Once fee based prices mid-streams get for their services are re-negotiated to a much lower rate due to the collapse of the budgets of the upstream companies DCF for mid-streams will be hit and hit hard .
You'd have to be a fool without equal to believe these low O&G prices won't hit the mid-stream MLPs eventually . Their current high valuations will suffer much like the upstream space has already seen . If you don't believe me check out how there's an approximate 6 month lag between the fall in value of upstream versus the fall in value of service providers and mid-streams .
We are just beginning to see this happen with companies like OKS and it will hit others eventually .
