Cody uses a normal-costing system with two direct cost pools, labor and materials, and one indirect cost pool, general overhead. General overhead is allocated to each signing based on 80% of labor cost. Actual overhead equaled allocated overhead in March 2010. Actual overhead in April was $1,980. All costs incurred during the planning stage for a signing and during the signing are gathered in a balance sheet account called Signings in Progress (SIP). When a signing is completed, the costs are transferred to an income statement account called Cost of Completed Signings (CCS).
