Derivative liabilities

11. Derivative liabilities

The Company does not use derivative financial instruments to hedge exposures to cash-flow, market or foreign-currency risks. However, the Company has entered into certain other financial instruments and contracts, such as debt financing arrangements with features that are either (i) not afforded equity classification, (ii) embody risks not clearly and closely related to host contracts, or (iii) may be net-cash settled by the counterparty. These instruments are required to be carried as derivative liabilities, at fair value.

The following table discloses the fair value of the Company’s derivative liabilities as of December 31, 2012 and 2011. The Company held no asset derivatives at either reporting date.
