[1] The cumulative translation adjustment loss for the three months ended March 31, 2026 was primarily driven by the strengthening of the USD against the Euro (“EUR”) and Indian Rupee (“INR”), partially offset by the weakening of the USD against the Brazilian Real (“BRL”). The cumulative translation adjustment gain for the three months ended March 31, 2025 was primarily driven by the weakening of the USD against the Brazilian Real, Euro and South African Rand (“ZAR”).
