EQUITY INSTRUMENTS ISSUED PURSUANT TO BEE TRANSACTIONS 2014 transactions On April 16, 2014, the Company issued 4,400,000 shares of its common stock pursuant to the BEE transactions discussed in Note 14. The charge related to the equity instruments issued pursuant to the BEE transactions was determined to be approximately $11.3 million and was expensed in full during the year ended June 30, 2014, because the BEE partners owned the shares on the issue date. This was a book entry and no cash was actually paid. The charge recorded was determined as the difference between the fair value of the loans provided to the BEE partners and the fair value of the equity instruments granted to the BEE partners. The fair value of the loans provided to the BEE partners was determined to be their face value. The fair value of the equity instruments was calculated utilizing an adjusted Monte Carlo simulation discounted cash flow model which was developed for the purpose of the valuation of these BEE transactions. Cash flows were calculated for each simulated share price path, taking into account the bespoke features of the BEE transactions, as well as the expected interest and capital repayments (funded through the expected sales of BEE shares). The "adjustment" to the Monte Carlo simulation model incorporates a "jump diffusion" process to the standard Geometric Brownian Motion simulation, in order to capture the discontinuous share price jumps observed in the Company's share price movements on stock exchanges on which it is listed. Therefore, the simulated share price paths capture the idiosyncrasies of the observed Company share price movements. For each simulation, the resulting expected cash flows were discounted to the valuation date. The Company used an expected volatility of 21.04%, an expected life of five years, a risk free rate of 7.90% and no future dividends in its calculation of the fair value of the equity instrument. The estimated expected volatility was calculated based on the Company's 30 day VWAP share price using the exponentially weighted moving average of returns. 2012 transaction On April 19, 2012, the Company issued an option to purchase 8,955,000 shares of its common stock to a BEE consortium pursuant to a BEE transaction that it entered into on January 25, 2012. The option expired unexercised on April 19, 2013. The fair value of the option was determined as approximately $14.2 million and was expensed in full during the year ended June 30, 2012 because the option vested immediately on the grant date. This was a book entry and no cash was actually paid. Accordingly, the expense recorded during the year ended June 30, 2012, was not reversed during the year ended June 30, 2013, because the option had vested in full on the grant date. The fair value was determined on the date that all conditions to the BEE transaction had been fulfilled using the Cox Ross Rubinstein binomial model. The Company used an expected volatility of 47%, an expected life of one year, a risk free rate of 0.90% and no future dividends in its calculation of the fair value. The estimated expected volatility was calculated based on the Company's 250 day volatility.

17. EQUITY INSTRUMENTS ISSUED PURSUANT TO BEE TRANSACTIONS

2014 transactions

On April 16, 2014, the Company issued 4,400,000 shares of its common stock pursuant to the BEE transactions discussed in Note 14. The charge related to the equity instruments issued pursuant to the BEE transactions was determined to be approximately $11.3 million and was expensed in full during the year ended June 30, 2014, because the BEE partners owned the shares on the issue date. This was a book entry and no cash was actually paid. The charge recorded was determined as the difference between the fair value of the loans provided to the BEE partners and the fair value of the equity instruments granted to the BEE partners.

The fair value of the loans provided to the BEE partners was determined to be their face value. The fair value of the equity instruments was calculated utilizing an adjusted Monte Carlo simulation discounted cash flow model which was developed for the purpose of the valuation of these BEE transactions.

2012 transaction

On April 19, 2012, the Company issued an option to purchase 8,955,000 shares of its common stock to a BEE consortium pursuant to a BEE transaction that it entered into on January 25, 2012. The option expired unexercised on April 19, 2013.
