Ummm...correct me if I'm wrong here, but...
Haven't you just "exposed" the fact that an investment firm owns stock in a company?
In point of fact, several investment companies own New York Times shares--Class A shares that have little voting power. Of these, two (the Sulzbergers at 19 percent and T. Rowe Price at 15 percent) own more shares than Private Capital Management (9.34 percent).
The Ochs-Sulzberger family trust controls roughly 88% of the company's class B shares.
