CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS

CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS

Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of investments, trade accounts receivable and accounts payable. The Company's cash, cash equivalents, and marketable securities are placed with financial institutions with high credit standings.

At September 30, 2018 the Company had one direct customer, Verizon, who accounted for more than 10% of the accounts receivable balance, while no indirect channel partner accounted for more than 10% of the accounts receivable balance. At March 31, 2018, the Company had no direct customers or indirect channel partners which accounted for more than 10% of the accounts receivable balance.

During the three and six months ended September 30, 2018 and September 30, 2017, no direct customers or indirect channel partners accounted for more than 10% of the Company's total revenue.

As disclosed parenthetically within the Company's consolidated balance sheet, the Company has receivables from related parties included within prepaid expenses and other current assets that represent a concentration of credit risk of $1.5 million and $3.2 million at September 30, 2018 and March 31, 2018, respectively.

Historically, the Company has not experienced any significant failure of its customers' ability to meet their payment obligations nor does the Company anticipate material non-performance by its customers in the future; accordingly, the Company does not require collateral from its customers. However, if the Company's assumptions are incorrect, there could be an adverse impact on its allowance for doubtful accounts.
