During the current year, Black Corporation incurred the following expenditures which should be recorded either as operating expenses or as intangible assets:
a. Expenditures were made for the training of new employees. The average employee remains with the company for five years, but is trained for a new position every two years.
b. Black purchased a controlling interest in a vinyl flooring company. The expenditure resulted in the recording of a significant amount of goodwill. Black expects to earn above-average returns on this investment indefinitely.
c. Black incurred large amounts of research and development costs in developing a dirt-resistant carpet fiber. The company expects that the fiber will be patented and that sales of the resulting products will contribute to revenue for at least 25 years. The legal life of the patent, however, will be only 20 years.
d. Black made an expenditure to acquire the patent on a popular carpet cleaner. The patent had a remaining legal life of 14 years, but Black expects to produce and sell the product for only six more years.
e. Black spent a large amount to sponsor the televising of the Olympic Games. Black's intent was to make television viewers more aware of the company's name and its product lines.
