American Airlines Arena and American Airlines Center
Home of: The Miami Heat (NBA) and Dallas Mavericks (NBA), respectively
Cost of naming rights: More than $8 million a year combined

Spending nearly $9 million a year on arena naming rights alone is just fine when your company's name is on both buildings hosting the NBA Finals, as American's was in 2006 and last year.

When your name and logo is stamped all over those buildings just as your company is entering bankruptcy, cutting more than 10,000 jobs and restructuring pensions, it's somewhat less flattering. A year removed from an all-American final between the Heat and the Mavericks, American Airlines has entered bankruptcy, changed chief executives and is mulling a merger with US Airways ( LCC).

The arena naming rights are secure for now, but if the Heat continue on to the NBA Finals this year, it may be the last time American Airlines gets them there.
