CSI Properties (HKG:0497) expects an attributable loss of between HK$900 million and HK$950 million for the six months ended Sept. 30, compared with a profit of HK$58 million a year prior, a Thursday bourse filing said.

The property developer attributed the anticipated swing to loss mainly to adverse changes in the fair value of its investment properties and the impairment provision for a joint venture's properties for the period.
