Leases and Commitments

12 Months Ended

Dec. 31, 2017

We have entered into operating leases for certain facilities, automobiles and equipment. The future minimum obligations under operating leases having a noncancelable term in excess of one year are as follows:



	Year Ending December 31
2018	$	170
2019	130
2020	99
2021	65
2022	48
Thereafter	98
Future minimum obligations	$	610

Consolidated rental expense under operating leases was $281, $271 and $279 in 2017, 2016 and 2015, respectively.

We have entered into long-term contracts for the purchase of superabsorbent materials, pulp and certain utilities. Commitments under these contracts based on current prices are $699 in 2018, $206 in 2019, $204 in 2020, $8 in 2021, $5 in 2022, and $51 beyond the year 2022.

Although we are primarily liable for payments on the above-mentioned leases and purchase commitments, our exposure to losses, if any, under these arrangements is not material.
