Refining NZ today said it will take a non-cash impairment charge of about $220 million, before tax, in its six month accounts due to disruption arising from the Covid-19 pandemic.
After tax, the charge comes to $158m.
The impairment charge is primarily because of revised refining margin assumptions, reflecting the excess refining capacity in the Asia-Pacific region and the effects of the Covid-19 pandemic on transport fuel demand, particularly jet demand.
Refining NZ sets its long-term refining margin assumptions based on independent energy analyst forecasts.
The company, which operates New Zealand's only oil refinery, said it would remain comfortably within the 45 per cent senior debt gearing covenant under its facility agreements at 27 per cent after the impairment.
