Key Financial processes being electronized
measurement (accounting),controlAssurance
evolving revolution in corporate financial processes and the financial industryseveral world class organizations are leading this effort
Continuous reporting
SEC roundtable of 4/4/2002
Priority no. 1: real-time reporting. Real-time reporting should take highestpriority. More frequent reporting of results will help solve the problem ofmanaged earnings because daily or weekly earnings will be harder to managethan quarterly earnings. SEC's proposal for faster reporting of some 8-Kitems is helpful, but it doesn't go far enough.
Short interval reporting
Cisco’s virtual closeReal balances of certain accounts
Cash, accounts receivable, accounts payable, inventoryEstimates / allocations
Behavioral changesEnd-of-period adjustmentsCompetitive fears
Scorecards (Bob Kaplan)
Increased frequency and scope of reporting
Obstacles are not technicalInternal vs external reportingLitigation fearsWho needs continuous reporting?Increased transparencyQualitative, environmental, social, and other reportingMulti-layered reporting (the FD rule)
Is Continuous Reporting Necessary for Continuous Assurance?
‘continuous’ measurement is necessary, but the time from is contingent on the processBatch process cycles limit the processCompanies measure a much wider set of variables to support a multitude of continuous processes
The Assurance Services (Eliott) Special Committee proposed an evolution of services towards “real-time” assurance

History
CPAS effort and embedded modules (ITF) –1987AICPA /CICA monograph 1999Continuous systrust 2001Panel next ?????Much academic interest since 1999 (3 symposia, this year in the UK)
Current Practice
HCA HealthcareSeveral monitoring and auditing functions
Martin MariettaData driven risk model
Federal Reserve of New YorkNetwork Monitoring
Why not?
“my problems are not with transactions but with legal exposures and environmental effects”“this is not auditing, it is supervision”“this opens substantial data for the competition”
A Dramatic Change in the Audit model
1. The continuous assurance model has many clients2. The continuous assurance model has a different justification3. A new toolset4. The continuous assurance model is an instance of operational monitoring5. The continuous assurance model will turn the audit process into audit by exception6. The continuous assurance model covers a wider set of quantitative and qualitative non-financial data7. The continuous assurance model had different Independence considerations8. The continuous assurance opinion has some futurity implied in it
Pseudo report 1– We have examined the reliability and financial reports of
ABC corporation and have been engaged on a continuous assurance engagement for the fiscal year of xxxx. We will monitor the organization’s operations and strategic accomplishments using a wide set of analytics as described in http://www.ca.com/analytics and other analytics we deem appropriate and will report on an audit by exception basis when more than xx % variance is found in operational and strategic standards or when we deem it appropriate. This exception report will be issued to all customers registered ( paying ) at http://www.ca.com/analytics/customers.

alarmsmeasurement vs monitoring
CPAS conceptsThe essence of monitoring and control is the comparison of a measured value (metric) with a model of behavior (standard)Control of a process implies detecting variances and either accepting them or exerting action for changeAssurance is a meta-level for measurement, monitoring and control that detects anomalies in this process or provides re-enforcement of its proper performance
Monitoring, control and assurance

Comparison of actual and model
Management action on discrepancy

MeasurableProcesses
Standard
Discrepancy detected
metricsAre direct measurement of elements that measure corporate processesCan be expressed in many types of units
A phone call has minutes, origination, dollars and modified dollars..Metrics also work in aggregates (e.g. bottles, cases, liters, tons, etc…)
Automated sensor substantially improve the value of a metricsMetrics can be combined to higher level meaning metricsManagers develop intuitive feeling for metrics
Analytics
Traditional analytics encompass time series and cross-sectional analyticsCA adds structural analytics provided by multivariate continuity equationsSome CA analytics include:
Comparisons with constantsRelationships of variablesDaily, hourly, continuous reconciliationsLoose relationships (e.g 10% increase in advertising creates 3% increase in sales)
standards:
Types• of operation• of variance• relationships • Others
Can be• empirically derived• model derived
Have to be realist

Methods of data capture
measurement vs monitoringDatabase queriesCapture of temporary datasetsParsing of electronic reportsDirect process taps programmed into the transaction routes
Principles of Continuity EquationsDifferent stages of the product life life have different metricsContinuity of processes creates relationships between different variablesMost processes have metrics being expressed in different units (volumes, dollars, units, etc…)There are intrinsic relationships between these values that can add substantively to basic analytical reviewStandards must be developed to these relationshipsThe understanding of these relationships will avoid major process discontinuities or will identify them for scrutiny

Linking financial and non financial processes analytically
CPAS effort (II)The auditor will place an increased level of reliance on the evaluation of flow data (while accounting operations are being performed) instead of evidence from related activities (e.g. preparedness audits). Audit work would be focused on audit by exception with the system gathering knowledge exceptions on a continuous basis.

New technologies need new thinking
Internetworking and extreme intrusionConfirmatory extranetsAnalytic webs and fourth and fifth party assuranceIntelligent transaction detection
Sniffers, exposure databases, pattern detectors, common fraud databases
The Enron debacle
Would CA have detected the problem?Would have reduced itIf transparency is desired it can be obtained to the extreme• Other forms of third party monitoring can deal
with management fraud and audit collusion• Are we willing to go that far?
Financial engineering and opacity together are a deadly mix

Conclusions
Need to re-think third party assurance wit focus on the clientNeed to rethink the audit to use new technology (analytic, IT and TC)More links are needed with XML derivative technologiesWe need a new business model
