CONCENTRATIONS OF CREDIT RISK AND MAJOR CUSTOMERS

10. CONCENTRATIONS OF CREDIT RISK AND MAJOR CUSTOMERS

The Group's financial instruments that are exposed to concentrations of credit risk consist primarily of its cash and cash equivalents and trade receivables.

The Group's cash and cash equivalents are high-quality deposits placed with banking institutions with high credit ratings. This investment policy limits the Group's exposure to concentrations of credit risk.

The trade receivable balances largely represent amounts due from the Group's principal customers who are generally international organizations with high credit ratings. Letters of credit are the principal security obtained to support lines of credit or negotiated contracts from a customer. As a consequence, related credit risk are limited.

Accounts receivable from the three customers with the largest receivable balances as of March 31, 2016 and 2017 are as follows:

		Percentage of accounts receivable
		2016				2017
		%				%
Customer A			45.3				47.9
Customer B			12.9				13.0
Customer C			11.0				12.0
Three largest receivable balances			69.2				72.9

Details of the movements of the allowances for doubtful account are as follows:

		Year ended March 31,
		2015				2016				2017
		$				$				$
At beginning of year			6				6				6
Allowance for the year			-				-				60
At end of year			6				6				66

A substantial percentage of the Group's sales are made to four customers and are typically on an open account basis. Customers accounting for 10% or more of total net sales in any of the years ended March 31, 2015, 2016 and 2017 are as follows:

		Year ended March 31,
