The National Social Security Administration (; mostly known for its acronym ANSES) is a decentralized Argentine Government social insurance agency managed under the aegis of the Ministry of Health and Social Development. The agency is the principal administrator of social security and other social benefits in Argentina, including family and childhood subsidies, and unemployment insurance. Overview The majority of Argentina's public social programs, aside from those related to health and housing, are administered by ANSES. Around 95% of Argentine senior citizens (5.7 million) receive ANSES pensions, whose amount is adjusted semi-annually. Argentines in the labor force earning less than 5,200 pesos (us$350) monthly, are entitled to benefits upon marriage; pregnancy, birth, or adoption of a child; for maternity leave or prenatal care; and for a disability in a child or spouse, as well as to a modest unemployment insurance benefit for up to 6 months. The most important poverty relief program administered by the ANSES is the Asignación Universal por Hijo (Universal Childhood Entitlement). The benefit, 340 pesos (us$70) a month per child, is assigned to 3.6 million children under age 18 (30% of the nation's total), and includes the deposit of 20% of the check in a savings account accessible only upon certification of the child's vaccination and enrollment in school. The program was budgeted at around us$2.5 billion for 2011 (6% of the total). Other recent programs include Conectar Igualdad, which envisaged the purchase of 3 million netbooks for secondary school students and teachers; and PRO.CRE.AR, a subsidized mortgage initiative for moderate income borrowers largely shut out of the nation's tight credit market. The ANSES is funded by an 11% withholding tax rate and payroll taxes (56%), as well as by a share of value added and other tax receipts (22%), contributions from the national budget (17%), and interest receipts (4%). Expenses include social security payments (63%), transfers to provincial and other pension funds (20%), family assistance (12%), and the netbook program (2%); administrative expenses were around 2%. The agency maintains a stabilization fund, the Sustainability Guarantee Fund (FGS), which held approximately us$46 billion in a variety of financial instruments as of December 2011, of which 58% was held in government securities, 14% in productive investment, 12% in time deposits, and 9% in the Buenos Aires Stock Exchange. The ANSES issues a Código Único de Identificación Laboral (Labor Identification Code) to all registered workers covered under the Public
