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. The amounts of accounts receivable written off were insignificant for all periods presented. Bad debt expense was negligible for fiscal 2017. During fiscal 2016, we recorded a full allowance on our accounts receivable, net of deferred revenue, from a bankrupt distributor group resulting in an increase in allowance for doubtful accounts of </font><font style="font-family:Arial;font-size:9pt;">$9.0 million</font><font style="font-family:Arial;font-size:9pt;"> and bad debt expense of </font><font style="font-family:Arial;font-size:9pt;">$7.5 million</font><font style="font-family:Arial;font-size:9pt;"> in that year.</font></div><div style="line-height:120%;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.
