Reportable Segments
Our business is comprised of two business lines: (1) Drilling Services and (2) Rental Tools Services. Effective with the first quarter of 2015, we aligned our reportable segments with our two core business lines and our current internal organizational structure. We report our Rental Tools Services business as one reportable segment (Rental Tools) and report our Drilling Services business as two reportable segments: (1) U.S. (Lower 48) Drilling and (2) International & Alaska Drilling. We eliminate inter-segment revenue and expenses.
The following table represents the results of operations by reportable segment:
