KEY POINTS:
Shares in healthcare provider Metlifecare plunged 9 per cent, or 49c, to $5.01 after it reported a December half-year net loss of $12.3 million.
Last year under different accounting rules it reported a net profit of $14.6 million. Its property was valued down by $10.7 million.
The company said the main driver for the result came from the new international accounting rules that meant unrealised property revaluation gains or losses had to be included.
