(1) Description of Business

Enzon Pharmaceuticals, Inc. (together with its subsidiaries, “Enzon” or the “Company”) receives royalty revenues from existing licensing arrangements with other companies primarily related to sales of six marketed products, namely, PegIntron ^® , Sylatron ^® , Macugen ^® , CIMZIA ^® , Oncaspar and Adagen. The Company currently has no clinical operations and limited corporate operations. The Company operates in one business segment. The Company’s Principal Executive Officer (chief operating decision maker) reviews the Company’s operating results on an aggregate basis and manages the Company’s operations as a single operating unit. The Company’s operations and assets reside exclusively in the United States.

The Company was previously dedicated to the research and development of innovative therapeutics for patients with high unmet medical needs. In December 2012, the Company announced that its Board of Directors retained Lazard Frères & Co. LLC to act as financial advisor in a review of the possible sale or disposition of one or more corporate assets or a sale of the Company and that the Board of Directors established a special committee to oversee the sale review process. In connection with the sale review process, the Company substantially suspended all clinical development activities with a goal of conserving capital and maximizing value returned to the Company’s stockholders. In April 2013, the Company announced that it had concluded a thorough review of the possible sale or disposition of one or more corporate assets, or a sale of the Company. The review did not result in a definitive offer to acquire the Company or all or substantially all of the Company’s assets. In the same announcement, the Company also announced that its Board of Directors intends to distribute excess cash, expected to arise from ongoing royalty revenues, in the form of periodic dividends to stockholders.

On April 30, 2013, pursuant to the terms of an asset purchase agreement entered into on the same date (the “Belrose APA”), the Company completed the sale of all of its right, title and interest in its Customized PEGylation Linker Technology platform and related assets to Belrose Pharma Inc. (“Belrose”) for aggregate consideration of $ 700,000 . The assets sold included (i) intellectual property and know-how associated with the PEGylation platform (including certain patents), (ii) patents and know-how related to PEG-SN38, (iii) patents and know-how associated with certain of the Company’s internal clinical programs and (iv) certain related supplies and equipment. In addition, the Company assigned to Belrose the Company’s existing license agreement with Zhejiang Hisun Pharmaceutical Co., Ltd. The Belrose APA had also provided for the sale by the Company of its interest in the Locked Nucleic Acid (LNA) Technology platform and related assets for $ 100,000 at a second closing; however, the conditions to the second closing were not satisfied. The Belrose APA also entitles the Company to receive from Belrose additional potential payments, including a share of net revenues that may be received from Hisun related to PEG-SN38 rights in China as well as a share of other potential partnering revenues. The achievement of any of these potential payments is uncertain. The assets sold to Belrose did not include any of the Company’s existing rights to receive royalties on PegIntron®, Sylatron®, Macugen®, CIMZIA®, OMONTYS®, Oncaspar or Adagen.

On October 21, 2013, the Company terminated its License and Collaboration Agreement with Santaris Pharma A/S (“Santaris”) whereby the Company will return to Santaris the rights to molecules utilizing LNA technology including the mRNA antagonists targeting Hypoxia-Inducible Factor-1 alpha (HIF-1 alpha), the Androgen Receptor (AR), HER3, and Beta-catenin. See Note 15, “Subsequent Event” for further details.

The Company has no intention of resuming any clinical development activities.

(2) Basis of Presentation

Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements have been prepared from the books and records of the Company in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and Rule 10-01 of Regulation S-X promulgated by the U.S. Securities and Exchange Commission. Accordingly, these financial statements do not include all of the information and footnotes required for complete annual financial statements. Interim results are not necessarily indicative of the results that may be expected for the full year. Interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

	5

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated as part of the consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates include the carrying value of property and equipment, valuation of investments, legal and contractual contingencies, research and development expenses, stock-based compensation, and income taxes. Although management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, actual results could differ from these estimates.

(3) New Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (ASU 2013-02). ASU 2013-02 requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety to net income. The amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. An entity is required to provide this information together, in one location, either on the face of the statement where net income is presented or as a separate disclosure in the notes to the financial statements. The amendments are effective prospectively for reporting periods beginning after December 15, 2012. The adoption of ASU 2013-02 did not have a material impact on the Company’s financial position or results of operations.

The FASB recently issued ASU “Presentation of Financial Statements (Topic 205) Liquidation Basis of Accounting” (ASU 2013-07) that requires an entity to prepare its financial statements using the liquidation basis of accounting when liquidation is imminent, as defined in ASU 2013-7. ASU 2013-7’s objective is to eliminate diverse practices by providing guidance about when and how to apply the model. The guidance applies to all entities except for investment companies regulated under the Investment Company Act of 1940.

ASU 2013-7 is effective for both public and nonpublic entities that determine liquidation is imminent during annual reporting periods beginning after December 15, 2013, and interim reporting periods within those annual periods. An entity preparing its financial statements on a going-concern basis at the effective date that is required to use the liquidation basis of accounting is required to account for any differences between its existing measurements and the measurements under ASU 2013-7 through a cumulative-effect adjustment. Early adoption is permitted. The Company has evaluated the impact of ASU 2013-7 on the Company’s consolidated financial statements, and has determined that it does not currently have an impact on Company’s financial statements.

In July 2013, the FASB issued ASU 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” This update amends ASC 740, “Income Taxes,” to require that in certain cases, an unrecognized tax benefit, or portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward when such items exist in the same taxing jurisdiction. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date, and retrospective application is permitted. The Company is currently evaluating the impact this update will have on its financial statements.

(4) Financial Instruments and Fair Value

The carrying values of cash, cash equivalents, marketable securities, other current assets, accounts payable, accrued expenses and other current liabilities in the Company’s condensed consolidated balance sheets approximated their fair values at September 30, 2013 and December 31, 2012 due to their short-term nature.

	6

(5) Marketable Securities

The Company held no marketable securities at September 30, 2013 . The amortized cost, gross unrealized holding gains or losses, and fair value of the Company’s marketable securities by major security type at December 31, 2012 were as follows (in thousands):

	Amortized Cost		Gross Unrealized Holding Gains		Gross Unrealized Holding Losses		Fair Value*

Corporate bonds	$	86,769	$	82	$	(11)	$	86,840
Commercial paper		30,482		8		-		30,490
U.S. government-sponsored agency		2,057		4		-		2,061
	$	119,308	$	94	$	(11)	$	119,391

* Included in current marketable securities at December 31, 2012.

All marketable securities at December 31, 2012 were classified as available-for-sale.

For the three months ended September 30, 2013, the Company did not realize any gains from the sale of marketable securities. For the nine months ended September 30, 2013, the Company realized gains from the sale of marketable securities of $ 0.3 million. For the three months ended September 30, 2012, the Company realized net gains from the sale of marketable securities of $ 1.0 million. For the nine months ended September 30, 2012, the Company realized net gains from the sale of marketable securities of $ 1.0 million. The Company includes realized gain and losses, if any, in the accompanying Condensed Consolidated Statements of Comprehensive Income, in Interest and Other Income.

Impairment assessments are made at the individual security level each reporting period. When the fair value of an investment is less than its cost at the balance sheet date, a determination is made as to whether the impairment is other-than-temporary and, if it is other-than-temporary, an impairment loss is recognized in earnings equal to the difference between the investment’s amortized cost and fair value at such date. As of December 31, 2012, marketable securities with fair value of $ 38.1 million were in an unrealized loss position. However, none of the underlying investments has been in a continuous loss position longer than twelve months, and no other-than-temporary impairment is deemed to have occurred.

As of December 31, 2012, the Company’s marketable securities are all valued based on Level 2 inputs. Fair value is determined from available Level 2 vendor quoted prices utilizing observable inputs based on active markets. The Company utilizes a financial institution to provide pricing for securities in the Company’s portfolio, and reviews documentation from the sources that detailed the pricing techniques and methodologies used by these sources and determines if their policies adequately considered market activity, either based on specific transactions for the particular security type or based on modeling of securities with similar credit quality, duration, yield and structure that were recently transacted. The Company continues to monitor any changes or modifications to their process by reviewing their documentation on internal controls for pricing and market reviews.

(6) Property and Equipment and Assets Held for Sale

In connection with the sublease of a portion of its headquarters as discussed in Note 14, the Company plans to sell a portion of its property and equipment to Axcellerate and to sell its remaining property and equipment through a third party liquidator. As such, the Company has classified its property and equipment as Assets Held for Sale as of September 30, 2013. The Company reduced the carrying value of its property and equipment to estimated fair market value based on third-party independent appraisals as of December 31, 2012.

	7

(7) Notes Payable

The Company’s 4 % convertible notes matured on June 1, 2013, and the Company repaid in full at maturity the outstanding principal amount of $ 115.8 million, together with accrued interest thereon. As of December 31, 2012, the principal amount of the convertible notes outstanding was $ 115.8 million.

During 2012, the Company retired $ 13.6 million in principal amount of its then outstanding 4 % convertible notes at a price above par and wrote-off approximately $ 62,000 of deferred debt issuance costs. As of December 31, 2012, the balance of unamortized deferred debt issuance costs was approximately $ 0.2 million.

Accrued interest (included in accrued expenses) on the Company’s 4 % convertible notes amounted to $ 0.4 million as of December 31, 2012.

(8) Stockholders’ Equity

On December 21, 2010, the Company announced that its Board of Directors had authorized a share repurchase program, under which the Company is authorized to repurchase up to $ 200.0 million of the Company’s outstanding common stock. The Company has suspended repurchases under the share repurchase program. No shares were purchased during the first nine months of 2013. During the second quarter of 2012, the Company repurchased and retired 788,300 shares at a cost of $ 5.3 million under this program.

(9) Supplemental Cash Flow Information

The Company considers all highly liquid investment securities with maturities when purchased of three months or less to be cash equivalents. During the nine months ended September 30, 2013 and 2012, there were interest payments of $ 2.3 million and $ 4.8 million, respectively, related to the Company’s notes payable. Income tax payments of $ 158,000 and $ 33,000 were made during the nine months ended September 30, 2013 and 2012, respectively.

(10) Earnings Per Common Share

Basic earnings per common share is computed by dividing the income available to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Restricted stock units (nonvested shares) are not considered to be outstanding shares until the vesting criteria (service and/or performance) have been satisfied.

For purposes of calculating diluted earnings per common share, the denominator includes both the weighted-average number of shares of common stock outstanding and the number of common stock equivalents if the inclusion of such common stock equivalents is dilutive. Dilutive common stock equivalents potentially include stock options and nonvested shares using the treasury stock method and the number of shares issuable upon conversion of the Company’s convertible notes payable for the period that they were outstanding. As of September 30, 2013, shares issuable under the employee stock purchase plan (ESPP) no longer have a dilutive effect due to the plan termination. Earnings per common share information as follows (in thousands, except per share amounts):

In December 2012, the Company announced a plan to reduce its workforce by approximately 15 - 20 employees. In March 2013, in an effort to continue to cut ongoing operating expenses, the Company committed to a plan to reduce its workforce from 19 employees to 12 employees. The Company continued to reduce its workforce during the second quarter of 2013 from 12 to 5 employees. The Company had 4 employees at the end of the third quarter of 2013.

The Company also reversed previously recognized expense of $ 132,000 due to changes in estimates of employee separation costs.

During the third quarter of 2013, the Company incurred restructuring charges of $ 794,000 , primarily related to the sublease of 30,000 square feet of space in its headquarters, representing the present value of future lease obligations in excess of future sublease income. The Company has classified $ 503,000 of the charge as current and $ 291,000 as non-current.

The Company has also incurred costs from restructuring activities undertaken during 2011 as part of the transition from a fully integrated biopharmaceutical company with research, manufacturing, and marketing operations to a biotechnology company focused primarily on research and development. During the second half of 2011, the Company incurred additional restructuring costs as part of a plan to more closely align its resources and capital with on-going research and development activities.

Restructuring costs are charged to earnings and accrued as a liability at the time they are considered probable and reasonably estimable. Restructuring costs include employee separation benefits and lease termination costs for facilities that have been vacated and are included in accrued expenses on the accompanying Condensed Consolidated Balance Sheets.

The following table summarizes the changes in the Company’s accrued restructuring liabilities during the first three quarters of 2013 (in thousands) based on the quarter in which the related restructuring measures were initiated:

The Company expects to record a charge related to this agreement during the fourth quarter of 2013.

The Company has been involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material effect on the Company’s consolidated financial position, results of operations, or liquidity.

The Company had a non-cancelable lease obligation for certain office and production facilities that had been vacated and sublet. During 2013, the Company terminated the lease of the Bridgewater, New Jersey facility.

	11

On September 26, 2013, the Company entered into an Agreement of Sublease with Axcellerate Pharma, LLC (“Axcellerate”), pursuant to which the Company will sublease to Axcellerate a portion of the Company’s premises consisting of approximately 30,000 rentable square feet of the building located at 20 Kingsbridge Road, Piscataway, New Jersey and a share of related parking areas (the “Sublease”).

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Unless the context requires otherwise, references in this Quarterly Report on Form 10-Q to “Enzon,” the “Company,” “we,” “us,” or “our” and similar terms mean Enzon Pharmaceuticals, Inc. and its subsidiaries.

Overview

We receive revenues from existing licensing arrangements with other companies primarily related to sales of six marketed products, namely, PegIntron ^® , Sylatron ^® , Macugen ^® , CIMZIA ^® , Oncaspar and Adagen. The primary source of our royalty revenue is PegIntron, which is marketed by Merck. We currently have no clinical operations and limited corporate operations.

We were previously dedicated to the research and development of innovative therapeutics for patients with high unmet medical needs. In December 2012, we announced that our Board of Directors retained Lazard Frères & Co. LLC to act as financial advisor in a review of the possible sale or disposition of one or more corporate assets or a sale of our company and that our Board of Directors established a special committee to oversee our sale review process. In connection with our sale review process, we substantially suspended all clinical development activities with a goal of conserving capital and maximizing value returned to our stockholders. In April 2013, the Company announced that it had concluded a thorough review of the possible sale or disposition of one or more corporate assets, or a sale of the Company. The review did not result in a definitive offer to acquire the Company or all or substantially all of the Company’s assets. In the same announcement, the Company also announced that its Board of Directors intends to distribute excess cash, expected to arise from ongoing royalty revenues, in the form of periodic dividends to stockholders.

	12

On April 30, 2013, pursuant to the terms of an asset purchase agreement entered into on the same date (the “Belrose APA”), we completed the sale of all of our right, title and interest in our Customized PEGylation Linker Technology platform and related assets to Belrose Pharma Inc. (“Belrose”) for aggregate consideration of $700,000. The assets sold included (i) intellectual property and know-how associated with the PEGylation platform (including certain patents), (ii) patents and know-how related to PEG-SN38, (iii) patents and know-how associated with certain of our internal clinical programs and (iv) certain related supplies and equipment. In addition, we assigned to Belrose our existing license agreement with Zhejiang Hisun Pharmaceutical Co., Ltd. The Belrose APA had also provided for the sale by us of our interest in the Locked Nucleic Acid (LNA) Technology platform and related assets for $100,000 at a second closing; however, the conditions to the second closing were not satisfied. The Belrose APA also entitles us to receive from Belrose additional potential payments, including a share of net revenues that may be received from Hisun related to PEG-SN38 rights in China as well as a share of other potential partnering revenues. The achievement of any of these potential payments is uncertain. The assets sold to Belrose did not include any of the Company’s existing rights to receive royalties on PegIntron®, Sylatron®, Macugen®, CIMZIA®, OMONTYS®, Oncaspar or Adagen.

On September 26, 2013, the Company entered into an Agreement of Sublease with Axcellerate Pharma, LLC (“Axcellerate”), pursuant to which the Company will sublease to Axcellerate a portion of the Company’s premises consisting of approximately 30,000 rentable square feet of the building located at 20 Kingsbridge Road, Piscataway, New Jersey and a share of related parking areas (the “Sublease”). The Company’s premises located at 20 Kingsbridge Road, Piscataway, New Jersey are currently leased by the Company pursuant to an agreement of lease dated as of April 1, 1995, as amended by that certain First Amendment to Lease dated as of November 13, 2001 (the “Prime Lease”), with BDG Kingsbridge L.L.C., predecessor-in-interest to Kingsbridge 2005, LLC (“Prime Landlord”). The Sublease is subject to the Company’s receipt of the Prime Landlord’s consent to the Sublease. The term of the Sublease will commence on the date that the Company has received the Prime Landlord’s consent to the Sublease and will expire on July 30, 2021, which is one day prior to the expiration of the Prime Lease. The rights of Axcellerate under the Sublease will be subject to the terms of the Prime Lease. The monthly fixed rent payable by Axcellerate under the Sublease will be as follows: (i) in year one, $10,417, (ii) in year two, $15,625, (iii) in year three, $20,833, (iv) in year four, $26,042 and (v) in each of years five through eight, $35,000. The Sublease also provides for Axcellerate to pay additional rent to cover its applicable share of real estate taxes, operating expenses, sewer and gas usage, water usage, electricity usage and certain other charges incurred by Axcellerate.

We have no intention of resuming any clinical development activities.

Throughout Management’s Discussion and Analysis, the primary focus is on the results of operations, cash flows, financial condition and future outlook of our business. The percentage changes throughout the following discussion are based on amounts stated in thousands of dollars and not the rounded millions of dollars reflected in this section.

We receive income from royalties on sales of products by other companies that use our proprietary PEGylation technology, including PegIntron, marketed by Merck; Macugen, marketed by Pfizer, Inc. outside the U.S. and Valeant Pharmaceuticals International, Inc. in the U.S.; and CIMZIA, marketed by UCB Pharma. Notification from the third-party licensee of the royalties earned under the license agreement is the basis for royalty revenue recognition. This information generally is received from the licensees, and royalty revenue is recognized, in the quarter subsequent to the period in which the sales occur. Royalty revenue for the three months ended September 30, 2013 decreased 19% to $8.8 million from $10.9 million for the three months ended September 30, 2012. For the nine months ended September 30, 2013, royalty revenue decreased 15% to $26.4 million from $31.0 million for the nine months ended September 30, 2012, primarily due to declining sales of PegIntron related to changes in the hepatitis market. The Company believes that the sales declines are attributable in part to patient treatment being delayed by health care providers in anticipation of new therapeutic options becoming available.

Sales of PegIntron by Merck continue to constitute the most significant source of our royalty revenue. The following table summarizes our PegIntron royalties earned (in millions of dollars):

	Three Months Ended								Nine Months Ended
	September 30,				Dollar		Percent		September 30,				Dollar		Percent
PEGINTRON royalties from:	2013		2012		Change		Change		2013		2012		Change		Change

Contract Research and Development

Pursuant to a transition services agreement entered into at the time of the sale of our former specialty pharmaceutical business, we began performing product-support research and development, consulting and technology transfer functions for the purchaser effective with the close of the sale transaction on January 29, 2010. The transition services associated with product-support research and development were reported in continuing operations due to our ongoing involvement in the research and development related to the divested products. No revenue was generated from these services for the three and nine months ended September 30, 2013, and we will not generate any such revenue in the future. This compares to minimal revenue reported for the three and nine months ended September 30, 2012. Our contractual obligation was to assist with these transition services for a period of up to three years subsequent to the date of the sale, although the level of such activity declined significantly during 2012. The transition services agreement was terminated by the purchaser on September 30, 2012.

Miscellaneous Revenue

Miscellaneous revenue was $0.6 million for the nine months ended September 30, 2013. In the three months ended March 31, 2013, the Company recorded miscellaneous revenue of $0.55 million representing a milestone event related to the licensing of PEG-SN38 as part of the Collaboration Agreement with Hisun. Hisun has not paid this milestone payment and the Company has determined that there is substantial doubt as to whether it will be paid, resulting in the $0.55 million provision for bad debts. The Company is continuing to negotiate with Hisun to reach a resolution to this matter.

In addition, miscellaneous revenue consists of rental receipts from the sublease of unused manufacturing and excess office space for which we no longer have lease commitments. The underlying lease expense is reflected in general and administrative expenses.

During the third quarter of 2013, total spending on our research and development programs decreased by $3.3 million, or 84%, to $0.6 million compared to $3.9 million for the third quarter of 2012. Research and development expense in the third quarter primarily comprised the $0.5 million charge related to the Santaris termination. Clinical development expenses declined by $0.5 million and salaries and benefits expenses declined by $1.5 million as a result of the restructuring implemented in the first half of 2013. Clinical development expenses have declined for the three months ended September 30, 2013 compared to the same three month period of 2012 due to the Company substantially suspending all clinical development activities.

During the first nine months of 2013, total spending on our research and development programs decreased by $14.0 million, or 85%, to $2.5 million compared to $16.5 million for the first nine months of 2012.

Interest expense was $2.1 million for the first nine months of 2013 versus $4.1 million for the first nine months of 2012. From November 2011 to May 2012, we repurchased $18.7 million in principal amount of our 4% convertible notes, and the declining interest costs are reflective of the lower principal amounts outstanding. Additionally, the Company retired the 4% convertible notes during the second quarter of 2013.

Liquidity and Capital Resources

We had cash and cash equivalents of $21.7 million and no marketable securities as of September 30, 2013, as compared to cash, cash equivalents and marketable securities of $196.7 million as of December 31, 2012. The decrease in cash, cash equivalents and marketable securities was primarily attributable to net cash used in financing activities of $186 million, which was attributable to $70.0 million used to pay the June 2013 special cash dividend and $115.8 million used to retire the outstanding principal amount of our 4% convertible notes which matured during June 2013.

For the nine months ended September 30, 2013, net cash provided by operating activities was $10.1 million compared to $2.0 million of net cash provided by operating activities for the nine months ended September 30, 2012.

In the first nine months of 2013, the net cash provided by investing activities was $120.3 million. We sold marketable debt securities to generate cash to pay the June 2013 special cash dividend and to retire the outstanding principal amount of our 4% convertible notes during the second quarter of 2013.

Net cash provided in investing activities was $69.9 million in the first nine months of 2012 as we sold marketable debt securities with a view toward shortening the duration of our portfolio.

Net cash used in financing activities was $186.0 million for the first nine months of 2013 versus $35.3 million net cash used in financing activities for the first nine months of 2012. During the first nine months of 2013, we utilized $70.0 million to pay the special cash dividend in June 2013 and $115.8 million to retire the principal amount of our outstanding 4% convertible notes which matured during June 2013.

In December 21, 2010, our Board of Directors had authorized a share repurchase program under which we are authorized to repurchase up to $200.0 million of our outstanding common stock. Since the inception of this share repurchase program, the cumulative number of shares repurchased and retired through September 30, 2013 amounts to 16,174,568 shares at a total cost of $153.4 million, or an average cost per share of approximately $9.48. We have suspended repurchases under the share repurchase program.

Our current sources of liquidity are (i) cash, (ii) cash equivalents and (iii) royalties (primarily those related to sales of PegIntron).

Based upon our current sources of liquidity, we anticipate our cash and cash equivalents will be sufficient to meet our capital and operational requirements for the near future.

Off-Balance Sheet Arrangements

As part of our ongoing business, we do not participate in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities (SPEs), which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually limited purposes. As of September 30, 2013, we were not involved in any SPE transactions.

Contractual Obligations

Our major outstanding contractual obligations relate to our operating leases and license agreements with collaborative partners. The Company retired its 4% convertible notes during the second quarter of 2013.

Critical Accounting Policies and Estimates

A critical accounting policy is one that is both important to the portrayal of a company’s financial condition and results of operations and requires management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

Our consolidated financial statements are presented in accordance with accounting principles that are generally accepted in the U.S. All applicable U.S. GAAP accounting standards effective as of September 30, 2013 have been taken into consideration in preparing the consolidated financial statements. The preparation of the consolidated financial statements requires estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. Some of those estimates are subjective and complex, and, consequently, actual results could differ from those estimates. The following accounting policies and estimates have been highlighted as significant because changes to certain judgments and assumptions inherent in these policies could affect our consolidated financial statements.

We base our estimates, to the extent possible, on historical experience. Historical information is modified as appropriate based on current business factors and various assumptions that we believe are necessary to form a basis for making judgments about the carrying value of assets and liabilities. We evaluate our estimates on an ongoing basis and make changes when necessary. Actual results could differ from our estimates.

Revenues

Royalties under our license agreements with third-parties and pursuant to the sale of our former specialty pharmaceutical business are recognized when reasonably determinable and earned through the sale of the product by the third-party and collection is reasonably assured. Notification from the third-party licensee of the royalties earned under the license agreement is the basis for royalty revenue recognition. This information generally is received from the licensees in the quarter subsequent to the period in which the sales occur.

	17

Contingent payments due under the asset purchase agreement related to the sale of our former specialty pharmaceutical business are recognized as income when the milestone has been achieved and collection is assured. Such payments are non-refundable, and no further effort is required on the part of the Company or the other party to complete the earning process. Non-refundable payments received upon entering into license and other collaborative agreements where we have continuing involvement are recorded as deferred revenue and recognized ratably over the estimated service period.

Research and Development Expenses

We accrued expenses for the cost of work performed by contract research organizations, contract manufacturing organizations and others based upon the estimated amount of the total effort completed on each order, study or project using factors such as the number of lots produced, the number of patients enrolled, the number of active clinical sites and the duration for which the patients are enrolled in the study. We base the estimates on the information available at the time. Additional information may become available at a later date that would enable us to develop a more accurate estimate. Such changes in estimate are generally recognized in the period when the information is first known.

Income Taxes

Under the asset and liability method of accounting for income taxes, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance on net deferred tax assets is provided for when it is more likely than not some portion or all of the deferred tax assets will not be realized. As of September 30, 2013, we believe that it is more likely than not that our net deferred tax assets, including our net operating losses from operating activities and stock option exercises, will not be realized within the next twelve months. We recognize the benefit of an uncertain tax position that we have taken or expect to take on the income tax returns we file if it is more likely than not we will be able to sustain our position.

Stock-Based Compensation

The Company recognizes the cost of all share-based payment transactions at fair value. Compensation cost, measured by the fair value of the equity instruments issued, adjusted for estimated forfeitures, is recognized in the financial statements as the respective awards are earned.

The impact that share-based payment awards will have on the Company’s results of operations is a function of the number of shares awarded, the trading price of the Company’s stock at date of grant or modification and vesting, including the likelihood of achieving performance goals. Furthermore, the application of the Black-Scholes valuation model employs weighted average assumptions for expected volatility of the Company’s stock, expected term until exercise of the options, the risk free interest rate, and dividends, if any to determine fair value. Expected volatility is based on historical volatility of the Company’s common stock; the expected term until exercise represents the weighted average period of time that options granted are expected to be outstanding giving consideration to vesting schedules and the Company’s historical exercise patterns; and the risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option.

Forward-Looking Information and Factors That May Affect Future Results

This Quarterly Report on Form 10-Q contains forward-looking statements within the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. All statements contained in the Quarterly Report on Form 10-Q, other than statements that are purely historical, are forward-looking statements. Forward-looking statements can be identified by the use of forward-looking terminology such as the words “believes,” “expects,” “may,” “will,” “should,” “potential,” “anticipates,” “plans” or “intends” or the negative thereof, or other variations thereof, or comparable terminology, or by discussions of strategy. Forward-looking statements are based upon management’s present expectations, objectives, anticipations, plans, hopes, beliefs, intentions or strategies regarding the future and are subject to known and unknown risks and uncertainties that could cause actual results, events or developments to be materially different from those indicated in such forward-looking statements, including, but not limited to, the following risks and uncertainties:

· We have limited sources of revenue and there can be no assurance that we will be able to sustain profitability in the future.

· Our financial results are heavily dependent on continued sales of PegIntron and if revenues from these royalties or royalties from the sales of other products materially decline, our results of operations and financial position could be materially harmed.

· The discretion of our Board of Directors to declare dividends and uncertainty regarding the amount and/or timing of excess cash, if any, that will actually be distributed to stockholders.

· Costs associated with workforce reductions and the risk that we may not be able to realize the expected benefits from our recent reductions in our workforce.

· We may outsource certain corporate functions, which could make us more dependent on third-parties to perform these corporate functions.

A more detailed discussion of these risks and uncertainties and other factors that could affect results is contained in our filings with the U.S. Securities and Exchange Commission, including our Annual Report on Form 10-K for the year ended December 31, 2012, as updated in “Item 1A. Risk Factors” of our subsequent quarterly reports on Form 10-Q. These risks and uncertainties and other factors should be considered carefully and readers are cautioned not to place undue reliance on such forward-looking statements. As such, no assurance can be given that the future results covered by the forward-looking statements will be achieved. All information in this Quarterly Report on Form 10-Q is as of the date of this report, unless otherwise indicated, and we undertake no duty to update this information.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Our cash equivalents are primarily held in a number of triple-A rated institutional money market funds. We do not invest in commodities or use financial derivatives for trading purposes. Our market risk exposure consists principally of exposure to changes in interest rates.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, under the direction of our Interim Principal Executive Officer and Interim Chief Operating Officer, acting in his capacity as our Principal Executive Officer and Principal Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of September 30, 2013. Disclosure controls and procedures are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to management, including our Interim Principal Executive Officer and Interim Chief Operating Officer, acting in his capacity as our Principal Executive Officer and Principal Financial Officer, to allow timely decisions regarding required disclosures. During the evaluation of disclosure controls and procedures as of December 31, 2012 conducted during the preparation of the consolidated financial statements, a material weakness in internal control over financial reporting related to non-routine, complex technical accounting matters, specifically impairment analysis of property and equipment was identified . Following the remediation of our review process related to accounting for non-routine complex technical accounting matters , as described more fully below, our Interim Principal Executive Officer and Interim Chief Operating Officer, acting in his capacity as our Principal Executive Officer and Principal Financial Officer, concluded that, as of September 30, 2013, the Company’s disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

In light of the material weakness described above, we have taken steps to remediate our review process related to accounting for non-routine complex technical accounting matters. Management, with the input and oversight of the Audit Committee, implemented the following steps in March 2013: (i) enhancement of our controls related to the preparation of accounting position papers documenting our analysis and conclusions for all complex technical accounting matters and (ii) where appropriate, seeking the advice of qualified outside consultants on the application of U.S. GAAP for such matters.

Based upon these steps taken and our testing and evaluation of the effectiveness of our internal controls, we have concluded the material weakness related to controls over the period-end financial reporting process no longer existed as of March 31, 2013.

There were no changes in our internal control over financial reporting as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during the quarter ended September 30, 2013 that have materially affected, or are reasonably likely to materially affect our internal control over financial reporting.

Part II – OTHER INFORMATION

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.
