| 291.139 | Familiarity and self-interest threats are created by using the same senior personnel on an assurance engagement over a long period of time. The significance of the threats will depend on factors such as: |
| • | How long the individual has been a member of the assurance team; |
| • | The role of the individual on the assurance team; |
| • | The structure of the firm; |
| • | The nature of the assurance engagement; |
| • | Whether the client's management team has changed; and |
| • | Whether the nature or complexity of the subject matter information has changed. |
The significance of the threats shall be evaluated and safeguards applied when necessary to eliminate the threats or reduce them to an acceptable level. Examples of such safeguards include:
| • | Rotating the senior personnel off the assurance team; |
| • | Having a registered auditor who was not a member of the assurance team review the work of the senior personnel; or |
| • | Regular independent internal or external quality reviews of the engagement. |
