As a result of the impairment, the net assets of the company fell to $74.6 million at June 30, from $99.2 million a year earlier. The decline also reflected increased depreciation, operating costs and lower-than-expected output.
NZ Windfarms uses turbines supplied by Windflow Technologies, a Christchurch-based form that is struggling to make global sales. In October, NZ Windfarms exercised its option to acquire the Windflow business that had the contract to operate and maintain the wind farm including spare parts.
"The financial position of WTL remains a concern to directors," NZ Windfarms said today.
Early this year, NZ Windfarms began a strategic review with the aim of finding a buyer for the wind farm once it was completed. While the company has been in talks with potential buyers those discussions haven't resulted in a concrete proposal, it said today.
The company has concluded its original objective to be a developer of wind farms "no longer applies" and it is in the process of developing a new business model to reflect its position "as a single wind farm operator."
The company won't pay a final dividend.
