The insured under a Commercial General Liability policy rents an additional warehouse. He would be covered without notice to the agent or the insurer for which of the following?
Choose one answer.
 a. 90 days 
 b. Remainder of the policy term  (correct answer)
 c. 60 days 
 d. 30 days 

In the book, on page 122... If the named insured acquires or forms another business (other than a artnership, joint venuture, or limited liability company) during the policy term, such an organization becomes a named insured for 90 days, but only as to events which occur after the acquisition.  In sured status does not apply to anyone for a partnership, joint venture or limited liability company not shown as a named insured in the declarations.

 
Is there a difference between who is an insured as opposed to what property is insured in regards to notification to the insurer?
