CY2020	us-gaap	Use Of Estimates UseOfEstimates	Use of EstimatesThe preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect amounts in the consolidated financial statements and accompanying notes. For the year ended September 30, 2020, these estimates required the Company to make assumptions about the extent and duration of the COVID-19 pandemic and its impacts on the Company's results of operations. As there remains uncertainty associated with the COVID-19 pandemic, the Company will continue to update its assumptions as conditions change. Actual results could differ from those estimates.
