Income Tax Disclosure [Abstract] |
Income Taxes | 14. Income Taxes The 2017 Tax Act was enacted in December 2017. The 2017 Tax Act, among other things, reduces the U.S. federal corporate tax rate from 35% to 21%, effective January 1, 2018, creates new taxes on certain foreign earnings and may require companies to pay a one-time transition tax on undistributed earnings of certain foreign subsidiaries that were previously tax deferred. The Company is not required to pay a one-time transition tax on earnings of our foreign subsidiaries since the Company had accumulated foreign losses on a consolidated basis. As a result of the 2017 Tax Act, during the six months ended March 31, 2018, the Company revalued its U.S. deferred tax assets based on the new U.S. federal tax rate of 21%, which resulted in a reduction to its deferred tax assets of approximately $8.1 million. The reduction in deferred tax assets was completely offset by a like reduction to the valuation allowance. Consolidated income tax expense for the three months ended March 31, 2019 was $0.6 million compared to a tax benefit of $0.7 million for corresponding period of the prior fiscal year. Consolidated income tax expense for the six months ended March 31, 2019 was $0.6 million compared to a tax benefit of $0.7 million for corresponding period of the prior fiscal year. The $0.6 million tax expense for both periods of fiscal year 2019 primarily reflects foreign withholding tax on rental income earned in Nigeria during the three months ended March 31, 2019. The income tax benefit for both periods of fiscal year 2018 reflects a $0.7 million tax refund resulting from the filing of an amended U.S. tax return in the three months ended March 31, 2018. The Company is currently unable to record any tax benefits for its tax losses in the U.S. and Canada due to the uncertainty surrounding its ability to utilize such losses in the future to offset taxable income.
