Preference shares have characteristics of both equity shares and debentures. Like equity, there are no obligatory dividend payments but dividends are not tax deductible. Like debentures, dividends provide a fixed rate of return but preference shareholders have priority over equity shareholders for dividends and assets in liquidation. Preference shares can also be redeemed or perpetual, cumulative or non-cumulative, and convertible or non-convertible. Voting rights for preference shares are now restricted except if dividend arrears exceed two years.
