Liquidity and Capital Resources	2. Liquidity and Capital Resources As of June 30, 2019, the Company had approximately $21.4 million of cash and cash equivalents, $13.8 million of investments available-for-sale, working capital of $33.4 million and an accumulated deficit of $291.4 million. Net cash used in operating activities for the six months ended June 30, 2019 was approximately $15.8 million. On June 20, 2019, the Company closed a public offering of 5,833,334 shares of common stock at a price of $3.00 per share. The aggregate proceeds from this public offering (net of the underwriters’ commissions and offering expenses) were approximately $16.1 million. On July 9, 2019, the underwriters of the public offering partially exercised their over-allotment option and purchased an additional 425,800 shares of common stock at a price of $3.00 per share, which closed on July 11, 2019. The aggregate proceeds from the exercise of the over-allotment option (net of the underwriters’ discount and offering expenses) were approximately $1.2 million. On March 22, 2019, the Company entered into a sales agreement with Cantor Fitzgerald & Co. (the “Agent”), pursuant to which the Company may offer and sell from time to time shares of the Company’s common stock, no par value, through the Agent up to $40,000,000. We are not required to sell any shares at any time during the term of the facility. Our ability to sell common stock under the facility may be limited by several factors including, among other things, the trading volume of our common stock and certain black-out periods that we may impose upon the facility, among other things. Based on the capital raised from the June 20, 2019 offering and proceeds from the partial exercise of the over-allotment option on July 11, 2019, management believes the Company currently has sufficient funds to meet its operating requirements for at least the next twelve months from the date of the filing of this report. The Company will require additional capital to sustain its operations and make the investments it needs to execute upon its longer-term business plan, including the launch of Dialysate Triferic and I.V. Triferic. If the Company is unable to generate sufficient revenue from its existing long-term business plan, the Company will need to obtain additional equity or debt financing. If the Company attempts to obtain additional debt or equity financing, the Company cannot assume that such financing will be available on favorable terms, if at all.

Basis of Presentation, Summary of Significant Accounting Policies and Recent Accounting Pronouncements
Basis of Presentation, Summary of Significant Accounting Policies and Recent Accounting Pronouncements	3. Basis of Presentation, Summary of Significant Accounting Policies and Recent Accounting Pronouncements The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission (“SEC”) and on the same basis as the Company prepares its annual audited consolidated financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of such interim results. The results for the condensed consolidated statement of operations are not necessarily indicative of results to be expected for the year ending December 31, 2019 or for any future interim period. The condensed consolidated balance sheet at June 30, 2019 has been derived from unaudited financial statements; however, it does not include all of the information and notes required by U.S. GAAP for complete financial statements. The condensed consolidated balance sheet at December 31, 2018 has been derived from audited financial statements, however, it does not include all of the information and notes required by U.S. GAAP for complete financial statements. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements for the year ended December 31, 2018 and notes thereto included in the Company’s annual report on Form 10-K filed on March 18, 2019. The accompanying condensed consolidated interim financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to the 2018 financial statements and notes to conform to the 2019 presentation. Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that may affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Significant Accounting Policies With the exception of the adoption of ASU 2016-02 relating to accounting for leases, there have been no material changes in the Company’s significant accounting policies as previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. Leases Effective January 1, 2019, the Company accounts for its leases under Accounting Standards Codification (“ASC”) 842, Leases . Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the consolidated balance sheet as both a right-of-use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right-of-use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset result in straight-line rent expense over the lease term. Variable lease expenses, if any, are recorded when incurred. In calculating the right-of-use asset and lease liability, the Company elects to combine lease and non-lease components. The Company excludes short-term leases having initial terms of 12 months or less from the new guidance as an accounting policy election and recognizes rent expense on a straight-line basis over the lease term. The Company continues to account for leases in the prior period financial statements in accordance with ASC Topic 840. Loss Per Share ASC 260, Earnings Per Share, requires dual presentation of basic and diluted earnings per share (“EPS”), with a reconciliation of the numerator and denominator of the basic EPS computation to the numerator and denominator of the diluted EPS computation. Basic EPS excludes dilution. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that are then sharing in the earnings of the entity. Basic net loss per share of common stock excludes dilution and is computed by dividing the net loss by the weighted average number of shares outstanding during the period. Diluted net loss per share of common stock reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity unless inclusion of such shares would be anti-dilutive. The Company has only incurred losses, therefore, basic and diluted net loss per share is the same. Securities that could potentially dilute net income per share in the future that were not included in the computation of diluted loss per share were as follows: As of June 30, 2019 2018 Options to purchase common stock 8,187,161 6,806,001 Unvested restricted stock awards 146,800 480,000 Unvested restricted stock units 1,658,205 - Warrants to purchase common stock 2,770,781 - 12,762,947 7,286,001 Adoption of Recent Accounting Pronouncements The Company continually assesses any new accounting pronouncements to determine their applicability. When it is determined that a new accounting pronouncement affects the Company’s financial reporting, the Company undertakes a review to determine the consequences of the change to its consolidated financial statements and assures that there are sufficient controls in place to ascertain that the Company’s consolidated financial statements properly reflect the change. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which amended the guidance on accounting for leases. The FASB issued this update to increase transparency and comparability among organizations. This update requires the recognition of lease assets and lease liabilities on the balance sheet and the disclosure of key information about leasing arrangements. The Company adopted this ASU effective January 1, 2019 using the additional (optional) approach by recording a right-of-use asset and a lease liability of approximately $3.5 million. Our adoption of this ASU had no effect on opening retained earnings, and the Company continues to account for leases in the prior period consolidated financial statements under ASC Topic 840. In adopting the new standard, the Company elected to apply the practical expedients regarding identification of leases, lease classification, indirect costs, and the combination of lease and non-lease components. In June 2018, the FASB issued ASU 2018-17, Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for share-based payments granted to nonemployees for goods and services. Under ASU 2018-17, most of the guidance on such payments to nonemployees would be aligned with the requirements for share-based payments granted to employees. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than an entity’s adoption of Topic 606. The Company adopted this new standard on January 1, 2019 and the adoption did not have a material impact on its condensed consolidated financial statements and related disclosures.

Revenue Recognition

Revenue Recognition	6 Months Ended
	Jun. 30, 2019
Revenue Recognition
Revenue Recognition	4. Revenue Recognition The Company recognizes revenue under ASC 606, Revenue from Contracts with Customers. The core principle of the new revenue standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle: · Step 1: Identify the contract with the customer · Step 2: Identify the performance obligations in the contract · Step 3: Determine the transaction price · Step 4: Allocate the transaction price to the performance obligations in the contract · Step 5: Recognize revenue when the company satisfies a performance obligation Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by us from a customer, are excluded from revenue. Shipping and handling costs associated with outbound freight related to contracts with customers are accounted for as a fulfillment cost and are included in cost of sales when control of the goods transfers to the customer. Nature of goods and services The following is a description of principal activities from which the Company generates its revenue. Product sales – The Company accounts for individual products and services separately if they are distinct (i.e., if a product or service is separately identifiable from other items and if a customer can benefit from it on its own or with other resources that are readily available to the customer). The consideration, including any discounts, is allocated between separate products and services based on their stand-alone selling prices. The stand-alone selling prices are determined based on the cost plus margin approach. Drug and dialysis concentrate products are sold directly to dialysis clinics and to wholesale distributors in both domestic and international markets. Distribution and license agreements for which upfront fees are received are evaluated upon execution or modification of the agreement to determine if the agreement creates a separate performance obligation from the underlying product sales. For all existing distribution and license agreements, the distribution and license agreement is not a distinct performance obligation from the product sales. In instances where regulatory approval of the product has not been established and the Company does not have sufficient experience with the foreign regulatory body to conclude that regulatory approval is probable, the revenue for the performance obligation is recognized over the term of the license agreement (over time recognition). Conversely, when regulatory approval already exists or is probable, revenue is recognized at the point in time that control of the product transfers to the customer. The Company received upfront fees under two distribution and license agreements that have been deferred as a contract liability. The amounts received from Wanbang Biopharmaceuticals Co., Ltd. (“Wanbang”) are recognized as revenue over the estimated term of the distribution and license agreement as regulatory approval was not received and the Company did not have sufficient experience in China to determine that regulatory approval was probable as of the execution of the agreement. The amounts received from Baxter Healthcare Corporation (“Baxter”), are recognized as revenue at the point in time that the estimated product sales under the agreement occur. For the business under the Company’s distribution agreement with Baxter (the “Baxter Agreement”), and for the majority of the Company’s international customers, the Company recognizes revenue at the shipping point, which is generally the Company’s plant or warehouse. For other business, the Company recognizes revenue based on when the customer takes control or receipt of the product. The amount of revenue recognized is based on the purchase order less returns and adjusted for any rebates, discounts, chargebacks or other amounts paid to customers. There were no such adjustments for the periods reported. Customers typically pay for the product based on customary business practices with payment terms averaging 30 days, while distributor payment terms average 45 days. Disaggregation of revenue Revenue is disaggregated by primary geographical market, major product line, and timing of revenue recognition.

The Company applies the practical expedient in paragraph 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one year or less. The Baxter Agreement includes minimum commitments of product sales over the duration of the agreement. Unfulfilled performance obligations related to the Baxter Agreement are product sales of $10.1 million, which will be amortized through expiration of the agreement on October 2, 2024.

Revenue Recognition
Deferred Revenue	10. Deferred Revenue In October of 2014, the Company entered into a 10 year distribution agreement with Baxter and received an upfront fee of $20 million. The upfront fee was recorded as deferred revenue and is being recognized based on the proportion of product shipments to Baxter in each period, compared with total expected sales volume over the term of the Baxter Agreement. The Company recognized revenue of approximately $0.5 million and $1.0 million during the three and six months ended June 30, 2019 and 2018, respectively. Deferred revenue related to the Baxter Agreement totaled $10.1 million as of June 30, 2019 and $11.1 million as of December 31, 2018. If a “Refund Trigger Event” occurs, we would be obligated to repay a portion of the upfront fee and any paid portion of the facility fee. In the event of a Refund Trigger Event occurring from January 1, 2019 to December 31, 2021, Baxter would be eligible for a 25% refund of the Agreement’s Upfront Payment. In addition, if Baxter terminates the Agreement because Baxter has been enjoined by a court of competent jurisdiction from selling in the United States any product covered by the Baxter Agreement due to a claim of intellectual property infringement or misappropriation relating to such product prior to the end of 2019, Baxter would be eligible for a partial refund of $6.6 million. In no event would more than one refund be required to be paid.

The Company shall also pay to Charak a percentage of any sublicense income received during the term of the TPN Agreement, which amount shall not be less than a minimum royalty on net sales of the licensed products by the sub-licensee in jurisdictions where there exists a valid claim, on a country-by-country basis, and not be less than a lower rate of the net sales of the licensed products by the sub-licensee in jurisdictions where there exists no valid claim, on a country-by-country basis. The transaction was accounted for as an asset acquisition pursuant to ASU 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business, as the majority of the fair value of the assets acquired was concentrated in a group of similar assets, and the acquired assets did not have outputs or employees. The assets acquired under the MSA include a license of SFP. Because SFP has not yet received regulatory approval, the $1.1 million purchase price paid and accrued for these assets has been expensed in the Company’s statement of operations for the year ended December 31, 2018. In addition, the potential milestone payments are not yet considered probable, and no milestone payments have been accrued at June 30, 2019.

Settlement Agreement	15. Settlement Agreement On August 7, 2018, the Company entered into a confidential settlement agreement and mutual release (the “Settlement Agreement”) with its former CEO, former CFO and a former and then current director. For more details see Note 10 in Form 10-K filed on March 18, 2019. This resulted in a net settlement expense of approximately $1.0 million for the six month ended June 30, 2018. On August 7, 2019, the Company entered into a settlement agreement relating to the class action lawsuits described below. This resulted in a settlement expense of approximately $0.4 million for the six months ended June 30, 2019. See note 16 below for further details. The settlement is subject to court review and approval.

Commitments and Contingencies	16. Commitments and Contingencies Litigation SEC Investigation As a follow up to certain prior inquiries, the Company received a subpoena from the SEC during the Company’s quarter ended September 30, 2018 requesting, among other things, certain information and documents relating to the status of the Company’s request to the Centers for Medicare & Medicaid Services (“CMS”) for separate reimbursement status for Dialysate Triferic, the Company’s reserving methodology for expiring Triferic inventory, and the basis for the Board’s termination of the former CEO and CFO. The Company is cooperating with the SEC and is responding to the SEC’s requests for documents and information. Shareholder Class Action Lawsuits On July 27, 2018, Plaintiff Ah Kit Too filed a putative class action lawsuit in the United States District Court in the Eastern District of New York against the Company and former officers, Robert Chioini and Thomas Klema. The complaint is a federal securities class action purportedly brought on behalf of a class consisting of all persons and entities, other than Defendants, who purchased or otherwise acquired the publicly traded securities of the Company between March 16, 2018 and June 26, 2018. The Complaint alleges that the Company and Messrs. Chioini and Klema violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the “Exchange Act”). Specifically, the Complaint alleges that defendants filed reports with the Securities and Exchange Commission that contained purported inaccurate and misleading statements regarding the potential for the Company’s drug, Triferic, to quality for separate reimbursement status by the Centers for Medicare and Medicaid Services. On September 4, 2018, Plaintiff Robert Spock filed a similar putative class action lawsuit in the United States District Court in the Eastern District of New York against the Company and Messrs. Chioini and Klema. The Spock complaint is a federal securities class action purportedly brought on behalf of a class consisting of persons who purchased the Company’s securities between November 8, 2017 and June 26, 2018. This complaint alleges that the Company and Messrs. Chioini and Klema violated the Exchange Act in that the Company was aware the Centers for Medicare and Medicaid Services would not pursue the Company’s proposal for separate reimbursement for Triferic; misstated reserves in the Company’s quarterly report for the first quarter of 2018; had a material weakness its internal controls over financial reporting, which rendered those controls ineffective; Mr. Chioini withheld material information regarding Triferic from the Company’s auditor, corporate counsel, and independent directors of the Board; and, as a result of these alleged issues, statements about the Company’s business were materially false and misleading. On September 25, 2018, four Company stockholders filed motions to appoint lead plaintiffs, lead counsel, and to consolidate the Ah Kit Too v. Rockwell securities class action with the Spock v. Rockwell securities class action. On October 10, 2018, the court issued an order consolidating the two actions, appointing co-lead plaintiffs and co-lead counsel. On December 10, 2018, lead Plaintiffs filed a consolidated amended complaint, which included the same allegations as the initial complaints and asserted claims on behalf of a putative class consisting of person who purchased the Company’s securities between November 8, 2017 and June 26, 2018, accordingly. On August 7, 2019, all parties to the class action entered into a settlement of the consolidated class action. Pursuant to the terms and conditions of the settlement agreement, the Company will pay the Plaintiffs $3.7 million (the “Settlement Amount’) in exchange for a full release of all liability as to all defendants. Of the Settlement Amount, the Company will be contributing approximately $0.4 million, which represents the remaining retention amount under the Company’s director and officer liability insurance policy. The remainder of the settlement amount will be funded by the Company’s director and officer insurance policy. The settlement is subject to court review and approval. Shareholder Derivative Actions Two verified stockholder derivative complaints (the “Derivative Complaints”) entitled LeClair v Rockwell Medical, Inc., and Post v Rockwell Medical, Inc. were filed in the United States District Court in the Eastern District of New York, purportedly on behalf of the Company (as nominal defendant) and against certain of the Company’s current and former directors (the “Individual Defendants”). The Derivative Complaints assert causes of actions against the Individual Defendants for breach of fiduciary duty, waste of corporate assets, and unjust enrichment. The Derivative Complaints allege the Individual Defendants breached duties by, among other things, permitting alleged misstatements to be made in public filings regarding the status of separate reimbursement for Triferic from CMS, the adequacy of Rockwell’s reserves, and the adequacy of Rockwell’s internal controls. These cases are at an early stage, and the Company anticipates filing a motion to dismiss the action. The Company has tendered the above shareholder derivative actions to its D&O insurance carrier(s) for defense and indemnity under its applicable insurance policies. The Company maintains a $1.0 million self-insured retention under the applicable insurance policies, which will be exhausted upon payment of the Company’s share of the Settlement Amount from the settlement of the class action described above. The Company also has received requests from shareholders to investigate issues relating in part to allegations raised in the securities and derivative lawsuits. The Audit Committee of the Board of Directors engaged independent counsel to investigate these issues. The investigation concluded, among other things that there was no merit to the claims raised in the shareholder requests and the investigation has been concluded.

SUBSEQUENT EVENTS
Subsequent Events	17. Subsequent Events Stock Purchase Agreement On July 9, 2019, the Company issued and sold a total of 425,880 shares of common stock to the underwriters of the Company’s June 17, 2019 underwritten stock offering. The shares sold to the underwriters were issued upon the partial exercise of the underwriters’ overallotment option. The Company received total offering proceeds from the exercise of the over-allotment option (net of underwriting commissions and offering fees) of approximately $1.2 million. I.V. Triferic NDA Acceptance for Filing On August 2, 2019, the Company received notice from the FDA that the Company’s NDA for I.V. Triferic, which was submitted in May, has been accepted for filing, with a Prescription Drug User Fee Act (“PDUFA”) date of March 28, 2020. Amendment to Product Purchase Agreement On August 1, 2019, the Company executed a Products Purchase Agreement (the “Purchase Agreement”) with DaVita Inc. (“DaVita”), with such agreement effective as of July 1, 2019. The Purchase Agreement supersedes and replaces that certain First Amended and Restated Products Purchase Agreement, effective as of May 8, 2013 (as subsequently amended) by and between the Company and DaVita, which agreement expired effective as of July 31, 2019 (the “Prior Agreement”). Pursuant to the Purchase Agreement, the Company will supply certain DaVita dialysis centers with dialysis acid concentrate (i.e., CitraPure® (Liquid and Dry Acid), Dri-Sate® Dry Acid or RenalPure® Liquid Acid) and bicarbonate (i.e., RenalPure® Bicarbonate Powder or Sterilyte® Liquid Bicarbonate) through December 31, 2023 (the “Initial Term”), subject to certain terms and conditions. The Purchase Agreement provides for an increase in the product sale prices relative to the prices charged for these products under the Prior Agreement. If, upon expiration of the Initial Term, the parties have not completed an extension or a new purchase agreement, the Purchase Agreement will continue in effect until terminated by either party with 90 days written notice or until the completion of an extension or new purchase agreement. Centers for Medicare & Medicaid Services (“CMS”) preliminary proposed rule On July 29, 2019, CMS issued a preliminary proposed rule that proposes to update payment policies and rates under the End-Stage Renal Disease (“ESRD”) Prospective Payment System for renal dialysis services furnished to beneficiaries on or after January 1, 2020 (the “Proposed Rules”). The Proposed Rules contain certain proposed revisions to the eligibility requirements for the CMS Transitional Drug Add-on Payment Adjustment (“TDAPA”) program, which has the potential to provide two years of add-on reimbursement for certain qualifying new drugs. Under the proposed revisions to the TDAPA rules, if finalized, ESRD drugs approved by the FDA under the following types of NDAs would be ineligible for TDAPA, effective as of January 1, 2020: (a) NDA Types 3, 5, 7 and 8, (b) NDA Type 3 in combination with NDA Type 2 or NDA Type 4, (c) NDA Type 5 in combination with NDA Type 2, or (d) NDA Type 9, when the “parent NDA” is NDA Type 3, 5, 7 or 8. As previously disclosed, the Company has filed an NDA for the intravenous formulation of Triferic. The FDA has not informed the Company what the classification will be for the I.V. Triferic NDA, although the two prior Triferic NDAs that have been approved were Types 3 and 5. If the I.V. Triferic NDA is classified as either of those Types, or any of the other excluded NDA Types listed in the Proposed Rules, the Company believes that it could be adversely impacted by the Proposed Rules, because it would not be eligible for reimbursement under the Proposed Rules relating to CMS’ TDAPA program. The Company previously disclosed projections for the overall peak Triferic market opportunity in the United States have been based on an assumed market price for I.V. Triferic that is within the CMS reimbursement bundle payment system and not a sustained, higher price based on TDAPA eligibility. CMS is accepting comments on the Proposed Rules through September 27, 2019. Rockwell plans to vigorously oppose this change in the TDAPA eligibility requirements. The Company is currently assessing the impact the Proposed Rules would have on current inventory valuations and stock compensation arrangements if such proposed rule would be finalized and the type of classification for the I.V. Triferic NDA was included.

Basis of Presentation, Summary of Significant Accounting Policies and Recent Accounting Pronouncements
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission (“SEC”) and on the same basis as the Company prepares its annual audited consolidated financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of such interim results. The results for the condensed consolidated statement of operations are not necessarily indicative of results to be expected for the year ending December 31, 2019 or for any future interim period. The condensed consolidated balance sheet at June 30, 2019 has been derived from unaudited financial statements; however, it does not include all of the information and notes required by U.S. GAAP for complete financial statements. The condensed consolidated balance sheet at December 31, 2018 has been derived from audited financial statements, however, it does not include all of the information and notes required by U.S. GAAP for complete financial statements. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements for the year ended December 31, 2018 and notes thereto included in the Company’s annual report on Form 10-K filed on March 18, 2019. The accompanying condensed consolidated interim financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to the 2018 financial statements and notes to conform to the 2019 presentation.
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that may affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of expenses during the reporting period. Actual results could differ from those estimates.
Leases	Leases Effective January 1, 2019, the Company accounts for its leases under Accounting Standards Codification (“ASC”) 842, Leases . Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the consolidated balance sheet as both a right-of-use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right-of-use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset result in straight-line rent expense over the lease term. Variable lease expenses, if any, are recorded when incurred. In calculating the right-of-use asset and lease liability, the Company elects to combine lease and non-lease components. The Company excludes short-term leases having initial terms of 12 months or less from the new guidance as an accounting policy election and recognizes rent expense on a straight-line basis over the lease term. The Company continues to account for leases in the prior period financial statements in accordance with ASC Topic 840.
Loss Per Share	Loss Per Share ASC 260, Earnings Per Share, requires dual presentation of basic and diluted earnings per share (“EPS”), with a reconciliation of the numerator and denominator of the basic EPS computation to the numerator and denominator of the diluted EPS computation. Basic EPS excludes dilution. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that are then sharing in the earnings of the entity. Basic net loss per share of common stock excludes dilution and is computed by dividing the net loss by the weighted average number of shares outstanding during the period. Diluted net loss per share of common stock reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity unless inclusion of such shares would be anti-dilutive. The Company has only incurred losses, therefore, basic and diluted net loss per share is the same. Securities that could potentially dilute net income per share in the future that were not included in the computation of diluted loss per share were as follows: As of June 30, 2019 2018 Options to purchase common stock 8,187,161 6,806,001 Unvested restricted stock awards 146,800 480,000 Unvested restricted stock units 1,658,205 - Warrants to purchase common stock 2,770,781 - 12,762,947 7,286,001
Adoption of Recent Accounting Pronouncements	Adoption of Recent Accounting Pronouncements The Company continually assesses any new accounting pronouncements to determine their applicability. When it is determined that a new accounting pronouncement affects the Company’s financial reporting, the Company undertakes a review to determine the consequences of the change to its consolidated financial statements and assures that there are sufficient controls in place to ascertain that the Company’s consolidated financial statements properly reflect the change. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which amended the guidance on accounting for leases. The FASB issued this update to increase transparency and comparability among organizations. This update requires the recognition of lease assets and lease liabilities on the balance sheet and the disclosure of key information about leasing arrangements. The Company adopted this ASU effective January 1, 2019 using the additional (optional) approach by recording a right-of-use asset and a lease liability of approximately $3.5 million. Our adoption of this ASU had no effect on opening retained earnings, and the Company continues to account for leases in the prior period consolidated financial statements under ASC Topic 840. In adopting the new standard, the Company elected to apply the practical expedients regarding identification of leases, lease classification, indirect costs, and the combination of lease and non-lease components. In June 2018, the FASB issued ASU 2018-17, Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for share-based payments granted to nonemployees for goods and services. Under ASU 2018-17, most of the guidance on such payments to nonemployees would be aligned with the requirements for share-based payments granted to employees. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than an entity’s adoption of Topic 606. The Company adopted this new standard on January 1, 2019 and the adoption did not have a material impact on its condensed consolidated financial statements and related disclosures.
