Mayer Brown bolsters global investigations and enforcement defense bench with former senior DOJ prosecutor Albert Stieglitz. * Author Cynthia Lydia Marbaniang * Published September 23, 2026 WASHINGTON DC - Mayer Brown announced today that Albert "BJ" Stieglitz has joined the firm as a partner in its Global Investigations & White Collar Defense practice in Washington DC. He joins Mayer Brown from Alston & Bird. "BJ is one of the premier investigations and enforcement defense lawyers in the market, bringing an exceptional combination of senior government leadership, domestic and international enforcement experience, and practical business judgment," said Ken Wainstein, leader of Mayer Brown's Global Investigations & White Collar Defense practice. "His experience handling significant fraud and corruption matters on the prosecution and the defense side, coupled with his global perspective from his time inside and outside of government and his strong client relationships, makes him an outstanding addition to our team and further strengthens our ability to advise clients facing their most complex challenges in the US and overseas." BJ advises companies and individuals on internal investigations, government enforcement actions, litigation, and compliance matters involving securities fraud, the Foreign Corrupt Practices Act, and other complex and often cross-border issues. He has advised clients across a broad range of industries, including healthcare, life sciences, energy, retail, financial services, manufacturing, private equity, technology, and transportation. Before entering private practice, BJ spent nearly 13 years with the US Department of Justice, including in senior leadership roles in the Criminal Division's Fraud Section, where he led and oversaw significant fraud and FCPA investigations, tried multiple federal criminal cases to verdict, and was twice awarded the Attorney General's Award for Distinguished Service. He also was selected as the DOJ's first-ever dual secondee to the UK's Serious Fraud Office and Financial Conduct Authority, a role in which he led investigations of a variety of UK offenses, negotiated two UK deferred prosecution agreements, and advised on transatlantic enforcement issues and interagency relationships. "Mayer Brown has built an industry-leading investigations and white collar defense practice, and the opportunity to join it is tremendously exciting" said BJ. "The firm's truly global platform and the outstanding multidisciplinary expertise of its lawyers position it to help clients facing increasingly complex enforcement and compliance challenges in ways that very few firms can. I am excited to join such an exceptional team at this time of strategic growth, and I look forward to contributing to the firm's continued success." "BJ's arrival reflects our continued investment in strategic areas that are increasingly important to our clients," said Andrew Olmem, managing partner of Mayer Brown's Washington DC office. "His distinguished public service background, international experience, and reputation as a trusted advisor make him a tremendous addition to our office and our firm. We are delighted to welcome him to Mayer Brown." Where the legal industry reads first. No spam. Unsubscribe anytime. From Legal Desire Is your firm the one being cited, or the one being skipped?

GlobalCapital's 2026 Americas Derivatives Awards: the winners.

GlobalCapital's 2026 Americas Derivatives Awards: the winners. GlobalCapital September 18, 2026 03:04 pm The Americas derivatives market gathered in New York to recognise and celebrate outstanding achievement across the industry. The Americas derivatives market got together on Thursday evening at New York's Metropolitan Club to celebrate the institutions that made an impact over the past year. This year's Americas Derivatives Awards winners recognised achievement across the period April 1, 2025 to March 31, 2026 - a stretch in which volatility stemming from the Middle East, rising interest rates and a shifting geopolitical backdrop tested nearly every market participant. Across 60 categories, over 100 institutions were shortlisted, and 90 pitch meetings were conducted over the course of this year's awards judging process. GlobalCapital is grateful to every organisation that took the time to meet Bank Climate Advocates and make the case for their business. If there was one thread running through this year's pitches, it was purpose. Firms were focused on solving client problems in real time, with hedging and liquidity solutions the common language of an industry navigating uncertainty. Picking winners from that field was no easy task. Below is just a flavor of the night's headline results. The full nominee shortlists and the winners can be found below. The night belonged to Bank of America, which claimed both the Americas Derivatives House of the Year and the Global Derivatives House of the Year for good measure. The bank also took home the titles for the Commodity, FX, Inflation, Equity and Interest Rate Derivatives House of the Year. The bank stood out for helping clients navigate real geopolitical and market disruption, from commodity supply shocks to currency volatility, while backing that resilience with deep structuring expertise and the scale to handle the market's most complex risks. The night in photos can be seen below: On the legal side, Mayer Brown extended its own run, becoming Americas Law Firm of the Year for a fifth consecutive year while also picking up US Law Firm of the Year - recognition for a firm that keeps positioning itself exactly where the market is heading next. Elsewhere, Santander made it three years running as Latin America Derivatives House of the Year, RBC Capital Markets was named Canada Derivatives House of the Year, and Borden Ladner Gervais took home Canada Law Firm of the Year. Behind every one of these wins sat months of groundwork - market soundings, written submissions and wide-ranging pitches gathered from across the Americas derivatives landscape, all weighed carefully by its editorial panel before a single name was chosen. Thank you to everyone who gave their time through submissions and pitch interviews this year. And to all of this year's nominees and winners - many congratulations. Finally, none of this would have been possible without the support of its event partners. Platinum event partners GoldenTree Asset Management: GoldenTree is an employee-owned, global credit asset manager founded in 2000 by Steven Tananbaum, with a footprint spanning high yield bonds, leveraged loans, private credit, distressed debt, structured credit, emerging markets, real estate, private equity and credit-themed equities.
