Fair Values

Pursuant to ASC 820, the inputs used to derive the fair value of assets and liabilities are analyzed and assigned a level I, II or III priority, with level I being the highest and level III being the lowest in the hierarchy. Level I inputs are quoted prices in active markets for identical assets or liabilities. Level II inputs are quoted prices for similar assets or liabilities in active markets: quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. Level III inputs are based on valuations derived from valuation techniques in which one or more significant inputs are unobservable. The following table provides a summary of the company’s assets and liabilities that are measured on a recurring basis (in thousands):

Forward Contracts: The company operates internationally and as a result is exposed to foreign currency fluctuations. Specifically, the exposure includes intercompany loans and third party sales or payments. In an attempt to reduce this exposure, foreign currency forward contracts are utilized and accounted for as hedging instruments. The forward contracts are used to hedge the following currencies: AUD, CAD, CHF, CNY, DKK, EUR, GBP, MXP, NOK, NZD, SEK and USD. The company does not use derivative financial instruments for speculative purposes. Fair values for the company’s foreign exchange forward contracts are based on quoted market prices for contracts with similar maturities. The carrying values and fair values of the company’s financial instruments are as follows (in thousands):

________

* The company's long-term debt is shown net of discount and fees associated with the Convertible Senior Notes due 2021 on the company's condensed consolidated balance sheet. Accordingly, the fair value of the Convertible Senior Notes due 2021 included in the long-term debt presented in this table is also shown net of the discount and fees.

The company, in estimating its fair value disclosures for financial instruments, used the following methods and assumptions:

Cash, cash equivalents: The carrying value reported in the balance sheet for cash, cash equivalents equals its fair value.

Other investments: The company has made other investments in limited partnerships and non-marketable equity securities, which are accounted for using the cost method, adjusted for any estimated declines in value. These investments were acquired in private placements and there are no quoted market prices or stated rates of return. The company does not have the ability to easily sell these investments. The company completes an evaluation of the residual value related to these investments in the fourth quarter each year.

Installment receivables: The carrying value reported in the balance sheet for installment receivables approximates its fair value. The interest rates associated with these receivables have not varied significantly since inception. Management believes that after consideration of the credit risk, the net book value of the installment receivables approximates market value.

Long-term debt: Fair value for the company’s convertible debt is based on quoted market-based estimates as of the end of the period, while the revolving credit facility fair value is based upon an estimate of the market for similar borrowing arrangements. The fair values are deemed to be categorized as Level 2 in the fair value hierarchy.

Convertible debt derivatives: The fair values for the convertible debt conversion liability and note hedge derivatives are based on valuation models in which all the significant inputs are observable in active markets.

Forward contracts: Fair values for the company’s foreign exchange forward contracts are based on quoted market prices for contracts with similar maturities.
