[1] Unallocated expenses are mainly related 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 segment results as they are not reviewed by the CODM as part of segment performance.

[2] A combination of multiple business activities that do not meet the quantitative thresholds to qualify as reportable segments are grouped together as “Other Services”.

[3] The significant expenses categories and amounts align with the segment-level information that is regularly provided to the CODM.

[4] Other operating expenses for E-commerce and Digital Entertainment include general and administrative expenses, research and development expenses, and provision for credit losses net of other operating income. Other operating expenses for Digital Financial Services include general and administrative expenses, and research and development expenses net of other operating income.
