Matt has been significantly involved in numerous complex chapter 11 cases and non-judicial restructurings, both U.S. and cross-border matters, including most recently acting as counsel to Momentive in its landmark chapter 11 cases, Core Media, the owner of American Idol in its complex cross-border filing and the COFINA Agent in the title III cases for the Commonwealth of Puerto Rico. He regularly represents hedge funds, such as Centerbridge Capital, TPG Special Situations, Silver Point Capital, Black Rock and Twin Haven Capital, in all aspects of judicial and non-judicial restructurings. He also regularly represents investors seeking to acquire assets or businesses from companies operating in chapter 11.

In March 2009, Matt was recruited to serve as Chief Legal Advisor to the Obama administration’s Task Force on the Auto Industry. This cabinet-level Treasury Department task force was assembled to help develop the overall strategy to restructure and recapitalize General Motors Corporation and Chrysler LLC, a strategy which resulted in the groundbreaking legal proceedings that implemented a comprehensive financial solution for both companies. The Auto Team conducted complex negotiations with all major constituents of both companies, including Fiat SpA (which now runs Chrysler), the United Auto Workers and major creditors of both auto makers under a compressed timeline set by President Obama. 

In 2014, Matt was named a Law360 MVP in Bankruptcy and was selected by Turnarounds & Workouts as an "Outstanding Restructuring Lawyer," an honor he won in 2009 as well. In 2015, T&W also recognized Matt for his lead role representing the Debtors in the precedent-setting restructuring of Momentive Performance Materials, which was featured on the publication’s listing of the most successful restructurings of 2014. He was included on the Financial Times "US Innovative Lawyers of 2010" report and profiled among its 10 featured attorneys. In 2009 he was named "Dealmaker of the Year" by The American Lawyer. Since 2003 he has been recognized by Chambers and Partners as one of the leading restructuring attorneys internationally and in the U.S. In addition, Matt has been listed in Lawdragon 500 Leading Lawyers in America, the International and Domestic Who’s Who Legal, and is recognized in The Best Lawyers in America. He is also consistently recognized in Benchmark Litigation.
