Notes: Sumario: In this article we propose a lattice algorithm for pricing simple Ratchet equity-indexed annuities (EIAs) with early surrender risk and global minimum contract value when the asset value depends on the CIR++ stochastic interest rates. In addition we present an asymptotic expansion technique that permits us to obtain a first-order approximation formula for the price of simple Ratchet EIAs without early surrender risk and without a global minimum contract value. Numerical comparisons show the reliability of the proposed methods.Related records: En: North American actuarial journal. - Schaumburg : Society of Actuaries, 1997- = ISSN 1092-0277. - 02/09/2013 Tomo 17 Número 3 - 2013 , p. 229-252Materia / lugar / evento: Matemática del seguro Cálculo actuarial Métodos actuariales Riesgo actuarial Tarificación Otros autores: Gaudenzi, Marcellino
