[1] Unallocated expenses are mainly relating to share-based compensation, impairment of goodwill of prior acquisitions that are not under the Company’s reportable segments, and general and corporate administrative costs such as professional fees and other miscellaneous items that are not allocated to segments. These expenses are excluded from segments results as they are not reviewed by the CODM as part of segment performance.
