Nature of Business and Significant Accounting Policies
Nature of Business and Significant Accounting Policies	Note 1 - Nature of Business and Significant Accounting Policies Nature of Business: Sunshine Heart (“we” or the “Company”) was founded in November 1999 and incorporated in Delaware in August 2002. The Company’s headquarters are located in Eden Prairie, MN and the Company also has a wholly owned subsidiary, Sunshine Heart Company Pty Ltd, located in Clontarf, New South Wales, Australia. We are a medical device company developing innovative technologies for cardiac and coronary disease. The Company’s primary product, the C-Pulse® Heart Assist System, or C-Pulse Heart System, is an implantable, non-blood contacting, heart assist therapy for the treatment of moderate to severe heart failure, which can be implanted using a minimally invasive procedure. The C-Pulse Heart System is designed to relieve the symptoms of heart failure through the use of counterpulsation technology by enabling an increase in cardiac function, an increase in coronary blood flow, and a reduction in the heart’s pumping load. The Company received approval from the U.S. Food and Drug Administration, or FDA, to conduct a U.S. pivotal clinical trial with the C-Pulse Heart System. Our shares of common stock in the form of CHESS Depositary Interests, or CDIs, were publicly traded in Australia on the Australian Securities Exchange, or ASX, from September 2004 until our delisting on the ASX, effective May 6, 2013. Going Concern: The Company’s financial statements have been prepared and presented on a basis assuming it continues as a going concern. During the years ended December 31, 2012 and 2011 and through March 31, 2013, the Company incurred losses from operations and net cash outflows from operating activities as disclosed in the consolidated statements of operations and cash flows, respectively. At December 31, 2012, we had an accumulated deficit of $79,254 and we expect to incur losses for the foreseeable future. To date, the Company has been funded by private and public equity financings. Although we believe that we will be able to successfully fund our operations, there can be no assurance that we will be able to do so or that we will ever operate profitably. The Company’s ability to continue as a going concern is dependent on the Company’s ability to raise additional capital based on the achievement of existing milestones as and when required. Should the future capital raising not be successful, the Company may not be able to continue as a going concern. Furthermore, the ability of the Company to continue as a going concern is subject to the ability of the Company to develop and successfully commercialize the product being developed. If the Company is unable to obtain such funding of an amount and timing necessary to meet its future operational plans, or to successfully commercialize its intellectual property, the Company may be unable to continue as a going concern. No adjustments have been made relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company not continue as a going concern. Basis of Presentation: The accompanying consolidated financial statements include the accounts of Sunshine Heart, Inc. and its wholly-owned subsidiary, Sunshine Heart Company Pty Ltd. (collectively, “Sunshine Heart” or the “Company”). All intercompany accounts and transactions between consolidated entities have been eliminated. Unaudited Interim Consolidated Financial Information: The interim balance sheet as of March 31, 2013 and statements of operations and cash flows for the three months ended March 31, 2013 and 2012 and related interim information contained in the notes to these financial statements are unaudited. The accompanying condensed consolidated financial statements have been prepared in accordance with Regulation S-X of the Securities Act of 1933, as amended. In the opinion of management, such unaudited interim consolidated information has been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and includes all adjustments consisting of normal recurring accruals necessary for the fair presentation of this interim information when read in conjunction with the audited financial statements and notes thereto. Certain information and disclosures normally included in the financial statements have been condensed or omitted pursuant to such rules and regulations, although management believes that disclosures are adequate to make information presented not misleading. Results for the three months ended March 31, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013 or any other interim period or for any other future year. Use of Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Net Loss per Share: Basic net loss attributable to common stockholders, on a per share basis, is computed by dividing income available to common stockholders (the numerator) by the weighted-average number of common shares outstanding (the denominator) during the period. Shares issued during the period and shares reacquired during the period are weighted for the portion of the period that they were outstanding. The computation of diluted earnings per share, or EPS, is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if the dilutive potential common shares had been issued and computed in accordance with the treasury stock method. In addition, in computing the dilutive effect of convertible securities, the numerator is adjusted to add back the after-tax amount of interest recognized in the period associated with any convertible debt. Shares reserved for outstanding stock warrants and options totaling 2,746,497 and 1,961,633 for the three months ended March 31, 2013 and 2012, respectively, were excluded from the computation of loss per share as their effect was antidilutive due to the Company’s net loss in each of those periods. Fair Value of Financial Instruments: Our financial instruments consist of cash, accounts payable and accrued liabilities. We believe that the carrying amounts of the financial instruments approximate their respective current fair values due to their relatively short maturities. Pursuant to the requirements of the Fair Value Measurements and Disclosures Topic of the Financial Accounting Standards Board, or FASB, Codification, the Company’s financial assets and liabilities measured at fair value on a recurring basis are classified and disclosed in one of the following three categories: Level 1: Financial instruments with unadjusted quoted prices listed on active market exchanges. Level 2: Financial instruments lacking unadjusted, quoted prices from active market exchanges, including over the counter traded financial instruments. The prices for the financial instruments are determined using prices for recently traded financial instruments with similar underlying terms as well as directly or indirectly observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3: Financial instruments that are not actively traded on a market exchange. This category includes situations where there is little, if any, market activity for the financial instrument. The prices are determined using significant unobservable inputs or valuation techniques. All cash and cash equivalents are considered Level 1 measurements for all periods presented. We do not have any financial instruments classified as Level 2 or Level 3 and there were no movements between these categories. Recent Accounting Pronouncements: In February 2013, the Financial Accounting Standards Board (“FASB”) issued guidance adding new disclosure requirements for items reclassified out of accumulated other comprehensive income (“AOCI”), which became effective for us in 2013. The guidance is intended to help entities improve the transparency of changes in other comprehensive income (“OCI”) and items reclassified out of AOCI in financial statements. It does not amend any existing requirements for reporting net income or OCI in financial statements. The implementation of the guidance did not have a material impact on our consolidated financial statements.
