&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On February 8, 2012, the Company amended its shelf registration statement, originally filed on January 26, 2012, with the SEC, under which the Company may offer shares of its common stock and preferred stock, various series of debt securities and/or warrants to purchase any of such securities, either individually or in units, in one or more offerings, up to a total dollar amount of $100,000,000. Such registration statement, as amended, became effective as of February 9, 2012. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On January 11, 2012, the Company raised gross proceeds of approximately $23.7 million through the sale of 4,989,275 shares of its common stock in a publicly-marketed offering.

Such registration statement became effective as of January 19, 2011. Upon completion of this offering, there were no securities remaining under the 2011 shelf. &lt;/font&gt;&lt;/p&gt;

At December 31, 2011, the Company held short-term investments of $4.5 million, consisting of an investment in a certificate of deposit, or CD, with a maturity of 26-weeks as of the date of purchase. This investment was purchased through the Certificate of Deposit Account Registry Service, or CDARS&lt;font style="font-family: Times New Roman;" class="_mt" size="1"&gt;&lt;sup style="position: relative; bottom: 0.8ex; vertical-align: baseline;"&gt;&amp;#174;&lt;/sup&gt;&lt;/font&gt;. Investments are made through a single CDARS Network member and when a large deposit is made, that institution uses the CDARS service to place funds into CDs issued by other members of the CDARS Network. Investments occur in increments below the standard Federal Deposit Insurance Corporation, or FDIC, insurance maximum ($250,000) so that both principal and interest are eligible for FDIC insurance. During the quarter ended March 31, 2012, this short-term investment matured and was fully redeemed. &lt;/font&gt;&lt;/p&gt; &lt;/div&gt;</us-gaap:CashCashEquivalentsAndShortTermInvestmentsTextBlock>

&lt;p style="margin-top: 6px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;License Agreements &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In March 2004, the Company entered into a license agreement with Dr. M. Gopal Nair, Ph.D., of the University of South Alabama College of Medicine, for the rights to use, produce, distribute and market products derived from an invention by Dr. Nair, claimed in US Patent # 5,912,251, entitled "metabolically inert anti-inflammatory and antitumor antifolates", designated by the Company as CH-1504 and related compounds. The license provides the Company exclusive, worldwide (excluding India) rights for CH-1504 and related compounds. The Company made an upfront payment in May 2004 of $150,000 and milestone payments as required by the agreement of $100,000 each in March 2006 and 2005. In April 2007, the Company issued 26,643 shares of its common stock, subject to trading restrictions, at a value of approximately $5.63 per share, in settlement of the $150,000 annual milestone payment liability. In March 2008, the Company made a milestone payment of $100,000 related to patient dosing in a Phase II study as required by the agreement. In April 2008, the Company issued 30,612 shares of its common stock, subject to trading restrictions, at a value of approximately $4.90 per share, in settlement of the 2008 anniversary milestone payment. In April 2009, the Company made the 2009 anniversary milestone payment of $150,000. In September 2010, the Company made a milestone payment of $100,000 related to patient dosing in a Phase II study as required by the agreement. The Company is obligated to pay royalties under the agreement until the later of the expiration of the applicable patent or the applicable last date of market exclusivity after the first commercial sale, on a country-by-country basis. There are no minimum royalties required under the agreement. The Company is also obligated to make future potential milestone payments based on the achievement of specific development and regulatory approval milestones. Based on the Company's current development plans for compounds licensed under this agreement, approximately $1.5 million of payments may become due if specific milestones are achieved, subject to the Company's right to terminate the license agreement. In addition, should the Company enter into an out-licensing agreement, such payments could be offset by revenue received from the sub-licensee. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In May 2006, the Company entered into an agreement with Dainippon Sumitomo Pharma Co., Ltd. ("DSP") for a worldwide, exclusive, sub-licensable license and rights to certain intellectual property and proprietary information (the "DSP Agreement") relating to L-threo-3,4-dihydroxyphenylserine ("L-DOPS" or "droxidopa") including, but not limited to all information, formulations, materials, data, drawings, sketches, designs, testing and test results, records and regulatory documentation. As consideration for these rights, the Company paid DSP $100,000 and issued 63,131 shares of its common stock, with a value of approximately $4.35 per share, or $274,621. As additional consideration, the Company agreed to pay DSP and/or its designees (1) royalties on the sales should any compound be approved for commercial sale, and (2) milestone payments, payable upon achievement of milestones as defined in the DSP Agreement. In February 2008, the Company made a milestone payment under the DSP Agreement of $500,000 related to patient dosing in a Phase III study. In December 2011, the Company made a milestone payment under the DSP Agreement of $750,000 related to submission of an NDA to the FDA and has remaining potential future milestone payments, subject to the Company's right to terminate the DSP Agreement, totaling $2.5 million. The Company and DSP also initiated, and the Company agreed to fund, activities focused on modifying the manufacturing capabilities of DSP in order to expand capacity and comply with regulations and requirements of the FDA. Based on work performed by DSP as of March 31, 2012, the Company had recorded expense of approximately $3.1 million and had a remaining liability of approximately $5,000. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In conjunction with and as consideration for activities related to the execution of the DSP Agreement, the Company entered into a Finder's Agreement with Paramount BioCapital, Inc. ("Paramount"). In May 2006, pursuant to the Finder's Agreement, the Company issued warrants for the purchase of 250,000 shares of its common stock at an exercise price of $4.31 per share. The exercise of these warrants was conditioned on an event that occurred in January 2007 and, accordingly, the Company recorded a charge for the fair value of the warrants at January 2007 of $433,750. The Company utilized the Black-Scholes-Merton valuation model for estimating the fair value of the warrants at the date the condition lapsed, based on a risk-free interest rate of 4.79%, an expected life of three years, an expected dividend yield of 0%, an expected volatility of 66.01% and no estimated forfeitures. As additional consideration, the Company agreed to (1) make future milestone payments to Paramount, upon achievement of milestones as defined in the Finder's Agreement, (2) pay royalties on sales should any licensed compound become available for commercial sale, and (3) compensate a stated third-party consultant for services rendered in the evaluation of the transaction with DSP. The Company has remaining potential future milestone payments under the Finder's Agreement of $150,000. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Contract Research and Manufacturing Purchase Obligations &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company often contracts with third parties to facilitate, coordinate and perform agreed upon research and development and manufacturing activities. These contracts typically call for the payment of fees for services at the initiation of the contract and/or upon the achievement of certain milestones. The Company currently intends to continue its research and manufacturing activities as contracted at March 31, 2012. However, should a need arise to cancel these contracted activities, there can be cancellation fees that could be punitive in nature. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In October 2011, the Company committed to the purchase of active pharmaceutical ingredient from a third party to be used in the production of commercial inventory in preparation for the planned market launch of Northera in the United States. The scale-up and commercial production of pre-launch inventories involves the risk that such products may not be approved for marketing by the appropriate regulatory agencies on a timely basis, or ever. This risk notwithstanding, the Company initiated such activities with its primary supplier of active pharmaceutical ingredient of Northera in December 2010 and has incurred expenses related to these activities of approximately $1.2 million and $1.9 million during the quarters ended March 31, 2012 and 2011, respectively. Until final approval to market any of the Company's product candidates is received from the appropriate regulatory agencies, such costs are expensed to research and development. The value of the remaining obligation totals approximately $5.8 million as of March 31, 2012 given current exchange rates. Although the remainder of this material could be shipped at any time chosen by the Company within a two-year period following the completion of its manufacture, the Company currently does not anticipate it will be shipped prior to 2013, at the earliest. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Legal Proceedings &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Following the receipt of the CRL in March 2012 and the subsequent decline of the market price of the Company's common stock, two purported class action lawsuits were filed on April 4, 2012 and another purported class action lawsuit was filed on May 1, 2012 in the U.S. District Court for the Western District of North Carolina against the Company and certain of its executive officers. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The complaints generally allege that, during differing class periods, all of the defendants violated Sections 10(b) of the Securities Exchange Act of 1934, or the Exchange Act, and SEC Rule 10b-5 and the individual defendants violated Section 20(a) of the Exchange Act in making various statements related to the Company's development of Northera for the treatment of symptomatic neurogenic orthostatic hypotension and the likelihood of FDA approval. The class periods alleged in the three complaints run from November 3, 2008 to March 28, 2012 for two of the complaints and from June 9, 2011 to February 17, 2012 for the other. The complaints seek unspecified damages, interest, attorneys' fees, and other costs. Additional similar lawsuits might be filed. The Company and its officers believe that all of the claims in these lawsuits are without merit and the Company intends to vigorously defend against these claims, but is unable to predict the outcome or reasonably estimate a range of possible loss. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Other Contractual Obligations &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;During 2011, the Company contracted with various third parties to facilitate, coordinate and perform agreed upon commercialization support activities in anticipation of the planned launch of Northera. These contracts typically call for the payment of fees for services at the initiation of the contract and/or upon the achievement of certain milestones. The Company is currently evaluating each of these activities as contracted given the receipt of the CRL on March 28, 2012 to determine which, if any, of these contracts should be cancelled or delayed. Should a need arise to cancel activities under these contracts, there might be cancellation fees that could be punitive in nature. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Business activities being performed under these contracts include, but are not limited to, market research, marketing and advertising planning and development, contracted Medical Science Liaison professionals, sales territory mapping, publication planning, sales force recruiting, sales operations support and planning, messaging and website development, public relations and information technology support and planning. &lt;/font&gt;&lt;/p&gt; &lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The aggregate intrinsic value is calculated as the difference between the exercise prices of the underlying awards and the quoted closing price of the common stock of the Company as of March 31, 2012 and only include those awards that have an exercise price below the quoted closing price, or in-the-money options. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Each option granted to employees and non-employee directors during the three months ended March 31, 2012 and 2011 vests as to 25% of the shares on each of the first, second, third and fourth anniversary of the vesting commencement date. Following the vesting periods, options are exercisable by employees until the earlier of 90 days after the employee's termination with the Company or the ten-year anniversary of the initial grant, subject to adjustment under certain conditions. Following the vesting periods, options are exercisable by non-employee directors until the earlier of 180 days after they cease to be a member of the Board of Directors or the ten-year anniversary of the initial grant, subject to adjustment under certain conditions. As of January 2012, options that are forfeited or cancelled are not returned to the option pool and are, accordingly, no longer eligible for grant under the Plan. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The fair value of each option award made to employees and directors was estimated on the date of grant using the Black-Scholes-Merton closed-form option valuation model utilizing the assumptions noted in the following table. As of January 1, 2011, the Company began relying exclusively on the trading and price history of the Company's stock in order to determine the expected volatility given that, as of that date, there existed sufficient trading history to be able to determine historical volatility. The Company plans to continue to analyze the expected stock price volatility, as well as other assumptions utilized in the calculations, at each grant date as more historical data becomes available. Also as of January 1, 2011, taking into consideration hiring completed and planned by the Company and the potential impact of forfeitures given the roles of these newly filled positions, the Company estimated a forfeiture rate of 3%. Due to the limited amount of historical data available to the Company, particularly with respect to employee exercise patterns and forfeitures, actual results could differ from the Company's assumptions. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Basic net loss per common share is calculated by dividing net loss by the weighted-average number of common shares outstanding for the period, without consideration for potentially dilutive securities. For the periods presented, basic and diluted net loss per common share are identical. Potentially dilutive securities from stock options and stock warrants would be antidilutive as the Company incurred a net loss. The number of shares of common stock potentially issuable at March 31, 2012 and 2011 upon exercise or conversion that were not included in the computation of net loss per share totaled 9,124,960 and 8,913,474 shares, respectively. &lt;/font&gt;&lt;/p&gt;

&lt;td valign="top" align="left"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF OPERATIONS &lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;p style="margin-top: 6px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;The Company &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Chelsea Therapeutics International, Ltd. ("Chelsea Ltd." or the "Company") is a development stage pharmaceutical company focused on the acquisition, development and commercialization of innovative pharmaceutical products. Specifically, the Company is developing Northera&amp;#8482; (droxidopa), a novel therapeutic agent for the treatment of symptomatic neurogenic orthostatic hypotension, or Neurogenic OH, in patients with primary autonomic failure (Parkinson's disease, or PD, multiple systems atrophy, or MSA, and pure autonomic failure, or PAF), dopamine-&amp;#223;-hydroxylase, or DBH, deficiency and non-diabetic autonomic neuropathy. The Company is also evaluating the potential therapeutic applications of droxidopa in reducing the frequency of falls in patients with Neurogenic OH associated with PD as well as other potentially norepinephrine related conditions and diseases including intradialytic hypotension, fibromyalgia and adult attention deficit hyperactivity disorder. In addition, the Company is developing a portfolio of metabolically inert antifolates for the treatment of rheumatoid arthritis that might also be suitable for the treatment of multiple other autoimmune disorders including psoriasis, Crohn's disease, uveitis, ankylosing spondylitis, inflammatory bowel disease, cancer and other immunological disorders. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company's operating subsidiary, Chelsea Therapeutics, Inc. ("Chelsea Inc."), was incorporated in the State of Delaware on April 3, 2002 as Aspen Therapeutics, Inc., with the name changed in July 2004. In February 2005, Chelsea Inc. merged with a wholly-owned subsidiary of Chelsea Ltd.'s predecessor company, Ivory Capital Corporation ("Ivory"), a Colorado public company with no operations (the "Merger"). The Company reincorporated into the State of Delaware in July 2005, changing its name to Chelsea Therapeutics International, Ltd. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;As a result of the Merger of Ivory and Chelsea Inc. in February 2005, and the reincorporation in Delaware in July 2005, Chelsea Ltd. is the reporting company and is the 100% owner of Chelsea Inc. The separate existence of Ivory ceased in connection with the Delaware reincorporation in July 2005. Except where the context provides otherwise, references to the "Company" and similar terms mean Ivory, Chelsea Ltd. and Chelsea Inc. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Basis of Presentation &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The accompanying condensed consolidated financial statements include the accounts of the Company and its operating subsidiary, which shall collectively be referred to as the "Company". These statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and the instructions to Form 10-Q and do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of the Company's management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the results for the interim periods have been included. Operating results for the three months ended March 31, 2012 are not necessarily indicative of the results for the year ending December 31, 2012 or future periods. The accompanying condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K filed on March 7, 2012 and available on the website (&lt;u&gt;www.sec.gov&lt;/u&gt;) of the United States Securities and Exchange Commission, or the SEC. The accompanying condensed consolidated balance sheet as of December 31, 2011 has been derived from the audited balance sheet as of that date included in the Form 10-K. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Since inception, the Company has focused primarily on organizing and staffing, negotiating in-licensing agreements with partners, acquiring, developing and securing its proprietary technology, participating in regulatory discussions with the United States Food and Drug Administration, or FDA, the European Medicines Agency, or EMA and other regulatory agencies and undertaking preclinical trials and clinical trials of product candidates. The Company is a development stage company and has generated no revenue since inception. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;More recently, the Company has been focusing on preparations for the potential commercial launch of Northera in the United States in anticipation of FDA approval. However, on March 28, 2012, the Company announced that the FDA had issued a Complete Response Letter, or a CRL, regarding its New Drug Application, or NDA, for Northera, filed in September 2011, for the treatment of symptomatic Neurogenic OH in patients with primary autonomic failure (PD, MSA and PAF), DBH deficiency and non-diabetic autonomic neuropathy. The CRL includes the request by the FDA that the Company submit data from an additional positive study to support efficacy along with a recommendation that such a study be designed to demonstrate durability of effect over a 2- to 3-month period. Notably, the CRL did not identify any outstanding safety concerns. In addition, the FDA provided draft recommendations to several sections of the labeling submitted for Northera, including a preliminary recommendation to include a black box warning related to supine hypertension. However, the letter indicates that such a boxed warning could be reconsidered if suitable data demonstrating a lack of severe hypertension in a fully prone position were provided. The Company has requested a meeting with the FDA to review the CRL, clinical trial recommendations and to help determine appropriate next steps toward obtaining approval of Northera.&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company has sustained operating losses since its inception and expects that such losses could continue for the foreseeable future. The Company's continued operation depends on its ability to raise funds through various potential sources, such as equity and debt financing, the exercise of warrants or strategic alliances. Such strategic relationships or out-licensing arrangements might require the Company to relinquish rights to certain of its technologies, product candidates or products that the Company would otherwise seek to develop or commercialize itself. If adequate funds are not available, the Company may be required to delay, reduce the scope of, or eliminate one or more of its development programs or curtail operations. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Management believes that capital resources available at March 31, 2012 will be sufficient to meet the operating needs of the Company into the second quarter of 2013. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Basis of Consolidation &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The accompanying financial statements present, on a condensed consolidated basis, the financial position and results of operations of Chelsea Ltd. and its subsidiary. All significant intercompany transactions and balances have been eliminated in consolidation. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Use of Estimates &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements as well as the reported revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates and judgments. Management bases estimates on its historical experience and on various other factors that it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results might differ from these estimates under different assumptions or conditions. &lt;/font&gt;&lt;/p&gt;
