This part was scary though : "NGL Energy Partners LP's (NGLEP) B1 Corporate Family Rating (CFR) reflects its high financial leverage, heightened volume and counterparty risk following a collapse in upstream drilling activity and the bankruptcy of its largest shipper on the Grand Mesa Pipeline. Tight capital market conditions have raised its cost of capital.".
Did you read that? It's damn negative. Mentions two dangers I've often pointed out, high leverage and counterparty risk. NGL's SEC filings mention those too.
