We purchase a significant amount of our 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 generally pass to us upon shipment from the manufacturers’ plant or warehouse. For the three months ended May 31, 2020, four of our suppliers accounted for approximately 61% of our total inventory purchases and for the three months ended May 31, 2019, two of our suppliers accounted for approximately 47% of total inventory purchases. As identified below, some of these manufacturers accounted for more than 10% of our accounts payable as follows (rounded):

	May 31,			February 29,
	2020			2020
Accounts payable:
Supplier A		17	%		11	%
Supplier B		13	%		11	%

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.
