Income Tax [Abstract]
Income Tax	17. Income tax Income tax in interim periods For the purposes of interim financial reporting, the Company determines the appropriate income tax provision by first applying the effective tax rate expected to be applicable for the full fiscal year to ordinary income. This amount is then adjusted for the tax effect of significant unusual items, for instance, changes in tax law, valuation allowances and non-deductible transaction-related expenses that are reported separately, and have an impact on the tax charge. The cumulative effect of any change in the enacted tax rate, if and when applicable, on the opening balance of deferred tax assets and liabilities is also included in the tax charge as a discrete event in the interim period in which the enactment date occurs. For the three and nine months ended March 31, 2018, the tax charge was calculated using the expected effective tax rate for the year. The Company's effective tax rate for the three and nine months ended March 31, 2018, was 106.3% and 55.0%, respectively, and was higher than the South African statutory rate as a result of an impairment loss, non-deductible expenses (including transaction-related expenditure and non-deductible interest on our South African long-term facility), the impact of the changes in U.S. federal statutory tax rates described below and for the nine months ended March 31, 2018, a valuation allowance provided related to an allowance for doubtful working capital finance receivables created. For the three and nine months ended March 31, 2017, the tax charge was calculated using the expected effective tax rate for the year. The Company's effective tax rate for the three and nine months ended March 31, 2017, was 35.0% and 34.0%, respectively, and was higher than the South African statutory rate as a result of additional taxes payable resulting from the finalization of a tax review in South Korea, non-deductible expenses and the tax impact attributable to distributions from our South African subsidiary. New U.S. Tax Legislation On December 22, 2017, the Tax Cuts and Jobs Act (the " TCJA"), was enacted into law, significantly modifying U.S. federal tax laws. The TCJA reduces the federal statutory tax rate for corporations from 35% to 21% effective from January 1, 2018, eliminates alternative minimum tax for corporations, limits net operating loss carryforwards (and eliminates carrybacks), limits the deductibility of interest expense and transitions the system of U.S. international taxation of corporations from a worldwide tax system to a territorial tax system. Specifically, the transition to a territorial tax system is not expected to have a significant impact on the Company's future consolidated effective tax rate as it generates the majority of its taxable income in tax jurisdictions with tax rates higher (mainly South Africa, where its income is taxed at 28%, and Korea, where our income is taxed at 22%) than the new federal statutory tax rate of 21%. The Company is currently analyzing the impact of these changes; therefore, an estimate of the full impact on deferred tax assets and liabilities, income tax expense, net income and other affected accounts is not yet available. The Company has a June year end and therefore it will use a blended rate of 28.10% for its tax year ending June 30, 2018, in the U.S. Certain of the Company's deferred tax assets and liabilities which it expects will be utilized/ reversed during the period ended June 30, 2018, have been re-measured at this blended rate and those deferred taxes that the Company believes will only be utilized/ reversed in subsequent tax years, have been remeasured at 21%. The impact of the change in the tax rate on the Company's deferred taxes included in income tax expense during the nine months ended March 31, 2018, was $0.3 million. The Company has also provided an additional valuation allowance of approximately $0.6 million related to net operating loss carryforwards that it does not believe will be utilized as a result of the enactment of the TCJA. The TCJA also requires a U.S. shareholder of a specified foreign corporation to include a deemed repatriation of foreign earnings as part of the transition to a territorial tax system; however, the Company does not currently believe that it has a deemed repatriation transition tax liability. Uncertain tax positions There were no significant changes in the Company's uncertain tax positions during the three and nine months ended March 31, 2018. As of March 31, 2018, the Company had accrued interest related to uncertain tax positions of approximately $0.1 million on its balance sheet. The Company does not expect changes related to its unrecognized tax benefits will have a significant impact on its results of operations or financial position in the next 12 months. As of March 31, 2018 and June 30, 2017, the Company had unrecognized tax benefits of $0.5 million and $0.5 million, respectively, all of which would impact the Company's effective tax rate. The Company files income tax returns mainly in South Africa, South Korea, Germany, Hong Kong, India, the United Kingdom, Botswana and in the U.S. federal jurisdiction. As of March 31, 2018, the Company's South African subsidiaries are no longer subject to income tax examination by the South African Revenue Service for periods before June 30, 2013. The Company is subject to income tax in other jurisdictions outside South Africa, none of which are individually material to its financial position, statement of cash flows, or results of operations.
