Two hundred of the employees are top-level executives and managers, sixty of whom are concurrently employed by two or more of the corporations during a calendar quarter. Six thousand of the employees are skilled artisans, all of whom are concurrently employed by two or more of the corporations during the calendar year. The four corporations arrange for Z to disburse remuneration to the sixty executives who are concurrently employed by two or more of the corporations. W and X arrange for X to disburse remuneration to the artisans who are concurrently employed by W and X.
