Back on March 15, the Federal Energy Regulatory Commission shook up master limited partnerships (MLPs) and their investors by deciding that income taxes would no longer be factored into the cost-of-service-based tariff rates of MLP-owned pipelines. We said then that there was no need to panic. In part, this was based on the view the FERC policy wouldn’t affect as much of the industry as some worried it would. But more importantly, our soothing message was tied to the fact it would take a long time for this to play out. It looks like we were right to have some confidence. Today, we explain why the commission’s July 18 vote on a topic as nerdy as “accumulated deferred income taxes” can warm the hearts of MLP investors.
