The list of dividend increases over the past week was dominated by Master Limited Partnerships. Most of the MLPs are pipeline companies, which are engaged in the transportation of oil and natural gas from the source to the final customer. Pipeline MLPs have shown a consistent growth in quarterly distributions as a group, despite the economic turbulence we have lived under over the past five years. This is mostly due to the fact that most pipelines are natural monopolies in a given area, and they typically manage to increase fees each year at least by the rate of inflation. In addition, while prices of the commodities they transport fluctuate on a daily basis, aggregate volumes of oil and gas in the US is pretty stable year over year.
