Table of Contents The following table summarizes all probable environmental remediation, indemnification and restoration liabilities, including related legal expenses, at December 31, 2018 and 2017. These amounts include estimates for unasserted claims that the Company believes are probable of loss and reasonably estimable. The estimate of the range of reasonably possible costs is less certain than the estimates upon which the liabilities are based. To establish the upper end of a range, assumptions less favorable to the Company among the range of reasonably possible outcomes were used. As with any estimate, if facts or circumstances change, the final outcome could differ materially from these estimates. At both December 31, 2018 and 2017, $1 has been included in “Other current liabilities” in the Consolidated Balance Sheets with the remaining amount included in “Other long-term liabilities.” The Company is involved in various product liability, commercial and employment litigation, personal injury, property damage and other legal proceedings that are considered to be in the ordinary course of business. The Company has reserves of $1 at both December 31, 2018 and 2017 for all non- environmental legal defense costs incurred and settlement costs that it believes are probable and estimable. At December 31, 2018 and 2017, $1 has been included in “Other current liabilities” in the Consolidated Balance Sheets with less than $1 included in “Other long-term liabilities.” The Company has entered into contractual agreements with third parties for the supply of site services, utilities, materials and facilities and for operation and maintenance services necessary to operate certain of the Company’s facilities on a stand-alone basis. The duration of the contracts range from less than one year to 20 years, depending on the nature of services. These contracts may be terminated by either party under certain conditions as provided for in the respective agreements; generally, 90 days notice is required for short-term contracts and three years notice is required for longer-term contracts (generally those contracts in excess of five years). Contractual pricing generally includes a fixed and variable component. In addition, the Company has entered into contractual agreements with third parties to purchase feedstocks or other services. The terms of these agreements vary from one to ten years and may be extended at the Company’s request and are cancelable by either party as provided for in each agreement. Feedstock prices are based on market prices less negotiated volume discounts or cost input formulas. The Company is required to make minimum annual payments under these contracts as follows: Non-Environmental Legal Matters Other Commitments and Contingencies Purchase Commitments Year Minimum Annual Purchase Commitments 2019 $ 160 2020 47 2021 44 2022 35 2023 29 2024 and beyond 240 Total minimum payments 555 Less: Amount representing interest (71) Present value of minimum payments $ 484 Liability 2018 Range of Reasonably Possible Costs Site Description December 31, 2018 December 31, 2017 Low High Currently-owned $ 4 $ 3 $ 3 $ 9 Formerly-owned: Remediation — 1 — 2 Total $ 4 $ 4 $ 3 $ 11 154
