Rough winter weather, especially in North Dakota’s Bakken shale, caused the results of ONEOK (NYSE: OKE) and its master limited partnership, ONEOK Partners (NYSE: OKS), to come in a bit under expectations. That said, the MLP still delivered year-over-year growth in the fourth quarter thanks in part to higher processing fees, which flowed down to ONEOK’s results. Overall, the midstream general partner’s cash flow available for distributions rose 2.7% year over year.
