The Toronto Stock Exchange has accepted a notice filed by West Fraser Timber Co. Ltd. of its intention to amend its current normal course issuer bid (NCIB) to purchase up to an additional 2,196,079 of its common shares.

The amended TSX notice authorizes the company to, during the 12-month period commencing Sept. 19, 2017, and ending Sept. 18, 2018, purchase up to 5,990,454 common shares of the company, representing 10 per cent of the public float as at Sept. 12, 2017. Under its current NCIB, as of June 11, 2018, the company has purchased 2,061,389 common shares at an average price of $88.99 per common share, resulting in 3,929,065 common shares remaining available for purchase under the amended NCIB.

All shares will be purchased either on the open market through the facilities of the TSX or through other Canadian marketplaces, and payment for the shares will be made in accordance with TSX policies. The price paid for the shares will be the market price at the time of purchase. No purchases will be made other than by means of open market transactions during the term of the NCIB. The shares purchased by the company will be cancelled.

Pursuant to TSX policies, the daily purchases will not exceed 71,128 common shares, representing 25 per cent of the average daily trading volume of 284,514 common shares, except where such purchases are made in accordance with block purchase exemptions under applicable TSX policies.

West Fraser has also entered into a new automatic share purchase plan pursuant to which the securities dealer acting as the company's agent for the NCIB may acquire, at its discretion, common shares of West Fraser on West Fraser's behalf commencing June 14, 2018, to the expiry of the quarterly blackout period of the company for its second quarter 2018 results ending at the end of July 23, 2018, subject to certain parameters as to price and number of shares.
