China HK Power Smart Energy Group (HKG:0931) expects a loss attributable to owners between HK$50 million and HK$65 million for the six months ended Sept. 30, wider than HK$47 million logged for the same period last year, a Friday Hong Kong bourse filing said.

The natural gas distribution company attributed the increase in loss to a one-off expense incurred during the reporting period related to a certain legal proceeding.
