^(a) Final price deferred is product that has shipped to customers, but the price has not yet been agreed upon. This has not been included in inventory as risk of loss has passed to our customers. Amounts in this account are based on inventory cost.

^(b) Included in restricted cash, as of September 30, 2015, is $630 million that is committed to be placed in trust following the effectiveness of the consent decrees discussed under "EPA RCRA Initiative" in Note 10 of our Notes to Condensed Consolidated Financial Statements, as financial assurance to support certain estimated future asset retirement obligations.
