Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Conversion of Preferred Stock The Company has 40,000,000 authorized shares of preferred stock. In 2008, we issued 20,000 shares of mandatorily redeemable convertible preferred stock to a key employee in exchange for certain intellectual property rights. The preferred stock has a liquidation value of $10 per share and is convertible at any time prior April 13, 2013 into the Company's common stock on a one-for-one basis. On April 1, 2013, our key employee converted his 20,000 shares of mandatorily redeemable convertible preferred stock into common stock. Amendment to the Credit Facility On April 24, 2013, the Company entered into a third amendment to the Credit Facility (the “Third Amendment”) which provides for an increase in the revolving credit commitments under the Credit Facility from $105 million to $125 million and a decrease in the interest rate margin. Under the Credit Facility, outstanding borrowings bear interest at either a prime rate or a LIBOR rate, plus an applicable margin based upon the Company's leverage ratio. The Third Amendment decreases the applicable margin for the Company's outstanding borrowings (for both prime rate and LIBOR base rates) by 50 basis points at each leverage ratio threshold. The Third Amendment also contains amendments which (a) allow the Company to issue subordinated debt or convertible subordinated debt in an amount not to exceed $100 million, (b) provide the Company with the ability to repurchase up to $15 million worth of stock-based employee awards, and (c) allow for the Company to refinance its existing convertible junior subordinated debentures with the proceeds of certain issuances of subordinated debt or convertible subordinated debt.
