Summary of significant accounting policies | Note 3. Summary of significant accounting policies Principles of consolidation: At March 31, 2016, the consolidated financial statements include the accounts of the Company and its four wholly-owned subsidiaries. At December 31, 2014, Neos Therapeutics, Inc. owned, directly or indirectly, 100% of two of its subsidiaries and 99.9% of the third subsidiary, Neostx, Inc. (“NTX”). The remaining 0.1% ownership of NTX was held by a third party and all such remaining capital stock was acquired by the Company on June 29, 2015, and NTX was merged with and into the Company. The amounts attributable to the noncontrolling interest were not material to the consolidated financial statements. On September 16, 2015, the Company established two new wholly-owned subsidiaries, Neos Therapeutics Brands, LLC and Neos Therapeutics Commercial, LLC. All significant intercompany transactions have been eliminated. Cash equivalents: The Company invests its available cash balances in bank deposits and money market funds. The Company considers highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. Management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. The Company’s primary objectives for investment of available cash are the preservation of capital and the maintenance of liquidity. Short-term investments: Short-term investments consist of debt securities that have original maturities greater than three months but less than or equal to one year and are classified as available-for-sale securities. Such securities are carried at estimated fair value, with any unrealized holding gains or losses reported, net of any tax effects reported, as accumulated other comprehensive income, which is a separate component of stockholders’ equity. Realized gains and losses, and declines in value judged to be other-than-temporary, if any, are included in consolidated results of operations. A decline in the market value of any available-for-sale security below cost that is deemed to be other-than-temporary results in a reduction in fair value charged to earnings in that period, and a new cost basis for the security is established. Dividend and interest income is recognized in other income when earned. The cost of securities sold is calculated using the specific identification method. The Company places all investments with government agencies, or corporate institutions whose debt is rated as investment grade. The Company classifies all available-for-sale marketable securities with maturities greater than one year from the balance sheet date, if any, as non-current assets. Fair value of financial instruments: The carrying value of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, other current assets, accounts payable, accrued expenses, and debt, approximates fair value due to the short-term nature of the instruments and/or the current interest rates payable in relation to current market conditions. The fair value of the Company’s short-term investments and its earnout and warrant liabilities are disclosed in Note 5. Inventories: Inventories, comprised of raw materials, labor, and manufacturing overhead, as well as finished goods inventory, are stated at the lower of cost (actual, which approximates first-in, first-out) or market, net of an allowance for obsolete inventory. Increases in the reserve are recorded as charges to cost of goods sold. As the Company does not have a history of experience of obtaining approval for and launching its drug products, the Company treats any pre-launch inventory that is manufactured for clinical trials or other purposes as research and development expense until objective and persuasive evidence exists that regulatory approval has been received and future economic benefit is probable. Therefore, all manufacturing costs for the production of Adzenys XR-ODT incurred after the January 27, 2016 FDA approval date are being capitalized into inventory. Deferred contract sales organization fees: The Company records fees billed in accordance with its commercial sales organization contract for services not yet performed as deferred contract sales organization fees. Such fees are recorded as selling and marketing expenses when the services are provided. Intangible assets : Intangible assets subject to amortization, which principally include proprietary modified-release drug delivery technology and the costs to acquire the rights to Tussionex ANDA, are recorded at cost and amortized over the estimated lives of the assets, which primarily range from 10 to 20 years. Contract sales organization payable: The Company records amounts billed in accordance with its commercial sales organization contract, but unpaid as of the balance sheet date, as a contract sales organization payable in current liabilities. Revenue recognition: Revenue is generated from product sales, recorded on a net sales basis. Product revenue is recognized when all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) price to the buyer is fixed and determinable; and (4) collectability is reasonably assured. Revenue from sales transactions where the buyer has the right to return the product is recognized at the time of sale only if (1) the price to the buyer is substantially fixed or determinable at the date of sale, (2) the buyer has paid for the product, or the buyer is obligated to pay for the product and the obligation is not contingent on resale of the product, (3) the buyer’s obligation to pay would not be changed in the event of theft or physical destruction or damage of the product, (4) the buyer acquiring the product for resale has economic substance apart from that provided by the Company, (5) the Company does not have significant obligations for future performance to directly bring about resale of the product by the buyer, and (6) the amount of future returns can be reasonably estimated. The Company sells its generic Tussionex to a limited number of pharmaceutical wholesalers. Pharmaceutical wholesalers buy drug products directly from manufacturers. Title to the product passes upon delivery to the wholesalers, when the risks and rewards of ownership are assumed by the wholesaler (freight on board destination). These wholesalers then resell the product to retail customers such as food, drug and mass merchandisers. Net product sales Net product sales for the Company’s generic Tussionex product represent total gross product sales less gross to net sales adjustments. Gross to net sales adjustments include wholesaler fees and estimated allowances for product returns, government rebates, chargebacks and prompt-payment discounts to be incurred on the selling price of the respective product sales. Wholesale distribution fees are incurred on the management of these products by wholesalers and are recorded within net product sales based on definitive contractual agreements. The Company estimates gross to net sales adjustments for allowances for product returns, government rebates and chargebacks based upon analysis of third-party information, including information obtained from the Company’s third party logistics provider (“3PL”), with respect to its inventory levels and sell-through to the wholesalers’ customers, data available from third parties regarding prescriptions written for the Company’s products, as well as actual experience as reported by the Company’s customers and previous commercialization partners. Due to estimates and assumptions inherent in determining the amount of returns, rebates and chargebacks, the actual amount of returns and claims for rebates and chargebacks may be different from the estimates, at which time reserves would be adjusted accordingly. Allowances and accruals are recorded in the same period that the related revenue is recognized. Product returns Wholesalers’ contractual return rights are limited to defective product, product that was shipped in error, product ordered by customer in error, product returned due to overstock, product returned due to dating or product returned due to recall or other changes in regulatory guidelines. The return policy for expired product allows the wholesaler to return such product starting six months prior to expiry date to twelve months post expiry date. Generic Tussionex product returns are estimated based upon data available from sales of the Company’s product by its former commercialization partner and from actual experience as reported by retailers. Historical trend of returns will be continually monitored and may result in future adjustments to such estimates. On August 26, 2014, the U.S. Drug Enforcement Agency (“DEA”) reclassified the Company’s generic Tussionex from a Schedule III controlled substance to a Schedule II controlled substance which had the effect of requiring unsold product at the wholesalers and the 3PL to either be relabeled or returned. This new ruling was effective October 6, 2014. As such, the Company established reserves for the estimated returns of such product outstanding at the wholesalers as of October 6, 2014. The Company had no inventory labeled as Schedule III at the 3PL as of the effective date. Medicaid rebates The Company’s products are subject to state government-managed Medicaid programs whereby discounts and rebates are provided to participating state governments. Estimated rebates payable under governmental programs, including Medicaid, are recorded as a reduction of revenue at the time revenues are recorded. Calculations related to these rebate accruals are estimated based on sales of the Company’s product by its former commercialization partner. Historical trend of Medicaid rebates will be continually monitored and may result in future adjustments to such estimates. Wholesaler Chargebacks The Company’s products are subject to certain programs with wholesalers whereby pricing on products is discounted below wholesaler list price to participating entities. These entities purchase products through wholesalers at the discounted price, and the wholesalers charge the difference between their acquisition cost and the discounted price back to the Company. Chargebacks are accounted for by establishing an accrual in an amount equal to the Company’s estimate of chargeback claims at the time of product sale based on information provided by the distributor. Due to estimates and assumptions inherent in determining the amount of chargebacks, the actual amount of claims for chargebacks may be different from estimates, which may result in adjustments to such reserves. Research and development costs: Research and development costs are charged to operations when incurred and include salaries and benefits, facilities costs, overhead costs, raw materials, laboratory and clinical supplies, clinical trial costs, contract services, fees paid to regulatory authorities for review and approval of the Company’s product candidates and other related costs. Income taxes: Income taxes are accounted for using the liability method, under which deferred taxes are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax laws that will be in effect when the differences are expected to reverse. Management evaluates the Company’s tax positions in accordance with guidance on accounting for uncertainty in income taxes. Using that guidance, tax positions initially need to be recognized in the financial statements when it is more likely than not that the position will be sustained upon examination. As of March 31, 2016 and December 31, 2015, the Company had no uncertain tax positions that qualify for either recognition or disclosure in the consolidated financial statements. Tax benefits are recognized when it is more likely than not that a tax position will be sustained during an audit. Deferred tax assets are reduced by a valuation allowance if current evidence indicates that it is considered more likely than not that these benefits will not be realized. At March 31, 2016 and December 31, 2015, based on the level of historical operating results and projections for the taxable income for the future, the Company has determined that it is more likely than not that the deferred tax assets will not be realized. Accordingly, the Company has recorded a valuation allowance to reduce deferred tax assets to zero. The Company may not ever be able to realize the benefit of some or all of the federal and state loss carryforwards, either due to ongoing operating losses or due to ownership changes, which limit the usefulness of the loss carryforwards. At December 31, 2015, the Company had a federal net operating loss carry-forward of $122,075,000 and research and development credits of $2,010,000, which begin to expire in 2024. The Company analyzed the impact of any ownership change(s) under Section 382 of the Internal Revenue Code and determined that the amount of federal net operating loss that will expire unused due to the Section 382 limitation is $6,089,000. The amount of federal research and development credit that will expire unused is $350,000. The deferred tax assets for both carryforwards have been adjusted downward accordingly. Warrants: The Company accounts for its warrants and other derivative financial instruments as either equity or liabilities based upon the characteristics and provisions of each instrument. Warrants classified as derivative liabilities are recorded on the Company’s balance sheet at their fair value on the date of issuance and are revalued at each subsequent balance sheet date, with fair value changes recognized as increases or reductions to other income (expense) in the statements of operations. The Company estimates the fair value of its derivative liabilities using third party valuation analysis that utilizes option pricing models and assumptions that are based on the individual characteristics of the warrants or instruments on the valuation date, as well as assumptions for expected volatility, expected life, yield, and risk-free interest rate. Prior to the closing of the IPO, the Company’s Series C warrants were determined to be derivative liabilities and they were revalued at each subsequent balance sheet date. Upon closing the IPO, the warrants issued in conjunction with the Series C preferred stock financing were exchanged in a cashless exercise for 947,185 shares of Series C preferred stock which converted into 78,926 shares of the Company’s common stock. The remaining Series C warrants issued with the senior debt to purchase 170,000 pre-split shares of Series C preferred stock (“Hercules Warrants”) were converted into warrants with a term of five years to purchase 70,833 shares of the Company’s common stock and the warrant liability was reclassified to Additional Paid in Capital within Stockholders’ Equity. Share-based compensation: Share-based compensation awards, including grants of employee stock options and restricted stock and modifications to existing stock options, are recognized in the statement of operations based on their fair values. Compensation expense related to awards to employees is recognized on a straight-line basis, based on the grant date fair value, over the requisite service period of the award, which is generally the vesting term. The fair value of the Company’s stock-based awards to employees and directors is estimated using the Black-Scholes option pricing model, which requires the input of subjective assumptions, including (1) the expected stock price volatility, (2) the expected term of the award, (3) the risk-free interest rate and (4) expected dividends. Due to the previous lack of a public market for the trading of its common stock and a lack of company-specific historical and implied volatility data, the Company has, prior to the IPO, historically utilized third party valuation analyses to determine the fair value. After the closing of our IPO, the Company’s board of directors has determined the fair value of each share of underlying common stock based on the closing price of our common stock as reported by the NASDAQ Global Market on the date of grant. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Ultimately, the actual expense recognized over the vesting period will only be for those options that vest. Use of estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates. Segment information: Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business in one operating segment, which is the development, manufacturing and commercialization of pharmaceuticals. Liquidity: During 2015 and the three months ended March 31, 2016, the Company produced operating losses and used cash to fund operations. Management intends to achieve profitability through revenue growth from pharmaceutical products developed with its extended-release technologies. The Company does not anticipate it will be profitable until after the launch of Adzenys XR-ODT or, if approved, one or more of its ADHD product candidates. Management believes the Company presently has sufficient liquidity to continue to operate for at least the next 12 months. Application of revised accounting standards: In April 2012, the Jumpstart Our Business Startups Act (the “JOBS Act”), was enacted in the United States. Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company has irrevocably elected not to avail itself of this extended transition period and, as a result, will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies. Recent accounting pronouncements: In March 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation — Stock Compensation — Improvements to Employee Share-Based Payment Accounting (Topic 718) . For public companies, areas of accounting for share-based payment that this ASU was designed to simplify include: the income tax consequences, the accounting policy for forfeitures, the classification of awards as either equity or liabilities and the classification on the statement of cash flows. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2016, including interim periods within those years. The Company is evaluating this ASU and has not determined the effect of this standard on its ongoing financial reporting. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: 1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and 2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The new lease guidance simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those years. The Company is evaluating this ASU and has not determined the effect of this standard on its ongoing financial reporting. In July 2015, the FASB issued ASU No. 2015-11, Inventory—Simplifying the Measurement of Inventory (Topic 330). The amendments in this ASU require an entity to measure inventory that is not measured using the last-in, first-out (LIFO) or retail inventory methods at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016, including interim periods within those years. The Company is evaluating this ASU and has not determined the effect of this standard on its ongoing financial reporting. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. This ASU is for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early application is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. The Company has performed the review required by this ASU and believes the Company presently has sufficient liquidity to continue to operate for the next twelve months. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard will become effective for the Company on January 1, 2018. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. Also, in March 2016 the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers — Principal versus Agent Considerations (Reporting Revenue Gross versus Net) to clarify the implementation guidance on principal versus agent considerations. This ASU states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Also, in April 2016 the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers — Identifying Performance Obligations and Licensing to assist preparers with identifying performance obligations and implementing licensing guidance under the new revenue standard. The amendments in ASU 2016-08 and 2016-10 have the same effective date and transition requirements as ASU 2014-09. The Company is evaluating the effect that ASU 2014-09, ASU 2016-08 and ASU 2016-10 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of these standards on its ongoing financial reporting. From time to time, additional new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective either are not applicable or will not have a material impact on its financial position or results of operations upon adoption. Reclassifications: Certain reclassifications have been made to the prior year’s consolidated financial statements to conform to the current year’s presentation. Subsequent events: The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. |
