FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. The forward-looking statements provide our current expectations or forecasts of future events and financial performance and may be identified by the use of forward-looking terminology, including such terms as “believes,” “estimates,” “anticipates,” “expects,” “plans,” “intends,” “may,” “will” or “should” or, in each case, their negative, or other variations or comparable terminology, though the absence of these words does not necessarily mean that a statement is not forward-looking. Forward-looking statements include all matters that are not historical facts and include, without limitation, statements concerning our business strategy, outlook, objectives, future milestones, plans, intentions, goals, and future financial condition, including the period of time during which our existing resources will enable us to fund our operations. Forward-looking statements also include our financial, clinical, manufacturing and distribution plans, and our expectations related our development and potential regulatory plans to secure marketing authorization for AEROSURF^® and other potential future products that we may develop; our expectations, timing and anticipated outcomes of submitting regulatory filings for our products under development; our research and development programs, including planning for development activities, anticipated timing of clinical trials and potential development milestones for our KL4 surfactant pipeline and our Aerosol Delivery System (ADS) based on our capillary aerosol generator technology for delivery of aerosolized medications; plans for the manufacture of drug products, active pharmaceutical ingredients (APIs), materials and medical devices; and plans regarding potential strategic alliances and collaborative arrangements to develop, manufacture and market our products, and other potential strategic transactions.

We intend that all forward-looking statements be subject to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995.  Forward-looking statements are subject to many risks and uncertainties that could cause actual results to differ materially from any future results expressed or implied by the forward-looking statements.  We caution you therefore against relying on any of these forward-looking statements.  They are neither statements of historical fact nor guarantees or assurances of future performance.  Examples of the risks and uncertainties include, but are not limited to:

•

the risk that our AEROSURF phase 2a and 2b clinical trials, which are part of our lead clinical development program, may be interrupted, delayed, or generate inconclusive or non-compelling data, or present an unacceptable benefit/risk profile due to suboptimal efficacy and/or safety profile, which would have a material adverse impact on our business and our ability to continue as a going concern;

•

the risk that we will require significant additional capital to support our research and development activities and operations and have sufficient cash resources to service and repay debt; our ability to raise such capital may be adversely impacted by any delay or inability to complete our AEROSURF phase 2b clinical trial as planned, or if we obtain results from our clinical trial that are not sufficient to support a strategic transaction or equity financing; limitations arising out of our status as a smaller reporting company on our ability to conduct primary offerings under our 2014 Universal Shelf, for our ATM Program or otherwise; the limited number of authorized shares available for issuance under our Amended and Restated Certificate of Incorporation, or failure to secure stockholder approval, if required, for a transaction involving greater than 20% of our outstanding common stock; any failure to comply with The Nasdaq Capital Market (Nasdaq) listing requirements, including with respect to the minimum bid price requirement, minimum market capitalization or minimum stockholders’ equity; and that unfavorable credit and financial markets may adversely affect our ability to fund our activities and that additional equity financings could result in substantial equity dilution;

•

risks relating to our ability to manage our limited resources effectively and timely modify our business strategy as needed to respond to developments in our research and development activities, as well as in our business, our industry and other factors;

 

•

the risk that failure to maintain compliance with either of the minimum market value of outstanding shares ($35 million) or the minimum stockholders’ equity ($2.5 million) Nasdaq listing requirements may result in receipt of a Nasdaq delisting notice; if upon receipt of a delisting notice, we fail to regain compliance within any allowed grace period or other process provided under the Nasdaq listing requirements, our common stock may be delisted and the value of our common stock may decrease;

•

risks related to our efforts to gain regulatory approval in the U.S. and elsewhere for our drug products, medical device and combination drug/device product candidates, including AEROSURF and our lyophilized KL4 surfactant, which is the drug component of AEROSURF and potentially could be developed as a separate surfactant drug product, including that changes in the national or international political and regulatory environment may make it more difficult to gain FDA or other regulatory approval of our drug products, medical device and combination drug/device product candidates;

•

risks relating to the rigorous regulatory approval processes, including pre-filing activities, required for approval of any drug, combination drug/device product or medical device that we may develop, whether independently, with strategic development partners or pursuant to collaboration arrangements, including that the FDA or other regulatory authorities may not file, or may withhold or delay consideration of, any applications that we may submit, the FDA or other regulatory authorities will not be able to agree on matters raised during the regulatory review process and other interactions, or that we may be required to conduct significant additional activities to potentially gain approval of our product candidates, if ever; or that the FDA or other regulatory authorities may not approve our applications or may limit approval of our products to particular indications or impose unanticipated label limitations;

•

the risk that we may be unable to identify and enter into strategic alliances, collaboration agreements or other strategic transactions that would provide capital to support our AEROSURF development activities and resources and expertise to support the registration and commercialization of AEROSURF in markets outside the U.S. and potentially support the development and, if approved, commercialization, of our other potential KL4 surfactant pipeline products;

•

risks relating to the transfer of our manufacturing technology to contract manufacturing organizations (CMOs) and assemblers, and our CMOs’ ability to manufacture our lyophilized KL4 surfactant, which must be processed in an aseptic environment and tested using sophisticated and extensive analytical methodologies and quality control release and stability tests, for our research and development activities and, if approved, commercial applications;

•

risks relating to our and our CMOs’ compliance status or ability to develop and manufacture our ADS and related components for preclinical and clinical studies of our combination drug/device product candidates and, if approved, commercial activities;

•

the risk that we, our CMOs or any of our third-party suppliers, many of which are single-source providers, may encounter problems in manufacturing our KL4 surfactant drug product, the active pharmaceutical ingredients (APIs) used in the manufacture of our KL4 drug product, ADS and related components, and other materials on a timely basis or in an amount sufficient to support our needs;

 

•

risks relating to our pledge of substantially all of our assets to secure our obligations under our loan facility (Deerfield Loan) with affiliates of Deerfield Management Company, L.P., which could make it more difficult for us to secure additional capital to satisfy our obligations and require us to dedicate cash flow to payments for debt service, which would reduce the availability of our cash flow to fund working capital, capital expenditures and other investment; moreover, we may be required to seek the consent of Deerfield to enter into certain strategic transactions;

•

risks that reimbursement and health care reform may adversely affect our ability to secure appropriate funding and reimbursement; or that our products will not be accepted by physicians and others in the medical community; or that market conditions, the competitive landscape or other factors may make it difficult to launch and profitably sell our products;

 

•

the risk that we, our strategic partners or collaborators will be unable to attract and retain key employees, including qualified scientific, professional and other personnel, in a competitive market for skilled personnel, which could have a material adverse effect on our commercial and development activities and our operations;

•

the risks that we may be unable to maintain and protect the patents and licenses related to our products and that other companies may develop competing therapies and/or technologies;

•

the risks that we may become involved in securities, product liability and other litigation and that our insurance may be insufficient to cover costs of damages and defense; and

•

other risks and uncertainties as detailed in “Risk Factors” in our most recent Annual Report on Form 10-K as amended, filed with the Securities and Exchange Commission (SEC) on March 29, 2016, and our other filings with the SEC and any amendments thereto, and in the documents incorporated by reference in this report.

Pharmaceutical, biotechnology and medical technology companies have suffered significant setbacks conducting clinical trials, even after obtaining promising earlier preclinical and clinical data.  Moreover, data obtained from clinical trials are susceptible to varying interpretations, which could delay, limit or prevent regulatory approval.  After gaining approval of a drug product, pharmaceutical and biotechnology companies face considerable challenges in marketing and distributing their products, and may never become profitable.

The forward-looking statements contained in this report or the documents incorporated by reference herein speak only as of their respective dates.  Factors or events that could cause our actual results to differ may emerge from time to time and it is not possible for us to predict them all.  Except to the extent required by applicable laws, rules or regulations, we do not undertake any obligation to publicly update any forward-looking statements or to publicly announce revisions to any of the forward-looking statements, whether as a result of new information, future events or otherwise.

Note 1 – The Company and Description of Business

Windtree Therapeutics, Inc. (referred to as “we,” “us,” or the “Company”) is a biotechnology company focused on developing novel KL4 surfactant therapies for respiratory diseases and other potential applications.  Surfactants are produced naturally in the lung and are essential for normal respiratory function and survival.  Our proprietary technology platform includes a synthetic, peptide-containing surfactant (KL4 surfactant) that is structurally similar to endogenous pulmonary surfactant, and novel drug delivery technologies being developed to enable noninvasive administration of aerosolized KL4 surfactant.  We believe that our proprietary technology platform may make it possible to develop a pipeline of surfactant products to address a variety of respiratory diseases for which there are few or no approved therapies.

Our lead development program, AEROSURF^® (lucinactant for inhalation), is focused on improving the management of respiratory distress syndrome (RDS) in premature infants, a serious respiratory condition that can result in long-term respiratory problems, developmental delay and death.  Premature infants born prior to 37 weeks gestational age may not have fully developed natural lung surfactant and therefore may develop RDS and need surfactant therapy to sustain life.  Higher incidence and severity of RDS are correlated with younger gestational ages; however, RDS can occur at any premature gestational age.  RDS is the most prevalent respiratory disease in the neonatal intensive care unit (NICU).  Surfactant therapy is a life-saving treatment for RDS and the primary therapy to address an underlying surfactant deficiency.  Surfactants currently available in the U.S. are animal-derived and are administered using invasive endotracheal intubation and mechanical ventilation, each of which may result in serious respiratory conditions and other complications.  Intubation is associated with airway trauma and clinical instability that can extend beyond the respiratory system such as increased intracranial pressure and risk for brain injury.  Mechanical ventilation is associated with ventilator-associated lung injury, chronic lung disease and increased risk of infection.  To avoid these risks, many premature infants are initially treated with noninvasive respiratory support, such as nasal continuous positive airway pressure (nCPAP).  Unfortunately, since nCPAP does not address the underlying surfactant deficiency associated with RDS, many premature infants respond poorly to nCPAP (typically within the first 72 hours of life) and may require intubation and delayed surfactant therapy (an outcome referred to as nCPAP failure).  In addition, many premature infants with RDS who receive surfactant therapy as initial therapy are capable of breathing without mechanical ventilation, but require surfactant therapy for RDS.  Because administration of surfactant therapy requires intubation, these infants generally are supported with mechanical ventilation for either a limited or extended period of time.  If surfactant therapy could be administered noninvasively, neonatologists would be able to provide surfactant therapy to these premature infants without exposing them to the risks associated with intubation and mechanical ventilation.

AEROSURF is an investigational combination drug/device product that combines our proprietary KL4 surfactant with our novel aerosol delivery system (ADS), which is based primarily on our capillary aerosol generator technology.  We are developing AEROSURF to enable administration of aerosolized KL4 surfactant to premature infants receiving nCPAP without invasive intubation and mechanical ventilation.  We believe that, if approved, AEROSURF will have the potential to transform the treatment of RDS, allow for earlier treatment of those premature infants who currently receive surfactants later in their course of treatment, decrease the morbidities and complications currently associated with surfactant administration, and reduce the number of premature infants who are subjected to invasive intubation and delayed surfactant therapy as a result of nCPAP failure.  By enabling delivery of our aerosolized KL4 surfactant using noninvasive methods, we believe that AEROSURF, if approved, will address a serious unmet medical need and potentially provide transformative clinical and pharmacoeconomic benefits.

The drug product component of our AEROSURF product candidate is a lyophilized (freeze-dried) dosage form of our KL4 surfactant liquid instillate drug product that was approved by the U.S. Food and Drug Administration (FDA) in 2012 under the name SURFAXIN^® (lucinactant) Intratracheal Suspension for the prevention of RDS in premature infants at high risk for RDS.  In the second quarter of 2015, we determined to cease commercial and manufacturing activities for SURFAXIN to focus our limited resources on advancing the AEROSURF clinical development program and our potential aerosolized KL4 surfactant pipeline.  We believe that gaining the approval of SURFAXIN provided us valuable experience to support the further development of our KL4 surfactant product candidates, beginning with AEROSURF.

Effective February 1, 2016, we announced the appointment of Craig Fraser to serve as our President and Chief Executive Officer.  Upon recommendation of the Nomination and Governance Committee of our Board of Directors Mr. Fraser was also appointed to serve as a member of the Board, effective immediately.  As part of this transition, we initiated a plan to reassess, refocus and rebrand our Company.  Effective April 19, 2016, we changed our name to Windtree Therapeutics, Inc.  Our common stock now trades under the symbol WINT and our new website is windtreetx.com.

 

Note 2 – Basis of Presentation

The accompanying interim unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. for interim financial information in accordance with the instructions to Form 10‑Q.  Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the U.S. for complete consolidated financial statements. All share and per share information in this Quarterly Report related to our common stock has been retroactively restated to reflect the reverse stock split and reduction in authorized shares that was approved by our Board of Directors and stockholders and made effective on January 22, 2016.  In the opinion of management, all adjustments (consisting of normally recurring accruals) considered for fair presentation have been included.  Operating results for the three months ended March 31, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016.  There have been no changes to our critical accounting policies since December 31, 2016.  For a discussion of our accounting policies, see, Note 3, “Accounting Policies and Recent Accounting Pronouncements,” in the Notes to Consolidated Financial Statements in our 2015 Form 10-K, as amended (2015 Form 10-K).  Readers are encouraged to review those disclosures in conjunction with this Quarterly Report on Form 10-Q.

Note 3 – Liquidity Risks and Management’s Plans

The accompanying financial statements have been prepared assuming that we will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business.  In the future, our ability to continue as a going concern is dependent on our ability to raise additional capital to fund our research and development programs and meet our obligations on a timely basis.  To be able to raise additional capital, however, we believe that we will need to successfully complete our ongoing phase 2b clinical trial and release positive top line data in the first quarter of 2017, in accordance with our plan.  If we are unable to complete the trial as planned, or if the results of our clinical trial are inconclusive, or present an unacceptable benefit/risk profile due to suboptimal efficacy and/or safety profile, we may be unable to secure the additional required capital, which could significantly limit our ability to continue as a going concern.  As of March 31, 2016, the financial statements do not include any adjustments relating to recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should we be unable to continue in existence.

To potentially mitigate the risk that we may be unable to continue as a going concern, we plan to pursue all or a combination of potential strategic alliances, collaboration agreements and other strategic transactions (including potentially a merger, acquisition or other corporate transaction).  We also may seek additional capital through public or private equity offerings (including our ATM Program), which could have a dilutive impact on our stockholders and the issuance, or even potential issuance, of shares could have a negative effect on the market price of our common stock.  However, a number of factors in addition to the timing and outcomes of our clinical activities, including whether we will be able to maintain compliance with the Nasdaq listing requirements, limitations on our ability to use our 2014 Universal Shelf and conditions in the broader financial markets, may present significant challenges to accessing the capital markets at a time when we would like or require.  Even if we are able to secure additional capital, such financings may only be available on unattractive terms, or could result in significant dilution of stockholders’ interests.  If none of the foregoing alternatives is available, or if available, we are unable to raise sufficient capital through such transactions, we may be forced to limit or cease our development activities.

We have in the past collaborated with research organizations and universities to assess the potential utility of our KL4 surfactant in studies funded in part through non-dilutive grants issued by U.S. Government-sponsored drug development programs, including grants in support of initiatives related to our AEROSURF clinical program and medical and biodefense-related initiatives under programs that encourage private sector development of medical countermeasures against chemical, biological, radiological, and nuclear terrorism threat agents, and pandemic influenza, and provide a mechanism for federal acquisition of such countermeasures.  Although there can be no assurance, we continue to pursue such funding opportunities and expect that we may qualify for similar programs in the future.

 

Moreover, if we fail in the future to make any required payment under our Deerfield Loan or fail to comply with any commitments contained in the loan documents, Deerfield would be able to declare us in default regarding that indebtedness, which could result in the acceleration of the payment obligations under all or a portion of our indebtedness.  Since we have pledged substantially all of our assets to secure our obligations under the Deerfield Loan, a debt default would enable the lenders to foreclose on our assets securing the debt and could significantly diminish the market value and marketability of our common stock.

Our ability to secure capital under our ATM Program or pursuant to public offerings under our 2014 Universal Shelf is constrained by the value of our equity securities held by nonaffiliated persons and entities (public float), which as of May 10, 2016 is approximately $17.5 million.  Our 2014 Universal Shelf was filed on Form S-3, which limits the size of primary securities offerings conducted by companies that have a public float of less than $75 million to no more than one-third of their public float in any 12-month period.  Accordingly, we are presently able to raise no more than approximately $5.8 million in a primary offering under our 2014 Universal Shelf.  To raise capital, we may be required to seek other forms of transactions, including, for example, under a registration statement on Form S-1, the preparation and maintenance of which would be more time-consuming and costly, or private placements, potentially with registration rights or priced at a discount to the market value of our stock, or other transactions, any of which could result in substantial equity dilution of stockholders’ interests.  In addition, although we have regained compliance with the Minimum Bid Price Requirement of the Nasdaq Listing Rules, we anticipate that we may receive a delisting notice from the Nasdaq Capital Market based on our failure to maintain at least one of the requirements contained in Nasdaq Listing Rule 5550(b), specifically maintaining a minimum market capitalization of at least $35 million or stockholders’ equity of at least $2.5 million.  Failure to regain compliance with at least one these requirements could lead to delisting of our Common Stock and would likely further depress the value of our stock.

In addition, to be able to raise sufficient capital to support our activities in the near term through strategic alliances or other strategic transactions involving the issuance of our capital stock, or through public or private equity offerings, given our current per share market price, we expect to seek approval from our stockholders to increase the number of shares of common stock authorized for issuance under our Amended and Restated Certificate of Incorporation.  In addition, if any such offering were to involve the issuance of common stock in excess of 20% of our outstanding common stock, we may be required under Nasdaq Listing Rules to seek stockholder approval before we can proceed.  There can be no assurance that we would be successful in obtaining such approvals.  Failure to secure the additional capital that we will need, whether from non-dilutive sources or from equity offerings, would have a material adverse impact on our business and our ability to continue as a going concern.

As of March 31, 2016, we had outstanding 2.9 million pre-funded warrants issued in a July 2015 public offering, of which the entire purchase price was pre-paid upon issuance.  Upon exercise of the pre-funded warrants, we would issue the shares to the holders and receive no additional proceeds.  In addition, as of March 31, 2016, there were 36 million shares of common stock and 5 million shares of preferred stock authorized under our Amended and Restated Certificate of Incorporation and approximately 17.0 million shares of common stock and 5 million shares of preferred stock were available for issuance and not otherwise reserved.

Note 4 – Summary of Significant Accounting Policies

The preparation of financial statements, in conformity with accounting principles generally accepted in the U.S., requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Effective February 1, 2016, the Employment Agreement between ourselves and John G. Cooper, our then President and Chief Executive Officer (the Former CEO) was terminated.  In connection therewith, upon execution by the Former CEO of a plenary release in form satisfactory to us, he became entitled under his Employment Agreement to the following severance and other benefits, in addition to any vested benefits under our company plans or policies: (i) a pro rata bonus equal to a percentage of his Annual Bonus Amount (as defined in the Employment Agreement) determined by dividing the aggregate bonuses paid to other contract executives for the year 2016 by the aggregate target bonuses of such other contract executives for 2016, and further prorated for the number of days the Former CEO was employed during 2016, payable at the time that other contract executives are paid bonuses with respect to 2016; (ii) a severance amount equal to the sum of the Former CEO’s base salary then in effect and his Annual Bonus Amount, payable in equal installments through August 1, 2017 (the Severance Period); and (iii) all stock options held by the Former CEO will continue to vest during the Severance Period, and continue to be exercisable for up to 36 months after the date of termination.  From and after the end of the Severance Period, the Former CEO will forfeit all of his unvested stock options in accordance with the terms of the 2011 Plan.  The Former CEO also is subject to non-competition and non-solicitation restrictions for 12 months and 18 months, respectively, after the date of termination under a separate confidentiality agreement.  All of our obligations under the Employment Agreement will cease if at any time during the Severance Period the Former CEO engages in a material breach of the Employment Agreement and fails to cure such breach within five business days after receipt from us of notice of such breach.

 

For the three months ended March 31, 2016, we incurred a severance charge of $1.2 million in selling, general and administrative expense under the terms of the Former CEO’s Employment Agreement, including $0.2 million related to stock option expense for those options that will continue to vest through the Severance Period.  Of the $1.0 million in severance not related to stock-based compensation, $0.1 million was paid during the first quarter of 2016.  The remaining $0.9 million will be paid through August 1, 2017.

In April 2015, we implemented a restructuring plan to voluntarily cease the commercialization of SURFAXIN and focus our resources on the development of our aerosolized KL4 surfactant pipeline for respiratory diseases, beginning with AEROSURF.  As part of the restructuring plan, we ceased manufacturing activities at our manufacturing facility in Totowa, New Jersey (Totowa Facility), which we closed upon the expiration of our lease on June 30, 2015.

The total severance cost for all impacted employees is $2.9 million, of which $1.0 million was accrued as of December 31, 2014 for Totowa employees.  The remaining $1.9 million was charged to expense through the second quarter of 2015 ($1.0 million to research and development expenses and $0.9 million to selling, general and administrative expenses).  We paid $2.6 million and $0.1 million of the severance and retention benefits during 2015 and the first quarter of 2016, respectively.  The remaining $0.2 million will be paid during the second quarter of 2016.

We account for research and development expense by the following categories: (a) product development and manufacturing, (b) medical and regulatory operations, and (c) direct preclinical and clinical programs.   Research and development expense includes personnel, facilities, manufacturing and quality operations, pharmaceutical and device development, research, clinical, regulatory, other preclinical and clinical activities and medical affairs.  Research and development costs are charged to operations as incurred.

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding for the period.  Diluted net loss per common share is computed by giving effect to all potentially dilutive securities outstanding for the period.

For the quarters ended March 31, 2016 and 2015, the number of shares of common stock potentially issuable upon the exercise of stock options and warrants was 9.2 million and 1.7 million shares, respectively.  As of March 31, 2016 and 2015, all potentially dilutive securities were anti-dilutive and therefore have been excluded from the computation of diluted net loss per share.

In accordance with Accounting Standards Codification Topic 260 (ASC 260), Earnings per Share, when calculating diluted net loss per common share, a gain associated with the decrease in the fair value of warrants classified as derivative liabilities results in an adjustment to the net loss; and the dilutive impact of the assumed exercise of these warrants results in an adjustment to the weighted average common shares outstanding.  We utilize the treasury stock method to calculate the dilutive impact of the assumed exercise of warrants classified as derivative liabilities.  For the quarters ended March 31, 2016 and 2015, the effect of the adjustments for warrants classified as derivative liabilities was anti-dilutive.

We do not have any components of other comprehensive income (loss).

 

In August 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern, which is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures.  Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or are available to be issued).  ASU No. 2014-15 provides guidance to an organization’s management, with principles and definitions intended to reduce diversity in the timing and content of disclosures commonly provided by organizations in the footnotes of their financial statements.  ASU No. 2014-15 is effective for annual reporting periods ending after December 15, 2016, and for annual and interim periods thereafter.  While we currently intend to adopt the standard as of December 31, 2016, if this standard had been adopted as of March 31, 2016, management of the Company believes that it would have concluded there is substantial doubt about the Company’s ability to continue as a going concern one year from the date of filing of this Form 10-Q.  See Note 3 for additional information on our liquidity risks and management’s plans.

In February 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-02, amending the accounting for leases in Leases (ASU Topic 482).  This ASU requires lessees to put most leases on their balance sheets but recognize expenses in the income statement in a manner similar to current accounting standards. The ASU is effective for the annual period ending December 31, 2019 and interim periods thereafter. Early adoption is permitted.  Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. We are currently evaluating the effect that ASU 2016-02 will have on our consolidated financial statements and related disclosures.

 

In March 2016, the FASB issued Accounting Standards Update 2016-09, Compensation- Stock Compensation (ASU 2016-09). ASU 2016-09 was issued as part of the FASB Simplification Initiative. This update addresses the income tax effects of stock-based payments and eliminates the windfall pool concept, as all of the tax effects related to stock-based payments will now be recorded at settlement (or expiration) through the income statement. The new guidance also permits entities to make an accounting policy election for the impact of forfeitures on the recognition of expense for stock-based payment awards. Forfeitures can be estimated or recognized when they occur. The standard is effective for annual periods beginning after December 15, 2016 and interim periods within that reporting period. Early adoption is  permitted in any interim or annual period, with any adjustment reflected as of the beginning of the fiscal year of adoption. We are currently evaluating the effect that ASU 2016-09 will have on our consolidated financial statements and related disclosures.

Note 5 – Fair Value of Financial Instruments

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.  The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the last unobservable, as follows:

·

Level 1 – Quoted prices in active markets for identical assets and liabilities.

·

Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

·

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Fair Value on a Recurring Basis

The tables below categorize assets and liabilities measured at fair value on a recurring basis for the periods presented:

 

The tables below summarize the activity of Level 3 inputs measured on a recurring basis for the three months ended March 31, 2016 and 2015:

 

The significant unobservable inputs for a trinomial model used in the fair value measurement of the common stock warrants measured on a recurring basis are the historical volatility of our common stock market price, expected term of the applicable warrants, and the risk-free interest rate based on the U.S. Treasury yield curve in effect at the measurement date.  In addition to the significant unobservable inputs noted above, certain fair value measurements also take into account an assumption of the likelihood and timing of the occurrence of an event that would result in an adjustment to the exercise price in accordance with the anti-dilutive pricing provisions in certain of the warrants.  Any significant increases or decreases in the unobservable inputs, with the exception of the risk-free interest rate, may result in significantly higher or lower fair value measurements.

At March 31, 2016 and December 31, 2015, the estimated fair value of the Deerfield Loan (see, Note 7, “Deerfield Loan”) approximated the carrying value of $25.0 million.  The estimated fair value of the Deerfield Loan is based on discounting the future contractual cash flows to the present value at the valuation date.  This analysis utilizes certain Level 3 unobservable inputs, including current cost of capital.  Considerable judgment is required to interpret market data and to develop estimates of fair value.  The estimates presented are not necessarily indicative of amounts we could realize in a current market exchange.  The use of alternative market assumptions and estimation methodologies could have a material effect on these estimates of fair value.

 

Note 6 – Common Stock Warrant Liability

We account for common stock warrants in accordance with applicable accounting guidance provided in ASC Topic 815, Derivatives and Hedging – Contracts in Entity’s Own Equity (ASC 815), either as derivative liabilities or as equity instruments depending on the specific terms of the warrant agreement.

On February 22, 2011, we issued registered warrants (2011 Warrants) that expired on February 22, 2016 and had a fair value at issuance of $8.0 million.  These warrants contained anti-dilution provisions that in certain circumstances would adjust the exercise price if we issued any common stock, securities convertible into common stock, or other securities (subject to certain exceptions) at a value below the then-existing exercise price of the warrants.  Although by their express terms, these warrants were not subject to potential cash settlement, due to the nature of the anti-dilution provisions, they were classified as derivative liabilities and reported, at each balance sheet date until their expiration, at estimated fair value determined using a trinomial pricing model.  The exercise price of these warrants was adjusted downward to $2.66 per share at the time of the July 2015 public offering.

No warrants were exercised during the three months ended March 31, 2016 and 2015.

Changes in the estimated fair value of warrants classified as derivative liabilities are reported in the accompanying Consolidated Statement of Operations as the “Change in fair value of common stock warrants.”  The change for the quarter ended March 31, 2016 represents the write-off of the derivative liability upon expiration of the underlying warrants in February 2016.

Note 7 – Deerfield Loan

Long-term debt consists solely of amounts due under the Deerfield Loan for the periods presented:

The principal amount of the loan is payable in two $12.5 million annual installments due in each of February 2018 and 2019. Under the Deerfield Loan agreement, the February 2018 installment is subject to potential deferral of one year if we achieve the market capitalization milestone set forth in the Deerfield Loan agreement.  See, Note 9, “Deerfield Loan,” in the Notes to Consolidated Financial Statements in our 2015 Form 10-K.

The following amounts comprise the Deerfield Loan interest expense for the periods presented:

For the three months ended March 31, 2015, cash interest expense represents interest at an annual rate of 8.75% on the outstanding principal amount for the period, paid in cash on a quarterly basis.  For the three months ended March 31, 2016, amortization of prepaid interest expense represents non-cash amortization of the $5 million of Series A and Series B units Deerfield agreed to purchase and accept in our July 2015 public offering in satisfaction of $5 million of future interest payments due under the Deerfield Notes at an interest rate of 8.75%. For the three months ended March 31, 2015, non-cash amortization of debt discount represents the amortization of previously capitalized transaction fees and the amortization of the reduction of the carrying value of the debt due to the fair value of the Deerfield Warrants issued. The amortization of debt costs represents professional fees incurred in connection with the Deerfield Loan.
