IVZ Share Price, page-20290

Sorry, what? Is that how it works?

Granted I haven't looked into it into much detail, but I always thought it worked like this:

I have 10 shares which ive held for 12 months and then buy an additional 5 today.

I sell 5 shares a week later - Those 5 will automatically have CGD applied to them as I have 10 in the kitty with CGD. And the remaining 10 will be half CGD half not

What I'm saying is, I didn't know you could pick and choose which shares you are selling? I'm guessing in light of what I'm understanding - The time you will "pick and choose" will be at tax time?
