The Office of the Director of Corporate Enforcement has said it has substantively completed its investigations in the former Anglo Irish Bank.
The office's new director Ian Drennan said 60 charges had been brought against a number of individuals following the probe.
Mr Drennan said the role of the office had now moved to being one which supported the Director of Public Prosecutions. He said this related to following obligations regarding disclosing information to people facing charges.
He said this is a "major undertaking" and is likely to be a significant and continuing feature of the office's work for some time to come.
The cases are expected to come to trial early next year.
Charges have been made against Anglo's former chairman Seán FitzPatrick, finance director Willie McAteer and senior executive Pat Whelan.
Outside the Anglo investigation, the office received 2,400 reports, referrals and complaints last year from liquidators, auditors, professional bodies, other regulatory authorities and members of the public.
In its annual report for 2012, the ODCE said that decisions were issued in respect of over 1,200 liquidators' reports, while a total of 227 company directors were restricted, and another 15 disqualified by the High Court as a result of liquidators' applications.
A total of 16 criminal convictions were secured in the district court and files in another three cases were submitted to the DPP for consideration.
Mr Drennan said that the office has also devoted considerable thought to its future enforcement strategy. This includes certain changes to its office's structure as well as its case management arrangements, while steps are also being taken to utilise certain statutory powers on a more regular basis.
