Effective February 1, 2018 the Company adopted the New Revenue Standard using the modified retrospective method applied to those contracts which were not completed as of February 1, 2018. Results for reporting periods beginning after January 31, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 605.

Under the New Revenue Standard, revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. The Company has determined that the New Revenue Standard applies to contracts performed by the businesses in our Marine Technology Products segment, but not to contracts performed by our Equipment Leasing segment which are within the scope of other revenue recognition standards.

The impact of adopting the New Revenue Standard was not material, as the analysis of our contracts under the New Revenue Standard supports the recognition of revenue at a point in time for the majority of our contracts, which is consistent with our current revenue recognition model. As a result, the Company did not record an adjustment to opening retained earnings as a result of the adoption of the New Revenue Standard.

The revenue from products manufactured and sold by our Seamap and Klein businesses, as well as the revenue from products marketed and sold by our SAP business, 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 imbedded 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.
