The Company believes that there is minimal credit risk associated with the investment of its cash and cash equivalents and short-term investments, due to the restrictions placed on the type of investment that can be entered into under the Company's investment policy. The Company's short-term investments consist of investment-grade securities, and the Company's cash and investments are held and managed by recognized financial institutions.</font></div><div style="line-height:120%;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company's customers are primarily distributors as well as retailers and broadband service providers who sell or distribute the products to a large group of end-users. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of the Company's customers to make required payments. The Company regularly performs credit evaluations of the Company's customers' financial condition and considers factors such as historical experience, credit quality, age of the accounts receivable balances, geographic or country-specific risks and current economic conditions that may affect customers' ability to pay. The Company does not require collateral from its customers. The Company secures credit insurance for certain customers in international and domestic markets.</font></div><div style="line-height:120%;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">As of </font><font style="font-family:inherit;font-size:10pt;">December 31, 2017</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">2016</font><font style="font-family:inherit;font-size:10pt;">, </font><font style="font-family:inherit;font-size:10pt;">Best Buy, Inc.</font><font style="font-family:inherit;font-size:10pt;"> and affiliates accounted for </font><font style="font-family:inherit;font-size:10pt;">35%</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">38%</font><font style="font-family:inherit;font-size:10pt;"> of the Company's total accounts receivable, respectively.

In the event of turbulence or the onset of a financial crisis in financial markets, the failure of additional counterparties cannot be ruled out.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div></div>
