How Principal Guaranteed Notes Work
Principal Guaranteed Notes (PGNs) are issued by major financial
institutions such as Deutsche Bank, BNP Paribas and KBC Bank.
The notes carry a legal liability against these issuing institutions.
Most PGNs have a maturity range from 6 months onwards.
PGN is structured by a zero coupon bond combined with a long
position of either a put or a call option on an underlying
stock embedded in the bond. Investing in PGN is the same as
placing a deposit with the PGN issuer while using the accrued
interest income, discounted to present value, to buy a put
or call option on an underlying stock. As a result, investors
will always be repaid with at least the face value of PGN.
The embedded option however offers the possibility of profit
if the underlying stock price moves in a favorable direction.
Investors determine their individual risk/reward preferences
by making a number of choices:
i. Selecting the underlying stock
ii. Selecting the maturity date
iii. Selecting the type of option - put or call
iv. Choosing the strike (exercise) price of the option
v. Choosing the date (hence the spot price) when the PGN is
transacted
The strike price is often equal to the current market price
of the underlying stock (at-the-money put or at-the-money
call), giving investors the highest possible return when PGNs
are purchased.
PGNs are issued at par with a committed rate of profit participation
(expressed as a participation rate). The participation rate
is set at the time of purchase. The PGN is a vehicle designed
to at least protect the initial investment while offering
the possibility of gains derived from the favorable movement
of the underlying stock. When this happens the profit from
PGNs is calculated as follows: the difference between the
closing price and strike price of the underlying stock on
the fixing date multiplied by the participation rate.
For Hong Kong underlying stocks, the payoff of PGN is fixed
two business days before the PGN matures (fixing date is always
the same as the expiry date of the embedded option).
PGN has two payoff possibilities. If the underlying stock
price closes in favor to the embedded option on the fixing
date, the investor will receive the full face value of the
PGN plus a profit based on the participation rate committed
by the issuer. Conversely if the underlying stock price does
not close in favor to the embedded option, the investor will
receive back the money originally invested in the PGN.
Two types of PGN
Bull PGN means a call option is embedded, and upward
underlying stock price movement is anticipated. If the underlying
stock closes above the strike (exercise) price of the call
option a Bull PGN returns the full face value plus a profit
according to the participation rate calculation. Conversely
if the underlying stock closes at or below the strike price
of the call option, the Bull PGN only returns the full face
value.
Bear PGN means a put option is embedded, and downward
underlying stock price movement is anticipated. If the underlying
stock closes below the strike price of the put option, the
Bear PGN returns the full face value plus a profit according
to the participation rate calculation. Conversely if the underlying
stock closes at or above the strike price of the put option,
the Bear PGN only returns full face value.
Unlike a simple monetary deposit, the unique structure of
PGNs offers investors enhanced returns by forgoing the interest
income earned on the deposit and taking a bigger profit by
effectively reinvesting this income in the option. In essence
PGN is more suitable for conservative investors with a medium
to long-term view on a stock and prepared to give up deposit
interest income in return for participation in the favorable
performance of the underlying stock.

Changes in the PGN's pricing factors
lead to uncertainty over its value, and thus the investor's
principal may be affected when selling back to the issuer
before maturity. |
