Overall Commentary

GOL expects a December quarter operating margin of 6.5-7.0%, consistent with the updated guidance provided on the earnings call last November. Such margin for the quarter includes non-recurring expenses related to fleet restructuring. Consolidated passenger unit revenue (PRASK) for the December quarter was up 6.5-6.8% year over year, driven by demand trends and improving domestic yields as GOL's capacity actions and revenue management strategies continue to benefit results. For the December quarter, GOL expects unit revenue (RASK) to increase 6.9-7.2%. Non-fuel unit costs (CASK ex-fuel), excluding non-recurring expenses related to fleet restructuring, are expected to be down approximately 5% for the December quarter versus same quarter of the prior year. GOL reduced total debt including finance leases by R$1.3 billion in the quarter for a total of more than R$3.2 billion debt reduction in 2016.
