When we started off with the Bill and Melinda Gates Foundation, we were originally targeting entering 21 new countries. At the time we were in three of them, so we had a whole process to try to evaluate how we can get into those countries.
Since then, we've learned a lot. Each country, unfortunately, is pretty well unique because there's a series of regulatory issues and a series of foreign direct investment restrictions. There are all sorts of combinations and local market practices that make it exceedingly difficult to do that.
At this stage, we do not have funding to enter new countries. If a donor came to us and said they'd like us to consider such-and-such a country, we'd seriously look at that and try to develop it. It's a question of a combination of funding, new distribution technologies and approaches—think mobile phone—and covering off a large number of countries. We're planning to ramp that up big time over the next couple of years. As well, it's a question of the will to get in there and do it.
