Mr. Mark Griffin:

I might come in on that, although Mr. Mulligan is actively dealing with the IRP. In summary terms, there can be a withholding of the subsidy, and when the milestone is met, there is a recalculation of that milestone subsidy to see whether reductions should be made, having regard to any relief to which the contractor might be entitled under the contract. There are also performance credits whereby, if certain operational requirements are not met, there can be a deduction or a withholding of subsidy. The description of the remedial planning process will probably give a good understanding of exactly what we are doing in terms of due diligence on this.
