Equity [Abstract]
ISSUANCE AND REPURCHASE OF COMMON STOCK	ISSUANCE AND REPURCHASE OF COMMON STOCK At-the-Market Equity Issuance Program. On November 28, 2016, we filed with the SEC a prospectus supplement, to our October 2016 shelf registration statement on Form S-3 (the “Shelf Registration Statement”), under which we could have sold up to $150.0 million of our common stock through an “at-the-market” equity offering program (the “ATM Program”). Through December 31, 2016, we sold 167,931 shares of common stock under the ATM Program. The net proceeds from such sales were $6.0 million after deducting the aggregate commissions paid of approximately $0.1 million and were used to reduce outstanding indebtedness. No shares of common stock were sold under the ATM Program during 2017. On July 31, 2017, we delivered written notice to Merrill Lynch, Pierce, Fenner & Smith Incorporated, Raymond James & Associates, Inc. and SunTrust Robinson Humphrey, Inc. (collectively, the “Agents”) of our termination of the ATM Equity Offering^SM Sales Agreement, dated November 28, 2016 (the “Sales Agreement”), pursuant to Section 9(a) thereof. The Sales Agreement was terminable by us or the Agents for any reason at any time without penalty upon three days’ written notice to the other party. In connection with the filing of the Shelf Registration Statement and the commencement of the ATM Program, we capitalized costs totaling $0.7 million, substantially all of which was written off to selling, general and administrative expense in 2017 after the cancellation of the ATM Program. Common Stock Repurchase Plan. On June 23, 2014, our Board authorized an increase in the stock repurchase plan limit to $50.0 million (less $13.3 million repurchased previously). During year ended May 31, 2015, we repurchased 546,977 shares for a total cost of $21.1 million. During the year ended December 31, 2016, we repurchased 274,110 shares for a total cost of $7.6 million. In the fourth quarter of 2016, these 821,087 shares were retired and are not included in common stock issued and outstanding as of December 31, 2016. The retirement of the shares resulted in a reduction in common stock of $0.2 million, a reduction of $9.1 million to additional paid-in capital, and a $19.4 million reduction to retained earnings. No shares were repurchased during the year ended December 31, 2017. At December 31, 2017, $7.9 million remained available to repurchase shares under the stock repurchase plan. Under the Credit Facility, the Company is limited in its ability to make stock repurchases unless the Total Leverage Ratio is below 2.50 to 1.00. Notwithstanding such provision, in the event that after giving pro forma effect to such repurchase, if Liquidity (as defined in the Credit Agreement) is at least $15.0 million and the Total Leverage Ratio is less than or equal to 4.00 to 1.00, the Credit Facility generally permits the Company to make stock repurchases provided that such repurchases, plus any payments of cash dividends, do not exceed $50.0 million in the aggregate.
