# Risk factor [MAR10.9]

The **Risk Factor** is used to identify [sensitivities](./sensitivities).
However, it is not used directly in the calculations, instead the **[Curve](./curve)** and the tenor fields are used.
This means that multiple **Risk Factor Names** may be used for the same risk-factor.

| Field                   | Key | Risk Measure | Description                                         |
| ----------------------- | --- | ------------ | --------------------------------------------------- |
| As-of Date              | Y   | All          | Timestamp (at close of business) for the data (T-1) |
| Risk Factor Name        | Y   | All          | A name for the risk-factor                          |
| Risk Class              | Y   | All          | “GIRR”                                              |
| Risk Measure            | Y   | All          | “Delta”, “Vega”, or “Curvature”                     |
| Sensitivity Tenor       |     | Delta        | The time to maturity of the traded instrument       |
| Option Maturity         |     | Vega         | The maturity of the option                          |
| Underlying Maturity     |     | Vega         | The residual maturity of the underlying             |
| Curve Name (Underlying) |     | All          | Name of the curve                                   |

For Curvature, there is only a single risk factor per bucket and the
**Curve Name** can be the currency/bucket.
