Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Description and Summary of Significant Accounting Policies	(1) Business Description and Summary of Significant Accounting Policies The accompanying condensed consolidated financial statements include the accounts of Xtant Medical Holdings, Inc. (“Xtant”), formerly known as Bacterin International Holdings, Inc., a Delaware corporation, and its wholly owned subsidiaries, Xtant Medical, Inc., a Delaware corporation, Bacterin International, Inc., (“Bacterin”) a Nevada corporation and X-Spine Systems, Inc. (“X-spine”), an Ohio corporation, (Xtant Medical, Bacterin and X-spine are jointly referred to herein as the “Company”). All intercompany balances and transactions have been eliminated in consolidation. Xtant develops, manufactures and markets regenerative orthopedic products for domestic and international markets and fixation devices. Xtant products serve the combined specialized needs of orthopedic and neurological surgeons, including orthobiologics for the promotion of bone healing, implants and instrumentation for the treatment of spinal disease, tissue grafts for the treatment of orthopedic disorders to promote healing following spine, cranial and foot surgeries and the development, manufacturing and sale of medical devices for use in orthopedic spinal surgeries. On July 31, 2015, Xtant acquired all of the outstanding capital stock of X-spine for approximately $ 60 13 4,242,655 The markets in which the Company competes are highly competitive and rapidly changing. Significant technological advances, changes in customer requirements, or the emergence of competitive products with new capabilities or technologies could adversely affect the Company’s operating results. The Company’s business could be harmed by a decline in demand for, or in the prices of, its products or as a result of, among other factors, any change in pricing or distribution methods, increased price competition, changes in government regulations or a failure by the Company to keep up with technological change. Further, a decline in available donors could have an adverse impact on our business. The accompanying interim condensed consolidated financial statements of Xtant for the three and six months ended June 30, 2017 and 2016 are unaudited and are prepared in accordance with accounting principles generally accepted in the United States of America. They do not include all disclosures required by generally accepted accounting principles for annual consolidated financial statements, but in the opinion of management, include all adjustments, consisting only of normal recurring items, necessary for a fair presentation. Interim results are not necessarily indicative of results which may be achieved in the future for the full year ending December 31, 2017. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto which are included in Xtant’s Annual Report on Form 10-K for the year ended December 31, 2016. The accounting policies set forth in those annual consolidated financial statements are the same as the accounting policies utilized in the preparation of these condensed consolidated financial statements, except as modified for appropriate interim consolidated financial statement presentation. The Company has incurred losses since its inception. The terms, conditions and amounts outstanding under the Company’s debt agreements (See Note 7, “Debt” below) raise substantial doubt about the Company’s ability to continue as a going concern. The Company has established a special committee of its board of directors to evaluate restructuring alternatives assist in related negotiations with the Company’s lenders and consider alternatives for raising new capital. The Company also is evaluating various cost-reduction and cash flow improvement measures. However, there can be no assurance that the Company will be successful in these efforts. The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern; however, the above conditions raise substantial doubt about the Company’s ability to do so. The condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result should the Company be unable to continue as a going concern. On May 8, 2017, the Company entered into an agreement (the “CRO Agreement”) with Aurora Management Partners Inc. (“Aurora”). Pursuant to the CRO Agreement, David Baker serves as Chief Restructuring Officer of the Company (the “CRO”) and Wayne Tanner serves as a Deputy Restructuring Officer of the Company. The CRO and Aurora personnel assisting on this engagement report to the special restructuring committee of the board of directors of the Company and provide periodic updates on progress made in fulfilling the scope of services. The term of the agreement will continue until the engagement is completed or earlier if the engagement is terminated by either party. Aurora is paid the hourly rates set forth on Schedule A to the CRO Agreement and is reimbursed for its expenses actually incurred in providing the services. The CRO Agreement may be terminated by either party, in its sole discretion, for any reason and the termination is effective immediately upon the other party’s receipt of written notice of the termination. The Company’s accounts receivable are due from a variety of health care organizations and distributors throughout the world. No single customer accounted for more than 10% of revenue or accounts receivable for the comparable periods. The Company provides for uncollectible amounts when specific credit issues arise. Management’s estimates for uncollectible amounts have been adequate during prior periods, and management believes that all significant credit risks have been identified at June 30, 2017. In the six months ended June 30, 2017, Xtant purchased from Norwood Medical less than 10 14 The preparation of the consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the period. Significant estimates include the carrying amount of property and equipment, goodwill, and intangible assets and liabilities; valuation allowances for trade receivables, inventory, and deferred income tax assets and liabilities; valuation of the warrant derivative liability, inventory, and estimates for the fair value of stock options grants and other equity awards upon which the Company determines stock-based compensation expense. Actual results could differ from those estimates. Long-lived assets, including intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets Goodwill represents the excess of costs over fair value of assets of businesses acquired. Goodwill and intangible assets acquired in a purchase business combination and determined to have indefinite useful lives are not amortized, instead they are tested for impairment at least annually and whenever events or circumstances indicate the carrying amount of such asset may not be recoverable. In its evaluation of goodwill, the Company performs an assessment of qualitative factors to determine if it is more-likely-than-not that goodwill might be impaired and whether it is necessary to perform the two-step goodwill impairment. The Company conducts its annual impairment test on December 31 of each year. Revenue is recognized when all of the following criteria are met: a) the Company has entered into a legally binding agreement with the customer; b) the products or services have been delivered; c) the Company’s fee for providing the products and services is fixed or determinable; and d) collection of the Company’s fee is probable. The Company’s policy is to record revenue net of any applicable sales, use, or excise taxes. If an arrangement includes a right of acceptance or a right to cancel, revenue is recognized when acceptance is received or the right to cancel has expired. The Company ships to certain customers under consignment arrangements whereby the Company’s product is stored by the customer. The customer is required to report the use to the Company and upon such notice, the Company invoices the customer and revenue is recognized when above criteria have been met. Research and development costs, which are principally related to internal costs for the development of new devices and biologics and processes are expensed as incurred. Other income (expense) primarily consists of non-recurring items that are outside of the normal Company’s operations such as other related legal expenses, gain or loss on the sale of fixed assets, restructuring costs and miscellaneous minor adjustments to account balances. Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding. Shares issued during the period and shares reacquired during the period are weighted for the portion of the period that they were outstanding. Diluted net income (loss) per share is computed in a manner consistent with that of basic earnings per share while giving effect to all potentially dilutive common shares outstanding during the period, which include the assumed exercise of stock options and warrants using the treasury stock method. Diluted net loss per share was the same as basic net loss per share for the six months ended June 30, 2017 and 2016, as shares issuable upon the exercise of stock options and warrants were anti-dilutive as a result of the net losses incurred for those periods. Dilutive earnings per share are not reported as their effects of including 7,477,910 1,798,192 The carrying values of financial instruments, including trade accounts receivable, accounts payable, other accrued expenses and long-term debt, approximate their fair values based on terms and related interest rates. The Company follows a framework for measuring fair value. The framework provides a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below: Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets. Level 2: Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. During the six months ended June 30, 2017 and 2016, there was no reclassification in financial assets or liabilities between Level 1, 2 or 3 categories. The following table sets forth by level, within the fair value hierarchy, our liabilities that are measured at fair value on a recurring basis: As of As of June 30, December 31, 2017 2016 Level 1 - - Level 2 - - Level 3 $ 177,380 $ 333,613 The valuation technique used to measure fair value of the warrant liability is based on a lattice valuation model and significant assumptions and inputs determined by us (See Note 9, “Warrants” below). Level 3 Changes The following is a reconciliation of the beginning and ending balances for liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the six months ended June 30, 2017: Balance at January 1, 2017 $ 333,613 Gain recognized in earnings in first quarter of 2017 (170,031) Balance at March 31 , 2017 $ 163,582 Loss recognized in earnings in second quarter of 2017 13,798 Balance at June 30, 2017 $ 177,380 During the six months ended June 30, 2017, the Company did not change any of the valuation techniques used to measure its liabilities at fair value. In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers. The new standard was originally effective for reporting periods beginning after December 15, 2016 and early adoption was not permitted. On August 12, 2015, the FASB approved a one year delay of the effective date to reporting periods beginning after December 15, 2017, while permitting companies to voluntarily adopt the new standard as of the original effective date. The comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. The Company is currently evaluating the impacts of adoption and the implementation approach to be used. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842)

Equity [Abstract]
Equity	(2) Equity In connection with the offering of units pursuant to the subscription rights, referred to as the “Rights Offering,” the Company distributed to holders of its common stock and to holders of its convertible notes, at no charge, non-transferable subscription rights to purchase units. Each unit consisted of one share of common stock and one tradeable warrant representing the right to purchase one share of common stock (“Tradeable Warrants”). On October 31, 2016, the Company entered into a dealer-manager agreement (the “Dealer-Manager Agreement”) with Maxim Group LLC (“Maxim”), to engage Maxim as dealer-manager for the Rights Offering. In the Rights Offering, holders received two subscription rights for each share of common stock, or each share of common stock underlying our convertible notes owned on the record date, October 21, 2016. Subscribers whose subscriptions otherwise would have resulted in their beneficial ownership of more than 4.99 0.01 The Rights Offering closed on November 14, 2016. The units were priced at $ 0.75 3.8 2.5 0.90 After the one-year anniversary of issuance, we may redeem the Tradeable Warrants for $0.01 per Tradeable Warrant if the volume weighted average price of our common stock is above $2.25 for each of 10 consecutive trading days. In connection with the Rights Offering, the Company paid to Maxim a cash fee equal to 7 75,000 Under the terms and subject to the conditions contained in the Dealer-Manager Agreement, the Company agreed not to issue or announce the issuance of any shares of common stock or common stock equivalents until 90 days after the closing date of the Rights Offering, without the consent of Maxim, subject to certain exceptions including a pre-existing agreement, equity awards, conversion of derivative securities and in connection with any acquisitions, partnerships or strategic transactions.

Debt	(7) Debt Convertible Note Indenture On July 31, 2015, we completed an offering of $ 65 6.00 52 3 At any time prior to the close of business on the second business day immediately preceding the maturity date, holders may convert their Notes into shares of Xtant common stock (together with cash in lieu of fractional shares) at an initial conversion rate of 257.5163 1,000 3.88 9.99 We will not adjust the conversion rate for other events, such as for an issuance of our common stock for cash or in connection with an acquisition that may dilute our common stock thereby adversely affecting its market price. In addition, Xtant will, in certain circumstances, increase the conversion rate for holders who convert their Notes in connection with a “make-whole fundamental change” (as defined in the Indenture). No sinking fund is provided for the Notes. Xtant may not redeem the Notes at its option prior to their maturity. If a “fundamental change” (as defined in the Indenture) occurs, holders will have the right, at their option, to require us to repurchase their Notes at a cash price equal to 100 The Notes are Xtant’s senior, unsecured obligations, rank equal in right of payment with its existing and future unsecured indebtedness that is not junior to the Notes, are senior in right of payment to any of its existing and future indebtedness that is expressly subordinated to the Notes, and are effectively subordinated to its existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness. The Notes are structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent Xtant is not a holder thereof) preferred equity, if any, of its subsidiaries. On April 14, 2016, we issued $ 2,238,166 Both the Additional Notes and the Notes bear interest at a rate equal to 6.00 The Additional Notes may be converted into shares of our common stock (together with cash in lieu of fractional shares) at an initial conversion rate of 344.8276 1,000 2.90 On January 17, 2017, the Company entered into securities purchase agreements with Bruce Fund, Inc., Park West Partners International, Limited, Park West Investors Master Fund, Limited, and Telemetry Securities, L.L.C., to satisfy interest obligations that we owed to such parties under $ 16,000,000 843,289 0.5692 On January 17, 2017, the Company entered into a securities purchase agreement and certain related documents with the OrbiMed Purchasers, to satisfy interest obligations that the Company owed to them pursuant to $ 52,000,000 6 1,560,000 0.7589 On January 17, 2017, the Company also entered into a securities purchase agreement and certain related documents with the OrbiMed Purchasers, to satisfy interest obligations that the Company owed to them pursuant to $ 2,238,166 6 67,145 0.7589 July 15, 2021 Effective March 31, 2017, the Company and the OrbiMed Purchasers entered into a waiver letter (the “Indenture Waiver”) of the Indenture.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	(8) Stock-Based Compensation The Amended and Restated Xtant Medical Equity Incentive Plan (the “Plan”) provides for stock awards, including options and performance stock awards, to be granted to employees, consultants, independent contractors, officers and directors. The purpose of the Plan is to enable us to attract, retain and motivate key employees, directors and, on occasion, independent consultants, by providing them with stock options and restricted stock grants. Stock options granted under the Plan may be either incentive stock options to employees, as defined in Section 422A of the Internal Revenue Code of 1986, or non-qualified stock options. The Plan is administered by the compensation committee of our board of directors. Stock options granted under the Plan are generally not transferable, vest in installments over the requisite service period and are exercisable during the stated contractual term of the option only by such optionee. Executives may be awarded an option to purchase common stock outside of the Plan (collectively the “Non-Plan Grants”), as described below. The exercise price of all incentive stock options granted under the Plan must be at least equal to the fair market value of the shares of common stock on the date of the grant. 1,900,000 670,000 Stock compensation expense recognized in the condensed consolidated statements of operations for the six months ended June 30, 2017 and 2016 is based on awards ultimately expected to vest and reflects an estimate of awards that will be forfeited. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. No stock options were issued in the first six months of 2017 or 2016. 2017 2016 Weighted Weighted Average Average Weighted Fair Weighted Fair Average Value at Average Value at Exercise Grant Exercise Grant Shares Price Date Shares Price Date Outstanding at January 1 1,205,913 $ 5.21 $ 2.82 664,081 $ 10.64 $ 5.32 Cancelled or expired (19,334) 11.42 7.91 (101,875) 9.60 4.54 Outstanding at June 30 1,186,579 $ 5.11 $ 2.80 562,206 $ 10.83 $ 5.46 Exercisable at June 30 388,021 $ 11.42 $ 5.67 388,603 $ 12.82 $ 6.20 The aggregate intrinsic value of options outstanding as of June 30, 2017 was zero because the closing price of the stock at June 30, 2017 was less than the strike price of all options outstanding.

Where it is determined that it is likely that we will be unable to realize deferred tax assets, a valuation allowance is established against the portion of the deferred tax asset. Because it cannot be accurately determined when or if we will become profitable, a valuation allowance was provided against the entire deferred income tax asset balance. The Company did not recognize any interest or penalties related to income taxes for the six months ended June 30, 2017 and 2016.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Description	Business Description The accompanying condensed consolidated financial statements include the accounts of Xtant Medical Holdings, Inc. (“Xtant”), formerly known as Bacterin International Holdings, Inc., a Delaware corporation, and its wholly owned subsidiaries, Xtant Medical, Inc., a Delaware corporation, Bacterin International, Inc., (“Bacterin”) a Nevada corporation and X-Spine Systems, Inc. (“X-spine”), an Ohio corporation, (Xtant Medical, Bacterin and X-spine are jointly referred to herein as the “Company”). All intercompany balances and transactions have been eliminated in consolidation. Xtant develops, manufactures and markets regenerative orthopedic products for domestic and international markets and fixation devices. Xtant products serve the combined specialized needs of orthopedic and neurological surgeons, including orthobiologics for the promotion of bone healing, implants and instrumentation for the treatment of spinal disease, tissue grafts for the treatment of orthopedic disorders to promote healing following spine, cranial and foot surgeries and the development, manufacturing and sale of medical devices for use in orthopedic spinal surgeries. On July 31, 2015, Xtant acquired all of the outstanding capital stock of X-spine for approximately $ 60 13 4,242,655 The markets in which the Company competes are highly competitive and rapidly changing. Significant technological advances, changes in customer requirements, or the emergence of competitive products with new capabilities or technologies could adversely affect the Company’s operating results. The Company’s business could be harmed by a decline in demand for, or in the prices of, its products or as a result of, among other factors, any change in pricing or distribution methods, increased price competition, changes in government regulations or a failure by the Company to keep up with technological change. Further, a decline in available donors could have an adverse impact on our business. The accompanying interim condensed consolidated financial statements of Xtant for the three and six months ended June 30, 2017 and 2016 are unaudited and are prepared in accordance with accounting principles generally accepted in the United States of America. They do not include all disclosures required by generally accepted accounting principles for annual consolidated financial statements, but in the opinion of management, include all adjustments, consisting only of normal recurring items, necessary for a fair presentation. Interim results are not necessarily indicative of results which may be achieved in the future for the full year ending December 31, 2017. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto which are included in Xtant’s Annual Report on Form 10-K for the year ended December 31, 2016. The accounting policies set forth in those annual consolidated financial statements are the same as the accounting policies utilized in the preparation of these condensed consolidated financial statements, except as modified for appropriate interim consolidated financial statement presentation.
Going Concern	Going Concern The Company has incurred losses since its inception. The terms, conditions and amounts outstanding under the Company’s debt agreements (See Note 7, “Debt” below) raise substantial doubt about the Company’s ability to continue as a going concern. The Company has established a special committee of its board of directors to evaluate restructuring alternatives assist in related negotiations with the Company’s lenders and consider alternatives for raising new capital. The Company also is evaluating various cost-reduction and cash flow improvement measures. However, there can be no assurance that the Company will be successful in these efforts. The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern; however, the above conditions raise substantial doubt about the Company’s ability to do so. The condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result should the Company be unable to continue as a going concern.
CRO Agreement	CRO Agreement On May 8, 2017, the Company entered into an agreement (the “CRO Agreement”) with Aurora Management Partners Inc. (“Aurora”). Pursuant to the CRO Agreement, David Baker serves as Chief Restructuring Officer of the Company (the “CRO”) and Wayne Tanner serves as a Deputy Restructuring Officer of the Company. The CRO and Aurora personnel assisting on this engagement report to the special restructuring committee of the board of directors of the Company and provide periodic updates on progress made in fulfilling the scope of services. The term of the agreement will continue until the engagement is completed or earlier if the engagement is terminated by either party. Aurora is paid the hourly rates set forth on Schedule A to the CRO Agreement and is reimbursed for its expenses actually incurred in providing the services. The CRO Agreement may be terminated by either party, in its sole discretion, for any reason and the termination is effective immediately upon the other party’s receipt of written notice of the termination.
Concentrations and Credit Risk	Concentrations and Credit Risk The Company’s accounts receivable are due from a variety of health care organizations and distributors throughout the world. No single customer accounted for more than 10% of revenue or accounts receivable for the comparable periods. The Company provides for uncollectible amounts when specific credit issues arise. Management’s estimates for uncollectible amounts have been adequate during prior periods, and management believes that all significant credit risks have been identified at June 30, 2017. In the six months ended June 30, 2017, Xtant purchased from Norwood Medical less than 10 14
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the period. Significant estimates include the carrying amount of property and equipment, goodwill, and intangible assets and liabilities; valuation allowances for trade receivables, inventory, and deferred income tax assets and liabilities; valuation of the warrant derivative liability, inventory, and estimates for the fair value of stock options grants and other equity awards upon which the Company determines stock-based compensation expense. Actual results could differ from those estimates.
Long-Lived Assets	Long-Lived Assets Long-lived assets, including intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets
Goodwill	Goodwill Goodwill represents the excess of costs over fair value of assets of businesses acquired. Goodwill and intangible assets acquired in a purchase business combination and determined to have indefinite useful lives are not amortized, instead they are tested for impairment at least annually and whenever events or circumstances indicate the carrying amount of such asset may not be recoverable. In its evaluation of goodwill, the Company performs an assessment of qualitative factors to determine if it is more-likely-than-not that goodwill might be impaired and whether it is necessary to perform the two-step goodwill impairment. The Company conducts its annual impairment test on December 31 of each year.
Revenue Recognition	Revenue Recognition Revenue is recognized when all of the following criteria are met: a) the Company has entered into a legally binding agreement with the customer; b) the products or services have been delivered; c) the Company’s fee for providing the products and services is fixed or determinable; and d) collection of the Company’s fee is probable. The Company’s policy is to record revenue net of any applicable sales, use, or excise taxes. If an arrangement includes a right of acceptance or a right to cancel, revenue is recognized when acceptance is received or the right to cancel has expired. The Company ships to certain customers under consignment arrangements whereby the Company’s product is stored by the customer. The customer is required to report the use to the Company and upon such notice, the Company invoices the customer and revenue is recognized when above criteria have been met.
Research and Development	Research and Development Research and development costs, which are principally related to internal costs for the development of new devices and biologics and processes are expensed as incurred.
Other Income (Expense)	Other Income (Expense) Other income (expense) primarily consists of non-recurring items that are outside of the normal Company’s operations such as other related legal expenses, gain or loss on the sale of fixed assets, restructuring costs and miscellaneous minor adjustments to account balances.
Net Loss Per Share	Net Loss Per Share Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding. Shares issued during the period and shares reacquired during the period are weighted for the portion of the period that they were outstanding. Diluted net income (loss) per share is computed in a manner consistent with that of basic earnings per share while giving effect to all potentially dilutive common shares outstanding during the period, which include the assumed exercise of stock options and warrants using the treasury stock method. Diluted net loss per share was the same as basic net loss per share for the six months ended June 30, 2017 and 2016, as shares issuable upon the exercise of stock options and warrants were anti-dilutive as a result of the net losses incurred for those periods. Dilutive earnings per share are not reported as their effects of including 7,477,910 1,798,192
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying values of financial instruments, including trade accounts receivable, accounts payable, other accrued expenses and long-term debt, approximate their fair values based on terms and related interest rates. The Company follows a framework for measuring fair value. The framework provides a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below: Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets. Level 2: Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. During the six months ended June 30, 2017 and 2016, there was no reclassification in financial assets or liabilities between Level 1, 2 or 3 categories. The following table sets forth by level, within the fair value hierarchy, our liabilities that are measured at fair value on a recurring basis: As of As of June 30, December 31, 2017 2016 Level 1 - - Level 2 - - Level 3 $ 177,380 $ 333,613 The valuation technique used to measure fair value of the warrant liability is based on a lattice valuation model and significant assumptions and inputs determined by us (See Note 9, “Warrants” below). Level 3 Changes The following is a reconciliation of the beginning and ending balances for liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the six months ended June 30, 2017: Balance at January 1, 2017 $ 333,613 Gain recognized in earnings in first quarter of 2017 (170,031) Balance at March 31 , 2017 $ 163,582 Loss recognized in earnings in second quarter of 2017 13,798 Balance at June 30, 2017 $ 177,380 During the six months ended June 30, 2017, the Company did not change any of the valuation techniques used to measure its liabilities at fair value.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers. The new standard was originally effective for reporting periods beginning after December 15, 2016 and early adoption was not permitted. On August 12, 2015, the FASB approved a one year delay of the effective date to reporting periods beginning after December 15, 2017, while permitting companies to voluntarily adopt the new standard as of the original effective date. The comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. The Company is currently evaluating the impacts of adoption and the implementation approach to be used. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842)
