As a part of the Pinedale Divestiture, QEP agreed to reimburse the buyer for certain deficiency charges it incurs related to gas processing and NGL transportation and fractionation contracts between the effective date of the sale and December 31, 2019, in an aggregate amount not to exceed $45.0 million. As of September 30, 2018, the remaining liability associated with estimated future payments for this commitment was $23.0 million, which is reported on the Condensed Consolidated Balance Sheets within "Accounts payable and accrued expenses".
During the nine months ended September 30, 2018, QEP received net cash proceeds of $64.5 million and recorded a net pre-tax gain on sale of $37.9 million related to the divestiture of properties outside our main operating areas.
In addition to the Pinedale Divestiture, during the nine months ended September 30, 2017, QEP received net cash proceeds of $69.7 million, resulting in a net pre-tax gain on sale of $26.4 million, primarily related to the divestiture of certain non-core properties in the Other Northern area.
The gains and losses were recorded within "Net gain (loss) from asset sales, inclusive of restructuring costs" on the Condensed Consolidated Statements of Operations.
Note 4 – Earnings Per Share
Basic earnings per share (EPS) are computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the reporting period. Diluted EPS includes the potential increase in the number of outstanding shares that could result from the exercise of in-the-money stock options. QEP's unvested restricted share awards are included in weighted-average basic common shares outstanding because, once the shares are granted, the restricted share awards are considered issued and outstanding, the historical forfeiture rate is minimal and the restricted share awards are eligible to receive dividends.
Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents are considered participating securities and are included in the computation of earnings (loss) per share pursuant to the two-class method. The Company's unvested restricted share awards contain non-forfeitable dividend rights and participate equally with common stock with respect to dividends issued or declared. However, the Company's unvested restricted share awards do not have a contractual obligation to share in losses of the Company. The Company's unexercised stock options do not contain rights to dividends. Under the two-class method, the earnings used to determine basic earnings per common share are reduced by an amount allocated to participating securities. When the Company records a net loss, none of the loss is allocated to the participating securities since the securities are not obligated to share in Company losses. Use of the two-class method has an insignificant impact on the calculation of basic and diluted earnings (loss) per common share. During the three and nine months ended September 30, 2018 and 2017, there were no anti-dilutive shares.
The following is a reconciliation of the components of basic and diluted shares used in the EPS calculation:
Three Months Ended
Nine Months Ended
Weighted-average basic common shares outstanding
Potential number of shares issuable upon exercise of in-the-money stock options under the Long-Term Stock Incentive Plan
Average diluted common shares outstanding
