Basis of Presentation, Organization and Going Concern	1 BASIS OF PRESENTATION, ORGANIZATION AND GOING CONCERN Basis of presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Royal Energy Resources, Inc. (the “Company,” “Royal,” “we,” or “our” ) and its wholly owned subsidiaries Rhino GP LLC (“Rhino GP” or General Partner), Blaze Minerals, LLC (“Blaze”), a West Virginia limited liability company, and Blue Grove Coal, LLC (“Blue Grove”), a West Virginia limited liability company, and its majority owned subsidiary Rhino Resource Partners, LP (“Rhino” or the “Partnership”)(OTCQB:RHNO), a Delaware limited partnership. Rhino GP is the general partner of Rhino. All significant intercompany balances and transactions have been eliminated in consolidation. Unaudited Interim Financial Information The results of operations for the three months ended March 31, 2017 are not necessarily indicative of the results to be expected for the entire year. Organization and nature of business Royal is a Delaware corporation which was incorporated on March 22, 1999, under the name Webmarketing, Inc. On July 7, 2004, the Company revived its charter and changed its name to World Marketing, Inc. In December 2007 the Company changed its name to Royal Energy Resources, Inc. Since 2007, the Company pursued gold, silver, copper and rare earth metal mining concessions in Romania and mining leases in the United States. Commencing in January 2015, the Company began a series of transactions to sell all of its existing assets, undergo a change in ownership control and management and repurpose itself as a North American energy recovery company, planning to purchase a group of synergistic, long-lived energy assets, but taking advantage of favorable valuations for mergers and acquisitions in the current energy markets. On April 13, 2015, the Company executed an agreement for the first acquisition in furtherance of its change in principal operations. Blaze Minerals is the owner of 40,976 net acres of coal and coalbed methane mineral interest in 22 counties across West Virginia. Blue Grove is a licensed mine operator based in McDowell County, West Virginia and is currently under contract to operate a mine owned by GS Energy, LLC. As discussed further below, Royal obtained control of, and a majority limited partner interest, in Rhino on March 17, 2016. Rhino was formed on April 19, 2010 to acquire Rhino Energy LLC (the “Operating Company”). The Operating Company and its wholly owned subsidiaries produce and market coal from surface and underground mines in Illinois, Kentucky, Ohio, West Virginia, and Utah. The majority of Rhino’s sales are made to domestic utilities and other coal-related organizations in the United States. Royal Energy Resources, Inc. Acquisition of Rhino On January 21, 2016, a definitive agreement (“Definitive Agreement”) was completed between Royal and Wexford Capital LP and certain of its affiliates (collectively, “Wexford”) whereby Royal acquired 676,912 issued and outstanding common units of Rhino previously owned by Wexford for $3.5 million. The Definitive Agreement also included a commitment by Royal to acquire within sixty days from the date of the Definitive Agreement all of the issued and outstanding membership interests of Rhino GP, the general partner of Rhino, as well as 945,526 issued and outstanding subordinated units of the Partnership owned by Wexford for $1.0 million. On March 17, 2016, Royal completed the acquisition of all of the issued and outstanding membership interests of the General Partner, as well as 945,526 issued and outstanding subordinated units from Wexford. Royal obtained control of, and a majority limited partner interest, in the Partnership with the completion of this transaction. On March 21, 2016, Royal and the Partnership entered into a securities purchase agreement (the “Securities Purchase Agreement”) pursuant to which the Partnership issued 6,000,000 common units to Royal in a private placement at $1.50 per common unit for an aggregate purchase price of $9.0 million. Royal paid the Partnership $2.0 million in cash and delivered a promissory note payable to Rhino in the amount of $7.0 million (the “Rhino Promissory Note”). The promissory note was payable in three installments: (i) $3.0 million on July 31, 2016; (ii) $2.0 million on or before September 30, 2016 and (iii) $2.0 million on or before December 31, 2016. On December 30, 2016, the Partnership modified the Securities Purchase Agreement with Royal for the final $2.0 million payment due on or before December 31, 2016 to extend the due date to December 31, 2018. See discussion below. As a result of these transactions, Rhino became a majority-owned subsidiary of Royal. Option Agreement-Armstrong Energy On December 30, 2016, the Partnership entered into an option agreement (the “Option Agreement”) with Royal, Rhino Resources Partners Holdings, LLC (“Rhino Holdings”), an entity wholly owned by certain investment partnerships managed by Yorktown Partners LLC (“Yorktown”), and the General Partner. Upon execution of the Option Agreement, the Partnership received an option (the “Call Option”) from Rhino Holdings to acquire substantially all of the outstanding common stock of Armstrong Energy, Inc. (“Armstrong Energy”) that is currently owned by investment partnerships managed by Yorktown, which currently represent approximately 97% of the outstanding common stock of Armstrong Energy. The Option Agreement stipulates that the Partnership can exercise the Call Option no earlier than January 1, 2018 and no later than December 31, 2019. In exchange for Rhino Holdings granting the Partnership the Call Option, the Partnership issued 5.0 million common units, representing limited partner interests in the Partnership (the “Call Option Premium Units”) to Rhino Holdings upon the execution of the Option Agreement. The Option Agreement stipulates the Partnership can exercise the Call Option and purchase the common stock of Armstrong Energy in exchange for a number of common units to be issued to Rhino Holdings, which when added with the Call Option Premium Units, will result in Rhino Holdings owning 51% of the fully diluted common units of the Partnership. The purchase of Armstrong Energy through the exercise of the Call Option would also require Royal to transfer a 51% ownership interest in the General Partner to Rhino Holdings. The Partnership’s ability to exercise the Call Option is conditioned upon (i) sixty (60) days having passed since the entry by Armstrong Energy into an agreement with its bondholders to restructure its bonds and (ii) the amendment of the Partnership’s revolving credit facility to permit the acquisition of Armstrong Energy. The percentage ownership of Armstrong Energy represented by the Armstrong shares as of the date the Call Option is exercised is subject to dilution based upon the terms under which Armstrong Energy restructures its indebtedness, the terms of which have not been determined yet. The Option Agreement also contains an option (the “Put Option”) granted by the Partnership to Rhino Holdings whereby Rhino Holdings has the right, but not the obligation, to cause the Partnership to purchase substantially all of the outstanding common stock of Armstrong Energy from Rhino Holdings under the same terms and conditions discussed above for the Call Option. The exercise of the Put Option is dependent upon (i) the entry by Armstrong Energy into an agreement with its bondholders to restructure its bonds and (ii) the termination and repayment of any outstanding balance under the Partnership’s revolving credit facility. In the event either the Partnership or Rhino GP fail to perform their obligations in the event Rhino Holdings exercises the Put Option, then Rhino Holdings and the Partnership each have the right to terminate the Option Agreement, in which event no party thereto shall have any liability to any other party under the Option Agreement, although Rhino Holdings shall be allowed to retain the Call Option Premium Units. The Option Agreement contains customary covenants, representations and warranties and indemnification obligations for losses arising from the inaccuracy of representations or warranties or breaches of covenants contained in the Option Agreement, the Seventh Amendment and the GP Amendment. Upon the request by Rhino Holdings, we will also enter into a registration rights agreement that provides Rhino Holdings with the right to demand two shelf registration statements and registration statements on Form S-1, as well as piggyback registration rights for as long as Rhino Holdings owns at least 10% of the outstanding common units. Series A Preferred Unit Purchase Agreement On December 30, 2016, the Partnership entered into a Series A Preferred Unit Purchase Agreement (the “Preferred Unit Agreement”) with Weston Energy LLC (“Weston”), an entity wholly owned by certain investment partnerships managed by Yorktown, and Royal. Under the Preferred Unit Agreement, Weston and Royal agreed to purchase 1,300,000 and 200,000, respectively, of Series A preferred units representing limited partner interests in the Partnership (“Series A Preferred Units”) at a price of $10.00 per Series A preferred unit. The Series A preferred units have the preferences, rights and obligations set forth in the Fourth Amended and Restated Agreement of Limited Partnership of the Partnership, Weston and Royal paid cash of $11.0 million and $2.0 million, respectively, to the Partnership and Weston assigned to the Partnership a $2.0 million note receivable from Royal originally dated September 30, 2016 (the “Weston Promissory Note”). The Preferred Unit Agreement contains customary representations, warrants and covenants, which include among other things, that, for as long as the Series A preferred units are outstanding, the Partnership will cause CAM Mining, LLC (“CAM Mining”), which comprises the partnership’s Central Appalachia segment, to conduct its business in the ordinary course consistent with past practice and use reasonable best efforts to maintain and preserve intact its current organization, business and franchise and to preserve the rights, franchises, goodwill and relationships of its employees, customers, lenders, suppliers, regulators and others having business relationships with CAM Mining. The Preferred Unit Agreement stipulates that upon the request of the holder of the majority of the Partnership’s common units following their conversion from Series A preferred units, as outlined in the Amended and Restated Partnership Agreement, the Partnership will enter into a registration rights agreement with such holder. Such majority holder has the right to demand two shelf registration statements and registration statements on Form S-1, as well as piggyback registration rights. Fourth Amended and Restated Agreement of Limited Partnership of Rhino Resource Partners LP On December 30, 2016, Rhino GP entered into the Fourth Amended and Restated Agreement of Limited Partnership of the Partnership (“Amended and Restated Partnership Agreement”) to create, authorize and issue the Series A Preferred Units. The Series A preferred units are a new class of equity security that rank senior to all classes or series of equity securities of the Partnership with respect to distribution rights and rights upon liquidation. The holders of the Series A preferred units shall be entitled to receive annual distributions equal to the greater of (i) 50% of the CAM Mining free cash flow (as defined below) and (ii) an amount equal to the number of outstanding Series A preferred units multiplied by $0.80. “CAM Mining free cash flow” is defined in the Amended and Restated Partnership Agreement as (i) the total revenue of the Partnership’s Central Appalachia business segment, minus (ii) the cost of operations (exclusive of depreciation, depletion and amortization) for the Partnership’s Central Appalachia business segment, minus (iii) an amount equal to $6.50, multiplied by the aggregate number of met coal and steam coal tons sold by the Partnership from its Central Appalachia business segment. If the Partnership fails to pay any or all of the distributions in respect of the Series A preferred units, such deficiency will accrue until paid in full and the Partnership will not be permitted to pay any distributions on its partnership interests that rank junior to the Series A preferred units, including its common units. The Series A preferred units will be liquidated in accordance with their capital accounts and upon liquidation will be entitled to distributions of property and cash in accordance with the balances of their capital accounts prior to such distributions to equity securities that rank junior to the Series A preferred units. The Series A preferred units will vote on an as-converted basis with the common units, and the Partnership will be restricted from taking certain actions without the consent of the holders of a majority of the Series A preferred units, including: (i) the issuance of additional Series A preferred units, or securities that rank senior or equal to the Series A preferred units; (ii) the sale or transfer of CAM Mining or a material portion of its assets; (iii) the repurchase of common units, or the issuance of rights or warrants to holders of common units entitling them to purchase common units at less than fair market value; (iv) consummation of a spin off; (v) the incurrence, assumption or guaranty indebtedness for borrowed money in excess of $50.0 million except indebtedness relating to entities or assets that are acquired by the Partnership or its affiliates that is in existence at the time of such acquisition or (vi) the modification of CAM Mining’s accounting principles or the financial or operational reporting principles of the Partnership’s Central Appalachia business segment, subject to certain exceptions. The Partnership will have the option to convert the outstanding Series A preferred units at any time on or after the time at which the amount of aggregate distributions paid in respect of each Series A preferred unit exceeds $10.00 per unit. Each Series A preferred unit will convert into a number of common units equal to the quotient (the “Series A Conversion Ratio”) of (i) the sum of $10.00 and any unpaid distributions in respect of such Series A Preferred Unit divided by (ii) 75% of the volume-weighted average closing price of the common units for the preceding 90 trading days (the “VWAP”); provided however, that the VWAP will be capped at a minimum of $2.00 and a maximum of $10.00. On December 31, 2021, all outstanding Series A preferred units will convert into common units at the then applicable Series A Conversion Ratio. Debt Classification Reclassifications

Summary of Significant Accounting Policies and General	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND GENERAL Investments in Unconsolidated Affiliates. In December 2012, the Partnership made an initial investment in a new joint venture, Muskie Proppant LLC (“Muskie”), with affiliates of Wexford Capital. In November 2014, the Partnership contributed its investment interest in Muskie to Mammoth Energy Partners LP (“Mammoth”) in return for a limited partner interest in Mammoth. In October 2016, the Partnership contributed its limited partner interests in Mammoth to Mammoth Energy Services, Inc. (NASDAQ: TUSK) (“Mammoth Inc.”) in exchange for 234,300 shares of common stock of Mammoth Inc. For the three months ended March 31, 2017, the Partnership recorded a fair market value adjustment of $1.5 million for the available-for-sale investment based on the market value of the shares at March 31, 2017, which was recorded in Other Comprehensive Income. As of March 31, 2017 and December 31, 2016, the Partnership has recorded its investment in Mammoth Inc. as a short-term asset, which the Partnership has classified as available-for-sale. The Partnership has included its investment in Mammoth Inc. and its prior investment in Muskie in its Other category for segment reporting purposes. In September 2014, the Partnership made an initial investment of $5.0 million in a new joint venture, Sturgeon Acquisitions LLC (“Sturgeon”), with affiliates of Wexford Capital and Gulfport Energy Corporation (NASDAQ: GPOR) (“Gulfport”). The Partnership accounts for the investment in this joint venture and results of operations under the equity method based upon its ownership percentage. The Partnership recorded its proportionate share of the operating loss for this investment for the three months ended March 31, 2017 and 2016 of approximately ($4,000) and ($39,000), respectively. The Partnership has recorded its investment in Sturgeon on the Investment in unconsolidated affiliates line of the Partnership’s consolidated statements of financial position. The Partnership has included its investment in Sturgeon in its Other category for segment reporting purposes. On March 20, 2017, the Partnership executed a contribution agreement to contribute its limited partner interests in Sturgeon to Mammoth Inc.

Acquisitions	3 ACQUISITIONS Acquisition of Rhino GP, LLC and Rhino Resource Partners, LP As discussed in Note 1, the Company acquired Rhino GP and obtained control of, and became a majority limited partner, in Rhino on March 17, 2016. Rhino GP is the general partner of Rhino. Rhino is a diversified energy limited partnership formed in Delaware that is focused on coal and energy related assets and activities, including energy infrastructure investments. Rhino produces, processes and sells high quality coal of various steam and metallurgical grades. Rhino markets its steam coal primarily to electric utility companies as fuel for their steam powered generators. Customers for its metallurgical coal are primarily steel and coke producers who use its coal to produce coke, which is used as a raw material in the steel manufacturing process. Rhino’s business includes investments in oilfield services for independent oil and natural gas producers and land-based drilling contractors in North America. The investments provide completion and production services, including pressure pumping, pressure control, flowback and equipment rental services, and also produce and sell natural sand for hydraulic fracturing. Rhino has a geographically diverse asset base with coal reserves located in Central Appalachia, Northern Appalachia, the Illinois Basin and the Western Bituminous region. As of December 31, 2016, Rhino controlled an estimated 256.9 million tons of proven and probable coal reserves, consisting of an estimated 203.5 million tons of steam coal and an estimated 53.4 million tons of metallurgical coal. In addition, as of December 31, 2016, Rhino controlled an estimated 196.5 million tons of non-reserve coal deposits. At March 31, 2017, the Company’s investment in Rhino consists of $11,250,213 in cash and $4,000,000 in notes payable. The acquisition was completed in three steps as described in Note 1. The fair value of Rhino’s property, plant and equipment was determined by an independent, third-party appraiser that completed their report during the first quarter of 2017. The fair value of the Partnership’s coal properties were based on observable input from market transactions that closely related to the nature of Rhino’s coal properties. The asset retirement obligations of the Partnership were adjusted to fair value based upon current risk adjusted discount rates. The original provisional assets and liabilities have been adjusted as of March 31, 2017 within the one year measurement period. The total income statement impact of these adjustments has been recognized during the three months ended March 31, 2017. The table below reflects the value the assets acquired and the liabilities assumed for the acquisition of Rhino.

Operating results for Rhino for the three months ended March 31, 2017 and 2016 are as follows. Three months ended March 31, 2017 2016 (in thousands) Revenues $ 53,550 $ 39,330 Comprehensive income (loss) $ (563 ) $ (6,018 ) Net loss per share, basic and fully diluted $ (0.22 ) $ (0.33 ) The current quarter’s remeasurement of the acquired net assets of Rhino resulted in the recognition of a deferred income tax liability of $55,529 as of the acquisition date. The recognition of this deferred tax liability has been included in the current quarter’s provision for income taxes. The recognition of the deferred tax liability also reflects future taxable income through the reversals of temporary differences; therefore the current quarter’s tax provision also includes the reversal of a valuation allowance of $7,415 which had been applied to deferred tax assets at December 31, 2016. The remaining components of the provision consists of the deferred tax effects arising from other net income and expense items for the period, including the effects of acquisition remeasurements recognized in the current quarter. The Company has no current income tax expense. Blaze Mining Company, LLC Option Termination and Royalty Agreement On May 29, 2015, the Company entered into an Option Agreement with Blaze Energy Corp. (“Blaze Energy”) to acquire all of the membership units of Blaze Mining Company, LLC (“Blaze Mining”), which is a wholly-owned subsidiary of Blaze. Under the Option Agreement, as amended, the Company had the right to complete the purchase through March 31, 2016 by the issuance of 1,272,858 shares of the Company’s common stock and payment of $250,000 in cash. Blaze Mining controlled operations for and had the right to acquire 100% ownership of Alpheus Coal Impoundment reclamation site in McDowell County, West Virginia under a contract with Gary Partners, LLC, which owned the property. On February 22, 2016, the Company facilitated a series of transactions wherein: (i) Blaze Mining and Blaze Energy entered into an Asset Purchase Agreement to acquire substantially all of the assets of Gary Partners, LLC; (ii) Blaze Mining entered into an Assignment Agreement to assign its rights under the Asset Purchase Agreement to a third party; and (iii) the Company and Blaze Energy entered into an Option Termination Agreement, as amended, whereby the following royalties granted to Blaze Mining under the Assignment Agreement were assigned to the Company: a $1.25 per ton royalty on raw coal or coal refuse mined or removed from the property, and a $1.75 per ton royalty on processed or refined coal or coal refuse mined or removed from the property (the “Royalties”). Pursuant to the Option Termination Agreement, the parties thereby agreed to terminate the Option Agreement by the issuance of 1,750,000 shares of the Company’s common stock to Blaze Energy in consideration for the payment by Blaze Energy of $350,000 to the Company and the assignment by Blaze Mining of the Royalties to the Company. The transactions closed on March 22, 2016. Pursuant to an Advisory Agreement with East Coast Management Group, LLC (“ECMG”), the Company agreed to compensate ECMG $200,000 in cash; $0.175 of the $1.25 royalty on raw coal or coal refuse; and $0.25 of the $1.75 royalty on processed or refined coal for its services in facilitating the Option Termination Agreement. The transaction was initially valued based on the trading price of the Company’s common stock on March 22, 2016 as follows. (thousands) Royalty interests $ 21,113 Cash received 350 Cash paid (200 ) Common stock issued $ 21,263 The Company performed a comprehensive review of its current coal mining operations as well as potential future development projects for the year ended December 31, 2016 to ascertain any potential impairment losses. Since production from this property had not begun at December 31, 2016, the Company engaged a third-party engineer to provide an estimate of fair value. The specialist valued the royalty interests at $4.4 million. Accordingly, the Company recorded an asset impairment loss of $16.7 million in the fourth quarter of 2016.

On March 17, 2016, the Partnership entered into a fourth amendment (the “Fourth Amendment”) of the amended and restated credit agreement. The Fourth Amendment amended the definition of change of control in the amended and restated credit agreement to permit Royal to purchase the membership interests of the General Partner. The Fourth Amendment also eliminated the option to borrow funds utilizing the LIBOR rate plus an applicable margin and establishes the borrowing rate for all borrowings under the facility to be based upon the current PRIME rate plus an applicable margin of 3.50%. On May 13, 2016, the Partnership entered into the Fifth Amendment of the amended and restated credit agreement, which extended the term to July 31, 2017. In July 2016, the Partnership entered into a sixth amendment (the “Sixth Amendment”) of our amended and restated senior secured credit agreement that permitted the sale of Elk Horn that was discussed earlier. The Sixth Amendment further reduced the maximum commitment amount allowed under the credit facility for the additional $1.5 million that is to be received from the Elk Horn sale by $375,000 each quarterly period beginning September 30, 2016 through June 30, 2017. In December 2016, the Partnership entered into a seventh amendment of its amended and restated credit agreement (the “Seventh Amendment”). The Seventh Amendment allows for the issuance of the Series A preferred units as outlined in the Amended and Restated Partnership Agreement. The Seventh Amendment immediately reduced the revolving credit commitments by $11.0 million and provides for additional revolving credit commitment reductions of $2.0 million each on June 30, 2017 and September 30, 2017. The Seventh Amendment further reduces the revolving credit commitments over time on a dollar-for-dollar basis for the net cash proceeds received from any asset sales after the Seventh Amendment date once the aggregate net cash proceeds received exceeds $2.0 million. The Seventh Amendment alters the maximum leverage ratio to 4.0 to 1.0 effective December 31, 2016 through May 31, 2017 and 3.5 to 1.0 from June 30, 2017 through December 31, 2017. The maximum leverage ratio shall be reduced by 0.50 to 1.0 for every $10.0 million of net cash proceeds, in the aggregate, received after the Seventh Amendment date from (i) the issuance of any equity by the Partnership and/or (ii) the disposition of any assets in excess of $2.0 million in the aggregate, provided, however, that in no event will the maximum leverage ratio be reduced below 3.0 to 1.0. The Seventh Amendment alters the minimum consolidated EBITDA, as calculated on a rolling twelve months basis, to $12.5 million from December 31, 2016 through May 31, 2017 and $15.0 million from June 30, 2017 through December 31, 2017. The Seventh Amendment alters the maximum capital expenditures allowed, as calculated on a rolling twelve months basis, to $20.0 million through the expiration of the credit facility. A condition precedent to the effectiveness of the Seventh Amendment is the receipt of the $13.0 million of cash proceeds received by the Partnership from the issuance of the Series A preferred units pursuant to the Preferred Unit Agreement, which was used to repay outstanding borrowings under the revolving credit facility. Per the Seventh Amendment, the receipt of $13.0 million cash proceeds fulfills the required Royal equity contribution, which was a requirement of prior amendments to the credit agreement. On March 23, 2017, the Partnership entered into an eighth amendment (the “Eighth Amendment”) of its amended and restated credit agreement that allows the annual auditor’s report for the years ended December 31, 2016 and 2015 to contain a qualification with respect to the short-term classification of the Partnership’s credit facility balance without creating a default under the credit agreement. As of March 31, 2017 and December 31, 2016, the Partnership was in compliance with respect to all covenants contained in its credit agreement. At March 31, 2017, the Operating Company had borrowed $14.8 million at a variable interest rate of PRIME plus 3.50% (7.50% at March 31, 2017). In addition, the Operating Company had outstanding letters of credit of $26.1 million at a fixed interest rate of 5.00% at March 31, 2017. Based upon a maximum borrowing capacity of 4.00 times a trailing twelve-month EBITDA calculation (as defined in the credit agreement), the Operating Company had not used $7.7 million of the borrowing availability at March 31, 2017.

The Plan is intended to promote the interests of the Partnership by providing to employees, consultants and directors of the General Partner, the Partnership or affiliates of either, incentive compensation awards to encourage superior performance. The LTIP provides for grants of restricted units, unit options, unit appreciation rights, phantom units, unit awards, and other unit-based awards.

Fair Value Disclosures [Abstract]
Fair Value Measurements	18 FAIR VALUE OF FINANCIAL INSTRUMENTS The Company determines the fair value of assets and liabilities based on 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. 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. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s assumptions of what market participants would use. The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below: Level One - Quoted prices for identical instruments in active markets. Level Two - The fair value of the assets and liabilities included in Level 2 are based on standard industry income approach models that use significant observable inputs. Level Three - Unobservable inputs significant to the fair value measurement supported by little or no market activity. In those cases when the inputs used to measure fair value meet the definition of more than one level of the fair value hierarchy, the lowest level input that is significant to the fair value measurement in its totality determines the applicable level in the fair value hierarchy. The book values of cash and cash equivalents, accounts receivable and accounts payable are considered to be representative of their respective fair values because of the immediate short-term maturity of these financial instruments. The fair value of the Partnership’s amended and restated senior secured credit facility was based upon a Level 2 measurement utilizing a market approach, which incorporated market-based interest rate information with credit risks similar to the Partnership. The fair value of the Partnership’s amended and restated senior secured credit facility approximates the carrying value at March 31, 2017. As of March 31, 2017 and December 31, 2016, the Partnership had a recurring fair value measurement relating to its investment in Mammoth, Inc. As discussed in Note 2, in October 2016, the Partnership contributed its limited partner interests in Mammoth to Mammoth, Inc. in exchange for 234,300 shares of common stock of Mammoth, Inc. The common stock of Mammoth, Inc. began trading on the NASDAQ Global Select Market in October 2016 under the ticker symbol TUSK and the Partnership sold 1,953 shares during the initial public offering of Mammoth, Inc. and received proceeds of approximately $27,000. The Partnership’s remaining shares of Mammoth, Inc. are classified as a held-for-sale investment on the Partnership’s unaudited condensed consolidated statements of financial position. Based on the availability of a quoted price, the recurring fair value measurement of the Mammoth, Inc. shares is a Level 2 measurement.
