10. Fair Value Measurements
The FASB has established a framework for measuring fair value using generally accepted accounting principles. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described as follows:
Level 1. Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets.
Level 2. Inputs to the valuation methodology include:
· Quoted prices for similar assets or liabilities in active markets
· Quoted prices for identical or similar assets or liabilities in inactive markets
· Inputs other than quoted prices that are observable for the asset or liability
· Inputs that are derived principally from or corroborated by observable market data by correlation or other means
If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.
Level 3. Inputs to the valuation methodology are unobservable and significant to the fair value measurement.
The asset or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.
The table below presents assets and liabilities that are measured at fair value on a recurring basis at December 31, 2012 and are categorized using the fair value hierarchy (in thousands):
Cash equivalents include cash held in money market and U.S. treasury funds at December 31, 2012.
The table below presents our assets and liabilities that are measured at fair value on a recurring basis during the fiscal year ended March 31, 2012 and are categorized using the fair value hierarchy (in thousands):
Basis for Valuation
The carrying values reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable and accounts payable approximate fair values because of the immediate or short-term maturities of these financial instruments. As the Company’s obligations under the revolving credit facility are based on adjustable market interest rates, the Company has determined that the carrying value approximates the fair value. The carrying values and estimated fair values of these obligations are as follows (in thousands):
The fair value of the Company’s warrant liability (see Note 9—Underwritten and Registered Direct Placements of Common Stock) recorded in the Company’s financial statements is determined using the Monte—Carlo simulation valuation method and the quoted price of the Company’s common stock in an active market, a Level 3 measurement. Volatility is based on the actual market activity of the Company’s stock. The expected life is based on the remaining contractual term of the warrants and the risk free interest rate is based on the implied yield available on U.S. Treasury Securities with a maturity equivalent to the warrants’ expected life. Different estimates and assumptions could produce different financial results.
The Company calculated the estimated fair value of warrants on the date of issuance and at each subsequent reporting date using the following assumptions:
From time to time, the Company issues common stock warrants that are derivative instruments. The Company does not enter into speculative derivative agreements and does not enter into derivative agreements for the purpose of hedging risks.
As discussed above, the Company adopted authoritative guidance issued by the FASB on contracts in an entity’s own equity that requires the common stock warrants to be classified as liabilities at their estimated fair value with changes in fair value at each reporting date recognized in the statement of operations.
The table below provides a reconciliation of the beginning and ending balances for the warrant liability which is measured at fair value using significant unobservable inputs (Level 3) (in thousands):
The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
