Segment Disclosures

29.   Segment Disclosures

        We are organized and managed based on two segments, which are differentiated primarily by their products, the markets they serve and the regulatory environments in which they operate. The two segments are the nitrogen segment and the phosphate segment. The Company's management uses gross margin to evaluate segment performance and allocate resources. Selling, general and administrative expenses, other operating—net, non-operating—net, interest, and income taxes, are centrally managed and not included in the measurement of segment profitability reviewed by management. The accounting policies of the segments are the same as those described in Note 2—Summary of Significant Accounting Policies.

        Segment data for net sales, cost of sales, gross margin, depreciation, depletion and amortization, capital expenditures, and assets for 2013, 2012 and 2011 are shown in the following tables. Other assets, capital expenditures and depreciation include amounts attributable to the corporate headquarters and unallocated corporate assets, such as our cash and cash equivalents, equity method investments and other investments.
