sdl's takeover defence, page-5

I'm very much expecting another take-over offer in the next week or two.

I do not however, want to sell my SDL shares until the company is producing. There are too many regional opportunities that SDL will face after they have paid off the Capex and can re-invest their profits into neighboring deposits- as they already would have the infrastructure under their terms.

How many days after a substantial holder buys or sells shares do they have to report it as a change in substantial holding on the ASX?
