Fair Value Disclosures [Abstract] |
Cash and Cash Equivalents and Fair Value of Financial Instruments | Cash and Cash Equivalents and Fair Value of Financial Instruments Cash and cash equivalents of $32.4 million and $54.5 million as of December 31, 2017 and December 31, 2016, respectively, consisted of demand deposits only. Fair value hierarchy The Company measures its financial instruments at fair value. The Company’s cash equivalents are classified within Level 1 of the fair value hierarchy as they are valued primarily using quoted market prices utilizing market observable inputs. The Company's interest rate swap contracts and foreign currency contracts are classified within Level 2 as the valuation inputs are based on quoted prices and market observable data of similar instruments. The Company's contingent consideration liability related to the Avantec acquisition and was classified as Level 3 as valuation inputs were unobservable in the market and significant to the instrument’s valuation. The Company determined the final payout amount for the remaining contingent consideration and reduced the liability from $3.0 million to $2.4 million. The reduction of the contingent liability resulted in a gain of $0.6 million which is recorded in the "Interest and other income (expense), net" line in the Consolidated Statement of Operations for the year ended December 31, 2016. During the year ended December 31, 2017, the Company concluded that the final payout had been earned and paid out $2.4 million during the third quarter of 2017. The following table represents the fair value hierarchy of the Company’s financial assets measured at fair value as of December 31, 2017:

There have been no transfers between fair value measurement levels during the years ended December 31, 2017 and December 31, 2016. Foreign Currency Risk Management The Company operates in foreign countries, which expose it to market risk associated with foreign currency exchange rate fluctuations between the U.S. dollar and various foreign currencies, the most significant of which is the British Pound and the Euro. In order to manage foreign currency risk, at times the Company enters into foreign exchange forward contracts to mitigate risks associated with changes in spot exchange rates of mainly non-functional currency denominated assets or liabilities of the Company's foreign subsidiaries. In general, the market risk related to these contracts is offset by corresponding gains and losses on the hedged transactions. By working only with major banks and closely monitoring current market conditions, the Company seeks to limit the risk that counterparties to these contracts may be unable to perform. The foreign exchange forward contracts are measured at fair value and reported as other current assets or accrued liabilities on the Consolidated Balance Sheets. The derivative instruments the Company uses to hedge this exposure are not designated as hedges. Any gains or losses on the foreign exchange forward contracts are recognized in earnings as Other Income/Expense in the period incurred in the Consolidated Statements of Operations. The Company does not enter into derivative contracts for trading purposes. At December 31, 2017 and December 31, 2016, the Company had no outstanding foreign exchange forward contracts. Interest Rate Swap Contracts The Company uses interest rate swap agreements to protect the Company against adverse fluctuations in interest rates by reducing its exposure to variability in cash flows relating to interest payments on a portion of its outstanding debt. The Company's interest rate swaps, which are designated as cash flow hedges, involve the receipt of variable amounts from counterparties in exchange for the Company making fixed-rate payments over the life of the agreements. The Company does not hold or issue any derivative financial instruments for speculative trading purposes. During 2016, the Company entered into an interest rate swap agreement with a combined notional amount of $100.0 million with one counter-party that is effective beginning on June 30, 2016 and maturing on April 30, 2019. The swap agreement requires the Company to pay a fixed rate of 0.8% and provides that the Company will receive a variable rate based on the one month LIBOR rate subject to LIBOR floor of 0.0%. Amounts payable by or due to the Company will be net settled with the respective counter-party on the last business day of each month, commencing July 31, 2016. The fair value of the interest rate swap agreements at December 31, 2017 and December 31, 2016 was $1.4 million and $1.2 million, respectively. There were no amounts reclassified into current earnings due to ineffectiveness during the periods presented.
