Disaggregation of Revenues

The Company disaggregates its revenue from contracts with customers by geographic region based on the primary billing address of the customer and timing of transfer of goods or services to customers (point-in-time or over time), as it believes it best depicts how the nature, amount, timing and uncertainty of its revenue and cash flows are affected by economic factors. Total revenue for the years ended December 31, 2022, 2021 and 2020, based on the disaggregation criteria described above are as follows (in thousands):

	Year Ended December 31,
	2022					2021					2020
	Revenue		% of Revenue			Revenue		% of Revenue			Revenue		% of Revenue
Revenue by primary geographical market:
North America	$	2,965		71	%	$	8,816		95	%	$	4,225		88	%
EMEA		1,085		26	%		232		3	%		497		10	%
Asia		142		3	%		217		2	%		121		2	%
Total	$	4,192		100	%	$	9,265		100	%	$	4,843		100	%
Revenue by timing of recognition:

Total	$	4,192		100	%	$	9,265		100	%	$	4,843		100	%

The point in time revenue was primarily related to the product revenue and overtime revenue was from non-recurring engineering services.

For the year ended December 31, 2022 and 2021, one customer accounted for 81% and 80% of the Company’s revenue, respectively. For the year ended December 31, 2020, three customers accounted for 65%, 11%, and 10%, respectively, of the Company’s revenue.

Contract Assets and Contract Liabilities

As of December 31, 2022 and 2021, the Company had contract assets of $0.2 million and $4.1 million, respectively, recognized in other current assets. The Company had no contract liability, as of December 31, 2022 and 2021.

As of the year ended December 31, 2022, the Company anticipated a contract modification with one of its customers which would result in a change in the overall transaction price under the arrangement. Accordingly, the effect the contract modification had on the transaction price has been recognized on a cumulative catch-up basis, resulting in a decrease of the revenue and contact asset balance by approximately $3.9 million.
