We regularly review our allowance for doubtful accounts and the aging of our accounts receivable.</font></div><div style="line-height:120%;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:9pt;"><font style="font-family:Arial;font-size:9pt;">Accounts receivable do not bear interest and are shown net of allowances for doubtful accounts of </font><font style="font-family:Arial;font-size:9pt;">$0.4 million</font><font style="font-family:Arial;font-size:9pt;"> and </font><font style="font-family:Arial;font-size:9pt;">$9.4 million</font><font style="font-family:Arial;font-size:9pt;"> at </font><font style="font-family:Arial;font-size:9pt;">September 29, 2018</font><font style="font-family:Arial;font-size:9pt;"> and </font><font style="font-family:Arial;font-size:9pt;">December 30, 2017</font><font style="font-family:Arial;font-size:9pt;">, respectively. The allowance for doubtful accounts reflects our best estimate of probable losses inherent in the accounts receivable balance. We determine the allowance based on assessment of known troubled accounts, analysis of the aging of our accounts receivable, historical experience, management judgment, and other currently available evidence. We write off accounts receivable against the allowance when we determine a balance is uncollectible and no longer actively pursue collection of the receivable. During the third quarter of fiscal 2018, we wrote off </font><font style="font-family:Arial;font-size:9pt;">$9.0 million</font><font style="font-family:Arial;font-size:9pt;"> of accounts receivable from a bankrupt distributor group. We had recorded a full allowance on this amount in the third quarter of fiscal 2016, so there was no impact on Accounts Receivable, net in the current period. Bad debt expense was negligible for all periods presented.</font></div><div style="line-height:120%;text-align:left;font-size:9pt;"><font style="font-family:Arial;font-size:9pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:9pt;"><font style="font-family:Arial;font-size:9pt;">We place our investments primarily through one financial institution and mitigate the concentration of credit risk by limiting the maximum portion of the investment portfolio which may be invested in any one instrument. Our investment policy defines approved credit ratings for investment securities. Investments on-hand in marketable securities consisted primarily of money market instruments, “AA” or better corporate notes and bonds and commercial paper, and U.S. government agency obligations. See "Note 4 - Marketable Securities" for a discussion of the liquidity attributes of our marketable securities.</font></div><div style="line-height:120%;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:9pt;"><font style="font-family:Arial;font-size:9pt;">We rely on a limited number of foundries for our wafer purchases, including Fujitsu Limited, Seiko Epson Corporation, Taiwan Semiconductor Manufacturing Company, Ltd, and United Microelectronics Corporation. We seek to mitigate the concentration of supply risk by establishing, maintaining and managing multiple foundry relationships; however, certain of our products are sourced from a single foundry and changing from one foundry to another can have a significant cost, among other factors.</font></div><div style="line-height:120%;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;"><br clear="none"/></font></div></div>
