### Additional Margin

|                          |                                                             |
| ------------------------ | ----------------------------------------------------------- |
| **Description**          | Contribution of the Additional Margin into the Total Margin |
| **Required hierarchies** | [PortfolioID](../dimensions/portfolioid#portfolioid)        |

**Formula**

$Additional IM = AddOnFixed + AddOnNotional + AddOnSIMM$

### AddOn Fixed

|                 |                                        |
| --------------- | -------------------------------------- |
| **Description** | Fixed portion of the Additional Margin |
| **Notation**    | $AddOnFixed$                           |

**Formula**

$AddOnFixed = Param_AddOnFixedAmount$

### AddOn Notional

|                 |                                                                    |
| --------------- | ------------------------------------------------------------------ |
| **Description** | Portion of the Additional Margin defined as percentage of notional |
| **Notation**    | $AddOnNotional$                                                    |

**Formula**

$AddOnNotional = \sum_{p \in products} Param\ AddOnNotionalFactor_p \cdot Notional_p$

### AddOn Notional Factor

|                 |                                                                                    |
| --------------- | ---------------------------------------------------------------------------------- |
| **Description** | Notional Multiplier parameter for a given regulation and netting set (PortfolioID) |

### AddOn SIMM

|                 |                                                                                    |
| --------------- | ---------------------------------------------------------------------------------- |
| **Description** | Portion of the Additional Margin defined as percentage of sensitivity-based margin |
| **Notation**    | $AddOnSIMM$                                                                        |

**Formula**

$AddOnSIMM = \sum_{pc \in product\ classes} Param\ ProductClassMultiplier_pc \cdot SIMM_{pc}$

### Product Class Multiplier

|                 |                                                                                         |
| --------------- | --------------------------------------------------------------------------------------- |
