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 Balance Sheets as of December 26, 2020 and December 28, 2019:

	2020		2019		Fair Value Hierarchy Level
Liabilities:
Interest rate swaps (1)	$	440	$	1,653	Level 2

(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.
