So - about this SPP, page-20

If you buy on market you might get a better price, and would have if you bought lower, but the shareholder interested in stumping up and sending cash into the raising for the purpose it is intended should just go via the spp route. The market usually follows to the raising price and then tends to flow upward on the cash value the raising caused/inflated the balance sheet created, and then more so when the company purchase starts to show increased value. So, a hard decision, but I'd doubt based on the stellar longterm perfomance of this company you will go wrong either way and certainly wont be wrong in 6 months time.
