Under the probability and magnitude test, which statement is most accurate?

• A. Materiality is defined solely by whether it would change an investor's decision.
• B. Materiality is assessed by the probability that the event will occur and its magnitude.
• C. Materiality focuses only on the size of the financial effect.
• D. Materiality is irrelevant to investor decisions.

Answer: (B)

Materiality under the probability and magnitude test rests on two factors: how likely the event is to occur and how large its financial impact would be. This approach recognizes that an issue can be material either because it is probable and sizable, or because a less likely event would have a large enough impact to matter to investors. The statement that materiality is assessed by the probability of the event and its magnitude best captures this combined assessment. Other views are incomplete: focusing only on whether it would change an investor’s decision ignores the quantitative thresholds, focusing only on size ignores the likelihood, and saying materiality is irrelevant to investor decisions contradicts its purpose in reporting.
