Liquidator filing obligations: periodic audited statements must be filed and available to creditors, with penalties for non-compliance. Section 551 requires the liquidator, where winding up exceeds one year, to file prescribed, duly audited statements at specified intervals documenting the proceedings and position of the liquidation; filings are made with the Tribunal for Tribunal windings and with the Registrar for voluntary windings, with copies to the Registrar when filed in Tribunal and additional forwarding obligations for Government companies.
