Subsequent Events	Note 25 - Subsequent Events As of August 31, 2018, a $550.0 million revolving line of credit, maturing October 2020, secured by substantially all the Company’s assets in the U.S. not otherwise pledged as security for term loans, was available to provide working capital and interim financing of equipment, principally for the U.S. and Mexican operations. Advances under this facility bear interest at LIBOR plus 1.75% or Prime plus 0.75% depending on the type of borrowing. Available borrowings under the credit facility are generally based on defined levels of inventory, receivables, property, plant and equipment and leased equipment, as well as total debt to consolidated capitalization and fixed charges coverage ratios. In September 2018, this revolving line of credit was renewed on terms similar to the existing facility and increased to $600.0 million with a new maturity date of September 2023. In addition, advances under this renewed facility bear interest at LIBOR plus 1.50% or Prime plus 0.50% depending on the type of borrowing. In September 2018, the Company refinanced approximately $170 million of existing senior term debt, due in March 2020, secured by a pool of leased railcars with new 5-year $225 million senior term debt also secured by a pool of leased railcars. The new debt bears a floating interest rate of LIBOR plus 1.50% or Prime plus 0.50%. The term loan is to be repaid in equal quarterly installments of $1.97 million with the remaining outstanding amounts, plus accrued interest, to be paid on the maturity date in September 2023. An interest rate swap agreement was entered into on 50% of the initial balance to swap the floating interest rate to a fixed rate of 2.99%. The Company intends to use hedge accounting to account for the interest rate swap agreement. In October 2018, the Company announced that Greenbrier and the Saudi Railway Company (SAR) signed an agreement to form a joint venture that will generate a total investment of 1 billion Saudi Riyals (USD $270 million) in the Saudi Arabia’s railway system and supply of freight railcars for the Saudi rail industry. The joint venture is subject to the completion of final due diligence by the parties and required government or corporate approvals.
