Note 4 - Revenue (continued)

When reviewing revenue by sales channel, the Company separates net sales to original equipment manufacturers ("OEMs") from sales to distributors and end users. The following table presents the percent of revenue by sales channel for the six months ended June 30, 2022 and 2021, respectively:

	Six Months Ended	Six Months Ended
Revenue by sales channel	June 30, 2022	June 30, 2021
Original equipment manufacturers	60%	61%
Distribution/end users	40%	39%

In addition to disaggregating revenue by segment, 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 six months ended June 30, 2022 and June 30, 2021, approximately 9%, 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. Approximately 4% of total net sales represented service revenue during the six months ended June 30, 2022 and June 30, 2021, respectively. Finally, business with the United States ("U.S.") government or its contractors represented approximately 6% and 7% of total net sales during the six months ended June 30, 2022 and June 30, 2021, respectively.

Remaining Performance Obligations:

Remaining performance obligations represent the transaction price of orders meeting the definition of a contract 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 $245.5 million at June 30, 2022.
