Derivative Instruments and Hedging Activities Disclosure [Text Block]

10. Financial Instruments

Derivatives

The Company is exposed to market risk for changes in foreign currency exchange rates due to the global nature of its operations. In order to manage this risk the Company has hedged portions of its forecasted sales and purchases, which occur within the next twelve months and are denominated in non-functional currencies, with currency forward or collar contracts designated as cash flow hedges. At December 31, 2016 and 2015, the Company had contracts with U.S. dollar equivalent notional amounts of $59,932 and $37,735, respectively, to exchange foreign currencies, principally the Chinese Yuan, Pound Sterling, U.S. Dollar, Swedish Krona, Euro, Canadian Dollar, Japanese Yen and Swiss Franc. The Company believes it is probable that all forecasted cash flow transactions will occur.

In addition, the Company had outstanding contracts at December 31, 2016 and 2015 with a total notional amount of $56,189 and $51,369, respectively, that are not designated as hedging instruments. These instruments are used to reduce the Company's exposure for operating receivables and payables that are denominated in non-functional currencies.

The following table sets forth the fair values of derivative instruments held by the Company as of December 31, 2016 and 2015 and the balance sheet lines in which they are recorded:

	Fair Value Asset (Liability)
	December 31, 2016			December 31, 2015			Balance Sheet Caption
Foreign currency forward	$	1,058		$	170		Prepaid and other current assets
Foreign currency forward	(705		)	(452		)	Other accrued expenses

The amount of gains or losses from hedging activity recorded in earnings is not significant and the amount of unrealized gains and losses from cash flow hedges which are expected to be reclassified to earnings in the next twelve months is not significant; therefore, additional tabular disclosures are not presented. There are no amounts excluded from the assessment of hedge effectiveness and the Company's derivative instruments that are subject to credit risk contingent features were not significant.

The Company is exposed to credit loss in the event of nonperformance by counterparties to the financial instrument contracts held by the Company; however, nonperformance by these counterparties is considered unlikely as the Company’s policy is to contract with highly-rated, diversified counterparties.

The Company has designated the €300,000 and €600,000 of euro-denominated notes issued December 4, 2013 and November 9, 2016, respectively, as a hedge of a portion of its net investment in euro-denominated operations. Changes in the value of the euro-denominated debt are recognized in foreign currency translation adjustments within other comprehensive earnings (loss) of the Consolidated Statements of Comprehensive Earnings to offset changes in the value of the net investment in euro-denominated operations. Additionally, the Company's floating-to-floating cross currency swap agreement in exchange for swiss francs matured on October 15, 2015, and was also designated as a hedge of a portion of our net investment in non-U.S. operations. Changes in the value of the euro-denominated debt and the Swiss Franc cross-currency swap, resulting from exchange rate differences are offset by changes in the net investment due to the high degree of effectiveness between the hedging instruments and the exposure being hedged.

Amounts recognized in Other comprehensive earnings (loss) for the gains (losses) on its net investment hedges were as follows:

	2016			2015			2014
Gain on euro-denominated debt	$	53,791		$	35,458		$	47,630
(Loss)/gain on swiss franc cross-currency swap	—			(2,185		)	8,149
Total gain on net investment hedges before tax	53,791			33,273			55,779
Tax expense	(18,827		)	(11,646		)	(19,523		)
Gain on net investment hedges, net of tax	$	34,964		$	21,627		$	36,256

Fair Value Measurements

Accounting Standards Codification ("ASC") 820, "Fair Value Measurements and Disclosures," establishes a hierarchy for measuring fair value. A financial instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. ASC 820 establishes three levels of inputs that may be used to measure fair value as follows:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 inputs include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities 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 assets or liabilities.

Level 3 inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The Company's assets and liabilities measured at fair value on a recurring basis as of December 31, 2016 and 2015 were as follows:

	December 31, 2016		December 31, 2015
	Level 2		Level 2
Assets:
Foreign currency cash flow hedges	$	1,058	$	170
Liabilities:
Foreign currency cash flow hedges	705		452

The derivative contracts are measured at fair value using models based on observable market inputs such as foreign currency exchange rates and interest rates; therefore, they are classified within Level 2 of the fair value hierarchy.

In addition to fair value disclosure requirements related to financial instruments carried at fair value, accounting standards require disclosures regarding the fair value of all of the Company’s financial instruments. The estimated fair value of long-term debt at December 31, 2016 and 2015 was $3,534,553 and $2,880,734, respectively, compared to the carrying value of $3,206,637 and $2,603,655, respectively. The estimated fair value of long-term debt is based on quoted market prices for similar instruments and is, therefore, classified as Level 2 within the fair value hierarchy. The carrying values of cash equivalents, trade receivables, accounts payable and notes payable are reasonable estimates of their fair values as of December 31, 2016 and 2015 due to the short-term nature of these instruments.
