All domestic tax arises under the Irish tax jurisdiction. There is no direct relationship between the provision for income taxes and income or loss before income taxes for companies availing of the tonnage tax election in Ireland because Ireland operates a tonnage taxation regime which computes Irish corporation tax by reference to the weight of the ships rather than accounting profits. Accordingly, a reconciliation between the income tax expense and the income tax calculated based on net income at the Irish statutory rate, has not been presented herein as it would not provide additional useful information to users of the consolidated financial statements. All current elections are valid until a minimum of December 31, 2023. All tax years are open to audit by tax authorities. Reconciliation of deferred tax asset:

In the year ended December 31, 2012 Ardmore established a valuation allowance against deferred tax assets because Ardmore believed it was more likely than not that the full amount of the deferred tax assets generated primarily by non-tonnage trading losses would not be realized through the generation of taxable income in future periods.
