Smodel is a software package designed primarily for calculating hedging sensitivities (Greeks) and risk neutral valuation, but can be used for other purposes as well. It values GMDB, GMIB, GMAB, GMLB (lifetime withdrawal benefit), GMWB (withdrawal benefit for limited term), and GMSB (guaranteed surrender benefits) attached to variable annuities and equity index annuities using Monte Carlo simulation.
Smodel is used by Applied Stochastic, LLC to provide services to clients. It is also available for licensing.
