Yes, that is what it "looks" like. But as a stand-alone document it's virtually meaningless. I don't know why dismal is putting himself through all those contortions to assure us (without any knowledge) that the $103m deduction was a straightforward loss such as you or I would report. The only salient facts it brings to light are that he had close to $150m in income in 2005 prior to deductions, 40-something million after deductions, and absent the AMT he would have only paid some $5m in taxes vs the $38m he actually paid. And to quell dismal's screaming, the $38m he paid included (and is mostly comprised of) taxes on the 103m he deducted per the AMT schedule.
Tax of $5M on taxable income of $31M is a low enough rate to suggest that a large fraction of his taxable income came from the capital gains.
Like that house he sold to the Russian oligarch, for twice what he paid, in a declining real estate market? Never mind. Nothing to see there...
