Operating leases

Initial terms for leased premises in the U.S. are typically 15 to 25 years, followed by additional terms containing renewal options at five-year intervals, and may include rent escalation clauses. Non-U.S. leases are typically for shorter terms and may include cancellation clauses or renewal options. The commencement date of all lease terms is the earlier of the date the Company becomes legally obligated to make rent payments or the date the Company has the right to control the property. The Company recognizes rent expense on a straight-line basis over the term of the lease. In addition to minimum fixed rentals, some leases provide for contingent rentals based upon a portion of sales.

The Company continuously evaluates its real estate portfolio in conjunction with its capital needs. Historically, the Company has entered into several sale-leaseback transactions. For the six months ended February 28, 2018, the Company did not record any proceeds from sale-leaseback transactions. For the six months ended February 28, 2017, the Company recorded proceeds from sale-leaseback transactions of $436 million.

The Company provides for future costs related to closed locations. The liability is based on the present value of future rent obligations and other related costs (net of estimated sublease rent) to the first lease option date. During the three and six months ended February 28, 2018, the Company recorded charges of $28 million and $67 million for facilities that were closed. This compares to $247 million and $264 million for the three and six months ended February 28, 2017. These charges are reported in selling, general and administrative expenses in the Consolidated Condensed Statements of Earnings.

The changes in reserve for facility closings and related lease termination charges primarily in other non-current liabilities, include the following (in millions):
