Deferred tax assets are recognized on the basis that sufficient future profits will be available against which they may be utilized.

The Company recognized all deferred tax assets and liabilities at March 31, 2020, 2019 and 2018, with the exception of certain deductible temporary differences where near term recovery is not probable and therefore have not been recognized in the Consolidated Balance Sheet, of approximately €132m (2019: €nil; 2018: €nil). These deductible temporary differences are not subject to expiry based on current tax legislation and are subject to annual review. No deferred tax has been provided for un-remitted earnings of overseas subsidiaries. No temporary differences arise on the carrying value of the tax base of subsidiary companies as the Company’s trading subsidiaries are resident in countries with which Ireland has concluded double taxation agreements.

The Company had applied IFRIC 23 ‘Uncertainty over Income Tax Treatment’ for the first time for the year ended March 31, 2020. Adoption of IFRIC 23 did not have an impact on the consolidated financial statements as the Group's existing accounting policy for uncertain income tax treatments is consistent with the requirements of IFRIC 23.
