Warren Buffett's investment plan for his family

Put your money in index funds and move on, he told them. Seriously, you'll do better. In fact, he said, that's what I plan to do with my own money once I am gone.

Here's the quote, from page 20 of his most recent annual letter to Berkshire shareholders, dated Feb. 28. After all of his Berkshire shares are distributed to charity, take the cash, Buffett says, and just buy index funds:

My advice to the trustee couldn't be more simple: Put 10% of the cash in short-term government bonds and 90% in a very low-cost S&P 500 index fund. (I suggest Vanguard's.) I believe the trust's long-term results from this policy will be superior to those attained by most investors — whether pension funds, institutions or individuals — who employ high-fee managers.

so that what I will do for my registered accounts.
