David Michael Cordani - Cigna Corp.
Management
Good morning. It's David. First, importantly, when we think about, as I noted as before, the Specialty portfolio, we don't think about it simply as a cross-selling opportunity. That chapter has long since passed. We think about it as, how do you get the right dimension of integrated solutions for the benefit of employers, and ultimately their employees are our customers. You can think about as a cornerstone for us, we've been able to prove an outstanding result for the benefit of client and customers when you have at a minimum an intersection of medical, pharmacy, behavioral, that takes you to kind of life management, as well as targeted population health solutions. Operative term, targeted. So, you mine the data, you understand the health burden and the challenges of an employer or client, and you have targeted population-based health programs. Beyond that, then there's additional services. Our Dental portfolio continues to perform extraordinarily well. There's additional services above and beyond that. Lastly, as an example, while the market may not think about it as a Specialty offering, nor do we in a classic sense, we referenced One Guide, with 2 million lives on it this year, going to 4 million lives next year. It's a tremendous customer engagement, customer navigation, support set of capabilities that both individual customers benefit from, as do our clinical and service coworkers in terms of driving that on a go-forward basis. So, the key is it's a foundational body between the medical, pharmacy, behavioral and life management. And then we augment that and then bring additional services and tools beyond that. As it relates to Life and Disability, no. Not any one unique item, especially from a one-timer standpoint. We're quite pleased to see the trajectory and the momentum that we've been able to build in 2017. And we remain fully on track with our goal, which is to step into 2018 with our underlying run rate health for that business.
