As the Deputy will be aware, under the relationship framework the State does not have a role in the day-to-day operations of the banks in which it holds investments or their management decisions regarding commercial matters. Hence, decisions around redundancies, appropriate staffing numbers and determining the skill sets required across each institution is a matter for each bank's executive management team and the relevant staff, in consultation with their union representatives.
With regard to AIB specifically, the bank have informed me that in the period July 2012 to December 2016, over 2,600 employees in Ireland and the UK left the organisation under the terms of the Voluntary Severance scheme.
The costs associated with the Voluntary Severance scheme in respect of the relevant period are detailed in the bank's annual reports, which can be found here: https://aib.ie/investorrelations/financial-information/results-centre/2016.
