Controlling Shareholder [Abstract] |
Controlling Shareholder | 3. CONTROLLING SHAREHOLDER On April 30, 2010, we prepaid $15,0 00 of the original $25,0 00 principal outstanding on the Ton tine Term Loan. and $10,0 00 remains outstanding on the Tontine Term Loan. Although Tontine has not indicated any plans to alter its ownership level, s hould Tontine reconsider its investment plans and sell its controlling interest in the Company, a change in ownership w ould occur. A change in ownership, as defined by Internal Revenue Code Section 382, could reduce the availability of net operating losses for federal and state income tax purposes. Furthermore, a change in control would trigger the change of control provisions in a number of our material agreements, including our $40,000 Revolving Credit F acility, bonding agreements with our sureties and certain employment contracts with certain officers and employees of the Company.
