Firms run by RTÉ's top earners sitting on substantial cash piles
Seven of RTÉ's top 10 earning presenters use companies to contract out their services to the national broadcaster.
There are a number of potential benefits to doing this, which regular RTÉ employees do not enjoy, such as greater control over tax and pension arrangements.
Accounts show some presenters are sitting on large cash piles, while others have chosen to take out the bulk of what RTÉ pays their companies.
Top earner Ryan Tubridy's Tuttle Productions Ltd is the company RTÉ paid €495,000 for the 'Late Late Show' presenter's services in 2015.
The 44-year-old and his mother Catherine are the company's directors.
There is no breakdown of what he personally took out of the company as a salary.
Overall director remuneration topped €1m in a 28-month period, according to the two most recent sets of accounts filed by the firm. Directors' emoluments amounted to €473,328 for the 16 months up to December 2016, and €590,345 for the 12 months up to August 2015.
