Accounting & Financial Reporting Litigation

Sign Up for Publications

Financial statement reporting, accounting, and auditing is highly specialized and technical.  Fluency in these fields is usually believed to be found only among trained accountants.  Increasingly, however, modern commercial legal disputes, investigations, and regulatory matters arise from or are driven by accounting and reporting issues, and therefore victory for clients is often a function of their counsel’s grasp of these specialized subjects.  

Financial reporting cases frequently arise from company failures or corporate scandals.  Potential defendants like the company’s auditors blame management or other financial service providers.  Applying the professional standards to determine liability, allocating harm among joint tortfeasors, and simultaneously navigating the potential defense of in pari delicto requires deep experience and nuanced advocacy.  Our firm has decades of experience and more than fifty partners, associates, and counsel from around the globe who specialize in accounting and financial reporting litigation, including former qualified accountants.  We understand the intricacies and methodologies of this area, and the technical standards of the profession and regulatory systems that govern them.  

Several of our partners worked for or represented the Big 4 accounting firms before joining our firm.  Because of our subject-matter expertise, our size, and our effectiveness in court, there is no law firm better equipped to hold the global accounting firms accountable.  We have represented clients in some of the largest national and international accounting scandals of the past two decades, including Enron, Parmalat, MF Global, and Refco.  The accounting firms know what we can do in court; they would rather avoid us.  We have the skills needed to take an audit malpractice case from an early investigation all the way through to a jury trial, if necessary, and we are one of the few law firms in the world to have done so and won.  Because of our reputation, we have been able to help clients obtain favorable outcomes outside of court, including several record-setting nine-figure settlements. 

A substantial part of our practice also involves defending accountants, accounting firms, audit committees, officers and directors, companies, and financial institutions against accounting-related claims in court or investigations of all kinds.  Our experience ranges from small regional cases to multi-billion dollar international and cross-border investigations and disputes.  And we advise clients in non-litigation settings as well, such as helping them to address complicated financial reporting, accounting, and auditing challenges (including under complex interpretations of GAAP, GAAS, IFRS, and ISA), navigate thorny conflicts with outside auditors or regulators, conduct internal forensic accounting investigations, or analyze and mitigate litigation risk in the context of business transactions and investments.  Because our firm handles plaintiff, defense, and regulatory matters, we have been able develop strong relationships with some of the most brilliant and trusted independent experts in these fields, working with them to help address the unique needs of our clients, in or out of the courtroom. 

The highly technical world of accounting, auditing, and financial reporting is no place for beginners.  We have deep domain knowledge and experience – an acumen uncommon among commercial litigators and white-collar practitioners.  Combined with our large talent pool, global resources, and advocacy skills, there is no law firm in the world better qualified to assist clients in any litigation or investigatory setting involving these subjects whether defending these claims or pursuing them.
