Explanation of Responses:

Remarks:

This Form 3, reporting an event occurring on February 23, 2026, is being filed late due to the reporting person's inability to obtain EDGAR access credentials prior to the applicable filing deadline, notwithstanding the initial submission of a completed Form ID application and related documents before such deadline. The reporting person is relying on the SEC Staff no-action position (Question 7, March 12, 2026), which provides relief for Section 16(a) filers who submitted a completed Form ID before a filing deadline falling between December 18, 2025 and March 18, 2026 but did not receive EDGAR access by the applicable filing deadline.

No securities are beneficially owned.
