Significant Customer Concentration

A credit concentration may exist if customers are involved in similar industries, economic sectors, and geographic regions. Our retail distributors operate in similar economic sectors but diverse domestic geographic regions. The loss of a significant retail distributor could have a material adverse effect upon our card sales, profitability, and revenue growth.

Revenues derived from our products sold at retail distributors constituting greater than 10% of our total operating revenues were as follows:



	Three Months Ended June 30,		Six Months Ended June 30,
	2015	2014	2015	2014
Walmart	48%	54%	42%	58%
