PART I

ITEM 1. BUSINESS

For information with respect to the underlying securities held by Public STEERS® Series 1998 HLT-1 Trust, please refer to Hilton Hotels Corporation’s (Commission file number 001-03427) periodic reports, 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, N.E., 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, N.E., 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 reports referenced in Item 1 above.

DISTRIBUTION OF UNDERLYING SECURITIES

If there is a payment default on the underlying securities or any other default on the underlying securities that results in an acceleration of their maturity, then the underlying securities will be distributed to you in accordance with the allocation ratio as described in the applicable prospectus supplement. In either case, the timing and amount of payments with respect to the principal of, premium on, if any, and any interest to be distributed in respect of the underlying securities may be materially and adversely affected. In addition, there can be no assurance that the market value of the underlying securities will not decline from the time of such occurrences to the time the underlying securities are distributed to you.

LIMITED ASSETS

The trust has no significant assets other than the underlying securities and the underlying securities are the sole assets of the trust that are available to make distributions in respect of the trust certificates. 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.

GAMING REGULATION AND LICENSING

The ownership and operation of casino gaming facilities are subject to extensive governmental regulation. The underlying securities issuer holds gaming licenses or permits in each jurisdiction in which it operates gaming activities (each, a “Gaming License” and, collectively, “Gaming Licenses”). Gaming Licenses and related approvals, however, are deemed to be privileges under the laws of the jurisdictions in which the company conducts gaming activities, and no assurances can be given that any new Gaming Licenses that may be required in the future will be granted or that existing Gaming Licenses will not be revoked or suspended. There can be no assurance that such a revocation or suspension would not have a material adverse effect on the underlying securities issuer’s business activities or results of operations.

NO MANAGEMENT OF UNDERLYING SECURITIES

Except as described herein, the trust will not dispose of any underlying security, regardless of adverse events, financial or otherwise, that may affect the value of the underlying securities or the underlying securities issuer. If there is a payment default on the underlying securities or any other default on the underlying securities that results in an acceleration of their maturity, the trust will deal with the underlying securities only in the manner provided in the applicable trust agreement. If such a default occurs, the applicable trust agreement will provide that the trustee will distribute underlying securities to you in accordance with the allocation ratio (as described in the applicable prospectus supplement) notwithstanding market conditions at that time, and the trustee will have no discretion to do otherwise.

CREDIT RISK

The trust certificates represent interests in obligations of a single obligor. In particular, the trust certificates will be subject to all the risks associated with a direct investment in unsecured debt obligations of the underlying securities issuer.

PAYMENTS IN RESPECT OF TRUST CERTIFICATES ARE UNSECURED

In a liquidation, holders of the underlying securities 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, but which are effectively subordinated to the underlying securities issuer’s existing and future senior secured indebtedness to the extent of the collateral therefor.

RATINGS OF THE TRUST CERTIFICATES SUBJECT TO CHANGE

At the time of issuance, the trust certificates had ratings assigned by Moody’s and S&P 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 in as much as such ratings do not comment on the market price of the trust certificates or their suitability for a particular investor. We cannot assure you that the ratings will remain for any given period of time or that the ratings will not be revised or withdrawn entirely by the related rating agency if, in its judgment, circumstances (including, without limitation, the rating of the underlying securities) so warrant. A revision or withdrawal of such rating may have an adverse effect on the market price of the trust certificates.
