Jim Cramer told fans of his “Mad Money” TV show that not all master limited partnerships (MLPs) are created equal. He said he favors high yielding, energy-based MLPs, but he sees trouble ahead for many of them. He explained there are two classes of energy MLPs. The first, are ones that make money from gathering and processing of oil, and the second is those that make money off of transporting oil. Cramer said the latter is safe, but the former could be heading for trouble. He said Williams Pipeline (WMZ), Atlas Pipeline (APL) and DCP Midstream (DPM) are all at risk from falling oil and need oil at $75 a barrel to make money. Due to the sharp drop in oil prices, Cramer says their dividends could be a at risk. He said Crosstex Energy (XTEX) is an example of what can happen when an MLP cuts its dividend. Cramer told viewers that he continues to like energy play Kinder Morgan (KMP), but he made a mistake in recommending Atlas Energy Resources (ATN).
