A Georgia county has been ordered to pay more than more than $4 million in damages and attorney fees to a billboard company as part of its ongoing fight to keep billboards out of Atlanta's northern suburbs.

The Atlanta Journal-Constitution reports that the verdict is the latest blow to Fulton County in its long-running legal battle against billboard companies.

A U.S. District Court in Atlanta jury last month awarded the $3.97 million in damages to KH Outdoor, which sued the county in 2003. Last week, a federal judge ordered the county to pay $477,156 in attorneys' fees and expenses to the company's lawyers.

Adam Webb, a lawyer for the billboard company, declined to comment. Fulton County Attorney David Ware said an appeal by the county "remains a viable option."

New York's attorney general is investigating tax strategies of some of the nation's largest private equity firms, including Bain Capital, founded by Republican presidential nominee Mitt Romney, an official familiar with the probe said Sunday.

Attorney General Eric Schneiderman is examining whether the firms have abused a tax strategy to avoid paying hundreds of millions of dollars in taxes, said the official, who spoke on the condition of anonymity because of the sensitivity of the probe. The practice involves converting some fees collected for managing accounts into fund investments, resulting in a lower tax rate.

Some tax experts who spoke to The New York Times, which first reported the investigation Sunday, believed the strategy was potentially illegal, though other experts said it was commonplace and proper.

The Democratic attorney general sent subpoenas to more than a dozen firms, including Kohlberg Kravis Roberts & Company, TPG Capital, Sun Capital Partners, Apollo Global Management, Silver Lake Partners and Bain Capital, according to the official.
