This paper aims to review and assessed protection afforded by the Social Security System and the Government Service Insurance System, two out of the three agencies tasked with administering social insurance in the country. Like social security systems in other countries, the GSIS and SSS provides income support to government/ private sector employees and their families in times of contingencies like death, old age, sickness, and disability arising from work, and are financed out of the contribution of members and their employers. The GSIS and SSS are both mandatory, publicly managed, benefitdefined social insurance schemes with funding coming from members and their employers and investment income from reserves. Government guarantees the solvency of both systems and the levels of benefits prescribed. The coverage of the SSS and GSIS combined (28% of the total number of employed persons and 22% of total population who are at least 65 years old) is lower than the social security systems of Thailand, Malaysia, Singapore, and South Korea but higher than that of Indonesia. However, the replacement rate (i.e., the value of the pension payment as a percentage of the earnings of members during their working life) is estimated to be about about 70% for the GSIS and 67% for the SSS in 2007, higher than those of Indonesia, Malaysia, Singapore and Thailand. The growth of contributions to the GSIS lagged behind that of benefits payments in 2000-2007. Thus, the ratio of contributions to benefit payments declined continuously from 2.1 in 2000 to 1.3 in 2007. On the other hand, total the contribution of members to the SSS exceeds total benefit payments by about 2% in 2007, lower than the corresponding figure for GSIS but is a marked improvement from the situation in 1994-1995 and in 1999-2004 when the SSS was operating in the red and when SSS's contribution-to-benefit ratios was less than unity. The turnaround in SSS's contribution-to-benefit ratio in 2005-2007 was due to the increase in the mandated contribution from 8.4% in 2002 to 9.4% in 2003 and 10.4% in 2007. However, the contribution rate required to maintain the system in steady state equilibrium (i.e., in balance over the next 40 years) is estimated to be about 20%, almost double the current level in 2007. The global economic downturn will tend to reduce the stream of ontributions to the social security system as a result of the increase in unemployment and the reduction in the level of earnings on which contributions are based. At the same time, there will be a temptation on the part of policy makers to use the pension funds to partially finance the fiscal stimulus package that has been drawn in response to the crisis. However, using the pension funds for the purpose of pump priming the domestic economy will likely not match the primary objective of the fund to protect old-age income of members. Even without the global financial crisis, reforms aimed at improving the financial viability of and corporate governance in both the GSIS and the SSS have already been started. Some gains have already been achieved in various areas of concern but sustained effort is still needed. The needed reforms have already been articulated by various experts (e.g., Holzmann et al. 2000, Navarro 2004, OECD 2009, Asher 2008) and includes: (i) the broadening of coverage and enhancement of compliance; (ii) greater emphasis on fiduciary responsibility of social security institutions and improve the management of their investment portfolio; and (iii) reduction in administrative cost; and (iv) institution of additional parametric measures to improve sustainability of the social security institutions and reduce the national government's contingent liability. Prospectively, there is a need to explore the feasibility of a non-contributory social pension for aged poor given the low coverage of the informal sector in the SSS. -- defined-benefit social insurance ; replacement rate ; required contribution rate
