1. Executive summary
Our objective is to build two models that price two types of reinsurance and evaluate the results.
The reinsurance contracts analyzed are for a book of business in General Liability. We will look at
Quota Share and Excess of Loss reinsurance contracts and take into consideration, profit,
commissions, and different layers for the Excess of Loss reinsurance.
2. Introduction
Reinsurance is the practice of insurers transferring portions of risk portfolios to other parties by
some form of agreement in order to reduce the likelihood of having to pay a large obligation
resulting from an insurance claim. By getting a reinsurance contract, the insurance company
reduces the risks associated with underwritten policies, it can also spread the risks across
alternative institutions.
In our project we are taking the position of a Reinsurance company. The line of business that we
are studying is General Liability which covers claims of bodily injury, physical injury, property
damage, and advertising injury. It is sold to protect the businesses against incidents that may occur
on the premises or at other locations where they conduct business.
A Quota Share reinsurance is a proportional contract where one or more reinsurance companies
take a stated percentage share of each policy that an insurer issues. The reinsurer will then receive
a fixed percentage of the premiums and will pay the stated percentage of claims. In addition the
reinsurer will allow a ceding commission to the insurer to cover the cost incurred by the insurer for
acquisition and administration.

An Excess of Loss reinsurance is a non-proportional reinsurance in the sense that it will only pay
out if the total claims suffered by the insurer in a given period exceed a stated amount, which is
called “retention” or “priority”. We analyze it on a per occurrence basis and consider two different
contract layers: 3 million excess of 2 million and 4 million excess of 1 million. In the following
figure we can see that the premium ceded to the reinsurance company is an amount set at the
beginning of the contract.

Following we will describe the pricing methodologies for a Quota Share and an Excess of Loss
reinsurance.
3. Quota share
To price a Quota Share insurance we need to first take into consideration the historical loss ratios
projected to the treaty period. The loss ratio is the ratio of expected ultimate losses and the
adjusted historical premium. The expected ultimate losses is calculated using a Chain Ladder and
the Bornhuetter-Ferguson method (B-F method) and the adjusted historical premium needs to be
on leveled and trended using the parallelogram method. Then comes the decision that the ceding
company takes in terms of the percentage of losses retained and the type and amount of ceding
commission. The ceding commissions studied in this project are:
● Flat commission
● Sliding scale
● Profit commission
● Loss corridor commission.
For the purpose of comparing the different models of reinsurance in this project we will use the
Flat ceding commission.
The ceding commission will be set by the insurance company, but as reinsurers we need to
estimate a ceding commission that will consider the expected loss cost, expenses, brokerage fees
and the profit that we are willing to get for this contract.
Before committing to take the risk, the insurance company and the reinsurance company compare
the expected loss ratios that each of them calculated based on the historical gross losses and they
agree on the terms of the ceding commission.
For this model we had the following information available:
● A triangle of General Liability ground up losses with 15 years of experience.
● Earned premium.
● Historical Rate changes.
We have the following assumptions:
● Premium trending rate is 2%.
● Loss trending rate is 4%.
● No more loss development after 15 years.
● Interest rate do not change.
A more detailed explanation of the calculations follows.

3.1 Loss development.
The first step of pricing a Quota Share reinsurance is to obtain the ultimate losses by accident year.
In order to do this, we use the Chain Ladder method and the Bornhuetter-Ferguson method (B-F
method).
3.1.1. Chain ladder method
This method operates under the assumption that patterns in claims activities in the past will
continue to be seen in the future. The ground up losses in the triangle represent the incremental
losses settled in the development year (column) for the given accident year (row).
a) Age-to-age factor
The age-to-age factor measures the changes of the development from one year to the next. It is
calculated by taking the ratio of reported loss of chosen year to the previous year. For each of the
age-to-age factors, we calculated different ways to obtain an average. We calculated the following
average types:
● Geometric average:
𝐺𝑒𝑜𝑚𝑒𝑡𝑟𝑖𝑐 𝑎𝑣𝑒𝑟𝑎𝑔𝑒 = ∏ 𝑥𝑖
● Median average:
𝑀𝑒𝑑𝑖𝑎 𝑎𝑣𝑒𝑟𝑎𝑔𝑒 = ∑ 𝑥𝑖
𝑛−2
𝑖=1
− min(𝑥𝑖) − max(𝑥𝑖)
● Volume weighted average:
𝑉𝑜𝑙𝑢𝑚𝑒 𝑤𝑒𝑖𝑔ℎ𝑡𝑒𝑑 𝑎𝑣𝑒𝑟𝑎𝑔𝑒 =
𝛴(𝐿𝑜𝑠𝑠𝑒𝑠 𝑎𝑡 𝑛 + 12, 𝑜𝑓 𝑡ℎ𝑒 𝑙𝑎𝑠𝑡 5 𝑦𝑒𝑎𝑟𝑠)
𝛴(𝐿𝑜𝑠𝑠𝑒𝑠 𝑎𝑡 𝑛, 𝑜𝑓 𝑡ℎ𝑒 𝑙𝑎𝑠𝑡 5 𝑦𝑒𝑎𝑟𝑠)
● Simple average:
𝑆𝑖𝑚𝑝𝑙𝑒 𝑎𝑣𝑒𝑟𝑎𝑔𝑒 =
∑ 𝑥
𝑛
We did not observe a significant variation in the prior methods of obtaining the average of the
development factors. So, we decided to use the simple average as is is easier to interpret. We
assumed that we won’t have loss development after 15 years then the tail age-to-age factor is 1.
We observed that even though we were working with cumulative ground up losses there were
some development years that had loss development factors less than one. This can happen due to
the fact that the data includes some salvage and subrogation. This behavior was mostly present in
older years and at more than 48 months of development. We decided to include them in the
selected simple average to reflect this behavior.
8
Figure 3.1
b) Estimating Ultimate loss amounts
The cumulative development factors (CDF) are used to measure changes of loss for each policy
from certain accident year to ultimate loss. The Chain Ladder method calculates them for each
accident year as the multiplication of the Loss development factors after the last period that the
data was observed. The quantity further used in this analysis is the percentage of loss reported that
is obtained as 1/CDF.
Figure 3.2
3.1.2. Bornhuetter-Ferguson method (B-F method)
The B-F method is used to calculate expected ultimate loss. Compared to the Chain Ladder
method, B-F method it can avoid overreaction when unusual values appear. It is based on reported
loss and the projected to ultimate loss calculated by the Chain Ladder method. As mentiones
above,
𝑈𝑛𝑟𝑒𝑝𝑜𝑟𝑡𝑒𝑑 𝐿𝑜𝑠𝑠 = 𝑃𝑟𝑜𝑗𝑒𝑐𝑡𝑒𝑑 𝑡𝑜 𝑈𝑙𝑡𝑖𝑚𝑎𝑡𝑒 𝐿𝑜𝑠𝑠 ∗ (1 −
1
𝐶𝐷𝐹
)
Then the expected ultimate loss is the sum of reported loss and unreported loss.
9
3.1.3. Trending
After obtaining the Ultimate losses per accident year we need to trend them. We assumed a loss
trend of 4% per year. So we measured the length of trend from the average date in the
corresponding accident year to the the average current date 07/01/2016. The adjusted ultimate loss
is calculated as follows:
𝐴𝑑𝑗𝑢𝑠𝑡𝑒𝑑 𝑈𝑙𝑡𝑖𝑚𝑎𝑡𝑒 𝐿𝑜𝑠𝑠 = 𝐸𝑥𝑝𝑒𝑐𝑡𝑒𝑑 𝑈𝑙𝑡𝑖𝑚𝑎𝑡𝑒 𝐿𝑜𝑠𝑠 ∗ (1 + .04)𝑙𝑒𝑛𝑔𝑡ℎ
3.2 Premium development
Steps
3.2.1 On-level premium
The parallelogram method assumes that premiums are written evenly throughout the time period, it
involves adjusting the aggregated historical premium by an average factor to put the premium on-
level. We need to consider historical rate changes when we on-level the premiums. We had the
following historical rate changes per year:
Year
Rate
Change
2006 -3.0%
2007 -4.0%
2008 -5.0%
2009 -4.0%
2010 2.0%
2011 2.0%
2012 -0.5%
2013 -2.0%
2014 1.0%
2015 -1.0%
Figure 3.3
The objective of the parallelogram method is to replace the average rate level for a given historical
year with the current rate level. The steps for the parallelogram method are as follows:
1. Determine the timing and amount of the rate changes during the experience period.
2. Calculate the portion of the year’s earned premium corresponding to each rate level group.
3. Calculate the cumulative rate level index for each rate level group.
4. Calculate the weighted average cumulative rate level for each year.
5. Calculate the on-level factor as the ratio of the current cumulative rate level level index and the
average cumulative rate level index for the appropriate year.
6. Apply the on-level factor to the earned premium for the appropriate year.
To view the rate changes in a graphical format as in figure 3.4 assume that rate changes only
impact policies written on or after the effective date therefore the rate change are represented by a
10
diagonal line, the slope of the line depends on the term of the policy for the purpose of this
analysis they are one year policies.
Figure 3.4
The on level factor formula is as follows:
𝑂𝑛 − 𝑙𝑒𝑣𝑒𝑙 𝐹𝑎𝑐𝑡𝑜𝑟 =
𝐶𝑢𝑟𝑟𝑒𝑛𝑡 𝐶𝑢𝑚𝑢𝑙𝑎𝑡𝑖𝑣𝑒 𝑅𝑎𝑡𝑒 𝐿𝑒𝑣𝑒𝑙 𝐼𝑛𝑑𝑒𝑥
𝐴𝑣𝑒𝑟𝑎𝑔𝑒 𝑅𝑎𝑡𝑒 𝐿𝑒𝑣𝑒𝑙 𝑖𝑛𝑑𝑒𝑥 𝑓𝑜𝑟 ℎ𝑖𝑠𝑡𝑜𝑟𝑖𝑐𝑎𝑙 𝑃𝑒𝑟𝑖𝑜𝑑
The numerator considers the most recent cumulative rate level index from Step 3. The denominator
is the result of Step 4.
3.2.2. Premium trending
We selected a one-step trending approach. The premium trend that we selected is 2%. The selected
trend factor is used to adjust the historical premium to the expected levels. The trend period is
typically measured as the length of time from the average date of policies with premium earned
during the historical period to the average written date for policies that will be in effect during the
time the rates will be in effect in this case 07/01/2016.
The trending factor is defined as follows:
𝑇𝑟𝑒𝑛𝑑𝑖𝑛𝑔 𝑓𝑎𝑐𝑡𝑜𝑟 = (1 + .02) 𝐿𝑒𝑛𝑔𝑡ℎ 𝑜𝑓 𝑡𝑟𝑒𝑛𝑑
Each on-level premium is then multiplied by the trending factor to get the adjusted ultimate
premium. The following is a summary table for the premium calculation.
11
Figure 3.5
3.3 Loss Ratio
After getting the adjusted ultimate loss and the on-leveled and trended premium for each accident
year, we get the loss ratio as follows:
𝐿𝑜𝑠𝑠 𝑟𝑎𝑡𝑖𝑜 =
𝐴𝑑𝑗𝑢𝑠𝑡𝑒𝑑 𝑈𝑙𝑡𝑖𝑚𝑎𝑡𝑒 𝐿𝑜𝑠𝑠
𝐴𝑑𝑗𝑢𝑠𝑡𝑒𝑑 𝑈𝑙𝑡𝑖𝑚𝑎𝑡𝑒 𝑃𝑟𝑒𝑚𝑖𝑢𝑚
We select the expected loss ratio as the average loss ratio of the 15 years of experience. This gives
is a 54% Loss ratio.
12
Figure 3.6
3.4 Loss Ratio Distribution fitting
Based on all the analysis above, now we have 15 years of historical loss ratios. As an exercise we
wanted to get more information about the distribution of the loss ratio of this book of business.
With the information available we have 15 years of experience.

AY
Loss
Ratio
2001 61.9%
2002 54.9%
2003 53.3%
2004 45.4%
2005 52.8%
2006 29.0%
2007 60.5%
2008 59.1%
2009 43.9%
2010 54.5%
2011 40.8%
2012 58.6%
2013 64.8%
2014 63.9%
2015 66.7%
Figure 3.7
We use @risk software to fit a distribution to the loss ratio. Then based on the Akaike information
criterion (AIC) criteria we compared the distributions and choose the one that had the lowest AIC
criterion.
Note: The Akaike information criterion (AIC) is a measure of the relative quality of statistical
models for a given set of data. Given a collection of models for the data, AIC estimates the quality
of each model, relative to each of the other models. Hence, AIC provides a means for model
selection.
The selected distribution is a Weibull distribution. Figure 3.8, shows it.
14
Figure 3.8
We found that the Weibull distribution is the best distribution to describe our 15 years historical
loss ratio data. But the problem for this distribution is that this distribution has a light tail, which is
not good enough to predict some extreme events. The reason behind this may be that our historical
data size is not large enough, so we need to add one more extreme event in our dataset. We added
one observation of 125% loss ratio to the 15 observations previously used.
After adding this new observation we fitted the new distribution again and using the sale AIC
criteria, we found that the Log-Logistic distribution is a good fit.
Figure 3.9
The second best distribution is a Pearson5 Distribution. The Log-Logistic distribution has similar
shape to the log-normal distribution but has heavier tails. In this analysis we can see that the
Pearson5 distribution has a heavier tail than the Log-Logistic distribution. Even though that is the
15
case we would recommend the use of the Log-Logistic because its cumulative distribution can be
written in closed form and it is known for it uses in economics and to measure survival analysis.
We found this analysis very interesting and we got motivated to further investigate about the
sensitivity of the pricing methods to the loss ratio and how this distribution can be used in
replacing or complementing the Increased Limit Factors from the industry used in the Excess of
Loss pricing analysis.
3.5 Treaty Features
An important part of pricing a Quota Share reinsurance is to take into consideration the ceding
commission. For our final analysis we used a Flat ceding commission but we also studied different
types. Following are the description and examples of the commissions that can be considered in
this type of reinsurance.
3.5.1. Sliding Scale Commission
When there are disagreements between insurer and reinsurer, we may need to use the sliding scale
commission to keep a balance between the insurer and reinsurer.
Sliding scale commission ensures that the actual rate payable is directly related to the loss ratio,
which means more commission in good years and lower commission in bad years.
A common adjustable feature is the “sliding scale” commission. A sliding scale commission is a
percent of premium paid by the reinsurer to the ceding company which “slides” with the actual
loss experience, subject to set minimum and maximum amounts.
We made 1,000 loss ratio simulations. In the calculation of the sliding scale commision, for each
loss ratio simulated, we need to determine in which range the loss ratio falls into: below 50%, 50%
- 60%, or above 60%. And then we apply the sliding scale to these loss ratio, and calculate the new
average value of the 1,000 data, which is considered as the expected sliding commission.
Figure 3.10
16
3.5.2.Profit commission
A profit commission subtracts the actual loss ratio, ceding commission and a “margin” for
expenses from the treaty premium and returns a percent of this as additional commission.
Profit commission is the reward given to the insurance company for providing profitable business,
by the reinsurer.
Here is the formula:
Profit = Premium – Loss - Commission-Reinsurer’s margin
Profit Commission is payable in addition to ceding commission and applicable to proportional
treaties and rarely seen in Non Proportional treaties.
Figure 3.11
3.5.3.Loss Corridor
The Insurance company will reassume a portion of the reinsurer's liability if the loss ratio exceeds
a certain amount.
A loss corridor provides that the ceding company will reassume a portion of the reinsurer’s
liability if the loss ratio exceeds a certain amount.
In our case the corridor is 25% of the Loss ratio layer from 65% to 75%.
Figure 3.12
17
3.5.4 Flat ceding commission
For the purpose of our project we will price a Quota Share insurance assuming a 25% of ceded
losses. Meaning that the insurance company will retain 75% of the losses.
For the purpose of the analysis we calculated a flat ceding commission taking into the following
paraments:
● Expected loss ratio: 54%
● Brokerage fee: 2%
● Profit: 10%
The calculation of the Flat ceding commision is as follows:
𝐶𝑒𝑑𝑖𝑛𝑔 𝐶𝑜𝑚𝑚𝑖𝑠𝑖𝑜𝑛 = 1 − 𝑃𝑟𝑜𝑓𝑖𝑡 − 𝐸𝑥𝑝𝑒𝑛𝑠𝑒 − 𝐵𝑟𝑜𝑘𝑒𝑟𝑎𝑔𝑒 𝐹𝑒𝑒 − 𝐸𝑥𝑝𝑒𝑐𝑡𝑒𝑑 𝑙𝑜𝑠𝑠 𝑐𝑜𝑠𝑡
Considering these parameters we obtained a Flat ceding commission of 29%.
Expected
Loss Cost
$ 6,786,592
Brokerage
Fee
$251,350
Expenses $628,376
Ceding
Commission
$3,644,447
Profit $1,256,752

4. Excess of Loss.
4.1. Pricing methods of Excess of Loss reinsurance.
Exposure and experience rating are the most prevalent approaches to pricing excess of loss
reinsurance contracts. They are frequently used together in a form of a credibility-weighted
average to calculate the expected loss cost.
18
As mentioned before we consider two different layers for an Excess of Loss reinsurance:
•3 x 2 Three million excess of two million.
•4 x 1 Four million excess of one million.
The assumptions used for both Experience and Exposure methods are:
•Exposure trend for Premiums 2%.
•Historical rate changes.
•Loss trend 4%.
•A tail factor 10% to the Loss Development Factor on each layer.
4.1.1. Experience rating
The basic idea of experience rating is that the historical experience, adjusted properly, is the best
predictor of future expectations. Experience rating uses historical losses of the ceding company. As
we will be able to see in the case of the two layers studied in the project, there could be the case
that no losses will fall in the layer and this will make the calculations of the expected loss cost less
reliable.
The information used in this analysis is on a per claim basis. The premium used was the one used
in the Quota Share pricing, on leveled and trended. Below are the calculation’s steps.
1. Individual loss claims. Each of the ground up losses is trended to the future average date of loss in
this case is 7/1/2016. The resulting loss is applied to the reinsurance layer.
2. For each claim calculate the loss corresponding to the layer to price and aggregate them by
accident year.
3. Aggregated losses in the layer are then developed to ultimate.
4. Historical premium is adjusted for rate changes to the prospective premium level.
5. The loss cost of the layer by year is calculated by dividing the ultimate trended losses in the layer
by the corresponding adjusted premium.
6. Then we calculate the average of the loss cost between the most recent years, 2006 to 2016.
7. The reinsurance rate is developed by loading the loss cost for the reinsurer’s expense and profit.
In our analysis we can see that for the layer of 3 x 2 there are some years that do not have any
losses falling in this layer. Whereas for the layer 4 x 2 all the accident years considered, from 2006
to 2015 have losses. Figure 4.1 shows the resulting Loss cost per layer.
19
Layer Experience
Loss cost
3 x 2 5.62%
4 x 1 17.96%
Figure 4.1
It seems that in the layer of 4x1 presents more losses in the layer than the 3 x 2 Excess of Loss
reinsurance. In this case, we could say that is for this particular layer the Experience method is
more “reliable”.
In the appendix we show a summary table for both layers.
4.1.2. Exposure rating
The exposure rating method relies on a current snapshot of the policies subject to the reinsurance
contract. This snapshot will include some measure of the percentage of premium exposing the
reinsurance contract, usually called the “Limit profile”, and an estimate of the gross loss, before
reinsurance, for such policies. To perform an exposure rating we require a severity distribution,
from which we can get the Increased Limit Factors (ILFs). We obtained these ILFs based on the
industry benchmark provided by our mentor. The objective of the exposure rating method is to
estimate the proportion of the loss for the underlying policy that is expected in the Excess of Loss
layer.
Exposure rating is suitable for those companies who have a book of business similar to the
industry’s, for companies lacking data or having not reliable data. In this case, exposure rating
might be the best way to obtain the expected loss cost since experience rating may not be very
reliable. In this method all is based on in-force data without relying on historical one.
The ILFs are defined as:
𝐼𝐿𝐹 =
𝐸𝑥𝑝𝑒𝑐𝑡𝑒𝑑 𝐶𝑜𝑠𝑡 𝑎𝑡 𝑡ℎ𝑒 𝑑𝑒𝑠𝑖𝑟𝑒𝑑 𝑝𝑜𝑙𝑖𝑐𝑦 𝑙𝑖𝑚𝑖𝑡
𝐸𝑥𝑝𝑒𝑐𝑡𝑒𝑑 𝐶𝑜𝑠𝑡 𝑎𝑡 𝑡ℎ𝑒 𝐵𝑎𝑠𝑖𝑐 𝐿𝑖𝑚𝑖𝑡
The Loss ratio is defined as the gross loss divided by the gross premium. The loss cost can be
calculated using the loss ratio as in the following formula:
𝐿𝑜𝑠𝑠 𝑐𝑜𝑠𝑡 =
𝐺𝑟𝑜𝑠𝑠 𝐿𝑜𝑠𝑠
𝐺𝑟𝑜𝑠𝑠 𝑃𝑟𝑒𝑚𝑖𝑢𝑚
×
𝐶𝑒𝑑𝑒𝑑 𝐿𝑜𝑠𝑠
𝐺𝑟𝑜𝑠𝑠 𝑃𝑟𝑒𝑚𝑖𝑢𝑚
20
One way of calculating the loss cost is first calculate the Base premium that is the premium of the
basic limit. We use the inforce premium by policy limit. The Base premium is calculated as
follows:
𝐵𝑎𝑠𝑒 𝑝𝑟𝑒𝑚𝑖𝑢𝑚 =
𝑃𝑟𝑒𝑚𝑖𝑢𝑚 𝑜𝑓 𝑐𝑒𝑟𝑡𝑎𝑖𝑛 𝑝𝑜𝑙𝑖𝑐𝑦 𝑙𝑖𝑚𝑖𝑡
𝐼𝐿𝐹 𝑜𝑓 𝑡ℎ𝑒 𝑝𝑜𝑙𝑖𝑐𝑦 𝑙𝑖𝑚𝑖𝑡
Then to get the premium corresponding to the losses in the layer of interest, we multiply the Base
premium by the difference of the upper and lower limit’s ILFs.
𝐴𝑑𝑗𝑢𝑠𝑡𝑒𝑑 𝑝𝑟𝑒𝑚𝑖𝑢𝑚 𝑜𝑓 𝑙𝑎𝑦𝑒𝑟 = (𝐵𝑎𝑠𝑒 𝑝𝑟𝑒𝑚𝑖𝑢𝑚) ∗ (𝑈𝑝𝑝𝑒𝑟 𝑙𝑖𝑚𝑖𝑡 𝐼𝐿𝐹 − 𝐿𝑜𝑤𝑒𝑟 𝑙𝑖𝑚𝑖𝑡 𝐼𝐿𝐹)
We then multiply the adjusted premium of the layer to the expected loss ratio. To obtain the
expected losses in the layer per policy limit.
Part of the Exposure analysis is to take into consideration the ceding company’s limit profile. We
obtain this by dividing each policy limit in force premium by the total inforce premium. Once we
have the limit profile we multiply each of the expected losses by limit in the layer times its
corresponding limit profile and then we add them all to obtain the expected loss cost.
The expected loss cost for the layer 4x1 is 1.66% and for the layer 3x2 is 0.65%.
Figure 4.2
21
4.2. Expected Loss cost.
After calculating the experience and exposure loss cost we combine them in a form of credibility
giving both methods the same weight.
Figure 4.3
5. Conclusion
Based on the analysis on the Quota Share and the Excess of Loss pricing , now we can give a final
review and comparison for these two different reinsurance contracts.
As part of the reinsurance contract our company will receive part of the premium from the ceding
company and then we will take part of the risk involved. The main difference of these two types of
reinsurance contracts is how to determine the part of the risk assumed.
Here is a graph to show this concept:
Figure 5.1
Assuming the percentage ceded in the case of the Quota Share and the limits in the case of the
Excess of loss, we can discuss the final outcome for these two methods:
22
Figure 5.2
In summary, we have described the methods to price a Quota Share and an Excess of Loss
reinsurance. We described the assumptions we made and how given a set percentage of profit we
came up with a given ceded premium. For pricing purposes this is just a reference for the
reinsurance company. In a real life scenario, the insurance company and the market will dictate the
terms of the contract. This is when the different types of ceding commissions come into play as a
tool for the reinsurance company to negotiate with the ceding company if their calculations of
expected losses differ. There are many metrics to determine whether to write a treaty: loss ratio,
dollars of profit, ceded premium, cost of capital, ROI to name a few. In this case we base our
recommendations on profit.
We assume 10% of profit for each contract. As we can see in Figure 5.2 the expected loss for the
Quota Share is just 30% above the one expected for the 4x1 Excess of Loss reinsurance, and the
profit is 87% higher that the 4x1 Excess of Loss contract. For this reason we come to the
conclusion that recommending a Quota Share reinsurance is a reasonable start in the negotiations.
For the two layers of the Excess of Loss reinsurance. We found that the layer of 3x2 had years
where no data was available when calculation the Experience rating and the expected loss cost
calculated may not be very reliable due to the lack of data. For this reason in the case that the
insurance company may be interested in an Excess of Loss reinsurance we will recommend to
quote a 4x1 layer. In general there are many factors that determine which kind of reinsurance the
ceding company selects. For example, It can depend on the resources to write business to ensure
profitability or how much surplus relief it needs.

Abstract
Reinsurance is the practice of insurers transferring portions of risk portfolios to other parties by some
form of agreement in order to reduce the likelihood of having to pay a large obligation resulting from an
insurance claim. The intent of reinsurance is for an insurance company to reduce the risks associated with
underwritten policies by spreading risks across alternative institutions.
In our project we are taking the position of a Reinsurance company. We are going to analyze a General
Liability insurance. A General Liability insurance covers claims of bodily injury, physical injury,
property damage, and advertising injury. It is sold to protect the businesses against incidents that may
occur on the premises or at other locations where they conduct business.
26
Our objective is to come up with the best reinsurance structure for this book of business. We will
look at
Quota Share and Excess of Loss reinsurance contracts. We will take in to consideration, profit,
commissions, and different layers for the Excess of Loss reinsurance. We plan to include sensitivity
analysis as well as a detail list of all the assumptions needed to come up with the recommended rates per
type of contact.
Our project will include the following phases:
1. Data analysis: In this phase we will work on performing an exploratory analysis of the data,
understand its structure and come up with the assumptions needed. During this phase we are also going to
study the claim development methodologies as well as on leveling of premiums and trending both
premiums and losses. The objective of this phase is to come up with and Ultimate loss and an estimated
loss ratio.
2. Loss cost analysis: In this phase we plan to use the loss ratio of the prior phase and we are going
to perform an Exposure and an Experience rating analysis. We will also add some simulations all this with
the objective of obtaining the most “accurate” projected loss cost.
3. Pricing analysis: Use the projected loss cost to calculate for example for the Quota Share
reinsurance the ceding commission to get this book of business profitable. We will analyze different limit
scenarios for the Excess of Loss reinsurance. We will consider the possibility of adding treaty features and
perform a sensitivity analysis with the objective of giving a profitable rate for our reinsurance company.
Initial Project Milestones and Deliverables
We are meeting with our mentor on a weekly basis. Prior to each meeting we will prepare a meeting agenda.
We are currently in Phase 1 of our project. Our mentor has given us a list to literature to read related to
pricing reinsurance contracts. We are in the process of getting data. Our mentor kindly has offered to provide
us a dataset that most likely will include Loss experience, premium, expenses, of individual claims and
some policy listings. In the meantime, we are reviewing the recommended literature and we plan to discuss
any issues or exercises that will help us to get a better understanding of the theoretical procedures of the
project.
27
Followed by each or our weekly meeting we will prepare the weekly deliverables. These include agenda,
meeting minutes and a video update.
The key deliverables for the project include a statement of intent (week 3), a project charter (week 4), a
midterm presentation (week 7), a final report (week 12), and a final presentation (week 12).
28
Proposed Learning Outcomes
Analytical Skills
With the help of our mentor we are looking forward to understanding the assumptions needed to come
up with a model as close as possible to a real life one. To do this we will need to understand our data
and its structure. Also for the pricing phase we will need to understand what factors are needed to be
modified in order to give a sensitivity analysis and finally come up with a profitable reinsurance rate.
Technical Knowledge
With the guidance of our mentor and by performing extensive research in this topic, we will integrate
different tools from statistics, mathematics, and reinsurance theory. For example in the Data analysis
phase we can use R to come up with descriptive statistics. We are also planning to use @Risk to fit a
distribution to the expected losses data. We will use Excel to consolidate our analysis and have a user
friendly interphase to perform the sensitivity analysis.
Business Skills
Working on this project as a team we believe that will help us develop our business skills. For example
we need to coordinate efforts to come up with all the weekly deliverables. We rotate and divide work
so we all collaborate in a balance way and we help each ot her understand the project’s objectives a
theory behind it. We will practice our presentation skills by preparing our weekly video update and by
presenting our work progress to our mentor and project supervisors.
29
Oral Communication and Writing Skills
On a weekly basis we prepare an agenda, and the require deliverables for our project. We also need to
communicate in a professional way with our mentor and supervisors. We are planning on presenting
our project in the most professional manner. Our intention is to give pricing advice in the most
comprehensive way possible as we were talking to our insurance clients.

Abstract
Reinsurance is the practice of insurers transferring portions of risk portfolios to other parties by some form
32
of agreement in order to reduce the likelihood of having to pay a large obligation resulting from an
insurance claim. The intent of reinsurance is for an insurance company to reduce the risks associated with
underwritten policies by spreading risks across alternative institutions.
In our project we are taking the position of a Reinsurance company. We are going to analyze a General
Liability insurance. A General Liability insurance covers claims of bodily injury, physical injury, property
damage, and advertising injury. It is sold to protect the businesses against incidents that may occur on the
premises or at other locations where they conduct business.
We will work on a pricing analysis for a Quota Share and an Excess of Loss reinsurance contracts with the
objective to maximize the profit margins based on this book of business. A Quota Share reinsurance is a
proportional contract where one or more reinsurers take a stated percentage share of each policy that an
insurer issues. The reinsurer will then receive a fixed percentage of the premiums and will pay the stated
33
percentage of claims. In addition the reinsurer will allow a ceding commission to the insurer to cover the
cost
incurred by the insurer for acquisition and
administration.
An Excess of Loss reinsurance is a non-proportional reinsurance in the sense that it will only pay out if
the total claims suffered by the insurer in a given period exceed a stated amount, which is called
“retention” or “priority”. We are going to analyze it on a per risk basis.
Scope and Objectives
Our objective is to come up with the best reinsurance structure for this book of business. We will look at
Quota Share and Excess of Loss reinsurance contracts. We will take in to consideration, profit,
commissions, and different layers for the Excess of Loss reinsurance. We plan to include sensitivity
analysis as well as a detail list of all the assumptions needed to come up with the recommended rates per
type of contact.
Our project will include the following phases:
1. Data analysis: In this phase we will work on performing an exploratory analysis of the data,
understand its structure and come up with the assumptions needed. During this phase we are also going
to study the claim development methodologies as well as on leveling of premiums and trending both
premiums and losses. The objective of this phase is to come up with and Ultimate loss and an estimated
loss ratio.
2. Loss cost analysis: In this phase we plan to use the loss ratio of the prior phase and we are going
to perform an Exposure and an Experience rating analysis .We will also add some simulations all this
with the objective of obtaining the most “accurate” projected loss cost.
3. Pricing analysis: Use the projected loss cost to calculate for example for the Quota Share
reinsurance the ceding commission to get this book of business profitable. We will analyze different limit
scenarios for the Excess of Loss reinsurance. We will consider the possibility of adding treaty features
and perform a sensitivity analysis with the objective of giving a profitable rate for our reinsurance
company.
Approach and Threshold for Project Success
34
We got the following data for a GL line of business: A triangle of the Ground up reported losses and
LAE as of 12/31/2015. For years 2001 to 2015 and experience of 15 years;
We have GL individual Losses for claims that exceeded a $500,000 limit; and we also have available
premium listings based on different GL limits.
Some of the techniques that we are planning to implement are:
In the loss ratio calculation we are going to determine the projected ultimate losses by using the
ground up losses triangle and the Bornhuetter -Ferguson (B-F) Technique.
For reinsurance pricing we will perform an Exposure rating technique using an Increase Limit
Factors (ILF) method, and an Experience rating technique.
35
We will fit a curve to the expected loss ratio for a Quota Share and to the selected loss cost for the
XL. We may use @Risk and R to fit and select the most appropriate loss distribution that will describe
them.
We will simulate the loss ratio and the selected loss cost to help us come up with suggested margins
on negotiations while we consider treaty features.
Assumptions and Constraints
We will base our calculations on an Accident Year basis. For this we will consider the date of loss field in
the data set.
Although we will identify the assumptions once we start a more detailed analysis of the data. We consider
that we will need to define them for the following steps on the project:
Trends.
Ceding commissions.
Expenses.
On-leveling the premium.
Adjustments for historical rate changes.
Determine the reinsurance treaty features.
Decide if we are going to base our analysis on the most recent data or t he whole history.
We may encounter some constraints in the simulation and curve fitting process since we lack a large
amount of exposure years.
Initial Project Milestones and Deliverables
We are meeting with our mentor on a weekly basis. Prior to each meeting we will prepare a meeting
36
agenda. We are currently in Phase 1 of our project. Our mentor has given us a list to literature to read
related to pricing reinsurance contracts. We got the data, that our mentor kindly provided. We continue
reviewing the recommended literature and we plan to discuss any issues or exercises that will help us to
get a better understanding of the theoretical procedures of the project. We will start with a Loss
development analysis using the B-F method.
Followed by each or our weekly meeting we will prepare the weekly deliverables. These include agenda,
meeting minutes and a video update.
37
The key deliverables for the project include a statement of intent (week 3), a project charter (week 4), a
midterm presentation (week 7), a final report (week 12), and a final presentation (week 12).

• Agenda for first weekly meeting
• Project Plan
3. Progress Report
We met in person in the Science and Engineering Library. In this first meeting our Mentor
introduced some basic concepts about P&C reinsurance and we discussed the possible
projects. After a discussion, we decided that our project will focus on an analysis of two
types of reinsurance and we plan to build a pricing model from the reinsurance perspective
that will evaluate a XL reinsurance and Quota Share reinsurance for the General Liability
line of business. Some useful reading material is also given by our mentor for next following
weeks.
42
4. Meeting Details
4.1 Explanation of Concepts In Reinsurance
Our mentor explained two different types of reinsurance: Quota share reinsurance and
excess loss reinsurance. For a general liability business, we are planning on considering
a pricing model that will take in to consideration different structures that will be useful
in negotiations with the insurance companies.
4.2 General Idea of Project
Due to different characters shown in liability, such as loss ratio, we can set up a model
and decide which type of reinsurance we should apply. To develop this, we need to
look at historical record of book of business, determine what type of reinsurance
structure we want to play with and project forward to get the fully developed loss,
seeing how it goes under different type of reinsurance. Development triangle is require
to realize this process. After collection and development of date, we can get a fitting
distribution and their statistical character such as volatility, correlation and tail to
decide whether it is a profitable scenario by simulation using software. Our project’s
name could be “General liability reinsurance model”.
4.3 Supplement Comment
 There are some features for quota share and excess of loss which are interesting.
For quota share, ceding commission which is the fee reinsurance company need
to pay to insurance for written expense need to be consider carefully cause
there are always credit can be applied when disagreement happen. For excess of
loss, there is a feature called risk statements, which is the cap of loss.
 Risk attaching and loss occurring are two types of trending, one is related date
when policies are written and the other one is related to when loss occurs.
 There are two ways based on casualty pricing, one is based on experience
which depend on annual book of business, the other on is based on exposure
which is about individual risk.
4.4 Material Recommendation
 Basic of reinsurance pricing is a very good article which introduce ways to price
for property and casualty separately.
 Presentation in CAS Website
43
4.3 Question:
Citlalli Blanchet: What kind of data we need to get different scenario?
Mentor: In terms of quota share reinsurance, we only need annual premium, expense
and other general data from book of business but in terms of excess
Jiawen Wu: Do we need to test our model?
Mentor: I don’t think we need to worry that part. We can just assume the data are
correct. I rather you focus on concept and modeling building.
5. Date and Time of the Next Meeting
The students and mentors will meet on conference call on Tuesdays.

We had Skype call with mentor for further discussion about our project outline. During
meeting, Mr Kapadia sketched the whole project would be and all steps we are going to
take, which gave us an outline for the whole process. After this, he talked about certain
details in terms of our enquiry, which cleared our confusion on the material given last
week.
45
4. Meeting Details
4.1 Description of Data
Mentor would give us the data with premium, loss, expense and individual claims
which we can analysis individual basis for loss policy, exposure rating, policy limits
something like that. In terms of data, it will be consistent that premium, loss and large
losses all go together.
4.2 Sketch for Whole Project
For quota share, we only do experience analysis but for excess of loss, we do both
experience rating and exposure rating. Firstly, given rate changes, we do group-up
experience anaylsis for projected loss ratio. With alternative loss ratio, we do
experience analysis and exposure analysis and look at different tricky options. After
that, we use simulation, determine distribution and compare different structure.
In terms of quota share, based on projected loss ratio and alternative loss ratio, we can
decide the ceding commission and some adjustment for that. In terms of excess of loss,
for different layer, we calculate exposure loss cost and compare it with experience loss
cost. Based on these two loss cost, we can fit distributions based on them and compare
their statistics feature. After comparison, we can make decision on it.
4.3 Supplement Comment
 Assumption is important for this project. We need to list all the assumptions to
from chain ladder to why we switch from experience analysis to exposure
analysis.
 Sensitivity test is needed to see how the number changes when assumption
twisted.
46
4.3 Question:
Jiawen Wu: Catastrophe for local enterprise will have huge impact but for
international will be small. So which type are we going to have?
Mentor: We only consider general liability. So the catastrophe impact will be
minimum since they only affect property which is third-party coverage.
Citlalli Blanchet: How do we know whether the exposure analysis or experience
analysis to choose?
Mentor: We need to look at the assumptions. For experience analysis, the company
should be stable, which means no much changes within a long period. For those
companies who raised their policy limits, shifted their area, exposure analysis would be
more suitable.
Zijun Chen: Could you explain more about exposure rating?
Mentor: Exposure rating only depends on in-force exposure. Loss costs are only
calculated by increasing factor, which is nothing to do with historical loss as well.

5. Date and Time of the Next Meeting
The students and mentors will have a conference call on Thursday morning.

week. Next week we are going to have mid-term presentation.
49
4. Meeting Details
4.1 Advice for Mid-Term Presentation Draft
Mr Kapadia suggested us to change our title as reinsurance pricing rather than pricing
quota share and excess of loss reinsurance to avoid too much unnecessary details. he
thought we should give the conception of reinsurance at the beginning rather than in
front of quota share pricing methodology. He give us an example outline for our
presentation: conception of quota share and excess of loss, objective of pricing,
factors we taking into consideration, project basis, summary to show result for quota
share then the methodology used. In terms of excess of loss, we don’t need to go into
details since we haven’t touched yet.
4.2 Correction of Ceding Commission calculation
4.2.1 Sliding Scale
Frist of all, Jiawen explained how we got the ceding commission by sliding scale
commission, profit commission and loss corridor respectively. Then Mr Kapadia
give his option for each method. For sliding scale commission, we only use one
sliding between the commission we want to pay as a reinsurer (minimum) and the
fee the reinsured want to receive (maximum). We decide to use 30%-40% as bound.
For sliding rate, 1:1 is assumed. We don’t need to consider ultimate profit at first but
sliding is needed at the beginning. For convenience, we need to use have 1000
simulation for loss ratio and ceding commission calculated by each method so that
we can see the changes of ceding commission when loss ratio distribution changed.
We don’t need to consider expense and brokerage for sliding scale commission. We
can use middle point of bounds to check our result because the final expected ceding
commission should be nearly there.
4.2.2 Profit Commission
In terms of profit commission, brokerage which is the agency fee for broker between
reinsurance company and insurance company (for quota share, we assume 2% and for
excess of loss, we assume 10%) and margin (we can chose between 10%-15%) is
needed which is the expense for reinsurance company. The ceding commission
reinsurance company want to pay, loss ratio distribution, flat commission and margin
should be decided at the beginning. After we decide the percent return, the final
commission is the sum of flat commission and percent return. Low ceding
commission can be chosen as 30%. If the actual profit is negative, not profit returned
needed. 50% percent return is suggested.
50
4.3 Loss Corridor
Our loss corridor is fine so we don’t need to change it.
5. Date and Time of the Next Meeting
Mr Kapadia might come for mid-term presentation next week on Wednesday.

We had a call conference with mentor for fifth discussion about our project. During
meeting, Mr. Kapadia sketched the whole triangle calculation method and some
detailed knowledge about the trend in the calculation, which gave us an outline for the
whole triangle loss calculation. After this, he talked about some concept about the
experience pricing and exposure rating, which cleared our confusion on the material
given last week.
52
4. Meeting Details
4.1 Review of the project charter
In the last week, we have uploaded our project charter and sent it to Mr.Kapadia. After
reviewing the whole project charter, he gives us some feedbacks, which indicating that
there are some minor mistakes and he will send an email about the suggestion of the
project charter in the next week.
4.2 Explanation for the triangle calculation
For quota share, we only do experience analysis but for excess of loss, we do both
experience rating and exposure rating. Firstly, given rate changes, we do group-up
experience analysis for projected loss ratio. With alternative loss ratio, we do
experience analysis and exposure analysis and look at different tricky options. After
that, we use simulation, determine distribution and compare different structure.
When we calculate the loss ratio, we need to use the triangle method. Here are some
steps for this method:
Step1–Compile claims data in a development triangle
Step2–Calculate age-to-age factors
Step3–Calculate averages of the age-to-age factors
Step4–Select claim development factors Step5–
Select tail factor
Step6–Calculate cumulative claim development factors
Step7–Project ultimate claims
4.3 Supplement Comment
• Assumption is important for this calculation. We need to look at the industrial statistics
and assume some inflation rate for our calculation.
53
4.3 Question:
Zijun Chen: There are some age-to-age factors smaller than 1. When we take the
average of these factors, how to deal with those values?
Mentor: We take average of all the values. If the final outcome is larger than 1, we just
keep it, otherwise, we use 1.
Zijun Chen: When we do the triangle calculation, the loss ratio is too large, it seems
something goes wrong.
Mentor: When we check the excel file, there is a mistake in the vba code. After fixing
the code, this problem should be solved.
Zijun Chen: The trends used on premium and loss haven't been decided.
Mentor: We assume the loss trend is 4% , and we need to adjust the project loss.s

5. Date and Time of the Next Meeting
The students and mentors will have a conference call or in-person meeting on next
Thursday.

3. Progress Report
We discussed the comments that Mr. Kapadia had on the Project Charter. We talk
about the approach that we were going take in our midterm presentation. We also talk
about some modifications that we need to add the gross loss triangle calculations.
Finally, we discuss the simulation process and the use of the @Risk software.
56
4. Meeting Details
4.1 Comments on Project Charter
We currently have the project in three phases: 1.- Data analysis 2.- Loss cost analysis.
3.-Pricing analysis.
Mr, Kapadia suggested to have the phases more like 1.-Data analysis and projecting
Ground up losses. 2.- Pricing of Excess of Loss and Quota Share reinsurance. 3.-.
Final decisions and over all summary result analysis.
We agreed that we will decide on the best split of the phases in the future but this
could be the approach that we should be taking.
4.2 Midterm presentation discussion.
The midterm presentation is due in two weeks, we talk about the approach that we
should take and what topics should we mention in more detail.
Mr. Kapadia suggested presenting an overview of the project by giving an introduction
to reinsurance, explaining what General Liability is and defining the types of
reinsurance that we are planning to price. Then give definitions and examples of
Excess of Loss and Quota share insurance and comment on the assumptions. Since for
the Quota Share reinsurance we have already been working the Gross Loss triangle we
can explain a little more in detail our results and calculations. Then we can give an
introduction to the treaty features that we are applying and their definitions. For the
Excess of loss insurance we can give an introduction of the pricing plan and talk about
the data available for this analysis. We can also show a list of assumptions that we so
far have used and the one we will need to consider. In general to give a non to technical
presentation of our project but that at the same time will give a clear overview of our
progress and our objectives.
4.3 Discussion on Gross Loss Triangle calculations.
We suggested to add different averages and methods of obtaining the Loss
Development Factors because in our data we have some years with salvage and
subrogation. We agreed to add these calculations and discuss our finding in our next
meeting.
4.4 Discussion on Simulation on Loss Ratios.
57
We agreed that the software @Risk is our best option to work with simulations and
tests of distributions that best fit our data.
We agreed that we all are going to come up with some data analysis and discuss our
finding in our next meeting. We all need to get more familiarized to @Risk. We all
are very interested in learning how to use it since is a software that is commonly
used in the reinsurance industry.
We discussed options on how to come out with our results. Like what happens if we
add some catastrophic losses. Try different approaches in terms of tests and
simulations.
4.5 Discussion about commissions.
We discussed how to add a sliding scale commission. And then how to get our profit
and what can be a reasonable profit commission all based on the simulations of the
Loss Ratios. And we want to calculate the expected value of this commission.
We also wanted to discuss reasonable profit limits.
Mr. Kapadia suggested to add a table with the expected losses and the different
commission that we will consider.

3. Progress Report
We had in person meeting with mentor for further discussion about our exposure
rating. During meeting, Mr. Kapadia explain how we get loss ratio for each layer
for exposure rating using ILFs. After this, he talked about how we are going to
make final decision between quota share and excess of loss. He also suggested us
an outline for final presentation.
59
4. Meeting Details
4.1 Description of Data
We have details about information of individual policy from ceding company,
including policy limit, premium, effective date and etc., which affect loss of
reinsurance company directly. ILFs are also given for each layer’s base premium.
4.2 Sketch for Whole Project
In order to get loss ratio for 4M/1M and 3M/2M reinsurance policy, we need to
calculate adjusted premium for each layer separately. We can get base premium
by dividing ILFs from premium and multiple the difference between upper limits
and lower limits, which is decide by both layer and policy limit, we get premium
for each layer. We assume each layer has loss ratio 55%. By applying this loss
ratio, we get expected loss for each layer. Percentage of premium compared with
totally premium multiple corresponding expected ratio is the total expected loss
for each layer. We sum them up then we get the ultimate loss for 4M/1M and
3M/2M layer individually.
Since we have loss ratio from both exposure rating and experience rating, we
weigh two values and come up a credible loss ratio for excess of loss based of in-
force policy and historical policy. In order to compare quota, share and excess of
loss, we need to consider qualitatively as well beside volatility, profit margin and
other consideration. We are going to have a table containing quota share, excess
of loss with 4M/1M layer and 3M/2M layer, including premium ceded, loss
cause, expense ceded, brokerage fee and profit margin (we require 10% as
reinsurer)
5. Date and Time of the Next Meeting
No meeting afterwards but we will keep contact with Mr Kapadia by email.
6. Close
Finish final calculation about exposure rating.

3. Progress Report
We are meeting by a conference call with mentor, he explained the data he provided
us and explain the work we need to do with our data also how to use the result in
further plan. Assumptions and adjustment examples are given in the call as well
61
4. Meeting Details
4.1 Explanation of Data
Mentor cleared our confusion with the data provided and deleted all the useless data
from table. The important data we are going to use are effective data, expiration date,
loss and expense and limit. We can ignore status since no matter what status the
claims have, they have potential.
We have three sheet so far. Policy listing are all losses while individual loss only
includes losses above $500k. The triangle sheet is for us to get the loss ratio. In terms
of individual loss, we are going to get increasing limit factors by seeing the changes
of premium based on different layers of limit so that we can use exposure rating. For
whole loss, we are using experience rating.
4.2 A Few of Steps on Data
First step is getting loss ratio based on triangle sheet. After that is working on large
loss which we are going to build in trend to loss by seeing how much historical loss
in these layers. Large loss won’t be used in quota share but only for excess of losses.
4.2 Tech in Data Analysis
Ultimate loss, loss development for triangle and exposure rating, experience rating
for reinsurance pricing will be used.
4.3 Assumption
Trend for premium, ceding commission, expense, rate changes for bringing the
premium on level. We need to give more weight on recent year if there are any
trend showing in the data.
4.3 Question
Q: where are we going to use the simulation?
62
A: We will use simulation after we decide the loss ratio for quota share and loss
cost for excess of losses. We will depend on the distribution but not point. Ceding
commission depends on the probability based on distribution. While we may don’t
have tail in our data. 5. Date and Time of the Next Meeting
The students and mentors will probably have a meeting in person on Next Thursday.

3. Progress Report
We had a call conference with mentor for discussion about our project. During
meeting, Mr. Kapadia sketched the whole experience rating and some detailed
knowledge about the trend in the calculation, which gave us an outline for the whole
experience rating calculation. After this, he talked about some concept about the
experience pricing and exposure rating, which cleared our confusion on the material
given last week
64
4. Meeting Details
4.1 Review of the project charter
In the last week, we have uploaded our midterm presentation and sent it to Mr.Kapadia.
After reviewing the whole midterm presentation, he gives us some feedbacks, which
indicating that there are some minor mistakes.
4.2 Explanation for the experience rating calculation
For quota share, we only do experience analysis but for excess of loss, we do both
experience rating and exposure rating. Firstly, given rate changes, we do group-up
experience analysis for projected loss ratio. With alternative loss ratio, we do
experience analysis and exposure analysis and look at different tricky options. After
that, we use simulation, determine distribution and compare different structure.
Data Needed:
- Historical WP or EP
- Historical Rate Changes
- Projected Rate Change
- Loss and exposure trend
- Individual losses / claims listing
- Excess loss development factors (usu. Derived if not available)
4.3 Supplement Comment
• Assumption is important for this calculation. We need to look at the industrial statistics
and assume some inflation rate for our calculation.
5. Date and Time of the Next Meeting
The students and mentors will have a conference call or in-person meeting on next
week.

3. Progress Report
We discussed the final presentations dates and details about the Experience rating and
the Exposure rating calculations for the Excess of loss reinsurance. Finally, we
discussed our plan to manage our time from now to the date of the final
presentation.
4. Meeting Details
4.1 Discussion about final presentation.
In our meeting with Professor Noor we found out that we will need to finish our
project and the final presentation one week before of the previously planned date. Our
mentor will be out of town for the last two weeks of the project with no internet access,
so we needed to discuss our progresses and the expected dates of each step in order to
meet the deadlines. We agreed on meeting next Thursday in person. In this meeting
we are planning to have a better understanding of the last steps and conclusions as well
as an outline of the final presentation.
66
4.2 Experience rating calculations.
By the time of our meeting we finished our experience rating calculations. We sent our
file to our mentor. We had questions about the how to calculate the losses in each layer
of the Excess of loss reinsurance. We are considering two layers, 3M xs 2M and 4M xs
1M. We agreed that we need first to trend the individual losses and then separate the
losses corresponding to our layers. The trend calculations for each loss will be from
January of each accident year to July 1st
of Ay 2016. After trending the losses we
aggregated them by accident year and then we applied the Loss development factors
calculated previously in our Gross Loss triangles used in the Quota Share calculation.
Then we applied the Chain Ladder and B-F method to obtain the Ultimate developed
losses. We used the on level premium also calculated previously in the Quota Share
analysis to obtained the Experience Loss cost,
4.3 Discussion on Exposure rating.
We discussed the theory involved in the Exposure rating and we concluded that it
would be easier to understand it if we see an example that Mr. Kapadia will share with
us and also discuss it in our in person meeting next week.
4.4 Discussion on in person meeting.
We agreed to try to meet at the Lamont campus next week. This will be our last
meeting with our mentor before the final presentation.

  • 4. 4 1. Executive summary Our objective is to build two models that price two types of reinsurance and evaluate the results. The reinsurance contracts analyzed are for a book of business in General Liability. We will look at Quota Share and Excess of Loss reinsurance contracts and take into consideration, profit, commissions, and different layers for the Excess of Loss reinsurance. 2. Introduction Reinsurance is the practice of insurers transferring portions of risk portfolios to other parties by some form of agreement in order to reduce the likelihood of having to pay a large obligation resulting from an insurance claim. By getting a reinsurance contract, the insurance company reduces the risks associated with underwritten policies, it can also spread the risks across alternative institutions. In our project we are taking the position of a Reinsurance company. The line of business that we are studying is General Liability which covers claims of bodily injury, physical injury, property damage, and advertising injury. It is sold to protect the businesses against incidents that may occur on the premises or at other locations where they conduct business. A Quota Share reinsurance is a proportional contract where one or more reinsurance companies take a stated percentage share of each policy that an insurer issues. The reinsurer will then receive a fixed percentage of the premiums and will pay the stated percentage of claims. In addition the reinsurer will allow a ceding commission to the insurer to cover the cost incurred by the insurer for acquisition and administration. Figure 2.1
  • 5. 5 An Excess of Loss reinsurance is a non-proportional reinsurance in the sense that it will only pay out if the total claims suffered by the insurer in a given period exceed a stated amount, which is called “retention” or “priority”. We analyze it on a per occurrence basis and consider two different contract layers: 3 million excess of 2 million and 4 million excess of 1 million. In the following figure we can see that the premium ceded to the reinsurance company is an amount set at the beginning of the contract. Figure 2.2 The General Liability data used in this analysis was provided by our Mentor, Mr. Kapadia, and correspond to a modified version of real data of an insurance company. ● Triangle of fifteen years of gross losses by accident year. ● Historical premium per year.. ● Rate changes. ● Limit profiles. ● Increased Limit factors (ILF). ● Earned premium. ● Trend. ● Individual claims listing.
  • 6. 6 Following we will describe the pricing methodologies for a Quota Share and an Excess of Loss reinsurance. 3. Quota share To price a Quota Share insurance we need to first take into consideration the historical loss ratios projected to the treaty period. The loss ratio is the ratio of expected ultimate losses and the adjusted historical premium. The expected ultimate losses is calculated using a Chain Ladder and the Bornhuetter-Ferguson method (B-F method) and the adjusted historical premium needs to be on leveled and trended using the parallelogram method. Then comes the decision that the ceding company takes in terms of the percentage of losses retained and the type and amount of ceding commission. The ceding commissions studied in this project are: ● Flat commission ● Sliding scale ● Profit commission ● Loss corridor commission. For the purpose of comparing the different models of reinsurance in this project we will use the Flat ceding commission. The ceding commission will be set by the insurance company, but as reinsurers we need to estimate a ceding commission that will consider the expected loss cost, expenses, brokerage fees and the profit that we are willing to get for this contract. Before committing to take the risk, the insurance company and the reinsurance company compare the expected loss ratios that each of them calculated based on the historical gross losses and they agree on the terms of the ceding commission. For this model we had the following information available: ● A triangle of General Liability ground up losses with 15 years of experience. ● Earned premium. ● Historical Rate changes. We have the following assumptions: ● Premium trending rate is 2%. ● Loss trending rate is 4%. ● No more loss development after 15 years. ● Interest rate do not change. A more detailed explanation of the calculations follows.
  • 7. 7 3.1 Loss development. The first step of pricing a Quota Share reinsurance is to obtain the ultimate losses by accident year. In order to do this, we use the Chain Ladder method and the Bornhuetter-Ferguson method (B-F method). 3.1.1. Chain ladder method This method operates under the assumption that patterns in claims activities in the past will continue to be seen in the future. The ground up losses in the triangle represent the incremental losses settled in the development year (column) for the given accident year (row). a) Age-to-age factor The age-to-age factor measures the changes of the development from one year to the next. It is calculated by taking the ratio of reported loss of chosen year to the previous year. For each of the age-to-age factors, we calculated different ways to obtain an average. We calculated the following average types: ● Geometric average: 𝐺𝑒𝑜𝑚𝑒𝑡𝑟𝑖𝑐 𝑎𝑣𝑒𝑟𝑎𝑔𝑒 = ∏ 𝑥𝑖 ● Median average: 𝑀𝑒𝑑𝑖𝑎 𝑎𝑣𝑒𝑟𝑎𝑔𝑒 = ∑ 𝑥𝑖 𝑛−2 𝑖=1 − min(𝑥𝑖) − max(𝑥𝑖) ● Volume weighted average: 𝑉𝑜𝑙𝑢𝑚𝑒 𝑤𝑒𝑖𝑔ℎ𝑡𝑒𝑑 𝑎𝑣𝑒𝑟𝑎𝑔𝑒 = 𝛴(𝐿𝑜𝑠𝑠𝑒𝑠 𝑎𝑡 𝑛 + 12, 𝑜𝑓 𝑡ℎ𝑒 𝑙𝑎𝑠𝑡 5 𝑦𝑒𝑎𝑟𝑠) 𝛴(𝐿𝑜𝑠𝑠𝑒𝑠 𝑎𝑡 𝑛, 𝑜𝑓 𝑡ℎ𝑒 𝑙𝑎𝑠𝑡 5 𝑦𝑒𝑎𝑟𝑠) ● Simple average: 𝑆𝑖𝑚𝑝𝑙𝑒 𝑎𝑣𝑒𝑟𝑎𝑔𝑒 = ∑ 𝑥 𝑛 We did not observe a significant variation in the prior methods of obtaining the average of the development factors. So, we decided to use the simple average as is is easier to interpret. We assumed that we won’t have loss development after 15 years then the tail age-to-age factor is 1. We observed that even though we were working with cumulative ground up losses there were some development years that had loss development factors less than one. This can happen due to the fact that the data includes some salvage and subrogation. This behavior was mostly present in older years and at more than 48 months of development. We decided to include them in the selected simple average to reflect this behavior.
  • 8. 8 Figure 3.1 b) Estimating Ultimate loss amounts The cumulative development factors (CDF) are used to measure changes of loss for each policy from certain accident year to ultimate loss. The Chain Ladder method calculates them for each accident year as the multiplication of the Loss development factors after the last period that the data was observed. The quantity further used in this analysis is the percentage of loss reported that is obtained as 1/CDF. Figure 3.2 3.1.2. Bornhuetter-Ferguson method (B-F method) The B-F method is used to calculate expected ultimate loss. Compared to the Chain Ladder method, B-F method it can avoid overreaction when unusual values appear. It is based on reported loss and the projected to ultimate loss calculated by the Chain Ladder method. As mentiones above, 𝑈𝑛𝑟𝑒𝑝𝑜𝑟𝑡𝑒𝑑 𝐿𝑜𝑠𝑠 = 𝑃𝑟𝑜𝑗𝑒𝑐𝑡𝑒𝑑 𝑡𝑜 𝑈𝑙𝑡𝑖𝑚𝑎𝑡𝑒 𝐿𝑜𝑠𝑠 ∗ (1 − 1 𝐶𝐷𝐹 ) Then the expected ultimate loss is the sum of reported loss and unreported loss.
  • 9. 9 3.1.3. Trending After obtaining the Ultimate losses per accident year we need to trend them. We assumed a loss trend of 4% per year. So we measured the length of trend from the average date in the corresponding accident year to the the average current date 07/01/2016. The adjusted ultimate loss is calculated as follows: 𝐴𝑑𝑗𝑢𝑠𝑡𝑒𝑑 𝑈𝑙𝑡𝑖𝑚𝑎𝑡𝑒 𝐿𝑜𝑠𝑠 = 𝐸𝑥𝑝𝑒𝑐𝑡𝑒𝑑 𝑈𝑙𝑡𝑖𝑚𝑎𝑡𝑒 𝐿𝑜𝑠𝑠 ∗ (1 + .04)𝑙𝑒𝑛𝑔𝑡ℎ 3.2 Premium development Steps 3.2.1 On-level premium The parallelogram method assumes that premiums are written evenly throughout the time period, it involves adjusting the aggregated historical premium by an average factor to put the premium on- level. We need to consider historical rate changes when we on-level the premiums. We had the following historical rate changes per year: Year Rate Change 2006 -3.0% 2007 -4.0% 2008 -5.0% 2009 -4.0% 2010 2.0% 2011 2.0% 2012 -0.5% 2013 -2.0% 2014 1.0% 2015 -1.0% Figure 3.3 The objective of the parallelogram method is to replace the average rate level for a given historical year with the current rate level. The steps for the parallelogram method are as follows: 1. Determine the timing and amount of the rate changes during the experience period. 2. Calculate the portion of the year’s earned premium corresponding to each rate level group. 3. Calculate the cumulative rate level index for each rate level group. 4. Calculate the weighted average cumulative rate level for each year. 5. Calculate the on-level factor as the ratio of the current cumulative rate level level index and the average cumulative rate level index for the appropriate year. 6. Apply the on-level factor to the earned premium for the appropriate year. To view the rate changes in a graphical format as in figure 3.4 assume that rate changes only impact policies written on or after the effective date therefore the rate change are represented by a
  • 10. 10 diagonal line, the slope of the line depends on the term of the policy for the purpose of this analysis they are one year policies. Figure 3.4 The on level factor formula is as follows: 𝑂𝑛 − 𝑙𝑒𝑣𝑒𝑙 𝐹𝑎𝑐𝑡𝑜𝑟 = 𝐶𝑢𝑟𝑟𝑒𝑛𝑡 𝐶𝑢𝑚𝑢𝑙𝑎𝑡𝑖𝑣𝑒 𝑅𝑎𝑡𝑒 𝐿𝑒𝑣𝑒𝑙 𝐼𝑛𝑑𝑒𝑥 𝐴𝑣𝑒𝑟𝑎𝑔𝑒 𝑅𝑎𝑡𝑒 𝐿𝑒𝑣𝑒𝑙 𝑖𝑛𝑑𝑒𝑥 𝑓𝑜𝑟 ℎ𝑖𝑠𝑡𝑜𝑟𝑖𝑐𝑎𝑙 𝑃𝑒𝑟𝑖𝑜𝑑 The numerator considers the most recent cumulative rate level index from Step 3. The denominator is the result of Step 4. 3.2.2. Premium trending We selected a one-step trending approach. The premium trend that we selected is 2%. The selected trend factor is used to adjust the historical premium to the expected levels. The trend period is typically measured as the length of time from the average date of policies with premium earned during the historical period to the average written date for policies that will be in effect during the time the rates will be in effect in this case 07/01/2016. The trending factor is defined as follows: 𝑇𝑟𝑒𝑛𝑑𝑖𝑛𝑔 𝑓𝑎𝑐𝑡𝑜𝑟 = (1 + .02) 𝐿𝑒𝑛𝑔𝑡ℎ 𝑜𝑓 𝑡𝑟𝑒𝑛𝑑 Each on-level premium is then multiplied by the trending factor to get the adjusted ultimate premium. The following is a summary table for the premium calculation.
  • 11. 11 Figure 3.5 3.3 Loss Ratio After getting the adjusted ultimate loss and the on-leveled and trended premium for each accident year, we get the loss ratio as follows: 𝐿𝑜𝑠𝑠 𝑟𝑎𝑡𝑖𝑜 = 𝐴𝑑𝑗𝑢𝑠𝑡𝑒𝑑 𝑈𝑙𝑡𝑖𝑚𝑎𝑡𝑒 𝐿𝑜𝑠𝑠 𝐴𝑑𝑗𝑢𝑠𝑡𝑒𝑑 𝑈𝑙𝑡𝑖𝑚𝑎𝑡𝑒 𝑃𝑟𝑒𝑚𝑖𝑢𝑚 We select the expected loss ratio as the average loss ratio of the 15 years of experience. This gives is a 54% Loss ratio.
  • 12. 12 Figure 3.6 3.4 Loss Ratio Distribution fitting Based on all the analysis above, now we have 15 years of historical loss ratios. As an exercise we wanted to get more information about the distribution of the loss ratio of this book of business. With the information available we have 15 years of experience.
  • 13. 13 AY Loss Ratio 2001 61.9% 2002 54.9% 2003 53.3% 2004 45.4% 2005 52.8% 2006 29.0% 2007 60.5% 2008 59.1% 2009 43.9% 2010 54.5% 2011 40.8% 2012 58.6% 2013 64.8% 2014 63.9% 2015 66.7% Figure 3.7 We use @risk software to fit a distribution to the loss ratio. Then based on the Akaike information criterion (AIC) criteria we compared the distributions and choose the one that had the lowest AIC criterion. Note: The Akaike information criterion (AIC) is a measure of the relative quality of statistical models for a given set of data. Given a collection of models for the data, AIC estimates the quality of each model, relative to each of the other models. Hence, AIC provides a means for model selection. The selected distribution is a Weibull distribution. Figure 3.8, shows it.
  • 14. 14 Figure 3.8 We found that the Weibull distribution is the best distribution to describe our 15 years historical loss ratio data. But the problem for this distribution is that this distribution has a light tail, which is not good enough to predict some extreme events. The reason behind this may be that our historical data size is not large enough, so we need to add one more extreme event in our dataset. We added one observation of 125% loss ratio to the 15 observations previously used. After adding this new observation we fitted the new distribution again and using the sale AIC criteria, we found that the Log-Logistic distribution is a good fit. Figure 3.9 The second best distribution is a Pearson5 Distribution. The Log-Logistic distribution has similar shape to the log-normal distribution but has heavier tails. In this analysis we can see that the Pearson5 distribution has a heavier tail than the Log-Logistic distribution. Even though that is the
  • 15. 15 case we would recommend the use of the Log-Logistic because its cumulative distribution can be written in closed form and it is known for it uses in economics and to measure survival analysis. We found this analysis very interesting and we got motivated to further investigate about the sensitivity of the pricing methods to the loss ratio and how this distribution can be used in replacing or complementing the Increased Limit Factors from the industry used in the Excess of Loss pricing analysis. 3.5 Treaty Features An important part of pricing a Quota Share reinsurance is to take into consideration the ceding commission. For our final analysis we used a Flat ceding commission but we also studied different types. Following are the description and examples of the commissions that can be considered in this type of reinsurance. 3.5.1. Sliding Scale Commission When there are disagreements between insurer and reinsurer, we may need to use the sliding scale commission to keep a balance between the insurer and reinsurer. Sliding scale commission ensures that the actual rate payable is directly related to the loss ratio, which means more commission in good years and lower commission in bad years. A common adjustable feature is the “sliding scale” commission. A sliding scale commission is a percent of premium paid by the reinsurer to the ceding company which “slides” with the actual loss experience, subject to set minimum and maximum amounts. We made 1,000 loss ratio simulations. In the calculation of the sliding scale commision, for each loss ratio simulated, we need to determine in which range the loss ratio falls into: below 50%, 50% - 60%, or above 60%. And then we apply the sliding scale to these loss ratio, and calculate the new average value of the 1,000 data, which is considered as the expected sliding commission. Figure 3.10
  • 16. 16 3.5.2.Profit commission A profit commission subtracts the actual loss ratio, ceding commission and a “margin” for expenses from the treaty premium and returns a percent of this as additional commission. Profit commission is the reward given to the insurance company for providing profitable business, by the reinsurer. Here is the formula: Profit = Premium – Loss - Commission-Reinsurer’s margin Profit Commission is payable in addition to ceding commission and applicable to proportional treaties and rarely seen in Non Proportional treaties. Figure 3.11 3.5.3.Loss Corridor The Insurance company will reassume a portion of the reinsurer's liability if the loss ratio exceeds a certain amount. A loss corridor provides that the ceding company will reassume a portion of the reinsurer’s liability if the loss ratio exceeds a certain amount. In our case the corridor is 25% of the Loss ratio layer from 65% to 75%. Figure 3.12
  • 17. 17 3.5.4 Flat ceding commission For the purpose of our project we will price a Quota Share insurance assuming a 25% of ceded losses. Meaning that the insurance company will retain 75% of the losses. For the purpose of the analysis we calculated a flat ceding commission taking into the following paraments: ● Expected loss ratio: 54% ● Brokerage fee: 2% ● Profit: 10% The calculation of the Flat ceding commision is as follows: 𝐶𝑒𝑑𝑖𝑛𝑔 𝐶𝑜𝑚𝑚𝑖𝑠𝑖𝑜𝑛 = 1 − 𝑃𝑟𝑜𝑓𝑖𝑡 − 𝐸𝑥𝑝𝑒𝑛𝑠𝑒 − 𝐵𝑟𝑜𝑘𝑒𝑟𝑎𝑔𝑒 𝐹𝑒𝑒 − 𝐸𝑥𝑝𝑒𝑐𝑡𝑒𝑑 𝑙𝑜𝑠𝑠 𝑐𝑜𝑠𝑡 Considering these parameters we obtained a Flat ceding commission of 29%. Expected Loss Cost $ 6,786,592 Brokerage Fee $251,350 Expenses $628,376 Ceding Commission $3,644,447 Profit $1,256,752 Premium ceded $12,567,516 Figure 3.13 4. Excess of Loss. 4.1. Pricing methods of Excess of Loss reinsurance. Exposure and experience rating are the most prevalent approaches to pricing excess of loss reinsurance contracts. They are frequently used together in a form of a credibility-weighted average to calculate the expected loss cost.
  • 18. 18 As mentioned before we consider two different layers for an Excess of Loss reinsurance: •3 x 2 Three million excess of two million. •4 x 1 Four million excess of one million. The assumptions used for both Experience and Exposure methods are: •Exposure trend for Premiums 2%. •Historical rate changes. •Loss trend 4%. •A tail factor 10% to the Loss Development Factor on each layer. 4.1.1. Experience rating The basic idea of experience rating is that the historical experience, adjusted properly, is the best predictor of future expectations. Experience rating uses historical losses of the ceding company. As we will be able to see in the case of the two layers studied in the project, there could be the case that no losses will fall in the layer and this will make the calculations of the expected loss cost less reliable. The information used in this analysis is on a per claim basis. The premium used was the one used in the Quota Share pricing, on leveled and trended. Below are the calculation’s steps. 1. Individual loss claims. Each of the ground up losses is trended to the future average date of loss in this case is 7/1/2016. The resulting loss is applied to the reinsurance layer. 2. For each claim calculate the loss corresponding to the layer to price and aggregate them by accident year. 3. Aggregated losses in the layer are then developed to ultimate. 4. Historical premium is adjusted for rate changes to the prospective premium level. 5. The loss cost of the layer by year is calculated by dividing the ultimate trended losses in the layer by the corresponding adjusted premium. 6. Then we calculate the average of the loss cost between the most recent years, 2006 to 2016. 7. The reinsurance rate is developed by loading the loss cost for the reinsurer’s expense and profit. In our analysis we can see that for the layer of 3 x 2 there are some years that do not have any losses falling in this layer. Whereas for the layer 4 x 2 all the accident years considered, from 2006 to 2015 have losses. Figure 4.1 shows the resulting Loss cost per layer.
  • 19. 19 Layer Experience Loss cost 3 x 2 5.62% 4 x 1 17.96% Figure 4.1 It seems that in the layer of 4x1 presents more losses in the layer than the 3 x 2 Excess of Loss reinsurance. In this case, we could say that is for this particular layer the Experience method is more “reliable”. In the appendix we show a summary table for both layers. 4.1.2. Exposure rating The exposure rating method relies on a current snapshot of the policies subject to the reinsurance contract. This snapshot will include some measure of the percentage of premium exposing the reinsurance contract, usually called the “Limit profile”, and an estimate of the gross loss, before reinsurance, for such policies. To perform an exposure rating we require a severity distribution, from which we can get the Increased Limit Factors (ILFs). We obtained these ILFs based on the industry benchmark provided by our mentor. The objective of the exposure rating method is to estimate the proportion of the loss for the underlying policy that is expected in the Excess of Loss layer. Exposure rating is suitable for those companies who have a book of business similar to the industry’s, for companies lacking data or having not reliable data. In this case, exposure rating might be the best way to obtain the expected loss cost since experience rating may not be very reliable. In this method all is based on in-force data without relying on historical one. The ILFs are defined as: 𝐼𝐿𝐹 = 𝐸𝑥𝑝𝑒𝑐𝑡𝑒𝑑 𝐶𝑜𝑠𝑡 𝑎𝑡 𝑡ℎ𝑒 𝑑𝑒𝑠𝑖𝑟𝑒𝑑 𝑝𝑜𝑙𝑖𝑐𝑦 𝑙𝑖𝑚𝑖𝑡 𝐸𝑥𝑝𝑒𝑐𝑡𝑒𝑑 𝐶𝑜𝑠𝑡 𝑎𝑡 𝑡ℎ𝑒 𝐵𝑎𝑠𝑖𝑐 𝐿𝑖𝑚𝑖𝑡 The Loss ratio is defined as the gross loss divided by the gross premium. The loss cost can be calculated using the loss ratio as in the following formula: 𝐿𝑜𝑠𝑠 𝑐𝑜𝑠𝑡 = 𝐺𝑟𝑜𝑠𝑠 𝐿𝑜𝑠𝑠 𝐺𝑟𝑜𝑠𝑠 𝑃𝑟𝑒𝑚𝑖𝑢𝑚 × 𝐶𝑒𝑑𝑒𝑑 𝐿𝑜𝑠𝑠 𝐺𝑟𝑜𝑠𝑠 𝑃𝑟𝑒𝑚𝑖𝑢𝑚
  • 20. 20 One way of calculating the loss cost is first calculate the Base premium that is the premium of the basic limit. We use the inforce premium by policy limit. The Base premium is calculated as follows: 𝐵𝑎𝑠𝑒 𝑝𝑟𝑒𝑚𝑖𝑢𝑚 = 𝑃𝑟𝑒𝑚𝑖𝑢𝑚 𝑜𝑓 𝑐𝑒𝑟𝑡𝑎𝑖𝑛 𝑝𝑜𝑙𝑖𝑐𝑦 𝑙𝑖𝑚𝑖𝑡 𝐼𝐿𝐹 𝑜𝑓 𝑡ℎ𝑒 𝑝𝑜𝑙𝑖𝑐𝑦 𝑙𝑖𝑚𝑖𝑡 Then to get the premium corresponding to the losses in the layer of interest, we multiply the Base premium by the difference of the upper and lower limit’s ILFs. 𝐴𝑑𝑗𝑢𝑠𝑡𝑒𝑑 𝑝𝑟𝑒𝑚𝑖𝑢𝑚 𝑜𝑓 𝑙𝑎𝑦𝑒𝑟 = (𝐵𝑎𝑠𝑒 𝑝𝑟𝑒𝑚𝑖𝑢𝑚) ∗ (𝑈𝑝𝑝𝑒𝑟 𝑙𝑖𝑚𝑖𝑡 𝐼𝐿𝐹 − 𝐿𝑜𝑤𝑒𝑟 𝑙𝑖𝑚𝑖𝑡 𝐼𝐿𝐹) We then multiply the adjusted premium of the layer to the expected loss ratio. To obtain the expected losses in the layer per policy limit. Part of the Exposure analysis is to take into consideration the ceding company’s limit profile. We obtain this by dividing each policy limit in force premium by the total inforce premium. Once we have the limit profile we multiply each of the expected losses by limit in the layer times its corresponding limit profile and then we add them all to obtain the expected loss cost. The expected loss cost for the layer 4x1 is 1.66% and for the layer 3x2 is 0.65%. Figure 4.2
  • 21. 21 4.2. Expected Loss cost. After calculating the experience and exposure loss cost we combine them in a form of credibility giving both methods the same weight. Figure 4.3 5. Conclusion Based on the analysis on the Quota Share and the Excess of Loss pricing , now we can give a final review and comparison for these two different reinsurance contracts. As part of the reinsurance contract our company will receive part of the premium from the ceding company and then we will take part of the risk involved. The main difference of these two types of reinsurance contracts is how to determine the part of the risk assumed. Here is a graph to show this concept: Figure 5.1 Assuming the percentage ceded in the case of the Quota Share and the limits in the case of the Excess of loss, we can discuss the final outcome for these two methods:
  • 22. 22 Figure 5.2 In summary, we have described the methods to price a Quota Share and an Excess of Loss reinsurance. We described the assumptions we made and how given a set percentage of profit we came up with a given ceded premium. For pricing purposes this is just a reference for the reinsurance company. In a real life scenario, the insurance company and the market will dictate the terms of the contract. This is when the different types of ceding commissions come into play as a tool for the reinsurance company to negotiate with the ceding company if their calculations of expected losses differ. There are many metrics to determine whether to write a treaty: loss ratio, dollars of profit, ceded premium, cost of capital, ROI to name a few. In this case we base our recommendations on profit. We assume 10% of profit for each contract. As we can see in Figure 5.2 the expected loss for the Quota Share is just 30% above the one expected for the 4x1 Excess of Loss reinsurance, and the profit is 87% higher that the 4x1 Excess of Loss contract. For this reason we come to the conclusion that recommending a Quota Share reinsurance is a reasonable start in the negotiations. For the two layers of the Excess of Loss reinsurance. We found that the layer of 3x2 had years where no data was available when calculation the Experience rating and the expected loss cost calculated may not be very reliable due to the lack of data. For this reason in the case that the insurance company may be interested in an Excess of Loss reinsurance we will recommend to quote a 4x1 layer. In general there are many factors that determine which kind of reinsurance the ceding company selects. For example, It can depend on the resources to write business to ensure profitability or how much surplus relief it needs.

The intent of reinsurance is for an insurance company to reduce the risks associated with underwritten policies by spreading risks across alternative institutions.

A General Liability insurance covers claims of bodily injury, physical injury, property damage, and advertising injury. It is sold to protect the businesses against incidents that may occur on the premises or at other locations where they conduct business.
  • 26. 26 Our objective is to come up with the best reinsurance structure for this book of business. We will look at Quota Share and Excess of Loss reinsurance contracts. We will take in to consideration, profit, commissions, and different layers for the Excess of Loss reinsurance. We plan to include sensitivity analysis as well as a detail list of all the assumptions needed to come up with the recommended rates per type of contact. Our project will include the following phases: 1. Data analysis: In this phase we will work on performing an exploratory analysis of the data, understand its structure and come up with the assumptions needed. During this phase we are also going to study the claim development methodologies as well as on leveling of premiums and trending both premiums and losses. The objective of this phase is to come up with and Ultimate loss and an estimated loss ratio. 2. Loss cost analysis: In this phase we plan to use the loss ratio of the prior phase and we are going to perform an Exposure and an Experience rating analysis. We will also add some simulations all this with the objective of obtaining the most “accurate” projected loss cost. 3. Pricing analysis: Use the projected loss cost to calculate for example for the Quota Share reinsurance the ceding commission to get this book of business profitable. We will analyze different limit scenarios for the Excess of Loss reinsurance. We will consider the possibility of adding treaty features and perform a sensitivity analysis with the objective of giving a profitable rate for our reinsurance company. Initial Project Milestones and Deliverables We are meeting with our mentor on a weekly basis. Prior to each meeting we will prepare a meeting agenda. We are currently in Phase 1 of our project. Our mentor has given us a list to literature to read related to pricing reinsurance contracts. We are in the process of getting data. Our mentor kindly has offered to provide us a dataset that most likely will include Loss experience, premium, expenses, of individual claims and some policy listings. In the meantime, we are reviewing the recommended literature and we plan to discuss any issues or exercises that will help us to get a better understanding of the theoretical procedures of the project.

  • 32. 32 of agreement in order to reduce the likelihood of having to pay a large obligation resulting from an insurance claim. The intent of reinsurance is for an insurance company to reduce the risks associated with underwritten policies by spreading risks across alternative institutions. In our project we are taking the position of a Reinsurance company. We are going to analyze a General Liability insurance. A General Liability insurance covers claims of bodily injury, physical injury, property damage, and advertising injury. It is sold to protect the businesses against incidents that may occur on the premises or at other locations where they conduct business. We will work on a pricing analysis for a Quota Share and an Excess of Loss reinsurance contracts with the objective to maximize the profit margins based on this book of business. A Quota Share reinsurance is a proportional contract where one or more reinsurers take a stated percentage share of each policy that an insurer issues. The reinsurer will then receive a fixed percentage of the premiums and will pay the stated
  • 33. 33 percentage of claims. In addition the reinsurer will allow a ceding commission to the insurer to cover the cost incurred by the insurer for acquisition and administration. An Excess of Loss reinsurance is a non-proportional reinsurance in the sense that it will only pay out if the total claims suffered by the insurer in a given period exceed a stated amount, which is called “retention” or “priority”. We are going to analyze it on a per risk basis. Scope and Objectives Our objective is to come up with the best reinsurance structure for this book of business. We will look at Quota Share and Excess of Loss reinsurance contracts. We will take in to consideration, profit, commissions, and different layers for the Excess of Loss reinsurance.

Approach and Threshold for Project Success
  • 34. 34 We got the following data for a GL line of business: A triangle of the Ground up reported losses and LAE as of 12/31/2015. For years 2001 to 2015 and experience of 15 years; We have GL individual Losses for claims that exceeded a $500,000 limit; and we also have available premium listings based on different GL limits. Some of the techniques that we are planning to implement are: In the loss ratio calculation we are going to determine the projected ultimate losses by using the ground up losses triangle and the Bornhuetter -Ferguson (B-F) Technique. For reinsurance pricing we will perform an Exposure rating technique using an Increase Limit Factors (ILF) method, and an Experience rating technique.
  • 35. 35 We will fit a curve to the expected loss ratio for a Quota Share and to the selected loss cost for the XL. We may use @Risk and R to fit and select the most appropriate loss distribution that will describe them. We will simulate the loss ratio and the selected loss cost to help us come up with suggested margins on negotiations while we consider treaty features. Assumptions and Constraints We will base our calculations on an Accident Year basis. For this we will consider the date of loss field in the data set. Although we will identify the assumptions once we start a more detailed analysis of the data. We consider that we will need to define them for the following steps on the project: Trends. Ceding commissions. Expenses. On-leveling the premium. Adjustments for historical rate changes. Determine the reinsurance treaty features. Decide if we are going to base our analysis on the most recent data or t he whole history. We may encounter some constraints in the simulation and curve fitting process since we lack a large amount of exposure years.

Students’ Address Mentors and students met in Science and Engineering Library. 2. Meeting Documents • Agenda for first weekly meeting • Project Plan 3. Progress Report We met in person in the Science and Engineering Library. In this first meeting our Mentor introduced some basic concepts about P&C reinsurance and we discussed the possible projects. After a discussion, we decided that our project will focus on an analysis of two types of reinsurance and we plan to build a pricing model from the reinsurance perspective that will evaluate a XL reinsurance and Quota Share reinsurance for the General Liability line of business. Some useful reading material is also given by our mentor for next following weeks.
  • 42. 42 4. Meeting Details 4.1 Explanation of Concepts In Reinsurance Our mentor explained two different types of reinsurance: Quota share reinsurance and excess loss reinsurance. For a general liability business, we are planning on considering a pricing model that will take in to consideration different structures that will be useful in negotiations with the insurance companies. 4.2 General Idea of Project Due to different characters shown in liability, such as loss ratio, we can set up a model and decide which type of reinsurance we should apply. To develop this, we need to look at historical record of book of business, determine what type of reinsurance structure we want to play with and project forward to get the fully developed loss, seeing how it goes under different type of reinsurance. Development triangle is require to realize this process. After collection and development of date, we can get a fitting distribution and their statistical character such as volatility, correlation and tail to decide whether it is a profitable scenario by simulation using software. Our project’s name could be “General liability reinsurance model”. 4.3 Supplement Comment  There are some features for quota share and excess of loss which are interesting. For quota share, ceding commission which is the fee reinsurance company need to pay to insurance for written expense need to be consider carefully cause there are always credit can be applied when disagreement happen. For excess of loss, there is a feature called risk statements, which is the cap of loss.  Risk attaching and loss occurring are two types of trending, one is related date when policies are written and the other one is related to when loss occurs.  There are two ways based on casualty pricing, one is based on experience which depend on annual book of business, the other on is based on exposure which is about individual risk. 4.4 Material Recommendation  Basic of reinsurance pricing is a very good article which introduce ways to price for property and casualty separately.  Presentation in CAS Website
  • 43. 43 4.3 Question: Citlalli Blanchet: What kind of data we need to get different scenario? Mentor: In terms of quota share reinsurance, we only need annual premium, expense and other general data from book of business but in terms of excess Jiawen Wu: Do we need to test our model? Mentor: I don’t think we need to worry that part. We can just assume the data are correct. I rather you focus on concept and modeling building. 5.

Progress Report We had Skype call with mentor for further discussion about our project outline. During meeting, Mr Kapadia sketched the whole project would be and all steps we are going to take, which gave us an outline for the whole process. After this, he talked about certain details in terms of our enquiry, which cleared our confusion on the material given last week.
  • 45. 45 4. Meeting Details 4.1 Description of Data Mentor would give us the data with premium, loss, expense and individual claims which we can analysis individual basis for loss policy, exposure rating, policy limits something like that. In terms of data, it will be consistent that premium, loss and large losses all go together. 4.2 Sketch for Whole Project For quota share, we only do experience analysis but for excess of loss, we do both experience rating and exposure rating. Firstly, given rate changes, we do group-up experience anaylsis for projected loss ratio. With alternative loss ratio, we do experience analysis and exposure analysis and look at different tricky options. After that, we use simulation, determine distribution and compare different structure. In terms of quota share, based on projected loss ratio and alternative loss ratio, we can decide the ceding commission and some adjustment for that. In terms of excess of loss, for different layer, we calculate exposure loss cost and compare it with experience loss cost. Based on these two loss cost, we can fit distributions based on them and compare their statistics feature. After comparison, we can make decision on it. 4.3 Supplement Comment  Assumption is important for this project. We need to list all the assumptions to from chain ladder to why we switch from experience analysis to exposure analysis.  Sensitivity test is needed to see how the number changes when assumption twisted.
  • 46. 46 4.3 Question: Jiawen Wu: Catastrophe for local enterprise will have huge impact but for international will be small. So which type are we going to have? Mentor: We only consider general liability. So the catastrophe impact will be minimum since they only affect property which is third-party coverage. Citlalli Blanchet: How do we know whether the exposure analysis or experience analysis to choose? Mentor: We need to look at the assumptions. For experience analysis, the company should be stable, which means no much changes within a long period. For those companies who raised their policy limits, shifted their area, exposure analysis would be more suitable. Zijun Chen: Could you explain more about exposure rating? Mentor: Exposure rating only depends on in-force exposure. Loss costs are only calculated by increasing factor, which is nothing to do with historical loss as well.

Progress Report We are meeting by a conference call with mentor, he gave us a few advices for our presentation draft for mid-term have corrected the ceding commission calculation last week. Next week we are going to have mid-term presentation.
  • 49. 49 4. Meeting Details 4.1 Advice for Mid-Term Presentation Draft Mr Kapadia suggested us to change our title as reinsurance pricing rather than pricing quota share and excess of loss reinsurance to avoid too much unnecessary details. he thought we should give the conception of reinsurance at the beginning rather than in front of quota share pricing methodology. He give us an example outline for our presentation: conception of quota share and excess of loss, objective of pricing, factors we taking into consideration, project basis, summary to show result for quota share then the methodology used. In terms of excess of loss, we don’t need to go into details since we haven’t touched yet. 4.2 Correction of Ceding Commission calculation 4.2.1 Sliding Scale Frist of all, Jiawen explained how we got the ceding commission by sliding scale commission, profit commission and loss corridor respectively. Then Mr Kapadia give his option for each method. For sliding scale commission, we only use one sliding between the commission we want to pay as a reinsurer (minimum) and the fee the reinsured want to receive (maximum). We decide to use 30%-40% as bound. For sliding rate, 1:1 is assumed. We don’t need to consider ultimate profit at first but sliding is needed at the beginning. For convenience, we need to use have 1000 simulation for loss ratio and ceding commission calculated by each method so that we can see the changes of ceding commission when loss ratio distribution changed. We don’t need to consider expense and brokerage for sliding scale commission. We can use middle point of bounds to check our result because the final expected ceding commission should be nearly there. 4.2.2 Profit Commission In terms of profit commission, brokerage which is the agency fee for broker between reinsurance company and insurance company (for quota share, we assume 2% and for excess of loss, we assume 10%) and margin (we can chose between 10%-15%) is needed which is the expense for reinsurance company. The ceding commission reinsurance company want to pay, loss ratio distribution, flat commission and margin should be decided at the beginning. After we decide the percent return, the final commission is the sum of flat commission and percent return. Low ceding commission can be chosen as 30%. If the actual profit is negative, not profit returned needed. 50% percent return is suggested.

During meeting, Mr. Kapadia sketched the whole triangle calculation method and some detailed knowledge about the trend in the calculation, which gave us an outline for the whole triangle loss calculation. After this, he talked about some concept about the experience pricing and exposure rating, which cleared our confusion on the material given last week.
  • 52. 52 4. Meeting Details 4.1 Review of the project charter In the last week, we have uploaded our project charter and sent it to Mr.Kapadia. After reviewing the whole project charter, he gives us some feedbacks, which indicating that there are some minor mistakes and he will send an email about the suggestion of the project charter in the next week. 4.2 Explanation for the triangle calculation For quota share, we only do experience analysis but for excess of loss, we do both experience rating and exposure rating. Firstly, given rate changes, we do group-up experience analysis for projected loss ratio. With alternative loss ratio, we do experience analysis and exposure analysis and look at different tricky options. After that, we use simulation, determine distribution and compare different structure. When we calculate the loss ratio, we need to use the triangle method. Here are some steps for this method: Step1–Compile claims data in a development triangle Step2–Calculate age-to-age factors Step3–Calculate averages of the age-to-age factors Step4–Select claim development factors Step5– Select tail factor Step6–Calculate cumulative claim development factors Step7–Project ultimate claims 4.3 Supplement Comment • Assumption is important for this calculation. We need to look at the industrial statistics and assume some inflation rate for our calculation.
  • 53. 53 4.3 Question: Zijun Chen: There are some age-to-age factors smaller than 1. When we take the average of these factors, how to deal with those values? Mentor: We take average of all the values. If the final outcome is larger than 1, we just keep it, otherwise, we use 1. Zijun Chen: When we do the triangle calculation, the loss ratio is too large, it seems something goes wrong. Mentor: When we check the excel file, there is a mistake in the vba code. After fixing the code, this problem should be solved. Zijun Chen: The trends used on premium and loss haven't been decided. Mentor: We assume the loss trend is 4% , and we need to adjust the project loss.s

We talk about the approach that we were going take in our midterm presentation. We also talk about some modifications that we need to add the gross loss triangle calculations. Finally, we discuss the simulation process and the use of the @Risk software.
  • 56. 56 4. Meeting Details 4.1 Comments on Project Charter We currently have the project in three phases: 1.- Data analysis 2.- Loss cost analysis. 3.-Pricing analysis. Mr, Kapadia suggested to have the phases more like 1.-Data analysis and projecting Ground up losses. 2.- Pricing of Excess of Loss and Quota Share reinsurance. 3.-. Final decisions and over all summary result analysis. We agreed that we will decide on the best split of the phases in the future but this could be the approach that we should be taking. 4.2 Midterm presentation discussion. The midterm presentation is due in two weeks, we talk about the approach that we should take and what topics should we mention in more detail. Mr. Kapadia suggested presenting an overview of the project by giving an introduction to reinsurance, explaining what General Liability is and defining the types of reinsurance that we are planning to price. Then give definitions and examples of Excess of Loss and Quota share insurance and comment on the assumptions. Since for the Quota Share reinsurance we have already been working the Gross Loss triangle we can explain a little more in detail our results and calculations. Then we can give an introduction to the treaty features that we are applying and their definitions. For the Excess of loss insurance we can give an introduction of the pricing plan and talk about the data available for this analysis. We can also show a list of assumptions that we so far have used and the one we will need to consider. In general to give a non to technical presentation of our project but that at the same time will give a clear overview of our progress and our objectives. 4.3 Discussion on Gross Loss Triangle calculations. We suggested to add different averages and methods of obtaining the Loss Development Factors because in our data we have some years with salvage and subrogation. We agreed to add these calculations and discuss our finding in our next meeting. 4.4 Discussion on Simulation on Loss Ratios.
  • 57. 57 We agreed that the software @Risk is our best option to work with simulations and tests of distributions that best fit our data. We agreed that we all are going to come up with some data analysis and discuss our finding in our next meeting. We all need to get more familiarized to @Risk. We all are very interested in learning how to use it since is a software that is commonly used in the reinsurance industry. We discussed options on how to come out with our results. Like what happens if we add some catastrophic losses. Try different approaches in terms of tests and simulations. 4.5 Discussion about commissions. We discussed how to add a sliding scale commission. And then how to get our profit and what can be a reasonable profit commission all based on the simulations of the Loss Ratios. And we want to calculate the expected value of this commission. We also wanted to discuss reasonable profit limits. Mr. Kapadia suggested to add a table with the expected losses and the different commission that we will consider.

ILFs are also given for each layer’s base premium. 4.2 Sketch for Whole Project In order to get loss ratio for 4M/1M and 3M/2M reinsurance policy, we need to calculate adjusted premium for each layer separately. We can get base premium by dividing ILFs from premium and multiple the difference between upper limits and lower limits, which is decide by both layer and policy limit, we get premium for each layer. We assume each layer has loss ratio 55%. By applying this loss ratio, we get expected loss for each layer. Percentage of premium compared with totally premium multiple corresponding expected ratio is the total expected loss for each layer. We sum them up then we get the ultimate loss for 4M/1M and 3M/2M layer individually. Since we have loss ratio from both exposure rating and experience rating, we weigh two values and come up a credible loss ratio for excess of loss based of in- force policy and historical policy. In order to compare quota, share and excess of loss, we need to consider qualitatively as well beside volatility, profit margin and other consideration. We are going to have a table containing quota share, excess of loss with 4M/1M layer and 3M/2M layer, including premium ceded, loss cause, expense ceded, brokerage fee and profit margin (we require 10% as reinsurer) 5. Date and Time of the Next Meeting No meeting afterwards but we will keep contact with Mr Kapadia by email. 6. Close Finish final calculation about exposure rating. 06/08/2016 Recorded by Zijun Chen

Progress Report We are meeting by a conference call with mentor, he explained the data he provided us and explain the work we need to do with our data also how to use the result in further plan. Assumptions and adjustment examples are given in the call as well
  • 61. 61 4. Meeting Details 4.1 Explanation of Data Mentor cleared our confusion with the data provided and deleted all the useless data from table. The important data we are going to use are effective data, expiration date, loss and expense and limit. We can ignore status since no matter what status the claims have, they have potential. We have three sheet so far. Policy listing are all losses while individual loss only includes losses above $500k. The triangle sheet is for us to get the loss ratio. In terms of individual loss, we are going to get increasing limit factors by seeing the changes of premium based on different layers of limit so that we can use exposure rating. For whole loss, we are using experience rating. 4.2 A Few of Steps on Data First step is getting loss ratio based on triangle sheet. After that is working on large loss which we are going to build in trend to loss by seeing how much historical loss in these layers. Large loss won’t be used in quota share but only for excess of losses. 4.2 Tech in Data Analysis Ultimate loss, loss development for triangle and exposure rating, experience rating for reinsurance pricing will be used. 4.3 Assumption Trend for premium, ceding commission, expense, rate changes for bringing the premium on level. We need to give more weight on recent year if there are any trend showing in the data. 4.3 Question Q: where are we going to use the simulation?
  • 62. 62 A: We will use simulation after we decide the loss ratio for quota share and loss cost for excess of losses. We will depend on the distribution but not point. Ceding commission depends on the probability based on distribution. While we may don’t have tail in our data. 5. Date and Time of the Next Meeting The students and mentors will probably have a meeting in person on Next Thursday. 6. Close Students prepare for the Project Chapter and send it to mentors. 16/6/2016 Recorded by Zijun Chen

Progress Report We had a call conference with mentor for discussion about our project. During meeting, Mr. Kapadia sketched the whole experience rating and some detailed knowledge about the trend in the calculation, which gave us an outline for the whole experience rating calculation. After this, he talked about some concept about the experience pricing and exposure rating, which cleared our confusion on the material given last week
  • 64. 64 4. Meeting Details 4.1 Review of the project charter In the last week, we have uploaded our midterm presentation and sent it to Mr.Kapadia. After reviewing the whole midterm presentation, he gives us some feedbacks, which indicating that there are some minor mistakes. 4.2 Explanation for the experience rating calculation For quota share, we only do experience analysis but for excess of loss, we do both experience rating and exposure rating. Firstly, given rate changes, we do group-up experience analysis for projected loss ratio. With alternative loss ratio, we do experience analysis and exposure analysis and look at different tricky options. After that, we use simulation, determine distribution and compare different structure. Data Needed: - Historical WP or EP - Historical Rate Changes - Projected Rate Change - Loss and exposure trend - Individual losses / claims listing - Excess loss development factors (usu. Derived if not available) 4.3 Supplement Comment • Assumption is important for this calculation. We need to look at the industrial statistics and assume some inflation rate for our calculation. 5. Date and Time of the Next Meeting The students and mentors will have a conference call or in-person meeting on next week. 6. Close Students prepare to complete the triangle calculation and send it to mentors. 23/7/201 Recorded by Jiawen Wu

Meeting Documents • Agenda for meeting. • Experience rating calculations. 3. Progress Report We discussed the final presentations dates and details about the Experience rating and the Exposure rating calculations for the Excess of loss reinsurance. Finally, we discussed our plan to manage our time from now to the date of the final presentation. 4. Meeting Details 4.1 Discussion about final presentation. In our meeting with Professor Noor we found out that we will need to finish our project and the final presentation one week before of the previously planned date. Our mentor will be out of town for the last two weeks of the project with no internet access, so we needed to discuss our progresses and the expected dates of each step in order to meet the deadlines. We agreed on meeting next Thursday in person. In this meeting we are planning to have a better understanding of the last steps and conclusions as well as an outline of the final presentation.
  • 66. 66 4.2 Experience rating calculations. By the time of our meeting we finished our experience rating calculations. We sent our file to our mentor. We had questions about the how to calculate the losses in each layer of the Excess of loss reinsurance. We are considering two layers, 3M xs 2M and 4M xs 1M. We agreed that we need first to trend the individual losses and then separate the losses corresponding to our layers. The trend calculations for each loss will be from January of each accident year to July 1st of Ay 2016. After trending the losses we aggregated them by accident year and then we applied the Loss development factors calculated previously in our Gross Loss triangles used in the Quota Share calculation. Then we applied the Chain Ladder and B-F method to obtain the Ultimate developed losses. We used the on level premium also calculated previously in the Quota Share analysis to obtained the Experience Loss cost, 4.3 Discussion on Exposure rating. We discussed the theory involved in the Exposure rating and we concluded that it would be easier to understand it if we see an example that Mr. Kapadia will share with us and also discuss it in our in person meeting next week. 4.4 Discussion on in person meeting. We agreed to try to meet at the Lamont campus next week. This will be our last meeting with our mentor before the final presentation.
