Northern Tier Energy LP (NTI): Northern Tier Energy: Expect A Lower Payout For Q3 2013 - Seeking Alpha

Here is a great article on Northern Tier Energy which appears to be the best of the MLP refiners.  I own the stock myself and may buy more after the current problems have settled down.  The author does a good job of explaining Northern Tier's operation, and the comments of others at the end of the article are helpful also.
