We did not repurchase any shares of our common stock under this authorization during the nine months ended September 30, 2017.

During the first nine months of 2017, we issued 408,680 treasury shares which had an average cost of $3.15 per share for restricted stock units that vested during the period. In accordance with the Silgan Holdings Inc. Amended and Restated 2004 Stock Incentive Plan, we repurchased 138,080 shares of our common stock at an average cost of $30.24 to satisfy minimum employee withholding tax requirements resulting from the vesting of such restricted stock units. We account for treasury shares using the first-in, first-out (FIFO) cost method. As of September 30, 2017, 64.7 million shares of our common stock were held in treasury.
