The U.S. parent company of Dunkin Donuts and Baskin-Robbins said Monday its initial public offering could raise $400 million. Dunkin\' Brand filed an amended S-1 form with the U.S. Securities and Exchange Commission seeking to sell more than 22 million shares. Shares are expected to go for $16 to $18. The company would wind up with 126 million common shares and The Street said the paperwork crunches down to a market value of more than $2 billion. Dunkin\' Brands is seen as an attractive bet by some analysts due to its heavy cash flow and strong presence in the New York and New England areas. The company has a worldwide presence with locations in 57 countries. The Street said the downside is a lag in revenues compared to its major competitor, Starbucks, and its franchise business model compared to Starbucks\' outright ownership of its stores.
