[1] | As disclosed in Note 4, Financial Statement Revisions, the company reported cash receipts and payments for the repurchase and sale of territories and cash paid at issuance of notes receivable at net when these transactions should have been disaggregated. We concluded that the errors were not material to any of these prior periods that were impacted. The error resulted in an understatement of cash flows from operating activities and cash flows used in investing activities of $5.9 million, $12.1 million and $12.8 million, respectively, for the sixteen, twenty-eight, and forty-week amounts included in the first, second, and third quarters of fiscal 2017, respectively. These amounts were revised upon subsequent presentation of these financial statements.
