[3] During the fourth quarter of 2024, the Company approved and subsequently initiated a set of actions in order to reduce its cost structure, improve operational efficiencies, and realign its workforce with its strategic initiatives. As a result of these actions taken, the Company incurred estimated pre-tax restructuring and other related reorganization costs of $10 million during the six months ended June 30, 2025, which consisted of employee severance and related benefits, primarily in our Brand Tripadvisor segment. We expect that the majority of the remaining unpaid costs as of June 30, 2025 will be disbursed during the remainder of 2025.
