Description of Business and Basis of Presentation	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Description of Business The Hain Celestial Group, Inc., a Delaware corporation, and its subsidiaries (collectively, the “Company,” and herein referred to as “Hain Celestial,” “we,” “us,” and “our”) was founded in 1993 and is headquartered in Lake Success, New York. The Company’s mission has continued to evolve since its founding, with health and wellness being the core tenet — To Create and Inspire A Healthier Way of Life^TMand be the leading marketer, manufacturer and seller of organic and natural, “better-for-you” products by anticipating and exceeding consumer expectations in providing quality, innovation, value and convenience. The Company is committed to growing sustainably while continuing to implement environmentally sound business practices and manufacturing processes. Hain Celestial sells its products through specialty and natural food distributors, supermarkets, natural food stores, mass-market and e-commerce retailers, food service channels and club, drug and convenience stores in over 80 countries worldwide. The Company manufactures, markets, distributes and sells organic and natural products under brand names that are sold as “better-for-you” products, providing consumers with the opportunity to lead A Healthier Way of Life™. Hain Celestial is a leader in many organic and natural products categories, with many recognized brands in the various market categories it serves, including Almond Dream^®, Arrowhead Mills^®, Bearitos^®, Better Bean^®, BluePrint^®, Casbah^®, Celestial Seasonings^®, Clarks™, Coconut Dream^®, Cully & Sully^®, Danival^®, DeBoles^®, Earth’s Best^®, Ella’s Kitchen^®, Empire^®, Europe’s Best^®, Farmhouse Fare^™, Frank Cooper’s^®, FreeBird^®, Gale’s^®, Garden of Eatin’^®, GG UniqueFiber^TM, Hain Pure Foods^®, Hartley’s^®, Health Valley^®, Imagine^®, Johnson’s Juice Co.^®, Joya^®, Kosher Valley^®, Lima^®, Linda McCartney’s^® (under license), MaraNatha^®, Mary Berry (under license), Natumi^®, New Covent Garden Soup Co.^®, Orchard House^®, Plainville Farms^®, Rice Dream^®, Robertson’s^®, Rudi’s Gluten-Free Bakery^®, Rudi’s Organic Bakery^®, Sensible Portions^®, Spectrum Organics^®, Soy Dream^®, Sun-Pat^®, Sunripe^®, SunSpire^®, Terra^®, The Greek Gods^®, Tilda^®, Walnut Acres^®, WestSoy^®, Yorkshire Provender^®, Yves Veggie Cuisine^®and William’s™. The Company’s personal care products are marketed under the Alba Botanica^®, Avalon Organics^®, Earth’s Best^®, JASON^®, Live Clean^® and Queen Helene^® brands. During fiscal year 2016, the Company commenced a strategic review, called “Project Terra,” that resulted in the Company redefining its core platforms, starting with the United States segment, for future growth based upon consumer trends to create and inspire A Healthier Way of Life™. In addition, beginning in fiscal year 2017, the Company launched Cultivate Ventures (“Cultivate”), a venture unit with a twofold purpose: (i) to strategically invest in the Company’s smaller brands in high potential categories such as BluePrint^® cold-pressed juices, SunSpire^® chocolates and DeBoles^® pasta by giving those products a dedicated, creative focus for refresh and relaunch; and (ii) to incubate small acquisitions until they reach the scale for the Company’s core platforms. See Note 19, Segment Information, for information on the Company’s operating and reportable segments and the effect the formation of Cultivate had thereon. Another key initiative from Project Terra was the identification of global cost savings, as well as removing complexities from the business. Under this plan, the Company aims to achieve $350 million in global savings by fiscal 2020, a portion of which the Company intends to reinvest into its brands. This review includes streamlining the Company’s manufacturing plants, co-packers and supply chain, eliminating served categories or brands within categories and product rationalization initiatives which are aimed at eliminating slow moving stock-keeping units (“SKUs”). During fiscal 2018, the Company initiated a SKU rationalization, which included the removal of over 400 SKUs for a total of over 1,100 SKUs to date identified as part of Project Terra. Additionally, the Company, with the assistance of outside consultants, engaged in an evaluation of its trade investment in the United States segment. Based on this assessment, the Company determined that its trade investment could be utilized more effectively, and therefore, beginning in fiscal 2017, the Company developed plans to shift from a model of investing in trade at the non-consumer facing level to more consumer facing activities. Discontinued Operations In March 2018, the Company’s Board of Directors approved a plan to sell all of the operations of the Hain Pure Protein Corporation (“HPPC”) and EK Holdings, Inc. (“Empire”) operating segments, which are reported in the aggregate as the Hain Pure Protein reportable segment. These dispositions are being undertaken to reduce complexity in the Company’s operations and simplify the Company’s brand portfolio, in addition to allowing additional flexibility to focus on opportunities for growth and innovation in the Company’s more profitable and faster growing core businesses. Collectively, these dispositions represent a strategic shift that will have a major impact on the Company’s operations and financial results and have been accounted for as discontinued operations. See Note 5, Discontinued Operations, for additional information. Changes in Segments Effective July 1, 2017, due to changes to the Company’s internal management and reporting structure, the United Kingdom operations of the Ella’s Kitchen^® brand (“Ella’s Kitchen UK”), which was previously included within the United States reportable segment, became a separate operating segment and was aggregated within the United Kingdom reportable segment. See Note 19, Segment Information, for additional information on the Company’s operating and reportable segments. Basis of Presentation The Company’s consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. Investments in affiliated companies in which the Company exercises significant influence, but which it does not control, are accounted for under the equity method of accounting. As such, consolidated net income includes the Company’s equity in the current earnings or losses of such companies. Unless otherwise indicated, references in these consolidated financial statements to 2018, 2017 and 2016 or “fiscal” 2018, 2017 and 2016 or other years refer to our fiscal year ended June 30 of that respective year and references to 2019 or “fiscal” 2019 refer to our fiscal year ending June 30, 2019. Reclassifications Certain prior year amounts have been reclassified to conform with current year presentation. Discontinued Operations The financial statements separately report discontinued operations and the results of continuing operations (See Note 5). All footnotes exclude discontinued operations unless otherwise noted. Use of Estimates The financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The accounting principles we use require us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and amounts of income and expenses during the reporting periods presented. These estimates include, among others, revenue recognition, trade promotions and sales incentives, valuation of accounts and chargeback receivables, accounting for acquisitions, valuation of long-lived assets, goodwill and intangible assets, stock-based compensation, and valuation allowances for deferred tax assets. We believe in the quality and reasonableness of our critical accounting estimates; however, materially different amounts may be reported under different conditions or using assumptions different from those that we have consistently applied.
