A Step-Up Note is a type of bond with a coupon rate that increases over time according to a contractual schedule as shown below. The Note pays coupons semi-annually on May 15 and November 15 and has a term to maturity of 6 years. Assume today is November 15 so there is exactly 6 months to the next coupon. Par is $1,000. The Step-Up Note differs from the typical bond because the coupons cannot be treated as an ordinary annuity [a fixed cash flow for a limited term] so the PMT key on the calculator cannot be used. The Note is a semi-annual series of unequal cash flows for a limited time period.
