US authorities’ hedge fund probe
The US authorities have been investigating the company since last year on whether senior manager Corey Ribotsky defrauded investors about their returns and the holdings of his funds.
Mr Ribotsky managed more than $780m in hedge fund assets last year.
The company reported eight years of positive returns in its biggest fund starting 2001.
NIR invests its hedge-fund assets mainly in small public companies through privately negotiated deals and mostly receives notes that could be converted into stock at a discounted rate.
The authorities are investigating whether NIR valued certain notes at a higher level than the underlying value of the companies.
