Definitions:

Interest Rates

The cost of borrowing money or the return on invested capital, typically expressed as a percentage of the principal amount annually.

Maturity

Maturity is the date on which a financial obligation must be repaid or the final payment is due, marking the end of the obligation's life.

Annual Interest Payments

These are payments made to lenders or bondholders for the use of borrowed money, typically calculated annually based on the interest rate and principal amount.

Yield To Call (YTC)

The rate of interest earned on a bond if it is called. If current interest rates are well below an outstanding callable bond’s coupon rate, the YTC may be a more relevant estimate of expected return than the yield to maturity, since the bond is likely to be called.
