Cowabunga Corp. had a highly profitable year 4, during which it purchased $1,000,000 in tangible personal property and elected to claim the highest depreciation expense allowed for tax purposes under § 179. In year 6, Cowabunga sells the tangible personal property, which now has an adjusted basis of $200,000 as a result of the heavy depreciation taken in years 4 and 5. Had only MACRS depreciation been taken on the property, its adjusted basis at the time of sale would have been $800,000. At a sales price of $930,000, how much of the $730,000 realized gain must be reported as ordinary gain for tax purposes?

a. $720,000

b. $600,000

c. $0

d. $730,000
