The impairment charges wiped out the remaining goodwill Independent attributed to the business, representing the excess cost of the acquisition above the fair value of net identifiable assets, valued at $327.5 million when Asahi's New Zealand vehicle amalgamated with the holding company of the former owners.
Independent also wrote off $6.2 million of goodwill allocated to The Mill Retail Holdings, the 35-store retail chain purchased in 2013 for $18.2 million. Its sale of The Mill should complete by September.
The expansion into retail came after Independent Liquor launched boutique beer brand Boundary Road in 2011, building on its dominance in the local ready-to-drink market with brands including Woodstock Bourbon and Vodka Cruisers. It accounts for 11 per cent of pack beer sales, according to the company's website.
Independent's accumulated losses of $241.8 million ate into equity, which was valued at just $1.5 million at December 31.
The company boosted revenue 5.8 per cent to $378.3 million, a slower pace of growth than its cost of sales, meaning gross margins shrank to 24.2 per cent from 24.7 per cent in 2013.
