Floating rate note

Floating rate notes (FRNs) are bonds that have a variable coupon, equal to a money market reference rate, like LIBOR or federal funds rate, plus a quoted spread (also known as quoted margin). The spread is a rate that remains constant. Almost all FRNs have quarterly coupons, i.e. they pay out interest every three months. At the beginning of each coupon period, the coupon is calculated by taking the fixing of the reference rate for that day and adding the spread. A typical coupon would look like 3 months USD LIBOR +0.20%.

In the United States, government sponsored enterprises (GSEs) such as the Federal Home Loan Banks, the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac) are important issuers. In Europe, the main issuers are banks.

Some FRNs have special features such as maximum or minimum coupons, called "capped FRNs" and "floored FRNs". Those with both minimum and maximum coupons are called "collared FRNs".

"Perpetual FRNs" are another form of FRNs that are also called irredeemable or unrated FRNs and are akin to a form of capital.

FRNs can also be obtained synthetically by the combination of a fixed rate bond and an interest rate swap. This combination is known as an asset swap.

A deleveraged floating-rate note is one bearing a coupon that is the product of the index and a leverage factor, where the leverage factor is between zero and one. A deleveraged floater, which gives the investor decreased exposure to the underlying index, can be replicated by buying a pure FRN and entering into a swap to pay floating and receive fixed, on a notional amount of less than the face value of the FRN.
