3.7 Free Cash Flow

Operating cash flow of Braskem in 2Q10 was R$771 million, compared to R$1.1 billion in the previous quarter, corresponding to a reduction of R$285 million. In 2Q10, working capital contributed with R$288 million. The key drivers of this increase were (i) the increase of R$755 million in the Suppliers line, (ii) the positive variation of R$294 million in the Marketable Securities line, related to the shortening of transactions maturities, which were reclassified as cash equivalents; partially offset by (iii) the negative variation of R$328 million in the Accounts Receivable line, due to Quattor s increased sales and the booking of PP America s sales (which had no balance sheet in 1Q10) and (iv) the increase of R$461 million in our Inventories, due to the increased volume of resins in our inventories, as previously explained.

As a result of the prepayment of debt, there was an increase in Interest Paid in the non recurring amount of R$ 44 million. This line was also impacted by the debt extension.

In 1H10, Free Cash Flow was negative R$670 million, compared with positive R$633 million in the same six-month period of 2009. The decrease basically reflects the acquisitions of Quattor, Polibutenos, Unipar Comercial and Sunoco Chemicals for R$1.4 billion in 2010.
