[1] Equity in pretax earnings 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] Restructuring and impairment costs are excluded from segment operating income, but are included in consolidated operating income in the consolidated statements of income and comprehensive income.

[3] Other income represents a gain from remeasuring to fair value the Company's original 50% ownership interest in Procesadora Unitab, S.A., a tobacco processing joint venture in Guatemala, upon acquiring the 50% interest held by the Company's joint venture partner. This item is excluded from segment operating income, but is included in consolidated operating income in the consolidated statements of income and comprehensive income.

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

[5] 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 its financial results consist principally of equity in the pretax earnings of an unconsolidated affiliate.
