It says that Tencent has preference shares where the other two have ordinary shares. I didn't know what preference shares were so I found this:
"Preference shares are most often issued to investors, while ordinary shares are often given out to startup business founders. Preference shares give shareholders a priority when it comes to being paid company dividends, but they have less input into the strategy of the business."
