Slim. Or anyone else. A number of lists show 4 different vanguard funds totaling about 4.430,000 shares. And they show another vanguard unit with approximately the same amount. Does vanguard own 4.4 million or 8.8 million. On dude abides old list from morningstar it shows 4 vanguard funds under the funds tab. And another vanguard entry under institutions for about 4.4 million. So do they 4.4 or 8.8?
