The London contingent: Coveney, Heavey, Breen and Slark
Not included on our main list are chief executives of Irish companies that aren't listed in Ireland.
Dublin-based Greencore was once known as Irish Sugar but its boss, Patrick Coveney, brother of the Agriculture Minister Simon, has focused on the 'food-to-go' market - pre-packed sandwiches, cakes and the like.
The company is in aggressive expansion mode and has recently opened a major new manufacturing facility in the United States.
Coveney's package came to £3.33m (€4.49m at the exchange rates at the company's year end), which would have put him in second place.
Tullow Oil has a secondary listing on the Irish stock exchange and isn't on the ISEQ20.
Last year was one of the most challenging in the company's history amid the collapse in the price of oil. Its chief executive, Aidan Heavey, got £2.84m (€3.85m at year-end rates), which would have placed him fourth.
DCC boss Tommy Breen got €3.83m in 2015, which would have put him fifth after Manifold, Coveney, McCarthy and Heavey. The conglomerate has also been growing in size since divesting itself of its food businesses.
Grafton Group chief executive Gavin Slark got a package of £2.27m (€3.08m at year-end exchange rates). That was down significantly on 2014, when his package exceeded £3m.
He would have been in ninth place on the table, behind Tony Smurfit.
