Financial Information for Reportable Segments
The measure of profit we use to make decisions on allocating resources to our operating segments and to assess the operating performance of each operating segment is operating income. Operating income is defined as income before interest expense, interest income, and income taxes. Corporate costs are allocated to each operating segment, and included in operating income, based on a rational and systematic basis.
Reportable segment assets presented below include those assets that are directly used in, or allocable to, that segments operations. Total assets for the Stores reportable segment primarily consist of merchandise inventory, the net book value of store facilities, and prepaid expenses and receivables related to store operations. Total assets for the Direct reportable segment primarily consist of merchandise inventory, the net book value of information technology and distribution center assets, and the net book value of goodwill and intangible assets as a result of the acquisition of Athleta. We do not allocate corporate assets to our operating segments. Unallocated corporate assets include cash and cash equivalents, restricted cash, the net book value of corporate property and equipment, and tax-related assets.
Selected financial information by reportable segment and reconciliations to our consolidated totals are as follows:
