The consequences of the warranties offered by DualSun are insured for 10 years by an insurance contract with the company Chubb (via a subsequent 10-year warranty that covers all equipment sold by DualSun). This means that even in case of failure of DualSun, the named insurer could take over DualSun's insurances for a period of 10 years after failure. Chubb is the world's largest publicly traded P&C insurance company.
NB: Subsequent Coverage is the coverage that remains after a policy has been terminated. When the coverage is based on the victim's claim, the coverage normally terminates on the date the policy is terminated. However, the subsequent guarantee can be activated in the event of the insured's cessation of activity, in this case DualSun.
