Fair Value Measurement	Note 8 – Fair Value Measurement The Company bases fair value on a price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We have adopted a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and also considers counterparty credit risk in its assessment of fair value.

Note 8 – Fair Value Measurement

The Company bases fair value on a price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We have adopted a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Inputs, other than quoted market prices included in Level 1, that are observable either directly or indirectly for the asset or liability.

Level 3: Unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and also considers counterparty credit risk in its assessment of fair value.

Except for derivative instruments (see Note 7), pension liabilities, pension plan assets and a corporate owned life insurance policy, the Company had no material financial assets and liabilities that are carried at fair value at June 30, 2018 and December 31, 2017. The carrying amounts of financial instruments comprising cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the relatively short maturity of such instruments. The Company uses an income valuation technique to measure the fair values of its debt instruments by converting amounts of future cash flows to a single present value amount using rates based on current market expectations (Level 2 inputs).

As of June 30, 2018 and December 31, 2017, the carrying values of the Credit Agreement indebtedness were not materially different than their estimated fair values because the interest rates on variable rate debt approximated rates currently available to the Company (see Note 6). Discount rates used to measure the fair value of the DEG Vietnam Loan and DEG China Loan are based on quoted swap rates. As of June 30, 2018, the carrying values of the DEG Vietnam Loan and DEG China Loan was $12,500 and $1,400, respectively, as compared to an estimated fair value of $12,200 and $1,400, respectively. As of December 31, 2017, the carrying value of the DEG Vietnam Loan and DEG China Loan was $13,750 and $1,919, respectively, as compared to an estimated fair value of $13,600 and $2,000, respectively.

Certain Company assets are required to be recorded at fair value on a non-recurring basis when events and circumstances indicate that the carrying value may not be recoverable. As of June 30, 2018 and December 31, 2017, the Company did not realize any changes to the fair value of these assets due to the non-occurrence of events or circumstances that could negatively impact their recoverability.
