Income Tax Expense |
As part of the process of preparing our consolidated financial statements we are required to determine our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax expense together with assessing temporary differences resulting from recognition of items for income tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be recovered from taxable income during the carryback period or in the future; and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we must reflect this increase as an expense within the tax provision in the statement of operations. We do not provide for income taxes on undistributed earnings of foreign subsidiaries, as our current intention is to permanently reinvest these earnings. We recognize, measure, present and disclose in our financial statements uncertain tax positions that we have taken or expect to take on a tax return. We operate in multiple taxing jurisdictions, both within the United States and outside of the United States, and may be subject to audits from various tax authorities regarding transfer pricing, the deductibility of certain expenses, intercompany transactions, and other matters. Within specific countries, we may be subject to audit by various tax authorities operating within the country and may be subject to different statutes of limitation expiration dates. Management’s judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities, liabilities for uncertain tax positions, and any valuation allowance recorded against our net deferred tax assets. We will continue to monitor the realizability of our deferred tax assets and adjust the valuation allowance accordingly. Our policy is to classify interest and penalties related to unrecognized tax benefits as income tax expense. This policy has been consistently applied in all periods. Our 2013 income tax expense varies from the statutory rate mainly due to discrete items related to a research and development tax credit earned in 2012, but enacted into law in January 2013 and the recognition of uncertain tax positions as a result of the lapse in the statute of limitations, lower statutory rates from our foreign entities and certain permanent items. Our 2012 income tax expense varied from the statutory rate amounts mainly due to the inclusion of certain foreign entities with losses, from lower statutory rates at our foreign German entity, offset by certain permanent and discrete items. We have reviewed the tax positions taken, or to be taken, in our tax returns for all tax years currently open to examination by a taxing authority. As of September 30, 2013, the gross amount of unrecognized tax benefits exclusive of interest and penalties was $130,000. We remain subject to examination until the statute of limitations expires for each respective tax jurisdiction. The statute of limitations will be open with respect to these tax positions until 2017. A reconciliation of beginning and ending amount of our unrecognized tax benefits is as follows:
As of September 30, 2013, a summary of the tax years that remain subject to examination in our most significant tax jurisdictions is as follows:
