"We are pleased to announce another quarter of improved financial results,” said Clark C. Smith, chairman, president and chief executive officer. "Our Global Marine Terminals segment reported a contribution for the first time from our recent acquisition of a 50% equity interest in VTTI that closed early in the first quarter of 2017, which drove our year-over-year improvement in performance. This segments legacy assets continued to benefit from high utilization but were adversely impacted early in the quarter by operational issues experienced at our South Texas facility. Our Domestic Pipelines & Terminals segment saw strong contributions from growth capital investments that drove higher pipeline transportation and storage revenues during the period. Our Buckeye Merchant Services business continues to benefit from effective supply chain management efforts, driving solid results that were partially offset by compressed rack margins as a result of warmer-than-expected weather conditions during the quarter."
