Organization, Consolidation and Presentation of Financial Statements [Abstract]

New Accounting Pronouncements, Policy [Policy Text Block]

Standards Issued and Implemented

In the first quarter of 2019, we adopted Accounting Standards Update (ASU) 2016-02, Leases (Topic 842) and recognized on our Condensed Consolidated Statement of Financial Position $1,064 of lease liabilities with corresponding right-of-use assets for operating leases. Our accounting for finance leases and lessor contracts remains substantially unchanged. The standard has no impact to cash provided or used by operating, investing, or financing activities on our Condensed Consolidated Statements of Cash Flows. As permitted under the standard, we elected prospective application of the new guidance and prior periods continue to be presented in accordance with Topic 840. Refer to our 2018 Annual Report on Form 10-K for disclosures required by Topic 840. We also elected the package of practical expedients, which among other things, does not require reassessment of lease classification.

In the first quarter of 2019, we adopted ASU 2017-12, Derivatives and Hedging (Topic 815), using the modified retrospective method. The standard refines and simplifies hedge accounting requirements for both financial and commodity risks. The impact of the adoption was not material. See Note 17 for additional disclosures.

Lease policy [Policy Text Block]

Leases We determine if an arrangement is, or contains, a lease at the inception date. Operating leases are included in Other assets, with the related liabilities included in Accrued liabilities and Other long-term liabilities. Assets under finance leases are included in Property, plant and equipment, net, with the related liabilities included in Short-term debt and current portion of long-term debt and Long-term debt on the Condensed Consolidated Statements of Financial Position.

Operating lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. We use our estimated incremental borrowing rate in determining the present value of lease payments. Variable components of the lease payments such as fair market value adjustments, utilities, and maintenance costs are expensed as incurred and not included in determining the present value. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease term.

We have lease agreements with lease and non-lease components which are accounted for as a single lease component.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Changes in estimated revenues, cost of sales and the related effect on operating income are recognized using a cumulative catch-up adjustment which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a long-term contract’s percentage-of-completion. When the current estimates of total sales and costs for a long-term contract indicate a loss, a provision for the entire reach-forward loss on the long-term contract is recognized.

Net cumulative catch-up adjustments to prior years' revenue and earnings, including certain reach-forward losses, across all long-term contracts were as follows:

(In millions - except per share amounts)	Six months ended June 30					Three months ended June 30
	2019		2018			2019		2018
Increase/(decrease) to Revenue		$229		$45			$69		($72	)
Increase/(decrease) to Earnings from Operations		$175		($159	)		$28		($237	)
Increase/(decrease) to Diluted EPS		$0.22		($0.23	)		$0.04		($0.34	)

Earnings Per Share, Policy [Policy Text Block]

Basic and diluted earnings per share are computed using the two-class method, which is an earnings allocation method that determines earnings per share for common shares and participating securities. The undistributed earnings are allocated between common shares and participating securities as if all earnings had been distributed during the period. Participating securities and common shares have equal rights to undistributed earnings.

Basic earnings per share is calculated by taking net earnings, less earnings available to participating securities, divided by the basic weighted average common shares outstanding.

Diluted earnings per share is calculated by taking net earnings, less earnings available to participating securities, divided by the diluted weighted average common shares outstanding.

Backlog [Policy Text Block]

Our total backlog represents the estimated transaction prices on performance obligations to our customers for which work remains to be performed. Backlog is converted into revenue in future periods as work is performed, primarily based on the cost incurred or at delivery and acceptance of products, depending on the applicable accounting method.
