges: Forward foreign exchange contracts Net unrealized gain (loss) Other comprehensive income (loss) (73) (268) (311) (419) 71 (629) 431 4 — (16,201) $ (14,704) $ 74,794 (4,430) $ (4,430) $ (1,213) $ (1,213) $ 7,613 7,613 $ $ $ 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 December 31, 2017 and 2016, credit risk-related contingent features existed on forward foreign exchange contracts with a notional value of $39.8 million and $78.1 million, respectively. 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 $0.8 million and $1.6 million in additional collateral at December 31, 2017 and 2016, respectively. There were $0.4 million of forward foreign exchange contracts containing credit risk-related features in a net liability position at December 31, 2017 and none at December 31, 2016. At December 31, 2017, TCF had posted $7.6 million, $7.5 million and $1.4 million of cash collateral related to its interest rate contracts, forward foreign exchange contracts and other contracts, respectively. 105 Note 21.  Fair Value Disclosures TCF uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The Company's fair values are based on the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Securities available for sale, certain loans held for sale, interest-only strips, forward foreign exchange contracts, interest rate contracts, interest rate lock commitments, forward loan sales commitments, assets and liabilities held in trust for deferred compensation plans and other contracts are recorded at fair value on a recurring basis. From time to time we may be required to record at fair value other assets on a non-recurring basis, such as certain securities held to maturity, loans, goodwill, other intangible assets, other real estate owned, repossessed and returned assets and the securitization receivable. These non-recurring fair value adjustments typically involve application of lower of cost or fair value accounting or write-downs of individual assets. TCF groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the degree and reliability of estimates and assumptions used to determine fair value as follows: Level 1, which includes valuations that are based on prices obtained from independent pricing sources for the same instruments traded in active markets; Level 2, which includes valuations that are based on prices obtained from independent pricing sources that are based on observable transactions of similar instruments, but not quoted markets; and Level 3, for which valuations are generated from Company model-based techniques that use significant unobservable inputs. Such unobservable inputs reflect estimates of assumptions that market participants would use in pricing the asset or liability. The following is a discussion of the valuation methodologies used to record assets and liabilities at fair value on a recurring or non-recurring basis and for estimating fair value of financial instruments not recorded at fair value. Investments The carrying value of investments in FHLB stock and Federal Reserve Bank stock, categorized as Level 2, approximates fair value based on redemption at par value. Securities Held to Maturity Securities held to maturity consist primarily of securities of U.S. Government sponsored enterprises and federal agencies. The fair value of securities of U.S. Government sponsored enterprises and federal agencies, categorized as Level 2, is estimated using prices obtained from independent asset pricing services that are based on observable transactions, but not quoted markets. Management reviews the prices obtained from independent asset pricing services for unusual fluctuations and comparisons to current market trading activity. The fair value of other securities, categorized as Level 3, is estimated using probability of loss based on risk rating definitions. There is no observable secondary market for these securities. Securities Available for Sale Securities available for sale consist primarily of securities of U.S. Government sponsored enterprises and federal agencies, and obligations of states and political subdivisions. The fair value of these securities, categorized as Level 2, is recorded using prices obtained from independent asset pricing services that are based on observable transactions, but not quoted markets. Management reviews the prices obtained from independent asset pricing services for unusual fluctuations and comparisons to current market trading activity. Loans Held for Sale Loans held for sale are generally carried at the lower of cost or fair value. Estimated fair values are based on recent loan sale transactions and any available price quotes on loans with similar coupons, maturities and credit quality. Certain other loans held for sale are recorded at fair value under the elected fair value option. TCF relies on internal valuation models which utilize quoted investor prices to estimate the fair value of these loans. Loans held for sale are categorized as Level 3. Loans The fair value of loans, categorized as Level 3, is estimated based on discounted expected cash flows and recent sales of similar loans. The discounted cash flows include assumptions for prepayment estimates over each loan's remaining life, consideration of the current interest rate environment compared with the weighted-average rate of each portfolio, a credit risk component based on the historical and expected performance of each portfolio and a liquidity adjustment related to the current market environment. TCF also uses pricing data from recent sales of loans with similar risk characteristics as data points to validate the assumptions used in estimating the fair value of certain loans. 106 Loans for which repayment is expected to be provided solely by the value of the underlying collateral, categorized as Level 3 and recorded at fair value on a non-recurring basis, are valued based on the fair value of that collateral less estimated selling costs. Such loans include non-accrual impaired loans as well as certain delinquent non-accrual consumer real estate and auto finance loans. The fair value of the collateral is determined based on internal estimates and assessments provided by third-party appraisers. Interest-only Strips The fair value of interest-only strips, categorized as Level 3, represents the present value of future cash flows expected to be received by TCF on certain assets. TCF uses available market data, along with its own empirical data and discounted cash flow models, to arrive at the estimated fair value of its interest-only strips. The present value of the estimated expected future cash flows to be received is determined by using discount, loss and prepayment rates that TCF believes are commensurate with the risks associated with the cash flows and what a market participant would use. These assumptions are inherently subject to volatility and uncertainty and, as a result, the estimated fair value of the interest-only strips may fluctuate significantly from period to period. Derivative Instruments Forward Foreign Exchange Contracts TCF's forward foreign exchange contracts are currency contracts executed in over-the-counter markets and are recorded at fair value using a cash flow model that includes key inputs such as foreign exchange rates and an assessment of the risk of counterparty non-performance. The risk of counterparty non- performance is based on external assessments of credit risk. The fair value of these contracts, categorized as Level 2, is based on observable transactions, but not quoted markets. Interest Rate Contracts TCF executes interest rate contracts with commercial banking customers to facilitate their respective risk management strategies. Certain of these interest rate contracts are simultaneously hedged by offsetting interest rate contracts TCF executes with a third party, minimizing TCF's net interest rate risk exposure resulting from such transactions. TCF also has an interest rate swap agreement to convert its $150.0 million of fixed-rate subordinated notes to floating rate debt. These derivative instruments are recorded at fair value. The fair value of these interest rate contracts, categorized as Level 2, is determined using a cash flow model which considers the forward curve, the discount curve and credit valuation adjustments related to counterparty and/or borrower non-performance risk. Interest Rate Lock Commitments TCF's interest rate lock commitments are derivative instruments that are recorded at fair value using an internal valuation model that utilizes estimated rates of successful loan closings and quoted investor prices. While this model uses both Level 2 and 3 inputs, TCF has determined that the inputs significant in the valuation of these commitments fall within Level 3 and therefore they are categorized as Level 3. Other Contracts TCF has a swap agreement related to the sale of TCF's Visa Class B stock, categorized as Level 3. The fair value of the swap agreement is based on TCF's estimated exposure related to the Visa covered litigation through a probability analysis of the funding and estimated settlement amounts. Forward Loan Sales Commitments TCF enters into forward loan sales commitments to sell certain consumer real estate loans. The resulting loans held for sale are also recorded at fair value under the elected fair value option. TCF relies on internal valuation models to estimate the fair value of these instruments. The valuation models utilize estimated rates of successful loan closings and quoted investor prices. While these models use both Level 2 and 3 inputs, TCF has determined that the inputs significant in the valuation of these commitments fall within Level 3 and therefore they are categorized as Level 3. Other Real Estate Owned and Repossessed and Returned Assets The fair value of other real estate owned, categorized as Level 3, is based on independent appraisals, real estate brokers' price opinions or automated valuation methods, less estimated selling costs. Certain properties require assumptions that are not observable in an active market in the determination of fair value. The fair value of repossessed and returned assets is based on available pricing guides, auction results or price opinions, less estimated selling costs. Assets acquired through foreclosure, repossession or returned to TCF are initially recorded at the lower of the loan or lease carrying amount or fair value less estimated selling costs at the time of transfer to other real estate owned or repossessed and returned assets. Securitization Receivable TCF executed an auto finance loan securitization during the second quarter of 2016 with a related receivable representing a cash reserve account posted at the inception of the securitization. The fair value of the securitization receivable, categorized as Level 3, is estimated based on discounted cash flows using interest rates for borrowings of similar remaining maturities plus a spread based on management's judgment. 107 Assets and Liabilities Held in Trust for Deferred Compensation Plans Assets held in trust for deferred compensation plans include investments in publicly traded securities, excluding TCF common stock reported in treasury stock and other equity, and U.S. Treasury notes. The fair value of these assets, categorized as Level 1, is based on prices obtained from independent asset pricing services based on active markets. The fair value of the liabilities equals the fair value of the assets. 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. Financial Instruments with Off-Balance Sheet Risk The fair value of TCF's commitments to extend credit and standby letters of credit, categorized as Level 2, is estimated using fees currently charged to enter into similar agreements. Substantially all commitments to extend credit and standby letters of credit have floating interest rates and do not expose TCF to interest rate risk; therefore fair value is approximately equal to carrying value. The balances of assets and liabilities measured at fair value on a recurring and non-recurring basis were as follows: (In thousands) Recurring Fair Value Measurements: Securities available for sale: Mortgage-backed securities: Fair Value Measurements at December 31, 2017 Level 1 Level 2 Level 3 Total U.S. Government sponsored enterprises and federal agencies $ — $ 894,685 $ — $ 894,685 6 — 3,356 21,386 — 223 68 — 6 814,327 3,356 21,386 1,797 223 68 29,962 25,039 $ 1,765,810 — $ — 615 5 — 6,363 1,688 615 5 29,962 38,633 Other Obligations of states and political subdivisions Loans held for sale Interest-only strips Interest rate contracts(1) Interest rate lock commitments(1) Forward loan sales commitments — — — — — — — Assets held in trust for deferred compensation plans 29,962 — 814,327 — — 1,797 — — — Total assets Forward foreign exchange contracts(1) Interest rate contracts(1) Other contracts(1) Forward loan sales commitments Liabilities held in trust for deferred compensation plans Total liabilities Non-recurring Fair Value Measurements: Loans Other real estate owned: Consumer Commercial Repossessed and returned assets Total non-recurring fair value measurements $ $ $ $ $ $ $ 29,962 $ 1,710,809 — $ — — — 29,962 6,363 1,688 — — — 29,962 $ 8,051 $ 620 $ — $ — $ 72,287 $ 72,287 — — — — — 3,669 13,951 85 4,388 13,951 85 8,057 — $ 3,669 $ 90,711 $ 94,380 (1) As permitted under GAAP, TCF has elected to net derivative assets and derivative liabilities when a legally enforceable master netting agreement exists as well as the related cash collateral received and paid.

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 2017, 2016 or 2015. 109 The changes in Level 3 assets and liabilities measured at fair value on a recurring basis were as follows: (In thousands) Securities Available for Sale Loans Held for Sale Interest-only Strips Interest Rate Lock Commitments Other Contracts Forward Loan Sales Commitments Asset (liability) balance, December 31, 2014 $ 55 $ 3,308 $ 69,789 $ 285 $ (621) $ (23) Total net gains (losses) included in: Net income Sales Originations Principal paydowns / settlements Asset (liability) balance, December 31, 2015 Total net gains (losses) included in: Net income Other comprehensive income (loss) Sales Originations Principal paydowns / settlements Asset (liability) balance, December 31, 2016 Total net gains (losses) included in: Net income Other comprehensive income (loss) Sales Originations — — — (21) 34 — — — — (16) 18 — — — — (68) (289,751) 297,079 — 10,568 (48) — (343,949) 339,930 (3) 6,498 129 — (215,381) 212,509 6,960 — 7,495 (39,912) 44,332 2,980 159 — 22,620 (29,939) 40,152 3,939 (452) — 3,377 Principal paydowns / settlements (12) (399) (25,630) 431 — — — 716 — — — 316 (305) (419) (629) — — — — 297 — — — 315 (619) 288 — — — 265 96 — — — — 361 (74) (310) (298) — — — — — — — 314 — — — — 63 Asset (liability) balance, December 31, 2017 $ 6 $ 3,356 $ 21,386 $ 223 $ (615) $ Fair Value Option TCF Bank originates first mortgage lien loans in its primary banking markets and sells the loans through a correspondent relationship. TCF elected the fair value option for these loans. This election facilitates the offsetting of changes in fair values of the loans held for sale and the derivative financial instruments used to economically hedge them. The difference between the aggregate fair value and aggregate unpaid principal balance of these loans held for sale was as follows: (In thousands) Fair value carrying amount Aggregate unpaid principal amount Fair value carrying amount less aggregate unpaid principal At December 31, 2017 2016 $ $ 3,356 $ 3,268 88 $ 6,498 6,563 (65) Differences between the fair value carrying amount and the aggregate unpaid principal balance include changes in fair value recorded at and subsequent to funding and gains and losses on the related loan commitment prior to funding. No loans recorded under the fair value option were delinquent or on non-accrual status at December 31, 2017 or 2016. The net gain from initial measurement of the correspondent lending loans held for sale, any subsequent changes in fair value while the loans are outstanding and any actual adjustment to the gains realized upon sales of the loans totaled $4.9 million, $7.6 million and $6.3 million for 2017, 2016 and 2015, respectively, and are included in gains on sales of consumer real estate loans, net. This amount excludes the impact from the interest rate lock commitments and forward loan sales commitments which are also included in gains on sales of consumer real estate loans, net. 110   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 December 31, 2017 and 2016, based on relevant market information and information about the financial instruments. Fair value estimates are intended to represent the price at which an asset could be sold or a liability could be settled. However, given there is no active market or observable market transactions for many of the Company's financial instruments, the estimates of fair values are subjective in nature, involve uncertainties and include matters of significant judgment. Changes in assumptions could significantly affect the estimated values. The carrying amounts and estimated fair values of the Company's financial instruments, excluding short-term financial assets and liabilities as their carrying amounts approximate fair value, and excluding financial instruments recorded at fair value on a recurring basis, were as follows. This information represents only a portion of TCF's balance sheet and not the estimated value of the Company as a whole. Non-financial instruments such as the intangible value of TCF's branches and core deposits, leasing operations, goodwill, premises and equipment, and the future revenues from TCF's customers are not reflected in this disclosure. Therefore, this information is of limited use in assessing the value of TCF.

Consumer Banking is comprised of all of the Company's consumer-facing businesses and includes retail banking, consumer real estate and auto finance. Wholesale Banking is comprised of commercial lending, leasing and equipment finance, and inventory finance. Enterprise Services is comprised of (i) corporate treasury, which includes TCF's investment and borrowing portfolios and management of capital, debt and market risks; (ii) corporate functions, such as information technology, risk and credit management, bank operations, finance, investor relations, corporate development, legal and human capital management, that provide services to the operating segments; (iii) the Holding Company and (iv) eliminations. TCF evaluates performance and allocates resources based on each reportable segment's net income or loss. The reportable business segments follow GAAP as described in Note 1. Basis of Presentation, except for the accounting for intercompany interest income and interest expense, which are eliminated in consolidation, and presenting net interest income on a fully tax-equivalent basis. TCF generally accounts for inter-segment sales and transfers at cost. 114     Certain information for each of TCF's reportable segments, including reconciliations of TCF's consolidated totals, was as

subsidiary, TCF Bank. As a result, TCF Financial's cash flow and ability to make dividend payments to its preferred and common stockholders depend on the earnings of TCF Bank. The ability of TCF Bank to pay dividends or make other payments to TCF Financial is limited by its obligation to maintain sufficient capital and by other regulatory restrictions on dividends. At December 31, 2017, TCF Bank could pay a total of approximately $529.8 million in dividends to TCF Financial without prior regulatory approval. 117 Note 26.  Litigation Contingencies From time to time TCF is a party to legal proceedings arising out of its lending, leasing and deposit operations, including foreclosure proceedings and other collection actions as part of its lending and leasing collections activities. TCF may also be subject to regulatory examinations and enforcement actions brought by federal regulators, including the Securities and Exchange Commission, the Federal Reserve, the OCC and the Consumer Financial Protection Bureau ("CFPB") and TCF's federal regulators may impose sanctions on TCF for failures related to regulatory compliance. From time to time borrowers and other customers, and employees and former employees have also brought actions against TCF, in some cases claiming substantial damages. TCF and other financial services companies are subject to the risk of class action litigation. Litigation is often unpredictable and the actual results of litigation cannot be determined and therefore the ultimate resolution of a matter and the possible range of loss associated with certain potential outcomes cannot be established. Except as discussed below, based on our current understanding of TCF's pending legal proceedings, management does not believe that judgments or settlements arising from pending or threatened legal matters, individually or in the aggregate, would have a material adverse effect on the consolidated financial position, operating results or cash flows of TCF. On January 19, 2017, the CFPB filed a civil lawsuit against TCF Bank in the United States District Court for the District of Minnesota (the "Court"), captioned Consumer Financial Protection Bureau v. TCF National Bank, alleging violations of the Consumer Financial Protection Act ("CFPA") and Regulation E, §1005.17 in connection with TCF Bank's practices administering checking account overdraft program "opt-in" requirements from 2010 to early 2014. In its complaint, the CFPB seeks, among other relief, redress for consumers, injunctive relief and unspecified penalties. On September 8, 2017, the Court issued a ruling on the motion made by TCF Bank to dismiss the complaint of the CFPB. In its ruling, the Court granted TCF Bank's motion to dismiss the CFPB's Regulation E claims and also dismissed the CFPB's unfair, deceptive and abusive conduct claims under the CFPA for periods prior to July 21, 2011. The Court did not grant TCF Bank's motion to dismiss CFPA claims for periods on or after July 21, 2011. TCF Bank rejects the claims made by the CFPB in its complaint and intends to continue to vigorously defend against the CFPB's allegations. TCF has not accrued any amounts with respect to this matter because (i) TCF does not believe a loss is probable, (ii) TCF believes the Company has meritorious defenses to the claims made and (iii) the damages sought are unspecified and uncertain. Therefore, TCF is currently unable to reasonably estimate a range of potential loss, if any, relating to this matter. There is no assurance that the ultimate resolution of this lawsuit will not have a material adverse effect on the consolidated financial position, operating results or cash flows of TCF. 118 Note 27.  Accumulated Other Comprehensive Income (Loss) The components of other comprehensive income (loss) and the related tax effects were as follows: (In thousands) Year Ended December 31, 2017: Net unrealized gains (losses) on securities available for sale and interest-only strips: Before Tax Tax Effect Net of Tax Unrealized gains (losses) arising during the period $ 24,244 $ (8,857) $ 15,387 Reclassification of net (gains) losses from accumulated other comprehensive income (loss) Net unrealized gains (losses) Net unrealized gains (losses) on net investment hedges Foreign currency translation adjustment(1) Recognized postretirement prior service cost: Reclassification of net (gains) losses from accumulated other comprehensive income (loss) Total other comprehensive income (loss) Year Ended December 31, 2016: Net unrealized gains (losses) on securities available for sale and interest-only strips: Unrealized gains (losses) arising during the period Reclassification of net (gains) losses from accumulated other comprehensive income (loss) Net unrealized gains (losses) Net unrealized gains (losses) on net investment hedges Foreign currency translation adjustment(1) Recognized postretirement prior service cost: Reclassification of net (gains) losses from accumulated other comprehensive income (loss) Total other comprehensive income (loss) Year Ended December 31, 2015: Net unrealized gains (losses) on securities available for sale and interest-only strips: Unrealized gains (losses) arising during the period Reclassification of net (gains) losses from accumulated other comprehensive $ $ $ $ income (loss) Net unrealized gains (losses) Net unrealized gains (losses) on net investment hedges Foreign currency translation adjustment(1) Recognized postretirement prior service cost: Reclassification of net (gains) losses from accumulated other comprehensive income (loss) Total other comprehensive income (loss) 208 24,452 (4,430) 4,921 (46) 859 (7,998) 1,684 — 17 24,897 $ (6,297) $ 1,067 16,454 (2,746) 4,921 (29) 18,600 (32,408) $ 12,323 $ (20,085) 1,913 (30,495) (1,213) 1,300 (46) (722) 11,601 457 — 17 1,191 (18,894) (756) 1,300 (29) (30,454) $ 12,075 $ (18,379) (2,523) $ 955 $ (1,568) 1,159 (1,364) 7,613 (8,304) (46) (407) 548 (2,900) — 17 $ (2,101) $ (2,335) $ 752 (816) 4,713 (8,304) (29) (4,436) (1)  Foreign investments are deemed to be permanent in nature and therefore TCF does not provide for taxes on foreign currency translation adjustments. Reclassifications of net (gains) losses to net income for securities available for sale and interest-only strips were recorded in the Consolidated Statements of Income in interest income for those securities that were previously transferred to held to maturity, in gains (losses) on securities, net for sales of securities and in other non-interest expense for interest-only strips. These reclassifications to net income are included in the table above in the line called Reclassification of net (gains) losses from accumulated other comprehensive income (loss). During 2014, TCF transferred $191.7 million of available for sale mortgage-backed securities to held to maturity. At December 31, 2017 and 2016, the unrealized holding loss on the transferred securities retained in accumulated other comprehensive income (loss) totaled $12.1 million and $13.0 million, respectively. These amounts are amortized over the remaining lives of the transferred securities. See Note 18. Employee Benefit Plans, for further information regarding TCF's recognized postretirement prior service cost. The tax effect of these reclassifications was recorded in income tax expense in the Consolidated Statements of Income. 119       The components of accumulated other comprehensive income (loss) were as follows: (In thousands) At or For the Year Ended December 31, 2017: Securities Available for Sale and Interest-only Strips Net Investment Hedges Foreign Currency Translation Adjustment Recognized Postretirement Prior Service Cost Total Balance, beginning of period $ (28,601) $ 6,493 $ (11,764) $ 147 $ Other comprehensive income (loss) Amounts reclassified from accumulated other comprehensive income (loss) Net other comprehensive income (loss) Adoption impact of ASU 2018-02 Balance, end of period At or For the Year Ended December 31, 2016: Balance, beginning of period Other comprehensive income (loss) Amounts reclassified from accumulated other comprehensive income (loss) Net other comprehensive income (loss) Balance, end of period At or For the Year Ended December 31, 2015: Balance, beginning of period Other comprehensive income (loss) Amounts reclassified from accumulated other comprehensive income (loss) Net other comprehensive income (loss) Balance, end of period $ $ $ $ $ 15,387 1,067 16,454 (4,206) (2,746) — (2,746) 789 4,921 — 4,921 — — (29) (29) 25 (16,353) $ 4,536 $ (6,843) $ 143 $ (9,707) $ 7,249 $ (13,064) $ 176 $ (20,085) 1,191 (18,894) (756) — (756) 1,300 — 1,300 — (29) (29) (28,601) $ 6,493 $ (11,764) $ 147 $ (8,891) $ 2,536 $ (4,760) $ 205 $ (1,568) 752 (816) 4,713 — 4,713 (8,304) — (8,304) — (29) (29) (9,707) $ 7,249 $ (13,064) $ 176 $ (33,725) 17,562 1,038 18,600 (3,392) (18,517) (15,346) (19,541) 1,162 (18,379) (33,725) (10,910) (5,159) 723 (4,436) (15,346) 120 Other Financial Data The selected quarterly financial data presented below should be read in conjunction with the Consolidated Financial Statements and related notes.

Changes in and Disagreements With Accountants on Accounting and Financial Disclosure None. Item 9A. 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 on that evaluation, management concluded that the Company's disclosure controls and procedures were effective as of December 31, 2017. Disclosure controls and procedures are designed to ensure that information required to be disclosed by TCF in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls are also designed with the objective of ensuring that such information is accumulated and communicated to the Company's management, including the Chief Executive Officer (Principal Executive Officer), Chief Financial Officer (Principal Financial Officer) and Chief Accounting Officer (Principal Accounting Officer), as appropriate, to allow for timely decisions regarding required disclosure. TCF's disclosure controls also include internal controls that are designed to provide reasonable assurance that transactions are properly authorized, assets are safeguarded against unauthorized or improper use and that transactions are properly recorded and reported. Changes in Internal Control Over Financial Reporting  There were no changes to TCF's internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the quarter ended December 31, 2017, that materially affected, or are reasonably likely to materially affect, TCF's internal control over financial reporting. 122     Management's Report on Internal Control Over Financial Reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting for TCF Financial Corporation (the "Company"). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company; provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles and that receipts and expenditures of the Company are only being made in accordance with authorizations of management and directors of the Company; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company's assets that could have a material effect on the financial statements. Management, with the participation of the Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), completed an assessment of TCF's internal control over financial reporting as of December 31, 2017. This assessment was based on criteria for evaluating internal control over financial reporting established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in May 2013. Based on this assessment, management concluded that TCF's internal control over financial reporting was effective as of December 31, 2017. KPMG LLP, the Company's independent registered public accounting firm that audited the consolidated financial statements included in this annual report, has issued an unqualified attestation report on the effectiveness of the Company's internal control over financial reporting as of December 31, 2017. Any control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. The design of a control system inherently has limitations and the benefits of controls must be weighed against their costs. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. Therefore, no assessment of a cost-effective system of internal controls can provide absolute assurance that all control issues and instances of fraud, if any, will be detected. 123 Report of Independent Registered Public Accounting Firm To the Stockholders and Board of Directors TCF Financial Corporation: Opinion on Internal Control Over Financial Reporting We have audited TCF Financial Corporation's and subsidiaries’ (the "Company") internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the consolidated statements of financial condition of the Company as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2017, and the related notes (collectively, the "consolidated financial statements"), and our report dated February 23, 2018 expressed an unqualified opinion on those consolidated financial statements. Basis for Opinion The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
