In November 2022, we initiated a restructuring plan to reduce our cost structure to better align the operational needs of the business to current economic conditions while continuing to support our long-term strategy. This restructuring includes the reduction of headcount as well as the abandonment of certain lease contracts and the cancellation of contractual services arrangements with certain suppliers. As of December 31, 2023, we have substantially incurred all costs pertaining to restructuring activities, with related cash outflows extending until the fourth quarter of 2024.

The restructuring liabilities are included in accrued liabilities in the consolidated balance sheets. The restructuring charges are included in others in the consolidated statements of comprehensive loss. Restructuring activities for the year ended December 31, 2023 are as follows:
