Segment Information

Our two reportable segments are i) general rentals and ii) trench, power and pump. The general rentals segment includes the rental of i) general construction and industrial equipment, such as backhoes, skid-steer loaders, forklifts, earthmoving equipment and material handling equipment, ii) aerial work platforms, such as boom lifts and scissor lifts and iii) general tools and light equipment, such as pressure washers, water pumps and power tools. The general rentals segment reflects the aggregation of 11 geographic regions—Carolinas, Gulf South, Industrial (which serves the geographic Gulf region and has a strong industrial presence), Mid-Atlantic, Mid Central, Midwest, Northeast, Pacific West, South, Southeast and Western Canada—and operates throughout the United States and Canada. We periodically review the size and geographic scope of our regions, and have occasionally reorganized the regions to create a more balanced and effective structure.

The trench, power and pump segment includes the rental of specialty construction products such as i) trench safety equipment, such as trench shields, aluminum hydraulic shoring systems, slide rails, crossing plates, construction lasers and line testing equipment for underground work, ii) power and HVAC equipment, such as portable diesel generators, electrical distribution equipment, and temperature control equipment and iii) pumps primarily used by energy and petrochemical customers. The trench, power and pump segment is comprised of the following regions, each of which primarily rents the corresponding equipment type described above: (i) the Trench Safety region, (ii) the Power and HVAC region, and (iii) the Pump Solutions region. The trench, power and pump segment’s customers include construction companies involved in infrastructure projects, municipalities and industrial companies. This segment operates throughout the United States and in Canada.

The following table presents the percentage of equipment rental revenue by equipment type for the years ended December 31, 2017, 2016 and 2015:



	Year Ended December 31,
	2017		2016		2015
Primarily rented by our general rentals segment:
General construction and industrial equipment	43	%	43	%	43	%
Aerial work platforms	32	%	32	%	32	%
General tools and light equipment	7	%	8	%	10	%
Primarily rented by our trench, power and pump segment:

These segments align our external segment reporting with how management evaluates business performance and allocates resources. We evaluate segment performance based on segment equipment rentals gross profit.

The accounting policies for our segments are the same as those described in the summary of significant accounting policies in note 2. Certain corporate costs, including those related to selling, finance, legal, risk management, human resources, corporate management and information technology systems, are deemed to be of an operating nature and are allocated to our segments based primarily on rental fleet size.
