The following information shall not be deemed filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.<br><br>On November 9, 2017, Charles River Laboratories International, Inc. (the "Company" or the "Registrant") incorrectly reported the number of days sales outstanding (DSO) in its Form 10-Q for the period ended September 30, 2017. The Company reported a trailing twelve-month average DSO for the period ended September 30, 2017, which was inconsistent with its prior disclosure practice of reporting the DSO calculated for the exact date at the end of the quarter.  On a consistent reporting basis, the DSO was 61 days for the exact date as of September 30, 2017, an increase from 52 days as of December 31, 2016.  The increase was primarily driven by changes in the timing of certain working capital items related to integration of the information systems of WIL Research, which the Company acquired in 2016. The Company&#x2019;s DSO includes deferred revenue as an offset to accounts receivable, but is not adjusted for an allowance for doubtful accounts in the calculation.<br>
