[1] Includes realized and unrealized gains and losses on derivative currency forward and option contracts not designated as hedging instruments, as well as the ineffective portion of certain interest rate swap contracts that have been de-designated from hedge accounting. For contracts not designated as hedging instruments, we realized (losses) gains of ($14,169), $2,706 and $(1,078), respectively, for the fiscal years ended June 30, 2026, 2025, and 2024. Refer to Note 4 for additional details relating to our derivative contracts.
[2] Currency-related (losses) gains, net primarily relates to significant non-functional currency intercompany financing relationships that we may change at times and are subject to currency exchange rate volatility. In addition, during all fiscal years presented, we had certain cross-currency swaps designated as cash flow hedges, which hedge the remeasurement of certain intercompany loans; refer to Note 4 for additional details relating to these cash flow hedges.
[3] On May 1, 2020, we entered into a financing arrangement, which included 7-year warrants to purchase 1,055,377 of our ordinary shares with a strike price of $60. The effect of the warrants on our weighted-average shares outstanding for a period is dilutive if the average market price of our ordinary shares during the period was higher than the strike price of the warrants and anti-dilutive if the average market price of our ordinary shares during the period was lower than the strike price of the warrants.
