Debt Securities Meaning
- A sale of a debt security gives the investor a predetermined payment of a fixed interest in the future. At the time of maturity of the debt security, the investor gets the principal.
- The investor will receive money, or principal, when the bond reaches its maturity date (in 5 years).
- The company will pay interest on this bond every 6 months until it matures.
The investor is thus, the party on which the company is undertaking a contractual promise (obligation). In contrast to equities, debt securities are contracts, as the principal repayment is guaranteed.
Common issuers include:
- Governments.
- Corporations.
- Financial institutions.
- Municipal bodies.
How Debt Securities Work
When an issuer needs funds, it issues a debt security with:
- Face value (principal amount).
- Coupon rate (interest rate).
- Maturity period.
- Payment schedule.
Investors earn returns mainly through interest income and sometimes through capital appreciation if the security is traded in the secondary market.
Why Are Debt Securities Important?
