Detailed Description

Ultimate forward term structure.

Dutch regulatory term structure for pension funds with a parametrized extrapolation mechanism designed for discounting long dated liabilities.

Relevant documentation can be found on the Dutch Central Bank website:

FTK term structure documentation (Financieel toetsingskader): https://www.toezicht.dnb.nl/binaries/50-212329.pdf

UFR 2015 term structure documentation: https://www.toezicht.dnb.nl/binaries/50-234028.pdf

UFR 2019 term structure documentation: https://www.rijksoverheid.nl/documenten/kamerstukken/2019/06/11/advies-commissie-parameters

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 zero rates is tested by checking them against reference values obtained from the official source.
extrapolated forward is validated.
rates on the cut-off point are checked against those implied by the base curve.
inspectors are tested against the base curve.
incorrect input for cut-off point should raise an exception.
observability against changes in the underlying term structure and the additional components is checked.

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.
