[3] Includes allocated corporate general and administrative personnel costs from our Tripadvisor Core segment of $2 million, $3 million and $2 million for the years ended December 31, 2022, 2021 and 2020, respectively.

[4] Includes allocated corporate general and administrative personnel costs from our Tripadvisor Core segment of $3 million, $3 million and $2 million for the years ended December 31, 2022, 2021 and 2020, respectively. (4) The Company incurred a loss of approximately $8 million during the fourth quarter of 2022, as the result of external fraud. This loss was recorded to general and administrative expenses on the consolidated statement of operations for December 31, 2022. The Company considers such costs to be non-recurring in nature. To the extent the Company recovers any losses in future periods related to this incident, the Company plans to reduce Adjusted EBITDA by the recovery amount in that same period.
