"within the scope of our Company’s buy-back program"

A share buy-back program is when a company uses cash (or borrows) to buy its own stock from the open market or shareholders, reducing the number of shares available to investors. For investors this matters because fewer shares can raise earnings per share and often support the stock price, while signaling that management believes the shares are a good use of cash—similar to a retailer buying back coupons so each remaining coupon becomes relatively more valuable.
