Nine months ago the index, according to BAC/ML estimates for each company, had an expected distribution growth rate of just under 7%. Since then one of its largest components, KMP, has been removed and replaced with slightly faster growing companies. However, due to the conditions in the energy industry, distribution growth rates have been lowered. I haven't run the numbers yet, but I would suspect the index growth rate has been lowered to approximately 6% with the near term bias for additional declines. A 2X the index growth rate that still leaves dividend growth (really interest) of near 12%. Another caveat is that if short rates rise the cost of leverage will also rise, eating into the return. I do believe that the cost is born by the NAV and not the dividend, however. So, barring a true disaster in the MLP space (which could, of course, occur) dividend increases should remain somewhere near the 10% range (assumes 5% CAGR on the index).
