New $575.0 million senior secured credit facility On May 4, 2018, the operating partnership entered into a new $575.0 million senior secured credit facility to replace its previous $575.0 million senior secured credit facility that was scheduled to mature in October 2018. This new facility consists of a $300.0 million revolving line of credit as well as a $275.0 million term loan, both priced at LIBOR + 5.75% and maturing May 4, 2023. The revolving line of credit includes a $125.0 million sublimit for the issuance of letters of credit. Borrowings under this facility are available for working capital needs, capital expenditures and other general partnership purposes, including the refinancing of existing indebtedness and acquisitions. At closing, the following transactions occurred: 1) the proceeds of the term loan were used to repay and terminate the operating partnership’s then existing credit facility, thus, no revolving credit loans were outstanding, 2) approximately $100 million of letters of credit were issued to replace the letters of credit under the operating partnership's then existing credit facility, and 3) the operating partnership held approximately $75 million of surplus cash. The term loan does not include any scheduled principal payments and the revolving credit facility does not have any scheduled commitment reductions before maturity; however, the credit facility requires prepayments pursuant to the following: 1) certain asset sales, 2) 50% of any excess cash flow, as defined in the credit agreement, in any fiscal year beginning with fiscal year 2019, 3) certain insurance proceeds, and 4) certain tax refunds. This new senior secured credit facility is secured with substantially all of the assets of the operating partnership and its subsidiaries, and Ferrellgas Partners’ and the general partner’s partnership interests in the operating partnership, and contains various affirmative and negative covenants and default provisions, as well as requirements with respect to the maintenance of specified financial ratios and limitations on the making of loans and investments. Amended accounts receivable securitization facility On May 14, 2018, the operating partnership entered into a seventh amendment to its accounts receivable securitization facility which extends the maturity date by three years, as well as increases the size of the facility from a maximum borrowing capacity of $225.0 million to $250.0 million at a discount rate of LIBOR plus 200 basis points. The amended accounts receivable securitization facility also includes provisions for the issuance of letters of credit with a $50.0 million sublimit. The facility continues to contain provisions where maximum purchase levels are reduced during periods of the year when working capital requirements are lower to efficiently reduce unused capacity fees.
