RETURN OF PREMIUM CLAUSE

In the event of the gross profit earned (or a proportionately increase multiple thereof when the maximum indemnity period exceeds twelve months) during the accounting period of twelve months most nearly concurrent with any period of insurance, as certified by the Insured's auditors, being less than the sum insured thereon a pro rata return of premium not exceeding 50 percent of the premium paid on such sum insured for such period of insurance will be made in respect of the difference. If any damage shall have occurred, giving rise to a claim under this Policy, such return shall be made in respect only of so much of the said difference as is not due to such damage.
