Wan Kei (HKG:1718) forecasts it will swing to a loss of at least HK$11 million in the half-year ended Sept. 30 from a profit of HK$18.4 million in the year-ago period, according to a Wednesday filing with the Hong Kong Exchange.

The construction company's expected loss is attributed to impairment losses on financial and contract assets, as well as higher selling and general and administrative costs, the filing said.

Wan Kei plans to release its half-year results on Nov. 27.
