When reviewing revenues by sales channel, the Company separates net sales to OEMs from sales to distributors and end users. The following table presents the percent of revenues by sales channel for the year ended December 31, 2019 and December 31, 2018:    

Revenue by sales channel	December 31, 2019	December 31, 2018
Original equipment manufacturers	56%	56%
Distribution/end users	44%	44%

In addition to disaggregating revenue by segment and geography and by sales channel as shown above, the Company believes information about the timing of transfer of goods or services, type of customer and distinguishing service revenue from product sales is also relevant. During the year ended December 31, 2019 and December 31, 2018, approximately 12% and 10%, respectively, of total net sales were recognized on an over-time basis because of the continuous transfer of control to the customer, with the remainder recognized as of a point in time. The payment terms with the U.S. government or its contractors, which represented approximately 8% and 7% of total net sales for 2019 and 2018, respectively, differ from those of non-government customers. Finally, approximately 5% of total net sales represented service revenue in both 2019 and 2018.

Remaining Performance Obligations:

Remaining performance obligations represent the transaction price of orders meeting the definition of a contract in the new revenue standard for which work has not been performed and excludes unexercised contract options. Performance obligations having a duration of more than one year are concentrated in contracts for certain products and services provided to the U.S. government or its contractors. The aggregate amount of the transaction price allocated to remaining performance obligations for such contracts with a duration of more than one year was approximately $204.6 million at December 31, 2019.
