ITG Declares Quarterly Dividend and Increases Share Repurchase Authorization

NEW YORK, February 15, 2018 — ITG (NYSE: ITG) today announced that its Board of Directors has declared a regular quarterly cash dividend of $0.07 per share on the company’s common stock. The dividend is payable on March 15, 2018, to stockholders of record at the close of business on February 27, 2018.

The Board of Directors also authorized the repurchase of an additional 4 million shares, bringing the total number of shares currently available for repurchase to 4.4 million shares. As previously noted, ITG intends to continue share repurchases in an amount sufficient to offset all the dilution from share issuances on the vesting of employee stock awards during 2018. The timing and number of shares repurchased will be dependent on a variety of factors, including market and business conditions and competing needs for the use of capital.
