This may be a stupid question, but i'll ask anyway...

If i decide to accept the offer and purchase more shares, when will i have to pay for them? (going to have to sell some other shares to get the funds so i would like to sell them as late as possible)

Also, whats the process of payment for the new shares?

Thanks in advance
