In our program we fund a project consortium in each case. The government money, which is the money we provide into that project consortium, is on average across our portfolio 33%. It's capped at 33%; in practice, it's actually about 29%. It's about a two and a half to one leverage within the project. That's in the SD tech fund, which is the $590 million fund that's been in place since 2002, with successive recapitalizations.
In the NGBF, the next-generation biofuels fund, it's similarly one-third government money through SDTC and two-thirds from the private sector in each case.
In the SD tech fund, we track follow-on financing that comes into our companies after our money, and we then see a further leverage of eight to nine times capital coming into those companies on top of our money. It's quite a significant amount of private sector money, which actually exceeds the two and a half to one, and then more money coming in afterwards.
