Preface
This Audit Manual was first produced for the Office of The Auditor-General for Local
Governments in Lagos State in November 2005. It was subsequently fully revised in
December, 2012. The intention of the manual is three-fold. Firstly to ensure that audits are
performed in line with audit standards and best practices; secondly to ensure compliance with
the Model Financial Memoranda for Local Government and other statutory regulations as maybe revised from time to time; and thirdly to reflect the good practices which have been
developed in my office.
This Audit Manual is designed to enhance and standardise audit practice within the Office of
the Auditor-General for Local Governments by promoting the sharing of knowledge and good
practice. This should encourage standard uniform practice expected to facilitate peer review
and self-evaluation by the Audit team. This in turn will lead to improved performance which
would assure quality service delivery to Local Governments in Lagos State.

Foreword
The mandate of the Auditor-General for Local Governments, in broad terms, is to examinehow well theLocal Governments have managed their financial affairs and to report the results
of these examinations to the State House of Assembly through the Public Accounts
Committee (Local).
The Audit Manual sets out the principles and audit procedures which are to be followed by
every audit team member when auditing or undertaking audit related assignments in Local
Governments, Local Government Education Authorities and allied agencies or when called
upon to carry out investigations into matters that may have come before the State Assembly
or indeed the Office of the Auditor-General forLocal Governments (OAGLGs).
The manual sets out the high standards of professional serviceswhich theAGLG- expects of
his staff and reflects current International Standards on Auditing and I trust that the manual will
add value to the work undertaken by all audit teams. It is a reform strategy brought about by
the need to enhance service delivery and productivity of this office. As a symbol of "Public
Trust and Accountability", this manual will aid compliance with International Standards and
align us with the aspirationof Lagos State Government in achieving timeliness, adequacy and
effectiveness in financial reporting.
The Manual is expected to be a reference point for the continuous improvement of our audit
practice.As our knowledge of and experience with auditing continues to expand and evolve,
so will this Manual. The Manual has been prepared for use in guiding our audit programmeand tasks. We recognise that some changes to this document may be necessary in order to
ensure that the Manual is kept upto date and current. Therefore, this manual, in its entirety,
will be subject to review from time to time to in order to:
Keep up with new developments in audit practice,
Effect legislative changes as they affect the objectives of the Office of the Auditor
General for Local Governments from time to time and
Keep up with the challenges of our assignments.
Audit Teams should be proud of this Revised Audit manual and as such are expected to be in
full compliance with its contents on an ongoing basis. All new staff members are required to
read for retention, the contents of this Manual.
Comments or suggestions for improving the Manual are welcome and such should be
addressed to the Auditor-General for Local Governments, Lagos State.
I wish to express my profound gratitude to the Growth and Employment in States (GEMS3)
project, funded by the Department for International Development (DFID) of United Kingdomwho engaged Andy Wynne and F.O. Lasisi to work with my staff to review and revise the
Manual in line with INTOSAI international auditing standards and current good practices in my

CHAPTER 1
INTRODUCTION
1.1 Introduction
This manual is a revision and modernization of the first ever Local Government Audit Manualwhich was developed in 2005. The revision of the 1965 Audit Manual was necessitated by theneed to reflect changes in good practice in the execution of Local Government audits
This manual is prepared for the use of the staff of the Office of the Auditor General for LocalGovernments to explain the processes and procedures necessary to carry out auditing in anorderly and efficient manner. The purpose of the Manual is to offer practical guidance to LocalGovernment auditors. The manual is designed to meet the requirements of all Auditors in theOffice of the Auditor General for Local Governments.
Every audit needs to comply in various respects with the requirements of legislations,professional standards and best practice. This Manual sets out policies and practices thatshould be applied to meet these requirements. Although approach should always be tailoredto meet the individual circumstances of each audit, the framework will normally be the sameon every audit.
The manual will need to be continually updated to reflect changes is approach andrefinements to the audit methodologies adopted or to reflect changes in the regulatoryenvironment, for example, the format of the annual financial statements. In addition,additional sections may need to be added, for example, covering the work undertaken directly
for the Public Accounts Committee (Local) Public Accounts Committee (Local) of theState House of Assembly and formal risk management.
1.2 Knowledge of the ManualAll audit staff in the Office of the Auditor General for Local Governments are expected to havea reasonable knowledge of this manual and to follow the good practice it contains during theirwork. Audit staff have the responsibility to report areas where the manual needs to beupdated or is considered to be deficient.
1.3 Overview of the ManualThe main work of the Office of the Auditor General for Local Governments is to undertake
quarterly inspection audit visits to all of the 57 local governments and local councildevelopment areas (referred to generically in this manual as local governments) in LagosState. Chapters 2 to 6 cover this work from planning to reporting. This work is mainlyregulatory or compliance audit.
Part two of the manual covers other aspects of the work of the Office of the Auditor Generalfor Local Governments that are also important. These include, for example, financial audit(opinion on the financial statements), inspections of completed capital projects, staff andpensioner verification.
1.4 Overview of Quarterly Audit Inspections
This work follows five main stages which are each covered in a chapter of the manual:
Planning

Lagos State Local Government Audit Manual Version 2.2 December 2012
Evaluating internal controls
Audit testing
Documentation of audit work
Audit reporting.
This process is also shown in the following diagram:
Key
A - Procedures are mostly analytical procedures
B - Procedures involve usage of basic substantive procedures
C - Procedures entail execution of comprehensive testing
D - Procedures entail detailed testing of audit evidence.
Planning is important to ensure all aspects of the work are completed and the work is
-
7/30/2019 Lagos Audit Manual - Part One
10/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
undertaken efficiently. It occurs at two levels:
planning the time and number of auditors to visit each local government
planning the allocation of audit tasks to each auditor with time budgets.
Evaluation of internal controls is an important first step for each inspection visit. Auditorsshould be able to gain some assurance from the quality of internal financial controls and mayassist the local government by making detailed recommendations on how these may befurther improved. If the internal controls are considered to be strong then only a sample ofpayment vouchers and other transactions may need to be checked.
Audit testing is a core part of this audit work. Tests need to be undertaken carefully toensure that all significant irregularities are identified and to assist with determining theappropriate audit opinion on the annual financial statements.
Documentation of audit work is necessary to ensure that the work can be properly
supervised and to ensure that adequate evidence is available to explain the results of ourwork to the Chair and Council Treasurer of the local government. It is also needed to ensurethat the Auditor General can report adequately to the Public Accounts Committee (Local) oneach local government.
Audit reporting is the output and the public face of our work. Improving public accountabilityis a core part of the work of the Office of the Auditor General for Local Governments and ourreports are available to be the public and so must be written carefully to ensure that all keystakeholders understand the work which has been undertaken and the results that we havefound. The most important stakeholder is the Public Accounts Committee (Local) of the LagosState House of Assembly.

Annex A
The INTOSAI basic principles are:
(a) The SAI should consider compliance with the INTOSAI auditing standards in all mattersthat are deemed material. Certain standards may not be applicable to some of the work doneby SAIs, including those organised as Courts of Account, nor to the non-audit work conductedby the SAI. The SAI should determine the applicable standards for such work to ensure that itis of consistently high quality.
(b) The SAI should apply its own judgement to the diverse situations that arise in the course ofgovernment auditing.
(c) With increased public consciousness, the demand for public accountability of persons orentities managing public resources has become increasingly evident so that there is a needfor the accountability process to be in place and operating effectively.
(d) Development of adequate information, control, evaluation and reporting systems within thegovernment will facilitate the accountability process. Management is responsible forcorrectness and sufficiency of the form and content of the financial reports and otherinformation.
(e) Appropriate authorities should ensure the promulgation of acceptable accountingstandards for financial reporting and disclosure relevant to the needs of the government, andaudited entities should develop specific and measurable objectives and performance targets.
(f) Consistent application of acceptable accounting standards should result in the fairpresentation of the financial position and the results of operations.
(g) The existence of an adequate system of internal control minimises the risk of errors andirregularities.
(h) Legislative enactments would facilitate the co-operation of audited entities in maintainingand providing access to all relevant data necessary for a comprehensive assessment of theactivities under audit.
(i) All audit activities should be within the SAI's audit mandate.
(j) SAIs should work towards improving techniques for auditing the validity of performancemeasures.

Chapter 2
Audit Planning
INTOSAI Auditing Standards state:
The auditor should plan the audit in a manner which ensures that an audit of high quality is carried
out in an economic, efficient and effective way and in a timely manner.
The following paragraphs explain planning as an auditing standard.
3.1.2 The SAI should give priority to any audit tasks which must be undertaken by law and assess
priorities for discretionary areas within the SAI's mandate.
3.1.3 In planning an audit, the auditor should:
(a) identify important aspects of the environment in which the audited entity operates;
(b) develop an understanding of the accountability relationships;
(c) consider the form, content and users of audit opinions, conclusions or reports;
(d) specify the audit objectives and the tests necessary to meet them;
(e) identify key management systems and controls and carry out a preliminary assessment to identifyboth their strengths and weaknesses;
(f) determine the materiality of matters to be considered;
(g) review the internal audit of the audited entity and its work program;
(h) assess the extent of reliance that might be placed on other auditors, for example, internal audit;
(i) determine the most efficient and effective audit approach;
(j) provide for a review to determine whether appropriate action has been taken on previously
reported audit findings and recommendations; and
(k) provide for appropriate documentation of the audit plan and for the proposed fieldwork.

2.1 Key Requirements
The key requirements of this chapter are:
Each audit inspection visit should be carefully planned and the size of the team and
length of the visit adjusted to reflect the audit risk of the particular local government
The Permanent and Current Files should be carefully maintained to document all keyaspects of the audit inspection and act as a guide for future audit visits
AnAudit Planning Sheet(see Annex A to this Chapter) should be develop as a guidefor the audit, provide a common purpose for the team and to form the basis ofallocating jobs/activities to team members (with time budgets)
Audit activities should be allocated with the aim of enriching the knowledge of all teammembers
The local government should be informed in adequate time of the date of the audit andthe names of the audit team members
The Zonal Coordinator should review and sign off the Audit Planning Sheet, theCurrent and Permanent Files.
2.2 Purpose of Audit Planning
Audit planning and the preparation of audit plans is important because it:
(a) Establishes the way in which we will achieve our objectives.
(b) Assists us to direct and control the work.(c) Helps to ensure that we devote sufficient attention to critical aspects of work.(d) Helps us to ensure that we complete our work efficiently and on time.
The overall audit planning process is a cascade of elements, as follows:
Annual Audit Plan||
Quarterly Team Work Allocations||
Operational Team Planning
2.2 Annual planning
An annual work plan is produced each year for the Office of the Auditor General for LocalGovernments. This includes a monthly plan with the planned activities for each Directorateand, in addition, quarterly plans for each directorate.
The main audit activities include:
quarterly visits to each of the 57 local governments
annual statutory report on the 57 local governments
-
7/30/2019 Lagos Audit Manual - Part One
14/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
reviews of the audits of the 20 Local Government Education Authorities and alliedagencies and production of annual report
annual staff/salary verification exercise (August) and monthly follow-up
capital projects inspection exercise (March)
pension audit on a continuous basis.
The Office of the Auditor General Local Governments annual work plan is printed and this is
made available to the Governor, Public Accounts Committee of the State House of
Assembly, State Ministry of Local Government & Chieftaincy Affairs, the Chairs of
the local governments and other stake holders on local government matters.
2.3 Quarterly Team Work AllocationsThe Director of Evaluation and Reporting writes to each local government with the dates of
commencement of the next quarterly audit at least a month before the plannedcommencement.
The Director of Evaluation and Reporting agrees the modality of audit for the next quarter anddetermines the audit teams and the local governments that they will visit in the next quarter.
Quarterly plans are produced and posted for the audit of the 57 local governments, indicatingthe Zonal Coordinators, the Team Leaders and Auditors and the local governments that theywill audit during the quarter.
Planning different sized local government
Local governments vary considerably in size with the largest being nearly three times the sizeof the smallest. In addition, to the risk assessment audit staff should be allocated to thedifferent local governments on the basis of their size and the level of competence of the teammembers.
The larger local governments may be audited with a team of four auditors rather than thenormal team of three auditors (including the Team Leader). Where the risk is high and so thelevel of audit work more demanding the length of the audit may also be extended to threeweeks rather the usual two. This is decided by the Director of Evaluation and Reporting.
It is usual to provide each audit team with one rural (usually smaller) and one urban (usuallylarger) local government to audit. Thus the team can spend more time on the larger council
and less time on the smaller local government.
Risk Model
To determine the level of resources or staff needed to undertake each quarterly auditinspection visit, it is necessary to undertake a review of the risks associated with each localgovernment and so the time needed to complete the audit. The type of information required toundertake this evaluation includes:
The size of the IGR (from Cash Flow, Statement 1)
Total Expenditure (Statement 5 Revenue & Expenditure).
The quality of internal financial control extent to which rules and regulations arefollowed in practice, bank reconciliations done on time? Staff vacancies? Quality of theCouncil Treasurer? see Chapter 3 of this manual for further guidance
-
7/30/2019 Lagos Audit Manual - Part One
15/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
The quality of the Internal Auditor
The audit opinion of the Auditor General Local Government in the last statutory auditreport (did the financial statements show a true and fair view.
Whether the local government is urban or rural.
The four factors can then be combined to provide an overall assessment of risk:
Risk factor High score 3 Medium score 2 Low score 1
Size of IGR (in Nmillions) More than 200 15 - 200 (2) Less than 15(1)
Volume of expenditure (in
Nmillions)
More than 750 300 - 750 (2) Less than 300(1)
Quality of internal financial
control
Poor internal control
(3)
Medium internal
control (2)
Good quality internal
control (1)
Quality of the internalauditor
Poor quality internalauditor (3)
Medium qualityinternal auditor (2)
Good quality internalauditor (1)
Previous audit opinion Financial statements
do notshow true and
fair view (3)
Financial statements
show true and fair view
(1)
Urban or rural local
government *
Highly urbanised local
government (1.5)
Medium (1) Highly rural local
governments (0.5)
*This criteria only scores half the scores of the others.
The scores for each factor are then added together to provide an overall risk score. Forexample:
Size of IGR = N150millions - Score 2
Volume of total expenditure = N8000millions - Score 3
Quality of internal financial control = poor - Score 1
Quality of the internal auditor = medium - Score 2
Quality ofPrevious audit opinion = qualified - Score 3
Quality of internal financial control = poor - Score 1
Quality of internal financial control = poor - Score 1
It is an urban local government = urban - Score 1.5
TOTAL SCORE - 14.5
The staff and time spent at each local government is then guided by the following:
High risk - score of 14 to 16.5 - three week visit and/or four auditor team
-
7/30/2019 Lagos Audit Manual - Part One
16/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
Medium risk score of 6 13 - two week audit visit (three auditor team)
Low risk score of 5 or below - one week audit visit (three auditor team)
Thus the example above with a total score of 14.5 would be considered high risk and sodeserve a three week inspection with four auditors (including the team leader).
As a result of a low overall assessment of risk, a reduction in substantive testing sample sizesmay be appropriate (see Chapter 4 Performing Audit Inspections). This will allow the auditto be completed in less time.
3.3 Operational Team Planning
Operational Team Planning involves planning for audit visits to individual local governments.This is undertaken by the relevant Zonal Coordinator and the Team Leader reviewing thePermanent Audit File and holding discussions with the Team Leader responsible for the localgovernment in the previous quarter.
The week before the quarterly inspection audits are due to start, the Zonal Coordinators writeto the local governments of their zone to introduce the next audit team and propose the timeof theAudit Entry Meeting.
The object ofOperational Team Planning is to identify issues which impact upon the approachto the audit inspection and which could influence the audit strategy and audit judgments. Theinitial review should normally involve consideration of the following:
Previous quarters audit report
Outstanding issues from the previous quarter
Correspondence/knowledge of events since the previous audit
The level of action taken by the local government on the findings from the previousquarter.
Each local government is visited for an audit inspection during each quarter. The audit teamsconsist of a Team Leader and two or three auditors. The audit teams are rotated so the TeamLeaders and other auditors visit a different local government in each quarter. In addition, theaudit teams are rotated so that the Team Leaders supervise different staff each quarter.
A permanent file is maintained for each local government with the financial statements and theannual audit reports and other vital documentation. A current file is developed for each auditvisit.
A meeting is held before each quarterly visit between the Team Leader for the previousquarter and the Team Leader who will lead the next visit. The Permanent File is reviewed andany outstanding issues are highlighted.
The end product of the planning process is theAudit Planning Sheet(see Annex A to thisChapter). This outlines the strategy for the audit assignment as a whole. The preparation oftheAudit Planning Sheetis be the responsibility of the Zonal Coordinator, supported by Team
Leaders.
The timing of audit planning and the extent of the planning required will vary, depending upon
-
7/30/2019 Lagos Audit Manual - Part One
17/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
the size and circumstances of the Local Government.
Identification of Auditable Activities
The core of the operational audit planning process is deciding what to audit from the manysystems and activities of the local governments. This requires good knowledge of the LocalGovernments business and a high level of professional judgment.
Auditable activities consist of those subjects, which are capable ofbeing defined andevaluated and may include:
Systems such as revenue, purchasing, payments etc
Cashbook, Departmental Expenditure Vote Account (DEVA)
Major contracts and projects
Financial Statements.
Auditors should be encouraged to use their judgment in the field to determine whether aparticulararea needs to be audited, considering any information that might come to theirknowledge during theiraudit visit. However, this should be discussed with the Team Leaderand perhaps the Zonal Coordinator.
For a typical local government the following systems and processes should be subject to auditverification during each quarterly inspection audit visit:
CASH & BANK ACCOUNT
Cash and bank accounts
Cash receipts treasury receipts, bank tellers, bank statements
Cash book payment vouchers, cheques, bank charges
CASH COLLECTION SYSTEM
Revenue receipts
Departmental Vote Revenue Account (DVRA)
Different revenue streams statutory allocations, state grants (including project funds),internally generated revenue, LASSA, Wharf fees and Land Use Charges
Controls over revenue receipt books
DIRECT BANKING SYSTEM
Bank tellers and bank statements

A more complete list of systems, activities and auditable objects may be found in theAudit
Guide in the Annex to Chapter 4.
Production of theAudit Planning Sheet
In preparation for the quarterly planning meeting between the Zonal Coordinator, Team
Leader and other team members, the Team Leader may develop a draftAudit Planning Sheet
(see Annex A to this Chapter). This details the work that will be undertaken at a specific local
government for a particular quarter. It forms the basis for the allocation of audit work to each
of the team members at the quarterly meeting.
This document sets out the details of each audit assignment, including the objectives and
notes of any issues forthe auditor to consider. The purpose oftheAudit Planning Sheetis to
ensure that the exact terms and details of the audit have been agreed and understood by all
members of the audit team. Management at the local government will be asked to provide
comments on the document so that any thoughts orconcerns can be built into the audit at this
stage of the planning process, thus ensuring that the mutual benefit of the complete audit
procedure will be maximised. The document must be agreed and authorised prior to
commencement ofthe audit work on site by the Zonal Coordinator/Team Leader, and must be
retained in the currentfile at the end of the audit.
Auditors should also consider undertaking the following background research where deemed
necessary. It should be clearly noted that this list is not exhaustive:
Reviewing LGA minutes;
The 'Financial Memoranda'
Any relevant legislation;
Any LGA policy documents
Other documentation considered relevant and appropriate to the audit e.g. code of conduct for
councillors and officers.
Therefore, the purpose of producing anAuditPlanning Sheetis to provide:
A well constructed plan encompassing the scope of an assignment to achieve theaudit objectives
A basis for assigning work to auditors
A record of work done
A comparison of work done with work planned

Lagos State Local Government Audit Manual Version 2.2 December 2012
The basis for a review of the future Audit Team Workload
A means formanagement of the Office of the Auditor General LocalGovernments to supervise each audit adequately and review progress.
TheAuditPlanning Sheet(see Annex A to this Chapter) may require amendment in light of'on-the-job'experience as the audit progresses. If this is found to be necessary, this should be
confirmed with the Zonal Coordinator. Where anAuditPlanning Sheethas been fine-tuned
during the course of an audit, this must be fully and properly documented, and on completion
of the audit, a final version of theAuditPlanning Sheetmust be produced, authorised (by the
Zonal Coordinator) and retained in the Current File to inform future audits.

Chapter 3: Evaluating and Testing Internal
controls
INTOSAI Auditing Standards state:
3.3 Study and Evaluation of Internal Control
3.3.1 The field standards include:
The auditor, in determining the extent and scope of the audit, should study and evaluate the
reliability of internal control.
The following paragraphs explain internal control as an auditing standard.
3.3.2 The study and evaluation of internal control should be carried out according to the typeof audit undertaken. In the case of a regularity (financial) audit, study and evaluation are
made mainly on controls that assist in safeguarding assets and resources, and assure the
accuracy and completeness of accounting records. In the case of regularity (compliance)
audit, study and evaluation are made mainly on controls that assist management in complying
with laws and regulations. In the case of performance audit, they are made on controls that
assist in conducting the business of the audited entity in an economic, efficient and effective
manner, ensuring adherence to management policies, and producing timely and reliable
financial and management information.
3.3.3 The extent of the study and evaluation of internal control depends on the objectives of
the audit and on the degree of reliance intended.
3.3.4 Where accounting or other information systems are computerized, the auditor should
determine whether internal controls are functioning properly to ensure the integrity,
reliability and completeness of the data.
3.1 Key Requirements
The key requirements of this chapter are:
Key internal controls should be identified and tested
Key internal controls should be evaluated to decide whether we can rely on them andso avoid the need for 100% substantive testing
The results of testing key controls should be discussed with the Zonal Coordinator andthe strategy for sampling of transactions agreed and documented in the Current File.
3.2 Responsibility for Internal Control
-
7/30/2019 Lagos Audit Manual - Part One
24/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
It is the responsibility of the management of local governments to keep complete and accurate
operational and accounting records, which assist in:
Controlling departmental activities
Safeguarding assets
Preventing ordetecting errors, frauds or other irregularities
Preparing financial statements
Complying with legislation
Achieving the local governments objectives.
Management therefore needs to maintain internal controls designed to ensure the
completeness and accuracy of records and the validity and reliability of the entries they
contain.
The internal control procedures are documented in the Financial Memoranda for Local
Government(current edition 1998) and the Guidelines on Administrative Procedures for Local
Governments (2011).
Limitations on the Effectiveness of Internal Control
Any system ofinternal control is always subject to the possibility of errors. No internal financial
control structure, however elaborate, can guarantee efficient administration, completeness
and accuracy of records or be full-proof against fraud; especially when those holding positionsof authority or trust are involved.
For instance, in the following situations, internal control measures will prove to be ineffective:
segregation controls are avoided by collusion between officials
authorisation controls are abused by those who sign payment vouchers
management (for example, the Chair or Council Treasurer) over-ride key internalcontrols
selection and training may improve the competence and integrity of personnel operatingthe system, but these qualities may change due to pressures exerted from within oroutside their working environment
errors occur due to fatigue of staff, misinterpretation of regulations, carelessness ormisunderstandings.
The Auditor's Use of Internal Control
The auditor's objective in evaluating and testing controls is to determine the degree ofreliance

25/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
that may be placed on the accounting and other controls. If the auditor is reasonably assured
that the internal controls are effective, the extent of compliance and substantive tests may be
reduced and 100% vouching may not be necessary. However, due to thelimitations in any
system of internal control, it will always be necessary to perform some substantive testing.
3.3 Types of Internal Control
The following are some examples of types of internal control:
Organisational control- The organisation chart structure for LGAs is uniform. Iteffectively defines and allocates responsibilities, reporting lines, delegation ofresponsibilityand authority. To back this up, Local Governments also have in place a schedule ofAuthorised Signatories.
Segregation of duties - This is separation of duties orresponsibilities that would, ifcombined by one individual, enable that individual to record and process a complete
transaction. Segregation reduces the risk of manipulation or error and increases the degreeofchecking as the work of an officer checks oris complementary to that of another. As a rule,separate officers or sections should be responsible for the following tasks:
authorisation of local purchase orders or payment vouchers
receipt or custody of the goods or services
maintenance of the purchase ledger, cash book and other accounting records.
Physical controlSuch controls are primarily concerned with the custody ofassets andinvolve procedures and security measures designed to ensure that access to assets is limited
to authorised personnel.
SupervisionAny system of internal control must include supervision of the routinetransactions and operating procedures by responsible officers.
Authorisation and approvalAll transactions require authorisation orapproval by anappropriate, responsible officer.Authorisation limits have been established via the FinancialMemoranda for local Government (1998).
Arithmetic and accountingThese controls operate within the recording function tocheck that transactions to be recorded and processed have been authorised and are completeand accurate. These controls include checking arithmetical accuracy (recomputing/casting),
maintaining and checking reconciliation statements, document sequence and count checks.
PersonnelLagos State Government has put policies in place to ensure that a formalprocess has been established to assist and encourage personnel with Accounting andAuditfunctions to attain the necessary capabilities to fulfill the responsibilities of theirposts. It is afact that the properfunctioning of an operational and/or financial system depends on thecompetence and integrity of those operating it, and therefore qualifications, selection, trainingand the personal characteristics of officers involved are important features to be considered inestablishing any control mechanism.
Identification and Evaluation of Key Controls
A review of the accounting and internal control systems should be performed to identify the
keycontrols, which exist to prevent or detect material misstatements. .
-
7/30/2019 Lagos Audit Manual - Part One
26/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
Key controls are those controls, which are integral to the effective system as a means of
preventing ordetailing material misstatements. By identifying and testing the key controls, it is
not essential to test all the internal controls in a system. Controls will often relate to the
authorisation ofa transaction, or the evidence of review of a process.
A list of some of the key internal controls in local governments is included as Annex A to thisChapter.
As a result of identification and evaluation of key controls, the level of risk of each of the
systems/activities subject to audit testing should be assessed. Considerations, which
influence the level of risk will include, for example:
The control environment are key controls applied? Is internal audit well performed?
The nature and amount of the transactions and balances involved what is thequarterly level of revenue and expenditure?
The results ofthe previous audits an adverse audit opinion (not true and fair) willresult in high risk and 100% substantive testing.
The nature of any changes to the accounting and internal control systems since theywere previously tested.
Vacancies of key staff, for example, second signatory.
3.4 Tests of Control (compliance testing)
Tests ofcontrol are performed to obtain audit evidence that the key controls on which relianceis sought operate effectively. This means that the controls exist and have effectively operated
throughout the reporting period.
By testing the identified key controls it is not necessary to test all the controls present in the
system as these provide the controls, which are integral to the effective operation ofthe
system.
Tests of control may include:
Corroborative enquiries (third party confirmations) about, and observation of, internal
control functions
Inspection of documents supporting controls or events to gain audit evidence thatinternal controls have operated properly, for example verifying that a transaction hasbeen authorised ora reconciliation has been approved
Examination of evidence that management has carried out its own reviews, forexample minutes of Executive Committee meetings at which audit reports arereviewed and correctiveactions decided on
Re-performance of control procedures, for example reconciliation of bank accounts, toensure they were correctly performed by the responsible officer
When collecting evidence about the effective operation of internal controls, relevant
considerations are:
-
7/30/2019 Lagos Audit Manual - Part One
27/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
How they were applied?
Were consistency applied during the period?
Who applied them?
If a deviation is identified, specific enquiries must be made to identify whether the deviation
was isolated (these enquiries may include additional testing) and whether there were any
effective alternative sources of control during the period. Provided that the additional testing
confirms that the deviation was isolated or that a mitigating control proved effective, reliance
can still be placed on the effective operation of the control before and after the period of
deviation.
If errors or weaknesses are identified in the control system the risk of the specific audit area
should usually be revised as follows:
Original level of risk 1-3 errors 4 or more errors
Low Increase to medium risk Increase to high risk
Medium Increase to high risk Increase to high risk
The effect of these revisions may be to increase level of substantive testing by increasing the
sample sizes.
The output of testing the key internal controls will be an assessment of the audit risk for each
of the major systems which are subject to audit. In each case the system should be assessed
as being of high medium or low risk. This risk rating will act as a guide to the level oftransaction/substantive testing that is to be undertaken and may be documented in the form of
a table as follows:
System/activity Risk
assessment
Comments
Cash book High
Revenue and Expenditure Abstracts Low
Vote books Medium
Federal Government Grants Low
Continued
This risk rating should be documented in the Current File and be signed off by the Zonal
Coordinator.

28/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
3.5 Sample Sizes for Transaction Testing (substantive testing)
Transaction testing may be reduced where the key internal controls have been found to be
operating reliably over the period covered by the audit. In this case sample sizes for
substantive testing may be adjusted as follows:
Level of risk Sample size
High 100%
Medium 100% above say N100,000
and 50% below this level
Low 100% above say N100,000
and 25% below this level
Ajustification for the reduced level of substantive testing must be included within the planningmemorandum. In addition, care should be taken that contracts etc are not split into several
payments to ensure that transaction is subject to a reduce likelihood of being tested.

Chapter 4
Performing Audit Inspections
INTOSAI Auditing Standards state:
3.2 Supervision and Review
3.2.1 The field standards include:
The work of the audit staff at each level and audit phase should be properly supervised
during the audit, and documented work should be reviewed by a senior member of the audit
staff
The following paragraphs explain supervision and review as an auditing standard.
3.2.2 Supervision is essential to ensure the fulfilment of audit objectives and the maintenance of the
quality of the audit work. Proper supervision and control is therefore necessary in all cases, regardless
of the competence of individual auditors.
3.2.3 Supervision should be directed both to the substance and to the method of auditing. It involves
ensuring that:
(a) the members of the audit team have a clear and consistent understanding of the audit plan;
(b) the audit is carried out in accordance with the auditing standards and practices of the SAI;
(c) the audit plan and action steps specified in that plan are followed unless a variation is authorised;
(d) working papers contain evidence adequately supporting all conclusions, recommendations and
opinions;
(e) the auditor achieves the stated audit objectives; and
(f) the audit report includes the audit conclusions, recommendations and opinions, as appropriate.
3.2.4 All audit work should be reviewed by a senior member of the audit staff before the audit
opinions or reports are finalised. It should be carried out as each part of the audit progresses. Reviewbrings more than one level of experience and judgment to the audit task and should ensure that:
(a) all evaluations and conclusions are soundly based and are supported by competent, relevant and
reasonable audit evidence as the foundation for the final audit opinion or report;
(b) all errors, deficiencies and unusual matters have been properly identified, documented and either
satisfactorily resolved or brought to the attention of a more senior SAI officer(s); and
(c) changes and improvements necessary to the conduct of future audits are identified, recorded and
taken into account in later audit plans and in staff development activities.

4.1 Key Requirements
The key requirements of this chapter are:
All audit work should be adequately planned and anAudit Planning Sheetcompleted
Letters of commencement and introduction should be sent on time
A suitable Entry Meeting should be held and minuted
Key internal financial controls should be documented, evaluated and tested
A suitable level of substantive testing should be undertaken in line with the audit guide
A suitable Exit Meeting should be held and minuted with the Team Leader and ZonalCoordinator in attendance
The Inspection Report should be reviewed by the Zonal Coordinator and signed off bythe Director of Evaluation & Reporting
Follow-up and post-audit review should be undertaken.
4.2 Preparation for an Audit
Planning is critical to the success of each audit assignment. The aim is to ensure that the
planned work will efficiently satisfy the audit objectives.Adequate time must be set-aside for
this stage, which identifies priorities, objectives, and allocates staff time to each activity.
The Team Leader will undertake the preparation for an audit including the development of
Audit Planning Sheet, with input from other team members and authorisation by the Zonal
Coordinator.
Research
It is essential for auditors at this stage to gain a good understanding of the local government
and its operations. Sources ofinformation will include, but not necessarily be limited to:
Audit report for the previous quarters inspection visit
The Permanent File, Current File and working papers (including the extraction offollow-up points from the previous quarter audit inspection)
Reference Library
Relevant legislation (see Appendix A)
Reports to Public Accounts Committee (Local) of the State House of Assembly
Financial and any other relevant regulations in addition to the FinancialMemorandaand the Guidelines on Administrative Procedures for Local Governments
Previous years financial statements and report of the Auditor General for LocalGovernments
-
7/30/2019 Lagos Audit Manual - Part One
34/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
Financial statements for the previous months/quarters for the current financial year
Organisation charts and contacts for key staff at the local government.
At the end of this stage, the auditor will be in a position to form a view about:
Systems boundaries orlimitations
Identification and assessment of risks
Identification of key personnel staffing structures and reporting lines.
4.3 Phases of Audit
Quarterly inspection audits will generally consist of eleven phases, with supervisory review
occurring at appropriate intervals:
Letter of Commencement sent by the Head of Evaluation & Reporting informing thelocal government of the audit (about a month before the start of the audit)
Letter of Introduction from the Zonal Co-ordinator or the Team Leader (about a weekbefore the start of the audit
Development ofAudit Planning Sheet
Entry meeting
Evaluation of internal controls
Substantive testing
Exist meeting
Report of the Inspection Audit
Response from the local government and appraisal of the response
Follow-up
Post-audit review.
4.4 Commencement Letter
Approximately a month before an audit is scheduled to begin, the commencement letter will
be sent by the Director of Evaluation and Reporting to the Chair of the LGA being audited and
copied to the members of management who may be affected by the audit. The letter will notify
them of the assignment and it will indicate that an entrance briefing will be conducted prior to
the audit. A point of contact and phone number of the audit office will be Included.
4.5 Letter of Introduction
A telephone call by the Zonal Coordinator (or introductory letter) should follow the planning.
-
7/30/2019 Lagos Audit Manual - Part One
35/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
This will schedule an entrance meeting to begin the exchange ofinformation that will be
needed during the audit.
4.6 Audit Entry Meeting
At the start of the audit visit an entry meeting is held by the Zonal Coordinator and Team
Leader with key officers and management staff of the local government including the
following:
Executive Chair
Council Manager
Council Treasurer
Heads of Department.
This agenda for this meeting should include:
introduction by the team leader
outstanding issues from the previous audit
information from the Office of the Auditor general for LocalGovernments
objectives of the exercise
significant developments at the local government
providing documents and records that will be needed for the audit (previously listed inthe Directors letter).
The entry meeting ensures that management of LGA endorses the audit and allows the
auditor to obtain critical information for the audit brief, as well as demonstrating common
courtesy.
The meeting will establish, among other things:
Audit and local management concerns
Client expectations in relation to the outcome
Any obvious local management and/or audit or operational issues arising at thisstage, which might impact on the work to be undertaken
Any known or perceived current and future pressures facing the audit.
It will confirm the auditor's understanding of systems boundaries and objectives and will
establish:
The best timing forthe audit for both the LGA and the Audit Team
The key contact(s) within the authority
The audit closure arrangements and interim/final reporting lines
During the entry meeting, the audit Zonal Coordinator/Team Leader should explain the audit
process, identify departmental heads' concerns and suggestions for objectives, and generally
-
7/30/2019 Lagos Audit Manual - Part One
36/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
open the channels of communication that are necessary fora successful engagement. The
other members of the audit team should also attend this meeting.
Formal minutes should be documented for the Entry Meeting and copies sent to all the
officials who attend.
4.7 Evaluation of Internal Controls
Auditors should identify and evaluate the key internal controls for each of the financial
systems which they review (see the checklist in Annex A to Chapter 3). The key internal
financial controls should then be tested to ensure that they are operating reliably over the
period subject to audit. Substantive testing may be reduced, with the use of audit sampling,
where the internal controls are operating reliably (see Chapter 3 for more details).
The reliance levels are interpreted below:
High control riskarises if controls are weak orif no reliance is to be placed upon the internal
system and no tests of control are to be performed. 100% substantive testing should be
introduced.
Medium controlriskmay be applied to an audit area where some internal control features
exist on which reliance can be placed although strong controls cannot be applied to all
aspects of the audit area. Reduced testing my be appropriate if agreed by the Team Leader
and Zonal Coordinator.
Low control riskis appropriate ifa strong and reliable internal control system appears to exist
and their reliability is confirmed by testing of the controls (for example, that proper bankreconciliations are undertaken each month and reviewed by the Council Treasurer). Audit
sampling of transactions (payment vouchers etc) should be agreed with the Team Leader and
Zonal Coordinator.
Control Recommendations
If the internal financial controls are not operating properly and reliably, specific
recommendations should be developed to introduce the required controls. These
recommendations should be reviewed by the Team Leader and Zonal Coordinator, reported at
the exit meeting and included in report of the inspection visit.
4.8 Substantive Testing
Substantive tests are performed to obtain sufficient and appropriate audit evidence that the
transactions and balances are accurate, authorised and regular. They are also necessary to
identify any possible errors, mistakes or irregularities.
Substantive tests include analytical review, observations and enquiry (e.g. the confirmation
that a staff list is accurate by tracing employees), re-computationsand inspections (e.g.
physical inspection ofitems in store).
Substantive tests of details are often the most appropriate way to test compliance with
relevant laws and regulations.
-
7/30/2019 Lagos Audit Manual - Part One
37/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
Level of Substantive Testing
The number ofsubstantive tests may be reduced where tests of control provide satisfactory
evidence as to the effectiveness of the internal financial control systems. However, a minimum
level of substantive tests should be performed for each material class of transactions and
balances.
Audit sampling is described in Chapter 3.
Audit Query
Audit queries may be raised by staff of the Office of the Auditor General for Local
Governments, but queries may also be raised by the internal auditor of a local government,
the Council Treasurer or the Council Manager. If they are over-ruled by the Chair of the local
government they should be referred to the Audit Alarm Committee (if it exists) and the Office
of the Auditor General for Local Governments.
Schedules 1 and 2 of the Guidelines on Administrative Procedure for Local Governments
(2011, pages 44-46) details the irregularities or offences which may result in an audit query
being issued, the time limit for a reply to the query and the sanctions which are to be applied.
If an audit query is needed to be raised during an audit, the Team Leader should discuss the
issue with the Zonal Coordinator. The Zonal Coordinator should review the relevant sections
of the file and initial and date them. The audit query is written and signed by the Team Leader
and sent to the Executive Chair with a copy to Council Treasurer or other head of department
who is responsible for the particular area.
The audit queries are reported during the Exit Meeting (see below) and copies are also sent
with the Audit Inspection Report and signed off by the Head of Evaluation and Reporting.
4.9 Exit Meeting
Auditors should keep management informed of how the audit is progressing and discuss
possible findings as these are identified throughout the audit. This practice helps ensure that
the results of an audit are accurate. It promotes a team approach by actively involving local
government management in developing solutions to issues identified by the auditors. Early
discussion of possible findings also allows local government management to begin to
introduce any corrective action that is needed.
At the end of the audit fieldwork, an Exist Meeting should be held with the senior management
of the local government. At this meeting the Team Leader or Zonal Coordinator will review the
work of the audit team and provide details of all audit queries and other audit findings. The
local government management may provide responses at this stage or after they have
received the formal written Audit Inspection Report and a written copy of any audit queries.
The following officials will attend the Exist Meeting:
Executive Chair
Council Manager
Council Treasurer
-
7/30/2019 Lagos Audit Manual - Part One
38/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
Heads of Department
Zonal Coordinator
Team Leader.
The other members of the audit team should also attend this meeting.
Formal minutes should be documented for the Exit Meeting and copies sent to all the officials
who attend.
4.10 Audit Inspection Report
After the fieldwork' for the quarterly inspection audit is complete, a written Audit Inspection
Report will be prepared and issued using the Office of the Auditor General for Local
Governments standard format. This report will include an overall opinion and provide details
about any significant issues, or findings, identified during the audit. Findings should be
presented by identifying the issue, describing the risks and the corrective action to be taken by
the local government.
The Audit Inspection Report should include detailed recommendations to improve internal
financial control, details of any irregularities identified and any audit queries raised should be
sent with the report. Any audit opinions or conclusions should be justified with clear evidence
from the audit testing.
The AGLG or the Director of Evaluation and Reporting signs routine reports for audits. These
will be issued to the Executive Chair, Council Treasurer and Council Manager (with the fourth
copy for the audit file). These officials are in a position to take corrective action or ensure thatany necessary changes are made by drawing the attention of other heads of department are
necessary.
A formal written response to the Audit Inspection Report should be received within two weeks
of the Exit Meeting.
Response from the local government and appraisal of the response
Procedures that should occur, as the audit is wrapped-up include:
Doing an overall review of the working papers to see that all procedures are complete,working papers are signed-off
Comparing the planned and actual completion dates and providing explanations forany material variances
Reviewing the result of the audit planning and lessons for future inspection visits
Submitting the working papers for filing.
Some of the above tasks may be combined with a post-audit review when the Director of
Evaluation and Reporting, the Zonal Coordinators and the Team Leaders will review the
results of the quarterly inspection audits to ensure that they were completed as required and
the necessary steps are taken for future audits.

39/83
Lagos State Local Government Audit Manual Version 2.2 December 2012
4.11 Follow-Up
The Director of Evaluation and Reporting will follow-up to ascertain that appropriate action is
taken on reported audit issues and findings. Follow-up is a process by which auditors
determine the adequacy, effectivenessand timeliness of actions taken by local government
management on reported audit findings.
The Director of Evaluation will determine the nature, timing and extent of follow-up and
Reporting, to be completed usually within one year ofissuing the final report or shortly after
the last completion date formanagement's action plans has occurred.
Auditors will determine what corrective action was taken and ifit is achieving the desired
results.
4.12 Audit Control and Review
In orderto ensure consistency and compliance with professional standards and audit
procedures, it is essential that all audit work is effectively overseen at all stages of the
process. The audit files and reports should be reviewed and signed offby the Team Leader
Zonal Coordinatorat each stage and particularly before the Exit Meeting and again before the
audit report is issued.
This process is designed to ensure that:
All work undertaken complies with the requirements of this manual and professionalgood practice
Work programmes are completed unless deviations are bothjustified by thefindings ofthework undertaken and authorised by the Zonal Coordinator
Audit files are complete and properly structured
Appropriate audit techniques have been used
All working papers adequately support the findings, conclusions andrecommendations of the report to which they relate
The related audit report is complete, accurate, objective, clear, concise, constructive
and timely
The objectives of theaudit assignment are met within the allocated time budgets orappropriate time variations were authorised.
The Zonal Coordinator's overseeing of the audit must be evident from the working papers. The
audit management review process must be evidenced by the reviewer initialling and dating the
appropriate working papers. Issues raised during the review process should be adequately
recorded and cleared before final sign-off.

4.12 Post Audit Review
In April to June each year a post audit review is undertaken by the Director of Evaluation and
Reporting. This reviews the inspection visits of the four quarters of the previous years,
considers the quality of the work which was undertaken and documents any lessons to be
learnt for future years.

AUDIT PROGRAMMES & CHECKLISTSThese audit programmes and checklists provide comprehensive guide
for carrying out routine examination of accounting books and records,procurement, verification of projects and financial statements inroutine field audit work.
SECTION I: MAIN BOOKS OF ACCOUNT
A - Cashbook
1. Main Activities Involved
The cashbook is the main analytical book where each money received or each
amount paid is recorded.
2. Control Objective
To ensure that the receipts and payments made by the local government are
correctly recorded as provided for by financial memoranda chapter 19.
3. Risks
The risk for inaccurate cashbook postings is that the actual receipts or
payments may be under or over stated thereby rendering the account balances
at the end of a reporting period unreliable.
4. Records Required at Audit

1. Post all payment vouchers on the credit side of the cashbook.
Post all receipt vouchers on the debit side of the cashbook.
2. Record any unpresented payment or receipt voucher and consult the cashier for its whereabouts
3. Where deductions are made on payment or salary voucher and the payment is made by cash, the gross amount
must be entered as the payment in the cash column on the credit side and a treasury receipt must be made out
for the deduction which is then entered as a receipt in the cash column on the credit side of the cashbook.
4. Ensure that when a cheque is drawn to obtain cash from the bank, the amount of the cheque will be entered in
the bank column on the payment side of the cashbook and if the cash is received in the Treasury on the same
day, the identical amount shall be entered in the cash column on the receipt side if the cashbook. These two
entries should be marked as contra
