Item 8.01.      Other Events.

     On November 18, 2005, certain subsidiaries of XL Capital Ltd (the
"Company") entered into a quota share reinsurance treaty (the "Treaty") with
Cyrus Reinsurance Limited ("Cyrus Re"), a newly-formed Bermuda reinsurance
company, pursuant to which Cyrus Re will assume specified percentages of certain
lines of property catastrophe reinsurance and retrocession business underwritten
by the ceding companies for the 2006 and 2007 underwriting years (commencing
January 1, 2006 through and including July 1, 2007), subject to adjustment under
certain circumstances. Additional or alternative underwriting periods may be
added by mutual agreement of the parties. In addition, in certain circumstances,
Cyrus Re may extend at its option the coverage provided by the Treaty to the
ceding companies' 2008 and 2009 underwriting years subject to Cyrus Re's
depositing into a new trust for the benefit of the ceding companies capital
sufficient to support the reinsurance and retrocessions to be ceded. Cessions
pursuant to this provision for the 2008 and 2009 underwriting years would be at
a reduced rate.

     Cyrus Re has contributed $525 million into a trust for the benefit of the
ceding companies (the "Trust") to support the 2006 and 2007 coverages to be
ceded by them to Cyrus Re (subject to release from time to time if certain tests
are met). Total capitalization was determined based on a multiple of the 1,000
year modeled aggregate expected loss to Cyrus Re for the 2006 and 2007
underwriting periods in respect of the business to be ceded for such periods.

     Cyrus Re will retain the right to terminate coverage on a prospective basis
in the event of a ratings downgrade of any ceding company below "A-" by Standard
& Poor's or A.M. Best. The ceding companies will retain the right to terminate
their respective obligations to cede business to Cyrus Re if the assets held in
trust for their benefit do not meet certain tests.

     The ceding companies will pay to Cyrus Re reinsurance premium in the amount
of the ceded share of the original gross written premium on the business
reinsured with Cyrus Re less a ceding commission, which includes a reimbursement
of direct acquisition expenses as well as a commission to the ceding companies
for generating the business. The Treaty also provides for a profit commission to
the ceding companies.

     Highfields Capital Management LP, an investment management company in which
the Company holds a significant minority economic interest, manages certain
private investment funds which hold in the aggregate approximately 50% of the
equity interest in the parent of Cyrus Re. While subsidiaries of the Company are
investors in certain of these funds, they did not participate in the investments
in Cyrus Re's parent by these funds. These subsidiaries will, however,
indirectly benefit from any management and performance fees earned by the
investment management company on the investments made by its managed funds in
Cyrus Re's parent and any other fees earned by the management company as a
result of the Treaty, as it does on other investments by these funds. The
Company also expects to be a minority co-investor, along with the principals and
owners of Highfields Capital Management LP, in another investment management
enterprise that manages money for the Company and that has other clients which
invested in Cyrus Re's parent. The Company's funds managed by this enterprise
will not be invested in such parent, but the Company will in the ordinary course
share in any management fees earned by this enterprise as a result of
investments by its other clients in such parent.
