3. Page 3 Recording of this session via any media type is strictly prohibited. MATH Matters Question…  Do you review the calculations?  How do you use the actuarial report?  Do you grab the first number and close the report?

4. Page 4 Recording of this session via any media type is strictly prohibited. MATH Matters Not a bad strategy if: 1.You need a number for a financial statement 2.You need the loss pick for a meeting 3.Your broker handles that stuff

5. Page 5 Recording of this session via any media type is strictly prohibited. MATH Matters A bad strategy if: Actually, that is always a bad strategy – there is a lot more there the MATH is telling you.

6. Page 6 Recording of this session via any media type is strictly prohibited. MATH Matters Use the actuarial analysis as part of your stewardship report to the CFO, Board, … Use the MATH to show what has happened and what is expected to happen. The losses are x% of the program, so the MATH to get to that x% is important.

7. Page 7 Recording of this session via any media type is strictly prohibited. MATH Matters - Assumption – You are getting a reserve analysis and a loss projection. - You need at least two numbers – the estimated reserves and the loss pick. - How many more are there?

8. Page 8 Recording of this session via any media type is strictly prohibited. MATH Matters LOTS – let’s look at the MATH… Look at the reserves first: Reserves = Case Reserves + IBNR

9. Page 9 Recording of this session via any media type is strictly prohibited. MATH Matters o If the IBNR to case reserve ratio has been increasing, then the reserve position MAY be stronger. o If the ratio is decreasing, then the reserve position MAY be getting weaker.

10. Page 10 Recording of this session via any media type is strictly prohibited. MATH Matters It is good to know the MATH so you can figure out if a potential problem is looming or if you are now in a stronger position. A large claim can give an unusual ratio. Stronger reserving can give an unusual ratio.

11. Page 11 Recording of this session via any media type is strictly prohibited. MATH Matters Still looking at reserves: What is your range? There is one whether it is shown or not! It should not be large! It will not give you every possible outcome.

12. Page 12 Recording of this session via any media type is strictly prohibited. MATH Matters Reserve Range: The range gives you an opportunity to fund something different, but within a reasonable range. The MATH will let you know what is reasonable.

13. Page 13 Recording of this session via any media type is strictly prohibited. MATH Matters Let’s look at the loss pick: Do you get one number? OK Do you get a range? Better Do you get confidence intervals? Best - MAYBE

14. Page 14 Recording of this session via any media type is strictly prohibited. MATH Matters Loss Pick (Simple Example): o Pure Loss Rate x Exposures o Exposures should be easy o MATH Matters when calculating the pure loss rate

15. Page 15 Recording of this session via any media type is strictly prohibited. MATH Matters For each policy period:  Incurred/paid losses are developed to ultimate  Ultimate losses are trended to a common period  Exposures are trended to a common period MATH Matters for each step

16. Page 16 Recording of this session via any media type is strictly prohibited. MATH Matters  Do you understand how the ultimate losses are calculated?  Are the exposures appropriate and correct?  Are the trend factors reasonable?

17. Page 17 Recording of this session via any media type is strictly prohibited. MATH Matters Pure Loss Rate: Trended Losses / Trended Exposures  A pure loss rate for each policy period.  How variable? You need this for TCOR!  Is selected rate reasonable?

18. Page 18 Recording of this session via any media type is strictly prohibited. MATH Matters Loss Pick  How is the range calculated?  Does it seem reasonable?

19. Page 19 Recording of this session via any media type is strictly prohibited. MATH Matters Loss Pick MATH Matters – what is a confidence interval? The confidence interval tells you the probability an amount will not be exceeded. What is the “correct” percentile?

20. Page 20 Recording of this session via any media type is strictly prohibited. MATH Matters What do you need to know? + Addition - Subtraction X Multiplication ÷ Division

21. Page 21 Recording of this session via any media type is strictly prohibited. Take Aways…  TCOR – use projected losses and confidence intervals  Metrics – pure loss rate, frequency, severity  Confidence Interval – choice of program
