The Special Causes of Loss form is just that, special. It provides coverage for risks of direct physical loss unless, of course, they are excluded or limited. Unlike the Basic and Broad forms, which only cover what’s listed, the Special form covers everything except what’s listed in the called-out exclusions, limitations, and conditions.
commercial property than the Basic or Broad form provides.
A couple of items to note:
When rating a policy with the Special form, both class-rated and specifically-rated properties are eligible. The amount of insurance and the coinsurance percentage must be the same for each cause of loss rated.
Property in offices may be written as a separate item under Special Causes of Loss, and Basic or Broad Causes of Loss forms can be used for the remaining property.
Like on the Broad Causes of Loss form, the Special Causes of Loss form requires that coinsurance be at least 80% for property damage and 50% for time-element coverages. Be aware that certain risks cannot be covered under the Special form (Rule 72.C.). These include:
Group I Causes of Loss
Group II Causes of Loss
Special Causes of Loss
Basic Group I (BGI) and Basic Group II (BGII) loss costs are determined in the same way as a Basic form policy, regardless of whether the risk is class or specifically rated.
Here’s what the Special form loss costs might look like using the LOI rating method:
Building coverage
Loss cost: .066 (includes theft coverage) – Current loss cost (CF 2020-RLA1 approved effective 09/01/2021).
Loss cost: .056 (includes theft coverage) – Prior loss cost (CF-2014-RLA1 approved effective 06/12/2015).
To exclude theft from building coverage, apply a factor of .88 to the building rate.

BGI and BGII loss costs: When rating these for a Special form policy, apply the same rate factors in the same order as for a Basic form policy.
Special form loss costs: Apply applicable rate factors in the following order:
Remember to apply additive factors before applying multiplicative factors unless a rule states otherwise.
The “formula” to rate a policy with Special Causes of Loss without factors or charges dictated by individual rules — using (LOI) methodology would look like this:
It is important to note that Territory and Protection Class multipliers do not apply to Group II.
Note that the Protection Class Multiplier does not apply to Special Causes of Loss.
You will find the complete Causes of Loss — Special Form Rule (Rule 72) in Division Five of the Commercial Lines Manual.
