Subsequent Events [Abstract] |
SUBSEQUENT EVENTS | NOTE 14 — SUBSEQUENT EVENTS In July 2012, we completed a public offering of 2,645,000 shares of our common stock at $34.75 per share. We plan to use the proceeds received from this offering for working capital and other general corporate purposes. The net proceeds from this offering were approximately $87.1 million. Also in July 2012, we entered into an unsecured revolving credit facility with four lenders, providing for total lending commitments of up to $125.0 million, of which $50.0 million will be available for the issuance of letters of credit. The unsecured revolving credit facility matures in July 2015.
