CONSOLIDATED FINANCIAL STATEMENTS SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Jan. 01, 2019	Jan. 01, 2018
Accounting Policies [Abstract]
Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block]	Adoption of Accounting Standards 2019 In the first quarter of 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)," and associated ASUs (collectively, "Topic 842"). See Notes 2 and 14 for additional information. The Company added a significant accounting policy for leases as a result of the adoption of Topic 842: Leases The Company determines whether a contract contains a lease at contract inception. A contract contains a lease if there is an identified asset and the Company has the right to control the asset. Operating lease right-of-use (“ROU”) assets represent the Company's right to use an underlying asset for the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company uses the incremental borrowing rate (“IBR”) in determining the present value of lease payments, unless the implicit rate is readily determinable. If lease terms include options to extend or terminate the lease, the ROU asset and lease liability are measured based on the reasonably certain decision. Leases with a term of 12 months or less at the commencement date are not recognized on the balance sheet and are expensed as incurred. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for all classes of leased assets for which the Company is the lessee. Additionally, for certain equipment leases, the portfolio approach is applied to account for the operating lease ROU assets and lease liabilities. In the consolidated statements of income, lease expense for operating lease payments is recognized on a straight-line basis over the lease term. For finance leases, interest expense is recognized on the lease liability and the ROU asset is amortized over the lease term. Some leasing arrangements require variable payments that are dependent upon usage or output, or may vary for other reasons, such as insurance or tax payments. Variable lease payments are recognized as incurred and are not presented as part of the ROU asset or lease liability. Additionally, the Company's consolidated balance sheet reflects the impact of the adoption of ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)" and the associated ASUs (collectively, "Topic 606") at January 1, 2019, by certain nonconsolidated affiliates of the Company, which were subsequently distributed as part of the separation. The impact to the Company's investment was a reduction to "Investment in nonconsolidated affiliates" of $71 million and an increase to "Other noncurrent obligations" of $168 million, as well as an increase to "Deferred income tax assets" of $56 million and a reduction to "Retained earnings" of $183 million in the consolidated balance sheets at January 1, 2019.	2018 In the first quarter of 2018, the Company adopted Topic 606, ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities" and ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory." The adoption of these ASUs resulted in a net decrease of $68 million to retained earnings and a decrease of $20 million to accumulated other comprehensive loss ("AOCL") in the consolidated statements of equity at January 1, 2018. In the second quarter of 2018, the Company early adopted ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02")." The adoption of this standard resulted in a $1,057 million increase to retained earnings due to the reclassification from AOCL in the consolidated statements of equity at April 1, 2018.
