Form 8-K dated February 5, 2019

Exhibit 99.2
Regulation G--Non-GAAP Financial Measures
Core Operating Income measures, page 33

2.       We refer to your non-GAAP measure "Core operating income excluding
catastrophe
         losses" and as further adjusted to exclude prior period development as
well as your
         rationale discussed on page 31 for presenting these non-GAAP measures.
While we note
         that you generally define loss events as catastrophic if they cause
damage of $25 million
         or more and affect a certain number of insureds (consistent with the
definition of the
         Property Claims Service), it appears that the nature of these losses
are integral to your
         operating results. Please tell us how you considered Question 100.01
of the Non-GAAP
         Compliance and Disclosure Interpretations. Further, by excluding prior
year development
         expenses recognized in the current period, it appears that you may be
substituting
         individually tailored recognition and measurement methods for those of
GAAP. Please
         tell us how you considered Question 100.04 of the Non-GAAP Compliance
and
         Disclosure Interpretations
3.       We refer to your non-GAAP measure "Core operating income with expected
level of
         catastrophe losses" which excludes catastrophe losses above or below
management's view
         of typical catastrophe losses for that period. The adjustment is
intended to present a
         performance measure with normalized catastrophe activity. By excluding
a portion of the
         losses incurred, it appears that you have substituted individually
tailored recognition and
         measurement methods for those of GAAP. Please tell us how you
considered Question
         100.04 of the Non-GAAP Compliance and Disclosure Interpretations
       In closing, we remind you that the company and its management are
responsible for the
accuracy and adequacy of their disclosures, notwithstanding any review,
comments, action or
absence of action by the staff.

      You may contact Christine Allen Torney at 202-551-3652 or Jim Rosenberg
at 202-551-
3679 with any questions.



                                                              Sincerely,

                                                              Division of
