Income Taxes [Abstract]
Income Taxes	19. 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 months ended September 30, 2019, the Company's effective tax rate was impacted by the on-going losses incurred by certain of its South African businesses and the associated valuation allowances created related to the deferred tax assets recognized regarding net operating losses incurred by the Company's South African businesses and non-deductible expenses, including transaction-related expenditure, which was partially offset by tax expense recorded by the Company's profitable businesses in South Africa and South Korea. For the three months ended September 30, 2018, the Company's effective tax rate was significantly higher than the South African statutory rate as a result of a valuation allowance created related to net operating losses of approximately ZAR 223.4 million ($15.1 million translated at the average exchange rate for the three months ended September 30, 2018) incurred by its South African subsidiary, CPS, and non-deductible expenses, including transaction-related expenditure and non-deductible interest on the Company's South African long-term debt facility. Uncertain tax positions There were no significant changes in the Company's uncertain tax positions during the three months ended September 30, 2019. As of September 30, 2019, the Company had accrued interest related to uncertain tax positions of approximately $0.1 million on its balance sheet. The Company does not expect the 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 September 30, 2019 and June 30, 2019, the Company had unrecognized tax benefits of $1.0 million and $0.8 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 September 30, 2019, 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, 2016. 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.

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.
