Attached is some Risk Management / financial information regarding a company that has traditional state workers compensation coverage. I am struggling to understand how to complete a financial analysis as to suggest a different alternative risk transfer program, i.e. self insurance, captive or large deductible program. How is WACC helpful here as well?
