(1) Description of Business

Enzon Pharmaceuticals, Inc. and subsidiaries (Enzon or the Company) is a biotechnology company dedicated to the research and development of innovative therapeutics for cancer patients with high unmet medical needs. Operations are funded in part by the receipt of royalty revenues from licensing arrangements with other companies related to sales of products developed using the Company’s proprietary Customized PEGylation Linker Technology (Customized Linker Technology®) – primarily PEGINTRON, marketed by Merck & Co., Inc. 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 almost exclusively in the United States.

The Company’s pipeline drug development programs utilize two platforms – Customized Linker Technology and third-generation messenger ribonucleic acid (mRNA)-targeting agents utilizing the Locked Nucleic Acid (LNA) technology. The Company currently has four compounds in clinical development: PEG-SN38 and the Hypoxia-Inducible Factor-1α (HIF-1α), Survivin and Androgen Receptor (AR) messenger RNA (mRNA) antagonists. In addition, the Company has other novel LNA targets in various stages of preclinical research.

On January 29, 2010, the Company sold its specialty pharmaceutical business, comprised principally of the Company’s products and contract manufacturing segments, for approximately $309 million in cash with the potential for subsequent milestone payments and royalties.

(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 the U.S. Securities and Exchange Commission Regulation S-X. 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 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, 2010.

Principles of Consolidation
The condensed consolidated financial statements include those of Enzon Pharmaceuticals, Inc. and its subsidiaries. All intercompany balances and transactions have been eliminated as part of the consolidation.

Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates include the valuation of certain investments, long-lived assets, legal and contractual contingencies and assumptions used in the calculation of share-based compensation and income taxes. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience, the current economic environment and other factors that management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in estimates will be reflected in the financial statements in future periods. In the opinion of management, all adjustments considered necessary for a fair presentation have been included in these financial statements.

Reclassifications
Certain prior-period amounts have been reclassified to conform to the current period presentation. In 2010, cash flows from discontinued operations were previously included in continuing operations within cash flows from operating and investing activities. The Company has made the appropriate reclassification to the current period presentation of the prior period statement of cash flows. There is no change in either the net cash provided by operating activities or the net cash provided by investing activities to the prior period statement of cash flows, and the reclassification between continuing and discontinued operations in the prior period is not deemed material.

(3) Financial Instruments and Fair Value

The carrying values of cash, cash equivalents, other current assets, accounts payable, and accrued expenses in the Company’s condensed consolidated balance sheets approximated their fair values at June 30, 2011 and December 31, 2010 due to their short-term nature. Short-term investments and marketable securities are carried on the balance sheets at fair value based on quoted market prices. All fair value measures are Level 1. Fair values and carrying amounts of the Company’s financial instruments are indicated below (in thousands):

The amortized cost, gross unrealized holding gains or losses, and fair value of the Company’s investments by major security type at December 31, 2010 were as follows (in thousands):


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


Corporate debt	$	52,079	$	738	$	—		$	52,817
U.S. government-sponsored entities debt		1,000		4		—			1,004
Non-U.S. government debt		5,553		86		—			5,639
Other		3,019		111		(26	)		3,104

	$	61,651	$	939	$	(26	)	$	62,564

* Included in short-term investments of $31,170 and marketable securities of $31,394 at December 31, 2010.

All corporate, U.S. government-sponsored entity and non-U.S. government debt investments are classified as available-for-sale securities. Other securities include investments of participants in the Company’s Executive Deferred Compensation Plan (predominantly mutual fund shares) totaling $3.3 million fair value as of June 30, 2011 and $3.1 million fair value as of December 31, 2010. There is a non-current liability that offsets the aggregate deferred compensation plan assets.

Fair value is determined from readily available quoted prices in active markets (Level 1, the preferred approach pursuant to applicable accounting guidance). As of June 30, 2011 and December 31, 2010, the Company’s short-term investments and marketable securities are all valued based on Level 1 inputs.

ENZON PHARMACEUTICALS, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(Unaudited)

Maturities of marketable debt securities, excluding securities related to the Company’s Executive Deferred Compensation Plan, at June 30, 2011 were as follows (in thousands):


Twelve-Month Periods Ending June 30,	Amortized Cost		Fair Value


2012	$	40,593	$	41,083

Sales during the quarter ended June 30, 2011 of investments in the deferred compensation plan resulted in a realized gain of approximately $58,000, bringing the year-to-date total realized gains to approximately $80,000. However, because the Company maintains a liability for the fair value of the deferred compensation due to plan participants, any realized gains or losses related to these investment holdings are off-set by a corresponding increase or decrease in the liability to operating expenses. Realized gains and losses on sales are computed on the basis of specific identification of the securities sold.

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 June 30, 2011, only certain assets of the Company’s Executive Deferred Compensation Plan have unrealized holding losses. None of the underlying investments has been in a continuous loss position longer than twelve months.

(5) Notes Payable

The 4% convertible senior notes mature on June 1, 2013 unless earlier redeemed, repurchased or converted. The 4% notes are senior unsecured obligations and rank equal to all future senior unsecured debt of the Company. The 4% notes are convertible at the option of the holders into the Company’s common stock at a conversion price of $9.55 per share (104.712 shares per $1,000 of principal amount). If the closing price of the Company’s common stock for at least 20 trading days in the 30-consecutive-trading-day period ending on the date one day prior to the date of a notice of redemption is greater than 140 percent of the applicable conversion price on the date of such notice, the Company, at its option, may redeem the 4% notes in whole or in part, at a redemption price in cash equal to 100 percent of the principal amount of the 4% notes to be redeemed, plus accrued and unpaid interest, if any, to the redemption date. Upon occurrence of a “fundamental change,” as defined in the indenture governing the 4% notes, holders of the notes may require the Company to redeem the notes at a price equal to 100 percent of the principal amount plus accrued and unpaid interest or, in certain cases, to convert the notes at an increased conversion rate based on the price paid per share of the Company’s common stock in the transaction constituting the fundamental change.

During the first quarter of 2010, notes totaling $115.6 million principal amount were converted into approximately 13.5 million shares of the Company’s common stock, reducing the outstanding principal balance of the notes outstanding to $134.5 million. The net effect of forgone interest and the write-off of deferred debt issuance costs amounted to $0.8 million and was charged to interest expense during the first quarter of 2010 at the time of the notes conversion. The $0.8 million was adjusted in the fourth quarter of 2010 to credit interest expense and charge additional paid-in capital to reflect the capital nature of the transaction. The noncash adjustment was not material to the first or fourth quarters nor to the full year 2010 results of operations.

Interest on the 4% notes is payable on June 1 and December 1 of each year. Accrued interest amounted to $0.4 million as of June 30, 2011 and December 31, 2010.

(6) Stockholders’ Equity

On December 21, 2010, the Company announced a share repurchase program, under which the Company may use up to $200.0 million to purchase the Company’s outstanding common shares. Transactions in the Company’s stock are recorded on a settlement date basis. During the three months ended June 30, 2011, the Company repurchased and retired 5,125,169 shares at a cost of $54.8 million, or an average cost per share of approximately $10.69. This brings the cumulative number of shares repurchased and retired under this program through June 30, 2011 to 9,008,242 shares at a total cost of $96.7 million. The plan continues to be in effect.

⁽¹⁾	Information has not been tax-effected due to an estimated annual effective tax rate of zero.

(8) Supplemental Cash Flow Information

The Company considers all highly liquid investment securities with original maturities of three months or less to be cash equivalents. During the six months ended June 30, 2011, there were payments of interest related to the Company’s 4% notes in the amount of $2.7 million. During the six months ended June 30, 2010, the Company had a noncash conversion of $115.6 million principal amount of the 4% notes into approximately 13.5 million shares of its common stock. This first-quarter conversion resulted in a waiver of accumulated interest which amounted to approximately $0.8 million in interest savings for the Company. Income tax payments were $5,000 and $0.1 million for each of the six month periods ended June 30, 2011 and 2010, respectively.

(9) Sale of In-Process Research and Development

When the Company sold its specialty pharmaceutical business in January 2010, it retained its research and development organization. Prior to the sale, the Company’s research and development function was engaged in, among other things, studies oriented towards the next-generation formulations of Oncaspar and Adagen, two products that were among those sold as part of the specialty pharmaceuticals business. The in-process research and development related to those two products was included in the sale. The $40.9 million selling price was management’s best estimate of its standalone fair value based on the stage of development and consideration of future milestone payments. During the first quarter of 2011, the Company earned a $5.0 million milestone payment from the purchaser of the specialty pharmaceutical business resulting from the approval of a supplemental Biologic License Application (sBLA) for the manufacture of SS Oncaspar.

(10) Loss 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 are not considered to be outstanding shares until the service vesting period has 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, shares issuable under the employee stock purchase plan (ESPP) and the number of shares issuable upon conversion of the Company’s convertible notes payable. In the case of notes payable, the diluted earnings per share calculation is further affected by an add-back of interest to the numerator under the assumption that the interest would not have been incurred if the notes payable were converted into common stock.

These securities could potentially dilute earnings per share in the future. Additionally, without the 4% notes conversion, there is no adjustment to loss from continuing operations for the interest payments that would have been forfeited by the note holders on conversion.

(11) Restructurings

During the second quarter of 2011, the Company recorded a restructuring charge in the amount of $0.7 million for severance payments and benefits related to the departure of the Company’s Executive Vice President, Human Resources & Administration that are payable under the terms of the Severance and Release Agreement. This amount was partially offset by the reversal of an unused restructuring accrual of approximately $61,000 for outplacement services and benefits for former employees. As of June 30, 2011, the entire $0.7 million was included in accrued expenses under current liabilities.

During the first quarter of 2011, the Company recorded a restructuring charge in the amount of $0.4 million related to the excess of committed lease costs over potential sublease income for office space in Bridgewater, New Jersey that was vacated during the quarter when the Company relocated its corporate offices to Piscataway, New Jersey.

A fourth quarter 2010 workforce reduction resulted in an expense of $3.0 million for separation benefits. The affected employees were notified in December 2010, and the majority of the terminations occurred during the first quarter of 2011. Separation payments will be made for up to a year following the respective separations. As of December 31, 2010, the full $3.0 million was an accrued expense, of which $2.7 million was reported as a current liability. The Company made separation payments of $0.4 million and $1.0 million during the first and second quarters of 2011, respectively. As of June 30, 2011, there is $1.6 million remaining in accrued expenses under current liabilities.

During the first quarter of 2010, the Company’s workforce reduction involved 64 employees and resulted in an expense of $6.1 million for separation benefits. These actions related primarily to the sale of the specialty pharmaceutical business and affected employees who were previously engaged in activities related to the divested business but who did not transfer to the employment of the purchaser. These employees were provided with separation benefits after certain transition periods, during which they assisted with an orderly transfer of activities and information to the purchaser. In addition, the Company reassessed its staffing requirements subsequent to the sale in light of the lessened demands on many of its general and administrative functions. As of June 30, 2011, all of the required separation payments have essentially been completed.

Effective February 22, 2010, the Company’s then President and Chief Executive Officer resigned from the Company. For the quarter ended March 31, 2010, the Company expensed $3.8 million for severance payments and benefits that were payable under the terms of this individual’s employment agreement. This amount was reduced during the quarter ended June 30, 2010 by approximately $0.2 million once the termination agreement was executed. Payments due pursuant to the termination agreement were made during the third quarter of 2010.

(12) Share-Based Compensation

Stock Option and Nonvested Share Awards

In May 2011, the Company’s stockholders approved a new share-based compensation plan, the 2011 Stock Option and Incentive Plan, which authorized 5,000,000 new shares of common stock for future issuance under this plan. As of June 30, 2011, awards providing for the issuance of 200,000 shares have been granted under this plan.

For the quarter ended June 30, 2011, the Company recognized share-based compensation expense of $0.7 million. Shares were withheld to pay $0.2 million of taxes on behalf of employees related to share-based compensation resulting in a net incremental credit to additional paid-in capital of $0.5 million. For the quarter ended June 30, 2010, the Company recognized share-based compensation expense of $0.8 million. Shares were withheld to pay $1.4 million of taxes on behalf of employees related to share-based compensation resulting in a net incremental debit to additional paid-in capital of $0.6 million.

During the six months ended June 30, 2011, the Company recognized share-based compensation expense of $1.9 million. Shares were withheld to pay $0.9 million of taxes on behalf of employees related to share-based compensation resulting in a net incremental credit to additional paid-in capital of $1.0 million. During the six months ended June 30, 2010, the Company recognized share-based compensation expense of $5.3 million, of which $0.6 million is included in discontinued operations. Shares were withheld to pay $3.3 million of taxes on behalf of employees related to share-based compensation resulting in a net incremental credit to additional paid-in capital of $2.0 million.

In connection with the sale of the specialty pharmaceutical business, in December 2009 the board of directors of the Company elected to accelerate the vesting of certain share-based awards granted under the Company’s 2001 Incentive Stock Plan as of the consummation of the sale. The acceleration applied to all employees other than executives and members of the board of directors. The acceleration resulted in a noncash expense of $1.0 million in the first quarter of 2010. These charges primarily represent an acceleration of expense recognition pursuant to the original award and, to a lesser extent, an adjustment, in certain cases, to recognize the modification of the award in contemplation of the sale. In addition, certain stock awards granted to the Company’s former President and Chief Executive Officer were subject to accelerated vesting as of the date of termination of his employment in February 2010. The acceleration of vesting of these share-based awards constituted a noncash charge to general and administrative expense in the first quarter 2010 of approximately $2.1 million.

As of June 30, 2011, there was $0.5 million of total unrecognized compensation cost related to unvested options that the Company expects to recognize over a weighted-average period of 17 months and $5.4 million of total unrecognized compensation cost related to nonvested shares to be recognized over a weighted-average period of 27 months.

The weighted average grant price of the options granted during the six months ended June 30, 2011 was $12.00 per share and fair values ranged from $3.13 to $4.41 per share. The aggregate fair value of the options granted during the six months ended June 30, 2011 was $0.7 million. The nonvested shares granted during the six months had a weighted-average grant date fair value of $11.37 per share for an aggregate fair value of $1.9 million. The Company uses historical data to estimate forfeiture rates.

Activity in options and nonvested shares during the six months ended June 30, 2011 and related balances outstanding as of that date are reflected below (in thousands):

(13) Income Taxes

During the three and six months ended June 30, 2011, the Company recorded $5,000 of income tax expense related to the Canadian subsidiary. During the three and six months ended June 30, 2010, the Company recorded a net income tax benefit of $0.2 million consisting principally of a Canadian transfer pricing refund. The Company did not recognize a U.S. Federal income tax provision for the first half of 2011 or 2010 because the estimated annual effective tax rate was zero. The sale of the specialty pharmaceutical business in January 2010, including the sale of in-process research and development, was a taxable transaction for federal income tax purposes, although it resulted in no federal income tax liability due to the tax basis the Company had in divested assets and the net operating loss generated in 2010. As of June 30, 2011, the Company continues to provide a valuation allowance against its net deferred tax assets since the Company believes it is more likely than not its deferred tax assets will not be realized.

(14) Commitments and Contingent Liabilities

The Company has employment and separation agreements with certain members of its management that provide for severance payments and payments following a termination of employment occurring for various reasons, including a change in control of the Company.

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 has non-cancelable lease obligations for certain office and production facilities that have been vacated. Some of these facilities have been sublet, and the Company is actively seeking to sublet the remaining unused space.

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

Overview

We are a biotechnology company dedicated to the research and development of innovative therapeutics for cancer patients with high unmet medical needs. Our Principal Executive Officer reviews our operating results on an aggregate basis and manages the operations as a single operating unit. We currently have four compounds in human clinical development: PEG-SN38, which utilizes our PEGylation technology, and the mRNA antagonists of Hypoxia-Inducible Factor-1α (HIF-1α), Survivin and Androgen Receptor (AR), which utilize the LNA technology. In addition, the Company has other novel LNA targets in various stages of preclinical research. We receive royalty revenues from licensing arrangements with other companies related to sales of products developed using our proprietary Customized Linker Technology – primarily PEGINTRON marketed by Merck & Co., Inc. (Merck).

In order to better focus on our portfolio of innovative oncology programs, we divested our specialty pharmaceutical business comprised principally of what had previously been our Products and Contract Manufacturing segments. Prior to the January 29, 2010 closing of the transaction, we were a biopharmaceutical company involved in the development, manufacture and commercialization of medicines for patients with cancer and other life-threatening conditions. We operated in three business segments: Products, Royalties and Contract Manufacturing. We had a portfolio of four marketed products and manufactured products for other pharmaceutical companies through our contract manufacturing business.

In 2011, we are not influenced so heavily by the restructuring, reorganization and consolidation activities that significantly impacted the Company in 2010. Our results of operations are now expected to be more reflective of our ongoing activities, which are directed towards advancing our research and development pipeline. We have completed enrollment in our Phase II PEG-SN38 metastatic colorectal trial as well as our Phase I HIF-1α clinical trials, and we anticipate completing enrollment in 2011 in our Phase II PEG-SN38 trial in metastatic breast cancer as well as our Phase I clinical trial of Survivin. We intend to continue our efforts to seek a collaborative partnership designed to finance our development activities in the future. The enrollment of patients for clinical trials is an inherently uncertain process and there can be no assurance we will be able to complete the enrollment of patients for our clinical trials within the timeframe anticipated. As we previously disclosed on May 19, 2011, we will discontinue our PEG-SN38 clinical program in metastatic colorectal cancer following conclusion of the Phase II study. During the second quarter of 2011, we decided not to pursue development of three mRNA antagonists and have therefore returned these early stage LNA targets to Santaris in accordance with our license agreement.

Throughout Management’s Discussion and Analysis, the primary focus is on the results of operations, cash flows, financial condition and future outlook of our continuing operations. 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.

Royalty revenue	$	9.2	(13)	$	10.6	$	20.9	(11)	$	23.5

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 Eyetech, 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 in the quarter subsequent to the period in which the sales occur. Royalty revenue for the three months ended June 30, 2011 decreased 13 percent to $9.2 million from $10.6 million for the three months ended June 30, 2010. For the six months ended June 30, 2011, royalty revenue decreased 11 percent to $20.9 million from $23.5 million for the six months ended June 30, 2010. The decline in royalty revenue was primarily attributable to lower sales of PEGINTRON, which continues to constitute the most significant source of our royalty revenues.

As we have previously indicated, based upon information we have reviewed, we believe that a significant number of patients suffering from hepatitis C may be deferring treatment until new therapies become available. In May 2011, the U.S. Food and Drug Administration (“FDA”) approved VICTRELIS^™ (boceprevir), for the treatment of chronic hepatitis C (CHC). VICTRELIS is approved for the treatment of CHC genotype 1 infection, in combination with peginterferon alfa and ribavirin, in adult patients (18 years of age and older) with compensated liver disease, including cirrhosis, who are previously untreated or who have failed previous interferon and ribavirin therapy. In addition, in May 2011, the FDA also approved Incivek (telaprevir) to treat certain adults with chronic hepatitis C infection. Incivek is used for patients who have either not received interferon-based drug therapy for their infection or who have not responded adequately to prior therapies. Incivek is approved for use with interferon therapy made up of peginterferon alfa and ribavirin.

We believe that the approval of these drugs may result in increased sales of PEGINTRON in the future, however we have no clear evidence at this point of what the impact may be, if any, that these new therapies for hepatitis C may have on sales of PEGINTRON.

During the three months ended June 30, 2011, we had royalties on export sales of $8.1 million, of which $2.9 million were in Japan and $2.7 million were in Europe. This compares to $9.0 million of royalties on export sales in the comparable three-month period of 2010, of which $2.9 million were in Japan and $3.4 million were in Europe. On a six-month basis, we had royalties on export sales in 2011 of $17.2 million, of which $6.2 million were in Japan and $5.6 were in Europe, and $19.7 million of royalties on export sales in 2010, of which $6.1 million were in Japan and $6.9 million were in Europe.

Sale of In-process Research and Development

When we sold our specialty pharmaceutical business, we retained our research and development organization. We had been engaged in studies oriented towards the next-generation formulations of Oncaspar and Adagen, two products that were among those sold as part of the specialty pharmaceutical business. The in-process research and development related to Oncaspar and Adagen was sold to the purchaser of the specialty pharmaceutical business and $40.9 million was recognized as revenue in connection with the sale in the first quarter of 2010. The selling price of the in-process research and development represented management’s best estimate of its standalone fair value based on the stage of development and consideration of future milestone payments at that time potentially amounting to $27.0 million. All necessary technology and know-how was transferred to the purchaser at the time of the sale, and the purchaser could resell the in-process research and development asset. At the time of the sale, the activities necessary to complete the work on Oncaspar and Adagen next-generation formulas could have been performed by the purchaser or others.

During the first quarter of 2011, the Company earned a $5.0 million milestone payment from the purchaser of the specialty pharmaceutical business resulting from the approval of a supplemental Biologic License Application (sBLA) for the manufacture of SS Oncaspar. This milestone payment relates to our transfer of technology that was included in the 2010 sale of in-process research and development. During the latter half of 2010, circumstances emerged that caused us to determine that it would be unlikely that we will be able to earn another of the milestones, valued at $5.0 million. Of the remaining $17.0 million of potential milestone payments, it is very unlikely that any will be received in 2011 and there can be no assurance that we will receive any such payments in the future.

Contract Research and Development

During the three months ended June 30, 2011, $0.2 million was earned for contract research and development services. This compares to $2.6 million for the three months ended June 30, 2010. For the six month period ended June 30, 2011, $1.3 million was earned for contract research and development services, compared to $5.2 million for the period from January 29, 2010 through June 30, 2010. Pursuant to a transition services agreement entered into at the time of the sale of the 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 are being reported in continuing operations due to our on-going involvement in the research and development related to the divested products. We are being compensated for this work at actual cost plus a mark-up per the terms of the transition services agreement. Our contractual obligation is to assist with these transition services for a period of up to three years subsequent to the date of the sale, although we anticipate the level of such activity to decline significantly from 2010 levels throughout the remainder of 2011.

Miscellaneous Income

As part of the transition services agreement referred to above, we are being compensated for various general and administrative services provided to the purchaser of the specialty pharmaceutical business. The compensation for this work includes reimbursement of costs incurred plus a mark-up defined in the agreement. The expenses incurred in relation to these services are reported as general and administrative – contracted services. Our involvement in the transitioning of general and administrative activities is essentially complete, and we expect the revenue and associated expenses to be de minimis going forward. During the three months ended June 30, 2011, approximately $54,000 was earned for these services. This compares to approximately $0.5 million for the three months ended June 30, 2010. For the six months ended June 30, 2011, approximately $112,000 was earned for these services, compared to $2.3 million for the period from January 29, 2010 through June 30, 2010.

Also reflected in miscellaneous income are rental receipts from the sublease of unused manufacturing and excess office space for which we have on-going lease commitments. The underlying lease expense is reflected in general and administrative expenses. We received $0.1 million of sublease income during the second quarter of 2011 and $0.3 million for the six months ended June 30, 2011. This compares to $0.1 million during the second quarter of 2010 and $0.1 million for the six months ended June 30, 2010.

Research and development – pipeline. During the second quarter of 2011, total spending on our research and development programs was unchanged at $10.1 million compared to the second quarter of 2010. However, included in the prior year quarter expenses was a $1.0 million milestone payment related to the HER 3 mRNA antagonist. There was no similar milestone payment in the current year quarter. Adjusting for this, spending increased by 10% or $1.0 million quarter over quarter. For the six months ended June 30, 2011, research and development spending was $20.6 million compared to $21.6 million for the first half of 2010. However, included in the first half 2010 expenses was the aforementioned $1.0 million HER 3 mRNA antagonist milestone payment as well as a $1.0 million milestone payment for the beta-catenin mRNA antagonist recorded in the first quarter of 2010. Adjusting for these two milestone payments in the prior year, spending for the current year to date increased by 5% or $1.0 million.

During the second quarter of 2011, we decided not to pursue development of three mRNA antagonists and have therefore returned these early stage LNA targets to Santaris in accordance with our license agreement.

Research and development – specialty and contracted services. As a result of the sale of our specialty pharmaceutical business in January 2010, the programs related to the next-generation Oncaspar and Adagen formulations became the responsibility of the purchaser. We continue to assist in the development of these programs through a transition services arrangement. During the first half of 2011, our spending related to these products decreased substantially, as expected, as the purchaser assumed greater control. These costs amounted to $0.2 million during the second quarter of 2011 and $0.8 million for the six months ended June 30, 2011. Our spending related to these products totaled $1.7 million during the second quarter of 2010 and $4.8 million for the six months ended June 30, 2010.

General and Administrative (millions of dollars):

General and administrative – contracted services	$	0.1	n.m.	$	0.4	$	0.1	n.m.	$	1.8

n.m. – not meaningful

General and administrative. General and administrative expenses declined approximately 20 percent in the second quarter of 2011 to $4.6 million compared to $5.8 million incurred in the second quarter of 2010. For the six months ended June 30, 2011, general and administrative expenses declined approximately 38% to $9.7 million compared to $15.6 million for the first half of 2010. The reduction in our general and administrative expenses is attributable to our efforts to contain costs and to reduce the overhead necessary to support our structure subsequent to the sale of the specialty pharmaceutical business.

Savings to the Company from reductions in staffing and consolidation of facilities are expected to continue over the remainder of 2011. A number of general and administrative positions in human resources, information technology and accounting services that had supported the divested specialty pharmaceutical operations have been eliminated. We have reduced contracted services, accounting and consulting fees from 2010 levels. We have completed the consolidation of our corporate offices from Bridgewater, New Jersey into our Piscataway, New Jersey location in an effort to further reduce costs and improve operating efficiencies. The benefits of these efforts are reflected in our second quarter and year-to-date 2011 operating results. A restructuring program announced in the fourth-quarter 2010 and implemented during the first few months of 2011 is expected to have a further favorable impact on our general and administrative expenses during 2011.

General and administrative – contracted services. As part of the transition services agreement with the purchaser of the specialty pharmaceutical business, we committed to provide certain general and administrative services for a period up to one year subsequent to the sale. We subsequently extended the agreement by ninety days. We were compensated for these services based upon costs incurred plus a mark-up per the terms of the agreement. As expected, the demand for such services from us declined significantly over the course of 2010 and has essentially ceased as of the end of the second quarter of 2011. General and administrative expenses representing transitional services to the purchaser amounted to approximately $0.1 million during the second quarter of 2011 as compared to $0.4 million for the second quarter of 2010. For the six months ended June 30, 2011, these expenses totaled $0.1 million versus $1.8 million for the first half of 2010.

Restructuring

As part of our continued efforts to streamline operations, we undertook reductions in the size of our workforce during the first and fourth quarters of 2010. We also incurred charges related to reductions in leased space at our corporate offices and the write-off of certain related leasehold improvements and furnishings during the second quarter of 2010 and the first quarter of 2011.

During the second quarter of 2011, the Company recorded a net restructuring charge of approximately $0.7 million primarily related to the severance payments and benefits due to the former Executive Vice President, Human Resources & Administration. This was partially offset by the reversal of an unused restructuring accrual for outplacement services for former employees.

During the first quarter of 2011, we completed the planned relocation of our corporate offices from Bridgewater, New Jersey to Piscataway, New Jersey. As a result of having vacated the excess office space in Bridgewater, we incurred a charge during the first quarter of 2011 in the amount of approximately $0.4 million. This amount represents the excess of committed lease costs over potential sublease income. We are actively attempting to sublet the vacated office space.

During the first quarter of 2010, our workforce reduction involved 64 employees and resulted in an expense of $6.1 million for separation benefits. These actions related primarily to the sale of the specialty pharmaceutical business and affected employees who were previously engaged in activities related to the divested business but who did not transfer to the employment of the purchaser. These employees were provided with separation benefits after certain transition periods, during which they assisted with an orderly transfer of activities and information to the purchaser. In addition, we reassessed our staffing requirements subsequent to the sale in light of the lessened demands on many of our general and administrative functions. Effective February 22, 2010, our then President and Chief Executive Officer resigned from the Company. For the quarter ended March 31, 2010, we expensed $3.8 million for severance payments and benefits that were payable under the terms of this individual’s employment agreement. This amount was reduced during the quarter ended June 30, 2010 by approximately $0.2 million once the termination agreement was executed. Payments due pursuant to the termination agreement were made during the third quarter of 2010.

Net investment income was $0.4 million for the second quarter of 2011, as compared to $0.8 million for the second quarter of 2010. For the six months ended June 30, 2011, net investment income was $0.8 million versus $1.8 million for the first half of 2010. The decline reflects the lower balances of investment holdings and a shift to shorter maturity and lower risk investments.

Interest expense was $1.5 million for the three months ended June 30, 2011 and 2010. Interest expense was $3.0 million for the six months ended June 30, 2011 versus $4.2 million for the first half of 2010. The prior year period includes a net effect related to the first quarter 2010 conversion of $115.6 million principal amount of our 4% notes subsequent to the sale of our specialty pharmaceutical business. The net effect of forgone interest and the write-off of a pro rata amount of deferred debt issuance costs amounted to $0.8 million and was charged to interest expense during the first quarter of 2010 at the time of the notes conversion. The $0.8 million was adjusted in the fourth quarter of 2010 to credit interest expense and charge additional paid-in capital to reflect the capital nature of the transaction. The noncash adjustment was not material to the first or fourth quarters nor to the full year 2010 results of operations. Additionally, the decline in interest expense is attributable to lower principal amounts outstanding in 2011 compared to 2010.

Income taxes

Discontinued operations

The cash proceeds received from the sale of the specialty pharmaceutical business, including a second-quarter 2010 working capital adjustment, amounted to approximately $309.0 million. Of this amount, $40.9 million was allocated to the sale of in-process research and development and included in continuing operations. The net proceeds then attributable to discontinued operations yielded a gain of $175.4 million. The results of operations of the specialty pharmaceutical business for the period in January 2010 preceding the sale amounted to income of $3.6 million comprising the remainder of the $179.0 reported in 2010 as income and gain from discontinued operations. The gain from discontinued operations was subsequently adjusted to $176.4 million in the fourth quarter of 2010 to recognize $1.0 million of currency translation gains that had been included in accumulated other comprehensive income but should have been recognized as part of the gain on sale.

Liquidity and Capital Resources

Total cash reserves, which include cash, cash equivalents, short-term investments and marketable securities, were $362.3 million as of June 30, 2011, as compared to $460.1 million as of December 31, 2010. The decrease was primarily attributable to the Company’s share repurchase program.

For the six months ended June 30, 2011, cash used in operating activities of continuing operations was $5.0 million compared to $40.0 million of cash provided in the first half of 2010. The Company incurred a loss from continuing operations of $6.6 million in the first half of 2011. Adjustments for non-cash expenses and changes in various working capital accounts comprised the partially offsetting $1.6 million. The $40.0 million provided in the first half of 2010 was primarily attributable to the Company’s sale of in-process research and development.

Investing activities generated approximately $16.8 million of cash in the first half of 2011 primarily from maturities of marketable securities. This compares to $304.6 million of cash provided by investing activities during the first half of 2010, which was primarily attributable to the $262.6 million net proceeds from the January 2010 sale of the specialty pharmaceutical business (exclusive of the amount apportioned to the sale of in-process research and development reported in operating revenue) and $44 million from sales and maturities of marketable securities.

Net cash used in financing activities was $91.4 million in the first half of 2011 versus $3.7 million provided in the first half of 2010. During the first half of 2011, we utilized $96.3 million to repurchase shares of the Company’s common stock on the open market as part of the program to repurchase up to $200.0 million of common stock initiated in December of 2010. Fees of approximately $0.3 million incurred to purchase the shares were reflected in cash flows from operating activities. The share repurchase program is designed as a means by which to return to shareholders value derived from the sale of the specialty pharmaceutical business.

As of June 30, 2011, we had outstanding $134.5 million of convertible senior notes that mature on June 1, 2013 and bear interest at an annual rate of 4%. Interest is payable on June 1 and December 1 for the 4% notes. Accrued interest on the notes was $0.4 million as of June 30, 2011 and December 31, 2010.

Our current sources of liquidity are our cash reserves, interest earned on such cash reserves, and royalties earned - primarily related to sales of PEGINTRON. Based upon our current planned research and development activities and related costs, our current sources of liquidity, and additional purchases of our outstanding stock which may be made under our share repurchase program, we anticipate our current cash reserves will be sufficient to meet our capital and operational requirements for the near future. While we believe that our current sources of liquidity will be adequate to satisfy our capital and operational needs for the near future, it is likely that we will need to obtain additional financing or enter into a collaborative arrangement to sustain our research and development efforts prior to the time we are able to commercialize any of our product candidates. There can be no assurance, however, that we will be able to obtain additional funds or engage a collaborator on acceptable terms, if at all. If we are unable to obtain adequate financing or collaborative support, we may be required to curtail our research and development activities and/or license our product candidates to third parties on terms that are not favorable to us.

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 (SPE), which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually limited purposes. As of June 30, 2011, we were not involved in any SPE transactions.

Our 4% notes payable are convertible into shares of our common stock at a conversion price of $9.55 per share and pose a reasonable likelihood of potential significant dilution. As of June 30, 2011, the maximum potential dilutive effect of conversion of the 4% notes is approximately 14.1 million shares using the conversion rate of 104.712 shares per $1,000 principal amount currently in effect. If we were to experience a fundamental change as defined in the indenture agreement, the conversion rate could be enhanced for the benefit of the note holders which would yield greater dilution. Notes payable are discussed in greater detail in Liquidity and Capital Resources above and in the notes to our condensed consolidated financial statements.

In addition, stock options to purchase 3.2 million shares of our common stock at a weighted average exercise price of $13.05 per share and 0.6 million restricted stock units were outstanding at June 30, 2011, which represent additional potential dilution.

Contractual Obligations

Our major outstanding contractual obligations relate to our operating leases, convertible debt, and license agreements with collaborative partners. There have been no material changes since December 31, 2010 with respect to our contractual obligations.

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 condensed consolidated financial statements are presented in accordance with U.S. GAAP. All professional accounting standards effective as of June 30, 2011 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. 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. The following accounting policies have been highlighted as significant because changes to certain judgments and assumptions inherent in these policies could affect our consolidated financial statements.

Revenues

Royalties under our license agreements with third-parties and pursuant to the sale of our 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.

Contingent payments due under the asset purchase agreement related to the sale of the 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.

The sale of the specialty pharmaceutical business involved the application of guidance regarding multiple deliverables in separating the revenues associated with the sale of in-process research and development from the other elements of the transaction, namely the assets sold as part of discontinued operations and our continuing involvement in contract research activities. We determined that the in-process research and development had value to the buyer of the specialty pharmaceutical business on a stand-alone basis and that there was objective and reliable evidence available to support the allocation of the total purchase price to the respective units of accounting.

Research and Development Expenses

We accrue expenses for costs for 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 number of lots produced, number of patients enrolled, the number of active clinical sites and the duration for which the patients will be enrolled in the study. We base the estimates on the information available at the time. Additional information may come 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 realized. A valuation allowance 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 June 30, 2011, we believe, based on future projections, that it is more likely than not that our net deferred tax assets will not be realized. 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.

Share-Based Payment

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 our results of operations is a function of the number of shares awarded, vesting and the trading price and fair value of our stock at date of grant or modification. Fair value of share-based payments is determined using the Black-Scholes valuation model which employs weighted average assumptions for expected volatility of our stock, expected term until exercise of the options, the risk free interest rate, and dividends, if any. Expected volatility is based on our historical stock price information.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

The majority of our holdings of financial instruments consist of money market funds, classified as cash equivalents, and debt instruments, classified as available-for-sale securities. Apart from custodial accounts related to the Executive Deferred Compensation Plan, we do not invest in portfolio equity securities. We do not invest in commodities or use financial derivatives for trading purposes. We seek reasonable assuredness of the safety of principal and market liquidity by investing in rated fixed income securities while at the same time seeking to achieve a favorable rate of return. Our market risk exposure consists principally of exposure to changes in interest rates. Our holdings are also exposed to the risks of changes in the credit quality of issuers the majority of which are rated A1 or better. We typically invest the majority of our investments in the shorter-end of the maturity spectrum. Cash equivalents are primarily held in a number of AAA-rated institutional money market funds as well as several corporate and U.S. government-sponsored entities’ debt securities.

The table below presents the principal amounts and related weighted-average coupon rates of our marketable debt securities, excluding those related to our Executive Deferred Compensation Plan, by year of maturity (twelve-month intervals ending June 30 of the year indicated) as of June 30, 2011 (in thousands):


	2012			Fair Value

Fixed Rate	$	40,000		$	41,083
Average Interest Rate		5.00	%

	$	40,000		$	41,083

Our convertible senior unsecured notes have fixed interest rates. Accordingly, the quoted fair values of our notes will fluctuate as market rates of interest rise or fall. Fair values are also affected by changes in the price of our common stock. Our 4% Convertible Senior Notes in the principal amount of $134.5 million at June 30, 2011 are due June 1, 2013 and have a fair value of $160.8 million at June 30, 2011.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, under the direction of our Chief Operating Officer and Chief 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 June 30, 2011. Based on the evaluation, our Chief Operating Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of June 30, 2011.

Changes in Internal Controls

There were no changes in our internal controls over financial reporting as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during the period covered by this report that have materially affected, or are reasonably likely to materially affect our internal control over financial reporting.
