You pay your employees a bonus for every person the employee gets to purchase a trip. Without any encouragement from you and without your knowledge, one of your employees gets ambitious and invites his friends to a party in which he will show pictures from previous trips. On the way to the party, one of the friends gets in a car wreck and dies. His spouse sues your company.

a. Is your company liable?

b. Would it matter if you know about the party ahead of time?
