Audit Advisor, Litigation Support (Expert Witness) & International Speaker

David R. Hancox, CIA, CGFM

I've worked for 41 years in the audit field with expertise in performance, compliance and financial auditing, and best practices in performing these audits. Over the course of my 37-year career in the New York Comptroller's Office, I served as both the Director of State Expenditures and Director of State Audits. As Director of State Expenditures, I led a 115-person team responsible for auditing more than $70 billion in transactions annually. There were over 100,000 transactions per day.

I transformed this unit from a labor-intensive, clerical audit operation to a modern, risk-based professional audit unit, using the latest audit techniques, including advanced data analysis and data mining techniques, to find fraud, waste, and improper transactions.

My team and I also revamped the State Comptroller's audit process over the State's $50 billion in Medicaid expenditures by bringing in advanced audit tools that increased our cost recovery efforts.

Several of the largest law firms in the world have also retained me as an expert witness. In one case, I testified in a multi-defendant arbitration before three former federal judges that resulted in a $1.5 billion award for the companies on whose behalf I was retained. My work was based on the management practices and internal control systems implemented by the defendants.

Government Performance Audit in Action – 5th Edition

Martin Ives, CPA, CGFM &
David R. Hancox, CIA, CGFM

Because we have extensive experience in performance auditing, we emphasize both theory and practice. Eight of the 15 chapters are devoted to performance audit of specific governmental functions and programs. The book is full of illustrations drawn from actual audits. That’s why we call the book …Audit in Action.

Because we are publishing this book ourselves, we can customize it to your needs. We will sell either the entire book or any chapters you wish. For example, if you teach a course in financial auditing and want to give your students a general understanding of internal auditing, we can put to together, say, five or six chapters to cover the subject.

Although we emphasize governmental auditing, the concepts and practices are readily transferable to the not-for-profit and business sectors, particularly if you select specific chapters.
