Item 8.01.       Other Events.

As previously reported, on December 29, 2005, Arch Reinsurance Ltd. (the “Ceding Company”), a subsidiary of Arch Capital Group Ltd., entered into a quota share reinsurance treaty (the “Treaty”) with Flatiron Re Ltd. (“Flatiron Re”), a newly-formed Bermuda reinsurance company, pursuant to which Flatiron Re is assuming a 45% quota share of certain lines of property and marine business underwritten by the Ceding Company for the 2006 and 2007 underwriting years (subject to extension by Flatiron Re to the Ceding Company’s 2008 underwriting year under certain circumstances). Effective June 28, 2006, the parties amended the Treaty to increase the percentage ceded to Flatiron Re from 45% to 70% of all covered business bound by the Ceding Company from (and including) June 28, 2006 until (and including) August 15, 2006 provided such business does not incept beyond September 30, 2006. The ceding percentage for all business bound outside of this period will continue to be 45%, subject to adjustment as provided under the Treaty.

Flatiron Re is required to contribute funds into a trust for the benefit of the Ceding Company (the “Trust”). Effective June 28, 2006, the parties amended the Treaty to provide that, for the period ending on December 31 of the final underwriting year covered by the Treaty, the amount required to be on deposit in the Trust, together with certain other amounts, is an amount equal to the greater of (1) $800 million and (2) a calculated amount estimated to cover ceded losses arising from in excess of two 1-in-250 year events for the applicable forward twelve-month period (the “Requisite Funded Amount”). For the period after the end of the final underwriting year covered by the Treaty through the earning of all written premium, the Requisite Funded Amount will be the calculated amount described in clause “(2)” above.
