Subject: Re: De-risk a bit?
That point should be now. For a few reasons. One, because they can make better use of the money now than in 20+ years when they are already fully established financially. You should be giving each kid (and their spouse), and your wife should be giving each kid (and their spouse) $19k a year.

Actually you can give them up to $15,000,000 (lifetime gift limit) right now tax free (twice that if from both you and your wife) and file an IRS Form 709. I think, but don't know, that the gift can be in the form of a transfer of Berkshire shares to them.
