Abstract

In this paper, we analyze the latest guarantee feature in the variable annuities market: guaranteed minimum withdrawal benefits for life (GMWB for life) which are also called guaranteed lifelong withdrawal benefits (GLWB). This option gives the client the right to deduct a certain amount annually from the policy’s account value until death—even if a unit-linked account value drops to zero. We show how such products can be analyzed within a general framework presented in Bauer et al. (ASTIN Bull. 38(2):621–651, 2008). We price the embedded guarantee for different product designs and parameters under both, deterministic and optimal client behavior.

Fußnoten
1
Since G W is not needed for GLWB options, two processes G E and one process G W are sufficient.
 
2
Contracts where the step-up is applied based on the account value before withdrawals can be considered by letting \(G_{t}^{E +} = \max\{ G_{t}^{E-} ;x_{W} \cdot A_{t}^{ -} \}\).
 
3
Note that surrender charges only apply to the exceeding part. Therefore surrender charges were not considered in case (c) above.
 
4
Whenever a non-guaranteed withdrawal occurs, future guarantees are also reduced. We here describe a so-called pro-rata reduction which is the predominant form in the market.
 
5
Here, IR + denotes the non negative real numbers (including zero); furthermore we let \(\mathit{IR}_{ +}^{\infty} = \mathit{IR}_{ +} \cup\{ \infty\}\).
 
6
We understand rational in the sense of maximizing the economic value of a contract. Thus, rationality is defined independent of any utility functions.
 
7
For an introduction to Monte Carlo methods see, e.g., Glasserman (2003).
