Mr. John McCarthy:

We have a number of mechanisms through which we can get data on that. The service indicator reports, which local authorities publish every 12 months, provide data. We updated that figure - maybe it is more relevant and more recent - for the purposes of the capital funding we are now making available for voids quite recently. The service indicators for 2012 showed us there were approximately 4,000 units vacant, which is of the order of approximately 3% of the stock. In the more recent survey we did for the purposes of the capital programme for investing in voids, the information we received from local authorities suggested there were just over 3,000 voids capable of being returned to productive use, so it is in that range of 3,000 to 4,000.
