"Fracking" is the practice of shooting liquid into shale deposits in the ground in order to widen and hold open cracks in the shale so that natural gas trapped in the shale can flow into sunken pipes and be extracted as fuel. There is a lot of fracking going on in Central Pennsylvania because of our large Marcellus Shale shield.

The liquid that is pumped into the shale contains toxic chemicals, notably benzene which is a causal factor in acute myeloid leukemia. Because the population of Central PA is at greater risk of leukemia from gas industry practices, the insurance companies that provide health insurance to this population would like to rate their premiums to cover the increased risk and increased cost.

Before the natural gas companies came to Central Pennsylvania and changed the health status of the people living there, 100% of the households in one county had employer-paid health insurance. The fair premium per family was $8300 per year, and every policy required each family to pay 20% of their own expenses while the insurance company covered the other 80%. There were also loading factors that we will ignore although they are included in the premium charged to the employer. We are interested in knowing how the premium must change to account for the increased risk of AML and how the cost to the insured (as a deductible) is likely to change.

The $8300 premium that is currently being paid is "sunk cost." It already includes the average risk of AML for the population throughout the nation and should not be included in our calculations. We are interested only in calculating the increased risk and increased cost for this particular population, and determining the rating that must be added to the existing premium to cover this new precondition.

The increase in prevalence rate for AML and the cost of treating each case of AML are given in your question set. They are sufficient to calculate the rating as an Expected Value. This rating would then be added on to the $8300 annual payment that employers are already paying.

Question 1: What is the Expected Value Cost of AML to individuals living in the County? (show calculations)

Question 2: How should health insurance policies in the County be rated?

What is the EV Cost per household? (show calculations)

What is the rating on the premium, at 80% of the EV Cost per household? (show calculations)
