Chicago-based Equity Residential has been given an extension until April 19 to bid on the second part of Bank of America Corp. and Barclays' stake in Denver-based Archstone. The announcement leaves analysts wondering what the extension could signify.

Last week’s announcement by Chicago-based Equity Residential (EQR) that it entered into an agreement to spend $1.325 billion in cash for a 26.5 percent ownership interest in Denver-based Archstone, which owns 48,922 units and has 1,332 units under construction, took some people by surprise.
According to a geographic exposure study recently conducted by Charlottesville, Va.-based SNL Financial, since 2007, Archstone has decreased its overall asset exposure in Virginia and California, while increasing its asset bulk in Georgia, Florida, and Texas.

No matter what road you're on in life or in business, a diverse mix can make sure you're around to succeed.
