This is a temporary account as it operates until the completion of a transaction process, which is implemented after all the conditions between the buyer and the seller are settled.
The European Commission had ordered Ireland to collect the money after concluding that two Irish tax rulings allowed Apple to pay less tax than other businesses - thus giving them an unfair advantage.
"We have now reached agreement with Apple in relation to the principles and operation of the escrow fund", Irish Finance Minister Paschal Donohoe told reporters.More news: Net Neutrality vote must wait until conclusion of comment investigation, Schneiderman says

What did Apple do exactly to warrant a payment as big as €13 billion?
While the appeals are still ongoing, the European Commission ordered Ireland to begin collecting Apple's taxes on January 3, and the organization referred Ireland to the EU Court in October for failing to comply with the deadline.
Now it appears Apple and Ireland have agreed to cooperate, and pay $15.4 billion to the Irish government, all while however still continuing litigating the case.
Apple believes that the ruling will be overturned in time and that it's acted in accordance with the law.
KitGuru Says: Apple may start setting the money for this aside soon, but it seems clear that it still wants to get out of it.
