Segment Reporting [Abstract]

Business Segment Information

Business Segment Information

The Company classifies its businesses into the following four reportable segments based on industry and market focus: Climate Solutions, Residential Solutions, Industrial Technologies and Security Technologies.

Segment operating income is the measure of profit and loss that the Company's chief operating decision maker uses to evaluate the financial performance of the business and as the basis for performance reviews, compensation and resource allocation. For these reasons, the Company believes that Segment operating income represents the most relevant measure of segment profit and loss. The Company may exclude certain charges or gains from Operating income to arrive at a Segment operating income that is a more meaningful measure of profit and loss upon which to base its operating decisions.

A summary of operations by reportable segment for the three months ended March 31 was as follows:

These amounts have been excluded from Segment operating income within the Climate Solutions segment as management excludes these charges from Operating income when making operating decisions about the business.
