Basis of Presentation	BASIS OF PRESENTATION Valvoline Inc. (“Valvoline” or the “Company”) is a subsidiary of Ashland Global Holdings Inc. (which together with its predecessors and consolidated subsidiaries is referred to as “Ashland” or “Parent”). On September 22, 2015, Ashland announced that its Board of Directors approved proceeding with a plan to separate Ashland into two independent, publicly traded companies comprising of the Valvoline business and the specialty chemicals businesses (the “Separation”). Following a series of restructuring steps, Valvoline was incorporated in May 2016, and prior to the completion of the Company’s initial public offering (“IPO”) on September 28, 2016, substantially all of the historical Valvoline business reported by Ashland, as well as certain other legacy Ashland assets and liabilities, were transferred to Valvoline. After completing the IPO, Ashland owns approximately 83% of the total outstanding shares of Valvoline’s common stock. Subject to market conditions and other factors, Ashland presently intends to distribute the remaining Valvoline shares in 2017 following the release of March-quarter earnings results by both Ashland and Valvoline. The contribution of the Valvoline business by Ashland to Valvoline was treated as a reorganization of entities under common Ashland control. As a result, Valvoline is retrospectively presenting the condensed consolidated financial statements of Valvoline and its subsidiaries for periods presented prior to the completion of the IPO, which have been prepared a stand-alone basis and derived from Ashland’s consolidated financial statements and accounting records using the historical results of operations, and assets and liabilities attributed to Valvoline’s operations, and includes allocations of expenses from Ashland. The condensed consolidated financial statements for periods presented subsequent to the completion of the IPO reflect the consolidated operations of Valvoline and its majority-owned subsidiaries as a separate, stand-alone entity. For periods prior to the completion of the IPO, transactions between Valvoline and Ashland were considered to be effectively settled for cash at the time the transactions were recorded. These transactions and net cash transfers to and from Ashland’s centralized cash management system are reflected as a component of Parent company investment on the Condensed Consolidated Balance Sheets and as a financing activity within the accompanying Condensed Consolidated Statements of Cash Flows.

BASIS OF PRESENTATION

Valvoline Inc. (“Valvoline” or the “Company”) is a subsidiary of Ashland Global Holdings Inc. (which together with its predecessors and consolidated subsidiaries is referred to as “Ashland” or “Parent”). On September 22, 2015, Ashland announced that its Board of Directors approved proceeding with a plan to separate Ashland into two independent, publicly traded companies comprising of the Valvoline business and the specialty chemicals businesses (the “Separation”). Following a series of restructuring steps, Valvoline was incorporated in May 2016, and prior to the completion of the Company’s initial public offering (“IPO”) on September 28, 2016, substantially all of the historical Valvoline business reported by Ashland, as well as certain other legacy Ashland assets and liabilities, were transferred to Valvoline. After completing the IPO, Ashland owns approximately 83% of the total outstanding shares of Valvoline’s common stock. Subject to market conditions and other factors, Ashland presently intends to distribute the remaining Valvoline shares in 2017 following the release of March-quarter earnings results by both Ashland and Valvoline.

The contribution of the Valvoline business by Ashland to Valvoline was treated as a reorganization of entities under common Ashland control. As a result, Valvoline is retrospectively presenting the condensed consolidated financial statements of Valvoline and its subsidiaries for periods presented prior to the completion of the IPO, which have been prepared a stand-alone basis and derived from Ashland’s consolidated financial statements and accounting records using the historical results of operations, and assets and liabilities attributed to Valvoline’s operations, and includes allocations of expenses from Ashland. The condensed consolidated financial statements for periods presented subsequent to the completion of the IPO reflect the consolidated operations of Valvoline and its majority-owned subsidiaries as a separate, stand-alone entity.

For periods prior to the completion of the IPO, transactions between Valvoline and Ashland were considered to be effectively settled for cash at the time the transactions were recorded. These transactions and net cash transfers to and from Ashland’s centralized cash management system are reflected as a component of Parent company investment on the Condensed Consolidated Balance Sheets and as a financing activity within the accompanying Condensed Consolidated Statements of Cash Flows. The Parent company investment on the Condensed Consolidated Balance Sheets represents the cumulative net investment by Ashland in Valvoline, including net income through the completion of the IPO and net cash transfers to and from Ashland.

A detailed listing of all new accounting standards relevant to Valvoline is included in the Annual Report on Form 10-K for the fiscal year ended September 30, 2016. The following standard relevant to Valvoline was adopted in the current period.

In April 2015, the FASB issued accounting guidance to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement.
