Definition of Bull & Bear FRN

Traditional FRN

C = LIBOR + 0.25%

Bull floaters

(inverse floaters or yield curve notes) C = 17.2% - LIBOR

 coupon rate as the market rate ( bond price )  attract investor who is “bullish” on bond price

Bear floaters

C = 2 LIBOR - 9.12%

 coupon rate as the market rate ( bond price )  attract investor who is “bearish” on bond price

(5)

Definition of Bull & Bear FRN

General expression for the coupon reset formula on an FRN:

C = A R + B

( C >= 0  non-negativity constraint )

C: periodic coupon rate

R: variable reference rate (ex:LIBOR)

A is characteristic parameter which determines the type of the note.

Pricing on Bull & Bear FRN

without Constraint --- Example 1

If the firm considers issuing a bull floater with C=X-LIBOR

how to determine the break-even XB such that if X<XB , a cost saving is achieved?

Firm Issuer Investor

Counterpart COF = (XB - LIBOR) + (LIBOR - 9.75%) = 10% (F)XB= 19.75% LIBOR 9.75% X-LIBOR

Pricing on Bull & Bear FRN

without Constraint --- Example 2

If the firm considers issuing a bear floater with

C=2*LIBOR-Y, how to determine the break-even YB such that if Y>YB, a cost saving is achieved?

Firm Issuer Investor

Counterpart COF = (2 LIBOR -YB) + 2(9.75% - LIBOR) = 10% (F)YB= 9.5% LIBOR 2 LIBOR - Y 9.75%

Problem

:

In example 1, the bull floater : C=19.75% - LIBOR What if LIBOR > 19.75% ?

COF = Max [0, (19.75% - LIBOR)] + (LIBOR - 9.75%) > 10%

In example 2, the bear floater : C= 2 LIBOR – 9.5% What if LIBOR < 4.75% ?

COF = Max [0, ( 2 LIBOR – 9.5%)] + 2 (9.75% - LIBOR) >10%

C >= 0

Conclusions

Equilibrium pricing condition of Bull &

Bear floaters:

Implicit rate on synthetic structure equals

the explicit alternative

Bull

: more sensitive to market rate

than fixed rate

higher interest risk

Bear

: price positively related to

market rates

negative duration

Notice the role bull & bear floaters play in interest rate risk management
