Kraft (KRFT) and Heinz Agree to Merge

Combined company would be third-largest food and beverage company.

The combined company's brands include Kraft, Heinz, Oscar Mayer deli meats, Planters nuts and Maxwell House Coffee.

But these are challenging times for packaged food companies. Because of changing consumer tastes many well-known food brands are struggling with declining sales. Kraft’s profit last year fell more than 60 percent.

Both companies' boards have unanimously approved the deal, which is targeted to close in the second half of the year. It still needs approval from Kraft shareholders.
