What makes a package a package? At minimum: the Common Policy Declarations, the Common Policy Conditions and at least two coverage parts. Adding more locations, forms or endorsements inside one coverage part does not create a second part.

Coverage parts a CPP can combine include commercial property, commercial general liability, commercial crime, commercial inland marine, commercial auto, equipment breakdown and farm. Workers' compensation is written on its own separate policy, so it is not a CPP coverage part.

Why buy a package? - One policy with a single renewal date, so administration is simpler - Fewer gaps and overlaps than separately purchased policies - A possible package credit (often called the package modification factor), because writing several lines together lowers the insurer's handling costs and spreads the risk A package does not take away the insurer's right to audit, and each coverage part keeps its own limits.

Any of these coverages can also be written alone on a "monoline" basis. A monoline policy still has declarations and common conditions, but with only one coverage part it is not a package and earns no package credit.
