Notes:
⁽¹⁾ Amortization of intangible assets related to certain acquisitions
⁽²⁾ During the fourth quarters of 2022 and 2023, we initiated restructuring plans to increase efficiencies across the organization and lower the overall cost structure. Restructuring charges recorded to Cost of net revenues and operating expenses primarily related to post-employment benefits, lease termination charges and asset impairments in 2022 and post-employment benefits in 2023.
⁽³⁾ In Q4'22, we changed our methodology for the computation of the non-GAAP effective tax rate to a long-term projected tax rate and have given effect to the new methodology from January 1, 2022.
⁽⁺⁾ Changes and percentages are based on actual values. Certain tables may not sum or recalculate due to rounding. Refer to "About Non-GAAP Financial Measures" section of press release.
