Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended March 31, 2018, the Company recognized income tax expense of approximately $0.8 million, which included a discrete tax benefit of $0.2 million related principally to prior year tax reserve releases. For the three months ended March 31, 2017, the Company recognized income tax expense of approximately $0.5 million, which included a discrete tax benefit of $0.6 million related principally to prior year tax reserve releases. Excluding the discrete income tax items, the estimated effective tax rate for the three months ended March 31, 2018 was 291.8% compared to 38.8% for the three months ended March 31, 2017. The changes in the effective tax rate and tax expense between the periods resulted primarily from the reduction in the U.S. corporate tax rate following the enactment of the 2017 U.S. Tax Cut and Jobs Act along with changes in the mix of earnings in various geographic jurisdictions between the current year and the same period of last year. For the nine months ended March 31, 2018, the Company recognized an income tax expense of approximately $0.03 million, which included a discrete tax benefit of $2.7 million related to remeasuring the Company’s U.S. deferred tax assets and liabilities following enactment of the 2017 U.S. Tax Cut and Jobs Act in December 2017 and a discrete tax benefit of $0.2 million related principally to prior year tax reserve releases. For the nine months ended March 31, 2017, the Company recognized income tax expense of approximately $2.8 million, which included a discrete tax benefit of $0.6 million related principally to prior year tax reserve releases. Excluding the discrete income tax items, the estimated effective tax rate for the nine months ended March 31, 2018 was 35.5% compared to 36.6% for the nine months ended March 31, 2017. The changes in the effective tax rate and tax expense between the periods resulted primarily from the reduction in the U.S. corporate tax rate following the enactment of the 2017 U.S. Tax Cut and Jobs Act along with changes in the mix of earnings in various geographic jurisdictions between the current year and the same period of last year. During the quarter ended September 30, 2016, the Company contributed certain packaging equipment as required by the JV Agreement by transferring the legal titles of such equipment to the JV Company. As a result of the transfer, the Company reduced its deferred tax assets by $6.6 million and recorded a $6.6 million in prepaid tax asset, which was amortized to tax expense over the useful life of the assets. As of June 30, 2017, the prepaid tax asset was amortized down to $5.5 million, of which $1.1 million and $4.4 million were included in prepaid and other current assets and other long-term assets on the Company's balance sheet, respectively. On July 1, 2017, the Company adopted ASU 2016-16, Intra-Entity Transfers of Assets other than Inventory, which resulted in a de-recognition of a prepaid tax asset of $5.5 million related to the prior period intra-entity asset transfer with the JV Company, with an offsetting reduction to retained earnings. Because the JV Company has a full valuation allowance, there was no change to the Company’s net deferred tax assets. The Company files its income tax returns in the United States and in various foreign jurisdictions. The tax years 2002 to 2017 remain open to examination by U.S. federal and state tax authorities. The tax years 2010 to 2017 remain open to examination by foreign tax authorities. The Company's income tax returns are subject to examinations by the Internal Revenue Service and other tax authorities in various jurisdictions. In accordance with the guidance on the accounting for uncertainty in income taxes, the Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. These assessments can require considerable estimates and judgments. As of March 31, 2018, the gross amount of unrecognized tax benefits was approximately $6.7 million, of which $4.0 million, if recognized, would reduce the effective income tax rate in future periods. If the Company's estimate of income tax liabilities proves to be less than the ultimate assessment, then a further charge to expense would be required. If events occur and the payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the Company determines the liabilities are no longer necessary. The Company does not anticipate any material changes to its uncertain tax positions during the next twelve months. On July 27, 2015, in Altera Corp. v. Commissioner, the U.S. Tax Court issued an opinion related to the treatment of share-based compensation expense in an intercompany cost-sharing arrangement. A final decision has yet to be issued by the Tax Court due to other outstanding issues related to the case. At this time, the U.S. Department of the Treasury has not withdrawn the requirement to include share-based compensation from its regulations. Due to the uncertainty surrounding the status of the current regulations, questions related to the scope of potential benefits, and the risk of the Tax Court’s decision being overturned upon appeal, the Company has not recorded any benefit as of March 31, 2018. The Company will continue to monitor ongoing developments and potential impacts to its financial statements.
