A reconciliation using the Netherlands statutory rate was not provided as there are no significant operations in the Netherlands. Deferred tax assets and liabilities are recorded for the anticipated future tax effects of temporary differences between the financial statement basis and tax basis of our assets and liabilities using the applicable tax rates in effect at year-end. A valuation allowance is recorded when it is not more likely than not that some or all of the benefit from the deferred tax asset will be realized. Significant components of deferred tax assets and liabilities are as follows (in thousands):

Undistributed earnings of certain of our foreign subsidiaries amounted to approximately $500.0 million at December 31, 2015. It is our intention to permanently reinvest undistributed earnings and profits from the subsidiaries of the consolidated companies’ operations that have been generated through December 31, 2015 and future plans do not demonstrate a need to repatriate the foreign amounts to fund parent company activity. As of December 31, 2015 and 2014, we have total gross unrecognized tax benefits of $0.1 million and $0.3 million, respectively. Substantially all of the uncertain tax positions, if recognized in the future, would impact our effective tax rate. We have elected to classify interest and penalties incurred on income taxes as income tax expense. We file income tax returns in various international tax jurisdictions. As of December 31, 2015, the tax years 2009 through 2015 remain open to examination in the major foreign taxing jurisdictions to which we are subject. We are currently under audit by the Internal Revenue Service for the tax period ending June 30, 2014. We do not expect any material adjustments resulting from this audit.
