Recent tax legislation						Effective July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was signed into law. Certain provisions of OBBBA modified U.S. tax law and impact us and our shareholders. Among other changes, this legislation (i) permanently extended the 20% deduction for “qualified REIT dividends” for individuals and other non-corporate taxpayers under Section 199A of the Code, (ii) permanently reinstated 100% bonus depreciation for certain property acquired after January 19, 2025, (iii) increased the percentage limit under the REIT asset test applicable to taxable REIT subsidiaries from 20% to 25% for taxable years beginning after December 31, 2025, and (iv) increases the base on which the 30% interest deduction limit under Section 163(j) of the Code applies by excluding depreciation, amortization and depletion from the definition of “adjusted taxable income” for taxable years beginning after December 31, 2024. The provision of OBBBA did not have a material impact to our Consolidated Financial Statements.
