Might want to have a look-see at the the 3/22/2018 report, the 4/22/2018 report and the 4/25/2018 report.
Is a company subject to any reporting requirements in connection with its repurchase program?
Yes. Item 703 of Regulation S-K requires that, for all issuer repurchases of equity securities (whether an open market or private transaction), the company must disclose in its next periodic report the following information, in tabular form, for each month of the preceding fiscal quarter:
the total number of shares purchased; the average price paid per share; the number of shares purchased as part of a publicly announced program; and the maximum number of shares (or approximate dollar value) that may yet be repurchased under the program. Additionally, for publicly announced programs, the SEC requires disclosure (in footnotes to the table) of the following information:
the date of the announcement the share or dollar amount approved by the board of directors; the expiration date (if any) of the program; each program that has expired during the last fiscal quarter; and each program that the issuer has determined to terminate prior to expiration or under which the issuer does not intend to make further purchases.
