There's a very simple point to make here, which is to do with your ability to diversify risk within your own portfolio, because you have lots and lots of different investments. If you are quite a small entity, one way of coping with risk is to have lots and lots and lots of very small investments so they don't all fall over at the same time, whereas if you had some chunkier investments, obviously your risk exposure would be a lot higher.
Maybe it would be wise of me not to mention who they are, but there was a small European DFI who was told to go out and take more risks and do more business in the harder places. They lost a bunch of money. They turned around to their government and said they needed some money, and the politicians said, “What are you doing? You're not supposed to be losing money.” So this is something that definitely can happen.
If the reality is that a Canadian DFI has quite a limited risk-bearing appetite, then this is maybe where partnership can come in. Let's say, around the world right now there are a dozen universities and start-ups working on small-scale, low-cost desalination technologies. It's the perfect thing for a DFI to put its money into, because discovering which of these technologies works would be of fantastic benefit to the whole world. You could try and commercialize a dozen of these technologies, and if you did all that, you'd probably, across the portfolio, stand a large risk of losing a lot of money.
The Bill & Melinda Gates Foundation, however, might be really keen to see that sort of desalination technology happen and offer to put up some first loss grant capital so that if things do turn out toward the bad side of things, you're not left wearing all the losses. If you are thinking about ways of doing more risky things without exposing a relatively small entity to too much risk, then finding people to work with who might be able to put up money to help with that might be the way to go.
