CEO Sam Zell said the company ran into a “perfect storm — a precipitous decline in revenue and a tough economy coupled with a credit crisis that makes it extremely difficult to support our debt.”

The Cubs and Wrigley Field weren’t included in the Chapter 11 filing, and the Cubs promptly released a statement saying, “The Chicago Cubs are not included in Tribune’s restructuring and the business and baseball operations of the Cubs continue independent of Tribune’s decision to restructure its debt.

We remain exclusively focused on our singular goal of securing a World Championship for our fans and the city of Chicago.”
