The Stock Exchange of Thailand is asking the government to allow Dual Class of Share, where shares carry different voting rights (for example 1 share with 2 or 5 votes) while dividends stay equal. Owners could sell more shares to the public (free float from about 15% to about 40%) and still keep control. It is only a proposal: legal changes are needed, the rules for already-listed companies are unresolved, and the hope is to see it in concrete form this year. For most small owners this is background; it matters only if you plan to raise capital through the stock market.
