West Coast write-downs hit Solid Energy

Write-downs on Solid Energy's West Coast assets knocked $46 million off the company's bottom line in the June year.

The state-owned coal miner's tax-paid profit slumped to $6.3 million in the year to June 30 from $33.7 million the previous year, its annual report shows.

Solid Energy's surplus before tax and write-downs increased to $54.9 million from $52.5 million.
