Peak Season Endorsement

A peak season endorsement is a property endorsement that automatically raises the limit on business personal property — typically inventory — during defined periods when a business predictably stocks up. Many businesses carry far more merchandise during a few weeks or months (retailers before the holidays, garden centers in spring, costume shops before Halloween) than during the rest of the year. Insuring year-round to the seasonal peak wastes premium, while insuring to the off-season average leaves the business badly underinsured during its busiest, highest-value weeks. This endorsement solves that by scheduling a higher limit for specified dates.

For a small-business buyer, the value is twofold: adequate protection when the most inventory (and revenue) is on the line, and no premium paid for coverage you do not need in slow months. It also helps satisfy coinsurance requirements during the peak, since being underinsured at the time of loss can trigger a coinsurance penalty that reduces your claim payment. The endorsement can specify multiple peak periods and can be tied to a percentage increase or a stated additional amount above the base limit.

A practical nuance: the higher limit only applies during the exact dates listed, so accuracy matters — if your buildup starts earlier than scheduled or a shipment arrives ahead of the window, a loss during the gap is covered only to the base limit. Buyers should base the peak amount on their true maximum inventory value, review the dates each year as buying patterns shift, and consider pairing this with blanket insurance if inventory moves among multiple locations. Confirm whether the endorsement covers stock in transit or only at the described premises.
