| Segment Reporting, CODM, Profit (Loss) Measure, How Used, Description | The CODM uses forecast-to-actual variances and year-over-year variances on a monthly basis when assessing segment performance and forecasts in deciding how to allocate resources among the segments. The CODM evaluates the performance of the Company’s segments based on reportable segment operating profit. In connection with that assessment, Woodward generally excludes matters such as certain charges for restructuring, interest income and expense, certain gains and losses from asset dispositions, or other unusual and/or non-operationally related expenses. |
