The Vanishing Shopping Mall

This story is about 10 days old, but I just stumbled upon it. The statistic in here that caught my eye is the claim that 400 malls have shut in the past two years. Is this true? I have not heard this figure reported anywhere else and the article doesn't source it.

More than 400 of the 2,000 largest malls in the U.S. have closed in the past two years. The last new major mall in the U.S. opened in 2006, and only one big mall is scheduled to open this year—the troubled Xanadu mega-mall in Rutherford, N.J. (See below.) With some 150,000 retail stores projected to fail in the U.S. this year, more mall closings are imminent. Mall mainstays such as Mervyn's department stores, Linens 'n Things, and KB Toys have already disappeared into bankruptcy, and mall vacancy rates topped 7 percent last year, the highest level since 2001. “It's an absolute disaster,” says Howard Davidowitz, an investment banker specializing in retailers. “What a mall represents is discretionary spending, and discretionary spending is in a depression.”
