BUSINESS INCOME ALTERNATIVES TO COINSURANCE

(December 2025)

INTRODUCTION

The Insurance Services Office (ISO) Business Income Coverage Forms CP 00 30 and CP 00 32 are subject to the coinsurance additional condition. The named insured receives a rate credit for insuring the property at its value. However, at the time of loss, it is penalized if the selected limit is less than the limit that would satisfy the coinsurance additional condition.

Example: Poppy’s Pop Sticks had net income and continuing operating expenses of $150,000 last year. Poppy doesn’t anticipate any major changes and estimates his sales will increase to $160,000 this year. As a result, he tells his agent to use a 50% coinsurance limit of $80,000.

The summer is unusually hot, and sales far exceed expectations. A tornado destroys the roof of the pop stick manufacturing plant at the beginning of August, and Poppy is out of business for three months. Based on the eight months of actual figures available, Poppy’s projected annual net income and continuing operations expenses for the year are $200,000. The loss for the three affected months is $50,000. The coinsurance penalty is calculated as follows:

1. Projected annual sales

$200,000

2. Coinsurance percentage

X .50

3. Required amount of insurance

= $100,000

4. Insured Limit divided by required limit

$80,000 / $100,000

5. Penalty for underinsurance

= .80

6. Actual loss amount

$50,000

7. Penalty factor (Step 3)

X .80

8. Amount paid

= $40,000

In this example, Poppy increased the business income limit to match estimated sales but still faced a penalty because even the most accurate estimates do not guarantee the coinsurance penalty can be avoided. ISO identified this issue and developed three alternative coinsurance options within the business income coverage forms, offered as Optional Coverages.

MAXIMUM PERIOD OF INDEMNITY

This option removes the coinsurance requirement by allowing the named insured to choose a specific insurance limit. If a covered loss occurs, the insured receives payment for up to 120 days of the loss or the insurance limit, whichever is less.

Example: Poppy’s Pop Sticks selects the Maximum Period of Indemnity option. He selects a limit by dividing his projected net income and continuing operating expense amount by 365 days, then multiplying the result by 120 days. This results in a limit of $52,603.

Alternatively, he could choose the months with the highest sales and insure the anticipated net income during those times. The sales were as follows:

·         $20,000 in June

·         $25,000 in July

·         $30,000 in August

·         $20,000 in September

The sales totaled $95,000. Poppy could select a limit of $95,000 since loss payments cease once this limit is reached or after 120 days, whichever comes first.

This option has a substantial rating surcharge but is a good choice when downtime is limited and predictable. It is activated when there is an entry in the box next to 'Maximum Period of Indemnity' on the declarations.

MONTHLY LIMIT OF INDEMNITY

This option removes the coinsurance requirement, allowing the named insured to choose the business income limit in increments of 1/3, 1/4, or 1/6, with payments made every 30 days. The payout continues every thirty days until the entire limit is exhausted or the restoration period ends, whichever occurs first.

Example: This option requires Poppy to know the maximum duration he might be unable to operate and the highest amount needed within any 30-day span. He estimates he can restore operations within four months, with August being his most profitable month. If he selects the 1/4 option and stays with his key months—June, July, and August—the limit is $75,000. The payment for August's loss will be as follows:

Period

Loss amount

Limit available

Amount paid

First 30 days

$30,000

$75,000 multiplied by 1/4 or .25 (25%) = $18,750

$18,750

Second 30 days

$15,000

$75,000 multiplied by 1/4 or .25 (25%) = $18,750

$15,000

Third 30 days

$10,000

$75,000 multiplied by 1/4 or .25 (25%) = $18,750

$10,000

Fourth 30 days

Poppy is adequately insured if the loss to the manufacturing plant occurs in any month except August. However, because of the timing of the loss, he cannot recover the full amount, as the chosen monthly limit was too low to cover the actual loss. If Poppy’s loss persists for more than 4 months, the insurance policy remains active until either the business resumes or the coverage limit is exhausted, whichever occurs first. The 1/4 recovery limitation does not restrict coverage to a four-month period.

This option is subject to a rating surcharge but is an excellent selection when the month with the largest loss can be identified and a limit and recovery basis selected to cover it. This option is triggered when the box next to Monthly Limit of Indemnity is checked on the declarations.

BUSINESS INCOME AGREED VALUE

This option eliminates the coinsurance condition for 12 months or until the policy's end date. It is triggered when the most recent Business Income Report/Worksheet is entered below the Agreed Value Optional Coverage on the declarations. This is subject to the insured submitting a Business Income Report/Worksheet at policy inception, whenever the business income insurance limit is adjusted, and at each 12-month anniversary. Both parties—insured and insurer—must agree on the appropriate insurance limit based on the Business Income Report/Worksheet.

The estimated value on the worksheet should be multiplied by the coinsurance percentage. The chosen insurance limit must be at least equal to the estimated value and must be listed on the declarations, including the coinsurance percentage. The coinsurance percentage applies if the insured breaches any provision of this optional coverage.

Example: Poppy’s Pop Sticks always completes the Business Income Report/Worksheet on time. Poppy submits the worksheet to the insurance company, and both parties agree to the $80,000 limit; as a result, coinsurance is suspended. The $50,000 loss that occurred in August is paid in full.

 A penalty similar to a coinsurance penalty is applied if the insured limit is lower than the agreed amount. The limit is divided by the agreed value, and the resulting ratio is multiplied by the actual loss.

This option incurs a 10% rating surcharge and requires the annual completion of the Business Income Report/Worksheet. Due to the challenge in estimating revenues, it may be the best choice for many insureds.

UNDERWRITING

The insurance company's profitability depends on providing coverage with appropriate insurance to value. This enables the "law of large numbers" and statistics to function more accurately and efficiently.

While the first two options above encourage the named insured not to insure to value, significant rate surcharges compensate for the premium shortfall caused by inadequate limits and serve as stabilizing or leveling devices.

The third option places a greater burden on the underwriter. The named insured submits a worksheet based on actual figures and then estimates the corresponding figures for the upcoming year. The underwriter insures based on the projected figures for the upcoming year and must be aware of general economic trends, especially within the specific industry involved. It is also important to review worksheets from previous years to determine if the named insured tends to make accurate estimates.

Furthermore, the obligation to submit a worksheet at least once a year or whenever the limit changes should never be waived.
