Export Hedge Accounting

7

To better reflect the exchange variations impacts in its result and in compliance with accounting standards IAS 39 and

CPC 38, Braskem decided to designate, as of May 1, part of its dollar-denominated liabilities as a hedge for its future

exports.

The exchange variation from these designated liabilities will be temporarily recorded under shareholders’ equity and

transferred to the income statement only when such exports occur.

If hedge accounting had not been adopted, the financial result in 2Q13 would have been an expense of R$ 2,111

million.
