Investment policies have been implemented that limit investments to investment-grade securities.</font></div><div style="line-height:120%;padding-top:12px;text-indent:48px;font-size:9pt;"><font style="font-family:Arial;font-size:9pt;">The risk with respect to accounts receivable is mitigated by ongoing credit evaluations that the Company performs on its customers. As the Company continues to expand its sales internationally, it may experience increased levels of customer credit risk associated with those regions. Collateral is generally not required for accounts receivable but may be used in the future to mitigate credit risk associated with customers located in certain geographical regions.</font></div><div style="line-height:120%;padding-top:12px;text-indent:48px;font-size:9pt;"><font style="font-family:Arial;font-size:9pt;">As of December 29, 2018, </font><font style="font-family:Arial;font-size:9pt;">no</font><font style="font-family:Arial;font-size:9pt;"> customers accounted for over 10% of the Company's net accounts receivable balance. As of December 30, 2017, </font><font style="font-family:Arial;font-size:9pt;">two</font><font style="font-family:Arial;font-size:9pt;"> customers accounted for over 10% of the Company's net accounts receivable balance. One customer accounted for approximately </font><font style="font-family:Arial;font-size:9pt;">11%</font><font style="font-family:Arial;font-size:9pt;"> of the Company's net accounts receivable balance, and another customer, which completed a merger in late 2017, was a combination of two of the Company's historically larger customers, accounted for approximately </font><font style="font-family:Arial;font-size:9pt;">16%</font><font style="font-family:Arial;font-size:9pt;"> of the Company's net accounts receivable balance.</font></div><div style="line-height:120%;padding-top:12px;text-indent:48px;font-size:9pt;"><font style="font-family:Arial;font-size:9pt;">To date, a few of the Company’s customers have accounted for a significant portion of its revenue. One customer accounted for approximately </font><font style="font-family:Arial;font-size:9pt;">15%</font><font style="font-family:Arial;font-size:9pt;"> of the Company's revenue in 2018. </font><font style="font-family:Arial;font-size:9pt;">One</font><font style="font-family:Arial;font-size:9pt;"> other customer, which completed a merger in late 2017 as mentioned above, was a combination of two of the Company's historically larger customers who merged in 2017 and accounted for approximately </font><font style="font-family:Arial;font-size:9pt;">13%</font><font style="font-family:Arial;font-size:9pt;"> and </font><font style="font-family:Arial;font-size:9pt;">18%</font><font style="font-family:Arial;font-size:9pt;"> of the Company's revenue in 2018 and 2017, respectively. These two historically larger customers each individually accounted for approximately </font><font style="font-family:Arial;font-size:9pt;">16%</font><font style="font-family:Arial;font-size:9pt;"> and </font><font style="font-family:Arial;font-size:9pt;">8%</font><font style="font-family:Arial;font-size:9pt;"> of the Company's revenue in 2016, respectively. No other customers accounted for over 10% of the Company's revenue for 2017 or 2016.</font></div><div style="line-height:120%;padding-top:12px;text-indent:48px;font-size:9pt;"><font style="font-family:Arial;font-size:9pt;">The Company depends on sole source or limited source suppliers for several key components and raw materials. The Company generally purchases these sole source or limited source components and raw materials through standard purchase orders and does not have long-term contracts with many of these limited-source suppliers. While the Company seeks to maintain sufficient reserve stock of such components and raw materials, the Company’s business and results of operations could be adversely affected if any of its sole source or limited source suppliers suffer from capacity constraints, lower than expected yields, deployment delays, work stoppages or any other reduction or disruption in output.</font></div></div>

These accounting principles require the Company to make certain estimates, assumptions and judgments that can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Significant estimates, assumptions and judgments made by management include revenue recognition, stock-based compensation, inventory valuation, accrued warranty, business combinations and accounting for income taxes. Other estimates, assumptions and judgments made by management include restructuring and other related costs, allowances for sales returns, allowances for doubtful accounts, pension, useful life of acquired intangibles and recoverability of property, plant and equipment, fair value measurement of the liability component of the convertible senior notes, non-marketable equity investments and derivative instruments. Management believes that the estimates, assumptions and judgments upon which they rely are reasonable based upon information available to them at the time that these estimates and judgments are made. To the extent there are material differences between these estimates and actual results, the Company’s consolidated financial statements will be affected.</font></div></div>
