1. NATURE OF BUSINESS, ORGANIZATION AND GOING CONCERN

Novelos Therapeutics, Inc. (“Novelos” or the “Company”) is a pharmaceutical company developing compounds for the treatment and diagnosis of cancer. On April 8, 2011, Novelos completed a business combination with Cellectar, Inc. (“Cellectar”), a privately held Wisconsin corporation that designed and developed products to detect, treat and monitor a wide variety of human cancers, and Cell Acquisition Corp. (the “Merger Subsidiary”), a Wisconsin corporation and a wholly owned subsidiary of Novelos. Pursuant to the transaction Cellectar was merged into the Merger Subsidiary (the “Acquisition”, see Note 3). References in these financial statements and notes to “Cellectar” relate to the activities and financial information of Cellectar 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.

Immediately prior to the Acquisition, Novelos completed a 1-for-153 reverse split of its common stock.  Novelos then issued to the shareholders of Cellectar at that date 17,001,596 shares of its common stock as consideration for the Acquisition, representing a ratio of 0.8435 shares of Novelos common stock in exchange for one share of Cellectar common stock (the “Exchange Ratio”) as set forth in the Agreement and Plan of Merger (the “Merger Agreement”) dated April 8, 2011.  The shares issued to Cellectar shareholders in the Acquisition constituted approximately 85% of Novelos’ outstanding common stock after giving effect to the Acquisition.

Accounting principles generally accepted in the United States require that a company whose security holders retain the majority voting interest in the combined business be treated as the acquirer for financial reporting purposes.  Accordingly, the Acquisition was accounted for as a reverse acquisition whereby Cellectar, Inc. was treated as the acquirer for accounting and financial reporting purposes. The financial statements presented herein as of and for the three months ended March 31, 2011 represent the historical financial information of Cellectar, except for the capital structure which represents the historical amounts of Cellectar, retroactively adjusted to reflect the legal capital structure of Novelos by applying the Exchange Ratio. On April, 8, 2011, Cellectar was merged into the Merger Subsidiary a wholly owned subsidiary of Novelos; as such, the financial statements presented herein as of and for the three months ended March 31, 2012 include the consolidated results of the combined company from January 1, 2012 through March 31, 2012.  All per-share amounts and outstanding shares, including all common stock equivalents, and stock options, have been retroactively restated in these financial statements and notes for all periods presented to reflect the capital structure of Novelos by applying the Exchange Ratio. The number of authorized shares of common stock disclosed on the balance sheet (150,000,000) represents the number of authorized shares of Novelos common stock following the Acquisition.

As a result of the Acquisition, the Company has implemented a revised business plan focused on the development of the Cellectar compounds.  Development of Novelos’ other compounds (NOV-002 and NOV-205) has been suspended.  The Company conducts its operations from its headquarters in Madison, Wisconsin and the Company’s executive offices are in Newton, Massachusetts.

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 incurred losses since inception in devoting substantially all of its efforts toward research and development and has an accumulated deficit of $33,837,329 at March 31, 2012. During the three months ended March 31, 2012, the Company generated a net loss of $2,356,903 and the Company expects that it will continue to generate operating losses for the foreseeable future.  The Company believes that its cash on hand is adequate to fund operations into the middle of the third quarter of 2012.  The Company’s ability to execute its operating plan beyond that time 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 balance sheet as of December 31, 2011 has been derived from audited financial statements. The accompanying unaudited consolidated balance sheet as of March 31, 2012, the consolidated statements of operations for the three months ended March 31, 2012 and 2011 and the cumulative period November 7, 2002 (date of inception) through March 31, 2012, and the consolidated statements of cash flows for the three months ended March 31, 2012 and 2011 and the cumulative period November 7, 2002 (date of inception) through March 31, 2012 and the related interim information contained within the notes to the consolidated financial statements have been prepared in accordance with the 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. generally accepted accounting principles for complete financial statements. In the opinion of management, the unaudited interim consolidated financial statements reflect all adjustments, consisting of normal and recurring adjustments, necessary for the fair presentation of the Company’s consolidated financial position at March 31, 2012 and consolidated results of its operations and its cash flows for the three months ended March 31, 2012 and 2011 and the period from November 7, 2002 (inception) to March 31, 2012. The results for the three months ended March 31, 2012 are not necessarily indicative of future results.

These unaudited 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, which was filed with the SEC on March 9, 2012.

Goodwill — Intangible assets at March 31, 2012 consist of goodwill recorded in connection with 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.

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 Topic 505, Equity of the Financial Accounting Standards Board Accounting Standards Codification (“FASB ASC”).  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 and long-term obligations.  The carrying amount of cash equivalents and accounts payable approximate their fair value due to their short-term nature.  The carrying value of 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 are 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 50,419 at March 31, 2012. 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 March 31, 2012 and December 31, 2011, these warrants represented the only outstanding derivative instruments issued or held by the Company. 

New Accounting Pronouncements — In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. Generally Accepted Accounting Principles (“GAAP”) and International Financial Reporting Standards (“IFRSs”).  This standard updates accounting guidance to clarify the measurement of fair value to align the guidance and improve the comparability surrounding fair value measurement within GAAP and IFRSs.  The standard also updates requirements for measuring fair value and expands the required disclosures.  The standard does not require additional fair value measurements and was not intended to establish valuation standards or affect valuation practices outside of financial reporting.  The adoption of this standard on January 1, 2012 did not have a material impact on the Company’s financial statements or required disclosures.

In September 2011, the FASB issued ASU No. 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment.   This standard simplifies how an entity tests goodwill for impairment and allows an entity to first assess qualitative factors in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test.  This standard is effective for entities as of the beginning of a fiscal year that begins after December 15, 2011, interim and annual periods thereafter.  Early adoption is permitted. The Company adopted the provisions of this standard on January 1, 2012. The adoption of this standard did not have a material impact on the Company’s financial statements or required disclosures.
