Former chief executive officer of Anglo Irish Bank David Drumm faces two separate trials in the Dublin Circuit Criminal Court in April 2017 and in January 2018.
Mr Drumm will go on trial on 24 April 2017 on two offences.
He is charged with conspiring with other bankers from Anglo Irish Bank and Irish Life and Permanent to defraud investors, depositors and lenders by misleading them about the true value of Anglo's deposit books.
He is also charged with false accounting by furnishing false information to the market in September 2008, giving the impression that Anglo's deposits were €7.2bn greater than they actually were.
That trial is expected to take 12 weeks, the court heard today.
Mr Drumm faces a second trial on 15 January 2018 on 31 offences.
There are 16 charges relating to the alleged provision of unlawful financial assistance to ten developers and six members of Sean Quinn's family.
There are also 14 charges relating to the falsification of documents and one charge relating to a breach of an EU transparency directive. That trial is expected to take two months.
The court also heard that gardaí were consenting to a change in Mr Drumm's bail conditions - allowing him to sign on once a day at Balbriggan Garda Station, instead of twice.
Mr Drumm's solicitor, Michael Staines, said there was likely to be huge disclosure in the first case and asked for a slightly later date for trial.
But prosecuting lawyers said a lot of disclosure had already been made in previous cases and the disclosure process should be quicker than it had been to date.
Judge Terence O'Sullivan said he was firmly of the view that the case should be in a position to go ahead in a year.
The court was told both cases were likely to need expanded jury panels and time would be set aside in advance of the trial dates to allow juries to be sworn.
The first case will be mentioned again before the Circuit Criminal Court in November.
