Role Assignment

Go up to Terms and Definitions

A Role Assignment associates an entity with a Role in a specified context.

A Role defines a function, capacity, or position that may be performed or held. A Role Assignment identifies the entity that performs or holds that Role in a particular activity, transaction, contract, agreement, process, situation, or regulatory context.

The entity may be a Party or another entity permitted by the applicable model. When a Party performs a Role, the Role Assignment provides the relationship through which the Party participates in the specified context.

A Role Assignment may identify:

• The entity performing or holding the Role
• The assigned Role
• The context in which the Role applies
• The effective period of the assignment
• The authority or basis for the assignment
• A represented Party, when the entity acts on behalf of another Party
• The status of the assignment
• Applicable constraints
• Evidence supporting the assignment
• Provenance describing how the assignment was established

The Role Assignment is distinct from the entity, the Role, and the context. A change to a Role Assignment does not change the identity of the entity or the definition of the Role.

The permanent source record should be maintained in the applicable public References annex when a reference identifier is assigned.

• A Role Assignment is distinct from the Role being assigned
• A Role Assignment is distinct from the entity performing or holding the Role
• An entity may have multiple Role Assignments
• The same Role may be assigned to multiple entities when the applicable context permits
• Assignments of the same Role in different contexts are separate Role Assignments
• A Role Assignment may be limited to a specified effective period
• A Role Assignment does not, by itself, establish that the entity is authorized, qualified, or eligible to perform the Role
• When an entity acts on behalf of another Party, the performing entity and the represented Party are recorded separately
• Ending a Role Assignment does not remove the entity, redefine the Role, or erase the historical assignment
• Evidence and provenance may be retained to explain how the assignment was established, changed, or terminated

Example Bank participates in an FX Trade as a counterparty.

The applicable Role Assignment identifies:

• Example Bank as the Party performing the Role
• Counterparty as the Role
• The FX Trade as the context
• The period during which the assignment applies

If Example Bank is also responsible for regulatory reporting, that responsibility is represented by a separate Role Assignment identifying Reporting Counterparty as the Role and the applicable reporting context.
