Explanations are often included on differences between each segment, such as 1) certain measurements of segment profit or loss (e.g. income before taxes, extraordinary items, discontinued operations, change in accounting principle) and assets and 2) changes in methods and measurements from prior year, between segment and consolidated assets.
