GGP owns big malls in Towson, Columbia, White Marsh, Owings Mills and Baltimore, not to mention huge commercial & residential assets in Columbia. Here is a recent column on General Growth's problems through a Baltimore lens. From the WSJ:

Ailing mall owner General Growth Properties Inc. warned Monday in a government filing that its failure to refinance or extend $1 billion in debt due this month could trigger default on billions of dollars in debt and its ability to continue operations would be in "substantial doubt."

One of the nation's largest shopping mall owners, General Growth made the warning in a quarterly filing with the U.S. Securities and Exchange Commission. The company, based in Chicago, faces an additional $3.07 billion in debt coming due next year.

If General Growth cannot raise additional capital to pay off that debt or extend its payment deadlines, it would need to take additional steps to acquire needed funds, "including seeking legal protection from our creditors," according to the SEC filing.
