UIL Holdings has three reporting segments:  Electric Distribution, Electric Transmission and Gas Distribution.  Revenues from inter-segment transactions are not material.  All of UIL Holdings' revenues are derived in the United States.  The following measures of segment profit and loss are utilized by management to make decisions about allocating resources to the segments and assessing performance.  The following table reconciles certain segment information with that provided in UIL Holdings' Consolidated Financial Statements.  In the table, distribution includes all electric utility revenue and expenses except for transmission, which is provided in a separate column.  “Other” includes the information for the remainder of UIL Holdings' non-utility activities and unallocated corporate costs, including minority interest investments and administrative costs.
