- DefinitionChange in Estimate - Contract Accounting: when adjustments in estimated total contract block revenue or estimated total cost are required, any changes from prior estimates for delivered units are recognized in the current period as a cumulative catch-up adjustment for the inception-to-date effect of such changes. Cumulative catch-up adjustments are driven by several factors including improved production efficiencies, assumed rate of production, the rate of overhead absorption, changes to scope of work and contract modifications. When estimates of total costs to be incurred on a contract block exceed estimates of total revenue to be earned, a provision for the entire loss on the contract block is recorded in the period in which the loss is determined.
