During the year ended December 31, 2023, we determined that triggering events occurred which indicated that the carrying value of our right-of-use (“ROU”) and other lease-related assets related to a change in usage of certain idle office space at our corporate headquarters in Boston, Massachusetts as well as idle office spaces located in Plano, Texas, Los Angeles, California, and Toronto, Canada may not be fully recoverable. As a result, we utilized discounted cash flow models to estimate the fair value of the asset groups taking into consideration the time period it will take to obtain sublessees, the applicable discount rate and the anticipated sublease income and calculated the corresponding impairment loss. We used prices and other relevant information generated by recent market transactions involving similar or comparable assets, as well as our historical experience in real estate transactions. In the year ended December 31, 2023, we recorded impairment losses of $30.8 million, respectively, related to these idle office spaces, consisting of $22.2 million, related to ROU assets and $8.6 million related to leasehold improvements associated with these leased office spaces.
