Equalisation reserves: classes other than credit business: example

Transfers in

Transfers out

Reserve carried forward

Net transfer in or out

This is a worked example of an equalisation reserve for an insurer writing insurance falling into two business groups. Many of the figures are simplified, for example, the amount of the net earned premium (the proportion of net written premium attributable to risk borne in the financial year) will not normally be the same as the net written premium.

Transfers in

The first stage in calculating the movements in and out of an equalisation reserve at the end of a financial year (see GIM7210) is to quantify the level of transfers into the reserve, looking at each business group separately. The transfers in for each business group will be the set percentage of premiums written for that group. In this example the company writes only two types of business falling within the equalisation reserves business groups GIM7030): marine and aviation (C) and nuclear risks (D). Net written premiums for the year are £67m for marine and aviation and £120m for nuclear risks.

The calculation of transfers in will be made as follows:

Business Group Net written premiums Transfer in % Transfer into reserve
       
Marine and aviation £67m 6% £4m
Nuclear risks £120m 75% £90m
Total     £94m

Transfers out

The next step is to see if any transfers out of the reserve have been triggered as a result of poor claims performance in that financial year. Each business group is looked at separately at this stage in the computation.

Marine and aviation

Net earned premium £63m
   
95% of net earned premiums £60m
Net claims incurred £70m
Excess £10m

 

 

 

 

There is a potential transfer out equal to this excess (£10m), but this is subject to the business group maximum reserve level for that year. This is calculated as follows:

Average net written premium over last 5 years £15m
   
40% of average net written premium over last 5 years £6m

The transfer out is therefore £6m, the lesser of the potential transfer out (£10m) and the business group maximum (£6m) for that year.

Nuclear risks

A transfer out is due if claims exceed 25% of the net earned premium.

Net earned premium  £120m
   
25% net earned premiums  £30m
Net claims incurred £3m

There is no excess of claims over the set percentage of premiums this year, so no transfer out is due.

Total transfers out of the reserve on account of abnormal losses

Marine and aviation £6m
   
Nuclear risk Nil
Total £6m

Reserve carried forward

If the equalisation reserve brought forward at the start of the year is £80m, the movements in the equalisation reserve will look like this:

Reserve b/f £80m
   
Transfer in £94m
Transfer out due to abnormal losses £6m
Potential reserve c/f £168m

But this is subject to the aggregate of the maximum reserve levels for each business group.

The maximum reserve level for marine and aviation was calculated when transfers out were considered. There was no need to calculate a reserve maximum for nuclear risk business at that stage because there was no potential transfer out of the reserve for that business. It needs to be calculated now.

Business group maximum reserve level - nuclear risks:

Average net written premium over last 5 years £25m
   
600% of average net written premium over last 5 years £150m
Group reserve maximum, marine and aviation £6m
Group reserve maximum, nuclear risks £150m
Aggregate maximum reserve level £156m

The reserve carried forward of £168m exceeds the aggregate of the business group maximum levels £156m so an additional transfer out of £12m is required to reduce to the maximum reserve level. This transfer out is not allocated to any particular business group.

Net transfer in or out

The final step is to aggregate the transfers in and out for all business groups to find the net transfer in or out of the reserve.

Transfers in £94m
   
Transfer out due to abnormal losses (£6m)
Transfer out due to exceeding maximum reserve level (£12m)
Net transfer in of £76m

The reserve is carried forward as a single amount covering all business groups. It is not necessary to break down the balance of reserves brought forward into separate business groups. If it were possible, and say the reserve brought forward at the start of the year was made up of £1m from marine & aviation and £79m from nuclear risks, the transfer out for marine and aviation would not be limited to the £5m made up of £1m brought forward plus £4m transferred in. The balance of the reserve may be used even though its origin was nuclear risk business.
