21.       Taxation

The effective rate of tax in the nine months to September 30, 2015 was -1% (2014: -5%).

The effective rate of tax in the nine months to September 30, 2015 on income from continuing operations is negative primarily due to the release of certain valuation allowances and the impact of the finalization of various tax returns in the period.

The effective rate of tax in the nine months to September 30, 2014 on income from continuing operations was negative primarily due to the recognition of a net tax credit in relation to the settlement of tax positions with the Canadian revenue authorities.
