問題文
A payroll bureau's board has agreed that it will accept no more than a stated level of exposure from automated processing. Its model risk standard also specifies that any model whose monthly error rate exceeds a stated figure must be withdrawn. An auditor is asked how these two statements relate. Which answer is correct?
選択肢
- The second overrides the first for operational purposes, because a measurable limit can be tested and a statement about willingness to carry exposure cannot, so only the measurable figure is worth testing against.
- The first expresses how much exposure the bureau is willing to carry overall, and the second is an operating limit derived from it for one measurable dimension of a single model.
- They are two expressions of the same thing, so satisfying the error rate limit for every model demonstrates that the board's stated level of exposure has been respected across the bureau.
- They have no relationship, since one is set by the board and the other by the risk function, and statements made at different levels of an organization address different subjects that should not be read together when assessing whether the bureau is operating within its limits.
