[1] The tax losses can only be used to offset future interest income generated by Orogen and can be carried forward indefinitely.
[2] Tax losses may be carried forward for ten years. These losses expire on a first-in first-out basis.
[3] Tax losses may be carried forward for five years. These losses expire on a first-in-first-out basis.
[4] These future deductions may be utilized against income generated by the individual tax entity concerned and do not expire unless the tax entity ceases to commercially operate for a period longer than one year. Under South African mining tax ring-fencing legislation, each tax entity is treated separately and as such these deductions can only be utilized by the tax entities in which the deductions have been generated.
[5] Tax losses are not available at December 31, 2013 as they were distributed as part of the Sibanye Gold spin-off.
