Disclosure Controls and Procedures

Our management, including our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e) and 15d-15(e)) as of September 30, 2024. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed in our periodic reports filed with the SEC (such as this Quarterly Report on Form 10-Q) has been appropriately recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure. Based on their evaluation of our disclosure controls and procedures as of September 30, 2024, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures are effective at the reasonable assurance level.

Changes in Internal Control

There were no changes in our internal control over financial reporting during the three months ended September 30, 2024 that materially affected, or are reasonably likely to materially effect, our internal control over financial reporting.
