Example 1: The taxpayer uses some of its employees in the construction of a storage building which, upon completion, is used in the regular course of the taxpayer's trade or business. The wages paid to those employees are treated as a capital expenditure by the taxpayer. The amount of those wages is included in the payroll factor.
Example 2: The taxpayer owns various securities that it holds as an investment separate and apart from its trade or business. The management of the taxpayer's investment portfolio is the only duty of Mr. X, an employee. The salary paid to Mr. X is excluded from the payroll factor.
