Generally the beneficiaries of social security institutions and insurance companies contribute currently some percentages of their monthly salary, so that they will be protected by the social security institutions and insurance companies against economic and social distress that would be caused by the absence or substantial reduction of income from work as a result of various contingencies such as sickness, maternity, employment injury, invalidity, old age, etc. This research project analyzes, interprets and forecasts in next three years the benefits paid by RSSB, using Holt's two-parameter linear exponential smoothing time series model.
