text: The net change in the total valuation allowance for the fiscal years ended September 30, 2019 and 2018 was an increase of $0.5 million and an increase of $0.4 million, respectively. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. The Company considers projected future taxable income and planning strategies in making this assessment. Based on the level of historical operating results and the projections for future taxable income, the Company has determined that it is more likely than not that the deferred tax assets may be realized for all deferred tax assets with the exception of the net foreign deferred tax assets at Mitek Systems B.V.
