Preference shares, along with common shares, are two primary types of stocks that companies offer to investors. Preference shareholders have priority rights over ordinary shareholders in distribution of profits and residual assets.

Unlike common shares, preference shares function more like a bond. They are rated by major credit-rating companies and their prices are affected by change in interest rates.
