FAIR VALUE MEASUREMENTS:
 
The Company records its financial assets and liabilities at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants at the measurement date.
 
The authoritative guidance establishes a fair value hierarchy
that prioritizes the inputs to valuation techniques used to measure fair value into
three
broad levels. These levels are: Level 
1
(inputs are quoted prices in active markets for identical assets or liabilities); Level 
2
(inputs are other than quoted prices that are observable, either directly or indirectly through corroboration with observable market data); and Level 
3
(inputs are unobservable, with little or
no
market data that exists, such as internal financial forecasts). The Company is required to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The deferred compensation plan assets consist of cash and several publicly traded stock and bond mutual funds, valued using quoted market prices in active markets
, classified as Level 
1
within the fair value hierarchy, as well as guaranteed investment contracts, valued at principal plus interest credited at contract rates, classified as Level 
2
within the fair value hierarchy.
 
The Company
’s derivatives consist of foreign currency forward contracts, which are accounted for as cash flow hedges, and are valued using various pricing models or discounted cash flow analyses that incorporate observable market parameters, such as interest rate yield curves and currency rates, classified as Level 
2
within the fair value hierarchy. Derivative valuations incorporate credit risk adjustments that are necessary to reflect the probability of default by the counterparty or the Company.
 
The net carrying amounts of
cash and cash equivalents, trade and other receivables, accounts payable and accrued liabilities approximate fair value due to the short-term nature of these instruments.
 
Assets
Measured and Recorded at Fair Value on a Non
r
ecurring Basis
 
The Company
measures its financial assets, including non-marketable cost-method investments, at fair value on a nonrecurring basis when they are determined to be other-than-temporarily impaired. The fair value of these assets is determined using Level 
3
unobservable inputs due to the absence of observable market inputs, and because the valuations require management judgment. There were
no
material impairment charges recorded on investments during the years ended
December 
31,
2017,
2016
and
2015.
 
If required as part of its
goodwill impairment assessments, the Company calculates the business enterprise value of applicable reporting units. This calculation uses a weighted average of income and market approaches, and is classified as Level 
3
within the fair value hierarchy. The income approach is primarily driven by inputs from the Company’s internal financial forecasts. The market approach incorporates inputs from market participant data, as well as inputs derived from Company assumptions.
