Organization And Formation	A. Partnership organization and formation Ferrellgas Partners, L.P. (“Ferrellgas Partners”) was formed on April 19, 1994, and is a publicly traded limited partnership, owning an approximate 99% limited partner interest in Ferrellgas, L.P. (the “operating partnership”). Ferrellgas Partners and the operating partnership, collectively referred to as “Ferrellgas,” are both Delaware limited partnerships and are governed by their respective partnership agreements. Ferrellgas Partners was formed to acquire and hold a limited partner interest in the operating partnership. As of July 31, 2020, Ferrell Companies Inc., a Kansas corporation (“Ferrell Companies”), beneficially owns 22.8 million of Ferrellgas Partners’ outstanding common units. Ferrellgas, Inc., a Delaware corporation and a wholly-owned subsidiary of Ferrell Companies, is the sole general partner of Ferrellgas Partners and one of three general partners of the operating partnership. Ferrellgas, Inc. has retained an approximate 1% general partner economic interest in Ferrellgas Partners and also holds an approximate 1% general partner economic interest in the operating partnership, representing an effective 2% general partner economic interest in Ferrellgas on a combined basis. As the sole general partner of Ferrellgas Partners, Ferrellgas, Inc. performs all management functions required by Ferrellgas Partners. Unless contractually provided for, creditors of the operating partnership have no recourse with regards to Ferrellgas Partners. On April 24, 2020, Ferrellgas Partners, the sole limited partner of the operating partnership, and Ferrellgas, Inc., the then-sole general partner of the operating partnership, amended and restated the partnership agreement of the operating partnership in order to, among other things, provide for the admission of two additional general partners. On April 27, 2020, Ferrellgas GP II, LLC and Ferrellgas GP III, LLC, each a Delaware limited liability company and a wholly-owned subsidiary of Ferrell Companies, were formed and subsequently admitted as additional general partners of the operating partnership. As the general partners of the operating partnership, Ferrellgas, Inc., Ferrellgas GP II, LLC and Ferrellgas GP III, LLC each have an equal vote and all general partner matters of the operating partnership are determined by the vote or consent of a majority of such entities. The general partners perform all management functions required by the operating partnership. The general partner interests held by Ferrellgas GP II, LLC and Ferrellgas GP III, LLC are strictly voting and non-economic. The term “general partner” (i) with respect to Ferrellgas Partners refers to Ferrellgas, Inc. and (ii) with respect to the operating partnership refers to (a) Ferrellgas, Inc., in the case of any economic general partner interest and (b) Ferrellgas, Inc., Ferrellgas GP II, LLC and Ferrellgas GP III, LLC, collectively, in the case of any voting general partner interest. Ferrellgas Partners is a holding entity that conducts no operations and has two subsidiaries, Ferrellgas Partners Finance Corp. and the operating partnership. Ferrellgas Partners owns a 100% equity interest in Ferrellgas Partners Finance Corp., whose only business activity is to act as the co-issuer and co-obligor of any debt issued by Ferrellgas Partners. The operating partnership is the only operating subsidiary of Ferrellgas Partners. Ferrellgas is primarily engaged in the retail distribution of propane and related equipment sales. The propane distribution market is seasonal because propane is used primarily for heating in residential and commercial buildings. Ferrellgas serves residential, industrial/commercial, portable tank exchange, agricultural, wholesale and other customers in all 50 states, the District of Columbia, and Puerto Rico. Going Concern The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the continuity of operations, the realization of assets and the satisfaction of liabilities in the normal course of business. Ferrellgas Partners has $357.0 million in unsecured notes due June 15, 2020, which Ferrellgas Partners failed to repay, that are classified as current in the consolidated financial statements. Additionally, Ferrellgas, L.P. has $500.0 million in unsecured notes due May 1, 2021, that are also classified as current in the consolidated financial statements. The ability of Ferrellgas Partners to restructure, refinance or otherwise satisfy these notes is uncertain considering the level of other outstanding indebtedness. Given these concerns, Ferrellgas Partners believes there is substantial doubt about the entity’s ability to continue as a going concern. Ferrellgas has engaged Moelis & Company LLC as its financial advisor and the law firm of Squire Patton Boggs LLP to assist in its ongoing process to reduce existing debt and address its debt maturities. The outcome of Ferrellgas’ debt reduction strategy continues to remain uncertain. Additionally, see Note I – Debt below for further discussion of the outstanding debt.
