We sell telematics products and services to large global enterprises in the industrial equipment, transportation and automotive market verticals. For the three months ended May 31, 2019 and 2018, we had one customer that represented approximately 14% and 12% of our total sales, respectively. The same customer represented approximately 14% of our total accounts receivable balance as of May 31, 2019 and February 28, 2019.

We purchase a significant amount of our product inventory from certain manufacturers or suppliers including components, assemblies and electronic manufacturing parts. These suppliers are located in Asia, including China. The inventory is purchased under standard supply agreements that outline the terms of the product delivery. The title and risk of loss of the product passes to us upon shipment from the manufacturers’ plant or warehouse. As identified below, some of these manufacturers accounted for more than 10% of our purchases and accounts payable as follows (rounded):

	Three Months Ended May 31,
	2019			2018
Inventory purchases:
Supplier A		34	%		28	%
Supplier B		13	%		21	%

	May 31,			February 28,
	2019			2019
Accounts payable:
Supplier A		21	%		30	%
Supplier B		12	%		18	%

We are currently reliant upon these suppliers for products. Although we believe that we can obtain products from other sources, the loss of a significant supplier could have a material impact on our financial condition and results of operations as the products that are being purchased may not be available on similar terms from another supplier.
