| • | in 2016, the United Kingdom (U.K.) held a referendum in which voters approved an exit from the European Union (E.U.), commonly referred to as "Brexit."  As a result of the referendum, in 2017 the British government formally commenced the process to leave the E.U. and began negotiating the terms of treaties that will govern the U.K.'s future relationship with the E.U.  Although the terms of any future treaties are unknown, we believe changes in our international operating platform will be required to allow us to continue to write business in the E.U. after the completion of Brexit, therefore we have begun the process of establishing a new European subsidiary in Luxembourg.  As a result of these changes, the complexity and cost of regulatory compliance of our European business is likely to increase. |
