[1] Represents a charge of $49 million and the prior period portion of a reduction of revenue of $3 million and $2 million in the three and nine months ended September 30, 2020, respectively, related to the Mobile Bay Formosan termite settlement described in Note 6 to the condensed consolidated financial statements. We exclude these charges from Adjusted EBITDA because we believe they do not reflect our on-going operations and because we believe doing so is useful to investors in aiding period-to-period comparability.
