The Company analyzes its long-lived assets for impairment, both individually and as a group, whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. During the quarter ended June 30, 2011, an impairment charge in the amount of approximately $74.5 million was taken against Property, Plant and Equipment. This impairment, combined with a charge of approximately $3.5 million taken against Deposits on manufacturing equipment, resulted in a total write-down of $78.0 million in the quarter ended June 30, 2011. This write-down resulted in net assets of approximately $32.2 million being recorded at fair value as of June 30, 2011. The fair value measurement for these assets relied primarily on Company-specific inputs and the Company’s assumptions about the use of the assets, as observable inputs were not available. Accordingly, the Company determined that these fair value measurements reside primarily within Level 3 of the fair value hierarchy.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, to measure fair value:

• Level 1 - Quoted prices in active markets for identical assets or liabilities.

• Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

• Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Depreciation expense for the three months ended March 31, 2013 and 2012 was $1,533,629 and $1,441,262, respectively. Depreciation expense is recorded under “Research and development” expense and “Selling, general and administrative” expense in the Condensed Statements of Operations.
