Beingmate Baby & Child Food Co shares have more than halved in value on the Shenzhen stock exchange over the past three weeks, pushing their price 21 per cent below what Fonterra Cooperative Group paid for its 18.8 per cent stake in the Chinese infant formula maker.
Beingmate shares fell 9.6 per cent to 14.30 yuan, below the 18 yuan apiece that the Auckland-based dairy co-operative paid for 192.4 million shares in March.
The shares have more than halved from a record 30.95 yuan on the Shenzhen exchange in mid-June, as the Chinese stock exchange abruptly pulled back after surging 100 per cent since the start of the year.
The decline in the shares only amounts to a $16.6 million loss in New Zealand dollar terms compared to the $755 million ascribed to the holding when it was first bought, because the Kiwi has dropped 10 per cent against the yuan in that time.
Fonterra and Beingmate announced their global partnership last August to meet China's growing demand for infant formula and increase export volumes of Fonterra's Anmum infant formula brand. At the time, Fonterra had been hoping for a 20 per cent stake in the firm and flagged it would cost about $615 million.
