It's widely believed that there are about 34M shares in the pool. The Gang of Four donated their dividends shares, not their original shares. I divided 34M by 21 and come up with about 1.6M shares still owned by the group.

Multiply by $3 and their shares collectively are worth about $5M. I have no idea if that's an accurate figure, but I hope they are still in the black, even with the generous donation of their dividend shares.
