   1.                                                   We note your response
to our comment that your earnings releases do not contain material
                                                        non-public information.
Tell us why your earnings releases routinely and prominently
                                                        describe and attribute
changes in revenue as organic for both consolidated and segment
                                                        results. Tell us
whether organic revenue changes fluctuate between periods and why the
                                                        discussion is not
provided in your periodic reports. Provide us with your analysis that
                                                        organic changes in
revenues are not material non-public information.
