by HHI. Retention ratio and ceded ratio are proxies to the contracts made with the reinsurance companies outside Egypt. (Adler, 1984, pp. 41-50) stated a procedure for assessing the FXE using a single factor to estimate the changeability of the company’s equity returns to exchange rates.
R_(i,t)=α+γ_i 〖XR〗_(j,t)+ε_i
Where R_(i,t) is the return on company i, over the period t. 〖XR〗_(j,t) is the change in exchange rate. The coefficient γ_i measures the company’s total exposure to foreign exchange rate.
After that, (Jorion, 1991, pp. 363–376) measured the exposure using two-factor model, which becomes the standard for controlling the exchange rate risk.
R_(i,t)=α+β_i R_(m,t)+ γ_i 〖XR〗_(j,t)+ε_i

26-46; Bartov E. B., 1994, pp. 1755-1785; Bartov E. B., 1996, pp. 105–123; Griffin, 2001, pp. 215–241) among others.
According to the population division, the variables will be used as follow: In the first part of the population “listed insurance companies”, we will use the R_(i,t) as the return on the stock i on the companies, R_(m,t) is the return on EGX30 market index and 〖XR〗_(j,t) is the change in the foreign exchange rate over time period t. Then we will calculate the coefficient (FXE) γ_i monthly (using daily data), quarterly, semiannually, and annually (using weekly data) from 2000 till 2016 In the second part of the population “ unlisted insurance companies”, we will use R_(i,t) as the return on equity for the companies i as there are not included in the stock market, R_(m,t) is return on equity for the insurance market (life or P&C insurance market) and 〖XR〗_(j,t) is the change in the foreign exchange rate over time period t. Then we will calculate the coefficient (FXE) γ_i annually according to the available data from 2000 until 2016.
Then we will use a model similar to (Aggarwal R., 2010, pp. 1619-1636) with some modifications to identify the most important and significant variables causing this exposure.
