Regarding CI, we discussed that it trades at a discount to the HMOs, which as a group trade at low multiples. We then illustrated that CI is a higher-quality business that generates superior and more stable returns on equity than its peer group. With a substantial emphasis on Administrative Services Only business, CI deserves a higher multiple closer to the business process outsourcing companies (such as ADP) than to the HMOs. CI also has a significant and growing Medicare Advantage business and a fast growing international business. Finally, we noted that since the vast majority of its customers are large and mid-sized enterprises, CI has much less exposure to the known risks of Obamacare including health care exchanges. In fact, Obamacare may provide a growth opportunity for the company because it may finally afford CI the opportunity to compete meaningfully in the in the individual segment of the market.
