From the 12-31-11 10-K, Footnotes to financials (hopefully the conversion price of $22.47 per share will be a boon to the note holders);) LOL:

On December 12, 2006, the Company completed an offering of $115.0 million aggregate principal amount of 3.75% Senior Convertible Notes due 2013, including $15.0 million aggregate principal amount of the Notes due 2013 sold pursuant to the underwriters’ over-allotment option that was exercised in full. The Notes due 2013 are governed by the terms of an indenture dated as of November 1, 2006 and a First Supplemental Indenture, dated as of December 12, 2006 (the “2013 Note Indenture”). The Notes due 2013 bear interest at the rate of 3.75% per year on the principal amount, payable in cash semi-annually in arrears on June 15 and December 15 of each year, beginning June 15, 2007. The Company had accrued interest of $192,000 and $192,000 related to the Notes due 2013 for the years ended December 31, 2010 and 2011, respectively. The Notes due 2013 are general, unsecured, senior obligations of the Company and effectively rank junior in right of payment to all of the Company’s secured debt, to the extent of the value of the assets securing such debt, and to the debt and all other liabilities of the Company. The maturity date of the Notes due 2013 is December 15, 2013 and payment is due in full on that date for unconverted securities. Holders may convert, at any time prior to the close of business on the business day immediately preceding the stated maturity date, any outstanding Notes due 2013 into shares of the Company’s common stock at an initial conversion rate of 44.5002 shares per $1,000 principal amount of Notes due 2013, which is equal to a conversion price of approximately $22.47 per share, subject to adjustment. Except in certain circumstances, if the Company undergoes a fundamental change: (1) the Company will pay a make-whole premium on the Notes due 2013 converted in connection with a fundamental change by increasing the conversion rate on such Notes due 2013, which amount, if any, will be based on the Company’s common stock price and the effective date of the fundamental change, and (2) each holder of the Notes due 2013 will have the option to require the Company to repurchase all or any portion of such holder’s Notes due 2013 at a repurchase price of 100% of the principal amount of the Notes due 2013 to be repurchased plus accrued and unpaid interest, if any. Under the terms of the 2013 Note Indenture, the conversion option can be net-share settled and the maximum number of shares that could be required to be delivered under the contract, including the make-whole shares, is fixed and less than the number of authorized and unissued shares less the maximum number of shares that could be required to be delivered during the contract period under existing commitments. The Company performed an analysis at the time of the offering of the Notes due 2013 and each reporting date since and has concluded that the number of available authorized shares at the time of the offering and each subsequent reporting date was in excess of the maximum number of shares that could be required to be delivered during the contract period under existing commitments, including the outstanding convertible notes, stock options, restricted stock units, warrants and other potential common stock issuances.
