Lumina Group (HKG:1162) expects an attributable loss of HK$13.6 million for the year ended March 31, down from HK$29.8 million a year prior, a late Thursday filing with the Hong Kong bourse said.

Shares of the provider of building fire safety services were down nearly 3% in Friday afternoon trading.

The anticipated lower loss was mainly due to a higher gross profit margin, a net of reversal on impairment losses on trade receivables and contract assets, and lower administrative expenses.
