It’s not really an MM question, it’s a more general point about retrospective amendment of earnings. A lot of fluctuations can be massaged away in an updated average without going back, but this seems like a pretty clear cut change on a date you can identify and it would be difficult to avoid picking this up retrospectively, MM or no MM. But, as this is an MM case, it does mean that all the numbers on “migration day” need to be revisited for the purpose of both the HB run on and transitional protection.
