On August 20, 2013 CEO (0883.HK) declared an interim dividend of 0.25 HKD per ordinary share. This works out to a dividend of $3.225 per ADR share - an increase of 66% over last year's interim dividend.
The calculation is as follows:
100 ordinary shares to 1 ADR share = 25.00 HKD per ADR share
Assuming an exchange rate of 1 HKD to 0.129 USD = $3.225 per ADR
Take out the 10% foreign tax and the net dividend should be $2.9025 per share.
Ex-Dividend Date is September 5, 2013
Payable Date is October 10, 2013
This works to a 3.34% yield on an annual basis (net of foreign tax on interim and year-end dividends).
