年报更正公告
Regulatory Filings Classification · 95% confidence The document is titled '年报更正公告' which translates to 'Annual Report Correction Announcement'. It references the company's 2013 Annual Report and specifies corrections to shareholder information disclosed in that report. The document is relatively short (2274 characters) and serves to correct previously published annual report data rather than presenting the full annual report itself. It explicitly states that other content of the 2013 Annual Report remains unchanged and apologizes for any inconvenience caused. This fits the pattern of a report publication announcement or correction notice rather than the full annual report. According to the rules, such a correction announcement should be classified as a Regulatory Filing (RNS) because it is a regulatory announcement correcting prior disclosures and does not contain the full financial report or substantive financial data itself.
