In Year 1, Company X began to receive complaints from physicians that patients were experiencing unexpected side effects from the companys sleep apnea drug. The company took the drug off the market near the end of Year 1. During Year 2, the company was sued by1,000 customers who had had a severe allergic reaction to the companys drug and required hospitalization. At the end of Year 2, the companys attorneys estimated a 60 percent chance the company would need to make payments in the range of $1,000 to $5,000 to settle each claim, with all amounts in that range being equally likely. At the end of Year 3, while none of the cases had been resolved, the companys attorneys now estimated an 80 percent probability the company would be required to make payments in the range of $2,000 to $7,000 to settle each claim. In Year 4, 400 claims were settled at a total cost of $1,2 million. Based on this experience, the company believes 30 percent of the remaining cases will be settled for $3,000 each, 50 percent will be settled for $5,000, and 20 percent will be settled for $10,000.
