摘要：The sustainability factor is a tool for which the main goal is to contribute to the solvenc y of Social Security. In Spain, it has been articulated by a Sustainability factor, based on a life expectancy ratio, and a Pension Revaluation Index that replaces the Consumer Price Index for revaluation. However, as outlined in this article, the alternatives chosen are not exempt from uncertainty in their practical application nor are they the only possibilit y of action.
