Attention investment-math nerds — clear something up for us? Reading through the SEC filing for all the Youtubers preparing to sell their Google stock, a reader asks:

Strange that the heading "All Other Sequoia Capital XI, L.P. Investors and Their Transferees who Beneficially Own, in the Aggregate, Less than 1% of the Class A common stock" refers to some 409,000 shares, which would represent some 12% of the total, not less than 1% as described. In any case, that's quite a lot of ownership that's going unreported while many people who own much smaller fractions of the shares are listed clear as day.

Thoughts? Thrill us with your acumen.
