Fair Value

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurement provisions establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. This guidance describes three levels of inputs that may be used to measure fair value:


•	Level 1: Inputs are quoted prices (unadjusted) for identical assets or liabilities in active markets.


•	Level 2: Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reported date.


•	Level 3: Unobservable inputs that are supported by little or no market activity and are developed based on the best information available in the circumstances. For example, inputs derived through extrapolation or interpolation that cannot be corroborated by observable market data.

Recurring Fair Value Measurements

As of September 30, 2017, the Company had derivative liabilities related to electricity, natural gas and foreign exchange contracts of less than $1, which were measured using level 2 inputs, and consisted of derivative instruments transacted primarily in over-the-counter markets. There were no transfers between Level 1, Level 2 or Level 3 measurements during the nine months ended September 30, 2017 or 2016.

The Company calculates the fair value of its Level 2 derivative liabilities using standard pricing models with market-based inputs, adjusted for nonperformance risk. When its financial instruments are in a liability position, the Company evaluates its credit risk as a component of fair value. At both September 30, 2017 and December 31, 2016, no adjustment was made by the Company to reduce its derivative position for nonperformance risk.

When its financial instruments are in an asset position, the Company is exposed to credit loss in the event of nonperformance by other parties to these contracts and evaluates their credit risk as a component of fair value.

Non-recurring Fair Value Measurements

Goodwill

In 2017, the Company lowered its forecast of estimated earnings and cash flows for its oilfield business from those previously projected, and indefinitely idled a manufacturing facility within its oilfield business. This was due to the slower than previously assumed recovery in the oil and gas market. As of September 30, 2017, the estimated fair value of the Company’s oilfield reporting unit was less than the carrying value of the net assets of the reporting unit. In estimating the fair value of the oilfield reporting unit, the Company relied solely on a discounted cash flow model income approach. This was due to the Company’s belief that the reporting unit’s EBITDA, a key input under the market approach, was not representative and consistent with the reporting unit’s historical performance and long-term outlook and, therefore, was not consistent with assumptions that a market participant would use in determining the fair value of the reporting unit. To measure the amount of the goodwill impairment, the Company allocated the estimated fair value of the reporting unit to the reporting unit’s assets and liabilities. As a result of this allocation, the Company estimated that the implied fair value of the oilfield reporting unit’s goodwill was $0. As such, the entire oilfield reporting unit’s goodwill balance of $13 was impaired during the third quarter of 2017, and the Company recognized a goodwill impairment charge of $13 in its Epoxy, Phenolic and Coating Resins segment, which is included in “Asset impairments” in the unaudited Condensed Consolidated Statements of Operations. Significant unobservable inputs in the discounted cash flow analysis included projected long-term future cash flows, projected growth rates and discount rates associated with this reporting unit. Future projected long-term cash flows and growth rates were derived from models based upon forecasts prepared by the Company’s management. These projected cash flows were discounted using a rate of 13.5%.

Non-derivative Financial Instruments

The following table summarizes the carrying amount and fair value of the Company’s non-derivative financial instruments:



	Carrying Amount		Fair Value
	Carrying Amount		Level 1		Level 2		Level 3		Total
September 30, 2017
Debt	$	3,777	$	—	$	3,205	$	31	$	3,236
December 31, 2016
Debt	$	3,542	$	—	$	3,134	$	9	$	3,143

Fair values of debt classified as Level 2 are determined based on other similar financial instruments, or based upon interest rates that are currently available to the Company for the issuance of debt with similar terms and maturities. Level 3 amounts represent capital leases whose fair value is determined through the use of present value and specific contract terms. The carrying amount and fair value of the Company’s debt is exclusive of unamortized deferred financing fees. The carrying amounts of cash and cash equivalents, short term investments, accounts receivable, accounts payable and other accrued liabilities are considered reasonable estimates of their fair values due to the short-term maturity of these financial instruments.
