Debt Financing: Whenever a firm raises money for the working capital or capital expenses by selling bonds, bills, or notes to individual and or institutional investors. In return for lending money, the individuals or institutions become creditors and obtain a promise that the principal and interest on the debt will be paid back.
Debt financing comprises both secured and un-secured loans. Security includes a form of collateral as an assurance that the loan will be paid back. When the debtor defaults on the loan, that collateral is forfeited to please payment of the debt. Most of the lenders will ask for some sort of security on loan. Few, when any, will lend you money based on your name or idea by yourself.
