"During the year ended 30 June progress with licensing, turbine sales and turbine project developments have fallen short of expectations," it said.
Iles agreed to provide the shareholder loan facility in July 2012, giving the company the funds to undertake its UK wind turbine projects.
As at June 30, the aggregate liability under the loans was $20.7m with a security over the 'wind turbine' fixed assets $10.2m and work in progress and inventories of $2.7m, notes to its accounts say. It is recorded as a current liability "as the negative equity as at 30 June 2017 places the company in breach of the loan covenants and enables the lender to call the loans," although Iles has told the company he won't call any of the loans before October 31 this year.
Shareholders will be asked to vote on the restructuring and the conversion of 17.8 million preference shares to 53.5 million ordinary shares at a meeting, it said.
"It is intended that the company continue as a going concern without continuing to rely on the sole support of its largest shareholder, with a small engineering team, primarily focused on managing the operation and maintenance of the UK turbines," it said. "The company also intends to address licensing opportunities as they arise. Details of this downsizing will be announced in due course following consultation with staff."
"If the proposed financial restructuring does not proceed or overheads are not able to be reduced significantly, the directors would have to re-consider the going concern assumption and take appropriate action," the Windflow notes say. "If that process results in the directors concluding that the group was no longer a going concern, the net assets of the company and the group would reduce significantly and this would likely result in a material negative effect."
Windflow shares last traded at 1.3 cents on the NZAX market, valuing the company at $502,000. The shares have shed 93 per cent of their value in the past five years.
