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 annual Software Maintenance Agreements (“SMA”) to customers who have an active license for software imbedded in Seamap products. The revenue from SMA is recognized over time, with the total value of the SMA amortized in equal monthly amounts over the life of the contract. The following table presents revenue from contracts with customers disaggregated by geography, based on shipping location of our customers:

Considering the products manufactured and sold by our Marine Technology Products business and the Company’s standard contract terms and conditions, we expect our contract assets and liabilities to turn over, on average, within a three to six-month period. With respect to the disclosures above, sales and transaction-based taxes are excluded from revenue, and we do not disclose the value of unsatisfied performance obligations for contacts with an original expected duration of one year or less. Also, we expense costs incurred to obtain contracts because the amortization period would be one year or less. These costs are recorded in selling, general and administrative expenses.
