[1] During the fourth quarter of 2015, we incurred an expense in the amount of $67 million to reflect a non-cash contribution to The TripAdvisor Charitable Foundation (the “Foundation”), which was recorded to general and administrative expense in our consolidated statement of operations. TripAdvisor had historically funded 2% of its annual operating income before amortization and stock-based compensation. TripAdvisor’s pledge agreement provided for an immediate satisfaction of all future annual contributions, by paying an amount equal to eight multiplied by TripAdvisor’s prior year contribution to the Foundation. TripAdvisor exercised this right under its pledge agreement in December 2015. We settled this obligation in treasury shares based on the fair value of our common stock on the date the treasury shares were issued to the Foundation and therefore given the use of stock to settle the obligation, the amount has been excluded from Adjusted EBITDA. TripAdvisor does not expect to make any future contributions to the Foundation.
