This document discusses various sources of finance for companies, including debt instruments like term loans and debentures, equity like ordinary shares, and hybrid instruments such as preference shares, warrants, convertible securities, and American Depository Receipts (ADRs) and Global Depository Receipts (GDRs). Term loans are repaid over a set time period, debentures are unsecured debt, and ordinary shares represent equity ownership. Preference shares entitle holders to fixed dividends before ordinary shares, while warrants, convertible securities, and ADRs/GDRs are hybrid financial instruments.
