In addition, certain disclosures related to severe weather events and other natural conditions will be required in registrants’ annual reports. In April 2024, the SEC stayed the climate disclosure rules, pending judicial review in the Eighth Circuit, and in March 2025 the SEC voted to end its defense of the climate disclosure rules. Subsequently, on May 29, 2026, the SEC issued a formal proposal to rescind the 2024 climate disclosure rules in their entirety.	SEC Final Rule Release Nos. 33-11275; 34-99678 is effective for the Company’s annual report for fiscal year ending September 30, 2026.	The Company will continue to monitor the formal administrative outcomes of the SEC’s rescission proposal.

In the absence of such guidance, many for-profit entities historically have analogized to other GAAP, including IAS 20 or ASC 958-605, when accounting for government grants.
