Banking and finance

Within: Banking and finance

Mayer Brown's position in the banking sphere is reflected by the fact that it acts for many of the world's largest banks; it also has an outstanding reputation among borrower clients. The arrival of Doo-Soon Choi from Ashurst in 2016 has strengthened the firm's offering in relation to complex, cross-border multi-tiered financing transactions. Choi's experience spans multiple sectors, including real estate, healthcare, mining, and oil and gas. In addition, the firm further bolstered its practice recently, by hiring Hallam Chow from White & Case. Chow has particular experience in acting for Chinese banks and state-owned enterprises (SOEs) on innovative, landmark inbound and outbound transactions. Richard Stock heads the team, which also includes Fanny Wang and Francis Chen. Reflective of the firm's ability to draw upon expertise across practices in particularly complex matters, in 2017 Choi and capital markets specialists Jason Elder and Thomas Kollar assisted Indika Energy with a $575m senior notes issuance as part of a larger 'bridge-to-bond' acquisition financing. Wang was also the lead adviser to Bank of China (Hong Kong) on a $688m syndicated loan facility to Pace Ascend to part-finance the acquisition of New Grade Investments from Greater Honour, a wholly-owned subsidiary of The Wharf (Holdings). Another highlight involved acting for United Overseas Bank on the provision of two bilateral loan facilities (total value $206m) to a subsidiary of a real estate investment fund for the purpose of acquiring properties in Hong Kong for redevelopment into commercial premises. Associate Dion Yu is recommended.

Hong Kong: Capital markets

Capital markets (debt)

Within: Capital markets (debt)

Mayer Brown's clients turn to the firm for their most structurally complex transactions, and matters involving intricate subordination and intercreditor issues. Jason Elder heads the team, which has strong New York, English and Hong Kong law capabilities. It serves clients from throughout Hong Kong and the PRC, as well as those in emerging markets across the Asia-Pacific region. The firm has a particularly outstanding reputation for high-yield debt transactions; Thomas Kollar has been a major figure in the Asian market for more than 15 years, and also has a wealth of experience executing a sizeable number of high-yield transactions globally. Beyond high-yield transactions, the group covers other types of matters, including investment grade and hybrid securities offerings, as well as structured debt transactions. It also has stellar credentials in the corporate trust and agency arena, which involves acting for trustees and agents on bond issuances, liability management exercises and restructurings. Illustrative of the firm's high-quality work, in 2017 Elder and Kollar were among the advisers to PT Indika Energy as issuer on a $575m bond offering, which was part of a larger bridge-to-bond acquisition financing transaction for the client to increase its stake in Indonesia's third-largest coal mine. Kollar and Elder were also part of a cross-office team, which acted for the joint lead managers and bookrunners in a £2.5bn dual-tranche offering by the Democratic Socialist Republic of Sri Lanka. Other clients include The Bank of New York Mellon, China State Construction International Holdings and Sinochem Offshore Capital. Derek Tsang left the firm to set up his own private practice in April 2018.
