Medical

Medical expense primarily consists of both paid and unpaid medical expenses incurred to provide medical services and products to our members. Medical claims include fee-for-service claims, pharmacy benefits, capitation payments to providers, disputed provider claims and various other medical-related costs. Under fee-for-service claims arrangements with providers, we retain the financial responsibility for medical care provided and incur costs based on actual utilization of hospital and physician services. Medical claims are recognized in the period healthcare services are provided. Unpaid medical expenses include claims reported and in the process of being settled, but that have not yet been paid, as well as healthcare costs incurred but not yet reported to us, which are collectively referred to as benefits payable or claim reserves. The development of the claim reserve estimate is based on actuarial methodologies that consider underlying claim payment patterns, medical cost inflation, historical developments, such as claim inventory levels and claim receipt patterns, and other relevant factors. The methods for making such estimates and for establishing the resulting liability are continuously reviewed and any adjustments are reflected in the period determined. Medical expense also reflects the net impact of our ceded reinsurance claims from XOL and run-off quota share reinsurance contracts accounted for under reinsurance accounting.

Selling, General and Administrative Expenses

Selling, general and administrative expenses primarily include distribution and servicing costs, premium taxes, exchange fees, and other taxes and fees, employee-related expenses, costs of software and hardware, stock-based compensation, the impact of quota share reinsurance, and other administrative costs.

Other Expenses (Income)

Other expenses (income) consists primarily of miscellaneous expenses or income that are not core to our operations, including profit sharing arrangements with our co-branded health plans and changes in the fair value of financial instruments.

Income Tax Expense (Benefit)

Income tax expense (benefit) consists primarily of changes to our current and deferred federal and state tax assets and liabilities. Income taxes are recorded as deferred tax assets and deferred tax liabilities based on differences between the book and tax bases of assets and liabilities. Our deferred tax assets and liabilities are calculated by applying the current tax rates and laws to taxable years in which such differences are expected to reverse.

Net income (loss) attributable to noncontrolling interests

Net income (loss) attributable to noncontrolling interests represents the share of the Company’s earnings allocated to the Company’s joint venture partner.
