Promotional Costs [Abstract]
Promotional Costs	Promotional Costs The Company frequently makes promotional offers to members of its independent sales force to encourage them to fulfill specific goals or targets for other activities, ancillary to the Company's business, but considered separate and distinct services from sales, which are measured by defined group/team sales levels, addition of new sales force members or other business-critical functions. The awards offered are in the form of product awards, special prizes or trips. The Company accrues for the costs of these awards during the period over which the sales force qualifies for the award and reports these costs primarily as a component of DS&A expense. These accruals require estimates as to the cost of the awards, based upon estimates of achievement and actual cost to be incurred. During the qualification period, actual results are monitored, and changes to the original estimates are made when known. Promotional and other sales force compensation expenses included in DS&A expense totaled $78.6 million and $88.4 million for the first quarters of 2019 and 2018, respectively.
