Basis of Consolidation and Presentation

Ingevity did not operate as a separate, stand-alone entity for the full three and six month periods ended June 30, 2016. Our Condensed Consolidated Statement of Operations and Comprehensive Income (Loss) for the three and six months ended June 30, 2016 as well as our Statements of Cash Flows for the six months ended June 30, 2016 have been prepared on a “carve out” basis for the periods and dates prior to the Separation on May 15, 2016.

Prior to the Separation, Ingevity's operations were included in WestRock's financial results and were comprised of certain WestRock wholly owned legal entities for which Ingevity was the sole business and components of legal entities in which Ingevity operated in conjunction with other WestRock businesses. For periods prior to May 15, 2016, the accompanying Condensed Consolidated Financial Statements were prepared from WestRock's historical accounting records and are presented on a stand-alone basis as if Ingevity's business operations had been conducted independently from WestRock. The Condensed Consolidated Financial Statements include the historical operations, assets and liabilities of the legal entities that comprised the Ingevity business.

In all periods presented within these Condensed Consolidated Financial Statements, all intercompany accounts and transactions have been eliminated. The Condensed Consolidated Financial Statements include the accounts of Ingevity and subsidiaries in which a controlling interest is maintained. If Ingevity's ownership is less than 100 percent, the outside stockholders' interests are shown as noncontrolling interests. In all periods presented, the noncontrolling interest reported within the Condensed Consolidated Financial Statements represents the 30 percent ownership interest held by a third party U.S.-based company in our consolidated Purification Cellutions LLC legal entity. Purification Cellutions LLC is the legal entity that owns the technology associated with, and manufactures, our structured honeycomb products within our Performance Materials segment.
