Note17 ― Segment Information

The Company's operating segments generally reflect groups of related products, but the International segment is generally based on geography. Beginning with the acquisition of HealthSpring in January 2012, the financial results of the former Health Care operating segment and this newly acquired Medicare operating segment have been aggregated as the Health Care reportable segment reflecting their similar economic characteristics, products and services, customers, distribution methods, operational processes and regulatory environment. Results of the recently acquired Great American Supplemental Benefits business are reported in the supplemental health, life and accident business included in the International segment. Other operating segments that do not require separate disclosure have been combined into Other Operations.

The Company measures the financial results of its segments using “segment earnings (loss)”, which is defined as shareholders' net income (loss) excluding after-tax realized investment gains and losses. As discussed in Note 2, in 2012, the Company adopted amended accounting guidance for deferred acquisition costs through retrospective adjustment of prior periods. See Note 2 for the effect of this amended guidance on previously reported segment revenue and earnings amounts.

Concentration of risk. For theCompany's International segment, South Korea is the single largest geographic market. South Korea generated 30% of the segment's revenues and 55% of the segment's earnings for the three months ended September 30, 2012. South Korea generated 29% of the segment's revenues and 49% of the segment's earnings for the nine months ended September 30, 2012. Due to the concentration of business in South Korea, the International segment is exposed to potential losses resulting from economic, regulatory and geopolitical developments in that country, as well as foreign currency movements affecting the South Korean currency, which could have a significant impact on the segment's results and the Company's consolidated financial results.
