Revenue from Contract with Customer [Text Block]

NOTE 4 - REVENUE

Substantially all of the Corporation's revenues are generated by intercompany sales to TDCC. Products are sold to and purchased from TDCC at market-based prices in accordance with the terms of TDCC’s intercompany pricing policies. Approximately 99 percent of the Corporation's revenue for the three and six months ended June 30, 2019, related to sales of product (99 percent for the three and six months ended June 30, 2018); the remaining 1 percent primarily related to the licensing of patents and technology. The Corporation sells its products to TDCC to simplify the customer interface process.

The Corporation’s contract liabilities include payments received in advance of performance under long-term contracts for product sales and royalties, and are realized when the associated revenue is recognized under the contract with remaining contract terms that range up to 22 years. The Corporation will have rights to future consideration for revenue recognized when product is delivered to the customer. The balance of contract liabilities was $40 million at June 30, 2019 ($41 million at December 31, 2018) and was included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the consolidated balance sheets.

The Corporation disaggregates its revenue from contracts with customers by type of customer (sales to related parties and sales to trade customers) as presented in the consolidated statements of income and believes this disaggregation best depicts the nature, amount, timing and uncertainty of its revenue and cash flows. Substantially all of the product sales are made to the parent entity, TDCC, and there are no unique economic factors that affect revenue recognition and cash flows associated with these product sales.
