As I have said, this was before my time when there was a big public debate, resulting in the White Paper on public transport. The Government, and I suppose this House, reached a certain long-term view about how one should fund public transport, and it was as what I had articulated in my reply just now. The intention was that the Government will pay for the infrastructure, that means, the tracks, the viaducts, the underground tunnels, plus the first set of operating assets, which include the trains. Subsequent train operations, which include future replacement of the operating assets, have to be paid for from the fare revenue plus non-fare revenues, which include advertising. And if we achieve that, then the operating subsidy would have been zero. But now, it is more like more than 30%.
