## Assessment Instructions

<details>

<summary><strong>Intent</strong>: What is the purpose of this indicator?</summary>

Describe the ancillary activities engaged in by the entity. This information is used in combination with the Sector & Geography (RC3) and Reporting Year (EC4) descriptions to describe the entity’s reporting boundary.

</details>

<details>

<summary><strong>Input</strong>: How do I complete this indicator?</summary>

**Significant activities:** Select all significant activities engaged in by the entity, outside of its main activity. Insignificant activities typically make up less than 1% of the entity’s budget, resourcing or revenue, so excluding them from sustainability reporting still provides a complete picture to stakeholders.

**Activities in reporting boundaries:** Select all of the ancillary activities that are included within the boundary of sustainability reporting of the entity. This must be a sub-set (or all) of the activities listed in the previous section (in other words only select from the activities that were selected in the previous list).

### Terminology

**Ancillary activity**

> The activities engaged in by the entity that allow it to provide its core service but are not its main activity.

**Main activity**

> The activities engaged in by the entity that allow it to provide its core service but are not its main activity.

</details>

<details>

<summary><strong>Validation</strong>: What evidence is required?</summary>

No evidence required.

</details>
