Practice/Organization Description

Accounting expert Dr. Barry Jay Epstein, CPA, CFF, is a practicing accountant and respected author of many books and articles on Generally Accepted Accounting Principles (U.S. GAAP), International Financial Reporting Standards (IFRS), and Generally Accepted Auditing Standards (GAAS).

Dr. Epstein served as the author of The Handbook of Accounting and Auditing, published by Thomson Reuters, from 1998 through 2013. He served as the lead author of 26 annual editions of Wiley GAAP (1985 through 2010) and 14 annual editions of Wiley IFRS (1997 through 2010), all published by John Wiley & Sons.

Dr. Epstein concentrates his forensic accounting practice in the following areas:

- White collar defense

- Financial reporting fraud and securities litigation

- Accountants' liability and accountant malpractice

- Generally Accepted Accounting Principles (GAAP)

- Generally Accepted Auditing Standards (GAAS)

- International Financial Reporting Standards (IFRS)

- International accounting convergence (GAAP and IFRS)

- Sarbanes-Oxley corporate governance matters

Dr. Epstein has consulted and/or testified as an expert witness for plaintiff and defense attorneys in more than 140 cases. He has done substantial work for federal and state regulatory agencies.

As an international accounting expert, Dr. Epstein assists international corporations, financial analysts and professional investors in interpreting financial statements and reports prepared in accordance with IFRS.

He has advised U.S. and foreign-based professionals, and business entities that are involved in—or are contemplating—joint ventures, new vendor or customer relationships, and establishing subsidiary operations, to educate them regarding the effects of financial reporting under IFRS.

Dr. Epstein analyzes the selection and application of accounting principles to look for "red flags" that may emerge when international financial statements prepared in accordance with IFRS are reconciled with U.S. GAAP. Areas of possible exposure are identified, such as those resulting from alternative use of fair values, and accounting for financial instruments and hedging transactions.
