Optimal exercise

  • (^) At a discount: If a bond is bought at a discount and it has a Bermudan option with call dates at coupon dates and redemption amount C independent of the time it is called, then the smallest yield occurs if the bond is not called before maturity
  • At a premium: If a bond is bought at a premium and it has a Bermudan option with call dates at coupon dates and redemption amount C independent of the time it is called, then the smallest yield occurs if the bond is called at the earliest call date

Optimal exercise

  • (^) At a discount: If a bond is bought at a discount and it has a Bermudan option with call dates at coupon dates and redemption amount C independent of the time it is called, then the smallest yield occurs if the bond is not called before maturity
