Costpoint calculates ITD revenue to recognize by multiplying the percent complete from the Manage Revenue Information screen by the total contract value on the Manage Modifications screen. This value is the total ITD revenue to recognize. The program sums the revenue in the project ledger for the fiscal year up to and including the subperiod being calculated. This value becomes YTD revenue recognized previously. Revenue from the prior year table for fiscal years earlier than the selected fiscal year is summarized. Costpoint adds this value to the YTD revenue previously recognized to arrive at ITD revenue previously recognized. It then subtracts this amount from the ITD revenue to recognize to arrive at revenue not yet recognized. This amount can be positive or negative. If ITD revenue exceeds the total project ceiling, the amount over the ceiling is posted as an over the ceiling amount to the owning organization in the subperiod being calculated. This reduces revenue to the ceiling amount.
