1. NATURE OF BUSINESS, ORGANIZATION AND GOING CONCERN | |
Cellectar Biosciences, Inc. (the “Company”) is a biopharmaceutical company developing compounds for the treatment and imaging of cancer. Prior to February 11, 2014, the name of the Company was Novelos Therapeutics, Inc. (“Novelos”). On April 8, 2011, Novelos entered into a business combination (the “Acquisition”) with Cellectar, Inc., a privately held Wisconsin corporation that designed and developed products to detect, treat and monitor a wide variety of human cancers. | |
References in these financial statements and notes to “Cellectar, Inc.” relate to the activities and financial information of Cellectar, Inc. prior to the Acquisition, references to “Novelos” relate to the activities and financial information of Novelos prior to the Acquisition and references to “the Company” or “we” or “us” or “our” relate to the activities and obligations of the combined Company following the Acquisition. | |
The Company’s headquarters are located in Madison, Wisconsin. | |
The Company is subject to a number of risks similar to those of other small pharmaceutical companies. Principal among these risks are dependence on key individuals, competition from substitute products and larger companies, the successful development and marketing of its products in a highly regulated environment and the need to obtain additional financing necessary to fund future operations. | |
The accompanying financial statements have been prepared on a basis that assumes that the Company will continue as a going concern and that contemplates the continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has devoted substantially all of its efforts toward research and development and has, during the six months ended June 30, 2014, generated a net loss of approximately $5,029,000. The Company expects that it will continue to generate operating losses for the foreseeable future. See footnote 12 below for further information regarding the Company’s cash resources. The Company’s ability to execute its operating plan depends on its ability to obtain additional funding via the sale of equity and/or debt securities, a strategic transaction or otherwise. The Company plans to continue to actively pursue financing alternatives, but there can be no assurance that it will obtain the necessary funding. The accompanying financial statements do not include any adjustments that might result from the outcome of this uncertainty. | |
The accompanying condensed consolidated balance sheet as of December 31, 2013 has been derived from audited financial statements. The accompanying unaudited condensed consolidated balance sheet as of June 30, 2014, the condensed consolidated statements of operations for the three months and six months ended June 30, 2014 and 2013, the condensed consolidated statements of cash flows for the six months ended June 30, 2014 and 2013 and the related interim information contained within the notes to the condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions, rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all of the information and the notes required by U.S. GAAP for complete financial statements. In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments which are of a nature necessary for the fair presentation of the Company’s consolidated financial position at June 30, 2014 and consolidated results of its operations for the three months and six months ended June 30, 2014, and its cash flows for the six months ended June 30, 2014 and 2013. The results for the six months ended June 30, 2014 are not necessarily indicative of future results. | |
These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes thereto included in the Company’s Form 10-K for the fiscal year ended December 31, 2013, which was filed with the SEC on March 19, 2014. | |
Principles of Consolidation — The consolidated financial statements include the accounts of the Company and the accounts of its wholly-owned subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation. | |
Restricted Cash — The Company accounts for cash that is restricted for other than current operations as restricted cash. Restricted cash at June 30, 2014 and December 31, 2013 consisted of a certificate of deposit of $55,000 required under the Company’s lease agreement for its Madison, Wisconsin facility. | |
Goodwill — At June 30, 2014 and December 31, 2013, the balance of goodwill resulted from the Acquisition. Goodwill is not amortized, but is required to be evaluated for impairment annually or whenever events or changes in circumstances suggest that the carrying value of an asset may not be recoverable. The Company evaluates goodwill for impairment annually in the fourth fiscal quarter and additionally on an interim basis if an event occurs or there is a change in circumstances, such as a decline in the Company’s stock price or a material adverse change in the business climate, which would more likely than not reduce the fair value of the reporting unit below its carrying amount. No such event or change in circumstances occurred; therefore no changes in goodwill were made during the six months ended June 30, 2014. | |
Impairment of Long-Lived Assets — Long-lived assets other than goodwill consist of fixed assets, which we periodically evaluate for potential impairment. Whenever events or circumstances change, an assessment is made as to whether there has been an impairment in the value of long-lived assets by determining whether projected undiscounted cash flows generated by the applicable asset exceed its net book value as of the assessment date. No such event or change in circumstances occurred; therefore, no such impairment occurred during the six months ended June 30, 2014. | |
Stock-Based Compensation — The Company uses the Black-Scholes option-pricing model to calculate the grant-date fair value of stock option awards. The resulting compensation expense, net of expected forfeitures, for awards that are not performance-based is recognized on a straight-line basis over the service period of the award, which is generally three years for stock options. For stock options with performance-based vesting provisions, recognition of compensation expense, net of expected forfeitures, commences if and when the achievement of the performance criteria is deemed probable. The compensation expense, net of expected forfeitures, for performance-based stock options is recognized over the relevant performance period. Non-employee stock-based compensation is accounted for in accordance with the guidance of Financial Accounting Standards Board Accounting Standards Codification (“FASB ASC”) Topic 505, Equity. As such, the Company recognizes expense based on the estimated fair value of options granted to non-employees over their vesting period, which is generally the period during which services are rendered and deemed completed by such non-employees. | |
Fair Value of Financial Instruments — The guidance under FASB ASC Topic 825, Financial Instruments, requires disclosure of the fair value of certain financial instruments. Financial instruments in the accompanying financial statements consist of cash equivalents, accounts payable, convertible debt and long-term obligations. The carrying amount of cash equivalents and accounts payable approximate their fair value due to their short-term nature. The fair value of convertible debt is equal to the fair value of the underlying common stock, which was approximately $2,556,000 at June 30, 2014. The carrying value of remaining long-term obligations, including the current portion, approximates fair value because the fixed interest rate approximates current market interest rates available on similar instruments. | |
Derivative Instruments — The Company generally does not use derivative instruments to hedge exposures to cash flow or market risks. However, certain warrants to purchase common stock that do not meet the requirements for classification as equity, in accordance with the Derivatives and Hedging Topic of the FASB ASC, are classified as liabilities. In such instances, net-cash settlement is assumed for financial reporting purposes, even when the terms of the underlying contracts do not provide for a net-cash settlement. These warrants are considered derivative instruments because the agreements contain “down-round” provisions whereby the number of shares for which the warrants are exercisable and/or the exercise price of the warrants is subject to change in the event of certain issuances of stock at prices below the then-effective exercise price of the warrants. The number of shares issuable under such warrants was 551,365 and 826,365 at June 30, 2014 and December 31, 2013, respectively. The primary underlying risk exposure pertaining to the warrants is the change in fair value of the underlying common stock. Such financial instruments are initially recorded at fair value with subsequent changes in fair value recorded as a component of gain or loss on derivatives on the consolidated statements of operations in each reporting period. If these instruments subsequently meet the requirements for equity classification, the Company reclassifies the fair value to equity. At June 30, 2014 and December 31, 2013, these warrants represented the only outstanding derivative instruments issued or held by the Company. | |
Development Stage Entity — In previous filings, the Company has reported as a “Development Stage Entity”. However, in June 2014, the Financial Accounting Standards Board (FASB) published an Accounting Standards Update 2014-10 (ASU 2014-10) that removed the development stage entity guidance under Accounting Standards Codification Topic 915 (ASC 915) Development Stage Entities, thereby removing the financial reporting distinction between development stage entities and other reporting entities. | |
In addition, ASU 2014-10 eliminates the requirements for development stage entities to (1) present inception-to-date information in the statements of income, cash flows, and shareholder equity, (2) label the financial statements as those of a development stage entity, (3) disclose a description of the development stage activities in which the entity is engaged, and (4) disclose in the first year in which the entity is no longer a development stage entity that in prior years it had been in the development stage. | |
Presentation and disclosure requirements under ASC 915 are no longer required for the first annual period beginning after December 15, 2014, including interim periods therein. Earlier adoption of the new guidance for ASC 915 is permitted for any annual or interim period for which financial statements have not yet been issued for public business entities. Accordingly, the Company has elected to adopt these changes effective with the filing of this Form 10-Q. | |

2. FAIR VALUE | ||||||||||||||
In accordance with the Fair Value Measurements and Disclosures Topic of the FASB ASC 820, the Company groups its financial assets and financial liabilities generally measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. | ||||||||||||||
· | Level 1: Input prices quoted in an active market for identical financial assets or liabilities. | |||||||||||||
· | Level 2: Inputs other than prices quoted in Level 1, such as prices quoted for similar financial assets and liabilities in active markets, prices for identical assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data. | |||||||||||||
· | Level 3: Input prices quoted that are significant to the fair value of the financial assets or liabilities which are not observable or supported by an active market. | |||||||||||||
To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. 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. | ||||||||||||||
The Company had issued warrants to purchase 1,365 shares of common stock prior to the Acquisition (“Legacy Warrants”) that are classified within the Level 2 hierarchy. Additionally, the Company issued warrants to purchase an aggregate of 825,000 common shares in a February 2013 public offering (“February 2013 Public Offering Warrants”). On February 20, 2014, warrants to purchase 275,000 shares of common stock issued in the February 2013 offering expired. The remaining 550,000 warrants are classified within the Level 3 hierarchy. | ||||||||||||||

In order to estimate the fair value of the Legacy Warrants considered to be derivative instruments, the Company uses the Black-Scholes option pricing model and assumptions that consider, among other variables, the fair value of the underlying stock, risk-free interest rate, volatility, expected life and dividend rates. Assumptions used are generally consistent with those disclosed for stock-based compensation (see Note 6). | ||||||||||||||
In order to estimate the value of the February 2013 Public Offering Warrants considered to be derivative instruments as of June 30, 2014, the Company uses a modified option-pricing model together with assumptions that consider, among other variables, the fair value of the underlying stock, risk-free interest rate of 1.76% (compared with risk-free interest rate of 0.92% as of December 31, 2013), volatility of 108% (compared with 109% as of December 31, 2013), contractual term of 6 years (also 6 years as of December 31, 2013), future financing requirements and dividend rates. | ||||||||||||||
The assumptions used to estimate the value of the February 2013 Public Offering Warrants as of December 31, 2013 include the fair value of the underlying stock, risk free interest rates ranging from 0.07% to 1.27%, volatility ranging from 75% to 115%, the contractual term of the warrants ranging from 0.14 to 4.14 years, future financing requirements and dividend rates. The future financing estimates are based on the Company’s estimates of anticipated cash requirements over the term of the warrants as well as the frequency of required financings based on its assessment of its historical financing trends and anticipated future events. Due to the nature of these inputs and the valuation technique utilized, these warrants are classified within the Level 3 hierarchy. | ||||||||||||||

Convertible Debt [Abstract] | ' |
Debt Disclosure [Text Block] | ' |
3. CONVERTIBLE DEBT | |
On February 5, 2014, the Company entered into a securities purchase agreement with certain accredited investors to sell $4,000,000 in principal amount of convertible debentures and warrants to purchase 400,000 shares of its common stock for an aggregate purchase price of $4,000,000. On February 6, 2014, the Company completed the sale of the debentures and warrants (the “February 2014 Private Placement”). | |
Debentures | |
The debentures mature on February 6, 2016 and are convertible at any time at a conversion price of $10.00 per share into an aggregate of 400,000 shares of common stock. The debentures accrue interest at an annual rate of 8%, payable upon redemption or conversion, in cash or shares of the Company’s common stock. During the six months ended June 30, 2014, the Company accrued $128,000 in interest expense, which is included in accrued liabilities as of June 30, 2014. The debenture conversion price and the common stock issuable pursuant to the debentures are subject to adjustment for stock dividends, stock splits or similar capital reorganizations so that the rights of the debenture holders after such event will be equivalent to the rights of debenture holders prior to such event. | |
The Company may elect to redeem the debentures prior to the maturity date upon 30-day notice to the holder. In the event of any sale of securities by the Company resulting in aggregate gross proceeds of at least $2,000,000 (a “Subsequent Financing”), the holder shall have the right to require the Company to redeem some or all of the then outstanding principal amount of the debenture, plus all accrued but unpaid interest and other amounts due in respect of the debenture, in an amount equal to the amount of the holder’s investment in the Subsequent Financing, by delivering notice to the Company on or before the consummation date of the Subsequent Financing. If, within 21 months after the issuance of the debentures, the Company raises gross proceeds of at least $8,000,000, in the aggregate, in one or more subsequent financings (the “Minimum Proceeds”), the Company may, by notice given within three trading days after the receipt of the Minimum Proceeds, compel holders to convert all or part of the then outstanding principal amount of the debentures and accrued but unpaid interest and other amounts. | |
Other than as specifically permitted under in the debentures, as long as any of the debentures remain outstanding, the Company may not, without the consent of holders of a majority in principal amount of the then outstanding debentures: incur any indebtedness for borrowed money; grant any liens on its property or assets; repurchase shares of its common stock or common stock equivalents; repurchase or otherwise acquire any indebtedness; pay cash dividends or distributions on any equity securities; enter into any transaction with any affiliate of the Company which would be required to be disclosed in any public filing with the SEC, unless such transaction is made on an arm’s-length basis and expressly approved by a majority of the disinterested directors of the Company; or enter into any agreement with respect to any of the foregoing. See footnote 12 for discussion of the security interest extended to these debentures as consideration for the consent of the holders to the issuance of the promissory notes in July 2014. | |
If any event of default occurs, the outstanding principal amount of the debentures, plus accrued but unpaid interest and other amounts owing in respect thereof through the date of acceleration, shall become, at the holder’s election, immediately due and payable in cash. If such amounts are not paid within 5 days after the occurrence of any event of default, interest shall begin to accrue at the lesser of 12% per annum or the maximum rate permitted under applicable law. Events of default consist of: any default in the payment of amounts due and payable that is not cured within three trading days; failure of the Company to observe or perform any other covenant or agreement contained in the Debentures that is not cured within the earlier to occur of five trading days after notice of such failure sent by any holder of debentures or ten trading days after the Company has become aware of such failure; the occurrence of any uncured material default or event of default under the other transaction documents or any other material agreement, lease, document or instrument under which the Company or any of its subsidiaries is obligated; any representations or warranties made in the debentures or other transaction documents being materially false when made; an institution of any voluntary or involuntary bankruptcy or other insolvency proceeding or similar or related events; default on any borrowings in excess of $150,000; the Company’s common stock being ineligible for quotation on a trading market for greater than five trading days; the Company entering into any change in control transaction; the Company’s failure to deliver shares of common stock as required upon conversion of the debentures; or the Company being the subject of a monetary judgment greater than $100,000. | |
Common Stock Purchase Warrants | |
The warrants have an exercise price of $20.00 and, if unexercised, expire on February 6, 2019. The warrants are exercisable only following the full or partial conversion of the associated debentures, and in the event of a partial conversion the warrant shall become exercisable only for a proportionate number of the total shares subject to the warrant. In the event any debentures cease to be outstanding prior to the associated warrants becoming exercisable, whether by reason of repayment, prepayment, redemption or otherwise, the associated warrants will automatically terminate. | |
The warrant exercise price and the number of shares of common stock issuable pursuant to the warrants are subject to adjustment for stock dividends, stock splits or similar capital reorganizations so that the rights of the warrant holders after such event will be equivalent to the rights of warrant holders prior to such event. | |
The Company determined that the warrants associated with the convertible debentures meet the requirements for classification as equity. Therefore, the relative fair value of the warrants at the date of issuance of $254,000 has been included as a component of stockholders’ equity. In order to estimate the value of the these warrants the Company used a probability weighted valuation model together with assumptions that considered, among other variables, the fair value of the underlying stock, a risk-free interest rate of 1.52%, a volatility of 110%, a 0% dividend rate, a contractual term of 5 years, and an estimate of the probability that the warrants will become exercisable upon conversion of the associated debt. | |
Following the allocation of the relative fair value of the warrants to equity, the remaining value of approximately $3,746,000, at the date of issuance, was allocated to the convertible debentures. The resulting discount on the debentures of $254,000 will be accreted to interest expense over the shorter of the time to maturity or conversion. During the six months ended June 30, 2014, the Company recorded approximately $51,000 of non-cash expense related to accretion of the discount on the debentures. | |

4. REVERSE STOCK SPLIT AND RECAPITALIZATION | |
At the annual meeting of stockholders held on May 22, 2014, the Company’s stockholders approved an amendment to the certificate of incorporation to effect a reverse split of the Company’s common stock at a ratio between 1:10 to 1:20 in order to satisfy requirements for the listing of the Company’s common stock on the NASDAQ Capital Market. In addition, the proposal approved by the stockholders provided that if the reverse split was effected, the number of shares of common stock that the Company is authorized to issue would be reduced from 150,000,000 to the greater of (A) 20,000,000 and (B) the number of shares equal to three (3) times the sum of the number of all shares of common stock outstanding and the number of shares of common stock issuable upon exercise or conversion of all outstanding options, warrants and convertible debt. The Company’s stockholders further authorized the board of directors to determine the ratio at which the reverse split would be effected and the corresponding reduction in authorized shares of common stock by filing an appropriate amendment to the Company’s certificate of incorporation. The board of directors authorized the ratio of the reverse split and corresponding reduction in authorized shares on June 6, 2014 and effective at the close of business on June 13, 2014, the second amended and restated certificate of incorporation was amended to effect a 1-for-20 reverse split of the Company’s common stock (the “Listing Reverse Split”) and reduce the number of authorized shares of common stock to 20,000,000 from 150,000,000. All share and per share numbers included in this Form 10-Q give effect to the Listing Reverse Split. | |

In October 2013, the Company granted options to purchase 264,278 shares of common stock in connection with the appointment of its then Acting Chief Executive Officer, including options to purchase 96,278 shares of common stock at $15.00 per share (the “Anti-dilution Option”), exercisable as shares of the Company’s common stock are issued following the exercise of outstanding warrants to purchase up to 96,278 shares of the Company’s common stock, in the ratio of one option share for each 19 shares issued upon warrant exercise. No compensation expense was recognized related to these options as the Company was not able to conclude that the achievement of the performance condition was probable. On February 20, 2014, warrants to purchase 275,000 shares of common stock at an exercise price of $10.00 per share expired unexercised and as a result, the number of shares subject to the Anti-dilution Option was reduced by 14,474 shares, according to its terms. | ||||||||||||||
Assumptions Used In Determining Fair Value | ||||||||||||||
Valuation and amortization method. The fair value of each stock award is estimated on the grant date using the Black-Scholes option-pricing model. The estimated fair value of employee stock options is amortized to expense using the straight-line method over the vesting period. The estimated fair value of the non-employee options is amortized to expense over the period during which a non-employee is required to provide services for the award (usually the vesting period). | ||||||||||||||
Volatility. The Company estimates volatility based on an average of (1) the Company’s historical volatility since its common stock has been publicly traded and (2) review of volatility estimates of publicly held drug development companies with similar market capitalizations. | ||||||||||||||
Risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected term assumption. | ||||||||||||||
Expected term. The expected term of stock options granted is based on an estimate of when options will be exercised in the future. The Company applied the simplified method of estimating the expected term of the options, as described in the SEC’s Staff Accounting Bulletins 107 and 110, as the historical experience is not indicative of the expected behavior in the future. The expected term, calculated under the simplified method, is applied to groups of stock options that have similar contractual terms. Using this method, the expected term is determined using the average of the vesting period and the contractual life of the stock options granted. The Company applied the simplified method to non-employees who have a truncation of term based on termination of service and utilizes the contractual life of the stock options granted for those non-employee grants which do not have a truncation of service. | ||||||||||||||
Forfeitures. The Company records stock-based compensation expense only for those awards that are expected to vest. A forfeiture rate is estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. An annual forfeiture rate of 2% and 0% was applied to all unvested options for employees and directors, respectively for the six months ended June 30, 2014 and for the year ended December 31, 2013. Ultimately, the actual expense recognized over the vesting period will be for only those shares that vest. | ||||||||||||||
The following table summarizes weighted-average values and assumptions used for options granted to employees, directors and consultants in the periods indicated: | ||||||||||||||

The aggregate intrinsic value of options outstanding is calculated based on the positive difference between the estimated per-share fair value of common stock at the end of the respective period and the exercise price of the underlying options. There have been no option exercises to date. Shares of common stock issued upon the exercise of options are from authorized but unissued shares. | ||||||||||||||
As of June 30, 2014, there was approximately $1,869,000 of total unrecognized compensation cost related to unvested stock-based compensation arrangements. Of this total amount, the Company expects to recognize approximately $1,096,000, $570,000, and $203,000 during 2014, 2015, and 2016, respectively. The Company expects 273,106 unvested options to vest in the future. In addition, there are outstanding options to purchase 81,805 shares of common stock that vest upon the occurrence of future events. The Company was not able to conclude that the achievement of the performance condition is probable; therefore, the Company has not recognized any expense associated with the $418,000 fair value of these awards. Recognition of expense will begin when and if the Company determines that achievement of the performance condition is probable. The weighted-average grant-date fair value of vested and unvested options outstanding at June 30, 2014 was $16.66 and $5.98, respectively. | ||||||||||||||

7. INCOME TAXES | |
The Company accounts for income taxes in accordance with the liability method of accounting. Deferred tax assets or liabilities are computed based on the difference between the financial statement and income tax basis of assets and liabilities, and net operating loss carryforwards, (NOLs) using the enacted tax rates. Deferred income tax expense or benefit is based on changes in the asset or liability from period to period. The Company did not record a provision or benefit for federal, state or foreign income taxes for the six months ended June 30, 2014 or 2013 because the Company has experienced losses on a tax basis since inception. Because of the limited operating history, continuing losses and uncertainty associated with the utilization of the NOLs in the future, management has provided a full allowance against the value of its gross deferred tax asset. | |
The Company also accounts for the uncertainty in income taxes related to the recognition and measurement of a tax position taken or expected to be taken in an income tax return. The Company follows the applicable accounting guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition related to the uncertainty in income tax positions. No uncertain tax positions have been identified. | |

8. NET LOSS PER SHARE | ||||||
Basic net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing net loss, as adjusted, by the sum of the weighted average number of shares of common stock and the dilutive potential common stock equivalents then outstanding. Potential common stock equivalents consist of stock options and warrants and convertible debt. Since there is a net loss attributable to common stockholders for the six months ended June 30, 2014 and 2013, the inclusion of common stock equivalents in the computation for those periods would be antidilutive. Accordingly, basic and diluted net loss per share is the same for all periods presented. | ||||||
The following potentially dilutive securities have been excluded from the computation of diluted net loss per share since their inclusion would be antidilutive: | ||||||

Litigation | |
The Company is party to the following legal matter. | |
BAM Dispute | |
From its inception through 2010, Novelos was primarily engaged in the development of certain oxidized glutathione-based compounds for application as therapies for disease, particularly cancer. These compounds were originally developed in Russia and in June 2000, Novelos acquired commercial rights from the Russian company (“ZAO BAM”) which owned the compounds and related Russian patents. In April 2005, Novelos acquired worldwide rights to the compounds (except for the Russian Federation) in connection with undertaking extensive development activities in an attempt to secure US Food and Drug Administration (“FDA”) approval of the compounds as therapies. These development activities culminated in early 2010 in an unsuccessful Phase 3 clinical trial of an oxidized glutathione compound (NOV-002) as a therapy for non-small cell lung cancer. After the disclosure of the negative outcome of the Phase 3 clinical trial in 2010, ZAO BAM claimed that Novelos modified the chemical composition of NOV-002 without prior notice to or approval from ZAO BAM, constituting a material breach of the June 2000 technology and assignment agreement. In September 2010, Novelos filed a complaint in Massachusetts Superior Court seeking a declaratory judgment by the court that the June 2000 agreement has been entirely superseded by the April 2005 agreement and that the obligations of the June 2000 agreement have been performed and fully satisfied. ZAO BAM answered the complaint and alleged counterclaims. In August 2011, Novelos filed a motion for judgment on the pleadings as to the declaratory judgment count and all counts of ZAO BAM’s amended counterclaims. On October 17, 2011, the court ruled in favor of Novelos on each of the declaratory judgment claims and dismissed all counts of ZAO BAM’s counterclaim. Judgment in our favor was entered on October 20, 2011. On November 14, 2011 ZAO BAM filed a notice of appeal. On November 1, 2013, ZAO BAM’s appeal was docketed with the Massachusetts Appeals Court. BAM’s appellate brief and the Company’s opposition have been filed with the Appeals Court but oral arguments have not yet been scheduled. On April 14, 2014, BAM filed a motion to modify the record on appeal. The Company has opposed the motion. | |

10. RESTRUCTURING COSTS | |
During 2013 the Company had several changes to its board composition and executive management, including the relocation of the Company’s principal executive offices from Newton, Massachusetts to its corporate headquarters in Madison, Wisconsin. During the six months ended June 30, 2014, the Company incurred approximately $222,000 of costs associated with the closure of the executive offices in Newton, Massachusetts and accruals related to severance agreements. This amount has been classified as restructuring costs on the accompanying statement of operations. | |
In connection with the Acquisition, the responsibilities of the Company’s Vice President of Finance, Chief Financial Officer and Treasurer (CFO) and those of the Director of Financial Reporting were transitioned to the Company’s headquarters in Madison, Wisconsin. As a result, the Company’s relationship with both employees terminated in June 2014. These two employees received lump-sum severance payments totaling approximately $160,000, which is included in the approximately $222,000 restructuring costs presented in the accompanying Condensed Consolidated Statement of Operations. Benefits will continue for these employees for six and four months, respectively, following termination. | |
In addition, all unvested options held by the former CFO were credited with an additional six months vesting and the vested options held by this employee shall be exercisable for eighteen months following termination. All unvested options held by the former Director of Financial Reporting shall be exercisable for twelve months following termination. | |
The Company does not anticipate any further costs related to the relocation and restructuring. | |

The Company and a group of lenders entered into a Note Purchase and Security Agreement dated as of July 29, 2014 providing for borrowing by the Company of up to an aggregate of $1,000,000 upon the issuance of the Company’s secured promissory notes (the “Notes”) bearing interest of 8% per annum and having a stated maturity of 60 days from issuance or the earlier closing of an equity financing with gross proceeds to the Company of $1,000,000. The Notes are secured by a lien on substantially all assets of the Company, now existing or subsequently acquired. The Company borrowed an aggregate of $617,500 at an initial closing on July 29, 2014. Any borrowing of the remaining $382,500 balance of the $1,000,000 is at the option of the lenders. In connection with the entry into the Note Purchase and Security Agreement, the Company obtained the consent of the holders of its outstanding convertible debentures in exchange for the extension of the security interest on all such assets of the Company to the convertible debentures, pari passu with the Notes. | |

Consolidation, Policy [Policy Text Block] | ' |
Principles of Consolidation — The consolidated financial statements include the accounts of the Company and the accounts of its wholly-owned subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation. | |
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block] | ' |
Restricted Cash — The Company accounts for cash that is restricted for other than current operations as restricted cash. Restricted cash at June 30, 2014 and December 31, 2013 consisted of a certificate of deposit of $55,000 required under the Company’s lease agreement for its Madison, Wisconsin facility. | |
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block] | ' |
Goodwill — At June 30, 2014 and December 31, 2013, the balance of goodwill resulted from the Acquisition. Goodwill is not amortized, but is required to be evaluated for impairment annually or whenever events or changes in circumstances suggest that the carrying value of an asset may not be recoverable. The Company evaluates goodwill for impairment annually in the fourth fiscal quarter and additionally on an interim basis if an event occurs or there is a change in circumstances, such as a decline in the Company’s stock price or a material adverse change in the business climate, which would more likely than not reduce the fair value of the reporting unit below its carrying amount. No such event or change in circumstances occurred; therefore no changes in goodwill were made during the six months ended June 30, 2014. | |
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | ' |
Impairment of Long-Lived Assets — Long-lived assets other than goodwill consist of fixed assets, which we periodically evaluate for potential impairment. Whenever events or circumstances change, an assessment is made as to whether there has been an impairment in the value of long-lived assets by determining whether projected undiscounted cash flows generated by the applicable asset exceed its net book value as of the assessment date. No such event or change in circumstances occurred; therefore, no such impairment occurred during the six months ended June 30, 2014. | |
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | ' |
Stock-Based Compensation — The Company uses the Black-Scholes option-pricing model to calculate the grant-date fair value of stock option awards. The resulting compensation expense, net of expected forfeitures, for awards that are not performance-based is recognized on a straight-line basis over the service period of the award, which is generally three years for stock options. For stock options with performance-based vesting provisions, recognition of compensation expense, net of expected forfeitures, commences if and when the achievement of the performance criteria is deemed probable. The compensation expense, net of expected forfeitures, for performance-based stock options is recognized over the relevant performance period. Non-employee stock-based compensation is accounted for in accordance with the guidance of Financial Accounting Standards Board Accounting Standards Codification (“FASB ASC”) Topic 505, Equity. As such, the Company recognizes expense based on the estimated fair value of options granted to non-employees over their vesting period, which is generally the period during which services are rendered and deemed completed by such non-employees. | |
Fair Value of Financial Instruments, Policy [Policy Text Block] | ' |
Fair Value of Financial Instruments — The guidance under FASB ASC Topic 825, Financial Instruments, requires disclosure of the fair value of certain financial instruments. Financial instruments in the accompanying financial statements consist of cash equivalents, accounts payable, convertible debt and long-term obligations. The carrying amount of cash equivalents and accounts payable approximate their fair value due to their short-term nature. The fair value of convertible debt is equal to the fair value of the underlying common stock, which was approximately $2,556,000 at June 30, 2014. The carrying value of remaining long-term obligations, including the current portion, approximates fair value because the fixed interest rate approximates current market interest rates available on similar instruments. | |
Derivatives, Policy [Policy Text Block] | ' |
Derivative Instruments — The Company generally does not use derivative instruments to hedge exposures to cash flow or market risks. However, certain warrants to purchase common stock that do not meet the requirements for classification as equity, in accordance with the Derivatives and Hedging Topic of the FASB ASC, are classified as liabilities. In such instances, net-cash settlement is assumed for financial reporting purposes, even when the terms of the underlying contracts do not provide for a net-cash settlement. These warrants are considered derivative instruments because the agreements contain “down-round” provisions whereby the number of shares for which the warrants are exercisable and/or the exercise price of the warrants is subject to change in the event of certain issuances of stock at prices below the then-effective exercise price of the warrants. The number of shares issuable under such warrants was 551,365 and 826,365 at June 30, 2014 and December 31, 2013, respectively. The primary underlying risk exposure pertaining to the warrants is the change in fair value of the underlying common stock. Such financial instruments are initially recorded at fair value with subsequent changes in fair value recorded as a component of gain or loss on derivatives on the consolidated statements of operations in each reporting period. If these instruments subsequently meet the requirements for equity classification, the Company reclassifies the fair value to equity. At June 30, 2014 and December 31, 2013, these warrants represented the only outstanding derivative instruments issued or held by the Company. | |
Development Stage Entity, Policy [Policy Text Block] | ' |
Development Stage Entity — In previous filings, the Company has reported as a “Development Stage Entity”. However, in June 2014, the Financial Accounting Standards Board (FASB) published an Accounting Standards Update 2014-10 (ASU 2014-10) that removed the development stage entity guidance under Accounting Standards Codification Topic 915 (ASC 915) Development Stage Entities, thereby removing the financial reporting distinction between development stage entities and other reporting entities. | |
In addition, ASU 2014-10 eliminates the requirements for development stage entities to (1) present inception-to-date information in the statements of income, cash flows, and shareholder equity, (2) label the financial statements as those of a development stage entity, (3) disclose a description of the development stage activities in which the entity is engaged, and (4) disclose in the first year in which the entity is no longer a development stage entity that in prior years it had been in the development stage. | |
Presentation and disclosure requirements under ASC 915 are no longer required for the first annual period beginning after December 15, 2014, including interim periods therein. Earlier adoption of the new guidance for ASC 915 is permitted for any annual or interim period for which financial statements have not yet been issued for public business entities. Accordingly, the Company has elected to adopt these changes effective with the filing of this Form 10-Q. | |
