If a business with $500K of tangible assets is purchase for $1M, there is $500K of excess value - or "goodwill" - that appears on the balance sheet of the buying company. My understanding is that private companies can amortize goodwill on a 10-year straight-line basis for tax purposes. But the accounting standards do not allow you to amortize goodwill - only take "impairments" - so in effect you have to maintain two sets of books for tax versus GAAP accounting. What parts of the above are incorrect?
How does the above change for a company that trades on the public stock markets? Are they also allowed to take the 10 years of tax deductions?
Does anyone reading this happen to know how the above is treated for an Australian company that trades on the Australian public stock markets?
