Bear in mind that the risk margin (RM) is only the cost of holding part of the SCR.
Let's think first about the purpose of the RM. The BEL allows for market risk through use of risk-free rates for investment returns and discounting. However, it does not allow for other types of risk, hence an adjustment has to be made: the addition of the RM.
There are many different ways in which a market-consistent liability can be adjusted to allow for non-market risks. For example, the non-market assumptions (mortality, expenses etc) can have margins included. EIOPA chose instead to use what we call the 'cost of capital' method, which means determining the cost of holding capital to support those non-market risks. This is just one way by which an approximate allowance can be made for the non-market risks within the liability cashflows.
So, when we are thinking about holding provisions, the total amount that we should hold is the BEL + RM: a market-consistent liability which allows for both market and non-market risks, and which thus represents the amount that another insurer would require in order to take on the liability.
Now let's think about calculating an embedded value. This means determining the value of the business to the shareholder. The RM and SCR will both be locked into the business: the shareholder cannot receive them immediately. Therefore it can be argued that the assets backing the RM and SCR have less than market value worth to the shareholder - particularly if there are frictional costs which will erode their value (eg taxation, investment expenses) during the time that they are locked in. As Lynn says above, for a non-market-consistent EV, the erosion of value comes from the fact that the assets will earn an assumed investment return which is lower than the discount rate (or the shareholders' required rate of return). The deduction made to the market value to allow for the lock-in value erosion is the 'cost of capital' adjustment. It reduces the embedded value (the value of the business to the shareholder).
So the 'cost of capital' in each of these cases represents a slightly different thing. In the Solvency II balance sheet, it (the RM) represents an allowance for non-market risks. In the EV, it represents the erosion of value from having capital locked into the company without being able to distribute it to shareholders immediately.
However, there is a relationship. If a company decided that it would define its EV 'cost of capital' as being the RM, then (ignoring with-profits business, which makes things more complicated):
EV = free surplus + required capital (SCR + RM) - cost of holding capital (RM)
= free surplus + SCR = own funds.
This is as explained in Chapter 19 of the notes, and is consistent with the concept of technical provisions as being the amount that another insurer would require to take on the liabilities.
Hi Lindsay
Thanks a lot for helping me understand the RM. I have found my understanding about Risk Margin under SII, lets denote it as RM(SII), has been quite different. And i just this last round of discussions around it. Below is the plot:
1.As you mentioned, RM(SII) is the prudence for non-hedgable risk calculated as frictional cost of holding SCR capital for these risk using 'Cost of Capital' approach. that means: RM(SII) =Prudendnce for non-hedgable risk(NHR) = frictional cost ot SCR.
My understanding was, RM(SII) is Prudence for NHR + Cost ot holding SCR for NHR risks.
Basis for my such understanding is based on the content of two pages of Chapter 19, as given below:
page 18, section MCEV, content under 'Component of an MCEV' :
These are
1.free surplus(princ 4)
2.required capital(SCR?, if based on SII, as per prinp 5)
2(a) minus "Frictional cost of required capital"
3. ViF:
3(a) PVFP
3(b) minus Time value of option and guarantee
3(c) minus cost of residual non-hedgeable risks-RM(EEV), when using MCEV.
You must see 2(a) and 3(c) are separate things.
Page 20, EV reporting under SII:
Points written as
(i) if there is no PVIF(assuming item 3(c) above is taken as 2(b) and release of RM(SII) is clubbed with release of SCR)
(ii) company considering RM(SII) to be appropriate measure of cost of residual NHR, RM(EEV), and lock in cost of holding regulatory capital(SCR)
The EV equals to SII own funds.
Hope you can see the reason of my confusion. Can you help me on this?
