Note 17 ― Segment Information

See Note 1 for a description of the Company’s reporting segments.

In the Company’s segment disclosures, we present “operating revenues,” defined as total revenues excluding realized investment results. Beginning in 2018, realized investment results from the Company's equity method joint ventures in the Global Supplemental Benefits segment are also excluded due to the potential increased volatility in investment results after adopting ASU 2016-01. Investment gains or losses are managed based on factors largely unrelated to the underlying business purpose of each segment and are not indicative of the underlying performance of the Company’s core business operations, so they are excluded from operating revenues.

The Company uses “adjusted income (loss) from operations” as its principal financial measure of segment operating performance because management believes it best reflects the underlying results of core business operations and permits analysis of trends in underlying revenue, expenses and profitability. Adjusted income from operations is defined as shareholders’ net income (loss) excluding after-tax realized investment gains and losses, amortization of other acquired intangible assets and special items. Income or expense amounts that are excluded from adjusted income from operations because they are not indicative of underlying performance or the responsibility of operating segment management include:

Realized investment results, including changes in market values of certain financial instruments between balance sheet dates, as well as gains and losses associated with invested asset sales. As discussed above, beginning in 2018, realized investment results from the Company's equity method joint ventures in the Global Supplemental Benefits segment are also excluded.
Amortization of other intangible assets related to costs incurred for acquisitions
Special items, if any, that management believes are not representative of the underlying results of operations due to the nature or size of these matters. Further context about these items is provided in the footnotes listed in the table below.
