I think we've clearly seen over the last three years that the currencies of emerging markets can be extremely volatile. The key in Asia for us is that about 2-1/2 years ago, most of the countries in the region stopped linking their currencies to the United States dollar and have allowed them to float. That does mean that currencies will be volatile relative to the U.S. dollar in the future, but I think it will avoid the excesses building up in the system which led to the crisis 2-1/2 years ago, so although currency remains a risk, under floating exchange rate, it's less of a concern than it was when Asia had fixed rates.
