Q11. Direct method using estimated costs, benchmarking
Devon Ltd allocates support department costs using the direct method and estimated costs. The support department costs are budgeted at $88 000 for department A, $63 000 for department B, and $40 000 for department C. These costs are allocated using the proportion of total cost the firm would pay to an outside service provider.

(b) Could Devon Ltd use the cost of purchasing outside as an efficiency benchmark for the cost of both the support departments and the user departments? List several advantages and disadvantages of this approach.
Q12. Reciprocal method
The Brown and Brinkley Brokerage firm is organised into two major sales divisions: institutional clients and retail clients. The firm also has two support departments: research and administration. The research department's costs are allocated to the other departments based on a log of hours spent on tasks for each user. The administration department's costs are allocated based on the number of employees in each department.
Records are available for last period as follows.

Q13. Step-down, direct, and reciprocal methods; accuracy of allocation
Software Plus Ltd produces flight and driving simulations and games for personal computers. The company's president has a complaint about the accounting for support department costs. He points to the following table describing the use of various support departments in the company and says, 'According to this table, every department receives services from all the support departments. But I understand that only some of the support departments are bearing costs from the other support departments. Why is that?'
