The fair value of the Level 2 certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is the rate offered by the financial institution. The fair value of investment securities available for sale included in Level 1 are based on quoted market prices from various stock exchanges. The Level 2 investment securities available for sale are based on quoted market prices of securities that are thinly traded.

The fair value of derivatives embedded within convertible debt was derived using a valuation model. These derivatives have been classified as Level 3. The valuation model assumes future dividend payments by the Company and utilizes interest rates and credit spreads based upon the implied credit spread of the 5.50% Convertible Notes due 2020 to determine the fair value of the derivatives embedded within the convertible debt. The changes in fair value of derivatives embedded within convertible debt are presented on the consolidated statements of operations.

The value of the embedded derivatives is contingent on changes in implied interest rates of the convertible debt, the Company's stock price, stock volatility as well as projections of future cash and stock dividends over the term of the debt. The interest rate component of the value of the embedded derivative is computed by calculating an equivalent non-convertible, unsecured and subordinated borrowing cost. This rate is determined by calculating the implied rate on the Company's 2020 Convertible Notes when removing the embedded option value within the convertible security. This rate is based upon market observable inputs and influenced by the Company's stock price, convertible bond trading price, risk free interest rates and stock volatility.

The unobservable inputs related to the valuations of the Level 3 assets and liabilities were as follows at March 31, 2016:
