Learning Objectives
“The Trailers for 2015”
Use a case study set of examples in payables, general ledger, and travel and
entertainment spend to see how audit steps can be automated into Excel.
Use Excel as audit software, able to mimic practically all data analytic
commands found normally in more expensive tools.
Get started with and quickly maximize Pivot Tables, turning them into effective
data mining tools able to unearth almost any audit finding.
Visualize and otherwise chart changes over time and/or other chart dimensions.
Discover a key word analytic and the value of completing word and letter
summaries.
Learn to select a sample in Excel and consider scoring for improved hit rates
and reduction of false positives.
Discover how analytics can maximize the annual audit plan and better ensure
focus is placed on organizational risk.
Using analytics across the entire lifecycle from risk assessment, to planning,
fieldwork, and reporting

7. It’s The Trends
Looking at 100%….Right?
Trend categories of spend and revenue
Trend by person and title entering and approving
Trend the trial balance for a variety of periods
Trend vendors / customers (it is possible via the G/L)
Trend before and after quarter end
But You Need the Auditor To “Blink” At The Data
Page 12
Or the Deviations?
Unexpected Trends or Spikes
Specific Queries
 Align sub ledger to the trial balance or general ledger
• Even for reasonableness!....and to review activity trends
 Above average testing and auto-extraction
 Duplication testing (sales, vendors, etc.)
 Employee to vendor bank account match (disparate data match)
 Entries posted by employees not authorized to post transactions
Sampling Techniques
 Sampling (Random / Statistical / Stratified)
 Record / Transaction Scoring

But You Still
Need the
Auditor To
“Blink” At
The Data….

8. Polling Question #1

Low ratio of duplicate transactions to all vendor
transactions
Below average days payable or sales outstanding
Above average credit limit to all customers
Page 17

10. Above Average Analysis
Page 18
Focus on 2 and 3 Std Deviations
Consider Sampling “Strata of Z”
New Functions To Learn
Average – Provides the mean
Stdev – Provides the standard deviation
Standardize - Z Score
Norm.Dist - Percentile per value
Percentile – Value for a percentile
Count – Counts the observations
Page 19

11. Polling Question #2

 Group Date
 Pivot Chart
 Line Chart
Page 29

16. Red Flag (Key) Word Phrases
Lessons from WorldCom/ MCI
The fraud was accomplished primarily in
two ways:
1.Booking "line costs" (interconnection
expenses with other telecommunication
companies) as capital expenditures on
the balance sheet instead of expenses.
2.Inflating revenues with bogus
accounting entries from "corporate
unallocated revenue accounts".
In 2002, a small team of internal auditors
at WorldCom worked together, often at
night and secretly, to investigate and
reveal $3.8 billion worth of fraud….
Per Wikipedia – MCI Inc.

17. Red Flag Word Phrases/Words
• One could build a database of suspicious words
and then search the entire data file for these
words, looping back to the table to get the next
word:
• bribe
• fraud
• plug
• etc.
• Summaries can be done by person and
collectively for additional collusion reviews

Lanza’s Letter Fingerprint?
A Law For Letters and Words?

Benford’s Law of Letters?

19. Textual Analytics Summary
It works fast to quickly gain a perspective of the business process data:
 Can work in real-time with the data while talking to the client – no prep
needed…meaningful questions in seconds
 Look for deviations over a 3 year moving average to the current period
If Digital Analysis / Benford’s Law is latitude, textual analytics is
longitude
 Text is far richer in business value and providing a picture than simple digit
theory
 The unique word chart provides a more normalized view of activity while total
word occurrences by letter provides a more dynamic chart
 The trends can be seen quickly to ask relevant questions and also to
highlight fraud
Why not use another approach, like Benford’s Law, to look at ALL data
quickly by trending on a natural law of letter usage for that business
approach
Polling Question #4
What was one of the phrases used in the
MCI case?
 Line management
 Cost recovery
 Key controls
 Line costs
Page 37

20. Specific Queries and Sampling
Top Sided Journal Entries
Risk Factor Reports
 Entries to revenue with offsets NOT in accounts receivable or cash
 Extract nonstandard or manual journal entries (versus a created system such as
an accounts payable ledger posting) for further analysis.
 Extract journal entries posted on weekends and holidays.
 Extract journal entries relating to the prior year that were made just immediately
following a fiscal-year end.
 Extract general ledger transaction amounts (debit or credit) that exceed the
average amounts for that general ledger account by a specified percentage. (Five
times the average is the default.)
 Extract journal entries that equate to round multiples of 10,000, 100,000, and
1,000,000.
 Extract journal entries with key texts such as “plug” and “net to zero” anywhere in
the record.
 Extract journal entries that don’t net to zero (debits less credits).
 Extract journal entries made to suspense accounts and summarize by the person
entering and corresponding account numbers.

21. Specific Accounts Payable &
Travel & Entertainment Tests

10,000, 100,000, and 1,000,000.
(When) Extract transactions posted on weekends and
holidays.
(When) Identify longest time to enter an invoice
(Who) Extract T&E transactions when a person was on a

Page 42
Auditors Inherent Need
To Sample
Page 43
The practice of selecting individual
items from a population to estimate
properties of that population….
given confidence levels around top
error patterns and expected errors.
This is statistical sampling vs.
judgmental (nonstatistical)

Stratify Your Data – Ver 1
Page 45
=IF(B4>1000,“3. Over $1000",IF(B4>100,“2. Over
$100 to $1,000",IF(B4<=100,“1. Up to $100")))
This will create three strata:
1. Up to $100
2. Over $100 to $1,000
3. Over $1,000
Start from highest to lowest – Excel picks the first
matching item

24. Stratify Your Data – Ver 2
Page 46
Polling Question #5
In order for the stratification of value to
work, what is the last setting of the
Vlookup?
 FALSE
 MAYBE
 TRUE
 YES
Page 47

25. Benefits of Stratified Sampling
Focuses attribute testing at larger values
 In dollars
 In risk
Allows for more varied subsamples
Allows for error rate calculations by type
 Department
 Location
Page 48
Stratification Types
By Month
By Department
By Business Partner (Vendor / Customer)
By Account
By Enterer
Page 49

26. Narrowing the Focus With Transaction Scoring
Approach - Transactional
Score Benefits
The best sample items (to meet your attributes)
are selected based on the severity given to each
attribute. In other words, errors, as you define
them, can be mathematically calculated….so
best to tailor them
Instead of selecting samples from reports,
transactions that meet multiple report attributes are
selected (kill more birds with one stone).
Therefore a 50 unit sample can efficiently audit:
 38 unbalanced entries
 22 round entries
 18 unique entries
….and they are the best given they are
mathematically the most “severe”.
