Item 9A. CONTROLS AND PROCEDURES.

Disclosure Controls and Procedures

The Company's principal executive officer and its principal financial officer have concluded that the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the Exchange Act)) were effective as of October 28, 2018, based on the evaluation of these controls and procedures required by Rule 13a-15(b) or 15d-15(b) of the Exchange Act.

Management's Report on Internal Control Over Financial Reporting

The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting. The Company's internal control system was designed to provide reasonable assurance regarding the preparation and fair presentation of published financial statements in accordance with generally accepted accounting principles.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation in accordance with generally accepted accounting principles.

U.S. Securities and Exchange Commission guidance allows companies to exclude acquisitions from management's report on internal control over financial reporting for the first year after the acquisition when it is not possible to conduct an assessment. In December 2017, the Company acquired the stock and certain assets of substantially all of the business of Wirtgen Group Holding GmbH (Wirtgen) (see Note 4). Due to Wirtgen's global operations, management has excluded Wirtgen from the annual assessment of the effectiveness of internal control over financial reporting as of October 28, 2018. Wirtgen represents 9 percent of both the consolidated total assets and consolidated net sales and revenues of Deere & Company as of and for the year ended October 28, 2018.

Management assessed the effectiveness of the Company's internal control over financial reporting as of October 28, 2018, using the criteria set forth in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that assessment, management believes that, as of October 28, 2018, the Company's internal control over financial reporting was effective.

The Company's independent registered public accounting firm has issued an audit report on the effectiveness of the Company's internal control over financial reporting. That report is included herein.
