For the three months ended March 31, 2020, the Company sourced approximately 40% of the components for its electrotherapy products from two significant vendors (defined as supplying at least 10%). For the three months ended March 31, 2019 the company sourced approximately 57% of components from two significant vendors.

Management believes that its relationships with suppliers are good; however, if the relationships were to be replaced, there may be a short-term disruption to operations, a period of time in which products may not be available and additional expenses may be incurred.

The Company had receivables from two third-party payers at March 31, 2020 and December 31, 2019, that made up approximately 39% of the net accounts receivable balance.
