Why do you think Hanjin went bankrupt? That's right, in part, they had to pay huge expensive charters to DAC when the revenue they earned from those ships wasn't even 1/4th what they were paying
Same with Zim.
If DAC is lucky, no more of its counterparties will go bankrupt, but every day brings DAC one day closer to the end of its luxurious overpriced revenue stream.
