A Grant Thornton report found on the "balance of probabilities" RTE understated Ryan Tubridy's salary to make his payment seem lower than €500.000 euro a year.
The report also finds that a payment of €120,000 which Mr. Tubridy was entitled to as an exit fee for his 2015 contract, was not made by RTÉ as the presenter waived the entitlement.
Ryan Tubridy has welcomed the findings of the Grant Thornton report.
He says he's now "committed to re-establishing the confidence and trust" of his colleagues and listeners.
He also repeated his offer to "publish the details of any future RTÉ contract".
