the combined amount of accrued interest and penalties related to tax positions taken on our tax returns were approximately $ 24.6 million and $ 23.6 million for fiscal 2018 and 2017 , respectively . these amounts were included in long-term income taxes payable in their respective years . we file income tax returns in the united states on a federal basis and in many u.s . state and foreign jurisdictions . we are subject to the continual examination of our income tax returns by the irs and other domestic and foreign tax authorities . our major tax jurisdictions are ireland , california and the united states . for ireland , california and the united states , the earliest fiscal years open for examination are 2008 , 2014 and 2015 , respectively . we regularly assess the likelihood of outcomes resulting from these examinations to determine the adequacy of our provision for income taxes and have reserved for potential adjustments that may result from these examinations . we believe such estimates to be reasonable ; however , there can be no assurance that the final determination of any of these examinations will not have an adverse effect on our operating results and financial position . the timing of the resolution of income tax examinations is highly uncertain as are the amounts and timing of tax payments that are part of any audit settlement process . these events could cause large fluctuations in the balance of short-term and long- term assets , liabilities and income taxes payable . we believe that within the next 12 months , it is reasonably possible that either certain audits will conclude or statutes of limitations on certain income tax examination periods will expire , or both . given the uncertainties described above , we can only determine a range of estimated potential effect in underlying unrecognized tax benefits ranging from $ 0 to approximately $ 45 million. .
