Answer:
The manager wants documentary evidence that self insurance reduced cost than that which would have been incurred if the company used third party insurance services.
Step-by-step explanation:
Self insurance is defined as a situation where a business does not engage services of a third party insurance company, but rather bears some of the risk of loss. For example when a company bears health costs.
In this instance the company has decided to self insure with respect to worker's compensation loss exposure.
A business that self ensures during a hard insurance market wants to reduce the amount it will pay on premiums to insurance companies. Also underwriting standards are tighter.
The risk manager wants to prove that self insurance comes at a reduced cost to the company. This evidence will be presented to insurance underwriters and be used to gain lower Premium. That is why he said "So we have a good story to tell an insurance company next year."
