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 or extraordinary 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 six months ended December 31, 2016, the tax charge was calculated using the expected effective tax rate for the year. The Company's effective tax rate for the three and six months ended December 31, 2016, was 36.4% and 33.6%, 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. The Company's effective tax rate for the three and six months ended December 31, 2015, was 38.7% and 34.7%, respectively, and was higher than the South African statutory rate as a result of non-deductible expenses (including consulting and legal fees) and the tax impact, including withholding taxes, of distributions from subsidiary companies in foreign jurisdictions. Uncertain tax positions There were no changes during the three months ended December 31, 2016. The Company utilized approximately $0.3 million of its unrecognized tax benefits during the six months ended December 31, 2016 as a result of the finalization of a tax review in South Korea. As of December 31, 2016, 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 December 31, 2016 and June 30, 2016, the Company has unrecognized tax benefits of $1.7 million and $1.9 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, India, the United Kingdom, Botswana and in the U.S. federal jurisdiction. As of December 31, 2016, 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, 2012.

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 or extraordinary 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 six months ended December 31, 2016, the tax charge was calculated using the expected effective tax rate for the year.
