A floating-rate note (floater) in which the reference rate is magnified by a factor λ (where λ > 1). Therefore, the rate on this note is the difference between the multiple-adjusted reference rate less a fixed rate or spread:

Rate on super floater = λ (reference rate) – fixed rate

The first expression represents the coupon of the note (usually it is a multiple of a specific market interest rate such as LIBOR).

This instrument allows investors to receive an above-market initial yield, while linking subsequent coupon adjustments to a given point on the yield curve.

It is also known as a leveraged floating-rate note, a leveraged floater, or a supercharged floater.
