Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company records certain financial instruments at fair value in accordance with the Fair Value Measurements and Disclosures Topic of the FASB ASC. Historically, the financial instruments to which this topic applied were foreign currency forward contracts and the fair value of these foreign currency forward contracts was recorded as a liability or asset in the consolidated balance sheets. During the second quarter of 2016, the Company ceased using foreign currency forward contracts to hedge foreign currency exposure as management determined its foreign currency exposure was no longer sufficiently significant to merit the use of hedging instruments. Therefore, no foreign currency forward contracts were outstanding as of September 30, 2017. The fair value of these derivative instruments was measured using models following quoted market prices in active markets for identical instruments, which is a Level 2 input under the fair value hierarchy of the Fair Value Measurements and Disclosures Topic of the FASB ASC. Additionally, the Company records pension assets at fair value. As of the last fair value measurement date of December 31, 2016, the net pension asset included plan assets with a fair value of $39.0 million. The plan assets consisted of debt and equity securities, real estate investment funds and cash and cash equivalents. The fair values of debt and equity securities are determined based on quoted prices in active markets for identical assets, which are Level 1 inputs under the fair value hierarchy. The fair value measurement of the real estate investment funds is based on unobservable inputs and assumptions which are Level 3 inputs under the fair value hierarchy. As of September 30, 2017, the fair value of the Company’s convertible senior notes issued in September 2017 is equivalent to the proceeds received of $37.8 million, due to the recent issuance of the Notes. The carrying value of short-term and other long-term borrowings approximates fair value because of the relative short maturity of these instruments and the interest rates the Company could currently obtain.
