CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS

CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS

Financial instruments that potentially subject us 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 December 31, 2017 and March 31, 2017, 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 nine months ended December 31, 2017, no direct customers or indirect channel partners accounted for more than 10% of the Company's total revenue. During the three and nine months endedDecember 31, 2016, one direct customer, Verizon, accounted for more than 10% of the Company's total revenue, while no indirect channel partners accounted for more than 10% of 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 $3.1 million and $3.6 million at December 31, 2017 and March 31, 2017, 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.
