The frequency of when books calculate losses and gains against international prices has been undisclosed for almost two years. Until mid-2018, prices were adjusted daily.
In 2018 former CEO Pedro Parente quit after coming under pressure to relax a policy of adjusting prices daily at the pump in response to global fuel price increases that triggered a debilitating truckers' strike. It does not prevent the company from adjusting prices at the pump up or down anytime. The company said it has registered robust operational results.
