Employee Benefits	Employee benefits Ferrellgas has no employees and is managed and controlled by its general partner. Ferrellgas assumes all liabilities, which include specific liabilities related to the following employee benefit plans for the benefit of the officers and employees of the general partner. Ferrell Companies makes contributions to the ESOT, which causes a portion of the shares of Ferrell Companies owned by the ESOT to be allocated to employees’ accounts over time. The allocation of Ferrell Companies’ shares to employee accounts causes a non-cash compensation charge to be incurred by Ferrellgas, equivalent to the fair value of such shares allocated. This non-cash compensation charge is reported separately in Ferrellgas’ consolidated statements of operations and thus excluded from operating and general and administrative expenses. The non-cash compensation charges were $15.1 million, $27.6 million and $24.7 million during fiscal 2017, 2016 and 2015, respectively. Ferrellgas is not obligated to fund or make contributions to the ESOT. The general partner and its parent, Ferrell Companies, have a defined contribution profit-sharing plan which includes both profit sharing and matching contribution features. The plan covers substantially all full time employees. The plan, which qualifies under section 401(k) of the Internal Revenue Code, also provides for matching contributions under a cash or deferred arrangement based upon participant salaries and employee contributions to the plan. Matching contributions for fiscal 2017, 2016 and 2015 were $4.2 million, $4.0 million and $3.9 million, respectively. The general partner has a defined benefit plan that provides participants who were covered under a previously terminated plan with a guaranteed retirement benefit at least equal to the benefit they would have received under the terminated plan. Until July 31, 1999, benefits under the terminated plan were determined by years of credited service and salary levels. As of July 31, 1999, years of credited service and salary levels were frozen. The general partner’s funding policy for this plan is to contribute amounts deductible for Federal income tax purposes and invest the plan assets primarily in corporate stocks and bonds, U.S. Treasury bonds and short-term cash investments. During fiscal 2017, 2016 and 2015, other comprehensive income and other liabilities were adjusted by $0.5 million, $(0.3) million and $(0.2) million, respectively.
