Comcast Corp. shareholders will vote on Dec. 10 whether to reclassify 347 million nonvoting K shares as regular voting common stock, while preserving the Roberts family's 33 percent voting control of the cable and Internet giant. The special shareholders meeting is scheduled for 8:30 a.m. at the Top of the Tower at 1717 Arch Street.

This vote is for shareholders of record on Oct. 20 and they are expected to approve the measure.

Comcast CEO Brian Roberts holds the 33 percent voting control of the Philadelpiha company through the super-voting class B shares and will retain class B-related rights.
