Revisions in the estimated gross profits on contracts and contract amounts are made in the period in which the circumstances requiring the revisions occur. During the nine months ended September 30, 2017, the effect of such revisions in total estimated contract profits resulted in a decrease to the total gross profit to be earned on the contracts of approximately $1,684,000 from that which would have been reported had the revised estimates been used as the basis of recognition of contract profits in prior years, excluding the effect of the A-10 contract. During the nine months ended September 30, 2016, the effect of such revisions was a decrease to total gross profit of approximately $1,627,000. Although management believes it has established adequate procedures for estimating costs to uncompleted open contracts, it is possible that additional significant costs could occur on contracts prior to completion. |
