| **Description**                      | Generic regulatory liquidity-adjusted ES measure                                                                                          |
| **Hierarchies required in the view** | [Risk Classes](./risk-classes), [Data Sets](./data-sets)                                                                                  |
| **Reference**                        | [\[MAR33.4\]](https://www.bis.org/basel_framework/chapter/MAR/33.htm?inforce=20230101\&published=20200327#paragraph_MAR_33_20230101_33_4) |
| **Formula**                          | $\displaystyle ES = \sqrt{\left(ES_T(P)\right)^2 + \sum_{j\geq 2}\left(ES_T(P,j)\sqrt{\frac{(LH_j - LH_{j-1})}{T}}\right)^2}$             |

This measure applies liquidity horizons adjustment to the [ES (Basic)](./es-basic-ima) measure.
This measure needs to be combined with \[Risk].\[Risk Classes] and \[Risk].\[Data Sets] to produce a business interpretable result.
