ITEM 1A. RISK FACTORS

Your investment in the trust certificates will involve certain risks. You should carefully consider the following discussion of risks, and the other information included or incorporated by reference in the applicable prospectus supplement and the accompanying prospectus. You should also carefully consider any risk factors and other information that the underlying securities issuer may file in its Exchange Act reports as referenced in the “Documents Incorporated by Reference” section above.

IF ANY CALL WARRANT HOLDER EXERCISES ITS OPTIONAL CALL RIGHT, YOU MAY NOT BE ABLE TO REINVEST YOUR CALL PROCEEDS AT A YIELD COMPARABLE TO THE YIELD YOU WOULD HAVE RECEIVED ON YOUR TRUST CERTIFICATES

The yield you will realize on your trust certificates depends upon several factors, including:

	•		the purchase price of the trust certificates,

	•		when you acquire your trust certificates, and

	•		whether the call warrant holders exercise their optional rights to purchase outstanding trust certificates.

Although the call warrant holders are not obligated to exercise the call warrants, the yield you will realize on your trust certificates depends on whether the call warrant holders exercise their call warrants to purchase the trust certificates.

Prevailing interest rates at the time of a call exercise may be lower than the yield on your trust certificates. Therefore, you may be unable to realize a comparable yield upon reinvesting the funds you receive from the exercise of any call warrants. In addition, if the prevailing market value of the trust certificates exceeds the call exercise price paid to you upon the exercise of a call, you will not be able to realize such excess.

YOU MAY NOT BE PAID IF THE ASSETS OF THE TRUST ARE INSUFFICIENT

Currently, the trust has no significant assets other than the underlying securities. If the underlying securities are insufficient to make payments or distributions on the trust certificates, no other assets will be available for payment of the deficiency.

THE TRUSTEE WILL NOT MANAGE THE UNDERLYING SECURITIES

Except as described below, the trust will not dispose of any underlying securities, even if an event occurs that adversely affects the value of the underlying securities or that adversely affects the underlying securities issuer. As provided in the applicable trust agreement, the trust will dispose of the underlying securities only if:

	•		there is a payment default on any underlying securities,

	•		there is another type of default that accelerates the maturity of the underlying securities, or

	•		the underlying securities issuer ceases to file Exchange Act reports.

Under the first circumstance listed above, the trustee must sell the underlying securities on behalf of the trust, even if adverse market conditions exist. The trustee has no discretion to do otherwise. If adverse market conditions do exist at the time of the trustee’s sale of the underlying securities, you may incur greater losses than if the trust continued to hold the underlying securities.

THE TRUST CERTIFICATES ARE SUBJECT TO THE CREDITWORTHINESS OF THE UNDERLYING SECURITIES ISSUER

The trust certificates represent interests in obligations of the underlying securities issuer. In particular, the trust certificates will be subject to all the risks associated with directly investing in the underlying securities issuer’s unsecured subordinated debt obligations. Neither the underlying indenture nor the underlying securities place a limitation on the amount of indebtedness that may be incurred by the underlying securities issuer.

THE PAYMENTS OWED TO THE TRUST CERTIFICATEHOLDERS ARE UNSECURED OBLIGATIONS

In a liquidation, holders of the underlying securities, including the trust, will be paid only after holders of secured obligations of the underlying securities issuer. According to the underlying securities prospectus supplement relating to the issuance of the underlying securities, the underlying securities are senior unsecured indebtedness of the underlying securities issuer and rank equally with the underlying securities issuer’s existing and future senior unsecured indebtedness except as noted in such prospectus supplement.

THE RATINGS OF THE TRUST CERTIFICATES MAY CHANGE

At the time of issuance, Moody’s and/or S&P assigned ratings to the trust certificates equivalent to the ratings of the underlying securities as of the date of the applicable prospectus supplement.

Any rating issued with respect to the trust certificates is not a recommendation to purchase, sell or hold a security. Ratings do not comment on the market price of the trust certificates or their suitability for a particular investor. We cannot assure you that these ratings will remain for any given period of time or that a ratings agency would not revise or withdraw entirely the ratings if, in its judgment, circumstances (including, without limitation, the rating of the underlying securities) merit. A revision or withdrawal of a rating may adversely affect the market price of the trust certificates.
