There were no transfers in and/or out of Level 1, Level 2 or Level 3 fair value measurements during the nine months ended June 30, 2013 and 2012, respectively.

The compound embedded derivative liability, which was included in long-term liabilities, represented the value of the equity conversion feature and a “make-whole” feature of the 2014 Debentures. The make-whole payment for foregone interest expired October 30, 2012, and upon its expiration, the compound embedded derivative no longer met the criteria for bifurcation as all components of the derivative were indexed to our own stock.

We measure the fair value of our Term A and B Loans and 2014 Debentures carried at amortized/accreted cost quarterly for disclosure purposes.

We use a binomial-lattice model to estimate fair values of our Term B Loan and 2014 Debenture financial instruments. The key unobservable input utilized in the model includes a discount rate of 6.4% and 6.5%, respectively. The estimated fair value of our Term A Loan is determined using Level 3 inputs based primarily on the comparability of its terms to the terms we could obtain, for similar instruments, in the current market.

The estimated fair values of our financial instruments are as follows:
