CAS 411 provides criteria for accounting for the measurement and assignment of material costs to cost objectives and follows generally accepted accounting principles (GAAP).
What is the Purpose of CAS 411?
If you don’t have contracts subject to full CAS, then FAR 31.205-26 Material costs requires contractors to implement GAAP when accounting for material. Material costs can either be charged direct to a contract or assigned to contracts through inventory accounts. Material that is charged direct should be identified on the purchase order and material assigned through an inventory account should be consistently applied by category of material. While CAS 411 requires written policies for accounting for material, it is a best practice to establish written policies whether CAS 411 is applicable or not.
