Risk Glossary

Clear definitions for every risk management term you'll encounter — from inherent risk to risk universe.

A

Additive Scoring

A risk scoring method where the final score equals Likelihood + Impact. This method produces a narrower score range and treats likelihood and impact as equally important.

See also:Risk ScoreMultiplicative Scoring
C

Control Effectiveness

An assessment of how well existing controls reduce the inherent risk. Often rated on a scale from None (0% reduction) to Very Strong (80–90% reduction).

COSO ERM

The Enterprise Risk Management framework published by the Committee of Sponsoring Organizations of the Treadway Commission. It integrates ERM with strategy and performance, and is widely used in corporate governance.

I

Inherent Risk

The level of risk that exists before any controls or mitigating actions are applied. It represents the raw exposure of the organisation to a threat.

See also:Residual RiskRisk Appetite

Impact

The consequence or severity of a risk event if it occurs. Impact is typically assessed across financial, operational, reputational, legal, and safety dimensions.

See also:LikelihoodRisk Score

ISO 31000

The international standard for risk management published by the International Organization for Standardization. It provides principles, a framework, and a process for managing risk that can be applied to any organisation.

K

Key Risk Indicator (KRI)

A metric used to signal that the level of risk exposure is approaching or exceeding the organisation's risk appetite. KRIs provide early warning before losses occur.

See also:Risk AppetiteRisk Monitoring
L

Likelihood

The probability or frequency with which a risk event is expected to occur. In a 5-point scale, ratings range from Rare (unlikely within 10 years) to Almost Certain (expected within 12 months).

See also:ImpactRisk Score
M

Multiplicative Scoring

A risk scoring method where the final score equals Likelihood × Impact. This method amplifies high-likelihood, high-impact risks and is the most widely used approach.

R

Residual Risk

The remaining level of risk after controls and mitigating actions have been applied to inherent risk. Residual risk is what the organisation actually lives with.

See also:Inherent RiskControl Effectiveness

Risk Appetite

The amount and type of risk an organisation is willing to accept in pursuit of its objectives. Often expressed as a threshold or tolerance band rather than a single value.

See also:Risk ToleranceInherent Risk

Risk Tolerance

The acceptable variation in outcomes related to specific objectives. Risk tolerance is more granular than risk appetite and is often set at the operational level.

See also:Risk Appetite

Risk Score

A numerical value representing the overall level of a risk, calculated by combining likelihood and impact. Common methods include multiplicative (L × I), additive (L + I), and weighted scoring.

See also:LikelihoodImpactScoring Method

Risk Response

The strategy chosen to address a risk. Standard responses include: Accept (live with it), Mitigate (reduce it), Transfer (shift it via insurance or contract), Avoid (eliminate the activity), or Exploit (take advantage of it).

See also:Risk TreatmentRisk Appetite

Risk Treatment

The specific actions taken to address a risk, aligned with the chosen risk response. A treatment plan documents what will be done, by whom, and by when.

See also:Risk ResponseControl Effectiveness

Risk Register

A structured document or database that records identified risks, their scores, owners, response strategies, and treatment plans. The central artefact in any risk management programme.

See also:Risk OwnerRisk Response

Risk Owner

The individual or role accountable for monitoring and managing a specific risk. The risk owner is responsible for implementing treatment actions and reporting on risk status.

Risk Heatmap

A visual representation of risks plotted on a matrix by likelihood (y-axis) and impact (x-axis). Colour-coding (green, amber, red) indicates severity zones at a glance.

See also:LikelihoodImpactRisk Score

Risk Universe

The complete set of risks relevant to an organisation across all categories — strategic, financial, operational, legal, reputational, and environmental. The starting point for any comprehensive risk assessment programme.

T

Three Lines of Defence

A governance model dividing risk management responsibilities across: (1) operational management, (2) risk and compliance functions, and (3) internal audit. Each line provides independent assurance.
