The former Guinness & Mahon banker and architect of the Ansbacher Deposits, the late Mr Des Traynor, traded in CRH shares for his banking clients while serving as chairman of CRH, the Ansbacher report indicates.

The appendices of the huge report take some time to read but in the interview with Joe Malone, the former director general of Bord Fáilte, it appears the inspectors reviewed some share dealings Mr Traynor conducted on behalf of Mr Malone.

A Guiness & Mahon nominee company, Mars Nominees, was used for the dealings and some of the profits were placed in an Ansbacher account. Among the shares being traded in 1988, according to the inspectors' report, were AIB, Bank of Ireland, Arran Energy and CRH. The profits from the share dealings were placed in Mr Malone's Ansbacher account.

You might have thought that with the level of information available to the late Mr Traynor, his clients might have the edge. Not so, apparently. According to the interview with Mr Malone, the transactions Mr Traynor oversaw were not always profitable.

"I had losses and profits because Atlantic Resources and a number of them didn't do so well," Mr Malone told the inspectors.
