At 30 June 2011, if commodity prices had moved by a reasonably possible 5%, as illustrated in the table below,  with all other variables held constant, post tax losses and equity would have been affected as follows: Post tax profit Other Comprehensive Income higher/(lower) higher/(lower) 2011 2010 2011 2010 Judgements of reasonably possible movements: Price + 5% 68,688  172,563  - - Price - 5% (68,688) (172,563) - - Post tax profit Other Comprehensive Income higher/(lower) higher/(lower) 2011 2010 2011 2010 Judgements of reasonably possible movements: Price + 10% 15,979  30,055  3,430,333  2,358,504  Price - 10% (15,979) (30,055) (3,430,333) (2,358,504) (d) Foreign Currency Risk Exposure  (e) Liquidity Risk  78  NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2011 Equity Security Price Risk The Consolidated Entity’s objective is to maintain a balance between continuity of funding and flexibility through  the use of finance and hire purchase leases. Liquidity risk arises from the financial liabilities of the Consolidated Entity and the subsequent ability to meet the  obligations to repay the financial liabilities as and when they fall due. As a result of sales receipts being denominated in Malaysian Ringgit and US dollars, the Consolidated Entity’s  cash flows can be affected by movements in the Malaysian Ringgit/Australian dollar and US dollar /Australian  dollar exchange rates. The Consolidated Entity’s exposure to foreign currency is however not considered to be  significant. A sensitivity of +10% or -10% has been selected as this is considered reasonable given recent fluctuations in  equity prices and management’s expectations of future movements. The movements in other comprehensive  income are due to possible higher or lower equity security prices from investments in equity securities that are  classified as available-for-sale financial assets (refer to note 2(l)). The overall sensitivity for post tax losses and  equity in 2011 is higher due to increases in the market value of the underlying securities during the financial  year and the increased equity investments in Mongolian Resource Corporation Limited, Independence Group NL,  Westgold Resources Limited and Aziana Exploration Corporation (refer to notes 17 and 19). A sensitivity of +5% or -5% has been selected as this is considered reasonable given recent fluctuations in tin  commodity prices and management’s expectations of future movements. The movements in commodity prices  are due to possible higher or lower commodity prices from tin sales that are classified as trade receivables (refer  to note 2(h)). The sensitivity in 2011 is lower due to a lower trade receivables balance at 30 June 2011 due to the  sale of 50% of the Renison Tin Project in the previous financial year. The Consolidated Entity’s revenues are exposed to equity security price fluctuations arising from investments in  equity securities. At 30 June 2011, if equity security prices had moved by a reasonably possible 10%, as illustrated in the table  below, with all other variables held constant, post tax losses and equity would have been affected as follows:
