two

most recent fiscal years:

	% of Revenue for Year Ended March 31
	2021		2020
Customer A		22%		24%
Customer B		15%		14%
Customer C	Less than 10%			10%

These customers accounted for

43%

of our accounts receivable as of

March 

31,

2021

and

43%

not

represent a significant credit risk based on past collection experience.
