Braskem reported its 2Q13 earnings. EBITDA increased 12% from the previous quarter to R$1,051 million due to higher sales volumes, a positive foreign exchange impact, and cost reductions. The Mexico project construction advanced to 38% completion. Braskem adopted hedge accounting to better reflect exchange rate impacts. Leverage excluding Mexico declined to 3.01x due to debt reduction. Braskem will focus on strengthening client relationships, advancing industrial policies, boosting competitiveness through costs and capacity, progressing key projects, and maintaining financial strength.

7. Export Hedge Accounting

 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.
