Business Segment Information

BUSINESS SEGMENT INFORMATION

We are a global oilfield provider of engineered services and products, primarily to the offshore oil and gas industry, with a focus on deepwater applications. Through the use of our applied technology expertise, we also serve the defense, aerospace and commercial theme park industries. Our Oilfield business consists of Remotely Operated Vehicles ("ROVs"), Subsea Products, Subsea Projects and Asset Integrity. Our ROV segment provides submersible vehicles operated from the surface to support offshore oil and gas exploration, development and production activities. Our Subsea Products segment supplies a variety of specialty subsea hardware and related services. Our Subsea Projects segment provides multiservice subsea support vessels and oilfield diving and support vessel operations, primarily for inspection, maintenance and repair and installation activities. Since April 2015, we have also provided survey, autonomous underwater vehicle ("AUV") and satellite-positioning services. Our Asset Integrity segment provides asset integrity management and assessment services and nondestructive testing and inspection. Our Advanced Technologies business provides project management, engineering services and equipment for applications in non-oilfield markets. Unallocated Expenses are those not associated with a specific business segment. These consist of expenses related to our incentive and deferred compensation plans, including restricted stock and bonuses, as well as other general expenses, including corporate administrative expenses.

There are no differences in the basis of segmentation or in the basis of measurement of segment profit or loss from those used in our consolidated financial statements for the year ended December 31, 2015.

The table that follows presents Revenue and Income from Operations by business segment for each of the periods indicated.

We determine income from operations for each business segment before interest income or expense, other income (expense) and provision for income taxes. We do not consider an allocation of these items to be practical. Our equity in earnings (losses) of unconsolidated affiliates is part of our Subsea Projects segment.
