Fair Value

The fair value of financial instruments is the amount at which the instrument could be exchanged in a current transaction between willing parties. Due to their short term nature, the Company believes that the carrying value of its accounts receivable, other current assets, accounts payable and other current liabilities approximate their fair values.

The Company classifies financial assets and liabilities into the following three levels based on the inputs used to measure fair value in the order of priority indicated:


•	Level 1- fair values are based on observable inputs such as quoted prices in active markets for identical assets or liabilities;


•	Level 2 - fair values are based on pricing inputs other than quoted prices in active markets for identical assets and liabilities and are either directly or indirectly observable as of the measurement date; and


•	Level 3- fair values are based on unobservable inputs in which little or no market data exists.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value requires judgment and may affect the placement of assets and liabilities within the fair value hierarchy levels.

The following table sets forth by level within the fair value hierarchy the Company's recurring financial assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2017 and December 31, 2016:



			Fair Value Measurements
	Carrying Value		Level 1	Level 2	Level 3
September 30, 2017
Assets:
Cash surrender value of life insurance policy	$	1,619	—	1,619	—
Liabilities:
Derivatives	$	405	—	405	—
December 31, 2016
Assets:
Cash surrender value of life insurance policy	$	1,188	—	1,188	—
Liabilities:
Derivatives	$	447	—	447	—

The Company's derivatives, which are comprised of interest rate swaps, are valued using a discounted cash flow analysis that incorporates observable market parameters, such as interest rate yield curves and credit risk adjustments that are necessary to reflect the probability of default by us or the counterparty. These derivatives are classified as a Level 2 measurement within the fair value hierarchy. See Note 11 for additional information on the Company's derivative instrument.

The Company's concrete construction segment has life insurance policies covering four employees with a combined face value of $11.1 million. The policies are invested in mutual funds and the fair value measurement of the cash surrender balance associated with these policies is determined using Level 2 inputs within the fair value hierarchy and will vary with investment performance. These assets are included in the "Other noncurrent" asset section in the consolidated balance sheets.

Other Fair Value Measurements

The fair value of the Company's debt at September 30, 2017 and December 31, 2016 approximated its carrying value of $82.1 million and $104.6 million, respectively, as interest is based on current market interest rates for debt with similar risk and maturity. If the Company's debt was measured at fair value, it would have been classified as a Level 2 measurement in the fair value hierarchy.
