Risks and Uncertainties [Abstract]
Concentrations of Risk	Concentrations of Risk Our revenues are concentrated in the area of OTC Healthcare. We sell our products to mass merchandisers and drug, food, dollar, convenience and club stores and e-commerce channels. During the three and six months ended September 30, 2019, approximately 42.6% and 43.3%, respectively, of our gross revenues were derived from our five top selling brands. During the three and six months ended September 30, 2018, approximately 44.7% and 43.5%, respectively, of our gross revenues were derived from our five top selling brands. One customer, Walmart accounted for more than 10% of our gross revenues for each of the periods presented. Walmart accounted for approximately 22.9% and 23.5%, respectively, of our gross revenues for the three and six months ended September 30, 2019. Walmart accounted for approximately 23.6% and 24.1%, respectively, of our gross revenues for the three and six months ended September 30, 2018. The gross revenues for Walmart are included in our North American OTC Healthcare segment and Household Cleaning segment (prior to the sale of our Household Cleaning segment on July 2, 2018). Our product distribution in the United States is managed by a third party through one primary distribution center near St. Louis, Missouri. On May 13, 2019, we entered into an agreement with a second third party logistics provider for a warehouse, and we are in the process of transitioning to this facility, which is managed by a new logistics provider. In addition, we operate one manufacturing facility for certain of our products located in Lynchburg, Virginia. A serious disruption, caused by performance or contractual issues with a third party distribution manager or by natural disaster, such as earthquake, flood, or fire, could damage our inventory and/or materially impair our ability to distribute our products to customers in a timely manner or at a reasonable cost. Any disruption as a result of business integration, transition of our distribution center to the new third party manager or new location, or third party performance at our distribution centers could result in increased costs, expense and/or shipping times, and could cause us to incur customer fees and penalties. In addition, any serious disruption to our Lynchburg manufacturing facility could materially impair our ability to manufacture many of the products associated with our acquisition of C.B. Fleet Company, Inc. ("Fleet"), which would also limit our ability to provide those products to customers in a timely manner or at a reasonable cost. We could also incur significantly higher costs and experience longer lead times if we need to replace our distribution centers, the third party distribution managers or the manufacturing facility. As a result, any serious disruption could have a material adverse effect on our business, financial condition and results of operations. At September 30, 2019, we had relationships with 113 third party manufacturers. Of those, we had long-term contracts with 30 manufacturers that produced items that accounted for approximately 66.4% of gross sales for the six months ended September 30, 2019. At September 30, 2018, we had relationships with 110 third party manufacturers. Of those, we had long-term contracts with 34 manufacturers that produced items that accounted for approximately 60.0% of gross sales for the six months ended September 30, 2018. The fact that we do not have long-term contracts with certain manufacturers means that they could cease manufacturing our products at any time and for any reason or initiate arbitrary and costly price increases, which could have a material adverse effect on our business and results of operations. Although we are continually in the process of negotiating long-term contracts with certain key manufacturers, we may not be able to reach a timely agreement, which could have a material adverse effect on our business and results of operations.
