Contract costs include all direct costs, such as materials and labor, and those indirect costs related to contract performance such as payroll taxes and insurance. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability may result in revisions to costs and income and are recognized in the period in which the revisions are determined. An amount equal to contract costs attributable to claims is included in revenues when realization is probable and the amount can be reliably estimated.
