I don't want to give you a non-answer here, but I think what's important is that, for any DFI, there need to be clear guidelines and standards for how any investment is made and what the impacts of those particular investments are from a social, environmental, and financial perspective.
Insofar as you're trying to crowd in a host of other partners and investors, I wouldn't discriminate against any particular group, so long as they're able to pass our diligence process and demonstrate that they are, indeed, a well-appointed partner for investment in a particular case.
I realize that may sound like a non-answer, but I think it's, perhaps, too specific a question to answer in one fell swoop.
