Description of Business and Basis of Presentation	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Description of business Valvoline Inc. (“Valvoline” or the “Company”) is a leader in vehicle care delivering quick, easy, and trusted preventive maintenance services in its stores throughout the United States (“U.S.”) and Canada. The Company operates and franchises over 1,700 service center locations and is the second and third largest chain in the U.S. and Canada, respectively, by number of stores through its Valvoline Instant Oil Change and Great Canadian Oil Change retail locations. From cabin air filters to battery replacements to tire rotations, the Company’s stay-in-your-car service model offers a vast array of solutions for all types of vehicles. Established in 1866, Valvoline’s heritage spans more than 155 years, during which it has developed recognition across multiple channels. Valvoline's services performed at its retail stores using Valvoline-branded passenger car motor oils and complementary products are designed to serve evolving maintenance needs and improve vehicle and engine performance and lifespan. Strategic separation On July 31, 2022, the Company entered into a definitive agreement to sell its Global Products business to Aramco for a cash purchase price of $2.65 billion, subject to customary adjustments with respect to working capital and net indebtedness. The transaction is subject to standard closing conditions, including regulatory approvals and is expected to close in early calendar year 2023. Global Products sells engine and automotive products in more than 140 countries and territories to retailers, installers, and commercial customers to service light- and heavy-duty vehicles and equipment. In all periods presented within these consolidated financial statements, the assets and liabilities associated with the Global Products disposal group have been classified as held for sale within the Consolidated Balance Sheets and its operations have been classified as discontinued operations within the Consolidated Statements of Comprehensive Income and Cash Flows. Refer to Note 3 for additional information regarding the Global Products business, including the assets and liabilities held for sale and income from discontinued operations. Unless otherwise noted, disclosures within the remaining notes to these consolidated financial statements relate solely to the Company's continuing operations. As a result of classifying the former Global Products reportable segment as a discontinued operation, the Company has determined that it now operates a single reportable segment as the chief operating decision maker allocates resources and assesses performance on a consolidated basis for the continuing operations. Basis of presentation and consolidation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and Securities and Exchange Commission (“SEC”) regulations.
