The company’s listed available-for-sale equity investments are susceptible to market price risk arising from uncertainties about the future value of the investments.

At the reporting date, the majority of equity investments were listed on the Toronto Stock Exchange.

Based on the share price of First Uranium Corporation over the past year and carrying value at 31 December 2011 of R61m, if First Uranium Corporation achieved the high that it achieved during 2011 of C$1.43 per share, other comprehensive income (OCI) would increase by R471m. If it achieved the low of C$0.14 per share, OCI would decrease by R9m. If the decrease was significant, an other-than-temporary impairment would be recorded.
