title (&#x201c;control&#x201d;) of the product transfers to the purchaser, which differs depending on the applicable contractual terms.  Transfer of control drives the presentation of transportation, gathering, processing, and other post-production expenses (&#x201c;fees and other deductions&#x201d;) within the accompanying statements of operations.  Fees and other deductions incurred by the Company prior to control transfer are recorded within the oil, gas, and NGL production expense line item on the accompanying statements of operations.  When control is transferred at or near the wellhead, sales are based on a wellhead market price that is impacted by fees and other deductions incurred by the purchaser subsequent to the transfer of control.

The Company does not believe that significant judgments are required with respect to the determination of the transaction price, including amounts that represent variable consideration, as volume and price carry a low level of estimation uncertainty given the precision of volumetric measurements and the use of index pricing with generally predictable differentials.  Accordingly, the Company does not consider estimates of variable consideration to be constrained.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company&#x2019;s performance obligations arise upon the production of hydrocarbons from wells in which the Company has an ownership interest.  The performance obligations are considered satisfied upon control transferring to a purchaser at the wellhead, inlet, or tailgate of the midstream processor&#x2019;s processing facility, or other contractually specified delivery point.  The time period between &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;production and satisfaction of performance obligations is generally less than one day; thus, there are no material unsatisfied or partially unsatisfied performance obligations at the end of the reporting period.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Revenue is recorded in the month when performance obligations are satisfied.  However, settlement statements from the purchasers of hydrocarbons and the related cash consideration are received 30 to 90 days after production has occurred.  As a result, the Company must estimate the amount of production delivered to the customer and the consideration that will ultimately be received for sale of the product.  Estimated revenue due to the Company is recorded within the accounts receivable line item on the accompanying unaudited condensed consolidated balance sheets (&#x201c;accompanying balance sheets&#x201d;) until payment is received.  The accounts receivable balances from contracts with customers within the accompanying balance sheets as of September&#160;30, 2020, and December&#160;31, 2019, were $79.3 million and $146.3 million, respectively.  To estimate accounts receivable from contracts with customers, the Company uses knowledge of its properties, historical performance, contractual arrangements, index pricing, quality and transportation differentials, and other factors as the basis for these estimates.  Differences between estimates and actual amounts received for product sales are recorded in the month that payment is received from the purchaser.&lt;/span&gt;&lt;/div&gt;</us-gaap:RevenueFromContractWithCustomerTextBlock>

expense or benefit differs from the amounts that would be provided by applying the statutory United States federal income tax rate to income or loss before income taxes.  These differences primarily relate to the effect of state income taxes, excess tax benefits and deficiencies from stock-based compensation awards, tax limitations on the compensation of covered individuals, changes in valuation allowances, and the cumulative impact of other smaller permanent differences.  The quarterly rate can also be affected by the proportional impacts of forecasted net income or loss for each period presented, as reflected in the table above.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;During the third quarter of 2020, the proportional effect of recording discrete excess tax deficiencies from share-based compensation awards and other permanent items decreased the Company&#x2019;s effective tax rate for the three months ended September&#160;30, 2020, compared with the same period in 2019.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Coronavirus Aid, Relief, and Economic Security Act (&#x201c;CARES Act&#x201d;) was enacted on March 27, 2020.

Upon closing, the Company paid $8.9&#160;million of accrued and unpaid interest and accelerated $5.6&#160;million of previously unamortized deferred financing costs associated with the retired Senior Unsecured Notes and 2021 Senior Convertible Notes and accelerated $6.1&#160;million of previously unamortized debt discount associated with the retired 2021 Senior Convertible Notes.

In connection with the repurchases, the Company recorded a gain on extinguishment of debt of $25.1 million for the three months ended September&#160;30, 2020.  This amount included discounts realized upon repurchase of $25.5 million partially offset by approximately $480,000 of accelerated unamortized deferred financing costs.  During the three months ended March&#160;31, 2020, the Company repurchased a total of $40.7 million in aggregate principal amount of its 2022 Senior Notes in open market transactions for a total settlement amount, excluding accrued interest, of $28.3 million.  In connection with the repurchase, the Company recorded a gain on extinguishment of debt of $12.2 million for the three months ended March&#160;31, 2020.  This amount included discounts realized upon repurchase of $12.4 million partially offset by approximately $235,000 of accelerated unamortized deferred financing costs.

During the second quarter of 2020, as a result of lower commodity prices and a corresponding decrease in the value of the Company&#x2019;s proved reserves, the borrowing base and aggregate lender commitments under the Credit Agreement were both reduced to $1.1 billion.  Also during the second quarter of 2020, the Company entered into the Third Amendment and the Fourth Amendment to the Credit Agreement (collectively, the &#x201c;Amendments&#x201d;), which permitted the Company to incur new second lien debt of up to $827.5&#160;million prior to the fall semi-annual borrowing base redetermination, provided that all principal amounts of such debt are used to redeem unsecured senior debt of the Company for less than or equal to 80% of par value.  The Amendments also permitted the Company to grant a second-priority security interest to the holders of the Company&#x2019;s outstanding 2021 Senior Convertible Notes to secure the Company&#x2019;s obligations under the 2021 Senior Convertible Notes.  Additionally, the Amendments reduced the amount of dividends that the Company may declare and pay on an annual basis from $50.0 million to $12.0 million.  As of the filing of this report, the fall semi-annual borrowing base redetermination was in process.  The next scheduled borrowing base redetermination date is April 1, 2021.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Credit Agreement is scheduled to mature on September&#160;28, 2023, except that, pursuant to the Amendments, newly issued Permitted Second Lien Debt used to redeem any portion of the remaining 2022 Senior Notes must have maturities on or after 180 days after September&#160;28, 2023; otherwise, the maturity date of the Credit Agreement will be July 2, 2023.  Without regard to which maturity date is in effect, the maturity date could occur earlier on August 16, 2022, if the Company has not completed certain repurchase, redemption, or refinancing activities associated with its 2022 Senior Notes, and does not have certain unused availability for borrowing under the Credit Agreement, as outlined in the Credit Agreement.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Interest and commitment fees associated with the revolving credit facility are accrued based on a borrowing base utilization grid set forth in the Credit Agreement.  The Third Amendment to the Credit Agreement amended the borrowing base utilization grid as presented in the table below.  At the Company&#x2019;s election, borrowings under the Credit Agreement may be in the form of Eurodollar, Alternate Base Rate (&#x201c;ABR&#x201d;), or Swingline loans.  Eurodollar loans accrue interest at LIBOR, plus the applicable margin from the utilization grid, and ABR and Swingline loans accrue interest at a market-based floating rate, plus the applicable margin from the utilization grid.  Commitment fees are accrued on the unused portion of the aggregate lender commitment amount at rates from the utilization grid and are included in the interest expense line item on the accompanying statements of operations.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:3pt"&gt;&lt;table

During the nine months ended September&#160;30, 2020, the Company amended certain of its drilling rig contracts resulting in the reduction of day rates and potential early termination fees and the extension of contract terms.  As of September&#160;30, 2020, the Company&#x2019;s drilling rig commitments totaled $12.2 million under contract terms extending through the second quarter of 2021.  If all of these contracts were terminated as of the filing of this report, the Company would avoid a portion of the contractual service commitments; however, the Company would be required to pay $5.7 million in early termination fees.  No material expenses related to early termination or standby fees were incurred by the Company during the nine months ended September&#160;30, 2020, and the Company does not expect to incur material penalties with regard to its drilling rig contracts during the remainder of 2020.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Drilling and Completion Commitments&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;.  During the second quarter of 2020, the Company entered into an agreement that included minimum drilling and completion footage requirements on certain existing leases.  If these minimum requirements are not satisfied by March&#160;31, 2021, the Company will be required to pay liquidated damages based on the difference between the actual footage drilled and completed and the minimum requirements.  As of September&#160;30, 2020, the liquidated damages could range from zero to a maximum of $35.7 million, with the maximum exposure assuming no additional development activity occurred prior to March&#160;31, 2021.  The Company also entered into an agreement that included a minimum number of wells drilled and completed on certain existing leases.  If these minimum requirements are not satisfied by December&#160;31, 2021, the Company will be required to pay liquidated damages based on the difference between the actual number of wells drilled and completed and the minimum requirements.  As of September&#160;30, 2020, the liquidated damages could range from zero to a maximum of $11.5 million, with the maximum exposure assuming no additional development activity occurred prior to December&#160;31, 2021.  As of the filing of this report, the Company expects to meet its obligations under both agreements.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Contingencies&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company is subject to litigation and claims arising in the ordinary course of business.  The Company accrues for such items when a liability is both probable and the amount can be reasonably estimated.  In the opinion of management, the anticipated results of any pending litigation and claims are not expected to have a material effect on the results of operations, the financial position, or the cash flows of the Company.&lt;/span&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

The number of shares of the Company&#x2019;s common stock issued to settle PSUs ranges from zero to two times the number of PSUs awarded and is determined based on certain criteria over a three-year performance period.  PSUs generally vest on the third anniversary of the date of the grant or upon other triggering events as set forth in the Equity Plan.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;For PSUs granted in 2017, which the Company determined to be equity awards, the settlement criteria included a combination of the Company&#x2019;s Total Shareholder Return (&#x201c;TSR&#x201d;) on an absolute basis, and the Company&#x2019;s TSR relative to the TSR of certain peer companies over the associated three-year performance period.  The fair value of the PSUs granted in 2017 was measured on the grant &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;date using a stochastic Monte Carlo simulation using geometric Brownian motion (&#x201c;GBM Model&#x201d;).  As these awards depend entirely on market-based settlement criteria, the associated compensation expense is recognized on a straight-line basis within general and administrative expense and exploration expense over the vesting periods of the respective awards.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;For PSUs granted in 2018 and 2019, the settlement criteria include a combination of the Company&#x2019;s TSR relative to the TSR of certain peer companies and the Company&#x2019;s cash return on total capital invested (&#x201c;CRTCI&#x201d;) relative to the CRTCI of certain peer companies over the associated three-year performance period.  In addition to these performance criteria, the award agreements for these grants also stipulate that if the Company&#x2019;s absolute TSR is negative over the three-year performance period, the maximum number of shares of common stock that can be issued to settle outstanding PSUs is capped at one times the number of PSUs granted on the award date, regardless of the Company&#x2019;s TSR and CRTCI performance relative to its peer group.  The fair value of the PSUs granted in 2018 and 2019 was measured on the applicable grant dates using the GBM Model, with the assumption that the associated CRTCI performance condition will be met at the target amount at the end of the respective performance periods.  Compensation expense for PSUs is recognized within general and administrative expense and exploration expense over the vesting periods of the respective awards.  As these awards depend on a combination of performance-based settlement criteria and market-based settlement criteria, compensation expense may be adjusted in future periods as the number of units expected to vest increases or decreases based on the Company&#x2019;s expected CRTCI performance relative to the applicable peer companies.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company records compensation expense associated with the issuance of PSUs based on the fair value of the awards as of the date of grant.  Total compensation expense recorded for PSUs was $1.6 million and $2.9 million for the three months ended September&#160;30, 2020, and 2019, respectively, and $7.0 million and $8.6 million for the nine months ended September&#160;30, 2020, and 2019, respectively.  As of September&#160;30, 2020, there was $8.1 million of total unrecognized compensation expense related to non-vested PSU awards, which is being amortized through

The Company and the majority of grant participants mutually agreed to net share settle a portion of the awards to cover income and payroll tax withholdings, as provided for in the Equity Plan and applicable award agreements.  After withholding 215,451 shares to satisfy income and payroll tax withholding obligations that occurred upon delivery of the shares underlying those PSUs, 485,060 shares of the Company&#x2019;s common stock were issued in accordance with the terms of the applicable PSU awards.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Employee Restricted Stock Units&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company grants restricted stock units (&#x201c;RSUs&#x201d;) to eligible persons as part of its Equity Plan.  Each RSU represents a right to receive one share of the Company&#x2019;s common stock upon settlement of the award at the end of the specified vesting period.  RSUs generally vest one-third of the total grant on each anniversary date of the grant over a three-year vesting period or upon other triggering events as set forth in the Equity Plan.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company records compensation expense associated with the issuance of RSUs based on the fair value of the awards as of the date of grant.  The fair value of an RSU is equal to the closing price of the Company&#x2019;s common stock on the day of the grant.  Compensation expense for RSUs is recognized within general and administrative expense and exploration expense over the vesting periods of the respective awards.  Total compensation expense recorded for employee RSUs was $1.8 million and $2.9 million for the three months ended September&#160;30, 2020, and 2019, respectively and $7.1 million and $8.4 million for the nine months ended September&#160;30, 2020, and 2019, respectively.  As of September&#160;30, 2020, there was $8.6 million of total unrecognized compensation expense related to non-vested RSU awards, which is being amortized through

There were 297,013 and 184,079 shares issued under the ESPP during the nine months ended September 30, 2020, and 2019, respectively.  Total proceeds to the Company for the issuance of these shares was $947,000 and $2.0 million for the nine months ended September 30, 2020, and 2019, respectively.  The fair value of ESPP grants is measured at the date of grant using the Black-Scholes option-pricing model.&lt;/span&gt;&lt;/div&gt;</us-gaap:CompensationAndEmployeeBenefitPlansTextBlock>

Diluted net income or loss per common share is calculated by dividing net income or loss available to common stockholders by the diluted weighted-average number of common shares outstanding, which includes the effect of potentially dilutive securities.   As of September&#160;30, 2019, potentially dilutive securities for this calculation consisted primarily of non-vested RSUs, contingent PSUs, and shares into which the 2021 Senior Convertible Notes were convertible, which were measured using the treasury stock method.  Shares of the Company&#x2019;s common stock traded at an average closing price below the $40.50 conversion price applicable to the 2021 Senior Convertible Notes for the three and nine months ended September&#160;30, 2019, therefore, the 2021 Senior Convertible Notes had no dilutive impact.  On April 29, 2020, pursuant to the Third Supplemental Indenture, the Company agreed that it will satisfy any conversion obligation with respect to the 2021 Senior Convertible Notes solely in cash.  As a result, the Company&#x2019;s 2021 Senior Secured Convertible Notes are no longer convertible into shares of the Company&#x2019;s common stock and thus, were not considered to be a potentially dilutive instrument as of September&#160;30, 2020.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;On June&#160;17, 2020, the Company issued warrants to purchase up to an aggregate of approximately 5.9&#160;million shares, or approximately five percent of its outstanding common stock, at an exercise price of $0.01 per share, as discussed in &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Note 5 - Long-Term Debt&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;.

As of September&#160;30, 2020, all derivative counterparties were members of the Company&#x2019;s Credit Agreement lender group and all contracts were entered into for other-than-trading purposes.  The Company&#x2019;s commodity derivative contracts consist of swap and collar arrangements for oil production, and swap arrangements for gas and NGL production.  In a typical commodity swap agreement, if the agreed upon published third-party index price (&#x201c;index price&#x201d;) is lower than the swap fixed price, the Company receives the difference between the index price and the agreed upon swap fixed price.  If the index price is higher than the swap fixed price, the Company pays the difference.  For collar arrangements, the Company receives the difference between an agreed upon index price and the floor price if the index price is below the floor price.  The Company pays the difference between the agreed upon ceiling price and the index price if the index price is above the ceiling price.  No amounts are paid or received if the index price is between the floor and ceiling prices.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company has entered into fixed price oil basis swaps in order to mitigate exposure to adverse pricing differentials between certain industry benchmark prices and the actual physical pricing points where the Company&#x2019;s production volumes are sold.  Currently, the Company has basis swap contracts with fixed price differentials between New York Mercantile Exchange (&#x201c;NYMEX&#x201d;) WTI and WTI Midland for a portion of its Midland Basin production with sales contracts that settle at WTI Midland prices, and basis swap contracts with fixed price differentials between NYMEX WTI and Intercontinental Exchange Brent Crude (&#x201c;ICE Brent&#x201d;) for a portion of its Midland Basin oil production with sales contracts that settle at ICE Brent prices.  The Company has also entered into crude oil swap contracts to fix the differential in pricing between the NYMEX calendar month average and the physical crude oil delivery month (&#x201c;Roll Differential&#x201d;) in which the Company pays the periodic variable Roll Differential and receives a weighted-average fixed price differential.  The weighted-average fixed price differential represents the amount of net addition (reduction) to delivery month prices for the notional volumes covered by the swap contracts.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span

This guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date.  Market or observable inputs are the preferred sources of values, followed by assumptions based on hypothetical transactions in the absence of market inputs.  The fair value hierarchy for grouping these assets and liabilities is based on the significance level of the following inputs:&lt;/span&gt;&lt;/div&gt;&lt;div

Fair values are based upon interpolated data.  The Company derives internal valuation estimates taking into consideration forward commodity price curves, counterparties&#x2019; credit ratings, the Company&#x2019;s credit rating, and the time value of money.  These valuations are then compared to the respective counterparties&#x2019; mark-to-market statements.  The considered factors result in an estimated exit price that management believes provides a reasonable and consistent methodology for valuing derivative instruments.  The commodity derivative instruments utilized by the Company are not considered by management to be complex, structured, or illiquid.  The oil, gas, and NGL commodity derivative markets are highly active.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Please refer to &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Note 10 - Derivative Financial Instruments&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt; and to &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Note 11 - Fair Value Measurements &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;in the &lt;/span&gt;&lt;span style="color:#0000ff;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;&lt;a href="http://www.sec.gov/ix?doc=/Archives/edgar/data/893538/000089353820000009/sm-20191231x10k.htm" style="color:#0000ff;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;2019 Form 10-K&lt;/a&gt;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt; for more information regarding the Company&#x2019;s derivative instruments.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Oil and Gas Properties and Other Property and Equipment&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company had no assets included in total property and equipment, net, measured at fair value as of September&#160;30, 2020, or December&#160;31, 2019.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Proved oil and gas properties&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;.  Proved oil and gas property costs are evaluated for impairment and reduced to fair value when there is an indication that associated carrying costs may not be recoverable.  The Company uses an income valuation technique, which converts future cash flows to a single present value amount, to measure the fair value of proved properties using a discount rate, price and cost forecasts, and certain reserve risk-adjustment factors, as selected by the Company&#x2019;s management.  The Company uses a discount rate that represents a current market-based weighted average cost of capital.  The prices for oil and gas are forecast based on NYMEX strip pricing, adjusted for basis differentials, for the first five years, after which a flat terminal price is used for each commodity stream.  The prices for NGLs are forecasted using Oil Price Information Service (&#x201c;OPIS&#x201d;) Mont Belvieu pricing, for as long as the market is actively trading, after which a flat terminal price is used.  Future operating costs are also adjusted as deemed appropriate for these estimates.  Certain undeveloped reserve estimates are also risk-adjusted given the risk to related projected cash flows due to performance and exploitation uncertainties.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Other Property and Equipment.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;  Other property and equipment costs are evaluated for impairment and reduced to fair value when there is an indication the carrying costs may not be recoverable.  To measure the fair value of other property and equipment, the Company uses an income valuation technique or market approach depending on the quality of information available to support management&#x2019;s assumptions and the circumstances.  The valuation includes consideration of the proved and unproved assets supported by the property and equipment, future cash flows associated with the assets, and fixed costs necessary to operate and maintain the assets.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;No proved property impairment expense was recorded during the three months ended September&#160;30, 2020.  For the nine months ended September&#160;30, 2020, the Company recorded impairment expense of $956.7 million related to its South Texas proved oil and gas properties and related support facilities due to the decrease in commodity price forecasts at the end of the first quarter of 2020, specifically decreases in oil and NGL prices.  The Company used a discount rate of 11 percent in its calculation of the present value of expected future cash flows based on the prevailing market-based weighted average cost of capital as of March&#160;31, 2020.

The warrants are exercisable any time from and after the Triggering Date, as subsequently defined, until June 30, 2023.  The Triggering Date is defined by the Warrant Agreement as the first trading day following five consecutive trading days on which the product of the number of shares of common stock issued and outstanding on four of the five trading days multiplied by the closing price per share of common stock for each such trading day exceeds $1.0&#160;billion (&#x201c;Triggering Date&#x201d;).  The warrants issued are indexed to the Company&#x2019;s common stock and are required to be settled through physical settlement or net share settlement if exercised.  The warrants were not exercisable during the nine months ended September&#160;30, 2020, and through the filing of this report.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;margin-top:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The fair value of the warrants on the issuance date was determined using a stochastic Monte Carlo simulation using the GBM Model.  The Company evaluated the warrants under authoritative accounting guidance and determined that they should be classified as &lt;/span&gt;&lt;/div&gt;equity instruments.  Upon issuance, the warrants were recorded in additional paid-in capital on the accompanying balance sheets at a fair value of $21.5&#160;million, with no recurring fair value measurement required.  There have been no changes to the initial carrying amount of the warrants since issuance.</us-gaap:FairValueDisclosuresTextBlock>

Fair values are based upon interpolated data.  The Company derives internal valuation estimates taking into consideration forward commodity price curves, counterparties&#x2019; credit ratings, the Company&#x2019;s credit rating, and the time value of money.  These valuations are then compared to the respective counterparties&#x2019; mark-to-market statements.  The considered factors result in an estimated exit price that management believes provides a reasonable and consistent methodology for valuing derivative instruments.  The commodity derivative instruments utilized by the Company are not considered by management to be complex, structured, or illiquid.  The oil, gas, and NGL commodity derivative markets are highly active.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Please refer to &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Note 10 - Derivative Financial Instruments&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt; and to &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Note 11 - Fair Value Measurements &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;in the &lt;/span&gt;&lt;span style="color:#0000ff;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;&lt;a href="http://www.sec.gov/ix?doc=/Archives/edgar/data/893538/000089353820000009/sm-20191231x10k.htm" style="color:#0000ff;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;2019 Form 10-K&lt;/a&gt;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt; for more information regarding the Company&#x2019;s derivative instruments.&lt;/span&gt;&lt;/div&gt;</us-gaap:FairValueOfFinancialInstrumentsPolicy>

Proved oil and gas property costs are evaluated for impairment and reduced to fair value when there is an indication that associated carrying costs may not be recoverable.  The Company uses an income valuation technique, which converts future cash flows to a single present value amount, to measure the fair value of proved properties using a discount rate, price and cost forecasts, and certain reserve risk-adjustment factors, as selected by the Company&#x2019;s management.  The Company uses a discount rate that represents a current market-based weighted average cost of capital.  The prices for oil and gas are forecast based on NYMEX strip pricing, adjusted for basis differentials, for the first five years, after which a flat terminal price is used for each commodity stream.  The prices for NGLs are forecasted using Oil Price Information Service (&#x201c;OPIS&#x201d;) Mont Belvieu pricing, for as long as the market is actively trading, after which a flat terminal price is used.  Future operating costs are also adjusted as deemed appropriate for these estimates.

To measure the fair value of other property and equipment, the Company uses an income valuation technique or market approach depending on the quality of information available to support management&#x2019;s assumptions and the circumstances.  The valuation includes consideration of the proved and unproved assets supported by the property and equipment, future cash flows associated with the assets, and fixed costs necessary to operate and maintain the assets.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;No proved property impairment expense was recorded during the three months ended September&#160;30, 2020.  For the nine months ended September&#160;30, 2020, the Company recorded impairment expense of $956.7 million related to its South Texas proved oil and gas properties and related support facilities due to the decrease in commodity price forecasts at the end of the first quarter of 2020, specifically decreases in oil and NGL prices.  The Company used a discount rate of 11 percent in its calculation of the present value of expected future cash flows based on the prevailing market-based weighted average cost of capital as of March&#160;31, 2020.  No proved property impairment expense was recorded during the three or nine months ended September&#160;30, 2019.&lt;/span&gt;&lt;/div&gt;</us-gaap:PropertyPlantAndEquipmentImpairment>

As of September&#160;30, 2020, the Company did not have any agreements in place that were classified as finance leases under Topic 842.  Arrangements classified as operating leases are included on the accompanying balance sheets within the other noncurrent assets, other current liabilities, and other noncurrent liabilities line items.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;As outlined in Topic 842, a right-of-use (&#x201c;ROU&#x201d;) asset represents a lessee&#x2019;s right to use an underlying asset for the lease term, while the associated lease liability represents the lessee&#x2019;s obligations to make lease payments.  At the commencement date, which is the date on which a lessor makes an underlying asset available for use by a lessee, a lease ROU asset and corresponding lease liability is recognized based on the present value of the future lease payments.  Excluded from the initial measurement are certain variable lease payments, which for the Company&#x2019;s drilling rigs, completion crews, and midstream agreements, may be a significant component of the total lease costs.  Subsequent to initial measurement, costs associated with the Company&#x2019;s operating leases are either expensed on the accompanying statements of operations or capitalized on the accompanying balance sheets depending on the nature and use of the underlying ROU asset and in accordance with GAAP requirements.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Please refer to &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Note 12 - Leases&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt; in the &lt;/span&gt;&lt;span style="color:#0000ff;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;&lt;a href="http://www.sec.gov/ix?doc=/Archives/edgar/data/893538/000089353820000009/sm-20191231x10k.htm" style="color:#0000ff;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;2019 Form 10-K&lt;/a&gt;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt; for more information regarding the Company's policy on leases, and assumptions and judgments made in the initial and subsequent measurement of lease ROU assets and corresponding liabilities.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Currently, the Company has operating leases for asset classes that include office space, office equipment, drilling rigs, midstream agreements, vehicles, and equipment rentals used in field operations.  For those operating leases included on the accompanying balance sheets, which only includes leases with terms greater than 12 months at commencement, remaining lease terms range from less than one year to approximately six years.  The weighted-average lease term remaining for these leases is approximately three years.  Certain leases also contain optional extension periods that allow for terms to be extended for up to an additional 10 years.  An early termination option also exists for certain leases, some of which allow for the Company to terminate a lease within one year.  Exercising an early termination option may also result in an early termination penalty depending on the terms of the underlying agreement.  Based on expectations for those agreements with early termination options, there are no leases in which material early termination options are reasonably certain to be exercised by the Company.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:12pt;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;For the three months ended September&#160;30, 2020, and 2019, total costs related to operating leases, including short-term leases, and variable lease payments made for leases with initial lease terms greater than 12 months, were $49.9 million and $107.3 million, respectively.  For the nine months ended September&#160;30, 2020, and 2019, total lease costs were $184.9 million and $422.4 million, respectively.  These totals do not reflect amounts that may be reimbursed by other third parties in the normal course of business, such as non-operating working interest owners.  Components of the Company&#x2019;s total lease cost, whether capitalized or expensed, for the three and nine months ended September&#160;30, 2020, and 2019, consisted of the
