Note 1. Organization, Operations and Basis of Presentation

Business Description

Resideo Technologies, Inc. (“Resideo” or “the Company”), is a leading global manufacturer and developer of technology-driven products that provide critical comfort, residential thermal and security solutions to homes globally. The Company is also the leading wholesale distributor of low-voltage security products including intrusion, access control and video products, and participates significantly in the broader related markets of smart home, fire, power, audio, ProAV, networking, communications, wire and cable, and data communications. The Company has a global footprint serving commercial and residential end markets.

The Company was incorporated in Delaware on April 24, 2018. The Company separated from Honeywell International Inc. (“Honeywell”) on October 29, 2018, becoming an independent publicly traded company as a result of a pro rata distribution of the Company’s common stock to shareholders of Honeywell (the “Spin-Off”).

Basis of Presentation

The Company’s financial statements are presented on a consolidated basis (collectively, the “Interim Financial Statements”) and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). All intercompany transactions have been eliminated for all periods presented. The Interim Financial Statements are unaudited; however, in the opinion of management, they contain all the adjustments (consisting of those of a normal recurring nature) considered necessary to state fairly the financial position, results of operations and cash flows for the periods presented in conformity with U.S. GAAP applicable to interim periods.

The Company reports financial information on a fiscal quarter basis using a “modified” 4-4-5 calendar (modified in that the fiscal year always begins on January 1 and ends on December 31) that requires its businesses to close their first, second and third quarter books on a Saturday in order to minimize the potentially disruptive effects of quarterly closing on business processes. The effects of this practice are generally not significant to reported results for any quarter and only exist within a reporting year. In the event that differences in closing dates are material to year-over-year comparisons of quarterly or year-to-date results, the Company will provide appropriate disclosures.

Reclassification

The prior year segment information was recast to present Corporate separately. See Note 4. Segment Financial Data for additional information. Certain reclassifications have been made to the prior period financial statements to conform to the classification adopted in the current period.
