Organization and Significant Accounting Policies | Organization and Significant Accounting Policies Organization We are a commercial-stage biopharmaceutical company committed to discovering, developing and commercializing small-molecule and protein therapeutics for large-market as well as orphan indications targeting inflammation, complement-mediated diseases and disorders of the central nervous system. Our first drug product, OMIDRIA, is marketed in the United States (U.S.) for use during cataract surgery or intraocular lens replacement. Basis of Presentation Our condensed consolidated financial statements include the financial position and results of operations of Omeros Corporation (Omeros) and our wholly owned subsidiaries. All inter-company transactions have been eliminated and we have determined we operate in one segment. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The information as of September 30, 2018 and for the three and nine months ended September 30, 2018 and 2017 includes all adjustments, which include normal recurring adjustments, necessary to present fairly our interim financial information. The Condensed Consolidated Balance Sheet at December 31, 2017 has been derived from our audited financial statements but does not include all of the information and footnotes required by GAAP for audited annual financial information. The accompanying unaudited condensed consolidated financial statements and related notes thereto should be read in conjunction with the audited consolidated financial statements and related notes thereto that are included in our Annual Report on Form 10-K for the year ended December 31, 2017 , which was filed with the U.S. Securities and Exchange Commission (SEC) on March 1, 2018. Going Concern On an interim and annual basis we are required to assess our ability to continue as a going concern for one year after the date the financial statements are issued using rules defined by Accounting Standards Codification (ASC) No. 205-40 - Going Concern (the Standard). As required by the Standard, management’s evaluation shall initially not take into consideration the potential mitigating effects of management’s plans that have not been fully implemented as of the date the financial statements are issued. In the second step of this evaluation, management’s assumptions and plans are derived according to restrictions and definitions in the Standard. As such, for purposes of this exercise, the following assumptions (which are discussed in further detail following this summary) were made: • Limited cash receipts from sales of OMIDRIA. Even though we have received an extension of transitional pass-through reimbursement for OMIDRIA for a period of two years effective October 1, 2018, we are unable at this time to predict accurately revenue from sales of OMIDRIA given that transitional pass-through reimbursement for the product has just recently been reinstated. In addition, sales of OMIDRIA are generally made with 90-day collection terms and, therefore, minimal OMIDRIA cash receipts were included for this exercise prior to January 2019; and • No public or private equity transactions or partnering revenues can be considered for purposes of this exercise in the absence of any existing or committed arrangements to raise additional capital or of any existing or consummated partnerships. In performing the first step of the assessment, we concluded that the following conditions raise substantial doubt about our ability to meet our financial obligations as they become due. As of September 30, 2018 , we had $55.2 million in cash, cash equivalents and short-term investments, $2.3 million of accounts receivable and $24.6 million in current liabilities. We have a history of net losses ( $103.2 million for the nine months ended September 30, 2018 ) and use of cash for operations ( $79.1 million for the nine months ended September 30, 2018 ). In performing the second step of this assessment, we are required to evaluate whether our plans to mitigate the conditions above alleviate the substantial doubt about our ability to meet our obligations as they become due within one year after the date the financial statements are issued. In performing this second step of the assessment, we are limited to those assumptions listed above, including nominal revenues from OMIDRIA despite the reinstatement of the product’s pass-through status effective October 1, 2018 pursuant to the Consolidated Appropriations Act of 2018 (Appropriations Act), and the restrictions and definitions in the Standard. Consequently, based on this assessment performed using the associated limitations required by the Standard, we have concluded there is substantial doubt about our ability to continue as a going concern through November 8, 2019. Given our inability to assume any meaningful OMIDRIA sales revenues for the purpose of this exercise due to only recently reinstated pass-through, if we are unable to raise additional equity, debt or partnering capital when needed, or upon acceptable terms, such failure would have a significant negative impact on our financial condition. Should it be necessary to manage our operating expenses, we would reduce our projected cash requirements through reduction of our expenses by delaying clinical trials, reducing research and development efforts, or implementing other restructuring activities. The accompanying consolidated financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The accompanying consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from uncertainty related to our ability to continue as a going concern. Revenue Recognition In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09- Revenue from Contracts with Customers (Topic 606), which requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. We adopted Topic 606 on January 1, 2018 using the modified retrospective transition method. Once we determine that an arrangement is within the scope of Topic 606 and we believe it is probable that we will collect the consideration, we perform the following five steps: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy a performance obligation. Upon adoption, we evaluated our contracts with customers and determined the adoption of the standard did not change the timing or the amounts of our previously recognized revenues. Product Sales, Net We generally record revenue from product sales when the product is delivered to our wholesalers. Product sales are recorded net of wholesaler distribution fees and estimated chargebacks, rebates and purchase volume discounts. Accruals or allowances are established for these deductions in the same period when revenue is recognized, and actual amounts incurred are offset against the applicable accruals or allowances. We reflect each of these accruals or allowances as either a reduction in the related account receivable or as an accrued liability, depending on how the amount is expected to be settled. The Centers for Medicare & Medicaid Services (CMS) initially granted transitional pass-through reimbursement status for OMIDRIA from January 1, 2015 through December 31, 2017. Pass-through status for OMIDRIA allowed for reimbursement payment to Ambulatory Surgery Centers (ASCs) and hospitals using OMIDRIA in procedures involving patients covered by Medicare Part B. In March 2018, the Appropriations Act was signed into law, which among other things extended pass-through reimbursement status for certain drugs, including OMIDRIA, for a two-year period beginning October 1, 2018. For the period January 1, 2018 through September 30, 2018, OMIDRIA was not yet subject to separate reimbursement for procedures involving patients covered by Medicare Part B. Advanced Payments We have various agreements with third parties that require us to pay part of the contractually due amounts in advance of receiving goods and services. These agreements relate primarily to clinical and manufacturing activities. Amounts paid in advance of services to be delivered to us beyond 12 months of the balance sheet date are recorded as non-current assets. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant items subject to such estimates include revenue recognition, stock-based compensation expense and accruals for clinical trials, manufacturing of drug product and clinical drug supply and contingencies. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances; however, actual results could differ from these estimates. Recently Adopted Pronouncements We adopted ASU 2018-05 issued by the FASB in March 2018 related to the Tax Cuts and Jobs Act (Tax Act) that was enacted in December 2017. We remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21.0%. The standard requires that we record and disclose any provisional amounts related to the Tax Act. We recorded and disclosed the provisional impact to our deferred tax balance in our Annual Report on Form 10-K for the year ended December 31, 2017 that was filed with the SEC on March 1, 2018. In May 2016, the FASB issued ASU 2017-09 related to stock-based compensation, which provides guidance on the accounting for changes to the terms and conditions of stock-based payment arrangement, or modifications. We adopted the guidance January 1, 2018 and the adoption did not have a material impact on our stock-based compensation expense. Recent Accounting Pronouncements In August 2018, the FASB issued ASU 2018-15 related to the accounting for cloud computing arrangements and to follow the internal-use software guidance in determining which implementation costs to defer and recognize as an asset. The guidance is effective for annual periods, and interim periods beginning after December 15, 2019. Early adoption is permitted, including adoption in any interim period. We do not expect the adoption of this accounting guidance to have a material impact on our condensed consolidated financial statements. In June 2018, the FASB issued ASU 2018-07 which simplifies the accounting for share-based payments granted to non-employees for services by aligning it with the accounting for share-based payments to employees, with certain exceptions. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We do not expect the adoption of this accounting guidance to have a material impact on our condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 related to lease accounting. The new standard requires lessees to recognize a right-of-use asset and a lease liability for most leases. This standard must be applied using a modified retrospective transition method and is effective for all annual and interim periods beginning after December 15, 2018. We expect to adopt the standard on January 1, 2019 and are still in the process of evaluating the effect of adoption on our consolidated financial statements and are currently assessing our leases. |
