It's long been suggested Fonterra should be broken up into a commodity business and a listed offshoot making value-added products. Opinion is divided and there are complex issues in play as well as competitive interests.
A February Cabinet paper which launched the DIRA review said one area for discussion was "Fonterra's co-operative structure and its impact on Fonterra's ability to raise capital to invest in innovation and value creation". The debate must be put on a professional footing.
Peters - who is now standing in for the Prime Minister while Ardern is on maternity leave - should have his private sector adviser's estimates verified and updated by Treasury officials and Ministry of Foreign Affairs and Trade officials and presented through an appropriate Cabinet paper. Particularly if the Coalition (and the Acting Prime Minister himself) are to continue to rely on them to justify a wide-ranging look at the dairy sector and the potential changes which could see Fonterra restructured.
When it comes to the $800m expected biosecurity costs, Peters was not being entirely fair to Fonterra. But he was making a point that the coalition Government is standing behind the dairy sector and wants to ensure the taxpayer dollars are well spent. First some context.
It is important to note Fonterra is not the only NZ blue chip to burn through a huge amount of cash in recent years. Peters' $1.383b estimated losses via Fonterra are more than, for instance, the $952m losses over 2017/2018 that Fletcher Building unveiled in February. Shareholders have to wear that themselves. At tomorrow's Investors' Day in Sydney, Fletchers CEO Ross Taylor will reveal his strategy for turning that company around.
Like Fonterra there are also downstream impacts from the Fletcher fiasco. But it does not have the Government on its tail.
The company has parked its vertical construction business while it sorts itself out. This will have an impact on construction pricing across the board.
Importantly, accountability has been exacted at governance and CEO level. At Fonterra only the CEO has yet to pay a price. Just a week ago, Cabinet Minister and NZ First MP Shane Jones called for Fonterra chairman John Wilson to resign.
But loose talk by Jones and NZ First MP Mark Patterson has given an unfortunate impression their venom was fuelled as much by political payback over the dairy sector's opposition to proposed policy changes during last year's election campaign as hard-nosed analysis.
Peters' resort to calculations this week was an attempt to shift the debate on from last week's.
Purists will take issue with the breakdown Peters' office provided. But for the purpose of clarity it is useful to reprise the official's words. The estimated loss to date was derived from:
• $750m worth of investments made by Fonterra in the Beingmate deal which were effectively lost (combination of a write down in company value and half year negative result);
• $300m loss of return resulted from the sales for the last three years;
• $183m pay out to Danone for the WPC80 incident (botulism scandal);
And the generic collateral cost/damage from the Fonterra botulism issue from regulatory and compliance work ie Government agencies dealing with the issues and a loss of business for other NZ companies - approximately $150m. This, the official said, made up the total estimated loss to date of $1.383b.
Expect Peters and Jones to keep hammering this point. Irrespective of the back of the envelope calculations, the figures are sobering.
