C. Paragraph 5. of the Cancellation Common Policy Condition is replaced by the following:

5. If this policy is cancelled, we will send the first Named Insured any premium refund due. If we cancel, the refund will be pro rata. If the first Named Insured cancels, the refund may be less than pro rata. If the return premium is not refunded with the notice of cancellation or when this policy is returned to us, we will mail the refund within 15 working days after the date cancellation takes effect, unless this is an audit policy.

If this is an audit policy, then, subject to your full cooperation with us or our agent in securing the necessary data for audit, we will return any premium refund due within 90 days of the date cancellation takes effect. If our audit is not completed within this time limitation, then we shall accept your own audit, and any premium refund due shall be mailed within 10 working days of receipt of your audit.

The cancellation will be effective even if we have not made or offered a refund.

D. The following is added and supersedes any other provision to the contrary:

Nonrenewal

1. If we decide not to renew this policy, we will mail or deliver to the first Named Insured written notice of nonrenewal, accompanied by the reason for nonrenewal, at least 45 days prior to the expiration of this policy.

2. Any notice of nonrenewal will be mailed or delivered to the first Named Insured at the last mailing address known to us. If notice is mailed, proof of mailing will be sufficient proof of notice.
