Mr. Diarmuid O'Flynn:

It is dated December 2010 and it states:

I am advised that the Central Bank (the Bank) may decide that it is appropriate to provide liquidity assistance to the EBS Building Society. The amount to be advanced and the terms and conditions of any lending are to be decided by the Bank.

It is the policy of the Government that the Bank should not incur a loss in the provision of emergency liquidity assistance to support Irish credit institutions. Accordingly, if any such loss is in prospect the Government will [there is a redacted element and then the note continues] provide for the Bank to receive payment to make good any shortfall.

That is quite literally the promissory note. It was based on the premise of emergency liquidity assistance.
