The term sources of equity refers to capital funds provided by the owners of a company. For large corporations, this includes both paid in capital as well as retained earnings. The sources of equity available to smaller businesses or startup companies include angel investors as well as venture capital.

The excess use of leverage increases the fixed costs of a company (interest expense); thereby increasing the risk it may not be able to meet all of its financial obligations.
