Modeling of Pension Fund Using Garch: Case Study of SSNIT
Abstract
The introduction of the three-tier contribution scheme under the new pensions
Act has brought great reforms in the pensions industry. Currently a total of
18.5% of the contributors basicsalary is deducted for pensions and only 11.0%
goes to SSNIT , 2.5% goes to the management of the National Health Insurance
Scheme and the remaining 5.0% goes to the second-tier The challenging aspect
of the new Pension Act is that , although the contribution level of SSNIT is
reduced ,SSNIT is asked to provide monthly pensions for at least fifteen years
(additional three years) so far as a contributor lives and also provide forms of
invalidity. In view of this, the researcher used the GARCH model in fitting
a model for the fund size and predicted the funding level of the Trust, The
sustainability ratio of the fund which determines how much sustainable the
fund was within this period was also examined The predicted values showed
an upwards trend in the fund size and an increase in the sustainability ratio. It
was also observed that one major factor that affected the funding level of the
trust was indebtedness to the Controller and Accountant Generals Department.
It was the institution with the highest indebtedness percentage. The study
recommended much lucrative investment opportunities for the Trust to look
at, to increase its sustainability level and also measures to put in place to
increase its outflow especially its expenses on operations and administration
