  In the third quarter of 2018, the China Securities Investor Services Center (ISC) reviewed restructuring transactions implemented by listed companies from 2015 to 2017. It initiated a special online shareholder activism campaign targeting cases where target companies in restructurings failed to achieve promised performance and neglected compensation obligations.

  In early September 2018, concerning these 17 unfulfilled restructuring compensation commitments, the ISC publicly questioned the listed companies on the SSE e-Interactive (上证e互动) and SZSE Interactive Easy (深交所互动易) platforms. It exercised shareholders' rights to information, inquiry, and proposals case-by-case. The inquiries primarily focused on three aspects: First, for undisclosed performance fulfillment cases, it inquired about the progress of special audits on performance achievement and expected disclosure timelines, urging prompt disclosure to safeguard minority investors' right to know. Second, for unmet compensation obligations, it requested updates on compensation progress and measures taken by the listed companies for enforcement. Third, regarding cases where obligors were unwilling or objectively unable to compensate, it recommended that listed companies promptly pursue litigation and asset preservation measures.
