Taxpayer A manufactures widgets. Although A's manufacturing facility operates 24 hours each day in three shifts, A only operates its stamping machine during one shift each day. Because A only operates its stamping machine during certain shifts, A's stamping machine is not considered temporarily idle during the two shifts that it is not operated.
Taxpayer B owns and operates a manufacturing facility. B closes its manufacturing facility for two weeks to retool its assembly line. B's manufacturing facility is considered temporarily idle during this two-week period.
(i) Taxpayer E has the following five departments: the Assembling Department, the Painting Department, and the Finishing Department (production departments), and the Personnel Department and the Data Processing Department (mixed service departments). E allocates the Personnel Department's costs on the basis of total payroll costs and the Data Processing Department's costs on the basis of data processing hours.
(ii) Under a direct reallocation method, E allocates the Personnel Department's costs directly to its Assembling, Painting, and Finishing Department, and not to its Data Processing department.
| Department | Total dept. costs | Amount of payroll costs | Allocation ratio | Amount allocated |
|---|---|---|---|---|
| Personnel | $500,000 | $50,000 | <$500,000> | |
| Data Proc'g | 250,000 | 15,000 | ||
| Assembling | 250,000 | 15,000 | 15,000/285,000 | 26,315 |
| Painting | 1,000,000 | 90,000 | 90,000/285,000 | 157,895 |
| Finishing | 2,000,000 | 180,000 | 180,000/285,000 | 315,790 |
| Total | $4,000,000 | $350,000 |
(iii) After E allocates the Personnel Department's costs, E then allocates the costs of its Data Processing Department in the same manner.
| Department | Total dept. cost after initial allocation | Total data proc. hours | Allocation ratio | Amount allocated | Total dept. cost after final allocation |
|---|---|---|---|---|---|
| Personnel | 0 | 2,000 | 0 | ||
| Data Proc'g | $250,000 | <$250,000> | |||
| Assembling | 276,315 | 2,000 | 2,000/10,000 | 50,000 | $326,315 |
| Painting | 1,157,895 | 0 | 0/10,000 | 0 | 1,157,895 |
| Finishing | 2,315,790 | 8,000 | 8,000/10,000 | 200,000 | 2,515,790 |
| Total | $4,000,000 | 12,000 | $4,000,000 |
(i) Taxpayer F has the following five departments: the Manufacturing Department (a production department), the Marketing Department and the Finance Department (departments that incur only deductible service costs), the Personnel Department and the Data Processing Department (mixed service departments). F uses a step-allocation method and allocates the Personnel Department's costs on the basis of total payroll costs and the Data Processing Department's costs on the basis of data processing hours. F's Personnel Department benefits all four of F's other departments, while its Data Processing Department benefits only three departments. Because F's Personnel Department benefits the greatest number of other departments, F first allocates its Personnel Department's costs to its Manufacturing, Marketing, Finance and Data Processing departments, as follows:
| Department | Total cost of dept. | Total payroll costs | Allocation ratio | Amount allocated |
|---|---|---|---|---|
| Personnel | $500,000 | $50,000 | <$500,000> | |
| Data Proc'g | 250,000 | 15,000 | 15,000/300,000 | 25,000 |
| Finance | 250,000 | 15,000 | 15,000/300,000 | 25,000 |
| Marketing | 1,000,000 | 90,000 | 90,000/300,000 | 150,000 |
| Manufac'g | 2,000,000 | 180,000 | 180,000/300,000 | 300,000 |
| 4,000,000 | 350,000 |
(ii) Under a step-allocation method, the denominator of F's allocation ratio includes the payroll costs of its Manufacturing, Marketing, Finance, and Data Processing departments.
(iii) Next, F allocates the costs of its Data Processing Department on the basis of data processing hours. Because the costs incurred by F's Personnel Department have already been allocated, no allocation is made to the Personnel Department.
| Department | Total dept. cost after initial allocation | Total data proc. hours | Allocation | ||
|---|---|---|---|---|---|
| ratio | |||||
| Personnel | $0 | 2,000 | $0 | ||
| Data Proc'g | 275,000 | <$275,000> | 0 | ||
| Finance | 275,000 | 2,000 | 2,000/10,000 | 55,000 | 330,000 |
| Marketing | 1,150,000 | 0 | 0/10,000 | 0 | 1,150,000 |
| Manufac'g | 2,300,000 | 8,000 | 8,000/10,000 | 220,000 | 2,520,000 |
| 4,000,000 | 12,000 | 4,000,000 |
(iv) Under the second step of F's step-allocation method, the denominator of F's allocation ratio includes the data processing hours of its Manufacturing, Marketing, and Finance Departments, but does not include the data processing hours of its Personnel Department (the other mixed service department) because the costs of that department have previously been allocated.
Y is a manufacturer of automobiles. During the taxable year Y produces numerous substantially identical dies and molds using standardized designs and assembly line techniques. The dies and molds have a 3-year applicable recovery period for purposes of section 168(c). Y uses the dies and molds to produce or process particular automobile components and does not hold them for sale. The dies and molds are produced on a routine and repetitive basis in the ordinary course of Y's business for purposes of this paragraph because the dies and molds are both mass-produced and have a recovery period of not longer than 3 years.
Z is an electric utility that regularly manufactures and installs identical poles that are used in transmitting and distributing electricity. The poles have a 20-year applicable recovery period for purposes of section 168(c). The poles are not produced on a routine and repetitive basis in the ordinary course of Z's business for purposes of this paragraph because the poles have an applicable recovery period that is longer than 3 years.
