Certain intercompany sales within the Phosphates segment are recognized as revenue before the final price is determined.

There were no intersegment sales of this type outstanding at March 31, 2014. Profits on these Phosphates sales are eliminated in the "Corporate and Other" category similar to all other intercompany transactions.
