14. 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, restricted cash 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, 2012 and 2013 are as follows:

 

    Percentage of
accounts receivable		  
    2012     2013  
      %       %  
                 
Customer A     19.6       36.6  
Customer B     44.4       12.4  
Customer C     17.3       13.2  
                 
Three largest receivable balances     81.3       62.2
