Amounts may not exceed their net realizable value. Under the typical payment terms of our government contracts, the customer retains a portion of the contract price until completion of the contract, as a measure of protection for the customer. Our government contracts therefore typically result in revenue recognized in excess of billings, which we present as contract assets. Contract assets are classified as current. The Company’s contract liabilities represent customer payments received or due from the customer in excess of revenue recognized. Contract liabilities are classified as current.
