In this paper we consider a variable annuity which provides guarantees at death and maturity financed through the application of a state-dependent fee structure, as defined first in Bae and Ko (2013) and extensively analysed in Bernard et al. (2014) and MacKay
et al. (2017). We propose a quite general valuation model for such guarantees, along the
lines of Bacinello et al. (2011). We then analyse numerically the interaction between fee
rates, death/maturity guarantees, fee thresholds and surrender penalties under alternative model assumptions and policy holder behaviours. This allows us to get also some
interesting insights into the model risk. Since the assumptions adopted in the numerical
analysis are not at all trivial, we resort to Monte Carlo and Least Squares Monte Carlo methods of LSMC valuation algorithm.
