Each segment engages in business activities which generate revenues and incur expenses. Based upon the information provided to the Company’s chief operating decision maker (“CODM”) to make decisions on resource allocation and operating performance evaluation, the Company has determined that it has three reportable segments.

The Company organizes its business segments along reporting lines and has three operating segments, consisting of the North Asia region, the Thailand region and the Rest of the World (“ROW”) region. The Company considers the economic characteristics similarity in determining the reportable segments.

As the three operating segments exceed the quantitative thresholds, they are also reportable segments. The accounting policies for segment information, including transactions entered between segments are generally the same as those described in the summary of significant accounting policies.

Inter-segment revenues are eliminated upon consolidation and reflected in the “adjustments and eliminations” column. All other adjustments and eliminations are part of detailed reconciliations presented further below.
