Many commercial contracts include clauses based on cost accounting information and cost allocations. Examples include the following:
Contract disputes often arise over cost computations, for example, what costs should be included to calculate the costs specified in the contracts above. Managers can reduce disputes between contracting parties by explicitly writing the “rules of the game” into the contract. Such rules could include the definition of allowable cost items; the definitions of terms used, such as what constitutes direct labor; the permissible cost-allocation bases; and how to account for differences between budgeted and actual costs.
The U.S. government reimburses most contractors in one of two main ways:
Cost-plus contracts specify what costs are allowable. An allowable cost is a cost that the contract parties agree to include in the costs to be reimbursed. For example, only economy-class airfares are allowable in many U.S. government contracts. Contracts also identify cost categories that are unallowable. For example, the costs of lobbying activities and alcoholic beverages are not allowable costs in U.S. government contracts. However, the set of allowable costs is not always clear-cut. Contract disputes and allegations about overcharging the government arise from time to time across a range of areas including health care (see Concepts in Action: Contract Disputes Over Reimbursable Costs With the U.S. Government).
Some allowable overhead costs, such as supervision costs, support many different contracts and activities. Government regulations stipulate that supervision costs would be allocable to a specific contract on a cause-and-effect or benefits received basis. Other allowable overhead costs, such as general administration costs, support many contracts and are difficult to allocate based on cause-and-effect or benefits received. Nonetheless, the contracting parties may still view it as “reasonable” or “fair” to allocate these costs in some manner to help establish a contract amount. The general rule for government cost-plus contracts is that the reimbursement amount is based on actual allocable costs plus a fixed fee.*
All contracts with U.S. government agencies must comply with cost accounting standards issued by the Cost Accounting Standards Board (CASB). For government contracts, the CASB has the exclusive authority to make, put into effect, amend, and rescind cost accounting standards and interpretations. The standards are designed to achieve uniformity and consistency in the measurement, assignment, and allocation of costs to government contracts within the United States.* The standards represent the complex interplay of political considerations and accounting principles. Terms such as fairness and equity, as well as cause and effect and benefits received, are relevant to and a part of government contracts.
