Net interest expenses decreased to US$7.3 million in the first half of 2012 compared to US$11.1 million in the same period of 2011.

Other financial results recorded a loss of US$3.4 million during the first half of 2012, compared to a loss of US$11.4 million during the first half of 2011. These results largely reflect gains and losses on net foreign exchange transactions and the fair value of derivative instruments and are partially offset by changes to our net equity position. These gains and losses are mainly attributable to variations in the exchange rates between our subsidiaries' functional currency (other than the US dollar) and the US dollar, in accordance with IFRS.

Equity in earnings of associated companies generated a gain of US$30.2 million in the first half of 2012, compared to a gain of US$47.0 million in the first half of 2011. These gains were derived mainly from our equity investment in Ternium.

Income tax charges amounted to US$293.0 million in the first half of 2012, equivalent to 25% of income before equity in earnings of associated companies and income tax, compared to US$234.0 million in the first half of 2011, equivalent to 29% of income before equity in earnings of associated companies and income tax. During the first half of 2012, the tax rate benefited from a more favorable mix of companies.

Income attributable to non-controlling interests amounted to US$8.7 million in the first half of 2012, compared to US$22.3 million in the corresponding semester of 2011. In May 2012, we completed the acquisition of all the non-controlling interests of Confab.

Cash Flow and Liquidity of 2012 First Half

Net cash provided by operations during the first half of 2012 rose to US$1,019.2 million, compared to US$490.8 million in the first half of 2011, mainly due to higher result and lower investments in working capital in the first half of 2012.

Capital expenditures amounted to $400.9 million in the first half of 2012, compared to US$461.8 million in the first half of 2011.

Following our investments in Brazil during the first semester of 2012, amounting to US$1.3 billion(US$504.6 million in Usiminas and US$758.5 million in Confab) and the payment of a dividend of US$295.1 million, our financial position at June 30, 2012, amounted to a net debt position (total borrowings less cash and other current investments) of US$540.5 million, compared with a net cash position of US$323.6 million at December 31, 2011.
