[1] Common stock outstanding decreased by approximately three million net shares during the year ended December 31, 2022.

[2] The Accumulated Other Comprehensive Loss balance primarily reflects foreign currency translation adjustments.

[3] There were no material reclassifications from accumulated other comprehensive loss reflected in other comprehensive income (loss) during 2023 or 2022. There was no material tax impact related to the foreign currency translation adjustments. In 2021, we remitted the cumulative amount of identified cash in our foreign operations in excess of near-term working capital needs. We continue to expect that the remaining balance of our undistributed foreign earnings will be indefinitely reinvested. If we determine that all or a portion of such foreign earnings are no longer indefinitely reinvested, we may be subject to additional foreign withholding taxes and U.S. state income taxes. There were no material taxes associated with other comprehensive income (loss) during 2023 or 2022.

[4] In January 2023, our Board of Directors approved our first-ever quarterly dividend program (accordingly, there were no dividends declared during 2022). We declared dividends of $1.48 per share during the three months ended March 31, 2023.
