It's a three-year cycle and then out at ARPA–E, whether for program leaders or projects. What does that mean for the ARPA–E team in the long term?
There's some flexibility in the statute [that set up ARPA–E]. It's a director's discretion to have some flexibility. You don't want to make that rule hard and fast because of discontinuity of programs and all that. That discretion is there in the statute and I'll use it when I need to. But I think there's an understanding in ARPA–E that once you've done three years, you ought to move on.
