Date of cessation of the all-resident/truncated enterprise group. Cessation of a group means either death of the group (dissolution of the links of control between the units belonging to the group), or (more commonly) other cessation date by merger with or take-over by another group, or break-up, split-off, or restructure into two or more groups. The death of an enterprise group is the cessation of all control links, direct or indirect, between the legal units of which the enterprise group consists. The legal units become independent again or cease to exist. No other enterprise group is involved.
