FAIR VALUE MEASUREMENTS

Note 5: Fair Value Measurements

Fair value is defined as the 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. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as described below:

Level 1: Quoted prices in active markets for identical assets or liabilities

Level 2: Inputs that are derived principally from or corroborated by observable market data

Level 3: Inputs that are unobservable and significant to the overall fair value measurement

Our assets subject to fair value measurement on a recurring basis are summarized below:



	Level 1 Fair Value
	March 31	December 31	March 31
in thousands	2017	2016	2016
Fair Value Recurring
Rabbi Trust
Mutual funds	$ 5,148	$ 6,883	$ 6,185
Equities	10,608	10,033	6,824
Total	$ 15,756	$ 16,916	$ 13,009



	Level 2 Fair Value
	March 31	December 31	March 31
in thousands	2017	2016	2016
Fair Value Recurring
Rabbi Trust
Money market mutual fund	$ 2,849	$ 1,705	$ 2,682
Total	$ 2,849	$ 1,705	$ 2,682

We have two Rabbi Trusts for the purpose of providing a level of security for the employee nonqualified retirement and deferred compensation plans and for the directors' nonqualified deferred compensation plans. The fair values of these investments are estimated using a market approach. The Level 1 investments include mutual funds and equity securities for which quoted prices in active markets are available. Level 2 investments are stated at estimated fair value based on the underlying investments in the fund (short-term, highly liquid assets in commercial paper, short-term bonds and certificates of deposit).

Net gains of the Rabbi Trust investments were $239,000 and $82,000 for the three months ended March 31, 2017 and 2016, respectively. The portions of the net gains (losses) related to investments still held by the Rabbi Trusts at March 31, 2017 and 2016 were $(197,000) and $(1,024,000), respectively.

The carrying values of our cash equivalents, restricted cash, accounts and notes receivable, short-term debt, trade payables and accruals, and other current liabilities approximate their fair values because of the short-term nature of these instruments. Additional disclosures for derivative instruments and interest-bearing debt are presented in Notes 6 and 7, respectively.

Assets subject to fair value measurement on a nonrecurring basis are summarized below:



	Period ended March 31, 2017		Period ended March 31, 2016
		Impairment		Impairment
in thousands	Level 2	Charges	Level 2	Charges
Fair Value Nonrecurring
Property, plant & equipment, net	$ 0	$ 0	$ 0	$ 499
Other intangible assets, net	0	0	0	8,180
Other assets	0	0	0	967
Total	$ 0	$ 0	$ 0	$ 9,646

We recorded $9,646,000 of losses on impairment of long-lived assets for the three months ended March 31, 2016, reducing the carrying value of these Aggregates segment assets to their estimated fair value of $0. Fair value was estimated using a market approach (observed transactions involving comparable assets in similar locations).
