This is interesting! Shoddy writing int he Fortune piece though.

"The amount handed over [to charity], though, is not likely to be $1 million, because of changes that Buffett and Protégé made in the wager a couple of years ago"

One paragraph later:

"Buffett also issued a guarantee: He will pay the winning charity $1 million if the Berkshire stock bought isn’t worth that much at the bet’s end."

Nitpicky I know, but it sounds like the winning charity is guaranteed $1 million.

Read a few more lines down and they state that the amount will most likely be more than $1 million, thus keeping the previous two quotes consistent.
