Operating Lease Commitments:    We lease certain real and personal property from unrelated third parties under non-cancelable operating leases. Future minimum lease payments under operating leases at October 31, 2017 were $42 million for 2018, $33 million for 2019, $19 million for 2020, $10 million for 2021, $6 million for 2022 and $26 million thereafter. Future minimum lease income under leases at October 31, 2017 was $9 million for 2018, $9 million for 2019, $8 million for 2020, and $10 million thereafter. Certain leases require us to pay property taxes, insurance and routine maintenance, and include escalation clauses. Total rent expense was $57 million in 2017, $61 million in 2016 and $65 million in 2015.

Contingencies: We are involved in lawsuits, claims, investigations and proceedings, including, but not limited to, patent, commercial and environmental matters, which arise in the ordinary course of business. There are no matters pending that we currently believe are reasonably possible of having a material impact to our business, consolidated financial condition, results of operations or cash flows.
