What type of preference shares allows shareholders to receive additional dividends beyond the fixed rate?

Participating shares are a specific type of preference shares that grant shareholders the right to receive extra dividends beyond the fixed rate specified in the original agreement. This feature typically allows shareholders to benefit from the company's profitability by participating in surplus earnings when the company performs well financially and declares additional dividends. Unlike other preference shares, participating shares do not just receive fixed dividends; they often participate in the distribution of proceeds after common shareholders receive their share, effectively allowing for a more equitable return based on the company's overall performance.

The unique advantage of participating shares lies in this potential for additional income, making them appealing to investors seeking a greater share of the company's profits. Thus, when considering how preference shares can offer a higher return under certain conditions, participating shares stand out as the correct choice in this context.
