|Income Tax Disclosure [Abstract]|
At September 30, 2017, we had $4.7 of deferred tax assets related to U.S. federal and state net operating losses and tax credit carryforwards, which will begin to expire in 2018, and $39.0 of deferred tax assets related to foreign net operating loss carryforwards, which will begin to expire in 2018. Deferred tax assets as of September 30, 2017, were reduced by a valuation allowance of $3.1 relating to foreign net operating loss carryforwards and foreign tax credit carryforwards. At September 30, 2017 and 2016, we had $18.3 and $16.6 of current income tax payable classified as other current liabilities on our balance sheets.
We establish a valuation allowance for deferred tax assets when it is determined that the amount of expected future taxable income is not likely to support the use of the deduction or credit.
As of September 30, 2017 and 2016, U.S. federal and state income taxes have not been provided on accumulated undistributed earnings of substantially all our foreign subsidiaries, as these earnings were considered permanently reinvested. However, as of September 30, 2017, $4.0 of deferred tax liability on unremitted earnings of foreign subsidiaries was recognized, representing the assumed tax on the distribution of such earnings among certain of our foreign subsidiaries. The total permanently reinvested earnings were $241.2 and $172.7 for 2017 and 2016. These amounts represent book earnings translated at historical rates. It is not practicable to estimate the tax liabilities that would be incurred upon full repatriation of undistributed earnings due to foreign tax credit limitation uncertainty and uncertainty on applicable withholding tax rate on certain foreign to foreign distributions.
A reconciliation of the unrecognized tax benefits is as follows:
The gross unrecognized tax benefit included $9.9 and $7.7 at September 30, 2017 and 2016, which, if recognized, would impact the effective tax rate in future periods.
We recognize accrued interest and penalties related to unrecognized tax benefits as income tax expense. During 2017 and 2016, we recognized $0.7 in additional interest and penalties. Excluded from the reconciliation were $1.3 and $1.3 of accrued interest and penalties at September 30, 2017 and 2016.
We operate in multiple income tax jurisdictions both inside and outside the U.S. and are currently under examination in various federal, state, and foreign jurisdictions. Specifically, we are currently under examination in the U.S. for 2016 and under examination in Germany for 2009 through 2013. In addition, there are other ongoing audits in various stages of completion in several state and foreign jurisdictions.
It is possible that the liability associated with the unrecognized tax benefits will increase or decrease within the next 12 months. These changes may be the result of ongoing audits or the expiration of statutes of limitations and could range up to $1.0 based on current estimates. Audit outcomes and the timing of audit settlements are subject to significant uncertainty. Although we believe that adequate provision has been made for such issues, it is possible that their ultimate resolution could affect our earnings. Conversely, if these issues are resolved favorably in the future, the related provision would be reduced and yield a positive impact on earnings. We do not expect that the outcome of these audits will significantly impact the financial statements.
The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
