On October 1, 2016, Trimble Navigation Limited changed its name to Trimble Inc. ("Trimble" or the "Company") and changed its state of incorporation from the State of California to the State of Delaware. Other than the change in corporate domicile, the reincorporation did not result in any change in the business, physical location, management, assets, liabilities or total stockholders' equity of the Company, nor did it result in any change in location of the Company's employees, including the Company's management. Trimble is a provider of technology solutions that enable professionals and field mobile workers to optimize or transform their work processes. Trimble's solutions are used across a range of industries including agriculture, architecture, civil engineering, survey and land administration, construction, geospatial, government, natural resources, transportation and utilities. Representative Trimble customers include engineering and construction firms, surveying companies, farmers and agricultural companies, transportation and logistics companies, energy and utility companies, and state, federal and municipal governments. Trimble focuses on integrating broad technological and application capabilities to create system-level solutions that transform how work is done within the industries the Company serves. Products are sold based on return on investment and provide benefits such as lower operational costs, higher productivity, improved quality, enhanced safety and regulatory compliance, and reduced environmental impact. Representative products include equipment that automates large industrial equipment such as tractors and bulldozers; integrated systems that track fleets of vehicles and workers and provide real-time information and powerful analytics to the back-office; data collection systems that enable the management of large amounts of geo-referenced information; software solutions that connect all aspects of a construction site or a farm; and building information modeling ("BIM") software that is used throughout the design, build, and operation of buildings. Basis of Presentation The Company has a 52-53 week fiscal year, ending on the Friday nearest to December 31, which for fiscal 2016 was December 30, 2016. The third quarter of fiscal 2017 and 2016 ended on September 29, 2017 and September 30, 2016, respectively. Both fiscal 2017 and 2016 are 52-week years. Unless otherwise stated, all dates refer to the Company’s fiscal year and fiscal periods. The Condensed Consolidated Financial Statements include the results of the Company and its consolidated subsidiaries. Inter-company accounts and transactions have been eliminated. Noncontrolling interests represent the noncontrolling stockholders’ proportionate share of the net assets and results of operations of the Company’s consolidated subsidiaries. Certain immaterial amounts from prior periods have been reclassified to conform to the current period presentation, including certain line items within the Consolidated Statement of Cash Flows, due to the adoption of accounting for certain aspects of the share-based payments awards, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements. Reportable Segments In March 2017, the Company effected a change in the reporting of its segment financial results to better reflect the Company's customer base and end markets. Beginning with the first quarter of fiscal 2017, the Company reports its financial performance, including revenues and operating income, based on four new reportable segments: Buildings and Infrastructure, Geospatial, Resources and Utilities, and Transportation. Comparative period financial information by reportable segment has been recast to conform with the current presentation.

Unaudited Interim Financial Information The accompanying financial data as of the end of the third quarter of fiscal 2017 and for the third quarter and the first three quarters of fiscal 2017 and 2016 have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements, prepared in accordance with U.S. generally accepted accounting principles, have been condensed or omitted pursuant to such rules and regulations. The Condensed Consolidated Balance Sheet as of fiscal year end 2016 is derived from the audited Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for fiscal year 2016. The following discussion should be read in conjunction with the Company’s 2016 Annual Report on Form 10-K. In the opinion of management, all adjustments necessary have been made to present a fair statement of financial position and results for the interim periods presented. The results of operations for the third quarter and the first three quarters of fiscal 2017 are not necessarily indicative of the operating results for the full fiscal year or any future periods. Individual segment revenue may be affected by seasonal buying patterns and general economic conditions. Use of Estimates The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in its Condensed Consolidated Financial Statements and accompanying notes. Estimates are used for allowances for doubtful accounts, sales returns reserve, allowances for inventory valuation, warranty costs, investments, goodwill impairment, intangibles impairment, purchased intangibles, stock-based compensation, and income taxes among others. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results may be different from the estimates. The Company has presented revenue and cost of sales separately for products, service, and subscriptions. Product revenue includes hardware, software licenses, parts and accessories; service revenue includes maintenance and support for hardware and software products, training, and professional services; subscription revenue includes software as a service ("SaaS").
