Subsequent Events [Abstract]
Subsequent Events	11. Subsequent Events On October 24, 2012, the Company entered into the Second Amended and Restated Credit Agreement (the “Amended Credit Agreement”). The Amended Credit Agreement amends, supersedes, and restates the Credit Agreement dated May 31, 2007 (the “Credit Agreement”), and provides for a revolving loan, swing line loan and letters of credit in the aggregate amount of up to $165 million. In addition, the Amended Credit Agreement reflects reductions in the interest rates charged on outstanding balances and a reduction in the number of financial covenants. The Amended Credit Agreement will bear interest at rates related to LIBOR plus 1.75% to 2.75%, or the lending institution’s prime rate, plus 0.75% to 1.75%. The Amended Credit Agreement will expire on October 24, 2017. Borrowings under the Amended Credit Agreement are secured by substantially all of the Company’s accounts receivable, inventory and certain equipment. On October 24, 2012, the Company entered into a Ninth Amendment to the Amended and Restated Note Purchase and Private Shelf Agreement (the “Note Purchase Agreement”), which reflects changes in certain financial covenant requirements to generally conform to the Amended Credit Agreement.
