ITEM 1A. RISK FACTORS

THE UNDERLYING SECURITIES ISSUER HAS FILED FOR BANKRUPTCY. NO FURTHER PAYMENTS WILL BE MADE ON THE TRUST CERTIFICATES.

On April 14, 2020, Frontier Communications Corporation, the issuer of the Underlying Securities, and certain of its direct and indirect subsidiaries filed a Chapter 11 voluntary petition in the United States Bankruptcy Court for the Southern District of New York. This filing resulted in an acceleration of the Underlying Securities. As a result of such event, The Bank of New York Mellon, as Trustee for the Trust was directed under Section 3.04 of the Standard Terms and the definition of Distribution Election under the Series Supplement to distribute the principal amount of Underlying Securities pro rata to the Certificateholders. On May 11, 2020, the Trustee began making distributions of the Underlying Securities upon presentation of the Certificates for cancellation. The Trust will terminate following the distribution of all Underlying Securities. As of this date, the distributions are still ongoing and the Trust has not yet been terminated. For more information regarding this matter or for how to surrender your Certificates, please see:

Report of Independent Accountants

To the Board of Directors and Management of Merrill Lynch Depositor, Inc.:

We have examined the accompanying management assertion of Merrill Lynch Depositor, Inc. (the “Company”), that the Company complied with the PPLUS Minimum Servicing Standards with respect to the PreferredPLUS Trust Series CZN-1 as set forth in Appendix I as of and for the year ended December 31, 2020. The Company’s management is responsible for its assertion. Our responsibility is to express an opinion on management's assertion about the Company’s compliance with the specified requirements based on our examination.

Our examination was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants. Those standards require that we plan and perform the examination to obtain reasonable assurance about whether management's assertion about compliance with the specified requirements is fairly stated, in all material respects. An examination involves performing procedures to obtain evidence about whether management’s assertion is fairly stated, in all material respects. The nature, timing and extent of the procedures selected depend on our judgment, including an assessment of the risks of material misstatement of management’s assertion, whether due to fraud or error. We believe that the evidence we obtained is sufficient and appropriate to provide a reasonable basis for our opinion.

Our examination does not provide a legal determination on the Company’s compliance with the specified requirements.

In our opinion, management’s assertion that the Company complied with the PPLUS Minimum Servicing Standards with respect to PreferredPLUS Trust Series CZN-1 as set forth in Appendix I as of and for the year ended December 31, 2020 is fairly stated, in all material respects.
