We write off accounts receivable against the allowance when we determine a balance is uncollectible and no longer actively pursue collection of the receivable.

This write off had no impact on Accounts Receivable in fiscal 2018, as we had recorded a full allowance against our accounts receivable, net of deferred revenue, from the bankrupt distributor group in fiscal 2016, 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 fiscal year.
