The estimated annual effective income tax rate for the current fiscal year is primarily driven by the valuation allowance, with a lesser impact attributable to federal research tax credits and the benefit of certain state tax losses, offset by income tax expenses in profitable foreign jurisdictions. Realization of the Company's net deferred tax assets is dependent upon its generation of sufficient taxable income of the proper character in future years in appropriate tax jurisdictions to obtain benefit from the reversal of temporary differences and net operating loss carryforwards. In the quarter ended September 30, 2019, the Company released a portion of its valuation allowance in connection with deferred tax liabilities associated with DPM acquired intangibles (see Note 5). As of September 30, 2019, the Company continues to maintain a full valuation allowance on its net deferred tax assets except in certain foreign jurisdictions.
