The kind of coverage you receive:
We will pay for the following on a secondary basis:This coverage is not all-inclusive, which means it does not cover such things as personal injury, personal liability, or personal property. It does not cover you for any damages to other vehicles or property. It does not cover you for any injury to any party.

Coordination of Benefits:
When MasterRental is provided on a secondary basis and a covered loss has occurred the order in which benefits are determined is as follows:

1. You or any authorized driver's primary auto insurance;
2. Collision/damage waiver provided to you by the rental agency;
3. Any other collectible insurance;
4. The coverage provided under this EOC.

If you or an authorized driver's primary auto insurance or other coverage has made payments for a covered loss, we will cover your deductible and any other eligible amounts, described in the section "The kind of coverage you receive", not covered by the other insurance.

Note: In certain parts of the United States and Canada, losses to rental vehicles that are covered by your personal vehicle insurance policy liability section may not be subject to a deductible, which means that you may not receive any benefits from this program. Contact your insurance provider for full coverage details pertaining to your personal vehicle liability insurance policy (or similar coverage).

If you have no other insurance or your insurance does not cover you in territories or countries outside of the United States, coverage is considered primary coverage.

Having said that, many US-issued cards which are "secondary" are only secondary in the US, and become primary internationally.
