The wreck of Ross Asset Management (RAM) has highlighted some of the important differences between fully-regulated funds management products and other nebulous services operating on the legislative border.
As myself, Brian Gaynor and others have pointed out RAM head, David Ross, was able to get away with it because the rules allow investors to sign away some important legal protections if they are so inclined.
The PwC report confirmed my earlier guess that Ross was in fact running a discretionary investment management service (DIMS), where clients grant the operator authority to invest money on their behalf. Usually DIMS operators - who are often stockbrokers - pool client money into similar portfolios to gain economies of scale but there is no formal legal fund structure.
Also unlike regulated financial products, it's just about impossible to know how much money invested in New Zealand under DIMS arrangements.
However, according to some of the industry people I've spoken to, there's probably a considerable amount of money managed in the DIMS way.
