Share capital classification establishes equity and preference shares with specified dividend, repayment priorities and differential rights. Section 43 distinguishes equity share capital from preference share capital: equity comprises share capital without preferential rights, including shares with ordinary voting or differential rights; preference share capital is defined by preferential dividend rights (fixed amount or rate) and/or preferential repayment on winding up, and remains preference capital even if it also participates in surplus dividends or winding-up proceeds after repayment.
