Also a floater. It is a note bearing a variable interest rate which is usually readjusted every six months. This rate is typically referenced to a money market index such as LIBOR or federal funds rate, plus a specific “fixed” spread. Almost all floating rate notes pay quarterly coupons. At the beginning of each coupon period, the coupon is determined by adding the spread to the fixing of  the reference rate at that time. For example, a floating rate note may have a coupon of 3-month LIBOR + 30 basis points.

Floating rate notes are primarily used to protect investors against upward movements in interest rates.
