HA3032 Auditing  Group Assignment Specifications


The aim of this group assignment is to provide you with an opportunity to design a “risk- based” audit program for a real world company and focus on the “Substantive tests of balances”, which involves substantiating the ending balance of an account(s), which is comprised of multiple transactions, as at a certain year-end date.

Assignment Requirements and Structure

  1. Students are required to form groups of 4 students group members by completing the “HA3032 Group Form details”.
  2. Each group of students group have been provided by unit coordinator, a unique ASX listed company to use for progressive analysis in this group assignment.
  3. Prepare a detailed audit program Report [3,000-3500 words] for the client/company in a group of 4 students. Students must use a Report Format with an Executive Summary and Table of Contents.
  4. Use publicly available online resources for research purposes.

Detail Assignment Tasks: Developing an Audit Program for a selected listed Company

  1. Gain an understanding of the nature of the entity and its industry and then identify key business risks. After this is completed, assess where the risks of material mis- statements could be in the financial report. Consider the factors affecting both Inherent Risk and Control Risk. Finally, apply the Audit Risk Model [AR = (IR, CR, DR)] to the selected company. Which risk rating would you apply (Low, Medium or High) to the company’s inherent risk assessment and control risk assessment? How does this affect your assessment of Detection Risk and Audit Risk?
  2. Perform analytical procedures of the Statement of Financial Position and of Financial Performance over the last three years using appropriate ratios and/or metrics. Select four key ratios and provide a brief explanation in the report. This should be presented in a table format.
  3. Discuss with your group members which account balances are considered “material”. Explain how you calculated materiality for planning purposes and provide appropriate justification for your decision-making.

(Note - Use a table format to structure your answers to questions 5, 6, 7 & 8)

  1. Select up to ten different material account balances, at least five assets and five liabilities.
  2. For each material account balance selected, list the relevant financial report assertions and explain why the selected assertions are applicable to each account.
  3. Design a comprehensive set of audit work steps for each material account balance, which addresses the selected assertions and which will result in sufficient and appropriate audit evidence being collected for your selected client company. (Assume that a predominantly substantive approach is being adopted)
  4. Include a sampling plan, which details how you will use sampling for each material account balance to be tested. How many items will be tested for each test?



Development of an audit program


The word “auditing” has been derived from the word “audire" which has a meaning "to hear". Traditionally auditing is to examine accounting records for establishing a view that accounts reported all transactions correct in books of accounts for the desired purpose but now in addition to this auditor also required to express an opinion on the financial statements that weather the accounts pottery a true and fair view or not. Financial statements are a set of documents that show the result of any business operation for a particular period and correct value of assets and liabilities as on date. So with the view of the above thing, one must clear that books of accounts should be true & fair. However, the statement of accounts is assessed by various stakeholders such as creditors, investors, bankers, owners' government tax authorities, etc all of them have different angels different interests regarding financial statements. So a statement primarily made for the interest of owners can change the decision of various stakeholders in favor of owners. So for protecting the interest of various stakeholders an independent examination system should be there to check the authenticity of the financial statements, such examination is conducted by the auditor and such examination is called an audit (PWR holding limited, 2020).

To perform audits an auditor needs to conduct some audit procedures to know the authenticity of the financial statements. Audit procedures are the scientific methods used by the auditor for simplifying conducting the audit.some of the audit procedures are sampling, assess the risk of material misstatement, third party verifications (PWR holding limited, 2020).

In the current assignment, we get to know all information an auditor requires and use for conducting an audit that how he makes an audit plan in which he assesses the risk of material misstatement, how to audit procedures are selected and applied to various accounts. In the current report, we take "PWR holdings limited" as a corporate entity on which we read the concepts of auditing "PWR holding limited is a leading company that provides world-class cooling solutions by manufacturing refrigerators (PWR holding limited, 2020).

Company and Industry analysis

PWR holding limited is involved in manufacturing, design, engineering testing, and sale of cooling products to the motorsports automotive equipment manufacturing and aftermarkets in domestic as well as international markets. The company has its registered office at 103 Lahr's Road, Ormeau, Queensland 4208 (PWR holding limited, 2020). This company has its business operations in Australia, the UK, the USA, Italy, and several other countries. Most of the business of PWR holding limited is comes from the countries in the UK and the USA (PWR holding limited, 2020). PWR holding limited work in the refrigeration industry, which design radiators, inter-coolers for the global motorsports industry. Motorsports industry is a huge industry now a day’s motorsports activities required high power engines which getting hot very easily so for cooling down them they require coolant and refrigerators for those engines. PWR holdings limited is a market leader in this regard it has a consolidated turnover of $36955000 for the financial year ended on 30 June 2019. The main specialization of PWR holdings limited is in providing a customized cooling solution (PWR holding limited, 2020).

Risk of material misstatements  

It is the auditor’s responsibility to assess and identify the risk of material misstatement in the financial statements through understanding the organization and the environment in which such organization works and internal control of the organization. The risk of material misstatements means assessing that part of financial statements in which any misstatement made a material effect on the authenticity of the financial statements. Mainly such areas are cash, Inventories, provisions (Lu, Simnett, & Zhou, 2019).

Audit Risk Model a detailed analysis 

According to the audit risk model:


Where AR = Audit risk

IR = Inherent risk

CR = Control risk

DR = detection risk

  1. Inherent risk – It is the risk of misstatement at the level of account balance or class of transaction, assuming that there were no related internal controls are there in the organizations (Lu, Simnett, & Zhou, 2019).Any external circumstances giving rise to business risk also increase inherent risk. In PWR holding limited inherent risk is high because of changing technology there are high chances that any star product can be obsolete shortly. 
  2. Control risk – It is the risk of a misstatement that occurs when about a class of transaction and account balances, will not be detected, corrected, controlled or prevented, by the internal controls of the organization. PWR holding has high internal controls so there is moderate control risk there for any material statements in the financial statement of PWR holding limited (Lu, Simnett, & Zhou, 2019).
  3. Detection risk – Detection risk is a risk that any misstatement which could be a material statement will not be detected by the audit procedures applied by the auditor. Detection risk is purely depending on the auditors of PWR holding limited but as it is a complex industry then detection risk is also moderate. 

Any misstatement can be material either individually or aggregate with other misstatements. The audit risk model is used to understand various audit risks involved in the procedures applied by the auditor. Apart from this, audit risk model is used to identify audit risk and use audit procedures to establish a true and fair view of the financial statements.

Analytical Procedure of Financial position of the company:

The comparison of various financial and operational information of the company for analyzing financial and non-financial positions is referred to as an analytical procedure. The analytical procedure gives an understanding of organization business and the impact of the market trend on organization business. For doing analytical procedures multiple types of ratios are calculated for different fiscal years. The four key ratios that are calculated for doing analysis are as follows:

  1. Liquidity Ratios: These ratios provide an understanding of the liquidity of the company means how the company operates its current assets against current liabilities. Liquidity ratios are the current ratio, acid-test ratio, cash ratio, and operating cash flow ratio. However, 1.2 has been maintained which reveals higher cash blockages in its current assets. 
  2.  Profitability Ratios: These ratios provide an understanding of company profitability against investment in the company. By these ratios, the company's performance is analyzed under different market situations. Profitability ratios are gross profit margin, net profit margin, EBITDA ratio, return on capital employed, return on equity, and return on assets (Lu, Simnett, & Zhou, 2019).
  3. Efficiency Ratios: By these ratios, company ability is measured that how efficiently the company able to manage inventory against different account balances of financial statements. Efficiency ratios involve inventory turnover ratio, total assets turnover ratio, fixed assets turnover ratio, debtors turnover ratio (PWR holding limited, 2020).
  4. Solvency Ratios: By these ratios, the company's ability is measured in respect of repayment of debt obligation, and to analyze cash flow is sufficient to meet short and long term debt obligations. Solvency ratios are debt-equity ratio, total debt to total assets ratios, interest coverage ratios, and proprietary ratio. 

Concept of materiality and account balances consider as material in PWR holding limited:

Materiality means information on financial statements that have an impact on the decision of investors if it is disclosed in front of investors. In the process of audit, an auditor can't perform audits on every aspect of financial statements due to various limitations such as limitation of time, limitation of manpower, limitation of cost, etc. Therefore for performing audits, auditors used the concept of materiality and set up a limit up to which transaction or account balances are not material, and above that, they are material that needs to be audited (Mock, et al. 2018).

There is always a materiality risk while performing audits due to the underestimation of inherent risk, control risk, and detection risk. The material level is not deciding on an estimation basis, it is calculated on a qualitative and quantitative basis after doing proper calculation and analysis of the organization business. An auditor can change the level of materiality at any time during the audit procedure (Schmidt, et al. 2016).

In the case of PWR holding limited materiality, the level is determined based on assets and liabilities, income and expenses against revenue. Under this report, the analyst took 3% of revenue as the material level of organization business transaction and account balance.

Materiality level of PWR holding limited is:$51889 * 3%=$1556

Therefore in the case of PWR holding limited material level for performing audits will be $1500. According to the material level, following assets and liabilities need to audit of financial statement of PWR holding limited: 

  1. Assets:
  2. Cash and cash equivalents:$12110

Plan of Sampling under audit procedure:

Sampling means an activity under audit procedure in which several transactions or accounts are selected for audits that are representing all business transactions of the organization. Under-sampling, a list of selected items is used to observe and analyze of whole organization's business and its nature. Sampling is done at the same time on a random basis and some time on a scientific basis. Before selecting a sample, auditors have conducted a proper understanding of the risk involved in the sample (PWR holding limited, 2020). For auditors, an audit of 100% business transaction is not possible therefore he performs sampling to reduce the time and cost of the audit (Chiang, 2010).

Scientific sampling means for selection of sample use some calculation and reasonable criterion from the financial statement. In case of audit procedure of PWR holding limited, materiality level is used for selection of sample (Chiang, 2010). There is always risk involved in audit due to various limitations and due to the sampling process, this risk increased for auditors. At the time of conducting an audit, if auditors analyzed that audit risk is increased due to the materiality level and selection of samples. Auditors can reduce the level of materiality, apply other methods also for the selection of samples, and increase the size of sampling for audit procedures.

For PWR holding limited, audit procedure is designed as a combination of materiality and sampling. Multiple accounts are selected for audit purpose that represents the overall financial position of organization business and how they operate in a market trend (Braganza, & Desouza, 2016)


After analysis of the above report, it is clear that high professionals are required to conduct an audit procedure of an organization so they can perform an audit efficiently and effectively. The audit is conducted by a combination of various processes and techniques such as sampling, materiality, analytical process, ratio analysis, audit documentation. An auditor needs to design and follow an audit program for performing an audit procedure. A proper record is also needed to maintain that is called audit documentation. The audit procedure applied for PWR holding limited provides reasonable assurance. However, the risk involved in the audit of PWR holding limited is high due to high inherent risk, control risk, and detection risk. By analysis of the financial statement, it can conclude that the growth of PWR holding is good and effective from previous years.
