The opposition to Section 382 is part of a broader ideological battle over how the tax code deals with a company's losses. Some conservative economists argue that not only should a firm be able to use losses to offset gains, but that in a year when a company only loses money, it should be entitled to a cash refund from the government.
During the current Bush administration, senior officials considered ways to implement some version of the policy. A Treasury paper in December 2007 -- issued under the names of Eric Solomon, the top tax policy official in the department, and his deputy, Robert Carroll -- criticized limits on the use of losses and suggested that they be relaxed. A logical extension of that argument would be an overhaul of 382, according to Carroll, who left his position as deputy assistant secretary in the Treasury's office of tax policy earlier this year.
Yet lobbyists trying to modify the obscure section found that they could get no traction in Congress or with the Treasury.
"It's really been the third rail of tax policy to touch 382," said Kevin A. Hassett, director of economic policy studies at the American Enterprise Institute.
As turmoil swept financial markets, banking officials stepped up their efforts to change the law.
Senior executives from the banking industry told top Treasury officials at the beginning of the year that Section 382 was bad for businesses because it was preventing mergers, according to Scott E. Talbott, senior vice president for the Financial Services Roundtable, which lobbies for some of the country's largest financial institutions. He declined to identify the executives and said the discussions were not a concerted lobbying effort. Lobbyists for the biotechnology industry also raised concerns about the provision at an April meeting with Solomon, the assistant secretary for tax policy, according to talking points prepared for the session.
DeSouza, the Treasury spokesman, said department officials in August began internal discussions about the tax change. "We received absolutely no requests from any bank or financial institution to do this," he said.
Although the department's action was prompted by spreading troubles in the financial markets, Carroll said, it was consistent with what the Treasury had deemed in the December report to be good tax policy.
The notice was released on a momentous day in the banking industry. It not only came 24 hours after the House of Representatives initially defeated the bailout bill, but also one day after Wachovia agreed to be acquired by Citigroup in a government-brokered deal.
The Treasury notice suddenly made it much more attractive to acquire distressed banks, and Wells Fargo, which had been an earlier suitor for Wachovia, made a new and ultimately successful play to take it over.
The Jones Day law firm said the tax change, which some analysts soon dubbed "the Wells Fargo Ruling," could be worth about $25 billion for Wells Fargo. Wells Fargo declined to comment for this article.
The tax world, meanwhile, was rushing to figure out the full impact of the notice and who was responsible for the change.
Jones Day released a widely circulated commentary that concluded that the change could cost taxpayers about $140 billion. Robert L. Willens, a prominent corporate tax expert in New York City, said the price is more likely to be $105 billion to $110 billion.
Over the next month, two more bank mergers took place with the benefit of the new tax guidance. PNC, which took over National City, saved about $5.1 billion from the modification, about the total amount that it spent to acquire the bank, Willens said. Banco Santander, which took over Sovereign Bancorp, netted an extra $2 billion because of the change, he said. A spokesman for PNC said Willens's estimate was too high but declined to provide an alternate one; Santander declined to comment.
Attorneys representing banks celebrated the notice. The week after it was issued, former Treasury officials now in private practice met with Solomon, the department's top tax policy official. They asked him to relax the limitations on banks even further, so that foreign banks could benefit from the tax break, too.
Congress Looks for AnswersNo one in the Treasury informed the tax-writing committees of Congress about this move, which could reduce revenue by tens of billions of dollars. Legislators learned about the notice only days later.
