They should know where they stand on tax from WD and their position on CCP so they will have those franking credits available.
There is no reason they can't distribute this money as soon as it is available but they are more likely to wait for the ruling to make a single distribution rather than drib and drab it.

When the qtrly comes out following the payment of CCP there should be a liability noted in the qtrly. It is probable that the tax won't actually be payable to the ATO until around Dec/Jan anyway.
