Stock Repurchase [Abstract] |
Stock Repurchase | STOCK REPURCHASE: In September 2017, CNX's Board of Directors approved a one-year stock repurchase program of up to $200,000. On October 30, 2017, the Board approved an increase to the aggregate amount of the repurchase plan to $450,000. On July 30,2018, the Board approved the extension of the stock repurchase program through December 31, 2018. The repurchases may be effected from time-to-time through open market purchases, privately negotiated transactions, Rule 10b5-1 plans, accelerated stock repurchases, block trades, derivative contracts or otherwise in compliance with Rule 10b-18. The timing of any repurchases will be based on a number of factors, including available liquidity, the Company's stock price, the Company's financial outlook, and alternative investment options. The share repurchase program does not obligate the Company to repurchase any dollar amount or number of shares and the Board may modify, suspend, or discontinue its authorization of the program at any time. The Board of Directors will continue to evaluate the size of the stock repurchase program based on CNX's free cash flow position, leverage ratio, and capital plans. During the six months ended June 30, 2018, 11,086,082 shares were repurchased and retired at an average price of $15.20 per share for a total cost of $168,719.
