Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our income tax expense for the three months ended December 31, 2020 was $26 thousand, or 2.3% of pre-tax income, compared to income tax expense of $84 thousand, or 1.8% of pre-tax income, for the three months ended December 31, 2019. The effective income tax rate in each period differed from the federal statutory tax rate of 21% primarily as a result of changes in the valuation allowance and state taxes. The balance of the valuation allowance for our deferred tax assets was $17.4 million as of December 31, 2020 and September 30, 2020. As discussed in Note 13 on “Income Taxes” in our 2020 Annual Report on Form 10-K filed with the SEC on December 3, 2020, during the year ended September 30, 2020, we recorded an income tax refund of approximately $11.3 million as a result of certain provisions of the CARES Act, of which $7.1 million remained outstanding as of September 30, 2020. During the three months ended December 31, 2020, we received approximately $2.8 million in refunds, leaving $4.3 million as an income tax receivable recorded in “Receivable, net” on the condensed consolidated balance sheet as of December 31, 2020. We expect to receive the remaining $4.3 million subsequent to the filing of our consolidated tax return for our fiscal 2020 later this year. As of December 31, 2020, we continued to have a full valuation allowance against all deferred tax assets that rely upon future taxable income for their realization and will continue to evaluate our valuation allowance in future periods for any change in circumstances that causes a change in judgment about the realizability of the deferred tax assets. The amount of the deferred tax assets considered realizable, however, could be adjusted in future periods if estimates of future taxable income during the carryforward period are increased, if objective negative evidence in the form of cumulative losses is no longer present and if additional weight is given to subjective evidence such as our projections for growth.
