PART I

ITEM 1. BUSINESS

For information with respect to the underlying securities held by PreferredPLUS Trust Series BLC-1, please refer to periodic reports of Belo Corp. (Commission file number 001-08598), including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, and other information on file with the Securities and Exchange Commission (the “SEC”). You can read and copy these reports and other information at the public reference facilities maintained by the SEC at Room 1580, 100 F Street, NE, Washington, D.C. 20549. You may obtain copies of this material for a fee by writing to the SEC’s Public Reference Section of the SEC at 100 F Street, NE, Washington, D.C. 20549. You may obtain information about the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. You can also access some of this information electronically by means of the SEC’s website on the Internet at http://www.sec.gov, which contains reports, proxy and information statements and other information that the underlying securities issuer has filed electronically with the SEC.

Although we have no reason to believe the information concerning the underlying securities or the underlying securities issuer contained in the underlying securities issuer’s Exchange Act reports is not reliable, neither the depositor nor the trustee participated in the preparation of such documents, or made any due diligence inquiry with respect to the information provided therein. No investigation with respect to the underlying securities issuer (including, without limitation, no investigation as to its financial condition or creditworthiness) or of the underlying securities has been made. You should obtain and evaluate the same information concerning the underlying securities issuer as you would obtain and evaluate if your investment were directly in the underlying securities or in other securities issued by the underlying securities issuer. There can be no assurance that events affecting the underlying securities or the underlying securities issuer have not occurred or have not yet been publicly disclosed which would affect the accuracy or completeness of the publicly available documents described above.

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 Item 1 above.

IF THE UNDERLYING SECURITIES ARE REDEEMED PRIOR TO THEIR MATURITY DATE OR IF ANY CALL WARRANT HOLDER EXERCISES ITS OPTIONAL CALL RIGHT, YOU MAY NOT BE ABLE TO REINVEST YOUR REDEMPTION OR 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,

	•		whether the underlying securities issuer exercises its option to redeem the underlying securities, and

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

The underlying securities issuer will have the right, if certain conditions are met, to redeem the underlying securities. Because the underlying securities issuer has the right to redeem the underlying securities early, we cannot assure you that the trust will be able to hold the underlying securities until their maturity date.

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

Prevailing interest rates at the time of an early redemption or 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 an early redemption or the exercise of any call warrants. In addition, if the prevailing market value of the trust certificates exceeds the redemption price or call exercise price paid to you upon a redemption of the underlying securities or 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, the underlying securities are general unsecured obligations of the underlying securities issuer, which rank on a parity with all other unsecured senior indebtedness of the underlying securities issuer. However, if the underlying securities issuer subjects any of its property to a lien then the underlying securities, and any other obligations which are then outstanding and subject to a similar covenant, will be secured ratably with the indebtedness or obligation secured by that lien and for the same length of time, subject to certain exceptions.

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.
