Which One To Choose?

I have encountered many kinds of insurance like Health, Disability, Casualty, Life, Property, Liability, Credit Insurance and so one and so forth. But it's only now that I heard about key man insurance, are you familiar with these? Well based from what I have read it's "designed to compensate a company for the loss of a very important employee. Those of us in this kind of business know our employees are our most important assets. The untimely death of a key person in any business can be devastating." So know now, that there's kind of insurance too.
