Based upon the evaluation described above, our principal executive officer and our principal financial and accounting officer have concluded that they believe our disclosure controls and procedures were effective as of the end of the period covered by this report, in providing reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and our principal financial and accounting officer, to allow timely decisions regarding required disclosures, and is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.\n\n \n\n*Changes in Internal Control over Financial Reporting*\n\n \n\nOur management, with the participation of our principal executive officer and our principal financial and accounting officer, has evaluated whether any change in our internal control over financial accounting and reporting occurred during the quarter ended March 31, 2026. During the period covered by this report, we have concluded that there were no changes during the fiscal quarter in our internal control over financial reporting, as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act, which have materially affected, or are reasonably likely to materially affect, our internal control over financial accounting and reporting.\n\n \n\n27\n\n[Table of Contents](#toc)\n\n \n\n \n\n**PART II.
