The award assessed the performance of the best public companies in Indonesia and Southeast Asia based on Wealth Added Index (WAI), a calculation method developed by Stern Stewart. WAI is a metric used to measure the wealth created by a company for its shareholders.
WAI is obtained by taking the adjusted total shareholder value minus the cost of equity, which is then multiplied by market value or market capitalization.
The calculation found an increase in the number of local companies that were able to generate wealth for shareholders.
