Abstract
The article sums up the main characteristic features of the multifund pension security system based on the experience of countries, where the model has been adopted. This is an analysis of possible portfolios, available to the insured persons to select from, their differences and their functioning in the course of time. Recommendations are made how to adopt some specific features of multifunds in the Bulgarian system, in order to optimize it. Three countries from Latin American (Chile, Peru, Colombia), one from Central America (Mexico) and five from Central and Eastern Europe (Lithuania, Latvia, Estonia, Slovakia and Hungary) are studied. The paper points out the main features of the system in Armenia – the latest country, having introduced such type of security – since 1.01.2014.
