Spain's Repsol posted a net loss and wrote down $1.5 billion in assets on Thursday. The COVID-19 health crisis has piled pressure on a sector already hurt by oil prices. The company revised down its gas price outlook for 2020 to $2 per million British thermal units, from $3. It burned cash, with a negative free cash flow of 217 million euros, but expected cash-flow from operations of 3.6 billion euros this year.
