Koscinski, Joseph Steven
Please note that due to the planned shutdown of Webb-site.com,
the directors, officers and advisers of HK-listed companies will cease to be updated effective 2025-03-31. Appointments
and resignations effective on or before that date will be recorded, as will advisers recorded in annual reports
filed on or before that date. We intend to make a data dump available after processing the final filings.
