The need to meet financial obligations arising from the claims requires the determination of the optimum deposited claims reserve with banks. Therefore, the present research study aimed at finding the loss ratio (incurred losses to premium) and determining the optimum portfolio of risky and risk-free assets of insurance companies during ۱۹۹۶-۲۰۱۷ by conducting a case study on Iran Insurance Company. Based on the relevant data, the highest loss ratio of ۸۱ percent belonged to ۱۹۹۸-۹۹, and the lowest percentage of ۶۲ percent belonged to ۲۰۰۳-۲۰۰۴. Konno Mean-Absolute Deviation Portfolio Optimization Model was utilized to determine the optimum portfolio of Iran Insurance Company.
