Revenue Recognition and Operating Income - How does each firm recognize revenue and how does its revenue recognition policies compare to its competitors? Is there evidence of aggressive revenue recognition? Consider the firm's operating income and how it has been affected by "above the line" items including research and development expenses, restructuring costs, income taxes and foreign currency translation. Consider "below the line" components to income including discontinued operations and extraordinary items. Examine earnings per share and the impact of dilution from new shares (and potential new shares) and the anti-dilution effects of share buy-backs. Finally, consider the "quality of earnings" of your firms.
