du contrat, l\u2019application directe du principe d\u2019\u00e9quivalence ne permet g\u00e9n\u00e9ralement plus d\u2019en d\u00e9terminer les primes. Cette note d\u00e9taille la mani\u00e8re de mener \u00e0 bien les calculs actuariels en pareil cas, \u00e0 l\u2019aide de l\u2019\u00e9quation de Thiele et du th\u00e9or\u00e8me de Cantelli. La m\u00e9thode consiste \u00e0 associer au contrat consid\u00e9r\u00e9 un contrat fictif sans ce type de prestations, et d\u2019invoquer le principe d\u2019\u00e9quivalence. Dans certains cas, cette approche simple et \u00e9l\u00e9gante ne s\u2019applique malheureusement pas. Une solution efficace consiste alors \u00e0 recourir \u00e0 un sch\u00e9ma d\u2019Euler afin de r\u00e9soudre num\u00e9riquement l\u2019\u00e9quation de Thiele et d\u2019en d\u00e9duire les primes et les r\u00e9serves. Cette approche num\u00e9rique permet d\u2019ailleurs d\u2019obtenir les primes et les r\u00e9serves en fonction des prestations pr\u00e9vues dans le contrat, s\u2019av\u00e9rant souvent suffisantes pour les besoins de la pratique. Les techniques utilis\u00e9es dans cette note sont illustr\u00e9es \u00e0 l\u2019aide de plusieurs exemples. L\u2019annexe r\u00e9sume bri\u00e8vement les \u00e9l\u00e9ments principaux de th\u00e9orie actuarielle relatifs au probl\u00e8me consid\u00e9r\u00e9.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-0f29719 e-con-full e-flex e-con e-child\" data-id=\"0f29719\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;gradient&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-2952de9 elementor-widget__width-inherit elementor-widget elementor-widget-text-editor\" data-id=\"2952de9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><b>Sector: <\/b>Insurance<\/p><p><b><\/b><b>Expertise: <\/b>Life Insurance<\/p><p><b>Authors:<\/b> Gireg Willame,<\/p><p>Michel Denuit et<\/p><p>Julien Trufin<\/p><p><b>Publisher:<\/b> Detralytics<\/p><p><b>Date:<\/b> December 2017<\/p><p><b>Language:<\/b> French<\/p><p><b>Pages:<\/b> 44<\/p><p><b>Reference :<\/b> Detra Note 2017-2<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-c6ae38d e-flex e-con-boxed e-con e-parent\" data-id=\"c6ae38d\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-a1c05c2 elementor-widget elementor-widget-spacer\" data-id=\"a1c05c2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f183faa elementor-widget elementor-widget-heading\" data-id=\"f183faa\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">About the authors<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-53f26ef e-flex e-con-boxed e-con e-parent\" data-id=\"53f26ef\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-45ca7dd e-con-full e-flex e-con e-child\" data-id=\"45ca7dd\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-d43f55d elementor-widget elementor-widget-image\" data-id=\"d43f55d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"500\" height=\"500\" src=\"https:\/\/detralytics.com\/wp-content\/uploads\/2026\/06\/Gireg.png\" class=\"attachment-large size-large wp-image-7529\" alt=\"\" srcset=\"https:\/\/detralytics.com\/wp-content\/uploads\/2026\/06\/Gireg.png 500w, https:\/\/detralytics.com\/wp-content\/uploads\/2026\/06\/Gireg-12x12.png 12w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-f0de6fc e-con-full e-flex e-con e-child\" data-id=\"f0de6fc\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-224cb75 elementor-widget elementor-widget-heading\" data-id=\"224cb75\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Gireg Willame<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-58dff6d elementor-widget elementor-widget-text-editor\" data-id=\"58dff6d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Gireg is an Expert and Domain Lead Non-Life at Detralytics.
