[1] Foreign currency translation adjustments included a net gain (loss) on net investment hedges of $73.1 million and $(70.8) million in 2018 and 2017, respectively.

[2] Unfavorable foreign currency translation adjustments were principally driven by a strengthening of the United States dollar against the euro.

[3] Favorable foreign currency translation adjustments were principally driven by a weakening of the United States dollar against the euro.

[4] The stranded tax effects resulting from the U.S. Tax Legislation were reclassified from AOCL to retained earnings as a result of the Company’s early adoption of an update to accounting guidance in the fourth quarter of 2017. The amount of the reclassification was calculated based on the effect of the change in the United States federal corporate income tax rate on the gross deferred tax amounts at the date of the enactment of the U.S. Tax Legislation related to items that remained in AOCL at that time.
