On May 31, 2011, upon application of a major creditor, Grande was placed into provisional liquidation when the High Court of Hong Kong appointed joint and several provisional liquidators (“Provisional Liquidators”) over Grande.

In May 2014, Grande, the Provisional Liquidators and a creditor of Grande entered into an agreement to implement the “Grande Restructuring Plan” submitted by a creditor of Grande.

As at June 15, 2017 the shareholding has increased to 73.5%.
