______________________________

(a) Final price deferred is product that has shipped to customers, but the price has not yet been agreed upon.

(b) We adopted ASC 842 effective January 1, 2019, with an immaterial, cumulative-effect adjustment to the opening balance of retained earnings as of that date. As allowed under the standard, we have not changed our accounting and reporting for lease arrangements for periods presented prior to January 1, 2019. See Note 4 to the Consolidated Financial Statements for additional information on the impact to our Consolidated Balance Sheets.

(c)

The timing of recognition of revenue related to our performance obligations may be different than the timing of collection of cash related to those performance obligations.  Specifically, we collect prepayments from certain customers in Brazil. In addition, cash collection from Canpotex may occur prior to delivery of product to the end customer.  We generally satisfy our contractual liabilities within one quarter of incurring the liability.
