Running yield
The annual interest payment (dividend) divided by the current market price of a bond.
The maturity value of a bond is the amount of money that an investor will be repaid when a bond’s term ends.
The maturity value may also be called a bond’s face value, the principal, or par.
This value is typically reflective of the amount of money that has been borrowed by the issuer of the bond, excluding interest payments.
In the case of a zero coupon bond, the maturity value represents both the original amount borrowed, plus an additional sum that represents the return on the bond that the borrower receives in return for the loan.
