  • Bonds: Long-term debt instruments issued by corporations, municipalities, and governments to raise capital.

Mathematical Models

Debt instruments often involve interest calculations, such as the formula for bond pricing:

$$ P = \sum_{t=1}^{n} \frac{C}{(1+r)^t} + \frac{F}{(1+r)^n} $$

Where:

  • \( P \) = Price of the bond
  • \( C \) = Coupon payment
  • \( r \) = Discount rate
  • \( n \) = Number of periods
  • \( F \) = Face value of the bond
