The case was one of a string involving the use of convertible notes to finance trans-Tasman acquisitions in the 2000s, most of which have been either lost or settled before they got to court.
In an explanatory memorandum last month ahead of a shareholder vote on the NZME demerger, APN said the dispute involved tax of $64 million for the period up to Dec. 31, 2014, when the transaction was completed and the IRD was seeking to impose penalties of between 10 and 50 percent of the tax in dispute as well as the tax claimed. NZME had tax losses of $48 million to offset any tax payable, it said.
In another dispute, the IRD indicated it intended issuing a Notice of Proposed Adjustment last month relating to non-resident withholding tax and thin capitalisation rules following an audit of certain transactions to finance the acquisition of mastheads by a New Zealand branch of an APN Australian entity.
In May APN expected the NOPA would say that around $27 million was owed in respect of the branch financing arrangement and the tax losses couldn't be used to offset the non-resident withholding tax. APN also believed the IRD would seek to impose penalties in respect of the disputed taxes.
The explanatory memorandum said that following the demerger associated with the NRWT would remain with APN and the risk around thin capitalisation would be spread across the relevant APN and NZME entities.
The Australian Tax Office is also auditing the New Zealand branch of the Australian APN entity in relation to the New Zealand mastheads, and both the ATO and IRD were also auditing or reviewing other matters within the APN Group, the memo said.
Under the demerger tax conduct deed, a "coordinating party" was to be nominated to deal with each tax matter with the costs incurred borne by the party primarily at risk, it said.
The demerger of NZME, which has newspaper, online, and commercial radio assets, has gained shareholder and regulatory approvals and APN has also sold its Australian regional newspaper titles to News Corp for A$36.6 million, retaining a still-profitable Australian commercial radio network and outdoor advertising business.
NZME and rival publisher Fairfax Media are in talks over creating a merged media group from their New Zealand assets.
