From the WashingtonPost.com:
 
You don't often get to use "Time  Warner" and "hot stock" in the same sentence, given the  company's horrible investment performance over the years.
 
But Time Warner's pending deal to unburden  itself of AOL by dumping the ailing firm onto its shareholders is one  of those times, thanks to an insight I got from tax guru Bob Willens  of Robert Willens LLC. Willens, who lives and breathes (and probably  dreams about) the tax code, says that Time Warner's plan to distribute  AOL stock to its shareholders in a tax-free transaction is benefiting  from a little-noticed change last year in the rules governing "hot  stocks."
In this case, "hot stock" doesn't  mean shares with a rapidly rising price; it means shares that can trigger  a tax liability.
The "hot stock" here would  be Google's 5 percent stake in AOL. Time Warner sold those shares to  Google in 2005, and plans to buy them back by the end of this year,  then distribute them (along with the other 95 percent of AOL) to Time  Warner shareholders in a tax-free deal.
Without last year's change, Willens says,  the Google stake in AOL would have been a "hot stock" to both  Time Warner and its shareholders because Time Warner would have been  distributing the stock to its holders within five years after buying  it from Google.
How much in tax savings are we talking  about? Call it $200 million or so. The exact amount depends on the market  value of AOL stock when Time Warner distributes it. Should AOL be valued  at $5.5 billion, the value that Google placed on AOL in February, the  "hot stock" rule change would save Time Warner and its shareholders  from having to report $275 million each in taxable income. (I'm assuming  that Time Warner's cost of AOL for tax purposes is close to zero.) At  federal, state and local tax rates totaling 40 percent, Time Warner  and its shareholders each save about $110 million.
 
Willens says the "hot stock"  rule was changed last December when the Treasury tweaked the appropriate  regulations. A Time Warner spokesman said the company played no role  in the change. Spokesmen for the Treasury and Google declined to comment.
 
Under the previous rules, there would  have been a "hot stock" liability because Google decided to  invoke its right under the AOL stock-purchase agreement to sell back  its AOL stake to Time Warner. The price is currently being negotiated.
 
I suspect that taxes play a big role  in Google's decision to sell. If Google, which paid $1 billion for its  AOL stake, sells the stake for the $274 million at which it's now carried  on its books, it gets a $726 million tax loss. That would reduce its  income-tax bill by about $290 million.
Time Warner and its shareholders avoid  taxes, perfectly legally, and Google gets to save some taxes, also perfectly  legally. All other taxpayers, in effect, pick up the tab for those savings.
 
'Twas ever thus, when it comes to big-time  dealmaking. And 'twill always be thus.
