GENERAL DYNAMICS CORP | 2013 | FY | 3

BUSINESS GROUP INFORMATION
We operate in four business groups: Aerospace, Combat Systems, Marine Systems and Information Systems and Technology. We organize our business groups in accordance with the nature of products and services offered. These business groups derive their revenues from business aviation; combat vehicles, weapons systems and munitions; military and commercial shipbuilding and services; and communication and information technology systems and solutions, respectively. We measure each group’s profit based on operating earnings. As a result, we do not allocate net interest, other income and expense items, and income taxes to our business groups.
Summary financial information for each of our business groups follows:
