The situations warranting cancellation include someone attempting to take over Vital, another unitholder gaining more than a 6 percent stake "where it is considered material and adverse," the "commencement of a co-ordinated campaign by unitholders to re-open the fees and governance review" or "the commencement of material regulatory intervention."
The regulator, the Financial Markets Authority, says it has been following developments involving Vital Healthcare but "we have been clear that we regard this issue as a dispute between market participants in which the FMA does not have a role.
"The FMA has, and will continue to engage with the supervisor to understand the work it is doing as the front-line regulator of Vital as a managed investment scheme and NorthWest as the MIS manager."
NorthWest owns nearly 25 percent of Vital's units. A March 7 substantial shareholder notice shows Forsyth Barr Investment Management owns just over 7 percent.
NorthWest bought Vital's management contract for $11.5 million in 2011 and has since collected well over $100 million in fees, including $22.1 million in the six months ended December.
The change in the fee structure follows agitation from Vital's unitholders who accused NorthWest of treating Vital like a piggy-bank.
New Zealand Shareholders' Association chief executive Michael Midgley says that "at first sight, the new fee structure appears to be positive but a thorough reading of the announcement is disappointing."
He's particularly disappointed that independent chair of the management company, Claire Higgins, has resigned and has been replaced by NorthWest president Bernard Crotty. One of the two remaining independent directors on the five-person board is being given a casting vote.
NZSA will be conducting "a thorough analysis" of the new fee structure, Midgley says.
The just-completed fees and governance review was conducted by the management company's full board, at odds with its own board charter which says such a review should be conducted by a committee of independent directors.
Some of the additional new fees look as if they will be particularly lucrative for NorthWest.
For example, NorthWest has committed to buying A$1.26 billion worth of property currently owned by ASX-listed Healthscope, a transaction it will likely cause Vital to be part of.
Under the new fee structure, NorthWest would charge Vital 1.5 percent of the purchase price - it has already charged Vital $8.2 million for the Healthscope deal, even though Vital isn't part of that deal yet and even though Vital lent NorthWest A$81 million to secure a stake in Healthscope. If Vital isn't part of the Healthscope deal, NorthWest will refund Vital only $5.2 million of that $8.2 million.
Under the new fee structure, NorthWest would also charge Vital up to 20 percent of the annual rental on any new leases as well as leasing renewal fees, rent review fees, property management fees and a facilities management fee ranging from 1-2 percent of gross income.
NorthWest would also charge a development fee of 4 percent of committed spend as well as a project management fee of 2 percent of committed spend.
The manager has already committed Vital to spending $223 million on developments within its existing portfolio over the next three years, including $80 million before June 30.
