The escrow account holding the Apple tax funds incurred operating costs of €5m from January 2024 to when it was wound up on May 13 this year.
These costs mainly related to investment managers' fees and escrow agent/custodian fees.
The operating costs over the life of the fund totalled €42m, the Office of the Comptroller and Auditor General's annual report states today.
Originally, Apple placed €14.3 billion in the account following the European Commission's 2016 tax ruling which concluded that Ireland had given illegal State aid to Apple.
That figure, arrived at by Revenue, was made up of €13.1 billion in unpaid tax plus interest of €1.2 billion.
In a final ruling last year, the European Court of Justice directed that Apple must pay the money to Ireland, following a series of appeals.
The C&AG said the value of the fund decreased each year from 2018 to 2022, mainly due to declines in the market value of securities and third country adjustments to the value of €455m.
But the net assets of the fund increased by €881m in the years from 2023 to 2025 due to the higher interest rate environment, with the increased income mainly due to reinvesting in assets at higher yields.
