 EXPLANATORY NOTE
 The Registrant is filing this Amendment No. 1 (the "Amendment") to its Annual Report on Form 10-K for the fiscal year ended June 30, 2024, which was filed on August 28, 2024 (the "Form 10-K"), solely to amend the format of the audited financial statements of National Property REIT Corp. ("NPRC"), being filed as Exhibits 99.1 and 99.2 herewith, in accordance with Rule 304(e) of Regulation S-T. The Registrant previously determined that NPRC met the conditions of a significant subsidiary under Rule 1-02(w) of Regulation S-X for which the Registrant is required, pursuant to Rule 3-09 of Regulation S-X, to attach separate audited financial statements as an exhibit to its Form 10-K as of and for the years ended December 31, 2023, 2022 and 2021.
 Except as otherwise expressly noted, this Amendment does not modify or update in any way (i) the consolidated financial position, the results of operations or cash flows of the Company, or (ii) the disclosures in or exhibits to the Form 10-K; nor does it reflect events occurring after the filing of the Form 10-K. Among other things, forward-looking statements made in the Form 10-K have not been revised to reflect events that occurred or facts that became known to us after the filing of the Form 10-K, and such forward-looking statements should be read in their historical context.
