I need a thorough case study report for a health insurance firm named: HUMANA. Case study report with the following topics covered below.

The firm's strategic moves/commitments that help to sustain its competitive advantage (Besanko's Chapters 7, 9 and 11)

Note: It would be good to find out if the firm is currently, or was recently, involved in these activities:

Merger or acquisition (Chapters 2 and 3)

Joint venture and/or strategic partnership (Chapter 3)

Entry into or exit from any geographic region or market segment (Chapter 6)

Value provided to customers (Bensako Chapter 9)):

1. Benefit (related to demand)

2. Costs (related to supply)
