Production cost control was evaluated with the production work order performance report. Actual costs incurred- including direct materials use and manufacturing resource consumption-were compare with the authorized cost which equaled the current standard product cost per unit multiplied by the actual quantity produced. Price (materials, cost rate) and performance (materials usage, manufacturing efficiency, and alternative routing) variances were separately identified. Absorption of product cost into inventory was accomplished using current standard product cost rates so that all production cost variances were expensed as period cost. In addition, management accounting cost procedures-such as straight-line depreciation base on replacement costs-which were not allowable for financial (external) accounting purpose were offset in a reconciliation routine when preparing the semi-annual financial reports.
