Knowledge proves fatal to accountant’s $7m share lawsuit

Rene Georges Pentecost, a former in-house accountant for the RS Group, claimed to have been duped into investing in its holding company, Rapid Securities, by its founders in 2017, including in alleged conversations where he was told it would be worth $100 million.

About three years later, Rapid Securities entered into voluntary administration, but was soon subject to a deed of company arrangement and control was returned to the founders by the end of the year.

In proceedings before the Supreme Court of Queensland, Pentecost sought to recover all or some of the $7 million investment he and his companies lost through various orders for damages or compensation.

But Justice Catherine Muir was not persuaded Pentecost was deceived or misled in contravention of Australian Consumer Law (Qld).

It emerged during cross-examination that Pentecost had “deliberately downplayed the extent of his role and knowledge of the financial structure and operations of RS Group”, and only admitted to this when one of the founders disclosed documents about his various task lists.

Pentecost was also found by Justice Muir to have been “selective about disclosing all of the relevant facts leading up to his purchase of the shares, including about the extent of his own due diligence and knowledge of the provisioning of the loans".

Justice Muir added it would have been highly unlikely for a person in Pentecost’s position to have restricted access to financial data. If it were the case, Justice Muir said there should have been internal emails requesting access or complaining about the restrictions.

One of the founders, Russell Keith Birse, was also found to have downplayed parts of his evidence, including repeatedly depicting Pentecost as an experienced company accountant “when on any view he was not”, and the authority his position gave him over Pentecost.

Nevertheless, Justice Muir was not satisfied that Birse had told Pentecost that Rapid Securities was worth about $70 million and would be worth over $100 million by the following year.

Justice Muir did accept it was “objectively likely” Birse told Pentecost that he and his fellow founders were planning to sell more of their shares in the future “after the business is worth $100 million plus”, but said dismissed this being a reference to “next year”.

“Birse was an experienced businessman and it is inherently unlikely that he would make definitive statements about the future value of the business when there are so many variables that can impact that assessment,” Justice Muir said.

Pentecost did succeed in making out the allegation that he was told Rapid Securities loan book was worth $70 million. He was also successful in his claim that he was shown three spreadsheets detailing the profits and loan book value for two financial years.

In taking Pentecost to certain figures, it is “objectively likely” Birse said the loan book is sitting around $70 million “give or take”.

However, Justice Muir said this representation could not be correctly characterised as misleading or deceptive conduct.

As company accountant, Pentecost had access to and knowledge of the financial records and accounting systems maintained by the company, and spreadsheets were not being shown to “a layperson devoid of an understanding of financial accounting information and inside knowledge of the business of the company”.

Pentecost would have also known the values in the spreadsheet were based on various assumptions and should be seen in the context “that it was a prediction, not a guarantee of what might occur”.

Even if the court were wrong about these findings, Justice Muir said she was not satisfied that Pentecost was induced to enter into the share sale agreement on the basis of the representations he alleged.

For one thing, evidence showed that Pentecost was sceptical of the $70 million valuation of Rapid Securities because he made his own inquiries into whether Rapid Securities had undertaken a valuation. He also arrived at the figure of $40 million as part of a business proposal he put to his family.

Justice Muir added that Pentecost knew, through his solicitors, that he was paying an unknown premium for the shares, that he had conducted his own research into the venture over 18 months, and that he continued to investigate the viability of the investment with the assistance of financial advisers.

Turning to the spreadsheets, Justice Muir said she was not satisfied that Pentecost would have relied on them prior to the investment.

While Pentecost sent the spreadsheets to his personal email address, he never looked at them again. If the figures within them played a part in his decision, “it is reasonable to assume he would have examined the spreadsheets again in some detail,” but he did not.

“At the very least, if the figures in any of the spreadsheets were important to Pentecost’s decision to enter into the share sale agreement, it is reasonable to assume that he would have, at the very least, bothered to look at the spreadsheets again,” Justice Muir said.

Further, if those figures were important, Justice Muir said it could be assumed Pentecost would have reproduced them in the business proposal to his family, but chose not to. Instead, he arrived at his own projections for profit and the loan book, with the loan book sitting at around $45 million.

It was accepted that Pentecost did not understand what Birse had been saying during conversations about the spreadsheets, and it is reasonable to infer that is another reason they weren’t relied on in the proposal.
