Regarding the inquiry and corresponding data years for the TESG Rating Index announcement dates:
The TESG Index was officially released at the end of March 2022, and it included historical TESG ratings data from 2015 to 2020. Therefore, when interpreting the data, the rating dates from 2015 to 2020 align with the respective annual sustainability reports.
For example, the TESG rating for the year 2020 corresponds to the sustainability report for the year 2020.
Regarding the sustainability reports for the year 2021, they were announced by September 2022. TEJ conducted two assessments in October 2022 and May 2023. For example, the assessment date would be October 2022, which corresponds to the sustainability report for the year 2021, and so on. It is recommended to consider the "Sustainability Report Year" field to understand the corresponding sustainability report year for a specific assessment date.
The update frequency for the TESG Rating Index is semi-annual, with announcements made every six months.
Prior to 2021, the assessment was updated annually. However, starting from the second half of 2022, updates occur in May and November each year. The difference between these updates lies in the daily assessment of ESG-related events and the monthly assessment of certain issues.
