Item 8.01.     Other Events.

On October 24, 2017, the Company’s Board of Directors (the “Board”) approved a new share repurchase program that will enable the Company to repurchase up to twenty five million shares of its common stock. This new program will become effective once the Company’s previously disclosed twenty million share repurchase program is completed. As of September 30, 2017, there were 970,650 shares available for repurchase under the existing program. The Company plans to acquire shares in open market transactions that may use a 10b5-1 plan, and may also repurchase shares via accelerated stock buyback programs, tender offers, privately negotiated transactions or by other means. Repurchases under this new program will be funded from one or a combination of existing cash balances, future free cash flow and indebtedness. The Company is not obligated to acquire any specific amount of common stock within any particular timeframe as a result of its new share repurchase program. The timing and amount of future repurchase activity under the new program will depend on market conditions, corporate considerations, debt agreements, and regulatory requirements. The new program may be modified, suspended or terminated at any time by the Board.
