Solvency II – introduction
Solvency II is a new regime which changes fundamentally the insurers (and reinsurers).The insurers have to operate risk-based and it has a lot of new regulations and standards. The Solvency II. comes into force at 01.01.2016.The actuaries are affected most of all the new reserving methodology and the new SCR, MCR calculation.

Solvency II.Reserving I.
Reserving methodology is based on the best estimate
assumptions plus additional risk margin.
The best estimate shall correspond to the probability-
weighted average of future cash-flows within the contract
boundary, taking account of the time value of money
(expected present value of future cash-flows), using the
relevant risk-free interest rate term structure.
Insurance mathematics III. lecture
Solvency II.Reserving II.
The risk margin shall be such as to ensure that the value of the technical provisions is equivalent to the amount that insurance and reinsurance undertakings would be expected to require in order to take over and meet the insurance and reinsurance obligations.
Contract boundary: contract shall be taking into consideration till the date when one of partners (insurer or insured) can quit from policy without any consequence. In non-life section the typical possibility to exiting from policy is 1 year, it means that usually we have to calculate premium till end of first policy year – but claims according to first policy year can be reported later.
Insurance mathematics III. lecture
Solvency II.Reserving III.
In non-life section we can calculate separately reserve for premium and claims. The ultimate reserve will be the sum of reserve for premium and reserve for claims.
The reserve for premium can be calculated with the next formula:
𝑃𝑟𝑒𝑚𝑅𝑒𝑠=𝑈𝑃𝑅 ∙ (1−𝑃𝑏𝐶𝑎𝑛𝑐 )−𝐶𝑙𝑃𝑎𝑦−𝐷𝐴𝐶−𝐶𝑙𝐻𝐶−𝑀𝑎𝑖𝑛𝐶
1+𝑑𝑖𝑠𝑐𝑜𝑢𝑛𝑡𝑟𝑎𝑡𝑒
Remark: if the product is profitable then the amount has negative sign.

whereUPR signs the Unearned Premium Reserve;
PbCanc signs the probability of cancellation;
ClPay signs the claim payment for claims which occurred before policy anniversary;
DAC signs the deferred acquisition costs;
ClHC signs the claims handling costs for claims which occurred before policy anniversary;
MainC signs the maintenance cost which are affected till policy anniversary.

Example:
Let the total portfolio is one policy with the next data:
Beginning date: 01.10.2014
Annual premium: 50.000 Ft
Probability of cancellation: 15% yearly
Expected loss ratio: 70%
Commission: 6%
Claims handling costs: 9% of claim (in homework 0)
Maintenance costs: 10% of premium (in homework 0)
Discount rate: 5%

Example (continued)
We are calculating the reserve for premium at 31.12.2014.

Reserve for claims
Actuaries have to estimate reported and not yet reported claims togetherplus claims handling cost in the future. It shall be applied the discount rate according to year of expected claim payment.If there is no differing information (e.g. changing of portfolio) we can use previous information for claims.

Solvency II.Reserving VIII.
One possible method is as follows:
OS reserve
1.step: Calculating the ratio of previous payments related to lagging time (year, quarter year, month).
2.step: Calculating the ratio of actual OS reserve according to occurring date (year, quarter year, month).
3.step: Calculating the real OS need based on result of earlier OS reserve (e.g. result is +10% ,then the real OS need is lower with 10%).
4.step: Estimating the payment of real OS need based on 1. and 2. step.
5.step: Discounting the result of 4. step with adequate discount factors.
Insurance mathematics III. lecture
Solvency II.Reserving IX.
Example:
We have 126.000.000 Ft OS reserve (according to Solvency I.) and we have to calculate Best Estimate.
1. step: we have data from past payments according to laggingas follows:
0. year 1.year 2.year 3.year
60% 30% 9% 1%
2. step: we have data about OS reserve occurring date as follows:
2011 2012 2013 2014
1.000.000 5.000.000 20.000.000 100.000.000
Insurance mathematics III. lecture
Solvency II.Reserving X.
3. step: Result of earlier OS reserve is +5%. It means the real OS need is as follows:
2011 2012 2013 20144761905 19047618 95238090
4. step: Payment estimation as follows according to earlier steps:

5. step: The discount rates are given as follows:

Then the reserve for OS reserve will be the next:
𝑅𝑒𝑠𝑂𝑆=942856201,05

1,05 ∙1,04 ∙1,03=113.280.621

IBNR
It can be calculated with classical methods (just one difference: we have to take into consideration the result of earlier IBNR) it shall be considered which part of IBNR when will be paid (according to estimation). At the end the discount factors shall be applied.

Solvency II.Difficulties I.
There are a lot of questions, difficulties related to Solvency II., because this is a total new regime and the technical specifications - which have to be applied - are not exactly clear in each case. I highlight just two points from these questions
1. Segmentation
In Solvency II. the target is making homogenous risk portfolio and for these groups using the specifications. In the other side (in non-life section) there is given the business lines which have to be applied. These two requirements would be controversy if one homogenous risk portfolio does not fit to the given business lines.

2. Claim inflation
There is not clear whether there is possible to consider claim inflation or not. And if the answer is yes then how should be calculated. (In EU there are countries in which has high inflation but other countries have no high inflation.)
