[1] | In the third quarter of fiscal year 2019, the Company recorded an allowance of $8.7 million for bad debt expense related to a large former education client who entered federal receivership in January 2019. In the second quarter of fiscal year 2021, the Company believes that the likelihood of collection was no longer probable, therefore has determined to write off the receivable against this allowance, with no net impact to the Company’s consolidated statements of operations.
