The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Accounting estimates are based on historical experience and other factors that are considered reasonable under the circumstances. Estimates are used in determining such items as provisions for sales returns, rebates and incentives, chargebacks, and other sales allowances, depreciable/amortizable lives, asset impairments, valuation allowance on deferred taxes, amounts recorded for contingencies and accruals, and valuations of derivative and long-term debt instruments. Because of the uncertainties inherent in such estimates, actual results may differ from these estimates. Management periodically evaluates estimates used in the preparation of the consolidated financial statements for continued reasonableness. The results of operations for the years ended December 31, 2014 and 2013, respectively, are not necessarily indicative of the results for any future period.</font></p> </div>

The Company determined this redemption feature to be an embedded derivative, which is carried at fair value and is classified as Level 3 in the fair value hierarchy due to the use of significant unobservable inputs. The fair value of the embedded derivative was calculated using a probability-weighted model incorporating management estimates for potential change in control, and by determining the fair value of the debt with and without the change in control provision included. The difference between the two was determined to be the fair value of the embedded derivative. At December 31, 2014, the fair value of the derivative was determined to be $4.8 million, and the debt was valued by comparing debt issues of similar companies with (i) remaining terms of between 2.3 and 3.6 years, (ii) coupon rates of between 9.8% and 10.8% and (iii) market yields of between 10.0% and 16.8%. The Company recognized a $6.3 million gain on change in fair value of derivative liability for the year ended December 31, 2014. At December 31, 2013, the fair value of the derivative was determined to be $11.1 million, and the debt was valued by comparing debt issues of similar companies with (i) remaining terms of between 3.3 and 6.6 years, (ii) coupon rates of between 9.9% and 12.5% and (iii) market yields of between 9.0% and 29.4%. The Company recognized a $3.5 million gain on change in fair value of derivative liability for the year ended December 31, 2013.</font></p> <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px"><font style="FONT-FAMILY: Times New Roman" size="2">The Company’s 2014 Notes contain a redemption feature whereby, upon occurrence of a change in control, the Company would be required to repurchase the notes. The Company determined this redemption feature to be an embedded derivative, requiring bifurcation in accordance with ASC 815. The derivative is carried at fair value and is classified as Level 3 in the fair value hierarchy due to the use of significant unobservable inputs. The fair value of the embedded derivative was calculated using a probability-weighted model incorporating management estimates of the probability of a change in control occurring, and by determining the fair value of the debt with and without the change in control provision included. The difference between the two was determined to be the fair value of the embedded derivative. At December 31, 2014, the fair value of the derivative was determined to be $2.6 million, and the debt was valued by using (i) the estimated remaining term of the notes, (ii) a bond yield of 24.8%, (iii) a risk-free interest rate of 2.7% and (iv) volatility of 82.0%.
