Joe Duffy's stellar pay increase from RTE contributed to the cash pile at his media firm soaring to €458,456 last year.
New figures lodged by Duffy's media firm, Claddaghgreen Ltd, show that accumulated profits increased from €303,854 to €373,059 in the 12 months to the end of April last.
During the same period, the company's cash pile increased from €419,068 to €458,456.
The gains last year fall short of the profits enjoyed by the company in 2015, when the firm's cash pile more than doubled and accumulated profits increased by more than €150,000.
The most recent figures published by RTE last year show that the Liveline presenter is the second highest paid presenter at RTE behind Ryan Tubridy.
This followed Mr Duffy's pay increasing by more than €100,000 from €303,750 in 2013 to €416,893 in 2014 and the pay increase coincided with the Dubliner taking on more TV work.
The latest JNLR figures show that Duffy's Liveline continues to prosper. After overtaking Marian Finucane's Saturday show it is now is the second-most popular radio programme in the country behind 'Morning Ireland'.
The JNLR figures show that the show has 398,000 listeners - a gain of 2,000 year on year.
Each year, the show generates substantial advertising revenues for the State broadcaster, but RTE doesn't provide a breakdown of advertising revenues generated by each show.
The year under review was also a satisfying one for Duffy from a creative point of view as his book, 'Children of the Rising', was one of the year's best-sellers, with more than 26,000 copies being bought.
