Carlos Slim Adds to Stake in Times Company

Carlos Slim Helú, the Mexican billionaire who is by some accounts the world’s richest man, has added to his holdings in The New York Times Company.

In a regulatory filing, Slim and members of his family said they had bought additional shares in the company, raising their ownership stake to just over 7 percent. Previously the family owned just under 7 percent. Slim and his family hold warrants to buy nearly 16 million more shares, which would bring their holdings to 16 percent should they choose to execute them. The warrants expire in 2015. The Times Company recently repaid Mr. Slim a $250 million loan, plus 14 percent interest.
