Shelf prospectus eligibility: qualifying issuers may file shelf prospectuses subject to financial, rating, disclosure and issuance limits. The amendment permits specified issuers to file a shelf prospectus for public issuance of debt securities, defines key terms by reference to the Companies Act, lists eligible entities and financial, rating and conduct criteria (including net worth, profit track record, minimum rating, absence of regulatory action and no defaults), requires filing an information memorandum with exchanges and the Board containing Companies Act disclosures, a term sheet, rating updates and financial ratios, and limits issuances under one shelf prospectus to four.
