I would love to answer that question as directly as possible, but again, not having done a review in this area, I would be speculating as to why that might be happening.
I think the first thing I would want to know is specifically which exception is being invoked to allow that to happen. If it's because of a low dollar value, I'll note we wrote a paper on economies of scale and fiscal efficiency associated with when one should direct a contract for low dollar value threshold procurements. If it's for the other three exceptions, being that there's only one supplier, I think it would be troubling to learn that the frequency with which that exception is being invoked has escalated. However, again, I don't know that to be a fact.
