The company controller, Barry Melrose, has asked for your help in interpreting the authoritative accounting literature that addresses the recognition and measurement of impairment losses for property, plant, and equipment and intangible assets. “We have a significant amount of goodwill on our books from last year's acquisition of Churchill Corporation. Also, I think we may have a problem with the assets of some of our factories out West. And one of our divisions is currently considering disposing of a large group of depreciable assets.”
Your task as assistant controller is to research the issue.

Required:
1. Obtain the relevant authoritative literature on accounting for the impairment of property, plant, and equipment and intangible assets using the FASB's Codification Research System. You might gain access at the FASB website (www.fasb.org). Cite the reference locations regarding impairment of property, plant, and equipment and intangible assets.
2. When should property, plant, and equipment and intangible assets be tested for impairment?
3. Explain the process for measuring an impairment loss for property, plant, and equipment and intangible assets to be held and used.
4. What are the specific criteria that must be met for an asset or asset group to be classified as held-for-sale? What is the specific citation reference from the FASB's Codification Research System that contains these criteria?
5. Explain the process for measuring an impairment loss for property, plant, and equipment and intangible assets classified as held-for-sale.
