and applications require continual maintenance, upgrading and enhancement to meet our operational needs and regulatory requirements. We regularly upgrade and expand our information systems' capabilities. If we experience difficulties with the transition to or from information systems or do not appropriately integrate, maintain, enhance or expand our information systems, we could suffer, among other things, operational disruptions, loss of existing members and difficulty in attracting new members, regulatory problems and
increases in administrative expenses. In addition, our ability to integrate and manage our information systems may be impaired as the result of events outside our control, including acts of nature, such as earthquakes or fires, or acts of terrorists, which may include cyber-attacks by terrorists or other governmental or non-governmental actors. In addition, we may from time to time obtain significant portions of our systems-related or other services or facilities from independent third parties, which may make our operations vulnerable if such third parties fail to perform adequately.
An impairment charge with respect to our recorded goodwill and intangible assets could have a material impact on our results of operations.
We
periodically evaluate our goodwill and other intangible assets to determine whether all or a portion of their carrying values may be impaired, in which case a charge to earnings may be necessary. Changes in business strategy, government regulations or economic or market conditions have resulted and may result in impairments of our goodwill and other intangible assets at any time in the future. Our judgments regarding the existence of impairment indicators are based on, among other things, legal factors, market conditions, and operational performance. For example, the non-renewal of our health plan
contracts with the state in which they operate may be an indicator of impairment. If an event or events occur that would cause us to revise our estimates and assumptions used in analyzing the value of our goodwill and other intangible assets, such revision could result in a non-cash
impairment charge that could have a material impact on our results of operations in the period in which the impairment occurs.
A failure in or breach of our operational or security systems or infrastructure, or those of third parties with which we do business, including as a result of cyber-attacks, could have an adverse effect on our business.
Information security risks have significantly increased in recent years in part because of the proliferation of new technologies, the use of the internet and telecommunications technologies to conduct our operations, and the increased sophistication and activities of organized crime, hackers, terrorists and
other external parties, including foreign state agents. Our operations rely on the secure processing, transmission and storage of confidential, proprietary and other information in our computer systems and networks.
Security breaches may arise from external or internal threats. External breaches include hacking personal information for financial gain, attempting to cause harm or interruption to our operations, or intending to obtain competitive information. We experience attempted external hacking or malicious attacks on a regular basis. We maintain a rigorous system of prevention and detection controls through our security programs; however, our prevention and detection controls may not prevent or identify all such attacks on a timely basis, or at all. Internal breaches may result from inappropriate security access to confidential
information by rogue employees, consultants or third party service providers. Any security breach involving the misappropriation, loss or other unauthorized disclosure or use of confidential member information, financial data, competitively sensitive information, or other proprietary data, whether by us or a third party, could have a material adverse effect on our business reputation, financial condition, cash flows, or results of operations.
Risks Relating to Regulatory and Legal Matters
Reductions in funding, changes to eligibility requirements for government sponsored healthcare programs in which we participate and any inability on
our part to effectively adapt to changes to these programs could substantially affect our results of operations, financial position and cash flows.
The majority of our revenues come from government subsidized healthcare programs including Medicaid, Medicare, TRICARE, CHIP, LTSS, ABD, Foster Care and Health Insurance Marketplace premiums. Under most programs, the base premium rate paid for each program differs, depending on a combination of factors such as defined upper payment limits, a member's health status, age, gender, county or region and benefit mix. Since Medicaid was created in 1965, the federal government and the states have shared the costs for this program, with the federal share currently averaging approximately 60%. We are therefore exposed to risks associated with federal and state government contracting or participating
in programs involving a government payor, including
