Basis of Presentation

On August 1, 2019 (the "Merger Date"), TCF Financial Corporation, a Delaware corporation ("Legacy TCF"), merged with and into Chemical Financial Corporation, a Michigan corporation ("Chemical"), with Chemical continuing as the surviving legal corporation (the "Merger"). Immediately following the Merger, Chemical’s wholly owned bank subsidiary, Chemical Bank, a Michigan state-chartered bank, merged with and into Legacy TCF’s wholly owned bank subsidiary, TCF National Bank, a national banking association, with TCF National Bank surviving the merger (“TCF Bank”). Upon completion of the Merger, Chemical was renamed TCF Financial Corporation. TCF Financial Corporation (together with its direct and indirect subsidiaries, "we," "us," "our," "TCF" or the "Corporation"), is a financial holding company, headquartered in Detroit, Michigan. TCF Bank has its main office in Sioux Falls, South Dakota. References herein to "TCF Financial" or the "Holding Company" refer to TCF Financial Corporation on an unconsolidated basis.

The Merger was accounted for as a reverse merger using the acquisition method of accounting, which means that for accounting and financial reporting purposes, Legacy TCF was deemed to have acquired Chemical in the Merger, even though Chemical was the legal acquirer. Accordingly, Legacy TCF's historical financial statements are the historical financial statements of the combined company for all periods before the Merger Date. TCF's results of operations for the third quarter of 2019 and the first nine months of 2019 include the results of operations of Chemical on and after August 1, 2019. Results for periods before August 1, 2019 reflect only those of Legacy TCF and do not include the results of operations of Chemical. The number of shares issued and outstanding, earnings per share, additional paid-in-capital, dividends paid and all references to share quantities of TCF have been retrospectively adjusted to reflect the equivalent number of shares issued to holders of Legacy TCF common stock in the Merger. See Note 2. Merger for further information. In addition, the assets and liabilities of Chemical as of the Merger Date have been recorded at their estimated fair value and added to those of Legacy TCF.

TCF Bank operates bank branches in Michigan, Minnesota, Illinois, Ohio, Indiana, Colorado, Wisconsin, Arizona and South Dakota (TCF's "primary banking markets"). Through its direct subsidiaries, TCF Bank provides a full range of consumer-facing and commercial services, including consumer and commercial banking, trust and wealth management, and specialty leasing and lending products and services to consumers, small businesses and commercial customers.

The accompanying unaudited consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles ("GAAP") for interim financial information and in accordance with the instructions to Quarterly Report on Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission ("SEC"). Accordingly, the consolidated financial statements do not include all of the information and notes necessary for complete financial statements in conformity with GAAP. In the opinion of management, the accompanying unaudited consolidated financial statements contain all the significant adjustments, consisting of normal recurring items, considered necessary for fair presentation. The results of operations for interim periods are not necessarily indicative of the results to be expected for the entire year. These interim unaudited financial statements should be read in connection with the Legacy TCF audited Consolidated Financial Statements and notes thereto, at and for the year ended December 31, 2018, which were filed as Exhibit 99.1 to TCF's Current Report on Form 8-K filed with the SEC on August 1, 2019, and together with Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Annual Report on Form 10-K of Legacy TCF for the year ended December 31, 2018.

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. Certain reclassifications have been made to prior period financial statements to conform to the current period presentation.

In connection with the Merger, effective August 1, 2019, TCF renamed its Wholesale Banking segment to Commercial Banking to align with the way TCF is now managed. In addition, activity that was related to small business banking and private banking were moved from the Wholesale Banking (now named Commercial Banking) segment to the Consumer Banking segment. The revised presentation of previously reported segment data has been applied retroactively for all periods presented in these financial statements. See Note 25. Reportable Segments for further information.
