(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 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 that are 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, we believe there is substantial doubt about the entity’s ability to continue as a going concern. Ferrellgas has engaged Moelis & Company LLC as our financial advisor and the law firm of Squire Patton Boggs LLP to assist with the execution of our strategy to reduce our outstanding debt. The successful outcome of Ferrellgas’ debt reduction strategy continues to remain uncertain. Additionally, see Note H – Debt below for further discussion of the outstanding debt.
