Receivables [Abstract]
Accounts Receivable Factoring and Other Receivables	Accounts Receivable Factoring and Other Receivables From time to time, we participate in factoring arrangements to sell accounts receivable to third-party financial institutions. In the first nine months of 2018, we sold accounts receivable of $284 million and recognized a loss of $2 million on these sales. We received cash proceeds totaling $278 million. In the first nine months of 2017, we sold accounts receivable of $150 million and recognized a loss of $1 million. Our factoring transactions in the first nine months of 2018 and 2017 were recognized as sales, and the proceeds are included as operating cash flows in our Condensed Consolidated Statements of Cash Flows. In the first quarter of 2017, we converted trade receivables of $65 million into a note from a customer with a face value of $65 million. The note had a three year term at a 4.625% stated interest rate. We reported the note as a trading security within “Other Current Assets” at fair value on the Condensed Consolidated Balance Sheets at its fair value of $58 million on March 31, 2017. The note fair value was considered a Level 2 valuation and was estimated using secondary market data for similar bonds. During the second quarter of 2017, we sold the note for $59 million.
