Detailed Description

Implied 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.

Tests:

• the correctness of the returned values is tested by checking them against numerical calculations.
• observability against changes in the underlying term structure is checked.
