| Segment Reporting, CODM, Profit (Loss) Measure, How Used, Description | This assessment is primarily based on segment earnings from operations, as management believes this is the best metric for segment operating performance. The CODM uses operating earnings as part of his review of the monthly operating results on a segment basis. The actual monthly results are reviewed against budgeted amounts as well as the current-year reforecast and prior-year actual amounts. Interest and taxes are managed on a centralized basis and are not included in segment operating information. |
