# ProRataLeafLevel

|                 |                                                           |

| **Description** | Select a level for bottom-up Pro-Rata Capital Allocations |
| **Variations**  | [pro\_rata](./pro_rata)                                   |

This context value enables bottom-up calculation for a Pro-rata measure. Please note that **ProRataHierarchy** context value must be set to "NONE".

The capital charge is calculated at the leaf level, then pro-rata coefficients are computed so that the scaled leaf-level charges sum to the charge at the **ReferenceLevel**.

Scaled Leaf-level charges are additive and can be rolled up to any level.
