Audit and Assurance Sample Assignment

Audit and Assurance



The people in today’s era are provided with immense opportunities to invest their money. However, the return that is available depends upon the way the organisation in which money is invested is working. To invest the money available, the investors look for the organisations that present best financial statements. But to get an idea about whether the financial statements are true and trustworthy an external assistance is required. The assistance is in the form of opinion on the financials. The professional providing the opinion is known as auditor. However, to frame such opinion various audit procedures are required to be performed.

These audit procedures include computation of the audit risk model, calculation of ratios to perform analytical procedures, computation of materiality, setting the account balances that are considered material, sampling plan and etc. The current report lays down a complete focus upon the different audit procedures that an auditor inculcates in his audit programme to gain sufficient and appropriate evidence. The entity chosen for the purpose of this report is Resonance Health Ltd. the different audit procedures are being applied on this organisation to provide an idea of how these work practically.


The Resonance Health Company is operating under the health care equipment industry. The location in which the company is situated is Australia. Basically, services and software that relate to non-invasive imaging in medical field are being developed and delivered by the company. This is the main specialisation area of the said organisation. The products developed by the organisation are mainly sourced by the pharmaceutical companies as well as by the clinicians. The use is the management and diagnosis of the diseases prevailing in humans. The company is famous globally and has received commendations from the famous physicians all over the world. Although the company is situated in Australia but it has gained clearance from all regulatory restrictions for US and Europe as well (Resource Base Limited, 2018).


It is analyse that audit risk model is used or designed to identify the inherent, detention, and control risk associated with the audit procedure of organization. However, there are several risk which could not be managed and mitigated by auditors of company irrespective of the assertion test implemented in the audit procedure.

In order to compute the audit risk of the company, we need to multiply detention risk, control risk and inherent risk associated with the financial statement of company. There are following risks are given which might be faced by the Resonance Health Company in its audited financial statements (Resource Base Limited, 2018).

The inherent risk of the Resonance Health Company would be determined high as there is chances that company have high misstatement in its financial statement due to its increased complexities of the financial statements.

The control risk of company would be moderate as company may face issues in identifying the reporting and accounting frameworks issues. In case of The Resonance Health Company, control risk would be high as company has been filling its financial statement domestic and internationally (Resource Base Limited, 2018).

In addition to this, detention risk of The Resonance Health Company would also be moderate as there is less chances of the fraud, errors and omission to occur in the financial statements of company. All the accountants are highly experience and faces less issues in preparing the financial statements of company.

The audit risk model is used to identify the audit risk of the audit procedure implemented to evaluate the transparency and true and fair view of the assets and liabilities of the company.

Audit risk model is implemented to assess the audit risk associated with the financial statement of the Resonance Health Company.

Practical implication of the Resonance Health Company

After assessing all the details, it could be inferred that the Resonance Health Company is having high reporting risk and accounting compliance risk. There is chances that company may face issues related to the legal compliance and fraud and errors in its financial statements. The audit risk of the Resonance Health Company would be high as it has higher control and detention risk. The audit risk of company is computed by multiplying control risk, detention risk and inherent risk of the company.

In case of the Resonance Health Company, audit risk would be 10% as it has 36% detention risk, 27.8% inherent risk and 10% control risk.

Computation of the audit risk has been computed as below by using the following formula.

Audit Risk = Inherent Risk x Control Risk x Detection Risk

0.10 = 0.60 x 0.60 x Detection Risk

0.10 = Detection Risk = 0.278 = 27.8%

(Resource Base Limited, 2018).


Analytical procedures provide a better financial as well non-financial understanding about the organisation. These ratios make a calculation among different financial figures and even nonfinancial figures of the organisation. This calculation helps in understanding the trend and direction in which the organisation is moving. If only the financial aspect is seen in the analytical procedures, the main trend calculator way is the computation of ratios. The ratios could be categorised mainly into, liquidity ratios, activity ratios, profitability ratios and solvency ratios.





Current ratio

This ratio shows an insight into the Resonance Health Company’s liquidity. For computing this ratio the formula used is :

Current assets

Current liabilities

The name suggests the use of this ratio. The current scenario’s liquidity is computed by this ratio, i.e. how able the company is at current date to set off the liabilities at current date (Barman, & Sengupta, 2017).




Receivables Turnover

This is an important activity or efficiency ratio. The ratio is calculated by:

Credit sale

Average accounts receivable

This ratio signifies the number of times or the frequency with which the firm makes collection from its debtors during a year (Heikal, Khaddafi, & Ummah, 2014).




Return on assets (%)

This is an important profitability ratio. The calculation is done as follows:

Net income

Average total assets

The ratio represents the return as a percentage of the assets that have been employed in the business to generate that return (Aprisilya, & Mawardi, 2016).




Debt to equity ratio

This ratio helps in computing the level of debt a company uses against the equity which is employed in business (Resource Base Limited, 2018). The formula is

Total debt

Total equity

(Noreen, Brewer, & Garrison, 2014).





When the financial statements of the Resonance Health Company are audited by an auditor, the focus cannot be maintained on every account balance. The audit has to be performed in a limited time span as well as with limited resources. If every account balance gets checked then it becomes too costly and time taking. That is why the auditor at his place has to decide the account balances which shall be checked in detail. However, the selection of the accounts cannot be done hypothetically or without any reasonable basis. The audit tool that helps in selection of such account balances is materiality level (Lakis, & Masiulevičius, 2017).

Materiality, as the name suggests signifies the part that is material, i.e. substantial. This part is so substantial that the decision of the person who knows about this part would be completely different from the one who does not. To compute materiality, the professional judgement of auditor is of utmost importance. However, this judgement has to be applied in calculation of the quantitative level of materiality (Eilifsen, Hamilton, & Messier Jr, 2017).

A series of steps are required to be followed to compute materiality. This involves selection of a stable base that is least volatile. This has to be one among, revenues, net profit, expenses, net assets, etc. For the company Resonance health Ltd the base selected is revenue. When a base account is finalised on the basis of stability, the next part is to compute a percentage of that. The percentage figure for revenue is 2%. After the 2% of revenue is computed, the resultant amount is adjusted by looking on the trends that are shown by the entity’s business. And the final figure that comes is known as materiality of business. In the given net income is ignored for computing materiality because net income had been negative in two preceding financial years and has shown high volatility (Ruhnke, Pronobis, & Michel, 2018).

The materiality amount is:

Revenues: AUD 2,896,395

2% of revenue: 57,928

As the financials are showing instability, the risk in business tends to be higher. Hence the materiality is set at AUD 50,000. Based on this materiality level, all the account balances present in the income statement are checked. The account balances whose amounts reach this level are considered material. These selected account balances are shown below (Resource Base Limited, 2018).

ASA 530, audit sampling, helps the auditor in arranging the selection of items that can form a sample base on which the audit procedures can be performed. This ASA is important to be considered in an audit in the Resonance Health Company because of the certain inherent limitations that revolve around audit function. Considering time and costs constraints, every item of the population comprising account balances cannot be audited by the auditor. To provide a reasonable assurance on the financial statements a sample base has to be selected by the auditor on which he lays his overall opinion. Sampling helps in determining that sample. In the above sections materiality has been calculated for the organisation’s financial statements. Using the materiality level and sampling together, a proper audit can be designed. Many forms are present in which a sample can be designed, but it is always good to go with a systematic or scientific sampling technique (AICPA, 2017).

Scientific sampling works by choosing a sample on the basis of a certain criterion and not according to any non-reasonable selection in financial statement of the Resonance Health Company. In the given situation the materiality level could work as a scientific base, and the items that lie in the materiality level could be used to gather the sample items. However, as far as the number of items is considered that can comprise of the sample size, there is no designated quantity. Everything gets dependent upon the risks that the auditor recognises as the audit commences. If during the audit tenure, the auditor feels that the risks are not too prevalent in the business; a smaller sample size could prove enough to provide sufficient and appropriate audit evidence. However, if the case is opposite, then a larger sample size is highly required (Ussery, et. al 2019).


To base an audit opinion which is reliable in the most appropriate manner, the necessity is to conduct an audit in highly professional manner. Auditor independence is the foremost requirement to conduct any audit procedure properly. The audit evidences that are gathered in the due Assignment of audit must be documented carefully for the use of future purposes. However, audit even if done very properly could not make it certain that account balances are completely free from chances of material misstatements. It is just a matter of provision of reasonable assurance for the financial statement of the Resonance Health Company. The crux of this report is that the Resonance Health Company is having high audit risk due to the high inherent and detention risk. Nonetheless, financial performance of Company is good and effective in market since last five years.
