such limits reverts to the cedant. Our Casualty and Specialty segment frequently provides coverage for relatively large limits or exposures, and thus we are subject to potential significant claims volatility. Our Casualty and Specialty segment also offers certain casualty insurance products through Syndicate 1458, including general liability, medical malpractice and professional liability. Syndicate 1458 also writes business through delegated authority arrangements. As a result of our financial strength, we have the ability to offer significant capacity and, for select risks, we have made available significant limits. We believe these capabilities, the strength of our casualty and specialty underwriting team, and our demonstrated ability and willingness to pay valid claims are competitive advantages of our casualty and specialty business. While we believe that these and other initiatives will support growth in our Casualty and Specialty segment, we intend to continue to apply our disciplined underwriting approach. Other Our Other category primarily includes the results of: (1) our share of strategic investments in certain markets we believe offer attractive risk-adjusted returns or where we believe our investment adds value, and where, rather than assuming exclusive management responsibilities ourselves, we partner with other market participants; (2) our investment unit which manages and invests the funds generated by our consolidated operations; and (3) corporate expenses, certain expenses related to acquisitions and dispositions, capital servicing costs and noncontrolling interests. Geographic Breakdown Our exposures are generally diversified across geographic zones, but are also a function of market conditions and opportunities. Our largest exposure has historically been to the U.S. and Caribbean market, which represented 50.8% o f our gross premiums written for the year ended December 31, 2021. A significant amount of our U.S. and Caribbean premium provides coverage against windstorms (mainly U.S. Atlantic hurricanes), earthquakes and other natural and man-made catastrophes.
