Welcome! I don't know much about equine insurance. Do you do actuary studies and all to create the premium rates?
Is it for injury or only for death. And is it based on the horse's value on the open market?
We cover both death and injury. It's based on the total insured value of the horse, which may be more or less than its value on the open market. The actuarial studies that have been done have been woefully inadequate, since we only consider the breed of the horse and its use (racing, show, etc) when we compute premium. Clearly we should take a lot of other things into account, like the horse's medical history and whether its ancestors had any serious conditions.
