The adjustments are primarily the result of identified errors relating to value added taxes and inventory. The Company assessed the individual and aggregate impact of these adjustments on the current year and all prior periods and determined that the cumulative effect of the adjustments was not material to the full-year 2023 results, and did not result in a material misstatement to any previously issued annual or quarterly financial statements. Consequently, the Company recorded the adjustment during 2023 and has not revised any previously issued amounts in the Company’s Consolidated Financial Statements.</span></div>
