Redline Publishers, Inc. produces various manuals ranging from computer software instructional booklets to manuals explaining the installation and use of large pieces of industrial equipment. At the end of 2013, the company's balance sheet reported total assets of $62 million and total liabilities of $40 million. The income statement for 2013 reported net income of $1.1 million, which represents an approximate 3% increase from the prior year. The company's effective income tax rate is 30%.
Near the end of 2013, a variety of expenditures were made to overhaul the company's manufacturing equipment. None of these expenditures exceeded $750, the materiality threshold the company has set for the capitalization of any such expenditure. Even though the overhauls extended the service life of the equipment, the expenditures were expensed, not capitalized.
John Henderson, the company's controller, is worried about the treatment of the overhaul expenditures. Even though no individual expenditure exceeded the $750 materiality threshold, total expenditures were $70,000.

Required:
Should the overhaul expenditures be capitalized or expensed?
