Franking credit refunds PBO estimates in doubt, page-55

Now, ask yourself, why would the other 75 percent , be ignored?

Don't know but in their original document they did state that estimates were of low confidence over the longer term as changes will be amplified.

I'll lose some franking credit refunds but will probably retain the associated shares.
I might even buy more if there is a buying opportunity as I don't have all my eggs in one basket, as it were.
