No.
Resolution actions are paid for from the Credit Institutions Resolution Fund, which is funded by levies on credit institutions. There is no direct taxpayer cost.
This case has been over 4 years in the making. The appointment of a liquidator is the right action to contain the issue and protect members savings, which in the CBIs remit.
The appointment of a liquidator will result in a short resolution timeframe. It should cost less than a disorderly wind-down over years which will probably result in an insolvent situation which requires a liquidator anyhow. Or funding from the CBI which leads to a spread to the tax payer.
