Model Audit

The practice of ensuring the accuracy of the assumptions contained in financial models

What is a Model Audit?

A model audit is an important task in financial auditing that helps ensure that spreadsheet errors are eliminated. Also called a model review, it is commonly requested by banking organizations in order to make sure that the assumptions contained within their models are accurate, reassuring lenders and investors that the models can be relied upon.

Scope of a Model Audit

A model audit is done in order to make sure that spreadsheet errors are corrected. Thus, it needs to be specific with its scope and purpose to ensure that the relevant tasks are completely and correctly carried out. The audit’s scope includes the following:

  • The audit should successfully review the logic used in the model under scrutiny.
  • An audit should check for the model’s consistency in terms of transactions and documentation.
  • The audit should make sure that the model is consistent and parallel with GAAP and taxation rules.
  • The audit should check for how sensitive the model is.

 

Purpose of a Model Audit

The audit should be able to yield accurate results and the auditor needs to provide an assurance to the party seeking the audit that such results will be obtained. To achieve the audit’s objectives, the auditor offers an amount of liability that guarantees a level of reliance, which may be equal to multiples of the fee. Should there be any mistake in the audit as a result of the auditor’s negligence, the company who requested for the audit can sue the auditor.

Basically, the audit aims to ensure that the financial model used by a business is accurate and that the assumptions contained within it are effective. It confirms or denies that the financial model does what it is expected to do and that any errors are minimal and will not cause any derail or delay of the business’ projects.

 

Categories

There are basically two broad categories – the high-level review and the formal model audit.

 

1. High-level review

A high-level review provides added confidence to clients about the financial model that they are using. Aside from just correcting errors on a spreadsheet, a special feature of the model audit is that it is keener and more sensitive to spotting errors without checking every single detail of the model in question. It makes the process less time-consuming, while still maintaining a very high accuracy of results, and it includes a check of the model’s logic.

 

2. Formal model audit

A formal audit is what stakeholders and investors may require even after the completion of an audit and submission of a report saying that the model is good enough to use. Often, they require an audit that is formal and most comprehensive, and the formal audit satisfies this requirement.

After rigorous checking, a report is submitted, which contains a detailed list of the errors in the model so that the business can solve the issues before its investors take action.

 

Cost and Duration of a Model Audit

The audit is completed usually within one to five weeks, depending on how extensive the review is.

The fee depends on the following factors:

  • Scope of the review
  • Complexity of the model checked
  • Volume and complexity of the documentation to be reviewed
  • The seniority of the staff who does the work

 

How to Conduct a Model Audit

In order to perform the audit, it is important to recognize that a model is produced by using MS Excel spreadsheets and, therefore, contains data, figures, and formulas. The auditors usually conduct a bottom-up review or a cell-by-cell check of every formula. They can also do a “top-down” analysis of the model.
