Inventories of the Company are valued at average cost or net realizable value, whichever is lower.

In accordance with adoption of ASU 2016-13, the Company evaluated and revised its policies relating to the allowance for credit losses as they pertain to contract assets, as these assets held in inventory will convert to trade receivables upon recognition of revenue for the contract to which they pertain.

In addition to contract-specific provisions for which reserves were historically established as a result of our robust contract review process, management also elected to implement a standard credit loss provision over any remaining contract assets considered to be similar low risk of credit loss.

The development of these estimates is based on historic collection trends, accuracy of contract margin reporting, as well as the expectation that collection patterns, margin accuracy, 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. Management will monitor and review the contributing factors to our reserve, and make any appropriate revisions as they become necessary.
