Splitting Damage/Counters/etc.

[Zhalfirin]

I am 99% sure this is how it works, but I just wanted confirmation:

1) If some spell/ability divides something (damage/counters/whatever) among a set of targeted permanents, the controller of the spell/ability must announce that division when the spell/ability goes on the stack, correct?

2) On a side note, if the spell/ability is NOT targeted, then no division is announced, correct?

1.  Correct, as with Fire or Contagion.  The decision is made upon announcement.

2.  Correct, as with Forgotten Ancient.  Decisions here are made upon resolution.
