Schedule of Fair Value, Assets and Liabilities Measured on Recurring Basis [Table Text Block]

The following table reflects the fair values of assets and liabilities measured and recognized at fair value on a recurring basis on the Company's Consolidated Condensed Balance Sheets as of March 31, 2018 and December 30, 2017:



	March 31, 2018		December 30, 2017		Fair Value Hierarchy Level
Assets:
Interest rate swaps (1)	$	120	$	—	Level 2

Liabilities:
Interest rate swaps (1)	$	1,304	$	2,229	Level 2
Contingent consideration (2)	25		25		Level 3

(1)

The Company uses certain external sources in deriving the fair value of the interest rate swaps. The interest rate swaps were valued using observable inputs (e.g., LIBOR yield curves, credit spreads). Valuations of interest rate swaps may fluctuate considerably from period-to-period due to volatility in underlying interest rates, which are driven by market conditions and the duration of the instrument. Credit adjustments could have a significant impact on the valuations due to changes in credit ratings of the Company or its counterparties.

(2)

As a result of the Robertex acquisition in 2013, the Company recorded a contingent consideration liability at fair value. This fair value measurement was based on calculations that utilize significant inputs not observable in the market including forecasted revenues, gross margins and discount rates and thus represent Level 3 measurements. This fair value measurement is directly impacted by the Company's estimates. Accordingly, if the estimates within the fair value measurement are higher or lower, the Company would record additional charges or benefits, respectively, as appropriate.
