A group said it might buy more Viacom shares.

A partnership led by top JMB Realty executives told the SEC that it has changed its decision not to add to its 11.69% stake in New York-based Viacom International. The partnership no longer claims that it is holding the shares “for investment purposes” as declared in a December filing. In addition, the partnership disclosed that it has exercised certain options to increase its holdings to nearly 2.37 million shares, about 11.78%, and might buy more.
