Segment Information

Segment Information

Effective October 1, 2015, the Company reorganized the reportable segments within its Building Efficiency business to align with its new management reporting structure and business activities. Prior to this reorganization, Building Efficiency was comprised of three reportable segments for financial reporting purposes: North America Systems and Service, Asia and Other. As a result of this change, Building Efficiency is now comprised of four reportable segments for financial reporting purposes: Systems and Service North America, Products North America, Asia and Rest of World. Historical information has been revised to reflect the new Building Efficiency reportable segments.

A summary of the significant Building Efficiency reportable segment changes is as follows:

• The North America Unitary Products business, Air Distribution Technologies business and refrigeration systems business, as well as heating, ventilating and air conditioning (HVAC) products installed for Navy and Marine customers, previously included in the "Other" segment, are now part of a new reportable segment named "Products North America."

• The building controls parts business in North America, previously included in the "North America Systems and Service" segment, is now part of the "Products North America" segment.

• The remainder of the "Other" segment has been renamed "Rest of World."

• Certain reportable segment allocation methodologies have been refined for centralized costs such as engineering and headquarters.

ASC 280, "Segment Reporting," establishes the standards for reporting information about segments in financial statements. In applying the criteria set forth in ASC 280, the Company has determined that it has seven reportable segments for financial reporting purposes. The Company’s seven reportable segments are presented in the context of its three primary businesses – Building Efficiency, Automotive Experience and Power Solutions.

Building Efficiency

Building Efficiency designs, produces, markets and installs HVAC and control systems that monitor, automate and integrate critical building segment equipment and conditions including HVAC, fire-safety and security in commercial buildings and in various industrial applications.

The products and services include HVAC and controls systems, energy efficiency solutions and technical services, including inspection, scheduled maintenance, and repair and replacement of mechanical and control systems.

• Products North America designs and produces heating and air conditioning solutions for residential and light commercial applications, and also markets products and refrigeration systems to the replacement and new construction markets in the North American marketplace. Products North America also includes HVAC products installed for Navy and Marine customers globally.

• Interiors produces instrument panels, floor consoles and door panels.

Power Solutions

Management evaluates the performance of the segments based primarily on segment income, which represents income from continuing operations before income taxes and noncontrolling interests excluding net financing charges, significant restructuring and impairment costs, and net mark-to-market adjustments on pension and postretirement plans. General corporate and other overhead expenses are allocated to segments in determining segment income.
