Definition of Forensic Auditor
TALLY STICKS
Someone who can look behind the
facade--not accept the records at
their face value--someone who has a
suspicious mind that the documents
he or she is looking at may not be
what they purport to be and someone
who has the expertise to go out and
conduct very detailed interviews of
individuals to develop the truth,
especially if some are presumed to
be lying.
Robert G. Roche, a retired chief of the IRS Criminal Investigation
Division of the IRS

Narrow Approach
Narrow vs. Broad Definition
• Narrow: Fraud Detection Is Major Area.
• Broad: Employed to seek, interpret, and
communicate transactional and reporting
event evidence in an objective, legally
sustainable fashion, not only in situations
where there are specific allegations of
wrongdoing, but also in situations where
interested parties judge that the risk of
loss from wrongdoing is such that proper
prudence requires legally sustainable
evidence to support the conclusion that
no wrongdoing is occurring (James
Edwards).

Forensic accounting is the application of
accounting, tax, auditing, finance,
quantitative analysis, investigative and
research skills, and an understanding of
the legal process for the purpose of
identifying, collecting, analyzing, and
interpreting financial or other data or
issues in connection with:
Antitrust matters
Insurance claims
Accounting
1) Litigation services: providing assistance
for actual, pending or potential legal or
regulatory proceedings before a trier of
fact in connection with the resolution of
disputes between parties, or
Analyses
Damages

2) Non-litigation
services:
performing
analyses or investigations that may require
the same skills used in 1, above, but may
8
not involve the litigation process.

One Small Clue
Forensic Accounting Factors
• Time: Forensic accounting focuses on
the past, although it may do so in
order to look forward (e.g., damages,
valuations).
• Purpose: Forensic accounting is
performed for a specific legal forum
or in anticipation of appearing before
a legal forum.
• Peremptory: Forensic accountants
may be employed in a wide variety of
risk management engagements within
business enterprises as a matter of
right, without the necessity of
allegations (e.g., proactive).
----------------------------------------------With a single clue a forensic
accountant can solve a fraudulent
mystery.

A former Scotland Yard scientist tried to create
the world’s biggest fraud by authenticating $2.5
trillion worth of fake U.S. Treasury bonds.
When two men tried to pass off $25 million
worth of the bonds in Toronto in 2001, a
Mountie noticed the bonds bore the word
“dollar” rather “dollars.”
Police later raided a London bank vault and
discovered that the bonds had been printed with
an ink jet printer that had not been invented
when the bonds were allegedly produced.
Zip codes were used even though they were not
introduced until 1963.

AICPA’s Position
AICPA’s Position (cont.)
• Does not require auditors to carryout specific
forensic procedures, but rather provide guidance
on how to include forensic techniques within
processes outlines in SAS 99. This combination will
enhance the detection and prevention of fraudulent
financial statement reporting and misappropriation
of assets; thus protect investors and financial
statement users.
• Public accounting firms could use forensic
accountants to help revise their approach to
planning and fieldwork on all audits, while
requiring forensic accountants only on high risk
audit clients to aid in the interpretation of forensic
testing results and preventive control enhancements.
• The inclusion of audit procedures focused towards
detecting misappropriation of corporate assets may
lead to the identification of weaknesses within
corporate governance or control weaknesses. Frauds
that are identified which represent a material
misappropriation of assets could significantly
15
impact public perception.
• Professional forensic accountants can best be used
by ensuring such procedures are properly developed
and executed in-line with internal audit and audit
committee concerns. Forensic accountants could then
be engaged in high-risk situations, or when a fraud
is suspected.
• Companies should not use the forensic services of
their outside audit firm, unless it pertains to the
annual audit.
• Putting a price on a substantive test or forensic
auditing procedure may be smart for business;
however, the inherent risk is that short-cuts geared
towards reducing audit costs may eventually cause
investors to question the companies’ true financial
position.

• Supervisor of the Real Property Tax
Adjustment Unit in Washington, D.C., Harriette
Walters, used at least 92 payments to dummy
corporations in a scam to obtain $31.7 million
($344,565 per refund).
Michelle Cawthra testified that she deposited
unclaimed tax refunds and other money into
Hysear Randell’s bank account over two years.
She forged documents and created fake
businesses. Michelle used computer passwords
of other workers so she would not be detected.

• Fraud was never noticed by city officials,
internal, or external auditors. Auditors never
examined why the city’s property tax refunds
were steadily rising.
• Sham companies’ bank accounts were
controlled by Walters’ brother.
• Many applications for refund were identical to
prior ones.
• In a FBI raid of her house, 100 pieces of
jewelry, a mink coat, 90 designer purses, 68
pairs of shoes, designer luggage, Rolex watch,
silver bar cart, and more were found. She had a
$1.4 million in bills at Neiman Marcus on a

Where Is $9 Trillion? The U.S. Federal Reserve can not
account for $9 trillion in off-balance sheet transactions.
Also, no one at the Federal Reserve has any idea what are
the losses on its $2 trillion portfolio.
On May 12, 2009, Inspector General Elizabeth Coleman
could not explain the $1 trillion plus expansion of the
Federal Reserve’s balance sheet since September 2008.
While testifying before Congress, Coleman said the IG
does not have jurisdiction to audit the Federal
Reserve.86
If a U.S. business lost $9 trillion or created $9 trillion on
their balance sheet, they would suffer severe penalties.

Finding Unreported
Income/Hidden Assets
Forensic Accountants
“Rather than combing torn clothing,”
forensic accountants “comb through
corporate books, looking for oddities
that could signal swindles,” says Bruce
Dubinsky. Investigations can be
extremely complex, with crates and
crates of documents and thousands of
computer files. Investigators look for
flags or patterns that would not
normally occur.

4.
Look at the lifestyles.
Look at the expenses.
Look at the cash flow.
Look at the business
operations.
5. Look at the industry ratios.
6. Consider using private
investigators.
7. Use the net worth method.

Find It, or I’ll Sue
Forensic Accounting Knowledge Base
Accountants must be attuned to
detecting fraud at every level of
service, including standard
accounting services, compilations,
reviews, and bank reconciliations. If
there is fraud and you don’t detect it,
you are going to be sued, and you
will likely lose, as the public
perception is the accountant is the
watchdog.

General Counsel Roundtable
says that each $1 of compliance
spending saves organizations, on the
average, $5.21 in heightened
avoidance of legal liabilities, harm to
the organization’s reputation, and lost
productivity.

Auditors will continue to miss fraud because
much of their work is predicted on the
assumption that separation of duties
prevents fraud (i.e., one person hold the
money and another person keeps track of it).
The Equity Funding case shakes the
foundations of auditing in that so much is based
on the assumption that people don’t collude
very long. These people work together as an
efficient team for a very long time [9 years].

Financial Audit v. Forensic Audit
The typical financial audit is a sampling
activity that doesn’t look at every transaction
and can therefore be exploited by someone who
knows how to rig the books.
Forensic accounting focuses on a
specific aspect of the books and examines
every digit. While the average accountant is
trying to make everything add up, a forensic
accountant is performing a detailed financial
analysis to find out why everything doesn’t or
shouldn’t add up.
It’s a far more time-consuming enterprise
and can be significantly more expensive than
regular auditing work.
Jake Poinier, “ Fraud Finder,” Future Magazine, Fall 2004,
http://www.phoenix.edu/students/future/oldissues/Winter2004/fraud.htm
Two Major Types of Fraud
Investigations
• Reactive: Some reason to suspect
fraud, or occurs after a significant
loss.
• Proactive: First, preventive
approach as a result of normal
operations (e.g., review of internal
controls or identify areas of fraud
exposure). There is no reason to
suspect fraud. Second, to detect
indicia of fraud.

Proactive Is Best
Proactive vs. Reactive Approaches
Proactive approaches include
Effective internal controls,
Financial and operational audits,
Intelligence gathering,
Logging of exceptions, and
Reviewing variances.
Reactive detection techniques
include
Investigating complaints and
allegations,
Intuition, and
Suspicion.

When the IRS began requiring banks
to issue Form 1099s reporting interest,
the reported interest income increased
by $8 billion (even though for 3 years
the IRS did not have computer
matching capacity).
When the IRS began to require
taxpayers to list a social security
number for dependents, the next year
the number of reported dependents
dropped by seven million. More than
11,000 of these taxpayers claimed
seven or more dependents in 1986, but
they claimed none in 1987.
When the IRS began to require
taxpayers to list a name, address, and
social security number for babysitters,
two years later 2.6 million babysitters
disappeared.

Fraud Deterrence Better Than Fraud
Investigation
1. Fraud deterrence less expensive.
2. Deterrence is more
comprehensive.
3. Fraud deterrence produces
greater savings.
4. Deterrence is faster.
5. Fraud deterrence promotes better
customer relations.

Walkthroughs
© D.L.
Crumbley
An auditor must perform a walkthrough
of a company’s significant processes (each
major class of transactions).
Can not be achieved secondhand.
According to PCAOB, in a walkthrough
an auditor traces “company transactions and
events – both those that are routine and
recurring and those that are unusual – from
origination, through the company’s accounting
and information systems and financial report
preparation processes, to their being reported in
the company’s financial statements.”
Auditors should perform their own
walkthroughs which provides auditors with
appropriate evidence to make an intelligent
assessment of internal controls.

Measures Helpful in Preventing Fraud
•Informal observations while in the business.
•Especially valuable when assessing the
internal controls.

Financial Audit v. Forensic Audit
Contrasting Auditing, Fraud Examination, &
Forensic Accounting
The typical financial audit is a sampling
activity that doesn’t look at every transaction
and can therefore be exploited by someone who
knows how to rig the books.
Forensic accounting focuses on a
specific aspect of the books and examines
every digit. While the average accountant is
trying to make everything add up, a forensic
accountant is performing a detailed financial
analysis to find out why everything doesn’t or
shouldn’t add up.
It’s a far more time-consuming
enterprise and can be significantly more
expensive than regular auditing work.

Forensic Audit,” Journal of Digital Forensics,
Security, and Law, 2009, Vol. 4, No. 1, p. 69.
Auditing is a macro process, and forensic
accounting is a micro process.

Social Engineering Schemes
• Find out who did it. Do not worry about all
the endless details.
• Dumpster diving – Sifting through
companies’ dumpsters (Proctor & Gamble
went through Unilever’s dumpster. 80
valuable documents).
– Lock Dumpsters.
– Use across-cut shredder.
– Check dumpster outside client's
building (e.g., restaurant).
• Shoulder surfing (e.g., looking for
passwords; then plant stuff on your
computer).
• Tailgating: following someone into a
business behind someone with authorized
access, then lost your identity badge.
• Be creative, think like the fraudster, and do
not be predictable. Lower the auditing
threshold without notice.
• Take into consideration that fraud often
involves conspiracy.
• Internal control lapses often occur during
vacations, sick outages, days off, and rest
breaks, especially when temporary
personnel replace normal employees.

Chain of Custody
Round Numbers Red Flag
• Just as in the movies or on a television
show such as CSI, forensic
accountants must safeguard evidence
through a financial chain of evidence.
• There must be a way to show that the
evidence has not been tampered with
or damaged.
• If documents are seized, the forensic
accountant should put his or her
initials and date of the seizure on the
back of each document.
• Or put the document in a transparent
envelope and write a description on
the envelope.
• Store the original and work only with
a copy.
Areas where rounded number should
not be expected:
Amounts on tax returns(T&E).
Inventory counts.
Regulatory filings.
Accounts receivable balances.
Journal entries.

Continuous Monitoring
• Management engages an independent outside supplier to
install and manage software to continuously analyze every
transaction within business applications to detect improper
activities and anomalies that indicate errors, control
overrides, and fraud [Oversight Systems].
• The software sorts incidents into errors, misuse, and fraud
(a detective control).
• Suspicious transactions can be identified and categorized
for future follow-up.
• Flag items such as manual income-increasing adjustments,
adjustments made late in the year, large dollar amounts.
• Large companies with revenues over $1 billion.
• Over the course of a year monitoring each module (e.g.,
A/P, Sales, G/L) is designed to cost approximately the
amount the company would pay for one fulltime internal
auditor per module.
• One company saved $2 million of external auditing fees
for using C/M in the 404 area.

Timeline Analysis
• Timeline analysis (TA) may be used
to show the timing of a dispute, and
certain software tools can prepare trial
exhibits.
• Investigative analysis software can
show all detail from the beginning of
the event until the apprehension of the
target.
• TA helps forensic accountants
communicate the timing of case
related events and summarizes the
investigation.
• Each link of the timeline chart
includes a reference to a source or a
direct link to a database. An insurance

Invigilation Technique
• Invigilation is a rather expensive

used in potential fraud situations to
discover the fraud and can later be
used in the courtroom.
• Here detailed records are kept before

determine the amount of fraud.
• During the invigilation period strict
controls are imposed (e.g., cameras) so
that the fraud is virtually impossible.
• Or the invigilation period could be
while the suspect is on vacation.

• There are software programs that are
custom designed for genograms, such
as GenoPro 2007 ($49 at
www.genopro.com).
• Simple symbols represent the gender
(box for male and circle for female),
with various lines to illustrate family
relationships.
• People who are not related would not
be connected with a line, but could be
placed on the genogram.
• They can lead to determining the
motive of a crime or provide evidence
that the person had no direct
involvement in the fraud.

Proof of Cash
Tracking Small Sums
•
FAs can employ aberrant pattern detection using digital analysis.
Benford’s Law is the DNA equivalent of numeric testing using
geometric progressions against actual transactions. Another
technique, full and false inclusion, is known as the yellow
crime scene tape of forensic accounting. It insures that no
extraneous data is included and no appropriate data is excluded.
Another very interesting technique uses Genograms, which are
visual representations of personal relationships. It is a tool that is
been borrowed from family counseling.
•
First, FAs track people. Then the money is easy to find. The
money takes different forms, of course: cash, accounts, hard
assets such as real estate and automobiles, intangible assets like
patents, copyrights, trademarks, promissory notes, betting
records. Both money and people leave trails: phone records,
voting records, even genealogy research. In fact, the trails left in
a free society are very useful in catching terrorists who attempt
to use our freedom to their advantage.

seemingly unrelated parties and entities.
• Microsoft Excel drawing tools may be
used to prepare entity charts.
• For example, an entity chart could show
the creation date of off-shore bank
accounts and the subsequent decrease
in the target’s U.S. bank accounts.

AICPA Practice Aid 06-2 suggests a financial
model could be used in these situations:
• Reviewing or developing planning concepts in the
client organization.
• Full-and-false inclusion tests may be
helpful for finding hidden assets.
• Selecting, gathering, compiling, validating, and
assessing data required in the planning process.
• Yellow crime scene tape of FA,

Social Media in Divorce
According to the suit, Heebe enlisted a former FBI profiler
to review 595 comments left by "Henry L. Mencken"
below stories posted on NOLA.com.
The comments were compared to legal filings made by
federal prosecutors in their sweeping probe of the River
Birch landfill, which is co-owned by Heebe and his fatherin-law. The profiler found striking similarities in the
language, the suit says.
The petition notes that "Mencken" uses obscure words,
such as "dubiety" and "redoubt," that also appear in federal
filings in the River Birch case.
The suit says the analysis was conducted by forensic
linguist James Fitzgerald whose work for the FBI "proved
instrumental" in the arrest and successful prosecution of
Ted Kaczynski as the Unabomber, following a lengthy
investigation that included analysis of the mail bomber's
writings.

E-ZPass Catching Cheaters
Carbon Dating Paper and
Signatures
• E-ZPass and similar electronic toll collection systems
are emerging as a new and powerful means to prove
infidelity.
• Generally mounted inside a vehicle's windshield
behind the rearview mirror, the remote-sized, EZPass devices communicate with antennas at toll
plazas, automatically deducting money from the tagholder's prepaid account and recording when and
where the vehicle crossed the toll.
• Many states provide electronic toll information in
response to court orders for criminal and civil cases,
including divorces, which are used to prove the
defendant was not where he or she claimed to have
been.
• "E-ZPass is an E-ZPass to go directly to divorce
court, because it's an easy way to show you took the
off-ramp to adultery," said Jacalyn Barnett, a New
York divorce lawyer who has used E-ZPass records a
few times.
• There are reports of using radioactive carbon dating
and microscopy to prove the age of a document and
the age of the signature differ by a matter of years.
Dating the other writing on the paper further
corroborates the allegation of forgery.
• Sources have reported that in Atlanta, the procedure
has been used on the “original” note produced in
court by the pretender lender, proving the
document was a forgery even though the borrower
conceded the signature was authentic.
• If a document is dated 5 years ago, and the signature,
endorsement or assignment execution that is dated
on the paper is more recent, or the actual signature is
more recent than the rest of the document (the paper,
the other writing etc.) then the signature was not on
the document at or near the time of the document’s
creation.

Carbon Dating Paper and

• If it’s the borrower’s signature that has been
technologically reproduced and introduced as an
original, it means that the actual original note is
somewhere else. It also raises the possibility that
more “originals” are circulating in those
fictitious “Trusts” or “pools” purporting to claim
the obligation, note or mortgage.
• If the signature or the paper that is presented as
an assignment dated at or near the time of
closing with the borrower, but either the paper,
the signature, the witness signature or the notary
signature or stamp does not coincide with the
date of the purported document, the same
analysis holds: it is a forgery.

Forensic Information System for
Handwriting (FISH) U.S.
Department of Justice
The document-part image is acquired by scanning the entire document and
selecting the desired part by using a 6.5 x 6.5 cm ruled square. Once the block
of writing is selected, the document is rescanned, producing an enlargement
of the part on the screen. By adjusting the contrast between the writing and
the paper surface to conform to that of the original document, the examiner
can present features, such as tapered beginning and ending strokes or light
connecting strokes, as they appear on the original document. The examiner
may also remove unwanted features from the document image. The feature

The Hitler Diaries Debacle
(1980s)
It was an analysis of the ink and paper used to
write the diaries that revealed them as fakes. An
ultraviolent-light examination revealed that the
paper contained an ingredient that wasn't used in
paper until 1954. Hitler died in 1945. Further
forensic tests on the ink showed it had been
applied to the paper within the last 12 months.
As it turns out, though, the handwriting analysis
was in fact correct – the person who’d written the
diaries had also written the exemplars. Konrad
Kujau, later found out to be an experienced con
artist, had also forged the exemplars the police
were using as comparison documents.
The first step is the text-insensitive feature extraction (TIM), an automatic
process in which FISH marks the exact center of the part and draws eight
vectors out to the edges. The system then uses black-and-white pixel chain
formations and auto-correlation functions to mathematically treat and store
the writing, the TIM is then saved and isolation for selected features begins.
This involves circling the desired letter or combination.
The next extraction deals with tracing or line-following. A set of
measurements then marks the height of the base ovals. At least 10
measurements are taken. After the interactively measured features are
recorded a screen appears that lists the number of measurements taken, the
median measurement, and the standard deviation for each category.

Some Contract/ Procurement Frauds
• Breach of contract: a party fails to perform or
says he/ she will not perform. Other party can
sue for damages.
• The intentional failure to perform a contract,
however, does not necessarily constitute fraud.
• Must show that the party did not intend to
perform the contract and deliberately misled
the other party.
• Civil or criminal action: party knowingly and
willfully that the contract (or statement) was
false with the intent to deceive or defraud.
• With this extra burden, may not be worthwhile
to try to prove the fraud. Just get rid of the
person because of a conflict of interest.

Deficits in major funds in excess of 1.5% of fund expenditures or

Some analysts use a variation of this ratio: the budgetary
cushion. Here the fund balance is compared to revenues. The
greater the fund balance as a percentage of revenues, the more
likely a local government may weather hard times. A good rule
of thumb is that a fund balance should be at least 5% of
revenues.[1]

A government should generally have year-end cash equal to about
50% of current liabilities and 75% of average monthly expenditures.
A governmental accounting textbook states that this quick ratio (or
acid test) omits receivables and amounts due from other funds
because of difficulties converting them into cash. They suggest that a
large state government should consider a quick ratio of less than 50
percent as an indicator of financial stress.*

Acquisition/Payment Cycle
From 62 standard audit procedures, external and
internal auditors judged these 20 procedures to be more
efficient is detecting fraud in the acquisition and
payment cycle (in descending order).
• Examine bank reconciliation and observe whether they
are prepared monthly by an employee who is
independent of recording cash disbursement or custody
of cash.
• Examine the supporting documentation such as
vendor’s invoices, purchase orders, and receiving reports
before signing of checks by an authorized persons.
• Examine the purchase requisitions, purchase orders,
receiving reports, and vendors’ invoices which are
attached to the vouchers for existence, propriety,
reasonableness and authenticity.

• Confirm inventories in public warehouse and on
consignment.
•Examine internal controls to insure the vendor’s
invoices, purchase orders, and receiving reports are

vendor’s invoices, receiving reports, purchase orders,
and receiving reports.
• Trace a sample of acquisitions transactions by
comparing the recorded transactions in the purchase
journal with the vendor’s invoices, purchase requisitions,
purchase orders, and receiving reports.
• Establish whether any unrecorded vendors’ invoices or

duties between accounts payable and custody of signed
checks for adequacy.
• Reconciled recorded cash disbursement with
disbursements on bank statements.

You receive a tip on the company’s hot line that
there has been some fraud in the collections area.
What five audit steps would you suggest using in
order to find the fraud?
During a brainstorming session, a suggestion is
made that the most likelihood of fraud in a
particular division is in the area of acquisition and
payment cycle. Outline five audit steps to help
find any potential fraud.
While auditing a company you notice an
employee in payroll who is living beyond his
means (e.g., clothes, automobiles, housing). His
wife does not work. Suggest six audit steps to
help satisfy you there is no fraud in the payroll
and personnel cycle.
An anonymous e-mail is sent to an internal
auditor that there is fraud in the inventory/
warehousing cycle. Suggest some appropriate
audit steps.
