3.9 Types of Risk
Inherent Risk
The risk that an activity would pose if no controls or other mitigating factors were in place (the gross risk or risk before controls). It is Susceptibility of a business or process to make an error that is material in nature, assuming there were no internal controls.
Inherent risk depends on the number of users and business areas. Higher the number of users and business processes, higher will be the level of inherent risk.
Residual Risk
The risk that remains after controls are taken into account (the net risk or risk after controls).
Residual Risk = Inherent Risk – Controls
For example, a machine costing USD 10000 has inherent risk of USD 10000. Organization took insurance coverage of USD 8000 to safeguard against any damage. So residual risk now is only USD 2000. If an organization's risk appetite is above $2000, then risk is said to be acceptable. If risk appetite is less than USD 2000, then further insurance to be taken to reduce the residual risk. In short, for a successful risk management program, residual risk should be within the risk appetite. When residual risk is within the risk appetite, it is acceptable risk level.
Primary objective of a risk management program is to ensure that residual risk is within the acceptable level by the management. It determines the compliance with risk appetite of the company. Achievement of acceptable risk indicates that residual risk is minimized and within control.
Detection Risk
Risk that the auditors fail to detect a material misstatement in the financial statements.
Control Risk
Risk that a misstatement could occur but may not be detected and corrected or prevented by the entity's internal control mechanism.
