Use this form to create an allocation basis rule. An allocation rule can have a reference to an allocation basis rule, which defines how and in what proportion the source amounts are distributed to the various destination lines when the allocation rule has a Basis allocation method. An allocation basis rule can be used with many allocation rules.

Examples of basis allocation include the following:

  • Allocation based on square footage – The cost of utilities expense is shared across all departments, based on the square footage of each department in relation to the total square footage of all departments.

  • Allocation based on workers – The cost of renting office space is shared across all departments, based on the number of workers who work in each department.

  • Allocation based on revenue dollars – The cost of corporate advertising expense is shared across all departments, based on each department’s sales in proportion to the total revenue.

The following tables provide descriptions for the controls in this form.
