The revenue from products manufactured and sold by our Seamap and Klein businesses is generally recognized at a point in time, or when the customer takes possession of the product, based on the terms and conditions stipulated in our contracts with customers. Our Seamap business also provides Software Maintenance Agreements (“SMA”) to customers who have an active license for software embedded in Seamap products. The revenue from SMA’s is recognized over time, with the total value of the SMA amortized in equal monthly amounts over the life of the contract, which is typically twelve months.
