Headline and basic earnings In terms of paragraph 3.4(b) of the Listings Requirements of the JSE Limited (JSE), a company listed on the JSE is required to publish a trading statement as soon as they are satisfied that a reasonable degree of certainty exists that the financial results for the period to be reported upon next will differ by at least 20% from the financial results for the previous corresponding period.
