Stock Repurchase Program | NOTE 11 — STOCK REPURCHASE PROGRAM On January 8, 2008, we announced our authorization of a stock repurchase program under which we may repurchase shares of RPM International Inc. common stock at management’s discretion for general corporate purposes. As announced on November 28, 2018, our goal is to return $1.5 billion in capital to stockholders by May 31, 2021 through dividends and share repurchases. As a result, we may repurchase shares from time to time in the open market or in private transactions at various times and in amounts and for prices that our management deems appropriate, subject to insider trading rules and other securities law restrictions. The timing of our purchases will depend upon prevailing market conditions, alternative uses of capital and other factors. We may limit or terminate the repurchase program at any time. During the three months ended February 28, 2019, we repurchased 1,570,647 shares of our common stock at a cost of approximately $91.2 million, or an average cost of $58.08 per share, under this program. During the nine months ended February 28, 2019, we repurchased 2,819,045 shares of our common stock at a cost of approximately $173.2 million, or an average cost of $61.45 per share, under this program.
