The Company sourced approximately 24% of its electrotherapy products from one contract manufacturer during the three months ended March 31, 2013. Management believes that its relationships with suppliers are strong; however, if necessary these relationships can be replaced. 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 a private health insurance carrier at March 31, 2013 that made up approximately 16% of the net accounts receivable balance. The same private health insurance carrier made up approximately 22% of net accounts receivable at December 31, 2012.
