Private placement disclosure requirement: general information and key information documents govern listing and update obligations for offers. Regulation 50A mandates that issuers making private placements of non-convertible securities and seeking listing must file a general information document with prescribed disclosures, valid for one year and replaceable for subsequent offers by a key information document; key information documents must update offer details, financials older than six months, material changes or developments, and applicable schedule disclosures, with postings to the stock exchange website and financial-timing requirements subject to limited interim unaudited disclosures for compliant listed issuers and their subsidiaries.
