A stock split-up occurs when a company separates into two (or more) parts and distributes the stock of the various parts to its shareholders. This is different from a split-off because in a split-up the stock of the original parent corporation you previously owned no longer exists. The original company goes away when stock is issued in two (or more) new companies. In comparison, in a split-off the previous corporation continues in existence. This is more fully explained on theStock Split-Uppage.
