[1] All intercompany transactions have been eliminated.

[2] Net sales and long-lived assets are predominately domestic.

[3] Retail and Foodservice identifiable assets include those assets used in our operations and other intangible assets allocated to purchased businesses. Corporate assets consist principally of cash and equivalents. The increase in Retail and Foodservice identifiable assets from June 30, 2018 to June 30, 2019 was due to the acquisitions of Bantam and Omni. The increase in Corporate identifiable assets from June 30, 2017 to June 30, 2018 was primarily due to the increase in cash and equivalents.

[4] Restructuring and impairment charges and multiemployer pension settlement and related costs were not allocated to our two reportable segments due to their unusual nature.

[5] As discussed above, we do not present identifiable assets, payments for property additions or depreciation and amortization by reportable segment.

[6] Our Corporate Expenses include various expenses of a general corporate nature, ERP expenses and costs related to certain divested or closed nonfood operations. By their very nature, these costs have not been allocated to the Retail and Foodservice segments.
