1. Business Organization and Basis of Presentation

Description of the Business

Sucampo Pharmaceuticals, Inc., or the Company, is a global pharmaceutical company focused on innovative research, discovery, development and commercialization of proprietary drugs based on prostones and other novel drug technologies. The therapeutic potential of prostones was first discovered by the Company’s co-founder, Dr. Ryuji Ueno, and under his leadership the Company has pioneered the field of prostones. Prostones are naturally occurring fatty acid metabolites. Originally thought to be biologically inert, prostones have emerged as a promising compound class with unique physiological activities which can be targeted for the treatment of unmet or underserved medical needs.

Prostones act locally to restore normal function in cells and tissues. They are rapidly metabolized to an inactive form, thus when targeted to specific organs and tissues they have local pharmacologic activity avoiding systemic effects. Prostones possess a unique mechanism of action as highly potent and selective ion channel activators. Ion channels are integral parts of cell membranes that regulate the flow of specific ions into and out of cells. This regulation is key to the functioning of cells, such as metabolic processes and cell survival. As such, prostones are physiological mediators of the restoration of cellular homeostasis and tissue regeneration. There is also evidence that prostones have anti-inflammatory properties and can prevent cell death.

The Company’s prostone-based compounds target the ClC-2 and big potassium, or BK, ion channels. Because these ion channels play an important role in physiology, targeted dosing of prostones may have broad applicability in many disease states in different organ systems. The Company has developed synthetic analogs of the naturally occurring prostones, which have been optimized to be more potent, selective, and stable, thus enabling their use as drugs. Prostones are very selective for their molecular targets, and the approved prostone-based compounds are well-tolerated and generally safe.

The Company is focused on developing prostones to treat gastrointestinal, ophthalmic, neurologic, and oncology-based inflammatory disorders, and is also considering other potential therapeutic applications of the Company’s drug platform.

The Company currently generates revenue mainly from product royalties, development milestone payments, clinical development activities and product sales. The Company expects to continue to incur significant expenses for the next several years as the Company continues its research and development activities, seeks regulatory approvals and additional indications for AMITIZA^® (lubiprostone), RESCULA^® (unoprostone isopropyl) and other compounds, and commercializes the Company’s approved products on a global basis.

To date, two prostone products-, AMITIZA and RESCULA, have received marketing approval globally. A third prostone, cobiprostone, or SPI-8811, is in phase 1 clinical development for the target indication of prevention of oral mucositis, or OM. Two additional prostones, SPI-017 and SPI-3608, have also been developed for human testing for the indication of management of pain caused by spinal stenosis, and SPI-017 is currently in a phase 2A trial that is expected to conclude by the fourth quarter of 2013.

AMITIZA is currently being marketed in the United States for two gastrointestinal indications under the October 2004 collaboration and license agreement with Takeda Pharmaceutical Company Limited, or the Takeda Agreement. AMITIZA will be marketed under the Takeda Agreement for a third gastrointestinal indication in the second quarter of 2013. These indications are chronic idiopathic constipation, or CIC, in adults; irritable bowel syndrome with constipation, or IBS-C, in adult women; and opioid-induced constipation, or OIC, in adult patients with chronic, non-cancer pain, which received approval from the FDA in April 2013. AMITIZA at dosage strength of 24 micrograms twice daily is the first and only oral medication for the treatment of OIC in adult patients with chronic, non-cancer pain. Takeda also holds marketing rights to AMITIZA in Canada, but has yet to commercialize in that market. The Company is primarily responsible for development activities under the Takeda Agreement while Takeda is responsible for commercialization of AMITIZA in the United States and Canada. The Company and Takeda initiated commercial sales of AMITIZA in the United States for the treatment of CIC in April 2006 and for the treatment of IBS-C in May 2008.

In Japan, AMITIZA is currently marketed under a license, commercialization and supply agreement, or the Abbott Agreement, with Abbott Japan Co. Ltd., or Abbott, for the gastrointestinal indication of chronic constipation, or CC, excluding constipation caused by organic diseases. Abbott initiated commercial sales of AMITIZA in Japan for the treatment of CC in November 2012.

In the United Kingdom, the Company is currently working to achieve National Institute for Health and Care Excellence, or NICE, endorsement and launch in the United Kingdom in 2013. In Switzerland, the Company is actively marketing AMITIZA, following an agreement on a reimbursement price with the Swiss Bundesamt für Gesundheit (BAG) in December 2012. AMITIZA has also been made available through a Named Patient Program throughout the European Union, Iceland and Norway since February 2012.

SUCAMPO PHARMACEUTICALS, INC.

Notes to Condensed Consolidated Financial Statements (Unaudited) – (Continued)

In the first quarter of 2013, the Company commenced the approval process in other European Union countries for CIC via the Mutual Recognition Procedure, or MRP and filed for the OIC indication in the United Kingdom and Switzerland. If the Company receives approval for OIC in the United Kingdom, the Company will seek approval in other European Union countries following the MRP for OIC.

The Company holds license agreements for RESCULA in the United States and Canada and the rest of the world, with the exception of Japan, Korea, Taiwan and the People’s Republic of China. The Company has begun commercializing RESCULA (unoprostone isopropyl ophthalmic solution) 0.15% for the lowering of intraocular pressure, or IOP, in patients with open-angle glaucoma or ocular hypertension. According to the approved product labeling, RESCULA may be used as a first-line agent or concomitantly with other topical ophthalmic drug products to lower intraocular pressure. RESCULA is a BK channel activator, and thus acts via a mechanism of action, entirely different from any other IOP lowering agent on the market.

In other areas of development, the Company entered into agreements in 2011 with CuroNZ of New Zealand, with the aim to augment the Company’s ophthalmic development opportunities. In the first quarter of 2013, the Company decided to no longer support the development of the peptide compound. Additionally, in 2011, the Company entered into an agreement with Numab AG, or Numab, of Switzerland, to obtain access to their proprietary technology for the discovery of high-affinity antibodies against certain selected targets. In the first quarter of 2013, the Company decided to no longer pursue the further development of the target.

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP, and the rules and regulations of the Securities and Exchange Commission, or SEC, for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s Consolidated Financial Statements as of and for the year ended December 31, 2012 included in the Company’s Annual Report on Form 10-K, which was filed with the SEC on March 18, 2013. The financial information as of March 31, 2013 and for the three months ended March 31, 2013 and 2012 is unaudited. In the opinion of the Company’s management, all adjustments, consisting only of normal recurring adjustments or accruals, considered necessary for a fair statement of the results of these interim periods have been included. The results of the Company’s operations for any interim period are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year.

The Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company balances and transactions have been eliminated.

The preparation of financial statements in conformity with GAAP requires management to make estimates that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

2. Summary of Significant Accounting Policies

Cash and Cash Equivalents

For the purpose of the Condensed Consolidated Balance Sheets and Statements of Cash Flows, cash equivalents include all highly liquid investments with a maturity of 90 days or less at the time of purchase.

Restricted Cash

Restricted cash consists of approximately $28.4 million and $18.9 million at March 31, 2013 and December 31, 2012, respectively. Restricted cash represents cash required to be deposited with certain financial institutions in connection with a loan agreement with The Bank of Tokyo-Mitsubishi UFJ, Ltd., a loan agreement with Mizuho Bank, Ltd., Numab’s loan with Zurcher Kantonalbank and operating leases.

SUCAMPO PHARMACEUTICALS, INC.

Notes to Condensed Consolidated Financial Statements (Unaudited) – (Continued)

Current and Non-current Investments

Current and non-current investments consist primarily of United States government agency securities, certificates of deposits and variable rate demand notes. The Company classifies its investments into current and non-current based on their maturities and management’s reasonable expectation to realize these investments in cash. The Company classifies all of its investments as available for sale securities and reports unrealized gains or losses, net of related tax effects, in other comprehensive income.

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, which include cash and cash equivalents, restricted cash, current and non-current investments, receivables, accounts payable and accrued expenses, approximate their fair values based on their short maturities, independent valuations or internal assessments. The carrying amount of the notes payable at March 31, 2013 was less than the estimated fair value and at December 31, 2012 approximated its fair value. The Company’s debt is subject to the fair value disclosure requirements as discussed in Note 4 below, is considered a Level 2 security.

Accounts Receivable and Unbilled Accounts Receivable

Accounts receivable represent mainly amounts due under the Takeda and the Abbott Agreements. Unbilled accounts receivable represent the research and development expenses that are reimbursable by Takeda but have not been billed to Takeda as of the balance sheet date. The Company recorded an allowance for doubtful accounts at March 31, 2013 and December 31, 2012 of approximately $354,000 and $280,000, respectively, related to certain disputed Takeda invoices.

Product Royalties Receivable

Product royalties receivable represent amounts due from Takeda for the Company’s royalties on sales of AMITIZA, which are based on reports obtained directly from Takeda.

Revenue Recognition

The Company’s revenues are derived primarily from collaboration and license agreements and include upfront payments, development milestone payments, reimbursements of development and co-promotion costs, product sales and product royalties.

Research and Development Revenue

The Company evaluated the multiple deliverables within the collaboration and license agreements in accordance with the guidance of multiple deliverables to determine whether the delivered elements that are the obligation of the Company have value to other parties to the agreement on a stand-alone basis and whether objective reliable evidence of fair value of the undelivered items exists. Deliverables that meet these criteria are considered a separate unit of accounting. Deliverables that do not meet these criteria are combined and accounted for as a single unit of accounting. The appropriate recognition of revenue is then applied to each separate unit of accounting. The Company’s deliverables under the Takeda Agreement and the Abbott Agreement, including the related rights and obligations, contractual cash flows and performance periods, are more fully described in Note 10 below.

Product Royalty Revenue

Royalty revenues are based on net sales of licensed products and are recorded on the accrual basis when earned in accordance with contractual terms when third-party results are reliably measurable, collectability is reasonably assured and all other revenue recognition criteria are met.

Product Sales Revenue

AMITIZA product sales consist of AMITIZA sales to Abbott in Japan. Revenue from AMITIZA product sales is recognized when persuasive evidence of an arrangement exists, delivery has occurred and title to product and associated risk of loss have passed to the customer, the price is fixed or determinable, and collection from the customer is reasonably assured. The Company did not record sales deductions and returns for sales of AMITIZA to Abbott due to the absence of discounts and rebates and no right of return under the contract with Abbott.

7

SUCAMPO PHARMACEUTICALS, INC.

Notes to Condensed Consolidated Financial Statements (Unaudited) – (Continued)

RESCULA product sales consist of RESCULA sales in the United States. The Company recognizes revenue from RESCULA product sales less deductions for estimated sales discounts and sales returns. Revenue from product sales of RESCULA is recognized when persuasive evidence of an arrangement exists, title passes, the price is fixed or determinable, and collectability is reasonably assured. The Company accounts for rebates to certain governmental agencies as a reduction of product sales. The Company allows customers to return product within a specified time period prior to and subsequent to the product’s labeled expiration date. As a result, the Company estimates an accrual for product returns, which is recorded as a reduction of product sales. Given the Company’s limited history of selling RESCULA and the return period, the Company cannot reasonably estimate product returns from the wholesale distribution channel. Therefore the Company is deferring the recognition of revenue until there is confirmation of pull through sales to pharmacies or other end user customers. We will continue to defer recognition until the point at which we have obtained sufficient sales history to reasonably estimate returns from the wholesalers. Our three largest wholesale customers accounted for 89.9% of our RESCULA product sales for the three months ended March 31, 2013.

Co-promotion Revenue

Co-promotion revenues relate to reimbursements of co-promotion costs based upon a rate per detail and reimbursements of the costs of miscellaneous marketing activities.

Contract and Collaboration Revenue

Contract revenue relates to development and consulting activities and is accounted for under the time-based model.

The Company considers its participation in the joint committees under the collaboration and license agreements as separate deliverables under the contracts and recognizes the fair value of such participation as collaboration revenue over the period of the participation per the terms of the contracts.

The Company has determined that it is acting as a principal under both the Takeda Agreement and Abbott Agreement and, as such, records revenue on a gross basis in the Condensed Consolidated Statements of Comprehensive Income (Loss).

Cost of Goods Sold

Cost of goods sold relates to sales and distribution of the Company’s products sold by the Company.

Certain Risks, Concentrations and Uncertainties

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash and cash equivalents, restricted cash, investments and receivables. The Company places its cash, cash equivalents and restricted cash with highly rated financial institutions and invests its excess cash in highly rated investments. As of March 31, 2013 and December 31, 2012, approximately $15.7 million, or 16.4%, and $15.6 million, or 16.7%, respectively, of the Company’s cash, cash equivalents, restricted cash and investments were issued or insured by the federal government or government agencies. The Company has not experienced any losses on these accounts related to amounts in excess of insured limits.

The Company’s products and product candidates under development require approval from the FDA or other international regulatory agencies prior to commercial sales. For those product candidates or indications that have not yet been approved by the FDA or international regulatory agencies, there can be no assurance the products will receive the necessary approval. If the Company is denied approval or approval is delayed, it may have a material adverse impact on the Company.

The Company’s products, AMITIZA and RESCULA, compete in a rapidly changing, highly competitive market, which is characterized by advances in scientific discovery, changes in customer requirements, evolving regulatory requirements and developing industry standards. Any failure by the Company to anticipate or to respond adequately or timely to scientific developments in its industry, changes in customer requirements or changes in regulatory requirements or industry standards, or any significant delays in the development or introduction of products could have a material adverse effect on the Company’s business, operating results and future cash flows.

The Company’s working capital requirements will depend on many factors, including the successful sales of AMITIZA and RESCULA, research and development efforts to develop new products or indications, payments received under contractual agreements with other parties, the status of competitive products and market acceptance of the Company’s new products by physicians and patients. The Company plans to continue financing operations with its existing cash and investments as well as with product royalty revenue and cash received from milestones and other revenue related to its joint collaboration, license and supply agreements.

Revenues from one unrelated party, Takeda, accounted for 86.8% and 98.3%, of the Company’s total revenues for the three months ended March 31, 2013 and 2012, respectively. Accounts receivable, unbilled accounts receivable and product royalties receivable from Takeda accounted for 97.2% and 98.0% of the Company’s total accounts receivable, unbilled accounts receivable and product royalties receivable at March 31, 2013 and December 31, 2012, respectively. Revenues from another unrelated party, Abbott, accounted for 13.1% and 1.0% of the Company’s total revenues for the three months ended March 31, 2013 and 2012, respectively. The Company depends significantly upon the collaborations with Takeda and Abbott and its activities may be impacted if these relationships are disrupted.

The Company has an exclusive supply arrangement with R-Tech to provide it with commercial and clinical supplies of its product and product candidates. R-Tech also provides certain preclinical and other research and development services. Any difficulties or delays in performing the services under these arrangements may cause the Company to lose revenues, delay research and development activities or otherwise disrupt the Company’s operations (Note 8).

3. Net Income (Loss) per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the sum of the weighted average class A common shares outstanding. Diluted net income per share is computed by dividing net income by the weighted average common shares and potential dilutive common shares outstanding. Diluted net loss per share, when applicable, is computed by dividing net loss by the weighted average common shares outstanding without the impact of potential dilutive common shares outstanding because they would have an anti-dilutive impact on diluted net loss per share.

The computation of net income (loss) per share for the three months ended March 31, 2013 and 2012 is shown below:

The Company performs fair value measurements in accordance with the FASB’s guidance for fair value measurements and disclosures, which defines fair value as the exchange price that would be received for selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A fair value hierarchy is established which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company classifies its investments into the following categories based on the three levels of inputs used to measure fair value:

10

SUCAMPO PHARMACEUTICALS, INC.

Notes to Condensed Consolidated Financial Statements (Unaudited) – (Continued)

Level 1: quoted prices in active markets for identical assets or liabilities;

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

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

The Company’s assets measured at fair value on a recurring basis, including cash equivalents, which are subject to the fair value disclosure requirements, are as follows:

	Fair Value Measurements at Reporting Date Using

If quoted prices in active markets for identical assets and liabilities are not available to determine fair value, then the Company uses quoted prices for similar assets and liabilities or inputs other than the quoted prices that are observable, either directly or indirectly. This pricing methodology applies to the Company’s Level 2 investments.

In April 2009, the Company entered into an agreement with R-Tech, or the 2009 R-Tech Agreement, to acquire all patents and other intellectual property rights related to RESCULA for its FDA approved indication and any new indications for unoprostone isopropyl in the United States and Canada. The Company has begun commercializing RESCULA (unoprostone isopropyl ophthalmic solution) 0.15% for the lowering of IOP in patients with open-angle glaucoma or ocular hypertension.

Under the terms of the 2009 R-Tech Agreement, the Company made an upfront and development payments of $3.5 million and may be required to pay up to $5.0 million in additional milestone payments to R-Tech based on the achievement of specified development and commercialization goals. The Company allocated the acquisition cost between an intangible asset of $3.4 million and a non-current prepaid inventory of $85,000 as of March 31, 2013 which is reflected in other non-current assets in the accompanying Condensed Consolidated Balance Sheets. Upon the February 2013 RESCULA re-launch, a $500,000 milestone payment was paid in May 2013.The cost is amortized over the 10-year life of the 2009 R-Tech Agreement, which the Company believes approximates the useful life of the underlying rights and data. Amortization expense was approximately $85,000 for the three months ended March 31, 2013 and March 31, 2012, respectively. The annual amortization expense will be approximately $341,000 through April 2019.

On March 22, 2011, the Company entered into a license agreement with R-Tech for unoprostone isopropyl, or the 2011 R-Tech Agreement, expanding the Company’s development and commercialization rights as well as its territories beyond their previously agreed territory of the United States and Canada to the rest of the world, with the exception of Japan, Korea, Taiwan and the People’s Republic of China. The Company is now evaluating opportunities to obtain an appropriate label in the European Union and other European countries, and the timing of seeking reauthorization in those countries to commercialize unoprostone isopropyl.

The Company has made payments to R-Tech of $6.0 million, which is reflected in other non-current assets in the accompanying Condensed Consolidated Balance Sheets, and may be required to pay up to $100.0 million in additional milestone payments to R-Tech based on the achievement of specified development and commercialization goals. The Company will be responsible for all development, regulatory, and commercialization activities. The Company is amortizing the $6.0 million over the 10-year life of the license agreement, which the Company believes approximates the useful life of the underlying rights and data. Amortization expense was approximately $153,000 for the three months ended March 31, 2013 and 2012, respectively. The annual amortization expense will be approximately $613,000 through March 2021.

Research and Development Costs

The Company routinely enters into agreements with third-party contract research organizations to oversee clinical research and development studies provided on an outsourced basis and assist in other research and development activities. The Company generally is not contractually obligated to pay the third party if the service or reports are not provided. Total future estimated costs through 2015 under these agreements as of March 31, 2013 were approximately $10.4 million.

Any contingent liability under the agreement with Numab in the event that Numab defaults under its loan with Zurcher Kantonalbank up to a maximum potential amount of $2.3 million. As of March 31, 2013, the potential amount of payments in the event of Numab’s default was $2.3 million.

We had an outstanding purchase order commitment of approximately $817,000 with R-Tech (see Note 8 below).

Notes to Condensed Consolidated Financial Statements (Unaudited) – (Continued)

The Company recognized approximately $163,000 and $105,000 of revenue relating to its agreements with R-Tech for each of the three months ended March 31, 2013 and 2012, respectively, which was recorded as contract and collaboration revenue in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).

Beginning October 2012, R-Tech is relocating its manufacturing facility for unoprostone isopropyl and will not be able to manufacture and supply unoprostone isopropyl for up to 18 months. R-Tech has designated another facility in Japan but such facility will need to be inspected by the FDA in 2013 before it can manufacture unoprostone isopropyl. In order to mitigate this risk, the Company placed an order of $5.3 million to cover this supply period based on Company forecasts for the launch of RESCULA in the United States, R-Tech delivered $4.5 million of that order to the Company in the first quarter of 2013.

Numab AG

In September 2011, the Company entered into a Loan Guarantee and Development Agreement, or the Numab Agreement, with Numab. Numab is considered a related party as a result of an ownership interest by one of our executive officers. Under the terms of the Numab Agreement the Company will provide Numab with up to CHF 5.0 million as collateral and will serve as guarantor for a loan to Numab from a third party. Following payment of the first success fee during the quarter this amount was reduced to CHF 2.2 million, approximately $2.3 million as of the closing date, The Company may name up to three further targets against which Numab will use their proprietary technology to discover high-affinity antibodies and to develop these to an investigational new drug ready stage. Numab is eligible for full time equivalent based payments and discovery success dependent fees. Any success dependent fees will result in a corresponding reduction in the amount of the available guarantee.

As of March 31, 2013, the collateral of CHF 2.2 million has been deposited by the Company and Numab has utilized CHF 2.0 million of its CHF 2.0 million loan During 2012 we considered it probable the success criteria for the first target would be met and made full provision for the success fee. This fee was paid during the first quarter of 2013. The Company has decided to no longer pursue the further development of the target. Numab and the Company are in discussions in light of this decision.

SUCAMPO PHARMACEUTICALS, INC.

Notes to Condensed Consolidated Financial Statements (Unaudited) – (Continued)

The Company granted 510,000 stock options with an exercise price of $5.85 per share to non-employees in August 2005 under the Company’s 2001 Incentive Plan. As of March 31, 2013 and December 31, 2012, 450,000 of these options were outstanding and exercisable. These non-employee stock options vested immediately and have a weighted average exercise price per share of $5.85 and $5.85, respectively, and remaining contractual life of 2.09 and 2.33 years, respectively, as of March 31, 2013 and December 31, 2012.

Employee Stock Purchase Plan

Under the Company’s 2006 Employee Stock Purchase Plan, or ESPP, a total of 784 and 938 shares of class A common stock were purchased during the three months ended March 31, 2013 and 2012, respectively. The ESPP is non-compensatory and is intended to qualify as an Employee Stock Purchase Plan as defined in Section 423 of the Internal Revenue Code of 1986, as amended, and in accordance with GAAP guidance that requires estimates in the fair value of share-based payment awards on the date of the grant using an option-pricing model and recognizing the expense over the required service periods in the accompanying Condensed Consolidated Statement of Comprehensive Income (Loss). The Company received $4,871 and $6,639 upon purchase of shares under the ESPP for the three months ended March 31, 2013 and 2012, respectively.

12. Income Taxes

For the three months ended March 31, 2013 and 2012, the Company recorded a tax provision of $1.1 million and $2.3 million, respectively. The tax provision for the three months ended March 31, 2013 and 2012 primarily pertained to pre-tax profits generated by the Company’s U.S and Japanese subsidiaries.

The Company has estimated its annual effective tax rate for the full fiscal year 2013 and 2012 and applied that rate to its income before income taxes in determining its income tax provision for the interim periods. Non-recurring and discrete items that impact tax expense are recorded in the period incurred.

Uncertain Tax Positions

The Company applies the relevant guidance for uncertainty in income taxes that requires the application of a more likely than not threshold to the recognition and derecognition of uncertain tax positions.

The Company had an outstanding non-current income tax liability of approximately $1.0 million, including interest, for uncertain tax positions as of March 31, 2013. The amount represented the aggregate tax effect of differences between tax return positions and the amounts otherwise recognized in the Company’s Condensed Consolidated Financial Statements. As of March 31, 2013, $549,000 and $475,000 is reflected as other current liabilities and other liabilities, respectively in the accompanying Condensed Consolidated Balance Sheets. The liability for uncertain tax positions as of March 31, 2013 mainly pertained to the Company’s interpretation of nexus in certain states related to revenue sourcing for state income tax purposes. During the three months ended March 31, 2013, the liability for income taxes has decreased approximately $108,000. This decrease in the liability is primarily related to the filing of voluntary disclosures and tax returns with various state tax authorities during the quarter offset by an increase related to current year activity in the United States.

The Company recognizes accrued interest and penalties related to uncertain tax positions as a component of the income tax provision. Other than the expected settlement of state tax liabilities, no additional uncertain tax positions have been identified for which it is reasonably possible that the total amount of liability for unrecognized tax benefits will significantly increase or decrease within 12 months, except for recurring accruals on existing uncertain tax positions. In addition, future changes in the unrecognized tax benefits would have an effect on the effective rate when recognized.

13. Segment Reporting

The Company has determined that it has three reportable segments based on the Company’s method of internal reporting, which disaggregates business by geographic location. These segments are the Americas, Europe and Asia. The Company evaluates the performance of these segments based on income (loss) from operations, as well as other factors, that depend on the development status of these geographies. Such measures include the progress of its research and development activities, collaboration and licensing efforts, commercialization activities, product sales and other factors. The reportable segments have historically derived their revenue from joint collaboration and strategic alliance agreements. Transactions between the segments consist primarily of loans and the provision of research and development services. Following is a summary of financial information by reportable geographic segment:

This Quarterly Report on Form 10-Q contains forward-looking statements regarding Sucampo Pharmaceuticals, Inc. (the “Company,” “we,” “us,” or “our”) and our business, financial condition, results of operations and prospects within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements include those that express plans, anticipation, intent, contingency, goals, targets or future development and/or otherwise are not statements of historical fact. These forward-looking statements are based on our current expectations and projections about future events and they are subject to risks and uncertainties known and unknown that could cause actual results and developments to differ materially from those expressed or implied in such statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified below, and those discussed in the section titled “Risk Factors” included elsewhere in this Quarterly Report Form 10-Q and in our other SEC filings, including our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, which we filed with the SEC on March 18, 2013. You should also read the following discussion and analysis of our financial condition and results of operations in conjunction with our Consolidated Financial Statements as of and for the year ended December 31, 2012 included in our Annual Report on Form 10-K.

Overview

We are a global pharmaceutical company focused on innovative research, discovery, development and commercialization of proprietary drugs based on prostones and other novel drug technologies. The therapeutic potential of prostones was first discovered by our cofounder, Dr. Ryuji Ueno, and under his leadership we have pioneered the field of prostones. Prostones are naturally occurring fatty acid metabolites. Originally thought to be biologically inert, prostones have emerged as a promising compound class with unique physiological activities which can be targeted for the treatment of unmet or underserved medical needs.

We are focused on developing and/or commercializing prostone-based drugs to treat gastrointestinal, ophthalmic, neurologic, and oncology-based inflammatory disorders, and are also considering other potential therapeutic applications of our drug technologies.

We currently generate revenue mainly from product royalties, development milestone payments, clinical development activities and product sales. We expect to continue to incur significant expenses for the next several years as we continue our research and development activities, seek additional regulatory approvals and additional indications for AMITIZA^® (lubiprostone), RESCULA^® (unoprostone isopropyl) and other compounds, and commercialize our approved products (as discussed below) on a global basis.

To date, two prostone products have received marketing approval, AMITIZA and RESCULA. A third prostone, cobiprostone, or SPI-8811, is in phase 1 clinical development for the target indication of prevention of oral mucositis, or OM. Two additional prostones, SPI-017 and SPI-3608, have also been developed for human testing for the indication of management of pain caused by spinal stenosis, and SPI-017 is currently in a phase 2A trial that is expected to conclude by the fourth quarter of 2013.

Our operations are conducted through subsidiaries based in Japan, the United States, Switzerland, the United Kingdom and Luxembourg. Our reportable geographic segments are Asia, the Americas and Europe and we evaluate the performance of these segments based primarily on income (loss) from operations, as well as other factors that depend on the growth of these subsidiaries. Such measures include the progress of research and development activities, collaboration and licensing efforts, commercialization activities and other factors.

Drs. Ryuji Ueno and Sachiko Kuno are our controlling stockholders and are married to each other. Dr. Ueno is our Chief Executive Officer and Chairman of the Board of Directors. Dr. Kuno was a member of our Board of Directors and our executive advisor on international business development through September 30, 2012. Drs. Ueno and Kuno, together, directly or indirectly, own a majority of the stock of R-Tech Ueno, Ltd., or R-Tech, a pharmaceutical research, development and manufacturing company in Japan. R-Tech is responsible for the manufacture and supply of all of our prostone products for commercial use or clinical development.

Our Prostone Products, Approved and in the Clinic

We are developing prostone compounds for the treatment of a broad range of diseases. The most advanced of these programs are:

AMITIZA in the United States and Canada

20

In April 2013, we received approval for a supplemental new drug application, or sNDA, for AMITIZA at dosage strength of 24 micrograms twice daily as the first and only oral medication for the treatment of OIC in adult patients with chronic, non-cancer pain. Upon the first commercial sale of AMITIZA for OIC, we will recognize a $10.0 million milestone payment from Takeda, which we expect to receive in the second quarter.

AMITIZA in Japan

In June 2012, we received approval from the Ministry of Health, Labour and Welfare, or MHLW, in Japan, for the use of AMITIZA for chronic constipation, or CC, excluding constipation caused by organic diseases. In November 2012, Abbott began marketing AMITIZA in Japan for CC. AMITIZA is Japan’s only prescription medicine for CC.

AMITIZA in other territories

In the United Kingdom, we are currently working to achieve National Institute for Care Excellence, or NICE endorsement and launch AMITIZA to treat CIC in the United Kingdom in 2013. In Switzerland, we began active marketing of AMITIZA in the first quarter of 2013.

In the first quarter of 2013, we commenced the MRP approval process in other European Union countries for CIC. In the first quarter of 2013, we also filed for an OIC indication in the United Kingdom and Switzerland. If we receive approval in the United Kingdom, we will seek approval in other countries of the European Union following an MRP for OIC.

RESCULA

Under our 2009 and 2011 agreements with R-Tech, we hold the exclusive rights to commercialize and develop RESCULA worldwide except for Japan, Korea, Taiwan and the People’s Republic of China, or R-Tech Territory, for its approved indication and all new ophthalmic indications developed by us. We are also evaluating the opportunities in the European Union and other European countriesto commercialize unoprostone isopropyl there. We also seek to develop new formulations using third party proprietary drug delivery technologies. We are exploring research programs with those third parties.

An sNDA for RESCULA (unoprostone isopropyl ophthalmic solution) 0.15% for the lowering of intraocular pressure, or IOP, in patients with open-angle glaucoma or ocular hypertension was approved by the FDA in December 2012 and we began commercializing the product in February 2013. In April 2013, we paid a $500,000 milestone payment to R-Tech upon the February 2013 RESCULA re-launch. According to the approved product labeling, RESCULA may be used as a first-line agent or concomitantly with other topical ophthalmic drug products to lower intraocular pressure. RESCULA is a BK channel activator, acting via an entirely different mechanism of action as compared to any other IOP lowering agent on the market.

In February 2013, we announced that the Japan Science and Technology Agency, or JST, adopted unoprostone isopropyl ophthalmic solution 0.15% in the Adaptable and Seamless Technology Transfer Program. As part of this program, R-Tech, our development partner, has signed an agreement for unoprostone isopropyl with the JST in which the Japanese government shall provide the majority of funding for phase 3 clinical development costs for unoprostone isopropyl for retinitis pigmentosa, or RP. We are co-developing unoprostone isopropyl with R-Tech and may file for FDA and European Medicines Agency approval for the treatment of RP in the future assuming successful clinical studies.

Product Pipeline

The table below summarizes the development status of lubiprostone, unoprostone isopropyl and several other prostone-based product candidates. We currently hold all of the commercialization rights to the prostone compounds in our product pipeline, other than for commercialization of AMITIZA in the United States, Canada and Japan, which is covered by our collaboration and license agreements with Takeda and Abbott, and for RESCULA, for which we hold all rights except in the R-Tech Territory. Commercialization may be after successful completion of clinical studies.

The changes in general and administrative expense were primarily due to continued investment in corporate marketing and branding and staff to support business growth, partially offset by lower legal, consulting, and other professional expenses as a result of the conclusion of certain legal matters in 2012.

Selling and Marketing Expenses

The following summarizes our selling and marketing expenses for the three months ended March 31, 2013 and 2012:

	Three Months Ended
	March 31,

Selling and marketing expenses were $5.4 million for the three months ended March 31, 2013, compared to $4.1 million for the three months ended March 31, 2012, an increase of $1.3 million or 31.8%. The increase in selling and marketing expenses relates primarily to commercialization and launch costs for RESCULA.

Non-Operating Income and Expense

The following table summarizes our non-operating income and expense for the three months ended March 31, 2013 and 2012:

	Three Months Ended
	March 31,

The majority of the decrease relates to higher foreign exchange gains in the prior year period that are unrealized and non-cash and that relate to amounts held within subsidiaries.

Income Taxes

We recorded a tax provision of $1.1 million and $2.3 million for three months ended March 31, 2013 and 2012, respectively. The tax provision for the three months ended March 31, 2013 primarily related to pre-tax income generated by our United States and Japanese subsidiaries.

Reportable Geographic Segments

24

We have determined that we have three reportable segments based on our method of internal reporting, which disaggregates business by geographic location. These segments are the Americas, Europe and Asia. We evaluate the performance of these segments based primarily on income (loss) from operations, as well as other factors, including the progress of research and development activities. The financial results in these three segments based on geographic locations for the three months ended March 31, 2013 are summarized in the table below.

The financial results of our segments reflect their varying stages of development. Our Americas segment recorded income before taxes of $2.9 million for the three months ended March 31, 2013 compared to income before taxes of $3.4 million for three months ended March 31, 2012.

Our segment in Europe recorded a loss before taxes of $4.2 million for the three months ended March 31, 2013 compared to loss before taxes of $2.8 million for the three months ended March 31, 2012.

Our segment in Asia recorded a loss before taxes of $786,000 for the three months ended March 31, 2013 compared to a loss before taxes of $237,000 during the three months ended March 31, 2012.

Financial Condition, Liquidity and Capital Resources

Financial Condition

Sources of Liquidity

We finance our operations principally from cash generated from revenues, cash and cash equivalents on hand and to a lesser extent from the sale of securities through the exercise of stock options.

As of March 31, 2013 and December 31, 2012, our restricted cash consisted primarily of the collateral pledged to support a loan agreement with The Bank of Tokyo-Mitsubishi UFJ, Ltd., a loan agreement with Mizuho Bank, Ltd., Numab’s loan with Zurcher Kantonalbank and operating leases with certain financial institutions.

As of March 31, 2013, our short-term investments consisted of certificates of deposits, corporate bonds, commercial paper and variable rate demand notes that have short-term maturities of one year or less.

Net cash used in investing activities was $7.9 million for the three months ended March 31, 2013. This primarily reflected an increase in restricted cash associated with collateral pledged to support loan agreements, partially offset by our proceeds from the sales and maturities of investments.

Net provided by in financing activities of $10.3 million for the three months ended March 31, 2013 primarily reflected proceeds from a loan agreement with Mizuho Bank, Ltd., partially offset by purchases under the stock repurchase program (as discussed below under “Funding Requirements.

The effect of exchange rates on the cash balances of currencies held in foreign denominations for the three months ended March 31, 2012 was a decrease of $2.3 million.

Off-Balance Sheet Arrangements

26

As of March 31, 2013, we did not have any off-balance sheet arrangements, as such term is defined in Item 303(a)(4) of Regulation S-K under the Securities Act of 1933, as amended.

Funding Requirements

On December 11, 2008, we announced a stock repurchase program pursuant to which we are authorized to purchase up to $10.0 million of our class A common stock from time to time in open market transactions. On September 8, 2011, we announced that our Board approved the repurchase of up to an aggregate of $2.0 million of its Class A common stock out of the $10.0 million authorized. On November 2, 2012, our Board authorized the increase of such amount of repurchase to up to an aggregate of $5.0 million. During the first three months of 2013, we repurchased 67,762 shares of our class A common stock under this program at a cost of $0.3 million.

We may need substantial amounts of capital to continue growing our business. We may require this capital, among other things, to fund:

· our share of the on-going development program of AMITIZA in the United States;

· the launch and development of RESCULA in the United States;

· development, regulatory and marketing efforts in Europe and Asia for lubiprostone;

· development and regulatory activities for unoprostone isopropyl in the United States and Canada and other countries except Japan, Korea, Taiwan and The People’s Republic of China;

· development, marketing and manufacturing activities at SAG;

· activities to resolve our on-going legal matters;

· the costs involved in obtaining and maintaining proprietary protection for our products, technology and know-how, including litigation costs and the results of such litigation;

· research and development activities for other prostone compounds, including cobiprostone, SPI-3608 and SPI-017;

· other business development activities, including partnerships, alliances and investments in or acquisitions of other businesses, products and technologies;

· the expansion of our commercialization activities including the purchase of inventory;

· the continuing purchase of shares of our class A common stock up to $5.0 million pursuant to the recently implemented repurchase program, and if we elect to do so, increasing the repurchase program up to $10.0 million previously approved by our Board of Directors; and

· the satisfaction of the conditions of our loan note obligations.

The timing of these funding requirements is difficult to predict due to many factors, including the outcomes of our preclinical and clinical research and development programs and when those outcomes are determined, the timing of obtaining regulatory approvals and the presence and status of competing products. Our capital needs may exceed the capital available from our future operations, collaborative and licensing arrangements and existing liquid assets. Our future capital requirements and liquidity will depend on many factors, including, but not limited to:

· the cost and time involved to pursue our research and development programs;

· our ability to establish collaborative arrangements and to enter into licensing agreements and contractual arrangements with others; and

· any future change in our business strategy.

To the extent that our capital resources may be insufficient to meet our future capital requirements, we may need to finance our future cash needs through public or private equity offerings, debt financings or corporate collaboration and licensing arrangements. At March 31, 2013, we have sufficient liquidity for the next 12 months.

Additional equity or debt financing, grants or corporate collaboration and licensing arrangements may not be available on acceptable terms, if at all. If adequate funds are not available, we may be required to delay, reduce the scope of or eliminate our research and development programs, reduce our planned commercialization efforts or obtain funds through arrangements with collaborators or others that may require us to relinquish rights to certain product candidates that we might otherwise seek to develop or commercialize independently. In addition, any future equity funding would dilute the ownership of our stockholders.

Effects of Foreign Currency

27

We currently incur a portion of our operating expenses in Switzerland, Japan and the United Kingdom. The reporting currency for our Condensed Consolidated Financial Statements is United States dollars. As such, the results of our operations could be adversely affected by changes in exchange rates either due to transaction losses, which are recognized in the statement of operations, or translation losses, which are recognized in comprehensive income. We currently do not hedge foreign exchange rate exposure via derivative instruments.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our market risks during the three months ended March 31, 2013 have not materially changed from those discussed in Part II, Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2012, which was filed with the SEC on March 18, 2013.

Foreign Exchange Rate Risk

We are subject to foreign exchange risk for revenues and expenses denominated in foreign currencies. Foreign currency risk arises from the fluctuation of foreign exchange rates and the degree of volatility of these rates relative to the United States dollar.

Interest Rate Risk

Our exposure to market risks associated with changes in interest rates relates primarily to the increase or decrease in the amount of interest income earned on our investment portfolio. We ensure the safety and preservation of invested funds by attempting to limit default risk, market risk and reinvestment risk. We attempt to mitigate default risk by investing in investment grade securities. A hypothetical one percentage point decline in interest rates would not have materially affected the fair value of our interest-sensitive financial instruments as of March 31, 2013.

We do not use derivative financial instruments for trading or speculative purposes. However, we regularly invest excess cash in overnight repurchase agreements that are subject to changes in short-term interest rates. We believe that the market risk arising from holding these financial instruments is minimal.

Credit Risk

Our exposure to credit risk consists of cash and cash equivalents, restricted cash, investments and receivables. We place our cash, cash equivalents and restricted cash with what we believe to be highly rated financial institutions and invest the excess cash in highly rated investments. As of March 31, 2013 and December 31, 2012, approximately 16.4% and 16.7%, respectively, of our cash, cash equivalents, restricted cash and investments are issued or insured by the federal government or government agencies. We have not experienced any losses on these accounts related to amounts in excess of insured limits.

Item 4. Controls and Procedures

a) Evaluation of Disclosure Controls and Procedures

Our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of the design and operation 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, or the Exchange Act, as of March 31, 2013. In designing and evaluating such controls, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Based upon the evaluation we carried out, our Chief Executive Officer and Chief Financial Officer have concluded that, as of March 31, 2013, our disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified under the applicable rules and forms of the SEC, and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

b) Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2013 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Part II — OTHER INFORMATION

Item 1. Legal Proceedings.

On January 2, 2013, we received a first Notice Letter and on January 25, 2013, we received a second Notice Letter from Anchen and Par regarding their filing of an Abbreviated New Drug Application with the FDA to market a generic version of AMITIZA oral capsules, 8 mcg and 24 mcg. On February 8 2013, we announced that we, along with R-Tech and Takeda, filed a patent infringement lawsuit in the United States District Court for the District of Delaware against Anchen and Par. The lawsuit claims infringement of six patents that are listed in the FDA’s Orange Book and that are scheduled to expire between 2020 and 2027. The patent infringement lawsuit is beginning the discovery phase.

Item 1A. Risk Factors.

Our business is subject to certain risks and events that, if they occur, could adversely affect our financial condition and results of operations and the trading price of our common stock. For a discussion of these risks, please refer to the “Risk Factors” section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, filed by us with the SEC on March 18, 2013. There have not been any material changes from the risk factors as previously disclosed in our Form 10-K filed on March 18, 2013.

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

(a) None.

(b) Not applicable.

* On December 11, 2008, we announced a stock repurchase program pursuant to which we are authorized to purchase up to $10.0 million of our class A common stock from time to time in open market transactions. On September 8, 2011, we announced that our Board of Directors approved the repurchase of up to an aggregate of $2,000,000 of our Class A common stock out of the $10.0 million authorized. On November 2, 2012, our Board of Directors authorized the increase of such amount of repurchase to up to an aggregate of $5.0 million. The stock repurchase program is expected to continue through the third quarter of 2013 unless extended or shortened.

Net Income (Loss) per Share

Net Income (Loss) per Share

3.Net Income (Loss) per Share

Basic net income (loss)per share is computed by dividing net income (loss) by the sum of the weighted average class A common shares outstanding. Diluted net income per share is computed by dividing net income by the weighted average common shares and potential dilutive common shares outstanding. Diluted net loss per share, when applicable, is computed by dividing net loss by the weighted average common shares outstanding without the impact of potential dilutive common shares outstanding because they would have an anti-dilutive impact on diluted net loss per share.

The computation of net income (loss) per share for the three months ended March 31, 2013 and 2012 is shown below:

Summary Of Significant Accounting Policies [Abstract]

Summary Of Significant Accounting Policies

2.Summary of Significant Accounting Policies

Cash and Cash Equivalents

For the purpose of the Condensed Consolidated Balance Sheets and Statements of Cash Flows, cash equivalents include all highly liquid investments with a maturity of 90 days or less at the time of purchase.

Restricted Cash

Restricted cash consists of approximately $28.4 million and $18.9million at March 31, 2013 and December 31, 2012, respectively.  Restricted cash represents cash required to be deposited with certain financial institutions in connection with a loan agreement with The Bank of Tokyo-Mitsubishi UFJ, Ltd., a loan agreement with Mizuho Bank, Ltd., Numab’s loan with Zurcher Kantonalbank and operating leases.

Current and Non-current Investments

Current and non-current investments consist primarily of United States government agency securities, certificates of deposits and variable rate demand notes. The Company classifies its investments into current and non-current based on their maturities and management’s reasonable expectation to realize these investments in cash. The Company classifies all of its investments as available for sale securities and reports unrealized gains or losses, net of related tax effects,in other comprehensive income.

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, which include cash and cash equivalents, restricted cash, current and non-current investments, receivables, accounts payable and accrued expenses, approximate their fair values based on their short maturities, independent valuations or internal assessments.The carrying amount of the notes payable at March 31, 2013 was less than the estimated fair value and at December 31, 2012 approximated its fair value.The Company’s debt is subject to the fair value disclosure requirements as discussed in Note 4 below, is considered a Level 2 security.

Accounts Receivable and Unbilled Accounts Receivable

Accounts receivable represent mainly amounts due under the Takeda and the Abbott Agreements. Unbilled accounts receivable represent the research and development expenses that are reimbursable by Takeda but have not been billed to Takeda as of the balance sheet date. The Company recorded an allowance for doubtful accounts at March 31, 2013 and December 31, 2012 of approximately $354,000 and $280,000, respectively, related to certain disputed Takeda invoices.

Product Royalties Receivable

Product royalties receivable represent amounts due from Takeda for the Company’s royalties on sales of AMITIZA, which are based on reports obtained directly from Takeda.

Revenue Recognition

The Company’s revenuesare derived primarily from collaboration and license agreements and include upfront payments, development milestone payments, reimbursements of development and co-promotion costs, product sales and product royalties.

Research and Development Revenue

The Company evaluated the multiple deliverables within the collaboration and license agreements in accordance with the guidance of multiple deliverables to determine whether the delivered elements that are the obligation of the Company have value to other parties to the agreement on a stand-alone basis and whether objective reliable evidence of fair value of the undelivered items exists. Deliverables that meet these criteria are considered a separate unit of accounting. Deliverables that do not meet these criteria are combined and accounted for as a single unit of accounting. The appropriate recognition of revenue is then applied to each separate unit of accounting. The Company’s deliverables under the Takeda Agreement and the Abbott Agreement, including the related rights and obligations, contractual cash flows and performance periods, are more fully described in Note 10 below.

Product Royalty Revenue

Royalty revenues are based on net sales of licensed products and are recorded on the accrual basis when earned in accordance with contractual terms when third-party results are reliably measurable, collectability is reasonably assured and all other revenue recognition criteria are met.

Product Sales Revenue

AMITIZA product sales consist of AMITIZA sales to Abbott in Japan. Revenue from AMITIZA product sales is recognized when persuasive evidence of an arrangement exists, delivery has occurred and title to product and associated risk of loss have passed to the customer, the price is fixed or determinable, and collection from the customer is reasonably assured. The Company did not record sales deductions and returns for sales of AMITIZA to Abbott due to the absence of discounts and rebates and no right of return under the contract with Abbott.

RESCULA product sales consist of RESCULA sales in the United States. The Company recognizes revenue from RESCULA product sales less deductions for estimated sales discounts and sales returns. Revenue from product sales of RESCULA is recognized when persuasive evidence of an arrangement exists, title passes, the price is fixed or determinable, and collectability is reasonably assured. The Company accounts for rebates to certain governmental agencies as a reduction of product sales. The Company allows customers to return product within a specified time period prior to and subsequent to the product’s labeled expiration date. As a result, the Company estimates an accrual for product returns, which is recorded as a reduction of product sales. Given the Company’s limited history of selling RESCULA and the return period, the Company cannot reasonably estimate product returns from the wholesale distribution channel. Therefore the Company is deferring the recognition of revenue until there is confirmation of pull through sales to pharmacies or other end user customers. We will continue to defer recognition until the point at which we have obtained sufficient sales history to reasonably estimate returns from the wholesalers. Our three largest wholesale customers accounted for 89.9% of our RESCULA product sales for the three months ended March 31, 2013.

Co-promotion Revenue

Co-promotion revenues relate to reimbursements of co-promotion costs based upon a rate per detail and reimbursements of the costs of miscellaneous marketing activities.

Contract and Collaboration Revenue

Contract revenue relates to development and consulting activities and is accounted for under the time-based model.

The Company considers its participation in the joint committees under the collaboration and license agreements as separate deliverables under the contracts and recognizes the fair value of such participation as collaboration revenue over the period of the participation per the terms of the contracts.

The Company has determined that it is acting as a principal under both the Takeda Agreement and Abbott Agreement and, as such, records revenue on a gross basis in the Condensed Consolidated Statements of Comprehensive Income (Loss).

Cost of Goods Sold

Cost of goods sold relates to sales and distribution of the Company’s products sold by the Company.

Certain Risks, Concentrations and Uncertainties

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash and cash equivalents, restricted cash, investments and receivables. The Company places its cash, cash equivalents and restricted cash with highly rated financial institutions and invests its excess cash in highly rated investments.  As of March 31, 2013 and December 31, 2012, approximately $15.7 million, or 16.4%, and $15.6 million, or 16.7%, respectively, of the Company’s cash, cash equivalents, restricted cash and investments were issued or insured by the federal government or government agencies.The Company has not experienced any losses on these accounts related to amounts in excess of insured limits.

The Company’s products and product candidates under development require approval from the FDA or other international regulatory agencies prior to commercial sales. For those product candidates or indications that have not yet been approved by the FDA or international regulatory agencies, there can be no assurance the products will receive the necessary approval. If the Company is denied approval or approval is delayed, it may have a material adverse impact on the Company.

The Company’s products, AMITIZA and RESCULA, compete in a rapidly changing, highly competitive market, which is characterized by advances in scientific discovery, changes in customer requirements, evolving regulatory requirements and developing industry standards. Any failure by the Company to anticipate or to respond adequately or timely to scientific developments in its industry, changes in customer requirements or changes in regulatory requirements or industry standards, or any significant delays in the development or introduction of products could have a material adverse effect on the Company’s business, operating results and future cash flows.

The Company’s expected activities may necessitate significant uses of working capital. The Company’s working capital requirements will depend on many factors, including the successful sales of AMITIZA and RESCULA, research and development efforts to develop new products or indications, payments received under contractual agreements with other parties, the status of competitive products and market acceptance of the Company’s new products by physicians and patients. The Company plans to continue financing operations with its existing cash and investments as well as with product royalty revenue and cash received from milestones and other revenue related to its joint collaboration, license and supply agreements.

Revenues from one unrelated party, Takeda, accounted for 86.8% and98.3%,  of the Company’s total revenues for the three months ended March 31, 2013 and 2012, respectively. Accounts receivable, unbilled accounts receivable and product royalties receivable from Takeda accounted for97.2%  and 98.0%  of the Company’s total accounts receivable, unbilled accounts receivable and product royalties receivable at March 31, 2013 and December 31, 2012, respectively.  Revenues from another unrelated party, Abbott, accounted for13.1% and 1.0%  of the Company’s total revenues for the three months ended March 31, 2013 and 2012, respectively.The Company depends significantly upon the collaborations with Takeda and Abbott and its activities may be impacted if these relationships are disrupted.

The Company has an exclusive supply arrangement with R-Tech to provide it with commercial and clinical supplies of its product and product candidates. R-Tech also provides certain preclinical and other research and development services. Any difficulties or delays in performing the services under these arrangements may cause the Company to lose revenues, delay research and development activities or otherwise disrupt the Company’s operations (Note 8).

1.Business Organization and Basis of Presentation

Description of the Business

Sucampo Pharmaceuticals, Inc., or the Company, is  a global pharmaceutical company focused on innovative research, discovery, development and commercialization of proprietary drugs based on prostones and other novel drug technologies.The therapeutic potential of prostones was first discovered by the Company’s co-founder, Dr. Ryuji Ueno, and under his leadership the Company has pioneered the field of prostones. Prostones are naturally occurring fatty acid metabolites. Originally thought to be biologically inert, prostones have emerged as a promising compound class with unique physiological activities which can be targeted for the treatment of unmet or underserved medical needs.

Prostones act locally to restore normal function in cells and tissues.They are rapidly metabolized to an inactive form, thus when targeted to specific organs and tissues they have local pharmacologic activity avoiding systemic effects. Prostones possess a unique mechanism of action as highly potent and selective ion channel activators. Ion channels are integral parts of cell membranes that regulate the flow of specific ions into and out of cells. This regulation is key to the functioning of cells, such as metabolic processes and cell survival. As such, prostones are physiological mediators of the restoration of cellular homeostasis and tissue regeneration. There is also evidence that prostones have anti-inflammatory properties and can prevent cell death.

The Company’s prostone-based compounds target the ClC-2 and big potassium, or BK, ion channels. Because these ion channels play an important role in physiology, targeted dosing of prostones may have broad applicability in many disease states in different organ systems. The Company has developed synthetic analogs of the naturally occurring prostones, which have been optimized to be more potent, selective, and stable, thus enabling their use as drugs. Prostones are very selective for their molecular targets, and the approved prostone-based compounds are well-tolerated and generally safe.

The Company is focused on developing prostones to treat gastrointestinal, ophthalmic,  neurologic, and oncology-based inflammatory disorders, and is alsoconsidering other potential therapeutic applications of the Company’s drug platform.

The Companycurrently generates revenue mainly from product royalties, development milestone payments, clinical development activities and product sales. The Company expects to continue to incur significant expenses for the next several years as the Company continuesits research and development activities, seeks regulatory approvals and additional indications for AMITIZA^® (lubiprostone), RESCULA^®(unoprostone isopropyl) and other compounds, and commercializes the Company’s approved products on a global basis.

To date, two prostone products-, AMITIZA and RESCULA, have received marketing approval globally. A third prostone, cobiprostone, or SPI-8811, is in phase 1 clinical development for the target indication of prevention of oral mucositis, or OM. Twoadditional prostones, SPI-017 and SPI-3608, have also been developed for human testing for the indication of management of pain caused by spinal stenosis, and SPI-017 is currently in a phase 2A trial that is expected to conclude by the fourth quarter of 2013.

AMITIZA is currently being marketed in the United States for two gastrointestinal indications under the October 2004 collaboration and license agreement with Takeda Pharmaceutical Company Limited, or the Takeda Agreement. AMITIZA will be marketed under the Takeda Agreement for a third gastrointestinal indication in the second quarter of 2013. These indications are chronic idiopathic constipation, or CIC,in adults; irritable bowel syndrome with constipation, or IBS-C, in adult women; and opioid-induced constipation, or OIC,in adult patients with chronic, non-cancer pain, which received approval from the FDA in April 2013. AMITIZA at dosage strength of 24 micrograms twice daily is the first and only oral medication for the treatment of OIC in adult patients with chronic, non-cancer pain.  Takeda also holds marketing rights to AMITIZA in Canada, but has yet to commercialize in that market.  The Company is primarily responsible for development activities under the Takeda Agreement while Takeda is responsible for commercialization of AMITIZA in the United States and Canada. The Company and Takeda initiated commercial sales of AMITIZA in the United States for the treatment of CIC in April 2006 and for the treatment of IBS-C in May 2008.  

In Japan, AMITIZA is currently marketed under a license,  commercialization and supply agreement, or the Abbott Agreement,with Abbott Japan Co. Ltd., or Abbott,for the gastrointestinal indication of chronic constipation, or CC,excluding constipation caused by organic diseases.Abbott initiated commercial sales of AMITIZA in Japan for the treatment of CC in November 2012.

In the United Kingdom,  the Company is currently working to achieve National Institute for Health and Care Excellence, or NICE, endorsement and launch in the United Kingdom in 2013. In Switzerland, the Company is actively marketing AMITIZA, following an agreement on a reimbursement price with the Swiss Bundesamt für Gesundheit (BAG) in December 2012. AMITIZA has also been made available through a Named Patient Program throughout the European Union, Iceland and Norway since February 2012.

In the first quarter of 2013, the Company commenced the approval process in other European Union countries for CIC via the Mutual Recognition Procedure, or MRP and filed for the OIC indication in the United Kingdom and Switzerland. If the Company receives approval for OIC in the United Kingdom, the Company will seek approval in other European Union countries following the MRP for OIC.

The Company holds license agreements for RESCULAin the United States and Canada and the rest of the world, with the exception of Japan, Korea, Taiwan and the People’s Republic of China.The Company has begun commercializing RESCULA (unoprostone isopropyl ophthalmic solution) 0.15% for the lowering of intraocular pressure, or IOP, in patients with open-angle glaucoma or ocular hypertension.According to the approved product labeling, RESCULA may be used as a first-line agent or concomitantly with other topical ophthalmic drug products to lower intraocular pressure.RESCULA is a BK channel activator, and thus acts via a mechanism of action, entirely different from any other IOP lowering agent on the market.

In other areas of development, the Company entered into agreements in 2011 with CuroNZ of New Zealand, with the aim to augment the Company’s ophthalmic development opportunities. In the first quarter of 2013, the Company decided to no longer support the development of the peptide compound. Additionally, in 2011, the Company entered into an agreement with Numab AG, or Numab, of Switzerland, to obtain access to their proprietary technology for the discovery of high-affinity antibodies against certain selected targets.In the first quarter of 2013, the Company decided to no longer pursue the further development of the target.

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP, and the rules and regulations of the Securities and Exchange Commission, or SEC, for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s Consolidated Financial Statements as of and for the year ended December 31, 2012 included in the Company’s Annual Report on Form 10-K, which was filed with the SEC on March 18, 2013. The financial information as of March 31, 2013 and for the three months ended March 31, 2013 and 2012 is unaudited. In the opinion of the Company’s management, all adjustments, consisting only of normal recurring adjustments or accruals, considered necessary for a fair statement of the results of these interim periods have been included. The results of the Company’s operations for any interim period are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year.

The Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries.All significant inter-company balances and transactions have been eliminated.

The preparation of financial statements in conformity with GAAP requires management to make estimates that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Income Taxes [Abstract]

Income Taxes

12.Income Taxes

For the three months ended March 31, 2013 and 2012, the Company recorded a tax provision of $1.1 million and $2.3 million, respectively. The tax provision for the three months ended March 31, 2013 and 2012 primarily pertained to pre-tax profits generated by the Company’s U.S and Japanese subsidiaries.

The Company has estimated its annual effective tax rate for the full fiscal year 2013 and 2012 and applied that rate to its income before income taxes in determining its income tax provision for the interim periods. Non-recurring and discrete items that impact tax expense are recorded in the period incurred.

Uncertain Tax Positions

The Company applies the relevant guidance for uncertainty in income taxes that requires the application of a more likely than not threshold to the recognition and derecognition of uncertain tax positions.

The Company had an outstanding non-current income tax liability of approximately $1.0 million, including interest, for uncertain tax positions as of March 31, 2013. The amount represented the aggregate tax effect of differences between tax return positions and the amounts otherwise recognized in the Company’s Condensed Consolidated Financial Statements. As of March 31, 2013, $549,000 and $475,000 is reflected as other current liabilities and other liabilities, respectively in the accompanying Condensed Consolidated Balance Sheets. The liability for uncertain tax positions as of March 31, 2013 mainly pertained to the Company’s interpretation of nexus in certain states related to revenue sourcing for state income tax purposes. During the three months ended March 31, 2013, the liability for income taxes has decreased approximately $108,000. This decrease in the liability is primarily related to the filing of voluntary disclosures and tax returns with various state tax authorities during the quarter offset by an increase related to current year activity in the United States.  

The Company recognizes accrued interest and penalties related to uncertain tax positions as a component of the income tax provision. Other than the expected settlement of state tax liabilities, no additional uncertain tax positions have been identified for which it is reasonably possible that the total amount of liability for unrecognized tax benefits will significantly increase or decrease within 12 months, except for recurring accruals on existing uncertain tax positions. In addition, future changes in the unrecognized tax benefits would have an effect on the effective rate when recognized.

Segment Reporting

13.Segment Reporting

The Company has determined that it has three reportable segments based on the Company’s method of internal reporting, which disaggregates business by geographic location. These segments are the Americas, Europe and Asia. The Company evaluates the performance of these segments based on income (loss) from operations, as well as other factors, that depend on the development status of these geographies. Such measures include the progress of its research and development activities, collaboration and licensing efforts, commercialization activities, product sales and other factors. The reportable segments have historically derived their revenue from joint collaboration and strategic alliance agreements. Transactions between the segments consist primarily of loans and the provision of research and development services. Following is a summary of financial information by reportable geographic segment:

9.Notes Payable

In November 2010, the Company’s Japanese subsidiary, Sucampo Pharma Ltd., or SPL, entered into a ¥1,000,000,000, approximating $10.6 million as of the closing date, secured term loan agreement with The Bank of Tokyo-Mitsubishi UFJ, Ltd, or the Tokyo-Mitsubishi Bank. The loan agreement provides for the extension of credit for the period of one year that can be renewed annually upon the agreement of the Company, SPL and the Tokyo-Mitsubishi Bank. The loan was renewed in November 2012. Borrowings may be used to finance research and development activities, for working capital needs and for the general corporate purposes of SPL. The loan bears annual interest based on the three-month Tokyo Interbank Offer Rate, or TIBOR, plus 1% and is reset quarterly. The interest rate at March 31, 2013 was 1.27%. The outstanding loan balances included in the accompanying Condensed Consolidated Balance Sheets were $10.6 million and $11.6 million as of March 31, 2013 and December 31, 2012, respectively. In connection with the loan agreement, the Company and the Tokyo-Mitsubishi Bank executed a guarantee agreement which provides full guarantee by the Company on behalf of SPL’s obligation to the Tokyo-Mitsubishi Bank. The loan agreement includes representations, covenants, and events of default customary for financing transactions of this type. Additionally, the Company agreed to maintain an amount of collateral that would not fall below 90.0% of the initial balance throughout the term of the loan.

The outstanding loan balance included in the accompanying Condensed Consolidated Balance Sheets was  $10.6 million as of March 31, 2013. The loan agreement includes representations, covenants, and events of default customary for financing transactions of this type. Additionally, SPL agreed to maintain an amount of collateral that would not fall below 100.0% of the initial balance throughout the term of the loan.

In connection with the December 2010acquisition of Sucampo AG, orSAG, and its wholly owned subsidiary SAG-J, Ambrent Investments S.à r.l., or Ambrent, issued a subordinated unsecured promissory note, or notes, to each of the Ueno Trust and Kuno Trust, each a related party. Each of the notes was issued with an initial principal balance of approximately $25.9 million, or approximately $51.9 million in the aggregate.The interest rate for the notes is equal to the per annum rate of interest determined on the basis of the sum of London Interbank Offered Rate, or LIBOR, plus 4.0%, and is reset every six months on December 1st and June 1st of each year.The interest rate beginning December 1, 2012 is 4.5%.

The notes provide for a semi-annual repayment schedule of interest and principal over a seven-year period on each June 1st and December 1st, provided that, until December 1, 2012, all accrued and unpaid interest was not be paid in cash and was instead added to the principal balance of the notes, and Ambrent made only two scheduled principal payments on December 1, 2011 and December 1, 2012. In November 2011, Ambrent made the first principal payment of $7.5 million. In November 2012, Ambrent made the second principal payment of $7.5 million. Interest was approximately $460,000 for the three months ended March 31, 2013.

The notes can be prepaid at any time without penalty. In addition, the notes provide for a mandatory prepayment (i) in full in the event of an acquisition by an unaffiliated third party in an all-cash acquisition of all of the issued and outstanding shares of capital stock of the Company or (ii) either in full or in part in certain change of control transactions involving the Company where an unaffiliated third party acquires a majority of the Company’s voting stock.

Beginning October 2012, R-Tech is relocating its manufacturing facility for unoprostone isopropyl and will not be able to manufacture and supply unoprostone isopropyl for up to 18 months. R-Tech has designated another facility in Japan but such facility will need to be inspected by the FDA in 2013 before it can manufacture unoprostone isopropyl. In order to mitigate this risk, the Company placed an order of $5.3 million to cover this supply period based on Company forecasts for the launch of RESCULA in the United States, R-Tech delivered $4.5 million of that order to the Company in the first quarter of 2013.

Numab AG

In September 2011, the Company entered into a Loan Guarantee and Development Agreement, or the Numab Agreement, with Numab. Numab is considered a related party as a result of an ownership interest by one of our executive officers. Under the terms of the Numab Agreement the Company will provide Numab with up to CHF 5.0 millionas collateral and will serve as guarantor for a loan to Numab from a third party. Following payment of the first success fee during the quarter this amount was reduced to CHF 2.2 million, approximately $2.3 million as of the closing date,The Companymay name up tothree further targets against which Numab will use their proprietary technology to discover high-affinity antibodies and to develop these to an investigational new drug ready stage. Numab is eligible for full time equivalent based payments and discovery success dependent fees. Any success dependent fees will result in a corresponding reduction in the amount of the available guarantee.

As of March 31, 2013, the collateral of CHF 2.2 million has been deposited by the Company and Numab has utilized CHF 2.0 million of its CHF 2.0 million loanDuring 2012 we considered it probable the success criteria for the first target would be met and made full provision for the success fee. This fee was paid during the first quarter of 2013. The Company has decided to no longer pursue the further development of the target. Numab and the Company are in discussions in light of this decision.

Summary Of Significant Accounting Policies [Abstract]

Cash And Cash Equivalents

Cash and Cash Equivalents

For the purpose of the Condensed Consolidated Balance Sheets and Statements of Cash Flows, cash equivalents include all highly liquid investments with a maturity of 90 days or less at the time of purchase.

Restricted Cash

Restricted Cash

Restricted cash consists of approximately $28.4 million and $18.9million at March 31, 2013 and December 31, 2012, respectively.  Restricted cash represents cash required to be deposited with certain financial institutions in connection with a loan agreement with The Bank of Tokyo-Mitsubishi UFJ, Ltd., a loan agreement with Mizuho Bank, Ltd., Numab’s loan with Zurcher Kantonalbank and operating leases.

Current And Non-current Investments

Current and Non-current Investments

Current and non-current investments consist primarily of United States government agency securities, certificates of deposits and variable rate demand notes. The Company classifies its investments into current and non-current based on their maturities and management’s reasonable expectation to realize these investments in cash. The Company classifies all of its investments as available for sale securities and reports unrealized gains or losses, net of related tax effects,in other comprehensive income.

Fair Value Of Financial Instruments

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, which include cash and cash equivalents, restricted cash, current and non-current investments, receivables, accounts payable and accrued expenses, approximate their fair values based on their short maturities, independent valuations or internal assessments.The carrying amount of the notes payable at March 31, 2013 was less than the estimated fair value and at December 31, 2012 approximated its fair value.The Company’s debt is subject to the fair value disclosure requirements as discussed in Note 4 below, is considered a Level 2 security.

Accounts Receivable And Unbilled Accounts Receivable

Accounts Receivable and Unbilled Accounts Receivable

Accounts receivable represent mainly amounts due under the Takeda and the Abbott Agreements. Unbilled accounts receivable represent the research and development expenses that are reimbursable by Takeda but have not been billed to Takeda as of the balance sheet date. The Company recorded an allowance for doubtful accounts at March 31, 2013 and December 31, 2012 of approximately $354,000 and $280,000, respectively, related to certain disputed Takeda invoices.

Product Royalties Receivable

Product Royalties Receivable

Product royalties receivable represent amounts due from Takeda for the Company’s royalties on sales of AMITIZA, which are based on reports obtained directly from Takeda.

Revenue Recognition

Revenue Recognition

The Company’s revenuesare derived primarily from collaboration and license agreements and include upfront payments, development milestone payments, reimbursements of development and co-promotion costs, product sales and product royalties.

Research And Development Revenue

Research and Development Revenue

The Company evaluated the multiple deliverables within the collaboration and license agreements in accordance with the guidance of multiple deliverables to determine whether the delivered elements that are the obligation of the Company have value to other parties to the agreement on a stand-alone basis and whether objective reliable evidence of fair value of the undelivered items exists. Deliverables that meet these criteria are considered a separate unit of accounting. Deliverables that do not meet these criteria are combined and accounted for as a single unit of accounting. The appropriate recognition of revenue is then applied to each separate unit of accounting. The Company’s deliverables under the Takeda Agreement and the Abbott Agreement, including the related rights and obligations, contractual cash flows and performance periods, are more fully described in Note 10 below.

Product Royalty Revenue

Product Royalty Revenue

Royalty revenues are based on net sales of licensed products and are recorded on the accrual basis when earned in accordance with contractual terms when third-party results are reliably measurable, collectability is reasonably assured and all other revenue recognition criteria are met.

Product Sales Revenue

Product Sales Revenue

AMITIZA product sales consist of AMITIZA sales to Abbott in Japan. Revenue from AMITIZA product sales is recognized when persuasive evidence of an arrangement exists, delivery has occurred and title to product and associated risk of loss have passed to the customer, the price is fixed or determinable, and collection from the customer is reasonably assured. The Company did not record sales deductions and returns for sales of AMITIZA to Abbott due to the absence of discounts and rebates and no right of return under the contract with Abbott.

RESCULA product sales consist of RESCULA sales in the United States. The Company recognizes revenue from RESCULA product sales less deductions for estimated sales discounts and sales returns. Revenue from product sales of RESCULA is recognized when persuasive evidence of an arrangement exists, title passes, the price is fixed or determinable, and collectability is reasonably assured. The Company accounts for rebates to certain governmental agencies as a reduction of product sales. The Company allows customers to return product within a specified time period prior to and subsequent to the product’s labeled expiration date. As a result, the Company estimates an accrual for product returns, which is recorded as a reduction of product sales. Given the Company’s limited history of selling RESCULA and the return period, the Company cannot reasonably estimate product returns from the wholesale distribution channel. Therefore the Company is deferring the recognition of revenue until there is confirmation of pull through sales to pharmacies or other end user customers. We will continue to defer recognition until the point at which we have obtained sufficient sales history to reasonably estimate returns from the wholesalers. Our three largest wholesale customers accounted for 89.9% of our RESCULA product sales for the three months ended March 31, 2013.

Co-Promotion Revenue

Co-promotion Revenue

Co-promotion revenues relate to reimbursements of co-promotion costs based upon a rate per detail and reimbursements of the costs of miscellaneous marketing activities.

Contract And Collaboration Revenue

Contract and Collaboration Revenue

Contract revenue relates to development and consulting activities and is accounted for under the time-based model.

The Company considers its participation in the joint committees under the collaboration and license agreements as separate deliverables under the contracts and recognizes the fair value of such participation as collaboration revenue over the period of the participation per the terms of the contracts.

The Company has determined that it is acting as a principal under both the Takeda Agreement and Abbott Agreement and, as such, records revenue on a gross basis in the Condensed Consolidated Statements of Comprehensive Income (Loss).

Cost Of Good Sold

Cost of Goods Sold

Cost of goods sold relates to sales and distribution of the Company’s products sold by the Company.

Certain Risks, Concentrations And Uncertainties

Certain Risks, Concentrations and Uncertainties

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash and cash equivalents, restricted cash, investments and receivables. The Company places its cash, cash equivalents and restricted cash with highly rated financial institutions and invests its excess cash in highly rated investments.  As of March 31, 2013 and December 31, 2012, approximately $15.7 million, or 16.4%, and $15.6 million, or 16.7%, respectively, of the Company’s cash, cash equivalents, restricted cash and investments were issued or insured by the federal government or government agencies.The Company has not experienced any losses on these accounts related to amounts in excess of insured limits.

The Company’s products and product candidates under development require approval from the FDA or other international regulatory agencies prior to commercial sales. For those product candidates or indications that have not yet been approved by the FDA or international regulatory agencies, there can be no assurance the products will receive the necessary approval. If the Company is denied approval or approval is delayed, it may have a material adverse impact on the Company.

The Company’s products, AMITIZA and RESCULA, compete in a rapidly changing, highly competitive market, which is characterized by advances in scientific discovery, changes in customer requirements, evolving regulatory requirements and developing industry standards. Any failure by the Company to anticipate or to respond adequately or timely to scientific developments in its industry, changes in customer requirements or changes in regulatory requirements or industry standards, or any significant delays in the development or introduction of products could have a material adverse effect on the Company’s business, operating results and future cash flows.

The Company’s expected activities may necessitate significant uses of working capital. The Company’s working capital requirements will depend on many factors, including the successful sales of AMITIZA and RESCULA, research and development efforts to develop new products or indications, payments received under contractual agreements with other parties, the status of competitive products and market acceptance of the Company’s new products by physicians and patients. The Company plans to continue financing operations with its existing cash and investments as well as with product royalty revenue and cash received from milestones and other revenue related to its joint collaboration, license and supply agreements.

Revenues from one unrelated party, Takeda, accounted for 86.8% and98.3%,  of the Company’s total revenues for the three months ended March 31, 2013 and 2012, respectively. Accounts receivable, unbilled accounts receivable and product royalties receivable from Takeda accounted for97.2%  and 98.0%  of the Company’s total accounts receivable, unbilled accounts receivable and product royalties receivable at March 31, 2013 and December 31, 2012, respectively.  Revenues from another unrelated party, Abbott, accounted for13.1% and 1.0%  of the Company’s total revenues for the three months ended March 31, 2013 and 2012, respectively.The Company depends significantly upon the collaborations with Takeda and Abbott and its activities may be impacted if these relationships are disrupted.

The Company has an exclusive supply arrangement with R-Tech to provide it with commercial and clinical supplies of its product and product candidates. R-Tech also provides certain preclinical and other research and development services. Any difficulties or delays in performing the services under these arrangements may cause the Company to lose revenues, delay research and development activities or otherwise disrupt the Company’s operations (Note 8).

The Company performs fair value measurements in accordance with the FASB’s guidance for fair value measurements and disclosures, which defines fair value as the exchange price that would be received for selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A fair value hierarchy is established which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company classifies its investments into the following categories based on the three levels of inputs used to measure fair value:

Level 1: quoted prices in active markets for identical assets or liabilities;

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

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

The Company’s assets measured at fair value on a recurring basis, including cash equivalents, which are subject to the fair value disclosure requirements, are as follows:

If quoted prices in active markets for identical assets and liabilities are not available to determine fair value, then the Company uses quoted prices for similar assets and liabilities or inputs other than the quoted prices that are observable, either directly or indirectly. This pricing methodology applies to the Company’s Level 2 investments.

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP, and the rules and regulations of the Securities and Exchange Commission, or SEC, for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s Consolidated Financial Statements as of and for the year ended December 31, 2012 included in the Company’s Annual Report on Form 10-K, which was filed with the SEC on March 18, 2013. The financial information as of March 31, 2013 and for the three months ended March 31, 2013 and 2012 is unaudited. In the opinion of the Company’s management, all adjustments, consisting only of normal recurring adjustments or accruals, considered necessary for a fair statement of the results of these interim periods have been included. The results of the Company’s operations for any interim period are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year.

The Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries.All significant inter-company balances and transactions have been eliminated.

The preparation of financial statements in conformity with GAAP requires management to make estimates that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
