[1] Equity in pretax earnings (loss) of unconsolidated affiliates is included in segment operating income (Other Tobacco Operations segment), but is reported below consolidated operating income and excluded from that total in the consolidated statements of income and comprehensive income

[2] Includes South America, Africa, Europe, and Asia regions, as well as inter-region eliminations.

[3] Includes Dark Air-Cured, Special Services, and Oriental, as well as inter-company eliminations. Sales and other operating revenues for this reportable segment include limited amounts for Oriental because the business is accounted for on the equity method and its financial results consist principally of equity in the pretax earnings (loss) of unconsolidated affiliates.
