'Capital instrument' includes all components of equity capital including ordinary equity, both voting and non-voting, and preference shares. It also includes convertible or hybrid financial instruments which are debt — like in character and which may be converted into equity (such as convertible murabaha). Also for financial institutions and insurance companies, any other financial instruments (such as subordinated debt) which are eligible as regulatory capital should also be included as capital instruments. Sukuk or senior debt instruments would not normally be regarded as "capital instruments" unless they have convertibility features. Equity-like contracts such as joint venture musharaka contracts (investments but not financing) are also included in this definition. The musharaka stake is classified as a capital instrument at onset.
