Investors in property syndicates formerly run by SPI have been told to close ranks to the media.
Two separate investors in the syndicates, which notched up $25 million in accumulated losses during the 2014 financial year, say their manager, Taurus Group, wrote about not speaking to the media.
Taurus Group did not directly respond to the Herald's questions about the matter, citing confidentiality obligations in the syndicates' rules.
One investor saw the letter as an attempt to gag unit holders and called it "ridiculous".
As well as $25 million of accumulated losses, the syndicates' 2014 financial accounts reveal that almost $6.1 million of advances and accrued interest owing by related parties had been fully impaired.
