# Risk factor: [SCO60.73] to [SCO60.75]

The **Risk Factor** is used to identify [sensitivities](./sensitivities).
However, it is not used directly in the calculations.
Instead, the **[Underlying](./underlying)** (generated from the **Bucket** and the **Location** for delta and curvature, and from the **Bucket** alone for vega) 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.

For Crypto 2a delta and curvature, the **Crypto asset and exchange** (Underlying) refers to the distinct crypto asset [SCO60.73](https://www.bis.org/basel_framework/chapter/SCO/60.htm?inforce=20230101\&published=20191215#paragraph_SCO_60_20230101_60_73) and the corresponding exchange [SCO60.74](https://www.bis.org/basel_framework/chapter/SCO/60.htm?inforce=20230101\&published=20191215#paragraph_SCO_60_20230101_60_74).\
For Crypto 2a vega, the **Crypto asset** (Underlying) refers to the distinct crypto asset [SCO60.73](https://www.bis.org/basel_framework/chapter/SCO/60.htm?inforce=20230101\&published=20191215#paragraph_SCO_60_20230101_60_73) without any differentiation by the exchange [SCO60.75](https://www.bis.org/basel_framework/chapter/SCO/60.htm?inforce=20230101\&published=20191215#paragraph_SCO_60_20230101_60_75).

| 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             | “Crypto 2a”                                           |
| 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)                     |
| Underlying        |     | Delta/Curvature | The crypto asset and exchange                         |
| Underlying        |     | Vega            | The crypto asset                                      |

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