M&A/corporate and commercial > Private equity buyouts Tier 5

Arnold & Porter focuses primarily on middle-market transactions, representing clients both on the buy and sell-side. The practice works on a variety of transaction types, including public and private buyouts, asset acquisitions, go-privates, exits, and early-stage venture capital investments. More complex work includes distressed acquisitions and continuity advice to newly-public portfolio companies. The practice is jointly headed by New York-based partner Stephen Koval, alongside Andrew Varner and Kevin Lavin in the Washington DC office. The team's wider capabilities support the private equity practice, with partners able to provide regulatory and tax-related advice on transactions, as well as act in difficult cross-border deals thanks to the geographic spread of the practice.

Tax > US taxes: non-contentious Tier 5

Arnold & Porter has core strengths in tax issues around the formation of public and private REITs, compensation and benefits and the tax treatment of non-profit organizations. Practice co-head Laurie Abramowitz in New York handles transactional tax work in the life sciences and financial services sectors, while joint practice head James Joseph specializes in advising tax-exempt organizations, including public charities and private foundations. Also recommended are Joseph Howe, an expert in REIT taxation, and San Francisco-based Ben Berk, who has broad expertise in corporate and partnership taxation. All named lawyers are based in Washington DC unless stated otherwise.

Finance > Restructuring (including bankruptcy): corporate Tier 6

Arnold & Porter's restructuring practice in Chicago is led by Michael Messersmith. Focusing on ad hoc groups of lenders and bondholders, his team is especially respected for the representation of buy-side lenders in syndicated loan restructurings. Other key attorneys work out of the Washington DC and New York offices. Jonathan Levine joined in February 2019 from Morrison & Foerster LLP and brings his expertise in complex Chapter 11 reorganizations and out-of-court restructurings. A chief highlight of 2019 was the victory for an ad hoc group of lenders in the restructuring of iHeartMedia.

Banking and finance > Banking and finance Tier 3

Arnold & Porter continues to be recognised for its standing in bank regulatory matters, along with structured finance, securitisation and derivatives. Its connections to prominent members of the banking and finance community, stem in part from its history in sovereign debt restructuring where it has worked with a multitude of ministries of finance and central banks. The firm represents a wide range of Latin American financial institutions along with the Latin American arms of international banks and also advises a large number of sovereign states and state-owned enterprises. It remains closely associated with distressed debt, infrastructure finance and financings led by agency lenders and DFIs; and is also frequently engaged on regulatory matters linked to licensing issues and acquisitions of US-based financial institutions. Whitney Debevoise has a close association with Brazil, including major banks there, along with El Salvador, Panama and Honduras; he has an excellent record in sovereign and corporate debt restructurings, structured finance and derivatives transactions. Gregory Harrington is also recognised for his Brazil experience and has close relationships with Brazilian banks and the Brazilian arms of international banks; in addition, he is noted for SEC reporting matters. Beyond Brazil, he represented Camposol (Peru) in a $200m senior secured term loan facility from Banco Santander and Coöperatieve Rabobank. Senior counsel Neil Goodman has wide ranging experience in Latin America, covering both capital markets and debt financing transactions; he frequently advises a number of sovereign states.
