The following tables present additions to property and intangibles, depreciation and amortization and total assets by reportable segment. Additions to property and intangibles exclude any additions through business acquisitions (see Note 4). Due to the level of integration between the Foodservice and Refrigerated Retail segments, it is impracticable to present additions to property and intangibles and total assets separately for each segment. As such, an allocation has been made between the two segments for depreciation based on inventory costing.
