The contribution margin reduction, that followed the lower spreads of the international market, more than offset the positive effects from exchange variation and the higher sales volume. EBITDA was positively affected by recognition of the compensation received under the Sunoco supply agreement and by the prepayment of tax installments under the Refis program.
