[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, 2019 to June 30, 2020 reflected property additions, notably a capacity expansion project at our frozen dinner roll facility in Horse Cave, Kentucky, as well as operating lease right-of-use assets recorded in 2020 due to the adoption of new accounting guidance. 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.

[4] Restructuring and impairment charges 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, expenditures for Project Ascent 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.
