What I can describe is the trend, and the trend indeed is to lower the rates of corporate income tax. And that's an OECD recommendation. To favour investments you need to have reasonably low rates for corporate income tax, and on the other hand to improve compliance. This is why we, the OECD member countries, have launched this initiative. The U.K. is leading this project, supported by Germany, France, Canada, Australia, New Zealand, and many other OECD countries to fight double non-taxation, because we fear that this will undermine the very existence of corporate income tax and we will have this distortion among domestic companies and international companies. It's better to have low rates but make sure that their effective tax rate is comparable to the statutory tax rate.
