Segment Information

Segment Information

Our organizational structure is comprised of three reportable segments: Commercial and Specialty Business; Government Business; and Other.

Our Commercial and Specialty Business segment includes our Local Group, National Accounts, Individual and Specialty businesses. Business units in the Commercial and Specialty Business segment offer fully-insured health products; provide a broad array of managed care services to self-funded customers including claims processing, underwriting, stop loss insurance, actuarial services, provider network access, medical cost management, disease management, wellness programs and other administrative services; and provide an array of specialty and other insurance products and services such as dental, vision, life and disability insurance benefits, radiology benefit management and analytics-driven personal health care guidance.

Our Government Business segment includes Medicare and Medicaid businesses, National Government Services, or NGS, and services provided to the federal government in connection with FEP. Medicare business includes services such as Medicare Advantage, Medicare Part D, and Medicare Supplement. Medicaid business includes our managed care alternatives through publicly funded health care programs, including Medicaid, Temporary Assistance for Needy Family programs, programs for seniors and people with disabilities, programs for long-term services and support, Children’s Health Insurance Programs and ACA-related Medicaid expansion programs. NGS acts as a Medicare contractor for the federal government in several regions across the nation.

Our Other segment includes other businesses that do not individually meet the quantitative thresholds for an operating segment as defined by FASB guidance, as well as corporate expenses not allocated to the other reportable segments.

We define operating revenues, a non-GAAP measure, to include premium income, administrative fees and other revenues. Operating revenues are derived from premiums and fees received primarily from the sale and administration of health benefit products. Operating gain, a non-GAAP measure, is calculated as total operating revenue less benefit expense and selling, general and administrative expense.

Through our participation in various federal government programs, we generated approximately 18.2%, 18.8% and 21.0% of our total consolidated revenues from agencies of the U.S. government for the years ended December 31, 2016, 2015, and 2014, respectively. These revenues are contained in the Government Business segment.

The accounting policies of the segments are consistent with those described in the summary of significant accounting policies in Note 2, “Basis of Presentation and Significant Accounting Policies,” except that certain shared administrative expenses for each segment are recognized on a pro rata allocated basis, which in aggregate approximates the consolidated expense. Any difference between the allocated expenses and actual consolidated expense is included in other expenses not allocated to reportable segments. Intersegment sales and expenses are recorded at cost and eliminated in the consolidated financial statements. We evaluate performance of the reportable segments based on operating gain or loss as defined above. We evaluate net investment income, net realized gains on financial instruments, OTTI losses recognized in income, interest expense, amortization expense, gain or loss on extinguishment of debt, income taxes, assets and liabilities on a consolidated basis as these items are managed in a corporate shared service environment and are not the responsibility of segment operating management.

The classification between managed care products and managed care services in the above table primarily distinguishes between the level of risk assumed. Managed care products represent insurance products where we bear the insurance risk, whereas managed care services represent product offerings where we provide claims adjudication and other administrative services to the customer, but the customer principally bears the insurance risk. 

Asset, liability and equity details by reportable segment have not been disclosed, as we do not internally report such information.
