# 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)**, **Curve Type**, and tenor fields are used (as appropriate for the risk-measure).
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          | “CSR non-Sec”                                         |
| Risk Measure            | Y   | All          | “Delta”, “Vega”, or “Curvature”                       |
| Sensitivity Tenor       |     | Delta        | The time to maturity of the traded instrument (Delta) |
| Option Maturity         |     | Vega         | The maturity of the option (Vega)                     |
| Curve Name (Underlying) |     | All          | Name of the relevant issuer credit spread curve       |
| Curve Type              |     | Delta & Vega | “Bond” or “CDS” (Delta and Vega)                      |

For Curvature, the risk-factor is the same as the underlying.
