Amendment Description	Watermark Lodging Trust, Inc. (“WLT” or the “Company”) is filing this Amendment No. 1 on Form 10-K/A (this “Amendment”) to amend the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, originally filed with the Securities and Exchange Commission (the “SEC”) on March 28, 2022 (the “2021 10-K”), to include the information required by Items 10 through 14 of Part III of Form 10-K. This information was previously omitted from the 2021 10-K in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above referenced items to be incorporated in the Form 10-K by reference from the Company’s definitive proxy statement if such statement is filed nolater than 120 days after the Company’s fiscal year-end. We are filing this Amendment to provide the information required in Part III of Form 10-K because a definitive proxy statement containing such information will not be filed by the Company within 120 days after the end of the fiscal year covered by the 2021 10-K.This Amendment amends and restates in their entirety Items 10, 11, 12, 13 and 14 of Part III of the 2021 10-K, and amends the exhibit index set forth in Part IV of the 2021 10-K to add certain exhibits as noted herein. The cover page of the 2021 10-K is also amended to delete the reference to the incorporation by reference of the Company’s definitive proxy statement.Except as described above, no other changes have been made to the 2021 10-K, and this Amendment does not modify, amend or update in any way any of the financial or other information contained in the 2021 10-K. This Amendment does not reflect events occurring after the date of the filing of our 2021 10-K. Accordingly, this Amendment should be read in conjunction with our 2021 10-K and with our filings with the SEC subsequent to the filing of our 2021 10-K. Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), this Form 10-K/A also contains a certification pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, which is attached hereto. Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. Terms used but not defined herein are as defined in our 2021 10-K.
