  Interview with Nicholas Kallis, FSA, MAAA   Ques 1: Why did you choose Actuarial Science as a career? Answer: I recall my last year of high school graduation, pondering and deliberating on what a suitable career would be. My mathematics teacher introduced me to the world of actuarial science by bringing some magazines and periodicals to read about this profession. My teacher that way planted the seed and from that point on, further research and meeting a successful practicing actuary solidified this goal and path for me to pursue. Ques 2: How is it like to work in USA and Cyprus. What will be the difference you observe in both insurance markets? Answer: I must say, always from my point of view, the differences are significant. At the same time one has to fairly and reasonably compare the two countries and respective markets. The USA of course is quite advanced, offers tremendous opportunity in terms of credentialing, continuous development, remuneration and other aspects, as

Difference between Diversified and Undiversified SCR

Difference between Diversified and Undiversified SCR – Solvency II

Before reading this article, kindly read the following 2 articles to make the most sense out of it:

Solvency II - Phase 1

Solvency II - Phase 2

- Solvency II SCR is a Value at Risk measure, it can be calculated via Standard formula as well as via Internal Model

- VaR is calculated for each component risk, then the diversified SCR is determined with reference to the correlation between each component. This is done by taking the sum over all risks of the square root of the product of their SCRs multiplied by the correlation coefficient

- Broadly speaking, suppose you are a group Insurer with 4 entities across the globe named A,B,C and D

 - All four of them have SCR has $100 each. Then at Group Level your SCR is definitely less than $400 because we have to allow for diversification via correlation matrices.

- Diversification occurs wherever the risks are not perfectly correlated. (Hedging would occur where they were negatively correlated.) In EIOPA's case they have defined a correlation matrix for each risk type.



- A numerical example might help, say a company writes only term insurance business and invests only in equity (with no default risk for simplicity). Let their market risk component of SCR, SCR_m, be $20m and their Life component of SCR, SCR_L, be $10m (which would have been calculated by the company). The correlation between these two risks is defined by EIOPA to be 0.25.

The basic SCR before diversification is $30m i.e. 20+10

The diversified SCR is calculated as the sum over all (both) risks as follows:

SCR = SQRT( Corr_m,m * SCR_m * SCR_m + Corr_m,L * SCR_m * SCR_L

+ Corr_L,m * SCR_L * SCR_m + Corr_L,L * SCR_L * SCR_L )

= SQRT( 1 * 20 * 20 + 0.25 * 20 * 10 + 0.25 * 10 * 20 + 1 * 10 * 10 )

= $24.5m

- So there is a diversification benefit of $5.5m as the diversified SCR is that much lower than the undiversified SCR.
