Figure 8.7: Price of the GMxB with cliqueting strikes using (a) the optimal
lapse rate (“avel”), (b) only the maximum lapse rate, and (c) only the min-
imum lapse rate. Curves (a) and (c) almost coincide. Curve (a) is slightly
above Curve (c) around the money. The minimum lapse rate is flat at 2%,
except for year 1 (0%) and year 2 (0.5%). The maximum lapse rate equals
the minimum lapse rate plus 15%. The minimum mortality rate increases lin-
early over [0, T ], from 0.5% to 1%. The maximum mortality rate ...
