Biography

ABBEY MOLITOR focuses her practice on a range of litigation and regulatory matters, often involving complex financial, accounting, and securities issues. She regularly represents professional services firms — including accounting firms, law firms, and their global coordinating entities — in matters involving pre-dispute counseling and risk management, regulatory proceedings, and litigation in state and federal court. Abbey has substantial experience representing clients in litigation and regulatory matters before the U.S. Securities and Exchange Commission, the Public Company Accounting Oversight Board, and the U.S. Department of Justice. These representations have included issues related to revenue recognition, inventory accounting, earnouts, accounts payable and accounts receivable practices, audit risk assessment and scoping procedures, internal controls over financial reporting, and disclosure obligations. She also has considerable commercial and securities litigation experience, including the representation of both corporate and individual defendants in a multi-billion dollar securities class action. Abbey also conducts confidential internal investigations on behalf of her clients.

Abbey is particularly skilled at working with witnesses in advance of deposition and trial testimony; such representations include working with multiple audit partners at trial and in regulatory testimony and representing several senior executives in high-stakes deposition testimony. Her practice further includes substantial experience developing and executing case strategy, brief-writing (in trial and appellate courts), negotiating and litigating discovery disputes, working with fact and expert witnesses, and managing cases through appeal.

Abbey earned her law degree with honors from The University of Chicago Law School, where she was a Rubenstein Scholar. While in law school, she served as executive topics & comments editor for The University of Chicago Law Review. She received her B.A. in history and political science from the University of Iowa, where she graduated with highest honors.

Prior to joining the firm, Abbey served as a law clerk for the Honorable Steven M. Colloton of the United States Court of Appeals for the Eighth Circuit.
