How are IRAs being changed?

7. Thinking about this and it troubles me

that the financial advisor's letter didn't spell out exactly why and how these accounts are different. It's the sort of thing that the new regulations require.

It is possible that there is some other reason for this grandfathering and new accounts than what I found in the article I linked above.

I'd still call the adviser and put him on the spot. I'd ask are there any other differences between account types.
