| **Description** | The valuation impact of the upward scenario after deduction of delta risk position for curvature risk factors                             |
| **Reference**   | [\[MAR21.5\]](https://www.bis.org/basel_framework/chapter/MAR/21.htm?inforce=20230101\&published=20200327#paragraph_MAR_21_20230101_21_5) |
| **Formula**     | $\displaystyle -\sum_{i}\left \{ V_i\left ( x_k^{(RW^{(curvature)+})} \right ) -V_i(x_k)-RW_k^{(curvature)}\cdot s_{ik})\right \}$        |

The measure **CSR non-Sec Curvature CVR Up** can be replicated with these measures: **CSR non-Sec Curvature shock-up prices** minus **CSR non-Sec Curvature Delta Weighted Sensitivities**.
