The Deal reported BSF Corporate represented NuStar Energy, an oil and gas pipeline and storage company, in connection with the signing of a proposed formation of a joint venture with Lindsay Goldberg, a New York based private equity fund, to hold and operate NuStar's asphalt refining assets. The deal is expected to close by late summer or early fall, and will allow NuStar to deleverage and focus as a business on its core pipeline business.
