(1) As of the year ended December 31, 2023, the Company updated its methodology for determining the country of origin for its sales. Sales are now recorded by shipping country rather than billing country. The Company updated the methodology retrospectively, adjusting the prior year presentation for all regions presented. (2) The line item presented above previously bifurcated sales between the United States and Canada. Due to the updated methodology for determining the country of origin for sales, it was noted that Canada no longer was a material location to separately disclose. Canada sales have been included within the "Other" line item in the table above and United States sales have been retained as a single line item to more accurately reflect origin of sales for material regions.
