Ireland has invested Apple’s back taxes into low-risk, highly rated bonds, according to a new report. The move is an effort to preserve capital amid an ongoing appeal, which could take several years to resolve.

Apple has agreed to pay French authorities around $571 million in back taxes, according to new reports.

Apple today confirmed the deal but did not disclose the sum itself. The agreement comes after a multi-year audit into Apple’s accounts by the French tax administration.
