| **Description** | The measure showing contributors to the IMCCavg calculation                                                                                 |
| **Reference**   | [\[MAR33.41\]](https://www.bis.org/basel_framework/chapter/MAR/33.htm?inforce=20230101\&published=20200327#paragraph_MAR_33_20230101_33_41) |

The measure helps to validate **IMCCavg** calculation and inspect actual contributors to spot potential data quality issues, such as spikes or missing values.

Note: the lookback horizon, for instance 60 days, can be changed to a shorter or longer observation window using **CA-Lookback** context value.
