Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We maintain our cash and cash equivalents with high-credit quality financial institutions. At
April 30, 2020,
we had cash and cash equivalent balances in excess of federally insured limits in the amount of approximately
$12.5
million.
 
For the
three
months ending
April 30, 2020,
two
customers, both distributors, accounted for approximately
11%
and
17%
of net sales. These same
two
distributors accounted for
11%
and
14%,
respectively, of net sales for the
six
months ending
April 30, 2020,
while in the same
six
-month period another customer, a wireless carrier, accounted for
11%
of net sales. The
two
distributors had accounts receivable balances that accounted for
14%
and
19%,
respectively, of the total net accounts receivable balance at
April 30, 2020.
For the
three
months ending
April 30, 2019,
one
of the aforementioned distributors and the wireless carrier accounted for approximately
28%
and
14%,
respectively, of net sales. This same distributor and a different wireless carrier accounted for approximately
32%
and
10%,
respectively, of net sales for the
six
months ending
April 30, 2019.
At
April 30, 2019,
the
two
wireless carrier customers had accounts receivable balances that accounted for approximately
10%
and
21%
of the total net accounts receivable balance, while the
two
distributors accounted for
18%
and
15%
of the total net accounts receivable balance. Although these customers have been on-going major customers of the Company, the written agreements with these customers do
not
have any minimum purchase obligations and they could stop buying our products at any time and for any reason. A reduction, delay or cancellation of orders from these customers or the loss of these customers could significantly reduce our future revenues and profits.
