TORONTO, Canada, July 13, 2017 – Colliers International Group Inc. (NASDAQ: CIGI) (TSX: CIGI) (“Colliers”) announced today that the Toronto Stock Exchange (the “TSX”) has accepted a notice filed by Colliers of its intention to make a normal course issuer bid (the “NCIB”) with respect to its outstanding subordinate voting shares (the “Subordinate Voting Shares”).

The notice provides that Colliers may, during the twelve month period commencing July 18, 2017 and ending no later than July 17, 2018, purchase through the facilities of the TSX, alternative Canadian Trading Systems or The NASDAQ Stock Market (“Nasdaq”) up to 2,700,000 Subordinate Voting Shares in total, being approximately 10% of the “public float” as of July 1, 2017 of such class of shares. Purchases of Subordinate Voting Shares through Nasdaq will be made in the normal course and will not, during the twelve month period ending July 17, 2018 exceed, in the aggregate, 5% of the outstanding Subordinate Voting Shares as at the commencement of the NCIB. The price which Colliers will pay for any such shares will be the market price at the time of acquisition. During the period of this NCIB, Colliers may make purchases under the NCIB by means of open market transactions or otherwise as permitted by the TSX and/or Nasdaq. The actual number of Subordinate Voting Shares which may be purchased pursuant to the NCIB and the timing of any such purchases will be determined by senior management of Colliers. The average daily trading volume on the TSX from January 1, 2017 to June 30, 2017 was 45,237 Subordinate Voting Shares. Daily purchases under the NCIB will be limited to 11,309 Subordinate Voting Shares, other than block purchases. All shares purchased by Colliers under the NCIB will be cancelled.

As of July 1, 2017, there were 37,515,992 Subordinate Voting Shares and 1,325,694 multiple voting shares of Colliers outstanding.

Colliers may purchase its Subordinate Voting Shares, from time to time, if it believes that the market price of its Subordinate Voting Shares is attractive and that the purchase would be an appropriate use of corporate funds and in the best interests of Colliers.

Colliers’ previous NCIB expires on July 17, 2017. As of the date hereof, Colliers has not purchased any of its Subordinate Voting Shares under this NCIB.
