Danaos Corp's results have landed well into the ledger's negative side, thanks to a hefty loss on part of its fleet.

The John Coustas-led company posted a net loss of $181m versus a $22.8m profit during the same period last year, mainly due to a $210m impairment charge on 10 ships.

Adjusted earnings came in at $36.6m, up from $31.2m
