Standard Development Group (HKG:1867) expects a minimum net loss of HK$17 million for the six months ended Sept. 30, wider than HK$7.1 million logged for the same period last year, a Friday Hong Kong bourse filing said.

The construction and engineering investment holding company attributed the expected increase in loss to a decrease in revenue from construction and petroleum, an increase in impairment losses, an increase in expenses, and the fact that the company's two bio-nature gas projects have yet to make any contribution.
