Sensitivity analysis for main assumptions Mexico [Table Text Block]
The assumptions with a greater relative weight and whose volatility could have a greater impact in determining the present value of the cash flows starting on the fifth year are the discount rate and the growth rate. The table below shows, in a simplified way, the relative variation by which the CGU recoverable amount would increase (or decrease) as a result of a reasonable variation (in basis points) of each of the key assumptions, considered in isolation as of December 31, 2025, where, in each case, their value in use would continue to exceed their book value:
