The sum of the budgets for all work packages, planning packages, etc, scheduled to be accomplished (including in-process work packages), plus the amount of level of effort and apportioned effort scheduled to be accomplished within a given time period. This is a special reporting set used in a number of standard reports and can change based on the terminology setting. By default in v4.x this set was titled BCWS. In v5.0, by default, is Budget. This cost set also appears as the cumulative to date budget in the Control Account pane of the Project View.
