更正公告
Regulatory Filings Classification · 95% confidence The document is a correction announcement related to previously disclosed 2017 semi-annual reports and an associated related-party transaction announcement. It corrects data tables and monetary units in the earlier reports and announcements. The document length is short (1639 characters) and it does not contain the full semi-annual report or financial statements itself, but rather corrections to those reports. It also states that the corrected reports are disclosed elsewhere. Therefore, this document is an announcement correcting previously published reports, not the reports themselves. According to the rules, such a document is best classified as a Regulatory Filing (RNS) because it is a correction announcement that does not fit other categories and is not the full report itself.
