REVENUE |
REVENUE | NOTE 4 - REVENUE The Company generates revenue primarily from performance obligations completed under contracts with customers in two main market sectors: defense and precision industrial. The period over which the Company performs its obligations can be between three and thirty-six months. Revenue is recognized over-time or at a point-in-time given the terms and conditions of the related contracts. The Company utilizes an inputs methodology based on estimated labor hours to measure performance progress. This model best depicts the transfer of control to the customer. The Company’s contract portfolio is comprised of fixed-price contracts and provide for product type sales only. The following table presents net sales on a disaggregated basis by market and contract type: ​
