		Fiscal Year Ended December 31,				Fiscal Year Ended December 31,				Six Months Ended December 31,				Fiscal Year Ended June 30,
		2012				2011				2010				2010
Weighted average exercise price - Rand			—				119.17				93.89				90.84
Weighted average expected volatility (based on a statistical analysis of the share price on a weighted moving average basis for the expected term of the option)			—				46.4	%			50.2	%			52.0	%
Expected term (years)			—				5.90				3.0 - 4.2				3.0 - 4.2
Long-term expected dividend yield			—				1.70	%			1.00	%			1.00	%
Weighted average risk free interest rate			—				6.90	%			6.90	%			7.90	%
Weighted average fair value - Rand			—				51.66				55.06				43.82

The Group used the Monte-Carlo Simulation to value the PVRS under the Gold Fields 2005 Share Plan and the Gold Fields Limited 2005 Non-executive Director Share Plan. The inputs to the model for awards granted during the year were as follows:

Valuation Technique Monte Carlo

Assumptions used to Value Options

The Group uses the Monte-Carlo Simulation to value the Performance Shares. The inputs to the model for awards granted during the period were as follows:

		2012
Weighted average historical volatility (based on a statistical analysis of the share price on a weighted moving average basis for the expected term of the option)			36.4	%
Expected term (years)			3.00
Historical dividend yield			1.60	%
Weighted average three year risk free interest rate (based on US interest rates)			0.70	%
Weighted average fair value - Rand			R 162.14

A future trading model is used to estimate the loss in value to the holders of Bonus Shares due to trading restrictions. The actual valuation is developed using a Monte-Carlo analysis of the future share price of Gold Fields:

Weighted average historical volatility (based on a statistical analysis of the share price on a weighted moving average basis for the expected term of the option)			29.4	%
Expected term (months)			9 - 18
Historical dividend yield			2.70	%
Weighted average three year risk free interest rate (based on SA interest rates)			5.50	%
Marketability discount			1.6	%
Weighted average fair value - Rand			R 115.61

- Definition

Tabular disclosure of an equity-based arrangement (such as stock or unit options and stock or unit awards) with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain equity-based awards at future dates, sometimes including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares or units issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability.
