An NVDR, or non-voting depository receipt, is a new trading instrument issued by Thai NVDR. It is a valid security as specified by SEC and is automatically regarded as a listed security by SET.
The main purpose of NVDRs is to stimulate trading activities in the Thai stock market. By investing in NVDRs, investors receive the same financial benefits (i.e., dividends, right issues or warrants), as those who invest directly in a company's ordinary shares. The only difference between investing in NVDR and company shares is in regard to voting. Unlike ordinary shareholders, NVDR holders cannot be involved in company          decision-making. Both thai and foreign investors can invest in NVDRs.
