Please answer the given financial question based on the context.
Context: the valuation allowance as of 30 september 2016 of $ 155.2 primarily related to the tax benefit on the federal capital loss carryforward of $ 48.0 , tax benefit of foreign loss carryforwards of $ 37.7 , and capital assets of $ 58.0 that were generated from the loss recorded on the exit from the energy-from-waste business in 2016 . if events warrant the reversal of the valuation allowance , it would result in a reduction of tax expense . we believe it is more likely than not that future earnings and reversal of deferred tax liabilities will be sufficient to utilize our deferred tax assets , net of existing valuation allowance , at 30 september 2016 . the deferred tax liability associated with unremitted earnings of foreign entities decreased in part due to the dividend to repatriate cash from a foreign subsidiary in south korea . this amount was also impacted by ongoing activity including earnings , dividend payments , tax credit adjustments , and currency translation impacting the undistributed earnings of our foreign subsidiaries and corporate joint ventures which are not considered to be indefinitely reinvested outside of the u.s . we record u.s . income taxes on the undistributed earnings of our foreign subsidiaries and corporate joint ventures unless those earnings are indefinitely reinvested outside of the u.s . these cumulative undistributed earnings that are considered to be indefinitely reinvested in foreign subsidiaries and corporate joint ventures are included in retained earnings on the consolidated balance sheets and amounted to $ 6300.9 as of 30 september 2016 . an estimated $ 1467.8 in u.s . income and foreign withholding taxes would be due if these earnings were remitted as dividends after payment of all deferred taxes . a reconciliation of the beginning and ending amount of the unrecognized tax benefits is as follows: .
|unrecognized tax benefits|2016|2015|2014|
|balance at beginning of year|$ 97.5|$ 108.7|$ 124.3|
|additions for tax positions of the current year|15.0|6.9|8.1|
|additions for tax positions of prior years|3.8|7.5|4.9|
|reductions for tax positions of prior years|-.3 ( .3 )|-7.9 ( 7.9 )|-14.6 ( 14.6 )|
|settlements|-5.6 ( 5.6 )|-.6 ( .6 )|2014|
|statute of limitations expiration|-3.0 ( 3.0 )|-11.2 ( 11.2 )|-14.0 ( 14.0 )|
|foreign currency translation|-.5 ( .5 )|-5.9 ( 5.9 )|2014|
|balance at end of year|$ 106.9|$ 97.5|$ 108.7|
at 30 september 2016 and 2015 , we had $ 106.9 and $ 97.5 of unrecognized tax benefits , excluding interest and penalties , of which $ 64.5 and $ 62.5 , respectively , would impact the effective tax rate if recognized . interest and penalties related to unrecognized tax benefits are recorded as a component of income tax expense and totaled $ 2.3 in 2016 , $ ( 1.8 ) in 2015 , and $ 1.2 in 2014 . our accrued balance for interest and penalties was $ 9.8 and $ 7.5 as of 30 september 2016 and 2015 , respectively. .
