Firm Profile > Proskauer Rose LLP > London, England

Proskauer Rose LLP

Private funds Tier 2

Strong expertise in the secondaries market is the hallmark of the private funds practice at Proskauer Rose LLP, which is led by 'trusted adviser' Nigel Van Zyl. In addition to assisting clients with fund restructurings and acquiring and selling portfolios, the firm's fund formation instructions constitute approximately 65% of its private funds offering. While some of these are from large, well-established managers, the team is becoming a particular favourite of first-time fund manager clients (especially those that have spun out from prior firms). Although GP-side work forms most of the practice, the firm advises over 100 Limited Partners (LPs) globally, ensuring a breadth of market knowledge. Kate Simpson is a name to note, having led on a structured  transaction for Investcorp involving the sale and transfer of $185m worth of assets to a new fund. Also recommended for his specialist secondaries expertise is Bruno Bertrand-Delfau. Although Andrew Shore departed for Kirkland & Ellis International LLP in February 2019, Proskauer Rose LLP moved to rebuild with the hire of Leith Moghli from Reed Smith LLP in August of the same year. Brendan Gallen joined as special counsel from Fried, Frank, Harris, Shriver & Jacobson LLP in the same month, while Warren Allan, who focuses on private funds, including private real estate funds, joined from Stephenson Harwood in September 2019.

High yield Tier 3

'The high yield team in London stands out for its quality of service and expertise and we regularly work with the firm on some of the largest transactions in Europe', says a client of Proskauer Rose LLP. The firm has an integrated high yield debt practice in London and the US, and it advises leading issuers, underwriters and global financial institutions on some of the biggest deals in the market. In 2018, this included one of the largest high yield bonds by a Spanish issuer. 'Top-class lawyer' Maximillian Kirchner leads the firm's European high yield practice and clients remark that he is 'very commercial and efficiently manages complex and innovative deals on tight timelines'.

“Proskauer has a premier practice in London advising asset managers on European, US and Asian high yield transactions, and it has significant experience with complex deals involving multiple jurisdictions.”

“Proskauer’s London office has a top-notch team with significant industry expertise, in particular based on the firm’s strength around US-style high yield bond execution.”

“In contrast to other firms, Proskauer has a boutique approach with partners that are ‘hands-on’ and very involved in the transaction from kick-off to closing of the deal. In the high-yield space, it provides the best value for money.”

“Maximilian Kirchner has a very deep understanding of the high yield product and is exceptionally hardworking and responsive. The quality of his work is outstanding, and he is very efficient when it comes to cost control.”

“In addition to his excellent skillset in executing complex high yield bond deals, Maximilian Kirchner has the ability to provide top-notch guidance during the structuring and execution of deals.”

“Extremely hard working, always available and very responsive. The firm has deep capital markets knowledge and insight that is helpful in negotiations because the lawyers know the details of previous deals in the market, which ensures negotiations move along quickly and on the best terms available.”

“The London team provides top-quality service for a reasonable price. It is one of our favourite law firms to work with on complex cross-border capital markets or high yield matters, and we have built a long-standing relationship and trust with them.”

“We have found the Proskauer team, in addition to merely being competent, to be both exceptionally creative and commercial when it comes to approaching deals, and willing to work constructively to overcome challenges.”

“Max Kirchner is the partner with whom we have worked most closely. He is a resourceful lawyer with a strong commercial sense, and has been a valuable source of counsel to us in thinking about deal structuring. He has an excellent command of high yield debt and other leveraged finance products.”
