Endurance Specialty (ENH) is urging fellow shareholders of Aspen Insurance (AHL) to "tell Aspen's board and management it's time to put entrenched interests aside and focus on the clear benefits of Endurance's offer." In a letter being sent to Aspen shareholders, Endurance requests that Aspen shareholders vote FOR its proposals to requisition a special general meeting of shareholders in connection with Endurance's proposal to increase the size of Aspen's board of directors from 12 to 19 directors and to authorize support for the proposal of a Scheme of Arrangement by Endurance. By voting FOR Endurance's two proposals on the WHITE card, Aspen shareholders would be taking concrete action towards realizing the significant upfront premium and opportunity for long-term value of Endurance's offer.
