[1] The cumulative translation adjustment loss for the six months ended June 30, 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 six months ended June 30, 2025 was primarily driven by the weakening of the USD against the Euro, Brazilian Real and Mexican Peso ("MXN").
