The Serious Fraud Office is to announce within weeks whether it will lay charges against directors of several failed finance companies.
The office has been investigating eight failed finance companies, including Nathans Finance, Five Star Finance, Bridgecorp, Hanover and Blue Chip.
Chief executive Adam Feeley says the SFO has now made internal decisions on all cases about whether or not criminal charges will be laid.
Details are to be discussed with an external prosecution panel.
Mr Feeley says the office is looking at charging individuals. The most serious of the charges have maximum penalties of between five to ten years in prison.
Mr Feely says the SFO is still investigating Capital + Merchant: no decisions about prosecutions have been made.
