Cantor Fitzgerald does have a list of some 320 employees in New York City that have been reported as safe, however, none of those employees are believed to have been in their offices on the 101st, 103rd, 104th and 105th floors of the tower. Cantor Fitzgerald employed approximately 1000 people on those four floors.
