## Detailed Description

Implied vol term structure at a given date in the future.

The given date will be the implied reference date.

**Note:**This term structure will remain linked to the original structure, i.e., any changes in the latter will be reflected in this structure as well.

**Warning**It doesn't make financial sense to have an asset-dependant implied Vol Term Structure. This class should be used with term structures that are time dependant only.
