CLIENT EXPERIENCE
We aim to exceed your expectations, every day
Our strategy focuses on broad-based support across our client portfolios.

Breadth
We have the expertise, capacity, and market insight to meet our clients’ needs on a wide range of risks, including property and casualty. Our Specialty Lines teams offer expertise and solutions on Agriculture, Financial Risks, Cyber, and other specialty lines, to help our clients meet the challenges of these dynamic risks.

Ease
We want your experience with us to be the simplest part of your day. So our underwriting teams in Zurich, Bermuda, Miami, and New York work together to provide proportional and non-proportional capacity and expertise to our clients wherever they are in the world. No matter who you reach out to, we’ll connect you to the right person to address your needs.

Efficiency
Following significant investment, we’ve streamlined operations, and embedded new technology. For our clients, this means an increase in productivity, better decision-making, and data insights from us. But the real value of our approach lies in us being free to spend more time on building client relationships. By streamlining routine tasks, we create space for deeper client conversations, more creative problem-solving, and ultimately, better outcomes at a fair price.
Strategy
Our strategy drives us forward

At MS Reinsurance, we aim to manage the inherent volatility of our business by building a well-balanced and diversified portfolio of appropriately priced risks.
We create differentiated value by listening to and knowing our clients well, being easy to work with, and providing responsive, competitive solutions. We have reset our delivery model to meet these needs, build financial resilience, and create sustainable partnerships. We deliver on our strategy through:

- Empowered teams: Our underwriters are equipped to make fast, reliable decisions, moving at the pace our clients’ businesses demand. We find solutions through mutual understanding and commit early on solutions that work for both sides.
- Efficient platform: We have a cost-effective platform, built to deliver an exceptional client experience. To that end, we are developing a state-of-the-art operations platform that makes us even easier to work with, from a streamlined transaction process to enhanced data and stronger insights for clients.
