Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business	BUSINESS The Hain Celestial Group, Inc., a Delaware corporation (collectively, along with its subsidiaries, 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^TM and 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 70 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^®, Bearitos^®, Better Bean^®, BluePrint^®, Celestial Seasonings^®, Clarks™, Coconut Dream^®, Cully & Sully^®, Danival^®, DeBoles^®, Earth’s Best^®, Ella’s Kitchen^®, Farmhouse Fare™, Frank Cooper’s^®, Gale’s^®, Garden of Eatin’^®, GG UniqueFiber^®, Hain Pure Foods^®, Hartley’s^®, Health Valley^®, Imagine^®, Johnson’s Juice Co.™, Joya^®, Lima^®, Linda McCartney^® (under license), MaraNatha^®, Mary Berry (under license), Natumi^®, New Covent Garden Soup Co.^®, Orchard House^®, Rice Dream^®, Robertson’s^®, Sensible Portions^®, Spectrum^®Organics, Soy Dream^®, Sun-Pat^®, Sunripe^®, Terra^®, The Greek Gods^®, Walnut Acres^®, 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. The Company’s strategy is to focus on simplifying the Company’s portfolio and reinvigorating profitable sales growth through discontinuing uneconomic investment, realigning resources to coincide with individual brand roles, reducing unproductive stock-keeping units (“SKUs”) and brands, and reassessing current pricing architecture. As part of this initiative, the Company reviewed its product portfolio within North America and divided it into “Get Bigger” and “Get Better” brand categories. The Company’s “Get Bigger” brands represent its strongest brands with higher margins, which compete in categories with strong growth. In order to capitalize on the potential of these brands, the Company began reallocating resources to optimize assortment and increase share of distribution. In addition, the Company will increase its marketing and innovation investments. The Company’s “Get Better” brands are the brands in which the Company is primarily focused on simplification and expansion of profit. Some of these are low margin, non-strategic brands that add complexity with minimal benefit to the Company’s operations. Accordingly, in fiscal 2019, the Company initiated a SKU rationalization, which included the elimination of approximately 350 low velocity SKUs. The elimination of these SKUs is expected to impact sales growth in the current fiscal year, but is expected to result in expanded profits and a remaining set of core SKUs that will maintain their shelf space in the store. As part of the Company’s overall strategy, the Company may seek to dispose of businesses and brands that are less profitable or are otherwise less of a strategic fit within our core portfolio. Accordingly, the Company divested of all of its operations of the Hain Pure Protein reportable segment and WestSoy® tofu, seitan and tempeh businesses in the United States in fiscal 2019, the entities comprising its Tilda operating segment and certain other assets of the Tilda business in August 2019, its Arrowhead Mills® and SunSpire® brands in October 2019, and its Europe's Best® and Casbah® brands in March 2020. Productivity and Transformation Costs As part of the Company’s historical strategic review, it focused on a productivity initiative, which it called “Project Terra.” A key component of this project was the identification of global cost savings and the removal of complexity from the business. In fiscal 2019, the Company announced a new transformation initiative, of which one aspect is to identify additional areas of productivity savings to support sustainable profitable performance. Productivity and transformation costs include costs, such as consulting and severance costs, relating to streamlining the Company’s manufacturing plants, co-packers and supply chain, eliminating served categories or brands within those categories, and product rationalization initiatives which are aimed at eliminating slow moving SKUs. Discontinued Operations On August 27, 2019, the Company and Ebro Foods S.A. (the “Purchaser”) entered into, and consummated the transactions contemplated by, an agreement titled, "Agreement relating to the sale and purchase of the Tilda Group Entities and certain other assets" (the “Sale and Purchase Agreement”). On February 15, 2019, the Company completed the sale of substantially all of the assets used primarily for the Plainville Farms business, a component of the Company’s Hain Pure Protein Corporation (“HPPC”) operating segment. On June 28, 2019, the Company completed the sale of the remainder of HPPC and Empire Kosher which included the FreeBird and Empire Kosher businesses. These dispositions were 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 were reported in the aggregate as the Hain Pure Protein reportable segment. These dispositions represented strategic shifts that had a major impact on the Company’s operations and financial results and therefore, the Company is presenting the operating results and cash flows of the Tilda operating segment and the Hain Pure Protein reportable segment within discontinued operations in the current and prior periods. The assets and liabilities of the Tilda operating segment are presented as assets and liabilities of discontinued operations in the Consolidated Balance Sheet as of June 30, 2019. See Note 5, Discontinued Operations, for additional information. Change in Reportable Segments Historically, the Company had three reportable segments: United States, United Kingdom and Rest of World. Effective July 1, 2019, the Company reassessed its segment reporting structure and as a result, the Canada and Hain Ventures operating segments, which were included within the Rest of World reportable segment, were moved to the United States reportable segment and renamed the North America reportable segment. Additionally, the Europe operating segment, which was included in the Rest of World reportable segment, was combined with the United Kingdom reportable segment and renamed the International reportable segment. Accordingly, the Company now operates under two reportable segments: North America and International. Prior period segment information contained herein has been adjusted to reflect the Company’s new operating and reporting structure. See Note 17, Segment Information, for additional information.
