Estado
La metodología, la estructura y las definiciones de The Global Risks Index son un borrador de trabajo preparatorio (2026), difundido para examen y comentarios y no para su aplicación. Ningún valor aparece hasta que se publica una edición a partir de un corte de evidencia gobernado; los valores incluyen entonces intervalos, clases, fuentes y su vía de corrección. Los simuladores aplican los métodos publicados a las cifras que usted elija y nunca muestran un valor del NXS-GRX.
Lo que NXS-GRX no es
NXS-GRX es información de investigación y analítica de riesgos. No es una calificación crediticia ni ESG y no usa ninguna escala de calificación; no es un índice de referencia para instrumentos financieros, ni estadística oficial, ni una alerta de emergencia o clasificación oficial, ni asesoramiento. No debe usarse para evaluar a personas físicas. Las clases de riesgo son bandas en una escala publicada, nunca clasificaciones de países ni de personas.
