No offense taken, it's just that the comparison of our Program and AMIG's offering is not on an "apples-to-apples" basis---which is completely fine. Especially pertaining to pricing, as the proposal we sent was based upon five locations, not the 100 or so you have. As you would imagine, pricing for 100 properties is usually much better than 5. I re-proposed based upon this, and on the one locations (assuming we did all 100), the cost was a little less than $100 difference total.
As for "co-insurance", here is a layperson's/simplified synopsis:
What is Co-insurance?
“Co-insurance is a policy provision used to encourage you, the insured, to purchase and maintain insurance to an acceptable value. The Co-insurance clause will state that you must carry an insurance limit on the property in an amount greater than or equal to a certain percentage of its total reconstruction value. The most common requirements are 80%, 90% or 100%. In a claims situation, the reconstruction cost of the property would be determined at the time of loss. If the amount you are insured to is less than the required amount, based on percentage, then the difference will be levied against your settlement in addition to the deductible and any applicable depreciation."
Part of the reason that AMIG requires higher insured values (in many cases much higher than the actual value of the property) is to avoid any penalties as described above. In our Program, as long as you are insured to $45/square foot (which is ACV--$65 for RC), there is NO co-insurance requirement. Granted, if the value to rebuild your location is $200,000, then by all means, insure it accordingly, especially if your plan is to rebuild it. However, if the actual value (to sell, for instance) is much less, as long as you avoid co-insurance and garner RC claims settlement parameters (by insuring in our Program as I just described), you can further drive down your costs without sacrificing needed coverage/protection. In other words, if your location is "worth $100,000, and $100,000 of coverage meets our co-insurance waiver provisions, insuring it to $200,000 is really just costing you additional premium of which you'd receive no benefit (unless your property is in a "Value Policy" state, which Colorado is not, last I checked).
Sounds like you've had a good experience with them. My partner and I used them in Ohio for a few years (over 400 locations), and also had similar experiences. About 4 years ago or so (in Ohio, at least at that time), they changed their underwriting guidelines, including requiring higher limits than "realistic" property values and inspections, so we switched. Hope this helps...
