Dilutive earnings per share are computed similarly to basic earnings per share, except that the weighted average shares outstanding are increased to include additional shares from restricted stock units and performance share units, if dilutive. The number of additional shares is calculated by assuming that outstanding restricted stock units and performance share units were released, and that the proceeds from such activities were used to acquire shares of common stock at the average market price during the reporting period.

Generally, title passes when coal is loaded at the central preparation facility and, on occasion, at terminal locations or other customer destinations.

The estimated transaction price for each contract is allocated to the Company's performance obligations based on relative stand-alone selling prices determined at contract inception. The Company has determined that each ton of coal represents a separate and distinct performance obligation. Some of the Company's contracts span multiple years and have annual pricing modifications, based upon market-driven or inflationary adjustments, where no While CONSOL Energy does, from time to time, experience costs of obtaining coal customer contracts with amortization periods greater than one September 30, 2020 December 31, 2019 not three nine September 30, 2020 2019 not not not Terminal Revenue Terminal revenues are attributable to the Company's CONSOL Marine Terminal and include revenues earned from providing receipt and unloading of coal from rail cars, transporting coal from the receipt point to temporary storage or stockpile facilities located at the Terminal, stockpiling, blending, weighing, sampling, redelivery, and loading of coal onto vessels.

The fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. The fair value hierarchy is based on whether the inputs to valuation techniques are observable or unobservable.

Earnings Per Share, Policy [Policy Text Block]	Earnings per Share Basic earnings per share are computed by dividing net (loss) income attributable to CONSOL Energy Inc. shareholders by the weighted average shares outstanding during the reporting period. Dilutive earnings per share are computed similarly to basic earnings per share, except that the weighted average shares outstanding are increased to include additional shares from restricted stock units and performance share units, if dilutive. The number of additional shares is calculated by assuming that outstanding restricted stock units and performance share units were released, and that the proceeds from such activities were used to acquire shares of common stock at the average market price during the reporting period. The table below sets forth the share-based awards that have been excluded from the computation of diluted earnings per share because their effect would be anti-dilutive: Three Months Ended Nine Months Ended September 30, September 30, 2020 2019 2020 2019 Anti-Dilutive Restricted Stock Units 1,561,852 418,924 1,361,077 166,650 Anti-Dilutive Performance Share Units 29,062 56,399 32,736 — 1,590,914 475,323 1,393,813 166,650 The computations for basic and dilutive earnings per share are as follows: Three Months Ended Nine Months Ended Dollars in thousands, except per share data September 30, September 30, 2020 2019 2020 2019 Numerator: Net (Loss) Income $ (9,360 ) $ 7,024 $ (27,948 ) $ 76,157 Less: Net (Loss) Income Attributable to Noncontrolling Interest (2,136 ) 2,684 (5,108 ) 14,102 Net (Loss) Income Attributable to CONSOL Energy Inc.
