Extendible reset bonds are floaters in which the issuer is required to reset the coupon rate so that the issue will trade at a predetermined price (usually above the face value). The coupon rate of this type of floaters is based on the margin required by the market at the reset date for the security to trade at par value. On the reset date, the coupon rate is usually calculated as the average of rates suggested by two investment banking firms. The new rate not only reflects the level of interest rate at the reset date, but also the margin required by the market on the reset date.

For example, assume that the formula for extendible reset bond is 5.5% of MIBOR plus 125 basis points. At coupon reset date, investment bankers suggest that a margin of 150 basis points is to be maintained for the bond to trade above par. Based on the suggestion of the investment bankers, on reset date, the issuer resets the coupon rate to 5.5% of MIBOR plus 150 basis points.
