Within: Capital markets: debt offerings

Vinson & Elkins LLP is hailed for its ‘responsive and practical approach’ and ‘coordinated Houston and UK offices, which are a great asset in cross-border transactions’. An undoubted leader in the energy arena, where it is widely regarded as ‘a top choice for issuers’ counsel’ but also acts for underwriters, the group’s robust experience in transport, financial services, real estate and telecoms matters also deserves mention. Practice co-head David Oelman is a sought-after name, who recently acted with Alan Beck and firm chair Mark Kelly in advising Anadarko on its $3bn offering of senior notes. Oelman and Beck teamed up again to assist Plains All American Pipeline with its $1bn investment grade offering of senior notes. Michael Harrington has ‘deep expertise in debt deals’ and acted alongside Kelly to advise LyondellBasell Industries on its €750m offering of senior notes. Matthew Strock jointly leads the Houston-headquartered team together with Oelman.
