Inventories of the Company are valued at average cost or net realizable value, whichever is lower. Contract assets consist of costs and earnings in excess of billings, retainage, and other unbilled amounts generated when revenue recognized exceeds the amount billed to the customer.

The Company records appropriate provisions related to the allowance for credit losses associated with contract assets, as these assets held in inventory will convert to trade receivables once the customer is billed under the contract to which they pertain. Provisions are recorded based on the specific review of individual contracts as necessary, and a standard provision is recorded over any remaining contract assets pooled together based on similar low risk of credit loss. The development of these provisions are based on historic collection trends, accuracy of estimates within contract margin reporting, as well as the expectation that collection patterns, margin reporting, and bad debt expense will continue to adhere to patterns observed in recent years. These expectations were formed based on trends observed as well as current and expected future conditions.
